BACKGROUND In Brazil, the yellow fever virus (YFV) is maintained in a sylvatic cycle involving wild mosquitoes and non-human primates (NHPs). The virus is endemic to the Amazon region; however, waves of epidemic expansion reaching other Brazilian states sporadically occur, eventually causing spillovers to humans. OBJECTIVES To report a surveillance effort that led to the first confirmation of YFV in NHPs in the state of Minas Gerais (MG), Southeast region, in 2021. METHODS A surveillance network was created, encompassing the technology of smartphone applications and coordinated actions of several research institutions and health services to monitor and investigate NHP epizootics. FINDINGS When alerts were spread through the network, samples from NHPs were collected and YFV infection confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and genome sequencing at an interval of only 10 days. Near-complete genomes were generated using the Nanopore MinION sequencer. Phylogenetic analysis indicated that viral genomes were related to the South American genotype I, clustering with a genome detected in the Amazon region (state of Pará) in 2017, named YFVPA/MG sub-lineage. Fast YFV confirmation potentialised vaccination campaigns. MAIN CONCLUSIONS A new YFV introduction was detected in MG 6 years after the beginning of the major outbreak reported in the state (2015-2018). The YFV strain was not related to the sub-lineages previously reported in MG. No human cases have been reported, suggesting the importance of coordinated surveillance of NHPs using available technologies and supporting laboratories to ensure a quick response and implementation of contingency measures to avoid YFV spillover to humans.

Abstract: En Pt

Objective: To analyze the frequency distribution of condom use according to vulnerability factors for sexually transmitted infections in quilombola communities in Sergipe, Brazil. Methods: Descriptive cross-sectional study carried out between 2016-2017. A structured questionnaire with sociodemographic and behavioral issues was used; and rapid HIV and syphilis tests were performed. Comparisons between categorical variables were performed using Fisher's exact test.  Results: Among the 367 individuals from 14 communities, the majority were of low education (72.8%), without work (59.7%) and had a fixed sexual partner (90.7%). Lack of access to inputs and prevention information made up the programmatic vulnerability of individuals. There was a higher proportion of inconsistent condom use with a steady partner (90.1%) in individuals who reported lack of access to information (p=0.001) and inconsistent use with an occasional partner (p<0.001). Conclusion: The frequency of condom use with a steady partner was significantly proportional to the use with a casual partner and access to preventive information.

Objetivo: Analisar a frequência do uso de preservativos segundo fatores de vulnerabilidade para infecções sexualmente transmissíveis em comunidades quilombolas de Sergipe, Brasil. Métodos: Estudo transversal descritivo, realizado entre 2016 e 2017. Utilizou-se questionário estruturado, com questões sociodemográficas e comportamentais; foram realizados testes rápidos de HIV e sífilis. Comparações entre variáveis categóricas foram realizadas pelo teste exato de Fisher. Resultados: Entre os 367 indivíduos de 14 comunidades, a maioria apresentava baixa escolaridade (72,8%), encontrava-se sem trabalho (59,7%) e possuía parceiro sexual fixo (90,7%). Falta de acesso a insumos e informações de prevenção compuseram a vulnerabilidade programática dos indivíduos. Houve maior proporção de uso inconsistente do preservativo com parceiro fixo (90,1%), em indivíduos que relataram falta de acesso à informação (p=0,001) e uso inconsistente com parceiro eventual (p<0,001). Conclusão: A frequência de uso do preservativo com parceiro fixo foi significativamente proporcional ao uso com parceiro eventual e ao acesso a informação preventiva.

Abstract Objective To analyze frequency of condom use according to vulnerability factors for sexually transmitted infections in quilombola communities in Sergipe state, Brazil. Methods This was a descriptive cross-sectional study carried out in 2016-2017. A structured questionnaire with sociodemographic and behavioral questions was used; rapid HIV and syphilis tests were performed. Comparisons between categorical variables were performed using Fisher’s exact test. Results Among the 367 individuals from 14 communities, the majority had low levels of education (72.8%), were not working (59.7%) and had a stable sex partner (90.7%). Lack of access to prevention supplies and information accounted for respondent programmatic vulnerability. There was a higher proportion of inconsistent condom use with a stable partner (90.1%) among individuals who reported lack of access to information (p=0.001) and inconsistent use with a casual partner (p<0.001). Conclusion Frequency of condom use with a stable partner was significantly proportional to condom use with a casual partner and access to information on prevention.

