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. Clinical Trial registration: Brazilian Clinical Trials, number RBR-5qhmb5.

RESUMO: Embora neoplasmas em hamsters domésticos sejam comumente relatados, estudos retrospectivos abordando neoplasias espontâneas e os dados epidemiológicos associados são escassos. O presente estudo teve o objetivo de descrever os principais achados epidemiológicos e patológicos de 40 casos de tumores em hamsters domésticos diagnosticados em um laboratório de patologia veterinária do Sul do Brasil de 2002 a 2019. A principal espécie acometida foi o hamster chinês (Cricetulus griseus, 16/40), seguido por hamster anão russo siberiano (Phodopus sungorus, 11/40) e hamster sírio (Mesocricetus auratus, 4/40). As fêmeas corresponderam a 57,5% dos casos (23/40), enquanto os machos representaram 42,5% (17/40). Foram afetados roedores com uma faixa etária de 8 a 36 meses de idade, e uma mediana de 14 meses. Do total de casos, 24 foram exames anatomopatológicos (biopsias) e 16 casos foram examinados através de necropsia e, portanto, relacionados com a causa da morte dos animais. O sistema tegumentar foi o mais frequentemente acometido (60%; 24/40), seguido pelo trato reprodutivo (22,5%; 9/40), sistema hematopoietico (10%; 4/40), trato digestório (5%; 2/40) e sistema endócrino (2,5%; 1/40). A neoplasia mais frequentemente diagnosticada foi o carcinoma de células escamosas (35%; 14/40), localizado principalmente em região labionasal (50%; 7/14). Outros tumores incluíram fibrossarcoma (10%; 4/40), linfoma (10%; 4/40), adenoma cístico de glândula mamária (10%; 4/40), adenoma de glândula sudorípara (7,5%; 3/40), hemangiossarcoma (5%; 2/40), leiomiossarcoma (5%; 2/40) e tumor de células da granulosa (5%; 2/40). Os outros cinco casos remanescentes ocorreram individualmente e eram compostos por adenoma de glândula hepatoide, carcinoma sólido de tireoide, melanoma cutâneo, teratoma ovariano e tricoblastoma cutâneo. Neoplasmas foram identificados como importantes causas de morte ou razões para realização de biopsia em hamsters domésticos no Sul do Brasil.
ABSTRACT: Although neoplasms are commonly reported in domestic hamsters, retrospective studies approaching spontaneous tumors with data regarding epidemiological findings are scarce. The present study aimed to describe the epidemiological and pathological findings of 40 cases of tumors in domestic hamsters diagnosed in a veterinary pathology laboratory in Southern Brazil from 2002 to 2019. Chinese hamster (Cricetulus griseus) was the most commonly affected species (16/40), followed by Djungarian hamster (Phodopus sungorus, 11/40) and Syrian hamster (Mesocricetus auratus, 4/40). Among the cases, 57.5% were females (23/40), while 42.5% were males (17/40). The affected hamsters’ median age was of 14-months old, with an age range of 8- to 36-months old. Twenty-four cases were assessed as anatomopathological samples (biopsies), while 16 were composed of carcasses submitted to postmortem examination, and, therefore, the neoplasm was related to the cause of death. The integumentary system was frequently affected (60%, 24/40), followed by the female reproductive tract (22.5%, 9/40), hematopoietic system (10%, 4/40), digestive tract (5%, 2/40), and endocrine system (2.5%, 1/40). The most frequent neoplasm was squamous cell carcinoma (35%, 14/40), mostly on the lip/nasal region (50%, 7/14). Other tumors included fibrosarcoma (10%, 4/40), lymphoma (10%, 4/40), mammary cystadenoma (10%, 4/40), apocrine sweat gland adenoma (7.5%, 3/40), hemangiosarcoma (5%, 2/40), leiomyosarcoma (5%, 2/40), and granulosa ovarian cell tumor (5%, 2/40). The five remaining cases occurred individually and were composed of hepatoid gland adenoma, solid thyroid carcinoma, cutaneous melanoma, ovarian teratoma, and cutaneous trichoblastoma. Neoplasms were identified as an important cause of death and major reason to perform biopsy in domestic hamsters in Southern Brazil.

