Diabetes Prevention AI: Enhancing Prevention Strategies Using Personalized Nutrition and Fitness Coaching for the Next Generation

This study is testing an artificial intelligence (AI) chatbot designed to help adults at risk for type 2 diabetes adopt healthier lifestyles. The chatbot provides personalized and culturally tailored guidance on nutrition, physical activity, resistance training, and goal setting. About 30 adults aged 18 to 55 years will use the chatbot for 6 weeks and provide feedback through surveys and interviews. Researchers will evaluate whether the chatbot is easy to use, helpful, and trustworthy, and whether data about changes in health behaviors can be feasibly collected, in order to inform larger future studies to improve diabetes prevention.

Characteristics of NAFLD Among Type 2 Diabetes Patients

Type 2 diabetes patients have a high risk of developing NAFLD. This was confirmed during previous research, a high prevalence of NAFLD among type 2 diabetes mellitus patients was found. The investigators want to determine the characteristics of this population.

Assessing the Effects of a Buckwheat Beverage on Postprandial Glucose Metabolism on Healthy and T2D Individuals

Buckwheat is a unique crop because is naturally rich in compounds that have shown beneficial effects on glucose metabolism. A constant high glucose level in blood after meal consumption is an independent risk factor for cardiovascular complications and death. In order to prevent Type 2 Diabetes Mellitus (T2D) and/or its complications it is important to have a strict control of the blood glucose levels after a meal. There are known therapies for the control of the high glucose blood levels such as agents that act on intestinal digestion of carbohydrates and therapeutic agents that mimic the insulin response after a meal. The combination of these type of agents was commonly prescribed in the treatment of T2D. The aim of the study is to assess the effect of a buckwheat beverage on postprandial glucose metabolism in healthy individuals and those with T2D controlled by medication and diet.

Comparative Effectiveness and Safety of Four Second Line Pharmacological Strategies in Type 2 Diabetes Study

To perform an observational analysis to emulate a target trial (i.e., a hypothetical pragmatic trial that would have answered the causal question of interest) comparing the effectiveness and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide 1 receptor agonists (GLP-1RA), dipeptidyl peptidase-4 inhibitors (DPP-4i), and sulfonylureas (SU), at the class and individual agent level, in head-to-head comparisons in patients with type 2 diabetes (T2D).

Effect of Exercise and/or Liraglutide on Vascular Dysfunction and Insulin Sensitivity in Type 2 Diabetes ( ZQL007)

The primary objective of this study is to examine whether exercise training alone, liraglutide treatment alone or exercise training plus liraglutide treatment increases cardiac and muscle capillary blood volume, improves vascular function in the larger conduit vessels, and enhances insulin's metabolic action in humans with Type 2 diabetes. Subjects will be randomized to one of the three groups: exercise training, liraglutide treatment, and exercise + liraglutide. They will be studied at the baseline and then after 16 weeks of intervention.

Cardiovascular Outcomes in Bariatric Surgery Patients With Type 2 Diabetes

The objective of the analysis was to evaluate the relationship between bariatric surgery and cardiovascular outcomes in obese patients with type 2 diabetes.

Uric Acid Lowering Trial in Youth Onset T2D

Adolescents and young adults with youth-onset type 2 diabetes (T2D) are disproportionally impacted by hyperuricemia compared to non-diabetic peers and youth with type 1 diabetes (T1D). In fact, 50% of males with youth-onset T2D have serum uric acid (SUA) greater than 6.8 mg/dl. The investigators also recently demonstrated that higher SUA conferred greater odds of developing hypertension and diabetic kidney disease (DKD) in youth with T2D over 7 years follow-up. Elevated SUA is thought to lead to cardiovascular disease (CVD) and DKD by inflammation, mitochondrial dysfunction and deleterious effects on nephron mass. While there are studies demonstrating beneficial effects of uric acid (UA) lowering on vascular health in the general population, there are no studies in youth-onset T2D. Youth-onset T2D carries a greater risk of DKD and CVD compared to adult-onset T2D and T1D. Accordingly, a clinical trial evaluating UA lowering therapies is needed in youth-onset T2D. Krystexxa (pegloticase), a uricase, effectively lowers SUA and therefore holds promise as a novel therapy to impede the development of CVD and DKD in youth-onset T2D. This proposal describes a pilot and feasibility trial evaluating the effect of UA lowering by pegloticase on markers of CVD and DKD in ten (n=10) youth aged 18-25 with youth-onset T2D (diagnosed \<21 years of age) over 7 days. The overarching hypothesis is that pegloticase improves marker of cardiorenal health by lowering UA.

