AB Little is known regarding the clinical and, in particular, pathological manifestations of patients with isolated colonic Crohn's disease. The purpose of this study was to evaluate the clinical and pathological features of patients with Crohn's disease limited to the colon at initial presentation, and to determine whether there are any histological features that are predictive of outcome after surgery. The clinical features, outcome after surgery, and pathological features of colonic resection specimens of 73 patients who presented initially with isolated colonic Crohn's disease were evaluated and compared with 45 Crohn's disease patients who presented initially with both ileal and colonic involvement. Clinically, patients with isolated colonic Crohn's disease presented at a significantly older age at the time of diagnosis, and had a significantly shorter duration of colitis before surgical resection, than did patients with ileocolonic Crohn's disease at disease onset. Pathologically, patients with isolated colonic Crohn's disease showed a significantly higher proportion of cases with subtotal, total, or left-sided colitis, and significantly fewer strictures/stenosis, pericolonic adhesions, pyloric metaplasia, and cases with proximal worse than distal colonic disease. Overall, patients with isolated colonic Crohn's disease showed a trend toward a lower number of major microscopic Crohn's disease features. A small proportion of patients from both Crohn's disease groups (14% and 13%, respectively) showed inflammatory disease limited to the mucosa, without mural involvement, reminiscent of ulcerative colitis, and these were termed 'ulcerative colitis-like Crohn's disease'. These patients were significantly younger than those with mural involvement. Overall, 44% of patients from both Crohn's disease groups developed at least one adverse outcome, and neither the number nor the type of major Crohn's disease features correlated with adverse outcome. Patients with isolated colonic involvement have distinctive clinical and pathological features. A small subgroup of Crohn's patients shows only mucosal involvement reminiscent of ulcerative colitis.

TI Gap junction inhibition prevents drug-induced liver toxicity and

SO NATURE BIOTECHNOLOGY

ID ACETAMINOPHEN HEPATOTOXICITY; SURVEILLANCE; MECHANISMS
AB Drug-induced liver injury (DILI) limits the development and application of many therapeutic compounds and presents major challenges to the pharmaceutical industry and clinical medicine(1,2). Acetaminophen-containing compounds are among the most frequently prescribed drugs and are also the most common cause of DILI3. Here we describe a pharmacological strategy that targets gap junction communication to prevent amplification of fulminant hepatic failure and acetaminophen-induced hepatotoxicity. We demonstrate that connexin 32 (Cx32), a key hepatic gap junction protein, is an essential mediator of DILI by showing that mice deficient in Cx32 are protected against liver damage, acute inflammation and death caused by liver-toxic drugs. We identify a small-molecule inhibitor of Cx32 that protects against liver failure and death in wild-type mice when co-administered with known hepatotoxic drugs. These findings indicate that gap junction inhibition could provide a pharmaceutical strategy to limit DILI and improve drug safety.

DIFFERENTIATION; DERIVATION; IDENTIFICATION
AB The utility of human pluripotent stem cells is dependent on efficient differentiation protocols that convert these cells into relevant adult cell types. Here we report the robust and efficient differentiation of human pluripotent stem cells into white or brown adipocytes. We found that inducible expression of PPARG2 alone or combined with CEBPB and/or PRDM16 in mesenchymal progenitor cells derived from pluripotent stem cells programmed their development towards a white or brown adipocyte cell fate with efficiencies of 85%-90%. These adipocytes retained their identity independent of transgene expression, could be maintained in culture for several weeks, expressed mature markers and had mature functional properties such as lipid catabolism and insulin-responsiveness. When transplanted into mice, the programmed cells gave rise to ectopic fat pads with the morphological and functional characteristics of white or brown adipose tissue. These results indicate that the cells could be used to faithfully model human disease.

AB The clinicopathological heterogeneity of glioblastoma (GBM) and the various genetic and phenotypic subtypes in GBM stem cells (GSCs) are well described. However, the relationship between GSCs and the corresponding primary tumor from which they were isolated is poorly understood. We have established GSC-enriched neurosphere cultures from 15 newly diagnosed GBM specimens and examined the relationship between the histopathological and genomic features of GSC-derived orthotopic xenografts and those of the respective patient tumors. GSC-initiated xenografts recapitulate the distinctive cytological hallmarks and diverse histological variants associated with the corresponding patient GBM, including giant cell and gemistocytic GBM, and primitive neuroectodermal tumor (PNET)like components. This indicates that GSCs generate tumors that preserve patient-specific disease phenotypes. The majority of GSC-derived intracerebral xenografts (11 of 15) demonstrated a highly invasive behavior crossing the midline, whereas the remainder formed discrete nodular and vascular masses. In some cases, GSC invasiveness correlated with preoperative MRI, but not with the status of PI3-kinase/Akt pathways or O-6-methylguanine methyltransferase expression. Genome-wide screening by array comparative genomic hybridization and fluorescence in situ hybridization revealed that GSCs harbor unique genetic copy number aberrations. GSCs acquiring amplifications of the myc family genes represent only a minority of tumor cells within the original patient tumors. Thus, GSCs are a genetically distinct subpopulation of neoplastic cells within a GBM. These studies highlight the value of GSCs for preclinical modeling of clinically relevant, patient-specific GBM and, thus, pave the way for testing novel anti-GSC/GBM agents for personalized therapy.

AB The nervous system can be significantly affected by cancer. Neurologic symptoms are present in 30% to 50% of oncologic patients presenting to the emergency department or in neurologic consultation at teaching hospitals. Evaluation and treatment require collaborative effort between specialties. The causes of neurologic emergencies in patients with cancer are mostly related to effects of cancer, toxicities of treatments, infections, and paraneoplastic syndromes. These complications cause significant morbidity and mortality and require prompt and accurate diagnostic and treatment measures. This article reviews the common neurologic emergencies affecting patients with cancer and discusses epidemiology, clinical presentation, diagnosis, and treatment modalities.

TI A Novel Approach to Adipocyte Analysis
SO PLASTIC AND RECONSTRUCTIVE SURGERY
LA English
DT Article
ID ADIPOSE CELL SIZE; FAT-GRAFTS; TISSUE; OBESITY; MODEL
AB Background: Fat grafting bench research is difficult because many traditional endpoints cannot be used reliably with adipocytes. Manual cell counting with trypan blue is a common method of measuring cell viability. There are, however, multiple known limitations, including human error, inability to analyze cell size, overestimation of adipocyte viability, and labor intensity. In this study, the authors demonstrate the effectiveness of an improved method of accurate adipocyte analysis using an automated cell counter.
Methods: Human lipoaspirate was obtained, centrifuged, and digested. Samples were analyzed using a hemocytometer and an automated cell counter with two viability dyes. Results were then optimized by novel methods of preparation using carboxymethyl cellulose and formalin.
Results: Manual trypan blue cell counts ranged from 2,750,000 to 19,200,000 live cells/ml. Automated cell counts significantly reduced variability (3,230,000 to 4,290,000 cells/ml). Counting cells between 40 and 150 mu m, which is more specific to adipocytes, yielded 1,040,000 to 1,420,000 viable cells/ml. Using a second viability dye, CellTiter Blue, cell counts ranged between 993,000 and 1,340,000 live cells/ml. Adding carboxymethyl cellulose substantially decreased sampling variability by 80 percent, and the use of formalin prevented the decrease in cell counts over 4 hours from 432,000 to 7,000 cells/ml.
Conclusions: This novel method utilizing automated cell counters can more accurately identify the viable adipocyte population without the limitations of traditional cell counting. In addition, the use of carboxymethyl cellulose and formalin in the preparation process can decrease variability and stabilize cell counts over time. This is an efficient, specific, and reliable method of adipocyte analysis. (Plast. Reconstr. Surg. 129: 380, 2012.)

TI Lentiviral Transduction of Face and Limb Flaps: Implications for

AB Background: Ex vivo introduction of an immunomodulatory transgene into a face or hand allograft may improve the risk-to-benefit ratio of vascularized composite allografts. Abrogation of the immunogenicity of the skin component of a face or hand allograft may decrease alloreactivity and permit the induction of immunologic tolerance. Proof-of-principle demonstrations of transduction of composite tissue have been established using adenoviral vectors, producing transient gene expression. The authors hypothesized that transduction, integration, and long-term expression of transgenes in a vascularized composite allograft could be achieved using lentiviral vectors.
Methods: Ex vivo transduction of heterogeneous primary rat cell lines representative of a composite tissue flap's cellular architecture was performed using a luc-enhanced green fluorescent protein (eGFP) human immunodeficiency virus-1-based lentiviral vector. Ex vivo injections of rat superficial inferior epigastric artery flaps with the viral vector were performed intraarterially, intramuscularly, and intradermally.
Results: Quantifiable reporter expression by flow cytometry (fluorescence-activated cell sorting) analysis and in vitro bioluminescence was observed. The luc-eGFP vector exhibited broad tropism and allowed transgene expression in relevant cell lines and throughout the flaps. Ex vivo intradermal transfection resulted in genomic integration and long-term constitutive gene expression (>150 days). Similarly, efficient intradermal transfection of face and hand flaps in a rat model corroborated this approach. Ex vivo intravascular perfusion of the vector proved inferior to intradermal injection.
Conclusions: Intradermal delivery of the transgenes proved superior to intravascular perfusion. Optimization of this gene-delivery approach may allow long-term, constitutive expression of immunomodulatory proteins in face and hand allografts. Future goals include replacement of the luciferase and eGFP reporter genes with key immunomodulatory proteins. (Plast. Reconstr. Surg. 129: 391, 2012.)

AB Recent technologic advances in cardiac magnetic resonance (MR) imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained acceptance as a standalone imaging modality that can provide further information beyond the capabilities of traditional modalities such as echocardiography and angiography. Black-blood fast spin-echo MR images allow morphologic assessment of the heart with high spatial resolution, while T2-weighted MR images can depict acute myocardial edema. Contrast material-enhanced images can depict and be used to quantify myocardial edema, infiltration, and fibrosis. This review presents recommended cardiac MR protocols for and the spectrum of imaging appearances of the nonischemic cardiomyopathies.

TI When Does a Radiologist's Recommendation for Follow-up Result in
High-Cost Imaging?
SO RADIOLOGY
LA English
DT Article
ID LUNG-CANCER; CT; MANAGEMENT; PROGRESS; SCANS
AB Purpose: To measure the proportion of high-cost imaging generated by a radiologist's recommendation and to identify the imaging findings resulting in follow-up.
Materials and Methods: This retrospective HIPAA-compliant study had institutional review board approval, with waiver of informed consent. A recommended examination was defined as one performed within a single episode of care (defined as fewer than 60 days after the initial imaging) following a radiologist's recommendation in a prior examination report. Chest and abdominal computed tomography (CT), brain and lumbar spine magnetic resonance (MR) imaging, and body positron emission tomography were included for analysis. From a database of all radiology examinations (approximately 200 000) at one institution over a 6-month period, a computerized search identified all high-cost examinations that were preceded by an examination containing a radiologist recommendation. Medical records were reviewed to verify accuracy of the recommending-recommended examination pairs and to determine the reason for the radiologist's recommendation. For proportions, 95% confidence intervals were calculated.
Results: Overall, 1558 of 29 232 (5.3%) high-cost examinations followed a radiologist's recommendation. Chest CT was the high-cost examination most often resulting from a radiologist's recommendation (878 of 9331, 9.4%), followed by abdominal CT (390 of 10 258, 3.8%) and brain MR imaging (222 of 6436, 3.4%). The examination types with the highest numbers of follow-up examinations were chest radiography (n = 431), chest CT (n = 410), abdominal CT (n = 214), and abdominal ultrasonography (n = 120). The most common findings resulting in follow-up were pulmonary nodules or masses (559 of 1558, 35.9%), other pulmonary abnormalities (150 of 1558, 9.6%), adenopathy (103 of 1558, 6.6%), renal lesions (101 of 1558, 6.5%), and negative examination findings (101 of 1558, 6.5%).
Conclusion: Radiologists' recommendations account for only a small proportion of outpatient high-cost imaging examinations. Pulmonary nodule follow-up is the most common cause for radiologist-generated examinations.

AB Purpose: To test whether the relationship between acute ischemic infarct size on concurrent computed tomographic (CT) angiography source images and diffusion-weighted (DW) magnetic resonance images is dependent on the parameters of CT angiography acquisition protocols.
Materials and Methods: This retrospective study had institutional review board approval, and all records were HIPAA compliant. Data in 100 patients with anterior-circulation acute ischemic stroke and large vessel occlusion who underwent concurrent CT angiography and DW imaging within 9 hours of symptom onset were analyzed. Measured areas of hyperintensity at acute DW imaging were used as the standard of reference for infarct size. Information regarding lesion volumes and CT angiography protocol parameters was collected for each patient. For analysis, patients were divided into two groups on the basis of CT angiography protocol differences (patients in group 1 were imaged with the older, slower protocol). Inter-method agreement for infarct size was evaluated by using the Wilcoxon signed rank test, as well as by using Spearman correlation and Bland-Altman analysis. Multivariate analysis was performed to identify predictors of marked (>= 20%) overestimation of infarct size on CT angiography source images.
Results: In group 1 (n = 35), median hypoattenuation volumes on CT angiography source images were slightly underestimated compared with DW imaging hyperintensity volumes (33.0 vs 41.6 mL, P = .01; ratio = 0.83), with high correlation (rho = 0.91). In group 2 (n = 65), median volume on CT angiography source images was much larger than that on DW images (94.8 vs 17.8 mL, P < .0001; ratio = 3.5), with poor correlation (rho = 0.49). This overestimation on CT angiography source images would have inappropriately excluded from reperfusion therapy 44.4% or 90.3% of patients eligible according to DW imaging criteria on the basis of a 100-mL absolute threshold or a 20% or greater mismatch threshold, respectively. Atrial fibrillation and shorter time from contrast material injection to image acquisition were independent predictors of marked (>= 20%) infarct size overestimation on CT angiography source images.
Conclusion: CT angiography protocol changes designed to speed imaging and optimize arterial opacification are associated with significant overestimation of infarct size on CT angiography source images. (C)RSNA, 2011

AB Purpose: To improve clinical three-dimensional (3D) MR spectroscopic imaging with more accurate localization and faster acquisition schemes.
Materials and Methods: Institutional review board approval and patient informed consent were obtained. Data were acquired with a 3-T MR imager and a 32-channel head coil in phantoms, five healthy volunteers, and five patients with glioblastoma. Excitation was performed with localized adiabatic spin-echo refocusing (LASER) by using adiabatic gradient-offset independent adiabaticity wideband uniform rate and smooth truncation (GOIA-W[16,4]) pulses with 3.5-msec duration, 20-kHz bandwidth, 0.81-kHz amplitude, and 45-msec echo time. Interleaved constant-density spirals simultaneously encoded one frequency and two spatial dimensions. Conventional phase encoding (PE) (1-cm(3) voxels) was performed after LASER excitation and was the reference standard. Spectra acquired with spiral encoding at similar and higher spatial resolution and with shorter imaging time were compared with those acquired with PE. Metabolite levels were fitted with software, and Bland-Altman analysis was performed.
Results: Clinical 3D MR spectroscopic images were acquired four times faster with spiral protocols than with the elliptical PE protocol at low spatial resolution (1 cm(3)). Higher-spatial resolution images (0.39 cm(3)) were acquired twice as fast with spiral protocols compared with the low-spatial-resolution elliptical PE protocol. A minimum signal-to-noise ratio (SNR) of 5 was obtained with spiral protocols under these conditions and was considered clinically adequate to reliably distinguish metabolites from noise. The apparent SNR loss was not linear with decreasing voxel sizes because of longer local T2* times. Improvement of spectral line width from 4.8 Hz to 3.5 Hz was observed at high spatial resolution. The Bland-Altman agreement between spiral and PE data is characterized by narrow 95% confidence intervals for their differences (0.12, 0.18 of their means). GOIA-W(16,4) pulses minimize chemical-shift displacement error to 2.1%, reduce nonuniformity of excitation to 5%, and eliminate the need for outer volume suppression.
Conclusion: The proposed adiabatic spiral 3D MR spectroscopic imaging sequence can be performed in a standard clinical MR environment. Improvements in image quality and imaging time could enable more routine acquisition of spectroscopic data than is possible with current pulse sequences. (C)RSNA, 2011

AB Study Design. Consecutive, multicenter retrospective review.
Objective. To evaluate if change in thoracic kyphosis (TK) has a positive or negative impact on spinopelvic alignment after lumbar pedicle subtraction osteotomy (PSO) with short fusions.
Summary of Background Data. In the setting of sagittal malalignment, the effect of large vertebral resections can now be anticipated in long fusions, but their impact on unfused segments (reciprocal changes [RC]) remains poorly understood.
Methods. A total of 34 adult patients (mean age = 54 years; SD = 12) who underwent lumbar PSO with upper instrumented vertebra below T10 were included. Radiographic analysis included pre- and postassessment of TK, lumbar lordosis (LL), sagittal vertical axis (SVA), T1 spinopelvic inclination (T1SPI), pelvic tilt (PT), and pelvic incidence (PI). Final SVA and PT were analyzed to determine successful realignment. RC in the thoracic spine was designated favorable or unfavorable on the basis of impact on final SVA and PT.
Results. Mean PSO resection was 26 degrees. LL increased from 20 degrees to 49 degrees (P < 0.001). SVA improved from 14 to 4 cm (P < 0.001), and PT improved from 33 degrees to 25 degrees (P < 0.001). Mean increase in TK was 13 degrees (P = 0.002) but was unchanged in 11 patients. Five patients had a favorable RC, and 18 patients had an unfavorable RC. Unfavorable RC was attributed to junctional failure in 6 of 18 patients. Significant differences in the unfavorable RC group included age and greater preoperative PT, PI, SVA, and T1SPI.
Conclusion. Significant postoperative alignment changes can occur through unfused thoracic spinal segments after lumbar PSO. Unfavorable RC may limit optimal correction and lead to clinical failures. Risk factors for unfavorable thoracic RC include older patients, larger preoperative PI and PT, and worse preoperative T1SPI and are not simply due to junctional failure. Care should be taken with selective lumbar fusion and PSO in older patients and in those with severe preoperative spinopelvic parameters.

DT Article
ID ENDOSCOPIC THYROIDECTOMY; BREAST APPROACH; RELIABILITY; CATEGORIES;
COSMESIS; NUMBER
AB Background: The Patient Scar Assessment Questionnaire (PSAQ) was constructed to evaluate the effect of any surgical therapy with a linear scar. This study aims to demonstrate reliability and validity of Appearance and Consciousness subscales of PSAQ in patients who underwent thyroidectomy or parathyroidectomy.
Methods: Patients who underwent a thyroidectomy or parathyroidectomy between 2000 and 2010 were administered the aforementioned subscales of the PSAQ. Each subscale was separately evaluated for its psychometric performance according to established criteria. Acceptability, reliability, and internal validity analysis were conducted.
Results: There were 696 patients (mean age = 51.6 years) who participated in this study. Cronbach's alpha acceptable levels were demonstrated for the Appearance (alpha = 0.79) and Consciousness (alpha = 0.85) subscales. Reliability was also supported for the Appearance (Intraclass Correlation Coefficient [ICC] = 0.79) and Consciousness subscales (ICC = 0.81) by performing test-retest reliability analysis. Individual subscale items' correlations with all subscale scores were acceptable for the Appearance (0.31 to 0.78) and Consciousness (0.23 to 0.81) subscales. Internal validity was supported by evaluating correlations between the global assessment item of each subscale and both summary subscale scores (Appearance: 0.42 to 0.72, Consciousness: 0.66 to 0.67).
Conclusions: The Appearance and Consciousness subscales of the PSAQ are both reliable and valid for the assessment of a linear scar following thyroid or parathyroid surgery, independent of the minimally invasive approach being used.

AB A dearth of research to date has explored HIV risk among Black men who report sex with transgender partners. In 2008, 197 Black men residing in Massachusetts were recruited via modified respondent-driven sampling and completed an interviewer-administered survey. Overall, 8% reported sex with a transgender partner in the past 12 months. Over half (56%) reported unprotected sex during their last encounter with transgender partners. Factors significantly associated with having a transgender sex partner: history of substance abuse, incarceration, PTSD symptoms, lower levels of perceived social support, not having been exposed to HIV prevention services in the past 12 months, and endorsement of mobile van services as a comfortable location to access health care. These formative data suggest that Black men who partner with transgender individuals may be at elevated risk for an array of poorer health-related outcomes, including HIV sexual risk, substance abuse, incarceration, psychosocial vulnerability, and lack of access to health care. Theory-driven interventions that consider the broader context affecting the embodiment of HIV risk are warranted for men who have sex with transgender partners.

AB There has been little research on the causes of hospitalization when patients are first diagnosed with HIV in the hospital. Reduced access to care could partially explain inpatient diagnosis. We sought to determine if the patients diagnosed as inpatients are hospitalized due to a HIV-related cause versus some other causes, to compare access to care of patients diagnosed with HIV in hospital and outpatient settings, and to determine factors associated with access to care. Participants were newly diagnosed with HIV and recruited between January 2006 and August 2007. The reason for hospitalization was classified as HIV-related, other infectious cause, noninfectious cause, or miscellaneous cause. Access to care was self-reported using a six-item scale and scores were compared with the t test. Multivariate linear regression determined factors associated with improved access to care. Of 185 participants in the study, 78 were diagnosed in hospital and 107 in outpatient settings. Thirty-two percent of participants were female, 90% were racial/ethnic minority, 45% had no high school diploma, and 85% were uninsured. HIV-related conditions accounted for 60% of admissions, followed by non-infectious causes (20%) and other infectious causes (17%). Inpatients did not report less access to care than patients diagnosed while outpatients. Multivariate analysis demonstrated improvement in access to care with better health insurance (p = 0.01) and greater education (p = 0.08). HIV-related preventable conditions account for many hospitalizations when patients are first diagnosed with HIV. While socioeconomic factors are associated with perceived access to care, persons diagnosed in the inpatient setting do not report lower perceived access to care than persons diagnosed as outpatients, suggesting other barriers to earlier diagnosis.

CREATININE; SURVIVAL; BLOCKER
AB Early in the course of ST-segment elevation myocardial infarction (STEMI), therapies that may harm patients who develop left ventricular (LV) dysfunction, such as beta-blockers, are often administered. The investigators analyzed the ACTIVATE-SF database, a registry of consecutive STEMI activations presenting to 2 medical centers at the University of California, San Francisco. LV dysfunction was defined as an ejection fraction <= 40% on echocardiography. Of 211 patients included in the analysis, 66 (31%) had LV ejection fractions <= 40%. Patients with LV dysfunction were older (63 +/- 15 vs 56 +/- 13 years, p = 0.002). In multivariate regression models, decreased renal function (reference group, creatinine <1.0 mg/di; adjusted odds ratio [AOR] creatinine >1.5 mg/di 6.35, 95% confidence interval [CI] 1.66 to 24.31, p = 0.007), a history of coronary artery disease (AOR 3.12, 95% CI 1.26 to 7.71, p = 0.014), ST-segment elevation >2 mm on 12-lead electrocardiography (AOR 2.78, 95% CI 1.31 to 5.87, p = 0.008), and need for mechanical ventilation (AOR 3.98, 95% CI 1.41 to 11.19, p = 0.009) increased the odds of LV dysfunction. Inferior ST-segment elevations were associated with 88% decreased odds of LV dysfunction (AOR 0.12, 95% CI 0.06 to 0.35, p <0.001). A prediction score using these characteristics stratified patients into low-, intermediate-, and high-risk groups for LV dysfunction; positive likelihood ratios for LV dysfunction in these groups were 0.07, 1.14, and 4.93, respectively. In conclusion, 5 key predictors of in-hospital LV dysfunction after STEMI were identified; a risk score based on these predictors helps to quickly identify patients presenting with STEW who are at the highest risk for developing significant LV dysfunction and could guide optimal therapeutic choices.

AB Anticoagulation has been shown to decrease ischemic stroke in atrial fibrillation (AF). However, concerns remain regarding their safety and efficacy in those <= 70 years of age who constitute most patients with AF. Of the 4,060 patients (mean age 65 years, range 49 to 80) in the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial, 2,248 (55% of 4,060) were 70 to 80 years of age, 1,901 of whom were receiving warfarin. Propensity score for warfarin use, estimated for each of the 2,248 patients, was used to match 227 of the 347 patients not on warfarin (in 1:1, 1:2, or 1:3 sets) to 616 patients on warfarin who were balanced in 45 baseline characteristics. All-cause mortality occurred in 18% and 33% of matched patients receiving and not receiving warfarin, respectively, during up to 6 years (mean 3.4) of follow-up (hazard ratio [HR] when warfarin use was compared to its nonuse 0.58, 95% confidence interval [CI] 0.43 to 0.77, p <0.001). All-cause hospitalization occurred in 64% and 67% of matched patients receiving and not receiving warfarin, respectively (HR associated with warfarin use 0.93, 95% CI 0.77 to 1.12, p = 0.423). Ischemic stroke occurred in 4% and 8% of matched patients receiving and not receiving warfarin, respectively (HR associated with warfarin use 0.57, 95% CI 0.31 to 1.04, p = 0.068). Major bleeding occurred in 7% and 10% of matched patients receiving and not receiving warfarin, respectively (HR associated with warfarin use 0.73, 95% CI 0.44 to 1.22, p = 0.229). In conclusion, warfarin use was associated with decreased mortality in septuagenarian patients with AF but had no association with hospitalization or major bleeding. Published by Elsevier Inc.

AB The development and clinical trial of a 5-session behavioral intervention for complicated bereavement (CB) is presented. We conceptualized CB in terms of Major Depression (MDD) and Post-traumatic Stress Disorder (PTSD) and consequently applied treatment components of Behavioral Activation and Therapeutic Exposure (BA-TE). In order to assure standardization of treatment, control costs, and engage patients, a multi-media, multi-context format was adopted to address avoidance and withdrawal behaviors conceptualized as central pathogenic responses in CB. Participants (N = 26) were assessed before and after BA-TE treatment via structured clinical interview and standardized questionnaires in terms of PTSD, MDD, CB, and health concerns. The number of days since the death of the loved one was widely variable and served as a covariate for all outcome analyses. ANCOVAS revealed statistically significant improvement, irrespective of how many days since death had elapsed prior to initiation of intervention, on structured interviews and self-report measures for most outcome variables.

AB An important precondition for the successful development of diagnostic assays of cerebrospinal fluid (CSF) biomarkers of age-related neurodegenerative diseases is an understanding of the dynamic nature of the CSF proteome during the normal aging process. In this study, a novel proteomic technology was used to quantify hundreds of proteins simultaneously in the CSF from 90 cognitively normal adults 21 to 85 years of age. SomaLogic's highly multiplexed proteomic platform can measure more than 800 proteins simultaneously from small volumes of biological fluids using novel slow off-rate modified aptamer (SOMAmer) protein affinity reagents with sensitivity, specificity, and dynamic ranges that meet or exceed those of enzyme-linked immunosorbent assays. In the first application of this technology to CSF, we detected 248 proteins that possessed signals greater than twofold over background. Several novel correlations between detected protein concentrations and age were discovered that indicate that both inflammation and response to injury in the central nervous system may increase with age. Applying this powerful proteomic approach to CSF provides potential new insight into the aging of the human central nervous system that may have utility in discovering new disease-related changes in the CSF proteome.

AB Bone marrow (BM) fibrosis is a feature of severe hyperparathyroidism. Consistent with this observation, mice expressing constitutively active parathyroid hormone (PTH)/PTH-related peptide receptors (PPR) in osteoblasts (PPR*Tg) display BM fibrosis. To obtain insight into the nature of BM fibrosis in such a model, a double-mutant mouse expressing constitutively active PPR and green fluorescent protein (GFP) under the control of the type I collagen promoter (PPR*Tg/GFP) was generated. Confocal microscopy and flow cytometry revealed the presence of a cell population expressing GFP (GFP) that was also positive for the hematopoietic marker CD45 in the BM of both PPR*Tg/GFP and control animals. This cell population was expanded in PPR*Tg/GFP. The existence of cells expressing both type I collagen and CD45 in the adult BM was confirmed by IHC and fluorescence-activated cell sorting. An analysis of total RNA extracted from sorted GFP+CD45 cells showed that these cells produced type I collagen and PTH/PTH-related peptide receptor and receptor activator for NF-kappa B mRNAs, further supporting their features of being both mesenchymal and hematopoietic lineages. Similar cells, known as fibrocytes, are also present in pathological fibroses. Our findings, thus, indicate that the BM is a permissive microenvironment for the differentiation of fibrocyte-like cells and raise the possibility that these cells could contribute to the pathogenesis of BM fibrosis.

This study explored the role of the NADPH oxidase Nox4 as a source of reactive oxygen species (ROS) involved in the development of diabetic cardiomyopathy. Phosphorothioated antisense (AS) or sense (S) oligonucleotides for Nox4 were administered for 2 wk to rats made diabetic by streptozotocin. NADPH oxidase activity, ROS generation, and the expression of Nox4, but Nox1 or Nox2, were increased in left ventricular tissue of the diabetic rats. Expression of molecular markers of hypertrophy and myofibrosis including fibronectin, collagen, alpha-smooth muscle actin, and beta-myosin heavy chain were also increased. These parameters were attenuated by the administration of AS but not S Nox4. Moreover, the impairment of contractility observed in diabetic rats was prevented in AS- but not S-treated animals. Exposure of cultured cardiac myocytes to 25 mM glucose [high glucose (HG)] increased NADPH oxidase activity, the expression of Nox4, and molecular markers of cardiac injury. These effects of HG were prevented in cells infected with adenoviral vector containing a dominant negative form of Nox4. This study provides strong evidence that Nox4 is an important source of ROS in the left ventricle and that Nox4-derived ROS contribute to cardiomyopathy at early stages of type 1 diabetes.

TI Genome-Wide Analysis of Copy Number Variants in Attention Deficit

AB Objective: Attention deficit hyperactivity disorder (ADHD) is a common, highly heritable psychiatric disorder. Because of its multifactorial etiology, however, identifying the genes involved has been difficult. The authors followed up on recent findings suggesting that rare copy number variants (CNVs) may be important for ADHD etiology.
Method: The authors performed a genome-wide analysis of large, rare CNVs (<1% population frequency) in children with ADHD (N=896) and comparison subjects (N=2,455) from the IMAGE II Consortium.
Results: The authors observed 1,562 individually rare CNVs >100 kb in size, which segregated into 912 independent loci. Overall, the rate of rare CNVs >100 kb was 1.15 times higher in ADHD case subjects relative to comparison subjects, with duplications spanning known genes showing a 1.2-fold enrichment. In accordance with a previous study, rare CNVs >500 kb showed the greatest enrichment (1.28-fold). CNVs identified in ADHD case subjects were significantly enriched for loci implicated in autism and in schizophrenia. Duplications spanning the CHRNA7 gene at chromosome 15q13.3 were associated with ADHD in single-locus analysis. This finding was consistently replicated in an additional 2,242 ADHD case subjects and 8,552 comparison subjects from four independent cohorts from the United Kingdom, the United States, and Canada. Presence of the duplication at 15q13.3 appeared to be associated with comorbid conduct disorder.
Conclusions: These findings support the enrichment of large, rare CNVs in ADHD and implicate duplications at 15q13.3 as a novel risk factor for ADHD. With a frequency of 0.6% in the populations investigated and a relatively large effect size (odds ratio=2.22, 95% confidence interval=1.5-3.6), this locus could be an important contributor to ADHD etiology.

AB Cryptosporidium is a major cause of diarrhea in children in developing countries. However, there is no vaccine available and little is known about immune responses to protective antigens. We investigated antibody responses to p23, a putative vaccine candidate, in children in Bangladesh with cryptosporidiosis and diarrhea (cases) and uninfected children with diarrhea (controls), and p23 gene polymorphisms in infecting species. Serum IgM, IgG, and IgA responses to p23 were significantly greater in cases than controls after three weeks of follow-up. Cases with acute diarrhea had significantly greater serum IgA and IgM responses than those with persistent diarrhea, which suggested an association with protection from prolonged disease. The p23 sequences were relatively conserved among infecting species and subtype families. Although most children were infected with Cryptosporidium hominis, there was a cross-reactive antibody response to C. parvum antigen. These results support further development of p23 as a vaccine candidate.

AB Mitochondrial morphology has been associated with numerous pathologies including cancer, diabetes, obesity and heart disease. However, the connection is poorly understood-in part due to the difficulty of characterizing the morphology. This impedes the use of morphology as a tool for disease detection/monitoring. Here, we use the Brownian motion of isolated mitochondria to characterize their size and shape in a high throughput fashion. By using treadmill exercise training, mitochondria from heart and gastrocnemius of Balb/c mice were modulated in size and used to investigate the protocol. Consistent with previous reports, the heart mitochondria of untrained mice increased 5% in diameter immediately after a single bout of moderate exercise ( 1.091 +/- 0.004 mu m) as compared to completely sedentary controls (1.040 +/- 0.022 mu m). In addition, no change was observed in the size of gastrocnemius mitochondria (1.025 +/- 0.018 mu m), which was also in agreement with previous studies. The method was also successfully applied to smaller Saccharomyces cerevisiae mitochondria.

AB Silicone, commonly used in cosmetic procedures owing to its presumed inertness, can yield serious sequelae including acute embolization and pneumonitis. Chronic pulmonary sequelae in response to silicone injection have not been previously described. We report a case of chronic progressive granulomatous pneumonitis in response to subcutaneous silicone injections in a transgender male-to-female patient infected with human immunodeficiency virus 1 (HIV-1). After receiving silicone injections to the buttock, the patient developed rapid onset dyspnea, pleuritic chest pain, fever, and chills. Chest computed tomography revealed diffuse peripheral interstitial opacities. She responded symptomatically to prednisone with subsequent intermittent symptomatic flares. Four years later, she developed marked dyspnea and cough. Chest computed tomography showed progressive diffuse ground-glass and nodular opacities. Lung biopsies demonstrated numerous spheroid silicone particles within the lung interstitium and small pulmonary vessels, surrounded by foreign body giant cells and nonnecrotizing granulomatous inflammation. We speculate that HIV-1-infected patients may be at risk for chronic, progressive granulomatous pneumonitis due to silicone injection years after their procedure owing to shifting levels of cell-mediated immunity.

AB Objective-Prediabetic states are associated with accelerated atherosclerosis, but the availability of mouse models to study connections between these diseases has been limited. The aim of this study was to test the selective role of impaired insulin receptor/insulin receptor substrate-1 signaling on atherogenesis.
Methods and Results-To address the effects of impaired insulin signaling associated with hyperinsulinemia on atherosclerosis in the absence of obesity and hyperglycemia, we generated insulin receptor (Insr)/insulin receptor substrate-1 (Insr1) double heterozygous apolipoprotein (Apoe)-knockout mice (Insr(+/-) Irs1(+/-) Apoe(-/-)) mice. Insr(+/-) Irs1(+/-) Apoe(-/-) mice fed a Western diet for 15 weeks showed elevated levels of fasting insulin compared to Insr(+/+) Irs1(+/+) Apoe(-/-) mice. There were no significant differences in glucose, triglyceride, HDL, VLDL, cholesterol levels or free fatty acid in the plasma of Insr(+/-) Irs1(+/-) Apoe(-/-) and Insr(+/+) Irs1(+/+) Apoe(-/-) mice. Atherosclerotic lesions were increased in male (brachiocephalic artery) and female (aortic tree) Insr(+/-) Irs1(+/-) Apoe(-/-) compared to Insr(+/+) Irs1(+/+) Apoe(-/-) mice. Bone marrow transfer experiments demonstrated that nonhematopoietic cells have to be Insr(+/-) Irs1(+/-) to accelerate atherosclerosis. Impaired insulin signaling resulted in decreased levels of vascular phospho-eNOS, attenuated endothelium-dependent vasorelaxation and elevated VCAM-1 expression in aortas of Insr(+/-) Irs1(+/-) Apoe(-/-) mice. In addition, phospho-ERK and vascular smooth muscle cell proliferation were significantly elevated in aortas of Insr(+/-) Irs1(+/-) Apoe(-/-) mice.
Conclusion-These results demonstrate that defective insulin signaling is involved in accelerated atherosclerosis in Insr(+/-) Irs1(+/-) Apoe(-/-) mice by promoting vascular dysfunction and inflammation. (Arterioscler Thromb Vasc Biol. 2012;32:247-256.)

REGENERATION
AB Spinal cord injury (SCI) presents a complex regenerative problem due to the multiple facets of growth inhibition that occur following trauma to the cord parenchyma and stroma. Clinically, SCI is further complicated by the heterogeneity in the size, shape and extent of human injuries. Many of these injuries do not breach the dura mater and have continuous viable axons through the injury site that can later lead to some degree of functional recovery. In these cases, surgical manipulation of the spinal cord by implanting a preformed scaffold or drug delivery device may lead to further damage. Given these circumstances, in situ-forming scaffolds are an attractive approach for SCI regeneration. These synthetic and natural polymers undergo a rapid transformation from liquid to gel upon injection into the cord tissue, conforming to the individual lesion site and directly integrating with the host tissue. Injectable materials can be formulated to have mechanical properties that closely match the native spinal cord extracellular matrix, and this may enhance axonal ingrowth. Such materials can also be loaded with cellular and molecular therapeutics to modulate the wound environment and enhance regeneration. This review will focus on the current status of in situ-forming materials for spinal cord repair. The advantages of, and requirements for, such polymers will be presented, and examples of the behavior of such systems in vitro and in vivo will be presented. There are helpful lessons to be learned from the investigations of injectable hydrogels for the treatment of SCI that apply to the use of these biomaterials for the treatment of lesions in other central nervous system tissues and in organs comprising other tissue types.

AB Background: Coffee has been hypothesized to have pro- and anticarcinogenic properties, whereas tea may contain anticarcinogenic compounds. Studies assessing coffee intake and pancreatic cancer risk have yielded mixed results, whereas findings for tea intake have mostly been null. Sugar-sweetened carbonated soft drink (SSB) intake has been associated with higher circulating levels of insulin, which may promote carcinogenesis. Few prospective studies have examined SSB intake and pancreatic cancer risk; results have been heterogeneous.
Methods: In this pooled analysis from 14 prospective cohort studies, 2,185 incident pancreatic cancer cases were identified among 853,894 individuals during follow-up. Multivariate (MV) study-specific relative risks (RR) and 95% confidence intervals (CI) were calculated using Cox proportional hazards models and then pooled using a random-effects model.
Results: No statistically significant associations were observed between pancreatic cancer risk and intake of coffee (MVRR = 1.10; 95% CI, 0.81-1.48 comparing >= 900 to <0 g/d; 237g approximate to 8oz), tea (MVRR = 0.96; 95% CI, 0.78-1.16 comparing >= 400 to 0 g/d; 237g approximate to 8oz), or SSB (MVRR = 1.19; 95% CI, 0.98-1.46 comparing >= 250 to 0 g/d; 355g approximate to 12oz; P value, test for between-studies heterogeneity > 0.05). These associations were consistent across levels of sex, smoking status, and body mass index. When modeled as a continuous variable, a positive association was evident for SSB (MVRR = 1.06; 95% CI, 1.02-1.12).
Conclusion and Impact: Overall, no associations were observed for intakes of coffee or tea during adulthood and pancreatic cancer risk. Although we were only able to examine modest intake of SSB, there was a suggestive, modest positive association for risk of pancreatic cancer for intakes of SSB.

AB Considerable evidence supports the effectiveness of aspirin for chemoprevention of colorectal cancer (CRC) in addition to its well-established benefits in the prevention of vascular disease. Epidemiologic studies have consistently observed an inverse association between aspirin use and risk of CRC. A recent pooled analysis of a long-term posttrial follow-up of nearly 14,000 patients from four randomized, cardiovascular disease prevention trials showed that daily aspirin treatment for about five years was associated with a 34% reduction in 20-year CRC mortality. A separate metaanalysis of nearly 3,000 patients with a history of colorectal adenoma or cancer in four randomized adenoma prevention trials showed that aspirin reduced the occurrence of advanced adenomas by 28% and any adenoma by 17%. Aspirin has also been shown to be beneficial in a clinical trial of patients with Lynch syndrome, a hereditary CRC syndrome; in those treated with aspirin for at least two years, there was a 50% or more reduction in the risk of CRC commencing five years after randomization and after aspirin had been discontinued. A few observational studies have shown an increase in survival among patients with CRC who use aspirin. Taken together, these findings strengthen the case for consideration of long-term aspirin use in CRC prevention. Despite these compelling data, there is a lack of consensus about the balance of risks and benefits associated with long-term aspirin use, particularly in low-risk populations. The optimal dose to use for cancer prevention and the precise mechanism underlying aspirin's anticancer effect require further investigation. Cancer Prev Res; 5(2); 164-78. (C) 2011 AACR.

AB Squamous cell carcinoma (SCC) and premalignant endobronchial lesions have been difficult to study in murine models. In this study, we evaluate the topical N-nitroso-tris-chloroethylurea (NTCU) murine SCC model, determine the extent to which resulting premalignant airway dysplasia develops, discuss clinicopathologic grading criteria in lesion progression, and confirm that immunohistochemical (IHC) staining patterns are consistent with those observed in human endobronchial dysplasia and SCC. Male and female FVB mice were treated biweekly with topical NTCU (4, 8, or 40 mmol/L) or vehicle for 32 weeks. Following sacrifice, squamous cell lesions were enumerated and categorized into the following groups: flat atypia, low-grade dysplasia, high-grade dysplasia, and invasive SCC. The 40 mmol/L NTCU concentration produced the entire spectrum of premalignant dysplasias and squamous cell carcinomas, but was associated with poor survival. Concentrations of 4 and 8 mmol/L NTCU were better tolerated and produced only significant levels of flat atypia. Squamous origin of the range of observed lesions was confirmed with IHC staining for cytokeratin 5/6, p63, thyroid transcription factor-1 (TTF-1), and Napsin-A. This study shows that topical application of high-dose NTCU produces endobronchial premalignant lesions with classic squamous characteristics and should allow for improved preclinical evaluation of potential chemopreventive agents.

AB A common treatment of advanced prostate cancer involves the deprivation of androgens. Despite the initial response to hormonal therapy, eventually all the patients relapse. In the present study, we sought to determine whether dietary polyunsaturated fatty acid (PUFA) affects the development of castration-resistant prostate cancer. Cell culture, patient tissue microarray, allograft, xenograft, prostate-specific Pten knockout and omega-3 desaturase transgenic mouse models in conjunction with dietary manipulation, gene knockdown and knockout approaches were used to determine the effect of dietary PUFA on castration-resistant Pten-null prostate cancer. We found that deletion of Pten increased androgen receptor (AR) expression and Pten-null prostate cells were castration resistant. Omega-3 PUFA slowed down the growth of castration-resistant tumors as compared with omega-6 PUFA. Omega-3 PUFA decreased AR protein to a similar extent in tumor cell cytosolic and nuclear fractions but had no effect on AR messenger RNA level. Omega-3 PUFA treatment appeared to accelerate AR protein degradation, which could be blocked by proteasome inhibitor MG132. Knockdown of AR significantly slowed down prostate cancer cell proliferation in the absence of androgens. Our data suggest that omega-3 PUFA inhibits castration-resistant prostate cancer in part by accelerating proteasome-dependent degradation of the AR protein. Dietary omega-3 PUFA supplementation in conjunction with androgen ablation may significantly delay the development of castration-resistant prostate cancer in patients compared with androgen ablation alone.

AB Long-term exposure to estrogen and its metabolites may play an important role in renal cell carcinogenesis. Catechol-O-methyltransferase (COMT) participates in the estrogen metabolism pathway by neutralizing toxic substances. Although reduced COMT activity has been suggested to be a risk factor for estrogen-associated cancers, no studies have investigated the biological significance of COMT in the pathogenesis of human renal cell cancers (RCCs). We initially found that COMT levels are significantly decreased in human RCC tissues and cells suggesting it plays a suppressive role in tumor development. However, transient overexpression of COMT has no functional effect on RCC cell lines. In contrast, when cells overexpressing COMT are treated with its substrate 4-hydroxyestradiol (4-OHE2), growth is inhibited by apoptotic cell death. We also found that COMT overexpression combined with 4-OHE2 induces upregulation of growth arrest- and DNA damage-inducible protein alpha (GADD45 alpha). We further show that downregulation of GADD45 alpha by a small interfering RNA-mediated approach inhibits cell death, indicating the essential role of GADD45 alpha in the underlying mechanism of COMT action in response to 4-OHE2. Finally, 4-methoxyestradiol fully reproduces the antiproliferative function of COMT with 4-OHE2 by promoting GADD45 alpha induction. Together, these findings show that COMT in the presence of 4-OHE2 prevents RCC cell proliferation by enhancing apoptosis and that GADD45 alpha plays a critical role in the COMT-mediated inhibition of RCC.

DT Article
ID CLINICAL CLASSIFICATION; REVEAL REGISTRY; SURVIVAL
AB Background: Pulmonary arterial hypertension (PAH) is a life-threatening disease that affects more women than men. The reasons for the female preponderance are unclear, and there are limited data available for men with PAH.
Methods: Data from the Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL Registry) were analyzed to explore sex differences among patients with PAH with regard to 2-year survival from enrollment and 5-year survival from time of diagnosis.
Results: The data set included 2,318 women and 651 men. More women had PAH associated with connective tissue disease (P < .001), and more men had portopulmonary hypertension (P <.001) and HIV-associated PAH (P < .001). More women had congenital heart disease-associated PAH (P = .017), thyroid disease (P < .001), and depression reported (P <= .001). At diagnosis, men had higher mean pulmonary artery pressure (53 +/- 14 vs 51 +/- 14.3 mm Fig; P = .013) and mean right atrial pressure (10 6 vs 9 6 mm Hg; P = .031). Women had better survival estimates for 2 years from enrollment and for 5 years from diagnosis. Stratifying by age showed that survival from enrollment was similar between men and women aged <60 years at enrollment, whereas men aged >= 60 years have lower survival rates compared with women aged >= 60 years.
Conclusions: Our findings highlight similarities and differences between men and women with PAH, raising questions for future exploration regarding the role of hormones and sex in causation and survival in PAH.

AB Objective: The objective of this study was to compare the safety, use, and cost profiles of open thoracotomy vs video-assisted thoracoscopic surgery (VATS) for wedge resection in lung cancer performed by thoracic surgeons in the United States.
Methods: The Premier database, which contains complete patient billing, hospital cost, and coding histories from > 25 million inpatient discharges and > 175 million hospital outpatient visits, was used for this analysis. Eligible patients were those who underwent wedge resection by a thoracic surgeon for cancer diagnosis or treatment through open thoracotomy or VATS in 2007 or 2008. Multivariable logistic regression analyses were run for binary outcomes, and ordinary least squares regressions were used for continuous outcomes. All models were adjusted for patient demographics, comorbid conditions, and hospital characteristics.
Results: Of 8,228 eligible procedures, 2,051 patients underwent wedge resections by a thoracic surgeon using the open technique (n = 999) or VATS (n = 1,052). Hospital costs remained significantly higher for open wedge resections than for VATS ($17,377 vs $14,795, P = .000). Surgery time was significantly longer for open resections vs VATS (3.16 vs 2.82 h). Length of stay was 6.34 days for open vs 4.44 days for VATS. Adverse events were significant in the multivariable analysis, with an OR of 1.57 (95% CI, 1.29-1.91) in favor of VATS.
Conclusions: Although this retrospective database analysis could not address the issue of oncologic outcome equivalence, a clear advantage of VATS over open wedge lung cancer resection was found for both acute clinical outcomes and hospital costs. CHEST 2012; 141(2):429-435

AB Substantial literature has linked bipolar disorder with creative accomplishment. Much of the thinking in this area has been inspired by biographical accounts of poets, musicians, and other highly accomplished groups, which frequently document signs of bipolar disorder in these samples. A smaller literature has examined quantitative measures of creativity among people with bipolar disorder or at risk for the disorder. In this paper, we provide a critical review of such evidence. We then consider putative mechanisms related to the link of bipolar disorder with creativity, by drawing on literature outside of bipolar disorder on personality, motivational, and affective predictors of creativity. Because so little research has directly evaluated whether these factors could help explain the elevations of creativity in bipolar disorder, we conclude with an agenda for future research on the theoretically and clinically compelling topic of creativity in bipolar disorder.

AB Higher body temperature is a prognostic factor of poor outcome in acute stroke. Our aim was to study the relationship between body temperature, HT (haemorrhagic transformation) and biomarkers of BBB (blood brain barrier) damage in patients with acute ischaemic stroke untreated with rtPA (recombinant tissue-type plasminogen activator). We studied 229 patients with ischaemic stroke <12 h from symptom onset. Body temperature was determined at admission and every 6 h during the first 3 days. HT was evaluated according to ECASS II (second European Co-operative Acute Stroke Study) criteria in a multimodal MRI (magnetic resonance imaging) at 72 h. We found that 55 patients (34.1%) showed HT. HT was associated with cardioembolic stroke (64.2% against 23.0%; P <0.0001), higher body temperature during the first 24 h (36.9 degrees C compared with 36.5 degrees C; P <0.0001), more severe stroke [NIHSS (National Institutes of Health Stroke Scale) score, 14 (9-20) against 10 (7-15); P = 0.002], and greater DWI (diffusion-weighted imaging) lesion volume at admission (23.2 cc compared with 13.2 cc; P <0.0001). Plasma MMP-9 (matrix metalloproteinase 9) (187.3 ng/ml compared with 44.2 ng/ml; P < 0.0001) and cFn (cellular fibronectin) levels (16.3 mu g/ml compared with 7.1 mu g/ml; P = 0.001) were higher in patients with HT. Body temperature within the first 24 h was independently associated with HT {OR (odds ratio), 7.3 [95% Cl (confidence interval), 2.4-22.6]; P < 0.0001} after adjustment for cardioembolic stroke subtype, baseline NIHSS score and DWI lesion volume. This effect remained unchanged after controlling for MMP-9 and cFn. In conclusion, high body temperature within the first 24 h after ischaemic stroke is a risk factor for HT in patients untreated with rtPA. This effect is independent of some biological signatures of BBB damage.

AB Perinatal loss, typically defined as fetal death beyond 20 weeks gestation through infant death 1-month postpartum, is a potentially traumatizing experience for parents occurring in approximately 1% of births in the United States. Although many women recover; 15% to 25% have enduring grief-related symptomatology and functional impairment. Perinatal grief is a unique bereavement experience, but clinical resources for detecting and treating severe perinatal grief are rare and interventions are largely without empirical support. We developed and pilot tested a cognitive-behavioral intervention targeting the psychological and behavioral sequelae of perinatal bereavement. To initially evaluate the feasibility and efficacy of the intervention, 5 women who suffered a perinatal loss were randomized to a 2-week, 4-week, or 6-week baseline period in a multiple-baseline single-case experimental design. In most cases, after the respective baseline periods, there was a steady decline in reported grief symptoms. These gains were largely maintained at a 6-week follow-up assessment. This study provides initial evidence in support of future research and clinical efforts tailoring cognitive behavioral interventions to meet the specific needs of women who experience perinatal loss.

AB Dysregulation of blood glucose and triglycerides are the major characteristics of type 2 diabetes mellitus. We sought to identify the mechanisms regulating blood glucose and lipid homeostasis. Cell-based studies established that the Foxo forkhead transcription factors Forkhead box O (Foxo)-1, Foxo3, and Foxo4 are inactivated by insulin via a phosphatidylinositol 3-kinase/Akt-dependent pathway, but the role of Foxo transcription factors in the liver in regulating nutrient metabolism is incompletely understood. In this study, we used the Cre/LoxP genetic approach to delete the Foxo1, Foxo3, and Foxo4 genes individually or a combination of two or all in the liver of lean or db/db mice and assessed the role of Foxo inactivation in regulating glucose and lipid homeostasis in vivo. In the lean mice or db/db mice, hepatic deletion of Foxo1, rather than Foxo3 or Foxo4, caused a modest reduction in blood glucose concentrations and barely affected lipid homeostasis. Combined deletion of Foxo1 and Foxo3 decreased blood glucose levels, elevated serum triglyceride and cholesterol concentrations, and increased hepatic lipid secretion and caused hepatosteatosis. Analysis of the liver transcripts established a prominent role of Foxo1 in regulating gene expression of gluconeogenic enzymes and Foxo3 in the expression of lipogenic enzymes. Our findings indicate that Foxo1 and Foxo3 inactivation serves as a potential mechanism by which insulin reduces hepatic glucose production and increases hepatic lipid synthesis and secretion in healthy and diabetic states.

AB Human anaplastic thyroid cancer (ATC) is a lethal disease with an advanced clinical presentation and median survival of 3 months. The BRAF(V600E) oncoprotein is a potent transforming factor that causes human thyroid cancer cell progression in vitro and in vivo; therefore, we sought to target this oncoprotein in a late intervention model of ATC in vivo. We used the human ATC cell line 8505c, which harbors the BRAF(V600E) and TP53(R248G) mutations. Immunocompromised mice were randomized to receive the selective anti-BRAF(V600E) inhibitor, PLX4720, or vehicle by oral gavage 28 d after tumor implantation, 1 wk before all animals typically die due to widespread metastatic lung disease and neck compressive symptoms in this model. Mice were euthanized weekly to evaluate tumor volume and metastases. Control mice showed progressive tumor growth and lung metastases by 35 d after tumor implantation. At that time, all control mice had large tumors, were cachectic, and were euthanized due to their tumor-related weight loss. PLX4720-treated mice, however, showed a significant decrease in tumor volume and lung metastases in addition to a reversal of tumor-related weight loss. Mouse survival was extended to 49 d in PLX4720-treated animals. PLX4720 treatment inhibited cell cycle progression from 28 d to 49 d in vivo. PLX4720 induces striking tumor regression and reversal of cachexia in an in vivo model of advanced thyroid cancer that harbors the BRAF(V600E) mutation. (Endocrinology 153: 985-994, 2012)

AB BACKGROUND: Diabetes increases the risk of hypertension and orthostatic hypotension and raises the risk of cardiovascular death during heat waves and high pollution episodes.
OBJECTIVE: We examined whether short-term exposures to air pollution (fine particles, ozone) and heat resulted in perturbation of arterial blood pressure (BP) in persons with type 2 diabetes mellitus (T2DM).
METHODS: We conducted a panel study in 70 subjects with T2DM, measuring BP by automated oscillometric sphygmomanometer and pulse wave analysis every 2 weeks on up to five occasions (355 repeated measures). Hourly central site measurements of fine particles, ozone, and meteorology were conducted. We applied linear mixed models with random participant intercepts to investigate the association of fine particles, ozone, and ambient temperature with systolic, diastolic, and mean arterial BP in a multipollutant model, controlling for season, meteorological variables, and subject characteristics.
RESULTS: An interquartile increase in ambient fine particle mass [particulate matter (PM) with an aerodynamic diameter of <= 2.5 mu m (PM2.5)] and in the traffic component black carbon in the previous 5 days (3.54 and 0.25 mu g/m(3), respectively) predicted increases of 1.4 mmHg (95% confidence interval (CI): 0.0, 2.9 mmHg] and 2.2 mmHg (95% CI: 0.4, 4.0 mmHg) in systolic BP (SBP) at the population geometric mean, respectively. In contrast, an interquartile increase in the 5-day mean of ozone (13.3 ppb) was associated with a 5.2 mmHg (95% CI: -8.6, -1.8 mmHg) decrease in SBP. Higher temperatures were associated with a marginal decrease in BP.
CONCLUSIONS: In subjects with T2DM, PM was associated with increased BP, and ozone was associated with decreased BP. These effects may be clinically important in patients with already compromised autoregulatory function.

