National Incidence of Nurse Suicide and Associated Features.

The aim of this study was to estimate the national incidence of nurse suicide. Nurses are at a higher risk of suicide than nonnurses; however, data have been limited since 2018. This study used a retrospective cohort design using 2017-2021 National Violent Death Reporting System suicides. Female nurses had higher suicide rates than female nonnurses in 2018 (incidence rate ratio, 1.21 [95% confidence interval (CI), 1.05-1.39]), 2019 (1.41 [95% CI, 1.23-1.60]), 2020 (1.26 [95% CI, 1.08-1.45]), and 2021 (1.35 [95% CI, 1.17-1.55]), whereas male nurses were comparable with male nonnurses. Nurses had higher odds of mental health problems (adjusted odds ratio, 1.28 [95% CI, 1.13-1.46], P < .001), job problems (1.60 [95% CI, 1.33-1.92], P < .001), and use of poisoning (1.54 [95% CI, 1.37-1.74], P < .001). Nurses had higher odds of using opioids, cardiovascular/diabetic agents, and drugs not prescribed for home use. Female nurses are at a higher risk of suicide than other females. Multimodal nurse suicide prevention strategies remain indicated.

Can large language models be sensitive to culture suicide risk assessment?

AbstractSuicide remains a pressing global public health issue. Previous studies have shown the promise of Generative Intelligent (GenAI) Large Language Models (LLMs) in assessing suicide risk in relation to professionals. But the considerations and risk factors that the models use to assess the risk remain as a black box. This study investigates if ChatGPT-3.5 and ChatGPT-4 integrate cultural factors in assessing suicide risks (probability of suicidal ideation, potential for suicide attempt, likelihood of severe suicide attempt, and risk of mortality from a suicidal act) by vignette methodology. The vignettes examined were of individuals from Greece and South Korea, representing countries with low and high suicide rates, respectively. The contribution of this research is to examine risk assessment from an international perspective, as large language models are expected to provide culturally-tailored responses. However, there is a concern regarding cultural biases and racism, making this study crucial. In the evaluation conducted via ChatGPT-4, only the risks associated with a severe suicide attempt and potential mortality from a suicidal act were rated higher for the South Korean characters than for their Greek counterparts. Furthermore, only within the ChatGPT-4 framework was male gender identified as a significant risk factor, leading to a heightened risk evaluation across all variables. ChatGPT models exhibit significant sensitivity to cultural nuances. ChatGPT-4, in particular, offers increased sensitivity and reduced bias, highlighting the importance of gender differences in suicide risk assessment. The findings suggest that, while ChatGPT-4 demonstrates an improved ability to account for cultural and gender-related factors in suicide risk assessment, there remain areas for enhancement, particularly in ensuring comprehensive and unbiased risk evaluations across diverse populations. These results underscore the potential of GenAI models to aid culturally sensitive mental health assessments, yet they also emphasize the need for ongoing refinement to mitigate inherent biases and enhance their clinical utility.

Prefrontal cortex engagement during an fMRI task of emotion regulation as a potential predictor of treatment response in borderline personality disorder.

Borderline personality disorder (BPD) is a severe mental illness, with high rates of co-morbid depression and suicidality. Despite the importance of optimizing treatment in BPD, little is known about how neural processes relate to individual treatment response. This study examines how baseline regional brain blood oxygen level dependent (BOLD) activation during a functional magnetic resonance imaging (fMRI) task of emotion regulation is related to treatment response following a six-month randomized clinical trial of Dialectical Behavior Therapy (DBT) or Selective Serotonin Reuptake Inhibitor (SSRI) treatment. Unmedicated females with BPD (N = 37), with recent suicidal behavior or self-injury, underwent an fMRI task in which negative personal memories were presented and they were asked to distance (i.e., downregulate their emotional response) or immerse (i.e., experience emotions freely). Patients were then randomized to DBT (N = 16) or SSRI (N = 21) treatment, with baseline and post-treatment depression and BPD severity assessed. BOLD activity in prefrontal cortex, anterior cingulate, and insula was associated with distancing. Baseline BOLD during distancing in dorsolateral, ventrolateral, and orbital prefrontal cortex (dlPFC, vlPFC, OFC) differentially predicted depression response across treatment groups, with higher activity predicting better response in the SSRI group, and lower activity predicting better response in the DBT group. All female samples. Findings indicate that greater prefrontal engagement during emotion regulation may predict more antidepressant benefit from SSRIs, whereas lower engagement may predict better response to DBT. These results suggest different mechanisms of action for SSRI and DBT treatment, and this may allow fMRI to guide individualized treatment selection.

