Among genes present in all group A streptococci (GAS), those encoding M-fibril and T-pilus proteins display the highest levels of sequence diversity, giving rise to the two primary serological typing schemes historically used to define strain. A new genotyping scheme for the pilin adhesin and backbone genes is developed and, when combined with emm typing, provides an account of the global GAS strain population.
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.
Lateral violence, a group of behaviours directed towards people of the same group, is considered endemic among Aboriginal people. Behaviours include bullying, gossiping, isolation or exclusion of certain group members, and challenges to one’s Aboriginal identity. Lateral violence impacts all aspects of one’s life. Due to its pervasiveness, this qualitative study investigated strategies employed by Aboriginal people to deal with lateral violence.
In cystic fibrosis, gastrointestinal dysfunction and lower airway infection occur early and are independently associated with poorer outcomes in childhood. This study aimed to define the relationship between the microbiota at each niche during the first 2 years of life, its association with growth and airway inflammation, and explanatory features in the metabolome.

Invasive fungal disease (IFD) occurs less frequently during treatment for solid compared to hematological malignancies in children, and risk groups are poorly defined. Retrospective national multicenter cohort data (2004-2013) were analyzed to document prevalence, clinical characteristics, and microbiology of IFD.
This study explored mental health profiles in Australian school students using indicators of well-being (i.e., optimism, life satisfaction, and happiness) and psychological distress (i.e., sadness and worries). The sample included 75,757 students (ages 8-18 years) who completed the 2019 South Australian Wellbeing and Engagement Collection.
Recent studies report conflicting results regarding the relationship between labour epidural analgesia (LEA) in mothers and neurodevelopmental disorders in their offspring. We evaluated behavioural and neuropsychological test scores in children of mothers who used LEA.
Extensive research over the past 50 years has resulted in significant improvements in survival for patients diagnosed with leukemia. Despite this, a subgroup of patients harboring high-risk genetic alterations still suffer from poor outcomes. There is a desperate need for new treatments to improve survival, yet consistent failure exists in the translation of in vitro drug development to clinical application.
School-based nutrition education (NE) has an important role in promoting healthy eating habits and helping prevent chronic diseases – particularly among disadvantaged children and youth who are more likely to experience poor diet quality.
