BACKGROUND:Adolescents in low- and middle-income countries (LMICs) face significant mental health challenges, yet their perspectives are often underrepresented in the design of preventive strategies. Co-design approaches, such as human-centered design (HCD), offer a promising way to tailor interventions and implementation strategies to adolescents’ needs and local context. In LMICs, these methods require careful adaptation to address resource constraints, limited design literacy, and cultural norms. This study documents how HCD was adapted to engage adolescents in northern Ghana as co-designers of school-based mental health preventive strategies. METHODS:Guided by the first two phases of HCD, we conducted two workshops with 24 students from 12 public senior high schools in Tamale, Ghana. Workshop 1 (Inspiration) used structured, case-based discussions informed by the Consolidated Framework for Implementation Research (CFIR) to explore adolescents’ perspectives on mental health. Workshop 2 (Ideation) used interactive choice-based activities to elicit youth-generated strategies. To align with cognitive and sociocultural factors, we incorporated scaffolded facilitation, hands-on activities, and peer-led engagement. Qualitative data from facilitator notes, artifacts, and audio-confirmed summaries were synthesized using structured rapid qualitative analysis. RESULTS:Adolescents identified key mental health concerns, including stigma, peer and family influences, and fears about confidentiality. Gender-specific discussions revealed culturally rooted concerns, such as peer pressure and substance use among boys and limited support-seeking among girls. Adolescents prioritized five school strategies: teacher training, curricular integration, mentorship programs, activities that promote positive thinking and mindfulness, and entertainment-based mental health education. Youth demonstrated a conceptual shift from viewing mental health as an individual problem to a shared responsibility across schools and communities. Formation of an Adolescent Advisory Board reflected youth interest in sustained leadership and co-design. CONCLUSIONS:Contextualized co-design methods can meaningfully engage adolescents in LMIC settings and support the development of culturally grounded, feasible, and youth-prioritized mental health strategies. Structured facilitation enhances both the inclusivity and authenticity of adolescent engagement. This study contributes to implementation science by presenting a replicable co-design framework with policy relevance and providing a foundation for multilevel intervention development in resource-constrained educational systems.

Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. Primary outcomes were change in disease-specific symptoms and all-cause discontinuation. Standardized mean differences (SMD) and relative risk (RR) were estimated using random-effects meta-analysis. Risk of bias (RoB) was assessed with Cochrane's RoB-tool version 2 and certainty of evidence with GRADE. The review is maintained as living systematic review (https://ebipsyche-database.org/). We included 30 RCTs (1480 participants; female=45.8 %; with psychological support=83.3 %; high RoB=83.3 %). In post-traumatic stress disorder (PTSD), MDMA reduced PTSD symptoms compared to any control (k = 11; SMD=-0.85 [-1.09; -0.60]; I²=0 %; GRADE=low). In major depressive disorder (MDD), psilocybin/ayahuasca/LSD reduced depressive symptoms (k = 8; SMD=-0.62 [-0.97; -0.28]; I²=55 %; GRADE=very low). In anxiety disorders, both MDMA and serotonergic psychedelics reduced anxiety symptoms (SMD_MDMA=-1.18 [-2.04; -0.32]; I²=0 %; k = 2; GRADE=low and SMD_serotonergic=-0.88 [-1.70; -0.06]; I²=54 %;k = 5; GRADE=very low). In alcohol use disorder, neither psilocybin nor LSD reduced abstinence rates (k = 6; RR=1.42 [0.89; 2.26]; I²=7 %; GRADE=very low). In attention-deficit hyperactivity disorder (ADHD), LSD did not reduce ADHD symptoms (k = 1; SMD=0.22 [-0.32; 0.76]; GRADE=very low). Moderate certainty in evidence was only found for MDMA on PTSD symptoms when compared to placebo. MDMA/serotonergic psychedelics were not associated with higher risk of all-cause discontinuation (RR_MDMA=0.74 [0.32; 1.72]; RR_serotonergic=0.81 [0.56; 1.15]). Overall, MDMA/serotonergic psychedelics are promising for the treatment of PTSD, MDD, and anxiety disorders with moderate to large effect sizes. Pragmatic trials, long-term, head-to-head trials exploring the role of psychological support, aiming to identify predictors of response, and accounting for expectancy and functional unblinding are needed. Studies addressing these limitations will likely be required for regulatory approval of psychedelic drugs.

