Molecular epidemiology can help clarify the properties and dynamics of HIV-1 transmission networks in both global and regional scales. We studied 143 HIV-1-infected individuals recruited from four medical centers of three cities in South Korea between April 2013 and May 2014. HIV-1 env V3 sequence data were generated (337-793 bp) and analyzed using a pairwise distance-based clustering approach to infer putative transmission networks. Participants whose viruses were ≤2.0% divergent according to Tamura-Nei 93 genetic distance were defined as clustering...

Purpose The goals of immediate postmastectomy breast reconstruction are to minimize deformity and optimize quality of life as perceived by patients. We prospectively evaluated patient-reported outcomes (PROs) in women undergoing immediate implant-based or autologous reconstruction. Methods Women undergoing immediate postmastectomy reconstruction for invasive cancer and/or carcinoma in situ were enrolled at 11 sites. Women underwent implant-based or autologous tissue reconstruction. Patients completed the BREAST-Q, a condition-specific PRO measure for breast surgery patients, and Patient-Reported Outcomes Measurement Information System-29, a generic PRO measure, before and 1 year after surgery...

Converting a congested High Occupancy Vehicle (HOV) lane into a High Occupancy Toll (HOT) lane is a viable option for improving travel time reliability for carpools and buses that use the managed lane. However, the emission impacts of HOV-to-HOT-conversions are not well understood. The lack of emissions impact quantification for HOT conversions creates a policy challenge for agencies making transportation funding choices. The goal of this paper is to evaluate the case study before-and-after changes in vehicle emissions for the Atlanta, GA I-85 HOV/HOT lane conversion project, implemented in October, 2011...

In the randomized, controlled study Probiotics in the Prevention of Allergy among Children in Trondheim (ProPACT), maternal probiotic supplementation reduced the incidence of atopic dermatitis (AD) in the offspring. In the current study, we hypothesized that the effect was mediated by a shift in the T helper (Th) cells in the children. OBJECTIVE: To examine whether Th cell proportions were affected by maternal probiotic supplementation and thus could mediate the preventive effect of probiotics on AD...

INTRODUCTION: Low intensity focused ultrasound has recently been identified as a novel method of stimulating targeted neurons. We hypothesized that ultrasound stimulation of the posterior tibial nerve would inhibit bladder contractions in an established rat model of rhythmic bladder contractions. METHODS: Cyclical detrusor contractions were initiated by placing a transurethral catheter in female rats and infusing saline into the bladder. Transcutaneous ultrasound pulses were then delivered to the lower extremity of a rat (overlying the posterior tibial nerve) using a single element spherically focused 250 kHz transducer...

BACKGROUND AND OBJECTIVES: High-quality family medicine education is needed in sub-Saharan Africa to facilitate the future growth of primary care health systems. Current faculty educators recognize the value of dedicated teacher training and ongoing faculty development. However, they are constrained by inadequate faculty development program availability and institutional support. METHODS: A cross-sectional study design was used to conduct a qualitative needs assessment comprised of 37 in-depth, semi-structured interviews of individual faculty trainers from postgraduate family medicine training programs in eight sub-Saharan African countries...

Importance: As perinatally human immunodeficiency virus-infected youth (PHIVY) in the United States grow older and more treatment experienced, clinicians need updated information about the association of age, CD4 cell count, viral load (VL), and antiretroviral (ARV) drug use with risk of opportunistic infections, key clinical events, and mortality to understand patient risks and improve care. Objective: To examine the incidence or first occurrence during follow-up of key clinical events (including Centers for Disease Control and Prevention stage B [CDC-B] and stage C [CDC-C] events) and mortality among PHIVY stratified by age, CD4 cell count, and VL and ARV status...

Proteomics techniques can identify thousands of phosphorylation sites in a single experiment, the majority of which are new and lack precise information about function or molecular mechanism. Here we present a fast method to predict potential phosphorylation switches by mapping phosphorylation sites to protein-protein interactions of known structure and analysing the properties of the protein interface. We predict 1024 sites that could potentially enable or disable particular interactions. We tested a selection of these switches and showed that phosphomimetic mutations indeed affect interactions...

