RESUMO
BACKGROUND: Data on whether ultrasonography for the initial diagnostic imaging of forearm fractures in children and adolescents is noninferior to radiography for subsequent physical function of the arm are limited. METHODS: In this open-label, multicenter, noninferiority, randomized trial in Australia, we recruited participants 5 to 15 years of age who presented to the emergency department with an isolated distal forearm injury, without a clinically visible deformity, in whom further evaluation with imaging was indicated. Participants were randomly assigned to initially undergo point-of-care ultrasonography or radiography, and were then followed for 8 weeks. The primary outcome was physical function of the affected arm at 4 weeks as assessed with the use of the validated Pediatric Upper Extremity Short Patient-Reported Outcomes Measurement Information System (PROMIS) score (range, 8 to 40, with higher scores indicating better function); the noninferiority margin was 5 points. RESULTS: A total of 270 participants were enrolled, with outcomes for 262 participants (97%) available at 4 weeks (with a window of ±3 days) as prespecified. PROMIS scores at 4 weeks in the ultrasonography group were noninferior to those in the radiography group (mean, 36.4 and 36.3 points, respectively; mean difference, 0.1 point; 95% confidence interval [CI], -1.3 to 1.4). Intention-to-treat analyses (in 266 participants with primary outcome data recorded at any time) produced similar results (mean difference, 0.1 point; 95% CI, -1.3 to 1.4). No clinically important fractures were missed, and there were no between-group differences in the occurrence of adverse events. CONCLUSIONS: In children and adolescents with a distal forearm injury, the use of ultrasonography as the initial diagnostic imaging method was noninferior to radiography with regard to the outcome of physical function of the arm at 4 weeks.

STUDY OBJECTIVE: In patients aged 5 to 15 years with a clinically nondeformed distal forearm injury presenting to the emergency department (ED), we examined whether point-of-care ultrasound or radiographic imaging had better diagnostic accuracy, with the reference diagnosis determined by an expert panel review. METHODS: This multicenter, open-label, diagnostic randomized controlled trial was conducted in South East Queensland, Australia. Eligible patients were randomized to receive initial imaging through point-of-care ultrasound performed by an ED clinician or radiograph. Images were defined as "no," "buckle," or "other" fracture by the treating clinician. The primary outcome was the diagnostic accuracy of the treating clinician's interpretation compared against the reference standard diagnosis, which was determined retrospectively by an expert panel consisting of an emergency physician, pediatric radiologist, and pediatric orthopedic surgeon, who reviewed all imaging and follow-up. RESULTS: Two-hundred and seventy participants were enrolled, with 135 randomized to each initial imaging modality. There were 132 (97.8%) and 112 (83.0%) correctly diagnosed participants by ED clinicians in the point-of-care ultrasound and radiograph groups, respectively (absolute difference [AD]=14.8%; 95% confidence interval [CI] 8.0% to 21.6%; P<.001). Point-of-care ultrasound had better accuracy for participants with "buckle" fractures (AD=18.5%; 95% CI 7.1% to 29.8%) and "other" fractures (AD=17.1%; 95% CI 2.7% to 31.6%). No clinically important fractures were missed in either group. CONCLUSION: In children and adolescents presenting to the ED with a clinically nondeformed distal forearm injury, clinician-performed (acquired and interpreted) point-of-care ultrasound more accurately identified the correct diagnosis than clinician-interpreted radiographic imaging.

