Angiogenesis-associated pathways play critical roles in neonatal sepsis outcomesNeonatal 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.

Thoracic Society of Australia and New Zealand position statement: The safe clinical use of sputum induction for bio-sampling of the lower airways in children and adultsSputum induction is widely used in clinical settings for collection of biological samples from the lower airways. However, in recent years sputum induction has been associated with serious adverse events and even death. This position statement was commissioned by the Thoracic Society of Australia and New Zealand to address major adverse events of two deaths associated with sputum induction that have occurred in Australia in 2021, and outlines best practice for the safe use of sputum induction.

OMIP-100: A flow cytometry panel to investigate human neutrophil subsetsThis 14-color, 13-antibody optimized multicolor immunofluorescence panel (OMIP) was designed for deep profiling of neutrophil subsets in various types of human samples to contextualize neutrophil plasticity in a range of healthy and diseased states. Markers present in the OMIP allow the profiling of neutrophil subsets associated with ontogeny, migration, phagocytosis capacity, granule release, and immune modulation.

Impaired interferon response in plasmacytoid dendritic cells from children with persistent wheezeImpaired interferon response and allergic sensitization may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells play a key role in antiviral immunity as critical producers of type I interferons.

Novel intranasal phage-CaEDTA-ceftazidime/avibactam triple combination therapy demonstrates remarkable efficacy in treating Pseudomonas aeruginosa lung infectionGiven the rise of multidrug-resistant (MDR) Pseudomonas aeruginosa infections, alternative treatments are needed. Anti-pseudomonal phage therapy shows promise, but its clinical application is limited due to the development of resistance and a lack of biofilm penetration.

Stability Considerations for Bacteriophages in Liquid Formulations Designed for NebulizationPulmonary bacterial infections present a significant health risk to those with chronic respiratory diseases including cystic fibrosis and chronic-obstructive pulmonary disease. With the emergence of antimicrobial resistance, novel therapeutics are desperately needed to combat the emergence of resistant superbugs.

COVID-19 monitoring with sparse sampling of sewered and non-sewered wastewater in urban and rural communitiesEquitable SARS-CoV-2 surveillance in low-resource communities lacking centralized sewers is critical as wastewater-based epidemiology (WBE) progresses. However, large-scale studies on SARS-CoV-2 detection in wastewater from low-and middle-income countries is limited because of economic and technical reasons.

Airway macrophages display decreased expression of receptors mediating and regulating scavenging in early cystic fibrosis lung diseaseCystic fibrosis (CF) airway disease is characterized by chronic inflammation, featuring neutrophil influx to the lumen. Airway macrophages (AMs) can promote both inflammation and resolution, and are thus critical to maintaining and restoring homeostasis. CF AM functions, specifically scavenging activity and resolution of inflammation, have been shown to be impaired, yet underlying processes remain unknown.

Defining the pediatric response to SARS-CoV-2 variantsThe global population has been severely affected by the coronavirus disease 2019 (COVID-19) pandemic, however, with older age identified as a risk factor, children have been underprioritized. This article discusses the factors contributing to the less severe response observed in children following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including, differing viral entry receptor expression and immune responses.

Respiratory Health Effects of In Vivo Sub-Chronic Diesel and Biodiesel Exhaust ExposureBiodiesel, which can be made from a variety of natural oils, is currently promoted as a sustainable, healthier replacement for commercial mineral diesel despite little experimental data supporting this. The aim of our research was to investigate the health impacts of exposure to exhaust generated by the combustion of diesel and two different biodiesels.
