AB Objective: To evaluate racial/ethnic differences in contraceptive use among women who do not desire future pregnancy.
Study Design: We used the 2006-2010 National Survey of Family Growth to examine the associations between race/ethnicity and 1) use of any contraceptive method at last heterosexual intercourse and 2) effectiveness of contraceptive method used among women who stated that they did not desire any (more) children. We conducted multivariable logistic regression to assess the independent effect of race/ethnicity on these outcomes, adjusting for socio-demographic factors, reproductive characteristics, and indicators of healthcare access and utilization.
Results: The study sample consisted of 2900 women, aged 15-44 years. The vast majority of women (91.2%) used contraception at last sex, although this varied significantly by race/ethnicity (p<.01). In the fully adjusted model controlling for demographic and reproductive characteristics as well as healthcare access, compared to whites, black women were significantly less likely to use any contraception at last sex (OR: 0.43; 95% CI: 0.27-0.73), while there was no significant difference for Hispanic women (OR: 0.95; 95% CI: 0.52-1.72). Among women who used a method at last sex, the type of contraceptive method varied significantly by race/ethnicity in bivariate analysis (p<.01), although most women (59%) used a highly effective method. In the fully adjusted model, racial/ethnic differences were no longer significant.
Conclusions: In this nationally representative cohort of women who report that they do not desire (more) children, black women were significantly less likely than white women to use any contraception at last intercourse; this difference did not appear to be due to differential access to health care.

AB Purpose:To evaluate the safety and efficacy of topical loteprednol etabonate (LE) 0.5% compared with cyclosporine A (CsA) 0.05% for the prophylaxis and treatment of dry eye syndrome (DES) after hematopoietic stem cell transplantation (HSCT).Methods:Seventy-five patients were randomized to LE (n = 76 eyes of 38 patients) or CsA (n = 74 eyes of 37 patients) pre-HSCT. Lissamine green and fluorescein staining, tear break-up time, tear osmolarity (Osm), Schirmer score (Sch), intraocular pressure, visual acuity, and Ocular Surface Disease Index were assessed pre-HSCT, 3, 6, 9, and 12 months post-HSCT.Results:There were no differences in DES incidence (P = 0.22; log-rank test) or progression (P = 0.41; log-rank test) between the 2 treatment arms during the course of the study. Among eyes with no DES at enrollment, the Kaplan-Meier analysis yielded a 90% rate of DES development in cyclosporine-treated eyes and a 79% rate of DES development in LE-treated eyes by 12 months post-HSCT. The Kaplan-Meier analysis of eyes with DES at enrollment demonstrated a 38% rate of disease progression among cyclosporine-treated eyes and a 26% rate of disease progression among loteprednol-treated eyes by 12 months. No patient in either group had an elevation of 10 mm Hg or greater from baseline at any study visit, and no patients had their treatment discontinued for elevation in intraocular pressure.Conclusions:Pre-HSCT initiation of LE 0.5% appears to be safe and may be as effective as CsA 0.5% for the treatment and prophylaxis of DES following HSCT.

AB As the technology of cytometry matures, there is mounting pressure to address two major issues with data analyses. The first issue is to develop new analysis methods for high-dimensional data that can directly reveal and quantify important characteristics associated with complex cellular biology. The other issue is to replace subjective and inaccurate gating with automated methods that objectively define subpopulations and account for population overlap due to measurement uncertainty. Probability state modeling (PSM) is a technique that addresses both of these issues. The theory and important algorithms associated with PSM are presented along with simple examples and general strategies for autonomous analyses. PSM is leveraged to better understand B-cell ontogeny in bone marrow in a companion Cytometry Part B manuscript. Three short relevant videos are available in the online supporting information for both of these papers. PSM avoids the dimensionality barrier normally associated with high-dimensionality modeling by using broadened quantile functions instead of frequency functions to represent the modulation of cellular epitopes as cells differentiate. Since modeling programs ultimately minimize or maximize one or more objective functions, they are particularly amenable to automation and, therefore, represent a viable alternative to subjective and inaccurate gating approaches.

AB BackgroundHuman progenitor and B-cell development is a highly regulated process characterized by the ordered differential expression of numerous cell-surface and intracytoplasmic antigens. This study investigates the underlying coordination of these modulations by examining a series of normal bone marrow samples with the method of probability state modeling or PSM.
ResultsThe study is divided into two sections. The first section examines B-cell stages subsequent to CD19 up-regulation. The second section assesses an earlier differentiation stage before and including CD19 up-regulation.
Post-CD19 Antigenic Up-RegulationStatistical analyses of cytometry data derived from sixteen normal bone marrow specimens revealed that B cells have at least three distinct coordinated changes, forming four stages labeled as B1, B2, B3, and B4. At the end of B1; CD34 antigen expression down-regulates with TdT while CD45, CD81, and CD20 slightly up-regulate. At the end of B2, CD45 and CD20 up-regulate. At the end of B3 and beginning of B4; CD10, CD38, and CD81 down-regulate while CD22 and CD44 up-regulate.
Pre-CD19 Antigenic Up-RegulationStatistical analysis of ten normal bone marrows revealed that there are at least two measurable coordinated changes with progenitors, forming three stages labeled as P1, P2, and P3. At the end of P1, CD38 up-regulates. At the end of P2; CD19, CD10, CD81, CD22, and CD9 up-regulate while CD44 down-regulates slightly.
ConclusionsThese objective results yield a clearer immunophenotypic picture of the underlying cellular mechanisms that are operating in these important developmental processes. Also, unambiguously determined stages define what is meant by normal B-cell development and may serve as a preliminary step for the development of highly sensitive minimum residual disease detection systems. A companion article is simultaneously being published in Cytometry Part A that will explain in further detail the theory behind PSM. Three short relevant videos are available in the online supporting information for both of these papers. (c) 2015 International Clinical Cytometry Society

AB Identification and isolation of hematopoietic stem cells (HSCs) in mice is most commonly based on the expression of surface molecules Kit and Sca-1 and the absence of markers of mature lineages. However, Sca-1 is absent or weakly expressed in hematopoietic progenitors in many strains, including nonobese diabetic (NOD), BALB/c, C3H, and CBA mice. In addition, both Kit and Sca-1 levels are modulated following bone marrow injury. In these cases, other markers and dye exclusion methods have been employed to identify HSCs, yet there is no antibody-based stain that enables identification of HSCs and early progenitors when Kit and Sca-1 are inadequate. CD201 is a marker that is highly restricted to HSCs and progenitors, and CD27 is expressed at moderate-to-high levels on HSCs. We show here that combining CD201 and CD27 enables highly efficient isolation of long-term HSCs in NOD mice as well as in other strains, including SJL, FVB, AKR, BALB/c, C3H, and CBA. We also find that HSCs appear to maintain expression of CD201 and CD27 after hematopoietic injury when Kit expression is downregulated. These results suggest a widely applicable yet simple alternative for HSC isolation in settings where Kit and Sea-1 expression are insufficient.

AB Outcomes for patients with multiple myeloma (MM) have improved significantly over the past decade. Despite these advances, MM remains incurable and an unmet medical need remains for patients who are relapsed and/or refractory. Panobinostat is a potent, oral pan-deacetylase inhibitor that elicits anti-myeloma activity through epigenetic modulation of gene expression and disruption of protein metabolism. Preclinical data demonstrated that panobinostat has synergistic effects on myeloma cells when combined with bortezomib and dexamethasone. In a Phase III clinical trial evaluating bortezomib and dexamethasone in combination with panobinostat or placebo in patients with relapsed or relapsed and refractory MM (PANORAMA 1), panobinostat led to a significant increase in median progression-free survival. Panobinostat is currently under regulatory review with a recent accelerated approval granted for the treatment of relapsed disease, in which both bortezomib and immunomodulatory drugs have failed. Here, we summarize the preclinical, pharmacokinetic and clinical data for panobinostat in MM.

AB Acute respiratory infections (ARIs), such as bronchiolitis and pneumonia, are the leading cause of hospitalization of infants in the US. While the incidence and severity of ARI can vary widely among children, the reasons for these differences are not fully explained by traditional risk factors (e. g., prematurity, viral pathogens). The recent advent of molecular diagnostic techniques has revealed the presence of highly functional communities of microbes inhabiting the human body (i.e., microbiota) that appear to influence development of local and systemic immune response. We propose a 'risk and resilience' model in which airway microbiota are associated with an increased (risk microbiota) or decreased (resilience microbiota) incidence and severity of ARI in children. We also propose that modulating airway microbiota (e. g., from risk to resilience microbiota) during early childhood will optimize airway immunity and, thereby, decrease ARI incidence and severity in children.

AB Portopulmonary hypertension (POPH) is a complication of portal hypertension characterized by pulmonary vasoconstriction and vascular remodeling that can lead to right heart failure and death. Differentiation of POPH from other causes of pulmonary hypertension, such as volume overload or a hyperdynamic high flow state, is critical because a diagnosis of POPH has significant implications for liver transplant risk stratification, Model for End Stage Liver Disease exception points, and the use of pulmonary arterial hypertension-(PAH) specific therapy. Currently, there are 12 approved medications for the treatment of PAH in the US, and three of these were approved in 2013. This review will discuss the diagnosis, evaluation and management of POPH and the role of recently approved PAH therapies in the treatment of POPH.

AB Objective. The purpose of this multicenter, open label, randomized phase III study was to determine whether ixabepilone resulted in improved overall survival (OS) compared with commonly used single-agent chemotherapy (doxorubicin or paclitaxel) in women with locally advanced, recurrent, or metastatic endometrial cancer with at least one failed prior platinum-based chemotherapeutic regimen.
Methods. Patients were randomized 1:1 to ixabepilone (40 mg/m(2)), or either paclitaxel (175 mg/m(2)) or doxorubicin (60 mg/m(2)), every 21 days. Patients that had previously received an anthracycline were randomized to ixabepilone or paclitaxel; all other patients were randomized to ixabepilone or doxorubicin. An interim analysis of futility for OS was planned.
Results. At the time of database lock, 496 patients were randomized to receive ixabepilone (n = 248) or control (n = 248); nine patients in the control arm were not treated. The interim analysis of futility for OS (219 events) favored the control chemotherapy arm (hazard ratio = 1.3 [95% confidence interval: 1.0-1.7], stratified log rank test P = 0.0397), indicating that the study would not meet its primary objective. The study was discontinued based on the interim OS results. The frequency of adverse events was comparable between the treatment arms.
Conclusions. The study did not meet its primary objective of improving OS in the ixabepilone arm compared to the control chemotherapy arm. A favorable risk/benefit ratio was not observed for ixabepilone versus control at the time of the interim analysis. The safety results were consistent with the known safety profiles of ixabepilone and control. (C) 2015 Elsevier Inc. All rights reserved.

TI Changing presentation of complete hydatidiform mole at the New England
Trophoblastic Disease Center over the past three decades: Does early
diagnosis alter risk for gestational trophoblastic neoplasia?
SO GYNECOLOGIC ONCOLOGY
LA English
DT Article
DE Gestational trophoblastic disease; Gestational trophoblastic neoplasia
ID PREGNANCY; FEATURES
AB Objective. To compare the clinical presentation and incidence of postmolar gestational trophoblastic neoplasia (GTN) among recent (1994-2013) and historical (1988-1993) cases of complete hydatidiform mole (CHM).
Methods. This study included two non-concurrent cohorts (1988-1993 versus 1994-2013) of patients from the New England Trophoblastic Disease Center (NETDC). Clinical and pathologic reports of patients diagnosed with CHM between 1994 and 2013 were reviewed. Gestational age at evacuation, features of clinical presentation, human chorionic gonadotropin (hCG) levels, and the rate of progression to GTN were compared.
Results. In the current cohort (1994 to 2013) the median gestational age at diagnosis continued to decline compared to our prior cohort (1988-1993) (9 weeks versus 12 weeks). Patients from the current cohort were significantly more likely to be diagnosed prior to the 11th week of gestation (56 versus 41%, p = 0.04). Patients in the current cohort were also significantly less likely to present with vaginal bleeding (46 versus 84%, p < 0.001). Earlier diagnosis of complete mole did not result in a decrease in the rate of postmolar GTN. The frequencies of postmolar GTN in the current (1994-2013) and prior (1988-1993) cohorts were 19 and 23%, respectively. In the current cohort, even diagnosis prior to ten weeks gestation did not decrease the risk of developing GTN.
Conclusions. This study indicates that complete mole continues to be diagnosed progressively earlier resulting in a further decrease in some classical presenting symptoms. However, despite earlier detection, the risk of development of postmolar GTN has not been affected. (C) 2015 Elsevier Inc. All rights reserved.

AB Objective. To evaluate the potential effects of race on clinical characteristics, extent of disease, and response to chemotherapy in women with postmolar low-risk gestational trophoblastic neoplasia (GTN).
Methods. This non-concurrent cohort study was undertaken including patients with FIGO-defined postmolar low-risk GTN treated with comparable doses and schedules of chemotherapy at the New England Trophoblastic Disease Center (NETDC) between 1973 and 2012. Racial groups investigated included whites, African American and Asians. Information on patient characteristics and response to chemotherapy (need for second line chemotherapy, reason for changing to an alternative chemotherapy, number of cycles/regimens, need for combination chemotherapy, and time to hCG remission) was obtained.
Results. Of 316 women, 274 (86.7%) were white, 19 (6%) African American, and 23 (7.3%) Asian. African Americans were significantly younger than white and Asian women (p = 0.008). Disease presentation, and extent of disease, including antecedent molar histology, median time to persistence, median hCG level at persistence, rate of D&C at persistence, presence of metastatic disease, and FIGO stage and risk score were similar among races. Need for second line chemotherapy (p = 0.023), and median number of regimens (p = 0.035) were greater in Asian women than in other races.
Conclusions. Low-risk GTN was more aggressive in Asian women, who were significantly more likely to need second line chemotherapy and a higher number of chemotherapy regimens to achieve complete remission than women of African American and Asian descent. Further studies involving racial differences related to clinical, biological and environmental characteristics are needed. (C) 2015 Published by Elsevier Inc.

AB Objective. To describe the effects of obesity on the pharmacokinetics and dosing of chemotherapies and provide recommendations for chemotherapy management in obese women with gynecologic malignancies.
Methods. PubMEd and MEDLINE databases were searched for articles published before June 2014. Only English-language articles were considered. 84 manuscripts were reviewed and 66 were included. Search terms included: obesity, overweight, body mass index, body surface area, glomerular filtration rate, chemotherapy, ovarian cancer, endometrial cancer, inflammation, and pharmacokinetics.
Results. Obese cancer patients have worse clinical outcomes, compared with non-obese patients. This may be because of differences in pharmacokinetics, metabolic dysregulation, or physicians' decisions to reduce chemotherapy dose-intensity during treatment to minimize toxicities. A 2012 American Society of Clinical Oncology Clinical Practice Guideline recommends using actual body weight for chemotherapy dosing in all patients treated with curative intent, irrespective of obesity, to avoid compromising clinical outcomes, including progression free survival (PFS) and overall survival (OS). In women with gynecologic cancers most studies demonstrate no difference in PFS or OS when obese patients receive the same chemotherapy dose intensity as non-obese patients, except perhaps with bevacizumab.
Conclusions. Chemotherapy dose-intensity is a critical determinant of cancer outcomes and should be maintained in all patients, irrespective of obesity. Future studies should prospectively examine the impact of obesity on clinical outcomes (adverse events, survival) to improve the care of this growing population of patients who are at risk for inferior clinical outcomes.

AB Despite a concerning decline in the use of brachytherapy over the past decade, no other therapy is able to deliver a very high dose of radiation into or near a tumor, with a rapid fall-off of dose to adjacent structures. Compared to traditional X-ray-based brachytherapy that relies on points, the use of CT and MR for 3D planning of gynecologic brachytherapy provides a much more accurate volume-based calculation of dose to an image-defined tumor and to the bladder, rectum, sigmoid, and other pelvic organs at risk (OAR) for radiation complications. The publication of standardized guidelines and an online contouring teaching atlas for performing 3D image-based brachytherapy has created a universal platform for communication and training. This has resulted in a uniform approach to using image-guided brachytherapy for treatment and an internationally accepted format for reporting clinical outcomes. Significant improvements in survival and reductions in toxicity have been reported with the addition of image guidance to increase dose to tumor and decrease dose to the critical OAR. Future improvements in individualizing patient treatments should include a more precise definition of the target. This will allow dose modulation based on the amount of residual disease visualized on images obtained at the time of brachytherapy. (C) 2015 Elsevier Inc. All rights reserved.

AB BackgroundThe purpose of this study was to investigate the role of transcutaneous neuromuscular electrical stimulation (TNMES) therapy in maintaining swallowing function during chemoradiation for locally advanced head and neck cancer.
MethodsWe retrospectively compared 43 consecutive patients with locally advanced head and neck cancer treated with TNMES (treatment group) to 55 control patients. Validated swallowing scale scores were assigned.
ResultsAll patients' swallowing scores declined post-chemoradiotherapy. A difference in mean decline in scores for the control group versus the treatment group using the Functional Oral Intake Scale (FOIS) was seen, favoring TNMES intervention (23% vs 7%; p = .015). Age, race, >10 pack-years smoking, diabetes, stage, nodal disease, accelerated fractionation, weight loss, dietary modification, no TNMES, and radiotherapy dose were all significant for poorer scores on the swallowing scales.
ConclusionTNMES should be considered an adjunct to dysphagia reduction and possible prevention in patients with locally advanced head and neck cancer. Further studies should be conducted to define the benefit of TNMES intervention. (c) 2015 Wiley Periodicals, Inc. Head Neck 37: 1051-1056, 2015

AB BACKGROUND Watchman and Lariat left atrial appendage (LAA) occlusion devices are associated with LAA leaks postdeployment.
OBJECTIVE The purpose of this study was to compare the incidence, characteristics, and clinical significance of these leaks.
METHODS We performed a multicenter prospective observational study of all patients who underwent LAA closure. Baseline, procedural, and imaging variables along with LAA occlusion rates at 30-90 days and 1-year postprocedure were compared.
RESULTS A total of 478 patients (219 with the Watchman device and 259 with the Lariat device) with successful implants were included. Patients in the Lariat group had a higher CHADS(2) (congestive heart failure, hypertension, age >74 years, diabetes, stroke) score and a larger left atrium and LAA. A total of 79 patients (17%) had a detectable leak at 1 year. More patients in the Watchman group had a leak compared with those in the Lariat group (46 [21%] vs 33 [14%]; P = .019). All the leaks were eccentric (edge effect) in the Watchman group and concentric (gunny sack effect) in the Lariat group. The size of the leak was Larger in the Watchman group than in the Lariat group (3.10 +/- 1.5 mm vs 2.15 +/- 1.3 mm; P = .001). The Watchman group had 1 device embolization requiring surgery and 2 pericardial effusions requiring pericardiocentesis. In the Lariat group, 4 patients had cardiac tamponade requiring urgent surgical repair. Three patients in each group had a cerebrovascular accident and were not associated with device Leaks.
CONCLUSION The Lariat device is associated with a lower rate of leaks at 1 year as compared with the Watchman device, with no difference in rates of cerebrovascular accident. There was no correlation between the presence of residual leak and the occurrence of cerebrovascular accident.

AB Despite the efficacy and success of targeted therapies, a significant number of patients with melanoma exhibit either intrinsic or acquired resistance to these drugs. Numerous mechanisms for the development of resistance have been postulated, but the precise reason for this is not known. In this review, we examine the incidence of mutations in select genes (BRAF, NRAS, C-KIT, and GNAQ) known to occur in melanoma, specifically in primary tumors and their paired metastases, to understand the significance of intratumoral heterogeneity by assessing how changes in mutation status alters the process of metastatic spread.
Our data revealed a small yet consistent degree of discordance of mutations in the MAPK pathway commonly occurring in melanoma indicating that failed targeted therapy may be a consequence of this.

AB CXCR3 is a G-protein coupled receptor which binds to ELR-negative CXC chemokines that have been found to impact immune responses, vascular develop, and wound repair. More recently, CXCR3 has been examined in the context of cancer and increased expression in many human tumors has been correlated with poor prognosis in breast, melanoma, colon and renal cancer patients. Three variants of CXCR3 are identified so far (CXCR3-A, CXCR3-B and CXCR3-alt) with the two primary ones, CXCR3-A and CXCR3-B, considered to induce opposite physiological functions. Generally, CXCR3-A, the predominant form in hematopoietic cells, appears to mediate tumor "go" signaling via promoting cell proliferation, survival, chemotaxis, invasion and metastasis; while CXCR3-B, the main form on formed elements including epithelial cells, appears to mediate tumor "stop" signaling via promoting growth suppression, apoptosis and vascular involution. Thus, aberrant expression of the isoforms CXCR3-A and CXCR3-B could affect tumor progression. In this review, we have discussed the profiles of CXCR3 variants and related signaling, as well as the role of CXCR3 variants in cancer.

AB Giant cell tumors, a well-recognized neoplasm of bone, can rarely be found in the uterus. Such tumors are characterized by a dual population of mononuclear and osteoclast-like giant cells that lack epithelial and specific mesenchymal differentiation. In this study, the clinicopathologic features of 3 giant cell tumors of the uterus were reviewed. Immunohistochemistry for CD68, CD163, h-caldesmon, desmin, SMA, AE1/AE3, CD10, ER, PR, cyclin D1, CD1a, CD34, CD30, S100, myogenin/myoglobin, and Ki-67 was performed in all tumors, along with ultrastructural analysis in one. The patients were 47, 57, and 59 yr and the tumors measured 2.5, 7.5, and 16.0 cm. One neoplasm was confined to the endometrium, whereas the other 2 were myometrial. All 3 tumors showed a nodular growth comprised of mononuclear and osteoclast-like giant cells. The endometrial-confined tumor consisted of histologically benign mononuclear cells, whereas the others exhibited marked atypia. Mitotic activity was up to 5/10 HPF in the benign tumor and up to 22/10 HPF in the malignant. No cytologic atypia or mitoses were observed in the giant cells. CD68 and CD10 were strongly and diffusely expressed in both components of 3 and 2 neoplasms, respectively. Cyclin D1 was focal in the mononuclear cells and focal to diffuse in the giant cells. CD163 was diffuse in the mononuclear cells, but absent to focal in the giant cells. Ultrastructural analysis lacked diagnostic features of epithelial or specific mesenchymal differentiation. Both malignant tumors demonstrated an aggressive behavior. In summary, although rare, giant cell tumor of the uterus should be included in the differential diagnosis of benign or malignant tumors containing osteoclast-like giant cells.

AB Ovarian tumors encountered during pregnancy can pose a diagnostic challenge due to an abundance of luteinized cells and other changes. We report 8 sclerosing stromal tumors with massive luteinization discovered in pregnant patients. The tumors ranged from 3.1 to 21 cm (mean=8.8 cm) in size and were typically solid and yellow; the neoplasm was bilateral in 1 case. On microscopic examination, the lutein cells, a feature of sclerosing stromal tumor, had more copious eosinophilic cytoplasm and were more numerous than is usually seen in nonpregnant patients and to varying degrees obscured the typical pseudolobular pattern. This resulted in particular diagnostic difficulty in 3 cases, especially when associated with other changes including irregular shapes of tumor cell nests, edema, and/or myxoid change. However, classic features of these tumors: ectatic vessels and admixed luteinized and nonluteinized cells were still focally evident, allowing for accurate classification. The tumors were cytologically bland and with 1 exception had rare mitoses. As sclerosing stromal tumors have been invariably benign, it is important that they not be confused with other tumors, such as steroid cell tumor, which can occasionally be malignant.

AB To examine prospectively the association between US state income inequality and incidence of heart attack.
We used data from the National Epidemiologic Survey on Alcohol and Related Conditions (n = 34,445). Respondents completed interviews at baseline (2001-2002) and follow-up (2004-2005). Weighted multilevel modeling was used to determine if US state-level income inequality (measured by the Gini coefficient) at baseline was a predictor of heart attack during follow-up, controlling for individual-level and state-level covariates.
In comparison to residents of US states in the lowest quartile of income inequality, those living in the second [Adjusted Odds Ratio (AOR) = 1.71, 95 % CI 1.16-2.53)], third (AOR = 1.81, 95 % CI 1.28-2.57), and fourth (AOR = 2.04, 95 % CI 1.26-3.29) quartiles were more likely to have a heart attack. Similar findings were obtained when we excluded those who had a heart attack prior to baseline.
This study is one of the first to empirically show the longitudinal relationship between income inequality and coronary heart disease. Living in a state with higher income inequality increases the risk for heart attack among US adults.

AB Background and AimsThe Houston Intra-Arterial Therapy score predicts poor functional outcome following endovascular treatment for acute ischemic stroke based on clinical variables. The present study sought to (a) create a predictive scoring system that included a neuroimaging variable and (b) determine if the scoring systems predict the clinical response to reperfusion.
MethodsSeparate datasets were used to derive (n=110 from the Diffusion and Perfusion Imaging Evaluation for Understanding Stroke Evolution 2 study) and validate (n=125 from Massachusetts General Hospital) scoring systems that predict poor functional outcome, defined as a modified Rankin Scale score of 4-6 at 90 days.
ResultsAge (P<0001; =0087) and diffusion-weighted imaging volume (P=0023; =0025) were the independent predictors of poor functional outcome. The Stanford Age and Diffusion-Weighted Imaging score was created based on the patient's age (0-3 points) and diffusion-weighted imaging lesion volume (0-1 points). The percentage of patients with a poor functional outcome increased significantly with the number of points on the Stanford Age and Diffusion-Weighted Imaging score (P<001 for trend). The area under the receiver operating characteristic curve for the Stanford Age and Diffusion-Weighted Imaging score was 082 in the derivation dataset. In the validation cohort, the area under the receiver operating characteristic curve was 069 for the Stanford Age and Diffusion-Weighted Imaging score and 066 for the Houston Intra-Arterial Therapy score (P=045 for the difference). Reperfusion, but not the interactions between the prediction scores and reperfusion, were predictors of outcome (P>05).
ConclusionsThe Stanford Age and Diffusion-Weighted Imaging and Houston Intra-Arterial Therapy scores can be used to predict poor functional outcome following endovascular therapy with good accuracy. However, these scores do not predict the clinical response to reperfusion. This limits their utility as tools to select patients for acute stroke interventions.

AB BackgroundTo assess the differences across continental regions in terms of stroke imaging obtained for making acute revascularization therapy decisions, and to identify obstacles to participating in randomized trials involving multimodal imaging.
MethodsSTroke Imaging Repository (STIR) and Virtual International Stroke Trials Archive (VISTA)-Imaging circulated an online survey through its website, through the websites of national professional societies from multiple countries as well as through email distribution lists from STIR and the above mentioned societies.
ResultsWe received responses from 223 centers (2 from Africa, 38 from Asia, 10 from Australia, 101 from Europe, 4 from Middle East, 55 from North America, 13 from South America). In combination, the sites surveyed administered acute revascularization therapy to a total of 25326 acute stroke patients in 2012. Seventy-three percent of these patients received intravenous (IV) tissue plasminogen activator (tPA), and 27%, endovascular therapy. Vascular imaging was routinely obtained in 79% (152/193) of sites for endovascular therapy decisions, and also as part of standard IV tPA treatment decisions at 46% (92/198) of sites. Modality, availability and use of acute vascular and perfusion imaging before revascularization varied substantially between geographical areas. The main obstacles to participate in randomized trials involving multimodal imaging included: mainly insufficient research support and staff (50%, 79/158) and infrequent use of multimodal imaging (27%, 43/158) .
ConclusionThere were significant variations among sites and geographical areas in terms of stroke imaging work-up used tomake decisions both for intravenous and endovascular revascularization. Clinical trials using advanced imaging as a selection tool for acute revascularization therapy should address the need for additional resources and technical support, and take into consideration the lack of routine use of such techniques in trial planning.

AB Purpose Adequate comorbidity risk adjustment is central for reliable outcome prediction and provider performance evaluation. The two most commonly employed risk-adjustment methods in orthopaedic surgery were not originally validated in this patient population. We sought (1) to develop a single numeric comorbidity score for predicting inpatient mortality in patients undergoing orthopaedic surgery by combining and reweighting the conditions included in the Charlson and Elixhauser measures, and to compare its predictive performance to each of the separate component scores. We also (2) evaluated the new score separately for spine surgery, adult reconstruction, hip fracture, and musculoskeletal oncology admissions.
Methods Data from the National Hospital Discharge Survey for the years 1990 through 2007 were obtained. A comorbidity score for predicting inpatient mortality was developed by combining conditions from the Charlson and Elixhauser measures. Weights were derived from a random sample of 80 % of the cohort (n = 26,454,972), and the predictive ability of the new score was internally validated on the remaining 20 % (n = 6,739,169). Performance of scores was assessed and compared using the area under the receiver operating characteristic curve (AUC) derived from multivariable logistic regression models.
Results The new combined comorbidity score (AUC = 0.858, 95 % CI 0.856-0.859) performed 58 % better than the Charlson score (AUC = 0.794, 95 % CI 0.792-0.796) and 12 % better than the Elixhauser score (AUC = 0.845, 95 % CI 0.844-0.847). Of the seven conditions that received the highest weights in the new combined score, only three of them were included in both the Charlson and the Elixhauser indices. The new combined score achieved higher discriminatory power for all orthopaedic admission subgroups.
Conclusion A single numeric comorbidity score combining conditions from the Charlson and Elixhauser models provided better discrimination of inpatient mortality than either of its constituent scores. Future research should test this score in other populations and data settings.

AB The objective of this study was to assess the ability of tissue engineered cartilage to adhere to and integrate with porous polyethylene (PPE) in vivo and to evaluate the biomechanical integrity of the bond formed at the interface. Porcine auricular, articular, and costal chondrocytes were suspended in fibrin gel polymer and placed between discs of PPE to form tri-layer constructs. Controls consisted of fibroblasts suspended in gel or gel alone between the discs. Constructs were implanted into nude mice for 6, 12, and 18 weeks. Upon harvest, specimens were evaluated for neocartilage formation and integration into the PPE, using histological, dimensional (mass, thickness, diameter), and biomechanical (adhesion strength, interfacial stiffness, failure energy and failure strain) analyses. Neotissue was formed in all experimental constructs, consisting mostly of neocartilage integrating with discs of PPE. Control samples contained only fibrous tissue. Biomechanical analyses demonstrated that adhesion strength, interfacial stiffness, and failure energy were all significantly higher in the chondrocyte-seeded samples than in fibroblast-seeded controls, with the exception of costal constructs at 12 weeks, which were not significantly greater than controls. In general, failure strains did not vary between groups. In conclusion, porous polyethylene supported the growth of neocartilage that formed mechanically functional bonds with the PPE.

AB Denosumab (DMAb) administration to postmenopausal women with osteoporosis is associated with continued bone mineral density (BMD) increases and low fracture incidence through 8 years, despite persistently reduced bone turnover markers and limited fluorochrome labeling in iliac crest bone biopsies. BMD increases were hypothesized to result from additional accrual of bone matrix via modeling-based bone formationa hypothesis that was tested by examining fluorochrome labeling patterns in sections from ovariectomized (OVX) cynomolgus monkeys (cynos) treated with DMAb for 16 months. Mature OVX or Sham cynos were treated monthly with vehicle for 16 months, whereas other OVX cynos received monthly 25 or 50mg/kg DMAb. DMAb groups exhibited very low serum bone resorption and formation biomarkers and near-absent fluorochrome labeling in proximal femur cancellous bone. Despite these reductions, femoral neck dual-energy X-ray absorptiometry (DXA) BMD continued to rise in DMAb-treated cynos, from a 4.6% increase at month 6 to 9.8% above baseline at month 16. Further examination of cortical bone in the proximal femur demonstrated consistent and prominent labeling on the superior endocortex and the inferior periosteal surface, typically containing multiple superimposed labels from month 6 to 16 over smooth cement lines, consistent with continuous modeling-based bone formation. These findings were evident in all groups. Quantitative analysis at another modeling site, the ninth rib, demonstrated that DMAb did not alter the surface extent of modeling-based labels, or the cortical area bound by them, relative to OVX controls, while significantly reducing remodeling-based bone formation and eroded surface. This conservation of modeling-based formation occurred concomitantly with increased femoral neck strength and, when coupled with a reduction in remodeling-based bone loss, is likely to contribute to increases in bone mass with DMAb treatment. Thus, this study provides preclinical evidence for a potential mechanism that could contribute to the clinical observations of continued BMD increases and low fracture rates with long-term DMAb administration.

AB We describe an atypical man with diffuse large B cell lymphoma localized to the sphenoid wing and adjacent cavernous sinus, initially presenting with isolated ipsilateral facial pain mimicking trigeminal neuralgia due to invasion of Meckel's cave but subsequently progressing to intra-axial extension and having synchronous features of systemic lymphoma. Primary central nervous system lymphoma is uncommon, accounting for approximately 2% of all primary intracranial tumors, but its incidence has been steadily increasing in some groups [1]. It usually arises in the periventricular cerebral white matter, and reports of lymphoma in extra-axial regions are rare [2]. This man highlights the importance of maintaining lymphoma in the differential diagnosis of tumors of the skull base presenting with trigeminal neuralgia-like symptoms. (C) 2015 Elsevier Ltd.

AB Background: Investigations into personal factors influencing quality of life are important for those developing strategies to support patients with diabetes. This study aimed to investigate the influence of meaning of illness on quality of life in patients with type 2 diabetes.
Methods: Veterans from primary care clinics in the southeastern United States completed a questionnaire including questions from the validated 5-scale Meaning of Illness Questionnaire (MIQ). Unadjusted and adjusted linear regression models investigated the physical and mental components of quality of life with the 5 MIQ factors.
Results: The sample comprised 302 Black and White veterans. The physical component of quality of life (PCS) was positively associated with type of stress/attitude of harm (beta = 2.43, CI: 0.94 to 3.93) and challenge/motivation/hope (beta = 3.02, CI: 0.40 to 5.64) after adjustment, whereas the mental component of quality of life (MCS) was positively associated with the degree of stress/change in commitment (beta = 2.58, CI: 0.78 to 438), and negatively associated with challenge/motivation/hope (beta = -2.55, CI: -4.99 to -0.11).
Conclusion: Attitudes of challenge, motivation and hope had opposite effects on mental and physical components of quality of life in this sample of veterans. Additionally, whereas, the type of stress and attitude towards harm or loss was associated with the physical component, the degree of stress and change in commitments was associated with the mental component This suggests addressing the meaning of an illness may be complex but is an important consideration in improving both physical and mental components of quality of life in patients with type 2 diabetes.

TI Canadian Open Genetics Repository (COGR): a unified clinical genomics
database as a community resource for standardising and sharing genetic
interpretations
SO JOURNAL OF MEDICAL GENETICS
LA English
DT Article
ID SEQUENCE
AB Background The Canadian Open Genetics Repository is a collaborative effort for the collection, storage, sharing and robust analysis of variants reported by medical diagnostics laboratories across Canada. As clinical laboratories adopt modern genomics technologies, the need for this type of collaborative framework is increasingly important.
Methods A survey to assess existing protocols for variant classification and reporting was delivered to clinical genetics laboratories across Canada. Based on feedback from this survey, a variant assessment tool was made available to all laboratories. Each participating laboratory was provided with an instance of GeneInsight, a software featuring versioning and approval processes for variant assessments and interpretations and allowing for variant data to be shared between instances. Guidelines were established for sharing data among clinical laboratories and in the final outreach phase, data will be made readily available to patient advocacy groups for general use.
Results The survey demonstrated the need for improved standardisation and data sharing across the country. A variant assessment template was made available to the community to aid with standardisation. Instances of the GeneInsight tool were provided to clinical diagnostic laboratories across Canada for the purpose of uploading, transferring, accessing and sharing variant data.
Conclusions As an ongoing endeavour and a permanent resource, the Canadian Open Genetics Repository aims to serve as a focal point for the collaboration of Canadian laboratories with other countries in the development of tools that take full advantage of laboratory data in diagnosing, managing and treating genetic diseases.

AB Brown adipose tissue (BAT) has well recognized thermogenic properties mediated by uncoupling protein 1 (UCP1); more recently, BAT has been demonstrated to modulate cardiovascular risk factors. To investigate whether BAT also affects myocardial injury and remodeling, UCP1-deficient (UCP1(-/-)) mice, which have dysfunctional BAT, were subjected to catecholamine-induced cardiomyopathy. At baseline, there were no differences in echocardiographic parameters, plasma cardiac troponin I (cTnI) or myocardial fibrosis between wild-type (WT) and UCP1(-/-) mice. Isoproterenol infusion increased cTnI and myocardial fibrosis and induced left ventricular (LV) hypertrophy in both WT and UCP1(-/-) mice. UCP1(-/-) mice also demonstrated exaggerated myocardial injury, fibrosis, and adverse remodeling, as well as decreased survival. Transplantation of WT BAT to UCP1(-/-) mice prevented the isoproterenol-induced cTnI increase and improved survival, whereas UCP1(-/-) BAT transplanted to either UCP1(-/-) or WT mice had no effect on cTnI release. After 3 days of isoproterenol treatment, phosphorylated AKT and ERK were lower in the LV's of UCP1(-/-) mice than in those of WT mice. Activation of BAT was also noted in a model of chronic ischemic cardiomyopathy, and was correlated to LV dysfunction. Deficiency in UCP1, and accompanying BAT dysfunction, increases cardiomyocyte injury and adverse LV remodeling, and decreases survival in a mouse model of catecholamine-induced cardiomyopathy. Myocardial injury and decreased survival are rescued by transplantation of functional BAT to UCP1(-/-) mice, suggesting a systemic cardioprotective role of functional BAT. BAT is also activated in chronic ischemic cardiomyopathy. (C) 2015 Elsevier Ltd. All rights reserved.

AB PurposeThis article examines the evolution of Doctor of Nursing Science (DNS or DNSc) and Doctor of Science in Nursing (DSN) degrees, including their emergence as research-intensive doctoral degrees in the 1960s, efforts to distinguish the degrees from the Doctor of Philosophy (PhD) and Doctor of Nursing Practice (DNP) degrees, the recent decline in program numbers, and implications for degree holders.
ApproachThe article reviews the U.S. history of doctoral education in nursing, research examining similarities and differences between the PhD and DNS, DNSc, or DSN degrees, and how the DNS, DNSc, or DSN degree differs from DNP programs. The article also examines the confusion regarding the focus of the DNS, DNSc, or DSN degree among nurses, patients, and potential funders; and describes actions taken by universities to address the confusion, with examples provided by academic deans, nurse leaders, and nurse researchers.
FindingsLongstanding confusion about the research merits of the DNS, DNSc, or DSN degree, and the growing prominence of the similarly-titled DNP degree, has created confusion about the focus of DNS, DNSc, or DSN programs and the capabilities of degree holders. Many universities have addressed this confusion by converting their DNS, DNSc, and DSN programs to a PhD or retroactively converting degrees to a PhD. Other universities have chosen not to pursue this route.
ConclusionsThe DNS, DNSc, or DSN experience highlights the importance of clarifying and standardizing the purpose and goals of nursing education programs and the repercussions for degree holders when such clarity is lacking. The international academic nursing communities have consistently pursued one doctoral-level nursing degree and therefore have not shared this challenging landscape in nursing education.
Clinical RelevanceFindings and recommendations presented in this article have implications for schools of nursing and professional groups that oversee the development of educational programs and pathways for nurses.

ID TEAMWORK TRAINING IMPROVES; CARE; PERFORMANCE; MULTIDISCIPLINARY;

AB OBJECTIVE: Trauma team training provides instruction on crisis management through debriefing and discussion of teamwork and leadership skills during simulated trauma scenarios. The effects of team leader's nontechnical skills (NTSs) on technical performance have not been thoroughly studied. We hypothesized that team's and team leader's NTSs correlate with technical performance of clinical tasks.
DESIGN: Retrospective cohort study.
SETTING: Brigham and Women's Hospital, STRATUS Center for Surgical Simulation
PARTICIPANTS: A total of 20 teams composed of surgical residents, emergency medicine residents, emergency department nurses, and emergency services assistants underwent 2 separate, high-fidelity, simulated trauma scenarios. Each trauma scenario was recorded on video for analysis and divided into 4 consecutive sections. For each section, 2 raters used the Non-Technical Skills for Surgeons framework to assess NTSs of the team. To evaluate the entire team's NTS, 2 additional raters used the Modified Non-Technical Skills Scale for Trauma system. Clinical performance measures including adherence to guidelines and time to perform critical tasks were measured independently.
RESULTS: NTSs performance by both teams and team leaders in all NTS categories decreased from the beginning to the end of the scenario (all p < 0.05). There was significant correlation between team's and team leader's cognitive skills and critical task performance, with correlation coefficients between 0.351 and 0.478 (p < 0.05). The NTS performance of the team leader highly correlated with that of the entire team, with correlation coefficients between 0.602 and 0.785 (p < 0.001).
CONCLUSIONS: The NTSs of trauma teams and team leaders deteriorate as clinical scenarios progress, and the performance of team leaders and teams is highly correlated. Cognitive NTS scores correlate with critical task performance. Increased attention to NTSs during trauma team training may lead to sustained performance throughout trauma scenarios. Decision making and situation awareness skills are critical for both team leaders and teams and should be specifically addressed to improve performance. (J Surg 72:732-739.

UPDATE; RISK PATIENTS
AB Objective: Routine initiation beta-blocker medications before vascular surgery is controversial due to conflicting data. The purpose of this analysis was to determine whether prophylactic use of beta-blockers before major elective vascular surgery decreased postoperative cardiac events or mortality.
Methods: The Society for Vascular Surgery Vascular Quality Initiative (SVS-VQI) data set was used to perform a retrospective cohort analysis of infrainguinal lower extremity bypass (LEB), aortofemoral bypass (AFB), and open abdominal aortic aneurysm(AAA) repair patients. Chronic (>30 days preoperatively) beta-blocker patients were excluded, and comparisons were made between preoperative (0-30 day) and no beta-blocker groups. Patients were risk stratified using a novel prediction tool derived specifically from the SVS-VQI data set. Propensity-matched pairs and interprocedural specific risk stratification comparisons were performed. End points included in-hospital major adverse cardiac events (MACEs), including myocardial infarction (MI; defined as new ST or T wave electrocardiographic changes, troponin elevation, or documentation by echocardiogram or other imaging modality), dysrhythmia, and congestive heart failure, and 30-day mortality.
Results: The study analyzed 13,291 patients (LEB, 68% [n = 9047]; AFB, 11% [n = 1474]; and open AAA, 21% [n = 2770]); of these, 67.7% (n = 8999) were receiving beta-blockers at time of their index procedure. Specifically, 13.2% (n = 1753) were identified to have been started on a preoperative beta-blocker, 54.5% (n = 7426) were on chronic beta-blockers, and 32.3% (n = 4286) were on no preoperative beta-blockers. Among the three procedures, patients had significant demographic and comorbidity differences and thus were not combined. A 1: 1 propensity-matched pairs analysis (1459 pairs) revealed higher rates of postoperative MI with preoperative beta-blockers (preoperative beta-blocker relative risk, 1.65; 95% confidence interval, 1.02-2.68; P = .05 vs no beta-blocker), with no difference in dysrhythmia, congestive heart failure, or 30-day mortality. When stratified into low-risk, medium-risk, and high-risk groups within each procedure, all groups of preoperative beta-blocker patients had no difference or higher rates of MACEs and 30-day mortality, with the exception of high-risk open AAA patients, who had a lower rate of MI (odds ratio, 0.35; 95% confidence interval, 011-0.87; P = .04).
Conclusions: Exclusive of high-risk open AAA patients, preoperative beta-blockers did not decrease rates of MACEs or mortality after LEB, AFB, or open AAA. Importantly, exposure to prophylactic preoperative beta-blockers increased the rates of some adverse events in several subgroups. Given these data, the SVS-VQI cannot support routine initiation of preoperative beta-blockers before major elective vascular surgery in most patients.

AB The 2002 "unborn child ruling" resulted in State Children's Health Insurance Program (SCHIP) expansion for states to cover prenatal care for low-income women without health insurance. Foreign-born Latinas who do not qualify for Medicaid coverage theoretically should have benefited most from the policy ruling given their documented low rates of prenatal care utilization. This study compares prenatal care utilization and subsequent birth outcomes among foreign-born Latinas in six states that used the unborn child ruling to expand coverage to those in ten states that did not implement the expansion. This policy analysis examines cross-sectional pooled US natality data from the pre-enactment years (2000-2003) versus post-enactment years (2004-2007) to estimate the effect of the UCR on prenatal care utilization and birth outcome measures for foreign-born Latinas. Then using a difference-in-difference estimator, we assessed these differences across time for states that did or did not enact the unborn child ruling. Analyses were then replicated on a high-risk subset of the population (single foreign-born Latinas with lower levels of education). The SCHIP unborn child ruling policy expansion increased PNCU over time in the six enacting states. Foreign-born Latinas in expansion enacting states experienced increases in prenatal care utilization though only the high-risk subset were statistically significant. Birth outcomes did not change. The SCHIP unborn child ruling policy was associated with enhanced PNC for a subset of high-risk foreign-born Latinas.

AB Daytime and nighttime symptoms of posttraumatic stress disorder (PTSD) are common among combat veterans and military service members. However, there is a great deal of heterogeneity in how symptoms are expressed. Clarifying the heterogeneity of daytime and nighttime PTSD symptoms through exploratory clustering may generate hypotheses regarding ways to optimally match evidence-based treatments to PTSD symptom profiles. We used mixture modeling to reveal clusters based on 6 daytime and nighttime symptoms of 154 combat veterans with insomnia and varying levels of PTSD symptoms. Three clusters with increasing symptom severity were identified (n1 = 50, n2 = 70, n3 = 34). These results suggest that, among veterans with insomnia, PTSD symptoms tend to exist on a continuum of severity, rather than as a categorical PTSD diagnosis. Hypotheses regarding possible targeted treatment strategies for veterans within each identified cluster, as well as ways to generalize these methods to other groups within the military, are discussed.

AB Neutrophil elastase (NE) and cathepsin G (CG) contribute to intracellular microbial killing but, if left unchecked and released extracellularly, promote tissue damage. Conversely, mechanisms that constrain neutrophil serine protease activity protect against tissue damage but may have the untoward effect of disabling the microbial killing arsenal. The host elaborates thrombospondin-1 (TSP-1), a matricellular protein released during inflammation, but its role during neutrophil activation following microbial pathogen challenge remains uncertain. Mice deficient in TSP-1 (thbs1(-/-)) showed enhanced lung bacterial clearance, reduced splenic dissemination, and increased survival compared with wildtype (WT) controls during intrapulmonary Klebsiella pneumoniae infection. More effective pathogen containment was associated with reduced burden of inflammation in thbs1(-/-) mouse lungs compared with WT controls. Lung NE activity was increased in thbs1(-/-) mice following K. pneumoniae challenge, and thbs1(-/-) neutrophils showed enhanced intracellular microbial killing that was abrogated with recombinant TSP-1 administration or WT serum. Thbs1(-/-) neutrophils exhibited enhanced NE and CG enzymatic activity, and a peptide corresponding to amino-acid residues 793-801 within the type-III repeat domain of TSP-1 bridled neutrophil proteolytic function and microbial killing in vitro. Thus, TSP-1 restrains proteolytic action during neutrophilic inflammation elicited by K. pneumoniae, providing a mechanism that may regulate the microbial killing arsenal.

AB Stem cell technologies have facilitated the development of human cellular disease models that can be used to study pathogenesis and test therapeutic candidates. These models hold promise for complex neurological diseases such as Alzheimer's disease (AD), because existing animal models have been unable to fully recapitulate all aspects of pathology. We recently reported the characterization of a novel 3D culture system that exhibits key events in AD pathogenesis, including extracellular aggregation of amyloid-beta (A beta) and accumulation of hyperphosphorylated tau. Here we provide instructions for the generation and analysis of 3D human neural cell cultures, including the production of genetically modified human neural progenitor cells (hNPCNPCNPCs) with familial AD mutations, the differentiation of the hNPCNPCNPCs in a 3D matrix and the analysis of AD pathogenesis. The 3D culture generation takes 1-2 d. The aggregation of A beta is observed after 6 weeks of differentiation, followed by robust tau pathology after 10-14 weeks.

AB Objective: To examine effects of phacoemulsification on longer-term intraocular pressure (IOP) in patients with medically treated primary open-angle glaucoma (POAG; including normal-tension glaucoma), pseudoexfoliation glaucoma (PXG), or primary angle-closure glaucoma (PACG), without prior or concurrent incisional glaucoma surgery.
Methods: PubMed and Cochrane database searches, last conducted in December 2014, yielded 541 unique citations. Panel members reviewed titles and abstracts and selected 86 for further review. The panel reviewed these articles and identified 32 studies meeting the inclusion criteria, for which the panel methodologist assigned a level of evidence based on standardized grading adopted by the American Academy of Ophthalmology. One, 15, and 16 studies were rated as providing level I, II, and III evidence, respectively.
Results: All follow-up, IOP, and medication data listed are weighted means. In general, the studies reported on patients using few glaucoma medications (1.5-1.9 before surgery among the different diagnoses). For POAG, 9 studies (total, 461 patients; follow-up, 17 months) showed that phacoemulsification reduced IOP by 13% and glaucoma medications by 12%. For PXG, 5 studies (total, 132 patients; follow-up, 34 months) showed phacoemulsification reduced IOP by 20% and glaucoma medications by 35%. For chronic PACG, 12 studies (total, 495 patients; follow-up, 16 months) showed phacoemulsification reduced IOP by 30% and glaucoma medications by 58%. Patients with acute PACG (4 studies; total, 119 patients; follow-up, 24 months) had a 71% reduction from presenting IOP and rarely required long-term glaucoma medications when phacoemulsification was performed soon after medical reduction of IOP. Trabeculectomy after phacoemulsification was uncommon; the median rate reported within 6 to 24 months of follow-up in patients with controlled POAG, PXG, or PACG was 0% and was 7% in patients with uncontrolled chronic PACG.
Conclusions: Phacoemulsification typically results in small, moderate, and marked reductions of IOP and medications for patients with POAG, PXG, and PACG, respectively, and using 1 to 2 medications before surgery. Trabeculectomy within 6 to 24 months after phacoemulsification is rare in such patients. However, reports on its effects in eyes with advanced disease or poor IOP control before surgery are few, particularly for POAG and PXG. (C) 2015 by the American Academy of Ophthalmology.

AB Purpose: To describe a syndrome of hemorrhagic occlusive retinal vasculitis (HORV) that developed after seemingly uncomplicated cataract surgery.
Design: Retrospective case series.
Subjects: Eleven eyes of 6 patients from 6 different institutions.
Methods: Cases were identified after discussion among retina specialists. The findings on presentation, clinical course, and outcome of a series of 7 eyes of 4 patients were compared with a previous report of 4 eyes of 2 patients, and data from both series were combined for a comprehensive analysis.
Main Outcome Measures: Historical data, examination findings, imaging results, systemic evaluation findings, treatment regimens, and visual outcomes.
Results: Eleven eyes of 6 patients underwent otherwise uncomplicated cataract surgery, receiving viscoelastic and prophylactic intracameral vancomycin during the procedure. Despite good initial vision on postoperative day 1, between 1 to 14 days after surgery, all eyes demonstrated painless vision loss resulting from HORV. Extensive ocular and systemic evaluations were unrevealing in all patients. All patients were treated with aggressive systemic and topical corticosteroids. Additional treatments included systemic antiviral medication in 4 patients, intravitreal antibiotics in 4 eyes, and pars plana vitrectomy in 4 eyes. Skin testing for vancomycin sensitivity showed negative results in 3 patients and was not performed in the others. Neovascular glaucoma developed in 7 eyes, and all eyes received intravitreal anti-vascular endothelial growth factor (VEGF) injection, panretinal photocoagulation, or both for retinal ischemia. Final visual acuity was less than 20/100 in 8 of 11 eyes.
Conclusions: Postoperative HORV is an exceedingly rare and potentially devastating condition that can occur after otherwise uncomplicated cataract surgery. Although the precise cause remains unknown, this disease may represent a delayed immune reaction similar to vancomycin-induced leukocytoclastic vasculitis. Despite treatment with high-dose corticosteroids, antiviral medication, and early vitrectomy in many patients, visual outcomes typically were poor in this series. Early intervention with intravitreal anti-VEGF medication and panretinal photocoagulation may help to prevent additional vision loss resulting from neovascular glaucoma.

SO OPHTHALMOLOGY

DT Article
ID EPIDEMIOLOGY; VALIDATION; DIAGNOSIS
AB Purpose: The aim of this study was to compare patient-reported symptoms of dry eye disease (DED) as assessed by the Ocular Surface Disease Index (OSDI), a 12-item symptom frequency-based questionnaire, and the Symptom Assessment iN Dry Eye (SANDE), a 2-item frequency-and severity-based visual analog scale.
Design: Clinic-based evaluation of a diagnostic test.
Participants: A total of 114 patients with DED.
Methods: Patients were administered the OSDI and SANDE questionnaires at baseline and follow-up visits to evaluate DED-related symptoms. The correlations between both questionnaires' scores were evaluated using the Spearman coefficient, and their clinical differences were assessed using Bland-Altman analysis.
Main Outcome Measures: Baseline and follow-up visit OSDI and SANDE dry eye symptom scores.
Results: At the baseline visit, the OSDI and SANDE questionnaire scores were significantly correlated (R = 0.64; P < 0.001). Moreover, a significant correlation was found between changes in the OSDI and SANDE scores from baseline to follow-up visits (R = 0.47; P < 0.001). A Bland-Altman analysis, after score normalization, revealed a difference (bias) of less than 2 centesimal units between the scores of the 2 questionnaires.
Conclusions: Data collected from the SANDE questionnaire showed a significant correlation and negligible score differences with those from the OSDI, suggesting that the SANDE visual analog scale-based questionnaire has the potential to provide clinicians with a short, quick, and reliable measure for DED symptoms.

AB Learning and memory for extinction of conditioned fear is a basic mammalian mechanism for regulating negative emotion. Sleep promotes both the consolidation of memory and the regulation of emotion. Sleep can influence consolidation and modification of memories associated with both fear and its extinction. After brief overviews of the behavior and neural circuitry associated with fear conditioning, extinction learning, and extinction memory in the rodent and human, interactions of sleep with these processes will be examined. Animal and human studies suggest that sleep can serve to consolidate both fear and extinction memory. In humans, sleep also promotes generalization of extinction memory. Time-of-day effects on extinction learning and generalization are also seen. Rapid eye movement (REM) may be a sleep stage of particular importance for the consolidation of both fear and extinction memory as evidenced by selective REM deprivation experiments. REM sleep is accompanied by selective activation of the same limbic structures implicated in the learning and memory of fear and extinction. Preliminary evidence also suggests extinction learning can take place during slow wave sleep. Study of low-level processes such as conditioning, extinction, and habituation may allow sleep effects on emotional memory to be identified and inform study of sleep's effects on more complex, emotionally salient declarative memories. Anxiety disorders are marked by impairments of both sleep and extinction memory. Improving sleep quality may ameliorate anxiety disorders by strengthening naturally acquired extinction. Strategically timed sleep may be used to enhance treatment of anxiety by strengthening therapeutic extinction learned via exposure therapy.

AB Imaging of acute neurologic disease in the emergency department can be challenging because of the wide range of possible causes and the overlapping imaging appearance of many of these entities on nonenhanced computed tomography (CT). The key to formulating a succinct, pertinent differential diagnosis includes characterizing the pattern of abnormalities on CT and identifying key features that suggest a particular diagnosis.

AB Background Stroke is common and costly, annually depriving the lives and well-being of 800,000 Americans. Despite demonstrated efficacy in clinical trials, questions remain about the safety and clinical effectiveness of various treatment options given patient characteristics, conditions, preferences, and their desired outcomes.
Methods and results The Patient-Centered Research Into Outcomes Stroke Patients Prefer and Effectiveness Research (PROSPER) is a Patient-Centered Outcomes Research Institute-sponsored project designed to help patients, physicians, and other stakeholders make informed decisions regarding stroke care and improve outcomes through patient-centered comparative effectiveness research. The primary outcomes identified and prioritized by stroke patients are "home time" (time spent alive and outside a hospital) and major adverse cardiovascular events. With inputs from stroke patients themselves, a series of comparative safety and effectiveness analyses will be performed across 3 prioritized therapeutic areas identified as important by stroke survivors: oral anticoagulants, statin therapy, and antidepressants. We obtained data from Get With the Guidelines-Stroke linked with Medicare claims and follow-up telephone interviews. Our combined retrospective and prospective research strategy allows the evaluation of the safety and effectiveness of various treatment options and patient-centered longitudinal outcomes. To ensure the rapid translation of findings into clinical practice, results will be disseminated to stroke survivors, caregivers, and health care providers through traditional and social media, including an online decision aid tool.
Conclusions PROSPER is a patient-centered outcome research study guided by patients, caregivers, and the broader health care community. By addressing knowledge gaps in treatment uncertainties through comparative effectiveness research, PROSPER has the potential to improve decision making in stroke care and patient outcomes reflecting individual patient preferences, needs, and values.

UNITED-STATES; QUALITY; OUTCOMES; EFFICACY; RISK; INTENSITY; ALGORITHM
AB Background Time in therapeutic range (TTR) of international normalized ratio (INR) of 2.0 to 3.0 is important for the safety and effectiveness of warfarin anticoagulation. There are few data on TTR among patients with atrial fibrillation (AF) in community-based clinical practice.
Methods Using the US Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF), we examined TTR (using a modified Rosendaal method) among 5,210 patients with AF on warfarin and treated at 155 sites. Patients were grouped into quartiles based on TTR data. Multivariable logistic regression modeling with generalized estimating equations was used to determine patient and provider factors associated with the lowest (worst) TTR.
Results Overall, 59% of the measured INR values were between 2.0 and 3.0, with an overall mean and median TTR of 65%+/- 20% and 68% (interquartile range [IQR] 53%-79%). The median times below and above the therapeutic range were 17% (IQR 8%-29%) and 10% (IQR 3%-19%), respectively. Patients with renal dysfunction, advanced heart failure, frailty, prior valve surgery, and higher risk for bleeding (ATRIA score) or stroke (CHA2DS2-VASc score) had significantly lower TTR (P < .0001 for all). Patients treated at anticoagulation clinics had only slightly higher median TTR (69%) than those not (66%) (P < .0001).
Conclusions Among patients with AF in US clinical practices, TTR on warfarin is suboptimal, and those at highest predicted risks for stroke and bleeding were least likely to be in therapeutic range.

AB Objectives: At the 2013 Society for Hematopathology/European Association for Hematopathology Workshop, 36 cases were submitted to the session that covered acute erythroid leukemia (AEL), acute megakaryoblastic leukemia (AMKL), and reactive mimics.
Methods: Cases were reviewed by the session chairs and workshop panel to reach a consensus diagnosis.
Results: For acute erythroleukemia, erythroid/myeloid type, discussion acknowledged overlapping features between AEL and myelodysplastic syndromes. Cases submitted as pure erythroid leukemia had distinctive morphology and immunophenotype, complex karyotypes, and aggressive clinical behavior, illustrating certain diagnostic features not currently captured by the current World Health Organization (WHO) definition. In Down syndrome, there were striking similarities between transient abnormal myelopoiesis and AMKL. Most cases of AMKL in adults would be classified as acute myeloid leukemia with myelodysplasia-related changes according to the WHO classification, but this approach deemphasizes their unique clinical, morphologic, and immunophenotypic features.
Conclusions: The broad spectrum of cases illustrated the difficulties and complex issues involved in establishing a diagnosis of these entities and the need for better disease definitions.

ID PLASMODIUM-FALCIPARUM MALARIA; CLINICAL-MANIFESTATIONS; UNITED-STATES;
TRANSMISSION; COUNTS
AB Objectives: Anemia and thrombocytopenia are expected hematologic abnormalities in patients with acute babesiosis, whereas neutropenia (defined as an absolute neutrophil count of <= 1,800 neutrophils/mu L for adults and <1,200 neutrophils/mu L for infants) is not usually considered a feature of this infection. We studied the frequency with which neutropenia occurs in congenital and adult cases of babesiosis.
Methods: The frequency of neutropenia in cases of congenital babesiosis was determined based on a literature review and on the findings in an unreported case. The frequency of neutropenia in adult patients was assessed based on a review of the medical records of 51 patients who were diagnosed with babesiosis between 2010 and 2013 at two medical centers in the Northeastern United States.
Results: Four (80%; 95% confidence interval [CI], 36%-98%) of five infants with congenital babesiosis whose neutrophil count was reported were neutropenic. Among 51 adult cases with babesiosis, 11 (22%; 95% CI, 12%-35%) were neutropenic on clinical presentation, and seven others developed neutropenia over the next 1 to 21 days. Thus, a total of 18 (35%; 95% CI, 24%-49%) of the adult patients with babesiosis had neutropenia.
Conclusions: Neutropenia appears to be a common finding in infants with congenital babesiosis and is also observed not infrequently in adults with this infection.

TI Feasibility of "rapid" magnetic resonance imaging in pediatric acute
head injury
SO AMERICAN JOURNAL OF EMERGENCY MEDICINE
LA English
DT Article
ID EMERGENCY-DEPARTMENT; COMPUTED-TOMOGRAPHY; RADIATION-EXPOSURE;
HYDROCEPHALUS; CT
AB Objective: The objective was to determine the feasibility of "rapid" magnetic resonance imaging (rMRI) versus noncontrast computed tomography (NCCT) for pediatric patients with possible traumatic brain injury and to compare the populations receiving imaging in an urban tertiary care emergency department ED.
Methods: We retrospectively reviewed the electronic medical records of ED patients younger than 19 years with possible traumatic brain injury over 4 years who received an rMRI and then age-matched with NCCT patients. Data collection and analysis included demographic and clinical variables, ED length of stay (LOS), and follow-up outcomes.
Results: The final cohort had 45 rMRIs and 45 NCCTs. The mean age was 2.7 years, 63% were male, and 65% sustained a fall. Age, sex, and injury mechanism were similar. Time parameters were longer for rMRI patients: ED arrival to completion of imaging (172 vs 93 minutes, P < .001) and ED LOS (266 vs 225 minutes, P = .008). The NCCT group had higher-acuity patients with higher pediatric intensive care unit admission rates (33% vs 7%, P = .002). No patients returned to the ED within 72 hours. Follow-up was available on 78% patients. No clinically significant intracranial injuries were missed.
Conclusions: Rapid MRI may be a viable imaging modality for moderate-risk pediatric head injury. Although rMRI took longer to obtain during this pilot study, scan time was only 3 to 4 minutes; and LOS was only 41 minutes longer. Further integration of rMRI in patient care should decrease time variation. Future study of rMRI reliability and satisfaction is needed. (C) 2015 Elsevier Inc. All rights reserved.

AB Although there have been mounting concerns over the decline in applicants to nephrology training programs, strategies to entice students and trainees to pursue a career in nephrology are lacking. Furthermore, the complex factors that contribute to career decisions and the lag between a positive interaction and a decision to pursue nephrology make such strategies difficult to assess. Nevertheless, it is still important to continue efforts to mentor and inspire. This article offers 10 strategies to help nephrologists share passion for nephrology in the clinical arena.

AB Calciphylaxis is a rare but devastating condition that has continued to challenge the medical community since its early descriptions in the scientific literature many decades ago. It is predominantly seen in patients with chronic kidney failure treated with dialysis (uremic calciphylaxis) but is also described in patients with earlier stages of chronic kidney disease and with normal kidney function. In this review, we discuss the available medical literature regarding risk factors, diagnosis, and treatment of both uremic and nonuremic calciphylaxis. High-quality evidence for the evaluation and management of calciphylaxis is lacking at this time due to its rare incidence and poorly understood pathogenesis and the relative paucity of collaborative research efforts. We hereby provide a summary of recommendations developed by a multidisciplinary team for patients with calciphylaxis. (C) 2015 by the National Kidney Foundation, Inc.

AB OBJECTIVE: The purpose of this study was to review consecutive cases of angiotensin-converting enzyme (ACE) inhibitor angioedema admitted to an intensive care unit.
METHODS: Fifty subjects with ACE-inhibitor angioedema admitted from 1998-2011 were reviewed.
RESULTS: All 50 subjects were men, 62.8 +/- 8.4 years of age, 76% African Americans. Fifteen (30%) required ventilatory support and 2 (4%) required tracheostomy. Over half (56%) had taken ACE inhibitors for over a year. Logistic regression identified dyspnea and tongue involvement with the need for ventilatory support (P < .01). Hypercapnia (PaCO2 +/- 45.2 +/- 6.7; P < 0.046) also identified patients needing ventilatory support.
CONCLUSIONS: Ventilatory support was provided for about one-third of those with ACE inhibitorassociated angioedema. Angioedema can occur even after extended use. Dyspnea and tongue involvement identified patients requiring ventilatory support. Published by Elsevier Inc.

AB BACKGROUND: Although various studies have documented increased life-sustaining treatments among racial minorities in medical patients, whether similar disparities exist in surgical patients is unknown.
METHODS: A retrospective cohort study using the Nationwide Inpatient Sample (2006 to 2011) examining patients older than 39 years who died after elective colectomy was performed. Primary predictor variable was race, and main outcome was the use of life-sustaining treatment.
RESULTS: In univariate analysis, significant differences existed in use of cardiopulmonary resuscitation (CPR; black, 35.9%; Hispanic, 29.0%; other, 24.5%; white, 11.7%; P = .002) and reintubation (Hispanic, 75.0%; other, 69.0%; black, 52.3%; white, 45.2%; P = .01). In multivariate analysis, black (odds ratio [OR], 3.67; P = .01) and Hispanic (OR, 4.21; P = .03) patients were more likely to have undergone CPR, and Hispanic patients (OR, 4.24; P = .01) were more likely to have been reintubated (reference: white).
CONCLUSIONS: Blacks and Hispanics had increased odds of experiencing CPR, and Hispanics were more likely to have been reintubated before death after a major elective operation. These variations may imply worse quality of death and increased associated costs. (C) 2015 Elsevier Inc. All rights reserved.

CONSERVATION; IRRADIATION
AB BACKGROUND: In breast conserving surgery, the concordance between lumpectomy margin (LM) status and the status of the corresponding lumpectomy cavity remains uncertain.
METHODS: We analyzed pathology reports of lumpectomies from 2004 to 2006. We included those which contained both ink-directed LM and complete (>= 4) separate corresponding shaved cavity margins (SCMs). SCM pathology was used as a surrogate for lumpectomy cavity status, to determine the predictive value of LM for residual disease.
RESULTS: Pathology from 1,201 pairs of LM and SCM from 242 patients was compared. LM status predicted corresponding lumpectomy cavity status with 50.9% sensitivity, 69.5% specificity, 35% positive predictive value, and 81.4% negative predictive value, giving an overall accuracy of 64.9%.
CONCLUSIONS: Oriented LMs are not reliable for predicting lumpectomy cavity status, and therefore not reliable for directing re-excision. Taking complete, oriented SCMs at the time of lumpectomy may improve accuracy compared with traditional LM assessment. (C) 2015 Elsevier Inc. All rights reserved.

AB Links between the human microbiome and the innate and adaptive immune systems and their impact on autoimmune and inflammatory diseases are only beginning to be recognized. Characterization of the complex human microbial community is facilitated by culture-independent nucleic acid sequencing tools and bioinformatics systems. Specific organisms and microbial antigens are linked with initiation of innate immune responses that, depending on the context, may be associated with tolerogenic or effector immune responses. Further complexity is introduced by preclinical data that demonstrate the impacts of dietary manipulation on the prevention of genetically determined, systemic autoimmune disorders and on gastrointestinal microbiota. Investigation of interactions of complex microbial populations with the human immune system may provide new targets for clinical management in allotransplantation.

AB Cytomegalovirus accelerates transplant vascular sclerosis (TVS) and chronic rejection (CR) in solid organ transplants; however, the mechanisms involved are unclear. We determined the efficacy of a CMV vaccine in preventing CMV-accelerated rat cardiac allograft rejection in naive recipients of CMV+ donor hearts. F344 donor rats were infected with RCMV 5 days prior to heterotopic cardiac transplantation into CMV-naive or H2O2-inactivated RCMV-vaccinated Lewis recipients. Recipients of RCMV-infected donor hearts rejected at POD59, whereas vaccinated recipients exhibited a significantly prolonged time to rejection-POD97, similar to recipients of uninfected donor hearts (POD108). Although all of the donor hearts were preinfected, the vaccinated recipients had lower graft and PBMC viral loads at POD 7 compared to unvaccinated controls. Adoptive T cell and passive antibody transfers from vaccinated Lewis rats into naive recipients demonstrate that both T-cell and B-cell arms of the adaptive immune response provide protection against CMV-accelerated rejection. Similar findings were obtained when testing three different adjuvants in passive transfer experiments. We have determined that the timing of the vaccine prior to transplantation and the specific adjuvant play critical roles in mediating anti-viral responses and promoting graft survival. CMV vaccination prior to transplantation may effectively increase graft survival.

SURVIVAL; FAILURE; CANCER
AB Geographic variability in access to care is a persistent challenge in transplantation. Little is known about how patients with end-stage liver disease are chosen for referral, evaluation and listing. Utilizing death certificate data from the Centers for Disease Control and Prevention from 2002 to 2009, estimated liver demand (ELD) was measured by aggregating annual deaths from liver disease and liver transplants performed in each donor service area (DSA). In DSAs with higher ELD, more patients per capita were listed for transplantation (p<0.001). In addition, listing rates per ELD varied fivefold across DSAs, with more patients per ELD being transplanted in DSAs with higher listing rates (p<0.001). After adjusting for liver donor risk index and MELD at transplant, there was no association between listing rate and posttransplant survival (HR 1.002, p=0.77). In addition, DSAs with lower listing rates were more likely to export organs (p<0.001) of lower liver donor risk index (p<0.001). Listing sicker patients was associated with increased access to the waitlist and transplantation and more efficient organ utilization, but had minimal effect on posttransplant outcomes after adjusting for the resulting organ shortage.

AB Background Diuretic-induced gout might occur only among those with a genetic predisposition to hyperuricaemia, as suggested by a recent study with 108 self-reported gout cases.
Methods We examined the role of urate genes on the risk of diuretic-induced incident gout in 6850 women from the Nurses' Health Study (NHS) and in 4223 men from the Health Professionals Follow-up Study (HPFS). Two published genetic risk scores (GRSs) were calculated using urate-associated single-nucleotide polymorphisms for 8 (GRS8) and 29 genes (GRS29).
Results Our analyses included 727 and 354 confirmed incident gout cases in HPFS and NHS, respectively. The multivariate relative risk (RR) for diuretic use was 2.20 and 1.69 among those with GRS8 < and >= the median (p for interaction=0.27). The corresponding RRs using GRS29 were 2.19 and 1.88 (p for interaction=0.40). The lack of interaction persisted in NHS (all p values >0.20) and in our analyses limited to those with hypertension in both cohorts. SLC22A11 (OAT4) showed a significant interaction only among women but in the opposite direction to the recent study.
Conclusions In these large prospective studies, individuals with a genetic predisposition for hyperuricaemia are not at a higher risk of developing diuretic-induced gout than those without.

