Carla R. Zuquetto; Emérita S. Opaleye; Marianne R. Feijó; Tatiana C. Amato; Cleusa P. Ferri; Ana R. Noto
Abstract

OBJECTIVE: To estimate the association of parental drunkenness and parenting style with alcohol consumption among adolescents and the contributions of parental drunkenness and parenting style to the prevalence of binge drinking among adolescents.
METHOD: Cross-sectional survey of a representative sample of secondary students aged 13 to 18 from 27 Brazilian state capitals (n=17,028). Private and public schools were included. A self-report questionnaire collected data on adolescents' alcohol drinking behavior, parenting styles, and parenting and peer models of drunkenness.
RESULTS: Non-authoritative parenting style and parental drunkenness are associated with binge drinking among adolescents. Authoritarian, indulgent, and negligent parenting styles were associated with 1.50-, 2.51-, and 2.82-fold increases in prevalence of adolescent binge drinking, and parental drunkenness, with a 1.99-fold increase. The non-authoritative parenting style made a larger contribution than parental drunkenness to adolescent binge drinking.
CONCLUSIONS: Non-authoritative parenting style and parental drunkenness seem to play an important role in adolescents' binge drinking behavior. At the population level, parenting style appears associated with a greater contribution to this behavior among adolescents. Prevention strategies targeting parental drunkenness may be bolstered if a broader approach including parenting styles is in place.

Evaluation of affective temperament and anxietydepression levels in fibromyalgia patients: a pilot study
Selen Işık-Ulusoy
Abstract

OBJECTIVE: Fibromyalgia (FM) patients have higher rates of depression and anxiety disorders than healthy controls. Affective temperament features are subclinical manifestations of mood disorders. Our aim was to evaluate the affective temperaments of FM patients and investigate their association with depression and anxiety levels and clinical findings.
METHODS: This cross-sectional study included FM patients and healthy controls. The Hospital Anxiety and Depression Scale (HADS) was used to determine patient anxiety and depression levels, and the Temperament Scale of Memphis, Pisa and San Diego, self-administered version was applied to assess affective temperaments in all subjects. Disease severity was assessed in FM patients with the Fibromyalgia Criteria and Severity Scales and the Fibromyalgia Impact Questionnaire (FIQ). Differences between groups were evaluated using Student's t-tests. Correlations among parameters were performed.
RESULTS: This study involved 38 patients with FM (30 female) and 30 healthy controls (25 female). Depressive, anxious and cyclothymic temperaments were significantly higher in FM patients than healthy controls. Statistically significant positive correlations were found between HADS depression score and all temperaments except hyperthymic, as well as between HADS anxiety score and cyclothymic and anxious temperaments. HADS depression and anxiety scores were correlated with symptom severity. We found a higher risk of depression and anxiety among FM patients with higher FIQ scores.
CONCLUSION: This study is the first to evaluate affective temperament features of FM patients. Evaluating temperamental traits in FM patients may help clinicians determine which patients are at risk for depression and anxiety disorders.

Abstract

OBJECTIVE: To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organization's Quality of Life Instrument - Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF).
METHODS: In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-form SRPB, the Brief Religious-Spiritual Coping Scale (RCOPE), and the Beck Depression Inventory (BDI). Priority was given to the 9-item SRPB assessment: its unidimensionality was tested through confirmatory factor analysis and Rasch analysis.
RESULTS: Confirmatory factor analysis of the 9-item SRPB assessment indicated an adjusted model with acceptable fit to data. In the Rasch analysis, general fit measures showed adequate performance. The 9-item SRPB assessment showed good internal consistency (alpha = 0.85), and could differentiate (discriminant validity) between religious and atheist/agnostic respondents (mean = 74.7±14.1 and 56.8615.5, respectively; t = 6.37; degrees of freedom [df] = 402; p < 0.0l) and between non-depressed and depressed respondents (mean = 76.5±12.9 and 67.1 ±16.5; t = 5.57; df = 190.5; p < 0.01). Correlations (convergent validity) were significant with the positive-RCOPE subscale (r = 0.58, p < 0.01) and the WHOQOL-BREF domains (Pearson coefficient ranging between 0.24 and 0.49; p < 0.01), but were in the negative direction with the negative-RCOPE subscale (r = -0.10, p < 0.05). Correlation with the long-form SRPB domain (r = 0.934) was almost perfect.
CONCLUSION: The Brazilian Portuguese 9-item SRPB has good psychometric properties and confirmed the findings of the long-form Brazilian Portuguese version and the abbreviated English version.

Predictors of quality of life in Brazilian medical students: a systematic review and meta-analysis
Ana C. Solis; Francisco Lotufo-Neto
Abstract

OBJECTIVE: To examine predictors associated with quality of life (QoL) in Brazilian medical students.
METHODS: PubMed, PsycINFO, EMBASE, LILACS, and Google Scholar were searched for research articles in English or Portuguese published through August 2018. Observational studies that measured QoL with standard instruments were selected. Three instruments were used to evaluate QoL: the World Health Organization QoL questionnaires (WHOQOL-Bref and WHOQOL-100) and 36-item Short Form Health Survey (SF-36). Hedges' g was used to calculate effect sizes. A random-effects model was used in meta-analyses. PRISMA guidelines were followed.
RESULTS: The initial search retrieved 8,504 articles; 24 met the eligibility criteria for systematic review, and seven for meta-analyses of gender (n=3,402 students). Predictors of QoL such as gender, years of medical school(years of study), economic class, educational environment, academic efficacy, depression, burnout, resilience, empathic concern, sleep difficulties, chronic illness, body mass index, and leisure-time physical activity were identified in the systematic review. The most frequent predictors of QoL detected in Brazilian medical students were associated with gender and years of study.
CONCLUSIONS: Female medical students had lower QoL scores in the physical health and psychological domains of WHOQOL-Bref compared to male students. Specific interventions should be designed for this group as appropriate.

