ID PRIMARY INFANTILE GLAUCOMA; CHILDHOOD GLAUCOMA; UPDATE
AB Purpose: To describe a cohort of children with late-recognized primary congenital glaucoma (LRPCG), including age of presentation, age-related diagnostic signs, clinical abnormalities, and results of glaucoma surgery.
Methods: The medical records of 31 patients (49 eyes) with PCG recognized after 1 year of age were reviewed retrospectively. Patients were confirmed to have PCG based on their increased intraocular pressure (IOP), anterior segment abnormalities including findings on gonioscopy, and the absence of other causes of childhood glaucoma. The outcome of glaucoma surgery was reviewed and success measured by assessment of the relative control of IOP, occurrence of significant complications, and need for additional glaucoma surgery.
Results: Average age at diagnosis of glaucoma was 4.7 years (36% diagnosed at > 4 years of age). The most common initial diagnostic signs were corneal enlargement (46%, average age of 2.0 years), photophobia (20%, average age of 3.3 years), and suspected poor visual acuity (32%, average age of 9.9 years). Corneal cloudiness was not an initial sign for any patient. Haab's striae were present in 60% of the affected 49 eyes. Gonioscopy findings were abnormal in 82%, but the ciliary body band was seen in 81% and the scleral spur was visible in 47%. Sixty-one goniotomy procedures were performed for 39 eyes with overall success in 95% (37 eyes) and complete success in 65% (27 eyes). The final visual acuity was 20/200 or worse in 31% (15 eyes) and 20/40 or better in 60% (29 eyes).
Conclusions: An awareness of and familiarity with the subtle diagnostic signs of LRPCG can enable its differentiation from primary juvenile glaucoma and contribute to earlier recognition and treatment. Glaucoma surgery is often required for LRPCG and goniosurgery is the recommended initial procedure.

AB Objective: To determine the reliable perfusion parameters in dynamic contrast-enhanced MRI (DCE-MRI) for the monitoring antiangiogenic treatment in mice.
Materials and Methods: Mice, with U-118 MG tumor, were treated with either saline (n = 3) or antiangiogenic agent (sunitinib, n = 8). Before (day 0) and after (days 2, 8, 15, 25) treatment, DCE examinations using correlations of perfusion parameters (K-ep, K-el, and A(H) from two compartment model; time to peak, initial slope and % enhancement from time-intensity curve analysis) were evaluated.
Results: Tumor growth rate was found to be 129% +/- 28 in control group, -33% +/- 11 in four mice with sunitinib-treatment (tumor regression) and 47% +/- 15 in four with sunitinib-treatment (growth retardation). K-ep (r = 0.80) and initial slope (r = 0.84) showed strong positive correlation to the initial tumor volume (p < 0.05). In control mice, tumor regression group and growth retardation group animals, K-ep (r : 0.75, 0.78, 0.81, 0.69) and initial slope (r : 0.79, 0.65, 0.67, 0.84) showed significant correlation with tumor volume (p < 0.01). In four mice with tumor re-growth, K-ep and initial slope increased 20% or greater at earlier (n = 2) than or same periods (n = 2) to when the tumor started to re-grow with 20% or greater growth rate.
Conclusion: K-ep and initial slope may a reliable parameters for monitoring the response of antiangiogenic treatment.

AB Background. Previous study showed that hydroxyapatite nanoparticles (nano-HAPs) inhibited glioma growth in vitro and in vivo; and in a drug combination, they could reduce adverse reactions. We investigated the possible enhancement of radiosensitivity induced by nano-HAPs.
Methods. In vitro radiosensitization of nano-HAPs was measured using a clonogenic survival assay in human glioblastoma U251 and breast tumor brain metastatic tumor MDA-MB-231BR cells. DNA damage and repair were measured using gamma H2AX foci, and mitotic catastrophe was determined by immunostaining. The effect of nano-HAPs on in vivo tumor radiosensitivity was investigated in a subcutaneous and an orthotopic model.
Results. Nano-HAPs enhanced each cell line's radiosensitivity when the exposure was 1 h before irradiation, and they had no significant effect on irradiation-induced apoptosis or on the activation of the G(2) cell cycle checkpoint. The number of gamma H2AX foci per cell was significantly large at 24 h after the combination modality of nano-HAPs + irradiation compared with single treatments. Mitotic catastrophe was also significantly increased at an interval of 72 h in tumor cells receiving the combined modality compared with the individual treatments. In a subcutaneous model, nano-HAPs caused a larger than additive increase in tumor growth delay. In an orthotopic model, nano-HAPs significantly reduced tumor growth and extended the prolongation of survival induced by irradiation.
Conclusions. These results show that nano-HAPs can enhance the radiosensitivity of tumor cells in vitro and in vivo through the inhibition of DNA repair, resulting in an increase in mitotic catastrophe.

ID DNA MISMATCH REPAIR; TUMOR PROGRESSION; MALIGNANT GLIOMA; II TRIAL;
RESISTANCE; SCHEDULES; THERAPY; MSH6
AB Background. Among patients with glioblastoma (GBM) who progress on standard temozolomide, the optimal therapy is unknown. Resistance to temozolomide is partially mediated by O-6-methylguanine-DNA methyltransferase (MGMT). Because MGMT may be depleted by prolonged temozolomide administration, dose-intense schedules may overcome resistance.
Methods. This was a multicenter, phase 2, single-arm study of temozolomide (75-100 mg/m(2)/day) for 21 days of each 28-day cycle. Patients had GBM in first recurrence after standard therapy. The primary end point was 6-month progression-free survival (PFS6).
Results. Fifty-eight participants were accrued, 3 of whom were ineligible for analysis; one withdrew before response assessment. There were 33 men (61%), with a median age of 57 years (range, 25-79 years) and a median Karnofsky performance score of 90 (range, 60100). Of 47 patients with MGMT methylation results, 36 (65%) had methylated tumors. There were 7 (13%) partial responses, and PFS6 was only 11%. Response and PFS did not depend on MGMT status; MSH2, MLH1, or ERCC1 expression; the number of prior temozolomide cycles; or the time off temozolomide. Treatment was well tolerated, with limited grade 3 neutropenia (n = 2) or thrombocytopenia (n = 2).
Conclusions. Dose-intense temozolomide on this schedule is safe in recurrent GBM. However, efficacy is marginal and predictive biomarkers are needed.

AB Background. The prognosis for patients with recurrent glioblastoma remains poor. The purpose of this study was to assess the potential role of MR spectroscopy as an early indicator of response to anti-angiogenic therapy.
Methods. Thirteen patients with recurrent glioblastoma were enrolled in RTOG 0625/ACRIN 6677, a prospective multicenter trial in which bevacizumab was used in combination with either temozolomide or irinotecan. Patients were scanned prior to treatment and at specific timepoints during the treatment regimen. Postcontrast T1-weighted MRI was used to assess 6-month progression-free survival. Spectra from the enhancing tumor and peritumoral regions were defined on the postcontrast T1-weighted images. Changes in the concentration ratios of N-acetylaspartate/creatine (NAA/Cr), choline-containing compounds (Cho)/Cr, and NAA/Cho were quantified in comparison with pretreatment values.
Results. NAA/Cho levels increased and Cho/Cr levels decreased within enhancing tumor at 2 weeks relative to pretreatment levels (P = .048 and P = .016, respectively), suggesting a possible antitumor effect of bevacizumab with cytotoxic chemotherapy. Nine of the 13 patients were alive and progression free at 6 months. Analysis of receiver operating characteristic curves for NAA/Cho changes in tumor at 8 weeks revealed higher levels in patients progression free at 6 months (area under the curve = 0.85), suggesting that NAA/Cho is associated with treatment response. Similar results were observed for receiver operating characteristic curve analyses against 1-year survival. In addition, decreased Cho/Cr and increased NAA/Cr and NAA/Cho in tumor periphery at 16 weeks posttreatment were associated with both 6-month progression-free survival and 1-year survival.
Conclusion. Changes in NAA and Cho by MR spectroscopy may potentially be useful as imaging biomarkers in assessing response to anti-angiogenic treatment.

AB Background. RTOG 0625/ACRIN 6677 is a multicenter, randomized, phase II trial of bevacizumab with irinotecan or temozolomide in recurrent glioblastoma (GBM). This study investigated whether early posttreatment progression on FLAIR or postcontrast MRI assessed by central reading predicts overall survival (OS).
Methods. Of 123 enrolled patients, 107 had baseline and at least 1 posttreatment MRI. Two central neuroradiologists serially measured bidimensional (2D) and volumetric (3D) enhancement on postcontrast T1-weighted images and volume of FLAIR hyperintensity. Progression status on all posttreatment MRIs was determined using Macdonald and RANO imaging threshold criteria, with a third neuroradiologist adjudicating discrepancies of both progression occurrence and timing. For each MRI pulse sequence, Kaplan-Meier survival estimates and log-rank test were used to compare OS between cases with or without radiologic progression.
Results. Radiologic progression occurred after 2 chemotherapy cycles (8 weeks) in 9 of 97 (9%), 9 of 73 (12%), and 11 of 98 (11%) 2D-T1, 3D-T1, and FLAIR cases, respectively, and 34 of 80 (43%), 21 of 58 (36%), and 37 of 79 (47%) corresponding cases after 4 cycles (16 weeks). Median OS among patients progressing at 8 or 16 weeks was significantly less than that among nonprogressors, as determined on 2D-T1 (114 vs 278 days and 214 vs 426 days, respectively; P < .0001 for both) and 3D-T1 (117 vs 306 days [P < .0001] and 223 vs 448 days [P = .0003], respectively) but not on FLAIR (201 vs 276 days [P = .38] and 303 vs 321 days [P = .13], respectively).
Conclusion. Early progression on 2D-T1 and 3D-T1, but not FLAIR MRI, after 8 and 16 weeks of anti-vascular endothelial growth factor therapy has highly significant prognostic value for OS in recurrent GBM.

AB Background. Patients presenting with synchronous bifocal intracranial tumors (masses in the pineal and neurohypophyseal region), detectable human chorionic gonadotropin (hCG) levels (5-100 mIU/mL), and normal alpha feto-protein (AFP) levels (<= 10 ng/mL) are often diagnosed empirically with pure germinoma. In such scenarios, pathologic confirmation is often deferred, given that bifocal nongerminomatous germ cell tumors (NGGCTs) are considered rare and because available literature and research protocols support such an approach. Wesought to characterize the association between bifocal intracranial tumors and NGGCT histology.
Methods. Seventy-one patients treated for intracranial germ cell tumors at Massachusetts General Hospital in 1998-2012 were identified. Patients presenting with synchronous bifocal disease were selected for further review.
Results. Of the 71 patients presenting with intracranial germ cell tumors, 14 (19.7%) had synchronous bifocal disease. Of these 14 patients, 7 (50.0%) had germinoma, 3 (21.4%) had NGGCT, and 4 (28.6%) had hCG levels <200 mIU/mL and normal AFP levels and were treated without pathologic confirmation. Of the 3 patients with confirmed bifocal NGGCT, 2 had detectable hCG levels with AFP <10 ng/mL and 1 patient had a detectable hCG level with a modest elevation in AFP.
Conclusions. NGGCTs should be considered in the differential diagnosis for patients presenting with bifocal intracranial tumors. Given differences in the management of germinomas and NGGCTs, clinicians should strongly consider a biopsy in patients presenting with bifocal masses and normal or modestly elevated biomarkers. Misclassification of such cases as germinomas could result in undertreatment and a possible increased risk for recurrence.

AB Background: Metabolic syndrome (MetS)-a cluster of cardiovascular risk factors-is linked with cognitive decline and dementia. However, the brain changes underlying this link are presently unknown. In this study, we tested the relationship between MetS, cerebral blood flow (CBF), white matter hyperintensity burden, and gray matter (GM) volume in cognitively healthy late middle-aged adults. Additionally, the extent to which MetS was associated with cognitive performance was assessed.
Design and Methods: Late middle-aged adults from the Wisconsin Registry for Alzheimer's Prevention (N = 69, mean age = 60.4 years) underwent a fasting blood draw, arterial spin labeling perfusion MRI, T1-weighted MRI, T2FLAIR MRI, and neuropsychological testing. MetS was defined as abnormalities on three or more factors, including abdominal obesity, triglycerides, HDL-cholesterol, blood pressure, and fasting glucose.
Results: Mean GM CBF was 15% lower in MetS compared to controls. Voxel-wise image analysis indicated that the MetS group had lower CBF across a large portion of the cortical surface, with the exception of medial and inferior parts of the occipital and temporal lobes. The MetS group also had lower immediate memory function; a mediation analysis indicated this relationship was partially mediated by CBF. Among the MetS factors, abdominal obesity and elevated triglycerides were most strongly associated with lower CBF.
Conclusions: The results underscore the importance of reducing the number of cardiovascular risk factors for maintaining CBF and cognition in an aging population.

AB Objective: Obesity has been associated with cognitive decline in longitudinal studies of older individuals. We hypothesized that the cognitive sequelae of obesity may be detectable in the reproductive years. In addition, we explored the hypothesis that these associations may be mediated by the hormonal milieu.
Design and Methods: Of 49 young healthy lean and overweight women aged 20-45, we investigated the association between performance on a battery of cognitive tests, body composition parameters [body mass index, total fat, abdominal (visceral, subcutaneous, and total) adipose tissue, and muscle], and hormone levels (insulin, adiponectin, leptin, insulin-like growth factor 1 (IGF-1), estrogen, testosterone, and vitamin D).
Results: We found a significant negative association between both visceral adiposity and muscle, and performance in the domain of verbal learning and memory, after controlling for age and education. Other body composition parameters showed similar trends (0.05 < P < 0.10). Additionally, the degree of insulin resistance was negatively associated with executive function domain. None of the associations between the other hormones examined (adipokines, IGF-1, gonadal hormones, and vitamin D) and cognitive function were significant.
Conclusion: These preliminary findings suggest a possible association between obesity and cognitive function in healthy young women of reproductive age. More research is warranted into the potential modulatory effect of insulin resistance on this association.

AB Objective: To examine associations of perinatal and 3-year leptin with weight gain and adiposity through 7 years.
Design and Methods: In Project Viva, plasma leptin from mothers at 26-28 weeks' gestation (n = 893), umbilical cord vein at delivery (n = 540), and children at 3 years (n = 510) was assessed in relation to BMI z-score, waist circumference, skinfold thicknesses, and dual X-ray absorptiometry body fat.
Results: 50.1% of children were male and 29.5% non-white. Mean (SD) maternal, cord, and age 3 leptin concentrations were 22.9 (14.2), 8.8 (6.4), and 1.8 (1.7) ng/ml, respectively, and 3- and 7-year BMI z-scores were 0.46 (1.00) and 0.35 (0.97), respectively. After adjusting for parental and child characteristics, higher maternal and cord leptin were associated with less 3- year adiposity. For example, mean 3- year BMI z-score was 0.5 lower (95% CI: -0.7, -0.2; P-trend = 0.003) among children whose mothers' leptin concentrations were in the top versus bottom quintile. In contrast, higher age 3 leptin was associated with greater weight gain and adiposity through age 7 [e.g., change in BMI z-score from 3 to 7 years was 0.2 units (95% CI: -0.0, 0.4; P-trend =0.05)].
Conclusion: Higher perinatal leptin was associated with lower 3- year adiposity, whereas higher age 3 leptin was associated with greater weight gain and adiposity by 7 years.

AB Objective: Perivascular fat may have a local adverse effect on the vasculature. We evaluated whether thoracic periaortic adipose tissue (TAT), a type of perivascular fat, and visceral adipose tissue (VAT) were associated with vascular function.
Design and Methods: TAT and VAT were quantified in Framingham Heart Study participants using multidetector-computed tomography; vascular function was assessed using brachial artery vasodilator function, peripheral arterial tone, and arterial tonometry (n = 2,735; 48% women; mean age, 50 years; mean body mass index [BMI], 27.7 kg/m(2)). Using multiple linear regression, the relationships between TAT, VAT, and vascular measures was examined while adjusting for cardiovascular risk factors.
Results: Mean TAT and VAT volumes were 13.2 and 1763 cm(3). TAT and VAT were associated with multiple vascular function measures after multivariable adjustment. After BMI adjustment, TAT and VAT remained negatively associated with peripheral arterial tone and inverse carotid femoral pulse wave velocity (P < 0.02); TAT was negatively associated with hyperemic mean flow velocity (P = 0.03). Associations of TAT with vascular function were attenuated after VAT adjustment (all P > 0.06).
Conclusions: Thoracic periaortic and visceral fat are associated with microvascular function and large artery stiffness after BMI adjustment. These findings support the growing recognition of associations between ectopic fat and vascular function.

AB There is no clear consensus on how to manage a subset of patients with prostate cancer (PCa) who present with involved lymph nodes (LN+). Although outcomes for these patients are uniformly worse than those for patients with localized PCa, they are better than outcomes for patients with bone metastases, with more than 60% of patients alive at 10 years after the initial diagnosis. This article reviews the existing data on outcomes for patients treated with various combinations of systemic and local therapies. Current evidence suggests both a disease-control benefit and a survival benefit to multi-modality therapy, which combines systemic androgen deprivation therapy (ADT) with local therapies, such as surgery and radiation, without evidence of excessive treatment-related toxicities.

AB A growing understanding of the biology and molecular mechanisms of melanoma has led to the identification of a number of driver mutations for this aggressive tumor. The most common mutations affect signaling of the Ras/Raf/MAPK (mitogen-activated protein kinase) pathway. This review will focus on mutations in genes encoding proteins that play a role in the MAPK pathway and that have been implicated in melanoma biology, such as BRAF, NRAS, and MEK (MAPK kinase), and detail the current understanding of their role in melanoma progression from a molecular biology perspective. Furthermore, this review will also consider some additional mutations in genes such as KIT, GNAQ, and GNA11, which can be seen in certain subtypes of melanoma and whose gene products interact with the MAPK pathway. In addition, the association of these molecular changes with clinical and classical histopathologic characteristics of melanoma will be outlined and their role in diagnosis of melanocytic lesions discussed. Finally, a basic overview of the current targeted therapy landscape, as far as relevant to the pathologist, will be provided.

Methods: Retrospective expenditure data were collected from Medicare records. Beneficiaries with diabetes were grouped into 5 consumption clusters ranging from "crisis consumers" at the high end to "low consumers" at the low end.
Results: The percentages of beneficiaries and expenditures for the consumption clusters remained generally constant from year to year. As expected, most of Medicare's budget each year was spent on crisis, heavy, and moderate consumers. However, a notable proportion of low and light consumers from one year go on to become crisis and heavy consumers in subsequent years. A review of total 2001 through 2006 inpatient costs for the year 2000 clusters revealed that 47% of these costs were for year 2000 low and light consumers and only 27% were for year 2000 crisis and heavy consumers.
Conclusions: This analysis revealed previously unrecognized trends, whereby a notable proportion of low and light consumers during one year went on to become crisis and heavy consumers in subsequent years, representing a large proportion of inpatient costs. These findings have important implications for disease management programs, which typically focus intervention efforts exclusively on crisis and heavy consumers.

AB Objectives: To evaluate the impact on smoking status documentation of a payer-sponsored pay-for-performance (P4P) incentive that targeted a minority of an integrated healthcare delivery system's patients.
Study Design: Three commercial insurers simultaneously adopted P4P incentives to document smoking status of their members with 3 chronic diseases. The healthcare system responded by adding a smoking status reminder to all patients' electronic health records (EHRs). We measured change in smoking status documentation before (2008-2009) and after (2010-2011) P4P implementation by patient P4P eligibility.
Methods: The P4P-eligible patients were compared primarily with a subset of non P4P-eligible patients who resembled P4P-eligible patients and also with all non-P4P-eligible patients. Multivariate models adjusted for patient and provider characteristics and accounted for provider-level clustering and preimplementation trends.
Results: Documentation increased from 48% of 207,471 patients before P4P to 71% of 227,574 patients after P4P. Improvement from 56% to 83% occurred among P4P-eligible patients (adjusted odds ratio [AOR], 3.6; 95% confidence interval [CI], 2.9-4.5) and from 56% to 80% among the comparable subset of non P4P-eligible patients (AOR, 3.0; 95% CI, 2.3-3.9). The difference in improvement between groups was significant (AOR, 1.3; 95% CI, 1.1-1.4; P = .009).
Conclusions: A P4P incentive targeting a minority of a healthcare system's patients stimulated adoption of a systemwide EHR reminder and improved smoking status documentation overall. Combining a P4P incentive with an EHR reminder might help healthcare systems improve treatment delivery for smokers and meet "meaningful use" standards for EHRs.

TI The Patient-Centered Medical Home in the Veterans Health Administration
SO AMERICAN JOURNAL OF MANAGED CARE
LA English
DT Article
ID PRIMARY-CARE; TRANSFORMATION; MODEL; COST
AB Background:The Veterans Health Administration (VHA) is the largest integrated US health system to implement the patient-centered medical home. The Patient Aligned CareTeam (PACT) initiative (implemented 2010-20141 aims to achieve team-based care, improved access, and care management for more than 5 million primary care patients nationwide.
Objectives: To describe PACT and evaluate interim changes in PACT-related care processes.
Study Design: Data from the VHA Corporate Data Warehouse were obtained from April 2009 (pre-PACT) to September 2012. All patients assigned to a primary care provider (PCP) at all VHA facilities were included.
Methods: Nonparametric tests of trend across time points.
Results: VHA increased primary care staff levels from April 2010 to December 2011 (2.3 to 3.0 staff per PCP full-time equivalent). In-person PCP visit rates slightly decreased from April 2009 to April 2012 (53 to 43 per 100 patients per calendar quarter; P <.01), while in-person nurse encounter rates remained steady. Large increases were seen in phone encounters (2.7 to 28.8 per 100 patients per quarter; P <.01), enhanced personal health record use (3% to 13% of patients enrolled), and electronic messaging to providers (0.01% to 2.3% of patients per quarter). Post hospitalization follow-up improved (6.6% to 61% of VA hospital discharges), but home telemonitoring (0.8% to 1.4% of patients) and group visits (0.2 to 0.65 per 100 patients per quarter; P <.01) grew slowly.
Conclusions:Thirty months into PACT, primary care staff levels and phone and electronic encounters have greatly increased; other changes have been positive but slower.

AB Bone histomorphometry measurements require high spatial resolution that may not be feasible using multidetector CT (MDCT). This study evaluated the trabecular microarchitecture of lumbar spine using MDCT and C-arm CT in a series of young adult patients with anorexia nervosa (AN). 11 young females with AN underwent MDCT (anisotropic resolution with a slice thickness of similar to 626 mu m) and C-arm CT (isotropic resolution of 200 pm). Standard histomorphometric parameters the of L1 vertebral body, namely the apparent trabecular bone volume fraction (BV/TV), trabecular thickness (TbTh), trabecular number (TbN) and trabecular separation (TbSp), were analysed using MicroView software (GE Healthcare, Piscataway, NJ). Bone mineral density (BMD) was measured using dual-energy X-ray absorptiometry. Trabecular parameters derived from MDCT and C-arm CT were compared, and their association with F3MD parameters was evaluated. Histomorphonnetric parameters derived from C-arm CT, namely TbTh, TbN and TbSp, were significantly different from the corresponding MDCT parameters. There were no significant correlations between C-arm CT-derived parameters and the corresponding MDCT-derived parameters. C-arm CT-derived parameters were significantly (p<0.001) correlated with anteroposterior L1 spine BMD and Z-scores: TbTh (r=0.723, r=0.744, respectively), TbN.(r=-0.720, r=-0.712, respectively) and TbSp (r=0.656, r=0.648, respectively). BV/TV, derived from C-arm CT, was significantly associated with body mass index (r=0.636) and ideal body weight (r=0.730) (p<0.05). These associations were not present in MDCT-derived parameters. This study suggests that the spatial resolution offered by C-arm CT more accurately captures the histomorphometric parameters of trabecular morphology than MDCT in patients with AN.

AB Kupffer cells (KCs) are resident liver macrophages that play a crucial role in liver homeostasis and in the pathogenesis of liver disease. Evidence suggests KCs have both stimulatory and inhibitory functions during tumor development but the extent of these functions remains to be defined. Using KC depletion studies in an orthotopic murine model of colorectal cancer (CRC) liver metastases we demonstrated the bimodal role of KCs in determining tumor growth. KC depletion with gadolinium chloride before tumor induction was associated with an increased tumor burden during the exponential growth phase. In contrast, KC depletion at the late stage of tumor growth (day 18) decreased liver tumor load compared with non-depleted animals. This suggests KCs exhibit an early inhibitory and a later stimulatory effect. These two opposing functions were associated with changes in iNOS and VEGF expression as well as T-cell infiltration. KC depletion at day 18 increased numbers of CD3(+) T cells and iNOS-expressing infiltrating cells in the tumor, but decreased the number of VEGF-expressing infiltrating cells. These alterations may be responsible for the observed reduction in tumor burden following depletion of pro-tumor KCs at the late stage of metastatic growth. Taken together, our results indicate that the bimodal role of KC activity in liver tumors may provide the key to timing immunomodulatory intervention for the treatment of CRC liver metastases.

AB The transformation of colonic mucosal epithelium to adenocarcinoma requires progressive oncogene activation and tumor suppressor gene inactivation. Loss of chromosome 18q is common in colon cancer but not in precancerous adenomas. A few candidate tumor suppressor genes have been identified in this region, including CABLES1 at 18q11.2-12.1. This study investigates the role of CABLES1 in an in vivo mouse model of intestinal adenocarcinoma and in human colon cancer cell culture. Apc(Min/+) mice were crossed with mice harboring targeted inactivation of the Cables1 gene (Cables1(-/-)). The intestinal tumor burden and tumor expression of -catenin and PCNA was compared in Cables1(+/+)Apc(Min/+) and Cables1(-/-)Apc(Min/+) mice. -catenin activity in human colon cancer cells with CABLES1 inactivation and intestinal progenitor cell function in Cables1(-/-) mice were assayed in vitro. The mean number of small intestinal tumors per mouse was 3.1 +/- 0.6 in Cables1(+/+) Apc(Min/+) mice, compared with 32.4 +/- 3.5 in the Cables1(-/-)Apc(Min/+) mice (P < 0.0001). Fewer colonic tumors were observed in Cables1(+/+)Apc(Min/+) mice (mean 0.6 +/- 0.1) compared with the Cables1(-/-)Apc(Min/+) mice (mean 1.3 +/- 0.3, P = 0.01). Tumors from Cables1(-/-)Apc(Min/+) mice demonstrated increased nuclear expression of -catenin and an increased number of PCNA-positive cells. In vitro studies revealed that CABLES1 deficiency increased -catenin dependent transcription and increased intestinal progenitor cell activity. Loss of Cables1 enhances tumor progression in the Apc(Min/+) mouse model and activates the Wnt/-catenin signaling pathway. Cables1 is a tumor suppressor gene on chromosome 18q in this in vivo mouse model and likely has a similar role in human colon cancer.

AB Mouse p202 containing two hemopoietic expression, interferon inducibility, nuclear localization (HIN) domains antagonizes AIM2 inflammasome signaling and potentially modifies lupus susceptibility. We found that only HIN1 of p202 binds double-stranded DNA (dsDNA), while HIN2 forms a homotetramer. Crystal structures of HIN1 revealed that dsDNA is bound on face opposite the site used in AIM2 and IFI16. The structure of HIN2 revealed a dimer of dimers, the face analogous to the HIN1 dsDNA binding site being a dimerization interface. Electron microscopy imaging showed that HIN1 is flexibly linked to HIN2 in p202, and tetramerization provided enhanced avidity for dsDNA. Surprisingly, HIN2 of p202 interacts with the AIM HIN domain. We propose that this results in a spatial separation of the AIM2 pyrin domains, and indeed p202 prevented the dsDNA-dependent clustering of apoptosis-associated speck-like protein containing caspase recruitment domain (ASC) and AIM2 inflammasome activation. We hypothesize that while p202 was evolutionarily selected to limit AIM2-mediated inflammation in some mouse strains, the same mechanism contributes to increased interferon production and lupus susceptibility.

AB A key feature in Huntington disease (HD) is the accumulation of mutant Huntingtin (HTT) protein, which may be regulated by posttranslational modifications. Here, we define the primary sites of SUMO modification in the amino-terminal domain of HTT, show modification downstream of this domain, and demonstrate that HTT is modified by the stress-inducible SUMO-2. A systematic study of E3 SUMO ligases demonstrates that PIAS1 is an E3 SUMO ligase for both HTT SUMO-1 and SUMO-2 modification and that reduction of dPIAS in a mutant HTT Drosophila model is protective. SUMO-2 modification regulates accumulation of insoluble HTT in HeLa cells in a manner that mimics proteasome inhibition and can be modulated by overexpression and acute knockdown of PIAS1. Finally, the accumulation of SUMO-2-modified proteins in the insoluble fraction of HD postmortem striata implicates SUMO-2 modification in the age-related pathogenic accumulation of mutant HTT and other cellular proteins that occurs during HD progression.

AB The dynamics of mitochondrial biogenesis and function is a complex interplay of cellular and molecular processes that ultimately shape bioenergetics capacity. Mitochondrial mass, by itself, represents the net balance between rates of biogenesis and degradation. Mitochondrial biogenesis is dependent on different signaling cascades and transcriptional complexes that promote the formation and assembly of mitochondria-a process that is heavily dependent on timely and coordinated transcriptional control of genes encoding for mitochondrial proteins. In this article, we discuss the major signals and transcriptional complexes, programming mitochondrial biogenesis, and bioenergetic activity. This regulatory network represents a new therapeutic window into the treatment of the wide spectrum of mitochondrial and neurodegenerative diseases characterized by dysregulation of mitochondrial dynamics and bioenergetic deficiencies.

AB Autoimmune skin disease occurs in pregnancy, and treatment is often required to control both maternal disease and fetal outcomes. Here we present the available safety data in pregnancy and lactation for medications used to treat autoimmune skin diseases, including cutaneous lupus erythematosus, dermatomyositis, morphea and systemic sclerosis, pemphigus vulgaris, pemphigus foliaceus, and pemphigoid gestationis. A PubMed search of the English-language literature using keywords, "pregnancy" "rheumatic disease," and "connective tissue disease" was performed. Relevant articles found in the search and references were included. Reasonable evidence supports the careful and cautious use of topical steroids, topical calcineurin inhibitors, systemic corticosteroids, hydroxychloroquine, and azathioprine in pregnancy. Case reports or clinical experience suggest intravenous immunoglobulin, dapsone, phototherapy, rituximab, and plasmapheresis may be safe. Several treatment options exist for autoimmune skin disease in pregnancy and lactation, and should be considered when treating these patients.

AB Microbial biofilms are responsible for a variety of microbial infections in different parts of the body, such as urinary tract infections, catheter infections, middle-ear infections, gingivitis, caries, periodontitis, orthopedic implants, and so on. The microbial biofilm cells have properties and gene expression patterns distinct from planktonic cells, including phenotypic variations in enzymic activity, cell wall composition and surface structure, which increase the resistance to antibiotics and other antimicrobial treatments. There is consequently an urgent need for new approaches to attack biofilm-associated microorganisms, and antimicrobial photodynamic therapy (aPDT) may be a promising candidate. aPDT involves the combination of a nontoxic dye and low-intensity visible light which, in the presence of oxygen, produces cytotoxic reactive oxygen species. It has been demonstrated that many biofilms are susceptible to aPDT, particularly in dental disease. This review will focus on aspects of aPDT that are designed to increase efficiency against biofilms modalities to enhance penetration of photosensitizer into biofilm, and a combination of aPDT with biofilm-disrupting agents.

AB BACKGROUND & AIMS: Weight regain or insufficient loss after Roux-en-Y gastric bypass (RYGB) is common. This is partially attributable to dilatation of the gastrojejunostomy (GJ), which diminishes the restrictive capacity of RYGB. Endoluminal interventions for GJ reduction are being explored as alternatives to revision surgery. We performed a randomized, blinded, sham-controlled trial to evaluate weight loss after sutured transoral outlet reduction (TORe). METHODS: Patients with weight regain or inadequate loss after RYGB and GJ diameter greater than 2 cm were assigned randomly to groups that underwent TORe (n = 50) or a sham procedure (controls, n = 27). Intraoperative performance, safety, weight loss, and clinical outcomes were assessed. RESULTS: Subjects who received TORe had a significantly greater mean percentage weight loss from baseline (3.5%; 95% confidence interval, 1.8%-5.3%) than controls (0.4%; 95% confidence interval, 2.3% weight gain to 3.0% weight loss) (P = .021), using a last observation carried forward intent-to-treat analysis. As-treated analysis also showed greater mean percentage weight loss in the TORe group than controls (3.9% and 0.2%, respectively; P = .014). Weight loss or stabilization was achieved in 96% subjects receiving TORe and 78% of controls (P = .019). The TORe group had reduced systolic and diastolic blood pressure (P < .001) and a trend toward improved metabolic indices. In addition, 85% of the TORe group reported compliance with the healthy lifestyle eating program, compared with 53.8% of controls; 83% of TORe subjects said they would undergo the procedure again, and 78% said they would recommend the procedure to a friend. The groups had similar frequencies of adverse events. CONCLUSIONS: A multicenter randomized trial provides Level I evidence that TORe reduces weight regain after RYGB. These results were achieved using a superficial suction-based device; greater levels of weight loss could be achieved with newer, full-thickness suturing devices. TORe is one approach to avoid weight regain; a longitudinal multidisciplinary approach with dietary counseling and behavioral changes are required for long-term results.

AB BACKGROUND & AIMS: Proprotein convertase 1/3 (PC1/3) deficiency, an autosomal-recessive disorder caused by rare mutations in the proprotein convertase subtilisin/kexin type 1 (PCSK1) gene, has been associated with obesity, severe malabsorptive diarrhea, and certain endocrine abnormalities. Common variants in PCSK1 also have been associated with obesity in heterozygotes in several population-based studies. PC1/3 is an endoprotease that processes many prohormones expressed in endocrine and neuronal cells. We investigated clinical and molecular features of PC1/3 deficiency. METHODS: We studied the clinical features of 13 children with PC1/3 deficiency and performed sequence analysis of PCSK1. We measured enzymatic activity of recombinant PC1/3 proteins. RESULTS: We identified a pattern of endocrinopathies that develop in an age-dependent manner. Eight of the mutations had severe biochemical consequences in vitro. Neonates had severe malabsorptive diarrhea and failure to thrive, required prolonged parenteral nutrition support, and had high mortality. Additional endocrine abnormalities developed as the disease progressed, including diabetes insipidus, growth hormone deficiency, primary hypogonadism, adrenal insufficiency, and hypothyroidism. We identified growth hormone deficiency, central diabetes insipidus, and male hypogonadism as new features of PCSK1 insufficiency. Interestingly, despite early growth abnormalities, moderate obesity, associated with severe polyphagia, generally appears. CONCLUSIONS: In a study of 13 children with PC1/3 deficiency caused by disruption of PCSK1, failure of enteroendocrine cells to produce functional hormones resulted in generalized malabsorption. These findings indicate that PC1/3 is involved in the processing of one or more enteric hormones that are required for nutrient absorption.

AB In the last decade, Collaborative Problem Solving (CPS) has become a popular approach to managing the challenging behaviors of children and adolescents, and has established a growing evidence base for reducing oppositional behavior and related outcomes. In contrast with standard behavioral methods that provide incentives for meeting adult expectations, CPS focuses on identifying and treating lagging cognitive skills that interfere with children's ability to meet these expectations. Since the majority of CPS outcomes have been evaluated in clinical and educational settings as part of internal quality-improvement efforts, only a small proportion of these findings has been published in peer-reviewed academic journals. Here, we describe the CPS approach and provide a summary of all known published and unpublished findings related to its implementation in outpatient, inpatient, residential, juvenile justice, and educational settings. Finally, we provide specific recommendations for future research on the model.

AB While color video endoscopy has enabled wide-field examination of the gastrointestinal tract, it often misses or incorrectly classifies lesions. Many of these missed lesions exhibit characteristic three-dimensional surface topographies. An endoscopic system that adds topographical measurements to conventional color imagery could therefore increase lesion detection and improve classification accuracy. We introduce photometric stereo endoscopy (PSE), a technique which allows high spatial frequency components of surface topography to be acquired simultaneously with conventional two-dimensional color imagery. We implement this technique in an endoscopic form factor and demonstrate that it can acquire the topography of small features with complex geometries and heterogeneous optical properties. PSE imaging of ex vivo human gastrointestinal tissue shows that surface topography measurements enable differentiation of abnormal shapes from surrounding normal tissue. Together, these results confirm that the topographical measurements can be obtained with relatively simple hardware in an endoscopic form factor, and suggest the potential of PSE to improve lesion detection and classification in gastrointestinal imaging.

Recently, we developed a new method termed "diffuse fluorescence flow cytometry" (DFFC) that uses diffuse photons to increase the blood sampling volume and sensitivity versus existing in vivo flow cytometry methods. In this work, we describe a new DFFC prototype with approximately an order-of-magnitude improvement in sensitivity compared to our previous work. This sensitivity improvement is enabled by a number of technical innovations, which include a method for the removal of motion artifacts (allowing interrogation of mouse hindlegs that was less optically attenuating versus the tail) and improved collection optics and signal pre-amplification. We validated our system first in limb mimicking optical flow phantoms with fluorescent microspheres and then in nude mice with fluorescently labeled mesenchymal stem cells at injected concentrations of 5 x 10(3) cells/mL. In combination, these improvements resulted in an overall cell counting sensitivity of about 1 cell/mL or better in vivo. (C) The Authors.

AB High-resolution angiography and total average blood flow measurements in the rat retina using optical coherence tomography (OCT) are presented. Recently, an en face integration method, which does not require explicit calculation of vessel angles, was introduced to calculate blood flow using Doppler OCT. Using this method, rapid two-dimensional scanning has been shown to quantify pulsatile flow. However, high scanning speeds sacrifice transverse sampling density and may lead to biased velocity estimates. Alternatively, we show here that by using a volumetric scanning protocol that asynchronously samples a single vessel with respect to the heartbeat, it is possible to obtain accurate time-averaged flow measurements, even without explicit information about the pulsatile waveform. Total average retinal blood flows calculated using either arteries or veins are comparable, supporting the accuracy of this method. (C) 2013 Society of Photo-Optical Instrumentation Engineers (SPIE)

AB Purpose: To examine the current radiographic follow-up recommendations of thoracic radiologists after detection of a new opacity, suspected to be pneumonia, on chest radiography.Materials and Methods: An anonymized, Institutional Review Board-approved, Internet-based survey was sent to the 735 members of the Society of Thoracic Radiology by e-mail. Questions focused on individual practices and institutional policies after radiographic detection of suspected pneumonia. Univariate and multivariable logistic regression analyses were used to evaluate for possible associations between recommendation practices and demographic variables, various clinical situations, and radiographic features.Results: Of the 209 radiologists who responded, 42% always recommended follow-up radiographs for new opacities detected on chest radiographs, 55% sometimes recommended follow-up, and 2% never recommended follow-up. Univariate logistic regression analysis revealed that years in practice (P=0.0043) and number of outpatient posterior-anterior and lateral chest radiographs interpreted per week (P=0.027) were significant predictors of the recommendation practices. In addition, the multivariable logistic regression analysis pointed to the type of practice (academic vs. private) as an additional independent predictor of the recommendation practices (P=0.0294). The recommendations of those radiologists recommending follow-up sometimes were most often influenced by the radiographic appearance of the opacity and patient age. Only 4% reported an institutional policy.Conclusions: The majority of responding radiologists recommended follow-up on a case-by-case basis, influenced by multiple factors. Only a small minority reported a standardized practice at their institution. This lack of consistency demonstrates the need for a uniform, evidence-based approach.

AB OBJECTIVE: The objective of the study was to determine whether vascular and other complications are more common in pregnant women with neurofibromatosis type 1 (NF1).
STUDY DESIGN: We performed a population-based retrospective cohort study using the US Nationwide Inpatient Sample, 1988-2009, defining a cohort of pregnancy-related hospitalizations with an associated diagnosis of NF1 and comparing it with the control group not associated with NF1. Multivariable logistic regression was used to adjust for suspected confounders.
RESULTS: Among 19 million pregnancy-related admissions between 1988 and 2009, we identified 1553 associated with NF1 (prevalence 0.008%). A diagnosis of NF1 in delivering mothers was associated with gestational hypertension (adjusted odds ratio [AOR], 1.6, 95% confidence interval [CI], 1.2-2.0), preeclampsia (AOR, 2.8, 95% CI, 2.3-3.4), intrauterine growth restriction (AOR, 4.6, 95% CI, 3.7-5.6), cerebrovascular disease (OR, 8.1, 95% CI, 2.6-25.4), preterm labor (AOR, 1.6, 95% CI, 1.4-1.9), and cesarean delivery (AOR, 2.0, 95% CI, 1.8-2.3). Women with NF1 were not significantly more likely to have deep venous thrombosis/pulmonary embolism, acute cardiac events, or stillbirth or to die during their hospitalizations compared with the general obstetric population.
CONCLUSION: NF1 was associated with increased maternal morbidity in pregnancy (including hypertensive and cerebrovascular complications) but not increased maternal mortality. Obstetricians should be aware of the potential for increased antenatal and peripartum complications among women with NF1.

AB Experimental hydronephrosis induced by partial ureteral obstruction at 3 wk of age causes hypertension and renal impairment in adult rats and mice. Signaling by Ephrin receptors (Eph) and their ligands (ephrins) importantly regulates embryonic development. Genetically modified mice, where the cytoplasmic domain of the EphA4 receptor has been substituted by enhanced green fluorescent protein (EphA4(gf/gf)), develop spontaneous hydronephrosis and provide a model for further studies of the disorder. The present study aimed to determine if animals with congenital hydronephrosis develop hypertension and renal injuries, similar to that of experimental hydronephrosis. Ultrasound and Doppler techniques were used to visualize renal impairment in the adult mice. Telemetric blood pressure measurements were performed in EphA4(gf/gf) mice and littermate controls (EphA4(+/+)) during normal (0.7% NaCl)- and high (4% NaCl)-sodium conditions. Renal excretion, renal plasma flow, and glomerular filtration were studied, and histology and morphology of the kidneys and ureters were performed. EphA4(gf/gf) mice developed variable degrees of hydronephrosis that correlated with their blood pressure level. In contrast to EphA4(+/+), the EphA4(gf/gf) mice displayed salt-sensitive hypertension, reduced urine concentrating ability, reduced renal plasma flow, and lower glomerular filtration rate. Kidneys from EphA4(gf/gf) mice showed increased renal injuries, as evidenced by fibrosis, inflammation, and glomerular and tubular changes. In conclusion, congenital hydronephrosis causes hypertension and renal damage, similar to that observed in experimentally induced hydronephrosis. This study further reinforces the supposed causal link between hydronephrosis and later development of hypertension in humans.

TI The emerging role of the bitter taste receptor T2R38 in upper
respiratory infection and chronic rhinosinusitis

SYSTEMS; POLYPS
AB Background: Maintaining a clean upper respiratory tract requires efficient detection of pathogenic bacteria so that the airway mucosa can mount proper defenses to neutralize and clear the offending microbes. Bitter taste receptors (T2Rs) may play a critical role in this process. T2Rs were originally identified in taste cells of the tongue, where they protect against the ingestion of toxic plant and/or bacterial products. However, T2Rs are also expressed in extragustatory tissue including the airways. One specific T2R isoform, T2R38, was recently shown to be expressed in cilia of sinonasal epithelial cells, suggesting that respiratory cilia may function as a chemosensory organelle, possibly to detect bacterial presence in the airway. T2R38 is encoded by the TAS2R38 gene, which has several common genetic polymorphisms that result in altered receptor functionality. Genetic variation in T2R38 may thus contribute to individual differences in susceptibility to upper airway infection. This study provides an overview of our current knowledge of T2R38 function in sinonasal defense and the implications for patients with chronic rhinosinusitis (CRS).
Methods: A literature review was performed of the current knowledge of the bitter taste receptor T2R38 in sinonasal physiology and CRS patient outcomes.
Results: Basic science research has indicated that the T2R38 receptor is activated by acyl-homoserine lactone (AHL) molecules secreted by gram-negative bacteria, including Pseudomonas aeruginosa. In sinonasal epithelial cells T2R38 stimulates an increase in nitric oxide production that increases mucociliary clearance and directly kills bacteria. Recent clinical studies have also found clinical correlations of TAS2R38 genotype with susceptibility to gram-negative upper respiratory infection as well as necessity for surgical intervention in CRS management.
Conclusion: T2R38 appears to be an important mediator of sinonasal epithelial defense, but further study is needed to more clearly determine how TAS2R38 genotype affects patient outcomes in CRS and other upper airway diseases.

AB The incidence of melanoma is rapidly increasing worldwide and the prognosis of patients with metastatic disease is still poor, with a median survival of 8-9 months and a 3-year overall survival (OS) rate less than 15% [1,2].
A complete surgical excision is the main treatment for primary cutaneous melanoma [3], but controversies about the extension of excision margins still remain [4].
Sentinel lymph node biopsy (SLNB) provides important prognostic and staging data by the identification of regional node-negative patients who would not benefit from a complete nodal dissection. However, there is no consensus in the definition of melanoma thickness to enforce the execution of the SLNB [5].
To date, Interferon-alpha (IFN-alpha) is the only approved adjuvant treatment after surgical excision of high-risk melanoma, but its indication remains still controversial [2,6].

AB While access to and control over assets can minimize women's HIV risk, little is known about the processes through which property rights violations increase the sexual transmission of HIV. The current study focused on two rural areas in Nyanza and Western Province, Kenya where HIV prevalence was high (23.8-33 %) and property rights violations were common. The current work drew on in-depth interview data collected from 50 individuals involved in the development and implementation of a community-led land and property rights program. The program was designed to respond to property rights violations, prevent disinheritance and asset stripping, and reduce HIV risk among women. In our findings, we detailed the social and economic mechanisms through which a loss of property rights was perceived to influence primary and secondary prevention of HIV. These included: loss of income, loss of livelihood and shelter, and migration to slums, markets, or beaches where the exchange of sex for food, money, shelter, clothing, or other goods was common. We also examined the perceived influence of cultural practices, such as wife inheritance, on HIV risk. In the conclusions, we made recommendations for future research in the science-base focused on the development of property ownership as a structural HIV prevention and treatment intervention.

AB In utero exposure of the embryo and fetus to radiation has been implicated in malformations or fetal death, and often produces lifelong health consequences such as cancers and mental retardation. Here we demonstrate that deletion of a G-protein-coupled purinergic receptor, P2Y(14), confers potent resistance to in utero radiation. Intriguingly, a putative P2Y(14) receptor ligand, UDP-glucose, phenocopies the effect of P2Y(14) deficiency. These data indicate that P2Y(14) is a receptor governing in utero tolerance to genotoxic stress that may be pharmacologically targeted to mitigate radiation toxicity in pregnancy.

AB Background: Physical activity (PA) has been found to be an excellent predictor of mortality beyond traditional measures in COPD. We aimed to determine the association between depression and anxiety with accelerometry-based PA in patients with COPD.
Methods: We performed a cross-sectional analysis of baseline data from 148 stable patients with COPD enrolled in an ongoing, longitudinal, observational study. We measured PA (total daily step count) with a Stepwatch Activity Monitor over 7 days, depression and anxiety with the Hospital Anxiety and Depression Scales (HADSs), dyspnea with the Shortness of Breath Questionnaire, and functional capacity with the 6-min walk test.
Results: Increased anxiety was associated with higher levels of PA such that for every one-point increase in the HADS-Anxiety score there was a corresponding increase of 288 step counts per day (beta = 288 steps, P < .001), after adjusting for all other variables. Higher levels of depressive symptoms were associated with lower PA (beta = -176 steps, P = .02) only when anxiety was in the model. The interaction term for anxiety and depression approached significance (beta = 26, P = .10), suggesting that higher levels of anxiety mitigate the negative effects of depression on PA.
Conclusions: The increased PA associated with anxiety in COPD is, to our knowledge, a novel finding. However, it is unclear whether anxious patients with COPD are more restless, and use increased psychomotor activity as a coping mechanism, or whether those with COPD who push themselves to be more physically active experience more anxiety symptoms. Future studies should evaluate for anxiety and PA to better inform how to improve clinical outcomes.

AB Complementary and integrative strategies are widely used by families with children who have mental health diagnoses. The therapies used by these children include herbs, dietary supplements, massage, acupuncture, meditation, and naturopathy. The literature on efficacy of complementary and alternative approaches is of limited value, and studies are needed to test efficacy and safety. Interpretation of complementary and integrative health care studies for symptomatic management of mental health conditions is hampered by study design and methodological limitations. Well-designed, adequately powered, and suitably controlled clinical trials on promising complementary and integrative modalities are needed for children and adolescents with psychiatric conditions.

AB The primary aim of this randomized trial is to evaluate whether a standardized uterosacral ligament suspension colpopexy (USLSC), added to a planned hysterectomy for an indication other than pelvic organ prolapse (POP), decreases the rate of subsequent vaginal vault prolapse in women without preoperative symptomatic POP. Secondary aims include comparison of perioperative complications, urinary, bowel and sexual functions between subjects with and without concomitant USLSC. If shown to be beneficial, the cost-effectiveness of prophylactic USLSC at the time of hysterectomy will be evaluated. This trial will be performed at 4 centers across the United States. The data will be analyzed by the data-coordinating center of the Southern California Kaiser Permanente. Standardized questionnaires and objective measurements will be obtained. The patients and providers performing assessments are masked to treatment assignment The primary outcome, defined as absence of POP at/distal to the hymen on Pelvic Organ Prolapse Quantitative examination, will be determined 12 months post-operatively. Secondary outcomes include: no prolapse symptoms by questionnaires, and no treatment for POP besides the prophylactic study intervention. Additional follow-up occurs annually for a total of 5 years. Accrual is projected to take 3 years. Given cost and morbidity of surgical repair of post-hysterectomy prolapse, preventive strategies are of outmost importance. The risks and benefits of prophylactic USLSC have never been studied prospectively. This trial is designed to determine if USLSC is an appropriate clinical adjunct at the time of hysterectomy, with subsequent reduction of symptomatic POP. (C) 2013 Elsevier Inc. All rights reserved.

AB This pilot study aims to provide effect size confidence intervals, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy of Dietary Approaches to Stop Hypertension (DASH) as adjunct therapy to standard care for adults with uncontrolled asthma. The DASH diet encompasses foods (e.g., fresh fruit, vegetables, and nuts) and antioxidant nutrients (e.g., vitamins A, C, E, and zinc) with potential benefits for persons with asthma, but it is unknown whether the whole diet is beneficial. Participants (n = 90) will be randomized to receive usual care alone or combined with a DASH intervention consisting of 8 group and 3 individual sessions during the first 3 months, followed by at least monthly phone consultations for another 3 months. Follow-up assessments will occur at 3 and 6 months. The primary outcome measure is the 7-item juniper Asthma Control Questionnaire, a validated composite measure of daytime and nocturnal symptoms, activity limitations, rescue medication use, and percentage predicted forced expiratory volume in 1 second. We will explore changes in inflammatory markers important to asthma pathophysiology (e.g., fractional exhaled nitric oxide) and their potential to mediate the intervention effect on disease control. We will also conduct pre-specified subgroup analyses by genotype (e.g., polymorphisms on the glutathione S transferase gene) and phenotype (e.g., atopy, obesity). By evaluating a dietary pattern approach to improving asthma control, this study could advance the evidence base for refining clinical guidelines and public health recommendations regarding the role of dietary modifications in asthma management.

AB Patients with low socioeconomic status (SES) use more acute hospital care and less primary care than patients with high socioeconomic status. This low-value pattern of care use is harmful to these patients' health and costly to the health care system. Many current policy initiatives, such as the creation of accountable care organizations, aim to improve both health outcomes and the cost-effectiveness of health services. Achieving those goals requires understanding what drives low-value health care use. We conducted qualitative interviews with forty urban low-SES patients to explore why they prefer to use hospital care. They perceive it as less expensive, more accessible, and of higher quality than ambulatory care. Efforts that focus solely on improving the quality of hospital care to reduce readmissions could, paradoxically, increase hospital use. Two different profile types emerged from our research. Patients in Profile A (five or more acute care episodes in six months) reported social dysfunction and disability. Those in Profile B (fewer than five acute care episodes in six months) reported social stability but found accessing ambulatory care to be difficult. Interventions to improve outcomes and values need to take these differences into account.

DT Article
ID UNITED-STATES; ELDERLY-PATIENTS; TRENDS; ADMISSIONS
AB With US emergency care characterized as "at the breaking point," we studied how the aging of the US population would affect demand for emergency department (ED) services and hospitalizations in the coming decades. We applied current age-specific ED visit rates to the population structure anticipated by the Census Bureau to exist through 2050. Our results indicate that the aging of the population will not cause the number of ED visits to increase any more than would be expected from population growth. However, the data do predict increases in visit lengths and the likelihood of hospitalization. As a result, the aggregate amount of time patients spend in EDs nationwide will increase 10 percent faster than population growth. This means that ED capacity will have to increase by 10 percent, even without an increase in the number of visits. Hospital admissions from the ED will increase 23 percent faster than population growth, which will require hospitals to expand capacity faster than required by raw population growth alone.

AB Annually, more than 1 million patients are hospitalized for heart failure (HF), translating to high healthcare utilization and cost burden. Among patients with hospitalized HF (HHF), approximately 50% have HF with preserved ejection fraction (HFpEF) and 50% have HF with reduced ejection fraction (HFrEF), with the proportion of patients with HFpEF increasing with time. This article defines the epidemiologic landscape of patients with HHF, comparing and contrasting those with HFpEF and HFrEF, and identifies key areas that require further investigation. More complete characterization of these populations may be the first step to developing effective therapies.

AB Despite low inpatient mortality and effective symptomatic management, patients hospitalized for heart failure (HHF) experience high postdischarge mortality and rehospitalization rates. HHF represents a widely heterogeneous population with distinct clinical subsets that may require tailored management approaches. Despite this, however, HHF patients are almost uniformly managed with intravenous diuretics, with low uptake of new therapies during hospitalization. This article proposes a practical approach to classifying HHF patients that is focused on guiding individualized inpatient and postdischarge management. HHF is not a single disease but a manifestation of several cardiac and noncardiac processes and thus should be approached as such.

AB Hospitalized heart failure (HHF) is associated with unacceptably high postdischarge mortality and rehospitalization rates. This heterogeneous group of patients, however, is still treated with standard, homogenous therapies that are not preventing their rapid deterioration. The costs associated with HHF have added demands from society, government, and payers to improve outcomes. With coordinated and committed efforts in the development of new therapies, improvements may be seen in outcomes for patients with HHF. This article summarizes concepts in developing therapies for HHF discussed during a multidisciplinary panel at the Heart Failure Society of America's Annual Scientific Meeting, September 2012.

AB Hospitalizations for heart failure (HF) are increasing, and HF is the primary cause of readmission for all Medicare patients. Inpatient HF mortality is poor, but most morbidity and mortality occurs after hospital discharge. Readmissions attributable to HF persist or increase over time after discharge, and past HF admissions predict both readmission and mortality. The heightened risk of readmission dissipates slowly after discharge, suggesting that any intervention should be part of a lasting care package in the outpatient setting. Interventions that apply to multiple common medical comorbidities may be more likely to reduce overall adverse events.

AB Hospitalization for heart failure (HHF) is commonly associated with symptomatic improvement in response to standard medical therapy, yet there remains a substantial risk of rehospitalization and death. Clinically stable outpatients and decompensated inpatients represent two types of patients with chronic heart failure. In the former, treatment of common heart rhythm disorders with nonpharmacologic electrophysiology-based interventions is of substantial benefit in select patients. The potential benefits of these interventions in the hospitalized setting are not well studied. In this review, current knowledge is discussed and future research directions are suggested with nonpharmacologic electrophysiology-based interventions to reduce the morbidity and mortality associated with patients with HHF.

AB Thrombopoietin (TPO) is the major physiological regulator of platelet production. TPO binds the TPO receptor, activates JAK and STAT pathways, thus stimulating megakaryocyte growth and platelet production. There is no "sensor" of the platelet count; rather TPO is produced in the liver at a constant rate and cleared by TPO receptors on platelets. TPO levels are inversely proportional to the rate of platelet production. Early recombinant TPO molecules were potent stimulators of platelet production and increased platelets in patients with immune thrombocytopenia, chemotherapy-induced thrombocytopenia, myelodysplastic syndromes and platelet apheresis donors. Neutralizing antibodies formed against one recombinant protein and ended their development. A second generation of TPO receptor agonists, romiplostim and eltrombopag, has been developed. Romiplostim is an IgG heavy chain into which four TPO agonist peptides have been inserted. Eltrombopag is an oral small molecule. These activate the TPO receptor by different mechanisms to increase megakaryocyte growth and platelet production. After administration of either to healthy volunteers, there is a delay of 5 days before the platelet count rises and subsequently reaches a peak after 12-14 days. Both have been highly effective in treating ITP and hepatitis C thrombocytopenia. Studies in a wide variety of other thrombocytopenic conditions are underway.

AB PURPOSE. To develop and validate a novel automated system to assess ocular redness (OR) in clinical images.
METHODS. We developed a novel software that quantifies OR in digital images based on a mathematic algorithm using a centesimal continuous scoring scale. Subsequently, we conducted a study to validate the scores obtained with this system by correlating them with those obtained by two physicians using two image-based comparative subjective scales, the Efron and the Validated Bulbar Redness (VBR) grading scales. Additionally, we evaluated the level of clinical agreement between the Ocular Redness Index (ORI) score and the two image-based methods by means of the Bland-Altman analysis. Main outcome measures included correlation and level of agreement between the ORI score, Efron score, and the VBR score.
RESULTS. One hundred and two clinical photographs of eyes with OR were evaluated. The ORI scores significantly correlated with the scores obtained by the two clinicians using the Efron (Observer 1, R = 0.925, P < 0.001; Observer 2, R = 0.857, P < 0.001), and VBR (Observer 1, R = 0.830, P < 0.001; Observer 2, R = 0.821, P < 0.001) scales. The Bland-Altman analysis revealed levels of disagreement of up to 30 and 27 units for the ORI-Efron and ORI-VBR score comparisons, respectively.
CONCLUSIONS. The ORI provides an objective and continuous scale for evaluating ocular injection in an automated manner, and without need for a trained physician for scoring. The ORI may be used as a new alternative for objective OR evaluation in clinics and in clinical trials.

AB PURPOSE. We tested the hypothesis that retinal blood flow has a postocclusive reactive hyperemia response modulated by occlusion duration and metabolic activity, and that choroidal blood flow does not.
METHODS. Anesthetized and paralyzed rats (n = 34) were studied. Retinal and choroidal blood flow was measured by laser speckle imaging and laser Doppler flowmetry, respectively. Blood oxygenation level-dependent functional magnetic resonance imaging (BOLD fMRI) was used to measure changes in relative blood oxygenation of the retinal and choroidal circulations. Transient carotid occlusion was elicited with a hydraulic occluder on the common carotid artery. Several occlusion durations were tested during dark, constant light, and flicker light conditions to modulate metabolic demand. The hyperemia response magnitude was quantified by integrating the area above the blood flow baseline for the 3 minutes after release of the occlusion.
RESULTS. Systemic arterial pressure (108.2 +/- 1.4 mm Hg) was unaffected by the carotid occlusions, and was similar among animals and conditions. Retinal blood flow had a reactive hyperemia, but choroidal blood flow did not (e.g., 14 +/- 2%.sec versus 0.5 +/- 4%.sec after 60-second occlusion). The hyperemia magnitude increased as a nonlinear function of occlusion duration and reached a plateau at occlusion durations <60 second. The hyperemia magnitude was not altered by different lighting conditions at occlusion durations of 15 and 60 seconds. BOLD fMRI results were similar to the laser-based blood flow measurements.
CONCLUSIONS. The results indicate that metabolic local control has a negligible role in choroidal blood flow regulation and only partially accounts for the blood flow behavior in the retinal circulation.

AB Obesity and diabetes mellitus are associated with an increased risk of pancreatic cancer. These associations may be secondary to consequences of peripheral insulin resistance, pancreatic -cell dysfunction, or hyperglycemia itself. Hemoglobin A1c (HbA1c) is a measure of hyperglycemia, whereas plasma insulin and proinsulin are markers of peripheral insulin resistance, and the proinsulin to insulin ratio marks pancreatic -cell dysfunction.
This was a prospective, nested case-control study of 449 case patients and 982 control subjects with prediagnostic blood samples and no diabetes history from five prospective US cohorts followed through 2008. Two or three control subjects were matched to each case patient by year of birth, cohort, smoking, and fasting status. Pancreatic cancer risk was assessed by prediagnostic HbA1c, insulin, proinsulin, and proinsulin to insulin ratio with multivariable-adjusted logistic regression. All P values were two-sided.
The highest vs lowest quintiles of HbA1c, insulin, and proinsulin were associated with with an increased risk for pancreatic cancer (odds ratio [OR] 1.79; 95% confidence interval [CI] 1.17 to 2.72, P-trend .04 for HbA1c; OR 1.57; 95% CI 1.08 to 2.30; Ptrend .002 for insulin; and OR 2.22; 95% CI 1.50 to 3.29; P-trend < .001 for proinsulin). Proinsulin to insulin ratio was not associated with pancreatic cancer risk. Results were similar across studies (all P-heterogeneity > .29). In cancers developing 10 or more years after blood collection, the associations with insulin and proinsulin became stronger (highest vs lowest quintile, OR 2.77; 95% CI 1.28 to 5.99 for insulin and OR 3.60; 95% CI 1.68 to 7.72 for proinsulin). In mutually adjusted models including HbA1c, insulin, and proinsulin, only proinsulin remained statistically significant ( highest vs lowest quintile, OR 2.55; 95% CI 1.54 to 4.21; Ptrend < .001).
Among participants from five large prospective cohorts, circulating markers of peripheral insulin resistance, rather than hyperglycemia or pancreatic -cell dysfunction, were independently associated with pancreatic cancer risk.

TI Prediction of Late Disease Recurrence and Extended Adjuvant Letrozole

AB Biomarkers to optimize extended adjuvant endocrine therapy for women with estrogen receptor (ER)positive breast cancer are limited. The HOXB13/IL17BR (H/I) biomarker predicts recurrence risk in ER-positive, lymph nodenegative breast cancer patients. H/I was evaluated in MA.17 trial for prognostic performance for late recurrence and treatment benefit from extended adjuvant letrozole.
A prospectiveretrospective, nested case-control design of 83 recurrences matched to 166 nonrecurrences from letrozole- and placebo-treated patients within MA.17 was conducted. Expression of H/I within primary tumors was determined by reverse-transcription polymerase chain reaction with a prespecified cutpoint. The predictive ability of H/I for ascertaining benefit from letrozole was determined using multivariable conditional logistic regression including standard clinicopathological factors as covariates. All statistical tests were two-sided.
High H/I was statistically significantly associated with a decrease in late recurrence in patients receiving extended letrozole therapy (odds ratio [OR] 0.35; 95% confidence interval [CI] 0.16 to 0.75; P .007). In an adjusted model with standard clinicopathological factors, high H/I remained statistically significantly associated with patient benefit from letrozole (OR 0.33; 95% CI 0.15 to 0.73; P .006). Reduction in the absolute risk of recurrence at 5 years was 16.5% for patients with high H/I (P .007). The interaction between H/I and letrozole treatment was statistically significant (P .03).
In the absence of extended letrozole therapy, high H/I identifies a subgroup of ER-positive patients disease-free after 5 years of tamoxifen who are at risk for late recurrence. When extended endocrine therapy with letrozole is prescribed, high H/I predicts benefit from therapy and a decreased probability of late disease recurrence.

CONTROLLED 18-MONTH TRIAL; ADD-ON TREATMENT; DOUBLE-BLIND
AB Objective: Owing to the prevalence of medication side effects and treatment resistance, prescribers often consider off-label uses of US Food and Drug Administration (FDA)-approved agents for the treatment of persistent symptoms. The authors review the available literature on the FDA-approved and non-FDA-approved uses of lamotrigine in adults with psychiatric disorders.
Data Sources: We used PubMed, MEDLINE, and a hand search of relevant literature to find studies published between 1990 and 2012 and available in English language. The following keywords were searched: lamotrigine, psychiatric, mood disorders, depression, personality disorders, anxiety, schizophrenia, side effects, and rash.
Study Selection: Data were selected from 29 randomized controlled trials (RCTs). When RCTs were not available, open-label trials (6), retrospective case reviews (10), and case series (4) were summarized.
Data Extraction: We extracted results of monotherapy and augmentation trials of lamotrigine on primary and secondary outcome measures.
Results: Lamotrigine is generally well tolerated, with the best evidence for the maintenance treatment of bipolar disorder, particularly in prevention of depressive episodes. In acute bipolar depression, meta-analyses suggested a modest benefit, especially for more severely depressed subjects, with switch rates similar to placebo. In unipolar depression, double-blind RCTs noted benefit on subsets of symptoms and improved response in more severely depressed subjects. Data are limited but promising in borderline personality disorder. Use of lamotrigine in schizophrenia and anxiety disorders has little supportive evidence.
Conclusions: Lamotrigine is recommended in bipolar maintenance when depression is prominent. It also has a role in treating acute bipolar depression and unipolar depression, though the latter warrants more research. Data are too limited in other psychiatric disorders to recommend its use at this time. (C) Copyright 2013 Physicians Postgraduate Press, Inc.

