Objectives: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression by community-based health workers would decrease behavioral/emotional symptoms in their children. Interventions for maternal depressive symptoms in a low/middle-income country can have a high global impact. Methods: Community-based health workers were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. A total of 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at 6 months follow-up. Child behavioral/emotional symptoms were evaluated according to type of change in maternal depressive symptoms: response or remission. Results: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6 months follow-up were found. Response or remission was associated with better outcomes in child behavioral/emotional symptoms at 6 months follow-up (p = 0.0247, Cohen’s d: 0.76; p = 0.0224, Cohen’s f: 0.44) but not at post-intervention (p = 0.1636, Cohen’s d: 0.48; p = 0.0720, Cohen’s f: 0.33). Conclusions: Improvement in maternal depression was related to decreased behavioral/emotional symptoms in their children. Our results suggest that providing interventions for maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

Objective: Much research has been published on the role of sexual revictimization in the emergence of mental disorders in adulthood, but findings have sometimes been contradictory. The present systematic review sought to assess the state of the evidence on revictimization as a potential factor for the emergence of posttraumatic stress disorder (PTSD). Methods: Electronic searches were conducted in five databases (MEDLINE/PubMed, Cochrane Library, Campbell Library, PsycINFO, and LILACS), using the terms PTSD, posttraumatic stress disorder, child abuse, and rape. Results: We identified nine articles that established a connection among childhood sexual abuse (CSA), sexual revictimization in adulthood, and development of PTSD. Eight of the nine papers included were classified as having strong methodological quality (grade VI). One was classified as IV, with an average quality-of-evidence rating. The mean methodological quality score of the articles was 5.5, and the quality of evidence was deemed strong. Conclusion: In the included studies, PTSD symptoms were most prevalent in the CSA + adult sexual assault groups, providing further evidence for the revictimization hypothesis.

Objective: Associations between parental/caregiver depression and adverse child outcomes are well established and have been described through one or more mechanisms: child psychopathology following exposure to a depressed caregiver, child psychopathology exacerbating a caregiver’s depression, and caregiver and offspring depression sharing the same etiology. Data from low and middle-income countries is scarce. We examined correlations between common symptoms of mental disorders in caregivers and their offspring’s psychopathology in a Brazilian sample. Methods: In this cross-sectional study, adult caregivers were screened for depression during routine home visits by community health workers as part of the Brazilian Family Health Strategy. Caregivers with suspected depression were assessed using the Zung Self-Rating Depression Scale and the Self-Reporting Questionnaire (SRQ-20). Children’s symptoms were evaluated using the Strengths and Difficulties Questionnaire (SDQ). Results: The sample included 68 primary caregivers and 110 children aged 6 to 15 years. Higher caregiver scores on the SRQ-20 correlated significantly with psychiatric symptoms in offspring. Conclusion: These results substantiate our hypothesis that child psychopathology correlates with caregivers’ psychiatric symptoms. This paper adds to the growing literature on community mental health assessment and can help guide future strategies for reducing the burden of common mental disorders in caregivers and children alike in low and middle-income countries.

Objective: Sleep disturbances play a fundamental role in the pathophysiology posttraumatic stress disorder (PTSD), and are not only a secondary feature. The aim of this study was to validate and assess the psychometric properties of the Brazilian version of the Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI-A-BR), a self-report instrument designed to assess the frequency of seven disruptive nocturnal behaviors, in a sample of participants with and without PTSD. Methods: PSQI-A was translated into Brazilian Portuguese and applied to a convenience sample of 190 volunteers, with and without PTSD, who had sought treatment for the consequences of a traumatic event. Results: The PSQI-A-BR displayed satisfactory internal consistency (Cronbach's coefficient of 0.83 between all items) and convergent validity with the Clinician Administered PTSD Scale (CAPS), even when excluding sleep-related items (r = 0.52). Test-retest yielded high agreement in the global PSQI-A-BR, with good stability over time (r = 0.88). A global PSQI-A-BR cutoff score of 7 yielded a sensitivity of 79%, specificity of 64%, and a global score of 7 yielded a positive predictive value of 93% for discriminating participants with PTSD from those without PTSD. Conclusion: The PSQI-A-BR is a valid instrument for PTSD assessment, applicable to both clinical and research settings.

