This study aims to address the following key scientific question by establishing a large-scale, high-standard clinical cohort: the independent contribution of MASLD and its progression to liver fibrosis on cardiovascular outcomes in patients with T2DM, after excluding the confounding effects of traditional cardiovascular risk factors. Its technical value lies in utilizing prospective follow-up data combined with a multivariable competing risks model to develop and validate a cardiovascular risk prediction and early warning system tailored for Chinese populations with T2DM complicated by MASLD. Clinically, the findings will provide interdisciplinary evidence-based support for endocrinology and cardiology, helping clinicians identify high-risk individuals and prevent cardiovascular events through early intervention targeting hepatic metabolic disorders. This has significant implications for reducing overall mortality among diabetic patients in China and alleviating the public health burden.
The Family Investigation of Nephropathy and Diabetes (FIND) is a multicenter study designed to identify genetic determinants of diabetic kidney disease. FIND will be conducted in eleven centers and in many ethnic groups throughout the United States. Two different strategies will be used to localize genes predisposing to kidney disease: a family-based genetic linkage study and a case-control study that utilizes admixture linkage disequilibrium. The center based at the Phoenix office of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK-Phoenix) will conduct family-based linkage studies among American Indian populations in the southwestern United States. Participants (index cases) with diabetes and kidney disease will initially be recruited, and their parents and siblings will also be invited to participate. Genetic material from these participants will be used to genotype markers throughout the genome. Linkage analysis will be conducted to identify particular chromosomal regions containing genes that influence susceptibility to diabetic kidney disease. Linkage analyses will also be used to identify genes influencing traits related to diabetic kidney disease, such as serum creatinine, urinary protein excretion, plasma glucose levels, blood pressure and blood lipid levels. Regions that show evidence for linkage will then be examined in more detail, with both genetic linkage and association studies, to attempt to identify the specific genes that influence diabetic kidney disease, or related traits. The identification of genes that influence susceptibility to diabetic kidney disease will lead to a better understanding of how kidney disease develops. In the long run, this may lead to improved treatment and prevention of diabetic kidney disease....

In current clinical practice, both single-session and multiple-session PRP approaches are widely accepted and utilized. The purpose of this study is to compare the safety and effectiveness of single-session and multiple-session PRP.
The QUebec Adipose and Lifestyle InvesTigation in Youth (QUALITY) Cohort study is a unique and comprehensive longitudinal study of 630 Caucasian children and their parents that was designed to investigate the natural history and determinants of childhood obesity and its cardiometabolic consequences.
The purpose of this research study is to determine how gastric bypass surgery effects metabolism in obesity and Type 2 Diabetes. One mechanism that has been investigated in animal models is change to the biology of the small intestine (Roux limb) and how glucose and other fuels are metabolized (or how the body digests and uses sugar and other fuels). This study will evaluate the role of the intestine in the beneficial metabolic effects of gastric bypass surgery. It specifically will examine whether the intestine increases its metabolism and its activity, and whether this results in an increase in fuel utilization. Thirty two (32) subjects will be recruited (18 with and 14 without Type 2 Diabetes). At the time of gastric bypass surgery, a small piece of intestine that is usually discarded will be collected. At three time points over the first year after surgery, intestinal samples will be obtained by endoscopy or insertion of a lighted flexible tube through the mouth. Blood samples will be taken at all time points, as well. All samples will undergo comprehensive metabolic analyses. Comparisons will be made between the two groups to understand the metabolic changes over time and if there are differences between the two groups.
The goal of this clinical investigation is to explore a non-invasive technology for measuring the microcirculatory structure, composition and function in patients from a primary care population. The main aims are: 1. To evaluate the robustness of the technology for assessment of the molecular composition and structure of the skin tissue and microcirculatory function, on a prospective primary care population. 2. To evaluate the device and method on its capability to detect deficiencies in circulation, compared with existing reference systems with similar characteristics for patients with known cardiovascular disease risk and/or diabetes.
This study is testing whether a new medication called CX11 works and is safe for participants with type 2 diabetes who have not reached good blood sugar control while taking a steady dose of metformin, with or without a steady dose of an SGLT2 inhibitor, for at least 90 days. The study is being done at multiple medical centers. Participants are assigned by chance (randomized) to different groups, and neither the participants nor the study staff know which group they're in (double-blind). The groups are compared side by side (parallel), and some participants will receive inactive pills (placebo) to help measure the true effect of the study drug. After screening, participants will be randomly placed into one of six groups, with equal chances of being in any group. Each group will receive a different dose of CX11 or a placebo. Treatment will last 24 weeks. After that, all participants will have a 2-week follow-up period to check on safety.
In this preliminary observation study, the investigators will assess muscle function in terms of muscle strength and leverage imaging (MRI) and spectroscopy (31P-MRS) based techniques to assess longitudinal changes in muscle volume, quality and metabolic function in patients with T2D and obesity prescribed to semaglutide therapy. The patients will be evaluated at three time points: 1) baseline, 2) 3-month and 3) 6-month after the therapy. These longitudinal changes will then be compared and correlated with changes in physical measurements such as BMI and patient reported outcome measures (PROMs). The primary aim of our study is to investigate the longitudinal effects of semaglutide therapy on patients with T2D and obesity, on skeletal muscle strength, muscle volume, quality and metabolic function.
The goal of this clinical trial is to learn if SGLT2 inhibitor Henggliflozin works to improve glucose variability in type 2 diabetes and if Henggliflozin can benefit immunosenescence. The main questions it aims to answer are: Does Henggliflozin as an add on treatment works to improve blood glucose fluctuation in type 2 diabetes? Does Henggliflozin has extra benefits like improve immunosenescence beyond hypoglycemic effects? Researchers will compare Henggliflozin to a placebo to see if Henggliflozin can improve glucose variability and immunosenescence. Participants will: Take Henggliflozin or a placebo every day for 16 weeks. Receive weekly follow-up calls to guide them in adjusting their insulin doses. Return for an on-site visit at 4 weeks and 16 weeks. Take a continuous glucose monitoring (CGM) for 7 days at the Visit 1 and at the end of the study.
The purpose of this study protocol is to assess the effect of concurrent aerobic and resistance training in patients with type 2 diabetes on vitamin D treatment
The prevalence of cognitive dysfunction in diabetic patients is high, which seriously affects the quality of life of patients, and early intervention is of great significance. Central nervous system insulin resistance plays a key role in the pathogenesis of cognitive dysfunction in diabetic patients. Central insulin resistance observed by functional magnetic resonance imaging (fMRI), may serve as an alternative endpoint for assessing cognitive function. Sodium glucose cotransporter 2 inhibitor (SGLT2i) may improve cognitive impairment by improving central insulin resistance.

