High-Fidelity simulation-based program improves flow state scale in the perinatal team.

Background: We aimed to evaluate the degree of realism and involvement, stress management and awareness of performance improvement in practitioners taking part in high fidelity simulation (HFS) training program for delivery room (DR) management, by means of a self-report test such as flow state scale (FSS).

Methods: This is an observational pretest-test study. Between March 2016 and May 2019, fourty-three practitioners (physicians, midwives, nurses) grouped in multidisciplinary teams were admitted to our training High Fidelity Simulation center.

The application of bathophenanthroline for the determination of free iron in parallel with hROS in microdialysis samples.

Background: Free, non-protein bound, Fe(II), which can catalyse the formation of the toxic highly-reactive oxygen species (hROS), has been implicated in several neurodegenerative conditions. The determination of free Fe(II) and Fe(III) in samples obtained from microdialysis experiments has been limited by the small amounts of sample available.

New Method: This work describes the development of a HPLC, with absorbance detection, method, based on the complexation of Fe(II) with bathophenanthroline disulfonate (BS), which allows a complete extracellular iron analysis with the small sample amounts that are available from in vivo microdialysis in rat brain.

Monitoring the effectiveness of hypothermia in perinatal asphyxia infants by urinary S100B levels.

Background Perinatal asphyxia is a major cause of mortality and morbidity in neonates: The aim of the present study was to investigate, by means of longitudinal assessment of urinary S100B, the effectiveness of hypothermia, in infants complicated by perinatal asphyxia and hypoxic-ischemic encephalopathy. Methods We performed a retrospective case-control study in 108 asphyxiated infants, admitted to nine tertiary departments for neonatal intensive care from January 2004 to July 2017, of whom 54 underwent hypothermia treatment and 54 did not. The concentrations of S100B protein in urine were measured using an immunoluminometric assay at first urination and 4, 8, 12, 16, 20, 24, 48, 72, 96, 108 and 120 h after birth.

Comparison of three non-invasive ventilation strategies (NSIPPV/BiPAP/NCPAP) for RDS in VLBW infants.

Background: Non-invasive ventilation (NIV) significantly changed the management of respiratory distress syndrome (RDS) in preterm infants. Further perspectives for neonatologists regard the assessment of different NIV strategies in terms of availability, effectiveness, and failure.

Objective: The aim of the present study is to evaluate the effectiveness of three different NIV strategies: nasal continuous positive airway pressure (N-CPAP), nasal synchronized intermittent positive pressure ventilation (N-SIPPV), and nasal bilevel-CPAP (BiPAP), as first intention treatment for RDS in very low birth-weight infants (VLBW).

Continuous monitoring of highly reactive oxygen radicals during in vivo microdialysis.

Background: Terephthalate (TA(2-)), which reacts with highly reactive oxygen species (hROS) to form the fluorophor 2-hydroxy terephthalic acid (OH-TA) with a high selectivity, has been used for determining hROS formation during in vivo microdialysis. Previously this involved collecting fractions of the microdialysate and determining the OH-TA formed after HPLC (the batch method).

New Method: This work reports the development and validation of a procedure for continuously determining hROS formation during microdialysis.
