Review Meta AnalysisPerioperative noninvasive ventilation in obese patients: a qualitative review and meta-analysis.
Perioperative noninvasive ventilation (NIV) has been proposed to reduce postoperative morbidity and improve perioperative outcomes in patients undergoing general anesthesia. Whether it is advantageous to apply NIV just before and after general anesthesia in obese patients has not been yet established. ⋯ Results from this review and meta-analysis suggest that NIV is well tolerated and effective in improving perioperative care in obese patients. The application of NIV before and after general anesthesia should be considered and promoted in relevant cases.

Review Practice GuidelineLipids and bariatric procedures Part 2 of 2: scientific statement from the American Society for Metabolic and Bariatric Surgery (ASMBS), the National Lipid Association (NLA), and Obesity Medicine Association (OMA).
Bariatric procedures generally improve dyslipidemia, sometimes substantially so. Bariatric procedures also improve other major cardiovascular risk factors. ⋯ Part 1 was published in the Journal of Clinical Lipidology, and reviewed the impact of bariatric procedures upon adipose tissue endocrine and immune factors, adipose tissue lipid metabolism, as well as the lipid effects of bariatric procedures relative to bile acids and intestinal microbiota. This Part 2 reviews: (1) the importance of nutrients (fats, carbohydrates, and proteins) and their absorption on lipid levels; (2) the effects of bariatric procedures on gut hormones and lipid levels; (3) the effects of bariatric procedures on nonlipid cardiovascular disease (CVD) risk factors; (4) the effects of bariatric procedures on lipid levels; (5) effects of bariatric procedures on CVD; and finally, (6) the potential lipid effects of vitamin, mineral, and trace element deficiencies, that may occur after bariatric procedures.

Comparative Study Observational StudyThe impact of bariatric surgery on retinopathy in patients with type 2 diabetes: a retrospective cohort study.
The impact of bariatric surgery on diabetic retinopathy (DR) is unclear. DR might improve after surgery because of improvement in DR risk factors, but the rapid improvement in hyperglycemia after surgery could worsen DR. ⋯ After bariatric surgery, patients with T2DM remain at risk for developing STDR, even those who did not have evidence of DR before surgery. However, surgery was associated with a lower progression to STDR or maculopathy compared with routine care. Randomized clinical trials are needed to ascertain the impact of bariatric surgery on DR.

Influence of intraoperative hypotension on leaks after sleeve gastrectomy.
Leak after a sleeve gastrectomy (SG) is a severe complication. Risk factors, such as regional ischemia, increased intraluminal pressure, technical failure of the stapling device, and surgeon error, have been reported. ⋯ Intraoperative hypotension may contribute independently to a leak after SG.
