A call to action: informing research and practice in suicide prevention among individuals with psychosis. Front Psychiatry 2024; 15:1378600. [PMID: 38711871 PMCID: PMC11073495 DOI: 10.3389/fpsyt.2024.1378600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 03/22/2024] [Indexed: 05/08/2024] Open
Abstract
Although it is well established that individuals living with psychosis are at increased risk for suicidal ideation, attempts, and death by suicide, several gaps in the literature need to be addressed to advance research and improve clinical practice. This Call-to-Action highlights three major gaps in our understanding of the intersection of psychosis and suicide as determined by expert consensus. The three gaps include research methods, suicide risk screening and assessment tools used with persons with psychosis, and psychosocial interventions and therapies. Specific action steps to address these gaps are outlined to inform research and practice, and thus, improve care and prognoses among persons with psychosis at risk for suicide.

Preadolescent Suicidal Thoughts and Behaviors: An Intensive Longitudinal Study of Risk Factors. J Am Acad Child Adolesc Psychiatry 2024:S0890-8567(24)00184-9. [PMID: 38604472 DOI: 10.1016/j.jaac.2024.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 03/06/2024] [Accepted: 04/02/2024] [Indexed: 04/13/2024]
Abstract
OBJECTIVE Dramatic increases in rates of suicidal thoughts and behaviors (STBs) among youth highlight the need to pinpoint early risk factors. This study used intensive longitudinal sampling to assess what the concurrent associations were between risk factors and STB status, how proximal changes in risk factors were related to STB status, and how risk factors prospectively predicted changes in STB status in a preadolescent sample enriched for early childhood psychopathology. METHOD A total of 192 participants were included from the Parent-Child Interaction Therapy-Emotional Development (PCIT-ED) Study, a longitudinal study of children with and without preschool depression. Participants 7 to 12 years of age completed a diagnostic interview, followed by 12 months of intensive longitudinal sampling, assessing experiences of suicidal ideation and 11 psychosocial variables with known links to STBs in adolescents and adults. Preadolescents with STB history (high-risk) received surveys weekly, and those without STB history (lower-risk) received surveys monthly. RESULTS Female sex, elevated depressive symptoms, greater use of expressive suppression and rumination, emotional clarity, and perceived burdensomeness were uniquely concurrently associated with the likelihood of STB endorsement. Within the high-risk group, (1) increases in depression, expressive suppression, rumination, and perceived burdensomeness, and decreases in positive affect from weekt to weekt+1 were associated with a higher likelihood of a positive STB status at weekt+1; and (2) higher expressive suppression, perceived burdensomeness, and caregiver criticism and conflict at weekt compared to participants' mean levels prospectively predicted increases in the likelihood of a positive STB report from weekt to weekt+1. CONCLUSION Psychosocial factors influencing STBs in adolescents and adults also affect preadolescents in day-to-day life. Expressive suppression and perceived burdensomeness consistently emerged as novel risk indicators and potential targets for treatment. In addition, increases in depression, rumination, and caregiver criticism and conflict, as well as decreases in positive affect, might prompt heightened STB screening and assessments for preadolescents with a history of STBs.

Beyond sleepless nights: Unraveling the complexity of alexithymia and suicide risk among university students. Brain Behav 2024; 14:e3476. [PMID: 38622877 PMCID: PMC11019149 DOI: 10.1002/brb3.3476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 11/21/2023] [Accepted: 03/13/2024] [Indexed: 04/17/2024] Open
Abstract
BACKGROUND There is a solid relationship between alexithymia and suicide risk. Nonetheless, the specific impact of alexithymia's distinct subscales on suicide risk has received the attention it deserves. This article presents a comprehensive exploration of suicide risk among university students, focusing on the interconnections among alexithymia, insomnia, and suicidal behavior. Three components of alexithymia including difficulties in describing emotions or feelings (DDF), difficulties in identifying emotions or feelings (DIF), and the externally oriented thinking were considered. METHODS The study involved 208 participants from a Persian university sample, examining the significance of incorporating both alexithymia and insomnia in suicide risk assessment and intervention planning. Insomnia was positioned as a pivotal mediator. A secure electronic link in the Telegram application was employed to collect the data. Both linear and nonlinear prediction models were used to explore potential associations among alexithymia, insomnia, and suicide risk. RESULTS The study revealed substantial positive correlations between alexithymia and suicide risk, as well as between insomnia and suicide risk. Additionally, specific components of alexithymia exhibited noteworthy links to suicide risk. The inclusion of insomnia scores in suicide risk predictions is critical, as it greatly enhances the precision of risk assessments and facilitates the design of targeted and effective therapeutic interventions. The association between alexithymia and suicide risk showed a significant relationship (r = .29, p < .01). Moreover, a significant correlation was observed between alexithymia and insomnia (r = .32, p < .01). Additionally, insomnia exhibited a significant positive correlation with suicide (r = .35, p < .01). Interestingly, DDF and DIF showed positive correlations with suicide (r = .28, p < .01; r = .33, p < .01). CONCLUSION The findings carry profound implications for suicide prevention efforts, providing valuable insights to safeguard the well-being and resilience of university students facing suicide risk challenges.