BACKGROUND: Morton's neuroma (MN) is a painful neuropathy resulting from a benign enlargement of the common plantar digital nerve that occurs commonly in the third webspace and, less often, in the second webspace of the foot. Symptoms include burning or shooting pain in the webspace that extends to the toes, or the sensation of walking on a pebble. These impact on weight-bearing activities and quality of life. OBJECTIVES: To assess the benefits and harms of interventions for MN. SEARCH METHODS: On 11 July 2022, we searched CENTRAL, CINAHL Plus EBSCOhost, ClinicalTrials.gov, Cochrane Neuromuscular Specialised Register, Embase Ovid, MEDLINE Ovid, and WHO ICTRP. We checked the bibliographies of identified randomised trials and systematic reviews and contacted trial authors as needed. SELECTION CRITERIA: We included all randomised, parallel-group trials (RCTs) of any intervention compared with placebo, control, or another intervention for MN. We included trials where allocation occurred at the level of the individual or the foot (clustered data). We included trials that confirmed MN through symptoms, a clinical test, and an ultrasound scan (USS) or magnetic resonance imaging (MRI). DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. We assessed bias using Cochrane's risk of bias 2 tool (RoB 2) and assessed the certainty of the evidence using the GRADE framework. MAIN RESULTS: We included six RCTs involving 373 participants with MN. We judged risk of bias as having 'some concerns' across most outcomes. No studies had a low risk of bias across all domains. Post-intervention time points reported were: three months to less than 12 months from baseline (nonsurgical outcomes), and 12 months or longer from baseline (surgical outcomes). The primary outcome was pain, and secondary outcomes were function, satisfaction or health-related quality of life (HRQoL), and adverse events (AE). Nonsurgical treatments Corticosteroid and local anaesthetic injection (CS+LA) versus local anaesthetic injection (LA) Two RCTs compared CS+LA versus LA. At three to six months: ⢠CS+LA may result in little to no difference in pain (mean difference (MD) -6.31 mm, 95% confidence interval (CI) -14.23 to 1.61; P = 0.12, I2 = 0%; 2 studies, 157 participants; low-certainty evidence). (Assessed via a pain visual analogue scale (VAS; 0 to 100 mm); a lower score indicated less pain.) ⢠CS+LA may result in little to no difference in function when compared with LA (standardised mean difference (SMD) -0.30, 95% CI -0.61 to 0.02; P = 0.06, I2 = 0%; 2 studies, 157 participants; low-certainty evidence). (Function was measured using: the American Orthopaedic Foot and Ankle Society Lesser Toe Metatarsophalangeal-lnterphalangeal Scale (AOFAS; 0 to 100 points) - we transformed the scale so that a lower score indicated improved function - and the Manchester Foot Pain and Disability Schedule (MFPDS; 0 to 100 points), where a lower score indicated improved function.) ⢠CS+LA probably results in little to no difference in HRQoL when compared to LA (MD 0.07, 95% CI -0.03 to 0.17; P = 0.19; 1 study, 122 participants; moderate-certainty evidence), and CS+LA may not increase satisfaction (risk ratio (RR) 1.08, 95% CI 0.63 to 1.85; P = 0.78; 1 study, 35 participants; low-certainty evidence). (Assessed using the EuroQol five dimension instrument (EQ-5D; 0-1 point); a higher score indicated improved HRQoL.) ⢠The evidence is very uncertain about the effects of CS+LA on AE when compared with LA (RR 9.84, 95% CI 1.28 to 75.56; P = 0.03, I2 = 0%; 2 studies, 157 participants; very low-certainty evidence). Adverse events for CS+LA included mild skin atrophy (3.9%), hypopigmentation of the skin (3.9%) and plantar fat pad atrophy (2.6%); no adverse events were observed with LA. Ultrasound-guided (UG) CS+LA versus non-ultrasound-guided (NUG) CS+LA Two RCTs compared UG CS+LA versus NUG CS+LA. At six months: ⢠UG CS+LA probably reduces pain when compared with NUG CS+LA (MD -15.01 mm, 95% CI -27.88 to -2.14; P = 0.02, I2 = 0%; 2 studies, 116 feet; moderate-certainty evidence). (Assessed with a pain VAS.) ⢠UG CS+LA probably increases function when compared with NUG CS+LA (SMD -0.47, 95% CI -0.84 to -0.10; P = 0.01, I2 = 0%; 2 studies, 116 feet; moderate-certainty evidence). We do not know of any established minimum clinical important difference (MCID) for the scales that assessed function, specifically, the MFPDS and the Manchester-Oxford Foot Questionnaire (MOXFQ; 0 to 100 points; a lower score indicated improved function.) ⢠UG CS+LA may increase satisfaction compared with NUG CS+LA (risk ratio (RR) 1.71, 95% CI 1.19 to 2.44; P = 0.003, I2 = 15%; 2 studies, 114 feet; low-certainty evidence). ⢠HRQoL was not measured. ⢠UG CS+LA may result in little to no difference in AE when compared with NUG CS+LA (RR 0.42, 95% CI 0.12 to 1.39; P = 0.15, I2 = 0%; 2 studies, 116 feet; low-certainty evidence). AE included depigmentation or fat atrophy for UG CS+LA (4.9%) and NUG CS+LA (12.7%). Surgical treatments Plantar incision neurectomy (PN) versus dorsal incision neurectomy (DN) One study compared PN versus DN. At 34 months (mean; range 28 to 42 months), PN may result in little to no difference for satisfaction (RR 1.06, 95% CI 0.87 to 1.28; P = 0.58; 1 study, 73 participants; low-certainty evidence), or for AE (RR 0.95, 95% CI 0.32 to 2.85; P = 0.93; 1 study, 75 participants; low-certainty evidence) compared with DN. AE for PN included hypertrophic scaring (11.4%), foreign body reaction (2.9%); AE for DN included missed nerve (2.5%), artery resected (2.5%), wound infection (2.5%), postoperative dehiscence (2.5%), deep vein thrombosis (2.5%) and reoperation with plantar incision due to intolerable pain (5%). The data reported for pain and function were not suitable for analysis. HRQoL was not measured. AUTHORS' CONCLUSIONS: Although there are many interventions for MN, few have been assessed in RCTs. There is low-certainty evidence that CS+LA may result in little to no difference in pain or function, and moderate-certainty evidence that UG CS+LA probably reduces pain and increases function for people with MN. Future trials should improve methodology to increase certainty of the evidence, and use optimal sample sizes to decrease imprecision.

