Part I of this systematic review summarized the state-of-the-art of pediatric psychopharmacology for Autism Spectrum Disorder (ASD), a severe and lifelong neurodevelopmental disorder. The purpose of this Part II follow-up article is to provide a systematic overview of the experimental psychopharmacology of ASD. To this aim, we have first identified in the Clinicaltrials.gov website all the 157 pharmacological and nutraceutical compounds which have been experimentally tested in children and adolescents with ASD using the randomized placebo-controlled trial (RCT) design. After excluding 24 drugs already presented in Part I, a systematic review spanning each of the remaining 133 compounds was registered on Prospero (ID: CRD42023476555), performed on PubMed (August 8, 2024), and completed with EBSCO, PsycINFO (psychology and psychiatry literature) and the Cochrane Database of Systematic reviews, yielding a total of 115 published RCTs, including 57 trials for 23 pharmacological compounds and 48 trials for 17 nutraceuticals/supplements. Melatonin and oxytocin were not included, because recent systematic reviews have been already published for both these compounds. RCTs of drugs with the strongest foundation in preclinical research, namely arbaclofen, balovaptan and bumetanide have all failed to reach their primary end-points, although efforts to target specific patient subgroups do warrant further investigation. For the vast majority of compounds, including cannabidiol, vasopressin, and probiotics, insufficient evidence of efficacy and safety is available. However, a small subset of compounds, including N-acetylcysteine, folinic acid, l-carnitine, coenzyme Q10, sulforaphane, and metformin may already be considered, with due caution, for clinical use, because there is promising evidence of efficacy and a high safety profile. For several other compounds, such as secretin, efficacy can be confidently excluded, and/or the data discourage undertaking new RCTs. Part I and Part II summarize "drug-based" information, which will be ultimately merged to provide clinicians with a "symptom-based" consensus statement in a conclusive Part III, with the overarching aim to foster evidence-based clinical practices and to organize new strategies for future clinical trials.

BACKGROUND:Children's social-emotional development and mental well-being are critical to adult mental health. However, little is known about the mechanisms or factors that contribute to poor child mental health in low- and middle-income countries. Given the lack of child mental health research to guide interventions or social-emotional learning programs and policy planning, the present study aimed to address these knowledge gaps by examining the psychopathology mechanism involved in the development of childhood mental health problems. METHODS:This cross-sectional study recruited parents (N = 393) whose children attended preschool to primary classes in the Arghakhanchi district of Nepal. Data were gathered through parent interviews. Structural Equation Modeling was used to examine the pathways of the mediational mechanism that examined the influence of parental well-being on parenting and children's mental health outcomes. RESULTS:Approximately 22% of the parents were at risk for moderate to severe mental health problems (anxiety: 24%, depression:19%). Parental mental health problems were higher in families who reported food insecurity, among female parents, less educated parents, and those who perceived themselves on a lower social ladder. Parental mental health, social support, and perceived class were associated with parent-child conflict. Greater parent-child conflict was associated with decreased social competence and increased anger, anxiety, and depression in children. CONCLUSION/CONCLUSIONS:The results partially support the mediational model that Nepali parents' well-being (especially in mental health symptoms, social support, and perception of family's social class domains) is associated with less optimal parenting and, in turn, greater child mental health problems and lower social competence. This study provides new evidence of cross-cultural consistency in child psychopathology and guides the development of evidence-based programs to prevent and promote mental health among Nepali children and families.

