Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years

Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult. 

Trajectories of prematurity-associated lung disease: lifelong lung health

Preterm birth is increasingly recognised as adversely influencing lifelong lung function. This Series paper on prematurity-associated lung disease reviews studies reporting longitudinal lung function measurements in individuals who were born preterm. Evidence suggests that preterm birth alters lung function trajectories from early life onwards, with implications for future respiratory morbidity. We propose that this population needs rigorous follow up that should include systematic monitoring of lung function across the lifespan, starting in childhood.

An infant nasal microbial gene atlas uncovers intervention-driven microbiome shifts and salt-resistant pathogen expansion

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.

Pediatric Bronchiectasis Action Management Plan to Improve Clinical Outcomes: A Randomized Controlled Trial

Managing bronchiectasis exacerbations is a priority for patients, parents, and caregivers of children with bronchiectasis. However, evidence-based strategies among the pediatric population remain limited.

What goes up must come down: dynamics of type 1 interferon signaling across the lifespan

Type 1 interferons (T1IFNs) are typically expressed in low concentrations under homeostatic conditions, but upon pathogenic insult or perturbation of the pathway, these critical immune signaling molecules can become either protectors from or drivers of pathology. While essential for initiating antiviral defense and modulating inflammation, dysregulation of T1IFN signaling can contribute to immunopathology, making it and its associated pathways prime targets for immune evasion and disruption by pathogens. 

Marked Variation in Paediatric Problematic Severe Asthma Services Across Australia and New Zealand

Asthma affects > 10% of children in Australia and New Zealand (NZ), with up to 5% of those having severe disease, presenting a management challenge. We aimed to survey tertiary paediatric respiratory services across Australia and NZ using a custom-designed questionnaire, to conduct a cross-sectional observational study of the numbers of children with problematic severe asthma seen, the number treated with biologic therapy, outpatient clinic/multidisciplinary team services available, investigations and tools routinely used and approaches utilised for transition to adult care.

Climate change policies fail to protect child health

National policies are essential for countries to adapt to the negative health impacts of climate change. Children are disproportionately affected by these impacts and must be at the heart of adaptation policies to address their vulnerabilities. Adaptation commitments worldwide are integrated into national adaptation plans, nationally determined contributions, national communications, and other multisectoral policies. We aimed to evaluate how effectively national climate change policies worldwide plan to protect child health, considering a range of determinants for successful child-health adaptation.

Phage cocktail amikacin combination as a potential therapy for bacteremia associated with carbapenemase producing colistin resistant Klebsiella pneumoniae

The increasing occurrence of hospital-associated infections, particularly bacteremia, caused by extensively drug-resistant (XDR) carbapenemase-producing colistin-resistant Klebsiella pneumoniae highlights a critical requirement to discover new therapeutic alternatives. Bacteriophages having host-specific bacteriolytic effects are promising alternatives for combating these pathogens. 

Does lung function in preschoolers help to predict asthma in later life?

The earliest respiratory function assessments, within or close to the neonatal period, consistently show correlations with lung function and with the development of asthma into adulthood. Measurements of lung function in infancy reflect the in utero period of lung development, and if early enough, show little influence of postnatal environmental exposures. 

Preterm lung disease: not just for neonatologists

Improvements in neonatal critical care have resulted in more people than ever reaching adulthood after being born prematurely. At the same time, it is becoming clearer that preterm birth can increase the risk of respiratory disease throughout a person’s lifetime. Awareness that a patient was born preterm can enable early specialist assessment and intervention when there is any concern about lung health.
