The use of complementary, alternative and integrative medicine (CAIM) is highly prevalent among autistic individuals, with up to 90% reporting having used CAIM at least once in their lifetime. However, the evidence base for the effects of CAIM for autism remains uncertain. Here, to fill this gap, we conducted an umbrella review of meta-analyses exploring the effects of CAIM in autism across the lifespan and developed a web platform to disseminate the generated results. Five databases were searched (up to 31 December 2023) for systematic reviews with meta-analyses exploring the effects of CAIM in autism. Independent pairs of investigators identified eligible papers and extracted relevant data. Included meta-analyses were reestimated using a consistent statistical approach, and their methodological quality was assessed with AMSTAR-2. The certainty of evidence generated by each meta-analysis was appraised using an algorithmic version of the GRADE framework. This process led to the identification of 53 meta-analytic reports, enabling us to conduct 248 meta-analyses exploring the effects of 19 CAIMs in autism. We found no high-quality evidence to support the efficacy of any CAIM for core or associated symptoms of autism. Although several CAIMs showed promising results, they were supported by very low-quality evidence. The safety of CAIMs has rarely been evaluated, making it a crucial area for future research. To support evidence-based consideration of CAIM interventions for autism, we developed an interactive platform that facilitates access to and interpretation of the present results ( https://ebiact-database.com ).

Every wave of preferred substance use in adolescence serves similar developmental functions. The recent explosion among adolescents of electronic nicotine delivery systems (ENDS), popularly known as vaping, offers an opportunity to revisit models of the role of substance use in adolescent development. Social media's rise alongside that of ENDS distinguishes this recent phenomenon from previous historical waves of substance abuse: Vaping was and remains highly integrated into the digital culture, situating social media as a unique window into the adolescent users' subjective experience. To that end, we employ analyses of vaping manifestations within adolescent social media to complement clinical case material. We position adolescent vaping as an action-oriented facilitation of externalization, individuation, and challenge to authority that can precipitate adolescent-adult enactments. We propose that this use-reinforcing developmental function complements other biological and social properties of ENDS to cement its position within contemporary adolescent culture. We suggest that the evolution of adolescents' preferred devices from pens to USB-like devices to round pastel Elf Bar types and new wave cannabis products is driven by this trend's successive approximation to satisfaction of an adolescent developmental demand. While legal and limit-setting efforts to reduce adolescent vaping have been partially successful, we offer this updated developmental model to complement existing public health efforts in reducing adolescent ENDS use through an understanding and integration of its developmental meanings.

Down syndrome (DS), stemming from the triplication of human chromosome 21, results in intellectual disability, with early mid-life onset of Alzheimer's disease (AD) pathology. Early interventions to reduce cognitive impairments and neuropathology are lacking. One modality, maternal choline supplementation (MCS), has shown beneficial effects on behavior and gene expression in neurodevelopmental and neurodegenerative disorders, including trisomic mice. Loss of basal forebrain cholinergic neurons (BFCNs) and other DS/AD relevant hallmarks were observed in a well-established trisomic model (Ts65Dn, Ts). MCS attenuates these endophenotypes with beneficial behavioral effects in trisomic offspring. We postulate MCS ameliorates dysregulated cellular mechanisms within vulnerable BFCNs, with attenuation driven by novel gene expression. Here, choline acetyltransferase immunohistochemical labeling identified BFCNs in the medial septal/ventral diagonal band nuclei of the basal forebrain in Ts and normal disomic (2N) offspring at ~11 months of age from dams exposed to MCS or normal choline during the perinatal period. BFCNs (~500 per mouse) were microisolated and processed for RNA-sequencing. Bioinformatic assessment elucidated differentially expressed genes (DEGs) and pathway alterations in the context of genotype (Ts, 2N) and maternal diet (MCS, normal choline). MCS attenuated select dysregulated DEGs and relevant pathways in aged BFCNs. Trisomic MCS-responsive improvements included pathways such as cognitive impairment and nicotinamide adenine dinucleotide signaling, among others, indicative of increased behavioral and bioenergetic fitness. Although MCS does not eliminate the DS/AD phenotype, early choline delivery provides long-lasting benefits to aged trisomic BFCNs, indicating that MCS prolongs neuronal health in the context of DS/AD.

Lingering effects of the COVID-19 pandemic are still of grave concern to families within the U.S. Latine community, as pre-pandemic disparities in healthcare and economic stability were significantly exacerbated by the global crisis (Martínez et al., 2021). In this mixed-methods study, we interviewed 42 pregnant and postpartum Latine mothers from low-income households living in the New York Metropolitan area to better understand pandemic related challenges and potential sources of support unique to this group of women. First, we identified broad themes related to specific psychosocial stressors impacting Latine mothers and their families. Second, in an effort to investigate coping strategies that may buffer feelings of persistent stress, mothers were divided into sustained-stress and tapered-stress groups based on reported levels of perceived stress during the height of the pandemic (March-April 2020) compared to the time of interview (August-December 2020). These two groups of mothers were significantly different on levels of PTSD symptoms, social support, and perceived discrimination. Notably, mothers in the tapered-stress group who reported lower-levels of stress at the time of interview described experiences of being distracted by daily activities or by family members as a coping mechanism. Together, these findings highlight the need to address structural barriers and improve access to mental health support in order to mitigate continuing sources of pandemic related stressors for Latine families.

