Suicide risk and suicide method in patients with personality disorders

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.

Suicidal behavior across a broad range of psychiatric disorders

Suicide is a leading cause of death worldwide. In 2020, some 12.2 million Americans seriously contemplated suicide, 3.2 million planned suicide attempts, and 1.2 million attempted suicide. Traditionally, the approach to treating suicidal behavior (SB) has been to treat the "underlying" psychiatric disorder. However, the number of diagnoses associated with SB is considerable. We could find no studies describing the range of disorders reported to be comorbid with SB. This narrative review summarizes literature documenting the occurrence of SB across the lifespan and the full range of psychiatric diagnoses, not only BPD and those that comprise MDE, It also describes the relevance of these observations to clinical practice, research, and nosology. The literature searches contained the terms "suicid*" and each individual psychiatric diagnosis and identified 587 studies. We did not include case reports, case series, studies only addressing suicidal ideation or non-suicidal self-injury (NSSI), studies on self-harm, not distinguishing between SB and NSSI and studies that did not include any individuals that met criteria for a specific DSM-5 diagnosis (n = 366). We found that SB (suicide and/or suicide attempt) was reported to be associated with 72 out of 145 diagnoses, although data quality varied. Thus, SB is not exclusively germane to Major Depressive Episode (MDE) and Borderline Personality Disorder (BPD), the only conditions for which it is a diagnostic criterion. That SB co-occurs with so many diagnoses reinforces the need to assess current and past SB regardless of diagnosis, and supports the addition of charting codes to the DSM-5 to indicate current or past SB. It also comports with new data that specific genes are associated with SB independent of psychiatric diagnoses, and suggests that SB should be managed with specific suicide prevention interventions in addition to treatments indicated for co-occurring diagnoses. SB diagnostic codes would help researchers and clinicians document and measure SB's trajectory and response to treatment over time, and, ultimately, help develop secondary and tertiary prevention strategies. As a separate diagnosis, SB would preclude situations in which a potentially life-threatening behavior is not accounted for by a diagnosis, a problem that is particularly salient when no mental disorder is present, as is sometimes the case.

Personality disorder and mild traumatic brain injury

Mild traumatic brain injury (mTBI) poses risk to the neurocognitive, emotional, and financial well-being of affected individuals. While aggression and impulsivity have been examined in relation to mTBI, little work has been done to evaluate the relationship between history of mTBI and personality disorder (PD). The authors examined the associations between history of mTBI and PD in a control group without history of mTBI (N = 1189) and individuals with history of mTBI (N = 267). Results demonstrated that any PD diagnosis is a significant risk factor for mTBI (p < 0.001). Cluster B diagnoses, particularly borderline and antisocial PD, were independently significant risk factors for mTBI. These data suggest a role for screening for a history of mTBI in patients with PDs and associated traits.

Pre-Existing Medical Conditions: A Systematic Literature Review of a Silent Contributor to Adult Drowning

Medical conditions can increase drowning risk. No prior study has systematically reviewed the published evidence globally regarding medical conditions and drowning risk for adults. MEDLINE (Ovid), PubMed, EMBASE, Scopus, PsycINFO (ProQuest) and SPORTDiscus databases were searched for original research published between 1 January 2005 and 31 October 2021 that reported adult (≥15 years) fatal or non-fatal drowning of all intents and pre-existing medical conditions. Conditions were grouped into the relevant International Classifications of Diseases (ICD) codes. Eighty-three studies were included (85.5% high-income countries; 38.6% East Asia and Pacific region; 75.9% evidence level III-3). Diseases of the nervous system (n = 32 studies; 38.6%), mental and behavioural conditions (n = 31; 37.3%) and diseases of the circulatory system (n = 25; 30.1%) were the most common categories of conditions. Epilepsy was found to increase the relative risk of drowning by 3.8 to 82 times, with suggested preventive approaches regarding supervised bathing or showering. Drowning is a common suicide method for those with schizophrenia, psychotic disorders and dementia. Review findings indicate people with pre-existing medical conditions drown, yet relatively few studies have documented the risk. There is a need for further population-level research to more accurately quantify drowning risk for pre-existing medical conditions in adults, as well as implementing and evaluating population-level attributable risk and prevention strategies.