Abstract: En | Text: En | PDF: En

Unforeseen Plasmodium infections in the Atlantic Forest of Brazilian Extra-Amazonian region could jeopardise malaria elimination. A human malaria case was registered in Três Forquilhas, in the Atlantic Forest biome of Rio Grande do Sul, after a 45 years’ time-lapsed without any malaria autochthonous notification in this southern Brazilian state. This finding represents the expansion of the malaria distribution areas in Brazil and the southernmost human malaria case record in South America in this decade. The coexistence of the bromeliad-breeding vector Anopheles (Kerteszia) cruzii and non-human primates in the Atlantic Forest regularly visited by the patient claimed for the zoonotic origin of this infection. The reemergence of Atlantic Forest human malaria in Rio Grande do Sul was also discussed.

Resumo A proposta foi avaliar os efeitos produzidos pela Lei nº 13.043/2014 no mercado de empréstimo de ações que impossibilitou, legalmente, a estratégia de “barriga de aluguel” por agentes desonerados. A hipótese é que a estratégia de arbitragem tributária adotada pelos fundos restringia a venda a descoberto. Utilizaram-se dados do mercado de empréstimo e à vista, de 2014 e 2015, para estimar o efeito da lei pelo Método de Diferenças em Diferenças via regressão de Mínimos Quadrados Ordinários Robusto. Os efeitos-lei médios foram significativos e condizente com a teoria registrando redução das taxas e aumento de volumes de empréstimos de ações.

Abstract The Law no. 13.043/2014 made impossible the “barriga de aluguel”strategy on the stock Market. The hypothesis is that the funds’s tax arbitrage strategy due the condition relief’s tax was a short selling’s restriction. We used the market data from the companies listed in B3 of 2014 and 2015 to estimate the law’s mean-effect by Differences in Differences with robust least squares regression. The regressions’s results suggest that the average law-effects were significant and consistent with the theory due the reduction in lendingrates reflected in the increase in trading volumes on the stock lending market.

ABSTRACT The potential mobility of Cd, Cr, Cu, Ni, Pb and Zn in soils severely impacted by inadequate storage of industrial wastes in Rio de Janeiro State (Brazil) was evaluated by applying the Toxicity Characteristic Leaching Procedure (TCLP). This procedure allowed the estimation of toxicity risks for Cd, Cr and Pb. In a contamination hotspot within the study area, the following order of metal concentrations was observed: Pb > Zn > Cu > Ni > Cd > Cr, with significantly higher values than observed for a control site. Decades of soil exposure to wastes implied TCLP results for Pb above 300 mg/L in this hotspot, which exceed the TCLP regulatory threshold in two orders of magnitude, while Cd (up to 0.8 mg/L) and Cr (up to 0.3 mg/L) results were below the respective TCLP thresholds. Surface soil profile analysis (0-30 cm depth) indicates that Pb vertical migration occurs in the hotspot. TCLP concentrations of Pb were up to four orders of magnitude higher than the groundwater quality threshold preconized by Brazilian regulations for this metal (0.01 mg/L), suggesting that downward dispersion of large loadings of anthropogenic Pb is a major concern.

RESUMEN La movilidad potencial de Cd, Cr, Cu, Ni, Pb y Zn en suelos gravemente afectados por el almacenamiento inadecuado de desechos industriales en el estado de Río de Janeiro, Brasil, se evaluó mediante la aplicación del procedimiento de lixiviación con características de toxicidad (TCLP, por sus siglas en inglés). Este procedimiento permitió la estimación de riesgos de toxicidad para Cd, Cr y Pb. En una zona de alta contaminación dentro del área de estudio, se observó el siguiente orden de concentraciones de metales: Pb > Zn > Cu > Ni > Cd > Cr, con valores significativamente más altos que los observados para un sitio de control. Décadas de exposición del suelo a desechos implicaron resultados de TCLP para Pb por encima de 300 mg/L en esta zona, los cuales exceden el umbral regulatorio de TCLP en dos órdenes de magnitud, mientras que los valores de Cd (hasta 0.8 mg/L) y Cr (hasta 0.3 mg/L) estuvieron por debajo de los umbrales de TCLP respectivos. El análisis del perfil del suelo superficial (0-30 cm de profundidad) indica que la migración vertical de Pb se produce en la zona de alta contaminación. Las concentraciones de Pb obtenidas con el TCLP fueron hasta cuatro órdenes de magnitud más altas que el umbral de calidad del agua subterránea recomendado por las regulaciones brasileñas para este metal (0.01 mg/L), lo que sugiere que la dispersión descendente de grandes cargas de Pb antrópico es un problema importante.

