Persistent respiratory bacterial infections are a clinical burden in several chronic inflammatory airway diseases and are often associated with neutrophil infiltration into the lungs. Following recruitment, dysregulated neutrophil effector functions such as increased granule release and formation of neutrophil extracellular traps (NETs) result in damage to airway tissue, contributing to the progression of lung disease.
Bacteriophage (phage) propagation has traditionally relied on bacterial culture media containing animal-derived ingredients; however, safety concerns with animal-derived materials for production of phages for therapeutic use limit their acceptability. We compared animal-free and traditional media formulations, and evaluated effects on phage yield, bactericidal activity, and genomic characteristics, hypothesizing no significant differences would be observed.
Functional studies of how early-life interventions shape the airway microbiome remain scarce. Here, we performed metagenomic sequencing of 704 longitudinal nasal swabs from infants with and without cystic fibrosis (CF) to construct and characterize a non-redundant gene atlas of the infant nasal microbiome. We aimed to determine how the nasal microbiome is perturbed by early therapies, as CF is commonly treated with inhaled hypertonic saline to improve mucociliary clearance.
Childhood emotional abuse (CEA) has been linked to response-focused emotion regulation in adulthood. However, the underlying mechanisms remain unexplored. This pre-registered study examined whether shame mediates the association between CEA history and aversive cognitive perseveration (ACP), including brooding rumination, experiential avoidance and emotional non-acceptance, in adulthood.
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.
Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus
Unhealthy outdoor food advertising is strongly linked to poor diet, highlighting the need for policies. Western Australian (WA) local governments can restrict advertising on their owned infrastructure through their Public Health Plans, but limited policy action has occurred.
Hand burns are a key criterion for immediate referral to tertiary burn centres in Australia, New Zealand, and internationally, yet few studies have examined how paediatric burn epidemiology, surgical management, and length of stay differ according to the extent of hand involvement.
Streptococcus pyogenes (Group A Streptococcus, Strep A) is a Gram-positive bacterium and one of the most significant global bacterial pathogens, with disproportionate disease burden affecting low and middle-income countries. Despite substantial mortality and immune sequelae caused by Strep A, no licensed vaccines exist, and correlates of protection remain unestablished.
When doctors working within healthcare systems under pressure perpetrate, witness, or fail to prevent acts that contradict their own moral or ethical values and expectations, it can lead to moral distress or moral injury. This can result from active behaviour and from purposeful inactive behaviour. It is a growing and critical concern, representing significant distress that extends far beyond traditional concepts such as burnout. This article discusses moral injury in clinical and academic medicine and actively gives suggestions to prevent and address moral injury.
