Toidentify the occurrence of errors in the use of equipment by nurses working in intensive careandanalyzing them in the framework of James Reason's theory of human error. Qualitative field study in the intensive care unit of a federal hospital in the city of Rio de Janeiro. Observation and interviews were conductedwith eight nurses, from March to December 2014. Content analysis was used for the interviews, as well as the description of the scenes observed. Lapses of memory and attention were identified in the handling of infusion pumps, as well as planning failures during the programming of monitors. Errors cause adverse events that compromise patient safety. The authors propose creation of an instrument for daily checking of equipment, with checks throughout the work process in the programming of infusion pumps and monitors, in order to reduce failures and memory lapses. Identificar a ocorrência de erros na utilização de equipamentos por enfermeiros que atuam na terapia intensiva, analisando-os à luz da teoria do erro humano de James Reason. Pesquisa de campo, qualitativa, na Unidade de Terapia Intensiva de um hospital federal do Rio de Janeiro. Realizou-se observação e entrevista com oito enfermeiros, de março a dezembro de 2014. Aplicou-se análise de conteúdo nas entrevistas e descrição densa nas cenas observadas. Identificaram-se falhas de memória e de atenção no manuseio das bombas infusoras e falhas de planejamento durante a programação dos monitores. Os erros causam eventos adversos que comprometem a segurança do paciente. Propõe-se um instrumento de verificação diária dos equipamentos, com checagens ao longo do processo de trabalho da programação das bombas infusoras e monitores, no intuito de reduzir as falhas e esquecimentos.

Campo de velocidade peculiar na teoria linear

NASA Astrophysics Data System (ADS)

Pires, N.

2003-08-01

Aglomerados e superaglomerados de galáxias são responsáveis pela chamada velocidade peculiar (movimentos relativos à expansão pura do universo) das galáxias. A amplitude destas perturbações depende da densidade de matéria do universo e do contraste de densidade no interior do volume onde está localizada a galáxia. Em 1980, Peebles introduziu o fator "f", que relaciona a amplitude das perturbações da velocidade com o campo gravitacional peculiar, no contexto da teoria linear. No presente trabalho obtemos uma solução geral analítica para o fator "f" de Peebles do campo de velocidades peculiares, em termos de funções hipergeométricas, válida para qualquer geometria do universo. Como um teste de nossa solução, os resultados encontrados originalmente por Peebles em 1980 e os resultados mais gerais encontrados por O. Lahav e colaboradores em 1991, são reobtidos.

Melo, J.; Voelzke, M. R.

2008-09-01

O objetivo principal deste trabalho é procurar desenvolver o interesse dos alunos pelas ciências através da Astronomia. Uma pesquisa com perguntas sobre Astronomia foi realizada junto a 161 alunos do Ensino Fundamental, com o intuito de descobrir conhecimentos prévios dos alunos sobre o assunto. Constatou-se, por exemplo, que 29,3% da 6ª série responderam corretamente o que é eclipse, 30,0% da 8ª série acertaram o que a Astronomia estuda, enquanto 42,3% dos alunos da 5ª série souberam definir o Sol. Pretende-se ampliar as turmas participantes e trabalhar, principalmente de forma prática com: dimensões e escalas no Sistema Solar, construção de luneta, questões como dia e noite, estações do ano e eclipses. Busca-se abordar, também, outros conteúdos de Física tais como a óptica na construção da luneta, e a mecânica no trabalho com escalas e medidas, e ao utilizar uma luminária para representar o Sol na questão do eclipse, e de outras disciplinas como a Matemática na transformação de unidades, regras de três; Artes na modelagem ou desenho dos planetas; a própria História com relação à busca pela origem do universo, e a Informática que possibilita a busca mais rápida por informações, além de permitir simulações e visualizações de imagens importantes. Acredita-se que a Astronomia é importante no processo ensino aprendizagem, pois permite a discussão de temas curiosos como, por exemplo, a origem do universo, viagens espaciais a existência ou não de vida em outros planetas, além de temas atuais como as novas tecnologias.

To verify the correlation between temperature measurements performed using an infrared tympanic thermometer and an esophageal thermometer during the intraoperative period. A longitudinal study of repeated measures was performed including subjects aged 18 years or older undergoing elective oncologic surgery of the digestive system, with anesthesia duration of at least 1 hour. Temperature measurements were performed simultaneously by a calibrated esophageal thermometer and by a calibrated infrared tympanic thermometer, with laboratory reading precision of ±0.2ºC. The operating room temperature remained between 19 and 21ºC. The study included 51 patients, mostly men (51%), white (80.4%). All patients were kept warm by a forced-air heating system, for an average of 264.14 minutes (SD = 87.7). The two temperature measurements showed no different behavior over time (p = 0.2205), however, tympanic measurements were consistently 1.24°C lower (p<0.0001). The tympanic thermometer presented reliable results but reflected lower temperatures than the esophageal thermometer. Verificar a correlação entre as medidas de temperatura realizadas por meio de um termômetro timpânico por infravermelho e por um termômetro esofágico, durante o período intraoperatório. Realizou-se um estudo longitudinal, de medidas repetidas, incluindo sujeitos com idade igual ou superior a 18 anos, submetidos à cirurgia oncológica eletiva do sistema digestório, com duração da anestesia de, no mínimo, 1 hora. As medidas de temperatura eram realizadas, ao mesmo tempo, por meio de um termômetro esofágico calibrado e por termômetro timpânico por infravermelho calibrado, com precisão de leitura em laboratório de ±0,2ºC. A temperatura da sala operatória permaneceu entre 19 e 21ºC. Foram incluídos 51 pacientes, em sua maioria homens (51%), brancos (80,4%). Todos os pacientes foram aquecidos com o sistema de ar forçado aquecido, em média por 264,14 minutos (DP = 87,7). As duas medidas de temperatura não tiveram comportamento diferente ao longo do tempo (p = 0,2205), mas a medida timpânica foi consistentemente menor em 1,24°C (p < 0,0001). O termômetro timpânico apresentou resultados confiáveis, mas refletiu temperaturas mais baixas do que o termômetro esofágico.

To analyze the development of professional skills in an obstetric nursing graduate course. Qualitative research, applying semi-structured interviews with 11 students in the obstetric nursing specialization at the State University of Ceará. Data was submitted to thematic review. According to the subjects, the course offers the development of skills to strengthen and expand the range of activities in obstetric nursing. Despite relying on previous knowledge and experience acquired by the students, there is a gap between the content taught and internship practice, presented as challenges and difficulties faced by the students. The findings suggest a need for curricular revision, incorporating active teaching-learning methodologies, to overcome the disjunction between theory and practice. Students are part of a corpus that is potentially implicated in the construction and transformation of thoughts and values set forth by educational and health institutions, and it is necessary to make changes in political and social organizations, with a focus on providing comprehensive and egalitarian care to the population. Analisar o desenvolvimento de competências profissionais em curso de pós-graduação em Enfermagem Obstétrica. Pesquisa qualitativa, utilizando entrevista semiestruturada com 11 egressos da especialização em Enfermagem Obstétrica da Universidade Estadual do Ceará. Dados submetidos à análise temática. Na ótica dos sujeitos, o curso confere o desenvolvimento de competências que fortalecem e ampliam o campo de atuação da enfermagem obstétrica. Embora resgate o conhecimento prévio dos discentes e as experiências vivenciadas, há distanciamento entre conteúdos ministrados e a prática de estágios, apresentados como desafios e dificuldades enfrentadas pelos egressos. Os achados sugerem revisão curricular, incorporando as metodologias ativas de ensino-aprendizagem, superando a fragmentação entre teoria e prática. Os egressos se constituem em um corpus potencialmente implicado na construção e transformação de pensamentos e valores das instituições de saúde e ensino, necessários às mudanças nas organizações políticas e sociais, visando atendimento integral e igualitário à população.

Determinação de elementos próprios dos asteróides troianos: comparação entre as teorias semi-analítica e sintética

NASA Astrophysics Data System (ADS)

Roig, F.; Beaugé, C.

2003-08-01

Além do cálculo semi-analítico de elementos próprios dos asteróides Troianos (Beaugé & Roig 2001, Icarus 153, 391), recentemente foi apresentado um novo conjunto destes elementos próprios determinado através de uma teoria sintética (Knenezevic & Milani 2003, comunicação pessoal). As bases de dados contendo estas determinações estão disponiveis na pagina web do Asteroid Dynamical Site (http://hamilton.dm.unipi.it/cgi-bin/astdys/astibo). Nesta comunicação apresentamos os primeiros resultados de um estudo comparativo entre ambos conjuntos de elementos próprios, analisando suas vantagens e desvantagens, assim como os limites de precisão de cada conjunto. Mostramos que os elementos próprios sintéticos são mais precisos que os smi-analíticos para grandes amplitudes de libração do ângulo s = l-lJup, embora acontece o contrario para os corpos cuja amplitude de libração é muito pequena. Finalmente discutimos a influencia destes erros na determinação de familias de asteroides e da estrutura resonante em torno dos pontos Lagrangeanos L4 e L5.

Confidence Intervals for Omega Coefficient: Proposal for Calculus.

La confiabilidad es entendida como una propiedad métrica de las puntuaciones de un instrumento de medida. Recientemente se viene utilizando el coeficiente omega (ω) para la estimación de la confiabilidad. No obstante, la medición nunca es exacta por la influencia del error aleatorio, por esa razón es necesario calcular y reportar el intervalo de confianza (IC) que permite encontrar en valor verdadero en un rango de medida. En ese contexto, el artículo plantea una forma de estimar el IC mediante el método de bootstrap para facilitar este procedimiento se brindan códigos de R (un software de acceso libre) para que puedan realizarse los cálculos de una forma amigable. Se espera que el artículo sirva de ayuda a los investigadores de ámbito de salud.

Perfis de temperatura eletrônica em regiões HII

Copetti, M. V. F.

2003-08-01

As flutuações de temperatura eletrônica em regiões HII, inicialmente propostas para explicar as discrepâncias entre os valores de temperatura obtidos por diferentes métodos, têm sido apontadas como a causa mais provável das enormes diferenças encontradas entre as abundâncias químicas medidas através de linhas excitadas colisionalmente e de linhas de recombinação. Recentemente têm sido reportadas tentativas de detecção e quantificação diretas das flutuações de temperatura eletrônica através de medidas ponto a ponto, obtidas por meio de espectroscopia de fenda longa, das razões de linhas [OIII]l4263/l5007 e [NII]l5755/l6584, principais sensores de temperatura. Neste trabalho, utilizamos o código numérico de fotoionização Cloudy para avaliar a confiabilidade desse procedimento. Concluímos que, para valores de densidade eletrônica e de temperatura efetiva da estrela ionizante típicos das regiões HII, os perfis superficiais de temperatura obtidos via medidas do sensor [OIII]l4263/l5007 são bons traçadores dos gradientes internos de temperatura eletrônica. Já os perfis de temperatura eletrônica medidos por meio da razão [NII]l5755/l6584 não reproduzem os gradientes verdadeiros de temperatura.

To characterize the Brazilian workers victims of occupational accidents with biological fluids. Epidemiological and descriptive research, in which 284,877 notifications of the Notifiable Diseases Information System were analyzed between 2007 and 2014. We used Stata 13 for data analysis. The highest incidence density occurred in females with 0.8 cases per 1,000 workers/year (n = 222,042, 77.9%); in the age group of 20 to 24 years old, with 0.6 cases per 1,000 workers/year (n = 64,221, 23.3%); with some high school and some college, with 0.6 cases per 1,000 workers/year (n = 141,275, 49.6%). We found that these accidents occurred among 23 occupational subgroups. For the most part, the workers had an employment relationship and had issued the Occupational Accident Notification. It is necessary to rethink the measures of orientation to workers regarding the risks and relative prophylaxis for these accidents, with the aim of reducing them. Caracterizar os trabalhadores brasileiros vítimas de acidente de trabalho com fluidos biológicos. Pesquisa epidemiológica, descritiva, na qual foram analisadas 284.877 notificações do Sistema Nacional de Notificação de Agravos, entre 2007 e 2014. Utilizou-se Stata 13 para a análise dos dados. A maior densidade de incidência ocorreu no sexo feminino com 0,8 caso a cada 1.000 trabalhadores/ano (n = 222.042; 77,9%); na faixa etária de 20 a 24 anos com 0,6 caso a cada 1.000 trabalhadores/ano (n = 64.221; 23,3%); com Ensino Médio e Superior incompleto com 0,6 caso a cada 1.000 trabalhadores/ano (n = 141.275; 49,6%). Verificou-se que esses acidentes ocorreram entre 23 subgrupos ocupacionais. Em sua maioria, os trabalhadores possuíam vínculo empregatício e tiveram emitida a Comunicação de Acidente de Trabalho. Faz-se necessário repensar as medidas de orientação aos trabalhadores quanto aos riscos e profilaxia relativa para estes acidentes, visando reduzi-los ou diminui-los.

To evaluate the quality of life of physicians and investigate to what extent it is affected by work addiction. This is an exploratory, descriptive and cross-sectional study, conducted with 1,110 physicians. For data collection, we used a questionnaire with sociodemographic information, the World Health Organization Quality of Life BREF, and the Work Addiction Scale. Most physicians presented high quality of life. Female participants presented lower quality of life in the domains psychologic, environment and general (p<0.05). Quality of life was negatively correlated with the number of shifts (p<0.005). The higher the addiction to work, the lower the quality of life. The research allowed understanding the implications of work addiction in the quality of life. Further studies are required to support the development of strategies that improve health conditions and quality of life of medical professionals. Avaliar a qualidade de vida de médicos e investigar em que medida a adição ao trabalho a afeta. Trata-se de um estudo exploratório, descritivo e transversal, realizado com 1.110 médicos. Para coleta de dados, optou-se por utilizar um questionário contendo informações sociodemográficas, bem como aplicar o instrumento World Health Organization Quality of Life-BREF e a Escala de Adição ao Trabalho. Os médicos, em sua maioria, apresentaram alta qualidade de vida. Os participantes do sexo feminino tiveram menor qualidade de vida em relação aos homens nos domínios psicológico, meio ambiente e geral (p<0,05). A qualidade de vida correlacionou-se negativamente com o número de plantões (p<0,005), e quanto maior a adição ao trabalho, menor a qualidade de vida. A pesquisa permitiu o conhecimento das implicações da adição ao trabalho sobre a qualidade de vida. Novos estudos são necessários para subsidiar a elaboração de estratégias que melhorem a saúde e a qualidade de vida do profissional médico.

To analyze the use of methodological strategies in qualitative research - Minimum Maps of Social Institutional Network, as proposed to understand the phenomena in the multidimensional perspective. Methodological theoretical essay in which we aimed to reflect on the use of innovative methodological strategies in nursing research, supported in Complex Paradigm fundamentals. The minimum map of Social Institutional External Network aims to identify institutional linkages and gaps for the intervention work of the surveyed institutions. The use of these maps provided important advances in know-how qualitative research in Health and Nursing. In this perspective, the use of minimum Social Intitutional Network maps can be stimulated and enhanced to meet the current demands of the contemporary world, particularly for its flexibility in adapting to various research subjects; breadth and depth of discussion; and possibilities with health services.

Résumé.L'étude de dispositifs de dénoyage est nécessaire pour l'amélioration de sites avant la construction de certaines structures. L'étude de dispositifs de dénoyage efficaces exige d'estimer la valeur du coefficient de perméabilité in situ. Les relations disponibles pour estimer le coefficient de perméabilité ont été développées sur la base de mesures et de conditions de terrain limitées, et les prédictions varient de plusieurs ordres de grandeur. C'est pourquoi il est nécessaire de réaliser des mesures de perméabilité sur le terrain et de déterminer la relation qui permet le meilleur ajustement de ces mesures avant l'étude du dispositif de dénoyage pour des conditions locales et géologiques spécifiques. Ce papier présente des mesures de perméabilité sur le terrain dans des niveaux calcaires complexes chaotiques et diagénétisés. Il propose également une analyse comparative de plusieurs relations disponibles dans la littérature destinées à prédire le coefficient de perméabilité in situ. L'analyse est faite en conditions permanentes et non permanentes. Les résultats montrent que la valeur du coefficient de perméabilité dépend du niveau de la nappe, qui est affecté par le régime de marées. On montre que l'équation de l'US Navy donne la meilleure corrélation avec les mesures de terrain. Resumen.El diseño de sistemas de desecado es necesario para mejorar las condiciones de un emplazamiento antes de la construcción de determinadas estructuras. El diseño de un sistema eficiente de desecado requiere de la estimación del valor de la permeabilidad in-situ. Las relaciones disponibles para tal fin han sido desarrolladas bajo condiciones y medidas de campo limitadas; sus predicciones varían en algunos órdenes de magnitud. Por tanto, es necesario tomar medidas de permeabilidad en campo y determinar la relación que reproduce mejor dichas medidas como paso previo al diseño de un sistema de desecado en condiciones geológicas y de emplazamiento específicas. Este artículo presenta medidas de permeabilidad en campo para estratos de calcita caóticos y diagenéticos. También ofrece un análisis comparativo de diversas relaciones disponibles en la bibliografía con el fin de predecir el valor de la permeabilidad in-situ. El análisis se ha hecho tanto en régimen permanente como en estacionario. Los resultados demuestran que la permeabilidad depende del nivel freático, el cual está afectado por las mareas. La ecuación de la Marina estadounidense es la que proporciona una mejor correlación con las medidas de campo.

Segura Garcia, Jaume

La contaminacion ambiental por campos electromagneticos ha resultado ser en estos ultimos anos uno de los problemas mas acuciantes del panorama tecnologico y de salud publica. En el primero de los casos porque las inversiones realizadas son enormes y en el segundo porque cada vez es mayor el numero de articulos, "technical reports" e informes medicos que afirman la existencia de una cierta causalidad, aunque sea debil, entre los campos electromagneticos y ciertos cuadros sintomatologicos. En nuestro caso, hemos dedicado bastantes esfuerzos a investigar el llamado "sindrome de radiofrecuencia / microondas", denominado asi en la literatura cientifica por presentarse en operarios de estaciones de radar y en trabajadores de potentes emisoras de radio y television. En esta memoria presentamos un resumen del trabajo realizado durante los ultimos anos en la medida de la contaminacion electromagnetica ambiental asociado a las comunicaciones inalambricas. En ella se recogen los fundamentos fisicos y propiedades de las ondas electromagneticas, la tecnologia empleada en los sistemas de telefonia celular y los antecedentes relativos a la investigacion de la interaccion de las ondas electromagneticas con organismos vivos. Se desarrolla un procedimiento de medida que ha conducido a la elaboracion de los primeros "mapas de radiofrecuencia" similares, en el aspecto descriptivo, a los mapas de ruido desarrollados en el area de la contaminacion acustica. Por ultimo, se analiza la respuesta subjetiva de los residentes, personas que viven en el entorno de cobertura de las estaciones base de telefonia movil y que se ven sometidos a determinados niveles de radiacion electromagnetica, con el fin de situar este fenomeno al nivel que le corresponde en el ambito de la respuesta subjetiva ciudadana.

Evolução temporal de discos circunstelares em estrelas Be

NASA Astrophysics Data System (ADS)

Fernandes, M. V. M.; Leister, N. V.; Levenhagen, R. S.

2003-08-01

A pesquisa do mecanismo que leva uma estrela do tipo Be a perder massa e formar um envelope circunstelar, nomeado como fenômeno Be, é uma questão em aberto, intrigante, e que adquire contornos interessantes em face às informações espectroscópicas de alta resolução. Nesta última década, consolida-se a idéia de que a forma destes envelopes é de tipo discóide, obedecendo a uma lei Kepleriana de velocidades, e mais ainda, recentemente há evidências de que a distribuição de matéria nestes discos pode assumir um caráter de anel. Medidas de algumas dimensões de discos circunstelares puderam ser obtidas pela análise de espectros de alta resolução e alta relação sinal-ruído para as estrelas Be: alpha Eri (HD 10144, B3Vpe), omicron And (HD 217675, B6IIIpe), e eta Cen (HD el972, B1.5Vne), no período dos anos de 1991 a 2001. Alguns modelos clássicos de envelope predizem uma distribuição de massa que decresce suavemente a partir da superfície estelar. Entretanto, considerando que a separação de picos de emissão em perfis de linhas do HeI e H-alpha, alargados por efeitos cinemáticos, é função do raio estelar e da velocidade rotacional projetada (vsini); nossos resultados sugerem a presença de um anel de matéria circunstelar, que aparece logo após a ejeção do material fotosférico, imediatamente acima da superfície estelar, e que se expande para raios maiores ao longo do tempo, eventualmente desconectando-se da superfície por uma região de densidade de matéria mínima. Tais interpretações revivem a idéia de que anéis de matéria circunstelar podem ser os responsáveis por algumas variabilidades em perfis de linhas de emissão, como as variações V/R.

É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite otimizar a divulgação e o ensino não formal de Astronomia aliando a adequação do conteúdo à expectativa das pessoas. Nesse intuito, nosso trabalho busca mapear que assuntos da Astronomia despertam mais a atenção e o interesse das pessoas e o quanto disso é estimulado pela mídia, que freqüentemente aproveita-se desse interesse de forma sensacionalista, trazendo contribuições positivas e negativas. Para esta avaliação, utilizamos as pesquisas específicas e de caracterização do público que freqüentou o MAst nos anos de 2001 a 2003, pesquisa das matérias de Astronomia veiculadas na mídia escrita da cidade do Rio de Janeiro no mesmo período, além da base de dados do programa Pergunte a um astrônomo, realizado no Observatório Nacional nos anos de 1997 a 1999. Para a análise dos dados, dividimos as perguntas em dez categorias, cada uma com suas subcategorias, tomando como referência as divisões, comissões e grupos de trabalho da IAU. Apresentamos neste trabalho os resultados dessa pesquisa, que incluem, entre outros, a predominância de questões nas categorias Observação do Céu e Sistemas Planetários enquanto nos jornais dominam as notícias de Sistemas Planetários e Espaço & Astronáutica. Outro resultado interessante indicou que as dúvidas de crianças do ensino fundamental se concentram em algumas categorias enquanto as questões de adultos são mais distribuídas por todas as categorias. Os resultados dessa pesquisa serão aplicados diretamente no aperfeiçoamento das atividades do Programa de Observação de Céu, bem como na elaboração de novos projetos e eventos realizados no MAst.

Avaliação do conhecimento de pacientes diabéticos sobre medidas preventivas do pé diabético em Maringá (PR)

2017-01-01

Resumo Contexto O atual envelhecimento da população tem gerado maior predominância de doenças crônicas, como o diabetes, a qual está associada a um risco elevado de complicações crônicas e agudas. Entre essas, o pé diabético (PD) destaca-se por possuir alta incidência e grande poder mutilador. Objetivo Avaliar o conhecimento da população diabética das Unidades Básicas de Saúde (UBS) de Maringá (PR) sobre a prevenção do PD. Métodos Estudo descritivo, quantitativo, tipo inquérito por entrevista. A população estudada foi composta por 80 portadores de diabetes, cadastrados em UBS de Maringá (PR). A coleta de dados buscou levantar dados sociodemográficos e epidemiológicos, bem como as atitudes de controle do diabetes e do autocuidado para prevenção do PD. Resultados Do total de entrevistados, nove não realizavam qualquer tipo de exame para controle do diabetes e a renda mensal predominante foi de até um salário mínimo. O grau de escolaridade e a renda mensal não se mostraram relevantes em relação ao conhecimento de cuidados preventivos do PD e nem uma maior adesão a hábitos de vida saudáveis. O cuidado com o PD tende a melhorar à medida que exista uma compreensão mais clara dos fatores que conduzem à perda do membro e um crescente consenso sobre a gestão de vários aspectos clínicos do cuidado com o pé. Conclusão Existe uma falta de aprendizado das medidas preventivas, mesmo nos pacientes com algum nível de instrução, o que induz a uma prática deficiente de cuidados.

To socialize an educational action through the process of group discussion and reflection, with the aim to increase the care of nursing workers in facing occupational risks. A qualitative descriptive study using the Convergent Care Research modality with nursing staff working in an emergency department of a hospital in the northwest region of the state of Rio Grande do Sul, Brazil. Data collection was carried out through educational workshops and information was processed using content analysis, resulting in two thematic categories: A look at the knowledge and practices about occupational risks in nursing; and adherence to protective measures by the nursing team against occupational risks. Twenty-four (24) workers participated in the study. When challenged to critically look at their actions, the subjects found that they relate the use of safety devices to situations in which they are aware of the patient's serological status. Subjects' interaction, involvement and co-responsibility in the health education process were determinant for their reflection on risky practices. They also had the potential to modify unsafe behaviors. Socializar uma ação educativa, por meio de um processo de discussão e reflexão em grupo, com vistas a ampliar o cuidado dos trabalhadores de enfermagem frente aos riscos ocupacionais. Estudo qualitativo, descritivo na modalidade Pesquisa Convergente Assistencial, com trabalhadores da equipe de enfermagem que atuavam no pronto atendimento de um hospital da região noroeste do estado do Rio Grande do Sul. A coleta de dados foi realizada por meio de oficinas educativas, e o tratamento das informações, por análise de conteúdo, resultando em duas categorias temáticas: Um olhar direcionado a saberes e práticas sobre riscos ocupacionais na enfermagem e Adesão às medidas de proteção pela equipe de enfermagem frente aos riscos ocupacionais. Integraram o estudo 24 trabalhadores. Ao serem desafiados a olhar criticamente sobre seu fazer, os sujeitos constataram que vinculam o uso dos dispositivos de segurança a situações em que conhecem o status sorológico do paciente. A interação, o envolvimento e a corresponsabilização dos sujeitos no processo de educação em saúde foram determinantes para a reflexão das práticas de risco, bem como tiveram potencial para modificar comportamentos inseguros. Socializar una acción educativa a través de un proceso de discusión y reflexión grupal, con el fin de ampliar el cuidado de los trabajadores de enfermería en relación a los riesgos ocupacionales. Estudio cualitativo, descriptivo en modalidad de Investigación Convergente Asistencial, con trabajadores del equipo de enfermería que actuaban en el servicio de urgencia de un hospital de la región noroeste del estado de Rio Grande del Sur. La recolección de datos se realizó a través de talleres educativos y el tratamiento de las informaciones por análisis de contenidos, lo que resultó en dos categorías temáticas: una mirada dirigida a los saberes y las prácticas relacionadas a riesgos ocupacionales y la adhesión a las medidas de protección por el equipo de enfermería para los riesgos ocupacionales. El estudio incluyó 24 trabajadores a los que cuando se presentó el desafío de observar su críticamente sus acciones, constataron que relacionan el uso de los dispositivos de seguridad a las situaciones en que el status serológico de los pacientes es ya conocido. La interacción, el involucramiento y la corresponsabilidad de los sujetos en el proceso de educación en salud son determinantes para la reflexión sobre las practicas riesgosas y tienen potencial para modificar comportamientos inseguros.

The convenience sample was composed by a hundred and twenty one senior caregivers (Avg=70.5 ± 7.2 years, 73% women). They answered a questionnaire to check the physical and cognitive demands of care, the Zarit Burden Interview (ZBI), the California Inventory of Coping Strategies and the Geriatric Depression Scale (GDS-15). ZBI showed good internal consistency and also for the three factors emerging from factor analysis, explaining 44% of variability. ZBI is positively related with objective care demands (p < 0.001), depression (p = 0.006) and use of dysfunctional coping strategies (p = 0.0007). ZBI is of interest to be applied to aged caregivers and the association of higher degrees of burden, dysfunctional coping and depression show a vulnerability scenario that may affect to older people taking care of other elderly. derivar indicadores psicométricos de validade de construto e consistência interna da escala de sobrecarga de cuidadores de Zarit Burden Interview e descrever associações desta com medidas referentes às demandas de cuidado, estratégias de enfrentamento e depressão em cuidadores idosos. estudo descritivo, transversal e correlacional.

Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

Hypertension is an important risk factor for cardiovascular outcomes. Primary health care (PHC) physicians should be prepared to act appropriately in the prevention of cardiovascular risk factors. However, the rates of patients with control of blood pressure (BP) remain low. The impact of the reclassification of high BP by 24-hour ambulatory BP monitoring (ABPM) can lead to different medical decisions in PHC. To evaluate the agreement between the BP measured by a conventional method by PHC physicians and by 24-hour ABPM, considering different BP normal thresholds for the 24-hour ABPM according to the V Brazilian ABPM Guidelines and the European Society of Hypertension Guidelines. A cross-sectional study including 569 hypertensive patients. The BP was initially measured by the PHC physicians and, later, by 24-hour ABPM. The BP measurements were obtained independently between the two methods. The therapeutic targets for the conventional BP followed the guidelines by the Eighth Joint National Committee (JNC 8), the V ABPM Brazilian Guidelines, and the 2013 European Hypertension Guidelines. There was an accuracy of 54.8% (95% confidence interval [95%CI] 0.51 - 0.58%) for the BP measured with the conventional method when compared with the 24-hour ABPM, with a sensitivity of 85% (95%CI 80.8 - 88.6%), specificity of 31.9% (95%CI 28.7 - 34.7%), and kappa value of 0.155, when considering the European Hypertension Guidelines. When using more stringent thresholds to characterize the BP as "normal" by ABPM, the accuracy was 45% (95%CI 0.41 - 0.47%) for conventional measurement when compared with 24-hour ABPM, with a sensitivity of 86.7% (95%CI 0.81 - 0.91%), specificity of 29% (95%CI 0.26 - 0.30%), and kappa value of 0.103. The BP measurements obtained by PHC physicians showed low accuracy when compared with those obtained by 24-hour ABPM, regardless of the threshold set by the different guidelines. A hipertensão arterial sistêmica é um fator de risco importante para desfechos cardiovasculares. Médicos da atenção primária à saúde (APS) devem estar preparados para atuar adequadamente na prevenção de fatores de risco cardiovascular. No entanto, as taxas de pacientes com pressão arterial (PA) controlada continuam baixas. O impacto da reclassificação do diagnóstico de hipertensão pela utilização da monitorização ambulatorial da PA (MAPA) de 24 horas pode levar a diferentes decisões médicas na APS. Avaliar a concordância entre as PAs medidas por método convencional por médicos da APS e por MAPA de 24 horas, considerando diferentes limiares de normalidade para a MAPA de 24 horas de acordo com as recomendações da V Diretriz Brasileira de MAPA e da Diretriz da Sociedade Europeia de Hipertensão. Estudo transversal com 569 pacientes hipertensos. A PA foi medida inicialmente por médicos da APS e, posteriormente, pela MAPA de 24 horas. As medidas foram obtidas de forma independente entre os dois métodos. Os alvos terapêuticos para a PA convencional seguiram as orientações do Eighth Joint National Committee (JNC 8), das V Diretrizes Brasileiras de MAPA e das Diretrizes Europeias de Hipertensão de 2013. Foi observada uma acurácia de 54,8% (intervalo de confiança de 95% [IC95%] 0,51 - 0,58%) para a PA aferida de forma convencional quando comparada à obtida com a MAPA de 24 horas, além de uma sensibilidade de 85% (IC95% 80,8 - 88,6%), especificidade de 31,9% (IC95% 28,7 - 34,7%) e kappa de 0,155, quando consideradas as Diretrizes Europeias de Hipertensão. Quando utilizados limiares mais rígidos para caracterizar a PA como "normal" pela MAPA, foi identificada uma acurácia de 45% (IC95% 0,41 - 0,47%) pela medida convencional quando comparada à obtida pela MAPA de 24 horas, além de uma sensibilidade de 86,7% (IC95% 0,81 - 0,91%), especificidade de 29% (IC95% 0,26 - 0,30%) e kappa de 0,103. As medidas de PA avaliadas pelos médicos da APS apresentaram baixa acurácia quando comparadas às medidas pela MAPA de 24 horas, independente do limiar utilizado pelas diferentes diretrizes.

To understand the meanings of cancer within the experience of rural families and how such meanings influence family dynamics. Qualitative study guided by Symbolic Interactionism as a theoretical framework and Grounded Theory as a methodological framework. Six rural families (18 participants) undergoing the experience of having a relative with cancer participated in the interview. Constant comparative analysis of data allowed the elaboration of an explanatory substantive theory, defined by the main category Caregiving to support the family world, which represents the family's symbolic actions and strategies to reconcile care for the patient and care for family life. Throughout the experience, rural families seek to preserve the interconnected symbolic elements that provide support for the family world: family unit, land, work and care. Compreender os significados do câncer presentes na experiência de famílias rurais e como esses significados influenciam a dinâmica familiar. Estudo qualitativo orientado pelo Interacionismo Simbólico como referencial teórico e pela Teoria Fundamentada nos Dados como referencial metodológico. Participaram, por meio de entrevista, seis famílias rurais (18 participantes) que estavam vivendo a experiência de ter um familiar com câncer. A análise comparativa constante dos dados permitiu a elaboração de uma teoria substantiva explicativa da experiência, definida pela categoria central Cuidando para manter o mundo da família amparado, que representa as ações e estratégias simbólicas da família visando a conciliar o cuidado do familiar doente e o cuidado da vida familiar. Ao longo da experiência, a família rural procura preservar os elementos simbólicos que, conectados, constituem o amparo do mundo da família: a unidade familiar, a terra, o trabalho e o cuidado.

Developing countries have experienced a dramatic increase in the number of clinical studies in the last decades. The aim of this study was to describe 1) the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa) from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs) and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP) in Brazil from 2007 to 2011 and 2) the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1) the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP) and 2) Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC). Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011). Type 2 diabetes (26.0%) and breast cancer (20.5%)-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1) a clear trend toward more research involving human beings in Brazil, 2) good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3) a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

the level and evolution of income inequality among adults in Brazil between 2006 and 2012. to calculate the level of inequality, its trend over the years and the share of income growth appropriated by different social groups. We combined tax data from the Annual Personal Income Tax Returns (Declaração Anual de Ajuste do Imposto de Renda da Pessoa Física - DIRPF) and the Brazilian National Household Survey (Pesquisa Nacional por Amostra de Domicílios - PNAD) to construct a complete distribution of total income among adults in Brazil. We applied Pareto interpolations to income tax tabulations to arrive at the distribution within income groups. We tested the results, comparing the PNAD to the Brazilian Consumption and Expenditure Survey (Pesquisa de Orçamentos Familiares - POF) and to data from the Census Subsample Survey (Census. We found evidence that income inequality in Brazil is higher than previously thought and that it remained stable between 2006 and 2012; in making these findings, we thus diverged from most studies on the dynamics of inequality in Brazil.. There was income growth, but the top incomes have appropriated most of this growth.

This work is presented as a theoretical essay on some facts from the history of astronomy analyzed according to the theory of reflective abstraction developed by Jean Piaget and collaborators (1970). Its aim is to understand the reasons that led to different astronomers, at the same historical period and culture, to "see" quite different evidences about the same phenomenon. In addition, we intend to facilitate the understanding of science as a human construction, subject to a time epoch and the ways of understanding of each scientist. Este trabajo se presenta como un ensayo teórico sobre algunos hechos históricos de la astronomía, analizados según la teoría de la abstracción reflexionante de Jean Piaget y sus colaboradores (1970). Se trata de comprender los motivos que llevaran a distintos astrónomos, de una misma época histórica y cultural, a "ver" diferentes evidencias sobre un mismo fenómeno. Además, se intenta posibilitar la comprensión de la ciencia como construcción humana, la cual es condicionada por su momento histórico y por las creencias y las formas de entender de los científicos. Este trabalho configura-se como um ensaio teórico a respeito de alguns fatos da história da astronomia analisados segundo a teoria da abstração reflexionante elaborada por Jean Piaget e seus colaboradores (1970). Trata-se de compreender os motivos que levaram diferentes astrônomos, da mesma época histórica e cultural, a "enxergarem" evidências tão diferentes sobre um mesmo fenômeno. Além disso, pretendemos possibilitar a compreensão das Ciências como construção humana, condicionadas a uma época e às crenças e os modos de compreender de cada cientista.

A Rede Neural Artificial (RNA), no âmbito da teoria computacional, constitui uma teoria emergente que, por possuir habilidade em aprender a partir de dados de entrada, encontra diferentes aplicações em diferentes áreas. Um exemplo é a utilização de RNA na caracterização de padrões associados à dinâmica de processos espaço-temporais relacionados a fenômenos físicos não-lineares. Para obter informações sobre o comportamento destes fenômenos físicos utiliza-se, em diversos casos, seqüências de imagens digitalizadas, onde a caracterização de alguns fenômenos espaço-temporais é o procedimento mais viável para descrever a dinâmica das regiões ativas do Sol. Com base em imagens observadas por telescópios a bordo de satélites, estudos de previsão de eventos solares podem ser programados, permitindo prever possíveis efeitos posteriores nas regiões mais próximas da Terra (tempestades geomagnéticas e irregularidades ionosféricas). Neste trabalho avaliamos o desempenho da RNA para estimar padrões espaço-temporais, ou seja, imagens solares em ultravioleta, obtidas através do telescópio a bordo do satélite SOHO. Os resultados mostraram que as RNA conseguem generalizar os padrões de maneira satisfatória sem perder de forma significativa os principais aspectos da configuração global da atmosfera solar, comprovando a eficácia da RNA como ferramenta para esse tipo de aplicação. Portanto, este trabalho comprova a viabilidade de uso desta ferramenta em projetos voltados ao estudo do comportamento solar, em trabalhos do grupo de Física do Meio Interplanetário (FMI) na DAS e em programas desenvolvidos pelo Núcleo de Simulação e Análise de Sistemas Complexos (NUSASC) do Laboratório Associado de Computação e Matemática Aplicada (LAC) do INPE.

Assess the content validity of the Elderly Health Assessment Tool with low education. The data collection instrument/questionnaire was prepared and submitted to an expert panel comprising four healthcare professionals experienced in research on epidemiology of aging. The experts were allowed to suggest item inclusion/exclusion and were asked to rate the ability of individual items in questionnaire blocks to encompass target dimensions as "not valid", "somewhat valid" or "valid", using an interval scale. Percent agreement and the Content Validity Index were used as measurements of inter-rater agreement; the minimum acceptable inter-rater agreement was set at 80%. The mean instrument percent agreement rate was 86%, ranging from 63 to 99%, and from 50 to 100% between and within blocks respectively. The Mean Content Validity Index score was 93.47%, ranging from 50 to 100% between individual items. The instrument showed acceptable psychometric properties for application in geriatric populations with low levels of education. It enabled identifying diseases and assisted in choice of strategies related to health of the elderly. Avaliar a validade de conteúdo do Instrumento de Avaliação da Saúde do Idoso com baixa escolaridade. Após a elaboração do instrumento de coleta de dados, o questionário foi submetido à avaliação de um comitê de especialistas, formado por quatro profissionais da área da saúde com experiência em pesquisas da epidemiologia do envelhecimento. Os especialistas puderam sugerir questões a serem incluídas/excluídas do instrumento, e avaliar cada bloco do questionário, observando se as dimensões a serem avaliadas foram abrangidas pelos itens do instrumento, em escala intervalar, como "não válida", "pouco válida" e "válida". Como medidas para avaliar o grau de concordância do instrumento, foram utilizados o porcentual de concordância e o Índice de Validade de Conteúdo. Considerou-se uma taxa aceitável de concordância o valor de 80%. O instrumento apresentou taxa média de concordância de 86%, variando, dentre os blocos, de 63 a 99% e, dentre os itens, de 50 a 100%. O Índice de Validade de Conteúdo apresentou escore médio de 93,47% e, dentre os itens do questionário, de 50 a 100%. O instrumento apresentou qualidades psicométricas aceitáveis para ser utilizado entre a população de idosos com baixa escolaridade, permitindo a identificação dos agravos e auxiliando na escolha de estratégias, no que diz respeito à saúde do idoso.

A história da física contemporânea é pródiga em grandes descobertas (a Relatividade e a Mecânica Quântica entre as mais importantes) até meados dos anos '30. O peso destes desenvolvimentos é tão grande que outros feitos de grande porte (por exemplo, a teoria da nucleossíntese nas estrelas) são geralmente considerados como "filhotes" dos primeiros, ao menos na imaginação popular. Porém, algumas exceções à regra não-escrita são dignas de menção. Entre estas últimas está a descoberta por S.W.Hawking e colaboradores das propriedades de emissão dos buracos negros, trabalho que iniciou uma disciplina com vida própria denominada Termodinâmica de Buracos Negros.

The purposes of this study were to examine (a) differences in spiritual perspectives and practices of Latino and non-Latino young adults and (b) the cultural relevance of the Latino Spiritual Perspective Scale (LSPS). Studies indicate that spiritual perspectives are embedded within cultural group norms and vary significantly across ethnic groups. A cross-sectional survey design was used with a convenience sample of 223 Latino and non-Latino university students in the Southwestern United States. The Spiritual Perspective Scale (SPS), the LSPS, the Orthogonal Cultural Identification Scale, and a demographic questionnaire were used. Latinos scored significantly higher than non-Latinos in both measures of spiritual perspectives. Self-reported behavioral measures, such as frequency of personal prayer, were also higher among the Latino group. Latino cultural identification was the only significant predictor of LSPS scores. Findings from this study indicate that spirituality among Latinos has meanings specific to the cultural group context. These findings have implications for nursing research involving the conceptualization and measurement of spirituality among multiethnic groups. Los propósitos de este estudio eran examinar: (a) diferencias en perspectivas espirituales y prácticas de jóvenes Latinos y no Latinos; y (b) la relevancia cultural de la Escala de la Perspectiva Espiritual Latina. Estudios indican que perspectivas espirituales están incrustadas entre normas culturales del grupo y varían considerablemente entre grupos étnicos. Un diseño transversal y de encuesta fue utilizado con una muestra de conveniencia de 233 estudiantes universitarios Latinos y no Latinos en el Suroeste de los Estados Unidos. La Escala de la Perspectiva Espiritual (EPE), la Escala de la Perspectiva Espiritual Latina (EPEL), la Escala Ortogonal de Identificación Cultural, y un cuestionario demográfico fueron utilizados. Los Latinos calificaron considerablemente más alto que los no Latinos en ambas medidas de perspectivas espirituales. Medidas de comportamiento auto-reportadas, como la frecuencia de oración, también estuvieron más altas en el grupo Latino. La identificación con la cultura Latina fue el único vaticinador de las calificaciones de la EPEL. Los resultados de este estudio indican que la espiritualidad entre Latinos tiene significados específicos al contexto del grupo cultural. Estas conclusiones tienen implicaciones para las investigaciones de enfermería que involucran la conceptualización y medida de la espiritualidad entre grupos multiétnicos. PMID:20165566

Voelzke, Marcos Rincon; Gonzaga, Edson Pereira

2011-12-01

A razão para o desenvolvimento deste trabalho baseia-se no fato de que muitos professores da Educação Básica (EB) não lidam com conceitos relacionados à astronomia, e quando o fazem eles simplesmente seguem livros didáticos que podem conter erros conceituais. Como é de conhecimento geral a astronomia é um dos conteúdos a serem ensinados na EB fazendo parte dos Parâmetros Curriculares Nacionais e das Propostas Curriculares do Estado de São Paulo, mas é um fato, que vários pesquisadores apontam, a existência de muitos problemas no ensino da astronomia. Com o propósito de minimizar algumas dessas deficiências foi realizado um trabalho de pesquisa com a utilização de questionários pré e pós pesquisa, para tanto foi desenvolvido um Curso de Extensão Universitária para professores da Diretoria de Ensino Regional (DE) que abrange Mauá, Ribeirão Pires e Rio Grande da Serra (no Estado de São Paulo) com os seguintes objetivos: levantar concepções alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem após o curso, adotando-se como referência, para a análise dos resultados, os dicionários de Língua Portuguesa (FERREIRA, 2004) e Enciclopédico de Astronomia e Astronáutica (MOURĀO, 1995). Portanto, dezesseis questões foram aplicadas antes e após o curso, assim pode-se verificar após a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar é composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstício, 72,7% sabiam como explicar a ocorrência das estações do ano; 64,5% explicaram corretamente a ocorrência do equinócio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram asteróide, 54,5% meteoro, 58,1% galáxia, e 42,4% planeta. Os resultados obtidos indicam uma aprendizagem significativa por parte dos participantes.

A atuação do Observatório Nacional registrada nos relatórios ministeriais 1889 a 1930

Rodrigues, T.

2003-08-01

O período republicano até 1930 foi marcante na história do Observatório Nacional. Diversas reformas levaram a instituição a três ministérios diferentes e mudaram a ênfase do seu trabalho. A tão aguardada mudança para uma nova sede, em São Cristóvão, em 1920, não foi suficiente para que a instituição acompanhasse o ritmo tomado pela astronomia no mundo e se firmasse como ambiente de pesquisa. Uma análise simplificada poderia caracterizar um período de produção científica insignificante, dado o distanciamento da instituição dos novos rumos da astrofísica e da rápida inovação dos instrumentos, além do pequeno volume de publicações. Era uma época em que ainda não existiam os mecanismos formais de apoio e avaliação da atividade científica. Esse trabalho procura identificar a real atividade do Observatório no conteúdo dos Relatórios Ministeriais que, ao final de cada ano, apresentava as atividades, sucessos e problemas enfrentados pela instituição. Questões como instrumental e recursos humanos necessários; entraves burocráticos e financeiros; e articulações com outros observatórios se complementaram entre si ao longo desses anos para definir o perfil institucional e alguns aspectos fundamentais para a construção da astronomia no país. É possível concluir que a ênfase em serviços geográficos e de meteorologia, ao lado da inadequação dos instrumentos e do local, quase fizeram desaparecer a pesquisa em astronomia. Porém, vale destacar a sobrevivência de alguns trabalhos, como, por exemplo, variação de latitude e observação de estrelas duplas que mantiveram importante intercâmbio com outros grupos de pesquisa, demonstrando o constante esforço dos astrônomos e das diretorias em defesa da atividade científica.

This paper describes the development process of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines) based on an integrated approach to pharmaceutical services, science, technology and innovation. It starts by contextualizing health and development in Brazil and features elements of the National Policy for Science, Technology and Innovation in Health in Brazil and the National Policy for Pharmaceutical Services. On presenting pharmaceutical policy guidelines, it stresses the lack of nationwide data. This survey, commissioned by the Brazilian Ministry of Health, has two components: household survey and evaluation of pharmaceutical services in primary care. The findings point to perspectives that represent, besides the enhancement of public policy for pharmaceutical services and public health, results of government action aimed at developing the economic and industrial health care complex to improve the health conditions of the Brazilian population. RESUMO O artigo apresenta o processo de construção da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamento a partir de uma concepção integradora da Assistência Farmacêutica, Ciência, Tecnologia e Inovação. Inicia-se contextualizando a saúde e o desenvolvimento no País e apresenta elementos da Política Nacional de Ciência Tecnologia e Inovação em Saúde no Brasil e da Política Nacional de Assistência Farmacêutica. Ao apresentar as diretrizes das Políticas Farmacêuticas, destaca-se a carência de dados de abrangência nacional. A presente pesquisa, encomendada pelo Ministério da Saúde, foi estruturada em dois componentes: inquérito domiciliar e avaliação dos serviços de assistência farmacêutica na atenção básica. As perspectivas dos resultados representam, além do incremento das políticas públicas farmacêuticas e de saúde pública, resultados de ações governamentais voltadas ao desenvolvimento do complexo econômico-industrial da saúde, visando a melhoria das condições de saúde da população brasileira.

Epidemiology is the study of occurrence, distribution and determinants of health-related events, including the application of that knowledge to the prevention and control of health problems. However, epidemiological studies, in most cases, have limited their research questions to determinants of health outcomes. Research related to the application of knowledge for prevention and control of diseases have been neglected. In this comment, we present a description of how population attributable fraction estimates can provide important elements for planning of prevention and control of diseases in Brazil. RESUMO Epidemiologia é o estudo da ocorrência, distribuição e determinantes de eventos relacionados à saúde da população, incluindo a aplicação desse conhecimento para a prevenção e o controle dos problemas de saúde. Entretanto, estudos epidemiológicos, na maioria das vezes, têm limitado suas perguntas de pesquisa aos fatores determinantes de desfechos em saúde. Pesquisas relacionadas à aplicação do conhecimento para ações de prevenção e controle de doenças têm sido negligenciadas. Nesse comentário, apresentamos uma descrição de como as estimativas de fração atribuível populacional podem fornecer importantes elementos para planejamento de ações de prevenção e controle de doenças no Brasil.

All regions of Brazil are potential areas for growing tropical fruits. As this country is already a great producer and exporter of tropical fruits, ionizing radiation has been the subject of studies in many commodities. An important project has been carried out to increase the commercial use of gamma radiation in our country. Instituto de Pesquisas Energeticas e Nucleares (IPEN)-CNEN/SP together with field producers in northeast region and partners like International Atomic Energy Agency (IAEA), CIC, Empresa Brasileira Pesquisa na Agricultura (EMBRAPA) joined to demonstrate this technology, its application and commercial feasibility. The objective of this study is to show advances in feasibility demonstrate the quality of the irradiated fruits in an international consignment from Brazil to Canada. In this work, Tommy Atkins mangoes harvested in northeast region of Brazil were sent to Canada. The fruits were treated in a gamma irradiation facility at doses 0.4 and 1.0 kGy. The control group was submitted to hydrothermal treatment (46 °C for 110 min). The fruits were stored at 11 °C for 10 days until the international transportation and kept at an environmental condition (22 °C) for 12 days, where their physical-chemical and sensorial properties were evaluated. The financial part of the feasibility study covers the scope of the investment, including the net working capital and production costs.

To analyze the relationships between victimization, perception of insecurity, and changes in routines. The 8,170 subjects of both sexes (49.9% women and 50.1% men) aged between 12 and 60 years, selected from a proportional stratified sampling, participated in this study. The measuring instrument was an adaptation of the National Survey on Victimization and Perception of Public Security. Chi-square tests were performed. The results show significant differences on victimization and sex regarding perception of insecurity, restrictions on everyday activities, and protection measures. 13.1% of those interviewed claimed to have been victims of a crime in the past 12 months. 52.7% of women considered their municipality as unsafe or very unsafe. In the case of men, this percentage was 58.2%. Female victims reported significant restrictions in everyday activities when compared to non-victims. In relation to men, the percentage of victims with a high restriction of activities was higher in male victims than non-victims. In the group of victimized women, the segment of women who opted for increased measures of protection against crime was larger than expected, while those of non-victims who took less protective measures was lower than expected. These same results were observed in the group of men. The experience of victimization implies a greater perception of insecurity. However, the climate of insecurity is widespread in a large number of citizens. Gender differences in a high-crime environment show the importance of investigating in depth the roles of both genders in the perception of insecurity and changes in routines. Analizar las relaciones existentes entre victimización, percepción de inseguridad y cambios en las rutinas. Participaron en este estudio 8,170 sujetos de ambos sexos (49.9% mujeres y 50.1% hombres) de entre 12 y 60 años, seleccionados a partir de un muestro estratificado proporcional. El instrumento de medida fue una adaptación de la Encuesta Nacional de Victimización y Seguridad Pública. Se realizaron pruebas Chi-cuadrado. Los resultados evidencian diferencias significativas en cuanto a victimización y sexo con respecto a percepción de inseguridad, restricciones de actividades cotidianas y medidas de protección. Un 13.1% de las personas entrevistadas afirmaron haber sido víctimas de un delito en los últimos doce meses. El 52.7% de las mujeres consideraron su municipio como inseguro o muy inseguro. En el caso de los hombres, este porcentaje fue de 58.2%. Las mujeres víctimas señalaron restricciones en la vida cotidiana significativas en comparación con las no víctimas. Con relación a los hombres, el porcentaje de víctimas con un alta restricción de actividades fue mayor en los hombres víctimas que en los hombres no víctimas. En el grupo de mujeres victimizadas, el segmento de mujeres que optaron por mayores medidas de protección frente a la delincuencia fue mayor de lo esperado, mientras que las mujeres no víctimas que asumieron menores medidas de protección fue menor de lo esperado. Estos mismos resultados se observaron en el grupo de los hombres. La experiencia de victimización lleva implícita una mayor percepción de inseguridad. Sin embargo, el clima de inseguridad se encuentra diseminado en gran cantidad de la ciudadanos. Las diferencias de género en un clima de alta criminalidad muestran la importancia de investigar a profundidad los roles de ambos sexos en la percepción de inseguridad y los cambios en las rutinas.

El rol de Ia colaboracion y el Modelo de Aprendizaje Basado en Proyectos (ABPr) mediante el lente de la Teoria de Actividad (CHAT): un estudio de caso con estudiantes de 9no grado

Delgado, Isabel C.

Los modelos de eensenanza y aprendizaje constructivistas conceptualizan el aprendizaje como un proceso activo. El modelo de Aprendizaje Basado en Proyectos (ABPr) se distingue por una serie de componentes, entre los cuales se destaca el aspecto colaborativo y cooperativo como un reto al momento de su implantacion. Son pocas las investigaciones que se concentran en este aspecto del modelo. En este estudio, se analizaron las diversas interacciones que surgen durante la implantacion de una unidad curricular sobre el tema de Geologia de Puerto Rico, la cual se diseno con el modelo ABPr cuyo enfoque es orientacion a proyectos. Particularmente, se examinaron las interacciones sociales que surgen entre los pares y entre pares y docente durante el proceso de planificacion y desarrollo de los productos finales, al igual que las interacciones entre los estudiantes y el material didactico en estas etapas del modelo. La investigacion es de tipo cualitativo e incorpora como diseno el estudio de caso. Las diversas interacciones constituyen la unidad de analisis. En el estudio participaron 19 estudiantes de 9no grado, a quienes se organizaron en 5 grupos colaborativos por temas de interes (Pangea, Placas tectonicas, Volcanes, Tsunamis y Terremotos). Las tecnicas que se utilizaron para recopilar los datos fueron: observaciones participativas, grupos focales y analisis de documentos (cuadernos reflexivos y respuestas de los estudiantes a la pregunta central del proyecto). Para el analisis de los datos se aplico la teoria de actividad (CHAT) que concentra la unidad de analisis en la actividad humana en un contexto particular. Los resultados del estudio senalan que las interacciones entre pares, entre pares y docente, asi como entre estudiantes y material didactico son fundamentales en el proceso de aprendizaje. Una mayor interaccion entre pares durante las etapas de planificar y desarrollar los productos finales de la unidad, promueve una mejor comprension de los conceptos de la unidad, segun evidencia los productos finales del ABPr. La interaccion con el docente es muy importante para mediar los conflictos y desacuerdos que surgen como parte de las interacciones entre pares. Por lo tanto, el uso de diversas estrategias de andamiaje por parte del docente durante las reuniones de los grupos colaborativos es esencial para el exito del modelo ABPr.

This article discusses elements of a theory of innovation from the perspective of innovation networks and social construction of technology, based on Habermas' Theory of Communicative Action and authors from the Sociology of Innovation. Based on the theoretical framework of the communicative production of scientific facts, we focus on innovation management as a basic dimension that must meet some organizational and methodological requirements in order to power its results. We present and discuss instruments such as Situational Planning, Prospective Analysis, Strategic Portfolio Management, and Networks Management that can help deal with the challenge of innovation and exploration of the future. We conclude that network organizational formats centered on reflexivity of interdisciplinary groups and planning approaches that encourage innovation criteria in assessing the attractiveness of activities and that help anticipate forms of innovation through systematic prospective analysis can potentiate the process of generating innovation as a product of networks. Resumo: No artigo são discutidos elementos de uma teoria da inovação numa perspectiva de redes de inovação e de construção social da tecnologia, a partir da Teoria do Agir Comunicativo de Habermas e de autores da Sociologia da Inovação. Com base no marco teórico da produção comunicativa de fatos científicos, focamos a gestão da inovação como uma dimensão fundamental que deve contemplar alguns requisitos, tanto de natureza organizacional quanto metodológica, para potencializar seus resultados. Apresentamos e discutimos instrumentos como o Planejamento Situacional, a Análise Prospectiva, a Gestão Estratégica de Portfólios e a Gestão de Redes que podem contribuir para o desafio da inovação e exploração do futuro. Conclui-se que formas organizativas em rede, centradas na reflexividade de grupos interdisciplinares, e enfoques de planejamento que estimulem o uso de critérios de inovação na avaliação da atratividade das atividades e que ajudem a antecipar formas de inovação por meio de uma análise prospectiva sistemática podem potencializar o processo de geração da inovação como produto de redes.

This review aims to develop a critical and current analysis of the basic structure of a Postgraduate program for proposing improvement actions and new evaluation criteria. To examine the items that are areas of concentration (AC), research lines (LP), research projects (PP), curricular structure and fundraising were consulted the Area Document, the 2013 Evaluation Report and the Assessment Sheets of Medicine III programs, evaluated in the 2010-2012 period. Consistency is recommended especially among AC, LP and PP, with genuine link between activities and permanent teachers skills and based on structured curriculum in the education of the student. The Program Proposal interfere, and much, in qualifying a program. The curriculum should provide subsidy to the formation of the researcher, through the core subjects, and development of PP, being the concept of disciplines to support lines and research projects. Fundraise should be set out in research projects and in the CV-Lattes. The area recommended that at least 40-50% of permanent teachers present fundraising and the minimum 20-25% of these teachers to have productivity scholarship PQ / CNPq during the triennium. It is necessary to promote wide discussion and find a consensus denominator for these issues. The actions should contribute to the improvement of evaluation forms and certainly for the qualification of the programs but graduate. Essa revisão tem como objetivo elaborar uma análise crítica e atual da estrutura básica de um programa de Pós-Graduação para a proposição de ações de aperfeiçoamento e novos critérios de avaliação. Para analisarem-se os itens áreas de concentração (AC), linhas de pesquisa (LP), projetos de pesquisa (PP), estrutura curricular e captação de recursos/fomentos foram consultados o documento de área, o relatório de avaliação 2013 e as fichas de avaliação dos programas da Medicina III, avaliados no triênio 2010-2012. A coerência é recomendada especialmente entre AC, LP e PP, com substancial vínculo entre atividades e competências do corpo de docentes permanentes e embasamento da grade curricular na formação do aluno. A Proposta do Programa interfere, e muito, na qualificação de um programa. A estrutura curricular deverá dar subsídio à formação do pesquisador, por meio das disciplinas nucleares, e ao desenvolvimento dos PP, de competência das disciplinas de apoio às linhas e aos projetos de pesquisa. Os fomentos devem ser indicados nos projetos de pesquisa e no CV-Lattes dos beneficiados/responsáveis pelos projetos. A área recomenda que, no mínimo, 40 a 50% dos docentes permanentes apresentem captação de recursos e que o mínimo de 20 a 25% desses docentes tenham bolsa de produtividade PQ/CNPq durante o triênio. Há que se promover ampla discussão e encontrar um denominador de consenso para essas questões. As ações deverão contribuir para o aprimoramento das fichas de avaliação e, certamente, para a qualificação dos programas de pós-graduação.

To analyze the Miniquestionário de Qualidade de Vida em Hipertensão Arterial (MINICHAL - Mini-questionnaire of Quality of Life in Hypertension) using the Item Response Theory. This is an analytical study conducted with 712 persons with hypertension treated in thirteen primary health care units of Fortaleza, State of Ceará, Brazil, in 2015. The steps of the analysis by the Item Response Theory were: evaluation of dimensionality, estimation of parameters of items, and construction of scale. The study of dimensionality was carried out on the polychoric correlation matrix and confirmatory factor analysis. To estimate the item parameters, we used the Gradual Response Model of Samejima. The analyses were conducted using the free software R with the aid of psych and mirt. The analysis has allowed the visualization of item parameters and their individual contributions in the measurement of the latent trait, generating more information and allowing the construction of a scale with an interpretative model that demonstrates the evolution of the worsening of the quality of life in five levels. Regarding the item parameters, the items related to the somatic state have had a good performance, as they have presented better power to discriminate individuals with worse quality of life. The items related to mental state have been those which contributed with less psychometric data in the MINICHAL. We conclude that the instrument is suitable for the identification of the worsening of the quality of life in hypertension. The analysis of the MINICHAL using the Item Response Theory has allowed us to identify new sides of this instrument that have not yet been addressed in previous studies. Analisar o Miniquestionário de Qualidade de Vida em Hipertensão Arterial (MINICHAL) por meio da Teoria da Resposta ao Item. Estudo analítico realizado com 712 pessoas com hipertensão arterial atendidas em 13 unidades de atenção primária em saúde de Fortaleza, CE, em 2015. As etapas da análise pela Teoria da Resposta ao Item foram: avaliação da dimensionalidade, estimação dos parâmetros dos itens e construção da escala. O estudo da dimensionalidade foi realizado sobre a matriz de correlação policórica e análise fatorial confirmatória. Para a estimação dos parâmetros dos itens, foi utilizado o Modelo de Resposta Gradual de Samejima. As análises foram conduzidas no software livre R com o auxílio dos pacotes psych e mirt. A análise permitiu a visualização dos parâmetros dos itens e suas contribuições individuais na mensuração do traço latente, gerando mais informação, permitindo a construção de uma escala com um modelo interpretativo que demonstra a evolução da piora da qualidade de vida em cinco níveis. Quanto aos parâmetros dos itens, houve bom desempenho daqueles referentes ao estado somático, pois apresentaram melhor poder de discriminar os indivíduos com pior qualidade de vida. Os itens relacionados ao estado mental foram os que contribuíram com menor quantidade de informação psicométrica no MINICHAL. Conclui-se que o instrumento é indicado para a identificação da deterioração da qualidade de vida em hipertensão arterial. A análise do MINICHAL pela Teoria da Resposta ao Item permitiu identificar novas facetas desse instrumento ainda não abordadas em estudos anteriores.

Sendo a Astronomia uma das cièncias mais antigas da humanidade, e considerando sua importáncia histórica e cultural, é de extrema releváncia que tópicos relacionados a ela sejam tratados nas escolas. Embora os Parámetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as Orientaçiacute;es Complementares aos Parámetros (PCN+) apontem a importáncia de uma abordagem significativa de conceitos relacionados à Astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano e sejam alvos da curiosidade natural dos jovens. Da observação dessa curiosidade em alunos de uma escola pública paulista, na cidade de Suzano, surgiu o interesse em investigar os conhecimentos básicos em Astronomia dos alunos do Ensino Médio desta escola, constituindo-se este como principal objetivo desta pesquisa. Para tanto foi elaborado um questionário de múltipla escolha aplicado inicialmente a 34 alunos do primeiro ano e, posteriormente, a mais 310, distribuídos entre as très séries do Ensino Médio dos períodos matutino e noturno. Dessa forma, observou-se que 73,9% dos estudantes identificaram o Sol como sendo uma estrela, 67,1% mostraram compreender a sucessão entre dia e noite e 52,3% relacionaram o Big Bang à origem do Universo. Em contrapartida, apenas 34,5% relacionaram as estaçíes do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influència gravitacional simultánea da Lua e do Sol como responsável pelo fenòmeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distáncia e 34,2% reconheceram as estrelas cadentes como meteoros, evidenciando-se assim o pequeno discernimento dos estudantes quanto aos fenòmenos e termos astronòmicos do cotidiano. Além disso, foram comparadas as respostas de alun! os de diferentes séries e períodos, observando-se, dentre ou tras coi sas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tópicos relacionados à astronomia no Ensino Médio não tem contribuído de forma significativa para uma maior compreensão dos fenòmenos e conceitos.

Prediction uncertainty of plume characteristics derived from a small number of measuring points

NASA Astrophysics Data System (ADS)

French, H. K.; van der Zee, S. E. A. T. M.; Leijnse, A.

A small number of measuring points may inflict a bias on the characterisation of flow and transport based on field experiments in the unsaturated zone. Simulation of pure advective transport of a Gaussian plume through a setup of 30 regularly placed measuring points revealed regular temporal fluctuations about the real spatial moments. An irregular setup predicted both irregular fluctuations and larger discrepancies from the real value. From these considerations, a regular setup is recommended. Spatial moments were sensitive to the plume size relative to the distance between individual measuring points. To reduce prediction errors of the variance, the distance between the measuring points should be less than twice the standard deviation of the examined plume. The total size of the setup should cover several standard deviations of the plume to avoid mass being lost from the monitored area. Numerical simulations of a dispersing plume (comparing calculations based on 9000 nodes with 30 measuring points) revealed that vertical and horizontal centres of mass were predicted well at all degrees of heterogeneity, and the same was the case for horizontal variances. Vertical variances were more susceptible to prediction errors, but estimates were of the same order of magnitude as the real values. Résumé Lorsque l'on cherche à caractériser l'écoulement et le transport à partir d'expériences de terrain dans la zone saturée, il arrive qu'un petit nombre de points introduisent un biais. La simulation d'un transport purement advectif d'un panache gaussien au travers d'un ensemble de 30 points de mesures espacés régulièrement fait apparaître des variations temporelles régulières autour des moments spatiaux réels. Un ensemble irrégulier conduit à prédire à la fois des variations irrégulières et de plus grandes divergences par rapport à la valeur réelle. A partir de ces constations, un ensemble régulier est recommandé. Les moments spatiaux sont apparus sensibles à la dimension du panache en fonction de la distance entre les différents points de mesure. Afin de réduire les erreurs de prédiction de la variance, la distance entre les points de mesure doit être inférieure au double de l'écart-type du panache examiné. La dimension totale de l'ensemble doit couvrir une étendue de plusieurs écarts-types du panache pour éviter qu'une partie de la matière échappe à la zone surveillée. Des simulations numériques du panache en dispersion (les calculs de comparaison sont basés sur 9000 nœuds avec 30 points de mesure) montrent que le centre vertical et le centre horizontal de la matière dispersée ont été bien prédits à tous les degrés d'hétérogénéité, de même que pour les variances horizontales. Les variances verticales ont été plus sensibles aux erreurs de prédiction, mais les estimations étaient du même ordre de grandeur que les valeurs réelles. Resumen Un número pequeño de puntos de medida puede producir un sesgo en la caracterización en campo del flujo y transporte de solutos en la zona no saturada. La simulación de transporte advectivo (no difusivo) de un penacho Gaussiano a travs de un conjunto de 30 puntos de medida regularmente distribuidos revelan fluctuaciones temporales regulares de los momentos espaciales del penacho. Una distribución irregular de puntos de medida predijo a su vez fluctuaciones irregulares, más alejadas de la realidad, por lo que se recomienda el uso de esquemas de muestreo regulares. Los momentos espaciales fueron sensibles a la relación entre tamaño del penacho y distancia entre puntos de medida. Para reducir los errores en la predicción de la varianza, la distancia entre puntos de observación debe ser menor que dos veces la desviación estándar del penacho. El tamaño del área muestreada debe cubrir varias desviaciones estándar del penacho para evitar perder parte de la masa. Las simulaciones numricas en un penacho dispersivo, comparando los cálculos basados en 9000 nudos con las 30 medidas, mostraron que las posiciones de los centros de masa y las varianzas en dirección horizontal se predijeron bien independientemente del grado de heterogeneidad. Las varianzas verticales, sin embargo, fueron más susceptibles a errores de predicción, pero las estimaciones eran del mismo orden de magnitud que los valores reales.

