Autism-related dietary preferences mediate autism-gut microbiome associations.

There is increasing interest in the potential contribution of the gut microbiome to autism spectrum disorder (ASD). However, previous studies have been underpowered and have not been designed to address potential confounding factors in a comprehensive way. We performed a large autism stool metagenomics study (n = 247) based on participants from the Australian Autism Biobank and the Queensland Twin Adolescent Brain project. We found negligible direct associations between ASD diagnosis and the gut microbiome. Instead, our data support a model whereby ASD-related restricted interests are associated with less-diverse diet, and in turn reduced microbial taxonomic diversity and looser stool consistency. In contrast to ASD diagnosis, our dataset was well powered to detect microbiome associations with traits such as age, dietary intake, and stool consistency. Overall, microbiome differences in ASD may reflect dietary preferences that relate to diagnostic features, and we caution against claims that the microbiome has a driving role in ASD.

Sociodemographic and clinical indicators of children and young people with cerebral palsy and reported unmet social needs.

AIM: To determine the frequency, type, clinical, and sociodemographic associations of unmet social needs in children with cerebral palsy (CP). METHOD: We conducted a cross-sectional study of parents and carers of children with CP attending a specialist hospital clinic between July and September 2022. Unmet social needs were self-identified using a survey, guided by the WE CARE survey instrument and adapted to the local context. Sociodemographic and clinical data were obtained from medical records. We performed descriptive analysis of participants' unmet social needs, sociodemographic factors, and clinical factors, and examined for associations using a χ2 test and logistic regression. RESULTS: A total of 105 parents and carers completed the survey. Of these, 68 (64.8%) reported one or more unmet social need, with 24 (22.9%) reporting three or more unmet needs. A higher number (three or more) of unmet needs was associated with Gross Motor Function Classification System levels IV and V (odds ratio [OR] = 3.77, 95% confidence interval [CI] = 1.44-9.86) and intellectual disability (OR = 4.63, 95% CI = 1.61-13.31), but were not significant when corrected for neighbourhood socioeconomic disadvantage. The greatest socioeconomic disadvantage was associated with housing concerns (p = 0.002), food (p = 0.026), and financial insecurity (p = 0.02). INTERPRETATION: Unmet social needs are experienced by most families of children with CP. This study highlights the importance of systematic pathways to identify and address unmet social needs.

Integrated care models for youth mental health: A systematic review and meta-analysis.

OBJECTIVES: To evaluate the effectiveness of integrated models of mental healthcare in enhancing clinical outcomes, quality of life, satisfaction with care and health service delivery outcomes in young people aged 12-25 years. A secondary objective was to identify common components of integrated mental health interventions. METHODS: A systematic review and meta-analysis of studies published 2001-2023 that assessed clinical or health service use outcomes of integrated care, relative to treatment as usual, for any mental health condition in 12-25 years old accessing community-based care. RESULTS: Of 11,444 titles identified, 15 studies met inclusion criteria and 6 studies were entered in the meta-analysis. Pooled effect size found integrated care was associated with a greater reduction in depressive symptoms relative to treatment as usual at 4-6 months (standardised mean difference = -0.260, 95% confidence interval = [-0.39, -0.13], p = 0.001). Of the seven studies reporting access or engagement, all reported higher rates of both in the intervention arm. The most frequent components of integration were use of a multidisciplinary team (13/15 studies), shared treatment planning (11/15) and workforce training in the model (14/15). CONCLUSIONS: Integrated models of mental healthcare are associated with a small, but significant, increase in effectiveness for depressive symptoms relative to treatment as usual. Given integrated care may increase access and engagement, future research should focus on assessing the impact of integrated care in a wider range of settings and outcomes, including clinical and functional recovery, satisfaction with care and system-level outcomes such as cost-effectiveness.

Moving from idea to reality: The barriers and enablers to implementing Child and Family Hubs policy into practice in NSW, Australia.

