Abstract
Major depression is a devastating disease affecting an increasing number of people from a young age worldwide, a situation that is expected to be worsened by the COVID-19 pandemic. New approaches for the treatment of this disease are urgently needed since available treatments are not effective for all patients, take a long time to produce an effect, and are not well-tolerated in many cases; moreover, they are not safe for all patients. There is solid evidence showing that the antioxidant capacity is lower and the oxidative damage is higher in the brains of depressed patients as compared with healthy controls. Mitochondrial disfunction is associated with depression and other neuropsychiatric disorders, and this dysfunction can be an important source of oxidative damage. Additionally, neuroinflammation that is commonly present in the brain of depressive patients highly contributes to the generation of reactive oxygen species (ROS). There is evidence showing that pro-inflammatory diets can increase depression risk; on the contrary, an anti-inflammatory diet such as the Mediterranean diet can decrease it. Therefore, it is interesting to evaluate the possible role of plant-derived antioxidants in depression treatment and prevention as well as other biomolecules with high antioxidant and anti-inflammatory potential such as the molecules paracrinely secreted by mesenchymal stem cells. In this review, we evaluated the preclinical and clinical evidence showing the potential effects of different antioxidant and anti-inflammatory biomolecules as antidepressants, with a focus on difficult-to-treat depression and conventional treatment-resistant depression.

Abstract
BACKGROUND Rates and risk factors for suicidal behaviour require updating and comparisons among mood disorders.AimsTo identify factors associated with suicidal risk in major mood disorders. METHOD We considered risk factors before, during and after intake assessments of 3284 adults with/without suicidal acts, overall and with bipolar disorder (BD) versus major depressive disorder (MDD), using bivariate comparisons, multivariable regression modelling and receiver operating characteristic (ROC) analysis. RESULTS Suicidal prevalence was greater in BD versus MDD: ideation, 29.2 versus 17.3%; attempts, 18.8 versus 4.78%; suicide, 1.73 versus 0.48%; attempts/suicide ratio indicated similar lethality, 10.9 versus 9.96. Suicidal acts were associated with familial BD or suicide, being divorced/unmarried, fewer children, early abuse/trauma, unemployment, younger onset, longer illness, more dysthymic or cyclothymic temperament, attention-deficit hyperactivity disorder (ADHD), substance misuse, mixed features, hospital admission, percentage time unwell, less antidepressants and more antipsychotics and mood stabilisers. Logistic regression found five independent factors: hospital admission, more depression at intake, BD diagnosis, onset age ≤25 years and mixed features. These factors were more associated with suicidal acts in BD than MDD: percentage time depressed/ill, alcohol misuse, >4 pre-intake depressions, more dysthymic/cyclothymic temperament and prior abuse/trauma. ADHD and total years ill were similar in BD and MDD; other factors were more associated with MDD. By ROC analysis, area under the curve was 71.3%, with optimal sensitivity (76%) and specificity (55%) with any two factors. CONCLUSIONS Suicidal risks were high in mood disorders: ideation was highest with BD type II, attempts and suicides (especially violent) with BD type I. Several risk factors for suicidal acts differed between BD versus MDD patients.Declaration of interestNo author or immediate family member has financial relationships with commercial entities that might appear to represent potential conflicts of interest with the information presented.

Abstract
BACKGROUND Divalproex has become the most prevalent mood stabilizer for bipolar disorder. However, little is known its effects in the prevention of suicide in patients with bipolar disorder, and recent FDA announcement indicated an increased risk of suicidality when using anti-epileptic agents such as divalproex. The aim of this study is to investigate the effect of divalproex on suicide risk in patients with bipolar disorder. METHODS A search strategy was used for the PubMed, Embase, ProQuest, ScienceDirect, Cochrane Library, ClinicalKey, Web of Science, and ClinicalTrials.gov until June 13th, 2018. Peer-reviewed observationally clinical studies in humans, investigating the association of divalproex and suicidality in patients with bipolar disorder were included. A random-effects meta-analysis was implemented to calculate the relative risk (RR) and 95% confidence intervals (CIs) for suicidality among patients receiving divalproex and those without. RESULTS Total 6 studies were included in the final meta-analysis. There was no significant difference in the incidence rates (reported as [RR]; 95% CI) of suicide attempts (0.921; 0.383-2.215) or completed suicides (0.607; 0.180-2.043) between participants receiving divalproex vs. no medication. There was no significant difference in the incidence rates of suicide attempts (0.815; 0.453-1.466) or completed suicides (1.009; 0.410-2.484) between participants receiving divalproex and carbamazepine. LIMITATIONS The significantly heterogeneous sample sources and study design amount the included trials. CONCLUSIONS Treatment with divalproex did not reduce or increase the incidence of suicide-related events in patients with bipolar disorder.

