Abstract
OBJECTIVE The aim of our study was to investigate, in bipolar patients, whether affect lability was associated with suicidal ideation incidence during 2-year follow-up, and which subtype of affect lability was associated with suicidal ideation. METHOD A total of 319 euthymic or mildly depressed bipolar outpatients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups according to the occurrence of suicidal ideation during a 2-year follow-up. Affect lability was assessed by the French version of the Affect Lability Scale. RESULTS Bipolar patients with high affect lability were more likely to report suicidal ideation during follow-up, even after adjustment for age, study level, rapid cycling, current depression level, anxiety disorder, and lifetime history SA (OR = 2.47; 95% CI [1.15-5.30], P = 0.01). The risk of suicidal ideation increased with the level of affect lability. More specifically, the propensity to switch from neutral to elation affect, from anxious to depressive affect (or inversely), and from neutral to anger affect predicted suicidal ideation. CONCLUSION Reducing affective lability could become a new therapeutic target of suicidal prevention in bipolar disorder.

Abstract
Worldwide, suicide is a leading cause of death. Although a sizable proportion of deaths by suicide may be preventable, it is well documented that despite major governmental and international investments in research, education and clinical practice suicide rates have not diminished and are even increasing among several at-risk populations. Although nonhuman animals do not engage in suicidal behavior amenable to translational studies, we argue that animal model systems are necessary to investigate candidate endophenotypes of suicidal behavior and the neurobiology underlying these endophenotypes. Animal models are similarly a critical resource to help delineate treatment targets and pharmacological means to improve our ability to manage the risk of suicide. In particular, certain pathophysiological pathways to suicidal behavior, including stress and hypothalamic-pituitary-adrenal axis dysfunction, neurotransmitter system abnormalities, endocrine and neuroimmune changes, aggression, impulsivity and decision-making deficits, as well as the role of critical interactions between genetic and epigenetic factors, development and environmental risk factors can be modeled in laboratory animals. We broadly describe human biological findings, as well as protective effects of medications such as lithium, clozapine, and ketamine associated with modifying risk of engaging in suicidal behavior that are readily translatable to animal models. Endophenotypes of suicidal behavior, studied in animal models, are further useful for moving observed associations with harmful environmental factors (for example, childhood adversity, mechanical trauma aeroallergens, pathogens, inflammation triggers) from association to causation, and developing preventative strategies. Further study in animals will contribute to a more informed, comprehensive, accelerated and ultimately impactful suicide research portfolio.

Abstract
Disease due to non-tuberculous mycobacteria (NTM) is common in fish. Current recommendations focus on outbreak management by depopulating entire fish stocks and disinfecting tanks. Treatment is not advocated. Treatment may be appropriate, however, where individual, valuable fish are concerned. ZSL London Zoo managed an outbreak of mycobacteriosis in a valuable group of imported F1 captive-bred Australian lungfish (Neoceratodus fosteri) by depopulation, isolation, extensive testing and daily oral antibiotic treatment. Four species of Mycobacterium (M. marinum, M. fortuitum, M. chelonae and M. peregrinum) were involved in this outbreak, each with unique antibiotic sensitivities. Triple therapy with rifampicin, doxycycline and enrofloxacin for 8 months was the most effective antibiotic combination, resulting in full disease resolution. No side effects were noted and, more than 18 months post-treatment, no recurrence had occurred. This is the first report of mycobacterial disease in lungfish and the first report of a polymycobacterial outbreak in fish involving these four species of Mycobacterium. This report demonstrates the value of extensive isolation and identification. Also, as therapies currently advised in standard texts did not reflect the antibiotic sensitivity of the NTM found in the fish reported here, we recommend that antibiotic treatment should always be based on sensitivity testing.

Abstract
BACKGROUND Tobacco smoking increases the global burden of bipolar disorder (BD). We examined markers of physical and mental health that are associated with tobacco smoking, controlling for confounders that have not always been considered in previous studies of BD. METHODS Over 600 individuals with BD I or II referred to the French Network for bipolar disorder (FACE-BD) who completed standardized assessments, and could be reliably classified as current (CS) or former smokers (FS), were compared with those who were never smokers (NS) on: BD symptom load and psychiatric comorbidities; prevalence of alcohol and substance use disorders (ASUD); medication usage; functioning and physical health parameters. The bivariate and multivariate analyses took into account age and gender. RESULTS 300 cases (49%) were CS, 78 (13%) FS and 238 (39%) had never smoked. Rates were similar across genders regardless of BD subtype. Compared with NS, CS were more likely to have an ASUD (Odds Ratio (OR) 5.18), BD I (OR 2.09), and lower abdominal obesity (OR 0.97), and FS were more likely to have an ASUD (OR 6.32) and higher abdominal obesity (OR 1.03). LIMITATIONS The sample comprised of white Europeans; the FS subgroup was relatively small and we did not apply any statistical correction for the bivariate analyses. CONCLUSIONS The increased risk of physical and mental health burden in CS and FS compared to NS represents avoidable morbidity in BD. This study offers support to the argument that individuals with BD should be routinely offered support to prevent or stop tobacco smoking.

Abstract
OBJECTIVES Suicidal behaviour (SB) entered the DSM-5, underlying a specific biological vulnerability. Then, recent findings suggested a possible role of the immune system in SB pathogenesis. The objective of this review is to present these main immune factors involved in SB pathogenesis. METHODS We conducted a review using Preferred Reporting Items for Systematic reviews and Meta-Analysis criteria, and combined ("Inflammation") AND ("Suicidal ideation" OR "Suicidal attempt" OR "suicide"). RESULTS Post mortem studies demonstrated associations between suicide and inflammatory cytokines in the orbitofrontal cortex, a brain region involved in suicidal vulnerability. Also, microgliosis and monocyte-macrophage system activation may be a useful marker of suicide neurobiology. Kynurenine may influence inflammatory processes, and related molecular pathways may be involved in SB pathophysiology. Few recent studies associated inflammatory markers with suicidal vulnerability: serotonin dysfunction, impulsivity and childhood trauma. Interestingly, the perception of threat that leads suicidal individuals to contemplate suicide may activate biological stress responses, including inflammatory responses. CONCLUSIONS Translational projects would be crucial to identify a specific marker in SB disorders, to investigate its clinical correlations, and the interaction between inflammatory cytokines and monoamine systems in SB. These researches might lead to new biomarkers and novel directions for therapeutic strategies.

