Brief Summary: This study compared 2 groups of adults defined by their leptin concentrations relative to fat mass. Adults with ‘relatively high leptin’ (RHL, n=646) or ‘relatively low leptin’ (RLL, n=644) concentrations were compared in insulin concentration, insulin secretion, and insulin sensitivity, at both the whole-body level and within adipose tissue. Individuals with RHL showed a distinct metabolic phenotype, characterized by insulin resistance in bo...

J Clin Endocrinol Metab. 2020 Dec 1;105(12):dgaa633. doi: 10.1210/clinem/dgaa633. PMID: 32898218.In this study, low risk pregnant women had an ‘early’ OGTT at 18-20 weeks of gestation and these results were correlated with the standard OGTT at 24-28 weeks. Pregnant women with Gestational diabetes mellitus (GDM) who had early OGTT still had a higher risk of delivering macrosomic in...

Matrix Biol. 2020 Aug;90:40–60 Abstract: https://pubmed.ncbi.nlm.nih.gov/32173581/In brief: Mutations in 3-hydroxylation complex genes CRTAP and P3H1 cause osteogenesis imperfecta type VII and VIII, respectively. However, the pathogenic mechanism by which these mutations cause disease remains unclear. This study points to a defective chaperone role of the 3-h...
