24 Clinical Trials for Various Conditions
Certain types of rice have more dietary fiber than others. This type of rice is known a "high amylose rice." This study hypothesizes that high-amylose rice, will decrease blood glucose and insulin responses after consumption compared to conventional rice in healthy adults, ages 18-40. Eighteen healthy men and women will participate in this study. This study will determine how high blood glucose and insulin values rise after eating a portion of rice. This study will also evaluate hunger ratings after consuming rice. The results of this study will help researchers better understand how diet can influence diabetes management.
This pilot study will evaluate the effects of the anti-diabetic drug Bydureon (exenatide extended-release formulation) on blood sugar levels and serum markers of inflammation in a cohort of 12 HIV-infected adults on combination antiretroviral therapy (cART) with untreated diabetes mellitus. Previous studies have shown that high levels of persistent systemic inflammation predict the development of cardiovascular and metabolic diseases in HIV-infected persons on cART (a group at very high risk of atherosclerosis and myocardial infarction). Bydureon has demonstrated potent anti-inflammatory effects in prior studies of non-HIV infected persons, which suggests that this agent may represent a unique and preferred medication for the treatment of insulin resistance in HIV-infected adults. The Investigators hypothesize that short-term (16 weeks) therapy with Bydureon will improve glucose tolerance and significantly reduce circulating plasma levels of interleukin-6 (IL-6) and highly-sensitive C-reactive protein (hsCRP), two biomarkers strongly implicated in the development of cardiovascular and metabolic diseases in diabetic, HIV-infected, cART-treated adults.
The Livongo-Insulia Study App Pilot Study (LISA Pilot) is a 3-month, prospective, interventional study. The purpose of this pilot study is to evaluate the feasibility of using the Livongo-Insulia Study App for individuals with type 2 diabetes using basal insulin. This will be assessed by measuring the impact of the Livongo-Insulia Study App on glycemic control for these individuals.
The TREAT Pilot is a 3 months open-label pilot study to examine the effect of restricting the duration of eating (Time Restricted EATing) in metabolically unhealthy adults with overweight or obesity. This pilot study will allow the investigator to collect preliminary data for the design of a larger study.
This study is designed to learn if hemin can increase the production of heme oxygenase 1 and improve gastric (stomach) emptying and symptoms in diabetic patients with slow gastric emptying (gastroparesis).
PROTOCOL SUMMARY Type of Study: Pilot, randomized and single center trial Test Procedure: Omentectomy Aim 1. Determine the effect of omentectomy on 1) insulin sensitivity, 2) beta cell function and 3) plasma markers of inflammation We hypothesize that removal of omental fat increases insulin sensitivity and pancreatic sensitivity to glucose, and decreases systemic inflammation. Aim 2. Identify genes and proteins in adipocytes from obese patients that affect clinical presentation versus those that are affected by obesity for future study. We hypothesize that the genetic samples will help us to identify genes and proteins in adipocytes from obese patients that affect clinical presentation versus those that are affected by obesity and help us to design future obesity genetic studies. Total Enrollment Number: 30 patients who are scheduled to undergo bariatric surgery for weight loss at New York University Medical Center will be invited to participate in this study. Subjects will be randomly assigned, by using a computer-generated randomization scheme, in a single-blind fashion to either the omentectomy (n=15) or control group (n=15).
16-week, open-label, multi-center pilot study. Insulin pump naïve subjects with type 2 diabetes who are not achieving glycemic targets (screening A1C ≥ 7.0%) on an established regimen of either: 1) ≥ 2 OAs (Cohort A), 2) basal insulin ± OAs (Cohort B), or 3) basal-bolus insulin ± OAs (Cohort C) will initiate basal-bolus therapy with an insulin pump using a rapid-acting insulin analog.
The main objective of this study is to develop and evaluate a clinic-based pilot intervention to optimize patient-centered diabetes care for low income patients at risk for low quality diabetes care and poor outcomes.
This is a single arm open label pilot clinical trial that will assess patient-reported blood glucose levels before and after using the Control:Diabetes mobile app, while collecting user feedback and recommendations for further improvements to the app functionality and user interface. This study will enroll approximately 70 individuals with insulin-treated diabetes mellitus. The study will include two online surveys (baseline and exit), one study initiation phone call, and will also collect data entered by the users into the mobile app.
The Ahmanson-UCLA Cardiomyopathy Center is conducting a clinical research study that will assess the use of the medication metformin to improve quality of life, exercise capacity, and improved outcomes in heart failure patients with pre-DM or early DM (type II). If the patient participates in this study, the patient will receive the drug metformin for approximately 3 months. During the study the patient will undergo comprehensive testing which includes blood draws and echocardiograms. The patient will also fill out a questionnaire. The patient must be 18 years old to participate.
