Clinical trials Below are current clinical trials.123 studies in Surgery (open studies only). Filter this list of studies by location, status and more. A Study to Analyze Surgical Outcomes and Predictors of Treatment for Hip Diseases Rochester, Minn. This study is designed to: -analyze effects of surgical treatment -improve surgical care and quality of life of patients with hip problems/diseases -ID predictors of surgical outcomes to identify/improve future treatments -Collect data, images, from patients undergoing surgical treatment of hip disorders (we will not be collecting social security numbers to send to Washington University). Blood-Brain Barrier Disruption (BBBD) for Liquid Biopsy in Subjects With GlioBlastoma Brain Tumors Rochester, Minn. The purpose of this study is to evaluate the safety and effectiveness of using Exablate Model 4000 Type-2.0/2.1 in adults with Glioblastoma brain tumors to increase temporarily the permeability of the blood brain barrier, allowing increased passage of circulating free DNA (cfDNA) for sampling and analysis. A Study to Evaluate Mesenchymal Stem Cells for Reducing Anastomotic Stenosis Jacksonville, Fla. The purpose of this study is evaluate the safety of allogeneic adipose derived mesenchymal stem cell (AMSC) use during hemodialysis arteriovenous fistula and arterial bypass creation and its effectiveness on improving access maturation and primary anastomotic patency. A Study to Evaluate Outcomes of Shoulder Arthroplasty Rochester, Minn. The purpose of this study is to evaluate the outcomes and complications in patients who have received a hemiarthroplasty, anatomic total shoulder, or reverse total shoulder arthroplasty. A Study to Develop Liquid Biopsy for Pediatric Brain Tumor Patients Rochester, Minn. The purpose of this study is to confirm detection of the H3K27M mutation in patient biofluids (CSF, blood, urine, saliva) and uncover the molecular histone (alkaline protein) profile of H3K trimethylation and H3S phosphorylation in the circulating nucleosomes isolated from the biofluids of patients with H3K27M tumors. A Study to Compare the Cosmetic Outcome of Superomedial and Inferior Pedicle Breast Reduction Rochester, Minn. The purpose of this study is to compare the cosmetic outcome of Superomedial and Inferior Pedical Breast Reduction. A Registry to Follow Long-Term Outcomes for Mother and Child Pairs After Fetal Surgery for Spina Bifida Rochester, Minn. The purpose of this study is to form a registry of data on the long term physical and mental health outcomes of the mother and child following fetal surgical repair for spina bifida. Treatment Resistant Depression Subcallosal Cingulate Network Rochester, Minn. The purpose of this study is to evaluate the effectiveness and safety of bilateral stimulation of the SCCwm using the Infinity DBS system as an adjunctive treatment of non-psychotic unipolar Major Depression Disorder (MDD) for adults who are experiencing an Major Depressive Episode (MDE) with inadequate response to 4 or more antidepressant treatments. A Registry Called Every Child for Collecting Data and Biology Specimens on Younger Patients with Cancer Rochester, Minn. The purpose of this registry called Every Child, is to collect data and biospecimens from multiple body sources for younger patients with cancer over time. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care. Dynamic Evaluation Of Spinal Alignment And Balance In Adults With Spinal Deformity Using Momentum Spine Rochester, Minn. The purpose of this study is to determine whether the Momentum Spine™ application, with its newly developed dynamic spinal metrics, can accurately and feasibly assess postural parameters in adults with spinal deformity across the continuum of care: conservative management, before and after spinal surgery.

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.
