Although suicide bereavement is associated with suicide and self-harm, evidence regarding mechanisms is lacking. We investigated whether depression and substance use (alcohol and/or other drugs) explain the association between partner suicide bereavement and suicide.

Linkage of nationwide, longitudinal data from Denmark for the period 1980–2016 facilitated a comparison of 22 668 individuals exposed to bereavement by a partner's suicide with 913 402 individuals bereaved by a partner's death due to other causes. Using causal mediation models, we estimated the degree to which depression and substance use (considered separately) mediated the association between suicide bereavement and suicide.

Suicide-bereaved partners were found to have a higher risk of suicide (HRadj = 1.59, 95% CI 1.36–1.86) and of depression (ORadj 1.16, 95% CI 1.09–1.25) when compared to other-bereaved partners, but a lower risk of substance use (ORadj 0.83; 95% CI 0.78–0.88). An increased risk of suicide was found among any bereaved individuals with a depression diagnosis recorded post-bereavement (ORadj 3.92, 95% CI 3.55–4.34). Mediation analysis revealed that depression mediated 2% (1.68%; 95% CI 0.23%–3.14%; p = 0.024) of the association between suicide bereavement and suicide in partners when using bereaved controls.

Depression is a partial mediator of the association between suicide bereavement and suicide. Efforts to prevent and optimize the treatment of depression in suicide-bereaved people could reduce their suicide risk. Our findings might be conservative because we did not include cases of depression diagnosed in primary care. Further work is needed to understand this and other mediators.

Little is known about when youth may be at greatest risk for attempting suicide, which is critically important information for the parents, caregivers, and professionals who care for youth at risk. This study used adolescent and parent reports, and a case-crossover, within-subject design to identify 24-hour warning signs (WS) for suicide attempts.

Adolescents (N = 1094, ages 13 to 18) with one or more suicide risk factors were enrolled and invited to complete bi-weekly, 8–10 item text message surveys for 18 months. Adolescents who reported a suicide attempt (survey item) were invited to participate in an interview regarding their thoughts, feelings/emotions, and behaviors/events during the 24-hours prior to their attempt (case period) and a prior 24-hour period (control period). Their parents participated in an interview regarding the adolescents’ behaviors/events during these same periods. Adolescent or adolescent and parent interviews were completed for 105 adolescents (81.9% female; 66.7% White, 19.0% Black, 14.3% other).

Both parent and adolescent reports of suicidal communications and withdrawal from social and other activities differentiated case and control periods. Adolescent reports also identified feelings (self-hate, emotional pain, rush of feelings, lower levels of rage toward others), cognitions (suicidal rumination, perceived burdensomeness, anger/hostility), and serious conflict with parents as WS in multi-variable models.

This study identified 24-hour WS in the domains of cognitions, feelings, and behaviors/events, providing an evidence base for the dissemination of information about signs of proximal risk for adolescent suicide attempts.

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.

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.

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.

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.

Suicide is a major public health problem and a cause of premature mortality. With a view to prevention, a great deal of research has been devoted to the determinants of suicide, focusing mostly on individual risk factors, particularly depression. In addition to causes intrinsic to the individual, the social environment has also been widely studied, particularly social isolation. This paper examines the social dimension of suicide etiology through a review of the literature on the relationship between suicide and social isolation.

Medline searches via PubMed and PsycINFO were conducted. The keywords were “suicid*” AND “isolation.”

Of the 2,684 articles initially retrieved, 46 were included in the review.

Supported by proven theoretical foundations, mainly those developed by E. Durkheim and T. Joiner, a large majority of the articles included endorse the idea of a causal relationship between social isolation and suicide, and conversely, a protective effect of social support against suicide. Moreover, the association between suicide and social isolation is subject to variations related to age, gender, psychopathology, and specific circumstances. The social etiology of suicide has implications for intervention and future research.

Correlations between neutrophil/lymphocyte, platelet/lymphocyte, and monocyte/lymphocyte ratios (NLR, PLR, and MLR, respectively) and psychopathological and clinical variables in the context of mood disorders are increasingly emerging in international scientific literature, being the former one of the most studied. The estimation of suicidal risk associated to affective disorders could benefit from such rapidly and easily available biomarker of inflammation, if significant in this regard.

The present review would like to focus on any existing correlations between NLR and suicidal risk in patients with mood disorders.

We sourced articles on the topic found in major scientific literature databases, combining the keywords “neutrophil/lymphocyte ratio”, “NLR”, “mood disorders”, “major depressive disorder”, “bipolar disorder” and “suicide risk”.

