Kovess-Masfety V, Boyd A, Haro J, Bruffaerts R, Villagut G, Lépine J, Gasquet I, Alonso J. High and low suicidality in Europe: a fine-grained comparison of France and Spain within the ESEMeD surveys. J Affect Disord 2011; 133:247-56. [PMID: 21621264 PMCID: PMC4559343 DOI: 10.1016/j.jad.2011.04.014] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2011] [Revised: 04/20/2011] [Accepted: 04/20/2011] [Indexed: 11/24/2022]
Abstract
BACKGROUND Suicidality risk-factors between countries with similar economic and religious background have been rarely compared, especially within genders. METHODS Lifetime prevalence of suicide ideation, plans, and attempts in the ESEMeD surveys were stratified on four separate groups: French women, Spanish women, French men, and Spanish men. Outcome odds-ratios (OR) were modelled within each group using logistic regression including demographic characteristics, lifetime mood/anxiety disorders, parental bonding, marital status, and health service-use. RESULTS Lifetime prevalence of suicide attempts was 3.4% in France (1.1% men, 5.4% women) and 1.5% in Spain (1.2% men, 1.7% women), with a significantly greater gender difference in France (p=0.001). Regarding risk-factors, French women reported suicide attempt more commonly with authoritarian mothers (OR=1.51; 95%CI=1.04-2.18), unlike Spanish women (OR=0.77; 95%CI=0.51-1.15) (p<0.001). Spanish men showed more than eight-times higher odds of suicide attempt with overprotecting mothers than French men (p=0.03). General practitioner-(GP)-use was significantly protective of suicide attempt among Spanish women (OR=0.08; 95%CI=0.02-0.35) with no effect in French women (OR=1.03; 95%CI=0.54-2.00) (p=0.01). No significant differences in the effect of marital status, any lifetime antidepressant use, mental disorders, or religiosity on suicide attempt were observed between France and Spain within gender-stratum. LIMITATIONS Parental bonding is retrospective and potentially influenced by mental state. Response rate was considerably lower in France than in Spain. CONCLUSIONS Suicidality risk-factors play different roles across genders between France and Spain. Parental bonding dimensions may be interpreted differently according to country, underlining cultural importance. As recommended by WHO, mental health decisions must involve GPs in conjunction with psychiatrists or psychologists.

Abstract
OBJECTIVES Adult ADHD is characterised by a plethora of comorbid conditions. However, the comorbidity of schizophrenia and ADHD does not seem to be a typical feature and is therefore under-researched. OBJECTIVE To identify adult patients with schizophrenia and comorbid ADHD and compare their symptomatology with schizophrenic patients without ADHD. METHOD Performance in specific neuropsychological tests (set shifting, selective and sustained attention, cognitive performance, and speed of information processing) was determined. Additionally, important demographic data and information about the patients' history such as the number of suicide attempts were gathered. Twenty-seven patients were involved in this study (14 male and 13 female). Fifteen patients were diagnosed with schizophrenia/no ADHD and twelve had both schizophrenia/ADHD. RESULTS We report here an increase in suicidal behaviour of patients with both schizophrenia and ADHD compared to schizophrenia only. A significant underperformance of the patients with ADHD comorbidity compared to patients with schizophrenia only was also determined. CONCLUSIONS The increased suicidal behaviour in patients with schizophrenia and ADHD suggests the need of further studies on mood regulation and suicidal ideations in these patients.

Abstract
Huntington disease (HD) is a neurodegenerative condition characterized by cognitive impairments, motor abnormalities, and psychiatric disturbance. An increased risk for suicide has been documented. The majority of HD research has focused on cognitive and motor features of HD; the implications of psychiatric manifestations have received less consideration. Recent studies have sought to identify the stages of HD in which patients are at increased risk to experience suicidal ideation, though no study has examined possible risk factors for suicidality. The current study examines the presence of psychiatric comorbidity and its involvement in suicidal ideation. Suicidal ideation was examined in 1941 HD patients enrolled in the Huntington Study Group. Of those, 19% (N=369) endorsed current suicidal ideation. Logistic regression analyses indicated that depression/anxiety and aggression/irritability are significant predictors of suicidal ideation. In a subsample with the greatest suicidal ideation, alcohol and drug abuse were also predictive. It is recommended that all individuals with HD (specifically those with features of depression, aggression, substance abuse) have routine suicide assessment; further research is needed to understand the high rate of suicide in HD.

Abstract
All suicides by Hispanics (n = 434) and non-Hispanic Whites (n = 3,370) in Colorado from 2004 to 2008 using the Violent Death Reporting System were examined. Hispanic victims were significantly younger. Adjusting for age and gender, Hispanic victims were less likely to have reported depressed mood [odds ratio (OR) 0.78; 95% confidence interval (CI) 0.63-0.97], mental health diagnosis (OR 0.53; 95% CI 0.41-0.7), or current psychiatric treatment (OR 0.47; 95% CI 0.43-0.77). There were no differences in reports of financial, relationship, job, or legal stresses. Hispanic suicides were equally likely to be by overdose, firearm, or hanging, but more likely to be in jail (OR 2.68; 95% CI 1.55-4.65). To prevent suicides, stronger partnerships are needed among public health, medical, mental health, and criminal justice professionals.

Abstract
BACKGROUND AND AIM Individuals with coeliac disease have increased risk of depression and death from external causes, but conclusive studies on death from suicide are missing. We examined the risk of suicide in coeliac disease and amongst individuals where the small intestinal biopsy showed no villous atrophy. METHODS We collected biopsy data from all 28 clinical pathology departments in Sweden for individuals diagnosed during 1969-2007 with coeliac disease (Marsh 3: villous atrophy; n=29,083 unique individuals), inflammation without villous atrophy (Marsh 1-2; n=13,263) or positive coeliac disease serology but normal mucosa (Marsh 0, n=3719). Through Cox regression we calculated Hazard ratios for suicide as recorded in the Swedish Cause of Death Register. RESULTS The risk for suicide was higher in patients with coeliac disease compared to general population controls (HR=1.55; 95%CI=1.15-2.10; based on 54 completed suicides). Whilst suicide was also more common amongst individuals with inflammation (HR=1.96; 95%CI=1.39-2.77), no such increase was seen amongst individuals with a normal mucosa but positive coeliac disease serology (HR=1.06; 95%CI=0.37-3.02). CONCLUSIONS We found a moderately increased risk of suicide amongst patients with coeliac disease. This merits increased attention amongst physicians treating these patients.

