Suicide in a large population of former psychiatric inpatients

Aims:  The aim of this study was to identify predictors of completed suicide in a wide sample of psychiatric inpatients receiving retrospective and prospective DSM‐IV diagnoses.

Suicide risk in depression and bipolar disorder: Do impulsiveness-aggressiveness and pharmacotherapy predict suicidal intent?

The aims of the present study were to examine clinical, personality, and sociodemographic predictors of suicide risk in a sample of inpatients affected by major affective disorders. The participants were 74 inpatients affected by major depressive disorder or bipolar disorder-I. Patients completed a semi-structured interview, the Beck Hopelessness Scale, the Aggression Questionnaire, the Barratt Impulsiveness Scale, and the Hamilton scales for depression and anxiety. Over 52% of the patients were high suicide risks. Those at risk reported more severe depressive-anxious symptomatology, more impulsivity and more hostility. Impulsivity, the use of antidepressants, anxiety/somatization, and the use of mood stabilizers (a negative predictor) resulted in accurate predicting of suicide intent. Impulsivity and antidepressant use were the strongest predictors even after controlling for several sociodemographic and clinical variables.

Suicide after surgical treatment in patients with epilepsy: a meta-analytic investigation

Suicide is a major issue in surgically treated epileptic patients. A meta-analysis was performed comparing suicides in a sample of such patients and in the general population. The Index Medicus and the World Health Statistics Annual were searched to ascertain the suicide rates in the age groups indicated in the studies of epileptic patients for specific years and country. 11 studies were selected, comprising 2,425 patients, 24 of whom committed suicide. Data obtained for each study were processed together to calculate the mean number of suicides per 100,000 individuals with surgically treated epilepsy for each year. This meta-analysis shows that suicide in patients with epilepsy after surgical treatment is more frequent than in the general population. Results are discussed with particular attention to possible causative factors.

Stigmatization of schizophrenia as perceived by nurses, medical doctors, medical students and patients

Stigmatization of schizophrenia is widespread and its genetic explanation may potentially increase the stigma. The present study investigated whether seeing schizophrenia as a genetic or environmental disorder might influence perceived beliefs towards people with schizophrenia and whether social stigmatizing attitudes were differently perceived the 202 subjects who were recruited. Perceived social stigmatizing attitudes were compared among participants who read two vignettes depicting a person with schizophrenia. Then, the Standardized Stigmatization Questionnaire (SSQ) was administered. A genetic explanation of schizophrenia was more frequently associated with stigmatizing attitudes. Also, there were higher levels of perceived stigmatization in medical students and medical doctors than in other groups based on their social experience or background. However, the sample size was small and this was a non-experimental design; also the SSQ would benefit from more cross-validation. About half of the participants perceived stigmatizing social attitudes. Finally, considering schizophrenia as a genetic disorder influenced participants perception of other peoples beliefs about dangerousness and unpredictability and peoples desire for social distance.

Efficacy of Add-On Deep Transcranial Magnetic Stimulation in Comorbid Alcohol Dependence and Dysthymic Disorder: Three Case Reports

BACKGROUND Craving for alcohol is associated with abnormal activation in the dorsolateral prefrontal cortex. Deep transcranial magnetic stimulation (dTMS) has shown promise in the treatment of depression. There are few treatment options for treatment-resistant dysthymic disorder comorbid with alcohol use disorder. OBJECTIVE To investigate the possible anticraving efficacy of bilateral dorsolateral prefrontal cortex high-frequency dTMS in 3 patients with comorbid long-term DSM-IV-TR dysthymic disorder and alcohol use disorder. METHOD Three patients with alcohol use disorder with dysthymic disorder in their detoxification phase (abstaining for > 1 month) underwent twenty 20-minute sessions of 20 Hz dTMS over the dorsolateral prefrontal cortex over 28 days between 2011 and 2012. Alcohol craving was rated with the Obsessive Compulsive Drinking Scale and depressive symptoms with the Hamilton Depression Rating Scale. RESULTS All 3 patients responded unsatisfactorily to initial intravenous antidepressant and antianxiety combinations but responded after 10 dTMS sessions, improving on both anxiety-depressive symptoms and craving. This improvement enabled us to reduce antidepressant dosages after dTMS cycle completion. DISCUSSION High-frequency bilateral dorsolateral prefrontal cortex dTMS with left prevalence was found to produce significant anticraving effects in alcohol use disorder comorbid with dysthymic disorder. The potential of dTMS for reducing craving in patients with substance use disorder deserves to be further investigated.