BACKGROUND: Hospital-acquired pressure injuries (HAPIs) pose significant challenges in healthcare and cause increased patient suffering, longer hospital stays, and higher healthcare costs. Paediatric patients face unique risks, but evidence remains scarce. This study aimed to identify and describe HAPI admission incidence and severity predictors in a large Australian children's hospital. METHODS: This retrospective cohort study investigated all paediatric patients between January 2020 and December 2021 using a census approach. Demographic and clinical data including HAPI-related data were accessed from the incident monitoring and hospital administration databases. The incidence rate (per 1000 patient admissions) was calculated based on all admissions. Predictors of HAPI severity were identified using multivariable multinomial logistic regression. The study adhered to the STROBE guidelines for retrospective cohort studies. RESULTS: The HAPI incidence rate was 6.96 per 1000 patient admissions. Of the age groups, neonates had the highest HAPI incidence (15.5 per 1000 admissions). Critically ill children had the highest rate for admission location (12.8 per 1000 patient admissions). Most reported cases were stage I (64.2%). Age was associated with injury severity, with older paediatric patients more likely to develop higher-stage HAPIs. Additionally, Aboriginal and/or Torres Strait Islander patients had a higher HAPI severity risk. CONCLUSION: HAPI injuries in paediatric patients are unacceptably high. Prevention should be prioritized, and the quality of care improved in Australia and beyond. Further research is needed to develop targeted prevention strategies for these vulnerable populations. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This research emphasizes the need for standardized reporting, culturally sensitive care and tailored prevention strategies. IMPACT: The research has the potential to influence healthcare policies and practices, ultimately enhancing the quality of patient care. REPORTING METHOD: STROBE guidelines. NO PATIENT OR PUBLIC CONTRIBUTION: There was no patient or public contribution to the conduct of this study.
RESUMO
The association of air pollution and greenspace with respiratory pathogen acquisition and respiratory health was investigated in a community-based birth-cohort of 158 Australian children. Weekly nasal swabs and daily symptom-diaries were collected for 2-years, with annual reviews from ages 3-7-years. Annual exposure to fine-particulate-matter (PM2.5), nitrogen-dioxide (NO2), and normalised-difference-vegetation-index (NDVI) was estimated for pregnancy and the first 2-years-of-life. We examined rhinovirus, any respiratory virus, Streptococcus pneumoniae, Moraxella catarrhalis, and Haemophilus influenzae detections in the first 3-months-of-life, age at initial pathogen detection, wheezing in the first 2-years, and asthma at ages 5-7-years. Our findings suggest that higher NDVI was associated with fewer viral and M. catarrhalis detections in the first 3-months, while increased PM2.5 and NO2 were linked to earlier symptomatic rhinovirus and H. influenzae detections, respectively. However, no associations were observed with wheezing or asthma. Early-life exposure to air pollution and greenspace may influence early-life respiratory pathogen acquisition and illness. .

AIM: The aim of this study was to evaluate the construct validity of the Both Hands Assessment (BoHA) using activity of the upper limbs as detected by accelerometry in children with bilateral cerebral palsy (CP). METHODS: Observational study of children with CP (n = 44, n = 27 boys, aged 9.1 ± 1.6 years; Manual Ability Classification Scale I: n = 15, II: n = 22, III: n = 7) completing a BoHA assessment while wearing a triaxial accelerometer on each wrist. BoHA Each-Hand sub-scores, BoHA percentage difference between hands, BoHA Units, mean activity for each hand, mean activity asymmetry index and total mean activity were calculated. Linear regressions were used to analyze associations between measures. RESULTS: There were significant, positive associations between BoHA Units and total mean activity (B = 0.86, 95%CI: 0.32, 1.40), BoHA Percentage difference between hands and mean activity asymmetry index (B = 0.95, 95%CI: 0.75,1.15), and BoHA Each-Hand sub-score and mean activity for the non-dominant hand (B = 1.71, 95%CI: 1.16, 2.28), but not the dominant hand (B = 0.50, 95%CI: -0.45, 1.45). CONCLUSIONS: This study provides further evidence for the construct validity of the BoHA as a measure of upper limb performance. Wearable wrist sensors such as accelerometers capture and quantify gross upper limb movement in children with CP but cannot measure fine finger movements captured by the BoHA.

