Pulmonary atresia with intact ventricular septum is a rare congenital cardiac lesion with significant anatomical heterogeneity. Surgical planning of borderline cases remains challenging and is primarily based on echocardiography. The aim was to identify echocardiographic parameters that correlate with surgical outcome and to develop a discriminatory calculator.
Methods:
Retrospective review of all pulmonary atresia with intact ventricular septum cases at a statewide tertiary paediatric cardiac centre was performed between 2004 and 2020. Demographic, clinical, and echocardiographic data were collected. Logistic regression was used to develop a discriminatory tool for prediction of biventricular repair.
Results:
Forty patients were included. Overall mortality was 27.5% (n = 11) and confined to patients managed as univentricular (11 vs 0, p = 0.027). Patients who underwent univentricular palliation were more likely to have an associated coronary artery abnormality (17 vs 3, p = 0.001). Fifteen surviving patients (51.7%) achieved biventricular circulation while 14 (48.3%) required one-and-a-half or univentricular palliation. Nineteen patients (47.5%) underwent percutaneous pulmonary valve perforation. No patients without tricuspid regurgitation achieved biventricular repair. The combination of tricuspid valve/mitral valve annulus dimension ratio and right ventricle/left ventricle length ratio identified biventricular management with a sensitivity of 93% and specificity of 96%. An online calculator has been made available.
Conclusion:
Pulmonary atresia with intact ventricular septum is a challenging condition with significant early and interstage morbidity and mortality risk. Patient outcomes were comparable to internationally reported data. Right ventricle/left ventricle length and tricuspid valve/mitral valve annulus dimension ratios identified a biventricular pathway with a high level of sensitivity and specificity. Absent tricuspid regurgitation was associated with a univentricular outcome.
Cognitive therapy for PTSD (CT-PTSD) is an efficacious treatment for children and adolescents with post-traumatic stress disorder (PTSD) following single incident trauma, but there is a lack of evidence relating to this approach for youth with PTSD following exposure to multiple traumatic experiences.
Aims:
To assess the safety, acceptability and feasibility of CT-PTSD for youth following multiple trauma, and obtain a preliminary estimate of its pre–post effect size.
Method:
Nine children and adolescents (aged 8–17 years) with multiple-trauma PTSD were recruited to a case series of CT-PTSD. Participants completed a structured interview and mental health questionnaires at baseline, post-treatment and 6-month follow-up, and measures of treatment credibility, therapeutic alliance, and mechanisms proposed to underpin treatment response. A developmentally adjusted algorithm for diagnosing PTSD was used.
Results:
No safety concerns or adverse effects were recorded. Suicidal ideation reduced following treatment. No participants withdrew from treatment or from the study. CT-PTSD was rated as highly credible. Participants reported strong working alliances with their therapists. Data completion was good at post-treatment (n=8), but modest at 6-month follow-up (n=6). Only two participants met criteria for PTSD (developmentally adjusted algorithm) at post-treatment. A large within-subjects treatment effect was observed post-treatment and at follow up for PTSD severity (using self-report questionnaire measures; ds>1.65) and general functioning (CGAS; ds<1.23). Participants showed reduced anxiety and depression symptoms at post-treatment and follow-up (RCADS-C; ds>.57).
Conclusions:
These findings suggest that CT-PTSD is a safe, acceptable and feasible treatment for children with multiple-trauma PTSD, which warrants further evaluation.
The identification of predictors of treatment response is crucial for improving treatment outcome for children with anxiety disorders. Machine learning methods provide opportunities to identify combinations of factors that contribute to risk prediction models.
Methods
A machine learning approach was applied to predict anxiety disorder remission in a large sample of 2114 anxious youth (5–18 years). Potential predictors included demographic, clinical, parental, and treatment variables with data obtained pre-treatment, post-treatment, and at least one follow-up.