Abstract
BACKGROUND An association between sense of coherence (SOC) and suicidal behavior has been suggested. The aim of this study was to identify factors associated with low SOC in elderly suicide attempters. METHODS Eighty non-demented hospital-treated suicide attempters aged 70 years and older (38 men, 42 women, mean age 79.4 years) took part in an interview with a research psychologist and completed the 29-item SOC questionnaire. The interview included questions regarding social situation and health-related factors. The Comprehensive Psychopathological Rating Scale (CPRS) provided symptom ratings that were used in a diagnostic algorithm for DSM-IV major depression. The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) was used to identify individuals with serious physical illness. RESULTS There was a strong relationship between major depression and SOC. While we could show no relationship between severe physical illness and SOC, associations were demonstrated with social variables including too little time spent with children, too little time spent with grandchildren and having moved within the past five years. These associations remained significant in regression models adjusted for sex, age and major depression. CONCLUSIONS A number of social variables were independently related to SOC in elderly suicide attempters. Prospective studies are needed in order to determine whether SOC-strengthening interventions can reduce the risk of suicidal behavior in seniors.

Abstract
OBJECTIVES. We aimed at reviewing studies exploring dysfunctional cognitive processes, and their neuroanatomical basis, in suicidal behaviour, and to develop a neurocognitive working model. Methods. A literature search was conducted. RESULTS. Several limitations were found. The main reported neuropsychological findings are a higher attention to specific negative emotional stimuli, impaired decision-making, lower problem-solving abilities, reduced verbal fluency, and possible reduced non-specific attention and reversal learning in suicide attempters. Neuroimaging studies mainly showed the involvement of ventrolateral orbital, dorsomedial and dorsolateral prefrontal cortices, the anterior cingulate gyrus, and, to a lesser extent, the amygdala. In addition, alterations in white matter connections are suggested. CONCLUSIONS. These studies support the concept of alterations in suicidal behaviour distinct from those of comorbid disorders. We propose that a series of neurocognitive dysfunctions, some with trait-like characteristics, may facilitate the development of a suicidal crisis during stressful circumstances: (1) an altered modulation of value attribution, (2) an inadequate regulation of emotional and cognitive responses, and (3) a facilitation of acts in an emotional context. This preliminary model may represent a framework for the design of future studies on the pathophysiology, prediction and prevention of these complex human behaviours.

Abstract
Suicide is a public health problem and a leading cause of death. The number of people thinking seriously about suicide, making plans, and attempting suicide is surprisingly high. In total, primary care clinicians write more prescriptions for antidepressants than mental health clinicians and see patients more often in the month before their death by suicide. Treatment of depression by primary care physicians is improving, but opportunities remain in addressing suicide-related treatment variables. Collaborative care models for treating depression have the potential both to improve depression outcomes and decrease suicide risk. Alcohol use disorders and anxiety symptoms are important comorbid conditions to identify and treat. Management of suicide risk includes understanding the difference between risk factors and warning signs, developing a suicide risk assessment, and practically managing suicidal crises.

Abstract
BACKGROUND Community surveys indicate that many people with depressive disorders do not obtain professional help and that a preference for self-reliance is an important factor in this treatment gap. The current study sought to investigate whether stigmatising attitudes predict a belief in the helpfulness of dealing with depression without external assistance. METHODS Data were collected as part of a national household survey of 2000 Australian adults aged 18 years and above. Participants were presented with either a vignette depicting depression (n=1001) or a vignette depicting depression with suicidal ideation (n=999) and asked if it would be helpful or harmful to deal alone with the problem. Logistic regression analyses were conducted to determine if belief in dealing with depression alone was predicted by personal stigma, perceived stigma or sociodemographic characteristics. RESULTS Higher levels of personal stigma independently predicted a belief in the helpfulness of dealing alone with both depression and depression with suicidal ideation. By contrast, lower levels of perceived stigma were associated with a belief in the helpfulness of dealing alone with depression without suicidal ideation. CONCLUSIONS Personal stigma is associated with a belief in the helpfulness of self-reliance in coping with depression. Public health programs should consider the possibility that a belief in self-reliance is partly attributable to stigma. The findings also point to the potential importance of providing evidence-based self-help programs for those who believe in self-care.

Abstract
Toxoplasma gondii (T. gondii) is an intracellular protozoan parasite that infects roughly a third of the world population. In an immunocompetent host, infection is generally chronic and asymptomatic, as the immune system keeps T. gondii confined to cysts and the intracellular space within the muscle and brain. Seropositivity has been linked to schizophrenia, car accidents, changes in personality, and more recently, suicidal attempts. Very recently, seroprevalence for 20 European countries was found to be associated with increased suicide rates. Although suicide rates were age-standardized, given that T. gondii seroprevalence increases with age and that the blood samples were drawn in women, we now retested in women only the association between suicide and T. gondii seropositivity, stratified by age. Simple correlations between ranked T. gondii seropositivity and suicide rate identified statistically significant relationships in women 60 years or older (p < 0.05); adjusting for GDP, the statistical significance expanded to include women 45 years and older. The strongest association was in the 60- to 74-year-old group where, after adjustment for GDP, the relationship (p = 0.007) resisted Bonferroni adjustment for multiple comparisons. In conclusion, the results suggest that a positive relationship between rates of infection with T. gondii and suicide is apparent in women of postmenopausal age. Prospective studies are necessary to further confirm this association predictively and to explore mechanisms mediating this relationship.