There are congruent findings of significantly higher NLR values in depressed patients attempting suicide than in depressed patients with no suicidal behaviors or healthy controls. In addition, violent means appear typical in this subgroup of depressed suicidal patients, suggesting that patients with higher levels of NLR are at risk of attempting suicide and to be successful in self-harming. Similar results have been found in patients with bipolar disorder, showing a positive correlation between NRL and suicide risk, evaluated by the Suicide Behaviors Questionnaire-Revised (SBQ-R). Moreover, in patients with a positive family history for suicide attempts, NRL was found to be a significant positive predictor of suicide risk.

These findings, although limited, support the notion that NLR might be a useful marker for suicide vulnerability in both BD and MDD patients.

Previous research has highlighted the importance of understanding which psychosocial factors distinguish between those with suicide thoughts compared to those who attempt suicide. This study aims to investigate these distinguishing factors further within an ideation-to-action framework and to explore sex differences in suicide risk.

Participants (n = 7546, aged 16+) were from the cross-sectional Adult Psychiatric Morbidity Survey (APMS; 2014) of England. Face-to-face and self-completion questionnaires assessed lifetime suicidal ideation, lifetime suicide attempts, demographic characteristics, life experiences, social support, health and mental illness. Multinomial logistic regression examined factors differentiating between those with suicidal ideation only and suicide attempt histories (with or without suicidal ideation) in men and women.

Overall men were less likely to report suicidal thoughts and attempts, compared to females. More factors differentiated between suicidal thoughts and attempts in women compared to in men; these included hospital admission for mental illness, below degree level qualifications, being single and childhood adversity. In men, factors which significantly differentiated between suicidal thoughts and attempts included self-report of professional diagnosis of mental illness and childhood adversity. Higher levels of social support were associated with being in the suicidal thoughts group v. in the attempts group in men.

This study identified some key differences between men and women in factors associated with suicide attempts compared to suicidal thoughts. The findings support the use of the ideation-to-action framework to investigate sex differences in suicidal behaviour. Future research should examine the extent to which these factors are associated with suicide risk over time.

Although several authors have investigated the relationship between demoralization, insight, and suicide risk, the role of these factors in determining suicide risk in patients with psychiatric disorders is still unclear [Berardelli et al., 2019; Costanza et al., 2020].

The main aim of this study was therefore to determine whether suicide risk was associated with better insight and worse demoralization in a sample of 100 adult psychiatric inpatients.

The study was performed on 100 psychiatric hospitalized adult patients consecutively enrolled between January 2019 and April 2020 at psychiatric units of Sant’Andrea Medical Center, Sapienza University of Rome. The Columbia Suicide Severity Rating Scale (C-SSRS) was used to assess suicide risk, Demoralization was assessed using the Demoralization Scale (DS) [Kissane et al., 2004] and for the assessment of insight we used the The Insight Scale (IS).

Only age was significantly associated with higher suicide risk (χ2=9.07, p<0.01). The variable mood disorder was significantly associated with higher suicide risk (χ22=7.50, p<0.05). Non-suicidal self-harm behaviors in the last 3 months (χ2=5.89, p<0.05) and lifetime suicide attempts (χ2=21.80, p<0.001) were significantly associated with higher suicide risk. Only the insight-high dimension (χ2=8.01, p<0.01) and lifetime suicide attempts (χ2=12.33, p<0.001) were significantly associated with higher suicide risk.

Our results don’t confirm the role of demoralization in suicide risk. In our sample of patients, only high insigth of illness and other psychological variables are involved in suicide risk.

Patients with schizophrenia have increased cardiovascular and suicide risk. Metabolic syndrome (MetS) is widespread in this group, however, there are no unambiguous data on the relationship between the separate components of metabolic syndrome and suicide risk.

To examine the relationship between the separate components of the MetS and suicide risk in patients with schizophrenia.

We examined 64 patients with schizophrenia. All patients received antipsychotic therapy in doses comparable in chlorpromazine equivalents. We measured serum levels of lipids, glucose and insulin. The visceral fat level was determined through the non-invasive bioimpedance analysis with an “Omron BF508” scale and body composition monitor. Suicide risk was assessed using Beck Hopelessness Inventory. There were identified two groups of examined: with MetS and without MetS. In both groups were distinguished two subgroups: patients with normal range of hopelessness and patients with mild and moderate hopelessness. Subgroups were compared among themselves for a number of anthropometric, biochemical and clinical indicators. Statistical analysis was conducted using Mann-Whitney U-test. Reliability level corresponded to p<0.05. This study was supported by a grant from the Russian Science Foundation 18-15-00011.

