Impact on cerebral hemodynamics of the use of volume guarantee combined with high frequency oscillatory ventilation in a neonatal animal respiratory distress model.

Unlabelled: High-frequency oscillatory ventilation (HFOV) is an alternative to conventional mechanical ventilation (CMV). Recently, the use of volume guarantee (VG) combined with HFOV has been suggested as a safe strategy capable of reducing the damage induced by ventilation in immature lungs. However, the possible impact of this new ventilation technique on cerebral hemodynamics is unknown.

Serologic evolution and follow-up to IgG antibodies of infants born to mothers with gestational COVID.

Background: It is known that SARS-CoV-2 antibodies from pregnant women with SARS-CoV-2 infection during pregnancy cross the placenta but the duration and the protective effect of these antibodies in infants is scarce.

Methods: This prospective study included mothers with SARS-COV-2 infection during pregnancy and their infants from April 2020 to March 2021. IgG antibodies to SARS-CoV-2 spike protein were performed on women and infants at birth and at two and six months during follow-up.

Microwave-assisted autohydrolysis of avocado seed for the recovery of antioxidant phenolics and glucose.

This study describes the valorization of avocado seed (AS) within a green biorefinery concept using microwave-assisted autohydrolysis. After the treatment at temperatures of 150-230 °C for 5 min, the resulting solid and liquor were characterized. The temperature of 220 °C led to the simultaneous optimal values of antioxidant phenolics/flavonoids (42.

Chylothorax in newborns after cardiac surgery: a rare complication?

Unlabelled: The aim of this study was to analyze patients diagnosed with chylothorax after congenital heart disease surgery among a cohort of neonatal patients, comparing the evolution, complications, and prognosis after surgery of patients who were and were not diagnosed with chylothorax, and to analyze possible risk factors that may predict the appearance of chylothorax in this population. Retrospective and observational study included all neonates (less than 30 days since birth) who underwent congenital heart disease surgery in a level III neonatal intensive care department. We included infants born between January 2014 and December 2019.

Microwave-assisted extraction of hemicellulosic oligosaccharides and phenolics from Robinia pseudoacacia wood.

Microwave-assisted autohydrolysis is an environmentally friendly intensification technology that permits the selective solubilization of hemicelluloses in form of oligosaccharides in a short time and with low energy consumption. The purpose of this work was to evaluate the suitability of microwave-assisted autohydrolysis to produce oligosaccharides and phenolics with potential prebiotic and antioxidant activities from Robinia pseudoacacia wood. The influence of treatment time (0-30 min) and temperature (200-230 °C) on oligosaccharide production was studied and conditions of 230 °C and 0.

Lung Ultrasound Scores Progress Differently in Extreme and Very Preterm Infants after Birth: A Multicentre Prospective Study.

Introduction: The lung ultrasound score (LUS) has been suggested to predict moderate-severe bronchopulmonary dysplasia (msBPD) in preterm infants. We aimed to assess LUS evolution after birth in preterm infants and the effect of gestational age.

Methods: This multicentre prospective observational study was performed with newborns born before 33 weeks of gestation.

Neonatal pneumothoraces with atypical location: the role of lung ultrasound.

Unlabelled: Neonatal pneumothorax (NP) is a potentially life-threatening condition. Lung ultrasound (LUS) has shown higher sensitivity and specificity in diagnosis compared to x-rays, but evidence regarding its usefulness in complex NP is lacking. We report four neonates suffering from cardiac or esophageal malformations who developed lateral and/or posterior pneumothoraces, in which LUS helped, making NP diagnosis and management easier and faster.

Microwave hydrothermal processing of the invasive macroalgae Sargassum muticum within a green biorefinery scheme.

This study deals with the multiproduct valorization of the invasive macroalgae Sargassum muticum within a green biorefinery concept using microwave hydrothermal treatment. Temperatures of 160 and 180 °C for 0-60 min (severities 1.62-3.

Lung ultrasound in preterm infants with respiratory distress: experience in a neonatal intensive care unit.

Lung ultrasound (LUS) has been described as a useful tool in early prognosis of several respiratory diseases of the newborn, especially preterm infant newborns (PTNB) with respiratory distress syndrome (RDS), but still, it is not a standard of care in many neonatal units. We have conducted a descriptive, prospective study in a tertiary neonatal unit during 1 year. PTNB less than 35 weeks with respiratory distress at birth on non-invasive ventilation were recruited.

New Strategies of Pulmonary Protection of Preterm Infants in the Delivery Room with the Respiratory Function Monitoring.

Objective: To investigate if the use of a visible respiratory function monitor (RFM) to use lower tidal volumes (Vts) during positive pressure ventilation (PPV) in the delivery room (DR) reduces the need of surfactant administration and invasive mechanical ventilation during the first 72 hours after birth of preterm infants <32 weeks' gestational age (GA).

Study Design: Infants <32 weeks' GA ( = 106) requiring noninvasive PPV were monitored with a RFM at birth and randomized to visible ( = 54) or masked ( = 52) display on RFM. Pulmonary data were recorded during the first 10 minutes after birth.