Single Question for Screening Suicide Risk in Patients With Cancer in Nursing Routine Work: A Retrospective Cross-Sectional Study.

To examine the efficacy of the Single Suicide Question, a tactful single-item tool, in assessing suicide risk among cancer patients. Suicide risk screening in cancer patients faces challenges such as cultural, the degree of attention given and the complexity and diversity of assessment methods. An efficient and simple suicide screening tool is needed within the nursing and treatment process. A retrospective cross-sectional study. All data utilised in this study were obtained from assessments conducted by researchers at our institution between March 2018 and August 2023. Retrospectively analysed Single Suicide Question scores from 9703 patients (March 2018-August 2023), with 229 undergoing additional using other established tools (the Patient Health Questionnaire-9, Generalised Anxiety Disorder-7, Distress Thermometer) alongside the Mini International Neuropsychiatric Interview Suicidal Subscale (MINI Suicidal Subscale). These 229 patients were divided into the cut-off determination dataset (174/229) and the validation dataset (55/229) to analyse, validate and compare the screening efficacy, consistency and optimal cut-off points of the tools relative to the MINI Suicidal subscale (golden standard). K-fold cross-validation was employed to assess the stability of the Single Suicide Question and to revalidate its screening efficacy. In cut-off determination dataset, the Single Suicide Question exhibited good screening efficacy and substantial agreement relative to the MINI Suicidal subscale, as validated in the validation dataset, outperforming other tools. The optimal cut-off points of Single Suicide Question for screening moderate or higher and high suicide risk as 2 and 3 respectively. Its stability in K-fold cross-validation further supported its screening efficacy. The Single Suicide Question shows potential as a preliminary screening tool for suicide risk. Furthermore, it has also demonstrated the potential of a simple, tactful, culturally fitting question in assessing suicide risk, providing insight for the development of relevant tools in different cultural and linguistic backgrounds. Our study demonstrates the potential of the Single Suicide Question as a screening tool for identifying suicide risk among cancer patients, which may facilitate efficient suicide screening. Furthermore, it reveals that tactful, culturally fitting, yet simple tools can achieve good screening efficacy, providing insights for the development of similar tools in different cultural and linguistic contexts. This study investigated the effectiveness of using a culturally contextualised, specific single question to screen for suicide risk in Chinese cancer patients, demonstrating high screening efficacy and stability. With further research, this method may provide a tactful, culturally informed and efficient suicide screening approach to address the critical issue of suicide risk in cancer care, and it also serves as a reference for developing similar tools in diverse cultural and linguistic contexts. The study followed the STROBE checklist guidelines for cross-sectional studies. The data provided by patients were the foundation of this study. Nurses played a central role in conducting the majority of assessments and contributing to the research design in this study.

Factors Influencing Suicidal Ideation in Young and Middle-aged Adults in Korea: A Nationwide Study

Abstract Objectives This study aims to analyze various factors influencing suicidal ideation among young (19-39 years) and middle-aged (40-64 years) adults using nationwide longitudinal data in South Korea, which has the highest suicide rate among OECD countries for more than 20 years. Methods An analysis was conducted using the WAVE II data (2016-2017) from a nationwide longitudinal study on the mental health of suicide survivors (LoSS). The sample included 2,002 participants (1,290 young adults, 712 middle-aged adults) recruited through stratified proportional quota sampling. Multiple regression analysis was performed to identify factors influencing suicidal ideation in each age group. Results In young adults, being female, having a high school education or lower, being unmarried/divorced/widowed, and having higher levels of depression were positively associated with suicidal ideation. Higher levels of social support and better subjective physical health were negatively associated with suicidal ideation. In middle-aged adults, being unemployed, living alone, drinking alcohol more than once a week, and having higher levels of depression were positively associated with suicidal ideation, while higher levels of social support were negatively associated with suicidal ideation. Conclusions Factors influencing suicidal ideation differ between young and middle-aged adults. Age-specific suicide prevention strategies considering these factors are needed to promote social health and stability in South Korea. Key messages • Different factors influence suicidal ideation in young and middle-aged adults in South Korea. • Age-specific suicide prevention strategies are necessary to effectively address suicidal ideation and promote social health and stability in South Korea.

