A Study to Evaluate Intra-arterial Delivery of Mesenchymal Stem Cells for Luminal Ulcerative Colitis Rochester, Minn. Ulcerative Colitis (UC) is a chronic inflammatory disease affecting the mucosal lining of the colon and rectum and the incidence is increasing, but the etiology remains unknown. Patients may require a proctocolectomy due to refractory disease. Prior to an operation, UC is treated with antibiotic therapy, immunomodulatory therapy and immunosuppressive agents. While there is an increasing number of approved biologics for the treatment of UC, there are many patients that still suffer from refractory disease. Thus, alternative mechanisms of therapy are desperately needed. Treatments that have the potential to reduce mucosal inflammation could alleviate the pathology of luminal UC. This trial will use arterially delivered mesenchymal stem cells (MSCs) to produce these regenerative signals allowing for mucosal healing. This study will enroll patients with medically refractory moderate to severe inflammatory UC who are or plan to be scheduled for a colectomy. Patients enrolled will be those who failed all attempts at standard treatment including antibiotics, corticosteroids, immunomodulator, and/or biologic therapy. Participants will undergo screening for study, if eligible, participants will be dosed with 15 million or 30 million cells will be administered via IA delivery with interventional radiology. Participant study visits after study intervention includes visits on: Day 1, Week 1, Week 2, Week 8, Week 24, Week 52, and Week 104. Influence of Diet on Tissue and Body Fluids in Health and Disease Scottsdale/Phoenix, Ariz. This study aims to compare the fatty acid composition of small sample of fat (visceral and subcutaneous) removed at the time of surgery to operative outcomes and the composition calculated from the person’s dietary history and preoperative imaging with MRI/CT scans. This study will also compare the composition of pancreatic fluid collected to that of a sample of fat removed at the time of surgery to drain the collection. Furthermore, we will study the fatty acid composition of drain fluid placed at the time of surgery to that of their fat samples. A Quality of Life Assessment of Patients with Biliary Obstruction Undergoing Endoscopic or Percutaneous Drainage Rochester, Minn., Scottsdale/Phoenix, Ariz., Jacksonville, Fla. The aim of this study is to compare the quality of life of patients with biliary obstruction who have undergone an endoscopic or percutaneous drainage. The quality of life of patients witll be assessed using the validated "European Quality of Life-5 Dimensions Questionnaire" and the "Intervention-Dependent Questionnaire" which was developed according to current literature as well as the expert opinion of gastroeneterologists. Investigating the Link Between Type 2 Immunity and NAFLD in Human Obesity- AIM 1 Scottsdale/Phoenix, Ariz. This study is being done to better understand the relationship between inflammation in your AT, abnormal deposition of fat around your liver and how this affects its appearance and function and ultimately insulin resistance. A Study to Examine Financial Distress in Patients Undergoing Treatment of Locally-advanced Rectal Cancer Scottsdale/Phoenix, Ariz. The purpose of this study is to examine the needs and gap in our understanding of financial burden experienced by rectal cancer patients from a patient perspective to help provide patient centered care and improve psychosocial outcomes of this group. A Study to Evaluate the Prevalence and Impact of Eating Disorders Among Patients with Inflammatory Bowel Disease Jacksonville, Fla. The purpose of this study is to assess the prevalence of eating disorders; specifically, Avoidant/Restrictive Food Intake Disorder (ARFID) among adult patients in the IBD clinic and compare to the patient population seen in the primary care clinics at Mayo Clinic Florida. A Study to Evaluate Ramucirumab Plus Trifluridine/Tipiracil to Treat Patients with Previously-treated Advanced Gastric or Gastro-esophageal Junction Adenocarcinoma Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to compare, in a non-inferiority fashion, the progression-free survival (PFS) in patients with metastatic refractory gastric/Gastroesophageal Junction (GEJ) adenocarcinoma receiving the combination of ramucirumab with TAS-102 vs. paclitaxel and ramucirumab. SOFEED: Six Food vs. One Food Eosinophilic Esophagitis Diet Study Rochester, Minn. The purpose of this interventional study is to test and compare the effectiveness of two elimination diets—the 1-food elimination diet (1FED, milk only) and the 6-food elimination diet (6FED, milk, egg, wheat, soy, tree nut/peanuts, and fish/shellfish). The study will also test the effectiveness of swallowed glucocorticoid therapy in some of the study participants for whom diet therapy was not effective. A Study to Evaluate the Effect of POSE2 on Long-term Gastric Motor Function Rochester, Minn. The purpose of this study is to explore the effectiveness and safety of a modified gastroplication technique for weight loss in five patients with obesity, and includes physiologic appraisal of gastric emptying (via gastric emptying breath test) and post-prandial gastric accommodation (via SPECT). A Study to Establish an Alcoholic Hepatitis Network Rochester, Minn. The purpose of this study is to create a clinical database and bio-repository by obtaining blood, urine, and stool samples (e.g., biological samples) and personal health information from patients to use in future research studies related to alcoholic hepatitis or other diseases.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