RESUMEN Las plantas medicinales tienen un gran potencial en la producción de fitocompuestos, estos son derivados para fines diversos, principalmente en la industria de medicamentos y cosméticos. El objetivo de este estudio fue evaluar el aceite esencial de Lippia alba, cultivada con proporciones de amonio (NH4+) y nitrato (NO3 -) en entornos de luz. Las plantas fueron sometidas a cinco proporciones de NH4 +: NO3 -, adicionados por soluciones nutritivas, y cuatro ambientes de luz (mallas roja, aluminet y negra, y solar completo). El diseño experimental fue completamente al azar con la interacción 5x4, con 5 repeticiones por tratamiento, para un total de 100 unidades experimentales. Las plántulas fueron transplantadas a macetas de plástico 6 dm3 de capacidad, conteniendo una mezcla de arena lavada + vermiculita en relación 2:1. Después de 120 días de la aplicación de los tratamientos, los parámetros evaluados fueron rendimiento, contenido de humedad y la composición del aceite esencial. La extracción se realizó a través de hidrodestilacion por arrastre de vapor, para un período de 2 horas. Se encontraron nueve compuestos en los aceites esenciales, el geranial y neral representaron el 90% de la mezcla, la carvona sólo se encontró en el tratamiento con plantas cultivadas bajo malla roja y con la relación de 50:50 de amonio y nitrato.

ABSTRACT Medicinal plants have great potential for the production of phytocompounds, which are used for various purposes, mainly in drugs and cosmetics. The aim of this study was to evaluate the essential oil from Lippia alba cultivated with ammonium (NH4+) and nitrate (NO3 -) under light environments. The plants were subjected to five ratios of NH4 +: NO3 - with nutritious solutions and four light environments (red, aluminet and black mesh, and full sun). The experiment design was entirely randomized with a 5x4 interaction and five repetitions per treatment, totaling 100 experiment units. The seedlings were transplanted to 6 dm3 plastic pots containing a mixture of washed sand + vermiculite at a ratio of 2:1. At 120 days after application of the treatments, the following parameters were evaluated: yield, content and composition of essential oil. The extraction was performed with the hydrodistillation method using drag of steam for a period of 2 hours. Nine compounds were found in the essential oil, of which neral and geranial represented 90% of the blend. Carvone was only found in the treatment with plants grown under the red mesh and with the 50:50 ratio of ammonium and nitrate.

Abstract INTRODUCTION: We assessed the clinical-epidemiological profile of acquired immune deficiency syndrome (AIDS) patients in the Santos region (São Paulo state) with the highest AIDS prevalence in Brazil. METHODS Information was extracted from records of 409 AIDS-infected patients hospitalized between 2011 and 2016. RESULTS: Human immunodeficiency virus (HIV) was diagnosed in 24.7% of patients during admission, and 39.6% of already diagnosed patients received highly active antiretroviral therapy (HAART) irregularly. The mortality rate was 19.1%, and the main secondary manifestations were neurotoxoplasmosis and tuberculosis. CONCLUSIONS: AIDS patients in the Santos region had high rates of late diagnosis and low treatment adherence.

Abstract OBJECTIVE to find the social representations of female students about female condoms. Methodology: exploratory and descriptive study, with qualitative approach, based on the Theory of Social Representations. METHOD 94 students from high school students, technical courses, and adult education participated, all from public schools from a municipality in the countryside of Bahia/Brazil, and responded to the test of free word association. The evocations were submitted to the softwares EVOC and IRAMUTEQ. RESULTS students recognize that the female condom is a technology that provides autonomy, protects against sexually transmitted infections, and prevents pregnancy. In contrast, they reported that their reasons for not using the method are finding it uncomfortable and strange. FINAL CONSIDERATIONS Social representations point to the need for strategies that promote information exchange and stimulate practical knowledge about the female condom among public school students.