Efficacy and safety of paliperidone palmitate 3-month formulation in Latin American patients with schizophrenia: A subgroup analysis of data from two large phase 3 randomized, double-blind studies
Adam J. Savitz; Haiyan Xu; Srihari Gopal; Isaac Nuamah; Maju Mathews; Bernardo Soares
Abstract

OBJECTIVE: To analyze the efficacy and safety of paliperidone palmitate 3-monthly (PP3M) in Latin American patients with schizophrenia vs. rest-of-world (ROW).
METHODS: We analyzed data from two multinational, double-blind (DB), randomized, controlled phase 3 studies including patients with schizophrenia (DSM-IV-TR) previously stabilized on PP1M/PP3M (open-label [OL] phase). Patients were randomized to PP3M or PP1M (noninferiority study A) and PP3M or placebo (study B) in DB phase. The subgroup analysis included Latin American (Argentina, Brazil, Colombia, Mexico) patients. Primary efficacy endpoints were relapse-free rates (study A) and time-to-relapse (study B).
RESULTS: In study A, 63/71 (88.7%) and in study B 38/43 (88.4%) Latin American patients completed the DB phase. In study A, relapse-free percentage was similar in Latin America (PP3M: 97%, PP1M: 100%) and ROW (PP3M: 91%, PP1M: 89%). In study B, median time-to-relapse was not estimable in the Latin American subgroup for either placebo or PP3M groups, nor for the ROW PP3M group; the median time-to-relapse in the ROW placebo group was 395 days. Caregiver burden improved in patients switching from oral antipsychotics (OL baseline) to PP3M/PP1M in DB phase (Involvement Evaluation Questionnaire score mean ± SD change, -9.4±15.16; p < 0.001). Treatment emergent adverse events with PP3M during DB phase were similar in Latin America (study A: 24/34 [70.6%]; study B: 15/21 [71.4%]) and ROW (study A: 318/470 [67.7%]; study B: 84/139 [60.4%]) subgroups.
CONCLUSION: PP3M was efficacious and showed no new safety concerns in patients with schizophrenia from Latin America, corroborating ROW findings.

Semantic memory, but not education or intelligence, moderates cognitive aging: a cross-sectional study
Laiss Bertola; Rafaela T. Ávila; Maria Aparecida C. Bicalho; Leandro F. Malloy-Diniz
Abstract

OBJECTIVE: Aging studies regularly assume that years of education are a protective factor for baseline cognition. In developing countries with specific sociocultural issues, this relationship may not work as expected, and an unmet need remains for alternative resilience factors. This study aimed to analyze different moderators for the relationship between aging and general cognition that could reflect better protective factors.
METHODS: One hundred and fourteen Brazilian older adults, deemed healthy by global cognition, absence of psychiatric symptoms, or neurological history, participated in this cross-sectional study. Moderators for the relationship between age and global cognition included education, intelligence, and occupational factors. Semantic memory was added as a protective factor reflecting culturally acquired conceptual knowledge.
RESULTS: As expected, age alone is a predictor of global cognitive scores; surprisingly, however, education, intelligence, and occupation were not moderators of the association. Semantic memory was a significant moderator (p = 0.007), indicating that knowledge acquired during life may be a protective factor.
CONCLUSION: In developing countries, the use of resilience factors based only on years of education may be misleading. Sociocultural issues influence the educational system and achievement and, consequently, affect the use of this simple measure. Resilience-factor studies should consider using crystallized abilities when studying populations with sociocultural particularities.

Contextual risk factors of depression and suicidal thoughts in Brazilian adults: a multilevel analysis
Marina X. Carpena; Thais Martins-Silva; Francine S. Costa; Rodrigo Darley; Christian Loret de Mola
Abstract

OBJECTIVE: To evaluate the association between social and health contextual variables, and between major depressive episodes (MDE) and suicidal thoughts in Brazilian adults.
METHODS: This population-based cross-sectional study used data from the 2013 National Health Survey (Pesquisa Nacional de Saúde). The Patient Health Questionnaire was used to evaluate the presence of MDE and suicidal thoughts. We used number of Family Health Strategy teams (FHS) per 20,000 state population, number of Psychosocial Care Centers (Centros de Atenção Psicossocial [CAPS]) per 1,000 state population, gross domestic product (GDP), and Gini index for each Brazilian state as contextual variables. Multilevel logistic regression models were used to calculate OR and the intraclass correlation coefficient (ICC).
RESULTS: Prevalence of MDE and suicidal thoughts was 4.1% (95%CI 3.8-4.4) and 3.8% (95%CI 3.5-4.1), respectively. Multilevel regression models showed an ICC of 1.1% for MDE (95%CI 0.5-2.3) and 1.3% for suicidal thoughts (95%CI 0.6-2.6). Neither GDP, Gini, FHS, or CAPS showed evidence of association with the outcomes.
CONCLUSIONS: In general, contextual variables, within each Brazilian state, do not seem to affect the prevalence of MDE and suicidal thoughts.

Abstract

OBJECTIVE: To evaluate whether exposing rats to individual or combined environmental stressors triggers endophenotypes related to mood and anxiety disorders, and whether this effect depends on the nature of the behavior (i.e., innate or learned).
METHODS: We conducted a three-phase experimental protocol. In phase I (baseline), animals subjected to mixed schedule of reinforcement were trained to press a lever with a fixed interval of 1 minute and a limited hold of 3 seconds. On the last day of phase I, an open-field test was performed and the animals were divided into four experimental groups (n=8/group). In phase II (repeated stress), each group was exposed to either hot air blast (HAB), paradoxical sleep deprivation (PSD) or both (HAB+PSD group) on alternate days over a 10-day period. Control group animals were not exposed to stressors. In phase III (post-stress evaluation), behavior was analyzed on the first (short-term effects), third (mid-term effects), and fifth (long-term effects) days after repeated stress.
RESULTS: The PSD group presented operant hyperactivity, the HAB group presented spontaneous hypoactivity and anxiety, and the HAB+PSD group presented spontaneous hyperactivity, operant hypoactivity, impulsivity, loss of interest, and cognitive impairment.
CONCLUSION: A combination of environmental stressors (HAB and PSD) may induce endophenotypes related to bipolar disorder.