Results
All machine learning models performed similarly for remission outcomes, with AUC between 0.67 and 0.69. There was significant alignment between the factors that contributed to the models predicting two target outcomes: remission of all anxiety disorders and the primary anxiety disorder. Children who were older, had multiple anxiety disorders, comorbid depression, comorbid externalising disorders, received group treatment and therapy delivered by a more experienced therapist, and who had a parent with higher anxiety and depression symptoms, were more likely than other children to still meet criteria for anxiety disorders at the completion of therapy. In both models, the absence of a social anxiety disorder and being treated by a therapist with less experience contributed to the model predicting a higher likelihood of remission.
Conclusions
These findings underscore the utility of prediction models that may indicate which children are more likely to remit or are more at risk of non-remission following CBT for childhood anxiety.
Product architecture decisions are made early in the product development process and have far-reaching effects. Unless anticipated through experience or intuition, many of these effects may not be apparent until much later in the development process, making changes to the architecture costly in time, effort and resources. Many researchers through the years have studied various elements of product architecture and their effects. By using a repeatable process for aggregating statements on the effects of architecture strategies from a selection of the literature on the topic and storing them in a systematic database, this information can then be recalled and presented in the form of a Product Architecture Strategy and Effect (PASE) matrix. PASE matrices allow for the identification, comparison, evaluation, and then selection of the most desirable product architecture strategies before expending resources along a specific development path. This paper introduces the PASE Database and matrix and describes their construction and use in guiding design decisions. This paper also provides metrics for understanding the robustness of this database.
We evaluated the feasibility and acceptability of frailty screening using handgrip strength with gait speed measures within four primary care-based memory clinics in Ontario. This mixed methods quality improvement initiative examined the reach, effectiveness, adoption, implementation, and maintenance of frailty screening from the perspective of patients (N = 216), care partners (N = 142), and healthcare providers (N = 9). Frailty screening was well-received by patients and care partners and perceived as quick and easy to administer and integrate into assessment processes by healthcare providers at all four memory clinics. The ease of integrating frailty screening into clinic processes was a key factor facilitating implementation; few challenges or suggestions for improvement were identified. All four clinics plan to continue frailty screening, three using the methods adopted in this study. Integrating frailty screening into memory assessments is feasible and acceptable and, given the interactional relationship between frailty and dementia, provides a significant opportunity to improve health outcomes for older adults.
This study examined the power of theory-derived models to account for the development of PTSD, Complex PTSD (CPTSD), depression, and anxiety in children and adolescents who had experienced a single-event trauma.
Methods
Children (n = 234, aged 8–17 years) recruited from local Emergency Departments were assessed at two and nine weeks post-trauma. Data obtained from self-report questionnaires completed by the child, telephone interviews with parents, and hospital data were used to develop four predictive models of risk factors for PTSD, CPTSD, depression, and Generalized Anxiety Disorder (GAD). ICD-11 proposed diagnostic criteria were used to generate measures for CPTSD and PTSD to assess for risk factors and identify the sample prevalence of these disorders.
Results
At nine weeks post-trauma, 64% did not meet criteria for any disorder, 23.5% met criteria for PTSD, and 5.2% met criteria for CPTSD. 23.9% and 10.7% had developed clinically significant symptoms of depression and GAD, respectively. A cognitive model was the most powerful predictive model, a psychosocial model was weak, and subjective markers of event severity were more powerful than objective measures.
Conclusions
Youth exposed to single-incident trauma may develop different forms of psychopathology, and PTSD and CPTSD are frequently experienced alongside other conditions. The cognitive model of PTSD shows utility in identifying predictors of PTSD, CPTSD, depression, and GAD, particularly the role of trauma-related negative appraisals. This supports the application of cognitive interventions which focus upon re-appraising trauma-related beliefs in youth.
Over 2.7 million people have an opioid use disorder (OUD). Opioid-related deaths have steadily increased over the last decade. Although emergency department (ED)-based medication for OUD (MOUD) has been successful in initiating treatment for patients, there still is a need for improved access. This study describes the development of a prehospital MOUD program.
