Background: Developmental Dysplasia of the Hip (DDH) describes a spectrum of abnormalities that impact the normal function of the joint. These abnormalities are detectable during infancy using physical assessment, universal ultrasound, or a combination of both. In Australia, child health nurses predominantly screen for this disease using physical assessment. The aim of this study was to determine if child health nurses can accurately screen for DDH using physical assessment. Methods: This Australian study estimated the accuracy and utility of child health nurses using physical assessment to screen for DDH by comparing it to a handheld ultrasound device. Results: This study (N = 44) concluded that using a point prevalence study design, child health nurses in Australia are unable to accurately assess for DDH in infants using physical assessment; overall, clinicians had 50.5% sensitivity (95% CI, 15.7 to 84.3), a specificity of 75.0% (95% CI, 57.8 to 87.9), and 71.3% accuracy (95% CI, 55.6 to 83.9). Conclusion: This study suggests that child health nurses cannot screen for DDH using physical assessment. Understanding education, experience and what assessments are used suggests that the utility of nurses performing DDH screening requires further investigation. [ABSTRACT FROM AUTHOR]

Objective: Low acuity presentations (LAPs) contribute to large numbers of ED presentations and carry numerous consequences. The present study sought to improve the understanding of regional infant LAPs by analysing temporal patterns of presentation, discharge diagnoses and potential predictive factors. Methods: This retrospective observational study examined ED presentations among children less than 12 months old (infants) to the Royal Prince Alfred Hospital between 2017 and 2019. Descriptive statistics were used to identify temporal patterns of presentation and common discharge diagnoses among LAPs. Multivariable logistic regression was used to determine the association between early life, demographic and perinatal factors and low acuity presenters. Results: Of 6881 infant ED presentations, 19.8% were LAPs, occurring disproportionately on weekdays (82.2%) and during hours of 08.00–17.00 (69.9%). Respiratory tract infections and gastrointestinal complaints were most common overall, though non‐allergic rash, feeding difficulties, eczema and developmental concerns contributed substantially among LAPs. Socio‐economic status (SES) (odds ratio [OR] 1.71), overseas maternal nationality (OR 1.25) and Medicare ineligible maternal financial class (OR 0.49) were associated with low acuity presenters. Low appearance, pulse, grimace, activity and respiration score (OR 3.53), low SES (OR 3.26), complicated delivery (OR 1.64), maternal multiparity (OR 0.50), maternal partner presence (OR 0.40) and obstetric complications (OR 0.37) were associated with repeat, multi‐low acuity presenters (multi‐LAPs). Conclusion: A substantial minority of infant ED presentations are LAPs. Targeted interventions may benefit from focusing on families with a background of socioeconomic disadvantage, social isolation, cultural and linguistic diversity and perinatal complications, with a view to strengthening engagement with community‐based services among these groups.

An international taskforce of clinician-scientists was formed by specialty groups of World Physiotherapy – International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) & International Organisation of Physiotherapists in Paediatrics (IOPTP) – to develop evidence-based practice position statements directing physiotherapists clinical reasoning for the safe and effective use of spinal manipulation and mobilisation for paediatric populations (<18 years) with varied musculoskeletal or non-musculoskeletal conditions. A three-stage guideline process using validated methodology was completed: 1. Literature review stage (one scoping review, two reviews exploring psychometric properties); 2. Delphi stage (one 3-Round expert Delphi survey); and 3. Refinement stage (evidence-to-decision summative analysis, position statement development, evidence gap map analyses, and multilayer review processes). Evidence-based practice position statements were developed to guide the appropriate use of spinal manipulation and mobilisation for paediatric populations. All were predicated on clinicians using biopsychosocial clinical reasoning to determine when the intervention is appropriate. 1. It is not recommended to perform: • Spinal manipulation and mobilisation on infants. • Cervical and lumbar spine manipulation on children. •Spinal manipulation and mobilisation on infants, children, and adolescents for non-musculoskeletal paediatric conditions including asthma, attention deficit hyperactivity disorder, autism spectrum disorder, breastfeeding difficulties, cerebral palsy, infantile colic, nocturnal enuresis, and otitis media. 2. It may be appropriate to treat musculoskeletal conditions including spinal mobility impairments associated with neck-back pain and neck pain with headache utilising: • Spinal mobilisation and manipulation on adolescents; • Spinal mobilisation on children; or • Thoracic manipulation on children for neck-back pain only. 3. No high certainty evidence to recommend these interventions was available. Reports of mild to severe harms exist; however, risk rates could not be determined. Specific directives to guide physiotherapists' clinical reasoning on the appropriate use of spinal manipulation or mobilisation were identified. Future research should focus on trials for priority conditions (neck-back pain) in children and adolescents, psychometric properties of key outcome measures, knowledge translation, and harms.

There are few short, validated tools to assess young children's obesity‐related dietary behaviours, limiting the rapid screening of dietary behaviours in research and practice‐based early obesity prevention. This study aimed to develop and assess the reliability and validity of a caregiver‐reported short dietary questionnaire to rapidly assess obesity‐related dietary behaviours in children aged 6 months to 5 years. The Early Prevention of Obesity in Childhood Dietary Questionnaire (EPOCH‐DQ) was developed using a rigorous process to determine content and structural validity. Three age‐appropriate versions were developed for (1) infants, aged 6–12 months, (2) toddlers, aged 1–2.9 years and (3) pre‐schoolers, aged 3–5 years. The questionnaire (7–15 items) measures dietary behaviours, including diet risk from non‐core food and beverage intake, diet quality from vegetable frequency, bread type and infant feeding practices. Test–retest reliability was assessed from repeated administrations 1 week apart (n = 126). Internal consistency, concurrent validity (against a comparison questionnaire, the InFANT Food Frequency Questionnaire), construct validity and interpretability were assessed (n = 209). Most scores were highly correlated and significantly associated (p < 0.05) for validity (rs: 0.45–0.89, percentage agreement 68%–100%) and reliability (intraclass correlation coefficient: 0.61–0.99) for diet risk, diet quality and feeding practice items. The EPOCH‐DQ shows acceptable validity and reliability for screening of obesity‐related behaviours of children under 5 years of age. The short length and, thus, low participant burden of the EPOCH‐DQ allows for potential applications in various settings. Future testing of the EPOCH‐DQ should evaluate culturally and socio‐economically diverse populations and establish the predictive validity and sensitivity to detect change. Key messages: Accurate measurement of obesity‐related dietary behaviours is essential for the evaluation of early obesity prevention programmes and monitoring population trends.The 7–15 item Early Prevention of Obesity in Childhood Dietary Questionnaire (EPOCH‐DQ) was shown to have acceptable validity and reliability for assessing obesity‐related behaviours of children aged 6 months to 5 years of age.The short length and thus low participant burden of the EPOCH‐DQ allows for potential applications in various settings, including research, population health monitoring and use by health professionals.Future testing of the EPOCH‐DQ should include evaluation across culturally and socio‐economically diverse populations and determine the predictive validity and sensitivity to detect change of the EPOCH‐DQ.

Background: Here, we report new prevalence and temporal stability data for child attachment and parental caregiving behaviour, from infancy (1 year) to preschool (4 years). Methods: Attachment (SSP) and caregiving data (MBQS) were from observations of parents and their infants and preschoolers, who represent the third generation of participants within an Australian longitudinal cohort. Results: At 1 year (n = 314 dyads) and at 4 years (n = 368 dyads), proportions assessed secure were 59% and 71%, respectively. Proportions assessed avoidant were 15% and 11%; ambivalent 9% and 6%, and disorganised 17% and 12%, at 1 and 4 years. Continuity of attachment pattern was highest for the infant secure group. Of dyads initially classified disorganised in infancy, 36% remained so at the preschool assessment. Attachment and caregiving continuities across the infancy–preschool period were highest for the stable secure attachment group and lowest for the stable insecure attachment group. Loss of secure attachment to mother by age 4 years correlated with decreased maternal caregiving sensitivity, and acquisition of secure status by age 4 was associated with increased maternal sensitivity. We found no difference in caregiving sensitivity scores for mothers and fathers for female and male preschool children. Conclusions: The contemporary infant and preschool attachment proportions we report here closely mirror the patterns of those reported in prior decades, with an inclination towards secure base relationships. Our findings alert practitioners anew to the responsiveness of early attachment status to change in caregiving responsiveness and support ongoing investment in early identification of disorganised attachment.

