Abstract in English:

Objective To investigate factors associated with violent behavior in a large nationally representative sample of Brazilian adolescents. Methods The data were derived from the 2015 National Adolescent School-based Health Survey (Pesquisa Nacional de Saúde do Escolar [PeNSE]). The independent variables of interest included feelings of safety while on the way to and at school. The outcome was violent behavior, including bullying. Logistic regression models were developed to examine the relationship between violent behavior and each independent and control variable. Results In the adjusted regression model, male sex (aOR: 1.75; 95%CI 1.65-1.86), being assaulted by a family member (aOR: 1.74; 95%CI 1.59-1.90), and being assaulted in the past year (aOR: 1.70; 95%CI 1.57-1.85) all increased the chance of violent behavior. Feeling safe on the way to school (aOR: 0.82; 95%CI 0.74-0.92) and at school (aOR: 0.82; 95%CI 0.73-0.92) reduced the chance of violent behavior. Conclusion This study extends the body of literature on violent behavior among adolescents, demonstrating a correlation between school, domestic, family, or community violence and violent behavior. Our research supports the idea that adolescents who experience violence act violently with greater frequency. This finding has significant implications for pediatricians, child psychiatrists and psychologists, other health care professionals, school professionals, and other professionals involved in adolescent health. School professionals must be prepared to identify adolescents with violent behavior due to its potential consequences for their mental and physical health.

Objective: Bipolar disorder is a heritable chronic mental disorder that causes psychosocial impairment through depressive/manic episodes. Familial transmission of bipolar disorder does not follow simple Mendelian patterns of inheritance. The aim of this study was to describe a large family with 12 members affected by bipolar disorder. Whole-exome sequencing was performed for eight members, three of whom were diagnosed with bipolar disorder, and another reported as “borderline.” Methods: Whole-exome sequencing data allowed us to select variants that the affected members had in common, including and excluding the “borderline” individual with moderate anxiety and obsessive-compulsive traits. Results: The results favored designating certain genes as predispositional to bipolar disorder: a heterozygous missense variant in CLN6 resulted in a “borderline” phenotype that, if combined with a heterozygous missense variant in ZNF92, is responsible for the more severe bipolar disorder phenotype. Both rare missense changes are predicted to disrupt protein function. Conclusions: Loss of both alleles in CLN6 causes neuronal ceroid lipofuscinosis, a severe progressive childhood neurological disorder. Our results indicate that heterozygous CLN6 carriers, previously reported as healthy, may be susceptible to bipolar disorder later in life if associated with additional variants in ZNF92.

Objectives: To examine the composition of self-regulation in pediatric bipolar disorder (PBD) through the relationship between executive functions, emotion processing, and family environmental factors. Methods: 58 participants (36 with PBD and 22 controls), ages 12-17, were assessed using the Barratt Impulsiveness Scale (BIS), Conners’ Continuous Performance Test (CPT-II), Wisconsin Cards Sorting Test (WCST), Computerized Neurocognitive Battery Emotion Recognition Test-Facial Emotion Recognition Test (PENNCNB ER-40), and Expressed Emotion Adjective Checklist Questionnaire (EEAC). Results: Adolescents with PBD displayed significant deficits in all three spheres when compared to the control group. Emotion processing correlated negatively with inhibition and attention, and correlated positively with mental flexibility/working memory. Family environmental factors correlated negatively with mental flexibility/working memory and emotion processing, and positively with attention and inhibition. These correlations indicate that better inhibitory control, attention, and mental flexibility/working memory are associated with greater emotion processing and a fitter family environment. Conclusion: This study is the first to investigate all of the components of self-regulation deficits simultaneously in patients with PBD. Results suggest that self-regulation is essential for a comprehensive perspective of PBD and should be assessed in an integrative and multifaceted way. Understanding that self-regulation is impacted by the abovementioned factors should influence treatment and improve the functional impairments of daily life observed in this population.

