Brief Summary: This longitudinal study explored the impact of metabolic surgery on the growth hormone (GH)/IGF-1 axis and its subsequent effects on adipose tissue function. The results suggest that bariatric surgery enhances GH-IGF-1 levels, which are linked to improved adipose tissue function and a reduction in inflammation markers.This study explored how metabolic surgery influences the GH system, and how these changes are related to improvements in ad...

To read the full abstract: Proc Natl Acad Sci USA. 2018; 115(52): E12265–E12274.The adrenal cortex plays a central role in regulating body homeostasis through the production of glucocorticoids and mineralocorticoids that control many important physiologic functions, such as metabolism, inflammation and arterial blood pressure. The production of these hormones, known as steroid...

Brief summary: In this in vivo study, Xia et al. demonstrate that AAV-mediated gene therapy recovers testosterone levels, restarts sexual development, restores spermatogenesis, and produces fertile offspring in a mouse model of Leydig cell failure (LCF).A null mutation in the gene encoding luteinizing hormone/choriogonadotrophin receptor (Lhcgr) causes a hereditary LCF in mice which is characterized by a reduction in testosterone levels...

Brief summary: In this double-blind, randomized clinical trial conducted in 6 US centres, 88 children and adolescents (aged 7–17 years) with newly diagnosed type 1 diabetes (T1D) were randomized to either once-daily oral verapamil or placebo, within 1 month from diagnosis. Treatment with verapamil led to better stimulated C-peptide secretion at 52 weeks post-diagnosis, with levels 30% higher compared to placebo.Verapamil is a calcium channel blocker...

Brief summary: This international multicentre study collected data from 104 290 children and adolescents (6 months-18 years-old), to compare prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes (T1D) before and during the COVID-19 pandemic. Prevalence of DKA at T1D diagnosis increased from 27.3% pre-pandemic to 39.4% during the pandemic, and the increased trends were associated with the pandemic containment measures.DKA is a life-thr...