AB BACKGROUND: Hexachlorobenzene (HCB), dichlorodiphenyltrichloroethane (DDT), and dichlorodiphenyldichloroethylene (DDE) are persistent chlorinated pesticides with endocrine activity that may adversely affect the early stages of human reproduction.
OBJECTIVE: Our goal was to determine the association of serum levels of HCB, DDT, and DDE with implantation failure, chemical pregnancy, and spontaneous abortion in women undergoing in vitro fertilization (IVF) from 1994 to 2003.
METHODS: Levels of HCB and congeners of DDT and DDE were measured in serum collected during the follicular phase. Multivariable-adjusted statistical models accommodating multiple outcomes and multiple cycles per woman were used to estimate the relation between serum pesticide levels and WE outcomes.
RESULTS: A total of 720 women with a mean +/- SD age 35.4 +/- 4.2 years at enrollment contributed 774 IVF cycles. All samples had detectable levels of HCB, DDT, and DDE, with median levels of 0.087 ng/g serum for HCB, 1.12 ng/g serum for total DDT, and 1.04 ng/g serum for p,p'-DDE. Compared with the lowest quartile (Q1) of HCB, the lipid- and multivariable-adjusted odds ratio (OR) for failed implantation was significantly elevated for those with higher HCB quartiles [Q2-Q4; adjusted ORs: for Q2, 1.71; 95% confidence interval (CI): 1.03, 2.82; for Q3, 2.30; 95% CI: 1.39, 3.81; for Q4, 2.32; 95% CI: 1.38, 3.90] and showed a significantly increasing trend (p = 0.001). No statistically significant associations were observed between DDT/DDE and IVF outcomes or between HCB and chemical pregnancy or spontaneous abortion.
CONCLUSIONS: Serum HCB concentrations were on average lower than that of the general U.S. population and associated with failed implantation among women undergoing IVF.

TI Revising the "Rule of Three" for inferring seizure freedom
SO EPILEPSIA
LA English
DT Article
DE Bayes' rule; ILAE; Epilepsy; Refractory; Statistical prediction
ID EPILEPSY
AB Purpose: How long after starting a new medication must a patient go without seizures before they can be regarded as seizure-free? A recent International League Against Epilepsy (ILAE) task force proposed using a Rule of Three as an operational definition of seizure freedom, according to which a patient should be considered seizure-free following an intervention after a period without seizures has elapsed equal to three times the longest preintervention interseizure interval over the previous year. This rule was motivated in large part by statistical considerations advanced in a classic 1983 paper by Hanley and Lippman-Hand. However, strict adherence to the statistical logic of this rule generally requires waiting much longer than recommended by the ILAE task force. Therefore, we set out to determine whether an alternative approach to the Rule of Three might be possible, and under what conditions the rule may be expected to hold or would need to be extended.
Methods: Probabilistic modeling and application of Bayes' rule.
Key Findings: We find that an alternative approach to the problem of inferring seizure freedom supports using the Rule of Three in the way proposed by the ILAE in many cases, particularly in evaluating responses to a first trial of antiseizure medication, and to favorably-selected epilepsy surgical candidates. In cases where the a priori odds of success are less favorable, our analysis requires longer seizure-free observation periods before declaring seizure freedom, up to six times the average preintervention interseizure interval. The key to our approach is to take into account not only the time elapsed without seizures but also empirical data regarding the a priori probability of achieving seizure freedom conferred by a particular intervention.
Significance: In many cases it may be reasonable to consider a patient seizure-free after they have gone without seizures for a period equal to three times the preintervention interseizure interval, as proposed on pragmatic grounds in a recent ILAE position paper, although in other commonly encountered cases a waiting time up to six times this interval is required. In this work we have provided a coherent theoretical basis for modified criterion for seizure freedom, which we call the "Rule of Three-To-Six.''

AB The role of biventricular pacing is expanding beyond the New York Heart Association classes III and IV heart failure ( HF) patient to include less symptomatic patients, earlier in the course of their disease process. This multisite pacing strategy has substantially altered the natural course of ventricular failure, exerting its physiological impact through favourable cardiac remodelling and improving the ejection fraction. This has in turn resulted in long-term clinical benefits such as improved quality of life and functional capacity with a concomitant reduction in hospitalization for HF and overall mortality. Despite the successes of cardiac resynchronization therapy (CRT) and the recent expansion of its role in the treatment of HF patients, there remain some inherent limitations to the technology and its delivery. A significant minority of patients continue to remain non-responsive to this pacing strategy. This review will highlight biventricular pacing in its present form, will elaborate on strategies to enhance response to CRT, and outline future trends and synergies towards maximizing the potential benefit of this therapeutic modality.

HYPOPITUITARISM; ESTROGEN
AB Objective: To investigate whether testosterone administration alters natriuretic peptide levels in women.
Design: Three-month, double-blind, randomized, placebo-controlled study.
Setting: Clinical research center.
Patient(s): Fifty-one women with hypoandrogenemia due to hypopituitarism.
Intervention(s): Transdermal testosterone (300 mg daily) or placebo patch.
Main Outcome Measure(s): N-Terminal pro-B-type natriuretic peptide (NT-proBNP) levels.
Result(s): NT-proBNP levels decreased in the transdermal testosterone group compared with placebo over three months. The difference between groups remained significant after controlling for baseline age, systolic blood pressure, body mass index, and homeostasis model assessment of insulin resistance. Change in NT-proBNP over 3 months was inversely associated with change in free testosterone levels.
Conclusion(s): Testosterone administration to women results in decreased natriuretic peptide levels, suggesting that testosterone may be an inverse regulator of the natriuretic peptide system.

AB Certain white adipose tissue (WAT) depots are readily able to convert to a "brown-like" state with prolonged cold exposure or exposure to beta-adrenergic compounds. This process is characterized by the appearance of pockets of uncoupling protein 1 (UCP1)-positive, multilocular adipocytes and serves to increase the thermogenic capacity of the organism. We show here that fibroblast growth factor 21 (FGF21) plays a physiologic role in this thermogenic recruitment of WATs. In fact, mice deficient in FGF21 display an impaired ability to adapt to chronic cold exposure, with diminished browning of WAT. Adipose-derived FGF21 acts in an autocrine/paracrine manner to increase expression of UCP1 and other thermogenic genes in fat tissues. FGF21 regulates this process, at least in part, by enhancing adipose tissue PGC-1 alpha protein levels independently of mRNA expression. We conclude that FGF21 acts to activate and expand the thermogenic machinery in vivo to provide a robust defense against hypothermia.

AB BACKGROUND: Non-high density lipoprotein cholesterol (non-HDL-C) goal attainment per Adult Treatment Panel III (ATP III) guidelines remains low.
OBJECTIVE: To understand gaps in knowledge and practices of physicians-in-training (internal medicine, family medicine, cardiology, endocrinology) towards non-HDL-C.
METHODS: A survey based on a conceptual model to assess the trainee's knowledge, attitudes, and practice regarding non-HDL-C was developed and administered to physicians-in-training (n = 655) at 26 training programs in the United States. Responses of those in internal medicine and family medicine (residents-in-training; n = 418) were compared with those in cardiology and endocrinology (fellows-in-training; n = 124).
RESULTS: Response rate was 83.7%. Fifty-three percent of residents and 31% of fellows-in-training had not read the ATP III guidelines (P < .001). Thirty-three percent of the residents and 35% fellows-in-training could not calculate non-HDL-C from a standard lipid panel (P = .7). Sixty-seven percent of the residents and 52% of fellows were not aware of treatment goals for non-HDL-C (P = .004 for comparison between residents and fellows). Both residents and fellows reported infrequent calculation of non-HDL-C levels in patients with elevated triglycerides (>= 200 mg/dL; 32.5% vs 35.4%, respectively, P = .6). Lack of familiarity with ATP 111 guidelines, lack of knowledge regarding importance of non-HDL-C, lack of institutional mandate to calculate non-HDL-C, and lack of emphasis on non-HDL-C by teaching staff were reported as barriers to non-HDL-C use in routine clinical practice.
CONCLUSIONS: At least one-third of physicians-in-training could not calculate non-HDL-C from a standard lipid panel, and a large number were not aware of ATP III treatment goals pertaining to non-HDL-C. This area represents one for improvement if non-HDL-C is to be retained as a treatment target in the forthcoming ATP-IV guidelines. Published by Elsevier Inc on behalf of National Lipid Association.

AB Purpose: To evaluate longer outcomes of primary nitinol stenting for the treatment of femoropopliteal lesions up to 15 cm long after these stents were found to have superior short-term patency vs. balloon angioplasty.
Methods: Two hundred and six patients (143 men; mean age 67 years) with intermittent claudication due to superficial femoral and proximal popliteal artery lesions were randomized (2:1) to treatment with nitinol stents or balloon angioplasty at 24 US and European centers and followed for 3 years. In that time, 15 patients died, 20 withdrew consent, and 10 were lost to follow-up, leaving 161 (78.2%) patients for 36-month assessment.
Results: The 12-month freedom from target lesion revascularization (TLR) was 87.3% for the stent group vs. 45.2% for the angioplasty group (p<0.0001). At 3 years, there was no difference in survival (90.0% vs. 91.7%, p=0.71) or major adverse events (75.2% vs. 75.2%, p=0.98) between the stent and angioplasty groups. Duplex ultrasound was not mandated after the first year, so stent patency could not be ascertained beyond 1 year, but freedom from TLR at 3 years was significantly better in the stent group (75.5% vs. 41.8%, p<0.0001), as was clinical success (63.2% vs. 17.9%, p<0.0001). At 18 months, a 4.1% (12/291) stent fracture rate was documented.
Conclusion: In this multicenter trial, primary implantation of a nitinol stent for moderate-length lesions in the femoropopliteal segment of patients with claudication was associated with better long-term results vs. balloon angioplasty alone. J Endovasc Ther. 2012;19:1-9

AB Incarceration is associated with poor health and high costs. Given the dramatic growth in the criminal justice system's population and associated expenses, inclusion of questions related to incarceration in national health data sets could provide essential data to researchers, clinicians and policy-makers.
To evaluate a representative sample of publically available national health data sets for their ability to be used to study the health of currently or formerly incarcerated persons and to identify opportunities to improve criminal justice questions in health data sets.
We reviewed the 36 data sets from the Society of General Internal Medicine Dataset Compendium related to individual health. Through content analysis using incarceration-related keywords, we identified data sets that could be used to study currently or formerly incarcerated persons, and we identified opportunities to improve the availability of relevant data.
While 12 (33%) data sets returned keyword matches, none could be used to study incarcerated persons. Three (8%) could be used to study the health of formerly incarcerated individuals, but only one data set included multiple questions such as length of incarceration and age at incarceration. Missed opportunities included: (1) data sets that included current prisoners but did not record their status (10, 28%); (2) data sets that asked questions related to incarceration but did not specifically record a subject's status as formerly incarcerated (8, 22%); and (3) longitudinal studies that dropped and/or failed to record persons who became incarcerated during the study (8, 22%).
Few health data sets can be used to evaluate the association between incarceration and health. Three types of changes to existing national health data sets could substantially expand the available data, including: recording incarceration status for study participants who are incarcerated; recording subjects' history of incarceration when this data is already being collected; and expanding incarceration-related questions in studies that already record incarceration history.

AB The performance of scoring tools to select clinical vignettes for presentation at academic meetings has never been assessed.
To measure the psychometric properties of two scoring tools used to select clinical vignettes and to determine which elements are most helpful.
Prospective observational study.
Participants submitting clinical vignette abstracts, Society of General Internal Medicine annual meetings (2006-2007).
The 2006 scoring tool had three criteria (clarity, significance, and relevance) with brief general descriptors. The 2007 modified tool had five criteria (clarity, significance, relevance, teaching value, and overall assessment) with more detailed descriptors.
A total of 938 clinical vignette abstracts were submitted (484 in 2006; 454 in 2007); 59.5% (n = 288) were accepted for presentation. Cronbach's alpha was 0.81 for the 2006 three-item tool and 0.95 for the 2007 modified five-item tool. Simplifying the five-item 2007 tool to three items (relevance, teaching value, overall assessment) yielded a Cronbach's alpha of 0.95. The agreement between the number of clinical vignettes accepted for presentation (2007) using the average score of the five items with the number that would have been accepted using the simplified three items (relevance, teaching value, overall assessment) was almost perfect, with kappa 0.89 (95% confidence interval, 0.85 to 0.93).
Both scoring tools performed well, but a simplified tool with three items (relevance, teaching value, and overall assessment) and detailed descriptors was optimal; the simplified tool could improve the reviewer efficiency and quality of clinical vignettes presented at national meetings.

AB Purpose Some patients report a transient increase in pain the day after a corticosteroid injection. We investigated factors associated with greater pain during and the day after a corticosteroid injection for idiopathic trigger finger.
Methods A total of 100 patients with trigger finger completed questionnaires measuring heightened illness concern, catastrophic thinking, depression, perceived health, expected pain, pain with injection, and pain the day after injection. We performed bivariate analysis to determine variables associated with pain with injection, next-day pain, and next-day pain greater than 4 points on an 11-point ordinal scale. We entered variables with a significant correlation into multivariable linear regression models.
Results The average pain with injection and the day after injection were 4.3 (SD 2.8) and 1.8 (SD 2.0), respectively. Expected pain, heightened illness concern, catastrophic thinking, depression, physician, and gender correlated with pain with injection. A multivariable regression model conducted in backward stepwise fashion demonstrated that physician, depression, expected pain, and female gender explained 28% of the variance in pain with injection. Pain with injection was the only significant predictor of next-day pain and pain greater than 4 points the day after injection.
Conclusions Our data suggest that psychosocial factors are the strongest correlates of pain with corticosteroid injection, but a large portion of the variability remains unexplained. Future research will investigate cognitive/behavioral methods for decreasing pain with injection. (J Hand Surg 2012;37A:237-242. Copyright (C) 2012 by the American Society for Surgery of the Hand.

ID OBSERVER AGREEMENT; RADIOGRAPHY; SIGNS
AB Purpose To determine the interobserver agreement and diagnostic performance characteristics of computed tomography (CT) for determining union of scaphoid waist fractures.
Methods A total of 59 orthopedic and trauma surgeons rated for union a set of 30 sagittal CT scans of 30 scaphoid waist fractures. Of these fractures, 20 were treated nonoperatively, were imaged between 6 and 10 weeks after injury, and were known to have eventually achieved union. Ten were operatively confirmed to be ununited. We rated each scan as united or ununited using a Web-based rating application. We assessed interobserver reliability using Siegel's multirater Kappa. We calculated diagnostic performance characteristics using Bayesian formulas.
Results The interobserver agreement among 59 raters was substantial. The average sensitivity, specificity, and accuracy of diagnosing union of scaphoid waist fractures on sagittal CT scans were 78%, 96%, and 84%, respectively. Assuming a 90% prevalence of fracture union of the scaphoid, the positive predictive value of a diagnosis of union on sagittal CT scan was 0.99 and the negative predictive value was 0.41.
Conclusions Our results suggest that CT scans are accurate and reliable for diagnosis of union but inadequate for ruling out nonunion of scaphoid waist fractures between 6 and 10 weeks after injury.

ID CLINICAL QUESTIONS; CLAIMS DATA; PATIENT-CARE; ASSOCIATION; QUALITY;
EFFICIENCY; OBSTACLES; DATABASE; ANSWER; IMPACT
AB BACKGROUND: Computerized clinical knowledge mana-gement systems hold enormous potential for improving quality and efficiency. However, their impact on clinical practice is not well known.
OBJECTIVE: To examine the impact of UpToDate on outcomes of care.
DESIGN: Retrospective study.
SETTING: National sample of US inpatient hospitals.
PATIENTS: Fee-for-service Medicare beneficiaries.
INTERVENTION: Adoption of UpToDate in US hospitals.
MEASUREMENT: Risk-adjusted lengths of stay, mortality rates, and quality performance.
RESULTS: We found that patients admitted to hospitals using UpToDate had shorter lengths of stay than patients admitted to non-UpToDate hospitals overall (5.6 days vs 5.7 days; P < 0.001) and among 6 prespecified conditions (range, -0.1 to -0.3 days; P < 0.001 for each). Further, patients admitted to UpToDate hospitals had lower riskadjusted mortality rate for 3 of the 6 conditions (range, -0.1% to -0.6% mortality reduction; P < 0.05). Finally, hospitals with UpToDate had better quality performance for every condition on the Hospital Quality Alliance metrics. In subgroup analyses, we found that it was the smaller hospitals and the non-teaching hospitals where the benefits of the UpToDate seemed most pronounced, compared to the larger, teaching institutions where the benefits of UpToDate seemed small or nonexistent.
CONCLUSIONS: We found a very small but consistent association between use of UpToDate and reduced length of stay, lower risk-adjusted mortality rates, and better quality performance, at least in the smaller, non-teaching institutions. These findings may suggest that computerized tools such as UpToDate could be helpful in improving care. Journal of Hospital Medicine 2012; 7: 85-90 (C) 2011 Society of Hospital Medicine

COMBINATION
AB BACKGROUND: Vancomycin troughs of 15-20 mg/L are recommended in the treatment of invasive staphylococcal disease, higher levels than previously recommended.
OBJECTIVE/SETTING: We sought to determine if there was an association between vancomycin trough and nephrotoxicity, defined as 0.5 mg/L or 50% increase in serum creatinine, at a large Veterans Affairs medical center.
PATIENTS AND METHODS: We reviewed records of 348 inpatients at our institution who received >= 5 days of vancomycin during 2 time periods when vancomycin dosing protocols differed (May 2005-April 2006 and January 2007December 2007). Potential risk factors for nephrotoxicity were collected prior to nephrotoxicity onset, and all patients with nephrotoxicity events occurring within 5 days of starting vancomycin were excluded.
RESULTS: Overall incidence of nephrotoxicity was 31/348 patients (8.9%). A similar percentage of patients experienced nephrotoxicity in 2005-2006 versus 2007 (16/201 vs 15/147, respectively; P = 0.57), despite a rise in mean (9.7 mg/L in 2005-2006 vs 13.2 mg/L in 2007; P < 0.0001) and highest (11.8 mg/L in 2005-2006 vs 15.7 mg/L in 2007; P < 0.0001) vancomycin trough levels achieved. In a multivariate logistic regression model, only receipt of intravenous contrast dye was significantly associated with nephrotoxicity (OR 4.01, P < 0.001), though there was a trend toward an association between maximum vancomycin trough >= 15 mg/L and nephrotoxicity (OR 2.05, P = 0.082). Overall reversibility of nephrotoxicity either prior to or within 72 hours of vancomycin discontinuation was 77.8%.

TI Patients' diverse beliefs about what happens at the time of death
SO JOURNAL OF HOSPITAL MEDICINE
LA English
DT Article
ID LIFE DECISION-MAKING; MEDICAL PROCEDURES; CULTURAL ISSUES;
CANCER-PATIENTS; END; CARE; INFORMATION; STRATEGIES
AB BACKGROUND: Beliefs about what happens at the time of death surely affect a patient's whole dying experience and could help guide end-of-life care. Yet virtually no research describes those beliefs. This exploratory study begins the descriptive process.
METHODS: Assuming culture is key, we interviewed 26 Mexican-American (MA), 18 Euro-American (EA), and 14 African-American (AA) inpatients about their beliefs concerning what happens at the time of death.
RESULTS: One belief, that death separates the dead from the living, was widespread. Majorities of all 3 ethnic group samples and of 5 of the 6 gender subsamples expressed this belief, saying the dead "go" or "leave" from this life. Other beliefs differed by ethnic group or gender. For example, more EAs (50%) than others said death is a momentary event, and more MAs (35%) than others said death involves "being taken" by an external force (always God or Jesus). Furthermore, considerably more EA women (45%) than others said some senses persist after death. In contrast, the physiologic signs that participants cited as defining the exact time of death varied from individual to individual with no ethnic or gender pattern, and no one sign predominated.
CONCLUSIONS: A few beliefs about what happens at the time of death may characterize Americans in general; many other beliefs may characterize only certain ethnic groups, genders, or individuals. To identify such beliefs and to use them to guide end-of-life care, hospitalists and other health professionals may have to elicit them directly from patients or survivors.

AB BACKGROUND: Studies suggest that the inpatient to outpatient transition of care is a vulnerable period for patients, and socioeconomically disadvantaged populations may be particularly susceptible.
OBJECTIVE: In this prospective cohort study, clustered by hospital, we sought to determine the feasibility and utility of a simple, post-discharge intervention in reducing hospital readmissions.
METHODS: Chronically ill Medicaid managed care members were consecutively identified from the discharge records of 10 area hospitals. For patients from the 7 intervention hospitals, trained medical assistants performed a brief telephone needs assessment, within 1 week of discharge, in which issues requiring near-term resolution were identified and addressed. Patients with more complicated care needs were identified according to a 4domain care needs framework and enrolled in more intensive care management. Patients discharged from the 3 control hospitals received usual care. We used a generalized estimating equation model, which adjusts for clustering by hospital, to evaluate the primary outcome of hospital readmission within 60 days.
RESULTS: There were 97 intervention and 130 control patients. Intervention patients were slightly younger and had higher adjusted clinical group (ACG) scores. In unadjusted analysis, the intervention group had lower, but statistically similar, 60-day rehospitalization rates (23.7% vs 29.2%, P =0.35). This difference became significant after controlling for ACG score, prior inpatient utilization, and age: adjusted odds ratio (OR) [95% confidence interval (CI)] 0.49 [0.24-1.00].
CONCLUSIONS: A simple post-discharge intervention and needs assessment may be associated with reduced recurrent hospitalization rates in a cohort of chronically ill Medicaid managed care patients with diverse care needs.

AB Rett syndrome (RTT) results from loss-of-function mutations in the gene encoding the methyl-CpG-binding protein 2 (MeCP2) and is characterized by abnormal motor, respiratory and autonomic control, cognitive impairment, autistic-like behaviors and increased risk of seizures. RTT patients and Mecp2-null mice exhibit reduced expression of brain-derived neurotrophic factor (BDNF), which has been linked in mice to increased respiratory frequency, a hallmark of RTT. The present study was undertaken to test the hypotheses that BDNF deficits in Mecp2 mutants are associated with reduced activation of the BDNF receptor, TrkB, and that pharmacologic activation of TrkB would improve respiratory function. We characterized BDNF protein expression, TrkB activation and respiration in heterozygous female Mecp2 mutant mice (Het), a model that recapitulates the somatic mosaicism for mutant MECP2 found in typical RTT patients, and evaluated the ability of a small molecule TrkB agonist, LM22A-4, to ameliorate biochemical and functional abnormalities in these animals. We found that Het mice exhibit (1) reduced BDNF expression and TrkB activation in the medulla and pons and (2) breathing dysfunction, characterized by increased frequency due to periods of tachypnea, and increased apneas, as in RTT patients. Treatment of Het mice with LM22A-4 for 4 weeks rescued wild-type levels of TrkB phosphorylation in the medulla and pons and restored wild-type breathing frequency. These data provide new insight into the role of BDNF signaling deficits in the pathophysiology of RTT and highlight TrkB as a possible therapeutic target in this disease.

TI Multilocularity as a Radiographic Marker of the Keratocystic Odontogenic
Tumor
SO JOURNAL OF ORAL AND MAXILLOFACIAL SURGERY
LA English
DT Article
AB Purpose: The purpose of this study was to answer this clinical question: When a patient presents with a radiolucent lesion of the mandible presumed to be an odontogenic cystic lesion, to what extent is the radiographic finding of multilocularity predictive of a final diagnosis of keratocystic odontogenic tumor (KCOT)?
Materials and Methods: The study sample was derived from the population of patients who presented to the Department of Oral and Maxillofacial Surgery, Massachusetts General Hospital for evaluation and management of suspected mandibular lesions from January 1991 through January 2009. Subjects were eligible for study inclusion if there was a final histologic diagnosis of KCOT or dentigerous cyst. The predictor variable was radiographic appearance of the lesion and was grouped into 2 categories (unilocular or multilocular). The outcome variable was lesion type (KCOT or dentigerous cyst). Appropriate univariate, bivariate, and multivariate statistics were computed. Statistical significance was defined as P < .05.
Results: The study consisted of 130 subjects. Multilocular lesions were 1.7 times more likely to be KCOTs than unilocular lesions (P = .0001). The sensitivity, specificity, and positive and negative predictive values were 0.48, 0.87, 0.86, and 0.49, respectively. In the multiple logistic regression model, a multilocular radiographic appearance was associated with a 12-fold (95% confidence interval, 3.7 to 38) increased risk of KCOT.
Conclusion: The results of this study confirm the hypothesis that radiographic multilocularity is predictive of a KCOT because it is associated with a 12-fold increased risk for the diagnosis of KCOT.

DT Review
ID GRADUAL DISTRACTION; BONE DISTRACTION; DEVICE; FREQUENCY; REGENERATION;
MINIPIGS; FORCES; SHEEP
AB Purpose: Current devices for mandibular distraction osteogenesis ( DO) are complex and require significant patient or family skill during active distraction. Successful development of an automated, continuous distraction device would eliminate the need for patient participation in this process. The purpose of this study was to comprehensively review devices currently in development for continuous DO and to identify and evaluate the achieved successes and remaining problems.
Materials and Methods: A PubMed search of the English language literature in October 2008 using the keywords automatic or automated or continuous or hydraulic or motor or magnetic or spring and distraction osteogenesis was performed. The search included all technical notes, animal studies, and human studies describing the use of any automated continuous distraction device for the mandible. Excluded were studies using distraction devices employing hydraulics, motors, or springs that did not distract automatically and continuously and devices used for bones other than the mandible.
Results: The search returned 97 matches. Of these, 12 articles were selected as relevant to this review based on the inclusion and exclusion criteria detailed above. Eight distinct devices for automated, continuous DO were described in these reports and evaluated in this review. These included motor-driven, spring-mediated, and hydraulically powered distractors.
Conclusions: The abundance of research currently underway to develop a continuous distractor highlights the clinical demand for, and usefulness, of such a device. Despite many advances and promising results, significant problems remain to be overcome before any of these devices gain widespread clinical acceptance.

AB Background: Unwanted tattoos are treated with Q-switched lasers. Despite a series of treatments, efficacy is limited.
Objective: We compared a single Q-switched laser treatment pass with 4 treatment passes separated by 20 minutes.
Methods: Eighteen tattoos on 12 adults were divided in half and randomized. One half received a single treatment pass (the "conventional" method) with a Q-switched alexandrite laser (5.5 J/cm(2), 755 nm, 100-nanosecond pulse duration, 3-mm spot size), and the other half received 4 treatment passes with an interval of 20 minutes between passes (the "R20" method). Tattoo lightening was compared 3 months later, by blinded evaluation of photographs. Biopsy specimens obtained before and immediately after treatment on both halves were also compared in blinded fashion.
Results: Immediate whitening reaction occurred on the first treatment pass, with little or no whitening on subsequent passes. Three months later, treatment with the R20 method was much more effective than conventional single-pass laser treatment (P <.01; all tattoos favored the R20 method). Despite greater epidermal injury with the R20 method, neither method caused adverse events or scarring. Light microscopy showed greater dispersion of tattoo ink with the R20 method.
Limitations: This prospective study involved a small number of subjects.
Conclusions: The R20 method is much more effective than conventional laser tattoo treatment, removing most tattoos in a single treatment session. New laser device technology is not required to practice this method. (J Am Acad Dermatol 2012;66:271-7.)

AB The formation of replication compartments, the subnuclear structures in which the viral DNA genome is replicated, is a hallmark of hapesvirus infections. The localization of proteins and viral DNA within human cytomegalovirus replication compartments is not well characterized. Immunofluorescence analysis demonstrated the accumulation of the viral DNA polymerase subunit UL44 at the periphery of replication compartments and the presence of different populations of UL44 in infected cells. In contrast, the viral single-stranded-DNA binding protein UL57 was distributed throughout replication compartments. Using "click chemistry" to detect 5-ethyny1-2'-deoxyuridine (EdU) incorporation into replicating viral DNA and pulse-chase protocols, we found that viral DNA synthesis occurs at the periphery of replication compartments and that replicated viral DNA subsequently localizes to the interior of replication compartments. The interiors of replication compartments also contain regions in which UL44 and EdU-labeled DNA are absent. The treatment of cells with a viral DNA polymerase inhibitor reversibly caused the dispersal of both 1JL44 and EdU-labeled viral DNA from replication compartments, indicating that ongoing viral DNA synthesis is necessary to maintain the organization of replication compartments. Our results reveal a previously unappreciated complexity of the organization of human cytomegalovirus replication compartments.

AB Broad and potent neutralizing antibody (BNAb) responses are rare in people infected by human immunodeficiency virus type 1 (HIV-1). Clearly defining the nature of BNAb epitopes on HIV-1 envelope glycoproteins (Envs) targeted in vivo is critical for future directions of anti-HIV-1 vaccine development. Conventional techniques are successful in defining neutralizing epitopes in a small number of individual subjects but fail in studying large groups of subjects. Two independent methods were employed to investigate the nature of NAb epitopes targeted in 9 subjects, identified by the MAID Center for EUV/AIDS Vaccine Immunology (CHAVI) 001 and 008 clinical teams, known to make a strong BNAb response. Neutralizing activity from 8/9 subjects was enhanced by enriching high-mannose N-linked glycan (HM-glycan) of HIV-1 glycoproteins on neutralization target viruses and was sensitive to specific glycan deletion mutations of HIV-1 glycoproteins, indicating that HM-glycan-dependent epitopes are targeted by BNAb responses in these subjects. This discovery adds to accumulating evidence supporting the hypothesis that glycans are important targets on HIV-1 glycoproteins for BNAb responses in vivo, providing an important lead for future directions in developing NAb-based anti-HIV-1 vaccines.

AB There is a growing need for diagnostic technologies that provide laboratories with solutions that improve quality, enhance laboratory system productivity, and provide accurate detection of a broad range of infectious diseases and cancers. Recent advances in micro- and nanoscience and engineering, in particular in the areas of particles and microfluidic technologies, have advanced the "lab-on-a-chip" concept towards the development of a new generation of point-of-care diagnostic devices that could significantly enhance test sensitivity and speed. In this review, we will discuss many of the recent advances in microfluidics and particle technologies with an eye towards merging these two technologies for application in medical diagnostics. Although the potential diagnostic applications are virtually unlimited, the most important applications are foreseen in the areas of biomarker research, cancer diagnosis, and detection of infectious microorganisms.

TI AICAR prevents heat-induced sudden death in RyR1 mutant mice independent

IDENTIFICATION
AB Mice with a knock-in mutation (Y524S) in the type I ryanodine receptor (Ryr1), a mutation analogous to the Y522S mutation that is associated with malignant hyperthermia in humans, die when exposed to short periods of temperature elevation (>= 37 degrees C). We show here that treatment with 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) prevents this heat-induced sudden death in this mouse model. The protection by AICAR is independent of AMP-activated protein kinase (AMPK) activation and results from a newly identified action of the compound on mutant Ryr1 to reduce Ca2+ leak from the sarcoplasmic reticulum to the sarcoplasm. AICAR thus prevents Ca2+-dependent increases in the amount of both reactive oxygen species (ROS) and reactive nitrogen species (RNS) that act to further increase resting Ca2+ concentrations. If unchecked, the temperature-driven increases in resting Ca2+ concentrations and the amounts of ROS and RNS create an amplifying cycle that ultimately triggers sustained muscle contractions, rhabdomyolysis and death. Although antioxidants are effective in reducing this cycle in vitro, only AICAR prevents heat-induced death in vivo. Our findings suggest that AICAR is probably effective in prophylactic treatment of humans with enhanced susceptibility to exercise- and/or heat-induced sudden death associated with RYR1 mutations.

AB The 15 known Fanconi anemia proteins cooperate in a pathway that regulates DNA interstrand cross-link repair. Recent studies indicate that the Fanconi anemia pathway also controls Rev1-mediated translesion DNA synthesis (Us). We identified Fanconi anemia associated protein (FAAP20), an integral subunit of the multisubunit Fanconi anemia core complex. FAAP20 binds to FANCA subunit and is required for stability of the complex and monoubiquitination of FANCD2. FAAP20 contains a ubiquitin-binding zinc finger 4 domain and binds to the monoubiquitinated form of Rev1. FAAP20 binding stabilizes Rev1 nuclear foci and promotes interaction of the Fanconi anemia core with PCNA Rev1 DNA damage bypass complexes. FAAP20 therefore provides a critical link between the Fanconi anemia pathway and Us polymerase activity. We propose that the Fanconi anemia core complex regulates cross-link repair by channeling lesions to damage bypass pathways and preventing large DNA insertions and deletions.

AB Processivity, the ability of single molecules to move continuously along a track, is a fundamental requirement of cargo-transporting molecular motors. Here, we investigate how cytoplasmic dynein, a homodimeric, microtubule-based motor, achieves processive motion. To do this, we developed a versatile method for assembling Saccharomyces cerevisiae dynein heterodimers, using complementary DNA oligonucleotides covalently linked to dynein monomers labeled with different organic fluorophores. Using two-color, single-molecule microscopy and high-precision, two-dimensional tracking, we find that dynein has a highly variable stepping pattern that is distinct from all other processive cytoskeletal motors, which use 'hand-over-hand' mechanisms. Uniquely, dynein stepping is stochastic when its two motor domains are close together. However, coordination emerges as the distance between motor domains increases, implying that a tension-based mechanism governs these steps. This plasticity may allow tuning of dynein for it diverse cellular functions.

AB Veterans comprise a large and growing segment of the US population. Results from national telephone surveys suggest higher prevalence of overweight among Veterans compared with demographically similar non-Veterans, based on self-reported height and weight. Using 1999-2008 data from the National Health and Nutrition Examination Survey (NHANES), we compared 3,768 Veterans and 21,974 non-Veterans on: (i) several measures of adiposity based on direct anthropometry; (ii) life-course of self-reported BMI; and (iii) behaviors related to weight loss or maintenance. Whether Veterans were more likely than demographically similar non-Veterans to be obese or overweight depended on the adiposity measure employed. On BMI, Veterans were about equally likely to be obese (30+ kg/m(2)), but more likely to be overweight (25-29.9 kg/m(2)) by both self-report and by direct measurement (significantly so only by self-report). On waist-stature ratio, a roughly similar pattern was observed. On waist circumference, Veterans tended to have larger values than demographically similar non-Veterans, with more Veterans in the largest two categories. But on dual-photon X-ray absorptiometry, Veterans were less likely to have 35+% body fat than non-Veterans of similar age, gender, and race/ethnicity. Life-course trends in self-reported BMI suggested a possible burst of weight gain after military discharge. These results suggest that Veterans may, on average, have less excess body fat than non-Veterans-a pattern not revealed by standard anthropometric measures.

TI Obesity Paradox in Amputation Risk Among Nonelderly Diabetic Men
SO OBESITY
LA English
DT Article
ID VASCULAR COMPLICATIONS; OVERWEIGHT
AB The association between BMI and amputation risk is not currently well known. We used data for a cohort of diabetic patients treated in the US Department of Veterans Affairs Healthcare System in 2003. Men aged <65 years at the end of follow-up were examined for their amputation risk and amputation-free survival during the next 5 years (2004-2008). Compared to overweight individuals (BMI 25-29.9 kg/m(2)), the risks of amputation and treatment failure (amputation or death) were higher for patients with BMI <25 kg/m(2) and were lower for those with BMI >= 30kg/m(2). Individuals with BMI kg/m(2) were only half as likely to experience any (hazard ratios (HR) = 0.49; 95% confidence interval (Cl), 0.30-0.80) and major amputations (HR = 0.53; 95% CI, 0.39-0.73) during follow-up as overweight individuals. While the amputation risk continued to decrease for higher BMI, amputation-free survival showed a slight upturn at BMI >40 kg/m(2). The association between obesity and amputation risk in our data shows a pattern consistent with "obesity paradox" observed in many health conditions. More research is needed to better understand pathophysiological mechanisms that may explain the paradoxical association between obesity and lower-extremity amputation (LEA) risk.

AB Reitmair A, Sachs G, Im WB, Wheeler L. C6orf176: a novel possible regulator of cAMP-mediated gene expression. Physiol Genomics 44: 152-161, 2012. First published November 22, 2011; doi:10.1152/physiolgenomics.00089.2011.-cAMP mediates diverse cellular signals including prostaglandin (PG) E-2-mediated intraocular pressure (IOP)-lowering activity in human ocular ciliary smooth muscle cells (hCSM). We have identified gene regulatory networks and key genes upon activation of the cAMP pathway in hCSM, using novel agonists highly selective for PGE(2) receptor subtypes EP2 or EP4, which are G protein-coupled receptors well known to activate cAMP signaling. Here we describe a novel, EP2/EP4-induced, primate-specific gene of hitherto unknown function, also known as C6orf176 (chromosome 6 open reading frame 176) and recently reclassified as noncoding RNA in NCBI's database. Its expression, as determined by quantitative real-time RT-PCR (qRT-PCR), is dramatically upregulated (>2,000-fold) subsequent to transduction of EP2/EP4/Gs/cAMP signaling not only in hCSM, but also in HEK cells overexpressing the recombinant receptors. Moreover, activation of other IOP lowering, Gs-coupled prostanoid receptors, such as DP1 and IP, as well as a direct activator of adenylyl cyclase, forskolin, also substantially upregulated C6orf176 in hCSM, while FP and TP, which are Gq-coupled prostanoid receptor subtypes, did not. Novel transcript variants carrying open reading frames, derived from an at least 67 kb genomic locus on chromosome 6q27 with putative alternative transcription start sites, were identified. Transcriptional upregulation of transcript variants as well as of two genes expressed in antisense orientation that partially overlap the transcribed C6orf176 region was observed, to varying degrees, subsequent to induction of cAMP signaling using various agonists. Small interfering RNA-mediated C6orf176 gene silencing experiments showed modulation of several cAMP-responsive genes. These transcriptional activities identify C6orf176 as a potential biomarker and/or therapeutic target in context with diseases linked to deregulated cAMP signaling. Also, the cAMP-inducible C6orf176 gene locus could be useful as a model system for studying transcriptional regulation by chromatin and RNA polymerase II.

AB Background. Previous studies have suggested that motivational aspects of executive functioning, which may be disrupted in schizophrenia patients with negative symptoms, are mediated in part by the striatum. Negative symptoms have been linked to impaired recruitment of both the striatum and the dorsolateral prefrontal cortex (DLPFC). Here we tested the hypothesis that negative symptoms are associated primarily with striatal dysfunction, using functional magnetic resonance imaging (fMRI).
Method. Working-memory load-dependent activation and gray matter volumes of the striatum and DLPFC were measured using a region-of-interest (ROI) approach, in 147 schizophrenia patients and 160 healthy controls. In addition to testing for a linear relationships between striatal function and negative symptoms, we chose a second, categorical analytic strategy in which we compared three demographically and behaviorally matched subgroups: patients with a high burden of negative symptoms, patients with minimal negative symptoms, and healthy subjects.
Results. There were no differences in striatal response magnitudes between schizophrenia patients and healthy controls, but right DLPFC activity was higher in patients than in controls. Negative symptoms were inversely associated with striatal, but not DLPFC, activity. In addition, patients with a high burden of negative symptoms exhibited significantly lower bilateral striatal, but not DLPFC, activation than schizophrenia patients with minimal negative symptoms. Working memory performance, antipsychotic exposure and changes in gray matter volumes did not account for these differences.
Conclusions. These data provide further evidence for a robust association between negative symptoms and diminished striatal activity. Future work will determine whether low striatal activity in schizophrenia patients could serve as a reliable biomarker for negative symptoms.

AB Objectives: Acute lung injury (ALI) can develop during the course of many clinical conditions, and is associated with significant morbidity and mortality. Valproic acid (VPA), a well-known anti-epileptic drug, has been shown to have anti-oxidant and anti-inflammatory effects in various ischemia/reperfusion (I/R) models. The purpose of this study was to investigate whether VPA could affect survival and development of ALI in a rat model of intestinal I/R.
Methods: Two experiments were performed. Experiment I: Male Sprague-Dawley rats (250-300 g) were subjected to intestinal ischemia (1 h) and reperfusion (3 h). They were randomized into 2 groups (n = 7 per group) 30 min after ischemia: Vehicle (Veh) and VPA (300 mg/kg, IV). Primary end-point for this study was survival over 4 h from the start of ischemia. Experiment II: The histological and biochemical effects of VPA treatment on lungs were examined 3 h (1 h ischemia + 2 h reperfusion) after intestinal I/R injury (Veh vs. VPA, n = 9 per group). An objective histological score was used to grade the degree of ALI. Enzyme linked immunosorbent assay (ELISA) was performed to measure serum levels of interleukins (IL-6 and 10), and lung tissue of cytokine-induced neutrophil chemoattractant (CINC) and myeloperoxidase (MPO). In addition, the activity of 8-isoprostane was analyzed for pulmonary oxidative damage.
Results: In Experiment I, 4-h survival rate was significantly higher in VPA treated animals compared to Veh animals (71.4% vs. 14.3%, p = 0.006). In Experiment II, ALI was apparent in all of the Veh group animals. Treatment with VPA prevented the development of ALI, with a reduction in the histological score (3.4 +/- 0.3 vs. 5.3 +/- 0.6, p = 0.025). Moreover, compared to the Veh control group the animals from the VPA group displayed decreased serum levels of IL-6 (952 +/- 213 pg/ml vs. 7709 +/- 1990 pg/ml, p = 0.011), and lung tissue concentrations of CINC (1188 +/- 28 pg/ml vs. 1298 +/- 27 pg/ml, p < 0.05), MPO activity (368 +/- 23 ng/ml vs. 490 +/- 29 ng/ml, p < 0.05) and 8-isoprostane levels (1495 +/- 221 pg/ml vs. 2191 +/- 177 pg/ml, p < 0.05).
Conclusion: VPA treatment improves survival and attenuates ALI in a rat model of intestinal I/R injury, at least in part, through its anti-oxidant and anti-inflammatory effects. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB Background and Purpose-The implementation of uniform nomenclature and classification in adult arterial ischemic stroke (AIS) has been critical for defining outcomes and recurrence risks according to etiology and in developing risk-stratified treatments. In contrast, current classification and nomenclature in childhood AIS are often overlapping or contradictory. Our purpose was to develop a comprehensive consensus-based classification system for childhood AIS.
Methods-Using a modified-Delphi method, members of the International Pediatric Stroke Study (IPSS) developed the Childhood AIS Standardized Classification And Diagnostic Evaluation (CASCADE) criteria. Two groups of pediatric stroke specialists from the IPSS classified 7 test cases using 2 methods each: (1) classification typical of the individual clinician's current clinical practice; and (2) classification based on the CASCADE criteria. Group 1 underwent in-person training in the utilization of the CASCADE criteria. Group 2 classified the same cases via an online survey, including definitions but without training. Inter-rater reliability (IRR) was assessed via multi-rater unweighted kappa-statistic.
Results-In Group 1 (with training), IRR was improved using CASCADE criteria (kappa=0.78, 95% CI=[0.49, 0.94]), compared with typical clinical practice (kappa=0.40, 95% CI= [0.11, 0.60]). In Group 2 (without training), IRR was lower than among trained raters (kappa=0.61, 95% CI= [0.29, 0.77]), but higher than current practice (kappa=0.23, 95% CI= [0.03, 0.36]).
Conclusions-A new, consensus-based classification system for childhood AIS, the CASCADE criteria, can be used to classify cases with good IRR. These preliminary findings suggest that the CASCADE criteria may be particularity useful in the setting of prospective multicenter studies in childhood-onset AIS, where standardized training of investigators is feasible.

AB Background and Purpose-Elevated serum levels of brain natriuretic peptide (BNP) have been associated with cardioembolic stroke and increased poststroke mortality. We sought to determine whether BNP levels were associated with functional outcome after ischemic stroke.
Methods-We measured BNP in consecutive patients aged years admitted to our stroke unit between 2002 to 2005. BNP quintiles were used for analysis. Stroke subtypes were assigned using Trial of ORG 10172 in Acute Stroke Treatment criteria. Outcomes were measured as 6-month modified Rankin Scale score ("good outcome"=0-2 versus "poor") as well as mortality. Multivariate logistic regression was used to assess association between the quintiles of BNP and outcomes. Predictive performance of BNP as compared with clinical model alone was assessed by comparing receiver operating characteristic curves.
Results-Of 569 patients with ischemic stroke, 46% were female; mean age was 67.9 +/- 15 years. In age- and gender-adjusted analysis, elevated BNP was associated with lower ejection fraction (P<0.0001) and left atrial dilatation (P<0.001). In multivariate analysis, elevated BNP decreased the odds of good functional outcome (OR, 0.64; 95% CI, 0.41-0.98) and increased the odds of death (OR, 1.75; 95% CI, 1.36-2.24) in these patients. Addition of BNP to multivariate models increased their predictive performance for functional outcome (P=0.013) and mortality (P<0.03) after cardioembolic stroke.
Conclusions-Serum BNP levels are strongly associated with cardioembolic stroke and functional outcome at 6 months after ischemic stroke. Inclusion of BNP improved prediction of mortality in patients with cardioembolic stroke. (Stroke. 2012;43:441-445.)

ASTROCYTES
AB Background and Purpose-Traumatic and ischemic brain injury induce plasmalemma permeability and necrosis; however, no studies have examined these aspects of cellular injury in intracerebral hemorrhage models.
Methods-In vivo propidium iodide (PI) and YOYO-1 were used to assess plasmalemma damage after collagenase-induced intracerebral hemorrhage in mice. Ex vivo aspartylglutamylvalylaspartic acid, terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling, and electron microscopy were used to assess the relationship between plasmalemma permeability and mode of cell death. Cell types vulnerable to plasmalemma damage were determined by immunohistochemistry.
Results-Plasma lemma permeability was first detected in the lesion at 1 to 3 hours and peaked at 48 to 72 hours. Neurons and IBA-1-positive cells with morphological features of monocytes were sensitive, whereas resident microglia and astocytes were resistant to plasmalemma permeability. PI+ cells colocalized with fluorescent-labeled caspase substrates and terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling beginning at 3 to 6 hours. At 48 hours, greater than half of injured cells were PI+/aspartylglutamylvalylaspartic acid- or PI+/terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling -suggesting necrosis, and <5% were PI-/terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling+ or PI-/aspartylglutamylvalylaspartic acid+. Electron microscopy confirmed ultrastructural features of necrosis at 24 hours after intracerebral hemorrhage, high mobility group box protein-1 was released from permeable cells, and mice deficient in receptor interacting protein kinase (RIPK) 3, a known necrosis trigger, had 50% less PI+ cells at 24 hours. Permeable cells remained in the brain for at least 24 hours with <10% spontaneous resealing.
Conclusions-Necrosis contributes to cell demise after intracerebral hemorrhage. Programmed necrosis and plasmalemma damage may represent novel therapeutic targets to prevent cell death or rescue injured cells after intracerebral hemorrhage. (Stroke. 2012;43:524-531.)

ID MRI; ISCHEMIA; DWI
AB Background and Purpose-We report on the use of line scan diffusion magnetic resonance imaging in the evaluation of spinal cord infarctions.
Methods-Data on 19 patients with clinical findings consistent with spinal cord infarctions and abnormal findings on line scan diffusion imaging were reviewed. The Apparent Diffusion Coefficient (ADC) measurements for the normal spinal cord and for the areas of abnormality were calculated from trace ADC maps.
Results-Restricted diffusion was found in all 19 patients. Absolute ADC values in the ischemic area ranged between 395.4 and 575.8X10(-6) mm(2)/s, with ADC ratios ranging between 39.4% and 57.4%.
Conclusions-Line scan diffusion imaging is technically feasible and appears to be a reliable method to diagnose spinal cord infarction in the acute setting. (Stroke. 2012;43:532-535.)

AB Background and Purpose-Poststroke hyperglycemia and diabetes mellitus are associated with lower thrombolytic efficacy and an increased risk of postischemic cerebral hemorrhage. We aimed to develop a rodent model of thrombolysis in diabetic stroke that mimics the clinical situation.
Method-Male 6-week Type I diabetic rats (14 weeks old) were subjected to embolic focal stroke and treated with tissue-type plasminogen activator at 1.5 hours. Reperfusion and 24-hour neurological outcomes were measured and compared with nondiabetic control rats.
Results-Diabetic rats exhibited resistance to thrombolytic reperfusion, larger infarction volumes, and increased intracerebral hemorrhage.
Conclusions-This animal model would be relevant to future studies investigating pathophysiological mechanisms and in developing new therapeutic approaches to enhance the efficacy of tissue-type plasminogen activator thrombolysis in stroke patients with diabetes or poststroke hyperglycemia.

AB Thrombus formation is of paramount importance in the pathophysiology of acute ischemic stroke. Current antithrombotics used to treat or prevent cerebral ischemia are only moderately effective or bear an increased risk of severe bleeding. von Willebrand factor (VWF) has long been known to be a key player in thrombus formation at sites of vascular damage. While the association between VWF and coronary heart disease has been well studied, knowledge about the role of VWF in stroke is much more limited. However, in recent years, an increasing amount of clinical and preclinical evidence has revealed the critical involvement of VWF in stroke development. This review summarizes the latest insights into the pathophysiologic role of VWF-related processes in ischemic brain injury under experimental conditions and in humans. Potential clinical merits of novel inhibitors of VWF-mediated platelet adhesion and activation as powerful and safe tools to combat thromboembolic disorders including ischemic stroke are discussed. Preclinical and clinical evidence illustrates an important role of VWF in ischemic stroke, suggesting that VWF could become a promising target in stroke therapy. (Stroke. 2012;43:599-606.)

AB Multiple precursor proteins have been shown to cause cardiac amyloidosis. The most common forms are due either to immuno globulin light chains or to transthyretin proteins (either wild-type or mutant forms). Correct subclassification of the amyloid is paramount because treatment differs in accordance with the type of amyloidosis. Indirect diagnostic methods, including serologic analysis, can lead to misdiagnosis. Definitive diagnosis often requires analysis of amyloid in the tissue. We present a case of a woman who was diagnosed with hereditary transthyretin cardiac amyloidosis by means of immuno fluorescence and genetic analysis. This case highlights the importance in the diagnostic algorithm of cardiac amyloidosis of direct evaluation of the tissue with immuno fluorescence and of genetic testing.

AB Aims Evidence indicates that Alcoholics Anonymous (AA) participation reduces relapse risk but less is known about the mechanisms through which AA confers this benefit. Initial studies indicate self-efficacy, negative affect, adaptive social networks and spiritual practices are mediators of this effect, but because these have been tested in isolation, their relative importance remains elusive. This study tested multiple mediators simultaneously to help determine the most influential pathways. Design Prospective, statistically controlled, naturalistic investigation examined the extent to which these previously identified mechanisms mediated AA attendance effects on alcohol outcomes controlling for baseline outcome values, mediators, treatment, and other confounders. Setting Nine clinical sites within the United States. Participants Adults (n = 1726) suffering from alcohol use disorder (AUD) initially enrolled in a randomized study with two arms: aftercare (n = 774); and out-patient (n = 952) comparing three out-patient treatments (Project MATCH). Measurements AA attendance during treatment; mediators at 9 months; and outcomes [percentage of days abstinent (PDA) and drinks per drinking day (DDD)] at 15 months. Findings Among out-patients the effect of AA attendance on alcohol outcomes was explained primarily by adaptive social network changes and increases in social abstinence self-efficacy. Among more impaired aftercare patients, in addition to mediation through adaptive network changes and increases in social self-efficacy, AA lead to better outcomes through increasing spirituality/religiosity and by reducing negative affect. The degree to which mediators explained the relationship between AA and outcomes ranged from 43% to 67%. Conclusion While Alcoholics Anonymous facilitates recovery by mobilizing several processes simultaneously, it is changes in social factors which appear to be of primary importance.

AB Background: We sought to determine the impact of naltrexone on hepatic enzymes and HIV biomarkers in HIV-infected patients.
Methods: We used data from the Veterans Aging Cohort Study-Virtual Cohort, an electronic database of administrative, pharmacy, and laboratory data. We restricted our sample to HIV-infected patients who received an initial oral naltrexone prescription of at least 7 days duration. We examined aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and HIV biomarker (CD4 and HIV RNA) values for the 365 days prior to, during, and for the 365 days post-naltrexone prescription. We also examined cases of liver enzyme elevation (LEE; defined as > 5 times baseline ALT or AST or > 3.5 times baseline if baseline ALT or AST was > 40 IU/l).
Results: Of 114 HIV-infected individuals, 97% were men, 45% white, 57% Hepatitis C co-infected; median age was 49 years; 89% of the sample had a history of alcohol dependence and 32% had opioid dependence. Median duration of naltrexone prescription was 49 (interquartile range 30 to 83) days, representing 9,525 person-days of naltrexone use. Mean ALT and AST levels remained below the upper limit of normal. Two cases of LEE occurred. Mean CD4 count remained stable and mean HIV RNA decreased after naltrexone prescription.
Conclusions: In HIV-infected patients, oral naltrexone is rarely associated with clinically significant ALT or AST changes and does not have a negative impact on biologic parameters. Therefore, HIV-infected patients with alcohol or opioid dependence can be treated with naltrexone.

