From hype to hope: Considerations in conducting robust microbiome scienceMicrobiome science has been one of the most exciting and rapidly evolving research fields in the past two decades. Breakthroughs in technologies including DNA sequencing have meant that the trillions of microbes (particularly bacteria) inhabiting human biological niches (particularly the gut) can be profiled and analysed in exquisite detail.

Patient and Process Outcomes among Pediatric Patients Undergoing Appendectomy during the COVID-19 Pandemic: An International Retrospective Cohort StudyCOVID-19 forced healthcare systems to make unprecedented changes in clinical care processes. The authors hypothesized that the COVID-19 pandemic adversely impacted timely access to care, perioperative processes, and clinical outcomes for pediatric patients undergoing primary appendectomy.

Ca-EDTA restores the activity of ceftazidime-avibactam or aztreonam against carbapenemase-producing Klebsiella pneumoniae infectionsDeveloping an effective therapy to overcome carbapenemase-positive Klebsiella pneumoniae (CPKp) is an important therapeutic challenge that must be addressed urgently. Here, we explored a Ca-EDTA combination with aztreonam or ceftazidime-avibactam in vitro and in vivo against diverse CPKp clinical isolates.

PKC activation promotes maturation of cord blood T cells towards a Th1 IFN-γ propensityA significant number of babies present transiently with low protein kinase C zeta (PKCζ) levels in cord blood T cells, associated with reduced ability to transition from a neonatal Th2 to a mature Th1 cytokine bias, leading to a higher risk of developing allergic sensitisation, compared to neonates whose T cells have 'normal' PKCζ levels. However, the importance of PKCζ signalling in regulating their differentiation from a Th2 to a Th1 cytokine phenotype propensity remains undefined.

Safety and Tolerability of V114 Pneumococcal Vaccine in Infants: A Phase 3 StudyDisease caused by Streptococcus pneumoniae is associated with considerable morbidity and mortality in children. Pneumococcal conjugate vaccines are well tolerated and effective at reducing pneumococcal disease caused by vaccine serotypes. VAXNEUVANCE (V114) is a 15-valent PCV containing 13 serotypes in Prevnar 13, plus serotypes 22F and 33F. This large phase 3 study evaluated safety and tolerability of V114 in infants.

Editorial: The relationship between puberty and immune-driven diseaseThe way the immune system operates differs between males and females. This is due to both differential expression of immune-related genes from the sex chromosomes as well as the immune modulatory properties of sex hormones. Together, these effects contribute to a skewed prevalence of disease and disease course between males and females, including allergic-, infectious-, autoimmune-, and cancerous disease.

A Research Translation, Implementation and Impact Strategy for the Australian Healthy Environments and Lives (HEAL) Research NetworkHealthy Environments And Lives (HEAL) is the Australian national research network established to support improvements to health, the Australian health system, and the environment in response to the unfolding climate crisis. The HEAL Network comprises researchers, community members and organisations, policymakers, practitioners, service providers, and other stakeholders from diverse backgrounds and sectors.

Substrate-dependent metabolomic signatures of myeloperoxidase activity in airway epithelial cells: Implications for early cystic fibrosis lung diseaseMyeloperoxidase is released by neutrophils in inflamed tissues. MPO oxidizes chloride, bromide, and thiocyanate to produce hypochlorous acid, hypobromous acid, and hypothiocyanous acid, respectively. These oxidants are toxic to pathogens, but may also react with host cells to elicit biological activity and potential toxicity. In cystic fibrosis and related diseases, increased neutrophil inflammation leads to increased airway MPO and airway epithelial cell exposure to its oxidants.

COVID-19 in Western Australia: ‘The last straw’ and hopes for a ‘new normal’ for parents of children with long-term conditionsChildren with long-term conditions are vulnerable due to the treatments required for their conditions. Since the start of the coronavirus disease 2019 (COVID-19) pandemic, Western Australians experienced restrictions that changed daily life activities but were able to return to some of their previous routines due to the restrictions.
