This systematic review and meta-analysis of 126 randomised controlled trials, published in Diabetes Care, identified that the weekly dose of physical activity required to optimise glucose-lowering in people with type 2 diabetes is 1100 Metabolic Equivalents of Task (MET)-minutes per week, and this remained consistent across a wide range of baseline HbA1c values. This is the equivalent of 36 minutes per day of moderate-paced walking, 244 minutes of moderate-intensity aerobic activity per week or 318 minutes of moderate strength training per week. Multicomponent activity (a mix of strength and aerobic activity), strength training and brisk walking were the most effective activities. Achieving the optimal weekly MET dose had greater effects in those with higher HbA_1c at baseline, including up to a 1.02% reduction in those with an initial HbA1c >64 mmol/mol, and there was even a statistically significant 0.24–0.38% HbA_1c reduction in those with prediabetes (HbA1c <48 mmol/mol) at baseline. These findings suggest that people with diabetes may need more physical activity than in the current generic recommendations of 150–300 minutes per week of moderate-intensity activity or 75–150 minutes per week of vigorous activity. Since we know that many do not achieve current recommendations consistently, helping people undertake these doses of physical activity is likely to need support from a multidisciplinary team, including exercise professionals and coaches, as well as from family and friends.

      Metformin use during initiation and titration of GLP-1 receptor agonists (GLP-1 RAs) does not increase the frequency or severity of gut-related adverse events, or the likelihood of discontinuing the GLP-1 RA, according to this study published in Diabetes Care. Since gastrointestinal (GI) adverse events are common with both metformin and with GLP-1 RAs, data from four major clinical trials of liraglutide and subcutaneous and oral semaglutide were used to explore whether those treated with metformin suffered more GI side effects. The results suggest that pausing metformin therapy during GLP-1 RA initiation, as has been recommended by some, is not required. There was in fact a higher rate of GI adverse events and GLP-1 RA discontinuations in those not taking metformin, which the authors postulate could reflect an increased susceptibility to gut side effects with any drug. They recommend that increased counselling and consideration of slower titration may be helpful in this group. This is useful information to guide practice as a recently published National Drug Safety Alert states that supplies of oral semaglutide are now adequate to support new initiations of this drug, following the mandatory cessation of new initiations of any GLP-1 RA that has been in place since June 2023 due to manufacturing shortages.

This article explores the growing role of artificial intelligence (AI) in patient self care in diabetes and considers the opportunities and risks associated with it in the context of foot self care in diabetes. AI has yielded many advances in individual and public health, although it does also present unique and emergent challenges. Certainly, AI enables us to consider and re-evaluate diabetes care, screening and management.

Article points

1. Artificial intelligence has been shown to influence and improve certain aspects of diabetes care.

2. Self care and patient education are key to avoiding complications such as diabetic foot ulcers.

3. Artificial intelligence has as-yet unleashed potential in the field of foot self care and ulcer management, especially in the context of patient education and driving foot self-care behaviours.