AB PURPOSE: To describe the clinical and microscopic features of pigmented basal cell carcinomas (pBCC) of the eyelid.
DESIGN: Retrospective observational case series collected at one institution.
METHODS: An analysis of clinical records, photographs, and histopathologic characteristics of 257 BCCs with a review of the literature. The frequencies of clinically pigmented, and of microscopically pigmented but clinically nonpigmented, BCCs were determined. Cytochemical stains (Fontana-Masson, Prussian blue) and immunohistochemical probes (S-100, microphthalmia-associated transcription factor [MiTF], HMB-45, MART-1, CK20, synaptophysin, chromogranin, CD1a, Ki-67) were then employed and the findings correlated with the degree of clinical pigmentation.
RESULTS: Histopathologically, 13 of 257 cases (5.06%) were found to have pigment; of these 13, 6 (all white patients) had clinically apparent pigmentation (2.33%), either focal or diffuse. Eight of 13 lesions developed on the lower eyelids. All stained positively for melanin but negatively for iron. MiTF highlighted numerous melanocytic nuclei in the tumor lobules, while MART-1 and HMB-45 revealed the dendritic shapes of the entrapped melanocytes. There was a subtotal blockage of melanin transfer to the surrounding basaloid cells. Intralobular S-100-positive cells included CD1a-positive Langerhans cells, while CK20 did not identify any Merkel cells.
CONCLUSIONS: Only 1 of 6 lesions was uniformly clinically pigmented, whereas the other 5 were only focally brown-black. The clinical pigmentation was imparted by varying densities and distributions of melanocytes with arborizing dendrites, which were present in all BCCs. Melanophages within the stroma and basaloid cell melanization also contributed to pigmentation. No behavioral or biologic differences in pBCC were documented compared with clinically nonpigmented lesions. (Am J Ophthalmol 2012;153:242-252. (C) 2012 by Elsevier Inc. All rights reserved.)

AB Objectives. We sought to determine whether health care use and expenditures among gay and bisexual men were reduced following the enactment of same-sex marriage laws in Massachusetts in 2003.
Methods. We used quasi-experimental, prospective data from 1211 sexual minority male patients in a community-based health center in Massachusetts.
Results. In the 12 months after the legalization of same-sex marriage, sexual minority men had a statistically significant decrease in medical care visits (mean=5.00 vs mean=4.67; P=.05; Cohen's d=0.17), mental health care visits (mean=24.72 vs mean=22.20; P=.03; Cohen's d=0.35), and mental health care costs (mean=$2442.28 vs mean=$2137.38; P=.01; Cohen's d=0.41), compared with the 12 months before the law change. These effects were not modified by partnership status, indicating that the health effect of same-sex marriage laws was similar for partnered and nonpartnered men.
Conclusions. Policies that confer protections to same-sex couples may be effective in reducing health care use and costs among sexual minority men. (Am J Public Health. 2012;102:285-291. doi:10.2105/AJPH.2011.300382)

AB Rationale: Controversy persists regarding the presence and importance of hypoglossal nerve dysfunction in obstructive sleep apnea (OSA).
Objectives: We assessed quantitative parameters related to motor unit potential (MUP) morphology derived from electromyographic (EMG) signals in patients with OSA versus control subjects and hypothesized that signs of neurogenic remodeling would be present in the patients with OSA.
Methods: Participants underwent diagnostic sleep studies to obtain apnea-hypopnea indices. Muscle activity was detected with 50-mm concentric needle electrodes. The concentric needle was positioned at more than 10 independent sites per subject, after the local anatomy of the upper airway musculature was examined by ultrasonography. All activity was quantified with subjects awake, during supine eupneic breathing while wearing a nasal mask connected to a pneumotachograph. Genioglossus EMG signals were analyzed offline by automated software (DQEMG), which extracted motor unit potential trains (MUPTs) contributed by individual motor units from the composite EMG signals. Quantitative measurements of MUP templates, including duration, peak-to-peak amplitude, area, area-to-amplitude ratio, and size index, were compared between the untreated patients with OSA and healthy control subjects.
Measurements and Main Results: A total of 1,655 MUPTs from patients with OSA (n = 17; AH I, 55 +/- 6/h) and control subjects (n = 14; AHI, 4 +/- 1/h) were extracted from the genioglossus muscle EMG signals. MUP peak-to-peak amplitudes in the patients with OSA were not different compared with the control subjects (397.5 +/- 9.0 vs. 382.5 +/- 10.0 mu V). However, the MUPs of the patients with OSA were longer in duration (11.5 +/- 0.1 vs. 10.3 +/- 0.1 ms; P < 0.001) and had a larger size index (4.09 +/- 0.02 vs. 3.92 +/- 0.02; P < 0.001) compared with control subjects.
Conclusions: These results confirm and quantify the extent and existence of structural neural remodeling in OSA.

AB Background: Although lateral retinacular release (LR) surgery has historically been one of the most commonly used arthroscopic procedures for the treatment of patellar instability and anterior knee pain, it may be associated with complications and poor functional outcome measures.
Purpose: To examine the clinical efficacy of open lateral retinacular closure (LRC), a novel but technically simple procedure in the treatment of disabling anterolateral knee pain, tenderness, and positive medial patellar apprehension testing in patients who have undergone prior arthroscopic LR surgery.
Study Design: Case series; Level of evidence, 4.
Methods: The records of 22 patients who had previously undergone an arthroscopic LR and underwent a diagnostic arthroscopy and LRC were reviewed. Physical examination findings and symptoms after prior LR surgery, duration between LR and LRC surgeries, and arthroscopic findings immediately before LRC were analyzed. Preoperative and postoperative Lysholm knee scores and activity levels were compared, and subjective satisfaction ratings assessed.
Results: Average follow-up after LRC was 3.2 years. Mean preoperative Lysholm knee score was 46.5 (range, 25-90), which improved postoperatively to a mean score of 86 (range, 48-100). Fourteen percent of patients subjectively rated their preoperative function as fair and 86% as poor. Postoperatively, 82% rated themselves as good or excellent and 18% as fair, with all patients improving from the LRC procedure. All patients stated that they would have the procedure again for the same problem.
Conclusion: Open LRC provides significant pain relief and improvement in functional knee outcome scores in patients with persistent pain and tenderness at the site of a previous lateral release and a positive medial patellar apprehension test. Lateral release procedures should be considered with caution. For patients with anterolateral knee pain and symptoms of medial patellar instability after lateral release, LRC may provide symptomatic relief and functional improvement.

AB End-stage lung disease is a major health care challenge. Lung transplantation remains the definitive treatment, yet rejection and donor organ shortage limit its broader clinical impact. Engineering bioartificial lung grafts from patient-derived cells could theoretically lead to alternative treatment strategies. Although many challenges on the way to clinical application remain, important early milestones toward translation have been met. Key endodermal progenitors can be derived from patients and expanded in vitro. Advanced culture conditions facilitate the formation of three-dimensional functional tissues from lineage-committed cells. Bioartificial grafts that provide gas exchange have been generated and transplanted into animal models. Looking ahead, current challenges in bioartificial lung engineering include creation of ideal scaffold materials, differentiation and expansion of lung-specific cell populations and full maturation of engineered constructs to provide graft longevity after implantation in vivo. A multidisciplinary collaborative effort will not only bring us closer to the ultimate goal of engineering patient-derived lung grafts, but also generate a series of clinically valuable translational milestones such as airway grafts and disease models. This review summarizes achievements to date, current challenges and ongoing research in bioartificial lung engineering.

AB Chronic allograft vasculopathy (CAV) in murine heart allografts can be elicited by adoptive transfer of donor specific antibody (DSA) to class I MHC antigens and is independent of complement. Here we address the mechanism by which DSA causes CAV. B6.RAG1-/- or B6.RAG1-/-C3-/- (H-2b) mice received B10.BR (H-2k) heart allografts and repeated doses of IgG2a, IgG1 or F(ab)2 fragments of IgG2a DSA (anti-H-2k). Intact DSA regularly elicited markedly stenotic CAV in recipients over 28 days. In contrast, depletion of NK cells with anti-NK1.1 reduced significantly DSA-induced CAV, as judged morphometrically. Recipients genetically deficient in mature NK cells (?-chain knock out) also showed decreased severity of DSA-induced CAV. Direct NK reactivity to the graft was not necessary. F(ab)2 DSA fragments, even at doses twofold higher than intact DSA, were inactive. Graft microvascular endothelial cells responded to DSA in vivo by increased expression of phospho-extracellular signal-regulated kinase (pERK), a response not elicited by F(ab)2 DSA. We conclude that antibody mediates CAV through NK cells, by an Fc dependent manner. This new pathway adds to the possible mechanisms of chronic rejection and may relate to the recently described C4d-negative chronic antibody-mediated rejection in humans.

AB The presence of alloreactive memory T cells is a major barrier for induction of tolerance in primates. In theory, delaying conditioning for tolerance induction until after organ transplantation could further decrease the efficacy of the regimen, since preexisting alloreactive memory T cells might be stimulated by the transplanted organ. Here, we show that such delayed tolerance can be induced in nonhuman primates through the mixed chimerism approach, if specific modifications to overcome/avoid donor-specific memory T-cell responses are provided. These modifications include adequate depletion of CD8+ memory T cells and timing of donor bone marrow administration to minimize levels of proinflammatory cytokines. Using this modified approach, mixed chimerism was induced successfully in 11 of 13 recipients of previously placed renal allografts and long-term survival without immunosuppression could be achieved in at least 6 of these 11 animals.

AB SOD1, ANG, TARDBP and FUS mutations have been associated with amyotrophic lateral sclerosis (ALS). Our goal was to extend molecular genetic analysis to newly identified ALS genetic loci and to determine the frequency of mutations, distribution of disease genes, and variant spectrum of these genes in a large United States ALS-phenotype cohort. We screened 1220 probands with an ALS phenotype, referred originally for SOD1 molecular genetic analysis. 1128 SOD1-negative probands were screened for ANG, and 277 and 223 SOD1- and ANG-negative samples were screened for TARDBP and FUS, respectively. One hundred additional probands were specifically screened only for FUS exon 15. We identified a total of 36 different SOD1 mutations, including three novel mutations, in 92 probands. ANG screening identified three mutations, including two novel mutations, and TARDBP screening identified two previously reported TARDBP mutations. We also identified four mutations in FUS, including the reported FUS in-frame deletion, c.430_447del, p.Gly144_Tyr149del, in a patient with inclusion body myositis, and two known FUS missense mutations. From this study, we estimate frequencies for SOD1, ANG, TARDBP and FUS mutations, in this United States cohort, to be 7.5%, 0.71%, 0.72% and 1.9%, respectively. In conclusion, we identify novel variants in SOD1, ANG, TARDBP and FUS, and expand the FUS-associated clinicopathologic phenotype.

AB BACKGROUND: The etiology of postoperative cognitive decline (POCD) remains to be determined. Anesthetic isoflurane, but not desflurane, may induce neurotoxicity. However, the functional consequences of these effects have not been assessed. We therefore performed a pilot study to determine the effects of isoflurane and desflurane on cognitive function in humans.
METHODS: The subjects included patients who had lower extremity or abdominal surgery under spinal anesthesia alone (S, n = 15), spinal plus desflurane anesthesia (SD, n = 15), or spinal plus isoflurane anesthesia (SI, n = 15) by randomization. Each of the subjects received cognitive tests immediately before and 1 week after anesthesia and surgery administered by an investigator who was blinded to the anesthesia regimen. POCD was defined using the scores from each of these tests.
RESULTS: We studied 45 subjects, 24 males and 21 females. The mean age of the subjects was 69.0 +/- 1.9 years. There was no significant difference in age and other characteristics among the treatment arms. The mean number of cognitive function declines in the S, SD, and SI groups was 1.13, 1.07, and 1.40, respectively. POCD incidence after SI (27%), but not SD (0%), anesthesia was higher than that after S (0%), P = 0.028 (3-way comparison).
CONCLUSION: These findings from our pilot study suggest that isoflurane and desflurane may have different effects on postoperative cognitive function, and additional studies with a larger sample size and longer times of follow-up testing are needed. (Anesth Analg 2012;114:410-5)

AB Background: Subarachnoid hemorrhage (SAH) in pregnancy occurs because of a variety of etiologies, which range from ruptured aneurysms to benign venous bleeding. The more malignant etiologies represent an important cause of maternal morbidity and mortality. We sought to investigate the epidemiology and mechanisms of pregnancy-related SAH.
Methods: Using the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, we extracted pregnancy-related admissions for women ages 15-44 from 1995-2008 and identified admissions complicated by SAH. Logistic regression identified independent predictors of SAH. Outcomes and risk factors were then compared with age-matched, nonpregnant women with SAH. We also analyzed our institution's experience with pregnancy-related SAH.
Results: There were 639 cases (5.8 per 100,000 deliveries) of pregnancy-related SAH in the cohort during the study period; SAH was associated with 4.1% of all pregnancy-related in-hospital deaths. More than half of the SAH cases occurred postpartum. Advancing age, African-American race, Hispanic ethnicity, hypertensive disorders: coagulopathy, tobacco, drug or alcohol abuse, intracranial venous thrombosis, sickle cell disease, and hypercoagulability were independent risk factors for pregnancy-related SAH. Compared with SAH in nonpregnant controls, pregnancy-related SAH had lower clipping/coiling rates (12.7% vs. 44.5%, P < 0.001). We identified 12 cases of pregnancy-related SAH in our hospital, the majority of which presented postpartum and with severe headache.
Conclusion: SAN during pregnancy results from a range of etiologies, and is less likely to be because of a cerebral aneurysm than SAH occurring in the nonpregnant patient. Peripartum SAH frequently occurs in the setting of hypertensive disorders.

AB Over the last 35 years, classical CMF (combination chemotherapy with cyclophosphamide, methotrexate and fluorouracil) has been a milestone in the adjuvant treatment of women with breast cancer. However, after an early burst of success lasted just over 10 years, classical CMF has been supplanted by 'third-generation' regimens containing taxanes and anthracyclines. Questions have been raised in the past years concerning the true effectiveness of adjuvant CMF for specific subgroups of patients and particularly, recent retrospective data support the fact that the CMF might have a role in the treatment of patients with triple-negative breast cancer. One possible justification for supporting this role of CMF may be sought in the mechanism of action of drugs used in the regimen, as triple-negative cells may be sensitive to alkylating agents that cause double-strand breaks in DNA. The lesson learned from the CMF could lead us to identify new combinations of drugs that could include the optimal chemotherapy backbone for triple-negative breast cancer such as platinum compounds or alkylating agents or Poly (ADP-ribose) polymerase inhibitors. In conclusion, although we have learned a lot from the use of CMF, many questions are still open and hopefully stimulate our thinking, as clinicians, leading us to find new and more effective ways to treat breast cancer.

AB Background: E2104 was designed to evaluate the safety of two different strategies incorporating bevacizumab into anthracycline-containing adjuvant therapy as a precursor to a definitive randomized phase III trial.
Patients and methods: Patients were sequentially assigned to one of two treatment arms. In addition to dose-dense doxorubicin and cyclophosphamide followed by paclitaxel (Taxol) (ddAC -> T), all patients receivedbevacizumab (10 mg/kg every 2 weeks x 26) initiated either concurrently with AC (Arm A: ddBAC -> BT -> B) or with paclitaxel (Arm B: ddAC -> BT -> B). The primary end point was incidence of clinically apparent cardiac dysfunction (CHF).
Results: Patients enrolled were 226 in number (Arm A 104, Arm B 122). Grade 3 hypertension, thrombosis, proteinuria and hemorrhage were reported for 12, 2, 2 and <1% of patients, respectively. Two patients developed grade 3 or more cerebrovascular ischemia. Three patients in each arm developed CHF. There was no significant difference between arms in the proportion of patients with an absolute decrease in left ventricular ejection fraction of >15% or >10% to below the lower limit of normal post AC or post bevacizumab.
Conclusions: Incorporation of bevacizumab into anthracycline-containing adjuvant therapy does not result in prohibitive cardiac toxicity. The definitive phase III trial (E5103) was activated with systematic and extensive cardiac monitoring to define the true impact of bevacizumab on cardiac function.

AB Consensus guidelines recommend neoadjuvant therapy in locally advanced esophageal cancer; however, whether this recommendation has been widely adopted is unknown. Therefore, we evaluated the utilization of neoadjuvant therapy in esophageal cancer and its association with outcomes in the United States.
From the National Cancer Data Base all patients with middle and lower third clinical stage I-III esophageal cancers who underwent surgical resection were identified (1998-2007). Multivariable regression models were developed to identify predictors of neoadjuvant therapy use and associated outcomes.
We identified 8562 patients who underwent surgical resection for esophageal cancer. In nonmetastatic locally advanced tumors, neoadjuvant therapy use increased (stage II 47.9% to 72.5%; stage III 51.0% to 90.1%; P < 0.001). On multivariable analysis, factors associated with the decreased use of neoadjuvant therapy for stage II and III disease were age a parts per thousand yen75 years, Medicare insurance coverage, Charlson score a parts per thousand yen2, stage II (vs. III) disease, and geographic region. Patients with stage II and III disease who underwent neoadjuvant therapy had a lower risk of positive lymph nodes (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.35-0.55) and positive surgical margins (OR 0.51, 95% CI 0.38-0.69). Thirty-day postoperative mortality rates were not significantly affected by neoadjuvant therapy (OR 0.90, 95% CI 0.66-1.24). A pathologic complete response was observed in 10.8% of patients. The only factor that was predictive of pathologic complete response was squamous cell tumor histology (OR 2.14, 95% CI 1.52-3.02).
In surgically treated patients, the use of neoadjuvant trimodal therapy has increased in the past decade; however, opportunities exist to improve adherence to national guidelines.

TI Aortic Dilatation With Bicuspid Aortic Valves: Cusp Fusion Correlates to

AB Background. Congenital bicuspid aortic valves (BAVs) result from fusion of 2 valve cusps, resulting in left-noncoronary (L-N), right-left (R-L), and right-noncoronary (R-N) morphologic presentations. BAVs predispose to ascending thoracic aortic aneurysms (ATAAs). This study hypothesized that ATAAs with each BAV morphologic group possess unique signatures of matrix metalloproteinases (MMPs) and endogenous tissue inhibitors of metalloproteinases (TIMPs).
Methods. Ascending thoracic aortic aneurysm tissue from 46 patients with BAVs was examined for MMP/TIMP abundance, and global MMP activity was compared with normal aortic specimens (n = 15). Proteolytic balance was calculated as the ratio of MMP abundance to a composite TIMP score. Results were stratified by valve morphologic group (L-N [n = 6], R-L [n = 31], and R-N [n = 9]).
Results. The BAV specimens (p < 0.05 versus normal aorta, 100%) displayed elevated global MMP activity (273% +/- 63%), MMP-9 (263% +/- 47%), and decreased MMP-7 (56% +/- 10%), MMP-8 (58% +/- 11%), TIMP-1 (63% +/- 7%), and TIMP-4 (38% +/- 3%). The R-L group showed increased global MMP activity (286% +/- 89%) and MMP-9 (267% +/- 55%) with reduced MMP-7 (45% +/- 7%), MMP-8 (68% +/- 15%), TIMP-1 (58% +/- 7%), and TIMP-4 (35% +/- 3%). The L-N group showed elevated global MMP activity (284% +/- 71%) and decreased MMP-8 (37% +/- 17%) and TIMP-4 (48% +/- 14) activity. In the R-N group, MMP-7 (46% +/- 13%) and MMP-8 (36% +/- 17%) and TIMP-1 (59% +/- 10%) and TIMP-4 (42% +/- 5%) were decreased. The R-L group demonstrated an increased proteolytic balance for MMP-1, MMP-9, and MMP-12 relative to L-N and R-N.
Conclusions. Each BAV morphologic group possesses a unique signature of MMPs and TIMPs. MMP/TIMP score ratios suggest that the R-L group may be more aggressive, justifying earlier surgical intervention. (Ann Thorac Surg 2012;93:457-64) (C) 2012 by The Society of Thoracic Surgeons

TI PmrB Mutations Promote Polymyxin Resistance of Pseudomonas aeruginosa

AB Pseudomonas aeruginosa can develop resistance to polymyxin and other cationic antimicrobial peptides. Previous work has shown that mutations in the PmrAB and PhoPQ regulatory systems can confer low to moderate levels of colistin (polymyxin E) resistance in laboratory strains and clinical isolates of this organism (MICs of 8 to 64 mg/liter). To explore the role of PmrAB in high-level clinical polymyxin resistance, P. aeruginosa isolates from chronically colistin-treated cystic fibrosis patients, most with colistin MICs of >512 mg/liter, were analyzed. These cystic fibrosis isolates contained probable gain-of-function pmrB alleles that conferred polymyxin resistance to strains with a wild-type or pmrAB deletion background. Double mutant pmrB alleles that contained mutations in both the periplasmic and dimerization-phosphotransferase domains markedly augmented polymyxin resistance. Expression of mutant pmrB alleles induced transcription from the promoter of the arnB operon and stimulated addition of 4-amino-L-arabinose to lipid A, consistent with the known role of this lipid A modification in polymyxin resistance. For some highly polymyxin-resistant clinical isolates, repeated passage without antibiotic selection pressure resulted in loss of resistance, suggesting that secondary suppressors occur at a relatively high frequency and account for the instability of this phenotype. These results indicate that pmrB gain-of-function mutations can contribute to high-level polymyxin resistance in clinical strains of P. aeruginosa.

AB Objective To assess a generic measure of health-related quality of life (HRQOL) as an outcome measure in granulomatosis with polyangiitis (Wegener's) (GPA).
Methods. Subjects were participants in the Wegener's Granulomatosis Etanercept Trial (WGET) or the Vasculitis Clinical Research Consortium Longitudinal Study (VCRC-LS). HRQOL was assessed with the Short Form 36 (SF-36) health survey that includes physical and mental component summary scores (PCS and MCS, respectively). Disease activity was assessed with the Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG).
Results. The data from 180 subjects in the WGET (median followup 2.3 years, mean number of visits 10) and 237 subjects in the VCRC-LS (median followup 2.0 years, mean number of visits 8) were analyzed. A 1 unit increase in the BVAS/ WG corresponded to a 1.15 unit (95% confidence interval [ 95% CI] 1.02, 1.29) decrease for the PCS and a 0.93 (95% CI 0.78, 1.07) decrease for the MCS in the WGET, and to a 1.16 unit decrease for the PCS (95% CI 0.94, 1.39) and a 0.79 unit decrease for the MCS (95% CI 0.51, 1.39) in the VCRC-LS. In both arms of the WGET study, SF-36 measures improved rapidly during the first 6 weeks of treatment followed by gradual improvement among patients achieving sustained remission (0.5 improvement in PCS per 3 months), but worsened slightly (0.03 decrease in PCS every 3 months) among patients not achieving sustained remission (P = 0.005).
Conclusion. HRQOL, as measured by the SF-36, is reduced among patients with GPA. SF-36 measures are modestly associated with other disease outcomes and discriminate between disease states of importance in GPA.

AB The insulin-like growth factors (IGF) evolved in lower animals to enable a wide range of physiologic processes, including smell, food consumption, metabolism, growth, reproduction, and dormancy. These functions were accomplished by the actions of multiple related ligands that activated a common transmembrane receptor protein. In higher organisms, including mammals, the insulin and IGF ligands and their receptors evolved to function in a more circumscribed fashion. The contemporary model assigns IGFs as central regulators of cell proliferation, survival, and organism growth, whereas insulin's action dominates at the level of regulation of fuel accumulation, storage, and energy expenditure. Such a simplistic paradigm, however, obscures the fact that insulin and IGF-1 continue to exert overlapping roles in several physiologic processes. Indeed, recent studies have identified previously, unappreciated skeletal actions of insulin, which suggests that insulin-responsive bone cells participate in the regulation of global energy homeostasis. These findings raise intriguing questions on the nature of the fuel sensing and processing mechanisms in bone and their relative importance to overall energy homeostasis in mammals. Answers to these questions should ultimately improve the ability to diagnose and manage patients with metabolic diseases such as diabetes and osteoporosis.

AB Lightweight ambulatory oxygen devices are provided on the assumptions that they enhance compliance and increase activity, but data to support these assumptions are lacking. We studied 22 patients with severe chronic obstructive pulmonary disease receiving long-term oxygen therapy (14 men, average age = 66.9 y, FEV1 = 33.6% pred, PaO2 at rest = 51.7 torr) who were using E-cylinders as their portable oxygen. Subjects were recruited at 5 sites and studied over a 2-week baseline period and for 6 months after randomizing them to either continuing to use 22-lb E-cylinders towed on a cart or to carrying 3.6-lb aluminum cylinders. Utilizing novel electronic devices, ambulatory and stationary oxygen use was monitored continuously over the 2 weeks prior to and the 6 months following randomization. Subjects wore tri-axial accelerometers to monitor physical activity during waking hours for 2-3 weeks prior to, and at 3 and 6 months after, randomization. Seventeen subjects completed the study. At baseline, subjects used 17.2 hours of stationary and 2.5 hours of ambulatory oxygen daily. At 6 months, ambulatory oxygen use was 1.4 +/- 1.0 hrs in those randomized to E-cylinders and 1.9 +/- 2.4 hrs in those using lightweight oxygen (P = NS). Activity monitoring revealed low activity levels prior to randomization and no significant increase over time in either group. In this group of severe chronic obstructive pulmonary disease patients, providing lightweight ambulatory oxygen did not increase either oxygen use or activity. Future efforts might focus on strategies to encourage oxygen use and enhance activity in this patient group. This trial is registered at ClinicalTrials.gov (NCT003257540).

AB Brain metastases are one of the most common neurologic complications of cancer. The incidence is 9%-17% based on various studies, although the exact incidence is thought to be higher. The incidence is increasing with the availability of improved imaging techniques which aid early diagnosis, and effective systemic treatment regimens which prolong life, thus allowing cancer to disseminate to the brain. Lung cancer, breast cancer, and melanoma are the most frequent to develop brain metastases, and account for 67%-80% of all cancers. Most patients with brain metastases have synchronous extracerebral metastases. Some patients present with no known primary cancer diagnosis. In children, brain metastases are rare; germ cell tumors, sarcomas, and neuroblastoma are the common offenders.

AB Purpose of review
This review provides a comprehensive overview of the management of acute stroke within the framework of telestroke services.
Recent findings
The remote neurological examination using high quality videoconferencing coupled with remote review of neuroimaging has gained acceptance and proved its reliability in various publications. Telestroke networks confirmed the safety and efficiency of telethrombolysis, with an increase in the rate of thrombolysis in recent years. The analysis of a telestroke network in Europe showed improved outcomes in a cohort of ischemic stroke patients.
Summary
At the beginning of the millennium, telestroke networks started to develop. Ten years later, there is a collection of about 40 various networks in North America and Europe performing teleconsultations on a regular basis. Telestroke is not a new therapeutic modality, but rather a set of tools to enable more efficient delivery of acute stroke care and to improve the quality of stroke care in neurologically underserved areas. Depending on the level of available regional resources, telestroke networks can support affiliated hospitals by implementing measures that improve the quality of stroke management such as regional campaigns, stroke units and stroke teams, medical education and programs encouraging the usage of guidelines.

DE In vivo flow cytometry (IVFC); in vivo confocal microscopy; circulating

AB Adult zebrafish are being increasingly used as a model in cancer and stem cell research. Here we describe an integrated optical system that combines a laser scanning confocal microscope (LSCM) and an in vivo flow cytometer (IVFC) for simultaneous visualization and cell quantification. The system is set up specifically for non-invasive tracking of both stationary and circulating cells in adult zebrafish (casper) that have been engineered to be optically transparent. Confocal imaging in this instrument serves the dual purpose of visualizing fish tissue microstructure and an imaging-based guide to locate a suitable vessel for quantitative analysis of circulating cells by IVFC. We demonstrate initial testing of this novel instrument by imaging the transparent adult zebrafish casper vasculature and tracking circulating cells in CD41-GFP/Gata1-DsRed transgenic fish whose thrombocytes/erythrocytes express the green and red fluorescent proteins. In vivo measurements allow cells to be tracked under physiological conditions in the same fish over time, without drawing blood samples or sacrificing animals. We also discuss the potential applications of this instrument in biomedical research. (C) 2011 International Society for Advancement of Cytometry

ID DIABETES-MELLITUS; MEN; DIAGNOSIS; CHOICE
AB OBJECTIVE-The study objective was to examine the associations among visceral fat (VF), all-cause mortality, and obesity-related mortality.
RESEARCH DESIGN AND METHODS-A total of 733 Japanese Americans were followed for 16.9 years. Hazard ratios (HRs) per interquartile range increase in VF were calculated using time-dependent Cox proportional hazard models censored at age 82 years, with age as the time axis adjusted for sex and smoking.
RESULTS-Higher VF was associated with all-cause mortality (HR 1.39 [95% CI 1.11-1.75] 107 deaths) and obesity-related mortality (1.39 [1.04-1.85], 68 deaths from cardiovascular disease, diabetes, or obesity-related cancer). After further adjustment for waist circumference, VF remained significantly associated with all-cause mortality (1.41 [1.04-1.92]) but not with obesity-related mortality. The associations between mortality and VF were not independent of BMI.
CONCLUSIONS-VF was associated with all-cause mortality and obesity-related mortality in Japanese Americans. VF did not significantly improve mortality risk assessment beyond that of BMI.

AB OBJECTIVE-We tested genetic associations with weight loss and weight regain in the Diabetes Prevention Program, a randomized controlled trial of weight-loss inducing interventions (lifestyle and metformin) versus placebo.
RESEARCH DESIGN AND METHODS-Sixteen obesity-predisposing single nucleotide polymorphisms (SNPs) were tested for association with short-term (baseline to 6 months) and long-term (baseline to 2 years) weight loss and weight regain (6 months to study end).
RESULTS-Irrespective of treatment, the Ala12 allele at PPARG associated with short- and long-term weight loss (-0.63 and -0.93 kg/allele, P <= 0.005, respectively). Gene-treatment interactions were observed for short-term (LYPLAL1 rs2605100, P-lifestyle*SNP = 0.032; GNPDA2 rs10938397, P-lifestyle*SNP = 0.016; MTCH2 rs10838738, P-lifestyle*SNP = 0.022) and long-term (NEGR1 rs2815752, P-metformin*SNP = 0.028; FTO rs9939609, P-lifestyle*SNP = 0.044) weight loss. Three of 16 SNPs were associated with weight regain (NEGR1 rs2815752, BDNF rs6265, PPARG rs1801282), irrespective of treatment. TMEM18 rs6548238 and KTCD15 rs29941 showed treatment-specific effects (P-lifestyle*SNP < 0.05).
CONCLUSIONS-Genetic information may help identify people who require additional support to maintain reduced weight after clinical intervention.

TI Total and High-Molecular-Weight Adiponectin and Risk of Incident

AB OBJECTIVE-To delineate the associations of total adiponectin, high-molecular-weight (HMW) adiponectin, and the HMW-to-total adiponectin ratio with diabetes in older adults.
RESEARCH DESIGN AND METHODS-Total and HMW adiponectin were measured in a population-based study of older adults. The relations of total adiponectin, HMW adiponectin, and their ratio with incident diabetes (n = 309) were assessed in 3,802 individuals.
RESULTS-Total and HMW adiponectin were highly correlated (r = 0.94). Analysis using cubic splines revealed that the associations between total and HMW adiponectin and new-onset diabetes were not linear. Specifically, after adjustment for confounders, there were similar inverse relationships for total (hazard ratio per SD 0.49 [95% CI 0.39-0.63]) and HMW adiponectin (0.42 [0.32-0.56]) with diabetes up to values of 20 and 10 mg/L, respectively, above which the associations plateaued. These associations persisted after adjustment for potential mediators (blood pressure, lipids, C-reactive protein, and homeostasis model assessment of insulin resistance [HOMA-IR]). There was, however, evidence of interaction by HOMA-IR in the lower range of adiponectin, with stronger inverse associations among insulin-sensitive than insulin-resistant participants. HMW-to-total adiponectin ratio showed a linear adjusted association with outcome, but this was abolished by inclusion of mediating variables.
CONCLUSIONS-In this older cohort, increasing concentrations of total and HMW adiponectin were associated with comparably lower risks of diabetes, but these associations leveled off with further increases above concentrations of 20 and 10 mg/L, respectively. The more pronounced risk decreases at the lower range among participants without insulin resistance support a role for adiponectin that is independent of baseline hyperinsulinemia, but this will require further investigation.

AB Effector CD4+ helper T cells have historically been classified into T helper 1 (Th1) and Th2 based on the production of signature cytokines. The recently identified interleukin (IL)-17 cytokine family plays important roles in host immunity against intracellular pathogens and in chronic inflammatory conditions; data have implicated IL-17 in autoimmune and viral liver disease.
This study used three patient groups with HCV infection: acute HCV who either cleared spontaneously or became chronically infected (n = 12), endstage liver disease from whom both peripheral and intrahepatic lymphocytes were studied directly ex vivo (n = 11), and 134 patients with different stages of HCV-related fibrosis from whom serum was collected concurrently with liver biopsy. Normal healthy subjects (n = 41) served as controls.
Acute HCV was not associated with expansion of either CD4+ or CD8+ T cells producing IL-17 (Th17, Tc17) or IL-22, and frequencies did not differ in the blood of patients who cleared versus became persistently infected. The hepatic compartment of chronic HCV patients demonstrated statistically more CD4+ and CD8+ that produced IL-17, IL-22 or both as compared to peripheral blood. These T cells displayed a distinct phenotypic profile, high expression of the homing receptor CD161 and low levels of inhibitory receptors, mucin-domain-containing-molecule-3 (Tim-3) and programmed-death 1. Using a sensitive ELISA, we found no significant differences in serum levels of IL-17 according to HCV-related fibrosis.
In chronic HCV, T cells producing IL-17/IL-22 may home to the liver; however, circulating levels of IL-17 do not correlate with fibrosis.

AB A significant proportion of patients with Crohn's disease (CD) lose response to antibodies directed against tumor necrosis factor alpha (TNF). Prior TNF-antagonist failure is associated with lower rates of response to subsequent TNF-antagonist therapy. In patients failing two anti-TNF agents, a choice exists between using a third-anti-TNF therapy or natalizumab (NAT), an alpha-4 integrin inhibitor. A cost-effectiveness analysis comparing these competing strategies has not been performed.
A decision analytic model was constructed to compare the performance of certolizumab pegol (CZP) versus NAT in patients with moderate to severe CD. Previously published estimates of efficacy of third-line anti-TNF therapy and NAT were used to inform the model. Costs were expressed in 2010 US dollars. A 1-year time frame was used for the analysis.
In the base case estimate, use of NAT was only marginally more effective [0.71 vs. 0.70 quality adjusted life-years (QALYs)] than CZP but was expensive with an incremental cost-effectiveness ratio (ICER) of $381,678 per QALY gained. For CZP 2 months response rate of at least 24%, NAT had an ICER above the willingness-to-pay (WTP) threshold. The model was sensitive to the costs of both therapies; for all CZP costs below $2,300 per dose, NAT had higher ICER than the WTP threshold. Substituting adalimumab for CZP resulted in similar ICER estimates and thresholds for NAT use.
In patients with moderate to severe CD failing two TNF-antagonists, using a third TNF-antagonist therapy appears to be a cost-effective strategy without significantly compromising treatment efficacy.

AB This randomized split-mouth study was aimed at evaluating whether an orthodontic appliance per se or orthodontic tooth movement can induce detectable changes in gingival crevicular fluid (GCF) volume, and thus whether GCF volume is a predictable biomarker for tissue remodelling incident to orthodontic tooth movement. Materials and Methods: Sixteen healthy orthodontic patients (7 females and 9 males; mean age, 17.7 years; range, 13-27 years) with the need for extraction of the first upper premolars were enrolled. One randomly chosen maxillary canine was subjected to a distalizing force by a 0.017 x 0.025 inch titanium-molybdenum alloy archwire and considered as the test tooth (TT). The contralateral canine, which was not subjected to any force but was included in an orthodontic appliance, was used as a control (CT). GCF sampling was performed at both mesial and distal sites of the CTs and TTs at baseline, immediately before applying the orthodontic appliance, and after 1 hour, 24 hours, and 7, 14, and 21 days. A Periotron was used to measure the GCF volume.
A modest but significant increase in the GCF volume over time was seen in both the CTs (mesial sites) and the TTs (both mesial and distal sites) with no differences between the experimental teeth.
Subclinical tissue inflammation consequent to the placement of the orthodontic appliance might be responsible for these GCF volume changes. The GCF volume does not appear to be a reliable biomarker for tissue remodelling during orthodontic treatment.

AB This analysis was conducted to compare the effects of adjunctive ziprasidone or placebo on metabolic parameters among patients receiving maintenance treatment with lithium or valproate. We also tested whether metabolic syndrome (MetS) and other risk factors were associated with baseline characteristics and treatment response. In the stabilization phase (Phase 1), 584 bipolar I disorder (DSM-IV) patients received 2.5-4 months of open label ziprasidone (80-160 mg/d) plus lithium or valproic acid (ZIP+MS). Patients who achieved at least 8 weeks of clinical stability were subsequently randomized into Phase 2 to 6-months of double-blind treatment with ZIP+MS (n = 127) vs. placebo+MS (n=113). At baseline of Phase 1, MetS was found in 111 participants (23%). Participants with MetS (vs. non-MetS participants) were more likely to be aged 40 years or older, had significantly more severe manic symptoms, higher abdominal obesity, and higher BMI. Increase in abdominal obesity was associated with lower manic symptom improvement (p < 0.05, as assessed by MRS change score) during Phase 1, while symptom improvement differed across racial groups. In the Phase 2 double-blind phase, the ZIP+MS group had similar weight and metabolic profiles compared to the placebo+MS group across visits. These results corroborate existing findings on ziprasidone which exhibits a neutral weight and metabolic profile in the treatment of schizophrenia and bipolar patients. Our findings suggest that MetS is highly prevalent in patients with bipolar disorder, may be associated with greater manic symptom severity, and may predict treatment outcomes.

AB BACKGROUND & AIMS: The kinase Akt mediates resistance of pancreatic cancer (PaCa) cells to death and is constitutively active (phosphorylated) in cancer cells. Whereas the kinases that activate Akt are well characterized, less is known about phosphatases that dephosporylate and thereby inactivate it. We investigated regulation of Akt activity and cell death by the phosphatases PHLPP1 and PHLPP2 in PaCa cells, mouse models of PaCa, and human pancreatic ductal adenocarcinoma (PDAC). METHODS: We measured the effects of PHLPP overexpression or knockdown with small interfering RNAs on Akt activation and cell death. We examined regulation of PHLPPs by growth factors and reactive oxygen species, as well as associations between PHLPPs and tumorigenesis. RESULTS: PHLPP overexpression inactivated Akt, whereas PHLPP knockdown increased phosphorylation of Akt in PaCa cells. Levels of PHLPPs were greatly reduced in human PDAC and in mouse genetic and xenograft models of PaCa. PHLPP activities in PaCa cells were down-regulated by growth factors and Nox4 reduced nicotinamide adenine dinucleotide phosphate oxidase. PHLPP1 selectively dephosphorylated Akt2, whereas PHLPP2 selectively dephosphorylated Akt1. Akt2, but not Akt1, was up-regulated in PDAC, and Akt2 levels correlated with mortality. Consistent with these results, high levels of PHLPP1, which dephosphorylates Akt2 (but not PHLPP2, which dephosphorylates Akt1), correlated with longer survival times of patients with PDAC. In mice, xenograft tumors derived from PaCa cells that overexpress PHLPP1 (but not PHLPP2) had inactivated Akt, greater extent of apoptosis, and smaller size. CONCLUSIONS: PHLPP1 has tumor suppressive activity and might represent a therapeutic or diagnostic tool for PDAC.

TI Use of self-expandable stents in the treatment of bariatric surgery
leaks: a systematic review and meta-analysis

COMPLICATIONS; MANAGEMENT
AB Background: Bariatric surgery leaks can result in significant morbidity and mortality. Endoscopic placement of self-expandable stents (SESs) is emerging as a less-invasive alternative to surgery for the treatment of leaks.
Objective: To evaluate the success of SESs in the treatment of bariatric surgery leaks.
Design: Studies using SESs in the management of bariatric surgery leaks were selected. Success of SES treatment was defined as radiographic evidence of leak closure after stent removal. Articles were searched in MEDLINE, PubMed, Ovid, and Cochrane Register of Controlled Trials. Pooled proportions were calculated by using fixed- and random-effects models. Publication bias was calculated by using the Begg-Mazumdar and Harbord bias estimators.
Results: A total of 189 relevant articles were reviewed of which 7 studies (67 patients with leaks) met inclusion criteria. The pooled proportion of successful leak closures by using SESs was 87.77% (95% CI, 79.39%-94.19%). The pooled proportion of successful endoscopic stent removal was 91.57% (95% CI, 84.22%-96.77%). Stent migration was noted in 16.94% (95% CI, 9.32%-26.27%). Test of heterogeneity gave a P value >.10. There was no publication bias.
Limitations: Small retrospective studies, different types of stents used.
Conclusion: Endoscopic placement of SESs is a minimally invasive, safe, and effective alternative in the management of leaks after bariatric surgery. The use of SESs can minimize the need for surgical revision and improve patient outcomes. (Gastrointest.Endosc 2012;75:287-93.)

AB The tumor microenvironment of colorectal carcinoma is a complex community of genomically altered cancer cells, nonneoplastic cells, and a diverse collection of microorganisms. Each of these components may contribute to carcinogenesis; however, the role of the microbiota is the least well understood. We have characterized the composition of the microbiota in colorectal carcinoma using whole genome sequences from nine tumor/normal pairs. Fusobacterium sequences were enriched in carcinomas, confirmed by quantitative PCR and 16S rDNA sequence analysis of 95 carcinoma/normal DNA pairs, while the Bacteroidetes and Firmicutes phyla were depleted in tumors. Fusobacteria were also visualized within colorectal tumors using FISH. These findings reveal alterations in the colorectal cancer microbiota; however, the precise role of Fusobacteria in colorectal carcinoma pathogenesis requires further investigation.

AB During tumor initiation and progression, cancer cells acquire a selective advantage, allowing them to outcompete their normal counterparts. Identification of the genetic changes that underlie these tumor acquired traits can provide deeper insights into the biology of tumorigenesis. Regions of copy number alterations and germline DNA variants are some of the elements subject to selection during tumor evolution. Integrated examination of inherited variation and somatic alterations holds the potential to reveal specific nucleotide alleles that a tumor "prefers" to have amplified. Next-generation sequencing of tumor and matched normal tissues provides a high-resolution platform to identify and analyze such somatic amplicons. Within an amplicon, examination of informative (e.g., heterozygous) sites deviating from a 1:1 ratio may suggest selection of that allele. A naive approach examines the reads for each heterozygous site in isolation; however, this ignores available valuable linkage information across sites. We, therefore, present a novel hidden Markov model-based method Haplotype Amplification in Tumor Sequences (HATS) that analyzes tumor and normal sequence data, along with training data for phasing purposes, to infer amplified alleles and haplotypes in regions of copy number gain. Our method is designed to handle rare variants and biases in read data. We assess the performance of HATS using simulated amplified regions generated from varying copy number and coverage levels, followed by amplicons in real data. We demonstrate that HATS infers the amplified alleles more accurately than does the naive approach, especially at low to intermediate coverage levels and in cases (including high coverage) possessing stromal contamination or allelic bias.

AB Objective. To evaluate the utility of serum (HE4) as a marker for high risk disease in patients with endometrial cancer (EC).
Methods. Preoperative serum HE4 levels were measured from a cohort of 75 patients surgically treated for EC. Cases were compared to matched controls without a history of cancer. HE4 levels were analyzed as a function of primary tumor diameter, grade, stage and histological subtype. Wilcoxon rank-sum test, ROC curve, Spearman rank correlation coefficient and contingency tables were used for statistical analyses.
Results. Stage distribution was as follows: 49 stage I, 2 stage II, 20 stage III, 4 stage IV. Type I EC was present in 54 patients, type II in 21. Median HE4 was significantly elevated in both types land II EC compared to controls (P<0.001 and P=0.019, respectively). There was significant correlation between type I EC, median HE4, deep myometrial invasion (MI) (>50%, P<0.001) and primary tumor diameter (PTD) (>2 cm, P=0.002). Low risk patients (type I, MI <= 50% and PTD <= 2 cm) had significantly lower median HE4 compared to all other type I EC patients (P<0.01). In comparison to prior investigations, HE4 (cutoff of 8 mfi) was more sensitive than CA125 in detecting advanced stage disease.
Conclusion. Our data suggest that HE4 is elevated in a high proportion of EC patients, is correlated with PTD and MI, and is more sensitive than CA125 in EC. These observations suggest potential utility of HE4 in the preoperative prediction of high risk disease and the necessity for definitive surgical staging. (C) 2011 Elsevier Inc. All rights reserved.

AB There is a growing emphasis on the role of organizations as settings for dissemination and implementation. Only recently has the field begun to consider features of organizations that affect dissemination and implementation of evidence-based interventions. This manuscript identifies and evaluates available measures for five key organizational-level constructs: (a) leadership, (b) vision, (c) managerial relations, (d) climate, and (e) absorptive capacity. Overall the picture was the same across the five constructs-no measure was used in more than one study, many studies did not report the psychometric properties of the measures, some assessments were based on a single response per unit, and the level of the instrument and analysis did not always match. One must seriously consider the development and evaluation of a robust set of measures that will serve as the basis of building the field, allow for comparisons across organizational types and intervention topics, and allow a robust area of dissemination and implementation research to develop.

AB Aims: Endometrioid carcinoma of the endometrium (EEC) is treated with surgery and radiotherapy. Postradiation recurrences are associated with increased risk of metastases. Comparison of the expression of genes important in the development and progression of EEC, and others involved in resistance to apoptosis and hypoxia and adaptation to radiation, was performed between post-radiation vaginal recurrences (PVRs) and primary EECs. We tried to reproduce the results by exposing an EEC cell line to hypoxia and radiation.
Methods and results: Immunohistochemistry and tissue microarrays were used to compare 24 PVRs with 82 primary EECs. PVRs exhibited increased expression of p53 (P < 0.0001), cytoplasmic FLICE-inhibitory protein (FLIP) (P < 0.0001), and Ki67 (P < 0.0001), and nuclear staining for FLIP, nuclear factor kappaB (NF-kappa B) family members (p50, P < 0.0001; c-Rel, P = 0.0077; RelB, P = 0.0157), and beta-catenin (P = 0.0001). Differences regarding p50, hypoxia-inducible factor 1 alpha (HIF-1 alpha), and cytoplasmic FLIP were statistically significant when PVRs and primary EECs were matched for histological grade. Exposure of the EEC cell line to hypoxia induced nuclear expression of beta-catenin, FLIP, and HIF-1 alpha, as well as increased NF-kappa B activity. No changes in FLIP, HIF-1 alpha or NF-kappa B were seen when cells were exposed to radiation. Nuclear expression of b-catenin was seen at 3 Gy, but not at 1 Gy.
Conclusions: Genes involved in resistance to hypoxia are expressed in PVRs, and may play a role in the development of post-radiation recurrences.

AB Prominent erythroid proliferations (in which erythroid elements comprise >= 50% of total bone marrow cells) can be seen in various hematopoietic stem cell neoplasms. The myeloproliferative neoplasm polycythemia vera exhibits effective, overexuberant erythropoiesis resulting in an increased red blood cell mass; in contrast, most other diseases characterized by erythroid predominance exhibit ineffective hemopoiesis. The latter include acute erythroid leukemia (erythroid-myeloid and pure erythroid leukemia subtypes) as well as some cases of myelodysplastic syndromes, acute myeloid leukemia with myelodysplasia-related changes, and therapy-related myeloid neoplasms. Some nonneoplastic reactive conditions may also manifest a striking bone marrow erythroid predominance. In this article, we review the literature relevant to this group of diseases for a better understanding of their clinicopathologic features and surrounding controversies. We also examine the position of neoplastic erythroid proliferations in the current 2008 World Health Organization Classification of Myeloid Neoplasms and provide recommendations as to how to approach the differential diagnosis of this group of diseases.

AB SETTING : Brewelskloof Hospital, Western Cape, South Africa.
OBJECTIVES: To verify the perceived increase in rifampicin monoresistant tuberculosis (RMR-TB) in the Cape Winelands-Overberg region and to identify potential risk factors. DESIGN: A retrospective descriptive study of trends in RMR-TB over a 5-year period (2004-2008), followed by a case-control study of RMR and isoniazid (INH) monoresistant TB cases, diagnosed from April 2007 to March 2009, to assess for risk factors.
RESULTS: The total number of RMR-TB cases more than tripled, from 31 in 2004 to 98 in 2008. The calculated doubling time was 1.63 years (95%CI 1.18-2.66). For the assessment of risk factors, 95 RMR-TB cases were objectively verified on genotypic and phenotypic analysis. Of 108 specimens genotypically identified as RMR cases, 13 (12%) were misidentified multidrug-resistant TB. On multivariate analysis, previous use of antiretroviral therapy (OR 6.4, 95%CI 1.3-31.8), alcohol use (OR 4.8, 95%CI 2.0-11.3) and age >= 40 years (OR 5.8, 95%CI 2.4-13.6) were significantly associated with RMR-TB.
CONCLUSION: RMR-TB is rapidly increasing in the study setting, particularly among patients with advanced human immunodeficiency virus (HIV) disease. Routine drug susceptibility testing should be considered in all TB-HIV co-infected patients, and absence of INH resistance should be confirmed phenotypically if genotypic RMR-TB is detected.

AB The purposes of this study were to examine the cost-effectiveness of this technology and to determine improvements in patient outcome needed to make custom total knee cutting blocks cost-effective. A Markov decision model was used to evaluate the cost-effectiveness of custom cutting blocks compared with traditional instrumentation in total knee arthroplasty. The analysis demonstrates routine use of custom cutting blocks for total knee arthroplasty will not be cost-effective unless it results in a significantly reduced revision rate. The reduction necessary increases with increasing costs for the custom blocks. Further research will be necessary to determine if this can be achieved using custom cutting blocks. Patients, surgeons, payers, and institutions should consider this when determining their support of this technology in the absence of supportive data.

AB Akt and mammalian target of rapamycin (mTOR) are both activated after traumatic brain injury (TBI), however complex interplay between the two hampers deciphering their functional implications in vivo. We examined the effects of single and combination inhibitors of Akt/mTOR in a mouse controlled cortical impact (CCI) model. Following CCI, phospho-Akt-473 (p-Akt) and -S6 ribosomal protein (p-S6RP), a downstream substrate of mTOR, were increased in cortical and hippocampal brain homogenates (P<0.05 versus sham). At 24 hours, p-S6RP was detected in neurons and was robustly induced in microglia and astrocytes in injured hippocampus. In vivo activity of Akt and mTOR inhibitors administered separately was confirmed by reduced expression of p-GSK3 beta (P<0.01) or p-S6RP (P<0.05), respectively, after CCI. Importantly, administration of Akt and mTOR inhibitors together (but not of either alone) improved postinjury motor (P=0.02) and cognitive deficits (hidden platform trials, P=0.001; probe trials, P<0.05), decreased propidium iodide-positive cells in CA1 and CA3 (P<0.005), and unexpectedly increased p-GSK3 beta in hippocampus. Although the roles of Akt and mTOR in the pathogenesis of TBI remain to be fully elucidated, dual inhibition of Akt and mTOR may have therapeutic potential for TBI.

AB Cortical spreading depression (CSD) is associated with severe hypoperfusion in mice. Using minimally invasive multimodal optical imaging, we show that severe flow reductions during and after spreading depression are associated with a steep decline in cerebral metabolic rate of oxygen. Concurrent severe hemoglobin desaturation suggests that the oxygen metabolism becomes at least in part supply limited, and the decrease in cortical blood volume implicates vasoconstriction as the mechanism. In support of oxygen supply-demand mismatch, cortical nicotinamide adenine dinucleotide (NADH) fluorescence increases during spreading depression for at least 5 minutes, particularly away from parenchymal arterioles. However, modeling of tissue oxygen delivery shows that cerebral metabolic rate of oxygen drops more than predicted by a purely supply-limited model, raising the possibility of a concurrent reduction in oxygen demand during spreading depression. Importantly, a subsequent spreading depression triggered within 15 minutes evokes a monophasic flow increase superimposed on the oligemic baseline, which markedly differs from the response to the preceding spreading depression triggered in naive cortex. Altogether, these data suggest that CSD is associated with long-lasting oxygen supply-demand mismatch linked to severe vasoconstriction in mice.

AB Self-reactive natural Abs initiate injury following ischemia and reperfusion of certain tissues, but their role in ischemic stroke is unknown. We investigated neoepitope expression in the postischemic brain and the role of natural Abs in recognizing these epitopes and mediating complement-dependent injury. A novel IgM mAb recognizing a subset of phospholipids (C2) and a previously characterized anti-annexin IV mAb (B4) were used to reconstitute and characterize injury in Ab-deficient Rag1(-/-) mice after 60 min of middle cerebral artery occlusion and reperfusion. Reconstitution with C2 or B4 mAb in otherwise protected Rag1(-/-) mice restored injury to that seen in wild-type (wt) mice, as demonstrated by infarct volume, demyelination, and neurologic scoring. IgM deposition was demonstrated in both wt mice and reconstituted Rag1(-/-) mice, and IgM colocalized with the complement activation fragment C3d following B4 mAb reconstitution. Further, recombinant annexin IV significantly reduced infarct volumes in wt mice and in Rag1(-/-) mice administered normal mouse serum, demonstrating that a single Ab reactivity is sufficient to develop cerebral ischemia reperfusion injury in the context of an entire natural Ab repertoire. Finally, C2 and B4 mAbs bound to hypoxic, but not normoxic, human endothelial cells in vitro. Thus, the binding of pathogenic natural IgM to postischemic neoepitopes initiates complement-dependent injury following murine cerebral ischemia and reperfusion, and, based also on previous data investigating IgM reactivity in human serum, there appears to be a similar recognition system in both mouse and man.

