Active clinical trials for "Prediabetic State"

The purpose of the study is to determine the role of beta-cell function and insulin resistance in the development of impaired glucose tolerance (IGT) and type 2 diabetes in children and adolescents who have an increased risk of developing type 2 diabetes due to overweight/obesity or a family history of overweight/obesity, diabetes and/or impaired fasting glucose. It is hypothesized that: 1)Obese adolescents with IGT will be more insulin resistant than obese adolescents with NGT. Insulin resistance will be the best predictor of changes in glucose tolerance status., 2)Beta cell function will be impaired in obese adolescents with IGT compared to obese adolescents with NGT., 3)Obese adolescents with IGT will present with greater intramyocellular, intrahepatic and visceral fat than obese adolescents with NGT. Furthermore, obese adolescents with IGT will have larger adipocytes, while having significantly fewer adipocytes compared to obese adolescents with NGT. Obese adolescents with IGT will also have altered expression of key genes related to insulin resistance., and 4)Abnormalities in endothelial function as manifested by low FMD and PAT are already present in obese adolescents with IGT and are linked to insulin resistance.

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.

Type 2 diabetes is a common metabolic disorder arising from a complex interaction between genetic predisposition and the environment. The development of this disorder is preceded by impaired glucose tolerance and elevated fasting glucose which also carry adverse cardiovascular risk. To date a few common genetic variants have been reliably associated with predisposition to type 2 diabetes. However, it is uncertain how these genes interact to alter insulin secretion and insulin action prior to the development of type 2 diabetes. We propose to utilize an established population-based cohort to determine how common genetic variants associated with type 2 diabetes alter the response to an oral glucose challenge in people without overt type 2 diabetes. This will enable us to understand how common variants alone or in combination alter whole-body glucose physiology and predispose to type 2 diabetes.

Background: Preventing type-2 diabetes mellitus begins with early screening and intervention of prediabetic participants. Until now, prediabetes screening and early intervention have not been optimal. The rapid advancement of technology, as well as its increased use, may provide an opportunity to improve the quality and cost of healthcare services. It is quite practicable to investigate and implement a valid, practical and easy-to-use mobile health application for participants and health staffs in screening and early intervention of prediabetes participants at primary health cares setting. This protocol aimed to identify and develop a valid, practical, and easy-to-use mobile health application for screening and early intervention of prediabetes participants at primary health cares. Methods: This protocol was prepared in accordance with the Standard Protocol Items: Recommendations for Interventional Trials 2013 statement. This is a mixed-methods study with sequential exploratory approach. This project will begin with in-depth interview to gather qualitative information regarding mobile health application necessity for prediabetes participants at the primary health cares. The impact of the usage will be studied quantitatively using randomized controlled trial. Prediabetic participants and primary health cares staffs at Yogyakarta province will be the research subjects. The collected findings will be examined based on the type of the data. Discussion: The proposed research aimed to obtain information and trial results regarding mobile health application usage for prediabetes participants screening and early intervention at primary health cares setting.

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.

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.

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.

There are few longitudinal studies in the Caucasian population and even less in the Italian population in subjects with impaired glucose regulation to allow: An estimate of the rate of conversion to type 2 diabetes; To identify subjects at risk; and To assess the physiopathologic mechanisms responsible for the conversion. In order to set up a longitudinal study capable of defining the above parameters it is mandatory that the physiological, biochemical, and, genetic markers specific for IGR are identified. The goals of the present research proposal are: To clarify the physiological mechanisms responsible for IGR; To identify the biochemical and beta-cell auto-immune parameters present in IGR; Identify genetic markers. The subjects who will be identified will add up to other 900 individuals who will be recruited as part of a follow-up program sponsored by the Italian Society of Diabetes, specifically designed to assess conversion rate to diabetes.
