The airway epithelium is the primary structural and functional airway barrier and orchestrates innate immunity. Some children may have underlying epithelial vulnerabilities that contribute to the pathogenesis of acute wheeze and asthma.

Children's development is dependent on a range of factors influencing their life course outcomes. Protective and challenging social and cultural determinants impact how Indigenous families support their children's developmental foundations. However, there is a lack of international evidence investigating Indigenous child development interventions.

Children with early-stage (pre-symptomatic) type 1 diabetes are currently identified primarily via research-based screening programmes in Australia. Once identified, families live with the knowledge that their child has an increased chance of developing symptomatic, lifelong, insulin-requiring type 1 diabetes but have no specific clinical pathway available to them in Western Australia for accessing tailored support or education. This project aimed to co-design a new clinical pathway to address this unmet need.

The capacity for children to self-regulate is an important developmental task of early childhood, with caregivers playing an integral role in self-regulation development. While caregivers' emotions and behaviors are known to impact child self-regulatory capacity, the impact of child self-regulation difficulties on parents is less understood. 

Patients with congenital heart disease (CHD) are identified in 1% of live births. Improved surgical intervention means many patients now survive to adulthood, the corollary of which is increased mortality in the over-65-year-old congenital heart disease population. In the clinic, genetic sequencing increasingly identifies novel genetic variants in genes related to CHD.

Carcinogenic effects of ultraviolet radiation (UVR) with reference to skin cancer are the basis of widely implemented recommendations to avoid sun exposure. Whether the benefits of "restrictive sun policies" outweigh their potential harms due to diminished beneficial effects of sunlight exposure remain a matter of controversy.  

Diarrhoea remains a leading cause of mortality among children under five years of age, with over 99 % of deaths occurring in low- and middle-income countries. Poor water quality, inadequate sanitation, poverty, undernutrition, and limited healthcare access contribute to this lingering problem, together with emerging environmental stressors driven by climate change.

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.

Malaria remains a leading cause of morbidity and mortality and is responsible for over 0.5 million annual deaths globally. During the first two decades of this century, scale-up of a range of tools was associated with significant reductions in malaria mortality in the primary risk group, young African children.

Perioperative anxiety is a common and distressing aspect of anaesthesia for many children, resulting in management challenges at the time of anaesthesia and potential physical and psychological adverse outcomes. We conducted this qualitative phenomenological study to explore the perspectives of children, parents and staff on perioperative anxiety in our institution. Planned recruitment was 20 each of children who had undergone elective anaesthesia, their parents and staff.