TI Cartilage-specific deletion of mTOR upregulates autophagy and protects

AB Objectives Mammalian target of rapamycin (mTOR) (a serine/threonine protein kinase) is a major repressor of autophagy, a cell survival mechanism. The specific in vivo mechanism of mTOR signalling in OA pathophysiology is not fully characterised. We determined the expression of mTOR and known autophagy genes in human OA cartilage as well as mouse and dog models of experimental OA. We created cartilage-specific mTOR knockout (KO) mice to determine the specific role of mTOR in OA pathophysiology and autophagy signalling in vivo.
Methods Inducible cartilage-specific mTOR KO mice were generated and subjected to mouse model of OA. Human OA chondrocytes were treated with rapamycin and transfected with Unc-51-like kinase 1 (ULK1) siRNA to determine mTOR signalling.
Results mTOR is overexpressed in human OA cartilage as well as mouse and dog experimental OA. Upregulation of mTOR expression co-relates with increased chondrocyte apoptosis and reduced expression of key autophagy genes during OA. Subsequently, we show for the first time that cartilage-specific ablation of mTOR results in increased autophagy signalling and a significant protection from destabilisation of medial meniscus (DMM)-induced OA associated with a significant reduction in the articular cartilage degradation, apoptosis and synovial fibrosis. Furthermore, we show that regulation of ULK1/adenosine monophosphate-activated protein kinase (AMPK) signalling pathway by mTOR may in part be responsible for regulating autophagy signalling and the balance between catabolic and anabolic factors in the articular cartilage.
Conclusions This study provides a direct evidence of the role of mTOR and its downstream modulation of autophagy in articular cartilage homeostasis.

AB This report examined the most frequently reported bothersome tics among individuals with chronic tic disorders and evaluated the improvement and remission of tics and their associated characteristics. Youths and adults (N = 240) were randomly assigned to receive the comprehensive behavioral intervention for tics (CBIT) or psychoeducation and supportive therapy (PST). At baseline, motor tics and tics with an urge were rated as more bothersome relative to vocal tics and tics without premonitory urges. The five most common bothersome tics included eye blinking, head jerks, sniffing, throat clearing, and other complex motor tics. While CBIT outperformed PST across tic type and urge presence, tics preceded by premonitory urges at baseline had higher severity at posttreatment across treatment condition. Six individual tic types had lower severity at posttreatment following CBIT relative to PST. Baseline urge presence was associated with tic remission for CBIT but not PST. Specific bothersome tics were more likely to remit with CBIT relative to PST. Findings suggest that individual tics respond and remit differently to CBIT relative to PST, with implications highlighting the negative reinforcement hypothesis in tic symptom maintenance.

AB Objectives To define the target domains of culture-improvement interventions, to assess the impact of these interventions on surgical culture and to determine whether culture improvements lead to better patient outcomes and improved healthcare efficiency.
Background Healthcare systems are investing considerable resources in improving workplace culture. It remains unclear whether these interventions, when aimed at surgical care, are successful and whether they are associated with changes in patient outcomes.
Methods PubMed, Cochrane, Web of Science and Scopus databases were searched from January 1980 to January 2015. We included studies on interventions that aimed to improve surgical culture, defined as the interpersonal, social and organisational factors that affect the healthcare environment and patient care. The quality of studies was assessed using an adapted tool to focus the review on higher-quality studies. Due to study heterogeneity, findings were narratively reviewed.
Findings The 47 studies meeting inclusion criteria (4 randomised trials and 10 moderate-quality observational studies) reported on interventions that targeted three domains of culture: teamwork (n=28), communication (n=26) and safety climate (n=19); several targeted more than one domain. All moderate-quality studies showed improvements in at least one of these domains. Two studies also demonstrated improvements in patient outcomes, such as reduced postoperative complications and even reduced postoperative mortality (absolute risk reduction 1.7%). Two studies reported improvements in healthcare efficiency, including fewer operating room delays. These findings were supported by similar results from low-quality studies.
Conclusions The literature provides promising evidence for various strategies to improve surgical culture, although these approaches differ in terms of the interventions employed as well as the techniques used to measure culture. Nevertheless, culture improvement appears to be associated with other positive effects, including better patient outcomes and enhanced healthcare efficiency.

AB OBJECTIVE: Uterine caicinosarcoma (CS) is an aggressive malignancy and the optimal adjuvant treatment is not well-established. We report outcomes with vaginal brachytherapy (VB) for women with early-stage CS.
METHODS AND MATERIALS: A multi-institutional retrospective study of Stage CS treated with hysterectomy, surgical staging, and adjuvant high-dose-rate VB without external-beam pelvic radiotherapy was performed. Rates of vaginal control, pelvic control, locoregional control, disease-free survival, and overall survival were determined using the Kaplan-Meier method.
RESULTS: 33 patients were identified. Prescribed VB dose was 21 Gy in three fractions (n = 15 [45%]) or 24 Gy in six fractions (n = 18 [55%]). Eighteen patients (55%) received chemotherapy. Median followup was 2.0 years. Twenty-seven patients (82%) underwent pelvic lymphadenectomy, 5 (15%) had nodal sampling, and 1 (3%) had no lymph node assessment. Relapse occurred in 11 patients (33%), all of whom had lymph node evaluation. Locoregional relapse was a component of failure in 6 patients (18%), of whom 3 (9%) failed in the pelvis alone. Three patients (9%) had simultaneous distant and locoregional relapse (two vaginal, one pelvic). Five additional patients (15%) had distant relapse. Six of the 11 patients (55%) with disease recurrence received chemotherapy. Two-year vaginal control and pelvic control were 94% and 87%. Two-year locoregional control, disease-free survival, and overall survival were 81%, 66%, and 79%.
CONCLUSIONS: Despite having early-stage disease and treatment with VB, patients in this series had relatively high rates of local and distant relapse. Patients who undergo lymphadenectomy and VB remain at risk for relapse. Novel treatment strategies are needed. (C) 2015 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

AB PURPOSE: To increase intraprocedural efficiency in the use of clinical resources and to decrease planning time for cervical cancer brachytherapy treatments through redesign of the procedure's process map.
METHODS AND MATERIALS: A multidisciplinary team identified all tasks and associated resources involved in cervical cancer brachytherapy in our institution and arranged them in a process map. A redesign of the treatment planning component of the process map was conducted with the goal of minimizing planning time. Planning time was measured on 20 consecutive insertions, of which 10 were performed with standard procedures and 10 with the redesigned process map, and results were compared. Statistical significance (p < 0.05) was measured with a two-tailed t test.
RESULTS: Twelve tasks involved in cervical cancer brachytherapy treatments were identified. The process map showed that in standard procedures, the treatment planning tasks were performed sequentially. The process map was redesigned to specify that contouring and some planning tasks are performed concomitantly. Some quality assurance tasks were reorganized to minimize adverse effects of a possible error on procedure time. Test dry runs followed by live implementation confirmed the applicability of the new process map to clinical conditions. A 29% reduction in planning time (p < 0.01) was observed with the introduction of the redesigned process map.
CONCLUSIONS: A process map for cervical cancer brachytherapy was generated. The treatment planning component of the process map was redesigned, resulting in a 29% decrease in planning time and a streamlining of the quality assurance process.

AB PURPOSE: The relative use of brachytherapy (BT) for prostate cancer has declined in recent years. In this setting, we sought to determine whether the case mix of BT monotherapy treated men has changed over time in terms of risk group composition.
METHODS AND MATERIALS: The Surveillance, Epidemiology, and End Results database was used to identify 30,939 patients diagnosed with prostate adenocarcinoma between 2004 and 2011 who received BT monotherapy. The case mix of BT monotherapy patients was calculated by patient risk group and year of diagnosis.
RESULTS: Between 2004 and 2011, the use of BT monotherapy declined overall. The relative percentage of men undergoing BT with low-risk disease declined by 4.5%, whereas the relative percentage of patients with intermediate-risk disease increased by 4.7%. Non-white patients and those from poorer counties did not show shifts in the risk group makeup of BT monotherapy patients, whereas white patients and those from wealthier counties did.
CONCLUSIONS: Although fewer patients with prostate cancer are undergoing BT monotherapy, men with intermediate-risk disease comprised a significantly larger portion of the BT case mix in 2011 compared with 2004. Future research efforts by brachytherapists should be directed toward improving BT technique, optimizing radiation doses, and obtaining long-term followup data for patients with intermediate-risk prostate cancer.

AB Although engagement of medial prefrontal cortex (MPFC) underlies self-referencing of information for younger and older adults, the region has not consistently been implicated across age groups for the encoding of self-referenced information. We sought to determine whether making judgments about others as well as the self influenced findings in the previous study. During an fMRI session, younger and older adults encoded adjectives using only a self-reference task. For items later remembered compared to those later forgotten, both age groups robustly recruited medial prefrontal cortex, indicating common neural regions support encoding across younger and older adults when participants make only self-reference judgments. Focal age differences emerged in regions related to emotional processing and cognitive control, though these differences are more limited than in tasks in which judgments also are made about others. We conclude that making judgments about another person differently affects the ways that younger and older adults make judgments about the self, with results of a follow-up behavioral study supporting this interpretation.

AB BACKGROUNDThe current study was conducted to assess acute and late adverse events (AEs), overall survival (OS), pelvic failure, regional failure, distant failure, and disease-free survival in a prospective phase 2 clinical trial of bevacizumab and pelvic intensity-modulated radiotherapy (IMRT) with chemotherapy in patients with high-risk endometrial cancer.
METHODSPatients underwent a hysterectomy and lymph node removal, and had 1 of the following high-risk factors: grade 3 carcinoma with >50% myometrial invasion, grade 2 or 3 disease with any cervical stromal invasion, or known extrauterine extension confined to the pelvis. Treatment included pelvic IMRT and concurrent cisplatin on days 1 and 29 of radiation and bevacizumab (at a dose of 5 mg/kg on days 1, 15, and 29 of radiation) followed by adjuvant carboplatin and paclitaxel for 4 cycles. The primary endpoint was grade 3 AEs occurring within the first 90 days (toxicity was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]).
RESULTSA total of 34 patients were accrued from November 2009 through December 2011, 30 of whom were eligible and received study treatment. Seven of 30 patients (23.3%; 1-sided 95% confidence interval, 10.6%-36.0%) developed grade 3 treatment-related nonhematologic toxicities within 90 days; an additional 6 patients experienced grade 3 toxicities between 90 and 365 days after treatment. The 2-year OS rate was 96.7% and the disease-free survival rate was 79.1%. No patient developed a within-field pelvic failure and no patients with International Federation of Gynecology and Obstetrics stage I to IIIA disease developed disease recurrence after a median follow-up of 26 months.
CONCLUSIONSPostoperative bevacizumab added to chemotherapy and pelvic IMRT appears to be well tolerated and results in high OS rates at 2 years for patients with high-risk endometrial carcinoma. Cancer 2015;121:2156-2163. (c) 2015 American Cancer Society.

AB BACKGROUNDWaldenstrom macroglobulinemia (WM) is an indolent malignancy that predominantly affects older individuals who are at risk for secondary malignancies (SMs). The objective of this study was to characterize the incidence of SMs after a diagnosis of WM with the Surveillance, Epidemiology, and End Results (SEER) database.
METHODSWith SEER-13 data (1992-2011), standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated for the rates of solid and hematologic SMs in WM patients versus the general population. The analysis was stratified by age, sex, race, year of diagnosis, and latency from the WM diagnosis.
RESULTSAmong 4676 patients with WM, 681 SMs were recorded. The overall SIR was 1.49 (95% CI, 1.38-1.61), and the median time to an SM was 3.7 years. The cumulative incidence of SMs was 10% at 5 years and 16% at 10 years. The risk was significantly increased for cancers of the lungs, urinary tract, and thyroid; melanoma; aggressive lymphoma; and acute leukemia. The SIR for SMs in patients with WM was increased, regardless of age, sex, race, or year of diagnosis.
CONCLUSIONSPatients with WM had a 49% higher risk of SMs than the general population. The selectively increased risk for hematologic SMs and certain solid SMs may be associated with transformation, therapy, and immune dysregulation. Cancer 2015;121:2230-2236. (c) 2015 American Cancer Society.

AB BACKGROUNDPreclinical evidence supports the clinical investigation of inhibitors to the insulin-like growth factor receptor (IGFR) and the epidermal growth factor receptor (EGFR) either alone or in combination as treatment for patients with non-small cell lung cancer (NSCLC).
METHODSPatients with chemotherapy-naive, advanced NSCLC who had an Eastern Cooperative Oncology Group performance status of 0 or 1 were eligible. Patients were randomized to receive carboplatin intravenously at an area under the plasma drug concentration-time curve of 6.0 plus paclitaxel 200 mg/m(2) intravenously on day 1 every 3 weeks combined with either intravenous cetuximab weekly (arm A), intravenous cixutumumab every 2 weeks (arm B), or both (arm C). Patients who had nonprogessing disease after 12 weeks of therapy were permitted to continue on maintenance antibody therapy until they developed progressive disease. The primary endpoint was progression-free survival (PFS). The study design required 180 eligible patients and had 88% power to detect a 60% increase in median PFS for either comparison (arm A vs arm C or arm B vs arm C) using the log-rank test.
RESULTSFrom September 2009 to December 2010, 140 patients were accrued. The study was closed to accrual early because of an excessive number of grade 5 events reported on arms A and C. Thirteen patients died during treatment (6 patients on arm A, 2 patients on arm B, and 5 patients on arm C), including 9 within approximately 1 month of starting therapy. The estimated median PFS for arms A, B, and C were similar at 3.4 months, 4.2 months, and 4 months, respectively.
CONCLUSIONSOn the basis of the apparent lack of efficacy and excessive premature deaths, the current results do not support the continued investigation of carboplatin, paclitaxel, and cixutumumab either alone or in combination with cetuximab for patients with advanced NSCLC.

DT Review
ID LYMPH-NODE BIOPSY; PROGNOSTIC-FACTORS; MANAGEMENT; EXPRESSION
AB Extramammary Paget disease (EMPD) is an uncommon intraepithelial adenocarcinoma that involves body sites with apocrine glands such as the genital, perineal and perianal regions. Risk stratification and treatment planning for EMPD can be challenging. This review presents important prognostic information in EMPD to assist physicians with risk stratification of patients with EMPD. The best-understood prognostic factors are depth of invasion and involvement of extracutaneous sites. Tumours that invade into the reticular dermis or have a depth of >1mm are associated with poorer prognosis. Additionally, tumours spreading outside the skin into lymph nodes or other tissues are higher risk. There is an emerging understanding of the importance of tumour genetics in risk stratification, and we review the data on Ki-67, cyclin D1, Mucin 5AC and E-cadherin. There is less evidence supporting the importance of lesion site and patient age in risk stratification. This succinct review will be helpful in clinical practice and in EMPD research.

AB Background: Carpal tunnel syndrome is a common and costly peripheral neuropathy. Occupations requiring repetitive, forceful motions of the hand and wrist may play a role in the development of carpal tunnel syndrome. Computer keyboarding is one such task, and has been associated with upper-extremity musculoskeletal disorder development. The purpose of this study was to determine whether continuous keyboarding can cause acute changes in the median nerve and whether these changes correlate with wrist biomechanics during keyboarding.
Methods: A convenience sample of 37 healthy individuals performed a 60-minute typing task. Ultrasound images were collected at baseline, after 30 and 60 min of typing, then after 30 min of rest. Kinematic data were collected during the typing task. Variables of interest were median nerve cross-sectional area, flattening ratio, and swelling ratio at the pisiform; subject characteristics (age, gender, BMI, wrist circumference, typing speed) and wrist joint angles.
Findings: Cross-sectional area and swelling ratio increased after 30 and 60 min of typing, and then decreased to baseline after 30 min of rest. Peak ulnar deviation contributed to changes in cross-sectional area after 30 min of typing.
Interpretation: Results from this study confirmed a typing task causes changes in the median nerve, and changes are influenced by level of ulnar deviation. Furthermore, changes in the median nerve are present until cessation of the activity. While it is unclear if these changes lead to long-term symptoms or nerve injury, their existence adds to the evidence of a possible link between carpal tunnel syndrome and keyboarding.

AB This study examined the psychometric properties of the Portuguese version of the ISMI scale in a sample of 253 adult psychiatric outpatients. The exploratory factor analysis replicated the five factor structure of the scale. The results revealed good internal consistency. Criterion-related validity supported the variability in response to stigma across clinical diagnoses. Thus, the Portuguese version of the ISMI scale can be considered appropriate to measure and differentiate between stigmatization experiences. Also, in order to design more focused approaches aimed to reduce the negative effects of internalized stigma, its use in institutional and in community-based mental health services is recommended.

AB Tropical infectious diseases (IDs) remain a rare complication in transplant recipients even in tropical settings, but this topic has become increasingly important during the last decade due to multiple factors. Interestingly, non-tropical countries report most of the experiences with tropical diseases. The reported experience from non-endemic regions, however, does not always reflect the experience of endemic areas. Most of the guidelines and recommendations in the literature may not be applicable in tropical settings due to logistical difficulties, cost, and lack of proven benefit. In addition, certain post-transplant prevention measures, as prophylaxis and reducing exposure risk, are not feasible. Nonetheless, risk assessment and post-transplant management of tropical IDs in tropical areas should not be neglected, and clinicians need to have a higher clinical awareness for tropical ID occurring in this population. Herein, we review the more significant tropical ID in transplant patients, focusing on relevant experience reported by tropical settings.

AB ObjectivesCommunity viral load (CVL) estimates vary based on analytic methods. We extended the CVL concept and used data from the Veterans Health Administration (VA) to determine trends in the health care system viral load (HSVL) and its sensitivity to varying definitions of the clinical population and assumptions regarding missing data.
MethodsWe included HIV-infected patients in the Veterans Aging Cohort Study, 2000-2010, with at least one documented CD4 count, HIV-1 RNA or antiretroviral prescription (n=37318). We created 6-month intervals including patients with at least one visit in the past 2 years. We assessed temporal trends in clinical population size, patient clinical status and mean HSVL and explored the impact of varying definitions of the clinical population and assumptions about missing viral load.
ResultsThe clinical population size varied by definition, increasing from 16000-19000 patients in 2000 to 23000-26000 in 2010. The proportion of patients with suppressed HIV-1 RNA increased over time. Over 20% of patients had no viral load measured in a given interval or the past 2 years. Among patients with a current HIV-1 RNA, mean HSVL decreased from 97800 HIV-1 RNA copies/mL in 2000 to 2000 copies/mL in 2010. When current HIV-1 RNA data were unavailable and the HSVL was recalculated using the last available HIV-1 RNA, HSVL decreased from 322300 to 9900 copies/mL. HSVL was underestimated when using only current data in each interval.
ConclusionsThe CVL concept can be applied to a health care system, providing a measure of health care quality. Like CVL, HSVL estimates depend on definitions of the clinical population and assumptions about missing data.

AB ObjectivesAs approximate to 40% of HIV-infected individuals experience neurocognitive decline, we investigated whether proton magnetic resonance spectroscopic imaging (H-1-MRSI) detects early metabolic abnormalities in the cerebral cortex of a simian immunodeficiency virus (SIV)-infected rhesus monkey model of neuroAIDS.
MethodsThe brains of five rhesus monkeys before and 4 or 6 weeks after SIV infection (with CD8(+) T-cell depletion) were assessed with T-2-weighted quantitative magnetic resonance imaging (MRI) and 16x16x4 multivoxel H-1-MRSI (echo time/repetition time=33/1440ms). Grey matter and white matter masks were segmented from the animal MRIs and used to produce cortical masks co-registered to H-1-MRSI data to yield cortical metabolite concentrations of the glial markers myo-inositol (mI), creatine (Cr) and choline (Cho), and of the neuronal marker N-acetylaspartate (NAA). The cortex volume within the large, 28cm(3) (approximate to 35% of total monkey brain) volume of interest was also calculated for each animal pre- and post-infection. Mean metabolite concentrations and cortex volumes were compared pre- and post-infection using paired sample t-tests.
ResultsThe mean (standard deviation) pre-infection concentrations of the glial markers mI, Cr and Cho were 5.8 +/- 0.9, 7.2 +/- 0.4 and 0.9 +/- 0.1mM, respectively; these concentrations increased 28% (p approximate to 0.06), 15% and 10% (both p<0.05), respectively, post-infection. The mean concentration of neuronal marker NAA remained unchanged (7.0 +/- 0.6mM pre-infection vs. 7.3 +/- 0.8mM post-infection; p approximate to 0.37). The mean cortex volume was also unchanged (8.1 +/- 1.1 cm(3) pre-infection vs. 8.3 +/- 0.5 cm(3) post-infection; p approximate to 0.76).
ConclusionsThese results support the hypothesis that early cortical glial activation occurs after SIV infection prior to the onset of neurodegeneration. This suggests HIV therapeutic interventions should potentially target early glial activation in the cerebral cortex.

AB The human pulvinar is the largest thalamic area in terms of size and cortical connectivity. Although much is known about regional pulvinar structural anatomy, relatively little is known about pulvinar functional anatomy in humans. Cooccurrence of experimentally induced brain activity is a traditional metric used to establish interregional brain connectivity and forms the foundation of functional neuroimaging connectivity analyses. Because functional neuroimaging studies report task-related coactivations within a standardized space, meta-analysis of many whole-brain studies can define the brain's interregional coactivation across many tasks. Such an analysis can also detect and define variations in functional coactivations within a particular region. Here we use coactivation profiles reported in approximate to 7,700 functional neuroimaging studies to parcellate and define the pulvinar's functional anatomy. Parcellation of the pulvinar's coactivation profile identified five clusters per pulvinar of distinct functional coactivation. These clusters showed a high degree of symmetry across hemispheres and correspondence with the human pulvinar's cytoarchitecture. We investigated the functional coactivation profiles of each resultant pulvinar cluster with meta-analytic methods. By referencing existent neuroimaging and lesion-deficit literature, these profiles make a case for regional pulvinar specialization within the larger human attention-controlling network. Reference to this literature also informs specific hypotheses that can be tested in subsequent studies in healthy and clinical populations. Hum Brain Mapp 36:2417-2431, 2015.

AB We sought to determine whether functional connectivity streams that link sensory, attentional, and higher-order cognitive circuits are atypical in attention-deficit/hyperactivity disorder (ADHD). We applied a graph-theory method to the resting-state functional magnetic resonance imaging data of 120 children with ADHD and 120 age-matched typically developing children (TDC). Starting in unimodal primary cortexvisual, auditory, and somatosensorywe used stepwise functional connectivity to calculate functional connectivity paths at discrete numbers of relay stations (or link-step distances). First, we characterized the functional connectivity streams that link sensory, attentional, and higher-order cognitive circuits in TDC and found that systems do not reach the level of integration achieved by adults. Second, we searched for stepwise functional connectivity differences between children with ADHD and TDC. We found that, at the initial steps of sensory functional connectivity streams, patients display significant enhancements of connectivity degree within neighboring areas of primary cortex, while connectivity to attention-regulatory areas is reduced. Third, at subsequent link-step distances from primary sensory cortex, children with ADHD show decreased connectivity to executive processing areas and increased degree of connections to default mode regions. Fourth, in examining medication histories in children with ADHD, we found that children medicated with psychostimulants present functional connectivity streams with higher degree of connectivity to regions subserving attentional and executive processes compared to medication-naive children. We conclude that predominance of local sensory processing and lesser influx of information to attentional and executive regions may reduce the ability to organize and control the balance between external and internal sources of information in ADHD.

AB Past neuroimaging studies have focused on identifying specialized functional brain systems for processing different components of reading, such as orthography, phonology, and semantics. More recently, a few experiments have been performed to look into the integration and interaction of distributed neural systems for visual word recognition, suggesting that lexical processing in alphabetic languages involves both ventral and dorsal neural pathways originating from the visual cortex. In the present functional magnetic resonance imaging study, we tested the multiple pathways model with Chinese character stimuli and examined how the neural systems interacted in reading Chinese. Using dynamic causal modeling, we demonstrated that visual word recognition in Chinese engages the ventral pathway from the visual cortex to the left ventral occipitotemporal cortex, but not the dorsal pathway from the visual cortex to the left parietal region. The ventral pathway, however, is linked to the superior parietal lobule and the left middle frontal gyrus (MFG) so that a dynamic neural network is formed, with information flowing from the visual cortex to the left ventral occipitotemporal cortex to the parietal lobule and then to the left MFG. The findings suggest that cortical dynamics is constrained by the differences in how visual orthographic symbols in writing systems are linked to spoken language. Hum Brain Mapp 36:2580-2591, 2015.

AB Oral contraceptive pills (OCs), which are used to prevent pregnancy by the majority of women in the United States, contain steroid hormones that may affect the brain's structure and function. In this investigation, we tested the hypothesis that OC use is associated with differences in brain structure using a hypothesis-driven, surface-based approach. In 90 women, (44 OC users, 46 naturally-cycling women), we compared the cortical thickness of brain regions that participate in the salience network and the default mode network, as well as the volume of subcortical regions in these networks. We found that OC use was associated with significantly lower cortical thickness measurements in the lateral orbitofrontal cortex and the posterior cingulate cortex. These regions are believed to be important for responding to rewards and evaluating internal states/incoming stimuli, respectively. Further investigations are needed to determine if cortical thinning in these regions are associated with behavioral changes, and also to identify whether OC use is causally or only indirectly related to these changes in brain morphology.

AB We confirmed strong association of rs78378222:A>C (per allele odds ratio [OR] = 3.14; P = 6.48 x 10(-11)), a germline rare single-nucleotide polymorphism (SNP) in TP53, via imputation of a genome-wide association study of glioma (1,856 cases and 4,955 controls). We subsequently performed integrative analyses on the Cancer Genome Atlas (TCGA) data for GBM (glioblastoma multiforme) and LUAD (lung adenocarcinoma). Based on SNP data, we imputed genotypes for rs78378222 and selected individuals carrying rare risk allele (C). Using RNA sequencing data, we observed aberrant transcripts with approximate to 3 kb longer than normal for those individuals. Using exome sequencing data, we further showed that loss of haplotype carrying common protective allele (A) occurred somatically in GBM but not in LUAD. Our bioinformatic analysis suggests rare risk allele (C) disrupts mRNA termination, and an allelic loss of a genomic region harboring common protective allele (A) occurs during tumor initiation or progression for glioma.

AB Mucosa-associated invariant T (MAIT) cells express the semi-invariant T-cell receptor TRAV1-2 and detect a range of bacteria and fungi through the MHC-like molecule MR1. However, knowledge of the function and phenotype of bacteria-reactive MR1-restricted TRAV1-2(+) MAIT cells from human blood is limited. We broadly characterized the function of MR1-restricted MAIT cells in response to bacteria-infected targets and defined a phenotypic panel to identify these cells in the circulation. We demonstrated that bacteria-reactive MR1-restricted T cells shared effector functions of cytolytic effector CD8(+) T cells. By analysing an extensive panel of phenotypic markers, we determined that CD26 and CD161 were most strongly associated with these T cells. Using FACS to sort phenotypically defined CD8(+) subsets we demonstrated that high expression of CD26 on CD8(+)TRAV1-2(+) cells identified with high specificity and sensitivity, bacteria-reactive MR1-restricted T cells from human blood. CD161(hi) was also specific for but lacked sensitivity in identifying all bacteria-reactive MR1-restricted T cells, some of which were CD161(dim). Using cell surface expression of CD8, TRAV1-2, and CD26(hi) in the absence of stimulation we confirm that bacteria-reactive T cells are lacking in the blood of individuals with active tuberculosis and are restored in the blood of individuals undergoing treatment for tuberculosis.

AB OBJECTIVE. To identify risk factors for recurrent methicillin-resistant Staphylococcus aureus (MRSA) colonization.
DESIGN. Prospective cohort study conducted from January 1, 2010, through December 31, 2012.
SETTING. Five adult and pediatric academic medical centers.
PARTICIPANTS. Subjects (ie, index cases) who presented with acute community-onset MRSA skin and soft-tissue infection.
METHODS. Index cases and all household members performed self-sampling for MRSA colonization every 2 weeks for 6 months. Clearance of colonization was defined as 2 consecutive sampling periods with negative surveillance cultures. Recurrent colonization was defined as any positive MRSA surveillance culture after clearance. Index cases with recurrent MRSA colonization were compared with those without recurrence on the basis of antibiotic exposure, household demographic characteristics, and presence of MRSA colonization in household members.
RESULTS. The study cohort comprised 195 index cases; recurrent MRSA colonization occurred in 85 (43.6%). Median time to recurrence was 53 days (interquartile range, 36-84 days). Treatment with clindamycin was associated with lower risk of recurrence (odds ratio, 0.52; 95% CI, 0.29-0.93). Higher percentage of household members younger than 18 was associated with increased risk of recurrence (odds ratio, 1.01; 95% CI, 1.00-1.02). The association between MRSA colonization in household members and recurrent colonization in index cases did not reach statistical significance in primary analyses.
CONCLUSION. A large proportion of patients initially presenting with MRSA skin and soft-tissue infection will have recurrent colonization after clearance. The reduced rate of recurrent colonization associated with clindamycin may indicate a unique role for this antibiotic in the treatment of such infection.

INTRODUCTION; WEAR
AB Vitamin E diffusion into highly cross-linked polyethylene (E-XLPE) is a method for enhancing oxidative stability of acetabular liners. The purpose of this study was to evaluate in vivo penetration of E-XLPE using radiostereometric analysis (RSA). Eighty-four hips were recruited into a prospective 10-year RSA. This is the first evaluation of the multicenter cohort after 3-years. All patients received E-XLPE liners (E1, Biomet) and porous-titanium coated cups (Regenerex, Biomet). There was no difference (P = 0.450) in median femoral head penetration into the E-XLPE liners at 3-years comparing cobalt-chrome heads (-0.028 mm; inter-quartile range (IQR) -0.065 to 0.047) with ceramic heads (-0.043 mm, IQR -0.143 to 0.042). The 3-year follow-up indicates minimal E-XLPE liner penetration regardless of head material and minimal early cup movement. (C) 2015 Elsevier Inc. All rights reserved.

AB We conducted in-depth case studies of 10 health care professionals who actively provide primary medical care to adults with autism spectrum disorders. The study sought to understand their experiences in providing this care, the training they had received, the training they lack and their suggestions for encouraging more physicians to provide this care. Qualitative data were gathered by phone using a structured interview guide and analyzed using the framework approach. Challenges to providing care were identified at the systems, practice and provider, and education and training levels. Solutions and interventions targeting needed changes at each level were also proposed. The findings have implications for health care reform, medical school and residency training programs, and the development of best practices.

ID CRANIAL COMPUTED-TOMOGRAPHY; SUBARACHNOID HEMORRHAGE; THUNDERCLAP
HEADACHE; DIAGNOSIS
AB Background: Reversible cerebral vasoconstriction syndrome (RCVS) is an underappreciated and poorly understood cause of thunderclap headache (TCH). Although self-limited in the majority of patients, incidence is increasing, with presentations overlapping considerably with life-threatening conditions, such as aneurysmal subarachnoid hemorrhage and stroke. In addition, radiographic findings seen in RCVS are also present in primary angiitis of the central nervous system (PACNS). Misdiagnosis of RCVS might subject patients to unnecessary invasive testing and immunosuppressive therapy. Furthermore, the recommended treatment of glucocorticoids used in PACNS can be harmful in RCVS. RCVS is not a benign condition, as patients can have ischemic or hemorrhagic complications leading to persistent neurologic deficits and even death. Current treatments, guided only by expert consensus, have no proven effect on these complications, which argues the need for accurate identification of patients with RCVS and prospective studies to validate treatment and inform prognoses. Case Report: We describe a previously healthy male who presented to the emergency department after 2 episodes of TCH and angiography consistent with RCVS. Why Should An Emergency Physician Be Aware of This?: RCVS is a common but underappreciated cause of TCH. The likelihood of misdiagnosing RCVS following the accepted diagnostic algorithm of acute headache in the emergency department is high due to a lack of clinical awareness and common features shared with other headache syndromes. Emergency department physicians must broaden the differential in patients presenting to the emergency department with TCH to include RCVS and be familiar with the accepted treatments and appropriate follow-up.

AB Background: As bedside ultrasound (BUS) is being increasingly taught and incorporated into emergency medicine practice, measurement of BUS competency is becoming more important. The commonly adopted experiential approach to BUS competency has never been validated on a large scale, and has some limitations by design. Objective: Our aim was to introduce and report preliminary testing of a novel emergency BUS image rating scale (URS). Methods: Gallbladder BUS was selected as the test case. Twenty anonymous BUS image sets (still images and clips) were forwarded electronically to 16 reviewers (13 attendings, 3 fellows) at six training sites across the United States. Each reviewer rated the BUS sets using the pilot URS that consisted of three components, with numerical values assigned to each of the following aspects: Landmarks, Image Quality, and Annotations. Reviewers also decided whether or not each BUS set would be "Clinically Useful." Kendall tau s were calculated as a measure of concordance among the reviewers. Results: Among the 13 attendings, image review experience ranged from 2-15 years, 5-300 scans per week, and averaged 7.8 years and 60 images. Kendall tau s for each aspect of the URS were: Landmarks: 0.55; Image Quality: 0.57; Annotation: 0.26; Total Score: 0.63, and Clinical Usefulness: 0.45. All URS elements correlated significantly with clinical usefulness (p < 0.001). The correlation coefficient between each attending reviewer and the entire group ranged from 0.48-0.69, and was independent of image review experience beyond fellowship training. Conclusion: Our novel URS had moderate-to-good inter-rater agreement in this pilot study. Based on these results, the URS will be modified for use in future investigations. (C) 2015 Elsevier Inc.

AB Background: In part 1 of this two-part review, we discussed which risk factors, historical features, and physical findings increase risk for pulmonary embolism (PE) in symptomatic emergency department (ED) patients. Objectives: Use published evidence to describe criteria that a reasonable and prudent clinician can use to initiate and guide the process of excluding and diagnosing PE. Discussion: The careful and diligent emergency physician can use clinical criteria to safely obviate a formal evaluation of PE, including the use of gestalt reasoning and the pulmonary embolism rule-out criteria (PERC rule, Table 2, part 1). We present published clinical and radiographic features of patients with PE who eluded diagnosis in the ED. D-dimer can be used to exclude PE in many patients, and employing age-based adjustments to the threshold to define an abnormal value can further reduce patient exposure to pulmonary vascular imaging. Moreover, we discuss benefits, limitations, and potential harms of computed tomographic pulmonary vascular imaging relevant to patients and the practice of emergency care. We present algorithms to guide exclusion and diagnosis of PE in patients with suspected PE, including those who are pregnant. Conclusions: Reasonable and prudent emergency clinicians can exclude PE in symptomatic ED patients on clinical grounds alone in many patients, and many more can have PE ruled out by use of the D-dimer.

AB New trends have emerged regarding the best minimally invasive access approaches to perform gastrointestinal surgery. However, these newer approaches are seen critically by those who demand a more strict assessment of outcomes and safety. An international panel of expert gathered at the 2014 American College of Surgeons Meeting with the goal of providing an evidence-based understanding of the real value of these approaches in gastrointestinal surgery. The panel has compared the efficacy and safety of most established approaches to gastrointestinal diseases to those of new treatment modalities: peroral esophageal myotomy vs. laparoscopic myotomy for achalasia, transgastric vs. transvaginal approach, and single-incision vs. multi-port access minimally invasive surgery. The panel found that (1) the outcome of these new approaches was not superior to that of established surgical procedures; (2) the new approaches are generally performed in few highly specialized centers; and (3) transgastric and transvaginal approaches might be safe and feasible in very experienced hands, but cost, training, operative time, and tools seem to limit their application for the treatment of common procedures such as cholecystectomy and appendectomy. Because the expected advantages of new approaches have yet to be proven in controlled trials, new approaches should be considered for adoption into practice only after thorough analyses of their efficacy and effectiveness and appropriate training.

AB The incidence and the severity of Clostridium difficile infection (CDI) have increased significantly over the last decade, especially in high-risk populations such as patients with inflammatory bowel disease (IBD). Surgeons must be able to both identify and minimize the risk of CDI in their own surgical patients and determine which CDI patients will benefit from surgery.
We sought to define the risk factors, compare the treatment options, define the surgical indications, and identify factors that affect surgical outcomes for CDI based on the currently available literature.
Antibiotic use, exposure to the C. difficile bacteria, IBD, and higher levels of co-morbidity are all risk factors for CDI. The majority of CDI can be treated with antibiotics. Severe or fulminant colitis, however, has a high potential for poor outcome, but experience and some data suggest a lower mortality rate with colectomy rather than with continued medical treatment. Open total abdominal colectomy with end ileostomy is typically the preferred surgical strategy. It is often difficult to determine which patients will fail medical management as some may not manifest clinical signs of severe infection. Surrogate parameters of failure of medical therapy include respiratory and/or renal insufficiency, age greater than 60 years, peripheral vascular disease, congestive heart failure, and coagulopathy, all of which have been associated with worse surgical outcomes. Evidence suggests that in appropriately selected patients, colectomy performed before the development of shock requiring vasopressors, respiratory failure, renal failure, multi-organ dysfunction, and mental status changes may reduce mortality of the most severe forms of colitis. For less severe or recurrent presentations, creation of a loop ileostomy with intra-operative colonic lavage, fecal microbiota transfer, and C. difficile vaccinations are being discussed but have only been studied in small case-controlled series.
Prevention, containment, and non-surgical treatment are the cornerstone of management for CDI. However, the most severe forms with toxic colitis benefit from involvement of a surgical team. Swift open total abdominal colectomy with end ileostomy in patients with severe or fulminant C. difficile colitis has the best chance to reduce mortality if it is not delayed until shock, end organ damage, vasopressor requirement, mental status changes develop. Less aggressive approaches may be appropriate for milder and refractory forms but require further study before their applicability can be determined.

AB Improving colorectal cancer (CRC) screening rates for patients from socioeconomically disadvantaged backgrounds is a recognized public health priority.
Our aim was to determine if implementation of a system-wide screening intervention could reduce disparities in the setting of improved overall screening rates.
This was an interrupted time series (ITS) analysis before and after a population management intervention.
Patients eligible for CRC screening (age 52-75 years without prior total colectomy) in an 18-practice research network from 15 June 2009 to 15 June 2012 participated in the study.
The Technology for Optimizing Population Care (TopCare) intervention electronically identified patients overdue for screening and facilitated contact by letter or telephone scheduler, with or without physician involvement. Patients identified by algorithm as high risk for non-completion entered into intensive patient navigation.
Patients were dichotomized as a parts per thousand currency signaEuro parts per thousand high school diploma (a parts per thousand currency sign HS), an indicator of socioeconomic disadvantage, vs. > HS diploma (> HS). The monthly disparity between a parts per thousand currency signaEuro parts per thousand HS and > HS with regard to CRC screening completion was examined.
At baseline, 72 % of 47,447 eligible patients had completed screening, compared with 75 % of 51,442 eligible patients at the end of follow-up (p < 0.001). CRC screening completion was lower in a parts per thousand currency signaEuro parts per thousand HS vs. > HS patients in June 2009 (65.7 % vs. 74.5 %, p < 0.001) and remained lower in June 2012 (69.4 % vs. 76.7 %, p < 0.001). In the ITS analysis, which accounts for secular trends, TopCare was associated with a significant decrease in the CRC screening disparity (0.7 %, p < 0.001). The effect of TopCare represents approximately 99 additional a parts per thousand currency signaEuro parts per thousand HS patients screened above prevailing trends, or 26 life-years gained had these patients remained unscreened.
A multifaceted population management intervention sensitive to the needs of vulnerable patients modestly narrowed disparities in CRC screening, while also increasing overall screening rates. Embedding interventions for vulnerable patients within larger population management systems represents an effective approach to increasing overall quality of care while also decreasing disparities.

AB Hospital readmissions are expensive and they may signal poor quality of care. Whether functional status is related to hospital readmissions using a representative U.S sample remains unexplored .
We aimed to assess the relationship between functional status and all-cause 30-day hospital readmissions using a representative sample of the US population.
This was a retrospective observational study (2003-2011).
The study included 3,772 patients who completed the SF-12 before being hospitalized. Three hundred and eighteen (8.4 %) were readmitted within 30 days after being discharged.
The Medical Expenditure Panel Survey (MEPS) was employed. Functional status was measured with the Short-Form 12-Item Health Survey Version 2A (R) (SF-12). The probability of being readmitted was estimated using a logistic model controlling for demographic characteristics, comorbid conditions, insurance coverage, physical (PCS) and mental (MCS) summaries of the SF-12, reason for hospitalization, length of hospital stay, region, and residential area.
A one-unit difference in PCS reduced the odds of readmission by 2 % (odds ratio 0.98 [95 % CI, 0.97 to 0.99]; p < 0.001), which implies an 18 % reduction in the odds of readmissions for a ten-unit difference (one standard deviation) in PCS. The c-statistic of the model was 0.72.
Baseline physical function is associated with hospital readmissions. The SF-12 improves the ability to identify patients at high risk of hospital readmission.

AB Background & Aims: Inclusion of liver grafts from cardiac death donors (CDD) would increase the availability of donor livers but is hampered by a higher risk of primary non-function. Here, we seek to determine mechanisms that contribute to primary non-function of liver grafts from CDD with the goal to develop strategies for improved function and outcome, focusing on c-Jun-N-terminal kinase (JNK) activation and mitochondrial depolarization, two known mediators of graft failure.
Methods: Livers explanted from wild-type, inducible nitric oxide synthase knockout (iNOS(-/-)), JNK1(-/-) or JNK2(-/-) mice after 45-min aorta clamping were implanted into wild-type recipients. Mitochondrial depolarization was detected by intravital confocal microscopy in living recipients.
Results: After transplantation of wild-type CDD livers, graft iNOS expression and 3-nitrotyrosine adducts increased, but hepatic endothelial NOS expression was unchanged. Graft injury and dysfunction were substantially higher in CDD grafts than in non-CDD grafts. iNOS deficiency and inhibition attenuated injury and improved function and survival of CDD grafts. JNK1/2 and apoptosis signal-regulating kinase-1 activation increased markedly in wild-type CDD grafts, which was blunted by iNOS deficiency. JNK inhibition and JNK2 deficiency, but not JNK1 deficiency, decreased injury and improved function and survival of CDD grafts. Mitochondrial depolarization and binding of phospho-JNK2 to Sab, a mitochondrial protein linked to the mitochondrial permeability transition, were higher in CDD than in non-CDD grafts. iNOS deficiency, JNK inhibition and JNK2 deficiency all decreased mitochondrial depolarization and blunted ATP depletion in CDD grafts. JNK inhibition and deficiency did not decrease 3-nitrotyrosine adducts in CDD grafts.
Conclusion: The iNOS-JNK2-Sab pathway promotes CDD graft failure via increased mitochondrial depolarization, and is an attractive target to improve liver function and survival in CDD liver transplantation recipients.

TI Dual-task interference and brain structural connectivity in people with
Parkinson's disease who freeze

ID PROGRESSIVE SUPRANUCLEAR PALSY; PEDUNCULOPONTINE NUCLEUS; BASAL GANGLIA;

AB Background Freezing of gait in people with Parkinson's disease (PD) is likely related to attentional control (ie, ability to divide and switch attention). However, the neural pathophysiology of altered attentional control in individuals with PD who freeze is unknown. Structural connectivity of the pedunculopontine nucleus has been related to freezing and may play a role in altered attentional control; however, this relationship has not been investigated. We measured whether dual-task interference, defined as the reduction in gait performance during dual-task walking, is more pronounced in individuals with PD who freeze, and whether dual-task interference is associated with structural connectivity and/or executive function in this population.
Methods We measured stride length in 13 people with PD with and 12 without freezing of gait during normal and dual-task walking. We also assessed asymmetry of pedunculopontine nucleus structural connectivity via diffusion tensor imaging and performance on cognitive tests assessing inhibition and set-shifting, cognitive domains related to freezing.
Results Although stride length was not different across groups, change in stride length between normal and dual-task gait (ie, dual-task interference) was more pronounced in people with PD who freeze compared to non-freezers. Further, in people with PD who freeze, dual-task interference was correlated with asymmetry of pedunculopontine nucleus structural connectivity, Go-NoGo target accuracy (ability to release a response) and simple reaction time.
Conclusions These results support the hypothesis that freezing is related to altered attentional control during gait, and suggest that differences in pedunculopontine nucleus connectivity contribute to poorer attentional control in people with PD who freeze.

AB Colorectal cancer, unlike many other malignancies, may be preventable. Recent studies have demonstrated an inverse association between nut consumption and incidence of colon cancer; however, the underlying mechanisms are not fully understood. An emerging concept suggests that microribonucleic acids (miRNAs) may help explain the relationship between walnut consumption and decreased colorectal neoplasia risk.
Seven days after HT-29 colon cancer cell injection, mice were randomized to either control or walnut diets for 25 days of diet treatment. Thirty samples of tumor and of omental adipose were analyzed to determine changes in lipid composition in each dietary group. In the tumors of the walnut-containing diet, we found significant increases in alpha-linolenic, eicosapentaenoic, docosahexaenoic and total omega-3 acids, and a decrease in arachidonic acid, as compared to the control diet. Final tumor size measured at sacrifice was negatively associated with percentage of total omega-3 fatty acid composition (r=-0.641, P=.001). MicroRNA expression analysis of colorectal tumor tissue revealed decreased expression of miRNAs 1903, 467c and 3068 (P<.05) and increased expression of miRNA 297a* (P=.0059) in the walnut-treated group as compared to control diet.
Our results indicate that changes in the miRNA expression profiles likely affect target gene transcripts involved in pathways of anti-inflammation, antivascularization, antiproliferation and apoptosis. We also demonstrate the incorporation of protective fatty acids into colonic epithelium of walnut-fed mice, which may independently alter miRNA expression profiles itself. Future studies of the mechanism of widespread miRNA regulation by walnut consumption are needed to offer potential prognostic and therapeutic targets. (C) 2015 Elsevier Inc. All rights reserved.

AB Background: Parenteral nutrition (PN) is available as individualized prescriptions frequently prepared with an automated compounding device or as commercially prepared premixed solutions. Our institution exclusively used individualized PN until an amino acid shortage forced a temporary switch to premixed solutions. In general, premixed solutions contain lower electrolyte levels than individualized formulations prescribed for patients with normal organ function. We aimed to quantify supplemental intravenous piggyback (IVPB) electrolyte use in adult patients receiving individualized and premixed PN and to quantify any effect on difference in the cost of therapy. Methods: We compared use of supplemental IVPB electrolytes administered to patients receiving PN during consecutive periods prior to and during the amino acid shortage. Electrolyte IVPBs tabulated were potassium chloride, 10 and 20 mEq; magnesium sulfate, 2 g and 4 g; potassium phosphate, 7.5 and 15 mmol; and sodium phosphate, 7.5 and 15 mmol IVPB. Results: There was no statistical difference in the number of PN formulations administered per day during each period (14.7 +/- 3.9 vs 14.0 +/- 2.6, individualized vs premixed, respectively). Total IVPB electrolytes prescribed per day increased significantly from the individualized PN period to the premixed PN period (7.03 +/- 3.8 vs 13.8 +/- 6.8; P < .0001). The additional IVPB electrolyte supplementation required in patients receiving premixed PN was associated with an additional $11,855.74 cost per 30 days of therapy compared with those who received individualized PN. Conclusion: Inpatient use of premixed PN results in a significant increase in IVPB electrolyte supplementation and cost compared with individualized PN use.

AB Research on empathy in schizophrenia has relied on dated self-report scales that do not conform to contemporary social neuroscience models of empathy. The current study evaluated the structure and correlates of the recently-developed Questionnaire of Cognitive and Affective Empathy (QCAE) in schizophrenia. This measure, whose structure and validity was established in healthy individuals, includes separate scales to assess the two main components of empathy: Cognitive Empathy (assessed by two subscales) and Affective Empathy (assessed by three subscales). Stable outpatients with schizophrenia (n = 145) and healthy individuals (n = 45) completed the QCAE, alternative measures of empathy, and assessments of clinical symptoms, neurocognition, and functional outcome. Exploratory and confirmatory factor analyses provided consistent support for a two-factor solution in the schizophrenia group, justifying the use of separate cognitive and affective empathy scales in this population. However, one of the three Affective Empathy subscales was not psychometrically sound and was excluded from further analyses. Patients reported significantly lower Cognitive Empathy but higher Affective Empathy than controls. Among patients, the QCAE scales showed significant correlations with an alternative self-report empathy scale, but not with performance on an empathic accuracy task. The QCAE Cognitive Empathy subscales also showed significant, though modest, correlations with negative symptoms and functional outcome. These findings indicate that structure of self-reported empathy is similar in people with schizophrenia and healthy subjects, and can be meaningfully compared between groups. They also contribute to emerging evidence that some aspects of empathy may be intact or hyper-responsive in schizophrenia. (C) 2015 Elsevier Ltd. All rights reserved.

AB The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) formally introduced a dissociative subtype of posttraumatic stress disorder (PTSD). This study examined the proportion of U.S. veterans with DSM-5 PTSD that report dissociative symptoms; and compared veterans with PTSD with and without the dissociative subtype and trauma-exposed controls on sociodemographics, clinical characteristics, and quality of life. Multivariable analyses were conducted on a nationally representative sample of 1484 veterans from the National Health and Resilience in Veterans Study (second baseline survey conducted September October, 2013). Of the 12.0% and 5.2% of veterans who screened positive for lifetime and past-month DSM-5 PTSD, 19.2% and 16.1% screened positive for the dissociative subtype, respectively. Among veterans with PTSD, those with the dissociative subtype reported more severe PTSD symptoms, comorbid depressive and anxiety symptoms, alcohol use problems, and hostility than those without the dissociative subtype. Adjusting for PTSD symptom severity, those with the dissociative subtype continued to report more depression and alcohol use problems. These results underscore the importance of assessing, monitoring, and treating the considerable proportion of veterans with PTSD and dissociative symptoms. Published by Elsevier Ltd.

AB Objectives: In this exploratory study, we aimed to investigate whether polymorphisms in excision repair cross-complementing group 1 (ERCC1) and excision repair cross-complementing group 2/xeroderma pigmentosum group D (ERCC2/XPD) in the nucleotide excision repair (NER) pathways associated with DNA adducts in human lung tissue. We also analyzed the association stratified by the major histologic subtypes of non-small cell lung cancer (NSCLC): adenocarcinoma (ADC) and squamous cell carcinoma (SQCC).
Methods: The study population consisted of 107 early stage NSCLC patients from the Massachusetts General Hospital (MGH) in Boston who underwent curative surgical resection. Genotyping was completed for SNPs in ERCC1 [C8092A (rs3212986) and C11 8T (rs11615)] and ERCC2/XPD [Asp312Asn (rs1799793) and Lys751Gln (rs1052559)] using a PCR-RFLP method and the PCR with fluorescent allele-specific oligonucleotide probes (Taqman). DNA adduct levels were measured as relative adduct levels per 10(10) nucleotides by P-32-postlabeling in non-tumor lung tissue.
Results: After adjusting for potential confounders, lung DNA adduct levels increased by 103.2% [95% confidence interval (CI), -11.5 to 366.6] for ERCC2/XPD rs1799793AA genotype compared with their corresponding wild type homozygous genotypes in overall NSCLC, but the difference did not reach statistical significance. When we stratified by the subtypes of NSCLC, we found that DNA adducts levels in lung increased by 204.9% (95% CI, 0.8 to 822.2, P=0.059) for ERCC2/XPD rs1799793AA genotype in subjects with SQCC and the trend was statistically significant (P for trend = 0.0489).
Conclusions: Polymorphisms in ERCC2/XPD Asp312Asn may be associated with increased DNA adduct levels in the lung, especially among subjects with SQCC. Further large scale studies are needed to confirm our findings. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB Objectives: Veliparib (V) potentiated therapeutic efficacy of cisplatin (C) and etoposide (E) in preclinical models of SCLC. We conducted this phase 1 study to establish the safety of the combination in human subjects.
Materials and methods: The study employed the 3 +3 dose escalation design to establish the safety and recommended phase 2 dose (RP2D) of V when combined with fixed doses of C (75 mg/m(2) on day 1) and E (100 mg/m(2) on days 1-3) in a 21-day cycle. The starting dose of V was 60 mg (bid days 1-7) with plan to escalate to 100 mg (days 1-7) or de-escalate to 40 mg (days 1-7) depending on the dose limiting toxicity (DLT) experience during cycle 1. Patients with treatment-naive, extensive stage SCLC were included.
Results: The study enrolled 9 patients: M/F (4/5); median age (60); White/African American (8/1). V was tolerated at the 60 mg (DLT in 0 of 3 patients) and 100 mg dose (DLT in 1 of 6 patients; grade 5 cardiac failure). Veliparib at 100 mg in combination with standard doses of C and E was established as the RP2D. Grades 3-5 adverse events irrespective of attribution during cycle 1 included: dehydration (1), diarrhea (1), fatigue (1), febrile neutropenia (1), heart failure (1), leukopenia (6), lymphopenia (1), nausea (2), neutropenia (8), respiratory failure (1), and thrombocytopenia (2). Investigator-assessed efficacy outcome in 7 evaluable patients were stable disease in 2/7 (28.6%), partial response in 4/7 (57.1%), and complete response in 1/7 (14.3%) patients.
Conclusions: This study demonstrated the safety of combining veliparib with cisplatin and etoposide in previously untreated SCLC patients. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB PurposeTo develop and evaluate the performance of an acquisition and reconstruction method for accelerated MR spectroscopic imaging (MRSI) through undersampling of spiral trajectories.
Theory and MethodsA randomly undersampled spiral acquisition and sensitivity encoding (SENSE) with total variation (TV) regularization, random SENSE+TV, is developed and evaluated on single-slice numerical phantom, in vivo single-slice MRSI, and in vivo three-dimensional (3D)-MRSI at 3 Tesla. Random SENSE+TV was compared with five alternative methods for accelerated MRSI.
ResultsFor the in vivo single-slice MRSI, random SENSE+TV yields up to 2.7 and 2 times reduction in root-mean-square error (RMSE) of reconstructed N-acetyl aspartate (NAA), creatine, and choline maps, compared with the denoised fully sampled and uniformly undersampled SENSE+TV methods with the same acquisition time, respectively. For the in vivo 3D-MRSI, random SENSE+TV yields up to 1.6 times reduction in RMSE, compared with uniform SENSE+TV. Furthermore, by using random SENSE+TV, we have demonstrated on the in vivo single-slice and 3D-MRSI that acceleration factors of 4.5 and 4 are achievable with the same quality as the fully sampled data, as measured by RMSE of reconstructed NAA map, respectively.
ConclusionWith the same scan time, random SENSE+TV yields lower RMSEs of metabolite maps than other methods evaluated. Random SENSE+TV achieves up to 4.5-fold acceleration with comparable data quality as the fully sampled acquisition. Magn Reson Med 74:13-24, 2015. (c) 2014 Wiley Periodicals, Inc.

TI Teaching during consultation: factors affecting the resident-fellow

SO MEDICAL EDUCATION
LA English
DT Article
ID EMERGENCY-DEPARTMENT; QUALITATIVE DATA; COMMUNICATION; FRAMEWORK
AB ObjectivesThe subspecialty consultation represents a potentially powerful opportunity for resident learning, but barriers may limit the educational exchanges between fellows (subspecialty registrars) and residents (house officers). We conducted a focus group study of internal medicine (IM) residents and subspecialty fellows to determine barriers against and factors facilitating resident-fellow teaching interactions on the wards, and to identify opportunities for maximising teaching and learning.
MethodsWe conducted four focus groups of IM residents (n=18) and IM subspecialty fellows (n=16) at two academic medical centres in the USA during February and March 2013. Participants represented trainees in all 3years of residency training and seven IM subspecialties. Four investigators analysed the transcripts using a structured qualitative framework approach, which was informed by literature on consultation and the theoretical framework of activity theory.
ResultsWe identified two domains of barriers and facilitating factors: personal and systems-based. Sub-themes in the personal domain included fellows' perceived resistance to consultations, residents' willingness to engage in teaching interactions, and perceptions and expectations. Sub-themes in the systems-based domain included the process of requesting the consult, the quality of the consult request, primary team structure, familiarity between residents and fellows, workload, work experience, culture of subspecialty divisions, and fellows' teaching skills. These barriers differentially affected the two stages of the consult identified in the focus groups (initial interaction and follow-up interaction).
ConclusionsResidents and fellows want to engage in positive teaching interactions in the context of the clinical consult; however, multiple barriers influence both parties in the hospital environment. Many of these barriers are amenable to change. Interventions aimed at reducing barriers to teaching in the setting of consultation hold promise for improving teaching and learning on the wards.

AB Intuition suggests that perception follows sensation and therefore bodily feelings originate in the body. However, recent evidence goes against this logic: interoceptive experience may largely reflect limbic predictions about the expected state of the body that are constrained by ascending visceral sensations. In this Opinion article, we introduce the Embodied Predictive Interoception Coding model, which integrates an anatomical model of corticocortical connections with Bayesian active inference principles, to propose that agranular visceromotor cortices contribute to interoception by issuing interoceptive predictions. We then discuss how disruptions in interoceptive predictions could function as a common vulnerability for mental and physical illness.

AB Major depressive disorder (MDD) and nicotine dependence are highly comorbid, with studies showing that similar to 50% of individuals with MDD smoke. The link between these disorders persists even after the clinical symptoms of depression subside, as indicated by high levels of nicotine dependence among individuals with remitted depression (rMDD). Recent evidence indicates that individuals with rMDD show blunted responses to reward as measured by a probabilistic reward task (PRT), which assesses the ability to modify behavior as a function of reward history. Given nicotine's ability to enhance reward responsiveness, individuals with rMDD might smoke to address this persistent reward deficit. However, it is unclear whether smokers with rMDD show enhanced reward responsiveness relative to rMDD individuals who do not smoke. To test this hypothesis, we evaluated reward responsiveness on the PRT in four groups (N = 198): individuals with and without rMDD who were or were not nicotine dependent. As hypothesized, rMDD nonsmokers had lower reward responsiveness relative to both control nonsmokers and rMDD smokers; conversely, smokers with rMDD showed behavioral patterns comparable to those without a history of depression. Given nicotine's ability to enhance reward sensitivity, it is possible that nicotine normalizes the otherwise blunted reward responsiveness in individuals with rMDD. Therapies aimed at enhancing this reward-based deficit may be beneficial in the treatment of both nicotine dependence and MDD.

TI Computer-aided analyses of mouse retinal OCT images - an actual

DE image segmentation; mouse study; optical coherence tomography;
photoreceptor degeneration
ID OPTICAL COHERENCE TOMOGRAPHY; SEGMENTATION; LAYERS
AB PurposeThere is a need for automated retinal optical coherence tomography (OCT) image analysis tools for quantitative measurements in small animals. Some image processing techniques for retinal layer analysis have been developed, but reports about how useful those techniques are in actual animal studies are rare. This paper presents the use of a retinal layer detection method we developed in an actual mouse study that involves wild type and mutated mice carrying photoreceptor degeneration.
MethodsSpectral domain OCT scanning was performed by four experimenters over 12months on 45 mouse eyes that were wild-type, deficient for ephrin-A2 and ephrin-A3, deficient for rhodopsin, or deficient for rhodopsin, ephrin-A2 and ephrin-A3. The thickness of photoreceptor complex between the outer plexiform layer and retinal pigment epithelium was measured on two sides of the optic disc as the biomarker of retinal degeneration. All the layer detection results were visually confirmed.
ResultsOverall, 96% (8519 out of 9000) of the half-side images were successfully processed using our technique in a semi-automatic manner. There was no significant difference in success rate between mouse lines (p=0.91). Based on a human observer's rating of image quality for images successfully and unsuccessfully processed, the odds ratios for easily visible' images and not clear' images to be successfully processed is 62 and 4, respectively, against indistinguishable' images. Thickness of photoreceptor complex was significantly different across the quadrants compared (p<0.001). It was also found that the average thickness based on 4-point sparse sampling was not significantly different from the full analysis, while the range of differences between the two methods could be up to about 6m or 16% for individual eyes. Differences between mouse lines and progressive thickness reduction were revealed by both sampling measures.
ConclusionsAlthough the thickness of the photoreceptor complex layer is not even, manual sparse sampling may be as sufficiently accurate as full analysis in some studies such as ours, where the error of sparse sampling was much smaller than the effect size of rhodopsin deficiency. It is also suggested that the image processing method can be useful in actual animal studies. Even for images poorly visible to human eyes the image processing method still has a good chance to extract the complex layer.

AB Objective: In patients with knee OA, synovitis is associated with knee pain and symptoms. We previously identified synovial mRNA expression of a set of chemokines (CCL19, IL-8, CCL5, XCL-1, CCR7) associated with synovitis in patients with meniscal tears but without radiographic OA. CCL19 and CCR7 were also associated with knee symptoms. This study sought to validate expression of these chemokines and association with knee symptoms in more typical patients presenting for meniscal arthroscopy, many who have pre-existing OA.
Design: Synovial fluid (SF) and biopsies were collected from patients undergoing meniscal arthroscopy. Synovial mRNA expression was measured using quantitative RT-PCR. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was administered preoperatively. Regression analyses determined if associations between chemokine mRNA levels and KOOS scores were independent of other factors including radiographic OA. CCL19 in SF was measured by ELISA, and compared to patients with advanced knee OA and asymptomatic organ donors.
Results: 90% of patients had intra-operative evidence of early cartilage degeneration. CCL19, IL-8, CCL5, XCL1, CCR7 transcripts were detected in all patients. Synovial CCL19 mRNA levels independently correlated with KOOS Activities of Daily Living (ADL) scores (95% CI [-8.071, -0.331], P = 0.036), indicating higher expression was associated with more knee-related dysfunction. SF CCL19 was detected in 7 of 10 patients, compared to 4 of 10 asymptomatic donors.
Conclusion: In typical patients presenting for meniscal arthroscopy, synovial CCL19 mRNA expression was associated with knee-related difficulty with ADL, independent of other factors including presence of radiographic knee OA.

AB Objective: In growth plate chondrocytes, loss of Dicer, a microRNA (miRNA)-processing enzyme, causes defects in proliferation and differentiation, leading to a lethal skeletal dysplasia. However roles of miRNAs in articular chondrocytes have not been defined in vivo. To investigate the role of miRNAs in articular chondrocytes and to explore the possibility of generating a novel mouse osteoarthritis (OA) model caused by intrinsic cellular dysfunction, we ablated Drosha, another essential enzyme for miRNA biogenesis, exclusively in articular chondrocytes of postnatal mice.
Design: First, to confirm that the essential role of miRNAs in skeletal development, we ablated the miRNA biogenesis pathway by deleting Drosha or DGCR8 in growth plate chondrocytes. Next, to investigate the role of miRNAs in articular cartilage, we deleted Drosha using Prg4-CreERT transgenic mice expressing a tamoxifen-activated Cre recombinase (CreERT) exclusively in articular chondrocytes. Tamoxifen was injected at postnatal days, 7, 14, 21, and 28 to ablate Drosha.
Results: Deletion of Drosha or DGCR8 in growth plate chondrocytes caused a lethal skeletal defect similar to that of Dicer deletion, confirming the essential role of miRNAs in normal skeletogenesis. Early postnatal Drosha deletion in articular chondrocytes significantly increased cell death and decreased SafraninO staining. Mild OA-like changes, including surface erosion and cleft formation, were found in male mice at 6 months of age; however such changes in females were not observed even at 9 months of age.
Conclusions: Early postnatal Drosha deficiency induces articular chondrocyte death and can cause a mild OA-like pathology. (C) 2015 Osteoarthritis Research Society International. Published by Elsevier Ltd. All rights reserved.

AB Purpose: To develop and test the suitability and performance of a comprehensive quality assurance (QA) phantom for the Small Animal Radiation Research Platform (SARRP).
Methods and materials: A QA phantom was developed for carrying out daily, monthly and annual QA tasks including: imaging, dosimetry and treatment planning system (TPS) performance evaluation of the SARRP. The QA phantom consists of 15 (60 x 60 x 5 mm(3)) kV-energy tissue equivalent solid water slabs. The phantom can incorporate optically stimulated luminescence dosimeters (OSLD), Mosfet or film. One slab, with inserts and another slab with hole patterns are particularly designed for image QA.
Results: Output constancy measurement results showed daily variations within 3%. Using the Mosfet in phantom as target, results showed that the difference between TPS calculations and measurements was within 5%. Annual QA results for the Percentage depth dose (PDD) curves, lateral beam profiles, beam flatness and beam profile symmetry were found consistent with results obtained at commissioning. PDD curves obtained using film and OSLDs showed good agreement. Image QA was performed monthly, with image-quality parameters assessed in terms of CBCT image geometric accuracy, CT number accuracy, image spatial resolution, noise and image uniformity.
Conclusions: The results show that the developed QA phantom can be employed as a tool for comprehensive performance evaluation of the SARRP. The study provides a useful reference for development of a comprehensive quality assurance program for the SARRP and other similar small animal irradiators, with proposed tolerances and frequency of required tests.

AB Background: As systems care become more complex and comorbid medical and psychiatric illness becomes more evident, it is essential to prepare psychiatric trainees for practice in more integrated models of care. Objective: We sought to identify readings available for residency training in consultation-liaison C-L) psychiatry/psychosomatic medicine with the intent to help educators and trainees identify appropriate and essential learning resources within the field. Methods: We reviewed readings available to the residents (including commonly used textbooks in C-L psychiatry and C-L training programs' required reading lists') and identified areas of consensus regarding the topics germane to the care of patients with comorbid medical and psychiatric illness (namely depression, dementia, and delirium) and the education of trainees. Results: There was considerable variation in the references cited by well-regarded textbooks and by reading lists created for trainees in C-L psychiatry. In the 4 textbooks reviewed, there were 83 shared citations on delirium (including 10 citations that were common to all 4 textbooks and 17 citations shared by 3 textbooks.). Markedly less overlap was noted in the chapters on depression (only 2 references cited in all of the textbooks with relevant content) and dementia (only 7 shared references). Conclusion: Given the paucity of overlap of citations in commonly used textbooks., we recommend that practical topical reviews or textbook chapters be used as core (required) or recommended readings for residents on C-L psychiatry rotations, supplemented by a small number of studies or case series that illustrate key tea lung points on each essential topic.

AB Background: Illness (symptoms and disability) consistently correlates more with coping strategies and symptoms of depression than with pathophysiology or impairment. Objective: This study tested the primary null hypothesis that there is no correlation between verbal and nonverbal communication of pain (pain behavior) and upper extremity specific disability in patients with hand and upper extremity illness. Methods: A total of 139 new and followed up adult patients completed the QuickDASH, an ordinal rating of pain, and 4 Patient-Reported Outcomes Measurement Information System (PROMIS) Computer Adaptive Testing instruments: (PROMIS pain behavior, (2) PROMIS pain interference (measuring the degree to which pain interferes with achieving ones physical goals), (3) PROIVIIS physical function., and (4) PROMIS depression. Results: Factors associated with a higher QuickDASH score in bivariate analysis included a higher PROMIS pain behavior score, not working, being separated/divorced or widowed, having sought treatment before, having other pain conditions, a higher PROMIS pain interference score, a higher PROMIS depression score, and lower education level. The final multivariable model of factors' associated with QuickDASH included PROMIS pain interference, having other pain conditions, and being separated/divorced or widowed, and it explained 64% of the variability. Conclusion: PROMIS pain behavior (verbal and nonverbal communication of pain) correlates with upper extremity disability, but PROMIS pain interference (the degree to which pain interferes with activity) is a more important,factor. Level of Evidence: Level IV cross-sectional study.

AB Salivary gland tumors (SGT) are notorious for their extraordinary diversity and for the morphological overlap that exists between many of these entities. Fine-needle aspiration biopsy (FNAB) has a well-established role in the evaluation of patients with a salivary gland lesion, helping to guide clinical management. However, salivary gland FNAB has several limitations and does not allow for a specific diagnosis in some cases. For these reasons, salivary gland FNAB is considered one of the most challenging areas in cytopathology. Over the last decade, new salivary gland entities have been recognized, enlarging SGT diversity and complexity even more. In addition, a subset of SGT, including common entities such as pleomorphic adenoma and uncommon new entities such as mammary analog secretory carcinoma, have been characterized cytogenetically by the presence of specific translocations. The molecular consequences of these translocations and their potential prognostic and therapeutic values are not yet well characterized. However, these translocations and their resulting fusion oncogenes and oncoproteins can be used as diagnostic clues in salivary gland FNAB material in order to overcome the limitations of cytomorphological evaluation alone. In this review, we focus on SGTs currently known to harbor translocations and fusion genes, including uncommon and recently recognized entities, and discuss their potential application to salivary gland FNAB.

TI Hydrogen Peroxide-Producing Lactobacilli Are Associated With Lower

SO SEXUALLY TRANSMITTED DISEASES
LA English
DT Article
ID IMMUNODEFICIENCY-VIRUS TYPE-1; PRETERM DELIVERY; GENITAL-TRACT;
IN-VITRO; BIRTH; INFLAMMATION; INFECTION; WOMEN; COLONIZATION; FLUID
AB Background
The presence of hydrogen peroxide (H2O2)-producing lactobacilli in the vagina is associated with decreased rates of preterm birth and HIV acquisition. We hypothesize that this is due to immunomodulatory effects of these species.
Methods
Concentrations of interleukin (IL)-1 beta, IL-6, IL-8, secretory leukocyte protease inhibitor, and human beta-defensin 2 were quantified from vaginal swabs from 4 groups of women: women with and without bacterial vaginosis (BV) by Nugent score, further stratified by detection of H2O2-producing lactobacilli by semiquantitative culture. Ten quantitative polymerase chain reaction assays characterized the presence and quantity of select Lactobacillus and BV-associated species in each group. Levels of immune markers and bacteria were compared between the 4 groups using analysis of variance, Kruskal-Wallis, Mann-Whitney U, or chi(2) tests.
Results
Swabs from 110 women from 4 groups were included: 26 had a normal Nugent score (BV-), and no H2O2-producing lactobacilli detected (H2O2-); 47 were BV-, H2O2+; 27 BV+, H2O2-; and 10 BV+, H2O2+. The groups were similar in age, marital status, and reproductive history, but not ethnicity: the BV-, H2O2- group had more white participants (P = 0.02). In women with and without BV, IL-1 beta was lower in the H2O2+ groups. Human beta-defensin 2 was lowest in BV+ H2O2- women and highest in BV-, H2O2-. Secretory leukocyte protease inhibitor was lower in women with BV and did not differ by the presence of H2O2-producing lactobacilli. In regression analysis, higher quantities of Lactobacillus crispatus were associated with lower quantities of IL-1 beta. Detection and quantity of BV-associated species by quantitative polymerase chain reaction was significantly different between women with and without BV, but not between women with and without H2O2-producing lactobacilli within those groups.
Conclusions
The presence of H2O2-producing lactobacilli is associated with lower levels of some vaginal proinflammatory cytokines, even in women with BV.