Methods:
An interdisciplinary team expanded a MOUD program into the prehospital setting through the local city fire department Quick Response Team (QRT) to identify patients appropriate for MOUD treatment. The QRT consisted of a paramedic, social worker, and police officer. This team visited eligible patients (i.e., history of an opioid overdose and received prehospital care the previous week). The implementation team developed a prehospital MOUD protocol and a two-hour training course for QRT personnel. Implementation also required a signed contract between local hospitals and the fire department. A drug license was necessary for the QRT vehicle to carry buprenorphine/naloxone, and a process to restock the vehicle was created. Pamphlets were created to provide to patients. A clinical algorithm was created for substance use disorder (SUD) care coordinators to provide a transition of care for patients. Metrics to evaluate the program included the number of patients seen, the number enrolled in an MOUD program, and the number of naloxone kits dispensed. Data were entered into iPads designated for the QRT and uploaded into the Research Electronic Data Capture (REDCap) program.
Results:
Over the six-month pilot, the QRT made 348 visits. Of these, the QRT successfully contacted 83 individuals, and no individuals elected to be evaluated for new MOUD treatment. Nine fatal opioid overdoses occurred during the study period. A total of 55 naloxone kits were distributed, and all patients received MOUD information pamphlets.
Conclusions:
A prehospital MOUD program can be established to expand access to early treatment and continuity of care for patients with OUD. The program was well-received by the local city fire department and QRT. There is a plan to expand the prehospital MOUD program to other local fire departments with QRTs.
Specialist forensic community teams for people with intellectual disability and/or autism have been developed, but little is known about their extent and delivery.
Aims
To describe specialist forensic community teams for people with intellectual disability and/or autism across the UK.
Method
An online survey was sent to representatives of each UK Trust/Health Board providing adult mental health and/or intellectual disability services. Questions covered the availability, structure and activities of specialist community forensic services. Quantitative data were summarised and associations between access to specialist forensic teams and care were tested with Chi-squared tests. Thematic analysis of free-text survey responses was used to understand the challenges of providing community forensic mental health services for this group.
Results
A total of 49 out of 78 (63%) eligible Trusts/Health Boards responded, of which 25 (51%) had access to a specialist forensic community team. Teams operated either as part of a single Trust/Board (n = 13) or over a larger regional footprint (n = 12). The availability of specialist forensic community teams was associated with better access to offence-related interventions (χ2 = 15.1002, P < 0.005) and co-production of patient care plans (χ2 = 7.8726, P = 0.005). Respondents reported a wide variation in availability, expertise and perceived quality of community services. The availability of secure and generic in-patient beds, commissioning and legal barriers were also significant challenges in providing appropriate care.
Conclusions
Coverage of specialist community forensic teams is not universal. There are indications that such teams are associated with improved care processes, but further work is needed to establish longer-term outcomes and the optimal model of care.
Defence Science and Technology Group (DSTG) is currently preparing for the launch of the Buccaneer Main Mission (BMM) satellite, the successor to the Buccaneer Risk Mitigation Mission (BRMM). BMM hosts a high-frequency (HF) antenna and receiver to contribute to the calibration of the Jindalee Operational Radar Network (JORN). Verification of the successful deployment and stability of the large HF antenna is critical to the success of the mission. A bespoke deployable optics payload has been developed by DSTG to fulfil the dual purpose of direct verification of the deployed state of the HF antenna and capturing images of the Earth through a rotatable, dual-surfaced mirror and a variable-focus liquid lens. The payload advances research at DSTG in several fields of space engineering, including deployable mechanisms, precision actuation devices, radiation-tolerant electronics, advanced metal polishing and optical metrology. This paper discusses the payload design, material selection, trade-offs considered for the deployable optics payload and preliminary test results.

People with a wide range of mental health and neurodevelopmental conditions are found amongst criminal justice populations, and many present with co-occurring disorders. These may include other neurodevelopmental conditions, substance use disorders or physical health conditions. It is now standard practice to use a pathways approach to organise and deliver services, and journeys taken by many people within criminal justice systems lend themselves to this, at least in theory. Basic requirements of this approach include police custody and prison reception screening, providing organised multidisciplinary care and introducing appropriate interventions as part of individual care plans. There is much we still do not know about vulnerable people in prisons, and service provision remains far from optimal. In particular, insufficient specialist provision means that many people with neurodevelopmental conditions are not identified appropriately, and do not have their needs met as they should. Further, in the absence of support, the presentations of some people render them vulnerable to specific aspects of prison life.