BACKGROUND: Endotracheal suction is used to maintain endotracheal tube patency. There is limited guidance to inform clinical practice for children with respiratory infections. OBJECTIVE: The objective of this study was to determine whether implementation of a paediatric endotracheal suction appropriate use guideline Paediatric AirWay Suction (PAWS) is associated with an increased use of appropriate and decreased use of inappropriate suction interventions. METHODS: A mixed-method, pre-implementation-post-implementation study was conducted between September 2021 and April 2022. Suction episodes in mechanically ventilated children with a respiratory infection were eligible. Using a structured approach, we implemented the PAWS guideline in a single paediatric intensive care unit. Evaluation included clinical (e.g., suction intervention appropriateness), implementation (e.g., acceptability), and cost outcomes (implementation costs). Associations between implementation of the PAWS guideline and appropriateness of endotracheal suction intervention use were investigated using generalised linear models. RESULTS: Data from 439 eligible suctions were included in the analysis. Following PAWS implementation, inappropriate endotracheal tube intervention use reduced from 99% to 58%, an absolute reduction (AR) of 41% (95% confidence interval [CI]: 25%, 56%). Reductions were most notable for open suction systems (AR: 48%; 95% CI: 30%, 65%), 0.9% sodium chloride use (AR: 23%; 95% CI: 8%, 38%) and presuction and postsuction manual bagging (38%; 95% CI: 16%, 60%, and 86%; 95% CI: 73%, 99%), respectively. Clinicians perceived PAWS as acceptable and suitable for use. CONCLUSIONS: Implementation of endotracheal tube suction appropriate use guidelines in a mixed paediatric intensive care unit was associated with a large reduction in inappropriate suction intervention use in paediatric patients with respiratory infections.

INTRODUCTION: First-insertion success rates for peripheral vascular access devices (PVADs) in patients with difficult venous access (DIVA) are low, which negatively affects staff workload, patient experience, and organizational cost. There is mixed evidence regarding the impact of a peripheral vascular access device with retractable coiled tip guidewire (GW; AccuCath™, BD) on the first-insertion success rate. The aim of this study is to investigate whether the use of long GW-PVADs, compared with standard PVADs, reduces the risk of first-time insertion failure, in patients admitted to emergency departments (EDs). METHODS AND ANALYSIS: A parallel-group, two-arm, randomized controlled trial will be carried out in two Australian EDs to compare long GW-PVADs (5.8 cm length) against standard care PVADs (short or long). Patients ≥18 years of age meeting DIVA criteria will be eligible for the trial. The sample size is 203 participants for each arm. Web-based central randomization will be used to ensure allocation concealment. Neither clinicians nor patients can be blinded to treatment allocation. Primary outcome is the first-insertion success rate. Secondary outcomes include the number of insertion attempts, time to insert PVAD, all-cause failure, dwell-time, patient-reported pain, serious adverse events, complications, subsequent vascular access devices required, patient satisfaction, staff satisfaction, and healthcare costs. Differences between the two groups will be analyzed using Cox proportional hazards regression. Cost-effectiveness analysis will also be conducted. Intention-to-treat analysis will be used. ETHICS AND DISSEMINATION: The study is approved by Metro South Ethics Committee (HREC/2022/QMS/82264) and Griffith University (2022/077). The findings will be published in a peer-reviewed journal. TRIAL REGISTRATION: ACTRN12622000299707.

BACKGROUND: Rotavirus vaccines have reduced effectiveness in high-mortality settings. Interference between enteric viruses and live-attenuated oral vaccine strains may be a factor. METHODS: In a birth cohort of healthy Australian infants, parents collected weekly stool samples. Three hundred eighty-one paired swabs collected within 10-days of RotaTeq vaccination from 140 infants were tested for 10 enteric viruses and RotaTeq strains. RESULTS: Collectively, both ribonucleic acid and deoxyribonucleic acid viruses were negatively associated with RotaTeq shedding (adjusted odds ratio = 0.29, 95% confidence interval = 0.14-0.58 and adjusted odds ratio = 0.30, 95% confidence interval = 0.11-0.78, respectively). CONCLUSIONS: Enteric viruses may interfere with RotaTeq replication in the gut and thus RotaTeq stool shedding.

