Filter by:The objective of the study is to quantify the relationship between physical activity, metabolic function, and appetite in adolescents. To do this we will test our working hypothesis that high levels of regular moderate-to-vigorous physical activity (MVPA), as opposed to body weight status, results in a metabolic phenotype consisting of enhanced metabolic function and proper regulation of appetite. We will randomly assigning sedentary overweight/obese adolescents (N=44) to either a control or structured-exercise group for three months.
Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of saccharin, but not acesulfame potassium, in middle-aged/older adults with prediabetes compared to a eucaloric diet with no NNS.
The main objective of the study is to evaluate the effects of daily honey consumption on insulin resistance as a preventive measure against diabetes. in women with insulin resistance.
The objective of this work is to identify biomarkers of interest in patients with insulin resistance leading to early disorders of glycemic regulation. For this the investigators want to assay the insulin resistance marker Insulin Regulated Amino Peptidase serique (IRAPs), the plasma lipidome and inflammation markers in 2 populations of insulin-resistant subjects due to Dunnigan's inherited lipodystrophy or overweight/obesity and insulin-sensitive subjects with or without a glycemic regulation disorder objectified during an Oral induced hyperglycemia. The results of the IRAPs, lipidome and inflammation assays will be compared in insulin-resistant subjects, between normoglycemic, prediabetic and diabetic subjects. Correlations will be made between these markers and the deterioration of glycemic regulation as well as with known insulin resistance parameters (HOmeostasis Assessment Model (HOMA), Quantitative Insulin-sensitivity Check Index (QUICKI),Insulin Sensitivity Index (Isi) MATSUDA).
The objective of the study is to determine the effect of dairy consumption on insulin sensitivity in overweight and obese adults with prediabetes. Men and women (30-65 y) will be recruited from the greater Montreal area. Upon screening, those with prediabetes will complete a 2-wk run-in period in which participants will consume 1 serving/d of reduced-fat dairy. Adherent participants will be randomized by sex into 1 of 3 groups: ≤1 serving/d of dairy (limited dairy) or 2-3 servings/d of reduced-fat or regular-fat dairy for 12 weeks. Participants will be instructed on how to incorporate foods into their diet in a manner that prevents changes in their body weight. The hyperinsulinemic-euglycemic clamp will be used before and after the intervention to document potential changes in insulin sensitivity as the primary outcome. In addition, glycemic variables, body composition, and cardiometabolic risk factors will be assessed as secondary outcomes. Serum lipidomic and global gene expression responses to the intervention in subcutaneous adipose tissue will be measured as exploratory variables. Adherence to intervention will be assessed at each visit by food diaries, a record of consumed dairy products, and serum proportion of 15:0, 17:0, and t16:1n7 fatty acids as objective biomarkers of dairy fat intake.
The investigators aim to evaluate the effect of curcumin and virgin coconut oil extract supplementation on people with type 2 DM, including blood glucose, HbA1c levels, inflammation, body weight and insulin resistance evaluation
The purpose of this research study is to determine whether continuous glucose monitors (CGM) are a safe, effective, and acceptable way to evaluate type 2 diabetes risk in youth as compared to the standard 2-hour oral glucose tolerance test (OGTT). This study will involve wearing a CGM, wearing a physical activity tracker, responding to surveys, and completing at-home glucose and mixed food challenge while wearing the CGM. Subjects will also be asked to complete an interview by phone or videoconference after wearing the CGM.
The main objective of this study is to evaluate the evolution of the sensitivity to insulin, a hormone that acts on sugar in the body, as well as other metabolic, motor and nutritional elements of children with cancer, according to the practice of intense physical activities or stretching. In view of the scientific work on this subject, it is expect to observe that the practice of intense physical activities will improve the results of the children in the metabolic, motor and nutritional evaluations, compared to the stretching program.
In this project the investigators intend to study the therapeutic potential of a personalized fibre mixture in individuals at high risk of developing T2DM, and aim to address the following key objectives: 1. To investigate whether a mixture of fermentable fibres, which differ in DP and side chains, will stimulate a broad range of SCFA-producing bacterial genera, resulting in enhanced chronic SCFA production throughout the whole colon with a large variation between individuals; 2. To unravel whether providing personalized fibre mixtures, selected based on the individuals' initial microbiota and capacity for SCFA production is crucial to successfully improve host insulin sensitivity and metabolic health
Helicobacter pylori is a common pathogen causing upper gastrointestinal diseases including gastric ulcer and gastric cancer. Recent epidemiological findings have also shown that it is also related to colon cancer, metabolic syndrome, gut dysbiosis, glycemic control and insulin resistance. The aim of this study is to investigate whether the gut microbiota and insulin resistance of patients with H. pylori infection are abnormal. In addition, whether drinking fermented milk product with probiotic reduces Helicobacter pylori, improves gut microbiota, and increases butyrate-producing bacteria and insulin resistance.
