Risk of suicide and suicide-related events in subjects treated with antiseizure medications.

INTRODUCTION: In the United States, it is reported that 1.4% of the general population commits suicide. It has been postulated that antiseizure medications (ASMs) can lead to the development of suicidal ideation and suicidal behavior; however, this risk is still very low and has yet to be precisely established. AREAS COVERED: This narrative review evaluates the risk of suicide-related events (SREs) in subjects taking ASMs for various neurological disorders. Screening tools for suicidal ideation and suicidal behavior are also discussed. References for this article were found using PubMed/MEDLINE. EXPERT OPINION: Although some ASMs can be associated with SREs, this is not yet clearly established. The mechanisms involved in suicide risk in subjects taking ASMs are multifactorial. The bidirectional relationship between depression and epilepsy, as well as other associations, should be kept in mind when interpreting any impact of ASMs in PWE. Screening for SREs, close monitoring of subjects taking ASMs are the most appropriate strategies to minimize suicide risk. More efforts should be made to achieve accurate risk stratification through prognostic models that could be applied to subjects taking ASMs. Studies exploring the association between ASMs and suicide should consider ASMs individually and control for prior SREs.

Investigation of the trend and related factors of suicide attempts and suicide deaths in southeast Iran during 2018-2022.

Suicide is a major public health challenge worldwide with an increasing trend. Identifying risk factors for suicide attempts and suicide deaths may help find useful ways to prevent suicide. We aimed to determine the trend and related factors of suicide attempts and suicide deaths in Rafsanjan. This retrospective study included all suicide cases from 2018 to 2022 in Rafsanjan, a city in the southeast of Iran. The information was extracted from the suicide registration system of Rafsanjan University of Medical Sciences. Univariable and multivariable logistics regression models were used to investigate factors affecting suicide death. A total of 2039 cases of suicide, including 1932 cases (94.75%) of suicide attempts and 107 cases (5.25%) of suicide deaths were recorded during the study period. The frequency of suicide deaths and suicide attempts per 100,000 people increased in 2022 compared to 2018 in both genders. In the adjusted model, the odds of suicide deaths in males was 6.48 (95% CI 3.39-12.42) times higher than in females. Also, the odds of suicide deaths in unemployed subjects and housewives were 2.64 (95% CI 1.50-4.67) and 7.45 (95% CI 3.08-18.07) times higher than employed subjects respectively. Finally, people with education less than a diploma had 10.85 (95% CI 1.48-79.54) times higher odds of suicide deaths compared to people with university education. The present research showed that the pattern of suicide has been increasing since 2018, and we may see an upward trend in the coming years, which requires further investigation and preventive measures. Male gender, low education level, unemployment, and being a housewife were associated with the highest frequency of suicide death.

Suicide deaths and substance use in the Galician provinces between 2006 and 2020.

Background: Suicide is a serious public health problem that affects our entire country, including the Galician provinces. The aim of this research was to study the variation in completed suicide rates, between 2006 and 2020, in the different Galician provinces and their relationship with the consumption of addictive substances. Methods: Completed suicide data from the Spanish Office for National Statistics and the Institute of Legal Medicine of Galicia were analyzed with a Joinpoint regression model to determine time trends. The relationship between the variation in completed suicide rates with sociodemographic variables obtained from the Spanish Office for National Statistics and variables related to the consumption of substances obtained from the survey on alcohol and other drugs in Spain (EDADES) of the Government Delegation for the National Plan on Drugs was also analyzed. Results: The Joinpoint regression model did not reveal any point of significant change in the period studied for any Galician province. The following variables correlated positively with the variation in completed suicide rates in the Galician provinces: masculinity ratio, average age, daily alcohol consumption and daily illegal substance consumption. Conclusion: Applying preventive strategies on the daily consumption of alcohol and illegal substances would help reduce the rates of completed suicide in the Galician provinces.

Characteristics of Attempted and Completed Suicides During the COVID-19 Pandemic.