How Did the COVID-19 Pandemic Affect the Use of Emergency Medical Services by Patients Experiencing Mental Health Crises?

The COVID-19 pandemic and its resulting social restrictions have significant implications for mental health. The objective of this study was to determine the monthly trends and types of patients experiencing a mental health crisis (MHC) who used emergency medical services (EMSs) before and during the COVID-19 pandemic. A retrospective observational study was conducted using EMS data. During the study period, 8577 patients used EMSs for MHCs. EMS dispatches for MHCs and suicide completion after the COVID-19 pandemic were decreased by 12.4% and 12.7%, respectively, compared to those before the COVID-19 pandemic. Segmented regression analysis found that the number of patients per month was 6.79 before the COVID-19 pandemic. The number decreased to 4.52 patients per month during the COVID-19 pandemic, although the decrease was not statistically significant. The monthly number of patients experiencing an MHC decreased during strict social distancing measures but increased during relaxed social distancing measures. The percentage of hanging increased from 14.20% before the COVID-19 pandemic to 14.30% (p = 0.03) during the COVID-19 pandemic, whereas the percentages of jumping (from 15.55% to 15.28%, p = 0.01) and self-harm by smoke (from 4.59% to 3.84%, p < 0.001) during the COVID-19 pandemic were decreased compared to those before COVID-19. However, the effect size for the above findings was small (below 0.20). More than 25% of the patients experiencing an MHC who used EMSs refused to transfer to the ED over both study periods (26.49% in the pre-COVID-19 period and 28.53% in the COVID-19 period). The COVID-19 pandemic and social restrictions seemed to have some effects on the use of EMSs by MHC patients. Hanging is mainly performed indoors and is not found easily if social distancing persists, and a patient experiencing an MHC who refuses to be transferred could potentially attempt suicide. Subsequent studies should be performed to determine whether these findings are temporary during the COVID-19 pandemic or whether they will show different aspects after the COVID-19 pandemic.

Using Pathological Traits for the Assessment of Suicide Risk: A Suicide Indicator Proposal for the Dimensional Clinical Personality Inventory 2

This study aimed to investigate the discriminative capacity of IDCP-2 factors to identify people with suicide risk. Moreover, we are providing a suicide total score for IDCP-2. Participeted 346 people aged between 18 and 72 years who responded to ASIQ, IDCP-2, and PID-5. We divided participants into three groups: low-risk group moderate-risk and high-risk group. We conducted mean comparisons, linear regression analysis, and ROC curve verification. The IDCP-2 factors were able to discriminate between the groups, with the high-risk presenting the highest means. The regression indicated Self-devaluation and Hopelessness as variables with a significant single contribution in explaining suicidal behavior. Suicide risk indicators demonstrated adequate performance in identifying people according to the risk group. Our findings indicate that the IDCP-2 factors can discriminate groups of people according to suicidal behavior. Besides, the index developed showed sensitivity in the identification of people who reported attempted suicide.   How to cite this article: Gonçalves, A.P., Machado, G.M., Pianowski, G., Carvalho, L.F.

Engagement, Responsibility, Collaboration, and Abandonment: Nurses' Experiences of Assessing Suicide Risk in Psychiatric Inpatient Care

Suicide risk assessment is a complex task for nurses working in psychiatric inpatient care. This study explored psychiatric inpatient nurses' experiences of assessing suicide risk. A qualitative design was used, and 10 interviews were subjected to qualitative content analysis. Nurses described suicide risk assessments as requiring them to create caring alliances and to take responsibility. Collaborating with colleagues was another part of nurses' experiences, as was feeling abandoned. To make the assessment safely, nurses need a combination of caring alliances, support from colleagues, clear guidelines, training and time for collegial reflection to create a supportive working climate.

