1. 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. 

    

    

    

2. Cancer screening practices of individuals with Lynch Syndrome

   Rochester, Minn.

   This is a survey study to describe how women with Lynch syndrome are being screened for gynecologic cancer risk, their perception of cancer risk, and uptake of risk reducing surgery.

3. Validation of Pediatric Inflammatory Bowel Disease Knowledge Questions (Emma)

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The aim of this study is to test the validity of the current question database in a large cohort of children with Inflammatory Bowel Disease (IBD) in several pediatric gastroenterology centers. 

4. 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.

5. 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.

6. 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.

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 Autologous Dendritic Cells After High-Dose Conformal External Beam Radiotherapy In Patients With Unresectable Liver Cancer

   Rochester, Minn.

   The primary purpose of the pilot 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).

   The primary purpose of the phase II 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. A Study to Evaluate the Therapeutic Effectiveness of Rifaximin in Diabetic Gastroparesis Patients Using Bloating as the Primary Endpoint

   Jacksonville, Fla.

   The primary purpose of this study is to prospectively assess symptoms of bloating (severity, prevalence) in patients with diabetic gastroparesis.

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.