Nationwide trends in the suicide mortality among the disabled in Korea from 2006 to 2017

Abstract Aims The disabled are one of the priority populations at risk of suicide, but there has been no study of the factors influencing suicide mortality among the disabled in South Korea. Methods To analyze age-standardized suicide mortality (ICD-10 Codes, X60-84) for each year according to the presence, severity and type of disability, we linked three population datasets (National Health Insurance Claims Database, Disability Registry, and Deaths by Cause). Our dataset covers the entire population of South Korea, extended over a 12-year period from 2006 to 2017. The analyses were stratified by sex, and hazard ratios for suicide were determined by multivariate logistic regression after adjustment for socio-demographic and clinical variables. Results The suicide rate among the disabled was 2.24 times higher than among the non-disabled in 2017. The highest suicide rates were observed among intellectual or mental disabled, and severe disabled. In the disabled group, suicide rates were higher among those with medical benefits, older age (over 70 years), and depressive disorders in both male and female. Conclusions Although the disabled people’s suicide is often seen as an individual problem, it actually affects their families, communities and society. Therefore, government must strive to emphasize the broad view of the disabled population - not just the health of individuals, and track suicide trends and identifying risk and protective factors for suicidal behavior. From this information, suicide prevention strategies for the disabled people should be evaluated to identify the most effective interventions. Financial support: This research was supported by the Basic Science Research Program through the National Research Foundation of Korea funded by the Ministry of Education (No. 2022R1I1A3070074, and 2022R1I1A1A01068449), and a grant of Patient-Centered Clinical Research Coordinating Center funded by the Ministry of Health &amp; Welfare, Republic of Korea (No. HC23C016500). Key messages • The suicide rate among the disabled was 2.24 times higher than among the non-disabled in 2017. • In the disabled group, suicide rates were higher among those with medical benefits, older age (over 70 years), and depressive disorders in both male and female.

Exploring Patient Empowerment in Major Depressive Disorder: Correlations of Trust, Active Role in Shared Decision-Making, and Symptomatology in a Sample of Italian Patients.

Background/Objectives: Empowerment in medicine and psychiatry involves patients gaining control over health-related decisions, improving treatment adherence, outcomes, and satisfaction. This concept is especially significant in psychiatric care due to the complex challenges of mental health conditions, including stigma and impairment of emotional and cognitive functioning. We aim to investigate the correlations between patient trust, decision-making involvement, symptom severity, and perceived empowerment among individuals with Major Depression. Methods: Patients with Major Depressive Disorder were recruited in the "Policlinico G. Rodolico" psychiatry outpatient clinic from November 2022 to June 2023. Inclusion criteria: ages 18-65, ability to consent, stable condition, psychiatric medication history, and recent consultation. Exclusion criteria: psychotic features, bipolar disorder, substance abuse, high suicide risk, and severe comorbidities. Measures included the User Scale for Measuring Empowerment in Mental Health Services (SESM), Trust in Oncologist Scale (TiOS), Clinical Decision-Making Style for Patients (CDMS-P), and Hamilton Depression Rating Scale (HAM-D). Analysis used Kendall's Tau correlation and Two-One-Sided Tests procedure. Results: Seventy-three patients completed the study. No relationship was found between decision-making involvement and perceived empowerment (τ = -0.0625; p = 0.448), or between trust in psychiatrists and empowerment (τ = 0.0747; p = 0.364). An inverse correlation existed between patient involvement in therapy management and trust (τ = -0.2505; p = 0.002). Depression severity inversely correlated with empowerment (τ = -0.2762; p = <.001), but not with trust or decision-making involvement. Conclusions: The lack of significant correlations suggests that decision-making involvement and trust alone may not suffice to enhance empowerment. Trust may encourage patient passivity, while skepticism might drive active involvement. Higher empowerment is associated with less depressive symptoms, highlighting its potential connection with patient outcomes.