Waist circumference, body weight and BMI in subgroup with normal hopelessness range in the group of patients with MetS were significantly higher (figure 1).

We were able to establish a negative relationship between the waist circumference, body weight and BMI with suicide risk in schizophrenia patients. It can be assumed that adipose tissue can play a “protective” role in the suicidal behavior of schizophrenia patients.

Suicide is an international public health problem and a leading cause of death for youth and adults, worldwide. Prevention efforts in health care systems create opportunities for identifying medical patients with occult suicidality. Detecting suicide risk among patients in medical settings can be a challenge, but successful suicide risk screening programs have been demonstrated in hospital settings.

This presentation will discuss how a suicide risk screening tool that was developed for the pediatric emergency department was tested and then implemented in other medical settings in order to leverage healthcare providers as partners in combating the public health crisis of youth suicide..

Implementation and quality improvement projects in various medical settings that have adapted the ASQ will be described. Effective management of pediatric patients that screen positive for suicide risk and how mental health clinicians can best be utilized in efficient ways will also be discussed.

Average time to administer the ASQ was 20 seconds. Positive screen rates across ED, inpatient and outpatient settings ranging from 2-14% equating to one additional psychiatric consultation per week. The ASQ Toolkit was developed to help medical providers implement screening including scripts for nurses, flyers for parents and a brief suicide safety assessment (ASQ BSSA) to operationalize next steps for patients at risk.

The medical setting is a key venue for youth suicide risk detection and linking patients with effective interventions. Mental health clinicians have a role in guiding non-mental health providers in the identification and management of patients found to be at risk.

(1) To delineate whether cognitive flexibility and inhibitory ability are neurocognitive markers of passive suicidal ideation (PSI), an early stage of suicide risk in depression and (2) to determine whether PSI is associated with volumetric differences in regions of the prefrontal cortex (PFC) in middle-aged and older adults with depression.

Cross-sectional study.

University medical school.

Forty community-dwelling middle-aged and older adults with depression from a larger study of depression and anxiety (NIMH R01 MH091342-05 PI: O’Hara).

Psychiatric measures were assessed for the presence of a DSM-5 depressive disorder and PSI. A neurocognitive battery assessed cognitive flexibility, inhibitory ability, as well as other neurocognitive domains.

The PSI group (n = 18) performed significantly worse on cognitive flexibility and inhibitory ability, but not on other neurocognitive tasks, compared to the group without PSI (n = 22). The group with PSI had larger left mid-frontal gyri (MFG) than the no-PSI group. There was no association between cognitive flexibility/inhibitory ability and left MFG volume.

Findings implicate a neurocognitive signature of PSI: poorer cognitive flexibility and poor inhibitory ability not better accounted for by other domains of cognitive dysfunction and not associated with volumetric differences in the left MFG. This suggests that there are two specific but independent risk factors of PSI in middle- and older-aged adults.

The United Nations warned of COVID-19-related mental health crisis; however, it is unknown whether there is an increase in the prevalence of mental disorders as existing studies lack a reliable baseline analysis or they did not use a diagnostic measure. We aimed to analyse trends in the prevalence of mental disorders prior to and during the COVID-19 pandemic.

We analysed data from repeated cross-sectional surveys on a representative sample of non-institutionalised Czech adults (18+ years) from both November 2017 (n = 3306; 54% females) and May 2020 (n = 3021; 52% females). We used Mini International Neuropsychiatric Interview (MINI) as the main screening instrument. We calculated descriptive statistics and compared the prevalence of current mood and anxiety disorders, suicide risk and alcohol-related disorders at baseline and right after the first peak of COVID-19 when related lockdown was still in place in CZ. In addition, using logistic regression, we assessed the association between COVID-19-related worries and the presence of mental disorders.