Abstract
The association of lifetime suicidal behaviors with anxiety disorders (ADs) in patients with bipolar disorder (BD) has been controversial. In this study, we hypothesized that certain types of ADs were related to the occurrence of past suicide attempts (SAs) independent of the severity of the BD, including the presence of past affective episodes. Lifetime diagnoses of BD and ADs were assessed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Axis I Disorders (SCID-I). Of the total sample of 200 patients with BD, 32.0% had at least 1 past SA. The mean number of previous hospitalizations, a history of social AD, and a history of posttraumatic stress disorder were strongly associated with past SAs in patients with bipolar I disorder. The presence of lifetime social AD was associated with lifetime SAs independent of previous depressive episodes. Therefore, we suggest that social AD itself is associated with a greater risk for SAs in patients with BD independent of the presence of depression.

Psychological and genetic risk factors associated with suicidal behavior in Korean patients with mood disorders. J Affect Disord 2018; 235:489-498.

Abstract
INTRODUCTION To prevent suicide, a nationwide important issue in Korea, understanding its etiology is essential. This study aimed to delineate the risk factors for suicidal behavior in mood disorder patients in Korea. METHODS 216 patients with mood disorders were recruited. We measured suicidal ideation (SI) and suicide attempt (SA) history and the association of six gene polymorphisms with SB: COMT (rs4680), HTR1A (rs6295), TPH1 (rs1800532), BDNF (rs6265), SLC1A3 (rs2269272), and SLC1A2 (rs4755404). RESULTS Patients in the high-SI and SA groups reported more severe depressive, hopelessness, and anxiety symptoms and lower resilience and used less social support-seeking coping than those in the non-significant SI and non-SA groups. Multivariate logistic analysis revealed that depressive disorder, depressive symptoms, poor social support, and less social support-seeking coping were significant independent predictors of suicidal ideation. After adjustment for covariates, age, alcohol consumption, and the rs4680 AA genotype in the COMT gene were associated with suicide attempt. LIMITATIONS The modest sample size and a relatively few candidate genes are limitations of the study. In addition, there is no normal control group and the retrospective evaluation of SA limits the interpretation of the causal relationship with factors affecting SA. CONCLUSIONS Suicidal behavior in Korean patients with mood disorders may be associated with younger age, alcohol consumption, depressive symptoms, poor social support, less social support-seeking coping, and the COMT rs4680 Met/Met genotype.

Abstract
UNLABELLED IntroductionBipolar disorder (BD) is a chronic, highly disabling condition associated with psychiatric/medical comorbidity and substantive morbidity, mortality, and suicide risks. In prior reports, varying parameters have been associated with suicide risk. OBJECTIVES To evaluate sociodemographic and clinical variables characterizing Italian individuals with BD with versus without prior suicide attempt (PSA). METHODS A sample of 362 Italian patients categorized as BD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM IV-TR) was assessed and divided in 2 subgroups: with and without PSA. Sociodemographic and clinical variables were compared between prior attempters and non-attempters using corrected multivariate analysis of variance (MANOVA). RESULTS More than one-fourth of BD patients (26.2%) had a PSA, with approximately one-third (31%) of these having>1 PSA. Depressive polarity at onset, higher number of psychiatric hospitalizations, comorbid alcohol abuse, comorbid eating disorders, and psychiatric poly-comorbidity were significantly more frequent (p<.05) in patients with versus without PSA. Additionally, treatment with lithium, polypharmacotherapy (≥4 current drugs) and previous psychosocial rehabilitation were significantly more often present in patients with versus without PSA. CONCLUSIONS We found several clinical variables associated with PSA in BD patients. Even though these retrospective findings did not address causality, they could be clinically relevant to better understanding suicidal behavior in BD and adopting proper strategies to prevent suicide in higher risk patients.

