Background: Antioxidants and dietary fiber are postulated to have preventive effects on diabetic retinopathy, but evidence is lacking. We investigated this association in a cohort with type 2 diabetes 40–70 years of age hemoglobin (Hb)A1C ≥6.5%, originally part the Japan Diabetes Complications Study. Methods: After excluding people who did not respond survey patients retinopathy or major ocular disease at baseline, we analyzed 978 patients. Baseline intake was assessed by food frequency...

Background Machine learning (ML) algorithms have been widely introduced to diabetes research including those for the identification of hypoglycemia. Objective The objective this meta-analysis is assess current ability ML detect hypoglycemia (ie, alert coinciding with its symptoms) or predict before symptoms occurred). Methods Electronic literature searches (from January 1, 1950, September 14, 2020) were conducted using Dialog platform that covers 96 databases peer-reviewed literature....

Although conventional interventions for people at high risk of developing type 2 diabetes are usually conducted face-to-face, such burdensome health care providers. We developed a lifestyle intervention program combining coaching via smartphone application augmented by intermittently scanned continuous glucose monitoring without burdening Its effectiveness glycemic control and body weight reduction in was investigated.

Obesity is a metabolic and cardiovascular risk factor. A low calorie diet (LCD) one of the treatment modalities for weight loss. Serum advanced glycation end products (AGEs) are linked to increased atherogenicity inflammation in diseases such as diabetes renal failure. has an inflammatory component, but interestingly there no studies on serum AGE levels obesity or effects LCD therapeutic measure these markers glycation.We hypothesized that loss by caloric restriction beneficial effect...
