Filter by:Participants will be randomly assigned to either regular or no-carrageenan prepared diets to determine whether the no-carrageenan leads to improvement in glucose tolerance. Hemoglobin A1c is the primary outcome measure.
The investigators performed a 8-week, randomized, double-blind, placebo-controlled crossover human trial to evaluate the efficacy and safety of persimmon leaf extract on blood glucose. The investigators measures changes in diabetes associated parameters, including fasting blood glucose, postprandial blood glucose, insulin, C-peptide and HbA1c.
Prediabetes is a term that refers to alterations in glucose homeostasis, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or both, involving a higher risk of progression type 2 diabetes mellitus (T2DM). Dapagliflozin is a selective and reversible inhibitor of sodium-glucose type 2 (SGLT-2) co-transporter, which reduces renal glucose reabsorption and promotes the glucose excretion through urine, so that the blood glucose is improved in patients with T2DM. Although this mechanism is independent of insulin, there are evidence of improved secretion and insulin sensitivity, so it is interesting to assess these effects in patients with prediabetes, as potential therapy for treating such disorders and prevent progression to T2DM. The aim of this study is to evaluate the effect of Dapagliflozin on insulin secretion and insulin sensitivity in patients with prediabetes. The investigators hypothesis is that the administration of dapagliflozin improve insulin secretion and insulin sensitivity in patients with prediabetes.
Diabetes mellitus (DM) imposes an approximate 2-fold increased risk of atherothrombosis. Patients with type 2 DM have a 2- to 4-fold increase in the risk of coronary artery disease (CAD) and atherothrombotic complications. Current evidence indicates that altered platelet function and "reactivity" are key determinants of arterial and venous thrombosis in metabolic syndromes. In addition, venous thrombosis and pulmonary embolism are associated with increased body mass index, a common feature of type 2 DM and the metabolic syndrome. Altered platelet behavior, function, and phenotype may be critical factors in these thrombotic complications as well. The mechanisms that lead to altered phenotype and function of platelets in DM, and that underlie heightened contributions of platelets to thrombotic complications in type 2 DM, are nevertheless incompletely understood. In this project, the investigators will prospectively determine if clinical intervention with metformin--a commonly-used therapeutic agent that reduces blood glucose, promotes weight loss, and improves lipid profiles--reverses platelet reprogramming and hyperreactivity in obese subjects with impaired fasting glucose and thus, at-risk for type 2 DM. In addition to metformin, all participants will be given lifestyle modification (LSM) education on diet and physical activity, followed by guidance on how to adhere to the LSM, depending on random assignment to intervention group (education only (n=26) vs. implementation intentions alone (n=27) vs. implementation intentions with partner (n=27)). The LSM coaching for different intervention groups will allow the investigators to test whether there are more effective ways for adherence than others. Participants in these three LSM intervention groups will be further randomized to either Metformin (n=40) or Placebo (n=40), such that participants in the three LSM groups will be randomly and evenly distributed across the two study medication groups.
The overall goal of this study is to investigate the effects and the mechanisms of action of a fish peptide and vitamin D on glucose metabolism, insulin secretion, and cardiometabolic risk profile in overweight men. Transcriptomic and metabolomic approaches will be used to study the acute physiological effects of fish nutrients and to discover gene/metabolite networks that underlie these effects.
The goal of this study is to evaluate an online Diabetes Prevention Program adapted for patients with prediabetes in safety net health care settings.
"The goal of this work is to critically test the hypothesis that there exists a different profile of bile acids (BAs) in patient with type 2 diabetes mellitus (T2DM) compared with normal controls. Through confirmation of different profile of BAs in T2DM, investigator will suggest modulation of specific bile acids as a new possible treatment target in patients with T2DM. Investigator also expect the specific BAs signature will be used to screen T2DM before hyperglycemia. In addition, investigator will evaluate the association between each BA species and serum total glucagon like peptide-1 (GLP-1) or fibroblast growth factor-19 (FGF-19) concentrations to determine if the specific BAs profile is related with total GLP-1 or FGF-19 concentration in serum. Investigatr also evaluates the correlation between each BA species and metabolic profiles and oxidative stress marker to find possible roles of each BA component in glucose metabolism.
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.
An adaptation to a cold environment is a tendency to generate heat within our body. Some of this heat comes from our fat tissue. Although most fat tissue is "white fat", there are pockets deep within the body that are called "brown fat", which are specially adapted to burning fat and making heat. The investigator believes that our white fat, just underneath the surface of our skin, also has this property to burn fat and make heat, although not at the high level of brown fat. This study is to examine this fat-burning property of the white fat under the skin in response to seasons and to cold. Many such studies have been done in mice, but little has been done in humans. There are a number of factors, including age, weight, and medical history, that may make a person eligible or ineligible to participate in this study. Certain medications could make a person ineligible, but if these medications can be safely altered, the individual may become eligible.
In this trial, the investigational product , the active ingredients which has been proven to reduce postprandial glucose in healthy and diabetic patients, will be tested. The primary aim of this clinical study is to evaluate the possibility of the investigational product to reduce the rise of postprandial glucose AUC level in overweight Caucasian subjects with normal to prediabetic biomarkers (IFG/HbA1C), without prompting a disproportionate rise in insulin levels.
