Clinical trials Below are current clinical trials.24 studies in Obstetrics and Gynecology (open studies only). Filter this list of studies by location, status and more. Mayo Clinic Umbilical and Placental Tissues Biobank Rochester, Minn. The purpose of this study is to collect paired maternal and umbilical cord blood samples that can be processed for various traits in the blood, including serum, DNA, RNA and cells. The long term goal of this project is to start an Umbilical and Placental Tissues Biobank, which will operate in parallel to the Mayo Clinic Biobank. In future studies, we may use the serum, DNA and RNA obtained from cord blood and your blood to understand health and disease. A Study to Evaluate Time to First Movement for Fetal Surgery Patients Injected with Intramuscular Anesthesia Rochester, Minn. The purpose of this study is to determine the time from intramuscular injection to the time of first fetal movement after a fetal surgery procedure. A Study Of Endometrial Cancer Testing With Vaginal And Endometrial Cell Samples Scottsdale/Phoenix, Ariz., Jacksonville, Fla., Rochester, Minn. The purpose of this study is to collect vaginal and endometrial cell samples to study endometrial cancer. A Study to Assess Maternal and Fetal Outcomes in Pregnancy with Type 1 Diabetes Mellitus and Controls Rochester, Minn. The purpose of this study is to retrospectively and prospectively compare maternal and fetal/newborn clinical outcomes in age-matched pregnant patients with T1D and healthy controls and to assess the relationship between glycemic variability and pregnancy outcomes in the current era. Cancer screening practices of individuals with Lynch Syndrome Rochester, Minn. This is a survey study to describe how women with Lynch syndrome are being screened for gynecologic cancer risk, their perception of cancer risk, and uptake of risk reducing 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.
