  • DECIDE: A Comparative Effectiveness Trial of Metformin Versus Insulin for the Treatment of Gestational Diabetes

    open to eligible females ages 18 years and up

    This is a non-inferiority patient-centered and pragmatic comparative-effectiveness pregnancy randomized controlled trial (RCT) with postpartum maternal and child follow-up through 2 years of 1,572 individuals with gestational diabetes mellitus (GDM) randomized to oral metformin versus injectable insulin. This study will determine if metformin is not inferior to insulin in reducing adverse pregnancy outcomes, is comparably safe for exposed individuals and children, and if patient-reported factors, including facilitators of and barriers to use, differ between metformin and insulin. A total of 1,572 pregnant individuals with GDM who need pharmacotherapy will be recruited at 20 U.S. sites using consistent treatment criteria to metformin versus insulin. Participants and their children will be followed through delivery to two years postpartum.

  • Gauging Outcomes of Total Milk Ingestion on Lipid and gControl

    open to eligible people ages 18 years and up

    Atherosclerotic cardiovascular disease remains the leading cause of death for adults in the United States. The cardiovascular impact of milk consumption remains a matter of long-standing scientific debate. Current guidelines for Americans recommend three daily servings of fat-free or low-fat (1%) dairy over full-fat options due to concerns that saturated fat may increase cardiovascular risk. Yet, the literature does not consistently support non-fat dairy as superior to high-fat dairy for reducing cardiometabolic risk. Identifying the comparative health benefits of non-fat versus high-fat dairy milk would be immediately applicable to patients who seek cardiovascular care. In this randomized, case-crossover trial, the investigators seek to efficiently assess the association between high-fat versus non-fat dairy milk consumption and insulin resistance. Utilizing the Eureka Platform, participants will be randomized to limit their liquid milk consumption to whole milk followed by skim milk (or vice versa), measuring the effect of milk fat content on glycemic index and lipid profile.

  • Glucose Evaluation Through Continuous Glucose Monitors in Polycystic Ovary Syndrome

    open to eligible females ages 18-45

    PCOS is the most common endocrine disorder of reproductive aged women. In addition to menstrual and endocrine abnormalities, PCOS is characterized by insulin resistance and glycemic dysregulation. The pattern of glycemic abnormalities among patients with PCOS may be different than the general population, as evidenced by invasive, time consuming, and costly procedures such as the euglycemic clamp or oral glucose tolerance test. Continuous glucose monitoring (CGM) offers an opportunity to evaluate glycemic status in real world conditions. Furthermore, use of a CGM has been found to improve glycemic status among those with prediabetes and diabetes, but little is known about utility among patients with PCOS. The investigators thus seek to 1) characterize glycemic status using CGM among patients with PCOS and 2) assess the impact of CGM use on metabolic and reproductive health in patients with PCOS.

  • Metabolic and Bio-behavioral Effects of Following Recommendations in the Dietary Guidelines for Americans

    open to eligible females ages 35-64

    This study, at the Western Human Nutrition Research Center (WHNRC), will focus on whether or not achieving and maintaining a healthy body weight is the most important health promoting recommendation of the Dietary Guidelines for Americans (DGA).The investigators hypothesize that improvement in cardiometabolic risk factors resulting from eating a DGA style diet will be greater in people whose energy intake is restricted to result in weight loss compared to those who maintain their weight. The investigators further propose that during a state of energy restriction, a higher nutrient quality diet such as the DGA style diet pattern, will result in greater improvement in cardiometabolic risk factors compared to a typical American diet (TAD) pattern that tends to be lower nutrient quality (more energy-dense and less nutrient-rich.)

  • Metabolic Health Improvement Program: Effects of a Workplace Sugary Beverages Sales Ban and Motivational Counseling

    open to eligible people ages 18 years and up

    The purpose of the study is to test the impact of a multilevel workplace intervention (hospital-wide sales ban on sugar-sweetened beverages (SSBs) and individual-level brief counseling) on employee health.

  • Sodium Bicarbonate and Mitochondrial Energetics in Persons With CKD

    open to eligible people ages 21-85

    Skeletal muscle metabolic health is critical for mobility and an underrecognized target of metabolic acidosis in chronic kidney disease. Impaired muscle mitochondrial metabolism underlies poor physical endurance increasing the risk of mobility disability. The proposed project will use precise in vivo tools to study the pathophysiology of poor physical endurance in a clinical trial treating metabolic acidosis among persons living with chronic kidney disease.

  • Type 1 Diabetes Extension Study

    open to eligible people ages 8-35

    This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: - follow participants to determine how long they continue to produce insulin, and - will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future.

  • Fenretinide Administered in Subjects With Obesity

    Sorry, currently not accepting new patients, but might later

    Many metabolic complications of obesity are a consequence of abnormal responses of the liver, muscle, and fat to insulin actions. Fenretinide may improve the effects of insulin, preventing metabolic complications.

  • GRA in Patients With Type 1

    Sorry, in progress, not accepting new patients

    This study will examine the effects a Glucagon Receptor Antagonist (GRA), has on Insulin Sensitivity, Cardiovascular risks (CVD), and Ketone body formation in participants with Type 1 diabetes. The participants will complete blood tests, tests to measure energy expenditure, CVD risks, and insulin resistance. These tests will be performed prior to start of treatment and again after 12-weeks of treatment with the GRA (called REMD-477).

  • Metformin for the Treatment of Insulin Resistance in Women With Stage I-III Breast Cancer Completing Chemotherapy

    Sorry, not currently recruiting here

    This phase III trial evaluates how often women develop insulin resistance and type-2 diabetes and compares metformin with usual care to usual care alone in treating insulin resistance in women with stage I-III breast cancer after chemotherapy. Insulin resistance occurs when cells stop responding to insulin and is a risk factor for developing diabetes and heart disease. Higher levels of insulin have been shown to be associated with aggressive breast cancer. Metformin hydrochloride decreases the amount of glucose (a type of sugar) released into the bloodstream from the liver and increases the body's use of the glucose. Metformin as well as standard of care diet and exercise education is known to lower blood sugar. However, chemotherapy may accelerate metabolic disorders, such as high blood sugar, and the impact of metformin in these breast cancer survivors is not known. Giving metformin with usual care may be more effective than usual care alone in preventing or reversing insulin resistance in women with stage I-III breast cancer after chemotherapy.

  • Insulin Resistance in HCV Infection

    Sorry, in progress, not accepting new patients

    The study hypothesis is that the means by which HCV induces glucose intolerance is through impairment of B-cell function and compensatory hyperinsulinemia in predisposed Latinos with insulin resistance and that HCV eradication improves these abnormalities. It is also hypothesized that moderate alcohol consumption impact insulin sensitivity and secretion with Latinos with or without HCV infection.

  • Tissue-specific Insulin Resistance in Obstructive Sleep Apnea: Role of Hypoxia

    Sorry, in progress, not accepting new patients

    Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.
