Childhood obesity rates in the UK are high. The early years of childhood are critical for establishing healthy behaviours and offer interventional opportunities. We aimed to identify studies evaluating the impact of UK-based obesity interventions in early childhood.

Systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Nine databases were searched in March 2023. Eligibility criteria: We included UK-based obesity intervention studies delivered to children aged 6 months to 5 years that had diet and/or physical activity components and reported anthropometric outcomes. The primary outcome of interest was z-score Body Mass Index (zBMI) change (within and between subjects). Studies evaluating the effects of breastfeeding interventions were not included as obesity prevention interventions, given that best-practice formula feeding is also likely to encourage healthy growth. The publication date for studies was limited to the previous 12 years (2011–23), as earlier reviews found few evaluations of interventions in the UK.

The reviewers worked independently using standardised approach to search, screen and code the included studies. Risk of bias was assessed using Cochrane tools (ROB 2 or ROBINS-I).

Six trials (five studies) were identified, including two randomised controlled trials (RCT), one cluster randomised trial (CRT), two feasibility CRTs and one impact assessment. The total number of participants was 566. Three trials focused on disadvantaged families and two included high-risk children categorised as having overweight or obesity. Compared with baseline, five interventions reported reductions in zBMI, three of which were statistically significant (p

UK evidence was limited but some interventions showed promising results in promoting healthy growth. As part of a programme of policies, interventions in the early years may have an important role in reducing the risk of childhood obesity.

Patient engagement and integrated knowledge translation (iKT) processes improve health outcomes and care experiences through meaningful partnerships in consensus-building initiatives and research. Consensus-building is essential for engaging a diverse group of experienced knowledge users in co-developing and supporting a solution where none readily exists or is less optimal. Patients and caregivers provide invaluable insights for building consensus in decision-making around healthcare, policy and research. However, despite emerging evidence, patient engagement remains sparse within consensus-building initiatives. Specifically, our research has identified a lack of opportunity for youth living with chronic health conditions and their caregivers to participate in developing consensus on indicators/benchmarks for transition into adult care. To bridge this gap and inform our consensus-building approach with youth/caregivers, this scoping review will synthesise the extent of the literature on patient and other knowledge user engagement in consensus-building healthcare initiatives.

Following the scoping review methodology from Joanna Briggs Institute, published literature will be searched in MEDLINE, EMBASE, CINAHL and PsycINFO databases from inception to July 2023. Grey literature will be hand-searched. Two independent reviewers will determine the eligibility of articles in a two-stage process, with disagreements resolved by a third reviewer. Included studies must be consensus-building studies within the healthcare context that involve patient engagement strategies. Data from eligible studies will be extracted and charted on a standardised form. Abstracted data will be analysed quantitatively and descriptively, according to specific consensus methodologies, and patient engagement models and/or strategies.

Ethics approval is not required for this scoping review protocol. The review process and findings will be shared with and informed by relevant knowledge users. Dissemination of findings will also include peer-reviewed publications and conference presentations. The results will offer new insights for supporting patient engagement in consensus-building healthcare initiatives.

During the preschool years, children depend on adult caregivers to provide opportunities for physical activity (PA). Research has focused on measuring PA in preschool, as well as barriers and facilitators to children’s PA but caregiver perceptions remain largely unknown especially in light of the COVID-19 pandemic. This study aims to understand the value of PA in preschool following the pandemic from three types of adult caregivers, parents of a young child (n=7), preschool teachers (n=7) and preschool administrators (n=7).

In-depth qualitative interviews were conducted to explore the following research questions: (a) how do caregivers describe the importance of PA in preschool postpandemic? (b) how do caregivers support and prioritise PA in preschool postpandemic and what challenges do they face in doing so? and (c) how do caregivers interact with one another to promote PA? Qualitative answers were coded using a codebook developed to answer the research questions of interest.

Parents, teachers and administrators all described valuing PA for preschoolers, but each caregiver type described a different way of promoting it. All the caregivers listed barriers that inhibit their ability to prioritise and promote PA, some heightened postpandemic. Lastly, there were limited caregiver interactions when it came to promoting PA, with the burden largely falling on teachers.

