1. 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.

2. 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.
   
   
   
    

    

    

    

    

3. Comparing Capecitabine and Temozolomide in Combination to Lutetium Lu 177 Dotatate in Patients With Advanced Pancreatic Neuroendocrine Tumors

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare capecitabine and temozolomide to lutetium Lu 177 dotatate for the treatment of pancreatic neuroendocrine tumors that have spread to other parts of the body (advanced) or are not able to be removed by surgery (unresectable). Chemotherapy drugs, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. The purpose of this study is to find out whether capecitabine and temozolomide or lutetium Lu 177 dotatate may kill more tumor cells in patients with advanced pancreatic neuroendocrine tumors.

4. 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.

5. A Study to Evaluate Innovative Application for Personalized Diabetes Care

   Scottsdale/Phoenix, Ariz.

   The multi-purpose of this study is to examine the effectiveness of “InsulisiteGuider” in patients with type 1 diabetes (T1D) through a two-group randomized controlled trial, to characterize the RNA biomarkers in skin epithelial cells isolated from the continuous subcutaneous insulin infusion (CSII) cannulas from T1D patients, and to characterize RNA biomarkers in the blood and saliva of TID patients.

    

6. A Study to Evaluate Molecular Mechanisms of Exercise Benefits in Insulin Resistant People

   Rochester, Minn.

   The aim of the study is to investigate the effects of a 3-month resistance exercise program (in people aged 50 to 75) on muscle mass, body composition, muscle strength, brain function and cognition, muscle efficiency processing blood sugar, the body’s ability to build muscle, and fat cells.

   Earlier research has shown that exercise has significant benefits in preventing certain diseases and conditions such as diabetes, dementia, heart disease, and more. We also know from other research that resistance exercise (lifting weights) and aerobic exercise (running, biking, walking), improve metabolism through separate ways on the molecular level, also called “molecular pathways.” With new and sophisticated technologies, we can analyze these molecular pathways to learn how exercise improves health. 

   The purpose of the study is to understand why resistance exercise can prevent disease though analyzing the ‘molecular pathways’ in correlation with blood sugar to understand its effects on diabetes. We also will correlate these results with brain scan and cognitive tests to understand the mechanisms behind cognitive decline and dementia. 

   Participants in this study will undergo a series of baseline measurements including but not limited to blood tests, brain scans, aerobic exercise tests, body composition scans, resistance exercise, a 24-hour research visit, 4 needle muscle biopsies, 2 needle fat biopsies, and an infusion of amino acids (the building blocks of muscles). 

   Following the completion of the baseline visits, participants will be randomly placed into a resistance training group or a control group. 
   1.    Resistance Training Group: Participants put into the resistance training program will take part in a personalized resistance training program and meet with a personal trainer four times a week for three months. Following the three months of resistance training participants will repeat the baseline visits and will be completed with the study. 
   2.    Control Group: Participants put into the control group are asked not to make any lifestyle changes for 3 months. Following the 3 months, they will come back for a repeat of the baseline measurements. At this point they will have the choice to take part in the resistance training program, followed by a third set of baseline measurements.

7. A Study to Evaluate the Effects of Ondansetron on Gastrointestinal Sensorimotor Dysfunctions in Diabetes Mellitus and Dyspepsia

   Rochester, Minn.

   The purpose of this study is to understand why patients with indigestion, with or without diabetes, have gastrointestinal symptoms and, in particular, to understand where the symptoms are related to increased sensitivity to nutrients.Subsequently, look at the effects of Ondansetron on these patients' symptoms.

8. A Study to Establish an Obesity-Related Phenotype Registry

   Rochester, Minn.

   The purpose of this study is to create a registry of obese patients who have been phenotyped to understand the heterogeneity of obesity.

9. Testing Lutetium Lu 177 Dotatate in Patients With Somatostatin Receptor Positive Advanced Bronchial Neuroendocrine Tumors

   Rochester, Minn.

   The purpose of this trial is to study the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

10. Recovery from Cushing syndrome and Mild Autonomous Cortisol Secretion

    Rochester, Minn.

    The primary purpose of this study is to determine pre-surgical and post-surgical predictors of the duration and severity of glucocorticoid withdrawal in patients undergoing a curative surgery for cortisol excess.
