NCT06376240
Patients with type 2 diabetes have an increased risk of developing vascular complications. Microvascular dysfunction might be caused by the increased production of methylglyoxal under hyperglycaemic conditions. Methylglyoxal is a by-product of glycolysis and forms advanced glycation endproducts (AGEs) on proteins and DNA, thereby disrupting their function. Preventing methylglyoxal accumulation and AGEs formation may offer a therapeutic option for treating microvascular complications in diabetics. Pyridoxamine is a vitamin B6 vitamer that scavenges methylglyoxal and thereby inhibits the formation of AGEs. In this study, the researchers investigate whether pyridoxamine supplementation in type 2 diabetes improves microvascular function in the eye, kidney and skin, and reduces markers of endothelial dysfunction and glycation.

Background: Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates may not work well for all people. Researchers want to find more accurate ways to measure a person s metabolism. Objective: This natural history study will examine the relationships between metabolism, body composition, and body surface area in a wide range of people. Eligibility: Healthy children and adults aged 2 years or older. Also, people aged 2 years or older with conditions that may alter metabolism. These may include diabetes, obesity, renal disease, or cancer. Design: Participants will spend 2 days and 1 night in the hospital. They will provide a medical history and answer questions about their activity levels, the foods they eat, and their lifestyle. They will also eat a special diet. Participants will undergo many tests: They will lie in a bed with a clear hood covering their head for 30 to 45 minutes to measure the gases in their breath. They will lie on a padded table for about 15 minutes while their body is scanned. They will stand on a platform while a 3D scanner measures their body. They will have a test to measure how fast an electric signal moves through their body. They will grip an instrument to measure the strength of their hands. They will drink salty water and provide blood and urine samples. Participants may be invited to return for these 2-day visits up to 8 times per year. Return visits must be at least 2 weeks apart.
NCT05734989
In Aim 1 of this study, the investigators will utilize community organizations to screen Hispanics/Latino(a)s for kidney disease, diabetes, and other risk factors, and refer them for care with a PCP. In Aim 2, the investigators will implement an intervention in local health clinics to assist PCPs with screening and treating Hispanic and Black patients with diabetes. Completion of the project will hopefully slow progression of kidney disease among Hispanic/Latino(a) and Black patients in Durham, and the information gained will allow the investigators to eventually perform the intervention on a larger scale.
NCT00065676
Quercetin is a compound naturally found in various foods. It may have some role in the treatment of obesity and diabetes. The purpose of this study is to investigate research volunteers with obesity or obesity with type 2 diabetes to determine whether quercetin affects the way glucose is absorbed by the body. Thirty two participants aged 19 to 65 who are considered to be medically obese or obese with type 2 diabetes will be enrolled in this study. Before the onset of treatment, they will undergo a medical history, physical exam, blood work, and urinalysis. During the study, participants will be given an oral glucose tolerance test three times; during these tests they will receive 1 or 2 grams of quercetin, or placebo. Researchers will collect blood samples and analyze the effect of the treatment on blood glucose.
NCT01105858
Background: \- Family and twin studies have suggested that genetic factors influence approximately 50 percent of a person's susceptibility to type 2 diabetes. Recently, some of the genes involved in the development of type 2 diabetes have been identified, in large part by genome-wide association studies. Certain risk factors for type 2 diabetes, such as obesity and insulin resistance, are highly inheritable, as are diabetic complications such as diabetes-related eye and kidney disorders. However, few genes associated or linked with diabetes risk factors or complications have been conclusively identified, and more research is needed to study specific genetic factors associated with these aspects of diabetes. Objectives: \- To identify and characterize genetic variants associated with type 2 diabetes, its risk factors, and its complications. Eligibility: \- Individuals at least 18 years of age who are not pregnant or nursing mothers at the start of the study. Design: * All participants will provide information about family history, ethnicity and ethnic background, occupation, behavioral risk factors, and other data as requested by the researchers. * In addition to a general health history, participants will provide specific information about diabetes history, with particular emphasis on date of diagnosis, symptoms, initiation of insulin therapy, complications, and current medications. * Testing procedures will be different for individuals with and without diabetes. Those without diabetes will have an oral glucose tolerance test, while those with diabetes will be examined for diabetic complications. * Other tests during the study will include the following: * Physical examination with measurements of height and weight, waist circumference, blood pressure, and other tests for individuals who have been diagnosed with diabetes * Glucose tolerance test for those who have not been classified as having diabetes * Retinal photographs * Electrocardiograms * Hepatic Ultrasound * Blood and urine tests * Depending on the results of the examination and laboratory findings, participants may be asked to return to the clinic for supplemental interviews, physical examinations, or blood tests, or to arrange referrals for medical evaluation and treatment. * Participants who have diabetes will be asked to return for yearly follow-up visits. Participants who do not have diabetes at the initial examination will be asked to return for follow-up visits every 2 years.