PATHOLOGY
AB BACKGROUND CONTEXT: Previous studies have reported position-dependent changes of the lumbar intervertebral foramen (LIVF) dimensions at different static flexion-extension postures. However, the changes of the LIVF dimensions during dynamic body motion have not been reported.
PURPOSE: The objective of this study was to investigate the in vivo dimensions of the LIVF during a dynamic weight-lifting activity.
STUDY DESIGN/SETTING: This was a retrospective study.
METHODS: Ten asymptomatic subjects were recruited for this study. Three-dimensional (3D) vertebral models of the lumbar segments from L2 to S1 were constructed for each subject using magnetic resonance images. The lumbar spine was then imaged using a dual fluoroscopic imaging system as the subject performed a dynamic weight-lifting activity from an upper body position of 45 degrees to a maximal extension position. The in vivo positions of the vertebrae along the motion path were reproduced using the 3D vertebral models and the fluoroscopic images. The minimal area, height, and width of each LIVF during the dynamic body motion were analyzed.
RESULTS: The LIVF area and width monotonically decreased with lumbar extension at all levels except L5-S1 (p<05). On average, the LIVF area decreased by 7.4 +/- 6.7%, 10.8 +/- 7.7%, and 10.068.0% at the L2-L3, L3-L4, and L4-L5 levels, respectively, from the flexion to the upright standing position, and by 6.4 +/- 5.0%, 7.7 +/- 7.4%, and 5.1 +/- 5.1%, respectively, from the upright standing to the extension position. The LIVF height remained relatively constant at all segments during the dynamic activity. The foramen area, height, and width of the L5-S1 remained relatively constant throughout the activity.
CONCLUSIONS: Human lumbar foramen dimensions show segment-dependent characteristics during the dynamic weight-lifting activity. (C) 2015 Elsevier Inc. All rights reserved.

TI Half a billion surgical cases: Aligning surgical delivery with
best-performing health systems
SO SURGERY
LA English
DT Article
ID CLEFT-LIP; SURGERY; BURDEN; PALATE; CARE
AB Background. Surgical delivery varies 200-fold across countries. No direct correlation exists, however, between surgical delivery and health outcomes, making it difficult to pinpoint a goal for surgical scale-up. This report determines the amount of surgery that would be delivered worldwide if the world aligned itself with countries providing the best health outcomes.
Methods. Annual rates of surgical delivery have been published previously for 129 countries. Five health outcomes were plotted against reported surgical delivery. Univariate and multivariate polynomial regression curves were fit, and the optimal point on each regression curve was determined by solving for first-order conditions. The country closest to the optimum for each health outcome was taken as representative of the best-performing health system. Monetary inputs to and surgical procedures provided by these systems were scaled to the global population.
Results. For 3 of the 5 health outcomes, optima could be found. Globally, 315 million procedures currently are provided annually. If global delivery mirrored the 3 best-performing countries, between 360 million and 460 million cases would be provided annually. With population growth, this will increase to approximately half a billion cases by 2030. Health systems delivering these outcomes spend approximately 10% of their GDP on health.
Conclusion. This is the first study to provide empirical evidence for the surgical output that an ideal health system would provide. Our results project ideal delivery worldwide of approximately 550 million annual surgical cases by 2030.

AB Background. The impact of diaphragmatic invasion in patients with colorectal liver metastases (CRLMs) remains poorly evaluated. We aimed to evaluate feasibility and safety of laparoscopic right hepatectomy (LRH) with or without diaphragmatic resection for CRLM.
Methods. From 2002 to 2012, 52 patients underwent LRH for CRLM. Of them, 7 patients had combined laparoscopic partial diaphragmatic resection ("diaphragm" group). Data were retrospectively collected and short and long-term outcomes analyzed.
Results. Operative time was lower in the control group (272 vs 345 min, P = .06). Six patients required conversion to open surgery. Blood loss and transfusion rate were similar. Portal triad clamping was used more frequently in the "diaphragm" group (42.8% vs 6.6%, P = .02). Maximum tumor size was greater in the "diaphragm" group (74.5 vs 37.1 mm, P = .002). Resection margin was negative in all cases. Mortality was nil and general morbidity similar in the 2 groups. Specific liver-related complications occurred in 2 patients in the "diaphragm" group and 17 in the control group (P = .69). Mean hospital stay was similar (P = 56). Twenty-two (42.3%) patients experienced recurrence. One-, 3-, and 5-year overall survival after surgery in "diaphragm" and control groups were 69%, 34%, 34%, and 97%, 83%, 59%, respectively (P = .103). One- and 3-year disease-free survival after surgery in "diaphragm" and control groups were 57%, 47% and 75%, 54%, respectively (P = .310).
Conclusion. LRH with en-bloc diaphragmatic resection could be reasonably performed for selected patients in expert centers. Technical difficulties related to diaphragmatic invasion must be circumvented. Further experience must be gained to confirm our results.

AB In November 2014, a 3-day conference devoted to transfusion medicine in sub-Saharan Africa was held in Kampala, Uganda. Faculty from academic institutions in Uganda provided a broad overview of issues pertinent to transfusion medicine in Africa. The conference consisted of lectures, demonstrations, and discussions followed by 5 small group workshops held at the Uganda Blood Transfusion Service Laboratories, the Ugandan Cancer Institute, and the Mulago National Referral Hospital. Highlighted topics included the challenges posed by increasing clinical demands for blood, the need for better patient identification at the time of transfusion, inadequate application of the antiglobulin reagent during pretransfusion testing, concern regarding proper recognition and evaluation of transfusion reactions, the expanded role for nurse leadership as a means to improve patient outcomes, and the need for an epidemiologic map of blood usage in Africa. Specialty areas of focus included the potential for broader application of transcranial Doppler and hydroxyurea therapy in sickle cell disease, African-specific guidelines for transfusion support of cancer patients, the challenges of transfusion support in trauma, and the importance of African-centered clinical research in pediatric and obstetric transfusion medicine. The course concluded by summarizing the benefits derived from an organized quality program that extended from the donor to the recipient As an educational tool, the slide-audio presentation of the lectures will be made freely available at the International Society of Blood Transfusion Academy Web site: http://www.isbtweb.org/academy/.

AB Vestibular schwannomas (VSs) are the most common tumors of the cerebellopontine angle. Significant clinical need exists for pharmacotherapies against VSs. Motivated by previous findings that immunohistochemical expression of cyclooxygenase 2 (COX-2) correlates with VS growth rate, we investigated the role of COX-2 in VSs and tested COX-2 inhibiting salicylates against VSs. COX-2 was found to be aberrantly expressed in human VS and primary human VS cells in comparison with control human nerve specimens and primary Schwann cells (SCs), respectively. Furthermore, levels of prostaglandin E2, the downstream enzymatic product of COX-2, were correlated with primary VS culture proliferation rate. Because COX-2 inhibiting salicylates such as aspirin are well tolerated and frequently clinically used, we assessed their repurposing for VS. Changes in proliferation, cell death, and cell viability were analyzed in primary VS cultures treated with aspirin, sodium salicylate, or 5-aminosalicylic acid. These drugs neither increased VS cell death nor affected healthy SCs. The cytostatic effect of aspirin in vitro was in concurrence with our previous clinical finding that patients with VS taking aspirin demonstrate reduced tumor growth. Overall, this work suggests that COX-2 is a key modulator in VS cell proliferation and survival and highlights salicylates as promising pharmacotherapies against VS.

AB Rho kinase mediates the effects of inflammatory permeability factors by increasing actomyosin-generated traction forces on endothelial adherens junctions, resulting in disassembly of intercellular junctions and increased vascular leakage. In vitro, this is accompanied by the Rho kinase-driven formation of prominent radial F-actin fibers, but the in vivo relevance of those F-actin fibers has been debated, suggesting other Rho kinase-mediated events to occur in vascular leak. Here, we delineated the contributions of the highly homologous isoforms of Rho kinase (ROCK1 and ROCK2) to vascular hyperpermeability responses. We show that ROCK2, rather than ROCK1 is the critical Rho kinase for regulation of thrombin receptor-mediated vascular permeability. Novel traction force mapping in endothelial monolayers, however, shows that ROCK2 is not required for the thrombin-induced force enhancements. Rather, ROM is pivotal to baseline junctional tension as a novel mechanism by which Rho kinase primes the endothelium for hyperpermeability responses, independent from subsequent ROCK1-mediated contractile stress-fiber formation during the late phase of the permeability response.

AB Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with repetitive mild traumatic brain injury. It is defined pathologically by the abnormal accumulation of tau in a unique pattern that is distinct from other tauopathies, including Alzheimer's disease (AD). Although trauma has been suggested to increase amyloid beta peptide (A beta) levels, the extent of A beta deposition in CTE has not been thoroughly characterized. We studied a heterogeneous cohort of deceased athletes and military veterans with neuropathologically diagnosed CTE (n = 114, mean age at death = 60) to test the hypothesis that A beta deposition is altered in CTE and associated with more severe pathology and worse clinical outcomes. We found that A beta deposition, either as diffuse or neuritic plaques, was present in 52 % of CTE subjects. Moreover, A beta deposition in CTE occurred at an accelerated rate and with altered dynamics in CTE compared to a normal aging population (OR = 3.8, p < 0.001). We also found a clear pathological and clinical dichotomy between those CTE cases with A beta plaques and those without. A beta deposition was significantly associated with the presence of the APOE epsilon 4 allele (p = 0.035), older age at symptom onset (p < 0.001), and older age at death (p < 0.001). In addition, when controlling for age, neuritic plaques were significantly associated with increased CTE tauopathy stage (beta = 2.43, p = 0.018), co-morbid Lewy body disease (OR = 5.01, p = 0.009), and dementia (OR = 4.45, p = 0.012). A subset of subjects met the diagnostic criteria for both CTE and AD, and in these subjects both A beta plaques and total levels of A beta 1-40 were increased at the depths of the cortical sulcus compared to the gyral crests. Overall, these findings suggest that A beta deposition is altered and accelerated in a cohort of CTE subjects compared to normal aging and that A beta is associated with both pathological and clinical progression of CTE independent of age.

AB Genetic factors appear to be highly relevant to predicting differential risk for the development of post-traumatic stress disorder (PTSD). In a discovery sample, we conducted a genome-wide association study (GWAS) for PTSD using a small military cohort (Systems Biology PTSD Biomarkers Consortium; SBPBC, N=147) that was designed as a case-controlled sample of highly exposed, recently returning veterans with and without combat-related PTSD. A genome-wide significant single nucleotide polymorphism (SNP), rs717947, at chromosome 4p15 (N=147, =31.34, P=1.28x10(-8)) was found to associate with the gold-standard diagnostic measure for PTSD (the Clinician Administered PTSD Scale). We conducted replication and follow-up studies in an external sample, a larger urban community cohort (Grady Trauma Project, GTP, N=2006), to determine the robustness and putative functionality of this risk variant. In the GTP replication sample, SNP rs717947 associated with PTSD diagnosis in females (N=2006, P=0.005), but not males. SNP rs717947 was also found to be a methylation quantitative trait locus (meQTL) in the GTP replication sample (N=157, P=0.002). Further, the risk allele of rs717947 was associated with decreased medial and dorsolateral cortical activation to fearful faces (N=53, P<0.05) in the GTP replication sample. These data identify a genome-wide significant polymorphism conferring risk for PTSD, which was associated with differential epigenetic regulation and with differential cortical responses to fear in a replication sample. These results may provide new insight into understanding genetic and epigenetic regulation of PTSD and intermediate phenotypes that contribute to this disorder. (c) 2015 Wiley Periodicals, Inc.

AB BACKGROUND: Increased sensitivity to stress and dysfunctional reward processing are two primary characteristics of major depressive disorder (MDD) that may persist after remission. Preclinical work has established the pivotal role of the striatum in mediating both stress and reward responses. Human neuroimaging studies have corroborated these preclinical findings and highlighted striatal dysfunction in MDD in response to reward but have yet to investigate striatal function during stress, in particular in individuals with recurrent depression.
METHODS: A validated mild psychological stress task involving viewing of negative stimuli during functional magnetic resonance imaging was conducted in 33 remitted individuals with a history of recurrent major depressive disorder (rMDD) and 35 matched healthy control subjects. Cortisol and anxiety levels were assessed throughout scanning. Stress-related activation was investigated in three striatal regions: caudate, nucleus accumbens, and putamen. Psychophysiologic interaction analyses probed connectivity of regions with central structures of the neural stress circuitry, such as the amygdala and hippocampus.
RESULTS: The task increased cortisol and anxiety levels, although to a greater extent in rMDD individuals than healthy control subjects. In response to the negative stimuli, rMDD individuals, but not controls, also exhibited significantly potentiated caudate, nucleus accumbens, and putamen activations and increased caudate-amygdala and caudate-hippocampus connectivity.
CONCLUSIONS: The findings highlight striatal hypersensitivity in response to a mild psychological stress in rMDD, as manifested by hyperactivation and hyperconnectivity with the amygdala and hippocampus. Striatal hypersensitivity during stress might thus constitute a trait mark of depression, providing a potential neural substrate for the interaction between stress and reward dysfunction in MDD.

AB We investigated whether increasing size of lymph nodes (LN) metastases is associated with lower breast cancer-specific survival (BCSS) and overall survival (OS) independent of the number of positive LNs. Using Surveillance, Epidemiology, and End Results registry data, we identified 8791 women diagnosed between 1990 and 2003 with node-positive, non-metastatic invasive breast cancer treated with surgery and axillary LN dissection. Size of the largest involved LN metastasis was categorized as a parts per thousand currency sign2 mm, > 2 mm to < 2 cm, and a parts per thousand yen2 cm. BCSS and OS were estimated using the Kaplan-Meier method and compared using log-rank statistics. Adjusted hazard ratios (HR) were calculated using Cox proportional hazards models. Median follow-up was 109 months. Largest LN size was a parts per thousand currency sign2 mm, > 2 mm to < 2 cm, and a parts per thousand yen2 cm in 2219 (25.2 %), 5047 (57.4 %), and 1525 (17.3 %) women, respectively. The 10-year BCSS for women with LNs a parts per thousand currency sign2 mm, > 2 mm to < 2 cm, and a parts per thousand yen2 cm was 82.9, 75.5, 64.8 %, respectively (p < 0.001). On multivariable analysis, large (a parts per thousand yen2 cm) LN size was significantly associated with worsened BCSS (HR: 1.169; p = 0.026) and OS (HR: 1.169; p = 0.006) in addition to age, race, grade, PR status, adjuvant radiation, T-stage, and number of positive LNs. Large (a parts per thousand yen2 cm) LNs metastases were associated with lower BCSS and OS after controlling for other known prognostic factors including number of positive LNs. LN size could be useful to risk-stratify patients for adjuvant therapy if these results are validated in future prospective studies.

AB Disease classification system increasingly incorporates information on pathogenic mechanisms to predict clinical outcomes and response to therapy and intervention. Technological advancements to interrogate omics (genomics, epigenomics, transcriptomics, proteomics, metabolomics, metagenomics, interactomics, etc.) provide widely open opportunities in population-based research. Molecular pathological epidemiology (MPE) represents integrative science of molecular pathology and epidemiology. This unified paradigm requires multidisciplinary collaboration between pathology, epidemiology, biostatistics, bioinformatics, and computational biology. Integration of these fields enables better understanding of etiologic heterogeneity, disease continuum, causal inference, and the impact of environment, diet, lifestyle, host factors (including genetics and immunity), and their interactions on disease evolution. Hence, the Second International MPE Meeting was held in Boston in December 2014, with aims to: (1) develop conceptual and practical frameworks; (2) cultivate and expand opportunities; (3) address challenges; and (4) initiate the effort of specifying guidelines for MPE. The meeting mainly consisted of presentations of method developments and recent data in various malignant neoplasms and tumors (breast, prostate, ovarian and colorectal cancers, renal cell carcinoma, lymphoma, and leukemia), followed by open discussion sessions on challenges and future plans. In particular, we recognized need for efforts to further develop statistical methodologies. This meeting provided an unprecedented opportunity for interdisciplinary collaboration, consistent with the purposes of the Big Data to Knowledge, Genetic Associations and Mechanisms in Oncology, and Precision Medicine Initiative of the US National Institute of Health. The MPE meeting series can help advance transdisciplinary population science and optimize training and education systems for twenty-first century medicine and public health.

AB High glucose milieu inhibits PTEN expression to activate Akt kinase and induces glomerular mesangial cell hypertrophy and matrix protein expression in diabetic nephropathy. Specific mechanism by which high glucose inhibits PTEN expression is not clear. We found that high glucose increased the expression of the microRNA-26a (miR-26a) in mesangial cells. Using a sensor plasmid with 3'UTR-driven luciferase, we showed PTEN as a target of miR-26a in response to high glucose. Overexpression of miR-26a reduced the PTEN protein levels resulting in increased Akt kinase activity similar to high glucose treatment. In contrast, anti-miR-26a reversed high glucose-induced suppression of PTEN with concomitant inhibition of Akt kinase activity. Akt-mediated phosphorylation of tuberin and PRAS40 regulates mTORC1, which is necessary for mesangial cell hypertrophy and matrix protein expression. Inhibition of high glucose-induced miR-26a blocked phosphorylation of tuberin and PRAS40, which lead to suppression of phosphorylation of S6 kinase and 4EBP-1, two substrates of mTORC1. Furthermore, we show that expression of miR-26a induced mesangial cell hypertrophy and increased fibronectin and collagen I (alpha 2) expression similar to that observed with the cells incubated with high glucose. Anti-miR-26a inhibited these phenomena in response to high glucose. Together our results provide the first evidence for the involvement of miR-26a in high glucose-induced mesangial cell hypertrophy and matrix protein expression. These data indicate the potential therapeutic utility of anti-miR-26a for the complications of diabetic kidney disease. Published by Elsevier Inc.

TI A History of Treated Periprosthetic Joint Infection Increases the Risk
of Subsequent Different Site Infection
SO CLINICAL ORTHOPAEDICS AND RELATED RESEARCH

DT Article
ID TOTAL KNEE ARTHROPLASTY; MORTALITY
AB After the successful treatment of periprosthetic joint infection (PJI), patients may present with degenerative joint disease in another joint with symptoms severe enough to warrant arthroplasty. However, it is not known whether patients with a history of treated PJI at one site will have an increased risk of PJI in the second arthroplasty site.
The primary objective of this study is to determine if there is a difference in the risk of developing a PJI after a second total hip arthroplasty (THA) or total knee arthroplasty (TKA) in patients who have had a previous PJI at another anatomic site compared with patients who have had no history of PJI. The secondary objective is to determine other potential risk factors that may predict PJI at the site of the second arthroplasty.
A retrospective matched cohort study was performed to identify all patients at four academic institutions successfully treated for PJI who subsequently underwent a second primary THA or TKA (n = 90), constituting our study group. Patients were matched (one-to-one) to control subjects who had no history of PJI after their first arthroplasty (n = 90); they were matched based on age, sex, diabetic status, BMI, American Society of Anesthesiologists, institution, joint of interest, and year of surgery (+/- A 2 years). We compared the case and control groups to determine whether a prior infection increased the relative risk of a subsequent PJI at another anatomic site. To identify other potential risk factors for subsequent PJI, a subgroup univariate analysis of our study group (n = 90) was performed. To identify other potential risk factors for subsequent PJI, a subgroup univariate analysis of our study group (n = 90) was performed.
Patients with a history of PJI had a greater risk of developing PJI in a subsequent THA or TKA (10 of 90 versus zero of 90 in the control group; relative risk, 21.00; 95% confidence interval [CI], 1.25-353.08; p = 0.035). Excluding PJI, we identified no other factors associated with a second joint infection. In patients with a history of PJI, a second PJI occurred more frequently in female patients (female: nine of 10 [90%] versus female: 40 of 80 [50%]; odds ratio [OR], 8.83; 95% CI, 1.13-403.33; p = 0.02) and in those whose initial infection was a staphylococcal species (subsequent PJI seven of 10 [70%] versus no subsequent PJI 28 of 80 [35%]; OR, 4.26; 95% CI, 0.89-27.50; p = 0.04).
A history of PJI predisposes patients to subsequent PJI in primary THA or THA. Patients and surgeons must be aware of the higher risk of this devastating complication before proceeding with a second arthroplasty.

TI Are Allogeneic Blood Transfusions Associated With Decreased Survival
After Surgery for Long-bone Metastatic Fractures?
SO CLINICAL ORTHOPAEDICS AND RELATED RESEARCH

DT Article

COLORECTAL-CANCER; DISEASE; RISK; MORBIDITY
AB Previous studies have shown that perioperative blood transfusion increases cancer recurrence and decreases patient survival after resection of primary malignancies. The question arises whether this association also exists in patients with already disseminated disease undergoing surgery for metastatic long-bone fractures.
We sought to determine whether perioperative allogeneic blood transfusion is associated with decreased survival after operative treatment of long-bone metastatic fractures after accounting for clinical, laboratory, and treatment factors. Secondarily, we aimed to identify potential factors that are associated with decreased survival.
We included 789 patients in our retrospective study who underwent surgery at two institutions for a pathologic or impending metastatic long-bone fracture. We used multivariable Cox proportional hazards regression model analysis to assess the relationship of perioperative allogeneic blood transfusion with survival, and accounted for patient age, sex, comorbidities, BMI, tumor type, fracture type and location, presence of other bone and visceral metastases, previous radiotherapy and systemic therapy, preoperative embolization, preoperative hemoglobin level, treatment type, anesthesia time, blood loss, duration of hospital admission, year of surgery, and hospital.
Considering transfusion as an "exposure," and comparing patients who received transfusions with those who did not, we found that blood transfusion was not associated with decreased survival after accounting for all explanatory variables (hazard ratio [HR] 1.06; 95% CI, 0.87-1.30; p = 0.57). Evaluating transfusion in terms of dose-response, we found that patients who received more transfusions had lower survival compared with those who had fewer transfusions after accounting for all explanatory variables (HR per unit of blood transfused, 1.07; 95% CI, 1.02-1.12; p = 0.005). We found that age (HR, 1.02; 95% CI, 1.01-1.02; p < 0.001), comorbidity status (HR, 1.06; 95% CI, 1.01-1.10; p = 0.014), duration of hospital stay (HR, 1.02; 95% CI 1.00-1.03; p = 0.021), tumor type (HR, 1.71; 95% CI, 1.44-2.03; p < 0.001), and visceral metastases (HR, 1.59; 95% CI, 1.34-1.88; p < 0.001) were independently associated with survival.
We found that exposure to perioperative allogeneic blood transfusion does not decrease survival, with the numbers available. However, our sample size might have been insufficient to reveal a small but potentially relevant effect. Our results do suggest a dose-response relationship; patients who received more transfusions had lower survival compared with those with fewer transfusions. Risk of death increased by 7% per unit of blood transfused.

TI Time Seeing a Hand Surgeon Is Not Associated With Patient Satisfaction

ID PRIMARY-CARE; ITEM BANK; OUTCOMES; DEPRESSION; HEALTH; PHYSICIAN;
EXTREMITY
AB Previous studies, predominantly in the primary care setting, identified time spent with the physician as an important predictor of satisfaction. It is unknown if the same holds true in hand surgery.
Is patient satisfaction measured immediately after an office visit associated with the duration of time spent with the hand surgeon? What other factors are associated with satisfaction directly after the visits and 2 weeks after the appointment?
We prospectively enrolled 81 patients visiting our hand and upper extremity surgery outpatient clinic. We recorded their demographics and measured physical function, pain behavior, symptoms of depression, time spent in the waiting room, time spent with the physician, and patient satisfaction. Office times were measured using our patient ambulatory tracking system and by a research assistant outside the clinic room. To assess satisfaction we used items from the Consumer Assessment of Healthcare Providers and Systems survey (a federally developed standardized survey instrument) relevant to our study. Two weeks later, 51 (64%) patients were available for telephone followup and the same measures were completed. Mean time spent with the hand surgeon was 8 +/- A 5 minutes and mean in-office wait time to see the hand surgeon was 32 +/- A 18 minutes. A priori power analyses indicated that 77 patients would provide 80% power to detect an effect size f(2) = 0.18 for a regression with five predictors. This means that we would detect time spent with the physician as a significant factor if it accounted for 7% or more of the variability in satisfaction.
Time spent with the hand surgeon was not associated with patient satisfaction measured directly after the visit (r = -0.023; p = 0.84). Longer time waiting to see the physician correlated with decreased patient satisfaction (r = -0.30; p = 0.0057). The final multivariable model for increased satisfaction directly after the office visit included shorter waiting time (regression coefficient [beta] -0.0014; partial R-2 0.094; 95% confidence interval [CI], -0.0024 to -0.00042; p = 0.006) and being married/living with a partner (beta 0.057; partial R-2 0.11; 95% CI, 0.021-0.093; p = 0.002 [adjusted R-2 0.18; p < 0.001]). Similarly, multivariable analysis found higher patient satisfaction 2 weeks after the visit to be independently associated with shorter waiting time (beta -0.0037; partial R-2 0.10; 95% CI, -0.0070 to -0.00054; p = 0.023) and being married/living with a partner (beta 0.15; partial R-2 0.12; 95% CI, 0.033-0.26; p = 0.012 [adjusted R-2 0.16; p = 0.0052]).
Patient satisfaction among patients undergoing hand surgery may relate more to shorter time in the waiting room and to the quality more than the quantity of time spent with the patient.

AB Many patients having discretionary orthopaedic surgery take opioids daily, either with a prescription or illicitly, however little is known regarding the prevalence and effect of high-risk opioid use (eg, abuse, dependence) in the perioperative orthopaedic setting.
We sought (1) to determine the prevalence of opioid abuse and dependence in patients undergoing major elective orthopaedic surgery; (2) to characterize the relationship of opioid abuse and dependence with in-hospital postoperative mortality and adverse events, failure to rescue, prolonged length of stay, and nonroutine disposition; and (3) to identify factors associated with high-risk opioid use.
We used coding data collected in discharge records from the Nationwide Inpatient Sample (2002-2011). We analyzed changes with time in the prevalence of opioid abuse and dependence on admission. Finally, we used multivariate regression modeling to measure the association of opioid abuse and dependence with in-hospital postoperative mortality, morbidity, and resource utilization, and to identify factors associated with high-risk opioid use.
The prevalence of opioid abuse and dependence increased from 0.095% in 2002 to 0.24% in 2011, an increase of 152% (p < 0.001). Opioid abuse and dependence were associated with increased inpatient mortality (odds ratio [OR], 3.7; 95% CI, 2.7-5.1) and aggregate morbidity (OR, 2.3 l; 95% CI, 2.2-2.4), including induced mental disorder (OR, 5.9; 95% CI, 5.4-6.3), respiratory failure (OR, 3.1; 95% CI, 2.7-3.6), surgical site infection (OR, 2.5; 95% CI, 2.0-3.0), mechanical ventilation (OR, 2.3; 95% CI, 2.0-2.5), pneumonia (OR, 2.1; 95% CI, 1.8-2.3), myocardial infarction (OR, 1.9; 95% CI, 1.3-2.6), and postoperative ileus or other gastrointestinal events (OR, 1.4; 95% CI, 1.3-1.6) (p < 0.001 for all listed entities). Abuse and dependence also were associated with increased risk for prolonged hospital length of stay (OR, 2.5; 95% CI, 2.4-2.5), nonroutine discharge (OR, 2.2; 95% CI, 2.2-2.3), and failure to rescue (OR, 2.0; 95% CI, 1.4-2.8). High-risk opioid users were more likely to be younger, male, nonwhite, Medicaid-insured patients with mental health and substance use disorders, and to be undergoing spine surgery. Hospital-related characteristics included urban setting, geographic location in the Northeast or West, and serving as a teaching facility.
Opioid abuse and dependence are increasing rapidly among orthopaedic surgical inpatients and are associated with considerable postoperative morbidity and mortality and resource utilization. We recommend that orthopaedic surgeons screen patients carefully for opioid misuse preoperatively, help patients who are using opioids inappropriately to discontinue them before scheduling elective surgery, decline to perform elective surgery in patients who misuse opioids, and closely monitor patients who are habituated to opioids at the time they undergo surgery.

NEUROPLASTICITY
AB Aphasia therapy, while demonstrably successful, has been limited by its primary focus on language, with relatively less attention paid to nonlinguistic factors (cognitive, affective, praxic) that play a major role in recovery from aphasia. Neuroscientific studies of the past 15-20 years have opened a breach in the wall of traditional clinico-anatomical teachings on aphasia. It is not an exaggeration to talk of a paradigm shift. The term "neural multifunctionality" denotes a complex web of neural networks supporting both linguistic and nonlinguistic functions in constant and dynamic interaction, creating language as we know it and contributing to recovery from aphasia following brain damage. This paper reviews scientific underpinnings of neural multifunctionality and suggests ways in which this new approach to understanding the neural basis of language can lead to meaningful, practical steps for improvements in aphasia therapy.

AB Objective: Approximately 1 in 3 adults with diabetes have CKD. However, there are no recent national estimates of the association of CKD with medical care expenditures in individuals with diabetes. Our aim is to assess the association of CKD with total medical expenditures in US adults with diabetes using a national sample and novel cost estimation methodology.
Research design and methods: Data on 2,053 adults with diabetes in the 2011 Medical Expenditure Panel Survey (MEPS) was analyzed. Individuals with CKD were identified based on self-report. Adjusted mean health services expenditures per person in 2011 were estimated using a two-part model after adjusting for demographic and clinical covariates.
Results: Of the 2,053 individuals with diabetes, approximately 9.7% had self-reported CKD. Unadjusted mean expenditures for individuals with CKD were $ 20,726 relative to $ 9,689.49 for no CKD. Adjusted mean expenditures from the 2-part model for individuals with CKD were $ 8473 higher relative to individuals without CKD. Additional significant covariates were Hispanic/other race, uninsured, urban dwellers, CVD, stroke, high cholesterol, arthritis, and asthma. The estimated unadjusted total expenditures for individuals with CKD were estimated to be in excess of $ 43 billion in 2011.
Conclusions: We showed that CKD is a significant contributor to the financial burden among individuals with diabetes, and that minorities and the uninsured with CKD may experience barriers in access to care. Our study also provides a baseline national estimate of CKD cost in Diabetes by which future studies can be used for comparison. Published by Elsevier Ireland Ltd.

AB Sleep disruption is common in inflammatory bowel diseases (IBD). However, studies demonstrating a similar prevalence in irritable bowel syndrome suggest that nighttime disruption due to diarrhea and abdominal pain may be key drivers of poor sleep quality. Whether inflammation is associated with poor sleep independently has not been examined previously.
This single-center study included subjects with IBD recruited to an ongoing prospective registry who completed a questionnaire assessing sleep quality and mood. Inflammatory marker levels [C-reactive protein (CRP), erythrocyte sedimentation rate] and clinical disease activity including nighttime disruption on the day of enrollment were obtained from the medical record. Logistic regression models were used to identify predictors of sleep quality.
The study included 131 subjects (72 women) with a median age of IBD diagnosis of 25 years. Twenty-three subjects (19 %) had a high C-reactive protein level (a parts per thousand yen8 mg/dL). Poor sleep was more common in those with high CRP levels than with normal values (70 vs. 39 %, p = 0.009). This association remained significant on multivariate analysis [Odds ratio (OR) 4.12, 95 % confidence interval (CI) 1.38-12.29]. Adjusting for the presence of nighttime disruption did not significant alter this association (OR 3.16, 95 % CI 1.01-9.90). High CRP correlated with poor sleep even in patients not experiencing nocturnal symptoms (n = 101, OR 4.89, 95 % CI 1.24-19.36).
High CRP is associated with poor sleep quality in IBD independent of the presence of nighttime disruptions, suggesting that a relationship exists between circulating inflammatory markers and sleep.

AB Radiofrequency ablation of malignant biliary strictures has been offered for the last 3 years, but only limited data have been published.
To assess the safety, efficacy, and survival outcomes of patients receiving endoscopic radiofrequency ablation.
Between April 2010 and December 2013, 69 patients with unresectable neoplastic lesions and malignant biliary obstruction underwent 98 radiofrequency ablation sessions with stenting.
A total of 69 patients (22 male, aged 66.1 +/- A 13.3) were included in the registry. The etiology of malignant biliary stricture included unresectable cholangiocarcinoma (n = 45), pancreatic cancer (n = 19), gallbladder cancer (n = 2), gastric cancer (n = 1), and liver metastasis from colon cancer (n = 3). Seventy-eight percentage of patients had prior chemotherapy. All strictures were stented post-radiofrequency ablation with either plastic stents or metal stents. The mean stricture length treated was 14.3 mm. There was a statistically significant improvement in stricture diameter post-ablation (p < 0.0001). The likelihood of stricture improvement was significantly greater in pancreatic cancer-associated strictures [RR 1.8 (95 % 1.03-5.38)]. Seven patients (10 %) had adverse events, not linked directly to radiofrequency ablation. Median survival was 11.46 months (6.2-25 months).
Radiofrequency ablation is effective and safe in malignant biliary obstruction and seems to be associated with improved survival.

TI Reduced Albumin Dosing During Large-Volume Paracentesis Is Not

DE Paracentesis; Albumin; Cirrhosis; Renal disease
ID INDUCED CIRCULATORY DYSFUNCTION; CIRRHOSIS; PREVENTION; ASCITES;
MIDODRINE
AB LVP is used to manage diuretic-resistant ascites in cirrhotic patients. Albumin administration prevents complications including acute kidney injury and paracentesis-induced circulatory dysfunction, but the optimal dose is unclear.
We sought to assess adherence to guidelines enacted in July 2011 at our center for reducing the albumin dose administered at large-volume paracentesis (LVP) and evaluate the cost and rate of complications of LVPs before and after guideline enactment.
All LVPs performed on cirrhotic patients in our center's Department of Radiology between July 2009 and January 2014 were studied. Outcomes included adherence to guidelines, LVP complications, and administered albumin cost. Groups were compared using Student's t tests for continuous data and Chi-square or Fisher's exact tests for categorical data. A repeated measurements model accounted for patients with multiple LVPs.
Of the 935 LVPs, 288 occurred before guideline implementation (group 1) and 647 occurred after (group 2). The mean dose of albumin administered was 13.7 g/L of ascites removed in group 1 versus 10.3 g/L in group 2 (p < 0.0001). Of the group 2 LVPs, 235 (36.3 %) adhered to guidelines. There were no significant differences in LVP complications.
Guidelines were followed in one-third of LVPs. Despite this limited adherence, a reduction in albumin administration and associated cost savings was still observed. There was no increase in LVP-related complications after guideline implementation or in the adherent group, suggesting that albumin dose can be safely reduced. Future efforts should be directed at enhancing guideline adherence and potentially further reducing albumin dosing.

AB Background: Little is known about current societal attitudes toward women with significant mobility disability who are visibly pregnant.
Objective: To use qualitative descriptive analysis methods to examine perceptions of women with significant mobility disability about how strangers reacted to their visible pregnancies.
Methods: In late 2013, we conducted 2-h telephone interviews with 22 women with significant mobility difficulties who had delivered babies within the prior 10 years. The semi-structured, open-ended interview protocol addressed wide-ranging pregnancy-related topics, including statements from strangers. Most participants were recruited through social networks, coming from 17 states nationwide. We used NVivo to sort the texts for content analysis.
Results: The women's mean (standard deviation) age was 34.8 (5.3) years; most were white, well-educated, and higher income, although half had Medicaid during their pregnancies; and 18 used wheeled mobility aids. Eighteen women described memorable interactions with strangers relating to their pregnancies or newborn babies. Strangers' statements fell into six categories: (1) curious; (2) intrusively and persistently curious; (3) hostile, including concerns that taxpayers would end up supporting the mother and child; (4) questioning woman's competence as a potential parent; (5) oblivious, not recognizing visible pregnancy or motherhood; and (6) positive. Many women reported strangers asking how their pregnancy had happened. The women doubted that visibly pregnant women without disabilities evoke the same reactions from strangers.
Conclusions: Women with mobility disability who are visibly pregnant may perceive reactions from strangers that appear intrusive. Planning ahead for handling such encounters could reduce the stresses of these interactions. (C) 2015 Elsevier Inc. All rights reserved.

AB Introduction: Vemurafenib induces tumour regression in most patients with BRAF(V600E) - mutant melanoma; eventually, most experience progressive disease (PD). Long-term follow-up of patients with BRAF(V600E) melanoma treated in the phase 1 vemurafenib trial is reported.
Methods: Patients received vemurafenib 240-1120 mg (dose escalation cohort) or 960 mg (extension cohort) orally twice daily. Clinical response was evaluated every 8 weeks by Response Evaluation Criteria In Solid Tumors (RECIST). Patients with PD amenable to local therapy (surgery or radiotherapy) were allowed to continue vemurafenib after progression. Overall survival (OS) from time of treatment initiation and from PD was estimated. Sites of PD were recorded.
Results: Forty-eight patients (escalation cohort, n = 16; extension cohort, n = 32) received therapeutic doses of vemurafenib (>= 240 mg twice daily). Forty-four patients had PD by the time of this analysis and four remained progression free (follow-up time, 1.2-56.1 months). Median OS was 14 months (range, 1.2-56.1); 3- and 4-year melanoma-specific survival rate in the extension cohort was 26% and 19%, respectively. Median OS was 26.0 months (range, 7.7-56.1) among 20 patients who continued vemurafenib after local therapy. Median treatment duration beyond initial PD was 3.8 months (range, 1.1-26.6). In the extension cohort, six and five patients were alive after 3 and 4 years, respectively, on vemurafenib monotherapy.
Conclusions: Some patients with melanoma achieved long-term survival with vemurafenib monotherapy. Continuation of vemurafenib after PD might be beneficial in some patients because remaining disease might continue to respond to BRAF inhibition. (C) 2015 Elsevier Ltd. All rights reserved.

ID PRACTICE PARAMETER; SKIN BIOPSY; RECOMMENDATIONS
AB Background and purposeThe recently developed composite autonomic symptom score 31 (COMPASS-31) is a questionnaire that assess symptoms of dysautonomia. It was distilled from the well-established Autonomic Symptom Profile questionnaire. COMPASS-31 has not yet been externally validated. To do so, its psychometric properties and convergent validity in patients with and without objective diagnosis of small fiber polyneuropathy (SFPN) were assessed.
MethodsInternal validity and reliability of COMPASS-31 were assessed in participants with or without SFPN spanning the full range of severity of autonomic symptoms. Convergent validity was assessed by comparing results of the COMPASS-31 with the gold standard autonomic function testing that measures cardiovagal, adrenergic and sudomotor functions. Additionally, relationships between COMPASS-31 and the Short Form McGill Pain Questionnaire, Short Form Health Survey and 0-10 numeric pain scale were measured. COMPASS-31 and all other questionnaire results were compared between patients with or without evidence of SFPN, objectively confirmed by distal-leg PGP9.5-immunolabeled skin biopsy.
ResultsAmongst 66 participants (28 SFPN+, 38 SFPN-), COMPASS-31 total scores had excellent internal validity (Cronbach's =0.919), test-retest reliability (r(s)=0.886; P<0.001) and good convergent validity (r(s)=0.474; P<0.001). COMPASS-31 scores differed between subjects with or without SFPN (Z=-3.296, P<0.001) and demonstrated fair diagnostic accuracy. Area under the Receiver Operating Characteristic curve was 0.749 (P=0.01, 95% confidence interval 0.627-0.871).
ConclusionsCOMPASS-31 has good psychometric properties in the population of patients being evaluated for SFPN and thus it might be useful as an initial screening tool for the more expensive SFPN objective tests.

TI Patterns of Declining Use and the Adverse Effect of Primary Androgen
Deprivation on All-cause Mortality in Elderly Men with Prostate Cancer

AB Background: Primary androgen deprivation therapy (pADT) is commonly used to treat elderly men diagnosed with localized prostate cancer (CaP), despite the lack of evidence supporting its use.
Objective: To examine the effect of pADT on mortality and to assess contemporary trends of pADT use in elderly men with CaP.
Design, setting, and participants: Men older than 65 yr residing in Surveillance, Epidemiology, and End Results (SEER) registry areas diagnosed with localized or locally advanced CaP between 1992 and 2009 and not receiving definitive therapy.
Outcome measurements and statistical analysis: Propensity score (PS)-weighted Cox proportional hazards models were used to estimate the effect of pADT use on overall survival among patients receiving pADT. The interaction between comorbidity-adjusted life expectancy (LE) and pADT use was assessed within the Cox and PS-weighted models. Contemporary (2004-2009) trends for pADT use were analyzed by linear regression.
Results and limitations: The primary cohort included 46 376 men, of whom 17 873 received pADT (39%). Patients with >10 yr LE had lower pADT utilization rates than patients with short LE. Between 2004 and 2009, the use of pADT in men with localized CaP decreased by 14% (from 36% to 22%). Relative to observation, pADT was associated with a survival disadvantage, with a hazard ratio for all-cause mortality of 1.37 (95% confidence interval 1.20-1.56). Limitations included biases not accounted for by the PS-weighted model, changes in CaP staging over the study period, the absence of prostate-specific antigen (PSA) data prior to 2004, and the limits of retrospective analysis to demonstrate causality.
Conclusions: The use of pADT in elderly men with localized CaP has decreased over time. For men forgoing primary definitive therapy, the use of pADT is not associated with a survival benefit compared to observation, and denies men an opportunity for cure with definitive therapy. The deleterious effect of pADT is most pronounced in men with prolonged LE.
Patient summary: In this report, we assessed the effect of primary androgen deprivation (pADT) on prostate cancer mortality and determined current trends in the use of pADT. We showed that use of pADT in men aged >65 yr with localized prostate cancer has decreased over time. We also found that pADT is detrimental to men with localized prostate cancer, and particularly men with longer life expectancy. Therefore, we conclude that ADT should not be used as a primary treatment for men with prostate cancer that has not spread beyond the prostate. (C) 2014 European Association of Urology.

AB Background: Previous studies have reported on prognostic factors for castration-resistant prostate cancer (CRPC); however, most of these studies were conducted before docetaxel chemotherapy was approved for CRPC.
Objective: To evaluate the prognostic value of multiple parameters in men with bone metastases due to CRPC using a contemporary dataset.
Design, setting, and participants: The analysis included 1901 patients with metastatic CRPC enrolled in an international, multicenter, randomized, double-blind phase 3 trial conducted between May 2006 and October 2009.
Outcome measures and statistical analysis: We developed multivariate validated Cox proportional hazards models and nomograms to estimate 12-mo and 24-mo survival probabilities and median survival time.
Results and limitations: The median (95% confidence interval) overall survival was 20 (18, 21) mo. The final model included 12 of the 15 potential prognostic variables evaluated (concordance index 0.72). Seven bone-related variables were associated with longer survival in the final model: alkaline phosphatase <= 143 U/l (p < 0.0001); bone-specific alkaline phosphatase (BSAP) < 146 U/l (p < 0.0001); corrected urinary N-telopeptide (uNTx) <= 50 nmol/mmol (p = 0.0008); mild or no pain (Brief Pain Inventory-Short Form [BPI-SF] score <= 4) (p < 0.0001); no previous skeletal-related event (SRE; p = 0.0002); longer time from initial diagnosis to first bone metastasis (p < 0.0001); and longer time from first bone metastasis to randomization (p < 0.0001). Other significant predictors of improved survival included prostate-specific antigen (PSA) level < 10 ng/ml (p < 0.0001), hemoglobin >128 g/l (p < 0.0001), absence of visceral metastases (p < 0.0001), Eastern Co-operative Oncology Group (ECOG) score <= 1 (p = 0.017), and younger age (p = 0.008). Nomograms were generated based on the parameters included in the final validated models (with/without uNTx and BSAP). One limitation was that lactate dehydrogenase (LDH) levels, a known prognostic factor, were not available in this study.
Conclusions: Bone-related parameters are strong prognostic variables for overall survival in patients with bone metastases from CRPC.
Patient summary: Survival time is variable in patients with bone metastases from prostate cancer. We found that factors related to bone help to predict how long a patient will live. (C) 2014 European Association of Urology. Published by Elsevier B.V. All rights reserved.

AB Context: Partial nephrectomy (PN) is the current gold standard treatment for small localized renal tumors.; however, the impact of duration and type of intraoperative ischemia on renal function (RF) after PN is a subject of significant debate.
Objective: To review the current evidence on the relationship of intraoperative ischemia and RF after PN.
Evidence acquisition: A review of English-language publications on renal ischemia and RF after PN was performed from 2005 to 2014 using the Medline, Embase, and Web of Science databases. Ninety-one articles were selected with the consensus of all authors and analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.
Evidence synthesis: The vast majority of reviewed studies were retrospective, nonrandomized observations. Based on the current literature, RF recovery after PN is strongly associated with preoperative RF and the amount of healthy kidney parenchyma preserved. Warm ischemia time (WIT) is modifiable and prolonged warm ischemia is significantly associated with adverse postoperative RF. Available data suggest a benefit of keeping WIT <25 min, although the level of evidence to support this threshold is limited. Cold ischemia safely facilitates longer durations of ischemia. Surgical techniques that minimize or avoid global ischemia may be associated with improved RF outcomes.
Conclusions: Although RF recovery after PN is strongly associated with quality and quantity of preserved kidney, efforts should be made to limit prolonged WIT. Cold ischemia should be preferred when longer ischemia is expected, especially in presence of imperative indications for PN. Additional research with higher levels of evidence is needed to clarify the optimal use of renal ischemia during PN.
Patient summary: In this review of the literature, we looked at predictors of renal function after surgical resection of renal tumors. There is a strong association between the quality and quantity of renal tissue that is preserved after surgery and long-term renal function. The time of interruption of renal blood flow during surgery is an important, modifiable predictor of postoperative renal function. (C) 2015 European Association of Urology. Published by Elsevier B.V.

AB Urine protein loss in immune complex-mediated diseases such as lupus nephritis is associated with podocyte foot process effacement (podocytopathy) but is not always dependent on glomerular immune complex deposition. Several murine and human studies have associated lupus nephritis with inducible nitric oxide synthase (iNOS) expression in what appear to be podocytes. This study was conducted to determine mechanisms of immune-complex-independent and iNOS-dependent podocyte dysfunction. Conditionally immortalized podocytes were Cultured with lipopolysaccharide (LPS) and nitric oxide (NO), superoxide (SO), or peroxynitrite donors in the presence or absence of inhibitors of iNOS, reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase or monocyte chemotactic protein 1 (MCP-1), or with sepiapterin to increase coupling of iNOS homodimers. Podocyte NO, SO, and MCP-1 production and nitrotyrosine modifications were determined. The podocytopathy phenotype was determined by measuring cell Motility and membrane permeability to albumin. This study determined that NO produced by iNOS is sufficient and necessary to induce podocytopathy. NO probably induces this phenotype via hypoxia-inducible factor, its and cell division control protein 42 and Ras-related C3 botulinum toxin substrate 1 pathways. With LPS stimulation, neither SO nor peroxynitrite produced by uncoupled iNOS or NADPH oxidase nor MCP-1 was sufficient to induce the full phenotype. This study supports the notion that iNOS may induce autocrine podocyte dysfunction. Thus, targeting iNOS or the pathways of its induction may have therapeutic benefit. Published by Elsevier Inc.

AB There are more than 1 million primary hospitalizations for heart failure (HF) annually in the USA alone, and post-discharge outcomes remain persistently poor despite available therapies and quality improvement initiatives. Recent international randomized clinical trials in hospitalized HF have repeatedly failed to improve this post-discharge event rate. A potential reason for this persistent lack of clinical trial success that has not previously received significant attention relates to site selection and the generally low level of patient enrollment from the USA. Only similar to 5 % of US hospitals participate in clinical trials, and in four recent randomized trials of hospitalized HF, only one-third of patients were enrolled in North America. This poor participation among US centers has necessitated disproportionate enrollment from non-US sites. Regional variations in HF patient characteristics and clinical outcomes are well documented, and a lack of US patient representation in clinical trials limits the generalizability of results and presents obstacles for US regulatory agency approval. There are multiple impediments to successful US enrollment including a lack of incentive for investigators and institutions, the relative value unit-based compensation system, poor institutional framework for identification of appropriate patients, and increasing liability to conduct trials. In this manuscript, we specifically identify barriers to successful hospitalized HF clinical trial participation in the USA and suggest possible solutions.

AB With one possible exception, the last decade of clinical trials in hospitalized heart failure (HHF) patients has failed to demonstrate improvement in long-term clinical outcomes. This trend necessitates a need to evaluate optimal drug development strategies and standards of trial conduct. It has become increasingly important to recognize the heterogeneity among HHF patients and the differential characterization of novel drug candidates. Targeting these agents to specific subpopulations may afford optimal net response related to the particular mode of action of the drug. Analyses of previous trials demonstrate profound differences in the baseline characteristics of patients enrolled across global regions and participating sites. Such differences may influence risks for events and interpretation of results. Therefore, the actual execution of trials and the epidemiology of HHF populations at the investigative sites must be taken into consideration. Collaboration among participating sites including the provision of registry data tailored to the planned development program will optimize trial conduct. Observational data prior to study initiation may enable sites to feedback and engage in protocol development to allow for feasible and valid clinical trial conduct. This site-centered, epidemiology-based network environment may facilitate studies in specific patient populations and promote optimal data collection and clear interpretation of drug safety and efficacy. This review summarizes the roundtable discussion held by a multidisciplinary team of representatives from academia, National Institutes of Health, industry, regulatory agencies, payers, and contract and academic research organizations to answer the question: Who should be targeted for novel therapies in HHF?.

TI Alignment of systematic reviews published in the Cochrane Database of
Systematic Reviews and the Database of Abstracts and Reviews of
Effectiveness with global burden-of-disease data: a bibliographic
analysis
SO JOURNAL OF EPIDEMIOLOGY AND COMMUNITY HEALTH
LA English
DT Review
ID HEALTH-CARE; ASSOCIATION
AB Background Systematic reviews of high-quality evidence are used to inform policy and practice. To improve community health, the production of such reviews should align with burden of disease. This study aims to assess if the volume of research output from systematic reviews proportionally aligns with burden of disease assessed using percentages of mortality and disability-adjusted life years (DALYs).
Methods A cross-sectional audit of reviews published between January 2012 and August 2013 in the Cochrane Database of Systematic Reviews (CDSR) and Database of Abstracts of Reviews of Effects (DARE) was undertaken. Percentages of mortality and DALYs were obtained from the 2010 Global Burden of Disease study. Standardised residual differences (SRD) based on percentages of mortality and DALYs were calculated, where conditions with SRD of more than or less than three were considered overstudied or understudied, respectively.
Results 1029 reviews from CDSR and 1928 reviews from DARE were examined. There was a significant correlation between percentage DALYs and systematic reviews published in CDSR and DARE databases (CDSR: r=0.68, p=0.001; DARE: r=0.60, p<0.001). There was no significant correlation between percentage mortality and number of systematic reviews published in either database (CDSR: r=0.34, p=0.14; DARE: r=0.22, p=0.34). Relative to percentage of mortality, mental and behavioural disorders, musculoskeletal conditions and other non-communicable diseases were overstudied. Maternal disorders were overstudied relative to percentages of mortality and DALYs in CDSR.
Conclusions The focus of systematic reviews is moderately correlated with DALYs. A number of conditions may be overstudied relative to percentage of mortality particularly in the context of health and medical reviews.

AB The pathophysiology of acne vulgaris depends on active sebaceous glands, implying that selective destruction of sebaceous glands could be an effective treatment. We hypothesized that light-absorbing microparticles could be delivered into sebaceous glands, enabling local injury by optical pulses. A suspension of topically applied gold-coated silica microparticles exhibiting plasmon resonance with strong absorption at 800 nm was delivered into human pre-auricular and swine sebaceous glands in vivo, using mechanical vibration. After exposure to 1050 J cm(-2), 30 milliseconds, 800 nm diode laser pulses, microscopy revealed preferential thermal injury to sebaceous follicles and glands, consistent with predictions from a computational model. Inflammation was mild; gold particles were not retained in swine skin 1 month after treatment, and uptake in other organs was negligible. Two independent prospective randomized controlled clinical trials were performed for treatment of moderate-to-severe facial acne, using unblinded and blinded assessments of disease severity. Each trial showed clinically and statistically significant improvement of inflammatory acne following three treatments given 1-2 weeks apart. In Trial 2, inflammatory lesions were significantly reduced at 12 weeks (P = 0.015) and 16 weeks (P = 0.04) compared with sham treatments. Optical microparticles enable selective photothermolysis of sebaceous glands. This appears to be a well-tolerated, effective treatment for acne vulgaris.

AB The microphthalmia-associated transcription factor (MITF) is a key regulator of melanocyte development and a lineage-specific oncogene in melanoma; a highly lethal cancer known for its unpredictable clinical course. MITF is regulated by multiple intracellular signaling pathways, although the exact mechanisms that determine MITF expression and activity remain incompletely understood. In this study, we obtained genome-wide DNA methylation profiles from 50 stage IV melanomas, normal melanocytes, keratinocytes, and dermal fibroblasts and utilized The Cancer Genome Atlas data for experimental validation. By integrating DNA methylation and gene expression data, we found that hypermethylation of MITF and its co-regulated differentiation pathway genes corresponded to decreased gene expression levels. In cell lines with a hypermethylated MITF-pathway, overexpression of MITF did not alter the expression level or methylation status of the MITF pathway genes. In contrast, however, demethylation treatment of these cell lines induced MITF-pathway activity, confirming that gene regulation was controlled via methylation. The discovery that the activity of the master regulator of pigmentation, MITF, and its downstream targets may be regulated by hypermethylation has significant implications for understanding the development and evolvement of melanoma.

MELANOMA; REACTIVATION; MEK; VEMURAFENIB; SENSITIVITY; GROWTH; CANCER
AB Response to targeted therapies varies significantly despite shared oncogenic mutations. Nowhere is this more apparent than in BRAF (V600E)-mutated melanomas where initial drug response can be striking and yet relapse is commonplace. Resistance to BRAF inhibitors have been attributed to the activation of various receptor tyrosine kinases (RTKs), although the underlying mechanisms have been largely uncharacterized. Here, we found that EGFR-induced vemurafenib resistance is ligand dependent. We employed whole-genome expression analysis and discovered that vemurafenib resistance correlated with the loss of microphthalmia-associated transcription factor (MITF), along with its melanocyte lineage program, and with the activation of EGFR signaling. An inverse relationship between MITF, vemurafenib resistance, and EGFR was then observed in patient samples of recurrent melanoma and was conserved across melanoma cell lines and patients' tumor specimens. Functional studies revealed that MITF depletion activated EGFR signaling and consequently recapitulated the resistance phenotype. In contrast, forced expression of MITF in melanoma and colon cancer cells inhibited EGFR and conferred sensitivity to BRAF/MEK inhibitors. These findings indicate that an "autocrine drug resistance loop" is suppressed by melanocyte lineage signal(s), such as MITF. This resistance loop modulates drug response and could explain the unique sensitivity of melanomas to BRAF inhibition.

AB The choice of the motor donor nerve is a crucial point in free flap transfer algorithms. In the case of unilateral facial paralysis, the contralateral healthy facial nerve can provide coordinated smile animation and spontaneous emotional expression, but with unpredictable axonal ingrowth into the recipient muscle. Otherwise, the masseteric nerve ipsilateral to the paralysis can provide a powerful neural input, without a spontaneous trigger of the smile. Harvesting a bulky muscular free flap may enhance the quantity of contraction but esthetic results are unpleasant. Therefore, the logical solution for obtaining high amplitude of smiling combined with spontaneity of movement is to couple the neural input: the contralateral facial nerve plus the ipsilateral masseteric nerve.
Thirteen patients with unilateral dense facial paralysis underwent a one-stage facial reanimation with a gracilis flap powered by a double donor neural input, provided by both the ipsilateral masseteric nerve (coaptation by an end-to-end neurorrhaphy with the obturator nerve) and the contralateral facial nerve (coaptation through a cross-face nerve graft: end-to-end neurorrhaphy on the healthy side and end-to-side neurorrhaphy on the obturator nerve, distal to the masseteric/obturator neurorrhaphy). Their facial movements were evaluated with an optoelectronic motion analyzer.
Before surgery, on average, the paretic side exhibited a smaller total three-dimensional mobility than the healthy side, with a 52% activation ratio and >30% of asymmetry. After surgery, the differences significantly decreased (analysis of variance (ANOVA), p < 0.05), with an activation ratio between 75% (maximum smile) and 91% (maximum smile with teeth clenching), and <20% of asymmetry. Similar modifications were seen for the performance of spontaneous smiles.
The significant presurgical asymmetry of labial movements reduced after surgery. The use of a double donor neural input permitted both movements that were similar in force to that of the healthy side, and spontaneous movements elicited by emotional triggering.

AB Background: Given its nonspecific physical examination findings, accurately distinguishing cellulitis from a cellulitis mimicker (pseudocellulitis) is challenging.
Objective: We sought to investigate the national incidence of cellulitis misdiagnosis among inpatients.
Methods: We conducted a retrospective review of inpatient dermatology consultations at Massachusetts General Hospital, University of Alabama at Birmingham Medical Center, University of California Los Angeles Medical Center, and University of California San Francisco Medical Center in 2008. All consults requested for the evaluation of cellulitis were included. The primary outcomes were determining the incidence of cellulitis misdiagnosis, evaluating the prevalence of associated risk factors, and identifying common pseudocellulitides.
Results: Of the 1430 inpatient dermatology consultations conducted in 2008, 74 (5.17%) were requested for the evaluation of cellulitis. In all, 55 (74.32%) patients evaluated for cellulitis were given a diagnosis of pseudocellulitis. There was no statistically significant difference in the rate of misdiagnosis across institutions (P = .12). Patient demographics and associated risk factor prevalence did not statistically vary in patients given a diagnosis of cellulitis versus those with pseudocellulitis (P > .05).
Limitations: This study was unable to evaluate all patients admitted with cellulitis and was conducted at tertiary care centers, which may affect the generalizability of the results.
Conclusions: Cellulitis is commonly misdiagnosed in the inpatient setting. Involving dermatologists may improve diagnostic accuracy and decrease unnecessary antibiotic use.

AB Purpose: We examined differences in outcome in patients with biopsy Gleason score 8 vs 9-10 who received definitive local therapy.
Materials and Methods: Using an institutional database we identified a cohort of 847 patients with biopsy Gleason 8-10 disease who received definitive local therapy with radiation therapy or radical prostatectomy between January 2001 and December 2011. Multivariable Cox modeling was used to assess the association of Gleason score 8 vs 9-10 with time to biochemical recurrence, metastasis and overall survival, and evaluate treatment by Gleason score interaction. Median followup in the cohort was 5.3 years.
Results: Baseline patient characteristics were similar for biopsy Gleason 8 vs 9-10. Gleason 9-10 disease was associated with higher prostate specific antigen at diagnosis. As local treatment such patients were also more likely to have received radiation therapy (58% vs 46%, p = 0.001) and neoadjuvant/adjuvant androgen deprivation therapy (64% vs 49%, p < 0.001). Those with higher grade disease were at increased risk for metastasis (HR 1.41, 95% CI 1.11-1.79). There was a trend toward an increased risk of death in Gleason 9-10 vs 8 cases (HR 1.28, 95% CI 0.98-1.66). The increased risk of death for Gleason 9-10 was mainly observed in patients treated with radical prostatectomy with or without additional radiation therapy (HR 1.74, 95% CI 1.15-2.65).
Conclusions: Patients with localized biopsy Gleason 9-10 disease treated with definitive local therapy had worse outcomes than those diagnosed with biopsy Gleason 8 disease. Clinical trials are urgently needed that incorporate newer approaches to Gleason 9-10 cancer.

AB AimWomen with diabetes have a higher prevalence of chronic kidney disease (CKD) risk factors compared with men, but whether they are at higher risk for incident CKD remains uncertain.
MethodsThis was a prospective, observational cohort study of 1464 patients with diabetes and normal renal function, recruited from primary care clinics at a vertically integrated healthcare system in Seattle, WA, USA. The primary predictor was sex. Incident CKD was defined by an estimated glomerular filtration rate (eGFR)<60mL/min per 1.73m(2) by Chronic Kidney Disease-Epidemiology equations or sex-specific microalbuminuria (urine albumin/creatinine ratio 25mg/g for women or 17mg/g for men).
ResultsOf the 1464 patients (52.0% women), CKD incidence rates were 154.0 and 144.3 cases per 1000 patient-years for women and men, respectively. In the competing risks regression, women had an increased risk of incident CKD (sub-hazard ratio 1.37, 95% confidence interval (CI) 1.17, 1.60) compared with men after adjustment for demographics, baseline eGFR and duration of diabetes, which persisted after additional adjustment for CKD risk factors, depressive symptoms and diabetes self-care (sub-hazard ratio 1.35, 95% CI 1.15, 1.59). Sex differences in incident CKD were consistent across age groups and appeared to be driven by differences in the development of low eGFR rather than microalbuminuria.
ConclusionWomen with diabetes had a higher risk of incident CKD compared with men, which could not be entirely explained by differences in biologic CKD risk factors, depression or diabetes self-care. Additional work is needed determine if these sex differences contribute to worse outcomes in women with diabetes.
Summary at a Glance The authors have evaluated associations between sex and chronic kidney disease (CKD) incidence in a primary care population with diabetes using Chronic Kidney Disease-Epidemiology equations for estimating glomerular filtration rate (GFR) and sex-specific definitions of microalbuminuria. They found that women had an increased risk of incident CKD compared with men. They also found that this difference in incident CKD was primarily driven by differences in incident eGFR<60mL/min per 1.73m(2).

AB Objectives Nurses are at increased risk of occupational asthma, an observation that may be related to disinfectants exposure. Whether asthma history influences job type or job changes among nurses is unknown. We investigated this issue in a large cohort of nurses.
Methods The Nurses' Health Study II is a prospective study of US female nurses enrolled in 1989 (ages 2444 years). Job status and asthma were assessed in biennial (1989-2011) and asthma-specific questionnaires (1998, 2003). Associations between asthma history at baseline (diagnosis before 1989, n=5311) and job type at baseline were evaluated by multinomial logistic regression. The relations of asthma history and severity during follow-up to subsequent job changes were evaluated by Cox models.
Results The analytic cohort included 98 048 nurses. Compared with nurses in education/administration (likely low disinfectant exposure jobs), women with asthma history at baseline were less often employed in jobs with likely high disinfectant exposure, such as operating rooms (odds ratio 0.73 (95% CI 0.63 to 0.86)) and emergency room/inpatient units (0.89 (0.82 to 0.97)). During a 22-year follow-up, nurses with a baseline history of asthma were more likely to move to jobs with lower exposure to disinfectants (HR 1.13 (1.07 to 1.18)), especially among those with more severe asthma (HR for mild persistent: 1.13; moderate persistent 1.26; severe persistent: 1.50, compared with intermittent asthma, p trend: 0.004).
Conclusions Asthma history was associated with baseline job type and subsequent job changes among nurses. This may partly reflect avoidance of tasks involving disinfectant use, and may introduce bias in cross-sectional studies on disinfectant exposure and asthma in nurses.

AB From the earliest description of dysphagia relieved by dilatation with a whalebone in 1674 we have witnessed the evolution of esophageal function testing from the conventional manometry to the high-resolution manometry (HRM) and esophageal topography pressure plotting that have led to the revised Chicago classification for esophageal motility disorders in 2014. The goals of this paper are, therefore, (1) to highlight the historical milestones that have led to the diagnostic definition of achalasia, as we know it today; (2) to describe the evaluation process of patients with suspected achalasia; (3) to describe the diagnostic value of the HRM and the usefulness of the Chicago classification in predicting treatment outcomes. The value of Chicago classification is linked to the ability of the clinician to perform a thorough clinical evaluation to identify and correlate specific clinical phenotypes to specific manometric subtypes and predict treatment outcomes. Chicago classification, however, cannot predict which treatment, pneumatic dilatation, or Heller myotomy, should be selected for those with a specific subtype of achalasia.

FUNDOPLICATION; OUTCOMES; SURGERY
AB Epiphrenic diverticula are a rare disease almost always associated with an underlying motility disorder of the esophagus, such as achalasia. Treatment of any underlying motility disorder must be included in the management of epiphrenic diverticula to prevent postoperative complications and recurrences. Therefore, the goal of this paper is to describe the pathophysiology, clinical presentation, and proper methods of diagnosis and treatment of patients with epiphrenic diverticula. In addition, we aim to provide an overview of the surgical management and discuss the indications for surgery and choice of surgical approach. In general, surgical intervention is favored for symptomatic patients and the optimal surgical approach depends on the size and location of the diverticulum. Surgery is not without seemingly high rates of morbidity when a myotomy is not performed together with the diverticulectomy, even in those with normal manometry. The risk of carcinoma is exceedingly rare and it is usually discovered at later stages; therefore, no surveillance programs have been established in asymptomatic patients with unresected diverticula.

AB Subarachnoid hemorrhage (SAH) remains a condition with suboptimal functional outcomes, especially in the young population. Pharmacotherapy has an accepted role in several aspects of the disease and an emerging role in several others. No preventive pharmacologic interventions for SAH currently exist. Antiplatelet medications as well as anticoagulation have been used to prevent thromboembolic events after endovascular coiling. However, the main focus of pharmacologic treatment of SAH is the prevention of delayed cerebral ischemia (DCI). Currently the only evidence-based medical intervention is nimodipine. Other calcium channel blockers have been evaluated without convincing efficacy. Anti-inflammatory drugs such as statins have demonstrated early potential; however, they failed to provide significant evidence for the use in preventing DCI. Similar findings have been reported for magnesium, which showed potential in experimental studies and a phase 2 trial. Clazosentane, a potent endothelin receptor antagonist, did not translate to improve functional outcomes. Various other neuroprotective agents have been used to prevent DCI; however, the results have been, at best inconclusive. The prevention of DCI and improvement in functional outcome remain the goals of pharmacotherapy after the culprit lesion has been treated in aneurysmal SAH. Therefore, further research to elucidate the exact mechanisms by which DCI is propagated is clearly needed. In this article, we review the current pharmacologic approaches that have been evaluated in SAH and highlight the areas in which further research is needed.

AB We studied 1,292 Iraq and Afghanistan War veterans who participated in a clinical trial of expressive writing to estimate the prevalence of perceived reintegration difficulty and compare Veterans Affairs (VA) healthcare users to nonusers in terms of demographic and clinical characteristics. About half of participants perceived reintegration difficulty. VA users and nonusers differed in age and military background. Levels of mental and physical problems were higher in VA users. In multivariate analysis, military service variables and probable traumatic brain injury independently predicted VA use. Findings demonstrate the importance of research comparing VA users to nonusers to understand veteran healthcare needs.

AB Purpose Recurrence of endometriosis after conservative surgery has been observed in 40-50 % of patients within the first 5 years. A variety of regimens such as combined oral contraceptives, GnRH agonists, danazol, and progestins have been used postoperatively to reduce recurrence rates. Oral contraceptives (oCP) have been used either in a cyclic or in a continuous (no pill-free interval) fashion. The purpose of this article was to summarize the existing evidence on the efficacy and patient compliance for the use of oCP in a continuous versus cyclic fashion following conservative surgery for endometriosis.
Methods A systematic search of Medline identified four eligible studies. Studies were considered eligible, if they have evaluated oCP therapy, either in a cyclic or continuous regimen, after conservative surgery for endometriosis. Specifically, studies (1) reporting on women with endometriosis who were treated postoperatively with both continuous oCP and cyclic oCP, (2) written in English, (3) with minimum 6 months duration of medical treatment, and (4) with minimum 12 months duration of follow-up were considered eligible for our systematic review. Outcome measures of these eligible studies were tabulated and then analyzed cumulatively. A purely descriptive approach was adopted concerning all variables.
Results Postoperative use of continuous oCP was associated with a reduction in the recurrence rate of dysmenorrhea, delay in the presentation of dysmenorrhea, reduction in nonspecific pelvic pain, and reduction in the recurrence rate for endometrioma.
Conclusions Use of oCP in a continuous fashion following conservative surgery for endometriosis is more beneficial to cyclic use.

AB Behavioral disinhibition (BD) is a quantitative measure designed to capture the heritable variation encompassing risky and impulsive behaviors. As a result, BD represents an ideal target for discovering genetic loci that predispose individuals to a wide range of antisocial behaviors and substance misuse that together represent a large cost to society as a whole. Published genome-wide association studies (GWAS) have examined specific phenotypes that fall under the umbrella of BD (e.g. alcohol dependence, conduct disorder); however no GWAS has specifically examined the overall BD construct. We conducted a GWAS of BD using a sample of 1,901 adolescents over-selected for characteristics that define high BD, such as substance and antisocial behavior problems, finding no individual locus that surpassed genome-wide significance. Although no single SNP was significantly associated with BD, restricted maximum likelihood analysis estimated that 49.3 % of the variance in BD within the Caucasian sub-sample was accounted for by the genotyped SNPs (p = 0.06). Gene-based tests identified seven genes associated with BD (p a parts per thousand currency sign 2.0 x 10(-6)). Although the current study was unable to identify specific SNPs or pathways with replicable effects on BD, the substantial sample variance that could be explained by all genotyped SNPs suggests that larger studies could successfully identify common variants associated with BD.

AB Objective: To use cortical auditory evoked potentials (CAEPs) to understand neural encoding in background noise and the conditions under which noise enhances CAEP responses.
Methods: CAEPs from 16 normal-hearing listeners were recorded using the speech syllable/ba/presented in quiet and speech-shaped noise at signal-to-noise ratios of 10 and 30 dB. The syllable was presented binaurally and monaurally at two presentation rates.
Results: The amplitudes of N1 and N2 peaks were often significantly enhanced in the presence of low-level background noise relative to quiet conditions, while P1 and P2 amplitudes were consistently reduced in noise. P1 and P2 amplitudes were significantly larger during binaural compared to monaural presentations, while N1 and N2 peaks were similar between binaural and monaural conditions.
Conclusions: Methodological choices impact CAEP peaks in very different ways. Negative peaks can be enhanced by background noise in certain conditions, while positive peaks are generally enhanced by binaural presentations.
Significance: Methodological choices significantly impact CAEPs acquired in quiet and in noise. If CAEPs are to be used as a tool to explore signal encoding in noise, scientists must be cognizant of how differences in acquisition and processing protocols selectively shape CAEP responses.

AB This paper evaluates a prototype flat-panel volume CT (fpVCT) for dynamic in vivo imaging in a variety of neurovascular and lower limb applications.
Dynamic CTA was performed on 12 patients (neuro = 8, lower limb = 4) using an fpVCT with 120 kVp, 50 mA, rotation time varying from 8 to 19 s, and field of view of 25 x 25 x 18 cm(3). Four-dimensional data sets (i.e. 3D images over time) were reconstructed and reviewed.
Dynamic CTA demonstrated sufficient spatio-temporal resolution to elucidate first-pass and recirculation dynamics of contrast bolus through neurovasclaur pathologies and phasic blood flow though lower-limb vasculature and grafts. The high spatial resolution of fpVCT resulted in reduced partial volume and metal beam-hardening artefacts. This facilitated assessment of vascular lumen in the presence of calcified plaque and evaluation of fractures, especially in the presence of fixation hardware. Evaluation of arteriovenous malformation using dynamic fpVCT angiography was of limited utility.
Dynamic CTA using fpVCT can visualize time-varying phenomena in neuro and lower limb vascular applications and has suffcient diagnostic imaging quality to evaluate a number of pathologies affecting these regions.
aEuro cent CTA using fpVCT has sufficient spatial and temporal resolution to study phasic blood flow.
aEuro cent CTA using fpVCT reveals recurrence of aneurysms even after clipping/coiling.
aEuro cent fpVCT has reduced partial volume and metal beam-hardening artefacts.
aEuro cent fpVCT can show vessel lumen in the presence of calcified plaque.
aEuro cent CTA using fpVCT can demonstrate vascular supply to transplanted grafts.

