French National Authority for Health assessment of metabolic surgery for type 2 diabetes remission-A meta-analysis in patients with class I to III obesity.

Objective: Randomized controlled trials (RCTs) have demonstrated the superiority of metabolic surgery (MS) over medical therapy (MT) in patients with obesity and type 2 diabetes, leading, to a joint statement in 2016 proposing MS to patients with class I obesity and uncontrolled glycemia. Yet, these RCTs included few patients with class I obesity (body mass index 30-35 kg/m) and even fewer patients with overweight. Our aim was to provide an updated systematic review (SR) with meta-analysis (MA) of RCTs reporting diabetes remission (DR) after MS in these patients.

Cathepsin S inhibition lowers blood glucose levels in mice.

Aims/hypothesis: Cathepsin S (CatS) belongs to a family of proteases that have been implicated in several disease processes. We previously identified CatS as a protein that is markedly overexpressed in adipose tissue of obese individuals and downregulated after weight loss and amelioration of glycaemic status induced by gastric bypass surgery. This prompted us to test whether the protease contributes to the pathogenesis of type 2 diabetes using mouse models with CatS inactivation.

Relevance of increased serum cystatin C to vascular alterations in obese children.

Objective: Epidemiological studies report a positive relationship between serum cystatin C and cardiovascular outcomes in adults. Here, we tested the relevance of cystatin C as a biomarker for early vascular alterations in severely obese children.

Methods: Two hundred nineteen obese (140 girls; age = 11.

Cathepsins and cystatin C in atherosclerosis and obesity.

Given the increasing prevalence of human obesity worldwide, there is an urgent need for a better understanding of the molecular mechanisms linking obesity to metabolic and cardiovascular diseases. Our knowledge is nevertheless limited regarding molecules linking adipose tissue to downstream complications. The importance of cathepsins was brought to light in this context.

Oral administration of dehydroepiandrosterone to healthy men: alteration of the urinary androgen profile and consequences for the detection of abuse in sport by gas chromatography-mass spectrometry.

Dehydroepiandrosterone (DHEA) replacement therapy as compensation for high age-related decline of DHEA and DHEA sulfate production is a matter of intense investigation, since many beneficial effects have been proven, or are suggested and expected. Therefore, DHEA abuse by athletes has been considered by the International Olympic Committee, which banned the substance recently. As DHEA for oral supplementation is easily available, we decided to investigate the effect on the urinary androgen profile of administration along this route of a single substitution dose of 50 mg.