Interoceptive accuracy, the ability to correctly perceive internal body signals such as heartbeats, has been empirically and theoretically linked to stress. However, issues with the measurement of both interoceptive accuracy and stress have led to lack of clarity regarding this relationship. This systematic review and meta-analysis aimed to clarify whether interoceptive accuracy is associated with different facets of stress, including - physical, cognitive and self-reported stressors and the physiological stress response. A systematic search identified 2014 abstracts. Twenty-eight authors were contacted to request data for eligible studies, which yielded a final sample of 20 studies. Results revealed a positive association between heartbeat counting task (HCT) performance and acute physical stressors, and a negative association between HCT performance and physiological stress responses. No significant relationships were observed between stress and interoceptive accuracy assessed by the heartbeat discrimination task. While these findings offer tentative support for stress-interoceptive accuracy associations, they must be interpreted with caution given substantial heterogeneity in stress measures, limited use of interoception tasks beyond the HCT, and ongoing concerns regarding task validity. Implications for future research and methodological recommendations are discussed.

Advanced EEG technology has revealed that epileptiform activity occurs more frequently in Alzheimer's disease (AD) than previously recognized, prompting debate over the utility of EEG in AD diagnostics. Yet, unlike epilepsy, epileptiform activity is not always observed in AD, leading to skepticism. Historically, this absence has been attributed to limited recording depth or insufficient recording duration. We tested an alternative hypothesis that certain types of epileptiform activity, specifically high-frequency oscillations (HFOs, defined as 250-500Hz fast ripples), inhibit interictal spikes (IIS), which are currently used to assess hyperexcitability clinically. We recorded wideband (0.1-500Hz) hippocampal local field potentials in three AD (Tg2576, Presenilin 2^-/-, Ts65Dn Down syndrome model) and two epilepsy (intrahippocampal kainic acid, pilocarpine) mouse models during wakefulness and sleep. In both AD and epilepsy, HFOs consistently outnumbered IIS across behavioral states, age and recording contact. However, IIS and HFOs showed divergent relationships: a negative correlation between their rates was observed only in AD, in contrast to a positive correlation in epilepsy. HFOs preceded IIS at much shorter intervals in epilepsy than in AD. Co-occurrence of IIS with ripples did not differ between AD and epilepsy. These findings reveal a novel dissociation between clinically-relevant EEG biomarkers in AD and epilepsy. In AD, HFOs may inhibit IIS, which could lead to underestimation of hyperexcitability and hinder patient stratification for anti-seizure therapies. While non-invasive HFO detection remains challenging, we stress the need for wideband EEG/MEG, particularly in AD, to assess the full extent of hyperexcitability and biomarker interactions that would otherwise remain undetected.

IMPORTANCE/UNASSIGNED:The comparative effectiveness of 2 transitions of care programs for improving health status and reducing readmissions among patients hospitalized with heart failure is unknown. OBJECTIVE/UNASSIGNED:To compare the effectiveness adding mobile integrated health (MIH) to a transitions of care coordinator for improving health status and reducing 30-day all-cause readmissions among patients discharged after heart failure. DESIGN, SETTINGS, AND PARTICIPANTS/UNASSIGNED:The Mighty-Heart randomized clinical trial included Medicare- or Medicaid-enrolled adult (≥18 years) patients hospitalized with heart failure in 11 New York City (New York) hospitals between January 2021 and September 2024. Participants were randomized 1:1 to MIH or TOCC. TOCC provided a follow-up call by a nurse 48 to 72 hours after discharge. MIH included the same TOCC postdischarge call, and added ongoing nurse care coordination, community paramedic home visits, and facilitated synchronous telehealth with emergency medicine physicians. Data analysis occurred between September 2024 and June 2025. INTERVENTIONS/UNASSIGNED:Receiving MIH plus TOCC or TOCC alone during the first 30 days after hospital discharge. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Coprimary outcomes were health status at 30 days measured with the Kansas City Cardiomyopathy Questionnaire Overall Summary score, and 30-day all-cause hospital readmission, with heart failure-specific readmissions as a secondary outcome. RESULTS/UNASSIGNED:Among 2003 participants (median [IQR] age, 67 [58-78] years; 1040 female [52%]), no adjusted differences were observed in the Kansas City Cardiomyopathy Questionnaire Overall Summary score at 30 days between MIH and TOCC groups (mean difference, 1.83; 95% CI, -0.75 to 4.40; P = .16). Exploratory analysis showed a significant age-by-treatment interaction effect, with younger participants who received MIH having larger improvement in health status (β: 4.40; 95% CI, 1.01 to 7.79). There were no significant differences in overall 30-day readmissions between study groups (20.3% vs 20.4%; odds ratio, 0.99; 95% CI, 0.83 to 1.19; P = .95). CONCLUSIONS AND RELEVANCE/UNASSIGNED:This randomized clinical trial found that MIH conferred no additional benefit on health status or 30-day readmissions for postacute patients with heart failure compared to TOCC alone. Preliminary subgroup analyses suggest potential variations in MIH effects by age and sex; therefore, further research is warranted. TRIAL REGISTRATION/UNASSIGNED:ClinicalTrials.gov Identifier: NCT04662541.