Abstract
BACKGROUND Suicide is a leading cause of death worldwide; however, little information is available about the treatment of suicidal people, or about barriers to treatment. AIMS To examine the receipt of mental health treatment and barriers to care among suicidal people around the world. METHOD Twenty-one nationally representative samples worldwide (n=55 302; age 18 years and over) from the World Health Organization's World Mental Health Surveys were interviewed regarding past-year suicidal behaviour and past-year healthcare use. Suicidal respondents who had not used services in the past year were asked why they had not sought care. RESULTS Two-fifths of the suicidal respondents had received treatment (from 17% in low-income countries to 56% in high-income countries), mostly from a general medical practitioner (22%), psychiatrist (15%) or non-psychiatrist (15%). Those who had actually attempted suicide were more likely to receive care. Low perceived need was the most important reason for not seeking help (58%), followed by attitudinal barriers such as the wish to handle the problem alone (40%) and structural barriers such as financial concerns (15%). Only 7% of respondents endorsed stigma as a reason for not seeking treatment. CONCLUSIONS Most people with suicide ideation, plans and attempts receive no treatment. This is a consistent and pervasive finding, especially in low-income countries. Improving the receipt of treatment worldwide will have to take into account culture-specific factors that may influence the process of help-seeking.

Abstract
OBJECTIVES To assess suicide risk in men with mood disorders at the postpartum period. METHODS We conduct a longitudinal study with 650 men whose child has born from April 2007 to May 2008 at maternity hospital. The first assessment was in the antenatal period and the second within 30 to 60days postpartum. Suicide risk, anxiety disorders, hypomanic, manic and mixed episodes were assessed by the Mini International Neuropsychiatric Interview (MINI). RESULTS The prevalence of suicide risk in fathers in postpartum was of 4.8%. Fathers with postpartum depression were 20.97 (CI: 5.74; 76.53) more likely to present suicide risk and those with mixed episodes showed a chance of 46.50 (CI: 10.52; 205.53) times higher than those who did not suffer from any mood disorder. CONCLUSION Mixed episodes are common in fathers at postpartum, posing a higher suicide risk than depressive and manic/hypomanic episodes. Therefore, in order to reduce the suicide risk, clinicians should address and treat adequately mixed affective states in this specific population.

Abstract
OBJECTIVE To determine whether a specific component of hostility (i.e. cognitive or behavioural) may predict suicide in a prospective design, controlling for depressive mood. METHOD In 1993, 14,752 members of the 'GAZ et ELectricité' (GAZEL) cohort (10,819 men, mean age=49.0 years; 3933 women, mean age=46.2 years) completed the Center for Epidemiologic Studies Depression Scale and at least one subscale (i.e. cognitive or behavioural hostility) of the Buss and Durkee Hostility Inventory. Dates and causes of death were obtained annually. RESULTS During a mean follow-up of 15.7 years, 28 participants completed suicide (24 men, four women). Suicide was predicted by depressive mood [relative index of inequality (RII) (95% CI)=8.16 (1.97-33.85)] and cognitive hostility [RII (95% CI)=10.76 (2.50-46.42)], but not behavioural hostility [RII (95% CI)=1.37 (0.38-4.97)]. These associations remained significant after adjustment for potential confounders. After mutual adjustment, however, suicide remained significantly associated with cognitive hostility [RII (95% CI)=8.87 (1.52-51.71)] (RII reduction: 34.6%), but no longer with depressive mood [RII (95% CI)=2.03 (0.41-10.07)] (RII reduction: 79.1%). CONCLUSION Cognitive rather than behavioural hostility is associated with an increased risk of suicide, independently of baseline depressive mood.

Abstract
BACKGROUND Suicide rates are high in elderly people with depressive disorder. We compared behavioural, clinical and care characteristics of depressed elderly patients, aged 60years and over at the time of death by suicide, with an early-onset depression (EOD, onset before 60years) with those patients with a late age of onset (LOD). METHOD From a 10-year national clinical survey of all suicides in England and Wales (n=13066) we identified 549 LOD cases, and 290 EOD cases. EOD and LOD cases were compared by logistic regression adjusted for age at suicide. RESULTS Method of suicide did not differ by age of onset of depression. LOD cases were significantly less likely to have a history of psychiatric admissions (OR=0.2 [0.1-0.3]), alcohol misuse (OR=0.6 [0.4-0.9]) and self-harm (0.6 [0.4-0.8]). LOD cases also had a lower prevalence of a psychiatric co-morbid diagnosis (0.6 [0.4-0.7]) and a lower prescription rate for psychotropic drugs other than antidepressants. Furthermore, the number of recent life-events was significantly higher (OR=1.4 [1.0-1.9]) in LOD while the frequency of recent self-harm was similar to EOD. CONCLUSION Although our study suggests that psychopathology of suicide among elderly depressed patients differs between EOD and LOD, the final pathway (via recent self-harm) to suicide may be similar in up to a quarter of patients in both groups. Our results suggest that strategies to enhance coping abilities and provision of support to negate the effects of life-events might be especially important in the prevention of suicide in LOD.

Abstract
BACKGROUND Substance-related deaths account for a great number of suicides. AIM To investigate levels and characteristics of suicide verdicts, as opposed to accidental deaths, in substance misusers. METHODS Psychological autopsy study of cases from the UK National Programme on Substance Abuse Deaths (np-SAD) during the period 2001-2007. RESULTS Between January 2001 and December 2007, 2108 suicides were reported to the np-SAD. Typical suicide victims were White and older than 50 (respectively 95% and 41% of cases). Medications, especially antidepressants (44%), were prescribed to 87% of victims. Significantly fewer suicide victims than controls presented positive blood toxicological results for illicit drugs (namely: cocaine, heroin, amphetamines, ecstasy-type drugs, cannabis, and GHB/GBL) and alcohol. CONCLUSIONS Suicide prevention programmes should devote specific attention to deaths among substance misusers who are at high risk of fatal intentional self-harm. Specific characteristics distinguish those at risk; caregivers should be better educated as to what these factors are. Limitations of the current study included lack of provision of comprehensive information relating to the victims' psychosocial variables. Furthermore, no differentiation between different classes of antidepressants in terms of involvement in suicide was here provided.