Childhood traumatic experiences of patients with bipolar disorder type i and type II

BACKGROUND Childhood trauma is an important environmental stressor associated with bipolar disorders (BD). It is still not clear if it is differently distributed between BD I and BD II. Therefore, the aim of this research was to investigate the distribution patterns of childhood trauma in BD I and BD II. In this perspective, we also studied the relationship between childhood trauma and suicidality. METHODS We assessed 104 outpatients diagnosed with BD I (n=58) or BD II (n=46) according to DSM-IV-TR criteria and 103 healthy controls (HC) matched for age, sex and education level. History of childhood trauma was obtained using the Childhood Trauma Questionnaire (CTQ). RESULTS All patients with BD had had more severe traumatic childhood experiences than HC. Both BD I and BD II patients differed significantly from HC for trauma summary score and emotional abuse. BD I patients differed significantly from HC for sexual abuse, and BD II differed from HC for emotional neglect. BD I and BD II did not significantly differ for any type of trauma. Suicide attempts were linked to both emotional and sexual abuse in BD I and only to emotional abuse in BD II. Emotional abuse was an independent predictor of lifetime suicide attempts in BD patients. LIMITATIONS The reliability of the retrospective assessment of childhood trauma experiences with the CTQ during adulthood may be influenced by uncontrolled recall bias. CONCLUSIONS The assessment of childhood trauma, which has great clinical importance because of its strong link with suicidality, can unveil slight differences between BD subtypes and HC.

Add-on deep transcranial magnetic stimulation (dTMS) in patients with dysthymic disorder comorbid with alcohol use disorder: A comparison with standard treatment

Abstract Objectives. Dorsolateral prefrontal cortex (DLPFC) is dysfunctional in mood and substance use disorders. We predicted higher efficacy for add-on bilateral prefrontal high-frequency deep transcranial magnetic stimulation (dTMS), compared with standard drug treatment (SDT) in patients with dysthymic disorder (DD)/alcohol use disorder (AUD) comorbidity. Methods. We carried-out a 6-month open-label study involving 20 abstinent patients with DSM-IV-TR AUD comorbid with previously developed DD. Ten patients received SDT for AUD with add-on bilateral dTMS (dTMS-AO) over the DLPFC, while another 10 received SDT alone. We rated alcohol craving with the Obsessive Compulsive Drinking Scale (OCDS), depression with the Hamilton Depression Rating Scale (HDRS), clinical status with the Clinical Global Impressions scale (CGI), and global functioning with the Global Assessment of Functioning (GAF). Results. At the end of the 20-session dTMS period (or an equivalent period in the SDT group), craving scores and depressive symptoms in the dTMS-AO group dropped significantly more than in the SDT group (P < 0.001 and P < 0.02, respectively). Conclusions. High frequency bilateral DLPFC dTMS with left preference was well tolerated and found to be effective as add-on in AUD. The potential of dTMS for reducing craving in substance use disorder patients deserves to be further investigated.