AB We describe a hand therapy protocol aimed at unloading the wrist and increasing blood supply to the wrist, specifically to the lunate. The protocol was used in a series of patients with clinical radial wrist pain, dysfunction and changes on wrist imaging studies. The patients were not candidates for surgical treatment. Application of the therapy protocol improved objective and subjective parameters such as pain and motion, and may provide a viable treatment option for patients with lunate overload or early Kienbock's disease that are not candidates for surgery.

AB The discovery of chromosomal rearrangements involving the anaplastic lymphoma kinase (ALK) gene in non-small cell lung cancer (NSCLC) has stimulated renewed interest in oncogenic fusions as potential therapeutic targets. Recently, genetic alterations in ROS1 and RET were identified in patients with NSCLC. Like ALK, genetic alterations in ROS1 and RET involve chromosomal rearrangements that result in the formation of chimeric fusion kinases capable of oncogenic transformation. Notably, ROS1 and RET rearrangements are rarely found with other genetic alterations, such as EGFR, KRAS, or ALK. This finding suggests that both ROS1 and RET are independent oncogenic drivers that may be viable therapeutic targets. In initial screening studies, ROS1 and RET rearrangements were identified at similar frequencies (approximately 1%-2%), using a variety of genotyping techniques. Importantly, patients with either ROS1 or RET rearrangements appear to have unique clinical and pathologic features that may facilitate identification and enrichment strategies. These features may in turn expedite enrollment in clinical trials evaluating genotype-directed therapies in these rare patient populations. In this review, we summarize the molecular biology, clinical features, detection, and targeting of ROS1 and RET rearrangements in NSCLC.

AB Numerous obesity loci have been identified using genome-wide association studies. A UK study indicated that physical activity may attenuate the cumulative effect of 12 of these loci, but replication studies are lacking. Therefore, we tested whether the aggregate effect of these loci is diminished in adults of European ancestry reporting high levels of physical activity. Twelve obesity-susceptibility loci were genotyped or imputed in 111,421 participants. A genetic risk score (GRS) was calculated by summing the BMI-associated alleles of each genetic variant. Physical activity was assessed using self-administered questionnaires. Multiplicative interactions between the GRS and physical activity on BMI were tested in linear and logistic regression models in each cohort, with adjustment for age, age(2), sex, study center (for multicenter studies), and the marginal terms for physical activity and the GRS. These results were combined using meta-analysis weighted by cohort sample size. The meta-analysis yielded a statistically significant GRS x physical activity interaction effect estimate (P-interaction = 0.015). However, a statistically significant interaction effect was only apparent in North American cohorts (n = 39,810, P-interaction = 0.014 vs. n = 71,611, P-interaction = 0.275 for Europeans). In secondary analyses, both the FTO rs1121980 (P-interaction = 0.003) and the SEC16B rs10913469 (P-interaction = 0.025) variants showed evidence of SNP x physical activity interactions. This meta-analysis of 111,421 individuals provides further support for an interaction between physical activity and a GRS in obesity disposition, although these findings hinge on the inclusion of cohorts from North America, indicating that these results are either population-specific or non-causal.

AB NTRK3 is a member of the neurotrophin receptor family and regulates cell survival. It appears to be a dependence receptor, and thus has the potential to act as an oncogene or as a tumor suppressor gene. NTRK3 is a receptor for NT-3 and when bound to NT-3 it induces cell survival, but when NT-3 free, it induces apoptosis. We identified aberrantly methylated NTRK3 in colorectal cancers through a genome-wide screen for hypermethylated genes. This discovery led us to assess whether NTRK3 could be a tumor suppressor gene in the colon. NTRK3 is methylated in 60% of colon adenomas and 67% of colon adenocarcinomas. NTRK3 methylation suppresses NTRK3 expression. Reconstitution of NTRK3 induces apoptosis in colorectal cancers, if NT-3 is absent. Furthermore, the loss of NTRK3 expression associates with neoplastic transformation in vitro and in vivo. We also found that a naturally occurring mutant NTRK3 found in human colorectal cancer inhibits the tumor suppressor activity of NTRK3. In summary, our findings suggest NTRK3 is a conditional tumor suppressor gene that is commonly inactivated in colorectal cancer by both epigenetic and genetic mechanisms whose function in the pathogenesis of colorectal cancer depends on the expression status of its ligand, NT-3.

AB UV-induced DNA damage causes repression of RNA synthesis. Following the removal of DNA lesions, transcription recovery operates through a process that is not understood yet. Here we show that knocking-out of the histone methyltransferase DOT1L in mouse embryonic fibroblasts (MEF DOT1L) leads to a UV hypersensitivity coupled to a deficient recovery of transcription initiation after UV irradiation. However, DOT1L is not implicated in the removal of the UV-induced DNA damage by the nucleotide excision repair pathway. Using FRAP and ChIP experiments we established that DOT1L promotes the formation of the pre-initiation complex on the promoters of UV-repressed genes and the appearance of transcriptionally active chromatin marks. Treatment with Trichostatin A, relaxing chromatin, recovers both transcription initiation and UV-survival. Our data suggest that DOT1L secures an open chromatin structure in order to reactivate RNA Pol II transcription initiation after a genotoxic attack.

TI Association Study of Common Genetic Variants and HIV-1 Acquisition in

AB Multiple genome-wide association studies (GWAS) have been performed in HIV-1 infected individuals, identifying common genetic influences on viral control and disease course. Similarly, common genetic correlates of acquisition of HIV-1 after exposure have been interrogated using GWAS, although in generally small samples. Under the auspices of the International Collaboration for the Genomics of HIV, we have combined the genome-wide single nucleotide polymorphism (SNP) data collected by 25 cohorts, studies, or institutions on HIV-1 infected individuals and compared them to carefully matched population-level data sets (a list of all collaborators appears in Note S1 in Text S1). After imputation using the 1,000 Genomes Project reference panel, we tested approximately 8 million common DNA variants (SNPs and indels) for association with HIV-1 acquisition in 6,334 infected patients and 7,247 population samples of European ancestry. Initial association testing identified the SNP rs4418214, the C allele of which is known to tag the HLA-B*57:01 and B*27:05 alleles, as genome-wide significant (p=3.6x10(-11)). However, restricting analysis to individuals with a known date of seroconversion suggested that this association was due to the frailty bias in studies of lethal diseases. Further analyses including testing recessive genetic models, testing for bulk effects of non-genome-wide significant variants, stratifying by sexual or parenteral transmission risk and testing previously reported associations showed no evidence for genetic influence on HIV-1 acquisition (with the exception of CCR5 Delta 32 homozygosity). Thus, these data suggest that genetic influences on HIV acquisition are either rare or have smaller effects than can be detected by this sample size.

AB Associations between PTSD and difficulties in intimate relationships have prompted national calls for partner-involvement in treatment for PTSD. However, research is limited evaluating patient preferences for the format of these services or predictors of these preferences. Such information is vital to shaping services so they are relevant to those most interested in them and to those with greatest need. To address these gaps, we surveyed 185 coupled veterans as they presented for mental health appointments at a VA PTSD treatment clinic. We assessed broad interest in greater partner-involvement, specific interest in couple therapy, and potential predictors of these interests, including family concerns, relationship satisfaction, PTSD symptom severity, and combat era. We found unique positive associations between interest in partner-involvement and both family concerns and relationship satisfaction, suggesting those most interested in partner-involvement are likely those experiencing the greatest family concerns and the most satisfied in their intimate relationships. Associations between interest and PTSD severity were nonsignificant. Interest in couple therapy was significantly greater among returning veterans than Vietnam/Korean War Veterans. However, these two groups did not vary significantly in their interest in greater partner-involvement more broadly. Discussion of findings considers the roles of both insight into PTSD-related family problems and relationship satisfaction in motivating interest in partner-involvement in care, the potential need to address motivation for partner-involvement among veterans in distressed relationships, and the importance of alternative methods of partner-involvement to full courses of couple therapy, particularly for Vietnam/Korean War era veterans.

TI Psychosocial Changes 6 Months after Face Transplantation
SO PSYCHOSOMATICS
LA English
DT Article
ID OUTCOMES; FUTURE
AB Background: The goal of facial transplantation is to transform severely deformed features in a single, complex operation. Although nearly 20 have been completed since 2005, there is limited information about the subsequent psychosocial status of recipients. Objective: The purpose of this study is to describe such changes as captured on a variety of psychosocial measures 3 and 6 months after full facial transplantation among 3 adults who all completed a comprehensive psychiatric assessment before the procedure. Results: We hypothesized and found that participants experienced significant improvement on quality of life measures of physical and mental health based on the MOS-SF -12. While the recipients experienced a decline in their physical quality of life in the 3 months immediately after surgery, they had improvement by 6 months (p = 0.02). Overall mental health showed steady improvement from the time before surgery to 6 months later (p = 0.04). These changes, however, were not reflected in another popular measure of quality of life, the EQ-5D. There were no changes in participants ' self-esteem or dyadic function over the same period of time. Conclusion: As facial transplantation evolves from being a novel surgical procedure to an increasingly common clinical practice, future efforts to delineate the psychosocial changes experienced by recipients might include mixed methods analyses, with both qualitative and quantitative data, as well as collaborative assessment protocols shared among facial transplantation programs.

AB BACKGROUND: Ventilator-associated pneumonia (YAP) is classified as early-onset or late-onset, in part, to identify subjects at risk for infection with resistant pathogens. We assessed differences in the bacterial etiology of early-onset versus late-onset YAP. METHODS: Subjects enrolled in 2004-2006 in 2 clinical studies of doripenem versus imipenem or piperacillin/tazobactam, with a diagnosis of VAP (n = 500) were included in the analysis. Subjects were classified by ventilator status: early-onset YAP (< 5 d of ventilation) or late-onset VAP (>= 5 d of ventilation). Baseline demographics and bacterial etiology were analyzed by YAP status. RESULTS: Late-onset YAP subjects had higher Acute Physiology and Chronic Health Evaluation (APACHE II) scores (mean 16.6 versus 15.5, P = .008). There were no significant differences in Clinical Pulmonary Infection Score, sex, age, or presence of bacteremia between the groups. A total of 496 subjects had a baseline pathogen, and 50% of subjects in each group had >= 2 pathogens. With the exception of Staphylococcus aureus, which was common in early-onset YAP, the pathogens (including potentially multidrug-resistant (MDR) pathogens) isolated from early-onset versus late-onset YAP were not significantly different between groups. Acinetobacter baumannii or Pseudomonas aeruginosa with decreased susceptibility to any study drug was observed in early-onset and late-onset YAP subjects. CONCLUSIONS: There were no significant differences in the prevalence of potential MDR pathogens associated with early-onset or late-onset YAP, even in subjects with prior antibiotics. Empiric therapy for early-onset YAP should also include agents likely to be effective for potential MDR pathogens. Further prospective studies should evaluate microbiology trends in subjects with YAP.

AB In congenital mitochondrial DNA (mtDNA) disorders, a mixture of normal and mutated mtDNA (termed heteroplasmy) exists at varying levels in different tissues, which determines the severity and phenotypic expression of disease. Pearson marrow pancreas syndrome (PS) is a congenital bone marrow failure disorder caused by heteroplasmic deletions in mtDNA. The cause of the hematopoietic failure in PS is unknown, and adequate cellular and animal models are lacking. Induced pluripotent stem (iPS) cells are particularly amenable for studying mtDNA disorders, as cytoplasmic genetic material is retained during direct reprogramming. Here, we derive and characterize iPS cells from a patient with PS. Taking advantage of the tendency for heteroplasmy to change with cell passage, we isolated isogenic PS-iPS cells without detectable levels of deleted mtDNA. We found that PS-iPS cells carrying a high burden of deleted mtDNA displayed differences in growth, mitochondrial function, and hematopoietic phenotype when differentiated in vitro, compared to isogenic iPS cells without deleted mtDNA. Our results demonstrate that reprogramming somatic cells from patients with mtDNA disorders can yield pluripotent stem cells with varying burdens of heteroplasmy that might be useful in the study and treatment of mitochondrial diseases.

AB Discriminating neural abnormalities into the causes versus consequences of psychopathology would enhance the translation of neuroimaging findings into clinical practice. By regarding the traumatic encounter as a reference point for disease onset, neuroimaging studies of post-traumatic stress disorder (PTSD) can potentially allocate PTSD neural abnormalities to either predisposing (pre-exposure) or acquired (post-exposure) factors. Based on novel research strategies in PTSD neuroimaging, including genetic, environmental, twin, and prospective studies, we provide a causal model that accounts for neural abnormalities in PTSD, and outline its clinical implications. Current data suggest that abnormalities within the amygdala and dorsal anterior cingulate cortex represent predisposing risk factors for developing PTSD, whereas dysfunctional hippocampal ventromedial prefrontal cortex (vmPFC) interactions may become evident only after having developed the disorder.

AB Deregulation of microRNAs (miRNAs) can drive oncogenesis, tumor progression, and metastasis by acting cell-autonomously in cancer cells. However, solid tumors are also infiltrated by large amounts of non-neoplastic stromal cells, including macrophages, which express several active miRNAs. Tumor-associated macrophages (TAMs) enhance angiogenic, immunosuppressive, invasive, and metastatic programming of neoplastic tissue and reduce host survival. Here, we review the role of miRNAs (including miR-155, miR-146, and miR-511) in the control of macrophage production and activation, and examine whether reprogramming miRNA activity in TAMs and/or their precursors might be effective for controlling tumor progression.

AB Over a decade of research on the relationship between nurse staffing and patient outcomes has demonstrated the important role of nurses in the provision of high-quality, safe care, yet currently, no evidence-based nurse staffing guidelines exist. A systematic review of reviews was conducted to explore reasons why this is the case and recommend directions for future research to improve upon this gap. Authors of the 29 included reviews reported variability in methods and measurement approaches, lack of incorporation of nurse processes and system factors that potentially affect relationships among variables, and overall inconsistencies in results across primary studies. We propose use of an Integrated Framework for a Systems Approach to Nurse Staffing Research to inform the development of applicable conceptual models. Future studies that use a systems approach and focus on establishing causal relationships among variables will potentially strengthen the evidence and advance the science in this area.

AB ObjectiveTo quantitatively evaluate the position, size, and shape of the menisci in subjects with radiographic knee osteoarthritis (OA) compared to subjects without OA, using magnetic resonance imaging (MRI).
MethodsWe studied the right knees of 39 Osteoarthritis Initiative participants (24 women and 15 men with a mean age of 59.6 +/- 8.7 years) with medial compartment radiographic tibiofemoral OA (Kellgren/Lawrence grade of 2 or 3). Subjects were matched individually for age, sex, and height to controls without knee OA and without risk factors for knee OA. The right knees of the controls were used as references. One observer performed manual segmentation of the tibial plateau and the medial and lateral meniscus based on a coronally reconstructed double-echo steady-state sequence with water excitation, focusing on 5 central 3T MRIs.
ResultsIn OA knees, there was less meniscal coverage of the medial tibial plateau (435 mm(2) versus 515 mm(2); P = 0.0004), the medial meniscus body showed more extrusion (2.64 mm versus 0.53 mm; P < 0.0001), and the peripheral margin had a more convex shape, i.e., bulged more (mean 0.61 mm versus 0.27 mm; P < 0.0001). The thickness or volume of the medial meniscus body of OA knees did not differ substantially from reference knees. In contrast, in OA knees the lateral meniscus body had a larger volume (mean 266 mm(3) versus 224 mm(3); P = 0.0005) and extruded more (mean 1.16 mm versus -1.01 mm; P < 0.0001), and the external margin bulged more (mean 0.53 mm versus 0.35 mm; P < 0.0001), than in reference knees.
ConclusionOur findings indicate altered meniscal position and shape (i.e., more bulging) in both compartments in medial compartment knee OA. These changes may be important features of OA pathogenesis and/or disease consequences.

AB ObjectiveTo identify microRNAs (miRNAs) in human T cells that can explain known antiinflammatory properties of steroids.
MethodsActivated human CD4+ T cells from healthy donors were exposed to 1 M methylprednisolone (MP) in vitro and then subjected to miRNA and messenger RNA microarray analyses. Changes in expression profiles were recorded. Using quantitative polymerase chain reaction (qPCR), flow cytometry, and enzyme-linked immunosorbent assay (ELISA), we confirmed the suppression of predicted targets, and through miRNA transfection experiments, we could suggest mechanistic links.
ResultsWe identified numerous steroid-responsive genes and miRNAsmany known and some novelincluding multiple previously unknown proinflammatory genes suppressed by MP. Further studies using qPCR, flow cytometry, and ELISA demonstrated that methylprednisolone increased the expression of miRNA-98 (miR-98) and suppressed the levels of predicted targets, including interleukin-13 and 3 tumor necrosis factor receptors (TNFRs): Fas, FasL, and TNFR superfamily member 1B. Forced expression of miR-98 in T cells resulted in suppression of the same targets.
ConclusionThe findings of this study demonstrate a link between miR-98 expression and the effects of MP and provide evidence suggesting that MP acts through miR-98 to inhibit specific proinflammatory targets. Identification of this antiinflammatory mechanism of glucocorticoids is important, since it may pave the way toward the elusive goal of dissociating adverse effects from therapeutic effects.

AB Background and aims SAVOR-TIMI 53 was designed to study the effects of the DPP-4 inhibitor saxagliptin on cardiovascular outcomes in high risk type 2 diabetes patients with diverse levels of diabetes control and background anti-diabetic drugs. The goal of this article is to describe the baseline characteristics of this hypothesis driven study.
Materials and methods A total of 16496 diabetic patients from North America (31.9%), Western Europe (26.0%), Eastern Europe (17.3%), Latin America (16.4%) and Asia (8.3%), with either established cardiovascular disease (78.3%) or with two additional cardiovascular risk factors (21.7%) were randomised to saxagliptin or placebo. Biomarkers of inflammation and insulin resistance were taken at baseline and 2years later in order to correlate saxagliptin effect on cardiovascular outcome to its effect on inflammation and insulin resistance.
Results Mean [+/-standard deviation (SD)] age was 65.0 (+/-8.6)years, 66.9% were male, body mass index was 31.2kg/m(2) (+/-5.6), mean diabetes duration was 11.9years (+/-8.9) and the mean HbA(1c) 8.0% (+/-1.4%). HbA(1c)<7% was most prevalent among North Americans (30.8%) and least among Asians (15.1%), whereas HbA(1c)>9% was 30.7% in Latin America 27.0% in Asia and 15.1% in North America. Diabetic retinopathy was reported in 12.3% of patients, nephropathy in 17.7% and amputation in 2.5%. Diabetic treatments categories were as follows: no medication (5.4%), 1 oral anti-diabetic drug (OAD) (25.0%), 2 OAD (27.7%) and/or insulin (40.9%). The prevalence of micro-albuminuria was twice as high among insulin users compared with users of 2 OAD. Baseline statin use (78.3% overall) varied by region.
Conclusion The SAVOR-TIMI 53 patient population, with differing background diabetes control and anti-diabetic treatment, provides global representation of diabetic patients with established cardiovascular disease or at high risk for cardiovascular disease and is well-positioned to determine the effect of saxagliptin on cardiovascular events.

ID SEXUAL ASSAULT; VETERANS
AB BACKGROUND: More women are using Veterans' Health Administration (VHA) Emergency Departments (EDs), yet VHA ED capacities to meet the needs of women are unknown.
OBJECTIVE: We assessed VHA ED resources and processes for conditions specific to, or more common in, women Veterans.
DESIGN/SUBJECTS: Cross-sectional questionnaire of the census of VHA ED directors
MAIN MEASURES: Resources and processes in place for gynecologic, obstetric, sexual assault and mental health care, as well as patient privacy features, stratified by ED characteristics.
KEY RESULTS: All 120 VHA EDs completed the questionnaire. Approximately nine out of ten EDs reported having gynecologic examination tables within their EDs, 24/7 access to specula, and Gonorrhea/Chlamydia DNA probes. All EDs reported 24/7 access to pregnancy testing. Fewer than two-fifths of EDs reported having radiologist review of pelvic ultrasound images available 24/7; one-third reported having emergent consultations from gynecologists available 24/7. Written transfer policies specific to gynecologic and obstetric emergencies were reported as available in fewer than half of EDs. Most EDs reported having emergency contraception 24/7; however, only approximately half reported having Rho(D) Immunoglobulin available 24/7. Templated triage notes and standing orders relevant to gynecologic conditions were reported as uncommon. Consistent with VHA policy, most EDs reported obtaining care for victims of sexual assault by transferring them to another institution. Most EDs reported having some access to private medical and mental health rooms. Resources and processes were found to be more available in EDs with more encounters by women, more ED staffed beds, and that were located in more complex facilities in metropolitan areas.
CONCLUSIONS: Although most VHA EDs have resources and processes needed for delivering emergency care to women Veterans, some gaps exist. Studies in non-VA EDs are required for comparison. Creative solutions are needed to ensure that women presenting to VHA EDs receive efficient, timely, and consistently high-quality care. (C) Society of General Internal Medicine 2013

AB BACKGROUND: While prior research characterizes women Veterans' barriers to accessing and using Veterans Health Administration (VA) care, there has been little attention to women who access VA and use services, but then discontinue use. Recent data suggest that among women Veterans, there is a 30 % attrition rate within 3 years of initial VA use.
OBJECTIVES: To compare individual characteristics and perceptions about VA care between women Veteran VA attriters (those who discontinue use) and non-attriters (those who continue use), and to compare recent versus remote attriters.
DESIGN: Cross-sectional, population-based 20082009 national telephone survey.
PARTICIPANTS: Six hundred twenty-six attriters and 2,065 non-attriters who responded to the National Survey of Women Veterans.
MAIN MEASURES: Population weighted demographic, military and health characteristics; perceptions about VA healthcare; length of time since last VA use; among attriters, reasons for no longer using VA care.
KEY RESULTS: Fifty-four percent of the weighted VA ever user population reported that they no longer use VA. Forty-five percent of attrition was within the past ten years. Attriters had better overall health (p=0.007), higher income (p<0.001), and were more likely to have health insurance (p<0.001) compared with non-attriters. Attriters had less positive perceptions of VA than non-attriters, with attriters having lower ratings of VA quality and of gender-specific features of VA care (p<0.001). Women Veterans who discontinued VA use since 2001 did not differ from those with more remote VA use on most measures of VA perceptions. Overall, among attriters, distance to VA sites of care and having alternate insurance coverage were the most common reasons for discontinuing VA use.
CONCLUSIONS: We found high VA attrition despite recent advances in VA care for women Veterans. Women's attrition from VA could reduce the critical mass of women Veterans in VA and affect current system-wide efforts to provide high-quality care for women Veterans. An understanding of reasons for attrition can inform organizational efforts to re-engage women who have attrited, to retain current users, and potentially to attract new VA patients.

AB INTRODUCTION: With the increasing number of women Veterans enrolling in the Veterans Health Administration (VA), there is growing demand for reproductive health services. Little is known regarding the on-site availability of reproductive health services at VA and how this varies by site location and type.
OBJECTIVE: To describe the on-site availability of hormonal contraception, intrauterine device (IUD) placement, infertility evaluation or treatment, and prenatal care by site location and type; the characteristics of sites providing these services; and to determine whether, within this context, site location and type is associated with on-site availability of these reproductive health services.
METHODS: We used data from the 2007 Veterans Health Administration Survey of Women Veterans Health Programs and Practices, a national census of VA sites serving 300 or more women Veterans assessing practice structure and provision of care for women. Hierarchical models were used to test whether site location and type (metropolitan hospital-based clinic, non-metropolitan hospital-based clinic, metropolitan community-based outpatient clinic [CBOC]) were associated with availability of IUD placement and infertility evaluation/treatment. Non-metropolitan CBOCs were excluded from this analysis (n=2).
RESULTS: Of 193 sites, 182 (94 %) offered on-site hormonal contraception, 97 (50 %) offered on-site IUD placement, 57 (30 %) offered on-site infertility evaluation/treatment, and 11 (6 %) offered on-site prenatal care. After adjustment, compared with metropolitan hospital based-clinics, metropolitan CBOCs were less likely to offer on-site IUD placement (OR 0.33; 95 % CI 0.14, 0.74).
CONCLUSION: Compared with metropolitan hospital-based clinics, metropolitan CBOCs offer fewer specialized reproductive health services on-site. Additional research is needed regarding delivery of specialized reproductive health care services for women Veterans in CBOCs and clinics in non-metropolitan areas.

AB Relative to the general population, lesbian and bisexual (LB) women are overrepresented in the military and are significantly more likely to have a history of military service compared to all adult women. Due to institutional policies and stigma associated with a gay or lesbian identity, very little empirical research has been done on this group of women veterans. Available data suggest that compared to heterosexual women veterans, LB women veterans are likely to experience heightened levels of prejudice and discrimination, victimization, including greater incidence of rape, as well as adverse health and substance use disorders. They are also likely to encounter a host of unique issues when accessing health care, including fears of insensitive care and difficulty disclosing sexual orientation to Veterans Health Administration (VHA) providers. Training of staff and providers, education efforts, outreach activities, and research on this subpopulation are critical to ensure equitable and high quality service delivery.

AB BACKGROUND: Obesity is a growing public health concern and is becoming an epidemic among veterans in the post-deployment period.
OBJECTIVE: To explore the relationship between body mass index (BMI) and posttraumatic stress disorder (PTSD) in a large cohort of Iraq and Afghanistan veterans, and to evaluate trajectories of change in BMI over 3 years.
DESIGN: Retrospective, longitudinal cohort analysis of veterans' health records
PARTICIPANTS: A total of 496,722 veterans (59,790 female and 436,932 male veterans) whose height and weight were recorded at the Department of Veterans Affairs (VA) healthcare system at least once after the end of their last deployment and whose first post-deployment outpatient encounter at the VA was at least 1 year prior to the end of the study period (December 31, 2011).
MAIN MEASURES: BMI, mental health diagnoses.
KEY RESULTS: Seventy-five percent of Iraq and Afghanistan veterans were either overweight or obese at baseline. Four trajectories were observed: "stable overweight" represented the largest class; followed by "stable obese;" "overweight/obese gaining;" and "obese losing." During the 3-year ascertainment period, those with PTSD and depression in particular were at the greatest risk of being either obese without weight loss or overweight or obese and continuing to gain weight. Adjustment for demographics and antipsychotic medication attenuated the relationship between BMI and certain mental health diagnoses. Although BMI trajectories were similar in men and women, some gender differences were observed. For example, the risk of being in the persistently obese class in men was highest for those with PTSD, whereas for women, the risk was highest among those with depression.
CONCLUSIONS: The growing number of overweight or obese returning veterans is a concerning problem for clinicians who work with these patients. Successful intervention to reduce the prevalence of obesity will require integrated efforts from primary care and mental health to treat underlying mental health causes and assist with engagement in weight loss programs.

AB BACKGROUND: Many lesbian and bisexual (LB) women veterans may have been targets of victimization in the military based on their gender and presumed sexual orientation, and yet little is known regarding the health or mental health of LB veterans, nor the degree to which they feel comfortable receiving care in the VA.
OBJECTIVE: The purpose of this study was to examine the prevalence of mental health and gender-specific conditions, VA healthcare satisfaction and trauma exposure among LB veterans receiving VA care compared with heterosexually-identified women veterans receiving.
DESIGN: Prospective cohort study of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) women veterans at two large VA facilities.
PARTICIPANTS: Three hundred and sixty five women veterans that completed a baseline survey. Thirty-five veterans (9.6 %) identified as gay or lesbian (4.7 %), or bisexual (4.9 %).
MAIN MEASURES: Measures included sexual orientation, military sexual trauma, mental and gender-specific health diagnoses, and VA healthcare utilization and satisfaction.
KEY RESULTS: LB OEF/OIF veterans were significantly more likely to have experienced both military and childhood sexual trauma than heterosexual women (MST: 31 % vs. 13 %, p<.001; childhood sexual trauma: 60 % vs. 36 %, p=.01), to be hazardous drinkers (32 % vs. 16 %, p=.03) and rate their current mental health as worse than before deployment (35 % vs. 16 %, p<.001).
CONCLUSIONS: Many LB veterans have experienced sexual victimization, both within the military and as children, and struggle with substance abuse and poor mental health. Health care providers working with female Veterans should be aware of high rates of military sexual trauma and childhood abuse and refer women to appropriate VA treatment and support groups for sequelae of these experiences. Future research should focus on expanding this study to include a larger and more diverse sample of lesbian, gay, bisexual, and transgender veterans receiving care at VA facilities across the country.

DT Article
DE cardiovascular disease; risk factors; race; ethnicity; women veterans
ID QUALITY-OF-CARE; SMOKING; DISEASE; UPDATE; SYSTEM
AB BACKGROUND: Heart disease is the leading cause of death for women in the United States, accounting for 24.5 % of all deaths among women. Earlier research has demonstrated racial/ethnic differences in prevalence of cardiovascular (CVD) risk factors.
OBJECTIVE: To empirically examine the prevalence of CVD risk factors among a national sample of women Veterans by race/ethnicity, providing the first portrait of women Veterans' cardiovascular care needs.
DESIGN AND PARTICIPANTS: Cross-sectional, national population-based telephone survey of 3,611 women Veterans.
MEASUREMENTS: Women Veterans were queried about presence of diabetes, hypertension, obesity, tobacco use and physical activity. Four racial/ethnic categories were created: Hispanic, Non-Hispanic White (White), Non-Hispanic Black (Black), and Other. Logistic regressions were conducted for each risk factor to test for racial/ethnic differences, controlling for age (under 40 vs. 40 and over).
KEY RESULTS: Racial/ethnic differences in CVD risk factors persisted after adjusting for age. Black women Veterans were more likely to report a diagnosis of diabetes (OR: 2.58, 95 % CI: 1.07, 6.21) or hypertension (OR: 2.31, 95 % CI: 1.10, 4.83) and be obese (OR: 2.06, 95 % CI: 1.05, 3.91) than White women Veterans. Hispanic women Veterans were more likely than White women Veterans to report diabetes (OR: 4.20, 95 % CI: 1.15, 15.39) and daily smoking (OR: 3.38, 95 % CI: 1.01, 11.30), but less likely to report a hypertension diagnosis (OR 0.21, 95% CI: 0.07, 0.64) or to be obese (OR: 0.39, 95 % CI: 0.18, 0.81).
CONCLUSIONS: Among women Veterans, CVD risks vary by race/ethnicity. Black women Veterans consistently face higher CVD risk compared to White women Veterans, while results are mixed for Hispanic women Veterans. (C) Society of General Internal Medicine 2013

EXPERIENCES
AB BACKGROUND: The changing scope of women's roles in combat operations has led to growing interest in women's deployment experiences and post-deployment adjustment.
OBJECTIVES: To quantify the gender-specific frequency of deployment stressors, including sexual and nonsexual harassment, lack of social support and combat exposure. To quantify gender-specific post-deployment mental health conditions and associations between deployment stressors and posttraumatic stress disorder (PTSD), to inform the care of Veterans returning from the current conflicts.
DESIGN: National mail survey of OEF/OIF Veterans randomly sampled within gender, with women over-sampled.
SETTING: The community.
PARTICIPANTS: In total, 1,207 female and 1,137 male Veterans from a roster of all Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans. Response rate was 48.6 %.
MAIN MEASURES: Deployment stressors (including combat and harassment stress), PTSD, depression, anxiety and alcohol use, all measured via self-report.
KEY RESULTS: Women were more likely to report sexual harassment (OR=8.7, 95% CI: 6.9, 11) but less likely to report combat (OR= 0.62, 95 % CI: 0.50, 0.76). Women and men were equally likely to report symptoms consistent with probable PTSD (OR = 0.87, 95 % CI: 0.70, 1.1) and symptomatic anxiety (OR = 1.1, 9 5% CI: 0.86, 1.3). Women were more likely to report probable depression (OR= 1.3, 95 % CI: 1.1, 1.6) and less likely to report problematic alcohol use (OR = 0.59, 9 5% CI: 0.47, 0.72). With a five-point change in harassment stress, adjusted odds ratios for PTSD were 1.36 (95 % CI: 1.23, 1.52) for women and 1.38 (95 % CI: 1.19, 1.61) for men. The analogous associations between combat stress and PTSD were 1.31 (95 % CI: 1.24, 1.39) and 1.31 (95 % CI: 1.26, 1.36), respectively.
CONCLUSIONS: Although there are important gender differences in deployment stressors-including women's increased risk of interpersonal stressors- and post-deployment adjustment, there are also significant similarities. The post-deployment adjustment of our nation's growing population of female Veterans seems comparable to that of our nation's male Veterans. (C) Society of General Internal Medicine 2013

TI Women Veterans' Healthcare Delivery Preferences and Use by Military
Service Era: Findings from the National Survey of Women Veterans
SO JOURNAL OF GENERAL INTERNAL MEDICINE

utilization; health care preferences
ID GENDER-DIFFERENCES; VA; ILLNESS
AB BACKGROUND: The number of women Veterans (WVs) utilizing the Veterans Health Administration (VA) has doubled over the past decade, heightening the importance of understanding their healthcare delivery preferences and utilization patterns. Other studies have identified healthcare issues and behaviors of WVs in specific military service eras (e. g., Vietnam), but delivery preferences and utilization have not been examined within and across eras on a population basis.
OBJECTIVE: To identify healthcare delivery preferences and healthcare use of WVs by military service era to inform program design and patient-centeredness.
DESIGN AND PARTICIPANTS: Cross-sectional 2008-2009 survey of a nationally representative sample of 3,611 WVs, weighted to the population.
MAIN MEASURES: Healthcare delivery preferences measured as importance of selected healthcare features; types of healthcare services and number of visits used; use of VA or non-VA; all by military service era.
KEY RESULTS: Military service era differences were present in types of healthcare used, with World War II and Korea era WVs using more specialty care, and Vietnam era-to-present WVs using more women's health and mental health care. Operations Enduring Freedom, Iraqi Freedom, New Dawn (OEF/OIF/OND) WVs made more healthcare visits than WVs of earlier military eras. The greatest healthcare delivery concerns were location convenience for Vietnam and earlier WVs, and cost for Gulf War 1 and OEF/OIF/OND WVs. Co-located gynecology with general healthcare was also rated important by a sizable proportion of WVs from all military service eras.
CONCLUSIONS: Our findings point to the importance of ensuring access to specialty services closer to home for WVs, which may require technology-supported care. Younger WVs' higher mental health care use reinforces the need for integration and coordination of primary care, reproductive health and mental health care.

TI Self-Reported Stressors of National Guard Women Veterans Before and
After Deployment: The Relevance of Interpersonal Relationships
SO JOURNAL OF GENERAL INTERNAL MEDICINE
LA English
DT Article
DE women's health; veterans; survey research; quality of life
ID MILITARY SEXUAL TRAUMA; COMBAT; WAR; CARE; RISK; IRAQ
AB BACKGROUND: With their rapidly expanding roles in the military, women service members experience significant stressors throughout their deployment experience. However, there are few studies that examine changes in women Veterans' stressors before and after deployment.
OBJECTIVE: This study examines the types of stressors women Veterans report before deployment, immediately after deployment, 3 months after deployment, and 1 year post-deployment.
DESIGN: Descriptive data on reported stressors was collected at four time points of a longitudinal study (HEROES Project). Open-ended responses from the Coping Response Inventory (CRI) were coded into six possible major stressor categories for analysis.
PARTICIPANTS: Seventy-nine Army National Guard and Reserve female personnel deploying to Operation Enduring Freedom (OFF)/Operation Iraqi Freedom (OIF) were surveyed prior to deployment. Of these participants, 35 women completed Phase 2, 41 completed Phase 3, and 48 completed Phase 4 of the study.
KEY RESULTS: We identified six major stressor categories: (1) interpersonal (i.e., issues with family and/or friends), (2) deployment-related and military-related, (3) health concerns, (4) death of a loved one, (5) daily needs (i. e., financial/housing/transportation concerns), and (6) employment or school-related concerns. At all time points, interpersonal issues were one of the most common type of stressor for this sample. Daily needs concerns increased from 3 months post-deployment to 1 year post-deployment.
CONCLUSIONS: Interpersonal concerns are commonly reported by women Veterans both before and after their combat experience, suggesting that this is a time during which interpersonal support is especially critical. We discuss implications, which include the need for a more coordinated approach to women Veterans' health care (e. g., greater community-based outreach), and the need for more and more accessible Veterans Affairs (VA) services to address the needs of female Veterans.

TI Measuring stimulus-frequency otoacoustic emissions using swept tones
SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
ID COHERENT REFLECTION; HUMANS; MECHANICS; DELAYS; LEVEL; EARS
AB Although stimulus-frequency otoacoustic emissions (SFOAEs) offer compelling advantages as noninvasive probes of cochlear function, they remain underutilized compared to other evoked emission types, such as distortion-products (DPOAEs), whose measurement methods are less complex and time-consuming. Motivated by similar advances in the measurement of DPOAEs, this paper develops and characterizes a more efficient SFOAE measurement paradigm based on swept tones. In contrast to standard SFOAE measurement methods, in which the emissions are measured in the sinusoidal steady-state using discrete tones of well defined frequency, the swept-tone method sweeps rapidly across frequency (typically at rates of 1 Hz/ms or greater) using a chirp-like stimulus. Measurements obtained using both swept-and discrete-tone methods in an interleaved suppression paradigm demonstrate that the two methods of measuring SFOAEs yield nearly equivalent results, the differences between them being comparable to the run-to-run variability encountered using either method alone. The match appears robust to variations in measurement parameters, such as sweep rate and direction. The near equivalence of the SFOAEs obtained using the two measurement methods enables the interpretation of swept-tone SFOAEs within existing theoretical frameworks. Furthermore, the data demonstrate that SFOAE phase-gradient delays-including their large and irregular fluctuations across frequency-reflect actual physical time delays at different frequencies, showing that the physical emission latency, not merely the phase gradient, is inherently irregular.

TI The CD225 Domain of IFITM3 Is Required for both IFITM Protein
Association and Inhibition of Influenza A Virus and Dengue Virus
Replication
SO JOURNAL OF VIROLOGY

INFECTION; IDENTIFICATION; RESISTANCE; FUSION; FORCES
AB The interferon-induced transmembrane protein 3 (IFITM3) gene is an interferon-stimulated gene that inhibits the replication of multiple pathogenic viruses in vitro and in vivo. IFITM3 is a member of a large protein superfamily, whose members share a functionally undefined area of high amino acid conservation, the CD225 domain. We performed mutational analyses of IFITM3 and identified multiple residues within the CD225 domain, consisting of the first intramembrane domain (intramembrane domain 1 [IM1]) and a conserved intracellular loop (CIL), that are required for restriction of both influenza A virus (IAV) and dengue virus (DENV) infection in vitro. Two phenylalanines within IM1 (F75 and F78) also mediate a physical association between IFITM proteins, and the loss of this interaction decreases IFITM3-mediated restriction. By extension, similar IM1-mediated associations may contribute to the functions of additional members of the CD225 domain family. IFITM3's distal N-terminal domain is also needed for full antiviral activity, including a tyrosine (Y20), whose alteration results in mislocalization of a portion of IFITM3 to the cell periphery and surface. Comparative analyses demonstrate that similar molecular determinants are needed for IFITM3's restriction of both IAV and DENV. However, a portion of the CIL including Y99 and R87 is preferentially needed for inhibition of the orthomyxovirus. Several IFITM3 proteins engineered with rare single-nucleotide polymorphisms demonstrated reduced expression or mislocalization, and these events were associated with enhanced viral replication in vitro, suggesting that possessing such alleles may impact an individual's risk for viral infection. On the basis of this and other data, we propose a model for IFITM3-mediated restriction.

AB Expertly collected, well-curated data sets consisting of comprehensive clinical characterization and raw structural, functional and diffusion-weighted DICOM images in schizophrenia patients and sex and age-matched controls are now accessible to the scientific community through an on-line data repository (coins.mrn.org). The Mental Illness and Neuroscience Discovery Institute, now the Mind Research Network (MRN, http://www.mrn.org/), comprised of investigators at the University of New Mexico, the University of Minnesota, Massachusetts General Hospital, and the University of Iowa, conducted a cross-sectional study to identify quantitative neuroimaging biomarkers of schizophrenia. Data acquisition across multiple sites permitted the integration and cross-validation of clinical, cognitive, morphometric, and functional neuroimaging results gathered from unique samples of schizophrenia patients and controls using a common protocol across sites. Particular effort was made to recruit patients early in the course of their illness, at the onset of their symptoms. There is a relatively even sampling of illness duration in chronic patients. This data repository will be useful to 1) scientists who can study schizophrenia by further analysis of this cohort and/or by pooling with other data; 2) computer scientists and software algorithm developers for testing and validating novel registration, segmentation, and other analysis software; and 3) educators in the fields of neuroimaging, medical image analysis and medical imaging informatics who need exemplar data sets for courses and workshops. Sharing provides the opportunity for independent replication of already published results from this data set and novel exploration. This manuscript describes the inclusion/exclusion criteria, imaging parameters and other information that will assist those wishing to use this data repository.

AB Recent studies showed that Ten-eleven translocation (Tet) family dioxygenases can oxidize 5-methyl-2'-deoxycytidine (5-mdC) in DNA to yield the 5-hydroxymethyl, 5-formyl and 5-carboxyl derivatives of 2'-deoxycytidine (5-HmdC, 5-FodC and 5-CadC). 5-HmdC in DNA may be enzymatically deaminated to yield 5-hydroxymethyl-2'-deoxyuridine (5-HmdU). After their formation at CpG dinucleotide sites, these oxidized pyrimidine nucleosides, particularly 5-FodC, 5-CadC, and 5-HmdU, may be cleaved from DNA by thymine DNA glycosylase, and subsequent action of base-excision repair machinery restores unmethylated cytosine. These processes are proposed to be important in active DNA cytosine demethylation in mammals. Here we used a reversed-phase HPLC coupled with tandem mass spectrometry (LC-MS/MS/MS) method, along with the use of stable isotope-labeled standards, for accurate measurements of 5-HmdC, 5-FodC, 5-CadC and 5-HmdU in genomic DNA of cultured human cells and multiple mammalian tissues. We found that overexpression of the catalytic domain of human Tet1 led to marked increases in the levels of 5-HmdC, 5-FodC and 5-CadC, but only a modest increase in 5-HmdU, in genomic DNA of HEK293T cells. Moreover, 5-HmdC is present at a level that is approximately 2-3 and 3-4 orders of magnitude greater than 5-FodC and 5-CadC, respectively, and 35-400 times greater than 5-HmdU in the mouse brain and skin, and human brain. The robust analytical method built a solid foundation for dissecting the molecular mechanisms of active cytosine demethylation, for measuring these 5-mdC derivatives and assessing their involvement in epigenetic regulation in other organisms and for examining whether these 5-mdC derivatives can be used as biomarkers for human diseases.

AB This research explores health care professionals' understanding of the problems that arise in managing a terminal condition impacting the Latino population and conceptualizes the components of patient advocacy that address gaps in end-of-life care for patients and their family members. Limited research exists regarding patient advocacy from the perspectives of health care providers working with vulnerable Latino populations utilizing a public sector health care system. Forty-six semi-structured interviews were conducted with providers from different disciplines including medicine, nursing, social work, and chaplaincy. Although roles and responsibilities vary among health providers, it is imperative that all providers become aware of the need for patient advocacy. Doing so is not only in the best interest of vulnerable Latino populations but also has overarching financial benefits and positive outcomes for patients, administrators, and public health care systems. Social workers are the ideal professionals to assume leadership roles and share their knowledge of how to advocate effectively for the most vulnerable populations.

AB .Background: An association between impulsivity and smoking has been consistently reported in the literature, but few studies have examined how distinct dimensions of impulsivity may relate differentially to smoking initiation versus persistent smoking. The aim of the current study was to examine the relationship between self-report and behavioral measures of impulsivity and smoking status in college students. Methods: Participants (N = 243) completed a self-report history of tobacco use, 2 self-report measures of impulsivity (the Barratt Impulsiveness Scale and Zuckerman Sensation-Seeking Scale), and 2 behavioral measures (the Delay Discounting Task and Iowa Gambling Task). All participants were classified as never-smokers, triers, or smokers based on their smoking history, and between-group differences on the 4 measures were examined. Results: On the self-report measures, all 3 groups differed on sensation seeking, with the never-smokers reporting the lowest levels and the smokers reporting the highest. Furthermore, the smokers reported significantly higher disinhibitory impulsivity than the triers and never-smokers. The groups did not differ on the behavioral measures. Conclusions: These results indicate that distinct dimensions of impulsivity characterize different smoking phenotypes. In particular, sensation seeking is associated with the initiation of smoking, whereas disinhibitory impulsivity is associated with the transition to more persistent and regular use of cigarettes.

AB To understand the functional role of specific neurons in micro- and macro-brain circuitry, health, and disease, it is critical to control their activity precisely. This ambitious goal was first achieved by optogenetics, allowing researchers to increase or decrease neural activity artificially with high temporal and spatial precision. In contrast to the revolution optogenetics engendered in invertebrate and rodent research, only a few studies have reported optogenetic-induced neuronal and behavioral effects in primates. Such studies are nonetheless critical before optogenetics can be applied in a clinical setting. Here, we review the state-of-the-art tools for performing optogenetics in mammals, emphasizing recent neuronal and behavioral results obtained in nonhuman primates.

AB Thoracic aortic endografting has been successfully implemented to treat aneurysmal disease of the distal aortic arch and descending thoracic aorta. Although there are reports of ascending aortic endovascular interventions, the total endovascular repair of a ruptured ascending aorta secondary to a Type A dissection has not been described. We report the case of a 77-year-old patient who presented with a ruptured ascending aortic aneurysm secondary to degeneration of a Stanford type A aortic dissection. His surgical history was significant for orthotropic heart transplant 19 years prior. The dissection, aneurysm, and rupture occurred in the native aorta distal to the ascending aortic suture line. At presentation, he was hemodynamically unstable with a right hemothorax. We placed 3 Medtronic Talent Thoracic Stent Graft devices (Medtronic Inc, Minneapolis, MN) across the suture line in the ascending aorta, excluding the rupture. The patient survived and has been followed to 25 months.

AB Inferior vena cava (IVC) filter placement has seen a rising trend over the past decade. Although effective in the prevention of future pulmonary emboli, filters are associated with several long-term complications including deep venous thrombosis, filter migration, filter fracture, and caval thrombosis. The IVC filters have evolved over the years to minimize these unwarranted sequelae. We describe a technique to remove a permanent IVC filter in a patient who no longer required mechanical protection.

AB OBJECTIVE: Family practices around weight-related behaviors can shape children's development of disordered weight control behaviors (DWCB), such as vomiting, taking laxatives, or taking diet pills without a prescription. This study examined family meal and physical activity (PA) practices associated with DWCB among a multiethnic sample of youth.
METHODS: We assessed self-report data on frequency of family sit-down dinners, types of parental involvement in their children's PA, and DWCB are from 15,461 6th to 8th grade girls and boys in 47 middle schools participating in the Massachusetts Healthy Choices Study at baseline (2005).
RESULTS: Youth who had family sit-down dinners every day had lower odds of DWCB (girls: odds ratio [OR] 0.3; 95% confidence interval [CI] 0.2-0.5; boys: OR 0.6; 95% CI 0.4-0.9) than youth who never had family sit-down dinners. Similar effect estimates were found for youth who had family sit-down dinners most days. Parental provision of rides to and from a PA event was also found to be protective against DWCB among girls (OR 0.7; 95% Cl 0.5-0.9). In contrast, parental participation in PA with their children was associated with increased risk for DWCB (girls: OR 1.4; 95% CI 1.0-1.8; boys: OR 1.9; 95% CI 1.4-2.4). These associations did not differ by race/ethnicity or weight status.
CONCLUSIONS: Programs emphasizing the importance of family meals may be beneficial in preventing DWCB in youth of all ethnicities. Further research is needed on how various methods of parental involvement in their children's PA are associated with DWCB.

AB Traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) are signature injuries of the wars in Iraq and Afghanistan and have been linked to an increased risk of Alzheimer's disease (AD) and other dementias. A meeting hosted by the Alzheimer's Association and the Veterans' Health Research Institute (NCIRE) in May 2012 brought together experts from the U.S. military and academic medical centers around the world to discuss current evidence and hypotheses regarding the pathophysiological mechanisms linking TBI, PTSD, and AD. Studies underway in civilian and military populations were highlighted, along with new research initiatives such as a study to extend the Alzheimer's Disease Neuroimaging Initiative (ADNI) to a population of veterans exposed to TBI and PTSD. Greater collaboration and data sharing among diverse research groups is needed to advance an understanding and appropriate interventions in this continuum of military injuries and neurodegenerative disease in the aging veteran.

AB Posterior cortical atrophy (PCA) is a clinicoradiologic syndrome characterized by progressive decline in visual processing skills, relatively intact memory and language in the early stages, and atrophy of posterior brain regions. Misdiagnosis of PCA is common, owing not only to its relative rarity and unusual and variable presentation, but also because patients frequently first seek the opinion of an ophthalmologist, who may note normal eye examinations by their usual tests but may not appreciate cortical brain dysfunction. Seeking to raise awareness of the disease, stimulate research, and promote collaboration, a multidisciplinary group of PCA research clinicians formed an international working party, which had its first face-to-face meeting on July 13, 2012 in Vancouver, Canada, prior to the Alzheimer's Association International Conference.

AB We have shown that oxidative stress is a mechanism of free fatty acid (FFA)-induced beta-cell dysfunction. Unsaturated fatty acids in membranes, including plasma and mitochondrial membranes, are substrates for lipid peroxidation, and lipid peroxidation products are known to cause impaired insulin secretion. Therefore, we hypothesized that mice overexpressing glutathione peroxidase-4 (GPx4), an enzyme that specifically reduces lipid peroxides, are protected from fat-induced beta-cell dysfunction. GPx4-overexpressing mice and their wild-type littermate controls were infused intravenously with saline or oleate for 48 h, after which reactive oxygen species (ROS) were imaged, using dihydrodichlorofluorescein diacetate in isolated islets, and beta-cell function was assessed ex vivo in isolated islets and in vivo during hyperglycemic clamps. Forty-eight-hour FFA elevation in wild-type mice increased ROS and the lipid peroxidation product malondialdehyde and impaired beta-cell function ex vivo in isolated islets and in vivo, as assessed by decreased disposition index. Also, islets of wild-type mice exposed to oleate for 48 h had increased ROS and lipid peroxides and decreased beta-cell function. In contrast, GPx4-overexpressing mice showed no FFA-induced increase in ROS and lipid peroxidation and were protected from the FFA-induced impairment of beta-cell function assessed in vitro, ex vivo and in vivo. These results implicate lipid peroxidation in FFA-induced beta-cell dysfunction.

GENE-EXPRESSION
AB Myocardial stretch is an established signal that leads to hypertrophy. Myocardial stretch induces a first immediate force increase followed by a slow force response (SFR), which is a consequence of an increased Ca2+ transient that follows the NHE1 Na+/H+ exchanger activation. Carbonic anhydrase II (CAII) binds to the extreme COOH terminus of NHE1 and regulates its transport activity. We aimed to test the role of CAII bound to NHE1 in the SFR. The SFR and changes in intracellular pH (pH(i)) were evaluated in rat papillary muscle bathed with CO2/HCO3- buffer and stretched from 92% to 98% of the muscle maximal force development length for 10 min in the presence of the CA inhibitor 6-ethoxzolamide (ETZ, 100 mu M). SFR control was 120 +/- 3% (n = 8) of the rapid initial phase and was fully blocked by ETZ (99 +/- 4%, n = 6). The SFR corresponded to a maximal increase in pH(i) of 0.18 +/- 0.02 pH units (n = 4), and pH(i) changes were blocked by ETZ (0.04 +/- 0.04, n = 6), as monitored by epifluorescence. NHE1/CAII physical association was examined in the SFR by coimmunoprecipitation, using muscle lysates. CAII immunoprecipitated with an anti-NHE1 antibody and the CAII immunoprecipitated protein levels increased 58 +/- 9% (n = 6) upon stretch of muscles, assessed by immunoblots. The p90(RSK) kinase inhibitor SL0101-1 (10 mu M) blocked the SFR of heart muscles after stretch 102 +/- 2% (n = 4) and reduced the binding of CAII to NHE1, suggesting that the stretch-induced phosphorylation of NHE1 increases its binding to CAII. CAII/NHE1 interaction constitutes a component of the SFR to heart muscle stretch, which potentiates NHE1-mediated H+ transport in the myocardium.

AB OBJECTIVE. IgG4-related disease was not recognized as a specific clinical entity until 2003 when extrapancreatic lesions were reported in patients with autoimmune pancreatitis. IgG4-related disease is characterized by elevated serum IgG4 levels and infiltration of the target organ by IgG4-positive plasma cells. The complete gamut of visceral involvement is still being outlined. The purpose of this article is to highlight the plethora of lesions under the spectrum of IgG4-related disease of the abdomen and pelvis, describe their imaging appearances on multimodality cross-sectional imaging, and discuss the differential diagnoses.
CONCLUSION. It is important for radiologists to recognize the multiorgan involvement and few classic features of IgG4-related disease that often tend to simulate malignancy.

AB OBJECTIVE. CT dose reduction has become a top priority for many radiology practices as a result of federal and state initiatives and public concern. Implementing this in practice, however, is difficult because of the variability between practices, CT scanners, radiologist preferences, and institutional capacity.
CONCLUSION. This article will discuss strategies for successful CT dose reduction instituted in multivendor practices.

AB OBJECTIVE. CT colonography (CTC) has been fully validated as an accurate screening test for colorectal carcinoma and is being disseminated globally. There is an abundance of new literature addressing the prior concerns of the U. S. Preventive Services Task Force and the Centers for Medicare & Medicaid Services. Specific areas related to radiation dose, extracolonic findings, and generalizability of CTC to senior patients are discussed.
CONCLUSION. The time has arrived for national reimbursement of CTC in the United States.

AB OBJECTIVE. Ultrasmall superparamagnetic iron oxide nanoparticles, such as ferumoxytol, produce decreased MR signal on susceptibility-inducing T2*-weighted sequences in tissues of the reticuloendothelial system. However, acute iron deposition in the adrenals has not been reported. The purpose of this article is to report our initial observations of the imaging behavior of the normal adrenals on ferumoxytol-enhanced T2*-weighted magnetic resonance imaging.
SUBJECTS AND METHODS. Quantitative T2* imaging was performed at 3 T using a breath-hold monopolar multiecho gradient echo sequence with six equally spaced in-phase echoes in nine patients. Changes in signal-to-noise ratio (SNR) were analyzed prior to and 48 hours after ferumoxytol administration in the adrenals, liver and spleen (positive controls), and pancreas and skeletal muscle (negative controls).
RESULTS. In comparison with unenhanced images, there was an average SNR decrease of 67.4% in the right adrenal, 77.6% in the left adrenal, 68.4% in the liver, 89.1% in the spleen, 15.0% in the pancreas, and 9.5% in skeletal muscle on T2*-weighted images obtained 48 hours after ferumoxytol administration. The decrease in SNR observed in the adrenals was significantly greater than that seen in the pancreas and skeletal muscle (left adrenal, p < 0.0001; right adrenal, p = 0.0002) and similar to that seen in the liver and spleen.
CONCLUSION. The normal adrenal loses signal on ferumoxytol-enhanced T2*-weighted MRI. Acute iron deposition within the adrenals has not been previously described. The mechanism of ferumoxytol uptake in the adrenal and potential clinical applications warrant further investigation.

AB OBJECTIVE. The purpose of this article is to describe the advantages and diagnostic and prognostic implications of imaging in the management of vulvar carcinoma.
CONCLUSION. As the treatment of vulvar carcinoma evolves to tailored surgery and chemoradiation therapy to reduce morbidity, the importance of pretreatment assessment of vulvar carcinoma increases. Advances in imaging, such as pelvic MRI and PET, add to the benefits of clinical evaluation in pretreatment planning, assessment of response to chemoradiation therapy, and posttreatment surveillance.

AB OBJECTIVE. The purpose of this article is to describe the image acquisition, identification, and reporting of postoperative adhesions in patients undergoing CT for "redo sternotomy" surgical planning.
CONCLUSION. Adhesions appear as linear fibrous bands that join structures in the mediastinum viewed on static images. Confirmation by cine imaging shows deformation of mediastinal structures. Identification and reporting of adhesions will likely guide surgeons to safer interventions.

AB OBJECTIVE. Older legacy bariatric surgical procedures, including jejunocolic bypass, jejunoileal bypass, vertical banded gastroplasty, and biliopancreatic diversion, are no longer performed. Biliopancreatic diversion with duodenal switch is still performed in select centers. Although the legacy procedures are no longer performed, there are still patients who have undergone these surgeries in the past who are currently either under continuous surveillance or are being evaluated for surgical conversion or revision because of complications or weight regain. The purpose of this article is to describe the evolutionary development of various bariatric surgical techniques and the associated surgical anatomy. Because these procedures are no longer performed, only limited imaging of legacy bariatric surgeries is available for radiologic demonstration.
CONCLUSION. Although earlier bariatric surgical techniques are no longer favored, there are still patients who underwent these procedures who require imaging evaluation for clinical follow-up or surgical revision. Understanding the radiologic-surgical anatomy of these older bariatric procedures can help in the prompt and appropriate management of these patients.

AB OBJECTIVE. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 has been rapidly accepted in clinical trials as a standard measure to assess tumor response to therapy and is expected to improve response assessment, especially in genomically defined patients. The impact of RECIST 1.1 was compared with RECIST 1.0 in non-small cell lung cancer (NSCLC) patients with sensitizing epidermal growth factor receptor (EGFR) mutations treated with EGFR tyrosine kinase inhibitors.
MATERIALS AND METHODS. Seventy patients with advanced NSCLC harboring sensitizing EGFR mutations treated with a first-line EGFR tyrosine kinase inhibitor were retrospectively studied. Tumor measurements and response assessment were performed using RECIST 1.0 and RECIST 1.1. The number of target lesions, the percentage change at the initial follow-up, best response, and time to progression were compared between RECIST 1.1 and RECIST 1.0.
RESULTS. The number of target lesions identified using RECIST 1.1 was significantly lower compared with that using RECIST 1.0 (mean, 2.7 and 2.0, respectively; p < 0.0001; paired Student t test), with a decrease in 31 patients (44%). The initial proportional changes of the target lesion measurements had high correlation between the two criteria (R-2 = 0.8070), with concordant response assessment in 66 patients (94%). The best response showed almost perfect agreement (kappa(w) = 0.970). Time to progression (TTP) did not differ between the two criteria in 52 patients (74%), was longer by RECIST 1.1 in 15 patients (21%), and was shorter by RECIST 1.1 in three patients (4%).
CONCLUSION. RECIST 1.1 provided highly concordant response assessment with a decreased number of target lesions compared with RECIST 1.0 in advanced NSCLC patients harboring sensitizing EGFR mutations treated with an EGFR tyrosine kinase inhibitor. RECIST 1.1 altered TTP in 25% of patients compared with RECIST 1.0.

AB OBJECTIVE. The liver is one of the most common sites of metastatic disease. The increasing use of molecular targeted therapy, including antiangiogenic agents, mammalian target of rapamycin inhibitors, and various monoclonal antibodies, for the treatment of various carcinomas and sarcomas has rendered use of simple size measurements for the assessment of treatment response inadequate. Several atypical patterns of treatment response, at times mimicking tumor progression, are increasingly seen, leading to confusion. The purpose of this article is to familiarize the reader with the unusual patterns in which liver metastases respond to molecular targeted therapy and help differentiate treatment response mimicking progression (pseudoprogression) from true progression.
CONCLUSION. In the era of molecular targeted therapy, every radiologist who interprets oncologic studies needs to be aware of the unusual patterns of treatment response and should be able to differentiate pseudoprogression of liver metastases from true progression because this distinction has an important impact on clinical management.

AB Background: Although ECG left ventricular hypertrophy (LVH) by Cornell product (CP) predicts increased mortality in patients with ischemic cardiomyopathy (ICM), those without CP LVH remain at relatively high risk. We examined whether T-wave alternans (TWA) testing and ST depression can improve risk stratification in these patients.
Methods and Results: This study examined 317 patients with ICM, nonsustained ventricular tachycardia, and a resting ECG in sinus rhythm, who presented for electrophysiology and TWA testing, and potential implantable cardioverter defibrillator (ICD) implantation. LVH was defined by CP :[(R-aVL + S-V3) + 6 mm in women] x QRS duration > 2440 mm * msec. ST depression was examined as a categorical variable using an established threshold of depression of >= 50 mu V in V-5 or V-6. In Cox multivariate models, abnormal TWA testing and ST depression were independent predictors of mortality in patients without CP LVH (HR 2.52, CI 1.09-5.80, P = 0.030 and HR 2.87, CI 1.41-5.81, P = 0.004, respectively). Individuals with no LVH by CP, normal TWA, and no significant ST depression, comprised 23% of the study population and had a 5.6% 3-year mortality, compared to an overall 20% mortality.
Conclusions: TWA and ST depression testing are strong predictors of mortality among ICM patients without CP LVH, with normal testing conversely predicting low 3-year mortality. Thus, risk assessment with TWA testing and a resting ECG can identify ICM patients at low risk who may be less likely to benefit from ICD implantation.

AB Background: We evaluated AGS-1C4D4, a fully human monoclonal antibody to prostate stem cell antigen (PSCA), with gemcitabine in a randomized, phase II study of metastatic pancreatic cancer.
Patients and methods: Patients with Eastern Cooperative Oncology Group (ECOG) performance status 0/1 and previously untreated, metastatic pancreatic adenocarcinoma were randomly assigned 1:2 to gemcitabine (1000 mg/m(2) weekly seven times, 1 week rest, weekly three times q4weeks) or gemcitabine plus AGS-1C4D4 (48 mg/kg loading dose, then 24 mg/kg q3weeks IV). The primary end point was 6-month survival rate (SR). Archived tumor samples were collected for pre-planned analyses by PSCA expression.
Results: Between April 2009 and May 2010, 196 patients were randomly assigned to gemcitabine (n = 63) or gemcitabine plus AGS-1C4D4 (n = 133). The 6-month SR was 44.4% (95% Cl, 31.9-57.5) in the gemcitabine arm and 60.9% (95% Cl, 52.1-69.2) in the gemcitabine plus AGS-1C4D4 arm (P = 0.03), while the median survival was 5.5 versus 7.6 months and the response rate was 13.1% versus 21.6% in the two arms, respectively. The 6-month SR was 57.1% in the gemcitabine arm versus 79.5% in the gemcitabine plus AGS-1C4D4 arm among the PSCA-positive subgroup and 31.6% versus 46.2% among the PSCA-negative subgroup.
Conclusions: This randomized, phase II study achieved its primary end point, demonstrating an improved 6-month SR with addition of AGS-1C4D4 to gemcitabine among patients with previously untreated, metastatic pancreatic adenocarcinoma.

AB Background: A multicenter NCI-sponsored phase II study was conducted to analyze the safety and efficacy of the combination of ixabepilone with trastuzumab in patients with metastatic HER2-positive breast cancer.
Patients and methods: Two cohorts were enrolled: cohort 1 had received no prior chemotherapy or trastuzumab for metastatic disease and cohort 2 had received 1-2 prior trastuzumab-containing regimens for metastatic disease. Patients in both cohorts received ixabepilone 40 mg/m(2) as a 3-h infusion and trastuzumab on day 1 of a 21-day cycle. Tumor biomarkers that may predict response to trastuzumab were explored.
Results: Thirty-nine women entered the study with 15 patients in cohort 1 and 24 patients in cohort 2. Across both cohorts, the overall RR was 44%, with a clinical benefit rate (CR + PR + SD for at least 24 weeks) of 56%. Treatment-related toxic effects included neuropathy (grade >= 2, 56%), leukopenia (grade >= 2, 26%), myalgias (grade >= 2, 21%), neutropenia (grade >= 2, 23%), and anemia (grade >= 2, 18%).
Conclusions: This represents the first study of the combination of ixabepilone with trastuzumab for the treatment of metastatic HER2-positive breast cancer. These results suggest that the combination has encouraging activity as first and subsequent line therapy for metastatic breast cancer.

AB Background: Research studies involving human tissue are increasingly common. However, patients' attitudes toward research biopsies are not well characterized, particularly when the biopsies are carried out outside the context of therapeutic trials.
Patients and methods: One hundred sixty patients with metastatic breast cancer (MBC) from two academic (n = 80) and two community (n = 80) hospitals completed a 29-item self-administered survey to evaluate their willingness to consider providing research purposes only biopsies (RPOBs) (as a stand-alone procedure) and additional biopsies (ABs) (additional needle passes at the time of a clinically indicated biopsy).
Results: Eighty-two (51%) of 160 patients would consider having RPOBs, of which 42 (53%) and 40 (50%) patients were from academic and community hospitals, respectively. Patients who had more prior biopsies were less likely to consider RPOBs (RR = 0.6, 95% Cl: 0.4-1.0, P = 0.03). Of 160 patients, 115 (72%) patients would consider having ABs. Of these, 64 (80%) and 51(64%) patients from academic and community hospitals, respectively, would consider ABs (RR = 1.2, 95% Cl: 1.0-1.5, P = 0.03).
Conclusions: Many patients with MBC in both academic and community settings report willingness to consider undergoing biopsies for research. Further research is needed to understand ethical, logistical and provider-based barriers to broader participation in such studies.

