Objective  There are limited published data on the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus from mothers to newborns through breastfeeding or from breast milk. The World Health Organization released guidelines encouraging mothers with suspected or confirmed COVID-19 to breastfeed as the benefits of breastfeeding outweighs the possible risk of transmission. The objective of this study was to determine if SARS-CoV-2 was present in the breast milk of lactating mothers who had a positive SARS-CoV-2 nasopharyngeal swab test prior to delivery, and the clinical outcomes for their newborns. Study Design  This was a single-center, observational, prospective cohort study. Maternal–newborn dyads that delivered at New York University Langone Hospital Brooklyn with confirmed maternal SARS-CoV-2 positive screen test at the time of admission were recruited for the study. Breast milk samples were collected during postpartum hospitalization and tested for the presence of SARS-CoV-2 genes N1 and N2 by two-step reverse transcription polymerase chain reaction. Additionally, the clinical characteristics of the maternal newborn dyad, results of nasopharyngeal SARS-CoV-2 testing, and neonatal follow-up data were collected. Results  A total of 19 mothers were included in the study and their infants who were all fed breast milk. Breast milk samples from 18 mothers tested negative for SARS-CoV-2, and 1 was positive for SARS-CoV-2 RNA. The infant who ingested the breast milk that tested positive had a negative nasopharyngeal test for SARS-CoV-2, and had a benign clinical course. There was no evidence of significant clinical infection during the hospital stay or from outpatient neonatal follow-up data for all the infants included in this study. Conclusion  In a small cohort of SARS-CoV-2 positive lactating mothers giving birth at our institution, most of their breast milk samples (95%) contained no detectable virus, and there was no evidence of COVID-19 infection in their breast milk-fed neonates. Key Points Breast milk may rarely contain detectable SARS-CoV-2 RNA and was not detected in asymptomatic mothers. Breast milk with detectable SARS-CoV-2 RNA from a symptomatic mother had no clinical significance for her infant. Breast feeding with appropriate infection control instructions appears to be safe in mother with COVID infection. [ABSTRACT FROM AUTHOR]

Objective This study aims to evaluate impact of respiratory and other neonatal comorbidities on neurodevelopmental outcome in late preterm infants (LPT). Method Retrospective study of LPT infants (34 0/7-36 6/7 weeks' gestation) discharged from the New York University Langone Medical Center neonatal intensive care unit, during January 2006 to December 2010 and received follow-up care up to 2 years of age. Neonatal morbidities were correlated with neurodevelopmental outcomes and assessed by performance on the Mullen Scales of Early Learning during three developmental follow-up visits. Results A total of 99 LPT completed neurodevelopmental assessment up to 2 years of age. Infants with diagnosis of moderate-to-severe respiratory distress syndrome showed a significantly lower performance in the visual reception on the second (p < 0.01) and third visit (p = 0.02), as well as lower performance in the receptive language (visit 2, p = 0.02; visit 3, p < 0.01). A diagnosis of persistent pulmonary hypertension was found to be associated with significantly lower performance in the visual reception at all visits (p < 0.01; p = 0.02; p = 0.02) and in the receptive language on the second and third visit (p = 0.03; p = 0.02). Combined respiratory morbidities were also associated with lower developmental scores in fine motor (visit 2, p < 0.01; visit 3, p = 0.04) as well as expressive language (visit 3, p = 0.02). Conclusion LPT with significant respiratory morbidities are at higher risk for long-term developmental delays, mainly affecting cognitive developmental domains. [ABSTRACT FROM AUTHOR]

Aims: It remains unclear if mode of delivery can have any impact on the neonatal brain. Our aim was to determine in term newborns any differences based on mode of delivery in either neuronal injury biomarkers, phosphorylated axonal neurofilament heavy chain (pNF-H) and ubiquitin C-terminal hydrolase (UCHL1), or brain oxygenation values, regional cerebral tissue oxygen saturation (CrSO2) and cerebral fractional tissue oxygen extraction (CFOE). Methods: An Institutional Review Board approved prospective observational pilot study of well newborns. Serum pNF-H and UCHL1 levels were measured on the day following delivery. CrSO2 values along with CFOE values were also measured using near-infrared spectroscopy (NIRS) and pulse oximetry. Results: There were 22 subjects, 15 born vaginally and seven born by cesarean section. No difference was found in mean pNF-H (107.9±54.3 pg/mL vs. 120.2±43.3 pg/mL, P=0.66) or mean UCHL1 (4.0±3.5 pg/mL vs. 3.0±2.2 pg/mL, P=0.68). No difference was found in mean CrSO2 (80.8±5.3% vs. 80.8±5.6%, P=0.99) or mean CFOE (0.17±0.06 vs. 0.15±0.08, P=0.51). Conclusions: We found no difference in neuronal injury markers between term neonates born vaginally compared to those born by cesarean section. From a neurologic standpoint, this supports current obstetric practice guidelines that emphasize vaginal birth as the preferred delivery method whenever possible. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: Infection with a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic. There are limited data describing the impact of SARS-CoV-2 infection on pregnant mothers and their newborns. The objective of this study is to describe characteristics and outcomes of maternal-newborn dyads with confirmed maternal SARS-CoV-2. METHODS: This was a multicenter, observational, descriptive cohort study with data collection from charts of maternal-newborn dyads who delivered at 4 major New York City metropolitan area hospitals between March 1 and May 10, 2020, with maternal SARS-CoV-2 infection. RESULTS: There were a total of 149 mothers with SARS-CoV-2 infection and 149 newborns analyzed (3 sets of twins; 3 stillbirths). Forty percent of these mothers were asymptomatic. Approximately 15% of symptomatic mothers required some form of respiratory support, and 8% required intubation. Eighteen newborns (12%) were admitted to the ICU. Fifteen (10%) were born preterm, and 5 (3%) required mechanical ventilation. Symptomatic mothers had more premature deliveries (16% vs 3%, P = .02), and their newborns were more likely to require intensive care (19% vs 2%, P = .001) than asymptomatic mothers. One newborn tested positive for SARS-CoV-2, which was considered a case of horizontal postnatal transmission. CONCLUSIONS: Although there was no distinct evidence of vertical transmission from mothers with SARS-CoV-2 to their newborns, we did observe perinatal morbidities among both mothers and newborns. Symptomatic mothers were more likely to experience premature delivery and their newborns to require intensive care. [ABSTRACT FROM AUTHOR]
