Huntington's disease is a dominantly inherited neurodegenerative disease caused by the expansion of a CAG repeat in the HTT gene. In addition to the length of the CAG expansion, factors such as genetic background have been shown to contribute to the age at onset of neurological symptoms. A central challenge in understanding the disease progression that leads from the HD mutation to massive cell death in the striatum is the ability to characterize the subtle and early functional consequences of the CAG expansion longitudinally...

PURPOSE: Bladder preservation therapy is an effective treatment for muscle-invasive urothelial carcinoma (UC). In this study we treated noncystectomy candidates with daily radiation and weekly paclitaxel for 7 weeks. Patients whose tumors showed her2/neu overexpression were additionally treated with weekly trastuzumab. METHODS AND MATERIALS: Sixty-eight evaluable patients were treated with radiation therapy and either paclitaxel + trastuzumab (group 1) or paclitaxel alone (group 2)...

Plasma kynurenine/tryptophan (KT) ratio, a marker of adaptive immune defects, strongly predicts mortality during treated HIV disease in Ugandans compared to U.S.-based populations, Here, KT ratio, and T cell and plasma biomarkers of immune activation were measured among 535 HIV-infected Ugandans prior to ART initiation and at month 6 of viral suppression. Month 6 KT ratio (aHR=2.74), sCD14 (aHR=2.32), IL-6 (aHR=2.34), and D dimer (aHR=1.95) were associated with mortality occurring ≥6 months after ART initiation, KT ratio remained significantly predictive of mortality even after adjustment for the additional biomarkers, suggesting an independent contribution to clinical outcomes in resource-limited settings...

Nearly a quarter of older adults in the U.S. have type 2 diabetes, and this population is continuing to increase with the aging of the population. Older adults are at high risk for the development of type 2 diabetes due to the combined effects of genetic, lifestyle, and aging influences. The usual defects contributing to type 2 diabetes are further complicated by the natural physiological changes associated with aging as well as the comorbidities and functional impairments that are often present in older people...

The prognostic improvement attributed to genetic markers over current prognostic system has not been well studied for melanoma. The goal of this study is to evaluate the added prognostic value of Vitamin D Pathway (VitD) SNPs to currently known clinical and demographic factors such as age, sex, Breslow thickness, mitosis and ulceration (CDF). We utilized two large independent well-characterized melanoma studies: the Genes, Environment, and Melanoma (GEM) and MD Anderson studies, and performed variable selection of VitD pathway SNPs and CDF using Random Survival Forest (RSF) method in addition to Cox proportional hazards models...

Orthomyxoviruses are an important family of RNA viruses, which include the various influenza viruses. Despite global efforts to eradicate orthomyxoviral pathogens, these infections remain pervasive. One such orthomyxovirus, infectious salmon anemia virus (ISAV), spreads easily throughout farmed and wild salmonids, constituting a significant economic burden. ISAV entry requires the interplay of the virion-attached hemagglutinin-esterase and fusion glycoproteins. Preventing infections will rely on improved understanding of ISAV entry...

Promoter elements play important roles in isoform and cell-type specific expression. We surveyed the epigenomic promoter landscape of gastric adenocarcinoma (GC), analyzing 110 chromatin profiles (H3K4me3, H3K4me1, H3K27ac) of primary GCs, GC lines, and non-malignant gastric tissues. We identified ~2000 promoter alterations (somatic promoters), many deregulated in various epithelial malignancies and mapping frequently to alternative promoters within the same gene, generating potential pro-oncogenic isoforms (RASA3)...

Urea removal has become a key measure of the intensity of dialysis treatment for kidney failure. Small solute removal, exemplified by Kt/Vurea, has been broadly applied as a means to quantify the dose of thrice weekly hemodialysis. Yet, the reliance on small solute clearances alone as a measure of dialysis adequacy fails fully to quantify the intended clinical effects of dialysis therapy. This review aims to (1) understand the strengths and limitations of small solute kinetics as a surrogate marker of dialysis dose, and (2) present the prospect of a more comprehensive construct for dialysis dose, one that considers more broadly the goals of ESRD care to maximize both quality of life and survival...

Docosahexaenoic acid (DHA), a polyunsaturated fatty acid (PUFA) enriched in phospholipids in the brain and retina, is known to play multi-functional roles in brain health and diseases. While arachidonic acid (AA) is released from membrane phospholipids by cytosolic phospholipase A2 (cPLA2), DHA is linked to action of the Ca(2+)-independent iPLA2. DHA undergoes enzymatic conversion by 15-lipoxygenase (Alox 15) to form oxylipins including resolvins and neuroprotectins, which are powerful lipid mediators. DHA can also undergo non-enzymatic conversion by reacting with oxygen free radicals (ROS), which cause the production of 4-hydoxyhexenal (4-HHE), an aldehyde derivative which can form adducts with DNA, proteins and lipids...

Background Although transcatheter aortic-valve replacement (TAVR) is an accepted alternative to surgery in patients with severe aortic stenosis who are at high surgical risk, less is known about comparative outcomes among patients with aortic stenosis who are at intermediate surgical risk. Methods We evaluated the clinical outcomes in intermediate-risk patients with severe, symptomatic aortic stenosis in a randomized trial comparing TAVR (performed with the use of a self-expanding prosthesis) with surgical aortic-valve replacement...

OBJECTIVE: Risk factors for postpartum depression in euthymic pregnant women with histories of major depressive disorder (MDD) were evaluated. METHODS: From April 2003 to March 2009, 343 pregnant women with a history of Structured Clinical Interview for DSM-IV (SCID)-diagnosed major depressive disorder were prospectively assessed from the third trimester into the postpartum period using the SCID mood module and 17-item Hamilton Depression Rating Scale (HDRS). Data from 300 subjects who completed at least 2 mood module assessments (1 within 60 days before and the other within 60 days after delivery) were analyzed for predictive associations between variables assessed in the third trimester and the development of a postpartum depression...

OBJECTIVES: Efficient use of nivolumab in non-small-cell lung cancer (NSCLC) has been limited by the lack of a definitive predictive biomarker. In patients with metastatic melanoma treated with ipilimumab, a pretreatment neutrophil-to-lymphocyte ratio (NLR)<5 has been associated with improved survival. This retrospective cohort study aimed to determine whether the pretreatment NLR was associated with outcomes in NSCLC patients treated with nivolumab. METHODS: We reviewed the medical records of all patients with previously treated advanced NSCLC who received nivolumab between March 2015 and March 2016 outside of a clinical trial at the University of Pennsylvania...