Abstract
Background. Depressive disorders are associated with substantial risk of premature mortality. A number of factors may contribute to reported risk estimates, making it difficult to determine actual risk of excess mortality in community cases of depression. The aim of this study is to conduct a systematic review and meta-analysis of excess mortality in population-based studies of clinically defined depression. Methods. Population-based studies reporting all-cause mortality associated with a clinically defined depressive disorder were included in the systematic review. Estimates of relative risk for excess mortality in population-representative cases of clinical depressive disorders were extracted. A meta-analysis was conducted using Stata to pool estimates of excess mortality and identify sources of heterogeneity within the data. Results. Twenty-one studies reporting risk of excess mortality in clinical depression were identified. A significantly higher risk of mortality was found for major depression (RR 1.92 95% CI 1.65–2.23), but no significant difference was found for dysthymia (RR 1.37 95% CI 0.93–2.00). Relative risk of excess mortality was not significantly different following the adjustment of reported risk estimates. Conclusion. A mortality gradient was identified with increasing severity of clinical depression. Recognition of depressive symptoms in general practice and appropriate referral for evidence-based treatment may help improve outcomes, particularly in patients with comorbid physical disorders.

Suicide death and hospital-treated suicidal behaviour in asylum seekers in the Netherlands: a national registry-based study. BMC Public Health 2011; 11:484.

Abstract
BACKGROUND Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. METHODS We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+). The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. RESULTS The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83). No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07). The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. CONCLUSIONS In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour was higher in several subgroups of asylum seekers than that in the reference population. We conclude that measures to prevent suicide and suicidal behaviour among asylum seekers in the Netherlands are indicated.

Abstract
BACKGROUND Women with fertility problems often experience higher levels of stress, anxiety and depressive symptoms associated with both the infertility diagnosis and eventual fertility treatment. The authors investigated whether women who do not succeed in having a child after an infertility evaluation are at a higher risk of suicide than women who succeed in having a child after an infertility evaluation. METHODS A cohort of 51 221 Danish women with primary or secondary infertility and referred to hospitals or private fertility clinics in Denmark during 1973-1998 was established. The cohort was linked to four Danish administrative population-based registries. Each woman was followed from the date of her initial fertility evaluation at the clinic or hospital until 2006. Cox proportional hazards regression analyses was used to calculate hazard ratios (HRs) for suicide and their corresponding 95% confidence intervals (CIs) adjusted for potential confounders. RESULTS Women who did not have a child after an initial fertility evaluation had a >2-fold (HR: 2.43; 95% CI: 1.38-3.71) greater risk of suicide than women who had at least one child after a fertility evaluation. Women with secondary infertility, i.e. women who had a child before a fertility evaluation but did not succeed in having one after, also had an increased risk for suicide (HR: 1.68; 95% CI, 0.82-3.41) compared with women who succeeded in having another child, although the risk estimate failed to reach significance. CONCLUSIONS Health-care personnel treating women with fertility problems should be aware of the emotional response of their patients in order to recognize and treat possible psychiatric morbidity after fertility problems.

Abstract
PURPOSE OF REVIEW The risk of suicide is thought be increased in epilepsy. Antiepileptic drugs (AEDs) remain the primary treatment. An FDA alert in 2008 raised concerns that AEDs may increase the risk of suicidal thoughts and behaviour. The risk profile for suicide in epilepsy is examined in the context of recent reports investigating the risk of suicide and the reported association between AEDs and risk of suicide. RECENT FINDINGS Following a diagnosis of epilepsy the risk of completed suicide is increased (standardized mortality ratio 2-3.5); although the causes remain poorly understood, co-morbid depression and the first 6 months after epilepsy surgery seem to be particular risk factors. The evidence for AEDs increasing risk for suicide remains mixed and is based on retrospective data. SUMMARY The identification of risk factors such as mood or anxiety disorders in patients with epilepsy should not delay AED treatment as the risks associated with seizures far outweigh the current research evidence for increased AED-related suicide risk. A pragmatic approach to clinical assessment and management is suggested. Prospective AED trials should include validated scales to systematically identify neuropsychiatric complications of AEDs.

Abstract
Animal models are formidable tools to investigate the etiology, the course and the potential treatment of an illness. No convincing animal model of suicide has been produced to date, and despite the intensive study of thousands of animal species naturalists have not identified suicide in nonhuman species in field situations. When modeling suicidal behavior in the animal, the greatest challenge is reproducing the role of will and intention in suicide mechanics. To overcome this limitation, current investigations on animals focus on every single step leading to suicide in humans. The most promising endophenotypes worth investigating in animals are the cortisol social-stress response and the aggression/impulsivity trait, involving the serotonergic system. Astroglia, neurotrophic factors and neurotrophins are implied in suicide, too. The prevention of suicide rests on the identification and treatment of every element increasing the risk.

Abstract
A rapidly growing number of elderly persons and their families are burdened by one or more terminal illnesses in the later years of their life. How best to support their quality of life is a major challenge for healthcare teams. Palliative and end-of-life (PEOL) care is well positioned to respond to this challenge. While the evidence of PEOL is just beginning, much of the suffering can be relieved by what is already known. PEOL care for the elderly needs to go beyond the focus on the patient and should rest on a broad understanding of the nature of suffering that includes family and professional caregivers in that experience of suffering. The dissemination of PEOL care principles should be a public health priority. This article aims to improve understanding of appropriate PEOL care in the elderly and discuss future perspectives.

Abstract
From an evolutionary perspective, suicide is a puzzle, because it has serious adverse effects, yet is remarkably common and heritable. An hypothesis is proposed to explain this puzzle, by explaining how suicide could be adaptive through reducing risk that individuals will transmit infections to kin. Empirical evidence supports four predictions from the hypothesis. There are well-established mechanisms by which infections and immune factors increase risk for mental disorders that contribute to suicide. Suicide is more prevalent in occupations with greater exposure to infection and immune-compromising factors and at higher latitudes, where key environmental factors increase vulnerability to infection. In several other highly social species, suicide-like behaviors have evolved to reduce transmission of infections. If the hypothesis is correct, detection and treatment of underlying infections and immune dysfunction should help predict and prevent suicidal behavior, while also combating spread of infectious diseases.