BACKGROUND: A novel human parechovirus 3 Australian recombinant (HPeV3-AR) strain emerged in 2013 and coincided with biennial outbreaks of sepsis-like illnesses in infants. We evaluated the molecular evolution of the HPeV3-AR strain and its association with severe HPeV infections. METHODS: HPeV3-positive samples collected from hospitalized infants aged 5-252 days in 2 Australian states (2013-2020) and from a community-based birth cohort (2010-2014) were sequenced. Coding regions were used to conduct phylogenetic and evolutionary analyses. A recombinant-specific polymerase chain reaction was designed and utilized to screen all clinical and community HPeV3-positive samples. RESULTS: Complete coding regions of 54 cases were obtained, which showed the HPeV3-AR strain progressively evolving, particularly in the 3' end of the nonstructural genes. The HPeV3-AR strain was not detected in the community birth cohort until the initial outbreak in late 2013. High-throughput screening showed that most (>75%) hospitalized HPeV3 cases involved the AR strain in the first 3 clinical outbreaks, with declining prevalence in the 2019-2020 season. The AR strain was not statistically associated with increased clinical severity among hospitalized infants. CONCLUSIONS: HPeV3-AR was the dominant strain during the study period. Increased hospital admissions may have been from a temporary fitness advantage and/or increased virulence.

BACKGROUND: Sapovirus is an important cause of acute gastroenteritis (AGE) in young children. However, knowledge gaps remain in community settings. We investigated the epidemiology, disease characteristics, and healthcare use associated with sapovirus infections in Australian children during their first 2 years of life. METHODS: Children in the Brisbane-based Observational Research in Childhood Infectious Diseases birth cohort provided daily gastrointestinal symptoms (vomiting/loose stools), weekly stool swabs, and healthcare data until age 2 years. Swabs were batch-tested for sapovirus using real-time polymerase chain reaction assays. Incidence rates and estimates of associations were calculated. RESULTS: Overall, 158 children returned 11 124 swabs. There were 192 sapovirus infection episodes. The incidence rate in the first 2 years of life was 0.89 infections per child-year (95% confidence interval [CI], .76-1.05), and the symptomatic incidence rate was 0.26 episodes per child-year (95% CI, .17-.37). Age ≥6 months, the fall season, and childcare attendance increased disease incidence significantly. Fifty-four of the 180 (30%) infections with linked symptom diaries were symptomatic, with 72% recording vomiting and 48% diarrhea. Prior infection reduced risk of further infections (adjusted hazard ratio, 0.70 [95% CI, .54-.81]) in the study period. Viral loads were higher and viral shedding duration was longer in symptomatic than asymptomatic children. Twenty-three (43%) symptomatic episodes required healthcare, including 6 emergency department presentations and 2 hospitalizations. CONCLUSIONS: Sapovirus infections are common in Australian children aged 6-23 months. Efforts to reduce childhood AGE after the global rollout of rotavirus vaccines should include sapovirus where estimates of its incidence in communities will be crucial.

BACKGROUND: Traffic-related air pollution (TRAP) problems are unlikely to be solved in the short term, making it imperative to educate children on protective measures to mitigate the negative impact on their health. Children and their caregivers may hold differing views on wearing a face mask as a safeguard against air pollution. While many studies have focused on predicting children's health-protective behaviours against air pollution, few have explored the differences in perceptions between children and their caregivers. OBJECTIVES: To examine this, we conducted a study that compared the health beliefs of two generations and evaluated the factors that influence the use of masks by children to reduce air pollution exposure. METHODS: The study was conducted in 24 secondary schools and involved 8420 children aged 13-14 and their caregivers. We used a Health Belief Model (HBM)-based instrument containing 17-item self-administered health beliefs questionnaires to gather data. The results were analysed using hierarchical logistic regression to determine the probability of children frequently wearing masks to protect against TRAP. RESULTS: Our study showed both children and caregivers recognised that several factors could influence mask-wearing among children: discomfort or difficulty breathing while wearing a mask and forgetting to bring a mask when going outside; perceived threats of the poor quality of air and children's respiratory health problems; and cues to mask use (i.e., seeing most of their friends wearing facemasks and ease of finding masks in local stores). However, only children were significantly concerned with public perception of their appearance while wearing a mask. Females were more likely to wear masks, and caregivers with higher levels of education were more likely to encourage their children to wear masks. Children who commuted to schools by walking, biking, or motorbiking were also more accepting of mask-wearing than those who travelled by car or bus. CONCLUSIONS: Children and their caregivers hold different perceptions of wearing masks to protect against air pollution. Children are more susceptible to social judgements regarding their appearance when wearing a mask.

