OBJECTIVES: We investigate the effect of immediate ART eligibility on HIV incidence among HIV-uninfected household members. DESIGN: Regression discontinuity study arising from a population-based cohort. METHODS: Household members of patients seeking care at the Hlabisa HIV Treatment and Care Programme in rural KwaZulu-Natal South Africa between January 2007 and August 2011 with CD4 counts up to 350 cells/μl were eligible for inclusion if they had at least two HIV tests and were HIV-uninfected at the time the index patient linked to care (N = 4,115)...

BACKGROUND: The prevalence of breast cancer in Iran has increased. An effective approach to decrease the burden of breast cancer is prevention. OBJECTIVE: The aim of this study was to develop and evaluate an educational model, called the ASSISTS, for promoting breast cancer-preventive behaviors in women. METHODS: A multiphase method was used to develop the model designed to promote breast cancer prevention behaviors. A conceptual model was generated based on a secondary analysis of qualitative data...

Global increases in coral disease prevalence have been linked to ocean warming through changes in coral-associated bacterial communities, pathogen virulence and immune system function. However, the interactive effects of temperature and pathogens on the coral holobiont are poorly understood. Here, we assessed three compartments of the holobiont (host, Symbiodinium, bacterial community) of the coral Montipora aequituberculata challenged with the pathogen Vibrio coralliilyticus and the commensal bacterium Oceanospirillales sp...

PDGFβ receptors and their ligand, PDGF-BB, are upregulated in vivo after neuronal insults such as ischemia. When applied exogenously, PDGF-BB is neuroprotective against excitotoxicity and HIV proteins. METHODS: Given this growth factor's neuroprotective ability, we sought to determine if PDGF-BB would be neuroprotective against amyloid-β (1-42), one of the pathological agents associated with Alzheimer's disease (AD). In both primary hippocampal neurons and the human-derived neuroblastoma cell line, SH-SY5Y, amyloid- treatment for 24 h decreased surviving cell number in a concentration-dependent manner...

Context • One of the most common complications of a Caesarean section (C-section) is postoperative inflammation as well as operative and postoperative pain associated with the surgery. The control and mitigation of pain after surgery is the main goal of anesthesiologists. Objectives • This study aimed to compare the effects of intravenous apotel and remifentanil on postoperative pain control in women undergoing an elective C-section. Design • The research team designed a single-blinded, randomized clinical trial...

Shear wave elasticity imaging (SWEI) is a novel ultrasound elastography technique for assessing tissue stiffness. In this study, we investigate the potential of SWEI for providing diastolic functional assessment. In 11 isolated rabbit hearts, pressure-volume (PV) measurements were recorded simultaneously with SWEI recordings from the left ventricle free wall before and after induction of global ischemia. PV-based end diastolic stiffness increased by 100% after ischemia (p <0.05), and SWEI stiffness showed an increase of 103% (p <0...

INTRODUCTION: Although several trials have assessed the effect of coenzyme Q10 (CoQ10) supplementation on blood pressures among patients with metabolic diseases, findings are controversial. AIM: This review of randomized controlled trials (RCTs) was performed to summarize the evidence on the effects of CoQ10 supplementation on blood pressures among patients with metabolic diseases. METHODS: Randomized-controlled trials (RCTs) published in PubMed, EMBASE, Web of Science and Cochrane Library databases up to 10 August 2017 were searched...

Cluster analysis and other subgrouping techniques have risen in popularity in recent years in non-invasive brain stimulation research in the attempt to investigate the issue of inter-individual variability - the issue of why some individuals respond, as traditionally expected, to non-invasive brain stimulation protocols and others do not. Cluster analysis and subgrouping techniques have been used to categorise individuals, based on their response patterns, as responder or non-responders. There is, however, a lack of consensus and consistency on the most appropriate technique to use...

BACKGROUND: Neonatal diabetes mellitus (NDM) is a rare disorder worldwide where diabetes is diagnosed in the first 6 months of life. However, Oman has a relatively high incidence of NDM. METHODS: In this study, we investigated the genetic etiologies underlying NDM and their prevalence in Oman. We collected a cohort of 24 NDM patients, with and without genetic diagnosis, referred to our center from 2007 to 2015. All patients without a genetic diagnosis were tested for mutations in 23 NDM-associated genes using a custom-targeted next-generation sequencing (NGS) panel and methylation analysis of the 6q24 locus...

Omega-3 fatty acid (FA) supplementation has been reported to improve several cardio-metabolic risk factors. We aimed to assess the efficacy of omega-3 fatty acids on metabolic and inflammatory indices in patients with schizophrenia who were taking clozapine and sodium valproate. All patients were on a stable dose of 300-400mg of clozapine for 3 months. Subjects were randomized to treatment with either omega-3 fatty acid (4gr/day) or a placebo for 8 weeks. Height, weight, abdominal circumference, serum lipid profile, fasting blood glucose (FBG), and serum high sensitivity-C-reactive protein (hs-CRP) were determined at baseline and after 8 weeks of treatment...

Polymorphisms in the cytochrome P (CYP) 450 family may cause adverse drug responses in individuals. Cytochrome P450 2C19 (CYP2C19) is a member of the CYP family, where the presence of the 681 G>A, 636 G>A and 806 C>T polymorphisms result in the CYP2C19*2, CYP2C19*3 and CYP2C19*17 alleles, respectively. In the current study, the frequency of the CYP2C19*2, CYP2C19*3 and CYP2C19*17 alleles in an Iranian population cohort of different ethnicities were examined and then compared with previously published frequencies within other populations...

The influence of polymer aging, water pH, and aqueous Pb concentration on Pb deposition onto low density polyethylene (LDPE) was investigated. LDPE pellets were aged by ozonation at 85 °C. ATR-FTIR and X-ray photoelectron spectroscopy (XPS) analysis of aged LDPE surfaces showed that a variety of polar functional groups (>CO<, >CO, >COO) were formed during aging. These functional groups likely provided better nucleation sites for Pb(OH)2 deposition compared to new LDPE, which did not have these oxygen-containing functional groups...

PURPOSE: To see whether applying four different liners under short fiber-reinforced composite (SFRC), everX Posterior, compared to conventional composite resin, Z250, affected their strengthening property in premolar MOD cavities. MATERIALS AND METHODS: Mesio-occluso-distal (MOD) cavities were prepared in 120 sound maxillary premolars divided into 10 groups (n = 12) in terms of two composite resin types and 4 liners or no liner. For each composite resin, in 5 groups no liner, resin-modified glass ionomer (RMGI), conventional flowable composite (COFL), self-adhesive flowable composite resin (SAFL), and self-adhesive resin cement (SARC) were applied prior to restoring incrementally...

Thoracic aortocaval fistula is a very rare cause of left to right shunt. Drainage of fistula into the superior vena cava (SVC) is very uncommon. Clinical symptoms depend on the size of the shunt. We report a rare case of an asymptomatic 27-year-old woman with congenital aortocaval fistula to the SVC with a small amount of left to right shunt that was considered for serial medical follow-up.

Understanding of electrical double layers is essential to all electrochemical devices, particularly at high charge carrier concentrations. Using a combined approach (surface force apparatus, Zeta potential, infrared spectroscopy), we propose a model for the interfacial structure of triglyme electrolytes on muscovite Mica. In contact with the pure triglyme, a brush-like polymeric structure grows on the Mica surface. When lithium triflate is present in the triglyme, this structure is suppressed by anion adsorption and an extended double layer is formed...
