Suicide Attempt as a Risk Factor for Completed Suicide: Even More Lethal Than We Knew

Association between cognitive functioning, suicidal ideation and suicide attempts in major depressive disorder, bipolar disorder, schizophrenia and related disorders: A systematic review and meta-analysis

INTRODUCTION

Treatable mental disorders, such as psychotic, major depressive disorder (MDD), and bipolar disorder (BD), contribute to a substantial portion of suicide risk, often accompanied by neurocognitive deficits. We report the association between cognitive function and suicidal ideation/suicide attempts (SI/SA) in individuals with schizoaffective disorder, BD, and MDD.

METHODS

A systematic search was conducted on PubMed, Ovid and Scopus databases for primary studies published from inception to April 2024. Eligible articles that reported on the effect size of association between cognition and SI/SA were pooled using a random effects model.

RESULTS

A total of 41 studies were included for analysis. There was a negative association between executive functioning and SI/SA in schizoaffective disorder (SA: Corr = -0·78, 95 % CI [-1·00, 0·98]; SI: Corr = -0·06, 95 % CI [-0·85, 0·82]) and MDD (SA: Corr = -0·227, 95 % CI [-0·419, -0·017]; SI: Corr = -0·14, 95 % CI [-0·33, 0·06]). Results were mixed for BD, with a significant positive association between SA and global executive functioning (Corr = 0·08, 95 % CI [0·01, 0·15]) and negative association with emotion inhibition. Mixed results were observed for processing speed, attention, and learning and memory, transdiagnostically.

LIMITATIONS

There is heterogeneity across sample compositions and cognitive measures. We did not have detailed information on individuals with respect to demographics and comorbidities.

CONCLUSIONS

We observed a transdiagnostic association between measures of cognitive functions and aspects of suicidality. The interplay of cognitive disturbances, particularly in reward-based functioning, may underlie suicidality in individuals with mental disorders. Disturbances in impulse control, planning, and working memory may contribute to self-injurious behavior and suicide.

The association of school bullying victimization and suicidal ideation among school-aged adolescents in Yixing City, China

BACKGROUND

Research on the associations of type-specific bullying victimization and poly-bullying victimization with suicidal ideation is limited and contradictory. This study aimed to examine these associations among school-aged adolescents.

METHODS

A total of 13,258 students from 3 middle schools and 4 high schools in a southern city in China completed a cross-sectional questionnaire in 2019. Multinomial logistic regressions were used to examine associations between type-specific bullying victimization and poly-victimization with suicidal ideation.

RESULTS

The latent class analysis identified three subgroups of suicidal ideation: low (70.0 %), moderate (24.0 %), and high (6.0 %). Compared with non-bullying victimization in the past year, the corresponding adjusted odds ratios [aOR] (95 % CI) of moderate and high suicidal ideation for only physical victimization were 1.74 (1.15, 2.63) and 2.51 (1.18, 5.38), respectively, for only relational victimization were 1.26 (0.97, 1.62) and 2.48 (1.65, 3.71), respectively, for only verbal victimization were 1.45 (1.17, 1.78) and 1.42 (0.90, 2.22), respectively, for only property victimization were 1.30 (1.03, 1.65) and 1.31 (0.80, 2.16), respectively, and for sexual victimization were 1.38 (1.03, 1.83) and 2.45 (1.50, 3.99), respectively. Poly-bullying victimization was associated with moderate (aORtwo = 1.45 (1.24, 1.70); aORthree = 1.70 (1.41, 2.05), aORfour = 2.03 (1.61, 2.58), aORfive = 2.48 (1.74, 3.53)) and high suicidal ideation (aORtwo = 2.01 (1.49, 2.70), aORthree = 3.87 (2.86, 5.25), aORfour = 4.55 (3.20,6.46), aORfive = 7.90 (5.06, 12.33)).

LIMITATIONS

The research design is cross-sectional, and relevant data was based on self-reports.

CONCLUSIONS

Different types of bullying victimization were associated with suicidal ideation and poly-bullying victimization and suicidal ideation association shows a dose-response-relationship.

Barriers and risk factors associated with non-treatment-seeking for suicidality onset during the COVID-19 pandemic among young adults

INTRODUCTION

Researchers predict long-term increases in suicide deaths following the COVID-19 pandemic. Little is known about risk factors for suicidal ideation (SI) and suicidal attempts (SA) or treatment barriers and promoters during the pandemic. We examine these factors in a young adult sample.

METHODS

Analyses used a 2022 cross-sectional survey dataset (N = 1,956). Logistic regression identified factors associated with pandemic suicidality (i.e., SI, SA). Non-treatment seekers reported barriers to seeking treatment. Logistic regression identified promotive factors associated with treatment-seeking.

RESULTS

28.6 % of our sample developed suicidality during the pandemic, of whom 49.6 % did not seek treatment. Asian race and sexual minority status were strongly associated with increased odds of pandemic suicidality. Among SI non-treatment-seekers, barriers were primarily attitudinal (e.g., "symptoms are not serious enough for treatment"); among non-treatment-seekers with SA, barriers were mostly structural (e.g., insufficient funds). Previous depression treatment was strongly associated with increased odds of treatment-seeking.

CONCLUSION

Asian American individuals were at increased risk for pandemic suicidality, which may reflect interpersonal risks related to COVID-19-related anti-Asian racism. Our findings point to a "foot-in-the-door" effect: past treatment-seeking was positively associated with future treatment-seeking. To promote this effect and decrease barriers, we suggest integrated mental health screening and referrals in primary care.

Neural responses to decision-making in suicide attempters with youth major depressive disorder

An improved understanding of the factors associated with suicidal attempts in youth suffering from depression is crucial for the identification and prevention of future suicide risk. However, there is limited understanding of how neural activity is modified during the process of decision-making. Our study aimed to investigate the neural responses in suicide attempters with major depressive disorder (MDD) during decision-making. Electroencephalography (EEG) was recorded from 79 individuals aged 16-25 with MDD, including 39 with past suicide attempts (SA group) and 40 without (NSA group), as well as from 40 age- and sex- matched healthy controls (HCs) during the Iowa Gambling Task (IGT). All participants completed diagnostic interviews, self-report questionnaires. Our study examined feedback processing by measuring the feedback-related negativity (FRN), ΔFN (FRN-loss minus FRN-gain), and the P300 as electrophysiological indicators of feedback evaluation. The SA group showed poorest IGT performance. SA group and NSA group, compared with HC group, exhibited specific deficits in decision-making (i.e., exhibited smaller (i.e., blunted) ΔFN). Post hoc analysis found that the SA group was the least sensitive to gains and the most sensitive to losses. In addition, we also found that the larger the value of ΔFN, the better the decision-making ability and the lower the impulsivity. Our study highlights the link between suicide attempts and impaired decision-making in individuals with major depressive disorder. These findings constitute an important step in gaining a better understanding of the specific reward-related abnormalities that could contribute to the young MDD patients with suicide attempts.

Pediatric suicide: Review of a preventable tragedy

Concepts of suicide are explored in this issue with a focus on suicide in children and adolescents. The epidemiology of pediatric suicide in the United States is reviewed; also, risk and protective factors, as well as prevention strategies, are discussed. Suicide in the pediatric athlete and the potential protective effect of exercise are examined. In addition, this analysis addresses the beneficial role of psychological management as well as current research on pharmacologic treatment and brain stimulation procedures as part of comprehensive pediatric suicide prevention. Though death by suicide in pediatric persons has been and remains a tragic phenomenon, there is much that clinicians, other healthcare professionals, and society itself can accomplish in the prevention of pediatric suicide as well as the management of suicidality in our children and adolescents.

Positive psychological functioning, resilience and styles of coping as buffers against suicidal behaviours. A case-control study

BACKGROUND

Studies in the literature mainly focus on understanding the risk factors for suicide, giving little relevance to protective variables. This study aimed at exploring the specific contribution of protective variables (resilience, coping and psychological well-being) in hospitalized suicide attempt (SA) makers.

METHODS

We recruited 50 inpatients who made a SA before admission and 50 inpatients with no history of SA matched for DSM-5 diagnosis, gender and age. Protective variables were evaluated with: Brief COPE questionnaire, Dispositional Resilience Scale (DRS-15), Psychological Well-Being Scale (PWB-18). Psychopathological features and symptom severity were assessed with: Global Assessment of Functioning Scale (GAF), Rapid Dimensional Assessment Scale (SVARAD), Brief Psychiatric Rating Scale (BPRS), Clinical Global Impressions (CGI), Hamilton Depression Rating Scale (HDRS17).

RESULTS

The DRS-15 total score was significantly lower in SA makers. SA makers displayed significantly lower scores on the Engagement and Cognitive Restructuring subscales of the Brief COPE. On the PWB-18, the Self-Acceptance subscale score was lower in SA makers.

LIMITATIONS

The small sample size suggests the need for caution in interpreting the results. Matching was carried out by excluding diagnoses of personality disorders.

CONCLUSIONS

Patients hospitalized following a SA are more often diagnosed with personality disorders, have deficit areas concerning resilience and coping, and lower psychological well-being compared to patients without a SA. When approaching a patient who has committed a SA, it may be useful to evaluate protective variables as well as risk factors, and encourage the development of adaptive coping mechanisms and positive self-evaluation through more dynamic therapeutic paths.