BACKGROUND: Adverse childhood experiences can impact physical and mental health throughout the lifespan. To support families experiencing adversity and improve child health and developmental equity, an integrated, multi-sector response is required. Child and Family Hubs (Hubs) are a feasible and acceptable approach to providing such a response. In the Australian context, a number of federal and New South Wales (NSW) state policies support an integrated, multi-sector response using Hubs to support families experiencing adversity. This study examined NSW policy stakeholder and health service manager perspectives on the barriers and enablers to translating policy into practice in the implementation of Child and Family Hubs. METHODS: Semi-structured interviews were conducted with 11 NSW government policy stakeholders and 13 community health service managers working in child and family policy and planning or child and family community-based services. Interviews were of 30-60 min duration and explored stakeholder knowledge, perspectives and experiences around childhood adversity, and barriers and enablers to operationalizing policies supporting Hubs. Analysis of barriers and facilitators to implementation of Hub models of care was undertaken using the Consolidated Framework for Implementation Research (CFIR). RESULTS: Key barriers that emerged included short-term and inconsistent funding, lack of resourcing for a Hub co-ordinator, limited support for evaluation and insufficient time to plan for Hub implementation. Key enablers included flexibility and adaptability of Hub models to meet local needs, formal change management processes, strong governance structures and engagement among Hub practitioners. Key insights included the importance of targeted strategies to support sustained individual practice change and the need for organization-wide commitment to enable the successful adoption and maintenance of the Hub model of care. CONCLUSIONS: This study provides valuable insights and contributes evidence around what is needed to strengthen and support the operationalization and scalability of the Hub model of care. Key recommendations for Hub practitioners include the importance of formal change management processes and establishment of strong governance structures, while key recommendations for policymakers include the need for sustainable Hub funding and a standardized, evidence-based framework to support Hub implementation and evaluation.

Implementing a National Navigation Service for Perinatal and Infant Mental Health: Early Learnings from the ForWhen Model.

ForWhen is an Australia-based national navigation service aimed at helping parents and carers navigate the perinatal mental health service landscape and connect them with appropriate support and clinical services. The current study forms part of a mixed-methods evaluation of the ForWhen program. Semi-structured interviews were conducted with ForWhen navigators during the early design and implementation phases of the service. Results were used to characterise the ForWhen navigator activities and responsibilities, identify navigator core competencies, and examine facilitators and barriers to successful implementation of a large-scale navigation program for perinatal and infant mental health. Further research will be crucial for evidencing the utility and potential of navigation models in addressing identified issues with access to treatment for perinatal and infant mental health issues.

Immp2l Enhances the Structure and Function of Mitochondrial Gpd2 Dehydrogenase.

'Inner mitochondrial membrane peptidase 2 like' (IMMP2L) is a nuclear-encoded mitochondrial peptidase that has been conserved through evolutionary history, as has its target enzyme, 'mitochondrial glycerol phosphate dehydrogenase 2' (GPD2). IMMP2L is known to cleave the mitochondrial transit peptide from GPD2 and another nuclear-encoded mitochondrial respiratory-related protein, cytochrome C1 (CYC1). However, it is not known whether IMMP2L peptidase activates or alters the activity or respiratory-related functions of GPD2 or CYC1. Previous investigations found compelling evidence of behavioural change in the Immp2lKD-/- KO mouse, and in this study, EchoMRI analysis found that the organs of the Immp2lKD-/- KO mouse were smaller and that the KO mouse had significantly less lean mass and overall body weight compared with wildtype littermates (p < 0.05). Moreover, all organs analysed from the Immp2lKD-/- KO had lower relative levels of mitochondrial reactive oxygen species (mitoROS). The kidneys of the Immp2lKD-/- KO mouse displayed the greatest decrease in mitoROS levels that were over 50% less compared with wildtype litter mates. Mitochondrial respiration was also lowest in the kidney of the Immp2lKD-/- KO mouse compared with other tissues when using succinate as the respiratory substrate, whereas respiration was similar to the wildtype when glutamate was used as the substrate. When glycerol-3-phosphate (G3P) was used as the substrate for Gpd2, we observed ~20% and ~7% respective decreases in respiration in female and male Immp2lKD-/- KO mice over time. Together, these findings indicate that the respiratory-related functions of mGpd2 and Cyc1 have been compromised to different degrees in different tissues and genders of the Immp2lKD-/- KO mouse. Structural analyses using AlphaFold2-Multimer further predicted that the interaction between Cyc1 and mitochondrial-encoded cytochrome b (Cyb) in Complex III had been altered, as had the homodimeric structure of the mGpd2 enzyme within the inner mitochondrial membrane of the Immp2lKD-/- KO mouse. mGpd2 functions as an integral component of the glycerol phosphate shuttle (GPS), which positively regulates both mitochondrial respiration and glycolysis. Interestingly, we found that nonmitochondrial respiration (NMR) was also dramatically lowered in the Immp2lKD-/- KO mouse. Primary mouse embryonic fibroblast (MEF) cell lines derived from the Immp2lKD-/- KO mouse displayed a ~27% decrease in total respiration, comprising a ~50% decrease in NMR and a ~12% decrease in total mitochondrial respiration, where the latter was consistent with the cumulative decreases in substrate-specific mediated mitochondrial respiration reported here. This study is the first to report the role of Immp2l in enhancing Gpd2 structure and function, mitochondrial respiration, nonmitochondrial respiration, organ size and homeostasis.

