ABSTRACT Purpose To characterize hearing thresholds at frequencies of 500, 1000, 2000 and 4000 Hz in children undergoing reimplantation with a follow-up of at least 10 years. Methods Retrospective review of medical records of children who underwent reimplantation surgery for at least 10 years. The auditory thresholds obtained in free-field pure tone audiometry with the cochlear implant were evaluated at frequencies of 500, 1000, 2000 and 4000 Hz at four different times: 1 (before failure), 2 (activation), 3 (five years after reimplantation) and 4 (ten years after reimplantation, regardless of the time of use of the 2nd CI) in patients with a follow-up of at least 10 years. Results Evaluating patients who underwent reimplantation, it was observed that the thresholds of 500, 1000, 2000, 4000 Hz were similar in the long term to those obtained in patients who were implanted only once, thus not presenting damage in the detection of sounds. Conclusion Reimplantation had no long-term effect on the hearing thresholds obtained in children who underwent this surgery due to internal component failure.

RESUMO Objetivo Caracterizar os limiares auditivos nas frequências de 500, 1000, 2000 e 4000 Hz em crianças submetidas ao reimplante com follow-up de no mínimo 10 anos. Método Revisão retrospectiva de prontuários de crianças submetidas a cirurgia de reimplante há pelo menos 10 anos. Foram avaliados os limiares auditivos obtidos na audiometria tonal liminar em campo livre com o implante coclear nas frequências de 500, 1000, 2000 e 4000 Hz em quatro momentos distintos: 1 (antes da falha), 2 (ativação), 3 (cinco anos após o reimplante) e 4 (dez anos após o reimplante, independentemente do tempo de uso do uso do 2o IC) em pacientes com follow-up de no mínimo 10 anos. Resultados Avaliando-se pacientes submetidos ao reimplante, observou-se que os limiares de 500, 1000, 2000, 4000 Hz apresentaram-se a longo prazo semelhante àqueles obtidos nos pacientes implantados somente uma única vez, não apresentando prejuízo assim na detecção dos sons. Conclusão O reimplante não teve efeito de longo prazo sobre os limiares auditivos obtidos em crianças que se submeteram a esta cirurgia por falha do componente interno.

Resumo: A substituição das paisagens naturais por ambientes antropizados tem levado à perda de habitat e, consequentemente, ao declínio populacional e extinção de muitas espécies. Várias estratégias como a criação de Unidades de Conservação (UCs) e o pagamento de serviços ecossistêmicos têm sido adotadas para mitigar as consequências da crise de biodiversidade. Em Rio Verde, estado de Goiás, foi estabelecido um Programa Produtores de Água (PPA) que prevê o pagamento de serviços ecossistêmicos pela manutenção da vegetação ripária na região do ribeirão Abobora que abastece a cidade. Diante da ausência de estudos de diagnóstico ambiental da região, o presente estudo contribui para reduzir algumas lacunas de conhecimento, através da: i) caracterização da paisagem na área deste PPA, ii) caracterização das espécies da fauna (anfíbios, aves, peixes e mamíferos terrestres de médio e grande porte) e flora lenhosa que ocorrem neste local, iii) comparação da diversidade de espécies (fauna e flora) encontrada na área de estudo com aquela observada na rede de áreas protegidas do Cerrado. Nossos resultados revelam baixo índice de cobertura vegetal nativa (~21% da área total), mas por outro lado, registramos 300 espécies, sendo 20 de anfíbios anuros, 100 aves, 10 peixes, 16 mamíferos terrestres (médio e grande porte) e 154 plantas lenhosas. A nossa amostragem compreende espécies que são consideradas endêmicas do Cerrado (p.ex. Anfíbio - Barycholos terntezi e Mamífero - Callithrix penicillata), ameaçadas de extinção (p.ex. Mamíferos - Herpailurus yagouaroundi, Myrmecophaga tridactyla e Tapirus terrestris) ou exótica invasora (Mamífero - Sus scrofa). Os resultados apresentados no presente estudo são relevantes e podem auxiliar na proposição de ações de manejo no âmbito deste importante programa de pagamento por serviços ambientais.