Abstract
BACKGROUND The risk of suicide in Bipolar Disorder (BD) has been estimated up to 20-30 times higher compared with the general population. Previous suicide attempts (SAs) represent a well-established risk factor for further attempts and for death by suicide in patients with psychiatric disorders. However, little is known about the socio-demographic and clinical profile of BD patients with a history of multiple SAs (MSAs). The present study sought to characterize BD patients with MSAs versus single suicide attempt (SSA) within a large Italian sample. METHODS An original sample of 354 bipolar patients, recruited at the University Clinic and related community services at the Department of Psychiatry, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico of Milan (Italy), was screened for the presence of previous SAs (n=95). Socio-demographic and clinical variables were then compared between patients with multiple vs single lifetime suicide attempts. RESULTS Bipolar patients with MSAs versus SSA had longer bipolar illness duration (26.9±12.6 vs 21.2±12.8years; p=0.05), and more frequently lived alone (38.5% vs 17.2%; p<0.05), had more than one psychiatric comorbidity (39.3% vs 17.5%; p=0.04), and utilized substance ingestion (e.g., overdose) (78.6% vs 47.2%, p=0.009), although the latter was the most common suicide attempt method in both groups. CONCLUSION Present findings suggest different socio-demographic and clinical characteristics in bipolar patients with MSAs versus SSA. Further investigation is needed to confirm reported data.

Abstract
BACKGROUND Suicide attempts are common in patients with bipolar disorder (BD), and consistently associated with female gender and certain unfavorable BD illness characteristics. Findings vary, however, regarding effects of BD illness subtype and yet other illness characteristics upon prior suicide attempt rates. We explored the effects of demographics and BD illness characteristics upon prior suicide attempt rates in patients stratified by BD illness subtype (i.e., with bipolar I disorder (BDI) versus bipolar II disorder (BDII)). METHODS Outpatients referred to the Stanford BD Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD Affective Disorders Evaluation. Rates of prior suicide attempt were compared in patients with and without diverse demographic and BD illness characteristics stratified by BD subtype. RESULTS Among 494 BD outpatients (mean ± SD age 35.6 ± 13.1 years; 58.3% female; 48.6% BDI, 51.4% BDII), overall prior suicide attempt rates in were similar in BDI versus BDII patients, but approximately twice as high in BDI (but not BDII) patients with compared to without lifetime eating disorder, and in BDII (but not BDI) patients with compared to without childhood BD onset. In contrast, current threshold-level suicidal ideation and lifetime alcohol use disorder robustly but less asymmetrically increased prior suicide attempt risk across BD subtypes. LIMITATIONS American tertiary bipolar disorder clinic referral sample, cross-sectional design. CONCLUSIONS Further studies are needed to assess the extent to which varying clinical characteristics of samples of patients with BDI and BDII could yield varying prior suicide attempt rates in patients with BDI versus BDII.

Abstract
OBJECTIVES The aim of the present study was to investigate various risk factors of suicidal behaviors, including the mixed features specifier, in patients with bipolar disorder. METHODS We retrospectively reviewed medical charts from 2005 to 2014. A total of 334 patients diagnosed with bipolar disorder using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision were enrolled. Subjects were categorized into two groups according to their history of suicidal behavior and the demographic and clinical characteristics of the groups were compared, including the mixed features specifier. We reevaluated the index episode using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria and classified subjects into an index episode with mixed features group and an index episode without mixed features group. Logistic regression was performed to evaluate significant risk factors associated with suicidal behavior. RESULTS Suicidal behavior had an independent relationship to mixed features at the index episode using DSM-5 criteria [odds ratio (OR)=3.39; 95% confidence interval (CI): 1.57-7.34] and number of previous depressive episodes (OR=1.62; 95% CI: 1.34-1.95) in bipolar patients. The mixed feature specifier was the strongest risk factor for suicidal behavior in the present study. CONCLUSIONS This study may help clinicians understand potential risk factors and manage bipolar disorders with suicidal behaviors. Clinicians should carefully monitor patients with bipolar disorder who exhibit numerous depressive episodes or mixed features for suicidal behavior.

