Pulmonary artery capacitance is a relatively novel measurement associated with adverse outcomes in pulmonary arterial hypertension. We sought to determine if preoperative indexed pulmonary artery capacitance was related to outcomes in paediatric heart transplant recipients, describe the changes in indexed pulmonary artery capacitance after transplantation, and compare its discriminatory ability to predict outcomes as compared to conventional predictors.

This was a retrospective study of paediatric patients who underwent heart transplant at our centre from July 2014 to May 2022. Variables from preoperative and postoperative clinical, catheterisation, and echo evaluations were recorded. The primary composite outcome measure included postoperative mortality, postoperative length of stay in the top quartile, and/or evidence of end organ dysfunction.

Of the 23 patients included in the analysis, 11 met the composite outcome. There was no statistical difference between indexed pulmonary artery capacitance values in patients who met the composite outcome [1.8 ml/mmHg/m2 (interquartile 0.8, 2.4)] and those who did not [1.4 (interquartile 0.9, 1.7)], p = 0.17. There were no significant signs of post-operative right heart failure in either group. There was no significant difference between pre-transplant and post-transplant indexed pulmonary artery capacitance or indexed pulmonary vascular resistance.

Preoperative pulmonary artery capacitance was not associated with our composite outcome in paediatric heart transplant recipients. It did not appear to be additive to pulmonary vascular resistance in paediatric heart transplant patients. Pulmonary vascular disease did not appear to drive outcomes in this group.

To examine the association of posttraumatic headache (PTH) type with postconcussive symptoms (PCS), pain intensity, and fluid cognitive function across recovery after pediatric concussion.

This prospective, longitudinal study recruited children (aged 8–16.99 years) within 24 hours of sustaining a concussion or mild orthopedic injury (OI) from two pediatric hospital emergency departments. Based on parent-proxy ratings of pre- and postinjury headache, children were classified as concussion with no PTH (n = 18), new PTH (n = 43), worse PTH (n = 58), or non-worsening chronic PTH (n = 19), and children with OI with no PTH (n = 58). Children and parents rated PCS and children rated pain intensity weekly up to 6 months. Children completed computerized testing of fluid cognition 10 days, 3 months, and 6- months postinjury. Mixed effects models compared groups across time on PCS, pain intensity, and cognition, controlling for preinjury scores and covariates.

Group differences in PCS decreased over time. Cognitive and somatic PCS were higher in new, chronic, and worse PTH relative to no PTH (up to 8 weeks postinjury; d = 0.34 to 0.87 when significant) and OI (up to 5 weeks postinjury; d = 0.30 to 1.28 when significant). Pain intensity did not differ by group but declined with time postinjury. Fluid cognition was lower across time in chronic PTH versus no PTH (d = −0.76) and OI (d = −0.61) and in new PTH versus no PTH (d = −0.51).

Onset of PTH was associated with worse PCS up to 8 weeks after pediatric concussion. Chronic PTH and new PTH were associated with moderately poorer fluid cognitive functioning up to 6 months postinjury. Pain declined over time regardless of PTH type.

Australian children fall short of national dietary guidelines with only 63 % consuming adequate fruit and 10 % enough vegetables. Before school care operates as part of Out of School Hours Care (OSHC) services and provides opportunities to address poor dietary habits in children. The aim of this study was to describe the food and beverages provided in before school care and to explore how service-level factors influence food provision.

A cross-sectional study was conducted in OSHC services. Services had their before school care visited twice between March and June 2021. Direct observation was used to capture food and beverage provision and child and staff behaviour during breakfast. Interviews with staff collected information on service characteristics. Foods were categorised using the Australian Dietary Guidelines, and frequencies were calculated. Fisher’s exact test was used to compare food provision with service characteristics.

The before school care of OSHC services in New South Wales, Australia.

Twenty-five OSHC services.

Fruit was provided on 22 % (n 11) of days and vegetables on 12 % (n 6). Services with nutrition policies containing specific language on food provision (i.e. measurable) were more likely to provide fruit compared with those with policies using non-specific language (P= 0·027). Services that reported receiving training in healthy eating provided more vegetables than those who had not received training (P= 0·037).