RESUMO Objetivo Avaliar a relação de marcadores de estresse oxidativo com a infecção pelo papilomavírus humano e as lesões precursoras do câncer cervical. Métodos Foram incluídas mulheres ribeirinhas da Amazônia (a saber: 126 do município de Itaituba, 68 de Limoeiro do Ajuru e 43 de Bragança), todas do Estado do Pará, de 14 a 60 anos. Foram realizados testes Papanicolau e de reação em cadeia de polimerase para a detecção de DNA do papilomavírus humano. Coleta de amostras de sangue foi realizada para a avaliação do malondialdeído e a determinação da glutationa total e oxidada. Resultados As concentrações oxidativas do malondialdeído e os teores de glutationa total e oxidada não apresentaram diferença significativa (p>0,05) nas mulheres com e sem lesão intraepitelial escamosa de baixo grau, em todas as comunidades pesquisadas. Mulheres com papilomavírus humano em Itaituba apresentaram níveis de malondialdeído (8,02nmols/mL) quase cinco vezes maior quando relacionadas àquelas sem o HPV (1,70nmols/mL), com diferença estatística significativa (p<0,05). As outras comunidades não mostraram diferença estatística significativa entre as concentrações de malondialdeído nas mulheres com e sem papilomavírus humano (p>0,05). Os teores de glutationa total mostraram diferença significativa (p<0,05) somente em Bragança naquelas com (8,20µg/mL) e sem a infecção pelo papilomavírus humano (1,47µg/mL). Conclusão Houve associação significativa da resposta oxidativa do malondialdeído e da glutationa total com a infecção pelo papilomavírus humano, porém não houve diferença quando associada à lesão escamosa, sugerindo que o estresse oxidativo isoladamente não explica a relação com a carcinogênese do colo uterino, que deve ser influenciada ainda por outros fatores.

ABSTRACT Objective To investigate the relation between oxidative stress markers, human papillomavirus infection and cervical cancer precursor lesions. Methods The study comprised women aged 14 to 60 years living in communities located by Amazon rivers in the state of Pará (Itaituba, Limoeiro do Ajuru and Bragança, 126, 68 and 43 women respectively). Papanicolau smears and polymerase chain reaction tests for human papillomavirus DNA detection were performed. Blood samples were collected to test malondialdehyde, total and oxidized glutathione levels. Results Malondialdehyde, total and oxidized glutathione concentrations did not differ significantly (p>0.05) between women with and without low-grade squamous intraepithelial lesions across communities. Malondialdehyde levels (8.02nmols/mL) were almost five times higher in human papillomavirus-positive compared to human papillomavirus-negative women (1.70nmols/mL) living in Itaituba (statistically significant difference; p<0.05). Malondialdehyde levels did not differ significantly (p>0.05) between human papillomavirus-positive and human papillomavirus-negative women living in remaining communities. Significant (p<0.05) differences in total glutathione levels between human papillomavirus-positive and human papillomavirus-negative women (8.20μg/mL and 1.47μg/mL, respectively) were limited to those living in Bragança. Conclusion Malondialdehyde and total glutathione levels were significantly associated with human papillomavirus infection. However, lack of similar associations with squamous lesions suggest oxidative stress alone does not explain correlations with cervical carcinogenesis. Other factors may therefore be involved.

RESUMO Objetivo O objetivo do estudo foi traduzir e adaptar culturalmente para a Língua Portuguesa Brasileira o instrumento TELEGRAM e avaliar sua aplicabilidade em adultos com deficiência auditiva usuários de Aparelho de Amplificação Sonora Individual. Método Foram realizadas a tradução do TELEGRAM para o idioma Português, a revisão das equivalências gramatical e idiomática (traduções reversas) e as adaptações linguística e cultural. Após a tradução, o TELEGRAM foi aplicado em 20 indivíduos adultos com deficiência auditiva. Resultados Foi realizada análise descritiva dos resultados. Após a equivalência gramatical e idiomática foi sugerida substituição de um termo/item, tendo sido o mesmo modificado e compatibilizado ao contexto brasileiro. De modo geral, as perguntas do questionário foram consideradas de fácil entendimento. Dentre as categorias avaliadas, os indivíduos com deficiência auditiva apresentaram maior dificuldade quanto ao uso do telefone e em atividades como participar de eventos em igrejas, festas, ou seja, em situações de ruído, distância e reverberação. Conclusão O TELEGRAM traduzido para a Língua Portuguesa Brasileira mostrou ser uma ferramenta de fácil aplicação na população estudada e efetivo para avaliar quais são as principais situações em que indivíduos com deficiência auditiva apresentam maior dificuldade de comunicação, reforçando a importância da reabilitação auditiva e das tecnologias assistivas para minimizar essas dificuldades.

