Prognostic Value of F-Fluorodeoxyglucose PET/Computed Tomography in Non-Small-Cell Lung Cancer.

Non-small cell lung cancer (NSCLC) is a leading cause of cancer-related death with a poor prognosis. Numerous factors contribute to treatment outcome. 18F-fluorodeoxyglucose (FDG) uptake reflects tumor metabolic activity and is an important prognosticator in patients with NSCLC.

Diabetes recurrence after metabolic surgeries correlates with re-impaired insulin sensitivity rather than beta-cell function.

Aim: To investigate factors causing diabetes recurrence after sleeve gastrectomy (SG) and duodenal-jejunal bypass (DJB).

Methods: SG and DJB were performed on rats with diabetes induced by high-fat diet (HFD) and streptozotocin (STZ). HFD was used to induce diabetes recurrence at 4 wk postoperatively.

Effects of sleeve gastrectomy plus trunk vagotomy compared with sleeve gastrectomy on glucose metabolism in diabetic rats.

Aim: To investigate the effects of sleeve gastrectomy plus trunk vagotomy (SGTV) compared with sleeve gastrectomy (SG) in a diabetic rat model.

Methods: SGTV, SG, TV and Sham operations were performed on rats with diabetes induced by high-fat diet and streptozotocin. Body weight, food intake, oral glucose tolerance test, homeostasis model assessment of insulin resistance (HOMA-IR), hepatic insulin signaling (IR, IRS1, IRS2, PI3K and AKT), oral glucose stimulated insulin secretion, GLP-1 and ghrelin were compared at various postoperative times.
