Diabetes Clinical Trials in Nashville, TN

CHRONICLE is a randomized trial assessing the comparative effectiveness of providing written visit information via the patient portal (NOTES) versus NOTES plus visit audio recording (AUDIO) to older adult patients with chronic diseases on quality of life and other outcomes. During the trial, the team will also invite caregivers identified by patients to join the project. Read Less

This study aims to improve patient awareness of the utility of continuous glucose monitoring systems in blood glucose monitoring and to improve patient satisfaction regarding diabetes care, particularly in the matter of blood glucose monitoring, at the transitions of care from the inpatient setting to the ambulatory setting.

A two-arm randomized controlled trial design will be used. Participants will include 291 African American women with type 2 diabetes that are at risk for development and/or progression of diabetes complications. Both arms, diabetes medical nutrition therapy (MNT) and diabetes MNT plus motivational interviewing (MI), will include: 1) a 3-month active intervention period of six biweekly (every other week), group-based, trained nutritionist-facilitated sessions; 2) a 3-month maintenance intervention period, which will include one group-based maintenance support session; and 3) a 6-month inactive period (no contact). The differences between arms is the integration of culturally-adapted MI exercises during the diabetes MNT plus MI active and maintenance intervention periods. Read Less

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.

The goal of this work is to conduct a randomized trial evaluating the effects of a behavioral intervention to increase sleep duration and quality for adolescents with type 1 diabetes (T1D). The impact of the sleep-promoting intervention on executive function and glycemic outcomes will be assessed. We will also explore multiple components of the recently identified central nervous system glymphatic system and evaluate how these components change and impact brain integrity and function with improved sleep.

PRECIDENTD is a randomized, open label, pragmatic clinical trial designed to compare rates of the total number of cardiovascular, kidney, and death events among two 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 6,000 patients with established T2D and ASCVD or high-risk for ASCVD in a 1:1 allocation to sodium-glucose cotransporter-2 inhibitor (SGLT2i) or glucagon-like peptide-1 receptor agonists (GLP-1RA). 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.

RADIANT is a network of 14 clinical sites and several laboratories dedicated to the study of atypical diabetes. The objective of this study is to define new forms of diabetes and the unique mechanisms underlying these forms of atypical diabetes. The specific aims are to: 1. Identify and enroll individuals and families with undiagnosed rare and atypical forms of diabetes. 2. Determine the etiologic basis of the metabolic disorder among individuals and families with novel forms of rare and atypical diabetes. 3. Understand the pathophysiology of individuals and families with novel forms of rare and atypical forms of diabetes. Read Less