Outcomes of the effect of exercise on cognitive function in patients with depression: A meta-analysis.

Major depressive disorder is a common mental disorder, characterized by a high rate of suicide and recurrence, which is frequently accompanied by cognitive impairments, particularly in executive function, memory, attention, and information processing speed. As such, improving the cognitive function in patients with depression and enhancing their quality of life are urgent issues. To perform a systematic review and meta-analysis of the effects of exercise on cognitive function in patients with depression. The PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Medical, VIP, and Biomedical Databases for randomized controlled trials (RCTs) databases were searched (from inception to October 19, 2023) for studies investigating improvements in cognitive function in patients with depression through exercise. Tools recommended by the Cochrane Handbook for RCT evaluation, and GRADEpro and Stata17 software, were employed for risk of bias assessment, evidence grading, forest plot construction, subgroup and sensitivity analyses, and assessment of publication bias. Seventeen RCTs (1173 patients with depression) were included. Exercise had a small but significant positive effect on attention, with an effect size of 0.21, 95%CI: 0.07-0.34, P < 0.01. Specifically, aerobic exercise regimens of 30-60 minute/session, thrice a week, at moderate intensity, and sustained over 3-12 weeks, were associated with the most pronounced benefits (P < 0.05), with effect sizes for executive function, memory, and information processing speed of 0.11, 95%CI: -0.11-0.32, P = 0.34; 0.08, 95%CI: 0.00-0.16, P = 0.05; and 0.14, 95%CI: 0.04-0.25, P = 0.01, respectively. The evidence levels for attention, information processing speed, and memory were rated as 'low,' whereas that for executive function was rated as 'very low'. Exercise could improve attention and information-processing speed in patients with depression, although improvements in executive function and memory are not significant.

Inuit mental health service utilisation in Manitoba: results from the qanuinngitsiarutiksait study

ABSTRACT Despite decades of Inuit accessing services in Manitoba, Inuit-centric services remain scant and have only begun to emerge. This article reports on Inuit utilisation of mental health services in Manitoba. In this study, we focused on two interrelated cohorts: Inuit living in Manitoba and Inuit from the Kivalliq region who come to Winnipeg to access specialised services. We used administrative data routinely collected by Manitoban agencies. The study was conducted in partnership with the Manitoba Inuit Association, and Inuit Elders from Nunavut and Manitoba. Our results show that mental health-related consults represent between 1 in 5 and 1 in 3 of all consults made by Inuit in Manitoba. Rates of hospitalisation for mental health conditions are considerably lower than those of residents from the Manitoba northern health authority. Given that Nunavut has the highest rate of suicide in the world, our results suggest underserved needs rather than lower needs. Kivalliq and Manitoba Inuit utilise mental health services in Manitoba extensively, yet these services for the most part remain western-centric. Epistemological accommodations in the provision of mental health services have yet to be implemented. This is now the focus of our work.

Neme priče: mikrozgodovinski pogled na samomor v sodnih spisih prve polovice 20. stoletja

Based on the archival materials from the Celje and Maribor District Courts (Kreisgerichte) and the specific cases from the Trbovlje County Court (Bezirksgericht), referring to the areas with the highest suicide rates in the Drava Banate, this article examines suicide in the first half of the 20th century. Based on individual cases from judicial practice, as well as newspaper reports, the article sheds light on the social, economic and regional conditions in the considered areas in the first half of the 20th century, as well as the position of women in society and the prevalence of family and sexual violence. At the time when the increasing suicide rates were attributed to the aftermath of World War I, the effects of the economic crisis, and alcoholism, the article analyses the presence and gradual dominance of psychological and psychiatric discourse in determining the causes of individual suicides. By analysing the individual cases, the author presents the attitude towards suicide in rural areas – the shame and stigma still felt by the family members when a relative of theirs commits suicide. The author analyses cases where either the suicide could not be identified or when the corps of the deceased was not found, as well as cases of suicide due to fear and/or shame due to crimes committed. Furthermore, the article focuses on the phenomenon of female suicide and, in this context, on the examples of murder-suicide and the role of women in them, analyses the contemporaneous media discourse, and describes the course of the investigations in the cases where it was not clear whether the death had resulted from suicide or murder.

