Clinical implications of DNA ploidy, stroma, and nucleotyping in predicting peritoneal metastasis risk for gastric cancer.
BMC Cancer
January 2025
Department of Gastrointestinal Surgery I Section, Renmin Hospital of Wuhan University, Wuhan, 430060, China.
Background: Gastric cancer peritoneal metastasis lacks effective predictive indices. This article retrospectively explored predictive values of DNA ploidy, stroma, and nucleotyping in gastric cancer peritoneal metastasis.
Methods: A comprehensive analysis was conducted on specimens obtained from 80 gastric cancer patients who underwent gastric resection at the Department of Gastrointestinal Surgery of Wuhan University Renmin Hospital.
Transomental hernia resulting in a closed loop small bowel obstruction: delayed presentation following paediatric blunt abdominal trauma.
BMJ Case Rep
January 2025
General Surgery, Toowoomba Hospital, Toowoomba, Queensland, Australia.
While internal hernias are rare in the paediatric population, it should be considered as a cause for an acute abdomen following blunt trauma. Internal hernias represent a surgical emergency that requires prompt recognition due to the high risk of strangulation and ischaemia of affected bowel loops. The case of a transomental hernia (TOH) is described in a young girl.

Institute of Cardiac and Aortic Disorders, SRM Institutes for Medical Science (SIMS Hospitals), Chennai, India.
Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

Introduction: Cold static storage (CSS) and normothermic ex-situ preservation are the most widely used donor heart preservation techniques worldwide. The current study compares both CSS and normothermic ex-situ preservation methods in terms of graft performance, morphologic changes, and acute immune response in an experimental model.
Method And Materials: Twenty rats underwent heterotopic abdominal heart transplantation after 2 h of CSS (group 1; n = 10) or normothermic ex-situ perfusion (group 2; n = 10).