BACKGROUND: This study aimed to describe patients admitted for attempted or completed suicide during the COVID-19 pandemic. METHODS: A 1-year retrospective review was performed of adult patients admitted for attempted or completed suicide. RESULTS: Of the 30 patients included, most injuries involved firearms (37%) and cutting/piercing (30%). Sixty-three percent of patients presented with an Injury Severity Score ≥16, and 37% of injuries involved the head. Upon admission, an alcohol test was completed for 83% of patients, 56% of whom tested positive. Thirty percent of patients died from their injuries, with all but one involving a firearm. Most of those who survived to discharge (62%) were discharged to an inpatient behavioral health facility. DISCUSSION: The current study indicated a large proportion of suicides during the COVID-19 pandemic involved firearms and alcohol use. These findings point to the need for interventions aimed at preventing suicide and substance abuse during pandemic situations.

Why are Suicides With Unknown Cause the Most Important Reason for Suicide? A Retrospective Study.

This study will help in determining national suicide prevention strategies. Moreover, understanding the reasons for the lack of awareness about completed suicide will strengthen the measures to be taken in this regard. It was determined that the most important rate among the causes 48 419 completed suicide in Turkey in the years 2004 to 2019 was the 22 645 (46.76%) suicides of unknown cause and there was not enough information about the underlying causes. Suicide statistics data of the Turkish Statistical Institute (TUIK) between 2004 and 2019 were analyzed retrospectively in terms of geographical regions, gender, age groups and seasonality. Statistical analyses of the study were performed using the Statistical Package for Social Sciences for Windows (IBM SPSS version 25.0, Armonk, NY, USA) software. It was determined that the highest crude rate of suicide during 16 years was in the Eastern Anatolia region, the lowest rate was in the Marmara region, and the ratio of the number of female suicides with unknown cause to the number of male suicides was higher in Eastern Anatolia than in other regions, the rate of unknown crude suicide in both genders was highest in the under 15 age group, this rate decreased as the age progressed, the lowest rate was in women with unknown age, the effect of the season was observed in women with unknown cause, but not in men. Between 2004 and 2019, suicides with unknown cause were the most important reason for suicide. We think that there may be geographical, gender, age, seasonal, sociocultural and economic factors that may affect this, national suicide prevention and planning strategies will be insufficient unless this issue is adequately examined, and institutional structures should be established, including psychiatrists, where deep forensic investigations can be carried out.

Suicidality and epilepsy: A systematic review and meta-analysis.

Background: We aimed to evaluate the association between epilepsy and suicidality, including suicidal ideation, attempts and completed suicide. Methods: We systematically searched PubMed, Embase, Cochrane Online Library, and Clinicaltrials.gov from 1946 to June 21, 2021 and assessed the quality of the studies using the Newcastle-Ottawa Scale. We calculated the pooled OR and the crude rate for suicidal ideation, suicide attempts and completed suicide in patients with epilepsy (PWE). Results: We screened 2,786 studies and included 88 articles with 1,178,401 PWE and 6,900,657 participants as controls. Search terms included epilepsy and suicide. The pooled rates of suicidal ideation, suicide attempts and completed suicide in PWE were 19.73% (95% CI: 17.00-22.62%), 5.96% (95% CI: 4.82-7.20%), and 0.24% (95% CI: 0.11-0.42%), respectively. Compared to the control group, PWE were at a significantly higher risk of total suicidality (pooled OR, 2.60; 95%: 2.13-3.18), including suicidal ideation (pooled OR, 2.70; 95% CI, 2.21-3.30), suicide attempts (pooled OR, 2.74; 95% CI, 2.08-3.61) and completed suicide (pooled OR, 2.36; 95% CI, 1.45-3.83). Subgroup analyses showed significant differences in the subgroups of the measurement of suicidality. Conclusion: The rate of suicidal ideation, suicide attempts and completed suicide in PWE were about 19.73, 5.96, and 0.24%. And there was an increased risk of suicidality in PWE especially temporal lobe epilepsy and drug-resistant epilepsy. Clinicians need to be aware of this risk in PWE with early identification and prevention at the time of diagnosis.Protocol Registration: PROSPERO CRD42021278220.

Trends of completed suicide rates among Malaysian elderly between 1995 and 2020.

