Brief summary: Steroid analysis using LC-MS/MS in association with clinical parameters may be used to develop a diagnostic score that could successfully differentiate premature pubarche (PP) from non-classic congenital adrenal hyperplasia (NCCAH), thereby obviating the need for ACTH stimulation testing.Late onset, non-classic congenital adrenal hyperplasia (NCCAH) due to 21-hydroxylase deficiency (21-OHD) should be ruled out in children with premature pu...

Brief summary: The authors used data from the Global Burden of Disease 2019 to examine the incidence, disability adjusted life years and mortality of early onset type 2 diabetes T2D) in those 15–39 years of age. This showed that early onset T2D is a growing global health problem in adolescents and young adults, particularly in low-middle- and middle-income countries.Early onset of type 2 diabetes (T2D) is associated with longer lifetime exposure hyp...

To read the full abstract: JCI Insight. 2018 Oct 18;3(20). pii: 99631.This paper describes a new form of goitrous congenital hypothyroidism associated with mutations in the solute carrier family 26 member 7 gene (SLC26A7) in 6 unrelated families. In patients, a partial iodide organification defect (PIOD) with normal iodide uptake was observed, hence these mutations cause a new f...

To read the full abstract: Science 2018;360:1087-1092During the Cardiovascular Risk Survey in western China, a Kazakh family with inherited low levels of LDL-C was identified. The Kazakhs are mainly descendent from the Turkic and medieval Mongol peoples, they live in isolated regions and usually marry within their own ethnic group. They exhibit often unique differences in single nucleotide vari...

Brief summary: This randomized, multicenter, controlled, phase II study compared the effects of high-dose (HD) once-weekly PEGylated-recombinant human growth hormone (PEG-rhGH) to low-dose (LD) and to an untreated control group of children with idiopathic short stature (ISS) over a period of 52 weeks. PEG-rhGH was effective in increasing height gain in a dose dependent manner with both doses being well tolerated during the observation period.PEG-rhGH is ...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...

Nat Commun. 2020 Aug 13;11(1):4063. doi: 10.1038/s41467-020-17890-2. PMID: 32792525.These researchers proposed the heterogeneity of hypothalamic neural progenitor cells. Other than traditional hypothalamic radial glial (hRG) cells, which are predominantly located in the ventricular zone, there are additional basal progenitors in the mantle zone, which are named as hypothalamic mantle zo...

PMID: 33164986.This manuscript describes a novel disorder due to homozygous mutations in the YIPF5 gene which cause a complex syndrome of neonatal/early onset diabetes mellitus, epilepsy and microcephaly. The underlying mechanism of the diabetes involves the accumulation of proinsulin (unable to be transported to the Golgi...
