The relevance of gene mutations leading to heart diseases and hence heart failure has become evident. The risk for and the course of heart failure depends on genomic variants and mutations underlying the so-called genetic predisposition. Genetic contribution to heart failure is highly heterogenous and complex. For any patient with a likely inherited heart failure syndrome, genetic counselling is recommended and important. In the last few years, novel sequencing technologies (named next-generation sequencing - NGS) have dramatically improved the availability of molecular testing, the efficiency of genetic analyses, and moreover reduced the cost for genetic testing...

INTRODUCTION: Female sex workers (FSWs) are at high-risk for HIV acquisition in South Africa, where the advent of new HIV prevention and treatment interventions represent the potential to significantly impact the epidemic. This paper focuses on aspects of PrEP acceptability as a new intervention within the context of a larger service delivery programme including the simultaneous rollout of early ART. This paper explores PrEP acceptability among the FGD participants as future potential users...

A mini-fluidic vacuum ultraviolet/ultraviolet (VUV/UV) photoreaction system (MVPS) was developed in our previous study. Based on the MVPS, a green method to determine VUV fluence rate has been developed using the production rate of H2 O2 when water is exposed to 185 nm VUV. The H2 O2 production followed pseudo-zero-order reaction kinetics well over the first 10 min of VUV/UV exposure. This new method was well calibrated with a standard cis-cyclooctene cis-trans photoisomerization actinometer as recommended by the International Union of Pure and Applied Chemistry...

In 2011, the Committee on Nutrition of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition systematically reviewed published evidence related to the safety and health effects of the administration of formulae supplemented with pro- and/or prebiotics compared with unsupplemented formulae. We updated evidence on the effects of the administration of prebiotic-supplemented infant formulae (IF) compared with unsupplemented IF. Five databases were searched up to March 2017 for randomised controlled trials...

New techniques for the genetic modification of organisms are creating new strategies for addressing persistent public health challenges. For example, the company Oxitec has conducted field trials internationally-and has attempted to conduct field trials in the United States-of a genetically modified mosquito that can be used to control dengue, Zika, and some other mosquito-borne diseases. In 2016, a report commissioned by the National Academies of Sciences, Engineering, and Medicine discussed the potential benefits and risks of another strategy, using gene drives...

BACKGROUND: A dose of 30 mg/kg of azithromycin is recommended for treatment of yaws, a disease targeted for global eradication. Treatment with 20 mg/kg of azithromycin is recommended for the elimination of trachoma as a public health problem. In some settings, these diseases are co-endemic. We aimed to determine the efficacy of 20 mg/kg of azithromycin compared with 30 mg/kg azithromycin for the treatment of active and latent yaws. METHODS: We did a non-inferiority, open-label, randomised controlled trial in children aged 6-15 years who were recruited from schools in Ghana and schools and the community in Papua New Guinea...

Significant overtreatment with antibiotics for suspected early onset sepsis (EOS) constitutes a persisting clinical problem, generating unnecessary risks, harms, and costs for many newborns. We aimed to study feasibility and impact of a sepsis calculator to help guide antibiotic for suspected EOS in a European setting. In this single-center study, the sepsis calculator was implemented as an addition to and in accordance with existing protocols. One thousand eight hundred seventy-seven newborns ≥ 35 weeks of gestational age were prospectively evaluated; an analogous retrospective control group (n = 2076) was used for impact analysis...

The shielding properties of ordinary concrete doped with some micro and nano scaled materials were studied in the current study. Narrow beam geometry was simulated using MCNPX Monte Carlo code and the mass attenuation coefficient of ordinary concrete doped with PbO2 , Fe2 O3 , WO3 and H4 B (Boronium) in both nano and micro scales was calculated for photon and neutron beams. Mono-energetic beams of neutrons (100-3000 keV) and photons (142-1250 keV) were used for calculations. The concrete doped with nano-sized particles showed higher neutron removal cross section (7%) and photon attenuation coefficient (8%) relative to micro-particles...

G protein-coupled receptors (GPCRs) are usually highlighted as being both the largest family of membrane proteins and the most productive source of drug targets. However, most of the GPCRs are understudied and hence cannot be used immediately for innovative therapeutic strategies. Besides, there are still around 100 orphan receptors, with no described endogenous ligand and no clearly defined function. The race to discover new ligands for these elusive receptors seems to be less intense than before. Here, we present an update of the various strategies employed to assign a function to these receptors and to discover new ligands...