Differences in antipsychotic treatment between depressive patients with and without a suicide attempt

BACKGROUND

Depressed suicide attempters are, according to some earlier studies, treated more often with antipsychotics than depressive non-suicide attempters. Cluster B personality disorders, especially borderline personality disorder, are associated with a high suicide risk, and antipsychotics are commonly used for the reduction of symptoms. However, no previous study has taken comorbid personality disorders into account when assessing the use of antipsychotics in patients with unipolar depression. Therefore, the aim of this study was to investigate the clinical selection of pharmacotherapy in unipolar depression with and without a previous suicide attempt, taking into account potential confounders such as cluster B personality disorders.

METHODS

The study sample consisted of 247 patients with unipolar depression. The study was approved by the Regional Ethical Review Board in Lund, Sweden. Study participants were recruited from 4 different secondary psychiatric care clinics in Sweden and were diagnosed according to the DSM-IV-TR with the MINI and SCID II. Previous and ongoing psychiatric treatments were investigated in detail and medical records were assessed.

RESULTS

Thirty percent of the patients had made previous suicide attempts. Depressed suicide attempters underwent both lifetime treatment with antipsychotics and an ongoing antipsychotic treatment significantly more often than non-attempters. Significances remained after a regression analysis, adjusting for cluster B personality disorders, symptom severity, age at the onset of depression, and lifetime psychotic symptoms.

CONCLUSIONS

This is the first study to consider the effect of comorbidity with cluster B personality disorders when comparing treatment of depressive suicide and non-suicide attempters. Our findings suggest that suicide attempters are more frequently treated with antipsychotics compared to non-suicide attempters, regardless of cluster B personality disorder comorbidity. These findings are important for clinicians to consider and would also be relevant to future studies evaluating reduction of suicide risk with antipsychotics in patients with psychiatric comorbidity and a history of attempted suicide.

Using Life Trajectories Analysis to Characterize Suicide Attempts in Prison

Background: Suicide in prison is a major problem and several risk factors have been identified in the literature (e.g., period of incarceration, depressive disorders). Aims: The study examined the impact of several risk factors for suicide attempts before and during incarceration using life trajectory analysis of inmates by interviews with informants. Method: The lifetime of inmates with a history of suicide attempts (ISA; n = 20) or without (IWSA; n = 29) was recounted on a life chart according to four main domains (health, life events, relationships, and judiciary domain) organized in two different periods (predetention and current detention). Life charts were compared between the two groups and a predictive model of suicide risk was constructed using logistic regression and receiving operating characteristic curve analysis. Results: Before detention, more depressive experiences were observed in ISA than in IWSA, and ISA reported more behavioral disorders than IWSA during current detention. Moreover, the total burden for ISA was greater than that for IWSA. The predictive model identified three dimensions for differentiating ISA from IWSA: mood disorders before detention, behavioral disorders, and the quality of relationships with nuclear family during detention. Limitations: Interviews with inmates would have been informative. Conclusion: The accumulation of life events and behavioral manifestations should be incorporated in the developmental trajectory as a therapeutic model regarding suicide in prison.

Dance Movement Therapy for Clients With a Personality Disorder: A Systematic Review and Thematic Synthesis

Background: People with a personality disorder (PD) suffer from enduring inflexible patterns in cognitions and emotions, leading to significant subjective distress, affecting both self and interpersonal functioning. In clinical practice, Dance Movement Therapy (DMT) is provided to clients with a PD, and although research continuously confirms the value of DMT for many populations, to date, there is very limited information available on DMT and PD. For this study, a systematic literature review on DMT and PD was conducted to identify the content of the described DMT interventions and the main treatment themes to focus upon in DMT for PD.

Methods: A systematic search was conducted across the following databases: EMBASE, MEDLINE, PubMed, WEB OF SCIENCE, PsycINFO/OVID, and SCOPUS following the PRISMA guidelines. The Critical Appraisal Skills Programme for qualitative studies was used to rank the quality of the articles. The Oxford Center for Evidence-based Medicine standards were applied to determine the hierarchical level of best evidence. Quantitative content analysis was used to identify the intervention components: intended therapeutic goals, therapeutic activities leading to these goals, and suggested therapeutic effects following from these activities. A thematic synthesis approach was applied to analyze and formulate overarching themes.

