1. A Study to Assess Long-term Symptom Improvement and Recurrence after Operative Management of Popliteal Artery Entrapment Syndrome (PAES)

   Rochester, Minn.

   The purpose of this study is to evaluate long-term symptom resolution and quality of life improvements after operative management of popliyteal artery entrapment syndrome (PAES).

2. Mayo Clinic Upper Digestive Disease Survey

   Rochester, Minn.

   The Mayo Clinic Upper Digestive Disease Survey has been created in order to have a consistent evaluation tools for patients undergoing esophageal reconstruction or treatment  or patients that are experiencing an upper digestive disease in order to standardize and validate outcome measures.  Data will be used to establish the validation of the questionnaires/survey.  Data will also lead to the establishment of “normal” or expected scores for patients undergoing each type of esophagectomy procedure and for upper digestive diseases.  Data will contribute to creating treatment algorithms for symptom management for upper digestive diseases and for post-operative complications and symptoms as well as contribute to pre-operative education.  

3. Stem Cell Coated Fistula Plug in Patients With Crohn's RVF

   Rochester, Minn.

   The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with rectovaginal fistulizing Crohn's disease. Autologous means that these cells that coat the plug come from you. You will be in this study for two years. There is potential to continue to monitor your progress with lifelong regular visits as part of your standard of care. All study visits take place at Mayo Clinic and Rochester, MN. The study visit schedule is as follows: Visit 1 (Week -6) - Screening visit: exam under anesthesia and surgery to assess eligibility of fistula tract, take fat biopsy, if eligible, and fecal diversion. Visit 2 (Week 0; Day 0), exam under anesthesia for stem cell coated fistula plug placement Visit 3 (Week 0; Day 1) Visit 4 (Week 2; Month 1) Visit 5 (Week 4; Month 1) Visit 6 (Week 8; Month 2) Visit 7 (Week 12; Month 3) Visit 8 (Week 24; Month 6) Visit 9 (Week 52; Month 12). Visit 10 (Week 104, Month 24)

4. A Study to Assess Outcomes Based on Different Surgical Approaches to Minimally-invasive Gallbladder Surgery

   Rochester, Minn.

   The purpose of this study is to compare the outcomes of patients who had standard laparoscopic port placement compared to non-standard port placement to determine any difference in occurrence of post-operative hernia and operative complications.

    

    

    

    

5. A Study to Evaluate Wellness Coaching for Caregivers of Thoracic Transplant Candidates

   Rochester, Minn.

   The purpose of this study is to examine the effects of a health coaching intervention on the stress and burden of caregivers of patients awaiting heart or lung transplant.

   Hypotheses:  Caregivers will have traits and behaviors pre-transplant that will predict caregiver readiness, quality of life, and transplant recipient outcomes. Specifically, thoracic pre-transplant caregivers report stress, symptoms of anxiety or depression, and perceive high caregiver burden. These factors may be amenable to pre-transplant intervention to improve overall patient and caregiver outcomes.

   Aims, purpose, or objectives:  We will conduct a pilot trial to test whether caregivers of heart and lung transplant candidates who receive wellness coaching will experience improvement in caregiver-related distress. We will also explore the relationship between caregiving and factors such as uncertainty, resilience, stress level, and affect.

6. Aggressive Malignancy PDX (Avatar) and Cryopreservation Program

   Rochester, Minn.

   The purpose of this study is to assess the ability to successfully create numerous validated patient-derived xenograft (PDX) models from patient tumor specimens obtained at surgery/biopsy via the new Pathology/TRAG cryopreservation protocol, and to generate a large catalog and repertoire of previously unavailable histologically validated PDX.

    

7. A Registry for the Collection and Maintenance of Biological Specimens for Breast Cancer Research

   Rochester, Minn.

   The purpose of this registry is to collect and maintain samples of breast tissue from women and men undergoing surgery for a breast related concern at Mayo Clinic Rochester,  to create a biospecimen resource for the study of benign and cancerous breast conditions.

8. A Study to Compare Somatostatin Analogues with Perioperative Antibiotics versus Prolonged Antibiotics

   Rochester, Minn.

   The purpose of this study is to to determine the individual treatment effect of somatostatin and whether duration of antibiotic therapy coupled with octreotide provides improved outcomes after pancreaticoduodenectomy. 

9. Human Blood and Tissues Repository for Neuroscience Research

   Jacksonville, Fla.

   The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS).

10. A Study of the Drugs Selumetinib Versus Carboplatin/Vincristine in Patients With Neurofibromatosis and Low-Grade Glioma

    Rochester, Minn.

    The pupose of this study is to evaluate whether or not selumetinib works just as well as the standard treatment with carboplatine/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, 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. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.