Chronic insecurities that emerge from adverse experiences in early intimate partner relationships in adolescence and emerging adulthood can have profound impacts on mental health and well‐being. Less clear is the extent to which these experiences for parents impact subsequent relationships within and across generations. We examine the extent to which secure, dismissing, pre‐occupied, and fearful intimate partner relationships in adolescence and emerging adulthood, well before becoming a parent, are associated with next‐generation patterns of attachment between mothers and infant offspring. Data were drawn from a nested study of infant–mother attachment (n = 220) within the Australian Temperament Project Generation 3 Study (N = 1167, est. 1983). Intimate partner relationships in adolescence and young adulthood were assessed by self‐report at 23–24 years of age. Over a decade later, infant–mother attachment security was assessed at 12 months post‐partum. Young adult intimate partner relationships defined by high levels of fearful, pre‐occupied, and dismissing attachment styles were reported in 11%, 17%, and 38% of young mothers, respectively. Increases in fear of intimacy in relationships were associated with an increase in the odds, by around 50%, of infant–mother insecure attachments (vs secure; OR = 1.56, 95% CI = 1.07, 2.28) and disorganised attachments (vs organised; OR = 1.49, 95% CI = 1.00, 2.22). A mother's self‐reported history of fear of intimacy within young adult relationships predicts later insecure and disorganised mother–infant attachments. Guidance and greater support for young people navigating their earliest intimate relationships may not only prevent adverse relational experiences at the time but also on becoming a parent. Findings have relevance for family and infant mental health therapies. Translating these findings into supported conversations may help prevent infant–mother attachment difficulties, or later repair them, through validation of the lingering effects of early fear of intimacy and empowerment of parents to prevent next‐generation infant experiences of distrust.

This paper considers the role of academic training programs in the integration of family therapy and infant mental health (IMH) curricula. It takes the form of a conversation between senior academic staff of the Bouverie Centre in Australia and the special issue editors. Robyn Elliott and Colleen Cousins are family therapists, trauma specialists, and academics at the Bouverie Centre, La Trobe University. Robyn supervises the development and delivery of the Master of Clinical Family Therapy, accredited by the Australian Association of Family Therapy. Colleen is a psychologist and family therapist and coordinates the Graduate Certificate of Family Therapy program. They are in dialogue here with the special issue co‐editors, Jessica Opie and Jennifer McIntosh. We consider the degree to which current family therapy training holds the infant in mind, and approaches to deepening the future training nexus between IMH and family therapy. [ABSTRACT FROM AUTHOR]

The current study aimed to identity the optimal low-cost stroller cooling strategies for use in hot and moderately humid summer weather. A commercially available stroller was instrumented to assess the key parameters of the thermal environment. The cooling efficacy of eight different stroller configurations was examined in a counterbalanced order across 16 hot summer days (air temperature (Ta) = 33.3 ± 4.1 °C; relative humidity = 36.7 ± 15%; black globe temperature = 43.9 ± 4.6 °C). Compared with a standard-practice stroller configuration, combining a moist muslin draping with a battery-operated clip-on fan provided optimal in-stroller cooling, reducing the end-trial air temperature by 4.7 °C and the wet bulb globe temperature (WBGT) by 1.4 °C. In contrast, in-stroller temperatures were substantially increased by draping a dry muslin (Ta = +2.6 °C; WBGT = +0.9 °C) or flannelette (Ta = +3.7 °C; WBGT = +1.4 °C) cloth over the stroller carriage. These findings provide empirical evidence which may inform guidance aimed at protecting infants during hot weather. Practitioner summary: This study examined the efficacy of traditional and novel stroller cooling strategies for use in hot and moderately humid weather. Covering the carriage with a dry muslin cloth substantially increased stroller temperatures and should be avoided. Evaporative cooling methods reduced in-stroller temperatures. A moist muslin cloth draping combined with a fan provided optimal stroller cooling. [ABSTRACT FROM AUTHOR]

Aim: To summarise and critique existing knowledge and evidence relating to the utility, and post‐insertion complications surrounding tunnelled non‐cuffed central venous catheters (tncCVCs) in infants. Methods: A scoping review of original research studies reporting the use of, and post‐insertion complications associated with, tncCVCs in infants was completed. MeSH terms were used to formulate a systematic search, and data were extracted using a customised data extraction form. Data were analysed descriptively across key themes based on the research questions. Study quality was evaluated using the Mixed Methods Appraisal Tool. Results: The systematic search generated 3994 studies, of which 9 studies met final inclusion criteria. Studies included 644 tncCVCs in infants based in the USA, Europe and Australia. Most studies were retrospective cohort studies. The most common vein of insertion, where individually specified, was the internal jugular (n = 177). Tunnel length, where reported, was 2.5–5 cm. Infection rates were most commonly reported (eight studies), with results ranging from 0 to 12.8%, and device dislodgements of up to 20% reported. Participant follow‐up and definition of complications varied greatly between studies. Study quality across all papers was sound. Conclusions: This review has identified only a small number of studies, with small participant numbers, reporting the performance of tncCVCs in infants. Definitions of complications measured varied significantly between studies, and vastly different patient follow‐up protocols were reported. Further larger‐scale studies on the performance of tncCVC, employing internationally recognised reporting standards is warranted to ensure clinicians can make informed choices for medication and infusion delivery.

Coronavirus SARS‐CoV‐2 has fundamentally affected the health, healthcare delivery and daily life in all populations and age groups in Australia. The aim of this report is to summarise how it has affected the paediatric population with an emphasis on, but not limited to, the cardiac manifestations. A literature review and appraisal of data relating to SARS‐CoV‐2 cardiac manifestations and vaccination in the paediatric population was undertaken.The majority of children with SARS‐CoV‐2 infection recover well. However, a very small proportion may develop severe acute disease. In the sub‐acute phase, children may also develop a Kawasaki like illness, Paediatric Inflammatory Multisystem Syndrome temporally associated with SARS‐CoV‐2. Whilst not directly cardiac in nature, SARS‐CoV‐2 also affected children in other profound ways. Public health measures with widespread lockdowns appeared to disproportionately affect the paediatric population causing physical deconditioning and psychological harm. Vaccination against SARS‐CoV‐2 has proven to be safe and effective, but the small rate of complications did disproportionately affect teenage children with risks of myocarditis and pericarditis. The long term outcomes following myocarditis related to SARS‐Cov‐2 vaccination are yet to be clarified. When treating children in the era of SARS‐CoV‐2, Paediatricians need to be well aware of the risks of infection in the acute and sub‐acute phases, have a good understanding of the well‐established recommendations for vaccination, and also be cognisant of psychological impacts.

Background: Antenatal detection of fetal growth restriction allows the opportunity to increase surveillance and initiate intervention to prevent adverse outcomes. Detection of small for gestational age (SGA) fetuses with risk factor screening and selective ultrasonography is the standard of care in Australia, but evidence regarding performance is lacking. Aims: To evaluate the diagnostic performance of a risk factor‐based screening approach in detection of SGA neonates. Materials and methods: Retrospective cohort study conducted in a metropolitan maternity service, including all consecutive singleton deliveries over 20 weeks gestation from July 2016 to December 2017, and excluding terminations of pregnancy. An SGA neonate was defined by birthweight below the tenth percentile according to Australian reference ranges. Antenatally detected SGA cases were defined by estimated fetal weight or abdominal circumference below the tenth percentile for gestational age, or abnormal symphysio‐fundal height. The diagnostic accuracy of the screening protocol was calculated using detection rates and false‐positive rates. Results: There were 13 384 singleton pregnancies included. There were 1330 infants (10.0%) who were SGA at birth. Antenatal detection rate of SGA neonates was 39.6% (95% confidence interval (CI) 37.0–42.3%), with a false‐positive rate of 10.2% (95% CI 9.6–10.7%). There were 10 266 pregnancies (77.0%) which had at least one risk factor for an SGA infant. Of these, 6650 (64.8%) underwent at least one fetal growth ultrasound after 24 weeks gestation. Conclusions: Antenatal recognition of poor fetal growth is suboptimal using our current screening protocol. Three‐quarters of pregnancies demonstrated risk factors for delivering an SGA infant, but growth ultrasonography may be underutilised. [ABSTRACT FROM AUTHOR]

Current literature regarding the association of vitamin D insufficiency and food allergy is contradicting. The purpose of our study was to investigate this association. This is a systematic review and meta-analysis according to the PRISMA statement. PubMeD and Scopus databases were systematically searched for case–control studies investigating the association between pediatric food allergy and vitamin D insufficiency. Our search yielded 806 studies. Ten final studies were considered eligible for qualitative and quantitative analysis. Children with vitamin D insufficiency were found to have 68% more probability to present a food allergy episode (adjusted pooled OR: 1.68, 95% CI [1.25–2.27], p-value: 0.001). In their second year of life they were 4 times more likely to present a food allergy episode (adjusted pooled OR: 4.06, 95% CI [1.93–8.56], p-value: < 0.001), and 56% more probable to develop food sensitization (OR: 1.56, 95% CI [1.15–2.11], p-value: < 0.004). Children in Australia with vitamin D insufficiency were almost 4 times more likely to develop egg sensitization (adjusted OR: 3.79, 95% CI [1.19–12.08], p-value: 0.024). Children with vitamin D insufficiency were almost twice as likely to have peanut sensitization (OR: 1.96, 95% CI [1.08–3.57], p-value: 0.028). Conclusion: Decreased maternal vitamin D levels and infant vitamin D insufficiency appear to increase the incidence of food allergies, particularly in the second year of life. To confirm this association, multicenter longitudinal studies are required. What is Known: • In newborns and young children, vitamin D deficiency and insufficiency are prevalent. • The exact role of vitamin D in atopic diseases remains controversial. What is New: • Decreased maternal vitamin D levels and infant vitamin D insufficiency appear to increase the incidence of food allergies. This association is more evident in the second year of life.