Results: Among 421 extracted articles, four expert opinions met the inclusion criteria. Six overarching themes were found for DMT interventions for PD: self-regulation, interpersonal relationships, integration of self, processing experiences, cognition, and expression and symbolization in movement/dance. No systematic descriptions of DMT interventions for PD were identified. A full series of intervention components could be synthesized for the themes of self-regulation, interpersonal relationships, and cognition. The use of body-oriented approaches and cognitive strategies was in favor of dance-informed approaches.

Conclusions: Dance movement therapists working with PD clients focus in their interventions on body-related experiences, non-verbal interpersonal relationships, and to a lesser extent, cognitive functioning. A methodological line for all intervention components was synthesized for the themes of self-regulation, interpersonal relationships, and cognition, of importance for developing systematic intervention descriptions. Future research could focus on practitioners' expertise in applying DMT interventions for PD to develop systematic intervention descriptions and explore the suitability of the identified themes for clinical application. Clients' experiences could offer essential insights on how DMT interventions could address PD pathology and specific PD categories.

Investigating the stress-related fluctuations of level of personality functioning: A critical review and agenda for future research

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the International Classification of Diseases (ICD-11) proposed a dimensional approach to the assessment of personality disorders (PDs). Both models dictate that the clinician first determines PD severity before assessing maladaptive traits, invoking the level of personality functioning (LPF) construct. We consider LPF a promising dimensional construct for translational research because of its clinical importance and conceptual overlap with the Research Domain Criteria (RDoC) Social Processes. We aim to identify biomarkers that co-vary with fluctuations in LPF in adulthood, ultimately to predict persistent decrease in LPF, associated with suicidality and morbidity. However, a theoretical framework to investigate stress-related oscillations in LPF is currently missing. In this article, we aim to fill this hiatus with a critical review about stress and LPF. First, we discuss acute stress and LPF. We briefly present the basics of the neurophysiological stress response and review the literature on momentary and daily fluctuations in LPF, both at a subjective and physiological level. Second, we review the effects of chronic stress on brain function and social behaviour and recapitulate the main findings from prospective cohort studies. This review underlies our suggestions for multimethod assessment of stress-related oscillations in LPF and our theoretical framework for future longitudinal studies, in particular studies using the experience sampling method (ESM).

Premature mortality of people with personality disorder in the Nottingham Study of Neurotic Disorder

It is known that people with personality disorders die prematurely. This may be connected to high levels of co-morbidity with other psychiatric disorders. To test whether mortality was independent, deaths were examined in a 31-year cohort study of anxious and depressed patients (Nottingham Study of Neurotic Disorder) who also had their personality status assessed at baseline. The severity of personality disturbance was assessed using a method previously used to separate personality disorders into ICD-11 categories. Over the follow-up period, 71 of the cohort of 201 patients had died. Age at death was 5.1 (M) and 5.2 (F) years younger in those with personality disorder compared with no personality disorder, but after adjusting for age at randomization and clinical diagnosis at baseline, these differences reduced to 1.5 (M) and 1.6 (F) years. The longevity of the group was 12 to 18 years less than the general population (p < 0.0001), reinforcing previous findings of premature mortality in common mental illness. Analysis of causes of death showed no meaningful differences in personality groups. The hypothesis that premature death in personality disturbance is independent of mental health status was not supported in this study, despite other evidence from this cohort that general clinical outcome is worse in those with personality disorder. © 2019 John Wiley & Sons, Ltd.