From the earliest period of British invasion of the lands now referred to as Australia, white authorities have removed Indigenous children from their communities. Sana Nakata even states that ‘the history of Australia is a history of interventions into the childhoods of Aboriginal and Torres Strait Islander people’. In this chapter, we describe how Indigenous child removal has been perpetrated in Australia since 1914. We consider the period from 1914 until the 1980s, during which the removal of Indigenous children was explicitly enabled under a growing range of laws and policies. While it is impossible to calculate the exact number of children removed during this period, the National Inquiry into the Separation of Aboriginal and Torres Strait Islander Children from their Families (henceforth ‘the National Inquiry’), headed by federal judge Sir Ronald Wilson, concluded in 1997 that ‘Most [Indigenous] families have been affected, in one or more generations, by the forcible removal of one or more children.’ In this chapter, we also consider the contemporary context, from the 1990s onwards, in which Australian governments have apologised for the historic Stolen Generations but continue to remove Indigenous children from their families in rising numbers.
The authors critique trauma and illness models of the effects of adversity, and go on to consider alternative societal and political understandings.They then review biological insights from attachment theory and affective neuroscience. An analogy with grief leads to consideration of post-traumatic growth, and adversity activated development.
A review of symptoms resulting from adversity then leads to consideration of the factors that help people rebuild their lives after major adversity, such as safety and security, interpersonal bonds, and networks.A positive sense of one’s identity and role, and feeling that life is just and meaningful, also helps.Effects of the asylum process often counter these factors.
People’s problems often have to be categorised as ‘health’ issues in order to access care. Positive and negative effects of this are reviewed.
People in the asylum system who might benefit from mental health care frequently find it very difficult to access this.
Some do not seek help, perhaps because they do not expect mental health services to be helpful or because of fear, stigma, or wanting to avoid the processes of help-seeking.Those who do seek help encounter multiple challenges including language barriers, the limitations of health care provision within the asylum system, difficulties negotiating primary care, NHS charges, practical difficulties in getting to a first appointment, and service eligibility criteria. People may face barriers linked to their age, gender, sexuality, or being destitute.
The chapter offers a typology of obstacles to reaching effective mental health care as a step towards considering how these may be addressed.This considers the context (resource limitations /ambivalence about providing equal care) and the sources of specific obstacles, including ‘hostile’ asylum policies. Recurring themes include the need for accessible information,friendly compassionate staff, cultural competence, access to qualified interpreters, appropriately trained staff, and a willingness to be flexible.
Indigenous people have been subject to racialised legislation and practice across all jurisdictions in Australia. This chapter characterises the fight against these as the Aboriginal civil rights movement. We trace key moments is this history, looking at the connections and movement building undertaken by different Indigenous people and organisations. Starting in 1927 with the founding of Australian Aboriginal Progressive Association (AAPA), the other significant political resistance we look at are - 1938 Day of Mourning, 1956 founding of the Australian-Aboriginal Fellowship (AAF), 1958 the Federal Council for Aboriginal Advancement (FCAA), the 1965 Freedom Rides, and the 1967 Referendum. We end by turning to the 1970s Black Power movement and the new ways Aboriginal people undertook social change battles.
The fields of media archaeology and data sonification have not been without contestation regarding means and methods. However, in combination, these fields present an opportunity for a novel approach to the creation of media archaeologically informed sound-based art. This article discusses the artistic use of data sonification techniques and the need to balance the musification of data while maintaining a sense of the underlying data. The use of data sonification techniques within media archaeology to facilitate the organisation of sound is briefly discussed. A framework is presented for utilising data sonification to facilitate the organisation of sound within the lens of media archaeology inquiry. Such an approach provides a novel method in media archaeologically informed sound-based art that utilises the sound of the artefact as a method of expression between genealogically related forms of media. A sound installation developed by the authors is presented that critically examines the use of, and gives concrete form to, the framework and the ideas established in this article.
