Clinical Study to Assess the Long-term Effect of Pep2Dia® on Glucose Homeostasis in Prediabetic...
Prediabetic StateThe goal is to assess the long-term effect of Pep2Dia® compared to placebo intake on blood glucose homeostasis. Respective improvements will be assessed by changes in glycated haemoglobin (HbA1c) before and after the 12-weeks intervention.
A Low-Carbohydrate Diabetes Prevention Program
PreDiabetesThe investigators will conduct a single-arm mixed methods pilot study to estimate weight loss as well as the percentage of participants who achieve 5% weight loss in a 16-week, Low-Carbohydrate Diabetes Prevention Program (LC-DPP). Weight loss from the pilot LC-DPP cohort will be compared to weight loss outcomes from previously published DPP studies. The investigators will also evaluate secondary outcomes including change in physical activity, mental health, psychosocial functioning, and hemoglobin A1c over the 6-month study period.
Gelesis Glycemic Index Study
ObesityDiabetes1 moreA study to determine glucose and insulin responses to 50g and 100 g of carbohydrate with and without Gelesis200.
Development of Pre-pregnancy Intervention to Reduce the Risk of Diabetes and Prediabetes
DiabetesDiabetes Mellitus1 moreThis study is conducted in Asia. The aim of this study is to assess the efficacy of a pre-pregnancy life style intervention to reduce the risk of diabetes and prediabetes.
Piedmont Aging, Cognition & Exercise Study-2
Mild Cognitive ImpairmentPrediabetesThe purpose of this research study is to examine the effects of high and low intensity exercise for those with mild memory loss and pre-diabetes. The investigators will also examine the effects of this exercise on certain proteins and hormones in body fluids, and on brain structure and function using magnetic resonance imaging (MRI). Recent studies indicate that exercise improves memory and thinking abilities for adults with mild memory loss OR pre-diabetes. This study examines the effects of exercise on people with mild memory loss AND pre-diabetes.
Prebiotics, Gut Microbiota, and Cardiometabolic Health
PrediabetesForty-eight prediabetic men and women (50-75 years of age) will participate in a 6-week feeding study in which they will randomized to receive either 10 g/day of inulin or placebo. All subjects will be fed an isocaloric diet (50% carbohydrate, 35% fat, 15% protein,) controlled for micronutrient content for 6 weeks to avoid the potential confound of individual differences in diet on gut microbiota. Measurements of intestinal permeability, insulin sensitivity, and skeletal muscle metabolic flexibility will be made prior to and following the controlled feeding period. Stool samples will be collected to assess gut microbial communities.
The Usefulness of Postprandial Triglyceride for Assessment of Cardiovascular Risk
DiabetesPrediabetesThe hypertriglyceridemia at fasting status has been known to be an important risk factor for cardiovascular disease (CVD). Recently, postprandial triglyceride (TG) levels draw an attention as a superior predictor of CVD because of non-fasting state for more than 12 hours and importance of triglyceride-rich lipoprotein. We aim to investigate the relationship of postprandial triglyceride after fat tolerance test and intima-medial thickness and to suggest normal reference of postprandial triglyceride after fat tolerance test. In addition, we evaluate the correlation of postprandial triglyceride and incretin secretion after fat tolerance test Ultimately, we want to estimate clinical importance of postprandial triglyceride in assessment of cardiovascular risk.
Resveratrol and First-degree Relatives of Type 2 Diabetic Patients
Pre-diabetesThe main objective of the study is to investigate if resveratrol supplementation can improve overall and muscle-specific insulin sensitivity in first-degree relatives of type 2 diabetic patients. As a secondary objective the investigators want to investigate whether the improved insulin sensitivity can be attributed to improved muscle mitochondrial oxidative capacity and a reduced intrahepatic and cardiac lipid content. Furthermore, in a subset of the participants the investigators want to investigate the effect of resveratrol on glucose uptake in brown adipose tissue.
The Effect of Real Time Continuous Glucose Monitoring in Subjects With Pre-diabetes
Pre-diabetesImpaired Glucose ToleranceThis study will investigate whether real-time continuous glucose monitoring can be used as a tool for behavior change in people with pre-diabetes.
ForgIng New Paths to Prevent DIabeTes (FINDIT)
PrediabetesThis study will evaluate the effects of screening for type 2 diabetes mellitus (T2DM) and brief counseling about screening test results on weight and key health behaviors among Veterans with risk factors for T2DM. Study participants will be randomly assigned to one of two study groups: (1) Blood Test Group or (2) Brochure Group. Participants in the Blood Test Group will complete a blood test called hemoglobin A1c (HbA1c) which measures average blood sugar levels. Participants will receive brief counseling about the results from their primary care provider or someone authorized to speak on their behalf. Participants randomly selected for the Brochure Group will review a handout from the VA National Center for Health Promotion and Disease Prevention (NCP) on recommended screening tests and immunizations. All participants will be asked to complete a survey prior to study group assignment, immediately after a Primary Care appointment, 3 months after enrollment, and 12 months after enrollment.