Abstract: The replacement of natural landscapes by anthropic environments has led to habitat loss and consequently, to the decline and extinction of many species populations. Several strategies, such as the creation of protected areas (PAs) and payment for ecosystem services have been adopted to mitigate the consequences of this biodiversity crisis. In Rio Verde, Goiás, Brazil, a Water Producer Program (WPP) was established, which provides payment for ecosystem services for the maintenance of riparian vegetation in the region of the Ribeirão Abóbora, a river which supplies the city and metropolitan area. In the absence of environmental diagnostic studies in the region, this present study contributes to reducing some knowledge gaps, through the: (i) characterization of the landscape in the WPP area, (ii) characterization of species of fauna (amphibians, birds, fish, and medium and large terrestrial mammals) and woody flora that occur in this area, and (iii) comparison of species diversity (fauna and flora) found in our study area with the diversity observed in the Cerrado protected area network. Our results reveal a low native vegetation cover (~21% of total area), but we recorded 300 total species: 20 species of anuran amphibians, 100 birds, 10 fish, 16 terrestrial mammals (medium and large), and 154 woody plants. Our sample comprises species considered endemic to the Cerrado (e.g., Anuran - Barycholos terntezi and Mammal - Callithrix penicillata), threatened species (e.g., Mammals - Herpailurus yagouaroundi, Myrmecophaga tridactyla and Tapirus terrestris), and exotic invasive species (Mammal - Sus scrofa). The results presented in this study are relevant and may help in the proposal of management actions within the scope of this important program of payment for environmental services.

Resumo Esta pesquisa busca analisar o conhecimento dos moradores sobre o território, Complexo Industrial e Portuário do Pecém (CIPP), qualidade de vida das comunidades que vivem no entorno dos empreendimentos, além da prevalência de hipertensão e excesso de peso. Trata-se de um inquérito epidemiológico, de base domiciliar, envolvendo quatro áreas da Estratégia de Saúde da Família (ESF) do Município de São Gonçalo do Amarante e uma de Caucaia, Ceará, Brasil. O estudo foi realizado entre 10/2017 e 03/2018, em que foram realizadas aferições antropométricas e pressão arterial e coletados dados sociodemográficos e o conhecimento sobre comunidade, CIPP e qualidade de vida. Dos 503 adultos entrevistados, 69,8% eram do sexo feminino e a média de idade foi 44 anos. Parada foi a área que relatou o maior percentual de problemas relacionados às partículas aéreas (51,1%), pior conceito em relação ao CIPP (40,1% ruim), maior percentual de piora da qualidade de vida (29,1%) e maior desejo de mudar (31,5%). Pecém apresentou maior percentual de problemas na comunidade relacionados à violência, consumo de drogas ilícitas e prostituição. Conclui-se que se apresenta indícios de impacto na saúde e qualidade de vida das populações locais sem maiores benefícios diretos no trabalho/renda.

Abstract This research aimed to analyze the dwellers’ knowledge of the territories, Pecém Port and Industrial Compound (CIPP), the quality of life of the communities living in the vicinity of the enterprises, and the prevalence of hypertension and overweight. This is a home-based, epidemiological survey of four areas of the Family Health Strategy (ESF) in São Gonçalo do Amarante and one area of the ESF in Caucaia, Ceará, Brazil. The study was carried out between 10/2017 and 03/2018. Anthropometric and blood pressure measurements were performed, and sociodemographic data and knowledge about community, the CIPP, and quality of life were collected. A total of 69.8% of the 503 adults interviewed were female, and the mean age was 44 years. Parada was the area reporting the highest percentage of problems related to air particles (51.1%), the worst concept regarding the CIPP (40.1% bad), the highest percentage of worse quality of life (29, 1%), and greater desire to move to another place (31.5%). Pecém had the highest percentage of community problems related to violence, consumption of illicit drugs, and prostitution. We concluded that there are signs of impact on local populations’ health and quality of life without more significant direct work/income benefits.