Suicide by Gunshot Wound to the Posterior Head and Neck: A Retrospective Case Series and Review of the Literature

ABSTRACT

Suicide by firearm is a significant public health concern in specific regions of the world. Depending on firearm availability, any type of firearm may be used, including handguns, shotguns, and long rifles. Common entrance wound sites in suicidal gunshot wounds include the head, with classic gunshot wound locations including the temple, the forehead, the submental aspect of the chin, and inside the mouth. Occasionally, suicidal gunshot wounds occur in atypical body locations such as the back of the head and neck. Given their relative rarity, suicidal gunshot wounds in these regions may be mistaken for homicides. In this report, we present 5 cases of suicidal gunshot wounds to the back of the head and/or neck. In our series, we focus on differentiating each case from homicides involving gunshot wounds in similar areas of the head and neck.

Remission, Recovery, Relapse, and Recurrence Rates for Suicide Attempts and Nonsuicidal Self-Injury for Suicidal Youth Treated With Dialectical Behavior Therapy or Supportive Therapy

OBJECTIVE

To evaluate rates of remission, recovery, relapse, and recurrence in suicidal youth who participated in a clinical trial comparing Dialectical Behavior Therapy (DBT) and Individual and Group Supportive Therapy (IGST).

METHOD

Participants were 173 youth, aged 12 to 18 years, with repetitive self-harm (including at least 1 prior suicide attempt [SA]) and elevated suicidal ideation (SI). Participants received 6 months of DBT or IGST and were followed for 6 months post-treatment. The sample was 95% female, 56.4% White, and 27.49% Latina. Remission was defined as absence of SA or nonsuicidal self-injury (NSSI) across one 3-month interval; recovery was defined across 2 or more consecutive intervals. Relapse and recurrence were defined as SA or NSSI following remission or recovery. Cross-tabulation with χ2 was used for between-group contrasts.

RESULTS

Over 70% of the sample reported remission of SA at each treatment and follow-up interval. There were significantly higher rates of remission and recovery and lower rates of relapse and recurrence for SA in DBT than for IGST. Across treatments and time points, SA had higher remission and recovery rates and lower relapse and recurrence rates than NSSI. There were no significant differences in NSSI remission between conditions; however, participants receiving DBT had significantly higher NSSI recovery rates than those receiving IGST for the 3- to 9-month, 3- to 12-month, and 6- to 12-month intervals.

CONCLUSION

Results showed higher percentages of SA remission and recovery for DBT as compared to IGST. NSSI was less likely to remit than SA.

PLAIN LANGUAGE SUMMARY

This study examined rates of remission, recovery, relapse, and recurrence of suicide attempts (SA) and nonsuicidal self-injury (NSSI) among the participants in the CARES Study, a randomized clinical trial of 6 months of Dialectical Behavior Therapy or Individual and Group Supportive Therapy. 173 youth aged 12 to 18 years participated in the study and were followed for 6 months post treatment. Over 70% of the sample reported remission of SA at each treatment and follow-up interval. There were significantly higher rates of remission and recovery and lower rates of relapse and recurrence for SA among participants who received Dialectical Behavioral Therapy. Across both treatments, remission and recovery rates were lower and relapse and recurrence rates were higher for NSSI than for SA. These results underscore the value of Dialectical Behavioral Therapy as a first line treatment for youth at high risk for suicide.

Digital phenotypes of real-time suicidal ideation: Correlates and consequences

INTRODUCTION

Suicidal ideation variability refers to within-day fluctuations in suicidal ideation, and has recently been proposed as an indicator of suicide risk. However, not much is known yet about its correlates and clinical relevance.

METHODS

We examined characteristics of real-time suicidal ideation using Ecological Momentary Assessment in 82 individuals with current active suicidal ideation. Data were collected four times daily over 21 days. Latent profile analysis was used to identify subtypes of suicidal ideation. We further examined sociodemographic and clinical correlates of the profiles, and their association with the occurrence of suicide attempts during a 1-year follow-up.

RESULTS

We identified three "digital" phenotypes of suicidal ideation that differed on the frequency, intensity and variability of ideation. The profiles were: high frequency, high intensity, moderate variability (Phenotype 1), moderate/high frequency, moderate intensity, high variability (Phenotype 2), and moderate frequency, low intensity, low variability (Phenotype 3). Phenotypes 1 and 2 were associated with a worse clinical profile at baseline (higher suicidal ideation and depressive symptom severity), and increased odds of suicide attempt during follow-up, compared to Phenotype 3. Phenotype 1 was further characterized by repeated suicidal behavior.

CONCLUSIONS

Two phenotypes of real-time suicidal ideation were identified that appear to confer a higher risk of suicidal behavior in the near future (12 months). These phenotypes were characterized by higher variability of suicidal ideation-and also higher intensity and frequency of ideation. Considering the small sample size, the clinical usefulness of the profiles remains to be demonstrated.

Characteristics Associated With Mental Health Treatment Prior to Suicide Among Youth in the United States

OBJECTIVE

To examine individual and contextual characteristics associated with receipt of mental health treatment prior to youth suicide.

METHOD

Data from the US National Violent Death Reporting System, Area Health Resource File, and Social Vulnerability Index were used to examine characteristics associated with receipt of mental health treatment within 2 months before death among youth suicide decedents aged 5 to 17 years from 2013 to 2020 (N = 6,229). The association between individual (demographic, precipitating circumstances, and clinical characteristics) and contextual-level variables (county health resources, Social Vulnerability Index) and mental health service use was modeled using logistic regression.

RESULTS

Mental health treatment was received by 31.6% of youth suicide decedents (n = 1,967) in the 2 months before suicide. Male individuals and youth from all racial and ethnic minority groups were less likely to receive mental health treatment in the 2 months prior to suicide, as were youth residing in non-metropolitan counties and living in counties characterized by high compared to low levels of social vulnerability. A history of family problems, a recent crisis, criminal/legal problems, and suicidal thoughts and attempts were associated with increased odds of receiving mental health services.

CONCLUSION

Youth suicide decedents who were male, members of a racial or ethnic minority group, and residing in counties that are non-metropolitan and/or socially disadvantaged were less likely to have received mental health services in the months prior to death. Suicide prevention efforts that focus on improving access to care are essential for these vulnerable populations at risk for suicide.

Individual suicide risk factors with resting-state brain functional connectivity patterns in bipolar disorder patients based on latent Dirichlet allocation model

BACKGROUND

The widespread problem of suicide and its severe burden in bipolar disorder (BD) necessitate the development of objective risk markers, aiming to enhance individual suicide risk prediction in BD.

METHODS

This study recruited 123 BD patients (61 patients with prior suicide attempted history (PSAs), 62 without (NSAs)) and 68 healthy controls (HEs). The Latent Dirichlet Allocation (LDA) model was used to decompose the resting state functional connectivity (RSFC) into multiple hyper/hypo-RSFC patterns. Thereafter, according to the quantitative results of individual heterogeneity over latent factor dimensions, the correlations were analyzed to test prediction ability.

RESULTS

Model constructed without introducing suicide-related labels yielded three latent factors with dissociable hyper/hypo-RSFC patterns. In the subsequent analysis, significant differences in the factor distributions of PSAs and NSAs showed biases on the default-mode network (DMN) hyper-RSFC factor (factor 3) and the salience network (SN) and central executive network (CEN) hyper-RSFC factor (factor 1), indicating predictive value. Correlation analysis of the individuals' expressions with their Nurses' Global Assessment of Suicide Risk (NGASR) revealed factor 3 positively correlated (r = 0.4180, p < 0.0001) and factor 1 negatively correlated (r = - 0.2492, p = 0.0055) with suicide risk. Therefore, it could be speculated that patterns more associated with suicide reflected hyper-connectivity in DMN and hypo-connectivity in SN, CEN.

CONCLUSIONS

This study provided individual suicide-associated risk factors that could reflect the abnormal RSFC patterns, and explored the suicide related brain mechanisms, which is expected to provide supports for clinical decision-making and timely screening and intervention for individuals at high risks of suicide.

National Trends in Emergency Department Visits for Suicide Attempts and Intentional Self-Harm

OBJECTIVE

This study estimated national annual trends and characteristics of emergency department visits for suicide attempts and intentional self-harm in the United States from 2011 to 2020.

METHODS

Data were from the National Hospital Ambulatory Medical Care Survey, an annual cross-sectional national sample survey of emergency departments. Visits for suicide attempts and intentional self-harm were identified using discharge diagnosis codes (ICD-9-CM for 2011-2015; ICD-10-CM for 2016-2020) or reason-for-visit codes. The annual proportion of emergency department visits for suicide attempts and intentional self-harm was estimated.

RESULTS

The weighted number of emergency department visits for suicide attempts and intentional self-harm increased from 1.43 million, or 0.6% of total emergency department visits, in 2011-2012 to 5.37 million, or 2.1% of total emergency department visits in 2019-2020 (average annual percent change, 19.5%, 95% CI=16.9, 22.2). Visits per capita increased from 261 to 871 visits per 100,000 persons (average annual percent change, 18.8%, 95% CI=17.6, 20.0). The increase in visits was widely distributed across sociodemographic groups. While suicide attempt and intentional self-harm visits were most common among adolescents, adults age 65 or older demonstrated the largest increase (average annual percent change, 30.2%, 95% CI=28.5, 32.0). Drug-related diagnoses were the most common co-occurring diagnosis among suicide attempt and intentional self-harm visits. Despite the rise in emergency department visits for suicide attempts and intentional self-harm, less than 16% included an evaluation by a mental health professional.

CONCLUSIONS

A significant national increase in emergency department visits for suicide attempts and intentional self-harm occurred from 2011 to 2020, as a proportion of total emergency department visits and as visits per capita. These trends underscore an urgent need to improve the continuum of mental health care for individuals with suicidal symptoms.

