Active clinical trials for "Diabetes Mellitus, Type 2"

This study is for women who have already decided to undergo liposuction at Georgetown University Medical Center in Washington, D.C. To take part in this study, a woman must first meet with the plastic surgeons there, and be accepted by them to have liposuction. This study will investigate whether large volume liposuction improves risk factors for heart disease in overweight women with type 2 (adult onset) diabetes, impaired glucose tolerance, or elevated blood insulin levels. Large volume liposuction is the surgical removal of at least 10 pounds (4.5 kg) of body fat, usually from the abdomen, hips or chest. Risk factors for heart disease include high blood pressure and elevated levels of blood lipids (cholesterol and triglycerides), blood glucose (sugar), and blood insulin. Subjects who participate in all parts of this study will receive a total of $930.00. Overweight women 18 years or older with high blood insulin levels, impaired glucose tolerance, or type 2 diabetes, who are planning to have large volume liposuction performed at Georgetown University Medical Center in Washington, D.C., may be eligible for this study. For a subject to be accepted into this study, she must first meet with the plastic surgeons at Georgetown University Medical Center, and they have to agree to perform large volume liposuction. The decision that someone is suitable for liposuction is not under the control of the NIH or of any NIH investigator. Those enrolled will undergo the following procedures at four separate times - before undergoing liposuction, 4 weeks after surgery, 4 months after surgery and 1 year after surgery: Body measurements - taken with calipers to measure several skinfold thicknesses (the width of a fat fold) and with a tape measure to measure the circumference of parts of the body. Urine sample and 6-hour urine collection - to test for pregnancy and to evaluate kidney function. Glucose tolerance test - measures insulin sensitivity and how the body uses sugar, how well insulin works, and insulin sensitivity. The procedure involves placement of two catheters (thin, flexible tubes) through a needle into a vein in each arm. Sugar water is infused into one catheter and 20 minutes into the test a small amount of insulin is injected. Blood samples are drawn from the other catheter at frequent intervals for a total of 5 hours. Electrocardiogram (ECG) and echocardiography - measure the heart's electrical activity and function. Abdominal computerized tomography (CT) scan - produces images for measuring body fat in the abdomen. (not done at the 4-week visit). Takes about half an hour to complete. DXA X-ray - measures body fat, muscle and bone mineral content. Takes about half an hour to complete. Bod Pod - capsule-like device used to determine the proportion of body weight composed of fat and non-fat tissue. Takes less than 10 minutes Bioelectric impedance analysis device - measures the proportions of body fat based on electrical conduction of a small electric current. Takes 2-3 minutes. 24-hour blood pressure monitoring - a device attached to a blood pressure cuff strapped to the arm measures blood pressure every 15 to 30 minutes continuously for 24 hours. Vascular reactivity tests - a blood pressure cuff is inflated for about 4 minutes before deflating, providing information on the function of the small blood vessels in the skin, as well as an idea of the function level of small blood vessels elsewhere in the body. Takes half an hour. Blood samples - collected to evaluate kidney and liver function and to measure body lipids, such as cholesterol, minerals, and other substances.

Patients with high blood pressure, diabetes, and who are overweight are known to have defects in the way their body responds to insulin. The purpose of this study is to develop better methods for measuring the way body tissue responds to insulin and sugar (glucose). Researchers are planning to study four groups of patients. Normal volunteers Patients who have mild to moderate high blood pressure Patients who are overweight Patients who have mild to moderate diabetes controlled with oral medication In this study patients and volunteers will undergo two separate tests designed to determine how well insulin is working in the body. The first test is called a glucose clamp test. Patients will have two needles placed in the veins of their arms. One needle will be used to take blood samples, the other needle will be used to inject doses of sugar (glucose) and insulin. The second test is called the frequently sample intravenous glucose tolerance test. In this test patients will have sugar (glucose) injected into their veins followed by a slow injected dose (infusion) of insulin. Researchers will periodically take blood samples during the test. Patients participating in the study will not directly benefit from it. However, the information gained from this study may be useful for improving the diagnosis and therapy of diseases such as diabetes, obesity, and high blood pressure (hypertension).

