The formation of solid waste is a global challenge regarding environmental preservation. Due to the lifestyle of modern society, which aims to improve practicality, new products are constantly being released in the market and increasing the formation of waste. The decomposition of waste from various origins produces a dark liquid named leachate, which presents high rates of organic and inorganic compounds. The objective of this study was to assess the concentration of potentially toxic metals in the leachate collected from the Aurá dump. The concentrations of Cd, Cu, Cr, Mn, Ni, Pb, and Zn were evaluated in leachate samples collected in a period of a year, covering two typical seasonal periods of the Amazon region with more and less rainfall. The leachate samples collected in the Aurá dump were determined in the Toxicology Laboratory of Instituto Evandro Chagas (IEC), by means of Plasma/Inductively Coupled Optical Emission Spectrometry (ICP-OES). The Cr, Mn, and Pb metals analyzed in the slurry samples are in a concentration above the maximum limits specified by CONAMA Resolution No. 430/2011, causing significant environmental concerns.

Resumo: O estado de Goiás, no Brasil central, é coberto principalmente pelo domínio do Cerrado, com a Mata Atlântica do Alto Paraná ocupando sua porção centro-sul. Goiás é uma das 20 unidades federativas brasileiras que ainda não possui uma lista de espécies de mamíferos. Neste estudo, apresentamos a primeira lista de mamíferos para o estado. Registramos as espécies de mamíferos com base principalmente na análise de espécimes depositados em coleções científicas, bem como na literatura apresentando material testemunho associado. Listamos 191 espécies pertencentes a 125 gêneros, 31 famílias e 10 ordens, as quais representam 25,2% das espécies de mamíferos que ocorrem no Brasil. As ordens mais especiosas foram Chiroptera (90 spp.), seguida pelas ordens Rodentia (43 spp.), Carnivora (19 spp.) e Didelphimorphia (17 spp.), com as demais ordens respondendo por uma porção menor da diversidade: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.) e Perissodactyla (1 sp.). Um total de 28 espécies (14,7%), principalmente representadas por mamíferos de médio e grande porte, estão ameaçadas nacionalmente e 12 (6,3%) encontram-se globalmente ameaçadas. Nossos resultados indicaram grandes porções do estado ainda não devidamente pesquisadas em relação aos seus mamíferos, com informações escassas e fragmentadas, principalmente no que diz respeito à sua porção noroeste. Discutimos a riqueza de espécies, a distribuição e o estado de conservação dos mamíferos do estado de Goiás nos cenários nacional e regional. Ressaltamos a importância da realização de inventários que utilizem técnicas complementares de amostragem, incluindo a coleta de material testemunho, proporcionando a obtenção de dados cariotípicos, moleculares, morfológicos, parasitológicos e ecológicos. Estas informações são a base de estudos integrativos, os quais aumentam nossa compreensão a respeito da riqueza e diversidade atual dos mamíferos. O conhecimento a respeito da distribuição da riqueza de espécies em Goiás é essencial para embasar estratégias de conservação, tão necessárias em áreas que vem sofrendo com a perda e fragmentação de seus hábitats naturais, como a porção centro-sul do estado.

Abstract: The state of Goiás, in central Brazil, is covered mainly by the Cerrado domain, with the Alto Paraná Atlantic Forest occupying its central-southern portion. Goiás is one of the 20 Brazilian federative units without a mammal checklist. In this study, we provide the first checklist of mammals from Goiás state. We recorded mammal species based primarily on the analysis of specimens housed in scientific collections as well as on literature with associated voucher material. We listed 191 mammalian species belonging to 125 genera, 31 families and 10 orders, which represents 25.2% of the mammal species occurring in Brazil. The most speciose orders were Chiroptera (90 spp.), followed by Rodentia (43 spp.), Carnivora (19 spp.) and Didelphimorphia (17 spp.). The following orders accounted for a smaller portion of the state diversity: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.), and Perissodactyla (1 sp.). A total of 28 species (14.7%), mainly represented by medium and large-sized mammals, are nationally threatened while 12 (6.3%) are globally threatened. Our results indicate great portions of the state lacking a proper survey of mammals, especially the northwestern portion. We discuss species richness, distribution and conservation status of the mammals of Goiás state in national and regional scenarios. We highlight the need for mammal inventories based on complementary survey techniques with the collection of vouchers in order to provide karyologic, molecular, morphologic, parasitologic, and ecological data. These informations are the basis for integrative studies that lead to the understanding of current mammalian richness and diversity. Indeed, knowledge on species richness distribution in the state will guide conservation strategies, especially in areas undergoing habitat loss and fragmentation, such as the central-southern portion of Goiás.

