Retinopathy of prematurity and placental histopathology findings: A retrospective cohort study

Retinopathy of prematurity (ROP) is a biphasic vaso-proliferative disease that has the potential to cause blindness. In addition to prematurity and hyperoxia, perinatal infection and inflammation have been reported to play a critical role in the pathogenesis of ROP. The aim of this study was to assess the association between placental inflammation and the severity of ROP.

Outcomes to 5 years of outborn versus inborn infants <32 weeks in Western Australia: A cohort study of infants born between 2005 and 2018

We compared mortality and morbidity of inborn versus outborn very preterm infants <32 weeks' gestation in Western Australia (WA) between 2005 and 2018

Composition of early life leukocyte populations in preterm infants with and without late-onset sepsis

Composition of leukocyte populations in the first month of life remains incompletely characterised, particularly in preterm infants who go on to develop late-onset sepsis (LOS). The aim of the study was to characterise and compare leukocyte populations in preterm infants with and without LOS during the first month of life.

Look Who's Talking: Host and Pathogen Drivers of Staphylococcus epidermidis Virulence in Neonatal Sepsis

Preterm infants are at increased risk for invasive neonatal bacterial infections. S. epidermidis, a ubiquitous skin commensal, is a major cause of late-onset neonatal sepsis, particularly in high-resource settings. The vulnerability of preterm infants to serious bacterial infections is commonly attributed to their distinct and developing immune system.

Impaired Cytokine Responses to Live Staphylococcus epidermidis in Preterm Infants Precede Gram-positive, Late-onset Sepsis

Late-onset sepsis (LOS) with Staphylococcus epidermidis is common in preterm infants, but the immunological mechanisms underlying heightened susceptibility are poorly understood. Our aim is to characterize the ontogeny of cytokine responses to live S. epidermidis in preterm infants with and without subsequent Gram-positive LOS.

Editorial: Immunity in Compromised Newborns

Plasma secretory phospholipase A2 as an early marker for late-onset sepsis in preterm infants—a pilot study

Preterm infants are particularly susceptible to bacterial late-onset sepsis (LOS). Diagnosis by blood culture and inflammatory markers have sub-optimal sensitivity and specificity and prolonged reporting times. There is an urgent need for more rapid, accurate adjunctive diagnostics in LOS to improve management and minimise antibiotic exposure.

RSV prophylaxis use in high-risk infants in Western Australia, 2002-2013: a record linkage cohort study

The monoclonal antibody, palivizumab is licensed for use in high-risk infants to prevent severe illness caused by respiratory syncytial virus (RSV). The level of its use and compliance with current jurisdictional guidelines which were amended in 2010, is unknown.

Lactoferrin Expression Is Not Associated with Late-Onset Sepsis in Very Preterm Infants

Preterm infants are at a high risk of developing late-onset sepsis (LOS). Lactoferrin is one of the most abundant endogenous antimicrobial proteins expressed in breast milk, stools, and blood, and a candidate for preventive intervention. Large clinical trials have recently investigated whether enteral supplementation with bovine lactoferrin reduces LOS.

Whole blood transcriptional responses of very preterm infants during late-onset sepsis

Blood responses in very preterm infants with LOS are characterised by altered host immune responses that appear to reflect unbalanced immuno-metabolic homeostasis

Plasma cytokine profiles in very preterm infants with late-onset sepsis

Very preterm infants have a marked innate inflammatory response at the time of late-onset sepsis

Effectiveness of Palivizumab against Respiratory Syncytial Virus: Cohort and Case Series Analysis

Palivizumab appeared effective for reducing virologically confirmed respiratory syncytial virus in this high-risk cohort