AB Oncogenesis reflects an orchestrated interaction between misguided growth signals. Although much effort has been launched to pharmacologically disable activated oncogenes, one sidelined approach is the restoration of tumor suppressive signals. As TP53 is often structurally preserved, but functionally crippled, by CDKN2A/ARF loss in melanoma, rescue of p53 function represents an attractive point of vulnerability in melanoma. In this study, we showed that both p53 protein and activity levels in melanoma cells were strongly induced by nutlin-3, a canonical HDM2 antagonist. Among a test panel of 51 cell lines, there was a marked reduction in melanoma viability that was directly linked to TP53 status. Moreover, we also found that the melanoma growth suppression mediated by mitogen-activated protein kinase/extracellular signal-regulated kinase inhibition was potentiated by HDM2 antagonism. These results provide fundamental insights into the intact p53 circuitry, which can be restored through small molecule inhibitors and potentially deployed for therapeutic gain.

AB Galectin-1 (Gal-1) has been shown to play a major role in tumor immune escape by inducing apoptosis of effector leukocytes and correlating with tumor aggressiveness and disease progression. Thus, targeting the Gal-1/Gal-1 ligand axis represents a promising cancer therapeutic approach. Here, to test the Gal-1-mediated tumor immune evasion hypothesis and demonstrate the importance of Gal-1-binding N-acetyllactosamines in controlling the fate and function of antitumor immune cells, we treated melanoma-or lymphoma-bearing mice with peracetylated 4-fluoro-glucosamine (4-F-GlcNAc), a metabolic inhibitor of N-acetyllactosamine biosynthesis, and analyzed tumor growth and immune profiles. We found that 4-F-GlcNAc spared Gal-1-mediated apoptosis of T cells and natural killer (NK) cells by decreasing their expression of Gal-1-binding determinants. 4-F-GlcNAc enhanced tumor lymphocytic infiltration and promoted elevations in tumor-specific cytotoxic T cells and IFN-gamma levels, while lowering IL-10 production. Collectively, our data suggest that metabolic lowering of Gal-1-binding N-acetyllactosamines may attenuate tumor growth by boosting antitumor immune cell levels, representing a promising approach for cancer immunotherapy.

This review will summarize the pre-clinical and clinical data on the selective adenosine agonist stress agents regadenoson (Lexiscan(A (R))), binodenoson (CorVue (TM)) and apadenoson (Stedivaze (TM)) that have been studied so far with focus on regadenoson that has the most clinical data published so far. The article will review the adenosine receptor types and properties. It will also review the various attributes of the selective adenosine agonists including their pharmacology, pharmacokinetics and pharmacodynamics, their coronary vasodilatory and hemodynamic effects, their safety and side effects, their interactions with other drugs and their use with myocardial perfusion imaging. The landmark trials of the selective adenosine agonists will be reviewed as well as their use in special patient populations undergoing stress myocardial perfusion imaging.

AB Objective: This study examined associations between stimulant use and risk of cardiovascular events and symptoms in youth with attention-deficit/hyperactivity disorder and compared the risks associated with methylphenidate and amphetamines. Method: Claims were reviewed of privately insured young people 6 to 21 years old without known cardiovascular risk factors (n = 171,126). A day-level cohort analysis evaluated the risk of cardiovascular events after a diagnosis of attention-deficit/hyperactivity disorder in relation to stimulant exposures. Based on filled stimulant prescriptions, follow-up days were classified as current, past, and no stimulant use. Endpoints included an emergency department or inpatient diagnosis of angina pectoris, cardiac dysrhythmia, or transient cerebral ischemia (cardiac events) or tachycardia, palpitations, or syncope (cardiac symptoms). Results: There were 0.92 new cardiac events and 3.08 new cardiac symptoms per 1,000,000 days of current stimulant use. Compared with no stimulant use (reference group), the adjusted odds ratios of cardiac events were 0.69 (95% confidence interval 0.42-1.12) during current stimulant use and 1.18 (95% CI 0.83-1.66) during past stimulant use. The corresponding adjusted odds ratios for cardiac symptoms were 1.18 (95% CI 0.89-1.59) for current and 0.93 (95% CI 0.71-1.21) for past stimulant use. No significant differences were observed in risks of cardiovascular events (2.14, 95% CI 0.82-5.63) or symptoms (1.08, 95% CI 0.66-1.79) for current methylphenidate use compared with amphetamine use (reference group). Conclusions: Clinical diagnoses of cardiovascular events and symptoms were rare and not associated with stimulant use. The results help to allay concerns over the cardiovascular safety of stimulant treatment for attention-deficit/hyperactivity disorder in young people without known pre-existing risk factors. J. Am.

AB Objective: Recent epidemiologic studies have demonstrated that Tourette syndrome (TS) and chronic tic disorder (CT) are more common than previously recognized. However, few population-based studies have examined the prevalence of co-occurring neuropsychiatric conditions such as obsessive-compulsive disorder (OCD) and attention-deficit/hyperactivity disorder (ADHD). We evaluated the prevalence of TS, CT, and their overlap with OCD and ADHD in the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. Method: A total of 6,768 children were evaluated using longitudinal data from mother-completed questionnaires. DSM-IV-TR diagnoses of TS and CT were derived using three levels of diagnostic stringency (Narrow, Intermediate, and Broad). Validity of the case definitions was assessed by comparing gender ratios and rates of co-occurring OCD and ADHD using heterogeneity analyses. Results: Age 13 prevalence rates for TS (0.3% for Narrow; 0.7% for Intermediate) and CT (0.5% for Narrow; 1.1% for Intermediate) were consistent with rates from other population-based studies. Rates of co-occurring OCD and ADHD were higher in TS and CT Narrow and Intermediate groups compared with controls but lower than has been previously reported. Only 8.2% of TS Intermediate cases had both OCD and ADHD; 69% of TS Intermediate cases did not have either co-occurring OCD or ADHD. Conclusions: This study suggests that co-occurring OCD and ADHD is markedly lower in TS cases derived from population-based samples than has been reported in clinically ascertained TS cases. Further examination of the range of co-occurring neuropsychiatric disorders in population-based TS samples may shed new perspective on the underlying shared pathophysiology of these three neurodevelopmental conditions.

AB Objective: Little is known about the mental health care received by young people after an episode of deliberate self-harm. This study examined predictors of emergency department (ED) discharge, mental health assessments in the ED, and follow-up outpatient mental health care for Medicaid-covered youth with deliberate self-harm. Method: A retrospective longitudinal cohort analysis was conducted of national 2006 Medicaid claims data supplemented with the Area Resource File and a Substance Abuse and Mental Health Services Administration Medicaid policy survey of state policy characteristics focusing on ED treatment episodes by youth 10 to 19 years old for deliberate self-harm (n = 3,241). Rates and adjusted risk ratios (ARR) of discharge to the community, mental health assessments in the ED, and outpatient visits during the 30 days after the ED visit were assessed. Results: Most patients (72.9%) were discharged to the community. Discharge was inversely related to recent psychiatric hospitalization (ARR 0.75, 99% confidence interval [CI] 0.63-0.90). Thirty-nine percent of discharged patients received a mental health assessment in the ED and a roughly similar percentage (43.0%) received follow-up outpatient mental health care. Follow-up mental health care was directly related to recent outpatient (ARR 2.58, 99% CI 2.27-2.94) and inpatient (ARR 1.33, 99% CI 1.14-1.56) mental health care and inversely related to Hispanic ethnicity (ARR 0.78, 99% CI 0.64-0.95) and residence in a county with medium-to-high poverty rates (ARR 0.84, 99% CI 0.73 0.97). Conclusions: A substantial proportion of young Medicaid beneficiaries who present to EDs with deliberate self-harm are discharged to the community and do not receive emergency mental health assessments or follow-up outpatient mental health care.

AB Heparin-induced thrombocytopenia (HIT) is a serious, acquired, prothrombotic disorder caused by an antibody response to the heparin-platelet factor 4 complex, which can precipitate arterial as well as venous thromboembolic complications. HIT should be suspected in patients exposed to heparin who present with an unexplained thrombosis or a significant drop in platelet count, or both. Once HIT is suspected or identified, there are specific approaches to its diagnosis and management, with emphasis on removal of all heparin compounds and administration of alternative nonheparin anticoagulants. Generally, HIT is a self-limiting syndrome that resolves when the antibody titers disappear. Patients should be anticoagulated for up to 6 months, depending on the clinical scenario; however, the management of patients with remote or recent HIT requiring a vascular procedure requires special considerations.

AB Whereas most calpains are cytosolic proteases, calpain 10 is resident in mitochondria and is important in mitochondria! homeostasis. Because calpain 10 has been implicated in type 2 diabetes, we studied its possible role in diabetes-induced renal dysfunction. We treated renal proximal tubular cells with high glucose (17 mmol/l) and found decreased mitochondrial calpain 10 mRNA and protein at 96h compared with cells incubated with 0 or 5 mmol/l glucose or 17 mmol/l D-mannitol. High glucose increased mitochondrial calpain 10 substrates (NDUFB8 and ATP synthase p), decreased basal and uncoupled respiration, and initiated cell apoptosis as indicated by cleaved caspase 3 and nuclear condensation. Renal calpain 10 protein and mRNA were specifically decreased in streptozotocin-induced diabetic rats with kidney dysfunction, and in diabetic ob/ob mice. In agreement with our in vitro data, the kidneys of streptozotocin-induced diabetic rats had elevated calpain 10 substrates and cleaved caspase 3. Finally, specific siRNA-induced knockdown of calpain 10 in the proximal tubules of control rats resulted in decreased renal function as evidenced by increased serum creatinine, and increased caspase 3 cleavage compared with rats receiving scrambled siRNA. Thus, the glucose-induced loss of calpain 10 in vivo results in renal cell apoptosis and organ failure through accumulation of mitochondrial calpain 10 substrates and mitochondrial dysfunction. Whether this is a major cause of the decreased renal function in diabetic nephropathy will require further studies.

AB Family-centered care (FCC) is a partnership approach to health care decision-making between the family and health care provider. FCC is considered the standard of pediatric health care by many clinical practices, hospitals, and health care groups. Despite widespread endorsement, FCC continues to be insufficiently implemented into clinical practice. In this paper we enumerate the core principles of FCC in pediatric health care, describe recent advances applying FCC principles to clinical practice, and propose an agenda for practitioners, hospitals, and health care groups to translate FCC into improved health outcomes, health care delivery, and health care system transformation.

AB Limb salvage in fungal osteomyelitis of the post-traumatic lower extremity represents a difficult clinical problem requiring aggressive management. We report lower extremity salvage by radical bony debridement, free tissue transfer, distraction osteogenesis with bone-docking, and a novel antifungal regimen in a clinical setting of infection with Scedosporium inflatum, historically requiring amputation in 100% of cases. We treated Scedosporium inflatum osteomyelitis of the tibia and calcaneus with radical debridement of infected bone, free partial medial rectus abdominis muscle flap coverage, transport distraction osteogenesis, and combination voriconazole/terbinafine chemotherapy, a novel antifungal regimen. We achieved successful control of the infection, limb salvage, and an excellent functional outcome through aggressive debridement of infected bone and soft tissue, elimination of dead space within the bony defect, the robust perfusion provided by the free flap, the hypervascular state induced by distraction osteogenesis, and the synergism of the novel antifungal regimen.

AB A small number of rare, recurrent genomic copy number variants (CNVs) are known to substantially increase susceptibility to schizophrenia. As a consequence of the low fecundity in people with schizophrenia and other neurodevelopmental phenotypes to which these CNVs contribute, CNVs with large effects on risk are likely to be rapidly removed from the population by natural selection. Accordingly, such CNVs must frequently occur as recurrent de novo mutations. In a sample of 662 schizophrenia proband-parent trios, we found that rare de novo CNV mutations were significantly more frequent in cases (5.1% all cases, 5.5% family history negative) compared with 2.2% among 2623 controls, confirming the involvement of de novo CNVs in the pathogenesis of schizophrenia. Eight de novo CNVs occurred at four known schizophrenia loci (3q29, 15q11.2, 15q13.3 and 16p11.2). De novo CNVs of known pathogenic significance in other genomic disorders were also observed, including deletion at the TAR (thrombocytopenia absent radius) region on 1q21.1 and duplication at the WBS (Williams-Beuren syndrome) region at 7q11.23. Multiple de novos spanned genes encoding members of the DLG (discs large) family of membrane-associated guanylate kinases (MAGUKs) that are components of the postsynaptic density (PSD). Two de novos also affected EHMT1, a histone methyl transferase known to directly regulate DLG family members. Using a systems biology approach and merging novel CNV and proteomics data sets, systematic analysis of synaptic protein complexes showed that, compared with control CNVs, case de novos were significantly enriched for the PSD proteome (P=1.72 x 10(-6)). This was largely explained by enrichment for members of the N-methyl-b-aspartate receptor (NMDAR) (P=4.24 x 10(-6)) and neuronal activity-regulated cytoskeleton-associated protein (ARC) (P=3.78 x 10(-6)) postsynaptic signalling complexes. In an analysis of 18 492 subjects (7907 cases and 10 585 controls), case CNVs were enriched for members of the NMDAR complex (P=0.0015) but not ARC (P=0.14). Our data indicate that defects in NMDAR postsynaptic signalling and, possibly, ARC complexes, which are known to be important in synaptic plasticity and cognition, play a significant role in the pathogenesis of schizophrenia.

AB It is widely thought that alleles that influence susceptibility to common diseases, including schizophrenia, will frequently do so through effects on gene expression. As only a small proportion cif the genetic variance for schizophrenia has been attributed to specific loci, this remains an unproven hypothesis. The International Schizophrenia Consortium (ISC) recently reported a substantial polygenic contribution to that disorder, and that schizophrenia risk alleles are enriched among single-nucleotide polymorphisms (SNPs) selected for marginal evidence for association (P < 0.5) from genome-wide association studies (GWAS). It follows that if schizophrenia susceptibility alleles are enriched for those that affect gene expression, those marginally associated SNPs, which are also expression quantitative trait loci (eQTLs), should carry more true association signals compared with SNPs that are not marginally associated. To test this, we identified marginally associated (P < 0.5) SNPs from two of the largest available schizophrenia GWAS data sets. We assigned eQTL status to those SNPs based upon an eQTL data set derived from adult human brain. Using the polygenic score method of analysis reported by the ISC, we observed and replicated the observation that higher probability cis-eQTLs predicted schizophrenia better than those with a lower probability for being a cis-eQTL. Our data support the hypothesis that alleles conferring risk of schizophrenia are enriched among those that affect gene expression. Moreover, our data show that notwithstanding the likely developmental origin of schizophrenia, studies of adult brain tissue can, in principle, allow relevant susceptibility eQTLs to be identified.

AB Therapeutically engineered stem cells have shown promise for glioblastoma multiforme (GBM) therapy; however, key preclinical studies are urgently needed for their clinical translation. In this study, we investigated a new approach to GBM treatment using therapeutic stem cells encapsulated in biodegradable, synthetic extracellular matrix (sECM) in mouse models of human GBM resection. Using multimodal imaging, we first showed quantitative surgical debulking of human GBM tumors in mice, which resulted in increased survival. Next, sECM encapsulation of engineered stem cells increased their retention in the tumor resection cavity, permitted tumor-selective migration and release of diagnostic and therapeutic proteins in vivo. Simulating the clinical scenario of GBM treatment, the release of tumor-selective S-TRAIL (secretable tumor necrosis factor apoptosis inducing ligand) from sECM-encapsulated stem cells in the resection cavity eradicated residual tumor cells by inducing caspase-mediated apoptosis, delayed tumor regrowth and significantly increased survival of mice. This study demonstrates the efficacy of encapsulated therapeutic stem cells in mouse models of GBM resection and may have implications for developing effective therapies for GBM.

AB Percutaneous needle core biopsy is the definitive procedure by which essential diagnostic and prognostic information on acute and chronic renal allograft dysfunction is obtained. The diagnostic value of the information so obtained has endured for over three decades and has proven crucially important in shaping strategies for therapeutic intervention. This Review provides a broad outline of the utility of performing kidney graft biopsies after transplantation, highlighting the relevance of biopsy findings in the immediate and early post-transplant period (from days to weeks after implantation), the first post-transplant year, and the late period (beyond the first year). We focus on how biopsy findings change over time, and the wide variety of pathological features that characterize the major clinical diagnoses facing the clinician. This article also includes a discussion of acute cellular and humoral rejection, the toxic effects of calcineurin inhibitors, and the widely varying etiologies and characteristics of chronic lesions. Emerging technologies based on gene expression analyses and proteomics, the in situ detection of functionally relevant molecules, and new bioinformatic approaches that hold the promise of improving diagnostic precision and developing new, refined molecular pathways for therapeutic intervention are also presented.

AB The daily practice of neurointensivists focuses on the recognition of subtle changes in the neurological examination, interactions between the brain and systemic derangements, and brain physiology. Common alterations such as fever, hyperglycemia, and hypotension have different consequences in patients with brain insults compared with patients of general medical illness. Various technologies have become available or are currently being developed. The session on "research and technology" of the first neurocritical care research conference held in Houston in September of 2009 was devoted to the discussion of the current status, and the research role of state-of-the art technologies in neurocritical patients including multi-modality neuromonitoring, biomarkers, neuroimaging, and "omics" research (proteomix, genomics, and metabolomics). We have summarized the topics discussed in this session. We have provided a brief overview of the current status of these technologies, and put forward recommendations for future research applications in the field of neurocritical care.

AB Magnetic Resonance Imaging (MRI) provides various imaging modes to study the brain. We tested the benefits of a joint analysis of multimodality MRI data in combination with a large-scale analysis that involved simultaneously all image voxels using joint independent components analysis (jICA) and compared the outcome to results using conventional voxel-by-voxel unimodality tests. Specifically, we designed a jICA to decompose multimodality MRI data into independent components that explain joint variations between the image modalities as well as variations across brain regions. We tested the jICA design on structural and perfusion-weighted MRI data from 12 patients diagnosed with behavioral variant frontotemporal dementia (bvFTD) and 12 cognitively normal elderly individuals. While unimodality analyses showed widespread brain atrophy and hypoperfusion in the patients, jICA further revealed two significant joint components of variations between atrophy and hypoperfusion across brain regions. The 1st joint component revealed associated brain atrophy and hypoperfusion predominantly in the right brain hemisphere in behavioral variant frontotemporal dementia, and the 2nd joint component revealed greater atrophy relative to hypoperfusion affecting predominantly the left hemisphere in behavioral variant frontotemporal dementia. The patterns are consistent with the clinical symptoms of behavioral variant frontotemporal dementia that relate to asymmetric compromises of the left and right brain hemispheres. The joint components also revealed that that structural alterations can be associated with physiological alterations in spatially separated but potentially connected brain regions. Finally, jICA outperformed voxel-by-voxel unimodal tests significantly in terms of an effect size, separating the behavioral variant frontotemporal dementia patients from the controls. Taken together, the results demonstrate the benefit of multimodality MRI in conjunction with jICA for mapping neurodegeneration, which may lead ultimately to an improved diagnosis of behavioral variant frontotemporal dementia and other forms of neurodegenerative diseases.

AB Diffusion imaging of post-mortem brains could provide valuable data for validation of diffusion tractography of white matter pathways. Long scans (e.g., overnight) may also enable high-resolution diffusion images for visualization of fine structures. However, alterations to post-mortem tissue (T2 and diffusion coefficient) present significant challenges to diffusion imaging with conventional diffusion-weighted spin echo (DW-SE) acquisitions, particularly for imaging human brains on clinical scanners. Diffusion-weighted steady-state free precession (DW-SSFP) has been proposed as an alternative acquisition technique to ameliorate this tradeoff in large-bore clinical scanners. In this study, both DWSE and DW-SSFP are optimized for use in fixed white matter on a clinical 3-Tesla scanner. Signal calculations predict superior performance from DW-SSFP across a broad range of protocols and conditions. DW-SE and DW-SSFP data in a whole, post-mortem human brain are compared for 6- and 12-hour scan durations. Tractography is performed in major projection, commissural and association tracts (corticospinal tract, corpus callosum, superior longitudinal fasciculus and cingulum bundle). The results demonstrate superior tract-tracing from DW-SSFP data, with 6-hour DW-SSFP data performing as well as or better than 12-hour DW-SE scans. These results suggest that DW-SSFP may be a preferred method for diffusion imaging of post-mortem human brains. The ability to estimate multiple fibers in imaging voxels is also demonstrated, again with greater success in DW-SSFP data. (C) 2011 Elsevier Inc. All rights reserved.

AB Near-Infrared Spectroscopy (NIRS) allows the recovery of cortical oxy- and deoxyhemoglobin changes associated with evoked brain activity. NIRS is a back-reflection measurement making it very sensitive to the superficial layers of the head, i.e. the skin and the skull, where systemic interference occurs. As a result, the NIRS signal is strongly contaminated with systemic interference of superficial origin. A recent approach to overcome this problem has been the use of additional short source-detector separation optodes as regressors. Since these additional measurements are mainly sensitive to superficial layers in adult humans, they can be used to remove the systemic interference present in longer separation measurements, improving the recovery of the cortical hemodynamic response function (HRF). One question that remains to answer is whether or not a short separation measurement is required in close proximity to each long separation NIRS channel. Here, we show that the systemic interference occurring in the superficial layers of the human head is inhomogeneous across the surface of the scalp. As a result, the improvement obtained by using a short separation optode decreases as the relative distance between the short and the long measurement is increased. NIRS data was acquired on 6 human subjects both at rest and during a motor task consisting of finger tapping. The effect of distance between the short and the long channel was first quantified by recovering a synthetic hemodynamic response added over the resting-state data. The effect was also observed in the functional data collected during the finger tapping task. Together, these results suggest that the short separation measurement must be located as close as 1.5 cm from the standard NIRS channel in order to provide an improvement which is of practical use. In this case, the improvement in Contrast-to-Noise Ratio (CNR) compared to a standard General Linear Model (GLM) procedure without using any small separation optode reached 50% for HbO and 100% for HbR. Using small separations located farther than 2 cm away resulted in mild or negligible improvements only. (C) 2011 Elsevier Inc. All rights reserved.

AB Objective: To explain why vegetarian subjects develop morbidity and mortality from cardiovascular diseases unrelated to vitamin B status and Framingham criteria.
Methods: A study of 24 rural male subjects 18 to 30 y old and 15 urban male controls was conducted in the Sahel region of Chad. Food consumption was determined from a dietary questionnaire, and overall health status was assessed by body weight, body mass index, serum albumin, plasma transthyretin, urinary nitrogen, and creatinine. Plasma lipids, vitamins B6, BY and B12, homocysteine, and related sulfur amino acids were measured as selected cardiovascular disease risk factors.
Results: Body weight, body mass index, blood, and urinary markers of protein status were significantly lower, with an estimated 10% decrease of lean body mass in the study group compared with urban controls. Neither lipid fractions nor plasma levels of vitamins B6, B9, and B12 were significantly different between the two groups. Although the mean consumption of sulfur amino acids (10.4 mg.kg(-1).d(-1)) by rural subjects was significantly below the recommended dietary allowances (13 mg.kg(-1).d(-1)), plasma methionine values were similar in the two groups. In contrast, homocysteine concentration was significantly increased (18.6 mu mol/L, P < 0.001), and the levels of cysteine and glutathione were significantly decreased in the study group, demonstrating inhibition of the trans-sulfuration pathway. The strong negative correlation (r = -0.71) between transthyretin and homocysteine implicated lean body mass as a critical determinant of hyperhomocysteinemia.
Conclusion: The low dietary intake of protein and sulfur amino acids by a plant-eating population leads to subclinical protein malnutrition, explaining the origin of hyperhomocysteinemia and the increased vulnerability of these vegetarian subjects to cardiovascular diseases.

AB Background. Both humans and mice increase airway immunoglobulin A (IgA) after injury. This protective response is associated with TNF-alpha, IL-1 beta, and IL-6 airway increases and in mice is dependent upon these cytokines as well as enteral feeding. Parenteral nutrition (PN) with decreased enteral stimulation (DES) alters gut barrier function, decreases intestinal IgA, and decreases the principal IgA transport protein pIgR. We investigated the small intestine (SI) IgA response to injury and the role of TNT-alpha, IL-1 beta, IL-6, and PN/DES.
Methods. Expt 1: Murine kinetics of SI washing fluid (SIWF) IgA; SI, SIWF and serum TNT-alpha, IL-1 beta, and IL-6, was determined by ELISA from 0 to 8 hours after a limited surgical stress injury (laparotomy and neck incisions). Expt 2: Mice received chow or PN/DES before injury and SIWF IgA and SI pIgR levels were determined at 0 and 8 hours. Expt 3: Mice received PBS, TNT-alpha antibody, or IL-1 beta antibody 30 minutes before injury to measure effects on the SIWF IgA response. Expt 4: Mice received injury or exogenous TNF-alpha, IL-1 beta, and IL-6 to measure effects on the SIWF IgA response.
Results. Expt 1: SIWF IgA levels increased significantly by 2 hours after injury without associated increases in TNT-alpha or IL-1 beta whereas IL-6 was only increased at 1 hour after injury. Expt 2: PN/DES significantly reduced baseline SIWF IgA and SI pIgR and eliminated their increase after injury seen in Chow mice. Expt 3: TNT-alpha and IL-1 beta blockade did not affect the SIWF IgA increase after injury. Expt 4: Exogenous TNT-alpha, IL-1 beta, and IL-6 increased SIWF IgA similarly to injury.
Conclusion. The SI mucosal immune responds to injury or exogenous TNF-alpha, IL-1 beta, and IL-6 with an increase in lumen IgA, although it does not rely on local SI increases in TNT-alpha or IL-1 beta as it does in the lung. Similar to the lung, the IgA response is eliminated with.PN/DES. (Surgery 2012;151:278-86.)

AB Objectives. Auditory verbal hallucinations (AVH) are among the most common symptoms in schizophrenia. Earlier studies suggest changes in the structural connectivity of auditory areas involved in the pathophysiology of auditory hallucinations. Combining diffusion tensor imaging (DTI) and fibre tractography provides a unique opportunity to visualize and quantify entire fibre bundles. Methods. Fibre tracts connecting homotopic auditory areas via the corpus callosum were identified with DTI in ten first episode paranoid schizophrenia patients and ten healthy controls. Regions of interest were drawn manually, to guide tractography, and fractional anisotropy (FA) - a measure of fibre integrity - was calculated and averaged over the entire tract for each subject. Results. There was no difference in the FA of the interhemispheric auditory fibres between schizophrenic patients and healthy controls. However, the subgroup of patients hearing conversing voices showed increased FA relative to patients without these symptoms (P = 0.047) and trendwise increased FA relative to healthy controls (P = 0.066). In addition, a trendwise correlation between FA values and AVH symptoms (P = 0.089) was found. Conclusions. Our findings suggest that in addition to local deficits in the left auditory cortex and disturbed fronto-temporal connectivity, the interhemispheric auditory pathway might be involved in the pathogenesis of AVH.

AB Background. Bone-modifying therapy is a primary research interest in breast cancer. Several features contribute to the importance of the bone environment in the management of breast cancer. Firstly, bone metastases represent the most common site of breast cancer metastases and secondly, the emergence of cancer treatment-induced bone loss (CTIBL) among breast cancer survivors and patients is of increasing concern. Furthermore, concordant with the "seed and soil" theory, agents that alter the bone microenvironment may even prevent tumor cell seeding in bone and limit cancer growth. Material and methods. Medical databases and conference proceedings were searched to identify articles, abstracts and clinical trials that have or are investigating denosumab and bisphosphonates in cancer therapy. Our search included a predefined focus on bone-modifying therapies in early and advanced breast cancer. Results and discussion. Bisphosphonates (BPs) have an established role both in the prevention and treatment of CTIBL and have been studied in the adjuvant setting for early breast cancer (EBC). Denosumab is a monoclonal antibody directed against RANK ligand and thereby inhibits osteoclastogenesis and bone resportion. It is the newest agent approved for the treatment of postmenopausal osteoporosis and the prevention of skeletal-related events (SRE) in cancer patients with solid tumors and bone metastases. Denosumab has a favorable toxicity profile in comparison to BPs and has the potential to improve cancer outcomes. Conclusion. This review examines the existing role of denosumab in the treatment of bone complications of breast cancer and its potential role as adjuvant therapy.

TI Two-year sustained weight loss and metabolic benefits with
controlled-release phentermine/topiramate in obese and overweight adults
(SEQUEL): a randomized, placebo-controlled, phase 3 extension study

LIFE-STYLE; TOPIRAMATE; EFFICACY; SAFETY; COMBINATION; PREVENTION;
MANAGEMENT
AB Background: Obesity is a serious chronic disease. Controlled-release phentermine/topiramate (PHEN/TPM CR), as an adjunct to lifestyle modification, has previously shown significant weight loss compared with placebo in a 56-wk study in overweight and obese subjects with >= 2 weight-related comorbidities.
Objective: This study evaluated the long-term efficacy and safety of PHEN/TPM CR in overweight and obese subjects with cardiometabolic disease.
Design: This was a placebo-controlled, double-blind, 52-wk extension study; volunteers at selected sites continued with original randomly assigned treatment [placebo, 7.5 mg phentermine/46 mg controlled-release topiramate (7.5/46), or 15 mg phentermine/92 mg controlled-release topiramate (15/92)] to complete a total of 108 wk. All subjects participated in a lifestyle-modification program.
Results: Of 866 eligible subjects, 676 (78%) elected to continue in the extension. Overall, 84.0% of subjects completed the study, with similar completion rates between treatment groups. At week 108, PHEN/TPM CR was associated with significant, sustained weight loss (intent-to-treat with last observation carried forward; P < 0.0001 compared with placebo); least-squares mean percentage changes from baseline in body weight were -1.8%, -9.3%, and -10.5% for placebo, 7.5/46, and 15/92, respectively. Significantly more PHEN/TPM CR-treated subjects at each close achieved >= 5%, >= 10%, >= 15%, and >= 20% weight loss compared with placebo (P < 0.001). PHEN/TPM CR improved cardiovascular and metabolic variables and decreased rates of incident diabetes in comparison with placebo. PHEN/TPM CR was well tolerated over 108 wk, with reduced rates of adverse events occurring between weeks 56 and 108 compared with rates between weeks 0 and 56.
Conclusion: PHEN/TPM CR in conjunction with lifestyle modification may provide a well-tolerated and effective option for the sustained treatment of obesity complicated by cardiometabolic disease. This trial was registered at clinicaltrials.gov as NCT00796367. Am J Clin Nutr 2012;95:297-308.

TI Effect of titrated parenteral nutrition on body composition after
allogeneic hematopoietic stem cell transplantation in children: a
double-blind, randomized, multicenter trial

ID BONE-MARROW-TRANSPLANTATION; ACUTE LYMPHOBLASTIC-LEUKEMIA;
ENERGY-EXPENDITURE; CHILDHOOD-CANCER; ADULT SURVIVORS; SUPPORT; YOUNG;
IRRADIATION; HOMEOSTASIS; POPULATION
AB Background: Children undergoing hematopoietic stem cell transplantation (HSCT) often require parenteral nutrition (PN) to optimize caloric intake. Standard approaches to nutritional supplementation provide 130-150% of estimated energy expenditure, but resting energy expenditure (REE) may be lower than expected after HSCT. Provision of PN exceeding energy needs may lead to overfeeding and associated complications.
Objective: We conducted a blinded, randomized, controlled, multicenter trial in children undergoing HSCT to determine the effect on body composition of 2 different approaches of nutrition support: standard amounts of energy from PN (130-150% of REE) compared with PN titrated to match measured REE.
Design: Twenty-six children undergoing HSCT were randomly assigned to standard or titrated PN. Energy intake was monitored until day 30 after HSCT. Body-composition and anthropometric measures were obtained through day 100. The primary outcome variable was percentage body fat (%BF) measured by dual energy X-ray absorptiometry.
Results: The estimated change in %BF from baseline to day 30 was 1.2 +/- 0.5% in the standard group and 0.1 +/- 0.5% in the experimental group, but the overall time course of %BF did not differ significantly by treatment (P = 0.39 for time x treatment interaction). A profound loss of lean body mass (LBM) occurred in both groups during the intervention period and persisted through day 100.
Conclusions: Parenteral energy intake titrated to energy expenditure does not result in a lower accumulation of BF than does standard energy intake. Neither titrated nor standard PN regimens during HSCT preserve LBM. Alternative approaches to preserve LBM are needed. This trial is registered at clinicaltrials.gov as 00115258. Am J Clin Nutr 2012;95:342-51.

DT Article
ID LIFE-STYLE; POLYMORPHISMS; METABOLISM; FOLATE; GENES; WOMEN
AB Background: Individuals with a family history of colorectal cancer may be more susceptible to adverse effects of alcohol consumption.
Objective: We investigated whether the association between alcohol consumption and colon cancer risk differed by family history of colorectal cancer.
Design: We conducted prospective studies in women and men in the Nurses' Health Study and Health Professionals Follow-Up Study, respectively. Alcohol consumption was first assessed in 1980 in women and in 1986 in men.
Results: During a follow-up of 26 y among 87,861 women and 20 y among 47,290 men, we documented 1801 cases of colon cancer (1094 women and 707 men). Higher alcohol consumption was associated with an elevated risk of colon cancer, although the association was significant only for the highest intake category of >= 30 g/d, with no significant linear trend. The association between alcohol consumption and colon cancer risk differed by family history of colorectal cancer; in comparison with nondrinkers, the pooled multivariate RRs for alcohol consumption of >= 30 g/d were 1.23 (95% CI: 0.96, 1.57; NS) among those with no family history and 2.02 (95% CI: 1.30, 3.13) among those with a family history of colorectal cancer (P value test for difference = 0.05). In comparison with nondrinkers with no family history, the RR for colon cancer was 2.80 (95% CI: 2.00, 3.91) for individuals who consumed >= 30 g/d and who had a family history of colorectal cancer.
Conclusion: Reducing alcohol consumption may decrease the incidence of colon cancer, especially among those with a family history of colorectal cancer. Am J Clin Nutr 2012:95:413-9.

AB Molluscum contagiosum is a cutaneous poxviral infection that is rarely associated with other skin diseases, such as cutaneous neoplasms. Such associations are likely to be coincidental, except in immunocompromised patients. Kaposi sarcoma, an angioproliferative neoplasm derived from lymphatic endothelium, is mediated by human herpes virus-8 infection and occurs with increased frequency in immunocompromised individuals. We report an unusual case of molluscum contagiosum with underlying cutaneous Kaposi sarcoma diagnosed in a single skin biopsy of a human immunodeficiency virus-positive patient. Our case highlights the importance of adequate sampling to avoid missing secondary diagnoses in histopathologic sections and alerts pathologists and dermatologists to the possibility of coinfection in high-risk patients by 2 virally-mediated skin conditions.

AB Objective: We determined whether postburn hyperglycemia and insulin resistance are associated with endoplasmic reticulum (ER) stress/unfolded protein response (UPR) activation leading to impaired insulin receptor signaling.
Background: Inflammation and cellular stress, hallmarks of severely burned and critically ill patients, have been causally linked to insulin resistance in type 2 diabetes via induction of ER stress and the UPR.
Methods: Twenty severely burned pediatric patients were compared with 36 nonburned children. Clinical markers, protein, and GeneChip analysis were used to identify transcriptional changes in ER stress and UPR and insulin resistance-related signaling cascades in peripheral blood leukocytes, fat, and muscle at admission and up to 466 days postburn.
Results: Burn-induced inflammatory and stress responses are accompanied by profound insulin resistance and hyperglycemia. Genomic and protein analysis revealed that burn injury was associated with alterations in the signaling pathways that affect insulin resistance, ER/sarcoplasmic reticulum stress, inflammation, and cell growth/apoptosis up to 466 days postburn.
Conclusion: Burn-induced insulin resistance is associated with persistent ER/sarcoplasmic reticulum stress/UPR and subsequent suppressed insulin receptor signaling over a prolonged period of time. (Ann Surg 2012; 255: 370-378)

AB The major focus of this paper is to describe and evaluate current information on the role of natural killer cells (NK cells) in the pathogenesis of blistering diseases. Until now, only pemphigus vulgaris (PV) has been studied. One co-culture study demonstrated that CD4(+) T cells from the peripheral blood or perilesional skin of patients with active disease proliferate and secrete cytokines in the presence of major histocompatibility class II-expressing NK cells loaded with antigenic desmoglein self-peptides. Another study showed that NK cells can contribute to a T helper type 2-biased immune response through impaired interleukins (IL)-12 signaling and upregulation of IL, IL-10 and IL-5. Although significant data on other blistering diseases are unavailable at present, some studies implicate NK cells in disease progression. For instance, information on the role of NK cells in psoriasis and their production of tumor necrosis factor-alpha (TNF-alpha) will be provided since several TNF-alpha-inhibitors are used in its treatment. Studies on alopecia areata are also included in this paper because NK cells seem to play a key role in its pathogenesis. This review highlights the potential importance of NK cells and NKT cells as members of the large repertoire of cells and soluble mediators that play a critical role in pathogenesis of blistering diseases and other autoimmune diseases involving the skin. Therefore, the authors advocate a greater focus and interest on the study of the interaction of NK cells and the skin.

AB BACKGROUND: The benefit of adding radiation therapy after excision of ductal carcinoma in situ (DCIS) is widely debated. Randomized clinical trials are underpowered to delineate long-term outcomes after radiation. METHODS: The authors of this report constructed a Markov decision model to simulate the clinical course of DCIS in a woman aged 60 years who received treatment with either of 2 breast-conserving strategies: excision alone or excision plus radiation therapy. Sensitivity analyses were used to study the influence of risk of local recurrence, likelihood of invasive disease at recurrence, surgical choice at recurrence, and patient age at diagnosis on treatment outcomes. RESULTS: The addition of radiation therapy was associated with slight improvements in invasive disease-free and overall survival. However, radiation therapy decreased the chance of having both breasts intact over a patient's lifetime. Radiation therapy improved survival by 2.1 months for women who were diagnosed with DCIS at age 60 years but decreased the chance of having both breasts by 8.6% relative to excision alone. The differences in outcomes between the treatment strategies became smaller with increasing age at diagnosis. Sensitivity analyses revealed a greater benefit for radiation with an increased likelihood of invasive recurrence. The decrement in breast preservation with radiation therapy was mitigated by an increased likelihood of mastectomy at the time of recurrence or new breast cancer diagnosis. CONCLUSIONS: The current analysis quantified the benefits of radiation after excision of DCIS but also revealed that radiation therapy may increase the likelihood of eventual mastectomy. Therefore, the authors concluded that patient age and preferences should be considered when making the decision to add or forgo radiation for DCIS. Cancer 2012; 118: 603-11.

AB BACKGROUND: Patients with advanced soft tissue sarcomas (STS) have limited therapeutic options. Sorafenib (BAY 43-9006) is a multitargeted tyrosine kinase inhibitor of raf, vascular endothelial growth factor receptors 1 (VEGFR1) through 3, platelet-derived growth factor B, fms-like tyrosine kinase 3, and c-kit, and some of these may be relevant in STS. METHODS: The authors tested sorafenib at a dose of 400 mg twice daily in patients with advanced vascular sarcoma (VS), high-grade liposarcomas, and leiomyosarcomas who had received 0 or 1 previous regimens for advanced disease. RESULTS: Fifty-one patients were accrued to the study, and 37 were evaluable for toxicity and response. There were no unexpected side effects and no confirmed responses. The median progression-free survival was 3 months, and the median overall survival was 17 months. Six of 8 patients in the VS cohort had prolonged clinical benefit (stable disease or better), resulting in a median progression-free survival of 5 months compared with 2 to 3 months for the patients who had liposarcoma and leiomyosarcomas. CONCLUSIONS: Sorafenib at the dose and schedule studied did not result in any responses in the VS, liposarcoma, or leiomyosarcoma cohort according to Response Evaluation Criteria in Solid Tumors.

AB BACKGROUND: Statins are widely used cholesterol-lowering agents that may have potential antitumor effect. Epidemiological studies on statin use and renal cell carcinoma (RCC) risk have been inconsistent. METHODS: The authors investigated the association between statin use and RCC risk in the Nurses' Health Study and Health Professionals Follow-Up Study. In total, 80,782 women and 37,869 men were followed for 14 years and 16 years, respectively. Regular statin use was assessed at baseline and was updated biennially during follow-up. RCC diagnosis was confirmed by medical record review. RESULTS: Two hundred seventy-seven incident RCC cases (164 women and 113 men) were identified. Compared with no current use, the multivariate relative risks of current statin use were 0.68 (95% confidence interval, 0.46-1.00) in women and 1.17 (95% confidence interval, 0.75-1.82) in men. The results for ever versus never users of statins were similar. No dose-response relation with duration of statin use and RCC risk was observed. On subgroup analyses, statin use was associated with a reduced RCC risk among women who had no history of hypertension. CONCLUSIONS: The current study indicated that statin use may be associated with a lower risk of RCC in women, although these results need to be investigated further. Cancer 2012; 118: 797-803.

AB BACKGROUND: Gastroesophageal reflux disease (GERD), higher body mass index (BMI), smoking, and genetic variants in angiogenic pathway genes have been individually associated with increased risk of esophageal adenocarcinoma. However, how angiogenic gene polymorphisms and environmental factors jointly affect esophageal adenocarcinoma development remains unclear. METHODS: By using a case-only design (n = 335), the authors examined interactions between 141 functional/tagging angiogenic single nucleotide polymorphisms (SNPs) and environmental factors (GERD, BMI, smoking) in modulating esophageal adenocarcinoma risk. Gene-environment interactions were assessed by a 2-step approach. First, the authors applied random forest to screen for important SNPs that had either main or interaction effects. Second, they used case-only logistic regression to assess the effects of geneenvironment interactions on esophageal adenocarcinoma risk, adjusting for covariates and false-discovery rate. RESULTS: Random forest analyses identified 3 sets of SNPs (17 SNPs-GERD, 26 SNPs-smoking, and 34 SNPs-BMI) that had the highest importance scores. In subsequent logistic regression analyses, interactions between 2 SNPs (rs2295778 of HIF1AN, rs13337626 of TSC2) and GERD, 2 SNPs (rs2295778 of HIF1AN, rs2296188 of VEGFR1) and smoking, and 7 SNPs (rs2114039 of PDGRFA, rs2296188 of VEGFR1, rs11941492 of VEGFR1, rs17708574 of PDGFRB, rs7324547 of VEGFR1, rs17619601 of VEGFR1, and rs17625898 of VEGFR1) and BMI were significantly associated with esophageal adenocarcinoma development (all false-discovery rates <= 0.10). Moreover, these interactions tended to have SNP dose-response effects for increased esophageal adenocarcinoma risk with increasing number of combined risk genotypes. CONCLUSIONS: These findings suggest that genetic variations in angiogenic genes may modify esophageal adenocarcinoma susceptibility through interactions with environmental factors in an SNP dose-response manner.

AB The standard recommendation for treating chronic osteomyelitis is 6 weeks of parenteral antibiotic therapy. However, oral antibiotics are available that achieve adequate levels in bone, and there are now more published studies of oral than parenteral antibiotic therapy for patients with chronic osteomyelitis. Oral and parenteral therapies achieve similar cure rates; however, oral therapy avoids risks associated with intravenous catheters and is generally less expensive, making it a reasonable choice for osteomyelitis caused by susceptible organisms. Addition of adjunctive rifampin to other antibiotics may improve cure rates. The optimal duration of therapy for chronic osteomyelitis remains uncertain. There is no evidence that antibiotic therapy for >4-6 weeks improves outcomes compared with shorter regimens. In view of concerns about encouraging antibiotic resistance to unnecessarily prolonged treatment, defining the optimal route and duration of antibiotic therapy and the role of surgical debridement in treating chronic osteomyelitis are important, unmet needs.

AB Clinical decisions are ideally based on randomized trials but must often rely on observational data analyses, which are less straightforward and more influenced by methodology. The authors, from a series of expert roundtables convened by the Forum for Collaborative HIV Research on the use of observational studies to assess cardiovascular disease risk in human immunodeficiency virus infection, recommend that clinicians who review or interpret epidemiological publications consider 7 key statistical issues: (1) clear explanation of confounding and adjustment; (2) handling and impact of missing data; (3) consistency and clinical relevance of outcome measurements and covariate risk factors; (4) multivariate modeling techniques including timedependent variables; (5) how multiple testing is addressed; (6) distinction between statistical and clinical significance; and (7) need for confirmation from independent databases. Recommendations to permit better understanding of potential methodological limitations include both responsible public access to de-identified source data, where permitted, and exploration of novel statistical methods.

AB We compared the rate and extent of anidulafungins and fluconazoles activity in neutropenic and non-neutropenic mice with Candida albicans invasive candidiasis. In immunocompetent mice, anidulafungin significantly improved survival vs. controls and fluconazole, and significant reductions in (1 -> 3)-beta-D-glucan and fungal burden were observed. In neutropenic animals, the highest doses of anidulafungin (5 mg/kg) and fluconazole (10 mg/kg) also improved survival and reduced fungal burden. However, there were no differences in survival between these antifungals as anidulafungins activity was attenuated in this model. These results demonstrate that the extent of anidulafungin in vivo efficacy may be dependent on host immune status.

AB Patient comfort is not assured by common practices for terminal extubation. Treatment guidelines suggest minimizing dosage of opioids and sedatives. Multiple lines of evidence indicate that clinicians are limited in their ability to recognize distress in such patients and tend to undermedicate patients in distress. Yet suffering of any significant degree should be unacceptable. For painful procedures, such as surgery, the analogous practice of postponing anesthesia until the patient evidences discomfort would never be tolerated. Waiting for signs of suffering before initiating excellent analgesia and sedation inexorably subjects patients to distress. Therefore, when death is inevitable and imminent after extubation, suffering should be anticipated, concerns about respiratory depression dismissed, and vigorous preemptive deep sedation or anesthesia provided.

AB Type 2 diabetes (T2D) is characterized by insulin resistance and pancreatic beta-cell dysfunction, the latter possibly caused by a defect in insulin signaling in beta-cells. We hypothesized that insulin's effect to potentiate glucose-stimulated insulin secretion (GSIS) would be diminished in insulin-resistant persons. To evaluate the effect of insulin to modulate GSIS in insulin-resistant compared with insulin-sensitive subjects, 10 participants with impaired glucose tolerance (IGT), 11 with T2D, and 8 healthy control subjects were studied on two occasions. The insulin secretory response was assessed by the administration of dextrose for 80 min following a 4-h clamp with either saline infusion (sham) or an isoglycemic-hyperinsuilinemic clamp using B28-Asp-insulin (which can be distinguished immunologically from endogenous insulin) that raised insulin concentrations to high physiologic concentrations. Pre-exposure to insulin augmented GSIS in healthy persons. This effect was attenuated in insulin-resistant cohorts, both those with IGT and those with T2D. Insulin potentiates glucose-stimulated insulin secretion in insulin-resistant subjects to a lesser degree than in normal subjects. This is consistent with an effect of insulin to regulate beta-cell function in humans in vivo with therapeutic implications. Diabetes 61:301-309, 2012

AB This study investigated the mechanisms underlying tubular apoptosis in diabetes by identifying proapoptotic genes that are differentially upregulated by reactive oxygen species in renal proximal tubular cells (RFTCs) in models of diabetes. Total RNAs isolated from renal proximal tubules (RPTs) of 20-week-old heterozygous db/m+, db/db, and db/db catalase (CAT)-transgenic (Tg) mice were used for DNA chip microarray analysis. Real-time quantitative PCR assays, immunohistochemistry, and mice rendered diabetic with streptozotocin were used to validate the proapoptotic gene expression in RPTs. Cultured rat RFTCs were used to confirm the apoptotic activity and regulation of proapoptotic gene expression. Additionally, studies in kidney tissues from patients with and without diabetes were used to confirm enhanced proapoptotic gene expression in RPTs. Bcl-2-modifying factor (Bmf) was differentially upregulated (P < 0.01) in RFTs of db/db mice compared with db/m+ and dbldb CAT-Tg mice and in RPTs of streptozotocin-induced diabetic mice in which insulin reversed this finding. In vitro, Bmf cDNA overexpression in rat RPTCs coimmunoprecipated with Bcl-2, enhanced caspase-3 activity, and promoted apoptosis. High glucose (25 mmol/L) induced Bmf mRNA expression in RPTCs, whereas rotenone, catalase, diphenylene iodinium, and apocynin decreased it. Knockdown of Bmf' with small interfering RNA reduced high glucose induced apoptosis in RFTCs. More important, enhanced Bmf expression was detected in RFTs of kidneys from patients with diabetes. These data demonstrate differential upregulation of Bmf in diabetic RPTs and suggest a potential role for Bmf in regulating RPTC apoptosis and tubular atrophy in diabetes. Diabetes 61:474-484, 2012

AB The International Working Group on the Diabetic Foot expert panel on infection conducted a systematic review of the published evidence relating to treatment of foot infection in diabetes. Our search of the literature published prior to August 2010 identified 7517 articles, 29 of which fulfilled predefined criteria for detailed data extraction. Four additional eligible papers were identified from other sources. Of the total of 33 studies, 29 were randomized controlled trials, and four were cohort studies.
Among 12 studies comparing different antibiotic regimens in the management of skin and soft-tissue infection, none reported a better responsewith any particular regimen. Of seven studies that compared antibiotic regimens in patients with infection involving both soft tissue and bone, one reported a better clinical outcome in those treated with cefoxitin compared with ampicillin/ sulbactam, but the others reported no differences between treatment regimens. In two health economic analyses, there was a small saving using one regimen versus another. No published data support the superiority of any particular route of delivery of systemic antibiotics or clarify the optimal duration of antibiotic therapy in either soft-tissue infection or osteomyelitis. In one non-randomized cohort study, the outcome of treatment of osteomyelitis was better when the antibiotic choice was based on culture of bone specimens as opposed to wound swabs, but this study was not randomized, and the results may have been affected by confounding factors.
Results from two studies suggested that early surgical intervention was associated with a significant reduction in major amputation, but the methodological quality of both was low. In two studies, the use of superoxidized water was associated with a better outcome than soap or povidone iodine, but both had a high risk of bias. Studies using granulocyte-colony stimulating factor reported mixed results. There was no improvement in infection outcomes associated with hyperbaric oxygen therapy. No benefit has been reported with any other intervention, and, overall, there are currently no trial data to justify the adoption of any particular therapeutic approach in diabetic patients with infection of either soft tissue or bone of the foot.

AB This update of the International Working Group on the Diabetic Foot incorporates some information from a related review of diabetic foot osteomyelitis (DFO) and a systematic review of the management of infection of the diabetic foot. The pathophysiology of these infections is now well understood, and there is a validated system for classifying the severity of infections based on their clinical findings. Diagnosing osteomyelitis remains difficult, but several recent publications have clarified the role of clinical, laboratory and imaging tests. Magnetic resonance imaging has emerged as the most accurate means of diagnosing bone infection, but bone biopsy for culture and histopathology remains the criterion standard. Determining the organisms responsible for a diabetic foot infection via culture of appropriately collected tissue specimens enables clinicians to make optimal antibiotic choices based on culture and sensitivity results. In addition to culture-directed antibiotic therapy, most infections require some surgical intervention, ranging from minor debridement to major resection, amputation or revascularization. Clinicians must also provide proper wound care to ensure healing of the wound. Various adjunctive therapies may benefit some patients, but the data supporting them are weak. If properly treated, most diabetic foot infections can be cured. Providers practising in developing countries, and their patients, face especially challenging situations.

TI Oesophageal sensation in response to high PCO2 and acidic solutions in

AB Background Heartburn is commonly associated with the presence of acid in the oesophageal lumen. However, in patients with nonerosive reflux disease (NERD), the mechanism by which acid traverses the mucosa is not clear. We hypothesized that the luminal acid signal traverses the oesophageal epithelium in the form of the highly permeant gas CO2, which then is reconverted to H+ in the submucosa.
Materials and methods Ten patients with heartburn, normal upper endoscopy and increased oesophageal acid exposure (NERD patients) and 10 healthy subjects were enrolled. Perceptual responses to intraoesophageal acid (0.1 N HCl solution) and a high PCO2 solution were determined using a randomized cross over design. Stimulusresponse functions to perfusions were quantified by three parameters: lag time to symptom perception, intensity rating and perfusion sensitivity score.
Results In NERD patients, the difference in lag time to typical symptom perception, intensity rating and perfusion sensitivity score between high PCO2 and acid perfusions was statistically significant (P = 0.02, 0.01 and 0.02, respectively). However, the difference in the same perfusion parameters between acid and high PCO2 perfusions was nonsignificant in healthy controls. When NERD and controls were compared, the difference between the different perfusion variables was nonsignificant (adjusted to age).
Conclusions In NERD subjects, acid perfusion reliably evoked heartburn symptoms of greater intensity than in healthy controls. Nevertheless, a high PCO2 perfusion failed to produce symptoms in either group.

AB Colorectal cancer is the second leading cause of cancer death in developed countries. Genome-wide association studies (GWAS) have successfully identified novel susceptibility loci for colorectal cancer. To follow up on these findings, and try to identify novel colorectal cancer susceptibility loci, we present results for GWAS of colorectal cancer (2,906 cases, 3,416 controls) that have not previously published main associations. Specifically, we calculated odds ratios and 95% confidence intervals using log-additive models for each study. In order to improve our power to detect novel colorectal cancer susceptibility loci, we performed a meta-analysis combining the results across studies. We selected the most statistically significant single nucleotide polymorphisms (SNPs) for replication using ten independent studies (8,161 cases and 9,101 controls). We again used a meta-analysis to summarize results for the replication studies alone, and for a combined analysis of GWAS and replication studies. We measured ten SNPs previously identified in colorectal cancer susceptibility loci and found eight to be associated with colorectal cancer (p value range 0.02 to 1.8 x 10(-8)). When we excluded studies that have previously published on these SNPs, five SNPs remained significant at p < 0.05 in the combined analysis. No novel susceptibility loci were significant in the replication study after adjustment for multiple testing, and none reached genome-wide significance from a combined analysis of GWAS and replication. We observed marginally significant evidence for a second independent SNP in the BMP2 region at chromosomal location 20p12 (rs4813802; replication p value 0.03; combined p value 7.3 x 10(-5)). In a region on 5p33.15, which includes the coding regions of the TERT-CLPTM1L genes and has been identified in GWAS to be associated with susceptibility to at least seven other cancers, we observed a marginally significant association with rs2853668 (replication p value 0.03; combined p value 1.9 x 10(-4)). Our study suggests a complex nature of the contribution of common genetic variants to risk for colorectal cancer.

