Diabetes Mellitus Clinical Trials

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.

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

The purpose of this study is to gain more information about the step-by-step process that causes someone to develop type 1 diabetes. Scientists think that a person's own immune system, directed by genetic and environmental factors play a major role in its development. Participation involves a blood draw, a brief medical history questionnaire and measurements of height and weight. Some participants will be asked to return for annual follow-up visits for 10 years.

The T1D Exchange Registry is a research study, conducted over time, for individuals with type 1 diabetes and their supporters. Participants volunteer to provide their data for research (for example, by answering questions in annual surveys). Once enrolled, Registry participants have the opportunity to sign up for other studies on various topics related to type 1 diabetes. To participate, you will be asked to: Read and sign an online informed consent form Take a survey describing specific demographic and type 1 diabetes management information Update your information annually Periodically opt in for additional research opportunities (if you choose), i.e. taking new surveys or uploading health device data Read Less

The specific aims are to: Identify and enroll individuals and families with undiagnosed rare and atypical forms of diabetes. Determine the etiologic basis of the metabolic disorder among individuals and families with novel forms of rare and atypical diabetes. Understand the pathophysiology of individuals and families with novel forms of rare and atypical forms of diabetes. Read Less

Inadequate rehabilitation training after amputation can result in poor patient outcomes, injuries, and wasted healthcare resources. This is a serious public health problem due to an aging population and rising prevalence of diabetes (main cause of amputation in the U.S.). In this study, the investigators will examine the effects of external vs. internal attentional focus instruction on learning of a balance task in individuals with existing amputation and those at risk of amputation (older adults with diabetes). With the proposed research, the investigators aim to expand the understanding of motor learning in individuals with and at risk of lower limb loss to provide knowledge that will lead to more effective and efficient rehabilitation.

A high prevalence of diabetes has been reported in Qatar with nearly 23% population suffering from the pandemic, thereby increasing the associated healthcare cost. Low compliance with exercise and physical activity in patients with diabetes increases foot risk complications, deteriorates health, and further increases economic costs. This is particularly true among patients with diabetes who are undergoing hemodialysis (HD) process. Exercise interventions have been shown to improve mobility and balance, reduce the incidence of falls, and improve peripheral blood flow, which is essential to reduce foot problems and peripheral arterial disease. However, uptake of exercise programs for individuals who are undergoing HD treatment has been limited. The three main factors limiting uptake and adherence among HD patients are time availability, post-dialysis fatigue, and transportation to exercise programs, which are usually offered in rehabilitation departments or cardiovascular centers but not in nephrology departments or in free-standing dialysis clinics. Many of these patients visit clinics 3 times a week to receive hemodialysis, providing an optimal opportunity for intervention. Thus the investigators are proposing an innovative intervention based on plantar electrical stimulation treatment during HD (3 times per week) to enhance balance and quality of life while reducing the risk of peripheral arterial diseases and diabetic foot ulcers, which are highly prevalent among people with diabetes and chronic kidney disease. This interdisciplinary study is based on preliminary studies, in which the investigators demonstrated that regular plantar electrical stimulation is an effective and practical therapy to enhance motor performance and plantar sensation in patients with diabetes. The scientific premise of the proposed intervention has been also supported by literature as well as three systematic reviews suggesting the effectiveness of electrical stimulation to reduce pain, improve balance, improve skin perfusion, and improve plantar sensation. In the context of this study, the investigators propose to bring an innovative technology based on an FDA-cleared bio-electric stimulation technology (BEST®) microcurrent platform, named Tennant Biomodulator® (Avazzia Inc., Dallas, TX, USA), which is a transcutaneous electrical nerve stimulator (TENS) and has been designed for symptomatic relief and management of chronic pain. However, the system was modified to provide electrical stimulation to the plantar area via two electrodes placed on the hind and forefoot area instead of the leg. The device has a 60-minute run cycle after which it automatically turns off. In the context of a previous study funded by QNRF, the investigators developed and tested 50 electrical stimulation units (which will be used in the context of the study), including 25 active systems and 25 placebo systems. The placebo systems are similar to active systems in the appearance and functioning of lights and indicators. However, they were programmed not to provide any electrical current. In a preliminary study, the proof of concept of this revised technology was tested in the context of enhancing balance and skin perfusion in ambulatory patients with diabetes and peripheral neuropathy. In the context of this study, the investigators plan to translate this technology for routine treatment during HD sessions for patients with diabetes who are undergoing regular HD treatment. Using a double-blinded randomized-controlled model, the investigators will validate the effectiveness of this technology to enhance balance, reduce pain, and improve skin perfusion. One hundred (n=100) HD volunteers with diabetes will be recruited and randomized to either intervention (n=50) or control (CG: n=50) group for the purpose of this study. Plantar electrical stimulation will be provided during HD sessions, 3 times per week and for 12 weeks. Outcomes will be assessed at baseline, 6 weeks, and 12 weeks to examine the effectiveness of the proposed intervention to enhance balance, improve quality of life, and improve lower extremity skin perfusion among HD patients with diabetes. This proposal is in line with Qatar National Priorities Research goals and if successful the result will open new doors to managing diabetes and kidney failure. In a setting where no therapeutic agents or interventions effectively address poor balance and loss of protective sensation among HD patients with diabetes and where affected individuals life with a heightened risk of developing a debilitating foot ulcer and quite possibly a disabling amputation, the potential impact from the plantar electrical stimulation system may offer the potential for significant clinical benefit, with very low risk, and with ease of implementation in routine care application for patients who are undergoing HD treatment.
