NCT ID: NCT05989867 Recruiting - Diabetes Mellitus Clinical Trials

Evaluation of OGTT in Patients With Post-pancreatitis Diabetes Mellitus for Diagnosis and Characterization

Start date: March 1, 2023
Phase:
Study type: Observational

To evaluate the islet function and insulin secretion pattern of post-pancreatitis diabetes mellitus by oral glucose tolerance testing, and to explore the pathophysiological characteristics of PPDM-C which provide evidence for the diagnosis of PPDM-C.

NCT ID: NCT04144595 Completed - Low Birth Weight Clinical Trials

Association Between Low Plasma Glucose After Oral Glucose Tolerance Test in Pregnancy With Impaired Fetal Growth

Start date: January 1, 2019
Phase:
Study type: Observational

Objective: To study the association of low maternal plasma glucose in 2 hour 75 g oral glucose tolerance test (OGTT) in women with impaired birth weight and determinate if this result is predictive of low birth weight (<10th percentile according to the INTERGROWTH-21st newborn weight standards for gestational age/sex). Materials and methods: OGTT at 24-34 week gestation will be performed in pregnant women, the birth weight will be compared between women with low fasting plasma glucose (FPG) (<10th percentile, <65 mg/dL) and normal FPG (≥10th percentile, ≥ 65 mg/dL) also for 1 and 2-hour plasma glucose (1-h PG/2-h PG). Receiver operating characteristic curve analysis will be used to determine the optimal lower OGTT threshold for the prediction of low birth weight.

NCT ID: NCT03506581 Completed - Insulin Resistance Clinical Trials

Dysfunctional Adiposity and Glucose Impairment

DICAMANO
Start date: January 29, 2009
Phase:
Study type: Observational

This is a large and comprehensively phenotyped cohort with fasting glycaemia where the predictive value of body composition and anthropometric measures of total and central fat distribution for postprandial carbohydrate intolerance are studied.

NCT ID: NCT03276949 Completed - Clinical trials for Oral Glucose Tolerance Test

Non-invasive Glucose Measurement Using Laser Technology

(Raman)
Start date: April 22, 2016
Phase: N/A
Study type: Observational

This study is to evaluate the capability of Raman spectroscopy as a non-invasive method for monitoring concentrations of glucose by illuminating a small spot on the skin, collecting and analyzing the return light. The glucose measurements obtained by Raman Spectroscopy are correlated with those obtained using YSI glucose analyzer and ACCUCHECK instruments.

NCT ID: NCT02894112 Completed - Clinical trials for Oral Glucose Tolerance Test

Effects of Fluid Milk in Attenuating Hyperglycemia and Hypertriglyceridemia After Meal

Start date: April 2013
Phase: N/A
Study type: Interventional

Epidemiological studies indicate that risk of type 2 diabetes is lower when milk is consumed in the regular diet. Milk products are unique in that they produce high insulin response despite their low glycemic index. The general aim of the proposed study is to determine the effect of fluid milk on attenuating the postprandial surge in plasma glucose and triglyceride after meals and its associated physiological mechanisms. The investigators hypothesize that the consumption of one or two servings of non-fat milk added to a standard oral glucose tolerance test (OGTT) solution or the high fat tolerance test meal will attenuate postprandial hyperglycemia and triglyceridemia. The investigators hypothesize that the postulated improvement in postprandial metabolic response due to the consumption of fluid milk will be associated with increased postprandial insulin secretion as well as insulin-mediated endothelial vasodilation and whole-limb perfusion.