Perceived discrimination, mental health help-seeking attitudes, and suicide ideation, planning, and attempts among black young adults

BACKGROUND

Developing an understanding of the negative impact of discrimination is critical when examining the suicidality of Black young adults in the US. Suicide rates among Black young adults have increased at alarming rates. One of the reasons for this increase is the disparities related to access to mental health services, which has long-term health consequences. This study addresses a significant gap in the literature by examining associations between experiences of everyday discrimination, attitudes towards mental health help-seeking attitudes, on the outcomes suicide ideation, planning to die by suicide, and suicide attempts.

METHODS

The data came from a national study of the experiences of Black young adults regarding mental, physical, and sexual health. Participants were recruited from across the Midwestern region of the United States through Qualtrics Panels, an online survey delivery service used to recruit study participants. The total sample for this study was N = 362, and the average age of the sample was 21 (SD: 1.96). We used a logistic regression analysis to examine the role of everyday discrimination, mental health support-seeking attitudes, and covariates on the outcomes: suicide ideation, planning to die by committing suicide, and suicide attempts.

RESULTS

Black young adults with positive mental health help-seeking attitudes were 34% less likely to attempt suicide (OR = 0.66; 95% CI: 0.46, 0.96) and 35% less likely to experience suicide ideation (OR = 0.65; 95% CI: 0.47, 0.89). However, those young adults who experienced discrimination daily were more likely to report having attempted suicide (OR = 1.70; 95% CI: 1.34, 2.15).

CONCLUSIONS

Our findings offer valuable insights into the complex interplay between experiences of discrimination, attitudes toward seeking mental health support, and suicidal behaviors. However, our research also underscores how experiences of discrimination can significantly exacerbate feelings of isolation, hopelessness, and inadequacy, further contributing to suicidal behaviors in this population. By promoting positive mental health help-seeking behaviors, actively addressing discrimination, and applying an intersectional approach to suicide prevention efforts, we can take significant strides towards building a more supportive and inclusive society. This approach aims to empower individuals to seek help, reduce the risk of suicidal behaviors, and create a more welcoming environment for all members of our community.

Sociodemographic and Clinical Characteristics of Older Adults With Suicide-Related Emergency Department Presentations

OBJECTIVES

To identify characteristics of older adult emergency department (ED) patients aged ≥65 with suicidal ideation and/or behavior.

METHODS

A single center retrospective chart review analyzed 392 patients (≥65) with suicidal ideation and/or behavior (2013-2019). Comprehensive full-text searches were used. Subgroup analyses for age and gender were conducted.

RESULTS

Depressive disorder was documented in 50% of cases. Notably, 54% of all women were prescribed antidepressants, compared to only 31% of men. Most patients had general medical conditions (74.5%) and chronic multimorbidity (71.2%). Social stress affected 40.1%; 35.7% were intoxicated upon presentation. Alcohol abuse was more common in the 65-74 age group, while dementia impacted 20% of those ≥75. Men had a six-fold higher 30-day post-discharge mortality.

DISCUSSION

Older ED patients with suicidal ideation and/or behavior exhibit typical characteristics. The dementia prevalence suggests tailored care for those ≥75, and the heightened post-discharge mortality rate in older men requires further research.

A Secondary Analysis of the Complex Interplay between Psychopathology, Cognitive Functions, Brain Derived Neurotrophic Factor Levels, and Suicide in Psychotic Disorders: Data from a 2-Year Longitudinal Study

Identifying phenotypes at high risk of suicidal behaviour is a relevant objective of clinical and translational research and can facilitate the identification of possible candidate biomarkers. We probed the potential association and eventual stability of neuropsychological profiles and serum BDNF concentrations with lifetime suicide ideation and attempts (LSI and LSA, respectively) in individuals with schizophrenia (SCZ) and schizoaffective disorder (SCA) in a 2-year follow-up study. A secondary analysis was conducted on a convenience sample of previously recruited subjects from a single outpatient clinic. Retrospectively assessed LSI and LSA were recorded by analysing the available longitudinal clinical health records. LSI + LSA subjects consistently exhibited lower PANSS-defined negative symptoms and better performance in the BACS-letter fluency subtask. There was no significant association between BDNF levels and either LSI or LSA. We found a relatively stable pattern of lower negative symptoms over two years among patients with LSI and LSA. No significant difference in serum BDNF concentrations was detected. The translational viability of using neuropsychological profiles as a possible avenue for the identification of populations at risk for suicide behaviours rather than the categorical diagnosis represents a promising option but requires further confirmation.

Workforce estimate to treat mental disorders in the Kingdom of Saudi Arabia

BACKGROUND

Mental, neurological, and substance abuse (MNS) disorders describe a range of conditions that affect the brain and cause distress or functional impairment. In the Middle East and North Africa (MENA), MNS disorders make up 10.88 percent of the burden of disease as measured in disability-adjusted life years. The Kingdom of Saudi Arabia (KSA) is one of the main providers of mental health services and one of the largest contributors to mental health research in the region. Within the past decade, mental health resources and services has increased.

METHODS

We employ a needs-based workforce estimate as a planning exercise to arrive at the total number of psychiatrists, nurses, and psychosocial care providers needed to meet the epidemiological need of mental health conditions of the population of KSA. Estimates for a potential mental health workforce gap were calculated using five steps: Step 1-Quantify target population for priority mental health conditions. Step 2-Identify number of expected cases per year. Step 3-Set target service coverage for each condition. Step 4-Estimate cost-effective health care service resource utilization for each condition. Step 5-Estimate service resources needed for each condition.

RESULTS

The planning exercise indicates an epidemiologic need for a total of 17,100 full-time-equivalent (FTE) health care providers to treat priority MNS disorders. KSA appears to have a need-based shortage of 10,400 health workers to treat mental disorders. A total of 100 psychiatrists, 5700 nurses, and 4500 psychosocial care providers would be additionally needed (that is, above and beyond current levels) to address the priority mental health conditions. The shortfall is particularly severe for nurses and psychosocial workers who make up 98.9 percent of the shortfall. This shortage is substantial when compared to other high-income countries. Overall, the workforce needed to treat MNS conditions translates to 49.2 health workers per 100,000 population.

CONCLUSION

Challenges to addressing the shortfall are Saudi specific which includes awareness of cultural customs and norms in the medical setting. These challenges are compounded by the lack of Saudi nationals in the mental health workforce. Saudi nationals make up 29.5 percent of the physician workforce and 38.8 percent of the nursing workforce. Policymakers and planners supplement this shortfall with non-Saudi providers, who must be mindful of Saudi-specific cultural considerations. Potential solutions to reducing the shortfall of mental health care workers includes nurse task shifting and training of general practitioners to screen for, and treat, a subset of MNS disorders.

Suicide Following a Near-Death Experience

Background: Sometimes during real or presumed life-threatening and/or near-death circumstances, an individual undergoes an altered state of consciousness referred to as a near-death experience (NDE). The prevalent position in the field of NDE research for the last several decades has been that such experiences result in positive antisuicidal attitudes and that it is highly unlikely that experients will try to kill themselves afterward. In addition, the important consideration of passive suicidal ideation is neglected in NDE research. Aims: To question the premature assumption that people are highly unlikely to die by suicide after an NDE. Method: Four case studies of suicide after an NDE are provided and examined. Results: Although important quantitative data are still needed, it can no longer be argued that people do not die by suicide after an NDE. Limitations: Only four cases were available for examination, and the degree of impact that the NDE had on their suicide is uncertain. Conclusion: Much more research is needed on suicide risk post NDE. In the meantime, the NDE should not be ignored in suicide assessments, but therapists and other relevant professionals need to be attentive to any possible indications of either active or passive suicidal ideation post NDE.

Identifying novel proteins for suicide attempt by integrating proteomes from brain and blood with genome-wide association data

Genome-wide association studies (GWASs) have identified risk loci for suicide attempt (SA), but deciphering how they confer risk for SA remains largely unknown. This study aims to identify the key proteins and gain insights into SA pathogenesis. We integrated data from the brain proteome (N = 376) and blood proteome (N = 35,559) and combined it with the largest SA GWAS summary statistics to date (N = 518,612). A comprehensive set of methods was employed, including Mendelian randomization (MR), Steiger filtering, Bayesian colocalization, proteome‑wide association studies (PWAS), transcript-levels, cell-type specificity, correlation, and protein-protein interaction (PPI) network analysis. Validation was performed using other protein datasets and the SA dataset from FinnGen study. We identified ten proteins (GLRX5, GMPPB, B3GALTL, FUCA2, TTLL12, ADCK1, MMAA, HIBADH, ACP1, DOC2A) associated with SA in brain proteomics. GLRX5, GMPPB, and FUCA2 showed strong colocalization evidence and were supported by PWAS and transcript-level analysis, and were predominantly expressed in glutamatergic neuronal cells. In blood proteomics, one significant protein (PEAR1) and three near-significant proteins (NDE1, EVA1C, B4GALT2) were identified, but lacked colocalization evidence. Moreover, despite the limited correlation between the same protein in brain and blood, the PPI network analysis provided new insights into the interaction between brain and blood in SA. Furthermore, GLRX5 was associated with the GSTP1, the target of Clozapine. The comprehensive analysis provides strong evidence supporting a causal association between three genetically determined brain proteins (GLRX5, GMPPB, and FUCA2) with SA. These findings offer valuable insights into SA's underlying mechanisms and potential therapeutic approaches.

Client-reported impact of the Attempted Suicide Short Intervention Program

BACKGROUND

A history of attempted suicide is the most significant predictor of suicidal death. Several brief interventions aimed at tertiary suicide prevention have been investigated in clinical trials. However, suicide attempt survivors' experiences of such interventions have rarely been reported.

OBJECTIVE

To explore how suicide attempt survivors perceive the impact of the Attempted Suicide Short Intervention Program (ASSIP).

