Active clinical trials for "Glucose Intolerance"

The primary goal of this study is to measure the prevalence of undiagnosed pre-diabetes/diabetes among women hospitalized with acute coronary syndromes (ACS) compared to men. Inpatients with confirmed ACS (and no known prior history of diabetes) are invited to return to the Yale Hospital Research Unit 6-8 weeks after hospital discharge for an oral glucose tolerance test to identify individuals with pre-diabetes and diabetes.

The purpose of this study is to determine whether therapeutic intervention on impaired glucose tolerance in patients with coronary heart disease can decrease the incidence of new onset DM.

Background: Previous epidemiological and animal studies have suggested a strong relationship between prediabetes and Alzheimer's disease. Recently, we demonstrated that plasma β-amyloid (Aβ), a potential biomarker for Alzheimer's disease, was elevated in individuals with type 2 diabetes. However, few studies have investigated the associations of plasma Aβ40 and Aβ42 concentrations with prediabetes. Objective: we aimed to investigate the associations of plasma Aβ40 and Aβ42 concentrations with risk of prediabetes in two independent studies. Design: We performed a case-control study and a nested case-control study within a prospective cohort study. In the case-control study, we included 571 newly diagnosed individuals with prediabetes and 571 control participants. Prediabetes individuals were consecutively recruited from subjects who attended the outpatient clinics of Department of Endocrinology at Tongji Medical College Hospital from 2012 to 2015. Concomitantly, we recruited healthy controls from a general population undergoing a routine health checkup in the same hospital. One healthy control was selected at random for each prediabetes individuals according to age (±3 years) and sex. The inclusion criteria of participants were as follows: age ≥30 and ≤80 years, BMI <40 kg/m2, no history of prediabetes and diabetes mellitus, no history of receiving pharmacological treatment for hyperlipidemia, nor any clinically systemic disease, any acute illness, and chronic inflammatory or any infective disease. An independent nested case-control study was conducted within an ongoing cohort study, namely the Tongji-Ezhou cohort. Briefly, 5533 participants, including 3101 retired employees and 2432 working employees, were enrolled from Echeng Stell and received healthcare for a baseline investigation between 2013 and 2015. The first follow-up for all participants was finished by mid-2020. Considering the low incidence of prediabetes among young working employees, we performed the nested case-control study among retired employees. During the follow-up, 119 new-onset prediabetes cases were diagnosed within the retired employees according to fasting plasma glucose. We randomly selected the control participants who matched 2:1 to the cases by age (±3 years) and sex from the retired employees with normal fasting plasma glucose. The inclusion criteria were the same as the case-control study; 2 new-onset prediabetes cases aged >80 years were excluded. Additionally, 17 cases without enough plasma were excluded. Finally, 100 individuals with new-onset prediabetes and 200 well-matched control participants were included for the analysis of the nested case-control study. These two studies were approved by the Ethics and Human Subject Committee of Tongji Medical College. All enrolled participants in the two studies were of Chinese Han ethnicity and provided informed written consent. Plasma Aβ40 and Aβ42 concentrations were simultaneously measured by validated assay platforms from Meso Scale Discovery (MSD; Rockville, MD, USA).

There is evidence that gastrointestinal operations for non weight-losing purposes are beneficial for diabetes mellitus. Aiming to analyze such hypothesis, patients submitted to gastric bypass for morbid obesity, gastrectomy for gastric cancer and colectomy for colo-rectal cancer will be compared. The end point will be changes in fasting blood glucose and hemoglobin A1c concentration.

The main objective of the study is to estimate and compare the percentage of patients with abnormal glucose metabolism at 4-12 weeks postpartum between two groups: patients diagnosed with gestational diabetes before or after 24 weeks of pregnancy. Abnormal glucose metabolism is defined as type 2 diabetes, glucose intolerance or impaired fasting glucose.

The rationale for this trial is to apply a simple and minimally strenuous pre-screening approach prior to performing more extensive trial-specific screening and baseline-characterization activities in the resulting pre-selected population of subjects.

A multi-year clinical study to improve tools for measuring the function of insulin-producing beta cells in people with type 2 diabetes mellitus.

The purpose of this study is to determine if a 6-month community-based prediabetes lifestyle and behaviour change intervention (called, PREPARE) for middle and older adults with prediabetes will result in positive lifestyle behaviour change.

Hypothesis : The maximum body weight in lifetime is associated with the onset of development of type 2 diabetes.

Impaired glucose tolerance is associated with an increased risk of developing cardiovascular disease and atherosclerosis for reasons not yet totally understood. Previous studies evaluated the kinetics of plasma LDL and a faster removal rate of free cholesterol in normolipidemic patients with diagnosed arterial coronary disease and deposits of this cholesterol on the blood vessel walls. This disassociation of the cholesterol may suggest a new mechanism for not only the genesis but for the progression of arterial coronary disease. The objective of this research was to study the plasma kinetics of free cholesterol and cholesterol ester in impaired glucose tolerance patient, asymptomatic for coronary artery disease (CAD), to elucidate mechanisms involved in atherogenesis in these patients.