Introducción: una ley exponencial se ha hallado para los sistemas dinámicos caóticos cardiacos, logrando cuantificar las diferencias entre dinámicas cardiacas normales y  patológicas.Metodología: Se analizaron 120 registros electrocardiográficos, 40 correspondían a sujetos dentro de los límites de normalidad y 80 con diferentes patologías. Para cada holter se analizaron los atractores generados con los datos durante 18 horas y durante toda la dinámica. Se calculó la dimensión fractal del atractor y su ocupación espacial. A estas medidas se aplicó la evaluación matemática diagnostica desarrollada previamente, comparando la evaluación para 18 horas y para todo el registro; finalmente se calculó la sensibilidad, especificidad y coeficiente Kappa.Resultados: Para las dinámicas normales los espacios de ocupación en la rejilla Kp estuvieron entre 200 y 381 en la evaluación de la totalidad del holter, y entre 201 y 384 en la evaluación durante 18 horas, mostrando la cercanía en las medidas, lo que permite que la disminución en el tiempo de la evaluación sea consistente, esta misma cercanía se observó para las dinámicas enfermas y agudas.Conclusión: Se evidenció la aplicabilidad clínica en 18 horas de la ley exponencial en la dinámica cardiaca caótica asociada a arritmias mostrando ser de utilidad para la predicción de la evolución hacia estados agudos de la dinámica.

Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

El ancho equivalente WHβ de la linea de Hβ en emisión y la razón [0 III]/Hβ del par λλ4959, 50 7 A del [0111], fueron medidos en 23 regiones HII de la Peque˜a Nube de Magallanes, por medio de la fotometría fotoeléctrica a través de un sistema de tres filtros interferenciales: dos Hβ , con bandas pasantes de 100 y 30 A, y un [0111] centrado en 5000 A y con banda pasante de 50 A. Las observaciones fueron realizadas con los telescopios de 1.60-m y 0.60-m del Laboratorio Nacional de Astrofísica, Brasópolis, Brasil. Fueron escogidos diafragmas suficientemente grandes para captar la radiación integrada de cada región HII. Las medidas fueron calibradas por comparación a un conjunto de nebulosas planetarias con flujos absolutos bien definidos. A través de la comparación entre los datos observacionales y modelos evolutivos de WHβ y [0 III] /Hβ (Copetti et al.1986', Astr. and Ap., 156, 111), las edades de las regiones HIl fueron estimadas. Basada en la distribución espacial de las edades de regiones HIl, la historia de la formación estelar reciente en la Pequeña Nube de Magallanes es analizada. La similitud de las medidas de WH&beta y [OIII]/WHβ entre las regiones H II observadas sugiere que hubo una explosión de formación estelar a 4±1 x106 años en la Pequeña Nube de Magallanes.

Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students.

Nos centramos en el estudio de las variaciones en la temperatura, las precipitaciones, la duración del día, las variaciones en el tamaño de las sombras y los cambios en los aspectos de la Luna. Nuestro foco de análisis se centró en discutir el conocimiento que estos estudiantes tenían sobre los temas indicados al inicio y término de la propuesta. Los resultados mostraron una percepción limitada que los estudiantes tienen de su alrededor la cual, sin embargo, se expandió debido a las actividades llevadas a cabo, sobre todo en relación con la Luna. Trabajar con medidas sistemáticas revela el manejo cuidadoso de los datos para que sean comprensibles para los estudiantes, así como el trabajo con las sombras para que comprendan primero como se forman estas para después trabajarlas en Astronomía.

To define the antecedents, consequents, and attributes of spiritual coping. Rodgers' evolutionary model for concept analysis was used to guide an integrative literature review of qualitative research. Six qualitative articles were included and elements that define and contextualize the concept were identified. Three new nursing diagnoses are proposed, based on qualitative findings. These new diagnoses should be submitted to clinical validation in different cultural and religious backgrounds, but the inclusion in the taxonomy highlights a holistic perspective concerning the spiritual dimension of patients' responses in life and health transitions, and so, bringing the approach to spirituality into nursing practice.

Several scientists of the Brazilian Institute for Space Research (Instituto de Pesquisas Espacias, or INPE; headquarters at Sāo Jose dos Campos, Sao Paulo) went to Manaus (3°S, 60°W), in the central region of the Amazon forest during July-August 1985 to study the atmosphere of the equatorial rainforest. The expedition to the Amazon was part of a large binational atmospheric chemistry field campaign that was organized to measure several atmospheric gases of the forest environment. This was definitely the largest scientific field expedition in this field ever performed on Brazilian territory.

O principal objetivo do projeto Observatórios Virtuais é o ensino na área de ciências através de atividades práticas desenvolvidas em colaboração entre instituições de pesquisa em astronomia e escolas de ensino médio e fundamental. Este ano deverá ser concluída a implantação do programa piloto de estudos, pesquisas e observação astronômica direta, com utilização em tempo real de telescópios robóticos, que assim funcionarão como "observatórios virtuais". O objetivo pedagógico das atividades práticas baseadas nas imagens atronômicas é desenvolver as habilidades e competências dos alunos no uso do método científico. Para isso, serão realizados projetos interdisciplinares, a partir de observações astronômicas, já que a astronomia é uma área interdisciplinar por excelência. Essas atividades terão níveis diferenciados de complexidade, que podem ser adequados aos vários graus do ensino e realidades regionais. Será dada ênfase ao desenvolvimento e aplicação em São Paulo, onde atua a equipe do IAG/USP. Como resultados apresentados no presente trabalho, temos a criação de um software em português para o processamento de imagens obtidas através de CCDs e a elaboração de material para as atividades educacionais relacionadas.

EFFECTIVE INDICATORS FOR SCIENCE INTERNATIONALIZATION.

PubMed

Cunha-Melo, José Renan da

2015-01-01

To review of concepts and actions that aim to analyze the effects of internationalization of science and education, with emphasis in the medical field and its basement in development policies adopted by nations, exploring the potential for international interdisciplinary cooperation of each laboratory, department, university or institute. Search of indicators to assess the degree of internationalization of universities and research institutes in several interconnected levels: organizational, regional, sectoral and global, and policy-making in science, technology innovation and higher education. Scientific research is still carried out individually, but is now much more closely integrated with other social processes. The scientist is no longer a stranger who is allowed to surrender to his hobby to do what it wants. Internationalization of research and medical education, although it is among the topics of greatest need, as the globalized world, is difficult activity to be assessed. The leaders seem to have understood that the knowledge societies, leading to economic policy based on knowledge, can result in economic and social progress of nations. This fact has motivated increasingly the incentive to actions aimed at addressing global problems (eg health, climate change) by funding research that generates new knowledge. The consensus is that the internationalization of science is desirable and necessary for the sustainable development of nations. However it cannot be done only by encouraging and promoting the outward students and researchers abroad. It is necessary, in addition, offer conditions to foreign researchers and students teachers to work in collaboration with Brazilian and raise the country to international scientific standards. Apresentar revisão dos conceitos e ações que objetivam analisar os efeitos da internacionalização da ciência e da educação, com ênfase na área médica e seu embasamento nas políticas de desenvolvimento adotadas pelas nações, explorando o potencial para cooperação internacional interdisciplinar de cada laboratório, departamento, universidade ou instituto. Procura de indicadores que possam avaliar o grau de internacionalização das universidades e institutos de pesquisa em vários níveis interconectados: organizacional, regional, setorial e global e para definição de políticas nas áreas de ciência, tecnologia inovação e educação superior. A pesquisa científica ainda é realizada individualmente, mas está atualmente muito mais intimamente integrada a outros processos sociais. O cientista não é mais um estranho que tem permissão para entregar-se ao seu passatempo de fazer aquilo que bem entende. Internacionalização da pesquisa e da educação médica, embora esteja entre os tópicos de maior reconhecimento como sendo necessidade do mundo globalizado, é atividade difícil de ser avaliada. Os governantes parecem ter entendido que as sociedades do conhecimento, induzindo a política econômica baseada no conhecimento pode resultar em progresso econômico e social das nações. Esse fato tem motivado de forma crescente o incentivo às ações que visam a abordagem de problemas globais (e.g. saúde, mudanças climáticas) pelo financiamento da pesquisa que gera conhecimento novo. É consenso que a internacionalização da ciência é desejável e necessária para o desenvolvimento sustentável das nações. Entretanto ela não pode ser feita somente incentivando e fomentando a ida de estudantes e pesquisadores para o exterior. É preciso, em adição, oferecer condições a professores pesquisadores e estudantes estrangeiros para que possam atuar em colaboração com os brasileiros e elevar o país aos padrões científicos internacionais.

This work presents the elaboration of an answer to the question "Is the dark side of the moon ever illuminated by the sun?", in which issues related to the students' conceptions, how they arise, and the core elements that constitute a "good answer" are considered. These issues are initially elaborated from a literature review of the research in the field; then, and also based on this review, a didactic model that involves the relative motions of the Earth - Moon - Sun system is proposed. A description of the application of this model in a learning environment within middle school students is described. This work confirms the students' initial concepts described in the literature; on the other hand, the questions asked by students during the activity provide evidence that meaningful learning, at least to some degree, has occurred. Este trabalho apresenta a elaboração de uma resposta à pergunta "O lado escuro da Lua nunca apanha sol?" na qual são consideradas questões relacionadas às concepções iniciais dos alunos, de onde elas surgem e os elementos centrais que constituem uma "boa resposta". Essas questões são tratadas, inicialmente, a partir de uma revisão da literatura sobre pesquisas na área e, em seguida, também com base nessa revisão, um objeto modelo didático que envolve os movimentos relativos do sistema Terra - Lua - Sol é proposto. Uma descrição detalhada da aplicação deste modelo em um ambiente de aprendizagem com alunos do ensino fundamental é relatada. As concepções iniciais apresentadas na literatura se confirmam e os questionamentos feitos pelos estudantes por ocasião da aplicação do modelo fornecem indícios de que uma aprendizagem significativa, pelo menos em algum grau, ocorreu. El artículo se presenta el desarrollo de una respuesta a la pregunta "¿El lado oscuro de la luna nunca toma sol?", en la que se consideran algunas cuestiones vinculadas que se refieren a las concepciones iniciales de los estudiantes, dónde surgen y los elementos básicos que componen una "respuesta correcta". Estas cuestiones se tratan inicialmente a partir de una revisión bibliográfica de la investigación en el área; seguidamente, y también sobre la base de ésta revisión, se propone un modelo didáctico que ejemplifica los movimientos relativos del sistema Tierra - Luna - Sol. Se describe a continuación una aplicación de este modelo en un entorno de aprendizaje con alumnos del ciclo primario. Los conceptos iniciales presentados en la literatura se confirman y las cuestiones planteadas por los estudiantes durante la implementación del modelo proporcionan evidencia de que se ha producido un aprendizaje significativo, al menos en cierta medida.

Radiofontes extragalácticas são um dos principais contaminantes nas medidas da Radiação Cósmica de Fundo (RCF) em freqüências abaixo de 200 GHz. O estudo de seu comportamento espectral permite determinar a contribuição destas fontes às anisotropias intrísincas da RCF. Um dos experimentos recentes concebidos para estudar a RCF é o BEAST (Background Emission Anisotropy Scanning Telescope), cujos primeiros resultados foram publicados em fevereiro de 2003. Nos últimos meses, geramos mapas do céu nas freqüências de 30 GHz e 41 GHz, para um total de 648 horas de observação entre julho e outubro de 2002. Identificamos 4 fontes puntiformes extragalácticas na região do céu situada entre 0h < RA < 24 h e +32° < DEC < +42°, com relação S/R > 4,3 e situadas a pelo menos 25° acima do Plano Galáctico. Suas contrapartidas em 5 GHz, segundo o catálogo GB6, são: J1613+3412, J1635+3808, J0927+3902 e J1642+3948. Estas fontes também foram identificadas pelo satélite WMAP sendo que três coincidem com as observadas pelo BEAST dentro da incerteza do feixe do telescópio e a quarta encontra-se bastante próxima (J1613+3412), embora não seja coincidente. As estimativas preliminares de fluxos obtidas para esses objetos são, respectivamente, 0,51; 0,97; 1,08 e 1,6 Jy em 41 GHz. Usando estes resultados e medidas de fluxos em outras frequências existentes na literatura, apresentamos uma estimativa dos índices espectrais destes objetos no intervalo de frequências entre 4,85 GHz e 41 GHz.

El estudio experimental de las interacciones de átomos Rydberg altamente excitados con campos eléctricos ha experimentado un creciente interés durante las dos últimas décadas debido, en gran medida, al desarrollo de nuevas técnicas para crear y estudiar átomos Rydberg en el laboratorio. Acompañando a estas nuevas técnicas experimentales, es necesario el desarrollo de modelos teóricos que nos permitan contrastar sus medidas y conocer mejor los fundamentos de los mismos. Desde el punto de vista teórico el conocimiento del desdoblamiento de los niveles energéticos de un átomo en función de la magnitud del campo eléctrico aplicado (lo que se conoce como mapa Stark) es el mejor punto de partida para la descripción del sistema y un prerrequisito fundamental para el cálculo de distintas propiedades atómicas en presencia del campo eléctrico tales como intensidades de transición, umbrales de ionización de campo eléctrico, tiempos de vida, posición y anchura de cruces evitados, etc. En este trabajo presentamos la adaptación del método de orbitales de defecto cuántico [1,2,3] al tratamiento del efecto Stark (SQDO) [4] y su aplicación al cálculo de los desdoblamientos energéticos y fuerzas de oscilador de estados Rydberg en los átomos de Li, Na y K. El propósito de este estudio es, por un lado, desarrollar métodos fiables para la determinación de propiedades atómicas en presencia de campos eléctricos y, por otro, mostrar la fiabilidad de las funciones de onda QDO en la descripción del efecto Stark en sistemas atómicos.

Estudos recentes da cinemática da região dentro de 1 kpc do núcleo de galaxias Seyfert próximas usando espectroscopia de fenda longa com alta resolução espacial (~ 100 pc ou melhores) encontraram uma queda na dispersão de velocidades nas regiões centrais dentro de um raio de ~ 300 pc do núcleo. Essa queda vem sendo tentativamente explicada por um cenário evolutivo em que um evento de formação estelar recente cria as estrelas da região central em um disco de dimensões 300 pc. Desde sua criação, tais estrelas não tiveram tempo de "virializar", ou seja, seguir a distribuição radial de dispersões de velocidades determinada pelo campo gavitacional da galáxia e, portanto, a dispersão de velocidades medida nessa região do bojo acaba sendo menor do que a dispersão medida nas vizinhanças. No presente trabalho investigamos a cinemática estelar no núcleo das galáxias Seyfert NGC 4051 e NGC 4941 usando o tripleto do Ca ii (8500 Å) em absorção. Os dados foram obtidos com o IFU GMOS no telescópio Gemini. O elemento de resolução espacial nas galáxias é da ordem de 30 pc. No intervalo espectral coberto pelo espectrografo a linha [S iii] (9068 Å) também é visível, o que permite estudar a cinemática do gás na mesma região. Serão apresentados mapas bi-dimensionais da velocidade e dispersão de velocidades das estrelas e do gás, além de imagens na linha [S iii] que mapeia o gás de alta excitação.

Resumo Contexto Os benefícios para a saúde decorrentes da prática regular de atividade física estão bem documentados. Entretanto, são raros os estudos associando essa prática ao comportamento sedentário e ao risco cardiovascular em adolescentes. Objetivos Pretende-se avaliar a prática de atividade física, o comportamento sedentário e a associação com o risco cardiovascular mensurado pelo escore Pathobiological Determinants of Atherosclerosis in Youth (PDAY). Métodos Estudo transversal desenvolvido nas escolas públicas estaduais de Campina Grande, PB, Brasil, com 576 adolescentes de 15 a 19 anos, incluindo variáveis socioeconômicas, demográficas, de estilo de vida e clínicas. Os dados foram coletados através de formulário validado, antropometria, aferição da pressão arterial e exames laboratoriais. Foram utilizadas medidas descritivas, teste do qui-quadrado de Pearson e regressão logística binomial. Trabalhou-se com o SPSS 22.0 se adotou intervalo de confiança de 95%. Resultados A idade média foi de 16,8 anos. A maioria dos adolescentes era do sexo feminino (66,8%), não branco (78.7%) e pertencente às classes C, D e (69,1%). Quanto ao sedentarismo e à insuficiência de atividade física, as prevalências foram de 78,1% e 60,2%, respectivamente. De acordo com o escore PDAY, 10,4% dos adolescentes apresentaram alto risco cardiovascular; 31,8% risco intermediário; e 57,8%, risco baixo. Verificou-se que PDAY esteve associado ao sexo e à adiposidade abdominal. Conclusões Ficou comprovado que adiposidade abdominal e sexo masculino representam importantes fatores de risco cardiovascular em adolescentes. Considerando-se a presença de um fator de risco modificável, medidas preventivas voltadas ao estilo de vida são essenciais. PMID:29930648

Analyze the definitions and dimensions of empowerment. Identify the strengths and weaknesses of empowerment measures based on the conceptual model. This was a comprehensive literature review of publications on the MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Twenty-nine articles were selected. Seventeen definitions and seven dimensions of empowerment, and 10 empowerment measures were selected. Empowerment can be seen as an enabling process involving a shift in the balance of power, or as an outcome of this process. The dimensions reflect outcome indicators, such as participation in decision-making and control, and process indicators, such as knowledge acquisition and coping skills. Six of the tools analyzed by this study could be said to provide a robust measure of patient empowerment. we propose a definition of empowerment that helps to deepen understanding of the term and, therefore, its operationalization.

Se identificaron 17 definiciones, 7 propuestas de dimensiones y 10 instrumentos de medida. Empoderamiento puede ser un proceso de capacitación o habilitación en el que se transfiere el poder de un individuo a otro, o bien un resultado producto de ese proceso. Las dimensiones reflejan indicadores de resultados como son la participación en la toma de decisiones y tomar el control, e indicadores relativos al proceso como son la adquisición de conocimientos y las habilidades de afrontamiento. De los instrumentos analizados seis son los instrumentos que presentan mayor robustez. Se propone una definición de empoderamiento que puede ayudar a mejorar la comprensión del término y por lo tanto a operacionalizarlo.

To evaluate the interday reproducibility, agreement and validity of the construct of short version of the Depression Anxiety Stress Scale-21 applied to adolescents. The sample consisted of adolescents of both sexes, aged between 10 and 19 years, who were recruited from schools and sports centers. The validity of the construct was performed by exploratory factor analysis, and reliability was calculated for each construct using the intraclass correlation coefficient, standard error of measurement and the minimum detectable change. The factor analysis combining the items corresponding to anxiety and stress in a single factor, and depression in a second factor, showed a better match of all 21 items, with higher factor loadings in their respective constructs. The reproducibility values for depression were intraclass correlation coefficient with 0.86, standard error of measurement with 0.80, and minimum detectable change with 2.22; and, for anxiety/stress: intraclass correlation coefficient with 0.82, standard error of measurement with 1.80, and minimum detectable change with 4.99. The short version of the Depression Anxiety Stress Scale-21 showed excellent values of reliability, and strong internal consistency. The two-factor model with condensation of the constructs anxiety and stress in a single factor was the most acceptable for the adolescent population.

A amostra foi composta por adolescentes de ambos os sexos, com idades entre 10 e 19 anos, recrutados de escolas e centros esportivos. A validade de construto foi realizada por análise fatorial exploratória, e a confiabilidade foi calculada para cada construto, por meio de coeficiente de correlação intraclasse, erro padrão de medida e mudança mínima detectável. A análise fatorial combinando os itens correspondentes a ansiedade e estresse em um único fator, e depressão em um segundo fator apresentou melhor adequação de todos os 21 itens, com cargas fatoriais mais altas em seus respectivos construtos. Os valores de reprodutibilidade para a depressão foram coeficiente de correlação intraclasse com 0,86, erros padrão de medida com 0,80 e mudança mínima detectável com 2,22 e, para a ansiedade/estresse, foram coeficiente de correlação intraclasse com 0,82, erro padrão de medida com 1,80 e mudança mínima detectável com 4,99. A versão reduzida da Depression Anxiety Stress Scale-21 apresentou excelentes valores de confiabilidade e também uma forte consistência interna. O modelo de dois fatores com a condensação dos construtos ansiedade e estresse em um único fator foi o mais aceitável para a população adolescente.

To conduct a data survey on the subject of medical claims involving civil liability in ophthalmology at the São Paulo Court of Appeals. A case law research was carried out on the São Paulo Court of Appeals website searching for the keyword "ophthalmologist" for all years until 2016. Of the 65 cases found, 29 were selected. There has been an increase in the number of claims in ophthalmology, especially in surgical procedures on the anterior chamber of the eye. Most lower court judgments were for defendant. The study suggested the need for specialists to exercise the required amount of care when treating the patients, so that they may understand the risks inherent to the procedure. Despite the increase in claims, most decisions were favorable for the physician. Realizar um levantamento de dados sobre a temática dos processos envolvendo responsabilidade civil em sede da Oftalmologia no Tribunal de Justiça do Estado de São Paulo. Foi realizada uma pesquisa jurisprudencial por palavra-chave no site do Tribunal de Justiça do Estado de São Paulo com o seguinte termo de pesquisa "oftalmologista" para todos os anos até 2016. Foram encontrados 65 processos, dos quais 29 foram selecionados. Observou-se tendência ao aumento de processos na área, e predominância de processos em procedimentos oftalmológicos cirúrgicos em câmara anterior do olho. A maioria das sentenças de primeira instância foi improcedente. O estudo aponta para a necessidade de atenção dos especialistas para com o paciente, no sentido de que ele compreenda os riscos inerentes ao procedimento. Apesar do aumento de processos, a maioria permanece favorável ao médico.

Przedmiotem artykułu jest przegląd prac badawczych dotyczących związku między cechami środowiska sąsiedzkiego a używaniem przez młodzież substancji psychoaktywnych. W pierwszej części pracy opisano sposoby definiowania obszaru środowiska sąsiedzkiego, w drugiej scharakteryzowano podstawy teoretyczne badań, w trzeciej - metody pomiaru cech środowiska sąsiedzkiego, a w czwartej przedstawiono wynik badań. Najczęściej przywoływanymi w badaniach teoriami, wyjaśniającymi związek między środowiskiem sąsiedzkim a zachowaniem młodzieży były teoria społecznej dezorganizacji oraz teoria kapitału społecznego. Odwoływano się ponadto do mechanizmów wpływu środowiska sąsiedzkiego na młodzież, takich jak: mechanizm norm i kolektywnej skuteczności, mechanizm zasobów instytucjonalnych, mechanizm relacji rodzinnych, mechanizm poczucia wspólnoty ze społeczności lokalną oraz model kolektywnego stylu życia. Najpowszechniej wykorzystywanym źródłem informacji o cechach środowiska były dane ze spisu powszechnego dotyczące społecznej i demograficznej charakterystyki mieszkańców. Stosowano również takie metody pomiaru, jak obserwacje w terenie, analiza dokumentacji oraz ankiety i wywiady z osobami badanymi, młodzieżą i rodzicami młodych ludzi. Wyniki badań potwierdziły, że cechy środowiska sąsiedzkiego mają bezpośredni i pośredni wpływ na sięganie przez młodzież po papierosy, alkohol i narkotyki. Stwierdzono, że znaczącym czynnikiem ryzyka jest charakterystyczna dla niekorzystnych środowisk łatwa dostępność substancji psychoaktywnych. Czynnikami chroniącymi są bezpieczeństwo w sąsiedztwie, kontrola społeczna oraz dostępność zasobów instytucjonalnych. Zaproponowane przez badaczy modele teoretyczne, odnoszące się do wpływu środowiska sąsiedzkiego na zachowanie młodzieży, wyznaczają obiecujące obszary badań. Zebrane dotychczas wyniki wskazują, że w działaniach profilaktycznych i interwencyjnych istotne znaczenie ma kształtowanie indywidualnych czynników chroniących młodzież przed negatywnym wpływem środowiska sąsiedzkiego, poprawa dostępności do zasobów materialnych oraz wzmacnianie kapitału społecznego młodych ludzi.

Comparing foot length measurements of newborns in high and low risk pregnancies at a public hospital in Goiânia, GO, Brazil. A cross-sectional study carried out between April, 2013 and May, 2015, with a sample consisting of 180 newborns; 106 infants of women from high-risk pregnancies and 74 of women from low-risk pregnancies. Data were descriptively analyzed. Foot length measurement was performed using a stiff transparent plastic ruler, graduated in millimeters. The length of both feet was measured from the tip of the hallux (big toe) to the end of the heel. A statistically significant relationship was found between the foot length and newborn's weight, between the cephalic and thoracic perimeters in the high-risk group and between the cephalic perimeter in the control group. There is a need for creating cut-off points to identify newborns with intrauterine growth disorders using foot length.

The professor plays a fundamental role in a graduate program, considering he/she is who plans and performs a great part of the tasks, and he/she is also responsible for spreading knowledge among students. The professor should use didactical resources for his/her continuous qualification, being responsible for situations favoring the development of students who should learn according to the best and easier way. The homogeneity in the postgraduate program consists of having subgroups of research corresponding to the Areas of Concentration, where each subgroup works with some distinct topics of research. It is desirable that the staff of postgraduate program has a significant and high quality scientific production, homogeneously distributed among them. The professors must systematically search for resources for research in agencies supporting research, not only for sponsoring the studies, but also for adding value to the researchers involved in the whole activities. The postgraduate programs need to support the professional qualification of their staff who should improve their knowledge on epidemiology for clinical studies, ethics in research and teaching skills. Two characteristics of the postgraduate system in Brazil are the nucleation and solidarity, based on the capacity and/or interest of those more structured programs to help those beginners, cooperating with their activities. The Capes (the national governmental agency responsible for coordinating and evaluating all postgraduate programs in Brazil) valorizes the social insertion in the context of postgraduate programs´ activities. It includes the recognition of activities with technological, cultural, educational and social impact as criteria for evaluation of the programs. Does exist an ideal model of postgraduate program? We think that there is no a mathematical formulae nor an ideal model for a postgraduate program. Each institution should make adaptations and search for improvements of their faculty and students´ teams. O docente tem importância fundamental no programa de pós-graduação, pois é quem planeja e executa grande parte das tarefas, sendo também o responsável por difundir conhecimentos aos alunos. O professor deve utilizar recursos didáticos que o qualifiquem continuamente, criando condições favoráveis para que o aluno se desenvolva e aprenda da melhor maneira e com mais facilidade. A homogeneidade no grupo de pós-graduação consiste da presença de subgrupos de pesquisa correspondentes às Áreas de Concentração, onde cada subgrupo trabalhe com algumas linhas de pesquisas diversificadas. É desejável que o corpo docente tenha significativa produção científica, de qualidade e distribuída homogeneamente entre os docentes. Estes devem sistematicamente buscar recursos em agências de fomento para pesquisa, tanto para o custeio dos estudos, quanto para a valorização dos pesquisadores envolvidos em todas as atividades. Os programas de pós-graduação precisam investir na formação de seus docentes, os quais devem aprimorar seus conhecimentos em epidemiologia de estudos clínicos, ética em pesquisa e em didática. Duas das características do sistema de pós-graduação no Brasil são a nucleação e a solidariedade, embasadas na capacidade e/ou interesse dos mais estruturados se solidarizarem com os programas iniciantes, cooperando com as suas atividades. A Capes valoriza a inserção social no contexto das atividades dos programas de pós-graduação, prevendo nos critérios de avaliação o reconhecimento de atividades com impacto tecnológico, cultural, educacional e social. Existe um modelo ideal de pós-graduação? Partimos do pressuposto de que não há uma fórmula matemática ou modelo ideal de pós-graduação e sim que cada instituição deve se adequar e buscar aperfeiçoar seu corpo docente e discente.

At the Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, Brazil, there is a facility (thorium purification plant) where materials with high thorium concentrations are manipulated. In order to estimate afterwards the lung cancer risk for the workers, the thoron daughter (212Pb) levels were assessed and the committed effective and lung committed equivalent doses for workers in place. A total of 28 air filter samples were measured by total alpha counting through the modified Kusnetz method, to determine the 212Pb concentraion. The committed effective dose and lung committed equivalent dose due to 212Pb inhalation were derived from compartmental analysis following the ICRP 66 lung compartmental model, and ICRP 67 lead metabolic model.

The inclusion of basic education teachers in the survey domain is a controversial issue and fully debated in the academy. The opportunity for a collective work that incorporated school teachers from a public school to a university's group of physics teaching at university allowed us to glimpse the redefinition of the function of a science teacher (a coauthor of this paper) by himself, such that now he includes research on the knowledge construction by students in his teacher practice. The formation of inter-institutional groups for action planning and research in these areas has proved productive for the task of knowledge construction to support educational processes in school, while the university enriches its collection of experiences critically validated, and can consider the results in teachers initial and continued education. The active participation of the teacher in a research group at the university led him to reflect on the possible didactical ways to be described, analyzed and communicated to other teachers. The construction of a pedagogy that took into account the mental models of students on the basic topics of astronomy, and the changes developed resulting from the lessons taught, led to far-reaching consequences on the pedagogy adopted by the teacher, who incorporates now a new vision of science and alternative forms to dialogue with students, essential components for a researcher in Science Education. La inclusión de los maestros de la escuela básica en el universo de la investigación es polémica y está en amplio debate en el mundo académico. La oportunidad de trabajo colectivo de los maestros de una escuela pública en Río de Janeiro con un grupo universitario de enseñanza de la física nos ha permitido vislumbrar la redefinición de la función de un maestro de ciencias (uno de los coautores de este documento) por él mismo, ahora para incluir la investigación sobre la construcción del conocimiento por los alumnos en su práctica como docente. La formación de grupos interinstitucionales para la planificación de la acción y la investigación ha resultado productiva para el trabajo de construcción de conocimiento de apoyo a los procesos educativos en la escuela, mientras que la universidad enriquece su colección de experiencias validadas, considerando los resultados de la educación inicial y continua de maestros. La participación activa del maestro en un grupo de investigación en la universidad lo llevó a reflexiones sobre los posibles caminos didácticos que pueden ser descriptos, analizados y comunicados a los demás docentes. La construcción de una pedagogía propia, que tuvo en cuenta los modelos mentales de los estudiantes sobre los temas básicos de astronomía, y los cambios desarrollados a partir de las lecciones que enseñó, trajeron consecuencias de largo alcance sobre la pedagogía adoptada por el maestro, que ahora incorpora una nueva visión de la ciencia y formas alternativas al diálogo con los estudiantes, los componentes esenciales para un investigador en Educaciónen Ciencias. A inclusão do professor da escola básica no universo da pesquisa é questão controvertida e em pleno debate no meio acadêmico. A oportunidade de trabalho coletivo que incorporou professores de uma escola municipal no Rio de Janeiro a um grupo de ensino de Física da universidade nos possibilitou vislumbrar a ressignificação da função de um professor de Ciências (co-autor deste trabalho) por ele próprio, agora passando a incluir a pesquisa sobre a construção de conhecimento pelos alunos em sua prática como docente. A formação de grupos interinstitucionais para o planejamento de ações e de pesquisas tem-se mostrado produtiva para um trabalho de construção de conhecimentos a fim de subsidiar processos educativos na escola, ao mesmo tempo em que a universidade enriquece seu acervo de experiências validadas criticamente, podendo considerar seus resultados na formação inicial e continuada de professores. A participação ativa do professor num grupo de pesquisa na universidade o levou à reflexão sobre caminhos didáticos possíveis de serem descritos, analisados e comunicados a outros professores. A construção de uma pedagogia própria, levando em conta os modelos mentais dos alunos sobre temas básicos de Astronomia, e as mudanças promovidas a partir das aulas dadas, trouxeram amplas conseqüências sobre a pedagogia adotada pelo professor. Hoje a prática desse professor incorpora uma nova visão de ciência e formas alternativas de dialogar com os alunos, elementos indispensáveis a um pesquisador em Educação em Ciências.

Variáveis Cataclísmicas são sistemas binários cerrados compostos de uma anã vermelha que transfere matéria para uma anã branca, em sistemas não magnéticos ocorre a formação de um disco de acresção em torno da anã branca. V3885 Sgr é uma variável cataclísmica classificada como sendo do tipo nova-like. É apresentado um estudo espectrofotométrico de V3885 Sgr de alta resolução temporal feito na região do visível. A região observada é centrada em Ha e abrange também a linha de HeI 6678. O primeiro resultado obtido neste estudo é a determinação do período orbital a partir de medidas da velocidade radial da linha de Ha como sendo 0,20716071(22) dias, resolvendo inconsistências quanto a esse valor na literatura e definindo uma efeméride a longo prazo para o sistema. Com este período e as medidas de velocidade radial do perfil de linha de Ha foi construído um diagrama de massas, através do qual restringimos as massas das componentes estelares do sistema e limitamos a inclinação orbital do sistema. Foram construídos diagramas de Greenstein para as linhas de Ha e HeI, onde os espectros médios em cada intervalo de fase são representados lado a lado em escala de cinza, indicando a existência de uma emissão intensa proveniente da parte posterior do disco. A partir da tomografia Doppler obtivemos perfis de emissividade radial para o disco tanto para a linha de Ha como para HeI. Os resultados obtidos são comparados com os de outros sistemas estudados com a mesma técnica. Serão apresentados também resultados da tomografia de flickering para o sistema.

Arboviruses have been emerging in different parts of the world due to genetic changes in the virus, alteration of the host and vector population dynamics, or because of anthropogenic environmental factors. These viruses' capacity for adaptation is notable, as well as the likelihood of their emergence and establishment in new geographic areas. In Brazilian epidemiologic scenario, the most common arboviruses are DENV, CHIKV, and ZIKV, although others may spread in the country. Little is yet known of the impact of viral co-circulation, which would theoretically result in more intense viremia or other immunological alterations that could trigger autoimmune diseases, such as Guillain-Barré syndrome. The impact on morbidity and mortality intensifies as extensive epidemics lead to a high number of affected individuals, severe cases, and implications for health services, mainly due to the absence of treatment, vaccines, and effective prevention and control measures. RESUMO Notifica-se a emergência de arboviroses em diferentes regiões do planeta em decorrência de mudanças genéticas no vírus, alteração da dinâmica populacional de hospedeiros e vetores ou por fatores ambientais de origem antropogênica. É notável a capacidade de adaptação desses vírus e a possibilidade de emergirem e se estabelecerem em novas áreas geográficas. No contexto epidemiológico brasileiro, os arbovírus de maior circulação são DENV, CHIKV e ZIKV, embora existam outros com potencial de disseminação no País. O impacto da cocirculação viral ainda é pouco conhecido, a qual teoricamente resultaria em viremias mais intensas ou outras alterações imunológicas que poderiam ser o gatilho para doenças autoimunes, como a síndrome de Guillain-Barré. O impacto na morbidade e mortalidade se intensifica à medida que extensas epidemias pressupõem grande número de indivíduos acometidos, casos graves e implicações sobre os serviços de saúde, principalmente diante da ausência de tratamento, vacinas e medidas efetivas de prevenção e controle.

Introducción. Cada vez son más los hallazgos sobre la relación entre las concentraciones de vitamina D en el ser humano y diversas condiciones clínicas. Hay una gran cantidad de estudios que informan sobre dicha asociación, especialmente con complicaciones obstétricas, incluidas la preeclampsia y la diabetes mellitus de la gestación, entre otras, pero sus resultados todavía no son definitivos, por lo que se requieren estudios de intervención de calidad que confirmen la relación de la vitamina D con dichos resultados.Objetivo. Revisar la información plasmada en estudios en torno al papel de la vitamina D materna y el desarrollo de la preeclampsia.Materiales y métodos. La metodología usada siguió las recomendaciones de la guía Cochrane para la elaboración de revisiones sistemáticas y de la guía del grupo Meta-analysis of Observational Studies in Epidemiology (MOOSE) para los metaanálisis. La búsqueda incluyó estudios observacionales y ensayos clínicos controlados.Resultados. Los niveles bajos de vitamina D, medida con el examen de 25-hidroxivitamina D, son comunes en el embarazo. Los resultados de esta revisión sistemática y del metaanálisis sugieren una asociación inversa entre los niveles de vitamina D y el desarrollo de preeclampsia. Hubo heterogeneidad en los estudios en cuanto a su diseño, población y ubicación geográfica, así como a las definiciones de exposición y resultado. Los ensayos clínicos controlados aleatorizados se excluyeron del metaanálisis.Conclusión. Se encontró una asociación inversa que sugiere que, a mayores concentraciones de vitamina D, menor es la probabilidad de desarrollar preclampsia, a pesar de la heterogeneidad de la medida global en este tipo de análisis.

Chromosomenindividualität or Entmischung? The debate between Paolo Della Valle and Edmund B. Wilson.

PubMed

Volpone, Alessandro

2015-01-01

At the beginning of the twentieth century, the Italian cytologist Paolo Della Valle developed a theory of instable chromosomes (teoria dei cromosomi labili). He radically criticized the so-called Sutton-Boveri hypothesis (Martins and Martins, Genetics and Molecular Biology, 22:261-271, 1999), focusing on numerical constancy in the species and individuality. On the basis of bibliographical review and personal observations, he maintained that the chromosomes were neither stable bodies, nor permanent structures, but transitory cellular materials, resulting from the periodical rearrangement of the chromatin during the cell division. German and English-speaking biologists reacted. The paper shows some content of the argumentations used by Thomas H. Montgomery and especially Edmund B. Wilson. The discussion was characterized by the same data which is interpretedby different scholars in different ways. And the point is that no one of them had the decisive test to demonstrate his own point of view. Wilson simply invoked on his behalf a certain 'common sense', defending at least a 'high degree of constancy'. The debate waned along with the reception of Morgan's chromosome theory of heredity, but only the advent of molecular biology definitively stated the nature of chromosomes as permanent structures of the cell.

To review scientific literature to assess nutritional status of elderly patients with osteoarthritis in the last 16 years. This is an integrative literature review that included articles published in national and international journals indexed in PubMed, SciELO and BIREME. We selected 14 articles, and English language was predominant. The year of publication of articles ranged from 2006 to 2016, and most of papers were cross-sectional studies. To gather papers and for posterior evaluate, we used a validated data collection instrument and the included studies were critical analyzed by reading, gathering and analysis of articles. Studies suggested that there is a positive correlation between obesity and knee osteoarthritis. Obesity is one of the most important modifiable factors in worsening of osteoarthritis symptoms. RESUMO O objetivo da pesquisa foi revisar a produção científica referente à avaliação do estado nutricional de idosos com osteoartrite nos últimos 16 anos. Assim, o estudo foi uma revisão integrativa da literatura, realizada com a busca de artigos publicados em periódicos nacionais e internacionais indexados no PubMed, na SciELO e na BIREME. Foram selecionados 14 artigos, e o idioma inglês foi preponderante. O período de publicação dos artigos variou de 2006 a 2016, com predominância de estudos do tipo transversais. Para reunir os artigos e para posterior avaliação, foi utilizado um instrumento de coleta de dados validado, e as análises críticas dos estudos incluídos foram realizadas por meio da leitura, do agrupamento e da análise dos artigos. As pesquisas sugeriram que existe correlação positiva entre obesidade e osteoartrite de joelhos. Além disto, a obesidade é um dos fatores mais significativos e modificáveis no agravamento dos sintomas da osteoartrite.

Recent studies suggest that risperidone long-acting injection (RLAI) may be considered for controlling mood episodes in bipolar disorder patients who have relapsed due to medication nonadherence or failure to respond to standard therapies. Currently, no study has reported the usefulness of RLAI in youths with bipolar disorder. The aim of this study was to evaluate short-term effects of RLAI in the naturalistic treatment of early-onset bipolar disorder and its role in symptomatic remission and adherence to treatment. Nineteen early-onset bipolar disorder outpatients receiving RLAI were observed in a 6-month naturalistic study at the outpatient clinic of the Child and Adolescent Affective Disorders Program at the Institute of Psychiatry of the University of São Paulo, São Paulo, Brazil. All patients met DSM-IV criteria for bipolar disorder. Clinical response to RLAI was evaluated using the Children's Global Assessment Scale (CGAS) and Clinical Global Impressions scale (CGI) across 3 time periods: index time (T0), 8 weeks after (T1), and 24 weeks after (T2). These subjects were recruited from May 2008 to December 2009. Patients receiving RLAI presented considerable improvement in global functioning (CGAS: T0 = 20.6; T1 = 42.9; and T2 = 49.2) and clinical severity (CGI: T0 = 5.9; T1 = 3.9; and T2 = 3.4). Global CGI mean scores of clinical improvement were 2.2 at T1 and 2.4 at T2. There were no significant changes in laboratory measurements and weight throughout follow-up. RLAI was shown to be an alternative treatment for youths with bipolar disorder failing to respond to prior medication trials or with adherence problems. Further blind, randomized controlled studies are necessary to confirm these initial findings.

Proyecto para la medición sistemática de seeing en CASLEO

NASA Astrophysics Data System (ADS)

Fernández Lajus, E.; Forte, J. C.

La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

Este trabalho é parte integrante da pesquisa de mestrado acadêmico em ensino de ciências. Nele, busca-se apresentar os resultados da pesquisa realizada entre os 106 alunos do curso superior de tecnologia em automação industrial do Instituto Federal de Educação, Ciência e Tecnologia de São Paulo campus Cubatão, divididos em cinco turmas, duas no período matutino e três no período noturno. A análise dos resultados deste pré questionárioconstatou a falta de conhecimento básico dos discentes, sobre assuntos relacionados à astronomia, o que pode ser atribuído ao ineficiente processo de aprendizado pelo qual eles passaram tanto no ensino médio como no ensino fundamental, em escolas municipais, estaduais e particulares onde estudaram. No ensino de astronomia, têm-se diagnosticado constantemente diversas dificuldades conceituais tanto por parte de alunos como de professores de todas as áreas e níveis de ensino e poucos de fato a compreendem (ALBRECHT; VOELZKE, 2010). Demonstra-se as duas etapas concluídas do trabalho. A primeira etapa indica a análise dos conhecimentos prévios sobre conceitos astronômicos, através do questionário com 25 perguntas. A fim de corrigir as falhas constatadas, experimentalmente ministrou-se, externo ao conteúdo programático, um curso básico em astronomia, com diferentes estratégias de ensino, tais como, utilização de aulas expositivas dialogadas, recursos audiovisuais e palestras, para corrigir as dificuldades diagnosticadas. Essas estratégias de ensino se comprovaram adequadas às necessidades dos alunos e os conceitos foram finalmente compreendidos. Ao término do curso, completado o interstício de 120 dias, para caracterizar que houve a aprendizagem significativa, realizou-se uma nova pesquisa, quando, exatamente os mesmos 106 alunos responderam as mesmas 25 questões aplicadas na primeira etapa. Constata-se na segunda etapa, após análise, que em todas as questões, houve maior compreensão dos assuntos abordados e os alunos obtiveram uma melhora significativa no aprendizado dos conceitos relacionados à astronomia. Nota-se que a astronomia está presente e é elemento importante dos parâmetros curriculares nacionais e que há muito interesse por parte dos alunos com relação ao tema. Diante dos resultados obtidos no pós-curso, pode-se afirmar que o curso básico em astronomia, realizado na própria escola, mas externo ao conteúdo programático, proporcionou uma integração entre os alunos, estreitando os laços de amizade e do conhecimento entre eles não importando a turma ou o período pois a dificuldade inicial foi vencida por todos, com muita dedicação e comprometimento entre todos; hoje estes alunos podem seguramente continuar estudando estes conceitos de astronomia.

Streszczenie Przedmiotem artykułu jest przegląd prac badawczych dotyczących związku między cechami środowiska sąsiedzkiego a używaniem przez młodzież substancji psychoaktywnych. W pierwszej części pracy opisano sposoby definiowania obszaru środowiska sąsiedzkiego, w drugiej scharakteryzowano podstawy teoretyczne badań, w trzeciej – metody pomiaru cech środowiska sąsiedzkiego, a w czwartej przedstawiono wynik badań. Najczęściej przywoływanymi w badaniach teoriami, wyjaśniającymi związek między środowiskiem sąsiedzkim a zachowaniem młodzieży były teoria społecznej dezorganizacji oraz teoria kapitału społecznego. Odwoływano się ponadto do mechanizmów wpływu środowiska sąsiedzkiego na młodzież, takich jak: mechanizm norm i kolektywnej skuteczności, mechanizm zasobów instytucjonalnych, mechanizm relacji rodzinnych, mechanizm poczucia wspólnoty ze społeczności lokalną oraz model kolektywnego stylu życia. Najpowszechniej wykorzystywanym źródłem informacji o cechach środowiska były dane ze spisu powszechnego dotyczące społecznej i demograficznej charakterystyki mieszkańców. Stosowano również takie metody pomiaru, jak obserwacje w terenie, analiza dokumentacji oraz ankiety i wywiady z osobami badanymi, młodzieżą i rodzicami młodych ludzi. Wyniki badań potwierdziły, że cechy środowiska sąsiedzkiego mają bezpośredni i pośredni wpływ na sięganie przez młodzież po papierosy, alkohol i narkotyki. Stwierdzono, że znaczącym czynnikiem ryzyka jest charakterystyczna dla niekorzystnych środowisk łatwa dostępność substancji psychoaktywnych. Czynnikami chroniącymi są bezpieczeństwo w sąsiedztwie, kontrola społeczna oraz dostępność zasobów instytucjonalnych. Zaproponowane przez badaczy modele teoretyczne, odnoszące się do wpływu środowiska sąsiedzkiego na zachowanie młodzieży, wyznaczają obiecujące obszary badań. Zebrane dotychczas wyniki wskazują, że w działaniach profilaktycznych i interwencyjnych istotne znaczenie ma kształtowanie indywidualnych czynników chroniących młodzież przed negatywnym wpływem środowiska sąsiedzkiego, poprawa dostępności do zasobów materialnych oraz wzmacnianie kapitału społecznego młodych ludzi.

The current status of the Brazilian LANDSAT facilities operated by Instituto de Pesquisas Espaciais (INPE) and the results achieved during the period from October 1, 1984 to August 31, 1985 are presented. INPE's Receiving Station at Cuiaba, MT, operates normally the two tracking and receiving systems it has installed, the old one (1973) for Band S and the new one (February 1983) for dual S- and X-band. Both MSS and TM recording capabilities are functional. Support to the NASA Backup Plan for MSS data also remains active. Routine recordings are being made for LANDSAT-5 only, for both MSS and TM. Originally, MSS was recorded over the full acquisition range. However, since December, 1984, due to further reduction of operational expenses, both instruments are being recorded over Brazilian territory only.

An East-West one-dimensional radio interferometer array consisting of 5 parabolic dish antennas has been set-up at Cachoeira Paulista, Brazil (Longitude: 45°0'20″W, Latitude: 22°41'19″S) for observations of Sun and some of the strong sidereal sources by the Instituto Nacional de Pesquisas Espaciais (INPE), Brazil. This is Phase-1 of the proposed Brazilian Decimetre Array (BDA) and can be operated at any frequency in the range 1.2-1.7 GHz. The instrument is functional since November 2004 onwards at 1.6 GHz. The angular and temporal resolution at the above frequency range are ˜3' and 100 ms, respectively. We present here the initial solar observations carried out with this array.

How can the neutrino interact with the electromagnetic field?

Maxwell electrodynamics in the fixed Minkowski space-time background can be described in an equivalent way in a curved Riemannian geometry that depends on the electromagnetic field and that we call the electromagnetic metric (e-metric for short). After showing such geometric equivalence we investigate the possibility that new processes dependent on the e-metric are allowed. In particular, for very high values of the field, a direct coupling of uncharged particles to the electromagnetic field may appear.

Con el propósito de determinar propiedades dinámicas globales en sistemas triaxiales no integrables, utilizamos una nueva herramienta conocida como ``Mean Exponential Growth factor of Nearby Orbits'' (MEGNO), introducida por Cincotta y Simó (2000). Esta técnica no sólo resulta eficiente para investigar ambas componentes del espacio fase, regular y caótica, sino que también, provee una medida de la hiperbolicidad en el dominio caótico que coincide con la dada por el Lyapunov Characteristic Number (LCN). Previamente este método ha sido aplicado al estudio de modelos simples, y últimamente en el campo de la Mecánica Celeste, al estudio de sistemas planetarios extrasolares. En esta presentación, ilustraremos algunas de las propiedades más importantes del MEGNO, aplic& acute;andolo al potencial tridimensional de Stäckel perturbado.

To stimulate and awakening the interest of students of high school or elementary public schools in research and science through scientific initiation stages in the Postgraduate Program in Translational Surgery. To stimulate and awakening the interest of students of high school or elementary public schools in research and science through scientific initiation stages in the Postgraduate Program in Translational Surgery. The target audience for the development of scientific activities were students enrolled in mid-level course (second year initially) and have approval of their participation in this project by the school and by legal guardians. The inclusion criteria were: physical proximity to the higher education institution, signing the consent form by the legal responsible for the students, and for the board of the school unit and the researcher. Initially, students performed diagnostic evaluation about the prior knowledge of biology, science and scientific research. From there, the classes were prepared based on the result of this test, then started the activities of Junior Scientific Initiation in basic education. The school chosen for this initial phase of the pilot project was the State School Rui Bloem which has 13 classrooms for the second year of medium education in a total of 390 students. Of these, 160 (41%) were interested but only 16 (10%) were eligible to start the pilot project in Translational Surgery Laboratory of Unifesp. These students showed average yield of 50% in diagnostic test and should start the next training in cell and molecular biology laboratory and also to attend scientific meetings. In the initial phase of the project, was observed the great student interest in scientific career, but at the same time, a great need for improvement. The choice of public school was for access to university and proximity. In addition, these students have more shortcomings and deficiencies. But this does not mean that the fascination for scientific career cannot turn them into great researchers thus contributing to the economic, social and intellectual growth of our country through scientific research. Estimular e despertar o interesse dos alunos do ensino médio ou fundamental de escolas públicas na pesquisa e na ciência por meio de estágios de Iniciação Científica Junior no Programa de Pós-Graduação em Cirurgia Translacional da Unifesp. O público alvo para o desenvolvimento das atividades científicas foram alunos regularmente matriculados em curso de nível médio (segundos anos inicialmente) e que tivessem aprovação de sua participação pela direção da escola e responsáveis legais. Quanto aos critérios de inclusão: proximidade física com a instituição de ensino superior, assinatura do termo de consentimento pelos responsáveis dos alunos, pela diretoria da unidade escolar e pelo pesquisador. Inicialmente, os alunos realizaram avaliação diagnóstica acerca dos conhecimentos prévios de biologia, ciências e pesquisa científica. A partir daí as aulas eram elaboradas com base no resultado deste teste, para então iniciar as atividades de Iniciação Científica Junior. A escola escolhida para esta fase inicial do projeto piloto foi a Escola Estadual Rui Bloem que possui 13 salas de aula para o segundo ano do ensino médio com total de 390 alunos. Destes, 160 (41%) apresentaram-se interessados; porém, somente 16 (10%) foram elegíveis para iniciar o projeto piloto no Laboratório de Cirurgia Translacional da Unifesp. Estes alunos apresentaram rendimento médio de 50% na prova diagnóstica e deverão iniciar os próximos treinamentos no Laboratório de Biologia Celular e Molecular e também a frequentar as reuniões científicas. Nesta fase inicial houve interesse dos alunos do ensino médio e o projeto piloto apresentado estimulou e despertou interesse dos alunos de escola pública na pesquisa e na ciência. A escolha de uma escola pública foi para o acesso à universidade e proximidade. Além disso, esses alunos têm mais carências e deficiências. Mas isso não significa que o fascínio pela carreira científica não pode transformá-los em grandes pesquisadores, contribuindo assim para o crescimento econômico, social e intelectual do nosso país através da pesquisa científica.

To estimate the mid-point of an open-ended income category and to assess the impact of two equivalence scales on income-health associations. Data were obtained from the 2010 Brazilian Oral Health Survey (Pesquisa Nacional de Saúde Bucal--SBBrasil 2010). Income was converted from categorical to two continuous variables (per capita and equivalized) for each mid-point. The median mid-point was R$ 14,523.50 and the mean, R$ 24,507.10. When per capita income was applied, 53% of the population were below the poverty line, compared with 15% with equivalized income. The magnitude of income-health associations was similar for continuous income, but categorized equivalized income tended to decrease the strength of association.

This article presents the result of a research carried out in the first semester of 2013 with a group of 80 subjects from different education levels. In this research, we sought to investigate the earthly events that this group of people attributes to the phenomenon of lunar phases. For data collection we used semi-structured interviews guided by questions that aimed to keep the focus on subjects of the investigation. Interviews were recorded and transcribed, and the results were compared to scientific studies in the area after being quantitatively and qualitatively analyzed. Research data showed that the Moon and the phenomenon of lunar phases still fascinate and raise the interest of people. However, the lack of knowledge to find correct explanations to the phenomena involving the moon ends up originating a series of beliefs about its influence on earthly events. En este artículo se presenta el resultado de una investigación realizada en el primer semestre de 2013 con a un grupo de 80 individuos de distintos niveles de instrucción.

Como instrumento de colecta de datos, se emplearon entrevistas semiestructuradas guiadas por preguntas que trataban de mantener la atención de los entrevistados en el objeto investigado. Las entrevistas fueron grabadas y transcriptas, y los resultados, después de ser analizados cuantitatativa y cualitativamente, fueron confrontados con estudios científicos del área. Los datos de la investigación demuestran que la Luna y de sus fases continúan fascinando y despertando el interés de la población. Sin embargo, la falta de conocimientos para encontrar explicaciones correctas relacionadas a los fenómenos que ocurren con el astro acaba originando una serie de creencias en la población sobre su influencia en los sucesos terrestres.

To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone. Avaliar o papel da pesquisa de enterovírus no líquido cefalorraquidiano em comparação com o Escore de Meningite Bacteriana em crianças com meningite. Coorte retrospectiva, realizada pela análise de prontuários, incluindo pacientes pediátricos, com diagnóstico de meningite e atendidos em um hospital privado e terciário, localizado em São Paulo, entre 2011 e 2014. Foram excluídos os pacientes com doença crítica, púrpura, derivação ventricular ou neurocirurgia recente, imunossupressão, outra infecção bacteriana concomitante que necessitasse de antibioticoterapia parenteral e aqueles que receberam antibiótico 72 horas antes da punção lombar. Foram incluídos no estudo 503 pacientes. Destes, 64 foram excluídos e 94 não realizaram todos os exames para análise. Dos 345 pacientes restantes, 7 ficaram no Grupo de Meningite Bacteriana e 338 no Grupo de Meningite Asséptica. Não houve diferença estatística entre os grupos. Na análise do Escore de Meningite Bacteriana, dos 338 pacientes com possível meningite asséptica (culturas negativas), 121 deles tiveram um ou mais pontos para o Escore de Meningite Bacteriana, com valor de sensibilidade de 100%, especificidade de 64,2% e valor preditivo negativo de 100%. Dos 121 pacientes com Escore de Meningite Bacteriana positivo, 71% (86 pacientes) tiveram a pesquisa de enterovírus positiva no líquido cefalorraquidiano. A pesquisa de enterovírus no líquido cefalorraquidiano mostrou-se eficaz em diferenciar a meningite bacteriana da viral. Analisada junto com o Escore de Meningite Bacteriana, a especificidade foi maior em comparação ao Escore de Meningite Bacteriana isolado.

A estrutura local dos di-ureasils nao dopados esta modelada como grupos de dominios siliciosos com dimensoes nanometricas, estruturalmente correlacionados no seio de uma matriz rica em polimero. Neste trabalho mostra-se que os di-ureasils permitem o crescimento controlado de oxidos e oxidos-hidroxidos de ferro, incluindo a magnetite, maguemite, oxihidroxinitrato de ferro e ferrihidrite. O crescimento das nanoparticulas de ferrihidrite da-se em condicoes acidas a superficie dos dominios siliciosos, junto aos grupos carbonilo, que funcionam como pontos de nucleacao. Desse modo da-se uma nucleacao heterogenea, onde o tamanho das nanoparticulas depende da concentracao de ferro (entre 1 e 6% em massa), sendo a concentracao de particulas constante.

We present in this work the development of astronomy in Uruguay since the colony times up to the present, stressing in particular those aspects related to the formal as well as informal teaching of astronomy. The first antecedents of astronomical studies in our country go back to the beginnings of the XVIIIth century related to the scientific expeditions from Europe coming to our shores. The teaching of astronomy was generalized at the high school level as soon as the end of the XIXth century, while itsintroduction at the university level happened much later, around the middle of the last century. We analyze the current situation of this subject, its problems, and some measures to strengthen its development.

Employing Tropospheric Numerical Weather Prediction Model for High-Precision GNSS Positioning

NASA Astrophysics Data System (ADS)

Alves, Daniele; Gouveia, Tayna; Abreu, Pedro; Magário, Jackes

2014-05-01

In the past few years is increasing the necessity of realizing high accuracy positioning. In this sense, the spatial technologies have being widely used. The GNSS (Global Navigation Satellite System) has revolutionized the geodetic positioning activities. Among the existent methods one can emphasize the Precise Point Positioning (PPP) and network-based positioning. But, to get high accuracy employing these methods, mainly in real time, is indispensable to realize the atmospheric modeling (ionosphere and troposphere) accordingly. Related to troposphere, there are the empirical models (for example Saastamoinen and Hopfield). But when highly accuracy results (error of few centimeters) are desired, maybe these models are not appropriated to the Brazilian reality. In order to minimize this limitation arises the NWP (Numerical Weather Prediction) models. In Brazil the CPTEC/INPE (Center for Weather Prediction and Climate Studies / Brazilian Institute for Spatial Researches) provides a regional NWP model, currently used to produce Zenithal Tropospheric Delay (ZTD) predictions (http://satelite.cptec.inpe.br/zenital/). The actual version, called eta15km model, has a spatial resolution of 15 km and temporal resolution of 3 hours. In this paper the main goal is to accomplish experiments and analysis concerning the use of troposphere NWP model (eta15km model) in PPP and network-based positioning. Concerning PPP it was used data from dozens of stations over the Brazilian territory, including Amazon forest. The results obtained with NWP model were compared with Hopfield one. NWP model presented the best results in all experiments. Related to network-based positioning it was used data from GNSS/SP Network in São Paulo State, Brazil. This network presents the best configuration in the country to realize this kind of positioning. Actually the network is composed by twenty stations (http://www.fct.unesp.br/#!/pesquisa/grupos-de-estudo-e-pesquisa/gege//gnss-sp-network2789/). The results obtained employing NWP model also were compared to Hopfield one, and the results were very interesting. The theoretical concepts, experiments, results and analysis will be presented in this paper.

Six-Month Open-Label Follow-Up of Risperidone Long-Acting Injection Use in Pediatric Bipolar Disorder

PubMed Central

Wang, Yuan-Pang; Ferreira-Maia, Ana Paula; Cavalcanti, Ana Rosa S.; Fu-I, Lee

2013-01-01

Background: Recent studies suggest that risperidone long-acting injection (RLAI) may be considered for controlling mood episodes in bipolar disorder patients who have relapsed due to medication nonadherence or failure to respond to standard therapies. Currently, no study has reported the usefulness of RLAI in youths with bipolar disorder. The aim of this study was to evaluate short-term effects of RLAI in the naturalistic treatment of early-onset bipolar disorder and its role in symptomatic remission and adherence to treatment. Method: Nineteen early-onset bipolar disorder outpatients receiving RLAI were observed in a 6-month naturalistic study at the outpatient clinic of the Child and Adolescent Affective Disorders Program at the Institute of Psychiatry of the University of São Paulo, São Paulo, Brazil. All patients met DSM-IV criteria for bipolar disorder. Clinical response to RLAI was evaluated using the Children’s Global Assessment Scale (CGAS) and Clinical Global Impressions scale (CGI) across 3 time periods: index time (T0), 8 weeks after (T1), and 24 weeks after (T2). These subjects were recruited from May 2008 to December 2009. Results: Patients receiving RLAI presented considerable improvement in global functioning (CGAS: T0 = 20.6; T1 = 42.9; and T2 = 49.2) and clinical severity (CGI: T0 = 5.9; T1 = 3.9; and T2 = 3.4). Global CGI mean scores of clinical improvement were 2.2 at T1 and 2.4 at T2. There were no significant changes in laboratory measurements and weight throughout follow-up. Conclusions: RLAI was shown to be an alternative treatment for youths with bipolar disorder failing to respond to prior medication trials or with adherence problems. Further blind, randomized controlled studies are necessary to confirm these initial findings.

2012-01-01

The labor participation of Brazilian women has increased during the last few decades. According to the World Bank, the percentage of Brazilian women participating in the labor market rose from 20% in the early 1970s to 65% (for women between 16 and 64 years of age) in 2009. The fertility profile has also changed, the fertility rate has decreased from 6.2 in 1960 to 1.9 in 2009, below the replacement rate, according to the World Bank. This paper will present Brazilian fertility trends during the previous (20(th)) and present (21(st)) centuries and, emphasize the importance of individual profiles for fertility decisions. This work uses Brazilian data from PNAD (Pesquisa Nacional de Amostra por Domicilios) to understand the cause of this relationship and to predict the consequences of these choices on women's economic development.

Los costos de la atención médica pueden alcanzar niveles tales que marginen a algunos pacientes de los beneficios del avance científico y tecnológico. Las razones de estos elevados costos son diversas y en la mayoría de los casos no está en manos de los médicos moderarlos. En este escrito se proponen algunas acciones que los médicos podemos realizar para disminuir los costos de la atención médica. La magnitud del ahorro que se puede alcanzar con estas medidas es modesta, puesto que la mayor parte de los costos no dependen de los médicos, pero se trata de ofrecer nuestra contribución. Evitar todo lo superfluo: no más medicamentos ni estudios que los estrictamente necesarios, sin medicina defensiva; y no ceder ante la presión de pacientes y familiares para que se prescriban pruebas o medicamentos inútiles.

Se presentan nuevos resultados sobre la expansión del remanente de la supernova de Tycho a lo largo de un intervalo de 10.9 años, comparando nuevas observaciones tomadas con el VLA a 1375 y 1635 MHz durante 1994 y 1995, con observaciones previas realizadas entre 1983 y 1984 (Dickel y col. ~1991 AJ 101, 2151), usando las mismas configuraciones, anchos de banda, calibradores y tiempos de integración. El coeficiente de expansión se calcula para sectores radiales de 4o de ancho cada uno, ajustando la correlación cruzada de las derivadas de los perfiles promedio para cada época. A partir de la expansión medida, se estima el índice (parámetro de expansión) de la ley potencial R∝ tm como m≡ d ln R/d ln t . Este valor se compara con coeficientes teóricos para diferentes fases evolutivas de remanentes de supernova.

Mathematical Physics in Italy in the XIX Century: The Theory of Elasticity

NASA Astrophysics Data System (ADS)

Capecchi, Danilo

In the second half of the nineteenth century there was in Italy an important group of mathematicians who focused their attention on mathematical physics. The most prominent of them were Enrico Betti, Eugenio Beltrami, Gregorio Ricci-Curbastro and some others (Vito Volterra, Carlo Somigliana and Tullio Levi Civita) whose activity persevered for many years in the twentieth century. In this article, I will write about the contribution of this group to the theory of elasticity. The best representative writing on continuum mechanics and elasticity as theories of mathematical physics is presented in the book Teoria della elasticità by Enrico Betti. The book is interesting not only for the particular results found but also for its structure which became paradigmatic for the development of subsequent texts on elasticity, not only those in Italian. Betti's interest was concentrated on the mathematical aspects of a physical theory. Physical principles are not discussed; they are only exposed in the most formal way possible. The objective is to arrive, without discussing epistemological or empirical problems, at the formulation and solution of differential equations that rule elasticity, as had become classic in the emerging mathematical physics. Beltrami wrote no complete books on elasticity; however, his contribution to this field was perhaps more original than that of Betti. A similar consideration holds true for Volterra and Somigliana.