AB Objective: This randomized controlled trial examined the effectiveness of a nurse assisted online cognitive-behavioral self-management intervention forwar-related posttraumatic stress disorder (PTSD), compared to optimized usual primary care PTSD Treatment (OUC) to reduce PTSD symptoms.
Method: Participants were 80 veterans of recent military conflicts with PTSD as assessed by the PTSD Checklist (PCL) seeking primary care treatment at one of three Veterans Affairs (VA) and four Army clinics. DESTRESS-PC consisted of logins to a secure website three times per week for 6 weeks with monitoring by a study nurse. All participants received nurse care management in the form of phone check-ins every two weeks and feedback to their primary care providers. Blinded raters assessed outcomes 6, 12, and 18 weeks post-randomization.
Results: DESTRESS-PC was associated with a significantly greater decrease in PTSD symptoms compared to OUC (F(3, 186)=3.72, p=.012). The effect was largest at the 12-week assessment (Delta PCL=12.6 +/- 16.6 versus 5.7 +/- 12.5, p<0.05) with the treatment effect disappearing by the 18-week follow-up. Notably, there was a dose effect; number of logins correlated significantly with PTSD outcomes, with more logins associated with greater PTSD symptom improvement. None of the secondary outcomes (depression, anxiety, somatic symptoms, and functional status) showed statistically significant improvement; however, the treatment effect on depression approached significance (F(3, 186)=2.17, p=.093).
Conclusions: DESTRESS-PC shows promise as a means of delivering effective, early PTSD treatment in primary care. Larger trials are needed. (C) 2015 Elsevier Inc. All rights reserved.

TI Treatment Guidelines for Preoperative Radiation Therapy for

AB Purpose: Evidence for external beam radiation therapy (RT) as part of treatment for retroperitoneal sarcoma (RPS) is limited. Preoperative RT is the subject of a current randomized trial, but the results will not be available for many years. In the meantime, many practitioners use preoperative RT for RPS, and although this approach is used in practice, there are no radiation treatment guidelines. An international expert panel was convened to develop consensus treatment guidelines for preoperative RT for RPS.
Methods and Materials: An expert panel of 15 academic radiation oncologists who specialize in the treatment of sarcoma was assembled. A systematic review of reports related to RT for RPS, RT for extremity sarcoma, and RT-related toxicities for organs at risk was performed. Due to the paucity of high-quality published data on the subject of RT for RPS, consensus recommendations were based largely on expert opinion derived from clinical experience and extrapolation of relevant published reports. It is intended that these clinical practice guidelines be updated as pertinent data become available.
Results: Treatment guidelines for preoperative RT for RPS are presented.
Conclusions: An international panel of radiation oncologists who specialize in sarcoma reached consensus guidelines for preoperative RT for RPS. Many of the recommendations are based on expert opinion because of the absence of higher level evidence and, thus, are best regarded as preliminary. We emphasize that the role of preoperative RT for RPS has not been proven, and we await data from the European Organization for Research and Treatment of Cancer (EORTC) study of preoperative radiotherapy plus surgery versus surgery alone for patients with RPS. Further data are also anticipated pertaining to normal tissue dose constraints, particularly for bowel tolerance. Nonetheless, as we await these data, the guidelines herein can be used to establish treatment uniformity to aid future assessments of efficacy and toxicity. (C) 2015 Elsevier Inc.

AB Background: Previous studies of surgeon behavior report that surgeons rarely meet basic standards of informed consent, raising concerns that current practice requires urgent remediation. We wondered if the Veterans Affairs Healthcare System's recent implementation of standardized, procedure-specific consent forms might produce a better practice of informed consent than has been reported previously. Our goal was to determine how the discussions shared between surgeons and patients correspond to the VA's standardized consent forms.
Methods: We enrolled a prospective cohort of patients presenting for possible cholecystectomy or inguinal herniorrhaphy and the surgical providers for those patients. Audio recordings captured the clinical encounter(s) culminating in a decision to have surgery. Each patient's informed consent was documented using a standardized, computer-generated form. We abstracted and compared the information documented with the information discussed.
Results: Of 75 consecutively enrolled patients, 37 eventually decided to have surgery and signed the standardized consent form. Patients and providers discussed 37% (95% confidence interval, 0.07-0.67) and 33% (95% confidence interval, 0.21-0.43) of the information found on the cholecystectomy and herniorrhaphy consent forms, respectively. However, the patienteprovider discussions frequently included relevant details nowhere documented on the standardized forms, culminating in discussions that included a median 27.5 information items for cholecystectomy and 20 items for herniorrhaphy. Fully, 80% of cholecystectomy discussions and 76% of herniorrhaphy discussions mentioned at least one risk, benefit or alternative, indication for, and description of the procedure.
Conclusions: The patients and providers observed here collaborated in a detailed process of informed consent that challenges the initial reports suggesting the need to remediate surgeon's practice of informed consent. However, because the discrepancy between the information documented and discussed exposes legal and ethical liability, there is an opportunity to improve the iMed system so that it better reflects what surgeons discuss and more frequently includes all the information patients need.

AB The elongation factor Tu GTP binding domain-containing protein 2 (EFTUD2) was identified as an anti-hepatitis C virus (HCV) host factor in our recent genome-wide small interfering RNA (siRNA) screen. In this study, we sought to further determine EFTUD2's role in HCV infection and investigate the interaction between EFTUD2 and other regulators involved in HCV innate immune (RIG-I, MDA5, TBK1, and IRF3) and JAK-STAT1 pathways. We found that HCV infection decreased the expression of EFTUD2 and the viral RNA sensors RIG-I and MDA5 in HCV-infected Huh7 and Huh7.5.1 cells and in liver tissue from in HCV-infected patients, suggesting that HCV infection downregulated EFTUD2 expression to circumvent the innate immune response. EFTUD2 inhibited HCV infection by inducing expression of the interferon (IFN)-stimulated genes (ISGs) in Huh7 cells. However, its impact on HCV infection was absent in both RIG-I knockdown Huh7 cells and RIG-I-defective Huh7.5.1 cells, indicating that the antiviral effect of EFTUD2 is dependent on RIG-I. Furthermore, EFTUD2 upregulated the expression of the RIG-I-like receptors (RLRs) RIG-I and MDA5 to enhance the innate immune response by gene splicing. Functional experiments revealed that EFTUD2-induced expression of ISGs was mediated through interaction of the EFTUD2 downstream regulators RIG-I, MDA5, TBK1, and IRF3. Interestingly, the EFTUD2-induced antiviral effect was independent of the classical IFN-induced JAK-STAT pathway. Our data demonstrate that EFTUD2 restricts HCV infection mainly through an RIG-I/MDA5-mediated, JAK-STAT-independent pathway, thereby revealing the participation of EFTUD2 as a novel innate immune regulator and suggesting a potentially targetable antiviral pathway.
IMPORTANCE
Innate immunity is the first line defense against HCV and determines the outcome of HCV infection. Based on a recent highthroughput whole-genome siRNA library screen revealing a network of host factors mediating antiviral effects against HCV, we identified EFTUD2 as a novel innate immune regulator against HCV in the infectious HCV cell culture model and confirmed that its expression in HCV-infected liver tissue is inversely related to HCV infection. Furthermore, we determined that EFTUD2 exerts its antiviral activity mainly through governing its downstream regulators RIG-I and MDA5 by gene splicing to activate IRF3 and induce classical ISG expression independent of the JAT-STAT signaling pathway. This study broadens our understanding of the HCV innate immune response and provides a possible new antiviral strategy targeting this novel regulator of the innate response.

AB Objective: The purpose was to examine recent advances in measuring value concordance and to highlight best practices.
Methods: The paper updates a prior systematic review. A systematic review of the literature from 2008 to 2012 identified articles that reported a relationship between patients' preferences concerning health outcomes and/or medical treatments, and treatment (intended or actual). Relevant articles were independently abstracted by two reviewers.
Results: The search identified 3635 unique citations, the full text of 187 articles was examined, and 63 articles covering 61 studies were included, nearly a third more articles than identified in the original review. There were 72 different value concordance calculations, the majority of which were clearly reported with significance. More studies assessed knowledge, reported on the association between value concordance and knowledge, and included a decision aid compared to those in the original review.
Conclusion: There is increased reporting of value concordance in the literature. However, large differences exist in the way that the measure is defined and calculated. The variability makes it difficult to draw conclusions about the quality of care across studies.
Practice implications: Value concordance is a critical component of patient-centered care, and further attention is needed to establish standards for measurement and reporting. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

TI Measuring Psychosocial Environments Using Individual Responses: an
Application of Multilevel Factor Analysis to Examining Students in
Schools
SO PREVENTION SCIENCE
LA English

variable; Ecological

AB Interest in understanding how psychosocial environments shape youth outcomes has grown considerably. School environments are of particular interest to prevention scientists as many prevention interventions are school-based. Therefore, effective conceptualization and operationalization of the school environment is critical. This paper presents an illustration of an emerging analytic method called multilevel factor analysis (MLFA) that provides an alternative strategy to conceptualize, measure, and model environments. MLFA decomposes the total sample variance-covariance matrix for variables measured at the individual level into within-cluster (e.g., student level) and between-cluster (e.g., school level) matrices and simultaneously models potentially distinct latent factor structures at each level. Using data from 79,362 students from 126 schools in the National Longitudinal Study of Adolescent to Adult Health (formerly known as the National Longitudinal Study of Adolescent Health), we use MLFA to show how 20 items capturing student self-reported behaviors and emotions provide information about both students (within level) and their school environment (between level). We identified four latent factors at the within level: (1) school adjustment, (2) externalizing problems, (3) internalizing problems, and (4) self-esteem. Three factors were identified at the between level: (1) collective school adjustment, (2) psychosocial environment, and (3) collective self-esteem. The finding of different and substantively distinct latent factor structures at each level emphasizes the need for prevention theory and practice to separately consider and measure constructs at each level of analysis. The MLFA method can be applied to other nested relationships, such as youth in neighborhoods, and extended to a multilevel structural equation model to better understand associations between environments and individual outcomes and therefore how to best implement preventive interventions.

AB Background. Numerous studies have reported links between theory of mind (ToM) deficits, neurocognition and negative symptoms with functional outcome in chronic schizophrenia patients. Although the ToM deficit has been observed in first-episode patients, fewer studies have addressed ToM as a possible trait marker, neurocognitive and symptom correlations longitudinally, and associations with later functioning.
Method. Recent-onset schizophrenia patients (n = 77) were assessed at baseline after reaching medication stabilization, and again at 6 months (n = 48). Healthy controls (n = 21) were screened, and demographically comparable with the patients. ToM was assessed with a Social Animations Task (SAT), in which the participants' descriptions of scenes depicting abstract visual stimuli 'interacting' in three conditions (ToM, goal directed and random) were rated for degree of intentionality attributed to the figures and for appropriateness. Neurocognition, symptoms and role functioning were also assessed.
Results. On the SAT, patients had lower scores than controls for both intentionality (p < 0.01) and appropriateness (p < 0.01) during the ToM condition, at baseline and 6 months. The ToM deficit was stable and present even in remitted patients. Analyses at baseline and 6 months indicated that for patients, ToM intentionality and appropriateness were significantly correlated with neurocognition, negative symptoms and role functioning. The relationship between ToM and role functioning was mediated by negative symptoms.
Conclusions. The ToM deficit was found in recent-onset schizophrenia patients and appears to be moderately trait-like. ToM is also moderately correlated with neurocognition, negative and positive symptoms, and role functioning. ToM appears to influence negative symptoms which in turn makes an impact on role functioning.

AB We examined the association between posttraumatic stress disorder (PTSD) and gene expression using whole blood samples from a cohort of trauma-exposed white non-Hispanic male veterans (115 cases and 28 controls). 10,264 probes of genes and gene transcripts were analyzed. We found 41 that were differentially expressed in PTSD cases versus controls (multiple-testing corrected p <0.05). The most significant was DSCAM, a neurological gene expressed widely in the developing brain and in the annygdala and hippocampus of the adult brain. We then examined the 41 differentially expressed genes in a meta-analysis using two replication cohorts and found significant associations with PTSD for 7 of the 41 (p <0.05), one of which (ATP6AP1L) survived multiple-testing correction. There was also broad evidence of overlap across the discovery and replication samples for the entire set of genes implicated in the discovery data based on the direction of effect and an enrichment of p <0.05 significant probes beyond what would be expected under the null. Finally, we found that the set of differentially expressed genes from the discovery sample was enriched for genes responsive to glucocorticoid signaling with most showing reduced expression in PTSD cases compared to controls.

AB OBJECTIVE To document the lived experiences of people with both poor mental health and suboptimal adherence to antiretroviral therapy in high HIV prevalence settings.
METHODS In-depth qualitative interviews were conducted with 47 (female = 31) HIV-positive adults who scored above the cut-point on a locally validated scale for common mental disorders (CMDs). Purposive sampling was used to recruit participants with evidence of poor adherence. Six additional key informant interviews (female = 6) were conducted with healthcare workers. Data were collected and analysed inductively by an interdisciplinary coding team.
RESULTS The major challenges faced by participants were stressors (poverty, stigma, marital problems) and symptoms of CMDs ('thinking too much', changes to appetite and sleep, 'burdened heart' and low energy levels). Thinking too much, which appears closely related to rumination, was the symptom with the greatest negative impact on adherence to antiretroviral therapy among HIV-positive adults with CMDs. In turn, thinking too much was commonly triggered by the stressors faced by people living with HIV/AIDS, especially poverty. Finally, participants desired private counselling, access to income-generating activities and family engagement in mental health care.
CONCLUSIONS Better understanding of the local expression of mental disorders and of underlying stressors can inform the development of culturally sensitive interventions to reduce CMDs and poor adherence to antiretroviral therapy.

AB Background-The performance of the Japan-chronic total occlusion (J-CTO) score in predicting success and efficiency of CTO percutaneous coronary intervention has received limited study.
Methods and Results-We examined the records of 650 consecutive patients who underwent CTO percutaneous coronary intervention between 2011 and 2014 at 6 experienced centers in the United States. Six hundred and fifty-seven lesions were classified as easy (J-CTO= 0), intermediate (J-CTO= 1), difficult (J-CTO= 2), and very difficult (J-CTO= 3). The impact of the J-CTO score on technical success and procedure time was evaluated with univariable logistic and linear regression, respectively. The performance of the logistic regression model was assessed with the Hosmer-Lemeshow statistic and receiver operator characteristic curves. Antegrade wiring techniques were used more frequently in easy lesions (97%) than very difficult lesions (58%), whereas the retrograde approach became more frequent with increased lesion difficulty (41% for very difficult lesions versus 13% for easy lesions). The logistic regression model for technical success demonstrated satisfactory calibration and discrimination (P for Hosmer-Lemeshow = 0.743 and area under curve = 0.705). The J-CTO score was associated with a 2-fold increase in the odds of technical failure (odds ratio 2.04, 95% confidence interval 1.52-2.80, P< 0.001). Procedure time increased by approximate to 20 minutes for every 1-point increase of the J-CTO score (regression coefficient 22.33, 95% confidence interval 17.45-27.22, P< 0.001).
Conclusions-J-CTO score was strongly associated with final success and efficiency in this study, supporting its expanded use in CTO interventions.

AB Objective: Traumatic brain injury (TBI) is now recognized as a major public health concern in the United States and is associated with substantial morbidity and mortality in both children and adults. Several lines of evidence indicate that TBI-induced hypopituitarism is not infrequent in TBI survivors and may contribute to the burden of illness in this population. The goal of this article is to review the published data and propose an approach for the neuroendocrine evaluation and management of these patients.
Methods: To identify pertinent articles, electronic literature searches were conducted using the following keywords: "traumatic brain injury," "pituitary," "hypopituitarism," "growth hormone deficiency," "hypogonadism," "hypoadrenalism," and "hypothyroidism." Relevant articles were identified and considered for inclusion in the present article.
Results: TBI-induced hypopituitarism appears to be more common in patients with severe TBI. However, patients with mild TBI or those with repeated, sports-, or blast-related TBI are also at risk for hypopituitarism. Deficiencies of growth hormone and gonadotropins appear to be most common and have been associated with increased morbidity in this population. A systematic approach is advised in order to establish the presence of pituitary hormone deficiencies and implement appropriate replacement therapies.
Conclusion: The presence of traumatic hypopituitarism should be considered during the acute phase as well as during the rehabilitation phase of patients with TBI. All patients with moderate to severe TBI require evaluation of pituitary function. In addition, symptomatic patients with mild TBI and impaired quality of life are at risk for hypopituitarism and should be offered neuroendocrine testing.

TI A Clinical Prediction Model to Assess Risk for Chemotherapy-Related
Hospitalization in Patients Initiating Palliative Chemotherapy
SO JAMA ONCOLOGY
LA English
DT Article
ID OLDER-ADULTS; CANCER; TOXICITY; CARE; COST; CRITERIA
AB IMPORTANCE Chemotherapy-related hospitalizations in patients with advanced cancer are common, distressing, and costly. Methods to identify patients at high risk of chemotherapy toxic effects will permit development of targeted strategies to prevent chemotherapy-related hospitalizations.
OBJECTIVE To demonstrate the feasibility of using readily available clinical data to assess patient-specific risk of chemotherapy-related hospitalization.
DESIGN, SETTING, AND PARTICIPANTS Nested case-control study conducted from January 2003 through December 2011 at the Mass General/North Shore Cancer Center, a community-based cancer center in northeastern Massachusetts. The parent cohort included 1579 consecutive patients with advanced solid-tumor cancer receiving palliative-intent chemotherapy. Case patients (n = 146) included all patients from the parent cohort who experienced a chemotherapy-related hospitalization. Controls (n = 292) were randomly selected from 1433 patients who did not experience a chemotherapy-related hospitalization.
EXPOSURES Putative risk factors for chemotherapy-related hospitalization-including patient characteristics, treatment characteristics, and pretreatment laboratory values-were abstracted from medical records. Multivariable logistic regression was used to model the patient-specific risk of chemotherapy-related hospitalization.
MAIN OUTCOMES AND MEASURES Chemotherapy-related hospitalization, as adjudicated by the oncology clinical care team within a systematic quality-assessment program.
RESULTS A total of 146 (9.2%) of 1579 patients from the parent cohort experienced a chemotherapy-related hospitalization. In multivariate regression, 7 variables were significantly associated with chemotherapy-related hospitalization: age, Charlson comorbidity score, creatinine clearance, calcium level, below-normal white blood cell and/or platelet count, polychemotherapy (vs monotherapy), and receipt of camptothecin chemotherapy. The median predicted risk of chemotherapy-related hospitalization was 6.0% (interquartile range [IQR], 3.6%-11.4%) in control patients and 14.7%(IQR, 6.8%-22.5%) in case patients. The bootstrap-adjusted C statistic was 0.71 (95% CI, 0.66-0.75). At a risk threshold of 15%, the model exhibited a sensitivity of 49% (95% CI, 41%-57%) and a specificity of 85%(95% CI, 81%-89%) for predicting chemotherapy-related hospitalization.
CONCLUSIONS AND RELEVANCE In patients initiating palliative chemotherapy for cancer, readily available clinical data were associated with the patient-specific risk of chemotherapy-related hospitalization. External validation and evaluation in the context of a clinical decision support tool are warranted.

TI Statin Use at the Time of Initiation of Androgen Deprivation Therapy and
Time to Progression in Patients With Hormone-Sensitive Prostate Cancer

AB IMPORTANCE Statin use has been associated with improved prostate cancer outcomes. Dehydroepiandrosterone sulfate (DHEAS) is a precursor of testosterone and a substrate for SLCO2B1, an organic anionic transporter. We previously demonstrated that genetic variants of SLCO2B1 correlated with time to progression (TTP) during receipt of androgen deprivation therapy (ADT). Statins also use SLCO2B1 to enter cells, and thus we hypothesized that they may compete with DHEAS uptake by the tumor cells. OBJECTIVE To evaluate whether statin use prolongs TTP during ADT for hormone-sensitive prostate cancer.
DESIGN, SETTING, AND PARTICIPANTS In vitro studieswere performed using prostate cancer cell lines at an academic, comprehensive cancer center. Statin use was retrospectively analyzed in 926 patients who had received ADT for biochemical or metastatic recurrence or de novo metastatic prostate cancer between January 1996 and November 2013.
MAIN OUTCOMES AND MEASURES To determine whether statins interfere with DHEAS uptake, we performed in vitro studies using prostate cancer cell lines. Next, we queried our institutional clinical database to assess for an association between statin use and TTP during ADT using multivariable Cox regression analysis and adjusted for known prognostic factors.
RESULTS In vitro, we demonstrated that statins block DHEAS uptake by competitively binding to SLCO2B1. In our ADT cohort of 926 patients, 283 (31%) were taking a statin at ADT initiation. After a median follow-up of 5.8 years, 644 patients (70%) had experienced disease progression while receiving ADT. Median TTP during ADT was 20.3 months (95% CI, 18-24 months). Men taking statins had a longer median TTP during ADT compared with nonusers (27.5 [95% CI, 21.1-37.7] vs 17.4 [95% CI, 14.9-21.1] months; P < .001). The association remained statistically significant after adjusting for predefined prognostic factors (adjusted hazard ratio, 0.83 [95% CI, 0.69-0.99]; P = .04). The positive statin effect was observed for both patients with and without metastases (adjusted hazard ratio, 0.79 [95% CI, 0.58-1.07] forM0 disease and 0.84 [95% CI, 0.67-1.06] forM1 disease; P for interaction = .72).
CONCLUSIONS AND RELEVANCE Statin use at the time of ADT initiation was associated with a significantly longer TTP during ADT even after adjustment for known prognostic factors. Our in vitro finding that statins competitively reduce DHEAS uptake, thus effectively decreasing the available intratumoral androgen pool, affords a plausible mechanism to support the clinical observation of prolonged TTP in statin users.

ID COMPLICATION; MALFORMATION
AB Retinal venous occlusive events are a rare complication of arteriovenous malformations of the retina found in Wyburn-Mason syndrome. The authors present a case of a 28-year-old man diagnosed with Wyburn-Mason syndrome and cutaneous reactive angiomatosis, a reactive angioproliferative disorder induced by vascular occlusion. He developed a central retinal vein occlusion complicated by macular edema and received treatment with intravitreal bevacizumab, which led to resolution of the edema. To the best of the authors' knowledge, this is the first report of an antivascular endothelial growth factor agent employed as an effective treatment for macular edema in the setting of Wyburn-Mason syndrome. The association between Wyburn-Mason syndrome and cutaneous reactive angiomatosis is also a novel finding.

ID CHRONIC MYELOGENOUS LEUKEMIA
AB The authors report a new clinical manifestation of chronic myeloid leukemia. A 41-year-old man presented with significant visual loss, leading to a diagnosis of chronic myeloid leukemia. His white blood count exceeded that of any previously reported case of the disease with documented retinal findings (562,000/mm(3)), and clinical evaluation revealed the blockage of temporal retinal vessels by white blood cells. Hematologic findings resolved within 1 month of chemotherapy with dasatinib, and further treatment with intravitreal anti-VEGF agents resulted in the complete resolution of fundus findings. The authors propose that leukostasis retinopathy be recognized as a clinical manifestation of this life-threatening disease.

AB Variability in fear conditionability is common, and clarity regarding the neural regions responsible for individual differences in fear conditionability could uncover brain-based biomarkers of resilience or vulnerability to trauma-based psychopathologies (e.g., post-traumatic stress disorder). In recent years, neuroimaging work has yielded a detailed understanding of the neural mechanisms underlying fear conditioning common across participants, however only a minority of studies have investigated the brain basis of inter-individual variation in fear learning. Moreover, the majority of these studies have employed small sample sizes (mean n=17; range n=5-27) and all have failed to meet the minimum recommended sample size for functional magnetic resonance imaging (fMRI) studies of individual differences. Here, using fMRI, we analyzed blood-oxygenation level dependent (BOLD) response recorded simultaneously with skin conductance response (SCR) and ratings of unconditioned stimulus (US) expectancy in 49 participants undergoing Pavlovian fear conditioning. On average, participants became conditioned to the conditioned stimulus (CS+; higher US expectancy ratings and SCR for the CS+ compared to the unpaired conditioned stimulus, CS-); the CS+ also robustly increased activation in the bilateral insula. Amygdala activation was revealed from a regression analysis that incorporated individual differences in fear conditionability (i.e., a between-subjects regressor of mean CS+ > CS- SCR). By replicating results observed using much smaller sample sizes, the results confirm that variation in amygdala reactivity covaries with individual differences in fear conditionability. The link between behavior (SCR) and brain (amygdala reactivity) may be a putative endophenotype for the acquisition of fear memories. (C) 2015 Elsevier B.V. All rights reserved.

AB With the recent publication of multiple trials demonstrating the superiority of the endovascular treatment of patients presenting with stroke from large vessel occlusion (LVO) over medical management, the emergent care of these patients is entering a new era. This realization justifies an aggressive treatment approach with these stroke patients, given the poor natural history of the disease. In general, treatment should occur as quickly as is reasonably possible. Patients with NIHSS >8 should be considered, and if <6 h from onset imaging selection achieved with CT and CTA. Those with ASPECTS 95, LVO and intermediate or good collaterals should be treated emergently. For patients with clinical deficits presenting in later timeframes MRI should be used to define core infarct size and therefore treatment eligibility. MRI might also be considered for the workup of stroke patients in centers that can offer it rapidly. Recanalization should be attempted with a stentriever or using a direct aspiration technique, with the patient under conscious sedation rather than general anesthesia, if that is a safe option. Angiographically, the goal is reperfusion of mTICI 2b/3. Post-procedure, the patient should be admitted to an intensive care setting and assessed for inpatient rehabilitation placement as soon as stable. Continuous institutional process improvement ensures that optimization of treatment times and logistics is an ongoing endeavor. Finally, patient outcomes should be assessed at three months, most commonly using the modified Rankin score.

AB Purpose: To evaluate whether trabectedin as first-line chemotherapy for advanced/metastatic soft tissue sarcoma prolongs progression-free survival (PFS), compared to doxorubicin and, in the phase IIb part here, to select the most appropriate trabectedin treatment schedule (3-hour or 24-hour infusion) in terms of safety, convenience and efficacy.
Patients and methods: In this randomised multicentre prospective dose-selection phase IIb superiority trial, 133 patients were randomised between doxorubicin (n = 43), trabectedin (3-hour infusion, T3h) (n = 47) and trabectedin (24-hour infusion, T24h) (n = 43). PFS was defined as time from random assignment until objective progression by response evaluation criteria in solid tumours (RECIST 1.1), a global deterioration of the health status requiring discontinuation of the treatment, or death from any cause.
Results: The study was terminated due to lack of superiority in both trabectedin treatment arms as compared to the doxorubicin control arm. Median PFS was 2.8 months in the T3h arm, 3.1 months in the T24h arm and 5.5 months in the doxorubicin arm. No significant improvements in PFS were observed in the trabectedin arms as compared to the doxorubicin arm (T24h versus doxorubicin: hazard ratio (HR) 1.13, 95% confidence interval (CI) 0.67-1.90, P = .675; T3h versus doxorubicin: HR 1.50, 95% CI 0.91-2.48, P = .944). Only one toxic death occurred in the T3h arm, but treatment had to be stopped due to toxicity in 7 (15.2%) (T3h), 8 (19.5%) (T24h) and 1 (2.5%) doxorubicin patients.
Conclusion: Doxorubicin continues to be the standard treatment in eligible patients with advanced/metastatic soft-tissue sarcoma (STS). Trabectedin 1.5 mg/m(2)/24-hour infusion is the overall proven approach to delivering this agent in the second-line setting for patients with advanced or metastatic STS. (C) 2015 Elsevier Ltd.

AB Assessment of a pediatric breast lesion always starts with clinical evaluation. When imaging of a pediatric breast is indicated, ultrasound is the mainstay. The vast majority of pediatric breast complaints are of benign etiology, therefore the diagnostic/management approach emphasizes "first do no harm". Correlation with age and clinical history helps to direct diagnosis. It is essential to be familiar with the imaging appearance of the normal developing breast at various Tanner stages, in order to diagnose physiologic breast findings and to minimize unnecessary biopsies in young breasts vulnerable to injury. Normal anatomic structures, developmental conditions, benign neoplastic and non-neoplastic lesions are common causes of breast complaints in children. Uncommon benign masses and rarely, secondary more than primary malignancies may present in a pediatric breast. Chest wall masses such as Ewing's sarcoma or rhabdomyosarcoma occur in children and may involve the breast via contiguous growth or locoregional metastasis. In addition, special attention should be given to any breast lesion in a child with risk factors predisposing to breast cancer, such as known extramammary malignancy, genetic mutations, prior mantle irradiation, or strong family history of breast cancer, which usually requires biopsy to exclude the possibility of malignancy.
Conclusion: The developing breast is vulnerable to injury, and because breast malignancy is uncommon in children, diagnostic and management approach emphasizes "first do no harm". Understanding normal breast development and the spectrum of common and uncommon pediatric breast lesions are key to the correct diagnosis. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB The objective of this study was to develop a predictive model for cell seeding depth in electrospun scaffold as a function of fiber stiffness. Electrospun scaffolds (micron and submicron) and 3T3 fibroblasts are used as scaffold-cell systems under vacuum seeding conditions. Atomic force microscopy is used to determine the Young's modulus (E) as a function of fiber diameter. A higher E value led to a lower depth of cell seeding (closer to the surface) indicating that nanofibrous scaffolds offer higher resistance to cell movement compared to microfibrous scaffold. An energy balance model was developed to predict cell seeding depth as a function of E for various vacuum pressures. Experimental data was used in the model to extract unknown parameters to predict cell seeding depth as a function of vacuum pressure for different stiffness scaffolds.

AB Applications for fracture-adapted screw positioning offered by variable angle locking screws are increasing. The locking strength of the variable angle locking mechanism at different insertion angles was compared to conventional fixed angle locking screws. Stainless steel (S) and titanium (Ti) variable and fixed angle 2.4mm locking screws, inserted at different inclinations (0 degrees-15 degrees), and locked at 0.8Nm were subjected to a load-to-failure test. Ultimate failure moment at the screw-head interface and failure mode of the screws were determined. Significant differences were detected by one-way ANOVA (p<0.05). Stainless steel and titanium variable angle locking screws inserted at 2 degrees-10 degrees inclination exhibited a failure moment comparable to the 0 degrees position (S 1.67 +/- 0.04Nm; Ti 1.67 +/- 0.14Nm) and failed predominantly at the screw neck, with the head remaining fixed to the plate. Inserted at 15 degrees inclination, screws revealed a lower failure moment (S 1.33 +/- 0.06Nm, Ti 1.58 +/- 0.05Nm), and failed predominantly by breakout of the head thread. Fixed angle locking screws inserted at an inclination >2 degrees did not lock properly in the plate hole, providing insufficient locking strength. Variable angle locking screws offer a stable head-locking mechanism at different inclinations, comparable to the locking strength of orthogonal inserted fixed angle locking screws. Marginal inclinations >15 degrees should be used with care. (c) 2015 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 33:988-992, 2015.

AB Rotator cuff tears (RCTs) are among the most common musculoskeletal injuries seen by orthopaedic surgeons. Clinically, massive cuff tears lead to unique pathophysiological changes in rotator cuff muscle, including atrophy, and massive fatty infiltration, which are rarely seen in other skeletal muscles. Studies in a rodent model for RCT have demonstrated that these histologic findings are accompanied by activation of the Akt/mammalian target of rapamycin (mTOR) and transforming growth factor- (TGF-) pathways following combined tendon-nerve injury. The purpose of this study was to compare the histologic and molecular features of rotator cuff muscle and gastrocnemius musclea major hindlimb muscle, following combined tendon-nerve injury. Six weeks after injury, the rat gastrocnemius did not exhibit notable fatty infiltration compared to the rotator cuff. Likewise, the adipogenic markers SREBP-1 and PPAR as well as the TGF- canonical pathway were upregulated in the rotator cuff, but not the gastrocnemius. Our study suggests that the rat rotator cuff and hindlimb muscles differ significantly in their response to a combined tendon-nerve injury. Clinically, these findings highlight the unique response of the rotator cuff to injury, and may begin to explain the poor outcomes of massive RCTs compared to other muscle-tendon injuries.

AB Stair climbing is a physically demanding task and a painful limitation for patients suffering from severe hip osteoarthritis. Although total hip arthroplasty (THA) is the definitive treatment for end-stage osteoarthritis, it is not well understood whether THA restores hip kinematics during strenuous activities. The purpose of this study was to compare the 3D kinematics of THA and native hip during physically demanding tasks and correlate potential differences with THA components orientations/positions in patients with unilateral THA. In vivo hip kinematics were determined during step-up and leg stance activities using a validated combination of 3D CT-based computer modeling and dual fluoroscopic imaging system (DFIS). The THA side demonstrated an average 3.4 degrees (+/- 6.5 degrees, range: -5.9 degrees to 15.2 degrees) greater internal rotation than the contralateral native hip, during the step-up activity but not during leg stance. The difference in internal rotation was highly correlated to the difference in femoral anteversion and anterior translation of hip joint center between implanted and native hip (R-2=0.71, p<0.01). The results suggest the importance of accurate THA component placement in restoring normal hip kinematics during functional activities. (c) 2015 Orthopaedic Research Society.

AB Naturalistic stimuli such as movies are increasingly used to engage cognitive and emotional processes during fMRI of brain hemodynamic activity. However, movies have been little utilized during magnetoencephalography (MEG) and EEG that directly measure population-level neuronal activity at a millisecond resolution. Here, subjects watched a 17-min segment from the movie Crash (Lionsgate Films, 2004) twice during simultaneous MEG/EEG recordings. Physiological noise components, including ocular and cardiac artifacts, were removed using the DRIFTER algorithm. Dynamic estimates of cortical activity were calculated using MRI-informed minimum-norm estimation. To improve the signal-to-noise ratio (SNR), principal component analyses (PCA) were employed to extract the prevailing temporal characteristics within each anatomical parcel of the Freesurfer Desikan-Killiany cortical atlas. A variety of alternative inter-subject correlation (ISC) approaches were then utilized to investigate the reliability of inter-subject synchronization during natural viewing. In the first analysis, the ISCs of the time series of each anatomical region over the full time period across all subject pairs were calculated and averaged. In the second analysis, dynamic ISC (dISC) analysis, the correlation was calculated over a sliding window of 200 ms with 3.3 ms steps. Finally, in a between-run ISC analysis, the between-run correlation was calculated over the dynamic ISCs of the two different runs after the Fisher z-transformation. Overall, the most reliable activations occurred in occipital/inferior temporal visual and superior temporal auditory cortices as well as in the posterior cingulate, precuneus, pre- and post-central gyri, and right inferior and middle frontal gyri. Significant between-run ISCs were observed in superior temporal auditory cortices and inferior temporal visual cortices. Taken together, our results show that movies can be utilized as naturalistic stimuli in MEG/EEG similarly as in fMRI studies. (C) 2015 Elsevier Inc. All rights reserved.

AB Reach and grasp kinematics are known to be encoded in the spiking activity of neuronal ensembles and in local field potentials (LFPs) recorded from primate motor cortex during movement planning and execution. However, little is known, especially in LFPs, about the encoding of kinetic parameters, such as forces exerted on the object during the same actions. We implanted two monkeys with microelectrode arrays in the motor cortical areas MI and PMd to investigate encoding of grasp-related parameters in motor cortical LFPs during planning and execution of reach-and-grasp movements. We identified three components of the LFP that modulated during grasps corresponding to low (0.3-7 Hz), intermediate(similar to 10-similar to 40 Hz) and high (similar to 80-250 Hz) frequency bands. We show that all three components can be used to classify not only grip types but also object loads during planning and execution of a grasping movement. In addition, we demonstrate that all three components recorded during planning or execution can be used to continuously decode finger pressure forces and hand position related to the grasping movement. Low and high frequency components provide similar classification and decoding accuracies, which were substantially higher than those obtained from the intermediate frequency component. Our results demonstrate that intended reach and grasp kinetic parameters are encoded in multiple LFP bands during both movement planning and execution. These findings also suggest that the LFP is a reliable signal for the control of parameters related to object load and applied pressure forces in brain-machine interfaces. (C) 2015 Elsevier Inc.

AB Despite the stated goals of the transplant community and the majority of organ allocation systems, persistent racial disparities in pediatric kidney transplantation exist throughout the world. These disparities are evident in both living and deceased donor kidney transplantation and are independent of any clinical differences between racial groups. The reasons for these persistent disparities are multifactorial, reflecting both patient and provider barriers to care. In this review, we examine the most current findings regarding disparities in pediatric kidney transplantation and consider interventions which may help reduce those disparities.

AB Major depression is the largest single healthcare burden with treatments of slow onset and often limited efficacy. Ketamine, a NMDA antagonist used extensively as a pediatric and veterinary anesthetic, has recently been shown to be a rapid acting antidepressant, making it a potential lifesaver for suicidal patients. Side effects and risk of abuse limit the chronic use of ketamine. More complete understanding of the neurobiochemical mechanisms of ketamine should lead to safer alternatives. Some of the physiological and pharmacological actions of ketamine are consistent with increased synthesis and release of TRH (pGlu-His-Pro-NH2), and TRH-like peptides (pGlu-X-Pro-NH2) where "X" can be any amino acid residue. Moreover, TRH-like peptides are themselves potential therapeutic agents for the treatment of major depression, anxiety, bipolar disorder, epilepsy, Alzheimer's and Parkinson's diseases. For these reasons, male Sprague-Dawley rats were anesthetized with 162 mg/kg ip ketamine and then infused intranasally with 20 mu l of sterile saline containing either 0 or 5 mg/ml Glu-TRH. One, 2 or 4 h later, the brain levels of TRH and TRH-like peptides were measured in various brain regions and peripheral tissues. At 1 h in brain following ketamine only, the levels of TRH and TRH-like peptides were significantly increased in 52 instances (due to increased biosynthesis and/or decreased release) or decreased in five instances. These changes, listed by brain region in order of decreasing number of significant increases (up arrow) and/or decreases (down arrow), were: hypothalamus (9 up arrow); piriform cortex (8 up arrow); entorhinal cortex (7 up arrow); nucleus accumbens (7 up arrow); posterior cingulate (5 up arrow); striatum (4 up arrow); frontal cortex (2 up arrow,3 down arrow); amygdala (3 up arrow); medulla oblongata (1 up arrow,2 down arrow); cerebellum (2 up arrow); hippocampus (2 up arrow); anterior cingulate (2 up arrow). The corresponding changes in peripheral tissues were: adrenals (8 up arrow); epididymis (4 up arrow); testis (1 up arrow,3 down arrow); pancreas (1 up arrow); prostate (1 up arrow). We conclude that TRH and TRH-like peptides may be downstream mediators of the rapid antidepressant actions of ketamine. Published by Elsevier Inc.

AB Background: Community pharmacists play a vital part in reconciling medications for patients transitioning from hospital to community care, yet their roles have not been fully examined in the extant literature.
Objectives: The objectives of this study were to: 1) examine the barriers and facilitators community pharmacists face when reconciling medications for recently discharged patients; and 2) identify pharmacists' preferred content and modes of information transfer regarding updated medication information for recently discharged patients.
Methods: Community pharmacists were purposively and conveniently sampled from the Wisconsin (U.S. state) pharmacist-based research network, Pharmacy Practice Enhancement and Action Research Link (PEARL Rx). Community pharmacists were interviewed face-to-face, and transcriptions from audio recordings were analyzed using directed content analysis. The Theory of Planned Behavior (TPB) guided the development of questions for the semi-structured interviews.
Results: Interviewed community pharmacists (N = 10) described the medication reconciliation process to be difficult and time-consuming for recently discharged patients. In the context of the TPB, more barriers than facilitators of reconciling medications were revealed. Themes were categorized as organizational and individual-level themes. Major organizational-level factors affecting the medication reconciliation process included: pharmacy resources, discharge communication, and hospital resources. Major individual-level factors affecting the medication reconciliation process included: pharmacists' perceived responsibility, relationships, patient perception of pharmacist, and patient characteristics. Interviewed pharmacists consistently responded that several pieces of information items would be helpful when reconciling medications for recently discharged patients, including the hospital medication discharge list and stop-orders for discontinued medications.
Conclusions: The TPB was useful for identifying barriers and facilitators of medication reconciliation for recently discharged patients from community pharmacists' perspectives. The elucidation of these specific facilitators and barriers suggest promising avenues for future research interventions to improve exchange of medication information between the community pharmacy, hospitals, and patients.

AB To identify factors associated with parent activation in parents of children undergoing pediatric hematopoietic stem cell transplant (HSCT) in the 6 months following HSCT, and to address if their association with parent activation changes over time.
Measures for this analysis, including the Parent-Patient Activation Measure (Parent-PAM), were completed by parents (N = 198) prior to their child's HSCT preparative regimen and again at 6 months post-HSCT. Clinical data were also collected. A repeated measures model was built to estimate the association between clinical and demographic factors and parent well-being on Parent-PAM scores. Interactions with time were considered to test for changing effects over time.
Throughout the HSCT course, older parent age was associated with lower Parent-PAM scores (beta = -0.29, p = 0.02) and never being married was associated with higher scores (versus married, beta = 12.27, p = 0.03). While higher parent emotional functioning scores were not associated with activation at baseline, they were important at 6 months (baseline, beta = -0.002, p = 0.96; interaction, beta = 0.14, p = 0.03). At baseline, longer duration of illness was associated with increased activation, but this effect diminished with time (baseline, beta = 3.29, p = 0.0002; interaction, beta = -2.40, p = 0.02). Activation levels dropped for parents of children who went from private to public insurance (baseline, beta = 2.95, p = 0.53; interaction, beta = -13.82, p = 0.004). Clinical events did not affect Parent-PAM scores.
Our findings reveal important changes in the factors associated with parent activation in the first 6 months after pediatric HSCT. These findings may reflect the emotional and financial toll of pediatric HSCT on parent activation.

AB PDZD8 can bind the capsid proteins of different retroviruses, and transient knockdown of PDZD8 results in a decrease in the efficiency of an early, post-entry event in the retrovirus life cycle. Here we used the CRISPR-CAS9 system to create cell lines in which PDZD8 expression is stably eliminated. The PDZD8-knockout cell lines were infected by human immunodeficiency virus (HIV-1) and murine leukemia virus as efficiently as the parental PDZD8-expressing cells. These results indicate that PDZD8 is not absolutely necessary for HIV-1 infection and diminishes its attractiveness as a potential target for intervention. (C) 2015 Elsevier Inc. All rights reserved.

AB Macrophages express low levels of the CD4 receptor compared to T-cells. Macrophage-tropic HIV strains replicating in brain of untreated patients with HIV-associated dementia (HAD) express Envs that are adapted to overcome this restriction through mechanisms that are poorly understood. Here, bioinformatic analysis of env sequence datasets together with functional studies identified polymorphisms in the beta 3 strand of the HIV gp120 bridging sheet that increase M-tropism. D197, which results in loss of an N-glycan located near the HIV Env trimer apex, was detected in brain in some HAD patients, while position 200 was estimated to be under positive selection. D197 and T/V200 increased fusion and infection of cells expressing low CD4 by enhancing gp120 binding to CCR5. These results identify polymorphisms in the HIV gp120 bridging sheet that overcome the restriction to macrophage infection imposed by low CD4 through enhanced gp120-CCR5 interactions, thereby promoting infection of brain and other macrophage-rich tissues.

AB In the present study, we evaluated the Milwaukee Inventory for Subtypes of Trichotillomania-Adult Version (MIST-A) in a replication sample of clinically characterized hair pullers using exploratory factor analysis (EFA; N = 193). EFA eigenvalues and visual inspection of our scree plot revealed a two-factor solution. Factor structure coefficients and internal consistencies suggested a 13-item scale with an 8-item Intention scale and a 5-item Emotion scale. Both scales displayed good construct and discriminant validity. These findings indicate the need for a revised scale that provides a more refined assessment of pulling phenomenology that can facilitate future treatment advances.

AB Somatic mutations in exon 2 of MED12 have been described in benign and malignant smooth muscle cell tumors suggesting a functional role in these neoplasms. Recently fibroadenomas of the breast were also reported to harbor MED12 mutations. Hence, we explored MED12 mutations in fibroepithelial tumors of the breast, histological subtypes of fibroadenomas and phyllodes tumors, to validate and extend previous efforts. Using conventional Sanger sequencing, we profiled 39 cases of fibroepithelial breast tumors comprising classic histological subtypes of fibroadenomas as well as benign and malignant phyllodes tumors for mutations in exon 2 of MED12. MED12 mutations were detected in 60% of all tumor samples with the majority being missense mutations affecting codon 44. Additionally, we report novel in-frame deletions that have not been described previously. Sixty-two percent of the fibroadenomas harbored mutated MED12 with intracanalicular fibroadenomas being the most frequently mutated histological subtype (82%). Of note, 8/11 of benign phyllodes tumors had MED12 mutations while only 1/5 of malignant phyllodes tumors showed mutations in exon 2 of MED12. In conclusion, we confirm the frequent occurrence of MED12 mutations in fibroadenomas, provide evidence that most intracanalicular fibroadenomas closely resembling benign phyllodes as well as benign phyllodes tumors harbor MED12 mutations, and conclude that MED12 mutations in malignant phyllodes tumors appear to be relatively rare.

AB High-voltage-activated calcium channels are hetero-oligomeric protein complexes that mediate multiple cellular processes, including the influx of extracellular Ca2+, neurotransmitter release, gene transcription, and synaptic plasticity. These channels consist of a primary (1) pore-forming subunit, which is associated with an extracellular (2) subunit and an intracellular auxiliary subunit, which alter the gating properties and trafficking of the calcium channel. The cellular localization of the (23) subunit in the mouse and rat retina is unknown. In this study using RT-PCR, a single band at approximate to 305 bp corresponding to the predicted size of the (23) subunit fragment was found in mouse and rat retina and brain homogenates. Western blotting of rodent retina and brain homogenates showed a single 123-kDa band. Immunohistochemistry with an affinity-purified antibody to the (23) subunit revealed immunoreactive cell bodies in the ganglion cell layer and inner nuclear layer and immunoreactive processes in the inner plexiform layer and the outer plexiform layer. (23) immunoreactivity was localized to multiple cell types, including ganglion, amacrine, and bipolar cells and photoreceptors, but not horizontal cells. The expression of the (23) calcium channel subunit to multiple cell types suggests that this subunit participates widely in Ca-channel-mediated signaling in the retina. J. Comp.

AB Phonotactic frequency effects play a crucial role in a number of debates over language processing and representation. It is unclear however, whether these effects reflect prelexical sensitivity to phonotactic frequency, or lexical "gang effects" in speech perception. In this paper, we use Granger causality analysis of MR-constrained MEG/EEG data to understand how phonotactic frequency influences neural processing dynamics during auditory lexical decision. Effective connectivity analysis showed weaker feedforward influence from brain regions involved in acoustic-phonetic processing (superior temporal gyrus) to lexical areas (supramarginal gyrus) for high phonotactic frequency words, but stronger top-down lexical influence for the same items. Low entropy nonwords (nonwords judged to closely resemble real words) showed a similar pattern of interactions between brain regions involved in lexical and acoustic-phonetic processing. These results contradict the predictions of a feedforward model of phonotactic frequency facilitation, but support the predictions of a lexically mediated account. (C) 2015 Elsevier Inc.

AB Septic arthritis is an important concern for rheumatologists in the evaluation of joint disease. Very few studies have addressed the microbiologic epidemiology and outcomes of septic arthritis in the USA since the year 2000. We performed a retrospective study of septic arthritis in a tertiary hospital in West Texas from the year 2000 to 2013. We recorded data on patient demographics, microbiologic etiology, treatment patterns, and outcomes. The most common causative organisms were Staphylococcus aureus and Streptococcus spp. Methicillin-resistant Staphylococcus aureus (MRSA) caused septic arthritis in 22.6 % of the cases. MRSA septic arthritis was associated with low rates of adequate empiric antimicrobial therapy. The mortality due to sepsis in our study was 5.5 %. Patients with septic arthritis had a mean length of stay of 13.5 +/- A 12.1 days and required 2.1 +/- A 1.4 joint operations. Many patients (29.2 %) had readmissions due to complications, and these patients had high rates of home health utilization and transfers to other facilities post hospital discharge. In our logistic regression analysis model, factors associated with poor outcomes in septic arthritis were MRSA, older age, and prosthetic joint infection. Septic arthritis is associated with significant mortality, morbidity, and health care costs, and more studies are needed to improve outcomes, especially considering the increasing rates of MRSA as the pathogen.

AB Diffusion-weighted imaging (DWI) provides essential information regarding tumor composition, such as cellularity and/or perfusion. DWI is helpful in distinguishing between malignant and benign lesions. Malignant intramuscular/soft tissue lesions consist of a wide spectrum of tumors that have different cell counts and matrix. It is presumed that these different tumors have different DWI findings and have different apparent diffusion coefficient (ADC) values. The aim of this study was to analyze DWI findings of different intramuscular malignancies in a multicentric study by using a standardized DWI protocol, and to compare the ADC values acquired.
The data banks of four radiology departments were screened retrospectively for malignant intramuscular tumors. Only lesions that were investigated by MRI (with a 1.5-T scanner) using DWI (multishot EPI sequence with b values of 0 and 1,000 s/mm(2)) were included in the study. Overall, 51 patients (28 women, 23 men; mean age 58.8 +/- 16.1 years) with 57 different malignant intramuscular lesions were collected. In every case apparent diffusion constant (ADC) maps were calculated. In 14 patients muscle lymphoma, 11 patients intramuscular metastases from different primary tumors, and in 26 cases several muscle sarcomas were identified.
The mean ADC value of the estimated lesions was 1.24 +/- 0.53 x 10(-3) mm(2)s(-1), median value, 1.11 x 10(-3) mm(2)s(-1), range, 0.54-2.9 x 10(-3) mm(2)s(-1). The mean ADC value in muscle metastases was 1.28 +/- 0.24 x 10(-3) mm(2)s(-1), in muscle lymphoma 0.76 +/- 0.14 x 10(-3) mm(2)s(-1), and in muscle sarcomas 1.82 +/- 0.63 x 10(-3) mm(2)s(-1). Muscle lymphoma showed statistically significant lower ADC values in comparison to muscle metastases (p = 0.01) and muscle sarcoma (p = 0.001). There was no significant differences between ADC values in muscle metastases and sarcomas (p = 0.48). ADC values in muscle lymphoma were homogeneous with less inter-patient variability and were within a relatively close range. Muscle sarcomas had a broad range of ADC values.
Intramuscular malignant lesions had different ADC values on DWI. 22.8 % of the tumors analyzed had low ADC values, 26.3 % moderate, and 50.9 % high ADC values. Muscle lymphoma had statistically significantly lower ADC values in comparison to muscle metastases and sarcomas. Muscle sarcomas presented with a broad range of ADC values.

AB The inhibition of the 90-kDa heat shock protein (HSP90) leads to upregulation of the 70-kDa-inducible HSP70. HSP70 has been previously shown to be neuroprotective and anti-inflammatory. Geldanamycin (GA) and other HSP90 inhibitors have emerged as promising therapeutic agents in cancer, presumably owing to their ability to upregulate HSP70. However, the effects of HSP90 inhibition in brain inflammation are still unclear. We investigate the effect of a panel of HSP90 inhibitors on endotoxin-activated microglia and eventual protection from brain-derived endothelial cells. Prior studies have shown that GA protects brain cells from oxidative stress. We show here that when astrocytes or microglial BV2 cells were pretreated with GA or other HSP90 inhibitors, endotoxin-induced cell death was reduced in cocultures of BV2 microglia and brain-derived endothelial cells (bEND.3). Endotoxin-stimulated BV2 cells led to increased nitric oxide (NO) and inducible nitric oxide synthase which was prevented by treatment with all HSP90 inhibitors. HSP90 inhibitors also prevented lipopolysaccharide (LPS)-induced BV2 cell death. We also found that HSP90 inhibition blocked nuclear translocation of nuclear factor kappa B and attenuated IB degradation, and inhibited LPS-activated JAK-STAT phosphorylation. We show that pharmacologic inhibition of HSP90 with subsequent HSP70 induction protects cells that comprise the cerebral vasculature against cell death owing to proinflammatory stimuli. This approach may have therapeutic potential in neurological conditions with an inflammatory component.

AB Circulating adiponectin has been associated with lower risk of colorectal cancer (CRC). Genome-wide association studies have identified several single-nucleotide polymorphisms (SNPs) associated with adiponectin levels. However, it is unclear whether these SNPs are associated with CRC risk. In addition, previous data on SNPs in the adiponectin pathway and their associations with CRC are inconsistent. Therefore, we examined 19 SNPs in genes related to adiponectin or its receptors and their associations with CRC using logistic regression among 7,020 cases and 7,631 controls drawn from ten studies included in the Genetics and Epidemiology of Colorectal Cancer Consortium. Using data from a subset of two large cohort studies, we also assessed the contribution of individual SNPs and an adiponectin genetic score to plasma adiponectin after accounting for lifestyle factors among 2,217 women and 619 men. We did not find any statistically significant association between the 19 adiponectin-associated SNPs and CRC risk (multivariable-adjusted odds ratios ranged from 0.89 to 1.05, all p>0.05). Each SNP explained less than 2.50% of the variance of plasma adiponectin, and the genetic score collectively accounted for 2.95 and 1.42% of the variability of adiponectin in women and men, respectively, after adjustment for age, body mass index, physical activity, smoking, alcohol consumption, regular use of aspirin or nonsteroidal anti-inflammatory drug and postmenopausal hormone use. In conclusion, our findings do not support an association between known adiponectin-related common SNPs and CRC incidence. However, known common SNPs account for only a limited proportion of the interindividual variance in circulating adiponectin. Further work is warranted to investigate the relationship between adiponectin and CRC while accounting for other components in the pathway.
What's new? Obesity is a well-established risk factor for colorectal cancer, and mounting evidence suggests that the adipocyte-derived hormone adiponectin is behind that link. In the present investigation, common genetic variants in the adiponectin (ADIPOQ) gene were analyzed for potential relationships with colorectal cancer risk. However, no statistically significant associations were identified. Because common genetic determinants account for only a limited proportion of the variance in circulating adiponectin concentrations, factors that influence adiponectin receptors and other components of the adiponectin pathway should be investigated.

AB Like stem cells in other tissues, spermatogonia, including spermatogonial stem cells (SSCs) at the foundation of differentiation hierarchy, undergo age-related decline in function. The promyelocytic leukemia zinc finger (Plzf) protein plays an essential role in spermatogonia maintenance by preventing their differentiation. To evaluate whether there is an age-related change in Plzf expression, we found that aged mouse testes exhibited a robust "Plzf overexpression" phenotype, in that they showed not only a higher frequency of Plzf-expressing cells but also an increased level of Plzf expression in these cells. Moreover, some Plzf-expressing cells in aged testes even aberrantly appeared in the differentiating spermatogonia compartment, which is usually low or negative for Plzf expression. Importantly, ectopic Plzf expression in F9 cells suppressed retinoic acid (RA)-induced Stra8 activation, a gene required for meiosis initiation. These data, together with our observation of a lack of meiosis-initiating spermatocytes associated with high Plzf-expressing spermatogonia in the aged testes, particularly in the degenerative seminiferous tubules, suggest that age-related increase in Plzf expression represents a novel molecular signature of spermatogonia aging by functionally arresting their differentiation.

AB The standard treatment for patients with locally advanced rectal cancer is preoperative 5-fluorouracil-based chemoradiotherapy followed by total mesorectal excision. However, tumor response to standard dose radiation varies. In this study, we found that miR-622 was increased significantly in ionizing radiation-treated colorectal cancer (CRC) cells compared to the cells cultured with irradiated medium, and persisted stably in surviving cells treated with continuous low-dose radiation. Overexpression of miR-622 induced the radioresistance in vitro. In addition, miR-622 inhibited Rb expression by directly targeting RB1-3'UTR. Overexpression of Rb reversed miR-622-induced radioresistance in vitro. In response to ionizing radiation, the Rb-E2F1-P/CAF complex activated proapoptotic genes. Importantly, miR-622 was highly expressed in tumors of rectal cancer patients with non-regression after standard dose radiotherapy. In conclusion, miR-622 overexpressing cells are induced or selected by radiotherapy, causing in turn radioresistance and poor response to further therapy. MiR-622 is a potential biomarker of responders for radiotherapy and a potential therapeutic target.

AB The expression of epidermal growth factor receptor (EGFR) is an important diagnostic marker for triple-negative breast cancer (TNBC)cells, which lack three hormonal receptors: estrogen and progesterone receptors as well as epidermal growth factor receptor 2. EGFR transactivation can cause drug resistance in many cancers including TNBC, but the mechanism underlying this phenomenon is poorly defined. Here, we demonstrate that insulin treatment induces EGFR activation by stimulating the interaction of EGFR with insulin-like growth factor receptor 1 (IGF-1R) in the MDA-MB-436 TNBC cell line. These cells express low levels of EGFR, while exhibiting high levels of IGF-1R expression and phosphorylation. Low-EGFR-expressing MDA-MB-436 cells show high sensitivity to insulin-stimulated cell growth. Therefore, unexpectedly, insulin stimulation induced EGFR transactivation by regulating its interaction with IGF-1R in low-EGFR-expressing TNBC cells.

AB Although many different accounts of the functions of the default mode network (DMN) have been proposed, few can adequately account for the spectrum of different cognitive functions that utilize this network. The current study used functional magnetic resonance imaging (fMRI) to explore the hypothesis that the role of the DMN in higher order cognition is to allow cognition to be shaped by information from stored representations rather than information in the immediate environment. Using a novel task paradigm, we observed increased BOLD activity in regions of the medial prefrontal cortex and posterior cingulate cortex when individuals made decisions on the location of shapes from the prior trial and decreased BOLD activity when individuals made decisions on the location of shapes on the current trial. These data are inconsistent with views of the DMN as a task-negative system or one that is sensitive only to stimuli with strong personal or emotional ties. Instead the involvement of the DMN when people make decisions about where a shape was, rather than where it is now, supports the hypothesis that the core hubs of the DMN allow cognition to be guided by information other than the immediate perceptual input. We propose that a variety of different forms of higher order thought (such as imagining the future or considering the perspective of another person) engage the DMN because these more complex introspective forms of higher order thought all depend on the capacity for cognition to be shaped by representations that are not present in the external environment.

TI Galectin-8 Ameliorates Murine Autoimmune Ocular Pathology and Promotes a

AB Galectins have emerged as potent immunoregulatory agents that control chronic inflammation through distinct mechanisms. Here, we report that treatment with Galectin-8 (Gal-8), a tandem-repeat member of the galectin family, reduces retinal pathology and prevents photoreceptor cell damage in a murine model of experimental autoimmune uveitis. Gal-8 treatment increased the number of regulatory T cells (Treg) in both the draining lymph node (dLN) and the inflamed retina. Moreover, a greater percentage of Treg cells in the dLN and retina of Gal-8 treated animals expressed the inhibitory coreceptor cytotoxic T lymphocyte antigen (CTLA)-4, the immunosuppressive cytokine IL-10, and the tissue-homing integrin CD103. Treg cells in the retina of Gal-8-treated mice were primarily inducible Treg cells that lack the expression of neuropilin-1. In addition, Gal-8 treatment blunted production of inflammatory cytokines by retinal T helper type (T-H) 1 and T(H)17 cells. The effect of Gal-8 on T cell differentiation and/or function was specific for tissues undergoing an active immune response, as Gal-8 treatment had no effect on T cell populations in the spleen. Given the need for rational therapies for managing human uveitis, Gal-8 emerges as an attractive therapeutic candidate not only for treating retinal autoimmune diseases, but also for other T(H)1-and T(H)17-mediated inflammatory disorders.

AB Human papillomavirus (HPV) has been identified as a necessary factor in the development of pre-invasive and invasive cancers of the lower genital tract, of which cervical cancer is the most prevalent. A molecular understanding of malignant transformation and epidemiologic information has led to the development of many strategies for detection and early intervention. Newer tests for oncogenic subtypes of HPV have made it possible to predict the risk of future development of cervical cancer. This review summarizes the current understanding of HPV related disease and examines the role of HPV testing as a screening tool for cervical cancer. It summarizes the data from prospective and randomized controlled trials on HPV screening from Europe and North America and includes smaller studies from low and middle income countries where cervical cancer is the most common cancer in women.

AB Background: Best supportive care (BSC) as a control arm in clinical trials is poorly defined. We conducted a review to evaluate clinical trials' concordance with published, consensus-based framework for BSC delivery in trials.
Methods: A consensus-based Delphi panel previously identified four key domains of BSC delivery in trials: multidisciplinary care; supportive care documentation; symptom assessment; and symptom management. We reviewed trials including BSC control arms from 2002 to 2014 to assess concordance to BSC standards and to selected items from the CONSORT 2010 guidelines.
Results: Of 408 articles retrieved, we retained 18 after applying exclusion criteria. Overall, trials conformed to the CONSORT guidelines better than the BSC standards (28% vs 16%). One-third of articles offered a detailed description of BSC, 61% reported regular symptom assessment, and 44% reported using validated symptom assessment measures. One-third reported symptom assessment at identical intervals in both arms. None documented evidence-based symptom management. No studies reported educating patients about symptom management or goals of therapy. No studies reported offering access to palliative care specialists.
Conclusions: Reporting of BSC in trials is incomplete, resulting in uncertain internal and external validity. Such studies risk systematically over-estimating the net clinical effect of the comparator arms.

AB Background: Human sarcomas with a poor response to vascular endothelial growth factor-A (VEGF-A) inhibition and radiation therapy (RT) have upregulation of hypoxia-inducible factor 1 alpha (HIF-1 alpha) and HIF-1 alpha target genes. This study examines the addition of the hypoxia-activated chemotherapy TH-302 to VEGF-A inhibition and RT (a.k.a. trimodality therapy).
Methods: Trimodality therapy was examined in two xenograft models and in vitro in tumour endothelial cells and sarcoma cell lines.
Results: In both mouse models, VEGF-A inhibition and radiation showed greater efficacy than either therapy alone in slowing sarcoma growth. When TH-302 was added, this trimodality therapy completely blocked tumour growth with tumours remaining dormant for over 3 months after cessation of therapy. Trimodality therapy caused 2.6- to 6.2-fold more endothelial cell-specific apoptosis than bimodality therapies, and microvessel density and HIF-1 alpha activity were reduced to 11-13% and 13-20% of control, respectively. When trimodality therapy was examined in vitro, increases in DNA damage and apoptosis were much more pronounced in tumour endothelial cells compared with that in sarcoma cells, especially under hypoxia.
Conclusions: The combination of TH-302, VEGF-A inhibition, and RT is highly effective in preclinical models of sarcoma and is associated with increased DNA damage and apoptosis in endothelial cells and decreased HIF-1 alpha activity.

AB Background: MYCN amplification with subsequent MYCN protein overexpression is a powerful indicator of poor prognosis of neuroblastoma patients. Little is known regarding the prognostic significance of the homologous MYC protein expression in neuroblastoma.
Methods: Immunostaining for MYCN and MYC protein was performed on 357 undifferentiated/poorly differentiated neuroblastomas. Results were analysed with other prognostic markers.
Results: Sixty-seven (19%) tumours were MYCN(+), 38 (11%) were MYC(+), and one(0.3%) had both proteins(+). MYCN(+) tumours and MYC(+) tumours were more likely diagnosed in children > 18months with stage4-disease. MYCN(+) tumours were associated with amplified MYCN, Unfavourable Histology (UH), and High-MKI (Mitosis-Karyorrhexis Index). MYC(+) tumours were also frequently UH but not associated with MYCN amplification, and more likely to have low-/intermediate-MKI. Favourable Histology patients without MYC/MYCN expressions exhibited the best survival (N = 167, 89.7 +/- 5.5% 3-year EFS, 97.0 +/- 3.2% 3-year OS), followed by UH patients without MYC/MYCN expressions (N = 84, 63.1 +/- 13.6% 3-year EFS, 83.5 +/- 9.4% 3-year OS). MYCN(+) patients and MYC(+) patients had similar and significantly low (P<0.0001) survivals (46.2 +/- 12.0% 3-year EFS, 63.2 +/- 12.1% 3-year OS and 43.4 +/- 23.1% 3-year EFS, 63.5 +/- 19.2% 3-year OS, respectively). Notably, the prognostic impact imparted by MYC expression was independent from other markers.
Conclusions: In this series, similar to 30% of neuroblastomas had augmented MYCN or MYC expression with dismal survivals. Prospective study of MYC/MYCN protein expression signature as a new biomarker for high-risk neuroblastomas should be conducted.

TI Fasting, but Not Aging, Dramatically Alters the Redox Status of Cysteine
Residues on Proteins in Drosophila melanogaster

AB Altering the redox state of cysteine residues on protein surfaces is an important response to environmental challenges. Although aging and fasting alter many redox processes, the role of cysteine residues is uncertain. To address this, we used a redox proteomic technique, oxidative isotope-coded affinity tags (OxICAT), to assess cysteine-residue redox changes in Drosophila melanogaster during aging and fasting. This approach enabled us to simultaneously identify and quantify the redox state of several hundred cysteine residues in vivo. Cysteine residues within young flies had a bimodal distribution with peaks at similar to 10% and similar to 85% reversibly oxidized. Surprisingly, these cysteine residues did not become more oxidized with age. In contrast, 24 hr of fasting dramatically oxidized cysteine residues that were reduced under fed conditions while also reducing cysteine residues that were initially oxidized. We conclude that fasting, but not aging, dramatically alters cysteine-residue redox status in D. melanogaster.

AB The polymorphism ATG16L1 T300A, associated with increased risk of Crohn's disease, impairs pathogen defense mechanisms including selective autophagy, but specific pathway interactions altered by the risk allele remain unknown. Here, we use perturbational profiling of human peripheral blood cells to reveal that CLEC12A is regulated in an ATG16L1-T300A-dependent manner. Antibacterial autophagy is impaired in CLEC12A-deficient cells, and this effect is exacerbated in the presence of the ATG16L1*300A risk allele. Clec12a(-/-) mice are more susceptible to Salmonella infection, supporting a role for CLEC12A in antibacterial defense pathways in vivo. CLEC12A is recruited to sites of bacterial entry, bacteria-autophagosome complexes, and sites of sterile membrane damage. Integrated genomics identified a functional interaction between CLEC12A and an E3-ubiquitin ligase complex that functions in antibacterial autophagy. These data identify CLEC12A as early adaptor molecule for antibacterial autophagy and highlight perturbational profiling as a method to elucidate defense pathways in complex genetic disease.

AB Many existing and emerging cancer therapies have a significant effect on the cardiovascular health of patients with cancer and cancer survivors. This paper examines current aspects of interdisciplinary cardio-oncology clinical care delivery and education in the United States and outlines how these data provide a platform for future development of the field. We present the results of the nationwide survey on cardio-oncology services, practices, and opinions, conducted among chiefs of cardiology and program directors, which demonstrate ranges of clinical activities and identify significant interest for increased educational opportunities and expert training of cardiovascular physicians in this field. The survey respondents recognized clinical relevance but emphasized lack of national guidelines, lack of funds, and limited awareness and infrastructure as the main challenges for development and growth of cardio-oncology. We discuss potential solutions to unmet needs through interdisciplinary collaboration and the active roles of professional societies and other stakeholders.

AB Evidence of social and behavioral problems preceding the onset of schizophrenia-spectrum psychoses is consistent with a neurodevelopmental model of these disorders. Here we predict that individuals with a first episode of schizophrenia-spectrum psychoses will evidence one of three patterns of premorbid adjustment: an early deficit, a deteriorating pattern, or adequate or good social adjustment. Participants were 164(38% female; 31% black) individuals ages 15-50 with a first episode of schizophrenia-spectrum psychoses. Premorbid adjustment was assessed using the Cannon-Spoor Premorbid Adjustment Scale. We compared the fit of a series of growth mixture models to examine premorbid adjustment trajectories, and found the following 3-class model provided the best fit with: a "stable-poor" adjustment class (54%), a "stable-good" adjustment class (39%), and a "deteriorating" adjustment class (7%). Relative to the "stable-good" class, the "stable-poor" class experienced worse negative symptoms at 1-year follow-up, particularly in the social amotivation domain. This represents the first known growth mixture modeling study to examine premorbid functioning patterns in first-episode schizophrenia-spectrum psychoses. Given that the stable-poor adjustment pattern was most prevalent, detection of social and academic maladjustment as early as childhood may help identify people at increased risk for schizophrenia-spectrum psychoses, potentially increasing feasibility of early interventions.

AB Researchers and clinicians have long noted the overlap among features and high comorbidity of bipolar disorder and borderline personality disorder. The shared features of impulsivity and labile mood in both disorders make them challenging to distinguish. We tested the hypothesis that variables related to goal dysregulation would be uniquely related to risk for mania, while emotion-relevant impulsivity would be related to risk for both disorders. We administered a broad range of measures related to goal regulation traits and impulsivity to 214 undergraduates. Findings confirmed that risk for mania, but not for borderline personality disorder, was related to higher sensitivity to reward and intense pursuit of goals. In contrast, borderline personality disorder symptoms related more strongly than did mania risk with threat sensitivity and with impulsivity in the context of negative affect. Results highlight potential differences and commonalities in mania risk versus borderline personality disorder risk. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB Response to stress is dysregulated in psychosis (PSY). fMRI studies showed hyperactivity in hypothalamus (HYPO), hippocampus (HIPP), amygdala (AMYG), anterior cingulate (ACC), orbital and medial prefrontal (OFC; mPFC) cortices, with some studies reporting sex differences. We predicted abnormal steroid hormone levels in PSY would be associated with sex differences in hyperactivity in HYPO, AMYG, and HIPP, and hypoactivity in PFC and ACC, with more severe deficits in men. We studied 32 PSY cases (50.0% women) and 39 controls (43.6% women) using a novel visual stress challenge while collecting blood. PSY males showed BOLD hyperactivity across all hypothesized regions, including HYPO and ACC by FWE-correction. Females showed hyperactivity in HIPP and AMYG and hypoactiviLy in OFC and mPFC, the latter FWE-corrected. Interaction of group by sex was significant in mPFC (F=7.00, p=0.01), with PSY females exhibiting the lowest activity. Male hyperactivity in HYPO and ACC was significantly associated with hypercortisolemia post-stress challenge, and mPFC with low androgens. Steroid hormones and neural activity were dissociated in PSY women. Findings suggest disruptions in neural circuitry -hormone associations in response to stress are sex-dependent in psychosis, particularly in prefrontal cortex. (C) 2015 Elsevier Ireland Ltd.