Editorial: Equity, diversity and inclusion in child and adolescent mental health - equality of opportunities should be every child's right and every society's obligation.

Socio-ecological factors are major determinants of poor mental health across the life span. These factors can lead to health inequalities, which refer to differences in the health of individuals or groups (Kirkbride et al., 2024). Health inequity "is a specific type of health inequality that denotes an unjust, avoidable, systematic and unnecessary difference in health" (Arcaya, Arcaya, & Subramanian, 2015). Among several intersecting social adversities, inequity is one of the most pervasive contributors to poor mental health across all regions (Venkatapuram & Marmot, 2023). Structural inequity creates institutional power structures that marginalise large sections of the population and concentrate resources in the hands of a small minority (Shim, Kho, & Murray-García, 2018). The world is now more prosperous than it has ever been, yet the world is witnessing more within country inequality with the vast majority of the world's resources in the hands of a small minority of individuals or regions (United Nations, 2020).

Combining CBT and sertraline does not enhance outcomes for anxious youth: a double-blind randomised controlled trial.

BACKGROUND: Anxiety disorders are the most prevalent mental disorder in children and young people. Developing effective therapy for these children is critical to reduce mental disorders across the lifespan. The study aimed to evaluate the efficacy of combining cognitive behavioural therapy (CBT) and sertraline (SERT) in the treatment of anxiety in youth, using a double-blind randomised control trial design. METHODS: Ninety-nine youth (ages 7-15 years) with an anxiety disorder were randomly allocated to either individual (CBT) and SERT or individual CBT and pill placebo and assessed again immediately and 6 months after treatment. RESULTS: There were no significant differences between conditions in remission of primary anxiety disorder or all anxiety disorders. Furthermore, there were no significant differences in rates of change in diagnostic severity, parent-reported anxiety symptoms, child-reported anxiety symptoms or life interference due to anxiety. CONCLUSIONS: The efficacy of CBT for children and adolescents with anxiety disorders is not significantly enhanced by combination with a short-term course of anti-depressants over and above the combined effects of pill placebo.

Facial reactions to emotional films in young children with conduct problems and varying levels of callous-unemotional traits.

BACKGROUND: Elevated levels of callous-unemotional (CU) traits have proven useful for identifying a distinct subgroup of children whose conduct problems (CP) are early emerging, severe, persistent, and underpinned by aberrant emotional processing. The early childhood emotional experiences and expressions of CP subtypes are poorly understood, despite their importance to understanding the problematic attachments and atypical social affiliation experienced by children with elevated CU traits. The current study aimed to test for differences in facial emotional reactions to mood-inducing film clips in children with CP and varying levels of CU traits. METHOD: We compared facial emotional reactions during a developmentally appropriate mood induction task in a mixed-sex sample of clinic-referred preschool children (Mage = 3.64 years, SD = 0.63, 66.9% male) classified as CP with elevated levels of CU traits (CP + CU; n = 25) versus low CU traits (CP-only; n = 47), and typically developing children (TD; n = 28). RESULTS: Relative to TD children, children with clinical CP showed less congruent and more incongruent facial emotional expressions to sad and happy film clips, controlling for child sex, age, and ethnicity. CONCLUSIONS: Consistent with older samples, young children with CP show atypical facial emotional expressions in response to positive and negative emotional stimuli. Findings have implications for developmental models of childhood antisocial behavior and can inform the development of targeted interventions.