A Suicide Attempt Multicomponent Intervention Treatment (SAMIT Program): study protocol for a multicentric randomised controlled trial.

Suicide has become a first-order public health concern, especially following the negative impact of COVID-19 on the mental health of the general population. Few studies have analysed the effects of early psychotherapeutic interventions on subjects who have attempted suicide, and even fewer have focused on those hospitalized in non-psychiatric units after a Medically Serious Suicide Attempt (MSSA). The main aim of this study is to describe the protocol designed to evaluate the effectiveness of individual psychological treatment for patients hospitalized after an MSSA. The secondary objectives of the study are: (1) to evaluate the impact on quality of life and other psychosocial variables of patients with a recent MSSA who receive early psychological intervention; (2) to analyse the biological, psychological, and clinical impact of early psychotherapeutic treatment on subjects hospitalized after an MSSA. A longitudinal randomised controlled trial will be conducted with patients over 16 years of age admitted to two general hospitals. The case intervention group will enrol for 8-sessions of individual psychotherapy, Suicide Attempts Multi-component Intervention Treatment (SAMIT), combining Dialectical Behaviour Therapy (DBT), Mentalization-Based Therapy (MBT), and Narrative approaches, while the control group will receive a treatment-as-usual intervention (TAU). Longitudinal assessment will be conducted at baseline (before treatment), post-treatment, and 3, 6, and 12 months after. The main outcome variable will be re-attempting suicide during follow-up. Some psychotherapeutic interventions, usually implemented in outpatient, have proven to be effective in preventing suicidal behaviours. The combination of some of these may be a powerful treatment for preventing future SA in patients hospitalised after an MSSA, which is the most severely suicidal subgroup. Moreover, assessment of the biological, clinical and psychometric impact of this new intervention on patients during the first year after the attempt may help understand some of the multi-level factors associated with the effectiveness of psychotherapeutic interventions in MSSAs. The prevalence of high suicide rates requires the design of effective psychological interventions for their prevention, and also in order to design new pharmacological and psychological treatments. ClinicalTrials.gov ID: NCT06238414. Date of registration: 1st February 2024, final update is protocol version 3.0, 19th March 2024.

Suicide Rates by Age and Time Among American Indian and Alaskan Native Veterans

Objective: Although recent work has highlighted high rates of suicide among American Indian and Alaska Native individuals who served in the US military, to date, a comprehensive evaluation of age-specific suicide rates, over time, has yet to be conducted. Methods: Population-based retrospective cohort study. Average annual suicide rates (2005–2020) were computed. The cohort included 207,955 Native Veterans who were alive as of January 1, 2005, and separated from military service on or before December 31, 2020. Suicide was identified via National Death Index codes. Results: Between 2005 and 2020, average annual, age-specific suicide rates among Native Veterans ranged from 16.32/100,000 (55+ y) to 64.49/100,000 (18–34 y). Compared with other age-related cohorts, the rate among those in the youngest age cohort (18–34y) was the highest between 2005 and 2018. The 2019–2020 average annual rate for 18- to 34-year-olds (41.86/100,000) dropped below that of the middle-aged cohort (35–45 y; 44.66/100,000). Across all age cohorts, firearms were the most used method of suicide [57.2% (18–34 and 35–54 y) to 66.17% (55+y)]; however, a notable percentage of Veterans died by suffocation, 16.54% (55 y and older), 26.71% (35–54 y), and 33.21% (18–34 y). Conclusions: Findings highlight differences in suicide rates by age groups overtime for Native Veterans irrespective of Veterans Health Administration use and across service eras, as well as means of suicide, which also differed across groups. Increased efforts are needed to identify culturally and age-relevant intervention strategies, as well as factors associated with risk, to reduce deaths among Native Veterans.

Validation of the Spanish Version of the Nurses' Global Assessment of Suicide Risk Scale (NGAR) in Nonclinical Settings.

