J Steroid Biochem Mol Biol. 2020; 200:105684.https://pubmed.ncbi.nlm.nih.gov/32360359/In this mouse cell model, the authors show that metformin appears to directly inhibit signaling of MC2R (the ACTH receptor) and also MC3R.Metformin is used to treat type 2 diabetes and obesity, and may reduce the androgen excess in women with polycystic ovary syndrome (PCOS) or conge...

Metformin use was associated with lower birth weights (overall mean difference −107.7 g), lower ponderal indices, and lower odds of macros...

Brief summary: This review covers the recent advances in the understanding of fetal adrenal development and the interplay with the feto-placental unit. A short overview of related adrenal disorders is presented. The effect of other hormone systems is also discussed and the reliability of using rodent models to study adrenal pathophysiology.Structural development of the fetal adrenal and its transition to the adult organ: There are differ...

To read the full abstract: Diabetes Care 2018;41:1089-1096These findings show that a 1-SD increase in childhood BMI was associated with a 47–83% increased relative risk of T2DM and a 28% increased relative risk of CAD in adult life, yet childhood BMI was not associated with adult chronic kidney disease. This is the first study to examine the causal relationship between childhood BMI and cardio-...

J Clin Endocrinol Metab. 2022; 107(2): e487-e499. PMID: 34599587https://pubmed.ncbi.nlm.nih.gov/34599587/Brief Summary: This study describes the growth of adequately treated children with classical Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency during adrenarche and beyond. Patients with and without significant bone age advancement, and thus differing height prediction...

Psychoneuroendocrinology. 2022; 137: 105604. PMID: 34971856https://pubmed.ncbi.nlm.nih.gov/34971856/Brief Summary: This study evaluated the associations between the amygdala total and sub-region volumes in relation to sex hormones – estradiol and free testosterone – as a function of age and genetic differences in androgen receptor sensitivity in 297 adolescents. It provides new kno...

Proc Natl Acad Sci U S A. 2021 Oct 12;118(41):e2107208118. https://pubmed.ncbi.nlm.nih.gov/34611019/Brief Summary: This in vitro study explored the reactivity to preproinsulin of CD8 T cells obtained from pancreatic islets of individuals with and without type 1 diabetes (T1D). The main finding was that CD8 T cells from T1D donors were highly reactive to peptides throughout the entire prepro...

Nature. 2021;596(7872):393-7. doi: 10.1038/s41586-021-03779-7.PubMed ID: 34349265Brief summary: This study analysed genome-wide association array (GWAS) data on ~200 000 women of European ancestry to identify 290 separate genetic signals associated with normal variation in age at natural menopause (ANM). Experimental alterations of key identified genes in mouse models confirmed their impac...

To read the full abstract: Radiology 2018:171170Current American Thyroid Association (ATA) guidelines recommend the application of adult ultrasound criteria to classify thyroid nodules in children and adolescents1. However, few studies have evaluated the sonographic and demographic features that could predict malignancy in a large cohort of young patients with thyroid nodules.</p...

Brief summary: This prospective observational cohort study determined leukocyte telomere length (LTL) in 76 patients with genetically confirmed CAH (83% classic CAH). LTL was shorter in patients with classic vs nonclassic CAH, in overtreated than in optimally treated patients, and patients receiving prednisolone compared with hydrocortisone.Telomeres are tandem repeats of a noncoding hexameric nucleotide sequence (5′-TTAGGG-3′) located at the...