Before school care can be supported to improve food provision through staff professional development and advocating to regulatory bodies for increased specificity requirements in the nutrition policies of service providers.

Co-occurring self-harm and aggression (dual harm) is particularly prevalent among forensic mental health service (FMHS) patients. There is limited understanding of why this population engages in dual harm.

This work aims to explore FMHS patients’ experiences of dual harm and how they make sense of this behaviour, with a focus on the role of emotions.

Participants were identified from their participation in a previous study. Sixteen FMHS patients with a lifetime history of dual harm were recruited from two hospitals. Individuals participated in one-to-one, semi-structured interviews where they reflected on past and/or current self-harm and aggression. Interview transcripts were analysed using reflexive thematic analysis.

Six themes were generated: self-harm and aggression as emotional regulation strategies, the consequences of witnessing harmful behaviours, relationships with others and the self, trapped within the criminal justice system, the convergence and divergence of self-harm and aggression, and moving forward as an FMHS patient. Themes highlighted shared risk factors of dual harm across participants, including emotional dysregulation, perceived lack of social support and witnessing harmful behaviours. Participants underlined the duality of their self-harm and aggression, primarily utilising both to regulate negative emotions. These behaviours also fulfilled distinct purposes at times (e.g. self-harm as punishment, aggression as defence). The impact of contextual factors within FMHSs, including restrictive practices and institutionalisation, were emphasised.

Findings provide recommendations that can help address dual harm within forensic settings, including (a) transdiagnostic, individualised approaches that consider the duality of self-harm and aggression; and (b) cultural and organisational focus on recovery-centred practice.

Incarceration is a significant social determinant of health, contributing to high morbidity, mortality, and racialized health inequities. However, incarceration status is largely invisible to health services research due to inadequate clinical electronic health record (EHR) capture. This study aims to develop, train, and validate natural language processing (NLP) techniques to more effectively identify incarceration status in the EHR.

The study population consisted of adult patients (≥ 18 y.o.) who presented to the emergency department between June 2013 and August 2021. The EHR database was filtered for notes for specific incarceration-related terms, and then a random selection of 1,000 notes was annotated for incarceration and further stratified into specific statuses of prior history, recent, and current incarceration. For NLP model development, 80% of the notes were used to train the Longformer-based and RoBERTa algorithms. The remaining 20% of the notes underwent analysis with GPT-4.

There were 849 unique patients across 989 visits in the 1000 annotated notes. Manual annotation revealed that 559 of 1000 notes (55.9%) contained evidence of incarceration history. ICD-10 code (sensitivity: 4.8%, specificity: 99.1%, F1-score: 0.09) demonstrated inferior performance to RoBERTa NLP (sensitivity: 78.6%, specificity: 73.3%, F1-score: 0.79), Longformer NLP (sensitivity: 94.6%, specificity: 87.5%, F1-score: 0.93), and GPT-4 (sensitivity: 100%, specificity: 61.1%, F1-score: 0.86).

Our advanced NLP models demonstrate a high degree of accuracy in identifying incarceration status from clinical notes. Further research is needed to explore their scaled implementation in population health initiatives and assess their potential to mitigate health disparities through tailored system interventions.

New Delhi metallo-β-lactamases (NDMs) are major contributors to the spread of carbapenem resistance globally. In Australia, NDMs were previously associated with international travel, but from 2019 we noted increasing incidence of NDM-positive clinical isolates. We investigated the clinical and genomic epidemiology of NDM carriage at a tertiary-care Australian hospital from 2016 to 2021.

We identified 49 patients with 84 NDM-carrying isolates in an institutional database, and we collected clinical data from electronic medical record. Short- and long-read whole genome sequencing was performed on all isolates. Completed genome assemblies were used to assess the genetic setting of blaNDM genes and to compare NDM plasmids.