BACKGROUND: Suicide among the elderly has become a global public health concern. This study was carried out to determine the trend of completed suicide rates according to age, sex, and ethnicity and the suicidal methods among the elderly in Malaysia. METHODS: All suicide-related deaths in elderly aged 60 years and above from the Year 1995 to 2020 reported to the National Registration Department (NRD) were analyzed. Causes of death for suicide were coded based on the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10). The completed suicide rate was calculated by dividing the completed suicide number by the total elderly population for the respective year. RESULTS: Overall, the analysis of 1,600 suicide-related deaths was investigated over 26 years. Male was seen to be correlated with higher suicidal risk, with a male-female relative risk (RR) = 1.89 (95%CI:1.46,2.45). The risk of suicide was also found to be significantly higher for those aged 60 to 74 years old and Chinese, with RR = 4.26 (95%CI:2.94, 6.18) and RR = 5.81 (95%CI: 3.70, 9.12), respectively. Hanging was found to be a statistically significant suicide method (IRR:4.76, 95%CI:2.34,9.65) as compared to pesticide poisoning. The completed suicide rate was fluctuating over the years. CONCLUSIONS: In conclusion, it is believed that Malaysia's elderly suicide rate has reached an alarmingly high incidence. By identifying the crucial criteria of sociodemographic factors, the government and responsible agencies have the essential and additional information to put together a more effective strategy and approach to overcome the issue in the future.

Gender and age differences in suicide attempt: A large population study in the West of Iran.

Present study was to evaluate the relationship between suicide attempt, gender and age. We used all of suicide attempt entered in Hamadan Suicide Registry Program (2016-2017). Finding revealed that suicide attempt was lower among elderly patients. Using poison and self-immolation was more common in elder patients. Suicide attempt in females against males was higher in married. In males the higher rate of suicide attempt was in autumn, while in females was in summer. Using of drug was more frequent in females, while self-harm was more common in males. Gender and age are important risk factors of suicide attempts.

Attempted suicide: does lethality matter?

OBJECTIVES: To investigate whether high-lethality suicide attempters align to the demographic and clinical features observed in completed suicide in the national and international literature, and whether low-lethality attempters more closely align with the clinical profile of non-attempter ideators. METHODS: A retrospective chart review of adult suicide ideators and attempters presenting to an urban tertiary care hospital was performed. Suicide ideators (n = 50) and attempters (n = 50) were coded for variables including demographics and clinical characteristics (e.g. psychiatric diagnosis and previous suicide attempt). Method and lethality of suicide attempt were coded using the medical Lethality Rating Scale. RESULTS: High-lethality attempters were more likely to be younger in age than low-lethality attempters (p = 0.026) and ideators (p = 0.041). The lethality scores of suicide attempts were significantly inversely correlated with age (p = 0.017). CONCLUSIONS: Our study adds to the small but increasing body of literature investigating the characteristics of high-lethality suicide attempters and suggests younger adult age is a risk factor for a high-lethality attempt. Further understanding of this unique group would be aided by widespread agreement on the definition of a high-lethality suicide attempt and longitudinal studies of this cohort.

Changes in the pattern of suicides and suicide attempt admissions in relation to the COVID-19 pandemic.

The consequences of the current COVID-19 pandemic for mental health remain unclear, especially regarding the effects on suicidal behaviors. To assess changes in the pattern of suicide attempt (SA) admissions and completed suicides (CS) in association with the COVID-19 pandemic. As part of a longitudinal study, SA admissions and CS are systematically documented and analyzed in all psychiatric hospitals in Frankfurt/Main (765.000 inhabitants). Number, sociodemographic factors, diagnoses and methods of SA and CS were compared between the periods of March-December 2019 and March-December 2020. The number of CS did not change, while the number of SA significantly decreased. Age, sex, occupational status, and psychiatric diagnoses did not change in SA, whereas the percentage of patients living alone while attempting suicide increased. The rate and number of intoxications as a SA method increased and more people attempted suicide in their own home, which was not observed in CS. Such a shift from public places to home is supported by the weekday of SA, as the rate of SA on weekends was significantly lower during the pandemic, likely because of lockdown measures. Only admissions to psychiatric hospitals were recorded, but not to other institutions. As it seems unlikely that the number of SA decreased while the number of CS remained unchanged, it is conceivable that the number of unreported SA cases increased during the pandemic. Our data suggest that a higher number of SA remained unnoticed during the pandemic because of their location and the use of methods associated with lower lethality.