Abstract
Suicide behavior (SB) spans a spectrum ranging from suicidal ideation to suicide attempts and completed suicide. Strong evidence suggests a genetic susceptibility to SB, including familial heritability and common occurrence in twins. This review addresses recent molecular genetic studies in SB that include case-control association, genome gene-expression microarray, and genome-wide association (GWA). This work also reviews epigenetics in SB and pharmacogenetic studies of antidepressant-induced suicide. SB fulfills criteria for a complex genetic phenotype in which environmental factors interact with multiple genes to influence susceptibility. So far, case-control association approaches are still the mainstream in SB genetic studies, although whole genome gene-expression microarray and GWA studies have begun to emerge in recent years. Genetic association studies have suggested several genes (e.g., serotonin transporter, tryptophan hydroxylase 2, and brain-derived neurotrophic factor) related to SB, but not all reports support these findings. The case-control approach while useful is limited by present knowledge of disease pathophysiology. Genome-wide studies of gene expression and genetic variation are not constrained by our limited knowledge. However, the explanatory power and path to clinical translation of risk estimates for common variants reported in genome-wide association studies remain unclear because of the presence of rare and structural genetic variation. As whole genome sequencing becomes increasingly widespread, available genomic information will no longer be the limiting factor in applying genetics to clinical medicine. These approaches provide exciting new avenues to identify new candidate genes for SB genetic studies. The other limitation of genetic association is the lack of a consistent definition of the SB phenotype among studies, an inconsistency that hampers the comparability of the studies and data pooling. In summary, SB involves multiple genes interacting with non-genetic factors. A better understanding of the SB genes by combining whole genome approaches with case-control association studies, may potentially lead to developing effective screening, prevention, and management of SB.

Abstract
OBJECTIVE To assess symptoms of depression and anxiety in patients with head and neck cancers (HNCs) before and after radiotherapy. DESIGN, PARTICIPANTS AND SETTING Prospective observational study of 102 outpatients with HNCs at a tertiary cancer centre in Melbourne between 1 May 2008 and 30 May 2009. Eligibility criteria were a first-time diagnosis of HNC, age over 17 years, and agreement to undergo cancer treatment involving radiotherapy with curative intent. Data were collected before commencement of radiotherapy and again 3 weeks after completing treatment. MAIN OUTCOME MEASURES Symptoms of depression and anxiety as assessed by the Hospital Anxiety and Depression Scale (HADS); physical and psychosocial aspects of quality of life as assessed by the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N). RESULTS Seventy-five participants completed pretreatment and posttreatment questionnaires. Mean depression scores increased significantly from before to after treatment, while anxiety scores decreased significantly over the same period. The prevalence of mild to severe depression was 15% before treatment and 31% after treatment. The prevalence of mild to severe symptoms of anxiety was 30% before treatment, reducing to 17% after treatment. Posttreatment depression was predicted by pretreatment depression and receiving chemotherapy. Posttreatment anxiety was predicted by pretreatment anxiety and male sex. CONCLUSIONS These findings suggest that rates of depression in patients with HNCs increase after cancer treatment, with a third of patients experiencing clinically significant symptoms of depression after radiotherapy.

Abstract
Although suicide represents 1.8% of the global burden of disease, there are few objective assays for suicide risk. Being associated with depressive disorders, which have a high risk of suicide, the proteins P11, P2RX7, and S100β may be biomarkers for a suicidal disposition. We measured levels of p11 and P2RX7 mRNA in peripheral blood mononuclear cells (PBMCs) of 26 psychiatric patients (11 suicide attempters, 15 suicide non-attempters) with post-traumatic stress disorder (PTSD) and major depressive disorder (MDD), and 14 normal controls, using quantitative real-time PCR. We also conducted a meta-analysis of microarray data of p11, P2RX7 and S100β from post-mortem prefrontal cortex (PFC) of patients who committed suicide (n = 56) and non-suicide controls (n = 61). We found that PBMC p11 mRNA levels were significantly lower in suicide attempters and higher in suicide non-attempters, when compared to normal controls. The PFC p11 mRNA levels in suicide completers were also lower than non-suicide controls (adjusted p = 0.007). Unlike p11, PBMC P2RX7 mRNA levels were significantly lower than normal controls in all patients including suicide attempters, suicide non-attempters, and suicide completers. In addition, levels of S100β in PFC did not differ between suicide completers and non-suicide controls. These results suggest that PBMC p11 mRNA levels may be a potential adjunctive biomarker for the assessment of suicide risk in mental disorders and warrants a larger translational study to determine its clinical utility.

Abstract
The suicide rate of Hungary is the highest in the world averaged over the last century but it has shown a very pronounced decrease since 1987. To explore the background of this decrease we investigated the associations between some known suicide-related factors (i.e. tobacco use, antidepressant use and alcohol consumption at the population level) and the suicide rate between 1985 and 2008. The total number of man-hours worked per year by psychiatrists in the outpatient service system and real GDP growth were also monitored in our study. A time series analysis model was constructed to investigate the associations between the above variables and the suicide rate. In the unadjusted model annual tobacco consumption was significantly associated with the suicide rate in a positive manner, while antidepressant use and man-hours were significantly associated with the suicide rate in a negative manner. After adjustment, the associations remained significant only for tobacco consumption and antidepressant use. Neither alcohol consumption nor real GDP growth was associated with the suicide rate in any models. Our results from group-level data confirmed the role of smoking in suicidal behavior previously suggested mainly by studies using individual-level data and also corroborated the results of previous ecological studies concerning the inverse association between antidepressant use and suicide rate. These findings and the results of previous studies - investigating the relationship between smoking and the risk of suicidal behavior at the individual-level - may suggest that programs to prevent tobacco use or to address the widespread recognition and treatment of depression may also prevent suicidality.

