Filter by:The RISE Adult Medication Study is a 4-arm, 3-center, clinical trial of adults with prediabetes and early type 2 diabetes to address the hypothesis that aggressive glucose lowering will lead to recovery of beta-cell function that will be sustained after withdrawal of treatment. Adult participants (ages 20-65) will be randomized to one of the following treatment regimens: (1) blinded placebo, (2) blinded metformin alone, (3) early intensive insulin treatment with basal insulin glargine followed by open-label metformin, (4) the glucagon-like peptide-1 receptor agonist (GLP-1RA) liraglutide plus open-label metformin. The primary clinical question RISE will address is: Are improvements in ß-cell function following 12 months of active treatment maintained for 3 months following the withdrawal of therapy? Secondary outcomes will assess durability of glucose tolerance following withdrawal of therapy, and whether biomarkers obtained in the fasting state predict parameters of ß-cell function, insulin sensitivity and glucose tolerance and the response to an intervention.
Pre-diabetes, a condition characterized by hyperglycaemia, is associated with increased cardiovascular risk and reduced life expectancy, as compared to the general population. AMP-activated protein kinase (AMPK) is an enzyme that plays a key role in cellular energy homeostasis and metabolism, and recently it has been demonstrated that AMPK regulates aging pathways, as well. AMPK is susceptible to modulation through pharmacologic (e.g. metformin) and non-pharmacologic (e.g. physical exercise) interventions. This clinical trial aims to describe the effects of the AMPK pathway on longevity genes and inflammation in the setting of pre-diabetes in vivo and in vitro. To this end, the investigators will compare treatment with metformin (500 mg t.i.d) for 2 months, versus placebo in pre-diabetic subjects. The investigators will assess expression of longevity genes SIRT1, p66Shc, p53 and mTOR in peripheral blood mononuclear cells (PBMCs) ex vivo. The investigators will evaluate monocyte polarization by flow cytometry, according to the expression of surface antigens (CD68, CCR2, CD163, CD206, CX3CR1) to determine the prevalence of pro- or anti-inflammatory cells. Inflammatory cytokines (TNF-alpha, MCP-1, IL-1, IL-6, IL-10, CCL12) will also be determined. In the in vitro study the investigators will evaluate the effects of AMPK activation or inhibition on longevity gene and protein expression.
Weight loss achieved through gastric banding will be superior to treatment with metformin in preserving or restoring pancreatic beta cell function in people with prediabetes or mild type 2 diabetes.
The purpose of this study is to determine the effect of a slowly digesting starch on gut bacteria, sugar and fat metabolism, hunger hormones, and body fat in people with pre-diabetes.
This project is a clinical intervention trial that will determine the role of a functional food, flaxseed, on the control of blood glucose levels in people with pre-diabetes. People with pre-diabetes have high blood glucose levels since their cells do not respond to insulin as they should. Over time, people with pre-diabetes may progress to type 2 diabetes and have increased risk for heart and kidney diseases. Although the long-term complications associated with type 2 diabetes are well-recognized, clinicians and researchers are now realizing that some long-term damage to the body, especially the heart and circulatory system, may already be occurring during pre-diabetes. Consequently, clinicians are recognizing that glucose control, through diet, exercise and, if necessary, medications, is as important for people with pre-diabetes as it is for people with type 2 diabetes. Standard treatments for pre-diabetes are glucose control through diet, exercise, and drugs. A possible treatment that could be added to the standard treatments is intake of flaxseed. Few studies have looked at the effect of flaxseed intake on glucose control and those that have enrolled people with type 2 diabetes. To date, no studies have reported flaxseed's affect on controlling blood glucose in people with pre-diabetes. Therefore, more research is needed to determine if flaxseed is an effective means of controlling glucose levels in people with pre-diabetes. This study will help determine whether or not eating modest amounts of flaxseed every day will improve blood glucose and insulin levels in overweight or obese men and postmenopausal women with pre-diabetes. It will also show if flaxseed intake will reduce the degree of inflammation they are experiencing. If flaxseed consumption does help control blood glucose levels in people with pre-diabetes and reduce the degree of inflammation they are experiencing, it may help prevent or delay their progression to type 2 diabetes.
The purpose of this study is to evaluate the impact of a worksite lifestyle intervention for diabetes prevention among employees with prediabetes.
Objective of this study is to determine the safety and efficacy of administration of herbal supplements (Salacia leaf extract, Salacia root extract and Sesame seed extract) for 6 weeks in the management of prediabetes and mild to moderate hyperlipidemia.
The objective of IMPACT (Investigation of Motivational Interviewing and Prevention Consults to Achieve Cardiovascular Targets) is to determine the best management strategy for patients undergoing cardiovascular intervention. IMPACT is a prospective randomized trial that will enroll 400 patients post-cardiovascular intervention. The study will compare different cardiovascular prevention strategies: (1) usual care, (2) cardiovascular prevention consult, and (3) cardiovascular prevention consult with a behavioral intervention program over a 6-month period. The trial hypothesis is that for patients undergoing a cardiovascular intervention, a prevention consult and behavioral intervention is superior to usual care in reducing cardiovascular risk. The primary endpoint will be non-HDL cholesterol. Secondary endpoints include other lipid values, metabolic risk, smoking cessation, physical activity, nutritional status, medication adherence and quality of life. IMPACT is scheduled to begin enrollment in the June of 2012.
To examine whether a lifestyle program results in weight loss and thereby delays or prevents progression of pre-diabetes to diabetes, we propose a pilot randomized controlled trial of 6 weeks duration with 30 participants held at Stephanie Tubbs Jones Health Center. Participants are randomized to receive all of the following: nutrition education, exercise instruction, stress management instruction, and culinary education or follow usual care. Outcomes include: blood sugars and cholesterol, weight, waist circumference, blood pressure, diet, physical activity, perceived stress, and class attendance. Analysis is by Intention to treat analysis of variance. Results will be used to help design larger randomized trial in the future.
Tree nuts (almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios and walnuts) are an important source of unsaturated fatty acids, vegetable protein, and fibre, as well as minerals, vitamins, and phytonutrients. Although heart disease risk reduction claims for nuts have been permitted in the U.S. and general dietary guidelines and recommendations from heart associations recommend the consumption of nuts for heart protection, diabetes associations have not addressed nuts in their most recent recommendations. This omission is despite heart disease being a major cause of death in diabetes. There remains insufficient information on the usefulness of these foods in diabetes. To improve evidence-based guidance for tree nut recommendations, the investigators propose to conduct a systematic review of the effect of tree nuts on diabetes control and features of the metabolic syndrome. The systematic review process allows the combining of the results from many small studies in order to arrive at a pooled estimate, similar to a weighted average, of the true effect. The investigators will be able to explore whether eating tree nuts has different effects between men and women, in different age groups and background disease states, and whether or not the effect of tree nuts depends on the dose and background diet. The findings of this proposed knowledge synthesis will help improve the health of Canadians through informing diabetes association recommendations and heart association recommendations where they relate to diabetes.
