This is the first bottom-up review of the lived experience of persons who attempt suicide. The study has been co-designed, co-conducted and co-written by experts by experience and academics, focusing on first-person narratives within and outside the medical field. The lived world of individuals who attempt suicide is characterized by experiences related to the attempt itself ("contemplating suicide as a deliberate death", "contemplating suicide as an escape route", "looking for online answers about suicide", "planning suicide", "finding rest between the suicidal decision and the final act", "changing one's mind during the suicide attempt", "acting on suicidal impulses"); experiences related to the self and time ("feeling unworthy", "feeling detached from oneself or the world and lacking a sense of agency", "splitting the self between the decision to live or die", "perceiving an abortive and doomed future"); and experience of emotions and the body ("feeling overwhelmed by hopelessness and despair", "feeling empty and drained of energy", "feeling alone"). The lived experience of individuals who attempt suicide is also described in terms of the social and cultural context, including the experience of others ("feeling that no one cares", "feeling like a burden to others", "facing others' difficulty in understanding"); cultural, gender and age differences ("experiencing geographical, cultural and religious taboos about suicide", "feeling inadequate in relation to gender stereotypes", "feeling abandoned in old age"); and the perception of stigma ("facing social stigma", "experiencing a stigmatized self", "silencing suicidal behaviors"). The lived experience of persons after an attempted suicide is characterized as a complex process of self-acceptance and rediscovery ("living with suicidal thoughts", "navigating the challenges of recovery", "gaining new perspectives during recovery", "restoring interpersonal relationships to recover"). Finally, the lived experience of individuals who attempt suicide is described with respect to their access to general health care ("seeking help before the suicide attempt", "feeling abandoned after a suicide attempt") and mental health care ("experiencing shame as a barrier to care", "fearing mental disorder label", "feeling accepted and listened to", "facing economic difficulties in accessing support", "coping with distress during hospitalization"). The experiences described in this paper hold educational and social value, informing medical and psychological practices and research, public health approaches, and promotion of social change. This research overcomes embarrassment, fear and stigma, and helps us to understand the fragile nature of our emotions and feelings, our immersion in the social world, and our sense of meaning in life.

External trigeminal nerve stimulation in youth with ADHD: a randomized, sham-controlled, phase 2b trial

Conti, Aldo Alberto; Bozhilova, Natali; Eraydin, Irem Ece; Stringer, Dominic; Johansson, Lena; Marhenke, Robert; Bilbow, Andrea; El Masri, Sahid; Hyde, Joshua; Giaroli, Giovanni; Liang, Holan; Fiori, Federico; Mehta, Mitul Ashok; Santosh, Paramala; Carter, Ben; Cortese, Samuele; Rubia, Katya
External trigeminal nerve stimulation (TNS) received US Food and Drug Administration clearance in 2019 as the first device-based, non-pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD), based on a small pilot sham-controlled randomized controlled trial (RCT) that reported symptom improvement in 62 children with ADHD. Here we conducted a confirmatory multicenter, double-blind, randomized, sham-controlled, parallel-group, phase 2b RCT to investigate short-term and long-term efficacy (6 months) of real versus sham TNS in 150 children and adolescents with ADHD. Participants were randomized to receive real TNS (n = 75, mean age (s.d.) = 12.6 (2.8) years) or sham TNS (n = 75, mean age (s.d.) = 12.6 (2.8) years) nightly for approximately 9 hours for 4 weeks. Bilateral stimulation targeted V1 trigeminal branches using battery-powered electrodes applied to the forehead. Sham TNS delivered 30 seconds of stimulation per hour at lower frequency and pulse width. Intention-to-treat analysis showed no significant differential treatment effects on ADHD symptoms (primary outcome) (estimated adjusted mean difference = 0.83; 95% confidence interval: -2.47 to 4.13; P = 0.622; Cohen's d = 0.09). No serious adverse events were reported, and side effects did not differ between groups. In conclusion, TNS is a safe intervention but does not demonstrate clinical efficacy for pediatric ADHD.