Objectives: Although an association has been found recently between obsessive-compulsive disorder and an increased risk of suicide, the prevalence of both suicidal ideation and attempts vary considerably and are generally assessed categorically. Our aims were to evaluate the prevalence of suicidal ideation and behaviors using a dimensional approach. Methods: The sample included 129 patients with obsessive-compulsive disorder. Suicidality was assessed by administering the Columbia-Suicide Severity Rating Scale. Logistic and linear regressions were used to examine predictors of suicidal ideation, severe suicidal ideation, and suicidal behavior. Results: The lifetime prevalence of suicidal ideation and behaviors were 64.3% and 16.3%, respectively. Lifetime suicidal ideation was associated with the number of stressful life events, duration of illness, Hamilton Rating Scale for Depression scores, and family history of mood disorders. A family history of obsessive-compulsive disorder was associated with a lower probability of lifetime suicidal ideation. Severe suicidal ideation was related to greater severity of the most stressful life event, Hamilton Rating Scale for Depression scores, and longer duration of untreated illness. The probability of lifetime suicidal behavior was related to Hamilton Rating Scale for Anxiety scores, symmetry obsessions, and washing and checking compulsions. The probability of lifetime non-suicidal self-injurious behaviors was related to Hamilton Rating Scale for Anxiety scores. Conclusions: Recognizing predictors of suicidal ideation/behavior is crucial to identifying patients at greater risk.

Objective: Childhood sexual abuse is associated with compulsive sexual behavior, depression, and anxiety in men. Furthermore, both depression and anxiety have been linked to compulsive sexual behaviors. However, whether anxiety and depression mediate the relationship between childhood sexual abuse and compulsive sexual behaviors has yet to be tested. We investigated whether symptoms of depression and anxiety mediate the relationship between childhood sexual abuse and compulsive sexual behaviors in 222 men seeking treatment for such behaviors. Methods: Participants completed the Sexual Compulsivity Scale, Childhood Trauma Questionnaire, Beck Depression Inventory, and Beck Anxiety Inventory. A cross-sectional parallel mediation analysis was conducted. Results: The prevalence of childhood sexual abuse in our sample was 57%. Significant correlations were found between childhood sexual abuse and compulsive sexual behaviors, depression, and anxiety. The results of the mediation analyses suggested that depression (B = 0.07, standard error [SE] = 0.03, 95%CI 0.02 to 0.15), but not anxiety (B = 0.02, SE = 0.02, 95%CI -0.2 to 0.07), mediated the link between childhood sexual abuse and compulsive sexual behaviors. The pattern of our results remained the same when controlling for other types of childhood trauma. Conclusions: Depression, not anxiety, appears to mediate the relationship between childhood sexual abuse and compulsive sexual behaviors in men. Future research that tests our mediation analyses using a prospective longitudinal study would be highly informative.

Objectives: To re-evaluate a sample of older adults enrolled in a randomized controlled trial of lithium for amnestic mild cognitive impairment (MCI) after 11 to 15 years, re-assessing their current (or last available) global cognitive and functional state. Methods: We recalled all former participants of the Lithium-MCI trial conducted by our group between 2009 and 2012 to perform a single-blinded, cross-sectional evaluation of their global clinical state to compare the long-term outcome of those who received lithium vs. those who received placebo. Results: Of the original sample (n=61), we were able to reach 36 participants (59% of retention), of whom 22 had previously received lithium (61% of the recall sample) and 14 (39%) had received placebo. Since 30.5% of the recalled sample was deceased, psychometric data were collected only for 69.5% of the participants. We found statistically significant differences in current mean Mini Mental State Examination score according to previous treatment group (25.5 [SD, 5.3] vs. 18.3 [SD, 10.9], p = 0.04). The lithium group also had better performance in the phonemic Verbal Fluency Test than the control group (34.4 [SD, 14.4] vs. 11.6 [SD, 10.10], p < 0.001). Differences in these measures also had large effect sizes, as shown by Cohen’s d values of 0.92 and 1.78, respectively. Conclusion: This data set suggests that older adults with amnestic MCI who had been treated with lithium during a previous randomized controlled trial had a better long-term global cognitive outcome than those from a matched sample who did not receive the intervention.