Ortiz Benavides, Fedra Lorena

El proposito de la investigacion fue evaluar la efectividad de una actividad de aprendizaje basado en la argumentacion dialogica en linea y su incidencia en el desarrollo de competencias cientificas. Se fundamenta en la teoria del aprendizaje socio cultural de Vigotsky (1984), los principios del diseno instruccional de la cognicion situada por Hung y Der-Thang (2001) y como estrategia se aplico la argumentacion dialogica utilizando el Modelo Argumentativo de Toulmin MAT (1984). El diseno experimental comparo dos grupos de estudiantes A y B en el curso virtual de Biotecnologia. El grupo A (experimental) desarrollo la discusion a partir de la estrategia disenada para este estudio y el grupo B (control) realizo la discusion desde las actividades tradicionales. El desarrollo de la competencia argumentativa se valoro con el instrumento de evaluacion para argumentacion dialogica en linea propuesta por Clark y Sampson (2008). La evaluacion de las competencias cientificas se realizo a partir de una postprueba. Los datos fueron analizados con pruebas estadisticas no parametricas. Los resultados de la investigacion, indicaron diferencias significativas en el nivel de la competencia argumental en el grupo experimental en comparacion al grupo control. Igualmente se demostro que existe una relacion positiva entre el nivel de desarrollo de la competencia argumentativa y el nivel de desarrollo de las competencias cientificas.

In this study, we evaluated the psychometric properties of the items to measure the work-family conflict and the time use for personal care and leisure, included in the baseline questionnaire of the Longitudinal Study of Adult Health (ELSA-Brazil). We evaluated temporal stability (7-14 days) using kappa statistic and the validity of the construct by the correlation of Kendall's tau with other variables. Test-retest stability was discreet to moderate and the correlations were compatible with the underlying theory. Future studies in the context of ELSA-Brazil and in other populations will complement the assessment of its relevance. RESUMO Neste estudo, avaliamos as propriedades psicométricas dos itens para mensurar o conflito trabalho-família e o uso do tempo para cuidado pessoal e lazer, incluídos no questionário da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Foram avaliadas a estabilidade temporal (7-14 dias) utilizando estatística kappa e a validade do construto pela correlação tau de Kendall com outras variáveis. A estabilidade teste-reteste foi discreta a moderada e as correlações, compatíveis com a teoria subjacente. Estudos futuros no contexto do ELSA-Brasil e em outras populações complementarão a avaliação da sua pertinência.

To describe the Reference Centers for Special Immunobiologicals and evaluate their implementation considering formal regulations. We conducted a program evaluation, of evaluative research type. From August 2011 to January 2012, a questionnaire was applied to the 42 Reference Centers for Special Immunobiologicals existing in the Country, approaching the structure, human resources, and developed activities dimensions. We conducted a descriptive analysis of data and used a clustering for binary data with the squared Euclidean distance, by the farthest neighbor method, to aggregate services with similar features. We observed great diversity among the services in the three dimensions. The clustering resulted in five service profiles, named according to their characteristics. 1) Best structure: 12 Reference Centers for Special Immunobiologicals with the highest proportion of services with the minimum of rooms recommended, purpose-built vaccine refrigerators, preventive maintenance of the cold chain, and oxygen source. 2) Immunobiologicals distributor: six Reference Centers for Special Immunobiologicals that distributed more than applied immunogens; no doctor present for more than half of the working hours and no purpose-built vaccine refrigerators . 3) Incipient implementation: five Reference Centers for Special Immunobiologicals with inadequate structure, such as absence of purpose-built vaccine refrigerators, preventive maintenance of the cold chain and oxygen source; none had computer. 4) Vaccination rooms: 13 Reference Centers for Special Immunobiologicals, everyone did routine immunization, most participated in vaccination campaigns. 5) Teaching and research: six services, all inserted into teaching hospitals, developed researches and received trainees; most had doctors in more than half of the working hours. The evaluation of the Reference Centers for Special Immunobiologicals implementation was based on the profiles found and considered the official regulations: services categorized as "better structure" and "teaching and research" were considered implemented; "immunobiologicals distributor" and "vaccination room" services, partially implemented, and the ones with the "incipient implementation" profile, not implemented. The results of this evaluation can contribute to the reformulation of the services, considering the current context. Descrever os Centros de Referência para Imunobiológicos Especiais e avaliar sua implantação considerando as regulamentações formais. Foi realizada uma avaliação de programa, tipo pesquisa avaliativa. De agosto de 2011 a janeiro de 2012, foi aplicado questionário aos responsáveis pelos 42 Centros de Referência para Imunobiológicos Especiais existentes no País, abordando as dimensões estrutura, recursos humanos e atividades desenvolvidas. Foi feita análise descritiva dos dados e utilizado agrupamento para dados binários com uso da distância euclidiana quadrática, pelo método do vizinho mais distante, para agregar serviços com características semelhantes. Observou-se grande diversidade entre os serviços nas três dimensões. O agrupamento resultou em cinco perfis de serviços, denominados de acordo com suas características. 1) Melhor estrutura: 12 Centros de Referência para Imunobiológicos Especiais com a maior proporção de serviços com o mínimo de salas preconizado, câmaras de vacinas, manutenção preventiva da rede de frio e fonte de oxigênio. 2) Dispensador de imunobiológicos: seis Centros de Referência para Imunobiológicos Especiais que mais dispensavam do que aplicavam imunógenos; sem médico presente por mais da metade do expediente do serviço e sem câmara de vacinas. 3) Implantação incipiente: cinco Centros de Referência para Imunobiológicos Especiais com estrutura inadequada, como ausência de câmaras de vacinas, de manutenção preventiva da rede de frio e de fonte de oxigênio; nenhum possuía computador. 4) Sala de vacinas: 13 Centros de Referência para Imunobiológicos Especiais, todos faziam imunização de rotina, a maioria participava de campanhas de vacinação. 5) Ensino e pesquisa: seis serviços, todos inseridos em hospitais de ensino, desenvolviam pesquisas e recebiam estagiários; a maioria possuía médicos em mais da metade do expediente. A avaliação de implantação dos Centros de Referência para Imunobiológicos Especiais baseou-se nos perfis encontrados e considerou as regulamentações oficiais: os serviços categorizados como "melhor estrutura" e "ensino e pesquisa" foram considerados implantados; os serviços "dispensador de imunobiológicos" e "sala de vacinas", parcialmente implantados e os do perfil "implantação incipiente", não implantados. Os resultados dessa avaliação podem contribuir para a reformulação dos serviços, considerando o contexto atual.

The role of tuberculosis as a public health care priority and the availability of diagnostic tools to evaluate functional status (spirometry, plethysmography, and DLCO determination), arterial blood gases, capacity to perform exercise, lesions (chest X-ray and CT), and quality of life justify the effort to consider what needs to be done when patients have completed their treatment. To our knowledge, no review has ever evaluated this topic in a comprehensive manner. Our objective was to review the available evidence on this topic and draw conclusions regarding the future role of the "post-tuberculosis treatment" phase, which will potentially affect several million cases every year. We carried out a non-systematic literature review based on a PubMed search using specific keywords (various combinations of the terms "tuberculosis", "rehabilitation", "multidrug-resistant tuberculosis", "pulmonary disease", "obstructive lung disease", and "lung volume measurements"). The reference lists of the most important studies were retrieved in order to improve the sensitivity of the search. Manuscripts written in English, Spanish, and Russian were selected. The main areas of interest were tuberculosis sequelae following tuberculosis diagnosis and treatment; "destroyed lung"; functional evaluation of sequelae; pulmonary rehabilitation interventions (physiotherapy, long-term oxygen therapy, and ventilation); and multidrug-resistant tuberculosis.The evidence found suggests that tuberculosis is definitively responsible for functional sequelae, primarily causing an obstructive pattern on spirometry (but also restrictive and mixed patterns), and that there is a rationale for pulmonary rehabilitation. We also provide a list of variables that should be discussed in future studies on pulmonary rehabilitation in patients with post-tuberculosis sequelae. RESUMO O papel da tuberculose como uma prioridade de saúde pública e a disponibilidade de ferramentas diagnósticas para avaliar o estado funcional (espirometria, pletismografia e DLCO), a gasometria arterial, a capacidade de realizar exercícios, as lesões (radiografia de tórax e TC) e a qualidade de vida justificam o esforço de se considerar o que deve ser feito quando os pacientes completam seu tratamento. Até onde sabemos, nenhuma revisão avaliou esse tópico de forma abrangente. Nosso objetivo foi revisar as evidências disponíveis e obter algumas conclusões sobre o futuro papel da fase de "tratamento pós-tuberculose", que irá potencialmente impactar milhões de casos todos os anos. Realizou-se uma revisão não sistemática da literatura tendo como base uma pesquisa no PubMed usando palavras-chave específicas (várias combinações dos termos "tuberculose", "reabilitação", "tuberculose multirresistente", "doença pulmonar", "doença pulmonar obstrutiva", e "medidas de volume pulmonar"). As listas de referências dos artigos principais foram recuperadas para melhorar a sensibilidade da busca. Foram selecionados manuscritos escritos em inglês, espanhol e russo. As principais áreas de interesse foram sequelas de tuberculose após diagnóstico e tratamento; "pulmão destruído"; avaliação funcional das sequelas; intervenções de reabilitação pulmonar (fisioterapia, oxigenoterapia de longo prazo e ventilação); e tuberculose multirresistente. As evidências encontradas sugerem que a tuberculose é definitivamente responsável por sequelas funcionais, principalmente causando um padrão obstrutivo na espirometria (mas também padrões restritivos e mistos) e que há razão para a reabilitação pulmonar. Fornecemos também uma lista de variáveis a serem discutidas em futuros estudos sobre reabilitação pulmonar em pacientes com sequelas pós-tuberculose.

Um supressor de fundo térmico para a câmara infravermelha CamIV

NASA Astrophysics Data System (ADS)

Jablonski, F.; Laporte, R.

2003-08-01

O ângulo sólido subtendido pelos pixels na câmara infravermelha do NexGal (CamIV) que operamos no OPD/LNA contém contribuições provenientes do sistema de coleta de fluxo propriamente dito - sendo esta a parte que interessa para as medidas astronômicas - e contribuições da obstrução central, sistema de suporte do espelho secundário e região exterior à pupila de entrada do telescópio. Estas últimas contribuições são devi-das à emissão de corpo negro à temperatura ambiente e aumentam exponencialmente para comprimentos de onda maiores que 2 micra (banda K, no infravermelho próximo). Embora a resultante pode ser quantificada e subtraída dos sinais relevantes, sua variância se adiciona à variância do sinal, e pode ser facilmente a contribuição domi-nante para a incerteza final das medidas, tornando ineficiente o processo de extração de informação e degradando a sensibilidade da câmara. A maneira clássica de resolver esse problema em sistemas ópticos que operam no infravermelho, onde os efeitos da emissão térmica do ambiente são importantes, é restringir o ângulo sólido subtendido pelos pixels individuais exclusivamente aos raios provenientes do sistema óptico. Para tanto, projeta-se uma imagem real, bastante reduzida, da pupila de entrada do sistema óptico num anteparo que transmita para o sistema de imageamento só o que interessa, bloqueando as contribuições das bordas externas à pupila de entrada, obstrução central do telescópio e sistema de suporte. Como a projeção é realizada em ambiente criogênico, a contribuição térmica espúria é efetivamente eliminada. Nós optamos por um sistema do tipo Offner para implementar na prática esta função. Trata-se de um sistema baseado em espelhos esféricos, bastante compacto e ajustado por construção. A opção por espelhos do mesmo material que o sistema de suporte (Alumínio) minimiza a dilatação diferencial, crítica nesse tipo de aplicação. Apresentamos as soluções detalhadas do projeto óptico-mecânico, bem como uma análise de flexões e desempenho em termos de qualidade de imagem.

Transitions in Fertility for Brazilian Women: An Analysis of Impact Factors

Madalozzo, Regina

2012-01-01

The labor participation of Brazilian women has increased during the last few decades. According to the World Bank, the percentage of Brazilian women participating in the labor market rose from 20% in the early 1970s to 65% (for women between 16 and 64 years of age) in 2009. The fertility profile has also changed, the fertility rate has decreased from 6.2 in 1960 to 1.9 in 2009, below the replacement rate, according to the World Bank. This paper will present Brazilian fertility trends during the previous (20th) and present (21st) centuries and, emphasize the importance of individual profiles for fertility decisions. This work uses Brazilian data from PNAD (Pesquisa Nacional de Amostra por Domicilios) to understand the cause of this relationship and to predict the consequences of these choices on women’s economic development.

Yoshizumi, M. T.; Caldas, L. V. E.

2010-07-01

A ring-shaped monitor ionization chamber was developed at the Instituto de Pesquisas Energéticas e Nucleares. This ionization chamber presents an entrance window of aluminized polyester foil. The guard ring and collecting electrode are made of graphite coated Lucite plates. The main difference between this new ionization chamber and commercial monitor chambers is its ring-shaped design. The new monitor chamber has a central hole, allowing the passage of the direct radiation beam without attenuation; only the penumbra radiation is measured by the sensitive volume. This kind of ionization chamber design has already been tested, but using aluminium electrodes. By changing the electrode material from aluminium to a graphite coating, an improvement in the chamber response stability was expected. The pre-operational tests, as saturation curve, recombination loss and polarity effect showed satisfactory results. The repeatability and the long-term stability tests were also evaluated, showing good agreement with international recommendations.

Educational inequality by race in Brazil, 1982-2007: structural changes and shifts in racial classification.

Marteleto, Leticia J

2012-02-01

Despite overwhelming improvements in educational levels and opportunity during the past three decades, educational disadvantages associated with race still persist in Brazil. Using the nationally representative Pesquisa Nacional de Amostra por Domicílio (PNAD) data from 1982 and 1987 to 2007, this study investigates educational inequalities between white, pardo (mixed-race), and black Brazilians over the 25-year period. Although the educational advantage of whites persisted during this period, I find that the significance of race as it relates to education changed. By 2007, those identified as blacks and pardos became more similar in their schooling levels, whereas in the past, blacks had greater disadvantages. I test two possible explanations for this shift: structural changes and shifts in racial classification. I find evidence for both. I discuss the findings in light of the recent race-based affirmative action policies being implemented in Brazilian universities.

Sporotrichosis is a mycosis caused by Sporothrix schenckii. The most affected animal is the cat; it has played an important role in the zoonotic transmission of this disease, especially in Rio de Janeiro, Brazil, since 1998. In order to evaluate the treatment of feline sporotrichosis with potassium iodide, an observational cohort was conducted in 48 cats with sporotrichosis at Instituto de Pesquisa Clínica Evandro Chagas, Fiocruz. All cats received potassium iodide capsules, 2.5 mg/kg to 20 mg/kg q24h. The cure rate was 47.9%, treatment failure was 37.5%, treatment abandonment was 10.4% and death was 4.2%. Clinical adverse effects were observed in 52.1% of the cases. Thirteen cats had a mild increase in hepatic transaminase levels during the treatment, six of them presented clinical signs suggestive of hepatotoxicity. Compared to previous studies with itraconazole and iodide in saturated solution, potassium iodide capsules are an alternative for feline sporotrichosis treatment.

Study and optimization of the macroscopic electrical response of carbon based nanocomposites for advanced applications

Silva, Jaime Pedro Oliveira da

A presente tese centrou-se no estudo da resposta da constante dieletrica e condutividade eletrica em materiais compositos nos quais o reforco tinha uma elevada proporcao entre comprimento e diametro. O objeto de estudo foi o efeito de um reforco com uma elevada razao entre comprimento e diametro, concentracao e orientacao na resposta eletrica e dieletrica de um composito. Estes compositos tem uma grande importancia no desenvolvimento de materiais para sensores e atuadores. Num primeiro momento da dissertacao, explorou-se a resposta da constante dieletrica de um composito constituido por nanotubos de carbono como reforco e uma matriz polimerica. Verificou-se que um aumento da razao entre comprimento e diametro do reforco tem o efeito de aumentar a constante dieletrica do composito para uma igual fracao volumetrica de reforco. Constatou-se tambem que materiais na fase nematica demonstram uma constante dieletrica mais baixa quando comparados com materiais onde o reforco esta distribuido aleatoriamente. Ficou ainda demonstrado nesta dissertacao que materiais na fase nematica com razoes entre o comprimento e diametro diferentes a constante dieletrica segue uma lei de potencia. Numa segunda fase do trabalho, foi explorada a condutividade de nanocompositos polimericos reforcados com nanotubos de carbono, atraves de um modelo baseado em cilindros impenetraveis. Ficou demonstrado que o modelo e apropriado para descrever a condutividade eletrica de um nanocomposito polimerico reforcado com nanotubos. As simulacoes desenvolvidas demonstram que, aumentando a razao entre o comprimento e o diametro dos nanotubos de carbono, aumenta a condutividade eletrica do nanocomposito. No entanto, verifica-se que aumentando a anisotropia diminui a condutividade, sendo este efeito mais evidente para fracoes volumetricas maiores. Nesta dissertacao comprovou-se ainda que uma microestrutura gerada por um algoritmo de empacotamento sequencial pode ser descrita por um grafo aleatorio e que a condutividade num composito reforcado com nanofibras de carbono pode ser descrito por uma rede de Bethe. Atraves do uso da teoria das redes complexas, chegou-se a uma expressao para o limite de percolacao e, do mesmo modo, demonstrou-se que “hopping” entre fibras adjacentes resulta numa expressao que corresponde a um regime de desordem fraca. No trabalho desenvolvido tambem foi calculado os expoentes criticos, atraves da teoria das redes, para um sistema 3D composto por cilindros impenetraveis com uma interacao de curto alcance, demonstrando que os expoentes criticos estao relacionados por uma relacao de hiperescala comum para 3D e nao pertencem a mesma classe de universalidade como a percolacao numa rede. A aplicacao do modelo desenvolvido a compositos de epoxy reforcada, com diferentes metodos de dispersao de nanofibras de carbono, revelou que os metodos de dispersao usados para preparar os compositos tem uma forte influencia nas propriedades eletricas que podem ser capturadas pelo modelo. Neste contexto, ficou ainda demonstrado que a condutividade eletrica pode ser descrita por um regime de desordem fraca, isto ´e, um regime onde todas as conexoes fibra-fibra participam na condutividade do composito. O modelo desenvolvido foi aplicado igualmente a compositos de poly (vinylidene fluoride) reforcado com nanotubos de carbono com diferentes tratamentos de termicos de oxidacao. Verificou-se que os tratamentos de superficie aumentam o limite de percolacao e diminuem a condutividade. Nesta dissertacao provamos ainda que a condutividade do composito pode ser atribuida a um mecanismo de “hopping”, fortemente afetado pelos tratamentos de superficie dos reforcos.

To assess the development and implementation of permanent education action. Quantitative-qualitative research based on action research in three phases (diagnosis of reality, implementation of activity and evaluation), performed with health professionals and managers of basic health units. The evaluation was on the perception of changes immediately following the activity and after 120 days. In the first phase, 110 professionals took part, 36.4% of whom indicated the existence of groups for older adults at work. In the second phase, 98 professionals participated, pointing out interferences of the group in the life of older adults, items of importance and facilitation in forming groups and developing reality-based activities. The third phase showed, in the quantitative analysis, positive impact of the training, and in the qualitative analysis, reassessment of groups, greater knowledge and confidence in managing groups and increased respect for older adults. Permanent education opens pathways for the construction of differentiated care for older adults based on respect and health promotion.

To identifyevidences of the influence of nursing workload on the occurrence of adverse events (AE) in adult patients admitted to the intensive care unit (ICU). A systematic literature review was conducted in the databases MEDLINE, CINAHL, LILACS, SciELO, BDENF, and Cochrane from studies in English, Portuguese, or Spanish, published by 2015. The analyzed AE were infection, pressure ulcer (PU), patient falls, and medication errors. Of 594 potential studies, eight comprised the final sample of the review. TheNursing Activities Score (NAS; 37.5%) and the Therapeutic Intervention Scoring System(TISS; 37.5%) were the instruments most frequently used for assessing nursing workload. Six studies (75.0%) identified the influence of work overload in events of infection, PU, and medicationerrors. An investigation found that the NAS was a protective factor for PU. The nursing workload required by patients in the ICU influenced the occurrence of AE, and nurses must monitor this variable daily to ensure proper sizing of staff and safety of care.

Food is a key factor both in prevention and in promoting human health. Among the functional food are highlighted probiotics and prebiotics. Patent databases are the main source of technological information about innovation worldwide, providing extensive library for research sector. Perform mapping in the main patent databases about pre and probiotics, seeking relevant information regarding the use of biotechnology, nanotechnology and genetic engineering in the production of these foods. Electronic consultation was conducted (online) in the main public databases of patents in Brazil (INPI), United States (USPTO) and the European Patent Bank (EPO). The research involved the period from January 2014 to July 2015, being used in the title fields and summary of patents, the following descriptors in INPI "prebiotic", "prebiotic" "probiotics", "probiotic" and the USPTO and EPO: "prebiotic", "prebiotics", "probiotic", "probiotics". This search haven't found any deposit at the brazilian patents website (INPI) in this period; US Patent &Trademark Office had registered 60 titles in patents and the European Patent Office (EPO) showed 10 documents on the issue. Information technology offered by genetic engineering, biotechnology and nanotechnology deposited in the form of titles and abstracts of patents in relation to early nutritional intervention as functional foods, has increasingly required to decrease the risks and control the progression of health problems. But, the existing summaries, although attractive and promising in this sense, are still incipient to recommend them safely as a therapeutic tool. Therefore, they should be seen more as diet elements and healthy lifestyles. A alimentação é fator primordial tanto na prevenção quanto na promoção para a saúde humana. Dentre os alimentos funcionais destacam-se os probióticos e prebióticos. Os bancos de dados de patentes representam a maior fonte de informação tecnológica acerca de inovação em nível mundial, provendo vasta biblioteca para o setor de pesquisa. Realizar mapeamento nas principais bases de dados de patentes relacionada aos pré e probióticos buscando informações relevantes com relação ao uso da biotecnologia, nanotecnologia e engenharia genética na produção desses alimentos. Foi realizada consulta eletrônica (online) nas principais bases de dados públicas de patentes do Brasil (INPI), Estados Unidos da América (USPTO) e o Banco de Patentes Europeu (EPO). A pesquisa envolveu o período de janeiro de 2014 a julho 2015, sendo utilizado nos campos de título e resumo das patentes, os seguintes descritores no INPI: "prebiótico", "prebióticos" "probiótico", "probióticos" e no USPTO e EPO: "prebiotic", "prebiotics", "probiotic", "probiotics". Não foram observados, no INPI, depósitos de residentes (empresas ou universidades). Já no USPTO foram detectados 60 depósitos e no EPO 10 títulos de interesse à pesquisa. A tecnologia da informação ofertada pela engenharia genética, biotecnologia e nanotecnologia depositada na forma de títulos e resumos das patentes em relação à intervenção nutricional precoce como alimentos funcionais, tem cada vez mais pretendido diminuir os riscos e controlar a progressão de agravos à saúde. Mas, os resumos existentes, embora atraentes e promissores neste sentido, ainda são incipientes para recomendá-los de forma segura como ferramenta terapêutica. Portanto, devem ser encarados mais como integrantes de dieta e estilos de vida saudáveis.

To present a high school insertion pilot project in post graduate programs (PPG) and discuss the mechanisms for the formation of leaders in science. This study presents a review and pilot project. Bibliographic search occurred in sites of CAPES, MEC, SciELO and library of virtual books from January/ 2014 to February/2015. The pilot is in PPG-Medicine III Translational Surgery/UNIFESP and Pathophysiology and Surgical Sciences / UERJ. The junior undergraduate students (ICj) came from public school and develop scientific activities: scientific meetings, graduation and inclusion in research projects. The evaluation will occur at the end of one year, with the results essays, reports and participation in scientific events. In Brazil, one of the main challenges of education is the high average years of study. The PNPG (2011-2020) shows the insertion of basic education in all PPG. In the Pathophysiology and Surgical Sciences/UERJ there are currently 11 high school students who have followed the scientific meetings and are being prepared for the inclusion in research projects. There was 30% of absence, owing to the high school hours. This result and the experience allow creating future alternatives to enhance the integration project. The leadership in science is formed from a complex relationship between basic education and investment in research. PPG-Medicine III courses follow the vanguard with initiatives focused on scientific and technological development. Thus, projects involving basic education students represent promoter model and environment leaders. Apresentar um projeto piloto de inserção do ensino médio em programas de pós-graduação (PPG) e discutir os mecanismos para a formação de líderes em ciência. Realizou-se um estudo de revisão e apresentação de piloto. A busca bibliográfica ocorreu nos sites da CAPES, MEC, Scielo e biblioteca de livros virtuais, de janeiro/2014 a fevereiro/2015. O piloto ocorre nos PPG-Medicina III em Cirurgia Translacional/UNIFESP e Fisiopatologia e Ciências Cirúrgicas/UERJ. Os alunos de iniciação científica júnior (ICj) são oriundos de escola pública e desenvolvem atividades científicas: participação em reuniões científicas, graduação e inserção nos projetos de pesquisa. A avaliação ocorrerá ao final de um ano, com redações dos resultados, relatórios e participações em eventos científicos. No Brasil, um dos principais desafios da educação é a alta média de anos de estudo. O PNPG (2011-2020) apresenta a inserção da educação básica em todos os PPG. Na Fisiopatologia e Ciências Cirúrgicas/UERJ há atualmente 11 alunos do ensino médio, que já acompanharam as reuniões científicas e preparam-se para a inserção em projetos de pesquisa. Houve 30% de desistência, devido à alta carga horária escolar. Esse resultado e a experiência vivenciada permite criar alternativas futuras para aprimorar o projeto de inserção. A liderança em ciências é formada a partir de uma complexa relação entre educação básica e investimentos na pesquisa. Cursos de PPG-Medicina III seguem na vanguarda com iniciativas focadas no desenvolvimento científico e tecnológico. Assim, projetos envolvendo alunos da educação básica representam modelo e ambiente promotor de líderes.

To analyze the prevalence of medicine use by the Brazilian population and its distribution according to sociodemographic factors. Study using data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide household survey of a representative sample of the Brazilian urban population. The data were collected between September 2013 and February 2014. The overall use of medicines, defined as the use of any medicine, use of medicines for treating chronic medical conditions and for acute health conditions, was evaluated. The independent variables included gender, age group, socioeconomic position, and region of Brazil. Analyzes included prevalence calculations, 95% confidence intervals (95%CI) and Pearson Chi-square tests to evaluate the differences between groups, considering a 5% level of significance. The prevalence of medicines use was 50.7% (95%CI 49.3-52.2), with 39.3% (95%CI 37.5-41.1) accounting for men and 61.0% (95%CI 59.3-62.6) for women. Medicines use was observed to increase with increasing age, except among children within the zero to four years age group. The lowest prevalence for medicines use was found among those with a low socioeconomic position and those who reside in the North region of Brazil. The prevalence of medicine use to treat chronic diseases was 24.3% (95%CI 23.3-25.4), whereas it was 33.7% (95%CI 32.1-35.4) for treating acute diseases. We found extensive variability in the prevalence of medicines use across regions of Brazil. The poorest regions (North, Northeast, and Midwest) have a lower prevalence of medicines use to treat chronic diseases, indicating the need to minimize inequalities in access to medicines within the country. Analisar a prevalência do uso de medicamentos pela população brasileira e sua distribuição segundo aspectos sociodemográficos. Estudo com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), pesquisa nacional de base populacional, realizada entre setembro de 2013 e fevereiro de 2014 em residências de municípios urbanos. Avaliou-se o uso de todos os medicamentos (global), uso de medicamentos para doenças crônicas e uso de medicamentos para doenças agudas. As variáveis independentes utilizadas foram sexo, idade, classificação econômica e região do País. Foram calculados prevalências e intervalos de confiança de 95% (IC95%) e aplicado teste Qui-quadrado de Pearson para avaliação das diferenças entre os grupos, considerando o nível de significância de 5%. A prevalência global de uso de medicamentos foi de 50,7% (IC95% 49,3-52,2), sendo 39,3% (IC95% 37,5-41,1) no sexo masculino e 61,0% (IC95% 59,3-62,6) no sexo feminino. Observou-se aumento nas prevalências de uso com a idade (exceto de zero a quatro anos). As menores prevalências de uso ocorreram no grupo mais pobre e na região Norte do País. A prevalência de uso de medicamentos para doenças crônicas foi de 24,3% (IC95% 23,3-25,4) e para doenças agudas foi de 33,7% (IC95% 32,1-35,4). Existe grande variabilidade nas prevalências globais de uso de medicamentos por regiões brasileiras. As regiões consideradas mais pobres (Norte, Nordeste e Centro-Oeste) apresentam menores prevalências de uso de medicamentos para doenças crônicas, o que indica a necessidade de minimizar as desigualdades no acesso aos medicamentos dentro do País.

Yeast strains capable of direct fermentation of manioc starch were developed by hybridizing strains of Saccharomyces diastaticus and Saccharomyces cerevisiae. Hybrids were evaluated for speed of alcohol production, and yields and speed of formation of glycoamylase. Up to 6% solutions of Lintner starch could be fermented directly with about 80% conversion to alcohol. Pretreatment of crude 40% manioc starch suspensions with alpha-amylase, followed by fermentations with a starch-fermenting yeast strain, permitted accumulation of 12% ethanol within three days. Starch conversion was almost 100%. A fragment of DNA was cloned from S. diastaticus using the yeast-E. coli shuttle vector, YEp13, andmore » was used to transform a strain of S. cerevisiae to a starch-fermenting state. Supported by National Science Foundation grant INT 7927328 and National Institutes of Health grant GM 27860.

Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years.

This study presents the first results of the National Abortion Survey (PNA, Pesquisa Nacional de Aborto), a household random sample survey fielded in 2010 covering urban women in Brazil aged 18 to 39 years. The PNA combined two techniques, interviewer-administered questionnaires and self-administered ballot box questionnaires. The results of PNA show that at the end of their reproductive health one in five women has performed an abortion, with abortions being more frequent in the main reproductive ages, that is, from 18 to 29 years old. No relevant differentiation was observed in the practice of abortion among religious groups, but abortion was found to be more common among people with lower education. The use of medical drugs to induce abortion occurred in half of the abortions, and post-abortion hospitalization was observed among approximately half of the women who aborted. Such results lead to conclude that abortion is a priority in the Brazilian public health agenda.

This paper summarizes several cases of metallurgical failure analysis of surgical implants conducted at the Laboratory of Failure Analysis, Instituto de Pesquisas Tecnológicas (IPT), in Brazil. Failures with two stainless steel femoral compression plates, one stainless steel femoral nail plate, one Ti-6Al-4V alloy maxillary reconstruction plate, and five Nitinol wires were investigated. The results showed that the implants were not in accordance with ISO standards and presented evidence of corrosion-assisted fracture. Furthermore, some of the implants presented manufacturing/processing defects which also contributed to their premature failure. Implantation of materials that are not biocompatible may cause several types of adverse effects in the human body and lead to premature implant failure. A review of prevailing health legislation is needed in Brazil, along with the adoption of regulatory mechanisms to assure the quality of surgical implants on the market, providing for compulsory procedures in the reporting and investigation of surgical implants which have failed in service.

ABSTRACT This paper describes the development process of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines) based on an integrated approach to pharmaceutical services, science, technology and innovation. It starts by contextualizing health and development in Brazil and features elements of the National Policy for Science, Technology and Innovation in Health in Brazil and the National Policy for Pharmaceutical Services. On presenting pharmaceutical policy guidelines, it stresses the lack of nationwide data. This survey, commissioned by the Brazilian Ministry of Health, has two components: household survey and evaluation of pharmaceutical services in primary care. The findings point to perspectives that represent, besides the enhancement of public policy for pharmaceutical services and public health, results of government action aimed at developing the economic and industrial health care complex to improve the health conditions of the Brazilian population.

Na década de 90 iniciaram-se vários programas para a pesquisa de matéria escura na Galáxia usando o efeito de microlentes gravitacionais. Entre os projetos mais bem conhecidos podemos mencionar o OGLE (Optical Gravitational Lensing Experiment) e o MACHO (MAssive Compact Halo Objects). A estratégia usada por eles consiste em fazer fotometria de banda larga (normalmente B, R e I) de um grande número de estrelas (dezenas de milhões) tão freqüentemente quanto possí vel e por longos perí odos de tempo (anos). Uma tal sistemática de observação, além de descobrir inúmeras lentes gravitacionais, é também muito apropriada para a descoberta de estrelas variáveis. De fato, inúmeras novas variáveis de vários tipos foram descobertas como subproduto. Exemplos podem ser encontrados nos endereços http://bulge.princeton.edu/~ogle/ e http://wwwmacho.mcmaster.ca/. As variáveis cataclí smicas eruptivas (novas clássicas, novas recorrentes e novas anãs) são objetos que apresentam variabilidade de grande amplitude com escalas de tempo de dias a centenas de dias e, por esta razão, devem ter sido detectadas em grande número nestes "surveys". Para testar esta possibilidade nós procuramos nos dados do OGLE por tais sistemas e o presente trabalho mostra os resultados desta pesquisa. Os objetos foram selecionados entre as variáveis detectadas usando a amplitude de variação de brilho como critério principal. Este critério forneceu 13756 objetos, sendo 2169 na direção da Grande Nuvem de Magalhães, 1162 na direção da Pequena Nuvem de Magalhães e o restante na direção do Bojo Galáctico. A análise foi feita inspecionando-se visualmente cada curva de luz por erupções com as características acima mencionadas. Os resultados obtidos podem ser sumarizados como: descoberta de duas novas clássicas e 33 novas anãs. Além disso, pode-se mencionar a identificação de candidatas a outros tipos de variáveis como: estrelas simbióticas, RV Tauri, R Coronae Borealis, Miras, etc.

Guidelines for Clinical Practice: Hymenoptera sting allergy in children: 2017 update

PubMed

2017-10-01

Las picaduras por himenópteros son frecuentes en la infancia. La mayoría producen reacciones locales, consecuencia de un mecanismo inflamatorio, no alérgico, no tienen progresión y se resuelven con simples medidas terapéuticas. Las reacciones más extensas, generalmente, están asociadas a mecanismos alérgicos, mediados por inmunoglobulina E. Su máxima expresión, la anafilaxia, presenta síntomas cutáneos, respiratorios, cardiovasculares, digestivos y/o neurológicos, con riesgo de muerte. La prevalencia de anafilaxia en pacientes con mastocitosis sistémica es más alta. La familia Hymenoptera, que incluye hormigas coloradas, abejas y avispas, es la causante de las picaduras de mayor riesgo, potencialmente fatales. Los pilares del diagnóstico son la historia clínica, la identificación del insecto, y las pruebas diagnósticas cutáneas y/o in vitro interpretadas por el especialista en Alergia e Inmunología. La inmunoterapia con veneno es el tratamiento de elección para prevenir reacciones anafilácticas por picaduras de himenópteros.

Cabañas Galán, B.

La interpretación de las transformaciones químicas que se producen en la atmósfera requiere un profundo conocimiento de la cinética, productos y mecanismos de reacción de las posibles interacciones que pueden ocurrir entre las distintas especies presentes en ella. Información cuantitativa de este tipo es un prerrequisito para la construcción de modelos numéricos adecuados que expliquen el comportamiento químico-físico de la atmósfera. Esta información se obtiene a partir de experimentos realizados en laboratorios y por tanto independiente de medidas atmosféricas, por lo que los modelos atmosféricos derivados de ellos, pueden usarse para diagnosticar y predecir adecuadamente el comportamiento atmosférico. En esta exposición se recogen las técnicas experimentales más extendidas para la obtención de datos cinéticos así como los métodos de análisis de datos más utilizados en el estudio de las distintas reacciones de interés atmosférico. Se analizan sus características generales así como su adecuación a los distintos tipos de reacciones.

Dual-porosity modeling of groundwater recharge: testing a quick calibration using in situ moisture measurements, Areuse River Delta, Switzerland

NASA Astrophysics Data System (ADS)

Alaoui, Abdallah; Eugster, Werner

A simple method for calibrating the dual-porosity MACRO model via in situ TDR measurements during a brief infiltration run (2.8 h) is proposed with the aim of estimating local groundwater recharge (GR). The recharge was modeled firstly by considering the entire 3 m of unsaturated soil, and secondly by considering only the topsoil to the zero-flux plane (0-0.70 m). The modeled recharge was compared against the GR obtained from field measurements. Measured GR was 313 mm during a 1-year period (15 October 1990-15 October 1991). The best simulation results were obtained when considering the entire unsaturated soil under equilibrium conditions excluding the macropore flow effect (330 mm), whereas under non-equilibrium conditions GR was overestimated (378 mm). Sensitivity analyses showed that the investigation of the topsoil is sufficient in estimating local GR in this case, since the water stored below this depth appears to be below the typical rooting depth of the vegetation and is not available for evapotranspiration. The modeled recharge under equilibrium conditions for the 0.7-m-topsoil layer was found to be 364 mm, which is in acceptable agreement with measurements. Une méthode simple pour la calibration du modèle à double porosité MACRO par des mesures TDR in situ durant un bref essai d'infiltration (2.8 h) a été proposée pour l'estimation locale de la recharge de la nappe (RN). La RN a été d'abord simulée en tenant compte de toute la zone non saturée (3 m) et ensuite, en considérant uniquement la couverture du sol entre zéro et le plan du flux nul (0.70 m). La RN simulée a été comparée à la RN observée. La RN mesurée durant une année (15 octobre 1990-15 octobre 1991) était de 313 mm. Les meilleures simulations ont été obtenues en tenant compte de toute la zone non saturée sous les conditions d'équilibre excluant le flux préférentiel (330 mm). Sous les conditions de non équilibre, la RN a été surestimée (378 mm). Les analyses de sensitivité ont montré que l'investigation de la couverture du sol est suffisante pour l'estimation locale de la RN du fait que l'eau traversant le plan du flux nul se trouverait sous la zone des racines et échapperait à l'évapotranspiration. La RN simulée sur les 0.70 m du sol sous les conditions d'équilibre était de 364 mm, ce qui est comparable aux mesures. Se propone un método sencillo para calibrar el modelo de doble porosidad "MACRO" mediante medidas in-situ obtenidas por TDR durante un breve ensayo de infiltración (2,8 horas), con el objetivo de estimar la recarga local al acuífero. Ésta ha sido modelada de dos formas: considerando los 3 m de suelo no saturado y empleando sólo desde la capa superior hasta el plano de flujo nulo (de 0 a 0,70 m). Se compara la recarga modelada con la recarga local medida en campo, la cual fue de 313 mm durante un ciclo anual (del 15 de octubre de 1990 al 15 de octubre de 1991). Las mejores simulaciones corresponden a la hipótesis de columna entera no saturada en condiciones de equilibrio, excluyendo el efecto de macroporos (valor de 330 mm), mientras que el resultado obtenido para condiciones de no equilibrio en la recarga local está sobreestimado (378 mm). Los análisis de sensibilidad muestran que la investigación del horizonte superior del suelo es suficiente para estimar la recarga local en este caso, ya que el agua almacenada por debajo de esta profundidad parece estar fuera del alcance típico de las raíces de la vegetación y no puede ser evapotranspirada. La recarga modelada en condiciones de equilibrio para la capa superior de 0,70 m de espesor es de 364 mm, valor aceptable respecto a las medidas.

Obesity can affect the thorax, diaphragm, and alterations in respiratory function even if the lungs are within normality. The respiratory compliance is very reduced by the increase in fat mass. To evaluate the effect of the physical therapeutic respiratory exercises on the thoracoabdominal mobility of obese individuals in pre-bariatric surgery. Cross-sectional and descriptive study, which used the cirtometry (axillary, xiphoid and abdominal) to evaluate the mobility of 74 individuals, 27 men and 47 women, in pre-bariatric surgery, assisted by the team EMAD, after eight weeks of physiotherapy, following a protocol of exercises, reevaluating and compared the measures pre and post intervention. Had positive correlation abdominal mobility in the total volume of all participants (p=0.010) and also for all the measures in the measurement of residual volume in three levels (p=0.000). Comparing genders, in total volume, cirtometry abdominal greater for women (p=0.015) when compared to men and residual volume, significance for either men or women in all measurements (p=0.000). Obese patients that underwent the physiotherapeutic treatment during the preoperative period, had pré respiratory dynamics improved by the increase in the mobility of the chest cavity and by the improvement of respiratory conscience. A obesidade pode afetar o tórax e o diafragma, determinando alterações na função respiratória, mesmo quando os pulmões se apresentam dentro da normalidade. A complacência respiratória é muito reduzida pelo aumento de massa gordurosa. Avaliar o efeito de exercícios fisioterapêuticos respiratórios sobre a mobilidade torácica de indivíduos obesos no pré-operatório de cirurgia bariátrica. Estudo transversal e descritivo, que utilizou a cirtometria (axilar, xifoide e abdominal) para avaliar a mobilidade de 74 indivíduos, 27 homens e 47 mulheres, em pré-operatório de cirurgia bariátrica, assistidos pela equipe EMAD, após oito semanas de fisioterapia, seguindo um protocolo de exercícios, reavaliando e comparado as medidas pré e pós a intervenção. Apresentaram correlação positiva a mobilidade abdominal no volume total de todos os participantes (p=0,010) e também para todas as medidas na mensuração do volume residual nos três níveis (p=0,000). Comparando os sexos, no volume total, a cirtometria abdominal maior das mulheres (p=0,015) quando comparada a dos homens e no volume residual, significância tanto para os homens quanto para as mulheres em todas as mensurações (p=0,000). Obesos que se submeteram ao tratamento fisioterapêutico durante o período pré-operatório, tiveram dinâmica respiratória melhorada pelo aumento da mobilidade da caixa torácica e pela melhora da consciência respiratória.

To estimate the healthy life expectancy at 60 years by sex and Federated States and to investigate geographical inequalities by socioeconomic status. Healthy life expectancy was estimated by the Sullivan method, based on the information of the National Survey on Health, 2013. Three criteria were adopted for the definition of "unhealthy state": self-assessment of bad health, functionality for performing the activities of daily living, and the presence of noncommunicable disease with intense degree of limitation. The indicator of socioeconomic status was built based on the number of goods at household and educational level of the head of household. To analyze the geographical inequalities and socioeconomic level, inequality measures were calculated, such as the ratio, the difference, and the angular coefficient. Healthy life expectancy among men ranged from 13.8 (Alagoas) to 20.9 (Espírito Santo) for the self-assessment criterion of bad health. Among women, the corresponding estimates were always higher and ranged from 14.9 (Maranhão) to 22.2 (São Paulo). As to the ratio of inequality by Federated State, the medians were always higher for healthy life expectancy than for life expectancy, regardless of the definition adopted for healthy state. Regarding the differences per Federated State, the healthy life expectancy was seven years higher in one state than in another. By socioeconomic status, differences of three and four years were found, approximately, between the last and first fifth, for men and women, respectively. Despite the association of the mortality indicators with living conditions, the inequalities are even more pronounced when the welfare and the limitations in usual activities are considered, showing the necessity to promote actions and programs to reduce the socio-spatial gradient. Estimar a esperança de vida saudável aos 60 anos por sexo e Unidade da Federação e investigar as desigualdades geográficas e por nível socioeconômico. A esperança de vida saudável foi estimada pelo método de Sullivan, com base nas informações da Pesquisa Nacional de Saúde, 2013. Foram adotados três critérios para definição de estado "não saudável": autoavaliação de saúde ruim, funcionalidade para realização das atividades da vida diária, e presença de doença crônica não transmissível com grau intenso de limitação. O indicador de nível socioeconômico foi construído com base no número de bens no domicílio e grau de escolaridade do responsável. Para analisar as desigualdades geográficas e por nível socioeconômico, foram calculadas medidas de desigualdade, como a razão, a diferença e o coeficiente angular. A esperança de vida saudável entre os homens variou de 13,8 (Alagoas) a 20,9 (Espírito Santo) para o critério de autoavaliação de saúde ruim. Entre as mulheres, as estimativas correspondentes foram sempre mais altas e variaram de 14,9 (Maranhão) a 22,2 (São Paulo). Quanto à razão de desigualdades por Unidade da Federação, as medianas foram sempre maiores para a esperança de vida saudável do que para a esperança de vida, independentemente da definição adotada para estado saudável. Quanto às diferenças por Unidade da Federação, a esperança de vida saudável chegou a ser sete anos maior em um estado do que em outro. Por nível socioeconômico, foram encontradas diferenças de três e quatro anos, aproximadamente, entre os últimos e primeiro quintos, para homens e mulheres, respectivamente. Além de os indicadores de mortalidade estarem associados às condições de vida, as desigualdades são ainda mais pronunciadas quando o bem-estar e as limitações nas atividades habituais são levados em consideração, mostrando a necessidade de promover ações e programas para diminuir o gradiente socioespacial.

To analyze scopes and limits of the use of participatory methodology of evaluation with municipal health managers and administrators. Qualitative research with health policymakers and managers of the Comissão Intergestores Regional (CIR - Regional Interagency Commission) of a health region of the state of Sao Paulo in Brazil. Representatives from seven member cities participated in seven workshops facilitated by the researchers, with the aim of assessing a specific problem of the care line, which would be used as a tracer of the system integrality. The analysis of the collected empirical material was based on the hermeneutic-dialectic methodology and aimed at the evaluation of the applied participatory methodology, according to its capacity of promoting a process of assessment capable to be used as a support for municipal management. With the participatory approach of evaluation, we were able to promote in-depth discussions with the group, especially related to the construction of integral care and to the inclusion of the user's perspective in decision-making, linked to the search for solution to concrete problems of managers. By joint exploration, the possibility of using data from electronic information systems was opened, as well as information coming directly from the users of the services, to enhance discussions and negotiations between partners. The participants were disbelievers of the replication potential of this type of evaluation without the direct monitoring of the academy, given the difficulty of organizing the process in everyday life, already taken by emergency and political issues. Evaluations of programs and services carried out within the Regional Interagency Commission, starting from the local interest and facilitating the involvement of its members by the use of participatory methodologies, can contribute to the construction of integral care. To the extent that the act of evaluating stay invested with greater significance to the local actors, its involvement with the evaluations at the federal level can also be stimulated. Analisar alcances e limites do uso de metodologia participativa de avaliação junto a gestores e gerentes municipais de saúde. Pesquisa qualitativa com gestores e gerentes de saúde da Comissão Intergestores Regional de uma região de saúde do estado de São Paulo. Representantes de sete municípios membros participaram de sete oficinas facilitadas pelos pesquisadores, com o objetivo de avaliar um problema específico da linha de cuidados sob a perspectiva da integralidade. A análise do material empírico coletado baseou-se na metodologia hermenêutica-dialética e visou a avaliação da metodologia participativa aplicada, segundo sua capacidade de promover um processo de avaliação passível de ser utilizado como suporte à gestão municipal. Com a abordagem participativa de avaliação, foi possível promover debates em profundidade com o grupo, principalmente relacionados à construção da integralidade da atenção e à inclusão da perspectiva do usuário na tomada de decisão, de forma vinculada à busca de solução para problemas concretos dos gestores. Mediante a exploração conjunta, foi aberta a possibilidade de utilização de dados advindos dos sistemas eletrônicos de informação, bem como de informações advindas diretamente dos usuários dos serviços, para enriquecer debates e negociações entre parceiros. Os participantes se mostraram descrentes do potencial de replicação deste tipo de avaliação sem o acompanhamento direto da academia, dada a dificuldade de organização do processo no cotidiano, já tomado por questões emergenciais e políticas. Avaliações de programas e serviços realizadas no âmbito da Comissão Intergestores Regional, partindo do interesse local e facilitando o envolvimento de seus membros pelo uso de metodologias participativas, podem contribuir para a construção da integralidade do cuidado. Na medida em que o ato de avaliar fique investido de maior significado para os atores locais, seu envolvimento com as avaliações em nível federal poderá ser também estimulado.

To identify intervention categories encountered by physical therapists working in aquatic therapy with disabled children, using the International Classification of Functioning, Disability and Health-Children and Youth (ICF-CY). Aquatic physical therapists were asked to describe concepts related to the functioning of disabled children and their contextual factors. Data were collected in three rounds using the Delphi technique. All answers were translated ('linked') to the ICF-CY and analyzed to determine the degree of consensus. Answers were linked and organized into four diagnostic groups. Overall, in the four groups, 41 Body Functions, 8 Body Structures, 36 Activities and Participation, and 6 Environmental Factors categories were identified as intervention targets. In addition, 8 Environmental Factors that influence aquatic physical therapy were identified. This study highlights the variety of intervention categories available to aquatic physical therapists when treating children in the water.

A cooperative renewable energy project is underway between the U.S. Department of Energy (through the National Renewable Energy Laboratory, NREL), and the Federal Republic of Brazil (through the Centro de Pesquisas de Energia Eletrica, CEPEL). The objectives of this joint US/Brazilian program are to establish technical, institutional, and economic confidence in using renewable energy systems to meet the needs of the people of rural Brazil, to build ongoing partnerships beneficial to both countries, and to demonstrate the potential for large-scale rural electrification through the use of renewable energy systems. Phase 1 of this program resulted in the deployment of moremore » than 700 photovoltaic (PV) electric lighting systems in the Brazilian states of Pernambuco and Ceara. Phase 2 of the program extends the pilot project into six additional Brazilian states and demonstrates a wider variety of stand-alone end uses, including the use of wind electric power generation for selected sites and applications. Additionally, Phase 2 also includes the development of two hybrid village power systems, including one comprising PV, wind, battery, and diesel power sources. This paper focuses on this hybrid system, which is located in the Amazon River delta.« less

Effects of correlated hybridization in the single-impurity Anderson model

NASA Astrophysics Data System (ADS)

Líbero, Valter; Veiga, Rodrigo

2013-03-01

The development of new materials often dependents on the theoretical foundations which study the microscopic matter, i.e., the way atoms interact and create distinct configurations. Among the interesting materials, those with partially filled d or f orbitals immersed in nonmagnetic metals have been described by the Anderson model, which takes into account Coulomb correlation (U) when a local level (energy Ed) is doubled occupied, and an electronic hybridization between local levels and conduction band states. In addition, here we include a correlated hybridization term, which depends on the local-level occupation number involved. This term breaks particle-hole symmetry (even when U + 2Ed = 0), enhances charge fluctuations on local levels and as a consequence strongly modifies the crossover between the Hamiltonian fixed-points, even suppressing one or other. We exemplify these behaviors showing data obtained from the Numerical Renormalization Group (NRG) computation for the impurity temperature-dependent specific heat, entropy and magnetic susceptibility. The interleaving procedure is used to recover the continuum spectrum after the NRG-logarithmic discretization of the conduction band. Fundação de Amparo à Pesquisa do Estado de São Paulo - FAPESP.

Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years. PMID:24675917

The paper discusses the results of research into user satisfaction in three healthcare facilities at Oswaldo Cruz Foundation in Rio de Janeiro. The analysis is based on the concepts of user satisfaction and responsiveness. Perceptions and opinions of outpatients from Instituto de Pesquisa Evandro Chagas, Instituto Fernandes Figueira and Centro de Saúde Escola Germano Sinval Faria were investigated. Intention samples were drawn for each institution and a total of 1.339 valid questionnaires were obtained. The study found that patients are satisfied with healthcare at Fiocruz, especially with health professionals. Nevertheless, restroom hygiene and privacy during consultations were less well evaluated. The improvement of these aspects depends not only on financial and technological investments but on changes in organizational culture. The first part of the paper discusses the literature on user satisfaction and responsiveness, with the definition of the categories that guided the study. The methodology is then presented as well as the four health services dimensions assessed - dignity, agility, facilities and communication - and the results are analyzed.

Racial Inequality in Education in Brazil: A Twins Fixed-Effects Approach.

PubMed

Marteleto, Letícia J; Dondero, Molly

2016-08-01

Racial disparities in education in Brazil (and elsewhere) are well documented. Because this research typically examines educational variation between individuals in different families, however, it cannot disentangle whether racial differences in education are due to racial discrimination or to structural differences in unobserved neighborhood and family characteristics. To address this common data limitation, we use an innovative within-family twin approach that takes advantage of the large sample of Brazilian adolescent twins classified as different races in the 1982 and 1987-2009 Pesquisa Nacional por Amostra de Domicílios. We first examine the contexts within which adolescent twins in the same family are labeled as different races to determine the characteristics of families crossing racial boundaries. Then, as a way to hold constant shared unobserved and observed neighborhood and family characteristics, we use twins fixed-effects models to assess whether racial disparities in education exist between twins and whether such disparities vary by gender. We find that even under this stringent test of racial inequality, the nonwhite educational disadvantage persists and is especially pronounced for nonwhite adolescent boys.

The study Pesquisa Dimensões Sociais das Desigualdades (PDSD) (Social Dimensions of Inequalities) involves 12,423 randomly selected Brazilian men and women aged 18 years old or more from urban and rural areas of the five Brazilian regions, and the information collected included the SF-36 as a measure of health-related quality of life. This provided a unique opportunity to develop age and gender-adjusted normative data for the Brazilian population. Brazilian men scored substantially higher than women on all eight domains and the two summary component scales of the SF-36. Brazilians scored less than their international counterparts on almost all of SF-36 domains and both summary component scales, except on general health status (US), pain (UK) and vitality (Australia, US and Canada). The differences in the SF-36 scores between age groups, genders and countries confirm that these Brazilian norms are necessary for comparative purposes. The data will be useful for assessing the health status of the general population and of patient populations, and the effect of interventions on health-related quality of life.

Development, health, and international policy: the research and innovation dimension.

This text main objective is to discuss development and health from the perspective of the influence of global health governance, using as the tracer the dimension of research, development, and innovation policies in health, which relate to both important inputs for the health system, like drugs and medicines, vaccines, diagnostic reagents, and equipment, and innovative concepts and practices for the improvement of health systems and public health. The authors examine the two main macro-processes that influence development and health: the post-2015 Development Agenda and the process under way in the World Health Organization concerning research and development, intellectual property, and access to health inputs. The article concludes, first, that much remains to be done for the Agenda to truly represent a coherent and viable international political pact, and that the two macro-processes related to innovation in health need to be streamlined. But this requires democratization of participation by the main stakeholders - patients and the general population of the poorest countries - since this is the only way to overcome a "zero sum" result in the clash in the current debates among member State representatives. Resumo: O objetivo central deste texto é discutir desenvolvimento e saúde sob a ótica da influência da governança da saúde global, utilizando como traçador a dimensão das políticas de pesquisa, desenvolvimento e inovação em saúde, que se referem, de um lado, a insumos importantes para o sistema de saúde - como fármacos e medicamentos, vacinas, reativos para diagnóstico e equipamentos e, de outro, a conceitos e práticas inovadoras para o aperfeiçoamento dos sistemas de saúde e da saúde pública. Examina os dois principais macroprocessos que influenciam o desenvolvimento e a saúde: a Agenda do Desenvolvimento para o pós-2015 e o processo sobre pesquisa e desenvolvimento, propriedade intelectual e acesso a insumos em saúde em curso na Organização Mundial da Saúde. Conclui que muito há que ser feito para que a referida Agenda possa representar um pacto político internacional coerente e viável, e que os dois macroprocessos relacionados com a inovação em saúde precisam ser agilizados, mas para isto torna-se necessária a democratização da participação dos maiores interessados - os pacientes e, de modo geral, a população dos países mais pobres - pois só desta maneira será superada a "soma zero" em que se encontra o embate entre os representantes de Estados-membros nos debates atuais.

The incidence of microcephaly in Brazil in 2015 was 20 times higher than in previous years. Congenital microcephaly is associated with genetic factors and several causative agents. Epidemiological data suggest that microcephaly cases in Brazil might be associated with the introduction of Zika virus. We aimed to detect and sequence the Zika virus genome in amniotic fluid samples of two pregnant women in Brazil whose fetuses were diagnosed with microcephaly. In this case study, amniotic fluid samples from two pregnant women from the state of Paraíba in Brazil whose fetuses had been diagnosed with microcephaly were obtained, on the recommendation of the Brazilian health authorities, by ultrasound-guided transabdominal amniocentesis at 28 weeks' gestation. The women had presented at 18 weeks' and 10 weeks' gestation, respectively, with clinical manifestations that could have been symptoms of Zika virus infection, including fever, myalgia, and rash. After the amniotic fluid samples were centrifuged, DNA and RNA were extracted from the purified virus particles before the viral genome was identified by quantitative reverse transcription PCR and viral metagenomic next-generation sequencing. Phylogenetic reconstruction and investigation of recombination events were done by comparing the Brazilian Zika virus genome with sequences from other Zika strains and from flaviviruses that occur in similar regions in Brazil. We detected the Zika virus genome in the amniotic fluid of both pregnant women. The virus was not detected in their urine or serum. Tests for dengue virus, chikungunya virus, Toxoplasma gondii, rubella virus, cytomegalovirus, herpes simplex virus, HIV, Treponema pallidum, and parvovirus B19 were all negative. After sequencing of the complete genome of the Brazilian Zika virus isolated from patient 1, phylogenetic analyses showed that the virus shares 97-100% of its genomic identity with lineages isolated during an outbreak in French Polynesia in 2013, and that in both envelope and NS5 genomic regions, it clustered with sequences from North and South America, southeast Asia, and the Pacific. After assessing the possibility of recombination events between the Zika virus and other flaviviruses, we ruled out the hypothesis that the Brazilian Zika virus genome is a recombinant strain with other mosquito-borne flaviviruses. These findings strengthen the putative association between Zika virus and cases of microcephaly in neonates in Brazil. Moreover, our results suggest that the virus can cross the placental barrier. As a result, Zika virus should be considered as a potential infectious agent for human fetuses. Pathogenesis studies that confirm the tropism of Zika virus for neuronal cells are warranted.

2015-07-01

The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP). We honored Professor Alejandro Szanto de Toledo, who completed fifty years of scientific activities at the University of Sao Paulo (USP). He dedicated most of his life to the development of experimental nuclear physics in the country. We had a special session where his life and achievements were remembered. The organization of the XXXVII RTFNB 2014 was one more step in a big effort to build in our part of the world a community of physicists engaged in the difficult problems of fundamental and applied nuclear physics. The international contacts bring new knowledge, provide reference framework and stimulate collaborations that are essential for a true participation in the scientific frontier. The Editors, the Organizing Committee and the whole Brazilian community of nuclear physicists were pleased and very grateful to the visitors that were together with us during the five days in Maresias.

Cell-derived microvesicles (MVs) are vesicles released from activated or apoptotic cells. However, the levels of MVs in myocardial infarction have been found inconsistent in researches. To assess the association between MVs and myocardial infarction by conducting a meta-analysis. A systematic literature search on PubMed, Embase, Cochran, Google Scholar electronic database was conducted. Comparison of the MVs levels between myocardial infarction patients and healthy persons were included in our study. Standard Mean Difference (SMD) and 95% confidence interval (CI) in groups were calculated and meta-analyzed. 11 studies with a total of 436 participants were included. Compared with the health persons, AMVs [SMD = 3.65, 95% CI (1.03, 6.27)], PMVs [SMD = 2.88, 95% CI (1.82, 3.93),] and EMVs [SMD = 2.73, 95% CI (1.13, 4.34)], levels were higher in patients with myocardial infarction. However, LMVs levels [SMD = 0.73, 95% CI (-0.57, 2.03)] were not changed significantly in patients with myocardial infarction. AMVs, PMVs and EMVs might be potential biomarkers for myocardial infarction. As microvesículas derivadas de células (MVs) são vesículas liberadas de células ativadas ou apoptóticas. No entanto, os níveis de MVs no infarto do miocárdio foram encontrados inconsistentes nas pesquisas. Avaliar a associação entre MV e infarto do miocárdio por meio de uma meta-análise.

The concentrations of 3 oxides and 29 elements in 7 National Bureau of Standards (NBS) and 3 Instituto de Pesquisas Techno16gicas (IPT) reference clay samples were etermined by instrumental neutron activation analysis. The analytical work was designed to test the homogeneity of constituents in three new NBS reference clays, NBS-97b, NBS-98b, and NBS-679. The analyses of variance of 276 sets of data for these three standards show that the constituents are distributed homogeneously among bottles of samples for 94 percent of the sets of data. Three of the reference samples (NBS-97, NBS-97a, and NBS-97b) are flint clays; four of the samples (NBS-98, NBS-98a, NBS-98b, and IPT-32) are plastic clays, and three of the samples (NBS-679, IPT-28, and IPT-42) are miscellaneous clays (both sedimentary and residual). Seven clays are predominantly kaolinite; the other three clays contain illite and kaolinite in the approximate ratio 3:2. Seven clays contain quartz as the major nonclay mineral. The mineralogy of the flint and plastic clays from Missouri (NBS-97a and NBS-98a) differs markedly from that of the flint and plastic clays from Pennsylvania (NBS-97, NBS-97b, NBS-98, and NBS-98b). The flint clay NBS-97 has higher average chromium, hafnium, lithium, and zirconium contents than its replacement, reference sample NBS-97b. The differences between the plastic clay NBS-98 and its replacement, NBS-98b, are not as pronounced. The trace element contents of the flint and plastic clays from Missouri, NBS-97a and NBS-98a, differ significantly from those of the clays from Pennsylvania, especially the average rare earth element (REE) contents. The trace element contents of clay sample IPT-32 differ from those of the other plastic clays. IPT-28 and IPT-42 have some average trace element contents that differ not only between these two samples but also from all the other clays. IPT-28 has the highest summation of the average REE contents of the 10 samples. The uranium content of NBS-98a, 46 parts per million, is very much higher than that of the other clays. Plots of average REE contents of the flint and plastic clays, normalized to chondritic abundances, show that the clays from Missouri differ from the same types of clay from Pennsylvania. The plot of REE contents for the miscellaneous clays shows that the normalized means for the elements lanthanum through samarium for IPT-28 are much greater than those for the other miscellaneous clays. The means for the elements europium through lutetium are similar for all three miscellaneous clays.

To validate clinically the nursing outcome "Swallowing status". The adjustment of the nursing outcome was investigated according to the Classical and Item Response Theories. The models were compared regarding information loss, goodness-of-fit, and differential item functioning. Stability and internal consistency were examined. The nursing outcome has the best fit in the generalized partial credit model with different discrimination parameters. Strong correlations among the scores of each indicator were observed. There was no differential item functioning of the outcome indicators. The scale presented high internal consistency (Cronbach's α = .954) and stability (and > .800). This study presents a valid nursing outcome. Most accurate monitoring of sensitivity to an intervention. Validar clinicamente o resultado de enefermagem "Estado da Deglutição". MÉTODOS: O ajustamento do resultado foi investigado de acordo com as teorias Clássica e de Resposta ao Item. Os modelos foram comparados assumindo parâmetros de itens cruzados de igual discriminação. Investigaram-se as propriedades de bondade do ajuste, funcionamento diferencial dos itens, estabilidade e consistência interna. O resultado se ajustou melhor a partir do Modelo de crédito parcial generalizado, o qual demonstrou unidimensionalidade do resultado e forte correlação entre os escores de cada indicador. Não houve funcionamento diferencial dos indicadores. A consistência interna para a escala global (Cronbach's α = .954) e a estabilidade (>.800) mantiveram-se elevadas. CONCLUSÃO: O estudo apresenta um resultado de enfermagem válido. RELEVÂNCIA PARA A PRÁTICA CLÍNICA: Maior acurácia para monitorar a sensibilidade da intervenção. © 2017 NANDA International, Inc.

Fotometria de grupos compactos de galáxias no infravermelho próximo

NASA Astrophysics Data System (ADS)

Brasileiro, F.; Mendes de Oliveira, C.

2003-08-01

Apresentamos medidas nas bandas J, H e K de cerca de 90 galáxias em 34 grupos compactos. Através da combinação dos novos dados, com dados obtidos na literatura para a banda B, investigamos como as luminosidades, cores, tamanhos e massas das galáxias em grupos compactos foram afetadas por processos dinâmicos, e como essas diferem de galáxias em ambientes menos densos. Uma comparação dos novos valores obtidos com aqueles listados no catálogo 2MASS, mostram que para 50 galáxias estudadas em comum, as diferenças nas magnitudes J, H e K estão dentro dos erros fotométricos. Através da construção dos diagramas de cor (J-H x H-K e B-H x J-K), percebemos que as galáxias em grupos compactos ocupam posições no diagrama diferentes das posições de galáxias em campo ou em aglomerados, sendo mais parecidas com as posições ocupadas por galáxias HII, ou com excesso de poeira, acreditamos que tal deslocamento é derivado do aumento da taxa de formação estelar.

2003-08-01

Propomos uma missão espacial para medir a forma e o diâmetro solar com o objetivo de ajudar a determinar o potencial gravitacional do Sol e a sua rotação com precisão, testar modelos teóricos de variação de energia e pela primeira vez medir os modos g de oscilação. As observações serão obtidas através do instrumento denominado APT (Astrometric and Photometric Telescope) descrito por Kuhn(1983). A sensibilidade do instrumento é de 0,2 mas em 27 dias para as observações do diâmetro solar feitas a cada minuto. Esta é uma missão de três anos de duração e pode complementar as medidas que serão feitas pelo satélite PICARD (a ser lançado em 2007). Outros parâmetros físicos podem ser obtidos com as mesmas imagens o que certamente interessará à comunidade de física solar. Um primeiro contato foi realizado com a agência espacial brasileira que pretende lançar um satélite científico a cada dois anos.

A correlação índice espectral vs. luminosidade em QSOs e suas implicações

NASA Astrophysics Data System (ADS)

Garcia-Rissmann, A.

2003-08-01

Estudos de variabilidade de núcleos ativos já demonstraram ser comum o fato de seu contínuo óptico/UV tornar-se mais "duro" à medida que a luminosidade aumenta. Essa tendência ocorre tanto de forma individual quanto global, e pode ter implicações importantes (1) para estudos fotométricos de variabilidade conduzidos numa banda fixa no referencial do observador, comparando objetos a diferentes redshifts, e (2) no cálculo da correção K, com consequente impacto na determinação de massas de buracos negros e bojos de galáxias hospedeiras (através da relação de Magorrian). Confirmo aqui as correlações positivas entre o índice espectral e a luminosidade óptica, utilizando dados espectroscópicos de 11 QSOs monitorados no Brasil e no Chile, durante ~2 anos. O estudo é complementado com parâmetros extraídos de espectros e de dados fotométricos públicos de quasares. Destaco ainda as diferenças observadas em tais correlações para objetos do tipo radio-loud e radio-quiet. Este projeto é financiado pelo I. Milênio/CNPq.

