Prenatal MRI abdominal volumetrics and outcomes after early surgery or paint-and-wait for giant omphalocele

Daniel Liesman, Steven T. Papastefan, Katherine C. Ott, Elissa Abou Khalil et autres

Giant Omphalocele (GO) poses significant challenges in neonatal management. Standard treatment is paint-and-wait with delayed fascial closure at 1–2 years-of-age. Alternatively, early surgery entails neonatal sac removal with either primary fascial closure or staged GORE-TEX patch-assisted closure. We compared outcomes between early …

Fetoscopic three-port, three-layer open spina bifida repair

Vaidehi Mahadev, Rya Muller, Amir M. Alhajjat, Aimen F. Shaaban et autres

Prenatal surgery for open spina bifida has demonstrated improved neurological and functional outcomes compared to postnatal closure. However, open fetal surgery is associated with increased obstetric complications. Minimally invasive fetoscopic approaches were developed to decrease maternal morbidity from large hysterotomies while preserving …

Extralobar pulmonary sequestration with a transdiaphragmatic gastric attachment: a case report

Rose Rahmani, Johanna M. Borst, David F. Grabski, Amir M. Alhajjat et autres

Extralobar pulmonary sequestration (EPS) has been reported in intradiaphragmatic or intraabdominal locations, but simultaneous involvement of multiple compartments is exceedingly rare. This is the first reported case to our knowledge with simultaneous intrathoracic, transdiaphragmatic, and gastric involvement. A 21-month-old male was prenatally …

Prenatally Educated Friendly NK Cells Expand FOXP3+Tregs and Reduce Tc17 Cells Via Increased TGF-B1 and Decreased GM-CSF Production 4833

Hee Kap Kang, Daniel Liesman, Catherine Redden, Lucas Turner et autres

Abstract Description Prenatal foreign antigen exposure before immune competence results in lifelong antigen-specific tolerance. In our prenatal allotransplantation model, tolerant NK cells (engrafter friendly NK, fNK) suppressed type 1 and 17 allo-specific T cell responses via increased TGF-b1 production and Foxp3+CD4+Treg expansion. …

Co-stimulation of allo responsive NK cells with an NK cell-specific ligand enhances allo-specific rejection and memory in prenatal chimeras 4828

Hee Kap Kang, Daniel Liesman, Catherine Redden, Lucas Turner et autres

Abstract Description Prenatal foreign antigen exposure leads to lifelong stable tolerance, but also can result in non-tolerance to the donor antigen and cause graft rejection. In prenatal allotransplantation model (Balb/c to C57BL/6), allo-specific (Ly49D) NK cells play a key role in engraftment …

Maternal plasma microRNA profiles in twin-twin transfusion syndrome and normal monochorionic twin pregnancies

Steven T. Papastefan, Morgan Langereis, Catherine Redden, Daniel Liesman et autres

Introduction: Ultrasound-based staging systems for twin-twin transfusion syndrome (TTTS) are limited by radiologic expertise, fetal positioning, and timing of the exam, and may benefit from incorporation of objective biochemical measures for diagnosis and prognostication. microRNA expression is altered in amniotic fluid of …