AB We describe a male patient (patient DGAP113) with a balanced translocation, 46,XY,t(1;3)(q31.3;q13.13), severe bilateral congenital cataracts, CNS abnormalities and mild developmental delay. Fluorescence in situ hybridization (FISH) and suppression PCR demonstrated that the chromosome 3 breakpoint lies similar to 515 kb upstream of the PVRL3 gene, while the chromosome 1 breakpoint lies similar to 50 kb upstream of the NEK7 gene. Despite the fact that NEK7 is closer to a translocation breakpoint than PVRL3, NEK7 transcript levels are unaltered in patient DGAP113 lymphoblastoid cells and Nek7-deficient mice exhibit no detectable ocular phenotype. In contrast, the expression of PVRL3, which encodes the cell adhesion protein Nectin 3, is significantly reduced in patient DGAP113 lymphoblastoid cells, likely due to a position effect caused by the chromosomal translocation. Nectin 3 is expressed in the mouse embryonic ciliary body and lens. Moreover, Pvrl3 knockout mice as well as a spontaneous mouse mutant ari (anterior retinal inversion), that maps to the Pvrl3 locus, exhibit lens and other ocular defects involving the ciliary body. Collectively, these data identify PVRL3 as a critical gene involved in a Nectin-mediated cell-cell adhesion mechanism in human ocular development.

AB Distortion-product otoacoustic emissions (DPOAEs) provide a window into real-time cochlear mechanical function. Yet, relationships between the changes in DPOAE metrics and auditory sensitivity are still poorly understood. Explicating these relationships might support the use of DPOAEs in hearing conservation programs (HCPs) for detecting early damage leading to noise-induced hearing loss (NIHL) so that mitigating steps might be taken to limit any lasting damage. This report describes the development of DPOAE-based statistical models to assess the risk of hearing loss from cisplatin treatment among cancer patients. Ototoxicity risk assessment (ORA) models were constructed using a machine learning paradigm in which partial least squares and leave-one-out cross-validation were applied, yielding optimal screening algorithms from a set of known risk factors for ototoxicity and DPOAE changes from pre-exposure baseline measures. Single DPOAE metrics alone were poorer indicators of the risk of ototoxic hearing shifts than the best performing multivariate models. This finding suggests that multivariate approaches applied to the use of DPOAEs in a HCP, will improve the ability of DPOAE measures to identify ears with noise-induced mechanical damage and/or hearing loss at each monitoring interval. This prediction must be empirically assessed in noise-exposed subjects.

AB Purpose: To report the clinical outcome and late side effect profile of proton radiotherapy in the treatment of children with parameningeal rhabdomyosarcoma (PM-RMS).
Methods and Materials: Seventeen consecutive children with PM-RMS were treated with proton radiotherapy at Massachusetts General Hospital between 1996 and 2005. We reviewed the medical records of all patients and asked referring physicians to report specific side effects of interest.
Results: Median patient age at diagnosis was 3.4 years (range, 0.4-17.6). Embryonal (n = 11), alveolar (n = 4), and undifferentiated (n = 2) histologies were represented. Ten patients (59%) had intracranial extension. Median prescribed dose was 50.4 cobalt gray equivalents (GyRBE) (range, 50.4-56.0 GyRBE) delivered in 1.8-2.0-GyRBE daily fractions. Median follow-up was 5.0 years for survivors. The 5-year failure-free survival estimate was 59% (95% confidence interval, 33-79%), and overall survival estimate was 64% (95% confidence interval, 37 82%). Among the 7 patients who failed, sites of first recurrence were local only = 2), regional only (n = 2), distant only (n = 2), and local and distant (n = 1). Late effects related to proton radiotherapy in the 10 recurrence-free patients (median follow-up, 5 years) include failure to maintain height velocity (n = 3), endocrinopathies = 2), mild facial hypoplasia (n = 7), failure of permanent tooth eruption (n = 3), dental caries (n = 5), and chronic nasal/sinus congestion (n = 2).
Conclusions: Proton radiotherapy for patients with PM-RMS yields tumor control and survival comparable to that in historical controls with similar poor prognostic factors. Furthermore, rates of late effects from proton radiotherapy compare favorably to published reports of photon-treated cohorts. (C) 2012 Elsevier Inc.

AB Spinal cord injury (SCI) results in profound bone loss due to muscle paralysis and the inability to ambulate. Sclerostin, a Wnt signaling pathway antagonist produced by osteocytes, is a potent inhibitor of bone formation. Short-term studies in rodent models have shown increased sclerostin in response to mechanical unloading that is reversed with reloading. These studies suggest that complete spinal cord injury, a condition resulting in mechanical unloading of the paralyzed lower extremities, will be associated with high sclerostin levels. We assessed the relationship between circulating sclerostin and bone density in 39 subjects with chronic SCI and 10 without SCI. We found that greater total limb bone mineral content was significantly associated with greater circulating levels of sclerostin. Sclerostin levels were reduced, not elevated, in subjects with SCI who use a wheelchair compared with those with SCI who walk regularly. Similarly, sclerostin levels were lower in subjects with SCI who use a wheelchair compared with persons without SCI who walk regularly. These findings suggest that circulating sclerostin is a biomarker of osteoporosis severity, not a mediator of ongoing bone loss, in long-term, chronic paraplegia. This is in contrast to the acute sclerostin-mediated bone loss shown in animal models of mechanical unloading in which high sclerostin levels suppress bone formation. Because these data indicate important differences in the relationship between mechanical unloading, sclerostin, and bone in chronic SCI compared with short-term rodent models, it is likely that sclerostin is not a good therapeutic target to treat chronic SCI-induced osteoporosis.

AB The selection of appropriate subjects is a critical element of successful clinical trials. Failure to properly identify, select, and retain subjects in clinical trials of antidepressant medications may affect the ability to show separation from placebo. Little is known about which type of site, academic or nonacademic, is superior in selecting and retaining appropriate subjects. In the present investigation, the authors conducted a retrospective analysis comparing the performance of academic and nonacademic sites in selecting and retaining appropriate subjects in a recently completed multi-site clinical study of aripiprazole augmentation. The authors used a set of operationalized criteria called the SAFER to identify appropriate study subjects. No significant differences were found in rates of SAFER interview passing, study completion, and clinical outcomes between academic and nonacademic sites. Our findings suggest that academic and nonacademic sites are equally effective in their ability to identify and retain appropriate study participants.

AB Timely entry into HIV care is critical for early initiation of therapy, immunologic recovery and improved survival. However, undocumented Latinos are more likely to enter HIV care late in the disease course and with concurrent AIDS. We conducted a qualitative study to examine the circumstantial, situational and social factors that uniquely affect entry and retention in care for this population. Between June and August 2006, we conducted semi-structured, in-depth, individual interviews with 22 undocumented Latino immigrants living with HIV infection. The interviews were audiotaped, transcribed and reviewed for accuracy. Data was analyzed using a grounded theory approach. Word content was coded and sorted by themes using AnSWR software. Emergent themes related to health care barriers include (1) the challenges of dealing with HIV stigma and rejection from family and community; and (2) the experienced and perceived structural barriers of accessing care as an undocumented individual. Societal intolerance of HIV and stigma-related experiences result in feelings of secrecy and shame. In addition, the undocumented state complicates the situation even further. These unique barriers include fear of deportation, work restrictions, inadequate translation services and difficulties meeting paperwork requirements. This study offers insight into the unique sociocultural and structural barriers faced by undocumented Latinos with HIV infection. Understanding and addressing these barriers will prove vital in the development and implementation of strategies to promote early entry into HIV care.

AB Chromosomal instability (CIN) has been implicated in multidrug resistance and the silencing of the ceramide transporter, CERT, promotes sensitization to diverse cytotoxics. An improved understanding of mechanisms governing multidrug sensitization might provide insight into pathways contributing to the death of CIN cancer cells. Using an integrative functional genomics approach, we find that CERT-specific multidrug sensitization is associated with enhanced autophagosomelysosome flux, resulting from the expression of LAMP2 following CERT silencing in colorectal and HER2+ breast cancer cell lines. Live cell microscopy analysis revealed that CERT depletion induces LAMP2-dependent death of polyploid cells following exit from mitosis in the presence of paclitaxel. We find that CERT is relatively over-expressed in HER2+ breast cancer and CERT protein expression acts as an independent prognostic variable and predictor of outcome in adjuvant chemotherapy-treated patients with primary breast cancer. These data suggest that the induction of LAMP2-dependent autophagic flux through CERT targeting may provide a rational approach to enhance multidrug sensitization and potentiate the death of polyploid cells following paclitaxel exposure to limit the acquisition of CIN and intra-tumour heterogeneity.

AB Premature babies are at high risk for both infantile apnoea and long-term neurobehavioural deficits. Recent studies suggest that diffuse structural changes in brain white matter are a positive predictor of poor cognitive outcomes. Since oligodendrocyte maturation, myelination, axon development, and synapse formation mainly occur in the third trimester of gestation and first postnatal year, infantile apnoea could lead to and/or exaggerate white matter impairments in preterm neonates. Therefore, we investigated oligodendroglia and axon development in a neonatal mouse model of intermittent hypoxia between postnatal days 2 and 10. During critical phases of central nervous system development, intermittent hypoxia induced hypomyelination in the corpus callosum, striatum, fornix, and cerebellum, but not in the pons or spinal cord. Intermittent hypoxia-elicited alterations in myelin-forming processes were reflected by decreased expression of myelin proteins, including MBP, PLP, MAG, and CNPase, possibly due to arrested maturation of oligodendrocytes. Ultrastructural abnormalities were apparent in the myelin sheath and axon. Immature oligodendrocytes were more vulnerable to neonatal intermittent hypoxia exposures than developing axons, suggesting that hypomyelination may contribute, at least partially, to axonal deficits. Insufficient neurofilament synthesis with anomalous components of neurofilament subunits, beta-tubulin, and MAP2 isoforms indicated immaturity of axons in intermittent hypoxia-exposed mouse brains. In addition, down-regulation of synapsin I, synaptophysin, and Gap-43 phosphorylation suggested a potential stunt in axonogenesis and synaptogenesis. The region-selective and complex impairment in brain white matter induced by intermittent hypoxia was further associated with electrophysiological changes that may underlie long-term neurobehavioural sequelae.

AB A question of great interest in current sleep research is whether and how sleep might facilitate complex cognitive skills such as decision-making. The Iowa Gambling Task (IGT) was used to investigate effects of sleep on affect-guided decision-making. After a brief standardized preview of the IGT that was insufficient to learn its underlying rule, participants underwent a 12-h delay containing either a normal nights sleep (Sleep group; N = 28) or continuous daytime wake (Wake group; N = 26). Following the delay, both groups performed the full IGT. To control for circadian effects, two additional groups performed both the preview and the full task either in the morning (N = 17) or the evening (N = 21). In the IGT, four decks of cards were presented. Draws from two advantageous decks yielded low play-money rewards, occasional low losses and, over multiple draws, a net gain. Draws from disadvantageous decks yielded high rewards, occasional high losses and, over multiple draws, a net loss. Participants were instructed to win and avoid losing as much as possible, and better performance was defined as more advantageous draws. Relative to the wake group, the sleep group showed both superior behavioral outcome (more advantageous draws) and superior rule understanding (blindly judged from statements written at task completion). Neither measure differentiated the two control groups. These results illustrate a role of sleep in optimizing decision-making, a benefit that may be brought about by changes in underlying emotional or cognitive processes.

AB Identifying predictors of subjective sleepiness and severity of sleep apnea are important yet challenging goals in sleep medicine. Classification algorithms may provide insights, especially when large data sets are available. We analyzed polysomnography and clinical features available from the Sleep Heart Health Study. The Epworth Sleepiness Scale and the apneahypopnea index were the targets of three classifiers: k-nearest neighbor, naive Bayes and support vector machine algorithms. Classification was based on up to 26 features including demographics, polysomnogram, and electrocardiogram (spectrogram). Naive Bayes was best for predicting abnormal Epworth class (010 versus 1124), although prediction was weak: polysomnogram features had 16.7% sensitivity and 88.8% specificity; spectrogram features had 5.3% sensitivity and 96.5% specificity. The support vector machine performed similarly to naive Bayes for predicting sleep apnea class (05 versus >5): 59.0% sensitivity and 74.5% specificity using clinical features and 43.4% sensitivity and 83.5% specificity using spectrographic features compared with the naive Bayes classifier, which had 57.5% sensitivity and 73.7% specificity (clinical), and 39.0% sensitivity and 82.7% specificity (spectrogram). Mutual information analysis confirmed the minimal dependency of the Epworth score on any feature, while the apneahypopnea index showed modest dependency on body mass index, arousal index, oxygenation and spectrogram features. Apnea classification was modestly accurate, using either clinical or spectrogram features, and showed lower sensitivity and higher specificity than common sleep apnea screening tools. Thus, clinical prediction of sleep apnea may be feasible with easily obtained demographic and electrocardiographic analysis, but the utility of the Epworth is questioned by its minimal relation to clinical, electrocardiographic, or polysomnographic features.

AB Objective: The study objective was to examine the utility of using proteinuria in preoperative risk stratification for acute kidney injury. Acute kidney injury is a common and important complication for patients undergoing cardiac surgery. Proteinuria, which reflects structural damage to the glomeruli or renal tubules, may aid the prediction of acute kidney injury.
Methods: The urine albumin to creatinine ratio and dipstick proteinuria concentration were prospectively measured in 1159 patients undergoing cardiac surgery. The cohort was organized into 4 clinical risk categories based on the preoperative urine albumin to creatinine ratio: 10 mg/g or less (<= 1.1 mg/mmol), 11 to 29 mg/g (1.2-3.3 mg/mmol), 30 to 299 mg/g (3.4-33.8 mg/mmol), and 300 mg/g or greater (>= 33.9 mg/mmol). The primary outcome was postoperative acute kidney injury, defined by the Acute Kidney Injury Network stage I criterion (serum creatinine increase >= 50% or >= 0.3 mg/dL; 26.5 mu mol/L).
Results: An increase in the incidence of acute kidney injury was noted across the urine albumin to creatinine ratio categories. Adding the urine albumin to creatinine ratio to the clinical model to predict acute kidney injury improved the area under the curve from 0.67 to 0.70 (P < .001), and the continuous net reclassification improvement was 29% (P < .001). The urine albumin to creatinine ratio was also independently associated with the risk of in-hospital dialysis and intensive care unit and hospital lengths of stay. Surgery status and preoperative glomerular filtration rate were effect modifiers; the association was stronger among those undergoing elective surgery and those with an estimated glomerular filtration rate of 45 mL/min/1.73 m(2) or greater.
Conclusions: Preoperative proteinuria provides graded stratification risk for acute kidney injury and is an independent predictor of other outcomes in patients undergoing cardiac surgery. (J Thorac Cardiovasc Surg 2012;143:495-502)

AB Intensive scheduling in sports requires athletes to resume physical activity shortly after injury. The purpose of this study was to investigate early isokinetic muscle strength and knee function on bone-patellar tendon-bone (BPTB) ACL reconstruction with double femoral pin fixation or interference screw technique.
A prospective study was conducted from 2008 to 2009, with 48 athletes who received femoral BPTB fixation with interference screw (n = 26) or double pin (n = 22). Clinical (IKDC objective score and hop test) and isokinetic muscle strength (peak torque (PT), PT/body weight and flexion/extension rate (F/E) in 60 and 240A degrees/s) were analyzed at 6 months of follow-up.
Analysis at baseline showed no differences between groups before surgery related to age, gender, associated injury, Tegner or Lysholm score; thus showing that groups were similar. During follow-up, however, there were significant differences between the two groups in some of the isokinetic muscle strength: PT/BW 60A degrees/s (Double Pin = 200% +/- A 13% vs. Interference Screw = 253% +/- A 16%*, *P = 0.01); F/E 60A degrees/s (Double Pin = 89% +/- A 29%* vs. Interference Screw = 74% +/- A 12%, *P = 0.04). No statistical differences between groups were observed on IKDC objective score, hop test and complications.
The significant muscle strength outcome of the interference screw group found in this study gives initial evidence that this fixation technique is useful for athletes that may need accelerated rehabilitation. Early return to sports ability signaled by isokinetic muscle strength is of clinical relevance as it is one of the main goals for athletes' rehabilitation.

AB Background: It is unknown how in-hospital cardiac arrest (IHCA) rates vary across hospitals and predictors of variability.
Objectives: Measure variability in IHCA across hospitals and determine if hospital-level factors predict differences in case-mix adjusted event rates.
Research Design: Get with the Guidelines Resuscitation (GWTG-R) (n = 433 hospitals) was used to identify IHCA events between 2003 and 2007. The American Hospital Association survey, Medicare, and US Census were used to obtain detailed information about GWTG-R hospitals.
Participants: Adult patients with IHCA.
Measures: Case-mix-adjusted predicted IHCA rates were calculated for each hospital and variability across hospitals was compared. A regression model was used to predict case-mix adjusted event rates using hospital measures of volume, nurse-to-bed ratio, percent intensive care unit beds, palliative care services, urban designation, volume of black patients, income, trauma designation, academic designation, cardiac surgery capability, and a patient risk score.
Results: We evaluated 103,117 adult IHCAs at 433 US hospitals. The case-mix adjusted IHCA event rate was highly variable across hospitals, median 1/1000 bed days (interquartile range: 0.7 to 1.3 events/1000 bed days). In a multivariable regression model, case-mix adjusted IHCA event rates were highest in urban hospitals [rate ratio (RR), 1.1; 95% confidence interval (CI), 1.0-1.3; P = 0.03] and hospitals with higher proportions of black patients (RR, 1.2; 95% CI, 1.0-1.3; P = 0.01) and lower in larger hospitals (RR, 0.54; 95% CI, 0.45-0.66; P < 0.0001).
Conclusions: Case-mix adjusted IHCA event rates varied considerably across hospitals. Several hospital factors associated with higher IHCA event rates were consistent with factors often linked with lower hospital quality of care.

AB Background: Healthcare for end-stage renal disease (ESRD) is intensive, expensive, and provided in both the public and private sector. Using a societal perspective, we examined healthcare costs and health outcomes for Department of Veterans Affairs (VA) ESRD patients comparing those who received hemodialysis care at VA versus private sector facilities.
Methods: Dialysis patients were recruited from 8 VA medical centers from 2001 through 2003 and followed for 12 months in a prospective cohort study. Patient demographics, clinical characteristics, quality of life, healthcare use, and cost data were collected. Healthcare data included utilization (VA), claims (Medicare), and patient self-report. Costs included VA calculated costs, Medicare dialysis facility reports and reimbursement rates, and patient self-report. Multivariable regression was used to compare costs between patients receiving dialysis at VA versus private sector facilities.
Results: The cohort comprised 334 patients: 170 patients in the VA dialysis group and 164 patients in the private sector group. The VA dialysis group had more comorbidities at baseline, outpatient and emergency visits, prescriptions, and longer hospital stays; they also had more conservative anemia management and lower baseline urea reduction ratio (67% vs. 72%; P < 0.001), although levels were consistent with guidelines (Kt/V >= 1.2). In adjusted analysis, the VA dialysis group had $36,431 higher costs than those in the private sector dialysis group (P < 0.001).
Conclusions: Continued research addressing costs and effectiveness of care across public and private sector settings is critical in informing health policy options for patients with complex chronic illnesses such as ESRD.

AB Background: Alcohol screening and brief interventions (BIs) are ranked the third highest US prevention priority, but effective methods of implementing BI into routine care have not been described.
Objectives: This study evaluated the prevalence of documented BI among Veterans Affairs (VA) outpatients with alcohol misuse before, during, and after implementation of a national performance measure (PM) linked to incentives and dissemination of an electronic clinical reminder (CR) for BI.
Methods: VA outpatients were included in this study if they were randomly sampled for national medical record reviews and screened positive for alcohol misuse (Alcohol Use Disorders Identification Test-Consumption score >= 5) between July 2006 and September 2008 (N = 6788). Consistent with the PM, BI was defined as documented advice to reduce or abstain from drinking plus feedback linking drinking to health. The prevalence of BI was evaluated among outpatients who screened positive for alcohol misuse during 4 successive phases of BI implementation: baseline year (n = 3504), after announcement (n = 753) and implementation (n = 697) of the PM, and after CR dissemination (n = 1834), unadjusted and adjusted for patient characteristics.
Results: Among patients with alcohol misuse, the adjusted prevalence of BI increased significantly over successive phases of BI implementation, from 5.5% (95% CI 4.1%-7.5%), 7.6% (5.6%-10.3%), 19.1% (15.4%-23.7%), to 29.0% (25.0%-33.4%) during the baseline year, after PM announcement, PM implementation, and CR dissemination, respectively (test for trend P < 0.001).
Conclusions: A national PM supported by dissemination of an electronic CR for BI was associated with meaningful increases in the prevalence of documented brief alcohol interventions.

Gender Differences in Head Impacts Sustained by Collegiate Ice Hockey Players. Med. Sci. Sports Exerc., Vol. 44, No. 2, pp. 297-304, 2012. Purpose: This study aimed to quantify the frequency, magnitude, and location of head impacts sustained by male and female collegiate ice hockey players during two seasons of play. Methods: During two seasons, 88 collegiate athletes (51 females, 37 males) on two female and male National Collegiate Athletic Association varsity ice hockey teams wore instrumented helmets. Each helmet was equipped with six single-axis accelerometers and a miniature data acquisition system to capture and record head impacts sustained during play. Data collected from the helmets were postprocessed to compute linear and rotational accelerations of the head as well as impact location. The head impact exposure data (frequency, location, and magnitude) were then compared between genders. Results: Female hockey players experienced a significantly lower (P < 0.001) number of impacts per athlete exposure than males (females = 1.7 +/- 0.7, males = 2.9 +/- 1.2). The frequency of impacts by location was the same between genders (P > 0.278) for all locations except the right side of the head, where males received fewer impacts than females (P = 0.031). Female hockey players were 1.1 times more likely than males to sustain an impact less than 50g, whereas males were 1.3 times more likely to sustain an impact greater than 100g. Similarly, males were 1.9 times more likely to sustain an impact with peak rotational acceleration greater than 5000 rad.s(-2) and 3.5 times more likely to sustain an impact greater than 10,000 rad.s(-2). Conclusions: Although the incidence of concussion has typically been higher for female hockey players than male hockey players, female players sustain fewer impacts and impacts resulting in lower head acceleration than males. Further study is required to better understand the intrinsic and extrinsic risk factors that lead to higher rates of concussion for females that have been previously reported.

AB Atherosclerotic plaque formation is fueled by the persistence of lipid-laden macrophages in the artery wall. The mechanisms by which these cells become trapped, thereby establishing chronic inflammation, remain unknown. Here we found that netrin-1, a neuroimmune guidance cue, was secreted by macrophages in human and mouse atheroma, where it inactivated the migration of macrophages toward chemokines linked to their egress from plaques. Acting via its receptor, UNC5b, netrin-1 inhibited the migration of macrophages directed by the chemokines CCL2 and CCL19, activation of the actin-remodeling GTPase Rac1 and actin polymerization. Targeted deletion of netrin-1 in macrophages resulted in much less atherosclerosis in mice deficient in the receptor for low-density lipoprotein and promoted the emigration of macrophages from plaques. Thus, netrin-1 promoted atherosclerosis by retaining macrophages in the artery wall. Our results establish a causative role for negative regulators of leukocyte migration in chronic inflammation.

AB Clinical studies indicate that phenytoin prevents acute post-traumatic seizures but not subsequent post-traumatic epilepsy. We explored this phenomenon using organotypic hippocampal slice cultures as a model of severe traumatic brain injury. Hippocampal slices were cultured for up to eight weeks, during which acute and chronic electrical recordings revealed a characteristic evolution of spontaneous epileptiform discharges, including interictal spikes, seizure activity and electrical status epilepticus. Cell death exhibited an early peak immediately following slicing, and a later secondary peak that coincided with the peak of seizure-like activity. The secondary peak in neuronal death was abolished by either blockade of glutamatergic transmission with kynurenic acid or by elimination of ictal activity and status epilepticus with phenytoin. Withdrawal of kynurenic acid or phenytoin was followed by a sharp increase in spontaneous seizure activity. Phenytoin's anticonvulsant and neuroprotective effects failed after four weeks of continuous administration. These data support the clinical findings that after brain injury, anticonvulsants prevent seizures but not epilepsy or the development of anticonvulsant resistance. We extend the clinical data by showing that secondary neuronal death is correlated with ictal but not interictal activity, and that blocking all three of these sequelae of brain injury does not prevent epileptogenesis in this in vitro model.

AB Reductions in dendritic arbor length and complexity are among the most consistently replicated changes in neuronal structure in post mortem studies of cerebral cortical samples from subjects with schizophrenia, however, the underlying molecular mechanisms have not been identified. This study is the first to identify an alteration in a regulatory protein which is known to promote both dendritic length and arborization in developing neurons, Kalirin-9. We found Kalirin-9 expression to be paradoxically increased in schizophrenia. We followed up this observation by overexpressing Kalirin-9 in mature primary neuronal cultures, causing reduced dendritic length and complexity. Kalirin-9 overexpression represents a potential mechanism for dendritic changes seen in schizophrenia. Published by Elsevier Inc.

AB This study investigated sex similarities and differences in pain-related functional connectivity in 60 healthy subjects. We used functional magnetic resonance imaging and psychophysiological interaction analysis to investigate how exposure to low vs high experimental pain modulates the functional connectivity of the periaqueductal gray (PAG). We found no sex differences in pain thresholds, and in both men and women, the PAG was more functionally connected with the somatosensory cortex, the supplemental motor area, cerebellum, and thalamus during high pain, consistent with anatomic predictions. Twenty-six men displayed a pain-induced increase in PAG functional connectivity with the amygdala caudate and putamen that was not observed in women. In an extensive literature search, we found that female animals have been largely overlooked when the connections between the PAG and the amygdala have been described, and that women are systematically understudied with regard to endogenous pain inhibition. Our results emphasize the importance of including both male and female subjects when studying basic mechanisms of pain processing, and point toward a possible sex difference in endogenous pain inhibition.

AB Hematopoietic stem cell transplantation is an effective therapy for life-threatening hematological diseases. Parents may be asked to donate hematopoietic stem cells for their child when no compatible related or unrelated donor is available. Objective: Parents donating G-CSF mobilized peripheral blood stem cells simultaneously and uniquely fulfill the dual role of donor and caregiver for their ill child. The experiences of both sibling and unrelated stem cell donors have been extensively reported but not those of parental donors. Methods: We therefore undertook a study specifically to investigate the experiences and coping strategies of parental stem cell donors. In-depth qualitative interviews were conducted with 13 parental donors, which were subsequently transcribed and subjected to thematic analysis. In addition, parental coping was assessed utilizing the Utrecht Coping List. Results: Qualitative analyses revealed four main thematic categories describing the way parental stem cell donation was experienced, namely 'Hope and Fear', 'Need for Information', 'Do Anything for your Child' and 'Transplant Outcome' In addition parents noted similar difficulties which were unrelated to their specific role as a donor, for example they felt socially isolated. Conclusions: Individual information for the parents needs to address not only the transplantation procedure but particularly those aspects related to the donation process. We feel there is a need for a protocol specifically designed to support and coach parental donors. Copyright (C) 2010 John Wiley & Sons, Ltd.

AB The benefits of an interactive online world have affected the way we purchase products and plan our vacations. It is only a matter of time before consumers start demanding health care with the same convenience that comes with booking an airline flight or managing a bank account. The health care industry itself requires periodic and mandatory data analysis for outcome analysis, clinical benchmarking, quality improvement, forming guidelines, and making decisions. The federal government and health care community have been working together to come up with more robust and cost-effective health care informatics solutions. Meaningful use (MU) intends to establish a new standard for health care informatics in the United States. The term "meaningful use implies that health care information and technology systems not just exist, but also serve as an integral,part;of physician and hospital workflow; leading to cost savings as well as improved outcomes. Under this concept, the federal government is offering maximum incentive payments of up to $44,000 per physician (including radiologists) if they can meet all the requirements as laid down in the MU measures. Unfortunately, penalties will kick in if physicians are not compliant with MU by 2015. This will be done in at least three stages, with Stage 1 already in effect (as of January 3, 2011). This will be the first in a series of articles outlining MU and What is in store for radiology. We will go in depth about who is eligible, and how the payment schedule is set up. We will break down the core and menu set measures to suggest what can be excluded by most radiologists. We will also go through some case studies and examine what lies in store for radiology.

AB The last decade has seen the evolution and ongoing refinement of a disease-oriented approach to chronic kidney disease (CKD). Disease-oriented models of care assume a direct causal association between observed signs and symptoms and underlying disease pathophysiologic processes. Treatment plans target underlying disease mechanisms with the goal of improving disease-related outcomes. Because average glomerular filtrate rates tend to decrease with age, CKD becomes increasingly prevalent with advancing age and those who meet criteria for CKD are disproportionately elderly. However, several features of geriatric populations may limit the utility of disease-oriented models of care. In older adults, complex comorbid conditions and geriatric syndromes are common; signs and symptoms often do not reflect a single underlying pathophysiologic process; there can be substantial heterogeneity in life expectancy, functional status, and health priorities; and information about the safety and efficacy of recommended interventions often is lacking. For all these reasons, geriatricians have tended to favor an individualized patient-centered model of care over more traditional disease-based approaches. An individualized approach prioritizes patient preferences and embraces the notion that observed signs and symptoms often do not reflect a single unifying disease process and instead reflect the complex interplay between many different factors. This approach emphasizes modifiable outcomes that matter to the patient. Prognostic information related to these and other outcomes generally is used to shape rather than dictate treatment decisions. We argue that an individualized patient-centered approach to care may have more to offer than a traditional disease-based approach to CKD in many older adults. Am J Kidney Dis. 59(2):293-302.

AB Stineman MG, Henry-Sanchez JT, Kurichi JE, Pan Q, Xie D, Saliba D, Zhang Z, Streim JE: Staging activity limitation and participation restriction in elderly community-dwelling persons according to difficulties in self-care and domestic life functioning. Am J Phys Med Rehabil 2012; 91: 126-140.
Objective: This study aimed to describe the conceptual foundation and development of an activity limitation and participation restriction staging system for community-dwelling people 70 yrs or older according to the severity and types of self-care (activities of daily living [ADLs]) and domestic life (instrumental ADLs (IADLs)) limitations experienced.
Design: Data from the second Longitudinal Study of Aging (N = 9447) were used to develop IADL stages through the analyses of self- and proxy-reported difficulties in performing IADLs. An analysis of activity limitation profiles identified hierarchical thresholds of difficulty that defined each stage. IADL stages are combined with ADL stages to profile status for independent living.
Results: IADL stages define five ordered thresholds of increasing activity limitations and a "not relevant'' stage for those who normally have someone else do those activities. Approximately 42% of the population experience IADL limitations. To achieve a stage, a person must meet or exceed stage-specific thresholds of retained functioning defined for each activity. Combined ADL and IADL stages define 29 patterns of activity limitations expressing the individual's potential for participating in life situations pertinent to self- care and independent community life.
Conclusions: ADL and IADL stages can serve to distinguish between groups of people according to both severity and the types of limitations experienced during home or outpatient assessments, in population surveillance, and in research.

AB Objective: The liver is the key organ involved in systemic inflammation, but the relation between hepatic inflammation and atherogenesis is poorly understood. Since nuclear factor-kappa B (NF-kappa B) is a central regulator of inflammatory processes, we hypothesized that chronically enhanced hepatic NF-kappa B activation, through hepatocyte-specific expression of I kappa B kinase-beta (IKK beta) (LIKK), will aggravate atherosclerosis development in APOE*3-Leiden (E3L) mice.
Methods and results: E3L. LIKK and E3L control littermates were fed a Western-type diet for 24 weeks. E3L. LIKK mice showed a 2.3-fold increased atherosclerotic lesion area and more advanced atherosclerosis in the aortic root with less segments without atherosclerotic lesions (11% vs. 42%), and more segments with mild (63% vs. 44%) and severe (26% vs. 14%) lesions. Expression of LIKK did not affect basal levels of inflammatory parameters, but plasma cytokine levels tended to be higher in E3L. LIKK mice after lipopolysaccharide (LPS) administration. E3L.LIKK mice showed transiently increased plasma cholesterol levels, confined to (V) LDL. This transient character resulted in a mild (+17%) increased cumulative plasma cholesterol exposure.
Conclusion: We conclude that selective activation of NF-kappa B in hepatocytes considerably promotes atherosclerosis development which is (at least partly) explained by an increased sensitivity to proinflammatory triggers and transiently increased plasma cholesterol levels.

AB Objective: Serum adiponectin protects against incident ischemic heart disease (IHD). However, in patients with existing IHD, higher adiponectin levels are paradoxically associated with worse outcomes. We investigated this paradox by evaluating the relationship between adiponectin and cardiovascular events in patients with existing IHD.
Methods: We measured total serum adiponectin and cardiac disease severity by stress echocardiography in 981 outpatients with stable IHD who were recruited for the Heart and Soul Study between September 2000 and December 2002. Subsequent heart failure hospitalizations, myocardial infarction, and death were recorded.
Results: During an average of 7.1 years of follow-up, patients with adiponectin levels in the highest quartile were more likely than those in the lowest quartile to be hospitalized for heart failure (23% vs. 13%; demographics-adjusted hazard ratio (HR) 1.63, 95% confidence interval (CI) 1.04-2.56, p = 0.03) or die (49% vs. 31%; HR 1.67, 95% CI 1.24-2.26, p < 0.008), but not more likely to have a myocardial infarction (12% vs. 17%; HR 0.64, 95% CI 0.38-1.06, p = 0.08). The combined outcome of myocardial infarction, heart failure, or death occurred in 56% (136/245) of participants in the highest quartile of adiponectin vs. 38% (94/246) of participants in the lowest quartile (HR 1.54, 95% CI 1.31-2.21, p < 0.002). Adjustment for left ventricular ejection fraction, diastolic dysfunction, inducible ischemia, C-reactive protein, and NT-proBNP attenuated the association between higher adiponectin and increased risk of subsequent events (HR 1.43, 95% CI 0.98-2.09, p = 0.06).
Conclusions: Higher concentrations of adiponectin were associated with heart failure and mortality among patients with existing IHD. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB Hematopoietic cell transplantation (HCT) is the only known curative therapy for many patients with life-threatening hematologic and oncologic diseases. It is estimated that the National Marrow Donor Program (NMDP) will facilitate 10,000 transplants by 2015, double the current number. To better understand the existing personnel and center infrastructure for HCT in the country and to address system capacity challenges to the future growth of HCT, the NMDP convened a diverse group of stakeholders and thought leaders representing HCT physicians, physician assistants, nurse practitioners, nurses, pharmacists, other healthcare providers, HCT program directors, hospital administrators, payors, and professional organizations. Working groups were formed to identify: capacity issues because of shortages in human resources, structural constraints, and patient access barriers including diversity and healthcare disparity challenges; recommendations to address challenges; and stakeholders to engage. This report details the deliberations and recommendations of a national symposium, "Hematopoietic Cell Transplantation in 2020: A Health Care Resource and Infrastructure Assessment," held in September 2010.

AB Cytogenetics play a major role in determining the prognosis of patients with acute myelogenous leukemia (AML). However, existing cytogenetics classifications were developed in chemotherapy-treated patients and might not be optimal for patients undergoing allogeneic hematopoietic cell transplantation (HCT). We studied 821 adult patients reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) who underwent HCT for AML in first or second complete remission between 1999 and 2004. We compared the ability of the 6 existing classifications to stratify patients by overall survival. We then defined a new scheme specifically applicable to patients undergoing HCT using this patient cohort. Under this scheme, inv(16) is favorable, a complex karyotype (4 or more abnormalities) is adverse, and all other classified abnormalities are intermediate in predicting survival after HCT (5-year overall survival, 64%, 18%, and 50%, respectively; P = .0001). This scheme stratifies patients into 3 groups with similar non-relapse mortality, but significantly different incidences of relapse, overall and leukemia-free survival. It applies to patients regardless of disease status (first or second complete remission), donor type (matched related or unrelated), or conditioning intensity (myeloablative or reduced intensity). This transplantation-specific classification could be adopted for prognostication purposes and to stratify patients with AML and karyotypic abnormalities entering HCT clinical trials.

AB Hepatic glucose metabolism is a key player in diseases such as obesity and diabetes as well as in antihyperglycemic drugs screening. Hepatocytes culture in two-dimensional configurations is limited in vitro model for hepatocytes to function properly, while truly practical platforms to perform three-dimensional (3D) culture are unavailable. In this work, we present a practical organoid culture method of hepatocytes for elucidation of glucose metabolism under nominal and stress conditions. Employing this new method of culturing cells within a hollow fiber reactor, hepatocytes were observed to self-assemble into 3D spherical organoids with preservation of tight junctions and display increased liver-specific functions. Compared to both monolayer culture and sandwich culture, the hepatocyte organoids displayed higher intracellular glycogen content, glucose consumption, and gluconeogenesis and approached the in vivo values, as also confirmed by gene expression of key enzymes. Moreover, hepatocyte organoids demonstrated more realistic sensitivity to hormonal challenges with insulin, glucagon, and dexamethasone. Finally, the exposure to high glucose demonstrated toxicities including alteration of mitochondrial membrane potential, lipid accumulation, and reactive oxygen species formation, similar to the in vivo responses, which was not captured by monolayer cultures. Collectively, hepatocyte organoids mimicked the in vivo functions better than hepatocyte monolayer and sandwich cultures, suggesting suitability for applications such as antihyperglycemic drugs screening.

AB Background: Diagnostic errors in primary care are harmful but difficult to detect. The authors tested an electronic health record (EHR)-based method to detect diagnostic errors in routine primary care practice.
Methods: The authors conducted a retrospective study of primary care visit records 'triggered' through electronic queries for possible evidence of diagnostic errors: Trigger 1: A primary care index visit followed by unplanned hospitalisation within 14 days and Trigger 2: A primary care index visit followed by >= 1 unscheduled visit(s) within 14 days. Control visits met neither criterion. Electronic trigger queries were applied to EHR repositories at two large healthcare systems between 1 October 2006 and 30 September 2007. Blinded physician-reviewers independently determined presence or absence of diagnostic errors in selected triggered and control visits. An error was defined as a missed opportunity to make or pursue the correct diagnosis when adequate data were available at the index visit. Disagreements were resolved by an independent third reviewer.
Results: Queries were applied to 212 165 visits. On record review, the authors found diagnostic errors in 141 of 674 Trigger 1-positive records (positive predictive value (PPV)=20.9%, 95% CI 17.9% to 24.0%) and 36 of 669 Trigger 2-positive records (PPV=5.4%, 95% CI 3.7% to 7.1%). The control PPV of 2.1% (95% CI 0.1% to 3.3%) was significantly lower than that of both triggers (p <= 0.002). Inter-reviewer reliability was modest, though higher than in comparable previous studies (K=0.37 (95% CI 0.31 to 0.44)).
Conclusions: While physician agreement on diagnostic error remains low, an EHR-facilitated surveillance methodology could be useful for gaining insight into the origin of these errors.

AB Observational studies have demonstrated a decreased incidence of cancers among users of HMG CoA reductase inhibitors (statins) and a reduced risk of recurrence among statin users diagnosed with early stage breast cancer. We initiated a prospective study to identify potential biomarkers of simvastatin chemopreventive activity that can be validated in future trials. The contralateral breast of women with a previous history of breast cancer was used as a high-risk model. Eligible women who had completed all planned treatment of a prior stage 0-III breast cancer received simvastatin 40 mg orally daily for 24-28 weeks. At baseline and end-of-study, we measured circulating concentrations of high-sensitivity C-reactive protein (hsCRP), estrogens, and fasting lipids; breast density on contralateral breast mammogram; and quality of life by Rand Short Form 36-Item health survey. Fifty women were enrolled with a median age of 53 years. Total cholesterol, LDL cholesterol, triglyceride, and hsCRP fell significantly during the study (P values < 0.001, < 0.001, 0.003, and 0.05, respectively). Estrone sulfate concentrations decreased with simvastatin treatment (P = 0.01 overall), particularly among post-menopausal participants (P = 0.006). We did not observe a significant change in circulating estradiol or estrone concentrations, contralateral mammographic breast density, or reported physical functioning or pain scores. This study demonstrates the feasibility of short-term biomarker modulation studies using the contralateral breast of high-risk women. Simvastatin appears to modulate estrone sulfate concentrations and its potential chemopreventive activity in breast cancer warrants further investigation.

AB Prior studies have suggested a higher prevalence of high grade, ER-negative, HER2-positive, and basal-like carcinomas in young women with breast cancer. However, the precise distribution of poor prognostic features in this population remains unclear. We examined the pathologic features and distribution of molecular phenotype in relation to patient age in a large group of young women (a parts per thousand currency sign40 years) with invasive breast cancer. Medical records were reviewed for clinical characteristics, tumor stage, and receptor status. Pathologic features, including those features associated with basal-like carcinomas, were examined by central review. Using tumor grade and biomarker expression, cancers were categorized as luminal A (ER+ and/or PR+ and HER2-, histologic grade 1 or 2); luminal B (ER+ and/or PR+ and HER2+, or ER and/or PR+, HER2- and grade 3); HER2 (ER and PR- and HER2+); and triple negative (ER-, PR-, and HER2-). Among 399 women of a parts per thousand currency sign40 years, 33% had luminal A tumors, 35% luminal B, 11% HER2 (ER-negative), and 21% triple negative. Compared to published results for all breast cancers, a greater proportion of young women had luminal B tumors, and a lesser proportion had luminal A. There were no significant differences in molecular phenotype, tumor stage or grade among the different age groups of young women. However, this population of young women presented with a different distribution of molecular phenotypes compared to the general population of women with breast cancer. These findings may have implications with regard to the etiology and prognosis of breast cancer in young women.

AB Negative emotional signals are known to influence task performance, but so far, investigations have focused on how emotion interacts with perceptual processes by mobilizing attentional resources. The attention-independent effects of negative emotional signals are less well understood. Here, we show that threat signals trigger defensive responses independently of what observers pay attention to. Participants were scanned using functional magnetic resonance imaging while watching short video clips of threatening actions and performed either color or emotion judgments. Seeing threatening actions interfered with performance in both tasks. Amygdala activation reflected both stimulus and task conditions. In contrast, threat stimuli prompted a constant activity in a network underlying reflexive defensive behavior (periaqueductal gray, hypothalamus, and premotor cortex). Threat stimuli also disrupted ongoing behavior and provoked motor conflict in prefrontal regions during both tasks. The present results are consistent with the view that emotions trigger adaptive action tendencies independently of task settings.

AB Cerebral axonal connections begin to develop before birth during radial migration in each brain area. A number of theories are still actively debated regarding the link between neuronal migration, developing connectivity, and gyrification. Here, we used high angular resolution diffusion tractography on postmortem fetal human brains (postconception week (W) 17-40) to document the regression of radial and tangential organization likely to represent migration pathways and the emergence of corticocortical organization and gyrification. The dominant radial organization at W17 gradually diminished first in dorsal parieto-occipital and later in ventral frontotemporal regions with regional variation: radial organization persisted longer in the crests of gyri than at the depths of sulci. The dominant tangential organization of the ganglionic eminence at W17 also gradually disappeared by term, together with the disappearance of the ganglionic eminence. A few immature long-range association pathways were visible at W17, gradually became evident by term. Short-range corticocortical tracts emerged prior to gyrification in regions where sulci later developed. Our results suggest that the regional regression of radial organization and regional emergence of fetal brain connectivity proceeds in general from posterodorsal to anteroventral with local variations.

AB Defining the epidemiology of adverse events after THA will aid in the development of strategies to enhance perioperative care.
We identified (1) risk factors for adverse events in Medicare beneficiaries while hospitalized after THA and (2) trends in the rates of adverse events.
Data were abstracted from medical records of 1809 Medicare beneficiaries who underwent THA from 2002 to 2007. We used the hierarchical generalized linear modeling approach to assess the odds of change in adverse events over time, the association of adverse events with outcomes, and the relationship of adverse events with patient characteristics by modeling the log-odds of adverse events as a function of demographic and clinical variables adjusted for year variable.
The overall rate of adverse events was 5.8%; the 30-day mortality rate was 1.00%. Increased age, obesity, and year of procedure were risk factors for experiencing any adverse event. Annual rates of adverse events from 2002 to 2007 were 9.1%, 8.2%, 4.9%, 4.1%, 3.5%, and 3.0%, respectively. Experiencing any adverse event was associated with an increased length of stay and an increased chance of readmission but not with an increased chance of mortality. The annual rate of all adverse events decreased from 2002-2004 to 2005-2007 (odds ratio = 0.83; 95% confidence interval, 0.74-0.92).
Older and obese patients should be counseled regarding their increased risk for the development of adverse events after THA. The cause of the decline in the rate of adverse events between two time periods is unclear and warrants further investigation to confirm and identify the cause.

AB Stroke is the fourth leading killer in the United States and a leading cause of adult long-term disability. The American Heart Association estimates that only 3% to 5% of patients with acute ischemic stroke are treated with intravenous thrombolysis. A way to improve the rates of treatment with thrombolysis in patients with acute ischemic stroke is the creation of telemedicine stroke networks. Data from many studies support the safety of expanding intravenous tissue plasminogen activator use with the help of telemedicine. In this article we discuss the current evidence for the use of telemedicine within stroke systems of care, the importance of coordinating care within the transferring facilities in the telestroke networks, telestroke economics and applicability, and how to potentially use the telestroke systems to increase recruitment of patients into acute stroke thrombolysis trials.

AB Purpose of review
For women aged 40-49 years, to describe the benefits and harms of performing screening mammography, accuracy of digital mammography, and new evidence on the effectiveness of risk-based screening.
Recent findings
New data support a 15% reduction in breast cancer mortality for women aged 40-49 years after 10 years of screening; however, the absolute benefit is small and not outweighed by important harms. Digital mammography is more sensitive, but less specific than film mammography in women aged 40-49 years. Risk-based screening that identifies and screens women aged 40-49 years with breast cancer risk similar to an average-risk woman aged 50-59 years results in similar benefits and harms of screening these high-risk women as screening average-risk 50-year-old women.
Summary
Practitioners should discuss with women aged 40-49 years the benefits and harms of undergoing screening mammography before offering them screening. If women elect to undergo screening mammography, they should undergo biennial screening with digital mammography. Targeting screening for those women aged 40-49 years with risk factors that substantially increase the risk of breast cancer, such as high breast density, family history of breast cancer, and history of benign breast biopsy, could maximize the benefits and minimizes the harms of screening this age group.

AB With the development of a measure of serious psychological distress (SPD) in 2002, more attention is being paid to the association of SPD with diabetes outcomes and processes of care. We review the literature on the relationship between SPD and diabetes processes of care and outcomes, as well as the literature on the relationship between specific mental health diagnoses and diabetes processes of care and outcomes during the 2010 to 2011 period. There is an extensive literature on the association of mental health diagnoses with diabetes outcomes, especially for depression. Because the Kessler scale measures a much broader range of mental health issues than any specific DSM-IV/Structured Clinical Interview for DSM Disorders diagnosis and is designed to assess SPD at the population level, additional research needs to be conducted both in clinical settings and using large administrative datasets to examine the association between SPD and diabetes outcomes and processes of care.

AB Individuals with schizotypal personality disorder (SPD) share genetic, phenomenologic, and cognitive abnormalities with people diagnosed with schizophrenia. To date, 15 structural MRI studies of the brain have examined size, and 3 diffusion tensor imaging studies have examined white matter connectivity in SPD. Overall, both types of structural neuroimaging modalities have shown temporal lobe abnormalities similar to those observed in schizophrenia, while frontal lobe regions appear to show more sparing. This intriguing pattern suggests that frontal lobe sparing may suppress psychosis, which is consistent with the idea of a possible neuroprotective factor. In this paper, we review these 18 studies and discuss whether individuals with SPD who both resemble and differ from schizophrenia patients in their phenomenology, share some or all of the structural brain imaging characteristics of schizophrenia. We attempt to group the MRI abnormalities in SPD into three patterns: 1) a spectrum of severity-abnormalities are similar to those observed in schizophrenia but not so severe; 2) a spectrum of region-abnormalities affecting some, but not all, brain regions affected in schizophrenia; and 3) a spectrum of compensation-abnormalities reflecting greater-than-normal white matter volume, possibly serving as a buffer or compensatory mechanism protecting the individual with SPD from the frank psychosis observed in schizophrenia.

AB Background: Quantitative MRA (qMRA) is a relatively new technique that uses traditional time-of-flight and phase-contrast MRI to visualize extracranial and intracranial vascular anatomy and measure volumetric blood flow. We aimed to assess the clinical utility of qMRA in assessing the hypothesized pathophysiology (HP) in a range of cerebrovascular diseases. Moreover, we postulated that evaluation of the arterial waveforms, can improve the evaluation of the hypothesized pathophysiology by qMRA.
Methods: We reviewed studies from 10 patients who underwent qMRA examinations before and after their treatments. Two reviewers assessed the anatomy, volumetric flow rates and arterial waveforms for each vessel sampled and reached a consensus as to whether the above parameters supported the clinical diagnosis/hypothesized pathophysiology and the subsequent management.
Findings: All 20 qMRA studies were technically adequate. qMRA supported the HP in all 10 patients as determined by abnormal volumetric flow values in the affected vessels before treatment and by the correction of these abnormal values in the patients whose treatment was successful. Each of our five patients with occlusive disease/vasoconstriction demonstrated evidence of dampening of the arterial waveforms distally to the narrowed artery (parvus-tardus phenomenon). The parvus-tardus effect disappeared after treatment.
Conclusion: qMRA is unique in combining time-of-flight MRA in a complementary manner with phase-contrast MRA to obtain volumetric flow values and potentially important physiologic information from arterial waveform analysis in patients with a range of cerebrovascular diseases during the course of a single MR examination.

AB Objective. To translate a set of evidence-based clinical standards designed to allow paramedics to forgo unnecessary and potentially harmful resuscitation attempts into a feasible new policy.
Data Sources/Setting. Policy documents, meeting minutes, and personal communications between a large urban Emergency Medical Services (EMS) agency serving all of Los Angeles County (LAC) and a research group were reviewed over 12 months.
Study Design. LAC EMS and University of California, Los Angeles (UCLA) formed a partnership (the EMS-UCLA Collaborative) to develop and translate the standards into new EMS protocols. Clinical indicators considered appropriate and feasible by an expert panel were submitted to the agency for inclusion in the new policy.
Findings. The Collaborative submitted the results to the LAC EMS Commission and a physician advisory group for review. Of the 41 indicators approved by the expert panel, 22 would have resulted in changes to the current policy. All six involved asking family members about or honoring written and verbal Do Not Attempt Resuscitate requests, but only 4 of the 16 indicators based on clinical characteristics were included in the new policy. Ultimately, 10 of the 22 indicators that would have changed policy were approved and implemented.
Conclusions. By collaboration, a large EMS agency and a research team were able to develop and implement a revised resuscitation policy within 1 year.

AB Objective. To identify prevalences and predictors of nonfinancial barriers that lead to unmet need or delayed care among U.S. adults.
Data Source. 2007 Health Tracking Household Survey.
Study Design. Reasons for unmet need or delayed care in the previous 12 months were assigned to one of five dimensions in the Penchansky and Thomas model of access to care. Prevalences of barriers in each nonfinancial dimension were estimated for all adults and for adults with affordability barriers. Multivariable logistic regression models were used to estimate associations between individual, household, and insurance characteristics and barriers in each access dimension.
Principal Findings. Eighteen percent of U.S. adults experienced affordability barriers and 21 percent experienced nonfinancial barriers that led to unmet need or delayed care. Two-thirds of adults with affordability barriers also reported nonfinancial barriers. Young adults, women, individuals with lower incomes, parents, and persons with at least one chronic illness had higher adjusted prevalences of nonfinancial barriers.
Conclusions. Nonfinancial barriers are common reasons for unmet need or delayed care among U.S. adults and frequently coincide with affordability barriers. Failure to address nonfinancial barriers may limit the impact of policies that seek to expand access by improving the affordability of health care.

AB Background: Growth failure remains a common complication of pediatric Crohn's disease (CD) and has been associated with small bowel involvement and need for surgery. We have reported that patients with elevated (=1.6 mu g/mL) granulocyte macrophage colony stimulating factor autoantibodies (GM-CSF Ab) are more likely to experience complicated ileal disease requiring surgery. We hypothesized that concurrent GM-CSF Ab and CARD15 risk allele carriage (C15(+)GMAb(+)) would be associated with growth failure in CD and growth hormone (GH) resistance in murine ileitis.
Methods: We enrolled 229 pediatric CD patients at two sites and determined CARD15 genotype, serum GM-CSF Ab, and GH binding protein (GHBP), and height (HTz) and weight (WTz) z-scores at diagnosis. Ileitis was induced in card15-deficient mice by GM-CSF neutralization and nonsteroidal antiinflammatory drug (NSAID) exposure. Hepatic GH receptor (GHR) abundance and GH-dependent Stat5 activation were determined by western blot and Igf-I mRNA expression by real-time polymerase chain reaction (PCR).
Results: Mean (95% confidence interval [CI]) HTz at diagnosis was reduced to -0.48 (-4.2, 2.3) in C15(+)GMAb(+) patients, compared to -0.07 (-4.9, 3.4) in disease controls (P <= 0.05). Circulating GHBP, as a marker for tissue GHR abundance, was reduced in C15(+)GMAb(+) patients. Hepatic GHR abundance, GH induction of Stat5 tyrosine phosphorylation, and Igf-I mRNA expression were reduced in male card15-deficient mice with ileitis due to GM-CSF neutralization and NSAID exposure.
Conclusions: Innate dysfunction due to concurrent genetic variation in CARD15 and neutralizing GM-CSF Ab is associated with linear growth failure in pediatric CD, and hepatic GH resistance in murine ileitis.