Effects of lithium on inflammatory and neurotrophic factors after an immune challenge in a lisdexamfetamine animal model of mania
Giovana Bristot; Bruna M. Ascoli; Ellen Scotton; Luiza P. Géa; Bianca Pfaffenseller; Márcia Kauer-Sant'Anna
Abstract

OBJECTIVE: To evaluate whether an animal model of mania induced by lisdexamfetamine dimesylate (LDX) has an inflammatory profile and whether immune activation by lipopolysaccharides (LPS) has a cumulative effect on subsequent stimuli in this model. We also evaluated the action of lithium (Li) on inflammatory and neurotrophic factors.
METHODS: Adult male Wistar rats were subjected to an animal model of mania. After the open-field test, they were given LPS to induce systemic immune activation. Subsequently, the animals' blood was collected, and their serum levels of brain-derived neurotrophic factor and inflammatory markers (tumor necrosis factor [TNF]-α, interleukin [IL]-6, IL-1β, IL-10, and inducible nitric oxide synthase [iNOS]) were measured.
RESULTS: LDX induced hyperactivity in the animals, but no inflammatory marker levels increased except brain-derived neurotrophic factor (BDNF). Li had no effect on serum BDNF levels but prevented iNOS levels from increasing in animals subjected to immune activation.
CONCLUSION: Although Li prevented an LPS-induced increase in serum iNOS levels, its potential antiinflammatory effects in this animal model of mania were conflicting.

Psychological distress among transgender people in Brazil: frequency, intensity and social causation - an ICD-11 field study
Maria I. Lobato; Bianca M. Soll; Angelo Brandelli Costa; Alexandre Saadeh; Daniel A.M. Gagliotti; Ana Fresán; Geoffrey Reed; Rebeca Robles
Abstract

OBJECTIVE: To describe self-reported experiences of gender incongruence related to discomfort and body changes to be more congruent to the desired gender, and to examine whether experiences of psychological distress related to gender identity were more strongly related to the experience of gender incongruence per se or to experiences of social rejection.
METHODS: This field study used a structured interview design in a purposive sample of transgender adults (aged > 18 years or older) receiving health-care services in two main reference centers in Brazil.
RESULTS: A high proportion of participants (90.3%, n=93) reported experiencing psychological distress related to their gender identity and report having experienced social rejection related to their gender identity during the interview index period and that rejection by friends was the only significant predictor for psychological distress.
CONCLUSIONS: Gender incongruence variables were not significant predictors of distress. This result supports the recent changes proposed by the Word Health Organization in ICD-11 to move transgender conditions from the Mental and Behavioral Disorders chapter to a new chapter on Sexual Disorders and Conditions Related to Sexual Health.

Pharmacokinetics of antidepressants in patients undergoing hemodialysis: a narrative literature review
Juliana L. Constantino; Vilma A. Fonseca
Abstract

We conducted a narrative literature review on studies that specifically addressed the pharmacokinetics of antidepressants in patients on hemodialysis. The search included the MEDLINE, LILACS, and Web of Knowledge databases and combined Medical Subject Headings and free-text search terms for chronic kidney disease, end-stage renal disease, renal replacement therapy, depression, and antidepressants; it was limited to studies conducted in humans, with no language or time constraints. The search yielded 212 studies. After screening titles and abstracts, 32 studies were read in full and 11 ultimately met the inclusion criteria and were included in the review. Most of the studies showed no difference in the pharmacokinetics of antidepressant drugs between patients with normal renal function and patients undergoing hemodialysis. However, studies with fluvoxamine and amitriptyline showed that variations in albumin levels might affect serum concentrations of these agents. The included studies have several limitations, and there are many obstacles to the adequate treatment of depression in patients undergoing hemodialysis. Further studies on this topic are needed to support proper treatment of these patients, improving their quality of life and reducing mortality.

Aggression directed towards others vs. aggression directed towards the self: clinical differences between intermittent explosive disorder and nonsuicidal self-injury
Gustavo C. Medeiros; Liliana Seger-Jacob; Anna K. Garreto; Hyoun S. Kim; Emil F. Coccaro; Hermano Tavares
Abstract

OBJECTIVE: To investigate the clinical differences between intermittent explosive disorder (IED) (disorder of aggression primarily directed towards others) and nonsuicidal self-injury (NSSI) (disorder of aggression predominantly directed towards the self) in order to better understand the different clinical subtypes of aggression.
METHODS: We used treatment-seeking samples to compare demographic and clinical correlates between 82 participants with IED and 55 participants with NSSI.
RESULTS: The IED group was older, more likely to be male, in a relationship, and employed than the NSSI group. With respect to clinical variables, the NSSI group had more severe depressive symptoms and more social adjustment difficulties. Regarding psychiatric co-morbidities, the IED group had higher rates of generalized anxiety disorder. On the other hand, the NSSI group had higher rates of major depressive disorder, agoraphobia, substance use disorder, and bulimia nervosa.
CONCLUSIONS: Individuals with NSSI may benefit from better management of psychiatric comorbidities, specifically depressive symptoms and social adjustment difficulties. Conversely, the treatment of individuals with IED may be improved by targeting comorbid generalized anxiety disorder. Our results provide important insight for the development of tailored interventions for specific subtypes of aggression.

Abstract

OBJECTIVE: To present the essential guidelines for pharmacological management of patients with psychomotor agitation in Brazil.
METHODS: This is a systematic review of articles retrieved from the MEDLINE (PubMed), Cochrane Database of Systematic Reviews, and SciELO databases published from 1997 to 2017. Other relevant articles in the literature were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools.
RESULTS: Of 5,362 articles retrieved, 1,731 abstracts were selected for further reading. The final sample included 74 articles that met all inclusion criteria. The evidence shows that pharmacologic treatment is indicated only after non-pharmacologic approaches have failed. The cause of the agitation, side effects of the medications, and contraindications must guide the medication choice. The oral route should be preferred for drug administration; IV administration must be avoided. All subjects must be monitored before and after medication administration.
CONCLUSION: If non-pharmacological strategies fail, medications are needed to control agitation and violent behavior. Once medicated, the patient should be monitored until a tranquil state is possible without excessive sedation.

