Article Synopsis
  • Gallstone disease significantly strains healthcare resources, particularly through emergency cholecystectomy, yet there's limited research on the risk factors that lead to such emergencies in patients scheduled for elective surgery.
  • A study conducted in Jeddah, Saudi Arabia, analyzed 823 patients, revealing that 15.67% underwent emergency cholecystectomy, often due to longer waiting times and previous emergency department visits.
  • Key findings indicated that patients with acute cholecystitis or pancreatitis, and those with multiple prior ED visits, are at a much higher risk of requiring emergency surgery.

Diabetes is a known inducer of hepatic ultrastructural alterations, and the expression of the immune biomarker that involves in T-cell immunity, cluster of differentiation 86 (CD86) is increased in diabetic patients with liver cirrhosis. The antidiabetic drug metformin has not previously been used to protect against type 2 diabetes mellitus (T2DM)-induced alternations in hepatic ultrastructure and the induction of the hepatic CD86/inflammation axis in diabetic animal models induced by streptozotocin and a high fat diet. To test our hypotheses, T2DM was induced in rats (model group) and the protective animals were treated with the antidiabetic drug metformin (200 mg/kg) until being sacrificed at week 12.

The discovery of cancer-specific biomarkers has resulted in major advancements in the field of cancer diagnostics and therapeutics, therefore significantly lowering cancer-related morbidity and mortality. Cancer biomarkers can be generally classified as prognostic biomarkers that predict specific disease outcomes and predictive biomarkers that predict disease response to targeted therapeutic interventions. As research in the area of predictive biomarkers continues to grow, precision medicine becomes far more integrated in cancer treatment.
