To read the full abstract: Proc Natl Acad Sci U S A. 2019; 116(44): 22294-22299. PMID: 31611378.Androgen biosynthesis in the human fetus proceeds through the adrenal sex steroid precursor dehydroepiandrosterone (DHEA), which is converted to testosterone in the gonads, followed by further activation to 5α-dihydrotestosterone (DHT) in genital skin, thereby facilitating male external genit...

Cochrane Database Syst Rev. 2022 Mar 18;3(3):CD011027. doi: 10.1002/14651858.CD011027.pub3. PMID: 35302645.Brief Summary: This systematic review assessed the evidence for oral dextrose gel to treat hypoglycemia in newborns. Oral dextrose gel compared with placebo gel probably improved the correction of hypoglycaemic events and may result in a slight reduction in the risk of ma...