Renata R. Abdalla; André C. Miguel; Elisa Brietzke; Raul Caetano; Ronaldo Laranjeira; Clarice S. Madruga
Abstract

OBJECTIVE: To investigate the prevalence rates of suicidal ideation (SI) and suicide attempts (SA) and their association with substance use in a nationally representative sample of Brazilians.
METHODS: The Second Brazilian National Alcohol and Drug Survey (II BNADS) is a household crosssectional survey that investigated the consumption of psychotropic drugs and associated risk factors. This national probability sample survey used a multistage cluster design to select 4,607 participants aged 14 or older and had a total response rate of 77%. Illegal drug use, SI and SA were obtained by confidential self-report assessment.
RESULTS: SI and SA were reported by 9.9 and 5.4% of the sample, respectively. This prevalence was 20.8 and 12.4% among individuals with alcohol use disorders (AUD), 31.5 and 16.5% among cannabis users and 40.0 and 20.8% among cocaine users. After adjusting for demographic characteristics, tobacco use, family history of suicide and depression, both SI and SA were positively associated with AUD, cannabis and cocaine use.
CONCLUSION: AUD, cannabis and cocaine use were significantly associated with SI and SA, even after the adjustments. Public health initiatives targeting suicide prevention should consider including assessment and management of substance misuse, and therapeutic approaches to substance misuse should include assessment of suicidality.

Abstract

OBJECTIVE: The Montgomery-Åsberg Depression Rating Scale (MADRS) is widely used to assess depression severity. The Structured Interview Guide for the MADRS (SIGMA) was created to standardize MADRS assessment. The objective of this study was to translate and validate the original SIGMA into a Brazilian Portuguese version (SIGMA-VB).
METHODS: We translated and cross-culturally validated the original SIGMA into the SIGMA-VB, and assessed its psychometric properties using data from 93 adult outpatients enrolled in the Integral Assessment in Unipolar Depression (AIUNI) trial. Participants were assessed by two raters on five visits over 8 weeks. We calculated multiple interrater reliability indexes for the SIGMa-VB and used the Hamilton Depression Hating Scale (HAM-D) for validation purposes.
RESULTS: According to the SIGMA-VB, participants had moderate depression at baseline followed by mild depression at 8 weeks. We found over 90% of correlation between scores attributed by different raters using the SIGMA-VB. Correlations between the SIGMA-VB and the HAM-D were above 66%.
CONCLUSION: Our findings confirm that the SIGMA-VB is a valid and reliable instrument to assess depression severity in clinical research and practice. Its interrater reliability was similar to that of a previously published Japanese version of the SIGMA.

Abstract

OBJECTIVE: To examine the psychometric properties of the Chinese version of the Yale-Brown Obsessive Compulsive Scale - Second Edition (Y-BOCS-II).
METHOD: A total of 86 adults with a primary diagnosis of obsessive-compulsive disorder (OCD), ranging in age from 15 to 78 years, participated in the study. Participants were administered the Y-BOCS-II by a trained clinician who also rated overall illness severity on two additional measures. Patients completed the Obsessive Compulsive Inventory-Revised and Depression Anxiety Stress Scale-21.
RESULTS: Results indicated high internal consistency and fair 1-week test retest reliability. The Y-BOCS-II scales correlated strongly with clinician-rated obsessive-compulsive severity and modestly with self-reported obsessive-compulsive symptom frequency and distress. The relationship between Y-BOCS-II total score and depressive and anxiety symptoms was strong, which may reflect high rates of comorbid conditions in this sample or the linkage between obsessive-compulsive symptom severity and distress. Factor analysis demonstrated a two-factor structure consisting of obsession and compulsion factors, with interference due to obsessions cross-loading.
CONCLUSIONS: Overall, these results support the use of the Y-BOCS-II among individuals from China. Future study by an independent group is necessary to replicate these findings, as well as investigate interrater reliability and treatment sensitivity.

Psychological morbidity is the main predictor of quality of life among caregivers of individuals in first-episode psychosis: data from a year-long longitudinal study in Brazil
Rita de C. Jorge; Hugo Cogo-Moreira; Ary G. Araripe Neto; Ana C. Chaves
Abstract

OBJECTIVE: To investigate quality of life (QoL) and QoL predictors among caregivers of individuals in first-episode psychosis (FEP).
METHODS: This longitudinal study investigated predictors of QoL in caregivers of 80 individuals in FEP over a 1-year follow-up period, measured using a single component extracted from the 36-item Short-Form Health Survey (SF-36).
RESULTS: Mediation analysis demonstrated that, at 1 year, high scores in the Self-Report Questionnaire (SRQ-20) were associated with high scores on the negative sub-scale of the Experience of Caregiving Inventory (ECI), which was also associated with low scores in the Essential Quality of Life (Essential QoL) component extracted from the SEF-36. Clinically, the resulting association indicates that depression and anxiety symptoms in caregivers at baseline are predictors of their 1-year quality of life, based on self-assessment of the caregiving experience.
CONCLUSION: Supporting an individual in FEP can have a negative impact on QoL. Maintaining caregivers' mental health and subjective evaluation of the caregiving experience must be primary goals of FEP services. Complementary studies of FEP caregivers' QoL can support the design of personalized interventions in the near future.