BACKGROUND: To determine the diagnostic accuracy of Hammersmith Neonatal Neurological Examination (HNNE) at 30-32 weeks postmenstrual age (PMA, 'Early') and term equivalent age (TEA) in infants born <31 weeks PMA to predict cognitive outcomes at 12 months corrected age (CA). METHODS: Prospective cohort study of 119 infants (73 males; median 28.4 weeks gestational age at birth) who underwent Early and TEA HNNE. At 12 months CA, 104 participants completed Bayley Scales of Infant and Toddler Development, 3rd Edition, (Bayley-III). Optimum cut-off points for each HNNE subscale were determined to establish diagnostic accuracy for predicting adverse cognitive outcomes on the Bayley-III Cognitive Composite Scale (≤85). RESULTS: The best diagnostic accuracy for HNNE total score at 30-32 weeks PMA predicting cognitive impairment occurred at cut-off ≤16.7 (sensitivity (Se) = 71%, specificity (Sp) = 51%). The Abnormal Signs subscale demonstrated the best balance of sensitivity/specificity combination (Se = 71%, Sp = 71%; cut-off ≤1.5). For HNNE at TEA, the total score at cut-off ≤24.5 had Se = 71% and Sp = 47% for predicting cognitive impairment. The Tone Patterns subscale demonstrated the strongest diagnostic accuracy at TEA (Se = 71%, Sp = 63%; cut-off ≤3). CONCLUSIONS: Early and TEA HNNE demonstrated moderate diagnostic accuracy for cognitive outcomes at 12-months CA in infants born <31 weeks gestational age. CLINICAL TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry; Trial Registration Number: ACTRN12613000280707; web address of trial: http://www.ANZCTR.org.au/ACTRN12613000280707.aspx . IMPACT: Early Hammersmith Neonatal Neurological Examination (HNNE) assessment at 30-32 weeks postmenstrual age has moderate diagnostic accuracy for cognitive outcomes at 12 months corrected age in infants born <31 weeks gestation. Early HNNE at 30-32 weeks has stronger predictive validity than HNNE at term equivalent age. Early HNNE may provide an early marker for risk-stratification to optimise the planning of post-discharge support and follow-up services for infants born preterm.

To determine human bocavirus-1 (HBoV1) infection characteristics in young Australian children. Data were from the Observational Research in Childhood Infectious Diseases (ORChID) study, a Brisbane, Australia-based birth cohort of healthy, term, newborns followed prospectively for 2 years. Parents recorded daily symptoms, maintained an illness-burden diary, and collected weekly nasal swabs, which were tested for 17 respiratory viruses, including HBoV1, by real-time polymerase chain reaction (PCR) assays. Main outcomes measured were infection incidence, risk factors, symptoms, and healthcare use. One hundred fifty-eight children in the ORChID cohort provided 11,126 weekly swabs, of which 157 swabs were HBoV1 positive involving 107 incident episodes. Co-detections were observed in 65/157 (41.4%) HBoV1-positive swabs (or 41/107 [38.3%] infection episodes), principally with rhinovirus. Shedding duration was 1 week in 64.5% of episodes. The incidence of HBoV1 infections in the first 2 years of life was 0.58 episodes per child-year (95% confidence interval [CI] 0.47-0.71), including 0.38 episodes per child-year (95% CI 0.30-0.49) associated with respiratory symptoms. Recurrent episodes occurred in 18/87 (20.7%) children following their primary infection. In the first 2 years of life, incidence of HBoV1 episodes increased with age, during winter and with childcare attendance. Overall, 64.2% of HBoV1 episodes were symptomatic, with 26.4% having healthcare contact. Viral load estimates were higher when children were symptomatic than when asymptomatic (mean difference = 3.4; 95% CI 1.0-5.7 PCR cycle threshold units). After age 6 months, HBoV1 is detected frequently in the first 2 years of life, especially during winter. Symptoms are usually mild and associated with higher viral loads.

BACKGROUND: Medicines are the most frequent health care intervention type; their safe use provides significant benefits, but inappropriate use can cause harm. Systemic primary care approaches can manage serious medication-related problems in a timely manner. OBJECTIVES: ACTMed (ACTivating primary care for MEDicine safety) uses information technology and financial incentives to encourage pharmacists to work more closely with general practitioners to reduce the risk of harm, improve patients' experience of care, streamline workflows, and increase the efficiency of medical care. METHODS AND ANALYSIS: The stepped wedge cluster randomised trial in 42 Queensland primary care practices will assess the effectiveness of the ACTMed intervention. The primary outcome will be the proportion of people at risk of serious medication-related problems - patients with atrial fibrillation, heart failure, cardiovascular disease, type 2 diabetes, or asthma or chronic obstructive pulmonary disease - who experience such problems. We will also estimate the cost per averted serious medication-related problem and the cost per averted potentially preventable medication-related hospitalisation. ETHICS APPROVAL: The University of Queensland Human Research Ethics Committee approved the pilot (2021/HE002189) and trial phases of the ACTMed study (2022/HE002136). Access to Patron data was granted by the Patron Data Governance Committee (PAT052ACTMed). Access to linked hospitalisations and deaths data are subject to Public Health Act approval (pending). DISSEMINATION OF FINDINGS: A comprehensive dissemination plan will be co-developed by the researchers, the ACTMed steering committee and consumer advisory group, project partners, and trial site representatives. Aboriginal and Torres Strait Islander communities will be supported in leading community-level dissemination. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (pilot: ACTRN12622000595718; 21 April 2022; full trial: ACTRN12622000574741; 14 April 2022).

