Comparative Analysis of Spinal versus General Anesthesia for Vaginal Natural Orifice Transluminal Endoscopic Tubal Sterilization: A Prospective, Randomized Controlled Trial
Principal Investigator: Meredith Gray, M.D.
This study investigates whether using a small dose of spinal anesthesia is a safe and effective alternative to standard general anesthesia for a specific type of surgery (VNOTES tubal sterilization). It will assess complications during and after surgery and compare pain, nausea, recovery time, and patient satisfaction between the two anesthesia methods.
GLP-1 effects on lean mass and bone health in midlife women (GLOW)
Principal Investigator: Johanna Finkle, M.D.
Co-Investigator: Holly Hull, Ph.D.

Kangaroo Care in the Operating Room
Principal Investigator: Meredith Gray, M.D.
Co-Investigators: Angela Martin, M.D., Sydney Edmisten, M.D. (resident), Sharon Fitzgerald Wolff, Ph.D., MPH
This randomized controlled trial compares the outcomes of placing newborns on their mother's chest immediately after a scheduled cesarean delivery (kangaroo care) with the standard practice of taking the baby to an assessment warmer first. The hypothesis is that immediate skin-to-skin contact during cesarean section will reduce the need for pain and anxiety medications for the mother, enhance her satisfaction with the procedure, and won't lead to differences in the baby's health measures like the Apgar score, neonatal ICU admission, maternal infection rates, or blood loss. Enrollment is complete.

This current phase focuses on examining the long-term neurodevelopmental outcomes in the children of those participants.
Promoting Shared Decision Making in Periviable Care: A randomized controlled trial of the Periviable GOALS Decision Support Tool
Principal Investigator: Megan Thomas, M.D.
This study compares a decision support tool called Periviable GOALS with standard care for pregnant people and their support persons hospitalized for a potential periviable delivery.

REDUCE Trial – Reducing Prolapse Recurrence by Reducing Genital Hiatus
Principal Investigator: Melanie Meister, M.D.
The decision to include a posterior repair during a surgical procedure called sacrocolpopexy, which treats vaginal prolapse, is debated among surgeons. This study aims to determine if adding this procedure reduces the risk of prolapse recurrence. We hypothesize that the addition of a posterior repair at the time of sacrocolpopexy will not reduce the risk of prolapse recurrence but may increase the likelihood of discomfort during defecation and painful intercourse.

Patients undergoing ovarian stimulation will provide blood and endometrial biopsies (taken during oocyte retrieval under anesthesia and not affecting future pregnancy). We aim to delineate the expression of these markers in endometrial tissue and evaluate serum miR-451a as a prognostic marker for embryo implantation success.

In Vitro Maturation of Oocytes and Hormonal Effect on Reproductive Tissue in Transgender Men
Principal Investigator: Katherine Roby, M.D.
This study aims to find a better way to preserve fertility in transgender men, as the current method of freezing eggs has drawbacks. Researchers will experiment with growing eggs in a lab dish from ovarian tissue removed during surgery, and they also want to understand how long-term testosterone exposure affects reproductive organs. This work could not only help transgender individuals but also expand our knowledge of ovarian function and related conditions like polycystic ovary syndrome.
Reproductive Endocrinology and Infertility (REI) Biobank
Principal Investigator: Courtney Marsh, M.D.
The Reproductive Endocrinology and Infertility (REI) Biobank was created so researchers can utilize it to investigate the causes of infertility. The REI Biobank consists of blood and tissue from patients evaluated and treated for infertility or underwent surgery at the University of Kansas. These samples provide material for the discovery, confirmation, and validation of information related to disease pathology, biomarkers of said disease and therapeutic targets.
REST-MED12 Pathways in the Regulation of Estrogen - Progesterone Sensitivity in Uterine Leiomyoma

Molecular Pathogenesis of Uterine Leiomyomas
Principal Investigator: Vargheese Chennathukuzhi, Ph.D.
This research focuses on understanding uterine fibroids. The study explores how a protein, GPR10, when activated, may promote the growth of these tumors and how the loss of another protein, REST, might be a critical step in the development of uterine fibroids. The goal is to gain insights into the mechanisms behind uterine fibroid formation, potentially leading to new therapies for this condition.
REST/NRSF, miRNAs and Tissue Remodeling in Adenomyosis Pathophysiology
Principal Investigator: Warren Nothnick, Ph.D.
This study aims to understand a uterine condition called adenomyosis, which can cause heavy and painful periods, pelvic pain, discomfort during intercourse, and reproductive issues. The researchers are investigating if a specific molecular pathway involving genes and small molecules called miRNAs plays a role in the development of adenomyosis, using both human and mouse models to explore potential treatments.
Assessment of Normal and Abnormal Placental Structure/Function during Pregnancy and Disease
Principal Investigator: Soumen Paul, Ph.D.
Co-Investigators: Angela Martin, M.D.
The placenta is a vital organ during pregnancy that transfers essential nutrients, removes waste, and produces hormones crucial for fetal and maternal health. Problems with placental function can impact fetal development and increase the risk of health issues for both the mother and child. This research aims to use human placental models to study differences in normal and disease conditions and monitor transport and metabolism by the placenta to ultimately understand and enhance pregnancy outcomes and lifelong health for both mothers and babies.