AB Background: The epidemiological evidence on possible relationships between coffee consumption and prostate cancer (PCa) risk by subtype of the disease (localized, advanced) and fatal PCa risk is limited.
Materials and methods: A population-based cohort of 44 613 Swedish men aged 45-79 years was followed up from January 1998 through December 2010 for incidence of localized (n = 2368), advanced (n = 918) and fatal (n = 515) PCa. We assessed the associations between coffee consumption and localized, advanced and fatal PCa risk using competing-risk regressions. We examined possible effect modification by body mass index (BMI).
Results: For localized PCa, each one cup increase in daily coffee consumption was associated with a 3% reduced risk [sub-hazard ratio (SHR) = 0.97, 95% confidence interval (CI) = 0.95-0.99]. For advanced and fatal PCa, we found a non-significant inverse association; each one cup increase was associated with a 2% reduced risk of advanced [SHR (95% CI) = 0.98 (0.95-1.02)] and fatal PCa [SHR (95% CI) = 0.98 (0.93-1.03)]. We observed evidence of effect modification by BMI for localized PCa (P-interaction = 0.03); the inverse association was stronger among overweight and obese men (BMI >= 25 kg/m(2)) compared with normal-weight men (BMI < 25 kg/m(2)).
Conclusions: We observed a clear inverse association between coffee consumption and risk of localized PCa, especially among overweight and obese men.

AB Objectives: Traditional open techniques for laryngotracheal reconstruction are either single- or double-stage procedures. Some patients may benefit from the presence of a long, single-tube stent, such as an endotracheal tube, but their predicted need for a 2-stage procedure and a persistent tracheostomy is high. We describe a novel technique for airway reconstruction that combines the methods of both single- and double-stage procedures.
Methods: We present a retrospective review of 4 patients. All patients underwent laryngotracheal reconstruction by a single surgeon. After the operation, the airway was stented with nasotracheal intubation. A small stent, fashioned from an endotracheal tube, was placed in the tracheostoma to keep it patent. The patients subsequently underwent extubation and replacement of the tracheostomy tube.
Results: The study included 1 patient with grade 4 subglottic stenosis, 2 patients with grade 3 subglottic stenosis, and 1 patient with a posterior glottic scar. All were tracheostomy tube dependent. Serial bronchoscopy was used to follow the patients for a minimum of 9 months after the operation. All 4 patients have since met the criteria for decannulation.
Conclusions: This hybrid reconstruction merges the advantages of both the single- and double-stage procedures. It adds versatility to the surgical toolbox for airway reconstruction.

ID RUPTURE-RISK; MECHANICAL-PROPERTIES; WALL STRESS; ASSOCIATION;
PREDICTION; DIAMETER; STRENGTH; BEHAVIOR; AGE
AB Background. Surgical management of ascending thoracic aortic aneurysms (aTAAs) relies on maximum diameter, growth rate, and presence of connective tissue disorders. However, dissection and rupture do occur in patients who do not meet criteria for surgical repair. This study investigated the mechanical properties of aTAAs compared with normal human ascending aortas for eventual development of biomechanical aTAA risk models.
Methods. aTAA specimens (n = 18) were obtained from patients undergoing surgical aneurysm repair, and fresh, healthy ascending aortas (n = 19) as controls were obtained from the transplant donor network. Biaxial stretch testing was performed to obtain tissue mechanical properties. Patient-specific aTAA physiologic stress was calculated based on preoperative computed tomography diameter. aTAA and ascending aorta tissue stiffness at respective physiologic stress were determined.
Results. Physiologic stress of aTAA was significantly greater (241.6 +/- 59.4 kPa) than the 74 kPa for normal controls. Tissue stiffness of aTAAs was significantly greater than that of the ascending aortas at their respective physiologic stresses in the circumferential (3041.4 +/- 1673.7 vs 905.1 +/- 358.9 kPa, respectively; p < 0.001) and longitudinal (3498.2 +/- 2456.8 vs 915.3 +/- 368.9 kPa, respectively; p < 0.001) directions. Tissue stiffness of aTAAs positively correlated with aTAA diameter but did not correlate with patient age. No correlation was found between aTAA physiologic stress level and maximum aTAA diameter.
Conclusions. aTAAs are much stiffer than normal ascending aortas at their respective physiologic stress, which was also significantly greater in ATAAs than ascending aortas. Patient-specific physiologic stress did not correlate with maximum aTAA diameter, and patient-specific aTAA wall stress may be a useful variable to predict adverse aTAA events.

AB A wide variety of phytochemicals, mostly flavonoids or polyphenolics, have been shown to possess anticarcinogenic activities. Among these are the grape seed proanthocyanidins (GSPs), which are the active ingredients of grape seed extract (GSE). Substantial in vitro and preclinical in vivo studies have shown the chemopreventive efficacy of GSPs against various forms of cancers in different tumor models. In this issue of the journal, Derry and colleagues show that administration of GSE in the diet reduces azoxymethane-induced colon carcinogenesis in an A/J mouse model. The results of this innovative and comprehensive study indicate that inhibition of azoxymethane- induced colon cancer by dietary GSE is mediated through the induction of apoptosis that is associated with alterations in microRNA (miRNA) and cytokine expression profiles as well as beta-catenin signaling. Notably, the demonstration that miRNA expression is affected by dietary GSE suggests a novel underlying mechanism for the chemopreventive action of GSE in colon cancer and, potentially, other cancers.

AB Background
Macrophages predominate among the inflammatory cells in rejecting allografts. These innate immune cells, in addition to allospecific T cells, can damage cardiomyocytes directly.
Methods and Results
We explored whether sensitive positron emission tomography-computed tomography (PET-CT) imaging of macrophages-avid nanoparticles detects rejection of heart allografts in mice. In addition, we used the imaging method to follow the immunomodulatory impact of angiotensin-converting enzyme inhibitor therapy on myeloid cells in allografts. Dextran nanoparticles were derivatized with the PET isotope copper-64 and imaged 7 days after transplantation. C57BL/6 recipients of BALB/c allografts displayed robust positron emission tomography signal (standard uptake value allograft, 2.8 +/- 0.3; isograft control, 1.7 +/- 0.2; P<0.05). Autoradiography and scintillation counting confirmed the in vivo findings. We then imaged the effects of angiotensin-converting enzyme inhibitor (5 mg/kg enalapril). Angiotensin-converting enzyme inhibitor significantly decreased nanoparticle signal (P<0.05). Histology and flow cytometry showed a reduced number of myeloid cells in the graft, blood, and lymph nodes and diminished antigen presentation (P<0.05 versus untreated allografts). Angiotensin-converting enzyme inhibitor also significantly prolonged allograft survival (12 versus 7 days; P<0.0001).
Conclusions
Nanoparticle macrophage PET-CT detects heart transplant rejection and predicts organ survival by reporting on myeloid cells.

TI A Prediction Model to Identify Patients at High Risk for 30-Day
Readmission After Percutaneous Coronary Intervention
SO CIRCULATION-CARDIOVASCULAR QUALITY AND OUTCOMES
LA English
DT Article
DE outcomes research; percutaneous coronary intervention; performance
measures
ID HOSPITAL READMISSION; REPEAT REVASCULARIZATION; RATES
AB Background
The Affordable Care Act creates financial incentives for hospitals to minimize readmissions shortly after discharge for several conditions, with percutaneous coronary intervention (PCI) to be a target in 2015. We aimed to develop and validate prediction models to assist clinicians and hospitals in identifying patients at highest risk for 30-day readmission after PCI.
Methods and Results
We identified all readmissions within 30 days of discharge after PCI in nonfederal hospitals in Massachusetts between October 1, 2005, and September 30, 2008. Within a two-thirds random sample (Developmental cohort), we developed 2 parsimonious multivariable models to predict all-cause 30-day readmission, the first incorporating only variables known before cardiac catheterization (pre-PCI model), and the second incorporating variables known at discharge (Discharge model). Models were validated within the remaining one-third sample (Validation cohort), and model discrimination and calibration were assessed. Of 36060 PCI patients surviving to discharge, 3760 (10.4%) patients were readmitted within 30 days. Significant pre-PCI predictors of readmission included age, female sex, Medicare or State insurance, congestive heart failure, and chronic kidney disease. Post-PCI predictors of readmission included lack of -blocker prescription at discharge, post-PCI vascular or bleeding complications, and extended length of stay. Discrimination of the pre-PCI model (C-statistic=0.68) was modestly improved by the addition of post-PCI variables in the Discharge model (C-statistic=0.69; integrated discrimination improvement, 0.009; P<0.001).
Conclusions
These prediction models can be used to identify patients at high risk for readmission after PCI and to target high-risk patients for interventions to prevent readmission.

AB Background
Patients with atrial fibrillation (AF) at the highest stroke risk derive the largest benefit from oral anticoagulation (OAC). Those with the highest stroke risk have been paradoxically less likely to receive OAC. This study assessed the association between stroke and bleeding risk on rates of OAC.
Methods and Results
We analyzed OAC use among 10098 patients with AF from 174 community-based outpatient practices enrolled in 2010-2011 in the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF). OAC was defined as warfarin or dabigatran use at study enrollment. Stroke and bleeding risk were calculated using congestive heart failure, hypertension, age, diabetes mellitus, prior stroke (CHADS(2)), and anticoagulation and risk factors in AF (ATRIA) scores, respectively. The mean subject age was 73 years; 58% were men. Overall, 76% of patients received OAC (71% warfarin and 5% dabigatran). The use of OAC increased among those with higher CHADS(2) scores, from 53% for CHADS(2)=0 to 80% for CHADS(2)2 (P<0.001). OAC use fell slightly with increasing ATRIA bleeding risk score, from 81% for ATRIA=3 to 73% for ATRIA5 (P<0.001). A significant interaction existed between ATRIA and CHADS(2) scores (P=0.021). Among those with low bleeding risk, use of OAC increased significantly with increasing stroke risk. Among those with high bleeding risk, CHADS(2) stroke risk had a smaller impact on use of OAC.
Conclusions
In community-based outpatients with AF, use of OAC was high and driven by not only predominantly stroke but also bleeding risk. Stroke risk significantly affects OAC use among those with low bleeding risk, whereas those with high bleeding risk demonstrate consistently lower use of OAC regardless of stroke risk.

AB Background
To evaluate the previously reported excess of thromboembolic events during the 30 days after the end of study (EOS) visit when participants transitioned from blinded therapy to open-label vitamin K antagonist.
Methods and Results
At the EOS visit, open-label vitamin K antagonist was recommended, and the international normalized ratio (INR) was not to be measured until 3 days later to preserve blinding. We analyzed transition strategies, clinical outcomes, and INR values. Event rates are per 100 patient-years. A total of 9248 (65%) participants were taking study drug at EOS, and, between days 3 and 30, an excess of stroke and systemic embolic events were observed in participants assigned to rivaroxaban (rivaroxaban 22 events, event rate 6.42; warfarin 6 events, event rate 1.73; hazard ratio, 3.72; 95% confidence interval, 1.51-9.16; P=0.0044). No INR values were reported for approximate to 5% of participants transitioned to warfarin. By 30 days after EOS, 83% of the warfarin group and 52% of the rivaroxaban group had 1 therapeutic INR value. Median time to first therapeutic INR was 3 days in the warfarin group and 13 days in the rivaroxaban group.
Conclusions
The excess of events at EOS was likely because of a period of inadequate anticoagulation in rivaroxaban participants switched to vitamin K antagonist therapy. If transition from rivaroxaban to vitamin K antagonist is needed, timely monitoring and careful dosing should be used to ensure consistent and adequate anticoagulation.

AB Background
Little is known about the clinical features, procedural risks, or survival of patients receiving replacement versus new implantable cardioverter-defibrillators (ICDs).
Methods and Results
Entries in the National Cardiovascular Data Registry (NCDR) ICD Registry from 2005 through 2010 were eligible for inclusion (n=463978). Baseline demographic data, clinical information, and procedural variables were compared between patients receiving new (n=359993; 77.6%) and replacement (n=103985; 22.4%) ICDs and entered into a propensity match model to determine adjusted survival rates. Patients receiving replacement ICDs were older (70.7 versus 67.5 years of age) and more likely to have atrial fibrillation (41.8% versus 31.4%; P<0.001) and ventricular tachycardia (60.5% versus 33.9%; P<0.001) compared with patients receiving new ICDs. Median battery life was only 4.6 years (25%-75% interquartile range, 3.7-5.8) for all replaced devices, 5.8 (25%-75% interquartile range, 4.2-7.5) for single-chamber, 5.1 (25%-75% interquartile range, 4.1-6.1) for dual-chamber, and 3.9 (25%-75% interquartile range, 3.2-4.6) years for biventricular devices. Patients receiving replacement ICDs had lower rates of index admission complications (0.9% versus 3.2%; P<0.001) but greater risk for death compared receiving patients receiving new ICDs in unadjusted analysis (hazard ratio, 1.18; 95% confidence interval, 1.16-1.20; P<0.0001) and after propensity-score matching (hazard ratio, 1.28; 95% confidence interval, 1.25-1.30; P<0.0001).
Conclusions
Patients receiving replacement ICDs are older and at greater risk for death compared with those receiving initial ICD implants. The battery life of initial ICDs is shorter than previously reported.

AB Background
Depression and anxiety in patients with cardiac disease are common and independently associated with morbidity and mortality. We aimed to explore the use of a 3-step approach to identify inpatients with cardiac disease with depression, generalized anxiety disorder (GAD), or panic disorder; understand the predictive value of individual screening items in identifying these disorders; and assess the relative prevalence of these disorders in this cohort.
Methods and Results
To identify depression and anxiety disorders in inpatients with cardiac disease as part of a care management trial, an iterative 3-step screening procedure was used. This included an existing 4-item (Coping Screen) tool in nursing data sets, a 5-item screen for positive Coping Screen patients (Patient Health Questionnaire-2 [PHQ-2], GAD-2, and an item about panic attacks), and a diagnostic evaluation using PHQ-9 and the Primary Care Evaluation of Mental Disorders anxiety disorder modules. Overall, 6210 inpatients received the Coping Screen, 581 completed portions of all 3 evaluation steps, and 210 received a diagnosis (143 depression, 129 GAD, 30 panic disorder). Controlling for age, sex, and the other screening items, PHQ-2 items independently predicted depression (little interest/pleasure: odds ratio [OR]=6.65, P<0.001; depression: OR=5.24, P=0.001), GAD-2 items predicted GAD (anxious: OR=4.09, P=0.003; unable to control worrying: OR=10.46, P<0.001), and the panic item predicted panic disorder (OR=49.61, P<0.001).
Conclusions
GAD was nearly as prevalent as depression in this cohort, and GAD-2 was an effective screening tool; however, panic disorder was rare. These results support the use of 2-step screening for depression and GAD beginning with a 4-item scale (GAD-2 plus PHQ-2).

AB Scleroderma refers to a heterogeneous group of autoimmune fibrosing disorders. The nomenclature of scleroderma has changed dramatically in recent years, with morphea (localized scleroderma), limited cutaneous systemic sclerosis, diffuse cutaneous systemic sclerosis, and systemic sclerosis sine scleroderma encompassing the currently accepted disease subtypes. Major advances have been made in the molecular studies of morphea and systemic sclerosis; however, their etiologies and pathogenesis remain incompletely understood. Although morphea and systemic sclerosis demonstrate activation of similar inflammatory and fibrotic pathways, important differences in signaling pathways and gene signatures indicate they are likely biologically distinct processes. Morphea can cause significant morbidity but does not affect mortality, whereas systemic sclerosis has the highest disease-specific mortality of all autoimmune connective tissue diseases. Treatment recommendations for morphea and systemic sclerosis are based on limited data and largely expert opinions. Current collaborative efforts in morphea and systemic sclerosis research will hopefully lead to better understanding of the etiology and pathogenesis of these rare and varied diseases and improved treatment options.

DE Solitary fibrous tumour; Pleura; Recurrence
ID SURGICAL-TREATMENT; EXPRESSION
AB OBJECTIVES: Surveillance after resection of solitary fibrous tumours of the pleura (SFTP) remains undefined. This study reviews our experience with surgical treatment of SFTP to determine the specific risk factors to predict recurrence.
METHODS: A retrospective review of 59 patients surgically treated for SFTP during the years 1977-2010 was conducted. Clinico-pathological factors for recurrence were analysed by Kaplan-Meier and Cox proportional hazard methods.
RESULTS: The mean age was 57 +/- 14 years. There were 32 (54%) men. Among 32 (54%) symptomatic patients, chest pain (22%), cough (19%) and dyspnoea (17%) were most frequent. The mean tumour size was 7.3 +/- 6.7 cm, and 14 patients had SFTPs larger than 10 cm. An SFTP was pedunculated in 38 (67%) cases and had a visceral origin in 40 (68%). Paraneoplastic syndromes were observed in 3 (5%) patients. On histopathologic analysis, 4 (7%) presented >= 4 mitosis/10 high-power fields (HPFs), 8 (15%) atypia, 14 (24%) hypercellularity and 6 (10%) necrosis. After a mean follow-up of 8.8 +/- 7.0 years, we observed 8 (14%) recurrences; median time to recurrence was 6 years (range 2-16 years). Two (3%) patients received adjuvant therapy. We constructed a predictive score for recurrence by assigning one point to each of the six variables: parietal (vs visceral) pleural origin, sessile (vs pedunculated) morphology, size >10 cm (vs <10 cm), the presence of hypercellularity, necrosis and mitotic activity >= 4/HPF (vs <4). A score of >= 3 best predicted recurrence (sensitivity: 100%, specificity: 92%, area under receiver operating characteristic curve = 0.966, P < 0.0001). With a score of = 3, recurrence-free survival was 80%, 69, 23 and 23% at 3, 5, 10 and 15 years, whereas a score of < 3 was 100% up to 15 years. Our scoring system was superior in predicting malignant behaviour and recurrence compared with England's criteria or de Perrot staging.
CONCLUSIONS: The proposed scoring system is simple, easily obtained from existing pathological description and reliably predicts recurrence in this patient population harbouring SFTP. The SFTP score may stratify patient risk and guide postoperative surveillance. We recommend validation in additional clinical series.

AB Cigarette smoking deleteriously affects erectile function, and conversely, quitting smoking improves erectile hemodynamics. Underlying mechanisms by which smoking (or reduction of smoking frequency) may affect erectile physiology are not well understood. This study examined the mediating role of heart rate variability (HRV; a marker of sympathovagal balance) among a sample of male chronic smokers from the United States. Sixty-two healthy men (M-age = 38.27 years; s.d. = 10.62) were assessed at baseline (while smoking regularly), at mid-treatment (while using a nicotine patch) and at follow-up, 4 weeks after patch discontinuation. Cigarette use, frequency-domain parameters of HRV (low frequency (LF), high frequency (HF), LF/HF ratio) and physiological sexual arousal responses (via penile plethysmography) were assessed at each visit. Results were consistent with mediation, in that greater reductions in cigarette use from baseline to follow-up were associated with longitudinal increases in LF, which in turn showed positive relationships with across-time changes in erectile tumescence. Neither HF nor LF/HF ratio mediated the relationship between smoking and erection. In conclusion, HRV mediated the inverse relationship between reductions in smoking and enhancements in erectile tumescence. Results underscore the possibility that cigarette use may deleteriously affect erectile function peripherally, in part, by disrupting cardiac autonomic function.

AB This article describes the influence of abusive and nonabusive relationship dynamics on the number of sex partners among urban adolescent girls. Focus groups were conducted with 64 sexually active adolescent girls ages 14 to 17 years. General coding and content analyses identified patterns, themes, and salient beliefs. More than one third (37.5%) reported having experienced physical, intimate partner violence; 32.8% had two or more recent sex partners, and 37.5% had ever had a sexually transmitted infection (STI) or HIV. Although some girls in abusive relationships feared retribution if they had more than one partner, others sought additional partners for solace or as an act of resistance. Adolescent HIV/STI prevention programs need to address the influence of gender norms such as the sexual double standard, as well as partner pressure and partner abuse on adolescent decision-making about safer sex, and also promote healthy relationships as integral to advancing HIV/STI risk reduction.

AB Diabetes has become a global pandemic and Chinese Americans are at least 60% more likely to develop type 2 diabetes than White Americans, despite having lower body weight, due to a combination of genetic and environmental factors. Because of the increased risk, it is vitally important to address the issues of treatment adherence and diabetes self-management in the Chinese American population. Many factors affect an individual's ability to manage diabetes, including cultural beliefs, immigration experience, language abilities/health literacy, educational background, employment, and accessibility of healthcare services. In treating Chinese American patients, these factors must be considered to determine appropriate treatment. Eastern cultural and individual beliefs differ greatly from Western beliefs and, therefore, may affect the presentation of the patients. If left unacknowledged, these differences might be misinterpreted by healthcare providers as merely treatment non-adherence or unwillingness to change. Suggestions for providing culturally competent healthcare are discussed. (C) 2013 Elsevier Inc. All rights reserved.

TI Safety of full-dose intravenous recombinant tissue plasminogen activator
followed by multimodal endovascular therapy for acute ischemic stroke
SO JOURNAL OF NEUROINTERVENTIONAL SURGERY
LA English
DT Article
ID INTRAARTERIAL THROMBOLYSIS; INTERVENTIONAL MANAGEMENT; RECANALIZATION;
TRIAL
AB Background and purpose The optimal management of stroke patients who fail treatment with intravenous recombinant tissue plasminogen activator (rt-PA) remains unknown. A study was undertaken to establish whether treatment with a standard intravenous t-PA dose (0.9 mg/kg) followed by multimodal endovascular therapy would have a similar safety profile to reduced dose (0.6 mg/kg) bridging therapy.
Methods A retrospective analysis was performed of a prospectively collected database. All patients treated with full-dose t-PA and endovascular therapy were included. The primary safety endpoints included ECASS-III symptomatic intracranial hemorrhage (sICH) and ECASS parenchymal hematomas (PH). Secondary safety endpoints included severe systemic bleeding and 90-day mortality. Clinical efficacy endpoints included rates of recanalization (TICI 2-3), ambulation at hospital discharge and 90-day independent outcomes (mRS 0-2).
Results 106 consecutive patients (mean age 69 +/- 17 years; mean baseline NIH Stroke Scale 17.8 +/- 4.8; 55% women; occlusion sites: MCA-M1 60.4%; MCA-M2 6.6%; ICA-T 19.8%; tandem cervical ICA+MCA-M1 7.5%; basilar artery 5.7%) were identified over a 10-year period. The sICH rate was 8.5% and the PH-1, PH-2 and subarachnoid hemorrhage rates were 2.8%, 8.5% and 2.8%, respectively. There were two (1.9%) severe groin hematomas. The recanalization rate was 66%. At hospital discharge, 41.4% of the patients were ambulatory. The rate of independent functional outcomes at 90 days was 24%; however, this sample is biased since nearly all deaths were captured but detailed 90-day functional outcomes were missing in 27 patients. The 90-day death rate was 32.4%.
Conclusion Combined treatment with full-dose intravenous rt-PA followed by multimodal endovascular therapy seems to be associated with similar rates of sICH to that of bridging therapy with reduced rt-PA dosage.

TI ONYX versus n-BCA for embolization of cranial dural arteriovenous
fistulas
SO JOURNAL OF NEUROINTERVENTIONAL SURGERY
LA English
DT Article
ID VENOUS DRAINAGE; TRANSARTERIAL EMBOLIZATION; MALFORMATIONS;
CLASSIFICATION; MANAGEMENT; SHUNTS; SWINE
AB Purpose To evaluate the efficacy of n-butyl-2-cyanoacrylate (Trufill n-BCA) versus ethylene vinyl alcohol copolymer (ONYX) for the embolization of cranial dural arteriovenous fistulas (DAVF).
Methods Fifty-three consecutive patients with cranial dural AVF were treated with liquid embolic agents from November, 2003 to November, 2008. These 53 patients had 56 lesions treated with arterial embolization. Patients embolized to completion underwent follow-up angiography at 3 months to assess for durable occlusion.
Results Twenty-one lesions were treated with n-BCA. Seven patients treated with n-BCA had initial angiographic occlusion of their DAVF, which were durable at 3 months. Six patients had adjunctive treatment with coils and/or polyvinyl alcohol particles, but none of these were occluded by endovascular treatment alone. Eleven patients underwent post-embolization surgery for closure of their DAVF. There was one death related to intractable status epilepticus at presentation. One patient developed a major stroke from venous sinus thrombosis after embolization. Thirty-five lesions were treated with ONYX in 34 patients. Twenty-nine patients treated with ONYX had initial angiographic occlusion of their DAVF by embolization alone. One patient had recurrence at 3 months and was re-treated out of 27 total follow-ups. Four patients underwent post-embolization surgical obliteration of their lesions. No deaths or major strokes occurred in this cohort.
Conclusion Initial angiographic occlusion (p=0.0004) and durable angiographic occlusion (p=0.0018) rates for embolization of cranial DAVF show a statistically significant higher efficacy with ONYX compared with n-BCA. Patients embolized with ONYX underwent surgery less frequently compared with those treated with n-BCA (p=0.0015).

TI Sustainable growth rate 2013: time for definitive intervention
SO JOURNAL OF NEUROINTERVENTIONAL SURGERY
LA English
DT Review
ID PHYSICIAN-PAYMENT OUTLOOK; PRIMER
AB Federal healthcare spending has been a subject of intense concern as the US Congress continues to search for ways to reduce the budget deficit. The Congressional Budget Office (CBO) estimated that, even though it is growing more slowly than previously projected, federal spending on Medicare, Medicaid and the State Children's Health Insurance Program (SCHIP) will reach nearly $900 billion in 2013. In 2011 the Medicare program paid $68 billion for physicians and other health professional services, 12% of total Medicare spending. Since 2002 the sustainable growth rate (SGR) correction has called for reductions to physician reimbursements; however, Congress has typically staved off these reductions, although the situation remains precarious for physicians who accept Medicare. The fiscal cliff agreement that came into focus at the end of 2012 averted a 26.5% reduction to physician reimbursements related to the SOB correction. Nonetheless, the threat of these devastating cuts continues to loom. The Administration, Congress and others have devised many options to fix this unsustainable situation. This review explores the historical development of the SGR, touches on elements of the formula itself and outlines current proposals for fixing the SOB problem. A recent CBO estimate reduces the potential cost of a 10-year fix of SGR system to $138 billion. This has provided new hope for resolution of this long-standing issue.

AB We compared mental health outpatient, primary care, and emergency care service utilization among veterans screening TBI positive (S-TBI+) versus those screening TBI negative (S-TBI-) and describe associations between TBI-related symptoms and health service utilization. Our study population consisted of 1746 Iraq and Afghanistan veterans in VA care screened for TBI between April 1, 2007 and June 1, 2010. Rates of mental health outpatient, primary care, and emergency services utilization were greater for S-TBI+ veterans, compared with S-TBI- veterans, even after adjusting for mental health screen results. Irritability on the initial TBI screen was associated with increased mental health outpatient utilization rates [incidence rate ratio (IRR), 1.64; 95% confidence interval (CI), 1.18-2.3; p < 0.01]. Reports of dizziness (IRR, 1.24; 95% CI, 1.02-1.51; p < 0.05) and headaches (IRR, 1.41; 95% CI, 1.16-1.7; p < 0.001) were associated with increased primary care utilization rates. Higher utilization rates among veterans who screened positive for TBI were not better explained by screening positive for comorbid mental health problems. Knowing that certain symptoms are more strongly associated with increased utilization in certain health service domains will help to better plan for the care of returning veterans who screen positive for TBI.

AB Context. People with chronic obstructive pulmonary disease experience dyspnea with activities despite optimal medical management.
Objectives. The purpose of this study was to test the efficacy of two 12-month dyspnea self-management programs (DSMPs), Internet-based (eDSMP) and face-to-face (fDSMP), compared with a general health education (GHE) control on the primary outcome of dyspnea with activities.
Methods. Participants with chronic obstructive pulmonary disease were randomized to eDSMP (n = 43), fDSMP (n = 41), or GHE (n = 41). The content of the DSMPs were similar and focused on education, skills training, and coaching on dyspnea self-management strategies, including exercise, and only differed in the delivery mode. Dyspnea with activities was measured with the Chronic Respiratory Questionnaire at three, six, and 12 months. Secondary outcomes included exercise behavior and performance, health-related quality of life, self-efficacy for dyspnea management, and perception of support for exercise. The study was registered at Clinicaltrials.gov (NCT00461162).
Results. There were no differences in dyspnea with activities across groups over 12 months (P = 0.48). With the exception of arm endurance (P = 0.04), exercise behavior, performance, and health-related quality of life did not differ across groups (P > 0.05). Self-efficacy for managing dyspnea improved for the DSMPs compared with GHE (P = 0.06). DSMP participants perceived high levels of support for initiating and maintaining an exercise program.
Conclusion. The DSMPs did not significantly reduce dyspnea with activities compared with attention control. However, the high participant satisfaction with the DSMPs combined with positive changes in other outcomes, including self-efficacy for managing dyspnea and exercise behavior, highlight the need for additional testing of individually tailored technology-enabled interventions to optimize patient engagement and improve clinically relevant outcomes.

AB Diet plays a critical role in the pathogenesis of major Chronic diseases common in populations of US veterans. The role of nutrition-focused wellness coaching in improving dietary behavior and/or reducing weight in overweight and obese US veterans is not known. At the San Francisco Veterans Affairs Medical Center, US veterans aged 25 to 80 years were randomized to receive nutrition coaching on eating behaviors at baseline only (control group, n=22) or an additional eight times over the course of 6 months (intervention group, n=28) in 2010-2011. Multiple coaching contacts decreased intake of energy, fat, and carbohydrate by 31% (P <= 0.001) as evaluated by the 2005 Block food frequency questionnaire, which is composed of 111 food items. A weight loss of 5% from baseline (92.8 to 88.2 kg; P<0.01) was observed in the intervention group with mean body mass index decreasing from 30.4 to 28.9 (P<0.05). The control group showed a decrease in fat intake by 20% (P=0.01), but no statistically significant changes in intake of other nutrients or body weight (88.7 to 87.4 kg). Those in the intervention group reported diets at follow-up that were lower in cholesterol, saturated fat, sodium, sugar (P <= 0.01), calcium (P<0.05), and vitamin D (P<0.01), although when adjusted for energy (le, nutrient density) calcium intake increased and vitamin D remained unchanged. Veterans' readiness to change eating behavior for weight loss improved with nutrition coaching. This study demonstrates that intermittent nutrition coaching can be an effective strategy to promote reductions in energy intake, body weight, and body mass index in overweight US veterans. Further research is needed to determine whether nutrition coaching improves other clinical outcomes and sustains weight loss.

AB Purpose: The aims of this study were to review patients' complaints about their care in radiology and to determine key areas for improvement.
Methods: An institutional review board approved, HIPAA-compliant study was conducted to retrospectively evaluate all radiology-related patient complaints received by the authors' institution's Office of Patient Advocacy from April 1999 to December 2010. The internal review classified the complaints into those that concerned medical complications, radiology staff members, failure to provide patient-centered care, and those that related to quality on the basis of radiologic benchmarks of safety, systems, and professionalism. The rate of successful complaint resolution was also tallied. The incidence of complaints per modality was calculated as a fraction of the total number of radiologic examinations performed.
Results: A total of 153 radiology-related complaints were identified. The majority of complaints (60.1% [92 of 153]) described a failure to provide patient-centered care. Of the remaining complaints, 26.2% (40 of 153) reported physical discomfort, 10.5% (16 of 153) reported a combination of both physical discomfort and lack of patient-centered care, and 3.2% (5 of 153) were not related to either category. Of the complaints regarding quality, 44.5% (68 of 153) were associated with operational systems, 24.2% (37 of 153) with safety, 17% (26 of 153) with professionalism, and 14.3% (22 of 153) with multifactorial events. Delays accounted for 20.2% of complaints (31 of 153), and 49.6% of complaints (76 of 153) concerned radiology staff members. Complaint resolution was achieved in 83.6% of cases (128 of 153). The overall incidence of complaints per radiologic procedure was 0.238 per 10,000. The incidence of complaints associated with interventional procedures (3.26 per 10,000) was significantly (P < .05) higher than the incidence of those associated with noninterventional examinations (0.138 per 10,000).
Conclusions: Failure to provide patient-centered care was the most common complaint; most of these complaints could be attributed to systems issues. There was a higher incidence of complaints related to interventional procedures than diagnostic examinations. Delays and providers' interactions with patients were identified as key areas for improvement.

AB Background: Lesbian and bisexual (i.e., sexual minority) identity is more common among women veterans than among male veterans. Unique health issues have been identified among women veterans and among sexual minority women, but little is known about women who are both sexual minorities and veterans. This study aimed to compare demographic and health information from sexual minority women veterans with sexual minority women non-veterans and heterosexual women veterans.
Methods: Behavioral Risk Factor Surveillance Survey data were pooled from ten U. S. states that elected to ask sexual identity during 2010. The analytic sample was comprised of women who identified both their sexual identity and veteran status (n = 1,908). Mental health indicators were frequent mental distress, sleep problems, low social/emotional support, and low satisfaction with life. Health risk indicators included current smoking, overweight, and obesity. Physical health status was defined by three components: disability requiring assistive equipment, > 14 days of poor physical health in the past 30 days, and activity limitations.
Results: Compared with heterosexual women veterans, sexual minority women veterans had higher odds of mental distress (odds ratio [OR] = 3.03, 95% confidence interval [CI]: 1.61-5.70) and smoking (OR = 2.31, 95% CI: 1.19-4.48). After adjusting for demographic correlates, sexual minority women veterans had three times the odds of poor physical health (OR = 3.01, 95% CI: 1.51-5.99) than their sexual minority non-veteran peers.
Conclusions: Results suggest sexual minority women veterans may experience unique health disparities relevant to provision of care in both Veterans Affairs (VA) and non-VA healthcare systems. Future research requires availability of data that include sexual minority status.

AB Introduction. Accumulating evidence suggests that patients with type 2 diabetes mellitus (T2DM) and hyperinsulinemia are at increased risk for developing malignancies. It remains to be fully elucidated whether use of metformin, an insulin sensitizer, and/or sulfonylureas, insulin secretagogues, affect cancer incidence in subjects with T2DM.
Material & Methods. We performed a meta-analysis using PubMed, of randomized control trials (RCTs), cohorts, and case-control studies published through July 2012 that assess effects of metformin and/or sulfonylurea sulfonylureas on cancer risk at any site, in subjects with T2DM. Fixed and random effects meta-analysis models were used, and the effect size was summarized as relative risk (RR) for RCTs/cohorts and as odds ratio (OR) for the case-control studies.
Results. Analysis of 24 metformin studies in subjects with T2DM showed that metformin use is associated with reduced risk for the development of cancer, in both cohort (RR=0.70 [95% CI=0.67-0.731) and case-control studies (OR=0.90 [95% CI=0.84-0.98]), but this finding was not supported by RCTs (RR=1.01[95% CI=0.81-1.26]). Data from 18 sulfonylurea studies in subjects with T2DM showed that sulfonylurea use is associated with an increase in all-cancer risk, in cohort studies (RR=1.55 [95% CI=1.48-1.63]), though data from RCTs (RR=1.17 [95% CI=0.95-1.45]) and case-control studies (OR=1.02 [95% CI=0.93-1.13]) failed to demonstrate a statistically significant effect.
Conclusions. This analysis using pooled primary data demonstrates that metformin use reduces, while sulfonylurea use may be associated with an increased cancer risk in subjects with T2DM. These findings need to be confirmed in large-scale RCTs before they are translated into clinical practice. Published by Elsevier Inc.

AB Single-stranded oligonucleotides are important as research tools, as diagnostic probes, in gene therapy and in DNA nanotechnology. Oligonucleotides are typically produced via solid-phase synthesis, using polymer chemistries that are limited relative to what biological systems produce. The number of errors in synthetic DNA increases with oligonucleotide length, and the resulting diversity of sequences can be a problem. Here we present the 'monoclonal stoichiometric' (MOSIC) method for enzyme-mediated production of DNA oligonucleotides. We amplified oligonucleotides from clonal templates derived from single bacterial colonies and then digested cutter hairpins in the products, which released pools of oligonucleotides with precisely controlled relative stoichiometric ratios. We prepared 14-378-nucleotide MOSIC oligonucleotides either by in vitro rolling-circle amplification or by amplification of phagemid DNA in Escherichia coli. Analyses of the formation of a DNA crystal and folding of DNA nanostructures confirmed the scalability, purity and stoichiometry of the produced oligonucleotides.

AB Neurotrophins and their receptors modulate multiple signalling pathways to regulate neuronal survival and to maintain axonal and dendritic networks and synaptic plasticity. Neurotrophins have potential for the treatment of neurological diseases. However, their therapeutic application has been limited owing to their poor plasma stability, restricted nervous system penetration and, importantly, the pleiotropic actions that derive from their concomitant binding to multiple receptors. One strategy to overcome these limitations is to target individual neurotrophin receptors-such as tropomyosin receptor kinase A (TRKA), TRKB, TRKC, the p75 neurotrophin receptor or sortilin-with small-molecule ligands. Such small molecules might also modulate various aspects of these signalling pathways in ways that are distinct from the programmes triggered by native neurotrophins. By departing from conventional neurotrophin signalling, these ligands might provide novel therapeutic options for a broad range of neurological indications.

AB Background. Anemia is a common complication of chronic kidney disease (CKD) that negatively impacts the quality of life and is associated with numerous adverse outcomes. Excess levels of the iron regulatory hormone hepcidin are thought to contribute to anemia in CKD patients by decreasing iron availability from the diet and from body stores. Adenine treatment in rats has been proposed as an animal model of anemia of CKD with high hepcidin levels that mirrors the condition in human patients.
Methods. We developed a modified adenine-induced kidney disease model with a higher survival rate than previously reported models, while maintaining persistent kidney disease and anemia. We then tested whether the small molecule bone morphogenetic protein (BMP) inhibitor LDN-193189, which was previously shown to lower hepcidin levels in rodents, mobilized iron into the plasma and improved iron-restricted erythropoiesis in this model.
Results. Adenine-treated rats exhibited increased hepatic hepcidin mRNA, decreased serum iron, increased spleen iron content, low hemoglobin (Hb) and inappropriately low erythropoietin (EPO) levels relative to the degree of anemia. LDN-193189 administration to adenine-treated rats lowered hepatic hepcidin mRNA, mobilized stored iron into plasma and increased Hb content of reticulocytes.
Conclusions. Our data suggest that hepcidin lowering agents may provide a new therapeutic strategy to improve iron availability for erythropoiesis in CKD.

AB Purpose: Immunoglobin G4 (IgG4)-related disease is a systemic condition characterized by lymphoplasmacytic infiltrates that can involve the orbit. The purpose of this study was to identify the various patterns of orbital IgG4-related disease on imaging.
Methods: Retrospective review of radiologic examinations including CT, MRI, and positron emission tomography was performed in patients with proven cases of IgG4-related disease.
Results: A total of 9 patients with orbital IgG4-related disease were identified, including 9 with CT, 4 with MRI, and 4 with 18-fluorodeoxyglucose positron emission tomography. Patterns of involvement included lacrimal gland enlargement, lacrimal sac involvement, extraocular muscle thickening, preseptal involvement, orbital fat involvement, and cranial nerve involvement, many of which occurred simultaneously. Associated demineralization of the orbital wall was evident on CT in 2 cases. On T2-weighted MRI, the lesions appeared as hypointense in 2 cases, heterogeneously hypointense to isointense in 1 case, and hyperintense in 1 case. Diffuse enhancement was present in all 3 cases in which postcontrast T1-weighted sequences were available. The lesions were hypermetabolic on positron emission tomography in 3 of 4 cases. There was definite extraorbital involvement by IgG4-related disease in 3 of the 9 patients and suspected involvement in another 3 of the 9 patients.
Conclusions: IgG4-related disease displays a wide variety of imaging manifestations in the orbit. Extraorbital disease is often present and can help suggest the diagnosis.

AB Purpose: To investigate the necessity and usefulness of prophylactic postoperative antibiotics in patients undergoing enucleation or ocular evisceration.
Methods: A retrospective, multicenter, comparative case series was designed. After obtaining Institutional Review Board authorization, a medical records' review was conducted. Demographics, indication for surgery, surgical technique, postoperative antibiotic dosing, and postoperative course were evaluated. Records were grouped according to antibiotic protocols, and presence or absence of postoperative wound infection (orbital cellulitis) was recorded. Rates of postoperative infection were analyzed statistically.
Results: Between 1996 and 2011, 666 evisceration or enucleation surgeries were conducted at 4 institutions. Six hundred forty-eight records were available for analysis, of which 4 were excluded due to insufficient follow-up data. All the remaining 644 patients received a single, perioperative, intravenous dose of antibiotics. Five hundred seventy-eight patients (90%) received an orbital implant, while 66 (10%) did not. Three hundred eighty-one patients (59%) received postoperative antibiotics, and 263 patients (41%) did not. Two cases were identified with signs suggestive of infection, but no culture-positive infections were found, and no patient was admitted to the hospital for management. Of the 2 suspicious cases, 1 was found in the group that received postoperative antibiotics (group 1) and 1 in the group that did not receive postoperative antibiotics (group 2). No statistically significant difference in postoperative infection rate was noted between the 2 groups (p = 0.52). While patients with infectious indications for surgery were more likely to receive postoperative antibiotics (p < 0.001), there was no statistically significant difference in rates of infection among patients with infectious indications for surgery based on receiving or not receiving postoperative antibiotics (p = 0.79), and no patients with infectious indications for surgery not receiving postoperative antibiotics developed a postoperative infection.
Conclusions: This study demonstrates the clinical safety of withholding postoperative prophylactic antibiotics in orbital surgery even when implanting alloplastic material in a sterile field. Furthermore, Centers for Disease Control and Prevention guidelines mandate cessation of postoperative antibiotics within 24 hours of surgery. Surgeons are cautioned not to generalize these results to nonsterile surgery such as sinonasal or nasolacrimal surgery.

AB Nevus comedonicus is a rare developmental abnormality of the infundibulum of the hair follicle. It is usually unilateral and commonly presents at birth or during childhood. A rare case of late-onset, bilateral nevus comedonicus of the eyelids is reported. A 79-year-old man presented with asymptomatic but disfiguring eyelid lesions noted several months earlier. On physical examination, multiple papules resembling comedones were present bilaterally in the eyelids, canthi, temple regions, and bridge of the nose. Microscopically, there were deep invaginations of the follicular canals forming focal tunnels or pseudosinus tracts with poral openings to the surface. These variably cystic structures were lined by keratinizing and nonkeratinizing squamous epithelium, contained concentric lamellae of keratin in their lumens, and some were acutely or chronically inflamed. The diagnosis of a nevus comedonicus was made. The clinical and histopathologic characteristics, pathogenesis, differential diagnosis, and management of nevus comedonicus are briefly discussed.

TI Gaze-Evoked Amaurosis From Orbital Breast Carcinoma Metastasis
SO OPHTHALMIC PLASTIC AND RECONSTRUCTIVE SURGERY
LA English
DT Article
ID FUGAX
AB Gaze-evoked amaurosis (GEA) is a transient monocular vision loss provoked by eccentric gaze. Gaze-evoked amaurosis has been associated with a variety of orbital lesions, most commonly optic nerve sheath meningiomas and cavernous hemangiomas. The authors describe the first report in the literature of GEA as the presenting symptom of an orbital metastasis. The patient was a 47-year-old woman with a history of breast cancer with no known history of metastasis or active disease who presented with several weeks of vision loss in the OD upon rightward gaze. She was found to have enophthalmos and optic disc edema of the OD. Imaging revealed an intraorbital lesion, and a biopsy was consistent with a scirrhous metastasis of her breast carcinoma. This case highlights the importance of considering orbital metastases among the differential for gaze-evoked amaurosis.

ID CONJUNCTIVAL FIBROMA
AB A 40-year-old woman with left periorbital swelling for 1 month presented without diplopia or change in vision. Imaging studies revealed a 1-cm mass at the frontozygomatic junction at the orbital rim with slight bony erosion and spiculation. The lesion was applied to the periosteum and was excised along with a portion of the bony orbital rim. Histopathology revealed elongated and stellate fibroblasts within a dense collagenous matrix. Vimentin and Masson trichrome staining was consistent with a collagenous fibroma, a rare tumor that has, only once before, been reported in the orbit in the lacrimal fossa region. The current collagenous fibroma arose from the periosteum to grow exophytically, causing minimal bone changes. A literature review shows that this condition predominantly affects middle-aged and older adults rather than children.

AB The predominant cause of death in diabetes mellitus (DM) is coronary artery disease (CAD). Little is known about prevalence of silent ischemia in developing nations. We compared prevalence of silent ischemia in DM to a control group by exercise myocardial perfusion imaging (MPI) and electrocardiogram (ECG) in developing nations. The prospective multinational Ischemia Assessment with Exercise imaging in Asymptomatic Diabetes study recruited. participants at 12 sites in Asia, Africa, and Latin America. DM participants were age- and gender-matched 2:1 to non-DM individuals with >= 1 CAD risk factor. Subjects, underwent exercise tests that were interpreted in core labs in blinded fashion. The study included 392 DM and 205 control participants. Among participants with diagnostic ECGs, a similar proportion of DM and controls had ischemic ECG (15% vs 12%, p = 0.5). A significantly higher proportion of DM group had MPI abnormalities compared with controls (26% vs 14%, p <0.001). In participants with ischemia on MPI, only 17% had ischemic ECG, whereas in those without ischemia on MPI, 10% had ischemic ECG. In a multivariable model, DM was independently associated with abnormal MPI (odds ratio 2.1, 95% confidence interval 1.3-3.5, p = 0.004). Women were less likely to have ischemia by MPI than men (10% vs 30%, p <0.001) and concordance between ECG and MPI was much worse in women. In conclusion, in this large prospective study, asymptomatic DM participants had (1) more ischemia by exercise MPI than ECG, (2) more ischemia by MPI but not ECG than control group, and (3) ischemia by MPI was less in women than men.

AB Myocardial extracellular matrix expansion and reduced coronary flow reserve (CFR) occur in patients with type 2 diabetes mellitus without heart failure or coronary artery disease. Because aldosterone is implicated in the pathophysiology of cardiac fibrosis and vascular injury, the aim of this study was to test the hypothesis that aldosterone is associated with extracellular matrix expansion and reduced CFR in type 2 diabetes mellitus. Patients with type 2 diabetes mellitus without evidence of coronary artery disease were recruited. Blood pressure, lipid management, and glycemic control were optimized over 3 months. Cardiac magnetic resonance imaging with T1 mapping was used to measure myocardial extracellular volume (ECV). Cardiac positron emission tomography was used to assess CFR. On a liberal, 250 mEq/day sodium diet, 24-hour urinary aldosterone and change in serum aldosterone with angiotensin II stimulation were measured. Fifty-three participants with type 2 diabetes (68% men, mean age 53 +/- 7 years, mean body mass index 32.2 +/- 4.3 kg/m(2), mean glycosylated hemoglobin 6.8 +/- 0.7%, mean systolic blood pressure 126 +/- 14 mm Hg) without infarction or ischemia by cardiac magnetic resonance and positron emission tomography were studied. Subjects had impaired CFR (2.51 +/- 0.83) and elevated ECV (0.36 +/- 0.05), despite normal echocardiographic diastolic function and normal left ventricular function. Myocardial ECV, but not CFR, was positively associated with 24-hour urinary aldosterone excretion (r = 0.37, p = 0.01) and angiotensin II stimulated aldosterone increase (r = 0.35, p = 0.02). In a best-overall multivariate model (including age, gender, body mass index, glycosylated hemoglobin, and blood pressure), 24-hour urinary aldosterone was the strongest predictor of myocardial ECV (p = 0.004). In conclusion, in patients with type 2 diabetes mellitus without coronary artery disease, aldosterone is associated with myocardial extracellular matrix expansion. These results implicate aldosterone in early myocardial remodeling in type 2 diabetes mellitus. (C) 2013 Elsevier Inc. All rights reserved.

AB Background: APOE e4 genotype is known to be a risk factor for Alzheimer's disease and atherosclerosis. Recently, published evidence has shown that APOE e4 genotype may also be associated with the cessation of cigarette smoking. Objectives: The aim of this retrospective analysis was to explore whether any past smoking outcomes differed based on APOE e4 genotype in a large national dataset. Methods: Data were extracted from the National Alzheimer's Coordinating Center's longitudinal Uniform Data Set study. We limited this retrospective baseline analysis to the normal cognition (n = 2995) and mild cognitive impairment (n = 1627) groups that had APOE genotype and smoking data. Because this was an exploratory retrospective analysis, we conducted descriptive analyses on all variables based on APOE e4 genotype. We controlled for demographic, clinical, medication and neurocognitive data in the analyses. Results: In both the normal cognition group and the mild cognitive impairment group, e4 carriers and e4 non-carriers did not significantly differ on total years smoked, age when last smoked and the average # of packs/day smoked during the years they smoked. In both groups, e4 carriers and e4 non-carriers differed on various neurocognitive measures. Conclusion: These data do not support the recently published evidence of the association between APOE e4 genotype and smoking outcomes. Scientific Significance: Larger prospective clinical trials are needed to further explore the relationship between APOE genotype and smoking outcomes.

TI The frequency and cost of redundant laboratory testing for transferred
ED patients
SO AMERICAN JOURNAL OF EMERGENCY MEDICINE
LA English
DT Article
AB Introduction: Health care costs continue to rise; reducing unnecessary laboratory testing may reduce costs. The goal of this study was to calculate the frequency and estimated costs of repeat normal laboratory testing of patients transferred to a tertiary care emergency department (ED).
Methods: This was a retrospective cohort study of patients transferred to a tertiary care, level -one trauma ED with an annual census of 90,000 patients. We defined "repeat normal testing" as laboratory tests repeated within 8 hours that were normal at both the sending hospital and the receiving tertiary care hospital. We estimated the charges associated with repeat normal laboratory testing for 11 common ED tests: basic metabolic panel, calcium, magnesium, phosphorus, lipase, thyroids stimulating hormone, prothrombin time, partial thromboplastin time, complete blood count, liver function test, and urine analysis.
Results: Two hundred thirty-two patients were transferred to the receiving tertiary care hospital from within the hospital's network from May 1, 2011, to October 31, 2011. On average, each transferred patient had one repeat normal laboratory test (245/232 = 1.06). For all laboratory tests, repeat normal testing occurred at least 40% of the time. Extrapolating the data, the total yearly estimated charges of all repeat normal testing was $580,526.
Conclusion: This study provides the first analysis of the frequency of repeated laboratory testing for all transferred ED patients and indicates that repeat normal testing represents a significant cost. Future research needs to determine if such repeat testing is indeed clinically appropriate or redundant. (C) 2013 Elsevier Inc. All rights reserved.

AB The effect of duration of cigarette smoking cessation on colorectal cancer risk by molecular subtypes remains unclear. Using duplication-method Cox proportional-hazards regression analyses, we examined associations between duration of smoking cessation and colorectal cancer risk according to status of CpG island methylator phenotype (CIMP), microsatellite instability, v-raf murine sarcoma viral oncogene homolog B1 (BRAF) mutation, or DNA methyltransferase-3B (DNMT3B) expression. Follow-up of 134,204 individuals in 2 US nationwide prospective cohorts (Nurses' Health Study (1980-2008) and Health Professionals Follow-up Study (1986-2008)) resulted in 1,260 incident rectal and colon cancers with available molecular data. Compared with current smoking, 10-19, 20-39, and >= 40 years of smoking cessation were associated with a lower risk of CIMP-high colorectal cancer, with multivariate hazard ratios (95% confidence intervals) of 0.53 (0.29, 0.95), 0.52 (0.32, 0.85), and 0.50 (0.27, 0.94), respectively (P-trend = 0.001), but not with the risk of CIMP-low/CIMP-negative cancer (P-trend = 0.25) (P-heterogeneity = 0.02, between CIMP-high and CIMP-low/CIMP-negative cancer risks). Differential associations between smoking cessation and cancer risks by microsatellite instability (P-heterogeneity = 0.02), DNMT3B expression (P-heterogeneity = 0.03), and BRAF (P-heterogeneity = 0.10) status appeared to be driven by the associations of CIMP-high cancer with microsatellite instability-high, DNMT3B-positive, and BRAF-mutated cancers. These molecular pathological epidemiology data suggest a protective effect of smoking cessation on a DNA methylation-related carcinogenesis pathway leading to CIMP-high colorectal cancer.

AB OBJECTIVES: Inflammatory bowel disease (IBD) and celiac disease are the two most common immune-mediated gastrointestinal diseases. There is limited knowledge regarding the course of IBD in those with coexisting celiac disease. We conducted this study to determine whether patients with coexisting celiac disease present a unique phenotype of IBD and to examine the frequency of co-occurrence of celiac disease and IBD in comparison with other autoimmune disorders.
METHODS: This was a case-control study performed at two tertiary referral centers. Cases comprised of patients with known diagnoses of celiac disease and IBD. Two random IBD controls without celiac disease were selected for each case after matching for IBD type. Disease phenotype and natural history for both Crohn's disease (CD) and ulcerative colitis (UC) were noted from medical record review, and were compared between IBD patients with and without celiac disease.
RESULTS: We identified a total of 51 patients with IBD (22 UC, 1 indeterminate colitis, 28 CD) and celiac disease. There was no significant difference in the age, gender, or ethnicity between celiac-IBD and controls. Pancolitis was more common in celiac-UC patients as compared with controls (odds ratio (OR) 3.30, 95% confidence interval (CI) 1.05-21.50). There was also a trend toward increased use of immunomodulators (IMMs) among celiac-UC patients than in non-celiac UC controls (OR 2.83, 95% CI 0.95-8.48). No phenotypic differences were found in celiac-CD patients. There were no significant differences in IBD-related medication usage, hospitalizations, or surgeries.
CONCLUSIONS: Patients with UC and celiac disease were more likely to have pancolitis and had a trend toward greater use of IMMs. Coexisting celiac disease did not influence natural history of CD.

KNOWLEDGE
AB Background: Although limited health literacy is common in hemodialysis patients, its effects on clinical outcomes are not well understood.
Study Design: Observational study.
Setting & Participants: 260 maintenance hemodialysis patients enrolled in a randomized clinical trial of symptom management strategies from January 2009 through April 2011.
Predictor: Limited health literacy.
Outcomes: Dialysis adherence (missed and abbreviated treatments) and health resource utilization (emergency department visits and end-stage renal disease [ESRD]-related hospitalizations).
Measurements: We assessed health literacy using the Rapid Estimate of Adult Literacy in Medicine (REALM) and used negative binomial regression to analyze the independent associations of limited health literacy with dialysis adherence and health resource utilization over 12-24 months.
Results: 41 of 260 (16%) patients showed limited health literacy (REALM score, <= 60). There were 1,152 missed treatments, 5,127 abbreviated treatments, 552 emergency department visits, and 463 ESRD-related hospitalizations. Limited health literacy was associated independently with an increased incidence of missed dialysis treatments (missed, 0.6% vs 0.3%; adjusted incidence rate ratio [IRR], 2.14; 95% CI, 1.10-4.17), emergency department visits (annual visits, 1.7 vs 1.0; adjusted IRR, 1.37; 95% CI, 1.01-1.86), and hospitalizations related to ESRD (annual hospitalizations, 0.9 vs 0.5; adjusted IRR, 1.55; 95% CI, 1.03-2.34).
Limitations: Generalizability and potential for residual confounding.
Conclusions: Patients receiving maintenance hemodialysis who have limited health literacy are more likely to miss dialysis treatments, use emergency care, and be hospitalized related to their kidney disease. These findings have important clinical practice and cost implications. Am J Kidney Dis. 62(1):73-80. (C) 2013 by the National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

AB PURPOSE: To explore the visual and anatomic outcomes of patients with refractory or recurrent neovascular age-related macular degeneration (AMD) who were converted from bevacizumab and/or ranibizumab to aflibercept.
DESIGN: Two-center, retrospective chart review.
METHODS: Treatment history, visual acuity (VA), and central macular thickness (CMT) on spectral-domain optical coherence tomography were collected. Patients were divided into "refractory" (persistent exudation despite monthly injections) or "recurrent" (exudation suppressed, but requiring frequent injections).
RESULTS: One hundred and two eyes of 94 patients were included; 68 were refractory and 34 were recurrent. Eyes received a mean of 20.4 prior bevacizumab/ranibizumab injections and a mean of 3.8 aflibercept injections. Mean follow-up was 18 weeks. Mean VA was 20/50-1 before conversion, 20/50-2 after 1 aflibercept injection (P = .723), and 20/50 + 2 after the final injection (P = .253). Subgroup analysis of refractory and recurrent cases also showed stable VA. Of the refractory cases, mean CMT had improved after 1 injection (P < .001) and the final injection (P < .001). Intraretinal (P < .001) and subretinal (P < .001) fluid decreased after 1 injection, and the mean injection interval was extended from 5.2 to 6.2 weeks (P = .003). Of the recurrent cases, mean CMT improved after 1 injection (P < .001) and the final injection (P < .001). Intraretinal (P = .003) and subretinal (P = .046) fluid decreased after 1 injection, and the mean injection interval was extended from 7.2 to 9.5 weeks (P = .001).
CONCLUSIONS: Converting patients with chronic neovascular AMD to aflibercept results in stabilized vision and improved anatomic outcomes, while allowing injection intervals to be extended. (C) 2013 by Elsevier Inc. All rights reserved.

AB We previously reported that expression of the transcription factor interferon regulatory factor 1 (IRF1) is an early, critical maladaptive signal expressed by renal tubules during murine ischemic acute kidney injury (AKI). We now show that IRF1 mediates signals from reactive oxygen species (ROS) generated during ischemic AKI and that these signals ultimately result in production of alpha-subtypes of type I interferons (IFN alpha s). We found that genetic knockout of the common type I IFN receptor (IFNARI(-/-)) improved kidney function and histology during AKI. There are major differences in the spatial-temporal production of the two major IFN subtypes, IFN beta and IFN alpha s: IFN beta expression peaks at 4 h, earlier than IFN alpha s, and continues at the same level at 24 h; expression of IFN alpha s also increases at 4 h but continues to increase through 24 h. The magnitude of the increase in IFN alpha s relative to baseline is much greater than that of IFN beta. We show by immunohistology and study of isolated cells that IFN beta is produced by renal leukocytes and IFN alpha s are produced by renal tubules. IRF1, IFN alpha s, and IFNARI were found on the same renal tubules during ischemic AKI. Furthermore, we found that ROS induced IFN alpha expression by renal tubules in vitro. This expression was inhibited by small interfering RNA knockdown of IRF1. Overexpression of IRF1 resulted in the production of IFN alpha s. Furthermore, we found that IFN alpha stimulated production of maladaptive proinflammatory CXCL2 by renal tubular cells. Altogether our data support the following autocrine pathway in renal tubular cells: ROS > IRF1 > IFN alpha > IFNARI > CXCL2.

AB BACKGROUND: Previous non-stage-adjusted research described a lower use of breast-conserving surgery (BCS) for the treatment of breast cancer in the Veterans Health Administration (VHA) facilities than in the private sector.
METHODS: We combined data from the VHA Centralized Cancer Registry with administrative datasets to describe surgical treatment for locoregional breast cancer in VHA facilities from 2000 to 2006.
RESULTS: When considering only procedures performed in VHA facilities, BCS rates decreased from 50.5% (53/105) in 2000 to 42.3% (n = 58/137) in 2006; however, after accounting for procedures conducted in the private sector and paid for by the VHA, BCS rates approached those experienced in breast cancer patients cared for outside the VHA.
CONCLUSIONS: Based solely on procedures performed in the VHA, rates of BCS use are much lower in the VHA than in the private sector. We were able to show similar rates of BCS use when we accounted for procedures paid for by the VHA but performed at an outside facility. Further exploration and prospective analyses to examine these findings are needed. Published by Elsevier Inc.

AB Purpose: Confirmatory factor analysis (CFA) was used to test the hypothesis whether adipocytokines are associated with the risk factor cluster that characterizes the metabolic syndrome (MetS).
Methods: Data from 134 nondiabetic subjects were analyzed using CFA. Insulin sensitivity (Si) was quantified using intravenous glucose tolerance tests, visceral fat area by computed tomography and fasting high-density lipoprotein, triglycerides, monocyte chemoattractant protein-1 (MCP-1), serum amyloid A (SAA), tumor necrosis factor (TNF)-alpha, adiponectin, resistin, leptin, interleukin (IL)-6, C-reactive protein (CRP), and plasminogen activator inhibitor (PAI)-1 were measured.
Results: The basic model representing the MetS included six indicators comprising obesity, SI, lipids, and hypertension, and demonstrated excellent goodness of fit. Using multivariate analysis, MCP-1, SAA, and TNF-alpha were not independently associated with any of the MetS variables. Adiponectin, resistin, leptin, CRP, and IL-6 were associated with at least one of the risk factors, but when added to the basic model decreased all goodness-of-fit parameters. PAI-1 was associated with all cardiometabolic factors and improved goodness-of-fit compared with the basic model.
Conclusions: Addition of PAI-1 increased the CFA model goodness of fit compared with the basic model, suggesting that this protein may represent an added feature of the MetS. Published by Elsevier Inc.

AB Objectives: To describe the development of a strict education protocol to implement the clinical practice guideline "Preservation of Upper Limb Function Following Spinal Cord Injury" into a clinical setting, and evaluate the effect of the protocol on transfer quality.
Design: Randomized controlled trial.
Setting: Acute Model Spinal Cord Injury Systems rehabilitation facility and community.
Participants: Volunteer sample of full-time wheelchair users (N=70) with new spinal cord injuries randomized (1:1) to an intervention and standard-of-care group.
Intervention: The intervention group was educated on transfer skills with a structured protocol implemented by a physical and occupational therapist who were extensively educated on the clinical practice guidelines and current transfer research. The standard-of-care group received standard therapy services.
Main Outcome Measures: Comparison of transfer quality evaluated by the Transfer Assessment Instrument at 4 time points during first year after injury.
Results: No significant differences were found between study groups. Secondary analysis based on type of transfer performed found that participants in the intervention group who performed assisted sitting pivot transfers performed higher-quality transfers (mean +/- SE: 9.43 +/-.55) compared with the standard-of-care group (mean +/- SE: 7.81 +/-.46) (P=.026) at 1 year after discharge. Also, participants who performed a dependent transfer had a higher average score across all 4 time points (mean +/- SE: 9.14 +/-.34) compared with the standard-of-care group (mean +/- SE: 8.09 +/-.29) (P=.019).
Conclusions: For participants who perform assisted or dependent transfers, use of an evidenced-based, structured education program during acute inpatient rehabilitation has the potential to significantly improve the quality of transfers. Further follow-up testing is necessary with a larger sample size to determine the long-term effects. (C) 2013 by the American Congress of Rehabilitation Medicine

AB ObjectiveTo compare cross-sectional and longitudinal side differences in thigh muscle anatomic cross-sectional areas (ACSAs), strength, and specific strength (strength/ACSA) between knees with early versus advanced painful radiographic osteoarthritis in the same person.
MethodsForty-four of 2,678 Osteoarthritis Initiative participants (31 women and 13 men) met the inclusion criteria of bilateral frequent knee pain, medial joint space narrowing (JSN) in 1 knee, and no medial (or lateral) JSN in the contralateral knee. Thigh muscle ACSAs of the quadriceps, hamstrings, adductors, and individual quadriceps heads at consistent locations were determined using magnetic resonance imaging. Isometric muscle strength was determined in extension/flexion (Good Strength Chair). Baseline quadriceps ACSAs and strength were considered primary end points, and longitudinal changes of these factors were considered secondary end points (by paired t-tests).
ResultsNo significant side differences in quadriceps (or other thigh muscle) ACSAs, strength, or specific strength were observed between medial JSN knees versus knees without JSN, or between specific medial JSN knee strata and contralateral knees without JSN, either in men or women. Two-year longitudinal changes in thigh muscle ACSAs and strength were small (5.2%) and did not differ significantly between medial JSN knees and knees without JSN.
ConclusionIn the context of previous findings that side differences in pain are associated with side differences in quadriceps ACSAs, the current results suggest that quadriceps (and other thigh muscle) properties are not independently associated with radiographic disease status (JSN) once knees have reached frequent pain status. Further, our longitudinal findings indicate that a more advanced radiographic stage of knee osteoarthritis is not necessarily associated with a longitudinal decline in muscle function.

AB ObjectiveTotal knee arthroplasty (TKA) is a widely utilized and effective treatment option for end-stage knee osteoarthritis (OA). Knee OA is more prevalent among women compared to men, but there are limited data on the sex differences in surgical outcomes after primary TKA.
MethodsOur sample consisted of all primary TKAs performed in Pennsylvania during the fiscal year 2002. We used International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify major complications and surgical revision. We used mixed-effects logistic regression models to examine the associations between sex and all-cause mortality, readmissions, and major surgical complications. We used proportional hazards models to assess the risk of surgical revision after index arthroplasty. We adjusted for race, age, hospital teaching status, hospital procedure volume, insurance status, and risk of mortality.
ResultsIn 17,994 primary TKAs, there were 46 and 220 deaths at 30 days and 1 year, respectively. Compared to women, men had higher adjusted odds of 1-year mortality (odds ratio [OR] 1.48 [95% confidence interval (95% CI) 1.13-1.94]) after primary TKA. The overall odds of most major 30-day complications did not differ by sex except for surgical wound infections, which were higher in men compared to women (OR 1.31 [95% CI 1.08-1.60]); 30-day readmission was higher in men (OR 1.25 [95% CI 1.10-1.43]). Men had significantly higher rates of revision of index knee arthroplasty at 5 years (hazard ratio 1.20 [95% CI 1.05-1.36]) compared to women.
ConclusionThe higher rates of mortality, hospital readmissions, revision surgery, and wound infections in men undergoing elective primary TKA compared to women indicate there is a sex disparity in these outcomes.

