Exposure to trauma is common and frequently overlooked in behaviorally dysregulated youth. Common trauma-related symptoms, such as exaggerated startle responses, dissociative episodes, and irritability, may resemble behavioral dysregulation. These responses may not be recognized as being related to trauma. As a result, traumatized young people are often misdiagnosed and treated with antipsychotics. Trauma-informed care in health care settings, which includes systematic screening, staff training, trauma skills groups, and ongoing monitoring, is one way of addressing the effects of trauma and ensuring that young people receive access to the evidence-based care they deserve.

Trauma exposure in children and adolescents is a significant public health concern due to its profound impact on mental health and development. This study explores the complexities of trauma in youth, including the differentiation between trauma exposure and posttraumatic stress disorder, and the long-term effects of adverse childhood experiences. The study discusses the risks and benefits of polypharmacy in treating complex trauma and comorbid conditions in youth. Given the current gaps in research, the study emphasizes the need for comprehensive, individualized treatment plans that integrate psychotherapy, pharmacologic interventions, and psychosocial support to foster resilience and improve outcomes for trauma-exposed youth.

BACKGROUND AND OBJECTIVE/OBJECTIVE:Individuals with attention-deficit/hyperactivity disorder, their families and clinicians may report worsening symptoms despite compliant use of medication, suggesting potential tolerance, but evidence remains conflicting. Some studies have also suggested tachyphylaxis, or acute tolerance, though research is limited. We conducted the first systematic review of empirical studies focussing on tolerance/tachyphylaxis to attention-deficit/hyperactivity disorder medication to clarify their potential clinical relevance. METHODS:As registered on PROSPERO (CRD42024594759), we searched PubMed, OVID (including PsychInfo and MEDLINE) and Web of Knowledge up to 1 September, 2024, and assessed the risk of bias using National Institutes of Health quality assessment tools. RESULTS:The identified 17 studies were either interventional or observational, and varied greatly in design and duration. Four investigated tachyphylaxis, nine tolerance to the subjective and behavioural effects, and four tolerance to cardiovascular effects. We found preliminary evidence of tachyphylaxis to the affective or behavioural effects of stimulants, as well as tolerance to the subjective effects of d-amphetamine, such as drug liking and excitation, in neurotypical volunteers in the short term. Conversely, there was little or no evidence for tolerance to the therapeutic or cardiovascular effects of attention-deficit/hyperactivity disorder medication in clinical settings in the longer term. Quality was rated as low in most studies because of small sample sizes and methodological limitations. CONCLUSIONS:Overall, these results do not support the hypothesis that tolerance commonly develops to the therapeutic effects of attention-deficit/hyperactivity disorder medication, although robustly designed longitudinal studies are needed to provide more conclusive evidence. Clinicians may consider other potential explanations for reduced therapeutic effects over time, including natural fluctuations of symptoms, limited compliance, life events and co-occurrent mental health conditions.

OBJECTIVE:Childhood inhibited temperament (cIT) is associated with an increased risk for developing internalizing psychopathology. Neurobiological characteristics identified by structural magnetic resonance imaging (MRI) may elucidate the neural substrates for cIT, but studies are scarce and often focus on particular regions of interest. Moreover, current findings lack replication. This pre-registered analysis from the ENIGMA-Anxiety Working Group examined structural brain characteristics associated with cIT using a comprehensive whole-brain approach. METHOD/METHODS:Temperament assessments (behavioral observations, parental/teacher reports or self-reports on cIT before age 13) and MRI-data (age at scan: 6-25 years) from international research sites (Europe, North America, South America) were pooled for mega-analysis. Following image processing and quality control, associations between cIT and brain structure were examined in 3,803 participants. Subcortical volumes, cortical thickness and surface area (main analyses) and detailed subcortical characteristics (e.g. subnuclei, subfields, partial volume effects; exploratory analyses) were considered. RESULTS:= 0.029) in youth with parental/teacher reports on cIT-levels. Exploratory analyses revealed findings in hippocampus, putamen and caudate, but most did not survive statistical correction for multiple testing. CONCLUSION/CONCLUSIONS:This mega-analysis found no consistent associations between cIT and regional brain structure, although the role of parietal regions warrants further investigation. Future studies should consider brain function in cIT, preferably using longitudinal designs.