Abstract
BACKGROUND Suicide and suicide attempts represent a severe problem for public health services. The aim of this study is to determine the socio-demographic and psychopathological variables associated with suicide attempts in the population admitted to a General Hospital. METHODS An observational-descriptive study of patients admitted to the A Coruña University Hospital (Spain) during the period 1997-2007, assessed by the Consultation and Liaison Psychiatric Unit. We include n = 5,234 admissions from 4,509 patients. Among these admissions, n = 361 (6.9%) were subsequent to a suicide attempt. Admissions arising from a suicide attempt were compared with admissions occurring due to other reasons.Multivariate generalised estimating equation logistic regression models were used to examine factors associated with suicide attempts. RESULTS Adjusting by age, gender, educational level, cohabitation status, being employed or unemployed, the psychiatric diagnosis at the time of the interview and the information on previous suicide attempts, we found that the variables associated with the risk of a suicide attempt were: age, psychiatric diagnosis and previous suicide attempts. The risk of suicide attempts decreases with age (OR = 0.969). Psychiatric diagnosis was associated with a higher risk of suicide attempts, with the highest risk being found for Mood or Affective Disorders (OR = 7.49), followed by Personality Disorders (OR = 7.31), and Schizophrenia and Other Psychotic Disorders (OR = 5.03).The strongest single predictive factor for suicide attempts was a prior history of attempts (OR = 23.63). CONCLUSIONS Age, psychopathological diagnosis and previous suicide attempts are determinants of suicide attempts.

Abstract
Background Mental disorders are strongly associated with excess suicide risk, and successful treatment might prevent suicide. Since 1990, and particularly after 1998, there has been a substantial increase in mental health service resources in Norway. This study aimed to investigate whether these changes have had an impact on suicide mortality. Methods We used Poisson regression analyses to assess the effect of changes in five mental health services variables on suicide mortality in five Norwegian health regions during the period 1990-2006. These variables included: number of man-labour years by all personnel, number of discharges, number of outpatient consultations, number of inpatient days, and number of hospital beds. Adjustments were made for sales of alcohol, sales of antidepressants, education, and unemployment. Results In the period 1990-2006, we observed a total of 9480 suicides and the total suicide rate declined by 26%. None of the mental health services variables were significantly associated with female or male suicide mortality in the adjusted analyses (p > 0.05). Sales of antidepressants (adjusted Incidence Rate Ratio = 0.98; 95% CI = 0.97-1.00) and sales of alcohol (adjusted IRR = 1.41; 95% CI = 1.18-1.72) were significantly associated with female suicide mortality; education (adjusted IRR = 0.86; 95% CI = 0.79-0.94) and unemployment (adjusted IRR = 0.91; 95% CI = 0.85-0.97) were significantly associated with male suicide mortality. Conclusions The adjusted analyses in the present study indicate that increased resources in Norwegian mental health services in the period 1990-2006 were statistically unrelated to suicide mortality.

Abstract
Self-inflicted burns are rare in France, but they lead to major, often life-threatening complications. The authors reviewed medical data for patients hospitalized in a burn center from January 2004 to December 2008. Thirty-eight cases of self-inflicted burns were compared with 220 accidental burns. Women were predominantly affected (57.9%, n = 22). A psychiatric history (71%, n = 27) was more frequent in this population. The mean age of the victims was 38 years. The leading method of suicide was flame (94%, n = 36) associated with gasoline used as an accelerant (77.7%, n = 28). Mean total burn surface area (41.5%) and mortality (36.9%) were higher in the self-inflicted burn population. By recognizing epidemiological characteristics and patients at risk, we can better classify lesions related to self-immolation. It is important for the forensic physician to consult survival details to correlate these data with the results of autopsy.

Abstract
Background: Suicide prevention can be improved by knowing which variables physicians take into account when considering hospitalization or discharge of patients who have attempted suicide. Aims: To test whether suicide risk is an adequate explanatory variable for predicting admission to a psychiatric unit after a suicide attempt. Methods: Analyses of 840 clinical records of patients who had attempted suicide (66.3% women) at four public general hospitals in Madrid (Spain). Results: 180 (21.4%) patients were admitted to psychiatric units. Logistic regression analyses showed that explanatory variables predicting admission were: male gender; previous psychiatric hospitalization; psychiatric disorder; not having a substance-related disorder; use of a lethal method; delay until discovery of more than one hour; previous attempts; suicidal ideation; high suicidal planning; and lack of verbalization of adequate criticism of the attempt. Conclusions: Suicide risk appears to be an adequate explanatory variable for predicting the decision to admit a patient to a psychiatric ward after a suicide attempt, although the introduction of other variables improves the model. These results provide additional information regarding factors involved in everyday medical practice in emergency settings.

Prison suicide in 12 countries: an ecological study of 861 suicides during 2003-2007. Soc Psychiatry Psychiatr Epidemiol 2011; 46:191-5.

Abstract
BACKGROUND Although suicide rates among prisoners are high and vary between countries, it is uncertain whether this reflects the importation of risk from the general population or is associated with incarceration rates. METHODS We collected data on suicides and undetermined deaths in 12 countries (Australia, Belgium, Canada, Denmark, England and Wales, Finland, Ireland, Netherlands, New Zealand, Norway, Scotland, and Sweden) directly from their prison administrations for 2003-2007. These were compared with rates of suicides in the general population separately by gender using Pearson's correlations. In addition, they were compared with rates of incarceration. Linear regression was used to examine any association after adjustment for rates of incarceration. RESULTS Data were collected on 861 suicides in prison, of which 810 were in men. In the men, crude relative rates of suicide were at least three times higher than the general population. Western European countries had similar rates of prisoner suicide which were mostly higher than those in Australia, Canada, and New Zealand. There was no association between rates of suicide in prisoners and general population rates or rates of incarceration. In the women, inmate suicide rates varied widely and were mostly raised compared with rates in the general population. In addition, these rates did not appear to be associated with general population rates of suicide. CONCLUSIONS Rates of prison suicide do not reflect general population suicide rates, suggesting that variations in prison suicide rates reflect differences in criminal justice systems including, possibly, the provision of psychiatric care in prison.