From infant temperament to anxiety: infant neural responsivity to unexpected stimuli shapes outcomes

Xing, Jiayin; Kanel, Dana; Takemoto, Sydney; Valadez, Emilio A; Altman, Kathryn B; Morales, Santiago; Groves, Caroline; Chronis-Tuscano, Andrea; Sylvester, Chad; Pine, Daniel S; Fox, Nathan A; Filippi, Courtney A
BACKGROUND:Negative reactivity (NR) and behavioral inhibition (BI), temperamental traits characterized by novelty-evoked distress and avoidance respectively, represent risk markers for anxiety. However, not all infants with NR and BI develop anxiety. Pathways from infant temperament to anxiety remain underspecified. This study tests the hypothesis that heightened neural sensitivity to unexpected sensory stimuli in infancy moderates risk for anxiety. METHODS:Data from the Temperament Over Time Study (N=291) were utilized. Infants completed laboratory-based assessments of NR at 4 months (M) and BI at 2-3 years. BI was also assessed using parent-report. At 9 and 36M, electroencephalography was collected during a passive three-stimulus auditory oddball task, and the mismatch response (MMR) and novelty P3 were quantified. Adolescent anxiety was measured using parent- and self-reports, and clinical interviews at 13 and 15 years. Structural equational modeling analyses were applied to examine whether infants' MMR or novelty P3 at 9 and 36M modulate relations between NR, BI, and adolescent anxiety. RESULTS:The MMR at 9M moderated the relation between NR and BI, and the MMR at 36M moderated the relation between BI and 13-year anxiety. In both cases, a more negative MMR was associated with elevated risk. This association was not present for attention problems or externalizing outcomes. Additional exploratory analyses showed that the novelty P3 mediated pathways from NR to social anxiety. CONCLUSIONS:Individual differences in the infant's neural response to unexpected stimuli relate to temperamental risk for anxiety.

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.

BACKGROUND:People with mental disorders have an increased risk of diabetes, yet conflicting evidence exists regarding the quality of diabetes care they receive. To address this evidence gap, we conducted a systematic review and meta-analysis to assess and compare diabetes quality of care in people with diabetes with mental disorders versus people with diabetes without mental disorders. METHODS:test, blood pressure measured, foot surveillance, serum creatinine test, serum cholesterol test, BMI recorded, smoking status recorded, retinal monitoring). Secondary outcomes were study-specific diabetes quality of care individual indicators matched to the nine NICE diabetes monitoring indicators and specific diabetes interventions and anti-diabetes medications. We analysed primary and secondary outcomes according to any mental disorder and to specific diagnostic subgroups. Study quality was evaluated using the Newcastle-Ottawa Scale (NOS). FINDINGS/RESULTS:measurement (24 studies, 0·81 [0·68-0·97], p=0·024), retinal screening (21 studies, 0·77 [0·63-0·95], p=0·013), lipid and cholesterol measurement (20 studies, 0·83 [0·69-0·99], p=0·043), foot examination (11 studies, 0·85 [0·76-0·95], p=0·0044), and renal investigation (16 studies, 0·78 [0·63-0·96], p=0·022). A significant positive association was found between any mental disorder and recorded smoking status (two studies, 1·09 [1·02-1·17]; p=0·0076). Any mental disorder was significantly associated with higher odds of receiving insulin (ten studies, 1·52 [95% CI 1·16-1·99]; p=0·0022), but negatively associated with treatment with a GLP-1 receptor agonist (two studies, 0·26 [0·13-0·49]; p<0·0001). There was no evidence of publication bias. INTERPRETATION/CONCLUSIONS:Mental disorders are negatively associated with receiving adequate diabetes monitoring and GLP-1 agonist therapy. Addressing these disparities has the potential to address the increased mortality associated with mental disorders. FUNDING/BACKGROUND:None.

