Active clinical trials for "Diabetes Mellitus"

The purpose of this study is to test the Share plus intervention aimed at improving the use of data sharing between people with diabetes and their care partners in order to maximize the benefits of continuous glucose monitoring. Hypothesis: Compared to the control group, persons with diabetes enrolled in the Share plus intervention group will experience clinically significant improvements in time-in-range (TIR) (>5%) at 12- and 24-weeks into the study, and improvement on diabetes distress. Care partners enrolled in the Share plus intervention group will experience lower diabetes distress at 12- and 24-weeks into the study.

The proposed research and training will allow Dr. Alana Biggers to obtain critical research skills and study a mindfulness meditation program designed to improve sleep and reduce stress in African-American adults with diabetes. If effective, this program may reduce the risk of cardiovascular disease among African-Americans with type 2 diabetes who are at high risk of cardiovascular disease.

This study proposes to examine the impact of time of day (morning versus afternoon) on the variability of blood glucose responses to high resistance exercise in a single group of patients with type 1 diabetes. Participants will be asked to wear a continuous glucose monitor during the 3 weeks of testing. During the six exercise sessions (three in the morning while fasted and three in the afternoon), participants will complete the same resistance exercise protocol.

Diabetes in the American Indian and Alaska Native (AIAN) population is a public health crisis that is best addressed using a holistic approach. Given the disproportionate rates of diabetes and diabetes-related outcomes among AIANs, this is the perfect opportunity to provide a culturally tailored health promotion intervention among the largest urban AIAN population in the U.S.; approximately 171,163 AIANs reside in Los Angeles County. It is imperative to develop culturally tailored interventions with a community-based participatory research approach. Particularly given a legacy of historical mistrust, development of trusted and mutually beneficial partnerships is imperative. The goal of this pilot study is to reach up to 312 Native Americans with diabetes to participate in an intervention to lower blood sugar and feelings of social isolation. The intervention will include 12 weeks of diabetes-friendly, medically tailored meals, and four weeks of virtual diabetes wellness classes. Participants will also attend an initial meet-and-greet before the classes start, a check-in meeting after the classes end, and up to three additional follow-up meetings. There may also be an in-person meeting near the end of the study. Partners for these activities include Project Angel Food and United American Indian Involvement (UAII). Each of the four virtual classes will be held for 90-minutes through the Zoom platform. Each participant will be part of a 180-day cohort. Participants will complete surveys and attend three clinic visits as part of the study.

The aim of this study is to evaluate the effectiveness of an online intervention for people with type 1 diabetes who present not optimal control of the disease.

Every person with type 1 diabetes needs personalized advice to integrate physical activity into daily diabetes management. The purpose of this study is to collect data on food intake, physical activity, glucose levels and insulin delivery from people with type 1 diabetes who are physically active. At least 25 people with type 1 diabetes will be asked to perform 25 sports activities of at least half an hour, wear an activity tracker (day and night) and chest strap (during sports activities), and log data on food intake, periods and type of physical activity, and feelings (e.g., sick, stress) in a diary app. Diabetes data such as insulin administration and sensor data will be collected through diabetes management platforms. The primary endpoint involves a database containing data on glucose, insulin administration, physical activity, and food intake of people with type 1 diabetes for statistical analyses and visualizations regarding the relationship between physical activity and blood glucose response.