Maintenance Deep Transcranial Magnetic Stimulation Sessions are Associated with Reduced Depressive Relapses in Patients with Unipolar or Bipolar Depression

Introduction: Deep transcranial magnetic stimulation (dTMS) is a new form of TMS allowing safe stimulation of deep brain regions. The objective of this preliminary study was to assess the role of dTMS maintenance sessions in protecting patients with bipolar disorder (BD) or recurrent major depressive disorder (MDD) from developing depressive or manic relapses in a 12-month follow-up period. Methods: Twenty-four drug-resistant patients with a current depressive episode and a diagnosis of MDD or BD have been enrolled in the study. All the participants underwent daily dTMS sessions for 4 weeks. One group (maintenance – M group) received additional maintenance dTMS sessions weekly or twice a week. Results: After the first dTMS cycle, a significant reduction of Hamilton Depression Rating Scale (HDRS) scores was observed in all participants. Subsequently, the HDRS mean scores did not significantly change over time in the M group, while it significantly increased in the non-M-group after 6 and 12 months. Discussion: This study confirms previous evidence of a positive therapeutic effect of dTMS on depressive symptoms and suggests that, after recovery from acute episodes, maintenance dTMS sessions may be helpful in maintaining euthymia in a 12-month follow-up period.

Temperament, Post-Partum Depression, Hopelessness, and Suicide Risk Among Women Soon After Delivering

The aim of the authors in this study was to assess the prevalence of postpartum depression and evaluate the association of affective temperaments with emotional disorders in a sample of 92 pregnant women consecutively admitted for delivery between March and December 2009. In the first few days postpartum, women completed the Suicidal History Self-rating Screening Scale, the Beck Hopelessness Scale, the Edinburgh Postnatal Depression Scale, the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego Autoquestionnaire, and the Gotland Male Depression Scale. Fifty percent of the women reported an Edinburgh Postnatal Depression Scale score of 9 or higher, and 23% a score of 13 or higher. Women with a dysphoric-dysregulated temperament had higher mean scores on the Beck Hopelessness Scale (p < 0.05), the Gotland Male Depression Scale (p < 0.001), the Edinburgh Postnatal Depression Scale (p < 0.001), and the Suicidal History Self-Rating Screening Scale (p < 0.01) than other women after adjusting for covariates. Multiple logistic regression analysis with the temperament groups as the dependent variable indicated that only the Gotland Male Depression Scale was significantly associated with temperament when controlling for the presence of other variables. Women with a dysphoric-dysregulated temperament were 1.23 times as likely to have higher depressive symptom scores. Future studies should evaluate the effectiveness of psychiatric screening programs in the postpartum period as well as factors associated with depression and suicidality during the same period.

Add-on high frequency deep transcranial magnetic stimulation (dTMS) to bilateral prefrontal cortex reduces cocaine craving in patients with cocaine use disorder

INTRODUCTION Cocaine dependence is a substantial public health problem. The aim of this study is to evaluate the effect of high frequency deep transcranial magnetic stimulation (dTMS) on craving in patients with cocaine use disorder (CUD). METHODS Seven men (mean age, 48.71 years; standard deviation [SD], 9.45; range 32-60 years) with CUD and no concurrent axis 1 or 2 disorder save nicotine abuse, underwent three sessions of alternate day 20Hz dTMS in 20 trains delivered to the dorsolateral prefrontal cortex (DLPFC) preferentially to the left hemisphere, for 12 sessions spread over one month, added to unchanged prior drug treatment. We used a visual analogue scale (VAS) to measure cocaine craving the week before, each week during, and one month after dTMS treatment. RESULTS DLPFC stimulation significantly reduced craving over time: within-subjects main effect of time of treatment (ANOVA, F[3,18]=46.154; p<0.001; η(2)=0.88). The reduction of craving from baseline was significant at two weeks (p<0.001), and four weeks (p<0.001) of treatment, and at the week eight, four weeks after treatment interruption (p=0.003), although the increase of craving was significant from week four and eight (p=0.014). CONCLUSION dTMS over left DLPFC reduced craving in CUD patients in a small sample that is to be considered preliminary. However, maintenance sessions would be needed to maintain the achieved results. Our findings highlight the potential of noninvasive neuromodulation as a therapeutic tool for cocaine addiction.
