Clinical predictors for surfactant retreatment in preterm infants with respiratory distress syndrome: the results of a pooled analysis.

Background: The issue of retreatment with surfactant of infants with respiratory distress syndrome (RDS) has been poorly investigated. Our aim was to identify possible clinical predictors of the need for multiple doses of surfactant in a large cohort of very preterm infants.

Methods: Data were analyzed from three previous studies on infants born between 25 and 31 weeks of gestation with RDS who were treated with surfactant.

Resuscitation With Placental Circulation Intact Compared With Cord Milking: A Randomized Clinical Trial.

Importance: Among preterm newborns undergoing resuscitation, delayed cord clamping for 60 seconds is associated with reduced mortality compared with early clamping. However, the effects of longer durations of cord clamping with respiratory support are unknown.

Objective: To determine whether resuscitating preterm newborns while keeping the placental circulation intact and clamping the cord after a long delay would improve outcomes compared with umbilical cord milking.

Neonatal Sequential Organ Failure Assessment Score Predicts Respiratory Outcomes in Preterm Newborns with Late-Onset Sepsis: A Retrospective Study.

Introduction: Neonatal sequential organ failure assessment (nSOFA) score predicts mortality in preterm newborns. The aim of the study was to assess whether nSOFA score could predict respiratory outcomes in preterm infants with late-onset sepsis (LOS).

Methods: This retrospective, observational, single-center study enrolled infants with gestational age <32 weeks born between January 2016 and June 2023 who experienced an episode of LOS during NICU stay.

Splanchnic and cerebral oxygenation during cyclic phototherapy in preterm infants with hyperbilirubinemia.

Cyclic phototherapy (cPT) can achieve a reduction in total serum bilirubin comparable to that achieved with standard continuous PT in preterm infants. Our aim was to assess the effect of cPT on splanchnic (rSOS) and cerebral (rSOC) oxygenation measured by near-infrared spectroscopy (NIRS). We prospectively studied 16 infants with a gestational age of 25-34 weeks with hyperbilirubinemia requiring PT.

Late-Onset Sepsis among Extremely Preterm Infants of 24-28 Weeks Gestation: An International Comparison in 10 High-Income Countries.

Introduction: Despite advances in neonatal care, late-onset sepsis remains an important cause of preventable morbidity and mortality. Neonatal late-onset sepsis rates have decreased in some countries, while in others they have not. Our objective was to compare trends in late-onset sepsis rates in 9 population-based networks from 10 countries and to assess the associated mortality within 7 days of late-onset sepsis.

SARS-CoV-2 perinatal transmission and neonatal outcomes across four different waves of COVID-19 pandemic: A nationwide prospective cohort study from the Italian Society of Neonatology.

Objectives: To describe how SARS-CoV-2 infection at the time of delivery affected maternal and neonatal outcomes across four major waves of the COVID-19 pandemic in Italy.

Methods: This is a large, prospective, nationwide cohort study collecting maternal and neonatal data in case of maternal peripartum SARS-CoV-2 infection between February 2020 and March 2022. Data were stratified across the four observed pandemic waves.

Prognostic accuracy of Neonatal SOFA score versus SIRS criteria in preterm infants with late-onset sepsis.

Neonatal SOFA score was reported as an accurate predictor of mortality while the prognostic accuracy of SIRS criteria is unknown. The aim was to compare neonatal SOFA and SIRS criteria for the prediction of late onset sepsis-related mortality in preterm newborns. Newborns ≤ 32 weeks with late onset sepsis were retrospectively studied.

New Antimicrobials for the Treatment of Neonatal Sepsis Caused by Multi-Drug-Resistant Bacteria: A Systematic Review.

Background: Infections by multi-drug-resistant (MDR) organisms are sharply increasing in newborns worldwide. In low and middle-income countries, a disproportionate amount of neonatal sepsis caused by MDR Gram negatives was recently reported. Newborns with infections by MDR organisms with limited treatment options may benefit from novel antimicrobials.

Cardiac Hypertrophy Associated with Insulin Therapy in Extremely Preterm Infants.

Background: In the neonatal period, cardiac hypertrophy (CH) has been commonly associated with hyperinsulinemic pathologies, and the first case of CH in an extremely preterm infant treated with insulin infusion has recently been reported. To confirm this association, we report a case series of patients who developed CH after insulin therapy.

Methods: Infants with gestational age < 30 weeks and birth weight < 1500 g, born from November 2017 to June 2022, were studied if they developed hyperglycemia requiring treatment with insulin and had echocardiographic diagnosis of CH.

Presepsin for the Diagnosis of Neonatal Early-Onset Sepsis: A Systematic Review and Meta-analysis.

Importance: Neonatal early-onset sepsis (EOS) is a severe disease, particularly in preterm infants. Timely diagnosis can be challenging owing to unspecific presentation and questionable performance of the common markers of infection. Presepsin was recently proven to be a promising biomarker for the diagnosis of EOS.

Presepsin (Soluble CD14 Subtype) as an Early Marker of Neonatal Sepsis and Septic Shock: A Prospective Diagnostic Trial.