Familial Resilience in Crisis: Navigating the Mediating Landscape of Depressive Symptoms Between Uncertainty Stress and Suicide Behavior Among Chinese University Students. Psychol Res Behav Manag 2024; 17:283-294. [PMID: 38287991 PMCID: PMC10823871 DOI: 10.2147/prbm.s445252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/15/2024] [Indexed: 01/31/2024] Open
Abstract
Background Previous findings indicate that stress has a profound influence on suicide behavior, but the potential mediating and moderating mechanisms are unknown between uncertainty stress and suicide behavior. The present study, therefore, examined the relationship between uncertainty stress and suicide behavior, the mediating effect of depressive symptoms, and the moderating effect of family relationship in a sample of university students in China. Methods 1828 university students were assessed anonymously by using the Uncertainty Stress Scale, Center for Epidemiologic Studies Depression Scale, Brief Suicidal Scale, and Family Relationship Scale between May to June in 2021. SPSS 26.0 was used for descriptive statistics and Spearman correlation analysis. PROCESS 3.5 was used to calculate the significance of the mediating and moderating effects of the variables. Results Moderated mediation model analyses showed that: (a) depressive symptoms partially mediated the link between uncertainty stress and suicide behavior (indirect effect = 0.14, 95%bootstrap CI = 0.10, 0.19). The indirect effect of the depressive symptoms accounted for 67.12% of the total variance in suicide behavior. (b) The indirect association between uncertainty stress and suicide behavior was moderated by family relationship. Specifically, the paths from uncertainty stress to depressive symptoms (interact effect = -0.06, P<0.001) and depressive symptoms to suicide behavior (interact effect = -0.08, P<0.01) were weakened in the context of higher family relationship. Conclusion Depressive symptoms play a crucial role in bridging uncertainty stress and suicide behavior, while the family relationship can buffer the mediation impact of depressive symptoms. These findings significantly contribute to the prevention and intervention of suicide in Chinese university students.

Suicide risk communication and intervention preferences for veterans and service members. Front Public Health 2023; 11:1215925. [PMID: 38074746 PMCID: PMC10703287 DOI: 10.3389/fpubh.2023.1215925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 11/01/2023] [Indexed: 12/18/2023] Open
Abstract
Despite the investment of public resources to fight staggering suicide rates among veterans, we know little about how veterans and service members in crisis communicate suicidal ideations, and what interventions they are willing to receive. We aim to identify communication and suicide intervention preferences of veterans and service members in times of crisis. Descriptive statistics were used to explore veterans communication of suicidal ideations. While 89.9% of participants indicated they were willing to speak to someone when having thoughts of suicide, less than 26% of participants indicated they were willing to bring up their thoughts with a crisis line or veterans organization. Rather, they indicate that family members (62.2%) and military friends (51.1%) would be their primary outreach. Logistic regression was used to determine whether or not preferred interventions varied by participant demographic characteristics. While the majority of participants indicated they were willing to allow intervention (88.6%), no one method was accepted by the majority of the population. The most accepted means of communication was to proactively contact a friend or family member about general life struggles (32.6%) or suicide-specific concerns (27.5%). Many participants were open to receiving resources (42.0%), suicide-specific mental health treatment (36.3%), and some sort of lethal means safety intervention (19.1%-26.4%). The age, marital status, and veterans status of participants significantly impacted what interventions they were willing to allow. We discuss the implications of these findings and the need for evidence-based, multimodal interventions in order to assist veterans in need.

The Association Between Family Physical Abuse and Suicide Attempts Among Gender Minority Adolescents: A Comparison Study. LGBT Health 2023; 10:99-108. [PMID: 36106997 PMCID: PMC9986013 DOI: 10.1089/lgbt.2021.0415] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
Purpose: This study examines the prevalence of reported family physical abuse and the concurrent association between abuse and suicide attempts by adolescent gender identity. Methods: This study used the Profiles of Student Life: Attitudes and Behaviors dataset (N = 121,150 adolescents aged 11-19 [mean = 14.74, standard deviation = 1.78]) collected from 61 participating school districts and programs across the United States by Search Institute from 2012 to 2015. Multigroup logistic regression was used to examine the association between family abuse and suicide attempts by gender identity. Correlates included race/ethnicity, age, parent education, rurality, binge drinking, and tobacco use. Results: Results indicated that cisgender adolescents (i.e., participants who did not select a transgender identity) reported significantly less family abuse compared to gender minority adolescents. Family physical abuse was associated with higher odds of suicide attempts among all adolescents. The association was stronger for female adolescents compared to male adolescents but not significantly different across gender minority adolescents, including those who identify as transgender female to male, transgender male to female, and transgender without identifying or being unsure of their gender identity. The association between family physical abuse and suicide attempts was stronger among heterosexual female adolescents compared to sexual minority female, heterosexual male, sexual minority male, heterosexual gender minority, or sexual and gender minority adolescents. Conclusions: Findings highlight the importance of identifying and treating family abuse to prevent suicide attempts, particularly among gender and sexual minority adolescents.

Abstract
Suicide and suicide attempt affect a considerable part of the general population, and in spite of their prevalence, the stigma associated with suicide remains an unsolved problem surrounding this important public health problem, especially in lower-income countries such as Iran. Evidence shows that help-seeking from formal mental health services for suicidal people is low in countries like Iran. Previous studies on Iranian survivors of suicide attempts have shown that these people experience fear of stigma due to labels such as loss of faith in God, having forms of severe mental illnesses ("madness"), and being involved in unaccepted sexual relationships. The associated stigma prevents them from seeking appropriate health and social services. Although both self-stigma and public stigma contribute to an unwillingness to seek mental health care and suicide prevention efforts in Iran, public stigma may be of greater consequence, significantly impeding an individual's likelihood of accessing care for their suicidal thoughts or attempts. In such circumstances, many people with suicidal thoughts miss out on social and formal support programs offered by social and healthcare providers. In this perspective article, focusing on the public stigma regarding suicide in Iranian society, we address the challenges and barriers to seeking suicide prevention efforts in Iran and discuss culturally appropriate strategies to improve the current situation.