Abstract
Juvenile systemic lupus erythematosus (JSLE) represents 15—20% of all SLE cases. The leading presenting symptoms of JSLE are constitutional and not specific such as fatigue, headache, weight loss or mood swings. They are also encountered in healthy adolescents, which explains frequent diagnosis delay. The frequency of irreversible damage is high in JSLE and involves especially the renal, musculoskeletal and neuropsychiatric systems. Although the overall prognosis has markedly improved, thanks to earlier diagnosis and new therapeutic approaches, cardiovascular, hematological events and chronic renal failure remain severe, and constitute the main disease-related causes of death. Treatment is based on hydroxycloroquine and corticosteroids. Immunosuppressive agents must be discussed to decrease the duration of corticosteroids use. New drugs and monoclonal antibodies targeting B-cells and B-cell related cytokines are being evaluated with encouraging results. Management of JSLE has to challenge three objectives: controlling disease progression, obtaining patient's adherence to treatment, and preventing consequences of medication side effects on growth, puberty, development and fertility. Patients' quality of life and psychosocial development have also to be taken into account, as well as the organization of a successful transition from paediatric to adult care. Lupus (2007) 16, 606—612.

Abstract
BACKGROUND Attempts to predict suicidal behavior within high-risk populations have so far shown insufficient accuracy. Although several psychosocial and clinical features have been consistently associated with suicide attempts, investigations of latent structure in well-characterized populations of suicide attempters are lacking. METHODS We analyzed a sample of 1,009 hospitalized suicide attempters that were recruited between 1999 and 2012. Eleven clinically relevant items related to the characteristics of suicidal behavior were submitted to a Hierarchical Ascendant Classification. Phenotypic profiles were compared between the resulting clusters. A decisional tree was constructed to facilitate the differentiation of individuals classified within the first 2 clusters. RESULTS Most individuals were included in a cluster characterized by less lethal means and planning ("impulse-ambivalent"). A second cluster featured more carefully planned attempts ("well-planned"), more alcohol or drug use before the attempt, and more precautions to avoid interruptions. Finally, a small, third cluster included individuals reporting more attempts ("frequent"), more often serious or violent attempts, and an earlier age at first attempt. Differences across clusters by demographic and clinical characteristics were also found, particularly with the third cluster whose participants had experienced high levels of childhood abuse. CONCLUSIONS Cluster analysis consistently supported 3 distinct clusters of individuals with specific features in their suicidal behaviors and phenotypic profiles that could help clinicians to better focus prevention strategies.

Abstract
Deficits in emotional processes are often observed by clinicians in anorexia nervosa and may have an impact on social functioning. Recognition of emotion was mostly investigated using visual stimuli as faces of emotional scenes. Only one study (Kucharska-Pietura et al., 2004) demonstrated impairments in emotional prosody using positive and negative valenced stimuli. However, this study did not provide a highlight for the identification of emotional bias (for example, to recognize an intense fear in a friendly voice). The aim of this study is to better understand the recognition of emotional prosody in anorexia nervosa using a wide range of positive, negative and neutral stimuli (Belin et al., 2008).In order to test emotion recognition biases in emotional prosody, we exposed 15 patients with anorexia nervosa and 15 healthy controls (HCs) to emotional vocal tasks asking them to rate emotional intensity on visual analog scales. In addition, we assessed clinical symptomatology and cognitive functioning for all participants.We showed that patients with anorexia nervosa provided higher intensity ratings on the non-target scales (e.g., surprise scale for fear stimuli) than HCs for sadness, fear and neutral voices. Furthermore, with the exception of neutral vocal stimuli, they provided the same intensity ratings on the target scales as the HCs.These findings suggested a bias in the processing of emotional prosody and may impact the social functioning of patients with anorexia nervosa. The bias may result from a sensorial deficit or a high-order cognitive dysfunction and have to be investigated in future studies.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Recent experimental data suggest that circulating serotonin interacts with bone metabolism, although this is less clear in humans. This study investigated whether serum serotonin interferes with bone metabolism in young women with anorexia nervosa (AN), a clinical model of energy deprivation. Serum serotonin, markers of bone turnover [osteocalcin (OC), procollagen type I N-terminal propeptide (PINP), type I-C telopeptide breakdown products (CTX)], leptin, soluble leptin receptor (sOB-R), and insulin-like growth factor-1 (IGF-1) and its binding protein (IGFBP-3) were assessed. Whole body, spine, hip, and radius areal bone mineral density BMD (aBMD) were assessed by dual-energy X-ray absorptiometry in 21 patients with AN and 19 age-matched controls. Serum serotonin, leptin, IGF-1, IGFBP-3, OC, PINP, and aBMD at all sites, radius excepted, were significantly reduced in AN whereas CTX and sOB-R were increased compared with controls. Serum serotonin levels were positively correlated with weight, body mass index, whole body fat mass, leptin, and IGF-1, and negatively with CTX for the entire population. Low serum serotonin levels are observed in patients with AN. Although no direct link between low serum serotonin levels and bone mass was identified in these patients, the negative relationship between serotonin and markers of bone resorption found in all population nevertheless suggests the implication of serotonin in bone metabolism. Impact of low serum serotonin on bone in AN warrants further studies.

Abstract
AIMS Tobacco dependence and suicidal behaviors have been repeatedly associated in several studies but their relationship is still unclear. We aim to investigate, specifically, the association between the level of tobacco dependence and the severity of suicidal outcomes among suicide attempters, as well as the relationship of impulsivity with both conditions. METHODS We examined a cross-sectional sample of 542 adult suicide attempters to compare the characteristics of the attempts depending on the level of tobacco dependence, which was assessed with the Fagerstrom test. RESULTS Smokers with heavy dependence (Fagerstrom ≥7) made more attempts and reached higher medical lethality compared to non-smokers. Smokers with moderate dependence were not associated with features of severity in the suicide attempts. The combination of high impulsivity and heavy tobacco dependence showed an additive effect on the number of suicide attempts. CONCLUSIONS A high or very high level of tobacco dependence could indicate a specific vulnerability leading to more severe suicide attempts. Impulsive attempters with heavy tobacco dependence were particularly at risk.