In the context of suspected neonatal sepsis, early diagnosis and stratification of patients according to clinical severity is not yet effectively achieved. In this diagnostic trial, we aimed to assess the accuracy of presepsin (PSEP) for the diagnosis and early stratification of supposedly septic neonates. PSEP, C-reactive protein (CRP), and procalcitonin (PCT) were assessed at the onset of sepsis suspicion (T0), every 12-24 h for the first 48 h (T1-T4), and at the end of antibiotic therapy (T5).

Intravenous paracetamol in comparison with ibuprofen for the treatment of patent ductus arteriosus in preterm infants: a randomized controlled trial.

Our aim was to assess the efficacy and safety of intravenous (i.v.) paracetamol vs.

Lung recruitment before surfactant administration in extremely preterm neonates with respiratory distress syndrome (IN-REC-SUR-E): a randomised, unblinded, controlled trial.

Background: The importance of lung recruitment before surfactant administration has been shown in animal studies. Well designed trials in preterm infants are absent. We aimed to examine whether the application of a recruitment manoeuvre just before surfactant administration, followed by rapid extubation (intubate-recruit-surfactant-extubate [IN-REC-SUR-E]), decreased the need for mechanical ventilation during the first 72 h of life compared with no recruitment manoeuvre (ie, intubate-surfactant-extubate [IN-SUR-E]).

Reference ranges of Presepsin in preterm infants in the first 48 h of life: A multicenter observational study.

Background And Objectives: Despite low incidence of early-onset sepsis, the majority of preterm newborns receive early antibiotic prophylaxis. Our aim was to assess reference ranges of Presepsin during the first 48 h of life in preterm infants and to evaluate the possible influence of neonatal and maternal factors on its values.

Methods: This observational study consecutively enrolled newborns ≤ 32 weeks of GA at 0-6 h of life.

Lung Ultrasound for the Differential Diagnosis of Respiratory Distress in Neonates.

Background: Respiratory distress (RD) is the most common neonatal illness. Lung ultrasound (LUS) is a technique previously tested in neonatal studies on RD, but literature regarding its routine clinical applicability is still lacking.

Objective: To assess the concordance between LUS performed by neonatologists with different training levels and chest X-ray (CXR) for the diagnosis of RD in newborns during the first 24 h of life.

Changes in bilirubin in infants with hypoxic-ischemic encephalopathy.

Antioxidant properties of bilirubin have been reported in many studies. We hypothesized that bilirubin might be involved in neuroprotection mechanisms against oxidative stress in infants with hypoxic-ischemic encephalopathy (HIE) and that total serum bilirubin (TSB) might increase in these patients. We retrospectively studied infants with gestational age ≥ 35 weeks and birth weight ≥ 1800 g who were admitted to the neonatal intensive care unit (NICU) with a diagnosis of moderate-to-severe HIE and received or did not receive therapeutic hypothermia.

Sepsis and Oxidative Stress in the Newborn: From Pathogenesis to Novel Therapeutic Targets.

Sepsis is at present one of the leading causes of morbidity and mortality in the neonatal population. Together with inflammation, oxidative stress is involved in detrimental pathways activated during neonatal sepsis, eventually leading to organ dysfunction and death. The redox cascade during sepsis is mainly initiated by IL-6 and IL-8 stimulation in newborns and includes multiple noxious processes, as direct cell damage induced by reactive oxygen species, activation of gene expression leading to amplification of inflammation and oxidative stress, and impairment of mitochondrial function.

Bilirubin and oxidative stress in term and preterm infants.

Hyperbilirubinemia is the most frequent clinical problem neonatologists must deal with during the newborn period. It has been suggested that bilirubin is involved in the balance between antioxidant and pro-oxidant agents due to its antioxidant properties. However, the relevance of these effects in vivo in term and preterm infants is still debated.

Effect on cerebral oxygenation of paracetamol for patent ductus arteriosus in preterm infants.

Unlabelled: Paracetamol seems to have similar success rates compared with indomethacin and ibuprofen in closing patent ductus arteriosus (PDA) in preterm infants, but with a better safety profile. The aim of our study was to evaluate the possible effects of paracetamol on cerebral oxygenation and cerebral blood flow velocity (CBFV). Infants with gestational age < 32 weeks with hemodynamically significant PDA (hsPDA) were prospectively studied by near infrared spectroscopy (NIRS) after the first dose of paracetamol (15 mg/kg) or ibuprofen (10 mg/kg).

Unexpected episodes of cyanosis in late preterm and term neonates prompted admission to a neonatal care unit.

Background: We studied late preterm and term infants who were admitted to our neonatal care unit in a tertiary hospital for unexpected episodes of cyanosis that occurred during rooming-in for evaluation of their frequency, most frequent associated diseases, and documentation of the diagnostic clinical approach.

Methods: We carried out a retrospective study of infants with a gestational age ≥35 weeks who were admitted from the nursery with the diagnosis of cyanosis from January 2009 to December 2016. Exclusion criteria were the occurrence of acrocyanosis and the diagnosis of sudden unexpected postnatal collapse (SUPC).

Red blood cell transfusions can induce proinflammatory cytokines in preterm infants.

Background: The risk of developing red blood cell (RBC) transfusion-associated necrotizing enterocolitis (TANEC) in preterm infants has recently been emphasized. Our aim was to assess changes in cytokine serum levels after RBC transfusions in a cohort of very preterm infants to evaluate their possible proinflammatory effect.

Study Design And Methods: We carried out a prospective observational study.
