1. Obesity Treatment Outcomes in Liver Transplant Recipients

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to prospectively evaluate the safety and effectiveness of standard of care, individualized, comprehensive weight loss interventions in carefully selected patients with obesity undergoing liver transplant evaluation, including utilization of best lifestyle modifications and guidance to promote a healthy weight, possible medical therapy using FDA-approved weight loss medications and EBMTs with or without concomitant medical therapy.

2. A Study to Evaluate Evacuation Mechanisms Using Advanced Brain Imaging

   Rochester, Minn.

   The objective of this study is to compare the central neural circuitry with fMRI (7T) in 30 asymptomatic healthy controls, 30 constipated patients without DD, and 30 constipated patients with DD at rest (functional connectivity analysis), during rectal distention to desire to defecate and urgency, and during evacuation. 

    

    

    

3. A Study to Develop a Registry for Outcomes and Predictors in Pouch-Related Disorders

   Rochester, Minn.

   The primary purpose of this study is to create a prospective registry of patients with pouch-related conditions to allow for longitudinal assessment of outcomes at 3, 6 and 12 months after a enrollment with a specific diagnosis (acute pouchitis, CADP, CARP, or CD of the pouch).

4. Effect of Cholecystokinin (CCK) on Gastroduodenal Activity in Humans

   Rochester, Minn.

   The purpose of this research study to compare the effects a hormone cholecystokinin (CCK) in the bloodstream in healthy people and in patients with rapid gastric emptying. CCK regulates (controls) the rate at which food empties from the stomach into the small intestine. We want to learn how CCK affects the activity of the stomach and small intestines in patients with rapid gastric emptying. We are also trying to learn if genes regulate the effects of CCK.

5. A Study to Evaluate the Effectiveness of Diaphragmatic Breathing on Reflux Symptoms in Outpatients

   Jacksonville, Fla.

   The purpose of this study is to establish if abdominal breathing exercises can reduce symptoms associated with reflux.

6. A Study to Evaluate the Effects of Tradipitant on Satiation, Gastric Volume, Gastric Accommodation, and Gastric Emptying in Healthy Volunteers

   Rochester, Minn.

   The purpose of this study is to evaluate the effects of tradipitant relative to placebo in healthy volunteers:

   • Difference in fasting GV;
   • Difference in postprandial GV and in accommodation volume (that is, postprandial minus fasting gastric volumes);
   • Difference in gastric emptying (T1/2, emptying at 2h and emptying at 4h);
   • Volume to fullness (sensation of usual postprandial fullness) and maximum feeling of fullness (MTV).

7. A Study to Assess Intestinal Barrier Function and Permeability in Patients with Functional Dyspepsia

   Jacksonville, Fla.

   The purpose of this study is to investigate, using several novel techniques, potential pathophysiologic abnormalities that could lead to the development of symptoms of functional dyspepsia.

8. A Study of Intratumoral Injection of Dendritic Cells after High-Dose Conformal External Beam Radiotherapy in Patients with Unresectable Liver Cancer

   Rochester, Minn.

   Group 1: The primary purpose of this study is to evaluate the safety and tolerability of an autologous dendritic cells (DC) vaccine delivered by intra-tumoral injection in patients with primary liver cancer treated with high-dose conformal external beam radiotherapy (EBRT).

   Group 2: The primary purpose of this study is to estimate the progression-free survival rate at 2 years post-registration to see if treatment is efficacious compared to historical data

9. Mayo Clinic Inflammatory Bowel Disease Repository

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

   The purpose of this research study is to collect clinical information and human samples from patients with IBD. The data collected will be used to create an organized, accessible resource of human samples for biological research in IBD.

10. Symptoms During a Gastric Emptying Study

    Rochester, Minn.

    To understand the utility of measuring stomach emptying, symptoms during a stomach emptying, and blood markers of body metabolism.