Predictors of Suicide Re-Attempt in a Spanish Adolescent Population after 12 Months' Follow-Up. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19137566. [PMID: 35805225 PMCID: PMC9265348 DOI: 10.3390/ijerph19137566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 06/17/2022] [Accepted: 06/18/2022] [Indexed: 01/27/2023]
Abstract
Background: This study aims to identify the main predictive factors that allow for the recognition of adolescents with a higher risk of re-attempting suicide. Method: A longitudinal 12-month follow-up design was carried out in a sample of 533 Spanish adolescents between 12 and 17 years old. The data collection period comprised September 2013 to November 2016, including a one-year follow-up after hospital discharge. Results: A statistically significant regression model was obtained to predict suicide re-attempt at 12-months’ follow-up (χ2 = 34.843; p < 0.001; Nagelkerke R2 = 0.105), including personal history of self-injury (OR = 2.721, p < 0.001, 95% CI [1.706, 4.340]) and age (OR = 0.541, p = 0.009, 95% CI [0.340, 0.860]), correctly classifying 82.6% of the sample. Our results show that having a personal history of self-injury and being younger than 14 years old were predictors of suicide re-attempt during the first year after an adolescent’s first admission to emergency services. Conclusions: Considering these factors could contribute to the design of more tailored and effective interventions to prevent suicidal behavior in adolescents at high risk of re-attempting suicide.

Trajectories of Suicidal Thoughts and Behaviors From Preschool Through Late Adolescence. J Am Acad Child Adolesc Psychiatry 2022; 61:676-685.

Abstract
OBJECTIVE Suicidal thoughts and behaviors (STBs) represent a significant and escalating public health concern in youth. Evidence that STBs can emerge in the preschool years suggests that some pathways leading to clinically significant STBs begin early in life. METHOD This prospective longitudinal study examined the developmental trajectories of STBs in children from ages 3 to 17, oversampled for preschool-onset depression. RESULTS Three unique trajectories of STBs across childhood and adolescence were identified: low class (n = 273) characterized by low rates of STBs, early-persistent class (n = 21) characterized by steadily increasing STBs, and late-onset class (n = 21) characterized by low rates of STBs through age 10 followed by a dramatic increase from ages 11 to 14 years. Preschool measures of depression symptoms, externalizing symptoms, impulsivity, and lower income relative to needs were associated with both high-risk STB classes. Both high-risk STB classes reported greater functional impairment, more externalizing symptoms, and more cumulative stressful life events in adolescence relative to the low class; the late-onset class also reported poorer academic functioning relative to both the early-persistent and low classes. CONCLUSION A significant minority of this prospectively followed group of preschool children evidenced STBs by and/or after age 10. Although relatively rare before age 10, approximately half of the children who experienced STBs in adolescence first exhibited STBs in early childhood and comprised a trajectory suggesting increasing STBs. In contrast, approximately half of children first exhibited STBs in early adolescence. Early screening and identification of at-risk youth during both preschool and late childhood is important for early intervention regarding STBs.

Abstract
OBJECTIVE During the past decade, the pediatric suicide rate has nearly tripled. Yet, little is known about suicide behavior (SB) in children. Identification of risk factors associated with SB during childhood may be critical to preventing future attempts. The purpose of this study was to examine the relationship between neurocognitive performance and suicide ideation (SI) in children. METHOD The present study utilized baseline data from 11,875 participants in the Adolescent Brain Cognitive Development (ABCD) study, a longitudinal study that follows 9- and 10-year-old children through late adolescence to examine factors that influence developmental trajectories. Suicidality was assessed by the Kiddie Schedule for Affective Disorder and Schizophrenia (KSADS) suicide module completed by the parent. Neurocognitive ability was assessed using the NIH Toolbox Cognition measures administered to the youth. RESULTS Children with a history of SI reported by their parent or concordant parent and youth report of SI demonstrated lower performance on the NIH Toolbox Picture Sequence Memory Test compared to children without SI. The difference in performance on the memory task remained significant when including demographic characteristics, family history of suicide, and internalizing symptoms in the model as covariates. CONCLUSIONS To our knowledge, this is the first study to identify decreased episodic memory in children with SI. These findings are similar to results from adult and adolescent studies which have reported decreased memory performance among suicide attempters. Deficits in episodic memory may impact a child's ability to problem-solve and generate potential future outcomes, which may increase the risk for SB. Early identification of memory deficits in children may inform suicide prevention and intervention efforts.Highlights6% of parents and children reported a history of active suicide ideation in children.Children with a history of suicide ideation had lower episodic memory performance.Early identification of memory deficits may inform suicide intervention efforts.