BACKGROUND: Substantial complication rates after postmastectomy breast reconstruction (BR) in breast cancer patients have been reported. Few studies have reported on the resulting psychological distress (PD) and satisfaction with the aesthetic result in relation to postoperative complications after completion of implant or DIEP flap BR. The present study investigated whether women were able to recover from complication related distress in the long term. METHODS: PD was prospectively measured using questionnaires regarding anxiety, depression and cancer distress...

Schinzel-Giedion syndrome (SGS) is a rare developmental disorder characterized by multiple malformations, severe neurological alterations and increased risk of malignancy. SGS is caused by de novo germline mutations clustering to a 12bp hotspot in exon 4 of SETBP1. Mutations in this hotspot disrupt a degron, a signal for the regulation of protein degradation, and lead to the accumulation of SETBP1 protein. Overlapping SETBP1 hotspot mutations have been observed recurrently as somatic events in leukemia. We collected clinical information of 47 SGS patients (including 26 novel cases) with germline SETBP1 mutations and of four individuals with a milder phenotype caused by de novo germline mutations adjacent to the SETBP1 hotspot...

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC...

Gut dysbiosis might underlie the pathogenesis of type 1 diabetes. In mice of the non-obese diabetic (NOD) strain, we found that key features of disease correlated inversely with blood and fecal concentrations of the microbial metabolites acetate and butyrate. We therefore fed NOD mice specialized diets designed to release large amounts of acetate or butyrate after bacterial fermentation in the colon. Each diet provided a high degree of protection from diabetes, even when administered after breakdown of immunotolerance...

Zebrafish embryo assays are increasingly used in the toxicological assessment of endocrine disruptors. Among other advantages, these models are 3R-compliant and are fit for screening purposes. Biotransformation processes are well-recognized as a critical factor influencing toxic response, but major gaps of knowledge exist regarding the characterization of functional metabolic capacities expressed in zebrafish. Comparative metabolic studies between embryos and adults are even scarcer. Using ³H-labeled chemicals, we examined the fate of two estrogenic emerging contaminants, benzophenone-2 (BP2) and bisphenol S (BPS), in 4-day embryos and adult zebrafish...

BACKGROUND: There is growing interest in immune therapies to clear the latent HIV-1 after combination antiretroviral therapy (cART). There is limited information on the effect of cART on antibody-dependent cellular cytotoxicity (ADCC) and no studies have directly compared ADCC in HIV-1 subtype B- and subtype C-infected subjects. The effect of improving immunocompetence on ADCC to influenza also remains unexplored. METHODS: The effect of cART on HIV-1- and influenza-specific ADCC was analyzed in two cohorts (39 subtype B- and 47 subtype C-infected subjects) before and after two years of cART...

The purpose of this study was to create information models from flowsheet data using a data-driven consensus-based method. Electronic health records contain a large volume of data about patient assessments and interventions captured in flowsheets that measure the same "thing," but the names of these observations often differ, according to who performs documentation or the location of the service (eg, pulse rate in an intensive care, the emergency department, or a surgical unit documented by a nurse or therapist or captured by automated monitoring)...

Mature B cell pools retain a substantial proportion of polyreactive and self-reactive clonotypes, suggesting that activation checkpoints exist to reduce the initiation of autoreactive B cell responses. Here, we have described a relationship among the B cell receptor (BCR), TLR9, and cytokine signals that regulate B cell responses to DNA-containing antigens. In both mouse and human B cells, BCR ligands that deliver a TLR9 agonist induce an initial proliferative burst that is followed by apoptotic death. The latter mechanism involves p38-dependent G1 cell-cycle arrest and subsequent intrinsic mitochondrial apoptosis and is shared by all preimmune murine B cell subsets and CD27- human B cells...