Abstract
Obstetric and neonatal complications have been associated with completed and attempted suicide (suicidal acts) in young offspring. Maternal smoking is one of the most important risk factors for obstetric complications, but the association between prenatal smoking exposure and offspring risk of suicidal acts is unknown. We performed a population-based study of 1,449,333 single births born in Sweden between 1983 and 1996, derived from linked registry data. Maternal smoking and risks of suicidal acts in offspring were estimated using hazard ratios, derived from proportional-hazard models, controlling for potential confounding of parental socio-demographic factors and psychiatric care in first degree relatives. To control for unmeasured familial confounding, a matched case-control analysis of suicidal acts was performed within sibling pairs discordant for prenatal smoking exposure. In the cohort analysis, the adjusted hazard ratio for completed suicide among offspring to women smoking 1-9 cigarettes and at least 10 cigarettes per day were 1.67, 95% confidence interval (CI), 1.29-2.16, and 1.54, 95% CI, 1.12-2.10. For suicidal acts, corresponding hazard ratios were 1.28, 95% CI 1.21-1.35 and 1.48, 95% CI 1.39-1.57, respectively. However, in sibling pairs discordant for suicidal acts and prenatal smoking exposure, we found no evidence that prenatal smoking exposure increased the risk of suicidal acts. We conclude that the association between prenatal smoking exposure and offspring risk of suicidal acts is probably confounded by unmeasured familial factors.

Abstract
We examined the psychosocial influences on female prisoner suicide by carrying out a study of near-lethal self-harm. We interviewed 60 women prisoners who had recently engaged in near-lethal self-harm (cases) and 60 others who had never carried out near-lethal acts in prison (controls) from all closed female prison establishments in England and Wales, using mixed quantitative and qualitative methods. We gathered information on socio-demographic and criminological variables, life events and childhood trauma, exposure to suicidal behaviour, contributory and precipitating factors for near-lethal self-harm, social support and psychological characteristics. While socio-demographic factors were only modestly associated with near-lethal self-harm, being on remand, in single cell accommodation, and reporting negative experiences of imprisonment were strong correlates. Recent life events and past trauma, including different forms of childhood abuse, were also significantly associated with near-lethal self-harm, as were a family history of suicide and high scores on measures of depression, aggression, impulsivity and hostility, and low levels of self-esteem and social support. Our findings underline the importance of both individual and prison-related factors for suicide in custody, and hence the need for a comprehensive approach to suicide prevention in women's prisons. Given the multiple needs of female prisoners at-risk of self-harm and suicide, complex psychosocial interventions are likely to be required, including interventions for abused and bereaved women, and initiatives to improve staff-prisoner relationships and reduce bullying. The findings of this research may provide insights into factors leading to suicidal behaviour in other forensic and institutional settings, such as detention centres and psychiatric hospitals, and may assist in developing suicide prevention policies for prisoners and other at-risk populations.

Abstract
BACKGROUND Individuals who have attempted suicide are at increased risk of subsequent suicidal behavior. Since 1983, a community-based suicide prevention team has been operating in the municipality of Bærum, Norway. This study aimed to test the effectiveness of the team's interventions in preventing repeated suicide attempts and suicide deaths, as part of a chain of care model for all general hospital treated suicide attempters. METHODS Data has been collected consecutively since 1984 and a follow-up was conducted on all individuals admitted to the general hospital after a suicide attempt. The risk of repeated suicide attempt and suicide were comparatively examined in subjects who received assistance from the suicide prevention team in addition to treatment as usual versus those who received treatment as usual only. Logistic regression and Cox regression were used to analyze the data. RESULTS Between January 1984 and December 2007, 1,616 subjects were registered as having attempted suicide; 197 of them (12%) made another attempt within 12 months. Compared to subjects who did not receive assistance from the suicide prevention team, individuals involved in the prevention program did not have a significantly different risk of repeated attempt within 6 months (adjusted OR = 1.08; 95% CI = 0.66-1.74), 12 months (adjusted OR = 0.86; 95% CI = 0.57-1.30), or 5 years (adjusted RR = 0.90; 95% CI = 0.67-1.22) after their first recorded attempt. There was also no difference in risk of suicide (adjusted RR = 0.85; 95% CI = 0.46-1.57). Previous suicide attempts, marital status, and employment status were significantly associated with a repeated suicide attempt within 6 and 12 months (p < 0.05). Alcohol misuse, employment status, and previous suicide attempts were significantly associated with a repeated attempt within 5 years (p < 0.05) while marital status became non-significant (p > 0.05). With each year of age, the risk of suicide increased by 3% (p < 0.05). CONCLUSIONS The present study did not find any differences in the risk of fatal and non-fatal suicidal behavior between subjects who received treatment as usual combined with community assistance versus subjects who received only treatment as usual. However, assistance from the community team was mainly offered to attempters who were not receiving sufficient support from treatment as usual and was accepted by 50-60% of those deemed eligible. Thus, obtaining similar outcomes for individuals, all of whom were clinically judged to have different needs, could in itself be considered a desirable result.

Abstract
Recent years have seen a growing interest into resilience to suicidality, which has been described as a perception or set of beliefs which buffer individuals from suicidality in the face of stressors. The current review extends this research by introducing the buffering hypothesis, a framework for the investigation of resilience to suicidality. The key proposal of this is that psychological resilience factors should be viewed as existing on a separate dimension to risk which acts to moderate the impact of risk on suicidality. Furthermore, like risk factors, resilience factors are bipolar, with their positive pole conferring resilience and their negative pole acting to amplify suicidality. Seventy-seven studies were identified which investigated (a) whether psychological moderators of risk exist and (b) the particular psychological constructs which may act as moderators. The review found strong support for the existence of psychological moderators and indicated a moderating impact of attributional style, perfectionism, agency and hopelessness. These findings support the buffering hypothesis and suggest that a range of psychological factors may confer resilience to suicidality. These results suggest that the identification of moderators may improve estimates of suicide risk and that the development of buffering factors could be a key focus of suicide interventions.

