Filter by:This is a single site blinded RCT of 920 pregnant women with singleton gestation designed to compare the Carpenter-Coustan and IADPSG criteria for diagnosing gestational diabetes. Maternal metabolic profiles and infant growth will be assessed at randomization and at one year postpartum.
The South Asian population is facing an epidemic of type 2 diabetes, of which the underlying cause is still unknown. It is currently hypothesized that an ethnic susceptibility towards a disturbed energy metabolism may underlie this disadvantageous metabolic phenotype. In line with this, the investigators recently discovered that Dutch South Asian subjects have 32% lower resting energy expenditure (REE) and 34% lower energy-combusting brown adipose tissue (BAT) compared to matched white Caucasians. Nitric oxide (NO) was recently shown to be crucial for BAT development and, interestingly, South Asians have diminished NO bioavailability. Thus, the disadvantageous metabolic phenotype in South Asians may be caused by diminished NO bioavailability resulting in lower BAT volume. Therefore, the investigators hypothesize that increasing NO generation in the body by administration of L-arginine, the precursor of NO, will improve their metabolic phenotype by increasing BAT volume, thereby increasing REE and clearance of triglycerides and glucose by BAT. To investigate this, the investigators will perform a randomized placebo-controlled multicenter cross-over study in moderately obese Dutch South Asians and matched white Caucasians. Subjects will receive L-arginine (9 gram/day) or placebo for 6 weeks, followed by a wash-out period of 4 weeks and then again 6 weeks of one of either treatments. At the end of both treatment periods, a cold-induced PET-CT scan will be performed. Furthermore, muscle and fat biopsies will be obtained and thermoregulation will be assessed.
The purpose of open-label study is to evaluate the efficacy and safety of AO-128 (Voglibose) 0.6 mg/day in patients with impaired glucose tolerance (IGT) who had been non-responsive to diet therapy and exercise therapy, and follow up the progress after the end of treatment in patients who was assessed as normoglycemic.
In this double-blind, placebo-controlled study, subjects with prediabetes and type 2 diabetes were randomly assigned to the placebo control group or the test (Arginyl-fructose: AF) group. We determined fasting serum levels of glucose, hemoglobin A1c (HbA1c), insulin, and free fatty acids (FFAs), were measured by 2-h oral glucose tolerance tests (OGTTs) at baseline and after the 6-week intervention.
Filipino Americans (FA) are the second largest (3.4 million) Asian group in the US. and have one of the highest prevalences of obesity and type 2 diabetes mellitus compared to non-Hispanic whites, African Americans and Hispanics. However, FA have been underrepresented in health related research, particularly in diabetes prevention. This proposed pilot study is the first clinical trial to assess preliminary estimates of the short-term effect of the novel social networking diabetes prevention program lifestyle intervention for this high-risk population.
Diabetes is a major cause of morbidity and mortality worldwide. Prevention of diabetes is an important goal. The progression from impaired glucose tolerance to diabetes is thought to be promoted by the toxic effects of hyperglycemia on pancreatic beta cells. One of the main defects causing postprandial hyperglycemia in individuals with impaired glucose tolerance is reduced first phase (immediate) insulin release. The investigators hypothesis is that consuming a nutritional preload--a low-calorie, nutritionally balanced snack--30 minutes before ingesting a carbohydrate load, will moderate the hyperglycemic response to subsequent carbohydrate challenge and reduce glucotoxicity by stimulating insulin release and synthesis. The aim of this study is to test this hypothesis by comparing the standard 75-gram, two-hour oral glucose tolerance test (OGTT) response of 30 fasting adults who have impaired glucose tolerance to their OGTT response when the test is preceded by ½ ounce (14 grams) of dry-roasted, unsalted almonds. A pre-load interval of 30 minutes was chosen so that the peak of phase 2 (delayed) insulin response to the pre-load (45-60 minutes) would coincide with the timeframe of the steepest OGTT rise in glucose (15 to 30 minutes post challenge). The investigators hypothesize that the one-hour OGTT glucose level will be approximately 40 mg/dl lower when participants consume the pre-OGTT almond snack, compared to their one-hour glucose level on the standard two-hour OGTT. The two-hour OGTT glucose level is unlikely to show a statistically significant difference between the almond pre-test snack and control standard OGTT conditions.
The objective is to identify the lowest effective dose of Grape Seed Extract (GSE) on glucose control in people with impaired glucose tolerance (IGT).
This study investigated any potential associations between two isocaloric diets with different meal frequency (3 meals versus 6 meals) and glycemic control in people at high diabetes risk (lean and overweight/obese women with PCOS, individuals with hyperinsulinemia, individuals with impaired glucose tolerance) and diagnosed with diabetes.
In this study, consecutive patients with cryptogenic cirrhosis (NASH-related cirrhosis), coming to ILBS (Institute of Liver & Biliary Sciences) OPD (Out patient Department) or getting admitted in the ward will be enrolled on fulfillment of inclusion/exclusion criteria and consent of the patient. These patients will be randomised to either metformin arm or conventional treatment arm. After enrollment these subjects will be monitored every three monthly for total of 12 months or till the primary endpoint is achieved. At the end of the study, outcome will be measured appropriately.
Hypothesis 1. Prediabetes patients who have insufficient sleep will have worse glucose tolerance than those with normal sleep duration. 2. Prediabetes patients with short sleep will have a delayed or reduced GLP-1 response to a standardized meal