Chemogenetic activation of hippocampal area CA2 promotes acute and chronic seizures in a mouse model of epilepsy

LaFrancois, John J; Kennedy, Meghan; Rathod, Monarchsinh; Santoro, Bina; Lisgaras, Christos Panagiotis; Siegelbaum, Steven A; Scharfman, Helen E
Pyramidal cells (PCs) of hippocampal area CA2 exhibit increased excitability in temporal lobe epilepsy (TLE) and in mouse models of TLE. In epileptic mice, selective inhibition of CA2 PCs reduces chronic seizures. Here we asked if activating CA2 PCs increases seizures. Mice expressing Cre recombinase in CA2 PCs (Amigo2-Cre mice) were injected with the convulsant pilocarpine to induce a period of severe seizures (status epilepticus, SE), which leads to chronic seizures after 3-4 weeks (epilepsy). Epileptic mice were injected with a Cre-dependent adeno-associated virus (AAV) to express an excitatory designer receptor exclusively activated by designer drug (eDREADD; hM3Dq) in dorsal CA2 bilaterally and implanted with subdural EEG electrodes. After recovery, mice were recorded continuously using video and EEG for 6 weeks, 3 weeks with drinking water containing the eDREADD activator clozapine-N-oxide (CNO) and 3 weeks without CNO. CA2 activation with CNO caused a significant increase in seizure frequency and duration. Seizures occurred in clusters (many seizures per day over several consecutive days) and mice given water with CNO had a greater maximum number of seizures per day during a cluster compared to water without CNO. CNO had no significant effect in control mice. In naïve Amigo2-Cre mice expressing hM3Dq, pre-treatment with CNO before pilocarpine administration shortened the latency to SE and increased EEG power at the start of SE. Taken together with prior findings, the results suggest that CA2 is a control point for regulating seizures in the pilocarpine mouse model of TLE.

Female infertility diagnosis and adult-onset psychiatric conditions: a matched cohort study

Ben Messaoud, Khaoula; Zaks, Nina; Licciardi, Frederick; Ramlau-Hansen, Cecilia Høst; Kahn, Linda G; Janecka, Magdalena
STUDY QUESTION/OBJECTIVE:Is there an association between infertility diagnosis and long-term adult-onset psychiatric conditions in women? SUMMARY ANSWER/CONCLUSIONS:Infertility diagnosis in women is linked to higher risks of mood disorders, anxiety- and stress-related disorders, and behavioral syndromes with physical components, but not schizophrenia or other psychotic disorders, particularly notable from 9 years after the first infertility diagnosis. WHAT IS KNOWN ALREADY/BACKGROUND:Infertility, especially in women, is associated with major mental health challenges around the time of diagnosis. However, the long-term connection with a wide range of psychiatric disorders is largely unknown. STUDY DESIGN, SIZE, DURATION/METHODS:This study employed a matched-pair design within the UK Biobank (UKB) cohort, including 3893 females with a diagnosis of infertility and 15 603 matched female controls, totaling 19 496 participants. PARTICIPANTS/MATERIALS, SETTING, METHODS/METHODS:Female UKB participants with a diagnosis of infertility were matched to females without the diagnosis in a 1:4 ratio based on year of birth, index of deprivation of their residency area, and primary care data linkage status. The diagnosis of female infertility was identified by the first occurrence of a primary or secondary diagnosis in either primary care or hospital records. Additional analyses explored interactions between infertility diagnosis and both miscarriage and childbearing status on psychiatric conditions. MAIN RESULTS AND THE ROLE OF CHANCE/RESULTS:Diagnosis of infertility was associated with higher risks of mood disorders, anxiety- and stress-related disorders, and behavioral syndromes with physical components, but not with schizophrenia or other psychotic disorders. The most notable increases in the risk of psychiatric diagnoses were observed 9 years after the first infertility diagnosis. No significant interactions were found between infertility diagnosis and either miscarriage or childbearing status on psychiatric conditions. Sensitivity analysis confirmed the robustness of these associations across different data sources for infertility diagnosis and psychiatric condition ascertainment. LIMITATIONS, REASONS FOR CAUTION/CONCLUSIONS:The study's limitations include the racial homogeneity and the overall healthier status of the UKB cohort compared to the general UK population and the potential underestimation of associations due to misclassification of subfecund women. WIDER IMPLICATIONS OF THE FINDINGS/CONCLUSIONS:These results emphasize the need for integrated mental health support in infertility care and long-term monitoring of infertility patients for psychiatric risks.