Our findings indicate that one particularly important area for intervention is supporting parents, teachers and preschool administrators in creating a shared understanding of the importance of PA for young children and ways to collaborate to promote it.

Paediatricians perform medical assessments for children in cases of suspected child maltreatment. Due to their role with statutory child protection agencies and police, paediatricians may be asked to testify in court about child protection and criminal justice matters. To the authors’ knowledge, there has been no previous systematic review of the literature synthesising the evidence on the impacts on paediatricians testifying in cases of child maltreatment.

A search strategy comprising indexed and key terms will be applied to six electronic reference databases from inception to May 2023: Medline, EMBASE, PsycINFO, CINAHL, Criminal Justice Abstracts and Cochrane Library. Two reviewers will independently screen titles and abstracts and full-text articles against predefined eligibility criteria to identify studies of interest. Conflicts will be independently adjudicated by a third reviewer.

Since the systematic review methodology aims at synthesising information from available publications, this study does not require ethical approval. An article reporting the results of the systematic review will be submitted for publication in a scientific journal, presented at relevant conferences and used in subsequent stakeholder consultations.

Fetal alcohol spectrum disorder (FASD) is a neurodevelopmental disorder caused by alcohol exposure during pregnancy. FASD is associated with neurodevelopmental deviations, and 50%–94% of children with FASD meet the Diagnostic and Statistical Manual of Mental Disorders-fifth edition diagnostic criteria for attention deficit hyperactivity disorder (ADHD). There is a paucity of evidence around medication efficacy for ADHD symptoms in children with FASD. This series of N-of-1 trials aims to provide pilot data on the feasibility of conducting N-of-1 trials in children with FASD and ADHD.

A pilot N-of-1 randomised trial design with 20 cycles of stimulant and placebo (four cycles of 2-week duration) for each child will be conducted (n=20) in Melbourne, Australia.

Feasibility and tolerability will be assessed using recruitment and retention rates, protocol adherence, adverse events and parent ratings of side effects. Each child’s treatment effect will be determined by analysing teacher ADHD ratings across stimulant and placebo conditions (Wilcoxon rank). N-of-1 data will be aggregated to provide an estimate of the cohort treatment effect as well as individual-level treatment effects. We will assess the sample size and number of cycles required for a future trial. Potential mediating factors will be explored to identify variables that might be associated with treatment response variability.

The study was approved by the Hospital and Health Service Human Research Ethics Committee (HREC/74678/MonH-2021-269029), Monash (protocol V6, 25 June 2023).

Individual outcome data will be summarised and provided to participating carers and practitioners to enhance care. Group-level findings will be presented at a local workshop to engage stakeholders. Findings will be presented at national and international conferences and published in peer-reviewed journals. All results will be reported so that they can be used to inform prior information for future trials.

This study aimed to understand how staff in children’s hospitals view their responsibility to reduce health inequalities for the children and young people who access their services.

We conducted an exploratory qualitative study.

The study took place at nine children’s hospitals in England.

217 members of staff contributed via interviews and focus groups conducted January–June 2023. Staff were represented at all levels of the organisations, and all staff who volunteered to contribute were included in the study.

Data were analysed using Rapid Research Evaluation and Appraisal (RREAL) methodology for rapid assessment procedures (RAP).

All of the children’s hospitals were taking some action to reduce health inequalities. Two key themes were identified. First, it was clear that reducing health inequalities was seen as something that was of vital import and should be part of staff’s day-to-day activity, framed as ‘everyone’s business.’ Many staff felt that there was an obligation to intervene to ensure that children and young people receiving hospital treatment were not further disadvantaged by, for example, food poverty. Second, however, the deeply entrenched and intersectional nature of health inequalities sometimes meant that these inequalities were complex to tackle, with no clear impetus to specific actions, and could be framed as ‘no-one’s responsibility’. Within a complex health and social care system, there were many potential actors who could take responsibility for reducing health inequalities, and staff often questioned whether it was the role of a children’s hospital to lead these initiatives.

Broadly speaking, senior leaders were clear about their organisational role in reducing health inequalities where they impacted on access and quality of care, but there was some uncertainty about the perceived boundaries of responsibility. This led to fragility in the sustainability of activity, and a lack of joined-up intervention. Most hospitals were forging ahead with activity, considering that it was more important to work to overcome health inequalities rather than debate whose job it was.

