Filter by:The glycemic index is the ability of carbohydrates in foods to induce increases in blood glucose levels after consuming them. Based on the capacity for increasing blood glucose levels, foods can be classified as having a low, medium, or high glycemic index. This property is of interest in health and nutrition because it allows estimating the impact the food will have on postprandial glycemia, which may able better food selection in situations where adequate glycemic control is required, such as in individuals diagnosed with Diabetes Mellitus. The objective of this study is to determine the glycemic index of 9 formulations of complete oral nutrition supplements and classify them based on their glycemic response.
Our study named Integrated Continuous glucose monitoring glycemic cHAracterization during Pregnancy in comparison with oral glucose tolerance test (I-CHAP) aims to establish much needed preliminary evidence in our Asian population to show the capabilities of CGM use and its wealth of data for GDM diagnosis. This study aims to test the following aims and hypotheses in a single-armed intervention pilot trial study of pregnant women undergoing the oral glucose tolerance test: Aim 1. To characterize CGM glucose values with the 3-point blood glucose measured during the OGTT procedure. The investigators hypothesize that the CGM glucose values at single time points while fasted, and after the 75-g glucose load will be positively correlated with 3-timepoint blood glucose values captured during the OGTT. Aim 2. To correlate the CGM glucose excursions and CGM-derived metrics (glycaemic variability and glycaemic control) with maternal-fetal outcomes and treatment outcomes. The investigators hypothesize that higher AUC, glycemic variability and poorer glycaemic control will better distinguish maternal-fetal outcomes and treatment outcomes, compared to the OGTT. Aim 3. To describe the acceptability of using the Dexcom G6 CGM as a diagnostic tool instead of the OGTT. The investigators hypothesize that a higher proportion of participants will report CGM to be more acceptable than the OGTT for GDM diagnosis.
Investigating the effect of oxytocin on pancreatic endocrine functions by determining insulin and glucagon secretion within physiological ranges of plasma glucose.
The goal of this clinical trial is to clarify (i) the contribution of brain insulin action on regulation of systemic metabolism, (ii) sex-specific differences in the central regulation and (iii) the influence of the menstrual cycle in women. Therefore, participants will undergo oral glucose tolerance tests combined with a double tracer dilution technique. This approach will be compared between days with insulin delivery to the brain as nasal spray and days with placebo spray.
The goal of this observational prospective project is to study the metabolic alterations during normal and complicated pregnancies, obtaining an early detection of metabolic changes, offering new insights into future prevention and treatment strategies for both mother and offspring. Primary objectives: - measurement of maternal blood adipokine levels, during the first trimester of pregnancy, in two groups of women (high and low risk), in order to identify early markers which, in conjunction with the medical history, can identify women at increased risk of developing GDM - ultrasound measurement of adipose tissue deposits at ectopic sites, comparing low- and high-risk women, and assessing the effect of pregnancy on these deposits. - Identification, by targeted ultrasound assessment, of fetuses at increased risk of macrosomia. Secondary objectives: - Evaluation of the prevalence of GDM and its complications in a population of low- and high-risk women. - Evaluation of neonatal complications in children born to low- and high-risk mothers (need for resuscitation, hypoglycaemia, hypocalcaemia, admission to neonatal intensive care unit). The participants will be recruited during first trimester ultrasound after signing the informed consent.
This study will investigate the biological mechanisms linking sleep disruption by vibration and noise, and the development of cardiometabolic disease. In a laboratory sleep study, the investigators will play railway vibration of different levels during the night. The investigators will also measure objective sleep quality and quantity, cognitive performance across multiple domains, self-reported sleep and wellbeing outcomes, and blood samples. Blood samples will be analyzed to identify metabolic changes and indicators of diabetes risk in different nights. Identifying biomarkers that are impacted by sleep fragmentation will establish the currently unclear pathways by which railway vibration exposure at night can lead to the development of diseases in the long term, especially metabolic disorders including diabetes.
Numerous evidences suggest an important role of short-chain fatty acids, produced by the intestinal fermentation of dietary fibers by the intestinal microbiota, in the modulation of various biological functions relevant to human health. In particular, butyrate, in addition to its trophic action on enterocytes, could improve insulin sensitivity and increase GLP-1 secretion, suggesting a possible role in the modulation of glucose metabolism. However, to date, very few randomized controlled trials (RCTs) have observed a significant increase in plasma butyrate concentrations in humans after nutritional interventions with high-fiber diets or foods. Butyrate occurs naturally in some foods, such as milk and dairy products, where it is often associated with sodium, becoming sodium butyrate. Therefore, recent studies suggest the use of oral sodium butyrate supplements in order to obtain a significant increase in butyrate plasma concentrations able to exert the potential beneficial effects related to them. To date, few studies have investigated the effect of oral sodium butyrate supplementation on glucose metabolism in healthy or overweight individuals, individuals at high cardiometabolic risk, and individuals with type 2 diabetes. Therefore, the purpose of this pilot study is to evaluate the effects of oral sodium butyrate supplementation, versus placebo, on glucose tolerance and insulin sensitivity in a group of overweight/obese individuals and the mechanisms underlying these effects.
There is well documented evidence that ingesting dietary carbohydrate in large amounts tends to increase postprandial glucose. In healthy populations, this is not necessarily a problem, but continuous exposure to high levels of glucose-hyperglycemia-is a defining characteristic and risk factor for type 2 diabetes mellitus. Consuming a carbohydrate-rich food as the final food in a meal sequence has been shown to significantly reduce postprandial glucose excursions in both diabetes patients and in healthy controls. The exact mechanisms behind this phenomenon are not well understood, but one proposed course is simply that the vegetable and protein already being digested slows the rate of glucose rise. Despite the findings, little-to-no research has examined how manipulating the order of foods in a meal impacts subsequent exercise responses. In this experimental crossover study, each participant will undergo two acute feeding conditions (carbohydrate-rich foods first vs. last in a meal), which will be followed by exercise 60 minutes later. We will observe the effects of meal order on postprandial glucose, substrate/fuel utilization, and subjective perceptions at rest and during 30 minutes of exercise.
The primary aim of this study is to assess the impact of incorporating Empagliflozin, an oral sodium-glucose co-transporter 2 (SGLT2) inhibitor, into the existing therapeutic regimen of Insulin+Metformin+Dipeptidyl peptidase 4 (DPP-4) inhibitors in poorly controlled type 2 diabetes mellitus (T2DM) patients. The study seeks to evaluate its effect on achieving glycemic goals in this patient population.
The goal of this study was to perform a clinical trial to compare the impact of herbal chickpea pulao (cooked Indian-Pakistani rice dish) on improving postprandial blood glucose levels in type-2 diabetic people. The main questions it aims to answer are: - Whether Indian rennet and fenugreek seed extract can modulate blood sugar levels or not? - At what concentration the flavor, taste, and blood sugar impact were acceptable? Participants were provided with control and intervention herbal chickpea pulao for a period of 21 days and asked to provide feedback on taste, flavor, and over-acceptability, and their postprandial blood glucose levels were checked.
