Samson Henry Dogo, Allan Clark, Elena Kulinskaya
Temporal changes in magnitude of effect sizes reported in many areas of research are a threat to the credibility of the results and conclusions of meta-analysis. Numerous sequential methods for meta-analysis have been proposed to detect changes and monitor trends in effect sizes so that meta-analysis can be updated when necessary and interpreted based on the time it was conducted. The difficulties of sequential meta-analysis under the random-effects model are caused by dependencies in increments introduced by the estimation of the heterogeneity parameter τ(2) ...

INTRODUCTION: On the basis of six meta-analyses, the guidelines of the European Hernia Society (EHS) recommend laparo-endoscopic recurrent repair following previous open inguinal hernia operation and, likewise, open repair following previous laparo-endoscopic operation. So far no data are available on implementation of the guidelines or for comparison of outcomes. Besides, there are no studies for comparison of outcomes for compliance versus non-compliance with the guidelines. PATIENTS AND METHODS: In total, 4812 patients with elective unilateral recurrent inguinal hernia repair in men were enrolled between September 1, 2009, and September 17, 2014, in the Herniamed Registry...

T Verse, B A Stuck
Uvulopalatopharyngoplasty (UPPP) was first described in 1964 with regard to surgical treatment of snoring and in 1981 with regard to treatment of obstructive sleep apnea (OSA). The initial surgical techniques for OSA were very invasive, frequently leading to significant morbidity and complications. Wolfgang Pirsig et al. were the first in Germany to recognize that a radical surgical technique increased only the complications, not the efficacy of UPPP. The less invasive surgical technique developed based on these findings is still established in Germany...

BACKGROUND: When comparing clinical studies nationally and internationally, there is great heterogeneity in the applied audiometric outcome parameters. Beside different frequencies included in pure-tone audiometry and the resulting averages, the word recognition scores are measured at varying sound pressure levels, i.e., either with a fixed sound pressure level or with a fixed sensation level. However, a comparison of studies, e. g., in meta-analysis, requires comparable outcome parameters...

OBJECTIVES: Calcium pyrophosphate crystal deposition disease (CPPD) is common, yet prevalence and overall clinical impact remain unclear. Sensitivity and specificity of CPPD reference standards (conventional crystal analysis (CCA) and radiography (CR)) were meta-analysed by EULAR (published 2011). Since then, new diagnostic modalities are emerging. Hence, we updated 2009-2016 literature findings by systematic review and evidence grading, and assessed unmet needs. METHODS: We performed systematic search of full papers (PubMed, Scopus/EMBASE, Cochrane 2009-2016 databases)...

It may not always be possible to blind participants of a randomized controlled trial for treatment allocation. As a result, estimators of the actual treatment effect may be biased. In this paper, we will extend a novel method, originally introduced in genetic research, for instrumental variable meta-analysis, adjusting for bias due to unblinding of trial participants. Using simulation studies, this novel method, "Egger Correction for non-Adherence", is introduced and compared to the performance of the "intention-to-treat," "as-treated," and conventional "instrumental variable" estimators...

Vitamin D deficiency is associated with a decreased insulin release, insulin resistance and type 2 diabetes in experimental and epidemiological studies. Animal studies show that 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3) stimulates the pancreatic β-cell to secrete insulin. The relationship between vitamin D deficiency and insulin resistance could develop through inflammation, as vitamin D deficiency is associated with increased inflammatory markers. In addition, genetic polymorphisms of vitamin D -related genes may predispose to impaired glycemic control and type 2 diabetes...

AIM: To investigate the ability of arterial spin labelling (ASL) perfusion parameters to distinguish high-grade from low-grade gliomas. MATERIALS AND METHODS: The PubMed and EMBASE databases were systematically searched for relevant articles published up to September 2015. Studies that evaluated both high- and low-grade gliomas using ASL were included. The random effect model was used to calculate the standardised mean difference (SMD) of maximum mean absolute tumour blood flow values (aTBFmax, aTBFmean) and maximum mean relative tumour blood flow (rTBFmax, rTBFmean) between high- and low-grade gliomas...

BACKGROUND AND OBJECTIVE: Recent GWAS and meta-analyses have revealed about 200 susceptibility genes/loci for inflammatory bowel diseases (IBD). However, only a small number of studies were performed in early-onset IBD. The aim of this study was to assess the association between NOD2, IL23R, ATG16L1, IRGM, IL10, NKX2-3 and ORMDL3 variants and early-onset IBD. MATERIALS AND METHODS: A total of 76 affected individuals (30 with Crohn's disease [CD] and 46 with ulcerative colitis [UC]) at the age of ≤17 years and 158 matched controls recruited in Lithuania were genotyped for the known genetic susceptibility variants in NOD2 (Arg702Trp (rs2066844), Gly908Arg (rs2066845) and Leu1007insC (rs2066847)), IL23R (rs11209026), ATG16L1 (rs2241880), IRGM (rs4958847), IL10 (rs3024505), NKX2-3 (rs11190140) and ORMDL3 (rs2872507) genes...

Diagnosis of bovine respiratory disease (BRD) in beef cattle placed in feedlots is typically based on clinical illness (CI) detected by pen-checkers. Unfortunately, the accuracy of this diagnostic approach (namely, sensitivity [Se] and specificity [Sp]) remains poorly understood, in part due to the absence of a reference test for ante-mortem diagnosis of BRD. Our objective was to pool available estimates of CI's diagnostic accuracy for BRD diagnosis in feedlot beef cattle while adjusting for the inaccuracy in the reference test...

Atomoxetine, a non-stimulant, is FDA approved drug used in the management of adult ADHD. Since the presentation of adult ADHD is different from the childhood onset condition, there is an urgent need to study the efficacy of atomoxetine on the different symptom domains of adult ADHD. To study the efficacy of atomoxetine in treating adult ADHD compared to placebo, we performed a Medline search for English language publications of Randomized Controlled Trials (RCTs) comparing atomoxetine to placebo for adult ADHD using the keywords "adult ADHD", "atomoxetine" and "placebo"...
