Relationship between perioperative semaglutide use and residual gastric content: A retrospective analysis of patients undergoing elective upper endoscopy.

Study Objective: Semaglutide is a long-acting glucagon-like peptide-1 receptor agonist used for management of type 2 diabetes and/or obesity. To test the hypothesis that perioperative semaglutide use is associated with delayed gastric emptying and increased residual gastric content (RGC) despite adequate preoperative fasting, we compared the RGC of patients who had and had not taken semaglutide prior to elective esophagogastroduodenoscopy. The primary outcome was the presence of increased RGC.

Carvedilol prevents ovariectomy-induced myocardial contractile dysfunction in female rat.

Carvedilol has beneficial effects on cardiac function in patients with heart failure but its effect on ovariectomy-induced myocardial contractile dysfunction remains unclear. Estrogen deficiency induces myocardial contractile dysfunction and increases cardiovascular disease risk in postmenopausal women. Our aim was to investigate whether carvedilol, a beta receptor blocker, would prevent ovariectomy-induced myocardial contractile dysfunction.

Myocardial contractile dysfunction induced by ovariectomy requires AT1 receptor activation in female rats.

Background/aim: Estrogen deficiency induces myocardial contractile dysfunction and increases cardiovascular disease risk. However, the mechanism underlying this response is unclear. Our aim was to investigate whether AT(1)receptor blockade would prevent ovariectomy-induced myocardial contractile dysfunction.