IMPORTANCE/UNASSIGNED:Individuals with attention-deficit/hyperactivity disorder (ADHD) may present with psychosis or bipolar disorder (BD) following treatment with stimulants. The extent to which this occurs is currently unclear. OBJECTIVE/UNASSIGNED:To meta-analytically quantify the occurrence of psychosis or BD after exposure to stimulants in individuals with ADHD and assess possible moderating factors. DATA SOURCES/UNASSIGNED:PubMed, Web of Science, Ovid/PsycINFO, and Cochrane Central Register of Reviews were searched from inception until October 1, 2024, without language restrictions. STUDY SELECTION/UNASSIGNED:Studies of any design with DSM or International Classification of Diseases-defined ADHD populations exposed to stimulants, where psychosis or BD outcomes were evaluated. DATA EXTRACTION AND SYNTHESIS/UNASSIGNED:PRISMA Preferred Reporting Items for Systematic Reviews and Meta-analyses and MOOSE Meta-analysis of Observational Studies in Epidemiology guidelines were followed, the protocol was registered, and the Newcastle-Ottawa scale and Cochrane risk of bias-2 tool were used for quality appraisal. Random-effects meta-analysis, subgroup analyses, and meta-regressions were conducted. MAIN OUTCOMES AND MEASURES/UNASSIGNED:For the proportion of individuals developing psychotic symptoms, psychotic disorders, and BD, effect sizes are reported as percentages with 95% CIs. For the comparison between amphetamines and methylphenidate, effect sizes are presented as odds ratios with 95% CIs. RESULTS/UNASSIGNED:Sixteen studies (N = 391 043; mean [range] age, 12.6 [8.5-31.1] years; 288 199 [73.7%] male) were eligible. Among individuals with ADHD prescribed stimulants, 2.76% (95% CI, 0.73-9.88; k = 10; n = 237 035), 2.29% (95% CI, 1.52-3.40; k = 4; n = 91 437), and 3.72% (95% CI, 0.77-16.05; k = 4; n = 92 945) developed psychotic symptoms, a psychotic disorder, and BD, respectively. Heterogeneity across the studies was significant (I2 > 95%). Psychosis occurrence risk was significantly higher in individuals exposed to amphetamines than to methylphenidate (odds ratio [OR], 1.57, 95% CI, 1.15-2.16; k = 3, n = 231 325). Subgroup analyses showed significantly higher prevalence of psychotic symptoms in studies from North America and in those with longer follow-up periods. Increased psychosis occurrence was associated with a higher proportion of female participants, smaller sample sizes, and higher dose of stimulants. CONCLUSIONS AND RELEVANCE/UNASSIGNED:This systematic review and meta-analysis found a nonnegligible occurrence of psychotic symptoms, psychotic disorders, or BD in individuals with ADHD treated with stimulants. Amphetamines were associated with higher occurrence compared to methylphenidate. The included studies cannot establish causality, highlighting the need for further research, including randomized clinical trials and mirror-image studies comparing individuals exposed and not exposed to stimulants. Nonetheless, clinicians should inform patients about the increased occurrence of psychosis or BD when discussing stimulant pharmacotherapy and systematically monitor for these conditions throughout treatment.