Abstract: En | Text: En | PDF: En

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

ABSTRACT Objective: Assess adherence to school food offered by the School Food Program (Programa Nacional de Alimentação Escolar - PNAE) and the associated factors among Brazilian adolescents. Methods: Cross-sectional study with data from the Study of Cardiovascular Risks in Adolescents conducted in 2013-2014, with 58,707 adolescents aged 12 to 17 years-old who attended public schools. Logistic regression models were stratified by sex and the significance level of 5% was adopted for all analyses. Results: There was low adherence to school meals (17.2%). The chance of regular consumption of school meals was higher among male adolescents belonging to the medium (p<0.05) and the low (p<0.05) socioeconomic score categories. For females, the chance of regular consumption of food offered at school was higher among black-skinned, brown-skinned, indigenous-skinned or yellow-skinned adolescents (p<0.05), aged 16 and 17 (p<0.05), who worked (p<0.001) and belonged to the medium (p<0.05) and low (p<0.05) socioeconomic score categories. The regular purchase of food in school cafeterias reduced the chance of regular consumption of school meals for males (p<0.001) and females (p<0.001). Conclusions: Adherence to the food offered by the PNAE is far from ideal, and it is important to create public policies that encourage the consumption of school meals and improve adherence. In addition, the strengthening and drafting of regulations aimed at the sale of food in the interior and surrounding schools' areas is necessary.

RESUMEN Objetivo: Evaluar la adherencia a la comida escolar ofrecida por el Programa Nacional de Alimentación Escolar y los factores asociados entre los adolescentes brasileños. Métodos: Estudio transversal con datos del Estudio de Riesgos Cardiovasculares en Adolescentes realizado en 2013-2014, con 58.707 adolescentes de 12 a 17 años que asistieron a escuelas públicas. Los modelos de regresión logística se realizaron estratificados por sexo, y se aplicó el nivel de significancia del 5% para todos los análisis. Resultados: Hubo baja adherencia a las comidas escolares (17,2%). La posibilidad de consumo regular de comidas escolares fue mayor entre los adolescentes varones pertenecientes a las categorías de puntaje socioeconómico medio (p<0,05) y bajo (p<0,05). Para las mujeres, la probabilidad de consumo regular de alimentos ofrecidos en la escuela fue mayor entre las adolescentes de piel negra, marrón, indígena o amarilla (p<0,05), de 16 y 17 años (p<0,05), quién trabaja (p<0,001) y pertenece a las categorías de puntaje socioeconómico medio (p<0,05) y bajo (p<0,05). La compra regular de alimentos en las cafeterías escolares redujo la posibilidad de consumo regular de comidas escolares para hombres (p<0,001) y mujeres (p<0,001). Conclusiones: La adhesión a los alimentos ofrecidos por el PNAE está lejos de ser ideal, y es importante crear políticas públicas que fomenten el consumo de comidas escolares, mejoren su adherencia, además de ayudar en el fortalecimiento y la redacción de regulaciones dirigidas a la venta de alimentos en el interior y las áreas de las escuelas circundantes.

ABSTRACT Objective Climacterium is associated with elevated leptin levels and increased risk of cardiovascular disorders. Conflicting data diverge on whether high leptin levels in climacterium reflect increasing adipose mass or, at least partially, age-related hormonal changes. This study addresses this issue in women from a Brazilian state with a low human development index. Subjects and methods A case-control study was conducted, enrolling 136 women from the state of Maranhão, 52 (38.2%) climacteric and 84 (61.8%) non-climacteric. Biometric, biochemical, hormonal and immunological parameters were analyzed. Results Climacteric women showed a moderately increased waist/hip ratio (0.894 versus 0.834, p < 0.05), sustained body mass index (27.46 versus 28.68, p > 0.05) increased leptin levels (9.59 versus 7.13, p < 0.05) and no evidence of metabolic syndrome. No other parameters were altered. The climacteric cohort didn’t show significant body fat gains but displayed a typical age-related redistribution of adipose tissue. Even so, leptin levels were significantly elevated compared with non-climacteric women. Conclusions Altogether, these data support the hypothesis that leptin is elevated, at least partially, as a function of age and climacterium and is not necessarily correlated with metabolic dysfunction and systemic inflammation. Further studies are needed to evaluate the impact of higher leptin levels on postmenopausal women. Arch Endocrinol Metab. 2020;64(3):276-81