To determine the incidence of type II diabetes and cardiovascular disease among Mexican-American and non-Hispanic whites in a 15 to 24 year follow-up of the San Antonio Heart Study 1 participants. Also, to perform a 15 to 24 year mortality follow-up of the cohort and to examine the "Hispanic paradox".

Replication of three clinical trial emulations CANVAS, LEADER, and SAVOR TIMI that form part of the RCT-Duplicate initiative, sponsored by the FDA and delivered by the Brigham and Women's Hospital and Harvard Medical School. AstraZeneca will use the Instant Health Data platform PANALGOS (IHD) for the analyses.

This study was conducted to evaluate the effect of individual insulin use training given to patients with type 2 diabetes using insulin on safe drug administration, pain level and perception of treatment. The study was conducted between October 2022 and March 2023 with a randomized control group.

An observational study to collect data on the efficacy, safety, usability, and quality of life/psychosocial effects of the community-derived OS-AID Loop System on adults with type 2 diabetes.

Background: Due to lack of clear symptoms, type 2 diabetes can remain undetected for many years. Our aim was to explore the capacity of Norwegian community pharmacies to identify people at high risk of developing type 2 diabetes and the impact of the risk assessment service on self-rated health. Methods: Nineteen community pharmacies were randomly allocated to a diabetes risk test only- group or Haemoglobin A1c (HbA1c) -group were the participants with a high risk of developing type 2 diabetes also received a HbA1c-measurement. Two pharmacists at each pharmacy were trained to perform risk assessments and counselling. The pharmacists at the 11 HbA1c pharmacies were also trained in how to perform the HbA1c- measurement. During six months, pharmacy customers equal or over 45 years old, wishing to participate contacted the pharmacy staff. Participants completed a validated diabetes risk test and a background questionnaire including a validated instrument for self-rated health. In the risk test only-group, participants with a high risk of developing type 2 diabetes were referred to their general practitioner for follow-up, while in the HbA1c-group, participants with HbA1c ≥ 48 mmol/ mol (6.5%) were referred to their general practitioner.

The number of people with diabetes is rising. One of the major causes of premature death in diabetes is heart failure (HF). This is when the heart cannot pump blood effectively, and this may be related to abnormalities in energy production in the heart muscle. In healthy people, the heart muscle cells show flexibility and can use both sugar and fat molecules for energy production. Although burning fat provides more energy, this process requires more oxygen than burning sugars. As a result, fat is a less efficient fuel for the heart compared to sugars, especially in situations where the energy and oxygen needs are higher, such as during exercise. The investigators propose that the heart muscle in patients with type 2 diabetes relies heavily on fat for energy provision, and fails to burn more sugar molecules for energy provision during exercise to more efficiently use oxygen. Fat and sugar uptake by the heart can be detected by the difference between the blood sugar and fat levels delivered to the heart and returning from the heart, both at rest and also when the heart is working faster during Dobutamine infusion. Dobutamine is a drug frequently used to mimic exercise, and get the heart running faster during medical tests. To test the hypothesis, the investigators will assess fat and sugar uptake by the heart at rest and when the heart is running faster, in patients with type 2 diabetes undergoing investigations to rule out coronary disease. Heart function, and blood supply to heart muscle, at rest and during Dobutamine infusion, will also be measured using MRI scanning. The same tests will be performed in people without diabetes for comparison. It will help understand diabetic heart disease and which aspects may be targeted with new treatments.

C-peptide is used to evaluate beta cell reserves. Patients with type 2 diabetes are treated with insulin for different indications. Other than beta-cell insufficiency and organ failures, insulin treatment is needed for a specified period. The investigators want to evaluate beta cell reserves in patients with type 2 diabetes treated with insulin for at least six months to see if that is the case. The investigators also want to compare the characteristics of these patients according to their beta cell reserves.

The main purpose of this study is to learn more about how tirzepatide affects the body's response to low blood sugar (hypoglycemia). The study is open to participants with type 2 diabetes. It will last about 42 weeks for each participant.