AB ObjectiveTo determine whether there are racial differences in social support among patients with knee osteoarthritis (OA) and whether the impact of social support on patient preferences for total knee replacement (TKR) varies by race and sex.
MethodsA total of 514 white and 285 African American patients with knee OA were surveyed. Logistic regression models were performed to determine if the relationship between willingness to undergo TKR and the interaction of patient race and sex was mediated by social support.
ResultsCompared to whites with knee OA, African American patients were less likely to be married (P < 0.001), reported less close friends/relatives (P < 0.001), and had lower Medical Outcomes Study Social Support Scale (MOS-SSS) scores (P < 0.001). African American patients were also less willing to undergo TKR (62% versus 80%; P < 0.001) than whites. The odds of willingness to undergo TKR were less in white females compared to white males when adjusted for recruitment site, age, income, and the Western Ontario and McMaster Universities Osteoarthritis Index score (odds ratio [OR] 0.57, 95% confidence interval [95% CI] 0.34-0.96). This difference was no longer significant when further adjusted for marital status, number of close friends/relatives, and MOS-SSS score, but the effect size remained unchanged (OR 0.60, 95% CI 0.35-1.02). The odds of willingness to undergo TKR remained much less in African American females (OR 0.35, 95% CI 0.19-0.64) and African American males (OR 0.28, 95% CI 0.14-0.54) compared to white males when controlled for sociodemographic, clinical, and social support measures.
ConclusionAfrican American patients reported less structural and functional social support than whites. Social support is an important determinant of preference for TKR surgery only among whites.

AB PURPOSE: To evaluate clinical outcomes of CT-guided high-dose-rate (HDR) interstitial brachy-therapy for primary and recurrent gynecologic cancer.
METHODS AND MATERIALS: Records were reviewed for 68 women (34 with primary disease and 34 with recurrence) treated with CT-guided HDR interstitial brachytherapy between May 2005 and September 2011. Interstitial application was performed under general anesthesia using an iterative approach of catheter insertion and adjustment with serial image acquisition by CT in a dedicated brachytherapy suite. The median fractional brachytherapy dose was 3.9 Gy delivered twice daily in seven fractions. The median cumulative dose in equivalent 2-Gy fractions was 74.8 Gy. Actuarial survival estimates were calculated using the Kaplan-Meier method, and toxicity was reported by Common Toxicity Criteria.
RESULTS: Primary disease sites were endometrial (34), cervical (17), vaginal (11), ovarian (3), and vulvar (3). Median age was 61.5 years, and tumor size at diagnosis was 3.4 cm. Median D-90 and V-100 were 73.6 Gy and 87.5%, respectively; median D-2cc for bladder, rectum, and sigmoid were 67.1, 64.6, and 53.7 Gy, respectively. With a median followup of 17 months, actuarial rates of local control, progression-free survival, and overall survival at 2 years for all patients were 86%, 60%, and 64%, respectively. There were 9 grade 3 late toxicities (six gastrointestinal and three vulvovaginal).
CONCLUSIONS: HDR interstitial brachytherapy with CT-guided catheter placement results in acceptable local control, toxicity, and survival rates for women with primary or recurrent gynecologic cancer. Durable pelvic control may be achieved in most patients with this specialized brachytherapy technique. (C) 2013 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

AB The hippocampus is classically involved in memory consolidation, spatial navigation and is involved in the stress response. Migraine is an episodic disorder characterized by intermittent attacks with a number of physiological and emotional stressors associated with or provoking each attack. Given that migraine attacks can be viewed as repeated stressors, alterations in hippocampal function and structure may play an important role in migraine pathophysiology. Using high-resolution magnetic resonance imaging, hippocampal morphometric and functional differences (in response to noxious heat stimulation) were compared in age and gender-matched acute episodic migraineurs with high (HF) versus low (LF) frequency of migraine attacks. Morphometric results were compared with age and gender-matched healthy control (HC) cohort. Significant larger bilateral hippocampal volume was found in LF group relative to the HF and HC groups suggestive of an initial adaptive plasticity that may then become dysfunctional with increased frequency. Functional correlates of greater deactivation (LF > HF) in the same hippocampal regions in response to noxious stimulation was also accompanied by overall reduction in functional connectivity of the hippocampus with other brain regions involved in pain processing in the HF group. The results implicate involvement of hippocampus in the pathophysiology of the migraine.

AB Based on high-resolution diffusion tensor magnetic resonance imaging (DTI) tractographic analyses in 39 healthy adult subjects, we derived patterns of connections and measures of volume and biophysical parameters, such as fractional anisotropy (FA) for the human middle longitudinal fascicle (MdLF). Compared to previous studies, we found that the cortical connections of the MdLF in humans appear to go beyond the superior temporal (STG) and angular (AG) gyri, extending to the temporal pole (TP), superior parietal lobule (SPL), supramarginal gyrus, precuneus and the occipital lobe (including the cuneus and lateral occipital areas). Importantly, the MdLF showed a striking lateralized pattern with predominant connections between the TP, STG and AG on the left and TP, STG and SPL on the right hemisphere. In light of the results of the present study, and of the known functional role of the cortical areas interconnected by the MdLF, we suggested that this fiber pathway might be related to language, high order auditory association, visuospatial and attention functions.

AB Fat necrosis of the breast is increasingly reported and used as a trial endpoint in the treatment of breast cancer with accelerated partial breast irradiation (APBI). Yet, there is no universal toxicity scoring system within the latest version of the Common Terminology Criteria for Adverse Events (CTCAE v4.0). This requires investigators to adopt their own scoring system or improperly use those that exist, and limits accurate reporting of this entity. Fat necrosis of the breast also creates diagnostic uncertainty among clinicians and concern of recurrence among patients. In this review, we address the question of increasing incidence of fat necrosis through the comparison of recent APBI trials and literature. The pathogenesis, symptoms, clinical and radiologic diagnosis, clinical predictors of developing fat necrosis, management and follow-up are also discussed. Lastly, we propose a simplified and universal scoring system for the reporting of fat necrosis.

AB Treatment for breast cancer may result in the formation of palpable cords in the axillary region. Our aim was to evaluate cording incidence, risk factors, and association with upper extremity functional impairment and measured arm volume change. We included 308 patients with unilateral breast cancer prospectively screened for upper extremity lymphedema, symptoms and function. Patients were assessed pre- and post-operatively and at 3-8-month intervals with perometer arm measurements and the LEFT-BC questionnaire. Cording was determined by patient self-report. The cumulative incidence of cording and its association with clinicopathologic factors, upper extremity functional impairment, and measured arm volume change were analyzed. 31.5 % (97/308) of patients reported cording, with a cumulative incidence of 36.2 % at 24 months post-operative. Clinicopathologic factors significantly associated with cording by multivariate analysis included axillary lymph node dissection (p < 0.0001) and younger age at diagnosis (p = 0.0005). Cording was associated with increased functional impairment (p = 0.0018) and an arm volume increase of a parts per thousand yen5 % (p = 0.028). Cording following breast cancer treatment is common, and may occur beyond the post-operative period. Our findings emphasize the importance of identifying patients at high risk for cording, and developing strategies to minimize functional impairment and arm volume elevation associated with cording. Future studies should investigate the effectiveness of interventions for cording following breast cancer treatment.

AB Cancer risk prediction tools provide valuable information to clinicians but remain computationally challenging. Many clinics find that CaGene or HughesRiskApps fit their needs for easy- and ready-to-use software to obtain cancer risks; however, these resources may not fit all clinics' needs. The HughesRiskApps Group and BayesMendel Lab therefore developed a web service, called "Risk Service", which may be integrated into any client software to quickly obtain standardized and up-to-date risk predictions for BayesMendel tools (BRCAPRO, MMRpro, PancPRO, and MelaPRO), the Tyrer-Cuzick IBIS Breast Cancer Risk Evaluation Tool, and the Colorectal Cancer Risk Assessment Tool. Software clients that can convert their local structured data into the HL7 XML-formatted family and clinical patient history (Pedigree model) may integrate with the Risk Service. The Risk Service uses Apache Tomcat and Apache Axis2 technologies to provide an all Java web service. The software client sends HL7 XML information containing anonymized family and clinical history to a Dana-Farber Cancer Institute (DFCI) server, where it is parsed, interpreted, and processed by multiple risk tools. The Risk Service then formats the results into an HL7 style message and returns the risk predictions to the originating software client. Upon consent, users may allow DFCI to maintain the data for future research. The Risk Service implementation is exemplified through HughesRiskApps. The Risk Service broadens the availability of valuable, up-to-date cancer risk tools and allows clinics and researchers to integrate risk prediction tools into their own software interface designed for their needs. Each software package can collect risk data using its own interface, and display the results using its own interface, while using a central, up-to-date risk calculator. This allows users to choose from multiple interfaces while always getting the latest risk calculations. Consenting users contribute their data for future research, thus building a rich multicenter resource.

AB The discovery that some melanoma tumours harbour mutations in the BRAF gene (e.g. V600E) and the subsequent development of specific BRAF inhibitors have greatly improved the treatment of metastatic melanoma. Resistance of tumour cells to BRAF inhibitors is reduced by the addition of an MEK inhibitor; both BRAF and MEK inhibitors have been reported to produce a variety of dermatological toxic effects. Benign naevi often harbour BRAF mutations but few reports exist that document the response of naevus cells to BRAF inhibition. We report sarcoidal-type granulomatous inflammation in two patients with metastatic melanoma undergoing treatment with combination BRAF and MEK inhibitor therapy. This inflammation manifested in one patient as a nonspecific papular eruption; in the other, in association with clinical regression of multiple benign-appearing naevi during the course of therapy. The significance of sarcoidal-type inflammation occurring during treatment of metastatic melanoma with a combination of BRAF and MEK inhibitors is unclear. Its association with the clinical regression of benign-appearing naevi suggests a possible exaggerated inflammatory response to degenerating naevus cells in these lesions.

AB Multiple myeloma (MM) is an incurable neoplasm caused by proliferation of malignant plasma cells in the bone marrow (BM). MM is characterized frequently by a complete or partial deletion of chromosome 13q14, seen in more than 50% of patients at diagnosis. Within this deleted region the tripartite motif containing 13 (TRIM13, also termed RFP2) gene product has been proposed to be a tumour suppressor gene (TSG). Here, we show that low expression levels of TRIM13 in MM are associated with chromosome 13q deletion and poor clinical outcome. We present a functional analysis of TRIM13 using a loss-of-function approach, and demonstrate that TRIM13 downregulation decreases tumour cell survival as well as cell cycle progression and proliferation of MM cells. In addition, we provide evidence for the involvement of TRIM13 downregulation in inhibiting the NF kappa B pathway and the activity of the 20S proteasome. Although this data does not support a role of TRIM13 as a TSG, it substantiates important roles of TRIM13 in MM tumour survival and proliferation, underscoring its potential role as a novel target for therapeutic intervention.

AB Despite the difficulty in clearly defining and measuring spirituality, a growing literature describes its importance in oncology and survivorship. Religious/spiritual beliefs influence patients' decision-making with respect to both complementary therapies and aggressive care at the end of life. Measures of spirituality and spiritual well-being correlate with quality of life in cancer patients, cancer survivors, and caregivers. Spiritual needs, reflective of existential concerns in several domains, are a source of significant distress, and care for these needs has been correlated with better psychological and spiritual adjustment as well as with less aggressive care at the end of life. Studies show that while clinicians such as nurses and physicians regard some spiritual care as an appropriate aspect of their role, patients report that they provide it infrequently. Many clinicians report that their religious/spiritual beliefs influence their practice, and practices such as mindfulness have been shown to enhance clinician self-care and equanimity. Challenges remain in the areas of conceptualizing and measuring spirituality, developing and implementing training for spiritual care, and coordinating and partnering with chaplains and religious communities.

Analysis of whole-exome sequencing data from 151 tumors revealed the phosphoinositide 3-kinase (PI3K) pathway to be the most frequently mutated oncogenic pathway (30.5%). PI3K pathway-mutated HNSCC tumors harbored a significantly higher rate of mutations in known cancer genes. In a subset of human papillomavirus-positive tumors, PIK3CA or PIK3R1 was the only mutated cancer gene. Strikingly, all tumors with concurrent mutation of multiple PI3K pathway genes were advanced (stage IV), implicating concerted PI3K pathway aberrations in HNSCC progression. Patient-derived tumorgrafts with canonical and noncanonical PIK3CA mutations were sensitive to an mTOR/PI3K inhibitor (BEZ-235), in contrast to PIK3CA-wild-type tumorgrafts. These results suggest that PI3K pathway mutations may serve as predictive biomarkers for treatment selection.
SIGNIFICANCE: Treatment options for HNSCC are limited, in part, because of an incomplete understanding of the targetable mutations that "drive" tumor growth. Here, we define a subgroup of HNSCC harboring activating mutations of genes in the PI3K pathway where targeting the pathway shows antitumor efficacy. These results suggest that PI3K pathway mutation assessment may be used to guide HNSCC therapy. (C) 2013 AACR.

AB Critically short telomeres activate cellular senescence or apoptosis, as mediated by the tumor suppressor p53, but in the absence of this checkpoint response, telomere dysfunction engenders chromosomal aberrations and cancer. Here, analysis of p53-regulated genes activated in the setting of telomere dysfunction identified Zfp365 (ZNF365 in humans) as a direct p53 target that promotes genome stability. Germline polymorphisms in the ZNF365 locus are associated with increased cancer risk, including those associated with telomere dysfunction. On the mechanistic level, ZNF365 suppresses expression of a subset of common fragile sites, including telomeres. In the absence of ZNF365, defective telomeres engage in aberrant recombination of telomere ends, leading to increased telomere sister chromatid exchange and formation of anaphase DNA bridges, including ultra-fine DNA bridges, and ultimately increased cytokinesis failure and aneuploidy. Thus, the p53-ZNF365 axis contributes to genomic stability in the setting of telomere dysfunction.
SIGNIFICANCE: The contribution of the p53-ZNF365-telomere axis in the suppression of genomic instability illuminates how alterations in this pathway may confer increased cancer risk for individuals harboring germline alterations in the ZNF365 locus. (C) 2013 AACR.

INFORMATION; MOTHERS
AB Background: Although BRCA1/2 genetic testing is discouraged in minors, mothers may disclose their own results to their children. Factors affecting patients' disclosure decisions and patient outcomes of disclosure are largely unknown. Methods: Mothers (N = 221) of children aged 8 to 21 years enrolled in this prospective study of family communication about cancer genetic testing. Patients underwent BRCA1/2 genetic counseling and testing, and completed standardized behavioral assessments before and 1-month following receipt of their results.
Results: Most patients (62.4%) disclosed BRCA1/2 test results to their child. Patients were more likely to disclose if they received negative or uninformative versus positive results [OR = 3.11; 95% confidence interval (CI), 1.11-8.71; P = .03], their child was 13 years of age or more versus younger (OR = 5.43; 95% CI, 2.18-13.53; P < .001), and as the ratio of patients' perceived benefits of disclosure outweighed potential risks (OR - 2.40; 95% CI, 1.63-3.54; P < .001). Postdecision satisfaction about disclosure was lowest among nondisclosing patients (P < .001) and those reporting greater decisional conflict (P < .001).
Conclusions: Patients commonly discuss their BRCA1/2 results with their teenage and young adult children, especially if the information is perceived as beneficial. Satisfaction with disclosure decision making remains lowest among nondisclosing and conflicted patients. Family communication decision support adjuncts to genetic counseling are needed to help ameliorate these effects.
Impact: This study describes the prevalence of family communication about maternal BRCA1/2 genetic testing with minor children, and decisions and outcomes of disclosure. (c) 2013 AACR.

AB The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is the isotropic stress exerted by the fluid phase. We recently showed that growth-induced solid stress is on the order of 1.3 to 13.0 kPa (10-100 mmHg) - high enough to cause compression of fragile blood vessels, resulting in poor perfusion and hypoxia. However, the evolution of growth-induced stress with tumor progression and its effect on cancer cell proliferation in vivo is not understood. To this end, we developed a mathematical model for tumor growth that takes into account all three types of stresses: growth-induced stress, externally applied stress, and fluid pressure. First, we conducted in vivo experiments and found that growth-induced stress is related to tumor volume through a biexponential relationship. Then, we incorporated this information into our mathematical model and showed that due to the evolution of growth-induced stress, total solid stress levels are higher in the tumor interior and lower in the periphery. Elevated compressive solid stress in the interior of the tumor is sufficient to cause the collapse of blood vessels and results in a lower growth rate of cancer cells compared with the periphery, independently from that caused by the lack of nutrients due to vessel collapse. Furthermore, solid stress in the periphery of the tumor causes blood vessels in the surrounding normal tissue to deform to elliptical shapes. We present histologic sections of human cancers that show such vessel deformations. Finally, we found that fluid pressure increases with tumor growth due to increased vascular permeability and lymphatic impairment, and is governed by the microvascular pressure. Crucially, fluid pressure does not cause vessel compression of tumor vessels. (C) 2013 AACR.

AB Mutations in PIK3CA, the gene encoding the p110 alpha catalytic subunit of phosphoinositide 3-kinase (PI3K), have been shown to transform mammary epithelial cells (MEC). Studies suggest this transforming activity requires binding of mutant p110a via p85 to phosphorylated YXXM motifs in activated receptor tyrosine kinases (RTK) or adaptors. Using transgenic mice, we examined if ErbB3, a potent activator of PI3K, is required for mutant PIK3CA-mediated transformation of MECs. Conditional loss of ErbB3 in mammary epithelium resulted in a delay of PIK3CA(H1047R)-dependent mammary gland hyperplasia, but tumor latency, gene expression, and PI3K signaling were unaffected. In ErbB3-deficient tumors, mutant PI3K remained associated with several tyrosyl phosphoproteins, potentially explaining the dispensability of ErbB3 for tumorigenicity and PI3K activity. Similarly, inhibition of ErbB RTKs with lapatinib did not affect PI3K signaling in PIK3CA(H1047R)-expressing tumors. However, the p110a-specific inhibitor BYL719 in combination with lapatinib impaired mammary tumor growth and PI3K signaling more potently than BYL719 alone. Furthermore, coinhibition of p110a and ErbB3 potently suppressed proliferation and PI3K signaling in human breast cancer cells harboring PIK3CA(H1047R). These data suggest that PIK3CA(H1047R)-driven tumor growth and PI3K signaling can occur independently of ErbB RTKs. However, simultaneous blockade of p110 alpha and ErbB RTKs results in superior inhibition of PI3K and mammary tumor growth, suggesting a rational therapeutic combination against breast cancers harboring PIK3CA activating mutations.

AB Desirudin, a subcutaneously (SC) administered direct thrombin inhibitor, is indicated for prevention of venous thromboembolic events (VTEs) after total joint replacement surgery. DESIR-ABLE (multicenter trial of desirudin for the prophylaxis of thrombosis: an alternative to heparin-based anticoagulation) was a multicenter, open-label, single-arm study of hospitalized patients requiring VTE protection designed to extend the safety profile for desirudin to include a broad population of perioperative/critically ill patients. The primary end point was major bleeding. A total of 516 patients undergoing major surgery (378, 73%) or who were medically ill with prolonged immobility (138, 27%) were enrolled at 19 centers and received desirudin 15 mg Q12H. Many patients had high-risk features for bleeding and thrombosis such as thrombocytopenia (<100x10(9)/mL, n = 50), severe obesity (body mass index >35, n = 145), and renal impairment (creatinine clearance <60 mL/min, n = 292). There were no major bleeds and no VTE-related deaths in this study. The DESIR-ABLE demonstrated the safety of desirudin in critically ill perioperative and medical patients. Trials in specific surgical or medically ill patients are needed to confirm these findings.

AB Background and objective Calcific uremic arteriolopathy (CUA) is an often fatal condition with no effective treatment. Multiple case reports and case series have described intravenous sodium thiosulfate (STS) administration in CUA, but no studies have systematically evaluated this treatment.
Design, setting, participants, & measurements This study included 172 patients undergoing maintenance hemodialysis who had CUA and were treated with STS between August 2006 and June 2009 at Fresenius Medical Care North America. Of these, 85% completed STS therapy. Clinical, laboratory, and mortality data were abstracted from clinical information systems. Responses to survey questionnaires sent to treating physicians regarding patient-level outcomes were available for 53 patients. Effect on CUA lesions and mortality were summarized as CUA outcomes. Relevant laboratory measures, weight (using pairwise comparisons of values before, during, and after STS), and adverse events were summarized as safety parameters.
Results Mean age of the cohort was 55 years, and 74% of patients were women. Median STS dose was 25 g, and median number of doses was 38. Among surveyed patients, CUA completely resolved in 26.4%, markedly improved in 18.9%, improved in 28.3%, and did not improve in 5.7%; in the remaining patients (20.8%), the response was unknown. One-year mortality in patients treated with STS was 35%. Adverse events, laboratory abnormalities, and weight-related changes were mild. Significant reductions in serum phosphorous (P=0.02) and parathyroid hormone (P=0.01) were noted during STS treatment in patients who completed the therapy.
Conclusions Although conclusive evidence regarding its efficacy is lacking, a majority of patients who received STS demonstrated clinical improvement in this study.

AB Background and objectives Patterns of end-of-life care among patients with ESRD differ by race. Whether the magnitude of racial differences in end-of-life care varies across regions is not known.
Design, setting, participants, & measurements This observational cohort study used data from the US Renal Data System and regional health care spending patterns from the Dartmouth Atlas of Healthcare. The cohort included 101,331 black and white patients 18 years and older who initiated chronic dialysis or received a kidney transplant between June 1, 2005, and September 31, 2008, and died before October 1, 2009. Black white differences in the odds of in-hospital death, dialysis discontinuation, and hospice referral by quintile of end-of-life expenditure index (EOL-EI) were examined.
Results In adjusted analyses, the odds ratios for dialysis discontinuation for black versus white patients ranged from 0.47 (95% confidence interval=0.43 to 0.51) in the highest quintile of EOL-EI to 0.63 (95% confidence interval=0.54 to 0.74) in the lowest quintile (P for interaction<0.001). Hospice referral ranged from 0.55 (95% confidence interval:=0.50 to 0.60) in the highest quintile of EOL-EI to 0.82(95% confidence interval=0.69 to 0.96) in the lowest quintile (P for interaction<0.001). The association of race with in-hospital death also differed in magnitude across quintiles of EOL-EI, ranging from 1.21 (95% confidence interval=1.08 to 1.35) in the highest quintile of EOL-EI to 1.47 (95% confidence interval=1.27 to 1.71) in the second quintile (P for interaction<0.001).
Conclusions There are pronounced black white differences in patterns of hospice referral and dialysis discontinuation among patients with ESRD that vary substantially across regions of the United States.

AB Background and objectives Higher morning serum phosphorus has been associated with cardiovascular disease (CVD) in patients with or without CKD. In patients with CKD and a phosphorous level >4.6 mg/dl, the Kidney Disease Improving Global Outcomes guidelines recommend dietary phosphorus restriction. However, whether phosphorus restriction influences serum phosphorus concentrations and whether dietary phosphorus is itself associated with CVD or death are uncertain.
Design, setting, participants, & measurements Among 880 patients with stable CVD and normal kidney function to moderate CKD, 24-hour urine phosphorus excretion (UPE) and serum phosphorus were measured at baseline. Participants were followed for a median. of 7.4 years for CVD events and all-cause mortality.
Results Mean +/- SD age was 67 +/- 11 years, estimated GFR (eGFR) was 71 +/- 22 ml/min per 1.73 m(2), and serum phosphorus was 3.7 +/- 0.6 mg/dl. Median UPE was 632 (interquartile range, 439, 853) mg/d. In models adjusted for demographic characteristics and eGFR, UPE was weakly and nonsignificantly associated with serum phosphorus (0.03 mg/dl higher phosphorus per 300 mg higher UPE; P=0.07). When adjusted for demographics, eGFR, and CVD risk factors, each 300-mg higher UPE was associated with 17% lower risk of CVD events. The association of UPE with all-cause mortality was not statistically significant (hazard ratio, 0.93; 95% confidence interval, 0.82 to 1.05). Results were similar irrespective of CKD status (P interactions > 0.87).
Conclusions Among outpatients with stable CVD, the magnitude of the association of UPE with morning serum phosphorus is modest. Greater UPE is associated with lower risk for CVD events. The association was similar for all-cause mortality but was not statistically significant.

AB The association between exposure to multiple potentially traumatic events (PTEs) and subsequent increased risk of post-traumatic stress disorder (PTSD) is well established. However, less is known about the relation between exposure to numerous PTEs, as is typical with military service, and treatment outcome. Furthermore, there has been little research examining military specific protective factors, such as pre-deployment preparedness, on PTSD treatment response. The current study investigated combat exposure and potential moderators of treatment outcome for exposure therapy in Operation Enduring Freedom/ Operation Iraqi Freedom (OEF/OIF) veterans with PTSD. One hundred and eleven OEF/OIF veterans diagnosed with PTSD participated in 8weeks of exposure therapy. Results indicated that increased combat exposure was associated with a reduced rate of change in PTSD symptoms but not depression symptoms. These findings were consistent across two measures of combat exposure. There was preliminary support for the moderating effect of pre-deployment preparedness on the association between combat exposure and treatment response. Together, these findings suggest that increased combat exposure is associated with poor treatment response in veterans with PTSD; however, this can be reduced by elevated pre-deployment preparedness.

Key Practitioner Message:
Increased combat exposure is associated with poorer treatment response.
Pre-deployment training is associated with improved treatment response.
PTSD interventions should account for the frequency of combat in military personnel.

AB BACKGROUND Superficial basal cell carcinomas (BCC) are often considered a non-aggressive form of skin cancer, most often found on the trunk in younger patients.
OBJECTIVE To determine the characteristics of superficial BCC of the head and neck.
MATERIALS AND METHODS A retrospective review of patients undergoing Mohs micrographic surgery (MMS) for the treatment of a purely superficial BCC on the head and neck region was performed.
RESULTS Superficial BCC occurred more commonly in women (66.5%) than men (33.5%), most often on chronically sun-exposed skin such as the central face and nose. Women developed superficial BCC at a younger age than men (58 vs 63 years old, p = 0.02). The clinical sizes of the tumors were significantly smaller than the final Mohs defects for all locations on the head and neck, excluding ears and scalp. Recurrence rates after MMS were 3.6% despite negative histologic margins at the time of surgery.
CONCLUSION Superficial BCC are a unique subtype of BCC that tend to occur in younger patients, particularly women. Mohs surgeons need to be familiar with these tumors on the head and neck given their propensity for skip-lesions, higher recurrence rates, and significantly larger defect sizes than would be expected clinically.

AB BACKGROUND The use of carbon dioxide (CO2) laser-mediated ablative fractional resurfacing (AFR) is currently under extensive clinical investigation, but the molecular mechanisms underlying this process are unclear.
OBJECTIVES To determine the early expressed genes that are upregulated in human skin after treatment using a CO2 fractional laser.
METHODS Whole human skin was irradiated using an AFR CO2 laser, and changes in gene expression after 2 and 24 hours were analyzed using microarray analysis. The results were validated using reverse transcriptase polymerase chain reaction (RT-PCR). Laser scanning confocal microscopy (LSCM) was used to investigate the expression of the validated proteins after AFR CO2 laser treatment of skin that had been biopsied from seven Korean patients.
RESULTS Gene expression profiling showed that the most significantly upregulated genes in these skin samples were those encoding Wnt5a, cysteine-rich angiogenic inducer 61 (CYR61), and heat shock protein (HSP) 90. These results were confirmed using real-time RT-PCR and LSCM.
CONCLUSIONS Irradiation using an AFR laser may induce the expression of Wnt5a, CYR61, and HSP90 in human skin during the early remodeling phases, suggesting that the induction of proteins may be the preceding event that is associated with the clinical effects of laser treatment.

AB Abdominal abscesses are a common complication in Crohn's disease (CD). Percutaneous drainage of such abscesses has become increasingly popular and may deliver outcomes comparable to surgical treatment; however, such comparative data are limited from single-center studies. There have been no nationally representative studies comparing different treatment modalities for abdominal abscesses.
We identified all adult CD-related non-elective hospitalizations from the Nationwide Inpatient Sample 2007 that were complicated by an intra-abdominal abscess. Treatment modality was categorized into 3 strata-medical treatment alone, percutaneous drainage, and surgery. We analyzed the nationwide patterns in the treatment and outcomes of each treatment modality and examined for patient demographic, disease, or hospital-related disparities in treatment and outcome.
There were an estimated 3,296 hospitalizations for abdominal abscesses in patients with CD. Approximately 39 % were treated by medical treatment alone, 29 % with percutaneous drainage, and 32 % with surgery with a significant increase in the use of percutaneous drainage since 1998 (7 %). Comorbidity burden, admission to a teaching hospital, and complicated Crohn's disease (fistulae, stricture) were associated with non-medical treatment. Use of percutaneous drainage was more common in teaching hospitals. Mean time to percutaneous drainage and surgical treatment were 4.6 and 3.3 days, respectively, and early intervention was associated with significantly shorter hospitalization.
We describe the nationwide pattern in the treatment of abdominal abscesses and demonstrate an increase in the use of percutaneous drainage for the treatment of this subgroup. Early treatment intervention was predictive of shorter hospitalization.

RECOMMENDATIONS; QUANTIFICATION; GUIDELINES; AFTERLOAD
AB There is uncertainty in identifying patients with severe aortic stenosis (AS) with preserved left ventricular (LV) ejection fraction, low flow, and low gradients (LFLG). Prior studies propose that these patients demonstrate significant concentric remodelling and decreased survival, while others suggest that they have features and survival similar to moderate AS.
We compared the clinical characteristics, echocardiographic features, and overall survival of LFLG AS patients (n 38) to those with normal-flow, low-gradient (NFLG) severe AS (n 75) and moderate AS (n 70). Low-flow, low-gradient patients had the lowest end-diastolic volume index (43 vs. 54 vs. 54 mL/m(2), P 0.001), highest relative wall thickness (RWT) (60 vs. 49 vs. 48, P 0.001), and lowest septal mitral annular displacement (1.0 vs. 1.5 vs. 1.5 cm, P 0.001). New York Heart Association (NYHA) class III/IV symptoms were the most frequent in the LFLG group (29 vs. 11 vs. 3, P 0.001). Survival at 3 years was significantly lower in LFLG compared with NFLG (P 0.006) and moderate AS (P 0.002), but not different between NFLG and moderate AS (P 0.49). Higher NYHA classification (HR 1.77, 95 CI 1.222.57), RWT 50 (HR 3.28, 95 CI 1.338.1), and septal displacement 1.1 cm (HR 3.93, 95 CI 1.967.82) but not low flow were independent predictors of survival in Cox proportional hazards analysis.
Preserved ejection fraction, LFLG AS patients exhibit marked concentric remodelling and impaired longitudinal functionalufeatures that predict their poor long-term survival. Normal-flow, low-gradient AS patients have outcomes similar to moderate AS.

AB We recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts development of CVD and its functional consequences.
We performed a matched casecontrol study derived from the population-based Malm Diet and Cancer Cardiovascular Cohort (MDC-CC), all free of CVD. During 12 years of follow-up, 253 individuals developed CVD and were matched for age, sex, and Framingham risk score with 253 controls. Amino acids were profiled in baseline plasma samples, using liquid chromatography-tandem mass spectrometry, and relationship to incident CVD was assessed using conditional logistic regression. We further examined whether the amino acid score also correlated with anatomical [intima-media thickness (IMT) and plaque formation] and functional (exercise-induced myocardial ischaemia) abnormalities. Compared with the lowest quartile of the DM-AA score, the odds ratio (95 confidence interval) for incident CVD in subjects belonging to quartiles 2, 3, and 4 was 1.27 (0.722.22), 1.96 (1.073.60), and 2.20 (1.124.31) (P-trend 0.010), respectively, after multivariate adjustment. Increasing quartile of the DM-AA score was cross-sectionally related to carotid IMT (P-trend 0.037) and with the presence of at least one plaque larger than 10 mm(2) (P-trend 0.001). Compared with the lowest quartile of the DM-AA score, the odds ratio (95 confidence interval) for inducible ischaemia in subjects belonging to quartiles 2, 3, and 4 was 3.31 (1.0510.4), 4.24 (1.3613.3), and 4.86 (1.4716.1) (P-trend 0.011), respectively.
This study identifies branched-chain and aromatic amino acids as novel markers of CVD development and as an early link between diabetes and CVD susceptibility.

AB Aims Left ventricular (LV) lead positioning for cardiac resynchronization therapy (CRT) is largely empirical and operator-dependent. Our aim was to determine whether cardiac magnetic resonance (CMR)-guided CRT may improve the acute and the chronic response.
Methods CMR-derived anatomical models and dyssynchrony maps were created for 20 patients. The CMR targets (three latest and results activated segments with <50% scar) were overlaid on to live fluoroscopy. Acute haemodynamic response (AHR) to LV pacing was assessed using an intra-ventricular pressure wire. Chronic CRT response (end-systolic volume reduction >= 15%) was assessed 6 months post-implantation. All patients underwent successful CMR-guided LV lead placement. A CMR target segment was paced in 75% of patients. The mean change in LVdP/dt(max) for the CMR target was +14.2 +/- 12.5 vs. +18.7 +/- 11.9% for the best AHR in any segment and +12.0 +/- 13.8% for the segment based on coronary sinus (CS) venography. Using CMR guidance, the acute responder rate was 60 vs. 50% on the basis of venography. At 6 months 60% of patients were echocardiographic responders. Of the echocardiographic responders, 92% were successfully paced in a CMR target segment compared with only 50% of non-responders (P = 0.04).
Conclusion CMR guidance compared well when validated against the AHR. Lead placement was possible in the CMR target region in most patients with an AHR comparable with the best achieved in any CS branch. The chronic response was significantly better in patients paced in a CMR target segment. These results suggest that CMR guidance may represent a clinically useful tool for CRT.

AB Nearly one-third of patients with obsessive-compulsive disorder (OCD) fail to respond to adequate therapeutic approaches such as serotonin reuptake inhibitors and/or cognitive-behavioral therapy (CBT). This study investigated structural magnetic resonance imaging (MRI) correlates as potential pre-treatment brain markers to predict treatment response in treatment-naive OCD patients randomized between trials of fluoxetine or CBI Treatment-naive OCD patients underwent structural MRI scans before randomization to a 12-week clinical trial of either fluoxetine or group-based CBT. Voxel-based morphometry was used to identify correlations between pretreatment regional gray matter volume and changes in symptom severity on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Brain regional correlations of treatment response differed between treatment groups. Notably, symptom improvement in the fluoxetine treatment group (n=14) was significantly correlated with smaller pretreatment gray matter volume within the right middle lateral orbitofrontal cortex (OFC), whereas symptom improvement in the CBT treatment group (n=15) was significantly correlated with larger pretreatment gray matter volume within the right medial prefrontal cortex (mPFC). No significant a priori regional correlations of treatment response were identified as common between the two treatment groups when considering the entire sample (n=29). These findings suggest that pretreatment gray matter volumes of distinct brain regions within the lateral OFC and mPFC were differentially correlated to treatment response to fluoxetine versus CBT in OCD patients. This study further implicates the mPFC in the fear/anxiety extinction process and stresses the importance of lateral portions of the OFC in mediating fluoxetine's effectiveness in OCD.

AB Leptin, a peptide hormone from adipose tissue and key player in weight regulation, has been suggested to be involved in sleep and cognition and to exert antidepressant-like effects, presumably via its action on the HPA-axis and hippocampal function. This led us to investigate whether genetic variants in the leptin gene, the level of leptin mRNA-expression and leptin serum concentrations are associated with response to antidepressant treatment. Our sample consisted of inpatients from the Munich Antidepressant Response Signature (MARS) project with weekly Hamilton Depression ratings, divided into two subsamples. In the exploratory sample (n=251) 17 single nucleotide polymorphisms (SNPs) covering the leptin gene region were genotyped. We found significant associations of several SNPs with impaired antidepressant treatment outcome and impaired cognitive performance after correction for multiple testing. The SNP (rs10487506) showing the highest association with treatment response (p=3.9 x 10(-5)) was analyzed in the replication sample (n=358) and the association could be verified (p=0.021) with response to tricyclic antidepressants. In an additional meta-analysis combining results from the MARS study with data from the Genome-based Therapeutic Drugs for Depression (GENDEP) and the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) studies, nominal associations of several polymorphisms in the upstream vicinity of rs10487506 with treatment outcome were detected (p=0.001). In addition, we determined leptin mRNA expression in lymphocytes and leptin serum levels in subsamples of the MARS study. Unfavorable treatment outcome was accompanied with decreased leptin mRNA and leptin serum levels. Our results suggest an involvement of leptin in antidepressant action and cognitive function in depression with genetic polymorphisms in the leptin gene, decreased leptin gene expression and leptin deficiency in serum being risk factors for resistance to antidepressant therapy in depressed patients.

AB Blood flow (BF) in many tissues is stable during significant fluctuations in systemic arterial blood pressure or perfusion pressure under normal conditions. The regulatory mechanisms responsible for this non-passive BF behavior include both local and neural control mechanisms. This study evaluated cerebral BF (CBF), retinal BF (RBF) and choroidal BF (ChBF) responses to acute blood pressure increases in rats using magnetic resonance imaging (MRI). A transient increase in blood pressure inside the MRI scanner was achieved by mechanically inflating a balloon catheter to occlude the descending aorta near the diaphragm. We verified the rat model of mechanical occlusion and MRI approach by first measuring blood-flow regulatory responses to changing BP in the brain under normoxia and hypercapnia where the phenomenon is well documented. Retinal and choroidal blood-flow responses to transient increased arterial pressure were then investigated. In response to an acute increase in blood pressure, RBF exhibited autoregulatory behavior and ChBF exhibited baroregulation similar to that seen in the cerebral circulation. This approach may prove useful to investigate retinal and choroidal vascular dysregulation in rat models of retinal diseases with suspected vascular etiology. (C) 2013 Elsevier Ltd.

AB Selectins are carbohydrate-binding adhesion molecules that are critically involved in leukocyte recognition of endothelium. The endothelial selectins have been implicated in homing of hematopoietic stem and progenitor cells (HSPCs) to the bone marrow (BM) during bone marrow transplant (BMT), but the precise roles of individual selectins in this process have never been defined. BMT of lethally irradiated mice lacking both endothelial selectins (E/P KO) with limiting numbers of wild type BM cells rescued significantly fewer E/P KO than WT recipients, but higher numbers of transplanted WT cells rescued E/P KOs in a dose-dependent fashion. Short-term homing assays confirmed a substantial defect in HSPC homing to BM in E/P KO mice. In contrast, BMT of E-selectin null or P-selectin null mice at limiting cell number uniformly rescued greater than 95% of the transplanted animals. Consistent with these functional results, flow cytometric analysis revealed both E-selectin ligands and P-selectin ligands on distinct subsets of HSPC. These results demonstrate overlapping functions for the endothelial selectins in HSPC homing to BM in the setting of BMT, and define a novel aspect of HSPC heterogeneity linked to selectin ligand expression.

AB Introduction: Alzheimer's disease (AD) is a common neurodegenerative disorder affecting an increasing number of people worldwide as the population ages. Currently, there are no drugs available that could prevent AD pathogenesis or slow down its progression. Increasing evidence links ubiquilin-1, an ubiquitin-like protein, into the pathogenic mechanisms of AD and other neurodegenerative diseases. Ubiquilin-1 has been shown to play a key role in the regulation of the levels, subcellular targeting, aggregation and degradation of various neurodegenerative disease-associated proteins. These include the amyloid precursor protein and presenilins that are intimately involved in the mechanisms of AD.
Areas covered: Here, the properties and diverse functions of ubiquilin-1 protein in the context of the pathogenesis of AD and other neurodegenerative disorders are discussed. This review recapitulates the available knowledge on the involvement of ubiquilin-1 in the genetic and molecular mechanisms in AD. Furthermore, the association of ubiquilin-1 with specific proteins and mechanisms involved in the pathogenesis of neurodegenerative diseases is described and the known ubiquilin-1-interacting proteins summarized.
Expert opinion: The variety of ubiquilin-1-interacting proteins and its central role in the regulation of protein levels and degradation provides a number of novel candidates and approaches for future research and drug discovery.

AB The distributions of coalescence times and ancestral lineage numbers play an essential role in coalescent modeling and ancestral inference. Both exact distributions of coalescence times and ancestral lineage numbers are expressed as the sum of alternating series, and the terms in the series become numerically intractable for large samples. More computationally attractive are their asymptotic distributions, which were derived in Griffiths (1984) for populations with constant size. In this article, we derive the asymptotic distributions of coalescence times and ancestral lineage numbers for populations with temporally varying size. For a sample of size n, denote by T-m the mth coalescent time, when m + 1 lineages coalesce into m lineages, and A(n)(t) the number of ancestral lineages at time t back from the current generation. Similar to the results in Griffiths (1984), the number of ancestral lineages, A(n)(t), and the coalescence times, T-m, are asymptotically normal, with the mean and variance of these distributions depending on the population size function, N(t). At the very early stage of the coalescent, when t -> 0, the number of coalesced lineages n - A(n)(t) follows a Poisson distribution, and as m -> n, n(n - 1)T-m/2N(0) follows a gamma distribution. We demonstrate the accuracy of the asymptotic approximations by comparing to both exact distributions and coalescent simulations. Several applications of the theoretical results are also shown: deriving statistics related to the properties of gene genealogies, such as the time to the most recent common ancestor (TMRCA) and the total branch length (TBL) of the genealogy, and deriving the allele frequency spectrum for large genealogies. With the advent of genomic-level sequencing data for large samples, the asymptotic distributions are expected to have wide applications in theoretical and methodological development for population genetic inference.

AB BACKGROUND The role of atrioventricular optimization (AVO) for cardiac resynchronization therapy (CRT) is controversial. Identifying subgroups that benefit from optimization is important to improve CRT outcomes. Pacing at sites of late electrical activation, as assessed by the QLV interval, improves remodeling with CRT.
OBJECTIVE To evaluate whether pacing at sites of long left ventricular (LV) electrical delay increases the effectiveness of AVO.
METHODS This substudy of the SMART-AV trial included 280 subjects who were randomized to either an electrogram-based AVO (SmartDelay) or nominal atrioventricular delay (120 ms). The QLV interval was defined as the time from the onset of QRS to the LV electrogram peak. CRT response was defined prospectively as a >15% reduction in left ventricular end systolic volume from implant to 6 months.
RESULTS The cohort was 68% men, with a mean age of 66 +/- 11 years and LV ejection fraction of 28% +/- 8%. Longer QLV durations were significantly associated with CRT response (P < .01) for the entire cohort. Moreover, the benefit of AVO increased as QLV prolonged. At the longest QLV quartile, there was more than a 6-fold increase in the likelihood of a remodeling response compared with nominal atrioventricular delays.
CONCLUSIONS Baseline electrical dyssynchrony, as measured by the QLV interval, predicted CRT response. At long QLV intervals, AVO can increase the likelihood of structural response to CRT. AVO and QLV optimized that LV lead location may work synergistically to maximize CRT response.

AB BACKGROUND Both schizophrenia and epilepsy have been linked to increased risk of sudden cardiac death (SCD). We hypothesized that DNA variants within genes previously associated with schizophrenia and epilepsy may contribute to an increased risk of SCD.
OBJECTIVE To investigate the contribution to SCD susceptibility of DNA variants previously implicated in schizophrenia and epilepsy.
METHODS From the ongoing Oregon Sudden Unexpected Death Study, comparisons were performed among 340 SCD cases presenting with ventricular fibrillation and 342 controls. We tested for the association between 17 single-nucleotide polymorphisms (SNPs) mapped to 14 loci previously implicated in schizophrenia and epilepsy by using logistic regression and assuming additive, dominant, and recessive genetic models.
RESULTS The minor allele of the nonsynonymous SNP rs10503929 within the neuregulin 1 gene was associated with SCD under all 3 investigated models, with the strongest association for the recessive genetic model (recessive P = 4.01 x 10(-5), odds ratio [OR] 4.04; additive P = 2.84 x 10(-7), OR 1.9; and dominant P = 9.01 x 10(-6), OR 2.06). To validate our findings, we further explored the association of this variant in the Harvard Cohort SCD study. The SNP rs10503929 was associated with an increased risk of SCD under the recessive genetic model (P = .0005, OR 2.7). This missense variation causes a methionine to threonine change and functional effects are currently unknown.
CONCLUSIONS The observed association between a schizophrenia-related neuregulin 1 gene variant and SCD may represent the first evidence of coexisting genetic susceptibility between 2 conditions that have an established clinical overlap. Further investigation is warranted to explore the molecular mechanisms of this variant in the pathogenesis of SCD.

AB We have recently proposed a correlated model to provide a Gaussian mixture representation of the cardiovascular signals, with promising results in identifying rhythm disturbances. The approach provides a transformation of the data into a set of integrable Gaussians distributed over time. Looking into the model from a new joint modeling perspective, it is capable of assembling a filtered estimation, and can be used to derive temporal information of the waveforms. In this paper, we present a step-by-step derivation of the joint model putting correlation assumptions together to conclude a minimal joint description for a pair of ECG-ABP signals. We then probe novel applications of this model, including Kalman filter based denoising and fiducial point detection. In particular, we use the joint model for denoising and employ the de-noised signals for pulse transit time (PTT) estimation. We analyzed more than 70 h of data from 76 patients from the MIMIC database to illustrate the accuracy of the algorithm. We have found that this method can be effectively used for robust joint ECG-ABP noise suppression, with mean signal-to-noise ratio (SNR) improvement up to 23.2 (12.0) dB and weighted diagnostic distortion measures as low as 2.1 (3.3)% for artificial (real) noises, respectively. In addition, we have estimated the error distributions for QT interval, systolic and diastolic blood pressure before and after filtering to demonstrate the maximal preservation of morphological features (Delta QT: mean +/- std = 2.2 +/- 6.1 ms; Delta SBP: mean +/- std = 2.3 +/- 1.9 mmHg; Delta DBP: mean +/- std = 1.9 +/- 1.4 mmHg). Finally, we have been able to present a systematic approach for robust PTT estimation (r = 0.98, p < 0.001, mean +/- std of error = -0.26 +/- 2.93 ms). These findings may have important implications for reliable monitoring and estimation of clinically important features in clinical settings. In conclusion, the proposed framework opens the door to the possibility of deploying a hybrid system that integrates these algorithmic approaches for index estimation and filtering scenarios with high output SNRs and low distortion.

AB The amount of calibration data needed to produce images of adequate quality can prevent auto-calibrating parallel imaging reconstruction methods like generalized autocalibrating partially parallel acquisitions (GRAPPA) from achieving a high total acceleration factor. To improve the quality of calibration when the number of auto-calibration signal (ACS) lines is restricted, we propose a sparsity-promoting regularized calibration method that finds a GRAPPA kernel consistent with the ACS fit equations that yields jointly sparse reconstructed coil channel images. Several experiments evaluate the performance of the proposed method relative to unregularized and existing regularized calibration methods for both low-quality and underdetermined fits from the ACS lines. These experiments demonstrate that the proposed method, like other regularization methods, is capable of mitigating noise amplification, and in addition, the proposed method is particularly effective at minimizing coherent aliasing artifacts caused by poor kernel calibration in real data. Using the proposed method, we can increase the total achievable acceleration while reducing degradation of the reconstructed image better than existing regularized calibration methods.

AB Objective: To determine whether use of uterine balloon tamponade (UBT) for management of uncontrolled postpartum hemorrhage (PPH) by community-based providers in a resource-limited setting could be feasible, effective, and safe. Methods: In rural South Sudan, community providers were trained and equipped with a simple UBT device consisting of a catheter, condom, and syringe. Snowball sampling identified cases of UBT use since training. Semi-structured interviews were conducted among community providers, referral facility providers, patients, and patient family members. Interview transcripts were analyzed using qualitative methods. Results: Thirteen cases were identified and 24 interviews related to community-based UBT use were conducted. Qualitative analysis revealed several major themes. Community providers applied UBT in appropriate clinical situations. UBT was effective for controlling PPH, even among severely ill patients. Referral was difficult and lengthy owing to the austere setting, but simple UBT appeared to mitigate these challenges. Communities had some initial fears, yet ultimately embraced UBT. Equipment and supplies were largely maintained. There was universal satisfaction with UBT among patients, family members, and providers. One death occurred among the 13 cases, although it was probably not attributable to PPH. Conclusion: Training and UBT device provision are simple, affordable, and effective for managing uncontrolled PPH in a resource-limited setting.

AB Objective: To describe a modified rolled superior pharyngeal flap for treatment of velopharyngeal insufficiency (VPI) in children.
Methods: Prospective case series at a tertiary care multidisciplinary aerodigestive center. Four children, aged 5-12 years, with VPI refractory to speech therapy resulting after cleft palate (bilateral, submucous, or soft palate only) repair, failed traditional superior pharyngeal flap, fine motor incoordination, or adenoidectomy were studied. All 4 children underwent surgery with a modified superior pharyngeal flap, where aspects of the most commonly employed pharyngeal flap designs were combined to achieve the benefits of each technique and to allow for mucosal covering on either side of the flap, improved control of the lateral port size due to the horizontal-to-horizontal inset technique, and the ability to avoid a vertical or horizontal split in a previously repaired cleft palate.
Results: All 4 patients demonstrated resolution of their VPI as measured by subjective and/or objective criteria. Every patient required additional speech therapy postoperatively.
Conclusions: Our modified superior pharyngeal flap technique may be a good option in patients with small velopharyngeal gaps undergoing revision velopharyngeal surgery. A larger, longitudinal study would better address the overall outcomes of this technique. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

AB OBJECTIVES The aim of this study was to evaluate whether computed tomography (CT) attenuation, as a measure of fat quality, is associated with cardiometabolic risk factors above and beyond fat quantity.
BACKGROUND Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) are pathogenic fat depots associated with cardiometabolic risk. Adipose tissue attenuation in CT images is variable, similar to adipose tissue volume. However, whether the quality of abdominal fat attenuation is associated with cardiometabolic risk independent of the quantity is uncertain.
METHODS Participants were drawn from the Framingham Heart Study CT substudy. The VAT and SAT volumes were acquired by semiquantitative assessment. Fat quality was measured by CT attenuation and recorded as mean Hounsfield unit (HU) within each fat depot. Sex-specific linear and logistic multivariable regression models were used to assess the association between standard deviation (SD) decrease in HU and each risk factor.
RESULTS Lower CT attenuation of VAT and SAT was correlated with higher body mass index levels in both sexes. Risk factors were generally more adverse with decreasing HU values. For example, in women, per 1 SD decrease in VAT HU, the odds ratio (OR) was increased for hypertension (OR: 1.80), impaired fasting glucose (OR: 2.10), metabolic syndrome (OR: 3.65), and insulin resistance (OR: 3.36; all p < 0.0001). In models that further adjusted for VAT volume, impaired fasting glucose, metabolic syndrome, and insulin resistance remained significant. Trends were similar but less pronounced for SAT and for men. There was evidence of an interaction between HU and fat volume among both women and men.
CONCLUSIONS Lower CT attenuation of VAT and SAT is associated with adverse cardiometabolic risk above and beyond total adipose tissue volume. Qualitative indices of abdominal fat depots may provide insight regarding cardiometabolic risk independent of fat quantity. (C) 2013 by the American College of Cardiology Foundation

TI Co-occurring posttraumatic stress and depression symptoms after sexual
assault: A latent profile analysis

AB Background: Symptoms of posttraumatic stress disorder (PTSD) and depression frequently co-occur, but their distinctiveness following trauma remains unclear. We examined patterns of PTSD and depression symptoms after sexual assault to evaluate the extent to which assault survivors primarily reported symptoms of both disorders or whether there were meaningfully distinct subgroups with discordant PTSD and depression symptoms.
Methods: Latent profile analysis was used to examine self-reported PTSD and depression symptoms among 119 female sexual assault survivors at 1-, 2-, 3-, and 4-months post-assault.
Results: At all time points, a 4-class solution fit the data best, revealing four subgroups with low, low-moderate, high-moderate, and severe levels of both PTSD and depression symptoms. Within each subgroup, PTSD symptom severity co-occurred with comparable depression symptom severity. At no time point were there reliable subgroups with discordant PTSD and depression symptom seventies. Emotional numbing, hyperarousal, and overall PTSD symptom severity reliably distinguished each class from the others. Class membership at 1-month post-assault predicted subsequent class membership and functional impairment.
Limitations: Additional research is needed to evaluate predictors of class membership, temporal stability of classes, and generalizability to other trauma populations.
Conclusions: Co-occurring and comparably severe PTSD and depression symptoms are pervasive among female sexual assault survivors. The absence of a distinct subset of individuals with only PTSD or depression symptoms suggests that PTSD and depression may be manifestations of a general posttraumatic stress response rather than distinct disorders after trauma. Integrated treatments targeting both PTSD and depression symptoms may therefore prove more efficient and effective. Published by Elsevier B.V.

AB Background: Since little is known as to whether sex differences affect the clinical presentation of pediatric BP-I disorder, it is an area of high clinical, scientific and public health relevance.
Methods: Subjects are 239 BP-I probands (65 female probands, 174 male probands) and their 726 first-degree relatives, and 136 non-bipolar, non-ADHD control probands (37 female probands, 99 male probands) and their 411 first-degree relatives matched for age and sex. We modeled the psychiatric and cognitive outcomes as a function of BP-I status, sex, and the BP-I status-gender interaction.
Results: BP-I disorder was equally familial in both sexes. With the exception of duration of mania (shorter in females) and number of depressive episodes (more in females), there were no other meaningful differences between the sexes in clinical correlates of BP-I disorder. With the exception of a significant sex effect for panic disorder and a trend for substance use disorders (p=0.05) with female probands being at a higher risk than male probands, patterns of comorbidity were similar between the sexes. Despite the similarities, boys with BP-I disorder received more intensive and costly academic services than girls with the same disorder.
Limitations: Since we studied children referred to a family study of bipolar disorder, our findings may not generalize to clinic settings.
Conclusions: We found more similarities than differences between the sexes in the personal and familial correlates of BP-I disorder. Clinicians should consider bipolar disorder in the differential diagnosis of both boys and girls afflicted with symptoms suggestive of this disorder. (C) 2013 Elsevier B.V. All rights reserved.

AB Background: We sought to determine the prevalence and correlates of suicidal ideation (SI) among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans following the Department of Veterans Affairs' (VA) 2007 implementation of required brief SI assessments for veterans who screen positive for depression and post-traumatic stress disorder.
Methods: We retrospectively identified OEF/OIF veterans screened for depression using the Patient Health Questionnaire (PHQ-2) between April 2008 and September 2009 at three geographically-distinct VA Medical Centers' primary care or mental health clinics. Veteran responses to a two-item risk assessment tool (VA Pocket Card) or PHQ-9 9th item, administered following a positive depression screen (PHQ-2 > 3), were determined using manual chart review. Generalized estimating equations were used to calculate adjusted odds ratios for demographic and clinical correlates of positive SI assessments.
Results: Of 1340 OEF/OIF veterans with positive depression screens, 32.4% reported SI. In multivariate models, odds of SI were lower for non-Hispanic white veterans (AOR=0.68) and greater for those with PHQ-2 >= 5 (AOR=1.87), depression (AOR=1.45), bipolar disorder/schizophrenia (AOR=2.84), and 2 or >= 3 diagnoses (AORs=1.59 and 2.49, respectively).
Limitations: Study findings may not be generalizable to non-veteran patient populations and the study does not address the reliability and validity of tools employed for brief suicidal ideation assessment.
Conclusions: SI is common among OEF/OIF veterans who receive VA care, perhaps more so among non-white veterans. Targeting veterans with higher PHQ-2 scores for SI assessment should be considered to reduce patient and administrative burden. Published by Elsevier B.V.

TI A homozygous mucosa-associated lymphoid tissue 1 (MALT1) mutation in a
family with combined immunodeficiency
SO JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY
LA English
DT Article
DE MALT1; combined immunodeficiency (CID); NF-kappa B
ID T-CELL; ACTIVATION; IMMUNITY; DEFICIENCY; CARD11
AB Background: Combined immunodeficiency (CID) is characterized by severe recurrent infections with normal numbers of T and B lymphocytes but with deficient cellular and humoral immunity. Most cases are sporadic, but autosomal recessive inheritance has been described. In most cases, the cause of CID remains unknown.
Objective: We wanted to identify the genetic cause of CID in 2 siblings, the products of a first-cousin marriage, who experienced recurrent bacterial and candidal infections with bronchiectasis, growth delay, and early death.
Methods: We performed immunologic, genetic, and biochemical studies in the 2 siblings, their family members, and healthy controls. Reconstitution studies were performed with T cells from mucosa-associated lymphoid tissue lymphoma-translocation gene 1-deficient (Malt1(-/-)) mice.
Results: The numbers of circulating T and B lymphocytes were normal, but T-cell proliferation to antigens and antibody responses to vaccination were severely impaired in both patients. Whole genome sequencing of 1 patient and her parents, followed by DNA sequencing of family members and healthy controls, showed the presence in both patients of a homozygous missense mutation in MALT1 that resulted in loss of protein expression. Analysis of T cells that were available on one of the patients showed severely impaired I kappa B alpha degradation and IL-2 production after activation, 2 events that depend on MALT1. In contrast to wild-type human MALT1, the patients' MALT1 mutant failed to correct defective nuclear factor-kappa B activation and IL-2 production in MALT1-deficient mouse T cells.
Conclusions: An autosomal recessive form of CID is associated with homozygous mutations in MALT1. If future patients are found to be similarly affected, they should be considered as candidates for allogeneic hematopoietic cell transplantation.

AB To determine how the obstructive sleep apnea (OSA) patient's pathophysiological traits predict the success of the treatment aimed at stabilization or increase in respiratory motor outputs, we studied 26 newly diagnosed OSA patients [apnea-hypopnea index (AHI) 42 +/- 5 events/h with 92% of apneas obstructive] who were treated with O-2 supplementation, an isocapnic rebreathing system in which CO2 was added only during hyperpnea to prevent transient hypocapnia, and a continuous rebreathing system. We also measured each patient's controller gain below eupnea [change in minute volume/change in end-tidal PCO2 (Delta(V)over dotE/Delta PETCO2)], CO2 reserve (eupnea-apnea threshold PETCO2), and plant gain (Delta PETCO2 /Delta(V)over dotE), as well as passive upper airway closing pressure (Pcrit). With isocapnic rebreathing, 14/26 reduced their AHI to 31 +/- 6% of control (P < 0.01) (responder); 12/26 did not show significant change (nonresponder). The responders vs. nonresponders had a greater controller gain (6.5 +/- 1.7 vs. 2.1 +/- 0.2 l.min(-1).mmHg(-1), P < 0.01) and a smaller CO2 reserve (1.9 +/- 0.3 vs. 4.3 +/- 0.4 mmHg, P < 0.01) with no differences in Pcrit (-0.1 +/- 1.2 vs. 0.2 +/- 0.9 cmH(2)O, P > 0.05). Hypercapnic rebreathing (+4.2 +/- 1 mmHg PETCO2) reduced AHI to 15 +/- 4% of control (P < 0.001) in 17/21 subjects with a wide range of CO2 reserve. Hyperoxia (SaO(2) similar to 95-98%) reduced AHI to 36 +/- 11% of control in 7/19 OSA patients tested. We concluded that stabilizing central respiratory motor output via prevention of transient hypocapnia prevents most OSA in selected patients with a high chemosensitivity and a collapsible upper airway, whereas increasing respiratory motor output via moderate hypercapnia eliminates OSA in most patients with a wider range of chemosensitivity and CO2 reserve. Reducing chemosensitivity via hyperoxia had a limited and unpredictable effect on OSA.

AB Stent deployments with geographical miss (GM) are associated with increased risk of target-vessel revascularization and periprocedural myocardial infarction. The aim of the current study was to investigate the underlying biomechanical mechanisms for adverse events with GM. The hypothesis is that stent deployment with GM [ longitudinal GM, or LGM (i.e., stent not centered on the lesion); or radial GM, RGM (i.e., stent oversizing)] results in unfavorable fluid wall shear stress (WSS), WSS gradient (WSSG), oscillatory shear index (OSI), and intramural circumferential wall stress (CWS). Three-dimensional computational models of stents and plaque were created using a computer-assisted design package. The models were then solved with validated finite element and computational fluid dynamic packages. The dynamic process of large deformation stent deployment was modeled to expand the stent to the desired vessel size. Stent deployed with GM resulted in a 45% increase in vessel CWS compared with stents that were centered and fully covered the lesion. A 20% oversized stent resulted in 72% higher CWS than a correct sized stent. The linkages between the struts had much higher stress than the main struts (i.e., 180 MPa vs. 80 MPa). Additionally, LGM and RGM reduced endothelial WSS and increased WSSG and OSI. The simulations suggest that both LGM and RGM adversely reduce WSS but increase WSSG, OSI, and CWS. These findings highlight the potential mechanical mechanism of the higher adverse events and underscore the importance of stent positioning and sizing for improved clinical outcome.

AB Individualized stroke treatment decisions can be improved by accurate identification of the extent of salvageable tissue. Magnetic resonance imaging (MRI)-based approaches, including measurement of a 'perfusion-diffusion mismatch' and calculation of infarction probability, allow assessment of tissue-at-risk; however, the ability to explicitly depict potentially salvageable tissue remains uncertain. In this study, five predictive algorithms (generalized linear model (GLM), generalized additive model, support vector machine, adaptive boosting, and random forest) were tested in their potency to depict acute cerebral ischemic tissue that can recover after reperfusion. Acute T-2-, diffusion-, and perfusion-weighted MRI, and follow-up T-2 maps were collected from rats subjected to right-sided middle cerebral artery occlusion without subsequent reperfusion, for training of algorithms (Group I), and with spontaneous (Group II) or thrombolysis-induced reperfusion (Group III), to determine infarction probability-based viability thresholds and prediction accuracies. The infarction probability difference between irreversible-i.e., infarcted after reperfusion-and salvageable tissue injury-i.e., noninfarcted after reperfusion-was largest for GLM (20 +/- 7%) with highest accuracy of risk-based identification of acutely ischemic tissue that could recover on subsequent reperfusion (Dice's similarity index = 0.79 +/- 0.14). Our study shows that assessment of the heterogeneity of infarction probability with MRI-based algorithms enables estimation of the extent of potentially salvageable tissue after acute ischemic stroke.

AB The mechanisms by which deregulated nuclear factor erythroid-2-related factor 2 (NRF2) and kelch-like ECH-associated protein 1 (KEAP1) signaling promote cellular proliferation and tumorigenesis are poorly understood. Using an integrated genomics and C-13-based targeted tracer fate association (TTFA) study, we found that NRF2 regulates miR-1 and miR-206 to direct carbon flux toward the pentose phosphate pathway (PPP) and the tricarboxylic acid (TCA) cycle, reprogramming glucose metabolism. Sustained activation of NRF2 signaling in cancer cells attenuated miR-1 and miR-206 expression, leading to enhanced expression of PPP genes. Conversely, overexpression of miR-1 and miR-206 decreased the expression of metabolic genes and dramatically impaired NADPH production, ribose synthesis, and in vivo tumor growth in mice. Loss of NRF2 decreased the expression of the redox-sensitive histone deacetylase, HDAC4, resulting in increased expression of miR-1 and miR-206, and not only inhibiting PPP expression and activity but functioning as a regulatory feedback loop that repressed HDAC4 expression. In primary tumor samples, the expression of miR-1 and miR-206 was inversely correlated with PPP gene expression, and increased expression of NRF2-dependent genes was associated with poor prognosis. Our results demonstrate that microRNA-dependent (miRNA-dependent) regulation of the PPP via NRF2 and HDAC4 represents a novel link between miRNA regulation, glucose metabolism, and ROS homeostasis in cancer cells.

AB Background: To evaluate safety and efficacy of inhaled mannitol treatment in subgroups of a large global CF population.
Methods: Data were pooled from two multicentre, double-blind, randomised, controlled, parallel group phase III studies in which 600 patients inhaled either mannitol (400 mg) or control (mannitol 50 mg) twice a day for 26 weeks.
Results: Both the mean absolute change in FEV1 (mL) and relative change in FEV1 by % predicted from baseline for mannitol (400 mg) versus control were statistically significant (73.42 mL, 3.56%, both p<0.001). Increases in FEV1 were observed irrespective of rhDNase use. Significant improvements in FEV1 occurred in adults but not children (6-11) or adolescents (aged 12-17). Pulmonary exacerbation incidence was reduced by 29% (p=0.039) in the mannitol (400 mg) group.
Conclusions: Sustained six-month improvements in lung function and decreased pulmonary exacerbation incidence indicate that inhaled mannitol is an important additional drug in the treatment of CF. (c) 2012 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.

