Maternal and Newborn Hospital Outcomes of Perinatal SARS-CoV-2 Infection: A National Registry.

OBJECTIVES: The American Academy of Pediatrics National Registry for the Surveillance and Epidemiology of Perinatal coronavirus disease 2019 (COVID-19) (NPC-19) was developed to provide information on the effects of perinatal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: National Registry for the Surveillance and Epidemiology of Perinatal COVID-19 participating centers entered maternal and newborn data for pregnant persons who tested positive for SARS-CoV-2 infection between 14 days before and 10 days after delivery. Incidence of and morbidities associated with maternal and newborn SARS-CoV-2 infection were assessed. RESULTS: From April 6, 2020 to March 19, 2021, 242 centers in the United States centers reported data for 7524 pregnant persons; at the time of delivery, 78.1% of these persons were asymptomatic, 18.2% were symptomatic but not hospitalized specifically for COVID-19, 3.4% were hospitalized for COVID-19 treatment, and 18 (0.2%) died in the hospital of COVID-related complications. Among 7648 newborns, 6486 (84.8%) were tested for SARS-CoV-2, and 144 (2.2%) were positive; the highest rate of newborn infection was observed when mothers first tested positive in the immediate postpartum period (17 of 125, 13.6%). No newborn deaths were attributable to SARS-CoV-2 infection. Overall, 15.6% of newborns were preterm: among tested newborns, 30.1% of polymerase chain reaction-positive and 16.2% of polymerase chain reaction-negative were born preterm (P < .001). Need for mechanical ventilation did not differ by newborn SARS-CoV-2 test result, but those with positive tests were more likely to be admitted to a NICU. CONCLUSIONS: Early in the pandemic, SARS-CoV-2 infection was acquired by newborns at variable rates and without apparent short-term effects. During a period that preceded widespread availability of vaccines, we observed higher than expected numbers of preterm births and maternal in-hospital deaths.

Perinatal COVID-19 maternal and neonatal outcomes at two academic birth hospitals.

OBJECTIVE: Describe 1-month outcomes among newborns of persons with perinatal COVID-19. STUDY DESIGN: Prospective observational study of pregnant persons who tested positive for SARS-CoV-2 between 14 days before and 3 days after delivery and their newborns, from 3/2020 to 3/2021 at two urban high-risk academic hospitals. Phone interviews were conducted to determine 1-month newborn outcomes. RESULTS: Among 9748 pregnant persons, 209 (2.1%) tested positive for perinatal SARS-CoV-2. Symptomatically infected persons were more likely to have a preterm delivery due to worsening maternal condition and their newborns were more likely to test positive for SARS-CoV-2 compared with asymptomatic persons. Six of 191 (3.1%) infants tested were positive for SARS-CoV-2; none had attributable illness before discharge. Of 169 eligible families, 132 (78.1%) participated in post-discharge interviews; none reported their newborn tested positive for SARS-CoV-2 by 1 month of age. CONCLUSION: Symptomatic perinatal COVID-19 had a substantial effect on maternal health but no apparent short-term effect on newborns.

Enteral Feeding as an Adjunct to Hypothermia in Neonates with Hypoxic-Ischemic Encephalopathy.

BACKGROUND: Withholding enteral feedings during hypothermia lacks supporting evidence. OBJECTIVES: We aimed to determine if minimal enteral nutrition (MEN) during hypothermia in patients with hypoxic-ischemic encephalopathy was associated with a reduced duration of parenteral nutrition, time to full oral feeds, and length of stay, but would not be associated with increased systemic inflammation or feeding complications. METHODS: We performed a pilot, retrospective, matched case-control study within the Florida Neonatal Neurologic Network from December 2012 to May 2016 of patients who received MEN during hypothermia (n = 17) versus those who were not fed (n = 17). Length of stay, feeding-related outcomes, and brain injury identified by MRI were compared. Serum inflammatory mediators were measured at 0-6, 24, and 96 h of life by multiplex assay. MRI were scored using the Barkovich system. RESULTS: MEN subjects had a reduced length of hospital stay (mean 15 ± 11 vs. 24 ± 19 days, p < 0.05), days receiving parenteral nutrition (7 ± 2 vs. 11 ± 6, p < 0.05), and time to full oral feeds (8 ± 5 vs. 18 ± 18, p < 0.05). MEN was associated with a significantly reduced serum IL-12p70 at 24 and 96 h (p < 0.05). Brain MRI scores were not significantly different between groups. CONCLUSION: MEN during hypothermia was associated with a reduced length of stay and time to full feeds, but did not increase feeding complications or systemic inflammation.