Abstract
UNLABELLED Low bone mass is a consequence of anorexia nervosa (AN). This study assessed the effects of energy deficiency on various bone and hormonal parameters. The interrelationships between energy deficiency and bone remodelling, glucose homeostasis and adipokines underscore the importance of preventing energy deficiency to limit demineralisation and hormonal alterations in AN patients. INTRODUCTION Low areal bone mineral density (aBMD) is a well-known consequence of AN. However, the impact of reduced energy expenditure on bone metabolism is unknown. This study assessed the effects of energy deficiency on bone remodelling and its potential interactions with glucose homeostasis and adipose tissue-derived hormones in AN, a clinical model for reduced energy expenditure. METHODS Fifty women with AN and 50 age-matched controls (mean age 18.1 ± 2.7 and 18.0 ± 2.1 years, respectively) were enrolled. aBMD was determined with DXA. Resting energy expenditure (REEm), a marker of energy status, was indirectly assessed by calorimetry. Bone turnover markers, undercarboxylated osteocalcin (ucOC), parameters of glucose homeostasis, adipokines and growth factors were concomitantly evaluated. RESULTS AN patients presented low aBMD at all bone sites. REEm, bone formation markers, ucOC, glucose, insulin, HOMA-IR, leptin and IGF-1 were significantly reduced, whereas the bone resorption marker, leptin receptor (sOB-R) and adiponectin were elevated in AN compared with CON. In AN patients, REEm was positively correlated with weight, BMI, whole body (WB) fat mass, WB fat-free soft tissue, markers of bone formation, glucose, insulin, HOMA-IR, leptin and IGF-1 and negatively correlated with the bone resorption marker and sOB-R. Biological parameters, aBMD excepted, appeared more affected by the weight variation in the last 6 months than by the disease duration. CONCLUSIONS The strong interrelationships between REEm and bone remodelling, glucose homeostasis and adipokines underscore the importance of preventing energy deficiency to limit short- and long-term bone demineralisation and hormonal alterations in AN patients.

Abstract
BACKGROUND Impaired decision-making is a potential neurocognitive phenotype of eating disorders. It is therefore important to disentangle the decision-making deficits associated with the eating disorder subtypes and determine whether this putative impairment is a state or trait marker of the disease or more related to starvation. We systematically reviewed the literature on decision-making in eating disorders and conducted a meta-analysis to explore its role in anorexia nervosa (AN), bulimia nervosa (BN) and binge-eating disorder (BED). METHOD A search of the Medline and EMBASE databases and article references was performed. A total of 23 studies (2044 participants) met the selection criteria. When the Iowa gambling task (IGT) was used in at least three of the studies, a meta-analysis was run. RESULTS IGT performance was significantly worse in patients with an eating disorder diagnosis (AN, BN or BED) compared with healthy controls, indicating that eating disorders have a negative effect on decision-making. Hedges' g effect sizes were moderate to large (-0.72 in AN, -0.62 in BN, and -1.26 in BED). Recovered AN patients had IGT scores similar to those of healthy controls. Restrictive AN patients had significantly lower IGT net scores than purging AN patients, and both AN subtypes had worse performances than healthy controls. Age and body mass index did not explain results. CONCLUSIONS Decision-making was significantly altered in patients with eating disorders. Poor decision-making was more pronounced during the acute phase than in the recovered state of AN. Nutritional status during the acute phase of the disease did not seem to influence decision-making skills.

Abstract
ContexteLes conduites suicidaires (CS) constituent un problème de santé publique majeur à travers le monde. Elles présentent une vulnérabilité propre, et sont maintenant considérées comme une entité diagnostique indépendante dans le DSM5. La thérapie d’acceptation et d’engagement (ACT) est une thérapie intégrative ayant démontré son utilité dans une grande variété de troubles psychiatriques, à travers une diminution de l’évitement expérientiel et une amélioration de la flexibilité psychologique (socles communs à l’ensemble des troubles psychiatriques) .InnovationNous avons conduit une étude pilote suggérant la faisabilité de la thérapie ACT, sous forme de groupes, chez les patients suicidants (CHRU de Montpellier, Pr Courtet) . À travers la présentation des processus thérapeutiques utilisés dans la thérapie ACT, nous aborderons les hypothèses d’action de la thérapie ACT dans les conduites suicidaires. Puis nous présenterons l’étude IMPACT, en cours de réalisation dans le service urgences et post-urgences psychiatriques (CHRU de Montpellier, Pr Courtet). Il s’agit de la première étude contrôlée randomisée recherchant des biomarqueurs neuroanatomiques et fonctionnels de réponse à la thérapie ACT chez des patients ayant un trouble des conduites suicidaires. Nous aborderons enfin, de façon pratique, comment présenter la thérapie ACT à un patient, à travers une matrice . Il s’agit d’une analyse fonctionnelle permettant de faire percevoir au patient le fonctionnement actuel dans lequel il se sent enlisé, de mettre en lumière ce qui est important dans sa vie, et donc d’avoir un outil motivationnel simple et efficace pour l’accompagner vers le changement.PerspectivesLa thérapie ACT semble être une thérapie prometteuse dans la prise en charge des conduites suicidaires. L’étude IMPACT servira à accroître les connaissances sur les conduites suicidaires par l’identification de biomarqueurs de réponse thérapeutique et la mise en évidence des régions cérébrales associées aux processus thérapeutiques.

Abstract
Suicide is a leading cause of death worldwide. Identifying biomarkers will help enhance our understanding of suicidal pathophysiology and improve its prevention. Therefore, we investigated CRP levels in 600 depressed inpatients: 520 patients had a lifetime history of suicide attempts and 80 patients did not have any history of suicide attempts. For all patients, we assessed socio-demographic features, lifetime Axis I DSM-IV diagnoses, depression intensity, suicidal ideation, characteristics of suicidal history, and history of childhood trauma. The day following admission, fasting blood tests yielded samples collected for the measurement of high sensitivity hs-CRP. CRP levels were associated with a history of suicide attempts. The risk of suicide attempts increased with higher levels of CRP in a dose-response way before and after adjustments for age, gender, chronic diseases, addiction and anxiety comorbidities, antidepressants use, smoking status and sexual abuse. Noteworthy, the association between CRP levels and history of suicide attempts remained significant after having excluded patients with chronic diseases. There was no significant difference in CRP levels between patients who attempted suicide more or less than a week before plasma sampling, and no significant difference in CRP levels was evidenced between high vs low suicidal ideation. In conclusion, this is the first study suggesting that CRP may be a trait marker for suicidal vulnerability by associating CRP levels and a lifetime history of suicide attempts in depressed inpatients. Therefore, determining the inflammatory marker profile of individuals exhibiting suicidal behaviors could be relevant for anticipating behaviors and refining new therapeutic opportunities.

