Active clinical trials for "Diabetes Mellitus"

The primary aim of the current study is a better understanding of the role of Type 2 Diabetes Mellitus (T2DM) in heart failure and, in particular, changes in cardiac metabolism, which may contribute to heart failure. Various biomarkers in the coronary artery blood, as well as in the arterial and peripheral venous blood, are to be identified for this purpose. Included are patients with and without T2DM, who have a clinically indicated and guidance-appropriate Cardiac Resynchronisation Therapy (CRT) implantation due to their cardiac insufficiency. Not all patients currently benefit from the implantation of a CRT system (so-called non-responder). Despite narrow inclusion criteria, these "non-responders" cannot be unmasked in advance of the implantation. A further aim of this study is to identify biomarkers, which can be determined in advance of implantation to differentiate between responders and non-responders.

Obesity affects over one third of US adults (>72 million, with BMI ≥30 kg/m2), and the proportion of US adults with BMI ≥40 kg/m2 has doubled in the last 20 years. Obesity is associated with increased mortality through its linkage to comorbidities including diabetes, hypertension, dyslipidemia, osteoarthritis, sleep apnea and psychosocial disturbances. Given its prevalence, impact on morbidity and mortality, and economic cost, limiting the spread of obesity and its consequences is one of the most important problems of our time. In this proposed study, investigators will recruit participants from a wide range of body mass index (BMI), ethnicity and Diabetes risk to collect data and blood, stool and adipose tissue samples in the San Francisco bay area.

This study seeks to examine the impact of bariatric surgery on oral bacteria in diabetic compared to non-diabetic patients. The purpose of this research study is to examine how diabetes changes the bacteria in the mouth. This is an important question since bacterial changes may impact oral health. Participants will attend a screening and baseline visit prior to bariatric surgery and three post bariatric surgery appointments (3 weeks post, 6 months post and 1 year to 18 months post). Samples collected at each study visit include blood, plaque, and other oral samples. At the last study visit there is an optional dental cleaning.

Evaluate the impact of conducting a screening questionnaire (FINDRISC) and the implementation of a point-of-care HBA1c test for those with identified risk to suffer Diabetes in ten years, to improve the proportion of patients attending for a confirmatory test ( oral glucose tolerance test ) and evaluate the impact of such a strategy to minimize type 2 diabetes outcomes.

Type 1 diabetes (T1D) is characterized by absolute insulin deficiency. Although the discovery and application of exogenous insulin has prolonged the lifespan of T1D patients, the chronic diabetic complications caused by long-term poor glycemic control will still reduce patients' quality of life and the overall life expectancy. According to the studies focused on long-term T1D, part of the patients with long disease duration showed resistance to microvascular complications, and several protective factors have been identified. The prevalence of T1D in China is extremely low compared to that in the western world, and little is known about the characteristics of patients with long-term T1D in China. Therefore, this study is designed to collect variable clinical and laboratory features of patients with long-term T1D, explore the risk and protective factors for the development of microvascular complications, and provide reference for the prediction and prevention of these complications.

Exhaled volatile organic compounds will be measured during daytime with the goal to identifying circadian variability. The study incudes three subgroups: people without diabetes, people with type 1 diabetes, and people with type 2 diabetes. A total of 60 people will be recruited for the study.

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.

The global rise in the prevalence of obesity paved the way for the increased prevalence of yet another obesity-related complication significant enough to be considered within the roster of major public health threats: non-alcoholic fatty liver disease (NAFLD). In this follow-up study, the investigators will attempt to decipher the natural history of hepatic steatosis among patients with type 2 diabetes mellitus (T2DM) using state-of-the-art methods in a well-characterized Saudi cohort. The investigators aim also to validate existing biomarkers of disease severity and explore the pathogenesis of progressive disease using metabolic profiling technologies. A total of 1000 adult Saudi patients (males and females) with T2DM will be recruited. Those with co-morbidities, including hepatic decompensation, will be excluded. Participants will be followed three times for a total of 10 years/patient (Year 2, Year 5, and Year 10), and measures such as dietary evaluations, anthropometrics, and urine, stool, and blood examinations will be performed. Patients who develop NAFLD will be noted, and patterns/changes in the metabolic profile will be examined. For this specific grant (the first 2 years of the whole project), the investigators will be able to recruit the study cohort, do the baseline anthropometric, imaging, and biochemical measurements, and report the prevalence of NAFLD among patients with T2DM. This information will be the basis of subsequent follow-up and allow for validating potential diagnostic and prognostic biomarkers. This project will be of high importance at the national level since it will create awareness in the local medical community of the current severity status of NAFLD in the kingdom and will be used as a tool to promote public health awareness in the community.

This project is expected to screen reliable serum markers in pregnant women with gestational diabetes mellitus (GDM) by using metabolic profiling and lipid profiling clinical high-throughput mass spectrometry technology. We intend to build an early pregnancy prediction model for postpartum glucose metabolism abnormalities of GDM. At the same time, this project plans to develop a predictive management system based on this model, so that it can be widely used in clinical detection process, realize the advance of the early warning window period of abnormal glucose metabolism, and provide theoretical guidance for the early postpartum blocking of GDM to the outcome of abnormal glucose metabolism.

The goal of this observational study is to learn about the role of Time-in-Range to stratify the risk of micro vascular complications in adults with type 2 diabetes. The main questions it aims to answer are: Is a lower Time-in-Range associated with a higher risk of diabetes microvascular complications, independent of HbA1c? Is Time-in-Range lower among sulfonylurea and premixed insulin therapy users compared to non-sulfonylurea and non-premixed insulin therapy users, respectively.