Resumo: O objetivo deste trabalho foi determinar os parâmetros genéticos e a eficiência de diferentes índices de seleção para linhagens de alface de folhas vermelhas (Lactuca sativa var. crispa) biofortificada e com potencial agronômico e nutricional. O experimento foi conduzido em delineamento de blocos ao acaso, com três repetições e 31 genótipos de alface do tipo crespa e com pigmentação roxa: a cultivar Belíssima, com baixa quantidade de carotenoides e rica em antocianina; e 30 linhagens provenientes do cruzamento entre as cultivares Belíssima e Uberlândia 10000, rica em carotenoides e com baixo teor de antocianina. As características avaliadas foram: massa verde total (g), diâmetro do caule (cm), número de folhas, diâmetro da planta (cm), temperatura foliar (°C), índice de desenvolvimento de análise de planta de solo (SPAD), teor de antocianina (mg por 100 g de amostra) e pendoamento (dias após a semeadura). Para as estimativas dos ganhos de seleção, foram selecionados 12 genótipos por meio de índices de seleção. O índice clássico proposto por Smith & Hazel e o índice da soma de “ranks” de Mulamba & Mock proporcionaram os maiores ganhos de seleção na alface biofortificada. O coeficiente de determinação genotípica para número de folhas, teor de antocianina, pendoamento e índice SPAD é de alta magnitude.

Abstract: The objective of this work was to determine the genetic parameters and the efficiency of different selection indices for biofortified red leaf lettuce (Lactuca sativa var. crispa) lines with agronomic and nutritional potential. The experiment was carried out in a randomized complete block design with three replicates and 31 crisp-textured and red-tinted leaf lettuce genotypes: the Belíssima cultivar, with a low carotenoid content and rich in anthocyanins; and 30 lines from the cross between the Belíssima and Uberlândia 10000 cultivars, rich in carotenoids and with a low anthocyanin content. The assessed traits were: total green mass (g), stem diameter (cm), leaf count, plant diameter (cm), foliar temperature (°C), soil plant analysis development (SPAD) index, anthocyanin content (mg 100 g-1 sample), and bolting (days after sowing). To estimate selection gains, 12 genotypes were selected through selection indices. The traditional index proposed by Smith & Hazel and the sum of ranks index by Mulamba & Mock provided the highest selection gains in the biofortified lettuce. The coefficient of genotypic determination for leaf count, anthocyanin content, bolting, and SPAD index is of high magnitude.

Abstract: En Pt

In early 2020, the World Health Organization (WHO) recognized the pandemic situation of the new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2), which causes Coronavirus Disease-2019 (COVID-19). In Brazil by the end of April 2020, another 110 thousand cases and 5,000 deaths had been confirmed. The scarcity of laboratory resources and overload of the care network, added to the broad clinical spectrum of the disease, can make it difficult to capture all mortality from this disease through epidemiological surveillance based on individual notification of cases. The aim of this study was to evaluate the excess of deaths in Brazilian capitals with the highest incidence of COVID-19, as a way of validating the method, we also evaluated a capital with low incidence. We assessed weekly mortality from all causes during the year 2020, up to the epidemiological week 17, compared with the previous year. The data were obtained through the National Civil Registry Information Center (CNIRC, acronym in Portuguese). We estimate the expected mortality and the 95% confidence interval by projecting the observed mortality in 2019 for the population of 2020. In the five capitals with the highest incidences it was possible to identify excess deaths in the pandemic period, the age group most affected were those over 60 years old, 31% of the excess deaths occurred in the population between 20 and 59 years old. There was a strong correlation (r = 0.94) between the excess of deaths in each city and the number of deaths confirmed by epidemiological surveillance. There was no excess of deaths in the capital with the lowest incidence, nor among the population under 20 years old. We estimate that epidemiological surveillance managed to capture only 52% of all mortality associated with the COVID-19 pandemic in the cities studied. Considering the simplicity of the method, its low cost and reliability for assessing the real burden of the disease, we believe that the assessment of excess mortality associated with the COVID-19 pandemic should be widely used as a complementary tool to regular epidemiological surveillance and its use should be encouraged by WHO.