Objective: To ascertain whether genetic variations in the serotonin transporter gene (5-HTTLPR 44-bp insertion/deletion polymorphism) influence an increase in depressive and anxiety symptoms in children and adolescents exposed to high levels of violence. Methods: Saliva samples were collected from a group of children who were working on the streets and from their siblings who did not work on the streets. DNA was extracted from the saliva samples and analyzed for 5-HTTLPR polymorphism genotypes. Results: One hundred and seventy-seven children between the ages of 7 and 14 years were analyzed (114 child workers and 63 siblings). Data on socioeconomic conditions, mental symptoms, and presence and severity of maltreatment and urban violence were collected using a sociodemographic inventory and clinical instruments. There was no positive correlation between the 5-HTTLPR polymorphism and presence of mental symptoms in our sample, although the children were exposed to high levels of abuse, neglect, and urban violence. Conclusions: Despite previous studies that associated adult psychiatric disorders with the 5-HTTLPR polymorphism and a history of childhood maltreatment, no such association was found in this sample of children at risk.

Background: Dimensional models of psychopathology demonstrate that two correlated factors of fear and distress account for the covariation among depressive and anxiety disorders. Nevertheless, these models tend to exclude variables relevant to psychopathology, such as temperament traits. This study examined the joint structure of DSM-IV-based major depression and anxiety disorders along with trait negative affect in a representative sample of adult individuals residing in the cities of São Paulo and Rio de Janeiro, Brazil. Methods: The sample consisted of 3,728 individuals who were administered sections D (phobic, anxiety and panic disorders) and E (depressive disorders) of the Composite International Diagnostic Interview (CIDI) 2.1 and a validated version of the Positive and Negative Affect Schedule. Data were analyzed using correlational and structural equation modeling. Results: Lifetime prevalence ranged from 2.4% for panic disorder to 23.2% for major depression. Most target variables were moderately correlated. A two-factor model specifying correlated fear and distress factors was retained and confirmed for models including only diagnostic variables and diagnostic variables along with trait negative affect. Conclusions: This study provides support for characterization of internalizing psychopathology and trait negative affect in terms of correlated dimensions of distress and fear. These results have potential implications for psychiatric taxonomy and for understanding the relationship between temperament and psychopathology.

Objective: To quantitatively study the exposure to childhood maltreatment and urban violence in children from families with at least one child working on the streets and to investigate the relationship between these factors and street work. Methods: Families who participated in a nongovernmental organization (NGO) program to eliminate child labor were included. Data concerning sociodemographic characteristics, punishment methods used in the family environment against the children, five types of abuse and neglect perpetrated by the caregivers, urban violence exposure and family functioning were collected. Results: The sample included 126 children who were working on the streets and 65 siblings who were not working on the streets. Caregivers reported high levels of severe physical punishment. The children reported high levels of abuse and neglect, and high levels of urban violence exposure. The families showed a predominance of dysfunctional and unsatisfactory relationships. A multiple logistic regression model showed that age older than 12 years and severe physical punishment at home were associated with street work. Conclusion: Interventions to decrease the risk of child street work should be family-focused and should aim to reduce violence in the family environment.

RESUMO Novas evidências sugerem que o cerebelo apresenta alterações estruturais e funcionais nos transtornos psiquiátricos. Objetivo: Medir o volume do cerebelo e de suas sub-regiões em indivíduos portadores de transtornos psiquiátricos e relacionar tais achados aos sintomas. Métodos: Foi realizada a identificação de pacientes com diferentes graus de prejuízo cognitivo proveniente de um estudo populacional (Epidemiologia do Idoso - UNIFESP), pacientes com transtorno do estresse pós-traumático proveniente de outro estudo populacional e portadores de transtorno bipolar proveniente de um ambulatório especializado (Universidade Federal da Bahia). Todos os sujeitos foram submetidos à ressonância magnética estrutural de 1.5T. As medidas de volume, assim como os sintomas medidos por escalas psicométricas foram comparadas entre pacientes e controles. Resultados: Foi observado que o volume do cerebelo está reduzido nos portadores de prejuízo cognitivo sem demência e com demência, no transtorno do estresse pós-traumático e no transtorno bipolar quando comparados aos controles. Na demência e no transtorno do estresse pós-traumático o volume do hemisfério cerebelar esquerdo e do vérmis estão reduzidos. No transtorno bipolar os volumes de ambos os hemisférios e do vérmis estão reduzidos. Nos dois primeiros estudos estas reduções correlacionaram com os sintomas. Conclusão: A natureza exata do envolvimento do cerebelo nos processos mentais ainda não é compreendida. Entretanto, anormalidades na estrutura cerebelar e em suas funções têm sido relatadas em algumas dessas doenças. Pesquisas futuras, com amostras maiores, ainda são necessárias para esclarecer tais achados e investigar se são importantes para o tratamento e prognóstico.