Physiotherapy is an essential component in the management of cystic fibrosis (CF). To explore how parents of infants with CF experience physiotherapy clinic consultations. A qualitative study, informed by hermeneutic phenomenology, utilizing in-depth semi-structured interviews and daily diaries was conducted with 13 parents of infants (aged 0–2 yrs.) receiving physiotherapy care for CF in Australia. Three themes arose from the text. The first was that parents' physiotherapy clinic experience is influenced by the manner in which health professionals communicate to parents about physiotherapy in CF, as well as their own prior experience and knowledge. Secondly, parents receive conflicting messages from the physiotherapy consultation, but perceive the key message to be to prioritize adherence to physiotherapy. The final theme was that parents' expectations of the physiotherapy interaction were often not met, in particular a lack of practical physiotherapy education and training was reported. Parents of infants with CF seek an optimistic, practical and hands on approach during physiotherapy consultations. Exploring options for providing physiotherapy input outside of traditional clinic environments may help accommodate individual needs. Investigation into the manner in which physiotherapy education is communicated to parents is warranted in light of the influence on parents' expectations of physiotherapy. [ABSTRACT FROM AUTHOR]

Aim: To determine the prevalence of high flow nasal cannula (HFNC) therapy in infants presenting to hospital in Australia and New Zealand with bronchiolitis over four bronchiolitis seasons. Secondary aims were to determine temporal trends in HFNC use, and associations between HFNC, hospital length of stay (LOS) and intensive care unit (ICU) admission. Methods: A planned sub‐study of a multi‐centre international cluster randomised controlled trial investigating knowledge translation strategies for a bi‐national bronchiolitis guideline. Demographics, management and outcomes data were collected retrospectively for infants presenting with bronchiolitis to 26 hospitals between 1 May 2014 and 30 November 2017. Prevalence data are presented as absolute frequencies (95% confidence interval (CI)) with differences between groups for continuous and categorical variables analysed using linear and logistic regression, respectively. Results: 11 715 infants were included with 3392 (29.0%, 95% CI (28.1–29.8%)) receiving oxygen therapy; of whom 1817 (53.6%, 95% CI (51.9–55.3%)) received HFNC. Use of oxygen therapy did not change over the four bronchiolitis seasons (P = 0.12), while the proportion receiving HFNC increased (2014, 336/2587 (43.2%); 2017, 609/3720 (57.8%); P ≤ 0.001). Infants who received HFNC therapy were not substantially different to infants who received oxygen therapy without HFNC. HFNC use was associated with increases in both hospital LOS (P < 0.001) and ICU admissions (P < 0.001). Conclusion: Use of HFNC therapy for infants with bronchiolitis increased over 4 years. Of those who received oxygen therapy, the majority received HFNC therapy without improvement in hospital LOS or ICU admissions. Strategies to guide appropriate HFNC use in infants with bronchiolitis are required. [ABSTRACT FROM AUTHOR]

Background: Pregnant women are at increased risk for severe COVID‐19 and are a priority group for vaccination. The discrepancy in vaccination rates between pregnant and non‐pregnant cohorts is concerning. Aims: This study aimed to assess the perceptions and intentions of pregnant women toward COVID‐19 vaccination and explored vaccine uptake and reasons for vaccine hesitancy. Materials and method: A cross‐sectional exploratory design was performed evaluating pregnant women receiving care in two metropolitan maternity units in Western Australia. The main measurable outcomes included vaccination status, intention to be vaccinated, and reasons for delaying or declining vaccination. Results: In total, 218 women participated. Of these, 122 (56%) had not received either dose of the COVID‐19 vaccine. Sixty (28%) claimed that vaccination was not discussed with them and 33 (15%) reported being dissuaded from vaccination by a healthcare practitioner. Compared to vaccinated women, those who had not accepted vaccination were less likely to have had vaccination discussed by maternity staff, less aware that pregnant women are a priority group, and less aware that pregnancy increased the risk of severe illness. Unvaccinated women were concerned about the side effects of the vaccine for their newborn and their own health, felt there was inadequate information on safety during pregnancy, and felt that a lack of community transmission in Western Australia reduced the necessity to be vaccinated. Conclusion: Vaccine delay and hesitancy is common among pregnant women in Western Australia. Education of healthcare professionals and pregnant women on the recommendation for COVID‐19 vaccination in pregnancy is required. [ABSTRACT FROM AUTHOR]

Summary: Objective: Rapid weight gain (RWG) in infancy is strongly associated with subsequent obesity risk, but little is known about the factors driving RWG. This study explored the child and maternal factors associated with infant RWG. Methods: Data from seven Australian and New Zealand cohorts were used (n = 4542). Infant RWG was defined as a change in weight z‐score ≥0.67 from birth to age 1 year. Univariable and multivariable logistic regression assessed the association between child and maternal factors and infant RWG in each cohort. Meta‐analysis was conducted to obtain pooled effect sizes. Results: Multivariable analyses revealed boys were more likely to experience RWG (OR 1.42 95% CI 1.22, 1.66) than girls. Higher birth weight in kg (OR 0.09, 95% CI 0.04, 0.20) and gestational age in weeks (OR 0.69, 95% CI 0.48, 0.98) were associated with lower RWG risk. Children who were breastfed for ≥6 months showed lower RWG risk (OR 0.45, 95% CI 0.38, 0.53). Children of native‐born versus overseas‐born women appeared to have higher RWG risk (OR 1.37, 95% CI 0.99, 1.90). Maternal smoking during pregnancy increased RWG risk (OR 1.60, 95% CI 1.28, 2.01), whereas children who started solids ≥6 months (OR 0.77, 95% CI 0.63, 0.93) and children with siblings (OR 0.68, 95% CI 0.57, 0.81) showed lower RWG risk in univariable analysis, but these associations were attenuated in multivariable analysis. No association was found for maternal age, education, marital status and pre‐pregnancy BMI. Conclusion: Maternal country of birth, smoking status, child sex, birth weight, gestational age, infant feeding and parity were potential determinants of infant RWG. [ABSTRACT FROM AUTHOR]

Objective: To examine recent changes in the birth prevalence of cerebral palsy in Australia; to examine the functional mobility of children with cerebral palsy by residential remoteness., Study Design: Population-based register study; analysis of Australian Cerebral Palsy Register (ACPR) data., Setting, Participants: Children with cerebral palsy born in Australia, 1995-2016, and included in the ACPR at the time of the most recent state/territory data provision (31 July 2022)., Main Outcome Measures: Change in birth prevalence of cerebral palsy, of cerebral palsy acquired pre- or perinatally (in utero to day 28 after birth), both overall and by gestational age group (less than 28, 28-31, 32-36, 37 or more weeks), and of cerebral palsy acquired post-neonatally (day 29 to two years of age); gross motor function classification by residential remoteness., Results: Data for 10 855 children with cerebral palsy born during 1995-2016 were available, 6258 of whom were boys (57.7%). The birth prevalence of cerebral palsy in the three states with complete case ascertainment (South Australia, Victoria, Western Australia) declined from 2.1 (95% confidence interval [CI], 1.9-2.4) cases per 1000 live births in 1995-1996 to 1.5 (95% CI, 1.3-1.7) cases per 1000 live births in 2015-2016. The birth prevalence of pre- or perinatally acquired cerebral palsy declined from 2.0 (95% CI, 1.7-2.3) to 1.4 (95% CI, 1.2-1.6) cases per 1000 live births; statistically significant declines were noted for all gestational ages except 32-36 weeks. The decline in birth prevalence of post-neonatally acquired cerebral palsy, from 0.15 (95% CI, 0.11-0.21) to 0.08 (95% CI, 0.05-0.12) cases per 1000 live births, was not statistically significant. Overall, 3.4% of children with cerebral palsy (307 children) lived in remote or very remote areas, a larger proportion than for all Australians (2.0%); the proportion of children in these areas who required wheelchairs for mobility was larger (31.3%) than that of children with cerebral palsy in major cities or regional areas (each 26.1%)., Conclusions: The birth prevalence of cerebral palsy declined markedly in Australia during 1995-2016, reflecting the effects of advances in maternal and perinatal care. Our findings highlight the need to provide equitable, culturally safe access to antenatal services for women, and to health and disability services for people with cerebral palsy, across Australia., (© 2024 AMPCo Pty Ltd.)

