Fetal Thymus Involution as a Predictor of Adverse Neonatal Outcomes (TIPS)

The thymus gland is a specialized organ in the chest that plays a central role in the adaptive immune system throughout development until puberty. In response to stress, the fetal thymus gland may shrink, or involute. The investigators propose a prospective cohort study that will enroll pregnant women admitted to labor and delivery for the management of preterm labor and/or preterm premature rupture of membranes from 28-36 weeks gestation. Based on sonographic thymus measurements, the investigators will develop a clinical prediction tool to identify babies who are at increased risk for adverse neonatal outcomes. A reliable non-invasive predictor of adverse neonatal outcome using thymic ultrasound measurements has the potential to affect clinical management, improve outcomes for premature babies, and direct further research efforts.

Women Admitted to Labor and Delivery for the Management of Preterm Labor and/or Preterm Premature Rupture of Membranes (PPROM)
