To read the full abstract: J Clin Endocrinol Metab. 2018 Feb 1;103(2):649-659A minimum level of energy availability is required for the onset of puberty, whereas increased fat mass has been shown to be associated with precocious onset of puberty1,2. Recent genome-wide association studies have identified several loci for age at menarche also associated with obesity3-5. Whethe...

To read the full abstract: Cell Rep. 2018; 22(5): 1236-1249Primary or secondary adrenal insufficiency (AI) results from adrenal failure or impairment of the hypothalamic-pituitary axis, respectively. The most frequent cause of primary AI is autosomal recessive congenital adrenal hyperplasia (CAH). Patients with AI need life-long treatment with exogenous steroids, which can be challenging, ...