Abstract
OBJECTIVE Most assessments of suicidal ideation and behavior (SIB) are limited by reliance on a single assessor, typically a clinician or patient, with scant detail on patient-related drivers of SIB and inability to detect rapid change in SIB. Furthermore, many techniques do not include a semistructured interview, increasing rater variability. The Suicide Ideation and Behavior Assessment Tool (SIBAT) addresses these limitations. DESIGN More than 30 experts in scale development, statistics, and clinical management of suicidal patients collaborated over a greater than four-year period to develop the SIBAT. Input for content and validity was received from patients, clinicians, and regulatory authorities in the United States (US) and Europe. Psychometric properties of the SIBAT were evaluated in validation studies. RESULTS The SIBAT is organized into eight independent patient- or clinician-rated modules with branching logic and scoring algorithms, which necessitates computerization. Patient-reported information is first captured in Modules 1 to 5. Thereafter, an experienced clinician reviews the patient's report, conducts a semistructured interview (Module 6), and assesses the patient's suicide risk (Module 7) and optimal antisuicide management (Module 8). Input from cognitive interviews of diverse adult, adolescent, and clinician participants was incorporated into the final version of the SIBAT. Psychometric testing demonstrated good inter-rater reliability (intraclass coefficient range: 0.68-0.82), intra-rater reliability (weighted-kappa range: 0.64-0.76), and concurrent validity with other instruments for assessing SIB. CONCLUSION Patient- and clinician-based assessments and the psychometric studies summarized in this report support the validity and reliability of the SIBAT for capturing critical information related to assessment of SIB in adolescents and adults at risk for suicide.

Abstract
BACKGROUND Abnormalities in the hypothalamic-pituitary-adrenal axis (HPA) have been reported in individuals with suicide behavior. The aim of the study was to evaluate cortisol levels in peripheral plasma of individuals with more than one suicide attempt. METHODS Cortisol concentrations in peripheral plasma were measured using the ELISA technique. Suicide attempts were evaluated by the Columbia Suicide Severity Rating Scale, while depression was evaluated by the Hamilton Depression Rating Scale. RESULTS We found elevated cortisol levels in the suicide attempt group when compared with healthy controls (F = 7.26, p-value = 0.008), but no statistical differences with the psychiatric diseases group (F = 1.49, p-value = 0.22). Cortisol levels were higher in individuals with depression (F = 8.99, P = 0.004) and in individuals with two or more suicide attempts (F = 13.56, P < 0.001). CONCLUSIONS Cortisol levels are increased in individuals who attempt suicide and higher of cortisol concentrations in plasma regard to depression and more attempts of suicide.

Abstract
OBJECTIVES We aimed to examine the association of TPH1 polymorphisms with the risk of suicide behavior (SB). DESIGN Systematic review and meta-analysis. METHOD All relevant studies that evaluated the association between the A218C (rs1800532), A779C (rs1799913) and A6526G (rs4537731) polymorphisms and the susceptibility to SB published up to September 2021 were identified through a comprehensive systematic search in PubMed, Scopus, EBSCO and Science Direct electronic databases. The association between TPH1 gene polymorphisms and SB was evaluated using inherence models by odds ratio (OR) and 95% confidence interval (CI). Subgroup analyses, heterogeneity analyses, and publication bias were also tested in this meta-analysis. RESULTS The meta-analysis for TPH1 A218C revealed an increased risk of SB in the dominant model (OR = 1.11, 95%CI 1.01-1.22). We also observed a positive association in the allelic (OR = 1.13, 95%CI 1.05-1.21), homozygous (OR = 1.22, 95%CI 1.06-1.40), heterozygous (OR = 1.21, 95%CI 1.08-1.37) and dominant (OR = 1.21, 95%CI 1.09-1.34) inherence models with the suicide attempt. Additionally, in the heterozygous (OR = 0.84, 95%CI 0.73-0.97) and dominant (OR = 0.79, 95%CI 0.68-0.91) inherence models we detected an association with completed suicide. Based on ethnicity, an association of SB in the European population also was observed (OR = 1.29, 95%CI 1.12-1.51). However, for both A779C and A6526G polymorphisms we did not find evidence of an association with SB. CONCLUSION This meta-analysis suggests that the A218C polymorphism of TPH1 gene could be a possible risk factor of SB. Future large-scale studies are required to analyze the molecular mechanisms by which affect the susceptibility of developing suicide behavior.

Abstract
INTRODUCTION Suicide thoughts and behavior (STB) are associated with premature mortality and is disproportionately represented among those with opioid use disorder (OUD). Recent trends in STB among those with OUD are lacking. We investigated trends in STB among US adults with versus without OUD using six waves of cross-sectional, nationally-representative, epidemiological data. METHODS Data came from the 2015-2020 National Survey on Drug Use and Health (combined n = 241,675). We compared past-year STB outcomes (i.e., thoughts of seriously considering killing self (SI), suicide plan (SP), suicide attempt (SA)) among adults with versus without past-year OUD. Unadjusted and adjusted logistic regression tested the association between survey-year and past-year STB outcomes (i.e., SI, SP/SA) stratified by OUD status. RESULTS Between 2015 and 2020, 26% versus 4% of those with and without OUD, respectively, reported SI, 10% versus 1% reported a SP, and 6% versus 1% reported SA (all ps < 0.001). In adjusted analyses, across survey years, no changes in the prevalence of SI were observed for adults with or without OUD, and no changes were observed over time for SP/SA in adults with or without OUD. OUD severity and treatment status did not moderate the relationship between OUD and STB outcomes. CONCLUSIONS Among US adults, OUD was associated with thoughts of suicide and suicide behavior. The heightened prevalence of STB in adults with OUD has not changed in recent years. Screening for SI is needed among those reporting opioid misuse and should be routinely integrated into OUD prevention and treatment.