Abstract
OBJECTIVE Assess reported risk of suicide attempts by patients with bipolar disorder (BD). METHOD Systematic searching yielded 101 reports from 22 countries (79 937 subjects). We analyzed for risk (%) and incidence rates (%/year) of attempts, comparing sex and diagnostic types, including by meta-analysis. RESULTS Attempt risk averaged 31.1% [CI: 27.9-34.3] of subjects, or 4.24 [3.78-4.70]%/year. In BD-I (43 studies) and BD-II subjects (30 studies), risks (29.9%, 31.4%) and incidence rates (4.01, 4.11%/year) were similar and not different by meta-analysis. Among women vs. men, risks (33.7% vs. 25.5%) and incidence (4.50 vs. 3.21%/year) were greater (also supported by meta-analysis: RR = 1.35 [CI: 1.25-1.45], P < 0.0001). Neither measure was related to reporting year, % women/study, or to onset or current age. Risks were greater with longer exposure, whereas incidence rates decreased with longer time at risk, possibly through 'dilution' by longer exposure. CONCLUSION This systematic update of international experience underscores high risks of suicide attempts among patients with BD (BD-I = BD-II; women > men). Future studies should routinely include exposure times and incidence rates by diagnostic type and sex for those who attempt suicide or not.

Abstract
OBJECTIVES Many factors influence the likelihood of suicide attempts or deaths in persons with bipolar disorder. One key aim of the International Society for Bipolar Disorders Task Force on Suicide was to summarize the available literature on the presence and magnitude of effect of these factors. METHODS A systematic review of studies published from 1 January 1980 to 30 May 2014 identified using keywords 'bipolar disorder' and 'suicide attempts or suicide'. This specific paper examined all reports on factors putatively associated with suicide attempts or suicide deaths in bipolar disorder samples. Factors were subcategorized into: (1) sociodemographics, (2) clinical characteristics of bipolar disorder, (3) comorbidities, and (4) other clinical variables. RESULTS We identified 141 studies that examined how 20 specific factors influenced the likelihood of suicide attempts or deaths. While the level of evidence and degree of confluence varied across factors, there was at least one study that found an effect for each of the following factors: sex, age, race, marital status, religious affiliation, age of illness onset, duration of illness, bipolar disorder subtype, polarity of first episode, polarity of current/recent episode, predominant polarity, mood episode characteristics, psychosis, psychiatric comorbidity, personality characteristics, sexual dysfunction, first-degree family history of suicide or mood disorders, past suicide attempts, early life trauma, and psychosocial precipitants. CONCLUSION There is a wealth of data on factors that influence the likelihood of suicide attempts and suicide deaths in people with bipolar disorder. Given the heterogeneity of study samples and designs, further research is needed to replicate and determine the magnitude of effect of most of these factors. This approach can ultimately lead to enhanced risk stratification for patients with bipolar disorder.