METHOD

We interviewed 14 Finnish adults who had received ASSIP as an adjunct to treatment as usual. Semi-structured interviews took place 4-10 weeks after the last ASSIP session. A conventional content analysis of the interview data is presented.

RESULTS

Three core categories depicting ASSIP's perceived impact were identified. The core category life-affirming change comprised subcategories of feeling better, thinking differently, acting differently, and having new resources. The core category collateral effects comprised difficult feelings and cognitive overload. The core category incompleteness of change comprised lack of desired change, gains as incomplete, need for sustenance, and unrealized potential.

CONCLUSION

Clients perceived ASSIP as effectively facilitating life-affirming change but agreed that further support was necessary to retain and build on these gains. Identified needs for improvement included more predictable post-ASSIP service paths and more support for involving affected loved ones.

Youth Suicide and Preceding Mental Health Diagnosis

Importance

Suicide is a leading cause of death among US youths, and mental health disorders are a known factor associated with increased suicide risk. Knowledge about potential sociodemographic differences in documented mental health diagnoses may guide prevention efforts.

Objective

To examine the association of documented mental health diagnosis with (1) sociodemographic and clinical characteristics, (2) precipitating circumstances, and (3) mechanism among youth suicide decedents.

Design, Setting, and Participants

This retrospective, cross-sectional study of youth suicide decedents aged 10 to 24 years used data from the Centers for Disease Control and Prevention National Violent Death Reporting System from 2010 to 2021. Data analysis was conducted from January to November 2023.

Exposures

Sociodemographic characteristics, clinical characteristics, precipitating circumstances, and suicide mechanism.

Main Outcomes and Measures

The primary outcome was previously documented presence of a mental health diagnosis. Associations were evaluated by multivariable logistic regression.

Results

Among 40 618 youth suicide decedents (23 602 aged 20 to 24 years [58.1%]; 32 167 male [79.2%]; 1190 American Indian or Alaska Native [2.9%]; 1680 Asian, Native Hawaiian, or Other Pacific Islander [4.2%]; 5118 Black [12.7%]; 5334 Hispanic [13.2%]; 35 034 non-Hispanic; 30 756 White [76.1%]), 16 426 (40.4%) had a documented mental health diagnosis and 19 027 (46.8%) died by firearms. The adjusted odds of having a mental health diagnosis were lower among youths who were American Indian or Alaska Native (adjusted odds ratio [aOR], 0.45; 95% CI, 0.39-0.51); Asian, Native Hawaiian, or Other Pacific Islander (aOR, 0.58; 95% CI, 0.52-0.64); and Black (aOR, 0.62; 95% CI, 0.58-0.66) compared with White youths; lower among Hispanic youths (aOR, 0.76; 95% CI, 0.72-0.82) compared with non-Hispanic youths; lower among youths aged 10 to 14 years (aOR, 0.70; 95% CI, 0.65-0.76) compared with youths aged 20 to 24 years; and higher for females (aOR, 1.64; 95% CI, 1.56-1.73) than males. A mental health diagnosis was documented for 6308 of 19 027 youths who died by firearms (33.2%); 1691 of 2743 youths who died by poisonings (61.6%); 7017 of 15 331 youths who died by hanging, strangulation, or suffocation (45.8%); and 1407 of 3181 youths who died by other mechanisms (44.2%). Compared with firearm suicides, the adjusted odds of having a documented mental health diagnosis were higher for suicides by poisoning (aOR, 1.70; 95% CI, 1.62-1.78); hanging, strangulation, and suffocation (aOR, 2.78; 95% CI, 2.55-3.03); and other mechanisms (aOR, 1.59; 95% CI, 1.47-1.72).

Conclusions and Relevance

In this cross-sectional study, 3 of 5 youth suicide decedents did not have a documented preceding mental health diagnosis; the odds of having a mental health diagnosis were lower among racially and ethnically minoritized youths than White youths and among firearm suicides compared with other mechanisms. These findings underscore the need for equitable identification of mental health needs and universal lethal means counseling as strategies to prevent youth suicide.

Risk factors of suicide re-attempt: A two-year prospective study

BACKGROUND

History of suicide attempt (SA) is the strongest predictor of a new SA and suicide. It is primordial to identify additional risk factors of suicide re-attempt. The aim of this study was to identify risk factors of suicide re-attempt in patients with recent SA followed for 2 years.

METHODS

In this multicentric cohort of adult inpatients, the median of the index SA before inclusion was 10 days. Clinicians assessed a large panel of psychological dimensions using validated tools. Occurrence of a new SA or death by suicide during the follow-up was recorded. A cluster analysis was used to identify the dimensions that best characterized the population and a variable "number of personality traits" was created that included the three most representative traits: anxiety, anger, and anxious lability. Risk factors of re-attempt were assessed with adjusted Cox regression models.

RESULTS

Among the 379 patients included, 100 (26.4 %) re-attempted suicide and 6 (1.6 %) died by suicide. The two major risk factors of suicide re-attempt were no history of violent SA and presenting two or three personality traits among trait anxiety, anger and anxious lability.

LIMITATIONS

It was impossible to know if treatment change during follow-up occur before or after the re-attempt.

DISCUSSION

One of the most important predictors of re-attempt in suicide attempters with mood disorders, was the presence of three personality traits (anger, anxiety, and anxious lability). Clinicians should provide close monitoring to patients presenting these traits and proposed treatments specifically targeting these dimensions, especially anxiety.

The development of suicide risk in people with severe mental disorders during the first year of the COVID-19 pandemic: a claims-based cohort study

PURPOSE

In this study, we assess how the first and second waves of the COVID-19 pandemic influenced the suicide risk of patients with severe mental disorders in Germany.

METHODS

We analyzed German health insurance claims data to compare the suicide risk of patients with severe mental disorders before and during the pandemic. We included n = 690,845 patients between October 2019 and March 2020 and n = 693,457 patients the corresponding period of the previous year and applied entropy balancing to adjust for confounding covariates. Given that the cause of death was unknown, we defined potential suicides as deaths of patients with a history of intentional self-harm whose passing could not be explained by COVID-19. Potential suicides were tracked in both cohorts over one year and compared using logistic regression.

RESULTS

128 potential suicides were identified in the period during and 101 before the pandemic. This corresponded to a significant increase in the risk for potential suicide of 27.4% compared to the control period (β = 0.24, z = 1.82, p < 0.05).

CONCLUSION

The noticeable increase in the risk for potential suicide for patients with severe pre-existing mental disorders emphasizes the call for additional efforts to prevent suicide and to help patients cope with their mental illness in the aftermath of the COVID-19 crisis.

Mental Health Treatment Use, Perceived Treatment Need, and Reasons for Non-Use Among U.S. Adults with Serious Suicidal Thoughts During the COVID-19 Pandemic

Analyzing the 2021 National Survey on Drug Use and Health data with generalized linear models, we examined: (1) COVID pandemic-related and other correlates of mental health treatment use and unmet perceived treatment need among U.S. adults who experienced serious suicidal thoughts (N = 3,177); and (2) correlates of self-reported reasons for not receiving treatment. We found that 61% used any mental health treatment, and 48% of users and 37% of nonusers reported perceived treatment need. Significant correlates of treatment use were demographic factors, insurance, major depressive disorder, and illicit drug use disorder. Significant correlates of perceived treatment need were age 18-34, some college education, and major depressive episode. Perceived negative effect of the COVID pandemic on mental health was a significant factor for both treatment use and perceived need. The most frequent reasons for not getting treatment were the cost of treatment or lack of insurance and stigma-related concerns.

Perceived Usefulness of Self-Guided Versus Collaborative Suicide Safety Plans in Online Help-Seekers

Background: Suicide safety plans were originally devised to be paper-based and clinician-guided, but digital self-guided plans are now common. Aim: This study explored whether plan format (paper vs. digital), assistance (self-authored vs. collaboration), and suicide attempt history were associated with differences in suicidal ideation, suicide-related coping, and perceived usefulness. Method: An online sample of safety plan users (N = 131) completed a survey assessing suicidal ideation, suicide-related coping, and perceived usefulness of their plan. t tests compared outcomes by plan format, collaboration, and suicide attempt history. Pearson correlations explored associations between reasons for plan use, suicidal ideation, and suicide-related coping. Results: Suicidal ideation was significantly higher, and perceived usefulness significantly lower in participants with a past suicide attempt (vs. none) and in those who had collaborated to make their safety plan (vs. self-authored). Collaborators were largely health professionals. No significant differences were found between plan formats. Suicide-related coping was associated with higher perceived usefulness overall. Limitations: Our study design was cross-sectional, utilizing a largely young, female, English-speaking, online help-seeking sample. Conclusions: For clients with prior suicide attempts and higher levels of suicidal ideation, meaningful collaboration may be needed to find safety plan coping strategies that are perceived as useful.

Commercially Sexually Exploited Adolescent Girls: The Association Between Externalizing Disorders and Parental Incarceration with Suicide Attempts

Commercial sexual exploitation (CSE) is a significant public health concern disproportionately affecting ethnoracially minoritized girls. Despite strong associations of CSE with suicide attempts, little is known about correlates of suicide among girls with CSE histories. Elevated rates of externalizing disorders (i.e., attention-deficit/hyperactivity disorder [ADHD], disruptive behavior disorders [DBD], conduct disorder [CD]) were observed among CSE youth, particularly in ethnoracially minoritized samples. Youth with CSE histories are frequently affected by parental incarceration, which is correlated with risk for suicide attempts. We tested cross-sectional simultaneous associations of externalizing disorders and parental incarceration with number of suicide attempts among 360 ethnoracially diverse girls affected by CSE (Mean age = 18.86). ADHD, DBD, and maternal incarceration were positively associated with number of suicide attempts. Findings implicate clinical/familial correlates of suicide attempts in this marginalized group, suggesting early suicide prevention efforts may improve traction on this problem by focusing on individual and family level factors.

