Mapping Lung Hematopoietic Progenitors: Developmental Kinetics and Response to Influenza A InfectionThe bone marrow is a specialised niche responsible for the maintenance of hematopoietic stem and progenitor cells during homeostasis and inflammation. Recent studies however have extended this essential role to the extramedullary and extravascular lung microenvironment. Here, we provide further evidence for a reservoir of hematopoietic stem and progenitor cells within the lung from embryonic day 18.5 until adulthood.

Determinants of lung function development from birth to age 5 years: an interrupted time series analysis of a South African birth cohortEarly life is a key period that determines long-term health. Lung development in childhood predicts lung function attained in adulthood and morbidity and mortality across the life course. We aimed to assess the effect of early-life lower respiratory tract infection (LRTI) and associated risk factors on lung development from birth to school age in a South African birth cohort.

How climate change degrades child health: A systematic review and meta-analysisChildren are more vulnerable than adults to climate-related health threats, but reviews examining how climate change affects human health have been mainly descriptive and lack an assessment of the magnitude of health effects children face. This is the first systematic review and meta-analysis that identifies which climate-health relationships pose the greatest threats to children.

Signal-correction errors in the EasyOne Pro LAB multiple-breath washout device significantly impact outcomes in children and adultsMultiple-breath washout (MBW) is an established technique to assess functional residual capacity (FRC) and ventilation inhomogeneity in the lung. Indirect calculation of nitrogen concentration requires accurate measurement of gas concentrations.

Associations between natural blue and green space and preschool children's movement behavioursNatural outdoor environments provide important settings for children to engage in physical activity. It is unclear if these relationships also exist in preschool aged children. We examined associations between amount and type of neighbourhood vegetation and blue space, proximity to the beach and preschooler's device-measured movement behaviours.

“That's not fair on my kid”: Carers' perspectives on sport participation and experiences for children in out-of-home careChildren in out-of-home care participate in less organised sport than children from other household structures, potentially reducing opportunities for improvements in social, developmental, and health outcomes. Despite this, little is known about barriers and facilitators of sport participation for children in care. We aimed to explore carers' perspectives on the influences on children in care's participation and experiences in organised sport.

Developmental trends in young children’s device-measured physical activity and sedentary behaviourKnowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls.

Ethnicity and anthropometric deficits in children: A cross-sectional analysis of national survey data from 18 countries in sub-Saharan AfricaChild anthropometric deficits remain a major public health problem in Sub-Saharan Africa (SSA) and are a key target of the UN Sustainable Development Goals (SDGs). The SDGs recommend disaggregation of health indicators by ethnic group. However, few studies have assessed how ethnicity is associated with anthropometric deficits across SSA.

Prenatal Origins of Obstructive Airway Disease: Starting on the Wrong Trajectory?From the results of well-performed population health studies, we now have excellent data demonstrating that deficits in adult lung function may be present early in life, possibly as a result of developmental disorders, incurring a lifelong risk of obstructive airway diseases such as asthma and chronic obstructive pulmonary disease.

Plasma Cortisol Levels in Infants With Respiratory Distress During Different Phases of Neonatal Transport: A Pilot Prospective Observational Before-After StudyThe transport of sick newborn infants with respiratory distress leads to unwanted stress at time of physiological instability. There is dearth of studies to evaluate these stress levels. This pilot prospective observational before-after study aimed to evaluate the plasma cortisol levels (as surrogate marker of stress) in infants with respiratory distress during different phases of neonatal transport.