No início de 2020 a Organização Mundial da Saúde (OMS) reconheceu a situação de pandemia do novo coronavírus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2), causador da Coronavirus Disease-2019 (COVID-19). No Brasil até o final de abril de 2020 já tinham sido confirmados mais 110 mil casos e de 5 mil óbitos. A escassez de recursos laboratoriais e sobrecarga da rede assistencial, somados ao amplo espectro clínico da doença, pode dificultar a captação de toda a mortalidade por esta doença pela vigilância epidemiológica baseada na notificação individual dos casos. O objetivo deste estudo foi avaliar o excesso de mortes nas capitais brasileiras com maiores incidências de COVID-19, como forma de validação do método avaliamos, também, uma capital com baixa incidência. Nós avaliamos a mortalidade semanal por todas as causas durante o ano de 2020, até a semana epidemiológica 17, comparando com o ano anterior. Os dados foram obtidos através da Central Nacional de Informações do Registro Civil (CNIRC). Nós estimamos a mortalidade esperada e o intervalo de confiança de 95% projetando a mortalidade observada em 2019 para a população de 2020. Nas cinco capitais com maiores incidências foi possível identificar excesso de mortes no período da pandemia, a faixa etária mais afetada foram aqueles com mais de 60 anos, 31% do excesso de mortes ocorreu na população entre 20 e 59 anos. Houve uma forte correlação (r=0.94) entre o excesso de mortes em cada cidade e o número de mortes confirmados pela vigilância epidemiológica. Não houve excesso de mortes na capital com mais baixa incidência, nem entre a população com menos de 20 anos. Estimamos que a vigilância epidemiológica conseguiu captar apenas 52% de toda a mortalidade associada à pandemia de COVID-19 nas cidades estudadas. Considerando a simplicidade do método, seu baixo custo e confiabilidade para avaliação da carga real da doença, acreditamos que a avaliação do excesso de mortalidade associado à pandemia de COVID-19 deveria ser amplamente utilizada como ferramenta complementar à vigilância epidemiológica regular e ter seu uso incentivado pela OMS.

Abstract Background: Human herpesviruses (HHVs) are responsible for a significant number of clinical manifestations in systemic lupus erythematous (SLE) patients. The aim of this study was to determine the frequency of active HHV infections in SLE patients and correlating them with disease activity. Methods: Serum samples were collected from 71 SLE patients and their DNAs were extracted and analyzed to detect HHV-DNA viruses using the nucleic acid amplification technique. Results: Fifteen out of the 71 (21.1%) patients tested positive for the HHV-DNA virus. Of them, 11/15 HHV-DNA-positive patients (73.3%) had SLE activity index (SLEDAI - Systemic Lupus Erythematosus Disease Activity Index) ≥8 (p = 0.0001). Active HCMV infection was the mostly frequently observed infection, occurring in 6/15 patients (40%). The frequencies of other active viral infections were 22% for HSV-1, 16.7% for HHV-7, and 5.5% for HSV-2. Viral coinfection (two or more viruses detected in the same sample) occurred in three patients (16.7%). Active HHV infections in SLE patients are more frequent in those with active SLE (≥8), who is at high risk of HHV reactivation and HCMV disease. Conclusion: Viral surveillance is important to identify active HHV infections that can cause clinical symptoms and other complication in SLE patients.

