Pharyngeal sampling for PCR-testing in the investigation of SARS-COV-2 vertical transmission in pregnancy.

The novel COVID-19 global pandemic has raised, among many others, major concerns regarding the impact of infection during pregnancy. Current evidence suggests that vertical transmission from mother to baby, antenatally or intrapartum, does occur, but is uncommon. According to the published reports of infants born to COVID-19-affected mothers, as well as the anecdotal experience of current practices worldwide, it appears that investigations regarding the potential of SARS-COV-2 vertical transmission in pregnancy have so far been based, to a large extent, on PCR testing of neonatal pharyngeal swab samples.

Activin-A exerts a crucial anti-inflammatory role in neonatal infections.

Background: Activin-A is a cytokine with a critical role in infections and associated inflammation in experimental models and humans. Still, the effects of activin-A on neonatal infections remain elusive. Here, we investigated the expression of activin-A in the serum of septicemic preterm and term neonates and in peripheral blood leukocytes stimulated with inflammatory agents in vitro.

Non-steroid anti-inflammatory drugs in the treatment of patent ductus arteriosus in European newborns.

Introduction: Patent ductus arteriosus (PDA) is a common cause of morbidity and mortality among very low birth weight infants and must be treated on an individual basis. Non-steroid anti-inflammatory drugs (NSAIDs) have been used in the treatment of PDA. However, no general guidelines have been followed.

Vascular endothelial growth factor (VEGF) is present in human breast milk and its receptor is present on intestinal epithelial cells.

VEGF (vascular endothelial growth factor) is a multifunctional cytokine active on blood vessel cells. The present study measured VEGF in the aqueous phase of human milk and examined how the concentration varied with gestational age and the duration of lactation after birth. We hypothesized that VEGF-specific receptors were present on the apical surface of intestinal epithelial cells.