Predictive Factors Associated With Methods of Suicide: The Korean National Investigations of Suicide Victims (The KNIGHTS Study)

Background: Because the suicide mortality depends on the lethality of suicide methods, the identification and prediction of suicide methods are important for suicide prevention. Methods: Examination data of suicide decedents were collected based on police reports. Suicide decedents were divided into groups according to the suicide methods (hanging, gas poisoning, pesticide poisoning, jumping, drug poisoning, and drowning) they used. Predictive factors for each suicide method in comparison to other suicide methods were identified. Results: Among 23,647 subjects, hanging was the most common method of suicide. Regarding gas poisoning, the history of previous suicide attempt was a risk factor and being age of 65 or older was a protective factor. Being age of 65 or older showed a highly strong association with suicide by pesticide poisoning. Being age of 18 or younger and the presence of schizophrenia were associated with jumping. A history of psychiatric outpatient treatment was a risk factor for drug poisoning. Regarding suicide by drowning, schizophrenia was a risk factor, while being age of 65 or older was a protective factor. Limitations: Only eight out of a total of 17 regions in South Korea were examined and included in the data of this study. Also, the methods of suicide were defined as one method that directly caused the death, which could undermine other less fatal methods used. Conclusions: There were differences in predictive factors according to the method of suicide. Predicting the method of suicide in people at high risk for suicide stands to be an important strategy for suicide prevention in clinical settings.

Suicide and associated psychosocial correlates among university students in Taiwan: A mixed-methods study

BACKGROUND/PURPOSE

The trend of suicide rates among young adults has been increasing worldwide. The study aimed to identify the suicide risks and associated psychosocial factors in a large university in Taiwan.

METHODS

This is a mixed-methods study using both questionnaire survey and two open-ended questions for the exploration of qualitative data. An online survey was conducted between two periods of the same semester in 2018 to collect different sources of stress and other suicide correlates. The measurement scales included the 9-item Concise Mental Health Checklist, the University Stress Screening Tool in Taiwan and the Chinese Maudsley Personality Inventory. The participants were required to fulfill two open-ended questions about stress experience and depressive symptoms in the previous month in the end of the questionnaire, which was analyzed using thematic analysis.

RESULTS

A total of 857 university students were recruited (67.9% female participants). Over a quarter of participants were under poor mental health status and more than 60% experienced stressful events in the prior year. A higher suicide risk and neurotic trait was noticed compared to the general public. These results were consistent with the qualitative findings.

CONCLUSION

While identifying several risk factors that cumulatively conduced to higher suicide risks, neuroticism served as a key element in the increased suicide risk among the university students. Suicide prevention strategies for university students should highlight stress management for those with neurotic trait and early suicide risk identification.

Predictors of emergency department visits for suicidal ideation and suicide attempt

OBJECTIVES

This study investigated predictors of emergency department (ED) visits for suicidal ideation and suicide attempt in 2014-15 among patients at six Quebec emergency departments (ED), using administrative data.

METHODS

Participants (n = 11,778) used ED for suicidal ideation (30.4%); suicide attempt (7.0%); or other reasons (61.7%). A multinomial logistic regression was performed using variables described by the Andersen Behavioral Model.

RESULTS

The odds of ED visits for suicidal ideation or suicide attempt was high for adjustment disorders, personality disorders, and prior ED consultations for mental health (MH) reasons, but lower for schizophrenia spectrum and other psychotic disorders, illness acuity levels 3-5 (low severity), and 3+ consultations with outpatient psychiatrists. The odds of visiting ED for suicidal ideation increased in depressive disorders, and in the 12-17 year age range, but decreased in association with 1-2 outpatient psychiatrist consultations. The odds of suicide attempt also increased with alcohol use disorders and drug-induced disorders, but decreased with specific MH interventions at local community health services centers.

CONCLUSION

increasing access to ambulatory care, and care continuity in outreach programs for acute MH disorders, including substance-related disorders, may reduce ED visits for suicidal ideation and suicide attempt, while improving overall service delivery.

Group reminiscence for hope and resilience in care-seekers who have attempted suicide

BACKGROUND

The rate of attempting suicide is growing due to the increasing social and economic problems and a variety of stresses taken by individuals in their lives. Helping people, boosting hope, and improving resilience to life hardships might be helpful in this area. This paper is an attempt to determine the effects of group reminiscence on hope and resilience in care-seekers who have attempted suicide.

