Validation of the greater trochanter method with radiographic measurements of frontal plane hip joint centers and knee mechanical axis angles and two other hip joint center methods.

Several motion capture methods exist for predicting hip joint centers (HJC). These methods include regression models, functional joints, and projections from greater trochanters. While regression and functional methods have been compared to imaging techniques, the TROCH method has not been previously validated.

Improving Outcomes in Elective Colorectal Surgery: A Single-institution Retrospective Review.

Our hospital, a Tennessee Surgical Quality Collaborative (TSQC) member, adopted a statewide colorectal care bundle intended to reduce surgical site infections (SSI) in elective colorectal cases. The bundle includes proper antibiotics/dosing, normoglycemia, normothermia, supplemental oxygen six hours postoperatively, and early enteral nutrition. A single-institution retrospective study of our National Surgical Quality Improvement Program (NSQIP) database for the rates of SSI before and after the colorectal bundle.

The total synthesis of K-252c (staurosporinone) a sequential C-H functionalisation strategy.

A synthesis of the bioactive indolocarbazole alkaloid K-252c (staurosporinone) a sequential C-H functionalisation strategy is reported. The route exploits direct functionalisation reactions around a simple arene core and comprises of two highly-selective copper-catalysed C-H arylations, a copper-catalysed C-H amination and a palladium-catalysed C-H carbonylation, which build up the structural complexity of the natural product framework.

A Network Meta-analysis Comparing Exenatide Once Weekly with Other GLP-1 Receptor Agonists for the Treatment of Type 2 Diabetes Mellitus.

Introduction: Exenatide is a glucagon-like peptide-1 receptor agonist (GLP-1 RA), approved for treatment of type 2 diabetes mellitus (T2DM). There is limited direct evidence comparing the efficacy and tolerability of exenatide 2 mg once weekly (QW) to other GLP-1 RAs. A network meta-analysis (NMA) was conducted to estimate the relative efficacy and tolerability of exenatide QW versus other GLP-1 RAs for the treatment of adults with T2DM inadequately controlled on metformin monotherapy.

Biomarkers of Dietary Intake Are Correlated with Corresponding Measures from Repeated Dietary Recalls and Food-Frequency Questionnaires in the Adventist Health Study-2.

Background: Accurate assessment of diet in study populations is still a challenge. Some statistical strategies that use biomarkers of dietary intake attempt to compensate for the biasing effects of reporting errors.

Objective: The objective was to correlate biomarkers of dietary intake with 2 direct measures of dietary intake.

The genomic basis of parasitism in the Strongyloides clade of nematodes.

Soil-transmitted nematodes, including the Strongyloides genus, cause one of the most prevalent neglected tropical diseases. Here we compare the genomes of four Strongyloides species, including the human pathogen Strongyloides stercoralis, and their close relatives that are facultatively parasitic (Parastrongyloides trichosuri) and free-living (Rhabditophanes sp. KR3021).

Network meta-analysis of treatments for type 2 diabetes mellitus following failure with metformin plus sulfonylurea.

Unlabelled: Aims The efficacy and safety of sodium-glucose linked transporters (SGLT2s) plus metformin and a sulfonylurea (MET + SU) for the treatment of type 2 diabetes mellitus (T2DM) in patients who fail to achieve glycemic control with MET + SU, relative to other triple therapies licensed in the EU, were estimated. Methods A systematic literature review and network meta-analysis (NMA) of randomized controlled trials (RCTs) involving anti-diabetes treatments added to MET + SU were conducted.

Results: Of 2236 abstracts identified through a systematic literature review, 30 RCTs published between 2003 and 2013 were included.

Validity of Submaximal Step Tests to Estimate Maximal Oxygen Uptake in Healthy Adults.

Background: Aerobic capacity (VO2max) is a strong predictor of health and fitness and is considered a key physiological measure in the healthy adult population. Submaximal step tests provide a safe, simple and ecologically valid means of assessing VO2max in both the general population and a rehabilitation setting. However, no studies have attempted to synthesize the existing knowledge regarding the validity of the multiple step-test protocols available to estimate VO2max in the healthy adult population.

The global burden of major infectious complications following prostate biopsy.

We present a systematic review providing estimates of the overall and regional burden of infectious complications following prostate biopsy. A directly standardized prevalence estimate was used because it reflects the burden of disease more explicitly. Complications included sepsis, hospitalization, bacteraemia, bacteriuria, and acute urinary retention after biopsy.

The cost-effectiveness of daclatasvir-based regimens for the treatment of hepatitis C virus genotypes 1 and 4 in the UK.

Objective: This study aimed to determine the cost-effectiveness of daclatasvir in combination with other medicinal products for the treatment of patients with hepatitis C virus genotypes 1 and 4 and advanced liver disease in the UK.

Methods: A published and validated Markov model designed to simulate the natural history of chronic hepatitis C was used to compare daclatasvir with relevant treatment options for patients with hepatitis C virus genotypes 1 and 4 and a METAVIR score of F3-F4. Patients were defined according to their treatment status; that is, naive, experienced or interferon ineligible/intolerant.

The Evolution of the Secreted Regulatory Protein Progranulin.