Abstract
Impulsivity, describing action without foresight, is an important feature of several psychiatric diseases, suicidality and violent behavior. The complex origins of impulsivity hinder identification of the genes influencing both it and diseases with which it is associated. We performed exon-centric sequencing of impulsive individuals in a founder population, targeting fourteen genes belonging to the serotonin and dopamine domain. A stop codon in HTR2B that is common (MAF >1%) but exclusive to Finns was identified. Expression of the gene in the human brain was assessed, as well as the molecular functionality of the stop codon that was associated with psychiatric diseases marked by impulsivity in both population and family-based analyses. Knockout of Htr2b increased impulsive behaviors in mice, indicative of predictive validity. Our study shows the potential for identifying and tracing effects of rare alleles in complex behavioral phenotypes using founder populations, and suggests a role for HTR2B in impulsivity.

Abstract
BACKGROUND Depression is a major cause of suicide worldwide. This association has been reflected by numerous scientific publications reporting about studies to this theme. There is currently no overall evaluation of the global research activities in this field. AIM The aim of the current study was to analyze long-term developments and recent research trends in this area. MATERIAL AND METHODS We searched the Web of Science databases developed by the Thompson Institute of Scientific Information for items concerning depression and suicide published between 1900 and 2007 and analyzed the results using scientometric methods and density-equalizing calculations. RESULTS We found that publications on this topic increased dramatically in the time period 1990 to 2007. The comparison of the different Journals showed that the Archives of General Psychiatry had the highest average citation rate (more than twice that of any other Journal). When comparing authors, we found that not all the authors who had high h-indexes cooperated much with other authors. The analysis of countries who published papers on this topic showed that they published papers in relation to their Gross Domestic Product and Purchasing Power Parity. Among the G8 countries, Russia had the highest male suicide rate in 1999 (more than twice that of any of the other G8 countries), despite having published least papers and cooperating least with other countries among the G8. CONCLUSION We conclude that, although there has been an increase in publications on this topic from 1990 to 2006, this increase is of a lower gradient than that of psoriasis and rheumatoid arthritis.

Abstract
This study aims to provide evidence for the problem of suicide by self-burning in Iraqi Kurdistan. Data were collected prospectively from all patients admitted to the burn center in the province of Sulaymaniyah and cases of self-burning were compared with cases of accidental burns. There were 197 cases with an annual incidence rate of 8.4 per 100,000 per year and female to male risk ratio of 13.1. Independent risk factors for self-burning were female sex (odds ratio 13.75, 95% CI 6.91-27.36, P < 0.001); young age of 11 to 18 years (OR 3.92, 95% CI 2.20-7.0, P < 0.001); poor education (OR 2.50, 95% CI 1.15-5.45, P = 0.02); spring season (OR 2.39, 95% CI 1.3-4.41, P = 0.005); and small family size (OR 2.72, 95% CI 1.44-5.15, P = 0.002). Suicide by self-burning is common in Iraqi Kurdistan especially among women. Urgent action is required to provide a better understanding of the situation, and identify partners, capacities, and opportunities for action.

Abstract
OBJECTIVE The authors recently observed a correlation between state altitude and suicide rate in the United States, which could be explained by higher rates of gun ownership and lower population density in the intermountain West. The present study evaluated the relationship between mean county and state altitude in the United States and total age-adjusted suicide rates, firearm-related suicide rates, and non-firearm-related suicide rates. The authors hypothesized that altitude would be significantly associated with suicide rate. METHOD Elevation data were calculated with an approximate spatial resolution of 0.5 km, using zonal statistics on data sets compiled from the National Geospatial-Intelligence Agency and the National Aeronautics and Space Administration. Suicide and population density data were obtained through the Centers for Disease Control and Prevention (CDC) WONDER database. Gun ownership data were obtained through the CDC's Behavioral Risk Factor Surveillance System. RESULTS A significant positive correlation was observed between age-adjusted suicide rate and county elevation (r=0.51). Firearm (r=0.41) and non-firearm suicide rates (r=0.32) were also positively correlated with mean county elevation. CONCLUSIONS When altitude, gun ownership, and population density are considered as predictor variables for suicide rates on a state basis, altitude appears to be a significant independent risk factor. This association may be related to the effects of metabolic stress associated with mild hypoxia in individuals with mood disorders.

Abstract
INTRODUCTION Suicide risk is most commonly associated with mental illness. In particular, suicide in people under mental health care presents distinct patterns of risk and opportunities for prevention due to their close proximity to specialist care. SOURCES OF DATA The National Confidential Inquiry into Suicide and Homicide by People with Mental Illness (Inquiry) is a unique UK-wide national database of all suicide cases in contact with mental health services in the 12 months preceding suicide. This review presents Inquiry findings from the beginning of the Inquiry in 1996 up to the present (2011) (15 years). AREAS OF AGREEMENT Suicide varies substantially by socio-demographic (age, gender) and clinical features (e.g. diagnosis; care variables). Effective suicide prevention initiatives should incorporate research findings to inform clinical practice and policy. AREAS OF CONTROVERSY Risk assessment remains one of the most difficult areas of clinical practice and management although all areas of clinical practice, research and policy development would benefit from continued high-quality studies. GROWING POINTS The Inquiry work has positively influenced mental health practice and policy in the UK. These changes include: falling suicide rates in mental health patients, informing suicide prevention strategies and developing safety checklists for mental health services. AREAS TIMELY FOR DEVELOPING RESEARCH Investigating suicide in non-mental health settings, investigating suicide following different treatment services and investigating models of service delivery could usefully inform future directions for improving patient safety.

Abstract
The aim of this study was a retrospective analysis of available data on patients who committed suicide after the first episode of schizophrenia with focus on risk factors for suicide. Seven of 162 patients consecutively hospitalized at the Department of Psychiatry in Brno with first-episode schizophrenia and followed up for 10 years committed suicide by hanging (n = 4), shooting (n = 1), jumping from height (n = 1), and drowning (n = 1). All patients had more known risk factors and had visited a psychiatrist shortly before their suicide. However, according to the documentation, the patients were not asked about their intention to commit suicide and the potentially modifiable risk factors. Under the conditions of routine clinical practice, the prevention of suicide after the first psychotic episode should include early aggressive treatment and careful monitoring for suicidal behaviors in patients with known risk factors.
