Disparities in Preterm Infant Emergency Room Utilization and Rehospitalization by Maternal Immigrant Status.

Objective: To evaluate the effects of immigrant mother status and risk factors on the rates of emergency room (ER) visits and rehospitalizations of preterm infants within 90 days after discharge.

Study Design: This was a retrospective cohort study of 732 mothers of 866 preterm infants (<37 weeks of gestational age) cared for in a neonatal intensive care unit (NICU) for >5 days. Medical and demographic data and number of ER visits and rehospitalizations were collected.

Effects of Placental Transfusion on Neonatal and 18 Month Outcomes in Preterm Infants: A Randomized Controlled Trial.

Objective: To assess the effect of delayed cord clamping (DCC) vs immediate cord clamping (ICC) on intraventricular hemorrhage (IVH), late onset sepsis (LOS), and 18-month motor outcomes in preterm infants.

Study Design: Women (n = 208) in labor with singleton fetuses (<32 weeks gestation) were randomized to either DCC (30-45 seconds) or ICC (<10 seconds). The primary outcomes were IVH, LOS, and motor outcomes at 18-22 months corrected age.

Direct observation of enantiomer discrimination of epoxides by chiral salen complexes using ENDOR.

Electron nuclear double resonance (ENDOR) spectroscopy was used to investigate the weak enantioselective binding between chiral salen complexes [VO(1)] ((R,R)- and (S,S)-vanadyl N,N'-bis(3,5-di-tert-butylsalcylidene)-1,2-cyclohexanediamine) and chiral epoxides (e.g., (R)-/(S)-propylene epoxide, 5) in frozen (10 K) solution.

Impact of family health insurance and other environmental factors on universal hearing screen program effectiveness.

Objective: The study objective was to evaluate the relationship among health insurance type, other demographic factors, and newborn hearing screen compliance and outcomes.

Study Design: The cohort consisted of 39,153 infants screened in Rhode Island between July 1, 1995 and June 30, 1998. Multivariate analyses were completed to evaluate relationships between health insurance type and completion of the in-hospital hearing screen and the rescreen, if indicated.