NCT06066528
This study is open to adults who are at least 18 years old and have a body mass index of 27 kg/m² or more. People can take part if they have type 2 diabetes and if they are currently being treated only with diet and exercise or with specific diabetes medications. Only people who have previously not managed to lose weight by changing their diet can participate. The purpose of this study is to find out whether a medicine called survodutide (BI 456906) helps people living with overweight or obesity who also have diabetes to lose weight. Participants are divided into 3 groups by chance, like drawing names from a hat. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under their skin once a week for about one and a half years. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 1 year and 7 months. During this time, it is planned that participants visit the study site up to 14 times and receive 6 phone calls by the site staff. The doctors check participants' health and take note of any unwanted effects. The study staff also regularly measure participants' body weight. The results are compared between the groups to see whether the treatment works.

The main aim of this study is to compare 2 different measurements of visceral fat that can be easily used in clinical practice (waist circumference versus bioelectric impedance) in relation to known risk factors of coronary artery disease in a large cohort of patients with type 2 diabetes and with a BMI range between 20-45 kg/m2
NCT07525882
This observational cross-sectional study aims to investigate the effects of glycemic control and clinical parameters on tibial nerve conduction latency in individuals with diabetic peripheral neuropathy. Adults aged 45 to 76 years with diabetic peripheral neuropathy will be evaluated at a neurology and clinical neurophysiology clinic. Data collection will include demographic and clinical characteristics, diabetes type and duration, fasting blood glucose, and HbA1c values obtained from routine clinical records. Participants will also be assessed using the Michigan Neuropathy Screening Instrument (MNSI), including both the questionnaire and physical examination components. Nerve conduction studies will be performed using standard electromyography procedures, and tibial nerve conduction latency will be recorded. The study will examine the relationship between tibial nerve conduction latency and glycemic control parameters, neuropathy screening scores, and diabetes duration. The findings may help improve early identification and clinical evaluation of diabetic peripheral neuropathy.
NCT07537088
The purpose of this study is to evaluate whether adding dulaglutide to the combination therapy of Sodium-Glucose Co-Transporter 2 Inhibitors(SGLT2i) and finerenone can provide additional kidney protection and safety for Chinese adults with Type 2 Diabetes Mellitus(T2DM) and Chronic Kidney Disease(CKD). Eligible participants will be adults with T2DM and mild-to-moderate CKD who have been receiving SGLT2 inhibitor plus finerenone for at least 3 months on the basis of maximum tolerated dose of renin-angiotensin system inhibitor (RASi). Participants will be randomly assigned to either continue the original regimen or to receive add-on therapy with dulaglutide.The study will last for 26 weeks, with participants required to attend scheduled visits for efficacy and safety assessments at Week 13 (±1 week) and Week 26 (±1 week, final visit).

NCT07395050
Type 1 diabetes (T1D) is a persistent and gradually increasing genetic autoimmune disease requiring life-long management. The disease commonly impacts children. However, a quarter of cases are diagnosed in adults. The pancreatic islet beta-cells are responsible for producing insulin, a peptide hormone that is involved in the tight regulation of blood glucose levels. In T1D, the beta-cells are mistakenly destroyed by autoreactive T cells resulting in insulin deficiency and an inability to regulate blood glucose levels. The cause for such an autoimmune reaction to beta-cells is under active investigation. T regulatory cells (Tregs), are specialized immune cells that typically act to control your immune system. Tregs can be modified in the laboratory to recognize and deactivate T1D-causing cells. This process is done by inserting a piece of DNA (the molecules inside cells that carry genetic information and pass it from one generation to the next) into the Tregs. A non-infectious virus called a lentivirus will carry the piece of DNA into the cells that were collected from a donor. Tregs are then grown to large numbers in the laboratory and stored for treatment of T1D. It is not known whether these Tregs cells will treat T1D.

