[Benefits of home-based administration of palivizumab in high-risk groups].

Unlabelled: Palivizumab, a humanized monoclonal antibody against the respiratory syncytial virus (RSV), currently is indicated in groups at higher risk of developing severe RSV disease, such as extreme premature infants and patients with hemodynamically significant heart disease. In Chile, this strategy is guaranteed by Law 20850 (Ricarte Soto Law). Nevertheless, barriers to its administration included the need to transfer these labile patients and exposure to other users, with the risk of contagion in waiting rooms.

[Rehospitalization of preterm infants below 32 weeks of gestational age in the first 2 years post discharge].

Unlabelled: Preterm infants, especially those of lower gestational age (GA), are at high risk of hospital readmission in the early years.

Objective: To describe the frequency and characteristics of readmissions in preterm infants younger than 32 weeks of GA or weighing less than 1500 g (< 32w/< 1500 g) at 2 years post-discharge from neonatology.

Patients And Method: Retrospective observational study of a cohort of newborns < 32w/< 1500 g discharged from a public health care center (2009-2017).

Extremely and very preterm children who were born appropriate for gestational age show no differences in cortisol concentrations or diurnal rhythms compared to full-term children.

Objectives: The objective of this study was to compare the diurnal variations in cortisol and cortisone concentrations in serum and saliva among extremely preterm (EPT), very preterm (VPT), and full-term (FT) children, all born appropriate for gestational age (AGA).

Methods: EPT, VPT, and FT children, all born AGA, were recruited from two healthcare centers. Cortisol and cortisone concentrations in serum and saliva were measured by liquid chromatography-mass spectrometry (LC‒MS).

Mortality in very low birth weight (VLBW) infants in South American NEOCOSUR Neonatal Network: timing and causes.

Introduction: Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network.

Objective: Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network.

Population And Methods: Observational, multicenter cohort study; retrospective analysis of data collected prospectively.

Survival and Survival without Major Morbidity Seem to Be Consistently Better throughout Gestational Age in 24- to 30-Week Gestational Age Very-Low-Birth-Weight Female Infants Compared to Males.

Introduction: Several studies showed advantages in outcomes for very-low-birth-weight (VLBW) female infants. It has been suggested that recent advances in perinatal care might have benefited boys relatively more than girls, making differences disappear.

Objectives: The aims of the study were (1) to determine if sex differences in survival and survival without morbidity in VLBW infants are still present in the context of more advanced perinatal care and (2) to know whether these differences are consistent throughout gestational age (GA).
