Duration of biophysical profile in periviable and very preterm low-risk pregnancies.

Background: In recent years, perinatal viability has shifted from 24 to 22 weeks of gestation at many institutions after improvements in survival in neonates delivered at the limit of viability. Monitoring these fetuses is essential because antenatal interventions with resuscitation efforts are available for patients at risk of delivery at the limit of viability. However, fetal monitoring using biophysical profiles has not been extensively studied in very preterm pregnancies, particularly in the periviable period (20 weeks 0 days to 23 weeks 6 days).

Outcomes in Pregnant Adolescent Patients Infected With SARS-CoV-2.

Background: Pregnant patients with coronavirus disease 2019 (COVID-19) are at risk for adverse pregnancy outcomes. Although clinical outcomes for pregnant adults have been reported, the impact of COVID-19 on adolescents is lacking. We sought to evaluate obstetric outcomes of pregnant adolescents infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and compare them with uninfected adolescent controls.
