Active clinical trials for "Prediabetic State"

In a 6 week pilot study, 20 individuals with habitual sleep restriction will all be asked to extend their nightly sleep by 1 hour, and will then be randomized 1:1 to nightly controlled-release oral melatonin (2mg) or placebo. The investigators will assess whether sleep extension and nightly melatonin supplementation in the community is a feasible intervention with a beneficial effect on the following chronic kidney disease (CKD) risk factors: systemic and renal specific renin-aldosterone-angiotensin system (RAAS) activation (systemic plasma renin activity, plasma angiotensin II levels, 24-hour urine aldosterone excretion, and renal plasma flow response to captopril); nocturnal blood pressure measured by 24-hour ambulatory blood pressure monitor; central blood pressure measured by pulse wave analysis; and glucose metabolism measured by Minimal Model assessment of insulin resistance and β-cell response to a mixed meal protocol.

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.

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.

Brassicaceae plant family have a high content of bioactive compounds such as e.g. glucosinolates (GSLs) and isothiocyanates (ICTs) associated, recently, with diabetes prevention. This research proposal has the intention of evaluating if the ingestion of freeze-dried nasturtium has a positive effect on the insulin response, lipid profile, oxidative stress biomarkers and gene expression of RESISTIN, GLUT 4, acetyl-CoA carboxylase-a (ACC), fatty acid synthase (FASN), NRF-2, NQO1, SFRXN1, glutathione peroxidase 2 (GPx-2), FOXO1, FOXO3 and FOXO6 in subjects with glucose intolerance.

More than a third of the adult population in England have prediabetes, a condition that occurs when glucose levels are higher than normal but not high enough to be diagnosed as diabetes. Between 5 and 10% of people with prediabetes will go on to develop diabetes each year. Lifestyle (diet and activity) interventions have been shown to reduce the risk of prediabetes progressing to Type 2 diabetes. However, in practice high levels of professional support coupled with increasing incidence of prediabetes are not sustainable in their current format. The internet has the potential to provide an alternative means of supporting large numbers of individuals in making lifestyle changes. However, provision of information on its own is not enough to engage individuals to change - additional support via personalised feedback is required to sustain the level of motivation needed for long term behaviour change. AIM: The investigators hypothesis is that communicating with individuals at high risk of Type 2 diabetes via a web-based lifestyle app will lead to changes in lifestyle behaviours resulting in an improved glycaemic control and reduction in diabetes risk. METHOD: The study will be conducted over 6 months. Patients identified in GP practice who are at high risk of developing diabetes will be invited to take part in this feasibility study. Intervention (6 months): This will consist of a web-based lifestyle app and personalised behaviour modification advice delivered via messaging by a dietitian. Participants will also be issued with a pedometer. Data on the dietary intake and activity levels will be collected on the web-based lifestyle app. Contact between the dietitian and participants will consist of weekly messaging to facilitate changes in diet and activity behaviour through motivational and cognitive behavioural strategies. Blood biochemistry (HbA1c, FBG, LFT's and lipids), BP, weight, BMI, and waist circumference will be measured at 0, 3 and 6 months. The blood test will be taken by a practice nurse at the GP practices and sent off for analysis. A 5 day food diary, well-being and activity questionnaires will be collected at 0, 3 and 6 months by the researcher. At the end of the intervention period, participants will be invited to attend a focus group to assess participants' perceptions/ease of use and barriers to use of the technology employed to assist behaviour change

The objective of this study is to test whether two different participant financial incentive structures are more effective and cost effective than minimal financial incentives in increasing weight loss among Minnesota Medicaid beneficiaries at high risk of developing diabetes. The incentives are tied to participation and weight loss in the evidence-based group-delivered YMCA diabetes prevention program (Y-DPP). The Investigators will conduct a group randomized trial that includes up to 150 Y-DPP classes of 10-15 participants per class for up to 1500 Medicaid beneficiaries participating in the Y-DPP classes. This approach, if successful, will (a) improve weight loss. diabetes risk, and improve cardiovascular risk among Medicaid beneficiaries at risk for developing diabetes and other chronic conditions, (b) demonstrate that prevention of chronic disease risk factors using patient incentives is cost-effective, and (c) provide a patient incentive model that can be widely used among Medicaid beneficiaries at risk for developing diabetes.

The work plan will have the following S&T components. Component 1: Cross-sectional Study Cross-sectional study will be of 1.5 years where 400 women from rural will be screened randomly for the vitamin D deficiency and its determinants including duration of sun exposure. Component 2: Prospective Study This open-label randomized placebo-controlled trial would be done in 150 pre-diabetic women with vitamin D deficiency. The women will be recruited from cross-sectional study, out patient department and health camps and they will be followed up for 2 years. The women will be randomized into two groups; lifestyle modification counseling along with intervention with either vitamin D or placebo. The levels of vitamin D and blood glucose will be assessed periodically (every 6 months). In those having recurrent vitamin D deficiency, the course of vitamin D will be repeated. At the end of the study, incidence of T2DM in both groups will be compared.

Cardiovascular disease (CVD) is the leading cause of death in the United States. Short-term increases in blood sugar, or postprandial hyperglycemia (PPH), affect blood vessel function and increase the risk of CVD. Greater intakes of dairy foods have been associated with a lower risk of CVD, but whether these effects occur directly or indirectly by displacing foods in the diet that might increase CVD risk is unclear. The health benefits of dairy on heart health are at least partly attributed to its ability to limit PPH and resulting PPH-mediated responses leading to vascular dysfunction. This provides rationale to further investigate dairy as a dietary strategy to reduce PPH and risk for CVD. The objective of this study is to define the extent to which dairy milk, and its whey and casein protein fractions, protect against postprandial vascular dysfunction by reducing oxidative stress responses that limit nitric oxide bioavailability to the vascular endothelium in adults with prediabetes.

This study tests a culturally tailored lifestyle intervention designed to prevent, or delay onset of, T2DM in Mexican Americans with prediabetes. Half the participants take part in a lifestyle program that emphasizes preparing and eating healthy Mexican American foods and increasing physical activity; the other half take part in an "enhanced" usual care control group.

The purpose of the study is to evaluate the effect of a family and interdisciplinary approach on individual and family insulin resistance and insulin secretion in patients with prediabetes.
