In this first Asian study, the decision outcomes (decision conflict, decision regret, and anxiety) of 262 pregnant women offered noninvasive prenatal test (NIPT) for high-risk Down screening results were assessed. Decision conflict was experienced by 3.5% and level of decisional regret low (mean score 15.7, 95%CI 13.2-18.3). All 13 cases of decisional regret were NIPT acceptors. Elevated anxiety was experienced by 55.9% at the time of decision making about NIPT and persistent in 30.3%. Insufficient knowledge about NIPT was associated with elevated anxiety at decision making (p = .011) and with decisional regret (p = .016). Decisional regret was associated with prolonged anxiety (p = .010).
Only nuchal cord for 3 turns or more was associated with higher incidence of suspected foetal distress. However, the Apgar scores were not affected. Therefore, nuchal cord of any turns was not associated with adverse foetal outcomes. Prenatal ultrasound scan for nuchal cord is, therefore, unnecessary and there should be no differences in management of nuchal cord of any turns.
What are the novel findings of this work?In pregnant women who have recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, anti-SARS-CoV-2 immunoglobulin G (IgG) concentrations at delivery increased with increasing viral load during infection and decreased with increasing infection-to-delivery interval. The median transplacental transfer ratio of IgG was 1.3 and it decreased with increasing viral load during infection.
What are the clinical implications of this work?Even though high viral load during SARS-CoV-2 infection is associated with higher concentration of anti-SARS-CoV-2 IgG antibodies in recovered mothers, it affects negatively the transplacental transfer of IgG to the fetuses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