To validate the Nurses' Global Assessment of Suicide Risk (NGASR) in Spanish for an early detection identification of the risk of suicide. A descriptive cross-sectional survey design was used for this work through face-to-face clinical interviews with each participant. Following EQUATOR TRIPOD checklist, the index was translated and administered to a sample of 30 mental health experts and 151 university students. To examine the psychometric properties of the NGASR, the questionnaires also included other standardised scales such as BDI, SBQ and SEEQ. The research was conducted between 2022 and 2023. The content validity index-scale (CVI-S) was 81% and the NGASR presented high reliability with a Kuder-Richardson coefficient of 0.83. Exploratory factor analysis (EFA) returned a six-factor structure for the NGASR items. The results showed that 21.7% of the students assessed had an intermediate to very high suicide risk. This study also revealed that people with mental health problems and depression had a higher risk of suicide. Beyond the sociolinguistic Spanish validation of the scale, it should be noted that it is carried out on a young population in a nonclinical environment, something that many authors have been requesting in their previous validations. The NGASR is a useful prevention tool in university educational settings.

South Korea’s existential public health emergency: Tackling the low birth rate, loneliness, and suicide crisis

South Korea is facing a critical public health emergency characterized by a rapidly declining birth rate, increasing loneliness, and high suicide rates. The fertility rate dropped to 0.72 children per woman in 2023, significantly below the OECD average. This decline is attributed to economic burdens, gender inequality, and changing societal norms. If these trends continue, the youth population could halve by 2040 compared to 2023, severely impacting the nation’s economy and demographic structure. Simultaneously, loneliness has become a significant issue, with over a third of Koreans living alone and a rise in deaths from isolation, particularly among middle-aged and older men. South Korea also faces a severe mental health crisis, marked by high rates of depression and the highest suicide rate among OECD countries for the past 25 years. Troublingly, recent trends indicate an increase in suicides among younger age groups. Efforts to address these issues have included government initiatives for mental health support, but these remain underfunded and insufficient compared to international standards. Additionally, the stigma surrounding mental health persists. South Korea can learn from countries like Japan and the UK, which have implemented successful interventions focusing on social integration and mental health. Addressing these intertwined crises requires collective action and a robust policy response to ensure a sustainable future for South Korea.

Development of a Clinical Guideline for Suicide Prevention in Psychiatric Patients Based on the ADAPTE Methodology.

Suicide is a significant public health issue, with South Korea having the highest suicide rate among Organisation for Economic Cooperation and Development countries. This study aimed to develop clinical guidelines for suicide prevention in psychiatric patients in Korea using the ADAPTE methodology. The development process involved a comprehensive review of literature, expert consultations, and consensus-building using the Nominal Group Technique and Delphi method. The guidelines focus on evidence-based psychiatric treatments, including both pharmacological and non-pharmacological approaches, tailored to the Korean context. Key findings underscoring the need for standardized treatment protocols for patients with major psychiatric disorders, including bipolar disorder, major depressive disorder, and schizophrenia. The guidelines incorporate treatments like lithium, clozapine, atypical antipsychotics, electroconvulsive therapy, and cognitive behavioral therapy, which have shown effectiveness in suicide prevention. Applicability and acceptability within Korea's healthcare system were addressed, ensuring feasibility given the country's medical insurance coverage and accessibility. The guidelines were validated through expert reviews and Delphi rounds, achieving consensus on the final recommendations. The developed guidelines provide a structured, evidence-based approach to reducing suicide rates among psychiatric patients in Korea. Future research will focus on expanding these guidelines to include screening protocols for high-risk groups.

Single-dose psilocybin for U.S. military Veterans with severe treatment-resistant depression – A first-in-kind open-label pilot study

BackgroundThe enduring and severe depression often suffered by Veterans causes immense suffering and is associated with high rates of suicide and disability. This is the first study to evaluate the efficacy and safety of psilocybin in Veterans with severe treatment-resistant depression (TRD). Methods15 Veterans with severe TRD (major depressive episode failing to respond to ≥5 treatments, or lasting >2 years) received 25 mg of psilocybin. Primary outcome was change in Montgomery-Åsberg Depression Rating scale (MADRS) at 3 weeks posttreatment. Response was defined s ≥ 50 % reduction in MADRS, and remission as ≤10 MADRS score. Psychedelic experience was assessed using the Five-Dimensional Altered States of Consciousness scale (5D-ASC). Safety measures included assessment of suicidality and adverse events. Participants on antidepressants were tapered to avoid drug interactions. ResultsOf 15 participants, 60 % met response and 53 % met remission criteria at Week 3. At 12 weeks, 47 % maintained response, and 40 % remission. Co-morbid PTSD did not significantly influence study outcomes. The psychedelic experience reported in 5D-ASC did not correlate with response. Participants judged to need antidepressants were restarted and considered non-responders from that timepoint (n = 4). No unexpected adverse events occurred. LimitationsLimitations include the small sample size, and the uncontrolled and unblinded nature of the study. ConclusionsIn this first study on psilocybin for Veterans with severe TRD, a surprising response and remission was seen. Many Veterans had PTSD though no moderating impact of response was observed. The degree of psychedelic experience did not correlate with depression changes. Further study is warranted.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04433858.

