Introduction: Pregnancy involves distinct metabolic stages, initially characterized by maternal anabolism, followed by a catabolic phase driven by placental lactogen and various cytokines, leading to varying degrees of insulin resistance. DM is the most common metabolic disorder linked to pregnancy.Objective: The study aimed to detail the clinical characteristics, obstetric complications, and neonatal outcomes of patients with GDM and their children....

Introduction: T2DM is associated with an increased risk of fractures. This heightened risk is attributed to factors such as prolonged disease duration and chronic glycemic control. Interestingly, despite this increased fracture risk, patients with T2DM often exhibit normal or even elevated BMD compared to non-diabetic individuals. This phenomenon is thought to be a result of reduced bone remodeling, coupled with changes in bone microarchitecture.Objectiv...

TSH-secreting pituitary adenomas (thyrotropinomas or TSH-omas) are rare. At diagnosis, TSH-omas are frequently macroadenomas presenting with variable symptoms, and signs of hyperthyroidism. Somatostatin analogs (SSA) are a very efficient treatment to improve clinical signs in patients with TSH-omas, reducing hormone levels (90%) and causing tumor shrinkage (50%).Inhibitory effects of SSA are mediated by a family of five somatostatin receptor subtypes (sst1-5), with sst2 and ss...

Ghrelin was isolated from stomach by its ability to stimulate growth hormone (GH) release through the GH-secretagogue receptor (GHS-R1a). However, ghrelin/GHS-R expression in multiple tissues and tumor types suggested additional roles for this tandem. Ghrelin, a 28-aminoacid peptide, requires a unique O-acylation at its Ser-3 residue to bind GHS-R1a and release GH. Conversely, unacylated ghrelin (UAG), initially considered inactive, seems to play distinct metabolic role...

Ghrelin is a 28-aa peptide originally isolated from stomach but present also in many tissues, including hypothalamus and pituitary, where it stimulates growth hormone (GH) release through the ghrelin/GH secretagogue receptor (GHS-R). Ghrelin also increases food intake and adiposity and could play a key integrative role in the endocrine–metabolic interface. Although its primary pituitary cell target are somatotropes, ghrelin also modulates other pituitary cell types, speci...