AB Background: The immediate early response gene X-1 (IEX-1) is a stress-inducible gene involved in the regulation of cell growth, apoptosis and inflammation.
Methods: Acute colitis was induced by treatment of IEX-1 knockout (KO) and wild type (WT) control mice with dextran sulfate sodium (DSS), whereas chronic colitis was induced in Rag-/- mice by adoptive transfer of CD4(+)CD45RB(hi) T cells isolated from the two strains of mice. The diseases and responses of lamina propria lymphocytes were analyzed in the mice.
Results: IEX-1 KO mice produced IL-17 in the colon significantly greater than WT control mice following DSS treatment owing to better survival and differentiation of both IL-17-secreting gamma delta T cells and Th17 cells. The altered level of IL-17 production contributed critically to the reduced colon inflammation in IEX-1 KO mice, and administration of neutralizing anti-IL-17 antibody increased susceptibility of the animal to the disease. Strikingly, in contrast to the better survival of T cells producing IL-17, lack of IEX-1 enhanced apoptosis in proinflammatory T cells producing interferon gamma (IFN-gamma). Enhanced apoptosis in Th1 cells and better survival of Th17 cells may both result in a delayed onset of colitis in Rag-/- mice receiving pathogenic CD4(+)CD45RB(hi) hi T cells isolated from IEX-1 KO animals compared to those mice transferred with WT counterparts
Conclusions: The present study demonstrates the refractoriness of IEX-1 knockout (KO) mice to DSS-induced colitis and diminished pathogenesis of IEX-1-deficient CD4(+)CD45RB(hi) T cells. These data demonstrate that IEX-1 reciprocally regulates T-cell survival and apoptosis in a subset- dependent fashion. Inhibition of IEX-1 may thus offer novel strategies for colitis treatment by simultaneous induction of apoptosis in proinflammatory Th1 cells while promoting the survival and differentiation of a protective T-cell subset.

ID ASTHMA MANAGEMENT; ACCURACY; INTERVENTION
AB Objective. Allergic asthma is common in urban minority children and evidence suggests that remediation tailored to the child's allergic profile is the most effective management strategy. The purpose of this pilot study therefore was to examine the caregiver's recall of their child's skin test results and the accuracy of planned remediation similar to 4 months after testing. Methods. Caregivers were asked to recall their child's skin test results similar to 4 months after their skin testing but before any follow-up visit. A Q-sort was then used to determine the knowledge of the recommended remediation. In this Q-sort, caregivers placed 52 cards, each representing one intervention for an indoor allergen, on a response board that prioritized the interventions. At the conclusion of the Q-sort, caregivers received feedback on the accuracy of their recall and prioritization. Results. African American caregivers (5 females; mean age 33.6) of 5 children (4 males; mean age 7.8) were enrolled. No caregiver's recall of skin test results was concordant with the actual results for type or number of allergens. Caregiver's accuracy in prioritizing strategies was 33-100% for cat dander, 40-70% for molds, 70-87% for dust mite allergens, and 100% for the one dog allergic child. Subjects preferred Q-sort to traditional methods of receiving remediation education. Conclusions. Caregivers do not accurately recall skin test results and this may, in part, impede their ability to implement appropriate interventions. A low-literacy game-style approach is a novel strategy to provide complex teaching that warrants further investigation.

AB Objective: To explore dose-response effects of lisdexamfetamine dimesylate (LDX) treatment for ADHD. Method: This was a 4-week, randomized, double-blinded, placebo-controlled, parallel-group, forced-dose titration study in adult participants, aged 18 to 55 years, meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) criteria for ADHD. Results: Nearly all participants assigned to an LDX dose achieved their assigned dose with the exception of about 4% of participants assigned to the 50 mg or 14% assigned to the 70 mg doses. Higher doses of LDX led to greater improvements in ADHD-rating scale scores, independent of prior pharmacotherapy. This was evident for both inattentive and hyperactive-impulsive symptoms. The authors found some evidence for an interaction between LDX dose and baseline severity of ADHD symptoms. Conclusion: For LDX doses between 30 and 70 mg/d, the dose-response efficacy effect for LDX is not affected by prior pharmacotherapy, but patients with a greater severity of illness may benefit more from higher doses, especially for hyperactive-impulsive symptoms. The results do not provide information about doses above 70 mg/d, which is the maximum approved dose of LDX and the highest dose studied in ADHD clinical trials. (J. of Att. Dis. 2012; 16(2) 118-127)

AB Poly(vinyl alcohol) (PVA) hydrogels have desirable characteristics for use as artificial cartilage, such as biocompatibility, high water content, and surface lubricity. However, PVA hydrogels are not strong enough to withstand the demanding load-bearing environment in human joints. Thermal annealing can greatly improve compressive strength, but it also causes substantial loss in water content and lubricity. We demonstrated that incorporating anionic moieties of poly(acrylic acid) improves surface lubricity, whereas adding poly(ethylene-glycol) prevents pore collapse during thermal annealing, yielding a tough hydrogel with high lubricity. We also found a super-lubricous response from the gels when they were annealed in air versus argon gas. (C) 2011 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater 100B: 524532, 2012.

AB Goals: To describe dermatologic side effects encountered during treatment of patients with chronic hepatitis C, and analyze factors predisposing to such reactions.
Background: Treatment of hepatitis C virus (HCV) infection with interferon (IFN) and ribavirin is associated with a number of mucocutaneous adverse reactions that have not been adequately studied.
Study: A retrospective cohort study design was used to longitudinally describe mucocutaneous drug eruptions during IFN and ribavirin therapy in HCV-infected patients. Factors predictive of mucocutaneous eruptions were analyzed by the use of Kaplan-Meier curves and Cox proportional hazard model.
Results: A total of 286 HCV-infected consecutive patients were treated with one of the IFN alpha formulations plus ribavirin. The mean age was 51.1 years (SD 5.6). There were 6 female patients. There were 5 patients who were also infected with human immunodeficiency virus (HIV). Fifty-six percent of the patients were white, 37% were African American, and 14% were Hispanic. Twenty-one percent of all study patients developed mucocutaneous drug eruptions. The most common drug eruptions were eczematous drug eruptions (48%), seborrheic dermatitis (11%), and xerosis (8%). Dermatologic eruptions were a contributing factor in the decision to discontinue antiviral treatment in 10% of cases. Use of Pegylated IFN formulations (hazard ratio = 1.86; 95% confidence interval, 1.04-3.34) and presence of HIV coinfection (hazard ratio = 4.46; 95% confidence interval, 1.61-12.92) were associated with increased rate of skin reactions.
Conclusions: Mucocutaneous reactions during IFN and ribavirin treatment of hepatitis C are common and are associated with HIV infection and use of Pegylated IFN.

AB Aims: To examine whether overweight and obesity indicators -body mass index (BMI), waist circumference (WC), and WC-to-height ratio -predict progression of periodontal disease in men. Material and Methods: Participants were 1038 medically healthy, non-Hispanic, white males in the VA Dental Longitudinal Study who were monitored with triennial oral and medical examinations between 1969 and 1996. Periodontal disease progression in an individual was defined as having two or more teeth advance to levels of alveolar bone loss >= 40%, probing pocket depth similar to 5 mm, or clinical attachment loss > 5 mm after baseline. Extended Cox regression analyses estimated hazards of experiencing periodontal disease progression events due to overweight/ obesity status, controlling for age, smoking, education, diabetes, recent periodontal treatment, recent prophylaxis, and number of filled/ decayed surfaces. Results: Body mass index and WC-to-height ratio were significantly associated with hazards of experiencing periodontal disease progression events regardless of periodontal disease indicator. Adjusted hazard ratios for periodontal disease progression were 41-72% higher in obese men (BMI >= 30 kg/m(2)) relative to men with both normal weight and WC-to-height ratio (>= 50%). Conclusion: Both overall obesity and central adiposity are associated with an increased hazards of periodontal disease progression events in men.

Critical to changing care is an understanding of the context within which the improvement effort occurs, including the climate or culture. Health care systems are multicultural due to the wide variety of professionals, subgroups, divisions and teams within them. Yet, little work describes and compares different stakeholders' views on their and others' roles in promoting successful quality improvement implementation.

AB Background. Vibrio cholerae excreted by cholera patients is "hyperinfectious'' ( HI), which can be modeled by passage through infant mice. Immunization of adult female mice with V. cholerae outer-membrane vesicles (OMVs) passively protects suckling mice from challenge. Although V. cholerae is unable to colonize protected pups, the bacteria survive passage and have the potential to be transmitted to susceptible individuals. Here, we investigated the impact of OMV immunization and the HI state on V. cholerae transmission.
Methods. Neonatal mice suckled by OMV- or sham-immunized dams were challenged with HI V. cholerae. The infectivity of spatially and temporally separate V. cholerae populations obtained from infected naive or protected pups was tested. Recombination-based in vivo expression technology was used to assess virulence gene expression within these populations.
Results. OMV immunization significantly reduced colonization of neonates challenged with HI V. cholerae. Vibrio cholerae that had colonized the naive host was HI, whereas V. cholerae excreted by neonates born to OMV-immunized dams, although viable, was hypoinfectious and failed to fully induce virulence gene expression.
Conclusions. OMV immunization can significantly reduce the V. cholerae burden upon challenge with HI V. cholerae and can also block transmission from immune mice by reducing the infectivity of shed bacteria.

AB Human adult stem cells (hASCs) offer a potentially renewable source of cell types that are easily isolated and rapidly expanded for use in regenerative medicine and cell therapies without the complicating ethical problems that are associated with embryonic stem cells. However, the eventual therapeutic use of hASCs requires that these cells and their derivatives maintain their genomic stability. There is currently a lack of systematic studies that are aimed at characterising aberrant chromosomal changes in cultured ASCs over time. However, the presence of mosaicism and accumulation of karyotypic abnormalities within cultured cell subpopulations have been reported. To investigate cytogenetic integrity of cultured human dental stem cell (hDSC) lines, we analysed four expanded hDSC cultures using classical G banding and fluorescent in situ hybridisation (FISH) with X chromosome specific probe. Our preliminary results revealed that about 70% of the cells exhibited karyotypic abnormalities including polyploidy, aneuploidy and ring chromosomes. The heterogeneous spectrum of abnormalities indicates a high frequency of chromosomal mutations that continuously arise upon extended culture. These findings emphasise the need for the careful analysis of the cytogenetic stability of cultured hDSCs before they can be used in clinical therapies.

AB Objectives: Femoral reaming and intramedullary nailing (IMN) primes polymorphonuclear leukocytes (PMNL) and thereby increases the posttraumatic systemic inflammatory response. Resuscitation with hypertonic saline (HTS) attenuates PMNL activation after trauma-hemorrhage. We hypothesized that preoperative administration of 7.5% HTS attenuates PMNL priming after IMN of unilateral femur shaft fractures compared with 0.9% normal saline.
Design: Prospective, randomized, double-blind study.
Setting: Level I trauma center.
Patients: Twenty patients between 18 and 80 years of age with an Injury Severity Score less than 25 and a unilateral femur shaft fracture amenable to IMN fixation within 24 hours after injury.
Intervention: Patients were allocated to equally sized HTS or normal saline treatment groups (n = 10) before surgery. Solutions were administered in a blinded bag as a single bolus of 4 mL/kg body weight immediately before surgery. Whole blood samples were collected directly before saline application (t(0)) and at 6, 12, and 24 hours after surgery.
Main Outcome Measurements: PMNL surface expression of CD11b and CD62L, as determined by flow cytometry analysis.
Results: Demographic characteristics of both treatment groups were comparable. Baseline expression of CD11b and CD62L cell markers was in a similar range in the two cohorts. The expression levels of CD11b were comparable between the two groups throughout the observation time, whereas CD62L levels were significantly higher in the HTS group at 6 and 24 hours after surgery.
Conclusion and Significance: Preoperative infusion of HTS appears to exert an anti-inflammatory effect by attenuating the extent of postoperative PMNL activation after reamed IMN for femoral shaft fractures.

AB Target identification is a core challenge in chemical genetics. Here we use chemical similarity to computationally predict the targets of 586 compounds that were active in a zebrafish behavioral assay. Among 20 predictions tested, 11 compounds had activities ranging from 1 nM to 10,000 nM on the predicted targets. The roles of two of these targets were tested in the original zebrafish phenotype. Prediction of targets from chemotype is rapid and may be generally applicable.

AB How bacteria grow and divide while retaining a defined shape is a fundamental question in microbiology, but technological advances are now driving a new understanding of how the shape-maintaining bacterial peptidoglycan sacculus grows. In this Review, we highlight the relationship between peptidoglycan synthesis complexes and cytoskeletal elements, as well as recent evidence that peptidoglycan growth is regulated from outside the sacculus in Gram-negative bacteria. We also discuss how growth of the sacculus is sensitive to mechanical force and nutritional status, and describe the roles of peptidoglycan hydrolases in generating cell shape and of D-amino acids in sacculus remodelling.

AB The relative importance of specific genetic and environmental factors in regulating nicotine dependence (ND) risk, including the effects on specific forms of childhood adversity on smoking risk, have been understudied. Genome-wide association studies and rodent models have demonstrated that the alpha 5 nicotinic acetylcholine receptor gene (CHRNA5) is important in regulating nicotine intake. Childhood adversity increases the methylation level of the CHRNA5 promoter region in European Americans (EAs), an effect that was observed only in males (Zhang et al, submitted for publication). In view of this potential sex difference in the effects of early life experience on smoking, we investigated the presence of a sex-specific gene-by-environment effect of this marker on ND risk. A nonsynonymous SNP in CHRNA5 previously associated to ND and several related traits, rs16969968, was genotyped in 2206 EAs (1301 men and 905 women). The main and interactive effects of childhood adversity and rs16969968 genotype on diagnosis of ND and ND defined by dichotomized Fagerstrom test for ND (FTND) scores were explored. Men and women were analyzed separately to test for sex differences. Childhood adversity significantly increased ND risk in both sexes, and the effect in women was twice than that in men. Significant interactive effects of childhood adversity and rs16969968 genotype were observed in men (ND: OR = 1.80, 95% CI = 1.18-2.73, P = 0.0044; FTND: OR = 1.79, 95% CI = 1.11-2.88, P = 0.012). No interaction was found in women. This study provides evidence of a sex-specific gene x environment effect of CHRNA5 and childhood adversity on the risk for ND.

AB Serotonin reuptake inhibitors and cognitive-behavior therapy (CBT) are considered first-line treatments for obsessive-compulsive disorder (OCD). However, little is known about their modulatory effects on regional brain morphology in OCD patients. We sought to document structural brain abnormalities in treatment-naive OCD patients and to determine the effects of pharmacological and cognitive-behavioral treatments on regional brain volumes. Treatment-naive patients with OCD (n = 38) underwent structural magnetic resonance imaging scan before and after a 12-week randomized clinical trial with either fluoxetine or group CBT. Matched-healthy controls (n = 36) were also scanned at baseline. Voxel-based morphometry was used to compare regional gray matter (GM) volumes of regions of interest (ROIs) placed in the orbitofrontal, anterior cingulate and temporolimbic cortices, striatum, and thalamus. Treatment-naive OCD patients presented smaller GM volume in the left putamen, bilateral medial orbitofrontal, and left anterior cingulate cortices than did controls (p<0.05, corrected for multiple comparisons). After treatment with either fluoxetine or CBT (n = 26), GM volume abnormalities in the left putamen were no longer detectable relative to controls. ROI-based within-group comparisons revealed that GM volume in the left putamen significantly increased (p<0.012) in fluoxetine-treated patients (n = 13), whereas no significant GM volume changes were observed in CBT-treated patients (n = 13). This study supports the involvement of orbitofronto/cingulo-striatal loops in the pathophysiology of OCD and suggests that fluoxetine and CBT may have distinct neurobiological mechanisms of action.

AB Pediatric gastrointestinal stromal tumor (GIST) is a rare entity that can be quite different from its adult counterpart. This report provides a comprehensive review on the diagnosis and management of this tumor in children and adolescents, including its oncogenesis and associated syndromes. Surgery remains a mainstay of treatment, but there are no standard guidelines available at this time regarding the best practice for multimodality therapy as our understanding of the biology of GIST is still in evolution. Therefore, pediatric patients with GIST should be ideally treated in the context of clinical trials at specialized, multidisciplinary centers throughout the course of their disease, especially because these patients may live for years after diagnosis.

AB Protein S deficiency is a thrombophilia associated with increased risk of thromboembolic episodes in affected patients. Traditionally, protein S deficiency in a potential donor was considered an absolute contraindication to living donor liver transplantation, both due to the increased risk incurred by the thrombophilic donor as well as the risk of transmitting the thrombophilia to the liver recipient, as protein S is predominantly produced by the liver. We present the first successful case of living donor liver transplantation using a donor with asymptomatic protein S deficiency. Interestingly, whereas the donor continued to have protein S levels approximately 50% of normal, the recipient maintained normal levels of protein S post-transplant, potentially due to compensation by extra-hepatic protein S production. We discuss the prior literature of protein S deficiency acquired via liver transplantation, and we evaluate potential criteria by which the safety of transplants utilizing this pool of donors may be enhanced.

AB Objective: This study sought to examine the age-dependent persistence of attention deficit hyperactivity disorder (ADHD) and its predictors in a large sample of girls with and without ADHD followed prospectively for 11 years into young adulthood.
Method: Participants were girls with (N = 96) and without (N = 91) ADHD and were 6-17 years old at the baseline assessment (mean age, 11 years) and 15-30 years old at the follow-up assessment (mean: 22 years). Participants were comprehensively and blindly assessed with structured diagnostic interviews and assessments of cognitive, social, school, and family functioning.
Results: At the 11-year follow-up, 33.3% met full criteria for ADHD, 29.2% showed partial persistence of the disorder, 10.4% had impaired functioning, and 4.2% were remitted but treated (77.1% of the sample). Predictors of persistence were psychiatric comorbidity, family history of psychopathology, and family and school functioning at baseline.
Conclusion: These long-term, prospective, follow-up findings extend to girls findings that ADHD is persistent over the long term and can be predicted from psychosocial adversity and psychiatric comorbidity ascertained 11 years earlier.

AB Background With the high prevalence of musculoskeletal disorders (MSDs) for patient care unit workers, prevention efforts through ergonomic practices within units may be related to symptoms associated with typical work-related MSDs.
Methods We completed a cross-sectional survey of patient care workers (n = 1,572) in two large academic hospitals in order to evaluate relationships between self-reported musculoskeletal pain, work interference due to this pain, and limitations during activities of daily living (functional limitations) and with ergonomic practices and other organizational policy and practices metrics within the unit. Bivariate and multiple logistic regression analyses tested the significance of these associations.
Results Prevalence of self-reported musculoskeletal symptoms in the past 3 months was 74% with 53% reporting pain in the low back. 32.8% reported that this pain interfered with their work duties and 17.7% reported functional limitations in the prior week. Decreased ergonomic practices were significantly associated with reporting pain in four body areas (low back, neck/shoulder, arms, and lower extremity) in the previous 3 months, interference with work caused by this pain, symptom severity, and limitations in completing activities of daily living in the past week. Except for low back pain and work interference, these associations remained significant when psychosocial covariates such as psychological demands were included in multiple logistic regressions.
Conclusions Ergonomic practices appear to be associated with many of the musculoskeletal symptoms denoting their importance for prevention efforts in acute health care settings. Am. J. Ind. Med. 55: 107-116, 2012. (C) 2011 Wiley Periodicals, Inc.

AB Background Patient care workers in acute care hospitals are at high risk of injury. Recent studies have quantified risks and demonstrated a higher risk for aides than for nurses. However, no detailed studies to date have used OSHA injury definitions to allow for better comparability across studies.
Methods We linked records from human resources and occupational health services databases at two large academic hospitals for nurses (n = 5,991) and aides (n 1,543) in patient care units. Crude rates, rate ratios, and confidence intervals were calculated for injuries involving no days away and those involving at least 1 day away from work.
Results Aides have substantially higher injury rates per 100 full-time equivalent workers (FTEs) than nurses for both injuries involving days away from work (11.3 vs. 7.2) and those involving no days away (9.9 vs. 5.7). Back injuries were the most common days away (DA) injuries, while sharps injuries were the most common no days away (NDA) injuries. Pediatric/neonatal units and non-inpatient units had the lowest injury rates. Operating rooms and the float pool had high DA injury rates for both occupations, and stepdown units had high rates for nurses. NDA injuries were highest in the operating room for both nurses and aides.
Conclusions This study supports the importance of a continuing emphasis on preventing back and sharps injuries and reducing risks faced by aides in the hospital setting. Uniform injury definitions and work time measures can help benchmark safety performance and focus prevention efforts. Am. J. Ind. Med. 55: 117-126, 2012. (C) 2011 Wiley Periodicals, Inc.

AB Objective The objective of this report is to compare baseline, management and survival characteristics in idiopathic pulmonary arterial hypertension (IPAH) with systemic sclerosis-associated pulmonary arterial hypertension (SSc-APAH) using data from the prospectively enrolled PAH Quality Enhancement Research Initiative.
Methods Between August 2005 and July 2007, patients with IPAH and SSc-APAH were enrolled across 60 US sites and followed up for 3 years. Data on diagnostic tests, clinical variables, pulmonary arterial hypertension (PAH) medication and outcomes were recorded.
Results With some exceptions, baseline clinical and laboratory characteristics were similar between the 279 patients with IPAH and the 228 with SSc-APAH. Patients with SSc-APAH were older at the time of PAH diagnosis, were more likely to be female and were antinuclear antibody positive. Patients with SSc-APAH had poorer spirometric results. During the 3-year follow-up, both groups were managed with prostacyclin and prostacyclin analogue treatment, endothelin receptor antagonists and phosphodiesterase type 5 inhibitors (PDE5i) singly or in combination. At 3 years, patients with SSc-APAH were more likely to be treated with PDE5i alone or with an endothelin receptor antagonist. Patients with SSc-APAH had a significantly lower survival rate compared to patients with IPAH (60% vs 77%, p<0.0001).
Conclusions The cohort with SSc-APAH was older, was more severely ill, was more likely to be female, was managed with PDE5i and had reduced 3-year survival compared with the cohort with IPAH.

AB Objective Reduced growth hormone (GH) secretion is observed in obesity and may contribute to increases in cardiovascular disease (CVD) risk. Lipoprotein characteristics including increased small dense low-density lipoprotein (LDL) particles are known independent risk factors for CVD. We hypothesized that reduced GH secretion in obesity would be associated with a more atherogenic lipid profile including increased small dense LDL particles.

AB The clinical value of measuring C-reactive protein (CRP) to guide statin therapy is uncertain. It has no value in patients at high risk who would be treated regardless of CRP (eg, patients with coronary disease or of equivalent risk), in patients at low risk who do not warrant treatment, and those with other acute or chronic inflammatory conditions that amplify CRP. Drawbacks to the widespread clinical use of CRP include its small impact on risk prediction beyond other risk factors, and evidence from JUPITER and other trials that baseline CRP is unable to identify patients who obtain greater absolute benefits from statin therapy. Furthermore, the within-person variability of CRP is about the same as the reduction in CRP from intensive statin therapy, and this leads to many patients registering an increase in CRP with treatment. For these reasons, CRP has no clear role in determining who should receive statin therapy or for monitoring the success of treatment.

AB High-density lipoprotein (HDL) cholesterol levels bear an inverse relationship to cardiovascular risk. To date, however, no intervention specifically targeting HDL has been demonstrated to reduce cardiovascular risk. Cholesterol ester transfer protein (CETP) mediates transfer of cholesterol ester from HDL to apolipoprotein B-containing particles. Most, but not all observational cohort studies indicate that genetic polymorphisms of CETP associated with reduced activity and higher HDL cholesterol levels are also associated with reduced cardiovascular risk. Some, but not all studies indicate that CETP inhibition in rabbits retards atherosclerosis, whereas transgenic CETP expression in mice promotes atherosclerosis. Torcetrapib, the first CETP inhibitor to reach phase III clinical development, was abandoned due to excess mortality associated with increases in aldosterone and blood pressure. Two other CETP inhibitors have entered phase III clinical development. Anacetrapib is a potent inhibitor of CETP that produces very large increases in HDL cholesterol and large reductions in low-density lipoprotein (LDL) cholesterol, beyond those achieved with statins. Dalcetrapib is a less potent CETP inhibitor that produces smaller increases in HDL cholesterol with minimal effect on LDL cholesterol. Both agents appear to allow efflux of cholesterol from macrophages to HDL in vitro, and neither agent affects blood pressure or aldosterone in vivo. Two large cardiovascular outcomes trials, one with anacetrapib and one with dalcetrapib, should provide a conclusive test of the hypothesis that inhibition of CETP decreases cardiovascular risk.

AB Diabetes affects approximately one quarter of all hospitalized patients. Poor inpatient glycemic control has been associated with increased risk for multiple adverse events including surgical site infections, prolonged hospital length of stay, and mortality. Inpatient glycemic control protocols based on physiologic basal-bolus insulin regimens have been shown to improve glycemia and clinical outcomes and are recommended by the American Diabetes Association, the American Association of Clinical Endocrinologists, and the Society of Hospital Medicine for inpatient glycemic management of noncritically ill patients. The 2009 Health Information Technology for Economic and Clinical Health (HITECH) Act will catalyze widespread computerized medication order entry implementation over the next few years. Here, we focus on the noncritical care setting and review the background on inpatient glycemic management as it pertains to computerized order entry, the translation and efficacy of computerizing glycemic control protocols, and the barriers to computerizing glycemic protocols.

AB Purpose of review
The diagnosis of growth hormone deficiency (GHD) in childhood is challenging, in large part because of the lack of a true gold standard and the relatively poor performance of available diagnostic testing. This review discusses the recent literature on this topic.
Recent findings
Auxology and clinical judgment remain the foundation for the diagnosis of GHD. Provocative growth hormone testing is poorly reproducible, dependent on factors such as body composition and pubertal status, and further limited by significant variability among commercially available growth hormone assays. Measurement of insulin-like growth factor I and insulin-like growth factor-binding protein 3 is not diagnostically useful in isolation but is helpful in combination with other diagnostic measures. Neuroimaging is also useful to inform diagnosis, as pituitary abnormalities suggest a higher likelihood of GHD persisting into adulthood. Although genetic testing is not routinely performed in the diagnosis of GHD at the present time, multiple recent reports raise the possibility that it may play a more important role in diagnosing GHD in the future.
Summary
Beyond physicians' integrated assessment of auxology, clinical presentation, and bone age, current tools to diagnose GHD are suboptimal. Recent literature emphasizes the need to reappraise our current practice and to consider new tools for diagnosis.

DESIGN
AB Common genetic variants have been associated with type 2 diabetes. We hypothesised that a subset of these variants may have different effects on the transition from normal fasting glucose (NFG) to impaired fasting glucose (IFG) than on that from IFG to diabetes.
We identified 16 type 2 diabetes risk variants from the Illumina Broad Candidate-gene Association Resource (CARe) array genotyped in 26,576 CARe participants. Participants were categorised at baseline as NFG, IFG or type 2 diabetic (n = 16,465, 8,017 or 2,291, respectively). Using Cox proportional hazards and likelihood ratio tests (LRTs), we compared rates of progression by genotype for 4,909 (NFG to IFG) and 1,518 (IFG to type 2 diabetes) individuals, respectively. We then performed multinomial regression analyses at baseline, comparing the risk of assignment to the NFG, IFG or diabetes groups by genotype.
The rate of progression from NFG to IFG was significantly greater in participants carrying the risk allele at MTNR1B (p = 1 x 10(-4)), nominally greater at GCK and SLC30A8 (p < 0.05) and nominally smaller at IGF2BP2 (p = 0.01) than the rate of progression from IFG to diabetes by the LRT. Results of the baseline, multinomial regression model were consistent with these findings.
Common genetic risk variants at GCK, SLC30A8, IGF2BP2 and MTNR1B influence to different extents the development of IFG and the transition from IFG to type 2 diabetes. Our findings may have implications for understanding the genetic contribution of these variants to the development of IFG and type 2 diabetes.

ID EXPERIENCE; INJURY
AB Objectives To assess the incidence and degree of MRI contrast enhancement in liver tumours following successful percutaneous cryoablation.
Methods Thirty-eight patients with liver metastases (n = 29) or hepatocellular carcinoma (n = 9) underwent percutaneous cryoablation of 45 tumours between March 2004 and June 2009, with complete ablation zone coverage of the tumour and no local recurrence on follow-up imaging to date (range 3-60 months, mean 16). Contrast-enhanced MRI was used to assess 45 tumours at 24 h, 32 tumours at 2-4 months, and 21 tumours at 5-7 months. Percentage of tumours with contrast enhancement was assessed using dynamic spoiled gradient echo T1-weighted images.
Results Twenty-four hours post-cryoablation, 23 out of 45 tumours (51%) enhanced compared with 42 out of 43 (98%) pre-ablation (p < 0.001). Mean percentage tumour enhancement decreased from 157% (range 26-745%) pre-ablation, to 107% (27-260%) at 24 h (p = 0.003), and 43% (24-103%) at 2-4 months (p < 0.001). The incidence and degree of tumour enhancement decreased through 5-7 months.
Conclusions Unlike previously reported studies of radiofrequency ablation, successful cryoablation of liver tumours is often associated with persistent tumour contrast enhancement on MRI performed at 24 h and decreasing over 2-7 months.
Key Points
Liver neoplasms often demonstrate MRI contrast enhancement following successful percutaneous cryoablation.
This differs from radiofrequency ablation techniques where contrast enhancement suggests residual tumour
This difference could potentially lead to important errors in follow up strategies.

AB Context: The expanding armamentarium of agents for the therapy of advanced clear cell renal cell carcinoma (RCC) warrants further investigation of optimal patient selection.
Objective: To analyze the second and subsequent line of targeted therapies for advanced RCC while integrating clinical and molecular markers and imaging.
Evidence acquisition: Data were acquired from research published in peer-reviewed literature or presented at major conferences.
Evidence synthesis: Following first-line vascular endothelial growth factor (VEGF) inhibitors, second-line therapy with everolimus, a mammalian target of rapamycin inhibitor, and axitinib, a VEGF receptor tyrosine kinase inhibitor, have demonstrated benefits in progression-free survival (PFS). Sorafenib, pazopanib, and axitinib have demonstrated extension of PFS following cytokines. Optimal patient selection based on biomarkers is undergoing investigation. Clinical trials evaluating novel agents and combinations should be preferred.
Conclusions: Currently, the sequence of therapy is based on patient and physician decision, which may be influenced by comorbidities and toxicity profiles. (C) 2011 European Association of Urology. Published by Elsevier B. V. All rights reserved.

AB Background and aims Shorter telomeres have been associated with increased risk of malignancy, including colorectal cancer (CRC). Telomere length is heritable and may be an intermediate phenotype linked to genetic susceptibility to CRC.
Methods In a large sample, the study investigated whether candidate single nucleotide polymorphisms (SNP) in 'telomere biology' genes were associated with telomere length in leucocytes. SNP associated with an increased risk of CRC were searched for separately.
Results Carriers of the common allele at SNP rs10936599, near the telomerase RNA component (TERC) locus, had significantly longer telomeres. It was independently found that the same rs10936599 allele was associated with increased risk of both CRC and colorectal adenomas. Neither telomere length nor CRC risk was associated with variation near telomerase reverse transcriptase or other telomere biology genes. In silico analysis showed that SNP rs2293607 was strongly correlated with rs10936599, mapped within TERC transcripts, had a predicted effect on messenger RNA folding and lay at a reported transcription factor binding site. TERC mRNA were expressed, differing only at the alleles of rs2293607, in CRC cell line HCT116. The long-telomere/CRC-risk allele was associated with higher levels of TERC mRNA and the formation of longer telomeres.
Conclusions Common genetic variation at TERC is associated with both longer telomeres and an increased risk of CRC, a potential mechanism being reduced levels of cell senescence or death. This finding is somewhat paradoxical, given retrospective studies reporting that CRC cases have shorter telomeres than controls. One possibility is that that association actually results from poorer survival in patients with longer telomeres.

AB Objective. The aim of this study was to measure the relationship between days spent waiting for primary care and health outcomes among patients diagnosed with diabetes, especially among the elderly population.
Data Source. Secondary data from VA administrative databases and Medicare claims.
Study Design. This is a retrospective observational study. Outcome variables include primary care utilization, mortality, heart attack, stroke, and ambulatory-care sensitive condition (ACSC) hospitalization. The main explanatory variable of interest is VA primary care wait time. Negative binomial models predict utilization and stacked logistic regression models predict the probability of experiencing each health outcome. Models are stratified by the presence of a selected health condition and age.
Principal Findings. Longer wait times were predicted to decrease utilization between 2 and 4 percent. There was no significant relationship between wait times and health outcomes for the overall sample. In stratified analyses, longer waits were associated with undesirable outcomes for those over age 70 with one of the selected health conditions or in certain narrower 5-year age groups, but the overall pattern of results does not indicate a systematic and significant effect.
Conclusions. There was a modest effect of long wait times on primary care utilization but no robust effect of longer wait times on health outcomes. Waiting for care did not significantly compromise long-term health outcomes for veterans with diabetes.

AB Stimulus-frequency otoacoustic emissions (SFOAEs) have been used to study a variety of topics in cochlear mechanics, although a current topic of debate is where in the cochlea these emissions are generated. One hypothesis is that SFOAE generation is predominately near the peak region of the traveling wave. An opposing hypothesis is that SFOAE generation near the peak region is deemphasized compared to generation in the tail region of the traveling wave. A comparison was made between the effect of low-frequency biasing on both SFOAEs and a physiologic measure that arises from the peak region of the traveling wave-the compound action potential (CAP). SFOAE biasing was measured as the amplitude of spectral sidebands from varying bias tone levels. CAP biasing was measured as the suppression of CAP amplitude from varying bias tone levels. Measures of biasing effects were made throughout the cochlea. Results from cats show that the level of bias tone needed for maximum SFOAE sidebands and for 50% CAP reduction increased as probe frequency increased. Results from guinea pigs show an irregular bias effect as a function of probe frequency. In both species, there was a strong and positive relationship between the bias level needed for maximum SFOAE sidebands and for 50% CAP suppression. This relationship is consistent with the hypothesis that the majority of SFOAE is generated near the peak region of the traveling wave.

AB Objectives: A cross-sectional study examined how race and sex affect associations among osteoarthritis (OA) pain, disability, and depression in 363 older adults with diagnosed knee OA. Method: African American (Black; N = 94) and non-Hispanic White (White; N = 269) men and women self-reported pain, disability, depressive symptoms, arthritis history, general health, and demographic information. Results: Women experienced greater pain and marginally greater disability than men; African Americans reported greater disability and marginally greater pain than non-Hispanic Whites. These effects varied with education, health, and arthritis history. In ordinary least squares regression analyses, race and pain independently predicted depression. Significant interactions of race, sex, and disability were driven by a lack of relationship between depression and disability among African American men. Discussion: Race and sex influence affective response to OA pain and disability in complex ways, with African American men showing paradoxical effects. Further research is needed to elucidate mechanisms of this moderation effect.

SO JOURNAL OF CELLULAR PHYSIOLOGY

DT Article
ID STEM-CELL NICHE; PARATHYROID-HORMONE; IN-VIVO; DIFFERENTIATION; ARREST;

AB Bone is maintained by continuous bone formation by osteoblasts provided by proliferation and differentiation of osteoprogenitors. Parathyroid hormone (PTH) activates bone formation, but because of the complexity of cells in the osteoblast lineage, how these osteoprogenitors are regulated by PTH in vivo is incompletely understood. To elucidate how signals by PTH in differentiated osteoblasts regulate osteoprogenitors in vivo, we conducted bone marrow ablation using Col1a1-constitutively active PTH/PTHrP receptor (caPPR) transgenic mice. These mice express caPPR specifically in osteoblasts by using 2.3kb Col1a1 promoter and showed higher trabecular bone volume under steady-state conditions. In contrast, after bone marrow ablation, stromal cells recruited from bone surface extensively proliferated in the marrow cavity in transgenic mice, compared to limited proliferation in wild-type mice. Whereas de novo bone formation was restricted to the ablated area in wild-type mice, the entire marrow cavity, including not only ablated area but also outside the ablated area, was filled with newly formed bone in transgenic mice. Bone mineral density was significantly increased after ablation in transgenic mice. Bone marrow cell culture in osteogenic medium revealed that alkaline phosphatase-positive area was markedly increased in the cells obtained from transgenic mice. Furthermore, mRNA expression of Wnt-signaling molecules such as LRP5, Wnt7b, and Wnt10b were upregulated after marrow ablation in bone marrow cells of transgenic mice. These results indicate that constitutive activation of PTH/PTHrP receptor in differentiated osteoblasts enhances bone marrow ablation-induced recruitment, proliferation, and differentiation of osteoprogenitors.

AB Orthopedic gene therapy has been the topic of considerable research for two decades. The preclinical data are impressive and many orthopedic conditions are well suited to genetic therapies. But there have been few clinical trials and no FDA-approved product exists. This paper examines why this is so. The reasons are multifactorial. Clinical translation is expensive and difficult to fund by traditional academic routes. Because gene therapy is viewed as unsafe and risky, it does not attract major funding from the pharmaceutical industry. Start-up companies are burdened by the complex intellectual property environment and difficulties in dealing with the technology transfer offices of major universities. Successful translation requires close interactions between scientists, clinicians and experts in regulatory and compliance issues. It is difficult to create such a favorable translational environment. Other promising fields of biological therapy have contemplated similar frustrations approximately 20 years after their founding, so there seem to be more general constraints on translation that are difficult to define. Gene therapy has noted some major clinical successes in recent years, and a sense of optimism is returning to the field. We hope that orthopedic applications will benefit collaterally from this upswing and move expeditiously into advanced clinical trials. J. Cell. Physiol. 227: 416420, 2012.

AB Blood-borne nucleated cells participate not only in inflammation, but in tissue repair and regeneration. Because progenitor and stem cell populations have a low concentration in the blood, the circulation kinetics and tissue distribution of these cells is largely unknown. An important approach to tracking cell lineage is the use of fluorescent tracers and parabiotic models of cross-circulation. Here, we investigated the cross-circulation and cell distribution kinetics of C57/B6 GFP+/wild-type parabionts. Flow cytometry analysis of the peripheral blood after parabiosis demonstrated no evidence for a parabiotic barrier based on cell size or surface characterstics; all peripheral blood cell subpopulations in this study reached equilibrium within 14 days. Whole blood fluorescence analysis indicated that the mean exchange flow rate was 16 mu l/h or 0.66% of the circulating blood volume per hour. Studies of peripheral lymphoid organs indicated differential cell distribution kinetics. Some subpopulations, such as CD8+ and CD11c+, equilibrated in both lymph nodes and spleen indicating a residence time <28 days; in contrast, other lymphocyte subpopulations, such as B220+ and CD4+ cells, had not yet reached equilibrium at 28 days. We conclude that parabiosis can provide important insights into defining tissue distribution, residence times, and recirculating pools using fluorochrome markers of cell lineage. J. Cell.

AB Stroke survivors are at high risk for cardiovascular mortality which can be in part mitigated by increasing physical activity. Self-efficacy for exercise is known to play a role in adoption of exercise behaviors. This study examines self-reported psychological outcomes in a group of 64 stroke survivors randomized to either a 6-month treadmill training program or a stretching program. Results indicated that, regardless of group, all study participants experienced increased self-efficacy (F = 2.95, p = .09) and outcome expectations for exercise (F = 13.23, p < 0.001) and improvements in activities of daily living as reported on the Stroke Impact Scale (F = 10.97, p = .002). No statistically significant between-group differences were noted, possibly because of the fact that specific interventions designed to enhance efficacy beliefs were not part of the study. Theoretically based interventions should be tested to clarify the role of motivation and potential influence on exercise and physical activity in the stroke survivor population.

AB During monolayer culture, articular chondrocytes dedifferentiate into fibroblast-like cells. The mechanisms underlying this process are poorly understood. We sought to further characterize dedifferentiation by identifying an extended panel of genes that distinguish articular cartilage from dedifferentiated chondrocytes. Thirty-nine candidate marker-genes were identified from previous studies on articular-cartilage gene-expression. Real-time PCR was used to evaluate the mRNA levels for these candidates in calf articular cartilage and dedifferentiated articular chondrocytes. Twenty-two of the candidate marker genes exhibited at least a two-fold difference in gene expression in the two cell types. Twelve of these genes had at least a ten-fold difference in gene expression. Tenascin C (TNC), type I collagen (COL1A1), and hypoxia-inducible factor 1 alpha (HIF1a) showed the highest relative expression levels in dedifferentiated chonodrocytes. Type II collagen (COL2A1), type XI collagen (COL11A2), and superficial zone protein (SZP) showed the highest relative expression levels in articular cartilage. In contrast to previous findings, fibromodulin mRNA, and protein levels were higher in dedifferentiated chondrocytes. Compared to smaller subsets of markers, this panel of 12 highly differentially expressed genes may more precisely distinguish articular cartilage from dedifferentiated chondrocytes. Since many of the genes up-regulated in dedifferentiated chondrocytes are also expressed during cartilage development, dedifferentiated chondrocytes may possess features of cartilage precursor cells.

AB Purpose: Radical cystectomy has been the standard treatment for muscle invasive bladder cancer. Combined modality therapy involving transurethral bladder tumor resection, external beam radiation and chemotherapy is an effective alternative to cystectomy in selected patients. Salvage cystectomy is reserved for those in whom combined modality therapy fails. We characterized complications associated with salvage cystectomy.
Materials and Methods: From 1986 to 2007 of 348 patients undergoing bladder sparing therapy 102 (29%) underwent salvage cystectomy, 91 of whom were treated at Massachusetts General Hospital after receiving combined modality therapy for T2-T4aNxM0 bladder cancer. Patients underwent transurethral bladder tumor resection followed by chemoradiation (40 Gy). Early assessment was performed by cystoscopy/re-biopsy. Patients with complete response continued with consolidation chemoradiation (total dose 64 Gy). Immediate salvage cystectomy (50 of 91) was performed for persistent disease, while delayed salvage cystectomy (41 of 91) was performed for an invasive recurrence. Complications were classified using the Clavien system.
Results: Median patient age was 69.4 years (range 27.5 to 88.9) and median living patient followup was 12 years (range 0 to 23). Of the patients 99% (90 of 91) underwent ileal diversion. Complications of any grade within 90 days occurred in 69% (63 of 91) of patients and 16% (15 of 91) experienced major complications within 90 days. Of the patients 21% (19 of 91) required hospital readmission within 90 days. The 90-day mortality rate was 2.2% (2 of 91). Significant cardiovascular/hematological complications (pulmonary embolism, myocardial infarction, deep vein thrombosis, transfusion) within 90 days were more common in the immediate than in the delayed cystectomy group (37% vs 15%, p = 0.02). Tissue healing complications (fascial dehiscence, wound infection, ureteral stricture, anastomotic stricture, stoma/loop revisions) were more common in the delayed than in the immediate cystectomy group (35% vs 12%, p = 0.05).
Conclusions: Salvage cystectomy is associated with acceptable morbidity, although complication rates are slightly higher than for other cystectomy series. Immediate cystectomies have more cardiovascular/hematological complications while delayed cystectomies have more tissue healing complications.

AB p27Kip1 cleavage and caspase-3 regulate cell cycle in human myeloma cells and B cells, however regulation of p27Kip1 cleavage during the cell cycle is not known. In BaF3-FLT3-ITD cells, p27Kip1 undergoes C-terminal cleavage. Inhibition of the PI3K/AKT pathway is associated with decreased cleavage of p27Kip1 and G1 phase arrest. A caspase-3 inhibitor reduces p27Kip1 cleavage and inhibits cell proliferation. Knockdown shRNA against AKT1 reduces cleavage of p27Kip1, inhibits caspase-3 activation, and is associated with a delay in cell cycle progression. Taken together, these findings indicate that AKT1 induces caspase-mediated cleavage of p27Kip1, required for G1-S progression in FLT3-ITD cells. (C) 2011 Elsevier Ltd. All rights reserved.

AB Patients with acute myeloid leukemia (AML) and a FLT3 internal tandem duplication (ITD) mutation have a poor prognosis, and FLT3 inhibitors are now under clinical investigation. PIM1, a serine/threonine kinase, is up-regulated in FLT3-ITD AML and may be involved in FLT3-mediated leukemogenesis. We employed a PIM1 inhibitor, AR00459339 (Array Biopharma Inc.), to investigate the effect of PIM1 inhibition in FLT3-mutant AML. Like FLT3 inhibitors, AR00459339 was preferentially cytotoxic to FLT3-ITD cells, as demonstrated in the MV4-11, Molm-14, and TF/ITD cell lines, as well as 12 FLT3-ITD primary samples. Unlike FLT3 inhibitors, AR00459339 did not suppress phosphorylation of FLT3, but did promote the dephosphorylation of downstream FLT3 targets, STAT5, AKT, and BAD. Combining AR00459339 with a FLT3 inhibitor resulted in additive to mildly synergistic cytotoxic effects. AR00459339 was cytotoxic to FLT3-ITD samples from patients with secondary resistance to FLT3 inhibitors, suggesting a novel benefit to combining these agents. We conclude that PIM1 appears to be closely associated with FLT3 signaling, and that inhibition of PIM1 may hold therapeutic promise, either as monotherapy, or by overcoming resistance to FLT3 inhibitors.

AB To characterize the roles of tribble 2 (TRB2) and its targeted microRNAs (miRNAs) in the pathogenesis of the early vascular injury involved in diabetic-2 rat. Goto-Kakizaki (GK) rat and Wistar rat were used as the animal models. Each eligible rat was killed and the rat aorta tissues were analyzed by immunohistochemistry, ELISA, reverse transcription-polymerase chain reaction (RT-PCR), and real-time PCR detection. GFP expression in RAOEC cells (rat vascular aortic endothelial cell)were detected by flow cytometry and fluorescent microscope. TRB2 gene expression was increased in endothelia cell and the adventitia of Goto-Kakizaki (GK) rat compared with Wistar rat. Next, studies using RAOEC cells showed that the TRB2 expression was inhibited by the treatment of miR-98. We further showed that the expression of miR-98 was significantly decreased in the adventitia and endomembrane at different degrees in GK rats compared with control. Finally, we validated the changes in TRB2 by studying one of the TRB2's substrates, Akt, in animal models. We expected a corresponding change in the levels of phosphorylated Akt. Indeed, our results showed that the phosphorylation of Akt at Thr 308 in the endothelial cells and phosphorylation of Akt at Ser 473 in adventitia was decreased in GK rats, compared with Wistar control. TRB2 plays important roles in the pathogenesis of diabetic-2 large artery complications at early stage, and these effects may be modulated by miR-98. Thus, targeting TRB2 and miR-98 could be considered as novel therapeutic strategies for the early large artery deficits in diabetic-2.

AB The Alzheimer amyloid protein precursor (APP) is subject to proteolysis by ADAM10 and ADAM17, precluding the formation of A beta. Recently, coding variations in ADAM10 resulting in altered function have been reported in familial Alzheimer disease (AD). The authors carried out a large-scale (n = 576: Controls, 271; AD, 305) resequencing study of ADAM10 in sporadic AD. The results do not support a significant role for ADAM10 mutations in AD. The results also make it clear that the careful examination of ancestry required in any case-control comparison is especially true with rare variations, where even a very small number of variations might form the basis of scientific conclusions.

AB Pesticide exposure is a risk factor of Alzheimer's disease (AD). However, little is known about how pesticide exposure may promote AD pathogenesis. In this study, we investigated the effects of paraquat pesticide exposure on beta-amyloid (A beta) levels and cognition using wild-type (WT) mice and beta-amyloid precursor protein (APP) transgenic mice. Our results showed that wild-type mice and APP transgenic mice after paraquat exposure had increased oxidative damage specifically in mitochondria of cerebral cortex and exhibited mitochondrial dysfunction. Moreover, the elevated mitochondrial damage was directly correlated with impaired associative learning and memory and increased A beta levels in APP transgenic mice exposed to paraquat. Furthermore, overexpression of peroxiredoxin 3, a mitochondrial antioxidant defense enzyme important for H2O2 removal, protected against paraquat-induced mitochondrial damage and concomitantly improved cognition and decreased A beta levels in APP transgenic mice. Therefore, our results demonstrate that mitochondrial damage is a key mechanism underlying cognitive impairment and elevated amyloidogenesis induced by paraquat and that enhanced removal of mitochondrial H2O2 could be an effective strategy to ameliorate AD pathogenesis induced by pesticide exposure.

AB Background Circulating endothelial cells (CECs) have been detected at increased numbers in patients with solid cancers. CECs have not been systematically evaluated in patients with osteosarcoma. Procedure. Patients 12 months to 30 years of age with newly diagnosed high-grade osteosarcoma were eligible for this prospective cohort study. Patients provided a single blood sample at study entry for CEC quantification by flow cytometry at a single reference laboratory. CECs were defined as CD146+, CD31+, CD45-, and CD133-. CEC progenitor cells (CEPs) were defined as CD146+, CD31+, CD45-, and CD133+. Results. Eighteen patients enrolled (11 males; median age 16 years; range 5-21 years). CEC counts did not differ between patients with osteosarcoma compared to seven pediatric healthy controls (median 645 cells/ml, range 60-5,320 cells/ml vs. 1,670 cells/ml, range 330-4,700 cells/ml, respectively; P 0.12). CEP counts did not differ between patients compared to controls (median 126 cells/ml, range 0-5,320 cells/ml vs. median 260 cells/ml, range 0-10,670 cells/ml, respectively; P 0.69). CEC and CEP counts did not correlate with metastatic status, tumor size, or histologic response to neoadjuvant chemotherapy. Conclusions. CEC and CEP levels are not increased in patients with osteosarcoma compared to healthy controls. CECs and CEPs do not correlate with clinical features of osteosarcoma. Alternative novel markers of disease burden and response are needed in this disease. Pediatr Blood Cancer 2012; 58: 181-184. (C) 2011 Wiley Periodicals, Inc.

ID PURPURA; CHILDREN; ADULTS; CHILDHOOD; GUIDELINES
AB Background Since pediatric immune thrombocytopenia (ITP) is relatively infrequent, comparisons among clinical studies are critical but have previously been limited by differences in terminology. In 2009, an international working group (IWG) developed consensus criteria to enhance comparability in future studies in adults and children. Methods. We performed a retrospective medical record review of all pediatric ITP patients seen at a single children's hospital with a first visit between 2003 and 2010 and ;applied both historical (criteria(Hist)) and IWG (criteria(IWG)) ITP criteria to available clinical data. Results. Among the 505 patients seen for ITP over 7 years, 98% could be classified as "acute" or "chronic" ITP using the criteriaHist, while only 90.7% could be classified as "newly diagnosed," "persistent," or "chronic" ITP using the criteriaIWG (P < 0.01). Only 33.7% met criteriaIWG for severe ITP, whereas 77.4% met criteriaHist for severe ITP. A striking difference was that overall response to therapies was lower if the criteriaIWG were used rather than the criteriaHist, particularly for IVIG (55.4% vs. 70%, P = 0.02) and rituximab (35.3% vs. 83.3% P = 0.05). Only 2 subjects (0.4%) met the criteriaIWG for refractory ITP. Conclusions. Most ITP patients could easily be classified using the 2009 criteriaIWG. Limitations to applying the criteriaIWG included absence of treatment response durations, incomplete definition of pediatric "refractory ITP," and exclusion of secondary ITP. Nevertheless, the criteriaIWG were more clinically relevant given the reliance on definitions based on bleeding and their ability to be applied prospectively. The utility of using the criteriaIWG within prospective trials remains to be determined. Pediatr Blood Cancer 2012; 58: 216-220. (C) 2011 Wiley Periodicals, Inc.

AB Background Treatment choice in pediatric immune thrombocytopenia (ITP) is arbitrary, because few studies are powered to identify predictors of therapy response. Increasingly, rituximab is becoming a treatment of choice in those refractory to other therapies. Methods. The objective of this study was to evaluate univariate and multivariable predictors of platelet count response to rituximab. After local IRB approval, 565 patients with chronic ITP enrolled and met criteria for this study in the longitudinal, North American Chronic ITP Registry (NACIR) between January 2004 and October 2010. Treatment response was defined as a post-treatment platelet count >= 50,000/mu l within 16 weeks of rituximab and 14 days of steroids. Treatment response data were captured both retrospectively at enrollment and then prospectively. Results. Eighty (14.2%) patients were treated with rituximab with an overall response rate of 63.8% (51/ 80). Univariate correlates of response to rituximab included the presence of secondary ITP and a positive response to steroids. In multivariable analysis, response to steroids remained a strong correlate of response to rituximab, OR 6.8 (95% CI 2.0-23.0, P = 0.002). Secondary ITP also remained a strong predictor of response to rituximab, OR 5.6 (95% CI 1.1-28.6, P = 0.04). Although 87.5% of patients who responded to steroids responded to rituximab, 48% with a negative response to steroids did respond to rituximab. Conclusion. In the NACIR, response to steroids and presence of secondary ITP were strong correlates of response to rituximab, a finding not previously reported in children or adults.

AB Background Hematopoietic stem cell transplantation (HSCT) can be challenging to pediatric recipients and their families. Little is known about the recipients' psychological status as they initiate treatment and in the year afterwards. The purpose of this study is to describe the psychological status of 107 pediatric HSCT recipients from their parents' perspective, and to compare reports from parents and children in a subset of 55 children. We hypothesized that there would be discrepancies between parent and child report of child distress. Procedure. Multi-site, prospective study of eligible child participants and their parents who completed selected modules from the Structured Clinical Interview for DSM-IV-TR, Childhood Version (KID-SCID) the month before and one year after HSCT. Diagnoses were threshold or subthreshold. Results. According to parents, nearly 30% of children had anxiety disorder both before and after HSCT; approximately half of these met threshold criteria. Agreement between parents and children for anxiety disorders was poor at baseline (kappa = 0.18, 95% CI = -0.33, -0.02) and fair at 12 months (kappa = 0.31, 95% CI = -0.04, 0.66). Agreement about mood disorders was fair at baseline (10% prevalence, kappa = 0.39, 95% CI = -0.02, 0.79) and moderate at 12 months (14% prevalence, kappa = 0.41, 95% CI 0.02, 0.80). Conclusions. Anxiety (30%) and mood (10-14%) symptoms are common in children both before and after HSCT; parent and child reports of these symptoms do not agree. Input from parents and children is recommended to identify more accurately children who may need additional intervention during and following HSCT Pediatr Blood Cancer 2012; 58: 289-296.