ABSTRACT. New evidence suggests that the cerebellum has structural and functional abnormalities in psychiatric disorders. Objective: In this research, the goal was to measure the volume of the cerebellum and its subregions in individuals with psychiatric disorders and to relate these findings to their symptoms. Methods: Patients with different degrees of cognitive impairment (Epidemiology of the Elderly - UNIFESP) and patients with post-traumatic stress disorder (PTSD) from population studies were analyzed. Also, patients with bipolar disorder from an outpatient clinic (Center for the Study of Mood and Anxiety Disorders, Universidade Federal da Bahia) were recruited for this study. All subjects underwent a 1.5T structural magnetic resonance scan. Volumetric measures and symptom measurements, by psychometric scales, were performed and compared between patients and controls. Results: The cerebellum volume was reduced in patients with cognitive impairment without dementia and with dementia, in patients with PTSD, and in patients with bipolar disorder compared to controls. In dementia and PTSD, the left cerebellar hemisphere and vermis volume were reduced. In bipolar disorder, volumes of both hemispheres and the vermis were reduced. In the first two studies, these cerebellar volumetric reductions correlated with symptoms of the disease. Conclusion: The exact nature of cerebellar involvement in mental processes is still not fully understood. However, abnormalities in cerebellar structure and its functions have been reported in some of these diseases. Future studies with larger samples are needed to clarify these findings and investigate whether they are important for treatment and prognosis.

INTRODUCTION: Depressive disorders (DDs) are very prevalent disorders particularly in women, a high-risk gender group. Determining the risk and protective factors associated with the development of DDs is fundamental to planning preventive and therapeutic strategies. In this study, we evaluated the correlations between healthy maternal attachment and the development of DDs in adulthood. METHODS: We evaluated 52 women at 6 months to 1 year after premature childbirth at Maternidade Vila Nova Cachoeirinha. They were evaluated using the following instruments: Brazilian Criteria of Economic Classification,Parental Bonding Inventory (PBI),Center for Epidemiologic Studies Depression Scale (CES-D), and Edinburgh Postnatal Depression Scale (EPDS). Cut-off scores on the CES-D and EPDS were used to classifythe subjects as currently having a DD or having probable postpartum disorder (PPD) after childbirth. Multiple logistic regression was used to evaluate the risk factors associated with DDs. RESULTS: We found that 49.1% of the sample had a current depressive episode, and 73.6% had probable PPD. Based on logistic regression, current depression (odds ratio = 1.092 [confidence interval: 1.005; 1.186]), and a PPD (odds ratio = 1.108 [confidence interval: 1.011; 1.21]) were negatively correlated with affective maternal relationships. CONCLUSIONS: Women who reported healthy attachment with their mothers did not develop DDs when faced with stressful situations such as premature childbirth.

CONTEXTUALIZAÇÃO: A magnitude das respostas cardiovasculares depende dos componentes estático e dinâmico bem como da duração e intensidade da contração realizada. OBJETIVO: Avaliar as respostas da frequência cardíaca (FC) frente a diferentes percentuais de contração isométrica em 12 pacientes (63±11,6 anos; média±dp) com doença da artéria coronária e/ou fatores de risco para ela, participantes de um programa de reabilitação cardíaca fase III. MÉTODOS: A variação da frequência cardíaca (ΔFC) foi avaliada durante as contrações voluntárias máximas (CVM; 5" e 10" de duração) e submáximas (CVSM; 30 e 60% da CVM-5, até exaustão muscular) de preensão palmar, utilizando-se um dinamômetro (hand grip). Adicionalmente, o RMSSD dos iR-R em ms (índice representante da modulação vagal cardíaca) foi calculado em repouso (pré-contração) nos últimos 30 segundos da CVSM e na recuperação (pós-contração). RESULTADOS: A ΔFC apresentou maiores valores em CVM-10 vs CVM-5 (17±5,5 vs 12±4,2 bpm, p<0,05) e no CVSM-60 vs CVSM-30 (19±5,8 vs 15±5,1 bpm, p<0,05). No entanto, os resultados para CVM-10 mostraram ΔFC similar quando comparados aos resultados obtidos para CVSM (p>0,05). RMSSD de repouso reduziu-se (p<0,05) durante a CVSM-30 (30%=29,9±17,1 vs 12,9±8,5ms) e CVSM-60 (60%=25,8±18,2 vs 9,96±4,2 ms), mas retornou aos valores basais quando a contração foi interrompida. CONCLUSÕES: Em pacientes com doença da artéria coronária e/ou fatores de risco para ela, a contração isométrica de baixa intensidade mantida por longos períodos de tempo apresenta os mesmos efeitos sobre as respostas da FC, quando comparada à contração isométrica de alta ou máxima intensidade, porém de breve duração.

