To read the full abstract: J Clin Endocrinol Metab. 2019;104:5765–5779.It is not clear whether retesting is needed for a healthy cotwin of a twin pair discordant for congenital hypothyroidism (CH) at the first neonatal screening. Medda et al. retrospectively analyzed a cohort of 47 twin pairs discordant for CH at the first neonatal screening. On follow-up, 7 (15%) of cotwins who were initially negatively screened then tested positi...

Brief Summary:This study in mice and humans shows how paternal overweight at conception affects the metabolism of their offspring. Sperm-borne mt-sncRNAs (mitochondrial encoded or derived small non-coding RNAs) are altered by a 2-week high fat diet (HFD) challenge in mice, likely through specific upregulation of mt-tsRNAs (mitochondrial transfer RNAs) caused by mitochondrial dysfunction. In humans, mt-tsRNAs in spermatozoa correlate with body mass index. Genetically engineered...