OBJECTIVE: Lack of recognition of asthma in childhood results in unmet asthma treatment needs and leads to the risk of sub-optimal respiratory health. The present study assessed the prevalence of asthmatic under-recognition in middle school children in Vietnam. METHODS: We conducted a school-based survey among 15,112 Vietnamese children. Most of them are aged from 13 to 14. Schools and students were recruited using multi-stage sampling. Respiratory symptoms were collected via self-report using a standardized tool from the International Study of Asthma and Allergies in Childhood. Under-recognition of asthma was defined as a presence of at least one asthma-like symptom but a negative response to having ever asthma. Associations were investigated using logistic regression. RESULTS: Prevalence of asthma-like symptoms was 27.3% and prevalence of physician-diagnosed asthma was 8.5%. Over 80% of symptomatic children were not diagnosed with asthma. Under-recognition of asthma was found more in girls (adjusted odds ratio; aOR = 1.75; 95%CI: 1.54 to 1.98). CONCLUSIONS: Asthma is significantly under-recognized in Vietnamese middle-school children. Urgent action is required to improve the recognition of asthma in Vietnam.

AIM: To describe the development of social function in children with cerebral palsy (CP) classified in all levels of the Communication Function Classification System (CFCS). METHOD: This prospective, longitudinal population-based cohort study recruited children with CP born in Queensland, Australia. Social functioning was measured using the Pediatric Evaluation of Disability Inventory (PEDI) social function domain at 2 years, 2 years 6 months, 3 years, 4 years, and 5 years, and the PEDI Computer Adaptive Test (PEDI-CAT) social/cognitive domain at 8 to 12 years. RESULTS: Seventy-four children provided 356 observations. PEDI-CAT social/cognitive scaled scores at 8 to 12 years were (mean [SD] n) CFCS level I, 68.6 (2.7) 45; CFCS level II, 64.0 (3.4) 10; CFCS level III, 63.5 (3.7) 4; CFCS level IV, 56.8 (5.0) 9; CFCS level V, 47.2 (5.8) 6. Scores within expected range for age (not less than 2 SD below mean) at 8 to 12 years were achieved by 35 (78%) children in CFCS level I and four (14%) in CFCS levels II to V. Forty-nine per cent of children scored at least two standard deviations below the population mean on a proxy measure of fluid intelligence. Intellectual impairment was associated with lower PEDI-CAT social/cognitive scaled scores in univariable analysis (ß = -8.3, 95% confidence interval - 10.91 to -5.63; p < 0.001) but had a smaller effect when modelled together with CFCS. INTERPRETATION: Social function attained by 8 to 12 years of age was strongly related to level of communication function (CFCS). The small number of children classified in CFCS levels II to V necessitates caution when viewing these individual CFCS level trajectories. WHAT THIS PAPER ADDS: There is a strong relation between social functioning and Communication Function Classification System (CFCS) levels. At 8 to 12 years, 35 out of 45 children in CFCS level I met social functioning age expectations. Twenty-five out of 29 in CFCS levels II to V had social functioning below that expected for age. CFCS and age were more strongly associated with development of social functioning than Gross Motor Function Classification System or Manual Ability Classification System and age.

AIM: To evaluate the predictive validity of the Hammersmith Neonatal Neurological Examination (HNNE) performed early (at 32 weeks postmenstrual age) and at term-equivalent age (TEA) for 12-month motor outcomes in infants born very preterm. METHOD: This was a diagnostic study using data from a prospective birth cohort. A total of 104 infants born preterm at less than 31 weeks gestational age (males n = 61; mean = 28 weeks 1 day [SD 1 week 6 days], range 23 weeks 1 day-30 weeks 6 days) underwent HNNE early and at TEA, which were scored by comparison with term data. Motor outcomes at 12 months corrected age were determined using the Bayley Scales of Infant and Toddler Development, Third Edition (scores ≤85). Cut-off points were determined using receiver operating characteristic curves. RESULTS: Sixteen (15%) infants born preterm had motor impairment at 12 months corrected age. The HNNE total score cut-off points with the best combination of sensitivity and specificity at early and TEA assessments were 15.2 or lower (sensitivity 77%, 95% confidence interval [CI] = 46%-95%; specificity 74%, 95% CI = 63%-83%) and 23.5 or lower (sensitivity 67%, 95% CI = 38%-88%; specificity 66%, 95% CI = 54%-76%) respectively. The most predictive subscale at the early assessment was reflexes (sensitivity 86%, 95% CI = 57%-98%; specificity 62%, 95% CI = 51%-72%; cut-off point ≤3); at TEA, it was spontaneous movements (sensitivity 73%, 95% CI = 45%-92%; specificity 60%, 95% CI = 48%-70%; cut-off point ≤2). INTERPRETATION: The HNNE provides moderate predictive accuracy for motor outcome at 12 months corrected age in infants born very preterm. Although modest at both time points, early assessment had stronger predictive ability for motor outcomes than TEA when scored using term data, highlighting the value of performing the HNNE earlier in the neonatal period. Performing HNNE earlier may assist risk stratification when planning follow-up services.