The paediatric population represents a quarter of the world’s population, and like adult patients, they have also suffered immeasurably from the SARS-CoV-2 pandemic. Immunisation is an effective strategy for reducing the number of COVID-19 cases. With the advancements in vaccination for younger age groups, parents or guardians have raised doubts and questions about adverse effects and the number of doses required. Therefore, systematic reviews focusing on this population are needed to consolidate evidence that can help in decision-making and clinical practice. This protocol aims to assess the safety of COVID-19 vaccines in paediatric patients and evaluate the correlation between the number of vaccine doses and side effects.

We will search the PubMed, ClinicalTrials.gov, Web of Science, Embase, CINAHL, Latin American and Caribbean Health Sciences Literature, Scopus and Cochrane databases for randomised and quasi-randomised clinical trials that list the adverse effects of the COVID-19 vaccine and assess its correlation with the number of doses, without any language restrictions. Two reviewers will select the studies according to the inclusion and exclusion criteria, extract data and asses for risk of bias using the Cochrane risk-of-bias tool. The Review Software Manager (RevMan V.5.4.1) will be used to synthesise the data. We will use the Working Group’s Grading of Recommendations Assessment, Development and Evaluations to grade the strength of the evidence of the results.

Formal ethical approval is not required as no primary data are collected. This systematic review will be disseminated through a peer-reviewed publication.

Children with sickle cell disease show a significant decrease in bone mineral density, an increase in resting energy expenditure of more than 15%, a decrease in fat and lean mass as well as a significant increase in protein turnover, particularly in bone tissue. This study aims to evaluate the effectiveness of an increase in food intake on bone mineral density and the clinical and biological complications of paediatric sickle cell disease.

The study is designed as an open-label randomised controlled clinical trial conducted in the Paediatrics Unit of the Orléans University Hospital Centre. Participants aged 3–16 years will be randomly divided into two groups: the intervention group will receive oral nutritional supplements (pharmacological nutritional hypercaloric products) while the control group will receive age-appropriate and gender-appropriate nutritional intake during 12 months. Total body less head bone mineral density will be measured at the beginning and the end of the trial. A rigorous nutritional follow-up by weekly 24 hours recall dietary assessment and planned contacts every 6 weeks will be carried out throughout the study. A school absenteeism questionnaire, intended to reflect the patient’s school productivity, will be completed by participants and parents every 3 months. Blood samples of each patient of both groups will be stocked at the beginning and at the end of the trial, for future biological trial. Clinical and biological complications will be regularly monitored.

The protocol has been approved by the French ethics committee (Comité de Protection des Personnes Sud-Ouest et Outre-Mer 2, Toulouse; approval no: 2-20-092 id9534). Children and their parents will give informed consent to participate in the study before taking part. Results will be disseminated through peer-reviewed journals or international academic conferences.

Severe community-acquired pneumonia (SCAP) is a significant cause of morbidity worldwide and a major cause of morbidity and mortality in developing countries. Ethiopia ranks 6th out of 15 countries with the highest mortality rate due to pneumonia in children under 5 years of age. The aim of this study was to determine the recovery time from SCAP and factors in paediatric patients in selected hospitals in Addis Ababa.

A retrospective cohort study was conducted among 407 randomly selected paediatric patients admitted with SCAP in Addis Ababa public hospitals from 1 January 2018 to 31 December 2020.

Recovery time and recovery rate from SCAP were estimated using Kaplan-Meier and simple frequency statistics, respectively, and the adjusted HR with a 95% CI was used to identify associated factors for recovery.

91.5% (95% CI: 88.3% to 94.1%) of children recovered from SCAP with an overall recovery rate of 11.5 (95% CI: 10.37 to 12.76) per 100 person-day observation, and the median recovery time was 6 days. In the multivariable analysis, older age and the absence of comorbidities were protective factors for early recovery, while stunting and late utilisation of medical care were risk factors.

The median recovery time after SCAP was very long compared with the optimal recovery time of 3 days given in the British Thoracic Society guidelines. Older age and absence of comorbidities were found to shorten recovery time, whereas stunting and late initiation of treatment delayed recovery. Therefore, measures that increase the recovery rate and shorten the recovery time, such as primary prevention to eliminate malnutrition and increase the utilisation of medical care in the community, should be strengthened, and health workers should focus on the early detection and treatment of comorbid diseases.