Abstract
OBJECTIVES Childhood trauma might be a modifiable risk factor among adults with serious mental illness. However, the correlation of child trauma and suicide is unclear, which were cited most frequently as the biggest challenge to schizophrenia (SCZ) patients in China. We aim to study relationships between child trauma and suicide in SCZ patients of different disease stages. METHODS Ninety-one participants were included and divided into two groups, namely, first-episode group (n = 46), relapsed group (n = 45). The Positive and Negative Syndrome Scale was used to evaluate the severity of psychotic symptoms. The Beck's Suicide Intent Scale and The Nurses' Global Assessment of Suicide Risk were conducted by patient self-report to assess suicide symptom. The childhood trauma questionnaire was used to estimate severity of traumatic stress experienced during childhood. RESULTS Childhood trauma and different dimensions of suicide were significantly higher in the relapsed group than first-episode group (P < 0.01, respectively). BMI has a significant positive relationship with recent psychosocial stress (β = 0.473, t = 3.521, P < 0.001) in first-episode group. As in relapsed group, BMI has a positive effect between severe mental illness and suicide ideation (β = 0.672, t = 5.949, P < 0.001; β = 0.909, t = 2.463, P < 0.001), Furthermore, emotional neglect presented positively related to the suicide risk and proneness to suicidal behavior (β = 0.618, t = 5.518, P < 0.001; β = 0.809, t = 5.356, P < 0.001). CONCLUSION Relapsed group of patients had significantly more severe childhood trauma, recent psychosocial stress, suicidal risk and proneness to suicidal behavior. BMI and emotional neglect are unique predictors for different dimensions of suicide.

Abstract
Although some progress has been made in the molecular biological detection of major depression disorder (MDD), its specificity and accuracy are still insufficient. This study is aimed to find hub genes, which could contribute to MDD related suicide and provide potential therapeutic targets for diagnosis and treatment. We downloaded RNA expression and clinical information from Gene Expression Omnibus (GEO) Dataset. Then, weighted gene co-expression network analysis (WGCNA) was applied to find core modules. Logistic regression was performed to identify the independent risk factors, and a scoring system was constructed based on these independent risk factors. As a result, a total of 16487 genes were selected to further conducted WGCNA analysis. We found that tan and green functional modules were exhibited high correlation with suicide behavior. 309 genes were identified in tan modules that were the strongest positively correlated with suicide behavior. Functional analysis in tan module indicated that activation of enzymes including nitric-oxide synthase and endoribonuclease, estrogen signaling pathway, glucagon signaling pathway, and legionellosis pathway were most enriched in MDD. Furthermore, we applied protein–protein interaction (PPI) analysis to select the hub genes and 10 genes were found in the core area of network. Then, we identified three-gene base independent risk signature by logistic regression model, including HSPA1A, RASEF, TBC1D8B. In conclusion, our study suggests that the tan module genes are closely related to suicide behaviors, which is mainly caused by multiple signaling pathway activation. The three-genes-based signature could provide a better efficacy to predict suicidal behavior in MDD patients.

Abstract
Background and objective Emergency physicians come across a myriad of medical afflictions resulting from suicide attempts. The Indian contribution to global suicide deaths is alarming; the social construct of India is unique, and so are the problems and challenges. This study aims to describe the social background, demographic parameters and correlate the clinical profile and outcomes of all patients presenting with an attempted or completed suicide. Materials and methods The present study is a hospital-based prospective observational study conducted by the Department of Emergency Medicine at RL Jalappa Hospital and Research Centre, a rural tertiary-care center in Karnataka, India, from June 2020 to February 2021. After stabilizing the patient, a detailed socio-demographic history was recorded. Details of the suicide attempt and findings of the clinical examination were noted. Results The final study sample consisted of 89 patients who presented to the emergency room (ER). Fifty-three patients were female, and thirty-six were males; the average age of the sample was 28.4 ± 11 years. A higher proportion of men who completed pre-university education (p= 0.0005, c2= 11.98) or had a graduate degree (p= 0.009, c2= 6.71) attempted suicide. Amongst all women who attempted suicide, 73.6% (n=39) were married at the time of the event (p= 0.0006, c2= 11.79). Poisoning (n=59) was the most common method of attempting suicide. We also observed that it was primarily men who attempted suicide when under the influence of alcohol (p= 0.006, c2= 7.57). The most common reason for attempting suicide was familial disharmony, including domestic violence. A Glasgow Coma Scale (GCS) score of 9/15 and less at the time of presentation resulted in a mortality rate of 28.6%, whereas patients with a GCS score of 10 and above had a mortality rate of 6.1% (p= 0.04, c2= 4.14). Discussion Marriage appears to be less protective for Indian women than Indian men. Poisoning was the most common method of attempted suicide in our study, followed by tablet overdose. The reason for the above could be ease of access to household poisons. Insecticides have been a preferred method in the Indian population over the years. Aluminum phosphide poisoning, a common constituent of rodenticides, is associated with a high mortality rate. However, in the West, firearm-related incidents have the highest mortality. Multiple correspondence analysis (MCA) of the National Crime Records Bureau (NCRB), India, data showed that adult males succumb majorly to romantic relations, unemployment, and failure in examinations. The use of alcohol was more in the illiterate and unskilled workers; however, high school educated persons and students used alcohol intentionally to facilitate suicide. Lower Glasgow Coma Scale values are associated with higher fatality; however, some studies found that Full Outline of Unresponsiveness (FOUR) and Acute Physiology and Chronic Health Evaluation Score (APACHE) II scores are better mortality indicators. Conclusion Besides the presentation and GCS score, cognizance of the lethality of different methods in attempting suicide provides clues in anticipating the patient's clinical course. The social patterns of suicide must be considered while designing awareness campaigns and focused outreach programs to decrease suicides. A strict policy must be made and enforced to limit the availability of household poisons.

