Antibody levels against respiratory syncytial virus fusion protein conformations and lack of association with life-threatening infection in previously healthy infants.

Background: Humoral immune response against the pre-fusion (pre-F) conformation of respiratory syncytial virus (RSV) F protein has been proposed to play a protective role against infection. An RSV pre-F maternal vaccine has been recently approved in several countries to protect young infants against RSV. We aimed to assess serum IgG titers against the pre-F and post-F conformations of RSV F protein and their association with life-threatening RSV disease (LTD) in previously healthy infants.

Postpartum use of oxytocin and volume of placental transfusion: a randomised controlled trial.

Objective: To assess whether oxytocin administered before clamping the umbilical cord modifies the volume of placental transfusion.

Design: Randomised controlled trial.

Methods: Mothers of term infants born vigorous by vaginal delivery with informed consent provided in early labour were randomly assigned to oxytocin (10 IU) given intravenously within 15 s of birth (group 1) or after clamping the umbilical cord 3 min after delivery (group 2).

[Recommendations for palivizumab use. Update 2015].

This recommendation updates the Argentinean Pediatrics' Neonatal Committee (CEFEN) ones published in 2007. The respiratory syncytial virus is the most frequent agent for lower respiratory infection. Tiny premature, bronchopulmonary dysplasia and significant hemodynamic congenital heart disease babies are the most vulnerable populations.

Effect of gravity on volume of placental transfusion: a multicentre, randomised, non-inferiority trial.

Background: Delayed cord clamping allows for the passage of blood from the placenta to the baby and reduces the risk of iron deficiency in infancy. To hold the infant for more than 1 min at the level of the vagina (as is presently recommended), on the assumption that gravity affects the volume of placental transfusion, is cumbersome, might result in low compliance, and interferes with immediate contact of the infant with the mother. We aimed to assess whether gravity affects the volume of placental transfusion

Methods: We did a multicentre non-inferiority trial at three university-affiliated hospitals in Argentina.

[Delivery room practices in infants born through meconium stained amniotic fluid: a national survey].

Unlabelled: Based on the results of two large RCTs, guidelines from NRP/AAP, ILCOR, ACOG, and from Argentinean scientific societies for intrapartum and postpartum management of pregnancies with Meconium Stained Amniotic Fluid (MSAF) have radically changed. However, there are no data as to current delivery room management of infants born through MSAF.

Objectives: 1) To assess current delivery room approaches in infants born through MSAF in Argentina; 2) To evaluate the adherence to NRP/AAP recommendations among different centers.