AB Background: Retention in HIV care improves survival and reduces the risk of HIV transmission to others. Multiple quantitative studies have described demographic and clinical characteristics associated with retention in HIV care. However, qualitative studies are needed to better understand barriers and facilitators.
Methods: Semi-structured interviews were conducted with 51 HIV-infected individuals, 25 who were retained in care and 26 not retained in care, from 3 urban clinics. Interview data were analyzed for themes using a modified grounded theory approach. Identified themes were compared between the two groups of interest: patients retained in care and those not retained in care.
Results: Overall, participants identified 12 barriers and 5 facilitators to retention in HIV care. On average, retained individuals provided 3 barriers, while persons not retained in care provided 5 barriers. Both groups commonly discussed depression/mental illness, feeling sick, and competing life activities as barriers. In addition, individuals not retained in care commonly reported expensive and unreliable transportation, stigma, and insufficient insurance as barriers. On average, participants in both groups referenced 2 facilitators, including the presence of social support, patient-friendly clinic services (transportation, co-location of services, scheduling/reminders), and positive relationships with providers and clinic staff.
Conclusions: In our study, patients not retained in care faced more barriers, particularly social and structural barriers, than those retained in care. Developing care models where social and financial barriers are addressed, mental health and substance abuse treatment is integrated, and patient-friendly services are offered is important to keeping HIV-infected individuals engaged in care.

AB Background: Autism spectrum disorders (ASD) are increasingly prevalent and have a significant impact on the lives of patients and their families. Currently, the diagnosis is determined by clinical judgment and no definitive physiological biomarker for ASD exists. Quantitative biomarkers obtainable from clinical neuroimaging data - such as the scalp electroencephalogram (EEG) - would provide an important aid to clinicians in the diagnosis of ASD. The interpretation of prior studies in this area has been limited by mixed results and the lack of validation procedures. Here we use retrospective clinical data from a well-characterized population of children with ASD to evaluate the rhythms and coupling patterns present in the EEG to develop and validate an electrophysiological biomarker of ASD.
Methods: EEG data were acquired from a population of ASD (n = 27) and control (n = 55) children 4-8 years old. Data were divided into training (n = 13 ASD, n = 24 control) and validation (n = 14 ASD, n = 31 control) groups. Evaluation of spectral and functional network properties in the first group of patients motivated three biomarkers that were computed in the second group of age-matched patients for validation.
Results: Three biomarkers of ASD were identified in the first patient group: (1) reduced posterior/anterior power ratio in the alpha frequency range (8-14 Hz), which we label the "peak alpha ratio", (2) reduced global density in functional networks, and (3) a reduction in the mean connectivity strength of a subset of functional network edges. Of these three biomarkers, the first and third were validated in a second group of patients. Using the two validated biomarkers, we were able to classify ASD subjects with 83 % sensitivity and 68 % specificity in a post-hoc analysis.
Conclusions: This study demonstrates that clinical EEG can provide quantitative biomarkers to assist diagnosis of autism. These results corroborate the general finding that ASD subjects have decreased alpha power gradients and network connectivities compared to control subjects. In addition, this study demonstrates the necessity of using statistical techniques to validate EEG biomarkers identified using exploratory methods.

AB Trehalose is a naturally occurring disaccharide which is associated with extraordinary stress-tolerance capacity in certain species of unicellular and multicellular organisms. In mammalian cells, presence of intra- and extracellular trehalose has been shown to confer improved tolerance against freezing and desiccation. Since mammalian cells do not synthesize nor import trehalose, the development of novel methods for efficient intracellular delivery of trehalose has been an ongoing investigation. Herein, we studied the membrane permeability of engineered lipophilic derivatives of trehalose. Trehalose conjugated with 6 acetyl groups (trehalose hexaacetate or 6-O-Ac-Tre) demonstrated superior permeability in rat hepatocytes compared with regular trehalose, trehalose diacetate (2-O-Ac-Tre) and trehalose tetraacetate (4-O-Ac-Tre). Once in the cell, intracellular esterases hydrolyzed the 6-O-Ac-Tre molecules, releasing free trehalose into the cytoplasm. The total concentration of intracellular trehalose (plus acetylated variants) reached as high as 10 fold the extracellular concentration of 6-O-Ac-Tre, attaining concentrations suitable for applications in biopreservation. To describe this accumulation phenomenon, a diffusion-reaction model was proposed and the permeability and reaction kinetics of 6-O-Ac-Tre were determined by fitting to experimental data. Further studies suggested that the impact of the loading and the presence of intracellular trehalose on cellular viability and function were negligible. Engineering of trehalose chemical structure rather than manipulating the cell, is an innocuous, cell-friendly method for trehalose delivery, with demonstrated potential for trehalose loading in different types of cells and cell lines, and can facilitate the wide-spread application of trehalose as an intracellular protective agent in biopreservation studies.

AB Background: Gene expression profiling is being widely applied in cancer research to identify biomarkers for clinical endpoint prediction. Since RNA-seq provides a powerful tool for transcriptome-based applications beyond the limitations of microarrays, we sought to systematically evaluate the performance of RNA-seq-based and microarray-based classifiers in this MAQC-III/SEQC study for clinical endpoint prediction using neuroblastoma as a model.
Results: We generate gene expression profiles from 498 primary neuroblastomas using both RNA-seq and 44 k microarrays. Characterization of the neuroblastoma transcriptome by RNA-seq reveals that more than 48,000 genes and 200,000 transcripts are being expressed in this malignancy. We also find that RNA-seq provides much more detailed information on specific transcript expression patterns in clinico-genetic neuroblastoma subgroups than microarrays. To systematically compare the power of RNA-seq and microarray-based models in predicting clinical endpoints, we divide the cohort randomly into training and validation sets and develop 360 predictive models on six clinical endpoints of varying predictability. Evaluation of factors potentially affecting model performances reveals that prediction accuracies are most strongly influenced by the nature of the clinical endpoint, whereas technological platforms (RNA-seq vs. microarrays), RNA-seq data analysis pipelines, and feature levels (gene vs. transcript vs. exon-junction level) do not significantly affect performances of the models.
Conclusions: We demonstrate that RNA-seq outperforms microarrays in determining the transcriptomic characteristics of cancer, while RNA-seq and microarray-based models perform similarly in clinical endpoint prediction. Our findings may be valuable to guide future studies on the development of gene expression-based predictive models and their implementation in clinical practice.

AB Novel therapies for chronic graft-versus-host disease (cGVHD) are needed. Aberrant B-cell activation has been demonstrated in mice and humans with cGVHD. Having previously found that human cGVHD B cells are activated and primed for survival, we sought to further evaluate the role of the spleen tyrosine kinase (Syk) in cGVHD in multiple murine models and human peripheral blood cells. In a murine model of multiorgan system, non-sclerodermatous disease with bronchiolitis obliterans where cGVHD is dependent on antibody and germinal center (GC) B cells, we found that activation of Syk was necessary in donor B cells, but not T cells, for disease progression. Bone marrow-specific Syk deletion in vivo was effective in treating established cGVHD, as was a small-molecule inhibitor of Syk, fostamatinib, which normalized GC formation and decreased activated CD80/86(+) dendritic cells. In multiple distinct models of sclerodermatous cGVHD, clinical and pathological disease manifestations were not eliminated when mice were therapeutically treated with fostamatinib, though both clinical and immunologic effects could be observed in one of these scleroderma models. We further demonstrated that Syk inhibition was effective at inducing apoptosis of human cGVHD B cells. Together, these data demonstrate a therapeutic potential of targeting B-cell Syk signaling in cGVHD.

TI Loss of Resting-State Posterior Cingulate Flexibility Is Associated with
Memory Disturbance in Left Temporal Lobe Epilepsy
SO PLOS ONE

AB The association between cognition and resting-state fMRI (rs-fMRI) has been the focus of many recent studies, most of which use stationary connectivity. The dynamics or flexibility of connectivity, however, may be seminal for understanding cognitive functioning. In temporal lobe epilepsy (TLE), stationary connectomic correlates of impaired memory have been reported mainly for the hippocampus and posterior cingulate cortex (PCC). We therefore investigate resting-state and task-based hippocampal and PCC flexibility in addition to stationary connectivity in left TLE (LTLE) patients. Sixteen LTLE patients were analyzed with respect to rs-fMRI and task-based fMRI (t-fMRI), and underwent clinical neuropsychological testing. Flexibility of connectivity was calculated using a sliding-window approach by determining the standard deviation of Fisher-transformed Pearson correlation coefficients over all windows. Stationary connectivity was also calculated. Disturbed memory was operationalized as having at least one memory subtest score equal to or below the 5th percentile compared to normative data. Lower PCC flexibility, particularly in the contralateral (i.e. right) hemisphere, was found in memory-disturbed LTLE patients, who had up to 22% less flexible connectivity. No significant group differences were found with respect to hippocampal flexibility, stationary connectivity during both rs-fMRI and t-fMRI, or flexibility during t-fMRI. Contralateral resting-state PCC flexibility was able to classify all but one patient with respect to their memory status (94% accuracy). Flexibility of the PCC during rest relates to memory functioning in LTLE patients. Loss of flexible connectivity to the rest of the brain originating from the PCC, particularly contralateral to the seizure focus, is able to discern memory disturbed patients from their preserved counterparts. This study indicates that the dynamics of resting-state connectivity are associated with cognitive status of LTLE patients, rather than stationary connectivity.

AB HIV-1 immunotherapy with a combination of first generation monoclonal antibodies was largely ineffective in pre-clinical and clinical settings and was therefore abandoned(1-3). However, recently developed single-cell-based antibody cloning methods have uncovered a new generation of far more potent broadly neutralizing antibodies to HIV-1 (refs 4, 5). These antibodies can prevent infection and suppress viraemia in humanized mice and nonhuman primates, but their potential for human HIV-1 immunotherapy has not been evaluated(6-10). Here we report the results of a first-in-man dose escalation phase 1 clinical trial of 3BNC117, a potent human CD4 binding site antibody(11), in uninfected and HIV-1-infected individuals. 3BNC117 infusion was well tolerated and demonstrated favourable pharmacokinetics. A single 30mg kg(-1) infusion of 3BNC117 reduced the viral load in HIV-1-infected individuals by 0.8-2.5 log(10) and viraemia remained significantly reduced for 28 days. Emergence of resistant viral strains was variable, with some individuals remaining sensitive to 3BNC117 for a period of 28 days. We conclude that, as a single agent, 3BNC117 is safe and effective in reducing HIV-1 viraemia, and that immunotherapy should be explored as a new modality for HIV-1 prevention, therapy and cure.

AB We generated F-18-labeled antibody fragments for positron emission tomography (PET) imaging using a sortase-mediated reaction to install a trans-cyclooctene-functionalized short peptide onto proteins of interest, followed by reaction with a tetrazine-labeled-F-18-2-deoxyfluoroglucose (FDG). The method is rapid, robust, and site-specific (radiochemical yields > 25%, not decay corrected). The availability of F-18-2-deoxyfluoroglucose avoids the need for more complicated chemistries used to generate carbon-fluorine bonds. We demonstrate the utility of the method by detecting heterotopic pancreatic tumors in mice by PET, using anti-Class II MHC single domain antibodies. We correlate macroscopic PET images with microscopic two-photon visualization of the tumor. Our approach provides easy access to F-18-labeled antibodies and their fragments at a level of molecular specificity that complements conventional F-18-FDG imaging.

AB Understanding the spatiotemporal dynamics of brain activity is crucial for inferring the underlying synaptic and nonsynaptic mechanisms of brain dysfunction. Focal seizures with secondary generalization are traditionally considered to begin in a limited spatial region and spread to connected areas, which can include both pathological and normal brain tissue. The mechanisms underlying this spread are important to our understanding of seizures and to improve therapies for surgical intervention. Here we study the properties of seizure recruitment-how electrical brain activity transitions to large voltage fluctuations characteristic of spike-and-wave seizures. We do so using invasive subdural electrode arrays from a population of 16 patients with pharmacoresistant epilepsy. We find an average delay of similar to 30 s for a broad area of cortex (8 x 8 cm) to be recruited into the seizure, at an estimated speed of similar to 4 mm/s. The spatiotemporal characteristics of recruitment reveal two categories of patients: one in which seizure recruitment of neighboring cortical regions follows a spatially organized pattern consistent from seizure to seizure, and a second group without consistent spatial organization of activity during recruitment. The consistent, organized recruitment correlates with a more regular, compared with small-world, connectivity pattern in simulation and successful surgical treatment of epilepsy. We propose that an improved understanding of how the seizure recruits brain regions into large amplitude voltage fluctuations provides novel information to improve surgical treatment of epilepsy and highlights the slow spread of massive local activity across a vast extent of cortex during seizure.

AB Background: Here we present a non-invasive imaging method for visualizing endogenous enzyme activities in living animals. This optical imaging method is based on an energy transfer principle termed chemically initiated electron exchange luminescence (CIEEL). The light energy is provided by enzymatic activation of metastable 1,2-dioxetane substrates, whose protective groups are removed by hydrolytic enzymes such as beta-galactosidase and alkaline phosphatase. In the presence of a nearby fluorescent recipient, the chemical energy within the activated substrate is then transferred via formation of a charge-transfer complex with the fluorophore, a mechanism closely related to glow stick chemistry.
Results: Efficient CIEEL energy transfer requires close proximity between the trigger enzyme and the fluorescent recipient. Using cells stained with fluorescent dialkylcarbocyanines as the energy recipients, we demonstrated CIEEL imaging of cellular beta-galactosidase or alkaline phosphatase activity. In living animals, we used a similar approach to non-invasively image alkaline phosphatase activity in the peritoneal cavity.
Conclusions: In this report, we provide proof-of-concept for CIEEL imaging of in vivo enzymatic activity. In addition, we demonstrate the use of CIEEL energy transfer for visualizing elevated alkaline phosphatase activity associated with tissue inflammation in living animals.

AB Electroencephalogram (EEG) approaches may provide important information about developmental changes in brain-state dynamics during general anesthesia. We used multi-electrode EEG, analyzed with multitaper spectral methods and video recording of body movement to characterize the spatio-temporal dynamics of brain activity in 36 infants 0-6 months old when awake, and during maintenance of and emergence from sevoflurane general anesthesia. During maintenance: (1) slow-delta oscillations were present in all ages; (2) theta and alpha oscillations emerged around 4 months; (3) unlike adults, all infants lacked frontal alpha predominance and coherence. Alpha power was greatest during maintenance, compared to awake and emergence in infants at 4-6 months. During emergence, theta and alpha power decreased with decreasing sevoflurane concentration in infants at 4-6 months. These EEG dynamic differences are likely due to developmental factors including regional differences in synaptogenesis, glucose metabolism, and myelination across the cortex. We demonstrate the need to apply age-adjusted analytic approaches to develop neurophysiologic-based strategies for pediatric anesthetic state monitoring.

AB Impaired gating of the auditory evoked P50 potential is one of the most pharmacologically well-characterized features of schizophrenia. This deficit is most commonly modeled in rodents by implanted electrode recordings from the hippocampus of the rodent analog of the P50, the P20-N40. The validity and effectiveness of this tool, however, has not been systematically reviewed. Here, we summarize findings from studies that have examined the effects of pharmacologic modulation on gating of the rodent hippocampal P20-N40 and the human P50. We show that drug effects on the P20-N40 are highly predictive of human effects across similar dose ranges. Furthermore, mental status (for example, anesthetized vs alert) does not appear to diminish the predictive capacity of these recordings. We then discuss hypothesized neuropharmacologic mechanisms that may underlie gating effects for each drug studied. Overall, this review supports continued use of hippocampal P20-N40 gating as a translational tool for schizophrenia research.

AB Background Biomarkers that predict response to cardiac resynchronization therapy (CRT) in heart failure patients with dyssynchrony (HFDYS) would be clinically important. Circulating extracellular microRNAs (miRNAs) have emerged as novel biomarkers that may also play important functional roles, but their relevance as markers for CRT response has not been examined.
Methods and Results Comprehensive miRNA polymerase chain reaction arrays were used to assess baseline levels of 766 plasma miRNAs in patients undergoing clinically indicated CRT in an initial discovery set (n=12) with and without subsequent echocardiographic improvement at 6 months after CRT. Validation of candidate miRNAs in 61 additional patients confirmed that baseline plasma miR-30d was associated with CRT response (defined as an increase in left ventricular ejection fraction 10%). MiR-30d was enriched in coronary sinus blood and increased in late-contracting myocardium in a canine model of HFDYS, indicating cardiac origin with maximal expression in areas of high mechanical stress. We examined the functional effects of miR-30d in cultured cardiomyocytes and determined that miR-30d is expressed in cardiomyocytes and released in vesicles in response to mechanical stress. Overexpression of miR-30d in cultured cardiomyocytes led to cardiomyocyte growth and protected against apoptosis by targeting the mitogen-associated kinase 4, a downstream effector of tumor necrosis factor. In HFDYS patients, miR-30d plasma levels inversely correlated with high-sensitivity troponin T, a marker of myocardial necrosis.
Conclusions Baseline plasma miR-30d level is associated with response to CRT in HFDYS in this translational pilot study. MiR-30d increase in cardiomyocytes correlates with areas of increased wall stress in HFDYS and is protective against deleterious tumor necrosis factor signaling.

TI Neural population dynamics in human motor cortex during movements in
people with ALS
SO ELIFE

DT Article
ID ARM MOVEMENTS; TETRAPLEGIA
AB The prevailing view of motor cortex holds that motor cortical neural activity represents muscle or movement parameters. However, recent studies in non-human primates have shown that neural activity does not simply represent muscle or movement parameters; instead, its temporal structure is well-described by a dynamical system where activity during movement evolves lawfully from an initial pre-movement state. In this study, we analyze neuronal ensemble activity in motor cortex in two clinical trial participants diagnosed with Amyotrophic Lateral Sclerosis (ALS). We find that activity in human motor cortex has similar dynamical structure to that of non-human primates, indicating that human motor cortex contains a similar underlying dynamical system for movement generation.

AB Proprotein convertase subtilisin/kexin type 9 (PCSK9) binds to the low-density lipoprotein receptor, escorting it to its destruction in the lysosome and thereby preventing the recirculation of the low-density lipoprotein receptor to the hepatocyte cell surface. Both gain-of-function mutations in PCSK9 (causing marked increases in low-density lipoprotein cholesterol [LDL-C] concentration and premature atherosclerosis) and loss-of-function mutations (causing modest LDL-C reduction with low rates of coronary heart disease) have been described. Several monoclonal antibodies to PCSK9 have achieved LDL-C reductions of 50% to 70% across various patient populations and background lipid therapies. Phase 2/3 trials have demonstrated good tolerability without clear drug-related toxicity, although the number and duration of patients treated to date is modest. Currently, 4 phase 3 trials involving >70,000 patients are testing whether these drugs reduce cardiovascular events. The U.S. Food and Drug Administration is currently reviewing the existing data to determine whether these agents could be made available prior to the completion of these cardiovascular endpoint trials expected in 2018.

AB Despite the rapid accumulation of tumor-profiling data and transcription factor (TF) ChIP-seq profiles, efforts integrating TF binding with the tumor-profiling data to understand how TFs regulate tumor gene expression are still limited. To systematically search for cancer-associated TFs, we comprehensively integrated 686 ENCODE ChIP-seq profiles representing 150 TFs with 7484 TCGA tumor data in 18 cancer types. For efficient and accurate inference on gene regulatory rules across a large number and variety of datasets, we developed an algorithm, RABIT (regression analysis with background integration). In each tumor sample, RABIT tests whether the TF target genes from ChIP-seq show strong differential regulation after controlling for background effect from copy number alteration and DNA methylation. When multiple ChIP-seq profiles are available for a TF, RABIT prioritizes the most relevant ChIP-seq profile in each tumor. In each cancer type, RABIT further tests whether the TF expression and somatic mutation variations are correlated with differential expression patterns of its target genes across tumors. Our predicted TF impact on tumor gene expression is highly consistent with the knowledge from cancer-related gene databases and reveals many previously unidentified aspects of transcriptional regulation in tumor progression. We also applied RABIT on RNA-binding protein motifs and found that some alternative splicing factors could affect tumor-specific gene expression by binding to target gene 3'UTR regions. Thus, RABIT (rabit.dfci.harvard.edu) is a general platform for predicting the oncogenic role of gene expression regulators.

AB Beneficial microbes that target molecules and pathways, such as oxidative stress, which can negatively affect both host and microbiota, may hold promise as an inflammatory bowel disease therapy. Prior work showed that a five-strain fermented milk product (FMP) improved colitis in T-bet(-/-) Rag2(-/-) mice. By varying the number of strains used in the FMP, we found that Lactococcus lactis I-1631 was sufficient to ameliorate colitis. Using comparative genomic analyses, we identified genes unique to L. lactis I-1631 involved in oxygen respiration. Respiration of oxygen results in reactive oxygen species (ROS) generation. Also, ROS are produced at high levels during intestinal inflammation and cause tissue damage. L. lactis I-1631 possesses genes encoding enzymes that detoxify ROS, such as superoxide dismutase (SodA). Thus, we hypothesized that lactococcal SodA played a role in attenuating colitis. Inactivation of the sodA gene abolished L. lactis I-1631' s beneficial effect in the T-bet(-/-) Rag2(-/-) model. Similar effects were obtained in two additional colonic inflammation models, Il10(-/-) mice and dextran sulfate sodium-treated mice. Efforts to understand how a lipophobic superoxide anion (O-2(-)) can be detoxified by cytoplasmic lactoccocal SodA led to the finding that host antimicrobial-mediated lysis is a prerequisite for SodA release and SodA's extracytoplasmic O-2(-) scavenging. L. lactis I-1631 may represent a promising vehicle to deliver antioxidant, colitis-attenuating SodA to the inflamed intestinal mucosa, and host antimicrobials may play a critical role in mediating SodA's bioaccessibility.

AB Ligands stimulate Notch receptors by inducing regulated intramembrane proteolysis (RIP) to produce a transcriptional effector. Notch activation requires unmasking of a metalloprotease cleavage site remote from the site of ligand binding, raising the question of how proteolytic sensitivity is achieved. Here, we show that application of physiologically relevant forces to the Notch1 regulatory switch results in sensitivity to metalloprotease cleavage, and bound ligands induce Notch signal transduction in cells only in the presence of applied mechanical force. Synthetic receptor-ligand systems that remove the native ligand-receptor interaction also activate Notch by inducing proteolysis of the regulatory switch. Together, these studies show that mechanical force exerted by signal-sending cells is required for ligand-induced Notch activation and establish that force-induced proteolysis can act as a mechanism of cellular mechanotransduction.

AB The link between African-Americans' disproportionate rates of diabetes, obesity and vitamin D deficiency may be marked by C-peptide as an indicator of insulin secretion. We hypothesize that vitamin D supplementation will increase C-peptide, a marker of insulin secretion. During 3 winters from 2007-2010, 328 healthy African-Americans (median age, 51 years) living in Boston, MA were randomized into a 4-arm, double-blind trial for 3 months of placebo, 1000, 2000, or 4000 IU of vitamin D3. The differences in non-fasting C-peptide between baseline and 3 months were -0.44 ng/mL for those receiving placebo, -0.10 ng/mL for those receiving 1000 IU/d, 0 ng/mL for those receiving 2000 IU/d, 1.24 ng/mL for those receiving 4000 IU/d (C-peptide increased 0.42 ng/mL for each additional 1000 IU/d of vitamin D3, p < 0.001). Vitamin D supplementation increased C-peptide in overweight African-Americans and may be compatible with other recommendations for diabetes prevention and management including weight loss and increased physical activity.

AB Aims The effect of statins on risk of heart failure (HF) hospitalization and HF death remains uncertain. We aimed to establish whether statins reduce major HF events.
Methods and results We searched Medline, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized controlled endpoint statin trials from 1994 to 2014. Collaborating trialists provided unpublished data from adverse event reports. We included primary- and secondary-prevention statin trials with >1000 participants followed for >1 year. Outcomes consisted of first on-fatal HF hospitalization, HF death and a composite of first non-fatal HF hospitalization or HF death. HF events occurring <30 days after within-trial myocardial infarction (MI) were excluded. We calculated risk ratios (RR) with fixed-effects meta-analyses. In up to 17 trials with 132 538 participants conducted over 4.3 [weighted standard deviation (SD) 1.4] years, statin therapy reduced LDL-cholesterol by 0.97 mmol/L (weighted SD 0.38 mmol/L). Statins reduced the numbers of patients experiencing non-fatal HF hospitalization (1344/66 238 vs. 1498/66 330; RR 0.90, 95% confidence interval, CI 0.84-0.97) and the composite HF outcome (1234/57 734 vs. 1344/57 836; RR 0.92, 95% CI 0.85-0.99) but not HF death (213/57 734 vs. 220/57 836; RR0.97,95% CI 0.80-1.17). The effect of statins on first non-fatal HF hospitalization was similar whether this was preceded by MI (RR 0.87, 95% CI 0.68-1.11) or not (RR 0.91, 95% CI 0.84-0.98).
Conclusion In primary- and secondary-prevention trials, statins modestly reduced the risks of non-fatal HF hospitalization and a composite of non-fatal HF hospitalization and HF death with no demonstrable difference in risk reduction between those who suffered an MI or not.

AB Kilo-voltage (KV) cone-beam computed tomography (CBCT) unit mounted onto a linear accelerator treatment system, often referred to as on-board imager (OBI), plays an increasingly important role in image-guided radiation therapy. While the FDK algorithm is currently used for reconstructing images from clinical OBI data, optimization-based reconstruction has also been investigated for OBI CBCT. An optimization-based reconstruction involves numerous parameters, which can significantly impact reconstruction properties (or utility). The success of an optimization-based reconstruction for a particular class of practical applications thus relies strongly on appropriate selection of parameter values. In the work, we focus on tailoring the constrained-TVminimization- based reconstruction, an optimization-based reconstruction previously shown of some potential for CBCT imaging conditions of practical interest, to OBI imaging through appropriate selection of parameter values. In particular, for given real data of phantoms and patient collected with OBI CBCT, we first devise utility metrics specific to OBI-quality-assurance tasks and then apply them to guiding the selection of parameter values in constrained-TV-minimization-based reconstruction. The study results show that the reconstructions are with improvement, relative to clinical FDK reconstruction, in both visualization and quantitative assessments in terms of the devised utility metrics.

AB Chemical exchange saturation transfer (CEST) MRI has been increasingly applied to detect dilute solutes and physicochemical properties, with promising in vivo applications. Whereas CEST imaging has been implemented with continuous wave (CW) radio-frequency irradiation on preclinical scanners, pulse-train irradiation is often chosen on clinical systems. Therefore, it is necessary to optimize pulse-train CEST imaging, particularly important for translational studies. Because conventional Bloch-McConnell formulas are not in the form of homogeneous differential equations, the routine simulation approach simulates the evolving magnetization step by step, which is time consuming. Herein we developed a computationally efficient numerical solution using matrix iterative analysis of homogeneous Bloch-McConnell equations. The proposed algorithm requires simulation of pulse-train CEST MRI magnetization within one irradiation repeat, with 99% computation time reduction from that of conventional approach under typical experimental conditions. The proposed solution enables determination of labile proton ratio and exchange rate from pulse- train CEST MRI experiment, within 5% from those determined from quantitative CW-CEST MRI. In addition, the structural similarity index analysis shows that the dependence of CEST contrast on saturation pulse flip angle and duration between simulation and experiment was 0.98 +/- 0.01, indicating that the proposed simulation algorithm permits fast optimization and quantification of pulse-train CEST MRI.

AB Significance: An ancient anionic phospholipid, cardiolipin (CL), ubiquitously present in prokaryotic and eukaryotic membranes, is essential for several structural and functional purposes. Recent Advances: The emerging role of CLs in signaling has become the focus of many studies. Critical Issues: In this work, we describe two major pathways through which mitochondrial CLs may fulfill the signaling functions via utilization of their (i) asymmetric distribution across membranes and translocations, leading to the surface externalization and (ii) ability to undergo oxidation reactions to yield the signature products recognizable by the executionary machinery of cells. Future Directions: We present a concept that CLs and their oxidation/hydrolysis products constitute a rich communication language utilized by mitochondria of eukaryotic cells for diversified regulation of cell physiology and metabolism as well as for inter-cellular interactions.

TUMORS; PHASE-III; B7 FAMILY; MELANOMA; GUIDELINES; DOCETAXEL; BLOCKADE
AB Purpose
Programmed death 1 is an immune checkpoint that suppresses antitumor immunity. Nivolumab, a fully human immunoglobulin G4 programmed death 1 immune checkpoint inhibitor antibody, was active and generally well tolerated in patients with advanced solid tumors treated in a phase I trial with expansion cohorts. We report overall survival (OS), response durability, and long-term safety in patients with non-small-cell lung cancer (NSCLC) receiving nivolumab in this trial.
Patients and Methods
Patients (N = 129) with heavily pretreated advanced NSCLC received nivolumab 1, 3, or 10 mg/kg intravenously once every 2 weeks in 8-week cycles for up to 96 weeks. Tumor burden was assessed by RECIST (version 1.0) after each cycle.
Results
Median OS across doses was 9.9 months; 1-, 2-, and 3-year OS rates were 42%, 24%, and 18%, respectively, across doses and 56%, 42%, and 27%, respectively, at the 3-mg/kg dose (n = 37) chosen for further clinical development. Among 22 patients (17%) with objective responses, estimated median response duration was 17.0 months. An additional six patients (5%) had unconventional immune-pattern responses. Response rates were similar in squamous and nonsquamous NSCLC. Eighteen responding patients discontinued nivolumab for reasons other than progressive disease; nine (50%) of those had responses lasting > 9 months after their last dose. Grade 3 to 4 treatment-related adverse events occurred in 14% of patients. Three treatment-related deaths (2% of patients) occurred, each associated with pneumonitis.
Conclusion
Nivolumab monotherapy produced durable responses and encouraging survival rates in patients with heavily pretreated NSCLC. Randomized clinical trials with nivolumab in advanced NSCLC are ongoing.

AB Purpose
Blockade of the programmed death-1 inhibitory cell-surface molecule on immune cells using the fully human immunoglobulin G4 antibody nivolumab mediates tumor regression in a portion of patients with advanced treatment-refractory solid tumors. We report clinical activity, survival, and long-term safety in patients with advanced renal cell carcinoma (RCC) treated with nivolumab in a phase I study with expansion cohorts.
Patients and Methods
A total of 34 patients with previously treated advanced RCC, enrolled between 2008 and 2012, received intravenous nivolumab (1 or 10 mg/kg) in an outpatient setting once every two weeks for up to 96 weeks and were observed for survival and duration of response after treatment discontinuation.
Results
Ten patients (29%) achieved objective responses (according to RECIST [version 1.0]), with median response duration of 12.9 months; nine additional patients (27%) demonstrated stable disease lasting > 24 weeks. Three of five patients who stopped treatment while in response continued to respond for 45 weeks. Median overall survival in all patients (71% with two to five prior systemic therapies) was 22.4 months; 1-, 2-, and 3-year survival rates were 71%, 48%, and 44%, respectively. Grade 3 to 4 treatment-related adverse events occurred in 18% of patients; all were reversible.
Conclusion
Patients with advanced treatment-refractory RCC treated with nivolumab demonstrated durable responses that in some responders persisted after drug discontinuation. Overall survival is encouraging, and toxicities were generally manageable. Ongoing randomized clinical trials will further assess the impact of nivolumab on overall survival in patients with advanced RCC.

TI Risk Algorithm Using Serial Biomarker Measurements Doubles the Number of
Screen-Detected Cancers Compared With a Single-Threshold Rule in the
United Kingdom Collaborative Trial of Ovarian Cancer Screening
SO JOURNAL OF CLINICAL ONCOLOGY
LA English

IMPACT; ROCA
AB Purpose
Cancer screening strategies have commonly adopted single-biomarker thresholds to identify abnormality. We investigated the impact of serial biomarker change interpreted through a risk algorithm on cancer detection rates.
Patients and Methods
In the United Kingdom Collaborative Trial of Ovarian Cancer Screening, 46,237 women, age 50 years or older underwent incidence screening by using the multimodal strategy (MMS) in which annual serum cancer antigen 125 (CA-125) was interpreted with the risk of ovarian cancer algorithm (ROCA). Women were triaged by the ROCA: normal risk, returned to annual screening; intermediate risk, repeat CA-125; and elevated risk, repeat CA-125 and transvaginal ultrasound. Women with persistently increased risk were clinically evaluated. All participants were followed through national cancer and/or death registries. Performance characteristics of a single-threshold rule and the ROCA were compared by using receiver operating characteristic curves.
Results
After 296,911 women-years of annual incidence screening, 640 women underwent surgery. Of those, 133 had primary invasive epithelial ovarian or tubal cancers (iEOCs). In all, 22 interval iEOCs occurred within 1 year of screening, of which one was detected by ROCA but was managed conservatively after clinical assessment. The sensitivity and specificity of MMS for detection of iEOCs were 85.8% (95% CI, 79.3% to 90.9%) and 99.8% (95% CI, 99.8% to 99.8%), respectively, with 4.8 surgeries per iEOC. ROCA alone detected 87.1% (135 of 155) of the iEOCs. Using fixed CA-125 cutoffs at the last annual screen of more than 35, more than 30, and more than 22 U/mL would have identified 41.3% (64 of 155), 48.4% (75 of 155), and 66.5% (103 of 155), respectively. The area under the curve for ROCA (0.915) was significantly (P = .0027) higher than that for a single-threshold rule (0.869).
Conclusion
Screening by using ROCA doubled the number of screen-detected iEOCs compared with a fixed cutoff. In the context of cancer screening, reliance on predefined single-threshold rules may result in biomarkers of value being discarded. (C) 2015 American Society of Clinical Oncology.

AB Genital Chlamydia trachomatis (Ct) infection induces protective immunity that depends on interferon-g-producing CD4 T cells. By contrast, we report that mucosal exposure to ultraviolet light (UV)-inactivated Ct (UV-Ct) generated regulatory T cells that exacerbated subsequent Ct infection. We show that mucosal immunization with UV-Ct complexed with charge-switching synthetic adjuvant particles (cSAPs) elicited long-lived protection in conventional and humanized mice. UV-Ct-cSAP targeted immunogenic uterine CD11b(+)CD103(-) dendritic cells (DCs), whereas UV-Ct accumulated in tolerogenic CD11b(-)CD103(+) DCs. Regardless of vaccination route, UV-Ct-cSAP induced systemic memory T cells, but only mucosal vaccination induced effector T cells that rapidly seeded uterine mucosa with resident memory T cells (T-RM cells). Optimal Ct clearance required both TRM seeding and subsequent infection-induced recruitment of circulating memory T cells. Thus, UV-Ct-cSAP vaccination generated two synergistic memory T cell subsets with distinct migratory properties.

TI Cost-effectiveness of first-line antiretroviral therapy for HIV-infected
African children less than 3 years of age
SO AIDS
LA English
DT Article
DE Africa; cost-effectiveness; first-line antiretroviral therapy; IMPAACT;
P1060 trial; pediatric HIV
AB Background:The International Maternal, Pediatric, and Adolescent Clinical Trials P1060 trial demonstrated superior outcomes for HIV-infected children less than 3 years old initiating antiretroviral therapy (ART) with lopinavir/ritonavir compared to nevirapine, but lopinavir/ritonavir is four-fold costlier.Design/methods:We used the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Pediatric model, with published and P1060 data, to project outcomes under three strategies: no ART; first-line nevirapine (with second-line lopinavir/ritonavir); and first-line lopinavir/ritonavir (second-line nevirapine). The base-case examined South African children initiating ART at age 12 months; sensitivity analyses varied all key model parameters. Outcomes included life expectancy, lifetime costs, and incremental cost-effectiveness ratios [ICERs; dollars/year of life saved ($/YLS)]. We considered interventions with ICERs less than 1x per-capita gross domestic product (South Africa: $7500)/YLS as very cost-effective,' interventions with ICERs below 3x gross domestic product/YLS as cost-effective,' and interventions leading to longer life expectancy and lower lifetime costs as cost-saving'.Results:Projected life expectancy was 2.8 years with no ART. Both ART regimens markedly improved life expectancy and were very cost-effective, compared to no ART. First-line lopinavir/ritonavir led to longer life expectancy (28.8 years) and lower lifetime costs ($41350/person, from lower second-line costs) than first-line nevirapine (27.6 years, $44030). First-line lopinavir/ritonavir remained cost-saving or very cost-effective compared to first-line nevirapine unless: liquid lopinavir/ritonavir led to two-fold higher virologic failure rates or 15-fold greater costs than in the base-case, or second-line ART following first-line lopinavir/ritonavir was very ineffective.Conclusions:On the basis of P1060 data, first-line lopinavir/ritonavir leads to longer life expectancy and is cost-saving or very cost-effective compared to first-line nevirapine. This supports WHO guidelines, but increasing access to pediatric ART is critical regardless of the regimen used.

TI Perceived barriers in the use of ultrasound in developing countries
SO CRITICAL ULTRASOUND JOURNAL
LA English
DT Article
DE Ultrasound; Global health; Public health
ID ULTRASONOGRAPHY
AB Background: Access to ultrasound has increased significantly in resource-limited settings, including the developing world; however, there remains a lack of sonography education and ultrasound-trained physician support in developing countries. To further investigate this potential knowledge gap, our primary objective was to assess perceived barriers to ultrasound use in resource-limited settings by surveying care providers who practice in low-and middle-income settings.
Methods: A 25-question online survey was made available to health care providers who work with an ultrasound machine in low-and middle-income countries (LMICs), including doctors, nurses, technicians, and clinical officers. This was a convenience sample obtained from list-serves of ultrasound and radiologic societies. The survey was analyzed, and descriptive results were obtained.
Results: One hundred and thirty-eight respondents representing 44 LMICs including countries from the continents of Africa, South America, and Asia completed the survey, with a response rate of 9.6 %. Ninety-one percent of the respondents were doctors, and 9 % were nurses or other providers. Applications for ultrasound were diverse, including obstetrics (75 %), DVT evaluation (51 %), abscess evaluation (54 %), cardiac evaluation (64 %), inferior vena cava (IVC) assessment (49 %), Focused Assessment Sonography for Trauma (FAST) exam (64 %), biliary tree assessment (54 %), and other applications. The respondents identified the following barriers to use of ultrasound: lack of training (60 %), lack of equipment (45 %), ultrasound machine malfunction (37 %), and lack of ultrasound maintenance capability (47 %). Seventy-four percent of the respondents wished to have further training in ultrasound, and 82 % were open to receiving distance learning or telesonography training. Subjects used communication tools including Skype, Dropbox, emailed photos, and picture archiving and communication system (PACS) as ways to communicate and receive feedback on ultrasound images.
Conclusions: Health care providers in the developing world identify lack of training as a primary barrier to regular use of ultrasound in their practice. While equipment requirements including maintenance and cost of machines are also important factors, future research is warranted on best practices for training methods, including telesonography and distance learning to enhance ultrasound use in low-resource settings.

FEBRILE ILLNESS; TROPICAL DISEASES
AB Invasive Salmonellosis caused by Salmonella enterica serotype Typhi or Paratyphi A, B, C, or invasive non-typhoidal Salmonella serotypes, is an immensely important disease cluster for which reliable, rapid diagnostic tests are not available. Blood culture remains the gold standard but is insensitive, slow, and resource-intensive. Existing molecular diagnostics have poor sensitivity due to the low organism burden in bodily fluids. Commercially available serologic tests for typhoidal Salmonella have had limited sensitivity and specificity. In high burden, resource-limited settings, reliance on clinical diagnosis or inaccurate tests often results infrequent, unnecessary treatment, which contributes selective pressure for the emergence of antimicrobial resistance. This practice also results in inadequate therapy for other etiologies of acute febrile illnesses, including leptospirosis and rickettsial infections. A number of novel serologic, molecular, transcriptomic and metabolomic approaches to diagnostics are under development. Target product profiles that outline specific needs may focus development and investment, and establish benchmarks for accuracy, cost, speed, and portability of new diagnostics. Of note, a critical barrier to diagnostic assay rollout will be the low cost and low perceived harm of empiric therapy on behalf of providers and patients, which leaves few perceived incentives to utilize diagnostics. Approaches that align incentives with societal goals of limiting inappropriate antimicrobial use, such as subsidizing diagnostics, may be essential for stimulating development and uptake of such assays in resource-limited settings. New diagnostics for invasive Salmonellosis should be developed and deployed alongside diagnostics for alternative etiologies of acute febrile illnesses to improve targeted use of antibiotics.

AB Ginseng extract has been shown to possess certain anti-virus, anti-tumor and immune-activating effects. However, the immunostimulatory effect of ginseng berry extract (GB) has been less well characterized. In this study, we investigated the effect of GB on the activation of mouse dendritic cells (DCs) in vitro and in vivo. GB treatment induced up-regulation of co-stimulatory molecules in bone marrow-derived DCs (BMDCs). Interestingly, GB induced a higher degree of co-stimulatory molecule up-regulation than ginseng root extract (GR) at the same concentrations. Moreover, in vivo administration of GB promoted up-regulation of CD86, MHC class I and MHC class II and production of IL-6, IL-12 and TNF-alpha in spleen DCs. GB also promoted the generation of Th1 and Tc1 cells. Furthermore, Toll like receptor 4 (TLR4) and myeloid differentiation primary response 88 (MyD88) signaling pathway were essential for DC activation induced by GB. In addition, GB strongly prompted the proliferation of ovalbumin (OVA)-specific CD4 and CD8 T cells. Finally, GB induced DC activation in tumor-bearing mice and the combination of OVA and GB treatment inhibited B16-OVA tumor cell growth in C57BL/6 mice. These results demonstrate that GB is a novel tumor therapeutic vaccine adjuvant by promoting DC and T cell activation.

UBIQUITINATION; ACTIVATION; LEUKEMIA; CANCER; CELLS
AB The development of effective pharmacological inhibitors of multidomain scaffold proteins, notably transcription factors, is a particularly challenging problem. In part, this is because many small-molecule antagonists disrupt the activity of only one domain in the target protein. We devised a chemical strategy that promotes ligand-dependent target protein degradation using as an example the transcriptional coactivator BRD4, a protein critical for cancer cell growth and survival. We appended a competitive antagonist of BET bromodomains to a phthalimide moiety to hijack the cereblon E3 ubiquitin ligase complex. The resultant compound, dBET1, induced highly selective cereblon-dependent BET protein degradation in vitro and in vivo and delayed leukemia progression in mice. A second series of probes resulted in selective degradation of the cytosolic protein FKBP12. This chemical strategy for controlling target protein stability may have implications for therapeutically targeting previously intractable proteins.

TI The transcription factor NR4A1 is essential for the development of a
novel macrophage subset in the thymus
SO SCIENTIFIC REPORTS

AB Tissue macrophages function to maintain homeostasis and regulate immune responses. While tissue macrophages derive from one of a small number of progenitor programs, the transcriptional requirements for site-specific macrophage subset development are more complex. We have identified a new tissue macrophage subset in the thymus and have discovered that its development is dependent on transcription factor NR4A1. Functionally, we find that NR4A1-dependent macrophages are critically important for clearance of apoptotic thymocytes. These macrophages are largely reduced or absent in mice lacking NR4A1, and Nr4a1-deficient mice have impaired thymocyte engulfment and clearance. Thus, NR4A1 functions as a master transcription factor for the development of this novel thymus-specific macrophage subset.

AB It has been suggested that the evolution of vertebrate opioid receptors (ORs) follow a vector of increased functionality. Here, we test this idea by comparing human and frog ORs. Interestingly, some of the most potent opioid peptides known have been isolated from amphibian skin secretions. Here we show that such peptides (dermorphin and deltorphin) are highly potent in the human receptors and inactive in frog ORs. The molecular basis for the insensitivity of the frog ORs to these peptides was studied using chimeras and molecular modeling. The insensitivity of the delta OR (DOR) to deltorphin was due to variation of a single amino acid, Trp7.35, which is a leucine in mammalian DORs. Notably, Trp7.35 is completely conserved in all known DOR sequences from lamprey, fish, and amphibians. The deltorphin-insensitive phenotype was verified in fish. Our results provide a molecular explanation for the species selectivity of skin-derived opioid peptides.

AB Mice reconstituted with a human immune system provide a tractable in vivo model to assess human immune cell function. To date, reconstitution of murine strains with human hematopoietic stem cells (HSCs) from patients with monogenic immune disorders have not been reported. One obstacle precluding the development of immune-disease specific "humanized" mice is that optimal adaptive immune responses in current strains have required implantation of autologous human thymic tissue. To address this issue, we developed a mouse strain that lacks murine major histocompatibility complex class II (MHC II) and instead expresses human leukocyte antigen DR1 (HLA-DR1). These mice displayed improved adaptive immune responses when reconstituted with human HSCs including enhanced T-cell reconstitution, delayed-type hypersensitivity responses, and class-switch recombination. Following immune reconstitution of this novel strain with HSCs from a patient with immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome, associated with aberrant FOXP3 function, mice developed a lethal inflammatory disorder with multiorgan involvement and autoantibody production mimicking the pathology seen in affected humans. This humanized mouse model permits in vivo evaluation of immune responses associated with genetically altered HSCs, including primary immunodeficiencies, and should facilitate the study of human immune pathobiology and the development of targeted therapeutics.

AB Lead (Pb) exposure in infants and children remains an international health concern. Blood lead (PbB) levels of a cohort of 130 Ecuadorian infants and young children aged 0.33 to 5.8 yr were compared to values reported for similar age groups in Africa, Asia, Europe, Latin America, and the United States. The mean PbB level for the total group of 130 Ecuadorian infants and young children in this study was 29.4 g/dl (SD: 24.3; range: 3.0-128.2; median: 21.7; geometric mean: 20.7 g/dl). The mean PbB level for the 0-2 yr age group (infants) was 33.6 g/dl (SD: 28.9; median: 22.0; range: 3.9-119.7; geometric mean: 23.6 g/dl), while the average PbB level for the 3-5 yr age group (young children) was 27.9 g/dl (SD: 22.5: median: 22; range: 3-128.2; geometric mean: 19.8 g/dl). The difference between the mean PbB levels for the infants and young children was not statistically significant. The average PbB level of 32.6 g/dl for males was not statistically different from the mean PbB level of 26.3 g/dl for females. The PbB levels observed in Ecuadorian infants and young children in this investigation were elevated above the World Health Organization (WHO) level of concern of 10 g/dl and Centers for Disease Control and Prevention (CDC) current reference value of 5 g/dl. Values were comparable to concentrations found in Pakistan, where occupational use of Pb is prevalent. These findings further indicate that infants and young children exposed to Pb from Pb glazing of ceramics in Andean Ecuadorian villages exhibit greater potential metal-mediated poisoning than children of similar ages in Asia, Europe, other Latin American countries, and the United States.

AB Background
The HIV care continuum (diagnosis, linkage to care, retention in care, receipt of antiretroviral therapy (ART), viral suppression) has been used to identify opportunities for improving the delivery of HIV care. Continuum steps are typically calculated in a conditional manner, with the number of persons completing the prior step serving as the base population for the next step. This approach may underestimate the prevalence of viral suppression by excluding patients who are suppressed but do not meet standard definitions of retention in care. Understanding how retention in care and viral suppression interact and change over time may improve our ability to intervene on these steps in the continuum.
Methods
We followed 17,140 patients at 11 U.S. HIV clinics between 2010-2012. For each calendar year, patients were classified into one of five categories: (1) retained/suppressed, (2) retained/not-suppressed, (3) not-retained/suppressed, (4) not-retained/not-suppressed, and (5) lost to follow-up (for calendar years 2011 and 2012 only). Retained individuals were those completing >= 2 HIV medical visits separated by >= 90 days in the year. Persons not retained completed >= 1 HIV medical visit during the year, but did not meet the retention definition. Persons lost to follow-up had no HIV medical visits in the year. HIV viral suppression was defined as HIV-1 RNA <= 200 copies/mL at the last measure in the year. Multinomial logistic regression was used to determine the probability of patients' transitioning between retention/suppression categories from 2010 to 2011 and 2010 to 2012, adjusting for age, sex, race/ethnicity, HIV risk factor, insurance status, CD4 count, and use of ART.
Results
Overall, 65.8% of patients were retained/suppressed, 17.4% retained/not-suppressed, 10.0% not-retained/suppressed, and 6.8% not-retained/not-suppressed in 2010. 59.5% of patients maintained the same status in 2011 (kappa=0.458) and 53.3% maintained the same status in 2012 (kappa=0.437).
Conclusions
Not counting patients not-retained/suppressed as virally suppressed, as is commonly done in the HIV care continuum, underestimated the proportion suppressed by 13%. Applying the care continuum in a longitudinal manner will enhance its utility.

ID ENDOPLASMIC-RETICULUM STRESS; TRANSCRIPTION FACTOR; XBP1; IMMUNITY
AB XBP1 is part of the ER stress response, and when activated in cancer cells, it fosters tumor growth. In this issue of Cell, Cubillos-Ruiz et al. demonstrate that XBP1 in tumor-infiltrating dendritic cells blunts anti-tumor immunity. These findings further imply XBP1 as a relevant target for cancer therapy.

INJURY
AB Hematopoietic stem cells (HSCs) reside in hypoxic niches within bone marrow and cord blood. Yet, essentially all HSC studies have been performed with cells isolated and processed in non-physiologic ambient air. By collecting and manipulating bone marrow and cord blood in native conditions of hypoxia, we demonstrate that brief exposure to ambient oxygen decreases recovery of long-term repopulating HSCs and increases progenitor cells, a phenomenon we term extraphysiologic oxygen shock/stress (EPHOSS). Thus, true numbers of HSCs in the bone marrow and cord blood are routinely underestimated. We linked ROS production and induction of the mitochondrial permeability transition pore (MPTP) via cyclophilin D and p53 as mechanisms of EPHOSS. The MPTP inhibitor cyclosporin A protects mouse bone marrow and human cord blood HSCs from EPHOSS during collection in air, resulting in increased recovery of transplantable HSCs. Mitigating EPHOSS during cell collection and processing by pharmacological means may be clinically advantageous for transplantation.

TI An organic jelly made fractal logic gate with an infinite truth table
SO SCIENTIFIC REPORTS
LA English
DT Article
ID CHAOS; COMPUTATION; TIME
AB Widely varying logic gates invented over a century are all finite. As data deluge problem looms large on the information processing and communication industry, the thrust to explore radical concepts is increasing rapidly. Here, we design and synthesis a molecule, wherein, the input energy transmits in a cycle inside the molecular system, just like an oscillator, then, we use the molecule to make a jelly that acts as chain of oscillators with a fractal like resonance band. Hence, with the increasing detection resolution, in the vacant space between two energy levels of a given resonance band, a new band appears, due to fractal nature, generation of newer energy levels never stops. This is natural property of a linear chain oscillator. As we correlate each energy level of the resonance band of organic jelly, as a function of pH and density of the jelly, we realize a logic gate, whose truth table is finite, but if we zoom any small part, a new truth table appears. In principle, zooming of truth table would continue forever. Thus, we invent a new class of infinite logic gate for the first time.

TI Ezetimibe Added to Statin Therapy after Acute Coronary Syndromes
SO NEW ENGLAND JOURNAL OF MEDICINE

PLACEBO-CONTROLLED TRIAL; CLINICAL-TRIALS; HEART-DISEASE; CARDIOVASCULAR
OUTCOMES; MYOCARDIAL-INFARCTION; HYPERTENSIVE PATIENTS; PRIMARY
PREVENTION; LOWERING TREATMENT
AB BACKGROUND
Statin therapy reduces low-density lipoprotein (LDL) cholesterol levels and the risk of cardiovascular events, but whether the addition of ezetimibe, a nonstatin drug that reduces intestinal cholesterol absorption, can reduce the rate of cardiovascular events further is not known.
METHODS
We conducted a double-blind, randomized trial involving 18,144 patients who had been hospitalized for an acute coronary syndrome within the preceding 10 days and had LDL cholesterol levels of 50 to 100 mg per deciliter (1.3 to 2.6 mmol per liter) if they were receiving lipid-lowering therapy or 50 to 125 mg per deciliter (1.3 to 3.2 mmol per liter) if they were not receiving lipid-lowering therapy. The combination of simvastatin (40 mg) and ezetimibe (10 mg) (simvastatin-ezetimibe) was compared with simvastatin (40 mg) and placebo (simvastatin monotherapy). The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, unstable angina requiring rehospitalization, coronary revascularization (>= 30 days after randomization), or nonfatal stroke. The median follow-up was 6 years.
RESULTS
The median time-weighted average LDL cholesterol level during the study was 53.7 mg per deciliter (1.4 mmol per liter) in the simvastatin-ezetimibe group, as compared with 69.5 mg per deciliter (1.8 mmol per liter) in the simvastatin-monotherapy group (P< 0.001). The Kaplan-Meier event rate for the primary end point at 7 years was 32.7% in the simvastatin-ezetimibe group, as compared with 34.7% in the simvastatin-monotherapy group (absolute risk difference, 2.0 percentage points; hazard ratio, 0.936; 95% confidence interval, 0.89 to 0.99; P = 0.016). Rates of pre-specified muscle, gallbladder, and hepatic adverse effects and cancer were similar in the two groups.
CONCLUSIONS
When added to statin therapy, ezetimibe resulted in incremental lowering of LDL cholesterol levels and improved cardiovascular outcomes. Moreover, lowering LDL cholesterol to levels below previous targets provided additional benefit.

IMMUNODEFICIENCY; INBORN-ERRORS; IMMUNITY; MUTATIONS; LYMPHOCYTE;
TOLERANCE; DEDICATOR
AB BACKGROUND
Combined immunodeficiencies are marked by inborn errors of T-cell immunity in which the T cells that are present are quantitatively or functionally deficient. Impaired humoral immunity is also common. Patients have severe infections, auto-immunity, or both. The specific molecular, cellular, and clinical features of many types of combined immunodeficiencies remain unknown.
METHODS
We performed genetic and cellular immunologic studies involving five unrelated children with early-onset invasive bacterial and viral infections, lymphopenia, and defective T-cell, B-cell, and natural killer (NK)-cell responses. Two patients died early in childhood; after allogeneic hematopoietic stem-cell transplantation, the other three had normalization of T-cell function and clinical improvement.
RESULTS We identified biallelic mutations in the dedicator of cytokinesis 2 gene (DOCK2) in these five patients. RAC1 activation was impaired in the T cells. Chemokine-induced migration and actin polymerization were defective in the T cells, B cells, and NK cells. NK-cell degranulation was also affected. Interferon-a and interferon-lambda production by peripheral-blood mononuclear cells was diminished after viral infection. Moreover, in DOCK2-deficient fibroblasts, viral replication was increased and virus-induced cell death was enhanced; these conditions were normalized by treatment with interferon alfa-2b or after expression of wild-type DOCK2.
CONCLUSIONS
Autosomal recessive DOCK2 deficiency is a new mendelian disorder with pleiotropic defects of hematopoietic and nonhematopoietic immunity. Children with clinical features of combined immunodeficiencies, especially with early-onset, invasive infections, may have this condition.

AB Normal hearing requires proper differentiation of afferent ribbon synapses between inner hair cells (IHCs) and spiral ganglion neurons (SGNs) that carry acoustic information to the brain. Within individual IHCs, presynaptic ribbons show a size gradient with larger ribbons on the modiolar face and smaller ribbons on the pillar face. This structural gradient is associated with a gradient of spontaneous rates and threshold sensitivity, which is essential for a wide dynamic range of hearing. Despite their importance for hearing, mechanisms that direct ribbon differentiation are poorly defined. We recently identified adenomatous polyposis coli protein (APC) as a key regulator of interneuronal synapse maturation. Here, we show that APC is required for ribbon size heterogeneity and normal cochlear function. Compared with wild-type littermates, APC conditional knock-out (cKO) mice exhibit decreased auditory brainstem responses. The IHC ribbon size gradient is also perturbed. Whereas the normal-developing IHCs display ribbon size gradients before hearing onset, ribbon sizes are aberrant in APC cKOs from neonatal ages on. Reporter expression studies show that the CaMKII-Cre used to delete the floxed APC gene is present in efferent olivocochlear (OC) neurons, not IHCs or SGNs. APC loss led to increased volumes and numbers of OC inhibitory dopaminergic boutons on neonatal SGN fibers. Our findings identify APC in efferent OC neurons as essential for regulating ribbon heterogeneity, dopaminergic terminal differentiation, and cochlear sensitivity. ThisAPCeffect on auditory epithelial cell synapses resembles interneuronal and nerve-muscle synapses, thereby defining a global role for APC in synaptic maturation in diverse cell types.

AB The aim of the present study is to explore obsessive-compulsive disorder (OCD)-related abnormalities in white matter connectivity in OCD for a core region associated with inhibitory control [i.e. inferior frontal gyrus (IFG)]. Fifteen patients with OCD (11 men) and 15 healthy controls (nine men) underwent diffusion tensor imaging scanning to study four diffusivity indexes of white matter integrity [fractional anisotropy, mean diffusivity (MD), axial diffusivity and radial diffusivity (RD)]. The results showed that persons with OCD manifested significantly lower fractional anisotropy levels in the bilateral IFG as well as its parcellations in the pars opercularis, pars triangularis, and pars orbitalis. Significantly higher levels of MD, RD were evident for the OCD group in the IFG as a whole as well as in the bilateral subregions of the pars triangularis and pars opercularis (for MD and RD), the right side of the pars orbitalis (for RD), and the left side of the pars triangularis and right side pars opercularis (for axial diffusivity). Overall, the results suggest significant alterations in structural connectivity, probably associated with myelination and axonal abnormalities in the IFG of OCD patients.

AB The hormone glucagon-like peptide-1 (GLP-1) regulates appetite and food intake. GLP-1 receptor (GLP-1R) activation also attenuates the reinforcing properties of alcohol in rodents. The present translational study is based on four human genetic association studies and one preclinical study providing data that support the hypothesis that GLP-1R may have a role in the pathophysiology of alcohol use disorder (AUD). Case-control analysis (N = 908) was performed on a sample of individuals enrolled in the National Institute on Alcohol Abuse and Alcoholism (NIAAA) intramural research program. The Study of Addiction: Genetics and Environment (SAGE) sample (N = 3803) was used for confirmation purposes. Post hoc analyses were carried out on data from a human laboratory study of intravenous alcohol self-administration (IV-ASA; N = 81) in social drinkers and from a functional magnetic resonance imaging study in alcohol-dependent individuals (N = 22) subjected to a Monetary Incentive Delay task. In the preclinical study, a GLP-1R agonist was evaluated in a mouse model of alcohol dependence to demonstrate the role of GLP-1R for alcohol consumption. The previously reported functional allele 168Ser (rs6923761) was nominally associated with AUD (P = 0.004) in the NIAAA sample, which was partially replicated in males of the SAGE sample (P = 0.033). The 168Ser/Ser genotype was further associated with increased alcohol administration and breath alcohol measures in the IV-ASA experiment and with higher BOLD response in the right globus pallidus when receiving notification of outcome for high monetary reward. Finally, GLP-1R agonism significantly reduced alcohol consumption in a mouse model of alcohol dependence. These convergent findings suggest that the GLP-1R may be an attractive target for personalized pharmacotherapy treatment of AUD.

AB The pathophysiological response to a severe burn injury involves a robust increase in circulating inflammatory/endocrine factors and a hypermetabolic state, both of which contribute to prolonged skeletal muscle atrophy. In order to characterize the role of circulating factors in muscle atrophy following a burn injury, human skeletal muscle satellite cells were grown in culture and differentiated to myoblasts/myotubes in media containing serum from burn patients or healthy, age, and sex-matched controls. While incubation in burn serum did not affect NF kappa B signaling, cells incubated in burn serum displayed a transient increase in STAT3 phosphorlyation (Tyr705) after 48 h of treatment with burn serum (approximate to + 70%; P < 0.01), with these levels returning to normal by 96 h. Muscle cells differentiated in burn serum displayed reduced myogenic fusion signaling (phospho-STAT6 (Tyr641), approximate to-75% ADAM12, approximate to-20% both P < 0.01), and reduced levels of myogenin (approximate to-75% P < 0.05). Concomitantly, myotubes differentiated in burn serum demonstrated impaired myogenesis (assessed by number of nuclei/myotube). Incubation in burn serum for 96 h did not increase proteolytic signaling (assessed via caspase-3 and ubiquitin levels), but reduced anabolic signaling [p-p70S6k (Ser421/Thr424), -30%; p-rpS6 (Ser240/244), approximate to -50%] and impaired protein synthesis (-24%) (P < 0.05). This resulted in a loss of total protein content (-18%) and reduced cell size (-33%) (P < 0.05). Overall, incubation of human muscle cells in serum from burn patients results in impaired myogenesis and reduced myotube size, indicating that circulating factors may play a significant role in muscle loss and impaired muscle recovery following burn injury.

TI Tag and Capture Flow Hydrogen Exchange Mass Spectrometry with a

AB Analysis of complex mixtures of proteins by hydrogen exchange (HX) mass spectrometry (MS) is limited by one's ability to resolve the protein(s) of interest from the proteins that are not of interest. One strategy for overcoming this problem is to tag the target protein(s) to allow for rapid removal from the mixture for subsequent analysis. Here we illustrate a new solution involving fluorous conjugation of a retrievable probe. The appended fluorous tag allows for facile immobilization on a fluorous surface. When a target protein is passed over the immobilized probe molecule, it can be efficiently captured and then exposed to a flowing stream of deuterated buffer for hydrogen exchange. The utility of this method is illustrated for a model system of the Elongin BC protein complex bound to a peptide from HIV Vif. Efficient capture is demonstrated, and deuteration when immobilized was identical to deuteration in conventional solution-phase hydrogen exchange MS. Protein captured from a crude bacterial cell lysate could also be deuterated without the need for separate purification steps before HX MS. The advantages and disadvantages of the method are discussed in light of miniaturization and automation.

AB Mechanical forces transduced to cells through the extracellular matrix are critical regulators of tissue development, growth, and homeostasis, and can play important roles in directing stem cell differentiation. In addition to force-sensing mechanisms that reside at the cell surface, there is growing evidence that forces transmitted through the cytoskeleton and to the nuclear envelope are important for mechanosensing, including activation of the Yes-associated protein (YAP)/transcriptional coactivator with PDZ-binding motif (TAZ) pathway. Moreover, nuclear shape, mechanics, and deformability change with differentiation state and have been likewise implicated in force sensing and differentiation. However, the significance of force transfer to the nucleus through the mechanosensing cytoskeletal machinery in the regulation of mesenchymal stem cell mechanobiologic response remains unclear. Here we report that actomyosin-generated cytoskeletal tension regulates nuclear shape and force transmission through the cytoskeleton and demonstrate the differential short- and long-term response of mesenchymal stem cells to dynamic tensile loading based on the contractility state, the patency of the actin cytoskeleton, and the connections it makes with the nucleus. Specifically, we show that while some mechanoactive signaling pathways (e.g., ERK signaling) can be activated in the absence of nuclear strain transfer, cytoskeletal strain transfer to the nucleus is essential for activation of the YAP/TAZ pathway with stretch.

AB Basal-like and luminal breast tumors have distinct clinical behavior and molecular profiles, yet the underlying mechanisms are poorly defined. To interrogate processes that determine these distinct phenotypes and their inheritance pattern, we generated somatic cell fusions and performed integrated genetic and epigenetic (DNA methylation and chromatin) profiling. We found that the basal-like trait is generally dominant and is largely defined by epigenetic repression of luminal transcription factors. Definition of super-enhancers highlighted a core program common in luminal cells but a high degree of heterogeneity in basal-like breast cancers that correlates with clinical outcome. We also found that protein extracts of basal-like cells are sufficient to induce a luminal-to-basal phenotypic switch, implying a trigger of basal-like autoregulatory circuits. We determined that KDM6A might be required for luminal-basal fusions, and we identified EN1, TBX18, and TCF4 as candidate transcriptional regulators of the luminal-to-basal switch. Our findings highlight the remarkable epigenetic plasticity of breast cancer cells.

AB A highly glycosylated, trimeric envelope glycoprotein (Env) mediates HIV-1 cell entry. The high density and heterogeneity of the glycans shield Env from recognition by the immune system, but paradoxically, many potent broadly neutralizing antibodies (bNAbs) recognize epitopes involving this glycan shield. To better understand Env glycosylation and its role in bNAb recognition, we characterized a soluble, cleaved recombinant trimer (BG505 SOSIP.664) that is a close structural and antigenic mimic of native Env. Large, unprocessed oligomannose-type structures (Man(8-9)GlcNAc(2)) are notably prevalent on the gp120 components of the trimer, irrespective of the mammalian cell expression system or the bNAb used for affinity purification. In contrast, gp41 subunits carry more highly processed glycans. The glycans on uncleaved, non-native oligomeric gp140 proteins are also highly processed. A homogeneous, oligomannose-dominated glycan profile is therefore a hallmark of a native Env conformation and a potential Achilles' heel that can be exploited for bNAb recognition and vaccine design.

AB The repair of DNA double-strand breaks (DSBs) requires open, flexible chromatin domains. The NuA4-Tip60 complex creates these flexible chromatin structures by exchanging histone H2A.Z onto nucleosomes and promoting acetylation of histone H4. Here, we demonstrate that the accumulation of H2A.Z on nucleosomes at DSBs is transient, and that rapid eviction of H2A.Z is required for DSB repair. Anp32e, an H2A.Z chaperone that interacts with the C-terminal docking domain of H2A.Z, is rapidly recruited to DSBs. Anp32e functions to remove H2A.Z from nucleosomes, so that H2A.Z levels return to basal within 10 min of DNA damage. Further, H2A.Z removal by Anp32e disrupts inhibitory interactions between the histone H4 tail and the nucleosome surface, facilitating increased acetylation of histone H4 following DNA damage. When H2A.Z removal by Anp32e is blocked, nucleosomes at DSBs retain elevated levels of H2A.Z, and assume a more stable, hypoacetylated conformation. Further, loss of Anp32e leads to increased CtIP-dependent end resection, accumulation of single-stranded DNA, and an increase in repair by the alternative non-homologous end joining pathway. Exchange of H2A.Z onto the chromatin and subsequent rapid removal by Anp32e are therefore critical for creating open, acetylated nucleosome structures and for controlling end resection by CtIP. Dynamic modulation of H2A.Z exchange and removal by Anp32e reveals the importance of the nucleosome surface and nucleosome dynamics in processing the damaged chromatin template during DSB repair.

AB Cell volume homeostasis is vital for the maintenance of optimal protein density and cellular function. Numerous mammalian cell types are routinely exposed to acute hypertonic challenge and shrink. Molecular crowding modifies biochemical reaction rates and decreases macromolecule diffusion. Cell volume is restored rapidly by ion influx but at the expense of elevated intracellular sodium and chloride levels that persist long after challenge. Although recent studies have highlighted the role of molecular crowding on the effects of hypertonicity, the effects of ionic imbalance on cellular trafficking dynamics in living cells are largely unexplored. By tracking distinct fluorescently labeled endosome/vesicle populations by live-cell imaging, we show that vesicle motility is reduced dramatically in a variety of cell types at the onset of hypertonic challenge. Live-cell imaging of actin and tubulin revealed similar arrested microfilament motility upon challenge. Vesicle motility recovered long after cell volume, a process that required functional regulatory volume increase and was accelerated by a return of extracellular osmolality to isosmotic levels. This delay suggests that, although volume-induced molecular crowding contributes to trafficking defects, it alone cannot explain the observed effects. Using fluorescent indicators and FRET-based probes, we found that intracellular ATP abundance and mitochondrial potential were reduced by hypertonicity and recovered after longer periods of time. Similar to the effects of osmotic challenge, isovolumetric elevation of intracellular chloride concentration by ionophores transiently decreased ATP production by mitochondria and abated microfilament and vesicle motility. These data illustrate how perturbed ionic balance, in addition to molecular crowding, affects membrane trafficking.

AB Osteosarcoma is the most common primary bone malignancy in children and adolescents. Herein, we investigated the role of cluster of differentiation 44 (CD44), a cell-surface glycoprotein involved in cell-cell interactions, cell adhesion, and migration in osteosarcoma. We constructed a human osteosarcoma tissue microarray with 114 patient tumor specimens, including tumor tissues from primary, metastatic, and recurrent stages, and determined the expression of CD44 by immunohistochemistry. Results showed that CD44 was overexpressed in metastatic and recurrent osteosarcoma as compared with primary tumors. Higher expression of CD44 was found in both patients with shorter survival and patients who exhibited unfavorable response to chemotherapy before surgical resection. Additionally, the 3'-untranslated region of CD44 mRNA was the direct target of microRNA-199a-3p (miR-199a-3p). Overexpression of miR-199a-3p significantly inhibited CD44 expression in osteosarcoma cells. miR-199a-3p is one of the most dramatically decreased miRs in osteosarcoma cells and tumor tissues as compared with normal osteoblast cells. Transfection of miR-199a-3p significantly increased the drug sensitivity through down-regulation of CD44 in osteosarcoma cells. Taken together, these results suggest that the CD44-miR-199a-3p axis plays an important role in the development of metastasis, recurrence, and drug resistance of osteosarcoma. Developing strategies to target CD44 may improve the clinical outcome of osteosarcoma.

AB Tissue effector cells of the monocyte lineage can differentiate into different cell types with specific cell function depending on their environment. The phenotype, developmental requirements, and functional mechanisms of immune protective macrophages that mediate the induction of transplantation tolerance remain elusive. Here, we demonstrate that costimulatory blockade favored accumulation of DC-SIGN-expressing macrophages that inhibited CD8(+) T cell immunity and promoted CD4(+)Foxp3(+) Treg cell expansion in numbers. Mechanistically, that simultaneous DC-SIGN engagement by fucosylated ligands and TLR4 signaling was required for production of immunoregulatory IL-10 associated with prolonged allograft survival. Deletion of DC-SIGN-expressing macrophages in vivo, interfering with their CSF1-dependent development, or preventing the DC-SIGN signaling pathway abrogated tolerance. Together, the results provide new insights into the tolerogenic effects of costimulatory blockade and identify DC-SIGN(+) suppressive macrophages as crucial mediators of immunological tolerance with the concomitant therapeutic implications in the clinic.