Human respiratory syncytial virus (RSV) is a major cause of acute respiratory infection. In 2020, RSV was eliminated from New Zealand due to non-pharmaceutical interventions (NPI) used to control the spread of SARS-CoV-2. However, in 2021, following a brief quarantine-free travel agreement with Australia, there was a large-scale nationwide outbreak of RSV that led to reported cases more than five-times higher than typical seasonal patterns. We generated 1470 viral genomes of both RSV-A and RSV-B sampled between 2015-2022 from across New Zealand. Using a phylodynamics approach, we used these data to better understand RSV transmission patterns in New Zealand prior to 2020, and how RSV became re-established in the community following the relaxation of COVID-19 restrictions. We found that in 2021, there was a large epidemic of RSV due to an increase in importations, leading to several large genomic clusters of both RSV-A ON1 and RSV-B BA9 genotypes. However, while a number of viral importations were detected, there was also a major reduction in RSV genetic diversity compared to pre-pandemic years. These data reveal the impact of NPI used during the COVID-19 pandemic on other respiratory infections and highlight the important insights that can be gained from viral genomes., Competing Interests: Competing interests The authors declare no competing interests., (© 2024.

Background: Foreign bodies (FBs) in the ears and nose are common presentations among paediatric patients, necessitating prompt and appropriate management to avoid potential complications., Objective: This article presents a standardised approach for FB retrieval based on local clinical data from a tertiary paediatric centre, addressing the challenges of identifying patients requiring specialist referral., Discussion: The approach involves a detailed initial consultation and succinct examination to determine the most suitable retrieval method. Patient preparation and equipment availability are key to successful outcomes. A combination of microsuction and alligator forceps with adequate illumination is strongly recommended, along with various adjunct tools commonly available. Urgent referral to otorhinolaryngology is indicated for button batteries and previous failed attempts. This comprehensive approach seeks to achieve successful FB removal and optimise patient outcomes in both community and hospital settings.

The bacterium Vibrio parahaemolyticus is ubiquitous in tropical and temperate waters throughout the world and causes infections in humans resulting from water exposure and from ingestion of contaminated raw or undercooked seafood, such as oysters. We describe a nationwide outbreak of enteric infections caused by Vibrio parahaemolyticus in Australia during September 2021-January 2022. A total of 268 persons were linked with the outbreak, 97% of whom reported consuming Australia-grown oysters. Cases were reported from all states and territories of Australia. The outbreak comprised 2 distinct strains of V. parahaemolyticus, sequence types 417 and 50. We traced oysters with V. parahaemolyticus proliferation back to a common growing region within the state of South Australia. The outbreak prompted a national recall of oysters and subsequent improvements in postharvest processing of the shellfish.

Inpatient parent-infant psychiatric units (PIUs) are considered "gold standard" for treating maternal mental illness, with well-documented positive outcomes for mothers. However, little research addresses outcomes for infants in these units, who often face significant developmental and socio-emotional adversity. This pilot study aimed to evaluate the characteristics and progress of an Australian PIU population, focusing on the impact of PIU admission on infant outcomes. Over 3 months, 31 consecutively admitted mother-infant pairs (dyads) were assessed through interviews, observations, and standardized measures to evaluate maternal and infant characteristics and progress from admission to discharge. Maternal well-being and the mother-infant relationship improved. Infants exhibited high levels of physical (29%) and developmental concerns (80.6%). 22.6% receiving an Axis I infant mental health diagnosis. Infant socio-emotional responsiveness improved significantly, as measured by the modified Alarm-Distress Baby Scale, indicating a positive impact of PIU admission. The small sample size and reliance on clinician-observed measures limit the generalizability of the findings. PIU infants are particularly vulnerable, and PIU admission may ameliorate socio-emotional responsiveness. Further research with larger samples and extended follow-up is needed to determine the most effective intervention strategies during and after PIU admission to maximize benefits for these infants., (© 2024 Michigan Association for Infant Mental Health.)

Background: Accurate assessment of body composition during infancy is an important marker of early growth. This study aimed to develop anthropometric models to predict body composition in 3-24-month-old infants from diverse socioeconomic settings and ethnic groups., Methods: An observational, longitudinal, prospective, multi-country study of infants from 3 to 24 months with body composition assessed at three monthly intervals using deuterium dilution (DD) and anthropometry. Linear mixed modelling was utilized to generate sex-specific fat mass (FM) and fat-free mass (FFM) prediction equations, using length(m), weight-for-length (kg/m), triceps and subscapular skinfolds and South Asian ethnicity as variables. The study sample consisted of 1896 (942 measurements from 310 girls) training data sets, 941 (441 measurements from 154 girls) validation data sets of 3-24 months from Brazil, Pakistan, South Africa and Sri Lanka. The external validation group (test) comprised 349 measurements from 250 (185 from 124 girls) infants 3-6 months of age from South Africa, Australia and India., Results: Sex-specific equations for three age categories (3-9 months; 10-18 months; 19-24 months) were developed, validated on same population and externally validated. Root mean squared error (RMSE) was similar between training, validation and test data for assessment of FM and FFM in boys and in girls. RMSPE and mean absolute percentage error (MAPE) were higher in validation compared to test data for predicting FM, however, in the assessment of FFM, both measures were lower in validation data. RMSE for test data from South Africa (M/F-0.46/0.45 kg) showed good agreement with validation data for assessment of FFM compared to Australia (M/F-0.51/0.33 kg) and India(M/F-0.77/0.80 kg)., Conclusions: Anthropometry-based FFM prediction equations provide acceptable results. Assessments based on equations developed on similar populations are more applicable than those developed from a different population., (© 2024. The Author(s).)

Parents' language use is an important context for early socialization. We examined the relationship between parents' self-reported mindfulness and observed language use in two forms of attachment-relevant communication. Sixty-three parents of 6-18-month-old infants from Australia (n = 32) and New Zealand (n = 31) completed the five facets of mindfulness-short form (FFMQ-SF) questionnaire, the adult attachment interview (AAI), and a 10-min play session with their infant. We examined parents' frequency of word usage within the categories of the linguistic inquiry word count (LIWC) text analysis program to explore the relationship between mindfulness and language use. Mindfulness was associated with cognitive, affective, perceptual, and time orientation language use in the AAI. However, fewer associations were identified between mindfulness and language use in the parent-infant play session. Results are discussed in terms of their relevance to mindfulness and attachment., (© 2024 The Author(s).

Background: Given the importance of infancy for establishing growth trajectories, with later-life health consequences, we investigated longitudinal body composition among infants from six economically and ethnically diverse countries., Methods: We recruited mother-infant dyads using the WHO Multicenter Growth Reference Study criteria. We measured fat-free mass (FFM) in 1393 (49% female) infants from birth to 6 months of age (Australia, India, and South Africa; n = 468), 3-24 months of age (Brazil, Pakistan, South Africa, and Sri Lanka; n = 925), and derived fat mass (FM), fat mass index (FMI), and fat-free mass index (FFMI). Height-for-age (HAZ), weight-for-age (WAZ), and weight-for-length (WHZ) Z-scores were computed. Sex differences were assessed using a t-test, and country differences using a one-way analysis of covariance. We further compared subsamples of children with average (-0.25 > HAZ < +0.25), below-average (≤-0.25) and above-average (≥+0.25) HAZ., Results: HAZ performed well between 0 and 6 months, but less so between 3 and 24 months. The stunting prevalence peaked at 10.3% for boys and 7.8% for girls, at 24 months. By 24 months, girls had greater FMI (10%) than boys. There were significant differences in FFM (both sexes in all countries) and FM (Brazilian boys, Pakistani and South African girls) by 24 months of age between infants with average, above-average, and below-average HAZ., Conclusion: In a multi-country sample representing more ideal maternal conditions, body composition was heterogeneous even among infants who exhibited ideal length. Having a mean HAZ close to the median of the WHO standard for length reduced FFM between-country heterogeneity but not FM, suggesting that other factors may influence adiposity., (© 2024.

