Effect of Bariatric Surgery on Cardiovascular Events and Metabolic Outcomes in Obese Patients with Insulin-Treated Type 2 Diabetes: a Retrospective Cohort Study

AbstractAimsTo compare non-fatal cardiovascular (CV) events and metabolic outcomes, among obese patients with insulin-treated type 2 diabetes who underwent bariatric surgery compared with a propensity-matched non-bariatric cohort.MethodsA retrospective cohort study was conducted among 11,125 active patients with type 2 diabetes from The Health Improvement Network (THIN) database. Propensity score matching (up to 1:6 ratio) was used to identify patients who underwent bariatric surgery (N = 131) with a non-bariatric cohort (N = 579). Follow-up was undertaken for 10 years (9686 person-years) to compare differences in metabolic outcomes and CV risk events that included the following: acute myocardial infarction (AMI), stroke, coronary heart disease (CHD), heart failure (HF) and peripheral artery disease (PAD). Cox pr oportional regression was used to compute the outcomes between groups.ResultsThe mean age was 52 (SD 13) years (60% female); the baseline weight and BMI were 116 (SD 25) kg and 41 (SD 9) kg/m2, respectively. Significant reductions in weight and BMI were observed in bariatric group during 10  years of follow-up. Bariatric surgery had a significant cardioprotective effect by reducing the risk of non-fatal CHD (adjusted hazard ratio [aHR] 0.29, 95% CI 0.16–0.52,p

In conclusion, children younger than 5 years, especially boys, were vulnerable groups for pandemic influenza, presenting as a mild disease with low mortality and few complications. Most of the affected children with influenza did not have important risk factors such as asthma and obesity, highlighted by other authors as significant risk factors.

This study has been carried out to examine the effect of SSF by Rhizopus oryzae on the bioactive content, bioactivity, bioaccessibility and bioavailability of 4 different varieties of rice bran. In vitro digestion with dialysis was carried out to assess the bioavailability and bioaccessibility of rice bran bioactives. Methanolic extracts and digested fractions of fermented and unfermented rice brans were analyzed for total phenolic (TPC), flavonoid (TF), carotenoid (TC), and total anthocyanin content (TAC). Additionally, antioxidant activity, anti-inflammatory property and the anti-diabetic property was also evaluated. The...

It has therapeutic impacts over wide range of diseases, especially the ones related to oxidative stress. Resveratrol, being primarily a potent anti-oxidant phytochemical, has significant impact against major diseases as inflammatory disorders, diabetes, and cancer. In the current review article, we intend to highlight the molecular aspects of the mechanism of action of resveratrol against major diabetic implications, namel...

P6Q also abolishes cerebral hemorrhage induced by ischemia with tissue plasminogen activator (tPA). In the present study we examined the beneficial effects of P6Q on other post-stroke prognostic psychology-related symptoms, which obstruct the motivation toward physical therapy.
