Aims: To develop a model for simulations of processes in the oral glucose tolerance test (OGTT), using tools of the theory of dynamic systems.
Methods: Frequent sampling OGTT was performed in 13 healthy subjects (6 males and 7 females). Subsequently, employing glucose and insulin concentration-time profiles of the subjects, the model was developed.
Results: In all subjects the model was able to simulate influences of the insulin plasma concentration and gastric emptying rate on glucose concentration and to determine time profiles of glucose fractions retained in stomach.
Conclusions: The approach presented represents an opportunity for building models for data analyses in OGTT.

Risk factors for delayed gastric emptying after pancreatoduodenectomy: a 10-year retrospective study.
Ann Med
December 2025
Department of Surgery, Faculty of Medicine, Unit of Hepato-Pancreato-Biliary Surgery and Abdominal Organ Transplantation, Doce de Octubre University Hospital, Instituto de Investigación (imas12), Complutense University, Madrid, Spain.
Background: Delayed gastric emptying (DGE) is a frequent complication of pancreatoduodenectomy (PD) and is associated with prolonged hospital stay, readmission, increased hospital costs and decreased quality of life. However, the pathophysiology of DGE remains unclear.
Methods: This is a retrospective study of patients who underwent PD for pancreatic or periampullary tumours.
Effect of lactic acid-rich sourdough bread on appetite regulation: A randomized, double-blind controlled trial.

Translational Research Center in Gastrointestinal Disorders (TARGID), Department of Chronic Diseases and Metabolism, Medicine, KU Leuven, Leuven, Belgium.
Sourdough bread consumption has been associated with improved glucose and appetite regulation thanks to the presence of organic acids produced during fermentation of the flour-water mixture. We investigated the effects of whole meal sourdough bread (WSB) rich in lactic acid on energy intake, satiety, gastric emptying, glucose, and C-peptide response compared to whole meal yeast bread (WYB). Forty-four normal-weight participants (age: 30 ± 10 y; BMI: 23 ± 2 kg/m) participated in this double-blind, randomized cross-over trial, consisting of two study visits separated by one week.

Introduction: Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) have been diagnosed increasingly often but still represent rare pancreatic neoplasms. Surgery is a potentially curative approach for patients with NF-PNETs. In recent years, minimally invasive surgery (MIS) has been applied more frequently for surgical resection of NF-PNETs.

Background: Laparoscopic distal pancreatectomy is a safe and effective surgical method for treating benign and malignant tumors of the pancreatic body and tail. However, laparoscopic surgery requires good intraoperative exposure, and since the pancreas is obstructed by the stomach and duodenum, making surgical operations and the management of intraoperative emergencies challenging. Therefore, gastric traction is crucial in laparoscopic distal pancreatectomy.

Gastric ulcers often cause postprandial epigastric pain, especially in acute cases. Abnormal motility, with about 50 % of patients having delayed gastric emptying, contributes to ulcer development. Costunolide (COS) and dehydrocostuslactone (DEH), derived from "Mu xiang" herbs, show potential in treating ulcers and regulating gastrointestinal motility.