Background: Despite known inequalities, little is understood about the burden and healthcare experiences of Aboriginal and Torres Strait Islander children who sustain a burn injury and their families., Methods: The Coolamon Study recruited parents and carers whose children (aged <16 years) were Aboriginal and / or Torres Strait Islander children and had presented to burn units across four Australian states, New South Wales (Sydney), Northern Territory (Darwin), Queensland (Brisbane, Townsville) and South Australia (Adelaide), between 2015 and 2018. Consent was obtained and carers completed baseline and subsequent interviews at 3, 6, 12 and 24 months. Data were collected on the injury event, patient care and safety, sociodemographic factors, health related quality of life (PedsQual), and psychological distress (Kessler K-5)., Results: Of the 208 participants, 64 % were male; 26 % were aged less than 2 years and 37 % aged 2-4 years. The most common burn mechanisms were scalds (37 %), contact (33 %) and flame burns (21 %), with more severe burns and flame burns occurring in rural and remote settings. Most carers rated their child's care as either excellent or very good (82 %). Family distress, measured by the K-5, lessened over the 24 months, however the changes were not statistically significant. While 77 % of carers reported that they received enough information, 18 % reported they would have liked more, and 3 % reported no information was provided before treatment. Parents described mixed access to information about the types of support available to them, such as accommodation, meals, travel or cultural support., Conclusion: Data from this cohort provide rich new information about risk factors and care received from point of injury through to rehabilitation for Aboriginal and Torres Strait Islander children with burns, providing unique insights into what is needed for appropriate, culturally safe care., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Engaging in clinical research includes confronting challenges about the uncertainty around outcomes and ramifications the results may have on practice. This is pertinent for osteopathy where little is known about the experiences of osteopaths involved in clinical trials. The aim of this study was to explore the lived experience of osteopaths who participated in a randomised controlled trial for infantile colic. The study was informed by a principles-based approach to clinical ethics and their application to practice., Design: Qualitative study using semi-structured interviews and reflexive thematic analysis., Setting: An international two-arm pragmatic randomised controlled trial (the CUTIES trial) to evaluate the effectiveness of osteopathic care for infantile colic., Methods: A principles-based approach to clinical ethics and their application to practice for osteopaths asked to make decisions about participating in a clinical trial was used. Osteopaths from the UK and Australia who completed the CUTIES trial training were invited to be interviewed about their experiences, regardless of whether they went on to recruit infants in the trial. Interviewees were asked about their reasons for wanting to participate in the CUTIES trial, why they decided to continue or not to continue in the trial and, for those who completed the trial, their personal experiences as participants in the trial. Data were analysed using reflexive thematic analysis., Results: Nine osteopaths were interviewed. Three themes were identified from the data: Paradigm dilemma - observed clinical outcomes vs scientific evidence for mechanism of effects; trial-related ethical dilemmas; and trial outcome dilemmas., Conclusion: Participating in the CUTIES trial required osteopaths to overcome clinical ethical dilemmas for the benefit of patients, the research, and the profession., (Copyright © 2024 The Authors.

Aim: One third of Australian children diagnosed with type 1 diabetes present with life-threatening diabetic ketoacidosis (DKA) at diagnosis. Screening for early-stage, presymptomatic type 1 diabetes, with ongoing follow-up, can substantially reduce this risk (<5% risk). Several screening models are being trialled internationally, without consensus on the optimal approach. This pilot study aims to assess three models for a routine, population-wide screening programme in Australia., Methods: An implementation science-guided pilot study to evaluate the feasibility, acceptability and costs of three screening models in children will be conducted between July 2022 and June 2024. These models are as follows: (1) Genetic risk-stratified screening using newborn heel prick dried bloodspots, followed by autoantibody testing from 11 months of age; (2) genetic risk-stratified screening of infant (6-12 months) saliva followed by autoantibody testing from 10 months of age; and (3) autoantibody screening using capillary dried bloodspots collected from children aged 2, 6 or 10 years. Cohorts for each model will be recruited from targeted geographic areas across Australia involving ≥2 states per cohort, with a recruitment target of up to 3000 children per cohort (total up to 9000 children). The primary outcome is screening uptake for each cohort. Secondary outcomes include programme feasibility, costs, parental anxiety, risk perception, satisfaction, well-being and quality of life, and health professional attitudes and satisfaction., Conclusions: This pilot is the first direct comparison of three screening implementation models for general population screening. Findings will provide evidence to inform a potential national screening programme for Australian children., Trial Registration: ACTRN12622000381785., (© 2024 The Author(s).

Background: The development of new morbidities has become increasingly identified in paediatric critical care medicine. To date, there has been limited research of long-term outcomes following paediatric critical illness in Australia., Objectives: The objective of this study was to quantify neurodevelopmental impairments in children following paediatric intensive care unit (PICU) discharge and their association with health-related quality of life (HRQoL)., Methods: A single-centre ambidirectional cohort study at an Australian hospital. Parents of children admitted to the PICU between 2015 and 2017 were invited to participate. Neurodevelopmental outcome and HRQoL was prospectively evaluated, using the Ages and Stages Questionnaire (<5 years), Strengths and Difficulties Questionnaire (≥5 years), and Pediatric Quality of Life Inventory™, respectively., Results: A total of 230 parents of critically ill children participated. Children were 1.9 years old (median, interquartile range [IQR]: 0.2, 7.5), male (59.6%), and ventilated (49.1%) at PICU admission. The median time to follow-up was 24.4 months (IQR: 16.3, 36.7). Parent respondents were more likely to be female (85.5%), White (88.3%), and partnered (81.1%). The incidence of overall neurodevelopmental impairment was 30% (33% in children aged <5 years; 24% in children aged ≥5 years). The incidence of poor HRQoL was 37.9%. History of developmental delay was independently associated with overall neurodevelopmental impairment (adjusted odds ratio [aOR]: 4.21, 95% confidence interval: 2.05, 8.63) and poor HRQoL (aOR: 7.29, 95% confidence interval: 3.26, 16.27). Two or more PICU admissions (aOR: 4.10, IQR: 1.82, 9.26) was also associated with poor HRQoL., Conclusions: This is the first contemporary view of PICU long-term outcomes conducted in Australia and significantly informs ongoing research in this area. Approximately one-third of PICU survivors demonstrate neurodevelopmental impairment and reduced quality of life. Multiple domains of post-intensive care syndrome-paediatrics must be considered to have a comprehensive understanding of child outcomes. Assessment of baseline/premorbid functioning is also essential in order to understand the true impact of illness and PICU admission., (Copyright © 2024 Australian College of Critical Care Nurses Ltd.

Background: Infant feeding guidelines in Australia changed in 2016 to recommend introducing common allergy-causing foods by age 1 year to prevent food allergy. Although most Australian infants now eat peanut and egg by age 6 months, some still develop food allergy despite the early introduction of allergens., Objectives: To describe the prevalence of food allergy in a cohort recruited after introducing the nationwide allergy prevention recommendations; identify characteristics of infants who developed allergy despite early introduction of allergens; and estimate the causal effect of modifiable exposures on food allergy prevalence and whether this differed between infants who were introduced to allergens before or after age 6 months., Methods: We recruited a population-based sample of 12-month-old infants in Melbourne, Australia. Infants had skin prick tests to four foods and parents completed questionnaires. Infants with evidence of sensitization were offered oral food challenges. Prevalence estimates were adjusted using inverse probability weighting., Results: In a cohort of infants (n = 1,420) in which nearly all infants had been introduced to common allergens such as egg, milk, and peanut by age 1 year, the prevalence of food allergy remained high at 11.3% (95% CI, 9.6-13.4). Infants who developed food allergy despite introduction of the allergen by age 6 months were more likely to have Asian-born parents. Early-onset moderate or severe eczema was associated with an increased odds of food allergy irrespective of whether allergens were introduced before or after age 6 months. Among infants who were introduced to peanut at age 6 months or earlier, antibiotic use by age 6 months was associated with an increased odds of peanut allergy (adjusted odds ratio = 6.03; 95% CI, 1.15-31.60)., Conclusions: In a cohort in which early allergen introduction was common, the prevalence of food allergy remained high. Infants who developed food allergy despite introduction of the respective allergen by age 6 months were more likely to have had Asian parents and early-onset eczema. New interventions are needed for infants with a phenotype of food allergy that is not amenable to early allergen introduction., (Copyright © 2024 American Academy of Allergy, Asthma & Immunology.

Background/objectives: Two compartment (2 C) models of body composition, including Air Displacement Plethysmography (ADP) and Deuterium Dilution (DD), assume constant composition of fat-free mass (FFM), while 3-compartment (3 C) model overcomes some of these assumptions; studies are limited in infants. The objective of the present study is to compare 3 C estimates of body composition in 6-mo. old infants from Australia, India, and South Africa, including FFM density and hydration, compare with published literature and to evaluate agreement of body composition estimates from ADP and DD., Methods: Body volume and water were measured in 176 healthy infants using ADP and DD. 3C-model estimates of fat mass (FM), FFM and its composition were calculated, compared between countries (age and sex adjusted) and with published literature. Agreement between estimates from ADP and DD were compared by Bland-Altman and correlation analyses., Results: South African infants had significantly higher % FM (11.5%) and density of FFM compared to Australian infants. Australian infants had significantly higher % FFM (74.7 ± 4.4%) compared to South African infants (71.4 ± 5.0) and higher FFMI (12.7 ± 0.8 kg/m 2 ) compared to South African (12.3 ± 1.2 kg/m 2 ) and Indian infants (11.9 ± 1.0 kg/m 2 ). FFM composition of present study differed significantly from literature. Pooled three country estimates of FM and FFM were comparable between ADP and DD; mean difference of -0.05 (95% CI: -0.64, +0.55) kg and +0.05 (95% CI: -0.55, +0.64) kg., Conclusions: 3C-model estimates of body composition in infants differed between countries; future studies are needed to confirm these findings and investigate causes for the differences., (© 2023.