PURPOSE/OBJECTIVE:Our goals were to: 1) examine the occurrence of behavioral and emotional symptoms in children on the autism spectrum in a large national sample, stratifying by sex, and 2) evaluate whether children with increased autism-related social communication deficits also experience more behavioral and emotional problems. METHODS: Participants (n = 7,998) were from 37 cohorts from the Environmental influences on Child Health Outcomes (ECHO) Program. Cross-sectional information on demographic factors, parent-report of an ASD diagnosis by clinician, Social Responsiveness Scale (SRS) scores, and Child Behavior Checklist (CBCL) scores were obtained for children aged 2.5-18 years by surveys. We examined mean differences in CBCL Total Problems and DSM-oriented subscale scores by autism diagnosis and by child sex. Analyses using logistic regression were conducted to examine whether autism was associated with higher CBCL scores. We further examined if these relationships differed by child age category (< 6 years, 6-11 years, 12 + years). The relationships between SRS score and CBCL total and subscale scores were examined using quantile regression models, with analyses adjusted for child sex and age. RESULTS: In ECHO, 553 youth were reported by a parent to have a clinician diagnosis of autism spectrum disorder (ASD) (432 [78%] boys and 121 [22%] girls). Youth on the spectrum had higher mean CBCL raw scores on Total Problems and all DSM-oriented subscales compared to those not on the spectrum (all p < 0.0001). Analyses adjusted for sex and stratified by age group indicated that higher odds of autism diagnosis were associated with total, depression, anxiety, and attention-deficit/hyperactivity disorder (ADHD) scales in the top 30% of the CBCL score distribution. Autistic girls were more likely to have parent-reported depression and anxiety compared to autistic boys. In quantile regression analyses, we observed evidence of stronger associations between SRS and CBCL for those in higher quantiles of CBCL total problems scale score (beta representing 1-unit change in SRS associated with 1-unit increase in CBCL total problems scale score), among children in the 70-90th percentile (β = 1.60, p < 0.01), or top 10th percentile (β = 2.43, p < 0.01) of the CBCL total problems scale score distribution. Similar findings were seen for the DSM-oriented depression, anxiety, and ADHD subscales. CONCLUSION/CONCLUSIONS: Results from this large national sample suggest increased behavioral and emotional problems among autistic children compared to non-autistic children throughout early life. Among children on the spectrum this may warrant increased monitoring for co-occurring behavioral and emotional problems.

IMPORTANCE/UNASSIGNED:Delivery of mental health care through telehealth (telemental health care) increased after the onset of the COVID-19 pandemic. Little is known about the speed of adoption (diffusion) of telemental health in the care in the care of individuals with schizophrenia. OBJECTIVES/UNASSIGNED:To characterize telemental health care diffusion in mental health agencies serving Medicaid beneficiaries with schizophrenia and the beneficiary-level association of telemental health care use with race and ethnicity. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This retrospective cohort study used New York State Medicaid data from March 1, 2019, to February 29, 2020 (prepandemic period), and from March 11, 2020, to March 31, 2021 (pandemic period), from 261 agencies serving 30 990 beneficiaries with schizophrenia with 1 or more mental health visits during the pandemic period. Statistical analysis was performed from November 2021 through September 2024. EXPOSURE/UNASSIGNED:Agency percentage of patients belonging to racial and ethnic minority groups among all Medicaid-covered patients between March 2019 and February 2020; agency type, categorized as freestanding, hospital affiliated, or state operated; beneficiary-level race and ethnicity, categorized as Asian or other (American Indian or Alaska Native; Native Hawaiian or Other Pacific Islander), Black, Latinx, White, and unknown; and pandemic severity, operationalized as COVID-19 hospitalization rates per 10 000 population in administratively defined catchment areas. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Days to 10% cumulative telemental health care use within agencies, as well as beneficiary-level time to first telemental health care visit and any telemental health care visit in catchment areas in times of varying pandemic severity. RESULTS/UNASSIGNED:In this cohort study of 261 agencies (18 [7%] state operated, 79 [30%] hospital affiliated, and 164 [63%] free standing) and 30 990 beneficiaries with schizophrenia (mean [SD] age, 43 [13] years; 59% male; 7% Asian or other, 38% Black, 20% Latinx, and 25% White), 6 agencies (2%) never adopted telemental health care, and 248 (95%) reached 10% cumulative telemental health care visits in a mean of 18 days. Mean (SD) agency prepandemic shares of beneficiaries belonging to racial or ethnic minority groups (56% [23%]) were not associated with telemental health care diffusion. Diffusion was faster in state-operated vs free-standing agencies (hazard ratio [HR], 2.44 [95% CI, 1.21-4.95]). Relative to White beneficiaries, time to first telemental health care visit was slower in every racial and ethnic minority group (Asian or other: HR, 0.93 [95% CI, 0.88-0.98]; Black: HR, 0.90 [95% CI, 0.87-0.93]; Latinx: HR, 0.95 [95% CI, 0.91-0.99]). Beneficiaries from at least 1 racial or ethnic minority group were less likely than White beneficiaries to have a telemental health care visit regardless of pandemic severity and area; differences narrowed when pandemic severity was higher (eg, in New York City, the odds ratio of Black beneficiaries having a telemental health care visit relative to White beneficiaries when the pandemic severity was high was 0.70 [95% CI, 0.63-0.79] but decreased to 0.59 [95% CI, 0.53-0.67] when the pandemic severity was low). CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this cohort study of Medicaid beneficiaries with schizophrenia, telemental health care diffused rapidly after the onset of the COVID-19 pandemic, particularly in state-operated agencies. Together, agency-level and beneficiary-level race and ethnicity findings suggest within-agency racial and ethnic differences in diffusion of telemental health care. States should monitor the diffusion of innovations across vulnerable populations.