RESUMO O carcinoma ameloblástico (CA) é um tumor odontogênico raro que representa o equivalente maligno de um ameloblastoma. Existem poucos casos de CA na literatura em inglês: nos últimos 10 anos, foram relatados apenas 16 casos surgidos de ameloblastomas preexistentes. Múltiplas recorrências locais desse tumor precedem essa transformação. Neste relato, descrevemos um caso de CA em região posterior de maxila em uma mulher de 42 anos de idade, submetida à ressecção cirúrgica. Em um período de quatro anos, ocorreram três recidivas do ameloblastoma. Exames de imagem exibiram uma massa radiodensa com destruição da cortical óssea e invasão do seio maxilar. A análise histológica revelou ilhas e ninhos característicos de transformação maligna epitelial, atipias, pleomorfismo celular, hipercromatismo nuclear, necrose e desmoplasia. O CA representa um raro e desafiador diagnóstico histológico. O acesso cirúrgico com ampliação das margens de tecido duro e mole é essencial para o impacto na sobrevida do paciente. A descrição de novos casos pode revelar, por meio do tratamento e do acompanhamento clínico, características que ajudem a entender melhor o comportamento do CA.

ABSTRACT Ameloblastic carcinoma (AC) is a rare odontogenic tumor that represents the malignant counterpart of an ameloblastoma. There are few cases of AC in the English-language literature, with only 16 cases arising from preexisting ameloblastomas reported in the last 10 years. Multiple local recurrences of ameloblastomas precede this transformation. In the current report, we describe a case of AC at the posterior maxilla in a 42-year-old female submitted to surgical resection, with three recurrences of ameloblastoma in a period of four years. Imaging exams showed a radiodense mass with cortical bone disruption and maxillary sinus invasion. Histologic analysis demonstrated features of islands and nests of malignant epithelium transformation, atypia, pleomorphic cells, nuclear hyperchromatism, necrosis and desmoplasia. AC represents a rare and challenging histologic diagnosis. Surgical access with adequate hard and soft tissue margins is essential for influencing survival. The description of new cases may reveal, through of treatment and clinical follow-up, characteristics that allow us better understanding of AC behavior.

Hay pocos casos de CA en la literatura en lengua inglesa: en los últimos 10 años, sólo se reportaron 16 casos originados de ameloblastomas previos. Múltiples recidivas locales de este tumor preceden esa transformación. En este reporte, describimos un caso de CA en región posterior de maxila en una mujer de 42 años de edad, sometida a resección quirúrgica.

El análisis histológico ha revelado islas y nidos característicos de transformación epitelial maligna, atipias, pleomorfismo celular, hipercromatismo nuclear, necrosis y desmoplasia. El diagnóstico histológico del CA representa un raro desafío. El abordaje quirúrgico con ampliación de los márgenes de tejido duro y blando es esencial en la sobrevida del paciente. La descripción de nuevos casos puede revelar, mediante tratamiento y acompañamiento clínico, características que ayuden a comprender mejor el comportamiento del CA.

ABSTRACT The startup operation of distillation columns is one of the most complex steps performed in the industry. This complexity becomes even greater for thermally coupled extractive distillation systems. Thermally coupled configurations are commonly used in order to minimize the excessive amount of energy required to perform distillation. In view of this, this study aimed to develop a startup procedure for the thermally coupled extractive distillation system to obtain anhydrous ethanol by simulation using the computational package Aspen Plus Dynamics. From the startup procedure developed, the complex dynamic behavior of the system under study was analyzed (strong interaction between variables). Large variations in the stripping section of the extractive column were observed, resulting from the variation of the molar density of the liquid mixture in addition to the delay in the startup operation when the amount of ethanol in the recovery column increases.

RESUMO Neste trabalho foi utilizado um sistema hidropônico com os canais de cultivo em nível com o objetivo de avaliar a cultura do coentro submetida a diferentes intervalos para recirculação da solução nutritiva em interação com o uso de água doce e salobra. O experimento foi conduzido em blocos casualizados com cinco repetições, em esquema fatorial 2 x 4, entre fevereiro e março de 2014. Avaliaram-se dois níveis de condutividade elétrica (CE) da água: 0,32 e 4,91 dS m-1, além de quatro frequências de recirculação da solução nutritiva (intervalos de 0,25; 2; 4 e 8 h). Este delineamento experimental foi aplicado nas avaliações realizadas aos 10, 15 e 25 dias após o transplantio (DAT). Adicionalmente, aos 21 DAT foram estabelecidas subparcelas visando avaliar o efeito da posição das plantas (inicial, intermediária e final) nos perfis hidropônicos. É viável adotar-se recirculação da solução nutritiva a cada 8 h sem perdas de produção. O uso da água salobra (CE = 4,91 dS m-1) pode ser uma alternativa para o cultivo do coentro hidropônico, mesmo com reduções na produção, porém sem efeitos depreciativos à qualidade visual do produto. As plantas cultivadas nas posições inicial e intermediária dos perfis hidropônicos apresentaram maior produção.