METHOD

The study was carried out as a quasi-experimental interventional study. The participants were 57 care-seekers with a history of attempting suicide who met the inclusion criteria. The sampling was done through convenience sampling and the participants were grouped into control (n = 29) and experimental (n = 28) groups randomly. The experimental group received integrated reminiscence sessions (eight sessions; 60-90 min). Hope and resilience of the subjects were measured using Schneider's Hope Scale and Connor and Davidson's Resilience Scale. The scales were filled out by the subjects before, immediately after, and 4 weeks after the intervention.

RESULTS

The mean scores of hope in the experimental and control groups were 34.60 and 38.04, respectively, before the intervention. These figures immediately after the intervention were 44.07 and 35.96 in the experimental and control groups, respectively. 4 weeks after the intervention, the mean scores of hope in the experimental and control groups were 44.39 and 35.79, respectively, which is a statistically significant difference (p < 0.05). In terms of resilience, the mean scores in the experimental and control groups before the intervention were 48.17 and 57.51, respectively; and immediately after the intervention, these figures were 67.71 and 52.75, respectively. 4 weeks of the intervention, the mean scores of resilience were 59.17 and 52.24, respectively, which is a statistically significant difference (p < 0.05).

CONCLUSION

Group reminiscence has a positive effect on boosting hope and resilience in care-seekers who have attempted suicide.

The course of (comorbid) trauma-related, dissociative and personality disorders: two year follow up of the Friesland study cohort

Background: There is substantial comorbidity between trauma-related disorders (TRDs), dissociative disorders (DDs) and personality disorders (PDs), especially in patients who report childhood trauma and emotional neglect. However, little is known about the course of these comorbid disorders, despite the fact that this could be of great clinical importance in guiding treatment. Objective: This study describes the two-year course of a cohort of patients with (comorbid) TRDs, DDs and PDs and aims to identify possible predictors of course. Possible gender differences will be described, as well as features of non-respondents. Method: Patients (N = 150) referred to either a trauma treatment program or a PD treatment program were assessed using five structured clinical interviews for diagnosing TRDs, DDs, PDs and trauma histories. Three self-report questionnaires were used to assess general psychopathology, dissociative symptoms and personality pathology in a more dimensional way. Data on demographics and received treatment were obtained using psychiatric records. We described the cohort after a two-year follow-up and used t-tests or chi-square to test possible differences between respondents and non-respondents and between women and men. We used regression analysis to identify possible course predictors. Results: A total of 85 (56.7%) of the original 150 patients participated in the follow-up measurement. Female respondents reported more sexual abuse than female non-respondents. Six patients (4.0%; all women) died because of suicide. Levels of psychopathology significantly declined during the follow-up period, but only among women. Gender was the only significant predictor of change. Conclusions: Comorbidity between TRDs, DDs and PDs was more the rule than the exception, pleading for a more dimensional and integrative view on pathology following childhood trauma and emotional neglect. Courses significantly differed between men and women, advocating more attention to gender in treatment and future research.

Excessive mortality and causes of death among patients with personality disorder with comorbid psychiatric disorders

PURPOSE

Excessive mortality has been seen in patients with personality disorder (PD), but it has not been well-studied when patients also have other psychiatric comorbidities. This study investigated the mortality rates and causes of death in an Asian cohort with PD.

METHOD

We enrolled patients ≥ 18 years of age with PD as defined by DSM-IV criteria (N = 1172), who had been admitted to a psychiatric service center in northern Taiwan between 1985 and 2008. By linking with the national mortality database (1985-2008), cases of mortality (n = 156, 13.3%) were obtained. We calculated the standardized mortality ratios (SMRs) to estimate the mortality gap between patients with PD and the general population. Stratified analyses of mortality rates by Axis I psychiatric comorbidity and sex were performed.

RESULTS

Borderline PD (n = 391, 33.4%) was the dominant disorder among the subjects. The SMRs for all-cause mortality of PD alone, PD comorbid with non-substance use disorder(non-SUD), and PD comorbid with SUD were 4.46 (95% CI 1.94-6.98), 7.42 (5.99-8.85), and 15.96 (11.07-20.85), respectively. Among the causes of death, the SMR for suicide was the highest (46.92, 95% CI 34.29-59.56). The SMR for suicide in PD patients with comorbid SUD was unusually high (74.23, 95% CI 33.88-114.58). Women had a significant increase in suicide with an SMR of 59.00 (95% CI 37.89-80.11). Men had significant increase in SMRs for cardiovascular disease and gastrointestinal disease.