Investigate the association between the dietary diversity of preschool children and proximate factors including household food insecurity, maternal food choice, preferences, khat use, and levels of depressive symptoms.

Cross-sectional survey of randomly selected households.

Haramaya Health and Demographic Surveillance site in Eastern Ethiopia, predominantly smallholder farming households.

678 preschool children (24–59 months) and their mothers.

The key outcome, the adequacy of dietary diversity of preschool children, was calculated using a 24-hour parental dietary recall. Binary logistic regression was then used to identify maternal and household factors associated with dietary adequacy versus inadequacy.

The majority (80.53%) of surveyed children had low dietary diversity (mean Dietary Diversity (MDD)) score of 3.06±1.70 on a 7-point scale). Approximately 80% of households exhibited food insecurity. Households with greater food security (adjusted OR (AOR)=1.96, 95% CI 1.19 to 3.23), healthier maternal food choice (AOR=2.19, 95% CI 1.12 to 4.31) and broader maternal food preferences (AOR=4.95, 95% CI 1.11 to 21.95) were all associated with higher dietary diversity of their preschool children (p≤0.05). Other covariates associated with adequate child dietary diversity included improved household drinking water sources (AOR=1.84, 95% CI 1.16 to 2.92) and family planning use (AOR=1.69, 95% CI 1.00 to 2.86). Despite predictions, however, maternal depression and khat consumption were not identified as factors.

The dietary diversity of preschool children is extremely low—a pattern observed in both food-secure and food-insecure households. Key factors include maternal selection of food for convenience and ease, preferences that do not include animal protein or healthier food choices, and lack of access to improved drinking water sources. Interventions around maternal food choice and preferences could improve preschool children’s nutritional health.

Diffuse intrinsic pontine glioma (DIPG) and paediatric high-grade glioma (pHGG) are aggressive glial tumours, for which conventional treatment modalities fall short. Dendritic cell (DC)-based immunotherapy is being investigated as a promising and safe adjuvant therapy. The Wilms’ tumour protein (WT1) is a potent target for this type of antigen-specific immunotherapy and is overexpressed in DIPG and pHGG. Based on this, we designed a non-randomised phase I/II trial, assessing the feasibility and safety of WT1 mRNA-loaded DC (WT1/DC) immunotherapy in combination with conventional treatment in pHGG and DIPG.

10 paediatric patients with newly diagnosed or pretreated HGG or DIPG were treated according to the trial protocol. The trial protocol consists of leukapheresis of mononuclear cells, the manufacturing of autologous WT1/DC vaccines and the combination of WT1/DC-vaccine immunotherapy with conventional antiglioma treatment. In newly diagnosed patients, this comprises chemoradiation (oral temozolomide 90 mg/m² daily+radiotherapy 54 Gy in 1.8 Gy fractions) followed by three induction WT1/DC vaccines (8–10x10⁶ cells/vaccine) given on a weekly basis and a chemoimmunotherapy booster phase consisting of six 28-day cycles of oral temozolomide (150–200 mg/m² on days 1–5) and a WT1/DC vaccine on day 21. In pretreated patients, the induction and booster phase are combined with best possible antiglioma treatment at hand. Primary objectives are to assess the feasibility of the production of mRNA-electroporated WT1/DC vaccines in this patient population and to assess the safety and feasibility of combining conventional antiglioma treatment with the proposed immunotherapy. Secondary objectives are to investigate in vivo immunogenicity of WT1/DC vaccination and to assess disease-specific and general quality of life.

The ethics committee of the Antwerp University Hospital and the University of Antwerp granted ethics approval. Results of the clinical trial will be shared through publication in a peer-reviewed journal and presentations at conferences.

Children with cerebral palsy (CP) are prescribed home exercise programmes (HEPs) to increase the frequency of movement practice, yet adherence to HEPs can be low. This paper outlines the protocol for a single-case experimental design (SCED) with alternating treatments, using a new home therapy exercise application, Bootle Boot Camp (BBCamp), offered with and without movement tracking feedback. This study will explore the impact of feedback on engagement, movement quality, lower limb function and family experiences to help understand how technology-supported HEPs should be translated and the added value, if any, of movement tracking technology.