The association between ketamine and esketamine and suicidality: reports to the Food And Drug Administration Adverse Event Reporting System (FAERS)

INTRODUCTION

Replicated evidence indicates that ketamine and esketamine reduce measures of suicidality in persons with treatment-resistant depression (TRD). It remains uncertain whether individuals experience worsening of preexisting suicidality with either agent.

RESEARCH DESIGN AND METHODS

The Food and Drug Administration Adverse Event Reporting System (FAERS) database was searched from 1970 and 2019 to 30 September 2023 for reports of suicidal ideation, depression suicidal, suicidal behavior, suicidal attempt, and completed suicide in association with ketamine and esketamine exposure, respectively. We present reporting odds ratios (ROR) significance was determined when the lower limit of the 95% confidence interval (CI) exceeded 1.0. Lithium was used as the control agent.

RESULTS

Observed a higher ROR for suicidal ideation (ROR 7.58, 95% CI 6.34-9.07) and depression suicidal (ROR 14.19, 95% CI 1.80-112.07) with esketamine. Significantly lower RORs were observed for suicide attempt with ketamine (ROR 0.15, 95% CI 0.11-0.21) and esketamine (ROR 0.57, 95% CI 0.48-0.67).

CONCLUSIONS

Mixed RORs across aspects of suicidality were observed with ketamine and esketamine. Limitations of the FAERS database prevent any determination of causal effects new onset suicidality to either agent. The lower RORs for suicide attempt with ketamine and esketamine is noted but cannot be interpreted as a direct therapeutic effect.

Decoding Suicide Decedent Profiles and Signs of Suicidal Intent Using Latent Class Analysis

Importance

Suicide rates in the US increased by 35.6% from 2001 to 2021. Given that most individuals die on their first attempt, earlier detection and intervention are crucial. Understanding modifiable risk factors is key to effective prevention strategies.

Objective

To identify distinct suicide profiles or classes, associated signs of suicidal intent, and patterns of modifiable risks for targeted prevention efforts.

Design, Setting, and Participants

This cross-sectional study used data from the 2003-2020 National Violent Death Reporting System Restricted Access Database for 306 800 suicide decedents. Statistical analysis was performed from July 2022 to June 2023.

Exposures

Suicide decedent profiles were determined using latent class analyses of available data on suicide circumstances, toxicology, and methods.

Main Outcomes and Measures

Disclosure of recent intent, suicide note presence, and known psychotropic usage.

Results

Among 306 800 suicide decedents (mean [SD] age, 46.3 [18.4] years; 239 627 males [78.1%] and 67 108 females [21.9%]), 5 profiles or classes were identified. The largest class, class 4 (97 175 [31.7%]), predominantly faced physical health challenges, followed by polysubstance problems in class 5 (58 803 [19.2%]), and crisis, alcohol-related, and intimate partner problems in class 3 (55 367 [18.0%]), mental health problems (class 2, 53 928 [17.6%]), and comorbid mental health and substance use disorders (class 1, 41 527 [13.5%]). Class 4 had the lowest rates of disclosing suicidal intent (13 952 [14.4%]) and leaving a suicide note (24 351 [25.1%]). Adjusting for covariates, compared with class 1, class 4 had the highest odds of not disclosing suicide intent (odds ratio [OR], 2.58; 95% CI, 2.51-2.66) and not leaving a suicide note (OR, 1.45; 95% CI, 1.41-1.49). Class 4 also had the lowest rates of all known psychiatric illnesses and psychotropic medications among all suicide profiles. Class 4 had more older adults (23 794 were aged 55-70 years [24.5%]; 20 100 aged ≥71 years [20.7%]), veterans (22 220 [22.9%]), widows (8633 [8.9%]), individuals with less than high school education (15 690 [16.1%]), and rural residents (23 966 [24.7%]).

Conclusions and Relevance

This study identified 5 distinct suicide profiles, highlighting a need for tailored prevention strategies. Improving the detection and treatment of coexisting mental health conditions, substance and alcohol use disorders, and physical illnesses is paramount. The implementation of means restriction strategies plays a vital role in reducing suicide risks across most of the profiles, reinforcing the need for a multifaceted approach to suicide prevention.

Risk factors for mortality after hospitalization for suicide attempt: results of 11-year follow-up study in Piedmont Region, Italy

PURPOSE

Suicide attempters are at high risk of premature death, both for suicide and for non-suicidal causes. The aim of this study is to investigate risk factors and temporal span for mortality in a cohort of cases admitted to hospital for suicide attempt.

METHODS

The cohort included 1489 patients resident in Piedmont Region, North West of Italy, who had been admitted to hospital or emergency department for suicide attempt between 2010 and 2020. Cox regression models were used to identify risk factors for death. The final multivariate model included gender, age, area deprivation index, family composition, psychiatric disorders, malignant neoplasms, neurological disorders, diabetes mellitus, cardiovascular diseases, chronic obstructive pulmonary disease, and intracranial injury or skull fracture.

RESULTS

During the observation period, 7.3% of patients died. The highest mortality was observed within the first 12 months after suicide attempt, and remained elevated for many years afterwards. Male gender, older age, high deprivation index of the census area, single-parent family, mood disorders, malignant neoplasms, diabetes mellitus and intracranial injuries or skull fracture were independent predictors of death. Risk factors for natural and unnatural causes of death were also identified.

CONCLUSIONS

The mortality risk of suicide attempters is very high, both in the months immediately following the attempt and afterwards. The identification of high-risk groups can help to plan outpatient care following the hospital discharge. Our findings urge the need to design strategies for the assistance and care of these patients at long term in order to reduce the unfavourable outcomes.

Burden of the Fruity: Family Support and Suicide Ideation as Mediators Between Discrimination and Suicide Behavior in LGBTQ+ Malaysians

Malaysian pervasive climate places its LGBTQ+ residents at heightened risk for suicidal behaviors (SB). This cross-sectional study aimed to elucidate connections between minority stressors (discrimination), types of social supports, and suicidality in this marginalized population. Utilizing online surveys, 317 LGBTQ+ Malaysians aged 18-49 provided data regarding experienced discrimination, perceived social support from family, friends, and significant others, suicidal ideation (SI), and SB. Quantitative analyses illuminated several key findings. First, discrimination is positively associated with SB, while all support types are inversely related to SB, with family support demonstrating the strongest correlation. Regression modeling revealed family support as the sole unique predictor of reduced SB. Serial mediation analysis uncovered nuanced indirect pathways from discrimination to SB, with SI, but not family support alone, significantly mediating this relationship. However, reduced family support resulting from discrimination sequentially heightened SI and SB. Despite pervasive societal bias, family and friend acceptance may curb the LGBTQ+ community's elevated suicide risk by mitigating resultant ideation. These insights highlight the need for public health initiatives promoting social support and LGBTQ+ inclusivity laying the groundwork to safeguard this population's psychological wellbeing.

A narrative review: suicide and suicidal behaviour in older adults

Globally, suicide is a public health concern that claims the lives of many each year. The complex etiology and factors contributing to the risk of suicide make it hard to predict the likelihood of death by suicide. Suicide rates have been increasing over the past 25 years in patients aged 65 years and older, and with the expected increases in the size of the older adult population and the under-detection of suicide risk, these rates may continue to increase. To mitigate and attempt to limit this expected increase, it is important to understand the risk and protective factors of suicide in older adults. This narrative review focuses on individuals above the age of 65 and encompasses relevant peer-reviewed publications from the past 25 years to cover fatal and non-fatal suicidal behaviour. It summarizes several important risk factors for suicide and suicidal behaviors while considering how risk can be detected, assessed, prevented, and mitigated. Screening methods to detect suicide and depression in older adults were examined based on their effectiveness and suitability for use in this population. Lastly, the impacts of the COVID-19 pandemic on suicide rates in older adults were described.

Depression in older women who died by suicide: associations with other suicide contributors and suicide methods

Suicides among older women have received little research attention. In this study based on the 2017-2019 National Violent Death Reporting System data, we examined the prevalence of depression in older female suicide decedents (N = 3,061), associations between depression and other suicide precipitants, and the associations between suicide methods and depression. Descriptive statistics and generalized linear models (GLM) for a Poisson distribution with a log link were used to examine the research questions. Of the decedents, 15.0% had depressed mood without a reported diagnosis and 41.8% had a depression diagnosis. Nearly one-half of the decedents with reported depression were receiving mental health/substance use treatment at the time of injury. The likelihood of depression was lower among those who were age 85 and older compared to those were age 65-74, but higher among those who had anxiety disorder (IRR = 1.50, 95% CI = 1.33-1.69), history of suicidal ideation (IRR = 1.22, 95% CI = 1.10-1.35), history of suicide attempt (IRR = 1.27, 95% CI = 1.14-1.41), and bereavement problems (IRR = 1.45, 95% CI = 1.27-1.65). Those who had depression were less likely to have used firearms (IRR = 0.85, 95% CI = 0.75-0.97) but more likely to have used hanging/suffocation (IRR = 1.37, 95% CI = 1.13-1.67). The findings show that gun ownership was likely an important factor for firearm use. The high prevalence of depressed mood and/or depression diagnosis among older female suicide decedents at the time of their fatal injury underscores the importance of assessing depression and providing evidence-based depression treatment as an essential suicide prevention approach.

Clinical, behavioral, and electrophysiological profiles along a continuum of suicide risk: evidence from an implicit association task

BACKGROUND

An urgent need exists to identify neural correlates associated with differing levels of suicide risk and develop novel, rapid-acting therapeutics to modulate activity within these neural networks.