Cavidades reentrantes de nióbio vêm sendo utilizadas pelo grupo Australiano nos transdutores eletromecânicos paramétricos do detector de ondas gravitacionais Niobè. Esses transdutores paramétricos são ativados por um sinal AC na faixa de microondas (banda X), que é modulado pelo sinal mecânico da vibração da antena esférica, com a variação de um parâmetro, que, no caso, é a capacitância da cavidade. Nós estudamos esse tipo de cavidade, com o objetivo de transformá-la de reentrante aberta para reentrante fechada, de forma a utilizá-la nos transdutores paramétricos do detector brasileiro Mario Schenberg. O desempenho do transdutor depende de alguns parâmetros da cavidade, como a sua Figura de Mérito (Q elétrico) e o seu acoplamento elétrico com o circuito externo. Neste trabalho mostramos a medida do Q elétrico como função do acoplamento, do acabamento superficial interno e do vazamento de microondas da cavidade, e mostramos o desempenho esperado para o detector Mario Schenberg usando uma cavidade supercondutora reentrante fechada de nióbio.

2003-08-01

Estuda-se as características físicas das fontes supermoles (de raios X (SSS), utilizando dados ópticos e em altas energias, no âmbito de um trabalho de IC. Trata-se de binárias que apresentam espectro X muito mole, baixas temperaturas e altas luminosidades bolométricas. Esse sistemas são compostos por uma anã branca realizando fusão em sua superfície, a partir de matéria perdida pela estrela companheira. Os resíduos de fusão se acumulam na superfície da anã branca, e essa pode ultrapassar o limite de Chadrasekhar, produzir um colapso gravitacional, sendo esse um dos cenários propostos para as explosões de SN Ia. Apresentamos nesta comunicação o estado da arte das características físicas das fontes SSS, situando-as no âmbito das VCs. Procuramos também situar esses objetos em relação às variáveis galácticas V Sge, na medida em que os dois grupos apresentam certas caracerísticas bastante semelhantes.A metodologia adotada é aquela pedagógico-cognitiva clássica de um trabalho de IC na área de ciências exatas.

Study of hydrogen in phthalocyanine semiconductors using muSR technique =

NASA Astrophysics Data System (ADS)

Duarte, Joao Pedro Piroto Pereira

Este trabalho apresenta um estudo experimental dos semicondutores organicos Ftalocianina (H2Pc), Ftalocianina de Zinco (ZnPc) e Ftalocianina de Cobre (CuPc) por tecnicas de µSR, tendo-se obtido informacao detalhada sobre a estrutura electronica dos estados de carga formados pelo muao positivo nos tres compostos, e sobre as interaccoes dinamicas a que esses estados se encontram sujeitos. Os resultados do estudo indicam que nas ftalocianias com caracter nao magneticas H2Pc e ZnPc se da a formacao de tres radicais muonicos paramagneticos distintos. A estrutura hiperfina destes radicais, referidos como estados I, II e III, foi caracterizada atraves da medida dos parametros de acoplamento hipefino em conjunto com a parameterizacao da sua dependencia com a temperatura. Uma quarta componente paramagnetica do sinal µSR foi tambem identificada, mas sobre a qual nao foi possivel retirar conclusoes definitivas quanto a sua origem. Verificou-se que os parametros de acoplamento hiperfino isotropicos dos tres estados identificados se encontram numa regiao de valores entre os 100 e os 150MHz para os estados I e II, enquanto que para o estado III esta quantidade toma valores em torno de 10 MHz. A estrutura electronica de todos os estados possui simetria axial, caracterizada por parametros dipolares de cerca de 15MHz para os estados I e II, e 20MHz para o estado III. A origem dos estados I e II foi determinada como sendo devida a adicao de muonio a uma das ligacoes duplas existentes nos aneis benzenicos da periferia das moleculas de ftalocianina recorrendo a calculos de estrutura electronica, tendo-se verificado a existencia de um acoplamento entre a interaccao hiperfina desses estados e modos vibracionais desses aneis. A problematica da localizacao do estado III tambem foi abordada, tomando-se como hipotese mais provavel uma posicao intersticial entre duas moleculas de ftalocianina. O estudo das interaccoes dinamicas de spin destes tres estados revelou que o estado III esta sujeito a um fenomeno de spin exchange, originado pela colisao com portadores de carga presentes no material. A taxa de spin-flip relativa a esta interaccao foi deduzida a partir de medidas µSR em geometria de campo longitudinal, tendo sida determinada a barreira energetica existente para a difusao de portadores de carga entre moleculas de ftalocianina localizadas dentro da mesma estrutura colunar tanto na H2Pc, como na ZnPc. Por fim, o sinal µSR da ftalocianina com caracter magnetico CuPc foi tambem caracterizado. Foram identificadas duas componentes de caracter aparentemente diamagnetico com taxas de relaxacao separadas por cerca de duas ordens de grandeza, atribuidas a duas configuracoes distintas para o emparelhamento entre o electrao do radical muonico, e o electrao com spin desemparelhado localizado no atomo de cobre. Os dois emparelhamentos diferentes geram um ambiente puramente diamagnetico para o muao, o que origina a componente de relaxacao lenta, e uma configuracao na qual existe uma densidade de spin flutuante na posicao do muao, responsavel pela componente de relaxacao elevada.

The study of gravitation constitutes an exceptional occasion to show the richness and complexity of science and technology, contemplating, among other things: the problematic situations which are at the heart of the scientific knowledge, the difficulties encountered in the construction of knowledge and, especially, the necessity of overcoming "common-sense evidence" that proclaimed the existence of an insurmountable barrier between Earth and Heavens, hindering scientific development during many centuries. In this paper we present a program of activities to orient the study of Gravitation atUpperHigh School, favoring students' participation in the reconstruction of this first scientific revolution and giving them the opportunity to see the importance of Astronomy both in the history of science and today. El estudio de la gravitación constituye una ocasión excepcional para mostrar la ciencia y la tecnología en toda su riqueza y complejidad, considerando, entre otros aspectos:

This proceedings presents selected contributions from the participants of South America Dynamics Days 2011, which was hosted by the National Institute for Space Research (INPE), Brazil, in July 2010. Dynamics Days was founded in 1980 and is the longest standing and most respected international series of meetings devoted to the field of dynamics and nonlinearity. Traditionally it has brought together researchers from a wide range of backgrounds - including physics, biology, engineering, chemistry and mathematics - for interdisciplinary research into nonlinear science. Dynamics Days South America 2010 marked the beginning of the South American branch of Dynamics Days. It brought together, for the first time in South America, researchers from a wide range of backgrounds who share a common interest in the theory and applications of nonlinear dynamics. Thus, South American researchers had a forum to promote regional as well as international scientific and technological exchange and collaboration especially, but not exclusively, on problems that are particularly relevant for the development of science and technology in the South American region. Furthermore, the conference also brought together prominent scientists from around the world to review recent developments in nonlinear science. This conference comprised plenary invited talks, minisymposia, contributed talks and poster sessions. The articles that are compiled here were chosen from among the works that were presented as contributed talks and posters. They represent a good selection which allows one to put issues that were discussed during the conference into perspective. It is possible to evaluate the success of an initiative by using several indices. In relation to attendees, the conference had 311 participants from 22 countries, who presented 341 works. About 86% of the participants came from South American countries. These figures allow one to classify this Dynamics Days conference as that with the greatest number of attendees ever. Finally, we would like to express our gratitude to all the participants for their presentations, discussions, and remarkable interactions with one another. The tireless work undertaken by all the members of the International Advisory Committee and the Organizing Committee must also be recognized. We also wish to express our deep appreciation for the Scientific Societies and Research Support Agencies which supported the conference and provided all the resources which were necessary to make this idea of a South American Dynamics Days come true.

to psychometrically test the Brazilian version of the Treatment Satisfaction Questionnaire for Medication - TSQM (version 1.4), regarding ceiling and floor effect, practicability, acceptability, reliability and validity. participants with coronary heart disease (n=190) were recruited from an outpatient cardiology clinic at a university hospital in Southeastern Brazil and interviewed to evaluate their satisfaction with medication using the TSQM (version 1.4) and adherence using the Morisky Self-Reported Measure of Medication Adherence Scale and proportion of adherence. The Ceiling and Floor effect were analyzed considering the 15% worst and best possible TSQM scores; Practicability was assessed by time spent during TSQM interviews; Acceptability by proportion of unanswered items and participants who answered all items; Reliability through the Cronbach's alpha coefficient and Validity through the convergent construct validity between the TSQM and the adherence measures. TSQM was easily applied. Ceiling effect was found in the side effects domain and floor effect in the side effects and global satisfaction domains. Evidence of reliability was close to satisfied in all domains. The convergent construct validity was partially supported. the Brazilian TSQM presents evidence of acceptability and practicability, although its validity was weakly supported and adequate internal consistency was observed for one domain. realizar o teste psicométrico da versão brasileira do Treatment Satisfaction Questionnaire for Medication - TSQM (versão 1.4) [Questionário Satisfação com Tratamento Medicamentoso] com relação aos efeitos de teto e chão, praticidade, aceitabilidade, confiabilidade e validade. os participantes com doença cardíaca coronária (n=190) foram recrutados num ambulatório de cardiologia de um hospital universitário no sudeste do Brasil e entrevistados para avaliar satisfação em relação ao tratamento medicamentoso através da TSQM (versão 1.4) e adesão através da Morisky Self-Reported Measure of Medication Adherence Scale [Medida de Auto-Relato de Adesão ao Tratamento Medicamentoso] e proporção de aderência.

Seguridad del paciente en Radioterapia Intraoperatoria: Impacto de los elementos controlados por el Radiofisico

NASA Astrophysics Data System (ADS)

Tarjuelo, Juan Lopez

Introduccion: En la administracion de la radioterapia intervienen profesionales y equipos de tratamiento, por lo que existe el riesgo de error y se precisa que dicho equipamiento funcione conforme a lo esperado. A los radiofisicos les corresponde participar en las actividades de garantia o aseguramiento de la calidad, incluyendo el control de calidad de los equipos, y en la evaluacion de los riesgos asociados. La radioterapia intraoperatoria (RIO) es una tecnica radioterapica de intensificacion de dosis, altamente selectiva, dirigida a volumenes anatomicos restringidos durante el tratamiento quirurgico oncologico, basada en la administracion de una dosis absorbida alta por medio de un haz de electrones tras el examen visual directo del lecho tumoral. Como incorporar los ultimos avances en el refuerzo de la seguridad en radioterapia es una tarea ambiciosa y compleja, resulta mas concreta y de inmediata aplicacion su introduccion en la RIO. El objetivo es analizar los elementos que reducen los riesgos y aumentan la seguridad en la RIO y su dosimetria, y valorar la funcion del radiofisico en esta labor. Material y metodos: Se emplearon el planificador Radiance de GMV y el acelerador lineal de los tratamientos de RIO Elekta Precise, controlado con el verificador diario de haces Daily QA Check 1090 y medido con las camaras de ionizacion PPC 40, FC65-G y FC65-P de PTW-Freiburg, a su vez verificadas con fuentes radiactivas adecuadas de estroncio-90 modelos CDP y CDC de IBA Dosimetry. Se realizo un analisis de modos de fallo y efectos (failure mode and effect analysis, FMEA) con el fin de identificar los elementos que forman la RIO y aplicar las herramientas necesarias para la minimizacion de los riesgos y la mejora de la seguridad en la tecnica. Se estudiaron las verificaciones diarias de dicho acelerador Precise con el control estadistico de procesos (statistical process control, SPC) y se simularon intervenciones para devolverlo al estado llamado en control. El SPC tambien se uso para estudiar la estabilidad de las camaras de ionizacion mencionadas. Se realizo la dosimetria in vivo en 45 pacientes con MOSFET reforzados mobile TN-502RDM-H, pelicula radiocromica Gafchromic MD-55-2, y se elaboro un modelo teorico para explicar los datos. Por ultimo, al precisarse el uso en RIO de la simulacion virtual y del calculo de la dosis absorbida en el paciente virtual, se ha ilustrado este apartado con la aceptacion y el estado de referencia inicial del planificador de tratamientos modulados con calculo de Monte Carlo Elekta Monaco. Para ello se utilizaron la camara de ionizacion TW31016-0104 y la matriz seven29 de PTW-Freiburg, pelicula radiocromica Gafchromic EBT-2, y diferentes maniquies. Resultados: El FMEA identifico 57 modos de fallo y efectos potenciales. No se experimentaron sucesos relativos a una administracion inadecuada de la dosis absorbida. Se identificaron las revisiones dobles y por un par como claves para reducir los riesgos asociados al equipo de profesionales involucrado en la RIO. Se identificaron tambien oportunidades de mejora con el uso de la automatizacion y el enclavamiento. En cuanto al SPC, los indices de capacidad del proceso abarcaron de 1,6 a 9,3 para un nivel de especificaciones del +/-2%. Las intervenciones simuladas alcanzaron del 2% al 34% de las sesiones de medida. Las camaras de ionizacion Farmer derivaron en direcciones opuestas en un periodo de 6 anos; aunque ello no se aprecio en los informes de calibracion del laboratorio acreditado. No derivo la camara PPC-40. En la dosimetria in vivo, las medidas de los MOSFET no se desviaron significativamente de las medidas con pelicula. Los valores centrales de las dosis absorbidas quedaron entre la dosis absorbida prescrita y la maxima, con lo que indicaron un tratamiento correcto del lecho tumoral. Las anchuras de los intervalos de confianza de las dosis absorbidas esperadas segun el modelo teorico al nivel del 95% abarcaron del 8,6% al 14,7%. Las verificaciones de Monaco resultaron satisfactorias excepto en el caso de la transferencia de datos, que obligo a cambiar el flujo de trabajo. Conclusiones: El FMEA es crucial para priorizar las intervenciones reductoras del riesgo. Tipos diferentes de procesos fallidos se pueden eliminar o paliar con tipos diferentes de tales intervenciones. El SPC puede evaluar la variabilidad inherente del procedimiento monitorizador de haces de electrones, indica cuando intervenir para devolver un proceso al estado de control y si un proceso es capaz con respecto a unas especificaciones o requisitos establecidos. Es viable realizar dosimetria in vivo con un acelerador convencional fijo y obtener resultados satisfactorios en cada localizacion estudiada a pesar de su variabilidad. El modelo teorico desarrollado puede describir con exito resultados globales, aunque no puede explicar todos los datos experimentales. Se ha mostrado que un planificador puede funcionar correctamente en condiciones de laboratorio o trabajando solo; pero puede fallar cuando se conecta con otros equipos de radioterapia. Todos estos aspectos presentados y evaluados aqui constituyen competencias actuales o futuras, y deseables, de los radiofisicos, tanto en el campo de la RIO como en la extension a la radioterapia en su conjunto.

Depth of the base of the Jackson aquifer, based on geophysical exploration, southern Jackson Hole, Wyoming, USA

NASA Astrophysics Data System (ADS)

Nolan, Bernard T.; Campbell, David L.; Senterfit, Robert M.

A geophysical survey was conducted to determine the depth of the base of the water-table aquifer in the southern part of Jackson Hole, Wyoming, USA. Audio-magnetotellurics (AMT) measurements at 77 sites in the study area yielded electrical-resistivity logs of the subsurface, and these were used to infer lithologic changes with depth. A 100-600ohm-m geoelectric layer, designated the Jackson aquifer, was used to represent surficial saturated, unconsolidated deposits of Quaternary age. The median depth of the base of the Jackson aquifer is estimated to be 200ft (61m), based on 62 sites that had sufficient resistivity data. AMT-measured values were kriged to predict the depth to the base of the aquifer throughout the southern part of Jackson Hole. Contour maps of the kriging predictions indicate that the depth of the base of the Jackson aquifer is shallow in the central part of the study area near the East and West Gros Ventre Buttes, deeper in the west near the Teton fault system, and shallow at the southern edge of Jackson Hole. Predicted, contoured depths range from 100ft (30m) in the south, near the confluences of Spring Creek and Flat Creek with the Snake River, to 700ft (210m) in the west, near the town of Wilson, Wyoming. Résumé Une campagne géophysique a été entreprise pour préciser la profondeur du mur de l'aquifère dans le secteur sud de Jackson Hole (Wyoming, États-Unis). Des mesures audio-magnétotelluriques (audio MT) sur 77 sites de ce secteur ont fourni des logs de résistivitéélectrique du sous-sol ; les variations de la lithologie en fonction de la profondeur en ont été déduites. Un niveau géoélectrique à 100-600ohm.m, dénommé "aquifère de Jackson", a servi à définir des dépôts superficiels quaternaires saturés en eau et non consolidés. La profondeur médiane de la base de l'aquifère de Jackson est de l'ordre de 61m, à partir des 62 sites ayant fourni suffisamment de données de résistivité. Les valeurs audio MT mesurées ont été krigées afin d'estimer la profondeur de la base de la formation aquifère dans la partie sud de Jackson Hole. Les cartes d'isovaleurs d'estimation krigées indiquent que la profondeur de la base de la formation aquifère de Jackson est faible dans la partie centrale de la zone d'étude à l'est et à l'ouest des monts Gros Ventre, plus grande dans le secteur ouest près de la zone faillée de Teton, et faible sur la bordure sud de Jackson Hole. Les profondeurs estimées vont de 30m au sud, près des confluences des rivières Spring et Flat avec la rivière Snake, à 210m à l'ouest près de la ville de Wilson (Wyoming). Resumen Se llevó a cabo una campaña geofísica para determinar la profundidad del basamento de un acuífero libre en la zona sur de Jackson Hole, Wyoming, EEUU. USA. Medidas audio-magnetotelúricas (ATM) en 77 lugares de la zona de estudio dieron lugar a registros de resistividad eléctrica del subsuelo, que se usaron para inferir los cambios litológicos con la profundidad. Los depósitos superficiales, saturados y no consolidados de edad cuaternaria, el acuífero de Jackson, forman una capa de resistencia geoeléctrica entre 100-600ohm-m. La profundidad media de la base del acuífero de Jackson se estima en unos 61m (200pies), a partir de 62 registros con medidas suficientes. Los valores ATM fueron krigeados para obtener una medida de la profundidad del basamento del acuífero en la zona sur de Jackson Hole. Los mapas de isoprofundidades obtenidos por krigeado indican que el acuífero es poco profundo en la parte central de la zona de estudio, cerca de los Gros Ventre Buttes orientales y occidentales, más profundo al oeste, cerca del sistema de fallas de Teton, y menos profundo en el borde sur de Jackson Hole. Las profundidades van desde 30m (100pies) en el sur, en la confluencia entre los desfiladeros Spring y Flat con el Río Snake, hasta 210m (700pies) al oeste, cerca de la ciudad de Wilson, Wyoming.

to investigate evidence in the literature on procedures for measuring gastric tube insertion in newborns and verifying its placement, using alternative procedures to radiological examination. an integrative review of the literature carried out in the Cochrane, LILACS, CINAHL, EMBASE, MEDLINE and Scopus databases using the descriptors "Intubation, gastrointestinal" and "newborns" in original articles. seventeen publications were included and categorized as "measuring method" or "technique for verifying placement". Regarding measuring methods, the measurements of two morphological distances and the application of two formulas, one based on weight and another based on height, were found. Regarding the techniques for assessing placement, the following were found: electromagnetic tracing, diaphragm electrical activity, CO2 detection, indigo carmine solution, epigastrium auscultation, gastric secretion aspiration, color inspection, and evaluation of pH, enzymes and bilirubin. the measuring method using nose to earlobe to a point midway between the xiphoid process and the umbilicus measurement presents the best evidence. Equations based on weight and height need to be experimentally tested. The return of secretion into the tube aspiration, color assessment and secretion pH are reliable indicators to identify gastric tube placement, and are the currently indicated techniques. investigar, na literatura, evidências sobre procedimentos de mensuração da sonda gástrica em recém-nascidos e de verificação do seu posicionamento, procedimentos alternativos ao exame radiológico. revisão integrativa da literatura nas bases Biblioteca Cochrane, LILACS, CINAHL, EMBASE, MEDLINE e Scopus, utilizando os descritores "intubação gastrointestinal" e "recém-nascido" em artigos originais. dezessete publicações foram incluídas e categorizadas em "método de mensuração" ou "técnica de verificação do posicionamento". Como métodos de mensuração, foram encontrados os de tomada de duas distâncias morfológicas e os de aplicação de duas fórmulas, uma baseada no peso e outra na altura. Para técnicas de verificação do posicionamento, encontrou-se traçado eletromagnético, atividade elétrica do diafragma, detecção de CO2, solução de índigo carmim, ausculta do epigástrio, aspiração de secreção gástrica, inspeção da cor, avaliação de pH, enzimas e bilirrubina. o método de mensuração que utiliza as medidas do nariz ao lóbulo da orelha ao ponto médio entre apêndice xifoide e cicatriz umbilical apresenta melhores evidências. As equações baseadas em peso e altura necessitam ser testadas experimentalmente.

Leishmaniases are serious diseases caused by trypanosomatid protozoans of the genus Leishmania transmitted by the bite of phlebotomine sand flies. We analyzed records pertaining to Lutzomyia longipalpis (Lutz and Neiva, 1912) and Lutzomyia cruzi (Mangabeira, 1938) in Brazil from the following sources: the collection of phlebotomine sand flies of the Centro de Pesquisas René Rachou/Fiocruz (FIOCRUZ-COLFLEB), the "SpeciesLink" (CRIA) database, from systematic surveys of scientific articles and gray literature (dissertations, theses, and communications), and disease data obtained from the Information System for Notifiable Diseases/Ministry of Health (SINAN/MS). Environmental data and ecological niche modeling (ESMS) using the approach of MaxEnt algorithm produced maps of occurrence probability for both Lu. longipalpis and Lu. cruzi. Lutzomyia longipalpis was found in 229 Brazilian municipalities and Lu. cruzi in 27. The species were sympatric in 16 municipalities of the Central-West region of Brazil. Our results show that Lu. longipalpis is widely distributed and associated with the high number of cases of visceral leishmaniasis reported in Brazil. © The Authors 2017.

In this work, a new extended-length parallel-plate ionization chamber was tested in the standard radiation qualities for computed tomography established according to the half-value layers defined at the IEC 61267 standard, at the Calibration Laboratory of the Instituto de Pesquisas Energéticas e Nucleares (IPEN). The experimental characterization was made following the IEC 61674 standard recommendations. The experimental results obtained with the ionization chamber studied in this work were compared to those obtained with a commercial pencil ionization chamber, showing a good agreement. With the use of the PENELOPE Monte Carlo code, simulations were undertaken to evaluate the influence of the cables, insulator, PMMA body, collecting electrode, guard ring, screws, as well as different materials and geometrical arrangements, on the energy deposited on the ionization chamber sensitive volume. The maximum influence observed was 13.3% for the collecting electrode, and regarding the use of different materials and design, the substitutions showed that the original project presented the most suitable configuration. The experimental and simulated results obtained in this work show that this ionization chamber has appropriate characteristics to be used at calibration laboratories, for dosimetry in standard computed tomography and diagnostic radiology quality beams.

Ondas Alfvén em plasma astrofísico têm sido objeto de intenso estudo nas últimas décadas pelo fato de apresentarem papel importante em muitas áreas de pesquisa na astrofísica. Particularmente são importantes no mecanismo de aquecimento da coroa solar; em ventos estelares; em jatos galácticos e extragalácticos; em discos protoestelares, etc. A formulação para diferenças finitas no domínio do tempo (FDTD), aplicada a plasma magnetizado é desenvolvida para estudo das propriedades de ondas Alfvén em três dimensões (3D-FDTD). O método é aplicado inicialmente a um plasma homogêneo e isotérmico imerso em uma região com campo magnético externo B0, que sofre uma pequena perturbação. Uma vez gerada a onda, esta perturbação é retirada e, então analisamos a evolução temporal das ondas, bem como a forma de seu amortecimento.

Neste artigo discutimos a visão da Igreja Católica sobre sexualidade na interface com a epidemia do HIV/AIDS. Nossa reflexão está embasada em pesquisa etnográfica que envolveu dois meses de observação participante do cotidiano de católicos de um bairro popular da Região Metropolitana do Recife, além de contar com entrevistas a onze dos leigos engajados nos serviços religiosos da igreja do bairro e a oito sacerdotes que realizam seus trabalhos religiosos em outras localidades. Nelas abordamos diferentes temáticas relacionadas ao enfrentamento da epidemia da AIDS. Nesse contexto, conjugalidade e fidelidade se afiguram como importantes analisadores de como aqueles lidam com a epidemia, em uma variedade de re-descrições práticas e de re-interpretações conceptuais das assertivas do discurso moral religioso – ainda que, muitos impasses permaneçam em aberto em termos das prerrogativas da Igreja e seus possíveis rebatimentos na saúde sexual dos adeptos.

We report a novel mechanical response of few-layer graphene, h-BN, and MoS2 to the simultaneous compression and shear by an atomic force microscope (AFM) tip. The response is characterized by the vertical expansion of these two-dimensional (2D) layered materials upon compression. Such effect is proportional to the applied load, leading to vertical strain values (opposite to the applied force) of up to 150%. The effect is null in the absence of shear, increases with tip velocity, and is anisotropic. It also has similar magnitudes in these solid lubricant materials (few-layer graphene, h-BN, and MoS2), but it is absent in single-layer graphene and in few-layer mica and Bi2Se3. We propose a physical mechanism for the effect where the combined compressive and shear stresses from the tip induce dynamical wrinkling on the upper material layers, leading to the observed flake thickening. The new effect (and, therefore, the proposed wrinkling) is reversible in the three materials where it is observed.[2] Financial support from CNPq, Fapemig, Rede Nacional de Pesquisa em Nanotubos de Carbono and INCT-Nano-Carbono

In several countries, there has been an increase in the use of radiation for food processing thus improving the quality and sanitary conditions, inhibiting pathogenic microorganisms, delaying the natural aging process and so extending product lifetime. The need to develop analytical methods to detect these irradiated products is also increasing. The goal of this research was to identify wheat irradiated using different radiation doses. Seeds were irradiated with a gamma 60Co source (Gammacell 220 GC) in the Centro de Energia Nuclear na Agricultura and the Instituto de Pesquisas Energéticas e Nucleares. Dose rate used were 1.6 and 5.8kGy/h. Applied doses were 0.0, 0.10, 0.25, 0.50, 0.75, 1.0, and 2.0kGy. After irradiation, seeds were analysed over a 6 month period. Three different detection methods were employed to determine how irradiation had modified the samples. Screening methods consisted of a germination test measuring the inhibition of shooting and rooting and analysis of DNA fragmentation. The method of electron spin resonance spectroscopy allowed a better dosimetric evaluation. These techniques make the identification of irradiated wheat with different doses possible.

In the last decade, evidence regarding chronic pain has developed exponentially. Numerous studies show that many chronic pain populations show specific neuroplastic changes in the peripheral and central nervous system. These changes are reflected in clinical manifestations, like a generalized hypersensitivity of the somatosensory system. Besides a hypersensitivity of bottom-up nociceptive transmission, there is also evidence for top-down facilitation of pain due to malfunctioning of the endogenous descending nociceptive modulatory systems. These and other aspects of modern pain neuroscience are starting to be applied within daily clinical practice. However, currently the application of this knowledge is mostly limited to the general adult population with musculoskeletal problems, while evidence is getting stronger that also in other chronic pain populations these neuroplastic processes may contribute to the occurrence and persistence of the pain problem. Therefore, this masterclass article aims at giving an overview of the current modern pain neuroscience knowledge and its potential application in post-cancer, paediatric and sports-related pain problems.

Jatropha is a potential oilseed crop, which requires mitigating factors such as the low genetic variability of the species. The solution runs through the research of Brazilian germplasm. Attention should be given to the germplasm of jatropha the north of Minas Gerais, because this is the oldest national collection and because this region may be a regions of jatropha diversity due to selection pressure arising from environmental adversities. Therefore, the objective of this study was to investigate the genetic diversity of 48 accessions of collection from Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG), using SSR and ISSR markers. The results showed low genetic diversity, but some individuals stood out as J. mollissima (48), J. podagrica (47), Mexican accessions (42, 43, 44 and 45) and some national accessions (28, 29, 41 and 46). Therefore, aiming to increase the genetic variability and improve the effectiveness of jatropha breeding programs, it is suggested to explore such as parental accessions to generate commercial hybrids. This fact implies the possibility to support future production of jatropha, since this culture may be an important source of income, especially for small farmers living in semiarid regions of Brazil.

There are many discussions about the relevance of the topics covered in classes. One subject in particular is the focus of this essay: astronomy. In what sense and to what extent it would be worth to teach it in science or other kind of classes? In this paper we discuss some aspects of the advantages of dealing with this area of knowledge in schools, taking into account the epistemological and axiological dimensions of astronomy, in light of the vision of science as an intelligent dialogue with the world (Bachelard), in addition to the "problematization" knowledge of Paulo Freire. We propose that in fact the Astronomy does not need to be seen as just a new set of contents to be taught, but appears as a set of motivational contents for historical-philosophical discussions, and permit the discussion of concepts of other disciplines. Numerosas discusiones se están llevando a cabo acerca de la pertinencia de los temas tradicionalmente tratados en las clases. Uno de los temas, en particular, es el foco de este ensayo: la astronomía. ¿En qué sentido y en qué medida sería conveniente tratarla en clase, ya sea en clases de ciencias naturales, específicamente en las de astronomía o asignaturas afines? Elaboramos en este artículo algunos aspectos de las ventajas de tratar esta área del conocimiento en las escuelas, teniendo en cuenta las dimensiones epistemológica y axiológica de la astronomía, a la luz de la visión de la ciencia como un diálogo inteligente con el mundo (Bachelard), además de la propuesta del conocimiento "problematizador" de Paulo Freire. Proponemos que en realidad la astronomía no tiene por qué ser vista sólo como un nuevo conjunto de contenidos que se enseñan, sino que aparece como un conjunto de temas de motivación para el debate histórico-filosófico y para permitir la discusión de los conceptos típicos de otras disciplinas. Muitas discussões vêm acontecendo sobre a relevância dos temas abordados em sala de aula. Um tema, em particular, é foco deste ensaio: a astronomia. Em que sentido e em que medida valeria a pena abordá-la em aulas, seja de ciências, seja de astronomia especificamente, ou em disciplinas afins? Discutimos neste texto alguns aspectos das vantagens de se tratar essa área do conhecimento nas escolas, levando em conta as dimensões epistemológica e axiológica da astronomia, à luz da visão da ciência como um diálogo inteligente com o mundo, de Bachelard, além da proposta de problematização do conhecimento, de Paulo Freire. Proporemos que de fato a astronomia não precisa ser vista como apenas um novo conjunto de conteúdos a serem ensinados, mas figura como conjunto de temas motivadores para discussões histórico-filosóficas, além de permitir a abordagem de conceitos típicos de outras disciplinas.

To evaluate the vital capacity after two chest therapy techniques in patients undergoing abdominal surgical. A prospective randomized study carried out with patients admitted to the Intensive Care Unit after abdominal surgery. We checked vital capacity, muscular strength using the Medical Research Council scale, and functionality with the Functional Independence Measure the first time the patient was breathing spontaneously (D1), and also upon discharge from the Intensive Care Unit (Ddis). Between D1 and Ddis, respiratory therapy was carried out according to the randomized group. We included 38 patients, 20 randomized to Positive Intermittent Pressure Group and 18 to Volumetric Incentive Spirometer Group. There was no significant gain related to vital capacity of D1 and Ddis of Positive Intermittent Pressure Group (mean 1,410mL±547.2 versus 1,809mL±692.3; p=0.979), as in the Volumetric Incentive Spirometer Group (1,408.3mL±419.1 versus 1,838.8mL±621.3; p=0.889). We observed a significant improvement in vital capacity in D1 (p<0.001) and Ddis (p<0.001) and in the Functional Independence Measure (p<0.001) after respiratory therapy. The vital capacity improvement was not associated with gain of muscle strength. Chest therapy, with positive pressure and volumetric incentive spirometer, was effective in improving vital capacity of patients submitted to abdominal surgery. Avaliar a capacidade vital comparando duas técnicas de fisioterapia respiratória em pacientes submetidos à cirurgia abdominal. Estudo prospectivo e randomizado realizado com pacientes admitidos em Unidade de Terapia Intensiva após cirurgia abdominal. Verificamos a capacidade vital, a força muscular por meio da escala do Medical Research Council e funcionalidade pela Medida de Independência Funcional no primeiro momento em que o paciente encontrava-se em respiração espontânea (D1) e na alta da Unidade de Terapia Intensiva (Dalta). Entre D1 e Dalta, foi realizada a fisioterapia respiratória, conforme o grupo randomizado. Foram incluídos 38 pacientes, sendo 20 randomizados para Grupo Pressão Positiva Intermitente e 18 para o Grupo Incentivador Inspiratório a Volume. A capacidade vital entre o D1 e Dalta do Grupo Pressão Positiva Intermitente não teve ganho significativo (média de 1.410mL±547,2 versus 1.809mL±692,3; p=0,979), assim como no Grupo Incentivador Inspiratório a Volume (1.408,3mL±419,1 versus 1.838,8mL±621,3; p=0,889). Houve melhora significativa da capacidade vital no D1 (p<0,001) e na Dalta (p<0,001) e da Medida de Independência Funcional (p<0,001) após a fisioterapia respiratória. A melhora da capacidade vital não apresentou relação com o ganho da força muscular. A fisioterapia respiratória, por meio de pressão positiva ou de incentivador inspiratório a volume, foi eficaz na melhora da capacidade vital em pacientes submetidos à cirurgia abdominal.

The apparent motion of the Sun on the celestial sphere and the behavior of the shadows of objects over time are observable phenomena in everyday life. However, students often do not have a proper understanding of such occurrences, and can even display misconceptions about them. Therefore, we performed a research in order to know students' notions about these subjects and to evaluate the contribution to their understanding brought about by an activity performed with an interactive sundial in an informal learning environment. We investigated the ideas of 43 students from the seventh grade of middle school by applying a test with open questions before and after an activity with an analemmatic sundial, conducted by a monitor. A significant proportion of students were initially unaware of most of the phenomena treated. The intervention performed helped the students to assimilate new concepts, providing the contact with new phenomena and to a lesser degree, the development of explanations about them, indicating an educational potential of this action. However, the contribution to the understanding of some of the ideas explored was small, pointing to the need to make additional observations, studies and discussions. O movimento aparente do Sol na esfera celeste e o comportamento das sombras dos objetos com o passar do tempo são fenômenos observáveis no dia a dia. No entanto, muitas vezes os estudantes não possuem uma compreensão adequada de tais ocorrências, podendo inclusive exibir concepções alternativas a seu respeito. Por isso, efetuou-se uma pesquisa com o intuito de conhecer as noções dos alunos sobre esses temas e avaliar a contribuição para seu entendimento propiciada por uma atividade feita com um relógio de Sol interativo, em um ambiente de ensino informal. Foram investigadas as ideias de 43 alunos do sétimo ano do Ensino Fundamental mediante a aplicação de um teste com questões abertas antes e depois de uma atividade com um relógio de Sol analemático, conduzida por um monitor. Uma proporção significativa de estudantes desconhecia inicialmente a maioria dos fenômenos tratados. A intervenção realizada colaborou para uma parte dos alunos assimilar novos conceitos, propiciando o contato com novos fenômenos e, em menor grau, a elaboração de explicações a respeito destes, indicando um potencial educativo dessa ação. Porém, a contribuição para o entendimento de algumas das ideias exploradas foi pequena, apontando para a necessidade de se fazer observações, estudos e discussões complementares. El movimiento aparente del Sol en la esfera celeste y el comportamiento de las sombras de los objetos a lo largo del tiempo son fenómenos observables en la vida cotidiana. Sin embargo, los estudiantes a menudo no tienen una adecuada comprensión de dichos problemas, e incluso pueden mostrar conceptos erróneos acerca de ellos. Por lo tanto, se realizó una investigación a fin de conocer las nociones de los estudiantes acerca de estas cuestiones y evaluar la contribución a su comprensión proporcionada por una actividad realizada con un reloj de Sol interactivo, en un entorno informal de aprendizaje. Se investigaron las ideas de 43 estudiantes del séptimo grado del ciclo primario mediante la aplicación de un test con preguntas abiertas antes y después de una actividad con un reloj de Sol analemático, dirigida por un monitor. Una proporción significativa de los estudiantes inicialmente desconocía la mayoría de los fenómenos tratados. La intervención realizada contribuyó para que los estudiantes asimilasen nuevos conceptos, proporcionando el contacto con nuevos fenómenos y, en menor medida, desarrollasen explicaciones acerca de estos, lo que indica un potencial educativo de esta acción. Sin embargo, la contribución a la comprensión de algunas de las ideas exploradas fue pequeña, lo que apunta a la necesidad de hacer observaciones, estudios y debates adicionales.

The shallow-to-deep convective transition over land typically refers to the growth of the convective boundary layer after sunrise, followed by the development of cumulus congestus clouds in the late morning/early afternoon and transitioning to deep convective clouds in the late afternoon and early evening. Under favorable conditions, this diurnal convection can result in organized mesoscale convective systems (MCSs) that last through the following morning. While many studies have focused on improving this process in models, the shallow-to-deep transition remains poorly represented especially over land. The recent DOE ARM mobile facility deployment in the Amazon, launched as part of GOAmazon, along with a dense GNSS network supported by Universidade do Estado do Amazonas (UEA)/Instituto Nacional de Pesquisas Espaciais (INPE) and co-located with the CHUVA Project sites for GOAmazon, are used here to examine land-based convective processes in the tropics. In particular, this aspect of a larger study of the shallow-to-deep transition explores the role of large-scale intraseasonal wave activity in supporting the growth of MCSs over the GoAmazon region. These results will be placed in the context of local forcing mechanisms for convective growth over the region in ongoing work.

Statistical analysis plans increase the transparency of decisions made in the analysis of clinical trial results. The purpose of this paper is to detail the planned analyses for the PREVENT trial, a randomized, placebo-controlled trial of patient education for acute low back pain. We report the pre-specified principles, methods, and procedures to be adhered to in the main analysis of the PREVENT trial data. The primary outcome analysis will be based on Mixed Models for Repeated Measures (MMRM), which can test treatment effects at specific time points, and the assumptions of this analysis are outlined. We also outline the treatment of secondary outcomes and planned sensitivity analyses. We provide decisions regarding the treatment of missing data, handling of descriptive and process measure data, and blinded review procedures. Making public the pre-specified statistical analysis plan for the PREVENT trial minimizes the potential for bias in the analysis of trial data, and in the interpretation and reporting of trial results.

Resumo Os aneurismas de artéria poplítea correspondem a 70% dos aneurismas periféricos e o tratamento é cirúrgico, com controvérsias sobre os resultados da via endovascular. Este estudo objetivou realizar uma revisão da literatura sobre a comparação entre cirurgia aberta e endovascular no tratamento dos aneurismas da artéria poplítea. A pesquisa foi realizada utilizando os termos apropriados nos portais de periódicos LILACS e MEDLINE, com a seleção de 15 artigos. Um total de 5.166 procedimentos cirúrgicos foram comparados, sendo 3.930 cirurgias abertas e 1.236 cirurgias endovasculares. A cirurgia aberta com bypass venoso continua sendo o padrão-ouro. A cirurgia endovascular apresenta menor tempo de internação e é uma opção viável em pacientes eletivos, com baixa expectativa de vida, alto risco cirúrgico, comorbidades e mais idosos, desde que tenham anatomia favorável para o procedimento. Contudo, são necessários estudos de longo prazo para estabelecer os reais benefícios e indicações das duas técnicas, como o ensaio clínico randomizado controlado.

Diagnosis and treatment of movement system impairment syndromes.

PubMed

Sahrmann, Shirley; Azevedo, Daniel C; Dillen, Linda Van

Diagnoses and treatments based on movement system impairment syndromes were developed to guide physical therapy treatment. This masterclass aims to describe the concepts on that are the basis of the syndromes and treatment and to provide the current research on movement system impairment syndromes. The conceptual basis of the movement system impairment syndromes is that sustained alignment in a non-ideal position and repeated movements in a specific direction are thought to be associated with several musculoskeletal conditions. Classification into movement system impairment syndromes and treatment has been described for all body regions. The classification involves interpreting data from standardized tests of alignments and movements. Treatment is based on correcting the impaired alignment and movement patterns as well as correcting the tissue adaptations associated with the impaired alignment and movement patterns. The reliability and validity of movement system impairment syndromes have been partially tested. Although several case reports involving treatment using the movement system impairment syndromes concept have been published, efficacy of treatment based on movement system impairment syndromes has not been tested in randomized controlled trials, except in people with chronic low back pain.

BACKGROUND Cutaneous leishmaniasis (CL) is endemic in the state of Paraná, Brazil. OBJECTIVE This study aimed at analysing the influence of the remaining native vegetation on the prevalence of CL in Paraná. METHODS Global testing was used for spatial autocorrelation along with simultaneous autoregressive model (SAR). The regression was based on the CL coefficient (cases/100,000 inhabitants) as a function of the percentage of natural vegetation cover, altitude, total number of cases, and spatial density (SD) per km2; the location data of the Paraná state municipalities and the detection coefficient (DC) (cases/100,000 inhabitants) of autochthonous cases of CL were obtained from the SINAN in 2012 and 2016. Data on the remaining forests were collected from the Fundação SOS Mata Atlântica and Instituto Nacional de Pesquisas Espaciais. FINDINGS The spatial regression of DC revealed statistical significance for SD (Z = 24.1359, p < 0.05, 2012-2013; Z = 24.0817, p < 0.05, 2013-2014; Z = 33.4824, p < 0.05, 2014-2015; and Z = 27.1515, p < 0.05, 2015-2016. CONCLUSIONS CL cases are reported in areas with native vegetation, such as in riparian forests. However, vegetation is not the only variable that influences the incidence of CL. PMID:29768531

Anomalous response of supported few-layer hexagonal boron nitride to DC electric fields: a confined water effect?

NASA Astrophysics Data System (ADS)

Hexagonal boron nitride (h-BN) is a two-dimensional compound from III-V family, with the atoms of boron and nitrogen arranged in a honeycomb lattice, similar to graphene. Unlike graphene though, h-BN is an insulator material, with a gap larger than 5 eV. Here, we use Electric Force Microscopy (EFM) to study the electrical response of mono and few-layers of h-BN to an electric field applied by the EFM tip. Our results show an anomalous behavior in the dielectric response for h-BN for different bias orientation: for a positive bias applied to the tip, h-BN layers respond with a larger dielectric constant than the dielectric constant of the silicon dioxide substrate; while for a negative bias, the h-BN dielectric constant is smaller than the dielectric constant of the substrate. Based on first-principles calculations, we showed that this anomalous response may be interpreted as a macroscopic consequence of confinement of a thin water layer between h-BN and substrate. These results were confirmed by sample annealing and also also by a comparative analysis with h-BN on a non-polar substrate.

We have assembled datasets to strengthen the LargeScale Biosphere Atmosphere Experiment in Amazonia (LBA). These datasets can now be accessed through the Woods Hole Research Center homepage (www.whrc.org), and will soon be linked to the Pre-LBA homepages of the Brazilian Space Research Institute's Center for Weather and Climate Prediction (Instituto de Pesquisas Espaciais, Centro de Previsao de Tempo e Estudos Climaticos, INPE/CPTEC) and through the Oak Ridge National Laboratory, Distributed Active Archive Center (ORNL/DMC). Some of the datasets that we are making available involved new field research and/or the digitization of data available in Brazilian government agencies. For example, during the grant period we conducted interviews at 1,100 sawmills across Amazonia to determine their production of sawn timber, and their harvest intensities. These data provide the basis for the first quantitative assessment of the area of forest affected each year by selective logging (Nepstad et al, submitted to Nature). We digitized the locations of all of the rural households in the State of Para that have been mapped by the Brazilian malaria combat agency (SUCAM). We also mapped and digitized areas of deforestation in the state of Tocantins, which is comprised largely of savanna (cerrado), an ecosystem that has been routinely excluded from deforestation mapping exercises.

To analyze the use of nursing terminology as an instrument of the nursing work process in Collective Health. Exploratory case study. For data collection was conducted a group interview with 24 nurses working in health units of a municipality in south central Paraná, Brazil. Data were analyzed in the light of interdependence between the structural, particular and singular dimensions contained in the Theory of Nursing Praxis Intervention in Collective Health. The situations interfering with improper use were the lack of knowledge about the origin and purpose of terminology, lack of training, and non-mandatory use. Although the nursing terminology is used as an instrument in the nursing work process in collective health, it requires training to be recognized as a classification system. At the same time, institutional policies should be employed to ensure the effective use of these instruments. Analisar a utilização de terminologia de enfermagem como instrumento do processo de trabalho do enfermeiro em Saúde Coletiva. Estudo de caso exploratório. Para coleta de dados foi realizada entrevista em grupo com 24 enfermeiros que atuam nas unidades de saúde de um município no centro-sul do Paraná, Brasil. Os dados foram analisados à luz da interdependência entre as dimensões estrutural, particular e singular contidas na Teoria da Intervenção Práxica de Enfermagem em Saúde Coletiva. As situações que interferiram na utilização inadequada foram o desconhecimento sobre origem e finalidade da terminologia, a falta de treinamento e a não obrigatoriedade de uso. A terminologia de enfermagem, apesar de utilizada como instrumento no processo de trabalho de enfermeiros em Saúde Coletiva, necessita de capacitação para ser reconhecida como sistema classificatório. Ao mesmo tempo, políticas institucionais devem ser empregadas no intuito de garantir a efetiva utilização destes instrumentos.

To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. By using data from the Health section of 2008's Pesquisa Nacional por Amostra de Domicílio (Brazil's National Household Sample Survey), we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making. Apresentar estimativas nacionais sobre o deslocamento a pé ou de bicicleta no trajeto casa-trabalho no Brasil e em 10 de suas regiões metropolitanas. Utilizando dados do Suplemento sobre Saúde da Pesquisa Nacional por Amostra de Domicílios de 2008, estimamos a frequência de pessoas empregadas que se deslocam a pé ou de bicicleta no trajeto casa-trabalho estratificada por sexo, e segundo faixa etária, escolaridade, renda domiciliar per capita, residência em área urbana ou rural, regiões metropolitanas e macrorregiões do país. Adicionalmente, estimamos a distribuição da mesma frequência segundo quintos da distribuição da renda domiciliar per capita em cada região metropolitana. Um terço dos homens e mulheres empregados desloca-se a pé ou de bicicleta de casa para o trabalho no Brasil. Em ambos os sexos, esta proporção diminui com o aumento da renda e da escolaridade e é maior entre os mais jovens, entre os que residem em área rural e naqueles residentes na região Nordeste. A depender da região metropolitana, a prática de deslocamento ativo entre os mais pobres é de duas a cinco vezes maior do que entre os mais ricos. O deslocamento a pé ou de bicicleta para o trabalho no Brasil é mais frequente entre os mais pobres e entre pessoas que vivem em áreas e regiões economicamente menos desenvolvidas. A avaliação do deslocamento ativo no País traz informações importantes para a discussão de políticas públicas de mobilidade.

Malaria was eliminated from southern and southeastern Brazil over 50 years ago. However, an increasing number of autochthonous episodes attributed to Plasmodium vivax have recently been reported from the Atlantic Forest region of Rio de Janeiro state. As the P vivax-like non-human primate malaria parasite species Plasmodium simium is locally enzootic, we performed a molecular epidemiological investigation to determine whether zoonotic malaria transmission is occurring. We examined blood samples from patients presenting with signs or symptoms suggestive of malaria as well as from local howler monkeys by microscopy and PCR. Samples were included from individuals if they had a history of travel to or resided in areas within the Rio de Janeiro Atlantic Forest, but not if they had malaria prophylaxis, blood transfusion or tissue or organ transplantation, or had travelled to known malaria endemic areas in the preceding year. Additionally, we developed a molecular assay based on sequencing of the parasite mitochondrial genome to distinguish between P vivax and P simium, and applied this assay to 33 cases from outbreaks that occurred in 2015, and 2016. A total of 49 autochthonous malaria cases were reported in 2015-16. Most patients were male, with a mean age of 44 years (SD 14·6), and 82% lived in urban areas of Rio de Janeiro state and had visited the Atlantic Forest for leisure or work-related activities. 33 cases were used for mitochondrial DNA sequencing. The assay was successfully performed for 28 samples, and all were shown to be P simium, indicative of zoonotic transmission of this species to human beings in this region. Sequencing of the whole mitochondrial genome of three of these cases showed that P simium is most closely related to P vivax parasites from South America. The malaria outbreaks in this region were caused by P simium, previously considered to be a monkey-specific malaria parasite, related to but distinct from P vivax, and which has never conclusively been shown to infect people before. This unequivocal demonstration of zoonotic transmission, 50 years after the only previous report of P simium in people, leads to the possibility that this parasite has always infected people in this region, but that it has been consistently misdiagnosed as P vivax because of an absence of molecular typing techniques. Thorough screening of local non-human primates and mosquitoes (Anopheline) is required to evaluate the extent of this newly recognised zoonotic threat to public health and malaria elimination in Brazil.

Ionospheric weather maps using the total electron content (TEC) monitored by ground-based Global Navigation Satellite Systems (GNSS) receivers over South American continent, TECMAP, have been operationally produced by Instituto Nacional de Pesquisas Espaciais's Space Weather Study and Monitoring Program (Estudo e Monitoramento Brasileiro de Clima Especial) since 2013. In order to cover the whole continent, four GNSS receiver networks, (Rede Brasileiro de Monitoramento Contínuo) RBMC/Brazilian Institute for Geography and Statistics, Low-latitude Ionospheric Sensor Network, International GNSS Service, and Red Argentina de Monitoreo Satelital Continuo, in total 140 sites, have been used. TECMAPs with a time resolution of 10 min are produced in 12 h time delay. Spatial resolution of the map is rather low, varying between 50 and 500 km depending on the density of the observation points. Large day-to-day variabilities of the equatorial ionization anomaly have been observed. Spatial gradient of TEC from the anomaly trough (total electron content unit, 1 TECU = 1016 el m-2 (TECU) <10) to the crest region (TECU > 80) causes a large ionospheric range delay in the GNSS positioning system. Ionospheric plasma bubbles, their seeding and development, could be monitored. This plasma density (spatial and temporal) variability causes not only the GNSS-based positioning error but also radio wave scintillations. Monitoring of these phenomena by TEC mapping becomes an important issue for space weather concern for high-technology positioning system and telecommunication.

The COMET Program has recently published a new online module entitled "Climate Change: Fitting the Pieces Together." The module, sponsored by the National Environmental and Education Foundation (NEEF), gives a broad overview of the topic of climate change, including how scientists study climate change, observations of current changes, and projections of future impacts, as well as some thoughts on what can be done to minimize the effects. In addition, the module provides links to graphical resources, references, frequently asked questions, and a Powerpoint presentation that teachers, broadcast meteorologists, and others can adapt for their own use. The module presents the information in an engaging fashion, making full use of multimedia through audio, graphics, animations, and interactive features. COMET is also developing another module on a related topic for NEEF and the Instituto de Pesquisa Ambiental da Amazônia, an environmental organization in Brazil. In addition to providing the basics of climate change science, this course will focus on the interconnections between tropical forests, such as the Amazon, and climate change. The module also addresses international agreements to reduce climate change, with a highlight on the UN-REDD (United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries) program. The module, which should be published in late 2009 or early 2010, will have versions in English and Portuguese and possibly Spanish.

Functional disability in patients with low back pain: the mediator role of suffering and beliefs about pain control in patients receiving physical and chiropractic treatment.

PubMed

Pereira, M Graça; Roios, Edite; Pereira, Marta

Low back pain is the leading cause of disability worldwide. There is evidence that depression, anxiety, and external locus of control are negative predictors of functional disability in low back patients. This study focused on the mediator role of suffering and beliefs about pain control in the relationship between psychological morbidity and functional disability in patients receiving physical therapy and chiropractic treatment for chronic low back pain. The sample included 213 patients receiving chiropractic treatment and 125 receiving physical therapy, who answered the following instruments: Beliefs about Pain Control Questionnaire; Inventory of Subjective Experiences of Suffering in Illness; Oswestry Low Back Pain Disability Questionnaire; and the Hospital Anxiety and Depression Scales. Suffering was a mediator in the relationship between depression and functional disability in both treatment groups. Only beliefs related to external chance events mediated the relationship between depression and functional disability in the physical therapy group, but not in the chiropratic teratment group. Intervention should focus on suffering regardless of the type of treatment and target beliefs about pain control, in patients receiving physical therapy treatment since they seem to play a key role in functional disability in patients with low back pain.

ABSTRACT OBJECTIVE To quantify the household expenditure per capita and to estimate the percentage of Brazilian households that have spent with dental insurance. METHODS We analyzed data from 55,970 households that participated in the research Pesquisa de Orçamentos Familiares in 2008–2009. We have analyzed the annual household expenditure per capita with dental insurance (business and private) according to the Brazilian states and the socioeconomic and demographic characteristics of the households (sex, age, race, and educational level of the head of the household, family income, and presence of an older adult in the household). RESULTS Only 2.5% of Brazilian households have reported spending on dental insurance. The amount spent per capita amounted to R$5.10 on average, most of which consisted of private dental insurance (R$4.70). Among the characteristics of the household, higher educational level and income were associated with higher spending. São Paulo was the state with the highest household expenditure per capita (R$10.90) and with the highest prevalence of households with expenditures (4.6%), while Amazonas and Tocantins had the lowest values, in which both spent less than R$1.00 and had a prevalence of less than 0.1% of households, respectively. CONCLUSIONS Only a small portion of the Brazilian households has dental insurance expenditure. The market for supplementary dentistry in oral health care covers a restricted portion of the Brazilian population. PMID:29489995

ABSTRACT The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos –Serviços (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services) aimed to characterize the organization of pharmaceutical services in the Primary Health Care of the Brazilian Unified Health System (SUS). PNAUM – Services is a cross-sectional and evaluative study, with planned sample of 600 cities, held between 2014 and 2015, composed of a remote phase, with telephone interviews with health managers. Of these 600 cities, 300 were selected for a survey on health services. We selected the 27 capitals, the 0.5% largest cities of each region, and the remaining cities were drawn. The estimate of the representative national sample size considered three levels: cities, medicine dispensing services, and patients. The interviews were carried out with a structured questionnaire specific for: municipal secretaries of health, professionals responsible for pharmaceutical services in the city, professionals responsible for the dispensing of medicines, physicians, and patients. The secondary data were obtained in official databases, in the latest update date. PNAUM – Services was the first nationwide research aimed at the assessment and acquisition of national and regional indicators on access to medicines, as well as use and rational use, from the perspective of various social subjects.

Study of the anticorrelations between ozone and UV-B radiation using linear and exponential fits in Southern Brazil

NASA Astrophysics Data System (ADS)

Guarnieri, R.; Padilha, L.; Guarnieri, F.; Echer, E.; Makita, K.; Pinheiro, D.; Schuch, A.; Boeira, L.; Schuch, N.

Ultraviolet radiation type B (UV-B 280-315nm) is well known by its damage to life on Earth, including the possibility of causing skin cancer in humans. However, the atmo- spheric ozone has absorption bands in this spectral radiation, reducing its incidence on Earth's surface. Therefore, the ozone amount is one of the parameters, besides clouds, aerosols, solar zenith angles, altitude, albedo, that determine the UV-B radia- tion intensity reaching the Earth's surface. The total ozone column, in Dobson Units, determined by TOMS spectrometer on board of a NASA satellite, and UV-B radiation measurements obtained by a UV-B radiometer model MS-210W (Eko Instruments) were correlated. The measurements were obtained at the Observatório Espacial do Sul - Instituto Nacional de Pesquisas Espaciais (OES/CRSPE/INPE-MCT) coordinates: Lat. 29.44oS, Long. 53.82oW. The correlations were made using UV-B measurements in fixed solar zenith angles and only days with clear sky were selected in a period from July 1999 to December 2001. Moreover, the mathematic behavior of correlation in dif- ferent angles was observed, and correlation coefficients were determined by linear and first order exponential fits. In both fits, high correlation coefficients values were ob- tained, and the difference between linear and exponential fit can be considered small.

Coffea canephora genotypes from the breeding program of Instituto Capixaba de Pesquisa e Extensão Rural were evaluated, and genetic diversity was estimated with the aim of future improvement strategies. From an initial group of 55 genotypes, 18 from the region of Castelo, ES, were selected, and three clones of the cultivars "Vitória" and "robusta tropical." Upon completion of the scheduled cycle pruning, 17 morphoagronomic traits were measured in the 22 genotypes selected. The principal components method was used to evaluate the contributions relative to the traits. The genetic dissimilarity matrix was obtained through Mahalanobis generalized distance, and genotypes were grouped using the hierarchical method based on the mean of the distances. The most promising clones of Avaliação Castelo were AC02, AC03, AC12, AC13, AC22, AC24, AC26, AC27, AC28, AC29, AC30, AC35, AC36, AC37, AC39, AC40, AC43, and AC46. These methods detected high genetic variability, grouping, by similarity, the genotypes in five groups. The trait that contributed the least to genetic divergence was the number of leaves in plagiotropic branches; however, this was not eliminated, because discarding it altered the groups. There are superior genotypes with potential for use in the next stages of the breeding program, aimed at both the composition of clonal variety and hybridizations.

Throughout 2009, 5 sampling campaings were carried out at CEPEMA (Centro de Capacitação e Pesquisa em Meio Ambiente da Universidade de São Paulo), in the vicinity of PETROBRAS oil refinery. Mini-vol portable air sampler was deployed to collect coarse and fine particles. Size-fractionated particle samples were collected by a Micro-Orifice Uniform Deposition Impactor (MOUDI) device. Gravimetric analysis showed three peaks for mass size distributions: the After-Filter stage (cut point diameter of less than 0,1μm), stage 7A (d=0,32μm) and stage 3A (d= 3,2μm). Fine particle matter (FPM) concentrations were almost always lower than coarse particle matter (CPM) concentrations. Comparison between the PM2.5 (particulate matter lower than 2.5μg.m-3) measurements by the MOUDI and Mini-Vol sampler reveals good agreement. However, MOUDI underestimates CPM. Reflectance analysis showed that almost all the Black Carbon is found in the Mini-Vol FPM and lower stages of the MOUDI, with higher concentrations at the After-Filter. The atmospheric loading of PM 2.5 was elevated at night, mainly due to more stable atmospheric conditions. Aerosol samples were analyzed for water- soluble ions, black carbon (BC), and trace elements using a number of analytical techniques.

Forward head posture (FHP) is a forward positioning of the head relative to the trunk in the sagittal plane. This posture is one of the most prevalent poor postures in patients with head and neck pain. Rehabilitative Ultrasound Imaging (RUSI) is a reliable method to objectively evaluate muscle thickness and function. To compare thickness of cervical muscles that control both head and neck posture between asymptomatic women with and without FHP. Seventy asymptomatic women aged between 20 and 40 years, with and without FHP (35 in each group), participated in the study. The thickness of the cervical muscles (rectus capitis posterior - RCP, oblique capitis superior - OCS, semispinalis capitis - SSC, sternocleidomastoid - SCM, and longus coli - LCo) was measured using RUSI and the data was compared between the two groups. The comparison of cervical muscle thickness between women with and without FHP revealed significant difference only with regard to the muscle thickness of the SCM muscle (mean difference: 0.7mm, 95% confidence interval of the difference: 0.14, 1.26mm, p value: 0.014). The thickness of this muscle was greater in women with FHP. Tonic contraction of the SCM muscle can lead to greater thickness of this muscle in subjects with FHP.

Dirac Fermions without bulk backscattering in rhombohedral topological insulators

NASA Astrophysics Data System (ADS)

Mera Acosta, Carlos; Lima, Matheus; Seixas, Leandro; da Silva, Antônio; Fazzio, Adalberto

2015-03-01

The realization of a spintronic device using topological insulators is not trivial, because there are inherent difficulties in achieving the surface transport regime. The majority of 3D topological insulators materials (3DTI) despite of support helical metallic surface states on an insulating bulk, forming topological Dirac fermions protected by the time-reversal symmetry, exhibit electronic scattering channels due to the presence of residual continuous bulk states near the Dirac-point. From ab initio calculations, we studied the microscopic origin of the continuous bulk states in rhombohedral topological insulators materials with the space group D3d 5 (R 3 m) , showing that it is possible to understand the emergence of residual continuous bulk states near the Dirac-point into a six bands effective model, where the breaking of the R3 symmetry beyond the Γ point has an important role in the hybridization of the px, py and pz atomic orbitals. Within these model, the mechanisms known to eliminate the bulk scattering, for instance: the stacking faults (SF), electric field and alloy, generated the similar effect in the effective states of the 3DTI. Finally, we show how the surface electronic transport is modified by perturbations of bulk with SF.

The Brazilian pharmaceutical industry is heavily dependent on external sources of inputs, capital, and technology. However, the emergence of technological opportunities and the development of biotechnology and the decline of the patent boom and resulting advances by generic drugs have opened windows of opportunities for the local industry. The article examines the Brazilian industry's innovative behavior vis-à-vis these opportunities, showing that although the industry as a whole invests little in innovation, a few large Brazilian companies have expanded their market share and stepped up their investments in research and development, supported by public policies for innovation. Resumo: A indústria farmacêutica brasileira caracteriza-se pela grande dependência de fontes externas de insumos, capital e tecnologia. O surgimento de oportunidades tecnológicas, associadas ao desenvolvimento da biotecnologia e ao fim do boom das patentes com o consequente avanço dos medicamentos genéricos, entretanto, vem abrindo janelas de oportunidades para a indústria local. Este artigo examina o comportamento inovador da indústria brasileira à luz dessas oportunidades, revelando que, embora o conjunto da indústria mantenha baixos níveis de investimentos em inovação, um pequeno grupo de grandes empresas nacionais vem ampliando sua participação no mercado e intensificando seus investimentos em pesquisa e desenvolvimento, apoiados por políticas públicas de inovação.

ABSTRACT OBJECTIVE To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. METHODS By using data from the Health section of 2008’s Pesquisa Nacional por Amostra de Domicílio (Brazil’s National Household Sample Survey), we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. RESULTS A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. CONCLUSIONS Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making PMID:27355465

Syndemic Zika virus, HIV and unintended pregnancy call for an urgent understanding of dual method (condoms with another modern non-barrier contraceptive) and consistent condom use. Multinomial and logistic regression analysis using data from the Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher (PNDS), a nationally representative household survey of reproductive-aged women in Brazil, identified the socio-demographic, fertility and relationship context correlates of exclusive non-barrier contraception, dual method use and condom use consistency. Among women in marital and civil unions, half reported dual protection (30% condoms, 20% dual methods). In adjusted models, condom use was associated with older age and living in the northern region of Brazil or in urban areas, whereas dual method use (versus condom use) was associated with younger age, living in the southern region of Brazil, living in non-urban areas and relationship age homogamy. Among condom users, consistent condom use was associated with reporting Afro-religion or other religion, not wanting (more) children and using condoms only (versus dual methods). Findings highlight that integrated STI prevention and family planning services should target young married/in union women, couples not wanting (more) children and heterogamous relationships to increase dual method use and consistent condom use.

Description of interventions is under-reported in physical therapy clinical trials.

Hariohm, K; Jeyanthi, S; Kumar, J Saravan; Prakash, V

Amongst several barriers to the application of quality clinical evidence and clinical guidelines into routine daily practice, poor description of interventions reported in clinical trials has received less attention. Although some studies have investigated the completeness of descriptions of non-pharmacological interventions in randomized trials, studies that exclusively analyzed physical therapy interventions reported in published trials are scarce. To evaluate the quality of descriptions of interventions in both experimental and control groups in randomized controlled trials published in four core physical therapy journals. We included all randomized controlled trials published from the Physical Therapy Journal, Journal of Physiotherapy, Clinical Rehabilitation, and Archives of Physical Medicine and Rehabilitation between June 2012 and December 2013. Each randomized controlled trial (RCT) was analyzed and coded for description of interventions using the checklist developed by Schroter et al. Out of 100 RCTs selected, only 35 RCTs (35%) fully described the interventions in both the intervention and control groups. Control group interventions were poorly described in the remaining RCTs (65%). Interventions, especially in the control group, are poorly described in the clinical trials published in leading physical therapy journals. A complete description of the intervention in a published report is crucial for physical therapists to be able to use the intervention in clinical practice.

The objective of this study was to evaluate the nutritional status of children under 5 years of age in Brazil in 2009 and its association with social and demographic factors. Data from the Household Budget Survey (Pesquisa de Orçamento Familiar - POF 2008-2009) were used, in which the nutritional profile was evaluated according to the weight-for-age (W/A), height-for-age (H/A) and weight-for-height (W/H) indices (n = 14,569). The association was estimated by applying the Pearson association test, a logistic regression and a correspondence analysis. The correspondence analysis showed a higher association of thinness with children in the North and Northeast regions, in families with lower levels of income and in those of black colour/race. Overweight and obesity had a stronger relationship with children living in the South, Southeast and Central-West, in males, in those from urban areas, in those of Caucasian colour/race, in those aged 3 years and in those from families with intermediate income ranges. Overweight and obesity showed a heterogeneous spatial distribution amongst Brazilian states. A nutritional epidemiological polarisation that presents a major challenge for public health is indicated: we must reduce nutritional deficiencies and promote healthy eating habits from childhood to improve the nutritional and epidemiological profiles and mortality of the population.