BACKGROUND: Management of tardive syndromes (TS) is challenging, with only a few evidence-based therapeutic algorithms reported in the American Academy of Neurology (AAN) guideline in 2013. OBJECTIVE: To update the evidence-based recommendations and provide a practical treatment algorithm for management of TS by addressing 5 questions: 1) Is withdrawal of dopamine receptor blocking agents (DRBAs) an effective TS treatment? 2) Does switching from typical to atypical DRBAs reduce TS symptoms? 3) What is the efficacy of pharmacologic agents in treating TS? 4) Do patients with TS benefit from chemodenervation with botulinum toxin? 5) Do patients with TS benefit from surgical therapy? METHODS: Systematic reviews were conducted by searching PsycINFO, Ovid MEDLINE, PubMed, EMBASE, Web of Science and Cochrane for articles published between 2012 and 2017 to identify new evidence published after the 2013 AAN guidelines...

BACKGROUND: Audit and feedback aims to guide health professionals in improving aspects of their practice that need it most. Evidence suggests that feedback fails to increase accuracy of professional perceptions about clinical performance, which likely reduces audit and feedback effectiveness. This study investigates health professionals' perceptions about their clinical performance and the influence of feedback on their intentions to change practice. METHODS: We conducted an online laboratory experiment guided by Control Theory with 72 intensive care professionals from 21 units...

PURPOSE: To examine whether age-related reference ranges for "normal" prostate-specific antigen (PSA) change (determined in men without prostate cancer) can be used to identify men at high risk of having prostate cancer. METHODS: Subjects were men aged 50-69 years with PSA < 10 ng/mL from the UK-based Prostate Testing for cancer and Treatment (ProtecT) study. Men with prostate cancer were categorized as high or low risk of progression (Low risk: Gleason score ≤ 6 and stage T1-T2a; High risk: Gleason score 7-10 or stage T2C)...

Whole-genome sequencing (WGS) as a first-tier diagnostic test could transform medical genetic assessments, but there are limited data regarding its clinical use. We previously showed that WGS could feasibly be deployed as a single molecular test capable of a higher diagnostic rate than current practices, in a prospectively recruited cohort of 100 children meeting criteria for chromosomal microarray analysis. In this study, we report on the added diagnostic yield with re-annotation and reanalysis of these WGS data ~2 years later...

The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of death in type 2 diabetes are due to ASCVD, including 40% from coronary heart disease (CHD), 15% from heart failure (HF), and 10% from stroke. The association between hyperglycemia and elevated CV risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction did not significantly reduce macrovascular outcomes...

Musculoskeletal modeling allows for analysis of individual muscles in various situations. However, current techniques to realistically simulate muscle response when significant amounts of intentional coactivation is required are inadequate. This would include stiffening the neck or spine through muscle coactivation in preparation for perturbations or impacts. Muscle coactivation has been modeled previously in the neck and spine using optimization techniques that seek to maximize the joint stiffness by maximizing total muscle activation or muscle force...

BACKGROUND: There is a need for evidence of the effectiveness of pre-operative exercise for patients undergoing major cancer surgery; however, recruitment to such trials can be challenging. The PrE-operative Physical Activity (PEPA) Trial will establish the feasibility and acceptability of a pre-operative exercise programme aimed to improve patient outcomes after cytoreductive surgery and pelvic exenteration. The secondary aim is to obtain pilot data on the likely difference in key outcomes (post-operative complications, length of hospital stay, post-operative functional capacity and quality of life) to inform the sample size calculation for the substantive randomised clinical trial...

Despite the U.S. substantially outspending peer high income nations with almost 18% of GDP dedicated to health care, on any number of statistical measurements from life expectancy to birth rates to chronic disease, 1 the U.S. achieves inferior health outcomes. In short, Americans receive a very disappointing return on investment on their health care dollars, causing economic and social strain. 2 Accordingly, the debates rage on: what is the top driver of health care spending? Among the culprits: poor communication and coordination among disparate providers, paperwork required by payors and regulations, well-intentioned physicians overprescribing treatments, drugs and devices, outright fraud and abuse, and medical malpractice litigation...

BACKGROUND: Consensus guidelines for prosthesis selection in infective endocarditis recommend bioprosthetic or mechanical valve replacement based on life expectancy and comorbidity. However, contemporary outcome data are limited to institution series. METHODS: The outcomes of 3,447 patients identified from mandatory discharge databases in California and New York states who had either primary isolated mitral (n=1603) or aortic (n=1,844) valve replacement for active endocarditis between 1998 and 2010, were compared according to whether they received bioprosthetic (n=1,673, 48...