The association between adolescent suicide rates and socioeconomic indicators in Brazil: a 10-year retrospective ecological study
Denisse Jaen-Varas; Jair J. Mari; Elson Asevedo; Rohan Borschmann; Elton Diniz; Carolina Ziebold; Ary Gadelha
Abstract

OBJECTIVE: To examine suicide rates among adolescents from six large cities in Brazil and to analyze the relationship between adolescent suicide rates and socioeconomic indicators between 2006 and 2015.
METHODS: Generalized estimating equation models were used to assess the impact of socioeconomic factors - including social inequality and unemployment rates - on adolescent suicide rates.
RESULTS: The rate of adolescent suicide increased by 24% over the course of the study period. Social inequality (assessed using the Gini index), was positively associated with overall adolescent suicide rates (β = 10.68; 95%CI = 2.32-19.05; p ≤ 0.012). After disaggregating the findings by age (10-14 and 15-19 years), social inequality was associated with suicide rate only for adolescents aged 15-19 years (β = 9.63; 95%CI = 2.31-16.96; p p 0.005). Disaggregating these findings by sex, the association with economic variables became significant only among females. Males had a higher overall suicide rate than females, and the highest rate was observed in male adolescents aged 15-19 years. Higher levels of unemployment were associated with higher suicide rates.
CONCLUSION: Our findings suggest that socioeconomic indicators, particularly unemployment and social inequality, are relevant social determinants of suicide in adolescence.

Trends in suicide rates in Brazil from 1997 to 2015
Cássio D. Rodrigues; Débora S. de Souza; Henrique M. Rodrigues; Thais C.R.O. Konstantyner
Abstract

OBJECTIVES: To analyze time trends of suicide rates in Brazil overall and in Brazilian states and compare the estimated suicide rates projected for 2020 with the World Health Organization (WHO) Mental Health Action Plan target.
METHODS: This was an ecological time-series study from 1997 to 2015, stratified by Brazilian states, specific age groups, and sex. Data were obtained from the Mortality Information System (Sistema de Informações sobre Mortalidade [SIM]) of the Brazilian Ministry of Health. Polynomial regression models were used to analyze the trends in suicide rates and to project suicide rates for 2020.
RESULTS: Considering 224 units of analysis, 21 (9.4%) showed a decreasing trend, 108 (48.2%) were stable, and 95 (42.4%) showed an increasing trend. Thus, 67% of units of analysis will not meet the WHO target in 2020. Mean suicide rates were higher in males than in females. People aged 60 years and older presented the highest suicide rates, while 84.7% of total deaths by suicide occurred among 15-to-59-year-olds.
CONCLUSION: Overall, 90.6% of units of analysis had a stable or increasing trend in suicide rates from 1997 to 2015. If these trends remain, most of Brazil will fail to achieve the WHO-recommended reduction in suicide rates by 2020.

William Sperb; Jandilson A. da Silva; Hugo Cogo-Moreira; Diogo R. Lara; Hudson W. de Carvalho
Abstract

OBJECTIVE: The current study aimed to examine the latent structure of a web-based, Brazilian Portuguese version of the Young Schema Questionnaire-Short Form (YSQ-SF).
METHOD: The sample consisted of 15,557 adult participants - 4,702 men and 10,855 women - with age ranging from 18 to 60 years. Confirmatory factor analysis was used to test the a priori conceptual 15-factor model presumed to underlie the YSQ-SF item set.
RESULTS: Most items displayed high levels of reliability (factor loadings greater than 0.7) and low liability to random measurement error (residual variances below 0.02), indicating that the a priori YSQ-SF factor structure is adequate.
DISCUSSION: These findings offer empirical evidence supporting YSQ-SF construct validity and, consequently, its application in adults.

Sociodemographic, behavioral, and health-related risk factors for depression among men and women in a southern Brazilian city
Marina X. Carpena; Samuel C. Dumith; Christian Loret de Mola; Lucas Neiva-Silva
Abstract

OBJECTIVE: To assess the prevalence of depression and sociodemographic, behavioral, and health-related risk factors therefor in a southern Brazilian city.
METHODS: Population-based, cross-sectional study of adults from Rio Grande, state of Rio Grande do Sul, Brazil. Individuals (n=1,295) were selected using a multistage sampling procedure. The Patient Health Questionnaire-9 (PHQ-9) was used to screen for major depressive episodes (MDEs). We used a conceptual causal framework to organize and assess risk factors for MDE and calculated prevalence ratios (PR) using regression models.
RESULTS: The prevalence of MDE was 8.4% (95%CI 6.0-10.7) for men and 13.4% (95%CI 11.0-15.8) for women. For men, physical inactivity (PR 2.34, 95%CI 1.09-5.00) and perceived stress (PR 20.35, 95%CI 5.92-69.96) were associated with MDe. In women, MDE prevalence was higher among those in the first tertile of economic index (PR 2.61, 95%CI 1.53-4.45), with 0-8 years of schooling (PR 2.25, 95%CI 1.24-4.11), alcohol users (PR 1.91, 95%CI 1.21-3.02), those physically inactive (PR 2.49, 95%CI 1.22-5.09), with the highest perceived stress (PR 9.17, 95%CI 3.47-24.23), with another mental disorder (PR 1.85, 95%CI 1.32-2.59), and with more noncommunicable diseases (PR 1.85, 95%CI 1.06-3.22).
CONCLUSION: Women had a higher prevalence of depression, and socioeconomic disadvantages were important for the occurrence of MDE; however, for men, only physical inactivity and stress were important predictors, suggesting possible different causal pathways for each sex.

Abstract

OBJECTIVE: We examined the sociodemographic factors associated with smoking risk perceptions (SRP) in youth living in two very different neighborhoods in the city of São Paulo, Brazil: a middle-class central area (Vila Mariana) and a poor outer-city area (Capão Redondo).
METHODS: A cross-sectional survey was conducted with 180 public school-attending youth (all aged 12 years) and their parents. SRP was evaluated through self-reports. Weighted multinomial logistic regression was used to examine factors associated with SRP.
RESULTS: Smoking was considered a high-risk behavior by 70.9% of adolescents. There were significant differences in SRP associated with socioeconomic status (SES) and maternal smoking status. Having a non-smoking mother was positively associated with perceiving smoking as having low to moderate risk versus no risk (OR=3.91 [95%CI 1.27-12.02]). Attending school in Capão Redondo was associated with perceiving smoking as having high risk compared to no risk (OR=3.00 [95%CI 1.11-8.12]), and low SES was negatively associated with perceiving at least some risk in smoking versus perceiving no risk in this behavior.
CONCLUSIONS: Youth whose mothers smoke appear to have lower SRP than those whose mothers do not smoke. Living in a poor outer-city area was associated with higher SRP.

