Background: Scheduled administration of analgesics was proven superior to on-demand dosing following cesarean deliveries. However, this protocol was not compared after vaginal delivery.

Should pregnant women be screened for SARS-CoV-2 infection? A prospective multicenter cohort study.

Objective: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ranges from asymptomatic to severe infection. We aimed to compare the prevalence of COVID-19 in asymptomatic pregnant versus nonpregnant women in order to establish recommendations for a COVID-19 screening strategy.

Methods: A prospective multicenter cohort study was conducted.

Vertical transmission and humoral immune response following maternal infection with SARS-CoV-2: a prospective multicenter cohort study.

Objective: To explore maternal humoral immune responses to SARS-CoV-2 infection and the rate of vertical transmission.

Methods: A prospective cohort study was conducted at two university-affiliated medical centers in Israel. Women positive for SARS-CoV-2 reverse-transcription-polymerase-chain-reaction (RT-PCR) test during pregnancy were enrolled just prior to delivery.