BACKGROUND:Maternal infections are linked to neurodevelopmental impairments, highlighting the need to investigate SARS-CoV-2-induced immune activation. OBJECTIVE:This study aimed to evaluate the impact of maternal infection on neurodevelopment and investigate whether cytokine and chemokine profiles predict delays at 24 months. METHODS:Conducted in Brazil (January 2021-March 2022), this follow-up study included 18 SARS-CoV-2 positive pregnant women at 35-37 weeks' gestation, 15 umbilical cord blood samples, and blood samples from 15 children at 6 months and 14 at 24 months. Developmental delay was defined using the Bayley Scales of Infant and Toddler Development, Third Edition, with scores below 90 in cognitive, communication, or motor domains. RESULTS:At 6 months, 33.3% of infants exhibited cognitive delays, 20% communication delays, and 40% motor delays, increasing to 35.71%, 64.29%, and 57.14% at 24 months, respectively. Elevated interferon-gamma and tumor necrosis factor-alpha in cord blood correlated with cognitive delays, while interleukin (IL)-6, IL-8, IL-17, and IL-1β were associated with motor delays. Increased C-X-C motif chemokine ligand 10 and other cytokines were associated with communication delays. CONCLUSION/CONCLUSIONS:Maternal SARS-CoV-2 may impact infant neurodevelopment, as early cytokine elevations correlate with delays, highlighting the importance of early monitoring and interventions to reduce long-term effects. IMPACT/CONCLUSIONS:Prenatal SARS-COV-2 infection in pregnant women is linked to developmental delays in toddlers, with cytokine and chemokine changes associated with neurodevelopmental outcomes at 24 months. This study shows the long-term impact of maternal SARS-COV-2 infection on child development, highlighting inflammatory markers like IFN-γ, TNFα, IL-6, IL-8, IL-17, IL-1β, and CXCL10. Identifying specific cytokines correlating with cognitive, communication, and motor delays suggests potential biomarkers for early intervention. Conducted in Fortaleza, Brazil, the study emphasizes understanding local epidemiological impacts on child development, especially in regions with high infection rates. Graphical depiction of the SARS-CoV-2-induced maternal immune activation and its impact on the child's neurological development. Maternal immune activation from SARS-CoV-2 infection can affect a baby's neurological development, leading to motor, communication, and cognitive delays, assessed at 6 and 24 months old. Alterations in cytokine and chemokine levels in cord blood at six months may help predict these adverse outcomes observed at 24 months.

Parental reflective functioning (PRF) refers to a parent's ability to understand their own and their child's mental states and connect them to behaviors. This longitudinal study evaluated (1) associations among prenatal PRF, using the Pregnancy Interview, demographics, prenatal maternal depressive symptoms, and maternal-fetal attachment and (2) whether prenatal PRF predicted parenting quality assessed during unstructured and challenging mother-child interaction tasks beyond infancy, after controlling for cumulative risk. Data were collected in an urban community sample of women in the midwestern US. Prenatal PRF was positively associated with maternal educational attainment and negatively associated with cumulative demographic risk, but not with depressive symptoms or maternal-fetal attachment. Controlling for cumulative risk, hierarchical regressions showed that prenatal PRF was the sole significant predictor of positive parenting at 36 months, observed during a challenging teaching task but not during free play. Prenatal PRF did not predict negative parenting. These patterns persisted when analyses were repeated within a subsample of Black mothers, with PRF again being the sole significant predictor of positive parenting. Further attention to cultural variations in PRF and parenting in future research is warranted.

Narrative is an important communication skill for sharing personal experiences and connecting with others. Narrative skills are often impacted in autism spectrum disorder (ASD) and have important consequences for social interactions and relationships. Subtle differences in narrative have also been reported among first-degree relatives of autistic individuals, suggesting that narrative may also be an etiologically important language-related skill that is influenced by genes associated with ASD. This study examined narrative ability and related visual attention during narration in ASD and first-degree relatives of individuals with ASD (siblings and parents) to understand how narrative and related attentional styles may be variably impacted across the spectrum of ASD genetic influence. Participants included 56 autistic individuals, 42 siblings of autistic individuals, 49 controls, 161 parents of autistic individuals, and 61 parent controls. Narratives were elicited using a wordless picture book presented on an eye tracker to record concurrent gaze. Findings revealed parallel patterns of narrative differences among ASD and sibling groups in the use of causal language to connect story elements and the use of cognitive and affective language. More subtle differences within the domain of causal language were evident in ASD parents. Parallel patterns in the ASD and sibling groups were also found for gaze during narration. Findings implicate causal language as a critical narrative skill that is impacted in ASD and may be reflective of ASD genetic influence in relatives. Gaze patterns during narration suggest similar attentional mechanisms associated with narrative among ASD families.