AIM: This study aimed to identify early clinical biomarkers from birth to 16 weeks corrected age to predict typical outcome and developmental delay in infants born very preterm or with very low birthweight. METHOD: A prospective cohort of infants on the Sunshine Coast, Australia, was assessed using the Premie-Neuro Examination, the General Movement Assessment (GMA), the Alberta Infant Motor Scale, and the Infant Sensory Profile 2. At 24 months corrected age, delay was identified using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) and Neurosensory Motor Developmental Assessment (NSMDA). RESULTS: One hundred and four infants were recruited; 79 completed outcome assessments (43 females, 36 males; mean gestational age 30 weeks [SD 1 week 6 days], mean birthweight 1346 g [SD 323]). The incidence of developmental delay (motor or cognitive) was 6.3%. Suboptimal quality of fidgety general movements (temporal organization) at 16 weeks corrected age demonstrated the best predictive accuracy (Bayley-III motor: sensitivity 100% [95% confidence interval {CI} 3-100], specificity 75% [95% CI 63-84], area under the curve [AUC] 0.87); Bayley-III cognitive: sensitivity 100% [95% CI 3-100], specificity 75% [95% CI 64-84], AUC 0.88); NSMDA motor: sensitivity 100% [95% CI 40-100], specificity 81% [95% CI 70-90], AUC 0.91 [95% CI 0.86-0.95]). GMA trajectories that combined abnormal writhing general movements at 4 to 5 weeks corrected age with suboptimal quality of fidgety movement at 16 weeks corrected age were strongly predictive of developmental delay, superior to all other clinical tools, and perinatal and demographic variables investigated (p = 0.01, Akaike information criterion method 18.79 [score corrected for small sample size], accounting for 93% of the cumulative weight). INTERPRETATION: Only the GMA had sufficient predictive validity to act as a biomarker for both conditions: typical outcome and developmental delay (motor or cognitive). GMA trajectories that assessed both writhing general movements at 4 to 5 weeks corrected age and quality of fidgety movement at 16 weeks corrected age predicted adverse neurodevelopmental outcome, accurately differentiating between infants with typical outcomes and those at increased risk for motor or cognitive delay.

BACKGROUND: Few Australasian autologous stem cell transplantation (ASCT) programmes perform ASCT in the private sector. Relatively little is known about ASCT outcomes in the private sector, which varies in care delivery models to the public system. AIMS: To investigate transplantation activity and survival outcomes at Icon Cancer Centre's Brisbane-based private clinical and laboratory ASCT programme over a 23-year period. METHODS: Retrospective, observational study of all adults who underwent ASCT at Icon between 1996 and 2018. Main outcome measures were transplant activity, overall survival (OS) and 100-day and 1-year transplant-related mortality (TRM). Outcomes were benchmarked against the Australasian Bone Marrow Transplant Recipient Registry (ABMTRR). RESULTS: Between 1996 and 2018, 1676 ASCT were performed in 1454 patients. From 2010 to 2018, ASCT performed at Icon contributed 40% of all South East Queensland ASCT. In the past 5 years, 21% of Icon's patients were aged ≥70 years, compared with 5% across Australasia. For the entire cohort, 100-day and 1-year TRM was 1.1% and 1.7%, respectively, while for those aged ≥70 years, it was 2.0% and 3.1%. For ASCT performed between 2014 and 2018, 100-day and 1-year TRM was 0.8% and 1.4%, which was half the TRM rates reported by the ABMTRR. The 10-year post-transplant OS at Icon was higher than the ABMTRR data, across all disease subtypes. CONCLUSION: We report excellent OS and low TRM, demonstrating the critical role of the private sector in the administration of this highly complex therapy. The Icon ASCT programme is the largest ASCT contributor in Queensland. It is inclusive of patients aged ≥70 years, demonstrating low and acceptable TRM.