Diabetes type two is a debilitating disease that leads to chronic morbidity such as accelerated microvascular disease. Accelerated microvascular disease may produce blindness, end stage renal disease, myocardial infarction, stroke, and limb ischemia. Strategies to prevent or delay microvascular disease have the potential to improve the lives of millions and prevent catastrophic illness. The major focus of prevention of microvascular disease in diabetes has been on the endothelium and its role in protection of blood vessels. An unexpected means to prevent microvascular disease in diabetes may be coupled to the function of vitamin C in red blood cells (RBCs) of diabetic subjects. Based on new and emerging data, vitamin C concentrations in RBCs may be inversely related to glucose concentrations found in diabetes. Based on animal data, we hypothesize that RBCs with low vitamin C levels may have decreased deformability, leading to slower flow in capillaries and microvascular hypoxia, the hallmark of diabetic microangiopathy. Low vitamin C concentrations in RBCs of diabetic subjects may be able to be increased, by using vitamin C supplements. Findings in animals may not accurately reflect effects in humans because of species differences in mechanisms of vitamin C entry into RBCs. Therefore, clinical research is essential to characterize vitamin C physiology in RBCs of diabetic subjects. In this protocol we will investigate physiology of vitamin C in RBCs of diabetic subjects as a function of glycemia, without vitamin C supplementation (stage 1) and with vitamin C supplementation (stage 2). We will screen type II diabetic subjects on insulin and/or oral hypoglycemic medication(s) and select those with hemoglobin A1C concentrations of less than or equal to 12%. Selected subjects may be hospitalized twice, each time for approximately one week. The primary objective of the first hospitalization (stage 1) will be to evaluate the effect of hyperglycemia on vitamin C RBC physiology regardless of baseline vitamin C concentrations (without any vitamin C supplementation). The second hospitalization (stage 2) investigates the effect (if any) of vitamin C supplementation to changes in RBC physiology during euglycemic and hyperglycemic states. As inpatients, subjects will have two venous sampling periods each of approximately 24 hours. On admission, subjects may be fitted with continuous glucose monitors (CGMs), oral hypoglycemic agents will be discontinued, and basal-bolus insulin regimen initiated. Insulin doses will be clinically determined and titrated to achieve euglycemia (fasting and pre-meal glucoses <140mg/dl) prior to the first sampling period (euglycemic sampling). The first sampling period will be performed under conditions of euglycemic control for 24 hours. The second sampling period will be performed under controlled hyperglycemia induced by withholding basal and bolus insulin and providing a high carbohydrate load diet (70-75% carbohydrate). Correction-scale insulin will be provided for glucoses >350-400mg/dl. Hyperglycemia will not exceed 9 hours, and will be reversed by reinstituting insulin. During the two sampling periods, samples will be withdrawn via venous catheter for RBC deformability, vitamin C concentrations and other related research studies. Following completion of stage 1, subjects considered for participation in stage 2 will be provided a prescription for vitamin C 500mg twice daily. Given that vitamin C and vitamin E are related antioxidants, and that both vitamins appear to be associated with RBC rigidity, diabetic subjects may also be given a prescription for 400 international units (IU) of vitamin E (RRR alpha tocopherol) daily. Subjects will continue vitamin C and E supplementation for a minimum of 8 weeks depending on RBC vitamin C concentrations. To evaluate any effect of vitamin E supplementation, plasma and RBC vitamin E levels may be measured concurrently with vitamin C levels during various phases of stages 1 and 2. All subjects will be seen as outpatients at biweekly or monthly intervals with regular measurement of plasma and RBC vitamin C concentrations. Target RBC vitamin C concentration >30uM is required prior to stage 2 inpatient sampling studies. Vitamins C and E supplementation will be discontinued upon inpatient admission for stage 2. Risk of both vitamin supplements are minimal as both supplementation doses are safe. Outcomes are to measure RBC rigidity and vitamin concentrations before and after supplementation. After a minimum of 8 weeks (depending on RBC vitamin C levels), subjects will be hospitalized again, and sampling repeated as described. In this manner, each subject serves as his/her own control, and deformability of red blood cells can be determined in relation to glycemia and to vitamin C concentrations in RBCs and plasma.

Diabetes distress has been identified as one of the largest contributors to the racial disparity in glycemic control that disproportionately burdens Black patients ages 18-30 years with type 1 diabetes (T1D). In order to combat this issue, this study assesses the feasibility of the culturally tailored intervention T1DES and evaluates the effect of the T1DES intervention on diabetes outcomes in a pilot randomized clinical trial among Black young adults with T1D.

Evaluation of Efficacy and Safety of Curalin As Add-On Therapy in Adults with Type 2 Diabetes Mellitus

The purpose of this research study is to evaluate a transition preparation program designed for adolescents and young adults (AYAs) with type 1 diabetes (T1D). This transition program will support AYAs as they prepare to transition from pediatric to adult endocrinology medical care and will also include a caregiver. Results from this study will inform clinical recommendations regarding self-management best practices for AYAs with T1D prior to transitioning to adult medical care.
