Polymicrobial sepsis is associated with worse patient outcomes than monomicrobial sepsis. Routinely used culture-dependent microbiological diagnostic techniques have low sensitivity, often leading to missed identification of all causative organisms.
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.
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.
Very preterm infants have a marked innate inflammatory response at the time of late-onset sepsis
Sildenafil is used to treat pulmonary hypertension in neonatal intensive care unit (NICU) settings. As multiple intravenous (IV) medications are co-administered in NICU settings, we sought to investigate the physicochemical compatibility of sildenafil with a range of IV drugs.
Neonatal sepsis is a major cause of childhood mortality. Limited diagnostic tools and mechanistic insights have hampered our abilities to develop prophylactic or therapeutic interventions. Biomarkers in human neonatal sepsis have been repeatedly identified as associated with dysregulation of angiopoietin signaling and altered arachidonic acid metabolism.
Neonatal sepsis-induced cardiovascular dysfunction includes impaired myocardial function (which may be systolic and/or diastolic) and vasoregulatory failure (which may lead to vasodilation or vasoconstriction). The haemodynamic response in neonatal sepsis may therefore be hyperdynamic or hypodynamic, and the underlying pathophysiological mechanisms are heterogenous.
Skin care for very and extremely preterm infant is an important and previously underappreciated topic. Coconut oil skin care for preterm infants is a promising option, but several important questions remain including the theoretical potential for allergic sensitization.
Sepsis is one of the leading causes of neonatal mortality. There is heterogeneity in the outcomes measured and reported in studies of neonatal sepsis. To address this challenge, a core outcome set (COS) for research on neonatal sepsis was needed.
Viral infections are associated with significant morbidity and mortality in neonates. The COVID-19 pandemic led to changes in viral epidemiology in Western Australia. The impact on patients in neonatal intensive care is uncertain.
