Filter by:The primary objective is to investigate the effect of apple polyphenol supplementation for 12 weeks on glucose homeostasis in prediabetic individuals. Further, this study has three secondary objectives: 1) to investigate whether daily supplementation at breakfast and dinner with apple polyphenols for 12 weeks affects the rhythm of glucose uptake over the day and reduces fasting glucose levels and postprandial glucose peaks; 2) to determine the effect of daily supplementation with apple polyphenols for 12 weeks on biomarkers of metabolic health; 3) to assess whether daily supplementation with apple polyphenols for 12 weeks alters fecal SCFA concentrations and fecal microbiota composition.
This study will examine whether a physical activity program, specifically increasing walking steps, offered over the internet is able to increase physical activity in adults with prediabetes. The study will take place over 12 weeks. The investigators want to see if people who receive the intervention increase their physical activity more than people who do not receive the intervention. The physical activity program will include using a pedometer to track daily step counts online, set weekly goals, and receive motivational messages delivered weekly using email. The investigators are also going to collect data on waist circumference, body weight and quality of life at baseline, 12 weeks and 16 weeks after the intervention has completed to see if these change over the course of the study. The investigators will be recruiting 200 adults who have attended the Edmonton, Alberta prediabetes education class offered by Alberta Health Services, Nutrition Services and report they have prediabetes. If able to successfully increase physical activity, this study will identify a web and home-based intervention that can be offered to individuals who participate in lifestyle programs delivered in primary care settings (e.g., Edmonton prediabetes program) in both rural and urban locations.
Sensory dysfunction as a result of peripheral nerve damage is a significant problem that leads to reduced quality of life for patients. The prevalence of sensory dysfunction in peripheral neuropathy associates with epidemic increases in prediabetes and diabetes, but also is relevant to chemotherapy treatments and genetic disorders. Clinical approaches to treat peripheral neuropathy and to stimulate axon growth in settings of peripheral axon loss are limited. Although new drugs will hopefully be forthcoming, the most promising approaches likely involve behavioral and lifestyle interventions. Mitochondrial dysfunction is emerging as a key cellular contribution to peripheral axon health and peripheral neuropathy. Mitochondrial deficiencies contribute to neuropathy and include impaired mitochondrial problems with trafficking, mitophagy, fission, and biogenesis. All of these are thought to lead to a bioenergetic crisis, ending in distal axonal degeneration, sensory dysfunction and pain. Heat shock proteins play a critically important role in cellular homeostasis and increasing heat shock protein functions within cells leads to a range of positive improvements, particularly in mitochondria. In addition, new evidence suggests that increasing heat shock protein responses in peripheral nerves has powerful, positive impacts on sensory function and neuropathy. Our interdisciplinary team will investigate the role of mitochondrial dysfunction in peripheral neuropathy and translate these approaches to improve treatment for patients with peripheral neuropathy. The investigators hypothesize that novel heat treatment interventions that improve mitochondrial function will improve metabolic symptoms and peripheral nerve mitochondria, leading to improvements in sensory function, via heat shock protein induction. The investigators will employ immersion heat treatment to elevate heat shock protein responses that induce positive changes in peripheral nerve mitochondria. One aspect is to confirm the efficacy, safety, and potential for heat treatment to improve sensory dysfunction in human patients with prediabetes. The goal of this proposal is 1) to test the breadth of heat treatment on various forms of neuropathy, 2) identify mechanisms in which heat treatment improves mitochondrial function, and 3) test the efficacy, safety, and potential for heat treatment to improve sensory dysfunction in human patients with prediabetes.
The purpose of the study is to learn about how type of exercise influences measures of appetite regulation.
The purpose of this study is to investigate the effects of dapagliflozin therapy on myocardial perfusion reserve (MPR) using dynamic SPECT examination in prediabetic patients with stable CAD. Dapagliflozin therapy versus lifestyle modification improves myocardial perfusion reserve in prediabetic patients with stable CAD.
The purpose of this research is to study the effects of 1,25(OH)2 D3 (a prescription form of active Vitamin D) on muscle strength and insulin secretion by the pancreas and glucose utilization by skeletal muscle.
Purpose: The investigators propose a 20-participant randomized 2-arm parallel trial with a delayed-intervention control examining how 8 weeks of moderate-intensity walking exercise alters the gut microbiome, short chain fatty acid (SCFA)-producing taxa, and the cardiometabolic profile and body weight of individuals who are overweight or obese and have prediabetes (PreD). Aim 1: Examine and compare exercise-related shifts in the gut microbiome of individuals with PreD. Aim 2: Examine and compare exercise-related changes in SCFA-producing taxa. Exploratory Aim: Examine what percentage of the exercise-related changes observed in participants' gut microbiome and SCFA-producing taxa mediate changes in their cardiometabolic profile and body weight.
The purpose of the study is to determine if a 6-week exercise training program promotes exercise-induced metabolic flexibility, that is, the ability to switch fuel sources for energy, in older prediabetic adults.
The purpose of this study is to establish safety of biweekly intermittent fasting in the setting of type 2 diabetes mellitus or prediabetes under treatment with non-hypoglycemic agents (e.g. metformin).
Pre-diabetes is characterized by high plasma concentration of glucose and glycated hemoglobin and is the main risk factor for the development of type 2 diabetes. Several studies show that the intestinal microbiota is intimately linked to cardio-metabolic factors (type 2 diabetes, insulin resistance) when in situations of dysbiosis. Food is a key element for a healthy microbiota, focusing on the consumption of polyphenols that modulate the intestinal environment through its alteration and production of short chain fatty acids, and can thus be a way of reversing situations such as pre- diabetes and insulin resistance. The objective of the study will be to investigate whether chronic supplementation of eriocitrin alters the intestinal microbiota of pre-diabetic and insulin resistant individuals, reversing these situations. This will be done by supplementation of eriocitrin-containing capsules with different dosages in pre-diabetic and insulin resistant individuals. There will be 12 weeks of intervention, with faecal collections, anthropometric and dietary evaluation, and then will be made microbiological analysis to identify the intestinal microbiota and biochemical analysis before and after the intervention. For statistical analysis, normality and homogeneity test (Kolmogorov-Smirnov and Levine test respectively), T-test to compare baseline time between groups and repeated-measures ANOVA (two-way) were used to compare changes within and between groups.