CONCLUSIONS

We found significant synergistic effects of PD and SUD on mortality risk. A personality assessment should be mandatory in all clinical settings to prevent premature death and detect SUD early.

Personality disorder: a disease in disguise

Personality disorders (PDs) can be described as the manifestation of extreme personality traits that interfere with everyday life and contribute to significant suffering, functional limitations, or both. They are common and are frequently encountered in virtually all forms of health care. PDs are associated with an inferior quality of life (QoL), poor health, and premature mortality. The aetiology of PDs is complex and is influenced by genetic and environmental factors. The clinical expression varies between different PD types; the most common and core aspect is related to an inability to build and maintain healthy interpersonal relationships. This aspect has a negative impact on the interaction between health-care professionals and patients with a PD. From being discrete and categorical disease entities in previous classification systems, the current concept of PD, reflected in the newly proposed ICD-11, is a dimensional description based on the severity of the disturbed functioning rather than on the type of clinical presentation. Insight about the characteristics of PDs among medical practitioners is limited, which is partly because persons do not seek health care for their PD, but instead for other medical issues which are obscured by their underlying personality problems. What needs to be emphasized is that PDs affect both the clinical presentation of other medical problems, and the outcome of these, in a negative manner and that the integrated effects of having a PD are a shortened life expectancy. Accordingly, PDs need to be recognized in clinical practice to a greater extent than previously.

Suicide Methods and Specific Types of Accidental Death and Fatal Poisoning Among Discharged Psychiatric Patients: A National Cohort Study

OBJECTIVE

Persons discharged from inpatient psychiatric units are at greatly elevated risk of dying unnaturally. We conducted a comprehensive examination of specific causes of unnatural death post-discharge in a national register-based cohort.

METHOD

A cohort of 1,683,645 Danish residents born 1967-1996 was followed from their 15th birthday until death, emigration, or December 31, 2011, whichever came first. Survival analysis techniques were used to estimate incidence rate ratios (IRRs) comparing risk for persons with and without psychiatric admission history in relation to (a) suicide method, (b) accidental death type, (c) fatal poisoning type, and (d) homicide.

RESULTS

More than half (52.5%, n = 711) of all unnatural deaths post-discharge were fatal poisonings, compared with less than a fifth (17.0%, n = 1,012) among persons in the general population not admitted. Just 6.8% (n = 92) of all unnatural deaths post-discharge were due to transport accidents-the most common unnatural death type in the general population (53.4%, n = 3,184). Suicide risk was 32 times higher among discharged patients (IRR 32.3; 95% CI, 29.2-35.8) and was even higher during the first year post-discharge (IRR 70.4; 95% CI, 59.7-83.0). Among the suicide methods examined, relative risk values were significantly larger for intentional self-poisoning (IRR 40.8; 95% CI, 33.9-49.1) than for "violent" suicide methods (IRR 29.4; 95% CI, 26.1-33.2). The greatest relative risk observed was for fatal poisoning (irrespective of intent) by psychotropic medication (IRR 93.7; 95% CI, 62.5-140.5). The highest post-discharge mortality rate was for accidental self-poisoning among persons diagnosed with a psychoactive substance abuse disorder: 290.1 per 100,000 person-years.

CONCLUSIONS

Closer liaison between inpatient services and community care, more effective early treatment for comorbid substance abuse, enhanced psychosocial assessment following self-harm, and tighter medication surveillance could decrease risk of unnatural death post-discharge.

[Depression in patients with personality disorder in youth]

AIM

To define clinical specifics of depression in patients with personality disorders (PD) in youth and work out differential/diagnostic criteria of these states.

MATERIAL AND METHODS

One hundred and sixty patients (136 men, 24 women, mean age19.5±3.2 years) were studied. Later 42 patients from this group participated in the follow-up study.