Studies with functional and applicable methods and new cognitive demands involving executive function are needed to improve screening, prevention and rehabilitation of cognitive impairment and falls. to identify differences in gait, dual task performances, and history of falls between elderly people with preserved cognition, mild cognitive impairment and mild Alzheimer's disease. A cross-sectional study was conducted. The sample consisted of 40 community-dwelling older adults with preserved cognition, 40 older adults with mild cognitive impairment, and 38 older adults with mild Alzheimer's disease. The assessment consisted of anamneses, gait (measured by the 10-meter walk test), dual task (measured by the Timed Up and Go Test associated with the motor-cognitive task of calling a phone number), and history of falls in the past year. There were no differences among all groups for all variables. However, the Alzheimer's disease Group performed significantly worse in the dual task than the other groups. No item of dual task could distinguish people with preserved cognition from those with mild cognitive impairment. The groups with cognitive impairment included more fallers, and specific characteristics in history of falls between groups were identified. Dual task could distinguish Alzheimer's disease patients specifically from other cognitive profiles. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

ABSTRACT OBJECTIVE To analyze factors associated with low adherence to drug treatment for chronic diseases in Brazil. METHODS Analysis of data from Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - Brazilian Survey on Access, Use and Promotion of Rational Use of Medicines), a population-based cross-sectional household survey, based on a probabilistic sample of the Brazilian population. We analyzed the association between low adherence to drug treatment measured by the Brief Medication Questionnaire and demographic, socioeconomic, health, care and prescription factors. We used Poisson regression model to estimate crude and adjusted prevalence ratios, their respective 95% confidence interval (95%CI) and p-value (Wald test). RESULTS The prevalence of low adherence to drug treatment for chronic diseases was 30.8% (95%CI 28.8-33.0). The highest prevalence of low adherence was associated with individuals: young adults; no education; resident in the Northeast and Midwest Regions of Brazil; paying part of the treatment; poor self-perceived health; three or more diseases; reported limitations caused by a chronic disease; using five drugs or more. CONCLUSIONS Low adherence to drug treatment for chronic diseases in Brazil is relevant, and regional and demographic differences and those related to patients’ health care and therapy regime require coordinated action between health professionals, researchers, managers and policy makers.

A baixa adesão ao tratamento medicamentoso para doenças crônicas no Brasil é relevante e as diferenças regionais, demográficas e aquelas relacionadas à atenção à saúde do paciente e ao regime terapêutico requerem ações coordenadas entre profissionais de saúde, pesquisadores, gestores e formuladores de políticas para o seu enfrentamento.

Evolution of the Astronomy Concepts Along Basic Education Cycle. (Breton Title: Evolução dos Conceitos de Astronomia no Decorrer da Educação Básica.) La Evolución de los Conceptos de Astronomía Durante la Educación Básica

Although astronomy is considered one of the older sciences of humanity and that the understanding of its concepts has brought tremendous advances to Science and therefore, to society, it is observed that a significant portion of people live outside of this kind of knowledge. According to the Parâmetros Curriculares Nacionais for basic education, it is the school responsibility the dissemination of scientifically correct concepts, including those related to astronomy. Concerning this issue, we present a survey of 140 students of ninth grade of elementary school and 120 third-grade high-school students from four schools in the region of Passo Fundo/RS. We sought to determine, through a questionnaire consisting of open and multiple choice questions, the knowledge of this group of students about the basic terms and astronomical phenomena, and also verify that the hit rate increases as they advance through the different and progressive grades of primary and secondary education. Overall, the results show that the teaching of astronomy in basic education is facing problems. Of the 20 issues investigated, in 17 the indicators are similar in the correct answers given by students for elementary and middle school, revealing that many misconceptions still remain along basic education. This demonstrates that such issues are not - or are rarely - covered during these two school levels. Thus, we conclude that the discussion of concepts related to astronomy should receive greater emphasis on approaching different subjects, requiring a national action in support of their teaching. It is believed that a national action should be supported by a triple pillar of collective actors: the scientific community, semi-professional astronomy community and the school community. Finally, this pillar would be the basis for future discussions related to the performance of these protagonists as a means to promote active changes in the curricular structure, providing, in more effective ways, the learning of astronomy in basic education. Embora a astronomia seja considerada uma das ciências mais antigas da humanidade e ainda que a compreensão de seus conceitos tenha trazido enormes avanços para a Ciência e, consequentemente, para a sociedade, observa-se que uma parcela significativa de pessoas encontra-se à margem desses conhecimentos. De acordo com os Parâmetros Curriculares Nacionais para a Educação Básica, cabe à escola a difusão dos conceitos cientificamente corretos, entre eles os relacionados à área de astronomia. Pertinente a essa questão, apresenta-se uma pesquisa realizada com 140 estudantes do nono ano do ensino fundamental e com 120 estudantes da terceira série do ensino médio de quatro escolas da região de Passo Fundo/RS. Buscou-se averiguar, por meio de um questionário composto de questões abertas e de múltipla escolha, o conhecimento desse grupo de estudantes acerca de termos e fenômenos astronômicos básicos e, também, verificar se o índice de acertos cresce à medida que eles avançam nas diferentes e gradativas séries dos ensinos fundamental e médio. De modo geral, os resultados apresentados demonstram que o ensino de astronomia na educação básica enfrenta deficiências. Das 20 questões investigadas, em 17 os índices de acertos são semelhantes nas respostas dadas por estudantes de nível fundamental e médio, revelando que muitas concepções equivocadas permanecem ao longo da educação básica. Isso evidencia que tais temas não são - ou são pouco - abordados durante esses dois níveis de escolarização. Assim, conclui-se que a discussão dos conceitos relacionados com a astronomia deve receber maior ênfase na abordagem dos diferentes conteúdos, sendo necessária uma ação nacional em prol do seu ensino. Acredita-se que essa ação nacional deve estar apoiada em um pilar triplo de atores coletivos: comunidade científica, comunidade astronômica semiprofissional e comunidade escolar. Por fim, esse pilar seria a base para futuras discussões relacionadas à atuação dessas instâncias como meio de promover mudanças ativistas na estrutura curricular, proporcionando, mais efetivamente, a educação em astronomia no ensino básico. Si bien la astronomía es considerada una de las ciencias más antiguas de la humanidad y aunque la comprensión de sus conceptos haya traído enormes avances para la ciencia y, consecuentemente, para la sociedad, se observa que una parte significativa de personas se encuentran al margen de estos conocimientos. De acuerdo con los Parámetros Curriculares Nacionales para la Educación Básica, corresponde a la escuela la difusión de los conceptos científicamente correctos, entre ellos los relacionados al área de astronomía. Sobre esta cuestión, se presenta una investigación realizada con 140 estudiantes del noveno año de la enseñanza fundamental y con 120 estudiantes del tercer año de la enseñanza de nivel medio de cuatro escuelas de la región de Passo Fundo/RS. Se pretendía averiguar, por medio de un cuestionario compuesto de preguntas abiertas y de opción múltiple, el conocimiento de este grupo de alumnos sobre términos y fenómenos astronómicos básicos y, también, si el índice de aciertos crece en la medida que los alumnos avanzan a los diferentes y sucesivos años de la enseñanza fundamental y media. De modo general, los resultados demuestran que la enseñanza de astronomía en la educación básica muestra deficiencias. De los 20 asuntos investigados, 17 revelan índices de aciertos semejantes en las respuestas dadas por los estudiantes de nivel básico y medio, mostrando que muchas concepciones equivocadas permanecen a lo largo de la educación básica. Esto hace evidente que estos temas no son - o son poco - abordados durante esos niveles de escolarización. Así, puede concluirse que la discusión de los conceptos relacionados a la astronomía debe recibir un mayor énfasis en cuanto al abordaje de los diferentes contenidos, siendo necesaria una acción nacional en pro de su enseñanza. Es necesario destacar que esa acción nacional debe estar apoyada en un pilar triple de actores colectivos: comunidad científica, comunidad de astronomía semi profesional y la comunidad escolar. En fin, ese pilar sería la base para futuras discusiones relacionadas a la actuación de esas instancias como vía para promover cambios en la estructura curricular, proporcionando más efectivamente, la educación en astronomía en la enseñanza de nivel básico.

Objetivo: el objetivo de este estudio es evaluar las propiedades psicométricas del cuestionario de disfrute por el ejercicio físico (PACES) en adolescentes con sobrepeso y obesidad.Métodos: participaron 139 adolescentes con sobrepeso y obesidad: 91 niñas (edad = 13,85 ± 1,92 años; índice de masa corporal [IMC] = 26,83 ± 3,16 kg/m2) y 48 niños (edad = 14,29 ± 1,62 años; IMC = 28,31 ± 3,74 kg/m2). Para analizar el disfrute por la actividad física se empleó el cuestionario Physical Activity Enjoyment Scale (PACES).Resultados: los resultados del análisis factorial exploratorio y confirmatorio han mostrado una estructura de dos factores; a su vez el PACES presenta una consistencia interna muy alta (alfa de Cronbach = 0,908). La fiabilidad test-retest indica una buena concordancia temporal (Spearman rho = 0,815, p < 0,001). Por último, el PACES en adolescentes con sobrepeso y obesidad manifiesta una validez convergente adecuada con la intencionalidad de ser activo (MIFA), la atracción por la actividad física (CAPA), la resistencia cardiorrespiratoria y los pliegues suprailiacoy subescapular.Conclusión: los resultados confirman que el PACES es una medida válida y fiable del disfrute por la actividad física en adolescentes con sobrepeso y obesidad. El disfrute por la actividad física puede ser relevante en la participación de los adolescentes con sobrepeso y obesidad en estas actividades.

The relation between maximum systolic blood pressure (BP) during exercise and left ventricular (LV) mass is controversial. Physical activity also induces LV mass increase. The objective was to assess the relation between BP response to exercise and LV mass in normotensive men, taking into account physical activity practice. A cross-sectional study was performed. Three hundred eighteen healthy normotensive men, aged between 20 and 60 years, participated in this study. The Minnesota questionnaire was used to assess physical activity practice. An echocardiogram and a maximum exercise test were performed. LV mass was calculated and indexed to body surface area. LV hypertrophy was defined as a ventricular mass index > or =134 g/m2. BP was measured at the moment of maximum effort. Hypertensive response was considered when BP was > or =210 mm Hg. In the multiple linear regression model, maximum systolic BP was associated with LV mass index and correlation coefficient was 0.27 (SE 0.07). Physical activity practice and age were also associated with LV mass. An association between hypertensive response to exercise and LV hypertrophy was observed (odds ratio 3.16). Thus, BP response to exercise is associated with LV mass and men with systolic BP response > or =210 mm Hg present a 3-times higher risk of LV hypertrophy than those not reaching this limit. Physical activity practice is related to LV mass, but not to LV hypertrophy.

To reflect about continuing education from the perspective of Augustine of Hippo and his theories based on the construction of knowledge and the learning process. This is a theoretical reflection study whose aim is to propose dimensions of analysis, emphasizing the history and challenges of continuing education. Such dimensions analyze the production of knowledge in Augustinian pedagogy, its historical aspects and its close relationship with lifelong education in health professions. The results show the difficulty of continuing education to reach adequate importance in health services, and that of academia in appropriating the thoughts of renowned philosophers such as Augustine. This is a result of ignorance about the convergence of these principles and their relevance. Continuing education and Augustinian pedagogy walk hand in hand in terms of care, meeting the needs that originate from practice and that are reflected in it, challenging isolated knowledge and putting different areas of knowledge to work together. Refletir sobre a educação permanente na perspectiva de Agostinho de Hipona e suas teorias pautadas na construção do conhecimento e no processo de aprendizagem. Trata-se de uma reflexão teórica cujo intuito é propor dimensões de análise, enfatizando a história e os desafios da educação permanente. Tais dimensões analisam a produção do conhecimento na pedagogia agostiniana, seus aspectos históricos e sua relação próxima com a educação permanente em saúde. Revela a dificuldade da educação permanente em ter sua dimensão alcançada noserviço de saúde, tal qual a da academia de apropriar-se do pensamento de filósofos renomados como Agostinho, fruto do desconhecimento da convergência desses pressupostos e de sua relevância. Considera-se que a educação permanente e a pedagogia agostiniana caminham juntas no cuidar, atendendo às necessidades advindas da prática e nela refletida, confrontando os saberes isolados e com eles operando em conjunto.

2011-12-01

En la sociedad prevalece una tendencia generalizada hacia la inclusion de creencias y practicas pseudocientificas. Esta investigacion responde a la necesidad de analizar como la proliferacion de las pseudociencias afecta la vision que tienen los estudiantes universitarios sobre las ciencias naturales. A tales efectos, la investigadora describe las concepciones epistemologicas que tienen los estudiantes sobre las ciencias y las pseudociencias e identifica los criterios de demarcacion, entre un area y otra, que se derivan de estas concepciones. De igual modo, esta identifica las creencias y practicas pseudocientificas de mayor arraigo entre los estudiantes, destacando, a su vez, la razon de ser de las mismas. Por ultimo, la investigadora analiza las implicaciones educativas de la problematica de la demarcacion entre ciencia y pseudociencia. La investigacion es de naturaleza mixta, enmarcada en los paradigmas empirico- analitico y cualitativo. El proceso investigativo se llevo a cabo mediante la administracion del cuestionario Criterios para la demarcacion entre ciencia y pseudociencia. La parte cualitativa estuvo enmarcada en el diseno de estudio de caso, recopilando informacion mediante entrevistas semiestructuradas en dos grupos focales. La poblacion de estudio estuvo constituida por estudiantes universitarios del nivel subgraduado de la Universidad Central de Bayamon. Los resultados del estudio reflejaron las concepciones erroneas de los estudiantes sobre la naturaleza de las ciencias y las pseudociencias. Con respecto a la demarcacion entre ciencia y pseudociencia, el criterio imperante entre los universitarios es el de la verificabilidad, considerando la aplicacion del metodo cientifico como el metodo para demostrar la veracidad de las teorias cientificas. Las creencias y practicas pseudocientificas no son muy frecuentes entre los universitarios. Estos atribuyen las mismas a la prevalencia de elementos supersticiosos y al engano a que es sometida la poblacion por quienes promueven estas practicas. A partir de los resultados, la investigadora concluye que la problematica sobre la demarcacion entre ciencia y pseudociencia esta influenciada por unos procesos de ensenanza enfocados en una vision distorsionada de la ciencia, producto de la no integracion de los aspectos filosoficos, historicos y sociales de la misma.

Santacruz Sarmiento, Neida M.

Este estudio se enfoco en los "misconception" y lagunas conceptuales en temas fundamentales de Fisica como son Equilibrio Termodinamico y Estatica de fluidos. En primer lugar se trabajo con la identificacion de "misconceptions" y lagunas conceptuales y se analizo en detalle la forma en que los estudiantes construyen sus propias teorias de fenomenos relacionados con los temas. Debido a la complejidad en la que los estudiantes asimilan los conceptos fisicos, se utilizo el metodo de investigacion mixto de tipo secuencial explicativo en dos etapas, una cuantitativa y otra cualitativa. La primera etapa comprendio cuatro fases: (1) Aplicacion de una prueba diagnostica para identificar el conocimiento previo y lagunas conceptuales. (2) Identificacion de "misconceptions" y lagunas del concepto a partir del conocimiento previo. (3) Implementacion de la intervencion por medio de modulos en el topico de Equilibrio Termodinamico y Estatica de Fluidos. (4) Y la realizacion de la pos prueba para analizar el impacto y la efectividad de la intervencion constructivista. En la segunda etapa se utilizo el metodo de investigacion cualitativo, por medio de una entrevista semiestructurada que partio de la elaboracion de un mapa conceptual y se finalizo con un analisis de datos conjuntamente. El desarrollo de este estudio permitio encontrar "misconceptions" y lagunas conceptuales a partir del conocimiento previo de los estudiantes participantes en los temas trabajados, que fueron atendidos en el desarrollo de las distintas actividades inquisitivas que se presentaron en el modulo constructivista. Se encontro marcadas diferencias entre la pre y pos prueba en los temas, esto se debio al requerimiento de habilidades abstractas para el tema de Estatica de Fluidos y al desarrollo intuitivo para el tema de Equilibrio Termodinamico, teniendo mejores respuestas en el segundo. Los participantes demostraron una marcada evolucion y/o cambio en sus estructuras de pensamiento, las pruebas estadisticas de t-pareada fueron significativas para ambos modulos a pesar que en la pos prueba no todos llegaron a la respuesta correcta. El analisis cualitativo de las respuestas de los participantes confirmo la dificultad de remover "misconception" y lagunas conceptuales.

The goal of this study is to analyze nurses' leadership in intensive care units at hospitals in the state of São Paulo, Brazil, in the face of positive and negative critical incidents. Exploratory, descriptive study, conducted with 24 nurses by using the Critical Incident Technique as a methodological benchmark. Results were grouped into 61 critical incidents distributed into categories. Researchers came to the conclusion that leadership-related situations interfere with IC nurses' behaviors. Among these situations they found: difficulty in the communication process; conflicts in the daily exercise of nurses' activities; people management; and the setting of high quality care targets. Researchers identified a mixed leadership model, leading them to the conclusion that nurses' knowledge and practice of contemporary leadership theories/styles are crucial because they facilitate the communication process, focusing on behavioral aspects and beliefs, in addition to valuing flexibility. This positively impacts the organization's results. Analisar a liderança do enfermeiro em Centros de Terapia Intensiva de hospitais localizados no interior do estado de São Paulo, diante de incidentes críticos positivos e negativos. Estudo exploratório, descritivo, realizado com 24 enfermeiros, que utilizou a Técnica do Incidente Crítico como referencial metodológico. Os resultados foram agrupados em 61 incidentes críticos distribuídos em categorias. Identificou-se que situações relacionadas à liderança interferem no comportamento do enfermeiro de Terapia Intensiva, dentre elas: dificuldade no processo de comunicação, conflitos existentes no dia a dia do exercício profissional, gerenciamento de pessoas e estabelecimento de metas para o alcance da assistência qualificada. Encontrou-se um modelo misto de liderança, o que permite concluir que o conhecimento e a prática dos enfermeiros acerca de teorias/estilos contemporâneos de liderança tornam-se fundamentais, pois facilitam o processo de comunicação, focando nos aspectos comportamentais e crenças, e valorizam a flexibilidade, impactando positivamente os resultados da organização.

To analyze whether an intervention supported by free play with a self-constructed material increases the level of physical activity of students during recess. The participants were 166 children of third to sixth grade, between nine and 12 years old (average = 10.64; SS = 1.13). An experimental project was conducted with pre-test and post-test measurement, and a control group. Experimental group participants built cardboard paddles (third and fourth) and flying rings (fifth and sixth), a material they used freely for one week during recess. ActiGraph-GT3X accelerometers were used to measure physical activity. An ANOVA of repeated measures was used to find differences between groups and genders. Significant intervention effects were found in the analyzed variables: sedentary activity (F = 38.19; p < 0.01), light (F = 76.56; p < 0.01), moderate (F = 27.44; p < 0.01), vigorous (F = 61.55; p < 0.01), and moderate and vigorous (F = 68.76; p < 0.01). Significant gender differences were shown (time × group × gender) for moderate (F = 6.58; p < 0.05) and vigorous (F = 5.51; p < 0.05) activity. The self-constructed material is effective to increase the physical activity levels of children during recess; it decreases sedentary activity and light physical activity and increases the time devoted to moderate physical activity and vigorous physical activity, both in boys and in girls. The boys had an increase in vigorous physical activity and the girls in moderate physical activity. Due to its low cost, this strategy is recommended for administrators and teachers to increase the physical activity of children during recess. Analizar si una intervención basada en el juego libre con material autoconstruido aumenta el nivel de actividad física de los escolares durante el recreo. Participaron 166 niños de tercero a sexto de educación primaria, de entre nueve y 12 años de edad (media = 10,64; DE = 1,13). Se realizó un diseño experimental con medidas pretest y postest, y un grupo control. Los participantes del grupo experimental construyeron palas de cartón (tercero y cuarto) y aros voladores (quinto y sexto), material que usaron libremente durante una semana en los recreos. Se utilizaron acelerómetros ActiGraph-GT3X para medir la actividad física. Se usó un ANOVA de medidas repetidas para investigar las diferencias entre grupos y sexo. Se encontraron efectos de intervención significativos en las variables analizadas: actividad sedentaria (F = 38,19; p < 0,01), ligera (F = 76,56; p < 0,01), moderada (F = 27,44; p < 0,01), vigorosa (F = 61,55; p < 0,01), y moderada y vigorosa (F = 68,76; p < 0,01). Emergieron diferencias significativas de sexo (tiempo x grupo x sexo) para la actividad moderada (F = 6,58; p < 0,05) y vigorosa (F = 5,51; p < 0,05). El material autoconstruido es eficaz para aumentar los niveles de actividad física de los niños en el recreo; disminuye la actividad sedentaria y la actividad física ligera, y aumenta el tiempo dedicado a la actividad física moderada y actividad física vigorosa, tanto en varones como en mujeres. Los varones aumentaron más la actividad física vigorosa y las mujeres, la actividad física moderada. Por su bajo coste, se recomienda esta estrategia a gestores y profesores para incrementar la actividad física de los niños durante el recreo.

Undertake a meta-analysis to provide a quantitative synthesis of longitudinal studies that assessed the direction of effects between eating pathology and depression. A second aim was to use meta-regression to account for heterogeneity in terms of study-level effect modifiers. A systematic review was conducted on 42 studies that assessed the longitudinal relationship between eating pathology and depression. Of these 42 studies, multilevel random-effects meta-analyses were conducted on 30 eligible studies. Meta-analysis results showed that eating pathology was a risk factor for depression (rm  = 0.13) and that depression was a risk factor for eating pathology (rm  = 0.16). Meta-regression analyses showed that these effects were significantly stronger for studies that operationalized eating pathology as an eating disorder diagnosis versus eating pathology symptoms, and for studies that operationalized the respective outcome measure as a categorical variable (e.g., a diagnosis of a disorder or where symptoms were "present"/"absent") versus a continuous measure. Results also showed that in relation to eating pathology type, the effect of an eating disorder diagnosis and bulimic symptoms on depression was significantly stronger for younger participants. Eating pathology and depression are concurrent risk factors for each other, suggesting that future research would benefit from identifying factors that are etiological to the development of both constructs. Llevar a cabo un meta-análisis para proporcionar una síntesis cuantitativa de los estudios longitudinales que evaluaron la dirección de los efectos entre la alimentación patológica y la depresión. Un segundo objetivo fue utilizar la meta-regresión para dar cuenta de la heterogeneidad en términos de modificadores del efecto a nivel de estudio. MÉTODO: Una revisión sistemática se llevó a cabo en 42 estudios que evaluaron la relación longitudinal entre la alimentación patológica y la depresión. De estos 42 estudios, se realizaron meta-análisis de multinivel de efectos aleatorios en 30 estudios elegibles. Los resultados del meta-análisis mostraron que la alimentación patológica era un factor de riesgo para depresión (rm=0.13) y que la depresión era un factor de riesgo para la alimentación patológica (rm=0.16). Los análisis de meta-regresión mostraron que estos efectos eran significativamente más fuertes para estudios que operacionalizaban la alimentación patológica como un diagnóstico de trastorno de la conducta alimentaria versus síntomas de alimentación patológica, y para los estudios que operacionalizaban la medida respectiva de resultado como una variable categórica (e.g., un diagnóstico de trastorno o cuando los síntomas estaban "presentes"/"ausentes") versus una medida continua. Los resultados mostraron que en relación al tipo de alimentación patológica, el efecto de un diagnóstico de trastorno de la conducta alimentaria y síntomas bulímicos en la depresión era significativamente más fuerte para participantes más jóvenes. DISCUSIÓN: La alimentación patológica y la depresión son factores de riesgo concurrentes uno para el otro, lo que sugiere que la investigación futura se beneficiaría de identificar factores que son etiológicos al desarrollo de ambos constructos. © 2015 Wiley Periodicals, Inc.

We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The progenies were evaluated in a randomized block design with two replications at sites in two different environments: the Colégio Estadual Agrícola Antônio Sarlo, in Campos dos Goytacazes, and the Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro (PESAGRO-RIO), in Itaocara, both in the State of Rio de Janeiro. There were significant differences between families within sets in all traits, indicating genetic variability that could be exploited in future cycles. Thirty full-sib families were selected to continue the program. The selection indexes used to predict the gains were those of Mulamba and Mock, Smith and Hazel. The best results were obtained with the Mulamba and Mock index, which allowed the prediction of negative gains for the traits number of diseased ears and ears attacked by pests, number of broken plants and lodging, as well as ears with poor husk cover. It also provided higher gains for popping expansion and grain yield than with the other indexes, giving values of 10.55 and 8.50%, respectively, based on tentatively assigned random weights.

Core outcome sets for research and clinical practice.

PubMed

Chiarotto, Alessandro; Ostelo, Raymond W; Turk, Dennis C; Buchbinder, Rachelle; Boers, Maarten

This masterclass introduces the topic of core outcome sets, describing rationale and methods for developing them, and providing some examples that are relevant for clinical research and practice. A core outcome set is a minimum consensus-based set of outcomes that should be measured and reported in all clinical trials for a specific health condition and/or intervention. Issues surrounding outcome assessment, such as selective reporting and inconsistency across studies, can be addressed by the development of a core set. As suggested by key initiatives in this field (i.e. OMERACT and COMET), the development requires achieving consensus on: (1) core outcome domains and (2) core outcome measurement instruments. Different methods can be used to reach consensus, including: literature systematic reviews to inform the process, qualitative research with clinicians and patients, group discussions (e.g. nominal group technique), and structured surveys (e.g. Delphi technique). Various stakeholders should be involved in the process, with particular attention to patients. Several COSs have been developed for musculoskeletal conditions including a longstanding one for low back pain, IMMPACT recommendations on outcomes for chronic pain, and OMERACT COSs for hip, knee and hand osteoarthritis. There is a lack of COSs for neurological, geriatric, cardio-respiratory and pediatric conditions, therefore, future research could determine the value of developing COSs for these conditions.

Physical therapists' familiarity, perceptions, and beliefs about health services utilization and health seeking behaviour have not been previously assessed. The purposes of this study were to identify physical therapists' characteristics related to familiarity of health services utilization and health seeking behaviour, and to assess what health seeking behaviour factors providers felt were related to health services utilization. We administered a survey based on the Andersen behavioural model of health services utilization to physical therapists using social media campaigns and email between March and June of 2017. In addition to descriptive statistics, we performed binomial logistic regression analysis. We asked respondents to rate familiarity with health services utilization and health seeking behaviour and collected additional characteristic variables. Physical therapists are more familiar with health services utilization than health seeking behaviour. Those who are familiar with either construct tend to be those who assess for health services utilization, use health services utilization for a prognosis, and believe that health seeking behaviour is measurable. Physical therapists rated need and enabling factors as having more influence on health services utilization than predisposing and health belief factors. Physical therapists are generally familiar with health services utilization and health seeking behaviour; however, there appears to be a disconnect between what is familiar, what is perceived to be important, and what can be assessed for both health services utilization and health seeking behaviour.

The aim of this study was to evaluate genetic divergence in the 'Carioca' (beige with brown stripes) common bean cultivar used by different institutions and in 16 other common bean cultivars used in the Rede Cooperativa de Pesquisa de Feijão (Cooperative Network of Common Bean Research), by using simple sequence repeats associated with agronomic traits that are highly distributed in the common bean genome. We evaluated 22 polymorphic loci using bulks containing DNA from 30 plants. There was genetic divergence among the Carioca cultivar provided by the institutions. Nevertheless, there was lower divergence among them than among the other cultivars. The cultivar used by Instituto Agronômico do Paraná was the most divergent in relation to the Carioca samples. The least divergence was observed among the samples used by Universidade Federal de Lavras and by Embrapa Arroz e Feijão. Of all the cultivars, 'CNFP 10104' and 'BRSMG Realce' showed the greatest dissimilarity. The cultivars were separated in two groups of greatest similarity using the Structure software. Genetic variation among cultivars was greater than the variation within or between the groups formed. This fact, together with the high estimate of heterozygosity observed and the genetic divergence of the samples of the Carioca cultivar in relation to the original provided by Instituto Agronômico de Campinas, indicates a mixture of cultivars. The high divergence among cultivars provides potential for the utilization of this genetic variability in plant breeding.

Lichens have been used in studies of environmental pollution monitoring of various air pollutants, especially heavy metals. This paper aims to study the possibility of using this specimen for the assessment of radionuclides deposition in the vicinity of a nuclear research institute, Instituto de Pesquisas Energéticas e Nucleares (IPEN) located in São Paulo, Brazil. This Institute has as major activity to perform research in the field of the nuclear fuel cycle, and therefore deals with considerable amounts of natural radionuclides of the U and Th series. The activity of the naturally occurring radionuclides U-238, Ra-226, Ra-226 and Pb-210 was determined in samples of lichen (Canoparmelia texana) and soil collected at IPEN campus. The concentrations of Ra-228, Ra-226 and Pb-210 were determined by measuring alpha and beta gross counting in a gas flow proportional detector; U and Th were determined by neutron activation analysis. The values obtained varied from 164 Bq/kg to 864 Bq/kg, 13 Bq/kg to 50 Bq/kg, and from 287 Bq/kg to 730 Bq/kg for Ra-228, Ra-226 and Pb-210 respectively. For natural U and Th the values obtained varied from 1.2 Bq/kg to 162 Bq/kg and 1.84 Bq/kg to 5.17 Bq/kg respectively. The results obtained so far suggest that the Canoparmelia texana can be used as radionuclide monitor in the vicinity of nuclear installations.

The Jebsen-Taylor Test evaluates upper limb function by measuring timed performance on everyday activities. The test is used to assess and monitor the progression of patients with Parkinson disease, cerebral palsy, stroke and brain injury. To analyze the reliability, internal consistency and validity of the Jebsen-Taylor Test in people with Muscular Dystrophy and to describe and classify upper limb timed performance of people with Muscular Dystrophy. Fifty patients with Muscular Dystrophy were assessed. Non-dominant and dominant upper limb performances on the Jebsen-Taylor Test were filmed. Two raters evaluated timed performance for inter-rater reliability analysis. Test-retest reliability was investigated by using intraclass correlation coefficients. Internal consistency was assessed using the Cronbach alpha. Construct validity was conducted by comparing the Jebsen-Taylor Test with the Performance of Upper Limb. The internal consistency of Jebsen-Taylor Test was good (Cronbach's α=0.98). A very high inter-rater reliability (0.903-0.999), except for writing with an Intraclass correlation coefficient of 0.772-1.000. Strong correlations between the Jebsen-Taylor Test and the Performance of Upper Limb Module were found (rho=-0.712). The Jebsen-Taylor Test is a reliable and valid measure of timed performance for people with Muscular Dystrophy. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

To understand the nursing professionals' conceptions of teamwork and their elements. A qualitative study conducted in an oncological hospital using a semi-structured interview with 21 nursing professionals. Two conceptions emerged from the accounts: teamwork restricted to nursing professionals and teamwork with interprofessional collaboration with particular importance for interactive dimensions: communication, trust and professional bonds, mutual respect and recognition of the other's work, collaboration, and conflict, with this last subcategory considered as an obstacle to teamwork. Nursing conceives teamwork as an interprofessional practice, which is a result of the quality of interaction among professionals from different areas and involves the recognition and handling of conflicts. Compreender as concepções dos profissionais de enfermagem sobre trabalho em equipe e seus elementos constituintes. Pesquisa qualitativa, realizada em hospital oncológico, por meio de entrevista semiestruturada com 21 profissionais de enfermagem. Duas concepções emergiram dos relatos, trabalho em equipe circunscrito à enfermagem e trabalho em equipe com colaboração interprofissional, com destaque para dimensão interativa: comunicação, confiança e vínculo, respeito mútuo e reconhecimento do trabalho do outro, colaboração e conflito. Esta última subcategoria foi apontada como obstáculo para o trabalho em equipe. A enfermagem concebe majoritariamente o trabalho em equipe como ação interprofissional, e isto decorre da qualidade da interação entre os profissionais das diferentes áreas e o reconhecimento e manejo de conflitos.

Pharmaceutical lobbying in Brazil: a missing topic in the public health research agenda.

PubMed

Paumgartten, Francisco José Roma

2016-12-22

In the US, where registration of lobbyists is mandatory, the pharmaceutical industry and private health-care providers spend huge amounts of money seeking to influence health policies and government decisions. In Brazil, where lobbying lacks transparency, there is virtually no data on drug industry expenditure to persuade legislators and government officials of their viewpoints and to influence decision-making according to commercial interests. Since 1990, however, the Associação da Indústria Farmacêutica de Pesquisa (Interfarma - Pharmaceutical Research Industry Association), Brazilian counterpart of the Pharmaceutical Research and Manufacturers of America (PhRMA), main lobbying organization of the US pharmaceutical industry, has played a major role in the advocacy of interests of major drug companies. The main goals of Interfarma lobbying activities are: shortening the average time taken by the Brazilian regulatory agency (ANVISA) to approve marketing authorization for a new drug; making the criteria for incorporation of new drugs into SUS (Brazilian Unified Health System) more flexible and speeding up technology incorporation; changing the Country's ethical clearance system and the ethical requirements for clinical trials to meet the need of the innovative drug industry, and establishing a National Policy for Rare Diseases that allows a prompt incorporation of orphan drugs into SUS. Although lobbying affects community health and well-being, this topic is not in the public health research agenda. The impacts of pharmaceutical lobbying on health policies and health-care costs are of great importance for SUS and deserve to be investigated.

The hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks. The aim of this study was to assess the effects of hammock positioning on behavioral status, vital signs, and pain in very low birth weight preterm newborns. This is a quasi-experimental/case series study in which premature infants (<1500g) were positioned in supine for one hour in a hammock. The preterm newborns were assessed 10min before, during (2, 20, 40, and 60min), and 10min after hammock positioning with the Brazelton Neonatal Behavioral Assessment Scale, vital signs and pain by the Neonatal Facial Coding System. 28 preterm infants between 28 and 36 weeks of gestational age were evaluated. Regarding the behavioral state, the preterm newborns progressively evolved to light or deep sleep during hammock positioning. There was a statistically significant reduction of the heart and respiratory rate from 2 to 60th minute in a hammock, which was maintained after the positioning. The oxygen saturation remained within normal values. No changes in pain scores were observed. The hammock positioning can be considered a safe method of positioning that can be used to reduce the stress levels in very low birth weight preterm newborns. We did not observe worsening in either pain or vital signs. Copyright © 2018 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia. Publicado por Elsevier Editora Ltda.

Vineyard soils are frequently polluted with high concentrations of copper due application of copper sulfate in order to control fungal diseases. Bioremediation is an efficient process for the treatment of contaminated sites. Efficient copper sorption bacteria can be used for bioremoval of copper from contaminated sites. In this study, a total of 106 copper resistant bacteria were examined for resistance to copper toxicity and biosorption of copper. Eighty isolates (45 from vineyard Mollisol, 35 from Inceptisol) were obtained from EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) experimental station, Bento Gonçalves, RS, Brazil (29°09′53.92″S and 51°31′39.40″W) and 26 were obtained from copper mining waste from Caçapava do Sul, RS, Brazil (30°29′43.48″S and 53′32′37.87W). Based on resistance to copper toxicity and biosorption, 15 isolates were identified by 16S rRNA gene sequencing. Maximal copper resistance and biosorption at high copper concentration were observed with isolate N2 which removed 80 mg L−1 in 24 h. Contrarily isolate N11 (Bacillus pumilus) displayed the highest specific copper biosorption (121.82 mg/L/OD unit in 24 h). GenBank MEGABLAST analysis revealed that isolate N2 is 99% similar to Staphylococcus pasteuri. Results indicate that several of our isolates have potential use for bioremediation treatment of vineyards soils and mining waste contaminated with high copper concentration. PMID:24031606

To compare a gel made with chamomile (Chamomilla recutita) with a cream of urea as an intervention to delay the time to occurrence of radiation dermatitis. Radiation dermatitis is one of the most common adverse effects of radiotherapy in patients with head and neck cancer. It is characterized by erythema, itching, pain, skin breakage and burning sensation, and there is no consensus on how to prevent it. The study is a randomized controlled clinical trial. We will recruit 48 individuals with head and neck cancer who will be starting their radiotherapy and randomize them to receive either gel of chamomile or cream of urea, as an intervention for prevention of radiation dermatitis. Social-demographic data will be collected at baseline, and clinical data will be collected before the initiation of radiotherapy. Participants will be followed weekly to assess development of radiation dermatitis. The protocol is funded by Conselho Nacional de Pesquisa e Desenvolvimento Científico (Brazil). The study was approved by a research ethics committee. Given the clinical relevance of preventing radiation dermatitis and the lack of evidence supporting specific preventive interventions, it is important to study new products that might be efficacious to prevent this complication. This article presents the protocol of a randomized controlled trial comparing a gel made with chamomile (intervention) with a cream of urea (control) to prevent radiation dermatitis in patients with head and neck cancer undergoing radiotherapy. © 2016 John Wiley & Sons Ltd.

OBJECTIVE To estimate the burden of type 2 diabetes mellitus and its percentage attributable to overweight and obesity in Brazil. METHODS The burden of diabetes mellitus was described in terms of disability-adjusted life years, which is the sum of two components: years of life lost and years lived with disability. To calculate the fraction of diabetes mellitus attributable to overweight, obesity, and excess weight, we used the prevalence of these risk factors according to sex and age groups (> 20 years) obtained from the 2008 Pesquisa Dimensões Sociais das Desigualdades (Social Dimensions of Inequality Survey) and the relative risks derived from the international literature. RESULTS Diabetes mellitus accounted for 5.4% of Brazilian disability-adjusted life years in 2008, with the largest fraction attributed to the morbidity component (years lived with disability). Women exhibited higher values for disability-adjusted life years. In Brazil, 49.2%, 58.3%, and 70.6% of diabetes mellitus in women was attributable to overweight, obesity, and excess weight, respectively. Among men, these percentages were 40.5%, 45.4%, and 60.3%, respectively. Differences were observed with respect to Brazilian regions and age groups. CONCLUSIONS A large fraction of diabetes mellitus was attributable to preventable individual risk factors and, in about six years, the contribution of these factors significant increased, particularly among men. Policies aimed at promoting healthy lifestyle habits, such as a balanced diet and physical activity, can have a significant impact on reducing the burden of diabetes mellitus in Brazil.

Several radioisotopes are produced at Instituto de Pesquisas Energéticas e Nucleares for the use in medical treatments, including the activation of 192Ir sources. These sources are suitable for brachytherapy treatments, due to their low or high activity, depending on the concentration of 192Ir, easiness to manufacture, small size, stable daughter products and the possibility of re-utilization. They may be used for the treatment of prostate, cervix, head and neck, skin, breast, gallbladder, uterus, vagina, lung, rectum, and eye cancer treatment. In this work, the use of some 192Ir sources was studied for the treatment of esophagus cancer, especially the dose determination of important structures, such as those on the mediastinum. This was carried out utilizing a FASH anthropomorphic phantom and the MCNP5 Monte Carlo code to transport the radiation through matter. It was possible to observe that the doses at lungs, breast, esophagus, thyroid and heart were the highest, which was expected due to their proximity to the source. Therefore, the data are useful to assess the representative dose specific to brachytherapy treatments on the esophagus for radiation protection purposes. The use of brachytherapy sources was studied for the treatment of esophagus cancer. FASH anthropomorphic phantom and MCNP5 Monte Carlo code were employed. The doses at lungs, breast, esophagus, thyroid and heart were the highest. The data is useful to assess the representative doses of treatments on the esophagus.

Over recent years there has been a paradigm shift towards a patient-centred biopsychosocial care model in physical therapy. This new paradigm features a growing interest in understanding the contextual factors that influence the patient's experience of disease, pain and recovery. This includes generalized consensus regarding the importance of establishing a therapeutic relationship that is centred on the patient. To explore physical therapists' perceptions and experiences regarding barriers and facilitators of therapeutic patient-centred relationships in outpatient rehabilitation settings. This is a qualitative study with four focus groups including twenty-one physical therapists. Two researchers conducted the focus groups, using a topic guide with predetermined questions. The focus group discussions were audiotaped and videotaped, transcribed verbatim and analysed thematically using a modified grounded theory approach. Physical therapists perceived that the therapeutic patient-centred relationship not only depends on the personal qualities of the professional, but also on the patient's attitudes and the characteristics of the context, including the organization and team coordination. Although being more linked towards the patients' contextual factors and needs than towards the practice of the profession, a therapeutic relationship is worth considering by physical therapists. Furthermore this study highlights the need for physical therapists and administrators to rethink the situation and propose strategies for improvement.

Scientific and technological development is crucial for advancing the Brazilian health system and for promoting quality of life. The way in which the Brazilian Ministry of Health has supported clinical research to provide autonomy, self-sufficiency, competitiveness and innovation for the healthcare industrial production complex, in accordance with the National Policy on Science, Technology and Innovation in Healthcare, was analyzed. Descriptive investigation, based on secondary data, conducted at the Department of Science and Technology, Ministry of Health. The Ministry of Health's research management database, PesquisaSaúde, was analyzed from 2002 to 2009, using the key word "clinical research" in the fields "primary sub-agenda" or "secondary sub-agenda". The 368 projects retrieved were sorted into six categories: basic biomedical research, preclinical studies, expanded clinical research, clinical trials, infrastructure support and health technology assessment. From a structured review on "clinical research funding", results from selected countries are presented and discussed. The amount invested was R$ 140 million. The largest number of projects supported "basic biomedical research", while the highest amounts invested were in "clinical trials" and "infrastructure support". The southeastern region had the greatest proportion of projects and financial resources. In some respects, Brazil is ahead of other BRICS countries (Russia, India, China and South Africa), especially with regard to establishing a National Clinical Research Network. The Ministry of Health ensured investments to encourage clinical research in Brazil and contributed towards promoting cohesion between investigators, health policies and the healthcare industrial production complex.

In the context of the modern agriculture, pest control is important in order to increase productivity in maize (Zea mays L.). However, this control should be done rationally, prioritising environmentally safer methods such as biological control. This paper aims to report the occurrence of Dolichozele koebelei Viereck, 1911 (Hymenoptera: Braconidae) in Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) larvae collected in maize subjected to different cropping systems. The experiment was conducted at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS) in Sete Lagoas, Minas Gerais State, Brazil, using organic and conventional production. Ten plants were sampled from each of the 24 plots and for each production system, three times a week during the entire cycle of maize (variety BR 106). In the laboratory, larvae were distributed in individual rearing containers with artificial diet until the end of the biological cycle. An increased number of S. frugiperda larvae was observed in organic single crop maize; hence a higher percentage of S. frugiperda larvae parasitised by Hymenoptera and Diptera also occurred in the maize under this production system. Dolichozele koebelei had not yet been described in association with larvae of S. frugiperda. The percentage of parasitism of S. frugiperda larvae was high in both experiments, indicating the importance of natural control agents in reducing the population density of S. frugiperda, and especially the importance of an appropriate crop management.

The systematic assessment of child development in the first years of life is an essential component of pediatric health checkups. The Ages and Stages Questionnaire, third edition (ASQ-3) is the most validated scale, and has been recommended by the UNICEF to verify if children have a normal neurological development. It is a monitoring instrument to assess the main developmental areas, including communication, gross motor, fine motor, personal-social, and problem solving skills, and to compare the local population to the international development standards. To validate the ASQ-3 in a pediatric population group. Children aged 1-66 months were assessed at a public hospital by pediatricians, psychologists, and educational psychologists. The SSPS software package was used to determine population scales. In 630 children, who had a homogeneous sex distribution, an 88% sensibility and a 94% specificity were determined, with a positive predictive value of 88% and a negative predictive value of 96%, compared to the National Screening Test (Prueba Nacional de Pesquisa, PRUNAPE) and the cut-off scores for each age group. The ASQ-3 established that 19.5% of children were at risk of experiencing neurodevelopmental disorders. The ASQ-3 met psychometric properties compared to the PRUNAPE, which is the gold standard for the targeted and systematic assessment of developmental milestones during health checkups in a rapid, simple and cost-effective manner, so it was considered useful to monitor child neurological development.

Objetivos: los objetivos de este estudio fueron analizar el nivel nutricional en una población de niños y adolescentes colombianos y determinar la posible relación entre el nivel nutricional y el estado nutricional según el índice de masa corporal (IMC) y la circunferencia de cintura (CC).Material y métodos: estudio transversal en 6.383 niños y adolescentes de entre 9 y 17,9 años de edad, de Bogotá, Colombia. Se aplicó de manera autodiligenciada el cuestionario Krece Plus validado en el estudio enKid como indicador del nivel nutricional con las categorías alto (test ≥ 9), medio (test 6-8) y bajo (test ≤ 5). Se tomaron medidas de peso, talla, CC, y se calculó el IMC como marcadores del estado nutricional.Resultados: de la población general, el 57,9% eran chicas (promedio de edad 12,7 ± 2,3 años). En todas las categorías del IMC, más del 50% de chicos y chicas siguen una dieta de muy baja calidad, que empeora progresivamente con el avance en edad. En ambos sexos, se observaron tendencias entre un nivel nutricional muy bajo con el desarrollo de sobrepeso. Asimismo, la obesidad abdominal por CC se relacionó con una puntuación baja en el Krece Plus en ambos sexos.Conclusiones: en escolares de Bogotá, una dieta de muy baja calidad se relacionó con alteraciones del estado nutricional (IMC y CC), especialmente entre chicas y adolescentes. Estos resultados deben alentar el desarrollo de intervenciones orientadas a mejorar los hábitos nutricionales entre los escolares colombianos.

Objetivo: El objetivo principal del presente estudio consistió en determinar la prevalencia de los cambios en la interfase vitreomacular (IVM) mediante tomografía de coherencia óptica (OCT) en la población general. En segundo lugar, se describieron otros cambios de la OCT. Métodos: Las anomalías en la IVM se diagnosticaron mediante OCT y se distribuyeron de acuerdo con la clasificación del grupo International Vitreomacular Traction Study (estudio internacional de tracción vitreomacular, IVTS, por sus siglas en inglés) y se dividieron en 3 grados según John et al. [Retina 2014;34:442-446]. Resultados: La prevalencia calculada de anomalías vitreomaculares en la población belga de ≥50 años fue del 1,17% [intervalo de confianza (IC 0,38-3,62)] en el caso de tracción vitreomacular (TVM) focal de grado 1; del 0,39% (IC 0,05-2,76) en el caso de TVM focal de grado 2; del 8,17% (IC 5,33-12,53) en el caso de adhesión vitreomacular focal; y del 17,9% (IC 13,41-23,9) en el caso de adhesión vitreomacular difusa. Conclusiones: Se presentó la prevalencia de anomalías vitreomaculares en un estudio de cohortes belga. Estos resultados concuerdan en gran medida con los datos presentados previamente sobre la prevalencia de la TVM. Un conocimiento correcto sobre la epidemiología de las alteraciones en la IVM y un diagnóstico temprano permitirán una intervención satisfactoria. © 2017 S. Karger AG, Basel.

El objetivo principal del artículo es estudiar la asociación entre la percepción subjetiva sobre la situación económica propia y una serie de medidas objetivas de bienestar socioeconómico –fuentes de ingresos, tenencia de vivienda, nivel educativo y transferencias familiares informales de dinero- entre adultos mayores de dos países Latinoamericanos: México y Costa Rica. Los datos se obtienen de las primeras rondas de dos encuestas sobre envejecimiento: CRELES para Costa Rica y ENASEM para México. La variable dependiente más importante se obtiene de las respuestas a las pregunta “¿Cómo califica su situación económica actual?” en Costa Rica y “¿Diría usted que su situación económica es…?” en México. Para ambas encuestas, las respuestas se codificaron en forma binaria; el código 0 representa las categorías Excelente, Muy buena y Buena, y el código 1 representa a las categorías Regular y Mala. Se encontró que el ingreso por jubilación es un importante determinante de la percepción de bienestar en ambos países. En Costa Rica, el ingreso del cónyuge y la tenencia de vivienda son importantes predictores de la percepción de bienestar, mientras que en México, los ingresos por transferencias están fuertemente asociados con dicha percepción.

RESUMEN La comunicación sobre sexualidad entre padres/madres y adolescentes enfrenta dificultades particulares producto de factores socioculturales. Este estudio tuvo como objetivo documentar las actitudes de padres/madres y adolescentes hacia la comunicación sobre temas de sexualidad. Los resultados emanan de la medición inicial del Proyecto Cuídalos. Los datos de este estudio forman parte de un estudio amplio que evaluó un módulo interactivo basado en la web para mejorar comunicación sobre temas de salud entre padres/madres y adolescentes entre 13–17 años. En este artículo, reportamos datos basales que contestaron los/as participantes sobre comodidad al hablar sobre temas de salud sexual. La muestra, de los datos aquí expuestos, estuvo compuesta por 458 diadas de madres/padres y sus hijos/as adolescentes (n=916). Se realizó análisis de frecuencias y medidas de tendencia central con los datos obtenidos inicialmente. La edad promedio de los adolescentes fue de 15 años, de los que un 15% se encontraban activos sexualmente. Los/as adolescentes tienen mejor disposición que los/as padres/madres para hablar sobre sexualidad. Sin embargo, los/as padres/madres entienden que comparten suficiente información sobre temas relacionados a la sexualidad. Los/as padres/madres y adolescentes reportaron algún grado de dificultad e incomodidad al hablar sobre métodos específicos de prevención. Los resultados destacan la necesidad de incorporar a los/as padres/madres en intervenciones con adolescentes sobre temas de salud sexual. En Puerto Rico es necesario desarrollar programas dirigidos a minimizar las conductas sexuales de alto riesgo en jóvenes. PMID:28736599

A disponibilidade de bases de dados cada vez mais complexas e multidimensionais é um dos principais motivadores para o aumento do número de estudos que utilizam análises multivariadas baseadas em lógica de conjuntos nebulosos. Apesar da disseminação do método Grade of Membership nos trabalhos empíricos brasileiros da área de ciências sociais e saúde, questões relativas à identificabilidade e estabilidade dos parâmetros finais estimados pelo programa GoM 3.4 não foram suficientemente aprofundadas. Dada a relevância de se obterem parâmetros únicos e estáveis, Guedes et al. (2010) propuseram um procedimento empírico para localizar um modelo de máximo global (MG) com parâmetros estáveis. Entretanto, seu localizador de MG não incorpora qualquer medida de variabilidade. Neste artigo, tal limitação é contornada por meio da utilização de uma estatística de ponderação – Máximo Global Ponderado (MGP) – semelhante ao coeficiente de variação. Esse indicador busca não penalizar de forma desproporcional situações nas quais os desvios médios, apesar de diferentes de zero, são muito pequenos. Apresentam-se evidências de que o localizador MGP reduz a distância do modelo identificado à real estrutura latente dos dados em análise, quando comparados ao modelo identificado pelo localizador não ponderado, MG.

To analyze the accuracy of the defining characteristics of hypothermia in newborns and to verify associations between defining characteristics and clinical variables. A cross-sectional accuracy study with statistical analysis. Slow capillary refill, decrease in ventilation, peripheral vasoconstriction, and insufficient weight gain were the defining characteristics with the highest specificity values, while slow gastric emptying, skin cool to touch, irritability, and bradycardia were the defining characteristics with the highest values for both sensitivity and specificity. Slow gastric emptying, skin cool to touch, irritability, and bradycardia are good clinical indicators to infer initial stages of hypothermia and to confirm its presence. Accuracy measures may contribute to the improvement of the diagnostic inferential process.

The increase in the older adult and oldest old population in Brazil is growing. This phenomenon may be accompanied by an increase in musculoskeletal symptoms such as low back pain. This condition is usually associated with disability. To verify the association between pain intensity and disability in older adults with acute low back pain and assess whether these variables differ depending on the age group and marital status. This is a cross-sectional study conducted with 532 older adults with acute low back pain episodes. Pain intensity was assessed through the Numeric Pain Scale and disability through the Late Life Function and Disability Instrument, which shows two dimensions: "frequency" and "limitation" in performing activities. The association between pain and disability was analyzed. For the interaction effect between age groups and marital status, we found that the oldest old living with a partner performed activities of the personal domain less often compared to the oldest old living alone. The oldest old group living with a partner had a lower frequency of performing activities, but did not report feeling limited. The association of pain with disability was minimal (rho<0.20) and thus considered irrelevant. Disability in older adults with acute low back pain was influenced by the interaction between age groups and marital status and is not associated with pain intensity.

Development of postural control and maturation of sensory systems in children of different ages a cross-sectional study.

PubMed

Sá, Cristina Dos Santos Cardoso de; Boffino, Catarina Costa; Ramos, Renato Teodoro; Tanaka, Clarice

To evaluate the stability, postural adjustments and contributions of sensory information for postural control in children. 40 boys and 40 girls were equally divided into groups of 5, 7, 9 and 12 years (G5, G7, G9 and G12). All children were submitted to dynamic posturography using a modified sensory organization test, using four sensory conditions: combining stable or sway referencing platform with eyes opened, or closed. The area and displacements of the center of pressure were used to determine stability, while the adjustments were used to measure the speed of the center of pressure displacements. These measurements were compared between groups and test conditions. Stability tends to increase with age and to decrease with sensory manipulation with significant differences between G5 and G7 in different measures. G7 differed from G12 under the conditions of stable and sway platform with eyes open. G9 did not differ from G12. Similar behavior was observed for adjustments, especially in anterior-posterior directions. Postural stability and adjustments were associated with age and were influenced by sensory manipulation. The ability to perform anterior-posterior adjustments was more evident and sensory maturation occurred firstly on the visual system, then proprioceptive system, and finally, the vestibular system, reaching functional maturity at nine years of age. Seven-year-olds seem to go through a period of differentiated singularity in postural control. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

Transcutaneous electrical nerve stimulation and interferential current have been widely used in clinical practice. However, a systematic review comparing their effects on pain relief has not yet been performed. To investigate the effects of transcutaneous electrical nerve stimulation and interferential current on acute and chronic pain. We use Pubmed, Embase, LILACS, PEDro and Cochrane Central Register of Controlled Trials as data sources. Two independent reviewers that selected studies according to inclusion criteria, extracted information of interest and verified the methodological quality of the studies made study selection. The studies were selected if transcutaneous electrical nerve stimulation and interferential current were used as treatment and they had pain as the main outcome, as evaluated by a visual analog scale. Secondary outcomes were the Western Ontario Macmaster and Rolland Morris Disability questionnaires, which were added after data extraction. Eight studies with a pooled sample of 825 patients were included. The methodological quality of the selected studies was moderate, with an average of six on a 0-10 scale (PEDro). In general, both transcutaneous electrical nerve stimulation and interferential current improved pain and functional outcomes without a statistical difference between them. Transcutaneous electrical nerve stimulation and interferential current have similar effects on pain outcome The low number of studies included in this meta-analysis indicates that new clinical trials are needed.

Cardiac rehabilitation (CR) is a recommended model of care for cardiovascular diseases; however, is not widely available and is underutilized, especially in low- and middle-income countries. To identify the CR programs available in one Brazilian state (Minas Gerais; MG) and describe their characteristics by funding type. In this multi-center descriptive study, CR programs were identified in four MG regions and 41 CR coordinators were sent a survey to report the characteristics of their programs, including CR components described in guidelines and barriers to patients' participation. Descriptive and comparative analysis between public and private programs were carried out. Forty-one CR programs were identified, only 21.9% public. Nineteen completed the survey. The majority of CR programs offered initial assessment and physical training. Components of comprehensive CR programs that were rarely offered included treatment of tobacco dependence, psychological support and lipid control. Physical therapists were present in all CR programs. The six-minute walk test was used in most programs to assess functional capacity. Programs were located intra-hospital only in public hospitals. Phase 2 (initial outpatient) and phase 4 (maintenance) were offered significantly more in private programs when compared to public ones. The main barrier for CR participation was the lack of referral. The availability of CR programs in MG state is low, especially public programs. Most programs do not offer all core components of CR.

OBJECTIVE To analyze conditional and unconditional healthy life expectancy among older Brazilian women. METHODS This cross-sectional study used the intercensal technique to estimate, in the absence of longitudinal data, healthy life expectancy that is conditional and unconditional on the individual’s current health status. The data used were obtained from the Pesquisa Nacional por Amostra de Domicílios (National Household Sample Survey) of 1998, 2003, and 2008. This sample comprised 11,171; 13,694; and 16,259 women aged 65 years or more, respectively. Complete mortality tables from the Brazilian Institute of Geography and Statistics for the years 2001 and 2006 were also used. The definition of health status was based on the difficulty in performing activities of daily living. RESULTS The remaining lifetime was strongly dependent on the current health status of the older women. Between 1998 and 2003, the amount of time lived with disability for healthy women at age 65 was 9.8%. This percentage increased to 66.2% when the women already presented some disability at age 65. Temporal analysis showed that the active life expectancy of the women at age 65 increased between 1998-2003 (19.3 years) and 2003-2008 (19.4 years). However, life years gained have been mainly focused on the unhealthy state. CONCLUSIONS Analysis of conditional and unconditional life expectancy indicated that live years gained are a result of the decline of mortality in unhealthy states. This pattern suggests that there has been no reduction in morbidity among older women in Brazil between 1998 and 2008. PMID:25741653

Biomass burnin is a common force in much of the developing tropical world where it has wide-ranging environmental impacts. Fire is a component of tropical deforestation and is 0 p often used to clear broad expanses of land for shifting agriculture and cattle ranching. Frequent burning in the tropical savannas is a distinct problem from that of primary forest. In Brazil, most of the burning occurs in the cerrado which occupies approximately 1,800,000 km2, primarily on the great plateau in central Brazil. Wildland and agricultural fires are dramatic sources of regional air pollution in central Brazil. Biomass burning is an important source of a large number of trace gases including greenhouse gases and other chemically active species. Knowledge of trace gas emissions from biomass burning in Brazil is limited by a number of factors, most notably relative emission factors for gases from specific fire types/fuels and accurate estimates of temporal and spatial distribution and extent of fire activity. Estimates of trace gas emissions during September 1992 will be presented that incorporates a digital map of vegetation classes, pyrogenic emission factors calculated from ground and aircraft missions, and Instituto Nacional de Pesquisas Espaciais (INPE) fire products derived from Advanced Very High Resolution Radiometer (AVHRR) data. The regional emissions calculated from National Oceanographic and Atmospheric Administration (NOAA) AVHRR estimates of fire activity will provide an independent estimate for comparison with results obtained by the National Aeronautics and Space Administration (NASA) Transport and Atmospheric Chemistry Near the Equator - Atlantic (TRACE-A) experiments.

Systematic reviews provide the best evidence about the effectiveness of healthcare interventions. Although systematic reviews are conducted with explicit and transparent methods, discrepancies might occur between the protocol and the publication. To estimate the proportion of systematic reviews of physical therapy interventions that are registered, the methodological quality of (un)registered systematic reviews and the prevalence of outcome reporting bias in registered systematic reviews. A random sample of 150 systematic reviews published in 2015 indexed on the PEDro database. We included systematic reviews written in English, Italian, Portuguese and Spanish. A checklist for assessing the methodological quality of systematic reviews tool was used. Relative risk was calculated to explore the association between meta-analysis results and the changes in the outcomes. Twenty-nine (19%) systematic reviews were registered. Funding and publication in a journal with an impact factor higher than 5.0 were associated with registration. Registered systematic reviews demonstrated significantly higher methodological quality (median=8) than unregistered systematic reviews (median=5). Nine (31%) registered systematic reviews demonstrated discrepancies between protocol and publication with no evidence that such discrepancies were applied to favor the statistical significance of the intervention (RR=1.16; 95% CI: 0.63-2.12). A low proportion of systematic reviews in the physical therapy field are registered. The registered systematic reviews showed high methodological quality without evidence of outcome reporting bias. Further strategies should be implemented to encourage registration. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia. Publicado por Elsevier Editora Ltda.

Background While the research design of articles published in medical journals and in some physical therapy journals has already been evaluated, this has not been investigated in Brazilian physical therapy journals. Objective To describe the research design used in all articles published in Brazilian scientific journals that are freely available, have high Qualis rankings, and are relevant to physical therapy over a 7-year period. Method We extracted the bibliometric data, research design, research type (human or animal), and clinical area for all articles published. The articles were grouped into their level of evidence, and descriptive analyses were performed. We calculated the frequency, proportions of articles, and 95% confidence interval of these proportions with each research design in each journal. We cross-tabulated the clinical areas with research designs (expressed as number and percentages). Results A total of 1,458 articles from four Brazilian journals were found: Revista Brasileira de Fisioterapia, Revista Fisioterapia em Movimento, Revista Fisioterapia e Pesquisa, and Revista Acta Fisiátrica. The majority of articles were classified as level II of evidence (60%), followed by level III (29%) and level I (10%). The most prevalent research designs were cross-sectional studies (38%), single-case or case-series studies, and narrative reviews. Most articles reported human research and were in the musculoskeletal, neurologic, and cardiothoracic areas. Conclusions Most of the research published in Brazilian physical therapy journals used levels II and III of evidence. Increasing the publication rate of systematic reviews and randomized controlled trials would provide more high-quality evidence to guide evidence-based physical therapy practice. PMID:24675913

To evaluate the effect of three types of exercise intervention in patients with patellofemoral pain and to verify the contributions of each intervention to pain control, function, and lower extremity kinematics. A randomized controlled, single-blinded trial was conducted. Forty women with patellofemoral pain were randomly allocated into four groups: hip exercises, quadriceps exercises, stretching exercises and a control group (no intervention). Pain (using a visual analog scale), function (using the Anterior Knee Pain Scale), hip and quadriceps strength (using a handheld isometric dynamometer) and measuring lower limb kinematics during step up and down activities were evaluated at baseline and 8 weeks post intervention. All treatment groups showed significant improvements on pain and Anterior Knee Pain Scale after intervention with no statistically significant differences between groups except when compared to the control group. Only hip and quadriceps groups demonstrated improvements in muscle strength and knee valgus angle during the step activities. Hip strengthening exercises were not more effective for pain relief and function compared to quadriceps or stretching exercises in females with patellofemoral pain. Only hip and quadriceps groups were able to decrease the incidence of dynamic valgus during step-down activity. This study was approved by Brazilian Clinical Trials Registry registration number: RBR-6tc7mj (http://www.ensaiosclinicos.gov.br/rg/RBR-6tc7mj/).

Lichens have been used in studies of environmental pollution monitoring of various air pollutants, especially heavy metals. This paper aims to study the possibility of using this specimen for the assessment of radionuclides deposition in the vicinity of a nuclear research institute, Instituto de Pesquisas Energeticas e Nucleares (IPEN) located in Sao Paulo, Brazil. This Institute has as major activity to perform research in the field of the nuclear fuel cycle, and therefore deals with considerable amounts of natural radionuclides of the U and Th series. The activity of the naturally occurring radionuclides U-238, Ra-226, Ra-226 and Pb-210 was determinedmore » in samples of lichen (Canoparmelia texana) and soil collected at IPEN campus. The concentrations of Ra-228, Ra-226 and Pb-210 were determined by measuring alpha and beta gross counting in a gas flow proportional detector; U and Th were determined by neutron activation analysis. The values obtained varied from 164 Bq/kg to 864 Bq/kg, 13 Bq/kg to 50 Bq/kg, and from 287 Bq/kg to 730 Bq/kg for Ra-228, Ra-226 and Pb-210 respectively. For natural U and Th the values obtained varied from 1.2 Bq/kg to 162 Bq/kg and 1.84 Bq/kg to 5.17 Bq/kg respectively. The results obtained so far suggest that the Canoparmelia texana can be used as radionuclide monitor in the vicinity of nuclear installations.« less

To evaluate the parents' perspective with regard to evolution of their child with cochlear implant (CI). This was a cross-sectional prospective study conducted at the Centro de Pesquisas Audiológicas of Hospital de Reabilitação de Anomalias Craniofaciais of Universidade de São Paulo. The selection of the sample was performed from the spontaneous demand, among the months from July to December 2011. The final sample comprised 50 parents or guardians of children using CI, with minimum 1 year and maximum of 3 years of device use. The translated and adapted to Brazilian Portuguese version of the questionnaire "Perspectives of parents of children with cochlear implants" was applied. This instrument consists of 74 questions and allows quantification of the parents' perspective on subscales that illustrate the situation of the child and family. Each question has five options scored from one to five responses. The Spearman test for comparison of results between the subscales was applied. The social relationships, self-sufficiency, and communication subscales showed the highest mean score, whereas the worst score was for child support subscale, reflecting the independence and autonomy of the patients. The correlation between the child subscales was realized, and the results showed themselves significant and positive for communication subscale of communication with all others subscales. The family subscales also had a positive correlation with the communication, education, and self-sufficiency. These results demonstrate that parents have good expectations regarding communication, independence, and social participation of children after CI surgery, and this questionnaire is a useful tool for use in clinical practice.

Sports that require the constant use of an upper limb demand the maximum kinetic chain efficiency in this segment. Immaturity of the musculoskeletal system, followed by failure in motor skills can expose adolescents to major reports of pain complaints, particularly for the shoulder. To evaluate the prevalence of shoulder pain in adolescent athletes and identify possible factors associated with the complaint. A total of 310 athletes, of both sexes and aged between 10 and 19 years old participated on this study. The subjects filled out a questionnaire with personal, sports and upper limb function (Quick-DASH) questions. We evaluated the height, body mass, shoulder rotation range and stability of the upper limb using the CKCUES-test. The association between pain and the variables was analyzed using multilevel modeling logistic regression. We used the Mann-Whitney test for comparing between pain and function. The prevalence of shoulder pain was 43.5%. Athletes between 15 and 19 years, handball and judo practitioners, are 1.86, 2.14 and 3.07 more likely to report shoulder pain, respectively, when compared with other sports and ages. Shoulder pain reduced function scores (p<0.001) and increased changes in the range of motion (p<0.04). Shoulder pain is highly prevalent and is associated especially with older adolescent athletes of handball and judo, and affects the levels of function and the range of the shoulder.