AB Purpose To assess whether there was a difference in score between paper and telephone administration of disability and psychological questionnaires relevant to patients with an upper extremity illness.
Methods The short version of the Disabilities of the Arm, Shoulder, and Hand score, the 5-question version of the Short Health Anxiety Inventory, the 4-question version of the Pain Catastrophizing Scale, the Patient Health Questionnaire-2, and an ordinal pain scale were completed by 135 patients both in the office and the next day over the phone. We compared scores with repeated measures analysis of variance and Pearson correlation. We used intraclass correlation coefficients to test the level of agreement.
Results There were small but significant differences between paper and phone administration of the short version of the Disabilities of the Arm, Shoulder, and Hand scores and pain scores, but not the Patient Health Questionnaire-2, Short Health Anxiety Inventory-5, and Pain Catastrophizing Scale-4. There was a large Pearson correlation and excellent intraclass correlation coefficient agreement, as well.
Conclusions Shorter questionnaires can be used to assess disability and psychological factors by phone. Phone administration of measures of disability and psychological factors can replace paper administration in studies that do not require in-person examination.

AB Purpose: To explore the use of approximate entropy (ApEn) as an index of the complexity and the synchronicity of resting state blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) in normal aging and cognitive decline associated with familial Alzheimer's disease (fAD).
Materials and Methods: Resting state BOLD fMRI data were acquired at 3T from two independent cohorts of subjects consisting of healthy young (age 23 +/- 2 years, n = 8) and aged volunteers (age 66 +/- 3 years, n = 8), as well as 22 fAD associated subjects (14 mutation carriers, age 41.2 +/- 15.8 years; and eight nonmutation carrying family members, age 28.8 +/- 5.9 years). Mean ApEn values were compared between the two age groups and correlated with cognitive performance in the fAD group. Cross-ApEn (C-ApEn) was further calculated to assess the asynchrony between precuneus and the rest of the brain.
Results: Complexity of brain activity measured by mean ApEn in gray and white matter decreased with normal aging. In the fAD group, cognitive impairment was associated with decreased mean ApEn in gray matter as well as decreased regional ApEn in right precuneus, right lateral parietal regions, left precentral gyrus, and right paracentral gyrus. A pattern of asynchrony between BOLD fMRI series emerged from C-ApEn analysis, with significant regional anti-correlation with cross-correlation coefficient of functional connectivity analysis.
Conclusion: ApEn and C-ApEn may be useful for assessing the complexity and synchronicity of brain activity in normal aging and cognitive decline associated with neuro-degenerative diseases.

AB Background: The quality of end-of-life (EOL) care at Veterans Affairs Medical Centers (VAMC) has improved. To date, however, the quality and outcomes of end-of-life care delivered to women veterans have not been examined.
Objective: The goal of this study was to evaluate gender differences in the quality of EOL care received by patients in VAMCs nationwide.
Design: The study was conducted via retrospective medical chart review and telephone survey with next of kin of recently deceased inpatients.
Setting/subjects: The chart review included records for all patients who died in acute and long-term care units in 145 VAMCs nationwide (n = 36,618). For the survey, the documented next of kin were invited to respond on behalf of the deceased veteran; a total of 25,638 next of kin completed the survey.
Measurements: Chart review measures included five indicators of optimal end-of-life care. Bereaved family survey items included one global and nine specific items (e. g., bereavement care, pain management) describing care in the last month of life.
Results: Receipt of optimal end-of-life care did not differ significantly between women and men with respect to frequency of discussion of treatment goals with a family member, receipt of palliative consult, bereavement contact, and chaplain contact with a family member. Family members of women were more likely than those of men to report that the overall care provided to the veteran had been "excellent" (adjusted proportions: 63% versus 56%; odds ratio (OR) = 1.33; 95% confidence interval (CI) 1.10-1.61; p = 0.003).
Conclusions: In this nationwide study of all inpatient deaths in VAMCs, women received comparable and on some metrics better quality EOL care than that received by male patients.

TI Propranolol's effects on the consolidation and reconsolidation of
long-term emotional memory in healthy participants: a meta-analysis

AB Background: Considering the pivotal role of negative emotional experiences in the development and persistence of mental disorders, interfering with the consolidation/reconsolidation of such experiences would open the door to a novel treatment approach in psychiatry. We conducted a meta-analysis on the experimental evidence regarding the capacity of the beta-blocker propranolol to block the consolidation/reconsolidation of emotional memories in healthy adults. Methods: Selected studies consisted of randomized, double-blind experiments assessing long-term memory for emotional material in healthy adults and involved at least 1 propranolol and 1 placebo condition. We searched PsycInfo, PubMed, Web of Science, Cochrane Central, PILOTS, Google Scholar and clinicaltrials.org for eligible studies from the period 1995-2012. Ten consolidation (n = 259) and 8 reconsolidation (n = 308) experiments met the inclusion criteria. We calculated effect sizes (Hedges g) using a random effects model. Results: Compared with placebo, propranolol given before memory consolidation reduced subsequent recall for negatively valenced stories, pictures and word lists (Hedges g = 0.44, 95% confidence interval [CI] 0.14-0.74). Propranolol before reconsolidation also reduced subsequent recall for negatively valenced emotional words and the expression of cue-elicited fear responses (Hedges g = 0.56, 95% CI 0.13-1.00). Limitations: Limitations include the moderate number of studies examining the influence of propranolol on emotional memory consolidation and reconsolidation in healthy adults and the fact that most samples consisted entirely of young adults, which may limit the ecological validity of results. Conclusion: Propranolol shows promise in reducing subsequent memory for new or recalled emotional material in healthy adults. However, future studies will need to investigate whether more powerful idiosyncratic emotional memories can also be weakened and whether this weakening can bring about long-lasting symptomatic relief in clinical populations, such as patients with posttraumatic stress or other event-related disorders.

AB Context: Spinal cord injury (SCI) results in a loss of function and sensation below the level of the lesion. Neuroprosthetic technology has been developed to help restore motor and autonomic functions as well as to provide sensory feedback.
Findings: This paper provides an overview of neuroprosthetic technology that aims to address the priorities for functional restoration as defined by individuals with SCI. We describe neuroprostheses that are in various stages of preclinical development, clinical testing, and commercialization including functional electrical stimulators, epidural and intraspinal microstimulation, bladder neuroprosthesis, and cortical stimulation for restoring sensation. We also discuss neural recording technologies that may provide command or feedback signals for neuroprosthetic devices.
Conclusion/clinical relevance: Neuroprostheses have begun to address the priorities of individuals with SCI, although there remains room for improvement. In addition to continued technological improvements, closing the loop between the technology and the user may help provide intuitive device control with high levels of performance.

TI Vertical ground reaction force-based analysis of powered

ID SPINAL-CORD-INJURY; RECIPROCATING GAIT ORTHOSIS
AB Objective: To use vertical ground reaction force (vGRF) to show the magnitude and pattern of mechanical loading in persons with spinal cord injury (SCI) during powered exoskeleton-assisted walking.
Research design: A cross-sectional study was performed to analyze vGRF during powered exoskeleton-assisted walking (ReWalk (TM): Argo Medical Technologies, Inc, Marlborough, MA, USA) compared with vGRF of able-bodied gait.
Setting: Veterans Affairs Medical Center.
Participants: Six persons with thoracic motor-complete SCI (T1-T11 AIS A/B) and three age-, height-, weight- and gender-matched able-bodied volunteers participated.
Interventions: SCI participants were trained to ambulate over ground using a ReWalk (TM). vGRF was recorded using the F-Scan (TM) system (TekScan, Boston, MA, USA).
Outcome measures: Peak stance average (PSA) was computed from vGRF and normalized across all participants by percent body weight. Peak vGRF was determined for heel strike, mid-stance, and toe-off. Relative linear impulse and harmonic analysis provided quantitative support for analysis of powered exoskeletal gait.
Results: Participants with motor-complete SCI, ambulating independently with a ReWalk (TM), demonstrated mechanical loading magnitudes and patterns similar to able-bodied gait. Harmonic analysis of PSA profile by Fourier transform contrasted frequency of stance phase gait components between able-bodied and powered exoskeleton-assisted walking.
Conclusion: Powered exoskeleton-assisted walking in persons with motor-complete SCI generated vGRF similar in magnitude and pattern to that of able-bodied walking. This suggests the potential for powered exoskeleton-assisted walking to provide a mechanism for mechanical loading to the lower extremities. vGRF profile can be used to examine both magnitude of loading and gait mechanics of powered exoskeleton-assisted walking among participants of different weight, gait speed, and level of assist.

AB Objective: To develop a virtual reality (VR)-based simulator that can assist clinicians in performing standardized wheelchair driving assessments.
Design: A completely within-subjects repeated measures design.
Methods: Participants drove their wheelchairs along a virtual driving circuit modeled after the Power Mobility Road Test (PMRT) and in a hallway with decreasing width. The virtual simulator was displayed on computer screen and VR screens and participants interacted with it using a set of instrumented rollers and a wheelchair joystick. Driving performances of participants were estimated and compared using quantitative metrics from the simulator. Qualitative ratings from two experienced clinicians were used to estimate intra- and inter-rater reliability.
Results: Ten regular wheelchair users (seven men, three women; mean age +/- SD, 39.5 +/- 15.39 years) participated. The virtual PMRT scores from the two clinicians show high inter-rater reliability (78-90%) and high intra-rater reliability (71-90%) for all test conditions. More research is required to explore user preferences and effectiveness of the two control methods (rollers and mathematical model) and the display screens.
Conclusions: The virtual driving simulator seems to be a promising tool for wheelchair driving assessment that clinicians can use to supplement their real-world evaluations.

AB Objective: The purpose of this study was to evaluate whole-body vibration (WBV) exposure to wheelchair (WC) users in their communities and to determine the effect of WC frame type (folding, rigid, and suspension) in reducing WBV transmitted to the person.
Design: An observational case-control study of the WBV exposure levels among WC users.
Participants: Thirty-seven WC users, with no pressure sores, 18 years old or older and able to perform independent transfers.
Main outcome measures: WC users were monitored for 2 weeks to collect WBV exposure, as well as activity levels, by using custom vibration and activity data-loggers. Vibration levels were evaluated using ISO 2631-1 methods.
Results: All WC users who participated in this study were continuously exposed to WBV levels at the seat that were within and above the health caution zone specified by ISO 2631-1 during their day-to-day activities (0.83 +/- 0.17 m/second(2), weighted root-mean-squared acceleration, for 13.07 +/- 3.85 hours duration of exposure). WCs with suspension did not attenuate vibration transmitted to WC users (V = 0.180, F(8, 56) = 0.692, P = 0.697).
Conclusions: WBV exposure to WC users exceeds international standards. Suspension systems need to be improved to reduce vibrations transmitted to the users.

AB Vitamin D promotes the differentiation of prostate cancer cells, raising the possibility that vitamin D deficiency over time may contribute to the progression from subclinical prostate cancer to clinical disease. Since low-risk prostate cancers are monitored over time in an effort to determine which progress into clinically important, more aggressive cancers, they provide an excellent model in which to study, over an extended period of time, the effects of enhancing vitamin D status and related changes in tumor progression. This is particularly relevant to African-American men, who exhibit a high prevalence of vitamin D deficiency as well as higher incidence of prostate cancer and higher mortality rates from prostate cancer than Caucasians. Our research team has recently completed an open-label clinical trial aimed at assessing the safety and potential efficacy of vitamin D-3 supplementation at 4000 international units (IU) per day for one year in subjects diagnosed with early stage, low-risk prostate cancer. The results of this clinical study suggest that supplementation with vitamin D-3 at 4000 IU per day may benefit patients with early stage, low-risk prostate cancer on active surveillance, because of the improved outcome (a decreased number of positive cores at repeat biopsy) in more than half of the subjects enrolled in the trial. We also observed that, after one year of supplementation, there was no difference in circulating levels of vitamin D between African-American and Caucasian subjects who completed the study. These clinical results also suggest that robust and sustained vitamin D-3 supplementation can reduce prostate cancer-related health disparities in African-American men and that these health disparities are at least in part the result of widespread hypovitaminosis D within the African-American population.

AB Vitamin D sufficiency is associated with protection against malignancy in a number of tissues clinically, and a strong body of evidence from animal and cell culture studies supports this protective role. Cancers in the skin differ, however, in that higher serum levels of 25OHD are associated with increased basal cell carcinomas (BCC), the most common form of epidermal malignancy. This result may be interpreted as indicating the role of UVR (spectrum 280-320) in producing vitamin D in the skin as well as causing those DNA mutations and proliferative changes that lead to epidermal malignancies. Recent animal studies have shown that mice lacking the vitamin D receptor (VDR) are predisposed to developing skin tumors either from chemical carcinogens such as 7,12-dimethylbenzanthracene (DMBA) or chronic UVR exposure. Such studies suggest that vitamin D production and subsequent signaling through the VDR in the skin may have evolved in part as a protective mechanism against UVR induced epidermal cancer formation. In this manuscript we provide evidence indicating that vitamin D signaling protects the skin from cancer formation by controlling keratinocyte proliferation and differentiation, facilitating DNA repair, and suppressing activation of the hedgehog (Hh) pathway following UVR exposure.

AB Objective: The objective of this secondary analysis was to explore differences in baseline clinical characteristics and opioid replacement therapy treatment outcomes by type (heroin, opioid analgesic [OA], or combined [heroin and OA]) and route (injector or non-injector) of opioid use. Method: A total of 1,269 participants (32.2% female) were randomized to receive one of two study medications (methadone or buprenorphine/naloxone [BUP]). Of these, 731 participants completed the 24-week active medication phase. Treatment outcomes were opioid use during the final 30 days of treatment (among treatment completers) and treatment attrition. Results: Non-opioid substance dependence diagnoses and injecting differentiated heroin and combined users from OA users. Non-opioid substance dependence diagnoses and greater heroin use differentiated injectors from non-injectors. Further, injectors were more likely to be using at end of treatment compared with non-injectors. OA users were more likely to complete treatment compared with heroin users and combined users. Non-injectors were more likely than injectors to complete treatment. There were no interactions between type of opioid used or injection status and treatment assignment (methadone or BUP) on either opioid use or treatment attrition. Conclusions: Findings indicate that substance use severity differentiates heroin users from OA users and injectors from non-injectors. Irrespective of medication, heroin use and injecting are associated with treatment attrition and opioid misuse during treatment. These results have particular clinical interest, as there is no evidence of superiority of BUP over methadone for treating OA users versus heroin users.

AB Objective: This study tested whether the addition of an enhanced continuing care (ECC) intervention that combined in-person and telephone sessions and began in the first week of treatment improved outcomes for cocaine-dependent patients entering an intensive outpatient program (IOP). Method: Participants (N = 152) were randomized to IOP treatment as usual (TAU) or IOP plus 12 months of ECC. ECC included cognitive-behavioral therapy elements to increase coping skills, as well as monetary incentives for attendance. It was provided by counselors situated at a separate clinical research facility who did not provide IOP. The primary outcomes measured were (a) cocaine urine toxicology and (b) good clinical outcome, as indicated by abstinence from all drugs and from heavy alcohol use. Secondary outcomes were frequency of abstinent days, cocaine use days, and heavy drinking days. Follow-ups were conducted at 3, 6, 9, and 12 months after baseline. Results: Patients in ECC completed a mean of 18 sessions. Contrary to the hypotheses, patients in TAU had better scores on both the cocaine urine toxicology and the good clinical outcome measures than those in ECC, as indicated by significant Group x Time interactions (cocaine urine toxicology, p=.0025; abstinence composite, p=.017). These results were not moderated by substance use before or early in treatment or by IOP attendance. Results with the secondary outcomes also did not favor ECC over TAU. Conclusions: Continuing care that is not well integrated with the primary treatment program may interfere in some way with the therapeutic process, particularly when it is implemented shortly after intake.

AB Objective: For low-lying rectal cancers, proximal diversion can reduce anastomotic leak after sphincter-preserving surgery; however, evidence suggests that such temporary diversions are often not reversed. We aimed to evaluate nonreversal and delayed stoma reversal in elderly patients undergoing low anterior resection (LAR).
Design: SEER-Medicare-linked analysis from 1991-2007.
Settings and participants: A total of 1179 primary stage I-III rectal cancer patients over age 66 who underwent LAR with synchronous diverting stoma.
Main outcome measures: (1) Stoma creation and reversal rates; (2) time to reversal; (3) characteristics associated with reversal and shorter time to reversal.
Results: Within 18 mo of LAR, 51% of patients (603/1179) underwent stoma reversal. Stoma reversal was associated with age <80 y (P < 0.0001), male sex (P = 0.018), fewer comorbidities (P = 0.017), higher income (quartile 4 versus 1; P = 0.002), early tumor stage (1 versus 3; P < 0.001), neoadjuvant radiation (P < 0.0001), rectal tumor location (versus rectosigmoid; P = 0.001), more recent diagnosis (P = 0.021), and shorter length of stay on LAR admission (P = 0.021). Median time to reversal was 126 d (interquartile range: 79-249). Longer time to reversal was associated with older age (P = 0.031), presence of comorbidities (P = 0.014), more advanced tumor stage (P = 0.007), positive lymph nodes (P = 0.009), receipt of adjuvant radiation therapy (P = 0.008), more recent diagnosis (P = 0.004), and longer length of stay on LAR admission (P < 0.0001).
Conclusions: Half of elderly rectal cancer patients who undergo LAR with temporary stoma have not undergone stoma reversal by 18 mo. Identifiable risk factors predict both nonreversal and longer time to reversal. These results help inform preoperative discussions and promote realistic expectations for elderly rectal cancer patients. (C) 2013 Elsevier Inc. All rights reserved.

AB Tissue engineering combines engineering principles with the biological sciences to create functional replacement tissues. The underlying principle of tissue engineering is that isolated cells combined with biomaterials can form new tissues and organs in vitro and in vivo. This review focuses on stomach tissue engineering, which is a promising approach to the treatment of gastric cancer, the fourth most common malignancy in the world and the second-leading cause of cancer mortality worldwide. Although gastrectomy is a reliable intervention to achieve complete removal of cancer lesions, the limited capacity for food intake after resection results in lower quality of life for patients. To address this issue, we have developed a tissue-engineered stomach to increase the capacity for food intake by creating a new food reservoir. We have transplanted this neo-stomach as a substitute for the original native stomach in a rat model and confirmed functional adaptation. Furthermore, we have demonstrated the feasibility of transplanting a tissue-engineered gastric wall patch in a rat model to alleviate the complications after resection of a large area of the gastric wall. Although progress has been achieved, significant challenges remain to bring this approach to clinical practice. Here, we summarize our work and present the state of the art in stomach tissue engineering. (C) 2013 Elsevier Inc. All rights reserved.

AB Purpose: National attention has focused on whether urology-radiation oncology practice integration, known as integrated prostate cancer centers, contributes to the use of intensity modulated radiation therapy, a common and expensive prostate cancer treatment.
Materials and Methods: We examined prostate cancer treatment patterns before and after conversion of a urology practice to an integrated prostate cancer center in July 2006. Using the SEER (Statistics, Epidemiology and End Results)-Medicare database, we identified patients 65 years old or older in 1 statewide registry diagnosed with nonmetastatic prostate cancer between 2004 and 2007. We classified patients into 3 groups, including 1-those seen by integrated prostate cancer center physicians (exposure group), 2-those living in the same hospital referral region who were not seen by integrated prostate cancer center physicians (hospital referral region control group) and 3-those living elsewhere in the state (state control group). We compared changes in treatment among the 3 groups, adjusting for patient, clinical and socioeconomic factors.
Results: Compared with the 8.1 ppt increase in adjusted intensity modulated radiation therapy use in the state control group, the use of this therapy increased 20.3 ppts (95% CI 13.4, 27.1) in the integrated prostate cancer center group and 19.2 ppts (95% CI 9.6, 28.9) in the hospital referral region control group. Androgen deprivation therapy, for which Medicare reimbursement decreased sharply, similarly decreased in integrated prostate cancer center and hospital referral region controls. Prostatectomy decreased significantly in the integrated prostate cancer center group.
Conclusions: Coincident with the conversion of a urology group practice to an integrated prostate cancer center, we observed an increase in intensity modulated radiation therapy and a decrease in androgen deprivation therapy in patients seen by integrated prostate cancer center physicians and those seen in the surrounding health care market that were not observed in the remainder of the state.

AB This phase II study to determine the safety and efficacy of denileukin diftitox (DD) and cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) enrolled patients with newly diagnosed peripheral T-cell lymphoma (PTCL). Forty-nine received DD 18 mu g/kg/day (days 1, 2) with CHOP (day 3) every 21 days for <= 6-8 cycles. Intent-to-treat (ITT) and safety populations comprised all patients. In the ITT population, the overall response rate was 65%, median duration of response was 30 months and median progression-free survival was 12 months. Median overall survival was not attained at the end of the study, and the overall survival rate was 63.3%. The two most frequent treatment-related adverse events (AEs) were fatigue and nausea. Most frequent AEs >= grade 3 within the hematologic system were lymphopenia (24.5%), neutropenia (20.4%) and leukopenia (18.4%). Three treatment-related deaths occurred. DD plus CHOP was well tolerated, and progression-free and overall survival improved versus historical comparison with CHOP alone. Confirmation in larger trials is warranted.

AB Introduction: Surgical resection currently is the best available treatment to enhance long-term survival after non-small cell lung cancer (NSCLC). With the anticipated growth in the number of NSCLC survivors diagnosed through computed tomography screening, health-related quality of life (HR-QOL) as an endpoint of treatment will become increasingly important. This article is a systematic review of the literature regarding HR-QOL in patients after surgical treatment.
Methods: Three computerized databases (PubMed, Medline, and CINHAL) were used to identify relevant articles. Inclusion criteria were: empirical studies English language, assessment of HR-QOL after surgical treatment for stage I, II, or III NSCLC, and publication prior to January 2012. Data were abstracted and content analyses were used to synthesize the findings.
Results: Nineteen out of 337 studies were reviewed. The majority of participants (67%) had stable or improved mental HR-QOL at 6-months after surgery. Compared with the general population, however, NSCLC survivors have poorer mental HR-QOL. Compared to pre-surgical status, participants had worse physical function at 6-months after surgery and had decreased physical function up to 2-years after surgery. Pain, fatigue, dyspnea and coughing were the most prevalent symptoms. Increased levels of dyspnea and fatigue persisted for at least 2-years after surgery. Continued smoking, presence of comorbidities, extensive surgical resection, and use of adjuvant therapy were associated with lower HR-QOL.
Conclusions: New interventions focused on smoking cessation, improving symptom control and physical function are needed to enhance HR-QOL after lung cancer surgery. Published by Elsevier Ireland Ltd.

AB Introduction: We conducted this analysis to determine whether survival of advanced NSCLC patients treated with platin-based chemotherapy doublets involving paclitaxel, docetaxel or gemcitabine was dependent on histological subtypes and treatment regimen.
Methods: We retrospectively analyzed data from El 594, a front-line phase III study in which advanced NSCLC patients were randomized to receive one of four regimens: cisplatin-paclitaxel, cisplatin-gemcitabine, cisplatin-docetaxel, and carboplatin-paclitaxel. Patients were classified into four histology groups: squamous cell (SCC), adeno- (AC), large cell (LCC) and others including not otherwise specified (0/NOS) carcinoma. Logrank test was performed to compare overall survival (OS) and progression free survival (PFS) distributions according to histology as well as treatment.
Results: Of 1139 patients including 716 men and 423 women, AC was the most common subtype (56.8%), followed by SCC (19.7%), O/NOS (17.0%) and LCC (6.5%). Men were more likely to have SCC and women were more likely to have AC (p = 0.002). Among the four histology groups, there was no imbalance in regard to race, performance status, weight loss, brain metastasis or treatment. In each histology group, we found no significant difference in OS and PFS between the four chemotherapy regimens. Conversely, in each treatment arm, the survival outcome was similar between the four histology subtypes.
Conclusions: Our analysis suggests that histology does not predict survival benefit in advanced NSCLC patients treated with first-line platin-based doublets involving paclitaxel, docetaxel or gemcitabine. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

AB Computer-aided detection/diagnosis (CAD) is increasingly used for decision support by clinicians for detection and interpretation of diseases. However, there are no quality assurance (QA) requirements for CAD in clinical use at present. QA of CAD is important so that end users can be made aware of changes in CAD performance both due to intentional or unintentional causes. In addition, end-user training is critical to prevent improper use of CAD, which could potentially result in lower overall clinical performance. Research on QA of CAD and user training are limited to date. The purpose of this paper is to bring attention to these issues, inform the readers of the opinions of the members of the American Association of Physicists in Medicine (AAPM) CAD subcommittee, and thus stimulate further discussion in the CAD community on these topics. The recommendations in this paper are intended to be work items for AAPM task groups that will be formed to address QA and user training issues on CAD in the future. The work items may serve as a framework for the discussion and eventual design of detailed QA and training procedures for physicists and users of CAD. Some of the recommendations are considered by the subcommittee to be reasonably easy and practical and can be implemented immediately by the end users; others are considered to be "best practice" approaches, which may require significant effort, additional tools, and proper training to implement. The eventual standardization of the requirements of QA procedures for CAD will have to be determined through consensus from members of the CAD community, and user training may require support of professional societies. It is expected that high-quality CAD and proper use of CAD could allow these systems to achieve their true potential, thus benefiting both the patients and the clinicians, and may bring about more widespread clinical use of CAD for many other diseases and applications. It is hoped that the awareness of the need for appropriate CAD QA and user training will stimulate new ideas and approaches for implementing such procedures efficiently and effectively as well as funding opportunities to fulfill such critical efforts.

AB Purpose: To investigate dosimetric errors in proton therapy treatment planning due to titanium implants, and to determine how these affect postoperative passively scattered proton therapy for chordoma patients with orthopedic hardware.
Methods: The presence of titanium hardware near the tumor may affect the dosimetric accuracy of proton therapy. Artifacts in the computed tomography (CT) scan can cause errors in the proton stopping powers used for dose calculation, which are derived from CT numbers. Also, clinical dose calculation algorithms may not accurately simulate proton beam transport through the implants, which have very different properties as compared to human tissue. The authors first evaluated the impact of these two main issues. Dose errors introduced by metal artifacts were studied using phantoms with and without titanium inserts, and patient scans on which a metal artifact reduction method was applied. Pencil-beam dose calculations were compared to models of nuclear interactions in titanium and Monte Carlo simulations. Then, to assess the overall impact on treatment plans for chordoma, the authors compared the original clinical treatment plans to recalculated dose distributions employing both metal artifact reduction and Monte Carlo methods.
Results: Dose recalculations of clinical proton fields showed that metal artifacts cause range errors up to 6 mm distal to regions affected by CT artifacts. Monte Carlo simulations revealed dose differences >10% in the high-dose area, and range differences up to 10 mm. Since these errors are mostly local in nature, the large number of fields limits the impact on target coverage in the chordoma treatment plans to a small decrease of dose homogeneity.
Conclusions: In the presence of titanium implants, CT metal artifacts and the approximations of pencil-beam dose calculations cause considerable errors in proton dose calculation. The spatial distribution of the errors however limits the overall impact on passively scattered proton therapy for chordoma. c 2013 American Association of Physicists in Medicine.

AB Purpose: The alpha-to-beta (alpha/beta) ratio for prostate tumor is likely lower than that for the surrounding normal organs, such as rectum and bladder (similar to 3 Gy). As a result, hypofractionation is expected to improve the therapeutic ratio in prostate radiation therapy. However, with the use of fewer, larger fractions, the accuracy of treatment dose delivery becomes more influenced by the physical uncertainties resulting from motion and radiobiological uncertainties in the alpha/beta ratio of the prostate tumor. The purpose of this study is to evaluate the impact of interfractional motion on treatment dose delivery within the likely range of the tumor alpha/beta ratio.
Methods: Serial CT images acquired at simulation and daily treatment for three prostate patients were studied retrospectively. A conventional 3D-conformal proton plan was created for each patient, delivering 25 fractions of 2 Gy to ITV1 (internal target volume, expanded from the prostate and clinically involved seminal vesicles) followed by 14 fractions to ITV2 (expanded from the prostate). The plans were renormalized for a series of hypofractionated protocols of between five and 28 fractions. The fractional doses were computed on daily CT and were mapped onto simulation CT using deformable registration. In each course, the doses from the fractions with the lowest D97% of the ITV2 were summed to approximate the lower limit (worst case) of target coverage. The uncertainty in dose and coverage was estimated as the deviation of the worst case from the nominal plan.
Results: For treatments in 28 to five fractions, the uncertainty arising from interfractional motion ranged from similar to 1% to 4% for V100% and similar to 2% to 6% for D100% of the ITV2. The uncertainties in V95% and D95% were both minimal (<1%) for all protocols. For tumors with a low alpha/beta of 1.0 Gy, the treatment in five fractions could deliver an additional 21.0 and 17.4 Gy(EQD2) to 95% and 100% of the ITV2, respectively, compared to that in 28 fractions. This advantage disappeared for tumors with alpha/beta > 2.5 Gy, assuming the worst case for interfractional motion.
Conclusions: In hypofractionated proton therapy for prostate cancer, the dosimetric uncertainties due to interfractional motion were minimal for the ITV2 coverage at 95% isodose level and the dose received by 95% of the ITV2. Although hypofractionation could yield an increase in equivalent dose to the target for tumors with low alpha/beta, the gain was cancelled out by the uncertainty due to interfractional motion for tumors with alpha/beta > 2.5 Gy. c 2013 American Association of Physicists in Medicine.

AB Purpose: The XCAT phantom is a realistic 4D digital torso phantom that is widely used in imaging and therapy research. However, lung mass is not conserved between respiratory phases of the phantom, making detailed dosimetric simulations and dose accumulation unphysical. A framework is developed to correct this issue by enforcing local mass conservation in the XCAT lung. Dose calculations are performed to assess the implications of neglecting mass conservation, and to demonstrate an application of the phantom to calculate the accumulated delivered dose in an irregularly breathing patient.
Methods: A displacement vector field (DVF) between each respiratory state and a reference image is generated from the XCAT motion model and its divergence is calculated and used to correct the lung density. A series of phantoms with regular and irregular breathing (based on patient data) are generated and modified to conserve mass. Monte Carlo methods are used to simulate conventional and SBRT treatment delivery. The calculated dose is deformed and accumulated using the DVF. Results from the mass-conserving and original XCAT are compared. A 4DCT is simulated for the irregularly breathing patient, and a 4DCT-based dose estimate is compared with the accumulated delivered dose.
Results: The presented framework successfully conserves mass in the XCAT lung. The spatial distribution of the lung dose was qualitatively changed by the use of a mass conservation in the XCAT; however, the corresponding DVH did not change significantly. The comparison of the delivered dose with the 4DCT-based prediction shows similar lung metric results, however dose differences of 10% can be seen in some spatial regions.
Conclusions: The XCAT phantom has been successfully modified so that it conserves lung mass during respiration, enabling it to be used as a tool to perform dose accumulation studies in the lung without relying on deformable image registration. Neglecting mass conservation can result in erroneous spatial distributions of the dose in the lung. Using this tool to simulate patient treatments reveals differences between the planned dose and the calculated delivered dose for the full treatment.

AB Tamoxifen resistance of estrogen receptor-positive (ER+) breast cancer cells has been linked in part to activation of receptor tyrosine kinases, such as HER2, and the PI3K-AKT pathway. Mucin 1 (MUC1) is aberrantly overexpressed in about 90% of human breast cancers, and the oncogenic MUC1-C subunit is associated with ER alpha. The present studies using HER2 overexpressing BT-474 breast cancer cells, which are constitutively resistant to tamoxifen, demonstrate that silencingMUC1-C is associated with (i) downregulation of p-HER2 and (ii) sensitivity to tamoxifen-induced growth inhibition and loss of clonogenic survival. In contrast, overexpression of MUC1-C in tamoxifen-sensitive MCF-7 breast cancer cells resulted in upregulation of p-AKT and tamoxifen resistance. We show that MUC1-C forms complexes with ER alpha on the estrogenresponsive promoter of Rab31 and that MUC1-C blocks tamoxifen-induced decreases in ER alpha occupancy. MUC1-C also attenuated tamoxifen-induced decreases in (i) recruitment of the coactivator CREB binding protein, (ii) Rab31 promoter activation, and (iii) Rab31 mRNA and protein levels. The importance of MUC1C is further supported by the demonstration that targeting MUC1-C with the cell-penetrating peptide inhibitor, GO-203, sensitized tamoxifen-resistant cells to tamoxifen treatment. Moreover, we show that targeting MUC1-C in combination with tamoxifen is highly synergistic in the treatment of tamoxifen-resistant breast cancer cells. Combined, these findings indicate that MUC1-C contributes to tamoxifen resistance.

AB Resistance to BRAF inhibitor therapy places priority on developing BRAF inhibitor-based combinations that will overcome de novo resistance and prevent the emergence of acquired mechanisms of resistance. The CRM1 receptor mediates the nuclear export of critical proteins required for melanoma proliferation, survival, and drug resistance. We hypothesize that by inhibiting CRM1-mediated nuclear export, we will alter the function of these proteins resulting in decreased melanoma viability and enhanced BRAF inhibitor antitumoral effects. To test our hypothesis, selective inhibitors of nuclear export (SINE) analogs KPT-185, KPT-251, KPT-276, and KPT-330 were used to induce CRM1 inhibition. Analogs PLX-4720 and PLX-4032 were used as BRAF inhibitors. Compounds were tested in xenograft and in vitro melanoma models. In vitro, we found CRM1 inhibition decreases melanoma cell proliferation independent of BRAF mutation status and synergistically enhances the effects of BRAF inhibition on BRAF-mutant melanoma by promoting cell-cycle arrest and apoptosis. In melanoma xenograft models, CRM1 inhibition reduces tumor growth independent of BRAF or NRAS status and induces complete regression of BRAF V600E tumors when combined with BRAF inhibition. Mechanistic studies show that CRM1 inhibition was associated with p53 stabilization and retinoblastoma protein (pRb) and survivin modulation. Furthermore, we found that BRAF inhibition abrogates extracellular signal-regulated kinase phosphorylation associated with CRM1 inhibition, which may contribute to the synergy of the combination. In conclusion, CRM1 inhibition impairs melanoma survival in both BRAF-mutant and wild-type melanoma. The combination of CRM1 and BRAF inhibition synergizes and induces melanoma regression in BRAF-mutant melanoma. (C) 2013 AACR.

AB To investigate the mechanism by which 5-aminoimidazole-4-carboxamide-1-beta-riboside (AICAr) induces apoptosis in multiple myeloma cells, we conducted an unbiased metabolomics screen. AICAr had selective effects on nucleotide metabolism, resulting in an increase in purine metabolites and a decrease in pyrimidine metabolites. The most striking abnormality was a 26-fold increase in orotate associated with a decrease in uridine monophosphate (UMP) levels, indicating an inhibition of UMP synthetase (UMPS), the last enzyme in the de novo pyrimidine biosynthetic pathway, which produces UMP from orotate and 5-phosphoribosyl-alpha-pyrophosphate (PRPP). As all pyrimidine nucleotides can be synthesized from UMP, this suggested that the decrease in UMP would lead to pyrimidine starvation as a possible cause of AICAr-induced apoptosis. Exogenous pyrimidines uridine, cytidine, and thymidine, but not purines adenosine or guanosine, rescued multiple myeloma cells from AICAr-induced apoptosis, supporting this notion. In contrast, exogenous uridine had no protective effect on apoptosis resulting from bortezomib, melphalan, or metformin. Rescue resulting from thymidine add-back indicated apoptosis was induced by limiting DNA synthesis rather than RNA synthesis. DNA replicative stress was identified by associated H2A. X phosphorylation in AICAr-treated cells, which was also prevented by uridine add-back. Although phosphorylation of AICAr by adenosine kinase was required to induce multiple myeloma cell death, apoptosis was not associated with AMP-activated kinase activation or mTORC1 inhibition. A possible explanation for inhibition of UMP synthase activity by AICAr was a depression in cellular levels of PRPP, a substrate of UMP synthase. These data identify pyrimidine biosynthesis as a potential molecular target for future therapeutics in multiple myeloma cells. (C) 2013 AACR.

AB The interaction between the HSP90 chaperone and its client kinases is sensitive to the conformational status of the kinase, and stabilization of the kinase fold by small molecules strongly decreases chaperone interaction. Here we exploit this observation and assay small-molecule binding to kinases in living cells, using chaperones as 'thermodynamic sensors'. The method allows determination of target specificities of both ATP-competitive and allosteric inhibitors in the kinases' native cellular context in high throughput. We profile target specificities of 30 diverse kinase inhibitors against >300 kinases. Demonstrating the value of the assay, we identify ETV6-NTRK3 as a target of the FDA-approved drug crizotinib (Xalkori). Crizotinib inhibits proliferation of ETV6-NTRK3-dependent tumor cells with nanomolar potency and induces the regression of established tumor xenografts in mice. Finally, we show that our approach is applicable to other chaperone and target classes by assaying HSP70/steroid hormone receptor and CDC37/kinase interactions, suggesting that chaperone interactions will have broad application in detecting drug-target interactions in vivo.

TI Zbtb7a suppresses prostate cancer through repression of a Sox9-dependent

AB Zbtb7a has previously been described as a powerful proto-oncogene. Here we unexpectedly demonstrate that Zbtb7a has a critical oncosuppressive role in the prostate. Prostate-specific inactivation of Zbtb7a leads to a marked acceleration of Pten loss-driven prostate tumorigenesis through bypass of Pten loss-induced cellular senescence (PICS). We show that ZBTB7A physically interacts with SOX9 and functionally antagonizes its transcriptional activity on key target genes such as MIA, which is involved in tumor cell invasion, and H19, a long noncoding RNA precursor for an RB-targeting microRNA. Inactivation of Zbtb7a in vivo leads to Rb downregulation, PICS bypass and invasive prostate cancer. Notably, we found that ZBTB7A is genetically lost, as well as downregulated at both the mRNA and protein levels, in a subset of human advanced prostate cancers. Thus, we identify ZBTB7A as a context-dependent cancer gene that can act as an oncogene in some contexts but also has oncosuppressive-like activity in Pten-null tumors.

AB Here we report an integrated analysis that leverages data from treatment of genetic mouse models of prostate cancer along with clinical data from patients to elucidate new mechanisms of castration resistance. We show that castration counteracts tumor progression in a Pten loss-driven mouse model of prostate cancer through the induction of apoptosis and proliferation block. Conversely, this response is bypassed with deletion of either Trp53 or Zbtb7a together with Pten, leading to the development of castration-resistant prostate cancer (CRPC). Mechanistically, the integrated acquisition of data from mouse models and patients identifies the expression patterns of XAF1, XIAP and SRD5A1 as a predictive and actionable signature for CRPC. Notably, we show that combined inhibition of XIAP, SRD5A1 and AR pathways overcomes castration resistance. Thus, our co-clinical approach facilitates the stratification of patients and the development of tailored and innovative therapeutic treatments.

AB Epileptic encephalopathies are a devastating group of epilepsies with poor prognosis, of which the majority are of unknown etiology. We perform targeted massively parallel resequencing of 19 known and 46 candidate genes for epileptic encephalopathy in 500 affected individuals (cases) to identify new genes involved and to investigate the phenotypic spectrum associated with mutations in known genes. Overall, we identified pathogenic mutations in 10% of our cohort. Six of the 46 candidate genes had 1 or more pathogenic variants, collectively accounting for 3% of our cohort. We show that de novo CHD2 and SYNGAP1 mutations are new causes of epileptic encephalopathies, accounting for 1.2% and 1% of cases, respectively. We also expand the phenotypic spectra explained by SCN1A, SCN2A and SCN8A mutations. To our knowledge, this is the largest cohort of cases with epileptic encephalopathies to undergo targeted resequencing. Implementation of this rapid and efficient method will change diagnosis and understanding of the molecular etiologies of these disorders.

AB Transposable element (TE)-derived sequences comprise half of the human genome and DNA methylome and are presumed to be densely methylated and inactive. Examination of genome-wide DNA methylation status within 928 TE subfamilies in human embryonic and adult tissues identified unexpected tissue-specific and subfamily-specific hypomethylation signatures. Genes proximal to tissue-specific hypomethylated TE sequences were enriched for functions important for the relevant tissue type, and their expression correlated strongly with hypomethylation within the TEs. When hypomethylated, these TE sequences gained tissue-specific enhancer marks, including monomethylation of histone H3 at lysine 4 (H3K4me1) and occupancy by p300, and a majority exhibited enhancer activity in reporter gene assays. Many such TEs also harbored binding sites for transcription factors that are important for tissue-specific functions and showed evidence of evolutionary selection. These data suggest that sequences derived from TEs may be responsible for wiring tissue type-specific regulatory networks and may have acquired tissue-specific epigenetic regulation.

AB Intrinsic functional connectivity magnetic resonance imaging (fcMRI) has emerged as a powerful tool for mapping large-scale networks in the human brain. Robust and reliable functionally coupled networks can be detected in individuals that echo many known features of anatomical organization. Features of brain organization have been discovered, including descriptions of distributed large-scale networks interwoven throughout association cortex, interactions (including anticorrelations) between brain networks and insights into the topography of subcortical structures. But interpreting fcMRI is complicated by several factors. Functional coupling changes dynamically, suggesting that it is constrained by, but not fully dictated by, anatomic connectivity. Critically to study of between-group differences, fcMRI is sensitive to head motion and to differences in the mental states of participants during the scans. We discuss the potential of fcMRI in the context of its limitations.

AB In our functional dissection of the CD33 Alzheimer's disease susceptibility locus, we found that the rs3865444(C) risk allele was associated with greater cell surface expression of CD33 in the monocytes ( t(50) = 10.06, P-joint = 1.3 x 10(-13)) of young and older individuals. It was also associated with diminished internalization of amyloid-beta 42 peptide, accumulation of neuritic amyloid pathology and fibrillar amyloid on in vivo imaging, and increased numbers of activated human microglia.

AB The peripheral terminals of primary sensory neurons detect histamine and non-histamine itch-provoking ligands through molecularly distinct transduction mechanisms. It remains unclear, however, whether these distinct pruritogens activate the same or different afferent fibers. Using a strategy of reversibly silencing specific subsets of murine pruritogen-sensitive sensory axons by targeted delivery of a charged sodium-channel blocker, we found that functional blockade of histamine itch did not affect the itch evoked by chloroquine or SLIGRL-NH2, and vice versa. Notably, blocking itch-generating fibers did not reduce pain-associated behavior. However, silencing TRPV1(+) or TRPA1(+) neurons allowed allyl isothiocyanate or capsaicin, respectively, to evoke itch, implying that certain peripheral afferents may normally indirectly inhibit algogens from eliciting itch. These findings support the presence of functionally distinct sets of itch-generating neurons and suggest that targeted silencing of activated sensory fibers may represent a clinically useful anti-pruritic therapeutic approach for histaminergic and non-histaminergic pruritus.

AB Untreated HIV-1 infection typically progresses to AIDS within 10 years, but less than 1% of infected individuals remain healthy and have normal CD4(+) T cell counts and undetectable viral loads; some individuals have remained this way for 35 years and counting. Through a combination of large population studies of cohorts of these 'HIV-1 controllers' and detailed studies of individual patients, a heterogeneous picture has emerged regarding the basis for this remarkable resistance to AIDS progression. In this Review, we highlight the host genetic factors, the viral genetic factors and the immunological factors that are associated with the controller phenotype, we discuss emerging methodological approaches that could facilitate a better understanding of spontaneous HIV-1 immune control in the future, and we delineate implications for a 'functional cure' of HIV-1 infection.

AB Researchers have begun to characterize the subtle biological and cognitive processes that precede the clinical onset of Alzheimer disease (AD), and to set the stage for accelerated evaluation of experimental treatments to delay the onset, reduce the risk of, or completely prevent clinical decline. In this Review, we provide an overview of the experimental strategies, and brain imaging and cerebrospinal fluid biomarker measures that are used in early detection and tracking of AD, highlighting at-risk individuals who could be suitable for preclinical monitoring. We discuss how advances in the field have contributed to reconceptualization of AD as a sequence of biological changes that occur during progression from preclinical AD, to mild cognitive impairment and finally dementia, and we review recently proposed research criteria for preclinical AD. Advances in the study of preclinical AD have driven the recognition that efficacy of at least some AD therapies may depend on initiation of treatment before clinical manifestation of disease, leading to a new era of AD prevention research.

AB Objective: Little is known about how patient-clinician communication leads to better outcomes. Among patients with diabetes, we describe patient-reported use of collaborative goal setting and evaluate whether perceived competency and physician trust mediate the association between collaborative goal setting and glycemic control.
Methods: Data from a patient survey administered in 2008 to a cohort of insured patients aged 18+ years with diabetes who initiated oral mono-therapy between 2000 and 2005 were joined with pharmaceutical claims data for the prior 12 months and laboratory data for the prior and subsequent 12 months (N = 1065). A structural equation model (SEM) was used to test mediation models controlling for baseline HbA1c.
Results: The hypothesized mediation model was supported. Patient-reported use of more collaborative goal setting was associated with greater perceived self-management competency and increased level of trust in the physician (p < 0.05). In turn, both greater perceived competence and increased trust were associated with increased control (p < 0.05).
Conclusions: Findings indicate that engaging patients in collaborative goal setting during clinical encounters has potential to foster a trusting patient-clinician relationship as well as enhance patient perceived competence, thereby improving clinical control.
Practice implications: Fostering collaborative goal setting may yield payoffs in improved clinical outcomes among patients with diabetes. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

POPULATION; MORTALITY; OUTCOMES; WOMEN
AB Objective: Social determinants, such as socioeconomic status (SES) and race/ethnicity are linked to striking health disparities across the cancer continuum. One important mechanism linking social determinants and health disparities may be communication inequalities that are caused by differences in accessing, processing and utilizing cancer information. In this context, we examined health information-seeking/avoidance as a potential mediator between social determinants and self-rated health (SRH) status among cancer survivors.
Methods: Data came from the 2008 well-informed, thriving and surviving (WITS) study of post-treatment cancer survivors (n = 501). We examined the mediating effect of health communication-related behavior between SES and disparities in SRH.
Results: The likelihood of belonging to the Low SRH group was higher among patients who had avoided health information and whose family members had not sought health information on behalf of the survivor, those in the lowest household income bracket, and those who had high school or less education after adjusting for potential confounders.
Conclusion: Differences in SRH among cancer survivors are associated with SES as well as communication inequalities.
Practice implications: It is necessary to provide a supportive environment in which health information is made available if disparities in health-related quality of life among cancer survivors are to be reduced. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

AB BACKGROUND: Cerebrospinal fluid (CSF) biomarkers reflecting neuronal and astroglial injury, such as total tau (T-tau), glial flbrillary acidic protein (GFAP), and neurofilament light (NFL), have been extensively investigated in neurologic diseases in adults, but no large study has investigated these biomarkers in children. METHODS: This study presents a detailed evaluation of CFS T-tau, GFAP, NFL, and CSF:albumin ratio in a large cohort of pediatric patients. This is a retrospective multicenter study on pediatric patients aged <16 years (n = 607), where neuronal injury biomarkers T-tau, GFAP, NFL, and CSF albumin ratio were analyzed during 2000-2010 at the Clinical Neurochemistry Laboratory, Sahlgrenska University Hospital, Sweden. The patients were grouped into eight categories: epilepsy, infectious and inflammatory central nervous system disorders, progressive encephalopathy, static encephalopathy, tumors, movement disorders, miscellaneous disorders, and a control group. RESULTS: T-tau, GFAP, and NFL were increased in progressive encephalopathy (P < 0.001), epilepsy (P < 0.001), and infectious and inflammatory central nervous system disorders (P < 0.001) compared with controls. T-tau was the biomarker with the highest diagnostic accuracy with the area under the curve of 0.83 (95% confidence interval (CI), 0.77-0.90; P < 0.0001) for progressive encephalopathy followed by epilepsy 0.80 (95% CI, 0.75-0.87; P < 0.0001). The combination of all four biomarkers further improved the area under the curve for the progressive encephalopathy 0.87 (95% CI, 0.77-0.89; P < 0.0001), followed by epilepsy 0.81 (95% CI, 0.74-0.80; P = 0.030). The combination of the biomarkers also separated progressive from static encephalopathy 0.88 (95% CI, 0.83-0.93; P < 0.0001). CONCLUSIONS: CSF T-tau, GFAP, and NFL are differently altered across different neurologic diseases in children. Importantly, the biomarker pattern distinguishes between progressive and static neurologic disorders. (c) 2013 Elsevier Inc. All rights reserved.

ID ATTENTION-DEFICIT/HYPERACTIVITY DISORDER; POSTNATAL-DEVELOPMENT;
CHILDREN; RECEPTORS; DYSTONIA; CORTEX
AB BACKGROUND: Acute dyskinetic or dystonic reactions are a long-recognized complication of medications that alter dopamine signaling. Most reactions occur following exposure to agents that block dopamine receptors (e.g., neuroleptics). However, agents that increase dopaminergic transmission (such as methylphenidate) can also trigger acute dyskinesias. This has been previously reported only in patients also taking dopamine antagonists or, less commonly, in children with developmental abnormalities. CASE DESCRIPTION: The present report describes a previously healthy toddler who developed transient torticollis and orolingual dyskinesias following accidental exposure to methylphenidate. He had no preexisting movement disorder, central nervous system injury, or developmental abnormalities-in short, none of the previously reported risk factors for this side effect. HYPOTHESIS AND CONCLUSIONS: The unique features of this case led to the hypothesis that developmental shifts in dopamine signaling were the basis for his particular sensitivity to methylphenidate. If confirmed, this hypothesis has implications for the treatment of common childhood attentional and behavioral disorders. The article includes a literature review of dyskinetic/dystonic reactions in children and the developmental regulation of dopamine metabolism. (c) 2013 Elsevier Inc. All rights reserved.

AB Tissue repair and regendation are essential processes in maintaining tissue homeostasis, especially in response to injury or stress. Eicosanoids are ubiquitous mediators of cell proliferation, differentiation, and angiogenesis, all of which are important for tissue growth. Eicosanoids regulate the induction and resolution of inflammation that accompany the tissue response to injury. In this review, we describe how this diverse group of molecules is a key regulator of tissue repair and regeneration in multiple organ systems and biologic contexts. (C) 2013 Elsevier Inc.

TI Diagnostic Reference Ranges for Pediatric Abdominal CT

DT Article
ID RADIATION-DOSE REDUCTION; COMPUTED-TOMOGRAPHY; EXPOSURE; RISK; AGE
AB Purpose: To develop diagnostic reference ranges (DRRs) and a method for an individual practice to calculate site-specific reference doses for computed tomographic (CT) scans of the abdomen or abdomen and pelvis in children on the basis of body width (BW).
Materials and Methods: This HIPAA-compliant multicenter retrospective study was approved by institutional review boards of participating institutions; informed consent was waived. In 939 pediatric patients, CT doses were reviewed in 499 (53%) male and 440 (47%) female patients (mean age, 10 years). Doses were from 954 scans obtained from September 1 to December 1, 2009, through Quality Improvement Registry for CT Scans in Children within the National Radiology Data Registry, American College of Radiology. Size-specific dose estimate (SSDE), a dose estimate based on BW, CT dose index, dose-length product, and effective dose were analyzed. BW measurement was obtained with electronic calipers from the axial image at the splenic vein level after completion of the CT scan. An adult-sized patient was defined as a patient with BW of 34 cm. An appropriate dose range for each DRR was developed by reviewing image quality on a subset of CT scans through comparison with a five-point visual reference scale with increments of added simulated quantum mottle and by determining DRR to establish lower and upper bounds for each range.
Results: For 954 scans, DRRs (SSDEs) were 5.8-12.0, 7.3-12.2, 7.6-13.4, 9.8-16.4, and 13.1-19.0 mGy for BWs less than 15, 15-19, 20-24, 25-29, and 30 cm or greater, respectively. The fractions of adult doses, adult SSDEs, used within the consortium for patients with BWs of 10, 14, 18, 22, 26, and 30 cm were 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9, respectively.
Conclusion: The concept of DRRs addresses the balance between the patient's risk (radiation dose) and benefit (diagnostic image quality). Calculation of reference doses as a function of BW for an individual practice provides a tool to help develop site-specific CT protocols that help manage pediatric patient radiation doses.

SO RADIOLOGY
LA English
DT Article
ID GLAND; TRANSPLANTATION; PREGNANCY
AB Purpose: To determine whether there is a sex difference in the appearance of the normal thymus in 20-30-year-old men and women.
Materials and Methods: This retrospective study was approved by the institutional review board and was compliant with HIPAA. The requirement for informed consent was waived. Images and medical records of 238 consecutive subjects without known thymic disease (175 men, 63 women) who underwent chest computed tomography with intravenous contrast material in 2008 were reviewed. Average thymic region of interest (ROI), subjective assessment of thymic attenuation by using a scale of grades 0-3, thymic anteroposterior measurement, and mean maximal thymic lobe thickness were recorded by two independent thoracic radiologists, blinded to subject age and sex. Thymic morphologic characteristics were assessed in consensus. The two-sided Wilcoxon rank-sum test, Student t test, test for linear regression, analysis of covariance, two-way factorial analysis of variance, and continuity-adjusted chi(2) test were used for statistical analysis.
Results: There was a significant sex difference in thymic attenuation as measured objectively by using mean thymic ROI measurement (P < .0001) and subjectively by using a scale of grades 0-3 (P,.0001), which held true when corrected for age (P,.0001). A sex difference was also found in regard to the rate of decrease in mean thymic attenuation with age, with men's thymuses exhibiting a significant decrease in attenuation during the decade, unlike women (P = .0479). There was no significant sex difference in mean maximal thymic lobe thickness (P = .8697). A quadrilateral, as opposed to triangular, configuration of the thymus was more common in women than men (P = .0034).
Conclusion: There is a significant sex difference in normal thymic appearance in 20-30-year-old men and women. The thymus of 20-30-year-old women typically exhibits higher attenuation and more commonly exhibits a quadrilateral configuration. (C) RSNA, 2013

AB The Veterans Health Administration (VHA) is a large integrated healthcare system with a mission to care for over 5.6 million Veteran patients annually. VHA, like other healthcare organizations, is challenged with providing access to care to those it serves when they live at a distance from a physical site of care. VHA has embraced telehealth as a way of delivering care at a distance and increase access to specialty care services. Since 2003 VHA has developed large national telehealth networks that provided care to 497,342 patients in fiscal year 2012, who received 1,429,424 episodes of care, and is recognized as a national leader in this field. To ensure the safety and effectiveness of its telehealth networks in their delivery of care VHA has implemented a dedicated quality management (QM) program for telehealth. QM data for telehealth are reviewed at 3-month intervals, and the procedures and processes in place to support telehealth in VHA are assessed biannually in an internal accreditation process called "Telehealth Conditions of Participation." This collegial, nonadversarial process has ensured that all designated telehealth programs meet minimal standards and disseminate best practice. As a result of VHA's QM program, telehealth services in VHA meet consistently high clinical outcomes and have received no adverse Joint Commission citations. The Joint Commission regularly assesses patients managed via telehealth under its tracer methodology reviews.

AB Background: Autoimmune and non-autoimmune thyroiditis frequently occur in persons with hepatitis C virus (HCV) infection. Treatment with interferon alpha (IFN alpha) is also associated with significant risk for the development of thyroiditis. To explore HCV-thyroid interactions at a cellular level, we evaluated whether a human thyroid cell line (ML1) could be infected productively with HCV in vitro.
Methods and Results: ML1 cells showed robust surface expression of the major HCV receptor CD81. Using a highly sensitive, strand-specific reverse transcription polymerase chain reaction assay, positive-sense and negative-sense HCV RNA were detected in ML1 cell lysates at days 3, 7, and 14 postinfection with HCV. HCV core protein was expressed at high levels in ML1 supernatants at days 1, 3, 5, 7, and 14 postinfection. The nonstructural protein NS5A was also detected in ML1 cell lysates by Western blotting. HCV entry into ML1 cells was shown to be dependent on the HCV entry factors CD81 and SR-B1/CLA1, while IFN alpha inhibited HCV replication in ML1 cells in a dose-dependent manner. Supernatants from HCV-infected ML1 cells were able to infect fresh ML1 cells productively, suggesting that infectious virions could be transferred from infected to naive thyroid cells in vivo. Additionally, HCV infection of ML1 cells led to increased expression of the proinflammatory cytokine IL-8.
Conclusions: For the first time, we have demonstrated that HCV can infect human thyroid cells in vitro. These findings strongly suggest that HCV infection of thyrocytes may play a role in the association between chronic HCV infection and thyroid autoimmunity. Furthermore, the thyroid may serve as an extrahepatic reservoir for HCV viral replication, thus contributing to the persistence of viral infection and to the development of thyroid autoimmunity.

AB Objectives: We sought to develop a clinical algorithm combining serum PSA with detection of TMPRSS2:ERG fusion and PCA3 in urine collected after digital rectal exam (post-DRE urine) to predict prostate cancer on subsequent biopsy.
Materials and methods: Post-DRE urine was collected in 48 consecutive patients before prostate biopsy at 2 centers; quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect PCA3 and TMPRSS2:ERG fusion transcript expression. Serum PSA was measured by clinical assay. The performance of TMPRSS2:ERG fusion, PCA3, and serum PSA as biomarkers predicting prostate cancer at biopsy was measured; a clinically practical algorithm combining serum PSA with TMPRSS2:ERG and PCA3 in post-DRE urine to predict prostate cancer was developed.
Results: Post-DRE urine sediment provided informative RNA in 45 patients; prostate cancer was present on subsequent biopsy in 15. TMPRSS2:ERG in post-DRE urine was associated with prostate cancer (OR = 12.02; P < 0.001). PCA3 had the highest sensitivity in predicting prostate cancer diagnosis (93%), whereas TMPRSS2:ERG had the highest specificity (87%). TMPRSS2:ERG had the greatest discriminatory value in predicting prostate cancer (AUC = 0.77 compared with 0.65 for PCA3 and 0.72 for serum PSA alone). Combining serum PSA, PCA3, and TMPRSS2:ERG in a multivariable algorithm optimized for clinical utility improved cancer prediction (AUC = 0.88; specificity = 90% at 80% sensitivity).
Conclusions: A clinical algorithm specifying biopsy for all patients with PSA >= 10 ng/ml, while restricting biopsy among those with PSA <10 ng/ml to only those with detectable PCA3 or TMPRSS2:ERG in post-DRE urine, performed better than the individual biomarkers alone in predicting prostate cancer.

AB Objective The importance of tear film integrity to ocular health in terrestrial mammals is well established, however, in marine mammals, the role of the tear film in protection of the ocular surface is not known. In an effort to better understand the function of tears in maintaining health of the marine mammal eye surface, we examined ocular glands of the California sea lion and began to characterize the biochemical nature of the tear film of pinnipeds.
Procedures Glands dissected from California sea lion eyelids and adnexa were examined for gross morphology, sectioned for microscopic analysis, and stained with hematoxylin and eosin. The tear film was examined using interferometry. Tears were collected from humans and pinnipeds for the analysis of protein and carbohydrate content.
Results The sea lion has sebaceous glands in the lid, but these glands are different in size and orientation compared with typical meibomian glands of terrestrial mammals. Two other accessory ocular glands located dorsotemporally and medially appeared to be identical in morphology, with tubulo-acinar morphology. An outer lipid layer on the ocular surface of the sea lion was not detected using interferometry, consistent with the absence of typical meibomian glands. Similar to human tears, the tears of pinnipeds contain several proteins but the ratio of carbohydrate to protein was greater than that in human tears.
Conclusions Our findings indicate that the ocular gland architecture and biochemical nature of the tear film of pinnipeds have evolved to adapt to the challenges of an aquatic environment.

AB Background Alcohol use disorders are related to neurocognitive abnormalities during early abstinence in those seeking treatment for alcohol dependence (ALC). Considerable evidence indicates that chronic cigarette smoking is associated with multiple neurocognitive deficiencies. However, very little is known about the effects of chronic smoking on neurocognitive recovery during early abstinence from alcohol. We evaluated whether cigarette smoking interferes with cognitive improvement during early abstinence from alcohol, a period thought important for maintaining long-term sobriety.
Methods Neurocognitive functions previously shown to be adversely affected by both alcohol use disorders and chronic cigarette smoking were evaluated. We assessed 35 smoking ALC (sALC) and 34 nonsmoking ALC (nsALC) at approximately 1 and 5weeks of monitored abstinence.
Results Although neither group was clinically impaired, both cross-sectional and longitudinal deficiencies were observed in sALC versus nsALC in processing speed, working memory, and auditory-verbal learning and memory. Lifetime alcohol consumption, medical, and psychiatric comorbidities did not predict neurocognitive performance or improvement across assessments. Within sALC, greater drinking and smoking severities were synergistically (more than additively) related to less improvement on visuospatial learning and memory. Former smoking status in the nsALC-mediated group differences in auditory-verbal delayed recall.
Conclusions Chronic cigarette smoking appears to negatively impact neurocognition during early abstinence from alcohol. Although the cognitive deficiencies observed in this cohort were not in a clinical range of impairment, they should be considered to enhance treatment efficacy. Our findings lend support to integrating smoking cessation as well as the individual assessment of cognition into early ALC treatment. Additionally, there is a need to elucidate the effects of current and former smoking status in future reports of neurocognition.

AB Background Atrial fibrillation (AF)-related symptoms and physical performance are relied upon to guide therapeutic management of patients with AF. We sought to understand whether AF predisposes to or is a result of physical disability and poor subjective health in the community.
Methods We studied relations between physical disability (Rosow-Breslau Functional Health Scale), subjective health (self-report) and incident AF, and the converse, in the Framingham Heart Study.
Results In 3,609 participants (age 73 +/- 8 years, 59% women), a subset of 861 participants (24%) had prevalent physical disability at baseline. During 5.8 +/- 1.8 years of follow-up, 555 participants (10-year age-and sex-adjusted incidence rate 13%) developed incident AF. Prevalent physical disability was related to incident AF (multivariable-adjusted hazard ratio 1.25, 95% CI 1.02-1.54, P =.03). In 3,525 participants, prevalent poor subjective health (n = 333) also was related to incident AF (n = 552, multivariable-adjusted hazard ratio 1.31, 95% CI 1.00-1.70, P =.048). Conversely, in 2,080 participants (age 69 +/- 6 years, 55% women), interim AF (n = 106) was associated with newly reported physical disability (n = 573) at a follow-up examination (multivariable-adjusted odds ratio 1.58, 95% CI 1.08-2.31, P =.01). In 1,954 participants, interim AF (n = 96) likewise was related to newly reported poor subjective health (n = 224, multivariable-adjusted odds ratio 1.83, 95% CI 1.10-3.02, P = .02).
Conclusions Physical disability and poor subjective health were related to incident AF in a community-based cohort. Conversely, interim AF was related to newly reported physical disability and poor subjective health. Because AF guidelines incorporate symptoms, it is essential to clarify the temporality and mechanisms linking physical disability, subjective health, and AF.

AB With looming financial penalties for institutions with high readmission rates, hospital administrators are under pressure to implement strategies to reduce readmissions despite limited evidence of effective strategies. The objectives of this study were to understand the process of developing readmission reduction strategies and to identify and categorize the range of strategies being implemented. The authors designed a qualitative study using semistructured interviews with 12 hospital administrators at 6 different hospitals. The following 6 categories of strategies were identified: (a) tracking readmissions, (b) using prediction tools, (c) implementing disease-specific or generic readmission reduction programs, (d) adopting electronic health record-based strategies to improve transitions, (e) recruiting frontline staff for program leadership, and (f) coordinating with primary care providers. The results highlight the myriad approaches to readmission reduction and the complexity of developing effective strategies.

DE postoperative respiratory failure; patient safety; adverse events;
quality of care; quality indicators
AB The Patient Safety Indicator postoperative respiratory failure (PRF) flags cases using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for acute respiratory failure or mechanical ventilation/intubation. The authors examined how frequently PRF missed events and ways to improve event identification. A total of 125 high-risk unflagged cases were selected based on predicted probability and presence of clinically relevant codes. False-negative (FN) proportion and associated reasons were determined through chart review, and likelihood ratios (LRs) of associated codes were calculated. In all, 27% of elective cases were FNs; 55% of FNs lacked ventilation/intubation codes. Respiratory arrest, 799.1, had the highest LR (5.4) but occurred in only 8% of FNs. All other individual diagnostic or procedure codes had relatively low LRs (3.1), despite occurring in up to 36% of FNs. Among high-risk cases, the PRF algorithm often missed events. Improved ventilation/intubation coding will have more of an impact on case identification than adding ICD-9-CM codes to the algorithm.