Abstract
BACKGROUND The aim of our study was to investigate, in bipolar patients, the association between tobacco status (use and dependence) and history of suicide attempt, and to assess the possible role of inflammation as a missing link in the association between smoking status and history of suicide attempt. METHODS A total of 453 adult bipolar out-patients recruited in the French FondaMental Advanced Centres of Expertise for Bipolar Disorder were divided into two subgroups: 274 patients without past history of suicide attempt (non-SA), and 179 patients with a past history of suicide attempt (SA). Tobacco use and dependence, psychiatric and somatic comorbidities, history of childhood abuse, family history of suicide were assessed. Fasting blood tests yielded samples collected for the measurement of high sensitivity (hs-)CRP. RESULTS The risk of suicide attempt increased with smoking dependence. Notably, bipolar patients with a history of suicide attempt were three times more likely to have severe tobacco dependence, independently of confounding factors. However, we failed to find arguments promoting the hypothesis of inflammatory markers (through hs-CRP measure) in the link between tobacco dependence and suicidal behavior. CONCLUSIONS We found a significant association between severe tobacco dependence and history of suicide attempt, but not with level of CRP, independently of confusing factors. Longitudinal studies taken into account all these potential confusing factors are needed to confirm our results.

Abstract
Bipolar disorder is associated with impaired decision-making. Little is known about how treatment, especially lithium, influences decision-making abilities in bipolar patients when euthymic. We aimed at testing for an association between lithium medication and decision-making performance in remitted bipolar patients. Decision-making was measured using the Iowa Gambling Task in 3 groups of subjects: 34 and 56 euthymic outpatients with bipolar disorder, treated with lithium (monotherapy and lithium combined with anticonvulsant or antipsychotic) and without lithium (anticonvulsant, antipsychotic and combination treatment), respectively, and 152 matched healthy controls. Performance was compared between the 3 groups. In the 90 euthymic patients, the relationship between different sociodemographic and clinical variables and decision-making was assessed by stepwise multivariate regression analysis. Euthymic patients with lithium (p=0.007) and healthy controls (p=0.001) selected significantly more cards from the safe decks than euthymic patients without lithium, with no significant difference between euthymic patients with lithium and healthy controls (p=0.9). In the 90 euthymic patients, the stepwise linear multivariate regression revealed that decision-making was significantly predicted (p<0.001) by lithium dose, level of education and no family history of bipolar disorder (all p≤0.01). Because medication was not randomized, it was not possible to discriminate the effect of different medications. Lithium medication might be associated with better decision-making in remitted bipolar patients. A randomized trial is required to test for the hypothesis that lithium, but not other mood stabilizers, may specifically improve decision-making abilities in bipolar disorder.

Abstract
BACKGROUND ADHD involves impairing core symptoms of inattention and hyperactivity/impulsivity in children (childhood ADHD = CH) that may persist in adulthood (adult ADHD = AD). Conflicting findings have been found regarding AD prevalences among adult smokers, and it is unclear whether AD is associated with a more severe smoking behavior in adulthood. OBJECTIVE The aim of this article is (a) to determine CH and AD prevalences in a nonselected sample of adult smokers, (b) to describe the characteristics of smokers with ADHD symptoms versus those without, and (c) to determine whether CH and/or AD symptoms are risk factors for more severe smoking in adulthood. METHOD Three hundred and seventy-three participants aged 18 years and over were prospectively recruited in a smoking-cessation unit. Participants were classified as "no ADHD symptoms," "CH symptoms," or "AD symptoms" according to their baseline score on the Wender Utah Rating Scale (WURS) alone (for CH symptoms) and WURS combined to the Adult Self Report Scale (ASRS) for AD symptoms. Other clinical variables were reported at first consultation. RESULTS (a) CH symptoms were reported in 15.3% (57/373) of the total sample, 42.1% (24/57) of whom also had persistent ADHD symptoms in adulthood (prevalence of AD was 24/373 = 6.4%). (b) In comparison with participants without ADHD symptoms, smokers with ADHD symptoms consume significantly more tobacco, but ADHD symptoms were no longer significantly associated with the daily number of smoked cigarettes after adjustment for sociodemographic variables. No significant association was found between the two groups and age at the first cigarette, age at onset daily smoking, and nicotine dependence. (c) Participants were categorized into three groups: Group 1 without ADHD symptoms lifetime (NH; n = 316), Group 2 with childhood history of ADHD symptoms (CH; n = 33), and Group 3 with Adult ADHD symptoms (AD; n = 24). The association with tobacco consumption (>20 cigarettes/day) was significant for CH only (p = .02). After adjustment for gender, age, professional status, and educational level, this association was not longer significant. CONCLUSION Childhood and adult ADHD symptoms are both highly prevalent among nonselected smokers but our study failed to show more severe smoking characteristics among these participants after adjustment with sociodemographic variables.

Abstract
INTRODUCTION Those suicide attempters that choose violent methods dramatically diminish the possibility of survival. Completed suicide using violent means, which is common among first-time suicide attempters, was recently found to be more likely among T allele carriers in the three most common ABCB1 SNPs, encoding for P-gp. Thus, this study examined, for the first time, whether these ABCB1 SNPs were associated with the use of violent means among survivors of a suicide attempt. MATERIAL AND METHODS Suicide attempters (n = 578, 87.4% women; of whom 16.6% committed a violent intent) were genotyped for exonic SNPs in the ABCB1 (C1236T, G2677T/A, C3435T). The relations of the three genotypes and of the TTT haplotype with the use of a violent suicide method were evaluated separately. The impact of confounds on these variables was controlled. RESULTS A higher frequency (p = 0.02) of suicide attempters using violent methods was found among those carrying the ABCB1 haplotype (1236TT-2677TT-3435TT). Since gender and number of previous suicide attempts were identified as confounds, the relation was tested in the subset of women who were first-time attempters or second- and more-time attempters. The ABCB1 haplotype increased the risk more than three times in those women attempting a violent suicide for the first time (OR = 3.6; CI95%: 1.08-12.09; p = 0.04). DISCUSSION The ABCB1 haplotype (1236TT-2677TT-3435TT) was related to the use of a violent suicide attempt method. Genotyping for these three ABCB1 SNPs may be helpful to detect people at risk of first suicide intents using violent methods.

Abstract
Early life adversity plays a critical role in the emergence of borderline personality disorder (BPD) and this could occur through epigenetic programming. In this perspective, we aimed to determine whether childhood maltreatment could durably modify epigenetic processes by the means of a whole-genome methylation scan of BPD subjects. Using the Illumina Infinium® HumanMethylation450 BeadChip, global methylation status of DNA extracted from peripheral blood leucocytes was correlated to the severity of childhood maltreatment in 96 BPD subjects suffering from a high level of child adversity and 93 subjects suffering from major depressive disorder (MDD) and reporting a low rate of child maltreatment. Several CpGs within or near the following genes (IL17RA, miR124-3, KCNQ2, EFNB1, OCA2, MFAP2, RPH3AL, WDR60, CST9L, EP400, A2ML1, NT5DC2, FAM163A and SPSB2) were found to be differently methylated, either in BPD compared with MDD or in relation to the severity of childhood maltreatment. A highly relevant biological result was observed for cg04927004 close to miR124-3 that was significantly associated with BPD and severity of childhood maltreatment. miR124-3 codes for a microRNA (miRNA) targeting several genes previously found to be associated with BPD such as NR3C1. Our results highlight the potentially important role played by miRNAs in the etiology of neuropsychiatric disorders such as BPD and the usefulness of using methylome-wide association studies to uncover such candidate genes. Moreover, they offer new understanding of the impact of maltreatments on biological processes leading to diseases and may ultimately result in the identification of relevant biomarkers.