Rate and Causes of Suicide in Ilam: A Report of the Suicide Registry.

Objective: Suicide is one of the most important health problems in the world. Financial, academic, social, and environmental difficulties along with genetic, physical, and mental disorders affect suicide attempts. This study aimed to find risk factors for completed suicide in Ilam province according to the suicide registry in Ilam province. Method : This was a prospective study and was performed based on suicide case registration data, pre-determined checklist data, and death registration data in Ilam province from March 2019 to September 2020. Logistic regression models and the Chi-square test were used to determine the relationship between completed suicide and its risk factors. Results: Among 1,410 attempted suicides, 66 (4.7 %) were executed. Rate of completed suicides was higher in men (6.5%) compared to women (4.5%), (p = 0.005), age groups over 65 years (P < 0.001), retirees and farmers (P = 0.009), illiterate people (P < 0.001), villagers (P = 0.02), people motivated due to physical problems (P = 0.016), suicide by physical methods (P < 0.001) and self-immolation (P < 0.001). Logistic regression showed that incidence of completed suicide was significantly higher in the age group over 65 years, illiterate people, people using physical methods, villagers, and men. Multivariate logistic regression also showed that men and individuals using physical methods of suicide were significantly more successful in suicide. Conclusion: Men, the elderly, illiterates, villagers, and people who used physical suicide methods were in high-risk groups. Despite lower prevalence of suicide, a higher rate of completed suicide was demonstrated. To decrease completed suicide rates, we must pay attention to these groups.

Relationship of religion with suicidal ideation, suicide plan, suicide attempt, and suicide death: a meta-analysis.

BACKGROUND: Suicide is a significant public health problem and one of the leading causes of death worldwide. The effect of religion on suicidal behaviors (i.e., ideation, plan, attempt, and death) is an important issue worthy of consideration. METHODS: Major electronic databases, including MEDLINE, Web of Science, and Scopus, were searched for the articles published until 26 April 2021. Reference lists were also screened. Observational studies addressing the associations between religion and suicidal behaviors were also examined. Between-study heterogeneity was investigated using the χ2, τ2, and I2 statistics. The probability of publication bias was explored using the Begg and Egger tests, as well as trim-and-fill analysis. The effect size was expressed as odds ratio (OR) with 95% confidence intervals (CIs) using a random-effects model. RESULTS: Out of 11 389 identified studies, 63 articles were eligible, involving 8,053,697 participants. There was an inverse association between religion and suicidal ideation OR  =  0.83 (95% CI: 0.78, 0.88; P < 0.001), suicidal plan OR  =  0.93 (95% CI: 0.83, 1.04; P =  0.200), suicide attempt OR  =  0.84 (95% CI: 0.79, 0.89; P < 0.001), and completed suicide OR  =  0.31 (95% CI: 0.14, 0.72; P =  0.006). There was a no evidence of publication bias. CONCLUSIONS: The results of this meta-analysis support the notion that religion can play a protective role against suicidal behaviors. Nonetheless, the effect of religion on suicidal behaviors varies across countries with different religions and cultures. Although this association does not necessarily imply causation, an awareness of the relationship between religion and suicide risk can be of great help in suicide prevention policies and programs.

Healthcare Utilization 12 Months Prior to Fatal and Non-fatal Suicidal Behaviour in Cape Town, South Africa.