In this explanatory sequential mixed-methods study using a SCED, 16 children with CP (aged 6–12 years, Gross Motor Function Classification System levels I–II) will set lower limb goals and be prescribed an individualised HEP by their physiotherapist to complete using BBCamp on their home television equipped with a three-dimensional camera-computer system. Children will complete four weekly exercise sessions over 6 weeks. Children will be randomised to 1 of 16 alternating treatment schedules where BBCamp will provide or withhold feedback during the first 4 weeks. The version of BBCamp that results in the most therapeutic benefit will be continued for 2 final weeks. Goals will be re-evaluated and families interviewed. The primary outcome is adherence (proportion of prescribed exercise repetitions attempted) as a measure of behavioural engagement. Secondary outcomes are affective and cognitive engagement (smiley face ratings), exercise fidelity, lower limb function, goal achievement and participant experiences. SCED data will be analysed using visual and statistical methods. Quantitative and qualitative data will be integrated using joint displays.

Ethical approval was obtained from the Research Ethics Boards at Bloorview Research Institute and the University of Toronto. Results will be distributed through peer-reviewed journals and scientific conferences.

Alport syndrome (AS) is one of the most common fatal hereditary renal diseases in human, with a high risk of progressing to end-stage renal disease without effective treatments. Mesenchymal stem cells (MSCs) have recently emerged as a promising therapeutic strategy for chronic kidney disease. However, the safety and therapeutic potential of MSC transfusion for patients with AS are still need to be confirmed. Therefore, we have designed a clinical trial to evaluate the hypothesis that intravenous infusion of human umbilical cord-derived MSC (hUC-MSC) is safe, feasible, and well-tolerated in children with AS.

We report the protocol of the first prospective, open-label, single-arm clinical trial to evaluate the safety and preliminary efficacy of hUC-MSC transfusion in children with early-stage AS. Paediatric patients diagnosed with AS who have persistent albuminuria will be candidates for screening. Twelve eligible patients are planned to recruit and will receive hUC-MSC infusions under close safety monitoring, and complete the efficacy assessments at scheduled follow-up visits. The primary endpoints include the occurrence of adverse events to assess safety and the albuminuria level for efficacy evaluation. Secondary endpoint assessments are based on haematuria and glomerular filtration measurements. Each patient’s efficacy endpoints will be evaluated against their baseline levels. Additionally, the underlying mechanism of hUC-MSC therapy will be explored through transcriptomic and proteomic analysis of blood and urine samples.

The protocol (V.1.0, date 17 January 2015) was approved by the institutional review board of the Affiliated Taihe Hospital of Hubei University of Medicine (ethical approval 03 March 2015). Written informed consent will be obtained from the patient and/or guardians before study specific process. In addition to publication in a peer-reviewed scientific journal, a lay summary of study will be available for participants and the public on the Chinese Organization for Rare Disorders website (http://www.cord.org.cn/).

To explore associations between adverse birth outcomes and childhood overweight at 3–8 years of age.

A prospective cohort study.

Six central urban districts of Tianjin, China.

1681 woman–child pairs.

1681 woman–child pairs were followed up for 8 years in Tianjin, China. Demographic and clinical information including birth outcomes was collected longitudinally, commencing from first antenatal care visit till postpartum period. Offspring height and weight were measured at 3–8 years of age. High and low weight/length ratios (WLR) at birth were, respectively, defined as ≥90th and ≤10th gestational week and sex-specific percentiles. Overweight for children at 3–5 and 6–8 years of age were, respectively, defined as body mass index (BMI)-for-age and -sex above the 2 z-score and 1 z-score curves of the WHO’s child growth standards. Binary logistic regression analysis was used to obtain ORs and 95% CI with a stepwise backward selection method to select independent predictors.

Childhood overweight.

Of 1681 children, 10.7% (n=179) and 27.8% (n=468) developed overweight at 3–5 and 6–8 years of age, respectively. Large for gestational age (LGA) was associated with increased risk of overweight at 3–5 years of age (aOR: 1.86, 95% CI: 1.27 to 2.72) while high WLR at birth was associated with increased risk of overweight at 6–8 years of age (1.82, 1.41 to 2.34). Low WLR at birth was associated with decreased risk of overweight at 6–8 years of age (0.52, 0.30 to 0.90).