Currently, the identification of individuals experiencing suicidal thoughts and behaviours (STBs) rely predominantly on self-report. Previous research on children and young people highlighted an association between difficulties in arousal regulation (reflected, for example, in reduced heart rate variability and altered electrodermal activity patterns) and STBs, but this has not been meta-analytically explored in adults. This systematic review and meta-analysis aimed to quantify the association between STBs and markers of autonomic functioning/regulation in adults. Based on a pre-registered protocol (PROSPERO CRD42024596886), we searched PubMed/MEDLINE, Embase, PsycINFO and Web of Science until 2^nd August 2025 for empirical studies assessing the association between measures of autonomic functioning and/or regulation and STBs in adults. Quality of cross-sectional and cohort studies was assessed through the Newcastle-Ottawa Scale. Pooled effect sizes (Hedge's g) were estimated with random-effects meta-analytic models in R. Out of 2,726 articles screened, 40 studies were included in the systematic review, and 22 in the meta-analyses (6,290 individuals, 28% with STBs). We found reduced heart rate variability in adults with STBs (g = -0.2469, p = 0.0069) but no significant associations between electrodermal activity patterns and STBs (g = -0.2563, p = 0.3953). Our results highlight the connection between reduced cardiac regulation and STBs, providing a rationale for further exploration of cardiac regulation as a potential objective marker for assessing and monitoring STBs in adults. Further research is warranted to understand how these markers can be used in clinical practice to assess and support the management of suicide risk in adults.

OBJECTIVE:To identify optimal strategies to integrate early relational health (ERH) programs in pediatric primary care (PPC) and to describe the development of a best practices toolkit to provide guidance and useful tools that clinicians can use to navigate this process. METHODS:A two-phased approach to develop, assess, and refine a best practices toolkit for the integration of multiple ERH programs in PPC through a modified Delphi process. Phase One included identification and assessment around barriers to ERH program integration and strategies to address them through surveys and focus groups of PPC clinics nationwide. Phase Two then utilized the identified barriers and strategies from Phase One to create a toolkit of best practices on integrating ERH programs in PPC that included two rounds of revision for a final version. RESULTS:126 PPC personnel from 44 clinics nationwide completed the Phase One survey, with respondents reporting many notable strengths and challenges to ERH program integration. 18 survey participants also participated in follow-up focus groups, which reiterated the strengths and challenges found in the surveys. An initial toolkit was then drafted, and experts provided qualitative, free-response feedback around clarity and presentation. Further improvement was made to create the final toolkit, which was rated highly useful and important, though slightly less feasible, by practitioners using formal feedback questions. CONCLUSION/CONCLUSIONS:This study employed a modified Delphi process to create a consensus-based best practices toolkit for integrating multiple ERH programs in PPC to help meet the heterogeneous needs of families to promote optimal child development.

OBJECTIVE/UNASSIGNED:Assessing suicide risk among children is complex, in part due to their developmental differences in identifying, recalling, and verbally describing internal states, alongside cultural differences in how distress is experienced. This study aimed to identify expressions of distress around suicide ideation or attempts through body mapping, a qualitative technique that facilitates both visual and verbal expressions. METHOD/UNASSIGNED: = 16). Children completed the Childhood Suicide Ideation Interview, which included semi-structured questions about their suicide ideation and/or attempt and a body mapping activity, where children illustrated and described their thoughts, feelings, body sensations, and social connections surrounding their suicidal crisis on a printed body silhouette. RESULTS/UNASSIGNED:Analyses conducted with Anthropac yielded 94 expressions of distress. The congruence in overall experiences across children was low (24%), yet specific somatic experiences like "shaking" (70%), "pain" (43%), and "dizziness" (39%) were prevalent. Other frequent experiences included "sad" (48%), "passive suicide ideation" (43%), and "thoughts about family" (39%). CONCLUSIONS/UNASSIGNED:Body mapping was a valuable tool for uncovering unique expressions of distress among ethnoracially diverse children. Somatic expressions, often overlooked in risk assessments, were prominent. Ours and similar studies have the potential to inform the design of culturally and developmentally responsive risk assessment tools and safety planning protocols.

