1. Concomitant Renal and Urinary Bladder Allograft Transplantation

   Rochester, Minn.

   Patients that need reconstruction or re-building of their urinary bladder are often limited to having a segment of their intestine used for that purpose. Using intestine is less than ideal as it is an absorptive, mucous producing tissue and placing this in constant contact with urine creates significant long term problems. In patients that require a kidney transplant and bladder reconstruction, this study seeks to use a bladder graft from a deceased donor rather than intestine.

2. Mayo Clinic Cardiovascular Disease Biobank

   Rochester, Minn.

   The purpose of this study is to determine the innate immune, cell death and oxidative stress changes in the myocardium, and aorta of patients with heart failure compared to patients with normal hearts.

3. Trifecta-Lung CfDNA-MMDx Study

   Jacksonville, Fla.

   The purpose of this study is to demonstrate the relationship between dd-cfDNA levels and HLA antibodies in blood transplant recipient and Demonstrate the Molecular Microscope® (MMDx) Diagnostic System results in indication and protocol biopsies from lung transplants.

4. A Study to Develop a Breath Analysis Test

   Jacksonville, Fla.

   The purposes of this study are to establish breath sample collection and analysis techniques, to establish reference ranges for selected clinical populations, and to assess correlations between breath analysis and presence or absence of clinical or pathological evidence of disease.

5. A Study of Study of Immune Tolerance Mechanisms in Kidney Transplant Patients

   Scottsdale/Phoenix, Ariz.

   Hypothesis: we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection. In addition, oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.
   
   Aims, purpose, or objectives:
   1. Investigate the frequency Bregs and their ability to express IL-10 along with other immune cells in the context of tolerance/rejection in kidney transplant patients.
   we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection.
   
   2.Investigate the frequency and functions of Bregs along with other immune cells in the setting of long term corticosteroid use.
   We hypothesize that oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.

6. A Study to Assess Reproductive History in Kidney Donors

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to analyze the effect of parity, menopause and reproductive lifespan on kidney structure and function.

7. A Study to Evaluate Alloantibody Titer in Highly Sensitized Kidney Transplant Candidates

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

   The purpose of this study is to evaluate the utility of using anti-HLA antibody titer to measure the effectiveness of antibody lowering therapy (i.e., desensitization) in highly-sensitized kidney transplant candidates.

    

8. A Study to Evaluate Immune and Hematopoietic Cell Assessment in Clonal B Cell Conditions

   Rochester, Minn.

   The purpose of this study is to evaluate the immune and hematopoietic compartments in patients with monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic leukemia (CLL) in comparison to age-matched healthy control (HC) donors.

9. A Trial of Venoarterial ECMO vs Off-Pump Bilateral Orthotopic Lung Transplantation

   Rochester, Minn., Jacksonville, Fla.

   The purpose of this study is to determine whether off-pump bilateral orthotopic lung transplantation (BOLT) or venoarterial extracorporeal membrane oxygenation (VA ECMO) lung transplantation results in higher PGD grade 3 at 48-72 hours, mortality at 90 days, and the combination of these two endpoints.

   Secondly, to determine whether off-pump or VA ECMO lung transplantation has more red blood cell transfusion (intraoperative plus the first 24 hours in the ICU), chest tube output the first 24 hours, incidence of re-exploration for bleeding, air emboli, stroke, PGD grade 3 at T0 and T24, pneumonia, need for dialysis, rejection, bronchial dehiscence, tracheostomy, length of mechanical ventilation, and hospital length of stay.

10. Immersive Virtual Reality for Reducing Pain and Anxiety in Patients With Temporary Mechanical Circulatory Support Awaiting Heart Transplantation.

    Jacksonville, Fla.

    Patients awaiting heart transplantation on temporary mechanical support often experience pain and anxiety, and their pre-transplant hospital course is often prolonged. We intend to investigate whether an immersive Virtual Reality headset can improve patients pain and anxiety while awaiting cardiac transplantation using specific patient surveys to assess pain, anxiety, and resilience.