RESUMO O objetivo deste trabalho foi avaliar o efeito de diferentes tempos de desidratação do descarte de tomate (0, 4, 24, 60 e 96 horas) adicionado nas silagens de casca de mandioca sobre a densidade, perdas fermentativas, recuperação de matéria seca, composição química e qualidade sensorial. O material foi ensilado por 60 dias em silos de cloreto de polivinila (PVC). Houve redução linear de 0,406 kg ton-1 de matéria fresca na produção de efluente nas silagens. Máxima perda de matéria seca (MS) (p <0,01) de 7,00% foi encontrada com 8,10 h de desidratação do descarte de tomate. Houve comportamento quadrático (p <0,01) para os teores de proteína bruta (PB) e carboidratos não fibrosos (CNF), com mínimo de 9% de PB e máximo de 66,0% de CNF com 3,53 e 7,35 h de desidratação do descarte de tomate, respectivamente. A classificação "satisfatória" foi observada nas silagens com 4, 24 e 96 h de desidratação do descarte de tomate na avaliação sensorial das características associadas à conservação. A casca da mandioca ensilada com descarte de tomate submetido ao tempo de desidratação de 7,35 horas é suficiente para promover um conteúdo adequado de carboidratos não fibrosos, associado a menores perdas no processo fermentativo.
ABSTRACT The aim of this study was to evaluate the effect of different dehydration times of the tomato waste (0, 4, 24, 60 and 96 hours) added in the cassava peel silages on the density, fermentative losses, dry matter recovery, chemical composition, and sensorial quality. The material was ensiled for 60 days in polyvinyl chloride (PVC) silos. There was a linear reduction of 0.406 kg tonne-1 of fresh matter in the effluent production in the silages. A maximum dry matter (DM) loss (p<0.01) of 7.00% was found with 8.10 h of dehydration of the tomato wastes. There was a quadratic behavior (p<0.01) for crude protein (CP) and non-fibrous carbohydrates (NFC), with minimum content of 9% CP and maximum content of 66.0% NFC with 3.53 h and 7.35 h of dehydration of the tomato wastes, respectively. The "satisfactory" classification was observed to the silages with 4, 24 and 96 h of dehydration of tomato waste in the sensory evaluation of the characteristics associated with the conservation. Cassava peel ensiling with tomato waste submitted to dehydration time of 7.35 hours is enough to promote an adequate non-fibrous carbohydrates content, associated with lower losses in the fermentation process.

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.

<p>Major ionic constituents (Cl<sup>–</sup>, Na<sup>+</sup>, K<sup>+</sup>, Mg<sup>2+</sup>, Ca<sup>2+</sup>, NH<sub>4</sub><sup>+</sup>, NO<sub>3</sub><sup>–</sup>, SO<sub>4</sub><sup>2–</sup>) and dissolved organic nitrogen were determined, from September 2009 to January 2010, in bulk atmospheric deposition in the lower course of Cachoeira River, southern Bahia, Brazil, where studies on this theme are still absent. The high fluxes of Na+, Mg2+ and Cl– observed in the innermost sampling site evidence the continuity of marine influence in the atmosphere of the city of Itabuna. Concentrations of H<sup>+</sup>, Ca<sup>2+</sup>, SO<sub>4</sub><sup>2–</sup> and NO<sub>3</sub><sup>–</sup> denoted non-marine anthropogenic sources. The contributions of dissolved organic and inorganic nitrogen were different between the evaluated sites. This region is still subject to little impact by anthropogenic emissions compared to other urban areas in Brazil, according to estimates of atmospheric fluxes of SO<sub>4</sub><sup>2–</sup>, NO<sub>3</sub><sup>–</sup> and NH<sub>4</sub><sup>+</sup>.</p>

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

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: 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.

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.