Abstract

OBJECTIVE: Our study aimed to verify whether cyberbullying victimization among adolescents occurs concomitantly with other forms of violence exposure (at home, at school and in the community).
METHODS: A collaborative longitudinal study by Norwegian and Brazilian researchers was conducted in Itaboraí, a low-income city in southeast Brazil. At baseline, trained interviewers applied a semi-structured questionnaire to a population-based sample of 669 in-school adolescents (11-15 years old). The investigated types of violence exposure included cyberbullying, traditional bullying, severe physical punishment by parents and community violence (victimization and eye-witnessed violent events outside the home and school).
RESULTS: In the previous six months, 1.9% of the adolescents had been victims of cyberbullying, and 21.9% had been victims of physical aggression, verbal harassment and/or social manipulation by peers. However, only 5.5% of the adolescents considered themselves bullying victims. In the previous 12 months, 12.4% of adolescents had suffered severe physical punishment, 14.0% had been victims of community violence, and 20.9% eye-witnessed community violence. Multivariable regression analysis showed that victimization by multiple types of traditional bullying and self-perceived bullying victimization were correlates of cyberbullying victimization, while suffering violence at home and in the community were not.
CONCLUSION: This study provides evidence of an association between cyberbullying, traditional bullying and self-perceived bullying among low-income Brazilian adolescents.

Abstract

OBJECTIVE: To perform a cost-effectiveness analysis of donepezil and rivastigmine therapy for mild and moderate Alzheimer's disease (AD) from the perspective of the Brazilian Unified Health System.
METHOD: A hypothetical cohort of 1,000 individuals of both sexes, aged >65 years, and diagnosed with AD was simulated using a Markov model. The time horizon was 10 years, with 1-year cycles. A deterministic and probabilistic sensitivity analysis was performed.
RESULTS: For mild AD, the study showed an increase in quality-adjusted life years (QALYs) of 0.61 QALY/21,907.38 Brazilian reais (BRL) for patients treated with donepezil and 0.58 qAlY/BRL 24,683.33 for patients treated with rivastigmine. In the moderate AD group, QALY increases of 0.05/BRL 27,414.96 were observed for patients treated with donepezil and 0.06/BRL 34,222.96 for patients treated with rivastigmine.
CONCLUSIONS: The findings of this study contradict the standard of care for mild and moderate AD in Brazil, which is based on rivastigmine. A pharmacological treatment option based on current Brazilian clinical practice guidelines for AD suggests that rivastigmine is less cost-effective (0.39 QALY/BRL 32,685.77) than donepezil. Probabilistic analysis indicates that donepezil is the most cost-effective treatment for mild and moderate AD.

Abstract

OBJECTIVE: To estimate the 12-month prevalence of mental health services utilization (overall and by type of service sector), the adequacy of treatment provided, and sociodemographic correlates in the Argentinean Study of Mental Health Epidemiology (ASMHE).
METHODS: The ASMHE is a multistage probability household sample representative of adults in urban areas of Argentina. The World Health Organization World Mental Health Composite International Diagnostic Interview (WMH-CIDI) was used to evaluate psychiatric diagnosis and service utilization.
RESULTS: Among those with a disorder, 27.6% received any treatment in the prior 12 months. Of these, 78.3% received minimally adequate treatment using a broad definition and only 43.6% using a stringent definition. For individuals with a disorder, more services were provided by mental health professionals (17.7%) than by general medical professionals (11.5%) or non-healthcare sectors (2.6%). Younger individuals with low education and income were less likely to receive treatment; those never married and those with an anxiety or mood disorder were more likely to receive treatment. Among those in treatment, treatment was least adequate among younger individuals with low education and low income.
CONCLUSIONS: Policies to increase access to services for mental health disorders in Argentina are needed, as is training for primary care practitioners in the early detection and treatment of psychiatric disorders.

Abstract

OBJECTIVE: Bipolar depression is characterized by neurobiological features including perturbed oxidative biology, reduction in antioxidant levels, and a concomitant rise in oxidative stress markers. Bipolar depression manifests systemic inflammation, mitochondrial dysfunction, and changes in brain growth factors. The depressive phase of the disorder is the most common and responds the least to conventional treatments. Garcinia mangostana Linn, commonly known as mangosteen, is a tropical fruit. The pericarp's properties may reduce oxidative stress and inflammation and improve neurogenesis, making mangosteen pericarp a promising add-on therapy for bipolar depression.
METHODS: Participants will receive 24 weeks of either 1,000 mg mangosteen pericarp or placebo per day, in addition to their usual treatment. The primary outcome is change in severity of mood symptoms, measured using the Montgomery-Åsberg Depression Rating Scale (MADRS), over the treatment phase. Secondary outcomes include global psychopathology, quality of life, functioning, substance use, cognition, safety, biological data, and cost-effectiveness. A follow-up interview will be conducted 4 weeks post-treatment.
CONCLUSION: The findings of this study may have implications for improving treatment outcomes for those with bipolar disorder and may contribute to our understanding of the pathophysiology of bipolar depression.

Abstract

OBJECTIVES: To estimate the current prevalence of posttraumatic stress disorder (PTSD) and the diagnosis rate of this disorder ascertained by psychiatrists in training.
METHODS: We interviewed 200 adults under treatment in a university mental health outpatient clinic. The PTSD diagnoses obtained using the Structured Clinical Interview for DSM-IV (SCID-IV) were compared with the patients' medical records.
RESULTS: Forty-one patients (20.5%) were diagnosed with current PTSD, but only one of them (2.4%) had previously received this diagnosis. This study confirms that although PTSD is highly prevalent among mental health outpatients, it is remarkably underdiagnosed in teaching hospitals.
CONCLUSIONS: These findings suggest that psychiatrists in training may be failing to investigate traumatic events and their consequences and strongly indicate that trauma-related issues should be given more prominence in psychiatry curricula and psychiatrist training.