Abstract INTRODUCTION: In March 2020, the World Health Organization declared the coronavirus disease (COVID-19) outbreak a pandemic. In Brazil, 110 thousand cases and 5,901 deaths were confirmed by the end of April 2020. The scarcity of laboratory resources, the overload on the service network, and the broad clinical spectrum of the disease make it difficult to document all the deaths due to COVID-19. The aim of this study was to assess the mortality rate in Brazilian capitals with a high incidence of COVID-19. METHODS: We assessed the weekly mortality between epidemiological week 1 and 16 in 2020 and the corresponding period in 2019. We estimated the expected mortality at 95% confidence interval by projecting the mortality in 2019 to the population in 2020, using data from the National Association of Civil Registrars (ARPEN-Brasil). RESULTS: In the five capitals with the highest incidence of COVID-19, we identified excess deaths during the pandemic. The age group above 60 years was severely affected, while 31% of the excess deaths occurred in the age group of 20-59 years. There was a strong correlation (r = 0.94) between excess deaths and the number of deaths confirmed by epidemiological monitoring. The epidemiological surveillance captured only 52% of all mortality associated with the COVID-19 pandemic in the cities examined. CONCLUSIONS: Considering the simplicity of the method and its low cost, we believe that the assessment of excess mortality associated with the COVID-19 pandemic should be used as a complementary tool for regular epidemiological surveillance.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2015 suas primeiras recomendações sobre a abordagem do CHC. Desde então, novas evidências sobre o diagnóstico e tratamento do CHC foram relatadas na literatura médica, levando a diretoria da SBH a promover uma reunião monotemática sobre câncer primário de fígado em agosto de 2018 com o intuito de atualizar as recomendações sobre o manejo da neoplasia. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização baseada em evidências científicas visando que pudesse nortear a prática clínica multidisciplinar do CHC. O texto resultante foi submetido a avaliação e aprovação de todos membros da SBH através de sua homepage. O documento atual é a versão final que contêm as recomendações atualizadas e revisadas da SBH.

ABSTRACT Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2015 its first recommendations about the management of HCC. Since then, new data have emerged in the literature, prompting the governing board of SBH to sponsor a single-topic meeting in August 2018 in São Paulo. All the invited experts were asked to make a systematic review of the literature reviewing the management of HCC in subjects with cirrhosis. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of updated recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present manuscript is the final version of the reviewed manuscript containing the recommendations of SBH.

ABSTRACT Objective: To verify the effectiveness of a nursing training program in the area of children’s hearing health using interactive tele-education. Methods: Interrupted time series with non-random control group pre-test/ post-test. A cohort of 41 nurses, with no previous formal training in hearing health. A “Children’s Hearing Health” Cybertutor was employed. The effectiveness of the nursing training was verified by comparing pre- versus post-training performance and by analyzing responses to an evaluation questionnaire. Results: Following training, the performance was significantly better in all domains assessed and in the total score. The evaluation questionnaire demonstrated that the Cybertutor was well accepted and the performance revealed in the pre-training phase demonstrated the need for children´s hearing health training. Conclusion: The effectiveness of the nursing training program in the area of Children’s Hearing Health using interactive tele-education could be proven, since there was an improvement in performance in all domains evaluated.

SUMMARY: The infrapatellar branch of the saphenous nerve is a cutaneous nerve that innervates the area surrounding the patella and contributes to the peripatellar plexus. This nerve is target to iatrogenic injuries during a great deal of knee procedures, such as tendon harvesting, total knee arthroplasty and medial arthroscopic approaches to the knee. Lesion to this nerve can produce sensorial loss at its innervation territory. The study conducted herein aims to observe the anatomical aspects of the infrapatellar branch in cadaveric specimens. The infrapatellar branch of the saphenous nerve of 40 male cadavers was dissected with the purpose of identifying the number of branches, its relation with the patella, tibial tuberosity and sartorius muscle. The nerve was dissected and several measurements were performed with the aid of a digital caliper. Statistical analysis was performed with the MedCalc 16.1 software. The infrapatellar branch of the saphenous nerve was present in 100 % of the sample. Its mean distance from its origin to its branching point was 16.35±6.48 mm on the right and 21.94±4.31 mm on the left, with statistically significant differences (p < 0.05). A relatively safe zone for surgery was observed on the superior and medial aspect of the patella, which received less branches.

