BACKGROUND: Capsular contracture has been the most common complication of cosmetic breast augmentation. The effect of incision pattern on capsular contracture is still unclear. This meta-analysis demonstrates current evidence with regard to the comparison of capsular contracture rate between periareolar and other two (transaxillary and inframammary) incisions. METHODS: PubMed, EMBASE, and Cochrane databases were searched up to January 2017. The results of selected studies were meta-analyzed to obtain a pooled odds ratio of the effect of periareolar versus other two incision patterns (transaxillary or inframammary incision) of breast augmentation on capsular contracture rates...

BACKGROUND: Despite widely recommended usage of cyclosporine A (CsA) in chronic spontaneous urticaria (CSU), there is no meta-analysis concerning its efficacy and safety. OBJECTIVE: To meta-analyze and review the efficacy and safety of CsA in CSU. METHODS: Efficacy was assessed by the relative change in urticaria activity score at 4 weeks and response rates at 4, 8, and 12 weeks. Safety was assessed by analyzing the number of patients with 1 or more adverse event...

Rheumatoid arthritis is an autoimmune disease in which probiotics appears to have an immune modulating action along with decreased inflammatory process. Therefore, we aim to investigate the efficacy of probiotics as an adjuvant therapy for rheumatoid arthritis. A comprehensive literature search was performed using nine databases including PubMed and Web of Science. Interesting data was extracted and meta-analyzed. We assessed the risk of bias using Cochrane Collaboration's tool. The protocol was registered in PROSPERO (CRD 42016036769)...

Treatment intensification to maximize disease control and reduced-intensity approaches to minimize the risk of late sequelae have been evaluated in newly diagnosed Hodgkin lymphoma. The influence of these interventions on the risk of secondary malignant neoplasms, progression-free survival and overall survival is reported in the present meta-analysis based on individual patient data from 9498 patients treated within 16 randomized controlled trials for newly diagnosed Hodgkin lymphoma between 1984 and 2007. Secondary malignant neoplasms were meta-analyzed using Peto's method as time-to-event outcomes...

Background: The Lives Saved Tool (LiST) is a software model that estimates the health impact of scaling up interventions on maternal and child health. One of the outputs of the model is an estimation of births by fetal size [appropriate-for-gestational-age (AGA) or small-for-gestational-age (SGA)] and by length of gestation (term or preterm), both of which influence birth weight. LiST uses prevalence estimates of births in these categories rather than of birth weight categories, because the causes and health consequences differ between SGA and preterm birth...

Sleep disturbances and dementia are two common and significant health problems in older adults. Investigations suggest that sleep disturbances might increase the risk of dementia. The aim of the present study was to systematically review and meta-analyze the predictive roles of overall sleep disturbances, their subtypes (e.g., insomnia, sleep disordered breathing [SDB]), and other sleep problems (e.g., excessive daytime sleepiness, sleep-related movement disorder, circadian rhythm sleep disorder, and nonspecific sleep problems) in incident all-cause dementia and Alzheimer's disease (AD) and vascular dementia subtypes...

Motivation: Meta-analysis is essential to combine the results of genome-wide association studies (GWASs). Recent large-scale meta-analyses have combined studies of different ethnicities, environments and even studies of different related phenotypes. These differences between studies can manifest as effect size heterogeneity. We previously developed a modified random effects model (RE2) that can achieve higher power to detect heterogeneous effects than the commonly used fixed effects model (FE)...

Motor symptoms in Gilles de la Tourette syndrome (GTS) have been related to changes in frontostriatal brain networks. These changes may also give rise to alterations in cognitive flexibility. However, conclusive evidence for altered cognitive flexibility in patients with GTS is still lacking. Here, we meta-analyzed data from 20 neuropsychological studies that investigated cognitive flexibility in GTS using the Wisconsin Card Sorting Test (WCST). Results revealed medium-sized GTS-related performance deficits, which were significantly modulated by age: Whilst being substantial in children and adolescents with GTS, WCST deficits seem to dissolve in adult patients with GTS...

Heritability is the proportion of phenotypic variance in a population that is attributable to individual genotypes. Heritability is considered an important measure in both evolutionary biology and in medicine, and is routinely estimated and reported in genetic epidemiology studies. In population-based genome-wide association studies (GWAS), mixed models are used to estimate variance components, from which a heritability estimate is obtained. The estimated heritability is the proportion of the model's total variance that is due to the genetic relatedness matrix (kinship measured from genotypes)...

BACKGROUND: It is currently unknown whether individuals with SBP/DBP values in the ranges 120-139/80-89 mmHg, usually defined as with prehypertension or high-normal and normal blood pressure (BP), benefit from BP-lowering treatment and whether benefits in these individuals depend on the level of their cardiovascular risk. OBJECTIVES: Meta-analyzing all available data from randomized controlled trials (RCTs) about the effects on cardiovascular outcomes of BP-lowering treatment in individuals with normal or high-normal BP values in absence of baseline antihypertensive drugs and free from a recent myocardial infarction, left ventricular dysfunction and heart failure...

Myopia (short-sightedness) and hyperopia (long-sightedness) occur when the eye grows too long or short, respectively, for its refractive power. There are currently approximately 1.45 billion myopes worldwide and prevalence is rising dramatically. Although high myopia significantly increases the risk of developing a range of sight-threatening disorders, the molecular mechanisms underlying ocular growth regulation and its relationship to these secondary complications remain poorly understood. Thus, this study meta-analyzed transcriptome datasets collected in the commonly used chick model of optically-induced refractive error...
