Evaluating remission of type 2 diabetes using a metabolic intervention including fixed-ratio insulin degludec and liraglutide: A randomized controlled trial.

AIM: To evaluate the effect on type 2 diabetes remission of short-term intensive metabolic intervention consisting of frequent dietary, exercise and diabetes management coaching, metformin and fixed-ratio insulin degludec/liraglutide. METHODS: In a multicentre open-label randomized controlled trial, insulin-naïve participants within 5 years of diabetes diagnosis were assigned to a 16-week remission intervention regimen or standard care, and followed for relapse of diabetes and sustained remission for an additional year after stopping glucose-lowering drugs. RESULTS: A total of 159 participants aged 57 ± 10 years, with diabetes duration 2.6 ± 1.5 years, body mass index 33.5 ± 6.5 kg/m2, and glycated haemoglobin (HbA1c) level 53 ± 7 mmol/mol were randomized and analysed (79 intervention, 80 control). At the end of the 16-week intervention period, compared to controls, intervention participants achieved lower HbA1c levels (40 ± 4 vs. 51 ± 7 mmol/mol; p < 0.0001), and lost more weight (3.3 ± 4.4% vs. 1.9 ± 3.0%; p = 0.02). There was a lower hazard of diabetes relapse overall in the intervention group compared to controls (hazard ratio 0.63, 95% confidence interval [CI] 0.45, 0.88; p = 0.007), although this was not sustained over time. Remission rates in the intervention group were not significantly higher than in the control group at 12 weeks (17.7% vs. 12.5%, relative risk [RR] 1.42, 95% CI 0.67, 3.00; p = 0.36) or at 52 weeks (6.3% vs. 3.8%, RR 1.69, 95% CI 0.42, 6.82) following the intervention period. CONCLUSIONS: An intensive remission-induction intervention including fixed-ratio insulin degludec/liraglutide reduced the risk of type 2 diabetes relapse within 1 year without sustained remission.

The transcultural diabetes nutrition algorithm: a canadian perspective.

The Transcultural Diabetes Nutrition Algorithm (tDNA) is a clinical tool designed to facilitate implementation of therapeutic lifestyle recommendations for people with or at risk for type 2 diabetes. Cultural adaptation of evidence-based clinical practice guidelines (CPG) recommendations is essential to address varied patient populations within and among diverse regions worldwide. The Canadian version of tDNA supports and targets behavioural changes to improve nutritional quality and to promote regular daily physical activity consistent with Canadian Diabetes Association CPG, as well as channelling the concomitant management of obesity, hypertension, dyslipidemia, and dysglycaemia in primary care. Assessing glycaemic index (GI) (the ranking of foods by effects on postprandial blood glucose levels) and glycaemic load (GL) (the product of mean GI and the total carbohydrate content of a meal) will be a central part of the Canadian tDNA and complement nutrition therapy by facilitating glycaemic control using specific food selections. This component can also enhance other metabolic interventions, such as reducing the need for antihyperglycaemic medication and improving the effectiveness of weight loss programs. This tDNA strategy will be adapted to the cultural specificities of the Canadian population and incorporated into the tDNA validation methodology.

Impact of admission serum glucose level on in-hospital outcomes following coronary artery bypass grafting surgery.

OBJECTIVE: The impact of admission serum glucose (SG) level on outcomes in coronary artery bypass grafting (CABG) surgery is unknown. The present study sought to determine whether elevated admission SG level is associated with adverse outcomes following CABG surgery. METHODS: Patients undergoing CABG surgery between January 2000 and December 2005 at a single centre were identified (n=2856). Admission SG levels of less than 9.2 mmol/L and 9.2 mmol/L or greater were chosen to divide patients into two groups based on the 75th percentile of SG distribution. A logistic regression model was generated to determine the impact of admission SG level on a composite outcome of any one or more of in-hospital mortality, stroke, perioperative myocardial infarction, sepsis, deep sternal wound infection, renal failure, requirement for postoperative inotropes and prolonged ventilation. RESULTS: In total, 76.3% of patients had an admission SG level of less than 9.2 mmol/L (group A) and 23.7% had an admission SG level of 9.2 mmol/L or greater (group B). Group B patients were more likely to be female, have diabetes, have preoperative renal failure, have an ejection fraction of less than 40%, experience myocardial infarction within 21 days before surgery, and have triple vessel or left main disease (P<0.05). Univariate analysis revealed no difference in in-hospital mortality between group A (2.2%) and group B (3.2%) (P=0.12); however, the composite outcome was more likely to occur in group B (40.8%) versus group A (27.9%) (P=0.0001). After multivariable adjustment, admission SG level of 9.2 mmol/L or greater remained an independent predictor of composite outcome (OR=1.3, 95% CI 1.0 to 1.7, P=0.02, receiver operating characteristic = 78%). CONCLUSION: Admission SG level of 9.2 mmol/L or greater is associated with significant morbidity in patients undergoing CABG surgery.

Anemia is an independent risk for mortality after acute myocardial infarction in patients with and without diabetes.

INTRODUCTION: Anemia and diabetes are risk factors for short-term mortality following an acute myocardial infarction(AMI). Anemia is more prevalent in patients with diabetes. We performed a retrospective study to assess the impact of the combination of diabetes and anemia on post-myocardial infarction outcomes. METHODS: Data relating to all consecutive patients hospitalized with AMI was obtained from a population-based disease-specific registry. Patients were divided into 4 groups: diabetes and anemia (group A, n = 716), diabetes and no anemia (group B, n = 1894), no diabetes and anemia (group C, n = 869), and no diabetes and no anemia (group D, n = 3987). Mortality at 30 days and 31 days to 36 months were the main outcome measures. RESULTS: 30-day mortality was 32.3% in group A, 16.1% in group B, 21.5% in group C, 6.6% in group D (all p < 0.001). 31-day to 36-month mortality was 47.6% in group A, 20.8% in group B, 34.3% in group C, and 10.4% in group D (all p < 0.001). Diabetes and anemia remained independent risk factors for mortality with odds ratios of 1.61 (1.41-1.85, p < 0.001) and 1.59 (1.38-1.85, p < 0.001) respectively at 36 months. Cardiovascular death from 31-days to 36-months was 43.7% of deaths in group A, 54.1% in group B, 47.0% in group C, 50.8% group D (A vs B, p < 0.05). INTERPRETATION: Patients with both diabetes and anemia have a significantly higher mortality than those with either diabetes or anemia alone. Cardiovascular death remained the most likely cause of mortality in all groups.