Abstract
BACKGROUND Suicide among older adults is a multifactorial problem with several interrelated factors involved that vary with age, gender and culture. The number of suicides is highest in those aged 70 years or older in almost all regions of the world. With the increase in life expectancy, and the decrease in mortality due to other causes of death, we could expect the absolute number of older adults' suicide continue increasing. METHODS Review of the literature on suicide protective factors of suicide among older adults. RESULTS Improvements on social determinants of health and the timely detection and early treatment of affective disorders are key interventions. Prevention based on community actions and training of gatekeepers may have positive impact. Community programs that promote a sense of usefulness, belonging and that contribute to preserve social integration should be encouraged. Governments should develop the improvement of retirement programs and the development of support systems. The access to general health and mental health services should be facilitated and Primary Care professionals should receive proper training to detect and manage older persons at risk. Actively promoting a culture of coping to different stages of life and to the changes imposed by the advancing of age should form the essential part of a process bringing to better successful aging avenues. CONCLUSIONS Suicide prevention in older adults should broaden its focus and pay attention to the many socio-environmental conditions that may be relevant in older age, especially social isolation, financial security and physical health.

Abstract
Objectives To determine the demographic predictors of suicidal behaviors and measure the association between the spectrum of substance use disorders (SUD) and hospitalization for suicidal behaviors in the adolescent population. Methods We conducted a cross-sectional study using the nationwide inpatient sample and included 466,244 adolescent inpatients with psychiatric illnesses. The study sample was sub-grouped into suicidal (N = 182,454) and non-suicidal (N = 283,790) cohorts. The odds ratio (OR) of association for demographic characteristics and comorbid SUD in the suicidal group was evaluated using a logistic regression model witha P-value < 0.01. Results Our study population included 466,244 adolescent inpatients. Females had higher odds of suicidal behaviors (OR 1.45; 95% CI 1.431-1.470) compared to males. The most prevalent comorbid SUD among suicidal inpatients was cannabis (15.3%) but had a statistically non-significant association with suicidal behaviors (OR 0.98; 95% CI 0.95-0.99). Inpatients with alcohol use disorders had significantly increased odds of association with suicidal behaviors (OR 1.18; CI: 1.142-1.209) compare to other SUD. Among other substances (cannabis and stimulants), there existed a statistically non-significant association with hospitalization for suicidal behaviors. Conclusion Adolescent inpatients with comorbid alcohol use disorders were at 18% higher odds of hospitalization for suicidal behaviors. Our study provides a basis for more research while also suggesting potential avenues for early identification and intervention efforts for comorbid SUD in adolescents requiring psychiatric care to improve their prognosis and quality of life.

Abstract
INTRODUCTION Mindfulness-based interventions (MBI) have been growing progressively as treatment options in the field of mental health. Aim: To assess the impact of mindfulness-based interventions for reducing suicidal thoughts and behaviors. METHODS A systematic review was performed in December 2020 using PubMed, PsycINFO, EMBASE, SciELO, Pepsic, and LILACS databases with no year restrictions. The search strategy included the terms ('mindfulness' OR 'mindfulness-based') AND ('suicide' OR 'suicidal' OR 'suicide risk' OR 'suicide attempt' OR 'suicide ideation' OR 'suicide behavior'). The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO), CRD42020219514. RESULTS A total of 14 studies met all inclusion criteria and were included in this review. Most of the studies presented Mindfulness-Based Cognitive Therapy as the MBI assessed (n=10). An emerging and rapidly growing literature on MBI presents promising results in reduction of suicide risk, particularly in patients with MDD. Four studies assessing other MBI treatment protocols (Mindfulness-Based Stress Reduction; Daily Mindfulness Meditation Practice; Mind Body Awareness and Mindfulness-Based Cognitive Behavior Therapy) all demonstrated that MBI reduces factors associated with suicide risk. CONCLUSION MBI might target specific processes and contribute to suicide risk reduction.

Abstract
The aim of the present study was to evaluate whether anxiety and insomnia symptoms, somatic symptoms, and social dysfunction mediate the link between chronotype and suicidality, as depressive symptoms are known to do, among students of the faculties of Medicine and Psychology. Data from a total of 289 students were eligible for the analysis. The students completed the Suicide Behaviors Questionnaire - Revised, Composite Scale of Morningness, General Health Questionnaire. Single-predictor linear regression models were created to predict suicidality, with a subsequent mediation analysis. A preference toward eveningness was associated with an increase in suicidality Somatic symptoms, anxiety/insomnia, and depressive symptoms fully mediated the relationship between chronotype and suicidality. Depressive symptoms were found to present the strongest effect size of mediation. Social dysfunction was associated with both eveningness and suicidality, but did not play a mediating role. There might be a need to evaluate nonpsychotic mental health indices other than depressive symptoms when assessing the link between suicidality and chronotype among students of the faculties of Medicine and Psychology.

