1. A Study to Evaluate Novel Nipple Reconstruction Technique Using Nipple Sharing of a Half-Split Nipple in Female-to-Male Transgender Chest-Wall Contouring

   Rochester, Minn.

   The purpose of this study is to describe a new surgical technique for nipple reconstruction in female-to-male transgender chest wall reconstruction and demonstrate its safety, patient satisfaction, aesthetic evaluation and complications. Subsequently, correlate these findings to assess overall surgical and clinical outcomes.

2. Colorectal Resection in Emergency General Surgery

   Rochester, Minn.

   The purpose of this study is to define the early postoperative morbidity and mortality of EGS patients undergoing colon resection in the urgent/emergent setting, with a specific focus on the comparison of patients undergoing colonic anastomosis versus diversion.

3. Study to Validate the Use of Hand-Held Mobile 3D Scanning to Obtain Volumetric Measurements for Staging Disease Severity in Lymphedema Patients

   Jacksonville, Fla.

   The purpose of this study is to validate the use of LymphaTech's Hand-Held Mobile 3D Scanning to obtain volumetric measurements in order to stage disease severity in patients diagnosed with lymphedema, and also serve as an imaging biomarker for microsurgical treatment response.

4. A Study to Evaluate the Safety and Immunological Effect of Pembrolizumab in Resectable or Borderline Resectable Pancreatic Cancer

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to investigate whether pembrolizumab (MK-3475 ) can be used safely during neoadjuvant treatment and can improve the body's immune response against pancreatic cancer. Pembrolizumab has been approved for treatment of patients with melanoma but has not been proven to be safe or helpful in patients with pancreatic cancer and is not approved by the U.S. Food and Drug Administration (FDA) for this purpose.

5. Accuracy of Patient-Specific Implants and Instrumentation in Total Hip Arthroplasty

   Rochester, Minn.

   This is a prospective clinical trial examining only subjects who undergo THA with PSI. The purpose of this study is to compare the alignment accuracy of patient-specific implants versus traditional off-the-shelf implants in total hip arthroplasty using prior literature-derived data as controls.

6. A Study to Evaluate the Venn Ovarian CAncer Liquid Biopsy

   Jacksonville, Fla.

   The primary purpode of this study is to determine the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the InterVenn Ovarian Cancer Liquid Biopsy among women with ovarian adnexal mass for which a surgery is planned.

7. A Study to Evaluate Support Services for Managing Urological Conditions

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to assess if men and women seeking care for urological diseases have interest in support services in conjunction with standard of care.

8. Dendritic Cell Therapy After Cryosurgery in Combination With Pembrolizumab in Treating Patients With Stage III-IV Melanoma That Cannot Be Remove by Surgery

   Rochester, Minn.

   This phase Ib/II trial studies how well dendritic cell therapy after cryosurgery in combination with pembrolizumab works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Cryosurgery, also known as cryoablation or cryotherapy, kills tumor cells by freezing them. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving dendritic cell therapy after cryosurgery in combination with pembrolizumab may work better in treating patients with melanoma.

9. A Study to Evaluate Vascularized Lymph Node Transfer Coverage

   Rochester, Minn.

   The purpose of this study is to investigate outcomes for all patients with upper or lower extremity lymphedema with lymph node transfer in a two stage procedure involving dermal regeneration followed by split thickness skin graft (STSG) and compared to patients only receiving STSG for wound coverage.

    

10. Early Outcomes of Volar Capsulodesis for the Treatment of Scapholunate Ligament Injury

    Rochester, Minn.

    The purpose of this study is to:

    1. To provide a comprehensive review of Mayo Clinic’s experience with volar SLIL capsulodesis
    2. Investigate the relationships between patient risk factors and clinical variables with functional outcomes and patient satisfaction
    3. Determine rates of complication, revision surgeries and salvage for failure