METHODS

Electrophysiological correlates of suicide were evaluated using magnetoencephalography (MEG) in 75 adults with differing levels of suicide risk. During MEG scanning, participants completed a modified Life-Death Implicit Association Task. MEG data were source-localized in the gamma (30-58 Hz) frequency, a proxy measure of excitation-inhibition balance. Dynamic causal modeling was used to evaluate differences in connectivity estimates between risk groups. A proof-of-concept, open-label, pilot study of five high risk participants examined changes in gamma power after administration of ketamine (0.5 mg/kg), an NMDAR antagonist with rapid anti-suicide ideation effects.

RESULTS

Implicit self-associations with death were stronger in the highest suicide risk group relative to all other groups, which did not differ from each other. Higher gamma power for self-death compared to self-life associations was found in the orbitofrontal cortex for the highest risk group and the insula and posterior cingulate cortex for the lowest risk group. Connectivity estimates between these regions differentiated the highest risk group from the full sample. Implicit associations with death were not affected by ketamine, but enhanced gamma power was found for self-death associations in the left insula post-ketamine compared to baseline.

CONCLUSIONS

Differential implicit cognitive processing of life and death appears to be linked to suicide risk, highlighting the need for objective measures of suicidal states. Pharmacotherapies that modulate gamma activity, particularly in the insula, may help mitigate risk.Clinicaltrials.gov identifier: NCT02543983, NCT00397111.

Variations in Suicide Risk and Risk Factors After Hospitalization for Depression in Finland, 1996-2017

Importance

Although incidence of suicide in depression varies remarkably temporally, risk factors have been modeled as constant and remain uncharted in the short term. How effectively factors measured at one point in time predict risk at different time points is unknown.

Objective

To examine the absolute risk and risk factors for suicide in hospitalized patients with depression starting from the first days after discharge up to 2 years and to evaluate whether the size of relative risk by factor displays temporal patterns over consecutive phases of follow-up.

Design, Setting, and Participants

This population-based study using Finnish registers (hospital discharge, population, and cause of death registers) included all hospitalizations for depression as the principal diagnosis in Finland from 1996 to 2017, with a maximum follow-up of 2 years. Data were analyzed from January 2022 to November 2023.

Main Outcomes and Measures

Incidence rate (IR), IR ratios, hazard functions, and hazard ratios for suicide by consecutive time periods (0 to 3 days, 4 to 7 days, 7 to 30 days, 31 to 90 days, 91 to 365 days, and 1 to 2 years) since discharge.

Results

This study included 193 197 hospitalizations among 91 161 individuals, of whom 51 197 (56.2%) were female, and the mean (SD) age was 44.0 (17.3) years. Altogether, patients were followed up to 226 615 person-years. A total of 1219 men and 757 women died of suicide. Incidence of suicide was extremely high during the first days after discharge (IR of 6062 [95% CI, 4963-7404] per 100 000 on days 0 to 3; IR of 3884 [95% CI, 3119-4835] per 100 000 on days 4 to 7) and declined thereafter. Several factors were associated with risk of suicide over the first days after discharge. Current suicide attempt by hanging or firearms increased the risk of suicide most on days 0 to 3 (IR ratio, 18.9; 95% CI, 3.1-59.8) and on days 0 to 7 (IR ratio, 10.1; 95% CI, 1.7-31.5). Temporal patterns of the size of the relative risk diverged over time, being constant, declining, or increasing. Clinical factors had the strongest association immediately. Relative risk remained constant among men and even increased among those with alcohol or substance use disorder.

Conclusions and Relevance

In this study, patients hospitalized for depression had extremely high risk of suicide during the first days after discharge. Thereafter, incidence declined steeply but remained high. Within the periods of the highest risk of suicide, several factors increased overall risk manyfold. Risk factors' observed potencies varied over time and had characteristic temporal patterns.

Serum lipids as predictive markers for death by suicide

Serum lipid levels have been associated with an increased risk of suicidal behaviors. This retrospective cohort study aimed to investigate the association between serum lipid levels and death by suicide among suicide attempters according to sex. Suicide attempters visiting emergency departments between 2007 and 2011 were followed up until the date of all-cause death or December 31, 2012. Sex-stratified Cox proportional hazards regression and competing risk models were constructed to obtain the hazard ratios (HR) of serum lipid measures and suicide. For each significant lipid variable in the final models, Kaplan-Meier survival analysis and cumulative incidence function (CIF) were employed to compare the time to suicide between the high- and low-lipid groups based on the best cutoff point from the receiver operating characteristic curve. In 408 female attempters (65.8 %), the HR in the Cox regression model and subdistribution HR in the competing risk model for increased total cholesterol (TC) were 0.968 and 0.970, respectively. In the Kaplan-Meier survival analysis and CIF, increased death by suicide was demonstrated in the low-TC group (< 165 mg/dL). Lower serum TC levels among female suicide attempters may predict suicide. More careful monitoring is warranted in women with lower TC levels who recently attempted suicide.

Association of clinical characteristics, depression remission and suicide risk with discrepancies between self- and clinician-rated suicidal ideation: Two large naturalistic cohorts of outpatients with depression

Clinician- and self-rating of suicidal ideation (SI) are often discrepant. The aim of this study was to determine: 1) Association between discrepant self- and clinician-rated SI with clinical characteristics, depression remission and SA (SA) risk; 2) which SI assessment (self or clinician) predicted depression remission and risk of SA. LUEUR and GENESE are two large, prospective, naturalistic cohorts of French adult outpatients with unipolar depression treated and followed for 6 weeks. SI presence was assessed and defined with a score to the suicidal item of the Montgomery-Åsberg Depression Rating Scale ≥3. Discordant SI was defined as SI detection by only one of the two evaluators (patient or clinician). In both cohorts, 49.3 % (GENESE) and 34 % (LUEUR) patients had discordant SI. Clinical characteristics were more severe, and risk of SA was higher in patients with current SI (concordant and discordant) than in patients without SI and in the concordant than in the discordant group. Prediction of the risk of SA and of depression non-remission was comparable by the two ratings. Patients with SI (concordant and discordant) have more severe clinical characteristics and patients with concordant SI are the most at risk of SA during the follow-up. It is crucial to assess SI and to improve how it is evaluated.

ADHD Patients with Suicidal Behaviour: Risk Factors, Comorbidities, and Clinical Profile: A Naturalistic Exploratory Study

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that disrupts brain functioning and is characterized by hyperactivity, impulsivity, and inattention. With varying presentations and complex etiological factors contributing to the development of ADHD, along with its persistence into adulthood, ADHD must be studied. Researchers have taken an interest in the relationship between ADHD and suicide, which is a serious public health concern with increasing prevalence rates in the Americas. The current literature reveals conflicting views on the importance of psychiatric comorbidities in the development of suicidal behaviours in ADHD patients. Therefore, this study aimed to determine whether there were significant differences between adult ADHD patients with suicide risk and adult ADHD patients without suicide risk. This study was a naturalistic retrospective chart review pilot study that used a sample of adults with a confirmed diagnosis of ADHD from January 2023 to August 2023. Using convenience sampling and sets of inclusion and exclusion criteria, patient data were sequentially collected from Med Access electronic medical records. The control and experimental groups each consisted of 50 patients (100) ranging from 19 to 58 years old. Our quantitative data were analyzed using non-parametric statistical tests, including the Chi-Square test and the Mann-Whitney U test. The results showed significant associations between ADHD patients with suicide risk and (1) borderline personality disorder; (2) binge eating disorder; (3) seven specific psychosocial risk factors; and (4) a higher number of antidepressant medication trials. No significant associations were found with other psychiatric disorders; however, there are important sex differences in terms of the risk factors. Our pilot study reveals several significant differences between adult ADHD patients with suicide risk and those without suicide risk. However, given our limited sample size and limitations, we hope our study encourages larger-scale studies to further investigate this relationship to improve its generalizability.

Risk factors of reattempt among suicide attempters in South Korea: A nationwide retrospective cohort study

This study aimed to identify underlying demographic and clinical characteristics among individuals who had previously attempted suicide, utilizing the comprehensive Health Insurance Review and Assessment Service (HIRA) database. Data of patients aged 18 and above who had attempted suicide between January 1 and December 31, 2014, recorded in HIRA, were extracted. The index date was identified when a suicide attempt was made within the year 2014. The medical history of the three years before the index date and seven years of follow-up data after the index date were analyzed. Kaplan-Meier estimate was used to infer reattempt of the suicide attempters, and Cox-proportional hazard analysis was used to investigate risk factors associated with suicide reattempts. A total of 17,026 suicide attempters were identified, of which 1,853 (10.9%) reattempted suicide; 4,925 (28.9%) patients had been diagnosed with depressive disorder. Of the reattempters, 391 (21.1%) demonstrated a history of suicide attempts in the three years before the index date, and the mean number of prior attempts was higher compared to that of the non-reattempters (1.7 vs.1.3, p-value < 0.01). Prior psychiatric medication, polypharmacy, and an increase in the number of psychotropics were associated with suicide reattempt in overall suicide attempters. (Hazard ratio (HR) = 3.20, 95% confidence interval [CI] = 2.56-4.00; HR = 2.42, 95% CI = 1.87-3.14; HR = 19.66, 95% CI = 15.22-25.39 respectively). The risk of reattempt decreased in individuals receiving antidepressant prescriptions compared to those unmedicated, showing a reduction of 78% when prescribed by non-psychiatrists and 89% when prescribed by psychiatrists. Similar risk factors for suicide reattempts were observed in the depressive disorder subgroup, but the median time to reattempt was shorter (556.5 days) for this group compared to that for the overall attempters (578 days). Various risk factors including demographics, clinical characteristics, and medications should be considered to prevent suicide reattempts among suicide attempters, and patients with depressive disorder should be monitored more closely.

