Implementation of negative pressure for acute pediatric burns (INPREP): A stepped-wedge cluster randomized controlled trial protocol.

Background: Acute application of adjunctive negative pressure wound therapy (NPWT) significantly improves time to re-epithelialization in pediatric burn patients. This adjunctive treatment has not yet been broadly or routinely adopted as a standard primary burns dressing strategy. The Implementation of Negative PRessurE for acute Pediatric burns (INPREP) trial will implement and evaluate the impact of adjunctive NPWT in parallel with co-designed implementation strategies and resources across four major pediatric hospitals.

Does injury type influence patient preference, response rates, and data completeness for online or telephone follow-up following injury?

Introduction: Collecting patient-reported outcomes in a systematic fashion is important to understand recovery trajectories and compare performance between different services and fields of care. These outcomes can be collected through a variety of means, but studies comparing different follow-up methods in patients with a variety of injury types are scarce. This study aimed to compare follow-up data from three injury registries to quantify patient preference for telephone versus online follow-up, determine factors associated with choosing online follow-up, and compare response rates based on the patient's preferred follow-up method.

Rhinovirus as a Driver of Airway T-Cell Dynamics in Children with Severe Asthma.

Severe asthma in children is notoriously difficult to treat, and its immunopathogenesis is complex. In particular, the contribution of T cells and relationships to anti-viral immunity, remain enigmatic. Here, we coupled deep phenotyping with machine learning methods to resolve the dynamics of T cells in the diseased lower airways, and examined rhinovirus (RV) as a driver.

Feasibility of collecting long-term patient-reported outcome data in burns patients using a centralised approach.

Background: Collecting patient-reported outcome measures (PROMs) has been a longstanding priority for the Burns Registry of Australia and New Zealand (BRANZ). An earlier pilot of hospital-led PROM collection encountered low participation rates and high loss to follow-up, indicating consideration for an alternative model was warranted.

Aims: To establish the feasibility of implementing centralised long-term PROM collection within the BRANZ.

A Novel Use of Embryonic Gut Organoid Culture to Investigate Duodenal Atresia.

Background: The cause of duodenal atresia (DA) is not known. Tandler's "solid cord" hypothesis conflicts with current biological evidence. In humans, a genetic aetiology is supported by the association with Trisomy 21.

A novel syndrome of silent rhinovirus-associated bronchoalveolitis in children with recurrent wheeze.

Background: Rhinovirus (RV) infections trigger wheeze episodes in children. Thus, understanding of the lung inflammatory response to RV in children with wheeze is important.

Objectives: This study sought to examine the associations of RV on bronchoalveolar lavage (BAL) granulocyte patterns and biomarkers of inflammation with age in children with treatment-refractory, recurrent wheeze (n = 616).

Pulmonary MRI with hyperpolarized xenon-129 demonstrates novel alterations in gas transfer across the air-blood barrier in asthma.

Background: Individuals with asthma can vary widely in clinical presentation, severity, and pathobiology. Hyperpolarized xenon-129 (Xe129) MRI is a novel imaging method to provide 3-D mapping of both ventilation and gas exchange in the human lung.

Purpose: To evaluate the functional changes in adults with asthma as compared to healthy controls using Xe129 MRI.

Developing a core outcome set for the health outcomes for children and adults with congenital oesophageal atresia and/or tracheo-oesophageal fistula: OCELOT task group study protocol.

Introduction: Heterogeneity in reported outcomes of infants with oesophageal atresia (OA) with or without tracheo-oesophageal fistula (TOF) prevents effective data pooling. Core outcome sets (COS) have been developed for many conditions to standardise outcome reporting, facilitate meta-analysis and improve the relevance of research for patients and families. Our aim is to develop an internationally-agreed, comprehensive COS for OA-TOF, relevant from birth through to transition and adulthood.

Trampoline Park Injury Trends.

Objectives: Trampolines are an important cause of childhood injury and focus of injury prevention. Understanding and prevention of trampoline park injury is constrained by inadequate exposure data to estimate the at-risk population. This study aimed to measure trampoline park injury incidence and time trends using industry data.

Grazing management impacts on ecosystem services under contrasting climatic conditions in Texas and North Dakota.

Grazing management is an important factor affecting the delivery of ecosystem services at the watershed scale. Moreover, characterizing the impacts of climate variation on water resources is essential in managing rangelands. In this study, the effects of alternative grazing management scenarios on provisioning, regulating, and supporting services were assessed in two watersheds with contrasting climates; the Lower Prairie Dog Town Fork Red River (LPDTFR) Watershed in North Texas and the Apple Watershed in South Dakota.

Craniofacial anomalies in a murine model of heterozygous fibroblast growth factor 10 gene mutation.

Objective: Dysregulation of Fibroblast Growth Factor 10 (FGF10), a member of the family of Fibroblast Growth Factor (FGF) proteins, has been implicated in craniofacial and dental anomalies, including craniosynostosis, cleft palate, and Lacrimo-Auriculo-Dento-Digital Syndrome. The aim of this murine study was to assess the craniofacial and dental phenotypes associated with a heterozygous FGF10 gene (FGF10 ) mutation at skeletal maturity.

Methods: Skulls of 40 skeletally mature mice, comprising two genotypes (heterozygous FGF10 mutation, n = 22; wildtype, n = 18) and two sexes (male, n = 23; female, n = 17), were subjected to micro-computed tomography.

Hyperpolarized Xenon-129: A New Tool to Assess Pulmonary Physiology in Patients with Pulmonary Fibrosis.

Purpose: The existing tools to quantify lung function in interstitial lung diseases have significant limitations. Lung MRI imaging using inhaled hyperpolarized xenon-129 gas (Xe) as a contrast agent is a new technology for measuring regional lung physiology. We sought to assess the utility of the Xe MRI in detecting impaired lung physiology in usual interstitial pneumonia (UIP).

Workflow Improvement of Electronic Health Record Usage in a Tertiary Pediatric Burns Clinic.

Background: As a high patient-throughput clinic, the Royal Children's Hospital's multidisciplinary burns clinic's efficiency of clinic workflow and streamlined patient assessment is crucial. The clinic has been using a customized "burns assessment tool" (BAT) as part of its integrated electronic health record (EHR) since 2016.

Objectives: The aim was to assess the usage patterns of the BAT at baseline, followed by re-evaluation following interventions to improve efficiency and utilization of the BAT.

Playground injury prevention: the need for consistent and national implementation of Australian safety standards.

Objectives: Hospitalisation rates for injury, including at playgrounds, have not changed in the past decade. There are nine Australian Standards specific to playgrounds. The impact (if any) of these standards on playground injury resulting in hospitalisation is unknown.