IMPORTANCE/UNASSIGNED:Amid escalating mental health challenges among young individuals, intensified by the COVID-19 pandemic, analyzing postpandemic trends is critical. OBJECTIVE/UNASSIGNED:To examine mental health care utilization and prescription rates for children, adolescents, and young adults before and after the COVID-19 pandemic. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This population-based time trend study used an interrupted time series analysis to examine mental health care and prescription patterns among the French population 25 years and younger. Aggregated data from the French national health insurance database from January 2016 to June 2023. Data were analyzed from September 2023 to February 2024. MAIN OUTCOMES AND MEASURES/UNASSIGNED:The number of individuals with at least 1 outpatient psychiatric consultation, those admitted for full-time psychiatric hospitalization, those with a suicide attempt, and those receiving psychotropic medication was computed. Data were stratified by age groups and sex. Quasi-Poisson regression modeled deseasonalized data, estimating the relative risk (RR) and 95% CI for differences in slopes before and after the pandemic. RESULTS/UNASSIGNED:This study included approximately 20 million individuals 25 years and younger (20 829 566 individuals in 2016 and 20 697 169 individuals in 2022). In 2016, the population consisted of 10 208 277 of 20 829 566 female participants (49.0%) and 6 091 959 (29.2%) aged 18 to 25 years. Proportions were similar in 2022. Significant increases in mental health care utilization were observed postpandemic compared with the prepandemic period, especially among females and young people aged 13 years and older. Outpatient psychiatric consultations increased among women (RR, 1.13; 95% CI, 1.07-1.20), individuals aged 13 to 17 years (RR, 1.15; 95% CI, 1.06-1.23), and individuals aged 18 to 25 years (RR, 1.08; 95% CI, 1.03-1.14). Hospitalizations for suicide attempt increased among women (RR, 1.14; 95% CI, 1.02-1.27) and individuals aged 18 to 25 years (RR, 1.07; 95% CI, 1.03-1.12). Regarding psychotropic medications, almost all classes, except hypnotics, increased in prescriptions between 2016 and 2022 for females, with a particularly marked rise in the postpandemic period. For men, only increases in the prescriptions of antidepressants (RR, 1.03; 95% CI, 1.01-1.06), methylphenidate (RR, 1.09; 95% CI, 1.06-1.12), and medications prescribed for alcohol use disorders (RR, 1.08; 95% CI, 1.04-1.13) were observed, and these increases were less pronounced than for women (antidepressant: RR, 1.13, 95% CI, 1.09-1.16; methylphenidate: RR, 1.15; 95% CI, 1.13-1.18; alcohol use dependence: RR, 1.12; 95% CI, 1.08-1.16). Medications reserved for severe mental health situations, such as lithium or clozapine, were prescribed more frequently starting at the age of 6 years. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this study, an interrupted time-series analysis found a marked deterioration in the mental health of young women in France in the after the COVID-19 pandemic, accentuating a trend of deterioration that was already observed in the prepandemic period.