To evaluate psychiatric comorbidities in outpatients receiving care for HIV and Chagas disease at Instituto de Pesquisa Clínica Evandro Chagas (IPEC), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brazil. Cross-sectional study with a consecutive sample of 125 patients referred to an outpatient psychiatric clinic from February to December 2010. The Mini International Neuropsychiatric Interview (MINI) was used. Factors associated with more frequent mental disorders were estimated by odds ratios (OR) with 95% confidence intervals (95%CI) by multiple logistic regression. Seventy-six (60.8%) patients with HIV, 40 (32%) patients with Chagas disease, and nine (7.2%) patients with human T-lymphotropic virus were interviewed. The majority were women (64%), with up to 8 years of formal education (56%), and unemployed (81.6%). The median age was 49 years. Suicide risk (n=71) (56%), agoraphobia (n=65) (52%), major depressive episode (n=56) (44.8%), and alcohol/drug abuse (n=43) (34.4%) predominated, the latter being directly associated with lower family income (OR = 2.64; 95%CI 1.03-6.75) and HIV infection (OR = 5.24; 95%CI 1.56-17.61). Suicide risk was associated with non-white skin color (OR = 2.21; 95%CI 1.03-4.75), unemployment (OR = 2.72; 95%CI 1.01-7.34), and diagnosis of major depression (OR = 3.34; 95%CI 1.54-7.44). Measures targeting adverse socioeconomic conditions and psychiatric and psychological monitoring and care should be encouraged in this population, considering the association with abuse of alcohol/other psychoactive drugs and suicide risk.

Previous studies have shown positive results of phototherapy for improving performance and accelerating recovery; however, the effects of phototherapy during training and after a primary adaptation remain unclear. The aim of this randomized controlled trial is to analyze the effects of phototherapy and combined training on clinical, functional, and psychological outcomes and on vascular endothelial growth factor. This randomized placebo-controlled trial by stratified sample will involve 45 healthy male participants. In phase 1, the participants will undergo six weeks of combined training (sprints and squats). In phase 2, participants will be allocated through stratified randomization (based on adaptation capacity) into three groups: active phototherapy group (AG), placebo group (PG), and non-treatment control group (CG). A new six-week training program will then start and the participants will receive the recovery strategy between sprints and squats. The primary outcome will be maximal isometric contraction. The secondary outcomes include strength and power testing, maximal incremental test, squat jump, sprint test, muscle soreness, pain threshold, perceptions of exertion and recovery, psychological questionnaire, and vascular endothelial growth factor. This will be the first trial to include phototherapy during training. We believe that this strategy will combine the ergogenic and prophylactic effects in the same session. Furthermore, an application protocol performed after primary adaptation may reflect the real effect of the technique.

Pap smears are the most common and inexpensive screening method for cervical cancer. We analyzed micronucleus prevalence in exfoliated cervical mucosa cells, to investigate associations between increased numbers of micronuclei and risk factors for cervical cancer. Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON). Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners), age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN) were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. Comparisons between groups with active (7.9 +/- 7.8) and passive (7.2 +/- 10.6) smoking versus no smoking (3.7 +/- 5.1); with/without alcoholism (7.8 +/- 1.4 and 6.9 +/- 10.1); with/without inflammatory cytology (10.7 +/- 10.5 and 1.3 +/- 1.7); and with CIN I, II and III and no CIN (respectively 4.3 +/- 4.3, 10.6 +/- 5.3, 22.7 +/- 11.9 and 1.3 +/- 1.4) found elevated micronucleus prevalence (P < 0.05). We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

The recent engagement of Brazil in the construction and utilization of the International Space Station has motivated several Brazilian research institutions and universities to establish study centers related to Space Sciences. The Pontificia Universidade Catolica do Rio Grande do Sul (PUCRS) is no exception. The University initiated in 1993 the first degree course training students to operate commercial aircraft in South America (the School of Aeronautical Sciences. A further step was the decision to build the first Brazilian laboratory dedicated to the conduct of experiments in ground-based microgravity simulation. Established in 1998, the Microgravity Laboratory, which was located in the Instituto de Pesquisas Cientificas e Tecnologicas (IPCT), was supported by the Schools of Medicine, Aeronautical Sciences and Electrical Engineering/Biomedical Engineering. At the end of 2006, the Microgravity Laboratory became a Center and was transferred to the School of Engineering. The principal activities of the Microgravity Centre are the development of research projects related to human physiology before, during and after ground-based microgravity simulation and parabolic flights, to aviation medicine in the 21st century and to aerospace biomedical engineering. The history of Brazilian, and why not say worldwide, space science should unquestionably go through PUCRS. As time passes, the pioneering spirit of our University in the aerospace area has become undeniable. This is due to the group of professionals, students, technicians and staff in general that have once worked or are still working in the Center of Microgravity, a group of faculty and students that excel in their undeniable technical-scientific qualifications.

Estrelas de bário são gigantes vermelhas de tipo GK que apresentam excessos atmosféricos dos elementos do processo-s. Tais excessos são esperados em estrelas na fase de pulsos térmicos do AGB (TP-AGB). As estrelas de bário são, no entanto, menos massivas e menos luminosas que as estrelas do AGB, assim, não poderiam ter se auto-enriquecido. Seu enriquecimento teria origem em uma estrela companheira, inicialmente mais massiva, que evolui pelo TP-AGB, se auto-enriquece com os elementos do processo-s e transfere material contaminado para a atmosfera da atual estrela de bário. A companheira evolui então para anã branca deixando de ser observada diretamente. As estrelas de bário são, portanto, úteis como testes observacionais para teorias de nucleossíntese pelo processo-s, convecção e perda de massa. Análises detalhadas de abundância com dados de alta qualidade para estes objetos são ainda escassas na literatura. Neste trabalho construímos modelos de atmosferas e, procedendo a uma análise diferencial, determinamos parâmetros atmosféricos e evolutivos de uma amostra de dez gigantes de bário e quatro normais. Determinamos seus padrões de abundância para Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, Sm, Eu e Gd, concluindo que algumas estrelas classificadas na literatura como gigantes de bário são na verdade gigantes normais. Comparamos dois padrões médios de abundância, para estrelas com grandes excessos e estrelas com excessos moderados, com modelos teóricos de enriquecimento pelo processo-s. Os dois grupos de estrelas são ajustados pelos mesmos parâmetros de exposição de nêutrons. Tal resultado sugere que a ocorrência do fenômeno de bário com diferentes intensidades não se deve a diferentes exposições de nêutrons. Discutimos ainda efeitos nucleossintéticos, ligados ao processo-s, sugeridos na literatura para os elementos Cu, Mn, V e Sc.

Formulado no final da década de 50, o modelo de percolação concentra-se em descrever o meio poroso, que será visto neste trabalho como uma rede de canais aleatórios, por onde escoa um fluido determinístico. Se o número de canais for suficientemente grande, então eles estarão ligados e o meio se tornará permeável à passagem do fluido. Neste caso, dizemos que houve a percolação do fluido. Reformulando o modelo acima, podemos escrever um código particularmente adaptado para simulações em Galáxias, onde iremos supor que os canais formam um reticulado, e que cada sítio da rede representa um poro que será interpretado como uma região ativa de formação estelar. Para cada elo teremos um pequeno canal ligando dois sítios vizinhos, que poderá, após um tempo "t", induzir ou não a formação de uma região ativa no poro vizinho. Para simular a passagem desta região ativa através dos poros, diremos que um elo está aberto com probabilidade p e fechado com probabilidade 1-p. Dessa forma, passamos a imaginar configurações de elos abertos e fechados, onde cada configuração ocorre com uma certa probabilidade, dada por p|A|(1-p)|F|, onde |A| é o número de elos abertos e |F| o número de elos fechados da configuração. A expressão anterior só tem importância física se |A| e |F| forem ambos finitos, pois, caso contrário, a probabilidade de ocorrência de uma dada configuração será sempre nula. Neste trabalho, foram considerados dados cinemáticos publicados na literatura bem como aqueles obtidos pelos autores a partir de observações fotométricas realizadas no Observatório de Las Campanãs, em 1994, para a Galáxia Anelada Peculiar HRG 03401. Mostraremos que para certos valores de p, situados entre 0,5 e 0,6, os clusters assim formados irão simular, de maneira coerente, o referido objeto.

Health, development and innovation: a contribution of the critical theory of technology to the discussion.

The relationships between health and socioeconomic development are diverse. These relationships find in the health economic complex a privileged ground for expression. The importance of health technologies increased exponentially since the middle of the 20th century, affecting health systems in terms of both, quality of care and economic aspects. In fact, the predominant model of care is based on fragmented, symptomatic therapy practices that encourages the use of products and services and promotes a passive participation of users rather than humanization of care. Overcoming this model requires changes in the health technology standards which, in turn, require changes in the technology standard of society. The critical theory of technology helps to understand the evolution of the industrial civilization. It enriches the discussion by suggesting the health economic complex be more sensibly adjusted to the requirements of comprehensive health care, and to inclusive and sustainable development. Resumo: As relações entre a saúde e o desenvolvimento socioeconômico são múltiplas. Essas relações têm o complexo econômico da saúde como o espaço privilegiado de sua expressão. A importância das tecnologias de saúde aumentou exponencialmente desde meados do século XX, com efeitos sobre os sistemas de saúde, tanto em qualidade da atenção, quanto em aspectos econômicos. Na realidade, predomina um modelo de atenção caracterizado por práticas fragmentadas, que enfatizam tratamentos sintomáticos, estimulam o consumismo de produtos e serviços e promovem, ao invés da humanização, uma participação passiva dos usuários. A superação desse modelo passa pela mudança do padrão tecnológico da saúde, que, por sua vez, exige a transformação do padrão tecnológico da sociedade. A teoria crítica da tecnologia ajuda a compreender a evolução da civilização industrial. Enriquece o debate, sugerindo uma conformação do complexo econômico da saúde mais sensível às exigências da atenção integral à saúde e do desenvolvimento inclusivo e sustentável.

Resistance and aerobic training are recommended as an adjunctive treatment for hypertension. However, the number of sessions required until the hypotensive effect of the exercise has stabilized has not been clearly established. To establish the adaptive kinetics of the blood pressure (BP) responses as a function of time and type of training in hypertensive patients. We recruited 69 patients with a mean age of 63.4 ± 2.1 years, randomized into one group of resistance training (n = 32) and another of aerobic training (n = 32). Anthropometric measurements were obtained, and one repetition maximum (1RM) testing was performed. BP was measured before each training session with a digital BP arm monitor. The 50 training sessions were categorized into quintiles. To compare the effect of BP reduction with both training methods, we used two-way analysis of covariance (ANCOVA) adjusted for the BP values obtained before the interventions. The differences between the moments were established by one-way analysis of variance (ANOVA). The reductions in systolic (SBP) and diastolic BP (DBP) were 6.9 mmHg and 5.3 mmHg, respectively, with resistance training and 16.5 mmHg and 11.6 mmHg, respectively, with aerobic training. The kinetics of the hypotensive response of the SBP showed significant reductions until the 20th session in both groups. Stabilization of the DBP occurred in the 20th session of resistance training and in the 10th session of aerobic training. A total of 20 sessions of resistance or aerobic training are required to achieve the maximum benefits of BP reduction. The methods investigated yielded distinct adaptive kinetic patterns along the 50 sessions. Os treinamentos de força e aeróbio são indicados para o tratamento adjuvante da hipertensão. Entretanto, o número de sessões necessárias até estabilização do efeito hipotensor com o exercício ainda não está claramente estabelecido. Estabelecer a cinética adaptativa das respostas tensionais em função do tempo e do tipo de treinamento em hipertensos. Foram recrutados 69 hipertensos com idade média de 63,4 ± 2,1 anos, randomizados em um grupo de treinamento de força (n = 32) e outro de treinamento aeróbio (n = 32). Foram realizadas medidas antropométricas e testes de uma repetição máxima (1RM). A pressão arterial (PA) foi medida antes de cada sessão de treinamento com um aparelho de pressão digital de braço. As 50 sessões de treinamento foram categorizadas em quintis. Para comparar o efeito da redução da PA entre os métodos de treinamentos (between), utilizamos análise de covariância (ANCOVA) bifatorial ajustada para os valores de PA pré-intervenção. As diferenças entre os momentos foram estabelecidas por análise de variância (ANOVA) unifatorial. As reduções na PA sistólica (PAS) e diastólica (PAD) foram de 6,9 mmHg e 5,3 mmHg, respectivamente, com o treinamento de força e 16,5 mmHg e 11,6 mmHg, respectivamente, com o treinamento aeróbio. A cinética hipotensiva da PAS apresentou reduções significativas até a 20ª sessão em ambos os grupos. Observou-se estabilização da PAD na 20ª sessão com o treinamento de força e na 10ª sessão com o aeróbio. São necessárias 20 sessões de treinamento de força ou aeróbio para alcance dos benefícios máximos de redução da PA. Os métodos investigados proporcionaram padrões cinéticos adaptativos distintos ao longo das 50 sessões.

to describe the epidemiological clinical profile of tuberculosis and analyze the spatial distribution of cases in a municipality in the state of São Paulo. descriptive and ecological study of cases of tuberculosis through the records in an information system. Descriptive statistics were used to calculate central tendency (mean) and chi-square test, with Yates correction or Fisher exact test, when necessary. The Kernel technique was also used to calculate the occurrence densities of tuberculosis cases, using a radius of 1000 meters. Type I error was set at 5%. 299 cases of tuberculosis were identified, with 290 (96.98%) being geocoded. The majority of these were male (n = 212; 70.91%), median age 40 years, and the pulmonary clinical form was predominant (n = 244, 81.60%). The distribution occurred in a non-random manner, observing important areas of the municipality with a higher density of cases of the disease. the study evidenced an epidemiological profile of tuberculosis cases similar to those in the literature; however, their distribution does not occur in a random manner, pointing to specific population groups that require greater management and planning of health services for the control of tuberculosis. caracterizar o perfil clínico epidemiológico da tuberculose (TB) e analisar a distribuição espacial dos casos em município paulista. estudo descritivo e ecológico dos casos de tuberculose registrados em um sistema de informação.

There are concerns that Reduced Emissions from Deforestation and forest Degradation (REDD+) may fail to deliver potential biodiversity cobenefits if it is focused on high carbon areas. We explored the spatial overlaps between carbon stocks, biodiversity, projected deforestation threats, and the location of REDD+ projects in Indonesia, a tropical country at the forefront of REDD+ development. For biodiversity, we assembled data on the distribution of terrestrial vertebrates (ranges of amphibians, mammals, birds, reptiles) and plants (species distribution models for 8 families). We then investigated congruence between different measures of biodiversity richness and carbon stocks at the national and subnational scales. Finally, we mapped active REDD+ projects and investigated the carbon density and potential biodiversity richness and modeled deforestation pressures within these forests relative to protected areas and unprotected forests. There was little internal overlap among the different hotspots (richest 10% of cells) of species richness. There was also no consistent spatial congruence between carbon stocks and the biodiversity measures: a weak negative correlation at the national scale masked highly variable and nonlinear relationships island by island. Current REDD+ projects were preferentially located in areas with higher total species richness and threatened species richness but lower carbon densities than protected areas and unprotected forests. Although a quarter of the total area of these REDD+ projects is under relatively high deforestation pressure, the majority of the REDD+ area is not. In Indonesia at least, first-generation REDD+ projects are located where they are likely to deliver biodiversity benefits. However, if REDD+ is to deliver additional gains for climate and biodiversity, projects will need to focus on forests with the highest threat to deforestation, which will have cost implications for future REDD+ implementation. Los Patrones Espaciales del Carbono, la Biodiversidad, la Amenaza de Deforestación y los Proyectos REDD+ en Indonesia Resumen Actualmente hay preocupación por que las Emisiones Reducidas de la Deforestación y Degradación del Bosque (REDD+, en inglés) puedan fallar en la entrega de co–beneficios potenciales de la biodiversidad si se enfocan en áreas de alto carbono. Exploramos los traslapes espaciales entre los stocks de carbono, la biodiversidad, las amenazas proyectadas de deforestación y la ubicación de proyectos REDD+ en Indonesia, un país tropical a la vanguardia del desarrollo REDD+. Para la biodiversidad, reunimos datos sobre la distribución de vertebrados terrestres (hábitats de anfibios, mamíferos, aves y reptiles) y plantas (modelos de distribución de especies para ocho familia). Después investigamos la congruencia entre las diferentes medidas de la riqueza de la biodiversidad y los stocks de carbono en la escala nacional y sub–nacional. Finalmente mapeamos proyectos REDD+ activos e investigamos la densidad de carbono y la riqueza potencial de la biodiversidad y modelamos presiones de deforestación dentro de estos bosques en relación con áreas protegidas y no protegidas. Hubo poco traslape interno entre los diferentes hotspots (el 10% más rico de las celdas) de riqueza de especies. Tampoco hubo congruencia espacial consecuente entre los stocks de carbono y las medidas de la biodiversidad: una correlación negativa débil en la escala nacional enmascaró las relaciones altamente variables y no-lineales isla por isla. Los proyectos REDD+ actuales estuvieron ubicados preferencialmente en áreas con una riqueza total de especies y con una riqueza de especies amenazadas más altas pero con densidades de carbono más bajas que en las áreas protegidas y los bosques sin protección. Aunque un cuarto del área total de estos proyectos REDD+ está bajo una presión de deforestación relativamente alta, la mayoría del área REDD+ no lo está. Por lo menos en Indonesia, los proyectos REDD+ de primera generación están ubicados en donde tengan probabilidad de entregar beneficios para la biodiversidad. Sin embargo, si se espera que REDD+ entregue beneficios adicionales para el clima y la biodiversidad, los proyectos necesitarán enfocarse en los bosques con la mayor amenaza de deforestación, lo que tendrá implicaciones de costo para la implementación futura de REDD+.

To determine the level of agreement with effective tobacco control measures recommended by the World Health Organization and to assess the attitudes toward, knowledge of, and beliefs regarding smoking among third-year medical students at University of São Paulo School of Medicine, located in the city of São Paulo, Brazil. Between 2008 and 2012, all third-year medical students were invited to complete a self-administered questionnaire based on the Global Health Professionals Student Survey and its additional modules. The study sample comprised 556 students. The level of agreement with the World Health Organization recommendations was high, except for the components "received smoking cessation training" and "raising taxes is effective to reduce the prevalence of smoking". Most of the students reported that they agree with banning tobacco product sales to minors (95%), believe that physicians are role models to their patients (84%), and believe that they should advise their patients to quit cigarette smoking (96%) and using other tobacco products (94%). Regarding smoking cessation methods, most of the students were found to know more about nicotine replacement therapy than about non-nicotine therapies (93% vs. 53%). Only 37% of the respondents were aware of the importance of educational antismoking materials, and only 31% reported that they believe in the effectiveness of encouraging their patients, during medical visits. In our sample, the prevalence of current cigarette smoking was 5.23%; however, 43.82% of the respondents reported having experimented with water-pipe tobacco smoking. Our results revealed the need to emphasize to third-year medical students the importance of raising the prices of and taxes on tobacco products. We also need to make students aware of the dangers of experimenting with tobacco products other than cigarettes, particularly water-pipe tobacco smoking.

Entre 2008 e 2012, todos os alunos do terceiro ano de medicina foram convidados a preencher um questionário autoaplicável baseado na Global Health Professions Student Survey e em seus módulos adicionais. A amostra consistiu em 556 estudantes. O grau de concordância com as recomendações da Organização Mundial da Saúde foi alto, à exceção de "receberam treinamento a respeito de cessação do tabagismo" e "aumentar os impostos é uma medida eficaz para reduzir a prevalência do tabagismo". A maioria dos estudantes relatou que concorda com a proibição da venda de produtos do tabaco a menores de idade (95%), acredita que os médicos são modelos de comportamento para seus pacientes (84%) e acredita que deveriam aconselhar seus pacientes a parar de fumar cigarros (96%) e de usar outros produtos do tabaco (94%). No tocante aos métodos de cessação do tabagismo, observamos que a maioria dos estudantes sabe mais sobre terapia de reposição da nicotina do que sobre terapias não nicotínicas (93% vs. 53%). Apenas 37% dos participantes estavam cientes da importância de material educacional antitabagismo, e apenas 31% relataram que acreditam na eficácia de incentivar seus pacientes, durante as consultas médicas, a parar de fumar. Em nossa amostra, a prevalência de tabagismo atual foi de 5,23%; entretanto, 43,82% dos participantes relataram ter experimentado fumar tabaco com um narguilé. Nossos resultados revelaram a necessidade de deixar claro para os alunos do terceiro ano de medicina o quão importante é aumentar os preços e impostos dos produtos do tabaco. É também preciso conscientizar os alunos dos perigos de experimentar outros produtos do tabaco que não os cigarros, particularmente o narguilé.

2016-01-01

Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches. The literature was reviewed using the Medline/PubMed, Cochrane library and SciELO databases, and additional information from institutional websites of interest, by cross-correlating the following keywords: acute severe colitis, fulminating colitis and treatment. Treatments for acute severe colitis have avoided colectomy in 60-70% of the cases, provided that they have been started early on, with multidisciplinary follow-up. Despite the adverse effects of intravenous cyclosporine, this drug has been indicated in cases of greater severity with an imminent risk of colectomy, because of its fast action, short half-life and absence of increased risk of surgical complications. Therapy using infliximab has been reserved for less severe cases and those in which immunosuppressants are being or have been used (AZA/6-MP). Indication of biological agents has recently been favored because of their ease of therapeutic use, their good short and medium-term results, the possibility of maintenance therapy and also their action as a "bridge" for immunosuppressant action (AZA/6-MP). Colectomy has been reserved for cases in which there is still no response five to seven days after rescue therapy and in cases of complications (toxic megacolon, profuse hemorrhage and perforation). Patients with a good response to rescue therapy who do not undergo emergency operations should be considered for maintenance therapy using azathioprine. A surgical procedure is indicated for selected cases. A colite aguda grave é emergência médica, potencialmente letal e o seu tratamento permanece ainda nos dias de hoje um desafio para o clínico e cirurgião. A corticoterapia intravenosa introduzida no arsenal terapêutico na década de 50 permanece como primeira linha de tratamento, e nos pacientes refratários a tal medida, a terapia de resgate pode ser com medidas clínicas ou colectomia de urgência. Avaliar os resultados da terapia de resgate medicamentosa (ciclosporina, infliximabe e tracolimus), suas indicações e resultados, e sugerir um guia prático para abordagem clínica. Foi realizada revisão na literatura utilizando as bases Medline/Pubmed, Cochrane Library, Scielo, e informações adicionais em sites institucionais de interesse cruzando os descritores: colite aguda grave, colite fulminante e tratamento. O tratamento da colite aguda grave tem evitado a colectomia em 60- 70% dos casos, desde que iniciado precocemente e com acompanhamento multidisciplinar. A ciclosporina intravenosa apesar de seus efeitos adversos, tem sido indicada naqueles casos mais graves com risco iminente de colectomia, pela sua rapidez de ação, meia-vida curta, e não aumentar os riscos de complicações cirúrgicas. A terapia com infliximabe tem sido reservada para os casos menos graves e naqueles em uso ou já expostos a imunossupressores (AZA/6-MP). A facilidade terapêutica, seus bons resultados a curto e médio prazo, a possibilidade de terapia de manutenção e também por agir como "ponte" para ação de imunossupressores (AZA/6-MP) tem recentemente favorecido a indicação de biológicos. A colectomia fica reservada para casos que não apresentaram resposta a terapia de resgate após cinco a sete dias de tratamento e nas complicações (megacólon tóxico, hemorragia profusa e perfuração). s: Os pacientes com boa resposta à terapia de resgate e não submetidos à operações de urgência, deverão ser considerados para terapia de manutenção com azatioprina, sendo procedimento cirúrgico indicado para casos selecionados.

Low back pain (LBP) is little explored in the aging population especially when considering age-relevant and culturally dependent outcomes. We aimed to describe socio-demographic and clinical characteristics of Brazilian older people with a new episode of LBP presenting to primary care. We sourced baseline information on socio-demographic, pain-related and clinical characteristics from 602 older adults from the Brazilian Back Complaints in the Elders (Brazilian BACE) study. We analyzed differences in pain, disability, functional capacity and psychosocial factors between sub-groups based on age (i.e. participants aged 55-74 or ≥75 years), education (i.e. those with four years or less of schooling or those with more than four years of schooling) and income (i.e. participants who reported earning two or less minimal wages or three and more). Participants presented severe LBP (7.18/10, SD: 2.59). Younger participants were slightly more disabled (mean difference 1.29 points, 95% confidence interval [CI]: 0.03/5.56), reporting poorer physical health, and less fall-related self-efficacy (mean difference of 2.41, 95% CI 0.35/4.46). Those less educated, and those with income equal or less than two minimum wages had more disability, pain catastrophizing and worse functional capacity. This was the first study showing that Brazilian older adults with LBP present high levels of functional disability and psychological distress, especially those with low socioeconomic status.

Souza, Daniel C; Wegner, Fernando; Costa, Lucíola C M; Chiavegato, Luciana D; Lunardi, Adriana C

To test the measurement properties (reproducibility, internal consistency, ceiling and floor effects, and construct validity) of the Human Activity Profile (HAP) questionnaire in hospitalized patients. This measurement properties study recruited one-hundred patients hospitalized for less than 48h for clinical or surgical reasons. The HAP was administered at baseline and after 48h in a test-retest design). The International Physical Activity Questionnaire (IPAQ-6) was also administered at baseline, aiming to assess the construct validity. We tested the following measurement properties: reproducibility (reliability assessed by type 2,1 intraclass correlation coefficient (ICC 2,1 )); agreement by the standard error of measurement (SEM) and by the minimum detectable change with 90% confidence (MDC 90 ), internal consistency by Cronbach's alpha, construct validity using a chi-square test, and ceiling and floor effects by calculating the proportion of patients who achieved the minimum or maximum scores. Reliability was excellent with an ICC of 0.99 (95% CI=0.98-0.99). SEM was 1.44 points (1.5% of the total score), the MDD 90 was 3.34 points (3.5% of the total score) and the Cronbach's alpha was 0.93 (alpha if item deleted ranging from 0.94 to 0.94). An association was observed between patients classified by HAP and by IPAQ-6 (χ 2 =3.38; p=0.18). Ceiling or floor effects were not observed. The HAP shows adequate measurement properties for the assessment of the physical activity/inactivity level in hospitalized patients.

Musculoskeletal disorders are prevalent and represent the most common health problem among the working population in industrially-developing countries, with considerable costs and impact on quality of life. Despite the high incidence of disability insurance claims among Brazilian manufacturing-sector workers, only a few studies assessed musculoskeletal disorders prevalence. To provide information on the prevalence of musculoskeletal disorders among manufacturing-sector workers and to explore the relationship between musculoskeletal disorders and sociodemographic and occupational characteristics in a medium metallurgical company located in Brazil. A cross-sectional study was carried out. Data was collected through the use of a specifically-designed questionnaire and the items used to collect musculoskeletal disorders data were based on the Nordic Musculoskeletal Questionnaire. Descriptive statistics were used and multivariate logistic regression analysis (p<0.02) was performed to explore the associations between musculoskeletal disorders and potential risk factors. The upper limb was the most frequently affected body region among manufacturing-sector workers: shoulder (24.8%), elbow and/or forearm (15.5%), wrist and/or hand (19.0%). Adjusted logistic regression analysis showed that company experience (p=0.02), presence of sleep disorders (p=0.00), self-reported general health state (p=0.00) and perform work pause (p=0.00) were significant risk factors for development of musculoskeletal disorders. Sociodemographic and work-related aspects are influential risk factors for musculoskeletal disorders. These results add comprehension about musculoskeletal disorders prevalence and suggest a need for greater emphasis on prevention strategies.

ABSTRACT OBJECTIVE To evaluate indicators related to the rational use of medicines and its associated factors in Basic Health Units. METHOD This is a cross-sectional study carried out in a representative sample of Brazilian cities included in the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). The data were collected by interviews with users, medicine dispensing professionals, and prescribers; and described by prescription, dispensing, and health services indicators. We analyzed the association between human resources characteristics of pharmaceutical services and dispensing indicators. RESULTS At national level, the average number of medicines prescribed was 2.4. Among the users, 5.8% had antibiotic prescription, 74.8% received guidance on how to use the medicines at the pharmacy and, for 45.1% of users, all prescribed medicines were from the national list of essential medicines. All the indicators presented statistically significant differences between the regions of Brazil. The dispensing professionals that reported the presence of a pharmacist in the unit with a working load of 40 hours or more per week presented 1.82 more chance of transmitting information on the way of using the medicines in the dispensing process. CONCLUSION The analysis of prescription, dispensing, and health services indicators in the basic health units showed an unsatisfactory proportion of essential medicines prescription and limitations in the correct identification of the medicine, orientation to the patients on medicines, and availability of therapeutic protocols in the health services.

ABSTRACT OBJECTIVE To characterize the polypharmacy in primary health care patients and to identify its associated factors. METHODS This is a cross-sectional, exploratory, and evaluative study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). The variable of interest was polypharmacy, defined as the use of five or more medicines. We sought to identify the association of sociodemographic variables and indicators of health conditions to polypharmacy. For group comparison, the Pearson’s Chi-square test was used. The association between polypharmacy and explanatory variables was evaluated by logistic regression model (p < 0.05). The quality of the adjustment was verified by Hosmer-Lemeshow test. RESULTS The prevalence of polypharmacy among medicine users was 9.4% (95%CI 7.8–12.0) in the general population and 18.1% (95%CI 13.6–22.8) in older adults above 65 years old. We found statistically significant association between polypharmacy and age above 45 years, lower self-perception of health, presence of chronic diseases, having health insurance, care in emergency services, and region of the Country. South users presented the highest chances to polypharmacy. The most used medicines were those of the cardiovascular system, being compatible with the national epidemiological profile. CONCLUSIONS Polypharmacy is a reality in the population met within the primary care of Brazilian Unified Health System and may be related to excessive or inappropriate use of medicines. The main challenge to qualify health care is to ensure that prescription of multiple medicines be appropriate and safe. PMID:29160460

ABSTRACT OBJECTIVE To identify limiting factors in the management of pharmaceutical services in the primary health care provided by the Brazilian Unified Health System (SUS). METHODS This study was based on the data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), and it was conducted by interviews with professionals responsible for pharmaceutical services in Brazilian cities, in 2015. To identify the management limiting factors, we considered the organizational, operational, and sustainability indicators of the management. For the analyses, we included the weights and structure of analysis plan for complex samples. The results were expressed by frequencies and measures of central tendency with 95% confidence interval, considering the Brazilian geographic regions. RESULTS We identified the following limiting factors: lack of pharmaceutical services in the Municipal Health Secretariat organization chart (24%) and in the health plan (18%); lack of participation of managers in the Health Board and the absence of reference to this topic in the agenda of meetings (58.4%); lack of financial autonomy (61.5%) and lack of knowledge on the available values (81.7%); lack of adoption of operational procedures (about 50%) for selection, scheduling, and acquisition; and the fact that most professionals evaluate the organization of pharmaceutical services as good and great (58.8%), despite the worrisome indicators. CONCLUSIONS Pharmaceutical services management is currently supported by a legal and political framework that should guide and contribute to improve the pharmaceutical services in the Brazilian Unified Health System primary health care. However, there is a mismatch between the goals established by these guidelines and what is actually happening. PMID:29160449

ABSTRACT OBJECTIVE To analyze the Health-Related Quality of Life (HRQoL) of patients of the primary health care of the Brazilian Unified Health System (SUS) and its associated factors. METHODS This is a cross-sectional study with data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Data were collected with a questionnaire that included the EuroQol 5 Dimensions (EQ-5D) instrument. Patients from the five regions of Brazil were interviewed. Multiple linear regression was used to analyze their Health-Related Quality of Life and its associated factors. RESULTS Of the total of 8,590 patients, the most frequent dimensions were pain/discomfort (50.7%) and anxiety/depression (38.8%). About 10% of the patients reported extreme problems in these dimensions. The following factors were significantly associated with a worse quality of life: being female; having arthritis, osteoarthritis, or rheumatism; cerebrovascular accident; heart disease; depression; health self-assessment as poor or very poor; drinking alcoholic beverages once or more per month; dieting to lose weight, avoiding salt consumption, and reducing fat intake. Significant association was observed between a better quality of life and: living in the North and Southeast regions of Brazil; practicing physical activities; and having a higher educational level. No association was observed with factors related to the health services. CONCLUSIONS The Health-Related Quality of Life of patients was influenced by demographic and socioeconomic factors that were related to health conditions and lifestyle, being useful to guide specific actions for promoting health and the integral care to patients of the Brazilian Unified Health System.

Stroke may lead to several health problems, but positive effects can be promoted by learning to perform physical therapy techniques correctly. To compare two different types of observational practice (video instructions and demonstration by a physical therapist) during the use of incentive spirometry (IS). A total of 20 patients with diagnosis of stroke and 20 healthy individuals (56±9.7 years) were allocated into two groups: one with observational practice with video instructions for the use of IS and the other with observational practice with demonstration by a physical therapist. Ten attempts for the correct use of IS were carried out and the number of errors and the magnitude of response were evaluated. The statistic used to compare the results was the three-way ANOVA test. The stroke subjects showed less precision when compared to the healthy individuals (mean difference 1.80±0.38) 95%CI [1.02-2.52], p<0.0001. When the type of practice was analyzed, the stroke subjects showed more errors with the video instructions (mean difference 1.5±0.5, 95%CI [0.43-2.56] (p=0.08)) and therapist demonstration (mean difference 2.40±0.52, 95%CI [1.29-3.50] (p=0.00)) when compared to the healthy individuals. The stroke subjects had a worse performance in learning the use of volume-oriented incentive spirometry when compared to healthy individuals; however, there was no difference between the types of observational practice, suggesting that both may be used to encourage the use of learning IS in patients with stroke.

1995-03-01

The objective of this study was to assess five cacao cultivars (selfs) and 20 hybrids with regard to their general-and specific-combining ability for yield components using method 1, model I, of the diallel analysis system. The selfings and the hybrids were obtained through controlled crossings, tested in the field in a random block design with four replications and plots containing 16 plants. The experiment was set up in the Centro de Pesquisas do Cacau, in Itabuna, Bahia, Brasil, in 1975. The characteristics studied were: the number of healthy and collected fruits per plant (NHFP and NCFP), the weight of humid seeds per plant and per fruit (WHSP and WHSF), and the percentage of diseased fruits per plant (PDFP), for 5 years (1986-1990). The F-test values, highly significant for general combining ability (GCA) and specific combining ability (SCA), demonstrated the existence of variability for both effects. However, the effects of SCA were greater than those of GCA, when compared in terms of the average squared effects. This condition held for the characteristics NHFP, NCFP and WHSP, which shows the relative importance of the non-additive genetic effects over the additive effects. The reciprocal effects did not show significance. Breeding methods which explore the additive portion of genetic variance should be employed for obtaining higher-yielding cacao and high seed weight. For this, the segregant populations should involve cultivars CEPEC 1, SIAL 169 and ICS 1. Combinations involving the cultivar ICS 1 presented the most favorable results for the characteristics WHSP and WHSF, where the hybrid SIAL 169 x ICS 1 and its reciprocal were outstanding.

OBJECTIVE To evaluate the physical inactivity-related inpatient costs of chronic non-communicable diseases. METHODS This study used data from 2013, from Brazilian Unified Health System, regarding inpatient numbers and costs due to malignant colon and breast neoplasms, cerebrovascular diseases, ischemic heart diseases, hypertension, diabetes, and osteoporosis. In order to calculate the share physical inactivity represents in that, the physical inactivity-related risks, which apply to each disease, were considered, and physical inactivity prevalence during leisure activities was obtained from Pesquisa Nacional por Amostra de Domicílio (Brazil’s National Household Sample Survey). The analysis was stratified by genders and residing country regions of subjects who were 40 years or older. The physical inactivity-related hospitalization cost regarding each cause was multiplied by the respective share it regarded to. RESULTS In 2013, 974,641 patients were admitted due to seven different causes in Brazil, which represented a high cost. South region was found to have the highest patient admission rate in most studied causes. The highest prevalences for physical inactivity were observed in North and Northeast regions. The highest inactivity-related share in men was found for osteoporosis in all regions (≈ 35.0%), whereas diabetes was found to have a higher share regarding inactivity in women (33.0% to 37.0% variation in the regions). Ischemic heart diseases accounted for the highest total costs that could be linked to physical inactivity in all regions and for both genders, being followed by cerebrovascular diseases. Approximately 15.0% of inpatient costs from Brazilian Unified Health System were connected to physical inactivity. CONCLUSIONS Physical inactivity significantly impacts the number of patient admissions due to the evaluated causes and through their resulting costs, with different genders and country regions representing different shares.

To investigate child growth, cognitive/language development, and their environmental and biological determinants. This was a cross-sectional, predictive correlation study with all 92 children aged 24-36 months who attended the municipal early childhood education network in a town in the Vale do Jequitinhonha region, in 2011. The socioeconomic profile was determined using the questionnaire of the Associação Brasileira de Empresas de Pesquisa. The socio-demographicand maternal and child health profiles were created through a self-prepared questionnaire. The height-for-age indicator was selected to represent growth. Cognitive/language development was assessed through the Bayley Scale of Infant and Toddler Development. The quality of educational environments was assessed by Infant/Toddler Environment Scale; the home environment was assessed by the Home Observation for Measurement of the Environment. The neighborhood quality was determined by a self-prepared questionnaire. A multivariate linear regression analysis was performed. Families were predominantly from socioeconomic class D, with low parental education. The prevalence of stunted growth was 14.1%; cognitive and language development were below average at 28.6% and 28.3%, respectively. Educational institutions were classified as inadequate, and 69.6% of homes were classified as presenting a risk for development. Factors such as access to parks and pharmacies and perceived security received the worst score regarding neighborhood environment. Biological variables showed a greater association with growth and environmental variables with development. The results showed a high prevalence of stunting and below-average results for cognitive/language development among the participating children. Both environmental and biological factors were related to growth and development. However, biological variables showed a greater association with growth, whereas environmental variables were associated with development. Copyright © 2015 Sociedade Brasileira de Pediatria.

Neiva, Patricia Dayrell; Kirkwood, Renata Noce; Mendes, Polyana Leite; Zabjek, Karl; Becker, Helena Gonçalves; Mathur, Sunita

Mouth breathing syndrome can cause sleep disturbances that compromise the performance of children in school. It might also cause postural abnormalities involving the head and cervical spine; however, the association between postural abnormalities and mouth breathing in children is unclear. To assess the methodological quality of studies and determine if there is an association between mouth breathing and postural disorders in children. Databases comprised MEDLINE, CINAHL, PEDro, LILACS, EMBASE and Cochrane Central Registrar of Controlled Trials. Searches were until March 2016 and included studies that evaluated postural disorders in children diagnosed with mouth breathing. The Downs and Black checklist was used to evaluate the quality of the evidences. Ten studies were included totaling 417 children from 5 to 14 years. Two studies used the New York State Postural Rating Scale, seven used photography and one used motion capture to measure posture. The methods used to analyze the data included the Postural Analysis Software (SAPO), Fisiometer, ALCimagem and routines in MATLAB program. Quality assessment resulted in low scores (<14) for all the studies. The main areas of weakness were a clear description of the participants, of the methods used to access posture, of the principal confounders and lack of power analysis. External and internal validity were also threatened by the lack of a representative sample and blinding of the participants and assessors, respectively. The review provides low evidence that mouth-breathing pattern in children between the ages 5-14 years is associated with postural deviations.

To identify limiting factors in the management of pharmaceutical services in the primary health care provided by the Brazilian Unified Health System (SUS). This study was based on the data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), and it was conducted by interviews with professionals responsible for pharmaceutical services in Brazilian cities, in 2015. To identify the management limiting factors, we considered the organizational, operational, and sustainability indicators of the management. For the analyses, we included the weights and structure of analysis plan for complex samples. The results were expressed by frequencies and measures of central tendency with 95% confidence interval, considering the Brazilian geographic regions. We identified the following limiting factors: lack of pharmaceutical services in the Municipal Health Secretariat organization chart (24%) and in the health plan (18%); lack of participation of managers in the Health Board and the absence of reference to this topic in the agenda of meetings (58.4%); lack of financial autonomy (61.5%) and lack of knowledge on the available values (81.7%); lack of adoption of operational procedures (about 50%) for selection, scheduling, and acquisition; and the fact that most professionals evaluate the organization of pharmaceutical services as good and great (58.8%), despite the worrisome indicators. Pharmaceutical services management is currently supported by a legal and political framework that should guide and contribute to improve the pharmaceutical services in the Brazilian Unified Health System primary health care. However, there is a mismatch between the goals established by these guidelines and what is actually happening.

We explore potentials that break time-reversal symmetry to confine the surface states of 3D topological insulators into quantum wires and quantum dots. A magnetic domain wall on a ferromagnet insulator cap layer provides interfacial states predicted to show the quantum anomalous Hall effect. Here, we show that confinement can also occur at magnetic domain heterostructures, with states extended in the inner domain, as well as interfacial QAHE states at the surrounding domain walls. The proposed geometry allows the isolation of the wire and dot from spurious circumventing surface states. For the quantum dots, we find that highly spin-polarized quantized QAHE states at the dot edge constitute a promising candidate for quantum computing qubits. See [Ferreira and Loss, Phys. Rev.

Herazo-Beltrán, Yaneth; Pinillos, Yisel; Vidarte, José; Crissien, Estela; Suarez, Damaris; García, Rafael

The perception of personal barriers to physical activity varies according to the sociodemographic characteristics of individuals. To determine the predictors of the perception of barriers to physical activity in the adult population. A cross-sectional study with 1066 adult women and 1036 adult men. The sociodemographic variables (age, gender, marital status, socioeconomic level, level of education), the perception of barriers that do not allow performance of physical activity (i.e. lack of time, social support, energy, motivation, skill, resources, and fear of injury during practice); and the level of physical activity through the International Physical Activity Questionnaire in its short-form version were evaluated. Individuals from low socioeconomic level (1 and 2) have higher risks of perceiving barriers such as lack of motivation [OR 1.76 (95% CI (1.4-2.1))] and lack of resources [OR 1.37 (95% CI (1.1-1.6))]; individuals with partners did not perceive the lack of social support [OR 0.29 (95% CI (0.2-0.4))] and lack of motivation [OR 0.54 (95% CI (0.4-0.7))] as barriers to physical activity. Individuals with low schooling perceived lack of social support [OR 3.81 (95% CI (3-4.7))], lack of resources [OR 2.78 (95% CI (2.2-3.3))], and fear of injury [OR 2.70 (95% CI (2.2-3.3))] as barrier to physical activity. Factors such as socioeconomic level, marital status, level of education, and self-perception of health are predictors of barriers to physical activity.

To understand the life experience of homeless women. A social phenomenological study was conducted with 10 women assisted by a shelter. The analysis of the interviews was based on the theoretical framework of social phenomenology of Alfred Schütz and thematic literature. The participants face adversities in the street context, with emphasis on the risk of physical and sexual abuse, and seek shelters as a possibility for minimizing difficulties experienced. They hope to leave the streets; however, they see themselves trapped in this social reality, due to the addiction to alcohol and other drugs. The understanding of the life experience of homeless women shows daily confrontations and reveals the conflict between the desire for leaving and remaining on the streets, given the complexity of the reality that keeps them in this condition. Compreender a vivência de mulheres em situação de rua. Pesquisa fenomenológica social realizada com 10 mulheres assistidas por um albergue. A análise das entrevistas ancorou-se no referencial teórico da fenomenologia social de Alfred Schütz e literatura temática. As participantes enfrentam adversidades no contexto da rua, com destaque para o risco de violência física e sexual, e buscam o albergue como possibilidade de minimizar as dificuldades vivenciadas. Elas têm como expectativa sair da rua, porém se veem presas a esta realidade social em virtude do vício em álcool e outras drogas. A compreensão da vivência de mulheres em situação de rua aponta enfrentamentos cotidianos e revela o conflito entre o desejo de sair e permanecer na rua, dada a complexidade da realidade que as mantém nesta condição.

To estimate total polyphenol availability in fruits and vegetables commonly consumed in Brazil and its regions, and to identify the main food sources that constitute food habits in this country. Total polyphenols were determined by the Folin-Ciocalteu method and the availability estimated according to the Pesquisa de Orçamentos Familiares 2002/ 2003 (2002/2003 Family Budget Survey). Twelve highly consumed food items were chosen, of which six were 'tropical fruits' and six were vegetables under the categories of 'leafy and flower vegetables', 'fruit vegetables' and 'tuberous vegetables'. Polyphenol quantification was performed with three independent experiments, each one in duplicate. The national polyphenol availability was estimated in grams per fresh weight of each analyzed food. Daily per capita availability in Brazil and its regions was calculated using the amount of polyphenol provided by the consumption of the 12 foods analyzed. Polyphenol contents of foods varied from 15.35 to 214.84 mg GAE/ 100 g of fresh weight. Polyphenol availability in Brazil, based on the amount in kilograms that is annually acquired in Brazil, of the 12 selected foods was 48.3 mg/ day, and the Southeast and Central-West regions had the highest and lowest values, respectively. Banana was the main polyphenol source consumed in Brazil, even though this pattern varied among regions. The estimated daily polyphenol availability in Brazil was similar to other countries. Differences observed among regions could be directly related to distinct cultural habits. Although there is no recommended daily availability of polyphenols, consumption of the recommended daily amount of fruits and vegetables can increase the availability of polyphenols 16 times, showing a clear relationship between the consumption of these food groups and the availability of beneficial bioactive compounds.

The overall purpose of physical therapy for patients with spinal cord injury is to improve health-related quality of life. However, poor adherence is a problem in physical therapy and may have negative impact on outcomes. To explore the physical therapists' perspectives about patients with incomplete post-traumatic paraplegia adherence to recommended home exercises. A qualitative content analysis was conducted. Data were collected in a convenience sample using semi-structured interviews. Thirteen registered physical therapists in Athens area participated in the study. Five categories emerged from the data: (1) reasons to recommend home exercise by the physical therapist; (2) obstacles to recommend home exercise by the physical therapist; (3) methods addressing these obstacles; (4) the family's role in the adherence to recommended home exercise; and (5) the impact of financial crisis in adherence to recommended home exercise. All participants found the recommended home exercises essential to rehabilitation and health maintenance, and they value their benefits. They also expressed the obstacles that need to be faced during rehabilitation process in order to promote adherence. Physical therapists should take into account the different obstacles that may prevent patients with incomplete post-traumatic paraplegia adherence to recommended home exercises. These involve the patients and their families, while, financial crisis has also an impact in adherence. In order to overcome these obstacles and increase adherence, communication with patient and family while taking into account the individual's needs, capacities, and resources are essential.

New Directions in Land Remote Sensing Policy and International Cooperation

NASA Astrophysics Data System (ADS)

Stryker, Timothy

2010-12-01

Recent changes to land remote sensing satellite data policies in Brazil and the United States have led to the phenomenal growth in the delivery of land imagery to users worldwide. These new policies, which provide free and unrestricted access to land remote sensing data over a standard electronic interface, are expected to provide significant benefits to scientific and operational users, and open up new areas of Earth system science research and environmental monitoring. Freely-available data sets from the China-Brazil Earth Resources Satellites (CBERS), the U.S. Landsat satellites, and other satellite missions provide essential information for land surface monitoring, ecosystems management, disaster mitigation, and climate change research. These missions are making important contributions to the goals and objectives of regional and global terrestrial research and monitoring programs. These programs are in turn providing significant support to the goals and objectives of the United Nations Framework Convention on Climate Change (UN FCCC), the Global Earth Observation System of Systems (GEOSS), and the UN Reduction in Emissions from Deforestation and Degradation (REDD) program. These data policies are well-aligned with the "Data Democracy" initiative undertaken by the international Committee on Earth Observation Satellites (CEOS), through its current Chair, Brazil's National Institute for Space Research (Instituto Nacional de Pesquisas Espaciais, or INPE), and its former chairs, South Africa's Council for Scientific and Industrial Research (CSIR) and Thailand's Geo Informatics and Space Technology Development Agency (GISTDA). Comparable policies for land imaging data are under consideration within Europe and Canada. Collectively, these initiatives have the potential to accelerate and improve international mission collaboration, and greatly enhance the access, use, and application of land surface imagery for environmental monitoring and societal adaption to changing climate conditions.

Factor and Rasch analysis of the Fonseca anamnestic index for the diagnosis of myogenous temporomandibular disorder.

PubMed

Rodrigues-Bigaton, Delaine; de Castro, Ester M; Pires, Paulo F

Rasch analysis has been used in recent studies to test the psychometric properties of a questionnaire. The conditions for use of the Rasch model are one-dimensionality (assessed via prior factor analysis) and local independence (the probability of getting a particular item right or wrong should not be conditioned upon success or failure in another). To evaluate the dimensionality and the psychometric properties of the Fonseca anamnestic index (FAI), such as the fit of the data to the model, the degree of difficulty of the items, and the ability to respond in patients with myogenous temporomandibular disorder (TMD). The sample consisted of 94 women with myogenous TMD, diagnosed by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), who answered the FAI. For the factor analysis, we applied the Kaiser-Meyer-Olkin test, Bartlett's sphericity, Spearman's correlation, and the determinant of the correlation matrix. For extraction of the factors/dimensions, an eigenvalue >1.0 was used, followed by oblique oblimin rotation. The Rasch analysis was conducted on the dimension that showed the highest proportion of variance explained. Adequate sample "n" and FAI multidimensionality were observed. Dimension 1 (primary) consisted of items 1, 2, 3, 6, and 7. All items of dimension 1 showed adequate fit to the model, being observed according to the degree of difficulty (from most difficult to easiest), respectively, items 2, 1, 3, 6, and 7. The FAI presented multidimensionality with its main dimension consisting of five reliable items with adequate fit to the composition of its structure.

Sartor, Cristina D; Oliveira, Mariana D; Campos, Victoria; Ferreira, Jane S S P; Sacco, Isabel C N

The Michigan Neuropathy Screening Instrument is an easy-to-use questionnaire aimed at screening and detecting diabetic polyneuropathy. To translate and cross-culturally adapt the MNSI to Brazilian Portuguese and evaluate its measurement properties. Two bilingual translators translated from English into Brazilian Portuguese and made a synthetic version. The synthetic version was back translated into English. A committee of specialists and the translator checked the cultural adaptations and developed a pre-final questionnaire in Brazilian Portuguese (prefinal version). In pretesting, the prefinal version was applied to a sample of 34 subjects in which each subject was interviewed to determine whether they understood each item. For the later assessment of measurement properties, 84 subjects were assessed. A final Brazilian Portuguese version of the instrument was produced after obtaining 80% agreement (SEM<0.01%) among diabetic patients and specialists. We obtained excellent intra-rater reliability (ICC 3,1 =0.90), inter-rater reliability (ICC 2,1 =0.90) and within-subject reliability ICC 3,1 =0.80, excellent internal consistency (Cronbach's alpha>0.92), reasonable construct validity for the association between the MNSI and Neuropathy Symptom Score (r=0.46, p<0.05) and excellent association between the MNSI and Neuropathy Disability Score (r=0.79, p<0.05). We did not detect floor and ceiling effects (<9.5% of patients with maximum scores). The Brazilian Portuguese version of the MNSI is suitable for application in the Brazilian diabetic population and is a reliable tool for the screening and detection of DPN. The MNSI can be used both in clinical practice and also for research purposes. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia. Publicado por Elsevier Editora Ltda.

ABSTRACT OBJECTIVE To characterize the workforce in the pharmaceutical services in the primary care of the Brazilian Unified Health System (SUS). METHODS This is a cross-sectional and quantitative study, with data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). For the analysis, we considered the data stratification into geographical regions. We analyzed the data on workers in the municipal pharmaceutical services management and in the medicine dispensing units, according to the country’s regions. For the statistical association analysis, we carried out a Pearson correlation test for the categorical variables. RESULTS We analyzed 1,175 pharmacies/dispensing units, 507 phone interviews (495 pharmaceutical services coordinators), and 1,139 professionals responsible for medicine delivery. The workforce in pharmaceutical services was mostly constituted by women, aged from 18 to 39 years, with higher education (90.7% in coordination and 45.5% in dispensing units), having permanent employment bonds (public tender), being for more than one year in the position or duty, and with weekly work hours above 30h, working both in municipal management and in medicine dispensing units. We observed regional differences in the workforce composition in dispensing units, with higher percentage of pharmacists in the Southeast and Midwest regions. CONCLUSIONS The professionalization of municipal management posts in primary health care is an achievement in the organization of the workforce in pharmaceutical services. However, significant deficiencies exist in the workforce composition in medicine dispensing units, which may compromise the medicine use quality and its results in population health. PMID:29160455

2008-09-01

Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

The influence of dosing on effect size of exercise therapy for musculoskeletal foot and ankle disorders: a systematic review.

PubMed

Young, Jodi L; Rhon, Daniel I; de Zoete, Rutger M J; Cleland, Joshua A; Snodgrass, Suzanne J

The purpose of this review was to identify doses of exercise therapy associated with greater treatment effect sizes in individuals with common musculoskeletal disorders of the foot and ankle, namely, achilles tendinopathy, ankle sprains and plantar heel pain. AMED, EMBASE and MEDLINE were searched from 2005 to August 2017 for randomized controlled trials related to exercise for these three diagnoses. The Physiotherapy Evidence Database scale was used for methodological quality assessment. Exercise dosing variables and outcome measures related to pain and function were extracted from the studies, and standardized mean differences were calculated for the exercise groups. Fourteen studies met the final inclusion. A majority of the studies showed large effects and two small trends were identified. Patients with plantar heel pain may benefit more from a daily home exercise program than two supervised visits per week (SMD=3.82), but this recommendation is based on weak evidence. In achilles tendinopathy, a relationship was also seen when sets and repetitions of eccentric exercise were performed as tolerated (SMD=1.08 for function, -1.29 for pain). Session duration, frequency, total number of visits, and overall length of care may all be dosing variables with limited value for determining effective exercise prescription. However, the limited number of studies prevents any definitive conclusions. Further investigation is warranted to improve our understanding of the influence exercise dosing has on treatment effect sizes. Future randomized controlled trials comparing specific exercise dose variables should be conducted to clarify the impact of these variables.

Magalhães, Maurício Oliveira; Comachio, Josielli; Ferreira, Paulo Henrique; Pappas, Evangelos; Marques, Amélia Pasqual

Low back pain (LBP) is a major health and economic problem worldwide. Graded activity and physiotherapy are commonly used interventions for nonspecific low back pain. However, there is currently little evidence to support the use of one intervention over the other in the medium-term. To compare the effectiveness of graded activity exercises to physiotherapy-based exercises at mid-term (three and six months' post intervention) in patients with chronic nonspecific LBP. Sixty-six patients were randomly allocated to two groups: graded activity group (n=33) and physiotherapy group (n=33). These patients received individual sessions twice a week for six weeks. Follow-up measurements were taken at three and six months. The main outcome measurements were intensity pain (Pain Numerical Rating Scale) and disability (Rolland Morris Disability Questionnaire). No significant differences between groups after three and six month-follow ups were observed. Both groups showed similar outcomes for pain intensity at three months [between group differences: -0.1 (95% confidence interval [CI]=-1.5 to 1.2)] and six months [0.1 (95% CI=-1.1 to 1.5)], disability at three months was [-0.6 (95% CI=-3.4 to 2.2)] and six months [0.0 (95% CI=-2.9 to 3.0)]. The results of this study suggest that graded activity and physiotherapy have similar effects in the medium-term for patients with chronic nonspecific low back pain.

The six-minute walk test (6MWT) is a simple, low cost, reliable, and valid method for evaluating the functional capacity of cardiac patients. However, its early use and safety following acute myocardial infarction (AMI) is recent and has been little investigated. To evaluate and to compare the safety and the cardiac behavior of early performance of the 6MWT in patients following uncomplicated AMI up to 4 days or more than 4 days after the event. Following discharge from the Coronary Care Unit, 152 stable asymptomatic patients diagnosed with uncomplicated AMI performed the 6MWT. During the test, in addition to the distance walked, heart rate (HR), blood pressure (BP), and adverse events were also recorded. Electrocardiography was recorded using a Holter monitor in 105 patients. Patients were allocated considering two groups according to the number of days since AMI: Up to 4 Days Group and After 4 Days Group. All patients completed the 6MWT, 66 in the Up to 4 Days Group and 86 in the After 4 Days Group. The walking distance was similar in both groups (85% of the predicted value), as well as the physiological responses (increase in systolic BP and HR), reaching 63% (median) of maximum HR. Only 3.9% of patients had major complications (angina, drop in BP, or ventricular tachycardia), with no difference between the groups. None of the complications regarded as severe led to truly significant complications or death. The 6MWT was proven to be safe and feasible for early functional evaluation following uncomplicated AMI.

Em 2002 o ensino de Astronomia foi proposto como um dos temas estruturadores pelos Parâmetros Curriculares Nacionais e sugerido como facilitador para que o aluno compreendesse a Física como construção humana e parte do seu mundo vivencial, mas raramente seus conceitos foram ensinados. A presente pesquisa discute dois aspectos relacionados à abordagem de Astronomia. O primeiro aspecto é se ela está sendo abordada pelos professores do Ensino Médio e o segundo, aborda a maneira como ela está sendo ensinada. Optou-se pela aplicação de um questionário a partir do 2° semestre de 2006 e durante o ano de 2007 com professores que ministram a disciplina de Física, os quais trabalham em escolas estaduais em Rio Grande da Serra, Ribeirão Pires e Mauá no estado São Paulo. Dos 66,2% dos professores que responderam ao questionário nos municípios de Rio Grande da Serra, Ribeirão Pires e Mauá, 57,4% não aplicaram nenhum tópico de astronomia, 70,2% não utilizaram laboratório, 89,4% não utilizaram qualquer tipo de programa computacional, 83,0% nunca fizeram visitas com alunos a museus e planetários e 38,3% não indicaram qualquer tipo de livro ou revista referente à astronomia aos seus alunos. Mesmo considerando a Astronomia um conteúdo potencialmente significativo, esta não fez parte dos planejamentos escolares. Portanto são necessárias propostas que visem estratégias para a educação continuada dos professores como, por exemplo, cursos específicos sobre o ensino em Astronomia.

To evaluate the physical inactivity-related inpatient costs of chronic non-communicable diseases. This study used data from 2013, from Brazilian Unified Health System, regarding inpatient numbers and costs due to malignant colon and breast neoplasms, cerebrovascular diseases, ischemic heart diseases, hypertension, diabetes, and osteoporosis. In order to calculate the share physical inactivity represents in that, the physical inactivity-related risks, which apply to each disease, were considered, and physical inactivity prevalence during leisure activities was obtained from Pesquisa Nacional por Amostra de Domicílio(Brazil's National Household Sample Survey). The analysis was stratified by genders and residing country regions of subjects who were 40 years or older. The physical inactivity-related hospitalization cost regarding each cause was multiplied by the respective share it regarded to. In 2013, 974,641 patients were admitted due to seven different causes in Brazil, which represented a high cost. South region was found to have the highest patient admission rate in most studied causes. The highest prevalences for physical inactivity were observed in North and Northeast regions. The highest inactivity-related share in men was found for osteoporosis in all regions (≈ 35.0%), whereas diabetes was found to have a higher share regarding inactivity in women (33.0% to 37.0% variation in the regions). Ischemic heart diseases accounted for the highest total costs that could be linked to physical inactivity in all regions and for both genders, being followed by cerebrovascular diseases. Approximately 15.0% of inpatient costs from Brazilian Unified Health System were connected to physical inactivity. Physical inactivity significantly impacts the number of patient admissions due to the evaluated causes and through their resulting costs, with different genders and country regions representing different shares.

Strategies adopted by younger and older adults while operating a non-pedal tricycle.

PubMed

Calve, Tatiane; Russo Júnior, Douglas Vicente; Barela, Ana Maria Forti

Exercises that could prevent gait impairment of older adults should be implemented in such a way that practitioners can keep motivation and adherence independent of older adults fitness levels. This study describes how younger and older adults use a non-pedal tricycle to transport their bodies along a pathway. Nine younger (24±4.9y) and nine older (66±4.0y) adults participated in this study. They moved along a straight pathway at a self-selected comfortable speed with reflective markers on their main lower limb landmarks. A computerized gait analysis system with infrared cameras was used to obtain kinematic data to calculate spatial-temporal parameters and lower limb angles. Overall, participants from both groups were able to perform the task moving at a similar mean speed, with similar stride length and ankle joint excursion. Older adults had higher cadence (mean difference of 17steps/min; 95% CI=0.99-1.15) and hip excursion (mean difference of 12°; 95% CI=28-33), longer stance duration (mean difference of 3.4%; 95% CI=56.2-59.5), and lower knee excursion (mean difference of 6°; 95% CI=47.9-53.8) than younger adults. Older adults were able to transport their body with a non-pedal tricycle with more hip and less knee excursion than younger adults. Professionals that work with the older population should look at and take into consideration the use of non-pedal tricycles in exercise protocols and investigate the long-term impacts.

Exercise training to reduce sympathetic nerve activity in heart failure patients. A systematic review and meta-analysis.

PubMed

Saavedra, María Javiera; Romero, Fernando; Roa, Jorge; Rodríguez-Núñez, Iván

To determine the effects of exercise training on sympathetic nerve activity in heart failure patients. A systematic review was performed. An electronic search of MEDLINE, ProQuest, SciELO, SPORTDiscus, Rehabilitation and Sport Medicine Source, Cumulative Index to Nursing and Allied Health Literature, Tripdatabase, Science Direct and PEDrO was performed from their inception to February 2017. Clinical trials and quasi-experimental studies were considered for primary article selection. The studies should include patients diagnosed with chronic heart failure that performed exercise training for at least 4 weeks. Sympathetic nerve activity should be measured by microneurography before and after the intervention. The Cochrane Collaboration's Risk of Bias Tool was used to evaluate risk of bias, and the quality of evidence was rated following the GRADE approach. Standardized mean differences (SMD) were calculated for control and experimental groups. Meta-analysis was performed using the random effects model. Five trials were included. Overall, the trials had moderate risk of bias. The experimental group indicated a significant decrease in the number of bursts per minute (SMD -2.48; 95% CI -3.55 to -1.41) when compared to the control group. Meanwhile, a significant decrease was also observed in the prevalence of bursts per 100 beats in the experimental group when compared to the control group (SMD -2.66; 95% CI -3.64 to -1.69). Exercise training could be effective in reducing sympathetic nerve activity in patients with heart failure. The quality of evidence across the studies was moderate. Future studies are necessary to confirm these results. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia. Publicado por Elsevier Editora Ltda. All rights reserved.

Ischemic stroke (IS) and Chagas disease are strongly related. Nevertheless, little attention has been paid to this association and its natural history. The current guidelines concerning the management and secondary prevention of IS are largely based on the incomplete information or extrapolation of knowledge from other stroke etiologies. We performed a retrospective study which compared stroke etiologies among a cohort of hospitalized patients with IS and Chagas disease. The Instituto de Pesquisa Evandro Chagas/Fundação Oswaldo Cruz (IPEC/FIOCRUZ) embolic score was also used to identify and evaluate the risk of embolism in this population. A total of 86 patients were included in the analysis. The mean age of the study population was 58 years, and 60 % were men. According to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) Classification, 45 % of the strokes were of undetermined etiology and 45 % of cardioembolic origin, while the Stop Stroke Study/Causative Classification System (SSS/CCS) TOAST indicated that 34 % were undetermined and 50 % cardioembolic (p < 0.01); 44 % of these patients were classified as having a high embolic risk according to the IPEC/FIOCRUZ score. Among the undetermined causes, 83.3 % fulfilled the criteria for embolic stroke of undetermined source (ESUS). The SSS/CCS TOAST etiological classification system was superior to the classical TOAST criteria in identifying a cardioembolic etiology in patients with ischemic stroke and Chagas disease. The IPEC/FIOCRUZ score did not correlate with the number of patients who were determined to have cardioembolic stroke etiologies. The current guidelines for stroke prevention should be reviewed in this population.

Currently, there is poor evidence of the effect of hydrotherapy alone on patients with hip or knee osteoarthritis. The study aimed to assess the impact of hydrotherapy on pain, function, and muscle function in older women with knee osteoarthritis. A randomized controlled trial was conducted to evaluate the efficacy of hydrotherapy in women with knee osteoarthritis. Seventy-three women aged 65 and older were randomized to hydrotherapy (n=36) or a control group (n=37). The hydrotherapy group received the intervention program in a heated pool (twice per week for six weeks) and an educational protocol while the control group received an educational protocol only. Primary outcomes (before and post-treatment) were pain intensity (0-100) and function (0-100), assessed with the WOMAC questionnaire. Secondary outcomes (before and post-treatment) were knee extensor and knee flexor muscle performance (strength, power, and endurance), assessed by an isokinetic dynamometer. The magnitude of change between the groups for the outcomes was calculated using linear regression models adjusted by baseline outcome values. The hydrotherapy group had better outcomes for pain (adjusted mean difference=11 points, 95% CI: 3-18) and function (adjusted mean difference=12 points, 95% CI: 5-18). Patients receiving hydrotherapy had better performance for knee flexor and extensor strength, knee flexor power, and knee extensor endurance. Older women with knee osteoarthritis are likely to have benefits from a course of hydrotherapy exercises.

