Filter by:The reasons for the epidemics of diabetes and prediabetes, and why individuals from certain populations suffer at higher rates are not well known. In the Pathobiology and Reversibility of Prediabetes in a Biracial Cohort (PROP-ABC) study, nearly 400 African Americans and Caucasians whose parents have type 2 diabetes will undergo repeated testing to determine what factors lead to the occurrence of prediabetes, and whether race still plays a major role in a setting where everyone being studied has one or both parents with diabetes. The PROP-ABC Study also will test the hypothesis that the ability of intensive lifestyle intervention to reverse prediabetes and return people's metabolism back to normal is dependent on how long people have had prediabetes.
The purpose of the present study is to evaluate the effect of blueberry dry powder on glycemic status (fasting plasma glucose, 2h glucose concentration after the oral glucose tolerance test (OGTT), or HbA1c) in subjects with prediabetes.
Pregnancy-associated diabetes, known as gestational diabetes mellitus (GDM), is associated with an increased lifetime risk of developing diabetes mellitus (DM) or pre-diabetes. Up to 30% of women with GDM will continue have abnormal blood glucose tests 6 or more weeks after delivery. Early diagnosis and treatment of continued impaired glucose metabolism or DM is essential because serious health problems can result. Current guidelines recommend a 75-gram, 2-hour glucose tolerance test (GTT) 6 or more weeks after delivery for women diagnosed with GDM in order to identify those with continued DM or impaired glucose metabolism. However, approximately half of these women do not get glucose testing after delivery. The ability to test women while they are still hospitalized after having a baby could greatly increase diagnosis, care and treatment of women with abnormal glucose metabolism. Our objective is to determine if a 75-gram, 2-hour GTT administered to women with GDM two to four days after delivery can identify those who will have an abnormal GTT at 6-12 weeks after delivery.
The incidence of type 2 diabetes mellitus (T2DM) is increasing rapidly. The combination of T2DM and smoking is particularly lethal, as smokers with T2DM are significantly more likely to develop a number of health related complications. Community-based diabetes education programs (DEPs) have been developed to support patient self-care behaviours (e.g. adherence to oral medications, insulin therapy, nutrition management, regular blood glucose monitoring, and physical activity); however, specific assistance for smoking cessation is rarely provided. Our investigative team has developed a knowledge transfer and practice change process to introduce evidence-based interventions for smoking cessation into clinical practice settings. This process is known as the Ottawa Model for Smoking Cessation (OMSC). Investigators believe there is an opportunity to use the OMSC intervention to dramatically enhance the effectiveness of DEPs in addressing smoking cessation among smokers with T2DM, and in so doing, improve quit rates in this high risk population. The purpose of this project is to evaluate the effectiveness of the Ottawa Model for Smoking Cessation (OMSC) intervention in multiple diabetes education programs (DEPs) in Ontario. A two-level recruitment strategy will be employed. Eighteen DEPs will be recruited, and then a consecutive sample of eligible smoker-patients will be recruited from each DEP over a 6-month recruitment period. Investigators want to test the impact of the OMSC intervention on quit rates among smokers with diabetes and pre-diabetes referred to these programs. Investigators will conduct a matched-pair cluster design trial at 18 DEPs in Ontario. These sites will be matched based on number of annual referrals for diabetes education (≤ 500/year or > 500/year). Within each pair, sites will be allocated randomly to either OMSC intervention or control group. Following randomization, the OMSC program will be implemented at the intervention sites over a 6-month period. Following the implementation period, a consecutive sample of smokers will be recruited from both OMSC intervention and control DEPs over a 6-month recruitment period. It is estimated that this will yield a sample of approximately 445 smokers in each of the OMSC intervention and control groups. The primary outcome will be the biochemically-validated 7-day point prevalence abstinence rate six months after an index visit to the DEP. Secondary outcomes will include: rates of identification and intervention of smokers, and diabetes educators' attitudes, confidence, and perceptions of barriers and facilitators to implementing smoking cessation support as part of routine care. If proven effective, the OMSC is appropriate for implementation in DEPs across Canada and could have profound impacts on patient and community health.
The purpose of this study is to determine whether Rubus occidentalis extract could improve fasting or postprandial serum glucose levels, and related metabolic markers among patients with prediabetes (impaired fasting glucose and/or impaired glucose tolerance).
This study is being done to understand metformin's mechanisms of action regarding glucose production, protein metabolism, and mitochondrial function.
Glucose-dependent insulinotropic polypeptide (GIP) is a hormone produced in the intestine. It is released immediately after meal ingestion and increases insulin release. This, in turn, helps reduce blood glucose levels. This circuit does not work properly in humans with type 2 diabetes mellitus (T2DM). We have previously shown that a peptide called xenin-25 can amplify the effects of GIP on insulin secretion in humans. However, xenin-25 no longer does this when humans develop T2DM. Thus, it is important to understand how xenin-25 works in humans without T2DM so we know why it does not work in humans with T2DM. Acetylcholine is molecule produced by specific types of nerves. The effects of acetylcholine can be blocked by a drug called atropine. We have previously shown in mice that atropine prevents the ability of xenin-25 to increase the effects of GIP on insulin release. The purpose of this clinical trial is to determine if atropine also blocks the effects of xenin-25 in humans without T2DM. If it does, then impaired acetylcholine signaling may be one of the reasons humans develop T2DM and it could be possible to develop drugs that bypass this defect and increase insulin release in humans with T2DM.
The purpose of this prospective randomized multicenter intervention study is to determine whether in the prevention of Diabetes an intensified lifestyle intervention is superior to a conventional lifestyle intervention in high risk non-Responder subjects. Further, the intensive phenotyping to determine subgroups with an increased risk for diabetes enables an individualized prevention and therapy of type 2 diabetes mellitus.
This study aims to determine whether the use of a supplement called xylooligosaccharide (XOS) increases the number of good bacteria that live in human intestines and can maintain healthy blood sugar levels, and whether XOS has any unpleasant or unexpected side effects when consumed at different dosages. Subjects who participate in this study will be randomized to receive an eight week supply of either a lower dose of XOS or placebo (no active substance). This will be determined randomly, in a process similar to flipping a coin. Blood samples will be taken at each visits, including an oral glucose tolerance test. Subjects will also be asked to collect and bring in stool samples at three different time points during the study. Subjects will have a 50/50 chance of being assigned to the either study group. This is a double-blind study which means neither the study investigator nor the subject will know to which group he/she has been assigned. In case of an emergency, the study doctor can get this information.
The goal of the Vitamin D and type 2 diabetes (D2d) study is to determine if vitamin D supplementation works to delay the onset of type 2 diabetes in people at risk for the disease and to gain a better understand how vitamin D affects glucose (sugar) metabolism.