ABSTRACT The present study used a hydroponic system with leveled channels, in order to evaluate coriander cultivation under different intervals of nutrient solution recirculation and the use of freshwater and brackish water. The experiment was carried out in a randomized block design with five replicates, in a 2 x 4 factorial scheme, from February to March 2014. Two levels of electrical conductivity (EC) of water (0.32 and 4.91 dS m-1) and four frequencies of nutrient solution recirculation (at intervals of 0.25, 2, 4 and 8 h) were evaluated. This experimental design was adopted in the evaluations performed at 10, 15 and 25 days after transplantation (DAT). Additionally, at 21 DAT subplots were established for the evaluation of plant position (initial, intermediate and final) along the hydroponic channels. It is viable to use nutrient solution recirculation every 8 h, without production losses. The use of brackish water (EC = 4.91 dS m-1) may be an alternative for the hydroponic cultivation of coriander, despite the reduction in production, but without any damage on the visual aspect of the product. Plants grown at the initial and intermediate positions along the hydroponic channels showed higher production.

OBJECTIVES: Cardiology referral is common for patients admitted for non-cardiac diseases. Recommendations from cardiologists may involve complex and aggressive treatments that could be ignored or denied by other physicians. The purpose of this study was to compare the outcomes of patients who were given recommendations during cardiology referrals and to examine the clinical outcomes of patients who did not follow the recommendations. METHODS: We enrolled 589 consecutive patients who received in-hospital cardiology consultations. Data on recommendations, implementation of suggestions and outcomes were collected. RESULTS: Regarding adherence of the referring service to the recommendations, 77% of patients were classified in the adherence group and 23% were classified in the non-adherence group. Membership in the non-adherence group (p<0.001; odds ratio: 10.25; 95% CI: 4.45-23.62) and advanced age (p = 0.017; OR: 1.04; 95% CI: 1.01-1.07) were associated with unfavorable outcomes. Multivariate analysis identified four independent predictors of adherence to recommendations: follow-up notes in the medical chart (p<0.001; OR: 2.43; 95% CI: 1.48-4.01); verbal reinforcement (p = 0.001; OR: 1.86; 95% CI: 1.23-2.81); a small number of recommendation (p = 0.001; OR: 0.87; 95% CI: 0.80-0.94); and a younger patient age (p = 0.002; OR: 0.98; 95% CI: 0.96-0.99). CONCLUSIONS: Poor adherence to cardiology referral recommendations was associated with unfavorable clinical outcomes. Follow-up notes in the medical chart, verbal reinforcement, a limited number of recommendations and a patient age were associated with greater adherence to recommendations.

Os líquidos iônicos (ILs) são sais líquidos a baixas temperaturas, tipicamente com pontos de fusão abaixo de 100 ºC. Nos últimos anos, as propriedades de vários ILs têm sido extensivamente estudadas e, em casos específicos, podem ser considerados como solventes verdes capazes de substituir solventes orgânicos tradicionais. Neste trabalho, ILs derivados de triazol tem sido sintetizados e a solubilidade em diferentes solventes aumenta com a constante dieléctrica dos solventes considerados. Três novos ILs 1,2,3-triazólicos foram utilizados para o pré-tratamento do bagaço de cana. O efeito deste pré-tratamento da biomassa lignocelulósica foi analisado por microscopia eletrônica de varredura, mostrando um aumento da superfície de exposição das amostras de bagaço como alterações estruturais na fibra.

Ionic liquids (ILs) are salts which are liquid at low temperatures, typically with melting points under 100 ºC. In recent years, the properties of many ILs have been extensively studied and have been considered as green solvents capable of replacing traditional organic solvents. Herein, ILs derived from triazole have been synthesized, thus solubility in different solvents increases with the dielectric constant of the considered solvents. Three novel 1,2,3-triazolium-based were used for the pretreatment of sugarcane bagasse. The effect of this pretreatment on lignocellulosic biomass was analyzed by scanning electron microscopy, showing an increase in the exposure surface of the bagasse samples as structural changes in the fiber.

