Fatty acid ethyl esters in meconium: A biomarker of fetal alcohol exposure and effect.

To determine if meconium fatty acid ethyl esters (FAEE) in rat pups is a good biomarker of prenatal exposure and effect to alcohol, three groups of pregnant rats were studied: one control (pair fed) and two treatment groups given 25% alcohol at 2.2 or 5.5 g kg d.

Umbilical Cord Blood Lead Level Disparities between Flint and Detroit.

Objective: The lead-in-water impact of the Flint water crisis on the youngest and most neurodevelopmentally vulnerable population was largely unknown. The objective of this study was to investigate and compare cord blood lead levels (CBLLs) in newborns in Flint, Michigan, after the Flint water crisis, to a group of Detroit newborns.

Study Design: Mothers of 99 Flint newborns were surveyed about potential lead exposures.

Outcome of Preterm Infants with Transient Cystic Periventricular Leukomalacia on Serial Cranial Imaging Up to Term Equivalent Age.

Objective: To determine the outcome of preterm infants whose cystic periventricular leukomalacia "disappeared" on serial screening cranial imaging studies.

Study Design: Infants ≤26 weeks of gestation born between 2002 and 2012 who had cranial imaging studies at least twice, the most abnormal study at <28 days of age and another closest to 36 weeks, were reviewed. The outcome of late death (after 36 weeks postmenstrual age) or neurodevelopmental impairment (NDI) in surviving infants at 18-26 months corrected age was compared between the infants with no cystic periventricular leukomalacia on both studies and cystic periventricular leukomalacia that disappeared (cystic periventricular leukomalacia at <28 days but not at 36 weeks), persisted (cystic periventricular leukomalacia on both studies), or appeared late (cystic periventricular leukomalacia only at 36 weeks).

Markers of Successful Extubation in Extremely Preterm Infants, and Morbidity After Failed Extubation.

Objectives: To identify variables associated with successful elective extubation, and to determine neonatal morbidities associated with extubation failure in extremely preterm neonates.

Study Design: This study was a secondary analysis of the National Institute of Child Health and Human Development Neonatal Research Network's Surfactant, Positive Pressure, and Oxygenation Randomized Trial that included extremely preterm infants born at 24 to 27 weeks' gestation. Patients were randomized either to a permissive ventilatory strategy (continuous positive airway pressure group) or intubation followed by early surfactant (surfactant group).

Cord blood lead level in an urban inner-city hospital.

Lead levels were measured by inductively coupled plasma mass spectrometry (ICP-MS) in umbilical cord blood samples of 150 neonates in an urban inner-city hospital. The mean (SD) gestation and birth weight of our cohort were 38.8 (1.

Randomized placebo-controlled trial of sucrose analgesia on neonatal skin blood flow and pain response during heel lance.

Objectives: To evaluate the effect of oral sucrose on skin blood flow (SBF; perfusion units; PU) measured by Laser Doppler Imager (LDI) in term newborns and pain response (Neonatal Infant Pain Scale score; NIPS score) during heel lance; (2) determine SBF changes during heel lance; and (3) the relationship between SBF and NIPS.

Materials And Methods: Term infants ≤7 days old (n=56) undergoing routine heel lance were randomized to pretreatment with 2.0 mL oral 24% sucrose (n=29) or sterile water (n=27) in a double-blinded, placebo-controlled trial.