Abstract
OBJECTIVE Despite various strategies to help smokers with depressive disorders to quit, the smoking relapse rate remains high. The purpose of this pilot study was to estimate the effects of adding an exercise and counseling intervention to standard smoking cessation treatment for smokers with depressive disorders. We hypothesized that the exercise and counseling intervention would lead to improved abstinence, reduced depressive symptoms, and increased physical activity. METHODS Seventy smokers with current depressive disorders were randomly assigned to standard smoking cessation treatment plus exercise and counseling (n = 35) or standard treatment plus a time-to-contact control intervention on health education (n = 35). Both programs involved 10 sessions over 8 weeks. The primary outcome was continuous abstinence since the quit date and was measured at week 8 (end of the intervention) and again at 12-, 24-, and 52-week follow-ups. RESULTS Nearly 60% of participants were female (n = 41), 38 (52.3%) were single, 37 (52.9%) had education beyond high school, and 32 (45.7%) met criteria for major depressive disorder or dysthymia. Participants in the two treatment conditions differed at baseline only in marital status (χ(2) = 4.28, df = 1, p =.04); and smoking abstinence self-efficacy, t(66) = -2.04, p =.04). The dropout rate did not differ significantly between groups and participants attended 82% and 75% of the intervention and control sessions, respectively. Intention-to-treat analysis showed that, at 12 weeks after the beginning of the intervention, continuous abstinence did not vary significantly between the intervention and control groups: 48.5% versus 28.5%, respectively, ORadj = 0.40, 95% CI [0.12-1.29], p =.12. There were no group differences in depressive symptoms, but the intervention group did outperform the control group on the 6-minute walking test (Mint = 624.84, SD = 8.17, vs. Mcon = 594.13, SD = 8.96, p =.015) and perceived physical control (Mint = 2.84, SD = 0.16, vs. Mcon = 2.27, SD = 0.18, p =.028). The sample was not large enough to ensure adequate statistical power. CONCLUSIONS This finding, while preliminary, suggests that an exercise and counseling intervention may yield better results than health education in improving smoking abstinence. This study is registered at www.clinincaltrials.gov under # NCT01401569.

Abstract
OBJECTIVE Posttraumatic Stress Disorder (PTSD) and childhood abuse are both consistently associated with a higher risk for suicide attempts. We hypothesize that among patients reporting childhood abuse, PTSD diagnoses are correlated with an increased severity of suicidal features. METHOD We investigated 726 adult patients who had attempted suicide. These participants were assessed on lifetime clinical diagnoses and childhood abuse. The association of PTSD and childhood abuse dimensions with age at first suicide attempt, number of suicide attempts, violent attempts, serious attempts and suicide intent was studied. An adjusted multinomial logistic regression was performed to ascertain if childhood abuse and PTSD increased the severity of the suicidal behavior when combined. RESULTS Several types of childhood abuse (emotional, physical and sexual abuse) when combined with a lifetime diagnosis of PTSD showed an increased risk for more suicide attempts, serious attempts, and a higher level of suicidal intent compared with the absence of any or both risk factors. CONCLUSION The combination of PTSD and childhood abuse should be investigated in clinical settings due to an augmented risk for more severe suicidal behavior.

Abstract
Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide attempts and suicide completion. We aim to quantify the additive effect of family history of suicidal behavior and different subtypes of childhood abuse on suicidal behavior. We examined a sample of 496 suicide attempters, comparing individuals with family history of suicidal behavior and personal history of childhood (physical or sexual) abuse, individuals with family history of suicidal behavior only, individuals with history of early traumatic experiences only, and individuals with none of these two risk factors with regards to suicidal features. An additive effect was found for the age at the first attempt in suicide attempters with both family history of suicidal behavior and either physical or sexual abuse. No significant interactions were found between family history of suicidal behavior and childhood trauma in relation to any characteristics of suicidal behavior. Subjects presenting family history of suicidal behavior and childhood abuse attempt suicide earlier in life than subjects with just one or none of them, particularly if they were sexually abused. Other suicidality indexes were only partially or not associated with this combination of risk factors. A careful assessment of patients with both family history of suicidal behavior and childhood abuse could help to prevent future suicide attempts, particularly in young people.

Abstract
As part of a process to improve the quality of care, the French Society for Biological Psychiatry and Neuropsychopharmacology developed in 2010 formal consensus guidelines for the treatment of bipolar disorder. The evolution of therapeutic options available in France for the treatment of bipolar disorder has justified the update of this guideline. The purpose of this work was to provide an updated and ergonomic document to promote its use by clinicians. This update focuses on two of the six thematic previously published (acute treatment and long-term treatment). Aspects of the treatment of bipolar patients sparking debate and questions of clinicians (use of antidepressant, place of the bitherapy, interest of long-acting antipsychotics…) were also covered. Finally, we proposed graded recommendations taking into account specifically the risk-benefit balance of each molecule.

Abstract
Les troubles addictifs sont des troubles complexes où les traitements actuellement efficaces restent peu nombreux. Dans ce contexte, la tDCS de part son action neuromodulatrice, sa simplicité d’utilisation et sa faible innocuité pourrait être une option valable à la fois pour mieux comprendre la physiopathologie de ces troubles que comme traitement potentiel. Les comportements addictifs sont marqués par un ensemble de symptômes cognitifs, comportementaux et physiologiques faisant qu’un individu continue à consommer en dépit des conséquences négatives auquel il s’expose. Parmi ces caractéristiques, le craving est particulièrement impliqué dans le maintien des consommations. La neurobiologie du craving implique les régions préfrontales. Cela en fait une cible de choix pour la tDCS. Des études tDCS versus une stimulation placEbo ciblant le cortex préfrontal ont montré une diminution du craving. Ces résultats ont été retrouvé dans une série d’addiction allant du tabac à la methamphetamine en passant par l’alcool et la nourriture. Dans certaines études, cette diminution du craving était associée cliniquement à une diminution des consommations de nourriture ou de cigarettes.Une autre cible d’action potentielle pourrait être neurocognitive. Les addictions sont marquées par des altérations de la prise de décision, une hypersensibilité à la récompense et une impulsivité importante. Des études très préliminaires chez des sujet dépendants au tabac et au cannabis suggèrent qu’un programme de tDCS ciblant le cortex préfrontal dorsolatéral améliore ces fonctions neuropsychologiques et ainsi indirectement le pronostic de l’addiction. Les données actuelles ne permettent cependant pas de préciser si il existe un maintien à long terme des effets observés. L’intérêt clinique et les paramètres optimaux d’utilisation doivent également être mieux définis. Néanmoins ces premières données suggèrent que la tDCS pourrait permettre le développement de nouvelles approches thérapeutiques dans des troubles où les prises en charge actuelles sont perfectibles.