The purpose of this study was to characterize healthcare use for general care and mental health one year before suicidal behavior among individuals with fatal and non-fatal suicidal behavior (NFSB) in Cape Town, South Africa. We linked electronic health records of 484 participants from a case series of 93 completed suicides on whom forensic autopsies were performed at a mortuary in Cape Town, between August 2014 and January 2016; and 391 patients admitted to hospital following NFSB between June 2014 and March 2015, and between August 2015 and August 2017. Time from last healthcare visit to date of suicidal behavior (fatal or non-fatal) was calculated, and Kaplan Meier curves were used to compare the differences by psychiatric diagnoses and study group. Overall, 64.5% of completed suicides and 65.9% of NFSB patients sought general healthcare in the year before suicidal behavior. Most of these visits occurred at hospital outpatient clinics (40.8%) and primary healthcare facilities (31.3%). The prevalence of preexisting psychiatric diagnoses and the use of mental healthcare services was lower for individuals who completed suicide compared to NFSB patients. Common reasons for a healthcare visit among individuals who completed suicide were chronic disease and assault; and psychiatric illness (depression, bipolar, and/or substance use disorders), chronic disease and HIV among NFSB patients. A large proportion of individuals with fatal and NFSB interacted with the healthcare system before suicidal behavior. These findings suggest opportunities for suicide prevention at primary healthcare facilities, antiretroviral treatment centers and emergency departments.HIGHLIGHTSHealthcare access is common among individuals with fatal and NFSB in the year before suicidal behavior.The prevalence of mental disorder diagnoses is higher among NFSB patients than among individuals who completed suicide.A greater proportion of NFSB patients accessed mental healthcare services compared to individuals who completed suicide.

Completed Suicide Linked to the COVID-19 Pandemic by Using the Psychological Autopsy Method in Sibiu County, Romania: Case Series and Literature Review.

The COVID-19 pandemic is associated with suicide, as some data suggests. Our study aims to investigate the emergence of eleven completed suicide cases suspected to be linked to the COVID-19 pandemic during the restrictive measures imposed by the Romanian government, and to identify the consequences of mental health, suicidal motivation, and behavioral changes. To this end, we analyzed the deceased's medical records and applied the psychological autopsy method to the relatives/caregivers of the deceased for a suicidal investigation history, within conducted free-flow discussions. To highlight behavioral changes that occurred in the distant antecedents as well as immediately before the suicidal act, we used two sets of closed questions comprised of fifteen alarm signs, including depressive and/or anxiety symptoms. Our results showed that a deterioration of the mental status, especially concerning depressive and anxiety symptoms, was evident in people without or with pre-existing psychiatric pathology. The suicidal motivation proved to be complex including, in addition to the SARS-CoV-2 infection, social and economic consequences of the COVID-19 pandemic. We noted an intensification of the investigated alarm signs and even the emergence of new warning signs in the recent antecedents. Based on our findings, we reaffirmed the important role of the psychological autopsy method in suicide investigation, proving that it can detect the specific impact of the COVID-19 pandemic on people prone to suicide. This impact can be psycho-emotional, social, and/or economical, and thus we can state that the COVID-19 pandemic and its consequences can be, at least, a triggering factor that enhances completed suicide risk. Further studies are needed in this particular area because correlations between the COVID-19 pandemic and completed suicide do not appear to be accidental.

Risks of suicide among family members of suicide victims: A nationwide sample of South Korea.

Objective: Identifying the risks of completed suicide in suicide survivors is essential for policies supporting family members of suicide victims. We aimed to determine the suicide risk of suicide survivors and identify the number of suicides per 100,000 population of suicide survivors, bereaved families of traffic accident victims, and bereaved families with non-suicide deaths. Methods: This was a nationwide population-based cohort study in South Korea. The data were taken from the Korean National Health Insurance and Korea National Statistical Office between January 2008 and December 2017. The relationship between the decedent and the bereaved family was identified using the family database of the National Health Insurance Data. Age and gender were randomly matched 1:1 among 133,386 suicide deaths and non-suicide deaths. A proportional hazard model regression analysis was conducted after confirming the cumulative hazard using Kaplan-Meier curves to obtain the hazard ratio (HR) of completed suicide in suicide survivors. Results: Using 423,331 bereaved families of suicide victims and 420,978 bereaved families of non-suicide deaths as the control group, HR of completed suicide in suicidal survivors was found to be 2.755 [95% confidence limit (CL): 2.550-2.977]. HR for wives committing suicide after husbands' suicide was 5.096 (95% CL: 3.982-6.522), which was the highest HR among all relationships with suicide decedents. The average duration from suicide death to suicide of family members was 25.4 months. Among suicide survivors, the number of suicides per 100,000 people was 586, thrice that of people in bereaved families of traffic accident victims and in bereaved families of non-suicide deaths. Conclusion: The risk of completed suicide was three times higher in suicide survivors than in bereaved families with non-suicide deaths, and it was highest in wives of suicide decedents. Thus, socio-environmental interventions for suicidal survivors must be expanded.

