Circadian copeptin and oxytocin profiles in anorexia nervosa: Exploring the interplay with neurohypophysis opioid tone.

Context: Neurohypophysis (NH) function in eating disorders (ED) remains poorly elucidated. Studies on vasopressin and oxytocin display inconclusive findings regarding their levels and associations with psychological complications in ED. The profile of opioid tone, a crucial NH activity regulator, is also unknown.

Structure-function relationship of the pituitary gland in anorexia nervosa and intense physical activity.

Patients with Anorexia Nervosa (AN) and athletes share intense physical activity and pituitary hormonal disturbances related to absolute (AN) or relative (athletes) undernutrition. Pituitary gland (PG) structure evaluations in those conditions are scarce, and did not differentiate anterior from posterior lobe. We evaluated the structure-function relationship of anterior and posterior PG in AN and athletes, and potential reversibility of this alteration in a group of weight-recovered patients (AN_Rec).

Genome Sequences of the Delta Variant (B.1.617.2) and the Kappa Variant (B.1.617.1) Detected in Morocco.

Here, we report the identification and coding-complete genome sequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains obtained from patients with COVID-19. The strains identified belong to variant of concern B.1.

[Longitudinal sleeve gastrectomy as a stand-alone bariatric procedure: Results of a multicenter retrospective study].

Introduction: Sleeve gastrectomy as an isolated procedure is a new option in bariatric surgery. The aim of this study was to evaluate its short and medium term (2 years) results in a multicenter setting.

Materials: This is a retrospective study including 446 patients undergoing surgery in 14 teaching, private, and public hospitals.