Neck pain is a musculoskeletal condition with high prevalence that may affect the physical, social, and psychological aspects of the individual, contributing to the increase in costs in society and business. To determine the prevalence of neck pain and associated factors in a population-based sample of adults aged 20 and more. Cross-sectional study based on a population survey. A total number of 600 individuals were interviewed in their homes, and the following data were collected: (1) participant characteristics (demographic, socioeconomic, and work-related aspects) using a pre-coded questionnaire; (2) physical activity level using the IPAQ; and (3) musculoskeletal symptoms using the Nordic questionnaire. Descriptive, bivariate, and Poisson regression analyses were performed. The prevalence of neck pain was 20.3% (95% CI 17.3-23.7). The adjusted analyses showed that individuals who were widowers or separated (PR=2.26; 1.42-5.88), had a low income (PR=1.32; 1.22-6.27) or low educational level (PR=1.83; 1.02-5.26), worked while sitting and leaning (PR=1.55; 1.08-2.40), and who reported having two or more diseases (PR=1.71; 1.55-6.31) remained associated with neck pain. This study reveals the high prevalence of neck pain and remarkable association with widowed/separated people who have low income and low educational level, who perform their occupational activities in sitting and leaning positions, and who reported having two or more diseases. Knowledge of these risk factors will contribute to the development of forms of assistance in which neck pain can be prevented and better managed.

The progression through the difficulty levels of Pilates exercises is a subjective criterion, that depends on the therapist's experience and ability to identify the best moment to progress to the next level. To identify the factors that interfere in the progression through the difficulty levels of the Pilates exercises in patients with chronic nonspecific low back pain. Data from 139 patients with chronic nonspecific low back pain from a randomized controlled trial were used for statistical analysis using binary logistic regression. The dependent variable was the progression through the difficulty levels, and the independent variables were age, gender, educational level, low back pain duration, pain intensity, general disability, kinesiophobia, previous physical activity, and number of absences. The factors that interfered in the progression through the difficulty levels were previous physical inactivity (odds ratio [OR]=5.14, 95% confidence interval [CI]: 1.53-17.31), low educational level (OR=2.62, 95% CI: 1.12-6.10), more advanced age (OR=0.95, 95% CI: 0.92-0.98) and more absences (OR=0.63, 95% CI: 0.50-0.79). These variables explain 41% of the non-progression through the difficulty level of the exercises. Physical inactivity, low educational level, more advanced age and greater number of absences can be interfering factors in the progression through the difficulty levels of the Pilates exercises in patients with chronic nonspecific low back pain.

Junior, Jefferson F C R; Silva, Alexandre S; Cardoso, Glêbia A; Silvino, Valmir O; Martins, Maria C C; Santos, Marcos A P

There is evidence of hypertensive effects caused by anabolic androgenic steroids (AAS). A single exercise session promotes the acute reduction of blood pressure, but the effects of AAS on this phenomenon are unknown. To investigate the post-exercise blood pressure response in androgenic-anabolic steroid users. Thirteen AAS users (23.9±4.3 years old) and sixteen controls (22.1±4.5 years old) performed a session of aerobic exercise. Heart rate and blood pressure were assessed before exercise and during a 60min post-exercise resting period. Repeated ANOVA measures were used to determine differences between the groups. While the control group had a significant reduction in post-exercise systolic blood pressure of up to 13.9±11.6mmHg at 40min, this phenomenon was limited among AAS users who reached a maximum of 6.2±11.5mmHg at 60min. The between groups comparison revealed significant higher post-exercise hypotension (PEH) for the control group at 30min (-12.9±14.1mmHg versus -2.9±7.6mmHg), 40min (-13.9±11.6mmHg versus -2.5±8.3mmHg), 50min (-13.9±13.9mmHg versus -5.0±7.9mmHg) and 60min (-12.5±12.8mmHg versus -6.2±11.5mmHg). There was no significant diastolic PEH in any of the groups. This study demonstrated impaired systolic post-exercise hypotension as a new adverse effect of AAS usage.

A investigação do campo de flutuações da Radiação Cósmica de Fundo (RCF) pode oferecer um importante teste para os modelos cosmológicos que descrevem a origem e a evolução das flutuações primordiais. De um lado, apresenta-se o modelo inflacionário que prevê um espectro de flutuações adiabáticas distribuídas segundo uma gaussiana e, de outro, os modelos de defeitos topológicos (dentre outros) que descrevem um mecanismo para a geração de flutuações de isocurvatura que obedecem a uma distribuição não gaussiana. Este trabalho tem como objetivo caracterizar traços do modelo não gaussiano de campo misto (entre flutuações adiabáticas e de isocurvatura) nos mapas do Wilkinson Microwave Anisotropy Probe (WMAP). Simulações das anisotropias da RCF no contexto de mistura indicam traços marcantes na distribuição das flutuações de temperatura, mesmo quando consideradas pequenas contribuições do campo de isocurvatura (da ordem de 0.001). O efeito da mistura entre os campos resulta na transferência de potência de flutuações em escalas angulares intermediárias para flutuações em pequenas escalas angulares. Este efeito pode ser caracterizado pela relação entre as amplitudes dos primeiros picos acústicos no espectro de potência da RCF. Neste trabalho, investigamos a contribuição do campo de isocurvatura, no contexto de mistura, sobre as observações recentes da RCF realizadas pelo WMAP. As previsões do modelo de campo misto, uma vez confrontadas com as observações em pequenas escalas angulares, podem ajudar a revelar a natureza das flutuações primordiais.

Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico.Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal.Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión.Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos.Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

At local scales, infectious disease is a common driver of population declines, but globally it is an infrequent contributor to species extinction and endangerment. For species at risk of extinction from disease important questions remain unanswered, including when does disease become a threat to species and does it co-occur, predictably, with other threats? Using newly compiled data from the International Union for Conservation of Nature (IUCN) Red List, we examined the relative role and co-occurrence of threats associated with amphibians, birds, and mammals at 6 levels of extinction risk (i.e., Red List status categories: least concern, near threatened, vulnerable, endangered, critically endangered, and extinct in the wild/extinct). We tested the null hypothesis that the proportion of species threatened by disease is the same in all 6 Red List status categories. Our approach revealed a new method for determining when disease most frequently threatens species at risk of extinction. The proportion of species threatened by disease varied significantly between IUCN status categories and linearly increased for amphibians, birds, and all species combined as these taxa move from move from least concern to critically endangered. Disease was infrequently the single contributing threat. However, when a species was negatively affected by a major threat other than disease (e.g., invasive species, land-use change) that species was more likely to be simultaneously threatened by disease than species that had no other threats. Potential drivers of these trends include ecological factors, clustering of phylogenetically related species in Red List status categories, discovery bias among species at greater risk of extinction, and availability of data. We echo earlier calls for baseline data on the presence of parasites and pathogens in species when they show the first signs of extinction risk and arguably before.

Introducción La epidemia de VIH y SIDA se ha diseminado rápidamente a nivel mundial tendiendo a la feminización, pauperización y heterosexualización. La comunicación de pareja en torno el VIH es descrita como uno de los factores protectores en la adquisición de esta enfermedad, favoreciendo la adopción de conductas sexuales seguras tales como la negociación de pareja y la utilización de preservativo, consideróndose como un pilar fundamental en la incorporación de medidas de autocuidado en la sexualidad femenina. Objetivo Determinar el nivel de comunicación de pareja en torno al VIH en mujeres chilenas en desventaja social. Metodología Cuatrocientas noventa y seis mujeres contestaron la entrevista inicial de la investigación “Testing an HIV/AIDS Prevention Intervention for Chilean Women” (RO1 TW 006977 PI Cianelli). Se utilizó la escala “Health protective sexual communication scale (HPC)” (0–10 puntos). Se realizó un análisis descriptivo utilizando el programa SPSS 16.0. Resultados El promedio del nivel de comunicación de pareja fue de 3,26 ± 2,7 puntos con la pareja principal, de 2,52 ± 2,48 puntos con una segunda pareja y de 0 puntos con una tercera pareja. Los temas de menor comunicación entre las parejas fueron el uso de preservativo y la realización del test para VIH antes de tener relaciones sexuales. Conclusión Las mujeres de la muestra presentan bajos niveles de comunicación de pareja en relación a VIH con todas sus parejas sexuales. Son necesarias estrategias que potencien este tópico dentro de las intervenciones de prevención de VIH y SIDA de manera de fortalecer la adopción de conductas de autocuidado en torno al tema.

Selección de recetas facturadas de productos NED en el conjunto de la Región, clasificación por tipos y análisis de la evolución en importe y en envases para el periodo 2007-2010.Resultados: respecto al perfil de la muestra del Área I de Salud de la Región, la patología, vía de administración y tipo de nutrición más frecuentes resultaron, respectivamente, la enfermedad neurológica, la vía oral y la nutrición no específica. Por otro lado, el gasto sanitario en productos dietoterápicos, en el Servicio Murciano de Salud, aumentó alrededor del 50% entre los años 2007 y 2010. Tanto en envases como en importe, Murcia se sitúa por encima de la media nacional.Conclusiones: el perfil de la muestra no coincide con trabajos publicados en otras regiones. Este dato, junto a la posición de Murcia en gasto dietoterápico, y su evidente tendencia al alza en los años analizados, hace evidente la necesidad de medidas que mejoren la calidad de la NED en la Región de Murcia y, en caso de ser posible, conseguir alcanzar valores nacionales en relación con el consumo medio y el gasto.

Increase in quantity and quality of suitable areas for invasive species as climate changes.

Bertelsmeier, Cleo; Luque, Gloria M; Courchamp, Franck

2013-12-01

As climatically suitable range projections become increasingly used to assess distributions of species, we recommend systematic assessments of the quality of habitat in addition to the classical binary classification of habitat. We devised a method to assess occurrence probability, captured by a climatic suitability index, through which we could determine variations in the quality of potential habitat. This relative risk assessment circumvents the use of an arbitrary suitability threshold. We illustrated our method with 2 case studies on invasive ant species. We estimated invasion potential of the destroyer ant (Monomorium destructor) and the European fire ant (Myrmica rubra) on a global scale currently and by 2080 with climate change. We found that 21.1% of the world's landmass currently has a suitable climate for the destroyer ant and 16% has a suitable climate for European fire ant. Our climatic suitability index showed that both ant species would benefit from climate change, but in different ways. The size of the potential distribution increased by 35.8% for the destroyer ant. Meanwhile, the total area of potential distribution remained the same for the European fire ant (>0.05%), but the level of climatic suitability within this range increased greatly and led to an improvement in habitat quality (i.e., of invasive species' establishment likelihood). Either through quantity or quality of suitable areas, both invasive ant species are likely to increase the extent of their invasion in the future, following global climate change. Our results show that species may increase their range if either more areas become suitable or if the available areas present improved suitability. Studies in which an arbitrary suitability threshold was used may overlook changes in area quality within climatically suitable areas and as a result reach incorrect predictions.

Rovero, A. C.; Colombo, E.; Sahade, J.; Weekes, T. C.

La astronomía gamma, en el extremo de energías detectadas hasta el presente, se encuentra en desarrollo en muchas partes del mundo y proporciona resultados sorprendentes a medida que la tecnología avanza en el desarrollo de nuevos detectores. La técnica Cherenkov Atmosférica es la utilizada para la detección, mediante telescopios en tierra, del efecto secundario causado por la radiación gamma de muy altas energías (E ≈ TeV). Por medio de telescopios o arreglos de detectores y utilizando la técnica mencionada, se han podido detectar algunas fuentes puntuales de mucha importancia astrofísica como la Nebulosa del Cangrejo y la galaxia de núcleo activo Markarian 421. El sistema instalado en San Juan, en cooperación con el grupo de Radiación Gamma del Observatorio Whipple, está constituído por tres colectores de 1.5m que registran pulsos de luz generados por las cascadas de partículas producidas por rayos cósmicos de todo tipo al entrar en la atmósfera terrestre. El sistema opera por barrido en ascención recta de la fuente observada que, para esta etapa del experimento, es el Centro Galáctico. Esta fuente extensa es conocida como emisor gamma de energías inferiores al TeV y ha sido observada anteriormente en este rango de energía desde el hemisferio norte pero con elevaciones bajas, situación no óptima para este tipo de técnica. Se presentan los primeros resultados del análisis de los datos obtenidos observando la región del Centro Galáctico, luego de dos años de observaciones, así como una descripción de la técnica Cherenkov Atmosférica y del equipo utilizado en la experiencia.

Esta tese apresenta um sistema de localizacao baseado exclusivamente em ultrassons, nao necessitando de recorrer a qualquer outra tecnologia. Este sistema de localizacao foi concebido para poder operar em ambientes onde qualquer outra tecnologia nao pode ser utilizada ou o seu uso esta condicionado, como sao exemplo aplicacoes subaquaticas ou ambientes hospitalares. O sistema de localizacao proposto faz uso de uma rede de farois fixos permitindo que estacoes moveis se localizem. Devido a necessidade de transmissao de dados e medicao de distancias foi desenvolvido um pulso de ultrassons robusto a ecos que permite realizar ambas as tarefas com sucesso. O sistema de localizacao permite que as estacoes moveis se localizem escutando apenas a informacao em pulsos de ultrassons enviados pelos farois usando para tal um algoritmo baseado em diferencas de tempo de chegada. Desta forma a privacidade dos utilizadores e garantida e o sistema torna-se completamente independente do numero de utilizadores. Por forma a facilitar a implementacao da rede de farois apenas sera necessario determinar manualmente a posicao de alguns dos farois, designados por farois ancora. Estes irao permitir que os restantes farois, completamente autonomos, se possam localizar atraves de um algoritmo iterativo de localizacao baseado na minimizacao de uma funcao de custo. Para que este sistema possa funcionar como previsto sera necessario que os farois possam sincronizar os seus relogios e medir a distancia entre eles. Para tal, esta tese propoe um protocolo de sincronizacao de relogio que permite tambem obter as medidas de distancia entre os farois trocando somente tres mensagens de ultrassons. Adicionalmente, o sistema de localizacao permite que farois danificados possam ser substituidos sem comprometer a operabilidade da rede reduzindo a complexidade na manutencao. Para alem do mencionado, foi igualmente implementado um simulador de ultrassons para ambientes fechados, o qual provou ser bastante preciso e uma ferramenta de elevado valor para simular o comportamento do sistema de localizacao sobre condicoes controladas.

Groundwater plays an important role for urban and industrial water supply in northern China. More than 1000 groundwater wellfields have been explored and installed. Groundwater provides about half the total quantity of the urban water supply. Complete regulations and methods for the exploration of groundwater have been established in the P.R. China. Substantial over-exploitation of groundwater has created environmental problems in some cities. Some safeguarding measures for groundwater-resource protection have been undertaken. Résumé Les eaux souterraines jouent un rôle important dans l'approvisionnement en eau des agglomérations et des industries du nord de la Chine. Les explorations ont conduit à mettre en place plus de 1000 champs de puits captant des eaux souterraines. Les eaux souterraines satisfont environ la moitié des besoins en eau des villes. Une réglementation complète et des méthodes d'exploration des eaux souterraines ont étéétablies en République Populaire de Chine. Une surexploitation très nette est à l'origine de problèmes environnementaux dans certaines villes. Des mesures ont été prises pour protéger la ressource en eau souterraine.

Este estudio ausculto las concepciones epistemologicas de los docentes de ciencia del nivel secundario con relacion a las ideologias y las ciencias naturales. Tambien examino las posiciones de los docentes ante asuntos publicos relacionados a la ciencia. Para propositos de este estudio se diseno y se valido el cuestionario con el cual se obtuvieron los resultados. La investigacion es de tipo cuantitativa y se utilizo como diseno la encuesta. El cuestionario se administro en varias actividades de desarrollo profesional para maestros de ciencia. Un total de 78 maestros del nivel secundario respondieron el cuestionario. Para analizar los datos obtenidos se utilizaron estadisticas descriptivas como la distribucion de frecuencia y el porciento. Ademas se establecieron codigos y categorias para describir las posiciones de los maestros ante asuntos publicos relacionados a la ciencia. Los analisis demostraron que entre los docentes participantes de este estudio prevalecen ciertas concepciones epistemologicas adecuadas acerca de las ciencias naturales, a la luz de la literatura consultada. Entre estas concepciones se destacan las siguientes: a) la filosofia materialista de las ciencias naturales, b) la naturaleza tentativa y constructivista del conocimiento cientifico, c) el uso de una metodologia que garantiza cierto grado de objetividad y con el que se justifican y validan los enunciados cientificos y d) la funcion instrumental del conocimiento cientifico. Sin embargo, entre los docentes participantes de este estudio prevalecen ciertas concepciones epistemologicas erroneas acerca de las ciencias naturales, a la luz de la literatura consultada. Entre estas concepciones se destacan las siguientes: a) tendencia inductivista en el que las teorias cientificas comienzan con observaciones que establecen generalizaciones, b) secuencia jerarquica de la metodologia cientifica. Ademas, entre los docentes participantes de este estudio prevalecen concepciones epistemologicas adecuadas acerca de las ideologias, a la luz de la literatura consultada. Entre estas concepciones se destacan las siguientes: a) la funcion de las ideologias y b) la ausencia de validez ante el conocimiento cientifico. Sin embargo, en cuanto a considerar las ciencias naturales como una ideologia mas conocida como cientificismo, no hubo consistencia en las respuestas de los participantes por lo que no es posible afirmarlo o negarlo. Los hallazgos tambien revelaron que entre los docentes participantes hubo posiciones a favor y en contra para las dos situaciones sobre asuntos publicos relacionados a la ciencia que se presentaron. Estas posiciones fueron justificadas con argumentos cientificos y argumentos ideologicos, entre estos, los morales y los economicos. Con este dato se puede afirmar el uso de las ideologias en asuntos publicos relacionados a la ciencia.

The rampant success of quantum theory is the result of applications of the 'new' quantum mechanics of Schrodinger and Heisenberg (1926-7), the Feynman-Schwinger-Tomonaga Quantum Electro-dynamics (1946-51), the electro-weak theory of Salaam, Weinberg, and Glashow (1967-9), and Quantum Chromodynamics (1973-); in fact, this success of 'the' quantum theory has depended on a continuous stream of brilliant and quite disparate mathematical formulations. In this carefully concealed ferment there lie plenty of unresolved difficulties, simply because in churning out fabulously accurate calculational tools there has been no sensible explanation of all that is going on. It is even argued that such an understanding is nothing to do with physics. A long-standing and famous illustration of this is the paradoxical thought-experiment of Einstein, Podolsky and Rosen (1935). Fundamental to all quantum theories, and also their paradoxes, is the location of sub-microscopic objects; or, rather, that the specification of such a location is fraught with mathematical inconsistency. This project encompasses a detailed, critical survey of the tangled history of Position within quantum theories. The first step is to show that, contrary to appearances, canonical quantum mechanics has only a vague notion of locality. After analysing a number of previous attempts at a 'relativistic quantum mechanics', two lines of thought are considered in detail. The first is the work of Wan and students, which is shown to be no real improvement on the iisu.al 'nonrelativistic' theory. The second is based on an idea of Dirac's - using backwards-in-time light-cones as the hypersurface in space-time. There remain considerable difficulties in the way of producing a consistent scheme here. To keep things nicely stirred up, the author then proposes his own approach - an adaptation of Feynman's QED propagators. This new approach is distinguished from Feynman's since the propagator or Green's function is not obtained by Feynman's rule. The type of equation solved is also different: instead of an initial-value problem, a solution that obeys a time-symmetric causality criterion is found for an inhomogeneous partial differential equation with homogeneous boundary conditions. To make the consideration of locality more precise, some results of Fourier transform theory are presented in a form that is directly applicable. Somewhat away from the main thrust of the thesis, there is also an attempt to explain, the manner in which quantum effects disappear as the number of particles increases in such things as experimental realisations of the EPR and de Broglie thought experiments.

Costa Diaz, Agnes

El estudio que se presenta es de caracter cualitativo, un estudio multicasos donde se estudia la estructura logica utilizada por cuatro (4) profesores universitarios que ensenan el curso introductorio de quimica, en la planificacion, presentacion y evaluacion del tema sobre el comportamiento de los gases. Se utilizaron varias fuentes de informacion como: cuestionarios de profesores y estudiantes, entrevistas, grabaciones videomagnetofonicas, materiales didacticos y una prueba conceptual, entre otros. La informacion recopilada fue analizada de acuerdo al orden logico del contenido presentado, el estilo de ensenanza del profesor, las tecnicas y estrategias utilizadas para el desarrollo de destrezas de pensamiento, el ambiente fisico en el salon de clase y los instrumentos de evaluacion y avaluo. El estudio demuestra que lo que los profesores piensan y planifican para hacer sus presentaciones no necesariamente es lo que ocurre en el salon de clases. El desarrollo de destrezas de pensamiento, que constituye una prioridad de los profesores, no se elaboran efectivamente. El uso de las estrategias de resolucion de problemas numericos predomino. La participacion del estudiante en el salon de clases fue limitada y no se logro demostrar el desarrollo de las destrezas de pensamiento deseadas. Aunque los profesores tienen su propio estilo de ensenanza, el orden logico del contenido presentado en clase fue el mismo o siguio muy de cerca el orden establecido por el libro de texto. Los profesores utilizaron preferentemente la tiza y la pizarra para sus presentaciones y la dinamica en el salon de clases fue esencialmente tradicional. Los profesores hicieron su presentacion y los estudiantes copiaron pasivamente la informacion. Las evaluaciones de los estudiantes fueron esencialmente, pruebas escritas de seleccion multiple de acuerdo con el estilo en que se les enseno. El avaluo fue casi inexistente. La prueba conceptual administrada revela un aprendizaje pobre en los conceptos mas basicos sobre el comportamiento de los gases. El estudio senala que la ejecutoria del profesor en todos los aspectos de la ensenanza y el aprendizaje es un factor clave que debe darsele prioridad. Se recomienda que el profesor, en general, tenga un conocimiento basico de las teorias de aprendizaje, de los factores que afectan el aprendizaje y las tecnicas y estrategias mas efectivas en el desarrollo de destrezas de pensamiento entre sus estudiantes. La estructura de la disciplina debe incluir tanto lo experimental como lo teorico.

High School Students' Previous Knowledge about the Stars. (Spanish Title: Conocimientos Previos de Estudiantes de Secundaria Acerca de Las Estrellas.) O Conhecimento Prévio de Alunos do Ensino Médio sobre as Estrelas

Based on the readings of articles related to Astronomy Education published in Brazil, it was noticed a lack of research on previous knowledge of students about the physical characteristics of stars, a fact that motivated us to develop this study. Previous knowledge of 125 students (approximated 15 years old) constituted the study sample; data was collected through written questionnaires (Appendix A) for analysis. From the content analysis of these responses it was possible to achieve some inferences as, for example, many students have some difficult to develop an explanatory model on the functioning of a star; there are few who say that the stars have a certain length of existence; some students have said that stars have tips; few recognize that a star is formed by a mass of gas; some previous knowledge come from purely visual aspects; furthermore, some students do not have the habit of observing nature in detail. We see this research as a reference in which science teachers can recognize the importance of previous knowledge for practice teaching and acquire resources for planning their lessons. De la lectura de artículos relacionados con la Educación en Astronomía publicados en el Brasil, se encuentra una falta de investigaciones acerca del conocimiento previo de los estudiantes sobre las características físicas de las estrellas, hecho que nos motivó a desarrollar este estudio. Los datos analizados se obtuvieron al aplicar un cuestionario a 125 estudiantes de secundaria, para posteriormente realizar un análisis de contenido, tal cuestionario se presenta en el Anexo A. Al realizar el análisis de contenido de las respuestas obtenidas, fue posible hacer algunas inferencias, como por ejemplo; muchos estudiantes tienen dificultades para desarrollar un modelo explicativo acerca del funcionamiento de una estrella; pocos estudiantes dicen que las estrellas tienen un cierto tiempo de vida; algunos estudiantes imaginan que las estrellas tienen puntas; pocos reconocen que una estrella es formada por una masa de gas; varios conocimientos previos parten de aspectos puramente visuales; por otro lado, los estudiantes no tienen el hábito de observar la naturaleza detalladamente, entre otros problemas. Vemos esta investigación como una probable fuente de referencia en la que los profesores de ciencias pueden reconocer la importancia del conocimiento previo, y la forma como interfieren con su práctica de enseñanza, además de la adquisición de recursos para la planificación de sus clases. Com base em leituras de artigos relacionados ao ensino de Astronomia publicados no Brasil, verificou-se a inexistência de investigações sobre o conhecimento prévio de estudantes acerca das características físicas das estrelas, fato que nos motivou a desenvolver a pesquisa apresentada. Os conhecimentos prévios de 125 estudantes do primeiro ano do ensino médio constituíram os dados do estudo, os quais foram inferidos através da análise das respostas cedidas em questionários impressos (Apêndice A). A partir da análise de conteúdo dessas respostas tornou-se possível realizar algumas inferências como, por exemplo: vários estudantes possuem dificuldade em elaborar um modelo explicativo sobre o funcionamento de uma estrela; são poucos os que dizem que as estrelas possuem certo tempo de existência; alguns alunos as imaginam com pontas; poucos reconhecem que uma estrela é formada por uma massa de gás; vários conhecimentos prévios partem de aspectos meramente visuais; ainda assim, os estudantes não possuem o hábito de observar a natureza mais detalhadamente, entre outras. Vemos essa pesquisa como uma provável fonte de consulta na qual os professores de ciências poderão, além de reconhecer a importância dos conhecimentos prévios para o ensino e como eles interferem em sua prática, adquirir subsídios para o planejamento de suas aulas.

To analyze the perception of mothers about oral health of their children, as well as to check the influence of demographic variables, perception and preventive practice in oral health of mothers regarding guidance received during pregnancy. Quantitative and cross-sectional field study, with a non-probability sample formed by all mothers who attended the primary healthcare unit of Ijuí (RS), Brazil, from January to July 2014, comprising a sample of 79 women. Self-applied questionnaires were given to these mothers. Data analysis was carried out using descriptive and inferential statistics, the χ2 test at a significance level of 5%. The mothers who received dental orientation during pregnancy had greater perception of oral health of their children. The mean age of mothers was 26 years, most of them attended high school education (32.9%) and worked outside the home (60.8%). There was a statistically significant relation between the outcome variable, dental orientation during pregnancy, and the independent variables: schooling level of mothers, occupation, baby's first visit to the dentist, duration of breastfeeding, beginning of baby's tooth brushing and knowledge about dental decay (p<0.005). Mothers with higher schooling levels and who worked outside the home had more knowledge about oral care, because they received dental orientation during pregnancy. The dental guidance during pregnancy influences the mother in the procedures adopted with their children, as to early oral hygiene, first dentist appointment, duration of breastfeeding, knowledge about the factors that lead to dental decay. Analisar a percepção das mães em relação à saúde bucal de seus filhos, bem como verificar a influência das variáveis demográficas, de percepção e prática preventiva em saúde bucal das mães, na orientação odontológica recebida durante a gestação. Pesquisa de campo com abordagem quantitativa e delineamento transversal. A amostragem foi não probabilística com todas as mães que frequentaram o posto de saúde do município de Ijuí (RS), de janeiro a julho de 2014, compondo uma amostra de 79 mulheres. Foram distribuídos questionários autoaplicativos às mães participantes da pesquisa. A análise dos dados foi feita através de estatística descritiva e inferencial, pelo teste do χ2 com nível de significância de 5%. Mães que receberam orientação odontológica durante a gestação tiveram maior percepção sobre a saúde bucal de seus filhos. A média de idade das mães foi 26 anos, e a maioria delas frequentou o ensino médio completo (32,9%) e trabalhava fora de casa (60,8%). Houve uma relação estatisticamente significativa entre a variável desfecho, orientação odontológica durante a gestação e as variáveis independentes: escolaridade das mães, ocupação, primeira visita do bebê ao dentista, tempo de amamentação natural, início da escovação do bebê e conhecimento sobre a cárie dentária (p<0,005). As mães com maior nível de escolaridade e que trabalhavam fora de casa tinham mais conhecimento sobre atenção odontológica, pois receberam orientação odontológica na gestação. A orientação odontológica recebida na gestação influencia as mães nos procedimentos adotados com seus filhos, em relação ao início da higienização bucal, primeira consulta ao dentista, tempo de amamentação, o conhecimento sobre os fatores que levam ao aparecimento da cárie dentária.

This article is the result of a research on basic training in Astronomy in physics degrees that performed the ENADE 2011 national examination. The objective was to identify whether there are disciplines of Astronomy in these courses, whether are mandatory or optional, its workload and when it is offered. The relationship between astronomers, physics degrees and disciplines of Astronomy was investigated. To perform this research we examined the results of ENADE 2011 and also the census of Brazilian Astronomical Society. As a result it is observed that in only 15% of the courses there is a mandatory subject of Astronomy, and therefore there is a high probability that 85% of physics teachers trained in 2011 have not had any discipline of Astronomy during their graduation. In addition, the data collected in this study shows a low number of members of SAB (Sociedade Astronômica Brasileira) among the surveyed courses. We have verified that the presence of astronomers in a given university does not imply to have a mandatory discipline of Astronomy in physics degrees at the same university. Este artículo es el resultado de una investigación sobre la formación básica en Astronomía en los cursos de Profesorado en Física que hicieron el examen nacional ENADE 2011. El objetivo del trabajo fue identificar se existen disciplinas de Astronomía en estos cursos, si son obligatorias u optativas, cuál es su carga horaria y el semestre en que son ofrecidas. Se investigó también la correlación entre astrónomos, los cursos de licenciatura en Física y las disciplinas de Astronomía. Para realizar esta investigación se utilizaron los datos del ENADE 2011 y también del censo de la Astronomía brasileña. Como resultado, se observó que en solo 15% de los cursos existe una disciplina obligatoria de Astronomía y que existe una grande probabilidad de que 85% de los profesores de Física formados en el año de 2011 no hayan cursado ninguna disciplina de Astronomía durante su formación. Aparte de eso, los datos levantados en este trabajo apuntan para un número bajo de afiliados a la SAB (Sociedade Astronômica Brasileira) en los cursos investigados. Se verificó que tener astrónomos en una institución no implica tener una disciplina obligatoria de Astronomía en el curso de licenciatura en Física. Este artigo é o resultado de uma pesquisa sobre a formação básica em Astronomia nos cursos de Licenciatura em Física que fizeram o exame nacional ENADE 2011. O objetivo do trabalho foi identificar se há disciplinas de Astronomia nesses cursos, se ela é obrigatória ou optativa/eletiva, qual a sua carga horária e o período em que é oferecida. Pesquisou-se também a relação entre astrônomos, cursos de Licenciatura em Física e disciplinas de Astronomia. Para realizar essa pesquisa utilizamos os dados do ENADE 2011 e também do censo da Astronomia brasileira. Como resultado, se observa que em apenas 15% dos cursos existe uma disciplina obrigatória de Astronomia e que há uma grande probabilidade de que 85% dos professores de Física formados em 2011 não cursaram nenhuma disciplina de Astronomia durante a graduação. Além disso, os dados levantados nesse trabalho apontam um baixo número de filiados à SAB nos cursos pesquisados. Identifica-se que ter astrônomos na instituição não implica em disciplina obrigatória de Astronomia no curso de Licenciatura em Física.

This study aims to describe the places of purchase of food consumed outside the home, characterize consumers according to the places of consumption, and identify the food purchased by place of consumption in Brazil. We have used data from the Pesquisa de Orçamento Familiar (Household Budget Survey) of 2008-2009 with a sample of 152,895 subjects over 10 years of age. The purchase of food outside the home was collected from the records of all expenditures made in seven days. The places of purchase were grouped according to their characteristics: supermarket, bakery, street food, restaurant, snack bar, fruit shop, and other places. The types of food were grouped into nine categories, considering the nutritional aspects and the marketing characteristics of the item. We have estimated the frequency of purchase in the seven groups of places in Brazil and according to gender and type of food purchased per place. We have calculated the average age, income and years of education, as well as the per capita expenditure according to places of purchase of food consumed outside the home. The purchase of food outside the home was reported by 41.2% of the subjects, being it greater among men than women (44% versus 38.5%). Adults had a higher frequency (46%) than teenagers (37.7%) and older adults (24.2%). The highest frequency of places of purchase were snack bar (16.9%) and restaurant (16.4%), while the fruit shop (1.2%) presented the lowest frequency. Sweets, snack chips and soft drinks were the most purchased items in most places. Average expenditure was higher for restaurant (R$33.20) and lower for fruit shop (R$4.10) and street food (R$5.00). The highest percentage of food consumed outside the home comes from snack bars and restaurants, pointing to important places for the development of public policies focused on promoting healthy eating. Descrever os locais de aquisição dos alimentos consumidos fora do lar, caracterizar os consumidores de acordo com os locais de consumo e identificar os alimentos adquiridos por local de consumo no Brasil. Utilizaram-se dados da Pesquisa de Orçamento Familiar 2008-2009 em uma amostra de 152.895 indivíduos acima de 10 anos. A aquisição de alimentos para consumo fora do lar foi coletada por registros de todos os gastos realizados no período de sete dias. Os locais de aquisição de alimentos foram agrupados de acordo com suas características: supermercado, padaria, comida de rua, restaurante, lanchonete, frutaria e outros. Os tipos de alimentos adquiridos foram alocados em nove categorias de alimentos, considerando os aspectos nutricionais e as características de comercialização do item. Estimou-se a frequência de aquisição de alimentos nos sete grupos de locais no Brasil e por sexo e o tipo de alimento adquirido por local. Calculou-se a média de idade, de renda e de anos de escolaridade, bem como da despesa per capita segundo locais de aquisição de alimentos consumidos fora do lar. A aquisição de alimentos fora do lar foi reportada por 41,2% dos indivíduos, sendo maior entre os homens do que nas mulheres (44% versus 38,5%). Os adultos apresentaram maior frequência de aquisição (46%) do que os adolescentes (37,7%) e os idosos (24,2%). Os locais com maiores frequências de consumo de alimentos fora do lar foram lanchonete (16,9%) e restaurante (16,4%), enquanto frutaria (1,2%) apresentou a menor frequência. Doces, salgadinhos e refrigerante foram os alimentos mais adquiridos na maioria dos locais. Os gastos médios com alimentos foram maiores para restaurante (R$33,20) e menores para frutaria (R$4,10) e comida de rua (R$5,00). O maior percentual de consumo de alimentos fora do lar é proveniente de lanchonete e restaurante, apontando importantes locais para o desenvolvimento de políticas públicas com foco na promoção da alimentação saudável.

PrEP Brasil was a demonstration study to assess feasibility of daily oral tenofovir diphosphate disoproxil fumarate plus emtricitabine provided at no cost to men who have sex with men (MSM) and transgender women at high risk for HIV within the Brazilian public health system. We report week 48 pre-exposure prophylaxis (PrEP) retention, engagement, and adherence, trends in sexual behaviour, and incidence of HIV and sexually transmitted infections in this study cohort. PrEP Brasil was a 48 week, open-label, demonstration study that assessed PrEP delivery at three referral centres for HIV prevention and care in Rio de Janeiro, Brazil (Fundação Oswaldo Cruz), and São Paulo, Brazil (Universidade de São Paulo and Centro de Referência e Treinamento em DST e AIDS). Eligible participants were MSM and transgender women who were HIV negative, aged at least 18 years, resident in Rio de Janeiro or São Paulo, and reported one or more sexual risk criteria in the previous 12 months (eg, condomless anal sex with two or more partners, two or more episodes of anal sex with an HIV-infected partner, or history of sexually transmitted infection [STI] diagnosis). Participants were seen at weeks 4, 12, 24, 36, and 48 for PrEP provision, clinical and laboratory evaluation, and HIV testing. Computer-assisted self-interviews were also done at study visits 12, 24, 36, and 48, and assessed sexual behaviour and drug use. PrEP retention was defined by attendance at the week 48 visit, PrEP engagement was an ordinal five-level variable combining presence at the study visit and drug concentrations, and PrEP adherence was evaluated by measuring tenofovir diphosphate concentrations in dried blood spots. Logistic regression models were used to quantify the association of variables with high adherence (≥4 doses per week). The study is registered with ClinicalTrials.gov, number NCT01989611. Between April 1, 2014, and July 8, 2016, 450 participants initiated PrEP, 375 (83%) of whom were retained until week 48. At week 48, 277 (74%) of 375 participants had protective drug concentrations consistent with at least four doses per week: 183 (82%) of 222 participants from São Paulo compared with 94 (63%) of 150 participants from Rio de Janeiro (adjusted odds ratio 1·88, 95% CI 1·06-3·34); 119 (80%) of 148 participants who reported sex with HIV-infected partners compared with 158 (70%) of 227 participants who did not (1·78, 1·03-3·08); 67 (87%) of 77 participants who used stimulants compared with 210 (71%) of 298 participants who did not (2·23, 1·02-4·92); and 232 (80%) of 289 participants who had protective concentrations of tenofovir disphosphate at week 4 compared with 42 (54%) of 78 participants who did not (3·28, 1·85-5·80). Overall, receptive anal sex with the last three partners increased from 45% at enrolment to 49% at week 48 (p=0·17), and the mean number of sexual partners in the previous 3 months decreased from 11·4 (SD 28·94) at enrolment to 8·3 (19·55) at week 48 (p<0·0013). Two individuals seroconverted during follow-up (HIV incidence 0·51 per 100 person-years, 95% CI 0·13-2·06); both of these patients had undetectable tenofovir concentrations at seroconversion. Our results support the effectiveness and feasibility of PrEP in a real-world setting. Offering PrEP at public health-care clinics in a middle-income setting can retain high numbers of participants and achieve high levels of adherence without risk compensation in the investigated populations.

Dyslipidemia occurs in approximately 70% of all liver transplant (LT) recipients, and no prior control studies have demonstrated any dietary intervention to change it. To analyze the effects of a dietary intervention on the lipid profile of dyslipidemic LT recipients. All LT recipients with dyslipidemia on clinical follow-up were enrolled. Anthropometric evaluation, food history, body composition (bioimpedance) and assessment of basal metabolism through indirect calorimetry were performed. Patients met with a dietitian and an individualized diet based on estimate of basal metabolism and consisting of 25% of the total energy value in total fat and <200 mg/day of cholesterol was prescribed. Total cholesterol (TC), HDL-cholesterol (HDL), LDL-cholesterol (LDL), triglycerides (TG) and anthropometric measures were measured at baseline and six months after intervention. Fifty-thee out of 56 patients concluded follow-up; age was 59±10 years; 29 were men (51.8%). The analysis pre- and post-intervention were, respectively: TC 238.9±30 and 165.1±35, p<0.001; LDL 154±33 and 90±29, p<0.001; and TG 168 (IQR=51-200) and 137 (IQR=94-177), p=<0.001. They were all modified at six months following intervention. At baseline, none of the patients had normal TC, and only 12 (22.7%) had optimal/near optimal LDL. Following dietary intervention, 45 patients (84.9%) reached normal TC and 50 (94.4%) had optimal/near optimal LDL. HDL and anthropometric measures were not modified. Dietary counseling with prescription of individualized diet based on estimate of basal metabolism through indirect calorimetry was able to manage dyslipidemia in most LT recipients; so, all dyslipidemic LT recipients must be enrolled on a dietary program. A dislipidemia ocorre em aproximadamente 70% de todos os pacientes transplantados de fígado em acompanhamento ambulatorial. Não há relato prévio de qualquer intervenção dietética que houvesse controlado a dislipidemia nesse grupo de pacientes. Analisar os efeitos de uma intervenção dietética no perfil lipídico de pacientes transplantados hepáticos dislipidêmicos em acompanhamento ambulatorial. Foram incluídos todos os pacientes adultos transplantados hepáticos com dislipidemia e em acompanhamento ambulatorial em nossa instituição. Avaliação antropométrica, anamnese alimentar, composição corporal (bioimpedância) e cálculo do metabolismo basal (calorimetria indireta) foram realizados. Pacientes foram atendidos por uma nutricionista e uma dieta individualizada baseada no metabolismo basal e consistindo de 25% do valor energético em gorduras totais e menos de 200 mg/dia de colesterol foi prescrita. Colesterol total (CT), HDL-colesterol (HDL), LDL-colesterol (LDL), triglicerídeos (TG) e medidas antropométricas foram medidos antes do início da dieta, sendo repetidos seis meses após o início da intervenção dietética. Cinquenta e três pacientes concluíram o seguimento e tinham idade 59±10 anos e 29 eram homens (51,8%). CT pré-intervenção=238,9±30; pós-intervenção=165,1±35, p<0.001; LDL pré-intervenção=154±33; pós-intervenção=90±29, p<0.001 e TG pré-intervenção=168, IQR=151-200; pós-intervenção=137, IQR=94-177, p=<0.001 sofreram modificações significativas seis meses após a intervenção. Antes do estudo, nenhum dos pacientes apresentava níveis séricos normais para o CT, e apenas 12 pacientes (22,7%) tinham níveis séricos ótimo ou quase ótimos para o LDL. Seis meses após o início da intervenção, 45 pacientes (84,9%) alcançaram níveis séricos normais de CT e 50 (94,4%) níveis séricos ótimos ou quase ótimos de LDL. Os níveis séricos de HDL e as medidas antropométricas não sofreram modificações significativas. Aconselhamento dietético com prescrição de dieta individualizada baseada no cálculo do metabolismo basal mostrou-se efetivo no manejo da dislipidemia em pacientes transplantados hepáticos em seguimento ambulatorial. Assim, todos os pacientes transplantados hepáticos com dislipidemia devem ser incluídos em um programa de intervenção dietética sob orientação de nutricionista.

Abstract United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We analyzed the spatial and temporal patterns of mortality of large whales in the Northwest Atlantic (23.5°N to 48.0°N), 1970 through 2009, in the context of management changes. We used a multinomial logistic model fitted by maximum likelihood to detect trends in cause-specific mortalities with time. We compared the number of human-caused mortalities with U.S. federally established levels of potential biological removal (i.e., species-specific sustainable human-caused mortality). From 1970 through 2009, 1762 mortalities (all known) and serious injuries (likely fatal) involved 8 species of large whales. We determined cause of death for 43% of all mortalities; of those, 67% (502) resulted from human interactions. Entanglement in fishing gear was the primary cause of death across all species (n = 323), followed by natural causes (n = 248) and vessel strikes (n = 171). Established sustainable levels of mortality were consistently exceeded in 2 species by up to 650%. Probabilities of entanglement and vessel-strike mortality increased significantly from 1990 through 2009. There was no significant change in the local intensity of all or vessel-strike mortalities before and after 2003, the year after which numerous mitigation efforts were enacted. So far, regulatory efforts have not reduced the lethal effects of human activities to large whales on a population-range basis, although we do not exclude the possibility of success of targeted measures for specific local habitats that were not within the resolution of our analyses. It is unclear how shortfalls in management design or compliance relate to our findings. Analyses such as the one we conducted are crucial in critically evaluating wildlife-management decisions. The results of these analyses can provide managers with direction for modifying regulated measures and can be applied globally to mortality-driven conservation issues. Evaluación del Manejo para Mitigar Efectos Antropogénicos sobre Ballenas Mayores Resumen Los gobiernos de Estados Unidos y Canadá han respondido a requerimientos legales para reducir la mortalidad de ballenas inducida por humanos por medio de impacto con embarcaciones y enmarañamiento en artes de pesca mediante la implementación de un conjunto de acciones reguladoras. Analizamos los patrones espaciales y temporales de la mortalidad de ballenas mayores en el Atlántico Noroccidental (23.5°N a 48.0°N), de 1970 a 2009, en el contexto de cambios de manejo. Utilizamos un modelo logístico multinomial ajustado por la máxima probabilidad de detección de tendencias en mortalidades por causa específica en el tiempo. Comparamos el número de muertes provocadas por humanos con los niveles de remoción biológica potencial (i.e., mortalidad específica provocada por humanos sustentable). De 1970 a 2009, hubo 1762 muertes (conocidas) y lesiones serias (casi fatales) involucrando 8 especies de ballenas mayores. Determinamos la causa de 43% de todas las muertes; de ellas, 67% (502) resultaron de interacciones humanas. El enmarañamiento en artes de pesca fue la causa principal de muerte en todas las especies (n = 323), seguida de causas naturales (n = 248) e impacto de embarcaciones (n = 171). Los niveles sustentables de mortalidad establecidos fueron excedidos consistentemente hasta en 650% en 2 especies. Las probabilidades de muerte por enmarañamiento y por impacto de embarcaciones incrementaron significativamente de 1990 a 2009. No hubo cambio significativo en la intensidad local de mortalidad por todas las causas o por impacto de embarcaciones antes y después de 2003, año en el que se implementaron numerosos esfuerzos de mitigación. Hasta ahora, los esfuerzos regulatorios no han reducido los efectos letales de las actividades humanas sobre las ballenas a nivel de población, aunque no excluimos la posibilidad de éxito de medidas enfocadas a hábitats locales específicos que no estuvieron dentro de la resolución de nuestro análisis. No es claro como se relacionan con nuestros resultados las deficiencias en el diseño o implementación del manejo. Análisis como el que realizamos son cruciales para la evaluación crítica de decisiones para el manejo de vida silvestre, y los resultados de estos análisis pueden proporcionar directrices a los manejadores para que modifiquen medidas regulatorias y puedan ser aplicadas globalmente en temas de conservación relacionadas con mortalidad.

to analyze the effects of acupressure on the sanyinjiao point for pregnant women in labor at public maternity wards. single-blind controlled clinical trial, randomly done employing a pragmatic profile. We selected 156 pregnant women in their ≥ 37 week/s, who had cervical dilations of ≥ 4 cm and with two or more contractions in 10 minutes. The pregnant women were randomly divided into three groups at a university hospital in the suburbs of Sao Paulo, Brazil, in order to receive either acupressure treatment, a placebo or participate as part of a control group. The acupressure was applied on the sanyinjiao point during the contractions for 20 minutes. Then the intensity of the pain was evaluated using the Visual Analogue Scale (VAS). The averages for the pain measured using the VAS were not different for the three groups that were a part of the study (p-value=0.0929), however they were less in the acupressure groups immediately after receiving the treatment (p-value=<0.0001). This was also the case where the treatment lasted for 1 hour (p-value=0.0001). This was the case in comparison with placebo and control groups. the use of acupressure on the sanyinjiao point is a useful way to alleviate pain in a non-invasive manner. It can improve the quality of care given to pregnant women in labor.

Hydraulic properties and scale effects investigation in regional rock aquifers, south-western Quebec, Canada

Nastev, M.; Savard, M. M.; Lapcevic, P.; Lefebvre, R.; Martel, R.

This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua subterránea sucede en los primeros metros de la secuencia rocosa. A escala regional se puede aplicar la aproximación equivalente de medios porosos. Las medidas de la conductividad hidrálica fueron comparadas con la escala de las pruebas del acuífero, expresadas con el volumen investigado del acuífero. Se desarrolló un proceso de interpolación simple para la conductividad hidráulica de campo, con base en la distancia entre las medidas de campo y los volúmenes probados del acuífero. La distribución regional de la conductividad hidráulica, para las unidades acuíferas fracturadas mayores, indica que la dolomita es más permeable mientras que la arenisca y las rocas cristalinas son las unidades menos permeables. L'article présente les propriétés hydrauliques d'un aquifère régional rocheux qui ont été mesurées dans le cadre d'un projet concernant l'estimation de la ressource en eau de la plaine de St. Lawrence située dans la partie sud-ouest de Quebec. Affin de comprendre le comportement de l'aquifère tant à l'échelle de fracture qu'à l'échelle régionale on a mené des investigations hydrauliques en utilisant des essais differents. À l'échelle locale l'écoulement est déterminé en principal par le système des fractures. Les résultats des essais d'injection au niveau constant ont montré une tendence de décroissance de la conductivité hydraulique avec la profondeur ce qui indique que l'écoulement ait lieu en principal dans les premiers mètres de la structure rocheuse. À l'échelle règionale on peut appliquer l'approche de milieux poreux equivalent. Les mesures de conductivité hydraulique ont été corrélées avec l'échelle des essais de pompage exprimée en termes de volume investigué de l'aquifère. On a mis au point une méthode simple d'interpolation pour le champ de la conductivité hydraulique basée sur la distance entre les essais in situ et les volume investigués de l'aquifère. La distribution règionale de la conductivité hydraulique montre que pour la majorité des unités de roche fracturé les plus perméable sont les roches dolomitiques alors que les grés et les roches cristalines presentent la plus faible perméabilité.

To identify women's complaints about pain in the immediate postpartum of vaginal delivery and cesarean section; to measure the intensity of pain in postpartum women at rest and with selected movements and to compare the activity limitations in relation to the mode of delivery and parity. Observational, descriptive, cross-sectional study. Eighty-six women, in the immediate postpartum period after vaginal delivery (n=43) and cesarean section (n=43), were evaluated for physical discomforts and their difficulty in performing functional activities. Abdominal pain (mean differences=-39.5%; 95% CI=-57.3 to -21.8%), neck pain (mean differences=-16.3%; 95% CI=-32.3 to -0.3%) and edema (mean differences=-41.4%; 95% CI=-63.3 to -20.4%) were reported of cesarean women postpartum. Perineal pain (p<0.05) was reported in vaginal delivery women postpartum. Postpartum pain was more severe during movement after cesarean section (p<0.05) resulting in pain during the activities of sitting down (mean differences=-30.2%; 95% CI=-50.7 to -9.8%), standing up from a sitting position (mean differences=-46.5%; 95% CI=-65.0 to -28.0%), walking (mean differences=-44.2%; 95% CI=-65.2 to -23.1%), lying down (mean differences=-32.6%; 95% CI=-54.9 to -10.3%) and taking a bath (mean differences=-24.0%; 95% CI=-43.1 to -5.0%). Correspondence analysis found no association between parity and functional limitations. The highest number of complaints was associated with movement activities and cesarean section postpartum. There was no relationship between functional limitations and parity in this study. Copyright © 2017 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

OBJECTIVE To assess the impact of consuming ultra-processed foods on the nutritional dietary profile in Brazil. METHODS Cross-sectional study conducted with data from the module on individual food consumption from the 2008-2009 Pesquisa de Orçamentos Familiares (POF – Brazilian Family Budgets Survey). The sample, which represented the section of the Brazilian population aged 10 years or over, involved 32,898 individuals. Food consumption was evaluated by two 24-hour food records. The consumed food items were classified into three groups: natural or minimally processed, including culinary preparations with these foods used as a base; processed; and ultra-processed. RESULTS The average daily energy consumption per capita was 1,866 kcal, with 69.5% being provided by natural or minimally processed foods, 9.0% by processed foods and 21.5% by ultra-processed food.

OBJECTIVE To assess the impact of consuming ultra-processed foods on the nutritional dietary profile in Brazil. METHODS Cross-sectional study conducted with data from the module on individual food consumption from the 2008-2009 Pesquisa de Orçamentos Familiares (POF - Brazilian Family Budgets Survey). The sample, which represented the section of the Brazilian population aged 10 years or over, involved 32,898 individuals. Food consumption was evaluated by two 24-hour food records. The consumed food items were classified into three groups: natural or minimally processed, including culinary preparations with these foods used as a base; processed; and ultra-processed. RESULTS The average daily energy consumption per capita was 1,866 kcal, with 69.5% being provided by natural or minimally processed foods, 9.0% by processed foods and 21.5% by ultra-processed food. The nutritional profile of the fraction of ultra-processed food consumption showed higher energy density, higher overall fat content, higher saturated and trans fat, higher levels of free sugar and less fiber, protein, sodium and potassium, when compared to the fraction of consumption related to natural or minimally processed foods. Ultra-processed foods presented generally unfavorable characteristics when compared to processed foods. Greater inclusion of ultra-processed foods in the diet resulted in a general deterioration in the dietary nutritional profile. The indicators of the nutritional dietary profile of Brazilians who consumed less ultra-processed foods, with the exception of sodium, are the stratum of the population closer to international recommendations for a healthy diet. CONCLUSIONS The results from this study highlight the damage to health that is arising based on the observed trend in Brazil of replacing traditional meals, based on natural or minimally processed foods, with ultra-processed foods. These results also support the recommendation of avoiding the consumption of these kinds of foods.

Muscle strength is an important component of health. To describe and evaluate the studies which have established the reference values for muscle strength on healthy individuals and to synthesize these values with a descriptive meta-analysis approach. A systematic review was performed in MEDLINE, LILACS, and SciELO databases. Studies that investigated the reference values for muscle strength of two or more appendicular/axial muscle groups of health individuals were included. Methodological quality, including risk of bias was assessed by the QUADAS-2. Data extracted included: country of the study, sample size, population characteristics, equipment/method used, and muscle groups evaluated. Of the 414 studies identified, 46 were included. Most of the studies had adequate methodological quality. Included studies evaluated: appendicular (80.4%) and axial (36.9%) muscles; adults (78.3%), elderly (58.7%), adolescents (43.5%), children (23.9%); isometric (91.3%) and isokinetic (17.4%) strength. Six studies (13%) with similar procedures were synthesized with meta-analysis. Generally, the coefficient of variation values that resulted from the meta-analysis ranged from 20.1% to 30% and were similar to those reported by the original studies. The meta-analysis synthesized the reference values of isometric strength of 14 muscle groups of the dominant/non-dominant sides of the upper/lower limbs of adults/elderly from developed countries, using dynamometers/myometer. Most of the included studies had adequate methodological quality. The meta-analysis provided reference values for the isometric strength of 14 appendicular muscle groups of the dominant/non-dominant sides, measured with dynamometers/myometers, of men/women, of adults/elderly. These data may be used to interpret the results of the evaluations and establish appropriate treatment goals. Copyright © 2018 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 < i' < 25 observou-se que estas galáxias estão localizadas próximas a um dos quasares e há indícios de que estejam aglomeradas dentro de um área de ~ 6 arcmin2. Se esse for o caso, estes objetos seriam membros de uma estrutura em grande escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

A astronomia, embora seja uma ciência popular, com inúmeras descobertas de interesse público, ainda é apresentada desconsiderando-se os aspectos históricos e científicos relacionados ao seu desenvolvimento, sendo geralmente veiculada nos meios de comunicação de maneira pouco esclarecedora e não raro com imprecisões. Neste trabalho analisou-se a concepção de um grupo de estudantes de Ensino Médio sobre conceitos de astronomia, visando identificar sua visão de mundo a respeito do Universo, envolvendo idéias sobre espaço e tempo. Para issso, foi aplicado um questionário em três escolas da grande São Paulo em um espaço amostral de 270 alunos. Constatou-se que, embora o ensino de astronomia esteja previsto nos PCNEM, os resultados obtidos na pesquisa mostram que há grande deficiência no conhecimento dos temas investigados. Nesse sentido, verificou-se que apenas 20% dos alunos eram capazes de relacionar a sucessão das semanas com as fases da lua, enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra. Por outro lado, somente 23% dos alunos tinham noções das distâncias entre os objetos celestes próximos da Terra e 56% conseguiram relacionar o Big Bang com a origem do Universo. Finalmente, constatou-se que 37% reconheciam o ano-luz como uma unidade de distância e 60% reconheciam o Sol como sendo uma estrela. Apesar de 60% dos alunos indicarem que a escola é a principal fonte para aquisição dos conhecimentos de astronomia, conclui-se que seus conceitos nessa área ainda são inadequados, havendo necessidade de ampliação e aprimoramento da abordagem desses conteúdos nos ambientes escolares.

To analyze the care provided by Basic Health Units (BHU) to families involved in domestic intrafamily violence against children and adolescents. Qualitative research, based on the Paradigm of Complexity. Data collection was performed with 41 professionals through focus groups and semi-structured interviews. The following categories emerged from data analysis: 'Everything comes here', which reflects the legitimate place of BHUs for the population and the actions taken to build care for families; and 'We only do what is really necessary', which brings the look to violence still based on the positivist and biomedical paradigm. The model of understanding and construction of work processes in the BHU is structured in the aforementioned paradigm. Nurses have the possibility to become agents of change, both in professionals' training and in the care thought and provided to communities. Analisar o cuidado realizado por Unidades Básicas de Saúde (UBS) junto a famílias envolvidas na violência intrafamiliar contra crianças e adolescentes. Pesquisa qualitativa, fundamentada no Paradigma da Complexidade. A coleta de dados foi realizada com 41 profissionais, por meio de grupos focais e entrevistas semiestruturadas. Da análise dos dados, emergiram as seguintes categorias: "Tudo desemboca aqui", que reflete o lugar legitimado das UBSs para a população e as ações realizadas para construção do cuidado às famílias; e "A gente só faz o que é indispensável mesmo", que traz o olhar para a violência ainda pautado no paradigma positivista e biomédico. O modelo de compreensão e construção dos processos de trabalho na UBS é estruturado no último paradigma citado. O enfermeiro tem a possibilidade de se colocar como um agente de mudanças, tanto na formação dos profissionais quanto no cuidado pensado e executado junto às comunidades.

Combination antiretroviral therapy (cART) had a dramatic impact on the mortality profile in human immunodeficiency virus (HIV) infected individuals and increased their life-expectancy. Conditions associated with the aging process have been diagnosed more frequently among HIV-infected patients, particularly, cardiovascular diseases. Patients followed in the Instituto de Pesquisa Clínica Evandro Chagas (IPEC) prospective cohort in Rio de Janeiro were submitted to the general procedures from the Brazilian Longitudinal Study of Adult Health, comprising several anthropometric, laboratory and imaging data. Carotid intima-media thickness (cIMT) was measured by ultrasonography, following the Mannheim protocol. Linear regression and proportional odds models were used to compare groups and covariables in respect to cIMT. The best model was chosen with the adaptive lasso procedure. A valid cIMT exam was available for 591 patients. Median cIMT was significantly larger for men than women (0.56mm vs. 0.53mm; p = 0.002; overall = 0.54mm). In univariable linear regression analysis, both traditional risk factors for cardiovascular diseases (CVD) and HIV-specific characteristics were significantly associated with cIMT values, but the best multivariable model chosen included only traditional characteristics. Hypertension presented the strongest association with higher cIMT terciles (OR = 2.51; 95%CI = 1.69-3.73), followed by current smoking (OR = 1,82; 95%CI = 1.19-2.79), family history of acute myocardial infarction or stroke (OR = 1.60; 95%CI = 1.10-2.32) and age (OR per year = 1.12; 95%CI = 1.10-1.14). Our results show that traditional cardiovascular disease (CVD) risk factors are the major players in determining increased cIMT among HIV infected patients in Brazil. This finding reinforces the need for thorough assessment of those risk factors in these patients to guarantee the incidence of CVD events remain under control.

To analyze the influence of health professionals' receptiveness on parental care of children with retinopathy of prematurity (ROP). A qualitative study developed under the theoretical framework of Symbolic Interactionism and using a narrative research methodology. Six women and three men, being parents of children with retinopathy of prematurity were individually interviewed in depth. From the scope of information, emotions and their rights, the parents experienced receptiveness from some professionals and unreceptiveness from others. The predominance of unreceptive attitudes in the parental narratives originated the following analysis themes: Informational (un)receptiveness, Emotional (un)receptiveness, and (Un)receptiveness of rights. The study supports human and comprehensive healthcare in the context of retinopathy of prematurity by pointing out the interactive process with health professionals as a potential stressor of parental care. The results signal a nuclear of attitudinal changes and reinforce challenges to the child and family-centered approach. Analisar a influência do acolhimento do profissional de saúde no cuidado parental junto ao filho com retinopatia da prematuridade. Estudo qualitativo desenvolvido sob o referencial teórico do Interacionismo Simbólico e metodológico da pesquisa de narrativas. Foram entrevistados em profundidade e individualmente seis mulheres e três homens, pais de crianças com retinopatia da prematuridade. Os pais vivenciam, nos âmbitos informacional, emocional e de direitos, acolhimento com alguns profissionais e destrato com outros. A predominância da postura de desacolhimento nas narrativas parentais deu origem aos temas de análise: (Des)acolhimento informacional, (Des)acolhimento emocional, e (Des)acolhimento de direitos. O estudo oferece subsídios ao cuidado humano e integral em saúde no contexto da retinopatia da prematuridade ao apontar o processo interativo com os profissionais de saúde enquanto potencial estressor do cuidado parental. Os resultados sinalizam núcleos de mudanças atitudinais e reforçam desafios à abordagem centrada na criança e família.

The Monitor e Imageador de Raios-X (MIRAX) is a small (~250 kg) X-ray astronomy satellite mission designed to monitor the central Galactic plane for transient phenomena. With a field-of-view of ~1000 square degrees and an angular resolution of ~6 arcmin, MIRAX will provide an unprecedented discovery-space coverage to study X-ray variability in detail, from fast X-ray novae to long-term (~several months) variable phenomena. Chiefly among MIRAX science objectives is its capability of providing simultaneous complete temporal coverage of the evolution of a large number of accreting black holes, including a detailed characterization of the spectral state transitions in these systems. MIRAX's instruments will include a soft X-ray (2-18 keV) and two hard X-ray (10-200 keV) coded-aperture imagers, with sensitivities of ~5 and ~2.6 mCrab/day, respectively. The hard X-ray imagers will be built at the Instituto Nacional de Pesquisas Espaciais (INPE), Brazil, in close collaboration with the Center for Astrophysics & Space Sciences (CASS) of the University of California, San Diego (UCSD) and the Institut fur Astronomie und Astrophysik of the University of Tubingen (IAAT) in Germany; UCSD will provide the crossed-strip position-sensitive (0.5- mm spatial resolution) CdZnTe (CZT) hard X-ray detectors. The soft X-ray camera, provided by the Space Research Organization Netherlands (SRON), will be the spare flight unit of the Wide Field Cameras that flew on the Italian-Dutch satellite BeppoSAX. MIRAX is an approved mission of the Brazilian Space Agency (Agnecia Espacial Brasileira - AEB) and is scheduled to be launched in 2011 in a low-altitude (~550 km) circular equatorial orbit. In this paper we present recent developments in the mission planning and design, as well as Monte Carlo simulations performed on the GEANT-based package MGGPOD environment (Weidenspointner et al. 2004) and new algorithms for image digital processing. Simulated images of the central Galactic plane as it would be seen by MIRAX are shown.

Sacroiliac joint manipulation can alter joint and muscle control mechanisms through local and remote effects. Postural balance is controlled by supraspinal (rambling) and spinal-peripheral (trembling) mechanisms. A manipulation may interfere with postural control in quiet standing. To evaluate the immediate effects of sacroiliac joint manipulation on postural control in patients with (1) sacroiliac dysfunction and (2) to determine whether rambling and trembling are affected by sacroiliac joint manipulation. 32 patients aged between 20 and 50 years old were selected by convenience after confirmation of sacroiliac joint dysfunction by clinical examination. These patients were randomly allocated either to manipulation or sham manipulation group. Displacement, velocity and frequency of the center of pressure, rambling and trembling in the anterior-posterior and medial-lateral directions were our primary outcomes and analyzed immediately before and after the intervention in quiet standing. The physical therapists who performed the physical, biomechanical and statistical examinations, were all blinded to the patients' grouping. No differences were found between the two groups but trembling velocity (0.14 and -0.11 for intervention and sham group, respectively) and frequency (0.17 and 0.11 for intervention and sham group respectively) increased after intervention in the treatment group in the anterior-posterior direction. Generally, sacroiliac joint manipulation had no superiority than sham treatment regarding postural control as measured by rambling-trembling analysis of center of pressure. Manipulation may increase muscle activation in the treatment group due to increased trembling parameters.

Formaldehyde (HCHO) and glyoxal (CHOCHO) are important tracers for oxidative processes in the atmosphere such as oxidation of volatile organic compounds (VOCs) and production of HO2 radicals by photolysis or reaction with OH. Products of VOC oxidation and radical cycling, such as aerosols and tropospheric ozone, have direct impacts on human health. During the Green Ocean Amazon campaign (GoAmazon2014/5), HCHO and CHOCHO measurements were obtained together with OH, RO2+HO2, CO, CO2, O3, NOx, (o)VOCs, and aerosol particle size distribution. HCHO concentration was measured by the Madison FIber Laser-Induced Fluorescence (FILIF) instrument, while CHOCHO concentrations were collected by the Madison Laser-Induced Phosphorescence (Mad-LIP) instrument. Here we present data collected during 2014 at the T3 field site, 60 km to the west of Manaus, Brazil (3°12'47.82"S, 60°35'55.32"W). The T3 GoAmazon site varies between sampling strictly pristine (biogenic) emissions and influence from anthropogenic emissions from Manaus, depending on meteorological conditions. Here we present overall trends and regimes observed during the campaign, with a focus on HCHO, CHOCHO, and related species within the context of VOC oxidation and secondary pollutant production.

Do hip muscle weakness and dynamic knee valgus matter for the clinical evaluation and decision-making process in patients with patellofemoral pain?

PubMed

Rabelo, Nayra Deise Dos Anjos; Lucareli, Paulo Roberto Garcia

Patellofemoral pain is a very common musculoskeletal condition. In the last years, evidence regarding this disease increased exponentially. Although widely investigated, this problem still frustrates patients and clinicians for having an unfavorable prognosis. Some gaps still exist in the understanding and managing of patellofemoral pain. Numerous cross-sectional association studies show an association between gluteus muscular strength and dynamic knee valgus in patients with patellofemoral pain. In spite of this biological plausibility, many evidences challenge the direct relationship between these factors. Recent studies have concluded that women with patellofemoral pain show muscular weakness of the hip based on the cross-sectional studies, however prospective studies indicate that hip weakness cannot be considered a risk for development of patellofemoral pain. In addition, some clinical trials have demonstrated that strength training of the gluteal muscles promotes significant improvement in symptoms but not alter the kinematics of the patients with patellofemoral pain. These findings cast doubt on whether the cause of this condition is really being treated, whether all individuals suffering from patellofemoral pain present dynamic knee valgus or if this is a disturbance present in only a subgroup of patients and whether the strengthening of the hip musculature is an option to consider for prevention of patellofemoral pain. Certainly, more studies should be conducted to clarify the influence of mechanical patterns on this condition, but with the existing evidence so far, the importance given to these issues in the evaluation and clinical decision on treatment of these patients seems questionable. Therefore, this masterclass explores the understanding about patellofemoral pain, highlighting mainly the importance of muscular strength and dynamic knee valgus, as well as other possible factors that must be consider during the evaluation and the decision making in these patients.

