To read the full abstract: J Clin Endocrinol Metab 2017; 102:1702-1711Short stature is a common feature of children with Prader-Willi syndrome (PWS) as well as hypotonia, hyperphagia, obesity, hypogonadism, behavioral disturbances and hypothalamic dysfunction. Alterations in the GH/IGF1 axis are common in patients with PWS, GH deficiency occurring in approximately 74% and IGF-1...

Diabetes Care. 2020; 43:82–89. doi: 10.2337/dc19-0747.It is often difficult to identify maturity-onset diabetes of the young (MODY) in pediatric patients close to diabetes onset. Hence, misdiagnosis and unnecessary insulin treatment are still common.This study reports the discriminatory clinical features at diabetes onset in Swedish pediatric patients (age 1–18 y...

To read the full abstract: Best Pract Res Clin Endocrinol Metab. 2020:101418. PMID: 32414619.Cushing’s syndrome (CS) is the constellation of signs and symptoms resulting from excessive exposure to cortisol (1). While exogenous CS is relatively common, endogenous CS accounts for only 2.3 to 3.2 new cases per million per year; 10% of these present in children (2–4). Endogenous CS is...

Brief Summary: This study demonstrates that FADS2 is a major regulator of steroidogenesis in the adrenal gland due to its key role in shaping the lipidomic landscape of adrenocortical cells.Comment: The corticosteroids aldosterone and cortisol are produced in the zona glomerulosa and zona fasciculata of the adrenal cortex, respectively (1, 2). Excess production of aldosterone in primary hyperaldosteronism results in resistant hypertension and cardiovascu...

After binding and internalization, PCSK9 directs the LDL receptor to lysosomal degradation and inhibits its recycling to the cell surface, and thus accelerates the degradation of hepatic LDL receptors. This reduces the ...