Telomere length and childhood trauma in Colombians with depressive symptoms
Karen M. Jiménez; Angela J. Pereira-Morales; Ana Adan; Diego A. Forero
Abstract

OBJECTIVE: Childhood trauma and telomere length (TL) are important risk factors for major depressive disorder. We examined whether there was an association between childhood trauma and TL in a sample of Colombians who were assessed for depressive symptoms.
METHODS: We applied the Center for Epidemiologic Studies Depression scale, the Patient Health Questionnaire-9, the Hospital Anxiety and Depression scale and the Childhood Trauma Questionnaire to 92 Colombian subjects (mean age = 21). TL was measured with quantitative PCR. Spearman's correlation coefficient (rs) was used to analyze the relationship between childhood trauma scores and TL.
RESULTS: We found a significant correlation between tL and sexual abuse scores (rs = 0.428, p = 0.002) in individuals with higher depressive symptom scores.
CONCLUSION: This is the first report of a significant association between TL and sexual abuse in a Latin American sample and provides additional evidence about the role of childhood trauma and TL in neuropsychiatric disorders.

Abstract

OBJECTIVE: Alzheimer's disease occurs at a higher prevalence and an earlier age in individuals with Down syndrome (DS) than typically developing individuals. However, diagnosing dementia in individuals with intellectual disability remains a challenge due to pre-existing cognitive deficits. The aim of this study was to investigate the validity and reliability of the Brazilian version of the Cambridge Examination for Mental Disorders of Older People with Down's syndrome and Others with Intellectual Disabilities (CAMDEX-DS) for individuals with DS.
METHODS: Two psychiatrists, working independently, evaluated 92 adults with DS ≥ 30 years of age. The concurrent validity of the CAMDEX-Ds was analyzed in relation to the gold standard of established international criteria. In a subgroup of 20 subjects, the concurrent validity of the CAMDEX-DS was analyzed in relation to an independent objective assessment of cognitive decline over three years. We analyzed the inter-rater reliability of cognitive assessment.
RESULTS: The diagnostic accuracy of the CAMDEX-DS compared to the gold standard was 96.7%. CAMDEX-DS-based diagnosis was considered consistent with cognitive decline. The probability of a participant with dementia having cognitive decline was 83%. Inter-rater reliability for the participant assessment was good, with a kappa of > 0.8 for 93% of the CAMDEX-DS items.
CONCLUSION: The CAMDEX-DS can be considered the first valid and reliable instrument for evaluating dementia in adults with DS in Brazil. Its use in such individuals could improve clinical practice and research.

Abstract

OBJECTIVE: To estimate the prevalence of major depressive episode (MDE) in patients with presumptive pulmonary tuberculosis (pre-PTB, defined by cough lasting ≥ 3 weeks) and compare it between patients with pulmonary tuberculosis (PTB) and without PTB.
METHODS: Patients with pre-PTB (n=260) were screened for depression using the Patient Health Questionnaire (PHQ-9). Those individuals with scores ≥ 10 were subsequently assessed with the depression module of the Mini International Neuropsychiatric Interview (MINI-Plus) to confirm diagnosis. Associations of categorical variables with PTB and MDE were calculated using the chi-square test and OR.
RESULTS: PTB was confirmed in 98 patients (37.7%). A high proportion of both groups (active PTB and no PTB) screened positive for depression (60.2 vs. 62.1%, respectively). Among 159 patients who screened positive for depression, a subset of 97 (61.0%) were further evaluated with the MINI-Plus; current mDe was confirmed in 54.6% (53/97). On univariate and multivariate analysis, female sex was the only factor associated with the diagnosis of current MDE (p = 0.04).
CONCLUSION: The prevalence of MDE was high among individuals with prolonged respiratory symptoms, independent of PTB diagnosis. This is consistent with other studies of depression in primary care in Brazil.

Abstract

OBJECTIVE: The incidence rate of major depression in adolescents reaches approximately 14%. This disorder is usually recurrent, without remission of symptoms even after pharmacological treatment, and persists throughout adult life. Since the effects of antidepressants take approximately 2 weeks to begin, new pharmacological therapies are under continuous exploration. Recent evidence suggests that psychedelics could produce rapid antidepressant effects. In this study, we evaluated the potential antidepressant effects of ayahuasca in a juvenile non-human primate model of depression.
METHODS: While living with their families, juvenile marmosets (8 males; 7 females) were observed on alternate days for four weeks during a baseline phase. This was followed by 8 weeks of an induced depressive state protocol, the social isolated context (IC), in which the animals were monitored in the first and last weeks. Subsequently, five males and four females were randomly selected for treatment, first with a single administration of saline vehicle (1.67 mL/300 g of body weight, via gavage), followed by a single dose of ayahuasca (1.67 mL/300 g of body weight, via gavage). Both phases lasted 1 week and the animals were monitored daily. A third week of sampling was called the tardive-pharmacological effects phase. In all phases the marmosets were assessed for behavior, fecal cortisol levels, and body weight.
RESULTS: After IC, the animals presented typical hypocortisolemia, but cortisol recovered to baseline levels 24 h after an acute dose of ayahuasca; this recovery was not observed in vehicle-treated animals. Additionally, in males, ayahuasca, but not the vehicle, reduced scratching, a stereotypic behavior, and increased feeding. Ayahuasca treatment also improved body weight to baseline levels in both sexes. The ayahuasca-induced behavioral response had long-term effects (14 days). Thus, in this translational juvenile animal model of depression, ayahuasca presented beneficial effects.
CONCLUSIONS: These results can contribute to the validation of ayahuasca as an antidepressant drug and encourage new studies on psychedelic drugs as a tool for treating mood disorders, including for adolescents with early-onset depression.