Abstract
BACKGROUND Both individuals with bipolar (BD) and those with alcohol (AUD) and other substance (SUD) use disorders are likely to attempt suicide. Comorbidity of BD and AUD/SUD may increase the likelihood of suicide attempts. We conducted a meta-analysis to estimate the association of comorbid AUD/SUD and suicide attempts in subjects with BD in the literature to date. METHODS Electronic databases through January 2013 were searched. Studies reporting rates of suicide attempts in people with co-occurring BD and AUD/SUD were retrieved. Comorbid AUD and SUD and suicide attempts rates as well as demographic, clinical, and methodological variables were extracted from each publication or obtained directly from its authors. RESULTS Twenty-nine of 222 studies assessed for eligibility met the inclusion criteria, comprising a total of 31,294 individuals with BD, of whom 6308 (20.1%) had documented suicide attempts. There were consistent findings across the studies included. As compared to controls, subjects with BD and comorbid AUD/SUD were more likely to attempt suicide. The cross-sectional association estimates showed random-effects pooled crude ORs of 1.96 (95% CI=1.56-2.47; p<0.01), 1.72 (95% CI=1.52-1.95; p<0.01), and 1.77 (95% CI=1.49-2.10; p<0.01), for combined AUD/SUD, AUD, and SUD. There was no publication bias and sensitivity analyses based on the highest quality studies confirmed core results. LIMITATIONS The effects of the number and the type of suicide attempts could not be investigated due to insufficient information. CONCLUSIONS Comorbid AUD and SUD in individuals with BD are significantly associated with suicide attempts. Individuals with this comorbidity should be targeted for intensive suicide prevention efforts.

Abstract
OBJECTIVES Bipolar disorder is associated with a high risk of suicide attempts and suicide death. The main objective of the present study was to identify and quantify the demographic and clinical correlates of attempted and completed suicide in people with bipolar disorder. METHODS Within the framework of the International Society for Bipolar Disorders Task Force on Suicide, a systematic review of articles published since 1980, characterized by the key terms bipolar disorder and 'suicide attempts' or 'suicide', was conducted, and data extracted for analysis from all eligible articles. Demographic and clinical variables for which ≥ 3 studies with usable data were available were meta-analyzed using fixed or random-effects models for association with suicide attempts and suicide deaths. There was considerable heterogeneity in the methods employed by the included studies. RESULTS Variables significantly associated with suicide attempts were: female gender, younger age at illness onset, depressive polarity of first illness episode, depressive polarity of current or most recent episode, comorbid anxiety disorder, any comorbid substance use disorder, alcohol use disorder, any illicit substance use, comorbid cluster B/borderline personality disorder, and first-degree family history of suicide. Suicide deaths were significantly associated with male gender and first-degree family history of suicide. CONCLUSIONS This paper reports on the presence and magnitude of the correlates of suicide attempts and suicide deaths in bipolar disorder. These findings do not address causation, and the heterogeneity of data sources should limit the direct clinical ranking of correlates. Our results nonetheless support the notion of incorporating diagnosis-specific data in the development of models of understanding suicide in bipolar disorder.

Abstract
OBJECTIVE Bipolar disorder is associated with high risk of self-harm and suicide. We wanted to investigate risk factors for attempted suicide in bipolar patients. METHOD This was a cohort study of 6086 bipolar patients (60% women) registered in the Swedish National Quality Register for Bipolar Disorder 2004-2011 and followed-up annually 2005-2012. Logistic regression was used to calculate adjusted odds ratios for fatal or non-fatal attempted suicide during follow-up. RESULTS Recent affective episodes predicted attempted suicide during follow-up (men: odds ratio = 3.63, 95% CI = 1.76-7.51; women: odds ratio = 2.81, 95% CI = 1.78-4.44), as did previous suicide attempts (men: odds ratio = 3.93, 95% CI = 2.48-6.24; women: odds ratio = 4.24, 95% CI = 3.06-5.88) and recent psychiatric inpatient care (men: odds ratio = 3.57, 95% CI = 1.59-8,01; women: odds ratio = 2.68, 95% CI = 1.60-4.50). Further, those with many lifetime depressive episodes were more likely to attempt suicide. Comorbid substance use disorder was a predictor in men; many lifetime mixed episodes, early onset of mental disorder, personality disorder, and social problems related to the primary group were predictors in women. CONCLUSION The principal clinical implication of the present study is to pay attention to the risk of suicidal behaviour in bipolar patients with depressive features and more severe or unstable forms of the disorder.