Autism Heterogeneity Related to Preterm Birth: Multi-Ancestry Results From the Simons Foundation Powering Autism Research for Knowledge Sample

Chatzigeorgiou, Charikleia; Asgel, Zeynep; Avila, Marina Natividad; Mahjani, Behrang; Khachadourian, Vahe; Souaiaia, Tade; Mullins, Niamh; Janecka, Magdalena
BACKGROUND/UNASSIGNED:Autism spectrum disorder (ASD) shows significant clinical variability, likely due to a combination of genetic and environmental factors. Preterm birth is a known risk factor for ASD, occurring in approximately 13% of diagnosed individuals. While genetic factors contribute to preterm birth in the general population, the relationship between genetic variation, preterm birth, and ASD heterogeneity remains unclear. METHODS/UNASSIGNED:We investigated the genetic factors associated with preterm birth in 31,947 autistic individuals using data from the SPARK (Simons Foundation Powering Autism Research for Knowledge) sample. We conducted 3 ancestry-specific genome-wide association studies for African/African American, admixed American, and non-Finnish European ancestries, followed by a meta-analysis of 3308 preterm cases and 28,639 controls using METAL. Functional mapping and gene-based analyses were performed using FUMA, and genetic correlations were estimated using LDSC and Popcorn. Polygenic risk scores (PRSs) were computed with BridgePRS, using PRS of preterm birth in the general population. RESULTS/UNASSIGNED:Our study identified ancestry-specific genetic loci associated with preterm birth in ASD cases. Although the meta-analysis results were not statistically significant, the estimated single nucleotide polymorphism heritability was 14%, indicating a meaningful contribution of common genetic variants. Across ancestry groups, preterm birth status was not significantly associated with PRSs for any psychiatric or medical conditions analyzed. However, polygenic liability to preterm birth in the general population was linked to several congenital anomalies after multiple testing adjustments. CONCLUSIONS/UNASSIGNED:These findings highlight the importance of diverse ancestries and early-life exposures in understanding ASD heterogeneity. Future research should replicate these findings in larger samples and explore rare variants associated with preterm birth to better understand the relationship between gestational duration and clinical and genetic differences in ASD.

Connectome-based symptom mapping and in silico related gene expression in children with autism and/or attention-deficit/hyperactivity disorder

Segura, Patricia; Pagani, Marco; Bishop, Somer L; Thomson, Phoebe; Colcombe, Stan; Xu, Ting; Factor, Zekiel Z; Hector, Emily C; Kim, So Hyun; Lombardo, Michael V; Gozzi, Alessandro; Castellanos, Xavier F; Lord, Catherine; Milham, Michael P; Di Martino, Adriana
Clinical, neuroimaging and genomics evidence have increasingly underscored a degree of overlap between autism and attention-deficit/hyperactivity disorder (ADHD). This study explores the specific contribution of their core symptoms to shared biology in N = 166 verbal children (6-12 years) with rigorously-established primary diagnoses of either autism or ADHD (without autism). We investigated the associations between inter-individual differences in low motion whole-brain intrinsic functional connectivity (iFC) and dimensional measures of autism and ADHD symptoms indexed by clinician-based observation and parent interview, respectively. Additionally, we explored their linked gene expression patterns in silico. Whole-brain multivariate distance matrix regression revealed a transdiagnostic association between autism severity and iFC of two nodes primarily on the left hemisphere: the middle frontal gyrus of the frontoparietal network and the posterior cingulate cortex of the default mode network. Across children, the greater the iFC between these nodes, the more severe the autism symptoms, even after controlling for ADHD ratings. Results from secondary segregation analyses were consistent with primary findings, underscoring the significance of internetwork iFC for autism symptom severity across diagnoses. No statistically significant brain-behavior relationships were observed for ADHD symptoms. Genetic enrichment analyses of the iFC maps associated with autism symptoms implicated genes known to: (i) have greater rate of variance in autism and ADHD, and (ii) be involved in neuron projections, suggesting shared genetic mechanisms for this specific brain-clinical phenotype. These findings underscore the relevance of transdiagnostic dimensional approaches in linking clinically-defined and observation-based phenomena to shared presentations at the macroscale circuit- and genomic-levels across diagnoses.