Abstract

OBJECTIVE: To investigate the prevalence of early childhood maltreatment and associations with later sexual behavior among adult substance users.
METHODS: A cross-sectional study enrolled 134 substance dependents who sought outpatient care in São Paulo, Brazil. Childhood trauma prevalence was assessed using the Childhood Trauma Questionnaire (CTQ). The Sexual Addiction Screening Test (SAST), drug of choice (DOC), and sexual behavior were also investigated.
RESULTS: The sample was composed predominantly of single adult males (76.1%), with alcohol as the DOC (73.9%). Experiences of emotional neglect (88.1%), emotional abuse (80.6%), physical neglect (78.4%), physical abuse (64.2%), and sexual abuse (31.3%) were prevalent. Women were more likely to have been sexually abused (OR 2.9, 95%CI 1.15-7.61) and physically abused (OR 3.7, 95%CI 1.31-10.6) in childhood. Those who were sexually abused in adulthood were more likely to have suffered physical abuse in childhood (OR 6.9, 95%CI 1.45-11.8). The odds of having been sexually abused in childhood were higher among subjects who reported to have exchanged sexual favors for drugs (OR 5.7, 95%CI 1.35-9.64) and to have been sexually abused in adulthood (OR 6.1, 95%CI 5.2-12.36).
CONCLUSION: Physical and sexual abuse in childhood are highly prevalent in substance-dependent adults, and are associated with sexual revictimization and high-risk sexual behavior in adulthood.

Abstract

OBJECTIVE: Bipolar disorder (BD) is highly heritable. The present study aimed at identifying brain morphometric features that could represent markers of BD vulnerability in non-bipolar relatives of bipolar patients.
METHODS: In the present study, structural magnetic resonance imaging brain scans were acquired from a total of 93 subjects, including 31 patients with BD, 31 non-bipolar relatives of BD patients, and 31 healthy controls. Volumetric measurements of the anterior cingulate cortex (ACC), lateral ventricles, amygdala, and hippocampus were completed using the automated software FreeSurfer.
RESULTS: Analysis of covariance (with age, gender, and intracranial volume as covariates) indicated smaller left ACC volumes in unaffected relatives as compared to healthy controls and BD patients (p = 0.004 and p = 0.037, respectively). No additional statistically significant differences were detected for other brain structures.
CONCLUSION: Our findings suggest smaller left ACC volume as a viable biomarker candidate for BD.

Abstract

OBJECTIVE: Although attentional bias (AB) toward angry faces is well established in patients with anxiety disorders, it is still poorly studied in obsessive-compulsive disorder (OCD). We investigated whether OCD patients present AB toward angry faces, whether AB is related to symptom severity and whether AB scores are associated with specific OCD symptom dimensions.
METHOD: Forty-eight OCD patients were assessed in clinical evaluations, intelligence testing and a dot-probe AB paradigm that used neutral and angry faces as stimuli. Analyses were performed with a one-sample t-test, Pearson correlations and linear regression.
RESULTS: No evidence of AB was observed in OCD patients, nor was there any association between AB and symptom severity or dimension. Psychiatric comorbidity did not affect our results.
CONCLUSION: In accordance with previous studies, we were unable to detect AB in OCD patients. To investigate whether OCD patients have different brain activation patterns from anxiety disorder patients, future studies using a transdiagnostic approach should evaluate AB in OCD and anxiety disorder patients as they perform AB tasks under functional neuroimaging protocols.

Abstract

OBJECTIVE: In Western countries, the prevalence of childhood trauma (CT) ranges from 15 to 25%. CT might be indirectly associated with lower parental socioeconomic status and educational attainments. The aims of this cross-sectional study were fourfold: to assess prevalence of CT in a large sample of Iranian children; to compare the Iranian prevalence rates with those of Western countries; to explore gender-specific patterns; and to explore possible socioeconomic predictors.
METHOD: The sample comprised 608 children (mean age 11.49 years, 51.5% females). All completed the Farsi version of the Trauma Symptoms Checklist for Children. Additionally, parents reported on their current employment status and highest educational level.
RESULTS: Trauma symptoms were reported by 20 of 295 boys and 23 of 313 girls. The overall prevalence was 7.1%. Child-reported trauma symptoms were not associated with parents' socioeconomic status or highest educational level. Compared to prevalence findings from U.S. national surveys (ranging from 15-25% of children and adolescents), the prevalence among 11- and 12-year-olds in the present study was considerably lower.
CONCLUSIONS: The overall prevalence of reported trauma symptoms among a large sample of Iranian children was unrelated to parents' socioeconomic status, and was lower than that reported in U.S. surveys.

From anatomy to function: the role of the somatosensory cortex in emotional regulation
Erika Kropf; Sabrina K. Syan; Luciano Minuzzi; Benicio N. Frey
Abstract

Since the pioneering work of Penfield and his colleagues in the 1930s, the somatosensory cortex, which is located on the postcentral gyrus, has been known for its central role in processing sensory information from various parts of the body. More recently, a converging body of literature has shown that the somatosensory cortex also plays an important role in each stage of emotional processing, including identification of emotional significance in a stimulus, generation of emotional states, and regulation of emotion. Importantly, studies conducted in individuals suffering from mental disorders associated with abnormal emotional regulation, such as major depression, bipolar disorder, schizophrenia, post-traumatic stress disorder, anxiety and panic disorders, specific phobia, obesity, and obsessive-compulsive disorder, have found structural and functional changes in the somatosensory cortex. Common observations in the somatosensory cortices of individuals with mood disorders include alterations in gray matter volume, cortical thickness, abnormal functional connectivity with other brain regions, and changes in metabolic rates. These findings support the hypothesis that the somatosensory cortex may be a treatment target for certain mental disorders. In this review, we discuss the anatomy, connectivity, and functions of the somatosensory cortex, with a focus on its role in emotional regulation.