Of 49 patients, 38 (78%) were identified in 2019–2021 and only 11 (29%) of 38 reported prior travel, compared with 9 (82%) of 11 in 2016–2018 (P = .037). In patients with NDM infection, the crude 7-day mortality rate was 0% and the 30-day mortality rate was 14% (2 of 14 patients). NDMs were noted in 41 bacterial strains (ie, species and sequence type combinations). Across 13 plasmid groups, 4 NDM variants were detected: blaNDM-1, blaNDM-4, blaNDM-5, and blaNDM-7. We noted a change from a diverse NDM plasmid repertoire in 2016–2018 to the emergence of conserved blaNDM-1 IncN and blaNDM-7 IncX3 epidemic plasmids, with interstrain spread in 2019–2021. These plasmids were noted in 19 (50%) of 38 patients and 35 (51%) of 68 genomes in 2019–2021.

Increased NDM case numbers were due to local circulation of 2 epidemic plasmids with extensive interstrain transfer. Our findings underscore the challenges of outbreak detection when horizontal transmission of plasmids is the primary mode of spread.

This study assessed the work-related resources and demands experienced by children’s hospice staff to help identify staff support systems and organizational practices that offer the most potential to prevent staff burnout and enhance well-being at work.

The relationships between individual and organizational characteristics, work-related resources and demands, and burnout and work engagement outcomes experienced by children’s hospice staff were explored using two surveys: the Children’s Hospice Staff survey, completed by UK children’s hospice staff, and the Children’s Hospice Organisation and Management survey, completed by the Heads of Care. We used structural equation modeling to assess the relationships between the variables derived from the survey measures and to test a model underpinned by the Job Demands-Resource (JD-R) theory.

There were 583 staff responses from 32 hospices, and 414 participants provided valid data for burnout and work engagement outcome measures. Most participants were females (95.4%), aged 51–65 years old (31.3%), and had more than 15 years of experience in life-limiting conditions (29.7%). The average score for burnout was 32.5 (SD: 13.1), and the average score for work engagement was 7.5 (SD: 1.5). The structural model validity showed good fit. Demands significantly predicted burnout (b = 4.65, p ≤ 0.001), and resources predicted work engagement (b = 3.09, p ≤ 0.001). The interaction between resources and demands only predicted work engagement (b = −0.31, p = 0.115). Burnout did not predict work engagement (b = −0.09, p = 0.194).

The results partly supported the JD-R model, with a clear association between resources and work engagement, even when the demands were considered. Demands were only directly associated with burnout. The findings also identified a set of the most relevant aspects related to resources and demands, which can be used to assess and improve staff psychological well-being in children’s hospices in the UK.

This presentation describes an initiative to provide psychosocial support to children in Ukraine during the ongoing war using a children’s storybook, coloring book, and activity book. The resources promote emotion identification, self-expression, coping skills, and social support–variables with empirical support in promoting children’s mental health in response to trauma.

The book: “An Unusual Situation” is a bibliotherapy intervention for children struggling with difficult situations. By identifying with the characters, children learn about their own struggles, they learn that other children share similar concerns, and learn important coping skills.

The book was translated into Ukrainian and Russian; supplementary materials including a coloring book, activity book and a guidebook were developed. Following a three-hour training, Ukrainian mental health professionals worked with children on the materials in their respective wartime settings.

Results of the following research questions will be presented:

1. 1) How do mental health professionals working with children in Ukraine utilize the associated book resources measured by a survey and completed by the professionals engaged in the project.

2. 2) What do children who use these resources report about their experiences coping with the ongoing war, measured by:

   1. a) Collecting children’s responses in the activity book.

   2. b) Surveying the mental health professionals about their observations of the children during the intervention process.

3. 3) Does the intervention reduce children’s distress, interpersonal functioning, or problematic behaviors, measured by pre-post scores on the Youth Outcome Questionnaire 2.0.

This pilot study will provide information to guide the implementation of a broad psychosocial support intervention for children living in the setting of the ongoing war in Ukraine. Conclusions to be presented include:

1. 1) Tailoring the intervention to the current needs of Ukrainian children

2. 2) Designing a wide-scale implementation plan tailored to Ukrainian mental health professionals’ recommendations

3. 3) Addressing barriers to implementation.