AB PLK (Polo-like kinase) inhibitors, such as BI-2536, have been reported to suppress IFNB (encoding IFN beta, interferon beta) gene transcription induced by ligands that activate TLR3 (Toll-like receptor 3) and TLR4. In the present study, we found that BI-2536 is likely to exert this effect by preventing the interaction of the transcription factors IRF3 (interferon-regulatory factor 3) and c-Jun with the IFNB promoter, but without affecting the TBK1 {TANK [ TRAF (tumour-necrosis-factor-receptor-associated factor)-associated nuclear factor kappa B activator]-binding kinase 1}-catalysed phosphorylation of IRF3 at Ser(396), the dimerization and nuclear translocation of IRF3 or the phosphorylation of c-Jun andATF2 (activating transcription factor 2). Although BI-2536 inhibits few other kinases tested, it interacts with BET (bromodomain and extra-terminal) family members and displaces them from acetylated lysine residues on histones. We found that BET inhibitors that do not inhibit PLKs phenocopied the effect of BI-2536 on IFNB gene transcription. Similarly, BET inhibitors blocked the interaction of IRF5 with the IFNB promoter and the secretion of IFN beta induced by TLR7 or TLR9 ligands in the human plasmacytoid dendritic cell line GEN2.2, but without affecting the nuclear translocation of IRF5. We found that the BET family member BRD4 (bromodomain-containing protein 4) was associated with the IFNB promoter and that this interaction was enhanced by TLR3-or TLR4-ligation and prevented by BI2536 and other BET inhibitors. Our results establish that BET family members are essential for TLR-stimulated IFNB gene transcription by permitting transcription factors to interact with the IFNB promoter. They also show that the interaction of the IFNB promoter with BRD4 is regulated by TLR ligation and that BI-2536 is likely to suppress IFNB gene transcription by targeting BET family members.

AB Background. Weight gain after antiretroviral therapy (ART) initiation is common, but its implication for mortality is unknown. We evaluated weight change in the first year after ART initiation and its association with subsequent mortality.
Methods. Human immunodeficiency virus-infected patients from the Veterans Aging Cohort Study (VACS) who initiated ART between 2000 and 2008, with weight recorded at baseline and 1 year later, were followed another 5 years for mortality. Baseline body mass index (BMI) was classified as underweight (<18.5 kg/m(2)), normal (18.5-24.9 kg/m(2)), overweight (25-29.9 kg/m(2)), and obese (>= 30 kg/m(2)). We used multivariable Cox models to assess mortality risk with adjustment for disease severity using the VACS Index.
Results. The sample consisted of 4184 men and 127 women with a mean age of 47.9 +/- 10.0 years. After 1 year of ART, median weight change was 5.9 pounds (2.7 kg) (interquartile range, -2.9 to 17.0 pounds, -1.3 to 7.7 kg). Weight gain after ART initiation was associated with lower mortality among underweight and normal-weight patients. A minimum threshold of 10- to 19.9-pound (4.5 to 9.0 kg) weight gain was beneficial for normal-weight patients (hazard ratio, 0.56; 95% confidence interval, .41-.78), but there was no clear benefit to weight gain for overweight/obese patients. Baseline weight, CD4 cell count status, and hemoglobin level were strongly associated with weight gain. Risk for weight gain was higher among those with greater disease severity, regardless of weight at initiation.
Conclusions. The survival benefits of weight gain after ART initiation are dependent on starting BMI. Weight gain after ART is associated with lower mortality for those who are not initially overweight.

AB With increasing application of targeted therapies and the development of acquired resistance, much attention is being focused on developing in vitro and in vivo patient-specific tumor models for individualized therapeutic evaluation of cancers. Circulating tumor cells provide a source of noninvasively and sequentially sampled invasive cancer cells suitable for propagation in vitro. We review the advantages and challenges associated with ex vivo culture of tumor cells circulating in the blood of patients with cancer. (C) 2015 AACR.

AB Purpose: Anaplastic lymphoma kinase (ALK) rearrangements are important therapeutic targets in non-small cell lung cancer (NSCLC) that confer sensitivity to the ALK inhibitors crizotinib and ceritinib. To determine the outcome of sequential treatment with crizotinb and ceritinib, we retrospectively evaluated a cohort of ALK-positive patients treated with both agents.
Experimental Design: We identified 73 ALK-positive NSCLC patients treated with crizotinib followed by ceritinib at four institutions. Medical records were reviewed to determine overall survival (OS) and progression-free survival (PFS) on crizotinib and ceritinib.
Results: Among 73 ALK-positive patients, the median PFS (mPFS) on crizotinib was 8.2 months [95% confidence interval (CI), 7.4-10.6]. The median interval from crizotinib discontinuation to initiation of ceritinib was 25 days (range, 1-694). The mPFS on ceritinib was 7.8 months (6.5-9.1). Among 53 patients with no interval therapies between crizotinib and ceritinib, the mPFS on ceritinib was similar at 7.8 months (5.4-9.8). The median combined PFS for sequential treatment with crizotinib and ceritinib was 17.4 months (15.5-19.4). Among 23 patients who underwent post-crizotinib/pre-ceritinib biopsies, there was no difference in PFS on ceritinib between patients with or without ALK resistance mutations (mPFS 5.8 vs. 6.5 months, respectively; P = 0.510). In the overall study population, median OS was 49.4 months (35.5-63.1).
Conclusions: Ceritinib has significant antitumor activity in ALK-positive NSCLC-even when crizotinib immediately precedes treatment with ceritinib (median combined PFS 17.0 months). Additional studies are necessary to further define the impact of specific ALK resistance mutations on duration of response to ceritinib. (C) 2015 AACR.

TI In silico phenotyping via co-training for improved phenotype prediction
from genotype
SO BIOINFORMATICS
LA English
DT Article
ID GENOME-WIDE ASSOCIATION; MIGRAINE
AB Motivation: Predicting disease phenotypes from genotypes is a key challenge in medical applications in the postgenomic era. Large training datasets of patients that have been both genotyped and phenotyped are the key requisite when aiming for high prediction accuracy. With current genotyping projects producing genetic data for hundreds of thousands of patients, large-scale phenotyping has become the bottleneck in disease phenotype prediction.
Results: Here we present an approach for imputing missing disease phenotypes given the genotype of a patient. Our approach is based on co-training, which predicts the phenotype of unlabeled patients based on a second class of information, e.g. clinical health record information. Augmenting training datasets by this type of in silico phenotyping can lead to significant improvements in prediction accuracy. We demonstrate this on a dataset of patients with two diagnostic types of migraine, termed migraine with aura and migraine without aura, from the International Headache Genetics Consortium.
Conclusions: Imputing missing disease phenotypes for patients via co-training leads to larger training datasets and improved prediction accuracy in phenotype prediction.

TI Evaluation of the i-STAT point-of-care capillary whole blood hematocrit

AB Background: Conductivity based point-of-care hematocrit with calculated hemoglobin devices serves an important role in clinical scenarios where time sensitive transfusion decisions are necessary. However, questions about the appropriateness of conductivity based assays in certain patient populations (patients on cardiopulmonary bypass and those receiving high volumes of intravenous fluids or autologous blood transfusions) have been raised. The clinical suitability of POC devices for these applications necessitates that they be accurate and that the results are interchangeable with central laboratory methods.
Methods: We performed hematocrit and hemoglobin analysis on 225 clinical samples using the i-STAT instrument, a standard reference method for hematocrit (manual spun) and other common methods on both cardiopulmonary bypass and non-cardiopulmonary bypass patients.
Results: The i-STAT hematocrit and hemoglobin showed close agreement to comparison methods with minimal bias Median test results were not clinically or statistically different between those measured on the i-STAT and those measured using the manual spun hematocrit reference method (p = 0.4085, Wilcoxon signed rank test) or the Sysmex photometric hemoglobin method (p = 0.2728, Wilcoxon signed rank test). The results on the i-STAT were statistically different from those obtained on the Sysmex for hematocrit (p < 0.0001) and the Siemens RAPIDLab co-oximeter for hemoglobin (p < 0.0001).
Conclusion: The i-STAT hematocrit and hemoglobin performs well when compared to the hematocrit reference method and other common methods for both hematocrit and hemoglobin. Some differences between non-reference methods may be observed, but these were not considered clinically significant (C) 2015 Elsevier B.V. All rights reserved.

AB Epidemiological evidence suggests that exposure to ozone increases cardiovascular morbidity. However, the specific biological mechanisms mediating ozone-associated cardiovascular effects are unknown. To determine whether short-term exposure to ambient levels of ozone causes changes in biomarkers of cardiovascular disease including heart rate variability (HRV), systemic inflammation, and coagulability, 26 subjects were exposed to 0, 100, and 200 ppb ozone in random order for 4 h with intermittent exercise. HRV was measured and blood samples were obtained immediately before (0 h), immediately after (4 h), and 20 h after (24 h) each exposure. Bronchoscopy with bronchoalveolar lavage (BAL) was performed 20 h after exposure. Regression modeling was used to examine dose-response trends between the endpoints and ozone exposure. Inhalation of ozone induced dose-dependent adverse changes in the frequency domains of HRV across exposures consistent with increased sympathetic tone [increase of (parameter estimate +/- SE) 0.4 +/- 0.2 and 0.3 +/- 0.1 in low-to high-frequency domain HRV ratio per 100 ppb increase in ozone at 4 h and 24 h, respectively (P = 0.02 and P = 0.01)] and a dosedependent increase in serum C-reactive protein (CRP) across exposures at 24 h [increase of 0.61 +/- 0.24 mg/l in CRP per 100 ppb increase in ozone (P = 0.01)]. Changes in HRV and CRP did not correlate with ozone-induced local lung inflammatory responses (BAL granulocytes, IL-6, or IL-8), but changes in HRV and CRP were associated with each other after adjustment for age and ozone level. Inhalation of ozone causes adverse systemic inflammatory and cardiac autonomic effects that may contribute to the cardiovascular mortality associated with short-term exposure.

AB Mutant p53 impacts the expression of numerous genes at the level of transcription to mediate oncogenesis. We identified vascular endothelial growth factor receptor 2 (VEGFR2), the primary functional VEGF receptor that mediates endothelial cell vascularization, as a mutant p53 transcriptional target in multiple breast cancer cell lines. Up-regulation of VEGFR2 mediates the role of mutant p53 in increasing cellular growth in two-dimensional (2D) and three-dimensional (3D) culture conditions. Mutant p53 binds near the VEGFR2 promoter transcriptional start site and plays a role in maintaining an open conformation at that location. Relatedly, mutant p53 interacts with the SWI/SNF complex, which is required for remodeling the VEGFR2 promoter. By both querying individual genes regulated by mutant p53 and performing RNA sequencing, the results indicate that >40% of all mutant p53-regulated gene expression is mediated by SWI/SNF. We surmise that mutant p53 impacts transcription of VEGFR2 as well as myriad other genes by promoter remodeling through interaction with and likely regulation of the SWI/SNF chromatin remodeling complex. Therefore, not only might mutant p53-expressing tumors be susceptible to anti VEGF therapies, impacting SWI/SNF tumor suppressor function in mutant p53 tumors may also have therapeutic potential.

AB Pericytes are embedded within basal lamina and play multiple roles in the perivascular niche in brain. Recently, oligodendrocyte precursor cells (OPCs) have also been reported to associate with cerebral endothelium. Is it possible that within this gliovascular locus, there may also exist potential spatial and functional interactions between pericytes and OPCs? Here, we demonstrated that in the perivascular region of cerebral white matter, pericytes and OPCs may attach and support each other. Immunostaining showed that pericytes and OPCs are localized in close contact with each other in mouse white matter at postnatal days 0, 60 and 240. Electron microscopic analysis confirmed that pericytes attached to OPCs via basal lamina in the perivascular region. The close proximity between these two cell types was also observed in postmortem human brains. Functional interaction between pericytes and OPCs was assessed by in vitro media transfer experiments. When OPC cultures were treated with pericyte-conditioned media, OPC number increased. Similarly, pericyte number increased when pericytes were maintained in OPC-conditioned media. Taken together, our data suggest a potential anatomical and functional interaction between pericytes and OPCs in cerebral white matter. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB PICALM (Phosphatidyl Inositol Clathrin Assembly Lymphoid Myeloid protein) is a ubiquitously expressed protein that plays a role in clathrin-mediated endocytosis. PICALM also affects the internalization and trafficking of SNAREs and modulates macroautophagy. Chromosomal translocations that result in the fusion of PICALM to heterologous proteins cause leukemias, and genome-wide association studies have linked PICALM Single Nucleotide Polymorphisms (SNPs) to Alzheimer's disease. To obtain insight into the biological role of PICALM, we performed gene expression studies of PICALM-deficient and PICALM-expressing cells. Pathway analysis demonstrated that PICALM expression influences the expression of genes that encode proteins involved in cholesterol biosynthesis and lipoprotein uptake. Gas Chromatography-Mass Spectrometry (GC-MS) studies indicated that loss of PICALM increases cellular cholesterol pool size. Isotopic labeling studies revealed that loss of PICALM alters increased net scavenging of cholesterol. Flow cytometry analyses confirmed that internalization of the LDL receptor is enhanced in PICALM-deficient cells as a result of higher levels of LDLR expression. These findings suggest that PICALM is required for cellular cholesterol homeostasis and point to a novel mechanism by which PICALM alterations may contribute to disease.

AB Prior efforts to identify a blood biomarker of brain injury have relied almost exclusively on proteins; however their low levels at early time points and poor correlation with injury severity have been limiting. Lipids, on the other hand, are the most abundant molecules in the brain and readily cross the blood-brain barrier. We previously showed that certain sphingolipid (SL) species are highly specific to the brain. Here we examined the feasibility of using SLs as biomarkers for acute brain injury. A rat model of traumatic brain injury (TBI) and a mouse model of stroke were used to identify candidate SL species though our mass-spectrometry based lipid profiling approach. Plasma samples collected after TBI in the rat showed large increases in many circulating SLs following injury, and larger lesions produced proportionately larger increases. Plasma samples collected 24 hours after stroke in mice similarly revealed a large increase in many SLs. We constructed an SL score (sum of the two SL species showing the largest relative increases in the mouse stroke model) and then evaluated the diagnostic value of this score on a small sample of patients (n = 14) who presented with acute stroke symptoms. Patients with true stroke had significantly higher SL scores than patients found to have non-stroke causes of their symptoms. The SL score correlated with the volume of ischemic brain tissue. These results demonstrate the feasibility of using lipid biomarkers to diagnose brain injury. Future studies will be needed to further characterize the diagnostic utility of this approach and to transition to an assay method applicable to clinical settings.

AB Lung cancer outcomes remain poor despite the identification of several potential therapeutic targets. The EPHB4 receptor tyrosine kinase (RTK) has recently emerged as an oncogenic factor in many cancers, including lung cancer. Mutations of EPHB4 in lung cancers have previously been identified, though their significance remains unknown. Here, we report the identification of novel EPHB4 mutations that lead to putative structural alterations as well as increased cellular proliferation and motility. We also conducted a bioinformatic analysis of these mutations to demonstrate that they are mutually exclusive from other common RTK variants in lung cancer, that they correspond to analogous sites of other RTKs' variations in cancers, and that they are predicted to be oncogenic based on biochemical, evolutionary, and domain-function constraints. Finally, we show that EPHB4 mutations can induce broad changes in the kinome signature of lung cancer cells. Taken together, these data illuminate the role of EPHB4 in lung cancer and further identify EPHB4 as a potentially important therapeutic target.

AB To investigate the role of secreted protein acidic and rich in cysteine (SPARC) in age-related cardiac inflammation, we studied six groups of mice: young (3-5 mo old), middle-aged (10-12 mo old), and old (18-29 mo old) C57BL/6 wild-type (WT) and SPARC-null (Null) mice (n = 7-10/group). Cardiac function and structure were determined by echocardiography. The left ventricle was used for cytokine gene array and macrophage quantification by immunohistochemistry. Macrophage infiltration increased with age in WT (n = 5-6/group, P < 0.05 for young vs. old), but not in Null. Proinflammatory markers (Ccl5, Cx3cl1, Ccr2, and Cxcr3) increased in middle-aged and old WT, whereas they were increased only in old Null compared with respective young (n = 5-6/group, P < 0.05 for all). These results suggest that SPARC deletion delayed age-related cardiac inflammation. To further assess how SPARC affects inflammation, we stimulated peritoneal macrophages with SPARC (n = 4). SPARC treatment increased expression of proinflammatory macrophage M1 markers and decreased anti-inflammatory M2 markers. Echocardiography (n = 7-10/group) revealed an age-related increase in wall thickness of the left ventricle in WT (0.76 +/- 0.02 mm in young vs. 0.91 +/- 0.03 mm in old; P < 0.05) but not in Null (0.78 +/- 0.01 mm in young vs. 0.84 +/- 0.02 mm in old). In conclusion, SPARC deletion delayed age-related increases in macrophage infiltration and proinflammatory cytokine expression in vivo and in vitro. SPARC acts as an important mediator of age-related cardiac inflammation by increasing the expression of macrophage M1 markers and decreasing M2 markers.

AB Obesity is a serious chronic disease that increases the risk of numerous co-morbidities including metabolic syndrome, cardiovascular disease and cancer as well as increases risk of mortality, leading some to suggest this condition represents accelerated aging. Obesity is associated with significant increases in oxidative stress in vivo and, despite the well-explored relationship between oxidative stress and aging, the role this plays in the increased mortality of obese subjects remains an unanswered question. Here, we addressed this by undertaking a comprehensive, longitudinal study of a group of high fat-fed obese mice and assessed both their changes in oxidative stress and in their performance in physiological assays known to decline with aging. In female C57BL/6J mice fed a high-fat diet starting in adulthood, mortality was significantly increased as was oxidative damage in vivo. High fat-feeding significantly accelerated the decline in performance in several assays, including activity, gait, and rotarod. However, we also found that obesity had little effect on other markers of function and actually improved performance in grip strength, a marker of muscular function. Together, this first comprehensive assessment of longitudinal, functional changes in high fat-fed mice suggests that obesity may induce segmental acceleration of some of the aging process.

AB Background: Stroke disproportionately kills and disables ethnic minority seniors. Up to 30 % of ischemic strokes in the U.S. can be attributed to physical inactivity, yet most Americans, especially older racial/ethnic minorities, fail to participate in regular physical activity. We are conducting a randomized controlled trial (RCT) to test a culturally-tailored community-based walking intervention designed to reduce stroke risk by increasing physical activity among African American, Latino, Chinese, and Korean seniors with hypertension. We hypothesize that the intervention will yield meaningful changes in seniors' walking levels and stroke risk with feasibility to sustain and scale up across the aging services network.
Methods/Design: In this randomized single-blind wait-list control study, high-risk ethnic minority seniors are enrolled at senior centers, complete baseline data collection, and are randomly assigned to receive the intervention "Worth the Walk" immediately (N = 120, intervention group) or in 90 days upon completion of follow-up data collection (N = 120, control group). Trained case managers employed by the senior centers implement hour-long intervention sessions twice weekly for four consecutive weeks to the intervention group. Research staff blinded to participants' group assignment collect outcome data from both intervention and wait-list control participants 1 and 3-months after baseline data collection. Primary outcome measures are mean steps/day over 7 days, stroke knowledge, and self-efficacy for reducing stroke risk. Secondary and exploratory outcome measures include selected biological markers of health, healthcare seeking, and health-related quality of life. Outcomes will be compared between the two groups using standard analytic methods for randomized trials. We will conduct a formal process evaluation to assess barriers and facilitators to successful integration of Worth the Walk into the aging services network and to calculate estimated costs to sustain and scale up the intervention. Data collection is scheduled to be completed in December 2016.
Discussion: If this RCT demonstrates superior improvements in physical activity and stroke knowledge in the intervention group compared to the control group and is found to be sustainable and scalable, Worth the Walk could serve as a primary stroke prevention model for racial/ethnic communities across the nation.

AB BACKGROUNDAmong patients with stage I breast cancer, there is significant uncertainty concerning the optimal threshold at which to consider chemotherapy, and when considered, there is controversy regarding whether to consider non-intensive versus intensive regimens. The authors examined the types and costs of adjuvant chemotherapy received among patients with stage I breast cancer.
METHODSThe current study was a prospective cohort study including patients with stage I breast cancer who were treated at a National Comprehensive Cancer Network center from 2000 through 2009. Stage was defined according to the version of the American Joint Committee on Cancer Staging Manual applicable at the time of diagnosis. Stratifying by human epidermal growth factor receptor 2 (HER2), the authors examined the percentage of patients receiving intensive versus non-intensive chemotherapy regimens and the factors associated with type of chemotherapy administered using multivariable logistic regression. Costs of the most common regimens were estimated.
RESULTSOf 8907 patients, 33% received adjuvant chemotherapy. Among those individuals, there was an increase in the use of intensive chemotherapy within the last decade, from 31% in 2000 through 2005 to 63% in 2008 through 2009 (including an increase in the use of the combination of docetaxel, carboplatin, and trastuzumab) among patients with HER2-positive disease and from 15% in 2000 through 2005 to 41% in 2008 through 2009 among patients with HER2-negative disease (32% of patients with hormone receptor-positive and 59% of patients with triple-negative disease). Among patients treated with non-intensive regimens, there was an increase in the use of the combination of docetaxel and cyclophosphamide noted, with a decrease in the use of the doxorubicin and cyclophosphamide combination. The choice of regimen varied significantly by institution. The major drivers of cost variation were the incorporation of biologics (eg, trastuzumab) and growth factors, with significant variation even within non-intensive and intensive regimens.
CONCLUSIONSOver time, there was an increase in use of intensive regimens among Stage I breast cancer, with striking institutional and cost variations. Cancer 2015;121:1937-1948. (c) 2015 American Cancer Society.
Adjuvant chemotherapy use among patients with stage I breast cancer has changed significantly over time. There has been an intensification of treatment and an increase in the use of taxane-based regimens, with a reduction in concomitant anthracycline-based regimens. Striking institutional variations reflect a lack of certainty regarding the optimal regimens for these patients.

AB Background: Because little was previously known about Asian-American patients with heart failure (HF), we compared clinical profiles, quality of care, and outcomes between Asian-American and non-Hispanic white HF patients using data from the American Heart Association Get With The Guidelines-Heart Failure (GWTG-HF) program.
Methods: We analyzed 153,023 HF patients (149,249 whites, 97.5%; 3774 Asian-Americans, 2.5%) from 356 U.S. centers participating in the GWTG-HF program(2005-2012). Baseline characteristics, quality of caremetrics, in-hospital mortality, discharge to home, and length of stay were examined.
Results: Relative to white patients, Asian-American HF patients were younger, more likely to be male, uninsured or covered by Medicaid, and recruited in the western region. They had higher prevalence of diabetes, hypertension, and renal insufficiency, but similar ejection fraction. Overall, Asian-American HF patients had comparable quality of care except that they were less likely to receive aldosterone antagonists at discharge (relative risk < RR >, 0.88; 95% confidence interval < CI >, 0.78-0.99), and anticoagulation for atrial fibrillation (RR, 0.91; 95% CI, 0.85-0.97) even after risk adjustment. Compared with white patients, Asian-American patients had comparable risk adjusted in-hospital mortality (RR, 1.11; 95% CI, 0.91-1.35), length of stay > 4 days (RR, 1.01; 95% CI, 0.95-1.08), and were more likely to be discharged to home (RR, 1.08; 95% CI, 1.06-1.11).
Conclusions: Despite some differences in clinical profiles, Asian-American patients hospitalized with HF receive very similar quality of care and have comparable health outcomes to their white counterparts. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

AB BackgroundIn the United States, half of men with prostate cancer harbor the androgen-regulated gene fusion TMPRSS2:ERG. We hypothesized that men with TMPRSS2:ERG positive tumors are more responsive to androgen deprivation therapy (ADT).
MethodsWe studied a cohort of 239 men with prostate cancer from the Physicians' Health Study and Health Professionals Follow-up Study who received ADT during their disease course. Fusion status was assessed on available tumor tissue by immunohistochemistry for ERG protein expression. We used Cox models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for assessment of prostate cancer-specific mortality after ADT initiation.
ResultsRoughly half of the men had stage T3 or higher tumors at diagnosis and 39% had Gleason 8-10 tumors. During an average follow up of 10.2 years, 42 men died from prostate cancer. There was a non-significant inverse association between positive fusion status and time to death from prostate cancer after ADT (multivariable HR: 0.76; 95% CI: 0.40-1.45). Harboring the TMPRSS2:ERG fusion was associated with a statistically significant lower risk of prostate cancer mortality among men who were treated with orchiectomy (multivariable HR: 0.13; 95% CI: 0.03-0.62), based on 15 events.
ConclusionsOur results, combined with those from earlier studies, provide suggestive evidence that men with TMPRSS2:ERG positive tumors may have longer prostate cancer survival after ADT. Larger cohorts are needed for more robust results and to assess whether men with tumors harboring the fusion benefit from treatment with ADT in the (neo) adjuvant or metastatic setting specifically.

AB Researchers are actively pursuing the development of a new non-invasive test (NIT) for colorectal cancer (CRC) screening as an alternative to fecal occult blood tests (FOBTs). The majority of pilot studies focus on the detection of invasive CRC rather than precursor lesions (i.e., adenomas). We aimed to explore the relevance of adenoma detection for the viability of an NIT for CRC screening by considering a hypothetical test that does not detect adenomas beyond chance. We used the Simulation Model of Colorectal Cancer (SimCRC) to estimate the effectiveness of CRC screening and the lifetime costs (payers' perspective) for a cohort of US 50-years-old persons to whom CRC screening is offered from age 50-75. We compared annual screening with guaiac and immunochemical FOBTs (with sensitivities up to 70 and 24% for CRC and adenomas, respectively) to annual screening with a hypothetical NIT (sensitivity of 90% for CRC, no detection of adenomas beyond chance, specificity and cost similar to FOBTs). Screening with the NIT was not more effective, but was 29-44% more costly than screening with FOBTs. The findings were robust to varying the screening interval, the NIT's sensitivity for CRC, adherence rates favoring the NIT, and the NIT's unit cost. A comparative modelling approach using a model that assumes a shorter adenoma dwell time (MISCAN-COLON) confirmed the superiority of the immunochemical FOBT over an NIT with no ability to detect adenomas. Information on adenoma detection is crucial to determine whether a new NIT is a viable alternative to FOBTs for CRC screening. Current evidence thus lacks an important piece of information to identify marker candidates that hold real promise and deserve further (large-scale) evaluation.
What's new? The development of new non-invasive tests (NITs) for colorectal cancer (CRC) screening has centered primarily on improving the detection of invasive disease. But according to this study, whether new NITs are viable alternatives to immunochemical fecal occult blood testsalready established screening tests for CRC-depends also on their ability to detect adenomas, the precursor lesions of CRC. Without that ability, immunochemical fecal occult blood tests retain their superiority over newer NITs, many of which attempt to detect biomarkers in stool or blood. The identification of adenoma-specific markers could be critical to the advance of NITs for CRC screening.

AB The goal of the present study was to determine whether pre-hospital 25-hydroxyvitamin D (25(OH)D) levels are associated with the risk of hospital-acquired new-onset delirium (HANOD). We performed a retrospective cohort study of 4508 adult inpatients at two teaching hospitals in Boston from 1993 to 2006. All patients had 25(OH)D levels measured before hospital admission. The main outcome measure was HANOD, defined as the onset of delirium during an acute care hospitalisation. Patients with a history of delirium or dementia, or those with a diagnosis of delirium or dementia upon acute care hospitalisation were excluded from the analysis. To test the association of pre-hospital 25(OH)D levels with HANOD, we constructed a multivariable logistic regression model to adjust for clinically relevant covariates. Among our patient cohort, the mean 25(OH)D level was 22 (sd 13)ng/ml and approximately 4% of patients met the criteria for HANOD. Following adjustment for age, sex, race (non-white v. white), patient type (medical v. surgical) and Deyo-Charlson Index, patients with 25(OH)D levels <10, 10-19.9 and 20-29.9ng/ml had higher odds of HANOD than patients with 25(OH)D levels 30ng/ml: OR 2.15 (95% CI 1.32, 3.50), OR 1.54 (95% CI 0.98, 2.43) and OR 1.23 (95% CI, 0.76, 1.99), respectively. These data support the rationale for randomised, controlled trials to test the role of vitamin D supplementation in the prevention of HANOD.

AB Aims Edoxaban is an oral, once-daily factor Xa inhibitor that is non-inferior to well-managed warfarin in patients with atrial fibrillation (AF) for the prevention of stroke and systemic embolic events (SEEs). We examined the efficacy and safety of edoxaban vs. warfarin in patients who were vitamin K antagonist (VKA) naive or experienced.
Methods and results ENGAGE AF-TIMI 48 randomized 21 105 patients with AF at moderate-to-high risk of stroke to once-daily edoxaban vs. warfarin. Subjects were followed for a median of 2.8 years. The primary efficacy endpoint was stroke or SEE. As a pre-specified subgroup, we analysed outcomes for those with or without prior VKA experience (> 60 consecutive days). Higher-dose edoxaban significantly reduced the risk of stroke or SEE in patients who were VKA naive [hazard ratio (HR) 0.71, 95% confidence interval (CI) 0.56-0.90] and was similar to warfarin in the VKA experienced (HR 1.01, 95% CI 0.82-1.24; P interaction = 0.028). Lower-dose edoxaban was similar to warfarin for stroke or SEE prevention in patients who were VKA naive (HR 0.92, 95% CI 0.73-1.15), but was inferior to warfarin in those who were VKA experienced (HR 1.31, 95% 1.08-1.60; P interaction = 0.019). Both higher-dose and lower-dose edoxaban regimens significantly reduced the risk of major bleeding regardless of prior VKA experience (P interaction = 0.90 and 0.71, respectively).
Conclusion In patients with AF, edoxaban appeared to demonstrate greater efficacy compared with warfarin in patients who were VKA naive than VKA experienced. Edoxaban significantly reduced major bleeding compared with warfarin regardless of prior VKA exposure.

AB Background Myocarditis is characterized by inflammatory cell infiltration of the heart and subsequent deterioration of cardiac function. Monocytes are the most prominent population of accumulating leucocytes. We investigated whether in vivo administration of nanoparticle-encapsulated siRNA targeting chemokine (C-C motif) receptor 2 (CCR2)-a chemokine receptor crucial for leucocyte migration in humans and mice-reduces inflammation in autoimmune myocarditis.
Methods and results In myocardium of patients with myocarditis, CCL2 mRNA levels and CCR2(+) cells increased (P < 0.05), motivating us to pursue CCR2 silencing. Flow cytometric analysis showed that siRNA silencing of CCR2 (siCCR2) reduced the number of Ly6C(high) monocytes in hearts of mice with acute autoimmune myocarditis by 69% (P < 0.05), corroborated by histological assessment. The nanoparticle-delivered siRNA was not only active in monocytes but also in bone marrow haematopoietic progenitor cells. Treatment with siCCR2 reduced the migration of bone marrow granulocyte macrophage progenitors into the blood. Cellular magnetic resonance imaging (MRI) after injection of macrophage-avid magnetic nanoparticles detected myocarditis and therapeutic effects of RNAi non-invasively. Mice with acute myocarditis showed enhanced macrophage MRI contrast, which was prevented by siCCR2 (P < 0.05). Follow-up MRI volumetry revealed that siCCR2 treatment improved ejection fraction (P < 0.05 vs. control siRNA-treated mice).
Conclusion This study highlights the importance of CCR2 in the pathogenesis of myocarditis. In addition, we show that siCCR2 affects leucocyte progenitor trafficking. The data also point to a novel therapeutic strategy for the treatment of myocarditis.

We studied the use and outcomes of digoxin in patients in the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF).
Methods For this retrospective analysis, we included and classified patients from ROCKET AF on the basis of digoxin use at baseline and during the study. Patients in ROCKET AF were recruited from 45 countries and had AF and risk factors putting them at moderate-to-high risk of stroke, with or without heart failure. We used Cox proportional hazards regression models adjusted for baseline characteristics and drugs to investigate the association of digoxin with all-cause mortality, vascular death, and sudden death. ROCKET AF was registered with ClinicalTrials.gov, number NCT00403767.
Findings In 14 171 randomly assigned patients, digoxin was used at baseline in 5239 (37%). Patients given digoxin were more likely to be female (42% vs 38%) and have a history of heart failure (73% vs 56%), diabetes (43% vs 38%), and persistent AF (88% vs 77%; p<0.0001 for each comparison). After adjustment, digoxin was associated with increased all-cause mortality (5.41 vs 4.30 events per 100 patients-years; hazard ratio 1.17; 95% CI 1.04-1.32; p=0.0093), vascular death (3.55 vs 2.69 per 100 patient-years; 1.19; 1.03-1.39, p=0.0201), and sudden death (1.68 vs 1.12 events per 100 patient-years; 1.36; 1.08-1.70, p=0.0076).
Interpretation Digoxin treatment was associated with a significant increase in all-cause mortality, vascular death, and sudden death in patients with AF. This association was independent of other measured prognostic factors, and although residual confounding could account for these results, these data show the possibility of digoxin having these effects. A randomised trial of digoxin in treatment of AF patients with and without heart failure is needed.

AB To identify genetic and environmental factors contributing to the pathogenesis of nonalcoholic fatty liver disease, we examined liver steatosis and related clinical and molecular traits in more than 100 unique inbred mouse strains, which were fed a diet rich in fat and carbohydrates. A > 30-fold variation in hepatic TG accumulation was observed among the strains. Genome-wide association studies revealed three loci associated with hepatic TG accumulation. Utilizing transcriptomic data from the liver and adipose tissue, we identified several high-confidence candidate genes for hepatic steatosis, including Gde1, a glycerophosphodiester phosphodiesterase not previously implicated in triglyceride metabolism. We confirmed the role of Gde1 by in vivo hepatic over-expression and shRNA knockdown studies. We hypothesize that Gde1 expression increases TG production by contributing to the production of glycerol-3-phosphate. Our multi-level data, including transcript levels, metabolite levels, and gut microbiota composition, provide a framework for understanding genetic and environmental interactions underlying hepatic steatosis.

AB People vary substantially in their ability to acquire and maintain social ties. Here, we use a combined epidemiological and individual differences approach to understand the childhood roots of adult social cognitive functioning. We assessed exposure to 25 forms of traumatic childhood experiences in over 5000 adults, along with measures of face discrimination, face memory, theory of mind, social motivation, and social support. Retrospectively-reported experiences of parental maltreatment in childhood (particularly physical abuse) were the most broadly and robustly associated with adult variations in theory of mind, social motivation, and social support. Adult variations in face discrimination and face memory, on the other hand, were not significantly associated with exposure to childhood adversity. Our findings indicate domains of social cognition that may be particularly vulnerable to the effects of adverse childhood environments, and suggest mechanisms whereby environmental factors might influence the development of social abilities.

AB Purpose: Epiretinal fibrovascular membranes (FVMs) are a hallmark of proliferative diabetic retinopathy (PDR). Surgical removal of FVMs is often indicated to treat tractional retinal detachment. This potentially informative pathological tissue is usually disposed of after surgery without further examination. We developed a method for isolating and characterizing cells derived from FVMs and correlated their expression of specific markers in culture with that in tissue.
Methods: FVMs were obtained from 11 patients with PDR during diabetic vitrectomy surgery and were analyzed with electron microscopy (EM), comparative genomic hybridization (CGH), immunohistochemistry, and/or digested with collagenase II for cell isolation and culture. Antibody arrays and enzyme-linked immunosorbent assay (ELISA) were used to profile secreted angiogenesis-related proteins in cell culture supernatants.
Results: EM analysis of the FVMs showed abnormal vessels composed of endothelial cells with large nuclei and plasma membrane infoldings, loosely attached perivascular cells, and stromal cells. The cellular constituents of the FVMs lacked major chromosomal aberrations as shown with CGH. Cells derived from FVMs (C-FVMs) could be isolated and maintained in culture. The C-FVMs retained the expression of markers of cell identity in primary culture, which define specific cell populations including CD31-positive, alpha-smooth muscle actin-positive (SMA), and glial fibrillary acidic protein-positive (GFAP) cells. In primary culture, secretion of angiopoietin-1 and thrombospondin-1 was significantly decreased in culture conditions that resemble a diabetic environment in SMA-positive C-FVMs compared to human retinal pericytes derived from a non-diabetic donor.
Conclusions: C-FVMs obtained from individuals with PDR can be isolated, cultured, and profiled in vitro and may constitute a unique resource for the discovery of cell signaling mechanisms underlying PDR that extends beyond current animal and cell culture models.

AB Background: End-stage renal disease carries a prognosis similar to cancer yet only 20 % of end-stage renal disease patients are referred to hospice. Furthermore, conversations between dialysis team members and patients about end-of-life planning are uncommon. Lack of provider training about how to communicate prognostic data may contribute to the limited number of end-of-life care discussions that take place with this chronically ill population. In this study, we will test the Shared Decision-Making Renal Supportive Care communication intervention to systematically elicit patient and caretaker preferences for end-of-life care so that care concordant with patients' goals can be provided.
Methods/design: This multi-center study will deploy an intervention to improve end-of-life communication for hemodialysis patients who are at high risk of death in the ensuing six months. The intervention will be carried out as a prospective cohort with a retrospective cohort serving as the comparison group. Patients will be recruited from 16 dialysis units associated with two large academic centers in Springfield, Massachusetts and Albuquerque, New Mexico. Critical input from patient advisory boards, a stakeholder panel, and initial qualitative analysis of patient and caretaker experiences with advance care planning have informed the communication intervention. Rigorous communication training for hemodialysis social workers and providers will ensure that standardized study procedures are performed at each dialysis unit. Nephrologists and social workers will communicate prognosis and provide advance care planning in face-to-face encounters with patients and families using a social work-centered algorithm. Study outcomes including frequency and timing of hospice referrals, patient and caretaker satisfaction, quality of end-of-life discussions, and quality of death will be assessed over an 18 month period.
Discussion: The Shared Decision-Making Renal Supportive Care Communication intervention intends to improve discussions about prognosis and end-of-life care with end-stage renal disease patients. We anticipate that the intervention will help guide hemodialysis staff and providers to effectively participate in advance care planning for patients and caretakers to establish preferences and goals at the end of life.

AB Circulating tumor cells (CTCs) are seeds for cancer metastasis and are predictive of poor prognosis in breast cancer patients. Whether CTCs and primary tumor cells (PTCs) respond to chemotherapy differently is not known. Here, we show that CTCs of breast cancer are more resistant to chemotherapy than PTCs because of potentiated DNA repair. Surprisingly, the chemoresistance of CTCs was recapitulated in PTCs when they were detached from the extracellular matrix. Detachment of PTCs increased the levels of reactive oxygen species and partially activated the DNA damage checkpoint, converting PTCs to a CTC-like state. Inhibition of checkpoint kinases Chk1 and Chk2 in CTCs reduces the basal checkpoint response and sensitizes CTCs to DNA damage in vitro and in mouse xenografts. Our results suggest that DNA damage checkpoint inhibitors may benefit the chemotherapy of breast cancer patients by sup-pressing the chemoresistance of CTCs and reducing the risk of cancer metastasis.

AB Human APOE beta 4 allele is a strong genetic risk factor of Alzheimer disease. Neuropathological and genetic studies suggested that apolipoprotein E4 (apoE4) protein facilitates deposition of amyloid beta peptide (A beta) in the brain, although the mechanism whereby apoE4 increases amyloid aggregates remains elusive. Here we show that injection of A beta protofibrils induced A beta deposition in the brain of APP transgenic mice, suggesting that A beta protofibrils acted as a seed for aggregation and deposition of A beta in vivo. Injection of A beta protofibrils together with apoE3 significantly attenuated A beta deposition, whereas apoE4 did not have this effect. In vitro assays revealed that the conversion of A beta protofibrils to fibrils progressed more slowly upon coincubation with apoE2 or apoE3 compared with that with apoE4. A beta protofibrils complexed with apoE4 were less stable than those with apoE2 or apoE3. These data suggest that the suppression effect of apoE2 or apoE3 on the structural conversion of A beta protofibrils to fibrils is stronger than those of apoE4, thereby impeding beta-amyloid deposition.

AB Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. Recent technological advances have illuminated the role of GABAergic neurons in control of cortical arousal and sleep. Sleep-promoting GABAergic neurons in the preoptic hypothalamus are well-known. Less well-appreciated are GABAergic projection neurons in the brainstem, midbrain, hypothalamus, and basal forebrain, which paradoxically promote arousal and fast electroencephalographic (EEG) rhythms. Thus, GABA is not purely a sleep-promoting neurotransmitter. GABAergic projection neurons in the brainstem nucleus incertus and ventral tegmental nucleus of Gudden promote theta (4-8 Hz) rhythms. Ventral tegmental area GABAergic neurons, neighboring midbrain dopamine neurons, project to the frontal cortex and nucleus accumbens. They discharge faster during cortical arousal and regulate reward. Thalamic reticular nucleus GABAergic neurons initiate sleep spindles in non-REM sleep. In addition, however, during wakefulness, they tonically regulate the activity of thalamocortical neurons. Other GABAergic inputs to the thalamus arising in the globus pallidus pars intema, substantia nigra pars reticulata, zona incerta, and basal forebrain regulate motor activity, arousal, attention, and sensory transmission. Several subpopulations of cortically projecting GABAergic neurons in the basal forebrain project to the thalamus and neocortex and preferentially promote cortical gamma-band (30-80 Hz) activity and wakefulness. Unlike sleep-active GABAergic neurons, these ascending GABAergic neurons are fast-firing neurons which disinhibit and synchronize the activity of their forebrain targets, promoting the fast EEG rhythms typical of conscious states. They are prominent targets of GABAergic hypnotic agents. Understanding the properties of ascending GABAergic neurons may lead to novel treatments for diseases involving disorders of cortical activation and wakefulness.

AB Realizations of low firing rates in neural networks usually require globally balanced distributions among excitatory and inhibitory links, while feasibility of temporal coding is limited by neuronal millisecond precision. We show that cooperation, governing global network features, emerges through nodal properties, as opposed to link distributions. Using in vitro and in vivo experiments we demonstrate microsecond precision of neuronal response timings under low stimulation frequencies, whereas moderate frequencies result in a chaotic neuronal phase characterized by degraded precision. Above a critical stimulation frequency, which varies among neurons, response failures were found to emerge stochastically such that the neuron functions as a low pass filter, saturating the average inter-spike-interval. This intrinsic neuronal response impedance mechanism leads to cooperation on a network level, such that firing rates are suppressed toward the lowest neuronal critical frequency simultaneously with neuronal microsecond precision. Our findings open up opportunities of controlling global features of network dynamics through few nodes with extreme properties.

AB Genome sequencing has uncovered a new mutational phenomenon in cancer and congenital disorders called chromothripsis. Chromothripsis is characterized by extensive genomic rearrangements and an oscillating pattern of DNA copy number levels, all curiously restricted to one or a few chromosomes. The mechanism for chromothripsis is unknown, but we previously proposed that it could occur through the physical isolation of chromosomes in aberrant nuclear structures called micronuclei. Here, using a combination of live cell imaging and single-cell genome sequencing, we demonstrate that micronucleus formation can indeed generate a spectrum of genomic rearrangements, some of which recapitulate all known features of chromothripsis. These events are restricted to the mis-segregated chromosome and occur within one cell division. We demonstrate that the mechanism for chromothripsis can involve the fragmentation and subsequent reassembly of a single chromatid from a micronucleus. Collectively, these experiments establish a new mutational process of which chromothripsis is one extreme outcome.

AB Metabolic endotoxemia, commonly derived from gut dysbiosis, is a primary cause of chronic low grade inflammation that underlies many chronic diseases. Here we show that mice fed a diet high in omega-6 fatty acids exhibit higher levels of metabolic endotoxemia and systemic low-grade inflammation, while transgenic conversion of tissue omega-6 to omega-3 fatty acids dramatically reduces endotoxemic and inflammatory status. These opposing effects of tissue omega-6 and omega-3 fatty acids can be eliminated by antibiotic treatment and animal co-housing, suggesting the involvement of the gut microbiota. Analysis of gut microbiota and fecal transfer revealed that elevated tissue omega-3 fatty acids enhance intestinal production and secretion of intestinal alkaline phosphatase (IAP), which induces changes in the gut bacteria composition resulting in decreased lipopolysaccharide production and gut permeability, and ultimately, reduced metabolic endotoxemia and inflammation. Our findings uncover an interaction between host tissue fatty acid composition and gut microbiota as a novel mechanism for the anti-inflammatory effect of omega-3 fatty acids. Given the excess of omega-6 and deficiency of omega-3 in the modern Western diet, the differential effects of tissue omega-6 and omega-3 fatty acids on gut microbiota and metabolic endotoxemia provide insight into the etiology and management of today's health epidemics.

AB Background: Carbonic anhydrase (CA) IX is a surface-expressed protein that is upregulated by the hypoxia inducible factor (HIF) and represents a prototypic tumor-associated antigen that is overexpressed on renal cell carcinoma (RCC). Therapeutic approaches targeting CAIX have focused on the development of CAIX inhibitors and specific immunotherapies including monoclonal antibodies (mAbs). However, current in vivo mouse models used to characterize the anti-tumor properties of fully human anti-CAIX mAbs have significant limitations since the role of human effector cells in tumor cell killing in vivo is not directly evaluated.
Methods: The role of human anti-CAIX mAbs on CAIX(+) RCC tumor cell killing by immunocytes or complement was tested in vitro by antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC) and antibody-dependent cellular phagocytosis (ADCP) as well as on CAIX(+) RCC cellular motility, wound healing, migration and proliferation. The in vivo therapeutic activity mediated by anti-CAIX mAbs was determined by using a novel orthotopic RCC xenograft humanized animal model and analyzed by histology and FACS staining.
Results: Our studies demonstrate the capacity of human anti-CAIX mAbs that inhibit CA enzymatic activity to result in immune-mediated killing of RCC, including nature killer (NK) cell-mediated ADCC, CDC, and macrophage-mediated ADCP. The killing activity correlated positively with the level of CAIX expression on RCC tumor cell lines. In addition, Fc engineering of anti-CAIX mAbs was shown to enhance the ADCC activity against RCC. We also demonstrate that these anti-CAIX mAbs inhibit migration of RCC cells in vitro. Finally, through the implementation of a novel orthotopic RCC model utilizing allogeneic human peripheral blood mononuclear cells in NOD/SCID/IL2R gamma(-/-) mice, we show that anti-CAIX mAbs are capable of mediating human immune response in vivo including tumor infiltration of NK cells and activation of T cells, resulting in inhibition of CAIX(+) tumor growth.
Conclusions: Our findings demonstrate that these novel human anti-CAIX mAbs have therapeutic potential in the unmet medical need of targeted killing of HIF-driven CAIX+ RCC. The orthotopic tumor xenografted humanized mouse provides an improved model to evaluate the in vivo anti-tumor capabilities of fully human mAbs for RCC therapy.

EXPRESSION
AB Epstein-Barr virus-positive diffuse large B-cell lymphoma of the elderly (EBV+ DLBCL-e) is a molecularly distinct variant of DLBCL, characterized by a monoclonal B-cell proliferation that occurs in patients >50 years of age without a history or clinicopathologic evidence of immunodeficiency. However, patients with EBV+ DLBCL younger than 50-years-old also exist in Western countries. We evaluated the clinicopathologic, immunophenotypic and genetic features in Cacausian patients with EBV+ DLBCL who are <= 50 years of age and compared this patient group to patients who are >50 years. In patients who are <= 50 years, less frequent expression of BCL6 and a trend of more frequent expression of CD30 and pSTAT3 were found in patients with EBV+ DLBCL. In patients who are >50 years, common expression of CD30, p50, pSTAT3 and less frequent expression of BCL6 were observed. Older patients also more commonly had a poor performance status (ECOG >= 2). Comparing EBV+ DLBCL patients in <= 50 years versus >50 years, both groups had similar clinicopathologic, immunophenotypic and genetic features. Gene expression profiling, microRNA profiling and treatment outcome of the younger patients with EBV+ DLBCL was not distinctive from tumors in older patients. Based on our data, we suggest that the arbitrary age cutoff for EBV+ DLBCL is unnecessary and should be eliminated in the WHO lymphoma classification scheme.

TI Impaired Cellular Immunity in the Murine Neural Crest Conditional
Deletion of Endothelin Receptor-B Model of Hirschsprung's Disease
SO PLOS ONE

AB Hirschsprung's disease (HSCR) is characterized by aganglionosis from failure of neural crest cell (NCC) migration to the distal hindgut. Up to 40% of HSCR patients suffer Hirschsprung's-associated enterocolitis (HAEC), with an incidence that is unchanged from the pre-operative to the post-operative state. Recent reports indicate that signaling pathways involved in NCC migration may also be involved in the development of secondary lymphoid organs. We hypothesize that gastrointestinal (GI) mucosal immune defects occur in HSCR that may contribute to enterocolitis. EdnrB was deleted from the neural crest (EdnrB(NCC-/-)) resulting in mutants with defective NCC migration, distal colonic aganglionosis and the development of enterocolitis. The mucosal immune apparatus of these mice was interrogated at post-natal day (P) 2124, prior to histological signs of enterocolitis. We found that EdnrB(NCC-/-) display lymphopenia of their Peyer's Patches, the major inductive site of GI mucosal immunity. EdnrB(NCC-/-) Peyer's Patches demonstrate decreased B-lymphocytes, specifically IgM(+)IgD(hi) (Mature) B-lymphocytes, which are normally activated and produce IgA following antigen presentation. EdnrB(NCC-/-) animals demonstrate decreased small intestinal secretory IgA, but unchanged nasal and bronchial airway secretory IgA, indicating a gut-specific defect in IgA production or secretion. In the spleen, which is the primary source of IgA-producing Mature B-lymphocytes, EdnrB(NCC-/-) animals display decreased B-lymphocytes, but an increase in Mature B-lymphocytes. EdnrB(NCC-/-) spleens are also small and show altered architecture, with decreased red pulp and a paucity of B-lymphocytes in the germinal centers and marginal zone. Taken together, these findings suggest impaired GI mucosal immunity in EdnrB(NCC-/-) animals, with the spleen as a potential site of the defect. These findings build upon the growing body of literature that suggests that intestinal defects in HSCR are not restricted to the aganglionic colon but extend proximally, even into the ganglionated small intestine and immune cells.

TI A Defensin from the Model Beetle Tribolium castaneum Acts
Synergistically with Telavancin and Daptomycin against Multidrug

AB The red flour beetle Tribolium castaneum is a common insect pest and has been established as a model beetle to study insect development and immunity. This study demonstrates that defensin 1 from T. castaneum displays in vitro and in vivo antimicrobial activity against drug resistant Staphylococcus aureus strains. The minimum inhibitory concentration (MIC) of defensin 1 against 11 reference and clinical staphylococcal isolates was between 16-64 mu g/ml. The putative mode of action of the defensin peptide is disruption of the bacterial cell membrane. The antibacterial activity of defensin 1 was attenuated by salt concentrations of 1.56 mM and 25 mM for NaCl and CaCl2 respectively. Treatment of defensin 1 with the reducing agent dithiothreitol (DTT) at concentrations 1.56 to 3.13 mM abolished the antimicrobial activity of the peptide. In the presence of subinhibitory concentrations of antibiotics that also target the bacterial cell envelope such as telavancin and daptomycin, the MIC of the peptide was as low as 1 mu g/ml. Moreover, when tested against an S. aureus strain that was defective in D-alanylation of the cell wall, the MIC of the peptide was 0.5 mu g/ml. Defensin 1 exhibited no toxicity against human erythrocytes even at 400 mu g/ml. The in vivo activity of the peptide was validated in a Caenorhabditis elegans-MRSA liquid infection assay. These results suggest that defensin 1 behaves similarly to other cationic AMPs in its mode of action against S. aureus and that the activity of the peptide can be enhanced in combination with other antibiotics with similar modes of action or with compounds that have the ability to decrease D-alanylation of the bacterial cell wall.

TI Selective reporting in trials of high risk cardiovascular devices: cross
sectional comparison between premarket approval summaries and published
reports
SO BMJ-BRITISH MEDICAL JOURNAL
LA English
DT Article
ID MEDICAL DEVICES; PUBLICATION; CLINICALTRIALS.GOV; ACCESS; STENT; TIME
AB OBJECTIVE
To investigate characteristics of clinical trials and results on safety and effectiveness reported in US Food and Drug Administration (FDA) documents for recently approved high risk cardiovascular devices compared with the characteristics and results reported in peer reviewed publications.
DESIGN
A search of the publicly available FDA database was performed for all cardiovascular devices that received premarket approval from 1 January 2000 to 31 December 2010. For each study listed in the premarket approval documents, a Medline search was conducted to obtain the corresponding publication.
MAIN OUTCOME MEASURES
Clinical trial characteristics, primary endpoints, and safety and efficacy results in the FDA documents and corresponding publications.
RESULTS
106 cardiovascular devices received premarket approval from 1 January 2000 to 31 December 2010. FDA premarket approval documents for these devices contained 177 studies, of which 86 (49%) had been published by 1 January 2013. These 86 publications corresponded to 60 distinct devices. The mean time from FDA approval to publication in a peer reviewed journal was 6.5 months (range -4.8-7.5 years). In 22 (26%) of the 86 compared studies the number of participants enrolled in the study differed in the FDA summary and the corresponding publications. Of 152 primary endpoints identified in the FDA documents, in the corresponding publications three (2%) were labeled as secondary, 43 (28%) were unlabeled, and 15 (10%) were not found. Among the primary results, 69 (45%) were identical, 35 (23%) were similar, 17 (11%) were substantially different, and 31 (20%) could not be compared.
CONCLUSIONS
Many clinical trials for high risk cardiovascular devices approved by the FDA remain unpublished. Even when trials are published, the study population, primary endpoints, and results can differ substantially from data submitted to the FDA.

AB Purpose
Crizotinib is an oral kinase inhibitor approved for the treatment of ALK-rearranged non-small-cell lung cancer (NSCLC). The clinical benefits of crizotinib in patients with brain metastases have not been previously studied.
Patients and Methods
Patients with advanced ALK-rearranged NSCLC enrolled onto clinical trial PROFILE 1005 or 1007 (randomly assigned to crizotinib) were included in this retrospective analysis. Patients with asymptomatic brain metastases (nontarget or target lesions) were allowed to enroll. Tumor assessments were evaluated every 6 weeks using RECIST (version 1.1).
Results
At baseline, 31% of patients (275 of 888) had asymptomatic brain metastases; 109 had received no prior and 166 had received prior brain radiotherapy as treatment. Among patients with previously untreated asymptomatic brain metastases, the systemic disease control rate (DCR) at 12 weeks was 63% (95% CI, 54% to 72%), the intracranial DCR was 56% (95% CI, 46% to 66%), and the median intracranial time to progression (TTP) was 7 months (95% CI, 6.7 to 16.4). Among patients with previously treated brain metastases, the systemic DCR was 65% (95% CI, 57% to 72%), the intracranial DCR was 62% (95% CI, 54% to 70%), and the median intracranial TTP was 13.2 months (95% CI, 9.9 to not reached). Patients with systemic disease control were also likely to experience intracranial disease control at 12 weeks (correlation coefficient, 0.7652; P < .001). Among patients without baseline brain metastases who developed progressive disease (n = 253) after initiation of crizotinib, 20% were diagnosed with brain metastases.
Conclusion
Crizotinib was associated with systemic and intracranial disease control in patients with ALK-rearranged NSCLC who were ALK inhibitor naive and had brain metastases. However, progression of preexisting or development of new intracranial lesions while receiving therapy was a common manifestation of acquired resistance to crizotinib.

AB Purpose
To provide a more precise estimate of long-term survival observed for ipilimumab-treated patients with advanced melanoma, we performed a pooled analysis of overall survival (OS) data from multiple studies.
Methods
The primary analysis pooled OS data for 1,861 patients from 10 prospective and two retrospective studies of ipilimumab, including two phase III trials. Patients were previously treated (n = 1,257) or treatment naive (n = 604), and the majority of patients received ipilimumab 3 mg/kg (n = 965) or 10 mg/kg (n = 706). We also conducted a secondary analysis of OS data (n = 4,846) with an additional 2,985 patients from an expanded access program. OS rates were estimated using the Kaplan-Meier method.
Results
Among 1,861 patients, median OS was 11.4 months (95% CI, 10.7 to 12.1 months), which included 254 patients with at least 3 years of survival follow-up. The survival curve began to plateau around year 3, with follow-up of up to 10 years. Three-year survival rates were 22%, 26%, and 20% for all patients, treatment-naive patients, and previously treated patients, respectively. Including data from the expanded access program, median OS was 9.5 months (95% CI, 9.0 to 10.0 months), with a plateau at 21% in the survival curve beginning around year 3.
Conclusion
To our knowledge, this is the largest analysis of OS to date for ipilimumab-treated patients with advanced melanoma. We observed a plateau in the survival curve, beginning at approximately 3 years, which was independent of prior therapy or ipilimumab dose. These data add to the evidence supporting the durability of long-term survival in ipilimumab-treated patients with advanced melanoma. (C) 2015 by American Society of Clinical Oncology

AB Purpose
This study was designed to assess efficacy, safety, and predictors of response to iniparib in combination with gemcitabine and carboplatin in early-stage triple-negative and BRCA1/2 mutation-associated breast cancer.
Patients and Methods
This single-arm phase II study enrolled patients with stage I to IIIA (T >= 1 cm) estrogen receptor-negative (<= 5%), progesterone receptor-negative (<= 5%), and human epidermal growth factor receptor 2-negative or BRCA1/2 mutation-associated breast cancer. Neoadjuvant gemcitabine (1,000 mg/m(2) intravenously [IV] on days 1 and 8), carboplatin (area under curve of 2 IV on days 1 and 8), and iniparib (5.6 mg/kg IV on days 1, 4, 8, and 11) were administered every 21 days for four cycles, until the protocol was amended to six cycles. The primary end point was pathologic complete response (no invasive carcinoma in breast or axilla). All patients underwent comprehensive BRCA1/2 genotyping, and homologous recombination deficiency was assessed by loss of heterozygosity (HRD-LOH) in pretreatment core breast biopsies.
Results
Among 80 patients, median age was 48 years; 19 patients (24%) had germline BRCA1 or BRCA2 mutations; clinical stage was I (13%), IIA (36%), IIB (36%), and IIIA (15%). Overall pathologic complete response rate in the intent-to-treat population (n = 80) was 36% (90% CI, 27 to 46). Mean HRD-LOH scores were higher in responders compared with nonresponders (P = .02) and remained significant when BRCA1/2 germline mutations carriers were excluded (P = .021).
Conclusion
Preoperative combination of gemcitabine, carboplatin, and iniparib is active in the treatment of early-stage triple-negative and BRCA1/2 mutation-associated breast cancer. The HRD-LOH assay was able to identify patients with sporadic triple-negative breast cancer lacking a BRCA1/2 mutation, but with an elevated HRD-LOH score, who achieved a favorable pathologic response. Confirmatory controlled trials are warranted. (C) 2015 by American Society of Clinical Oncology

AB Purpose
The identification of patients with metastatic triple-negative breast cancer (mTNBC) who are expected to benefit from platinum-based chemotherapy is of interest. We conducted a single-arm phase II clinical trial of single-agent platinum for mTNBC with biomarker correlates.
Patients and Methods
Patients with mTNBC received first-or second-line cisplatin (75 mg/m(2)) or carboplatin (area under the concentration-time curve 6) by physician's choice once every 3 weeks. Coprimary end points were objective response rate (RR) and response prediction by p63/p73 gene expression. Secondary and exploratory end points included toxicity assessment, RR in cisplatin versus carboplatin, and RR in molecularly defined subgroups, including BRCA1/2 mutation carriers.
Results
Patients (N = 86; 69 as first-line therapy) received cisplatin (n = 43) or carboplatin (n = 43). RR was 25.6% (95% CI, 16.8% to 36%) and was numerically higher with cisplatin (32.6%) than with carboplatin (18.7%). RR was 54.5% in patients with germline BRCA1/2 mutations (n = 11). In patients without BRCA1/2 mutations (n = 66), exploratory analyses showed that a BRCA-like genomic instability signature (n = 32) discriminated responding and nonresponding tumors (mean homologous recombination deficiency-loss of heterozygosity/homologous recombination deficiency-large-scale state transitions [HRD-LOH/HRD-LST] scores were 12.68 and 5.11, respectively), whereas predefined analysis by p63/p73 expression status (n = 61), p53 and PIK3CA mutation status (n = 53), or PAM50 gene expression subtype (n = 55) did not. Five of the six long-term responders alive at a median of 4.5 years lacked germline BRCA1/2 mutations, and two of them had increased tumor HRD-LOH/HRD-LST scores.
Conclusion
Platinum agents are active in mTNBC, especially in patients with germline BRCA1/2 mutations. A measure of tumor DNA repair function may identify patients without mutations who could benefit from platinum therapy agents. Prospective controlled confirmatory trials are warranted.

AB Purpose
Thousands of children are living with advanced cancer; yet patient-reported outcomes (PROs) have rarely been used to describe their experiences. We aimed to describe symptom distress in 104 children age 2 years or older with advanced cancer enrolled onto the Pediatric Quality of Life and Evaluation of Symptoms Technology (PediQUEST) Study (multisite clinical trial evaluating an electronic PRO system).
Methods
Symptom data were collected using age-and respondent-adapted versions of the PediQUEST Memorial Symptom Assessment Scale (PQ-MSAS) at most once per week. Clinical and treatment data were obtained from medical records. Individual symptom scores were dichotomized into high/low distress. Determinants of PQ-MSAS scores were explored using linear mixed-effects models.
Results
During 9 months of follow-up, PQ-MSAS was administered 920 times: 459 times in teens (99% self-report), 249 times in children ages 7 to 12 years (96% child/ parent report), and 212 times in those ages 2 to 6 years (parent reports). Common symptoms included pain (48%), fatigue (46%), drowsiness (39%), and irritability (37%); most scores indicated high distress. Among the 73 PQ-MSAS surveys administered in the last 12 weeks of life, pain was highly prevalent (62%; 58% with high distress). Being female, having a brain tumor, experiencing recent disease progression, and receiving moderate-or high-intensity cancer-directed therapy in the prior 10 days were associated with worse PQ-MSAS scores. In the final 12 weeks of life, receiving mild cancer-directed therapy was associated with improved psychological PQ-MSAS scores.
Conclusion
Children with advanced cancer experience high symptom distress. Strategies to promote intensive symptom management are indicated, especially with disease progression or administration of intensive treatments. (C) 2015 by American Society of Clinical Oncology

AB Purpose The phase III North American Intergroup E2496 Trial (Combination Chemotherapy With or Without Radiation Therapy in Treating Patients With Hodgkin's Lymphoma) compared doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with mechlorethamine, doxorubicin, vincristine, bleomycin, vinblastine, etoposide, and prednisone (Stanford V). We report results of a planned subgroup analysis in patients with stage I or II bulky mediastinal Hodgkin lymphoma (HL).
Patients and Methods
Patients were randomly assigned to six to eight cycles of ABVD every 28 days or Stanford V once per week for 12 weeks. Two to 3 weeks after completion of chemotherapy, all patients received 36 Gy of modified involved field radiotherapy (IFRT) to the mediastinum, hila, and supraclavicular regions. Patients on the Stanford V arm received IFRT to additional sites >= 5 cm at diagnosis. Primary end points were failure-free survival (FFS) and overall survival (OS).
Results
Of 794 eligible patients, 264 had stage I or II bulky disease, 135 received ABVD, and 129 received Stanford V. Patient characteristics were matched. The overall response rate was 83% with ABVD and 88% with Stanford V. At a median follow-up of 6.5 years, the study excluded a difference of more than 21% in 5-year FFS and more than 16% in 5-year OS between ABVD and Stanford V (5-year FFS: 85% v 79%; HR, 0.68; 95% CI, 0.37 to 1.25; P = .22; 5-year OS: 96% v 92%; HR, 0.49; 95% CI, 0.16 to 1.47; P = .19). In-field relapses occurred in < 10% of the patients in each arm.
Conclusion
For patients with stage I or II bulky mediastinal HL, no substantial statistically significant differences were detected between the two regimens, although power was limited. To the best of our knowledge, this is the first prospective trial reporting outcomes specific to this subgroup, and it sets a benchmark for comparison of ongoing and future studies.

AB Innovative microfluidic technology has enabled massively parallelized and extremely efficient biological and clinical assays. Many biological applications developed and executed with traditional bulk processing techniques have been translated and streamlined through microfluidic processing with the notable exception of sample volume reduction or centrifugation, one of the most widely utilized processes in the biological sciences. We utilize the high-speed phenomenon known as inertial focusing combined with hydraulic resistance controlled multiplexed micro-siphoning allowing for the continuous concentration of suspended cells into pre-determined volumes up to more than 400 times smaller than the input with a yield routinely above 95% at a throughput of 240 ml/hour. Highlighted applications are presented for how the technology can be successfully used for live animal imaging studies, in a system to increase the efficient use of small clinical samples, and finally, as a means of macro-to-micro interfacing allowing large samples to be directly coupled to a variety of powerful microfluidic technologies.

AB Background-Epidemiological findings suggest a relationship between Alzheimer disease (AD), inflammation, and dyslipidemia, although the nature of this relationship is not well understood. We investigated whether this phenotypic association arises from a shared genetic basis.
Methods and Results-Using summary statistics (P values and odds ratios) from genome-wide association studies of >200 000 individuals, we investigated overlap in single-nucleotide polymorphisms associated with clinically diagnosed AD and C-reactive protein (CRP), triglycerides, and high-and low-density lipoprotein levels. We found up to 50-fold enrichment of AD single-nucleotide polymorphisms for different levels of association with C-reactive protein, low-density lipoprotein, high-density lipoprotein, and triglyceride single-nucleotide polymorphisms using a false discovery rate threshold <0.05. By conditioning on polymorphisms associated with the 4 phenotypes, we identified 55 loci associated with increased AD risk. We then conducted a meta-analysis of these 55 variants across 4 independent AD cohorts (total: n=29 054 AD cases and 114 824 healthy controls) and discovered 2 genome-wide significant variants on chromosome 4 (rs13113697; closest gene, HS3ST1; odds ratio=1.07; 95% confidence interval=1.05-1.11; P=2.86x10(-8)) and chromosome 10 (rs7920721; closest gene, ECHDC3; odds ratio=1.07; 95% confidence interval=1.04-1.11; P=3.38x10(-8)). We also found that gene expression of HS3ST1 and ECHDC3 was altered in AD brains compared with control brains.
Conclusions-We demonstrate genetic overlap between AD, C-reactive protein, and plasma lipids. By conditioning on the genetic association with the cardiovascular phenotypes, we identify novel AD susceptibility loci, including 2 genome-wide significant variants conferring increased risk for AD.

AB Dysregulation of the glutamate transporters EAAT1 and EAAT2 and their isoforms have been implicated in schizophrenia. EAAT1 and EAAT2 expression has been studied in different brain regions but the prevalence of astrocytic glutamate transporter expression masks the more subtle changes in excitatory amino acid transporters (EAATs) isoforms in neurons in the cortex. Using laser capture microdissection, pyramidal neurons were cut from the anterior cingulate cortex of postmortem schizophrenia (n = 20) and control (n = 20) subjects. The messenger RNA (mRNA) levels of EAAT1, EAAT2 and the splice variants EAAT1 exon9skipping, EAAT2 exon9skipping and EAAT2b were analyzed by real time PCR (RT-PCR) in an enriched population of neurons. Region-level expression of these transcripts was measured in postmortem schizophrenia (n = 25) and controls (n = 25). The relationship between selected EAAT polymorphisms and EAAT splice variant expression was also explored. Anterior cingulate cortex pyramidal cell expression of EAAT2b mRNA was increased (P<0.001; 67%) in schizophrenia subjects compared with controls. There was no significant change in other EAAT variants. EAAT2 exon9skipping mRNA was increased (P<0.05; 38%) at region level in the anterior cingulate cortex with no significant change in other EAAT variants at region level. EAAT2 single-nucleotide polymorphisms were significantly associated with changes in EAAT2 isoform expression. Haloperidol decanoate-treated animals, acting as controls for possible antipsychotic effects, did not have significantly altered neuronal EAAT2b mRNA levels. The novel finding that EAAT2b levels are increased in populations of anterior cingulate cortex pyramidal cells further demonstrates a role for neuronal glutamate transporter splice variant expression in schizophrenia.

ID BREAST-CANCER; OVARIAN SUPPRESSION; TAMOXIFEN
AB Results from two randomised global trials (SOFT & TEXT) designed to newly define the most effective components of adjuvant endocrine therapy for premenopausal women with endocrine responsive disease, showed that for some, those with high risk of relapse, the use of the aromatase inhibitor exemestane together with ovarian function suppression with GnRH analogue (triptorelin) yielded the most favourable treatment outcome compared with tamoxifen. For women with low risk of relapse, treatment with tamoxifen was similar to ovarian function suppression together with either exemestane or tamoxifen. For women with intermediate risk of relapse, ovarian function suppression added to tamoxifen was not inferior to exemestane, while it resulted in superior outcomes compared to tamoxifen alone. Now, these trials provide critical information for the adjuvant treatment of premenopausal women with endocrine responsive breast cancer and are important for the development of future trials for further improvement of adjuvant endocrine therapies for the younger population.

AB Background: Recent developments in genomic sequencing have advanced our understanding of the mutations underlying human malignancy. Melanoma is a prototype of an aggressive, genetically heterogeneous cancer notorious for its biologic plasticity and predilection towards developing resistance to targeted therapies. Evidence is rapidly accumulating that dysregulated epigenetic mechanisms (DNA methylation/demethylation, histone modification, non-coding RNAs) may play a central role in the pathogenesis of melanoma. Therefore, we sought to characterize the frequency and nature of mutations in epigenetic regulators in clinical, treatment-naive, patient melanoma specimens obtained from one academic institution.
Results: Targeted next-generation sequencing for 275 known and investigative cancer genes (of which 41 genes, or 14.9 %, encoded an epigenetic regulator) of 38 treatment-naive patient melanoma samples revealed that 22.3 % (165 of 740) of all non-silent mutations affected an epigenetic regulator. The most frequently mutated genes were BRAF, MECOM, NRAS, TP53, MLL2, and CDKN2A. Of the 40 most commonly mutated genes, 12 (30.0 %) encoded epigenetic regulators, including genes encoding enzymes involved in histone modification (MECOM, MLL2, SETD2), chromatin remodeling (ARID1B, ARID2), and DNA methylation and demethylation (TET2, IDH1). Among the 38 patient melanoma samples, 35 (92.1 %) harbored at least one mutation in an epigenetic regulator. The genes with the highest number of total UVB-signature mutations encoded epigenetic regulators, including MLL2 (100 %, 16 of 16) and MECOM (82.6 %, 19 of 23). Moreover, on average, epigenetic genes harbored a significantly greater number of UVB-signature mutations per gene than non-epigenetic genes (3.7 versus 2.4, respectively; p = 0.01). Bioinformatics analysis of The Cancer Genome Atlas (TCGA) melanoma mutation dataset also revealed a frequency of mutations in the 41 epigenetic genes comparable to that found within our cohort of patient melanoma samples.
Conclusions: Our study identified a high prevalence of somatic mutations in genes encoding epigenetic regulators, including those involved in DNA demethylation, histone modification, chromatin remodeling, and microRNA processing. Moreover, UVB-signature mutations were found more commonly among epigenetic genes than in non-epigenetic genes. Taken together, these findings further implicate epigenetic mechanisms, particularly those involving the chromatin-remodeling enzyme MECOM/EVI1 and histone-modifying enzyme MLL2, in the pathobiology of melanoma.