ABSTRACT Purpose The objective of the study was to translate and culturally adapt to Portuguese the TELEGRAM instrument and to evaluate its effectiveness in adults with hearing impairment using hearing aids. Methods The TELEGRAM was translated into the Portuguese language, reviewed for grammatical and idiomatic equivalences (reverse translations) and linguistic and cultural adaptations. After translation, the TELEGRAM was applied to 20 individuals with hearing impairment. Results A descriptive analysis of the results was performed. After the grammatical and idiomatic equivalence, the replacement of one term/item was suggested, which was modified and adapted to the Brazilian context. In general, the questions of the instrument were considered easy to understand. Among the categories assessed, individuals with hearing loss had greater difficulty using the telephone and in activities such as attending church gatherings, parties, or in situations of noisy environments, distance and reverberation. Conclusion The TELEGRAM translated into Brazilian Portuguese proved to be an easily applicable tool in population studies and effective to assess which are the main situations where individuals with hearing impairment have greater difficulty in communication, reinforcing the importance of hearing rehabilitation and assistive technology to minimize these difficulties.

RESUMO O objetivo deste trabalho foi testar a aplicabilidade das redes neurais artificiais na estimação da altura em testes clonais e de progênies de eucalipto. Foram utilizados 8.329 dados de teste clonal, coletados em seis idades, divididos em 6 blocos e 5 repetições, e 36.793 dados para o teste de progênie, coletados em 5 idades e divididos em 10 blocos e 5 repetições. As variáveis categóricas de entrada foram a idade, o genótipo e o bloco. O diâmetro (dap) foi utilizado com variável de entrada contínua. Para definição dos dados para treinamento das redes foram utilizadas duas sub-amostras: a sub-amostra 1, composta pela primeira árvore de cada bloco e a sub-amostra 2, uma árvore foi selecionada aleatoriamente dentro de cada bloco. Essa seleção foi feita para os testes clonal e de progênies. Os dados selecionados foram separados em 70% para treinamento e 30% para a validação. As demais árvores, que não faziam parte das duas sub-amostras, foram utilizadas para a generalização. Para cada idade e tratamento foi calculado o teste kolmogorov - Smirnov (K-S) afim de verificar a normalidade dos resíduos. Os resultados demonstram que as redes podem ser usadas na estimação da altura das árvores dos diferentes genótipos presentes nos testes clonais e de progênies, sem perda da exatidão e significativa redução de custo de medição dos experimentos.

ABSTRACT The goal of this study was to test the applicability of artificial neural networks for estimating tree heights in clonal tests and progenies. We used data from 8,329 clonal tests collected for six age groups, divided into six blocks and five repetitions. For the progeny tests, we used 36,793 data points, collected at age 5 and divided into ten blocks and five repetitions. The categorical input variables considered were age, treatment, and block. The diameter (dap) was used with continuous input variables. For training the networks, we used two samples. Sub-sample 1 was composed of the first tree of each block. In sub-sample 2, the tree was selected randomly within each block. This selection was made in both tests. The selected data were separated, with 70% used for training and 30% used for validation. The other unselected trees were used for generalization. For each age and treatment, we used the Kolmogorov-Smirnov (KS) test to verify the normality of the errors. The results show that ANNs can be used to estimate the heights of trees subjected to various experimental plot treatments, with no loss of accuracy or estimation precision.

Abstract: En | Text: En | PDF: En

The present study tested the hypothesis that species richness and composition of epiphytic microlichens can be used to support the phytosociological differentiation between Caatinga and Brejos de Altitude, as exemplified by the Muralha Reserve (Caatinga) and the Parque Estadual Mata do Pau Ferro (Brejo de Altitude), in the state of Paraíba, Brazil. A total of 755 lichen samples were collected, comprising 18 families, 42 genera and 111 species of epiphytic, corticolous microlichens. Overall species richness was higher in the Caatinga, with 67 species, compared to the Brejo, with 46 species. Species richness per sample was significantly higher in the Caatinga compared to the Brejo. Taxonomic composition also differed significantly between the two areas, with Arthoniaceae, Caliciaceae, Chrysothrichaceae, Graphidaceae (particularly Graphis), Lecanoraceae, Mycoporaceae, Pertusariaceae, and Trypetheliaceae being dominant in, or exclusive to, the Caatinga, whereas Coenogoniaceae, Graphidaceae (Diorygma, Fissurina, Myriotrema, Ocellularia, Phaeographis, Sarcographa), Malmideaceae, Porinaceae and Strigulaceae were dominant in, or exclusive to, the Brejo. Five new species were discovered as result of this study. This is the first study to quantitatively compare richness and community patterns of epiphytic microlichens between two major biomes in Northeastern Brazil, and the first detailed lichen study in the state of Paraíba.
