Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes.

The purpose of this study is to develop and test an 8-week sedentary behavior reduction intervention ("Sit Less" program) for patients with type 2 diabetes. The program aims to reduce and break sitting times among this population using an objective activity monitor and mHealth. The investigators will test the program to help diabetes patients break up sitting time, reduce daily sitting time, and move more. The investigators will also study preliminary effects of the SB reduction intervention on light physical activity, cardiometabolic markers and patient-centered outcomes, and whether diabetes patients like the program and can follow it.

This clinical research studies the physiology and immunology of new-onset post-transplant diabetes mellitus in patients undergoing allogeneic stem cell transplantation. Oral glucose tolerance tests (OGTT), hyperglycemic clamps, and immune assays will be used to define the mechanisms associated with abnormal glucose homeostasis following stem cell transplantation. Information from this clinical trial could be used to develop standardized screening procedures or to develop optimal treatment strategies for patients developing post-transplant diabetes mellitus.

PRECIDENTD is a randomized, open label, pragmatic clinical trial designed to compare rates of the total number of cardiovascular, kidney, and death events among three alternative treatments for patients with type 2 diabetes (T2D) and either established atherosclerotic cardiovascular disease (ASCVD) or at high risk for ASCVD. To accomplish this objective, we will randomly assign 9,000 patients with established T2D and ASCVD or high-risk for ASCVD in a 1:1:1 allocation to SGLT2i, GLP-1RA, or the combination. Participants will be followed for the occurrence of the trial primary endpoint of the total (first and recurrent) number of episodes of myocardial infarction (MI), stroke, arterial revascularization, hospitalization for heart failure, development of end-stage kidney disease, kidney transplantation, and mortality, counting all events from randomization until end of study.

Metabolic surgery is an emerging option to treat obesity-related metabolic diseases (e.g., type 2 diabetes) and prevent cardiovascular disease (CVD). Metabolic surgery can profoundly alter the gut microbiota; meanwhile, gut microbiota may affect surgical outcomes. Longitudinal studies that examined pre- to post-surgery changes in gut microbiota and its relation to cardiometabolic health after surgery are limited. Furthermore, few studies have included African Americans, a population with high rates of cardiometabolic diseases. The investigators aim to fill these research gaps by establishing a longitudinal, observational study of metabolic surgery patients and applying multi-omics to identify stool, blood, and/or tissue microbial features related to post-surgery cardiometabolic outcomes. In the current study, the investigators plan to enroll up to 300 patients who undergo metabolic surgery at Vanderbilt University Medical Center and follow them for up to 10 years after surgery. Fasting blood and stool samples will be collected at pre-surgery and 3-month, 1-year, 2-year, and 3-year post-surgery clinical visits. Tissue samples (e.g., biopsies of the liver and adipose and remnants of the stomach) will be collected during operation. Meanwhile, participants will complete a REDCap survey at baseline and 1-year, 2-year, and 3-year post-surgery. Participants' electronic medical records will be used to obtain additional information and facilitate long-term follow-up. The investigators will evaluate pre- to post-surgery changes in the fecal microbiome and fecal and blood levels of metabolites and proteins and the associations of microbiome, metabolites, and proteins with cardiometabolic improvements after surgery. This study will advance our understanding of the role of gut microbiota in metabolic surgery, which may translate into novel approaches to identify and treat obese patients for better cardiometabolic health.