Abstract
BACKGROUND The mechanisms by which childhood abuse and family history of suicidal behavior (FHS) lead to an increased risk of suicidal behavior are still unknown. Impulsive aggression may play an intermediate role. We investigated whether greater scores for aggression and impulsivity might be associated with the effects of FHS and/or childhood abuse on the severity of suicidal behavior. METHOD We examined the scores of three scales measuring impulsive aggression in a sample of 696 suicide attempters. We compared the highest and lowest scores with regard to reports of childhood abuse and FHS using adjusted multinomial regression models. Genetic polymorphisms of the serotonergic system known to be associated with impulsive aggression were also analyzed. RESULTS Patients with high impulsive aggressive scores showed significant differences in sociodemographic, clinical and suicidal features compared with patients with low impulsive aggressive scores. Adjusted results showed that combinations of some types of childhood abuse and FHS, particularly emotional abuse and emotional neglect, are associated with high impulsivity and hostility scores. The SS genotype of the serotonin transporter gene (5-HTTLPR) was associated with high levels of impulsivity when the subjects reported emotional abuse [odds ratio (OR) 5.55, 95% confidence interval (CI) 1.75-17.5] or physical abuse (OR 5.03, 95% CI 1.50-16.9) in their childhood. CONCLUSIONS Our results support the role of impulsive aggression as one of the links that may connect childhood abuse and FHS with severity of suicidal behavior.

Abstract
Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3). Individual association analyses were conducted in each stratum and meta-analyzed across all 15 discovery data sets. Seventy-six (72 independent) single nucleotide polymorphisms were taken forward for in silico (two data sets) or de novo (13 data sets) replication genotyping in 2677 independent AN cases and 8629 European ancestry controls along with 458 AN cases and 421 controls from Japan. The final global meta-analysis across discovery and replication data sets comprised 5551 AN cases and 21 080 controls. AN subtype analyses (1606 AN restricting; 1445 AN binge-purge) were performed. No findings reached genome-wide significance. Two intronic variants were suggestively associated: rs9839776 (P=3.01 × 10(-7)) in SOX2OT and rs17030795 (P=5.84 × 10(-6)) in PPP3CA. Two additional signals were specific to Europeans: rs1523921 (P=5.76 × 10(-)(6)) between CUL3 and FAM124B and rs1886797 (P=8.05 × 10(-)(6)) near SPATA13. Comparing discovery with replication results, 76% of the effects were in the same direction, an observation highly unlikely to be due to chance (P=4 × 10(-6)), strongly suggesting that true findings exist but our sample, the largest yet reported, was underpowered for their detection. The accrual of large genotyped AN case-control samples should be an immediate priority for the field.

Peñas-Lledó E, Guillaume S, Naranjo MEG, Delgado A, Jaussent I, Blasco-Fontecilla H, Courtet P, LLerena A. A combined high CYP2D6-CYP2C19 metabolic capacity is associated with the severity of suicide attempt as measured by objective circumstances. THE PHARMACOGENOMICS JOURNAL 2014; 15:172-6. [PMID: 25113522 DOI: 10.1038/tpj.2014.42] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2014] [Revised: 06/10/2014] [Accepted: 06/18/2014] [Indexed: 12/18/2022]
Abstract
This study examined, for the first time, whether a high CYP2D6-CYP2C19 metabolic capacity combination increases the likelihood of suicidal intent severity in a large study cohort. Survivors of a suicide attempt (n=587; 86.8% women) were genotyped for CYP2C19 (*2, *17) and CYP2D6 (*3, *4, *4xN, *5, *6, *10, wtxN) genetic variation and evaluated with the Beck Suicide Intent Scale (SIS). Patients with a high CYP2D6-CYP2C19 metabolic capacity showed an increased risk for a severe suicide attempt (P<0.01) as measured by the SIS-objective circumstance subscale (odds ratio (OR)=1.37; 95% confidence interval (CI)=1.05-1.78; P=0.02) after adjusting for confounders (gender, age, level of studies, marital status, mental disorders, tobacco use, family history of suicide, personal history of attempts and violence of the attempt). Importantly, the risk was greater in those without a family history of suicide (OR=1.82; CI=1.19-2.77; P=0.002). Further research is warranted to evaluate whether the observed relationship is mediated by the role of CYP2D6 and CYP2C19 involvement in the endogenous physiology or drug metabolism or both.

Abstract
OBJECTIVE The characterization of major repeaters (individuals with ≥ 5 lifetime suicide attempts) is a neglected area of research. Our aim was to establish whether or not major repeaters are a distinctive suicidal phenotype, taking into account a wide range of potential competing risks including sociodemographic characteristics, personal and familial history, psychiatric diagnoses, and personality traits. METHOD This cross-sectional study included 372 suicide attempters admitted to a specialized unit for suicide attempters in Montpellier University Hospital, Montpellier, France, between October 12, 2000, and June 10, 2010. Logistic regression models controlling for potential confounders were used. RESULTS When compared with subjects who attempted suicide < 5 times, major repeaters were more likely to be female (odds ratio [OR] = 5.54; 95% CI, 1.41-21.81), to have a lower educational level (OR = 5.1; 95% CI, 1.55-17.2), to have lifetime diagnoses of anorexia nervosa (OR = 3.45; 95% CI, 1.10-10.84) and substance dependence (OR = 5.00; 95% CI, 1.37-18.27), and to have lower levels of anger expressed outward (OR = 0.17; 95% CI, 0.06-0.47) and higher levels of trait anger (OR = 2.82; 95% CI, 1.18-6.75). Major repeaters had significantly higher suicide risk (lethality) scores (OR = 2.14; 95% CI, 1.08-4.23). CONCLUSION Major repeaters are a distinctive suicidal phenotype characterized by a distinctive sociodemographic (ie, female gender, low education) and clinical profile (ie, trait anger, substance dependence, anorexia nervosa). If our results are replicated, specific preventive plans should be tailored to major repeaters.