Suicidality in Patients With Epilepsy: Why Should Neurologists Care?

Suicidality is a relatively common comorbidity in patients with epilepsy (PWE). Population-based studies have revealed lifetime prevalence rates of 25% of suicidal ideation (SI). In addition, PWE without comorbid psychiatric disorders has two to three higher risk of committing suicide and this risk increases by 12- to 32-fold in the presence of various psychiatric disorders. Risk factors are multiple and include socio-demographic, genetic, age and gender, and psychiatric comorbidities. Among the latter, mood, anxiety, and psychotic disorders have been found to be common risk factors for suicidality in PWE, but iatrogenic causes resulting from pharmacotherapy with antiseizure drugs or epilepsy surgery can also cause SI and behavior. Suicidality and epilepsy have a complex bidirectional relation, whereas PWE are at increased risk of suicidality and vice-versa. Common pathogenic mechanisms operant in both conditions may explain this bidirectional relation. SI can be easily identified in outpatient epilepsy clinics with screening instruments and can be treated and thus prevent its escalation to suicidal attempts and completed suicide. The aim of this manuscript is to review these data in detail.

Time series analysis of suicide from a monthly perspective in the south of Brazil: an ecological study.

INTRODUCTION: Suicide is the cause of death of almost 800 thousand people worldwide every year. In Brazil, Rio Grande do Sul is one of the states with the highest suicide rates. This study aimed to assess whether there is a significant monthly time pattern of suicide in Rio Grande do Sul, by gender and age ranges, and whether suicide characteristics in the state are coherent with findings from previous studies. METHODS: All data were collected from official secondary sources maintained by the national Brazilian and Rio Grande do Sul governments, covering a period from 2015 to 2019. Data included suicide deaths and population, divided by gender and age range. Sum totals, frequencies, odds ratios, and time series analyses were performed. RESULTS: From 2015 to 2019, 6,287 people committed suicide in Rio Grande do Sul. Most of them were men and the most prevalent age band was from 50 to 59 years old. Men had higher suicide rates then women in all age ranges (p < 0.001) and in all months of the year, with an approximately 4-fold higher risk of committing suicide when compared to women. Men had a trending peak of suicide in January and December (p < 0.001), whereas women's suicide rates peaked in March and December (p = 0.001). CONCLUSION: There are monthly time trends and seasonal patterns of suicide rates in Rio Grande do Sul, varying by gender and age range. Gender differences occurred mainly in the first three months of the year, and the age pattern was more evident among individuals aged 60 years or older.

Introduction: Suicide is a major public health problem. The objective of this study is to analyze the demographic, clinical and toxicological characteristics and the mechanisms of suicide in young people and middle-aged adults.MethodRetrospective population study of completed suicide in subjects aged 14-55 who were subjected to a forensic autopsy in Bizkaia between 2016-2018.Results272 suicides were recorded. The global incidence was 7.8/100.00 inhabitants/year. 127 were 14-55 years old. The rate was 3 times higher in men and increased with age. In 72%, some clinical risk factor was collected, mainly mental disorders (59%): mood disorders (23%), substance abuse (20.5%) and psychotic disorders (14%). 38% of addicts had another mental disorder. Physical illness (23%) and suicide attempt (20.5%) were also relevant factors. 41% were positive for alcohol and/or illicit drugs: ethanol (22%), cannabis (16%), cocaine (11%) and amphetamine (8%). This percentage was 79% in substance addicts. Substance abuse disorders (25% vs. 6.5%; p = 0.03) and presence of alcohol and/or drugs (49% vs. 16%; p = 0.001) were more prevalent in men. The most commonly used methods were fall from heights (35%) and hanging (31%).ConclusionsThe incidence of suicide in Bizkaia is lower than the European average. Suicide is a complex problem associated with demographic and clinical factors (mainly depressive and substance abuse disorders) and recent use of alcohol and illicit drugs. Prospective multidisciplinary and multicenter researches are required in order to identify risk factors and to guide preventive measures. (AU)