Background: Vital signs assessment is critical for patient surveillance and safety. Research has found, however, that this assessment is often neglected in clinical practice. The reasons for this are unclear as few studies have explored this issue. Those studies that have are small, single site studies and found that culture and poor understanding are contributing factors., Aim: The aim was to explore the link between the clinical neglect of vital signs assessment and patient mortality and provide a better understanding of factors influencing vital signs assessment in the context of acute patient care. Coroners' reports represent an untapped source of information regarding shortfalls in vital signs assessment. Using a framework analysis, an audit was conducted of the Australian National Coronial Information System for cases where vital signs' assessment was mentioned in coronial reports., Results: Fifty-eight cases met the eligibility criteria, with deceased patients aged from 7 days to 93 years. Key themes related to absence of reassessment of vital signs, inappropriate delegation, passing responsibility to another staff member and not following policy., Conclusions: The findings reflect a combination of individual and institutional failings and suggest that vital signs assessment was not considered a priority aspect of care., Relevance to Clinical Practice: Vital signs assessment must be considered an essential aspect of clinical care in all patients. This important aspect of care should be emphasized across all domains of patient care., (© 2024 The Authors.

Background/objective: Available evidence on infant body composition is limited. This study aimed to investigate factors associated with body composition at 6 and 24 months., Subjects/methods: Multicenter study with data from a 0 to 6-mo cohort (Australia, India and South Africa) and a 3 to 24-mo cohort (Brazil, Pakistan, South Africa, and Sri Lanka). For the 0-6-mo cohort, body composition was assessed by air-displacement plethysmography (ADP) and for the 3-24-month cohort by the deuterium dilution (DD) technique. Fat mass (FM), fat-free mass (FFM), FM index (FMI), and FFM index (FFMI) were calculated. Independent variables comprised the Gini index of the country, maternal and infant characteristics, and breastfeeding pattern at 3 months. For the 3-24-mo cohort, breastfeeding, and minimum dietary diversity (MDD) at 12 months were also included. Crude and adjusted analyses stratified by sex were conducted by multilevel modelling using mixed models., Results: At 6 months, every 1 kg increase in birth weight was associated with an increase of 0.716 kg in FFM and 0.582 kg/m 2 in FFMI in girls, whereas in boys, the increase was of 0.277 kg in FFM. At 24 months, compared to those weaned before 12 months, girls still breastfed at 12 months presented a decrease of 0.225 kg in FM, 0.645 kg in FFM and 0.459 kg/m 2 in FFMI, and in boys the decreases were of 0.467 kg in FM, 0.603 kg in FFM and 0.628 kg/m 2 in FFMI., Conclusion: Birth weight and breastfeeding are independent predictors of body composition in early life, irrespective of sex., (© 2023.

Background: Catch-up vaccination is a personalised process through which children with missing recommended vaccinations or incomplete vaccination records are brought up to date with the Australian vaccination schedule. Navigating childhood catch-up vaccination can be difficult for migrant parents with inadequate health system knowledge and competing priorities during settlement. This study aimed to understand the experiences of migrant parents with childhood catch-up vaccination and co-design an intervention to improve the process., Methods: We recruited migrant parents who had attended the City of Melbourne Immunisation Service in Melbourne, Australia to participate in a qualitative co-design study between June and August 2022. Expression of interest emails were sent by the service, and we recruited eligible participants. In Phase One, we conducted group interviews with parents to understand their experiences and preferences for an intervention, these were analysed using inductive and framework analysis. In Phase Two, we designed prototype interventions based on parents' preferences and suggestions. In Phase Three, parents shared their feedback on each prototype., Results: Fourteen migrant parents participated in the study. Most parents did not discover the need for catch-up vaccination until childcare or kindergarten enrolment. The lack of information received about vaccination requirements and difficulty navigating the health system made the process challenging and time-consuming. Based on these Phase One themes, we designed a printout, mobile application, and website prototype. All three were well-received in Phase Three. Overall, parents' top three considerations for any intervention were 1) digital and online accessibility, 2) inclusion of step-by-step processes outlining catch-up vaccination; and 3) inclusion of a checklist., Conclusions: Migrant parents lack information about childhood catch-up vaccination in Australia. A relatively simple intervention could help parents more easily navigate the process, thereby saving time and stress. The next steps are to seek funding to pilot such an intervention to assess practicality and usefulness., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: JT is an investigator on a project grant sponsored by Industry.

Objectives and importance of study: Australian children frequently travel overseas, but little is known about their travel-related morbidity. We aimed to describe the spectrum of illness and injury in returned travellers presenting to the largest paediatric referral centre in NSW, the Children's Hospital at Westmead (CHW)., Study Type: Observational cohort study., Methods: In the 18 months immediately before the COVID-19 pandemic (2018-2020), we prospectively collected demographic, travel and clinical data from children with travel-acquired illness or injury identified by active surveillance of CHW Emergency Department attendees and referrals to the infectious diseases service., Results: We identified 587 returned child travellers with an illness or injury associated with overseas travel. Most were aged younger than 5 (62.8%) and had travelled within the Asia-Pacific region (84.6%). The main reason for travel, where recorded (50.3%), was visiting friends and relatives (VFR)(65.4%). Most travellers (90.1%) had a common childhood infection, illness or injury coincidentally acquired during travel, including respiratory infection (37.5%), acute diarrhoea (15.7%) and nonspecific febrile illness (13.1%). Exotic/nonendemic infections were uncommon (9.9%, including potential rabies exposure) but were associated with much higher admission rates than 'cosmopolitan' (globally distributed) diseases (74.2% vs 21.9%). Most of these occurred in VFR travellers (86.3%); enteric fever, largely acquired in South Asia, predominated (51.7%). One in five admitted patients had a disease for which specific pretravel vaccination is available. Receipt of pretravel vaccines was infrequently recorded., Conclusions: Returned child travellers in Western Sydney frequently presented with respiratory infections and may be a key population for surveillance of imported respiratory viruses. The burden of exotic disease was small and borne by VFR travellers. Travel-related illness in Western Sydney could be reduced by health education of travellers and targeted pretravel vaccination, especially typhoid vaccination for VFR travellers to South Asia. Universal, systematic screening of emergency department attendees for recent overseas travel would improve surveillance of travel-related illness., Competing Interests: None declared

Objectives and importance of the study: Pharmacist-administered vaccination has expanded in Australia but has not been comprehensively assessed. We aimed to assess the pharmacists' role in vaccination in Australia before and during the first year of the COVID-19 pandemic, as well as the completeness of data on pharmacist-administered immunisations., Study Type: Cross-sectional study., Methods: We analysed data on pharmacist-administered vaccinations that were reported to the Australian Immunisation Register (AIR) between 2016 and 2019, categorised by gender, jurisdiction, age group and vaccine type. We conducted a national survey of community pharmacists providing vaccination services during June and July 2020 to understand how pharmacists record and report vaccinations to the AIR. We assessed data completeness by comparing the number of vaccinations reported by surveyed pharmacists to the number recorded on the AIR., Results: 576 780 pharmacist-administered vaccinations were recorded on the AIR between 2016 and 2019, of which 94.7% were influenza vaccines. The proportion of vaccinations given by pharmacists increased each year, from <0.001% in 2016 to 2.7% in 2019. Between 2017 and 2019, rates of pharmacist-administered vaccinations were highest among people aged 60-64 years (2046 per 100 000 people) and those living in regional areas (1074 per 100 000 people). Among 243 survey respondents, 57.8% (126/223) reported vaccinations to the AIR automatically via software, 27.8% (62/223) manually entered data and 13.5% (30/223) used both methods. Of the 87 665 vaccination encounters recorded by 121 respondents, 82.2% (72 045/87 665) were recorded on the AIR. There were more AIR-recorded encounters from those who reported automatically via software (84.8% [49 309/58 134]) than from those who manually entered data (68.3% [12 127/17 746])., Conclusions: Pharmacists have an increasing role in providing vaccination services in Australia, with great potential to improve coverage among adults and populations in regional locations. Measures introduced during the COVID-19 pandemic may have increased the uptake of electronic methods of recording and reporting data, which can improve data completeness. Our results provide an assessment of the first 5 years of pharmacist vaccination services in Australia, against which future evaluations of the impacts of policy changes during the COVID-19 pandemic can be compared., Competing Interests: None declared

Asthma is one of the most common chronic illnesses affecting children. Long-term asthma control medications (LTACMs) are an important aspect of asthma management, with under-prescription associated with poor asthma control and increased asthma deaths. This study aimed to document temporal trends in the prescribing of LTACMs for paediatric patients for asthma-related presentations to Australian general practice registrars (trainees). Longitudinal analyses of data from 2010 to 2022 from the Registrars Clinical Encounters in Training study were undertaken. Proportions of paediatric presentations where LTACMs were prescribed were calculated, and temporal trends analysed and graphed. There was no change over time in registrar prescribing of LTACMs for paediatric asthma, although temporal changes were seen in the types of LTACMs prescribed. The lack of temporal increase in overall LTACMs prescription, despite evidence showing their importance in preventing asthma morbidity and mortality, has significant educational, clinical, and policy implications., (© 2024.