Progranulin is a secreted growth factor that is active in tumorigenesis, wound repair, and inflammation. Haploinsufficiency of the human progranulin gene, GRN, causes frontotemporal dementia. Progranulins are composed of chains of cysteine-rich granulin modules.

Validation of the UKPDS 82 risk equations within the Cardiff Diabetes Model.

Background: For end-users of diabetes models that include UKPDS 82 risk equations, an important question is how well these new equations perform. Consequently, the principal objective of this study was to validate the UKPDS 82 risk equations, embedded within an established type 2 diabetes mellitus (T2DM) model, the Cardiff Diabetes Model, to contemporary T2DM outcomes studies.

Methods: A total of 100 validation endpoints were simulated across treatment arms of twelve pivotal T2DM outcomes studies, simulation cohorts representing each validation study's cohort profile were generated and intensive and conventional treatment arms were defined in the Cardiff Diabetes Model.

Novel Ranking System for Identifying Efficacious Anti-Influenza Virus PB2 Inhibitors.

Through antigenic drift and shifts, influenza virus infections continue to be an annual cause of morbidity in healthy populations and of death among elderly and at-risk patients. The emergence of highly pathogenic avian influenza viruses such as H5N1 and H7N9 and the rapid spread of the swine-origin H1N1 influenza virus in 2009 demonstrate the continued need for effective therapeutic agents for influenza. While several neuraminidase inhibitors have been developed for the treatment of influenza virus infections, these have shown a limited window for treatment initiation, and resistant variants have been noted in the population.

Effect of Mucosal Cytokine Administration on Selective Expansion of Vaginal Dendritic Cells to Support Nanoparticle Transport.

Problem: The capacity of antigen-carrying vaccine nanoparticles (NPs) administered vaginally to stimulate local immune responses may be limited by the relatively low numbers of antigen-presenting cells (APCs) in the genital mucosa. Because inflammation is associated with increased susceptibility to sexually transmitted infections, we sought to increase APC numbers without causing inflammation.

Method Of Study: In this study, we evaluated intravaginal delivery of chemokines, growth factors, or synthetic adjuvants to expand APCs in reproductive tissues.

Health, fairness and New Zealand's contribution to global post-2020 climate change action.

Health and wellbeing have been largely ignored in discussions around climate change targets and action to date. The current public consultation around New Zealand's post-2020 climate target is an opportunity for health professionals to highlight the health implications of climate change. Without urgent global efforts to bring down global GHG (greenhouse gas) emissions, the world is heading towards high levels of global warming, which will have devastating impacts on human health and wellbeing.

A review of the burden of hepatitis C virus infection in China, Japan, South Korea and Taiwan.

Hepatitis C virus (HCV) infection is associated with substantial clinical and economic burden and is an important public health issue in Asia. The objective of this review was to characterize HCV epidemiology and related complications in China, Japan, South Korea and Taiwan. A search of electronic databases and conference abstracts identified 71 potentially relevant articles.

Is antenatal screening for hepatitis C virus cost-effective? A decade's experience at a London centre.

Background & Aims: This study aims to assess the cost-effectiveness of a routine universal antenatal hepatitis C virus (HCV) screening programme at a London centre.

Methods: Ten years' retrospective antenatal screening and outcome data informed a cost-effectiveness analysis using the previously validated MONARCH model. The cost and quality of life outcomes associated with the screening and treatment of newly identified hepatitis C cases were used to generate cost-effectiveness estimates for the screening programme.

Effects of Two Football Stud Types on Knee and Ankle Kinetics of Single-Leg Land-Cut and 180° Cut Movements on Infilled Synthetic Turf.

Higher ACL injury rates have been recorded in cleats with higher torsional resistance in American football, which warrants better understanding of shoe/stud-dependent joint kinetics. The purpose of this study was to determine differences in knee and ankle kinetics during single-leg land cuts and 180° cuts on synthetic infilled turf while wearing 3 types of shoes. Fourteen recreational football players performed single-leg land cuts and 180° cuts in nonstudded running shoes (RS) and in football shoes with natural (NTS) and synthetic turf studs (STS).

Assessing the Long-Term Impact of Treating Hepatitis C Virus (HCV)-Infected People Who Inject Drugs in the UK and the Relationship between Treatment Uptake and Efficacy on Future Infections.

Objective: The prevalence of the hepatitis C virus (HCV) remains high amongst people who inject drugs (PWID) and accounts for the majority of newly acquired infections. This study aims to quantify the value of treatment amongst PWID with more efficacious treatments and at increased uptake rates, with respect to the avoidance of future infections and subsequent long-term complications of HCV.

Methods: A dynamic HCV transmission and disease progression model was developed, incorporating acute and chronic infection and their long-term complications (decompensated cirrhosis, cancer, liver transplant and mortality), with the potential for HCV transmission to other PWID prior to successful treatment.

Comparison of Three Cognitive Screening Tools in Older Urban and Regional Aboriginal Australians.

Background: Validated cognitive screening tools for use in urban and regional Aboriginal populations in Australia are lacking.

Methods: In a cross-sectional community-based study, 235 participants were assessed on the Mini-Mental State Examination (MMSE), the Rowland Universal Dementia Assessment Scale (RUDAS) and an urban modification of the Kimberley Indigenous Cognitive Assessment (mKICA). Performance on these cognitive screening tools was compared to dementia diagnosis by clinical consensus.
