Acute respiratory viral infections in pediatric cancer patients undergoing chemotherapy

AbstractObjectiveTo estimate the prevalence of infection by respiratory viruses in pediatric patients with cancer and acute respiratory infection (ARI) and/or fever.MethodsCross-sectional study, from January 2011 to December 2012. The secretions of nasopharyngeal aspirates were analyzed in children younger than 21 years with acute respiratory infections. Patients were treated at the Grupo em Defesa da Criança Com Câncer (Grendacc) and University Hospital (HU), Jundiaí, SP. The rapid test was used for detection of influenza virus (Kit Biotrin, Inc., Ireland), and real-time multiplex polymerase chain reaction (FTD, Respiratory pathogens, multiplex Fast Trade Kit, Malta) for detection of influenza virus (H1N1, B), rhinovirus, parainfluenza virus, adenovirus, respiratory syncytial virus, human parechovirus, bocavirus, metapneumovirus, and human coronavirus. The prevalence of viral infection was estimated and association tests were used (χ2 or Fisher's exact test).Results104 samples of nasopharyngeal aspirate and blood were analyzed. The median age was 12±5.2 years, 51% males, 68% whites, 32% had repeated ARIs, 32% prior antibiotic use, 19.8% cough, and 8% contact with ARIs. A total of 94.3% were in good general status. Acute lymphocytic leukemia (42.3%) was the most prevalent neoplasia. Respiratory viruses were detected in 50 samples: rhinoviruses (23.1%), respiratory syncytial virus AB (8.7%), and coronavirus (6.8%). Codetection occurred in 19% of cases with 2 viruses and in 3% of those with 3 viruses, and was more frequent between rhinovirus and coronavirus 43. Fever in neutropenic patients was observed in 13%, of which four (30.7) were positive for viruses. There were no deaths.ConclusionsThe prevalence of respiratory viruses was relevant in the infectious episode, with no increase in morbidity and mortality. Viral co-detection was frequent in patients with cancer and ARIs

Evaluation of formal IDEs for human-machine interface design and analysis: the case of CIRCUS and PVSio-web

Critical human-machine interfaces are present in many systems including avionics systems and medical devices. Use error is a concern in these systems both in terms of hardware panels and input devices, and the software that drives the interfaces. Guaranteeing safe usability, in terms of buttons, knobs and displays is now a key element in the overall safety of the system. New integrated development environments (IDEs) based on formal methods technologies have been developed by the research community to support the design and analysis of high-confidence human-machine interfaces. To date, little work has focused on the comparison of these particular types of formal IDEs. This paper compares and evaluates two state-of-the-art toolkits: CIRCUS, a model-based development and analysis tool based on Petri net extensions, and PVSio-web, a prototyping toolkit based on the PVS theorem proving system.This work is partially supported by: Project NORTE-01-0145-FEDER-000016, financed by the North Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, and through the European Regional Development Fund (ERDF); Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) PhD scholarship

Game development as a pedagogical mechanism: a report on an experiment in public schools aimed at sustainability and the protection of the environment .

Educational games have been designed in this study with the aim ofarousing an interest in environmental education among 5th grade student , whichinvolve making sustainable use of the river that flows through the municipality ofInhangapi, located in the North-East of Para State´. The students’ gain inknowledge regarding the subjects covered in class was assessed at the end of thestudents´ game activities that involved the subjects taught. The results showed thatthe use of game construction contributed to the teaching and learning process withregard to the concepts of Computing and environmental education because almost60 % of the students correctly applied what they had been taught about gameconstruction

Indicadores de saúde entre idosos ativos e insuficientemente ativos residentes em áreas rurais

Modelo do estudo: Estudo transversal. Objetivo do estudo: Analisar a associação entre indicadores de saúde em idosos ativos e insuficientemente ativos. Metodologia: Estudo realizado em indivíduos com 60 anos ou mais, residentes na área rural de Jequié – BA, Brasil, cadastrados no programa Estratégia Saúde da Família do distrito de Itajurú. Foram analisadas as características sociodemográficas, comportamentais, estado de saúde, histórico de quedas, estado cognitivo e Índice de Massa Corporal (IMC). Para análise dos dados, utilizaram-se procedimentos da estatística descritiva, testes Qui-quadrado, teste “t” para amostras independentes e U de Mann-Whitney (nível de significância utilizado pd”0,05). Resultados: Foram entrevistados 95 idosos, sendo 55 mulheres e 40 homens com idade entre 60 e 96 anos (73,5 ± 9,4). A prevalência de inatividade física foi de 40%, mostrando-se superior entre os idosos que relataram viver sozinho, que apresentaram déficit cognitivo, que não sabiam ler e escrever, e com histó- rico de quedas no último ano. Os idosos mais jovens e com menor IMC eram mais ativos, quando comparados com seus pares. Conclusão: Os idosos que não alcançaram as recomendações de níveis adequados de atividade física apresentaram condições de saúde mais desfavoráveis. Recomenda-se a implementação de políticas públicas para promoção da atividade física no intuito de melhorar as condi- ções de saúde, em especial os idosos residentes de áreas ruraisStudy design: cross-sectional study. Study objective: To examine the association between health indicators in active and insufficiently active older adults. Methodology: The study included individuals 60 years or older residing in rural Jequie - BA who were registered in the Family Health Strategy program in the district Itajurú. Sociodemographic data, behavioral characteristics, health status, history of falls, cognitive status and body mass index (BMI) were analyzed. For data analysis, we used the procedures of descriptive statistics, chi-square tests, “t” test for independent samples and the Mann-Whitney test (significance level p ≤0.05). Results: Ninety-five individuals were interviewed, including 55 women and 40 men between the ages of 60 and 96 years (73.5 ± 9.4).The prevalence of physical inactivity was 40%, being higher among the elderly who live alone reported that patients with cognitive impairment, who could not read and write with a history of falls in the last year. The older people with lower BMI were more active compared to their peers. Conclusion: The elderly who not reached the recommended adequate levels of physical activity had health conditions more unfavorable. We recommend the implementation of public policies to promote physical activity in order to improve health conditions, especially the elderly residents of rural area

Tratamento de esgoto de uma unidade de ensino superior por meio de um sistema de zona de raízes

O uso de plantas no tratamento de águas residuais é uma alternativa eficiente, sustentável e de baixo custo em comparação ao tratamento convencional. Este estudo teve como objetivo avaliar a eficiência do sistema de zona de raiz em um tratamento de esgoto sanitário, para as condições climáticas de Goiânia-GO, Brasil. Para isso, foi construída uma estação de tratamento experimental na Escola de Engenharia Civil, da Universidade Federal de Goiás (EEC / UFG), consistindo de uma fossa séptica, filtro anaeróbio e três camaras biológica de zona de raiz, em paralelo, usando areia e brita zero e brita número um, respectivamente, como substrato. O sistema foi eficiente na remoção de DBO (98,5%), DQO (95,8%) e coliformes termotolerantes (99,99%)