Abstract
OBJECTIVES The aim of this study was to investigate whether the quadrivalent human papillomavirus (HPV) vaccine Gardasil is associated with a change in the risk of autoimmune disorders (ADs) in young female subjects. DESIGN Systematic case-control study of incident ADs associated with quadrivalent HPV vaccination in young women across France. PARTICIPANTS AND SETTING A total of 113 specialised centres recruited (from December 2007 to April 2011) females aged 14-26 years with incident cases of six types of ADs: idiopathic thrombocytopenic purpura (ITP), central demyelination/multiple sclerosis (MS), Guillain-Barré syndrome, connective tissue disorders (systemic lupus erythematosus, rheumatoid arthritis/juvenile arthritis), type 1 diabetes mellitus and autoimmune thyroiditis. Control subjects matched to cases were recruited from general practice. ANALYSIS Multivariate conditional logistic regression analysis; factors included age, geographical origin, smoking, alcohol consumption, use of oral contraceptive(s) or vaccine(s) other than Gardasil received within 24 months before the index date and personal/family history of ADs. RESULTS Overall, 211 definite cases of ADs were matched to 875 controls. The adjusted odds ratio (OR) for any quadrivalent HPV vaccine use was 0.9 [95% confidence interval (CI) 0.5-1.5]. The individual ORs were 1.0 (95% CI 0.4-2.6) for ITP, 0.3 (95% CI 0.1-0.9) for MS, 0.8 (95% CI 0.3-2.4) for connective disorders and 1.2 (95% CI 0.4-3.6) for type 1 diabetes. No exposure to HPV vaccine was observed in cases with either Guillain-Barré syndrome or thyroiditis. CONCLUSIONS No evidence of an increase in the risk of the studied ADs was observable following vaccination with Gardasil within the time periods studied. There was insufficient statistical power to allow conclusions to be drawn regarding individual ADs.

Abstract
OBJECTIVE This study examined the underlying processes of decision-making impairments in individuals with anorexia nervosa (AN) and bulimia nervosa (BN). We deconstructed their performance on the widely used decision task, the Iowa Gambling Task (IGT) into cognitive, motivational, and response processes using cognitive modeling analysis. We hypothesized that IGT performance would be characterized by impaired memory functions and heightened punishment sensitivity in AN, and by elevated sensitivity to reward as opposed to punishment in BN. METHOD We analyzed trial-by-trial data of IGT obtained from 224 individuals: 94 individuals with AN, 63 with BN, and 67 healthy comparison individuals (HC). The prospect valence learning model was used to assess cognitive, motivational, and response processes underlying IGT performance. RESULTS Individuals with AN showed marginally impaired IGT performance compared to HC. Their performance was characterized by impairments in memory functions. Individuals with BN showed significantly impaired IGT performance compared to HC. They showed greater relative sensitivity to gains as opposed to losses than HC. Memory functions in AN were positively correlated with body mass index. DISCUSSION This study identified differential impairments underlying IGT performance in AN and BN. Findings suggest that impaired decision making in AN might involve impaired memory functions. Impaired decision making in BN might involve altered reward and punishment sensitivity.

Abstract
BACKGROUND Long-acting injectable (LAI) formulations are not widely used in routine practice even though they offer advantages in terms of relapse prevention. As part of a process to improve the quality of care, the French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) elaborated guidelines for the use and management of antipsychotic depots in clinical practice. METHODS Based on a literature review, a written survey was prepared that asked about 539 options in 32 specific clinical situations concerning 3 fields: target-population, prescription and use, and specific populations. We contacted 53 national experts, 42 of whom (79%) completed the survey. The options were scored using a 9-point scale derived from the Rand Corporation and the University of California in the USA. According to the answers, a categorical rank (first-line/preferred choice, second-line/alternate choice, third-line/usually inappropriate) was assigned to each option. The first-line option was defined as a strategy rated as 7-9 (extremely appropriate) by at least 50% of the experts. The following results summarize the key recommendations from the guidelines after data analysis and interpretation of the results of the survey by the scientific committee. RESULTS LAI antipsychotics are indicated in patients with schizophrenia, schizoaffective disorder, delusional disorder and bipolar disorder. LAI second-generation antipsychotics are recommended as maintenance treatment after the first episode of schizophrenia. LAI first-generation antipsychotics are not recommended in the early course of schizophrenia and are not usually appropriate in bipolar disorder. LAI antipsychotics have long been viewed as a treatment that should only be used for a small subgroup of patients with non-compliance, frequent relapses or who pose a risk to others. The panel considers that LAI antipsychotics should be considered and systematically proposed to any patients for whom maintenance antipsychotic treatment is indicated. Recommendations for medication management when switching oral antipsychotics to LAI antipsychotics are proposed. Recommendations are also given for the use of LAI in specific populations. CONCLUSION In an evidence-based clinical approach, psychiatrists, through shared decision-making, should be systematically offering to most patients that require long-term antipsychotic treatment an LAI antipsychotic as a first-line treatment.

Abstract
Les techniques de neuromodulation sont de plus en plus utilisées en psychiatrie. Dans le contexte des troubles des conduites alimentaires (TCA) où peu de prises en charge efficaces sont disponibles, plusieurs de ces techniques pourraient avoir un intérêt pour mieux appréhender la physiopathologie et/ou comme thérapie innovante. Trois techniques émergent. Deux sont des techniques de neuromodulation non invasives : la repetitive Transcranial Magnetic Stimulation (rTMS) et la transcranial Direct-Current Stimulation (tDCS) et une nécessite une intervention chirurgicale : la stimulation cérébrale profonde. Dans la boulimie, plusieurs études versus placebo utilisant la rTMS ont montré une diminution des pulsions alimentaires sur du court terme. Nos résultats préliminaires dans une étude multicentrique suggèrent une diminution du nombre de crises dans les 15 jours post-rTMS. La rTMS dans cette population est bien tolérée. Une série d’études pilote suggère également que la tDCS diminue les pulsions et les prises alimentaires et améliore des fonctions cognitives perturbées dans les TCA. Dans l’anorexie, la tolérance de la rTMS a été montrée comme bonne, même chez des patientes à poids très bas. Plusieurs études sont actuellement en cours pour évaluer l’effet sur des fonctions-clés de l’anorexie comme la perception corporelle ou la conscience intéroceptive avec pour objectif essentiel de mieux cerner la physiopathologie. Mais la technique de neuromodulation qui offre le plus d’espoir est la stimulation cérébrale profonde. Deux études pilotes récentes chez des patientes anorexiques très sévères suggèrent non seulement une bonne tolérance mais aussi une amélioration très nette de la symptomatologie alimentaire dans les mois ayant suivi l’intervention. Néanmoins, ces études restent à répliquer et les meilleurs sites et protocoles de stimulation restent à définir. Ainsi, ces techniques suscitent beaucoup d’espoir dans des pathologies résistantes mais leurs efficacités potentielles et utilisation clinique restent encore à définir.

