This study evaluated the effectiveness of panretinal photocoagulation (PRP) plus intravitreal anti-VEGF treatment versus PRP alone for the treatment of patients with diabetic retinopathy (DR; diabetic eye disease). The data showed that PRP with anti-VEGF combination treatment improved vision without an increase in side effects compared to PRP alone in these patients.

This study evaluated the long-term effects of a moderate low-carbohydrate diet (LCD) on blood glucose control and liver function in patients with type 2 diabetes (T2D). The data showed that patients on a moderate LCD diet showed better blood glucose control and liver function over the long term than patients on a traditional diabetic diet (TDD).

This study evaluated the effectiveness, durability, and safety of faricimab (Vabysmo) for the treatment of patients with diabetic macular edema (DME). The data showed that faricimab with extended dosing up to every 16 weeks was safe and showed good vision gains and clinical improvements in these patients.

This study compared the effects of a ketogenic diet mobile health application (Keyto app) with breath acetone biofeedback (device) versus a calorie-restricted, low-fat diet (WW; weight watchers) app on weight loss and metabolic risk in patients with overweight or obesity. The data showed that a ketogenic diet app with a breath acetone biofeedback device was more effective in promoting weight loss than a calorie-restricted, low-fat diet app in these patients. 

This study determined the effect of varying carbohydrate and saturated fat dietary contents on cardiovascular disease (CVD) risk factors during weight-loss maintenance. The authors concluded that restriction of carbohydrates provided improved insulin resistance on lipoprotein metabolism, without unwanted side effects on low-density lipoprotein (LDL) cholesterol or inflammation.

This study observed the effectiveness of a ketogenic diet (KD) in patients newly diagnosed with type 2 diabetes (T2D) that were overweight or obese. The authors concluded that a DK can control body weight, blood glucose, and blood lipids (fats) in these patients but long-term adherence is a challenge.

This study assessed the safety and effectiveness of oral, high-dose daily vitamin D3 for the prevention of diabetes in adults at high risk for type 2 diabetes (T2D). The authors concluded that oral, high-dose daily vitamin D3 at a dose of 4000 IU was safe and well-tolerated in patients with prediabetes that were overweight or obese.

This study assessed the link between metformin (Glucophage) use in hospitalized and non-hospitalized patients with diabetes and different outcomes due to coronavirus disease 2019 (COVID-19). The study showed that metformin use was associated with a protective effect in COVID-19 outcomes in patients with type 2 diabetes (T2D).

This study evaluated the long-term relationship between bariatric surgery (BS; weight loss surgery) and major adverse cardiovascular events (MACE) in patients with obesity, diabetes, and hypertension (high blood pressure; BP). The study showed that a sustained decrease in MACE occurrence was associated with BS in these patients.

This study evaluated the effect of whole grain consumption in glycaemic (blood sugar) control of patients with diabetes. The data showed that whole grain consumption was beneficial for the control of blood glucose levels in these patients.
