1. A Study to Examine the Molecular Mechanisms of Acute Effects of Resistance Exercise

   Rochester, Minn.

   The purpose of this study is to seek and identify the mechanistic underpinnings of the effects of resistance exercise (RE) on insulin sensitivity.

2. Pediatric Home Tube Feeding, the Impact of Nutrition Intervention Prior to Tube Placement

   Rochester, Minn.

   The purpose of this study is to determine if providing nutrition education and intervention prior to feeding tube placement will increase patient and caregiver satisfaction and improve safety due to consistent education.

    

3. Multi-center Trial in Adult and Pediatric Patients With Type 1 Diabetes Using Hybrid Closed Loop System at Home

   Rochester, Minn.

   The purpose of this study is to demonstrate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP)

4. A Study of the Impact of the Terminology Used to Identify Papillary Thyroid Cancer on the Treatment Options Chosen by Patients

   Rochester, Minn.

   The purpose of this study is to explore how using different terms (with or without the word cancer) to identify papillary thyroid cancer might affect the decisions patients would make about treatment.

5. A Study to Evaluate the Performance of an Advanced Algorithm with CGM in Adults, Adolescents, and Pediatrics

   Rochester, Minn.

   The purpose of this study is to demonstrate the performance of the Guardian™ Sensor (3) with an advanced algorithm in subjects age 2 - 80 years, for the span of 170 hours (7 days).

6. A Study to Analyze Gender Congruence After Gender Confirmation Surgery

   Rochester, Minn.

   The purpose of this study is to assess the success and effectiveness of gender confirmation surgeries on eliminating gender incongruence and improving life satisfaction, and compare patient’s status with the preoperative results.

7. A Study Evaluating the Prevalence, Incidence and Predictors for Development of the Impulse Control Disorders in Patients with Prolactinomas Treated with Dopamine Agonist Therapy

   Rochester, Minn., Jacksonville, Fla.

   The purpose of this study is to establish incidence and prevalence of Impulse Control Disorders (ICDs) in patients with prolactinomas treated with dopamine agonists (DA), to determine the predictors of ICD development, and to establish a predictor scoring system that could be subsequently validated and applied prior to initiation of DA.

8. A Study of Bone Microstructure and Bone Strength Using High-Resolution CT Scanning in Adults with Repeat Fractures

   Rochester, Minn.

   The purpose of this study is to obtain more detailed information about bone structure in adults with repeat bone fractures.

    

9. A Study to Evaluate the Effect of Improving Glycemic Control on Gastric Emptying in Type 1 and Type 2 Diabetes Mellitus

   Rochester, Minn.

   The purpose of this study is to evaluate the effects of improving glycemic control, and/or reducing glycemic variability on gastric emptying, intestinal barrier function, autonomic nerve functions, and epigenetic changes in subjects with type 1 diabetes mellitus (T1DM) and  type 2 diabetes mellitus (T2DM) who are switched to intensive insulin therapy as part of clinical practice.

10. Effects of Niacin on Intramyocellular Fatty Acid Trafficking in Upper Body Obesity and Type 2 Diabetes Mellitus

    Rochester, Minn.

    Muscle insulin resistance is a hallmark of upper body obesity (UBO) and Type 2 diabetes (T2DM). It is unknown whether muscle free fatty acid (FFA) availability or intramyocellular fatty acid trafficking is responsible for the abnormal response to insulin. Likewise, we do not understand to what extent the incorporation of FFA into ceramides or diacylglycerols (DG) affect insulin signaling and muscle glucose uptake. We will measure muscle FFA storage into intramyocellular triglyceride, intramyocellular fatty acid trafficking, activation of the insulin signaling pathway and glucose disposal rates under both saline control (high overnight FFA) and after an overnight infusion of intravenous niacin (lower/normal FFA) to provide the first integrated examination of the interaction between FFA and muscle insulin action from the whole body to the cellular/molecular level. By identifying which steps in the insulin signaling pathway are most affected, we will determine the site-specific effect of ceramides and/or DG on different degrees of insulin resistance.
    Hypothesis 1: Greater trafficking of plasma FFA into intramyocellular DG will impair proximal insulin signaling and reduce muscle glucose uptake.
    Hypothesis 2: Lowering FFA in UBO and T2DM by using an intravenous infusion of niacin will alter trafficking of plasma FFA into intramyocellular ceramides in a way that will improve insulin signaling and increase muscle glucose uptake.
    Hypothesis 3: Lowering FFA in UBO and T2DM by using an intravenous infusion of niacin will alter trafficking of plasma FFA into intramyocellular DG in a way that will improve insulin signaling and increase muscle glucose uptake.