Objective: Global public health agencies have recommended stronger regulation of food marketing to protect children's diets. This study assessed commercial foods for infants and toddlers available in Australian supermarkets for compliance with the World Health Organization (WHO) Regional Office for Europe's Nutrient and Promotion Profile Model: supporting appropriate promotion of food products for infants and young children 6-36 months in the WHO European Region (NPPM)., Design: Dietitians assessed a sample of commercial foods for infants and toddlers against the composition, labelling and promotion requirements of the NPPM., Setting: Australia., Participants: Commercial foods for infants and toddlers ( n 45) available in two major Australian supermarkets, purposely sampled across product categories and brands., Results: Fewer than one quarter (23 %) of the assessed products met all nutrient content requirements of the NPPM. No products met all of the labelling or promotional requirements. All products included at least one promotional marketing claim that was not permitted under the NPPM., Conclusions: The NPPM is useful to assess and monitor the nutritional composition and prevalence of marketing claims on commercial foods for infants and toddlers. Findings of noncompliance with the NPPM recommendations indicate an urgent need for stronger government regulation of the composition, labelling and marketing of commercial foods for infants and toddlers in Australia.

Background: A number of respiratory syncytial virus (RSV) prevention products have recently been approved in Australia. These products focus on highest risk groups, aiming to prevent RSV disease in young infants and older adults. While not currently included in the National Immunisation Program (NIP), an RSV vaccine (Arexvy, GlaxoSmithKline [GSK]) is available privately for adults ≥60 years, and some Australian jurisdictions have commenced RSV monoclonal antibody (nirsevimab) programs for infants in 2024., Objective: This article summarises safety data regarding RSV prevention products approved in Australia, including vaccines for adults ≥60 years, maternal vaccines and monoclonal antibodies for infants., Discussion: Clinical trial data found these products were largely well tolerated, with most local and systemic reactions being mild-moderate and short-lived. Proportions of serious adverse events were low. While very rare, potential safety signals being further assessed include risk of preterm birth following the maternal vaccine (Abrysvo, Pfizer) and Guillain-Barré syndrome (GBS) following RSV vaccines in older adults (Abrysvo and Arexvy). Close monitoring of these adverse events of special interest via post-licensure surveillance is underway.

Background: Studies have shown that abnormal temperature at night is a risk factor for respiratory health. However, there is limited evidence on the impact of hot and cold nights on cause-specific diseases such as pneumonia, which is a leading cause of morbidity and mortality in children., Methods: We collected daily data on pneumonia hospitalisations in children under five years from 2011 to 2017 in three low-, middle- and high-income countries (Bangladesh, China, and Australia). The intensity of hot and cold nights was measured by excess temperature. A space-time-stratified case-crossover analysis was used to estimate the association between hot and cold nights and childhood pneumonia hospitalisations. We further estimated the fraction of childhood pneumonia hospitalisations attributable to hot and cold nights., Results: Both hot and cold nights were associated with an increased risk of hospitalisations for childhood pneumonia in low-, middle-, and high-income countries, with a greater disease burden from hot nights. Specifically, the fraction of childhood pneumonia attributable to hot nights was the largest in Australia [21.2%, 95% confidence interval (CI): 11.8%-28.1%], followed by Bangladesh (15.2%, 95% CI: 4.1%-23.8%) and China (2.7%, 95% CI: 0.4%-4.7%). Additionally, the fraction of childhood pneumonia attributable to cold nights was 1.3% (95% CI: 0.4%-2.0%) in Bangladesh and 0.4% (95% CI: 0.1%-0.7%) in China., Conclusion: This multi-country study suggests that hot and cold nights are not only associated with a higher risk of pneumonia hospitalisations in children but also responsible for substantial fraction of hospitalisations, with a greater impact from hot nights., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Introduction: Donor leucocyte survival following red blood cell (RBC) transfusion, known as transfusion-associated microchimerism (TAM), can occur in some patients. In Australia, despite the introduction of leucocyte filtration (leucodepletion) during RBC manufacture, TAM has been detected in adult trauma patients. However, the incidence of TAM in Australian pediatric patients has not been analyzed., Methods: Patients aged 0-16 years were recruited across two cohorts. Retrospective participants had RBC transfusion between January 1, 2002 and November 15, 2017 and prospective participants received RBC transfusion between December 1, 2016 and November 25, 2020. Twelve bi-allelic insertion/deletion (InDel) polymorphisms were used to detect microchimerism amplification patterns using real-time PCR (RT-PCR) and droplet digital PCR (ddPCR)., Results: Of the retrospective cohort (n = 40), six patients showed amplification of InDel sequences indicating potential microchimerism. For three patients, minor InDel sequences were detected using RT-PCR only, two patients had minor InDel amplification using ddPCR only, and one patient had minor InDel amplification that was confirmed using both techniques. Amplification of minor sequences occurred in three patients who had received a bone marrow transplant in addition to RBC transfusion. In the prospective cohort (n = 25), no InDel amplification indicating potential microchimerism was detected using RT-PCR., Discussion: Cell-based therapies had been administered in three patients where microchimerism amplification patterns were detected. Three patients have microchimerism that may be attributed to RBC transfusion. In prospective patients, who received leucodepleted and gamma-irradiated RBC units, no potential microchimerism amplification were detected. ddPCR may be a suitable technique for TAM analysis but requires further evaluation., (© 2024 The Author(s).

Tuberous sclerosis complex (TSC) is a variable multisystem disorder. The "no mutations identified" (NMI) group are reportedly phenotypically milder than those with an identified molecular cause, and often have mosaic or intronic variants not detected by standard sequencing methods., Methods: We describe the phenotypes in an Australian TSC NMI group (n = 18) and a molecular testing strategy implementable in a diagnostic laboratory. Massively parallel sequencing (MPS) of the whole genomic regions of TSC1 and TSC2 was performed using DNA extracted from multiple tissue samples per participant., Results: Our study showed that the phenotype in TSC NMI individuals can be similar to those with heterozygous, particularly TSC1, variants. Although neurodevelopmental outcomes can be less severe, the number of organ systems involved was similar to the non-mosaic groups. A diagnostic yield of 72% (13/18) was achieved, with the majority (10/13) being mosaic variants and the remainder heterozygous variants missed on previous testing., Conclusion: Testing DNA from multiple tissue samples allowed for validation of otherwise discarded low-level mosaic variants and detection of mosaic variants by MPS without excessive cost or the need for specialised techniques. Implementing this approach in a diagnostic setting is viable and allows optimal clinical care of patients with NMI TSC., (© 2024 The Author(s).

Background: There is inconsistent evidence regarding the effect of birth parent substance use on developmental outcomes for children placed into out-of-home-care (OOHC)., Objective: This study aims to examine how parental substance use affects outcomes of Australian children in out-of-home care, adjusting for key demographic, social and system factors., Participants and Setting: Four waves of survey data were collected for children and young people who agreed to participate in the Pathways of Care Longitudinal Study (POCLS) between 2011 and 2018. The study sample included 1,506 children and young people (792 with a history of parental substance misuse) aged 9 months to 17 years who participated in at least one wave of the POCLS and had linked administrative data from the Department of Communities and Justice (DCJ), NSW, Australia., Methods: Multilevel longitudinal models were used to analyse the relationship of child developmental outcomes (physical health, socio-emotional wellbeing, and verbal and non-verbal cognitive ability) with parental substance misuse in their child protection history. Each model included adjustments for child demographics, family socio-economic status, child protection system factors and the unbalanced panel., Results: Children in OOHC with a history of parental substance misuse were more likely to be in the typical range for verbal cognitive development compared to those in OOHC without this history. In addition, younger (9 months to 5 years) children with a record of parental substance misuse exhibited significantly more typical fine and gross motor skill development than those without this history., Conclusions: Concerns that children in OOHC with a history of parental substance misuse may be more affected with regards to early-stage physical development, and later verbal cognitive development than those without this history in OOHC, may not be justified., Competing Interests: Declaration of competing interest The authors declare they have no conflicts of interest., (Copyright © 2024.

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., (© 2024 The Authors.

Objective: This study aims to analyse the clinical presentation caused by enterovirus (EV) and/or human parechovirus (HPeV) infection in children, as well as the management of such cases admitted to a regional hospital in Australia., Methods: Retrospective study reviewing medical records., Setting: Single hospital in regional Australia., Participants: All children under 18 years admitted over the 5-year period beginning from 1 January 2017 with confirmed EV and/or HPeV infection. Cases with clinically insignificant EV/HPeV isolation were excluded., Main Outcome Measures: Data collected included demographic data, signs and symptoms present, specimens of EV/HPeV isolation, co-occurring pathogens, peak C-reactive protein (CRP), antibiotic therapy, discharge diagnosis and follow-up after discharge., Results: Overall, 27 patients fulfilled the inclusion criteria; 81.5% of the patients were ≤3 months of age with a median of 2 months (interquartile range 1-3); 74.1% were males. The most common clinical features were a fever ≥38°C and irritability/lethargy/high-pitched cry. 29.6% of the patients had co-occurring pathogens detected, and a CRP ≤10 mg/L was observed in 77.8% of cases. All but two children were treated with antibiotics while awaiting polymerase chain reaction results. The most common discharge diagnosis was meningitis. In all, 74.1% of the children attended follow-up appointments., Conclusions: EV and HPeV should be considered as a possible aetiology of fever and irritability/lethargy/high-pitched cry in children under 3 months., (© 2024 National Rural Health Alliance Ltd..)