OBJECTIVE:To examine the effects of drug treatment for attention deficit/hyperactivity disorder (ADHD) on suicidal behaviours, substance misuse, accidental injuries, transport accidents, and criminality. DESIGN/METHODS:Emulation of target trials. SETTING/METHODS:Linkage of national registers in Sweden, 2007-20. PARTICIPANTS/METHODS:People aged 6-64 years with a new diagnosis of ADHD, who either started or did not start drug treatment for ADHD within three months of diagnosis. MAIN OUTCOME MEASURES/METHODS:First and recurrent events of five outcomes over two years after ADHD diagnosis: suicidal behaviours, substance misuse, accidental injuries, transport accidents, and criminality. RESULTS:90.1 per 1000 person years; incidence rate ratio 0.98, 0.96 to 1.01). The reduced rates were more pronounced among individuals with previous events, with incidence rate ratios ranging from 0.79 (0.72 to 0.86) for suicidal behaviours to 0.97 (0.93 to 1.00) for accidental injuries. For recurrent events, drug treatment for ADHD was significantly associated with reduced rates of all five outcomes, with incidence rate ratios of 0.85 (0.77 to 0.93) for suicidal behaviours, 0.75 (0.72 to 0.78) for substance misuse, 0.96 (0.92 to 0.99) for accidental injuries, 0.84 (0.76 to 0.91) for transport accidents, and 0.75 (0.71 to 0.79) for criminality. CONCLUSIONS:Drug treatment for ADHD was associated with beneficial effects in reducing the risks of suicidal behaviours, substance misuse, transport accidents, and criminality but not accidental injuries when considering first event rate. The risk reductions were more pronounced for recurrent events, with reduced rates for all five outcomes. This target trial emulation study using national register data provides evidence that is representative of patients in routine clinical settings.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Unaccompanied migrant youths often confront traumatic experiences elevating their risk for mental health symptoms. However, United States-based research on mental health services for this population, particularly Indigenous youths, is limited. Objectives were to examine mental health screening and referral, characteristics associated with referrals, and clinical rationale for screening result/referral discordance. METHODS:All unaccompanied migrant youths with pediatric intake visits at a healthcare-legal clinic between 3/2020-2/2023 were included (N=100). Retrospective cohort data were extracted from medical chart and program registry, including pediatricians' rationale for referrals. Chi-square and t-tests were used to compare rates of screening, evaluation, and discordant referrals by sociodemographic characteristics. Logistic regression was used to identify associations with mental health referral. Exploratory analyses examined referrals by Indigenous group. RESULTS:Youths had a mean (SD) age of 17.5 (2.5) years, most were assigned male at birth (66 [66%]), from Central America (83 [83%]), and one-third were Indigenous. Odds of mental health referral were higher for youths who were assigned female at birth (adjusted OR, 3.00 [95% confidence interval, 1.13-7.87), non-Indigenous (adjusted OR, 2.73; 95% confidence interval, 1.01-7.40), and reported more trauma types (adjusted OR, 1.38; 95% confidence interval, 1.02-1.87). One-third of referrals were for trauma or mental health symptoms identified by pediatricians, but not screeners. CONCLUSION/CONCLUSIONS:Most unaccompanied migrant youths had mental health referrals, one-third of which were for mental health symptoms undetected by screeners at pediatric visit. Findings highlight sociodemographic differences in mental health referrals, with non-Indigenous and female youths having higher odds of referral.

While prior research has explored the neurobiological mechanisms underlying adolescent school performance, these mechanisms remain poorly understood in college students. Impulsivity has been highlighted as a key factor affecting academic success; however, its influence on the relationship between school performance and brain structure remains underexplored. In this study, we used a sample of college students to investigate which gray matter volume (GMV) in brain regions was associated with grade point average (GPA), and whether impulsivity mediates these relationships. Our findings revealed correlations between GMV in the caudate nucleus (CN) and cerebellum with GPA. Increased CN was correlated with poorer GPA through higher impulsivity, whereas higher cerebellum was associated with better GPA through lower impulsivity. These results indicate that CN and cerebellum play crucial roles in school performance and associated impulsivity. Various interventions targeting impulsivity, such as therapy, counseling, and medication, could improve educational outcomes by addressing the underlying neurobiological factors.