The primary objective is to assess the safety profile through monitoring adverse events. Secondary objectives include evaluating weight loss, metabolic parameters improvement, and treatment satisfaction in real-world clinical practice.
Nutrition is very important to keep blood sugar levels balanced. If blood sugar levels are too high, it can lead to diseases such as cardiovascular disease and type 2 diabetes (T2DM). Therefore, adjusting what one eats, also called a diet or nutritional intervention, can help prevent these diseases. However, not everyone responds the same to a diet. In about 30% of people, a diet does not work as hoped. This can be due to various reasons, such as a person's metabolism, genetic predisposition, the composition of the food one eats, or the bacteria in the intestines. Everyday things like sleep, stress, and movement also play a role. The investigators used a computer model to classify people with overweight and obesity into groups based on these factors. The investigators call such a group a 'Metabolic Phenotype', or in short 'Metabotype'. Based on the Metabotype, a personalised diet was developed (personalised nutrition intervention) that may better suit each person's unique situation. The investigators hypothesize that a precision nutrition intervention, tailored to Metabotypes identified through unsupervised clustering (using the aforementioned computer model) of predefined, accurate features related to cardiometabolic health-specifically, tissue-specific glucose and lipid metabolism and detailed body composition-will enhance blood glucose homeostasis, reduce cardiometabolic risk, and improve adherence to the intervention and mental well-being, compared to population-based dietary guidelines. The present project will contribute to targeted and efficient precision-based dietary strategies for individuals at increased risk of T2DM.
This study aims to screen and diagnose coeliac disease in patients with type 2 diabetes and monitor the effect of gluten-free diet on the metabolic status
The goal of this randomized controlled trial is to compare the efficacy and safety of the iLet Bionic Pancreas (BP) System in adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes) compared to standard of care when ordered by primary care providers. The main question it aims to answer is: Can the iLet BP by deployed in primary care settings to adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes)? Researchers will compare 13-weeks of iLet BP use to routine care to see if iLet BP use has a greater reduction in HbA1c compared to13-weeks of routine care. Participants will: Use the iLet BP for 13-weeks or continue their routine care Be trained to use the study devices or continue their routine care Complete a virtual screening visit, mid-period follow up calls and a final visit Complete baseline CGM collection Complete surveys and fingerstick a1c blood tests Routine care participants will have the option to complete an observational extension phase where they will wear the iLet BP for 13-weeks
The ENDOCARE-SCREEN study is a single-center, observational, cross-sectional screening study designed to assess the prevalence, phenotypes, and determinants of metabolic dysfunction-associated steatotic liver disease (MASLD/MAFLD) in adults with components of metabolic syndrome. Up to 10,000 participants aged ≥18 years with overweight, obesity, or metabolic risk factors will undergo standardized screening including a health questionnaire, anthropometric measurements, blood pressure assessment, laboratory testing, and liver ultrasound. The study aims to generate a comprehensive metabolic-hepatic dataset integrating clinical, laboratory, imaging, and lifestyle data. Collected data will be used to identify metabolic and behavioral risk factors for MASLD, characterize disease phenotypes, and support the development of predictive models. The ENDOCARE-SCREEN study will also serve as a qualification platform for selecting eligible participants for a subsequent interventional randomized controlled trial (ENDOCARE-SUPPORT). The study involves minimal risk procedures routinely used in clinical practice and follows ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines.
This study will include a type 1 hybrid effectiveness implementation study to evaluate the effectiveness of the PROMOTE (peer support plus remote patient monitoring) program among Black adults with uncontrolled type 2 diabetes recruited from local primary care practices in Jefferson County, Alabama. Additionally, a mixed methods evaluation to characterize the contextual factors relevant to implementation of PROMOTE using Practical Robust Implementation Science Model (PRISM) will be conducted.

The Cohort on Plant-based Diets (COPLANT) study is a multi-centre cohort study that starts baseline recruitment from 2024 to 2027 with approximately 6,000 participants in Germany and Austria. The COPLANT study focuses on vegan (no animal products), vegetarian (no meat and fish, but dairy products and eggs), pescetarian (no meat, but fish) and omnivorous (mixed diet including all possible animal products) diets. The aim of the COPLANT study is to gain new insights on health benefits and risks as well as social, ecological and economic effects of different plant-based diets in comparison to a mixed diet. In addition to a detailed dietary survey using an app adapted to the needs of this study, the baseline examination includes measurements of body composition, bone health, cardiovascular risk factors, diabetes risk, contaminants and lifestyle. For the basic laboratory program, fasting blood, 24-hour urine collection and a stool sample are taken from all study participants. Furthermore, specific aspects of dietary behavior, physical activity and other lifestyle factors are collected via questionnaires. Follow-up studies are planned at intervals of 5, 10 and 20 years after the baseline visit.