Abstract
The psychometric properties of the Suicide Ideation and Behavior Assessment Tool (SIBAT) were evaluated in 130 participants with varying levels of suicidality. Inter- and intra-rater reliability were assessed for clinician-rated outcomes, including the revised Clinical Global Impressions (CGI) of severity of suicidality (CGI-SS-r). Concurrent validity of patient-reported modules with Patient-reported Outcomes Measurement Information System (PROMIS) depression scale and Sheehan-Suicidality Tracking Scale Clinically Meaningful Change Measure (S-STS CMCM), and concordance between Columbia Classification Algorithm of Suicide Assessment (C-CASA) mappings for SIBAT, S-STS CMCM and Columbia-Suicide Severity Rating Scale (C-SSRS) were assessed. 52/130 participants (mean [SD] age: 38.3 [17.77] years) consented for multiple interviews (C-CASA mappings: n=52; rater-reliability: n=25/52). SIBAT demonstrated good intra-rater reliability (weighted-kappa range:0.64-0.76; CGI-SS-r, 0.75) and adequate inter-rater reliability (ICC range:0.68-0.82; CGI-SS-r, 0.81). There were strong correlations between PROMIS depression scores and SIBAT Module 5 ratings (Spearman correlations, r=0.64-0.74) and moderate correlations (r=0.29-0.72) between S-STS CMCM and SIBAT Modules 2, 3 and 5 ratings. Moderate agreement was noted between SIBAT C-CASA mappings and corresponding mappings from S-STS CMCM (weighted kappa: 0.54) and C-SSRS (weighted kappa: 0.56). Thus, the SIBAT provided valid assessment of suicidal ideation and behavior that could be reliably rated and adequately mapped to the C-CASA.

The Role of Demoralization and Meaning in Life (DEMIL) in Influencing Suicidal Ideation Among Patients Affected by Chronic Pain: Protocol of a Single-Center, Observational, Case-Control Study. JMIR Res Protoc 2020; 9:e24882. [PMID: 33144275 PMCID: PMC7728536 DOI: 10.2196/24882] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 11/03/2020] [Accepted: 11/03/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Chronic pain is a significant risk factor for suicidal ideation (SI) and suicidal behavior (SB), including a 20%-40% prevalence rate of SI, a prevalence between 5% and 14% of suicide attempts, and a doubled risk of death by suicide in patients with chronic pain compared to controls. In most studies, associations between chronic pain and suicidality are robust, even after adjusting for the effect of sociodemographics and psychiatric comorbidity, and particularly for depressive conditions. A number of specific conditions that can modulate suicidality risk in patients with chronic pain have been investigated, but there is a need for their more specific characterization. Numerous recent studies have shown that demoralization and meaning in life (MiL) constructs affect suicidality as risk and protective factors, respectively. These constructs have been mainly investigated in patients with somatic illness and in community-dwelling individuals who may present with SI or SB independently of a psychiatric diagnosis of depression. However, a paucity of studies investigated them in suicidal patients affected by chronic pain. OBJECTIVE The primary objective of this project is to investigate the relationship between demoralization and MiL on SI risk in patients with chronic pain. The secondary objectives are (1) to test whether demoralization can occur independently of depression in patients with chronic pain and SI, (2) to examine whether the expected association between demoralization and SI may be explained by a sole dimension of demoralization: hopelessness, (3) to examine whether the presence of MiL, but not the search for MiL, is associated with less SI, and (4) to explore whether previously described MiL profiles (ie, high presence-high search, high presence-low search, moderate presence-moderate search, low presence-low search, and low presence-high search) emerge in our cohort. METHODS This project is a single-center, observational, case-control study-the Demoralization and Meaning in Life (DEMiL) study-conducted by the Division of Clinical Pharmacology and Toxicology, the Multidisciplinary Pain Centre, and the Service of Liaison Psychiatry and Crisis Intervention at the Geneva University Hospitals. Self- and hetero-administered questionnaires were conducted among patients and controls, matched by age and gender. The Ethics Committee of the Canton of Geneva approved the scientific utilization of collected data (project No. 2017-02138; decision dated January 25, 2018). Data have been analyzed with SPSS, version 23.0, software (IBM Corp). RESULTS From March 1, 2018, to November 30, 2019, 70 patients and 70 controls were enrolled. Statistical analyses are still in progress and are expected to be finalized in November 2020. To date, we did not observe any unfavorable event for which a causal relationship with the collection of health-related personal data could be ruled out. Results of this study are expected to form the basis for possible prevention and psychotherapeutic interventions oriented toward demoralization and MiL constructs for suicidal patients with chronic pain. CONCLUSIONS The interest in exploring demoralization and MiL in chronic pain patients with SI arises from the common clinical observation that experiencing chronic pain often requires a revision of one's life goals and expectations. Hence, the impact of chronic pain is not limited to patients' biopsychosocial functioning, but it affects the existential domain as well. The major clinical implications in suicidal patients with chronic pain consist in trying to (1) delineate a more precise and individualized suicide risk profile, (2) improve detection and prevention strategies by investigating SI also in individuals who do not present with a clinically diagnosed depression, and (3) enhance the panel of interventions by broadening supportive or psychotherapeutic actions, taking into consideration the existential condition of a person who suffers and strives to deal with his or her suffering.

Abstract
This study described the prevalence of suicidal behaviors and depression among adolescents in Hanoi, Vietnam, and examines the associated factors. In 2019, a school-based survey was conducted in three high schools in Hanoi and 661 high students were included into the study. We found that the prevalence of 12-month suicidal thoughts, suicide plans, and suicide attempts were 14.2%, 5.5%, and 3.0% respectively. Notably, the depression score mean was 16.1±4.9, among major predictors of suicidal ideation. Therefore, developing psychological care services in school is imperative to the early detection of mental disorders and the prevention of suicidal behaviors for the students.