AB To determine the incidence of inadvertent lumbar facet joint injection during an interlaminar epidural steroid injection (ESI).
A total of 686 interlaminar lumbar ESIs were performed from January 1, 2009 to December 31, 2009. Archived images from these cases were retrospectively reviewed on the PACS. Positive cases of inadvertent lumbar facet joint injection were identified by the characteristic sigmoid-shaped contrast pattern projecting over the posterior elements on the lateral view and/or ovoid contrast projecting over the facet joints on the anteroposterior (AP) view.
Eight positive events were identified (1.2%). There was no statistically significant gender or lumbar level predilection. In 3/8 of the positive cases (37.5%), the inadvertent facet joint injection was recognized by the operator. The needle was repositioned as a result, and contrast within the posterior epidural space was documented by the end of the procedure. In 5/8 of the positive cases (62.5%), the patients reported an immediate decrease in the presenting pain.
The incidence of inadvertent lumbar facet joint injection during an interlaminar epidural steroid injection is low. Recognizing the imaging features of this event permits the operator to redirect the needle tip into the epidural space and/or identify the facet joint(s) as a source of the patient's presenting pain.

AB OBJECTIVE: We sought to define the prevalence, trends, and outcomes of primary and secondary chronic hypertension in a population-based sample of deliveries.
STUDY DESIGN: An estimated 56,494,634 deliveries were identified from the 1995 through 2008 Nationwide Inpatient Sample. The association of primary and secondary chronic hypertension with adverse fetal and maternal outcomes was evaluated using regression modeling and adjusted population-attributable fractions were calculated.
RESULTS: During the study period, the prevalence of primary and secondary hypertension increased from 0.90% in 1995 through 1996 to 1.52% in 2007 through 2008 (P for trend <.001) and from 0.07% to 0.24% (P for trend <.001), respectively. The population-attributable fraction for chronic hypertension was considerable for many maternal adverse outcomes, including acute renal failure (21%), pulmonary edema (14%), preeclampsia (11%), and in-hospital mortality (10%).
CONCLUSION: Primary and secondary chronic hypertension were both strongly associated with adverse pregnancy outcomes and accounted for a substantial fraction of maternal morbidity. Prioritizing research efforts in this area is needed.

TI Antithrombotic Therapy for Atrial Fibrillation Antithrombotic Therapy
and Prevention of Thrombosis, 9th ed: American College of Chest
Physicians Evidence-Based Clinical Practice Guidelines
SO CHEST
LA English
DT Article
AB Background: The risk of stroke varies considerably across different groups of patients with atrial fibrillation (AF). Antithrombotic prophylaxis for stroke is associated with an increased risk of bleeding. We provide recommendations for antithrombotic treatment based on net clinical benefit for patients with AF at varying levels of stroke risk and in a number of common clinical scenarios.
Methods: We used the methods described in the Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines article of this supplement.
Results: For patients with nonrheumatic AF, including those with paroxysmal AF, who are (1) at low risk of stroke (eg, CHADS(2) [congestive heart failure, hypertension, age >= 75 years, diabetes mellitus, prior stroke or transient ischemic attack] score of 0), we suggest no therapy rather than antithrombotic therapy, and for patients choosing antithrombotic therapy, we suggest aspirin rather than oral anticoagulation or combination therapy with aspirin and clopidogrel; (2) at intermediate risk of stroke (eg, CHADS(2) score of 1), we recommend oral anticoagulation rather than no therapy, and we suggest oral anticoagulation rather than aspirin or combination therapy with aspirin and clopidogrel; and (3) at high risk of stroke (eg, CHADS(2) score of >= 2), we recommend oral anticoagulation rather than no therapy, aspirin, or combination therapy with aspirin and clopidogrel. Where we recommend or suggest in favor of oral anticoagulation, we suggest dabigatran 150 mg bid rather than adjusted-dose vitamin K antagonist therapy.
Conclusions: Oral anticoagulation is the optimal choice of antithrombotic therapy for patients with AF at high risk of stroke (CHADS(2) score of >= 2). At lower levels of stroke risk, antithrombotic treatment decisions will require a more individualized approach.

TI Competing Influences in the Management of Gastrointestinal Bleeding
SO CLINICAL AND TRANSLATIONAL GASTROENTEROLOGY
LA English
DT Article
AB OBJECTIVES: Management of gastrointestinal (GI) bleeding centers on the issues of location, type of mucosal lesion, effects of anticoagulation, diagnosis, and therapy. Each one of these five individual factors is affected by multiple interactions with the other coexisting factors. The aim of the present study is to analyze which set of factors ultimately exerts the largest and most lasting influence on the disease process.
METHODS: The interactions among the five contributing factors are analyzed using a transposed Markov chain model.
RESULTS: The analysis reveals that, in declining order, location, anticoagulation, and type of lesion exert the largest influence on the disease process. Under steady state conditions, their magnitudes of influence are 50, 33, and 17%, respectively. The other two factors, diagnosis and therapy, result as a consequence of the aforementioned three primary factors, but do not exert any major influence themselves. The outcome of the analysis remains robust to multiple wide-ranging variations in the assumptions underlying the model.
CONCLUSIONS: The model of a transposed Markov chain translates an initially bewildering array of interacting influences into a coherent and transparent model of gastrointestinal bleeding.

TI Age-Related Patterns in Clinical Presentations and Gluten-Related Issues
Among Children and Adolescents With Celiac Disease
SO CLINICAL AND TRANSLATIONAL GASTROENTEROLOGY
LA English
DT Article
AB OBJECTIVES: Celiac disease (CD) is common and often cited as an "iceberg'' phenomenon (i.e., an assumed large number of undiagnosed cases). Recently, atypical or asymptomatic manifestations are becoming more commonly described in older children and adolescents. Moreover, CD diagnosis in children can be complicated by several factors, including its diverse clinical presentations, delay in recognizing CD signs and symptoms, and premature dietary gluten avoidance before the formal diagnosis of CD. To date, few studies have directly examined age-related differences in clinical characteristics and gluten-related issues among children with CD. The aim of this study was to determine age-related patterns in clinical characteristics and gluten-related issues among children with confirmed CD.
METHODS: We performed a structured medical record review of biopsy-proven CD patients, aged 0-19 years, between 2000 and 2010 at a large Boston teaching hospital. Data collection included demographics, medical history, gluten-related issues, and diagnostic investigations (CD-specific serology, upper gastrointestinal endoscopy, and small intestinal biopsy). The first positive duodenal biopsy with Marsh III classification defined age of diagnosis. Patients were divided into three age groups for comparisons of the aforementioned characteristics: infant-preschool group (0-5 years), school-aged group (6-11 years), and adolescence group (12-19 years).
RESULTS: Among 411 children with biopsy-proven CD, the mean age was 9.5 (s.d. 5.1) years. Most were female (63%) and white (96%). All children had positive CD-specific serology. Most children presented with either abdominal complaints or bowel movement changes. Overall, boys were more common among infant-preschool group compared with the other age groups. More distinct clinical manifestations (vomiting, bowel movement changes, and weight issues) were apparent in the youngest group, whereas school-aged children had more subjective abdominal complaints at the initial presentation. Conversely, the adolescents were most likely to present without any gastrointestinal (GI) symptoms, but not when this was combined with absence of weight issues. Age of diagnosis was not associated with atypical extraintestinal CD presentations. Regarding the gluten-related issues, 10% of school-aged children avoided dietary gluten before the formal CD diagnosis, and 27% of the adolescents reported dietary gluten transgression within the first 12 months of diagnosis, significantly higher than the other age groups. Age differences in histopathology were also found. Whereas the infant-preschool group had a higher proportion of total villous atrophy, the older children were more likely to have gross duodenal abnormalities and chronic duodenitis suggestive of CD at the time of diagnosis.
CONCLUSIONS: Children and adolescents with CD have age-related patterns in both the clinical presentations and gluten-related issues. More pronounced clinical and histological features were determined in younger children, whereas older children more commonly presented with solely subjective abdominal complaints or even without any GI symptoms. However, silent and atypical extraintestinal CD presentations were comparable between age groups. In addition to the aforementioned presentations, the higher rates of dietary gluten avoidance and transgression in older children make CD diagnosis and management particularly challenging. These age-related patterns may further increase awareness, facilitate early diagnosis, and improve patient care of pediatric CD.

AB Cholera is an acute, severe diarrheal disease caused by Vibrio cholerae that affects millions of people each year. Without prompt rehydration, death can occur within hours of the onset of symptoms. In October 2010, cholera emerged in Haiti, and the resulting large epidemic continues today. As of August 29, 2011, more than 439,000 cases have been reported in Haiti, with over 6,200 deaths. This review covers important features of epidemiology, pathogenesis, treatment and prevention of cholera, with a focus on the ongoing epidemic in Haiti.

AB The clinical issues affecting women with HIV/AIDS differ little from those affecting men. However, current research shows that treatment and outcome disparities affect many women with HIV, hypothesized to result from a complex interplay of socioeconomic and gender role influences. These disparities are also a reflection of racial/ethnic differences in treatment and outcome, since 80% of women with HIV/AIDS are black or Hispanic. Women have unique needs for HIV prevention - both prevention of sexual transmission to or from sexual partners and prevention of perinatal transmission. Racial/ethnic minorities continue to be disproportionately affected by the HIV/AIDS epidemic in the U. S. Minorities are less likely to be in care and on HAART than others with HIV/AIDS. These disparities result in poorer outcomes for minorities, especially blacks, with HIV/AIDS. New strategies for optimizing engagement and retention in care, and for prevention hold great promise for women and minorities with HIV in the U.S.

AB Background-In randomized controlled trials (RCTs) of subjects with type 2 diabetes mellitus, mortality rates vary substantially. We sought to examine the inclusion and exclusion criteria of these RCTs to explore relationships with mortality.
Methods and Results-MEDLINE database was searched from August 1980 through March 2011. Selection criterion included published RCTs of adults with type 2 diabetes mellitus of at least 1000 patients, reporting all-cause mortality and having follow-up duration of at least 1 year. Twenty-two trials were eligible. Annualized mortality rates were derived. Inclusion and exclusion criteria were tabulated for each trial. Trials were categorized in 4 groups according to annual mortality rates: <1, >= 1 to <2, >= 2 to <4, and >= 4 per 100 patient-years. The analysis cohort included 91842 patients and 6837 deaths. Mortality rates ranged from 0.28 to 8.24 per 100 patient-years. Patients enrolled in the highest mortality category were more likely to be older and had longer diabetes duration and higher blood pressure. The selection for hypertension was common in the low-as well as high-mortality trials. Although the mortality rates were higher in RCTs with prior cardiovascular morbidity, the selection for chronic kidney disease-defined by either higher serum creatinine or lower estimated glomerular filtration rate and/or the presence of proteinuria-was associated with the highest mortality rates.
Conclusions-In this analysis of RCTs of type 2 diabetes mellitus, a 29-fold difference in annualized mortality was observed. In these RCTs, selection for renal disease, defined by either decline in renal function or presence of proteinuria, portends important mortality risk.

AB Background-The National Institutes of Health Stroke Scale (NIHSS), a well-validated tool for assessing initial stroke severity, has previously been shown to be associated with mortality in acute ischemic stroke. However, the relationship, optimal categorization, and risk discrimination with the NIHSS for predicting 30-day mortality among Medicare beneficiaries with acute ischemic stroke has not been well studied.
Methods and Results-We analyzed data from 33102 fee-for-service Medicare beneficiaries treated at 404 Get With The Guidelines-Stroke hospitals between April 2003 and December 2006 with NIHSS documented. The 30-day mortality rate by NIHSS as a continuous variable and by risk-tree determined or prespecified categories were analyzed, with discrimination of risk quantified by the c-statistic. In this cohort, mean age was 79.0 years and 58% were female. The median NIHSS score was 5 (25th to 75th percentile 2 to 12). There were 4496 deaths in the first 30 days (13.6%). There was a strong graded relation between increasing NIHSS score and higher 30-day mortality. The 30-day mortality rates for acute ischemic stroke by NIHSS categories were as follows: 0 to 7, 4.2%; 8 to 13, 13.9%; 14 to 21, 31.6%; 22 to 42, 53.5%. A model with NIHSS alone provided excellent discrimination whether included as a continuous variable (c-statistic 0.82 [0.81 to 0.83]), 4 categories (c-statistic 0.80 [0.79 to 0.80]), or 3 categories (c-statistic 0.79 [0.78 to 0.79]).
Conclusions-The NIHSS provides substantial prognostic information regarding 30-day mortality risk in Medicare beneficiaries with acute ischemic stroke. This index of stroke severity is a very strong discriminator of mortality risk, even in the absence of other clinical information, whether used as a continuous or categorical risk determinant.

TI miR-1289 and "Zipcode"-like Sequence Enrich mRNAs in Microvesicles
SO MOLECULAR THERAPY-NUCLEIC ACIDS
LA English
DT Article
AB Despite intensive studies, the molecular mechanisms by which the genetic materials are uploaded into microvesicles (MVs) are still unknown. This is the first study describing a zipcode-like 25 nucleotide (nt) sequence in the 3'-untranslated region (3'UTR) of mRNAs, with variants of this sequence present in many mRNAs enriched in MVs, as compared to their glioblastoma cells of origin. When this sequence was incorporated into the 3' UTR of a reporter message and expressed in a different cell type, it led to enrichment of the reporter mRNA in MVs. Critical features of this sequence are both a CUGCC core presented on a stemloop structure and a miRNA-binding site, with increased levels of the corresponding miRNA in cells further increasing levels of mRNAs in MVs.

AB The reconstruction, repair, and regeneration of the external auricular framework continue to be one of the greatest challenges in the field of tissue engineering. To replace like with like, we should emulate the native structure and composition of auricular cartilage by combining a suitable chondrogenic cell source with an appropriate scaffold under optimal in vitro and in vivo conditions. Due to the fact that a suitable and reliable substitute for auricular cartilage has yet to be engineered, hand-carved autologous costal cartilage grafts and ear-shaped porous polyethylene implants are the current treatment modalities for auricular reconstruction. However, over the last decade, significant advances have been made in the field of regenerative medicine and tissue engineering. A variety of scaffolds and innovative approaches have been investigated as alternatives to using autologous carved costal cartilage or porous polyethylene implants. A review of recent developments and the current state of the art and science is presented, focusing on scaffolds, cell sources, seeding densities, and mechanical characteristics of tissue-engineered auricular cartilage.

AB Information routing is one of the most important problems in large communication networks. In this paper we propose a novel routing strategy in which the optimal paths between all pairs of nodes are chosen according to a cost function that incorporates degrees of nodes in paths. Results on large scale-free networks demonstrate that our routing strategy is more efficient than the shortest path algorithm and the efficient routing strategy proposed by Van et al. [Phys. Rev. E 73, 046108 (2006)]. Furthermore our routing strategy has strong robustness against cascading failure attacks on networks. (C) 2011 Elsevier B.V. All rights reserved.

AB The presence of metaplastic ossification within atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS) is a rare occurrence. When present, bone formation is most often found in association with a dedifferentiated component arising within the primary tumor. It is important for the radiologist not only to recognize the differential diagnosis of a calcified or ossified soft tissue mass but also be aware of the various soft tissue neoplasms, both aggressive and non-aggressive, that may show such features. We report a case of ALT/WDLPS with unusual extensive metaplastic bone formation without an element of dedifferentiated liposarcoma.

AB The gamma-aminobutyric acid type A receptor (GABAAR) is a target for general anesthetics of diverse chemical structures, which act as positive allosteric modulators at clinical doses. Previously, in a heterogeneous mixture of GABA(A)Rs purified from bovine brain, [H-3]azietomidate photolabeling of alpha Met-236 and beta Met-286 in the alpha M1 and beta M3 transmembrane helices identified an etomidate binding site in the GABA(A)R transmembrane domain at the interface between the beta and alpha subunits [Li, G. D., et.al. (2006) J. Neurosci. 26, 11599-11605]. To further define GABAAR etomidate binding sites, we now use [H-3]TDBzl-etomidate, an aryl diazirine with broader amino acid side chain reactivity than azietornidate, to photolabel purified human FLAG-alpha 1 beta 3 GABA(A)Rs and more extensively identify photolabeled GABA(A)R amino acids. PHYTDBzl-etomidate photolabeled in an etomidate-inhibitable manner beta 3Val-290, in the beta 3M3 transmembrane helix, as well as alpha 1Met-236 in alpha 1M1, a residue photolabeled by [H-3]azietomidate, while no photolabeling of amino acids in the alpha M2 and beta M2 helices that also border the etornidate binding site was detected. The location of these photolabeled amino acids in GABA(A)R homology models derived from the recently determined structures of prokaryote (GLIC) or invertebrate (GluCl) homologues and the results of computational docking studies predict the orientation of [H-3]TDBzl-etomidate bound in that site and the other amino acids contributing to this GABA(A)R intersubunit etomidate binding site. Etomidate-inhibitable photolabeling of beta Met-227 in beta M1 by [H-3]TDBzl-etomidate and [H-3]azietomidate also provides evidence of a homologous etomidate binding site at the beta 3-beta 3 subunit interface in the alpha 1 beta 3 GABA(A)R.

AB Background-The availability of more sensitive biomarkers of myonecrosis and a new classification system from the universal definition of myocardial infarction (MI) have led to evolution of the classification of MI. The prognostic implications of MI defined in the current era have not been well described.
Methods and Results-We investigated the association between new or recurrent MI by subtype according to the European Society of Cardiology/American College of Cardiology/American Heart Association/World Health Federation Task Force for the Redefinition of MI Classification System and the risk of cardiovascular death among 13 608 patients with acute coronary syndrome in the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition with Prasugrel-Thrombolysis in Myocardial Infarction 38 (TRITON-TIMI 38). The adjusted risk of cardiovascular death was evaluated by landmark analysis starting at the time of the MI through 180 days after the event. Patients who experienced an MI during follow-up had a higher risk of cardiovascular death at 6 months than patients without an MI (6.5% versus 1.3%, P<0.001). This higher risk was present across all subtypes of MI, including type 4a (peri-percutaneous coronary intervention, 3.2%; P<0.001) and type 4b (stent thrombosis, 15.4%; P<0.001). After adjustment for important clinical covariates, the occurrence of any MI was associated with a 5-fold higher risk of death at 6 months (95% confidence interval 3.8-7.1), with similarly increased risk across subtypes.
Conclusions-MI is associated with a significantly increased risk of cardiovascular death, with a consistent relationship across all types as defined by the universal classification system. These findings underscore the clinical relevance of these events and the importance of therapies aimed at preventing MI.

AB Objectives This study examined short-term cardiac catheterization rates and medication changes after cardiac imaging.
Background Noninvasive cardiac imaging is widely used in coronary artery disease, but its effects on subsequent patient management are unclear.
Methods We assessed the 90-day post-test rates of catheterization and medication changes in a prospective registry of 1,703 patients without a documented history of coronary artery disease and an intermediate to high likelihood of coronary artery disease undergoing cardiac single-photon emission computed tomography, positron emission tomography, or 64-slice coronary computed tomography angiography.
Results Baseline medication use was relatively infrequent. At 90 days, 9.6% of patients underwent catheterization. The rates of catheterization and medication changes increased in proportion to test abnormality findings. Among patients with the most severe test result findings, 38% to 61% were not referred to catheterization, 20% to 30% were not receiving aspirin, 35% to 44% were not receiving a beta-blocker, and 20% to 25% were not receiving a lipid-lowering agent at 90 days after the index test. Risk-adjusted analyses revealed that compared with stress single-photon emission computed tomography or positron emission tomography, changes in aspirin and lipid-lowering agent use was greater after computed tomography angiography, as was the 90-day catheterization referral rate in the setting of normal/nonobstructive and mildly abnormal test results.
Conclusions Overall, noninvasive testing had only a modest impact on clinical management of patients referred for clinical testing. Although post-imaging use of cardiac catheterization and medical therapy increased in proportion to the degree of abnormality findings, the frequency of catheterization and medication change suggests possible undertreatment of higher risk patients. Patients were more likely to undergo cardiac catheterization after computed tomography angiography than after single-photon emission computed tomography or positron emission tomography after normal/nonobstructive and mildly abnormal study findings.

AB Objective To examine the association between chronic use of proton pump inhibitors (PPIs) and risk of hip fracture.
Design Prospective cohort study.
Setting Nurses' Health Study, which originally recruited from the 11 most populous states in the US.
Participants 79 899 postmenopausal women enrolled in the Nurses' Health Study who provided data on the use of PPIs and other risk factors biennially since 2000 and were followed up to 1 June 2008.
Main outcome measure Incident hip fracture
Results During 565 786 person years of follow-up, we documented 893 incident hip fractures. The absolute risk of hip fracture among regular users of PPIs was 2.02 events per 1000 person years, compared with 1.51 events per 1000 person years among non-users. Compared with non-users, the risk of hip fracture among women who regularly used PPIs for at least two years was 35% higher (age adjusted hazard ratio 1.35 (95% confidence interval 1.13 to 1.62)), with longer use associated with increasing risk (P-trend<0.01). Adjustment for risk factors, including body mass index, physical activity, and intake of calcium did not materially alter this association (hazard ratio 1.36 (1.13 to 1.63)). These associations were also not changed after accounting for reasons for PPI use. The relation between PPI use and fracture differed by smoking history (P-interaction=0.03). Among current and former smokers, PPI use was associated with greater than 50% increase in risk of fracture, with a multivariate hazard ratio for fracture of 1.51 (1.20 to 1.91). In contrast, among women who never smoked there was no association (multivariate hazard ratio 1.06 (0.77 to 1.46)). In a meta-analysis of these results with 10 prior studies, the pooled odds ratio of hip fracture associated with PPI use was 1.30 (1.25 to 1.36).
Conclusion Chronic use of PPIs is associated with increased risk of hip fracture, particularly among women with a history of smoking.

AB Ischemia of the myocardium and lower limbs is a common consequence of arterial disease and a major source of morbidity and mortality in modernized countries. Inducing neovascularization for the treatment of ischemia is an appealing therapeutic strategy for patients for whom traditional treatment modalities cannot be performed or are ineffective. In the past, the stimulation of blood vessel growth was pursued using direct delivery of growth factors, angiogenic gene therapy, or cellular therapy. Although therapeutic angiogenesis holds great promise for treating patients with ischemia, current methods have not found success in clinical trials. Fibroblast growth factor-2 (FGF-2) was one of the first growth factors to be tested for use in therapeutic angiogenesis. Here, we present a method for improving the biological activity of FGF-2 by codelivering the growth factor with a liposomally embedded coreceptor, syndecan-4. This technique was shown to increase FGF-2 cellular signaling, uptake, and nuclear localization in comparison with FGF-2 alone. Delivery of syndecan-4 proteoliposomes also increased endothelial proliferation, migration, and angiogenic tube formation in response to FGF-2. Using an animal model of limb ischemia, syndecan-4 proteoliposomes markedly improved the neovascularization following femoral artery ligation and recovery of perfusion of the ischemic limb. Taken together, these results support liposomal delivery of syndecan-4 as an effective means to improving the potential of using growth factors to achieve therapeutic neovascularization of ischemic tissue.

AB Intracranial recording is an important diagnostic method routinely used in a number of neurological monitoring scenarios. In recent years, advancements in such recordings have been extended to include unit activity of an ensemble of neurons. However, a detailed functional characterization of excitatory and inhibitory cells has not been attempted in human neocortex, particularly during the sleep state. Here, we report that such feature discrimination is possible from high-density recordings in the neocortex by using 2D multielectrode arrays. Successful separation of regular-spiking neurons (or bursting cells) from fast-spiking cells resulted in well-defined clusters that each showed unique intrinsic firing properties. The high density of the array, which allowed recording from a large number of cells (up to 90), helped us to identify apparent monosynaptic connections, confirming the excitatory and inhibitory nature of regular-spiking and fast-spiking cells, thus categorized as putative pyramidal cells and interneurons, respectively. Finally, we investigated the dynamics of correlations within each class. A marked exponential decay with distance was observed in the case of excitatory but not for inhibitory cells. Although the amplitude of that decline depended on the time-scale at which the correlations were computed, the spatial constant did not. Furthermore, this spatial constant is compatible with the typical size of human columnar organization. These findings provide a detailed characterization of neuronal activity, functional connectivity at the microcircuit level, and the interplay of excitation and inhibition in the human neocortex.

AB Background: HIV-1 infection is associated with profound dysfunction of myeloid dendritic cells, for reasons that remain ill-defined. Soluble HLA class I molecules can have important inhibitory effects on T cells and NK cells, but may also contribute to reduced functional properties of professional antigen-presenting cells. Here, we investigated the expression of soluble HLA class I isoforms during HIV-1 infection and assessed their functional impact on antigen-presenting characteristics of dendritic cells.
Results: Soluble HLA class I molecules were highly upregulated in progressive HIV-1 infection as determined by quantitative Western blots. This was associated with strong increases of intracellular expression of HLA class I isoforms in dendritic cells and monocytes. Using mixed lymphocyte reactions, we found that soluble HLA class I molecules effectively inhibited the antigen-presenting properties of dendritic cells, however, there was no significant influence of HLA class I molecules on the cytokine-secretion properties of these cells. The immunomodulatory effects of soluble HLA class I molecules were mediated by interactions with inhibitory myelomonocytic MHC class I receptors from the Leukocyte Immunoglobulin Like Receptor (LILR) family.
Conclusions: During progressive HIV-1 infection, soluble HLA class I molecules can contribute to systemic immune dysfunction by inhibiting the antigen-presenting properties of myeloid dendritic cells through interactions with inhibitory myelomonocytic HLA class I receptors.

AB In vivo optical microscopic imaging techniques have recently emerged as important tools for the study of neurobiological development and pathophysiology. In particular, two-photon microscopy has proved to be a robust and highly flexible method for in vivo imaging in highly scattering tissue. However, two-photon imaging typically requires extrinsic dyes or contrast agents, and imaging depths are limited to a few hundred microns. Here we demonstrate Optical Coherence Microscopy (OCM) for in vivo imaging of neuronal cell bodies and cortical myelination up to depths of similar to 1.3 mm in the rat neocortex. Imaging does not require the administration of exogenous dyes or contrast agents, and is achieved through intrinsic scattering contrast and image processing alone. Furthermore, using OCM we demonstrate in vivo, quantitative measurements of optical properties (index of refraction and attenuation coefficient) in the cortex, and correlate these properties with laminar cellular architecture determined from the images. Lastly, we show that OCM enables direct visualization of cellular changes during cell depolarization and may therefore provide novel optical markers of cell viability.

AB Cryoglobulins are immunoglobulins that precipitate in vitro at temperatures less than 37 degrees C and produce organ damage through two main pathways: vascular sludging (hyperviscosity syndrome, mainly in type I cryoglobulinaemia) and immune-mediated mechanisms (principally vasculitis, in mixed cryoglobulinaemia). Cryoglobulinaemia is associated with many illnesses, which can be broadly grouped into infections, autoimmune disorders, and malignancies; the most common cause is infection with hepatitis C virus. Mixed cryoglobulinaemic syndrome is diagnosed when a patient has typical organ involvement (mainly skin, kidney, or peripheral nerve) and circulating cryoglobulins. Cutaneous purpura is the most common manifestation of cryoglobulinaemic vasculitis. The most frequently affected internal organs are the peripheral nerves, kidneys, and joints. The course varies widely and prognosis is influenced by both cryoglobulinaemic damage to vital organs and by comorbidities associated with underlying diseases. More than 90% of cases of cryoglobulinaemia have a known underlying cause; therefore treatment is focused on the cause of the disorder rather than merely symptomatic relief. Studies suggest that both combined or sequential antiviral therapies and targeted biological treatments might be more effective than monotherapy.

TI Nox4 Mediates Renal Cell Carcinoma Cell Invasion through Hypoxia-Induced
Interleukin 6-and 8-Production
SO PLOS ONE

DT Article

FACTOR-I; ENDOTHELIAL-CELLS; OXIDATIVE STRESS; NAD(P)H OXIDASE;
ACTIVATION; EXPRESSION; INFLAMMATION
AB Background: Inflammatory cytokines are detected in the plasma of patients with renal cell carcinoma (RCC) and are associated with poor prognosis. However, the primary cell type involved in producing inflammatory cytokines and the biological significance in RCC remain unknown. Inflammation is associated with oxidative stress, upregulation of hypoxia inducible factor 1-alpha, and production of pro-inflammatory gene products. Solid tumors are often heterogeneous in oxygen tension together suggesting that hypoxia may play a role in inflammatory processes in RCC. Epithelial cells have been implicated in cytokine release, although the stimuli to release and molecular mechanisms by which they are released remain unclear. AMP-activated protein kinase (AMPK) is a highly conserved sensor of cellular energy status and a role for AMPK in the regulation of cell inflammatory processes has recently been demonstrated.
Methods and Principal Findings: We have identified for the first time that interleukin-6 and interleukin-8 (IL-6 and IL-8) are secreted solely from RCC cells exposed to hypoxia. Furthermore, we demonstrate that the NADPH oxidase isoform, Nox4, play a key role in hypoxia-induced IL-6 and IL-8 production in RCC. Finally, we have characterized that enhanced levels of IL-6 and IL-8 result in RCC cell invasion and that activation of AMPK reduces Nox4 expression, IL-6 and IL-8 production, and RCC cell invasion.
Conclusions/Significance: Together, our data identify novel mechanisms by which AMPK and Nox4 may be linked to inflammation-induced RCC metastasis and that pharmacological activation of AMPK and/or antioxidants targeting Nox4 may represent a relevant therapeutic intervention to reduce IL-6- and IL-8-induced inflammation and cell invasion in RCC.

TI Grape Seed Proanthocyanidins Inhibit the Invasiveness of Human HNSCC

AB Head and neck squamous cell carcinoma (HNSCC) is responsible for approximately 20,000 deaths per year in the United States. Most of the deaths are due to the metastases. To develop more effective strategies for the prevention of metastasis of HNSCC cells, we have determined the effect of grape seed proanthocyanidins (GSPs) on the invasive potential of HNSCC cell and the mechanisms underlying these effects using OSC19 cells as an in vitro model. Using cell invasion assays, we established that treatment of the OSC19 cells with GSPs resulted in a dose-dependent inhibition of cell invasion. EGFR is over-expressed in 90% of HNSCCs and the EGFR inhibitors, erlotinib and gefitinib, are being explored as therapies for this disease. We found that GSPs treatment reduced the levels of expression of EGFR in the OSC19 cells as well as reducing the activation of NF-kappa B/p65, a downstream target of EGFR, and the expression of NF-kappa B-responsive proteins. GSPs treatment also reduced the activity of ERK1/2, an upstream regulator of NF-kappa B and treatment of the cells with caffeic acid phenethyl ester, an inhibitor of NF-kappa B, inhibited cell invasion. Overexpression of EGFR and high NF-kappa B activity play a key role in the epithelial-to-mesenchymal transition, which is of critical importance in the processes underlying metastasis, and we found treatment with GSPs enhanced the levels of epithelial (E-cadherin, cytokeratins and desmoglein-2) and reduced the levels of mesenchymal (vimentin, fibronectin, N-cadherin and Slug) biomarkers in the OSC19 cells. These results indicate that GSPs have the ability to inhibit HNSCC cell invasion, and do so by targeting the expression of EGFR and activation of NF-kappa B as well as inhibiting the epithelial-to-mesenchymal transition.

AB Activation of p38 MAPK is a key pathway for cell proliferation and differentiation in breast cancer and thyroid cells. The sodium/iodide symporter (NIS) concentrates iodide in the thyroid and lactating breast. All-trans-retinoic acid (tRA) markedly induces NIS activity in some breast cancer cell lines and promotes uptake of beta-emitting radioiodide I-131 sufficient for targeted cytotoxicity. To identify a signal transduction pathway that selectively stimulates NIS expression, we investigated regulation by the Rac1-p38 signaling pathway in MCF-7 breast cancer cells and compared it with regulation in FRTL-5 rat thyroid cells. Loss of function experiments with pharmacologic inhibitors and small interfering RNA, as well as RT-PCR analysis of p38 isoforms, demonstrated the requirement of Rac1, MAPK kinase 3B, and p38 beta for the full expression of NIS in MCF-7 cells. In contrast, p38 alpha was critical for NIS expression in FRTL-5 cells. Treatment with tRA or overexpression of Rac1 induced the phosphorylation of p38 isoforms, including p38 beta. A dominant negative mutant of Rac1 abolished tRA-induced phosphorylation in MCF-7 cells. Overexpression of p38 beta or Rac1 significantly enhanced (1.9- and 3.9-fold, respectively), the tRA-stimulated NIS expression in MCF-7 cells. This study demonstrates differential regulation of NIS by distinct p38 isoforms in breast cancer cells and thyroid cells. Targeting isoform-selective activation of p38 may enhance NIS induction, resulting in higher efficacy of I-131 concentration and treatment of breast cancer.

TI Protein misfolding, mitochondrial dysfunction and muscle loss are not

AB Mutant superoxide dismutase 1 (mSOD1) is often found as aggregates at the outer-membrane of mitochondria in motor neurons of various mouse models and familial amyotrophic lateral sclerosis (f-ALS) patients. It has been postulated that disruption of mitochondrial function by physical association of misfolded mSOD1 aggregates may actually be the trigger for initiation of degeneration of motor neurons in ALS. However, it was not clear if the same mechanism is involved in muscle degeneration and mitochondrial dysfunction in skeletal muscles of ALS. Recent study from our laboratory show that two skeletal muscle proteins, namely creatine kinase (CK) and glyceraldehydes-3-phosphate dehydrogenase (GAPDH) undergo major conformational and functional changes in the f-ALS mouse model of ALS (G93A). In this paper, we report two intriguing observations which are as follows:(i) G93A protein does not form aggregates in skeletal muscle at any stages of disease process probably due to high chymotrypsin-like activity of proteasome and thus G93A protein aggregates have no direct effects on progressive loss of muscle mass and global changes in protein conformation in ALS, and (ii) the soluble G93A protein does not have direct effects on mitochondrial dysfunction as determined by quantifying the release of reactive oxygen species (ROS) in skeletal muscle mitochondria; instead, the proteins affected by G93A possibly affect mitochondrial ROS release. These data strongly suggest for the first time that unlike in motor neurons, the soluble and aggregation states of the G93A protein do not have direct effects on protein misfolding and mitochondrial dysfunction in skeletal muscle during ALS.

AB The mitogen-activated kinases JNK1/2/3 are key enzymes in signaling modules that transduce and integrate extracellular stimuli into coordinated cellular response. Here, we report the discovery of irreversible inhibitors of JNK1/2/3. We describe two JNK3 cocrystal structures at 2.60 and 2.97 angstrom resolution that show the compounds form covalent bonds with a conserved cysteine residue. JNK-IN-8 is a selective JNK inhibitor that inhibits phosphorylation of c-Jun, a direct substrate of JNK, in cells exposed to submicromolar drug in a manner that depends on covalent modification of the conserved cysteine residue. Extensive biochemical, cellular, and pathway-based profiling establish the selectivity of JNK-IN-8 for JNK and suggests that the compound will be broadly useful as a pharmacological probe of JNK-dependent signal transduction. Potential lead compounds have also been identified for kinases, including IRAK1, PIK3C3, PIP4K2C, and PIP5K3.

AB Background. Although 12 days of high dose of FK506 permits the induction of tolerance of fully major histocompatibility complex (MHC)-mismatched allogeneic kidneys in MGH-miniature swine, we found that the same dose of FK506 is insufficient to induce such tolerance CLAWN-miniature swine. The CLAWN swine model was therefore chosen to study the potential immunoregulatory effects of human-recombinant hepatocyte growth factor (HGF).
Methods. Ten CLAWN miniature swine received fully MHC-mismatched kidneys with 12 days (days 0-11) of FK506. Among these 10 recipients, 4 received 7 or 14 days of human-recombinant HGF starting at day 11. Graft function was assessed by daily serum creatinine and biopsies. Immunologic assays, including CD4/CD25 DP and FoxP3+ cells and development of antidonor antibodies, were performed.
Results. Without HGF, all six CLAWN recipients developed severe acute rejection (Cre >9 mg/dL) within 3 weeks of transplantation. In contrast, in the four animals that received HGF for 7 to 14 days, stable renal function was observed for more than 50 days, although all grafts were ultimately rejected by postoperative day 80. Percent FoxP3+ cells in the CD4+CD25+ double positive population (T regulatory cells) in peripheral blood monocyte cells decreased in recipients with FK506 induction monotherapy while no reduction was observed in recipients treated with FK506 and HGF.
Conclusion. This study demonstrates that in CLAWN swine treated with a dose of FK506 insufficient to induce tolerance across a fully MHC mismatched barrier, a short course of HGF may inhibit acute rejection while maintaining T regulatory cells. To our knowledge, this study provides the first evidence in a large animal transplantation model of HGF's immunoprotective effects.

AB The palmitoylation/depalmitoylation cycle of posttranslational processing is a potential therapeutic target for selectively inhibiting the growth of hematologic cancers with somatic NRAS mutations. To investigate this question at the single-cell level, we constructed murine stem cell virus vectors and assayed the growth of myeloid progenitors. Whereas cells expressing oncogenic N-Ras(G12D) formed cytokine-independent colonies and were hypersensitive to GMCSF, mutations within the N-Ras hypervariable region induced N-Ras mislocalization and attenuated aberrant progenitor growth. Exposing transduced hematopoietic cells and bone marrow from Nras and Kras mutant mice to the acyl protein thioesterase inhibitor palmostatin B had similar effects on protein localization and colony growth. Importantly, palmostatin B-mediated inhibition was selective for Nras mutant cells, and we mapped this activity to the hypervariable region. These data support the clinical development of depalmitoylation inhibitors as a novel class of rational therapeutics in hematologic malignancies with NRAS mutations. (Blood. 2012;119(4):1032-1035)

AB The brain and body respond to potential and actual stressful events by activating hormonal and neural mediators and modifying behaviors to adapt. Such responses help maintain physiological stability ("allostasis"). When behavioral or physiological stressors are frequent and/or severe, allostatic responses can become dysregulated and maladaptive ("allostatic load"). Allostatic load may alter brain networks both functionally and structurally. As a result, the brain's responses to continued/subsequent stressors are abnormal, and behavior and systemic physiology are altered in ways that can, in a vicious cycle, lead to further allostatic load. Migraine patients are continually exposed to such stressors, resulting in changes to central and peripheral physiology and function. Here we review how changes in brain states that occur as a result of repeated migraines may be explained by a maladaptive feedforward allostatic cascade model and how understanding migraine within the context of allostatic load model suggests alternative treatments for this often-debilitating disease.

AB Exercise benefits a variety of organ systems in mammals, and some of the best-recognized effects of exercise on muscle are mediated by the transcriptional co-activator PPAR-gamma co-activator-1 alpha (PGC1-alpha). Here we show in mouse that PGC1-alpha expression in muscle stimulates an increase in expression of FNDC5, a membrane protein that is cleaved and secreted as a newly identified hormone, irisin. Irisin acts on white adipose cells in culture and in vivo to stimulate UCP1 expression and a broad program of brown-fat-like development. Irisin is induced with exercise in mice and humans, and mildly increased irisin levels in the blood cause an increase in energy expenditure in mice with no changes in movement or food intake. This results in improvements in obesity and glucose homeostasis. Irisin could be therapeutic for human metabolic disease and other disorders that are improved with exercise.

AB Exercise has beneficial effects on human health, including protection against metabolic disorders such as diabetes(1). However, the cellular mechanisms underlying these effects are incompletely understood. The lysosomal degradation pathway, autophagy, is an intracellular recycling system that functions during basal conditions in organelle and protein quality control(2). During stress, increased levels of autophagy permit cells to adapt to changing nutritional and energy demands through protein catabolism(3). Moreover, in animal models, autophagy protects against diseases such as cancer, neurodegenerative disorders, infections, inflammatory diseases, ageing and insulin resistance(4-6). Here we show that acute exercise induces autophagy in skeletal and cardiac muscle of fed mice. To investigate the role of exercise-mediated autophagy in vivo, we generated mutant mice that show normal levels of basal autophagy but are deficient in stimulus (exercise- or starvation)-induced autophagy. These mice (termed BCL2 AAA mice) contain knock-in mutations in BCL2 phosphorylation sites (Thr69Ala, Ser70Ala and Ser84Ala) that prevent stimulus-induced disruption of the BCL2-beclin-1 complex and autophagy activation. BCL2 AAA mice show decreased endurance and altered glucose metabolism during acute exercise, as well as impaired chronic exercise-mediated protection against high-fat-diet-induced glucose intolerance. Thus, exercise induces autophagy, BCL2 is a crucial regulator of exercise- (and starvation)-induced autophagy in vivo, and autophagy induction may contribute to the beneficial metabolic effects of exercise.

AB Acute Lung Injury (ALI) is a syndrome with high associated mortality characterized by severe hypoxemia and pulmonary infiltrates in patients with critical illness. We conducted the first investigation to use the genome wide association (GWA) approach to identify putative risk variants for ALI. Genome wide genotyping was performed using the Illumina Human Quad 610 BeadChip. We performed a two-stage GWA study followed by a third stage of functional characterization. In the discovery phase (Phase 1), we compared 600 European American trauma-associated ALI cases with 2266 European American population-based controls. We carried forward the top 1% of single nucleotide polymorphisms (SNPs) at p<0.01 to a replication phase (Phase 2) comprised of a nested case-control design sample of 212 trauma-associated ALI cases and 283 at-risk trauma non-ALI controls from ongoing cohort studies. SNPs that replicated at the 0.05 level in Phase 2 were subject to functional validation (Phase 3) using expression quantitative trait loci (eQTL) analyses in stimulated Blymphoblastoid cell lines (B-LCL) in family trios. 159 SNPs from the discovery phase replicated in Phase 2, including loci with prior evidence for a role in ALI pathogenesis. Functional evaluation of these replicated SNPs revealed rs471931 on 11q13.3 to exert a cis-regulatory effect on mRNA expression in the PPFIA1 gene (p = 0.0021). PPFIA1 encodes liprin alpha, a protein involved in cell adhesion, integrin expression, and cell-matrix interactions. This study supports the feasibility of future multicenter GWA investigations of ALI risk, and identifies PPFIA1 as a potential functional candidate ALI risk gene for future research.

AB Background: Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies.
Methods: A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC) during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin.
Results: We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40) cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113). Case-patients had a median age of 52 years (range: 17-93) and were primarily female (77%) and Caucasian (77%). Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9) and 35.45 (SD = 12.89), respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies); skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin.
Conclusions: This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of life. No common underlying medical condition or infectious source was identified, similar to more commonly recognized conditions such as delusional infestation.

Here we report successful folding of multilayer DNA origami with helices arranged on a close-packed hexagonal lattice. This arrangement yields a higher density of helical packing and therefore higher resolution of spatial addressing than has been shown previously. We also demonstrate hybrid multilayer DNA origami with honeycomb-lattice, square-lattice, and hexagonal-lattice packing of helices all in one design. The availability of hexagonal close-packing of helices extends our ability to build complex structures using DNA nanotechnology.

AB Advances in next-generation sequencing (NGS) promise to facilitate diagnosis of inherited disorders. Although in research settings NGS has pinpointed causal alleles using segregation in large families, the key challenge for clinical diagnosis is application to single individuals. To explore its diagnostic use, we performed targeted NGS in 42 unrelated infants with clinical and biochemical evidence of mitochondrial oxidative phosphorylation disease. These devastating mitochondrial disorders are characterized by phenotypic and genetic heterogeneity, with more than 100 causal genes identified to date. We performed "MitoExome" sequencing of the mitochondrial DNA (mtDNA) and exons of similar to 1000 nuclear genes encoding mitochondrial proteins and prioritized rare mutations predicted to disrupt function. Because patients and healthy control individuals harbored a comparable number of such heterozygous alleles, we could not prioritize dominant-acting genes. However, patients showed a fivefold enrichment of genes with two such mutations that could underlie recessive disease. In total, 23 of 42 (55%) patients harbored such recessive genes or pathogenic mtDNA variants. Firm diagnoses were enabled in 10 patients (24%) who had mutations in genes previously linked to disease. Thirteen patients (31%) had mutations in nuclear genes not previously linked to disease. The pathogenicity of two such genes, NDUFB3 and AGK, was supported by complementation studies and evidence from multiple patients, respectively. The results underscore the potential and challenges of deploying NGS in clinical settings.

AB Background: The neurocircuits that process somatic sensory information in the dorsal horn of the spinal cord are still poorly understood, with one reason being the lack of Cre lines for genetically marking or manipulating selective subpopulations of dorsal horn neurons. Here we describe Tac2-Cre mice that were generated to express the Cre recombinase gene from the Tac2 locus. Tachykinin 2 (Tac2) encodes a neurotransmitter, neurokinin B (NKB).
Results: By crossing Tac2-Cre mice with ROSA26-tdTomato reporter mice, we directly visualized Tac2 lineage neurons in the dorsal root ganglia, the dorsal horn of the spinal cord, and many parts of the brain including the olfactory bulb, cerebral cortex, amygdala, hippocampus, habenula, hypothalamus, and cerebellum. This Tac2-Cre allele itself was a null allele for the Tac2 gene. Behavioral analyses showed that Tac2 homozygous null mice responded normally to a series of algogenic (pain-inducing) and pruritic (itch-inducing) stimuli.
Conclusions: Tac2-Cre mice are a useful tool to mark specific subsets of neurons in the sensory ganglia, the dorsal spinal cord, and the brain. These mice can also be used for future genetic manipulations to study the functions of Tac2-expressing neurons or the functions of genes expressed in these neurons.

AB The Transforming growth factor beta (Tgf-beta) pathway, by signaling via the activation of Smad transcription factors, induces the expression of many diverse downstream target genes thereby regulating a vast array of cellular events essential for proper development and homeostasis. In order for a specific cell type to properly interpret the Tgf-beta signal and elicit a specific cellular response, cell-specific transcriptional co-factors often cooperate with the Smads to activate a discrete set of genes in the appropriate temporal and spatial manner. Here, via a conditional knockout approach, we show that mice mutant for Forkhead Box O transcription factor FoxO1 exhibit an enamel hypomaturation defect which phenocopies that of the Smad3 mutant mice. Furthermore, we determined that both the FoxO1 and Smad3 mutant teeth exhibit changes in the expression of similar cohort of genes encoding enamel matrix proteins required for proper enamel development. These data raise the possibility that FoxO1 and Smad3 act in concert to regulate a common repertoire of genes necessary for complete enamel maturation. This study is the first to define an essential role for the FoxO family of transcription factors in tooth development and provides a new molecular entry point which will allow researchers to delineate novel genetic pathways regulating the process of biomineralization which may also have significance for studies of human tooth diseases such as amelogenesis imperfecta.

AB For subunit vaccines, adjuvants play a key role in shaping immunological memory. Nanoparticle (NP) delivery systems for antigens and/or molecular danger signals are promising adjuvants capable of promoting both cellular and humoral immune responses, but in most cases the mechanisms of action of these materials are poorly understood. Here, we studied the immune response elicited by NPs composed of multilamellar "stapled" lipid vesicles carrying a recombinant Plasmodium vivax circumsporozoite antigen, VMP001, both entrapped in the aqueous core and anchored to the lipid bilayer surfaces. Immunization with these particles and monophosphoryl lipid A (MPLA), a US Food and Drug Administration-approved immunostimulatory agonist for Toll-like receptor-4, promoted high-titer, high-avidity antibody responses against VMP001, lasting more than 1 y in mice at 10-fold lower doses than conventional adjuvants. Compared to soluble VMP001 mixed with MPLA, VMP001-NPs promoted broader humoral responses, targeting multiple epitopes of the protein and a more balanced Th1/Th2 cytokine profile from antigen-specific T cells. To begin to understand the underlying mechanisms, we examined components of the B-cell response and found that NPs promoted robust germinal center (GC) formation at low doses of antigen where no GC induction occurred with soluble protein immunization, and that GCs nucleated near depots of NPs accumulating in the draining lymph nodes over time. In parallel, NP vaccination enhanced the expansion of antigen-specific follicular helper T cells (T-fh), compared to vaccinations with soluble VMP001 or alum. Thus, NP vaccines may be a promising strategy to enhance the durability, breadth, and potency of humoral immunity by enhancing key elements of the B-cell response.

AB Base excision repair of genotoxic nucleobase lesions in the genome is critically dependent upon the ability of DNA glycosylases to locate rare sites of damage embedded in a vast excess of undamaged DNA, using only thermal energy to fuel the search process. Considerable interest surrounds the question of how DNA glycosylases translocate efficiently along DNA while maintaining their vigilance for target damaged sites. Here, we report the observation of strandwise translocation of 8-oxoguanine DNA glycosylase, MutM, along undamaged DNA. In these complexes, the protein is observed to translocate by one nucleotide on one strand while remaining untranslocated on the complementary strand. We further report that alterations of single base-pairs or a single amino acid substitution (R112A) can induce strandwise translocation. Molecular dynamics simulations confirm that MutM can translocate along DNA in a strandwise fashion. These observations reveal a previously unobserved mode of movement for a DNA-binding protein along the surface of DNA.

AB The decision between survival and death in cells exposed to TNF relies on a highly regulated equilibrium between proapoptotic and antiapoptotic factors. The TNF-activated antiapoptotic response depends on several transcription factors, including NF-kappa B and its RelA/p65 subunit, that are activated through phosphorylation-mediated degradation of I kappa B inhibitors, a process controlled by the I kappa B kinase complex. Genetic studies in mice have identified the I kappa B kinase-related kinase TANK-binding kinase 1 (TBK1; also called NAK or T2K) as an additional regulatory molecule that promotes survival downstream of TNF, but the mechanism through which TBK1 exerts its survival function has remained elusive. Here we show that TBK1 triggers an antiapoptotic response by controlling a specific RelA/p65 phosphorylation event. TBK1-induced RelA phosphorylation results in inducible expression of plasminogen activator inhibitor-2 (PAI-2), a member of the serpin family with known antiapoptotic activity. PAI-2 limits caspase-3 activation through stabilization of transglutaminase 2 (TG2), which cross-links and inactivates procaspase-3. Importantly, Tg2(-/-) mice were found to be more susceptible to apoptotic cell death in two models of TNF-dependent acute liver injury. Our results establish PAI-2 and TG2 as downstream mediators in the antiapoptotic response triggered upon TBK1 activation.

AB Pulmonary arterial hypertension (PAH) is a life-threatening disease which, if untreated, leads to right ventricular failure and often death. Several effective therapies are now available for PAH, including endothelin receptor antagonists, phosphodiesterase-5 inhibitors, and prostacyclin analogs. The prostacyclin analog treprostinil has proven efficacious when delivered by subcutaneous or intravenous infusion, and most recently by inhalation. Inhaled treprostinil has been shown to be 64%-72% bioavailable in healthy volunteers. Pilot clinical studies have elucidated the acute hemodynamic effects and relative pulmonary selectivity of this agent, as well as established target dosing in PAH and nonoperable chronic thromboembolic PAH. Likewise, chronically administered inhaled treprostinil resulted in clinical and hemodynamic improvement. Both pilot studies confirmed a satisfactory safety profile in patients with PAH. The pivotal Phase III trial, TRIUMPH-I, demonstrated the efficacy and safety of inhaled treprostinil (target dose of 54 mu g four times daily) in PAH patients added to background therapies of bosentan or sildenafil, as assessed by improvements in the primary endpoint, peak six-minute walk distance (median placebo-corrected treatment effect of 20 m), as well as select secondary endpoints. Inhaled treprostinil is approved by the US Food and Drug Administration for patients with World Health Organization Group I PAH to improve exercise ability. Studies establishing effectiveness included predominately patients with New York Heart Association functional class III symptoms and etiologies of idiopathic or heritable PAH (56%) or PAH associated with connective tissue diseases (33%).

AB White adipose tissues are composed mainly of white fat cells adipocytes), which play a key role in energy storage and metabolism. White adipocytes are terminally differentiated postmitotic cells and arise from their progenitor cells (preadipocytes) or mesenchymal stem cells residing in white adipose tissues. Thus, white adipocyte number is most likely controlled by the rate of preadipocyte proliferation, which may contribute to the etiology of obesity. However, little is known about the molecular mechanisms that regulate preadipocyte proliferation during adipose tissue development. Necdin, which is expressed predominantly in postmitotic neurons, is a pleiotropic protein that possesses anti-mitotic and pro-survival activities. Here we show that necdin functions as an intrinsic regulator of white preadipocyte proliferation in developing adipose tissues. Necdin is expressed in early preadipocytes or mesenchymal stem cells residing in the stromal compartment of white adipose tissues in juvenile mice. Lentivirus-mediated knockdown of endogenous necdin expression in vivo in adipose tissues markedly increases fat mass in juvenile mice fed a high-fat diet until adulthood. Furthermore, necdin-null mutant mice exhibit a greater expansion of adipose tissues due to adipocyte hyperplasia than wild-type mice when fed the high-fat diet during the juvenile and adult periods. Adipose stromal-vascular cells prepared from necdin-null mice differentiate in vitro into a significantly larger number of adipocytes in response to adipogenic inducers than those from wild-type mice. These results suggest that necdin prevents excessive preadipocyte proliferation induced by adipogenic stimulation to control white adipocyte number during adipose tissue development.