CRITICAL-CARE; D DEFICIENCY; RISK; ASSOCIATION; MICE
AB OBJECTIVE: The study objective was to examine the association between pre-hospital serum vitamin D concentration and mortality after hospitalization.
METHODS: We performed a retrospective cohort study in 2 tertiary hospitals in Boston, Mass, on 23,603 patients aged >= 18 years in whom 25(OH) D was measured before hospitalization between 1993 and 2010. The main outcome measures were all-cause mortality by day 30 post-hospital admission, in-hospital mortality, and community-acquired bloodstream infection.
RESULTS: Compared with patients with pre-hospital 25(OH) D >= 30 ng/mL, patients with pre-hospital 25(OH) D <= 15 ng/mL or 15 to 30 ng/mL have higher odds of mortality 30 days after hospital admission. After adjustment for age, gender, race, Deyo-Charlson index, season, type (surgical vs medical), creatinine, blood urea nitrogen, hematocrit, and time between 25(OH) D draw and hospital admission, the adjusted odds ratio (OR) of 30-day mortality in patients with 25(OH) D <= 15 ng/mL is 1.45 (95% confidence interval [CI], 1.21-1.74; P<.0001) and the adjusted OR of 30-day mortality in patients with 25(OH) D 15 to 30 ng/mL is 1.30 (95% CI, 1.10-1.54; P = .003) both compared with patients with pre-hospital 25(OH) D >= 30 ng/mL. In a subgroup analysis of patients who had blood cultures drawn (n = 5628), pre-hospital serum 25(OH) D <= 15 ng/mL was associated with increased odds of community-acquired bloodstream infection (adjusted OR, 1.29; 95% CI, 1.06-1.57; P = .01) relative to patients with 25(OH) D >= 30 ng/mL.
CONCLUSIONS: Analysis of 23,603 hospitalized patients identified both 25(OH) D <= 15 ng/mL and 25(OH) D 15 to 30 ng/mL before hospital admission as associated with the odds of all-cause patient mortality at 30 days after hospitalization. In addition, pre-hospital serum 25(OH) D <= 15 ng/mL is significantly associated with the odds of community-acquired bloodstream infection. (C) 2013 Elsevier Inc. All rights reserved.

AB Objective: The authors examined whether D-cycloserine, a partial agonist at the glutamatergic N-methyl-D-aspartate receptor, augments and accelerates a full course of comprehensive cognitive-behavioral therapy (CBT) in adults with generalized social anxiety disorder.
Method: This was a multisite randomized placebo-controlled efficacy study with 169 medication-free adults with generalized social anxiety disorder, of whom 144 completed the 12-week treatment and 131 completed the three follow-up assessments. Patients were randomly assigned to receive 50 mg of D-cycloserine or placebo 1 hour before each of five exposure sessions that were part of a 12-session cognitive-behavioral group treatment. Response and remission status was determined at baseline, throughout treatment, at end of treatment, and at 1-, 3-, and 6-month follow-up assessments by assessors who were blind to treatment condition.
Results: D-Cycloserine-augmented and placebo-augmented CBT were associated with similar completion rates (87% and 82%), response rates (79.3% and 73.3%), and remission rates (34.5% and 24.4%) at the posttreatment assessment; response and remission rates were largely maintained at the follow-up assessments. Although D-cycloserine was associated with a 24%-33% faster rate of improvement in symptom severity and remission rates relative to placebo during the treatment phase, the groups did not differ in response and remission rates.
Conclusions: D-Cycloserine did not augment a full course of comprehensive CBT for social anxiety disorder.

AB Locoregional recurrence (LRR) rates following preoperative radiation therapy (RT) and radical resection for retroperitoneal sarcoma (RPS) are high. Targeted radiation dose escalation has been proposed as a means to decrease LRR, but is applicable only if LRRs are confined to within the RT field. We analyzed predictors for LRR and examined LRR locations to determine the potential benefit of dose escalation.
For 33 patients treated with preoperative RT and radical resection, we determined high-risk tumor volumes appropriate for boost and identified the number of recurrences within this volume. Clinical and pathologic variables predictive of overall survival (OS), freedom from progression (FFP), LRR, and distant recurrence (DR) were evaluated.
Median follow-up was 32.9 months. At 1 and 3 years, OS was 87 and 64 %, FFP rates were 71 and 45 %, cumulative incidences of LRR were 19 and 37 %, and of DR were 13 and 21 %. On multivariate analysis, multifocal disease was a significant predictor of increased incidence of LRR. At first relapse, 6 patients had isolated LR, 2 isolated RR, 6 isolated DR, 1 synchronous LR and RR, and 1 synchronous LR, RR, and DR. Ultimately, 4 patients (25 % of those who recurred) had isolated in-field recurrences within the hypothetical high-risk dose-painting boost volumes and that thus might have been prevented with dose-escalation.
Following preoperative RT and resection, LRR rates are high and associated with multifocal disease. Preoperative dose escalation to high-risk tumor volumes may perhaps benefit only a limited subset of patients, and therefore strategies are needed to select appropriate patients for consideration of this approach.

AB Paratesticular liposarcoma (LPS) is a rare entity for which optimal treatment has not been defined. We sought to determine recurrence patterns and prognostic factors.
A total of 25 patients with localized paratesticular LPS between 1987 and 2009 were reviewed. Actuarial local-recurrence-free survival (LRFS), disease-free-survival (DFS), and overall survival (OS) were determined using the Kaplan-Meier method.
LPS histology was well differentiated for 10 patients (40 %), de-differentiated for 14 (56 %), and pleomorphic for 1 (4 %). Final margins were positive in 8 patients (32 %). Radiation therapy (RT) was given to 10 patients; fields included inguinal canal +/- A scrotum and low pelvis. LRFS rates at 3 and 5 years were 76 and 67 %. The 3-year LRFS rates were lower in patients with positive margins compared with those with negative margins (29 vs 100 %, p = .0005) and in patients with recurrent versus primary disease (38 vs 83 %, p = .04). Among patients who received surgery and RT, margins remained a significant predictor of local recurrence (p = .009). Interestingly, recurrences in 4 patients tracked along gonadal vessels, and only 1 patient had a distant recurrence. OS at 5 years was 100 %.
For patients with localized paratesticular LPS, positive margins and presentation with recurrent disease are adverse prognostic factors for LRFS. LR for patients with positive margins is still high despite RT; thus aggressive surgery to attain negative margins should be attempted in all cases. The finding of regional recurrences along gonadal vessels should be validated, and imaging studies should be tailored to reflect potential patterns of disease at presentation and subsequent recurrence.

AB The benefit of adjuvant treatment in gastric adenocarcinoma was demonstrated by randomized, controlled trials of patients with locally advanced tumors. Thus, its role for stage IIB-IIIC disease is widely accepted. We aimed to identify patients with stage IA-IIA gastric adenocarcinoma who have a poor prognosis and thus may benefit from adjuvant treatment.
Patients with gastric adenocarcinoma who underwent surgical resection with pathological evaluation of a parts per thousand yen15 lymph nodes and had available disease-specific survival (DSS) data were identified from the Surveillance Epidemiology and End Results Registry. Survival differences were evaluated with the log-rank test and Cox multivariate analysis.
Stage and TN grouping strongly predicted DSS (P < 0.001, P < 0.001). Stage IA tumors had an excellent outcome: 91 +/- A 1.2 % 5-year DSS. The TN groupings of stages IB and IIA had the next best outcomes with 5-year DSS from 66 +/- A 4.6 % to 81 +/- A 2.3 %. Older age (P < 0.001), higher grade (P = 0.004), larger tumor size (P < 0.001), and proximal tumor location (P < 0.001) were independent predictors of worse DSS in stage IB-IIA tumors. We devised a risk stratification scheme for stage IB-IIA tumors where 1 point was assigned for age > 60 years, tumor size > 5 cm, proximal tumor location, and grade other than well-differentiated. Five-year DSS was 100 % for patients with 0 points; 86 +/- A 4.3 %, 1 point; 76 +/- A 3 %, 2 points; 72 +/- A 2.8 %, 3 points; and 48 +/- A 4.9 %, 4 points (P < 0.001).
Patients with stage IB-IIA gastric adenocarcinoma and a parts per thousand yen2 adverse features (age > 60 years, tumor size > 5 cm, proximal location, and high-grade) have 5-year DSS a parts per thousand currency sign76 %. Adjuvant therapy may be warranted for these patients.

AB Aims: Brown adipose tissue dissipates chemical energy in the form of heat and regulates triglyceride and glucose metabolism in the body. Factors that regulate fatty acid uptake and oxidation in brown adipocytes have not yet been fully elucidated. Bone morphogenetic protein 7 (BMP7) is a growth factor capable of inducing brown fat mitochondrial biogenesis during differentiation from adipocyte progenitors. Administration of BMP7 to mice also results in increased energy expenditure. To determine if BMP7 is able to affect the mitochondrial activity of mature brown adipocytes, independent of the differentiation process, we delivered BMP7 to mature brown adipocytes and measured mitochondrial activity. Results: We found that BMP7 increased mitochondrial activity, including fatty acid oxidation and citrate synthase activity, without increasing the mitochondrial number. This was accompanied by an increase in fatty acid uptake and increased protein expression of CPT1 and CD36, which import fatty acids into the mitochondria and the cell, respectively. Importantly, inhibition of either CPT1 or CD36 resulted in a blunting of the mitochondrial activity of BMP7-treated cells. Innovation: These findings uncover a novel pathway regulating mitochondrial activities in mature brown adipocytes by BMP7-mediated fatty acid uptake and oxidation. Conclusion: In conclusion, BMP7 increases mitochondrial activity in mature brown adipocytes via increased fatty acid uptake and oxidation, a process that requires the fatty acid transporters CPT1 and CD36.

AB Objective: Common variants at the 2q36.3-IRS1 locus are associated with insulin resistance (IR), type 2 diabetes (T2D) and coronary artery disease (CAD) in large-scale association studies. We tested the hypothesis that variants at this locus are associated with subclinical atherosclerosis traits.
Methods: We studied 2740 Framingham Heart Study participants (54.9% women; mean age 57.8 years) with measures of coronary artery or abdominal aortic calcium, internal and common carotid intima-media thickness, and ankle-brachial index (ABI). We tested 1) four SNPs previously shown to be associated with IR (rs2972146, rs2943650), T2D (rs2943641) or CAD (rs2943634) and 2) any SNP at 2q36.3-IRS1, for association with subclinical atherosclerosis traits, adjusting for atherosclerosis risk factors. We set type 1 error rate for test 1) as 0.05/5 traits - P < 0.01, and for test 2) as 0.05 divided by the effective number of independent tests, divided by 5 for the number of traits analyzed.
Results: We found no association between the four known SNPs and subclinical atherosclerosis, but identified one SNP (rs10167219, r(2) with rs2943634 = 0.07) at 2q36.3 that was significantly associated with ABI (corrected P = 0.009). However, rs10167219 was not associated with ABI (P = 0.70) in 35,404 participants in a published ABI association study.
Conclusion: Common variants at the 2q36.3-IRS1 locus were not associated with subclinical atherosclerosis traits in this study which was adequately powered to find associations with moderate effect size. Although IR and T2D may be mechanistically linked to CAD via subclinical atherosclerosis, an alternate mechanism for the IR-T2D-CAD associations at 2q36.3-IRS1 must be postulated.

AB Objectives: CD31 identifies a heterogeneous population of cells in the blood, consisting of mature leukocytes and platelets, as well as smaller numbers of endothelial and progenitor cells. Because unfractionated CD31+ blood cells have demonstrated angiogenic properties in vivo, we hypothesized that circulating CD31+ cells would be related to the presence of cardiovascular risk factors in humans.
Methods and results: We studied 1487 participants, free of cardiovascular disease, from the Framingham Offspring Study. Using anti-human CD31 and CD45 antibodies, distinct CD31+/CD45+ leukocyte populations were enumerated in blood samples by FACS analysis. We used linear regression analyses to investigate the relation of each cell phenotype with cardiovascular risk factors. We identified 3 distinct leukocyte populations: CD31 -, CD31 dim, and CD31 bright cells. Using forward/side scatter analyses, CD31 - and CD31 dim cells mapped to lymphoid gates while CD31 bright cells were monocytoid. In multivariable analyses, higher frequency of CD31 bright cells was associated with older age, male sex, HDL cholesterol, and CRP (all P < 0.01). In contrast, CD31 dim was inversely associated with age, male sex, CRP, and smoking (all P < 0.01). Framingham Risk Score was positively associated with CD31 bright frequency (P = 0.002), and negatively associated with CD31 dim frequency (P = 0.020).
Conclusions: CD31+ staining identifies 2 major leukocyte populations, CD31 bright and CD31 dim, which demonstrated significant and opposite associations with cardiovascular risk in humans. Further research is needed to define the biological and potential therapeutic roles of CD31+ subpopulations in vascular disease. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

ID EXPERIENCE
AB Objective To compare the midterm risks of biochemical recurrence (BCR) and salvage radiation therapy (SRT) after laparoscopic (LRP) and open retropubic radical prostatectomy (RRP). Strong evidence that these techniques are comparable to the gold standard' of open RRP is lacking, as most comparative studies are limited by short follow-up or rely on historical controls. Patients and Methods We studied 1000 consecutive patients concurrently treated by either LRP or RRP between 2001 and 2005. LRPs were performed by a single surgeon and RRP by four surgeons. Primary outcomes were BCR and SRT. Survival analysis included relevant clinical and pathological variables. Results Of 844 included patients, 244 underwent LRP and 600 RRP. Clinical and pathological characteristics were similar in both groups. Most patients had Gleason 6 tumours (68%) and pT2 disease (86%). The median follow-up was 6.1 years and median time to recurrence 3.4 years. Overall, BCR occurred in 14% of patients: 13.1% after LRP and 14.7% after RRP. SRT was performed in 10.7% of patients both after LRP and RRP. In uni- and multivariate Cox regression models, surgical technique was not a significant predictor of BCR or SRT. Conclusion Our results suggest that in high-volume centres, LRP provides equivalent oncological control to RRP.

AB Objective To show the underlying variability in peri-operative mortality after radical cystectomy (RC) by analysing failure-to-rescue (FTR) rates, i.e. deaths after complications. Materials and Methods Patients undergoing RC for non-metastatic bladder cancer (BCa) were identified from the Nationwide Inpatient Sample, 1999-2009, resulting in a weighted estimate of 79972 patients. The FTR rates were assessed according to patient and hospital characteristics, as well as complication type. Generalized linear regression analyses were performed. Results Overall, 26740 patients had a complication, corresponding to a FTR rate of 5.5%. Septicaemia (odds ratio [OR]: 13.41, P < 0.001) and cardiac (OR: 3.97, P < 0.001), wound-related (OR: 2.12, P < 0.001), genitourinary (OR: 1.62, P = 0.045) and haematological (OR: 1.78, P = 0.008) complications were associated with FTR. Older age (OR: 1.05, P < 0.001), increasing comorbidities (OR: 1.33, P < 0.001), Medicare (OR: 1.52, P = 0.016), and Medicaid insurance status (OR: 2.10, P = 0.029) were associated with higher odds of FTR. Conversely, increasing hospital volume (OR: 0.992, P = 0.014) reduced the odds of FTR. Conclusions Whereas both patient and hospital characteristics were associated with increased odds of FTR, the occurrence of septicaemia and cardiac complications were the most strongly associated with a higher risk of in-hospital mortality.

AB Tulipa (tulips; Liliaceae) is a genus of geophytes comprising c. 76 species, occurring from southwestern Europe and North Africa to Central Asia. The taxonomy and classification of the genus have been contentious in the past. We investigated the phylogenetic relationships in the genus using DNA sequences from five plastid regions (trnL intron and trnL-trnF spacer, rpl16 intron, rps12-rpl20 intergenic spacer and matK) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA. Amana and Erythronium were used as outgroups. Sequences were obtained from 25 Tulipa taxa representing all major lineages previously identified as distinct and four outgroups (two Amana spp. and two Erythronium spp.). In the combined maximum parsimony analysis, Tulipa was strongly supported as monophyletic and four clearly defined clades in the genus were obtained, although the relationships between them were unclear. In support of previous molecular studies, the results suggest that section Clusianae should be excluded from subgenus Tulipa and accepted at subgeneric rank. Subgenus Eriostemones and subgenus Tulipa (excluding Clusianae) were both strongly supported. Tulipa sprengeri, traditionally placed in subgenus Tulipa, was shown to be a member of Eriostemones. Orithyia, in this study represented by T.uniflora, formed a fourth lineage, also to be treated at subgeneric level. In the Bayesian analysis, the genus Tulipa was strongly supported and the same four lineages (subgenera) were identified. In this case, Orithyia was sister to the rest of the genus (with moderate support) and subgenera Clusianae and Eriostemones together formed a clade with strong support. Original species descriptions and type specimens of as many names as possible were reviewed and, on this basis, a revised checklist with full synonymy, typification and distribution is provided. The status of T.xgesneriana and its synonyms is discussed. All accepted species are classified into the four subgenera supported by our phylogenetic study.(c) 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 172, 280-328.

AB Alzheimer's disease is a neurodegenerative disease that is associated with the abnormal accumulation of amyloid-beta. Much is known about regional brain atrophy in Alzheimer's disease, yet our knowledge about the network nature of Alzheimer's disease-associated amyloid-beta accumulation is limited. We use stepwise connectivity analysis of Pittsburgh Compound B positron emission tomography images to reveal the network properties of amyloid-beta deposits in normal elderly subjects and clinical patients with Alzheimer's disease. We found that amyloid-beta accumulation in the medial temporal lobe is associated with accumulation in cortical regions such as orbitofrontal, lateral temporal and precuneus/posterior cingulate cortices in Alzheimer's disease. In normal subjects, there was a predominant association between amyloid-beta deposits in the hippocampus and the midline prefrontal/orbitofrontal regions, even in those with very low amyloid-beta burden. Moreover, the orbitofrontal cortex, amygdala nucleus and hippocampus exhibit hub properties in the amyloid-beta network that may be critical to understanding the putative spreading mechanisms of Alzheimer's disease pathology in early stages.

AB Invasion of the brain parenchyma by a meningioma classified by histological criteria as World Health Organization (WHO) grade I meningioma, implies that the tumor has greater likelihood of recurrence and a biological behavior similar to the more aggressive WHO grade II meningiomas. It is therefore important to detect microscopic foci of brain invasion during surgery in order to maximize the resection and/or adapt imaging follow-up. In this study, we tested the sensitivity of two handheld confocal imaging devices to detect foci of brain invasion in two types of meningioma mouse models: in a genetically engineered mouse model and in a syngeneic xenograft model. Confocal imaging offered precise images of meningothelial and fibroblastic mouse meningiomas as well as malignant meningiomas, which corresponded exactly to the pathological findings. Imaging showed a sharp definition of the brain-tumor interface and enabled identification of embedded nerves and vessels. Importantly, in both mouse models used in this study, extension of tumor along Virchow-Robin spaces into adjacent brain was detected by imaging. In conclusion, this novel technique, following validation in clinical trials, may open new possibilities for use in operating rooms to influence both decision making during the surgery and planning for additional treatments.

ID VIETNAM-WAR; VETERANS; MORTALITY; EXPOSURE
AB BACKGROUND Agent Orange (AO) exposure (AOe) is a potential risk factor for the development of prostate cancer (PCa). However, it is unknown whether AOe specifically increases the risk of lethal PCa. The objective of this study was to determine the association between AOe and the risk of detecting high-grade PCa (HGPCa) (Gleason score 7) on biopsy in a US Veteran cohort. METHODS Risk factors included clinicodemographic and laboratory data from veterans who were referred for an initial prostate biopsy. Outcomes were defined as the presence versus the absence of PCa, HGPCa, or low-grade PCa (LGPCa) (Gleason score 6) in biopsy specimens. Risk among AOe veterans relative to unexposed veterans was estimated using multivariate logistic regression. Separate models were used to determine whether AOe was associated with an increased risk of PCa, HGPCa, or LGPCa. RESULTS Of 2720 veterans who underwent biopsy, PCa was diagnosed in 896 veterans (32.9%), and 459 veterans (16.9%) had HGPCa. AOe was associated with a 52% increase in the overall risk of detecting PCa (adjusted odds ratio, 1.52; 95% confidence interval, 1.07-2.13). AOe did not confer an increase in the risk of LGPCa (adjusted odds ratio, 1.24; 95% confidence interval, 0.81-1.91), although a 75% increase in the risk of HGPCa was observed (adjusted odds ratio, 1.75; 95% confidence interval, 1.12-2.74). AOe was associated with a 2.1-fold increase (95% confidence interval, 1.22-3.62; P < .01) in the risk of detecting PCa with a Gleason score 8. CONCLUSIONS The current results indicated that an increased risk of PCa associated with AOe is driven by an increased risk of HGPCa in men who undergo an initial prostate biopsy. These findings may aid in improved PCa screening for Vietnam-era veterans. Cancer 2013;119:2399-2404. (c) 2013 American Cancer Society.

AB BACKGROUND The objective was to compare patterns of site-specific cancer mortality in a population of individuals with and without mental illness. METHODS This was a cross-sectional, population-based study using a linked data set comprised of death certificate data for the state of Ohio for the years 2004-2007 and data from the publicly funded mental health system in Ohio. Decedents with mental illness were those identified concomitantly in both data sets. We used age-adjusted standardized mortality ratios (SMRs) in race- and sex-specific person-year strata to estimate excess deaths for each of the anatomic cancer sites. RESULTS Overall, there was excess mortality from cancer associated with having mental illness in all the race/sex strata: SMR, 2.16 (95% CI, 1.85-2.50) for black men; 2.63 (2.31-2.98) for black women; 3.89 (3.61-4.19) for nonblack men; and 3.34 (3.13-3.57) for nonblack women. In all the race/sex strata except for black women, the highest SMR was observed for laryngeal cancer, 3.94 (1.45-8.75) in black men and 6.51 (3.86-10.35) and 6.87 (3.01-13.60) in nonblack men and women, respectively. The next highest SMRs were noted for hepatobiliary cancer and cancer of the urinary tract in all race/sex strata, except for black men. CONCLUSIONS Compared with the general population in Ohio, individuals with mental illness experienced excess mortality from most cancers, possibly explained by a higher prevalence of smoking, substance abuse, and chronic hepatitis B or C infections in individuals with mental illness. Excess mortality could also reflect late-stage diagnosis and receipt of inadequate treatment. Cancer 2013;119:2469-2476. (c) 2013 American Cancer Society.

AB It was investigated whether a standard mouse diet (AIN-76A) supplemented with walnuts reduced the establishment and growth of LNCaP human prostate cancer cells in nude (nu/nu) mice. The walnut-enriched diet reduced the number of tumors and the growth of the LNCaP xenografts; 3 of 16 (18.7%) of the walnut-fed mice developed tumors; conversely, 14 of 32 mice (44.0%) of the control diet-fed animals developed tumors. Similarly, the xenografts in the walnut-fed animals grew more slowly than those in the control diet mice. The final average tumor size in the walnut-diet animals was roughly one-fourth the average size of the prostate tumors in the mice that ate the control diet.

AB Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are severe body image disorders that highly impair individuals in their daily functioning. They are discrete but overlapping nosological entities. In this review, we examine similarities between AN and BDD with regard to clinical, personality and demographic aspects, such as comorbidity, phenomenology, and treatment outcome. The review suggests that the two disorders are highly comorbid, and show similar ages of onset, illness trajectories, and comparable clinical and personality characteristics. However, important differences emerge in their responsiveness to psychosocial and psychopharmacological treatment, which are discussed. Clinical implications of these findings are summarized and directions for future research are delineated, with a focus on how current treatment components from each disorder may inform new interventions for both disorders.

AB Differentiation of naive CD4(+) T cells has been considered to be an irreversible event and, in particular, the plasticity is believed to be completely lost in Th1 subset in vitro after multiple stimulations. However, here we demonstrate that highly polarized myelin oligodendrocyte glycoprotein (MOG)- and herpes simples virus-specific Th1 clones were still capable of producing IL-17 upon superantigen stimulation. Anti-MHC class-II and anti-TCR alpha beta chains partially blocked superantigen-induced IL-17 production. These findings suggest that fully differentiated Th1 cells still have capability to produce cytokines of other Th subsets and production of IL-17 by MOG-specific Th1 cells may have implication in initiation and/or exacerbation of neurological autoimmune diseases.

AB In recent years there has been a growing interest in the possibility of a direct autocrine effect of insulin on the pancreatic beta-cell. Indeed, there have been numerous intriguing articles and several eloquent reviews written on the subject (1-3); however, the concept is still controversial. Although many in vitro experiments, a few transgenic mouse studies, and some human investigations would be supportive of the notion, there exist different insights, other studies, and circumstantial evidence that question the concept. Therefore, the idea of autocrine action of insulin remains a conundrum. Here we outline a series of thoughts, insights, and alternative interpretations of the available experimental evidence. We ask, how convincing are these, and what are the confusing issues? We agree that there is a clear contribution of certain downstream elements in the insulin signaling pathway for beta-cell function and survival, but the question of whether insulin itself is actually the physiologically relevant ligand that triggers this signal transduction remains unsettled.

AB Patients with type 2 diabetes (T2D) often exhibit hyperglucagonemia despite hyperglycemia, implicating defective alpha-cell function. Although endoplasmic reticulum (ER) stress has been suggested to underlie beta-cell dysfunction in T2D, its role in alpha-cell biology remains unclear. X-box binding protein 1 (XBP1) is a transcription factor that plays a crucial role in the unfolded protein response (UPR), and its deficiency in beta-cells has been reported to impair insulin secretion, leading to glucose intolerance. To evaluate the role of XBP1 in alpha-cells, we created complementary in vivo (alpha-cell-specific XBP1 knockout [alpha XBPKO] mice) and in vitro (stable XBP1 knockdown alpha-cell line [alpha XBPKD]) models. The alpha XBPKO mice exhibited glucose intolerance, mild insulin resistance, and an inability to suppress glucagon secretion after glucose stimulation. alpha XBPICD cells exhibited activation of inositol-requiring enzyme 1, an upstream activator of XBP1, leading to phosphorylation of Jun NH2-terminal kinase. Interestingly, insulin treatment of alpha XBPICD cells reduced tyrosine phosphorylation of insulin receptor substrate 1 (IRS1) (py(896)) and phosphorylation of Akt while enhancing serine phosphorylation (pS(307)) of IRS1. Consequently, the alpha XBPKD cells exhibited blunted suppression of glucagon secretion after insulin treatment in the presence of high glucose. Together, these data indicate that XBP1 deficiency in pancreatic alpha-cells induces altered insulin signaling and dysfunctional glucagon secretion.

AB Conversion of one terminally differentiated cell type into another (or transdifferentiation) usually requires the forced expression of key transcription factors. We examined the plasticity of human insulin-producing beta-cells in a model of islet cell aggregate formation. Here, we show that primary human beta-cells can undergo a conversion into glucagon-producing alpha-cells without introduction of any genetic modification. The process occurs within days as revealed by lentivirus-mediated beta-cell lineage tracing. Converted cells are indistinguishable from native alpha-cells based on ultrastructural morphology and maintain their alpha-cell phenotype after transplantation in vivo. Transition of beta-cells into alpha-cells occurs after beta-cell degranulation and is characterized by the presence of beta-cell specific transcription factors Pdx1 and Nkx6.1 in glucagon(+) cells. Finally, we show that lentivirus-mediated knock-down of Arx, a determinant of the alpha-cell lineage, inhibits the conversion. Our findings reveal an unknown plasticity of human adult endocrine cells that can be modulated. This endocrine cell plasticity could have implications for islet development, (patho) physiology, and regeneration.

AB Genome-wide association studies have proven to be highly effective at defining relationships between single nucleotide polymorphisms (SNPs) and clinical phenotypes in complex diseases. Establishing a mechanistic link between a noncoding SNP and the clinical outcome is a significant hurdle in translating associations into biological insight. We demonstrate an approach to assess the functional context of a diabetic nephropathy (DN)-associated SNP located in the promoter region of the gene FRMD3. The approach integrates pathway analyses with transcriptional regulatory pattern-based promoter modeling and allows the identification of a transcriptional framework affected by the DN-associated SNP in the FRMD3 promoter. This framework provides a testable hypothesis for mechanisms of genomic variation and transcriptional regulation in the context of DN. Our model proposes a possible transcriptional link through which the polymorphism in the FRMD3 promoter could influence transcriptional regulation within the bone morphogenetic protein (BMP)-signaling pathway. These findings provide the rationale to interrogate the biological link between FRMD3 and the BMP pathway and serve as an example of functional genomics-based hypothesis generation.

AB Sulphonylureas (SUs) are widely used glucose-lowering agents in type 2 diabetes mellitus (T2DM) with apparent declining efficacy over time. Concerns have been raised from observational retrospective studies on the cardiovascular (CV) safety of SUs but there are few long-term data on CV outcomes from randomized controlled trials (RCTs) involving the use of this class of agents. Most of the observational studies and registry data are conflicting and vary with study population and methodology used for analyses. To address the SU controversy, we reviewed the recently published literature (until end of the year 2011) to evaluate the impact of SUs on CV outcomes in modern, longer-term (>= 72 weeks) RCTs where they were compared in a head-to-head fashion versus an active comparator or were used as part of a treatment strategy. We identified 15 trials and found no report of an increase in the incidence of CV events with the use of SUs. However, the available data are limited, and, most importantly, there was no adequately powered formal head-to-head CV outcome trial designed to address CV safety. Since SUs are still being advocated as second-line therapy added-on to metformin, as one of several classes, and in certain circumstances first-line therapy in T2DM management, definitive data from a dedicated RCT addressing the CV safety question with SUs would be informative. Cardiovascular Outcome Study of Linagliptin versus Glimepiride in Patients with Type 2 Diabetes (CAROLINA) is such a trial, ongoing since November 2010, and is currently the largest head-to-head CV outcome trial that involves a comparison of a SU (glimepiride) with a dipeptidyl peptidase-4 (DPP-4) inhibitor (linagliptin) and will provide a unique perspective with respect to CV outcomes with these two commonly used agents.

AB IGF-I is considered a primary inhibitor of GH secretion. Insulin may also play an important role in regulating GH levels because insulin, like IGF-I, can suppress GH synthesis and release in primary pituitary cell cultures and insulin is negatively correlated with GH levels in vivo. However, understanding the relative contribution insulin and IGF-I exert on controlling GH secretion has been hampered by the fact that circulating insulin and IGF-I are regulated in parallel and insulin (INSR) and IGF-I (IGFIR) receptors are structurally/functionally related and ubiquitously expressed. To evaluate the separate roles of insulin and IGF-I in directly regulating GH secretion, we used the Cre/loxP system to knock down the INSR and IGFIR in primary mouse pituitary cell cultures and found insulin-mediated suppression of GH is independent of the IGFIR. In addition, pharmacological blockade of intracellular signals in both mouse and baboon cultures revealed insulin requires different pathways from IGF-I to exert a maximal inhibitory effect on GH expression/release. In vivo, somatotrope-specific knockout of INSR (SIRKO) or IGFIR (SIGFRKO) increased GH levels. However, comparison of the pattern of GH release, GH expression, somatotrope morphometry, and pituitary explant sensitivity to acute GHRH challenge in lean SIRKO and SIGFRKO mice strongly suggests the primary role of insulin in vivo is to suppress GH release, whereas IGF-I serves to regulate GH synthesis. Finally, SIRKO and/or SIGFRKO could not prevent high-fat, diet-induced suppression of pituitary GH expression, indicating other factors/tissues are involved in the decline of GH observed with weight gain.

ID RHEUMATOID-ARTHRITIS; ALIGNMENT; FUSION
AB Previous studies have reported that the alignments of the occipital-cervical and subaxial spine were closely interrelated in asymptomatic individuals; however, none have focused on a population with atlantoaxial dislocation.
From 2007 to 2011, 298 patients with atlantoaxial dislocation and atlas occipitalization were studied. Angles formed between Occiput-C2 and C2-C7 were measured. The relationship between the alignment of the occipital-cervical junction and the subaxial cervical spine was evaluated.
The range of values for the angles measured was as followed: the Occiput-C2 angles were -35.2A degrees to 44.8A degrees, and the C2-C7 angles were -17.4A degrees to 77.8A degrees. Statistically significant negative correlations were observed between the Occiput-C2 and C2-C7 angles.
Anterior dislocations of the atlas are associated with diminished lordosis or even kyphosis of the occipital-cervical junction, and result in compensatory hyperlordosis of the subaxial cervical spine, collectively presenting as a "swan neck" deformity. Atlantoaxial dislocation may influence the global cervical alignment.

AB Background:
Safety net hospitals (SNH) have, on average, experienced declining financial margins and faced an elevated risk of closure over the past decade. Despite these challenges, not all SNHs are weakening and some are prospering. These higher-performing SNHs provide substantial care to safety net populations and produce sustainable financial returns.
Purpose:
Drawing on the alternative structural positioning and resource-based views, we explore strategic management as a source of performance differences across SNHs.
Methodology/Approach:
We employ a mixed-method design, blending quantitative and qualitative data and analysis. We measure financial performance using hospital operating margin and quantitatively evaluate its relationship with a limited set of well-defined structural positions. We further evaluate these structures and also explore the internal resources of SNHs based on nine in-depth case studies developed from site visits and extensive interviews.
Findings:
Quantitative results suggest that structural positions alone are not related to performance. Comparative case studies suggest that higher-performing SNH differ in four respects: (1) coordinating patient flow across the care continuum, (2) engaging in partnerships with other providers, (3) managing scope of services, and (4) investing in human capital. On the basis of these findings, we propose a model of strategic action related to systems thinking the ability to see wholes and interrelationships rather than individual parts alone.
Practice Implications:
Our exploratory findings suggest the need to move beyond generic strategies alone and acknowledge the importance of underlying managerial capabilities. Specifically, our findings suggest that effective strategy is a function of both the internal resources (e.g., managers' systems-thinking capability) and structural positions (e.g., partnerships) of organizations. From this perspective, framing resources and positioning as distinct alternatives misses the nuances of how strategic advantage is actually achieved.

AB Nitric oxide is a pronatriuretic and prodiuretic factor. The highest renal NO synthase (NOS) activity is found in the inner medullary collecting duct. The collecting duct (CD) is the site of daily fine-tune regulation of sodium balance, and led us to hypothesize that a CD-specific deletion of NOS1 would result in an impaired ability to excrete a sodium load leading to a salt-sensitive blood pressure phenotype. We bred AQP2-CRE mice with NOS1 floxed mice to produce flox control and CD-specific NOS1 knockout (CDNOS1KO) littermates. CDs from CDNOS1KO mice produced 75% less nitrite, and urinary nitrite+nitrate (NOx) excretion was significantly blunted in the knockout genotype. When challenged with high dietary sodium, CDNOS1KO mice showed significantly reduced urine output, sodium, chloride, and NOx excretion, and increased mean arterial pressure relative to flox control mice. In humans, urinary NOx is a newly identified biomarker for the progression of hypertension. These findings reveal that NOS1 in the CD is critical in the regulation of fluid-electrolyte balance, and this new genetic model of CD NOS1 gene deletion will be a valuable tool to study salt-dependent blood pressure mechanisms.

AB Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF) is gaining momentum as a tool for bacterial identification in the clinical microbiology laboratory. Compared with conventional methods, this technology can more readily and conveniently identify a wide range of organisms. Here, we report the findings from a multicenter study to evaluate the Vitek MS v2.0 system (bioMerieux, Inc.) for the identification of aerobic Gram-positive bacteria. A total of 1,146 unique isolates, representing 13 genera and 42 species, were analyzed, and results were compared to those obtained by nucleic acid sequence-based identification as the reference method. For 1,063 of 1,146 isolates (92.8%), the Vitek MS provided a single identification that was accurate to the species level. For an additional 31 isolates (2.7%), multiple possible identifications were provided, all correct at the genus level. Mixed-genus or single-choice incorrect identifications were provided for 18 isolates (1.6%). Although no identification was obtained for 33 isolates (2.9%), there was no specific bacterial species for which the Vitek MS consistently failed to provide identification. In a subset of 463 isolates representing commonly encountered important pathogens, 95% were accurately identified to the species level and there were no misidentifications. Also, in all but one instance, the Vitek MS correctly differentiated Streptococcus pneumoniae from other viridans group streptococci.

AB The optimal management of fungal infections is correlated with timely organism identification. Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry (MS) is revolutionizing the identification of yeasts isolated from clinical specimens. We present a multicenter study assessing the performance of the Vitek MS system (bioMerieux) in identifying medically important yeasts. A collection of 852 isolates was tested, including 20 Candida species (626 isolates, including 58 C. albicans, 62 C. glabrata, and 53 C. krusei isolates), 35 Cryptococcus neoformans isolates, and 191 other clinically relevant yeast isolates; in total, 31 different species were evaluated. Isolates were directly applied to a target plate, followed by a formic acid overlay. Mass spectra were acquired using the Vitek MS system and were analyzed using the Vitek MS v2.0 database. The gold standard for identification was sequence analysis of the D2 region of the 26S rRNA gene. In total, 823 isolates (96.6%) were identified to the genus level and 819 isolates (96.1%) were identified to the species level. Twenty-four isolates (2.8%) were not identified, and five isolates (0.6%) were misidentified. Misidentified isolates included one isolate of C. albicans (n = 58) identified as Candida dubliniensis, one isolate of Candida parapsilosis (n = 73) identified as Candida pelliculosa, and three isolates of Geotrichum klebahnii (n = 6) identified as Geotrichum candidum. The identification of clinically relevant yeasts using MS is superior to the phenotypic identification systems currently employed in clinical microbiology laboratories.

AB Psychiatric and neurodegenerative disorders, including intellectual disability, autism spectrum disorders (ASD), schizophrenia (SZ), and Alzheimer's disease, pose an immense burden to society. Symptoms of these disorders become manifest at different stages of life: early childhood, adolescence, and late adulthood, respectively. Progress has been made in recent years toward understanding the genetic substrates, cellular mechanisms, brain circuits, and endophenotypes of these disorders. Multiple lines of evidence implicate excitatory and inhibitory synaptic circuits in the cortex and hippocampus as key cellular substrates of pathogenesis in these disorders. Excitatory/inhibitory balance - modulated largely by dopamine - critically regulates cortical network function, neural network activity (i.e. gamma oscillations) and behaviors associated with psychiatric disorders. Understanding the molecular underpinnings of synaptic pathology and neuronal network activity may thus provide essential insight into the pathogenesis of these disorders and can reveal novel drug targets to treat them. Here, we discuss recent genetic, neuropathological, and molecular studies that implicate alterations in excitatory and inhibitory synaptic circuits in the pathogenesis of psychiatric disorders across the lifespan.

AB Object. Electrocorticography (ECoG) is a powerful tool for presurgical functional mapping. Power increase in the high gamma band has been observed from ECoG electrodes on the surface of the sensory motor cortex during the execution of body movements. In this study the authors aim to validate the clinical usage of high gamma activity in presurgical mapping by comparing ECoG mapping with traditional direct electrical cortical stimulation (ECS) and functional MRI (fMRI) mapping.
Methods. Seventeen patients with epilepsy participated in an ECoG motor mapping experiment. The patients executed a 5-minute hand/tongue movement task while the ECoG signal was recorded. All 17 patients also underwent extraoperative ECS mapping to localize the motor cortex. Eight patients also participated in a presurgical fMRI study. The high gamma activity on ECoG was modeled using the general linear model (GLM), and the regions showing significant gamma power increase during the task condition compared with the rest condition were localized. The maps derived from GLM-based ECoG mapping, ECS, and fMRI were then compared.
Results. High gamma activity in the motor cortex can be reliably modulated by motor tasks. Localization of the motor regions achieved with GLM-based ECoG mapping was consistent with the localization determined by ECS. The maps also appeared to be highly localized compared with the fMRI activations. Using the ECS findings as the reference, GLM-based ECoG mapping showed a significantly higher sensitivity than fMRI (66.7% for ECoG, 52.6% for fMRI, p < 0.05), while the specificity was high for both techniques (> 97%). If the current-spreading effect in ECS is accounted for, ECoG mapping may produce maps almost identical to those produced by ECS mapping (100% sensitivity and 99.5% specificity).
Conclusions. General linear model based ECoG mapping showed a superior performance compared to traditional ECS and fMRI mapping in terms of efficiency and accuracy. Using this method, motor functions can be reliably mapped in less than 5 minutes.

AB Amyloid PET imaging is a novel diagnostic test that can detect in living humans one of the two defining pathologic lesions of Alzheimer disease, amyloid-beta deposition in the brain. The Amyloid Imaging Task Force of the Alzheimer's Association and Society for Nuclear Medicine and Molecular Imaging previously published appropriate use criteria for amyloid PET as an important tool for increasing the certainty of a diagnosis of Alzheimer disease in specific patient populations. Here, the task force further clarifies and expands 3 topics discussed in the original paper: first, defining dementia experts and their use of proper documentation to demonstrate the medical necessity of an amyloid PET scan; second, identifying a specific subset of individuals with mild cognitive impairment for whom an amyloid PET scan is appropriate; and finally, developing educational programs to increase awareness of the amyloid PET appropriate use criteria and providing instructions on how this test should be used in the clinical decision-making process.

TI Calcium channels in rat horizontal cells regulate feedback inhibition of

AB Horizontal cells send inhibitory feedback to photoreceptors, helping form antagonistic receptive fields in the retina, but the neurotransmitter and the mechanisms underlying this signalling are not known. Since the proteins responsible for conventional Ca2+-dependent release of GABAergic synaptic vesicles are present in mammalian horizontal cells, we investigated this conventional mechanism as the means by which horizontal cells inhibit photoreceptors. Using Ca2+ imaging in rat retinal slices, we confirm that horizontal cell depolarization with kainate inhibits and horizontal cell hyperpolarization with NBQX disinhibits the Ca2+ signals produced by pH-sensitive activation of voltage-gated calcium channels (Ca channels) in photoreceptors. We show that while 100 mu M Co2+ reduces photoreceptor Ca2+ signals, it disinhibits them at 10 mu M, an effect reminiscent of earlier studies where low [Co2+] eliminated feedback. The low [Co2+] disinhibition is pH sensitive. We localized L-, N- and P/Q-type Ca channels in rat horizontal cells, and showed that both the N-type Ca channel blocker omega-conotoxin GVIA and the P/Q-type Ca channel blocker omega-agatoxin IVA increased Ca2+ signals in photoreceptors in a pH-sensitive manner. Pronounced actions of GABAergic agents on feedback signals to photoreceptors were observed, and are pH sensitive, but are inconsistent with direct inhibition by GABA of photoreceptor [Ca2+]. Patch-clamp studies revealed that GABA activates a conductance having high bicarbonate permeability in isolated horizontal cells, suggesting that the commonality of pH sensitivity throughout the results could arise from a GABA autofeedback action in horizontal cells. This could change cleft pH with concomitant inhibitory influences on photoreceptor Ca channels.

AB Background: Pathology of the shoulder contributes significantly to the increasing burden of musculoskeletal disease. Currently, there exists high variability in the nature and quality of shoulder care, and outcomes and cost reporting are not uniform. Value-based practice aims to simultaneously maximize outcomes and minimize costs for given disease processes.
Methods: The current state of the shoulder care literature was examined with regards to cost and outcomes data, initiatives in streamlining care delivery, and evidence-based practice improvements. This was synthesized with value-based care theory to propose new avenues to improve shoulder care in the future.
Conclusion: The treatment of shoulder disorders is ideal for the value-based model but has been slow to adopt its principles thus far. We can begin to advance value-based practices through (1) the universal reporting of outcomes and costs, (2) integrating shoulder care across provider specialties, and (3) critically analyzing data to formulate best practices.

fungoides; photon brachytherapy; radiation; skin-directed therapy
ID MYCOSIS-FUNGOIDES; CANCER
AB Background: The use of many of the standard skin-directed mycosis fungoides (MF) therapies on facial skin may be limited by site-specific increased risks of side effects, excessive inflammation, and ocular toxicity.
Objective: Our study aimed to describe the levels of erythema, scale, and induration of facial lesions in MF before and after low-dose high-dose-rate surface applicator brachytherapy and to examine the overall clinical response to brachytherapy.
Methods: A total of 23 facial MF lesions in 10 patients were treated with high-dose-rate brachytherapy doses of 4 Gy per session for a total of 2 fractions at our multidisciplinary cutaneous oncology clinic between August 17, 2009, and March 12, 2012.
Results: In all 23 lesions, dramatic clinical improvement was observed. Patients were followed up for a median of 6.3 months. No recurrences were reported in the follow-up period.
Limitations: Long-term follow-up is lacking. Reassessment of all included patients at annual intervals for a period of at least 5 years is the authors' goal.
Conclusion: Low-dose high-dose-rate brachytherapy using custom-made surface molds is a highly efficacious therapy in the treatment of facial lesions in MF.

AB Complex communities of bacteria, fungi, and viruses thrive on our skin. The composition of these communities depends on skin characteristics, such as sebaceous gland concentration, moisture content, and temperature, as well as on host genetics and exogenous environmental factors. Recent metagenomic studies have uncovered a surprising diversity within these ecosystems and have fostered a new view of commensal organisms as playing a much larger role in immune modulation and epithelial health than previously expected. Understanding microbe-host interactions and discovering the factors that drive microbial colonization will help us understand the pathogenesis of skin diseases and develop new promicrobial and antimicrobial therapeutics.

AB Background An enduring challenge in personalized medicine lies in selecting the right drug for each individual patient. While testing of drugs on patients in large trials is the only way to assess their clinical efficacy and toxicity, we dramatically lack resources to test the hundreds of drugs currently under development. Therefore the use of preclinical model systems has been intensively investigated as this approach enables response to hundreds of drugs to be tested in multiple cell lines in parallel.
Methods Two large-scale pharmacogenomic studies recently screened multiple anticancer drugs on over 1000 cell lines. We propose to combine these datasets to build and robustly validate genomic predictors of drug response. We compared five different approaches for building predictors of increasing complexity. We assessed their performance in cross-validation and in two large validation sets, one containing the same cell lines present in the training set and another dataset composed of cell lines that have never been used during the training phase.
Results Sixteen drugs were found in common between the datasets. We were able to validate multivariate predictors for three out of the 16 tested drugs, namely irinotecan, PD-0325901, and PLX4720. Moreover, we observed that response to 17-AAG, an inhibitor of Hsp90, could be efficiently predicted by the expression level of a single gene, NQO1.
Conclusion These results suggest that genomic predictors could be robustly validated for specific drugs. If successfully validated in patients' tumor cells, and subsequently in clinical trials, they could act as companion tests for the corresponding drugs and play an important role in personalized medicine.

AB Context Failure to notify patients of test results is common even when electronic health records (EHRs) are used to report results to practitioners. We sought to understand the broad range of social and technical factors that affect test result management in an integrated EHR-based health system.
Methods Between June and November 2010, we conducted a cross-sectional, web-based survey of all primary care practitioners (PCPs) within the Department of Veterans Affairs nationwide. Survey development was guided by a socio-technical model describing multiple inter-related dimensions of EHR use.
Findings Of 5001 PCPs invited, 2590 (51.8%) responded. 55.5% believed that the EHRs did not have convenient features for notifying patients of test results. Over a third (37.9%) reported having staff support needed for notifying patients of test results. Many relied on the patient's next visit to notify them for normal (46.1%) and abnormal results (20.1%). Only 45.7% reported receiving adequate training on using the EHR notification system and 35.1% reported having an assigned contact for technical assistance with the EHR; most received help from colleagues (60.4%). A majority (85.6%) stayed after hours or came in on weekends to address notifications; less than a third reported receiving protected time (30.1%). PCPs strongly endorsed several new features to improve test result management, including better tracking and visualization of result notifications.
Conclusions Despite an advanced EHR, both social and technical challenges exist in ensuring notification of test results to practitioners and patients. Current EHR technology requires significant improvement in order to avoid similar challenges elsewhere.

AB Functional magnetic resonance imaging (fMRI) studies have identified consistent age-related changes during various cognitive tasks, such that older individuals display more positive and less negative task-related activity than young adults. Recently, evidence shows that chronic physical exercise may alter aging-related changes in brain activity; however, the effect of exercise has not been studied for the neural substrates of language function. Additionally, the potential mechanisms by which aging alters neural recruitment remain understudied. To address these points, the present study enrolled elderly adults who were either sedentary or physically active to characterize the neural correlates of language function during semantic fluency between these groups in comparison to a young adult sample. Participants underwent fMRI during semantic fluency and transcranial magnetic stimulation to collect the ipsilateral silent period, a measure of interhemispheric inhibition. Results indicated that sedentary older adults displayed reductions in negative task-related activity compared to the active old group in areas of the attention network. Longer interhemispheric inhibition was associated with more negative task-related activity in the right and left posterior perisylvian cortex, suggesting that sedentary aging may result in losses in task facilitatory cortical inhibition. However, these losses may be mitigated by regular engagement in physical exercise.

AB Background: Despite level 1 evidence in support of carotid endarterectomy vs medical therapy in selected asymptomatic patients, an alternative posture is that optimal medical therapy (OMT) has not been adequately studied and that such OMT has reduced stroke risk in asymptomatic patients to levels wherein carotid endarterectomy is no longer justified. The goal of this study was to determine the natural history of patients with asymptomatic moderate (50%-69%) carotid artery stenosis (AMCAS) in a contemporary cohort as a function of their associated medical therapy.
Methods: Patients with AMCAS determined by duplex ultrasound (DUS) from 2005-2006 were identified in our hospital database. Patients were included in the cohort if they had at least one additional DUS during the 6-year follow-up interval. Patient characteristics including medication history and lipid levels were collected. Patients were considered to have OMT if they were on aspirin and a statin with a low-density lipoprotein level that was always <100 mg/dL. Study end points included progression of carotid disease by DUS to severe stenosis (70%-100%), development of ipsilateral neurologic symptoms (INS) such as stroke or transient ischemic attack, and death.
Results: There were 900 carotid arteries in 794 patients in the study cohort. The average age was 72.5 years, 77.2% had hypertension, 59.6% had coronary artery disease, and 87.1% were on a statin throughout the study. The low-density lipoprotein cholesterol level was always normal (<100 mg/dL) in 37.8% and accordingly, 241 (30.3%) had OMT as defined above. The 5-year actuarial survival was 81.9% +/- 1.3% with no advantage seen with OMT. Multivariate analysis of survival showed statins were protective (hazard ratio [HR], 0.50; confidence interval [CI], 0.34-0.73; P = .0004). The 5-year freedom from plaque progression was 61.2% +/- 2.1% with no benefit from OMT vs the control group. Multivariate predictors of plaque progression were chronic kidney disease (HR, 2.1; CI, 1.2-3.7; P = .009), aspirin use (HR, 1.9; CI, 1.2-3.0; P = .01), and the use of calcium channel blockers (HR, 1.4; CI, 1.1-1.8; P = .007). There were 90 (11.3%) patients who developed INS during follow-up (58% of these were strokes), and the 5-year freedom from INS was 88.4% 6 1.5%. Multivariate predictors of INS were diabetes (HR, 2.3; CI, 1.5-3.6; P = .0002) and warfarin use (HR, 1.9; CI, 1.2-2.9; P = .009); while statin use (HR, 0.37; CI, 0.22-0.65; P = .0005) was protective against symptom development.
Conclusions: At the 5-year of follow-up, OMT failed to prevent carotid disease progression or development of ipsilateral symptoms in 45% of patients with AMCAS.

AB Interleukin-10 functions as a general immunosuppressive cytokine, which also negatively regulates inflammatory responses through complex mechanisms. Recent studies suggested that IL-10 may also inhibit fibrosis in various diseased models. However, the role of IL-10 in renal fibrosis has not been demonstrated. Here, we investigated the effects of IL-10 in the development of renal tubulointerstitial fibrosis by creating the unilateral ureteral obstruction (UUO) model in IL-10 knockout (-/-) mice. We performed sham or unilateral ureteral obstruction surgery in 8-week-old IL-10 -/- male mice and age and sex-matched wild type littermates. Mice were killed at 7 days or 14 days post surgery and renal tissues were obtained for RNA, protein, and immunohistochemical analysis. Our results found IL-10 deficiency resulted in enhanced renal fibrosis demonstrated by more severe tubular injury and collagen deposition and higher expression of pro-fibrotic genes (including alpha-SMA, MMP-2, fibronectin, FSP-1 and vimentin). Our results also found IL-10-/- UUO mice developed more severe renal inflammation with a significant increase in inflammatory cells infiltration, and upregulation of inflammatory chemokines (MCP-1 and RANTES), and cytokines (TNF-alpha, IL-6, IL-8, and M-CSF). Further study revealed that enhanced renal inflammation and fibrosis was associated with significantly increased activation of both TGF-beta/Smad3 and NF-kappa B signaling pathways. In summary, our study provides the direct evidence that IL-10 is an endogenous cytokine that has a key role in protecting against development of renal inflammation and fibrosis. Enhancement of IL-10 expression could be a potential anti-fibrosis therapy for patients with chronic kidney diseases.

AB Objectives/Hypothesis Repair of the transected facial nerve has traditionally been accomplished with microsurgical neurorrhaphy; however, fibrin adhesive coaptation (FAC) of peripheral nerves has become increasingly popular over the past decade. We compared functional recovery following suture neurorrhaphy to FAC in a rodent facial nerve model. Study Design Prospective, randomized animal study. Methods Sixteen rats underwent transection and repair of the facial nerve proximal to the pes anserinus. Eight animals underwent epineurial suture (ES) neurorrhaphy, and eight underwent repair with fibrin adhesive (FA). Surgical times were documented for all procedures. Whisking function was analyzed on a weekly basis for both groups across 15 weeks of recovery. Results Rats experienced whisking recovery consistent in time course and degree with prior studies of rodent facial nerve transection and repair. There were no significant differences in whisking amplitude, velocity, or acceleration between suture and FA groups. However, the neurorrhaphy time with FA was 70% shorter than for ES (P < 0.05). Conclusion Although we found no difference in whisking recovery between suture and FA repair of the main trunk of the rat facial nerve, the significantly shorter operative time for FA repair makes this technique an attractive option. The relative advantages of both techniques are discussed.

AB Background and Objectives Radiofrequency (RF) energy exposure is a popular non-invasive method for generating heat within cutaneous and subcutaneous tissues. Subcutaneous fat consists of fine collagen fibrous septa meshed with clusters of adipocytes having distinct structural, electrical and thermal properties that affect the distribution and deposition of RF energy. The objectives of this work are to (i) determine the electric and thermal effects of the fibrous septa in the RF heating; (ii) investigate the RF heating of individual fat lobules enclosed by fibrous septa; and, (iii) discuss the clinical implications. Methods and Results We used the finite element method to model the two-dimensional, time-dependent, electro-thermal response of a three-layer tissue (skin, subcutaneous fat, and muscle). We considered two different configurations of subcutaneous fat tissue: a homogenous layer of fat only and a honeycomb-like layer of fat with septa. Architecture of the fibrous septa was anatomically accurate, constructed from sagittal images from human micro-MRI. For a large electrode applied to the skin surface, results show that the absorbed electric power density is greater in some septa than in the surrounding fat lobules, favoring the flux of electric current density. Fibers aligned parallel to the electric field have higher electric flux and, consequently, absorb more power. Heat transfer from the septa occurs over time during and after RF energy delivery. There is a greater temperature rise in fat with fibrous septa. Conclusions The presence of septa affects the local distribution of the static electric field, facilitates the flux of electric current and enhances the bulk electric power absorption of the subcutaneous fat layer. Fibrous septa aligned with the local electric field have higher absorbed power density than septa oriented perpendicular to the electric field. Individual fat lobules gain heat instantly by local power absorption and, eventually, by diffusion from the surrounding septa. Lasers Surg. Med. 45:326-338, 2013. (c) 2013 Wiley Periodicals, Inc.

AB We have developed a sensitive, specific, rapid and low cost picoliter microsphere-based platform for bioanalyte detection and quantification. In this method, a biological sample, biosensing microspheres, and fluorescently labeled detection (secondary) antibodies are co-encapsulated to capture the analyte (here: human anti-tetanus immunoglobulin G) on the surface of the microsphere in microfluidic pL-sized droplets. The absorption of the analyte and detecting antibodies on the microsphere concentrate the fluorescent signal in correlation with analyte concentration. Using our platform and commercially available antibodies, we were able to quantify anti-tetanus antibodies in human serum. In comparison to standard bulk immunosorbent assays, the microfluidic droplet platform presented here reduces the reagent volume by four orders of magnitude, while fast reagent mixing reduces the detection time from hours to minutes. We consider this platform to be a major leap forward in the miniaturization of immunosorbent assays and to provide a rapid and low cost tool for global point-of-care.

AB The reduction in the expression of glucose-responsive insulin gene transcription factor MafA accompanies the development of beta-cell dysfunction under oxidative stress/diabetic milieu. Humans with type 2 diabetes have reduced MafA expression, and thus preventing this reduction could overcome beta-cell dysfunction and diabetes. We previously showed that p38 MAPK, but not glycogen synthase kinase 3 (GSK3), is a major regulator of MafA degradation under oxidative stress. Here, we examined the mechanisms of this degradation and whether preventing MafA degradation under oxidative stress will overcome beta-cell dysfunction. We show that under oxidative and nonoxidative conditions p38 MAPK directly binds to MafA and triggers MafA degradation via ubiquitin proteasomal pathway. However, unlike nonoxidative conditions, MafA degradation under oxidative stress depended on p38 MAPK-mediated phosphorylation at threonine (T) 134, and not T57. Furthermore the expression of alanine (A) 134-MafA, but not A57-MafA, reduced the oxidative stress-mediated loss of glucose-stimulated insulin secretion, which was independent of p38 MAPK action on protein kinase D, a regulator of insulin secretion. Interestingly, the expression of proteasomal activator PA28 gamma that degrades GSK3-phosphorylated (including T57) MafA was reduced under oxidative stress, explaining the dominance of p38 MAPK over the GSK3 pathway in regulating MafA stability under oxidative stress. These results identify two distinct pathways mediating p38 MAPK-dependent MafA degradation under oxidative and non-oxidative conditions and show that inhibiting MafA degradation under oxidative stress ameliorates beta-cell dysfunction and could lead to novel therapies for diabetes.

AB Obsessive-compulsive disorder (OCD) is a common, debilitating neuropsychiatric illness with complex genetic etiology. The International OCD Foundation Genetics Collaborative (IOCDF-GC) is a multi-national collaboration established to discover the genetic variation predisposing to OCD. A set of individuals affected with DSM-IV OCD, a subset of their parents, and unselected controls, were genotyped with several different Illumina SNP microarrays. After extensive data cleaning, 1465 cases, 5557 ancestry-matched controls and 400 complete trios remained, with a common set of 469 410 autosomal and 9657 X-chromosome single nucleotide polymorphisms (SNPs). Ancestry-stratified case-control association analyses were conducted for three genetically-defined subpopulations and combined in two meta-analyses, with and without the trio-based analysis. In the case-control analysis, the lowest two P-values were located within DLGAP1 (P = 2.49 x 10(-6) and P = 3.44 x 10(-6)), a member of the neuronal postsynaptic density complex. In the trio analysis, rs6131295, near BTBD3, exceeded the genome-wide significance threshold with a P-value = 3.84 x 10(-8). However, when trios were meta-analyzed with the case-control samples, the P-value for this variant was 3.62 x 10(-5), losing genome-wide significance. Although no SNPs were identified to be associated with OCD at a genome-wide significant level in the combined trio-case-control sample, a significant enrichment of methylation QTLs (P < 0.001) and frontal lobe expression quantitative trait loci (eQTLs) (P = 0.001) was observed within the top-ranked SNPs (P < 0.01) from the trio-case-control analysis, suggesting these top signals may have a broad role in gene expression in the brain, and possibly in the etiology of OCD.

AB Glioblastoma (GBM) comprises 51% of all gliomas and is the most malignant form of brain tumors with a median survival of 18-21 months. Standard-of-care treatment includes maximal surgical resection of the tumor mass in combination with radiation and chemotherapy. However, as the poor survival rate indicates, these treatments have not been effective in preventing disease progression. Cellular immunotherapy is currently being explored as therapeutic approach to treat malignant brain tumors. In this review, we discuss advances in active, passive, and vaccine-based immunotherapeutic strategies for gliomas both at the bench and in the clinic.

AB The continued spread of HIV underscores the need to interrupt transmission. One attractive strategy, in the absence of an effective vaccine, is a topical microbicide, but the need for application around the time of sexual intercourse leads to poor patient compliance. Intravaginal (IVAG) application of CD4 aptamer-siRNA chimeras (CD4-AsiCs) targeting the HIV coreceptor CCR5, gag, and vif protected humanized mice from sexual transmission. In non-dividing cells and tissue, RNAi-mediated gene knockdown lasts for several weeks, providing an opportunity for infrequent dosing not temporally linked to sexual intercourse, when compliance is challenging. Here, we investigate the durability of gene knockdown and viral inhibition, protection afforded by CCR5 or HIV gene knockdown on their own, and effectiveness of CD4-AsiCs formulated in a gel in polarized human cervicovaginal explants and in humanized mice. CD4-AsiC-mediated gene knockdown persisted for several weeks. Cell-specific gene knockdown and protection were comparable in a hydroxyethylcellulose gel formulation. CD4-AsiCs against CCR5 or gag/vif performed as well as a cocktail in humanized mice. Transmission was completely blocked by CCR5 CD4-AsiCs applied 2 days before challenge. Significant, but incomplete, protection also occurred when exposure was delayed for 4 or 6 days. CD4-AsiCs targeting gag/vif provided some protection when administered only after exposure. These data suggest that CD4-AsiCs are a promising approach for developing an HIV microbicide.

AB Postmortem studies of synapses in human brain are problematic because of the axial resolution limit of light microscopy and the difficulty in preserving and analyzing ultrastructure with electron microscopy (EM). Array tomography (AT) overcomes these problems by embedding autopsy tissue in resin and cutting ribbons of ultrathin serial sections. Ribbons are imaged with immunofluorescence, allowing high-throughput imaging of tens of thousands of synapses to assess synapse density and protein composition. The protocol takes similar to 3 d per case, excluding image analysis, which is done at the end of the study. Parallel processing for transmission electron microscopy (TEM) using a protocol modified to preserve the structure in human samples allows complementary ultrastructural studies. Incorporation of AT and TEM into brain banking is a potent way of phenotyping synapses in well-characterized clinical cohorts in order to develop clinicopathological correlations at the synapse level. This will be important for research in neurodegenerative disease, developmental disease and psychiatric illness.

AB Wide variation exists in the use of inferior vena cava filters for the treatment of venous thromboembolism, possibly because of a deficit of evidence on the efficacy of these devices, and a lack of consensus on their use. Future guidelines should be evidence-based and account for the development of novel anticoagulants.

RECTAL-CANCER; RELATIVE BIOLOGICAL EFFECTIVENESS; RANDOMIZED
CONTROLLED-TRIAL; CURRENT CLINICAL-EVIDENCE; RISK PROSTATE-CANCER
AB The use of charged particle therapy to control tumours non-invasively offers advantages over conventional radiotherapy. Protons and heavy ions deposit energy far more selectively than X-rays, allowing a higher local control of the tumour, a lower probability of damage to healthy tissue, low risk of complications and the chance for a rapid recovery after therapy. Charged particles are also useful for treating tumours located in areas that surround tissues that are radiosensitive and in anatomical sites where surgical access is limited. Current trial outcomes indicate that accelerated ions can potentially replace surgery for radical cancer treatments, which might be beneficial as the success of surgical cancer treatments are largely dependent on the expertise and experience of the surgeon and the location of the tumour. However, to date, only a small number of controlled randomized clinical trials have made comparisons between particle therapy and X-rays. Therefore, although the potential advantages are clear and supported by data, the cost: benefit ratio remains controversial. Research in medical physics and radiobiology is focusing on reducing the costs and increasing the benefits of this treatment.

AB Genome-wide association studies have identified many variants that each affects multiple traits, particularly across autoimmune diseases, cancers and neuropsychiatric disorders, suggesting that pleiotropic effects on human complex traits may be widespread. However, systematic detection of such effects is challenging and requires new methodologies and frameworks for interpreting cross-phenotype results. In this Review, we discuss the evidence for pleiotropy in contemporary genetic mapping studies, new and established analytical approaches to identifying pleiotropic effects, sources of spurious cross-phenotype effects and study design considerations. We also outline the molecular and clinical implications of such findings and discuss future directions of research.

AB The cervical spine can frequently become involved in patients with rheumatologic disorders, as a result of either the rheumatologic disease itself or age-associated degenerative processes that can also occur in the rest of the population. Awareness of the increased risk of cervical spine manifestations in patients with rheumatologic disorders enables early recognition and initiation of the appropriate treatment regimen. For example, patients with rheumatoid arthritis (RA) often have spinal instability which, if left untreated, can lead to neurological deficits. Biologic agents are effective in slowing the progression of the skeletal abnormality as well as for treating the RA, and this approach is often sufficient. However, early surgical intervention is recommended for patients with RA who develop neurologic deficits, as conservative approaches have limited effectiveness in this group. Spinal stability should be the primary surgical objective. For patients with ankylosing spondylitis, cervical spine surgery might be required either for fracture repair or to correct severe kyphosis. Understanding each condition's specific cervical spine manifestation and its natural history can help to clarify the appropriate indications for and timing of surgery to maximize patients' outcomes and limit complications.

AB A substantial proportion of the broadly neutralizing antibodies (bnAbs) identified in certain HIV-infected donors recognize glycan-dependent epitopes on HIV-1 gp120. Here we elucidate how the bnAb PGT 135 binds its Asn332 glycan-dependent epitope from its 3.1-angstrom crystal structure with gp120, CD4 and Fab 17b. PGT 135 interacts with glycans at Asn332, Asn392 and Asn386, using long CDR loops H1 and H3 to penetrate the glycan shield and access the gp120 protein surface. EM reveals that PGT 135 can accommodate the conformational and chemical diversity of gp120 glycans by altering its angle of engagement. Combined structural studies of PGT 135, PGT 128 and 2G12 show that this Asn332-dependent antigenic region is highly accessible and much more extensive than initially appreciated, which allows for multiple binding modes and varied angles of approach; thereby it represents a supersite of vulnerability for antibody neutralization.