This pilot study will evaluate the safety and effectiveness of leptin therapy in two children with severe insulin resistance syndrome. Patients with this condition often have high blood sugar levels and may have hormone imbalances, a constant feeling of warmth, fertility problems, large appetite, and enlarged liver due to fat accumulation. Leptin is a hormone produced by fat cells. It influences appetite, affects levels of reproductive hormones, and possibly manages how the body reacts to insufficient food. Certain people with severe insulin resistance syndromes have decreased amounts of fat tissue and make little or no leptin. A 13-year-old male and an 11-year-old female with severe insulin resistance will participate in this study. They will have the following tests and procedures before beginning 4 months of leptin therapy: * Insulin tolerance test - measures blood sugar levels after intravenous (IV) administration of insulin. Blood samples are collected through the IV tube at various intervals during the 1-hour test. * Ultrasound of the liver and, if abnormalities are found, possibly liver biopsies. * Fasting blood tests - to measure blood count, blood lipids, and various hormones and assess liver function. * Resting metabolic rate - to measure the amount of oxygen breathed at rest in order to calculate how many calories are required to maintain resting body functions. * Magnetic resonance imaging of the liver and other organs, and of muscle and fat. * Pelvic ultrasound in female patient - to detect ovarian cysts. * Estimation of body fat - measurements of height, weight, waist, hip size, and skin folds over the arms and abdomen to estimate body fat content. * Oral glucose tolerance test - measures blood sugar and insulin levels. The patient drinks a very sweet drink containing glucose (sugar), after which blood samples are collected through an IV tube in an arm vein at various intervals during the 3-hour test. * Intravenous glucose tolerance test - measures tissue response to insulin and glucose after glucose injection and insulin infusion. Blood is collected over 3 hours to measure insulin and glucose levels. * Appetite level and food intake - to measure hunger level and caloric intake. Patients are questioned about their hunger level, given a variety of foods they may choose to eat and questioned again at various intervals about hunger level. On another day, patients are given breakfast (usually a milkshake) and when they want to eat again, the appetite level and caloric intake study is repeated. * Hormone function tests - the function of three hormones influenced by leptin (corticotropin-releasing hormone, thyrotropin-releasing hormone and luteinizing hormone-releasing hormone) are assessed. The hormones are injected intravenously and then blood samples are drawn. * Questionnaire - patients complete a questionnaire about their activities and how they feel. * 24-hour urine collections - to measure specific hormones, proteins and sugars excreted in the urine. When the above tests are completed, leptin therapy will start. The drug is injected under the skin twice a day for 4 months. Patients will record their symptoms weekly throughout the study. Those with diabetes will measure their blood glucose levels daily before each meal and at bedtime. Follow-up visits at 1, 2 and 4 months after therapy will include a physical examination, blood tests and a meeting with a dietitian. At the 4-month visit, the tests done at the beginning of the study will be repeated.
This is a prospective, single arm, open-label, single-center pilot study to assess the safety, feasibility, and efficacy of Stem Cell Educator therapy for the treatment of patients with Type 1 Diabetes.
The purpose of this study is to provide the necessary data and experience to design a larger, full scale clinical trial to determine if a certain medicine (repaglinide), which increases the amount of insulin secreted by the pancreas, can improve the nutritional status and pulmonary function of adolescents and young adults with cystic fibrosis and prediabetes by improving blood glucose control. The investigators are also trying to determine the relationship between systemic inflammatory factors and glucose impairment.
The objective of this study is to compare the reduction in wound surface areas between patients with diabetic ulcers utilizing Provant's pulsed radio frequency energy therapy (PRFE) as an adjunct to standardized basic wound care to those utilizing standardized basic wound care alone.
