1. 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.

2. Umbilical Cord Blood Collection and Processing for Severe Congenital Heart Disease

   Rochester, Minn.

   Congenital heart disease (CHD) is an abnormal formation that occurs during the development of a baby’s heart, heart valves and/or large vessels such as the aorta artery. CHD is the most common cause of major congenital defects accounting for almost 30% of all defects (Van der Linde D, JACC 2011). While the statistics vary among studies, the best birth prevalence estimate is 8 per 1000 live births (Bernier PL 2010). In the USA, CHD affects 1% of all births per year (Krasuki & Bashore 2016), with an estimated 40,000 babies born with any type of heart defect every year (Benjamin Emelia 2018).  Twenty-five percentof these are affected by a severe congenital heart defect (https://www.cdc.gov/ncbddd/heartdefects/data.html#References). Children with CHD who survive after the surgical procedures can develop heart failure and require a heart transplant at any time in their lives. Infants born with CHD need immediate medical attention and multiple follow-ups throughout their lives. Besides the social and economic impact of CHD on the individual and family lives, CHD treatment places a significant financial burden on the healthcare system. Simeone et al, (2014) reported that the cost of CHD hospitalization in the US was approximately $5.6 billion in 2019, accounting for 15.1% of the total cost for all pediatric hospitalizations in that year.

   The important improvements in CHD diagnosis and surgical treatment in the last decades has led to an increased survival of newborns affected with heart defects. A large number of CHD can be diagnosed during pregnancy, and the patients can present a broad range of symptoms. Forms of CHD are usually classified based on their severity, from mild to severe. One of the mildest forms of CHD is atrial septal defect, which can be undetectable until adulthood (Hoffman & Kaplan, 2002) and VSD (Penny DJ, 2011). On the other hand, severe CHD that requires multiple palliative surgeries includes single ventricle defects, such as hypoplastic left heart syndrome (HLHS) and tricuspid atresia.

   The survival of infants with CHD will depend on the severity of the defect and the time of diagnosis and treatment received. The one-year survival of newborns with severe or critical CHD (generally any type of surgery/procedures in their first year of life) is estimated to be 75%.

   Stem cell therapy has emerged as a new paradigm of treatment in the field of CHD with promising results. Cardiac regeneration has been the focus of acquired, adult heart disease for many years. However, congenital heart disease with structural abnormalities may also be a good target for other research studies. In fact, the pediatric heart is naturally growing and may be amendable to regenerative strategies. Furthermore, the initial pre-clinical and clinical studies have demonstrated that the delivery of stem cells into the heart of patients with CHD is feasible and safe. Moreover, the cell therapy approach, along with the standard surgical palliation, seems to offer benefits over surgical treatment alone. Even though the number of cell therapy clinical trials for CHD has increased in the last decade, more long-term follow-up studies are needed in this population setting in order to define the role of stem cell therapy in the clinical practice. Therefore, confirming our ability to produce autologous cells (cells from the patient's own body) from patients with severe CHD is an important step towards the long-term goal of being able to discover innovative cell-based protocols.

3. A Study to Collect Clinical Outcomes of Anatomic and Reverse Total Shoulder Arthroplasty

   Scottsdale/Phoenix, Ariz.

   The purpose of the study is a multi-center prospective registry to collect clinical outcomes of anatomic and reverse total shoulder arthroplasty.

4. Allogeneic Mesenchymal Stromal Cell Donor Bank

   Rochester, Minn.

   The purpose of this study is to collect adipose tissue from patients undergoing elective surgery, or from healthy volunteers, test the donors to assure that they comply with all regulatory aspects required of healthy donors, expand and test mesenchymal stromal cells (MSC), and bank them for future use.

5. MelmarT Melanoma Margins Trial Investigating 1cm v 2cm Wide Excision Margins for Primary Cutaneous Melanoma (MelMarT)

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to determine differences in the rate of local recurrence and melanoma specific survival. A reduction in margins is expected to improve quality of life to back up evidence that less radical margins of excision may be just as safe.  

6. Benevolent Tumor Tissue Repository Fighting for the Legacy of our Young

   Rochester, Minn.

   The aim of this study is to create a patient and patient-advocate catalyzed tumor bank for the retrieval, processing, analysis, and maintenance of pre-treatment, post-treatment and (when available) post-mortem soft tissue sarcoma (STS) tissue and tissue data with an emphasis on STSs occurring in younger patients (YP-STS). This resource-platform will be named Project BTTRFLY (Benevolent Tumor Tissue Repository Fighting for the Legacy of our Young).  

7. A Study to Evaluate Preiser's Disease and Its Complications

   Rochester, Minn.

   The purpose of this study is to describe the outcome and complications in surgical management of Preiser',s disease in the past 30 years in the Mayo Clinic.

8. Analysis of Outcomes in Sarcoma Reconstruction Using Intraoperative Fluorescence Angiography

   Jacksonville, Fla.

   The primary objective of the study is to compare outcomes of patients undergoing sarcoma reconstructive surgery using fluorescence angiography with patients undergoing sarcoma reconstructive surgery without fluorescence angiograph.

    

9. A Study to Develop Processes for Tissue Growth for Use in Reconstruction Surgeries

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to develop the procedures for the growth of specific cells and tissues needed for reconstruction surgeries of the head and neck using the waste tissues of other surgeries.

10. A Study of Blood Clotting Response in Patients with a Traumatic Injury

    Rochester, Minn.

    The purpose of this study is to look at the blood’s clotting response in people who have suffered a traumatic injury and compare it with non-injured people.