NCT07491978
The goal of this observational study is to learn if a non-contact facial scan using artificial intelligence (AI) can be used to check health status in adults living in urban areas such as Jakarta. The facial scan uses a method called remote photoplethysmography (rPPG), which measures small changes in blood flow from the face using a camera. The main questions this study aims to answer are: 1. How close are the results from the facial scan to standard medical measurements, such as heart rate, breathing rate, blood pressure, and oxygen levels? 2. Can the facial scan estimate other health indicators, such as blood sugar, lipid profile, HbA1c, and hemoglobin levels? 3. Is there a relationship between the facial scan results and mental health, such as stress, anxiety, and depression? Participants will take part in several simple and mostly non-invasive procedures: 1. Answer questionnaires about their mental health and daily habits 2. Have basic health checks, such as blood pressure, heart rate, and body measurements 3. Provide a blood sample for laboratory testing 4. Complete a facial scan using a camera for about 1 to 3 minutes Researchers will compare the results from the facial scan with standard clinical and laboratory tests to see how well the technology works. This study may help develop a simple and accessible screening tool that can be used for early detection of health risks. It may also support the use of digital health and telemedicine in community and clinical settings.
NCT01399385
Background: \- Imaging tests, such as magnetic resonance imaging (MRI), can provide information about heart and blood vessels. The tests let doctors can see the amount of blood vessel narrowing and vessel wall thickness. This information may help diagnose and treat heart disease and other conditions that lead to heart attacks. Better MRI methods are needed to improve heart disease diagnosis, especially by avoiding the use of radiation. Researchers are testing new techniques to improve the quality of heart MRI, compared with more complex studies like catheterization or angiography. Objectives: \- To compare heart MRI techniques with other tests used to diagnose heart disease. Eligibility: \- People at least 18 years of age who either have or may have heart disease, or are healthy volunteers. Design: * Participants will be screened with a physical exam, medical history, and blood tests. * They will have an angiography to study the inside of blood vessels. This test is an x-ray study of the blood vessels. It will be done either separately or as part of a set of tests to diagnose possible heart disease. * Participants will have at least one and up to five MRI scans. The scans will involve different methods of studying the heart and blood vessels. Participants may also have a computed tomography scan to confirm the findings of an MRI scan. * No treatment will be provided as part of this protocol.
NCT06619015
The two main aims of this clinical study is; 1. To investigate if the results from a series of physiological tests and questionnaires prior to treatment, can be used to predict the treatment response to obesity medication 2. To investigate the effect of combining semaglutide and pramlintide on various aspects of appetite, food preference and eating habits. The study is planed as a 26 week, double blinded, randomized, placebo controlled trial. The goal is to include N=40. They will all receive weekly semaglutide injections. After 24 weeks they will be randomized to receive either an amylin analog (pramlintide) or placebo as a continuous infusion for two weeks, in addition to weekly semaglutide. The results from this study will contribute to identifying possible predictors of treatment response, enabling optimal individualized medical weight loss treatment. As well as providing knowledge on the complex interplay between incretin hormones and their effects on appetite and eating habits.

Type 1 diabetes (T1D) can lead to psychological adjustments that impact the acceptance and management of this health condition, as well as the overall quality of life of patients, especially among the young. Therefore, there is a need for psychological interventions aimed at enhancing the psychological well-being of children and adolescents with T1D. The goal of this non-randomized controlled trial is to evaluate whether a combined intervention comprising mHealth (using an app) and face-to-face psychological sessions based on Barlow's protocol and cognitive-behavioral therapy techniques (CBT) is effective in enhancing psychological well-being in children and adolescents with T1D. The main hypotheses are: * H1: The primary results expected to be obtained are a significant increase in psychological well-being, which means a decreased diabetes distress (DDS) (H1a) an increased subjective well-being (PANAS) (H1b) and a better self-efficacy for managing their emotions (RESE) (H1c). * H2: As secondary outcomes, it is also expected that the combined mHealth-CBT intervention would increase the level of positivity (P-Scale) (H2a), the self-esteem (RSES) (H2b) and the satisfaction with life (SWLS) (H2c).
NCT07536516
The prevalence of diabetes is increasing, with type 2 diabetes mellitus comprising over 90% of cases. Diabetes mellitus complications, including diabetic retinopathy (DR), impose significant health burdens. GLP-1 receptor agonists (GLP-1RAs) and dual GIP/GLP-1 receptor agonists show promise in improving cardiovascular and kidney outcomes, but their effects on retinal microvasculature and neuroprotection remain unclear. This study investigates the impact of GLP-1RAs (semaglutide, liraglutide) and GIP/GLP-1-dual agonists (tirzepatide) on ocular blood flow and retinal function in DM patients.
NCT06513026
Individuals with lactase non-persistence (LNP; determined by a functional variant in the LCT gene \[rs4988235, GG genotype\]) are susceptible to lactose intolerance in adulthood due to deficiency of lactase, the enzyme which digests milk lactose sugars. However, many LNP individuals still drink ≥1 cup of milk daily. Recent analysis in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) found that consumption of 1 serving (cup) of milk/day was associated with \~30% lower risk of type 2 diabetes among LNP individuals, but not among individuals with lactase persistence (LP). This beneficial effect might be partially explained by favorable alterations in gut microbiota and related metabolites associated with higher milk consumption among LNP individuals. Based on these observational study findings, the investigator team proposes to conduct a randomized, controlled trial of lactose-containing vs. lactose-free milk in LNP individuals with pre-diabetes, to comprehensively investigate the effects of milk intake on the gut microbiome and glycemic outcomes.