This study will compare the side effects of two laser treatments for diabetic macular edema, a common condition in patients with diabetes. In macular edema, blood vessels in the retina, a thin layer of tissue that lines the back of the eye, become leaky and the retina swells. The macula, the center part of the retina that is responsible for fine vision, may also swell and cause vision loss. Traditional laser treatment (argon blue or green, or yellow) for macular swelling, or edema, causes scarring that can expand and possibly lead to more loss of vision. A different laser technique, the mild macular grid, uses lighter laser burns through the macula and may be less damaging to the eye, but this is not known. This study will compare the two techniques and the information on side effects will be used to design a larger study of whether one laser is more effective than the other. Patients 18 years of age and older with type 1 or type 2 diabetes and macular edema may be eligible for this study. Candidates will be screened with the following tests and procedures: * Medical history and physical examination. * Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils will be dilated with drops for this examination. * Blood tests to measure cholesterol levels, hemoglobin A1C (a measure of diabetes control), and creatinine (measure of kidney function). * Eye photography to help evaluate the status of the retina and changes that may occur in the future. Special photographs of the inside of the eye are taken using a camera that flashes a bright light into the eye. * Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. * Optical coherence tomography to examine retinal thickness. The eye is examined with a machine that produces cross-sectional pictures of the retina. These measurements will be repeated during the study to determine whether retinal thickening is getting better, worse, or staying the same. Participants will be randomly assigned to one of the two laser therapies in the eye with macula edema. (Patients with macular edema in both eyes will receive both treatments-one in each eye.) For these procedures, eye drops are put in the eye to numb the surface, and a contact lens is placed on the eye during the laser beam application. Several visits may be required for additional laser treatments. The number of treatments depends on how well they are working. Patients will return for follow-up visits 4, 8, and 12 months after the first treatment, and then every year until year 3. During the follow-up visits, the response to treatment will be evaluated with repeat tests of several of the screening exams.
This research project will investigate the effects of pramlintide (Symlin) given by continuous subcutaneous (under the skin) infusion throughout the day and night, along with meal doses similar to those injected during conventional pramlintide (Symlin) treatment, delivered using a second insulin pump, in subjects with inadequately controlled type I diabetes mellitus who are already using insulin pump therapy. Study participants will wear two pumps for a four month period, taking insulin in their usual manner and pramlintide (Symlin) in a similar basal/bolus fashion. Continuous glucose monitors will be worn on three occasions during the study to assess blood glucose responses to continuous pramlintide (Symlin) treatment.
Pioglitazone is an approved anti-hyperglycemic medication and is thought to have anti-inflammatory properties. This study seeks to gather safety and tolerability data related to pioglitazone when given to patients who require hospital admission for confirmed positive COVID-19 infections with elevated blood sugar levels as compared to patients who did not receive pioglitazone during their hospitalization for COVID-19.
The purpose of this two phase study is to: 1) develop and 2) assess a program titled: Merging Yoga, Occupational Therapy and Nutrition Education (MY-OT-Ed) designed for low income adults with Type 2 Diabetes. Half of the participants will participate in the Nutrition Education, and the other half of the participants will participate in Nutrition Education plus Occupational Therapy group and group yoga.
This study will examine the feasibility of implementing a clinician-supported patient self-managed inpatient insulin intervention. It will: assess the number of eligible patients presenting over time; assess patients' willingness to enroll; assess patients' ability to successfully complete the intervention; examine occurrences of hyperglycemia and hypoglycemia; and assess patients' satisfaction with inpatient diabetes care.
Primary aim: examine feasibility and acceptability of a brief cognitive therapy protocol for type II diabetes administered by nurse care managers or health coaches via phone.
The objective of this study is to investigate the safety and efficacy of minocycline as a microglia inhibitor in individuals with diabetic macular edema (DME).
The purpose of this study is to determine if intravitreal infliximab is a safe and effective treatment for macular edema secondary to diabetes.
The rationale for the study is to determine if Campath-1H can be used in patients recently diagnosed with type I DM, to induce a state of immunological unresponsiveness such that subjects can safely preserve beta cell mass and eliminate or lower insulin requirements, preserving excellent metabolic control.
This research study is being performed to begin to determine the effectiveness of two dominant bariatric surgery procedures versus an intensive lifestyle intervention to induce weight loss in patients and promote improvements in Type 2 diabetes mellitus (T2DM) in moderately obese patients. T2DM is currently the 6th leading cause of mortality in the United States and is a major cause of kidney failure, blindness, amputations, heart attack, and other vascular and gastro-intestinal dysfunctions. Traditionally, treatments include intensive lifestyle modifications with or without glucose lowering agents. Neither treatment alone, or in combination, results in complete resolution of diabetes and its potential long-term complications. Bariatric surgery has been proven as an effective treatment to accomplish sustained and significant weight loss for those with severe obesity and has been shown to induce long-term remission of T2DM. However, despite enthusiasm for these potential treatment options, it is not clear whether diabetes is influenced by the type of surgery or by the amount of weight lost or if bariatric surgery is more effective than non-surgical weight loss induced by diet and physical activity in T2DM patients with moderate BMIs (30-40kg/m2; Class I and Class II obesity, or approximately 65-95 pounds overweight depending on your height). More well-controlled studies are needed to more completely inform health care decision making and clinical practice in this area. This research study aims to obtain preliminary information regarding the effectiveness of two major types of bariatric surgery, Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding versus an intensive lifestyle intervention to induce weight loss with diet and increased physical activity.
