Physical exercise is an important component in the management of type 1 diabetes across the lifespan. Yet, acute exercise increases the risk of dysglycaemia, and the direction of glycaemic excursions depends, to some extent, on the intensity and duration of the type of exercise. Understandably, fear of hypoglycaemia is one of the strongest barriers to incorporating exercise into daily life. Risk of hypoglycaemia during and after exercise can be lowered when insulin-dose adjustments are made and/or additional carbohydrates are consumed. Glycaemic management during exercise has been made easier with continuous glucose monitoring (CGM) and intermittently scanned continuous glucose monitoring (isCGM) systems; however, because of the complexity of CGM and isCGM systems, both individuals with type 1 diabetes and their healthcare professionals may struggle with the interpretation of given information to maximise the technological potential for effective use around exercise (i.e. before, during and after). This position statement highlights the recent advancements in CGM and isCGM technology, with a focus on the evidence base for their efficacy to sense glucose around exercise and adaptations in the use of these emerging tools, and updates the guidance for exercise in adults, children and adolescents with type 1 diabetes.
Aim
To investigate once‐weekly (OW) semaglutide, a glucagon‐like peptide‐1 receptor agonist (GLP‐1RA), in patients with type 2 diabetes (T2D) in routine clinical practice.
Methods
The SURE Canada study was a multicenter, prospective, observational study. Adults with T2D and one or more documented HbA1c values 12 weeks or less before semaglutide initiation were enrolled. The primary endpoint was change in HbA1c from baseline to end of study (EOS; ~30 weeks). Secondary endpoints included change in body weight (BW), waist circumference and patient‐reported outcomes (PROs) and the proportion of patients achieving HbA1c of less than 7.0%, weight loss (WL) of 5% or higher, and a composite of HbA1c reduction of 1% or higher and WL of 3% or higher at EOS. Data were analysed and presented for patients on semaglutide at EOS overall and for the following baseline medication subgroups: oral antihyperglycaemic drugs (OADs) only; GLP‐1RA experienced; insulin ± OADs without GLP‐1RA.
Results
In total, 452 patients initiated semaglutide and 356 completed the study on treatment. For the 452 patients, mean baseline HbA1c was 8.1%; 86 (19.0%) patients had HbA1c of less than 7.0%. Mean dose of semaglutide at EOS was 0.76 ± 0.31 mg. Mean HbA1c was reduced by 0.9%‐point (95% confidence interval [CI]: 0.97; 0.78). Mean BW was reduced by 4.3 kg (95% CI: 4.79; 3.76). At EOS, 46.9% of patients achieved HbA1c of less than 7.0%, 40.9% achieved WL of 5% or higher and 24.1% achieved the composite endpoint. PROs improved from baseline to EOS. No new safety concerns were reported.
Conclusions
In SURE Canada, patients treated with OW semaglutide in routine clinical practice experienced clinically significant improvements in HbA1c, BW and other outcomes, supporting semaglutide use in routine clinical practice.
RationaleObesity/overweight is the most prevalent body composition abnormality in COPD. However, little is known about the impact of fat distribution on cardiometabolic health in COPD.ObjectiveTo study the associations between ectopic adiposity, cardiometabolic health, and COPD.MethodsA total of 263 subjects (166 males; age=65±9 years) were randomly selected from the general population. Subjects were classified as non-COPD controls and COPD, according to the Global initiative for chronic Obstructive Lung Disease (GOLD) classification, and the presence of cardiometabolic comorbidities was recorded. Ectopic fat accumulation was documented from computed tomography measurements of visceral adipose tissue cross-sectional areas and muscle mean attenuation, assessed at L4–L5. Blood glucose, lipid, and adipokine profiles were also evaluated.ResultsAfter correcting for age, sex, and tobacco exposure, visceral adipose tissue cross-sectional area was higher in GOLD 2+ compared to GOLD 1 individuals. Consistent with this, mean muscle tissue attenuation was lower in GOLD 2+ vs GOLD 1 and non-COPD controls (P<0.001). In multiple regression models, visceral adipose tissue cross-sectional area was strongly associated with hypertension (P<0.001) and diabetes (P<0.001), while muscle attenuation was associated with coronary artery disease (P<0.001). Blood glucose, lipid, and adipokine profiles were similar across groups with the exception of leptin level which was higher in GOLD 2+ subjects compared to GOLD 1 and controls.ConclusionGOLD 2+ COPD was associated with ectopic fat accumulation which modulated cardiometabolic health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