Eye-tracking correlates of response to joint attention in preschool children with autism spectrum disorder.

BACKGROUND: A number of differences in joint attention behaviour between children with autism spectrum disorder (ASD) and typically developing (TD) individuals have previously been documented. METHOD: We use eye-tracking technology to assess response to joint attention (RJA) behaviours in 77 children aged 31 to 73 months. We conducted a repeated-measures analysis of variance to identify differences between groups. In addition, we analysed correlations between eye-tracking and clinical measures using Spearman's correlation. RESULTS: The children diagnosed with ASD were less likely to follow gaze compared to TD children. Children with ASD were less accurate at gaze following when only eye gaze information was available, compared to when eye gaze with head movement was observed. Higher accuracy gaze-following profiles were associated with better early cognition and more adaptive behaviours in children with ASD. Less accurate gaze-following profiles were associated with more severe ASD symptomatology. CONCLUSION: There are differences in RJA behaviours between ASD and TD preschool children. Several eye-tracking measures of RJA behaviours in preschool children were found to be associated with clinical measures for ASD diagnosis. This study also highlights the construct validity of using eye-tracking measures as potential biomarkers in the assessment and diagnosis of ASD in preschool children.

A mixed-methods evaluation of a state-wide outreach perinatal mental health service.

BACKGROUND: Access to perinatal mental health services in rural and remote areas is scarce, particularly perinatal psychiatry services. Telehealth, together with psychiatry consultation-liaison services are one way to improve access to areas of need. The New South Wales State-wide Outreach Perinatal Services - Mental Health (SwOPS) program is a Sydney-based program, offering specialist perinatal consultation-liaison services to rural and remote community mental health clinicians caring for perinatal women with significant mental health problems. This study aimed to evaluate healthcare practitioners' perceptions of the SwOPS program. METHOD: Healthcare practitioners (N = 31) were purposely recruited to participate in the study. Data were analysed using a mixed-methods cross-sectional design. RESULTS: Most participants reported being familiar with and satisfied with the service. As a result of accessing the service, participants reported an increase in knowledge and confidence regarding caring for women with moderate-to-severe or complex mental health conditions. Qualitative comments highlight the participant's perceptions of the program. CONCLUSION: This study provides useful insights about a state-wide telehealth psychiatry consultation-liaison service from the perspective of practitioners. It highlights the benefits, facilitators, and barriers associated with implementing such services.

Sympathetic nervous system functioning during the face-to-face still-face paradigm in the first year of life.

Contemporary theories of early development and emerging child psychopathology all posit a major, if not central role for physiological responsiveness. To understand infants' potential risk for emergent psychopathology, consideration is needed to both autonomic reactivity and environmental contexts (e.g., parent-child interactions). The current study maps infants' arousal during the face-to-face still-face paradigm using skin conductance (n = 255 ethnically-diverse mother-infant dyads; 52.5% girls, mean infant age = 7.4 months; SD = 0.9 months). A novel statistical approach was designed to model the potential build-up of nonlinear counter electromotive force over the course of the task. Results showed a significant increase in infants' skin conductance between the Baseline Free-play and the Still-Face phase, and a significant decrease in skin conductance during the Reunion Play when compared to the Still-Face phase. Skin conductance during the Reunion Play phase remained significantly higher than during the Baseline Play phase; indicating that infants had not fully recovered from the mild social stressor. These results further our understanding of infant arousal during dyadic interactions, and the role of caregivers in the development of emotion regulation during infancy.

Stemming the tide of mental health problems in young people: Challenges and potential solutions.

One in five people experience clinically relevant mental health problems before the age of 25 years. Furthermore, in Australia, one in seven children are reported to experience a mental health disorder. Consequently, there has been a steady increase in demand for mental health services for children and young people, and this has been compounded by the COVID-19 pandemic. Unfortunately, currently many children and young people with mental health difficulties are not accessing appropriate and/or timely care, with individuals and families finding it increasingly difficult to access and navigate suitable services. In part, this is related to the fragmented and isolated manner in which child mental health services are operating. To address the current issues in access to appropriate child and adolescent mental health care in Australia, a novel Integrated Continuum of Connect and Care model is proposed to integrate relevant services along a tiered care pathway. The aim of this model is to facilitate timely access to mental health services that meet the specific needs of each child/young person and their family. This model will function within co-located service hubs that integrate health care through a comprehensive assessment followed by a link up to relevant services. The Integrated Continuum of Connect and Care has the potential to pave the way for unifying the fragmented child and youth mental health system in Australia.