AB HIV-1 uses a diverse N-linked-glycan shield to evade recognition by antibody. Select human antibodies, such as the clonally related PG9 and PG16, recognize glycopeptide epitopes in the HIV-1 V1-V2 region and penetrate this shield, but their ability to accommodate diverse glycans is unclear. Here we report the structure of antibody PG16 bound to a scaffolded V1-V2, showing an epitope comprising both high mannose-type and complex-type N-linked glycans. We combined structure, NMR and mutagenesis analyses to characterize glycan recognition by PG9 and PG16. Three PG16-specific residues, arginine, serine and histidine (RSH), were critical for binding sialic acid on complex-type glycans, and introduction of these residues into PG9 produced a chimeric antibody with enhanced HIV-1 neutralization. Although HIV-1-glycan diversity facilitates evasion, antibody somatic diversity can overcome this and can provide clues to guide the design of modified antibodies with enhanced neutralization.

AB Despite growing appreciation of the importance of long noncoding RNAs (lncRNAs) in normal physiology and disease, our knowledge of cancer-related lncRNAs remains limited. By repurposing microarray probes, we constructed expression profiles of 10,207 lncRNA genes in approximately 1,300 tumors over four different cancer types. Through integrative analysis of the lncRNA expression profiles with clinical outcome and somatic copy-number alterations, we identified lncRNAs that are associated with cancer subtypes and clinical prognosis and predicted those that are potential drivers of cancer progression. We validated our predictions by experimentally confirming prostate cancer cell growth dependence on two newly identified lncRNAs. Our analysis provides a resource of clinically relevant lncRNAs for the development of lncRNA biomarkers and the identification of lncRNA therapeutic targets. It also demonstrates the power of integrating publically available genomic data sets and clinical information for discovering disease-associated lncRNAs.

AB Background We developed and evaluated a novel system for guiding radiofrequency catheter ablation therapy of ventricular tachycardia. This guidance system employs an inverse solution guidance algorithm (ISGA) using a single equivalent moving dipole (SEMD) localization method. The method and system were evaluated in both a saline tank phantom model and in vivo animal (swine) experiments.
Methods A catheter with two platinum electrodes spaced 3 mm apart was used as the dipole source in the phantom study. A 40-Hz sinusoidal signal was applied to the electrode pair. In the animal study, four to eight electrodes were sutured onto the right ventricle. These electrodes were connected to a stimulus generator delivering 1-ms duration pacing pulses. Signals were recorded from 64 electrodes, located either on the inner surface of the saline tank or on the body surface of the pig, and then processed by the ISGA to localize the physical or bioelectrical SEMD.
Results In the phantom studies, the guidance algorithm was used to advance a catheter tip to the location of the source dipole. The distance from the final position of the catheter tip to the position of the target dipole was 2.22 +/- 0.78 mm in real space and 1.38 +/- 0.78 mm in image space (computational space). The ISGA successfully tracked the locations of electrodes sutured on the ventricular myocardium and the movement of an endocardial catheter placed in the animal's right ventricle.
Conclusion In conclusion, we successfully demonstrated the feasibility of using an SEMD inverse algorithm to guide a cardiac ablation catheter.

AB Introduction: This study focuses on the implementation of modulated modularity clustering (MMC) a new cluster algorithm for the identification of molecular signatures of preeclampsia and intrauterine growth restriction (IUGR), and the identification of affected microRNAs
Methods: Eighty-six human placentas from normal (40), growth-restricted (27), and preeclamptic (19) term pregnancies were profiled using Illumina Human-6 Beadarrays. MMC was utilized to generate modules based on similarities in placental transcriptome. Gene Set Enrichment Analysis (GSEA) was used to predict affected microRNAs. Expression levels of these candidate microRNAs were investigated in seventy-one human term placentas as follows: control (29); IUGR (26); and preeclampsia (16).
Results: MMC identified two modules, one representing IUGR placentas and one representing preeclamptic placentas. 326 differentially expressed genes in the module representing IUGR and 889 differentially expressed genes in a module representing preeclampsia were identified. Functional analysis of molecular signatures associated with IUGR identified P13K/AKT, mTOR, p70S6K, apoptosis and IGF-1 signaling as being affected. Analysis of variance of GSEA-predicted microRNAs indicated that miR-194 was significantly down-regulated both in preeclampsia (p = 0.0001) and IUGR (p = 0.0304), and miR-149 was significantly down-regulated in preeclampsia (p = 0.0168).
Discussion: Implementation of MMC, allowed identification of genes disregulated in IUGR and preeclampsia. The reliability of MMC was validated by comparing to previous linear modeling analysis of preeclamptic placentas.
Conclusion: MMC allowed the elucidation of a molecular signature associated with preeclampsia and a subset of IUGR samples. This allowed the identification of genes, pathways, and microRNAs affected in these diseases. (C) 2013 Elsevier Ltd. All rights reserved.

AB Objectives: Automated external defibrillators (AEDs) are lifesaving, but little is known about where they are located or how to find them. We sought to locate AEDs in high employment areas of Philadelphia and characterize the process of door-to-door surveying to identify these devices.
Methods: Block groups representing approximately the top 3rd of total primary jobs in Philadelphia were identified using the US Census Local Employment Dynamics database. All buildings within these block groups were surveyed during regular working hours over six weeks during July-August 2011. Buildings were characterized as publically accessible or inaccessible. For accessible buildings, address, location type, and AED presence were collected. Total devices, location description and prior use were gathered in locations with AEDs. Process information (total people contacted, survey duration) was collected for all buildings.
Results: Of 1420 buildings in 17 block groups, 949 (67%) were accessible, but most 834 (88%) did not have an AED. 283 AEDs were reported in 115 buildings (12%). 81 (29%) were validated through visualization and 68 (24%) through photo because employees often refused access. In buildings with AEDs, several employees (median 2; range 1-8) were contacted to ascertain information, which required several minutes (mean 4; range 1-55).
Conclusions: Door-to-door surveying is a feasible, but time-consuming method for identifying AEDs in high employment areas. Few buildings reported having AEDs and few permitted visualization, which raises concerns about AED access. To improve cardiac arrest outcomes, efforts are needed to improve the availability of AEDs, awareness of their location and access to them. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

AB The lateral aspect of the hip is composed of a complex array of osseous and soft tissue structures. Both common and uncommon clinical entities are encountered in the lateral hip. This article briefly introduces fundamental imaging anatomy and the functional roles of different osseous and soft tissue structures in the lateral aspect of the hip, followed by a discussion of relevant imaging findings of lateral hip pathology. Greater trochanteric pain syndrome is frequently encountered in patients with lateral hip pain and encompasses a spectrum of soft tissue abnormalities including trochanteric and subgluteal bursitis, and tendinopathy or tears of the gluteal tendons. In addition, different types of injuries to the gluteal myotendinous unit and injuries to the indirect head of the rectus femoris, proximal iliotibial band, and the lateral joint capsular ligaments can present with lateral hip pain.

AB The management of prostate cancer is complicated by the multitude of treatment options, the lack of proven superiority of one modality of management, and the presence of physician bias. Care at a multidisciplinary prostate cancer clinic offers patients the relative convenience of consultation with physicians of multiple specialties within the confines of a single visit and appears to serve as a venue in which patients can be counseled regarding the risks and benefits of available therapies in an open and interactive environment. Physician bias may be minimized in such an environment, and patient satisfaction rates are high. Available data suggest that low-risk patients who are seen at a multidisciplinary prostate cancer clinic appear to select active surveillance in greater proportion. However, relatively few studies have investigated the other added value that multidisciplinary clinics provide to the patient or health care system, and therefore, additional studies assessing the impact of multidisciplinary care in the management of patients with prostate cancer are needed.

AB Men receiving radiation for prostate cancer frequently want to know what steps they can take to optimize their chance of cure and reduce their risk of side effects. A variety of modifiable behaviors, medications, and complementary alternative medicine interventions have been investigated in this regard. In this review, we summarize data on tobacco use, exercise, statins and aspirin, and vitamins. There is limited randomized data supporting any of the interventions and additional studies are needed before clinicians can confidently inform their patients regarding what steps to take to improve their outcomes.

AB The National Comprehensive Cancer Network guidelines currently endorse salvage local therapy as a reasonable alternative to observation or androgen-deprivation therapy for select men with a biopsy-proven local recurrence after definitive radiation for prostate cancer. Patients being considered for salvage therapy should have had localized disease at presentation, a prostate-specific antigen < 10 at recurrence, a life expectancy >10 years at recurrence, and a negative metastatic workup. In this systematic review, we synthesize the current literature describing the oncologic efficacy and toxicity profile of salvage brachytherapy, prostatectomy, cryotherapy, and high-intensity focused ultrasound. We found 5-year biochemical control rates to be similar across treatments, in the range of 52%-56%, although patient selection and definition of failure was variable. Toxicity profiles were also distinct between local salvage modalities. Semin Radiat Oncol 23:222-234 (C) 2013 Elsevier Inc. All rights reserved.

AB OBJECTIVE To examine urology trainees' views about the quality and current practices of end-of-life care and to explore strategies for improving integration and quality of care.
METHODS We conducted semi-structured interviews with 20 trainees from 4 institutions in different regions of the United States. Open-ended questions allowed participants to express themselves independently, and follow-up discussions explored their perception of current end-of-life practices, as well as avenues for future integration and improvement. We analyzed transcripts using a multistage, cutting-and-sorting technique in an inductive approach based on grounded theory analysis.
RESULTS Clinicians agreed that their patients do not currently receive ideal care and were interested in joining a team geared towards improving care at the end of life. They expressed a preference for a multidisciplinary team, although the precise role each wanted to play within the team varied. Better identification of depression, pain, and patient-centered goals to allow value-congruent care were high in priorities for improvement. Trainees cited the lack of an educational curriculum on end-of-life care as a barrier to improving care and expressed a desire for formal education on this topic.
CONCLUSION Urology trainees believe that end-of-life care can be improved and are interested in participating as part of a multidisciplinary team to better care for these individuals. There was consensus that end-of-life care should be formally taught to all intern and resident physicians and care at the end of life should be integrated to pursue value-congruent care for each patient.

DE Biomarker combination; covariate adjustment; AUC; covariate

ID OPERATING CHARACTERISTIC CURVE; REGRESSION; ACCURACY; MARKERS; AREA
AB Rational and Objectives: Receiver operating characteristic (ROC) analysis is often used to find the optimal combination of biomarkers. When the subject level covariates affect the magnitude and/or accuracy of the biomarkers, the combination rule should take into account of the covariate adjustment. The authors propose two new biomarker combination methods that make use of the covariate information.
Materials and Methods: The first method is to maximize the area under the covariate-adjusted ROC curve (AAUC). To overborne the limitations of the AAUC measure, the authors further proposed the area under covariate-standardized ROC curve (SAUC), which is an extension of the covariate-specific ROC curve. With a series of simulation studies, the proposed optimal AAUC and SAUC methods are compared with the optimal AUC method that ignores the covariates. The biomarker combination methods are illustrated by an example from Alzheimer's disease research.
Results: The simulation results indicate that the optimal AAUC combination performs well in the current study population. The optimal SAUC method is flexible to choose any reference populations, and allows the results to be generalized to different populations.
Conclusions: The proposed optimal AAUC and SAUC approaches successfully address the covariate adjustment problem in estimating the optimal marker combination. The optimal SAUC method is preferred-for practical use, because the biomarker combination rule can be easily evaluated for different population of interest.

AB Individualized therapies are popular current concepts in oncology and first steps towards stratified medicine have now been taken in neurooncology through implementation of stratified therapeutic approaches. Knowledge about the molecular basis of brain tumors has expanded greatly in recent years and a few molecular alterations are studied routinely because of their clinical relevance. However, no single targeted agent has yet been fully approved for the treatment of glial brain tumors. In this review, we argue that multidisciplinary and integrated approaches are essential for translational research and the development of new treatments for patients with malignant gliomas, and we present a conceptual framework in which to place the components of such an interdisciplinary approach. We believe that this ambitious goal can be best realized through strong cooperation of brain tumor centers with local hospitals and physicians; such an approach enables close dialogue between expert subspecialty clinicians and local therapists to consider all aspects of this increasingly complex set of diseases.

AB Objectives: Limited data exist on outcomes of older adults receiving psychotherapy for depression in real-world settings. Acceptance and Commitment Therapy for depression (ACT-D) offers potential utility for older individuals who may experience issues of loss, reduced control, and other life changes. The present article examines and compares outcomes of older and younger Veterans receiving ACT-D nationally in the U.S. Department of Veterans Affairs health care system.
Method: Patient outcomes were assessed using the Beck Depression Inventory-Second Edition and the World Health Organization Quality of Life-BREF. Therapeutic alliance was assessed using the Working Alliance Inventory-Short Revised.
Results: Six hundred fifty-five Veterans aged 18-64 and 76 Veterans aged 65+ received ACT-D. Seventy-eight percent of older and 67% of younger patients completed all sessions or finished early. Mean depression scores declined from 28.4 (SD = 11.4) to 17.5 (SD = 12.0) in the older group and 30.3 (SD = 10.6) to 19.1 (SD = 14.3) in the younger group. Within-group effect sizes were d = .95 and d = 1.06 for the two age groups, respectively. Quality of life and therapeutic alliance also increased during treatment.
Conclusion: The findings suggest that ACT-D is an effective and acceptable treatment for older Veterans treated in routine clinical settings, including those with high levels of depression.

AB Background:
Accumulation of -amyloid protein (A) and tau protein is the main feature of Alzheimer disease neuropathogenesis. Anesthetic isoflurane, but not desflurane, may increase A levels in vitro and in animals. Therefore, we set out to determine the effects of isoflurane and desflurane on cerebrospinal fluid (CSF) levels of A and tau in humans.
Methods:
The participants were assigned into spinal anesthesia (N = 35), spinal plus desflurane anesthesia (N = 33), or spinal plus isoflurane anesthesia (N = 38) group by randomization using computer-generated lists. Pre- and postoperative human CSF samples were obtained through an inserted spinal catheter. The levels of A (A40 and A42) and total tau in the CSF were determined.
Results:
Here, we show that isoflurane, but not desflurane, was associated with an increase in human CSF A40 levels (from 10.90 to 12.41 ng/ml) 24 h after the surgery under anesthesia compared to spinal anesthesia (from 11.59 to 11.08 ng/ml), P = 0.022. Desflurane, but not isoflurane, was associated with a decrease in A42 levels 2 h after the surgery under anesthesia (from 0.39 to 0.35 ng/ml) compared to spinal anesthesia (from 0.43 to 0.44 ng/ml), P = 0.006. Isoflurane and desflurane did not significantly affect the tau levels in human CSF.
Conclusions:
These studies have established a system to study the effects of anesthetics on human biomarkers associated with Alzheimer disease and cognitive dysfunction. These findings have suggested that isoflurane and desflurane may have different effects on human CSF A levels.

AB Background:
Lung derecruitment is common during general anesthesia. Mechanical ventilation with physiological tidal volumes could magnify derecruitment, and produce lung dysfunction and inflammation. The authors used positron emission tomography to study the process of derecruitment in normal lungs ventilated for 16 h and the corresponding changes in regional lung perfusion and inflammation.
Methods:
Six anesthetized supine sheep were ventilated with V-T = 8 ml/kg and positive end-expiratory pressure = 0. Transmission scans were performed at 2-h intervals to assess regional aeration. Emission scans were acquired at baseline and after 16 h for the following tracers: (1) F-18-fluorodeoxyglucose to evaluate lung inflammation and (2) (NN)-N-13 to calculate regional perfusion and shunt fraction.
Results:
Gas fraction decreased from baseline to 16 h in dorsal (0.31 +/- 0.13 to 0.14 +/- 0.12, P < 0.01), but not in ventral regions (0.61 +/- 0.03 to 0.63 +/- 0.07, P = nonsignificant), with time constants of 1.5-44.6 h. Although the vertical distribution of relative perfusion did not change from baseline to 16 h, shunt increased in dorsal regions (0.34 +/- 0.23 to 0.63 +/- 0.35, P < 0.01). The average pulmonary net F-18-fluorodeoxyglucose uptake rate in six regions of interest along the ventral-dorsal direction increased from 3.4 +/- 1.4 at baseline to 4.1 +/- 1.510(-3)/min after 16 h (P < 0.01), and the corresponding average regions of interest F-18-fluorodeoxyglucose phosphorylation rate increased from 2.0 +/- 0.2 to 2.5 +/- 0.210(-2)/min (P < 0.01).
Conclusions:
When normal lungs are mechanically ventilated without positive end-expiratory pressure, loss of aeration occurs continuously for several hours and is preferentially localized to dorsal regions. Progressive lung derecruitment was associated with increased regional shunt, implying an insufficient hypoxic pulmonary vasoconstriction. The increased pulmonary net uptake and phosphorylation rates of F-18-fluorodeoxyglucose suggest an incipient inflammation in these initially normal lungs.

AB Objective
Evidence suggests that chronic low-grade inflammation and oxidative stress are related to cardiovascular disease (CVD) and mortality.
Approach and Results
We examined 11 established and novel biomarkers representing inflammation and oxidative stress (C-reactive protein, fibrinogen, interleukin-6, intercellular adhesion molecule-1, lipoprotein-associated phospholipase-A2 [mass and activity], monocyte chemoattractant protein-1, myeloperoxidase, CD40 ligand, P-selectin, and tumor necrosis factor receptor II [TNFRII]) in relation to incident major CVD and mortality in the community. We studied 3035 participants (mean age, 61 +/- 9 years; 53% women). During follow-up (median, 8.9 years), 253 participants experienced a CVD event and 343 died. C-reactive protein (hazard ratio [HR] reported per SD ln-transformed biomarker, 1.18; 95% confidence interval [CI], 1.02-1.35; nominal P=0.02) and TNFRII (HR, 1.15; 95% CI, 1.01-1.32; nominal P=0.04) were retained in multivariable-adjusted models for major CVD, but were not significant after adjustment for multiple testing. The biomarkers related to mortality were TNFRII (HR, 1.33; 95% CI, 1.19-1.49; P<0.0001), ICAM-1 (HR, 1.24; 95% CI, 1.12-1.37; P<0.0001), and interleukin-6 (HR, 1.25; 95% CI, 1.12-1.39; P<0.0001). The addition of these markers to the model, including traditional risk factors, increased discrimination and reclassification for risk of death (P<0.0001), but not for CVD.
Conclusions
Of 11 inflammatory biomarkers tumor necrosis factor receptor II was related to cardiovascular disease and mortality in the Framingham Heart Study. The combination of TNFRII with C-reactive protein in relation to CVD and with interleukin-6 to mortality increased the predictive ability in addition to CVD risk factors for total mortality but not for incident CVD.

AB Background: Early identification of depressed individuals at high risk for treatment resistance could be helpful in selecting optimal setting and intensity of care. At present, validated tools to facilitate this risk stratification are rarely used in psychiatric practice.
Methods: Data were drawn from the first two treatment levels of a multicenter antidepressant effectiveness study in major depressive disorder, the STAR*D (Sequenced Treatment Alternatives to Relieve Depression) cohort. This cohort was divided into training, testing, and validation subsets. Only clinical or sociodemographic variables available by or readily amenable to self-report were considered. Multivariate models were developed to discriminate individuals reaching remission with a first or second pharmacological treatment trial from those not reaching remission despite two trials.
Results: A logistic regression model achieved an area under the receiver operating characteristic curve exceeding .71 in training, testing, and validation cohorts and maintained good calibration across cohorts. Performance of three alternative models with machine learning approaches-a naive Bayes classifier and a support vector machine, and a random forest model-was less consistent. Similar performance was observed between more and less severe depression, men and women, and primary versus specialty care sites. A web-based calculator was developed that implements this tool and provides graphical estimates of risk.
Conclusion: Risk for treatment resistance among outpatients with major depressive disorder can be estimated with a simple model incorporating baseline sociodemographic and clinical features. Future studies should examine the performance of this model in other clinical populations and its utility in treatment selection or clinical trial design.

AB Autologous hematopoietic cell transplantation (auto-HCT) is performed to treat relapsed and recurrent malignant disorders and as part of initial therapy for selected malignancies. This study evaluated changes in use, techniques, and survival in a population-based cohort of 68,404 patients who underwent first auto-HCT in a US or Canadian center between 1994 and 2005 and were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). The mean annual number of auto-HCTs performed was highest during 1996-1999 (6948), and decreased subsequently 2000-2003 (4783), owing mainly to fewer auto-HCTs done to treat breast cancer. However, the mean annual number of auto-HCTs increased from 5278 annually in 1994-1995 to 5459 annually in 2004-2005, reflecting increased use for multiple myeloma, non-Hodgkin lymphoma, and Hodgkin lymphoma. Despite an increase in the median recipient age from 44 to 53 years, there has been a significant improvement in overall survival (OS) from 1994 to 2005 in patients with chemotherapy-sensitive relapsed non-Hodgkin lymphoma (day +100 OS, from 85% to 96%; 1-year OS, from 68% to 80%; P < .001) and chemotherapy-sensitive multiple myeloma (day +100 OS, from 96% to 98%; 1-year OS, from 83% to 92%; P < .001). This improvement in OS was most pronounced in middle-aged (>40 years) and older (>60 years) individuals. (C) 2013 American Society for Blood and Marrow Transplantation.

AB Multiple myeloma is the second most common hematologic malignancy affecting terminally differentiated plasma cells. Although high-dose chemotherapy and autologous stem cell transplantation have improved survival in younger patients, the natural history of multiple myeloma has been changed with the availability of six new agents approved in the past 10 years (thalidomide, bortezomib, lenalidomide, liposomal doxorubicin, carfilzomib, and pomalidomide). Despite this significant improvement in the overall outcome, multiple myeloma remains incurable in the majority of patients, prompting a continued search for additional therapeutic options. Extensive molecular and genomic characterization of multiple myeloma cells in their bone marrow milieu, which affects myeloma cell growth and survival, has provided a number of novel drugable targets and pathways. Perturbation of protein catabolism at multiple levels has become an important target in multiple myeloma. Similarly, improvements in monoclonal antibody generation and vaccine development, along with identification of a number of cell surface and cellular targets, have led to the development of various strategies, including antibodies and antibody-drug conjugates that are under investigation preclinically and in early clinical studies. We propose that eventually, molecularly informed multiagent combination therapies will be required to eliminate the multiple myeloma cell clone for long-term disease control. (C)2013 AACR.

TI PD-L1 Expression Is Characteristic of a Subset of Aggressive B-cell

AB Purpose: Programmed cell death ligand 1 (PD-L1) is an immunomodulatory molecule expressed by antigen-presenting cells and select tumors that engages receptors on T cells to inhibit T-cell immunity. Immunotherapies targeting the PD-1/PD-L1 pathway have shown durable antitumor effects in a subset of patients with solid tumors. PD-L1 can be expressed by Reed-Sternberg cells comprising classical Hodgkin lymphoma (CHL) and by malignant B cells comprising EBV-positive posttransplant lymphoproliferative disorders (PTLD). We sought to determine whether the expression of PD-L1 represents a general strategy of immune evasion among aggressive B-cell lymphomas and virus-and immunodeficiency-associated tumors.
Experimental Design: Using novel antibodies and formalin-fixed, paraffin-embedded (FFPE) tissue biopsies, we examined 237 primary tumors for expression of PD-L1.
Results: Robust PD-L1 protein expression was found in the majority of nodular sclerosis and mixed cellularity CHL, primary mediastinal large B-cell lymphoma, T-cell/histiocyte-rich B-cell lymphoma, EBV-positive and -negative PTLD, and EBV-associated diffuse large B-cell lymphoma (DLBCL), plasmablastic lymphoma, extranodal NK/T-cell lymphoma, nasopharyngeal carcinoma, and HHV8-associated primary effusion lymphoma. Within these tumors, PD-L1 was highly expressed by malignant cells and tumor-infiltrating macrophages. In contrast, neither the malignant nor the nonmalignant cells comprising nodular lymphocyte-predominant Hodgkin lymphoma, DLBCL-not otherwise specified, Burkitt lymphoma, and HHV8-associated Kaposi sarcoma expressed detectable PD-L1.
Conclusion: Certain aggressive B-cell lymphomas and virus-and immunodeficiency-associated malignancies associated with an ineffective T-cell immune response express PD-L1 on tumor cells and infiltrating macrophages. These results identify a group of neoplasms that should be considered for PD-1/PD-L1-directed therapies, and validate methods to detect PD-L1 in FFPE tissue biopsies. (C)2013 AACR.

Hepatic Dysfunction: A National Cancer Institute Organ Dysfunction
Working Group Study
SO CLINICAL CANCER RESEARCH
LA English
DT Article
ID ORAL PAZOPANIB; INHIBITOR; TRIAL
AB Purpose: Pazopanib is a potent, multitargeted receptor tyrosine kinase inhibitor; however, there is limited information regarding the effects of liver function on pazopanib metabolism and pharmacokinetics. The objective of this study was to establish the maximum-tolerated dose (MTD) and pharmacokinetic profile of pazopanib in patients with varying degrees of hepatic dysfunction.
Experimental Design: Patients with any solid tumors or lymphoma were stratified into four groups based on the degree of hepatic dysfunction according to the National Cancer Institute Organ Dysfunction Working Group (NCI-ODWG) criteria. Pazopanib was given orally once a day on a 21-day cycle. A modified 3+3 design was used.
Results: Ninety-eight patients were enrolled. Patients in the mild group tolerated 800 mg per day. The moderate and severe groups tolerated 200 mg per day. Pharmacokinetic data in the mild group were similar to the data in the normal group. Comparison of the median C-max and area under the curve [AUC((0-24))] in the moderate or severe groups at 200 mg per day to the values in the normal and mild groups at 800 mg per day indicated less than dose-proportional systemic exposures in patients with moderate and severe hepatic impairment. This suggests that the lower maximum-tolerated dose in the moderate and severe group is not due to a decrease in drug clearance or alteration in the proportion of metabolites.
Conclusions: In patients with mild liver dysfunction, pazopanib is well tolerated at the Food and Drug Administration (FDA)-approved dose of 800 mg per day. Patients with moderate and severe liver dysfunction tolerated 200 mg per day. Clin Cancer Res; 19(13); 3631-9. (C)2013 AACR.

AB Purpose: A multiple myeloma vaccine has been developed whereby patient-derived tumor cells are fused with autologous dendritic cells, creating a hybridoma that stimulates a broad antitumor response. We report on the results of a phase II trial in which patients underwent vaccination following autologous stem cell transplantation (ASCT) to target minimal residual disease.
Experimental Design: Twenty-four patients received serial vaccinations with dendritic cell/myeloma fusion cells following posttransplant hematopoietic recovery. A second cohort of 12 patients received a pretransplant vaccine followed by posttransplant vaccinations. Dendritic cells generated from adherent mononuclear cells cultured with granulocyte macrophage colony-stimulating factor, interleukin-4, and TNF-alpha were fused with autologous bone marrow-derived myeloma fusion cells using polyethylene glycol. Fusion cells were quantified by determining the percentage of cells that coexpress dendritic cell and myeloma fusion antigens.
Results: The posttransplant period was associated with reduction in general measures of cellular immunity; however, an increase in CD4 and CD8(+) myeloma-specific T cells was observed after ASCT that was significantly expanded following posttransplant vaccination. Seventy-eight percent of patients achieved a best response of complete response (CR)+very good partial response (VGPR) and 47% achieved a CR/near CR (nCR). Remarkably, 24% of patients who achieved a partial response following transplant were converted to CR/nCR after vaccination and at more than 3 months posttransplant, consistent with a vaccine-mediated effect on residual disease.
Conclusions: The posttransplant period for patients with multiple myeloma provides a unique platform for cellular immunotherapy in which vaccination with dendritic cell/myeloma fusion fusions resulted in the marked expansion of myeloma-specific T cells and cytoreduction of minimal residual disease.

AB Purpose: A phase I study was conducted with the primary objective of determining the maximum tolerated dose (MTD) of AUY922 in patients with advanced solid tumors. Secondary objectives included characterization of the safety, pharmacokinetic, and pharmacodynamic profiles.
Patients and Methods: Patients with advanced solid tumors received 1-hour i.v. infusions of AUY922 once a week in a 28-day cycle. An adaptive Bayesian logistic regression model that employed observed dose-limiting toxicities (DLT) in the first treatment cycle was used to guide dose-escalation decisions, with the established MTD to be used in phase II studies.
Results: One hundred and one patients were enrolled and explored at doses in the range of 2 to 70mg/m(2). DLTs occurred in 8 patients (22-70 mg/m(2)) and included diarrhea, asthenia/fatigue, anorexia, atrial flutter, and visual symptoms. At 70 mg/m(2), the AUY922 concentration achieved was consistent with active concentrations in a range of xenograft models. There was evidence of target inhibition in peripheral blood mononuclear cells (HSP70 induction) and tumor (client protein depletion and reduction of metabolic activity by F-18-FDG PET). The recommended phase II dose (RP2D) of 70mg/m(2) was proposed on the basis of toxicity and pharmacokinetic and pharmacodynamic profiles.
Conclusions: At the RP2D of 70 mg/m(2), AUY922 exhibited acceptable tolerability, and phase II single-agent and combination studies have been initiated in patients with HER2-positive breast, gastric, and non-small cell lung cancers. Clin Cancer Res; 19(13); 3671-80. (C)2013 AACR.

AB The aim of this study was to evaluate the objective value of neuropsychological evaluation (NPE) through reduction in Emergency Room (ER) visits and hospitalizations. Retrospective analysis examined trends in ER visits and hospitalizations in 440 U.S. veterans who completed NPE between the years of 2003 and 2010. Within-subjects comparisons showed significant decreases in incidence of hospitalization and length of hospitalization in the year after evaluation compared to the year prior. Mean number of hospitalizations declined from 0.31 (SD = 0.64) pre-NPE to 0.22 (SD = 0.59) post-NPE; there were a total of 41 fewer hospitalizations in the year following NPE. Mean length of hospitalization decreased from 1.9 days (SD = 5.6) pre-NPE to 1.06 days (SD = 3.9) post-NPE; there were a total of 368 fewer days of hospitalization post-NPE. This reduction was not attributable to age or time. Incidence of ER visits also decreased from pre-NPE (M = 0.74, SD = 1.3) to post-evaluation (M = 0.69, SD = 1.3), though this was not significant. These findings provide preliminary evidence of the clinical and potential economic value of neuropsychological services within a medical setting. Follow-up studies should examine individual and exam-specific factors that may contribute to reduced utilization.

AB Objective:
To determine whether potential exposure to natural light via windows or to more pleasing views through windows affects outcomes or costs among critically ill patients.
Design:
Retrospective cohort study.
Setting:
An academic hospital in Philadelphia, PA.
Patients:
Six thousand one hundred thirty-eight patients admitted to a 24-bed medical ICU and 6,631 patients admitted to a 24-bed surgical ICU from July 1, 2006, to June 30, 2010.
Interventions:
Assignment to medical ICU rooms with vs. without windows and to surgical ICU rooms with natural vs. industrial views based on bed availability.
Measurements and Main Results:
In primary analyses adjusting for patient characteristics, medical ICU patients admitted to rooms with (n = 4,093) versus without (n = 2,243) windows did not differ in rates of ICU (p = 0.25) or in-hospital (p = 0.94) mortality, ICU readmissions (p = 0.37), or delirium (p = 0.56). Surgical ICU patients admitted to rooms with natural (n = 3,072) versus industrial (n = 3,588) views experienced slightly shorter ICU lengths of stay and slightly lower variable costs. Instrumental variable analyses based on initial bed assignment and exposure time did not show any differences in any outcomes in either the medical ICU or surgical ICU cohorts, and none of the differences noted in primary analyses remained statistically significant when adjusting for multiple comparisons. In a prespecified subgroup analysis among patients with ICU length of stay greater than 72 hours, MICU windows were associated with reduced ICU (p = 0.02) and hospital mortality (p = 0.04); these results did not meet criteria for significance after adjustment for multiple comparisons.
Conclusions:
ICU rooms with windows or natural views do not improve outcomes or reduce costs of in-hospital care for general populations of medical and surgical ICU patients. Future work is needed to determine whether targeting light from windows directly toward patients influences outcomes and to explore these effects in patients at high risk for adverse outcomes.

AB A trial-level meta-analysis was conducted to determine the relative risk (RR) of venous thromboembolic events (VTEs) associated with approved vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TIC]). Eligible studies included randomized phase 2 and 3 trials comparing arms with and without a Food and Drug Administration-approved VEGFR TKI (sunitinib, sorafenib, pazopanib, vandetanib, and axitinib). Statistical analyses calculated the RR and 95% confidence intervals (CI), using random-effects or fixed-effects models based on heterogeneity. A total of 7441 patients from 9 phase III trials and 8 phase II trials were selected. The RR of all grade and high-grade VTEs for the TKI vs. no TKI arms was 1.10 (95% CI 0.73-1.66, p = 0.64) and 0.85 (95% CI: 0.58-1.25, p = 0.41), respectively. No difference in risk was found based on tumor type, age and trial design. The majority of trials exhibited high quality per Jadad scoring and no heterogeneity or publication bias was found.

ID NEPHROPATHY
AB Lithium salts are the mainstay of treatment of bipolar disorder. However, the therapeutic index of lithium is narrow, and severe side effects may be seen. Nephrotoxicity is the most important side effect, which may progress to chronic renal failure. In this pictorial essay, we present ultrasonography, computed tomography, and magnetic resonance imaging findings of renal toxicity secondary to chronic lithium use. We believe that imaging could be extremely helpful for the evaluation of renal toxicity and may even detect preclinical stages of renal parenchymal injury. A combination of different imaging modalities may help clarify findings detected on one modality.

AB Background: Androgen-deprivation therapy (ADT) for prostate cancer (PCa) may be associated with cardiovascular disease and diabetes. Some data suggest that men with certain conditions may be more susceptible to developing cardiovascular disease than others.
Objective: To assess whether the risk of myocardial infarction (MI) or diabetes during ADT is modified by specific baseline comorbidities.
Design, setting, and participants: We conducted a population-based observational study of 185 106 US men >= 66 yr of age diagnosed with local/regional PCa from 1992 to 2007. We assessed comorbidities monthly over the follow-up period.
Outcome measurements and statistical analysis: Cox proportional hazards models with time-varying variables assessing incident diabetes or MI.
Results and limitations: A total of 49.9% of the men received ADT during follow-up. Among men with no comorbidities, ADT was associated with an increase in the adjusted hazard of MI (adjusted hazard ratio [AHR]: 1.09; 95% confidence interval [CI], 1.02-1.16) and diabetes (AHR: 1.33; 95% CI, 1.27-1.39). Risks of MI and diabetes were similarly increased among men with and without specific comorbid illnesses (p > 0.10 for all interactions, with one exception). Previous MI, congestive heart failure, peripheral arterial disease, stroke, hypertension, chronic obstructive pulmonary disease, and renal disease were associated with new MI and diabetes, and obesity and rheumatologic disease were also associated with diabetes. Limitations include the observational study design, reliance on administrative data to ascertain outcomes, and lack of information on risk factors such as smoking and family history.
Conclusions: Traditional risk factors for MI and diabetes were also associated with developing these conditions during ADT but did not significantly modify the risk attributable to ADT. Strategies to screen and prevent diabetes and cardiovascular disease in men with PCa should be similar to the strategies recommended for the general population.

AB Background Constitutive activation of nuclear factor B (NF-B) is associated with poor prognosis. Irinotecan demonstrates single-agent activity in head and neck cancer but activates NF-B, promoting cell survival and resistance. Bortezomib is a proteasome inhibitor that inactivates NF-B. Patients and Methods We performed a randomized phase II trial of bortezomib on days 1, 4, 8, and 11 and irinotecan on days 1 and 8 of each 21-day cycle or single-agent bortezomib on days 1, 4, 8, and 11 on a 21-day cycle. The addition of irinotecan to bortezomib was allowed in patients who progressed on bortezomib alone. Results The response rate of bortezomib and irinotecan was 13%. One patient had a partial response to bortezomib alone (response rate 3%). No responses were seen in patients with addition of irinotecan at time of progression on bortezomib. Conclusions The bortezomib-based regimens evaluated in this study have minimal activity in recurrent or metastatic head and neck cancer. Head Neck, 2013

AB The international orthopaedic community aims to achieve the best possible outcome for patient care by constantly modifying surgical techniques and expanding the surgeon's knowledge. These efforts require proper reflection within a setting that necessitates a higher quality standard for global orthopaedic publication. Furthermore, these techniques demand that surgeons acquire information at a rapid rate while enforcing higher standards in research performance. An international consensus exists on how to perform research and what rules should be considered when publishing a scientific paper. Despite this global agreement, in today's "Cross Check Era", too many authors do not give attention to the current standards of systematic research. Thus, the purpose of this paper is to describe these performance standards, the available choices for orthopaedic surgeons and the current learning curve for seasoned teams of researchers and orthopaedic surgeons with more than three decades of experience. These lead to provide an accessible overview of all important aspects of the topics that will significantly influence the research development as we arrive at an important globalisation era in orthopaedics and trauma-related research.

AB fMRI studies have linked the posteromedial cortex to episodic learning (encoding) and remembering (retrieval) processes. The posteromedial cortex is considered part of the default network and tends to deactivate during encoding but activate during retrieval, a pattern known as the encoding/retrieval flip. Yet, the exact relationship between the neural correlates of memory performance (hit/miss) and memory stage (encoding/retrieval) and the extent of overlap with intrinsic cortical networks remains to be elucidated. Using task-based fMRI, we isolated the pattern of activity associated with memory performance, memory stage, and the interaction between both. Using resting-state fMRI, we identified which intrinsic large-scale functional networks overlapped with regions showing task-induced effects. Our results demonstrated an effect of successful memory performance in regions associated with the control network and an effect of unsuccessful memory performance in the ventral attention network. We found an effect of memory retrieval in brain regions that span the default and control networks. Finally, we found an interaction between memory performance and memory stage in brain regions associated with the default network, including the posteromedial cortex, posterior parietal cortex, and parahippocampal cortex. We discuss these findings in relation to the encoding/retrieval flip. In general, the findings demonstrate that task-induced effects cut across intrinsic cortical networks. Furthermore, regions within the default network display functional dissociations, and this may have implications for the neural underpinnings of age-related memory disorders.

AB Background and Aim In Taiwan, unsedated esophagogastroduodenoscopy (EGD) is widely used, but it is uncomfortable for some patients. While meperidine has been adopted in colonoscopy, its use in EGD has not received extensive attention. This was a prospective study to investigate the use of meperidine as a single sedative agent during EGD. Methods One hundred and forty patients were randomized to receive either 25-mg meperidine (n=70) or placebo (n=70) by intramuscular injection before EGD. The primary outcome was patient discomfort scores. The secondary outcomes included patient, endoscopist, and EGD-related variables. Results Patients in the meperidine group reported less discomfort during esophageal intubation (median score of 2.0 and interquartile range [IQR] of 0-4.0 vs median score of 4.8 and IQR of 1.7-7.0, respectively; P<0.001) and during the procedure (median score of 1.0 [IQR 0-3.1] vs 3.5 [IQR 0-5.6], P=0.001) than patients in the placebo group. The endoscopist found patients in the meperidine group had better tolerance during esophageal intubation (median score of 1.0 [IQR 0-2.0] vs 2.0 [IQR 1.0-3.0], P=0.021) and during the procedure (median score of 0 [IQR 0-1.0] vs 1.0 [IQR 0-3.0], P<0.001). After the procedure more patients in the meperidine group (71.4% vs 35.7%, P<0.001) experienced self-limited dizziness that prolonged recovery by approximate to 3.7min. Conclusions After receiving meperidine injection, patients had better tolerance and less discomfort during diagnostic EGD (NCT01547520).

TI Virus-Specific Effects of TRIM5 alpha(rh) RING Domain Functions on
Restriction of Retroviruses

DOMAIN; MONKEY TRIM5-ALPHA; SEQUENCE VARIATION; HIV-1 RESTRICTION
AB The tripartite motif protein TRIM5 alpha restricts particular retrovirus infections by binding to the incoming capsid and inhibiting the early stage of virus infection. The TRIM5 alpha RING domain exhibits E3 ubiquitin ligase activity and assists the higher-order association of TRIM5 alpha dimers, which promotes capsid binding. We characterized a panel of RING domain mutants of the rhesus monkey TRIM5 alpha (TRIM5 alpha(rh)) protein. The RING domain function that significantly contributed to retroviral restriction depended upon the restricted virus. The E3 ubiquitin ligase activity of the RING domain contributes to the potency of HIV-1 restriction. Nonetheless, TRIM5 alpha(rh) mutants without detectable E3 ubiquitin ligase activity still blocked reverse transcription and inhibited HIV-1 infection at a moderate level. When TRIM5 alpha(rh) capsid binding was weakened by substitution with a less efficient B30.2/SPRY domain, the promotion of higher-order association by the RING domain was more important to HIV-1 restriction than its E3 ubiquitin ligase activity. For the restriction of N-tropic murine leukemia virus (N-MLV) and equine infectious anemia virus (EIAV) infection, promotion of higher-order association represented the major contribution of the RING domain. Thus, both identity of the target virus and the B30.2/SPRY domain-mediated affinity for the viral capsid determine the relative contribution of the two known RING domain functions to TRIM5 alpha restriction of retrovirus infection.

AB All-trans retinoic acid (ATRA) used for the treatment of APL can lead to the development of differentiation syndrome (DS), a potentially life threatening complication. Since ATRA is metabolized by cytochrome P450 (CYP) enzymes, we sought to identify drug interactions that might be associated with a higher risk for the development of DS in addition to other predictive factors related to the incidence of DS. We identified 60 consecutive patients with APL treated at our institution with ATRA from May 2004 until January 2010. Of the 60 patients identified, 29 (48%) developed DS within a median of 5 days (range 1-31) of ATRA initiation. We did not find any difference in overall incidence of DS whether patients were on concurrent CYP 2C8, 2C9 or 3A4 inhibitors, inducers or substrates. In multivariable analysis, higher peripheral blood blast counts on admission (p = 0.04) as well as higher body mass index (p = 0.003) were associated with developing DS. Out of the 29 patients with DS, there were 4 early deaths of which 2 were attributed to DS compared to no early deaths in the patients who did not develop DS (p = 0.05). Regarding disease-related outcomes, only CR rate was different between patients developing DS versus those who did not develop DS. (C) 2013 Elsevier Ltd. All rights reserved.

All complete responders (CR) received consolidation chemotherapy, then randomized to 1 year ATRA or observation. 245 patients received ATRA sometime during the study: 195 (80%) achieved a CR. Nine (4.6%) relapsed late (>3 years from CR), the last occurred after 4.6 years; 7 of them were still alive after 5.5-15 years. In APL patients, late relapses are uncommon, and those who sustain CR >5 years can be considered cured. (C) 2013 Elsevier Ltd. All rights reserved.

AB Histone deacetylases (HDACs) mediate protein acetylation states, which in turn regulate normal cellular processes often dysregulated in cancer. These observations led to the development of HDAC inhibitors that target tumors through multiple effects on protein acetylation. Clinical evidence demonstrates that treatment with HDAC inhibitors (such as vorinostat, panobinostat, and romidepsin) in combination with other antimyeloma agents (such as proteasome inhibitors and immunomodulatory drugs) has promising antitumor activity in relapsed/refractory multiple myeloma patients. This mini-review highlights the role of protein acetylation in the development of cancers and the rationale for the use of HDAC inhibitors in this patient population. (C) 2013 Elsevier Ltd.

AB A 64-channel brain array coil was developed and compared to a 32-channel array constructed with the same coil former geometry to precisely isolate the benefit of the 2-fold increase in array coil elements. The constructed coils were developed for a standard clinical 3T MRI scanner and used a contoured head-shaped curved former around the occipital pole and tapered in at the neck to both improve sensitivity and patient comfort. Additionally, the design is a compact, split-former design intended for robust daily use. Signal-to-noise ratio and noise amplification (G-factor) for parallel imaging were quantitatively evaluated in human imaging and compared to a size and shape-matched 32-channel array coil. For unaccelerated imaging, the 64-channel array provided similar signal-to-noise ratio in the brain center to the 32-channel array and 1.3-fold more signal-to-noise ratio in the brain cortex. Reduced noise amplification during highly parallel imaging of the 64-channel array provided the ability to accelerate at approximately one unit higher at a given noise amplification compared to the sized-matched 32-channel array. For example, with a 4-fold acceleration rate, the central brain and cortical signal-to-noise ratio of the 64-channel array was 1.2- and 1.4-fold higher, respectively, compared to the 32-channel array. The characteristics of the coil are demonstrated in accelerated brain imaging. Magn Reson Med, 2013. (c) 2012 Wiley Periodicals, Inc.

AB Central sensitization and dysregulation of peripheral substance P and neurokinin-1 receptor (NK-1R) signaling are associated with chronic abdominal pain in inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Although positron emission tomography (PET) has demonstrated that patients with injury-related chronic pain have diminished NK-1R availability in the brain, it is unknown whether these deficits are present in IBD and IBS patients, who have etiologically distinct forms of non-injury-related chronic pain. This study's aim was to determine if patients with IBD or IBS exhibit deficits in brain expression of NK-1Rs relative to healthy controls (HCs), the extent to which expression patterns differ across patient populations, and if these patterns differentially relate to clinical parameters. PET with [F-18] SPA-RQ was used to measure NK-1R availability by quantifying binding potential (BP) in the 3 groups. Exploratory correlation analyses were performed to detect associations between NK-1R BP and physical symptoms. Compared to HCs, IBD patients had NK-1R BP deficits across a widespread network of cortical and subcortical regions. IBS patients had similar, but less pronounced deficits. BP in a subset of these regions was robustly related to discrete clinical parameters in each patient population. Widespread deficits in NK-1R BP occur in IBD and, to a lesser extent, IBS; however, discrete clinical parameters relate to NK-1R BP in each patient population. This suggests that potential pharmacological interventions that target NK-1R signaling may be most effective for treating distinct symptoms in IBD and IBS.

AB The AMPK/SNF1/SnRK1 protein kinases are a family of ancient and highly conserved eukaryotic energy sensors that function as heterotrimeric complexes. These typically comprise catalytic subunits and regulatory and subunits, the latter function as the energy-sensing modules of animal AMPK through adenosine nucleotide binding. The ability to monitor accurately and adapt to changing environmental conditions and energy supply is essential for optimal plant growth and survival, but mechanistic insight in the plant SnRK1 function is still limited. In addition to a family of -like proteins, plants also encode a hybrid protein that combines the Four-Cystathionine -synthase (CBS)-domain (FCD) structure in subunits with a glycogen-binding domain (GBD), typically found in subunits. We used integrated functional analyses by ectopic SnRK1 complex reconstitution, yeast mutant complementation, in-depth phylogenetic reconstruction, and a seedling starvation assay to show that only the hybrid KIN protein that recruited the GBD around the emergence of the green chloroplast-containing plants, acts as the canonical subunit required for heterotrimeric complex formation. Mutagenesis and truncation analysis further show that complex interaction in plant cells and subunit function in yeast depend on both a highly conserved FCD and a pre-CBS domain, but not the GBD. In addition to novel insight into canonical AMPK/SNF/SnRK1 subunit function, regulation and evolution, we provide a new classification of plant FCD genes as a convenient and reliable tool to predict regulatory partners for the SnRK1 energy sensor and novel FCD gene functions.

AB Fragile X syndrome (FXS) is an inherited form of developmental disability and a single gene cause of autism. As a disorder with increasingly understood pathophysiology, FXS is a model form of developmental disability for targeted drug development efforts. Preclinical animal model findings have focused targeted drug treatment development in FXS on an imbalance between excessive glutamate and deficient gamma-aminobutyric acid (GABA) neurotransmission.
We conducted a prospective open-label 10-week trial of acamprosate in 12 youth aged 6-17 years (mean age: 11.9 years) with FXS.
Acamprosate use (mean dose: 1,054 +/- 422 mg/day) was associated with treatment response (defined by a Clinical Global Impressions Improvement (CGI-I) scale score of "very much improved" or "much improved") in nine of 12 (75 %) subjects. Improvement was noted in social behavior and inattention/hyperactivity using multiple standard behavioral outcome measures. No significant adverse effects or changes in vital signs, including weight or laboratory measures, occurred during treatment with acamprosate. Additionally, pre- and post-treatment blood biomarker analyses looking at brain-derived neurotrophic factor (BDNF) levels found a significant increase in BDNF with treatment. In our pilot sample, treatment response did not correlate with change in BDNF with treatment.
Acamprosate was generally safe and well tolerated and was associated with a significant improvement in social behavior and a reduction in inattention/hyperactivity. The increase in BDNF that occurred with treatment may be a useful pharmacodynamic marker in future acamprosate studies. Given these findings, a double-blind, placebo-controlled study of acamprosate in youth with FXS is warranted.

AB Sleep apnea is a common chronic disease that is associated with coronary heart disease, stroke, heart failure and mortality, although the ability of sleep apnea treatment to reduce cardiovascular morbidity and mortality has not been demonstrated. In contrast to patients seeking treatment in sleep disorders centers, as many as half of individuals with moderate to severe sleep apnea in the general population do not report excessive sleepiness; however, if treatment of sleep apnea were shown to reduce cardiovascular disease risk, this would provide a strong rationale for treatment of sleep apnea even in the absence of daytime sleepiness. This article summarizes the status of clinical trials evaluating the potential cardiovascular benefits of sleep apnea treatment and discusses the challenges of conducting such trials, and introduces the International Collaboration of Sleep Apnea Cardiovascular Trialists (INCOSACT), a clinical research collaboration formed to foster cardiovascular sleep research.

AB Study Objectives: To evaluate predeployment sleep duration and insomnia symptoms in relation to the development of mental health symptoms.
Design: Longitudinal cohort study.
Setting: The Millennium Cohort Study survey is administered via a secure website or US mail.
Participants: Data were from 15,204 participants who completed their first deployment between the submissions of 2 consecutive Millennium Cohort questionnaires (2001-2008).
Interventions: N/A.
Measurements and Results: Using self-reported data from the Millennium Cohort Study we evaluated the association of predeployment sleep duration and insomnia symptoms on the development of new-onset mental disorders among deployers. Multivariable logistic regression was used to estimate the odds of developing posttraumatic stress disorder (PTSD), depression, and anxiety, while adjusting for relevant covariates including combat-related trauma. The study outcomes were assessed using validated instruments, including the PTSD checklist-civilian version, and the PRIME-MD Patient Health Questionnaire. We identified 522 people with new-onset PTSD, 151 with anxiety, and 303 with depression following deployment. In adjusted models, combat-related trauma and predeployment insomnia symptoms were significantly associated with higher odds of developing posttraumatic stress disorder, depression, and anxiety postdeployment.
Conclusions: Sleep characteristics, especially insomnia symptoms, are related to the development of mental disorders following military deployments. Assessment of insomnia symptoms predeployment may help to better identify those at highest risk for subsequent adverse mental health outcomes.

SAMPLE
AB Childhood trauma (CT) has been found to be associated with major depressive disorder (MDD) and personality disorders (PD) in adulthood in Western countries, but little is known about the relationship between CT, PD and MDD in sub-Saharan Africa. The present study aims to examine: (1) the frequency of the CT, (2) the association between CT, PD symptoms and MDD and (3) the mediating role of PD between CT and MDD in Togo.
One hundred and eighty-one participants (91 individuals with current MDD and 90 healthy controls without psychiatric history) completed the 28-item CT Questionnaire (CTQ) and the Personality Diagnostic Questionnaire (PDQ-4+).
Participants in the MDD group reported more frequently emotional, sexual and physical abuse and emotional and physical neglect than controls (p < 0.001). There was a significant positive correlation between the total abuse and the PDQ-4 + score (r = 0.48, p < 0.01) in the total sample. Emotional and sexual abuses were associated with current MDD and the number of PD criteria endorsed. Furthermore, PD symptoms mediated partially the relationship between CT and current MDD.
Our results suggest an association between CT and current MDD in French-speaking sub-Saharan Africa, and that this relationship may be explained by PD symptoms. Prospective studies to confirm these results are warranted.

AB Objectives Protection of workers from second-hand smoke (SHS) in occupational settings is an important policy priority, yet little attention has been given to SHS protection for home visitation health workers, who number almost 2 million in the USA. Self-reported SHS exposure, SHS mitigation strategies and suggestions for further SHS exposure reduction approaches were obtained from home visitation health workers in Massachusetts.
Methods A cross-sectional survey was conducted among Massachusetts Early Intervention workers (N=316) at their state-wide conference in April 2010.
Results Eighty-three per cent of respondents reported at least 1 hour per month of SHS exposure, and 16% reported at least 11 hours per month. Nevertheless, only 22% of workers counselled clients on maintaining a smoke-free home. Fewer than 30% of workers had ever voiced concerns to their employing agency, and just 12% had raised their concerns directly with clients. Only 14% stated that their agency had rules designed to protect workers from SHS.
Conclusions SHS exposure occurs frequently among home visitation health workers. The data point to a substantial population who are not protected from SHS exposure by formal policies.

AB Glutathione (GSH), the most abundant intracellular low molecular mass thiol, protects cells from oxidative damage and regulates their function. Available information is inconsistent regarding levels of GSH and its disulfide (GSSG) in maintenance hemodialysis patients (HD). In addition, very limited data are available in HD about the relationship of GSH and GSSG with other measures of thiol metabolism and with the clinical profile. We tested the hypothesis that erythrocyte GSH/GSSG redox potential (Eh) is lower in HD than in healthy controls (C), and that Eh correlates with posttranslational thiolation of hemoglobin (Hb) and with standard clinical parameters in HD. In cross-sectional comparison of 33 stable HD and 21 C, we found a net loss of reducing capacity in HD as indicated by low erythrocyte GSH/GSSG Eh (-257 +/- 5.5 vs -270 +/- 5.6 mV, P = 0.002). Glutathionylated Hb (HbSSG) was 46% higher in HD than C (19.3 +/- 4.80 vs 13.2 +/- 2.79 pmol/mg Hb; P = 0.001) and cysteinylated Hb (HbSSCy) was >3-fold higher in HD than C (38.3 (29.0-63.3) vs 11.5 (9.6-17.2) pmol/mg Hb; P = 0.001). In multiple regression analysis of the HD cases, statistically significant associations were found between the GSH/GSSG Et, and the blood urea nitrogen (P = 0.001), creatinine (P = 0.015) and normalized protein catabolic rate (P = 0.05), after adjusting for age, race/ethnicity, and etiology of end-stage renal disease. In conclusion, accurate and precise analysis of GSH, GSSG, and mixed disulfides reveals loss of erythrocyte GSH/GSSG Eh, rise of both HbSSG and HbSSCy, and correlation of these thiols with measures of uremia and dietary protein intake.

AB Numerous research groups are now using analysis of blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) results and relaying back information about regional activity in their brains to participants in the scanner in real time'. In this study, we explored the feasibility of self-regulation of frontal cortical activation using real-time fMRI (rtfMRI) neurofeedback in nicotine-dependent cigarette smokers during exposure to smoking cues. Ten cigarette smokers were shown smoking-related visual cues in a 3 Tesla MRI scanner to induce their nicotine craving. Participants were instructed to modify their craving using rtfMRI feedback with two different approaches. In a reduce craving' paradigm, participants were instructed to reduce' their craving, and decrease the anterior cingulate cortex (ACC) activity. In a separate increase resistance' paradigm, participants were asked to increase their resistance to craving and to increase middle prefrontal cortex (mPFC) activity. We found that participants were able to significantly reduce the BOLD signal in the ACC during the reduce craving' task (P=0.028). There was a significant correlation between decreased ACC activation and reduced craving ratings during the reduce craving' session (P=0.011). In contrast, there was no modulation of the BOLD signal in mPFC during the increase resistance' session. These preliminary results suggest that some smokers may be able to use neurofeedback via rtfMRI to voluntarily regulate ACC activation and temporarily reduce smoking cue-induced craving. Further research is needed to determine the optimal parameters of neurofeedback rtfMRI, and whether it might eventually become a therapeutic tool for nicotine dependence.

AB Policymakers are investing significant resources in large-scale training and implementation programs for evidence-based psychological treatments (EBPTs) in public mental health systems. However, relatively little research has been conducted to understand factors that may influence the success of efforts to implement EBPTs for adult consumers of mental health services. In a formative investigation during the development of a program to implement cognitive therapy (CT) in a community mental health system, we surveyed and interviewed clinicians and clinical administrators to identify potential influences on CT implementation within their agencies. Four primary themes were identified. Two related to attitudes towards CT: (1) ability to address client needs and issues that are perceived as most central to their presenting problems, and (2) reluctance to fully implement CT. Two themes were relevant to context: (1) agency-level barriers, specifically workload and productivity concerns and reactions to change, and (2) agency-level facilitators, specifically, treatment planning requirements and openness to training. These findings provide information that can be used to develop strategies to facilitate the implementation of CT interventions for clients being treated in public-sector settings.

AB To improve methods of estimating use of evidence-based psychotherapy for posttraumatic stress disorder in the Veteran's health administration, we evaluated administrative data and note text for patients newly enrolling in six VHA outpatient PTSD clinics in New England during the 2010 fiscal year (n = 1,924). Using natural language processing, we developed machine learning algorithms that mimic human raters in classifying note text. We met our targets for algorithm performance as measured by precision, recall, and F-measure. We found that 6.3 % of our study population received at least one session of evidence-based psychotherapy during the initial 6 months of treatment. Evidence-based psychotherapies appear to be infrequently utilized in VHA outpatient PTSD clinics in New England. Our method could support efforts to improve use of these treatments.

AB This paper used qualitative methods to explore experiences of men who have sex with men and female sex workers in Nairobi and Mtwapa, Kenya, who used oral pre-exposure prophylaxis (PrEP) for HIV prevention as part of a four-month trial of safety, acceptability and adherence. Fifty-one of 72 volunteers who took part in a randomized, placebo-controlled, blinded trial that compared daily and intermittent dosage of PrEP underwent qualitative assessments after completing the trial. Analyses identified three themes: (i) acceptability of PrEP was high, i.e. side effects were experienced early in the study but diminished over time, however characteristics of pills could improve comfort and use; (ii) social impacts such as stigma, rumors, and relationship difficulties due to being perceived as HIV positive were prevalent; (iii) adherence was challenged by complexities of daily life, in particular post-coital dosing adherence suffered from alcohol use around time of sex, mobile populations, and transactional sex work. These themes resonated across dosing regimens and gender, and while most participants favored the intermittent dosing schedule, those in the intermittent group noted particular challenges in adhering to the post-coital dose. Culturally appropriate and consistent counseling addressing these issues may be critical for PrEP effectiveness.

ID SYMPTOMS
AB Posttraumatic stress disorder (PTSD) and partner relationship difficulties commonly co-occur among Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF-OIF). This study reports upon results for six male OEF-OIF Veterans with PTSD and their female relationship partners who completed cognitive-behavioral conjoint therapy for PTSD (CBCT for PTSD), which is a treatment that targets reductions in PTSD and couple distress. Case- and group-level data supported reductions in Veterans' PTSD symptoms and female partners' relationship distress. These findings suggest that CBCT for PTSD may be a promising intervention for OEF-OIF Veterans' PTSD and their partners.

ID CONSENSUS CONFERENCE; RHABDOMYOMA; TUMORS
AB Tuberous sclerosis complex (TSC) is a highly variable, multisystem, genetic disorder that affects approximately 1:6,000 individuals. It has previously been thought that the cardiac manifestation of TSC is congenital rhabdomyomas, which occur during infancy and typically regress during childhood. Recently, there have been findings of cardiac fat-containing lesions in adult TSC patients that appear distinct from the presence of cardiac rhabdomyomas. We review the chest CT scans of 73 individuals with TSC to check for cardiac fat-containing lesions. Fat-containing lesions were found in the heart of approximately one-third of adolescents and adults with TSC. In this population with cardiac fat-containing lesions, no statistically significant difference was observed between the genders and between the different mutation types. Compared to those without cardiac fat findings, those with cardiac fat were more than twice as likely to have another abdominal manifestation of TSC. The results indicate that it may be appropriate to consider these cardiac fat foci as a clinical criterion for the diagnosis of TSC, given their frequency in our population. Our findings also suggest that a relation exists between the cardiac fat-containing lesions and other abdominal angiomyolipomas. More research regarding these cardiac fat-containing lesions is needed to better characterize their origin and clinical significance. (c) 2013 Wiley Periodicals, Inc.

AB Endometriosis is an angiogenesis-dependent disease. Many studies demonstrated inhibition of angiogenesis leads to inhibition of endometriotic growth, however underlying mechanism is still not fully understood. Our previous study suggested vascular endothelial growth factor C (VEGF-C) as a target of anti-angiogenesis therapy for endometriosis. In this study, VEGF-C in endometrium and its role in angiogenesis of endometriosis were studied. Human endometrium were obtained from women with and without endometriosis for molecular studies. VEGF-A, VEGF-B, VEGF-C and VEGF-D mRNA and proteins in eutopic and ectopic endometrium were measured. Human endothelial cells were transfected with VEGF-C siRNA in vitro, effects of VEGF-C on endothelial cell migration, invasion and tube formation were investigated in vitro. Angiogenesis was inhibited in wild type mice, vascular permeability in dermal skin was determined in vivo. Transplanted endometrium were inhibited by VEGF-C siRNA in immunocompromised mice, development, growth and angiogenesis of the experimental endometriosis were compared in vivo. The results showed that VEGF-C mRNA and protein were increased in eutopic and ectopic endometrium of endometriosis patients. VEGF-C siRNA significantly inhibited endothelial cell migration and tube formation. VEGF-C siRNA significantly inhibited development and angiogenesis of the experimental endometriotic lesions in mice. Supplementation and over-expression of VEGF-C significantly reversed the inhibitory effects on the endothelial functions, vascular permeability and endometriotic growth. In conclusion, VEGF-C is increased in endometrium and it promotes endothelial functions, vascular permeability and development of experimental endometriosis. VEGF-C is important for angiogenesis in endometriosis.

AB Arteries are composed of multiple constituents that endow the wall with proper structure and function. Many vascular diseases are associated with prominent mechanical and biological alterations in the wall constituents. In this study, planar biaxial tensile test data of elastase-treated porcine aortic tissue (Chow et al. in Biomech Model Mechanobiol 2013) is re-examined to characterize the altered mechanical behavior at multiple stages of digestion through constitutive modeling. Exponential-based as well as recruitment-based strain energy functions are employed and the associated constitutive parameters for individual digestion stages are identified using nonlinear parameter estimation. It is shown that when the major portion of elastin is degraded from a cut-open artery in the load-free state, the embedded collagen fibers are recruited at lower stretch levels under biaxial loads, leading to a rapid stiffening behavior of the tissue. Multiphoton microscopy illustrates that the collagen waviness decreases significantly with the degradation time, resulting in a rapid recruitment when the tissue is loaded. It is concluded that even when residual stresses are released, there exists an intrinsic mechanical interaction between arterial elastin and collagen that determines the mechanics of arteries and carries important implications to vascular mechanobiology.

AB Surgical scaffold materials manufactured from donor human or animal tissue are increasingly being used to promote soft tissue repair and regeneration. The clinical product consists of the residual extracellular matrix remaining after a rigorous decellularization process. Optimally, the material provides both structural support during the repair period and cell guidance cues for effective incorporation into the regenerating tissue. Surgical scaffold materials are available from several companies and are unique products manufactured by proprietary methodology. A significant need exists for a more thorough understanding of scaffold properties that impact the early steps of host cell recruitment and infiltration. In this study, a panel of in vitro assays was used to make direct comparisons of several similar, commercially-available materials: Alloderm, Medeor Matrix, Permacol, and Strattice. Differences in the materials were detected for both cell signaling and scaffold architecture-dependent cell invasion. Material-conditioned media studies found Medeor Matrix to have the greatest positive effect upon cell proliferation and induction of migration. Strattice provided the greatest chemotaxis signaling and best suppressed apoptotic induction. Among assays measuring structure-dependent properties, Medeor Matrix was superior for cell attachment, followed by Permacol. Only Alloderm and Medeor Matrix supported chemotaxis-driven cell invasion beyond the most superficial zone. Medeor Matrix was the only material in the chorioallantoic membrane assay to support substantial cell invasion. These results indicate that both biologic and structural properties need to be carefully assessed in the considerable ongoing efforts to develop new uses and products in this important class of biomaterials.

AB Immuno-isolation of islets has the potential to enable the replacement of pancreatic function in diabetic patients. However, host response to the encapsulated islets frequently leads to fibrotic overgrowth with subsequent impairment of the transplanted grafts. Here, we identified and incorporated anti-inflammatory agents into islet-containing microcapsules to address this challenge. In vivo subcutaneous screening of 16 small molecule anti-inflammatory drugs was performed to identify promising compounds that could minimize the formation of fibrotic cell layers. Using parallel non-invasive fluorescent and bioluminescent imaging, we identified dexamethasone and curcumin as the most effective drugs in inhibiting the activities of inflammatory proteases and reactive oxygen species in the host response to subcutaneously injected biomaterials. Next, we demonstrated that co-encapsulating curcumin with pancreatic rat islets in alginate microcapsules reduced fibrotic overgrowth and improved glycemic control in a mouse model of chemically-induced type I diabetes. These results showed that localized administration of anti-inflammatory drug can improve the longevity of encapsulated islets and may facilitate the translation of this technology toward a long-term cure for type I diabetes.