RESULTS

The following types of depression were described: 'with overvalued ideas', 'with neurotic disorders', 'with predominant addictions', 'with youth asthenic incapacity' and 'with attenuated psychotic symptoms'. These types clearly correlate with the type of PD.

CONCLUSION

Personality abnormality plays a role in the pathogenesis of these states. This finding contributes to the more accurate diagnosis, prognostic and therapeutic solutions.

A Social-Ecological Framework of Theory, Assessment, and Prevention of Suicide

The juxtaposition of increasing suicide rates with continued calls for suicide prevention efforts begs for new approaches. Grounded in the Centers for Disease Control and Prevention (CDC) framework for tackling health issues, this personal views work integrates relevant suicide risk/protective factor, assessment, and intervention/prevention literatures. Based on these components of suicide risk, we articulate a Social-Ecological Suicide Prevention Model (SESPM) which provides an integration of general and population-specific risk and protective factors. We also use this multi-level perspective to provide a structured approach to understanding current theories and intervention/prevention efforts concerning suicide. Following similar multi-level prevention efforts in interpersonal violence and Human Immunodeficiency Virus (HIV) domains, we offer recommendations for social-ecologically informed suicide prevention theory, training, research, assessment, and intervention programming. Although the SESPM calls for further empirical testing, it provides a suitable backdrop for tailoring of current prevention and intervention programs to population-specific needs. Moreover, the multi-level model shows promise to move suicide risk assessment forward (e.g., development of multi-level suicide risk algorithms or structured professional judgments instruments) to overcome current limitations in the field. Finally, we articulate a set of characteristics of social-ecologically based suicide prevention programs. These include the need to address risk and protective factors with the strongest degree of empirical support at each multi-level layer, incorporate a comprehensive program evaluation strategy, and use a variety of prevention techniques across levels of prevention.

Personality pathology and intentional self-harm: cross-cutting insights from categorical and dimensional models

This paper reviews current literature on the links between personality pathology and intentional self-harm, including nonsuicidal self-injury (NSSI) and suicidal behaviors. Specifically, this review highlights recent advances stemming from longitudinal, epidemiological, and health registry studies, as well as emerging research on pathological personality traits and intentional self-harm, and integrates current knowledge across dimensional and categorical frameworks to provide recommendations for clinical practice and future research. This review provides strong evidence that personality disorders marked by intense and unstable negative affect, detachment/low extraversion, aggression/hostility, and specific facets of impulsivity may be considered risk factors for suicidal behaviors. Further, there is some evidence of a stronger relation between maladaptive personality traits and suicidal versus non-suicidal intentional self-harm.

Forensic toxicology analysis of self-poisoning suicidal deaths in Tehran, Iran; trends between 2011-2015

Background

Suicide ranks among the top ten causes of death in all age groups all over the world. There are many methods for committing suicide including self-poisoning, firearm and hanging. The aim of the present study was to provide an overview of self-poisoning related suicidal deaths with special focus on forensic toxicology analysis results in Tehran, Iran from 2011 to 2015.

Methods

All suspicious cases with the the history of self-poisoning were investigated to define the cause and manner of death under the supervision of forensic medicine practitioners. Postmortem samples were analysed in forensic toxicology laboratory to confirm the presence of drugs in cadaver of suicidal cases. Drugs and poisons were analysed using thin layer chromatography, high performance liquid chromatography, gas chromatography/mass spectrometry, headspace gas chromatography and gas chromatography equipped with nitrogen phosphorus detector. Demographic data were collected from autopsy reports of all cases with confirmed self-poisoning suicidal cause of death.

Results

Results showed that 674 cases of self-poisoning deaths were investigated during a five-year study period, of which 68.55% were male. The most often used suicide method was self-poisoning in young population. Phosphine gas liberated from aluminum phosphide tablets was the most toxic substance detected in postmortem samples (619 cases) followed by opioids, methamphetamine, organophosphates, cyanide and strychnine.

Conclusion

In conclusion self-poisoning suicidal death was predominant in young male population in Tehran, Iran. It seems that free access to suicide means such as drugs and poisons should be restricted by national and health authorities.