Abstract
Bipolar patients (BP) are at high risk of suicide. Causal factors underlying suicidal behavior are still unclear. However, it has been shown that lithium has antisuicidal properties. Genes involved in its putative mechanism of action such as the phosphoinositol and the Wnt/β-catenine pathways could be considered candidates for suicidal behavior (SB). Our aim was to investigate the association of the IMPA1 and 2, INPP1, GSK3α and β genes with suicidal behavior in BP. 199 BP were recruited. Polymorphisms at the IMPA1 (rs915, rs1058401 and rs2268432) and IMPA2 (rs66938, rs1020294, rs1250171 and rs630110), INPP1 (rs3791809, rs4853694 and 909270), GSK3α (rs3745233) and GSK3β (rs334558, rs1732170 and rs11921360) genes were genotyped. All patients were grouped and compared according to the presence or not of history of SB (defined as the presence of at least one previous suicidal attempt). Single SNP analyses showed that suicide attempters had higher frequencies of AA genotype of the rs669838-IMPA2 and GG genotype of the rs4853694-INPP1gene compared to non-attempters. Results also revealed that T-allele carriers of the rs1732170-GSK3β gene and A-allele carriers of the rs11921360-GSK3β gene had a higher risk for attempting suicide. Haplotype analysis showed that attempters had lower frequencies of A:A haplotype (rs4853694:rs909270) at the INPP1 gene. Higher frequencies of the C:A haplotype and lower frequencies of the A:C haplotype at the GSK-3β gene (rs1732170:rs11921360) were also found to be associated to SB in BP. Therefore, our results suggest that genetic variability at IMPA2, INPP1 and GSK3β genes is associated with the emergence of SB in BP.

Abstract
BACKGROUND Few studies have investigated symptomatic subtypes of depression and their correlates by gender. METHODS Data are from the São Paulo Megacity Mental Health Survey. Symptom profiles of 1207 subjects (864 women; 343 men) based upon symptoms of the worst depressive episode in lifetime were examined through latent class analysis. Correlates of gender-specific latent classes were analyzed by logistic regression. RESULTS For both men and women, a 3-class model was the best solution. A mild class was found in both genders (41.1% in women; 40.1% in men). Gender differences appeared in the most symptomatic classes. In women, they were labeled melancholic (39.3%) and atypical (19.5%), differing among each other in somatic/vegetative symptoms. The melancholic class presented inhibition and eating/sleeping symptoms in the direction of decreasing, whereas the atypical class had increased appetite/weight, and hypersomnia. For men, symptoms that differentiate the two most symptomatic classes were related to psychomotor activity: a melancholic/psychomotor retarded (40.4%) and agitated depression (19.6%). The highest between-class proportion of agitation and racing thoughts was found among men in the agitated class, with similarity to bipolar mixed state. LIMITATIONS Analyses were restricted to those who endorsed questions about their worst lifetime depressive episode; the standardized assessment by lay interviewers; the small male sample size. CONCLUSIONS The construct of depression of current classifications is heterogeneous at the symptom level, where gender different subtypes can be identified. These symptom profiles have potential implications for the nosology and the therapeutics of depression.

Abstract
The social and economic impact of mood disorders and suicide is extremely high and may be even higher in coming years, and yet, research in mental health is largely underfunded. This report summarizes the most recent data concerning the epidemiology and burden of depression and suicide, and underlines the most recent initiatives to identify the barriers to effective treatment and prevention of mood disorders. Global cooperation and networks of research networks are proposed. Progress in the understanding of the pathophysiology and subtypes of depression, technological advances, emphasis on early prediction of response and prevention, and a paradigm shift in drug development are crucial to overcome the current challenges posed by increasing rates of depression and suicide.

Abstract
BACKGROUND Suicide is one of the leading causes of death and a major public health problem worldwide, and the majority of suicide attempters and completers suffer from some major affective disorder at the time of their death, which, in the majority of cases is unrecognized, under- or misdiagnosed and untreated. METHODS Based on a systematic literature search, the authors give a detailed and critical overview of established risk factors of suicide in bipolar disorder. RESULTS Among affective disorders, bipolar disorder carries the highest risk of suicide, yet not all bipolar patients commit or even attempt suicide during their illness. While the general suicide risk factors also apply for bipolar disorders, there are several disease-specific risk factors as well which should be taken into account when evaluating suicide risk in case of patients. CONCLUSION It is crucial to identify suicide risk factors in bipolar disorder to be able to differentiate those patients within this already increased-risk illness group who are at especially high risk and therefore to allow for better prediction and prevention of suicidal acts.