AB Resampling-based expression pathway analysis techniques have been shown to preserve type I error rates, in contrast to simple gene-list approaches that implicitly assume the independence of genes in ranked lists. However, resampling is intensive in computation time and memory requirements. We describe accurate analytic approximations to permutations of score statistics, including novel approaches for Pearson's correlation, and summed score statistics, that have good performance for even relatively small sample sizes. Our approach preserves the essence of permutation pathway analysis, but with greatly reduced computation. Extensions for inclusion of covariates and censored data are described, and we test the performance of our procedures using simulations based on real datasets. These approaches have been implemented in the new R package safeExpress.

AB The Eating Disorder Examination adapted for children (ChEDE) is the child version of the semi-structured gold standard eating disorder interview for adults. This study was a comprehensive test statistic evaluation of the German ChEDE in a large sample of children and adolescents with anorexia nervosa, binge eating disorder, loss of control eating, overweight and obesity, as well as non-eating-disordered and chronically ill control probands (n=352). Excellent inter-rater reliability, adequate internal consistency and satisfactory stability of ChEDE indicators were demonstrated. ChEDE indicators discriminated between diverse forms of eating and weight disturbances and normative eating and were significantly correlated with conceptually related measures. Factorial validity was not convincing; a brief eight-item scale showed the best fit. Item statistics were mostly acceptable. Overall, the ChEDE's German translation reliably and validly assesses psychopathology across the eating and weight disorder spectrum and facilitates international comparison of eating disorder research.

AB Identification of gene-environment interaction (G x E) is important in understanding the etiology of complex diseases. However, partially due to the lack of power, there have been very few replicated G x E findings compared to the success in marginal association studies. The existing G x E testing methods mainly focus on improving the power for individual markers. In this paper, we took a different strategy and proposed a set-based gene-environment interaction test (SBERIA), which can improve the power by reducing the multiple testing burdens and aggregating signals within a set. The major challenge of the signal aggregation within a set is how to tell signals from noise and how to determine the direction of the signals. SBERIA takes advantage of the established correlation screening for G x E to guide the aggregation of genotypes within a marker set. The correlation screening has been shown to be an efficient way of selecting potential G x E candidate SNPs in case-control studies for complex diseases. Importantly, the correlation screening in case-control combined samples is independent of the interaction test. With this desirable feature, SBERIA maintains the correct type I error level and can be easily implemented in a regular logistic regression setting. We showed that SBERIA had higher power than benchmark methods in various simulation scenarios, both for common and rare variants. We also applied SBERIA to real genome-wide association studies (GWAS) data of 10,729 colorectal cancer cases and 13,328 controls and found evidence of interaction between the set of known colorectal cancer susceptibility loci and smoking.

TI Measurements of three-dimensional shape and sound-induced motion of the
chinchilla tympanic membrane
SO HEARING RESEARCH
LA English
DT Article
ID WAVE MODEL; EARDRUM; HOLOGRAPHY; SURFACE
AB Opto-electronic computer holographic measurements were made of the tympanic membrane (TM) in cadaveric chinchillas. Measurements with two laser wavelengths were used to compute the 3D-shape of the TM. Single laser wavelength measurements locked to eight distinct phases of a tonal stimulus were used to determine the magnitude and the relative phase of the surface displacements. These measurements were made at over 250,000 points on the TM surface. The measured motions contained spatial phase variations consistent with relatively low-order (large spatial frequency) modal motions and smaller magnitude higher-order (smaller spatial frequency) motions that appear to travel, but may also be explained by losses within the membrane. The measurement of shape and thin shell theory allowed us to separate the measured motions into those components orthogonal to the plane of the tympanic ring, and those components within the plane of the tympanic ring based on the 3D-shape. The predicted in-plane motion components are generally smaller than the out-of-plane perpendicular component of motion. Since the derivation of in-plane and out-of plane depended primarily on the membrane shape, the relative sizes of the predicted motion components did not vary with frequency.
Summary: A new method for simultaneously measuring the shape and sound-induced motion of the tympanic membrane is utilized to estimate the 3D motion on the membrane surface. This article is part of a Special Issue entitled "MEMRO 2012". (C) 2012 Elsevier B.V. All rights reserved.

TI Evidence of inner ear contribution in bone conduction in chinchilla
SO HEARING RESEARCH

DT Article
ID MIDDLE-EAR; ADMITTANCE; PRESSURE
AB We investigated the contribution of the middle ear to the physiological response to bone conduction stimuli in chinchilla. We measured intracochlear sound pressure in response to air conduction (AC) and bone conduction (BC) stimuli before and after interruption of the ossicular chain at the incudostapedial joint. Interruption of the chain effectively decouples the external and middle ear from the inner ear and significantly reduces the contributions of the outer ear and middle ear to the bone conduction response. With AC stimulation, both the scala vestibuli Psv and scala tympani Pst sound pressures drop by 30-40 dB after the interruption. In BC stimulation, Psv decreases after interruption by about 10-20 dB, but Pst is little affected. This difference in the sensitivity of the BC induced Psv and Pst to ossicular interruption is not consistent with a BC response to ossicular motion, but instead suggests a significant contribution of an inner-ear drive (e.g. cochlear fluid inertia or compressibility) to the BC response.

AB The cochlea is normally driven with "forward" stimulation, in which sound is introduced to the ear canal. Alternatively, the cochlea can be stimulated at the round window (RW) using an actuator. During RW "reverse" stimulation, the acoustic flow starting at the RW does not necessarily take the same path as during forward stimulation. To understand the differences between forward and reverse stimulation, we measured ear-canal pressure, stapes velocity, RW velocity, and intracochlear pressures in scala vestibuli (SV) and scala tympani (ST) of fresh human temporal bones. During forward stimulation, the cochlear drive (differential pressure across the partition) results from the large difference in magnitude between the pressures of SV and ST, which occurs due to the high compliance of the RW. During reverse stimulation, the relatively high impedance of the middle ear causes the pressures of SV and ST to have similar magnitudes, and the differential pressure results primarily from the difference in phase of the pressures. Furthermore, the sound path differs between forward and reverse stimulation, such that motion through a third window is more significant during reverse stimulation. Additionally, we determined that although stapes velocity is a good estimate of cochlear drive during forward stimulation, it is not a good measure during reverse stimulation.

AB Objectives Because of concerns regarding interactions between midazolam and antiretroviral therapy (ART), alternative sedatives are sometimes used during procedural sedation. Our objective was to compare outcomes in patients on ART who received intravenous (iv) midazolam vs. iv diazepam, a second-line agent, during colonoscopy. Methods We conducted a retrospective analysis of adult HIV-positive patients who underwent colonoscopy over a 3.5-year period. Primary outcomes were sedation duration, nadir systolic blood pressure (SBP), nadir oxygen saturation, abnormal cardiac rhythm, and change in level of consciousness using a standardized scale. We calculated rates of adverse events according to benzodiazepine use and identified risk factors for complications using univariate and multivariate analyses. Results We identified 136 patients for this analysis: 70 received midazolam-based sedation and 66 received a diazepam-based regimen. There were no significant differences between the two groups with respect to sedation duration (mean 48.0 vs. 45.7 minutes for the midazolam and diazepam groups, respectively; P=0.68), nadir SBP (mean 97.0 vs. 101.6 mmHg; P=0.06), nadir oxygen saturation (mean 94.6 vs. 94.8%; P=0.72) or rate of abnormal cardiac rhythm (11.4 vs. 19.7%; P=0.18). More patients in the midazolam group experienced a depressed level of consciousness (91% vs. 74% in the diazepam group; P=0.0075), but no patient required reversal of sedation or became unresponsive. Conclusions We did not find evidence that patients who received midazolam for procedural sedation had clinical outcomes statistically different from those who received diazepam. These findings should be confirmed in prospective studies or in a randomized controlled trial.

AB The reduction of neural activity in response to repeated stimuli, repetition suppression, is one of the most robust experience-related cortical dynamics known to cognitive neuroscience. Functional magnetic resonance imaging (fMRI) studies during episodic memory encoding have demonstrated repetition suppression in the hippocampus and this reduction has been linked to successful memory formation. An emerging body of functional imaging evidence suggests that the posteromedial cortex, in addition to the medial temporal lobes, may have a pivotal role in successful episodic memory. This area typically deactivates during initial memory encoding, but its functional changes in response to repetitive encoding remain poorly specified. Here, we investigate the repetition-related changes in the posteromedial cortex as well as the hippocampus while the participants underwent an fMRI experiment involving repetitive encoding of face-name pairs. During the first encoding trial of face-name pairs, significant activation in the hippocampus was observed. The second and third encoding trials demonstrated a repetition suppression effect in the hippocampus, indicated by a stepwise decrease of activation. In contrast, the posteromedial cortex demonstrated significant deactivation during the initial encoding trial of face-name pairs. The second and third encoding trials demonstrated a stepwise decrease of deactivation, repetition enhancement, with activity at or above baseline levels in the final encoding trial. These findings demonstrate that hippocampus repetition suppression as well as posteromedial repetition enhancement is related to successful encoding processes and are discussed in relation to the default mode hypothesis as well as potential implications for understanding late-life amnestic disorders.

AB Fli-1 belongs to the Ets transcription factor family and is expressed in haematopoietic cells, including most of the cells that are active in immunity. The mononuclear phagocytes, i.e. monocytes, macrophages and dendritic cells, originate in haematopoietic stem cells and play an important role in immunity. To assess the role of Fli-1 in mononuclear phagocyte development in vivo, we generated mice that express a truncated Fli-1 protein, lacking the C-terminal transcriptional activation domain (Fli-1CTA). Fli-1CTA/CTA mice had significantly increased populations of haematopoietic stem cells and common dendritic cell precursors in bone marrow compared with wild-type littermates. Significantly increased classical dendritic cells, plasmacytoid dendritic cells, and macrophage populations were found in spleens from Fli-1CTA/CTA mice compared with wild-type littermates. Fli-1CTA/CTA mice also had increased pre-classical dendritic cell and monocyte populations in peripheral blood mononuclear cells. Furthermore, bone marrow reconstitution studies demonstrated that expression of Fli-1 in both haematopoietic cells and stromal cells affected mononuclear phagocyte development in mice. Expression of Fms-like tyrosine kinase 3 ligand (Flt3L), a haematopoietic growth factor, in multipotent progenitors was statistically significantly increased from Fli-1CTA/CTA mice compared with wild-type littermates. Fli-1 protein binds directly to the promoter region of the Flt3L gene. Hence, Fli-1 plays an important role in the mononuclear phagocyte development, and the C-terminal transcriptional activation domain of Fli-1 negatively modulates mononuclear phagocyte development.

AB Evidence suggests that physicians have lower response rates than nonphysicians to mailed surveys. It is important to identify methods that can increase physician and nurse participation in health-related survey research. In an effort to improve response rates among clinicians, we developed esthetically enhanced survey materials (booklets printed on glossy paper with color and graphic designs) as part of a large mailed-survey study of oncology doctors and nurses who were listed as members of a North American cooperative oncology group. We randomized these clinicians to receive either an enhanced (90%) or standard (10%) paper survey (standard white paper with no color nor graphic designs, stapled together) about offering results of clinical trials to trial participants. Overall, 34% (793/2333) of the surveys were returned. There was no significant difference between the two groups; 33.7% (707/2300) responded to the enhanced materials and 36.9% (86/233) responded to the standard materials (p=.34). These results suggest that esthetically enhanced materials do not increase clinician response rates to mailed surveys, although further research is warranted in this area.

AB We determined whether bone mineral density (BMD) is lower in boys with autism spectrum disorders (ASD) than controls, and also assessed variables that may affect BMD in ASD. BMD was measured using dual energy X-ray absorptiometry (DXA) in 18 boys with ASD and 19 controls 8-14 years old. Boys with ASD had lower BMD Z-scores at the spine, hip and femoral neck, and differences at the hip and femoral neck persisted after controlling for maturity and BMI. Vitamin D intake from food and in serum were lower in ASD subjects, as was exercise activity. We conclude that BMD is lower in peripubertal boys with ASD and may be associated with impaired vitamin D status and lower exercise activity.

AB The main objective was to review the evidence for management of epilepsy associated with hypothalamic hamartomas. We performed a systemic review of the literature through July 2012 that studied patients with hypothalamic hamartomas and related epilepsy. Articles meeting selection criteria were rated according to the American Academy of Neurology classification of evidence scheme. Recommendations were linked to the strength of the evidence and as follows: (a) precocious puberty is associated more with the pedunculated type and epilepsy typified by gelastic seizures with the sessile form of hypothalamic hamartomas (class III); (b) significant behavioral and cognitive deficits are associated with patients with hypothalamic hamartomas (class III); (c) video electroencephalography (EEG) findings are extremely variable particularly across the different ages and do not affect surgical outcome (class III); d) various surgical techniques (transcallosal and endoscopic resection) resulted in 49% to 54% seizure freedom, 15% with a pterional approach as well as about 40% with radiosurgery (class III).

AB Given the centrality of court interventions to the U.S. response to intimate partner violence (IPV), it is crucial to evaluate their impact on reabuse. To do so, this study examined whether female IPV victims' experiences of abuse in the year following a criminal court case against their partner varied by case outcome or by whether the batterer had or had not been incarcerated. Consistent with prior research, we found no main effect differences in reabuse trajectories by court case outcome or by incarceration. We also examined variables that might moderate the impact of case outcome and incarceration on reabuse and found that although batterer legal history did not affect the impact of case outcome, his age, Time 1 employment status, the couple's Time 1 living arrangement, and duration of abuse did interact with case outcome. No variables tested moderated the relationship between incarceration and reabuse over time. Findings suggest that in certain cases there may be benefits to case outcomes that leave potential consequences hanging over the offender's head. These results also add to the growing body of evidence questioning the efficacy of one-size-fits-all approaches to IPV cases.

AB Although the Medicare Part D coverage gap phase-out should reduce cost-related nonadherence (CRN) among seniors with diabetes, preferential generic prescribing may have already decreased CRN, while smaller numbers of patients using more costly branded oral anti-diabetic (OAD) medications remain vulnerable to CRN.
To estimate the effects of cost sharing in the Part D standard (non-LIS) benefit on adherence to different OAD classes, comparing two classes dominated by inexpensive generic medications and two by more costly branded medications.
Retrospective cohort study using dispensed prescription data for elderly non-LIS (N = 81,047) and LIS (low-income subsidy) (N = 150,359) beneficiaries using same class OAD(s) in 2008 and 2009. Logistic regression modeled non-LIS likelihood; LIS and non-LIS patients matched using propensity outcome (N = 38,054). Logistic regression, controlling for demographic and health status characteristics, modeled effects of non-LIS coverage on 2009 OAD class adherence.
Main outcome measures were within-class OAD coverage year adherence, with patients considered adherent when days supplied to calendar days ratio at least 0.8.
Non-LIS patients had 0.52 and 0.57 times the odds of branded-only DPP-4 Inhibitor (N = 1,812; 95 % CI: 0.43, 0.63; P < 0.001) and Thiazolidinedione (TZD) (N = 6,290; 95 % CI: 0.52, 0.63; P < 0.001) adherence. Most patients (N = 32,510; 82 %) used OADs in primarily generic classes, where we found no significant (Biguanides; N = 21,377) or small differences (Sulfonylureas/Glinides [N = 19,240; OR: 0.91; 95 % CI: 0.86, 0.97; P = 0.002]) in adherence odds. Crude adherence rates were sub-optimal when CRN was not a factor (Non-LIS/LIS: Biguanides: 65 %/65 %; Sulfonylureas/Glinides: 66 %/68 %; LIS: DPP-4 Inhibitors: 66 %; TZDs: 67 %).
Gap elimination would not affect generic, but should reduce branded OAD CRN. Branded copayments may continue to lead to CRN. Policy initiatives and benefit changes targeting both cost deterrents for patients with more complex disease and non-cost generic OAD underuse are recommended.

AB Post-traumatic stress disorder (PTSD) is common in women veterans (WVs), and associated with significant co-morbidity. Effective treatment is available; however, PTSD is often unrecognized.
Identify PTSD prevalence and mental healthcare (MHC) use in a representative national WV sample.
Cross-sectional, population-based 2008-2009 national survey of 3,611 WVs, weighted to the population.
We screened for PTSD using a validated instrument, and also assessed demographic characteristics, health characteristics, and MHC use in the prior 12 months. Among those screening positive, we conducted multivariate logistic regression to identify independent predictors of MHC use.
Overall, 13.0 % (95 % confidence interval [CI] 9.8-16.2) of WVs screened PTSD-positive. Veterans Health Administration (VA) healthcare was used by 31.1 % of PTSD-positives and 11.4 % of PTSD-negatives (p < 0.001). Among those screening positive, 48.7 % (95 % CI 35.9-61.6) used MHC services (66.3 % of VA-users, 40.8 % of VA-nonusers; p < 0.001). Having a diagnosis of depression (OR = 8.6; 95 % CI 1.5-48.9) and VA healthcare use (OR = 2.7; 95 % CI 1.1-7.0) predicted MHC use, whereas lacking a regular provider for health care (OR = 0.2; 95 % CI 0.1-0.4) and household income below the federal poverty level (OR = 0.2; 95 % CI 0.1-0.5) predicted nonuse.
More than one in eight WVs screened positive for PTSD. Though a majority of VA-users received MHC, low income predicted nonuse. Only a minority of VA-nonusers received MHC. The majority of WVs use non-VA healthcare providers, who may be unaware of their veteran status and PTSD risk. VA outreach to educate VA-nonusers and their healthcare providers about WVs' PTSD risk and available evidence-based VA treatment options is one approach to extend the reach of VA MHC. Research to characterize barriers to VA MHC use for VA-nonusers and low income VA-users is warranted to better understand low service utilization, and to inform program development to engage more WVs in needed MHC.

AB The Department of Veterans Affairs (VA) instituted the VA Women's Health Fellowship (VAWHF) Program in 1994, to accommodate the health needs of increasing numbers of female veterans and to develop academic leaders in women's health. Despite the longevity of the program, it has never been formally evaluated.
To describe the training environments of VAWHFs and career outcomes of female graduates.
Cross-sectional web-based surveys of current program directors (2010-2011) and VAWHF graduates (1995-2011).
Responses were received from six of seven program directors (86 %) and 42 of 74 graduates (57 %). The mean age of graduates was 41.2 years, and mean time since graduation was 8.5 years. Of the graduates, 97 % were female, 74 % trained in internal medicine, and 64 % obtained an advanced degree. Those with an advanced degree were more likely than those without an advanced degree to pursue an academic career (82 % vs. 60 %; P < 0.01). Of the female graduates, 76 % practice clinical women's health and spend up to 66 % of their time devoted to women's health issues. Thirty percent have held a VA faculty position. Seventy-nine percent remain in academics, with 39 % in the tenure stream. Overall, 94 % had given national presentations, 88 % had received grant funding, 79 % had published in peer-reviewed journals, 64 % had developed or evaluated curricula, 51 % had received awards for teaching or research, and 49 % had held major leadership positions. At 11 or more years after graduation, 33 % of the female graduates in academics had been promoted to the rank of associate professor and 33 % to the rank of full professor.
The VAWHF Program has been successful in training academic leaders in women's health. Finding ways to retain graduates in the VA system would ensure continued clinical, educational, and research success for the VA women veteran's healthcare program.

METAANALYSIS
AB The relationship between blood pressure (BP) and kidney function among individuals with chronic kidney disease (CKD) remains controversial. This study evaluated the association between BP and estimated glomerular filtration rate (eGFR) decline among adults with nondiabetic stage 3 CKD. The Multi-Ethnic Study of Atherosclerosis participants with an eGFR 30-59 ml min(-1) per 1.73 m(2) at baseline without diabetes were included. Participants were followed over a 5-year period. Kidney function change was determined by annualizing the change in eGFR using cystatin C, creatinine and a combined equation. Risk factors for progression of CKD (defined as a decrease in annualized eGFR > 2.5 ml min(-1) per 1.73 m(2)) were identified using univariate analyses and sequential logistic regression models. There were 220 participants with stage 3 CKD at baseline using cystatin C, 483 participants using creatinine and 381 participants using the combined equation. The median (interquartile range) age of the sample was 74 (68-79) years. The incidence of progression of CKD was 16.8% using cystatin C and 8.9% using creatinine (P = 0.002). Systolic BP > 140 mm Hg or diastolic BP > 90 mm Hg was significantly associated with progression using a cystatin C-based (odds ratio (OR), 2.49; 95% confidence interval (CI), 1.12-5.52) or the combined equation (OR, 2.07; 95% CI, 1.16-3.69), but not when using creatinine after adjustment for covariates. In conclusion, with the inclusion of cystatin C in the eGFR assessment hypertension was an important predictor of CKD progression in a multi-ethnic cohort with stage 3 CKD.

IDENTIFICATION
AB Merkel cell carcinomas (MCCs) are rare but highly malignant skin cancers associated with a recently described polyomavirus. MCC tumors were infiltrated by T cells, including effector, central memory, and regulatory T cells. Infiltrating T cells showed markedly reduced activation as evidenced by reduced expression of CD69 and CD25. Treatment of MCC tumors in vitro with IL-2 and IL-15 led to T-cell activation, proliferation, enhanced cytokine production, and loss of viable tumor cells from cultures. Expanded tumor-infiltrating lymphocytes showed TCR repertoire skewing and upregulation of CD137. MCC tumors implanted into immunodeficient mice failed to grow unless human T cells in the tumor grafts were depleted with denileukin diftitox, suggesting that tumor-specific T cells capable of controlling tumor growth were present in MCC. Both CD4(+) and CD8(+) FOXP3(+) regulatory T cells were frequent in MCC. Fifty percent of nonactivated T cells in MCC-expressed PD-1, a marker of T-cell exhaustion, and PD-L1 and PD-L2 were expressed by a subset of tumor dendritic cells and macrophages. In summary, we observed tumor-specific T cells with suppressed activity in MCC tumors. Agents that stimulate T-cell activity, block regulatory T cell function, or inhibit PD-1 signaling may be effective in the treatment of this highly malignant skin cancer.

AB Survivors of pediatric brain tumors are at risk for long-term psychological morbidities. The current study investigated the prevalence and predictors of suicide ideation (SI) in a clinical sample of youth and adult survivors. Retrospective chart reviews were completed for 319 survivors of pediatric brain tumors who were assessed via clinical interview during routine neuro-oncology clinic visits between 2003 and 2007. Survivors were, on average, 18.0 years of age (SD = 4.9) and 10 years from diagnosis (SD = 5.0) at their most recent follow-up. The most common diagnosis was low-grade glioma (n = 162) followed by embryonal tumors (PNET/medulloblastoma; n = 64). Multivariable logistic regression was used to calculate odds ratios (OR) and 95 % confidence intervals (CI) for SI. Nearly 12 % of survivors (11.7 %, n = 37) reported SI. Five survivors (1.5 %) had documented suicide attempts, though none were fatal. In a multivariable model, adjusting for sex and age, history of depression (OR = 20.6, 95 % CI = 4.2-101.1), psychoactive medication treatment (OR = 4.5, 95 % CI = 1.8-11.2), observation or surgery only treatment (OR = 3.7, 95 % CI = 1.5-9.1), and seizures (OR = 3.6, 95 % CI = 1.1-11.1) were significantly associated with SI in survivors. Survivors of pediatric brain tumors appear to be at risk for experiencing SI. Our results underscore the importance of a multidisciplinary approach to providing follow-up care for childhood brain tumor survivors, including routine psychological screenings.

AB The human tyrosine hydroxylase (hTH) gene has a 42bp evolutionarily conserved region designated (CR) II at -7.24kb, which bears 93% homology to the region we earlier identified as containing the glucocorticoid response element, a 7bp activator protein-1 (AP-1)-like motif in the rat TH gene. We cloned this hTH-CRII region upstream of minimal basal hTH promoter in luciferase (Luc) reporter vector, and tested glucocorticoid responsiveness in human cell lines. Dexamethasone (Dex) stimulated Luc activity of hTH-CRII in HeLa cells, while mifepristone, a glucocorticoid receptor (GR) antagonist, prevented Dex stimulation. Deletion of the 7bp 5-TGACTAA at -7243bp completely abolished the Dex-stimulated Luc activity of hTH-CRII construct. The AP-1 agonist, tetradeconoyl-12,13-phorbol acetate (TPA), also stimulated hTH promoter activity, and Dex and TPA together further accentuated this response. Chromatin immunoprecipitation assays revealed the presence of both GR and AP-1 proteins, especially Jun family members, at this hTH promoter site. Dex did not stimulate hTH promoter activity in a catecholaminergic cell line, which had low endogenous GR levels, but did activate the response when GR was expressed exogenously. Thus, our studies have clearly identified a glucocorticoid-responsive element in a 7bp AP-1-like motif in the promoter region at -7.24kb of the human TH gene.

AB This brief report explores the external correlates of 2 higher order structures of the Personality Assessment Inventory (PAI; Morey, 1991, 2007); Hoelzle and Meyer's (2009a, 2009b) PAI Components and Hopwood and Moser's (2011) Internalizing and Externalizing Dimensions. Scores from these higher order structures were correlated with life-event data including education, marital status, employment, suicide attempts, psychiatric hospitalizations, trauma, medical problems, hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrest. Although some differences were noted, the results showed that both Hoelzle and Meyer's Components and Hopwood and Moser's Dimensions were meaningfully correlated with a wide range of life outcomes in a conceptually consistent manner. Overall, these findings provide support for the utility of these higher order variables.

AB Objective Several reports have shown that certain pre-operative CEA intervals can be predictive of long-term outcomes and have subsequently implied that preoperative CEA may be useful to assess the risk of recurrence or death as a continuous number for individual cases. This analysis assesses if this hypothesis is valid after correction for confounders. Methods All colon cancer patients operated on at Massachusetts General Hospital from 2004 through 2011 were considered for retrospective review. Association between outcomes and preoperative CEA was measured in intervals and as a linear relationship. Results Of the 1,071 patients operated for colon adenocarcinoma, 621 (57.9%) had a preoperative CEA drawn and were included in the analysis. In models using intervals, preoperative CEA did show association with (disease-free) survival, but this was shown to be chiefly a surrogate for metastatic presentation. In linear approaches adjusted for metastatic presentation, CEA loses all correlations with metastatic disease (P=0.84), survival (P=0.11), survival duration (P=0.42) and disease-free interval (P=0.94). Conclusions Extrapolating the predictive value of certain preoperative CEA intervals to a continuous approach for use in a case-for-case basis is unjustified. Preoperative CEA may be a useful risk estimator but has limited significance for predictions of long-term outcomes in individual cases. J. Surg. Oncol. 2013;108:14-18.

AB xPGC-1 alpha is a key transcription coactivator regulating energy metabolism in a tissue-specific manner. PGC-1 alpha expression is tightly regulated, it is a highly labile protein, and it interacts with various proteins-the known attributes of intrinsically disordered proteins (IDPs). In this study, we characterize PGC-1 alpha as an IDP and demonstrate that it is susceptible to 20S proteasomal degradation by default. We further demonstrate that PGC-1 alpha degradation is inhibited by NQO1, a 20S gatekeeper protein. NQO1 binds and protects PGC-1 alpha from degradation in an NADH-dependent manner. Using different cellular physiological settings, we also demonstrate that NQO1-mediated PGC-1 alpha protection plays an important role in controlling both basal and physiologically induced PGC-1 alpha protein level and activity. Our findings link NQO1, a cellular redox sensor, to the metabolite-sensing network that tunes PGC-1 alpha expression and activity in regulating energy metabolism.

AB Iron oxide core nanoparticles are attractive imaging agents because their material properties allow the tuning of pharmacokinetics as well as the attachment of multiple moieties to their surface. In addition to affinity ligands, these include fluorochromes and radioisotopes for detection with optical and nuclear imaging. As the iron oxide core can be detected by MRI, options for combining imaging modalities are manifold. Already, preclinical imaging strategies have combined noninvasive imaging with higher resolution techniques, such as intravital microscopy, to gain unprecedented insight into steady-state biology and disease. Going forward, hybrid iron oxide nanoparticles will help to merge modalities, creating a synergy that will enable imaging in basic research and, potentially, also in the clinic.

AB Novel trends in cancer treatment research are focused on targeting the tumor microenvironment, thereby developing chemo-immunotherapeutic strategies which not only directly kill tumor cells, but also trigger the anti-tumor immune effector responses. Ectonucleotidases (CD39 and CD73)-generated extracellular adenosine and cyclooxygenase-2 (COX2)-derived prostaglandin E-2 (PGE(2)) are amongst the tumor microenvironmental factors that have emerged as attractive targets in this regard. Both comprise a pivotal axis in tumor progression and immune escape via autocrine and paracrine activation of a common intracellular signaling pathway, the cAMP-protein kinase A (PKA) pathway, in cancer and immune cells. In this review, we venture a potential and realistic strategy that this adenosine-PGE(2)/cAMP nexus is targetable at different levels, thereby pointing out a 'two hit' chemo-immunotherapeutic proposition: direct killing of tumor cells on one hand, and the rescuing of endogenous anti-tumor immune response on the other. The reviewed experimental, preclinical and clinical data provide the proof of concept that 'two hit' multilevel pharmacological manipulation of adenosine-PGE2/cAMP nexus is achievable within the tumor microenvironment.

AB Affect is basic to many if not all psychological phenomena. This article examines 2 of the most fundamental properties of affective experience-valence and arousal-asking how they are related to each other on a moment to moment basis. Over the past century, 6 distinct types of relations have been suggested or implicitly presupposed in the literature. We critically review the available evidence for each proposal and argue that the evidence does not provide a conclusive answer. Next, we use statistical modeling to verify the different proposals in 8 data sets (with Ns ranging from 80 to 1,417) where participants reported their affective experiences in response to experimental stimuli in laboratory settings or as momentary or remembered in natural settings. We formulate 3 key conclusions about the relation between valence and arousal: (a) on average, there is a weak but consistent V-shaped relation of arousal as a function of valence, but (b) there is large variation at the individual level, so that (c) valence and arousal can in principle show a variety of relations depending on person or circumstances. This casts doubt on the existence of a static, lawful relation between valence and arousal. The meaningfulness of the observed individual differences is supported by their personality and cultural correlates. The malleability and individual differences found in the structure of affect must be taken into account when studying affect and its role in other psychological phenomena.

AB Functional magnetic resonance imaging (fMRI) is a noninvasive method for measuring brain function by correlating temporal changes in local cerebral blood oxygenation with behavioral measures. fMRI is used to study individuals at single time points, across multiple time points (with or without intervention), as well as to examine the variation of brain function across normal and ill populations. fMRI may be collected at multiple sites and then pooled into a single analysis. This paper describes how fMRI data is analyzed at each of these levels and describes the noise sources introduced at each level.

AB Several studies have investigated contextual influences on visual object processing in individuals with autism spectrum disorder (ASD) and failed to find reduced context effects. However, these studies did not properly account for local inter-object effects and/or the influence of post-perceptual processes, leaving it unclear whether individuals with ASD display equally large global top-down effects of context, or whether they rely on a more local mechanism producing the same result. In this study, an eye-movement paradigm was used to investigate implicitly induced context effects on visual object processing in children with ASD compared to matched controls. To find out whether the context effects in the ASD group were, to the same extent, due to early top-down influences on object recognition, we also examined the interaction between context effects and the ease of object recognition. Both groups displayed equally large context effects and congruent contextual information facilitated object recognition to the same extent in both groups. This indicates that the context effects in the ASD group did not result from the operation of a more local, less top-down mechanism. These findings contradict predictions based on the weak central coherence account. However, a good alternative to explain all inconsistencies is currently lacking. (C) 2013 Elsevier Ltd.

AB Biederman J, Petty CR, Spencer TJ, Woodworth KY, Bhide P, Zhu J, Faraone SV. Examining the nature of the comorbidity between pediatric attention deficit/hyperactivity disorder and post-traumatic stress disorder. Objective: This study sought to address the link between attention deficit/hyperactivity disorder (ADHD) and post-traumatic stress disorder (PTSD) in youth by providing a comprehensive comparison of clinical correlates of ADHD subjects with and without PTSD across multiple non-overlapping domains of functioning and familial patterns of transmission. Method: Participants were 271 youths with ADHD and 230 controls without ADHD of both sexes along with their siblings. Participants completed a large battery of measures designed to assess psychiatric comorbidity, psychosocial, educational, and cognitive parameters. Results: Post-traumatic stress disorder was significantly higher in ADHD probands vs. controls (5.2% vs. 1.7%, 2(1)=4.36, P=0.04). Irrespective of the comorbidity with PTSD, ADHD subjects had similar ages at onset of ADHD, similar type and mean number of ADHD symptoms, and similar ADHD-associated impairments. PTSD in ADHD probands was significantly associated with a higher risk of psychiatric hospitalization, school impairment, poorer social functioning and higher prevalences of mood, conduct disorder, and anxiety disorders. The mean onset of PTSD (12.6years) was significantly later than that of ADHD and comorbid disorders (all P<0.05). Siblings of ADHD and ADHD+PTSD probands had higher prevalences of ADHD vs. siblings of controls (35% vs. 18%, z=4.00, P<0.001 and 67% vs. 18%, z=4.02, P<0.001 respectively) and siblings of ADHD+PTSD probands had a significantly higher prevalence of PTSD compared with the siblings of ADHD and control probands (20% vs. 3% and 3%, z=2.99, P=0.003 and z=2.07, P=0.04 respectively). Conclusion: Findings indicate that the comorbidity with PTSD in ADHD leads to greater clinical severity as regards psychiatric comorbidity and psychosocial dysfunction. ADHD is equally familial in the presence of PTSD in the proband indicating that their co-occurrence is not owing to diagnostic error.

AB Objective Lumbar disc degeneration (LDD) is an important cause of low back pain, which is a common and costly problem. LDD is characterised by disc space narrowing and osteophyte growth at the circumference of the disc. To date, the agnostic search of the genome by genome-wide association (GWA) to identify common variants associated with LDD has not been fruitful. This study is the first GWA meta-analysis of LDD.
Methods We have developed a continuous trait based on disc space narrowing and osteophytes growth which is measurable on all forms of imaging (plain radiograph, CT scan and MRI) and performed a meta-analysis of five cohorts of Northern European extraction each having GWA data imputed to HapMap V.2.
Results This study of 4600 individuals identified four single nucleotide polymorphisms with p<5x10(-8), the threshold set for genome-wide significance. We identified a variant in the PARK2 gene (p=2.8x10(-8)) associated with LDD. Differential methylation at one CpG island of the PARK2 promoter was observed in a small subset of subjects (beta=8.74x10(-4), p=0.006).
Conclusions LDD accounts for a considerable proportion of low back pain and the pathogenesis of LDD is poorly understood. This work provides evidence of association of the PARK2 gene and suggests that methylation of the PARK2 promoter may influence degeneration of the intervertebral disc. This gene has not previously been considered a candidate in LDD and further functional work is needed on this hitherto unsuspected pathway.

AB Objective Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), shares clinical and immunological features with psoriasis. Genome-wide association studies have found common susceptibility genes. However, epidemiologic data evaluating the association between psoriasis, psoriatic arthritis and risk of IBD are sparse. We aimed to evaluate the association between psoriasis, psoriatic arthritis and incident CD and UC among women in the USA.
Methods 174 476 women were enrolled in the Nurses' Health Study (NHS) (1996-2008) and NHS II (1991-2007). Lifetime history of physician-diagnosed psoriasis and psoriatic arthritis was confirmed by supplementary questionnaires. Information on CD and UC was obtained by self-reported questionnaires and confirmed by medical record review.
Results We documented 188 incident cases of CD and 240 incident cases of UC during follow-up. Psoriasis was associated with a significantly increased risk of subsequent CD with a multivariate-adjusted relative risk (RR) of 4.00 (95% CI 1.72 to 9.27) for NHS and 3.76 (1.82 to 7.74) for NHS II. By contrast, we did not observe a significant increase in risk of UC associated with psoriasis. In a pooled analysis of both cohorts, women with psoriasis experienced a significantly increased risk of CD (RR, 3.86, 95% CI 2.23 to 6.67), but not UC (RR, 1.17, 95% CI 0.41 to 3.36). The risk of CD was especially pronounced among psoriatics with concomitant psoriatic arthritis (RR, 6.43, 95% CI 2.04 to 20.32).
Conclusions Psoriasis with concomitant psoriatic arthritis is associated with an increased risk of incident CD.

AB Stra6 is the retinoic acid (RA)-inducible gene encoding the cellular receptor for holo-retinol binding protein. This transmembrane protein mediates the internalization of retinol, which then upregulates RA-responsive genes in target cells. Here, we show that Stra6 can be upregulated by DNA damage in a p53-dependent manner, and it has an important role in cell death responses. Stra6 expression induced significant amounts of apoptosis in normal and cancer cells, and it was also able to influence p53-mediated cell fate decisions by turning an initial arrest response into cell death. Moreover, inhibition of Stra6 severely compromised p53-induced apoptosis. We also found that Stra6 induced mitochondria depolarization and accumulation of reactive oxygen species, and that it was present not only at the cellular membrane but also in the cytosol. Finally, we show that these novel functions of Stra6 did not require downstream activation of RA signalling. Our results present a previously unknown link between the RA and p53 pathways and provide a rationale to use retinoids to upregulate Stra6, and thus enhance the tumour suppressor functions of p53. This may have implications for the role of vitamin A metabolites in cancer prevention and treatment.

AB Objective Serum thyroglobulin (Tg) has been associated with a number of thyroid disorders and has been proposed as an indicator of iodine deficiency in a population. However, few studies have addressed the epidemiology of Tg in a population-based setting or in the context of exposure to radioactive iodine-131 (I-131). Our objective was to evaluate baseline levels of Tg in relation to sociodemographic characteristics, iodine status and thyroid function for individuals exposed to I-131. Design A population-based cohort assembled in Belarus following the Chornobyl accident provided demographic factors, clinical data and physiological measurements. Participants Our analytical sample included 10344 subjects of whom 7890 had no thyroid disease and 2454 had evidence of structural or functional thyroid abnormality. Measurements Standardized assays were used to measure serum Tg, urinary iodine, TSH and antibodies to Tg and thyroid peroxidase. Ultrasound was used to assess the presence of nodules and estimate thyroid volume. Results In the fully adjusted model, percent change in Tg was significantly increased among females, smokers and subjects of older age and Tg increased with decreasing urinary iodine concentration, increasing serum TSH and increasing thyroid volume (P-values for trend <0 center dot 0001), and presence of thyroid nodules (P<0 center dot 05). We found a complex interaction between region of residence, rural/urban living, presence/absence of thyroid abnormalities and serum Tg (P<0 center dot 0001). Conclusions In residents of Belarus, serum Tg is significantly related to presence of thyroid abnormalities as well as indicators of thyroid function and iodine deficiency and, therefore, could be used to characterize the iodine status and thyroid function of individuals in the context of epidemiological study.

TI A Review of Current Fixation Use and Registry Outcomes in Total Hip
Arthroplasty: The Uncemented Paradox
SO CLINICAL ORTHOPAEDICS AND RELATED RESEARCH
LA English
DT Review
ID CONCISE FOLLOW-UP; SURVIVORSHIP; MINIMUM; CEMENT
AB The majority (86%) of THAs performed in the United States are uncemented. This may increase the revision burden if uncemented fixation is associated with a higher risk of revision than other approaches.
We sought to investigate trends for use of uncemented fixation and to analyze age-stratified risk of revision comparing cemented, hybrid, and uncemented fixation as reported by national hip arthroplasty registries.
Data were extracted from the annual reports of seven national hip arthroplasty registries; we included all national registries for which annual reports were available in English or a Scandinavian language, if the registry had a history of more than 5 years of data collection.
Current use of uncemented fixation in primary THAs varies between 15% in Sweden and 82% in Canada. From 2006 to 2010 the registries of all countries reported overall increases in the use of uncemented fixation; Sweden reported the smallest absolute increase (from 10% to 15%), and Denmark reported the greatest absolute increase (from 47% to 68%). Looking only at the oldest age groups, use of uncemented fixation also was increasing during the period. In the oldest age group of each of the registries we surveyed (age older than 65 years for England-Wales; age older than 75 years in three registries), cemented fixation was associated with a lower risk of revision than was uncemented fixation.
Increasing use of uncemented fixation in THA is a worldwide phenomenon. This trend is paradoxic, given that registry data, which represent nationwide THA outcomes, suggest that cemented fixation in patients older than 75 years results in the lowest risk of revision.
Level II, systematic review. See Guidelines for Authors for a complete description of levels of evidence.

AB Objective. This survey assessed the in-hospital needs of patients diagnosed with autism spectrum disorders (ASDs). Methods. Parents were recruited to complete a 21-item survey about the needs of their child with an ASD while in the hospital. ASD diagnosis was reported by parents at the time of the survey. The results of the survey were analyzed and evaluated in 3 distinct categories of need. Results. We documented a range of responses associated with ASD-specific needs during hospitalization. Common concerns included child safety and the importance of acknowledging individual communication methods. Conclusions. In a population of children with ASDs, parents report a diverse range of needs while in the hospital. These data support the concept that a pragmatic assessment of individual communication and sensory differences is likely to be essential in the development of an appropriate inpatient care plan.

AB Bmp4 expression is tightly regulated during embryonic tooth development, with early expression in the dental epithelial placode leading to later expression in the dental mesenchyme. Msx1 is among several transcription factors that are induced by epithelial Bmp4 and that, in turn, are necessary for the induction and maintenance of dental mesenchymal Bmp4 expression. Thus, Msx1(-/-) teeth arrest at early bud stage and show loss of Bmp4 expression in the mesenchyme. Ectopic expression of Bmp4 rescues this bud stage arrest. We have identified Tbx2 expression in the dental mesenchyme at bud stage and show that this can be induced by epithelial Bmp4. We also show that endogenous Tbx2 and Msx1 can physically interact in mouse C3H10T1/2 cells. In order to ascertain a functional relationship between Msx1 and Tbx2 in tooth development, we crossed Tbx2 and Msx1 mutant mice. Our data show that the bud stage tooth arrest in Msx1(-/-) mice is partially rescued in Msx1(-/-);Tbx2(+/-) compound mutants. This rescue is accompanied by formation of the enamel knot (EK) and by restoration of mesenchymal Bmp4 expression. Finally, knockdown of Tbx2 in C3H10T1/2 cells results in an increase in Bmp4 expression. Together, these data identify a novel role for Tbx2 in tooth development and suggest that, following their induction by epithelial Bmp4, Msx1 and Tbx2 in turn antagonistically regulate odontogenic activity that leads to EK formation and to mesenchymal Bmp4 expression at the key bud-to-cap stage transition.

AB Aim To determine whether early measures of adaptive behavior are predictive of later school difficulties and achievement in otherwise neurotypical (unimpaired) children with onset of epilepsy during the preschool years. Method In a prospective cohort study, parents completed the Vineland Adaptive Behavior Scales (VABS) for children who were aged 5years or less at epilepsy diagnosis. Eight to 9 years later, the children were assessed using the Wechsler Intelligence Scales for Children (WISC), the Wide Range Achievement Test (WRAT), and the Child Behavior Checklist (CBCL). Associations of VABS scores with later WRAT and CBCL scores were tested. Results A total of 108 neurotypical children (64 males, 44 females; mean age at testing 11y 11mo, SD 2y) were studied. After adjustment for IQ and other factors, there was an increase of 0.15 points (95% confidence interval [CI] 0.03-0.27 points; p=0.03) and 0.14 points (95% CI 0.0-0.28 points; p=0.05) in WRAT reading and spelling scores for each 1-point increment in the VABS communication score. Corresponding numbers for the VABS socialization score were 0.20 (95% CI 0.08-0.32; p=0.005) and 0.17 (95% CI 0.05-0.29; p=0.005). Conclusion In neurotypical preschool children with epilepsy, early social and communication scores predict later school performance. These findings raise questions about opportunities for early identification and intervention for children at greatest risk.

A new study in this issue by Jacobs-Tulleneers-Thevissen et al (doi: 10.1007/s00125-013-2906-0) advances the field by showing that human islets contained in alginate capsules can function very well, not only in the peritoneal cavity of mice, but also in a human with type 1 diabetes. Many obstacles must still be overcome, but this technology has the potential to safely protect transplanted beta cells from autoimmunity and allorejection.

AB Monogenic diabetes (MD) might be misdiagnosed as type 1 diabetes. The prevalence of MD among children with apparent type 1 diabetes has not been established. Our aim was to estimate the prevalence of common forms of MD in childhood diabetes.
We investigated 2,756 children aged 0-14 years with newly diagnosed diabetes who had been recruited to the nationwide population-based Norwegian Childhood Diabetes Registry (NCDR), from July 2002 to March 2012. Completeness of ascertainment was 91%. Children diagnosed with diabetes who were under12 months of age were screened for mutations in KCNJ11, ABCC8 and INS. Children without GAD and protein tyrosine phosphatase-like protein antibodies were screened in two ways. Those who had a parent with diabetes were screened for mutations in HNF1A, HNF4A, INS and MT-TL1. Children with HbA(1c) < 7.5% (< 58 mmol/mol) and no insulin requirement were screened for mutations in GCK. Finally, we searched the Norwegian MODY Registry for children with genetically verified MD.
We identified 15 children harbouring a mutation in HNF1A, nine with one in GCK, four with one in KCNJ11, one child with a mutation in INS and none with a mutation in MT-TL1. The minimum prevalence of MD in the NCDR was therefore 1.1%. By searching the Norwegian MODY Registry, we found 24 children with glucokinase-MODY, 15 of whom were not present in the NCDR. We estimated the minimum prevalence of MD among Norwegian children to be 3.1/100,000.
This is the first prevalence study of the common forms of MD in a nationwide, population-based registry of childhood diabetes. We found that 1.1% of patients in the Norwegian Childhood Diabetes Registry had MD.

AB We investigated whether heterogeneous nuclear ribonucleoproteins F and K (hnRNP F, hnRNP K) mediate insulin inhibition of renal Agt expression and prevention of hypertension and kidney injury in an Akita mouse model of type 1 diabetes.
Adult male Akita mice (12 weeks old) were treated with insulin implants and killed at week 16. Untreated non-Akita littermates served as controls. The effects of insulin on blood glucose, systolic BP (SBP), renal proximal tubular cell (RPTC) gene expression and interstitial fibrosis were studied. We also examined immortalised rat RPTCs stably transfected with control plasmid or with plasmid containing rat Agt promoter in vitro.
Insulin treatment normalised blood glucose levels and SBP, inhibited renal AGT expression but enhanced hnRNP F, hnRNP K and angiotensin-converting enzyme-2 expression, attenuated renal hypertrophy and glomerular hyperfiltration and decreased urinary albumin/creatinine ratio, as well as AGT and angiotensin II levels, in Akita mice. In vitro, insulin inhibited Agt but stimulated Hnrnpf and Hnrnpk expression in high-glucose media via p44/42 mitogen-activated protein kinase signalling in RPTCs. Transfection with Hnrnpf or Hnrnpk small interfering RNAs prevented insulin inhibition of Agt expression in RPTCs.
These data indicate that insulin prevents hypertension and attenuates kidney injury, at least in part, through suppressing renal Agt transcription via upregulation of hnRNP F and hnRNP K expression in diabetic Akita mice. HnRNP F and hnRNP K may be potential targets in the treatment of hypertension and kidney injury in diabetes.

AB Precise characterization of chromatin states is an important but difficult task for understanding the regulatory role of chromatin. A number of computational methods have been developed with varying levels of success. However, a remaining challenge is to model epigenomic patterns over multi-scales, as each histone mark is distributed with its own characteristic length scale. We developed a tiered hidden Markov model and applied it to analyze a ChIP-seq dataset in human embryonic stem cells. We identified a two-tier structure containing 15 distinct bin-level chromatin states grouped into three domain-level states. Whereas the bin-level states capture the local variation of histone marks, the domain-level states detect large-scale variations. Compared to bin-level states, the domain-level states are more robust and coherent. We also found active regions in intergenic regions that upon closer examination were expressed non-coding RNAs and pseudogenes. These results provide insights into an additional layer of complexity in chromatin organization. (C) 2013 Elsevier Inc. All rights reserved.

AB Next-generation sequencing is increasingly employed in biomedical investigations. Strong concordance between microarray and mRNA-seq levels has been reported in high quality specimens but information is lacking on formalin-fixed, paraffin-embedded (FFPE) tissues, and particularly for microRNA (miRNA) analysis. We conducted a preliminary examination of the concordance between miRNA-seq and cDNA-mediated annealing, selection, extension, and ligation (DASL) miRNA assays. Quantitative agreement between platforms is moderate (Spearman correlation 0.514-0.596) and there is discordance of detection calls on a subset of miRNAs. Quantitative PCR (q-RT-PCR) performed for several discordant miRNAs confirmed the presence of most sequences detected by miRNA-seq but not by DASL but also that miRNA-seq did not detect some sequences, which DASL confidently detected. Our results suggest that miRNA-seq is specific, with few false positive calls, but it may not detect certain abundant miRNAs in FFPE tissue. Further work is necessary to fully address these issues that are pertinent for translational research. (C) 2013 Published by Elsevier Inc.

AB Objective Pancreatic cysts are commonly detected in patients undergoing pancreatic imaging. Better approaches are needed to characterise these lesions. In this study we evaluated the utility of detecting mutant DNA in secretin-stimulated pancreatic juice.
Design Secretin-stimulated pancreatic juice was collected from the duodenum of 291 subjects enrolled in Cancer of the Pancreas Screening trials at five US academic medical centres. The study population included subjects with a familial predisposition to pancreatic cancer who underwent pancreatic screening, and disease controls with normal pancreata, chronic pancreatitis, sporadic intraductal papillary mucinous neoplasm (IPMN) or other neoplasms. Somatic GNAS mutations (reported prevalence similar to 66% of IPMNs) were measured using digital high-resolution melt-curve analysis and pyrosequencing.
Results GNAS mutations were detected in secretin-stimulated pancreatic juice samples of 50 of 78 familial and sporadic cases of IPMN(s) (64.1%), 15 of 33 (45.5%) with only diminutive cysts (<5 mm), but none of 57 disease controls. GNAS mutations were also detected in five of 123 screened subjects without a pancreatic cyst. Among 97 subjects who had serial pancreatic evaluations, GNAS mutations detected in baseline juice samples predicted subsequent emergence or increasing size of pancreatic cysts.
Conclusion Duodenal collections of secretin-stimulated pancreatic juice from patients with IPMNs have a similar prevalence of mutant GNAS to primary IPMNs, indicating that these samples are an excellent source of mutant DNA from the pancreas. The detection of GNAS mutations before an IPMN is visible suggests that analysis of pancreatic juice has the potential to help in the risk stratification and surveillance of patients undergoing pancreatic screening.

DT Article
ID EXPRESSION; CD28; B7-1
AB The binding motif of human CTLA-4 is well known to be MYPPPY and for porcine CTLA-4 the binding motif is LYPPPY. Is this single amino acid difference of methionine (M) versus leucine (L) critical for the CTLA-4 binding? Recently, we have reported that the recombinant soluble porcine CTLA-4 was incapable of binding to human CD80. In this study we mutated L to M in the binding motif of the soluble porcine CTLA-4 and mutated M to L in the binding motif of the soluble human CTLA-4. We then analyzed how these mutations affected the binding affinity of the mutants to both porcine and human CD80(+) cells. The soluble porcine CTLA-4-L97M mutant partially lost its binding affinity to porcine CD80 compared to the wild-type and conferred very weak binding ability to human CD80. These results indicate that the L in the binding motif of porcine CTLA-4 is important for determining its binding ability to porcine CD80. Wild-type soluble human CTLA-4 binds to both human and porcine CD80 with comparable affinity, however, the soluble human CTLA-4-M97L mutant almost lost its binding ability to human CD80 and increased its binding ability to porcine CD80. These results indicate that M in the human CTLA-4 binding motif is extremely critical for its binding to human CD80. Those data suggest that the human CTLA-4 based recombinant protein drugs such as human CTLA-4-Ig can be used and/or tested in a porcine model. Conversely, the use of porcine CTLA-4 based recombinant protein drugs such as porcine CTLA-4-Ig is restricted to swine models. The difference in binding specificity of CTLA-4 observed in this study may be useful for studies such as pig to nonhuman primate xeno-transplantation. Porcine CTLA-4- and human CTLA-4-M97L mutant-based recombinant protein drugs can be used to specifically block the direct presentation by donor antigen presenting cells in pig to nonhuman primate xeno-transplantation. Human CTLA-4-M97L mutant-based recombinant protein drugs will be more ideal as it is without immunogenicity to human being. (c) 2013 American Society for Histocompatibility and Immunogenetics.

AB Environmental factors including ionizing radiation and chemical agents have been known to be able to induce DNA rearrangements and cause genomic structural variations (SVs); however, the roles of intrinsic characteristics of the human genome, such as regional genome architecture, in SV formation and the potential mechanisms underlying genomic instability remain to be further elucidated. Recently, locus-specific observations showed that self-chain (SC), a group of short low-copy repeats (LCRs) in the human genome, can induce autism-associated SV mutations of the MECP2 and NRXN1 genes. In this study, we conducted a genome-wide analysis to investigate SCs and their potential roles in genomic SV formation. Utilizing a vast amount of human SV data, we observed a significant biased distribution of human germline SV breakpoints to SC regions. Notably, the breakpoint distribution pattern is different between SV types across deletion, duplication, inversion and insertion. Our observations were coincident with a mechanism of SC-induced DNA replicative errors, whereas SC may sporadically be used as substrates of nonallelic homologous recombination (NAHR). This contention was further supported by our consistent findings in somatic SV mutations of cancer genomes, suggesting a general mechanism of SC-induced genome instability in human germ and somatic cells.

AB The pubertal height growth spurt is a distinctive feature of childhood growth reflecting both the central onset of puberty and local growth factors. Although little is known about the underlying genetics, growth variability during puberty correlates with adult risks for hormone-dependent cancer and adverse cardiometabolic health. The only gene so far associated with pubertal height growth, LIN28B, pleiotropically influences childhood growth, puberty and cancer progression, pointing to shared underlying mechanisms. To discover genetic loci influencing pubertal height and growth and to place them in context of overall growth and maturation, we performed genome-wide association meta-analyses in 18 737 European samples utilizing longitudinally collected height measurements. We found significant associations (P 1.67 10(8)) at 10 loci, including LIN28B. Five loci associated with pubertal timing, all impacting multiple aspects of growth. In particular, a novel variant correlated with expression of MAPK3, and associated both with increased prepubertal growth and earlier menarche. Another variant near ADCY3-POMC associated with increased body mass index, reduced pubertal growth and earlier puberty. Whereas epidemiological correlations suggest that early puberty marks a pathway from rapid prepubertal growth to reduced final height and adult obesity, our study shows that individual loci associating with pubertal growth have variable longitudinal growth patterns that may differ from epidemiological observations. Overall, this study uncovers part of the complex genetic architecture linking pubertal height growth, the timing of puberty and childhood obesity and provides new information to pinpoint processes linking these traits.

AB Silymarin displays anti-inflammatory effects on T lymphocytes in vitro. The immunomodulatory properties of oral silymarin in vivo in humans with chronic hepatitis C have not previously been characterized. We hypothesized that silymarin would suppress T-cell proliferation and pro-inflammatory cytokine production of virus- and non-virus-specific T cells while increasing anti-inflammatory IL-10 production in vivo. Patients from one site of the SyNCH-HCV double-masked, placebo-controlled study of oral silymarin in prior interferon nonresponders with chronic hepatitis C provided blood samples at baseline and treatment week 20. Mononuclear cells were stimulated with recombinant HCV proteins and controls in 3H-thymidine proliferation assays, IFN ELISPOT and IL-10 ELISPOT. The frequency of CD4+CD25hi and CD4+foxp3+ regulatory T cells, serum cytokine levels, serum IP-10 and lymphocyte interferon-stimulated gene expression were also quantified at baseline and week 20. Thirty-two patients were recruited (10; placebo, 11; 420mg three times a day, 11; 700mg three times a day). Serum ALT and HCV RNA titres did not change in any group. HCV-specific CD4+ T-cell proliferation and the frequency of IFN- and IL-10-producing T cells were not significantly changed in silymarin-treated subjects. However, C.albicans-induced T-cell IFN and phytohaemagglutinin-induced T-cell proliferation were suppressed by silymarin therapy. A trend towards augmentation of interferon-induced ISG15 expression was present in the high-dose silymarin group. While no effect on HCV-specific T cells was identified, these data confirm that high-dose oral silymarin exerts modest nonspecific immunomodulatory effects in vivo. The impact of this anti-inflammatory effect on long-term liver health in chronic hepatitis C merits future clinical investigation.

AB Cigarette smoking leads to upregulation of brain nicotinic acetylcholine receptors (nAChRs), including the common alpha(4)beta(2)* nAChR subtype. Although a substantial percentage of smokers receive treatment for tobacco dependence with counseling and/or medication, the effect of a standard course of these treatments on nAChR upregulation has not yet been reported. In the present study, 48 otherwise healthy smokers underwent positron emission tomography (PET) scanning with the radiotracer 2-FA (for labeling alpha(4)beta(2)* nAChRs) before and after treatment with either cognitive-behavioral therapy, bupropion HCl, or pill placebo. Specific binding volume of distribution (VS/fP), a measure proportional to a4b2* nAChR density, was determined for regions known to have nAChR upregulation with smoking (prefrontal cortex, brainstem, and cerebellum). In the overall study sample, significant decreases in VS/fP were found for the prefrontal cortex, brainstem, and cerebellum of -20 (+/- 35), -25 (+/- 36), and -25 (+/- 31)%, respectively, which represented movement of VS/fP values toward values found in non-smokers (mean 58.2% normalization of receptor levels). Participants who quit smoking had significantly greater reductions in VS/fP across regions than non-quitters, and correlations were found between reductions in cigarettes per day and decreases in VS/fP for brainstem and cerebellum, but there was no between-group effect of treatment type. Thus, smoking reduction and cessation with commonly used treatments (and pill placebo) lead to decreased alpha(4)beta(2)* nAChR densities across brain regions. Study findings could prove useful in the treatment of smokers by providing encouragement with the knowledge that decreased smoking leads to normalization of specific brain receptors.

AB Dr. John J. Jack' Downes (1930-), the anesthesiologist-in-chief at The Children's Hospital of Philadelphia (1972-1996), has made numerous contributions to pediatric anesthesia and critical care medicine through a broad spectrum of research on chronic respiratory failure, status asthmaticus, postoperative risks of apnea in premature infants, and home-assisted mechanical ventilation. However, his defining moment was in January 1967, when The Children's Hospital of Philadelphia inaugurated its pediatric intensive care unitthe first of its kind in North America. During his tenure, he and his colleagues trained an entire generation of pediatric anesthesiologists and intensivists and set a standard of care and professionalism that continues to the present day. Based on an interview with Dr. Downes, this article reviews a career that advanced pediatric anesthesia and critical care medicine and describes the development of that first pediatric intensive care unit at The Children's Hospital of Philadelphia.

AB Considerable progress has been made in our understanding of the biological basis for cancer therapy-induced mucosal barrier injury (mucositis). The last formal review of the subject by MASCC/ISOO was published in 2007; consequently, an update is timely.
Panel members reviewed the biomedical literature on mucositis pathobiology published between January 2005 and December 2011.
Recent research has provided data on the contribution of tissue structure changes, inflammation and microbiome changes to the development of mucositis. Additional research has focused on targeted therapy-induced toxicity, toxicity clustering and the investigation of genetic polymorphisms in toxicity prediction. This review paper summarizes the recent evidence on these aspects of mucositis pathobiology.
The ultimate goal of mucositis researchers is to identify the most appropriate targets for therapeutic interventions and to be able to predict toxicity risk and personalize interventions to genetically suitable patients. Continuing research efforts are needed to further our understanding of mucositis pathobiology and the pharmacogenomics of toxicity.

AB Purpose of review
Lung cancer is the leading cause of cancer mortality in men and women. Most patients present with advanced disease and face significant morbidity, with many reporting distressing symptoms throughout the course of their illness. The purpose of this review is to highlight the recent studies that support the integration of early palliative care into the standard oncology care of patients with advanced lung cancer.
Recent findings
Historically, palliative care was provided predominantly as a hospital-based consultation service; however, recent data support an outpatient delivery model of early palliative care alongside standard oncology care. In two randomized controlled trials, patients with advanced cancer who were assigned to early palliative care reported improved quality of life and mood. Numerous organizations have published guidelines to support the integration of palliative care into the routine care of patients with lung cancer.
Summary
Palliative care is appropriate for patients at any point in a serious illness. Unlike hospice, palliative care is not limited by prognosis and may be provided at the same time as disease-directed therapies. There is strong evidence underscoring the importance of integrating palliative care across the trajectory of lung cancer. The primary oncology team should routinely assess for pain and other symptoms, and regularly inquire about a patient's understanding of his disease and his goals of care. Specialty palliative care can provide an extra layer of support for patients with lung cancer and their families by helping with more challenging symptom management, psychosocial support, complex decision-making, advance care planning, and transitions in care.

AB Purpose of review
Pneumothorax, a potentially life-threatening condition, is present in about one-third of chest trauma patients. Traditionally, pneumothorax has been diagnosed and managed by use of chest radiography, which has been found inaccurate and inconsistent. With the ubiquitous application of multidetector computed tomography (MDCT) in emergency care, MDCT quantification of pneumothoraces becomes an emerging technique for accurate determination of the size of pneumothoraces. The use of MDCT quantification provides a promising means to improve pneumothorax management.
Recent findings
Recent studies have demonstrated that MDCT is the gold standard for detecting pneumothorax and MDCT provides an effective imaging modality for the accurate measurement of the volume of pneumothoraces. The use of MDCT volumetric quantification of pneumothoraces has been evidenced in the improvement of performance in pneumothorax management for clinically stable chest trauma patients.
Summary
The MDCT volumetric quantification of pneumothoraces is a new concept in the care of chest trauma patients and has the potential to improve pneumothorax management. Further clinical studies are needed to establish a MDCT-based clinical guideline for pneumothorax management.

AB Advanced oxidation protein products (AOPPs) are formed during chronic oxidative stress as a result of reactions between plasma proteins and chlorinated oxidants. Their levels are elevated during various cardiovascular diseases. Because elevated AOPPs serve as independent risk factors for ischemic heart disease, and cardiomyocyte death is a hallmark of ischemic heart disease, we hypothesized that AOPPs will induce cardiomyocyte death. AOPP-modified mouse serum albumin (AOPP-MSA) induced significant death of neonatal mouse cardiomyocytes that was attenuated by knockdown of the receptor for advanced glycation end products, but not CD36. Notably, TRAF3-interacting protein 2 (TRAF3IP2; also known as CIKS or Act1) knockdown blunted AOPP-induced apoptosis. AOPP-MSA stimulated Nox2/Rac1-dependent superoxide generation, TRAF3IP2 expression, and TRAF3IP2-dependent JNK activation. The superoxide anion generating xanthine/xanthine oxidase system and hydrogen peroxide both induced TRAF3IP2 expression. Further, AOPP-MSA induced mitochondrial Bax translocation and release of cytochrome c into cytoplasm. Moreover, AOPP-MSA suppressed antiapoptotic Bcl-2 and Bcl-xL expression. These effects were reversed by TRAF3IP2 knockdown or forced expression of mutant JNK. Similar to its effects in neonatal cardiomyocytes, AOPP-MSA induced adult cardiomyocyte death in part via TRAF3IP2. These results demonstrate for the first time that AOPPs induce cardiomyocyte death via Nox2/Rac1/superoxide-dependent TRAF3IP2/JNK activation in vitro and suggest that AOPPs may contribute to myocardial injury in vivo. Thus TRAF3IP2 may represent a potential therapeutic target in ischemic heart disease. (C) 2013 Elsevier Inc. All rights reserved.

AB Dietary restriction is a powerful aging intervention that extends the life span of diverse biological species ranging from yeast to invertebrates to mammals, and it has been argued that the antiaging action of dietary restriction occurs through reduced oxidative stress/damage. Using Sod1(-/-) mice, which have previously been shown to have increased levels of oxidative stress associated with a shorter life span and a high incidence of neoplasia, we were able to test directly the ability of dietary restriction to reverse an aging phenotype due to increased oxidative stress/damage. We found that dietary restriction increased the life span of Sod1(-/-) mice 30%, returning it to that of wild-type, control mice fed ad libitum. Oxidative damage in Sod1(-/-) mice was markedly reduced by dietary restriction, as indicated by a reduction in liver and brain F-2-isoprostanes, a marker of lipid peroxidation. Analysis of end of life pathology showed that dietary restriction significantly reduced the overall incidence of pathological lesions in the Sod1(-/-) mice fed the dietary-restricted diet compared to Sod1(-/-) mice fed ad libitum, including the incidence of lymphoma (27 vs 5%) and overall liver pathology. In addition to reduced incidence of overall and liver-specific pathology, the burden and severity of both neoplastic and nonneoplastic lesions was also significantly reduced in the Sod1(-/-) mice fed the dietary-restricted diet. These data demonstrate that dietary restriction can significantly attenuate the accelerated aging phenotype observed in Sod1(-/-) mice that arises from increased oxidative stress/damage.