AB To ensure accurate genomic segregation, cells evolved the spindle assembly checkpoint (SAC), whose role in adult stem cells remains unknown. Inducible perturbation of a SAC kinase, Mps1, and its downstream effector, Mad2, in skeletal muscle stem cells shows the SAC to be critical for normal muscle growth, repair, and self-renewal of the stem cell pool. SAC-deficient muscle stem cells arrest in G1 phase of the cell cycle with elevated aneuploidy, resisting differentiation even under inductive conditions. p21(CIP1) is responsible for these SAC-deficient phenotypes. Despite aneuploidy's correlation with aging, we find that aged proliferating muscle stem cells display robust SAC activity without elevated aneuploidy. Thus, muscle stem cells have a two-step mechanism to safeguard their genomic integrity. The SAC prevents chromosome missegregation and, if it fails, p21(CIP1)-dependent G1 arrest limits cellular propagation and tissue integration. These mechanisms ensure that muscle stem cells with compromised genomes do not contribute to tissue homeostasis.

AB AMPK is a master regulator of cellular metabolism that exerts either oncogenic or tumor suppressor activity depending on context. Here, we report that the specific AMPK agonist GSK621 selectively kills acutemyeloid leukemia (AML) cells but spares normal hematopoietic progenitors. This differential sensitivity results from a unique synthetic lethal interaction involving concurrent activation of AMPK and mTORC1. Strikingly, the lethality of GSK621 in primary AML cells and AML cell lines is abrogated by chemical or genetic ablation of mTORC1 signaling. The same synthetic lethality between AMPK and mTORC1 activation is established in CD34-positive hematopoietic progenitors by constitutive activation of AKT or enhanced in AML cells by deletion of TSC2. Finally, cytotoxicity in AML cells from GSK621 involves the eIF2 alpha/ATF4 signaling pathway that specifically results from mTORC1 activation. AMPK activation may represent a therapeutic opportunity in mTORC1-overactivated cancers.

AB Despite the remarkable clinical response of melanoma harboring BRAF mutations to BRAF inhibitors (BRAFi), most tumors become resistant. Here, we identified the downregulation of the ubiquitin ligase RNF125 in BRAFi-resistant melanomas and demonstrated its role in intrinsic and adaptive resistance to BRAFi in cultures as well as its association with resistance in tumor specimens. Sox10/MITF expression correlated with and contributed to RNF125 transcription. Reduced RNF125 was associated with elevated expression of receptor tyrosine kinases (RTKs), including EGFR. Notably, RNF125 altered RTK expression through JAK1, which we identified as an RNF125 substrate. RNF125 bound to and ubiquitinated JAK1, prompting its degradation and suppressing RTK expression. Inhibition of JAK1 and EGFR signaling overcame BRAFi resistance in melanoma with reduced RNF125 expression, as shown in culture and in in vivo xenografts. Our findings suggest that combination therapies targeting both JAK1 and EGFR could be effective against BRAFi-resistant tumors with de novo low RNF125 expression.

AB Background: Tai Chi (TC) exercise improves balance and reduces falls in older, health-impaired adults. TC's impact on dual task (DT) gait parameters predictive of falls, especially in healthy active older adults, however, is unknown.
Purpose: To compare differences in usual and DT gait between long-term TC-expert practitioners and age-/gender-matched TC-naive adults, and to determine the effects of short-term TC training on gait in healthy, non-sedentary older adults.
Methods: A cross-sectional study compared gait in healthy TC-naive and TC-expert (24.5 +/- 12 years experience) older adults. TC-naive adults then completed a 6-month, two-arm, wait-list randomized clinical trial of TC training. Gait speed and stride time variability (Coefficient of Variation %) were assessed during 90 s trials of undisturbed and cognitive DT (serial subtractions) conditions.
Results: During DT, gait speed decreased (p < 0.003) and stride time variability increased (p < 0.004) in all groups. Cross-sectional comparisons indicated that stride time variability was lower in the TC-expert vs. TC-naive group, significantly so during DT (2.11 vs. 2.55%; p = 0.027); by contrast, gait speed during both undisturbed and DT conditions did not differ between groups. Longitudinal analyses of TC-naive adults randomized to 6 months of TC training or usual care identified improvement in DT gait speed in both groups. A small improvement in DT stride time variability (effect size = 0.2) was estimated with TC training, but no significant differences between groups were observed. Potentially important improvements after TC training could not be excluded in this small study.
Conclusion: In healthy active older adults, positive effects of short- and long-term TC were observed only under cognitively challenging DT conditions and only for stride time variability. DT stride time variability offers a potentially sensitive metric for monitoring TC's impact on fall risk with healthy older adults.

TI Traumatic Spinal Cord Injury in the United States, 1993-2012
SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION
LA English
DT Article
ID PREVALENCE; EPIDEMIOLOGY; MORTALITY
AB IMPORTANCE Acute traumatic spinal cord injury results in disability and use of health care resources, yet data on contemporary national trends of traumatic spinal cord injury incidence and etiology are limited.
OBJECTIVE To assess trends in acute traumatic spinal cord injury incidence, etiology, mortality, and associated surgical procedures in the United States from 1993 to 2012.
DESIGN, SETTING, AND PARTICIPANTS Analysis of survey data from the US Nationwide Inpatient Sample databases for 1993-2012, including a total of 63 109 patients with acute traumatic spinal cord injury.
MAIN OUTCOMES AND MEASURES Age-and sex-stratified incidence of acute traumatic spinal cord injury; trends in etiology and in-hospital mortality of acute traumatic spinal cord injury.
RESULTS In 1993, the estimated incidence of acute spinal cord injury was 53 cases (95% CI, 52-54 cases) per 1 million persons based on 2659 actual cases. In 2012, the estimated incidence was 54 cases (95% CI, 53-55 cases) per 1 million population based on 3393 cases (average annual percentage change, 0.2%; 95% CI, -0.5% to 0.9%). Incidence rates among the younger male population declined from 1993 to 2012: for age 16 to 24 years, from 144 cases/million (2405 cases) to 87 cases/million (1770 cases) (average annual percentage change, -2.5%; 95% CI, -3.3% to -1.8%); for age 25 to 44 years, from 96 cases/million (3959 cases) to 71 cases/million persons (2930 cases), (average annual percentage change, -1.2%; 95% CI, -2.1% to -0.3%). A high rate of increase was observed in men aged 65 to 74 years (from 84 cases/million in 1993 [695 cases] to 131 cases/million [1465 cases]; average annual percentage change, 2.7%; 95% CI, 2.0%-3.5%). The percentage of spinal cord injury associated with falls increased significantly from 28%(95% CI, 26%-30%) in 1997-2000 to 66%(95% CI, 64%-68%) in 2010-2012 in those aged 65 years or older (P <.001). Although overall in-hospital mortality increased from 6.6%(95% CI, 6.1%-7.0%) in 1993-1996 to 7.5% (95% CI, 7.0%-8.0%) in 2010-2012 (P <.001), mortality decreased significantly from 24.2% (95% CI, 19.7%-28.7%) in 1993-1996 to 20.1% (95% CI, 17.0%-23.2%) in 2010-2012 (P =.003) among persons aged 85 years or older.
CONCLUSIONS AND RELEVANCE Between 1993 and 2012, the incidence rate of acute traumatic spinal cord injury remained relatively stable but, reflecting an increasing population, the total number of cases increased. The largest increase in incidence was observed in older patients, largely associated with an increase in falls, and in-hospital mortality remained high, especially among elderly persons.

AB The signal-to-noise ratio (SNR), a commonly used measure of fidelity in physical systems, is defined as the ratio of the squared amplitude or variance of a signal relative to the variance of the noise. This definition is not appropriate for neural systems in which spiking activity is more accurately represented as point processes. We show that the SNR estimates a ratio of expected prediction errors and extend the standard definition to one appropriate for single neurons by representing neural spiking activity using point process generalized linear models (PP-GLM). We estimate the prediction errors using the residual deviances from the PP-GLM fits. Because the deviance is an approximate chi(2) random variable, we compute a bias-corrected SNR estimate appropriate for single-neuron analysis and use the bootstrap to assess its uncertainty. In the analyses of four systems neuroscience experiments, we show that the SNRs are -10 dB to -3 dB for guinea pig auditory cortex neurons, -18 dB to -7 dB for rat thalamic neurons, -28 dB to -14 dB for monkey hippocampal neurons, and -29 dB to -20 dB for human subthalamic neurons. The new SNR definition makes explicit in the measure commonly used for physical systems the often-quoted observation that single neurons have low SNRs. The neuron's spiking history is frequently a more informative covariate for predicting spiking propensity than the applied stimulus. Our new SNR definition extends to any GLM system in which the factors modulating the response can be expressed as separate components of a likelihood function.

AB B-cell lymphoma 2 (BCL-2) ovarian killer (BOK) is a BCL-2 family protein with high homology to the multidomain proapoptotic proteins BAX and BAK, yet Bok(-/-) and even Bax(-/-) Bok(-/-) and Bak(-/-) Bok(-/-) mice were reported to have no overt phenotype or apoptotic defects in response to a host of classical stress stimuli. These surprising findings were interpreted to reflect functional compensation among the BAX, BAK, and BOK proteins. However, BOK cannot compensate for the severe apoptotic defects of Bax(-/-) Bak(-/-) mice despite its widespread expression. Here, we independently developed Bok(-/-) mice and found that Bok(-/-) cells are selectively defective in their response to endoplasmic reticulum (ER) stress stimuli, consistent with the predominant subcellular localization of BOK at the ER. Whereas Bok(-/-) mouse embryonic fibroblasts exposed to thapsigargin, A23187, brefeldin A, DTT, geldanamycin, or bortezomib manifested reduced activation of the mitochondrial apoptotic pathway, the death response to other stimuli such as etoposide, staurosporine, or UV remained fully intact. Multiple organs in Bok(-/-) mice exhibited resistance to thapsigargin-induced apoptosis in vivo. Although the ER stress agents activated the unfolded protein response, both ATF4 and CHOP activation were diminished in Bok(-/-) cells and mice. Importantly, BAX and BAK were unable to compensate for the defective apoptotic response to ER stress observed in SV40-transformed and primary Bok(-/-) cells, and in vivo. These findings support a selective and distinguishing role for BOK in regulating the apoptotic response to ER stress, revealing-to our knowledge-the first bona fide apoptotic defect linked to Bok deletion.

AB Multidrug-resistant Enterococcus faecalis possess numerous mobile elements that encode virulence and antibiotic resistance traits as well as new metabolic pathways, often constituting over one-quarter of the genome. It was of interest to determine how this large accretion of mobile elements affects competitive growth in the gastrointestinal (GI) tract consortium. We unexpectedly observed that the prototype clinical isolate strain V583 was actively killed by GI tract flora, whereas commensal enterococci flourished. It was found that killing of V583 resulted from lethal cross-talk between accumulated mobile elements and that this cross-talk was induced by a heptapeptide pheromone produced by native E. faecalis present in the fecal consortium. These results highlight two important aspects of the evolution of multidrug-resistant enterococci: (i) the accretion of mobile elements in E. faecalis V583 renders it incompatible with commensal strains, and (ii) because of this incompatibility, multidrug-resistant strains sharing features found in V583 cannot coexist with commensal strains. The accumulation of mobile elements in hospital isolates of enterococci can include those that are inherently incompatible with native flora, highlighting the importance of maintaining commensal populations as means of preventing colonization and subsequent infection by multidrug-resistant strains.

AB Acute kidney injury, often caused by an ischemic insult, is associated with significant short-term morbidity and mortality, and increased risk of chronic kidney disease. The factors affecting the renal response to injury following ischemia and reperfusion remain to be clarified. We found that the Stem cell antigen-1 (Sca-1), commonly used as a stem cell marker, is heavily expressed in renal tubules of the adult mouse kidney. We evaluated its potential role in the kidney using Sca-1 knockout mice submitted to acute ischemia reperfusion injury (IRI), as well as cultured renal proximal tubular cells in which Sca-1 was stably silenced with shRNA. IRI induced more severe injury in Sca-1 null kidneys, as assessed by increased expression of Kim-1 and Ngal, rise in serum creatinine, abnormal pathology, and increased apoptosis of tubular epithelium, and persistent significant renal injury at day 7 post IRI, when recovery of renal function in control animals was nearly complete. Serum creatinine, Kim-1 and Ngal were slightly but significantly elevated even in uninjured Sca-1-/- kidneys. Sca-1 constitutively bound both TGF beta receptors I and II in cultured normal proximal tubular epithelial cells. Its genetic loss or silencing lead to constitutive TGF beta receptor-mediated activation of canonical Smad signaling even in the absence of ligand and to KIM-1 expression in the silenced cells. These studies demonstrate that by normally repressing TGF beta-mediated canonical Smad signaling, Sca-1 plays an important in renal epithelial cell homeostasis and in recovery of renal function following ischemic acute kidney injury.

AB Background
Higher levels of plasma neutrophil gelatinase-associated lipocalin (pNGAL) are an early marker of acute kidney injury and are associated with increased risk of short-term adverse outcomes. The independent association between pNGAL and long-term mortality is unknown.
Methods
In this prospective observational cohort study, we studied 1191 adults who underwent cardiac surgery between 2007 and 2009 at 6 centers in the TRIBE-AKI cohort. We measured the pNGAL on the pre-operative and first 3 post-operative days and assessed the relationship of peri-operative pNGAL concentrations with all-cause mortality.
Results
During a median follow-up of 3.0 years, 139 participants died (50/1000 person-years). Pre-operative levels of pNGAL were associated with 3-year mortality (unadjusted HR 1.96, 95% CI 1.34,2.85) and the association persisted after adjustment for pre-operative variables including estimated glomerular filtration rate (adjusted HR 1.48, 95% CI 1.04-2.12). After adjustment for pre- and intra-operative variables, including pre-operative NGAL levels, the highest tertiles of first post-operative and peak post-operative pNGAL were also independently associated with 3-year mortality risk (adjusted HR 1.31, 95% CI 1.0-1.7 and adjusted HR 1.78, 95% CI 1.2-2.7, respectively). However, after adjustment for peri-operative changes in serum creatinine, there was no longer an independent association between the first post-operative and peak post-operative pNGAL and long-term mortality (adjusted HR 0.98,95% CI 0.79-1.2 for first pNGAL and adjusted HR 1.19, 95% CI 0.87-1.61 for peak pNGAL).
Conclusions
Pre-operative pNGAL levels were independently associated with 3-year mortality after cardiac surgery. While post-operative pNGAL levels were also associated with 3-year mortality, this relationship was not independent of changes in serum creatinine. These findings suggest that while pre-operative pNGAL adds prognostic value for mortality beyond routinely available serum creatinine, post-operative pNGAL measurements may not be as useful for this purpose.

AB Proteolytic processing of amyloid-beta precursor protein (APP) by beta-site APP cleaving enzyme 1 (BACE1) is the initial step in the production of amyloid beta (A beta), which accumulates in senile plaques in Alzheimer's disease (AD). Essential for this cleavage is the transport and sorting of both proteins through endosomal/Golgi compartments. Golgi-localized.-ear-containing ARF-binding (GGA) proteins have striking cargo-sorting functions in these pathways. Recently, GGA1 and GGA3 were shown to interact with BACE1, to be expressed in neurons, and to be decreased in AD brain, whereas little is known about GGA2. Since GGA1 impacts A beta generation by confining APP to the Golgi and perinuclear compartments, we tested whether all GGAs modulate BACE1 and APP transport and processing. We observed decreased levels of secreted APP alpha (sAPP alpha), sAPP beta, and A beta upon GGA overexpression, which could be reverted by knockdown. GGA-BACE1 co-immunoprecipitation was impaired upon GGA-GAE but not VHS domain deletion. Autoinhibition of the GGA1-VHS domain was irrelevant for BACE1 interaction. Our data suggest that all three GGAs affect APP processing via the GGA-GAE domain.

TI Inverted U-Shaped Relationship between Central Venous Pressure and
Intra-Abdominal Pressure in the Early Phase of Severe Acute
Pancreatitis: A Retrospective Study

AB Objective
Many studies have indicated that intra-abdominal pressure (IAP) is positively correlated with central venous pressure (CVP) in severe cases. However, although elevated IAP is common in patients with severe acute pancreatitis (SAP), its relationship with CVP remains unclear. Our study aimed to investigate the association of IAP with CVP in early-phase SAP patients.
Methods
In total, 116 SAP patients were included in this retrospective study. On the first day of hospitalization, blood samples were collected for biochemical examination and cytokine concentration monitoring. Additionally, a urinary catheter and right subclavian vein catheter were inserted for IAP and CVP measurement, respectively. Other routine clinical data were also recorded.
Results
Within 24 hours after hospitalization, CVP fluctuated and increased with increasing IAP up to 15.7 mmHg (P = 0.054) but decreased with increasing IAP when the IAP was > 15.7 mmHg (P < 0.001). After adjusting for abdominal perfusion pressure (APP) and mean arterial pressure (MAP), a similar distribution was observed. An inverted U-shaped trend between IAP and CVP was also present in the groups classified according to the patient's sex, local complications, ascites, and serum amylase levels.
Conclusions
CVP and IAP have an inverted U-shaped relationship, with a peak at an IAP of 15.7 mmHg in the early phase of SAP. After this peak, CVP decreases as IAP increases. These results have crucial implications for clinical fluid resuscitation in SAP patients. In particular, because one CVP value might be correlated with different IAP values in patients with the same CVP, the volume of fluid needed might be different.

AB History has shown that energetic particles can be useful for medical applications. From the time, in 1895 when Roentgen discovered X-rays, and in 1913 when Coolidge developed the vacuum X-ray tube, energetic particles have been an important tool for medicine. Development of the appropriate tool for effective and safe radiotherapy requires an in-depth understanding of the application and constraints. Various solutions are possible and choices must be analyzed on the basis of the suitability for meeting the requirements. Some of the requirements of charged particle therapy are summarized and various accelerator options are described and discussed.

AB Background Genetic variants have been associated with the risk of coronary heart disease. In this study, we tested whether or not a composite of these variants could ascertain the risk of both incident and recurrent coronary heart disease events and identify those individuals who derive greater clinical benefit from statin therapy.
Methods A community-based cohort study (the Malmo Diet and Cancer Study) and four randomised controlled trials of both primary prevention (JUPITER and ASCOT) and secondary prevention (CARE and PROVE IT-TIMI 22) with statin therapy, comprising a total of 48 421 individuals and 3477 events, were included in these analyses. We studied the association of a genetic risk score based on 27 genetic variants with incident or recurrent coronary heart disease, adjusting for traditional clinical risk factors. We then investigated the relative and absolute risk reductions in coronary heart disease events with statin therapy stratified by genetic risk. We combined data from the different studies using a meta-analysis.
Findings When individuals were divided into low (quintile 1), intermediate (quintiles 2-4), and high (quintile 5) genetic risk categories, a significant gradient in risk for incident or recurrent coronary heart disease was shown. Compared with the low genetic risk category, the multivariable-adjusted hazard ratio for coronary heart disease for the intermediate genetic risk category was 1.34 (95% CI 1.22-1.47, p <0.0001) and that for the high genetic risk category was 1.72 (1.55-1.92, p<0.0001). In terms of the benefit of statin therapy in the four randomised trials, we noted a significant gradient (p=0.0277) of increasing relative risk reductions across the low (13%), intermediate (29%), and high (48%) genetic risk categories. Similarly, we noted greater absolute risk reductions in those individuals in higher genetic risk categories (p=0.0101), resulting in a roughly threefold decrease in the number needed to treat to prevent one coronary heart disease event in the primary prevention trials. Specifically, in the primary prevention trials, the number needed to treat to prevent one such event in 10 years was 66 in people at low genetic risk, 42 in those at intermediate genetic risk, and 25 in those at high genetic risk in JUPITER, and 57, 47, and 20, respectively, in ASCOT.
Interpretation A genetic risk score identified individuals at increased risk for both incident and recurrent coronary heart disease events. People with the highest burden of genetic risk derived the largest relative and absolute clinical benefit from statin therapy.

AB Background Warfarin is the most widely used oral anticoagulant worldwide, but serious bleeding complications are common. We tested whether genetic variants can identify patients who are at increased risk of bleeding with warfarin and, consequently, those who would derive a greater safety benefit with a direct oral anticoagulant rather than warfarin.
Methods ENGAGE AF-TIMI 48 was a randomised, double-blind trial in which patients with atrial fibrillation were assigned to warfarin to achieve a target international normalised ratio of 2.0-3.0, or to higher-dose (60 mg) or lower-dose (30 mg) edoxaban once daily. A subgroup of patients was included in a prespecified genetic analysis and genotyped for variants in CYP2C9 and VKORC1. The results were used to create three genotype functional bins (normal, sensitive, and highly sensitive responders to warfarin). This trial is registered with ClinicalTrials.gov, number NCT00781391.
Findings 14 348 patients were included in the genetic analysis. Of 4833 taking warfarin, 2982 (61.7%) were classified as normal responders, 1711 (35.4%) as sensitive responders, and 140 (2.9%) as highly sensitive responders. Compared with normal responders, sensitive and highly sensitive responders spent greater proportions of time over-anticoagulated in the first 90 days of treatment (median 2.2%, IQR 0-20.2; 8.4%, 0-25.8; and 18.3%, 0-32.6; p(trend) <0.0001) and had increased risks of bleeding with warfarin (sensitive responders hazard ratio 1.31, 95% CI 1.05-1.64, p=0.0179; highly sensitive responders 2.66, 1.69-4.19, p<0.0001). Genotype added independent information beyond clinical risk scoring. During the first 90 days, when compared with warfarin, treatment with edoxaban reduced bleeding more so in sensitive and highly sensitive responders than in normal responders (higher-dose edoxaban p(interaction) = 0.0066; lower-dose edoxaban p(interaction) = 0.0036). After 90 days, the reduction in bleeding risk with edoxaban versus warfarin was similarly beneficial across genotypes.
Interpretation CYP2C9 and VKORC1 genotypes identify patients who are more likely to experience early bleeding with warfarin and who derive a greater early safety benefit from edoxaban compared with warfarin.

AB Background New oral anticoagulants for stroke prevention in atrial fibrillation were developed to be given in fixed doses without the need for the routine monitoring that has hindered usage and acceptance of vitamin K antagonists. A concern has emerged, however, that measurement of drug concentration or anticoagulant activity might be needed to prevent excess drug concentrations, which significantly increase bleeding risk. In the ENGAGE AF-TIMI 48 trial, higher-dose and lower-dose edoxaban were compared with warfarin in patients with atrial fibrillation. Each regimen incorporated a 50% dose reduction in patients with clinical features known to increase edoxaban drug exposure. We aim to assess whether adjustment of edoxaban dose in this trial prevented excess drug concentration and the risk of bleeding events.
Methods We analysed data from the randomised, double-blind ENGAGE AF-TIMI 48 trial. We correlated edoxaban dose, plasma concentration, and anti-Factor Xa (FXa) activity and compared efficacy and safety outcomes with warfarin stratified by dose reduction status. Patients with atrial fibrillation and at moderate to high risk of stroke were randomly assigned in a 1: 1: 1 ratio to receive warfarin, dose adjusted to an international normalised ratio of 2.0-3.0, higher-dose edoxaban (60 mg once daily), or lower-dose edoxaban (30 mg once daily). Randomisation was done with use of a central, 24 h, interactive, computerised response system. International normalised ratio was measured using an encrypted point-of-care device. To maintain masking, sham international normalised ratio values were generated for patients assigned to edoxaban. Edoxaban (or placebo-edoxaban in warfarin group) doses were halved at randomisation or during the trial if patients had creatinine clearance 30-50 mL/min, bodyweight 60 kg or less, or concomitant medication with potent P-glycoprotein interaction. Efficacy outcomes included the primary endpoint of all-cause stroke or systemic embolism, ischaemic stroke, and all-cause mortality. Safety outcomes included the primary safety endpoint of major bleeding, fatal bleeding, intracranial haemorrhage, and gastrointestinal bleeding. This trial is registered with ClinicalTrials.gov, number NCT00781391.
Findings Between Nov 19, 2008 and Nov 22, 2010, 21 105 patients were recruited. Patients who met clinical criteria for dose reduction at randomisation (n=5356) had higher rates of stroke, bleeding, and death compared with those who did not have a dose reduction (n=15 749). Edoxaban dose ranged from 15 mg to 60 mg, resulting in a two-fold to three fold gradient of mean trough drug exposure (16.0-48.5 ng/mL in 6780 patients with data available) and mean trough anti-FXa activity (0.35-0.85 IU/mL in 2865 patients). Dose reduction decreased mean exposure by 29% (from 48.5 ng/mL [SD 45.8] to 34.6 ng/mL [30.9]) and 35% (from 24.5 ng/mL [22.7] to 16.0 ng/mL [14.5]) and mean anti-FXa activity by 25% (from 0.85 IU/mL [0.76] to 0.64 IU/mL [0.54]) and 20% (from 0.44 IU/mL [0.37] to 0.35 IU/mL [0.28]) in the higher-dose and lower-dose regimens, respectively. Despite the lower anti-FXa activity, dose reduction preserved the efficacy of edoxaban compared with warfarin (stroke or systemic embolic event: higher dose p(interaction)=0.85, lower dose p(interaction)=0.99) and provided even greater safety (major bleeding: higher dose p(interaction) 0.02, lower dose p(interaction)=0.002).
Interpretation These findings validate the strategy that tailoring of the dose of edoxaban on the basis of clinical factors alone achieves the dual goal of preventing excess drug concentrations and helps to optimise an individual patient's risk of ischaemic and bleeding events and show that the therapeutic window for edoxaban is narrower for major bleeding than thromboembolism.

AB The human virome plays important roles in health and immunity. However, current methods for detecting viral infections and antiviral responses have limited throughput and coverage. Here, we present VirScan, a high-throughput method to comprehensively analyze antiviral antibodies using immunoprecipitation and massively parallel DNA sequencing of a bacteriophage library displaying proteome-wide peptides from all human viruses. We assayed over 108 antibody-peptide interactions in 569 humans across four continents, nearly doubling the number of previously established viral epitopes. We detected antibodies to an average of 10 viral species per person and 84 species in at least two individuals. Although rates of specific virus exposure were heterogeneous across populations, antibody responses targeted strongly conserved "public epitopes" for each virus, suggesting that they may elicit highly similar antibodies. VirScan is a powerful approach for studying interactions between the virome and the immune system.

AB Abnormal accumulation of undigested macromolecules, often disease-specific, is a major feature of lysosomal and neurodegenerative disease and is frequently attributed to defective autophagy. The mechanistic underpinnings of the autophagy defects are the subject of intense research, which is aided by genetic disease models. To gain an improved understanding of the pathways regulating defective autophagy specifically in juvenile neuronal ceroid lipofuscinosis (JNCL or Batten disease), a neurodegenerative disease of childhood, we developed and piloted a GFP-microtubule-associated protein 1 light chain 3 (GFP-LC3) screening assay to identify, in an unbiased fashion, genotype-sensitive small molecule autophagy modifiers, employing a JNCL neuronal cell model bearing the most common disease mutation in CLN3. Thapsigargin, a sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) Ca2+ pump inhibitor, reproducibly displayed significantly more activity in the mouse JNCL cells, an effect that was also observed in human-induced pluripotent stem cell-derived JNCL neural progenitor cells. The mechanism of thapsigargin sensitivity was Ca2+-mediated, and autophagosome accumulation in JNCL cells could be reversed by Ca2+ chelation. Interrogation of intracellular Ca2+ handling highlighted alterations in endoplasmic reticulum, mitochondrial, and lysosomal Ca2+ pools and in store-operated Ca2+ uptake in JNCL cells. These results further support an important role for the CLN3 protein in intracellular Ca2+ handling and in autophagic pathway flux and establish a powerful new platform for therapeutic screening.

AB WTX encodes a tumor suppressor implicated in the pediatric kidney cancer Wilms tumor and in mesenchymal differentiation with potentially distinct functions in the cytoplasm, at the plasma membrane, and in the nucleus. Although modulating components of the WNT signaling pathway is a proposed function for cytoplasmic and membrane-bound WTX, its nuclear properties are not well understood. Here we report that the transcriptional corepressor TRIM28 is the major binding partner for nuclear WTX. WTX interacted with the coiled coil domain of TRIM28 required for its binding to Kruppel-associated box domains of transcription factors and for its chromatin recruitment through its own coiled coil and proline-rich domains. Knockdown of endogenous WTX reduced the recruitment of TRIM28 to a chromatinized reporter sequence and its ability to repress a target transcript. In mouse embryonic stem cells where TRIM28 plays a major role in repressing endogenous retroviruses and long interspersed elements, knockdown of either TRIM28 or WTX combined with single molecule RNA sequencing revealed a highly significant shared set of differentially regulated transcripts, including derepression of non-coding repetitive sequences and their neighboring protein encoding genes (p < 1e - 20). In mesenchymal precursor cells, depletion of WTX and TRIM28 resulted in analogous beta-catenin-independent defects in adipogenic and osteogenic differentiation, and knockdown of WTX reduced TRIM28 binding to Ppar gamma promoter. Together, the physical and functional interaction between WTX and TRIM28 suggests that the nuclear fraction of WTX plays a role in epigenetic silencing, an effect that may contribute to its function as a regulator of cellular differentiation and tumorigenesis.

CARCINOMA; PROTEOLYTIC ACTIVATION; T-ALL; CLEAVAGE; MUTATIONS; DOMAIN;

AB Cell surface receptors of the NOTCH family of proteins are activated by ligand induced intramembrane proteolysis. Unfolding of the extracellular negative regulatory region (NRR), enabling successive proteolysis by the enzymes Adam10 and gamma-secretase, is rate-limiting in NOTCH activation. Mutations in the NOTCH1 NRR are associated with ligand-independent activation and frequently found in human T-cell malignancies. In mammals four NOTCH receptors and five Delta/Jagged ligands exist, but mutations in the NRR are only rarely reported for receptors other than NOTCH1. Using biochemical and functional assays, we compared the molecular mechanisms of ligand-independent signaling in NOTCH1 and the highly related NOTCH2 receptor. Both murine Notch1 and Notch2 require the metalloprotease protease Adam17, but not Adam10 during ligand-independent activation. Interestingly, the human NOTCH2 receptor is resistant to ligand-independent activation compared with its human homologs or murine orthologs. Taken together, our data reveal subtle but functionally important differences for the NRR among NOTCH paralogs and homologs.

AB Estrogen sulfotransferase (EST) regulates estrogen homeostasis by sulfonating and deactivating estrogens. Liver ischemia and reperfusion (I/R) involves both hypoxia during the ischemic phase and oxidative damage during the reperfusion phase. In this report, we showed that the expression of EST was markedly induced by I/R. Mechanistically, oxidative stress-induced activation of Nrf2 was responsible for the EST induction, which was abolished in Nrf2(-/-) mice. EST is a direct transcriptional target of Nrf2. In female mice, the I/R-responsive induction of EST compromised estrogen activity. EST ablation attenuated I/R injury as a result of decreased estrogen deprivation, whereas this benefit was abolished upon ovariectomy. The effect of EST ablation was sex-specific because the EST-/- males showed heightened I/R injury. Reciprocally, both estrogens and EST regulate the expression and activity of Nrf2. Estrogen deprivation by ovariectomy abolished the I/R-responsive Nrf2 accumulation, whereas the compromised estrogen deprivation in EST-/- mice was associated with increased Nrf2 accumulation. Our results suggested a novel I/R-responsive feedback mechanism to limit the activity of Nrf2 in which Nrf2 induces the expression of EST, which subsequently increases estrogen deactivation and limits the estrogen-responsive activation of Nrf2. Inhibition of EST, at least in females, may represent an effective approach to manage hepatic I/R injury.

AB Most cases of congenital obstructive nephropathy are the result of ureteropelvic junction obstructions, and despite their high prevalence, we have a poor understanding of their etiology and scarcity of genetic models. The eight-protein exocyst complex regulates polarized exocytosis of intracellular vesicles in a large variety of cell types. Here we report generation of a conditional knockout mouse for Sec10, a central component of the exocyst, which is the first conditional allele for any exocyst gene. Inactivation of Sec10 in ureteric bud-derived cells using Ksp1.3-Cre mice resulted in severe bilateral hydronephrosis and complete anuria in newborns, with death occurring 6-14 hours after birth. Sec10(FL/FL); Ksp-Cre embryos developed ureteropelvic junction obstructions between E17.5 and E18.5 as a result of degeneration of the urothelium and subsequent overgrowth by surrounding mesenchymal cells. The urothelial cell layer that lines the urinary tract must maintain a hydrophobic luminal barrier again urine while remaining highly stretchable. This barrier is largely established by production of uroplakin proteins that are transported to the apical surface to establish large plaques. By E16.5, Sec10(FL/FL); Ksp-Cre ureter and pelvic urothelium showed decreased uroplakin-3 protein at the luminal surface, and complete absence of uroplakin-3 by E17.5. Affected urothelium at the UPJ showed irregular barriers that exposed the smooth muscle layer to urine, suggesting this may trigger the surrounding mesenchymal cells to overgrow the lumen. Findings from this novel mouse model show Sec10 is critical for the development of the urothelium in ureters, and provides experimental evidence that failure of this urothelial barrier may contribute to human congenital urinary tract obstructions.

AB Oncogenic mutation of the RET receptor tyrosine kinase is observed in several human malignancies. Here, we describe three novel type II RET tyrosine kinase inhibitors (TKI), ALW-II- 41-27, XMD15-44 and HG-6-63-01, that inhibit the cellular activity of oncogenic RET mutants at two digit nanomolar concentration. These three compounds shared a 3-trifluoro-methyl-4-methylpiperazinephenyl pharmacophore that stabilizes the 'DFG-out' inactive conformation of RET activation loop. They blocked RET-mediated signaling and proliferation with an IC50 in the nM range in fibroblasts transformed by the RET/C634R and RET/M918T oncogenes. They also inhibited autophosphorylation of several additional oncogenic RET-derived point mutants and chimeric oncogenes. At a concentration of 10 nM, ALW-II- 41-27, XMD15-44 and HG-6-63-01 inhibited RET kinase and signaling in human thyroid cancer cell lines carrying oncogenic RET alleles; they also inhibited proliferation of cancer, but not non-tumoral Nthy-ori-3-1, thyroid cells, with an IC50 in the nM range. The three compounds were capable of inhibiting the 'gatekeeper' V804M mutant which confers substantial resistance to established RET inhibitors. In conclusion, we have identified a type II TKI scaffold, shared by ALW-II-41-27, XMD15-44 and HG-6-63-01, that may be used as novel lead for the development of novel agents for the treatment of cancers harboring oncogenic activation of RET.

TI Estimating the Impact of Reducing Under-Nutrition on the Tuberculosis
Epidemic in the Central Eastern States of India: A Dynamic Modeling
Study
SO PLOS ONE

AB Background
Tuberculosis (TB) and under-nutrition are widespread in many low and middle-income countries. Momentum to prioritize under-nutrition has been growing at an international level, as demonstrated by the "Scaling Up Nutrition" movement. Low body mass index is an important risk factor for developing TB disease. The objective of this study was to project future trends in TB related outcomes under different scenarios for reducing under-nutrition in the adult population in the Central Eastern states of India.
Methods
A compartmental TB transmission model stratified by body mass index was parameterized using national and regional data from India. We compared TB related mortality and incidence under several scenarios that represented a range of policies and programs designed to reduce the prevalence of under-nutrition, based on the experience and observed trends in similar countries.
Results
The modeled nutrition intervention scenarios brought about reductions in TB incidence and TB related mortality in the Central Eastern Indian states ranging from 43% to 71% and 40% to 68% respectively, relative to the scenario of no nutritional intervention. Modest reductions in under-nutrition averted 4.8 (95% UR 0.5, 17.1) million TB cases and 1.6 (95% UR 0.5, 5.2) million TB related deaths over a period of 20 years of intervention, relative to the scenario of no nutritional intervention. Complete elimination of under-nutrition in the Central Eastern states averted 9.4 (95% UR 1.5, 30.6) million TB cases and 3.2 (95% UR 0.7-, 10.1) million TB related deaths, relative to the scenario of no nutritional intervention.
Conclusion
Our study suggests that intervening on under-nutrition could have a substantial impact on TB incidence and mortality in areas with high prevalence of under-nutrition, even if only small gains in under-nutrition can be achieved. Focusing on under-nutrition may be an effective way to reduce both rates of TB and other diseases associated with under-nutrition.

AB Batrachochytrium dendrobatidis(Bd), a chytrid fungus, has increasingly been implicated as a major factor in the worldwide decline of amphibian populations. The fungus causes chytridiomycosis in susceptible species leading to massive die-offs of adult amphibians. Although Bd infects the keratinized mouthparts of tadpoles and negatively affects foraging behavior, these infections are non-lethal. An important morphogen controlling amphibian metamorphosis is thyroid hormone (T-3). Tadpoles may be infected with Bd and the fungus may be exposed to T-3 during metamorphosis. We hypothesize that exposure of Bd to T-3 may induce the expression of factors associated with host colonization and pathogenicity. We utilized a proteomics approach to better understand the dynamics of the Bd-T-3 interaction. Using liquid chromatography-mass spectrometry (LC-MS), we generated a data set of a large number of cytoplasmic and membrane proteins following exposure of Bd to T-3. From these data, we identified a total of 263 proteins whose expression was significantly changed following T-3 exposure. We provide evidence for expression of an array of proteins that may play key roles in both genomic and non-genomic actions of T-3 in Bd. Additionally, our proteomics study shows an increase in several proteins including proteases and a class of uncommon crinkler and crinkler-like effector proteins suggesting their importance in Bd pathogenicity as well as those involved in metabolism and energy transfer, protein fate, transport and stress responses. This approach provides insights into the mechanistic basis of the Bd-amphibian interaction following T-3 exposure.

AB Background: Multi-component interventions combining educational and environmental strategies have proved effective in increasing children and adolescents' fruit and vegetable intake. However such interventions are complex and difficult to implement and several studies report poor implementation. There is a need for knowledge on the role of dose for behaviour change and for assessment of intervention dose to avoid conclusions that intervention components which are not implemented are ineffective. This study aimed to examine 1) the association between dose of a class curriculum and adolescents' fruit and vegetable intake in a school-based multi-component intervention, 2) if gender and socioeconomic position modify this association.
Methods: We carried out secondary analysis of data from intervention schools in the cluster-randomized Boost study targeting 13-year-olds' fruit and vegetable intake. Teacher-and student data on curriculum dose delivered and received were aggregated to the school-level and class-level (only possible for student data). We analysed the association between curriculum dose and students' (n 995) self-reported fruit and vegetable intake (24-h recall questionnaire) after finalization of the intervention using multi-level analyses. Potential moderation was examined by analyses stratified by gender and socioeconomic position.
Results: Average dose received at class-level was significantly associated with students' fruit and vegetable intake (10 g (CI: 0.06, 20.33) per curricular activity received). In stratified analyses the association remained significant among boys only (14 g (CI: 2.84, 26.76) per curricular activity received). The average dose delivered and received at the school-level was not significantly associated with students' intake.
Conclusions: We found a dose-response relationship between number of curricular activities received and adolescents' fruit and vegetable intake. The results indicate that curriculum dose received only mattered for promotion of fruit and vegetable intake among boys. Future studies should explore this gender difference in larger samples to guide the planning of school-based curricular interventions with regards to the optimal number of curricular activities required to promote behavioural change in subgroups with low fruit and vegetable intake at baseline.

AB Several observations support the hypothesis that differences in synaptic and regional cerebral plasticity between the sexes account for the high ratio of males to females in autism. First, males are more susceptible than females to perturbations in genes involved in synaptic plasticity. Second, sex-related differences in non-autistic brain structure and function are observed in highly variable regions, namely, the heteromodal associative cortices, and overlap with structural particularities and enhanced activity of perceptual associative regions in autistic individuals. Finally, functional cortical reallocations following brain lesions in non-autistic adults (for example, traumatic brain injury, multiple sclerosis) are sex-dependent. Interactions between genetic sex and hormones may therefore result in higher synaptic and consecutively regional plasticity in perceptual brain areas in males than in females. The onset of autism may largely involve mutations altering synaptic plasticity that create a plastic reaction affecting the most variable and sexually dimorphic brain regions. The sex ratio bias in autism may arise because males have a lower threshold than females for the development of this plastic reaction following a genetic or environmental event.

AB Radiomics provides a comprehensive quantification of tumor phenotypes by extracting and mining large number of quantitative image features. To reduce the redundancy and compare the prognostic characteristics of radiomic features across cancer types, we investigated cancer-specific radiomic feature clusters in four independent Lung and Head & Neck (H&N) cancer cohorts (in total 878 patients). Radiomic features were extracted from the pre-treatment computed tomography (CT) images. Consensus clustering resulted in eleven and thirteen stable radiomic feature clusters for Lung and H&N cancer, respectively. These clusters were validated in independent external validation cohorts using rand statistic (Lung RS = 0.92, p < 0.001, H&N RS = 0.92, p < 0.001). Our analysis indicated both common as well as cancer-specific clustering and clinical associations of radiomic features. Strongest associations with clinical parameters: Prognosis Lung CI = 0.60 +/- 0.01, Prognosis H&N CI = 0.68 +/- 0.01; Lung histology AUC = 0.56 +/- 0.03, Lung stage AUC = 0.61 +/- 0.01, H&N HPV AUC = 0.58 +/- 0.03, H&N stage AUC = 0.77 +/- 0.02. Full utilization of these cancer-specific characteristics of image features may further improve radiomic biomarkers, providing a non-invasive way of quantifying and monitoring tumor phenotypic characteristics in clinical practice.

AB Prostate cancer is the second leading cause of cancer death in the United States. Treatment of localized high-risk disease and de nova metastatic disease frequently leads to relapse. These metastatic castration resistant prostate cancers (mCRPC) claim a high mortality rate, despite the extended survival afforded by the growing armamentarium of androgen deprivation, radiation and immunotherapies. Here, we review two studies of neoadjuvant treatment of high-risk localized prostate cancer prior to prostatectomy, the total androgen pathway suppression (TAPS) trial and the neoadjuvant abiraterone acetate (AA) trial. These two trials assessed the efficacy of the non-specific P450c17 inhibitor, ketoconazole and the specific P450c17 inhibitor, AA, to inhibit tissue and serum androgen levels. Furthermore, a novel and validated stable isotope dilution liquid chromatography electrospray ionization selected reaction monitoring mass spectrometry assay was used to accurately quantify adrenal and gonadal androgens in circulation during the course of these trials. The adrenal androgens, Delta(4)-androstene-3,17-dione, dehydroepiandrosterone and dehydroepiandrosterone sulfate were significantly reduced in the patients receiving ketoconazole or AA compared to those who did not. However, in both trials, a significant amount of DHEA-S (similar to 20 mu g/dL) persists and thus may serve as a depot for intratumoral conversion to the potent androgen receptor ligands, testosterone (T) and 5 alpha-dihydrotestosterone (DHT). The final step in conversion of Delta(4)-androstene-3,17-dione and 5 alpha-androstanedione to T and DHT, respectively, is catalyzed by AKRIC3. We therefore present the case that in the context of the DHEA-S depot, P450c17 and AKRIC3 inhibition may be an effective combinatorial treatment strategy. (C) 2014 Elsevier Ireland Ltd.

AB Introduction: Accumulation of insoluble conformationally altered hyperphosphorylated tau occurs as part of the pathogenic process in Alzheimer's disease (AD) and other tauopathies. In most AD subjects, wild-type (WT) tau aggregates and accumulates in neurofibrillary tangles and dystrophic neurites in the brain; however, in some familial tauopathy disorders, mutations in the gene encoding tau cause disease.
Results: We generated a mouse model, Tau4RTg2652, that expresses high levels of normal human tau in neurons resulting in the early stages of tau pathology. In this model, over expression of WT human tau drives pre-tangle pathology in young mice resulting in behavioral deficits. These changes occur at a relatively young age and recapitulate early pre-tangle stages of tau pathology associated with AD and mild cognitive impairment. Several features distinguish the Tau4RTg2652 model of tauopathy from previously described tau transgenic mice. Unlike other mouse models where behavioral and neuropathologic changes are induced by transgenic tau harboring MAPT mutations pathogenic for frontotemporal lobar degeneration (FTLD), the mice described here express the normal tau sequence.
Conclusions: Features of Tau4RTg2652 mice distinguishing them from other established wild type tau overexpressing mice include very early phenotypic manifestations, non-progressive tau pathology, abundant pre-tangle and phosphorylated tau, sparse oligomeric tau species, undetectable fibrillar tau pathology, stability of tau transgene copy number/expression, and normal lifespan. These results suggest that Tau4RTg2652 animals may facilitate studies of tauopathy target engagement where WT tau is driving tauopathy phenotypes.

AB Normalization is an essential step in the analysis of high-throughput data. Multi-sample global normalization methods, such as quantile normalization, have been successfully used to remove technical variation. However, these methods rely on the assumption that observed global changes across samples are due to unwanted technical variability. Applying global normalization methods has the potential to remove biologically driven variation. Currently, it is up to the subject matter experts to determine if the stated assumptions are appropriate. Here, we propose a data-driven alternative. We demonstrate the utility of our method (quantro) through examples and simulations. A software implementation is available from http://www.bioconductor.org/packages/release/bioc/html/quantro.html.

AB Standard stereotaxic reference systems play a key role in human brain studies. Stereotaxic coordinate systems have also been developed for experimental animals including non-human primates, dogs, and rodents. However, they are lacking for other species being relevant in experimental neuroscience including sheep. Here, we present a spatial, unbiased ovine brain template with tissue probability maps (TPM) that offer a detailed stereotaxic reference frame for anatomical features and localization of brain areas, thereby enabling inter-individual and cross-study comparability. Three-dimensional data sets from healthy adult Merino sheep (Ovis orientalis aries, 12 ewes and 26 neutered rams) were acquired on a 1.5 T Philips MRI using a T1w sequence. Data were averaged by linear and non-linear registration algorithms. Moreover, animals were subjected to detailed brain volume analysis including examinations with respect to body weight (BW), age, and sex. The created T1w brain template provides an appropriate population-averaged ovine brain anatomy in a spatial standard coordinate system. Additionally, TPM for gray (GM) and white (WM) matter as well as cerebrospinal fluid (CSF) classification enabled automatic prior-based tissue segmentation using statistical parametric mapping (SPM). Overall, a positive correlation of GM volume and BW explained about 15% of the variance of GM while a positive correlation between WM and age was found. Absolute tissue volume differences were not detected, indeed ewes showed significantly more GM per bodyweight as compared to neutered rams. The created framework including spatial brain template and TPM represent a useful tool for unbiased automatic image preprocessing and morphological characterization in sheep. Therefore, the reported results may serve as a starting point for further experimental and/or translational research aiming at in vivo analysis in this species.

AB Introduction: Breast tumors are comprised of distinct cancer cell populations which differ in their tumorigenic and metastatic capacity. Characterization of cell surface markers enables investigators to distinguish between cancer stem cells and their counterparts. CD24 is a well-known cell surface marker for mammary epithelial cells isolation, recently it was suggested as a potential prognostic marker in a wide variety of malignancies. Here, we demonstrate that CD24(+) cells create intra-tumor heterogeneity, and display highly metastatic properties.
Methods: The mammary carcinoma Mvt1 cells were sorted into CD24(-) and CD24(+) cells. Both subsets were morphologically and phenotypically characterized, and tumorigenic capacity was assessed via orthotopic inoculation of each subset into the mammary fat pad of wild-type and MKR mice. The metastatic capacity of each subset was determined with the tail vein metastasis assay. The role of CD24 in tumorigenesis was further examined with shRNA technology. GFP-labeled cells were monitored in vivo for differentiation. The genetic profile of each subset was analyzed using RNA sequencing.
Results: CD24(+) cells displayed a more spindle-like cytoplasm. The cells formed mammospheres in high efficiency and CD24(+) tumors displayed rapid growth in both WT and MKR mice, and were more metastatic than CD24(-) cells. Interestingly, CD24(-) KD in CD24(+) cells had no effect both in vitro and in vivo on the various parameters studied. Moreover, CD24(+) cells gave rise in vivo to the CD24(-) that comprised the bulk of the tumor. RNA-seq analysis revealed enrichment of genes and pathways of the extracellular matrix in the CD24(+) cells.
Conclusion: CD24(+) cells account for heterogeneity in mammary tumors. CD24 expression at early stages of the cancer process is an indication of a highly invasive tumor. However, CD24 is not a suitable therapeutic target; instead we suggest here new potential targets accounting for early differentiated cancer cells tumorigenic capacity.

AB The site on the HIV-1 gp120 glycoprotein that binds the CD4 receptor is recognized by broadly reactive antibodies, several of which neutralize over 90% of HIV-1 strains. To understand how antibodies achieve such neutralization, we isolated CD4-binding-site (CD4bs) antibodies and analyzed 16 co-crystal structures -8 determined here- of CD4bs antibodies from 14 donors. The 16 antibodies segregated by recognition mode and developmental ontogeny into two types: CDR H3-dominated and V-H-gene-restricted. Both could achieve greater than 80% neutralization breadth, and both could develop in the same donor. Although paratope chemistries differed, all 16 gp120-CD4bs antibody complexes showed geometric similarity, with antibody-neutralization breadth correlating with antibody-angle of approach relative to the most effective antibody of each type. The repertoire for effective recognition of the CD4 supersite thus comprises antibodies with distinct paratopes arrayed about two optimal geometric orientations, one achieved by CDR H3 ontogenies and the other achieved by V-H-gene-restricted ontogenies.

AB Stem cell decline is an important cellular driver of aging-associated pathophysiology in multiple tissues. Epigenetic regulation is central to establishing and maintaining stem cell function, and emerging evidence indicates that epigenetic dysregulation contributes to the altered potential of stem cells during aging. Unlike terminally differentiated cells, the impact of epigenetic dysregulation in stem cells is propagated beyond self; alterations can be heritably transmitted to differentiated progeny, in addition to being perpetuated and amplified within the stem cell pool through self-renewal divisions. This Review focuses on recent studies examining epigenetic regulation of tissue-specific stem cells in homeostasis, aging, and aging-related disease.

AB Background: Carboplatin/paclitaxel (CP), with or without sorafenib, result in objective response rates of 18-20 % in unselected chemotherapy-naive patients. Molecular predictors of survival and response to CP-based chemotherapy in metastatic melanoma (MM) are critical to improving the therapeutic index.
Intergroup trial E2603 randomized MM patients to CP with or without sorafenib. Expression data were collected from pre-treatment formalin-fixed paraffin-embedded (FFPE) tumor tissues from 115 of 823 patients enrolled on E2603. The selected patients were balanced across treatment arms, BRAF status, and clinical outcome. We generated data using Nanostring array (microRNA (miRNA) expression) and DNA-mediated annealing, selection, extension and ligation (DASL)/Illumina microarrays (HT12 v4) (mRNA expression) with protocols optimized for FFPE samples. Integrative computational analysis was performed using a novel Tree-guided Recursive Cluster Selection (T-ReCS) [1] algorithm to select the most informative features/genes, followed by TargetScan miRNA target prediction (Human v6.2) and mirConnX [ 2] for network inference.
Results: T-ReCS identified PLXNB1 as negatively associated with progression-free survival (PFS) and miR-659-3p as the primary miRNA associated positively with PFS. miR-659-3p was differentially expressed based on PFS but not based on treatment arm, BRAF or NRAS status. Dichotomized by median PFS (less vs greater than 4 months), miR-659-3p expression was significantly different. High miR-659-3p expression distinguished patients with responsive disease (complete or partial response) from patients with stable disease. miR-659-3p predicted gene targets include NFIX, which is a transcription factor known to interact with c-Jun and AP-1 in the context of developmental processes and disease.
Conclusions: This novel integrative analysis implicates miR-659-3p as a candidate predictive biomarker for MM patients treated with platinum-based chemotherapy and may serve to improve patient selection.

AB cis-Diamminedichloroplatinum(II) (CDDP), which is mostly referred to as cisplatin, is a widely used antineoplastic. The efficacy of cisplatin can be improved by combining it with the vitamin B6 precursor pyridoxine. Here, we evaluated the putative synergistic interaction of CDDP with pyridoxine in the treatment of an orthotopic mouse model of non-small-cell lung cancer (NSCLC). CDDP and pyridoxine exhibited hyperadditive therapeutic effects. However, this synergy was only observed in the context of an intact immune system and disappeared when the otherwise successful drug combination was applied to the same NSCLC cancer implanted in the lungs of athymic mice (which lack T lymphocytes). Immunocompetent mice that had been cured from NSCLC by the combined regimen of CDDP plus pyridoxine became resistant against subcutaneous rechallenge with the same (but not with an unrelated) cancer cell line. In vitro, CDDP and pyridoxine did not only cause synergistic killing of NSCLC cells but also elicited signs of immunogenic cell death including an endoplasmic reticulum stress response and exposure of calreticulin at the surface of the NSCLC cells. NSCLC cells treated with CDDP plus pyridoxine in vitro elicited a protective anticancer immune response upon their injection into immunocompetent mice. Altogether, these results suggest that the combined regimen of cisplatin plus pyridoxine mediates immune-dependent antineoplastic effects against NSCLC.

AB The BMI1 protein contributes to stem cell pluripotency and oncogenesis via multiple functions, including its newly identified role in DNA damage response (DDR). Although evidence clearly demonstrates that BMI1 facilitates the repair of double-stranded breaks via homologous recombination (HR), it remains unclear how BMI1 regulates checkpoint activation during DDR. We report here that BMI1 has a role in G2/M checkpoint activation in response to etoposide (ETOP) treatment. Ectopic expression of BMI1 in MCF7 breast cancer and DU145 prostate cancer cells significantly reduced ETOP-induced G2/M arrest. Conversely, knockdown of BMI1 in both lines enhanced the arrest. Consistent with ETOP-induced activation of the G2/M checkpoints via the ATM pathway, overexpression and knockdown of BMI1, respectively, reduced and enhanced ETOP-induced phosphorylation of ATM at serine 1981 (ATM pS1981). Furthermore, the phosphorylation of ATM targets, including gamma H2AX, threonine 68 (T68) on CHK2 (CHK2 pT68) and serine 15 (S15) on p53 were decreased in overexpression and increased in knockdown BMI1 cells in response to ETOP. In line with the requirement of NBS1 in ATM activation, we were able to show that BMI1 associates with NBS1 and that this interaction altered the binding of NBS1 with ATM. BMI1 consists of a ring finger (RF), helix-turn-helix-turn-helix-turn (HT), proline/serine (PS) domain and two nuclear localization signals (NLS). Although deletion of either RF or HT did not affect the association of BMI1 with NBS1, the individual deletions of PS and one NLS (KRMK) robustly reduced the interaction. Stable expression of these BMI1 mutants decreased ETOP-induced ATM pS1981 and CHK2 pT68, but not ETOP-elicited gamma H2AX in MCF7 cells. Furthermore, ectopic expression of BMI1 in non-transformed breast epithelial MCF10A cells also compromised ETOP-initiated ATM pS1981 and gamma H2AX. Taken together, we provide compelling evidence that BMI1 decreases ETOP-induced G2/M checkpoint activation via reducing NBS1-mediated ATM activation.

AB Tissue homeostasis is achieved through a balance of cell production (growth) and elimination (regression)(1,2). In contrast to tissue growth, the cells and molecular signals required for tissue regression remain unknown. To investigate physiological tissue regression, we use the mouse hair follicle, which cycles stereotypically between phases of growth and regression while maintaining a pool of stem cells to perpetuate tissue regeneration(3). Here we show by intravital microscopy in live mice(4-6) that the regression phase eliminates the majority of the epithelial cells by two distinct mechanisms: terminal differentiation of suprabasal cells and a spatial gradient of apoptosis of basal cells. Furthermore, we demonstrate that basal epithelial cells collectively act as phagocytes to clear dying epithelial neighbours. Through cellular and genetic ablation we show that epithelial cell death is extrinsically induced through transforming growth factor (TGF)-beta activation and mesenchymal crosstalk. Strikingly, our data show that regression acts to reduce the stem cell pool, as inhibition of regression results in excess basal epithelial cells with regenerative abilities. This study identifies the cellular behaviours and molecular mechanisms of regression that counterbalance growth to maintain tissue homeostasis.

VASCULAR CALCIFICATION
AB Phosphate homeostasis is coordinated and regulated by complex cross-organ talk through delicate hormonal networks. Parathyroid hormone (PTH), secreted in response to low serum calcium, has an important role in maintaining phosphate homeostasis by influencing renal synthesis of 1,25-dihydroxyvitamin D, thereby increasing intestinal phosphate absorption. Moreover, PTH can increase phosphate efflux from bone and contribute to renal phosphate homeostasis through phosphaturic effects. In addition, PTH can induce skeletal synthesis of another potent phosphaturic hormone, fibroblast growth factor 23 (FGF23), which is able to inhibit renal tubular phosphate reabsorption, thereby increasing urinary phosphate excretion. FGF23 can also fine-tune vitamin D homeostasis by suppressing renal expression of 1-alpha hydroxylase (1 alpha(OH)ase). This review briefly discusses how FGF23, by forming a bone-kidney axis, regulates phosphate homeostasis, and how its dysregulation can lead to phosphate toxicity that induces widespread tissue injury. We also provide evidence to explain how phosphate toxicity related to dietary phosphorus overload may facilitate incidence of noncommunicable diseases including kidney disease, cardiovascular disease, cancers and skeletal disorders.

AB Recent studies of political behavior suggest that voting decisions can be influenced substantially by "first-impression" social attributions based on physical appearance. Separate lines of research have implicated the orbitofrontal cortex (OFC) in the judgment of social traits on the one hand and economic decision-making on the other, making this region a plausible candidate for linking social attributions to voting decisions. Here, we asked whether OFC lesions in humans disrupted the ability to judge traits of political candidates or affected how these judgments influenced voting decisions. Seven patients with lateral OFC damage, 18 patients with frontal damage sparing the lateral OFC, and 53 matched healthy participants took part in a simulated election paradigm, in which they voted for real-life (but unknown) candidates based only on photographs of their faces. Consistent with previous work, attributions of "competence" and "attractiveness" based on candidate appearance predicted voting behavior in the healthy control group. Frontal damage did not affect substantially the ability to make competence or attractiveness judgments, but patients with damage to the lateral OFC differed from other groups in how they applied this information when voting. Only attractiveness ratings had any predictive power for voting choices after lateral OFC damage, whereas other frontal patients and healthy controls relied on information about both competence and attractiveness in making their choice. An intact lateral OFC may not be necessary for judgment of social traits based on physical appearance, but it seems to be crucial in applying this information in political decision-making.

AB Myelination of peripheral nerves by Schwann cells requires coordinate regulation of gene repression as well as gene activation. Several chromatin remodeling pathways critical for peripheral nerve myelination have been identified, but the functions of histone methylation in the peripheral nerve have not been elucidated. To determine the role of histone H3 Lys27 methylation, we have generated mice with a Schwann cell-specific knock-out of Eed, which is an essential subunit of the polycomb repressive complex 2 (PRC2) that catalyzes methylation of histone H3 Lys27. Analysis of this mutant revealed no significant effects on early postnatal development of myelin. However, its loss eventually causes progressive hypermyelination of small-diameter axons and apparent fragmentation of Remak bundles. These data identify the PRC2 complex as an epigenomic modulator of mature myelin thickness, which is associated with changes in Akt phosphorylation. Interestingly, we found that Eed inactivation causes derepression of several genes, e.g., Sonic hedgehog (Shh) and Insulin-like growth factor-binding protein 2 (Igfbp2), that become activated after nerve injury, but without activation of a primary regulator of the injury program, c-Jun. Analysis of the activated genes in cultured Schwann cells showed that Igfbp2 regulates Akt activation. Our results identify an epigenomic pathway required for establishing thickness of mature myelin and repressing genes that respond to nerve injury.

AB Intracortical brain-machine interfaces (BMIs) may eventually restore function in those with motor disability after stroke. However, current research into the development of intracortical BMIs has focused on subjects with largely intact cortical structures, such as those with spinal cord injury. Although the stroke perilesional cortex (PLC) has been hypothesized as a potential site for a BMI, it remains unclear whether the injured motor cortical network can support neuroprosthetic control directly. Using chronic electrophysiological recordings in a rat stroke model, we demonstrate here the PLC's capacity for neuroprosthetic control and physiological plasticity. We initially found that the perilesional network demonstrated abnormally increased slow oscillations that also modulated neural firing. Despite these striking abnormalities, neurons in the perilesional network could be modulated volitionally to learn neuroprosthetic control. The rate of learning was surprisingly similar regardless of the electrode distance from the stroke site and was not significantly different from intact animals. Moreover, neurons achieved similar task-related modulation and, as an ensemble, formed cell assemblies with learning. Such control was even achieved in animals with poor motor recovery, suggesting that neuroprosthetic control is possible even in the absence of motor recovery. Interestingly, achieving successful control also reduced locking to abnormal oscillations significantly. Our results thus suggest that, despite the disrupted connectivity in the PLC, it may serve as an effective target for neuroprosthetic control in those with poor motor recovery after stroke.

AB Background
An integrative analysis was conducted to identify genomic alterations at a pathway level that could predict overall survival (OS) in patients with advanced urothelial carcinoma (UC) treated with platinum-based chemotherapy.
Patients and Methods
DNA and RNA were extracted from 103 formalin-fixed paraffin embedded (FFPE) invasive high-grade UC samples and were screened for mutations, copy number variation (CNV) and gene expression analysis. Clinical data were available from 85 cases. Mutations were analyzed by mass-spectrometry based on genotyping platform (Oncomap 3) and genomic imbalances were detected by comparative genomic hybridization (CGH) analysis. Regions with threshold of log2 ratio >= 0.4, or <= 0.6 were defined as either having copy number gain or loss and significantly recurrent CNV across the set of samples were determined using a GISTIC analysis. Expression analysis on selected relevant UC genes was conducted using Nanostring. To define the co-occurrence pattern of mutations and CNV, we grouped genomic events into 5 core signal transduction pathways: 1) TP53 pathway, 2) RTK/RAS/RAF pathway, 3) PI3K/AKT/mTOR pathway, 4) WNT/CTNNB1, 5) RB1 pathway. Cox regression was used to assess pathways abnormalities with survival outcomes.
Results
35 samples (41%) harbored mutations on at least one gene: TP53 (16%), PIK3CA (9%), FGFR3 (2%), HRAS/KRAS (5%), and CTNNB1 (1%). 66% of patients had some sort of CNV. PIK3CA/AKT/mTOR pathway alteration (mutations+CNV) had the greatest impact on OS (p=0.055). At a gene level, overexpression of CTNNB1 (p=0.0008) and PIK3CA (p=0.02) were associated with shorter OS. Mutational status on PIK3CA was not associated with survival. Among other individually found genomic alterations, TP53 mutations (p=0.07), mTOR gain (p=0.07) and PTEN overexpression (p=0.08) have a marginally significant negative impact on OS.
Conclusions
Our study suggests that targeted therapies focusing on the PIK3CA/AKT/mTOR pathway genomic alterations can generate the greatest impact in the overall patient population of high-grade advanced UC.

AB Muscle injury induces a classical inflammatory response in which cells of the innate immune system rapidly invade the tissue. Macrophages are prominently involved in this response and required for proper healing, as they are known to be important for clearing cellular debris and supporting satellite cell differentiation. Here, we sought to assess the role of the adaptive immune system in muscle regeneration after acute damage. We show that T lymphocytes are transiently recruited into the muscle after damage and appear to exert a promyogenic effect on muscle repair. We observed a decrease in the cross-sectional area of regenerating myofibers after injury in Rag2(-/-) gamma-chain(-/-) mice, as compared to WT controls, suggesting that T cell recruitment promotes muscle regeneration. Skeletal muscle infiltrating T lymphocytes were enriched in CD4(+)CD25(+)FOXP3(+) cells. Direct exposure of muscle satellite cells to in vitro induced Treg cells effectively enhanced their expansion, and concurrently inhibited their myogenic differentiation. In vivo, the recruitment of Tregs to acutely injured muscle was limited to the time period of satellite expansion, with possibly important implications for situations in which inflammatory conditions persist, such as muscular dystrophies and inflammatory myopathies. We conclude that the adaptive immune system, in particular T regulatory cells, is critically involved in effective skeletal muscle regeneration. Thus, in addition to their well-established role as regulators of the immune/inflammatory response, T regulatory cells also regulate the activity of skeletal muscle precursor cells, and are instrumental for the proper regeneration of this tissue.

AB Persisters are a subpopulation of normal bacterial cells that show tolerance to conventional antibiotics. Persister cells are responsible for recalcitrant chronic infections and new antibiotics effective against persisters would be a major development in the treatment of these infections. Using the reporter dye SYTOX Green that only stains cells with permeabilized membranes, we developed a fluorescence-based screening assay in a 384-well format for identifying compounds that can kill methicillin-resistant Staphylococcus aureus (MRSA) persisters. The assay proved robust and suitable for high throughput screening (Z -factor: >0.7). In screening a library of hits from a previous screen, which identified compounds that had the ability to block killing of the nematode Caenorhabditis by MRSA, we discovered that the low molecular weight compound NH125, a bacterial histidine kinase inhibitor, kills MRSA persisters by causing cell membrane permeabilization, and that 5 mu g/mL of the compound can kill all cells to the limit of detection in a 10(8) CFU/mL culture of MRSA persisters within 3h. Furthermore, NH125 disrupts 50% of established MRSA biofilms at 20 mu g/mL and completely eradicates biofilms at 160 mu g/mL. Our results suggest that the SYTOX Green screening assay is suitable for large-scale projects to identify small molecules effective against MRSA persisters and should be easily adaptable to a broad range of pathogens that form persisters. Since NH125 has strong bactericidal properties against MRSA persisters and high selectivity to bacteria, we believe NH125 is a good anti-MRSA candidate drug that should be further evaluated.

AB Multiple genetic approaches have identified microRNAs as key effectors in psychiatric disorders as they post-transcriptionally regulate expression of thousands of target genes. However, their role in specific psychiatric diseases remains poorly understood. In addition, epigenetic mechanisms such as DNA methylation, which affect the expression of both microRNAs and coding genes, are critical for our understanding of molecular mechanisms in schizophrenia.
Using clinical, imaging, genetic, and epigenetic data 01 103 patients with schizophrenia and 111 healthy controls of the Mind Clinical Imaging Consortium (MCIC) study of schizophrenia, we conducted gene set enrichment analysis to identity markers for schizophrenia-associated intermediate phenotypes. Genes were ranked based on the correlation between DNA methylation patterns and each phenotype, and then searched for enrichment in 221 predicted microRNA target gene sets.
We found the predicted hsa-miR-219a-5p target gene set to be significantly enriched for genes (ERIIA4, PKNOX1, ESR1, among others) whose methylation status is correlated with hippocampal volume independent of disease status Our results were strengthened by significant associations between hsa-miR-219a-5p target gene methylation patterns and hippocampus-related neuropsychological variables. IPA pathway analysis of the respective predicted hsa-miR-219a-5p target genes revealed associated network functions in behavior and developmental disorders.
Altered methylation patterns of predicted hsa-miR-219a-5p target genes are associated with a structural aberration of the brain that has been proposed as a possible biomarker for schizophrenia. The (dys)regulation of microRNA target genes by epigenetic mechanisms may confer additional risk for developing psychiatric symptoms. Further study is needed to understand possible interactions between microRNAs and epigenetic changes and their impact on risk for brain-based disorders such as schizophrenia. (C) 2015 Elsevier Inc.

AB Major depression and bipolar disorder are associated with decreased bone mineral density (BMD). Antidepressants such as imipramine (IMIP) and specific serotonin reuptake inhibitors (SSRIs) have been implicated in reduced BMD and/or fracture in older depressed patients. Moreover, anticonvulsants such as valproate (VAL) and carbamazepine (CBZ) are also known to increase fracture rates. Although BMD is a predictor of susceptibility to fracture, bone strength is a more sensitive predictor. We measured mechanical and geometrical properties of bone in 68 male Sprague Dawley rats on IMIP, fluoxetine (FLX), VAL, CBZ, CBZ vehicle and saline (SAL), given intraperitoneally daily for 8 weeks. Distinct regions were tested to failure by four-point bending, whereas load displacement was used to determine stiffness. The left femurs were scanned in a MicroCT system to calculate mid-diaphyseal moments of inertia. None of these parameters were affected by antidepressants. However, VAL resulted in a significant decrease in stiffness and a reduction in yield, and CBZ induced a decrease in stiffness. Only CBZ induced alterations in mechanical properties that were accompanied by significant geometrical changes. These data reveal that chronic antidepressant treatment does not reduce bone strength, in contrast to chronic anticonvulsant treatment. Thus, decreased BMD and increased fracture rates in older patients on antidepressants are more likely to represent factors intrinsic to depression that weaken bone rather than antidepressants per se. Patients with affective illness on anticonvulsants may be at particularly high risk for fracture, especially as they grow older, as bone strength falls progressively with age.

AB About 40-60% of patients with late-onset Alzheimer's disease (AD) develop psychosis, which represents a distinct phenotype of more severe cognitive and functional deficits. The estimated heritability of AD+P is similar to 61%, which makes it a good target for genetic mapping. We performed a genome-wide copy-number variation (CNV) study on 496 AD cases with psychosis (AD+P), 639 AD subjects with intermediate psychosis (AD intermediate P) and 156 AD subjects without psychosis (AD - P) who were recruited at the University of Pittsburgh Alzheimer's Disease Research Center using over 1 million single-nucleotide polymorphisms (SNPs) and CNV markers. CNV load analysis found no significant difference in total and average CNV length and CNV number in the AD+P or AD intermediate P groups compared with the AD - P group. Our analysis revealed a marginally significant lower number of duplication events in AD+P cases compared with AD - P controls (P = 0.059) using multivariable regression model. The most interesting finding was the presence of a genome-wide significant duplication in the APC2 gene on chromosome 19, which was protective against developing AD+P (odds ratio = 0.42; P = 7.2E - 10). We also observed suggestive associations of duplications with AD+P in the SET (P = 1.95E - 06), JAG2 (P = 5.01E - 07) and ZFPM1 (P = 2.13E - 07) genes and marginal association of a deletion in CNTLN (P = 8.87E - 04). We have identified potential novel loci for psychosis in Alzheimer's disease that warrant follow-up in large-scale independent studies.

TI Inflammatory and Repair Pathways Induced in Human Bronchoalveolar Lavage

AB Background
Inhalation of ambient levels of ozone causes airway inflammation and epithelial injury.
Methods
To examine the responses of airway cells to ozone-induced oxidative injury, 19 subjects (7 with asthma) were exposed to clean air (0ppb), medium (100ppb), and high (200ppb) ambient levels of ozone for 4h on three separate occasions in a climate-controlled chamber followed by bronchoscopy with bronchoalveolar lavage (BAL) 24h later. BAL cell mRNA expression was examined using Affymetrix GeneChip Microarray. The role of a differentially expressed gene (DEG) in epithelial injury was evaluated in an in vitro model of injury [16HBE14o-cell line scratch assay].
Results
Ozone exposure caused a dose-dependent up-regulation of several biologic pathways involved in inflammation and repair including chemokine and cytokine secretion, activity, and receptor binding; metalloproteinase and endopeptidase activity; adhesion, locomotion, and migration; and cell growth and tumorigenesis regulation. Asthmatic subjects had 1.7- to 3.8-fold higher expression of many DEGs suggestive of increased proinflammatory and matrix degradation and remodeling signals. The most highly up-regulated gene was osteopontin, the protein level of which in BAL fluid increased in a dose-dependent manner after ozone exposure. Asthmatic subjects had a disproportionate increase in non-polymerized osteopontin with increasing exposure to ozone. Treatment with polymeric, but not monomeric, osteopontin enhanced the migration of epithelial cells and wound closure in an alpha 9 beta 1 integrin-dependent manner.
Conclusions
Expression profiling of BAL cells after ozone exposure reveals potential regulatory genes and pathways activated by oxidative stress. One DEG, osteopontin, promotes epithelial wound healing in an in vitro model of injury.