Reducing Metabolic Dysregulation in Obese Latina Breast Cancer Survivors Using Physical Activity

This study is about testing whether exercise will improve fitness and lessen risk factors related to heart disease, diabetes, and obesity in Latina breast cancer survivors.

Dietary Approaches to Stop Hypertension for Diabetes

The objective of the DASH4D trial is to determine the effects, alone and combined, of (a) the DASH4D diet (a DASH-style diet modified for people with diabetes) vs. comparison diet that is typical of what many Americans with diabetes eat and (b) lower sodium intake vs. higher sodium intake on blood pressure (BP). The core design is a single-site, 4-period, crossover feeding study with 5-week periods. Participants are fed each of four isocaloric diets, presented in random order. The primary contrast of interest is DASH4D diet with lower sodium vs. comparison diet with higher sodium.

Psychosocial, Environmental, and Chronic Disease Trends in Puerto Rico

The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic disease Trends', an island-wide, longitudinal population cohort of 2,500 adults (30-75 years) in PR recruited with a community-wide sampling strategy, and assessed in a network of several partner clinics across the island. The study will collect comprehensive data on multiple psychosocial, dietary, and food-related factors, CVD biological markers, and medical record data, with follow-up at 2-years, and will assess variations by urban-rural area and by timing before-after Maria.

The Effects of Evolocumab in Patients With Diabetes and Atherosclerotic Vascular Disease

Experimental models have linked lipid lowering therapies with systemic inflammation; however, relatively little is known about this network in clinical populations and specifically how it changes with PCSK9 inhibition. The eligible subjects will have 6 visits in 13 to 16 weeks and will have Repatha/placebo 140mg subcutaneous every 4 weeks for 3 times since randomization visit, blood tests will be done in each visit to evaluate the effects of evolocumab upon biocellular markers potentially altered by PCSK9 inhibition in a population of type 2 diabetes patients with microvascular dysfunction. Primary Aims: Determine the ACUTE and SHORT-TERM effects of PCSK9 inhibition with evolocumab on biocellular markers of inflammation, immune mediated thrombosis and rheology. The data from this trial will be used to support a clinical trial to assess the role of PCSK9 inhibition in type 2 diabetes patients with cardiac microvascular dysfunction. Secondary Aims: 1. To define the association between PCSK 9 concentrations and immune-related phenotype. 2. To define the association between Lp(a) concentrations, oxidized phospholipids (OxPL), ApoB, biocellular markers of inflammation, tissue factor and immunothrombosis.

Influence of Preprandial Metformin Administration on Carbohydrate Absorption

Type 2 diabetes is spreading worldwide as well as obesity. Metformin is the most prescribed antidiabetic medication. One suggested mechanism of action is by decreasing carbohydrate absorption. It is usually recommended to take metformin during the meal to decrease gastrointestinal side effects. However, if metformin decreases carbohydrate absorption, this might not be the most efficient intake. To study the influence of preprandial metformin administration on carbohydrate absorption, it will repeat 3 oral glucose tolerance test on obese dysglycemic patients, without metformin or with metformin administer 30 or 60 minutes before. We will also evaluate how it impacts gastrointestinal tolerance.

Dapagliflozin Effect on Glucose Variability in Patients Post Bariatric Surgery

This study evaluates the effect of SGLT-2 inhibitors (dapagliflozin) on the blood glucose excursions by a continuous glucose monitoring system, the incidence of hypoglycemia and hyperglycemia and change in glycated hemoglobin (HbA1c) level in people had bariatric surgery with and without type 2 diabetes.

SGLT2 Inhibitors, Ketones, and Cardiovascular Benefit Research Plan

The study team will examine the effects of SGLT2i (and SGLT2i-induced increases in plasma ketone concentrations) on skeletal muscle and cardiac ketone uptake, skeletal muscle bioenergetics, cardiopulmonary exercise capacity, and patient-reported functional outcomes.