The Australian evidence-based clinical practice guideline for attention deficit hyperactivity disorder.

OBJECTIVE: The objective of this article was to provide an overview of the development and recommendations from the Australian evidence-based clinical practice guideline for attention deficit hyperactivity disorder (ADHD). The guideline aims to promote accurate and timely identification and diagnosis, and optimal and consistent treatment of ADHD. METHODS: Development integrated the best available evidence with multidisciplinary clinical expertise and the preferences of those with lived experience, underpinned by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. The 23 guideline development group members included psychiatrists, paediatricians, general practitioners, psychologists, speech pathologists, occupational therapists, educators, Indigenous psychologists, and people with a lived experience; with two independent chairs and a methodologist. Where appropriate, evidence reviews from the National Institute for Health and Care Excellence (NICE) 2018 'Attention Deficit Hyperactivity Disorder: Diagnosis and Management' guideline were updated. Fifty prioritised clinical questions were addressed in 14 systematic reviews (new and updated from NICE 2018) and 28 narrative reviews. RESULTS: The 113 clinical recommendations apply to young children (5 years and under), children, adolescents and adults. They provide guidance for clinicians on identification, screening, diagnosis, multimodal treatment and support, including pharmacological and non-pharmacological interventions. The guideline and supporting information are available online: https://adhdguideline.aadpa.com.au/. CONCLUSIONS: The guideline was approved by the National Health and Medical Research Council (NHMRC) of Australia and relevant medical and allied health professional associations. It is anticipated that successful implementation and uptake of the guideline by organisations, health care providers and other professionals will increase delivery of evidence-based treatment and improve health outcomes for the more than 800,000 Australians with ADHD.

Sociocultural factors associated with detection of autism among culturally and linguistically diverse communities in Australia.

BACKGROUND: The age at which parents or caregivers first develop concerns about their child's development has significant implications on formal diagnosis and intervention. This study aims to determine the sociocultural factors that are associated with the age and type of first concern reported by parents of autistic children among culturally and linguistically diverse (CALD) communities in Australia. We also assessed whether sociocultural factors predict autism traits measured in terms of social affect (SA), restricted and repetitive behaviours (RRB), and calibrated severity scores (CSS). METHODS: This study is a secondary data analysis of the data collected from six Autism Specific Early Learning and Care Centres (ASELCCs) as part of the Autism Co-operative Research Centre (CRC) program between 2015 and 2019. Data analysed in this study included a family history questionnaire with sociodemographic and sociocultural information, parent-reported age and type of first concern, and clinician/researcher administered Autism Diagnostic Observation Schedule - Second Edition (ADOS-2) which includes standardised domain-wise scores of social affect (SA) and restricted and repetitive behaviours (RRB) as well as calibrated severity scores (CSS), a measure of severity of autism. Primary analysis included multivariable linear regression models to examine the predictive influence of sociodemographic and sociocultural factors on the dependant variables of age of concern (AOC) and the autism traits (SA, RRB, and CSS). RESULTS: The mean AOC in the sample was 18.18 months and the most common concerns were speech/language delay, limited social interaction, and hyperactivity/behavioural changes. The multivariable linear regression models showed factors such as increase in age of child, those from a CALD background, annual family income, sibling's autism diagnosis, and developmental concerns to be significantly associated with parental AOC. Additionally, we also found that increase in child's age and CALD status to be significant predictors of autism trait (RRB) and severity measured in terms of the CSS score. Further, females (compared to males) were associated with higher difficulties with social communication and interaction skills. CONCLUSION: Understanding key factors that contribute to early identification of autism can help tailor awareness programs for parents and caregivers, whilst also informing the development of services focused on serving all CALD communities.

Parenting Characteristics and Callous-Unemotional Traits in Children Aged 0-6 Years: A Systematic Narrative Review.