Abstract
OBJECTIVE Attempted suicide and death due to suicide are not uncommon among patients with bipolar disorder. Although some risk factors for suicidality in bipolar patients have been identified, little is known about hopelessness and other possible trait or diathesis-related factors. Consequently, the objective of this study was to investigate variables associated with suicidal risk in clinically nonsyndromal bipolar patients. METHODS A sample of 102 outpatients with a diagnosis of bipolar disorder according to International Classification of Diseases, 10th Revision criteria during nonsyndromal stage were evaluated. On the basis of suicidal history, patients were divided into suicide attempt, suicidal ideation, and nonsuicidal groups. Sociodemographic, clinical, and psychopathological variables were assessed. RESULTS As compared with the nonsuicidal group, female sex, combined psychopharmacologic treatment, and hopelessness were independently associated with suicide attempt. Hopelessness and insight into having a mental disorder were independently associated with history of suicidal ideation. CONCLUSIONS Patients with bipolar disorder and suicidal history are characterized by the presence of hopelessness, which probably confers greater vulnerability for suicidal behavior in the presence of stress factors. This identification of the risk profile for suicidal behavior in nonsyndromal bipolar patients adds complementary information to risk factors established for suicidality during acute phases of the disease, allows for differentiated preventive and treatment approaches of patients at risk, and suggests psychotherapy as an advisable intervention in this group of patients.

Abstract
OBJECTIVE An association between allergic disease and depression has been consistently reported, but whether the key mediating ingredients are predominantly biological, psychological, or mere artifacts remains unknown. In the current study, we examined a hypothesized relationship between allergen-specific immunoglobulin E (IgE) status and changes in allergy symptoms with worsening in depression scores. METHODS In patients with recurrent mood disorders, we individually coupled sensitization to specific seasonal aeroallergens (as assessed by allergen-specific IgE) with temporal windows of exposure to aeroallergens (low versus high tree or ragweed pollen counts, measured according to the National Allergy Bureau guidelines). We compared Structured Interview Guide for the Hamilton Depression Rating Scale-Seasonal Affective Disorder Version (SIGH-SAD) depression score changes in 41 patients with mood disorders [25 with major depression and 16 with bipolar I disorder, diagnosed by Structured Clinical Interview for DSM (SCID)] seropositive for tree or ragweed pollen-specific IgE antibody versus 53 patients with mood disorders (30 with major depression and 23 with bipolar I disorder) seronegative for aeroallergen-specific IgE. RESULTS Worsening in total depressive scores from low to high pollen exposure was greater in allergen-specific IgE-positive patients as compared to allergen-specific IgE antibody-negative patients (p = 0.01). When stratified by polarity, the association was significant only in patients with bipolar I disorder (p = 0.004). This relationship was resilient to adjustment for changes in allergy symptom scores. CONCLUSION To our knowledge, this is the first report of coupling a molecular marker of vulnerability (allergen-specific IgE) with a specific environmental trigger (airborne allergens) leading to exacerbation of depression in patients with bipolar I disorder.

Abstract
OBJECTIVE To address the best available scientific evidence on the role of child sexual abuse in the etiology of suicide and non-suicidal self-injury. METHOD Seven databases were searched, supplemented with hand-search of reference lists from retrieved papers. The author and a psychiatrist independently evaluated the eligibility of all studies identified, abstracted data, and assessed study quality. Disagreements were resolved by consensus. RESULTS Four reviews, including about 65,851 subjects from 177 studies, were analyzed. There is evidence that child sexual abuse is a statistically significant, although general and non-specific, risk factor for suicide and non-suicidal self-injury. The relationship ranges from small to medium in magnitude and is moderated by sample source and size. Certain biological and psychosocial variables, such as serotonin hypoactivity and genes, family dysfunction, other forms of maltreatment, and some personality traits and psychiatric disorders, may either act independently or interact with child sexual abuse to promote suicide and non-suicidal self-injury in abuse victims, with child sexual abuse conferring additional risk, either as a 'distal' and indirect cause or as a 'proximal' and direct cause. CONCLUSION Child sexual abuse should be considered one of the several risk factors for suicide and non-suicidal self-injury and included in multifactorial etiological models.

