Brief summary: This retrospective case-control observational study assessed body composition of children with non-classic congenital adrenal hyperplasia (NCCAH) using bioelectrical impedance analysis (BIA). It showed that children with NCCAH have an imbalance between muscle and fat tissues compared with control subjects, which may place them at increased risk for early-onset cardiometabolic morbidity.Non-classic congenital adrenal hyperplasia (NCCAH) is ...

Alcantara J Ramirez , NR Grant , S Sethuram , A Nagy , C Becker , I Sahai , T Stanley , A Halper , FS Eichler

Brief Summary: This retrospective chart review included 116 patients aged 0 to 17 y (M:F 94%:6%) with X-linked adrenoleukodystrophy (ALD) managed in one expert medical center from 2006 to 2022. It assessed the impact of newborn screening (which began in the U.S. in 2013 based on measurement of a lysophosphatidylcholine derivative of a very long chain fatty acid (VLCFA) C26:0-LPC, followed if abnormal by ABCD1 gene sequencing), on the age and presentation of adrenal in...

Brief Summary: This basic science study examined how 3,5,3’-triiodothyroacetic acid (TRIAC) - a thyroid hormone (TH) receptor agonist used in patients with resistance to TH, and in patients with Allan-Herndon-Dudley syndrome (AHDS), caused by mutations in monocarboxylate transporter 8 (MCT8) - is transported into cells independent of MCT8. Through a genome-wide RNAi screening in HepG2 cells, two key transporters, SLC22A9 (OAT7) and SLC29A2 (ENT2), were identified that fac...

To read the full abstract: JAMA. 2018;319:38-48Earlier observational studies showed that dietary exposure to complex proteins in newborns and early infants is associated with beta cell autoimmunity and increase the risk for T1DM. Several studies avoiding certain proteins, such as gluten and casein, have been conducted without reducing the risk for T1D in genetically susceptible children. Theref...
