Objective: Identify the potential for and risk factors of SARS-CoV-2 vertical transmission.Methods: Symptomatic pregnant women with COVID-19 diagnosis in whom PCR for SARS-CoV-2 was performed at delivery using maternal serum and at least one of the biological samples: cord blood (CB), amniotic fluid (AF), colostrum and/or oropharyngeal swab (OPS) of the neonate. The association of parameters with maternal, AF and/or CB positivity and the influence of SARS-CoV-2 positivity in AF and/or CB on neonatal outcomes were investigated.Results: Overall 73.4% (80/109) were admitted in hospital due to COVID-19, 22.9% needed intensive care and there were four maternal deaths. Positive RT-PCR for SARS-CoV-2 was observed in 14.7% of maternal blood, 13.9% of AF, 6.7% of CB, 2.1% of colostrum and 3.7% of OPS samples. The interval between
These findings require further clinical studies to assess the hypothesis that the rearrangement of liver microcirculation through the detection of CD34 might be relevant in prognostic assessment of cirrhotic patients.
The present results suggest that cCTG parameters may be useful in the management of cases with early onset placental insufficiency in association with Doppler velocimetry assessment, and that basal FHR and DV-PIV are most clearly in association with acidemia at birth.
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.
