The effect of sucralfate on gastric emptying, gastric mucus production, and ulcer formation in cold-restraint rats was studied. The rats were treated with sucralfate in doses of 100 mg/kg, 250 mg/kg and 500 mg/kg. Sucralfate prevented ulcer formation dose dependently. This effect was maximum at doses of 500 mg/kg (P < 0.001). Administration of sucralfate lowered the increased gastric emptying rate and increased gastric mucus production. This effect was not dose dependent. It was found that the ulcer-preventive effect of sucralfate was due to a lowered gastric emptying rate and increased mucus production in addition to other mechanisms.

Introduction: Pancreatoduodenectomy (PD) is a complex surgery with high morbidity and mortality, often associated with complications like post-pancreatectomy hemorrhage (PPH) and postoperative pancreatic fistulas (POPF). The corticosteroids administered intraoperatively has been shown to improve postoperative outcomes in patients undergoing surgery. However, their impact on complications following PD remains controversial.

Type 2 diabetes mellitus (T2DM) and obesity are critical global health issues with rising incidence rates. Glucagon-like peptide-1 (GLP-1) analogues have emerged as effective treatments due to their ability to regulate blood glucose levels and gastric emptying through central nervous signals involving hypothalamic receptors, such as leptin. To address the short plasma half-life of native GLP-1, a C-16 fatty acid was conjugated to lysine in the GLP-1 analogue sequence to enhance its longevity.

Obesity significantly influences drug pharmacokinetics (PK), which challenges optimal dosing. This study examines the effects of diet-and-exercise-induced weight loss on key drug-metabolizing enzymes and gastric emptying in patients with obesity, who frequently require medications for comorbidities. Participants followed a structured weight management program promoting weight loss over 3-6 months and were not concomitantly on potential CYP inducers or inhibitors.

The nutritive value of a protein is determined not only by its amino acid composition, but also by its digestibility in the gastrointestinal tract. The interaction between proteins and pepsin in the gastric stage is the first step and plays an important role in protein hydrolysis. Moreover, it affects the amino acid release rates and the allergenicity of the proteins.

Background: Glucagon-like peptide-1 receptor agonist (GLP-1RA) therapies are increasingly used for the treatment of type 2 diabetes mellitus and obesity. Despite growing awareness of potentially increased risk of pulmonary aspiration due to delayed gastric emptying, the risks and benefits of their perioperative use in patients undergoing cardiac procedures remains unexplored. A scoping review was performed to investigate the perioperative GLP-1RA use in patients undergoing cardiac procedures and recommendations.