Intensive Diet and Physical Activity on Diabetes

It is a multicenter, open-label, parallel-group, randomized controlled clinical trial, which is designed to enroll newly diagnosed type 2 diabetes patients with overweight or obesity. The patients are randomized to an intensive diet intervention (intermittent very-low -calorie diet), enhanced physical activity intervention (high-intensity interval training exercise prescription combined with resistance training) or standard education group (diabetes health education only, including lifestyle education and guidance) for 12 weeks. This trial will test the primary hypothesis of whether an intensive lifestyle treatment (diet or physical activity) is more effective than a standard education in glycemic control. The secondary hypotheses are to compare the intensive lifestyle treatment with a standard education on adipose distribution, metabolic parameters, metabolic molecules, Framingham Risk Scores, and quality of life, et al.

A Causative Role for Amylin in Diabetic Peripheral Neuropathy

Three pieces of information lead to the basis for this study: 1. Individuals with Type-2 diabetes commonly develop peripheral neuropathy. 2. Increased production of the hormone amylin occurs in individuals who have Type-2 diabetes. 3. Aggregations of amylin was found in the peripheral vasculature of rats that overexpressed human amylin. The purpose of this study is to determine whether a correlation exists between the amount of amylin present in the upper extremities of human subjects with Type-2 diabetes and the extent to which symptoms of peripheral neuropathy are expressed in those subjects. The investigators will be testing this by initially collecting blood and skin biopsy samples from subjects, followed by measuring patient sensation and pain responses to heat, cold, and pressure in the upper extremities.

Effects of Sitagliptin in Individuals With Genetically Decreased DPP4

This is a pilot clinical trial to test the hypothesis that during sitagliptin (DPP4 inhibitor), individuals heterozygous for DPP4 loss of function variants will have a reduction in DPP4 activity and antigen, lower glucose after a mixed meal, and higher levels of intact DPP4 substrates compared to during placebo and compared to matched controls.

Brain Health in Youth With Normal Weight, Overweight and Obesity at Risk for Type 2 Diabetes (T2D)

Investigators propose to study youth across the spectrum of body mass index (BMI) and dysglycemia. This approach will allow investigators to disentangle the relationship of key features of type 2 diabetes (T2D) risk (e.g. obesity) with intermediary physiologic changes (e.g. insulin resistance, inflammation, β-cell dysfunction and dysglycemia) that pose a risk for the brain. Investigators will determine which of these factors are most associated with differences in brain structure and function among groups, over time, and how these effects differ from normal neurodevelopment.

UK Imaging Diabetes Study Seeing Diabetes Clearly

Prospective, observational cohort study to cross-sectionally assess the health of multiple organs, using multiparametric abdominal magnetic resonance imaging (MRI) scan, and understand if resulting MRI metrics can predict future clinical events over a period of 5 years, in adult patients with type 2 diabetes lacking history of cardiovascular disease.

Small Bowel Diversion

In an effort to replicate metabolic surgery's durable results in metabolic disease while minimizing its risks, two innovative methods has been created. Two surgical methods to create a bowel-to-bowel anastomosis, similar to the type used in current metabolic surgeries. It be to create a jejuno-ileal, side-to-side anastomosis and jejunocolic side-to-side anastomosis. The side-to-side jejuno-ileal anastomosis and side-to-side jejunocolic anastomosis provides two routes for ingested food. The new, shorter route has a malabsorptive effect similar to that seen in Roux en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) - procedures which leads to weight loss. Additionally, delivery of non-absorbed macronutrients to the distal ileum, or transverse colon can enhance incretin effect and improve Type 2 Diabetes Mellitus parameters. However, the native route is also preserved, which theoretically reduces the risk of malnutrition, diarrhea, and metabolic derangements seen in other metabolic surgeries.The side-to-side jejuno-ileal anastomosis was already tested in the Pilot Study of the GI Windows Self-Forming Magnetic (SFM) Anastomosis Device for Creation of an Incisionless Small Bowel Bypass for Treatment of Obesity and Diabetes in year 2015 (15). The results of this study demonstrated the safety of this approach without serious adverse events. This non-surgical approach resulted in significant weight loss, favorable changes in insulin and incretin responses to a mixed meal and significant improvement in HbA1c in T2DM (16).In summary, metabolic diseases are a growing pandemic with suboptimal clinical solutions. The surgical side-to-side jejuno-ileal anastomosis and side-to-side jejuno-colic anastomosis without gastrectomy potentially represents a new class of therapy that may produce durable clinical results generally associated with surgery while minimizing its attendant risks.