OBJECTIVE/UNASSIGNED:Evidence suggests that psilocybin-assisted therapy (PAT) leads to durable shifts in personality structure. However, such changes have yet to be characterized in disorders of addiction. In this secondary analysis from a randomized controlled trial, the authors examined the effect of PAT on personality dimensions in patients with alcohol use disorder (AUD), hypothesizing that PAT would attenuate personality abnormalities in AUD and that reductions in trait impulsiveness would be associated with lower drinking. METHODS/UNASSIGNED:Eighty-four adults with AUD were randomized to two medication sessions of either psilocybin (N=44) or active placebo (diphenhydramine; N=40), received 12 weekly psychotherapy sessions, and completed follow-up for an additional 24 weeks. Changes in personality traits (week 36 vs. baseline) were assessed with the revised NEO Personality Inventory; daily alcohol consumption was quantified using the timeline followback. RESULTS/UNASSIGNED:Relative to the placebo group, the psilocybin group showed significant reductions in neuroticism and increases in extraversion and openness. Secondary analyses showed that reductions in neuroticism were driven by decreases in the facets depression, impulsiveness, and vulnerability; increases in openness were driven by increases in the facets openness toward feelings and fantasy. Across all participants, decreases in impulsiveness were associated with lower posttreatment alcohol consumption, and an exploratory analysis revealed that these associations were strongest among psilocybin-treated participants who continued moderate- or high-risk drinking prior to the first medication session. CONCLUSIONS/UNASSIGNED:PAT elicited durable shifts in personality, suggesting normalization of abnormal personality trait expression in AUD. Further study is needed to clarify whether PAT exerts its beneficial effects by reducing impulsiveness or whether impulsive individuals inherently respond better to PAT.

For many years, the hilus of the dentate gyrus (DG) was a mystery because anatomical data suggested a bewildering array of cells without clear organization. Moreover, some of the anatomical information led to more questions than answers. For example, it had been identified that one of the major cell types in the hilus, the mossy cell, innervates granule cells (GCs). However, mossy cells also targeted local GABAergic neurons. Furthermore, it was not yet clear if mossy cells were glutamatergic or GABAergic. This led to many debates about the role of mossy cells. However, it was clear that hilar neurons, including mossy cells, were likely to have very important functions because they provided strong input to GCs. Hilar neurons also attracted attention in epilepsy because pathological studies showed that hilar neurons were often lost, but GCs remained. Vulnerability of hilar neurons also occurred after traumatic brain injury and ischemia. These observations fueled an interest to understand hilar neurons and protect them, an interest that continues to this day. This article provides a historical and personal perspective into the ways that I sought to contribute to resolving some of the debates and moving the field forward. Despite several technical challenges the outcomes of the studies have been worth the effort with some surprising findings along the way. Given the growing interest in the hilus, and the advent of multiple techniques to selectively manipulate hilar neurons, there is a great opportunity for future research.

BACKGROUND:Sleep problems are reported for up to 80% of autistic individuals. We examined whether parsimonious sets of items derived from the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) and the Brief Infant Sleep Questionnaire (BISQ) are superior to the standard M-CHAT-R in predicting subsequent autism spectrum disorder (ASD) diagnoses. METHODS:Participants from 11 Environmental influences on Child Health Outcomes (ECHO) cohorts were included. We performed logistic LASSO regression models with 10-fold cross-validation to identify whether a combination of items derived from the M-CHAT-R and BISQ are superior to the standard M-CHAT-R in predicting ASD diagnoses. RESULTS:The final sample comprised 1552 children. The standard M-CHAT-R had a sensitivity of 44% (95% CI: 34, 55), specificity of 92% (95% CI: 91, 94), and AUROC of 0.726 (95% CI: 0.663, 0.790). A higher proportion of children with ASD had difficulty falling asleep or resisted bedtime during infancy/toddlerhood. However, LASSO models revealed parental reports of sleep problems did not improve the accuracy of the M-CHAT-R in predicting ASD diagnosis. CONCLUSION/CONCLUSIONS:While children with ASD had higher rates of sleep problems during infancy/toddlerhood, there was no improvement in ASD developmental screening through the incorporation of parent-report sleep metrics. IMPACT/CONCLUSIONS:Parental-reported sleep problems are common in autism spectrum disorder (ASD). We investigated whether the inclusion of parental-reports of infant/toddler sleep patterns enhanced the effectiveness of developmental screening for autism. We reported higher rates of difficulty falling asleep and resisting bedtime during infancy and toddlerhood among children later diagnosed with ASD; however, we did not find an improvement in ASD developmental screening through the incorporation of parent-report sleep metrics. In our sample, the standard M-CHAT-R had a sensitivity of 39% among children of mothers with government insurance compared with a sensitivity of 53% among children of mothers with employer-based insurance.