Os experimentos objetivaram avaliar em condições de casa de vegetação o biocontrole dos fitopatógenos Rhizoctonia solani (RS) e Fusarium oxysporum f.sp. phaseoli (FOP) em alface (Lactuca sativa L.) cultivar Regina, e feijão-vagem (Phaseolus vulgaris L.) cultivar Alessa, respectivamente, utilizando como agentes antagonistas, 10 isolados de Trichoderma spp. selecionados em testes in vitro. Foram feitos biopreparados à base de arroz previamente colonizado por isolados de Trichoderma spp. e posteriormente triturados. Para a realização dos testes, os biopreparados foram inoculados previamente na proporção de 10(9) conídios.mL-1, em substrato comercial para produção de mudas. Após sete dias, os patógenos foram introduzidos separadamente em duas concentrações distintas: R. solani na proporção de 144 mg de meio de arroz por kg de substrato e F. oxysporum f.sp. phaseoli inoculado na forma de suspensão contendo 4,75 x 10(6) conídios.mL-1. Avaliou-se a influência dos biopreparados na % de damping-off de pós-emergência em plantas de alface e a severidade de murcha em plantas de feijão-vagem. O biopreparado referente ao isolado T-03 foi o mais eficiente no controle de R. solani em plantas de alface cultivar Regina, por ter reduzido a incidência de damping-off de pós-emergência nessa cultura. Por outro lado, nenhum dos biopreparados apresentou efeito antagonista satisfatório à F. oxysporum f.sp. phaseoli em plantas de feijão-vagem.

The experiments aimed to evaluate under greenhouse conditions the biocontrol of plant pathogens Rhizoctonia solani (RS) and Fusarium oxysporum f.sp. phaseoli (FOP) in lettuce (Lactuca sativa L.) cultivar Regina and in common bean (Phaseolus vulgaris L.) cultivar Alessa, respectively, using as antagonistic agents 10 Trichoderma spp. isolates selected from in vitro tests. Inoculants were prepared with rice previously colonized by Trichoderma spp. and subsequently ground. For the tests, the antagonists were previously inoculated at a ratio of 10(9) conidia mL-1 on commercial substrate for seedling production. Following seven days, the pathogens were separately introduced at two different concentrations: R. solani at a ratio of 144 mg rice medium per kg of substrate and F oxysporum f.sp. phaseoli inoculated as a suspension containing 4.75 x 10(6) conidia mL-1. The influence of antagonists on % post-emergence damping-off in lettuce and the severity of wilt in common beans were evaluated. The biopreparation with T-03 isolate was most effective in controlling R. solani in lettuce cultivar Regina, for having reduced the incidence of post-emergence damping-off in this culture. On the other hand, none of the biopreparations showed satisfactory antagonistic effect on F. oxysporum f.sp. phaseoli in common bean plants.

A monitorização de ensaios experimentais tem registado desenvolvimentos significativos nos últimos anos mediante o recurso à fotogrametria e ao processamento de imagem. Neste artigo pretende-se demostrar a aplicabilidade prática destas novas técnicas na monitorização de ensaios até à rotura. Neste trabalho é dada especial atenção à curvatura, à rotação plástica e à contribuição do betão entre fendas para o aumento da rigidez à flexão, i.e., o "tension stiffening effect", os quais são fundamentais para caracterizar o comportamento estrutural de vigas de betão armado, tanto em serviço como em estado limite último. Verifica-se que estas novas técnicas permitem monitorizar um número muito elevado de pontos, complementando os métodos tradicionais de monotorização, e possibilitando a determinação de informação impossível de obter através dos métodos tradicionais.

Innovative procedures for monitoring experimental tests using photogrammetry and image processing have been recently proposed. This manuscript aims at providing a practical demonstration of the advantages of using these new techniques in experimental tests up to failure. In this scope, focus is given to the curvature, rotation and to the tension stiffening effect, i.e., the contribution of the concrete between cracks to increase the bending stiffness. These parameters are crucial to describe the structural behavior of reinforced concrete beams both in serviceability and in ultimate limit states. These new techniques allow monitoring a high number of points, enhancing the traditional monitoring methods and providing more information which would be impossible to obtain using the traditional methods.