Explorando la salud mental en prisión: un análisis en el Programa de Atención Integral al Enfermo Mental (PAIEM)

Around 3.6% of the 11 million people incarcerated worldwide suffer from psychotic disorders, representing a prevalence four times higher compared to the general population. This phenomenon is linked to high rates of suicide among inmates, an increased risk of premature death after release, and a heightened likelihood of reoffending. In response to this reality, Spanish Penitentiary Institutions initiated a program in 2009 aimed at the comprehensive care of inmates with Severe Mental Disorders. The objective of this pilot study is to explore how anxiety, depression, and trauma-related disorders can affect inmates in two prisons in Lugo, gathering initial data to better understand the mental health challenges facing this population. The results revealed significant differences in the variables of anxiety, depression, and experiences of abuse, highlighting the importance of considering these factors in mental health care within the prison environment. These findings lay the groundwork for future research and advocate for more effective policies and programs to ensure adequate care in prisons.

The Impact of Pain, Threat Perception and Emotional Distress on Suicide Risk in Individuals with Colorectal Cancer.

Colorectal cancer (CRC) can significantly impact mental health, increasing suicide risk. Variables such as pain and threat perception may be crucial. This study aims to identify predictors of suicide risk in individuals with CRC. A total of 71 participants (76.06% men) aged 27 to 88 years (M = 65.18, SD = 12.02) were assessed using the SF-36 for pain, the Brief Illness Perception Questionnaire (B-IPQ) for threat perception, the Hospital Anxiety and Depression Scale (HADS) for emotional distress, and the Plutchik suicide risk scale for suicide risk. Descriptive, comparative, and correlational analyses were performed, followed by a linear regression analysis. Nearly 20% of participants exhibited high suicide risk. There was a moderate-to-high association between suicide risk and the perception of threat, pain, and emotional distress. The linear regression model explained 39% of the variance in suicide risk, with threat perception, pain, and emotional distress as significant predictors. These results indicate the need for multidisciplinary care for individuals with CRC, including emotional support from health psychologists, and holistic, human-centered care from nursing and medical professionals. Future research is necessary to further explore these relationships and improve patient care strategies.

Suicidality, perceived chronic stress, and stress-induced cortisol changes of individuals with schizophrenia.

The associations of suicidality with stress are poorly studied in schizophrenia. The study aimed to determine whether suicidality was correlated with perceived chronic stress and the cortisol fluctuations under stress tasks in schizophrenia. High suicidality was defined as a lifetime history of suicide attempts or suicidal ideation in the past 2weeks. Individuals with schizophrenia and high suicidality (SZ-HS, n=59), with low suicidality (SZ-LS, n=207), and healthy controls (HC, n=196) finished the Perceived Stress Scale. Then, they participated in an experiment that induced stress using the Paced Auditory Serial Addition Task and the Mirror Tracing Persistence Task. Negative affect was measured at baseline and after finishing each task. The salivary cortisol was collected before-, after 20min, and after 40min of the tasks. SZ-HS had elevated perceived stress than SZ-LS and HC. Mixed effect models showed that stress tasks induced cortisol changes in all groups; cortisol of SZ-LS was reduced more than HC, but SZ-HS and SZ-LS did not differ in cortisol fluctuations. SZ-HS and SZ-LS experienced similar negative affect changes during tasks and the difference in withdrawal rates was nonsignificant. SZ-HS had an increased error rate than SZ-LS. In conclusion, suicidality was correlated with high-level perceived stress but did not result in differences in cortisol reactivities under stress tasks. It suggests the inconsistency between appraisal of stress and biological stress system disturbance among SZ-HS compared to SZ-LS.
