Muscular strength is a modifiable protective factor for mental health across aging populations. Evidence of sex-related differences in its associations with mental health is limited. Therefore, the purpose of this study was to examine sex-related differences in cross-sectional and prospective associations between grip strength and depressive symptoms and status. Participants were community dwelling adults (N = 4505; 56.5% female), aged ≥50 years. As a measure of muscular strength, grip strength (kg) of the dominant hand was assessed using a hand-held dynamometer at baseline...

OBJECTIVE: Interaction between advanced glycation end-products (AGEs) and receptor for AGEs (RAGE) in cells could affect both extracellular and intracellular structure and function, which plays a pivotal role in diabetic microvascular complications. The results from previous epidemiological studies on the association between RAGE gene -374T/A polymorphism and diabetic retinopathy (DR) risk were inconsistent. Thus, we conducted this meta-analysis to summarize the possible association between RAGE -374T/A polymorphism and DR risk...

BACKGROUND: Spigelian hernia (SH) is a rare entity, but its surgical treatment is essential because of its high complication risk. Laparoscopic approaches have become the option in elective surgery because it has less morbidity and requires a shorter stay. Several laparoscopic techniques have been employed, but there is no gold standard technique for this kind of hernia. We report, in this study, our experience with intraperitoneal onlay mesh (IPOM) repair. MATERIALS AND METHODS: Fifteen patients underwent elective surgery for SH between 2008 and 2015 in a Short-Stay Surgical Unit...

Purpose: We sought to determine whether big data from social media might reveal seasonal trends of conjunctivitis, most forms of which are nonreportable. Methods: Social media posts (from Twitter, and from online forums and blogs) were classified by age and by conjunctivitis type (allergic or infectious) using Boolean and machine learning methods. Based on spline smoothing, we estimated the circular mean occurrence time (a measure of central tendency for occurrence) and the circular variance (a measure of uniformity of occurrence throughout the year, providing an index of seasonality)...

It is estimated that more than 200 million individuals are affected by lower extremity artery disease (LEAD) worldwide. This prevalence has increased between 2000 and 2010 by 25%, especially in low/middle income countries. In France, about one million people are affected by this condition. Almost two-thirds of patients with LEAD are asymptomatic. This explains the interest of the measurement of the ankle-brachial index (ABI), an objective and harmless diagnostic tool. An ABI≤0.90 is considered as diagnostic for LEAD...
