Diabetes Clinical Trials

Patient Power is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), other musculoskeletal conditions, chronic neurological conditions like migraine, chronic pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, autoimmune dermatological conditions such as psoriasis, and other chronic inflammatory or immune-mediated conditions. In addition, since patients with chronic conditions often have other co-morbidities like cardiovascular health and obesity-related metabolic disorders, these conditions will also be included. Participants will provide information from their smartphones or personal computers. The information will be used by researchers and clinicians to help patients and their providers make better, more informed decisions about treatment of chronic conditions. Read Less

The goal of this randomized trial is to determine the optimal combination and sequence of three enhancements for a team-based care model for patients living with diabetes in Chicago. The study aim is to determine optimization of intervention components. Participants will be randomly assigned to diabetes self-management training or remote glucose monitoring. After 6 months, participants will be rerandomized to a subsequent study arm (including a CHW support program) depending on a tailoring variable of change in A1c. Researchers will compare the final 6 study arms to see which combination and sequence of enhancements produces the most improvement in A1c. Read Less

Skeletal muscle metabolic health is critical for mobility and an underrecognized target of metabolic acidosis in chronic kidney disease. Impaired muscle mitochondrial metabolism underlies poor physical endurance increasing the risk of mobility disability. The proposed project will use precise in vivo tools to study the pathophysiology of poor physical endurance in a clinical trial treating metabolic acidosis among persons living with chronic kidney disease.

The development of type II diabetes (T2D) is strongly associated with obesity and both are well-established risk factors for cardiovascular disease. Knowing that vascular dysfunction is an early event in the development of cardiovascular disease in obese diabetic (OB-T2D) patients, The investigators set their long-term goal to define molecular mechanisms of vascular dysfunction and corrective strategies that target these mechanisms such as physical activity and weight loss. The investigators recently discovered that human adipose tissues release extracellular vesicles (adiposomes) that are efficiently captured by endothelial cells. Adiposomes are known to carry bioactive cargos such as proteins and micro RNAs; however, their lipid content has not been studied nor has their ability to transfer their lipid cargo to endothelial cells. In the current application, the investigators propose to investigate the role of adiposomes in communicating the unhealthy milieu, mainly dysregulated lipids, to endothelial cells in OB-T2D subjects. On top of these lipid species that the investigators propose to be carried by adiposomes are glycosphingolipids (GSLs). These lipids originate from the glycosylation of ceramides, a chemical process that is upregulated in the presence of inflammation and high glucose levels. Preliminary findings showed that in endothelial cells, GSL-rich adiposomes disturb plasma membrane structure and subsequently induce endothelial dysfunction. Moreover, the investigators found that preconditioning endothelial cells with high shear stress (which is an exercise mimetic) protected endothelial cells from the detrimental effects induced by adiposomes. Therefore, the central hypothesis is that adipose tissues in OB-T2D patients release GSL-loaded adiposomes that induce vascular endothelial dysfunction. The researchers propose that exercise and weight loss interventions (bariatric surgery) will restore adipose tissue homeostasis, reduce GSL-loaded adiposomes, and subsequently alleviate vascular risk in OB-T2D patients. The investigators will test the hypotheses by pursuing the following aims: aim 1: Investigate the role of GSL-rich adiposomes in the pathogenesis of endothelial dysfunction in OB-T2D adults; aim 2: Test the effectiveness of exercise training in reducing adiposome-mediated effects on vascular function; and aim 3: Examine changes in adiposome/caveolae axis following metabolic surgery and their association with vascular function.

