To estimate risk of NEC for ELBW infants as a function of preterm formula and maternal milk (MM) intake and calculate the impact of suboptimal feeding on NEC incidence and costs

Behavioral Deficits at 18-22 Months of Age Are Associated with Early Cerebellar Injury and Cognitive and Language Performance in Children Born Extremely Preterm.

OBJECTIVE: To investigate associations in toddlers born extremely preterm (\u3c28 \u3eweeks) between neonatal neuroimaging and 18- to 22-month developmental and behavioral outcomes. STUDY DESIGN: Cohort analysis from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Surfactant Positive Airway Pressure and Pulse Oximetry Trial Neuroimaging and Neurodevelopmental Outcomes Study of infants born extremely preterm. Subjects underwent cranial ultrasonography and near-term magnetic resonance imaging (MRI). At 18-22 months of corrected age, the assessment included the Brief Infant Toddler Social Emotional Assessment (BITSEA) Problem and Competence Scale scores and the Bayley Scales of Infant Development, Third Edition (Bayley-III). The BITSEA Problem Scale assesses dysregulation; the Competence Scale assesses social-emotional competence. We examined associations of Problem and Competence scores and positive screen rates with cranial ultrasonography and near-term MRI. Mean BITSEA and Bayley-III scores were compared using ANOVA and positive screen rates with the χ RESULTS: Of the 397 children, positive BITSEA screens were found in 34% for the Problem score and 26% for the Competence score. Presence of lesions on near-term MRI that included cerebellar lesions were significantly associated with lower BITSEA Competence but not with Problem scores; Competence scores were inversely related to the presence/significance of lesions. Positive screens on Competence scores and on both Competence and Problem scores were significantly associated with Bayley-III cognitive and language scores \u3c85 \u3e(P \u3c .001). CONCLUSIONS: Social-emotional competence contributes to deficits in cognitive and language development. Presence of injury on near-term MRI that includes cerebellar lesions is associated with later social-emotional competence and may be a useful predictor to guide early assessment and intervention.

Developmental Outcomes of Extremely Preterm Infants with a Need for Child Protective Services Supervision.

OBJECTIVE: To evaluate neurodevelopmental outcomes of preterm infants with need for Child Protective Services (CPS) supervision at hospital discharge compared with those discharged without CPS supervision. STUDY DESIGN: For infants born at2013, prospectively collected maternal and neonatal characteristics and 18- to 26-month corrected age follow-up data were analyzed. Bayley-III cognitive and language scores of infants with discharge CPS supervision were compared with infants without CPS supervision using regression analysis while adjusting for potentially confounding variables, including entering CPS after discharge from the hospital. RESULTS: Of the 4517 preterm infants discharged between 2006 and 2013, 255 (5.6%) were discharged with a need for CPS supervision. Mothers of infants with CPS supervision were significantly more likely to be younger, single, and gravida ≥3; to have less than a high school education; and to have a singleton pregnancy and less likely to have received prenatal care or antenatal steroids. Despite similar birth weight and medical morbidities, the CPS group had longer hospital stays compared with the non-CPS group. In adjusted analysis, cognitive scores were points lower (B = -1.94; 95% CI, -3.88 to -0.08; P = .04) in the CPS at discharge group compared with the non-CPS group. In children who entered CPS supervision after hospital discharge (an additional 106 infants), cognitive scores were 4 points lower (β = -4.76; 95% CI, -7.47 to -2.05; P \u3c .001) and language scores were 5 points lower (β = -4.93; 95% CI, -8.00 to -1.86; P = .002). CONCLUSION: Extremely preterm infants discharged from the hospital with CPS supervision or entering CPS postdischarge are at increased risk for cognitive delay at 2 years of age. Opportunities exist to intervene and potentially improve outcomes in this vulnerable group of children

Mortality and Neurodevelopmental Outcomes in the Heart Rate Characteristics Monitoring Randomized Controlled Trial

To test whether the composite outcome of death or neurodevelopmental impairment (NDI) at 18-22 months corrected age for infants ≤1000 g at birth is decreased by continuous monitoring of heart rate characteristics during neonatal intensive care. We studied a subset of participants enrolled in a multicenter randomized trial of heart rate characteristics monitoring. Survivors were evaluated at 18-22 months corrected age with a standardized neurologic examination and the Bayley Scales of Infant Development-III (BSID-III). NDI was defined as Gross Motor Function Classification System of >2 (moderate or severe cerebral palsy), BSID-III language or cognitive scores of <70, severe bilateral hearing impairment, and/or bilateral blindness. The composite outcome, death or NDI, was obtained for 628 of 884 study infants (72%). The prevalence of this outcome was 44.4% (136/305) among controls (infants randomized to heart rate characteristics monitored but not displayed) and 39.4% (127/321) among infants randomized to heart rate characteristics monitoring displayed (relative risk, 0.89; 95% CI, 0.74-1.07; P = .22). Mortality was reduced from 32.0% (99/309) among controls to 24.2% (79/327) among monitoring displayed infants (relative risk, 0.75; 95% CI, 0.59 to 0.97; P = .028). The composite outcomes of death or severe CP and death or mildly low Bayley cognitive score occurred less frequently in the displayed group (P < .05). We found no difference in the composite outcome of death or NDI for extremely preterm infants whose heart rate characteristics were and were not displayed during neonatal intensive care. Two outcomes that included mortality or a specific NDI were less frequent in the displayed group

Potential missed opportunities for antenatal corticosteroid exposure and outcomes among periviable births: observational cohort study

Test the hypothesis potential missed opportunities for antenatal corticosteroids increase as gestational age decreases and are associated with adverse outcomes. Observational cohort study. 24 US centers in the Neonatal Research Network. Actively treated infants 22-25 weeks' gestation and birth weight 401-1000 grams, without major birth defects, born 2006-2018. Potential missed opportunity was defined as no antenatal corticosteroids but did have prenatal antibiotics, and/or magnesium sulfate, and/or prolonged rupture of membranes. Poisson regression models adjusted for baseline characteristics. Antenatal corticosteroid exposure, mortality, and severe intracranial hemorrhage or periventricular leukomalacia. 6966 (87.5%) were exposed to antenatal corticosteroids, 454 (5.7%) had no exposure but potential missed opportunities for antenatal corticosteroid exposure, and 537 (6.7%) had no exposure and no evidence of potential missed opportunities. Compared with infants born at 25 weeks, potential missed opportunities for antenatal corticosteroid exposure were more likely at 22 weeks (adjusted relative risk (aRR) [95% CI] 11.06 [7.52-16.27]) and 23 weeks (3.24 [2.44-4.29]) but did not differ at 24 weeks (1.08 [0.82-1.42]). Potential missed opportunities for antenatal corticosteroids decreased over time at 22-23 weeks' gestation. Antenatal corticosteroid exposed infants had lower risk of death (31.0% vs 54.8%; 0.77 [0.70-0.84]) and survivors had lower risk of severe brain injury (25.0% v 44.5%; 0.64 [0.55-0.73]) compared with infants with potential missed opportunities. Potential missed opportunities for antenatal corticosteroid exposure increased with decreasing gestational age and were associated with higher rates of death and severe brain injury among actively treated periviable births