TI eNOS Protects from Atherosclerosis Despite Relevant Superoxide

ATHEROSCLEROSIS; LEUKOCYTE ADHESION; PLATELET-ADHESION; LESION FORMATION
AB Background: All three nitric oxide synthase (NOS) isoforms are expressed in atherosclerotic plaques. NOS enzymes in general catalyse NO production. However, under conditions of substrate and cofactor deficiency, the enzyme directly catalyse superoxide formation. Considering this alternative chemistry, the effects of NOS on key events in spontaneous hyperlipidemia driven atherosclerosis have not been investigated yet. Here, we evaluate how endothelial nitric oxide synthase (eNOS) modulates leukocyte/endothelial-(L/E) and platelet/endothelial-(P/E) interactions in atherosclerosis and the production of nitric oxide (NO) and superoxide by the enzyme.
Principal Findings: Intravital microscopy (IVM) of carotid arteries revealed significantly increased L/E-interactions in apolipoproteinE/eNOS double knockout mice (apoE(-/-)/eNOS(-/-)), while P/E-interactions did not differ, compared to apoE(-/-). eNOS deficiency increased macrophage infiltration in carotid arteries and vascular cell adhesion molecule-1 (VCAM-1) expression, both in endothelial and smooth muscle cells. Despite the expression of other NOS isoforms (inducible NOS, iNOS and neuronal NOS, nNOS) in plaques, Electron Spin Resonance (ESR) measurements of NO showed significant contribution of eNOS to total circulating and vascular wall NO production. Pharmacological inhibition and genetic deletion of eNOS reduced vascular superoxide production, indicating uncoupling of the enzyme in apoE(-/-) vessels.
Conclusion: Overt plaque formation, increased vascular inflammation and L/E-interactions are associated with significant reduction of superoxide production in apoE(-/-)/eNOS(-/-) vessels. Therefore, lack of eNOS does not cause an automatic increase in oxidative stress. Uncoupling of eNOS occurs in apoE(-/-) atherosclerosis but does not negate the enzyme's strong protective effects.

AB Background: This study investigates whether the incidence of new-onset diabetes mellitus (DM) is associated with statin use among postmenopausal women participating in the Women's Health Initiative (WHI).
Methods: The WHI recruited 161 808 postmenopausal women aged 50 to 79 years at 40 clinical centers across the United States from 1993 to 1998 with ongoing follow-up. The current analysis includes data through 2005. Statin use was captured at enrollment and year 3. Incident DM status was determined annually from enrollment. Cox proportional hazards models were used to estimate the risk of DM by statin use, with adjustments for propensity score and other potential confounding factors. Subgroup analyses by race/ethnicity, obesity status, and age group were conducted to uncover effect modification.
Results: This investigation included 153 840 women without DM and no missing data at baseline. At baseline, 7.04% reported taking statin medication. There were 10 242 incident cases of self-reported DM over 1 004 466 person-years of follow-up. Statin use at baseline was associated with an increased risk of DM(hazard ratio [HR], 1.71; 95% CI, 1.61-1.83). This association remained after adjusting for other potential confounders (multivariate-adjusted HR, 1.48; 95% CI, 1.38-1.59) and was observed for all types of statin medications. Subset analyses evaluating the association of self-reported DM with longitudinal measures of statin use in 125 575 women confirmed these findings.
Conclusions: Statin medication use in postmenopausal women is associated with an increased risk for DM. This may be a medication class effect. Further study by statin type and dose may reveal varying risk levels for new-onset DM in this population.

AB Background: Sudden exposure to high iodide levels may cause thyroid dysfunction. Despite compelling biological plausibility and clinical implication, the association between iodinated contrast media exposure and incident hyperthyroidism and hypothyroidism has not been rigorously studied.
Methods: We performed a nested case-control study of patients treated between January 1, 1990, and June 30, 2010, who did not have preexisting hyperthyroidism or hypothyroidism. In parallel analyses, incident hyperthyroid or hypothyroid cases were defined by a change in thyrotropin level from normal (at baseline) to low or high (follow-up measurement). Euthyroid controls were selected using an incidence density sampling approach and were matched to cases on the basis of age, sex, race/ethnicity, estimated glomerular filtration rate, follow-up thyrotropin measurement date, and interval between baseline and the follow-up thyrotropin measurement date. Iodinated contrast media exposure was assessed using claims data for contrast-enhanced computed tomography or cardiac catheterization.
Results: In total, 178 and 213 incident hyperthyroid and hypothyroid cases, respectively, were matched to 655 and 779 euthyroid controls, respectively. Iodinated contrast media exposure was associated with incident hyperthyroidism (odds ratio [OR], 1.98; 95% CI, 1.08-3.60), but a statistically significant association with incident hypothyroidism was not observed (OR, 1.58; 95% CI, 0.952.62). In prespecified secondary analysis, iodinated contrast media exposure was associated with incident overt hyperthyroidism (follow-up thyrotropin level <= 0.1 mIU/L; OR, 2.50; 95% CI, 1.06-5.93) and with incident overt hypothyroidism (follow-up thyrotropin level >10 mIU/L; OR, 3.05; 95% CI, 1.07-8.72).
Conclusion: Iodinated contrast media exposure is associated with subsequent development of incident hyperthyroidism and incident overt hypothyroidism.

AB AIM: To investigate the influence of repeated water avoidance stress (rWAS) on the visceromotor response (VMR) to colorectal distension (CRD) and the modulation of the response by a prebiotic diet in rats using a novel surgery-free method of solid-state manometry.
METHODS: Male Wistar rats fed a standard diet with or without 4% enzyme-treated rice fiber (ERF) for 5 wk were subjected to rWAS (1 h daily x 10 d) or no stress. The VMR to graded phasic CRD was assessed by intraluminal colonic pressure recording on days 0 (baseline), 1 and 10 (45 min) and 11 (24 h) after rWAS and expressed as percentage change from baseline. Cecal content of short chain fatty acids and distal colonic histology were assessed on day 11.
RESULTS: WAS on day 1 reduced the VMR to CRD at 40 and 60 mmHg similarly by 28.9% +/- 6.6% in both diet groups. On day 10, rWAS-induced reduction of VMR occurred only at 40 mmHg in the standard diet group (36.2% +/- 17.8%) while in the ERF group VMR was lowered at 20, 40 and 60 mmHg by 64.9% +/- 20.9%, 49.3% +/- 11.6% and 38.9% +/- 7.3% respectively. The visceral analgesia was still observed on day 11 in ERF- but not in standard diet-fed rats. By contrast the non-stressed groups (standard or ERF duet) exhibited no changes in VMR to CRD. In standard diet-fed rats, rWAS induced mild colonic histological changes that were absent in ERF-fed rats exposed to stress compared to non-stressed rats. The reduction of cecal content of isobutyrate and total butyrate, but not butyrate alone, was correlated with lower visceral pain response. Additionally, ERF diet increased rWAS-induced defecation by 26% and 75% during the first 0-15 min and last 15-60 min, respectively, compared to standard diet, and reduced rats' body weight gain by 1.3 fold independently of their stress status.
CONCLUSION: These data provide the first evidence of psychological stress-related visceral analgesia in rats that was enhanced by chronic intake of ERF prebiotic. (C) 2012 Baishideng. All rights reserved.

AB Secondary neutron fluence created during proton therapy can be a significant source of radiation exposure in organs distant from the treatment site, especially in pediatric patients. Various published studies have used computational phantoms to estimate neutron equivalent doses in proton therapy. In these simulations, whole-body patient representations were applied considering either generic whole-body phantoms or generic age-and gender-dependent phantoms. No studies to date have reported using patient-specific geometry information. The purpose of this study was to estimate the effects of patient-phantom matching when using computational pediatric phantoms. To achieve this goal, three sets of phantoms, including different ages and genders, were compared to the patients' whole-body CT. These sets consisted of pediatric age-specific reference, age-adjusted reference and anatomically sculpted phantoms. The neutron equivalent dose for a subset of out-of-field organs was calculated using the GEANT4 Monte Carlo toolkit, where proton fields were used to irradiate the cranium and the spine of all phantoms and the CT-segmented patient models. The maximum neutron equivalent dose per treatment absorbed dose was calculated and found to be on the order of 0 to 5 mSv Gy(-1). The relative dose difference between each phantom and their respective CT-segmented patient model for most organs showed a dependence on how close the phantom and patient heights were matched. The weight matching was found to have much smaller impact on the dose accuracy except for very heavy patients. Analysis of relative dose difference with respect to height difference suggested that phantom sculpting has a positive effect in terms of dose accuracy as long as the patient is close to the 50th percentile height and weight. Otherwise, the benefit of sculpting was masked by inherent uncertainties, i.e. variations in organ shapes, sizes and locations. Other sources of uncertainty included errors associated with beam positioning, neutron weighting factor definition and organ segmentation. This work demonstrated the importance of hybrid phantom height matching for more accurate organ dose calculation in proton therapy and the potential limitations of reference phantoms released by regulatory bodies for radiation therapy applications.

AB Purpose
A phase I/II study of cixutumumab (IMC-A12) in children with refractory solid tumors was conducted. This study was designed to assess the toxicities, pharmacokinetics, and pharmacodynamics of cixutumumab in children to determine a recommended phase II dose and to assess antitumor activity in Ewing sarcoma (ES).
Patients and Methods
Pediatric patients with relapsed or refractory solid tumors were treated with cixutumumab as a 1-hour intravenous infusion once per week. Two dose levels-6 and 9 mg/kg-were evaluated using a standard three-plus-three cohort design. Patients with refractory ES were treated in an expanded phase II cohort at each dose level.
Results
Forty-seven eligible patients with a median age of 15 years (range, 4 to 28 years) were enrolled. Twelve patients were treated in the dose-finding phase. Hematologic and nonhematologic toxicities were generally mild and infrequent. Dose-limiting toxicities included grade 4 thrombocytopenia at 6 mg/kg and grade 3 dehydration at 9 mg/kg. Mean trough concentration (+/- standard deviation) at 9 mg/kg was 106 +/- 57 mu g/mL, which exceeded the effective trough concentration of 60 mu g/mL observed in xenograft models. Three patients with ES had confirmed partial responses: one of 10 at 6 mg/kg and two of 20 at 9 mg/kg. Serum insulin-like growth factor I (IGF-I) levels consistently increased after one dose of cixutumumab. Tumor IGF-I receptor expression by immunohistochemistry did not correlate with response in patients with ES.
Conclusion
Cixutumumab is well tolerated in children with refractory solid tumors. The recommended phase II dose is 9 mg/kg. Limited single-agent activity of cixutumumab was seen in ES.

AB Purpose
This phase I dose-escalation study investigated the maximum-tolerated dose (MTD), safety, preliminary activity, pharmacokinetics (PK), and pharmacodynamics of BKM120, a potent and highly specific oral pan-Class I PI3K inhibitor.
Patients and Methods
Thirty-five patients with advanced solid tumors received daily BKM120 12.5 to 150 mg. Dose escalation was guided by a Bayesian logistic regression model with overdose control. Assessments included archival tumor molecular status, response by Response Evaluation Criteria in Solid Tumors (RECIST), positron emission tomography tracer uptake ([F-18] fluorodeoxyglucose positron emission tomography [FDG-PET]), fasting plasma C-peptide, and phosphorylated ribosomal protein S6 (pS6) in skin biopsies.
Results
Overall, treatment was well tolerated. Dose-limiting toxicities were grade 2 mood alteration (80 mg), grade 3 epigastralgia, grade 3 rash, grade 2 and grade 3 mood alteration (100 mg), and two grade 4 hyperglycemia (150 mg). The MTD was 100 mg/d. Frequent treatment-related adverse events included rash, hyperglycemia, diarrhea, anorexia, and mood alteration (37% each); nausea (31%); fatigue (26%); pruritus (23%); and mucositis (23%). BKM120 demonstrated rapid absorption, half-life of similar to 40 hours, similar to three-fold steady-state accumulation, dose-proportional exposure, and moderate interpatient variability. One patient demonstrated a confirmed partial response (triple-negative breast cancer); seven patients (20%) were on study for >= 8 months. BKM120 demonstrated dose-dependent pharmacodynamic effects on [F-18] FDG-PET, fasting C-peptide, fasting blood glucose, and pS6. No significant trends were seen to correlate tumor molecular alterations with clinical activity.
Conclusion
This study demonstrates feasibility and proof-of-concept of class I PI3K inhibition in patients with advanced cancers. BKM120, at the MTD of 100 mg/d, is safe and well tolerated, with a favorable PK profile, clear evidence of target inhibition, and preliminary antitumor activity.

TI Impact of Long-Term Serum Platinum Concentrations on Neuro- and
Ototoxicity in Cisplatin-Treated Survivors of Testicular Cancer

AB Purpose
Cisplatin-induced neurotoxicity and ototoxicity (NTX) are important adverse effects after chemotherapy for testicular cancer (TC). Although serum platinum is measurable years after therapy, its impact on NTX has not been evaluated.
Patients and Methods
In all, 169 cisplatin-treated survivors of TC provided blood samples at Survey I and reported NTX during Survey I (1998-2002) and Survey II (2007-2008). Serum platinum was quantified by inductively coupled plasma mass spectrometry. Patient-reported outcomes were evaluated with the Scale for Chemotherapy-Induced Neurotoxicity (SCIN), regarding the extent of symptom bother as 0, "not at all"; 1, "a little"; 2, "quite a bit"; or 3, "very much." Summing the six symptom scores yielded a total SCIN score of 0 to 18. Categorizing total SCIN scores into quartiles yielded similar-sized groups with increasing symptoms. Multivariate ordinal logistic regression analyses evaluated associations between NTX and long-term serum platinum levels, adjusting for cisplatin dose, dosing schedule, and age.
Results
At Survey I, a significant four-to five-fold association with total SCIN score emerged for the highest serum platinum quartile (odds ratio [OR], 4.69; 95% CI, 1.82 to 12.08). Paresthesias and Raynaud's syndrome (hands and feet) showed significant two-to four-fold increased risks with the highest platinum quartile. At Survey II, total SCIN score remained significantly associated with the highest platinum quartile (OR, 4.28; 95% CI, 1.36 to 13.48). Paresthesias (hands and feet) and tinnitus showed significant three-to four-fold increased risks for the highest platinum quartile. Cumulative cisplatin dose was not associated with total SCIN score or individual SCIN symptoms in multivariate analyses.
Conclusion
Here we document a significant relationship between increasing levels of residual serum platinum and NTX severity after adjusting for initial cisplatin dose.

TI RAS Mutations Are Associated With the Development of Cutaneous Squamous
Cell Tumors in Patients Treated With RAF Inhibitors

DT Article
ID NONMELANOMA SKIN CANCERS; ACTINIC KERATOSIS; GENE-MUTATIONS; MELANOMA;
BRAF; SORAFENIB; CARCINOMA; PATHWAY; KERATOACANTHOMA; PROGRESSION
AB Purpose
RAF inhibitors are effective against melanomas with BRAF V600E mutations but may induce keratoacanthomas (KAs) and cutaneous squamous cell carcinomas (cSCCs). The potential of these agents to promote secondary malignancies is concerning. We analyzed cSCC and KA lesions for genetic mutations in an attempt to identify an underlying mechanism for their formation.
Methods
Four international centers contributed 237 KA or cSCC tumor samples from patients receiving an RAF inhibitor (either vemurafenib or sorafenib; n = 19) or immunosuppression therapy (n = 53) or tumors that developed spontaneously (n = 165). Each sample was profiled for 396 known somatic mutations across 33 cancer-related genes by using a mass spectrometric-based genotyping platform.
Results
Mutations were detected in 16% of tumors (38 of 237), with five tumors harboring two mutations. Mutations in TP53, CDKN2A, HRAS, KRAS, and PIK3CA were previously described in squamous cell tumors. Mutations in MYC, FGFR3, and VHL were identified for the first time. A higher frequency of activating RAS mutations was found in tumors from patients treated with an RAF inhibitor versus populations treated with a non-RAF inhibitor (21.1% v 3.2%; P < .01), although overall mutation rates between treatment groups were similar (RAF inhibitor, 21.1%; immunosuppression, 18.9%; and spontaneous, 17.6%; P = not significant). Tumor histology (KA v cSCC), tumor site (head and neck v other), patient age (<= 70 v >70 years), and sex had no significant impact on mutation rate or type.
Conclusion
Squamous cell tumors from patients treated with an RAF inhibitor have a distinct mutational profile that supports a mechanism of therapy-induced tumorigenesis in RAS-primed cells. Conceivably, cotargeting of MEK together with RAF may reduce or prevent formation of these tumors.

AB A major priority in HIV vaccine research is the development of an immunogen to elicit broadly neutralizing antibodies (NAbs). Monoclonal antibody (mAb) b12 is one of now several broadly neutralizing mAbs that bind epitopes overlapping the CD4-binding site (CD4bs) on HIV-1 gpl 20 and that serve as templates to engineer effective immunogens. We are exploring a strategy whereby extra glycans are incorporated onto gp120 to occlude the epitopes of non-neutralizing mAbs while maintaining exposure of the b12 site. Immunizing with these so-called hyperglycosylated gp120s is hypothesized to preferentially elicit b12-like NAbs. Here, the effects of two adjuvants, monophosphoryl lipid A (MPL) and Quil A, on eliciting b12-like responses when formulated with a new hyperglycosylated mutant, Delta N2mCHO(Q105N), is presented. Sera from Delta N2mCHO(Q105N)_MPL immunized animals bound the homologous antigen Delta N2mCHO(Q105N) with greater preference than sera from Delta N2mCHO(Q105N)_QuilA immunized animals, demonstrating the modulation of antibody fine specificity by these two adjuvants. We also found that sera from Delta N2mCHO(Q105N)_QuilA immunized animals bound best to a resurfaced HIV gpl 20 core protein on which non-CD4bs epitopes are substituted with non-HIV residues, suggesting that these sera contain a relatively larger fraction of CD4bs-specific antibodies. Consistent with these data, inhibition assays revealed epitope overlap with the binding sites of the CD4bs-specific antibodies b12, b13 and VRCO3. Unexpectedly, these sera did not exhibit significant neutralizing activity against a set of HIV-1 primary strains. Our results show that although formulating mutant Delta N2mCHO(Q105N) with Quil A promotes the elicitation of CD4bs-directed antibodies relative to wild-type gp120, tweaking of the immunization regimen is needed to yield robust, CD4bs-focused NAbs.

AB Purpose: To improve ischemic stroke outcome prediction using imaging information from a prospective cohort who received admission CT angiography (CTA).
Methods: In a prospectively designed study, 649 stroke patients diagnosed with acute ischemic stroke had admission NIH stroke scale scores, noncontrast CT (NCCT), CTA, and 6-month outcome assessed using the modified Rankin scale (mRS) scores. Poor outcome was defined as mRS>2. Strokes were classified as "major'' by the (1) Alberta Stroke Program Early CT Score (ASPECTS+) if NCCT ASPECTS was <= 7; (2) Boston Acute Stroke Imaging Scale (BASIS+) if they were ASPECTS+ or CTA showed occlusion of the distal internal carotid, proximal middle cerebral, or basilar arteries; and (3) NIHSS for scores>10.
Results: Of 649 patients, 253 (39.0%) had poor outcomes. NIHSS, BASIS, and age, but not ASPECTS, were independent predictors of outcome. BASIS and NIHSS had similar sensitivities, both superior to ASPECTS (p<0.0001). Combining NIHSS with BASIS was highly predictive: 77.6% (114/147) classified as NIHSS>10/BASIS+ had poor outcomes, versus 21.5% (77/358) with NIHSS <= 10/BASIS- (p<0.0001), regardless of treatment. The odds ratios for poor outcome is 12.6 (95% CI: 7.9 to 20.0) in patients who are NIHSS>10/BASIS+ compared to patients who are NIHSS <= 10/BASIS-; the odds ratio is 5.4 (95% CI: 3.5 to 8.5) when compared to patients who are only NIHSS>10 or BASIS+.
Conclusions: BASIS and NIHSS are independent outcome predictors. Their combination is stronger than either instrument alone in predicting outcomes. The findings suggest that CTA is a significant clinical tool in routine acute stroke assessment.

AB Target of rapamycin (TOR) kinase is an evolutionarily conserved master regulator that integrates energy, nutrients, growth factors, and stress signals to promote survival and growth in all eukaryotes. The reported land plant resistance to rapamycin and the embryo lethality of the Arabidopsis tor mutants have hindered functional dissection of TOR signaling in plants. We developed sensitive cellular and seedling assays to monitor endogenous Arabidopsis TOR activity based on its conserved S6 kinase (S6K) phosphorylation. Surprisingly, rapamycin effectively inhibits Arabidopsis TOR-S6K1 signaling and retards glucose-mediated root and leaf growth, mimicking estradiol-inducible tor mutants. Rapamycin inhibition is relieved in transgenic plants deficient in Arabidopsis FK506-binding protein 12 (FKP12), whereas FKP12 overexpression dramatically enhances rapamycin sensitivity. The role of Arabidopsis FKP12 is highly specific as overexpression of seven closely related FKP proteins fails to increase rapamycin sensitivity. Rapamycin exerts TOR inhibition by inducing direct interaction between the TOR-FRB (FKP-rapamycin binding) domain and FKP12 in plant cells. We suggest that variable endogenous FKP12 protein levels may underlie the molecular explanation for longstanding enigmatic observations on inconsistent rapamycin resistance in plants and in various mammalian cell lines or diverse animal cell types. Integrative analyses with rapamycin and conditional tor and fkp12 mutants also reveal a central role of glucose-TOR signaling in root hair formation. Our studies demonstrate the power of chemical genetic approaches in the discovery of previously unknown and pivotal functions of glucose-TOR signaling in governing the growth of cotyledons, true leaves, petioles, and primary and secondary roots and root hairs.

AB Pancreatic cancer is a leading cause of cancer-related death, largely due to metastatic dissemination. We investigated pancreatic cancer progression by utilizing a mathematical framework of metastasis formation together with comprehensive data of 228 patients, 101 of whom had autopsies. We found that pancreatic cancer growth is initially exponential. After estimating the rates of pancreatic cancer growth and dissemination, we determined that patients likely harbor metastases at diagnosis and predicted the number and size distribution of metastases as well as patient survival. These findings were validated in an independent database. Finally, we analyzed the effects of different treatment modalities, finding that therapies that efficiently reduce the growth rate of cells earlier in the course of treatment appear to be superior to upfront tumor resection. These predictions can be validated in the clinic. Our interdisciplinary approach provides insights into the dynamics of pancreatic cancer metastasis and identifies optimum therapeutic interventions.

AB Low-level laser light therapy (LLLT) exerts beneficial effects on motor and histopathological outcomes after experimental traumatic brain injury (TBI), and coherent near-infrared light has been reported to improve cognitive function in patients with chronic TBI. However, the effects of LLLT on cognitive recovery in experimental TBI are unknown. We hypothesized that LLLT administered after controlled cortical impact (CCI) would improve post-injury Morris water maze (MWM) performance. Low-level laser light (800 nm) was applied directly to the contused parenchyma or transcranially in mice beginning 60-80 min after CCI. Injured mice treated with 60 J/cm(2) (500 mW/cm(2)x2 min) either transcranially or via an open craniotomy had modestly improved latency to the hidden platform (p<0.05 for group), and probe trial performance (p<0.01) compared to non-treated controls. The beneficial effects of LLLT in open craniotomy mice were associated with reduced microgliosis at 48h (21.8 +/- 2.3 versus 39.2 +/- 4.2 IbA-1 + cells/200 x field, p<0.05). Little or no effect of LLLT on post-injury cognitive function was observed using the other doses, a 4-h administration time point and 7-day administration of 60 J/cm(2). No effect of LLLT (60 J/cm(2) open craniotomy) was observed on post-injury motor function (days 1-7), brain edema (24h), nitrosative stress (24h), or lesion volume (14 days). Although further dose optimization and mechanism studies are needed, the data suggest that LLLT might be a therapeutic option to improve cognitive recovery and limit inflammation after TBI.

AB Lifelong antibody responses to vaccination require reorganization of lymphoid tissue and dynamic intercellular communication called the germinal center reaction. B lymphocytes undergo cellular polarization during antigen stimulation, acquisition, and presentation, which are critical steps for initiating humoral immunity. Here, we show that germinal center B lymphocytes asymmetrically segregate the transcriptional regulator Bcl6, the receptor for interleukin-21, and the ancestral polarity protein atypical protein kinase C to one side of the plane of division, generating unequal inheritance of fate-altering molecules by daughter cells. Germinal center B lymphocytes from mice with a defect in leukocyte adhesion fail to divide asymmetrically. These results suggest that motile cells lacking constitutive attachment can receive provisional polarity cues from the microenvironment to generate daughter cell diversity and self-renewal.

AB Myc is an oncogenic transcription factor frequently dysregulated in human cancer. To identify pathways supporting the Myc oncogenic program, we used a genome-wide RNA interference screen to search for Myc-synthetic lethal genes and uncovered a role for the SUMO-activating enzyme (SAE1/2). Loss of SAE1/2 enzymatic activity drives synthetic lethality with Myc. Inactivation of SAE2 leads to mitotic catastrophe and cell death upon Myc hyperactivation. Mechanistically, SAE2 inhibition switches a transcriptional subprogram of Myc from activated to repressed. A subset of these SUMOylation-dependent Myc switchers (SMS genes) is required for mitotic spindle function and to support the Myc oncogenic program. SAE2 is required for growth of Myc-dependent tumors in mice, and gene expression analyses of Myc-high human breast cancers suggest that low SAE1 and SAE2 abundance in the tumors correlates with longer metastasis-free survival of the patients. Thus, inhibition of SUMOylation may merit investigation as a possible therapy for Myc-driven human cancers.

AB Hematopoietic stem cells (HSCs) interact with osteoblastic, stromal, and vascular components of the BM hematopoietic microenvironment (HM) that are required for the maintenance of long-term self-renewal in vivo. Osteoblasts have been reported to be a critical cell type making up the HSC niche in vivo. Rac1 GTPase has been implicated in adhesion, spreading, and differentiation of osteoblast cell lines and is critical for HSC engraftment and retention. Recent data suggest a differential role of GTPases in endosteal/osteoblastic versus perivascular niche function. However, whether Rac signaling pathways are also necessary in the cell-extrinsic control of HSC function within the HM has not been examined. In the present study, genetic and inducible models of Rac deletion were used to demonstrate that Rac depletion causes impaired proliferation and induction of apoptosis in the OP9 cell line and in primary BM stromal cells. Deletion of Rac proteins caused reduced trabecular and cortical long bone growth in vivo. Surprisingly, HSC function and maintenance of hematopoiesis in vivo was preserved despite these substantial cell-extrinsic changes. These data have implications for therapeutic strategies to target Rac signaling in HSC mobilization and in the treatment of leukemia and provide clarification to our evolving concepts of HSC-HM interactions.

AB The MUC1-C oncoprotein is aberrantly expressed in most multiple myeloma cells. However, the functional significance of MUC1-C expression in multiple myeloma is not known. The present studies demonstrate that treatment of multiple myeloma cells with a MUC1-C inhibitor is associated with increases in reactive oxygen species (ROS), oxidation of mitochondrial cardiolipin, and loss of the mitochondrial transmembrane potential. The MUC1-C inhibitor-induced increases in ROS were also associated with downregulation of the p53-inducible regulator of glycolysis and apoptosis (TIGAR). In concert with the decrease in TIGAR expression, which regulates the pentose phosphate pathway, treatment with the MUC1-C inhibitor reduced production of NADPH, and in turn glutathione (GSH) levels. TIGAR protects against oxidative stress-induced apoptosis. The suppression of TIGAR and NADPH levels thus contributed to ROS-mediated late apoptosis/necrosis of multiple myeloma cells. These findings indicate that multiple myeloma cells are dependent on MUC1-C and TIGAR for maintenance of redox balance and that targeting MUC1-C activates a cascade involving TIGAR suppression that contributes to multiple myeloma cell death.

TI RAS Mutations in Cutaneous Squamous-Cell Carcinomas in Patients Treated
with BRAF Inhibitors

AB BACKGROUND
Cutaneous squamous-cell carcinomas and keratoacanthomas are common findings in patients treated with BRAF inhibitors.
METHODS
We performed a molecular analysis to identify oncogenic mutations (HRAS, KRAS, NRAS, CDKN2A, and TP53) in the lesions from patients treated with the BRAF inhibitor vemurafenib. An analysis of an independent validation set and functional studies with BRAF inhibitors in the presence of the prevalent RAS mutation was also performed.
RESULTS
Among 21 tumor samples, 13 had RAS mutations (12 in HRAS). In a validation set of 14 samples, 8 had RAS mutations (4 in HRAS). Thus, 60% (21 of 35) of the specimens harbored RAS mutations, the most prevalent being HRAS Q61L. Increased proliferation of HRAS Q61L-mutant cell lines exposed to vemurafenib was associated with mitogen-activated protein kinase (MAPK)-pathway signaling and activation of ERK-mediated transcription. In a mouse model of HRAS Q61L-mediated skin carcinogenesis, the vemurafenib analogue PLX4720 was not an initiator or a promoter of carcinogenesis but accelerated growth of the lesions harboring HRAS mutations, and this growth was blocked by concomitant treatment with a MEK inhibitor.
CONCLUSIONS
Mutations in RAS, particularly HRAS, are frequent in cutaneous squamous-cell carcinomas and keratoacanthomas that develop in patients treated with vemurafenib. The molecular mechanism is consistent with the paradoxical activation of MAPK signaling and leads to accelerated growth of these lesions.

TI Recurrent Somatic DICER1 Mutations in Nonepithelial Ovarian Cancers
SO NEW ENGLAND JOURNAL OF MEDICINE
LA English
DT Article
ID GRANULOSA-CELL TUMORS; RNASE-III; EXPRESSION; MICRORNAS; PROGNOSIS;
SELECTION; DROSHA; FOXL2
AB BACKGROUND
Germline truncating mutations in DICER1, an endoribonuclease in the RNase III family that is essential for processing microRNAs, have been observed in families with the pleuropulmonary blastoma-family tumor and dysplasia syndrome. Mutation carriers are at risk for nonepithelial ovarian tumors, notably sex cord-stromal tumors.
METHODS
We sequenced the whole transcriptomes or exomes of 14 nonepithelial ovarian tumors and noted closely clustered mutations in the region of DICER1 encoding the RNase IIIb domain of DICER1 in four samples. We then sequenced this region of DICER1 in additional ovarian tumors and in certain other tumors and queried the effect of the mutations on the enzymatic activity of DICER1 using in vitro RNA cleavage assays.
RESULTS
DICER1 mutations in the RNase IIIb domain were found in 30 of 102 nonepithelial ovarian tumors (29%), predominantly in Sertoli-Leydig cell tumors (26 of 43, or 60%), including 4 tumors with additional germline DICER1 mutations. These mutations were restricted to codons encoding metal-binding sites within the RNase IIIb catalytic centers, which are critical for microRNA interaction and cleavage, and were somatic in all 16 samples in which germline DNA was available for testing. We also detected mutations in 1 of 14 nonseminomatous testicular germ-cell tumors, in 2 of 5 embryonal rhabdomyosarcomas, and in 1 of 266 epithelial ovarian and endometrial carcinomas. The mutant DICER1 proteins had reduced RNase IIIb activity but retained RNase IIIa activity.
CONCLUSIONS
Somatic missense mutations affecting the RNase IIIb domain of DICER1 are common in nonepithelial ovarian tumors. These mutations do not obliterate DICER1 function but alter it in specific cell types, a novel mechanism through which perturbation of microRNA processing may be oncogenic.

AB The field of stem-cell biology has been catapulted forward by the startling development of reprogramming technology. The ability to restore pluripotency to somatic cells through the ectopic co-expression of reprogramming factors has created powerful new opportunities for modelling human diseases and offers hope for personalized regenerative cell therapies. While the field is racing ahead, some researchers are pausing to evaluate whether induced pluripotent stem cells are indeed the true equivalents of embryonic stem cells and whether subtle differences between these types of cell might affect their research applications and therapeutic potential.

AB Retinoblastoma is an aggressive childhood cancer of the developing retina that is initiated by the biallelic loss of RB1. Tumours progress very quickly following RB1 inactivation but the underlying mechanism is not known. Here we show that the retinoblastoma genome is stable, but that multiple cancer pathways can be epigenetically deregulated. To identify the mutations that cooperate with RB1 loss, we performed whole-genome sequencing of retinoblastomas. The overall mutational rate was very low; RB1 was the only known cancer gene mutated. We then evaluated the role of RB1 in genome stability and considered non-genetic mechanisms of cancer pathway deregulation. For example, the proto-oncogene SYK is upregulated in retinoblastoma and is required for tumour cell survival. Targeting SYK with a small-molecule inhibitor induced retinoblastoma tumour cell death in vitro and in vivo. Thus, retinoblastomas may develop quickly as a result of the epigenetic deregulation of key cancer pathways as a direct or indirect result of RB1 loss.

AB Acetyl coenzyme A (AcCoA) is the central biosynthetic precursor for fatty-acid synthesis and protein acetylation. In the conventional view of mammalian cell metabolism, AcCoA is primarily generated from glucose-derived pyruvate through the citrate shuttle and ATP citrate lyase in the cytosol(1-3). However, proliferating cells that exhibit aerobic glycolysis and those exposed to hypoxia convert glucose to lactate at near-stoichiometric levels, directing glucose carbon away from the tricarboxylic acid cycle and fatty-acid synthesis(4). Although glutamine is consumed at levels exceeding that required for nitrogen biosynthesis(5), the regulation and use of glutamine metabolism in hypoxic cells is not well understood. Here we show that human cells use reductive metabolism of alpha-ketoglutarate to synthesize AcCoA for lipid synthesis. This isocitrate dehydrogenase-1 (IDH1)-dependent pathway is active in most cell lines under normal culture conditions, but cells grown under hypoxia rely almost exclusively on the reductive carboxylation of glutamine-derived alpha-ketoglutarate for de novo lipogenesis. Furthermore, renal cell lines deficient in the von Hippel-Lindau tumour suppressor protein preferentially use reductive glutamine metabolism for lipid biosynthesis even at normal oxygen levels. These results identify a critical role for oxygen in regulating carbon use to produce AcCoA and support lipid synthesis in mammalian cells.

AB A major challenge for the treatment of many central nervous system (CNS) disorders is the lack of convenient and effective methods for delivering biological agents to the brain. Mucopolysaccharidosis II (Hunter syndrome) is a rare inherited lysosomal storage disorder resulting from a deficiency of iduronate-2-sulfatase (I2S). I2S is a large, highly glycosylated enzyme. Intravenous administration is not likely to be an effective therapy for disease-related neurological outcomes that require enzyme access to the brain cells, in particular neurons and oligodendrocytes. We demonstrate that intracerebroventricular and lumbar intrathecal administration of recombinant I2S in dogs and nonhuman primates resulted in widespread enzyme distribution in the brain parenchyma, including remarkable deposition in the lysosomes of both neurons and oligodendrocytes. Lumbar intrathecal administration also resulted in enzyme delivery to the spinal cord, whereas little enzyme was detected there after intraventricular administration. Mucopolysaccharidosis II model is available in mice. Lumbar administration of recombinant I2S to enzyme deficient animals reduced the storage of glycosaminoglycans in both superficial and deep brain tissues, with concurrent morphological improvements. The observed patterns of enzyme transport from cerebrospinal fluid to the CNS tissues and the resultant biological activity (a) warrant further investigation of intrathecal delivery of I2S via lumbar catheter as an experimental treatment for the neurological symptoms of Hunter syndrome and (b) may have broader implications for CNS treatment with biopharmaceuticals.

AB The endothelial-specific Angiopoietin-Tie2 ligand-receptor system is an important regulator of endothelial activation. Binding of angiopoietin-2 (Ang-2) to Tie2 receptor renders the endothelial barrier responsive to pro-inflammatory cytokines. We previously showed that circulating Ang-2 correlated with disease severity in a small cohort of critically ill patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis. The current study reassessed Ang-2 as a biomarker of disease activity and relapse in AAV. Circulating Ang-2 was measured in 162 patients with severe AAV (BVAS/WG >= 3, with or without glomerulonephritis) in a clinical trial. Ang-2 levels during active AAV were compared to levels in the same patients during remission (BVAS/WG = 0). Levels in clinical subsets of AAV were compared, and association with future disease course was assessed. Ang-2 levels were elevated in severe disease (median 3.0 ng/ml, interquartile range 1.9-4.4) compared to healthy controls (1.2, 0.9-1.5). However, they did not reliably decline with successful treatment (median 2.6 ng/ml, interquartile range 1.9-3.8, median change -0.1). Ang-2 correlated weakly with BVAS/WG score (r = 0.17), moderately with markers of systemic inflammation (r = 0.25-0.41), and inversely with renal function (r = -0.36). Levels were higher in patients with glomerulonephritis, but levels adjusted for renal dysfunction were no different in patients with or without glomerulonephritis. Levels were higher in patients with newly diagnosed AAV and lower in patients in whom treatment had recently been started. Ang-2 levels during active disease did not predict response to treatment, and Ang-2 levels in remission did not predict time to flare. Thus, Ang-2 appears to have limited practical value in AAV as a biomarker of disease activity at time of measurement or for predicting future activity.

AB In non-cancerous cells, phosphorylated proteins exist transiently, becoming de-phosphorylated by specific phosphatases that terminate propagation of signaling pathways. In cancers, compromised phosphatase activity and/or expression occur and contribute to tumor phenotype. The non-receptor phosphatase, PTPN13, has recently been dubbed a putative tumor suppressor. It decreased expression in breast cancer correlates with decreased overall survival. Here we show that PTPN13 regulates a new signaling complex in breast cancer consisting of ErbB2, Src, and EphrinB1. To our knowledge, this signaling complex has not been previously described. Co-immunoprecipitation and localization studies demonstrate that EphrinB1, a PTPN13 substrate, interacts with ErbB2. In addition, the oncogenic V660E ErbB2 mutation enhances this interaction, while Src kinase mediates EphrinB1 phosphorylation and subsequent MAP Kinase signaling. Decreased PTPN13 function further enhances signaling. The association of oncogene kinases (ErbB2, Src), a signaling transmembrane ligand (EphrinB1) and a phosphatase tumor suppressor (PTPN13) suggest that EphrinB1 may be a relevant therapeutic target in breast cancers harboring ErbB2-activating mutations and decreased PTPN13 expression.

A subpopulation of ALS patients possesses higher levels of resting energy expenditure and lower fat-free mass compared to healthy controls. Similarly, two mutant copper zinc superoxide dismutase 1 (mSOD1) mouse models of familial ALS possess a hypermetabolic phenotype. The pathophysiological relevance of the bioenergetic defects observed in ALS remains largely elusive. AMP-activated protein kinase (AMPK) is a key sensor of cellular energy status and thus might be activated in various models of ALS. Here, we report that AMPK activity is increased in spinal cord cultures expressing mSOD1, as well as in spinal cord lysates from mSOD1 mice. Reducing AMPK activity either pharmacologically or genetically prevents mSOD1-induced motor neuron death in vitro. To investigate the role of AMPK in vivo, we used Caenorhabditis elegans models of motor neuron disease. C. elegans engineered to express human mSOD1(G85R) in neurons develops locomotor dysfunction and severe fecundity defects when compared to transgenic worms expressing human wild-type SOD1. Genetic reduction of aak-2, the ortholog of the AMPK alpha 2 catalytic subunit in nematodes, improved locomotor behavior and fecundity in G85R animals. Similar observations were made with nematodes engineered to express mutant tat-activating regulatory (TAR) DNA-binding protein of 43 kDa molecular weight. Altogether, these data suggest that bioenergetic abnormalities are likely to be pathophysiologically relevant to motor neuron disease.

TI Skin Effector Memory T Cells Do Not Recirculate and Provide Immune

AB Cutaneous T cell lymphoma (CTCL) is a cancer of skin-homing T cells with variants that include leukemic CTCL (L-CTCL), a malignancy of central memory T cells (T(CM)), and mycosis fungoides (MF), a malignancy of skin resident effector memory T cells (T(EM)). We report that low-dose alemtuzumab (alpha CD52) effectively treated patients with refractory L-CTCL but not MF. Alemtuzumab depleted all T cells in blood and depleted both benign and malignant T(CM) from skin, but a diverse population of skin resident T(EM) remained in skin after therapy. T cell depletion with alemtuzumab required the presence of neutrophils, a cell type frequent in blood but rare in normal skin. These data suggest that T(CM) were depleted because they recirculate between the blood and the skin, whereas skin resident T(EM) were spared because they are sessile and non-recirculating. After alemtuzumab treatment, skin T cells produced lower amounts of interleukin-4 and higher amounts of interferon-gamma. Moreover, there was a marked lack of infections in alemtuzumab-treated L-CTCL patients despite the complete absence of T cells in the blood, suggesting that skin resident T(EM) can protect the skin from pathogens even in the absence of T cell recruitment from the circulation. Together, these data suggest that alemtuzumab may treat refractory L-CTCL without severely compromising the immune response to infection by depleting circulating T(CM) but sparing the skin resident T(EM) that provide local immune protection of the skin.

TI Evaluation of rapid point-of-care creatinine testing in the radiology
service of a large academic medical center: Impact on clinical
operations and patient disposition
SO CLINICA CHIMICA ACTA
LA English
DT Article
DE Point-of-care testing; Creatinine; Outcomes; Contrast induced
nephropathy; Nephrogenic systemic fibrosis
ID EMERGENCY-DEPARTMENT; IMPLEMENTATION; STAY
AB Background: Measurement of creatinine and calculation of the estimated glomerular filtration rate (eGFR) are widely employed to identify patients with chronic kidney disease who are at risk for contrast induced acute kidney injury and nephrogenic systemic fibrosis. However, patients may present for radiologic studies without a recent creatinine/eGFR necessitating cancelation of the study or performance of the scan without contrast. Both of these approaches are suboptimal.
Methods: We implemented a rapid whole blood point-of-care (POCT) creatinine test (iSTAT, Abbott Point-of-Care) in our radiology department and assessed the impact on clinical operations.
Results: Over a 7-month period a total of 3087 creatinine tests were performed. Overall 53% of patients presenting for scans (441/month) did not have a recent eGFR. An audit of 1 month of creatinine/eGFR values showed that 74% were normal permitting the scan to be performed without further consideration. Of the abnormal values 74% were performed with contrast and 26% without. Of note 78% of patients with an abnormal eGFR had a normal creatinine value. The cost of the POC test was $10.06 compared to a cost of $5.32 (including phlebotomy) for a creatinine performed in the central laboratory. The added incremental cost for the POC test was therefore $4.74.
Conclusions: Determining the cost effectiveness of the rapid test is extremely challenging because the analysis would need to take many complex factors into consideration including the effect on workflow in the radiology department, the clinical impact of more timely scans, the clinical and financial consequences of performing scans with or without contrast and the impact on revenues complicated by differential reimbursement rates and payor mix. However, given the benefits of the test on radiology operations and on the quality and timeliness of care it appears that the POCT test is cost effective and improves clinical operations.

AB Background: Protein domains are the structural, functional and evolutionary units of the protein. Protein domain architectures are the linear arrangements of domain(s) in individual proteins. Although the evolutionary history of protein domain architecture has been extensively studied in microorganisms, the evolutionary dynamics of domain architecture in the plant kingdom remains largely undefined. To address this question, we analyzed the lineage-based protein domain architecture content in 14 completed green plant genomes.
Results: Our analyses show that all 14 plant genomes maintain similar distributions of species-specific, single-domain, and multi-domain architectures. Approximately 65% of plant domain architectures are universally present in all plant lineages, while the remaining architectures are lineage-specific. Clear examples are seen of both the loss and gain of specific protein architectures in higher plants. There has been a dynamic, lineage-wise expansion of domain architectures during plant evolution. The data suggest that this expansion can be largely explained by changes in nuclear ploidy resulting from rounds of whole genome duplications. Indeed, there has been a decrease in the number of unique domain architectures when the genomes were normalized into a presumed ancestral genome that has not undergone whole genome duplications.
Conclusions: Our data show the conservation of universal domain architectures in all available plant genomes, indicating the presence of an evolutionarily conserved, core set of protein components. However, the occurrence of lineage-specific domain architectures indicates that domain architecture diversity has been maintained beyond these core components in plant genomes. Although several features of genome-wide domain architecture content are conserved in plants, the data clearly demonstrate lineage-wise, progressive changes and expansions of individual protein domain architectures, reinforcing the notion that plant genomes have undergone dynamic evolution.

AB Background: RNA from exosomes and other microvesicles contain transcripts of tumour origin. In this study we sought to identify biomarkers of glioblastoma multiforme in microvesicle RNA from serum of affected patients.
Methods: Microvesicle RNA from serum from patients with de-novo primary glioblastoma multiforme (N = 9) and normal controls (N = 7) were analyzed by microarray analysis. Samples were collected according to protocols approved by the Institutional Review Board. Differential expressions were validated by qRT-PCR in a separate set of samples (N = 10 in both groups).
Results: Expression profiles of microvesicle RNA correctly separated individuals in two groups by unsupervised clustering. The most significant differences pertained to down-regulated genes (121 genes > 2-fold down) in the glioblastoma multiforme patient microvesicle RNA, validated by qRT-PCR on several genes. Overall, yields of microvesicle RNA from patients was higher than from normal controls, but the additional RNA was primarily of size < 500 nt. Gene ontology of the down-regulated genes indicated these are coding for ribosomal proteins and genes related to ribosome production.
Conclusions: Serum microvesicle RNA from patients with glioblastoma multiforme has significantly down-regulated levels of RNAs coding for ribosome production, compared to normal healthy controls, but a large overabundance of RNA of unknown origin with size < 500 nt.

AB With the fast advancement in the genetics and bio-medical fields, the vast number of valuable transgenic and rare genetic mouse models need to be preserved. Preservation of mouse sperm by convective drying and subsequent storing at above freezing temperatures could dramatically reduce the cost and facilitate shipping. Mouse sperm were convectively dried under nitrogen gas in the Na-EGTA solution containing 100 mmol/L 3-O-methyl-D-glucose and stored in LiCl sorption jars (Relative Humidity, RH, 12%) at 4 degrees C and 22 degrees C for up to one year. The functionality of these sperm samples after storage was tested by intracytoplasmic injection into mouse oocytes. The percentages of blastocysts produced from sperm stored at 4 degrees C for 1, 2, 3, 6, and 12 months were 62.6%, 53.4%, 39.6%, 33.3%, and 30.4%, respectively, while those stored at 22 degrees C for 1, 2, and 3 months were 28.8%, 26.6%, and 12.2%, respectively. Transfer of 38 two-to four-cell embryos from sperm stored at 4 degrees C for 1 year produced two live pups while 59 two-to four-cell embryos from sperm stored at 22 degrees C for 3 months also produced two live pups. Although all the pups looked healthy at 3 weeks of age, normality of offspring produced using convectively dried sperm needs further investigation. The percentages of blastocyst from sperm stored in the higher relative humidity conditions of NaBr and MgCl2 jars and driest condition of P2O5 jars at 4 degrees C and 22 degrees C were all lower. A simple method of mouse sperm preservation is demonstrated. Three-O-methyl-D-glucose, a metabolically inactive derivative of glucose, offers significant protection for dried mouse sperm at above freezing temperatures without the need for poration of cell membrane.

AB Firefly luciferase is one of the few soluble proteins that is acted upon by a wide variety of general anesthetics and alcohols; they inhibit the ATP-driven production of light. We have used time-resolved photolabeling to locate the binding sites of alcohols during the initial light output, some 200 ms after adding ATP. The photolabel 3-azioctanol inhibited the initial light output with an IC50 of 200 mu M, close to its general anesthetic potency. Photoincorporation of [H-3]3-azioctanol into luciferase was saturable but weak. It was enhanced 200 ms after adding ATP but was negligible minutes later. Sequencing of tryptic digests by HPLC-MSMS revealed a similar conformation-dependence for photoincorporation of 3-azioctanol into Glu-313, a residue that lines the bottom of a deep cleft (vestibule) whose outer end binds luciferin. An aromatic diazirine analog of benzyl alcohol with broader side chain reactivity reported two sites. First, it photolabeled two residues in the vestibule, Ser-286 and Ile-288, both of which are implicated with Glu-313 in the conformation change accompanying activation. Second, it photolabeled two residues that contact luciferin, Ser-316 and Ser-349. Thus, time resolved photolabeling supports two mechanisms of action. First, an allosteric one, in which anesthetics bind in the vestibule displacing water molecules that are thought to be involved in light output. Second, a competitive one, in which anesthetics bind isosterically with luciferin. This work provides structural evidence that supports the competitive and allosteric actions previously characterized by kinetic studies.

AB Identification of gene expression profiles of cancer stem cells may have significant implications in the understanding of tumor biology and for the design of novel treatments targeted toward these cells. Here we report a potential ovarian cancer stem cell gene expression profile from isolated side population of fresh ascites obtained from women with high-grade advanced stage papillary serous ovarian adenocarcinoma. Affymetrix U133 Plus 2.0 microarrays were used to interrogate the differentially expressed genes between side population (SP) and main population (MP), and the results were analyzed by paired T-test using BRB-ArrayTools. We identified 138 up-regulated and 302 down-regulated genes that were differentially expressed between all 10 SP/MP pairs. Microarray data was validated using qRT-PCR and17/19 (89.5%) genes showed robust correlations between microarray and qRT-PCR expression data. The Pathway Studio analysis identified several genes involved in cell survival, differentiation, proliferation, and apoptosis which are unique to SP cells and a mechanism for the activation of Notch signaling is identified. To validate these findings, we have identified and isolated SP cells enriched for cancer stem cells from human ovarian cancer cell lines. The SP populations were having a higher colony forming efficiency in comparison to its MP counterpart and also capable of sustained expansion and differentiation in to SP and MP phenotypes. 50,000 SP cells produced tumor in nude mice whereas the same number of MP cells failed to give any tumor at 8 weeks after injection. The SP cells demonstrated a dose dependent sensitivity to specific c-secretase inhibitors implicating the role of Notch signaling pathway in SP cell survival. Further the generated SP gene list was found to be enriched in recurrent ovarian cancer tumors.

AB Secreted Gaussia luciferase (Gluc) has been shown to be a useful tool for ex vivo monitoring of in vivo biological processes. The Gluc level in the blood was used to detect tumor growth, metastasis and response to therapy, gene transfer, and circulating cells viability, as well as transcription factors activation, complementing in vivo bioluminescence imaging. The sensitivity of the Gluc blood assay is limited due to the absorption of blue light by pigmented molecules such as hemoglobin, resulting in quenching of the signal and therefore lower sensitivity. To overcome this problem, we designed an alternative microtiter well-based binding assay in which Gluc is captured first from blood using a specific antibody followed by the addition of coelenterazine and signal acquisition using a luminometer. This assay showed to be over 1 order of magnitude more sensitive in detecting Gluc in the blood as compared to the direct Gluc blood assay enhancing ex vivo monitoring of biological processes.

AB While target-based small-molecule discovery has taken centre-stage in the pharmaceutical industry, there are many cancer-promoting proteins not easily addressed with a traditional target-based screening approach. In order to address this problem, as well as to identify modulators of biological states in the absence of knowing the protein target of the state switch, alternative phenotypic screening approaches, such as gene expression-based and high-content imaging, have been developed. With this renewed interest in phenotypic screening, however, comes the challenge of identifying the binding protein target(s) of small-molecule hits. Emerging technologies have the potential to improve the process of target identification. In this review, we discuss the application of genomic (gene expression-based), genetic (short hairpin RNA and open reading frame screening), and proteomic approaches to protein target identification.

AB In eukaryotic organisms, the largely cytosolic copper- and zinc-containing superoxide dismutase (Cu/Zn SOD) enzyme represents a key defense against reactive oxygen toxicity. Although much is known about the biology of this enzyme under aerobic conditions, less is understood regarding the effects of low oxygen levels on Cu/Zn SOD enzymes from diverse organisms. We show here that like bakers' yeast (Saccharomyces cerevisiae), adaptation of the multicellular Caenorhabditis elegans to growth at low oxygen levels involves strong downregulation of its Cu/Zn SOD. Much of this regulation occurs at the post-translational level where CCS-independent activation of Cu/Zn SOD is inhibited. Hypoxia inactivates the endogenous Cu/Zn SOD of C. elegans Cu/Zn SOD as well as a P144 mutant of S. cerevisiae Cu/Zn SOD (herein denoted Sod1p) that is independent of CCS. In our studies of S. cerevisiae Sod1p, we noted a posttranslational modification to the inactive enzyme during hypoxia. Analysis of this modification by mass spectrometry revealed phosphorylation at serine 38. Serine 38 represents a putative proline-directed kinase target site located on a solvent-exposed loop that is positioned at one end of the Sod1p beta-barrel, a region immediately adjacent to residues previously shown to influence CCS-dependent activation. Although phosphorylation of serine 38 is minimal when the Sod1p is abundantly active (e.g., high oxygen level), up to 50% of Sod1p can be phosphorylated when CCS activation of the enzyme is blocked, e.g., by hypoxia or low-copper conditions. Serine 38 phosphorylation can be a marker for inactive pools of Sod1p.

AB Esophageal adenocarcinoma (EAC) arises from Barrett esophagus (BE), intestinal-like columnar metaplasia linked to reflux esophagitis. In a transgenic mouse model of BE, esophageal overexpression of interleukin-1 beta phenocopies human pathology with evolution of esophagitis, Barrett-like metaplasia and EAC. Histopathology and gene signatures closely resembled human BE, with upregulation of TFF2, Bmp4, Cdx2, Notch1, and IL-6. The development of BE and EAC was accelerated by exposure to bile acids and/or nitrosamines, and inhibited by IL-6 deficiency. Lgr5(+) gastric cardia stem cells present in BE were able to lineage trace the early BE lesion. Our data suggest that BE and EAC arise from gastric progenitors due to a tumor-promoting IL-1 beta-IL-6 signaling cascade and DII1-dependent Notch signaling.

After adjustment for clinical cardiovascular risk predictors and left ventricular ejection fraction, elevated levels of MR-proANP, MR-proADM, and CT-proET-1 were independently associated with the risk of cardiovascular death or heart failure (hazard ratios per 1-SD increase in log-transformed biomarker levels of 1.97, 1.48, and 1.47, respectively; P <= 0.002 for each biomarker). These 3 biomarkers also significantly improved metrics of discrimination when added to a clinical model. Trandolapril significantly reduced the risk of cardiovascular death or heart failure in patients who had elevated levels of >= 2 biomarkers (hazard ratio, 0.53; 95% confidence interval, 0.36-0.80), whereas there was no benefit in patients with elevated levels of 0 or 1 biomarker (hazard ratio, 1.09; 95% confidence interval, 0.74-1.59; P(interaction) = 0.012).
Conclusions-In patients with stable coronary artery disease and preserved left ventricular ejection fraction, our results suggest that elevated levels of novel biomarkers of cardiovascular stress may help identify patients who are at higher risk of cardiovascular death and heart failure and may be useful to select patients who derive significant benefit from angiotensin-converting enzyme inhibitor therapy.
