Research and Education Fall 2014
- Pedro Argoti, M.D.,completed his fetal intervention fellowship with The Fetal Center and began his fellowship in genetics and
maternal-fetal medicine at Johns Hopkins University School of Medicine. Dr. Argoti was the Center’s first fetal intervention fellow.
- Roopali Donepudi, M.D.,began her fetal intervention fellowship at The Fetal Center at Children’s Memorial Hermann Hospital in July.
She joins The Fetal Center following completion of her maternal-fetal medicine fellowship at Albert Einstein College of Medicine.
- Saul Snowise, M.D.,a second-year maternal-fetal medicine fellow at McGovern Medical School at UTHealth, joined The Fetal Center at Children’s
Memorial Hermann Hospital to concentrate on research and clinical training in fetal intervention for the next two years of his
- Ramesha Papanna, M.D., M.P.H., continues to investigate the causes of preterm labor and preterm premature rupture of membranes
in twin-twin transfusion syndrome. Basic science investigations are under way to study changes in the fetal membranes and
amniotic fluid that occur in TTTS that may contribute to preterm delivery.
- Dr. Papanna, in collaboration with Kenneth Moise Jr., M.D., is continuing an investigation in a swine model to address the sealing of
the site of fetoscopic entry at the time of fetal intervention. This work is funded by an RO1 grant from the National Institutes of
Health in collaboration with Russell Stewart, Ph.D., of the University of Utah.
- Dr. Papanna and Dr. Moise, in collaboration with Stephen Fletcher, D.O., in the division of Pediatric Neurosurgery at McGovern Medical School, continue to investigate methods in the development of a minimally invasive approach to in utero repair of
myelomeningocele. In collaboration with Scheffer Tseng, M.D., Ph.D., of the Ocular Surface Center, P.A., preliminary results in an
ovine model for MMC indicate that the processed outer covering of human umbilical cord has substantial regenerative properties
as a patch for in utero repair. Additional experiments are planned for spring 2015.
- Dr. Moise, in collaboration with Judith Smith, Pharm.D., is studying the transplacental passage of remifentanil in patients
undergoing intrauterine transfusion.
- Saul Snowise, M.D., visited Children’s Hospital of Philadelphia to learn the methodology of a rat model for fetal myelomeningocele
(MMC). This fall, experiments are planned at McGovern Medical School to study various patch materials that can be utilized for the
minimally invasive repair of fetal MMC.
- Dr. Snowise has initiated a prospective trial on fetal thigh volume determined by ultrasound in the prediction of subsequent
ambulation in fetuses affected with spina bifida.
- Helena Gardiner, M.D., Ph.D., has secured specialized software for the study of myocardial stress forces in an effort to detect early
cardiac changes in monochorionic twins that will eventually develop twin-twin transfusion. Human IRB approval is pending for a
The American Journal of Perinatology will publish a monograph of articles sponsored by The Fetal Center at Children’s Memorial
Hermann Hospital and the Department of Obstetrics, Gynecology and Reproductive Sciences at McGovern Medical School.
The monograph is a summarization of articles based on presentations by invited speakers at the Complicated Monochorionic
Twins workshop, hosted by The Fetal Center in 2013. Kenneth Moise Jr., M.D., serves as the guest editor for the special edition.