Abstract
BACKGROUND Pre- and perinatal insults increase suicide risk. The main objective of the present study is to investigate if prematurity interacts in an additive fashion with postnatal risk factors of suicidal behavior. METHOD Sample and procedure: 857 adult suicide attempters consecutively hospitalized for a suicide attempt were included. Studied characteristics of suicide attempts included use of a violent mean, age at first suicide attempt, and number of suicide attempts. Risk factors of suicidal behavior included indexes of pre- and perinatal adversity, childhood maltreatment as measured with the Childhood Trauma Questionnaire, personality traits as measured with the Tridimensional Personality Questionnaire, and family history of suicidal behavior. STATISTICAL ANALYSES Comparisons between the different patterns of suicide attempts characteristics were made using logistic regression with crude and adjusted odds ratios and 95% confidence intervals. RESULTS The risk of violent suicide attempts increased significantly in patients born prematurely (OR [95%] = 2.38[1.12-5.08]). There were additive effects for very preterm birth and 1) emotional abuse (OR [95% CI] = 4.52 [1.75-11.60]), 2) novelty seeking (OR [95% CI] = 8.92[3.09-25.7]), and 3) harm avoidance (OR [95% CI] = 5.81 [2.43-13.90]) on the age at first suicide attempt, after adjustment for potential confounders. CONCLUSIONS Very preterm birth appears to be the first step in a cascade of stressors across lifetime, which affects the risk and the severity of suicidal behavior. Furthermore, very preterm birth, childhood maltreatment and personality traits have additive effects that influence the age at onset of suicide attempt. Our findings may have potential consequences for preventive policies.

Abstract
OBJECTIVE The association between major depressive symptoms and smoking has been extensively documented. However, previous studies report conflicting findings about the impact of depression on lapse of smoking cessation. We hypothesize that smokers with self-reported major depressive symptoms at baseline are at higher risk of a lapse. METHODS One thousand and twenty participants aged, 18 years and over, were recruited in a smoking-cessation unit. All participants were assessed for their smoking status six times during one year of follow-up. Participants were classified as "euthymic", presenting "minor depressive symptomatology" or "major depressive symptomatology" according to their baseline score on the Hospitalization Anxiety and Depression Scale. RESULTS Using Cox's proportional hazard regression modeling, adjusted for potential confounding factors (nicotine dependence, number of cigarettes/day, previous cessation attempt, alcohol misuse, socio-demographic variables), it was shown that lapse is associated with major depressive symptoms (Hazard Ratio: HR=1.23 [1.02;1.47]; p=0.03). CONCLUSION Our results suggest the importance for clinicians to deal with depression and to discriminate minor from major depressive symptoms at preliminary smoking cessation consultations.

Abstract
OBJECTIVE Numerous guidelines for bipolar disorder have been published. The aim of this article is to underline the main differences between consensus-based guidelines (CBG) and evidence-based guidelines (EBG) currently available for the management of bipolar disorder. METHODS A literature search for guidelines published since 2006 was performed. A qualitative analysis was then conducted to compare the methodologies and the guidelines contents. RESULTS Comparison between CBG and EBG found more similarities than differences. However, discordances were found in the first-line choice of treatment (monotherapy or combination, use of lamotrigine or lithium in bipolar depression), time to reassessment and duration of maintenance treatment, introduction as from the acute phase a regimen compatible with long-term use and pharmacotherapy during pregnancy. CONCLUSIONS The choice of policy, whatever the methodology used, is up to the authors and can, therefore, depend on their interpretation of the available scientific evidence. Combining both methodologies (CBG and EBG) enables us to meet the complete definition of evidence-based medicine.

Abstract
INTRODUCTION Smoking is significantly more common among persons with major depressive disorders (MDDs). Furthermore, smokers with MDD report more difficulties when they quit smoking (greater withdrawal symptoms, higher probability of relapse). The aim of this narrative review is to describe research on exercise and depression and exercise and smoking cessation. METHODS We have critically reviewed various smoking cessation intervention programs for depressive smokers examining (a) the protective effect of exercise against relapse for smokers with MDD and (b) the benefits of exercise for treating withdrawal symptoms. We have also reviewed the current literature investigating the mechanisms between exercise-depression and exercise-smoking. RESULTS This review suggests that exercise may reduce depressive symptoms following cessation and provide a useful strategy for managing withdrawal symptoms in smokers with MDD. Various psychological, biological, and genetic hypotheses have been tested (e.g., distraction hypothesis, expectations hypothesis, cortisol hypothesis) and few have obtained significant results. CONCLUSIONS It might be beneficial for health professionals to recommend physical activity and promote supervised exercise sessions for smokers with MDD during smoking cessation. Future research needs to examine relationships between exercise, smoking, and depression with transdisciplinary and ecological momentary assessment.

Abstract
Decision-making impairment is found in several neuropsychiatric disorders, including suicidal behavior, and has been shown to be modulated by genes. On the other hand, early trauma have/has been associated with poor mental health outcome in adulthood, in interaction with genetic factors, possibly through sustained alterations in the hypothalamic-pituitary-adrenal axis (HPA axis). Here, we aimed to investigate the effect of childhood trauma and its interaction with HPA-axis related genes on decision-making abilities in adulthood among a sample of suicide attempters. The Iowa Gambling Task (IGT) was used to assess decision-making in 218 patients with a history of suicide attempt. Participant fulfilled the Childhood Trauma Questionnaire to report traumatic childhood experiences. Patients were genotyped for single-nucleotide polymorphisms within CRHR1 and CRHR2 genes. Patients with a history of sexual abuse had significantly lower IGT scores than non-sexually abused individuals. Polymorphisms within CRHR1 and CRHR2 genes interacted with both childhood sexual abuse and emotional neglect to influence IGT performance. In conclusion, childhood sexual abuse and emotional neglect may have long-term effects on decision-making through an interaction with key HPA axis genes. Even if these results need to be replicated in other sample, impaired decision-making may thus be the dimension through which child maltreatment, in interaction with HPA axis related genes, may have a sustained negative impact on adult mental health.