LGA and high WLR at birth predicted childhood overweight at 3–5 and 6–8 years of age, respectively. Low WLR at birth was associated with decreased risk of childhood overweight at 6–8 years of age.

The aim was to evaluate whether standardised exercise performance during the incremental shuttle walk test (ISWT) can be used to assess disease severity in children and young people (CYP) with chronic conditions, through (1) identifying the most appropriate paediatric normative reference equation for the ISWT, (2) assessing how well CYP with haemophilia and cystic fibrosis (CF) perform against the values predicted by the best fit reference equation and (3) evaluating the association between standardised ISWT performance and disease severity.

A cross-sectional analysis was carried out using existing data from two independent studies (2018–2019) at paediatric hospitals in London,UK. CYP with haemophilia (n=35) and CF (n=134) aged 5–18 years were included. Published reference equations for standardising ISWT were evaluated through a comparison of populations, and Bland-Altman analysis was used to assess the level of agreement between distances predicted by each equation. Associations between ISWT and disease severity were assessed with linear regression.

Three relevant reference equations were identified for the ISWT that standardised performance based on age, sex and body mass index (Vardhan, Lanza, Pinho). A systematic proportional bias of standardised ISWT was observed in all equations, most pronounced with Vardhan and Lanza; the male Pinho equation was identified as most appropriate. On average, CYP with CF and haemophilia performed worse than predicted by the Pihno equation, although the range was wide. Standardised ISWT, and not ISWT distance alone, was significantly associated with forced expiratory volume in 1 s in CYP with CF. Standardised ISWT in CYP with haemophilia was slightly associated with haemophilia joint health score, but this was not significant.

ISWT performance may be useful in a clinic to identify those with worsening disease, but only when performance is standardised against a healthy reference population. The development of validated global reference equations is necessary for more robust assessment.

The overall objective of the study was to describe the disposition status of children presenting with a burn injury to five emergency departments (ED) across New South Wales (NSW), Australia.

A retrospective study design was used to review routinely collected ED data.

Study sites included five acute hospitals across NSW, Australia.

During the 5-year study period between 1 January 2015 to 31 December 2020, there were 5213 paediatric burn injury presentations.

The mean age of burn injury presentations was 24 months (Inter-Quartile-Range (IQR) 12–84), of which 57% (2951/5213) were males. The most common presentation time was between 16:00 and 23:59 hours (63%, 3297/5213), and the median time spent in the ED was 3 hours (IQR 1–4). The majority (80%, 4196/5213) of the burn injuries presentations did not require hospital admission. The most common principal diagnoses were ‘Burn body region unspecified’ (n=1916) and ‘Burn of wrist and hand’ (n=1060).

Most children who presented to the hospital with a burn injury were not admitted. Often the details of these burns were poorly recorded and a complete picture of the true burden of burn injury in children, especially the ongoing care given outside the acute hospital setting, is missing. This information is crucial, as it would inform future models of care as the paradigm shifts rapidly towards primary, ambulatory and outpatient models of care.

Birth injury is a significant public health problem in Africa, with a high incidence and associated mortality and morbidity. Systematic reviews that indicate the incidence, contributing factors and outcomes of birth injury in Africa provide valuable evidence to policy-makers and programme planners for improving prevention and treatment strategies. Therefore, this review is aimed to evaluate the incidence, contributing factors and outcomes of birth injury among newborns in Africa.

The data will be searched and extracted from JBI Database, Cochrane Database, MEDLINE/PubMed, CINAHL/EBSCO, EMBASE, PEDro, POPLINE, Proquest, OpenGrey (SIGLE), Google Scholar, Google, APA PsycInfo, Web of Science, Scopus and HINARI. Unpublished studies and grey literature will be searched from different sources. This systematic review will include quantitative observational studies, registry and census data, and experimental studies that report on the prevalence or incidence in Africa from 1 January 1990 to 30 September 2023. The Joanna Briggs Institute (JBI) quality appraisal checklist will be used to select eligible studies. Two researchers will independently appraise and extract the data from included studies and resolve discrepancies through discussion. Heterogeneity will be assessed using forest plots and the I² statistic. If substantial heterogeneity is present, a random-effects model will be used to pool the data. Subgroup analyses will be used to explore the potential sources of heterogeneity. Publication bias will be assessed using funnel plots and Egger’s regression test. The software package used to conduct the meta-analysis will be JBI SUMARI. An association will be considered significant if the p

Ethical clearance is not needed for this systematic review and the results will be shared with relevant stakeholders to maximise reach and impact.