The prevalence of those experiencing symptoms of at least one current mental disorder rose from a baseline of 20.02 (95% CI = 18.64; 21.39) in 2017 to 29.63 (95% CI = 27.9; 31.37) in 2020 during the COVID-19 pandemic. The prevalence of both major depressive disorder (3.96, 95% CI = 3.28; 4.62 v. 11.77, 95% CI = 10.56; 12.99); and suicide risk (3.88, 95% CI = 3.21; 4.52 v. 11.88, 95% CI = 10.64; 13.07) tripled and current anxiety disorders almost doubled (7.79, 95% CI = 6.87; 8.7 v. 12.84, 95% CI = 11.6; 14.05). The prevalence of alcohol use disorders in 2020 was approximately the same as in 2017 (10.84, 95% CI = 9.78; 11.89 v. 9.88, 95% CI = 8.74; 10.98); however, there was a significant increase in weekly binge drinking behaviours (4.07% v. 6.39%). Strong worries about both, health or economic consequences of COVID-19, were associated with an increased odds of having a mental disorder (1.63, 95% CI = 1.4; 1.89 and 1.42, 95% CI = 1.23; 1.63 respectively).

This study provides evidence matching concerns that COVID-19-related mental health problems pose a major threat to populations, particularly considering the barriers in service provision posed during lockdown. This finding emphasises an urgent need to scale up mental health promotion and prevention globally.

Suicide risk is greatly increased in schizophrenia. Our study aim was to investigate interactional factors related to the recognition of suicide risk in patients with schizophrenia.

This case-control study focused on 66 schizophrenia patients who had committed suicide Study methods included in-depth interviews of next of kin and interviews of patients that had been saved from suicide and perfect information and statistics were extracted from patient's files and documents in fatemi hospital and analyzed by chi-square.

Studies show the most prevalence of disease is in male, citizens, single persons, uncaptioned and the average age was in the mid-thirties. Most participants had an under high school diploma, (56/1%). Almost 60/6% of the sample had a history of a previous depression, undifferentiated type of schizophrenia, previous anti socials acts (56/1%) According to the findings most participants (81/8%) had no precedence of being imprisoned. we survey the declared assumptions of the research and study the presence of any relation or lack of it between variable factors

Our findings suggest Prevention of suicide in schizophrenia is likely to result from treatment of affective symptoms, improving adherence to treatment, and maintaining special vigilance in patients with risk factors,

Restricting access to lethal means is an effective suicide prevention strategy. However, there is little discussion in the literature about the potential contribution of prescribing practices on discharge from inpatient psychiatric care (which has been established as a high-risk period for suicide) to suicide deaths by overdose of prescribed medication. This study aimed to assess the quantity, toxicity and potential lethality of psychotropic medication being prescribed on discharge from psychiatric care to those with and without indices of suicidality.

Patient demographic, clinical and prescription data were collected from 50 randomly selected charts following discharge from inpatient psychiatric care. Psychotropic medications (dose × duration) on discharge were converted to their equivalent doses of neuroleptics, antidepressants and anxiolytics to rate toxicity and potential lethality, using the Maudsley Prescribing Guidelines. Mood stabilizing medications were also documented.

39% of prescriptions analysed contained toxic and potentially fatal doses of either neuroleptic or antidepressant equivalent medication.

Patient discharge from inpatient psychiatric care presents a golden opportunity to moderate access to potentially fatal psychotropic medication. Iatrogenic provision of lethal means for suicide during a period of increased risk and in a group at increased suicide risk may impact suicide prevention efforts and requires further in-depth research. Current prescribing practices may be a missed opportunity to intervene in this regard.

The interactive effect of personal factors and social factors upon suicide risk is unclear. We conducted prospective cohort study to investigate whether the impact of the economic crisis in 1997–1998 upon suicide risk differed according to Neuroticism and Psychoticism personality traits.

The Miyagi Cohort Study in Japan with a follow-up for 19 years from 1990 to 2008 has 29 432 subjects aged 40–64 years at baseline who completed a questionnaire about various health habits and the Japanese version of the Eysenck Personality Questionnaire – Revised Short Form in 1990.

The suicide mortality rate increased from 4.6 per 100 000 person-years before 1998 to 27.8 after 1998. Although both Neuroticism and Psychoticism were significantly associated with an increased risk of mortality during the whole period from 1990 to 2008, the impact of the economic crisis upon suicide risk differed between the Neuroticism and Psychoticism personality traits. Compared with the lowest category, the hazard ratios (HRs) for the highest Neuroticism increased from 0.66 before 1998 to 2.45 after 1998. On the other hand, the HRs for the highest Psychoticism decreased from 7.85 before 1998 to 2.05 after 1998.

The impact of the 1997–1998 economic crisis upon suicide risk differed according to personality. Suicide risk increased among these with higher Neuroticism after the economic crisis, but this was not the case for other personality subscales.