There has been a growing interest in research examining the relationship between parenting and child callous-unemotional (CU) traits, particularly in early childhood. This study reviewed evidence from studies that investigated the relationship between parenting characteristics (e.g., caregiving beliefs, attitudes, behaviour or quality, or parental mental health) and callous-unemotional traits in children aged 0 to 6 years. A systematic search conducted according to PRISMA guidelines yielded 27 peer-reviewed articles. Analysis of the included articles suggested that there was strong evidence to support links between child CU traits and parenting characteristics (particularly, parental feelings about their child, warm parenting, and harsh/ inconsistent parenting). Taken together, the results of this review demonstrate the links between both positive and negative dimensions of parenting and CU traits in early childhood; however, mixed findings highlight the need for further research.

Preschool Behavioral Problems: Links with Maternal Oxytocin and Caregiving Sensitivity in the Postnatal Period, and Concurrent Maternal Psychopathology and Attachment State-of-Mind.

This study investigated maternal oxytocin, caregiving sensitivity and mother-to-infant bonding at 3-months postpartum as predictors of child behavior and psychological outcomes in the preschool years, when controlling for concurrent maternal negative emotional symptoms and adult attachment state-of-mind. Forty-five mother-child dyads were assessed at 3-months and 3.5 years postpartum using mix of questionnaires, observational, interview and biological methods. Results showed that lower levels of maternal baseline oxytocin at 3-months postpartum significantly predicted emotional reactivity in the child at 3.5 years. When maternal adult attachment state-of-mind and negative emotional symptoms were included, lower levels of maternal baseline oxytocin at 3-months postpartum significantly predicted withdrawn child behavior. In addition, unresolved adult attachment and maternal negative emotional symptoms were significantly associated child behavioral disturbance in a range of areas. Findings highlight maternal postnatal oxytocin as a potential indicator of children who may be more likely to show emotional reactivity and withdrawn behavior in the preschool years.

Towards Preventative Psychiatry: Concurrent and Longitudinal Predictors of Postnatal Maternal-Infant Bonding.

Maternal-infant bonding is important for children's positive development. Poor maternal-infant bonding is a risk factor for negative mother and infant outcomes. Although researchers have examined individual predictors of maternal-infant bonding, studies typically do not examine several concurrent and longitudinal predictors within the same model. This study aimed to evaluate the unique and combined predictive power of cross-sectional and longitudinal predictors of maternal-infant bonding. Participants were 372 pregnant women recruited from an Australian hospital. Data were collected from mothers at antenatal appointments (T0), following their child's birth (T1), and at a laboratory assessment when their child was 5-11-months-old (T2). Poorer bonding at T2 was predicted at T0 by younger maternal age, higher education, and higher antenatal depressive symptoms. Poorer bonding at T2 was predicted at T1 by younger maternal age, higher education, and higher postnatal depressive symptoms. Poorer bonding at T2 was predicted at T2 by younger maternal age, higher education, higher postnatal depression symptoms, higher concurrent perceived social support, and more difficult infant temperament, when controlling for child age at T2. To promote positive maternal-infant bonding, global and targeted interventions in the perinatal period may benefit from targeting maternal psychopathology, perceived lack of social support, and coping with difficult infant temperament.

Critical success factors for school-based integrated health care models: Learnings from an Australian example.

ISSUES ADDRESSED: Integrated school-based health services have the potential to address the unmet health needs of children experiencing disadvantage, yet these models remain poorly evaluated. The current article examines an integrated social and health care hub located on the grounds of a regional Australian public primary school, the Our Mia Mia Wellbeing Hub, to identify critical success factors for this service and others like it. METHODS: Semi-structured qualitative interviews were conducted with N = 55 multi-sector stakeholders comprising parents, students, school staff, social and health care providers, and local Aboriginal community members. Interview transcripts were analysed according to a grounded theory approach. RESULTS: Six themes emerged from the analysis, reflecting important success factors for the model: service accessibility; service coordination; integration of education and health systems; trust; community partnerships; and perceptions of health. CONCLUSIONS: Findings highlighted Our Mia Mia as a promising model of care, yet also revealed important challenges for the service as it responds to the varied priorities of the stakeholders it serves. SO WHAT?: Through capturing the perspectives of a large number of stakeholders, the current study provides valuable insight into key challenges and success factors for Our Mia Mia; these learnings can guide the development of other emerging school-based health services and integrated care hubs.