The influence of psychotherapy on individuals who have attempted suicide: A systematic review and meta-analysis

INTRODUCTION

Suicide is a serious global public health issue, and a history of attempted suicide is the most critical indicator of suicide risk. There are limited studies on the effectiveness of psychotherapy in individuals who have attempted suicide, and other outcome measures related to suicide risk in suicide attempts have not been explored.

AIM/QUESTION

This study aimed to systematically review and perform a meta-analysis of the effectiveness of psychotherapy on individuals who have attempted suicide.

METHODS

This study conducted a comprehensive literature search of five major databases (PubMed, EMBASE, Cochrane, Web of Science, and Ovid). The protocol for this study is registered with PROSPERO (CRD42023464401) and follows the PRISMA guidelines.

RESULTS

This meta-analysis included a total of 34 trials from 32 literature sources. The study involved a total of 6600 participants. The results showed that psychotherapy had a positive effect on reducing the suicidal tendencies of individuals who have attempted suicide and effectively reduced the number of repeated suicide attempts as well as the levels of suicidal ideation, depression, anxiety and hopelessness.

IMPLICATIONS FOR PRACTICE

This study concludes that psychotherapy is effective in reducing the suicidal tendencies of individuals who have attempted suicide. Psychological therapy for individuals who have attempted suicide are crucial in preventing future suicidal behaviours.

Developing a risk prediction model for death at first suicide attempt-Identifying risk factors from Thailand's national suicide surveillance system data

More than 60% of suicides globally are estimated to take place in low- and middle-income nations. Prior research on suicide has indicated that over 50% of those who die by suicide do so on their first attempt. Nevertheless, there is a dearth of knowledge on the attributes of individuals who die on their first attempt and the factors that can predict mortality on the first attempt in these regions. The objective of this study was to create an individual-level risk-prediction model for mortality on the first suicide attempt. We analyzed records of individuals' first suicide attempts that occurred between May 1, 2017, and April 30, 2018, from the national suicide surveillance system, which includes all of the provinces of Thailand. Subsequently, a risk-prediction model for mortality on the first suicide attempt was constructed utilizing multivariable logistic regression and presented through a web-based application. The model's performance was assessed by calculating the area under the receiver operating curve (AUC), as well as measuring its sensitivity, specificity, and accuracy. Out of the 3,324 individuals who made their first suicide attempt, 50.5% of them died as a result of that effort. Nine out of the 21 potential predictors demonstrated the greatest predictive capability. These included male sex, age over 50 years old, unemployment, having a depressive disorder, having a psychotic illness, experiencing interpersonal problems such as being aggressively criticized or desiring plentiful attention, having suicidal intent, and displaying suicidal warning signals. The model demonstrated a good predictive capability, with an AUC of 0.902, a sensitivity of 84.65%, a specificity of 82.66%, and an accuracy of 83.63%. The implementation of this predictive model can assist physicians in conducting comprehensive evaluations of suicide risk in clinical settings and devising treatment plans for preventive intervention.

Effect of next-step antidepressant treatment on suicidal ideation: findings from the VAST-D trial

BACKGROUND

Major depressive disorder (MDD) contributes to suicide risk. Treating MDD effectively is considered a key suicide prevention intervention. Yet many patients with MDD do not respond to their initial medication and require a 'next-step'. The relationship between next-step treatments and suicidal thoughts and behaviors is uncharted.

METHOD

The VA Augmentation and Switching Treatments for Depression trial randomized 1522 participants to one of three next-step treatments: Switching to Bupropion, combining with Bupropion, and augmenting with Aripiprazole. In this secondary analysis, features associated with lifetime suicidal ideation (SI) and attempts (SA) at baseline and current SI during treatment were explored.

RESULTS

Compared to those with SI only, those with lifetime SI + SA were more likely to be female, divorced, or separated, unemployed; and to have experienced more childhood adversity. They had a more severe depressive episode and were more likely to respond to 'next-step' treatment. The prevalence of SI decreased from 46.5% (694/1492) at baseline to 21.1% (315/1492) at end-of-treatment. SI during treatment was associated with baseline SI; low positive mental health, more anxiety, greater severity and longer duration of current MDD episode; being male and White; and treatment with S-BUP or C-BUP as compared to A-ARI.

CONCLUSION

SI declines for most patients during next-step medication treatments. But about 1 in 5 experienced emergent or worsening SI during treatment, so vigilance for suicide risk through the entire 12-week acute treatment period is necessary. Treatment selection may affect the risk of SI.

Proximal characteristics of suicide attempts: a study in a public hospital in Spain

INTRODUCTION

Different parameters of suicide attempts treated since the implementation of the Attention to Suicide Risk Program (ARSUIC) in 2012 at the Hospital Ramón y Cajal in Madrid Region are described in this paper.

METHOD

The sample was composed of 107 patients and the information was collected through a questionnaire created ad hoc with the following variables: type of suicidal ideation; drug use immediately prior to the attempt; method (in case of drug overdosing: drug/s used); location; accessibility to rescue; planning; intentionality; criticism; and brakes.

RESULTS

Descriptive statistics were obtained and a comparison by gender was made through the χ2 and contingency coefficients tests. The data from the retrospective longitudinal study showed that the most common profile was of patients with unstructured ideas of death and no previous drug use who took an unplanned drug overdose in the family home, with the intention of self-harm or avoidance of discomfort, especially with benzodiazepines. Patients tend to ask for help afterwards and criticise the attempt, but potential restraints are often not recorded in the clinical report. Regarding the dissimilarities based on gender, statistically significant differences were found in prior alcohol consumption, in favour of men and in the overdose method, specifically with benzodiazepines, in favour of women.

CONCLUSIONS

Knowing the types of attempts at self-harm is essential for improving prevention, understanding and patient management.

Prenatal opioid use as a predictor of postpartum suicide attempts among reproductive-age women enrolled in Oregon Medicaid

BACKGROUND

The rates of suicide and opioid use disorder (OUD) among pregnant and postpartum women continue to increase. This research characterized OUD and suicide attempts among Medicaid-enrolled perinatal women and examined prenatal OUD diagnosis as a marker for postpartum suicide attempts.

METHODS

Data from Oregon birth certificates, Medicaid eligibility and claims files, and hospital discharge records were linked and analyzed. The sample included Oregon Medicaid women aged 15-44 who became pregnant and gave live births between January 2008 and January 2016 (N = 61,481). Key measures included indicators of suicide attempts (separately for any means and opioid poisoning) and OUD diagnosis, separately assessed during pregnancy and the one-year postpartum period. Probit regression was used to examine the overall relationship between prenatal OUD diagnosis and postpartum suicide attempts. A simultaneous equations model was employed to explore the link between prenatal OUD diagnosis and postpartum suicide attempts, mediated by postpartum OUD diagnosis.

RESULTS

Thirty-three prenatal suicide attempts by any means were identified. Postpartum suicide attempts were more frequent with 58 attempts, corresponding to a rate of 94.3 attempts per 100,000. Of these attempts, 79% (46 attempts) involved opioid poisoning. A total of 1,799 unique women (4.6% of the sample) were diagnosed with OUD either during pregnancy or one-year postpartum with 53% receiving the diagnosis postpartum. Postpartum suicide attempts by opioid poisoning increased from 55.5 per 100,000 in 2009 to 105.1 per 100,000 in 2016. The rate of prenatal OUD also almost doubled over the same period. Prenatal OUD diagnosis was associated with a 0.15%-point increase in the probability of suicide attempts by opioid poisoning within the first year postpartum. This increase reflects a three-fold increase compared to the rate for women without a prenatal OUD diagnosis. A prenatal OUD diagnosis was significantly associated with an elevated risk of postpartum suicide attempts by opioid poisoning via a postpartum OUD diagnosis.

CONCLUSIONS

The risk of suicide attempt by opioid poisoning is elevated for Medicaid-enrolled reproductive-age women during pregnancy and postpartum. Women diagnosed with prenatal OUD may face an increased risk of postpartum suicides attempts involving opioid poisoning.

Risk factors for suicidal attempts in a sample of outpatients with treatment-resistant depression: an observational study

Introduction

Treatment-resistant depression (TRD) is commonly defined as the failure of at least two trials with antidepressant drugs, given at the right dose and for an appropriate duration. TRD is associated with increased mortality, compared to patients with a simple major depressive episode. This increased rate was mainly attributed to death from external causes, including suicide and accidents. The aim of our study is to identify socio-demographic and psychopathological variables associated with suicidal attempts in a sample of outpatients with TRD.

Material and methods

We performed a monocentric observational study with a retrospective design including a sample of 63 subjects with TRD referred to an Italian outpatient mental health centre. We collected socio-demographic and psychopathological data from interviews and clinical records.

Results

77.8% of the sample (N=49) were females, the mean age was 49.2 (15.9). 33.3% (N=21) of patients had attempted suicide. 54% (N=34) of patients had a psychiatric comorbidity. Among the collected variables, substance use (p=0.031), psychiatric comorbidities (p=0.049) and high scores of HAM-D (p=0.011) were associated with the occurrence of suicide attempts. In the regression model, substance use (OR 6.779), psychiatric comorbidities (OR 3.788) and HAM-D scores (OR 1.057) were predictive of suicide attempts. When controlling for gender, only substance use (OR 6.114) and HAM-D scores (OR 1.057) maintained association with suicide attempts.

Conclusion

The integrated treatment of comorbidities and substance abuse, which involves different mental health services, is fundamental in achieving the recovery of these patients. Our study supports the importance of performing a careful clinical evaluation of patients with TRD in order to identify factors associated with increased risk of suicide attempts.