To evaluate the feasibility of using the NeuroMotion smartphone application for remote General Movements Assessment for screening infants for cerebral palsy in Kathmandu, Nepal.

Thirty-one term-born infants at risk of cerebral palsy due to birth asphyxia or neonatal seizures were recruited for the follow-up at Paropakar Maternity and Women’s Hospital, 1 October 2021 to 7 January 2022. Parents filmed their children at home using the application at 3 months’ age and the videos were assessed for technical quality using a standardised form and for fidgety movements by Prechtl’s General Movements Assessment. The usability of the application was evaluated through a parental survey.

Twenty families sent in altogether 46 videos out of which 35 had approved technical quality. Sixteen children had at least one video with approved technical quality. Three infants lacked fidgety movements. The level of agreement between assessors was acceptable (Krippendorf alpha 0.781). Parental answers to the usability survey were in general positive.

Engaging parents in screening of cerebral palsy with the help of a smartphone-aided remote General Movements Assessment is possible in the urban area of a South Asian lower middle-income country.

Bronchiolitis is the most common viral lower respiratory tract infection in children under 2 years of age. Respiratory support with high-flow nasal cannula (HFNC) is increasingly used in this patient population with limited understanding of the patients most likely to benefit and considerable practice variability of use. This study aims to understand the factors associated with failure of HFNC support among patients with bronchiolitis and to describe the current practice variations of HFNC use in patients with bronchiolitis in Canadian hospitals including fluid management and parameters to initiate, escalate and discontinue HFNC support.

This is a multicentre retrospective cohort study including hospitalised patients aged 0–24 months with bronchiolitis requiring support with HFNC between January 2017 and December 2021. Clinical data will be collected from patient medical records from Canadian hospitals (n=12), including academic and community centres. HFNC failure will be defined as the need for escalation to non-invasive or invasive mechanical ventilation. Factors associated with HFNC failure will be analysed using logistic regression. Descriptive statistics will be used to describe practice variations of HFNC utilisation and management.

Approval from the Research Ethics Boards (REBs) has been obtained for each participating study site prior to onset of data collection including Clinical Trials Ontario for all Ontario hospital sites and REBs from British Columbia Children’s Hospital, Stollery Children’s Hospital, Montreal Children’s Hospital and CHU Sainte-Justine. Study results will be disseminated through presentation at national/international conferences and publication in high-impact, peer-reviewed journals.

Cystic fibrosis (CF) is a life-limiting autosomal recessive genetic condition. It is caused by mutations in the gene that encodes for a chloride and bicarbonate conducting transmembrane channel. X-ray velocimetry (XV) is a novel form of X-ray imaging that can generate lung ventilation data through the breathing cycle. XV technology has been validated in multiple animal models, including the β-ENaC mouse model of CF lung disease. It has since been assessed in early-phase clinical trials in adult human subjects; however, there is a paucity of data in the paediatric cohort, including in CF. The aim of this pilot study was to investigate the feasibility of performing a single-centre cohort study in paediatric patients with CF and in those with normal lungs to demonstrate the appropriateness of proceeding with further studies of XV in these cohorts.

This is a cross-sectional, single-centre, pilot study. It will recruit children aged 3–18 years to have XV lung imaging performed, as well as paired pulmonary function testing. The study will aim to recruit 20 children without CF with normal lungs and 20 children with CF. The primary outcome will be the feasibility of recruiting children and performing XV testing. Secondary outcomes will include comparisons between XV and current assessments of pulmonary function and structure.

This project has ethical approval granted by The Women’s and Children’s Hospital Human Research Ethics Committee (HREC ID 2021/HRE00396). Findings will be disseminated through peer-reviewed publication and conferences.