RESUMEN: La rama infrapatelar del nervio safeno es un nervio cutáneo que inerva el área que rodea la patela y contribuye al plexo peripatelar. Este nervio es objeto de lesiones iatrogénicas durante una gran cantidad de procedimientos de rodilla, como la extracción de tendones, la artroplastía total de rodilla y los abordajes artroscópicos mediales de la rodilla. La lesión de este nervio puede producir pérdida sensorial en su territorio de inervación. El estudio realizado aquí tiene como objetivo observar los aspectos anatómicos de la rama infrapatelar en muestras de cadáveres. La rama infrapatelar del nervio safeno de 40 cadáveres masculinos se disecó con el propósito de identificar el número de ramas, su relación con la patela, la tuberosidad tibial y el músculo sartorio. Se disecó el nervio y se realizaron varias mediciones con la ayuda de un calibrador digital. El análisis estadístico se realizó con el software MedCalc 16.1. La rama infrapatelar del nervio safeno estaba presente en el 100 % de las muestras. La distancia media desde su origen hasta su punto de ramificación fue de 16,35±6,48 mm a la derecha y de 21,94±4,31 mm a la izquierda, con diferencias estadísticamente significativas (p <0,05). Se identificó una zona relativamente segura para la cirugía en el aspecto superior y medial de la patela, que recibió menos ramas.

Abstract: Brazilian productivity of eucalyptus trees is one of the highest in the world, and it has sustainable and viable conditions to supply the demand for woody biomass in a large quantity and diversity. This favorable situation makes Brazil one of the countries with the greatest potential for the production development of torrefied woody biomass on a commercial scale. Torrefaction is a mild pyrolysis applied to increase the energy quality of the feedstock. The aim of this study was to evaluate the Brazilian potential of woody biomass torrefaction for energy purposes. An experimental study was performed evaluating this thermal treatment of eucalyptus wood chips on a semi-continuous screw reactor developed by a Brazilian university. The results showed the increases in the energy quality of eucalyptus wood chips as a function of torrefaction temperature and time. This thermal treatment was technically feasible for the hygroscopicity reduction and the increases of fixed carbon and calorific values of the woody biomass.

Abstract: Pyrolysis is a promising technology for thermal conversion of lignocellulosic biomasses into a higher added value fuel. The aim of this study was to analyze the potential of four agroforestry biomasses to produce energy as a raw material or as a bio-coal. In this study, slow pyrolysis was conducted in three final temperatures to evaluate the bio-coal production of four agroforestry biomasses widely available in Brazil. The biomasses used were sugarcane bagasse (Saccharum sp.), bamboo (Dendrocalamus giganteus), straw bean (Phaseolus vulgaris) and eucalypts wood chips (Eucalyptus sp.). In the first part was presented the raw biomasses proprieties, such as lignin, carbon, hydrogen and ash contents. In the second part was showed the bio-coal proprieties, such as gravimetric and fixed carbon yields, fixed carbon and ash contents. These bio-coal results were showed as a function of final temperature of pyrolysis. The best energy indicators for bio-coal production, such as fixed carbon yield, high heating value, was observed in the bamboo and eucalypts. The bagasse and straw bean biomasses have high concentrations of ash and low lignin content when compared with the other biomasses assessed and are less suitable to produce bio-coal.

Abstract: En | Text: En | PDF: En

Abstract Salmonella Gallinarum is a host-restrict pathogen that causes fowl typhoid, a severe systemic disease that is one of the major concerns to the poultry industry worldwide. When infecting the bird, SG makes use of evasion mechanisms to survive and to replicate within macrophages. In this context, phoPQ genes encode a two-component regulatory system (PhoPQ) that regulates virulence genes responsible for adaptation of Salmonella spp. to antimicrobial factors such as low pH, antimicrobial peptides and deprivation of bivalent cations. The role of the mentioned genes to SG remains to be investigated. In the present study a phoPQ-depleted SG strain (SG ΔphoPQ) was constructed and its virulence assessed in twenty-day-old laying hens susceptible to fowl typhoid. SG ΔphoPQ did cause neither clinical signs nor mortality in birds orally challenged, being non-pathogenic. Furthermore, this strain was not recovered from livers or spleens. On the other hand, chickens challenged subcutaneously with the mutant strain had discreet to moderate pathological changes and also low bacterial counts in liver and spleen tissues. These findings show that SG ΔphoPQ is attenuated to susceptible chickens and suggest that these genes are important during chicken infection by SG.