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
OBJECTIVE To report on the presence of current and lifetime eating disorders (ED) in a well-defined sample of 137 female individuals with bipolar disorder type I. METHODS Trained psychiatrists interviewed the patients, and the diagnoses of BD and comorbidities were confirmed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Axis I Disorders. Clinical and demographic characteristics of both groups (group with ED vs. group without ED) were compared. RESULTS Female patients with ED had an earlier onset of BD and an increased number of mood episodes, predominantly depressive. Women in the ED group also had higher rates of comorbidity with substance use disorders and anxiety disorders and reported a history of suicide attempts more frequently than women without ED. CONCLUSION The presence of ED is a correlate of severity of BD type I, and interventions should be developed to minimize distress and suicide risk and to improve treatment outcome.

Abstract
UNLABELLED Gomes FA, Kauer-Sant'Anna M, Magalhães PV, Jacka FN, Dodd S, Gama CS, Cunha Â, Berk M, Kapczinski F. Obesity is associated with previous suicide attempts in bipolar disorder. OBJECTIVE There is a paucity of data about risk factors for suicide attempts in bipolar disorder. The aim of this study is to examine the association between suicide attempts and obesity in people with bipolar disorder. METHODS Two hundred fifty-five DSM-IV out-patients with bipolar disorder were consecutively recruited from the Bipolar Disorder Program at Hospital das Clínicas de Porto Alegre and the University Hospital at the Universidade Federal de Santa Maria, Brazil. Diagnosis and clinical variables were assessed with Structured Clinical Interview for DSM-IV-axis I (SCID I) and Program structured protocol. History of suicide attempts was obtained from multiple information sources including patients, relatives and review of medical records. Patients with body mass index (BMI) ≥ 30 were classified as obese. RESULTS Over 30% of the sample was obese and over 50% had a history of suicide attempt. In the multivariate model, obese patients were nearly twice (OR = 1.97, 95% CI: 1.06-3.69, p = 0.03) as likely to have a history of suicide attempt(s). CONCLUSION Our results emphasise the relevance of obesity as an associated factor of suicide attempts in bipolar disorder. Obesity may be seen as correlate of severity and as such, must be considered in the comprehensive management of bipolar patients.

Abstract
OBJECTIVE Previous studies of atypical depression have been conducted in Western communities. There has been no community-based epidemiological study of atypical depression that covers the entire spectrum of bipolar disorders. The aim of the present study was to examine the 12 month prevalence of atypical depression and the differences in demographic and clinical profiles between depressed patients with and without atypical symptoms in the Chinese adult population of Hong Kong. METHOD A random sample of 3016 Chinese adults completed a telephone-based structured interview that examined their 12 month prevalence of major depressive episode. Atypical depression was defined as major depressive episode with hypersomnia and increased weight or appetite. Major depressive episode with and without atypical symptoms were compared on sociodemographic variables, number of depressive and manic/hypomanic symptoms, proportion of having lifetime mania/hypomania, suicidality, family psychiatric history, help-seeking behaviour, level of distress and role impairment. RESULTS The 12 month prevalence of atypical depression was 1.3%. Compared to non-atypical depression, atypical depression was associated with female gender, soft (subthreshold) bipolar II disorder, family psychiatric history, higher suicidality, more help-seeking from psychiatrists, and more depressive and manic/hypomanic symptoms. There was no difference in levels of distress or impairment. CONCLUSIONS Although limited by the lack of detailed information on comorbidity, bipolar family history, and age of onset, the findings support the hypothesis that atypical depression among Chinese people in Hong Kong exhibited prevalence and correlates similar to those found in Western epidemiological and clinical studies. Further research is warranted to examine its association with hypomania and how atypical depression may occupy a nosological position between typical unipolar depression and bipolar spectrum disorders.