Abstract
In recent years, suicidal behaviors have shown substantial increase worldwide. This trend is also prominent in Israel and has led to a dramatic increase in mental health treatment demand resulting in long wait times and low treatment acceptance rate. To address the critical need in crisis intervention for children and adolescents at suicidal risk we developed an ultra-brief acute crisis intervention, based on Interpersonal Psychotherapy (IPT). IPT is an evidence-based intervention for various psychopathologies among different age groups. The current adaptation of IPT-A is comprised of five weekly sessions, followed by monthly follow-up caring email contacts to the patients and their parents, over a period of 3 months. This paper aims to review the theoretical foundation of this intervention, describe the research design, and present preliminary results of a pilot study. Preliminary Results from our samples of 26 adolescents indicate meaningful trends for both the suicidal ideation (SIQ) and depression (MFQ) outcome measures. Significant interaction was found concerning suicidal ideation but not for depression. Main limitations include small sample size and stratified controls. The treatment appears to be safe, feasible and acceptable and initial results show promising trends to support further study of the approach.

Abstract
The association between trauma and psychosis outcomes is well-established, and yet the impact of trauma on comorbid clinical symptoms-such as aggression, non-suicidal self-injury behavior (NSSIB), suicide ideation, and suicide behavior-for those with psychosis is unclear. To effectively treat those with first-episode psychosis (FEP) and a history of trauma, we need to understand the impact of trauma on their whole presentation. FEP participants were recruited from an Early Psychosis Program (N = 187, ages 12-35, 72.2% male). Clinicians gathered history of trauma, aggression, and suicide data, and rated current symptom severity and functioning. Data was coded using clinician rated measures, self-report measures, and retrospective clinical chart review. Regression analyses examined whether trauma was associated with a history of aggression, suicidal ideation, suicide behavior, NSSIB, symptoms, and functioning. Trauma was associated with aggression, aggression severity and type of aggression (aggression towards others). Trauma was also associated with depression severity, suicide ideation, most severe suicide ideation, and NSSIB. Trauma was not associated with suicide behavior, severity of suicide behavior or psychosocial functioning. Integrating trauma treatment into FEP care could reduce rates of depression, aggression, suicide ideation, and NSSIB for those with a history of trauma. To reduce suicide attempt occurrence and improve functioning, more research is needed.

Abstract
PURPOSE There is growing evidence showing that inflammatory cytokines and neuropeptides may be involved in the pathophysiology of suicidal behavior. However, studies have yielded contradictory data, and no biological markers that help predict suicide have been identified. This study aimed to identify biological patterns, such as NPY, IL-1β and hypocretin plasma levels, in people who died by suicide. PATIENTS AND METHODS Twenty-two people who died by suicide compared with 22 controls matched for age and sex were studied. In suicide and control subjects, we estimated the levels of NPY, IL-1β and hypocretin in plasma using enzyme-linked immunosorbent assay. The data are presented as the median (25th-75th percentile). RESULTS We found (1) a significant elevation in plasma NPY levels in suicide subjects versus control subjects (suicide: 11.38 (9.380-16.55); controls: 8.95 (7.590-10.93); P=0.013), and plasma NPY concentrations were approximately 62% higher in suicide subjects than those in control subjects; (2) a significant decrease in plasma IL-1β concentrations between suicide and control subjects (suicide: 121.1 (82.97-143.0); controls: 425.9 (233.1-835.3); P<0.001) as well as a decrease in IL-1β concentrations by almost 80%; and (3) no significant difference in plasma hypocretin levels between suicide and control subjects (suicide: 16.62 (13.62-25.77); controls: 21.63 (14.97-29.72); P=0.356). CONCLUSION Our results suggest that plasma NPY and IL-1β were related with suicide behavior rather than to suicide causes or suicide method. Specific combinations of plasma biomarkers may discriminate between types of suicidal behaviors and indicate increased risk for future suicide attempts.

Abstract
Suicide takes the lives of nearly a million people each year and it is a tremendous economic burden globally. One important type of suicide risk factor is psychiatric stress. Prior studies mainly use survey data to investigate the association between suicide and stressors. Very few studies have investigated stressor data in electronic health records, mostly due to the data being recorded in narrative text. This study takes the initiative to automatically extract and classify psychiatric stressors from clinical text using natural language processing-based methods. Suicidal behaviors were also identified by keywords. Then, a statistical association analysis between suicide ideations/attempts and stressors extracted from a clinical corpus is conducted. Experimental results show that our natural language processing method could recognize stressor entities with an F-measure of 89.01 percent. Mentions of suicidal behaviors were identified with an F-measure of 97.3 percent. The top three significant stressors associated with suicide are health, pressure, and death, which are similar to previous studies. This study demonstrates the feasibility of using natural language processing approaches to unlock information from psychiatric notes in electronic health record, to facilitate large-scale studies about associations between suicide and psychiatric stressors.

Abstract
BACKGROUND Studies of the relationship between bullying and suicide behavior yield mixed results. AIMS This is the first study comparing frequencies of suicide behavior in four bullying groups (bully, victim, bully/victim, and neither) in two large psychiatric and community samples of young children and adolescents. METHOD Maternal ratings of bullying and suicide ideation and attempts were analyzed for 1,291 children with psychiatric disorders and 658 children in the general population 6-18 years old. RESULTS For both the psychiatric and community samples, suicide ideation and attempt scores for bully/victims were significantly higher than for victims only and for neither bullies nor victims. Differences between victims only and neither victims nor bullies were nonsignificant. Controlling for sadness and conduct problems, suicide behavior did not differ between the four bullying groups. All children with suicide attempts had a comorbid psychiatric disorder, as did all but two children with suicide ideation. CONCLUSION Although the contribution of bullying per se to suicide behavior independent of sadness and conduct problems is small, bullying has obvious negative psychological consequences that make intervention imperative. Interventions need to focus on the psychopathology associated with being a victim and/or perpetrator of bullying in order to reduce suicide behavior.