Suicide attempts in the adult Mexican population: an analysis of sociodemographic characteristics and associated factors

OBJECTIVE

Suicide is the culmination of a process or continuum known as suicidal behavior that proceeds from ideation and planning to attempt. The objective was to estimate the prevalence of suicide attempts in the adult Mexican population and to analyze their main associated factors.

METHODS

We conducted an observational, cross-sectional, and descriptive study with information from the National Health and Nutrition Survey (2018). Self-reported lifetime suicide attempt was used in the analysis. We analyzed depression, obesity, tobacco smoking, and alcohol consumption as suicide attempt-associated factors using a multivariate logistic regression model.

RESULTS

The prevalence of adult suicide attempt was 2.0% (95%CI 1.8-2.2) and it was higher among women (2.4%; 95%CI 2.2-2.8) and young people (2.9%; 95%CI 2.4-3.4). Low education (OR=1.6; 95%CI 1.2-2.2), being single (OR=1.3; 95%CI 1.0-1.6), having obesity (OR=1.4; 95%CI 1.1-1.8), consumption of alcohol (OR=2.4; 95%CI 1.7-3.4) or tobacco smoking (OR=1.8; 95%CI 1.4-2.4), and having strong symptoms of depression (OR=10.1; 95%CI 6.2-16.3) were associated with a higher prevalence of suicide attempts.

CONCLUSION

These results help better understand suicidal behavior in Mexico and identify the factors that increase the likelihood of suicide attempts, which is essential to help reduce suicide mortality. This research is crucial for developing early interventions and prevention programs aimed at reducing suicide's public health burden.

The forever decision: a qualitative study among survivors of a suicide attempt

Background

Suicide attempts have a profound emotional impact on both individuals and society as a whole. This qualitative study delves into three key aspects: 1) the progression through the suicidal process, 2) the influential factors facilitating the transition from ideation to attempt using the volitional moderators within the integrated motivational-volitional (IMV) model, and 3) preventive strategies impeding this transition from ideation to attempt.

Methods

Between October 1, 2022 and March 7, 2023 we interviewed 27 adults (23 women, four men, mean age 33 years) who attempted suicide within the past 12 months. Participants were recruited through social media and in collaboration with several mental health institutions in the Netherlands. The participants were initially screened and interviewed based on the Pathway to Suicidal Actions Interview. Analysis was performed employing the constant comparative method.

Findings

Despite the heterogeneity of the suicidal process, suicidal thoughts predominately emerged during adolescence (Mdn = 15, M = 17.8). In most participants, planning and preparatory actions occurred long before the attempt, with a median of six years prior to the attempt for the selection of the method. All volitional moderators were observed, although pain sensitivity in particular varied among participants. Access to lethal means and planning emerged as important moderators in the suicidal process. Asking the survivors what could have helped to prevent their attempts, most participants mentioned that they felt their suicidality was not taken seriously enough.

Interpretation

We discussed the significance of planning in the suicidal process, challenges in conceptualizing planning and impulsivity, and individual differences in pain sensitivity. Based on the findings, we underscore the critical need for restricting access to means, giving greater consideration to preparatory actions within the suicidal process, and fostering open dialogues about suicidality.

Funding

This research was funded by ProRail, the Dutch rail infrastructure manager in line with their work on mental health.

[Utilization of Outpatient Psychotherapy and Outpatient Psychiatric Treatment by Men and Women after Inpatient Treatment due to Suicide Attempt or Acute Suicidal Crisis]

OBJECTIVE

The strongest predictor of suicide attempts is a previous suicide attempt. Individuals hospitalized for suicidal ideation and behavior face an increased risk of suicide following discharge. This study investigates the extent to which outpatient treatment services are utilized the first 6 months after discharge and whether men and women differ in this regard.

METHOD

The study examines data of 124 individuals (with suicide attempts (lifetime), 59.7% female) on the use of outpatient treatment services in the 6 months after inpatient treatment.

RESULTS

37.9% (N=47) of individuals reported not having used any treatment services at all. Men were significantly less likely to make use of the services.

CONCLUSION

Members of a group with an increased risk of suicide, to a large extent, fail to make use of outpatient treatment services. Discharge management should increasingly focus on (gender-specific) barriers and pave the way for treatment in outpatient.

[Suicides among children, adolescents, and young adults during the COVID-19 pandemic - An analysis of police data from three German federal states]

OBJECTIVE

The COVID-19 pandemic severely affected young people, resulting in increased psychological distress and rising prevalence rates for mental disorders. There is concern that completed suicides have increased in addition to the observed increase in suicide attempts.

METHOD

The study is based on the police crime statistics (01/2017 to 12/2022) of three federal states in Germany, representing 13% of Germany's overall population. Suicide counts and rates for the child, teenage, adolescent, and young adult age groups were compared between the pre-pandemic and pandemic periods using chi-squared tests.

RESULTS

860 people under age 30 died from suicide. Suicide rates did not differ between the pre-pandemic and pandemic periods in any of the age groups studied.

CONCLUSION

So far, there has been no discernible increase in suicides among young Germans. Ongoing suicide monitoring is recommended.

Trend of suicide by self-immolation in a 13-year timeline: was the COVID-19 pandemic a potentially important stressor?

Introduction

Self-immolation is an uncommon way of attempting and committing a suicide, with a fatality rate of 80%. The risk factors in self-immolation victims vary depending on demographic characteristics, socio-economic and cultural factors as well as religious beliefs. Whether the COVID-19 pandemic was a potentially important stressor for self-immolation is still unknown, with insufficient studies examining this issue. Therefore, in this study, we aimed to examine the trend of self-immolation in a 13-year timeline, and the potential association of COVID-19 pandemic with the increase in the incidence and severity of self-immolation injuries in Serbia in 2021.

Materials and methods

The study included hospitalized patients due to intentional burns caused by self-immolation in the period from January 1, 2008 to December 31, 2021. Joinpoint regression analysis was used for the analysis of continuous linear trends of self-immolation cases with change points.

Results

While a rising trend was observed in the 2008-2013 time segment, followed by a decline in the upcoming 2013-2016 time segment, a significant increase reached its maximum during COVID-19 pandemic (2021), with annual percent change of 37.1% (p = 0.001). A significant increase in the median number of cases per year was observed during 2021 compared to the previous periods (7.5 vs. 2). Frequency of patients with a psychiatric diagnosis vs. those without a psychiatric diagnosis was significantly higher during than before the COVID-19 period (66.7 vs. 36.1%, p = 0.046).

Conclusion

In our study, a significant increase in the frequency of suicide attempts by self-immolation during COVID-19 pandemic was noticed. There was also an increased frequency of pre-existing psychiatric illness among patients during the pandemic period. With limited high-quality data available, the study adds to a rising body of evidence for assessment of outcomes of the pandemic on mental health and recognition of stressors for self-immolation.

The altered temporal properties of dynamic functional connectivity associated with suicide attempt in bipolar disorders

OBJECTIVE

The suicide risk in bipolar disorder (BD) is the highest among psychiatric disorders, and the neurobiological mechanism of suicide in BD remains unclear. The study aimed to investigate the underlying relevance between the implicated abnormalities of dynamic functional connectivity (FC) and suicide attempt (SA) in BD.

METHODS

We used the sliding window method to analyze the dynamic FC patterns from resting-state functional MRI data in 81 healthy controls (HC) and 114 BD patients (50 with SA and 64 with none SA). Then, the temporal properties of dynamic FC and the relationship between altered measures and clinical variables were explored.

RESULTS

We found that one of the five captured brain functional states was more associated with SA. The SA patients showed significantly increased fractional window and dwell time in the suicide-related state, along with increased number of state transitions compared with none SA (NSA). In addition, the connections within subcortical network-subcortical network (SubC-SubC), default mode network-subcortical network (DMN-SubC), and attention network-subcortical network (AN-SubC) were significantly changed in SA patients relative to NSA and HC in the suicide-related state. Crucially, the above-altered measures were significantly correlated with suicide risk.

CONCLUSIONS

Our findings suggested that the impaired dynamic FC within SubC-SubC, DMN-SubC, and AN-SubC were the important underlying mechanism in understanding SA for BD patients. It highlights the temporal properties of whole-brain dynamic FC could serve as the valuable biomarker for suicide risk assessment in BD.

Psychiatric profiles in suicidal attempters: Relationships with suicide behaviour features

BACKGROUND

Suicide constitutes a major health concern worldwide, being a significant contributor of death, globally. The diagnosis of a mental disorder has been extensively linked to the varying forms of suicidal ideation and behaviour. The aim of our study was to identify the varying diagnostic profiles in a sample of suicide attempters.

METHODS

A sample of 683 adults (71.3% females, 40.10±15.74 years) admitted at a hospital emergency department due to a suicide attempt was recruited. Latent class analysis was used to identify diagnostic profiles and logistic regression to study the relationship between comorbidity profile membership and sociodemographic and clinical variables.

RESULTS

Two comorbidity profiles were identified (Class I: low comorbidity class, 71.3% of attempters; Class II: high comorbidity class, 28.7% of attempters). Class I members were featured by the diagnosis of depression and general anxiety disorder, and low comorbidity; by contrast, the high comorbidity profile was characterized by a higher probability of presenting two or more coexisting psychiatric disorders. Class II included more females, younger, with more depressive symptoms and with higher impulsivity levels. Moreover, Class II members showed more severe suicidal ideation, higher number of suicide behaviours and a greater number of previous suicide attempts (p<.01, for all the outcomes), compared to Class I members.

CONCLUSIONS

Psychiatric profiles may be considered for treatment provision and personalized psychiatric treatment in suicidal attempters as well as tackle suicide risk.