When thoroughly assessed, the prevalence of attention-deficit hyperactivity disorder (ADHD) in children/adolescents is estimated at 5%. There is no evidence that ADHD is over-diagnosed in the UK. Indeed, available data point to under-diagnosis, even though rigorous updated post-COVID-19 pandemic data are not available. Some cases may be misdiagnosed due to low-quality assessment, poor adherence to national guidance or inappropriate differential diagnosis. Beyond the controversy around over- or under-diagnosis and over-medicalisation of ordinary behaviours or emotions, the main issue is that UK clinical services cannot adequately support individuals with ADHD who need help. There is a risk that the narrative claiming 'ADHD is over-diagnosed' could be used to deny people with properly-diagnosed ADHD the care they deserve.

IMPORTANCE/UNASSIGNED:Millions of children worldwide are experiencing prolonged symptoms after SARS-CoV-2 infection, yet social risk factors for developing long COVID are largely unknown. As child health is influenced by the environment in which they live and interact, adverse social determinants of health (SDOH) may contribute to the development of pediatric long COVID. OBJECTIVE/UNASSIGNED:To identify whether adverse SDOH are associated with increased odds of long COVID in school-aged children and adolescents in the US. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cross-sectional analysis of a multicenter, longitudinal, meta-cohort study encompassed 52 sites (health care and community settings) across the US. School-aged children (6-11 years; n = 903) and adolescents (12-17 years; n = 3681) with SARS-CoV-2 infection history were included. Those with an unknown date of first infection, history of multisystem inflammatory syndrome in children, or symptom surveys with less than 50% of questions completed were excluded. Participants were recruited via health care systems, long COVID clinics, fliers, websites, social media campaigns, radio, health fairs, community-based organizations, community health workers, and existing research cohorts from March 2022 to August 2024, and surveys were completed by caregivers between March 2022 and August 2024. EXPOSURE/UNASSIGNED:Twenty-four individual social determinant of health factors were grouped into 5 Healthy People 2030 domains: economic stability, social and community context, caregiver education access and quality, neighborhood and built environment, and health care access and quality. Latent classes were created within each domain and used in regression models. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Presence of long COVID using caregiver-reported, symptom-based, age-specific research indices. RESULTS/UNASSIGNED:The mean (SD) age among 4584 individuals included in this study was 14 (3) years, and 2330 (51%) of participants were male. The number of latent classes varied by domain; the reference group was the class with the least adversity. In unadjusted analyses, most classes in each domain were associated with higher odds of long COVID. After adjusting for many factors, including age group, sex, timing of infection, referral source, and other social determinant of health domains, economic instability characterized by difficulty covering expenses, poverty, receipt of government assistance, and food insecurity were associated with an increased risk of having long COVID (class 2 adjusted odds ratio [aOR], 1.57; 95% CI, 1.18-2.09; class 4 aOR, 2.39; 95% CI, 1.73-3.30); economic instability without food insecurity (class 3) was not (aOR, 0.93; 95% CI, 0.70-1.23). Poorer social and community context (eg, high levels of discrimination and low social support) was also associated with long COVID (aOR, 2.17; 95% CI, 1.77-2.66). Sensitivity analyses stratified by age group and adjusted for race and ethnicity did not alter or attenuate these results. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this study, economic instability that included food insecurity and poor social and community context were associated with greater odds of pediatric long COVID. Those with food security, despite experiencing other economic challenges, did not have greater odds of long COVID. Further study is needed to determine if addressing SDOH factors can decrease the rate of pediatric long COVID.