Objective: To test the efficacy of smartphone-assisted online brief cognitive behavioral therapy (b-CBT) to treat maternal depression compared to online brief CBT plus an active control app. Methods: A randomized controlled trial was conducted. Assessments were performed at baseline (T0), midpoint (T1, week 4-5), post-treatment (T2, week 8), and follow-up (T3, 2-month postnatal follow-up) by blinded interviewers. The primary outcome was depression measured by the Edinburgh Postnatal Depression Scale (EPDS) at T2. We also assessed anxiety, stress, sleep quality, well-being, physical activity, treatment response, and offspring child behavior problems. Results: Eighty-one participants were randomized to the intervention (n=37) or active control (n=44) groups. Seventy-one participants completed the post-treatment assessment or reported primary outcome data. No differences were found between the intervention and active control groups regarding maternal depression or other mental health outcomes. Overall, we found large within-group effect sizes, with 80% of the total sample responding to treatment. Conclusions: Our data showed no difference between the groups, suggesting that adding apps to psychotherapy treatment may not enhance treatment effects on prenatal depression. A within-groups analysis showed that most participants with depression responded to treatment; however, future studies are needed to confirm whether this effect is related to factors other than the intervention.

Abstract in English:

Crisis hotlines are direct communication systems, usually telephone-based, set up to prevent suicide. However, few studies have evaluated their effectiveness. The present study aims to perform a systematic review, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, of the effectiveness of interventions through direct communication systems to reduce the number of suicides or suicide attempts. We searched the MEDLINE, Cochrane, SciELO, and ClinicaTrials.gov databases, and used the 2011 Oxford Centre for Evidence-Based Medicine Levels of Evidence classification. The literature search yielded 267 studies, of which 35 fulfilled the selection criteria. Although significant heterogeneity was found among studies, there is evidence that direct telephone interventions are effective when included in broader preventive protocols and provided by trained staff. Despite the limitations, which included heterogeneity of samples, designs, and outcome measures, we were able to design a protocol for the use of remote services to prevent suicide and suicide attempts. A hotline or similar system could be an effective intervention for broader suicide prevention programs. However, further research is necessary to specify which protocol components are key to enhance effectiveness. Systematic review registry number: PROSPERO CRD42020206517

Abstract in English:

Objectives: To synthesize and reinterpret findings from primary qualitative studies on the emotional experience of health care professionals working with mental health and mental health professionals providing care for people with suicidal behavior. Methods: We conducted a systematic review of the literature with the SPIDER structured search strategy in six databases (PubMed, Web of Science, Scopus, PsycINFO, CINAHL, and LILACS). A meta-synthesis was performed with data from qualitative studies published between 2005 and 2021. Two independent reviewers screened and assessed the articles. They evaluated methodological quality of included articles, extracted data, and performed the thematic synthesis. Results: Of 852 articles, 21 met the inclusion/exclusion criteria and were synthesized. The meta-synthesis revealed three descriptive themes: coping with adverse experiences; coming across fortunate experiences; professional-personal implications. Based on these descriptive themes, we elaborated the analytical theme: bittersweet experiences of personal and professional transformation. Conclusions: Mental health professionals working with people manifesting suicidal behaviors must cope with complex emotional experiences that involve controversial and ambivalent feelings. Such feelings have repercussions that may transform personal and professional life. The present results are useful for the development and implementation of interventions that promote better overall mental health outcomes for healthcare providers.

Abstract in English:

Objective: To provide a review of journal articles discussing clinical cases or vignettes of psychoanalysis or psychoanalytic psychotherapy of patients affected by bipolar disorder. Methods: A thorough search of journal articles was performed in five databases to identify studies published from 1990-2021. Results: Twenty-four articles were included in this review, comprising a total of 29 case reports. The most common theoretical approach adopted by the authors was “object relations.” Two main sets of clinical-theoretical considerations and recommendations emerge: the applicability of analytic treatment to patients with bipolar disorder – taking into account their analyzability and practical arrangements for conducting therapy – and theoretical speculations on the nature and development of the illness, as well as on the conceptualization of its different phases. Conclusion: Our findings reveal that there is some psychoanalytic literature providing insight into the psychological dynamics and treatment of patients with bipolar disorder. Elaboration of this literature may help improve our understanding and provide more accurate and comprehensive descriptions of the intrapsychic and interpersonal dynamics of these patients, yielding potentially valuable information for clinical and research purposes, particularly with regard to reducing interpersonal conflict, and increasing insight and engagement with lifestyle changes and other behaviors likely to promote health and stability.