AB The annual suicide rate in South Korea is the highest among the developed countries. Paraquat is a highly lethal herbicide, commonly used in South Korea as a means for suicide. We have studied the effect of the 2011 paraquat prohibition on the national suicide rate and method of suicide in South Korea. We obtained the monthly suicide rate from 2005 to 2013 in South Korea. In our analyses, we adjusted for the effects of celebrity suicides, and economic, meteorological, and seasonal factors on suicide rate. We employed change point analysis to determine the effect of paraquat prohibition on suicide rate over time, and the results were verified by structural change analysis, an alternative statistical method. After the paraquat prohibition period in South Korea, there was a significant reduction in the total suicide rate and suicide rate by poisoning with herbicides or fungicides in all age groups and in both genders. The estimated suicide rates during this period decreased by 10.0% and 46.1% for total suicides and suicides by poisoning of herbicides or fungicides, respectively. In addition, method substitution effect of paraquat prohibition was found in suicide by poisoning by carbon monoxide, which did not exceed the reduction in the suicide rate of poisoning with herbicides or fungicides. In South Korea, paraquat prohibition led to a lower rate of suicide by paraquat poisoning, as well as a reduction in the overall suicide rate. Paraquat prohibition should be considered as a national suicide prevention strategy in developing and developed countries alongside careful observation for method substitution effects.

AB The recent descriptions of widespread random monoallelic expression (RMAE) of genes distributed throughout the autosomal genome indicate that there are more genes subject to RMAE on autosomes than the number of genes on the X chromosome where X-inactivation dictates RMAE of X-linked genes. Several of the autosomal genes that undergo RMAE have independently been implicated in human Mendelian disorders. Thus, parsing the relationship between allele-specific expression of these genes and disease is of interest. Mutations in the human forkhead box P2 gene, FOXP2, cause developmental verbal dyspraxia with profound speech and language deficits. Here, we show that the human FOXP2 gene undergoes RMAE. Studying an individual with developmental verbal dyspraxia, we identify a deletion 3 Mb away from the FOXP2 gene, which impacts FOXP2 gene expression in cis. Together these data suggest the intriguing possibility that RMAE impacts the haploinsufficiency phenotypes observed for FOXP2 mutations.

AB Inference of homology from protein sequences provides an essential tool for analyzing protein structure, function, and evolution. Current sequence-based homology search methods are still unable to detect many similarities evident from protein spatial structures. In computer science a search engine can be improved by considering networks of known relationships within the search database. Here, we apply this idea to protein-sequence-based homology search and show that it dramatically enhances the search accuracy. Our new method, COMPADRE (COmparison of Multiple Protein sequence Alignments using Database RElationships) assesses the relationship between the query sequence and a hit in the database by considering the similarity between the query and hit's known homologs. This approach increases detection quality, boosting the precision rate from 18% to 83% at half-coverage of all database homologs. The increased precision rate allows detection of a large fraction of protein structural relationships, thus providing structure and function predictions for previously uncharacterized proteins. Our results suggest that this general approach is applicable to a wide variety of methods for detection of biological similarities. The web server is available at prodata.swmed.edu/compadre.

AB Galagos are prosimian primates that resemble ancestral primates more than most other extant primates. As in many other mammals, the facial vibrissae of galagos are distributed across the upper and lower jaws and above the eye. In rats and mice, the mystacial macrovibrissae are represented throughout the ascending trigeminal pathways as arrays of cytoarchitecturally distinct modules, with each module having a nearly one-to-one relationship with a specific facial whisker. The macrovibrissal representations are termed barrelettes in the trigeminal somatosensory brainstem, barreloids in the ventroposterior medial subnucleus of the thalamus, and barrels in primary somatosensory cortex. Despite the presence of facial whiskers in all nonhuman primates, barrel-like structures have not been reported in primates. By staining for cytochrome oxidase, Nissl, and vesicular glutamate transporter proteins, we show a distinct array of barrelette-like and barreloid-like modules in the principal sensory nucleus, the spinal trigeminal nucleus, and the ventroposterior medial subnucleus of the galago, Otolemur garnetti. Labeled terminals of primary sensory neurons in the brainstem and cell bodies of thalamocortically projecting neurons demonstrate that barrelette-like and barreloid-like modules are located in areas of these somatosensory nuclei that are topographically consistent with their role in facial touch. Serendipitously, the plane of section that best displays the barreloid-like modules reveals a remarkably distinct homunculus-like patterning which, we believe, is one of the clearest somatotopic maps of an entire body surface yet found.

AB Community composition within the human microbiome varies across individuals, but it remains unknown if this variation is sufficient to uniquely identify individuals within large populations or stable enough to identify them over time. We investigated this by developing a hitting set-based coding algorithm and applying it to the Human Microbiome Project population. Our approach defined body site-specific metagenomic codes: sets of microbial taxa or genes prioritized to uniquely and stably identify individuals. Codes capturing strain variation in clade-specific marker genes were able to distinguish among 100s of individuals at an initial sampling time point. In comparisons with follow-up samples collected 30-300 d later, similar to 30% of individuals could still be uniquely pinpointed using metagenomic codes from a typical body site; coincidental (false positive) matches were rare. Codes based on the gut microbiome were exceptionally stable and pinpointed >80% of individuals. The failure of a code to match its owner at a later time point was largely explained by the loss of specific microbial strains (at current limits of detection) and was only weakly associated with the length of the sampling interval. In addition to highlighting patterns of temporal variation in the ecology of the human microbiome, this work demonstrates the feasibility of microbiome-based identifiability-a result with important ethical implications for microbiome study design. The datasets and code used in this work are available for download from huttenhower.sph.harvard.edu/idability.

AB IMPORTANCE The association between selective serotonin reuptake inhibitor (SSRI) antidepressant use during pregnancy and risk of persistent pulmonary hypertension of the newborn (PPHN) has been controversial since the US Food and Drug Administration issued a public health advisory in 2006.
OBJECTIVE To examine the risk of PPHN associated with exposure to different antidepressant medication classes late in pregnancy.
DESIGN AND SETTING Cohort study nested in the 2000-2010 Medicaid Analytic eXtract for 46 US states and Washington, DC. Last follow-up date was December 31, 2010.
PARTICIPANTS A total of 3 789 330 pregnant women enrolled in Medicaid from 2 months or fewer after the date of last menstrual period through at least 1 month after delivery. The source cohort was restricted to women with a depression diagnosis and logistic regression analysis with propensity score adjustment applied to control for potential confounders.
EXPOSURES FOR OBSERVATIONAL STUDIES SSRI and non-SSRI monotherapy use during the 90 days before delivery vs no use.
MAIN OUTCOMES AND MEASURES Recorded diagnosis of PPHN during the first 30 days after delivery.
RESULTS A total of 128 950 women (3.4%) filled at least 1 prescription for antidepressants late in pregnancy: 102 179 (2.7%) used an SSRI and 26 771 (0.7%) a non-SSRI. Overall, 7630 infants not exposed to antidepressants were diagnosed with PPHN (20.8; 95% CI, 20.4-21.3 per 10 000 births) compared with 322 infants exposed to SSRIs (31.5; 95% CI, 28.3-35.2 per 10 000 births), and 78 infants exposed to non-SSRIs (29.1; 95% CI, 23.3-36.4 per 10 000 births). Associations between antidepressant use and PPHN were attenuated with increasing levels of confounding adjustment. For SSRIs, odds ratios were 1.51 (95% CI, 1.35-1.69) unadjusted and 1.10 (95% CI, 0.94-1.29) after restricting to women with depression and adjusting for the high-dimensional propensity score. For non-SSRIs, the odds ratios were 1.40 (95% CI, 1.12-1.75) and 1.02 (95% CI, 0.77-1.35), respectively. Upon restriction of the outcome to primary PPHN, the adjusted odds ratio for SSRIs was 1.28 (95% CI, 1.01-1.64) and for non-SSRIs 1.14 (95% CI, 0.74-1.74).
CONCLUSIONS AND RELEVANCE Evidence from this large study of publicly insured pregnant women may be consistent with a potential increased risk of PPHN associated with maternal use of SSRIs in late pregnancy. However, the absolute risk was small, and the risk increase appears more modest than suggested in previous studies.

TI Increasing Support for the Treatment of Complicated Grief in Adults of
All Ages
SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION
LA English
DT Editorial Material
ID RANDOMIZED CLINICAL-TRIAL; DISORDER
AB IMPORTANCE Complicated grief (CG) is a debilitating condition, most prevalent in elderly persons. However, to our knowledge, no full-scale randomized clinical trial has studied CG in this population.
OBJECTIVE To determine whether complicated grief treatment (CGT) produces greater improvement in CG and depressive symptoms than grief-focused interpersonal psychotherapy (IPT).
DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial enrolling 151 individuals 50 years or older (mean [SD] age, 66.1 [8.9] years) scoring at least 30 on the Inventory of Complicated Grief (ICG). Participants were recruited from the New York metropolitan area from August 20, 2008, through January 7, 2013, and randomized to receive CGT or IPT. The main outcome was assessed at 20 weeks after baseline, with interim measures collected at 8, 12, and 16 weeks after baseline.
INTERVENTIONS Sixteen sessions of CGT (n = 74) or IPT (n = 77) delivered approximately weekly.
MAIN OUTCOMES AND MEASURES Rate of treatment response, defined as a rating from an independent evaluator of much or very much improved on the Improvement subscale of the Clinical Global Impression Scale.
RESULTS Both treatments produced improvement in CG symptoms. Response rate for CGT (52 individuals [70.5%]) was more than twice that for IPT (24 [32.0%]) (relative risk, 2.20 [95% CI, 1.51-3.22]; P <.001), with the number needed to treat at 2.56. Secondary analyses of CG severity and CG symptom and impairment questionnaire measures confirmed that CGT conferred a significantly greater change in illness severity (22 individuals [35.2%] in the CGT group vs 41 [64.1%] in the IPT group were still at least moderately ill [P =.001]), rate of CG symptom reduction (1.05 ICG points per week for CGT vs 0.75 points per week for IPT [t(633) = 3.85; P <.001]), and the rate of improvement in CG impairment (0.63 work and Social Adjustment Scale points per week with CGT and 0.39 points per week with IPT [t(503) = 2.87; P =.004]). Results were not moderated by participant age.
CONCLUSIONS AND RELEVANCE Complicated grief treatment produced clinically and statistically significantly greater response rates for CG symptoms than a proven efficacious treatment for depression (IPT). Results strongly support the need for physicians and other health care providers to distinguish CG from depression. Given the growing elderly population, the high prevalence of bereavement in aging individuals, and the marked physical and psychological impact of CG, clinicians need to know how to treat CG in older adults.

AB BACKGROUND Most patients with acute coronary syndrome (ACS) are treated with statins, which reduce atherogenic triglyceride-rich lipoproteins. It is uncertain whether triglycerides predict risk after ACS on a background of statin treatment.
OBJECTIVES This study examined the relationship of fasting triglyceride levels to outcomes after ACS in patients treated with statins.
METHODS Long-term and short-term relationships of triglycerides to risk after ACS were examined in the dal-OUTCOMES trial and atorvastatin arm of the MIRACL (Myocardial Ischemia Reduction with Acute Cholesterol Lowering) trial, respectively. Analysis of dal-OUTCOMES included 15,817 patients (97% statin-treated) randomly assigned 4 to 12 weeks after ACS to treatment with dalcetrapib (a cholesteryl ester transfer protein inhibitor) or placebo and followed for a median 31 months. Analysis of MIRACL included 1,501 patients treated with atorvastatin 80 mg daily beginning 1 to 4 days after ACS and followed for 16 weeks. Fasting triglycerides at initial random assignment were related to risk of coronary heart disease death, nonfatal myocardial infarction, stroke, and unstable angina in models adjusted for age, sex, hypertension, smoking, diabetes, high-density lipoprotein cholesterol, and body mass index.
RESULTS Fasting triglyceride levels were associated with both long-term and short-term risk after ACS. In dalOUTCOMES, long-term risk increased across quintiles of baseline triglycerides (p < 0.001). The hazard ratio in the highest/lowest quintile (> 175/<= 80 mg/dl) was 1.50 (95% confidence interval: 1.05 to 2.15). There was no interaction of triglycerides and treatment assignment on the primary outcome. In the atorvastatin group of MIRACL, short-term risk increased across tertiles of baseline triglycerides (p = 0.03), with a hazard ratio of 1.51 (95% confidence interval: 1.05 to 2.15) in highest/lowest tertiles (>195/<= 135 mg/dl). The relationship of triglycerides to risk was independent of lowdensity lipoprotein cholesterol in both studies.
CONCLUSIONS Among patients with ACS treated effectively with statins, fasting triglycerides predict long-term and short-term cardiovascular risk. Triglyceride-rich lipoproteins may be an important additional target for therapy. (C) 2015 by the American College of Cardiology Foundation.

AB To compare the complication rate and effectiveness of mitomycin C (MMC), Ologen alone, and Ologen with 5-fluorouracil (5-FU) as adjunctives with Ex-PRESS mini shunt for medically uncontrolled glaucoma. Retrospective comparative study of 59 Ex-PRESS mini shunt trabeculectomy operations coupled with Ologen implantation alone, transient MMC application or Ologen implantation with 5-FU as adjunctive treatment. Eight eyes (7 patients) received Ologen alone, 37 eyes (34 patients) received MMC, and 14 eyes (14 patients) received Ologen with 5-FU as adjunctive therapy. Baseline characteristics, adjunctive used during operation, along with outcomes including intraocular pressure (IOP), number of anti-hypertensive drops, visual acuity, and complications were documented and compared. The primary outcome was IOP at 12 months. Variables were compared with r x c Fisher tests. The Ologen only group had a significantly higher IOP at 12 months (20.5 +/- A 10.23 mmHg) compared with Ologen combined with 5-FU (12.2 +/- A 1.47 mmHg) or MMC (13.8 +/- A 4.37 mmHg) (p = 0.015, linear mixed model). The Ologen only cohort also had a higher re-operation rate (p = 0.01, Fisher's Exact Test) and higher rate of bleb leak (p = 0.02, Fisher's Exact Test). Visual acuity was similar among all three groups. 5-FU with Ologen is as effective as MMC in maintaining IOP following Ex-PRESS shunt surgery at 1 year. However, Ologen alone may not be as effective as the other two adjunctive agents.

AB Objective: The study examined changes in self-reported attitudes and practices related to suicide risk assessment among providers at emergency departments (EDs) during a three-phase quasi-experimental trial involving implementation of ED protocols for suicidal patients.
Methods: A total of 1,289 of 1,828 (71% response rate) eligible providers at eight EDs completed a voluntary, anonymous survey at baseline, after introduction of universal suicide screening, and after introduction of suicide prevention resources (nurses) and a secondary risk assessment tool (physicians).
Results: Among participants, the median age was 40 years old, 64% were female, and there were no demographic differences across study phases; 68% were nurses, and 32% were attending physicians. Between phase 1 and phase 3, increasing proportions of nurses reported screening for suicide (36% and 95%, respectively, p<. 001) and increasing proportions of physicians reported further assessment of suicide risk (63% and 80%, respectively, p<. 01). Although increasing proportions of providers said universal screening would result in more psychiatric consultations, decreasing proportions said it would slow down clinical care. Increasing proportions of nurses reported often or almost always asking suicidal patients about firearm access (18% 269%, depending on the case), although these numbers remained low relative to ideal practice. Between 35% and 87% of physicians asked about firearms, depending on the case, and these percentages did not change significantly over the study phases.
Conclusions: These findings support the feasibility of implementing universal screening for suicide in EDs, assuming adequate resources, but providers should be educated to ask suicidal patients about firearm access.

AB Dramatic progress in the understanding of underlying disease biology and the development of novel therapeutics has yielded a revolution that is poised to transform the face of lymphoma treatment across a broad spectrum of histologies. Ongoing randomized clinical trials are poised to unseat long-entrenched standards of care in diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma, and Hodgkin lymphoma. Emerging treatment approaches are reviewed, including optimization of existing chemoimmunotherapy platforms, development of chemotherapy-sparing immunotherapy for follicular lymphoma, biologically targeted therapy for subsets of diffuse large B-cell lymphoma, and incorporation of novel agents into the treatment of mantle cell lymphoma and peripheral T-cell lymphoma. Novel therapies in early stage trials with future promise of redefining standards of care are also reviewed for non-Hodgkin and Hodgkin lymphomas, including small molecule pathway inhibitors and advances in immunotherapy.

AB Objective: Service members and veterans underutilize mental health services due to stigma. The study investigated stigma of taking psychiatric medications, and its relationship to internalized stigma of mental illness, gender, age, service era, duration of taking medications, and their perceived helpfulness. Method: Of the 200 veterans completing an anonymous questionnaire in an outpatient mental health waiting room, data are presented on the 159 who reported taking psychiatric medications. Results: Medication stigma was related to internalized stigma and was common: over one half reported feeling uncomfortable disclosing or feeling judged, and about one fifth reported feeling embarrassed. Medication stigma was not related to gender, duration, or helpfulness. Younger age was associated with feeling judged, and more recent service era was associated with shame. Conclusions and Implications for Practice: Medication stigma among veterans is common and warrants further study. Discomfort disclosing and feeling judged might be particularly worthy targets of discussion in shared decisions about medication.

AB Objective: Interventions addressing internalized stigma are a new area of research, and it is important to identify the types of clientele who derive benefit from existing interventions. Method: Information was provided by 235 veterans attending a partial psychiatric hospitalization program, regarding their levels of internalized stigma on admission and discharge from a 3-week program that included interventions targeting internalized stigma. Results: Upon discharge, veterans receiving disability benefits demonstrated less reduction in internalized stigma than those not receiving disability benefits. Time of service moderated the relationship between disability status and change in internalized stigma, such that veterans serving in the more recent Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) cohort who received disability benefits had a more difficult time resolving internalized stigma. Further analyses suggested that OEF/OIF/OND cohort veterans receiving disability benefits have more difficulty developing effective stigma resistance, and more difficulty resolving stigma-related alienation, than other veterans. Conclusions and Implications for Practice: Based on this research, particular attention should be devoted to internalized stigma among OEF/OIF/OND veterans.

AB Background-In this study, we looked at the prognostic value of echocardiographic and hemodynamic measures in a large cohort of patients with precapillary pulmonary hypertension before and after initiation of treatment.
Methods and Results-Data were collected prospectively in a cohort of consecutive patients with precapillary pulmonary hypertension referred between 2002 and 2011. A range of clinical and echocardiographic variables were collected and stored on a database to assess predictors of survival. Invasive hemodynamic data including pulmonary artery pressure, pulmonary vascular resistance, capillary wedge pressure, and cardiac index were also obtained at baseline in all patients. Outcome was defined as mortality because of cardiovascular-related death. The study cohort comprised 777 patients (514 women) with precapillary pulmonary hypertension. A total of 195 (25%) died. In multivariable analysis, moderate or severe tricuspid regurgitation (hazard ratio [HR], 26.537; 95% confidence interval, 11.536-61.044; P< 0.001), right ventricular myocardial performance index (HR, 3.421; 95% confidence interval, 1.777-6.584; P< 0.001), and the presence of pericardial effusion (HR, 1.38; 95% confidence interval, 1.023-1.862; P= 0.035) were independent predictors of mortality. High pulmonary vascular resistance and right atrial pressure by invasive hemodynamic measurements were independent predictors of mortality (HR, 1.084; 95% confidence interval, 1.041-1.130, and 1.079, respectively; 95% confidence interval, 1.049-1.111; P< 0.001 for both), whereas patients with a higher cardiac index had better survival overall (HR, 0.384; 95% confidence interval, 0.307-0.481; P< 0.001).
Conclusions-Right ventricular dysfunction, moderate-severe tricuspid regurgitation, low cardiac index, and raised right atrial pressure were associated with poor survival for both pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertensive disease patients. The severity of tricuspid regurgitation, myocardial performance index, presence of pericardial effusion, pulmonary vascular resistance, cardiac index, and right atrial pressure may be used to stratify risk of death.

AB Background: A high level of evidence exists to suggest that negative attitudes held by clinicians toward persons with sickle cell disease serve as important barriers to the delivery of high quality care to this patient population. Little is known. though. about the characteristics of clinicians that may be predictive of these negative attitudes.
Methods: During spring and summer 2009, we conducted a randomized controlled trial to test an intervenlion to improve clinician attitudes toward persons with sickle cell disease. Participating clinicians completed questionnaires regarding their demographic characteristics and their attitudes toward sic kle cell patienls. Principal clinician charac teristics of interest included their race, professio nal discipline (nurse/ physic ian), and the amount of their recent exposure to sickle cell patients in pain. Secondary analyses from this trial are presented here.
Main Findings: Asian clinicians reported more negative allitudes towards these palients than did Black or White clinicians, nurses reported more negative altitudes lhan physicians. and clinicians w ith the greatest levels of recent exposure to sickle cell patients in pain reported more nega tive attitudes than did clinicians with lower levels of recent exposure.
Conclusions: Our findings could facilitate the development of tailored educational resources needed to improve the quality of care delivered to persons with sickle cell disease, a national priority for sickle cell efforts.

TRAUMA; BATTLEFIELD; RHEOLOGY; EFFICACY
AB Hemorrhage (severe blood loss) from traumatic injury is a leading cause of death for soldiers in combat and for young civilians. In some cases, hemorrhage can be stopped by applying compression of a tourniquet or bandage at the injury site. However, the majority of hemorrhages that prove fatal are "non-compressible", such as those due to an internal injury in the truncal region. Currently, there is no effective way to treat such injuries. In this initial study, we demonstrate that a sprayable polymer-based foam can be effective at treating bleeding from soft tissue without the need for compression. When the foam is sprayed into an open cavity created by injury, it expands and forms a self-supporting barrier that counteracts the expulsion of blood from the cavity. The active material in this foam is the amphiphilic biopolymer, hydrophobically modified chitosan (hmC), which physically connects blood cells into clusters via hydrophobic interactions (the hemostatic mechanism of hmC is thus distinct from the natural clotting cascade, and it works even with heparinized or citrated blood). The amphiphilic nature of hmC also allows it to serve as a stabilizer for the bubbles in the foam. We tested the hmC-based hemostatic foam for its ability to arrest bleeding from an injury to the liver in pigs. Hemostasis was achieved within minutes after application of the hmC foams (without the need for external compression). The total blood loss was 90% lower with the hmC foam relative to controls.

AB Objective: To assess statistical reliability of hospital profiling models in ACS NSQIP (American College of Surgeons' National Surgical Quality Improvement Program).
Background: The ACS NSQIP January 2013 Semiannual Report provided risk-adjusted hospital quality assessments for 137 models.
Methods: Median reliability and percentage of hospitals achieving acceptable reliability were computed for each model. Average median reliability was computed across models with common outcomes.
Results: Median reliability varied across the 137 models, from a high of 0.91 for "All Cases Morbidity" to a low of 0.005 for "Procedure-Targeted Total Hip Arthroplasty Surgical Site Infection." Generally, reliability was greatest for models with larger sample sizes and higher outcome event rates. Among "Essentials" models, 72% attained a median reliability of 0.40 or more, and 24% of 0.70 or more. Among "Procedure-Targeted" models, 29% attained a median reliability of 0.40 or more, and 3% of 0.70 or more. Percentage of hospitals achieving an acceptable reliability of 0.40 ranged from 98% for "All Cases Morbidity" to 0% for "Procedure-Targeted Pancreatectomy Mortality." For Essentials models, average median reliability for each outcome, except mortality, was more than 0.40. However, for Procedure-Targeted models the average median was less than 0.40.
Conclusions: For a large proportion of ACS NSQIP Essentials models, statistical reliability is adequate for assessing surgical quality and differentiating hospital performance. The Procedure-Targeted program is evolving in terms of statistical reliability, with promising results to date. These results also argue for broader discussions of statistical reliability in performance assessments for the profession.

AB The expansion of real-time analytic abilities within current electronic health records has led to innovations in predictive modeling and clinical decision support systems. However, the ability of these systems to influence patient outcomes is currently unknown. Even though nurses are the largest profession within the healthcare workforce, little research has been performed to explore the impact of clinical decision support on their decisions and the patient outcomes associated with them. A scoping literature review explored the impact clinical decision support systems containing healthcare predictive analytics have on four nursing-sensitive patient outcomes (pressure ulcers, failure to rescue, falls, and infections). While many articles discussed variable selection and predictive model development/validation, only four articles examined the impact on patient outcomes. The novelty of predictive analytics and the inherent methodological challenges in studying clinical decision support impact are likely responsible for this paucity of literature. Major methodological challenges include (1) multilevel nature of intervention, (2) treatment fidelity, and (3) adequacy of clinicians' subsequent behavior. There is currently insufficient evidence to demonstrate efficacy of healthcare predictive analytics-enhanced clinical decision support systems on nursing-sensitive patient outcomes. Innovative research methods and a greater emphasis on studying this phenomenon are needed.

AB Background: Geriatric syndromes such as falls, frailty, and functional impairment are multifactorial conditions used to identify vulnerable older adults. Limited data exist on these conditions in older HIV-infected adults, and no studies have comprehensively examined these conditions.
Methods: Geriatric syndromes including falls, urinary incontinence, functional impairment, frailty, sensory impairment, depression, and cognitive impairment were measured in a cross-sectional study of HIV-infected adults aged 50 years and older who had an undetectable viral load on antiretroviral therapy. We examined both HIV and nonHIV- related predictors of geriatric syndromes including sociodemographics, number of comorbidities and nonantiretroviral medications, and HIV-specific variables in multivariate analyses.
Results: We studied 155 participants with a median age of 57 (interquartile range: 54-62) and 94% were men. Prefrailty (56%), difficulty with instrumental activities of daily living (46%), and cognitive impairment (47%) were the most frequent geriatric syndromes. Lower CD4 nadir incidence rate ratio [IRR: 1.16, 95% (confidence interval) CI: 1.06 to 1.26], non-white race (IRR: 1.38, 95% CI: 1.10 to 1.74), and increasing number of comorbidities (IRR: 1.09, 95% CI: 1.03 to 1.15) were associated with increased risk of having more geriatric syndromes.
Conclusions: Geriatric syndromes are common in older HIVinfected adults. Treatment of comorbidities and early initiation of antiretroviral therapy may help to prevent development of these agerelated complications. Clinical care of older HIV-infected adults should consider incorporation of geriatric principles.

AB Background: Increased long-term prescription of opioids and/or benzodiazepines necessitates evaluating risks associated with their receipt. We sought to evaluate the association between long-term opioids and/or benzodiazepines and mortality in HIV-infected patients receiving antiretroviral therapy and uninfected patients.
Methods: Prospective analysis of all-cause mortality using multivariable methods and propensity score matching among HIV-infected patients receiving antiretroviral therapy and uninfected patients.
Results: Of 64,602 available patients (16,989 HIV-infected and 47,613 uninfected), 27,128 (exposed and unexposed to long-term opioids and/or benzodiazepines) were 1: 1 matched by propensity score. The hazard ratio for death was 1.40 [95% confidence interval (CI): 1.22 to 1.61] for long-term opioid receipt, 1.26 (95% CI: 1.08 to 1.48) for long-term benzodiazepine receipt, and 1.56 (95% CI: 1.26 to 1.92) for long-term opioid and benzodiazepine receipt. There was an interaction (P = 0.01) between long-term opioid receipt and HIV status with mortality. For long-term opioid receipt, the hazard ratio was 1.46 (95% CI: 1.15 to 1.87) among HIV-infected patients, and 1.25 (95% CI: 1.05 to 1.49) among uninfected patients. Mortality risk was increased for patients receiving both long-term opioids and benzodiazepines when opioid doses were >= 20 mg morphine-equivalent daily dose and for patients receiving long-term opioids alone when doses were >= 50 mg morphine-equivalent daily dose.
Conclusions: Long-term opioid receipt was associated with an increased risk of death; especially with long-term benzodiazepine receipt, higher opioid doses, and among HIV-infected patients. Long-term benzodiazepine receipt was associated with an increased risk of death regardless of opioid receipt. Strategies to mitigate risks associated with these medications, and caution when they are coprescribed, are needed particularly in HIV-infected populations.

AB Background: Combination antiretroviral therapy (ART) for HIV-1-infected individuals prevents sexual transmission if viral load is suppressed.
Methods: Participants were HIV-1-infected partners randomized to early ART (CD4 350-550) in HPTN052 (n = 886, median follow-up = 2.1 years), a clinical trial of early ART to prevent sexual transmission of HIV-1 in serodiscordant couples at 13 sites in 9 countries. Adherence was assessed through pill count (dichotomized at <95%) and through self-report items. Predictors of adherence were mental health and general health perceptions, substance use, binge drinking, social support, sexual behaviors, and demographics. Viral suppression was defined as HIV plasma viral load <400 copies per milliliter. Adherence counseling and couples' counseling about safer sex were provided. Logistic and linear regression models using generalized estimating equation for repeated measurements were used.
Findings: Through pill count, 82% of participants were adherent at 1 month and 83.3% at 1 year. Mental health was the only psychosocial variable associated with adherence [pill count, odds ratios (OR) = 1.05, 95% confidence intervals (CIs): 1.00 to 1.11; self-report parameter estimate, OR = 0.02, 95% CI: 0.01 to 0.04], although regional differences emerged. Pill count (OR = 1.19, 95% CI: 1.10 to 1.30) and self-report (OR = 1.42, 95% CI: 1.14 to 1.77) adherence were associated with viral suppression.
Interpretation: Although adherence was high among individuals in stable relationships taking ART for prevention, mental health and adherence covaried. Assessing and intervening on mental health inthe context of promoting adherence to ART as prevention should be explored. Adherence and couples' counseling, feedback about viral suppression, and/or altruism may also help explain the magnitude of adherence observed.

AB Inhibition plays many roles in cortical circuits, including coordination of network activity in different brain rhythms and neuronal clusters, gating of activity, gain control, and dictating the manner in which activity flows through the network. This latter is particularly relevant to epileptic states, when extreme hypersynchronous discharges can spread across cortical territories. We review these different physiological and pathological roles and discuss how inhibition can be compromised and why this predisposes the network to seizures.

TI Ebola Virus Disease and Marburg Disease in Pregnancy A Review and
Management Considerations for Filovirus Infection

AB The largest-ever recorded outbreak of viral hemorrhagic fever is ongoing. As a result of the epidemic and rural nature of outbreaks, little is published about the Filovirus infections Ebola virus disease and Marburg disease in pregnancy. This review of viral hemorrhagic fever focusing on Marburg and Ebola uses knowledge of disease in nonpregnant individuals and pregnancy-specific data to inform management for pregnant women. Filovirus infection presentation is similar between pregnant and nonpregnant patients, although infections may be more severe in pregnancy. Although labeled as hemorrhagic fevers, Marburg and Ebola do not commonly cause gross bleeding and should be conceptualized as diseases of high gastrointestinal losses. Early, aggressive supportive care is the mainstay of Filovirus infection management with massive fluid resuscitation as the key management principle. Patients often require 5-10 L or more per day of intravenous or oral fluid to maintain circulating blood volume in the setting of ongoing gastrointestinal loss. Fluid shifts warrant aggressive monitoring and correction of potassium levels and acid-base disturbances to prevent life-threatening arrhythmias and metabolic complications. Regardless of maternal survival, fetal loss rates are nearly 100% in Filovirus infection, likely resulting from unchecked transplacental and hematogenous viral spread. High fetal loss rates support the placenta as a difficult-to-eradicate Filovirus infection reservoir. In conclusion, the management of Filovirus infection in pregnancy should focus on stabilizing the mother with intensive monitoring and aggressive fluid and electrolyte repletion as well as maintaining strict infection control to minimize transmission to others.

TI Variation in Women's Understanding of Prenatal Testing
SO OBSTETRICS AND GYNECOLOGY
LA English
DT Article
ID HEALTH LITERACY; INFORMATION; DIAGNOSIS; BARRIERS; RISK
AB OBJECTIVE: To investigate women's understanding of prenatal testing options and of their own experience with screening, diagnostic genetic testing, or both.
METHODS: This was a secondary analysis of data from a randomized controlled trial of enhanced information and values clarification regarding prenatal genetic testing in the absence of financial barriers to testing. Women in the third trimester of pregnancy were asked whether they had discussed prenatal genetic testing with their health care providers, whether they understood this testing was optional, and whether they had undergone testing during their pregnancy. Multivariable logistic regression models were fit to determine independent predictors of these outcomes.
RESULTS: Data were available from 710 study participants. Discussions about screening tests were reported by 654 participants (92%); only 412 (58%) reported discussing diagnostic testing. That screening and diagnostic testing were optional was evident to approximately two thirds of women (n=470 and 455, respectively). Recall of actual tests undergone was correct for 626 (88%) for screening and for 700 (99%) for diagnostic testing. Racial, ethnic and socioeconomic variation existed in the understanding of whether screening and diagnostic tests were optional and in the correct recall of whether screening had been undertaken in the current pregnancy. In the usual care group, women receiving care in low-income settings were less likely to recall being offered diagnostic testing (adjusted odds ratio 0.23 [0.14-0.39]).
CONCLUSION: Disparities exist in women's recall of prenatal genetic testing discussions and their understanding of their own experience. Interventions that explain testing options to women and help clarify their preferences may help to eliminate these differences.

ID PRIMARY INVASIVE-CARCINOMA; FEMALE GENITAL-TRACT; RADIATION-THERAPY;
CANCER; RHABDOMYOSARCOMA
AB OBJECTIVE: To evaluate the mortality outcomes of vaginal sarcomas in a large cohort compared with vaginal squamous cell and adenocarcinomas.
METHODS: Women with primary invasive vaginal sarcomas, squamous cell carcinomas, and adenocarcinomas diagnosed between 1988 and 2010 were identified within the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Parametric and nonparametric methods were used to compare the demographic and clinical characteristics of women among the three tumor types as well as between sarcoma histologic subtypes. Overall and cancer-specific mortality outcomes were examined using Kaplan-Meier and multivariable Cox proportional hazards models.
RESULTS: The final cohort consisted of 3,121 patients with vaginal squamous cell carcinoma, 720 patients with adenocarcinoma, and 221 patients with sarcoma. Compared with women with squamous cell carcinoma and adenocarcinoma, patients diagnosed with vaginal sarcomas tended to be younger, have larger tumors with less regional extension and lymph node positivity, and be treated primarily with surgery without radiation. In unadjusted analysis, 5-year mortality rates border 30% for all three histologies. After adjusting for other prognostic factors including use of radiation and surgery, patients with vaginal sarcomas had a 69% greater risk of cancer-related mortality compared with patients with squamous cell carcinoma (hazard ratio 1.69, 95% confidence interval 1.26-2.26). Although sarcoma histology failed to associate with mortality risk, age, tumor extension and metastasis, and surgery were poor prognostic factors.
CONCLUSION: Primary vaginal sarcomas are aggressive neoplasms with different presenting characteristics and increased adjusted risk of mortality compared with squamous cell and adenocarcinoma subtypes.

TI Incidence and Effects on Mortality of Venous Thromboembolism in Elderly
Women With Endometrial Cancer
SO OBSTETRICS AND GYNECOLOGY
LA English
DT Article
ID RISK-FACTORS; VALIDATION; CLAIMS
AB OBJECTIVE: To describe the incidence of thromboembolic events (venous thromboembolism) before and after the diagnosis of epithelial endometrial cancer and to evaluate the effects of these events on survival.
METHODS: We used the National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registries linked to Medicare claim files to identify patients with epithelial endometrial cancer diagnosed between 1992 and 2009. To identify venous thromboembolism events 3 months before diagnosis and up to 24 months after diagnosis, we used International Classification of Diseases, 9th Revision, and Healthcare Common Procedure Coding System codes.
RESULTS: A total of 23,122 patients were included; of them 1,873 (8.1%) developed a venous thromboembolism. Patients with low-grade (grades 1 and 2) endometrioid adenocarcinoma had a significantly lower rate of venous thromboembolism 3 months before and 6 months after the diagnosis of cancer (3.6%; 95% confidence interval [CI] 3.3-3.9%) compared with carcinosarcoma (9.2%; 95% CI 7.8-10.8%), clear cell (6.9%; 95% CI 4.8-9.7%), uterine serous cancer (8.1%; 95% CI 7.01-9.3%), and grade 3 endometrioid adenocarcinoma (6.1%; 95% CI 5.4-6.9%) (P<.001). On multivariate analysis during the same time period, most recent time periods of diagnosis, carcinosarcoma histology compared with lower grade endometrial cancer, higher stage, African American race, marital status, chemotherapy delivery, and lymph node dissection were associated with increased risk of venous thromboembolism. The median overall survival for women who experienced a venous thromboembolism 3 months before the diagnosis of endometrial cancer was 31 months (95% CI 20-48 months); in women diagnosed with venous thromboembolism 6 months after the cancer diagnosis was 37 months (95% CI 31-44), and in women who did not experienced a venous thromboembolism was 111 months (95% CI 109-114). After adjusting for prognostic factors, there was an association between venous thromboembolism diagnosed 3 months before endometrial cancer (hazard ratio 1.69, 95% CI 1.34-2.13) or 6 months after the diagnosis (hazard ratio 1.57, 95% CI 1.44-1.71) and lower survival.
CONCLUSION: Patients with uterine serous cancer, carcinosarcoma, clear cell carcinoma, and grade 3 endometrioid adenocarcinoma had a higher rate of venous thromboembolism than patients with low-grade endometrioid adenocarcinoma. A diagnosis of venous thromboembolism was associated with decreased survival in elderly patients with endometrial cancer.

TI A Population-Based, Multifaceted Strategy to Implement Antenatal
Corticosteroid Treatment Versus Standard Care for the Reduction of
Neonatal Mortality Due to Preterm Birth in Low-Income and Middle-Income
Countries: The ACT Cluster Randomized Trial
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB Antenatal corticosteroids are 1 of the most effective hospital-based treatments to reduce neonatal mortality for pregnant women at risk of preterm birth. While studies have shown reductions in neonatal mortality in high-and middle-income countries, and the treatment has been recommended by national and international health organizations, less than 10% of women in low-income countries at risk of preterm birth receive antenatal corticosteroids. This cluster-randomized trial aimed to assess the feasibility, safety, and effectiveness of a multifaceted intervention to increase the use of these treatments in middle-and low-income countries.
Between October 2011 and March 2014, this trial randomly assigned (1: 1) clusters in rural and semiurban areas in Guatemala, Argentina, India, Kenya, Pakistan, and Zambia to this intervention or to standard care. To be eligible, clusters had to have at least 300 births annually in the defined area, either at homes or in facilities. Part of the intervention included better identification of women at risk of preterm birth. In intervention clusters, all health care providers were trained to identify women at risk of preterm birth and to administer dexamethasone in 1 course of four 6-mg doses every 12 hours to at risk women at less than 36 weeks' gestational age. In the intervention arm, women identified as high risk of preterm birth were also referred, but transportation was not provided. All clusters were training in newborn care.
There were 51 intervention clusters with 2520 live births less than the fifth percentile for birth weight and 50 control clusters with 2258 in that percentile. In the intervention cluster, 45% of women received antenatal corticosteroids, whereas 10% of the control group received them (P < 0.0001). Of the less-than-fifth-percentile infants in the intervention group, 28-day neonatal mortality was 225 per 1000 live births, compared with a 323-per-1000-live-births neonatal mortality rate in that percentile in the control group (relative risk (RR), 0.96; 95% confidence interval [CI], 0.87-1.06; P = 0.65). Stillbirths occurred in 229 per 1000 births in the intervention group and 247 per 1000 births in the control group (RR, 0.99; 95% CI, 0.90-1.09; P = 0.81). Including all pregnancies, the neonatal mortality rate for the intervention group was 27.4 per 1000 and 23.9 per 1000 for the control group (RR, 1.12; 95% CI, 1.02-1.22; P = 0.0127), and the stillbirth rate in the intervention group was 26.8 per 1000, and that rate was 24.3 per 1000 in the control group (RR, 1.11; 95% CI, 1.02-1.22; P = 0.0181).
Researchers found that the intervention group was overtreated with antenatal corticosteroids, and even though nearly half of women delivering less-than-fifth-percentile infants received steroids, neonatal mortality did not decrease. Neonatal deaths were significantly increased in the intervention group (3.5 per 1000 live births), as were perinatal deaths (5.1 per 1000 live births) and maternal infection (3%-6% increase). The authors of the study advise caution in implementing interventions such as this one. The findings do not support this strategy, and whether the antenatal corticosteroids directly caused the unfavorable results in the intervention group should be further explored.

TI Goserelin for Ovarian Protection During Breast-Cancer Adjuvant
Chemotherapy
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB Premature ovarian failure is a devastating long-term toxic effect of chemotherapy for premenopausal women. The survival benefit of adjuvant chemotherapy in young women with operable hormone receptor-negative breast cancer is well known, but concern over becoming infertile may influence the choice of treatment for many women. A number of trials have investigated the combined use of a gonadotropin-releasing hormone (GnRH) agonist and adjuvant chemotherapy in an attempt to protect ovarian function in premenopausal women. Results of such studies were mixed, and there were few data on pregnancy outcomes.
The aim of this randomized trial was to determine whether administration of the GnRH agonist goserelin with chemotherapy would reduce the rate of ovarian failure after adjuvant or neoadjuvant treatment of hormone-receptor-negative early-stage breast cancer. A total of 257 premenopausal women with operable hormone receptor-negative breast cancer were randomized to receive standard chemotherapy with goserelin (goserelin group) or standard chemotherapy without goserelin (chemotherapy-alone group). The rate of ovarian failure at 2 years was the primary study end point. Ovarian failure was defined as the absence of menses for the preceding 6 months and follicle-stimulating hormone levels in the postmenopausal range at 2 years. Conditional logistic regression was used to compare rates. Secondary end points evaluated included pregnancy outcomes and disease-free and overall survival.
Of the 257 patients, 218 were eligible and could be evaluated: 113 in the chemotherapy-alone group and 105 in the goserelin group. Complete primary end-point data were available for 135 of the 218 patients who could be evaluated. Among these, the ovarian failure rate was 8% in the goserelin group and 22% in the chemotherapy-alone group; the odds ratio was 0.30, with a 95% confidence interval of 0.09 to 0.97; 2-sided P = 0.04. To determine the effect of the missing primary end-point data on the main study findings, sensitivity analyses were performed. The results of these analyses showed that the missing data had no significant effect on the association between treatment and stratification variables (age and planned chemotherapy regimen). Among the 218 patients who could be evaluated, more women became pregnant in the goserelin group than in the chemotherapy-alone group (21% vs 11%, P = 0.03). Kaplan-Meier curves showed that more women in the goserelin group had improved disease-free survival (P = 0.04) and overall survival (P = 0.05).
Consistent with the findings of previous randomized trials, these data suggest that administration of a GnRH agonist with chemotherapy protects ovarian function, reducing the risk of early menopause and improving prospects for fertility. Although missing primary-end-point data weaken interpretation of the findings, there is no evidence that the missing data influenced the relative comparison between randomized groups.

AB A method to rapidly identify the presence of chronic pain would enhance the care of HIV-infected individuals, but such an instrument has not been assessed in this population to date. We assessed the construct validity of the two-question Brief Chronic Pain Questionnaire (BCPQ) in HIV-infected patients by assessing the association between BCPQ responses and known correlates of chronic pain. Participants in the University of Alabama Center for AIDS Research Network of Integrated Clinical Systems cohort completed the BCPQ, along with the EuroQOL to assess physical function, the PHQ-9 to assess depression, and the PHQ-anxiety module to assess anxiety. Among 100 participants, 25% were female, the mean age was 45 (SD 12), 63% were African American, 27% were publicly insured, the median CD4(+) T cell count was 572 cells/mm(3) (IQR 307-788), and 82% had an undetectable viral load. Participants with chronic pain were more likely to have impaired mobility (43% vs. 12%, p=0.001), difficulty with usual activities (47% vs. 12%, p<0.001), lower overall health state (70 vs. 84, p=0.002), pain today (80% vs. 27%, p<0.001), depression (30% vs. 15%, p=0.10), and anxiety (43% vs. 10%, p<0.001) than those without chronic pain. This study provides preliminary evidence for the BCPQ as a brief questionnaire to identify the presence of chronic pain in HIV care settings.

AB Cutaneous lupus erythematosus (CLE) is an inflammatory disease with a broad range of cutaneous manifestations that may be accompanied by systemic symptoms. The pathogenesis of CLE is complex, multifactorial and incompletely defined. Below we review the current understanding of the cytokines involved in these processes. Ultraviolet (UV) light plays a central role in the pathogenesis of CLE, triggering keratinocyte apoptosis, transport of nucleoprotein autoantigens to the keratinocyte cell surface and the release of inflammatory cytokines (including interferons (IFNs), tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, IL-6, IL-8, IL-10 and IL-17). Increased IFN, particularly type I IFN, is central to the development of CLE lesions. In CLE, type I IFN is produced in response to nuclear antigens, immune complexes and UV light. Type I IFN increases leukocyte recruitment to the skin via inflammatory cytokines, chemokines, and adhesion molecules, thereby inducing a cycle of cutaneous inflammation. Increased TNF alpha in CLE may also cause inflammation. However, decreasing TNF alpha with an anti-TNF alpha agent can induce CLE-like lesions. TNF alpha regulates B cells, increases the production of inflammatory molecules and inhibits the production of IFN-alpha. An increase in the inflammatory cytokines IL-1, IL-6, IL-10, 1L-17 and IL-18 and a decrease in the anti-inflammatory cytokine IL-12 also act to amplify inflammation in CLE. Specific gene mutations may increase the levels of these inflammatory cytokines in some CLE patients. New drugs targeting various aspects of these cytokine pathways are being developed to treat CLE and systemic lupus erythematosus (SLE). Published by Elsevier Ltd.

AB Objective: Aging is associated with reduced neural integrity, yet there are remarkable individual differences in brain health among older adults (OA). One factor that may attenuate age-related neural decline is cardiorespiratory fitness (CRF). The primary aim of this study was to link CRF to neural white matter microstructure using diffusion tensor imaging in OA. Methods: Young adults (YA; n = 32) and OA (n = 27) completed a graded maximal exercise test to evaluate CRF and diffusion tensor magnetic resonance imaging to examine neural white matter integrity. Results: As expected, pervasive age-related declines in white matter integrity were observed when OA were compared to YA. Further, peak VO2 was positively associated with fractional anisotropy (FA), an indicator of white matter integrity, in multiple brain regions in OA, but not YA. In multiple posterior regions such as the splenium, sagittal stratum, posterior corona radiata, and superior parietal white matter, FA values were similar in YA and OA classified as higher fit, with both groups having greater FA than lower fit OA. However, age-related differences in FA values remained in other regions, including the body and genu of the corpus callosum, precuneus, and superior frontal gyrus. Interpretation: CRF is positively associated with neural white matter microstructure in aging. The relationship between peak VO2 and FA appears to be tract-specific, as equivalent FA values were observed in higher fit OA and YA in some white matter tracts, but not others. Further, the association between peak VO2 and FA appears to be age-dependent.

TI Surgical outcomes for perforated peptic ulcer: A prospective case series
at an academic hospital in Monrovia, Liberia
SO AFRICAN JOURNAL OF EMERGENCY MEDICINE
LA English
DT Article
ID HELICOBACTER-PYLORI INFECTION; CARE; PREVALENCE; MORTALITY
AB Introduction: The incidence of perforated peptic ulcer remains high in low and middle-income countries. Mortality can be significant, and early surgical management with careful evaluation of pre-operative risk factors is essential. The purpose of this study was to describe the clinical outcomes of surgical treatment for perforated peptic ulcer disease in Liberia and to explore risk factors for adverse outcomes.
Methods: This study prospectively examined 20 consecutive patients undergoing primary closure with omental patch for perforated pre-pyloric or duodenal peptic ulcer at the John F. Kennedy Medical Centre (JFKMC) in Monrovia, Liberia from May 2009 to March 2010. Pre-operative information was captured in a questionnaire. Risk factors were assessed for univariate and multivariate associations with in-hospital mortality.
Results: Median age was 33 years and 85% were males. A majority of the patients (70%) had a history of gastritis and antacid use. Median time from beginning of symptoms to surgery was 4.5 days. Over-all in-hospital mortality following surgical therapy for perforated peptic ulcer disease was 35%. Median length of stay among survivors was 16 days, and death occurred at median 1 day after admission. Long symptom duration and age >30 years of age were significantly associated with in-hospital mortality on univariate (beta = 2.60 [0.18-5.03], p = 0.035) and multivariate testing (beta = 2.95 [0.02-5.88], p = 0.049).
Conclusion: Peptic ulcer disease and its treatment represent a potentially substantial source of morbidity and mortality in limited-resource settings. In this case series, surgical treatment for perforated peptic ulcer disease carried a high mortality, and the results highlight the potential for public health systems strengthening to prevent poor health outcomes. Peptic ulcer disease in low-and middle-income countries presents unique epidemiology and treatment challenges that may differ significantly from evidence-based guidelines in high-income countries.

AB Almost two decades ago, a number of cell culture and preclinical transplantation studies suggested the striking concept of the tissue-reconstituting ability of hematopoietic stem cells (HSCs). While this heralded an exciting time of radically new therapies for disorders of many organs and tissues, the concept was soon mired by controversy and remained dormant This chapter provides a brief review of evidence for HSC plasticity including our findings based on single HSC transplantation in mouse. These studies strongly support the concept that HSCs are pluripotent and may be the source for the majority, if not all, of the cell types in our body. (C) 2015 Published by Elsevier Ltd.

AB The evolution of post-remission therapy in older adults has for the most part mirrored that for younger adults. However, the suitability of those regimens for an older population is less clear-cut, mainly due to poorer tolerance of therapy and a relatively higher level of disease resistance. Not only is intensive post-remission therapy not appropriate for the majority of older adults, but the role of intensive induction therapy is also unclear. Treatment goals in patients over 55-65 years differ from those in younger patients and may not necessarily be curative but life-prolonging or purely palliative. This paper reviews treatments for older AML patients in an effort to shed some light on choosing appropriate therapy. (C) 2015 Published by Elsevier Ltd.

AB Only 30% of patients in the US who require an allogeneic hematopoietic cell transplant will have a fully HLA matched sibling donor. The National Marrow Donor Program/Be the Match has grown to over 25 million unrelated donors. However, a fully matched unrelated donor may not be available for many patients, particularly for patients of diverse racial and ethnic backgrounds. Over the last 10 years, considerable progress has been made in alternative donor transplant with improvements in outcomes for umbilical cord blood (UCB), haploidentical (haplo) related donor, and mismatched unrelated donor (MMUD) for patients with acute myeloid leukemia. Retrospective studies indicate comparable survival for these three graft sources. In this chapter, we review the latest results for patients receiving alternative donor transplants, and discuss strategies for choosing the optimal donor for each individual patient.

AB Background: Accelerated telomere shortening may cause cancer via chromosomal instability, making it a potentially useful biomarker. However, publications on blood telomere length (BTL) and cancer are inconsistent. We prospectively examined BTL measures over time and cancer incidence.
Methods: We included 792 Normative Aging Study participants with 1-4 BTL measurements from 1999 to 2012. We used linear mixed-effects models to examine BTL attrition by cancer status (relative to increasing age and decreasing years pre-diagnosis), Cox models for time-dependent associations, and logistic regression for cancer incidence stratified by years between BTL measurement and diagnosis.
Findings: Age-related BTL attrition was faster in cancer cases pre-diagnosis than in cancer-free participants (p(difference)=0.017); all participants had similar age-adjusted BTL 8-14 years pre-diagnosis, followed by decelerated attrition in cancer cases resulting in longer BTL three (p=0.003) and four (p=0.012) years pre-diagnosis. Longer time-dependent BTL was associated with prostate cancer (HR = 1.79, p = 0.03), and longer BTL measured <= 4 years pre-diagnosis with any (OR = 3.27, p < 0.001) and prostate cancers (OR = 6.87, p < 0.001).
Interpretation: Age-related BTL attrition was faster in cancer cases but their age-adjusted BTL attrition began decelerating as diagnosis approached. This may explain prior inconsistencies and help develop BTL as a cancer detection biomarker. (C) 2015 The Authors. Published by Elsevier B.V.

AB OBJECTIVES The aim of this study was to investigate prognosis in patients with heart failure (HF) with preserved ejection fraction and the causes of hospitalization and post-hospitalization mortality.
BACKGROUND Although hospitalizations in patients with HF with preserved ejection fraction are common, there are limited data from clinical trials on the causes of admission and the influence of hospitalizations on subsequent mortality risk.
METHODS Patients (n = 4,128) with New York Heart Association functional class II to IV HF and left ventricular ejection fractions >45% were enrolled in I-PRESERVE (Irbesartan in Heart Failure and Preserved Ejection Fraction). A blinded events committee adjudicated cardiovascular hospitalizations and all deaths using predefined and standardized definitions. The risk for death after HF, any-cause, or non-HF hospitalization was assessed using time-dependent Cox proportional hazard models.
RESULTS A total of 2,278 patients had 5,863 hospitalizations during the 49 months of follow-up, of which 3,585 (61%) were recurrent hospitalizations. For any-cause hospitalizations, 26.5% of patients died during follow-up, with an incident mortality rate of 11.1 deaths per 100 patient-years (PYs) and an adjusted hazard ratio of 5.32 (95% confidence interval: 4.21 to 6.23). Overall, 53.6% of hospitalizations were classified as cardiovascular and 43.7% as noncardiovascular, with 2.7% not classifiable. HF was the largest single cause of initial (17.6%) and overall (21.1%) hospitalizations, although, after HF hospitalization, a substantially higher proportion of readmissions were due to primary HF causes (40%). HF hospitalization occurred in 685 patients, with 41% deaths during follow-up, an incident mortality rate of 19.3 deaths per 100 PYs. The adjusted hazard ratio was 2.93 (95% confidence interval: 2.40 to 3.57) relative to patients who were not hospitalized for HF and was greater in those with longer durations of hospitalization. There were 1,593 patients with only non-HF hospitalizations, 21% of whom died during follow-up, with an incident mortality rate of 8.7 deaths per 100 PYs and an adjusted hazard ratio of 4.25 (95% confidence interval: 3.27 to 5.32). The risk for death was highest in the first 30 days and declined over time for all hospitalization categories. Patients not hospitalized for HF or for any cause had observed incident mortality rates of 3.8 and 1.3 deaths per 100 PYs, respectively.
CONCLUSIONS In I-PRESERVE, HFpEF patients hospitalized for any reason, and especially for HF, were at high risk for subsequent death, particularly early. The findings support the need for careful attention in the post-discharge time period including attention to comorbid conditions. Among those hospitalized for HF, the high mortality rate and increased proportion of readmissions due to HF (highest during the first 30 days), suggest that this group would be an appropriate target for investigation of new interventions.

AB OBJECTIVES The objective of this clinical trial was to assess the safety and efficacy of carotid BAT in advanced HF.
BACKGROUND Increased sympathetic and decreased parasympathetic activity contribute to heart failure (HF) symptoms and disease progression. Baroreflex activation therapy (BAT) results in centrally mediated reduction of sympathetic outflow and increased parasympathetic activity.
METHODS Patients with New York Heart Association (NYHA) functional class III HF and ejection fractions <= 35% on chronic stable guideline-directed medical therapy (GDMT) were enrolled at 45 centers in the United States, Canada, and Europe. They were randomly assigned to receive ongoing GDMT alone (control group) or ongoing GDMT plus BAT (treatment group) for 6 months. The primary safety end point was system-and procedure-related major adverse neurological and cardiovascular events. The primary efficacy end points were changes in NYHA functional class, quality-of-life score, and 6-minute hall walk distance.
RESULTS One hundred forty-six patients were randomized, 70 to control and 76 to treatment. The major adverse neurological and cardiovascular event-free rate was 97.2% (lower 95% confidence bound 91.4%). Patients assigned to BAT, compared with control group patients, experienced improvements in the distance walked in 6 min (59.6 +/- 14 m vs. 1.5 +/- 13.2 m; p = 0.004), quality-of-life score (-17.4 +/- 2.8 points vs. 2.1 +/- 3.1 points; p < 0.001), and NYHA functional class ranking (p = 0.002 for change in distribution). BAT significantly reduced N-terminal pro-brain natriuretic peptide (p = 0.02) and was associated with a trend toward fewer days hospitalized for HF (p = 0.08).
CONCLUSIONS BAT is safe and improves functional status, quality of life, exercise capacity, N-terminal pro-brain natriuretic peptide, and possibly the burden of heart failure hospitalizations in patients with GDMT-treated NYHA functional class III HF.

AB Background. End-stage liver disease (ESLD) is an important cause of morbidity among human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients. Quantifying the risk of this outcome over time could help determine which coinfected patients should be targeted for risk factor modification and HCV treatment. We evaluated demographic, clinical, and laboratory variables to predict risk of ESLD in HIV/HCV-coinfected patients receiving antiretroviral therapy (ART).
Methods. We conducted a retrospective cohort study among 6016 HIV/HCV-coinfected patients who received ART within the Veterans Health Administration between 1997 and 2010. The main outcome was incident ESLD, defined by hepatic decompensation, hepatocellular carcinoma, or liver-related death. Cox regression was used to develop prognostic models based on baseline demographic, clinical, and laboratory variables, including FIB-4 and aspartate aminotransferase-to-platelet ratio index, previously validated markers of hepatic fibrosis. Model performance was assessed by discrimination and decision curve analysis.
Results. Among 6016 HIV/HCV patients, 532 (8.8%) developed ESLD over a median of 6.6 years. A model comprising FIB-4 and race had modest discrimination for ESLD (c-statistic, 0.73) and higher net benefit than alternative strategies of treating no or all coinfected patients at relevant risk thresholds. For FIB-4 > 3.25, ESLD risk ranged from 7.9% at 1 year to 26.0% at 5 years among non-blacks and from 2.4% at 1 year to 14.0% at 5 years among blacks.
Conclusions. Race and FIB-4 provided important predictive information on ESLD risk among HIV/HCV patients. Estimating risk of ESLD using these variables could help direct HCV treatment decisions among HIV/HCV-coinfected patients.

AB Background. Children with cerebral malaria (CM) have high rates of mortality and neurologic sequelae. Nitric oxide (NO) metabolite levels in plasma and urine are reduced in CM.
Methods. This randomized trial assessed the efficacy of inhaled NO versus nitrogen (N-2) as an adjunctive treatment for CM patients receiving intravenous artesunate. We hypothesized that patients treated with NO would have a greater increase of the malaria biomarker, plasma angiopoietin-1 (Ang-1) after 48 hours of treatment.
Results. Ninety-two children with CM were randomized to receive either inhaled 80 part per million NO or N-2 for 48 or more hours. Plasma Ang-1 levels increased in both treatment groups, but there was no difference between the groups at 48 hours (P = not significant [NS]). Plasma Ang-2 and cytokine levels (tumor necrosis factor-alpha, interferon-., interleukin [IL]-1 beta, IL-6, IL-10, and monocyte chemoattractant protein-1) decreased between inclusion and 48 hours in both treatment groups, but there was no difference between the groups (P = NS). Nitric oxide metabolite levels-blood methemoglobin and plasma nitrate-increased in patients treated with NO (both P<.05). Seven patients in the N-2 group and 4 patients in the NO group died. Five patients in the N-2 group and 6 in the NO group had neurological sequelae at hospital discharge.
Conclusions. Breathing NO as an adjunctive treatment for CM for a minimum of 48 hours was safe, increased blood methemoglobin and plasma nitrate levels, but did not result in a greater increase of plasma Ang-1 levels at 48 hours.

AB Background. Five neuroinvasive Bacillus cereus infections (4 fatal) occurred in hospitalized patients with acute myelogenous leukemia (AML) during a 9-month period, prompting an investigation by infection control and public health officials.
Methods. Medical records of case-patients were reviewed and a matched case-control study was performed. Infection control practices were observed. Multiple environmental, food, and medication samples common to AML patients were cultured. Multilocus sequence typing was performed for case and environmental B cereus isolates.
Results. All 5 case-patients received chemotherapy and had early-onset neutropenic fevers that resolved with empiric antibiotics. Fever recurred at a median of 17 days (range, 9-20) with headaches and abrupt neurological deterioration. Case-patients had B cereus identified in central nervous system (CNS) samples by (1) polymerase chain reaction or culture or (2) bacilli seen on CNS pathology stains with high-grade B cereus bacteremia. Two case-patients also had colonic ulcers with abundant bacilli on autopsy. No infection control breaches were observed. On case-control analysis, bananas were the only significant exposure shared by all 5 case-patients (odds ratio, 9.3; P =.04). Five environmental or food isolates tested positive for B cereus, including a homogenized banana peel isolate and the shelf of a kitchen cart where bananas were stored. Multilocus sequence typing confirmed that all case and environmental strains were genetically distinct. Multilocus sequence typing-based phylogenetic analysis revealed that the organisms clustered in 2 separate clades.
Conclusions. The investigation of this neuroinvasive B cereus cluster did not identify a single point source but was suggestive of a possible dietary exposure. Our experience underscores the potential virulence of B cereus in immunocompromised hosts.

AB Background. Invasive fusariosis remains an aggressive, albeit infrequent infection in immunocompromised patients.
Methods. We identified all cases of invasive fusariosis between January 2002 and December 2014. We recorded patient characteristics including clinical presentation, treatment, and outcomes at 6 and 12 weeks after diagnosis, as well as species identification and antifungal drug susceptibilities.
Results. Fifteen patients were diagnosed with proven (12, 80%) or probable (3, 20%) fusariosis. Median age was 60 years (range, 26-78), and 10 patients were male. Underlying conditions included hematological malignancies (13, 87%), juvenile idiopathic arthritis (1, 7%), and third-degree burns (1, 7%). Five patients underwent hematopoietic stem-cell transplantation before diagnosis. Six patients (40%) received systemic glucocorticoids, and 11 patients (73%) had prolonged neutropenia at the time of diagnosis. Clinical presentations included the following: skin/ soft tissue infection (8, 53%), febrile neutropenia (4, 27%), respiratory tract infection (2, 13%), and septic arthritis (1, 7%). Twelve patients were treated with voriconazole: 6 (40%) with voriconazole alone, 4 (27%) with voriconazole and terbinafine, and 2 (13%) with voriconazole, terbinafine, and amphotericin. One patient (7%) was treated with terbinafine alone, and another with micafungin alone. Four patients underwent surgical debridement (4, 27%). Susceptibility testing was performed on 9 isolates; 8 demonstrated voriconazole minimum inhibitory concentrations >= 4 mu g/mL. The cumulative probability of survival was 66.7% and 53.3% at 6 and 12 weeks after diagnosis.
Conclusions. Mortality associated with invasive fusariosis remains high. Cumulative mortality at our center was lower than previous reports despite elevated voriconazole minimum inhibitory concentrations. Combination therapy should be studied systematically for fusariosis.

AB Luks, Andrew M., and Erik R. Swenson. Clinician's Corner: Evaluating the risks of high altitude travel in chronic liver disease patients. High Alt Med Biol 16:80-88, 2015.With improvements in the quality of health care, people with chronic medical conditions are experiencing better quality of life and increasingly participating in a wider array of activities, including travel to high altitude. Whenever people with chronic diseases travel to this environment, it is important to consider whether the physiologic responses to hypobaric hypoxia will interact with the underlying medical condition such that the risk of acute altitude illness is increased or the medical condition itself may worsen. This review considers these questions as they pertain to patients with chronic liver disease. While the limited available evidence suggests there is no evidence of liver injury or dysfunction in normal individuals traveling as high as 5000m, there is reason to suspect that two groups of cirrhosis patients are at increased risk for problems, hepatopulmonary syndrome patients, who are at risk for severe hypoxemia following ascent, and portopulmonary hypertension patients who may be at risk for high altitude pulmonary edema and acute right ventricular dysfunction. While liver transplant patients may tolerate high altitude exposure without difficulty, no information is available regarding the risks of long-term residence at altitude with chronic liver disease. All travelers with cirrhosis require careful pre-travel evaluation to identify conditions that might predispose to problems at altitude and develop risk mitigation strategies for these issues. Patients also require detailed counseling about recognition, prevention, and treatment of acute altitude illness and may require different medication regimens to prevent or treat altitude illness than used in healthy individuals.

AB Epidemiological evidence supports the observation that subjects with type 2 diabetes (T2D) are at higher risk to develop Alzheimer's disease (AD). However, whether and how these two conditions are causally linked is unknown. Possible mechanisms include shared genetic risk factors, which were investigated in this study based on recent genome wide association study (GWAS) findings. In order to achieve our goal, we retrieved single nucleotide polymorphisms (SNPs) associated with T2D and AD from large-scale GWAS metaanalysis consortia and tested for overlap among the T2D- and AD-associated SNPs at various p-value thresholds. We then explored the function of the shared T2D/AD GWAS SNPs by leveraging expressional quantitative trait loci, pathways, gene ontology data, and coexpression networks. We found 927 SNPs associated with both AD and T2D with p-value <= 0.01, an overlap significantly larger than random chance (overlapping p-value of 6.93E-28). Among these, 395 of the shared GWAS SNPs have the same risk allele for AD and T2D, suggesting common pathogenic mechanisms underlying the development of both AD and T2D. Genes influenced by shared T2D/AD SNPs with the same risk allele were first identified using a SNP annotation variation (ANNOVAR) software, followed by using Association Protein-Protein Link Evaluator (DAPPLE) software to identify additional proteins that are known to physically interact with the ANNOVAR gene annotations. We found that gene annotations from ANNOVAR and DAPPLE significantly enriched specific KEGG pathways pertaining to immune responses, cell signaling and neuronal plasticity, cellular processes in which abnormalities are known to contribute to both T2D and AD pathogenesis. Thus, our observation suggests that among T2D subjects with common genetic predispositions (e.g., SNPs with consistent risk alleles for T2D and AD), dysregulation of these pathogenic pathways could contribute to the elevated risks for AD in subjects. Interestingly, we found that 532 of the shared T2D/AD GWAS SNPs had divergent risk alleles in the two diseases. For individual shared T2D/AD SNPs with divergent alleles, one of the allelic forms may contribute to one of the diseases (e.g., T2D), but not necessarily to the other (e.g., AD), or vice versa. Collectively, our GWAS studies tentatively support the epidemiological observation of disease concordance between T2D and AD. Moreover, the studies provide the much needed information for the design of future novel therapeutic approaches, for a subpopulation of T2D subjects with genetic disposition to AD, that could benefit T2D and reduce the risk for subsequent development of AD.

AB Background: Voice changes commonly occur from thyroidectomy and may be due to neural or nonneural causes. Such changes can be a source of significant morbidity for any patient, but thyroidectomy in the professional singer carries special significance. We test the hypothesis that the career of singers and professional voice users is not impaired after neural monitored thyroid surgery. Methods: A quantitative analysis of pre- and postoperative neural monitored thyroid surgery voice outcomes utilizing three validated vocal instrumentsVoice Handicap Index (VHI), Singing Voice Handicap Index (SVHI), and Evaluation of Ability to Sing Easily (EASE)in a unique series of professional singers/voice users was performed. Additional quantitative analysis related to final intraoperative electromyography (EMG) amplitude, the time to return to performance, and vocal parameters affected during this interval was performed. Results: Twenty-seven vocal professionals undergoing thyroidectomy were identified, of whom 60% had surgery for thyroid cancer. Pre- and postsurgery flexible fiberoptic laryngeal exams were normal in all patients. Return to performance rate was 100%, and mean time to performance was 2.26 months (1.61). All three vocal instrument mean scores, pre-op vs. post-op, were unchanged: VHI, 4.15 (+/- 5.22) vs. 4.04 (+/- 3.85), p=0.9301; SVHI, 11.26 (+/- 14.41) vs.12.07 (+/- 13.09), p=0.8297; and EASE, 6.19 (+/- 9.19) vs. 6.00 (+/- 7.72), p=0.9348. The vocal parameters most affected from surgery until first performances were vocal fatigue (89%), high range (89%), pitch control and modulation (74%), and strength (81%). Final mean intraoperative EMG amplitude was within normal limits for intraoperative stimulation and had no relationship with time to first professional performance (p=0.7199). Conclusions: Neural monitored thyroidectomy, including for thyroid malignancy, in professional voice users is safe without any changes in three different voice/singing instruments, with 100% return to performance. Intraoperative EMG data at the conclusion of surgery and postoperative laryngeal exam were normal in all patients. Specific vocal parameters are transiently affected during the postoperative recovery phase, which is important to outline in the consent process of this unique patient population and may provide insight into the physiologic state of the larynx subsequent to thyroid surgery.

AB Background: Duration of action increases with repeated administration of neuromuscular-blocking agents, and intraoperative use of high doses of neuromuscular-blocking agent may affect respiratory safety.
Methods: In a hospital-based registry study on 48,499 patients who received intermediate-acting neuromuscular-blocking agents, the authors tested the primary hypothesis that neuromuscular-blocking agents are dose dependently associated with the risk of postoperative respiratory complications. In the secondary analysis, the authors evaluated the association between neostigmine dose given for reversal of neuromuscular-blocking agents and respiratory complications. Post hoc, the authors evaluated the effects of appropriate neostigmine reversal (neostigmine 60 g/kg after recovery of train-of-four count of 2) on respiratory complications. The authors controlled for patient-, anesthesia-, and surgical complexity-related risk factors.
Results: High doses of neuromuscular-blocking agents were associated with an increased risk of postoperative respiratory complications (n = 644) compared with low doses (n = 205) (odds ratio [OR], 1.28; 95% CI, 1.04 to 1.57). Neostigmine was associated with a dose-dependent increase in the risk of postoperative respiratory complications (OR, 1.51; 95% CI, 1.25 to 1.83). Post hoc analysis revealed that appropriate neostigmine reversal eliminated the dose-dependent association between neuromuscular-blocking agents and respiratory complications (for neuromuscular-blocking agent effects with appropriate reversal: OR, 0.98; 95% CI, 0.63 to 1.52).
Conclusions: The use of neuromuscular-blocking agents was dose dependently associated with increased risk of postoperative respiratory complications. Neostigmine reversal was also associated with a dose-dependent increase in the risk of respiratory complications. However, the exploratory data analysis suggests that the proper use of neostigmine guided by neuromuscular transmission monitoring results can help eliminate postoperative respiratory complications associated with the use of neuromuscular-blocking agents.
