Preliminary data in Europe have suggested a reduction prematurity rates during the COVID-19 pandemic, implying that contingency measures could an impact on rates. We designed population-based prevalence proportion study to explore potential link between national lockdown and change preterm births stillbirths. Adjusted multivariate analyses did not show any decrease proportions period with respect whole prelockdown or comparison periods (2015-2019): 6.5% (95%CI 5.6-7.4), 6.6% 6.5-6.8), 6.2%...

Objective To evaluate the association between neuroimaging and outcome in infants with congenital cytomegalovirus (cCMV), focusing on qualitative MRI quantitative diffusion-weighted imaging of white matter abnormalities (WMAs). Methods Multicentre retrospective cohort study 160 cCMV (103 symptomatic). A four-grade scoring system was applied to cranial ultrasonography acquired at ≤3 months. WMAs were categorised as multifocal or diffuse. Temporal-pole (TPWMAs) consisted swollen cystic...

<h3>BACKGROUND:</h3> High-flow nasal cannula (HFNC) is increasingly used to provide respiratory support in infants with bronchiolitis. The delivery of aerosol therapy through a jet nebulizer widely indicated despite its controversial efficacy and poor tolerability. <h3>METHODS:</h3> This randomized cross-over study aimed evaluate the comfort satisfaction using nebulization system integrated into HFNC compared standard practice face mask. COMFORT-Behavior (COMFORT-B) scale, visual analog...

Aim To investigate the circumstances surrounding end-of life decisions (EoL) of infants with hypoxic-ischaemic encephalopathy (HIE) and examine changes over a 10-year period. Methods Retrospective chart review all HIE who died during 2000–2004 2005–2009 in Level III Neonatal Intensive Care Unit Madrid, Spain. Results Of 70 HIE, 18 neonatal The mean age death was 64.4 ± 51 h. In 17 (94%), preceded by an EoL decision, four after withholding therapy (WH) 13 withdrawal (WDT). All WH were...

Cerebral oximetry using near-infrared spectroscopy (NIRS) provides continuous, noninvasive assessment of the degree hemoglobin saturation brain tissue. Previous studies suggest that high values regional cerebral tissue oxygen (rScO2) during first days in neonates with significant hypoxic-ischemic encephalopathy (HIE) are correlated an adverse neurological outcome. However, results not consistent among studies. To examine correlation rScO2 and their variability over time HIE severity,...