Mobile health (mHealth) interventions provide a low-cost, scalable approach to supporting parents with infant feeding advice with the potential to reduce health care visits and associated costs for infant feeding support. This Australian study examined the impact of the Growing healthy (GH) app on health service utilisation and out-of-pocket costs for families in the first 9 months of their infants life. A quasi-experimental study with a comparison group was conducted in 2015-2016 with an mHealth intervention group (GH app, n = 301) and a nonrandomized usual care group (n = 344). The GH app aimed to support parents of young infants with healthy infant feeding behaviours from birth to 9 months of age. App-generated notifications directed parents to age-and feeding-specific content within the app. Both groups completed surveys at baseline when infants were less than 3 months old (T1), at 6 months (T2) and 9 months (T3) of age. At T3, participants reported health services used and any out-of-pocket costs for advice on infant feeding, growth or activity. App users had lower odds (odds ratio: 0.38 95% confidence interval: 0.25, 0.59) of using one or more services and had lower number of visits to a general practitioner (1.0 vs. 1.5 visits, p = 0.003) and paediatrician (0.3 vs. 0.4 visits, p = 0.049) compared to the usual care group. There was no difference in out-of-pocket costs between groups. Provision of an evidenced-based infant feeding app may provide substantial savings to the health system and potentially to parents through fewer primary health care and paediatrician visits., (© 2024 The Authors.

Objectives: Nitrogen isotopes (δ 15 N) are widely used to study human nursing and weaning ages. Conventional methods involve sampling 1-mm thick sections of tooth dentine-producing an averaging effect that integrates months of formation. We introduce a novel protocol for measuring δ 15 N by multicollector secondary ion mass spectrometry (SIMS)., Materials and Methods: We sampled dentine δ 15 N on a weekly to monthly basis along the developmental axis in two first molars of healthy children from Australia and New Zealand (n = 217 measurements). Nitrogen isotope ratios were determined from measurements of CN - secondary molecular ions in ~35 μm spots. By relating spot position to enamel formation, we identified prenatal dentine, as well as sampling ages over more than 3 years. We also created calcium-normalized barium and strontium maps with laser ablation-inductively coupled plasma-mass spectrometry., Results: We found rapid postnatal δ 15 N increases of ~2‰-3‰, during which time the children were exclusively breastfed, followed by declines as the breastfeeding frequency decreased. After weaning, δ 15 N values remained stable for several months, coinciding with diets that did not include meat or cow's milk; values then varied by ~2‰ starting in the third year of life. Barium did not show an immediate postnatal increase, rising after a few months until ~1-1.5 years of age, and falling until or shortly after the cessation of suckling. Initial strontium trends varied but both individuals peaked months after weaning., Discussion: Developmentally informed SIMS measurements of δ 15 N minimize time averaging and can be precisely related to an individual's early dietary history., (© 2024 The Author(s).

Introduction: Many experts and communities have concerns about how National Disability Insurance Scheme services are provided to Aboriginal and Torres Strait children. This study was undertaken at the request of the NPY Women's Council in partnership with the researchers, to explore supports for Aboriginal and Torres Strait Islander children living with a disability in their remote areas., Objective: This scoping review aims to (a) explore the barriers and enablers to accessing disability support services for families of young Aboriginal and Torres Strait Islander children (0-8 years) living in regional, rural and remote settings, and (b) summarise best practice approaches for accessing support for young children in these settings., Design: The search was run in three electronic databases, as well as grey literature sources. We assessed the quality of included publications using the Centre of Research Excellence in Aboriginal Chronic Disease Knowledge Translation and Exchange tool. A narrative synthesis was supported by thematic analysis., Findings: From an initial search (557 citations), we identified 13 eligible documents. Most documents were peer-reviewed articles of qualitative studies. Key themes identified included the following: (1) Holistic approach, (2) Understanding disability, (3) Consistent relationships, (4), Flexibility, (5) Simplify system and (6) Enhance communication., Discussion/conclusion: This scoping review has revealed gaps in the provision of quality, culturally responsive disability services for families of Aboriginal and Torres Strait Islander children living in regional, rural and remote areas of Australia. A family-centred, flexible approach will help address their needs. Future research is required to design and evaluate models of care for Aboriginal and Torres Strait Islander children., (© 2024 The Author(s).

Introduction: In occupational therapy for children, collaborative practice with parents is crucial for meaningful family-centred interventions, yet it remains undefined and inconsistently addressed. This study aimed to establish foundational concepts for collaborative practice with parents in occupational therapy for children in progressing the field with a universal description., Methods: This paper encompasses the second dataset of a larger scoping review and a preliminary validation of findings by an advisory panel. Data were gathered from indexed sources on collaborative practice with parents in occupational therapy for children (ages 0-10) using MedLine, PsychInfo, ERIC, Embase, OTSeeker, Scopus, and ProQuest Central. Data were extracted, charted, and descriptively analysed by paired independent reviewers. The Joanna Briggs Institute Manual and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis-extension for Scoping Reviews were used. A draft definition of collaborative practices, developed based on preliminary review findings and an operational definition, was validated by an advisory panel of 13 experienced Australian occupational therapists, whose input was integrated into a final, comprehensive description of collaborative practice., Results: The scoping review encompassed 299 sources, revealing three major components of collaborative practice: 'collaborative practice aims', 'parent-therapist partnership', and 'strategies for collaboration'. The advisory panel endorsed the draft definition, confirmed its professional relevance, and suggested some modifications., Conclusion: The major outcome of this study is an evidence-based and discipline-specific preliminary description of collaborative practice with parents in occupational therapy for children. This description provides a common language and foundational concepts for the future development of a collaborative practice framework to guide practice and research. Future studies can explore specific components, exploring their mechanisms and significance. Further expanded validation is required, incorporating the perspectives of a wider community of occupational therapists and families to enhance the description's applicability., (© 2024 The Authors.

Objectives: We evaluated the extent of virus heterogeneity in PeV infected infants in the UK, Canada and Australia., Methods: Samples were collected from PeV infected infants during 2013-16. Next generation sequencing was used to obtain sequencing data and construct phylogenetic trees based on analysis of the VP1 region. Comparison was made with sequencing data available from an outbreak in Australia., Results: We amplified and sequenced 58 samples. All obtained PeV sequences were genotype 3 apart from one UK sample which was PeV-A5. Phylogenetic analysis revealed that all strains clustered together on the same clade and showed no significant genetic variation. We saw no significant evidence of association between sequence and either clinical severity (defined by admission to paediatric intensive care), geographical origin (compared between Canada and U.K) or year of sample collection (samples sequenced during 2013 - 2018)., Conclusions: In this small cohort, sequencing data indicate that PeV circulating in the UK and Canada from 2013 to 18 are derived from a common ancestor. No association between disease severity and genetic sequence was seen in the UK or Canadian cohorts. Larger studies are required to support these findings., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background: Event-free survival (EFS) considers other adverse events in addition to mortality. It therefore provides a more complete understanding of the effectiveness and consequences of treatment than standard survival measures, but is rarely reported at the population level for childhood cancer., Procedure: Our study cohort (n = 7067) was obtained from the Australian Childhood Cancer Registry, including children aged under 15 diagnosed with cancer between 2006 and 2015, with follow-up potentially available to 31 December 2020. The events of interest were relapse following remission, progressive disease, diagnosis of a second primary cancer or death from any cause. Five-year EFS and all-cause observed survival were both calculated, stratified by type of childhood cancer, remoteness of residence and stage at diagnosis. Differences in EFS were assessed using multivariable flexible parametric models., Results: Approximately one quarter of patients (n = 1605 of 7067, 23%) experienced at least one of the events of interest within 5 years of diagnosis. Relapse was twice as common for children with metastatic/advanced disease (22%) versus children with localised/limited cancers (11%). Overall 5-year EFS was 75.0% (95% confidence interval [CI]: 73.9%-76.0%), compared to 85.8% observed survival (95% CI: 85.0%-86.6%). Patients with other gliomas had the lowest EFS (35.4%, 95% CI: 27.8%-43.1%). EFS was significantly lower among children with acute myeloid leukaemia in outer regional/remote areas compared to major cities (adjusted hazard ratio [HR] = 1.90, 95% CI: 1.20-3.00)., Conclusions: Reporting EFS at a population level provides further insight on a wider range of impacts apart from mortality alone, contributing towards efforts to improve the management and outcomes of childhood cancer., (© 2024 Wiley Periodicals LLC.)
