1. A Study to Assess Bone Quality Characteristics, Comparing Type 2 Diabetes Patients who have or have not had Prior Fragile Bone Fractures

   Rochester, Minn.

   The purpose of this study is to assess key characteristics of bone quality, specifically material strength and porosity, in patients who have type 2 diabetes. These patients are at an unexplained increased risk for fractures and there is an urgent need to refine clinical assessment for this risk.

2. Iodine I-131 With or Without Selumetinib in Treating Patients With Recurrent or Metastatic Thyroid Cancer

   Rochester, Minn.

   This randomized phase II trial studies how well iodine I-131works with or without selumetinib in treating patients with thyroid cancer that has returned or has spread from where it started to other places in the body. Many thyroid cancers absorb iodine. Because of this, doctors often give radioactive iodine (iodine I-131) alone to treat thyroid cancer as part of standard practice. It is thought that the more thyroid tumors are able to absorb radioactive iodine, the more likely it is that the radioactive iodine will cause those tumors to shrink. Selumetinib may help radioactive iodine work better in patients whose tumors still absorb radioactive iodine. It is not yet known whether iodine I-131 is more effective with or without selumetinib in treating thyroid cancer.

3. A Study to Test How Muscle Tissue Differs Between People

   Rochester, Minn.

   The purpose of this study is to look for ways to test how muscle tissue differs between people.

4. Insulin Regulation of Lipolysis and Lipolysis Proteins

   Rochester, Minn.

   The purpose of this study is to determine whether impaired insulin-induced suppression of lipolysis (as measured by IC50) is related to lipolysis proteins in groups of volunteers known to vary widely with regards to abdominal adipocyte size and regulation of adipose tissue lipolysis, and whether the improved insulin regulation of lipolysis resulting from treatment with the PPARγ agonist pioglitazone, with or without weight loss, can be linked to specific changes in sets of PPARγ-responsive adipocyte lipolysis proteins in UBO adults.
   
   
   
    

    

    

    

    

5. Study to Determine the Effectiveness of “The Perfect Waist Circumference Measuring Device"

   Rochester, Minn.

   The purpose of this study is to determine whether abdominal subcutaneous and visceral fat measured by diagnostic imaging correlates with waist circumferences measured by the device.

6. A Pilot Study Examining the Effect of Fasting Free Acid and Glucose Concentrations on Insulin Secretion

   Rochester, Minn.

   The purpose of this study is to determine if changes in fasting glucose and FFA concentrations alter 1st phase insulin secretion and proinsulin secretion in non-diabetic and pre-diabetic humans.
    

7. Pediatric Obesity Weight Evaluation Registry (POWER) Study

   Rochester, Minn.

   The main objective of this study is to establish a national pediatric obesity registry known as POWER (Pediatric Obesity Weight Evaluation Registry). This registry will contain clinical data from individual comprehensive pediatric weight management programs around the United States for overweight and obese youth.

8. A Study to Evaluate the Impact of Nutrition Education and Access to Nutritious Foods on Diabetes Control

   Mankato, Minn.

   The purpose of this study is to evaluate whether or not a 6 month supply (1 meal//day) of healthy food choices readily available in the patient's home and self management training including understanding of how foods impact diabetes, improved food choices and how to prepare those foods, improve glucose control.  In addition, it will evaluate whether or not there will be lasting behavior change modification after the program.

9. Shared Decision Making in the Treatment of Obesity Through the Development of an Encounter Tool

   Rochester, Minn.

   The aim of this study is to develop, in close collaboration with stakeholders, an evidence-based decision aid to inform discussions regarding the treatment of obesity (Obesity Choice).

10. A Study to Evaluate the Effect of Metformin on Brain Function in Insulin-resistant Elderly People

    Rochester, Minn.

    The purpose of this study is to determine whether 40 weeks of metformin administration in elderly people (> 60 years) with insulin resistance enhances brain mitochondrial ATP production, to determine the effect of 40 weeks of metformin administration in elderly people (> 60 years) with insulin resistance on blood flow and functional network in different areas of brain, and to determine the effect of 40 weeks of metformin administration in elderly people (> 60 years) with insulin resistance on cognitive function.