BACKGROUND: The magnitude of cardiovascular responses is dependent on the static and dynamic components as well as the duration and intensity of the contraction performed. OBJECTIVE: To evaluate the heart rate responses to different percentages of isometric contractions in 12 patients (63±11.6 years) with coronary artery disease and/or risk factors for coronary artery disease that were participating in a phase III cardiac rehabilitation program. METHODS: Heart rate variation (ΔHR) was evaluated during maximum (MVC, five and ten seconds in duration) and submaximal (SMVC, 30 and 60% of MVC-5, until muscle exhaustion) voluntary contraction, using a handgrip dynamometer. Additionally, the representative index of cardiac vagal modulation (RMSSD index) was calculated at rest (pre-contraction), at the final 30 seconds of SMVC and during recovery (post-contraction). RESULTS: ΔHR showed higher values in MVC-10 versus MVC-5 (17±5.5 vs 12±4.2 bpm, p<0.05) and the SMVC-60 vs SMVC-30 (19±5.8 vs 15±5.1 bpm, p<0.05). However, results for CVM-10 showed similar ΔHR compared to results for CVSM (p> 0.05). RICVM at rest decreased (p<0.05) during SMVC-30 (30% = 27.9±17.1 vs 12.9±8.5 ms) and SMVC-60 (60% =25.8±18.2 vs 9.96±4.2 ms), but returned to the baseline values when the contraction was interrupted. CONCLUSIONS: In patients with coronary artery disease and/or risk factors for coronary heart disease, low intensity isometric contraction, maintained over long periods of time, presents the same effect on the responses of HR, compared to a high intensity or maximal isometric contraction of briefly duration.

OBJETIVO: A meta deste artigo foi a de estudar as relações ente maus-tratos na infância e psicopatologia no adulto, como reflexo de uma disfunção do eixo hipotálamo-pituitária-adrenal. MÉTODO: Uma revisão seletiva da literatura relevante foi feita para identificar achados-chave e ilustrativos. RESULTADOS: Existe atualmente um volume significativo de achados científicos pré-clínicos e clínicos derivados de paradigmas experimentais, que demonstram que o estresse precoce está relacionado à função do eixo hipotálamo-pituitária-adrenal e a estados psicológicos no indivíduo adulto, e como esta relação pode ser modulada por outros fatores. DISCUSSÃO: O risco para o desenvolvimento de psicopatologia no adulto e disfunções do eixo hipotálamo-pituitária-adrenal está relacionado à complexa interação de múltiplos fatores vivenciais, assim como a genes que levam a uma susceptibilidade, que interagem com estes fatores. Embora as respostas agudas do eixo hipotálamo-pituitária-adrenal sejam geralmente adaptativas, as respostas excessivas podem levar a efeitos deletérios. O estresse precoce pode alterar a função do eixo hipotálamo-pituitária-adrenal assim como o comportamento, porém, o padrão da disfunção do eixo hipotálamo-pituitária-adrenal e a evolução psicológica na vida adulta refletem ambas as características do estressor e outros fatores modificadores. CONCLUSÃO: A pesquisa atual identificou múltiplos determinantes da disfunção do eixo hipotálamo-pituitária-adrenal encontrados em adultos com história de maus-tratos na infância ou outros estressores precoces. Trabalhos futuros são necessários para estabelecer se as anormalidades do eixo hipotálamo-pituitária-adrenal neste contexto podem ser usadas para o desenvolvimento de endofenótipos de risco para doenças físicas ou psiquiátricas.

OBJECTIVE: The aim of this paper was to examine the relationship between childhood maltreatment and adult psychopathology, as reflected in hypothalamic-pituitary-adrenal axis dysfunction. METHOD: A selective review of the relevant literature was undertaken in order to identify key and illustrative research findings. RESULTS: There is now a substantial body of preclinical and clinical evidence derived from a variety of experimental paradigms showing how early-life stress is related to hypothalamic-pituitary-adrenal axis function and psychological state in adulthood, and how that relationship can be modulated by other factors. DISCUSSION: The risk for adult psychopathology and hypothalamic-pituitary-adrenal axis dysfunction is related to a complex interaction among multiple experiential factors, as well as to susceptibility genes that interact with those factors. Although acute hypothalamic-pituitary-adrenal axis responses to stress are generally adaptive, excessive responses can lead to deleterious effects. Early-life stress alters hypothalamic-pituitary-adrenal axis function and behavior, but the pattern of hypothalamic-pituitary-adrenal dysfunction and psychological outcome in adulthood reflect both the characteristics of the stressor and other modifying factors. CONCLUSION: Research to date has identified multiple determinants of the hypothalamic-pituitary-adrenal axis dysfunction seen in adults with a history of childhood maltreatment or other early-life stress. Further work is needed to establish whether hypothalamic-pituitary-adrenal axis abnormalities in this context can be used to develop risk endophenotypes for psychiatric and physical illnesses.