The treatment in this trial consists of intraocular islet transplantation. A single dose of 1000 - 2000 Islet Equivalents (IEQ)/kg recipient body weight (BW) will be infused into the anterior chamber of the eye through a self-sealing incision of the peripheral cornea. The procedure is projected to take approximately 20-30 minutes. Subject will remain flat on their back for 1-3 hours after islet infusion to maximize adhesion of the islets to the iris. Read Less

The purpose of this study is to evaluate whether placing stent(s) for a blockage in a leg vein will help improve the healing of diabetic foot ulcers (DFU). The investigators know from having taken care of many patients with diabetic foot ulcers that it is a major cause of disability and amputation. These diabetic foot ulcers frequently heal slowly or not at all. They sometimes become infected and require antibiotic therapy, debridement and amputation. The investigators normally take care of a diabetic foot ulcer with a combination of local wound care, surgical debridement if necessary, antibiotics if there is an infection, and reduction of pressure on the area of the foot with the ulcer. The investigators observed that some patients with a diabetic foot ulcer also have a blockage in a major leg vein referred to as the iliac vein. This blockage in the iliac vein prevents the proper flow of blood from the leg. This blockage results in pressure within the leg veins leading to swelling in the legs which may also prevent healing of the diabetic foot ulcer. This study will investigate whether placing stent(s) to treat the blockage(s) will improve healing of the diabetic foot ulcer and reduce some of the complications associated with a diabetic foot ulcer. The results of this study could result in a new treatment that will allow future patients with diabetic foot ulcers to heal better. Right now, placing stents for these blockages in the iliac vein is not the standard of care treatment for a diabetic foot ulcer. In order for us to determine whether stent placement is helpful, the researchers will have to randomize each patient. In other words, to reduce bias, patients will be assigned either to a group receiving a stent or to a group not receiving a stent. Every patient in both groups will receive the standard of care for a diabetic foot ulcer and undergo an x-ray with contrast and intravenous ultrasound examination of the legs. The standard of care for a diabetic foot ulcer may include local wound care, antibiotic therapy, debridement and/or amputation, and pressure offloading in the foot. Read Less

The proposed study, NC Works4Health (NCW4H), builds on the strengths of long-standing academic-community research partnerships between this UNC at Chapel Hill (UNC) team of investigators and key stakeholders across health, social service, employment, and economic development sectors. The overall goal of this study is to test the effectiveness of a multilevel intervention that can be readily adopted by communities to reduce chronic disease risks in socioeconomically disadvantaged populations by (a) embedding prevention efforts in DSS-E programs at the individual level, and (b) enhancing supervisor supports for DSS-E hires at the employer level. Interventions at each level, and their joint effects, are designed to mitigate the psychological, behavioral, and clinically relevant risks for chronic disease onset, morbidity, and comorbidity that accrue with unemployment and the employment-entry transition.

This study will conduct a two-arm randomized controlled trial to test the efficacy of a culturally tailored version of the NYU Caregiver Intervention (NYUCI) plus enhanced support (ES) through online chat groups (the NYUCI plus WeChat/Kakaotalk [population social media app for Chinese/Korean] peer support which we call the NYUCI-ES in reducing health risks for cardiometabolic disease among older Chinese and Korean American adults caring for relatives with ADRD. In collaboration with community organizations across the New York and northern New Jersey metropolitan area, we will enroll 300 caregivers of people with ADRD (150 Chinese and 150 Korean) in this study. Aim 1: Develop culturally adapted informational and educational materials about dementia and caregiving issues for social service providers of the intervention and for family caregivers. Aim 2: Test the hypothesis, H1: A counseling and support intervention (the NYUCI-ES) will significantly improve psychosocial factors such as depression, stress self-rated health and chronic disease management among Chinese and Korean-American ADRD caregivers and these changes will be mediated by improvement in social support. H1a: By the first (6- month) follow-up, the mediators (increases in social support, stress reaction) will improve significantly in the intervention group compared to baseline values and the control group. H1b: These improvements will be maintained, and lead to reduction in depressive symptoms, and improvement in self-reported health and chronic disease self-management by the 12-month follow-up compared to the control group. Aim 3: Test the hypothesis, H2: the NYUCI-ES will reduce biologic risk factors, including metabolic health (glycosylated hemoglobin) and inflammation (Oxidative stress, lipid metabolism, etc.) within 6 months of enrollment compared to baseline and a control group; these changes will be mediated through increases in social support and decreases in depressive symptoms and will be maintained at the 12-month follow-up. The public health significance of these findings will likely have an impact on health care policy for CGs from diverse underserved ethnic and cultural backgrounds, potentially reducing morbidity, and improving their quality of life.