Abstract: En | Text: En | PDF: En

Viscosities of four binaries mixtures [soybean biodiesel + diesel oil (or n-hexadecane) and coconut biodiesel + diesel oil (or n-hexadecane)] have been determined at T = (293.15, 313.15, 333.15, 353.15, 373.15) K and atmospheric pressure over the entire composition range. Experimental data were fitted to the Andrade equation and the adjustable parameters and the standard deviations between experimental and calculated values were estimated. From the experimental data, the viscosity deviations, <img src="/img/revistas/bjce/v29n3/21e02.jpg" alt="" align="absmiddle" />, were calculated by using the Redlich - Kister polynomial equation. The comparison between experimental data determined in this work and four predictive methods used for the estimation of viscosities of biodiesel fuels (based on their fatty acid composition) is discussed.

OBJECTIVE: To evaluate Brazil's public health surveillance system (HSS), identifying its core capacities, shortcomings, and limitations in dealing with public health emergencies, within the context of the International Health Regulations (IHR 2005). METHODS: In 2008-2009 an evaluative cross-sectional study was conducted using semistructured questionnaires administered to key informants (municipal, state, and national government officials) to assess Brazilian HSS structure (legal framework and resources) and surveillance and response procedures vis-à-vis compliance with the IHR (2005) requirements for management of public health emergencies of national and international concern. Evaluation criteria included the capacity to detect, assess, notify, investigate, intervene, and communicate. Responses were analyzed separately by level of government (municipal health departments, state health departments, and national Ministry of Health). RESULTS: Overall, at all three levels of government, Brazil's HSS has a well-established legal framework (including the essential technical regulations) and the infrastructure, supplies, materials, and mechanisms required for liaison and coordination. However, there are still some weaknesses at the state level, especially in land border areas and small towns. Professionals in the field need to be more familiar with the IHR 2005 Annex 2 decision tool (designed to increase sensitivity and consistency in the notification process). At the state and municipal level, the capacity to detect, assess, and notify is better than the capacity to investigate, intervene, and communicate. Surveillance activities are conducted 24 hours a day, 7 days a week in 40.7% of states and 35.5% of municipalities. There are shortcomings in organizational activities and methods, and in the process of hiring and training personnel. CONCLUSIONS: In general, the core capacities of Brazil's HSS are well established and fulfill most of the requisites listed in the IHR 2005 with respect to both structure and surveillance and response procedures, particularly at the national and state levels.

OBJETIVO: Evaluar el sistema de vigilancia de salud pública del Brasil, identificando sus capacidades básicas, deficiencias y limitaciones para manejar emergencias de salud pública, dentro del contexto del Reglamento Sanitario Internacional (RSI 2005). MÉTODOS: En el período 2008-2009 se llevó a cabo un estudio transversal de evaluación utilizando cuestionarios semiestructurados administrados a informantes clave (funcionarios del gobierno municipal, estatal y nacional) a fin de evaluar la estructura del sistema de vigilancia de salud pública del Brasil (marco jurídico y recursos), y la vigilancia y los procedimientos de respuesta, con relación al cumplimiento de los requisitos del RSI 2005 para el manejo de emergencias de salud pública de importancia nacional e internacional. Los criterios de evaluación incluyeron la capacidad de detectar, evaluar, notificar, investigar, intervenir y comunicar. Las respuestas se analizaron por separado según el nivel gubernamental (departamentos de salud municipales y estatales y ministerio de salud nacional). RESULTADOS: En general, en los tres niveles del gobierno, el sistema de vigilancia de salud pública del Brasil tiene un marco jurídico bien establecido (incluidas las reglamentaciones técnicas esenciales) y la infraestructura, los suministros los materiales y los mecanismos requeridos para el enlace y la coordinación. Sin embargo, todavía hay algunos puntos débiles a nivel estatal, especialmente en las zonas fronterizas y los pueblos pequeños. Los profesionales de campo deben conocer más la herramienta de decisión del anexo 2 del RSI 2005 (diseñada para aumentar la sensibilidad y la consistencia del proceso de notificación). En el nivel estatal y municipal, la capacidad para detectar, evaluar y notificar es mejor que la capacidad para investigar, intervenir y comunicar. Las actividades de vigilancia se llevan a cabo 24 horas al día, 7 días a la semana, en 40,7% de los estados y 35,5% de los municipios. Existen deficiencias en las actividades de organización y los métodos, y en el proceso de contratación y capacitación del personal. CONCLUSIONES: En general, las capacidades básicas del sistema de vigilancia de salud pública del Brasil están bien establecidas y cumplen la mayoría de los requisitos enumerados en el RSI 2005, tanto con respecto a la estructura como a la vigilancia y los procedimientos de respuesta, en particular en los niveles nacional y estatal.