To characterize the current stage of the institutionalization of pharmaceutical services in Brazilian cities. This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a cross-sectional, exploratory, and evaluative study composed by an information survey in a representative sample of cities, stratified by Brazilian regions. We interviewed municipal secretaries of health, responsible for pharmaceutical services, and pharmacists responsible for the dispensing of medicines. The variables selected from the interviews were grouped into five dimensions that defined three stages of pharmaceutical services institutionalization: incipient (0%-34.0%), partial (35.0%-69.0%), and advanced (70.0%-100%), estimated based on the interviewees' answers. Frequencies were estimated with 95% confidence intervals. For the statistical association analysis, the Chi-square test was applied, with significance level of p<0.05. Our results show a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazil, and an advanced stage in formal structures, such as the municipal health plans and the existence of a standardized list of medicines. The analysed variables in the "organization, structure, and financing" dimension configured stages that range from partial to advanced. The management presented partial institutionalization, positively showing the existence of computerized system, but also disparate results regarding the autonomy in the management of financial resources. Indispensable items related to the structure expressed disparities between the regions, with statistically significant differences. The study showed a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazilian cities, showing regional disparities. Variables related to the normative aspects of institutionalization were positively highlighted in all dimensions; however, it is necessary to conduct new studies to evaluate the institutionalization of pharmaceutical services' finalistic activities.

To characterize the infrastructure of the primary health care pharmacies of the Brazilian Unified Health System, aiming at humanizing the offered services. This is a cross-sectional study, of quantitative approach, from data obtained in the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). Information on 1,175 pharmacies/dispensing units were gathered from direct observation and assessment of dispensing units installations conducted by trained researchers who used a standardized form. The analyzed variables refer to the physical structure of pharmacies or medicine dispensing units of the health units under research. The pharmacy area was greater than 14 m2 in 40.3% of the sampled units, highlighting those from Midwest (56.9%) and Southeast (56.2%) regions and those of Northeast, with only 23.3%. About 80.2% units had waiting rooms with chairs for patients, 31.8% of them had dispensing areas inferior to 5m2, while in 46.2% these areas were superior to 10m2. Bars were found in service counters in 23.8% of health units, thus separating the patient from the professional; 44.1% had internet access. In most units, the area of medicine storage had no refrigerator or freezer for their exclusive storage and 13.7% had a specific room for pharmaceutical consultation. Aiming at achieving care humanization and improving working conditions for professionals, the structuring of the environment of pharmacy services is necessary. This would contribute to the better qualification of pharmacy services, comprising more than medicine delivery. Data on the Northeast region indicated less favorable conditions to the development of adequate dispensing services. Based on the panorama pointed out, we suggest the expansion of stimulus concerning the physical structure of pharmaceutical services, considering regional specificities.

There are very few observational methods for analysis of biomechanical exposure available in Brazilian-Portuguese. This study aimed to cross-culturally adapt and test the measurement properties of the Rapid Upper Limb Assessment (RULA) and Strain Index (SI). The cross-cultural adaptation and measurement properties test were established according to Beaton et al. and COSMIN guidelines, respectively. Several tasks that required static posture and/or repetitive motion of upper limbs were evaluated (n>100). The intra-raters' reliability for the RULA ranged from poor to almost perfect (k: 0.00-0.93), and SI from poor to excellent (ICC 2.1 : 0.05-0.99). The inter-raters' reliability was very poor for RULA (k: -0.12 to 0.13) and ranged from very poor to moderate for SI (ICC 2.1 : 0.00-0.53). The agreement was good for RULA (75-100% intra-raters, and 42.24-100% inter-raters) and to SI (EPM: -1.03% to 1.97%; intra-raters, and -0.17% to 1.51% inter-raters). The internal consistency was appropriate for RULA (α=0.88), and low for SI (α=0.65). Moderate construct validity were observed between RULA and SI, in wrist/hand-wrist posture (rho: 0.61) and strength/intensity of exertion (rho: 0.39). The adapted versions of the RULA and SI presented semantic and cultural equivalence for the Brazilian Portuguese. The RULA and SI had reliability estimates ranged from very poor to almost perfect. The internal consistency for RULA was better than the SI. The correlation between methods was moderate only of muscle request/movement repetition. Previous training is mandatory to use of observations methods for biomechanical exposure assessment, although it does not guarantee good reproducibility of these measures.

Short-term results of the bioprosthetic Biocor No-React composite porcine stentless aortic valve (Biocor Industria e Pesquisas LTDA, Belo Horizonte, Brazil) implanted in patients in whom anticoagulation was thought to be contraindicated or expected to be non-compliant. Retrospective review of 52 consecutive prospective patients in whom this valve was implanted, between September 1994 and May 1998. Average age was 44 +/- 17 years; 75% of patients were operated on for rheumatic heart disease and combined procedures were done in 40% of cases. Early mortality was 5.8%, and related to pre-operative ejection fraction ( P < 0.03), New York Heart Association (NYHA) class (P < 0.01), and bacterial endocarditis (P < 0.04). On discharge, 84% of survivors were in NYHA class I and 16% in class II. The average postoperative prosthetic valve peak gradient on echocardiography was 19.9 +/- 11 mmHg and was related to pre-operative ejection fraction and smaller valve sizes. Postoperative residual trivial or mild aortic regurgitation was seen in 19 patients (36.6%), resolved on follow-up in 10 cases, and did not correlate with structural deterioration, re-operation, mortality, or widening of the non-coronary sinus. The non-coronary aortic sinus was widened on closure, because of perceived crowding of the adjacent stentless valve commisures, in 52% of cases. This was thought to be related to the use of an oblique as opposed to transverse aortotomy. Patient survival, inclusive of operative deaths, was 88.5%, and event-free survival was 80.0% at 4 years. The short-term results of this stentless aortic valve in a young predominantly third-world population group are acceptable, and appear to be superior to the results for mechanical valves in a similar patient group. We would recommend a transverse aortotomy above the sinotubular ridge to be the more appropriate aortotomy incision when using stentless aortic valves.

The Iconographical Falls Efficacy Scale (Icon-FES) is an innovative tool to assess concern of falling that uses pictures as visual cues to provide more complete environmental contexts. Advantages of Icon-FES over previous scales include the addition of more demanding balance-related activities, ability to assess concern about falling in highly functioning older people, and its normal distribution. To perform a cross-cultural adaptation and to assess the measurement properties of the 30-item and 10-item Icon-FES in a community-dwelling Brazilian older population. The cross-cultural adaptation followed the recommendations of international guidelines. We evaluated the measurement properties (i.e. internal consistency, test-retest reproducibility, standard error of the measurement, minimal detectable change, construct validity, ceiling/floor effect, data distribution and discriminative validity), in 100 community-dwelling people aged ≥60 years. The 30-item and 10-item Icon-FES-Brazil showed good internal consistency (alpha and omega >0.70) and excellent intra-rater reproducibility (ICC 2,1 =0.96 and 0.93, respectively). According to the standard error of the measurement and minimal detectable change, the magnitude of change needed to exceed the measurement error and variability were 7.2 and 3.4 points for the 30-item and 10-item Icon-FES, respectively. We observed an excellent correlation between both versions of the Icon-FES and Falls Efficacy Scale - International (rho=0.83, p<0.001 [30-item version]; 0.76, p<0.001 [10-item version]). Icon-FES versions showed normal distribution, no floor/ceiling effects and were able to discriminate between groups relating to fall risk factors. Icon-FES-Brazil is a semantically and linguistically appropriate tool with acceptable measurement properties to evaluate concern about falling among the community-dwelling older population.

Objective To investigate the social impact of literacy on the smoking behavior of illiterate individuals who share the household with literate individuals. Method This cross-sectional study employed data from the 2008 Brazilian National Household Survey (Pesquisa Nacional por Amostra de Domicílios, PNAD). Smokers were defined as individuals reporting use of any tobacco product daily or less than daily. The literacy profiles of residents were identified. Poisson regressions adjusted for skin color, age, and maximum level of literacy in the household were performed. Four groups were analyzed: men living in rural areas, men living in urban areas, women living in rural areas, and women living in urban areas. Results For urban men, the presence of literate women only in the household was a protection factor against smoking (prevalence ratio, PR: 0.77; 95%CI: 0.71-0.82) vs. households in which all the males were illiterate. The same protective effect was found for rural men (PR: 0.79; 95%CI: 0.73-0.85). In turn, the presence of literate men only living in the same household with illiterate men did not provide protection against smoking in any case (PR: 0.93; 95%CI: 0.83-1.03 for the urban subsample; and PR: 0.99; 95%CI: 0.88-1.11 for the rural subsample). Illiterate women benefited from the presence of both literate men (PR: 0.77; 95%CI: 0.71-0.84 for the urban sample; and PR: 0.78; 95%CI: 0.69-0.89 for the rural subsample) and literate women (PR: 0.81; 95%CI: 0.72-0.92 for the urban subsample; and PR: 0.75; IC95%: 0.60-0.93 for the rural subsample). Conclusions Literate women seem to have positively affected illiterate co-residents of both sexes. This result is in agreement with reports showing broad advantages of female schooling.

The research aimed to identify the current feed of Xerente people in Indian villages Porteira and Funil in the city of Tocantinia / TO. It was used a qualitative ethnographic approach. Conducted from September 2013 to August 2014. The data were presented in a diary, through participant observation of food practices with the guidance of a script. A process of dietary change that permeates the culture of this people is taking place. Factors such as the deficit in the planting gardens, the recent arrival of energy, and therefore the technology has allowed access to processed foods. But some families still maintain the farming of cassava, yam, and beans. The main animals that are hunted in the village are peccary, deer and armadillo. It was possible to point which foods are inserted in the Xerente feed and factors related to this situation. A pesquisa objetivou identificar a alimentação atual do povo Xerente, nas aldeias indígenas Porteira e Funil, no município de Tocantínia / TO. Utilizou-se uma abordagem etnográfica qualitativa. Realizada entre setembro de 2013 a agosto de 2014. Os dados foram descritos através de um diário de campo, por meio da observação das práticas alimentares com a orientação de um roteiro. Está ocorrendo um processo de mudança alimentar na cultura deste povo. Fatores como o déficit no plantio das roças, a chegada da energia, e consequentemente a tecnologia, permitiu o acesso a alimentos industrializados. Mas algumas famílias ainda mantem o cultivo de mandioca, inhame, feijão andu. Os principais animais que são caçados na aldeia são caititu, veado e tatu. Foi possível encontrar a presença de alimentos industrializados inseridos na alimentação do Xerente e isso tem provocado alterações nos hábitos desse povo.

To identify scientific evidence regarding the influence of hormonal contraceptive use and the occurrence of stroke. Integrative review of the literature, through database search using the descriptors "contraceptive agents", "contraceptive devices", "contraceptives, Oral" and "Stroke". Original studies in Portuguese, Spanish and English, published in full and available online were included. Studies that did not answer our guiding questions and duplicated studies were excluded. Women using combined oral contraceptives have higher risk of stroke, even with a lower hormonal dosage and different types of progestogen, regardless of the duration of use. The use of contraceptives associated with smoking, hypertension, migraine, hypercholesterolemia, obesity and sedentary lifestyle increases the chance of stroke. Contraceptive patch and vaginal ring are associated to increased risk. Use of combined hormonal contraceptives, except for the injectable and the transdermal ones, increases the chance of occurrence of the event. Progestogen-only contraceptives were considered safe. Identificar evidências científicas acerca da influência do uso de anticoncepcionais hormonais na ocorrência do acidente vascular cerebral (AVC). Revisão integrativa da literatura, com pesquisa em bases de dados, utilizando os descritores "contraceptive agents", "contraceptive devices", "contraceptives, Oral" e "stroke". Foram incluídos artigos originais nos idiomas português, espanhol e inglês, publicados na íntegra e disponíveis eletronicamente. Foram excluídos artigos que não respondiam às questões norteadoras e repetidos. Usuárias de anticoncepcional oral combinado apresentam risco maior de AVC, mesmo com dosagem hormonal menor e diferentes tipos de progestágeno, independente do tempo de uso. A presença associada de tabagismo, hipertensão arterial, enxaqueca, hipercolesterolemia, obesidade e sedentarismo aumenta a chance desse desfecho. Adesivo anticoncepcional e anel vaginal são relacionados ao aumento desse risco. A exposição aos anticoncepcionais hormonais combinados aumenta a chance de ocorrência do evento, exceto o injetável e o transdérmico. Os exclusivos de progestágeno foram considerados seguros.

ABSTRACT OBJECTIVE To characterize the current stage of the institutionalization of pharmaceutical services in Brazilian cities. METHODS This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), a cross-sectional, exploratory, and evaluative study composed by an information survey in a representative sample of cities, stratified by Brazilian regions. We interviewed municipal secretaries of health, responsible for pharmaceutical services, and pharmacists responsible for the dispensing of medicines. The variables selected from the interviews were grouped into five dimensions that defined three stages of pharmaceutical services institutionalization: incipient (0%-34.0%), partial (35.0%-69.0%), and advanced (70.0%-100%), estimated based on the interviewees’ answers. Frequencies were estimated with 95% confidence intervals. For the statistical association analysis, the Chi-square test was applied, with significance level of p<0.05. RESULTS Our results show a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazil, and an advanced stage in formal structures, such as the municipal health plans and the existence of a standardized list of medicines. The analysed variables in the “organization, structure, and financing” dimension configured stages that range from partial to advanced. The management presented partial institutionalization, positively showing the existence of computerized system, but also disparate results regarding the autonomy in the management of financial resources. Indispensable items related to the structure expressed disparities between the regions, with statistically significant differences. CONCLUSION The study showed a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazilian cities, showing regional disparities. Variables related to the normative aspects of institutionalization were positively highlighted in all dimensions; however, it is necessary to conduct new studies to evaluate the institutionalization of pharmaceutical services’ finalistic activities.

ABSTRACT OBJECTIVE To identify and discuss the conceptions of pharmaceutical services in Brazilian Primary Health Care, according to different subjects. METHODS This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015), which is composed of an information survey in a representative sample of cities, stratified according to Brazilian regions, and a subsample of primary health care services. Municipal secretaries of health, those responsible for pharmaceutical services, and those responsible for medicine delivery in pharmacies/dispensing units of the selected services were interviewed. The questionnaires included one question about the understanding of the interviewee regarding pharmaceutical services. The content analysis technique was used to apprehend, in the statements, the meanings attributed to pharmaceutical services, which were subsequently classified into categories according to their main conceptions. RESULTS Among the wide diversity of conceptions on pharmaceutical services (PS), we highlight the ones focused on 1) logistic control of medicines with activities concerning guidance or information on their use and 2) guidance or information to users on the use of medicine. The findings reveal a shifting tendency from a medicine-focused conception to one that considers the users and their needs as the final recipient of these actions. However, the lack of references to conceptions regarding care management and integrality point out the slowness of this change; after all, this is a social and historical process that comprises the production of meanings that transcend legal, logistic, and technical arrangements in pharmaceutical services. CONCLUSIONS The diversity of conceptions expresses the several meanings attributed to pharmaceutical services; we also identified, in their reorientation process, a movement that reflects a gradual shift in the technical paradigm, from the focus on medicine logistics to a user-oriented approach of health services.

A pesquisa sobre remanescentes de aglomerados abertos tem despertado grande interesse. Seguindo esta tendência encontramos estudos teóricos e observacionais. Os primeiros baseiam-se em simulações numéricas buscando determinar fração de binárias e distâncias galatocêntricas, tempo de vida e conteúdo estelar. Estes estão relacionados à função inicial de massa e densidade de estrelas, ou seja, se ricos ou pobremente povoados, compactos ou esparsos. No caso observacional procuram-se identificar os remanescentes considerando-se que trazem estas assinaturas de seus percursores. No presente estudo empregamos espectroscopia para analisar oito concentrações pobremente povoadas, previamente classificadas como aglomerados abertos, sendo sete compactas e uma esparsa. As observações foram obtidas através do telescópio de 2,15 m do CASLEO em San Juan, Argentina, em turnos entre 2001 e 2003. Utilizamos uma câmara CCD contendo um chip Tektronics de 1024X1024 pixeis aliado a um espectrógrafo REOSC. O domínio espectral vai de 3700 a 7000 Å. As reduções foram realizadas no Observatório Astronômico de Córdoba (Argentina) usando pacotes IRAF padrões. Determinamos idades, avermelhamentos e tipos espectrais através de comparações com biblioteca de estrelas e de aglomerados. Em alguns casos nossos espectros estavam dominados por estrelas individuais às quais determinamos seus tipos espectrais. Aos oito objetos adicionamos mais cinco da literatura recente analisados via espectro ou diagrama cor-magnitude. O histograma resultante contém idades típicas entre 0.5 e 3 Ganos. Considerando que predominantemente estes objetos encontram-se na vizinhança solar e, portanto, não cruzaram muitas vezes o plano Galático esperamos que a diferença no tempo necessário para dissolução destes prováveis remanescentes seja em função de diferentes massas iniciais.

A dual-task tool with a challenging and daily secondary task, which involves executive functions, could facilitate the screening for risk of falls in older people with mild cognitive impairment or mild Alzheimer's disease. To verify if a motor-cognitive dual-task test could predict falls in older people with mild cognitive impairment or mild Alzheimer's disease, and to establish cutoff scores for the tool for both groups. A prospective study was conducted with community-dwelling older adults, including 40 with mild cognitive impairment and 38 with mild Alzheimer's disease. The dual-task test consisted of the Timed up and Go Test associated with a motor-cognitive task using a phone to call. Falls were recorded during six months by calendar and monthly telephone calls and the participants were categorized as fallers or non-fallers. In the Mild cognitive impairment Group, fallers presented higher values in time (35.2s), number of steps (33.7 steps) and motor task cost (116%) on dual-task compared to non-fallers. Time, number of steps and motor task cost were significantly associated with falls in people with mild cognitive impairment. Multivariate analysis identified higher number of steps spent on the test to be independently associated with falls. A time greater than 23.88s (sensitivity=80%; specificity=61%) and a number of steps over 29.50 (sensitivity=65%; specificity=83%) indicated prediction of risk of falls in the Mild cognitive impairment Group. Among people with Alzheimer's disease, no differences in dual-task between fallers and non-fallers were found and no variable of the tool was able to predict falls. The dual-task predicts falls only in older people with mild cognitive impairment. Copyright © 2018 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

ABSTRACT OBJECTIVE To characterize the technical issues and conditions of medicines conservation in Primary Health Care of Brazilian regions, responsible for pharmacy/dispensing unit profile; environmental, storage, and dose fractioning conditions; inventory control and waste management; fire and electrical failure safety items; transportation problems; advertising regulation; and pharmacovigilance. METHODS This article is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços (National Survey on Access, Use and Promotion of Rational Use of Medicines – Services)–, a cross-sectional and exploratory study, of evaluative nature, consisting of an information survey within a representative sample of municipalities, stratified by Brazilian regions, which constitute the study domains, and a sample of Primary Health Care services. Pharmaceutical services (PS) were directly observed with photographic record and face-to-face interviews with those responsible for the dispensing of medicines and over the telephone with those responsible for pharmaceutical services. Data were processed with the SPSS® software version 21. RESULTS The investigated dimensions showed relevant deficiencies and inequalities between the regions, generally more favorable in the Southeast and Midwest regions and weaker in the Northeast and North regions. We verified non-compliance with technical requirements and conditions essential to the conservation of medicines, which may interfere with the maintenance of stability and, thus, on their quality, efficacy, and safety. The regulation of advertising/promotion of medicines is still incipient and there is some progress in the structuring of mechanisms regarding pharmacovigilance. CONCLUSIONS The sanitary situation of medicines in Brazilian Primary Health Care is alarming due to the violation of the specific sanitary legislation for dispensing establishments and due to a wide range of requirements essential to the conservation of medicines. We observed a disconnection between the efforts made in the Brazilian Unified Health System to promote access to medicines for all population and the organization and qualification of pharmaceutical services.

Physical exercise has been used to mitigate the metabolic effects of diabetes mellitus. To evaluate the effect of resistance exercise when compared to aerobic exercise without insulin therapy on metabolic and clinical outcomes in patients with type 2 diabetes mellitus. Papers were searched on the databases MEDLINE/PubMed, CINAHL, SPORTDiscus, LILACS, and SCIELO, without language or date of publication limits. Clinical trials that compared resistance exercise to aerobic exercise in adults with type 2 diabetes mellitus who did not use insulin therapy were included. The quality of evidence and risk of bias were assessed using the GRADE system and the Cochrane Risk of Bias tool, respectively. Meta-analysis was also used, whenever possible. Two reviewers extracted the data independently. Eight eligible articles were included in this study, with a total of 336 individuals, with a mean age of 48-58 years. The protocols of aerobic and resistance exercise varied in duration from eight to 22 weeks, 30-60min/day, three to five times/week. Overall the available evidence came from a very low quality of evidence and there was an increase in Maximal oxygen consumption (mean difference: -2.86; 95% CI: -3.90 to -1.81; random effect) for the resistance exercise and no difference was found in Glycated hemoglobin, Body mass index, High-density lipoprotein cholesterol, Low-density lipoprotein cholesterol, triglycerides, and total cholesterol. Resistance exercise appears to be more effective in promoting an increase in Maximal oxygen consumption in protocols longer than 12 weeks and there is no difference in the control of glycemic and lipid levels between the two types of exercise.

ABSTRACT OBJECTIVE This study aims to describe the places of purchase of food consumed outside the home, characterize consumers according to the places of consumption, and identify the food purchased by place of consumption in Brazil. METHODS We have used data from the Pesquisa de Orçamento Familiar (Household Budget Survey) of 2008-2009 with a sample of 152,895 subjects over 10 years of age. The purchase of food outside the home was collected from the records of all expenditures made in seven days. The places of purchase were grouped according to their characteristics: supermarket, bakery, street food, restaurant, snack bar, fruit shop, and other places. The types of food were grouped into nine categories, considering the nutritional aspects and the marketing characteristics of the item. We have estimated the frequency of purchase in the seven groups of places in Brazil and according to gender and type of food purchased per place. We have calculated the average age, income and years of education, as well as the per capita expenditure according to places of purchase of food consumed outside the home. RESULTS The purchase of food outside the home was reported by 41.2% of the subjects, being it greater among men than women (44% versus 38.5%). Adults had a higher frequency (46%) than teenagers (37.7%) and older adults (24.2%). The highest frequency of places of purchase were snack bar (16.9%) and restaurant (16.4%), while the fruit shop (1.2%) presented the lowest frequency. Sweets, snack chips and soft drinks were the most purchased items in most places. Average expenditure was higher for restaurant (R$33.20) and lower for fruit shop (R$4.10) and street food (R$5.00). CONCLUSIONS The highest percentage of food consumed outside the home comes from snack bars and restaurants, pointing to important places for the development of public policies focused on promoting healthy eating.

Beryllium-7 (T1/2 = 53.3 days), a cosmogenic radionuclide produced continuosly in the upper atmosphere by cosmic ray spallation reactions with oxygen and nitrogen can be found in different compartments of the environment and its concentration is influenced by several factors, such as, temperature, precipitation, air velocity, air masses, altitude and as well as latitude. It is quickly attached to aerosols after its formation, becoming a useful tool to study the dynamics of aerosol particles in the atmosphere. Long-term measurements of the spatial and temporal variation of 7Be allows assessment of the influence of these factors. Data of 7Be concentrations in rainfall, air surface, soil and sediments are very well reported in Northern Hemisphere; however these same results are limited in Southern Hemisphere. During a period of 13 years, from October 2001 to October 2014, 7Be concentration was measured every 15 days in surface air at Instituto de Pesquisas Energéticas e Nucleares (IPEN), in the city of São Paulo, São Paulo, Brazil. IPEN campus is located approximately 10 km west from downtown of the city of São Paulo, which is situated on a plateau in Southeastern Brazil, at latitude 23°33'58.27"S and longitude 46°44'14.82"W and an average altitude of 760m above sea level. The climate in the area is temperate tropical with dry period in winter and rainy in summer. The concentrations of 7Be in air filters were measured by non-destructive g-ray spectrometry using a coaxial Be-layer HPGe detector with 15% relative efficiency and live counting time ranged from 100,000s to 250,000 s. The results obtained were correlated to seasons, rainfall, temperature and sunspot number. The concentrations displayed clearly seasonal variations with higher values in spring and summer time and with the amount of precipitation.

High blood pressure is strongly associated with obesity in different populations. However, it is unclear whether different anthropometric indicators of obesity can satisfactorily predict high blood pressure in the school setting. This study evaluated the sensitivity and specificity of body mass index, waist circumference, and waist to height ratio in the detection of high blood pressure in adolescents. The sample consisted of 8295 adolescents aged 10-17 years. Weight was measured using a digital scale, height with a stadiometer, and waist circumference using a tape measure. Blood pressure was measured by an automatic blood pressure measuring device. ROC curves were used for the analysis of sensitivity and specificity of the three anthropometric indices in identifying high blood pressure. Binary Logistic Regression was used to assess the association of body mass index, waist circumference, and waist to height ratio with high blood pressure. Low values of sensitivity were observed for body mass index (0.35), waist circumference (0.37), and waist to height ratio (0.31) and high values of specificity for body mass index (0.86), waist circumference (0.82), and waist to height ratio (0.83) in the detection of high blood pressure. An association was observed between adolescents classified with high body mass index (OR=3.57 [95% CI=3.10-4.10]), waist cirumference (OR=3.24 [95% CI=2.83-3.72]), and waist to height ratio (OR=2.94 [95% CI=2.54-3.40]) with high blood pressure. Body mass index, waist circumference, and waist to height ratio presented low sensitivity to identify adolescents with high blood pressure. However, adolescents classified with high body mass index, waist circumference, and waist to height ratio demonstrated a high association of presenting high blood pressure.

Respiratory muscle training has shown to increase strength of the respiratory muscles following a stroke. However, low duration and/or intensity of training may be responsible for the small effect size seen and/or absence of carry-over effects to an activity, e.g., walking. Therefore, an investigation of the effects of long-duration, high-intensity respiratory muscle training is warranted. This proposed protocol for a randomized clinical trial will examine the efficacy of high-intensity respiratory muscle training to increase strength and improve activity following a stroke. This study will be a two-arm, prospectively registered, randomized controlled trial, with blinded assessors. Thirty-eight individuals who have suffered a stroke will participate. The experimental group will undertake a 40-min of respiratory muscle training program, seven days/week, for eight weeks in their homes. Training loads will be increased weekly. The control group will undertake a sham respiratory muscle training program with equivalent duration and scheduling of training. The primary outcome will be the strength of the inspiratory muscles, measured as maximal inspiratory pressure. Secondary outcomes will include expiratory muscle strength, inspiratory muscle endurance, dyspnea, respiratory complications, and walking capacity. Outcomes will be collected by a researcher blinded to group allocation at baseline (Week 0), after intervention (Week 8), and one month beyond intervention (Week 12). High-intensity respiratory muscle training may have the potential to optimize the strength of the respiratory muscles following a stroke. If benefits are carried over to activity, the findings may have broader implications, since walking capacity has been shown to predict physical activity and community participation on this population.

OBJECTIVE To analyze oral health behaviors changes over time in Brazilian adolescents concerning maternal educational inequalities. METHODS Data from the Pesquisa Nacional de Saúde do Escolar (Brazilian National School Health Survey) were analyzed. The sample was composed of 60,973 and 61,145 students from 26 Brazilian state capitals and the Federal District in 2009 and 2012, respectively. The analyzed factors were oral health behaviors (toothbrushing frequency, sweets consumption, soft drink consumption, and cigarette experimentation) and sociodemographics (age, sex, race, type of school and maternal schooling). Oral health behaviors and sociodemographic factors in the two years were compared (Rao-Scott test) and relative and absolute measures of socioeconomic inequalities in health were estimated (slope index of inequality and relative concentration index), using maternal education as a socioeconomic indicator, expressed in number of years of study (> 11; 9-11; ≤ 8). RESULTS Results from 2012, when compared with those from 2009, for all maternal education categories, showed that the proportion of people with low toothbrushing frequency increased, and that consumption of sweets and soft drinks and cigarette experimentation decreased. In private schools, positive slope index of inequality and relative concentration index indicated higher soft drink consumption in 2012 and higher cigarette experimentation in both years among students who reported greater maternal schooling, with no significant change in inequalities. In public schools, negative slope index of inequality and relative concentration index indicated higher soft drink consumption among students who reported lower maternal schooling in both years, with no significant change overtime. The positive relative concentration index indicated inequality in 2009 for cigarette experimentation, with a higher prevalence among students who reported greater maternal schooling. There were no inequalities for toothbrushing frequency or sweets consumption. CONCLUSIONS There were changes in the prevalences of oral health behaviors during the analyzed period; however, these changes were not related to maternal education inequalities. PMID:26270015

Pesquisa qualitativa e descritiva, tendo como cenário um hospital universitário. Os participantes foram 34 trabalhadores de enfermagem. A coleta ocorreu de março a julho de 2013, por meio de entrevista semiestruturada. A técnica de tratamento dos dados foi a análise de conteúdo, que fez emergir a seguinte categoria: precarização das condições laborais e suas repercussões para organização e processo de trabalho hospitalar no contexto neoliberal. Evidenciaram-se repercussões do neoliberalismo na organização e no processo de trabalho hospitalar, verificando-se inadequações na estrutura física, nos recursos humanos e materiais, que afetavam a qualidade da assistência. Além de perdas salariais que levam à necessidade de outros empregos e sobrecarga de trabalho. Há forte influência do modelo neoliberal no trabalho hospitalar, resultando na precarização das condições laborais.

To understand mental health nursing care based on the concept of the subject of the unconscious proposed by Lacan. A narrative study was carried out with 19 nurses, chosen based on their theoretical approach or referral by other participants, through the snowball sampling technique. The interviews were carried out in person or digitally, and were recorded and fully transcribed. The analysis was carried out based on Freudian and Lacanian psychoanalysis, approaching nursing care as it acts on the body, secretions, and excretions, to distinguish it from the spirit of fineness. Effects on care are discussed, considering the subject of the unconscious with its knowledge, creating unique exits (sinthome). In this situation, professionals are required to abstain from a position of knowing what is better for the Other. This nursing care perspective offers contributions when discussing the centrality of the subject and words in the care process. Compreender o cuidado de enfermagem em saúde mental a partir da concepção de sujeito do inconsciente proposta por Lacan. Pesquisa narrativa, realizada com 19 enfermeiros, determinados por meio de abordagem teórica ou indicação de outro participante, pela técnica de snowball. As entrevistas foram realizadas pessoalmente ou por meio digital, gravadas e transcritas na íntegra. Da análise, fundamentada na psicanálise freudiana e lacaniana, tomou-se o cuidado de enfermagem em seus atos sobre o corpo, suas secreções e excreções, para localizá-lo a partir do espírito de fineza. Discutem-se os efeitos para o cuidado quando se considera o sujeito do inconsciente com seu saber construindo saídas únicas - Sinthoma. Essa condição requer do profissional abster-se de uma posição de saber o que é melhor para o outro. Essa perspectiva de cuidado de enfermagem traz contribuições ao problematizar a centralidade do sujeito e da palavra nas práticas de cuidado.

ABSTRACT OBJECTIVE To analyze the prevalence of medicine use by the Brazilian population and its distribution according to sociodemographic factors. METHODS Study using data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide household survey of a representative sample of the Brazilian urban population. The data were collected between September 2013 and February 2014. The overall use of medicines, defined as the use of any medicine, use of medicines for treating chronic medical conditions and for acute health conditions, was evaluated. The independent variables included gender, age group, socioeconomic position, and region of Brazil. Analyzes included prevalence calculations, 95% confidence intervals (95%CI) and Pearson Chi-square tests to evaluate the differences between groups, considering a 5% level of significance. RESULTS The prevalence of medicines use was 50.7% (95%CI 49.3–52.2), with 39.3% (95%CI 37.5–41.1) accounting for men and 61.0% (95%CI 59.3–62.6) for women. Medicines use was observed to increase with increasing age, except among children within the zero to four years age group. The lowest prevalence for medicines use was found among those with a low socioeconomic position and those who reside in the North region of Brazil. The prevalence of medicine use to treat chronic diseases was 24.3% (95%CI 23.3–25.4), whereas it was 33.7% (95%CI 32.1–35.4) for treating acute diseases. CONCLUSIONS We found extensive variability in the prevalence of medicines use across regions of Brazil. The poorest regions (North, Northeast, and Midwest) have a lower prevalence of medicines use to treat chronic diseases, indicating the need to minimize inequalities in access to medicines within the country.

A Radiação Cósmica de Fundo em Microondas (RCFM), descoberta por Penzias e Wilson em 1965, é uma das ferramentas mais poderosas para o estudo da cosmologia. Com a descoberta de flutuações de temperatura na RCFM, da ordem de uma parte em 105, pelo COBE (1992), uma nova era teve início. Nos últimos onze anos, diversos instrumentos fizeram novas medidas de alta precisão, refinando os resultados apresentados pelo COBE, culminando com os resultados recentes do satélite WMAP. A análise de dados da RCFM, especialmente no caso de experimentos com pequena cobertura do céu, apresenta uma série de dificuldades devido a emissões de contaminantes externos, tais como a emissão da Galáxia e de fontes pontuais, e de ruídos intrínsecos tanto ao sistema de detecção quanto à estratégia de observação do céu. Uma das soluções típicas para a filtragem de dados brutos de um experimento para medir flutuações de temperatura é aplicar um gabarito (template) e um filtro passa alta ao produzir mapas simplificados (sem considerar matrizes de correlação ou covariância). No caso de experimentos que utilizam detectores HEMT, essa combinação de filtros remove, satisfatoriamente, ruídos do tipo 1/f gerados pela instabilidade no ganho do detector acoplado ao movimento do instrumento, definido pela estratégia de observação. Entretanto, o sinal resultante medido, tanto em simulações quanto em séries temporais reais, sugere que parte do sinal cosmológico pode estar sendo removido junto com o ruído dos detectores. Este trabalho descreve as etapas para a produção de um mapa típico (simulado) e os testes preliminares de um algoritmo para remover ruídos do tipo 1/f introduzidos pela estratégia de observação sem prejudicar a qualidade do sinal cosmológico presente no mapa.

Analisis experimental de la propagacion en redes de area corporal para la banda de ultra wideband. experimental characterization of the propagation in ultra wideband body area networks

Garcia Serna, Ruben Gregorio

Diferentes dispositivos capaces de obtener informacion sobre parametros fisiologicos, cinematicos o contextuales del cuerpo pueden interconectarse de manera inalambrica dando lugar a las denominadas Redes de Area Corporal Inalambricas (WBAN, Wireless Body Area Networks). De entre las posibles tecnologias para establecer los enlaces, Ultra Wideband (UWB) esta captando cada vez un mayor interes debido a caracteristicas tales como el bajo nivel de potencia de transmision requerido (bajo nivel de exposicion a campos electromagneticos), el alto ancho de banda disponible y la alta resolucion temporal/espacial. El diseno de sistemas centrados en el cuerpo requiere de modelos de canal que describan de manera precisa la propagacion de senales en este tipo de entornos. Esta tesis se plantea con el objetivo de contribuir al estudio experimental de la propagacion en sistemas centrados en el cuerpo operando en la banda UWB. En primer lugar, se presenta un marco introductorio a las redes WBAN, sus elementos constitutivos, bandas de frecuencia, estandarizacion y modelos de canal. Ademas, se introducen los fundamentos de la tecnologia UWB y sus aplicaciones en este area. Seguidamente, se analiza en terminos de las perdidas de propagacion y la dispersion de retardo la propagacion en el canal off-body entre un transmisor fijo y un dispositivo receptor colocado sobre la superficie del cuerpo de un sujeto. Se considera la influencia de diferentes aspectos, tales como el entorno de medidas, la posicion de colocacion de una antena sobre el cuerpo y la postura adoptada por un sujeto. Finalmente, se analiza el canal de propagacion in-body considerando el movimiento relativo entre dos dispositivos causado por efecto de la respiracion. Las condiciones de propagacion en el interior del cuerpo se emulan por medio de un phantom liquido para UWB y la caracterizacion se plantea tanto en frecuencia, en terminos del modelado de la forma y el ensanchamiento del espectro Doppler, como en tiempo, por medio del estudio de la funcion de autocorrelacion y el tiempo de coherencia del canal.

Introducción: la malnutrición en el anciano que ingresa en el hospital es bastante frecuente y condiciona no solo la extensión de la estancia hospitalaria, sino el pronóstico o la aparición de otras patologías. Su valoración puede basarse en medidas antropométricas, parámetros bioquímicosy test nutricionales.Objetivos: valorar si la circunferencia de pantorrilla es un indicador válido de desnutrición en el paciente anciano recién hospitalizado, analizando la posible influencia del sexo y la edad.Material y métodos: estudio descriptivo en 907 pacientes ancianos pluripatológicos a su ingreso en el hospital, con una edad media de 82,13 ± 7,08 años. Se han realizado determinaciones bioquímicas incluyendo recuento de linfocitos, colesterol total, transferrina y albúmina.Se aplicaron en cada paciente las escalas de cribado nutricional MNA, NRS y VGS. Finalmente se determinó la circunferencia de la pantorrilla.Resultados: los test nutricionales muestran un porcentaje de desnutrición medio del 75%. Los parámetros bioquímicos muestran un porcentaje de desnutrición que oscila del 63,4% al 76,7%, y la circunferencia de la pantorrilla un 74,2%. La prevalencia de desnutrición es mayor en mujeres, independientemente del parámetro utilizado en su determinación. El aumento en la edad, particularmente a partir de los 85 años, y con todos los parámetros analizados, también condiciona un mayor grado de desnutrición. Todos los parámetros estudiados se correlacionan con la circunferencia de la pantorrilla, estableciéndose el concepto "estar desnutrido" en el punto de corte de 29 cm, para ambos sexos y en todos los grupos de edad (sensibilidad 99,31%).Conclusiones: un 75% de la población anciana presenta desnutrición a su ingreso en el hospital. La circunferencia de la pantorrilla es un marcador de desnutrición en el anciano de fácil determinación y alta sensibilidad, independiente del sexo y la edad.

Reacciones de intercambio de carga

NASA Astrophysics Data System (ADS)

Errea, L. F.

Se discute la validez de diversas metodologías y su aplicación al estudio de procesos de intercambio de carga electrónico entre iones y blancos atómicos y moleculares. Para energías de impacto entre 0.05 y 5 eV / amu se emplea el método cuántico de la Coordenada de Reacción Común (CRC). A mayores energías, se utiliza el método semiclásico iconal con un desarrollo de la función de onda dinámica en estados moleculares adiabáticos, modificados con un factor de traslación común (FTC). Estos estados pueden obtenerse con cálculos ab initio o empleando potenciales modelo. Cuando la ionización compite con la transferencia de carga, la inclusión de pseudoestados en estos desarrollos permite calcular simultáneamente las secciones eficaces de ambos procesos. Otra técnica utilizada es el método estadístico CTMC. En el tratamiento de colisiones ión-molécula (diatómica) contrastamos la aplicabilidad de distintos métodos, desde la llamada aproximación Franck-Condon hasta un desarrollo en estados vibrónicos, pasando por la aproximación súbita vibro-rotacional, obteniéndose secciones eficaces de captura electrónica total y a estados individuales, así como secciones de excitación vibracional a estados ligados y del continuo (disociación). En todos los casos es necesario calcular superficies de energía y los correspondientes acoplamientos dinámicos entre los estados. La aplicación de estos métodos permite determinar el grado de contaminación de los haces por estados metaestables en un experimento dado, el cambio en los resultados con diferentes isótopos, la importancia de procesos de doble captura, seguida de explosión culombiana, todo ello con precisión comparable a la de medidas experimentales, para sistemas de interés en distintos tipos de plasmas.

Relaciones hidrogeologicas y medioambientales entre el mar mediterraneo, El saladar y el acuifero de agua amarga (provincia de alicante). Incidencia de las explotaciones de las desaladoras de alicante I Y II Y medidas correctoras

Manteca, Ivan Alhama

The Agua Amarga coastal aquifer, located in the south of Alicante province, has been subjected to successive anthropogenic actions: salt works activity (1925-1975) and water withdrawal to supply the Alicante I and II desalination plants (since 2003). These interventions have influenced the salinity and the flow regime. Due to the existence of a salt marsh of ecological interest linked to the aquifer, the 'Mancomunidad de los Canales del Taibilla' (agency responsible for the desalination plants) designed a piezometric network for monitoring piezometry and electrical conductivity (in operation since May 2008). Soil humidity and piezometrics levels have been recovered by means of a seawater pouring programme over the salt marsh (since December 2009),which represents the third anthropic intervention. In this memoria, we investigate the Agua Amarga coastal aquifer to develop a physical conceptual model. Firstly, the study area is characterized in relation to climatology, geology, geomorphology and hydrogeology, using published information, describing, in addition, the desalination plants catchment system. Next, based on hydrogeological studies prior to the start up of the desalination plants, the aquifer is characterized: type, lithology, hydraulic parameters, thickness, surface extension, etc. Water quantity relating to rainfall, water withdrawal and pourings over the salt marsh, have been integrated in conjunction with data from monthly piezometric campaigns. In adittion, in order to gain insight into the groundwater mixing processes, chemical and isotope analyses were carried out on meteoric water and groundwater samples taken at different locations. The results were used to elaborate a conceptual physical model and a water budget. As an extension tool to understand processes and assess aquifer management, a 3-D fluid-flow and solute-transport model is designed with SEAWAT. Also, the 2-D physical characterization of scenarios with seawater intrusion and salt flats is presented. Finally, after describing ecological values of the salt marsh, the effect of the seawater pouring programme on aquifer piezometry and salinity is studied, assessing the possibility of applying this pilot scheme to other scenarios.

Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disease characterized by the degeneration of motor neurons, which are the central nervous system cells that control voluntary muscle movements. The excessive salivation (sialorrhea) is present in approximately 50% of amyotrophic lateral sclerosis cases. Thus, some alternative therapeutic methods are sought, such as anticholinergic drugs and surgery. Recently the use of botulinum toxin applied at a midpoint of the salivary glands, often guided by ultrasound, have demonstrated positive results. The objective was to review the literature to demonstrate an alternative method to treatments of sialorrhea in patients with amyotrophic lateral sclerosis. In recent studies, the efficacy of botulinum toxin is confirmed, although new applications are required. Since the side effects are negligible, this is an alternative to treat amyotrophic lateral sclerosis, and other patients with diseases that present sialorrhea. RESUMO Esclerose lateral amiotrófica é uma doença neurodegenerativa progressiva e fatal, caracterizada pela degeneração dos neurônios motores, as células do sistema nervoso central que controlam os movimentos voluntários dos músculos. A salivação excessiva (sialorreia) está presente em cerca de 50% dos casos de esclerose lateral amiotrófica. Dessa forma, surgem medidas terapêuticas alternativas como drogas anticolinérgicas e cirurgia, e recentemente, o uso da toxina botulínica, aplicada em um ponto central das glândulas salivares, muitas vezes guiado por ultrassonografia, demostrou resultados positivos. Objetivou-se revisar a literatura no intuito de demonstrar um método alternativo aos tratamentos de sialorreia em pacientes com esclerose lateral amiotrófica. Em estudos recentes, a eficácia do tratamento com toxina botulínica foi confirmada e, mesmo requerendo novas aplicações, os efeitos colaterais são ínfimos. Ela surge então como alternativa não só ao tratamento de esclerose lateral amiotrófica, mas também para outros pacientes com doenças que apresentem a sialorreia.

Gran parte de la investigacion acerca de la ensenanza de las ciencias se dedica a estudiar la forma o manera en que los estudiantes visualizan los conceptos cientificos. Para Driver (1983) esas ideas o concepciones se conocen como concepciones alternativas; las cuales pueden ocasionar dificultad para comprender los conceptos de las diferentes areas del conocimiento. El proposito de este estudio fue: (a) indagar como las distintas etapas del ABP permiten explorar las concepciones alternativas que poseen los estudiantes de nivel elemental acerca de los estados de agregacion de la materia y, (b) explorar en que medida el ABP permite identificar e incorporar las concepciones alternativas que poseen los estudiantes de nivel elemental con relacion al concepto de estados de agregacion de la materia para facilitar su aprendizaje. Con el fin de explorar las concepciones alternativas en el tema de los estados agregados de la materia se implanto la estrategia de Aprendizaje Basado en Problemas (ABP) con estudiantes de quinto grado de nivel elemental. Se utilizo la metodologia mixta con varias estrategias de recopilacion de datos, como una pre y pos prueba para elucidar el conocimiento previo y al mismo tiempo las concepciones alternativas sobre el tema bajo estudio y luego verificar el aprendizaje en los estudiantes. Asimismo, el uso de mapas conceptuales para determinar la profundidad del tema estudiado y el entrelazamiento de los conceptos Una tercera estrategia fue el grupo focal para tomar en cuenta la impresion de los estudiantes acerca del proyecto ABP. El aspecto colaborativo y cooperativo fue un factor fundamental, ya que el aprendizaje ocurrio en ese contexto educativo. Para los hallazgos de esta investigacion fue tan importante el conocimiento previo como los procesos que se generaban para que la adquisicion del mismo fuera de forma significativa y funcional (Escribano & Del Valle, 2010). La estrategia de ABP constituyo en este estudio una forma para indagar las concepciones alternativas que poseian los estudiantes y a su vez, determinar como el estudiante manejaba dichas concepciones a situaciones que requeririan aplicar su conocimiento para luego modificar las estructuras conceptuales hacia el conocimiento cientifico.

O método Grade of Membership (GoM) tem sido cada vez mais utilizado por demógrafos brasileiros e tem a vantagem de possuir um parâmetro que mensura a heterogeneidade individual, com base nas correlações não-observáveis entre as categorias de resposta das variáveis de interesse, gerando um medida do grau de pertencimento de cada indivíduo a perfis extremos. Alguns autores, contudo, chamam atenção para questões importantes na calibragem dos modelos finais que utilizam o programa GoM versão 3.4, como o problema de identificabilidade – soluções múltiplas para parâmetros estimados. Neste artigo, é sugerido um procedimento capaz de identificar um modelo final com solução única que descreva os tipos puros mais fidedignos à base de dados, em uma tentativa de otimização. Para ilustrar esse processo, utilizou-se uma base de dados correspondente a um levantamento econômico e sociodemográfico de uma população de pequenos agricultores residentes ao longo da Rodovia Transamazônica, no Estado do Pará. Também identificou-se a existência de instabilidade nos parâmetros estimados pelo programa GoM 3.4, sendo proposto um método de estabilização de seus valores. Com esses procedimentos combinados, os usuários do programa GoM 3.4 poderão descrever sua base de dados de forma mais adequada e responder às críticas sobre questões de identificabilidade e estabilidade dos modelos resultantes. Essas soluções empíricas são relevantes por afetarem cálculos de prevalência e de incidência de eventos de interesse, além de trazerem consequências importantes sobre o ponto e o momento corretos para intervenções de políticas públicas ou de planejamento prospectivo em análises de projeção.

Embora os Parâmetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as orientações complementares a esses Parâmetros (PCN+) apontem a importância de uma abordagem significativa de conceitos relacionados à astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano. Este trabalho tem por objetivo analisar os conhecimentos básicos em astronomia dos alunos de EM da escola estadual Batista Renzi, bem como investigar os meios através dos quais estes conhecimentos foram adquiridos. Para tanto foi elaborado um questionário de múltipla escolha aplicado a 310 alunos distribuídos entre as três séries do EM dos períodos matutino e noturno. Dessa forma, observou-se que apenas 34,5% relacionaram as estações do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influência gravitacional da Lua e do Sol como responsáveis pelo fenômeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distância e 34,2% reconheceram uma estrela cadente como meteoro. Em contrapartida, 67,1% compreendiam a sucessão entre dia e noite, 73,9% identificaram o Sol como estrela e 52,3% relacionaram o Big Bang à origem do Universo. Além disso, foram comparadas as respostas de alunos de diferentes séries e períodos, observando-se, dentre outras coisas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tópicos relacionados à astronomia no EM não tem contribuído para uma maior compreensão dos fenômenos e conceitos.

Os aglomerados de galáxias apresentam um interesse especial para a cosmologia observacional. Eles são as maiores estruturas ligadas pela gravitação no Universo e relaxadas na região central. A comparação entre a massa do gás intra-aglomerado (responsável por ~25% da massa total, inferida a partir de observações em raios-X), a massa contida nas estrelas (i.e., nas galáxias) e a massa total (incluindo a matéria escura não bariônica), nos dá informações importantes sobre os processos de formação e evolução de aglomerados. Por exemplo, a razão entre a massa do gás e a massa total é uma medida da fração de bárions no Universo (razão entre a matéria bariônica e matéria escura) e, utilizando a densidade de bárions predita pela nucleosíntese primordial, podemos deduzir a densidade de matéria escura no Universo (cf. White et al. 1993). O objetivo deste trabalho é obter as razões entre as massas do gás, estelar (contida nas galáxias), e a total (massa dinâmica). As massas do gás e total são obtidas a partir das análises fotométrica e espectroscópica em raios-X enquanto que a massa estelar é obtida pela análise fotométrica das galáxias. Esta análise foi aplicada ao aglomerado Abell 496 observado pelo satélite XMM-Newton. A massa contida nas galáxias foi estimada a partir da função de luminosidade obtida por Durret et al. (2002). Para determinar as massas dinâmica e do gás nos precisamos determinar os perfis radiais de densidade e temperatura. Nós apresentaremos aqui estes resultados e suas implicações na eficiência da formação estelar em Abell 496.

O survey infravermelho consiste de observações utilizando a CAMIV no telescópio de 60 cm do LNA. Nosso principal objetivo é melhor caracterizar a população estelar dos braços espirais e de uma estrutura existente no centro galáctico que acreditamos ser devido à existência de uma barra, cujas extremidades estariam localizadas em longitudes galácticas l~23° e l~14°. As observações realizadas em vários filtros (imagens J, H e K) são particularmente importantes nas direções que tangenciam os braços espirais, desta forma, comparamos uma direção que atravessa um braço a uma direção próxima que não passa pelo braço, sendo que ambas possuem a mesma contribuição de contagens foreground. Nas missões realizadas até o presente, observamos a região na direção tangencial ao braço de Scuttum, com observações de l = 30.04° até l = 31.04°, a cada intervalo de longitude de 0.1°, para latitude galáctica de 0.0°, 0.25°, 0.50°. Para as regiões que acreditamos serem as extremidades da barra, observamos as faixas de longitude compreendidas entre -15° £ l £ -13° e 24° £ l £ 22° a cada intervalo de 0.25°, para latitude galáctica de 0.0° e 0.25°. As observações nos filtros J e H foram feitas com tempo de integração de 60s, na banda K, as observações foram feitas utilizando o filtro C1 com tempo de integração de aproximadamente 210 s (12x15s). Elaboramos diagramas cor-cor e cor-magnitude onde podemos verificar a existência de regiões com diferentes contagens e população estelar à medida que um braço espiral é atravessado.

RESUMEN. Chorros Extragalacticos (CE) y Fuentes Radio Extendidas (FRE) son locales de ricos y complejos procesos de plasma magnetizado. Recien tes observaciones indican que esas fuentes son estructuradas en filamen tos. Nos concentramos aqui en el analisis de dos problemas: 1) el prob[e ma de injecci6n,queespropuesto porlas teorias de aceleraci6n de p ? las en plasmas de CE e FRE, que necesitan partfculas que ya tengan ener gfas moderadamente relativisticas para que los procesos de Fermi sean efectivos; y 2) la reciente evidencia observacional de la ausencia de partfculas termicas en CE. El presente modelo pone en evidencia que ambos problemas estan 1ntimamente relacionados uno con el otro. Jafelice y Opher (1987a) (Astrophys. Space Sci. 137, 303) muestram que es espera da una abundante generaci6n de olas Alf cineticas (OAC) en CE y FRE. En el presente trabajo estudiamos Ia cadena de procesos: a) OAC aceleran electrons termicos al largo del campo magnetico de fondo producien- do electrones supratermicos fugitivos; b) que generan olas Langmuir; y c) las cuales por su vez aceleran una fraccion de los electrones fugi- tivos hasta energias moderadamente relativfsticas. Mostramos que supo - niendo que no haya otra fuente de poblaci6n termica a no ser la , la secuencia de procesos arriba puede encargarse delconsumo de los elec- trones termicos en una escala de tiempo %< que el tiempo de vida de la fuente. ABSTRACT: Extragalactic Jets (EJ) and Extended Radio Sources (ERS) are sites of rich and complex magnetized plasma processes.Recent observa - tions indicate that these sources are filamentary structured. We concentrate here on the analysis of two problems:i) the injection problem, faced by theories of particle acceleration in EJ and ERS plasmas, which need particles with already moderately relativistic energies for the Fer mi processes `to be effective; and 2) the recent observational evidence of the abscence of thermal particles within EJ. The present model makes evident that both problems are intimately related to one another. Jafe- lice and Opher (1987a)(Astrophys. Space Sci. 137, 303)showed that an abundant generation of kinetic Alfven waves (KAw) within EJ and ERS is expected. In the present work we study the chain of processes: a) KAW accelerate thermal electrons along the background magnetic field producing suprathermal runaway electrons; b) which generate Langmuir waves and c) which in turn further accelerate a fraction of the runaway electrons to moderately relativistic energies. We show that assuming that there is no other source of a thermal population but the original one, the above sequence of processes can account for the consumption of thermal electrons in a time scale the source lifetime.

Composition of the humin fraction of Terra Preta de Índios soils by NMR and multivariate curve resolution

Most of the soils in the Amazon Region are acid, with low cation-exchange capacity (CEC) values, low fertility, and low production potential. There exists a class soils in this environment that have an archeo-anthropedogenic horizon of pre-Columbian origin, called "Terra Preta de Índios" (TPI), also known as Amazonian Dark Earths. These soils are characterized by higher fertility and more stable organic matter (OM) than the surrounding soils. The high fertility of TPI, and especially their sustainability, is attributed to the high levels of OM and to their physical-chemical properties. Up to 35-45% of the organic C in TPI is in the form of pyrogenic carbon (black carbon), compared to 14% in surrounding soils lacking an archeo-anthropedogenic horizon. Pyrogenic carbon derived from the partial carbonization of ligno-cellulosic materials, is composed of hydrogen-deficient condensed aromatic structures and, as the result of chemical and biochemical transformations, has a high charge density from carboxylic groups linked mainly to the aromatic core. Humin is the most recalcitrant and least understood fraction of soil OM. By definition, humin is the fraction that is not soluble in traditional aqueous alkaline soil extractants. It represents more than 50% of the soil organic carbon (OC) in mineral soils and more than 70% of the OC of lithified sediments, and is therefore the most important pool of the soil OM. However, for a study of humin by NMR it is necessary to isolate it and to achieve a degree of fractionation/purification. In this regard, an appropriate procedure1 has been applied to two soil samples from TPI and the material obtained was studied by solid state 13C NMR. The data analyses were carried out by Multivariate Curve Resolution (MCR). Results and Discussion MCR resolved the spectral matrix into three components, and these can be attributed to wood, humin, and oxidised charcoal materials The spectrum for the wood component agrees very well with that of eucalyptus wood. On the other hand, the humin spectrum shows an intense signal in the alkyl region (0-40 ppm) with a prominent signal for crystalline polymethylene at 33 ppm. These signals, in association with the carboxyl signal (173 ppm), indicate fatty acid origins for these components. Additionally, some altered aromatic structures (a broad and featureless signal centred at 130 ppm) and cellulosic material (110 and 70 ppm) were also evident. The broad signal at 54 ppm was probably from N-alkyl compounds from proteinaceous material since the corresponding O-aryl signal from the alternative methoxyl contribution was lacking. Finally, the oxidised char component was characterised by the broad and featureless signal at 128 ppm and the carboxyl at 172 ppm. The shoulder at 167 ppm gave evidence for carboxyl directly attached to the aromatic backbone. This char component also had minor contributions from aliphatic compounds, such as alkyl, N-alkyl, methoxyl, and carbohydrates. With regard to the estimated concentrations of each of these components, the coarse char samples and the residual humin (before and after DMSO/H2SO4 extraction) presented a higher content of unaltered wood (cellulose and lignin) material. The humin extracted by DMSO/H2SO4 was very rich in long chain aliphatic compounds (alkyl groups: 0-40 ppm). This lipidic fraction was also extracted by the alkali urea treatment and by soil dispersion using ultrasounic vibration. Greater amounts of oxidised char were also isolated following the ultrasonic treatment. This component remained in the residual humin, and it was also abundant in the coarse char fraction, indicating that the solvent systems adopted were unable to solubilise these materials. The extractable humin probably corresponds to fatty acids associated with the clay fraction and the un-extractable fraction was probably composed of particulate char (partially, and oxidised) and vegetable tissues. In conclusion, the extractable humin in these soils is mainly composed of hydrophobic compounds strongly associated with the mineral fraction. The DMSO/H2SO4 solvent is very efficient for solubilising these lipidic compounds. On the other hand, the disruption of the clay aggregates, by ultrasonication, allows additional oxidised char to be released and solubilised by the DMSO/acid and by the alkaline urea systems.

Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as well as proper targeting biopsies. Prospective study of 339 consecutive patients with the standard videoendoscope image analysis were obtained, recorded and stored in a program database. These images were studied with respect to the presence or absence of H. pylori, diagnosed by rapid urease test and/or by histological analysis. Were studied: a) normal mucosa appearance; b) mucosal nodularity; c) diffuse nonspecific erythema or redness (with or without edema of folds and exudate) of antrum and body; d) mosaic pattern with focal area of hyperemia; e) erythema in streaks or bands (red streak); f) elevated (raised) erosion; g) flat erosions; h) fundic gland polyps. The main exclusion criteria were the use of drugs, HP pre-treatment and other entities that could affect results. Applying the exclusion criteria, were included 170 of the 339 patients, of which 52 (30.58%) were positive for HP and 118 negative. On the positive findings, the most associated with infection were: nodularity in the antrum (26.92%); presence of raised erosion (15.38%) and mosaic mucosa in the body (21.15%). On the negative group the normal appearance of the mucosa was 66.94%; erythema in streaks or bands in 9.32%; flat erosions 11.86%; and fundic gland polyps 11.86%. Endoscopic findings are useful in the predictability of the result and in directing biopsies. The most representative form of HP related gastritis was the nodularity of the antral mucosa. The raised erosion and mucosa in mosaic in the body are suggestive but not specific to the infection. The other forms were not conclusive of the presence of HP. Estudos com tecnologias mais recentes como endoscopia com magnificação e cromoscopia mostraram que vários aspectos endoscópicos estão claramente associados à infecção por Helicobacter pylori. A descrição de padrões diferenciados de enantema no corpo gástrico através da magnificação de imagens reavivou o interesse na identificação desses padrões pela endoscopia convencional. Validar os padrões morfológicos de mucosa gástrica usando videogastroendoscopia convencional relacionados à gastrite por infecção por Helicobacter pylori, permitindo previsibilidade do seu diagnóstico e o direcionamento de biópsias. Estudo prospectivo de 339 pacientes consecutivos com análise das imagens de videogastroendoscopia obtidas, gravadas e armazenadas em banco de dados. Estas imagens foram estudadas com relação à presença ou não do Helicobacter pylori diagnosticado por teste rápido de urease e/ou por pesquisa direta por estudo anatomopatológico. Foram estudados: a) aspecto normal da mucosa; b) nodularidade da mucosa; c) enantema inespecífico difuso de antro e corpo; d) enantema em mosaico ou salpicado; e) enantema em estrias ou faixas; f) erosões elevadas; g) erosões planas; h) pólipos de glândulas fúndicas. Os principais critérios de exclusão foram o uso de medicamentos, tratamento prévio de HP e outras entidades que pudessem interferir nos resultados. Aplicando os critérios de exclusão, incluíram-se 170 dos 339 pacientes sendo 52 (30,58%) positivos para Helicobacter pylori e 118 negativos. No grupo positivo os achados que mais se associaram com a infecção foram: nodularidade no antro (26,92%); presença de erosões elevadas (15,38%) e mucosa em mosaico no corpo (21,15%). No grupo negativo o aspecto normal da mucosa foi de 66,94%; enantema em estrias ou faixas em 9,32%; erosões planas em 11,86%; e pólipos de glândulas fúndicas 11,86%. Achados endoscópicos são úteis na previsibilidade de localização e direcionamento de biópsias na pesquisa do HP. A mais representativa forma de gastrite por HP foi o achado de nodularidade na mucosa antral. As erosões elevadas e mucosa em mosaico no corpo são sugestivas, mas não específicas da infecção. As demais formas não foram conclusivas da presença do HP.

to build and validate a scale to assess the risk of surgical positioning injuries in adult patients. methodological research, conducted in two phases: construction and face and content validation of the scale and field research, involving 115 patients. the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning contains seven items, each of which presents five subitems. The scale score ranges between seven and 35 points in which, the higher the score, the higher the patient's risk. The Content Validity Index of the scale corresponded to 0.88. The application of Student's t-test for equality of means revealed the concurrent criterion validity between the scores on the Braden scale and the constructed scale. To assess the predictive criterion validity, the association was tested between the presence of pain deriving from surgical positioning and the development of pressure ulcer, using the score on the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning (p<0.001). The interrater reliability was verified using the intraclass correlation coefficient, equal to 0.99 (p<0.001). the scale is a valid and reliable tool, but further research is needed to assess its use in clinical practice. construir e validar escala de avaliação de risco para lesões decorrentes do posicionamento cirúrgico em pacientes adultos. pesquisa metodológica, conduzida em duas etapas: construção e validação de face e de conteúdo da escala e pesquisa de campo, com a participação de 115 pacientes. a Escala de Avaliação de Risco para o Desenvolvimento de Lesões Decorrentes do Posicionamento Cirúrgico contém sete itens, sendo que cada um apresenta cinco subitens.

To analyze the existence of differences in the use of generic medicines in Brazil according to demographic and socioeconomic variables and acquisition sources of the medicines. Population-based cross-sectional study, conducted with data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines). Data collection took place between September, 2013 and February, 2014 in homes of Brazilian cities (urban area). The use of medicines has been investigated in relation to the treatment of chronic diseases and, in the case of acute events, regarding use over the previous 15 days. Generics were identified by visualization of packaging presented by the users of the medicines. The independent variables used were sex, age, education level, economic class, and region of the Country. The statistical significance of differences between the groups was evaluated by Pearson's Chi-squared test, considering a 5% significance level. The prevalence of generic medicines use was 45.5% (95%CI 43.7-47.3). There was no difference considering education level. The prevalence was higher in females (47.0%; 95%CI 44.9-49.0) than in males (43.1%; 95%CI 40.5-45.8), and were higher with increasing age. Generic medicines were more used in the economic class C (47.0%; 95%CI 44.9-49.1) and in the South (50.6%; 95%CI 46.6-54.6) and Southeast (49.9%; 95%CI 46.8-53.0) regions. Generics accounted for 37.3% of the medicines provided by the Brazilian Unified Health System. Currently, there is a choice of purchase or free provision by the Brazilian Unified Health System, characterized by quality assurance and reduced price regarding branded medicines considered as reference. In the private market, a considerable part of the population is choosing generic medicines thanks to the availability of this option for virtually all medicines most used by the population. Analisar se há diferença no uso de medicamentos genéricos no Brasil segundo variáveis demográficas, socioeconômicas e fontes de obtenção dos medicamentos. Estudo transversal de base populacional, conduzido com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), com coleta de dados entre setembro de 2013 e fevereiro de 2014 em residências de municípios brasileiros urbanos. O uso dos medicamentos foi investigado em relação ao tratamento de doenças crônicas e, no caso de eventos agudos, quanto ao uso nos últimos 15 dias. Os genéricos foram identificados por visualização das embalagens apresentadas pelos usuários dos medicamentos. As variáveis independentes utilizadas foram sexo, idade, escolaridade, classe econômica e região do País. A avaliação da significância estatística das diferenças entre os grupos foi analisada pelo teste Qui-quadrado de Pearson, considerando nível de significância de 5%. A prevalência de uso de genéricos foi de 45,5% (IC95% 43,7-47,3). Não houve diferença por escolaridade, as prevalências foram maiores no sexo feminino (47,0%; IC95% 44,9-49,0) em relação ao masculino (43,1%; IC95% 40,5-45,8) e foram crescentes com o aumento da idade. Maiores usos de genéricos foram encontrados na classe econômica C (47,0%; IC95% 44,9-49,1) e nas regiões Sul (50,6%; IC95% 46,6-54,6) e Sudeste (49,9%; IC95% 46,8-53,0). Observou-se ainda que os genéricos representaram 37,3% dos medicamentos disponibilizados pelo Sistema Único de Saúde . Pode-se concluir que hoje existe uma alternativa de compra ou fornecimento gratuito pelo Sistema Único de Saúde, caracterizada por garantia de qualidade e preço reduzido em relação aos medicamentos de marca comercial considerados como referência. No mercado privado, boa parte da população está optando pelo uso de medicamentos genéricos, graças à disponibilidade dessa opção para praticamente todos os medicamentos mais utilizados pela população.

BACKGROUND. Metabolic syndrome (MetS) is an obesity-driven condition of pandemic proportions that increases the risk of type 2 diabetes and cardiovascular disease. Pathophysiological mechanisms are poorly understood, though inflammation has been implicated in MetS pathogenesis. The aim of this study was to assess the effects of galantamine, a centrally acting acetylcholinesterase inhibitor with antiinflammatory properties, on markers of inflammation implicated in insulin resistance and cardiovascular risk, and other metabolic and cardiovascular indices in subjects with MetS. METHODS. In this randomized, double-blind, placebo-controlled trial, subjects with MetS (30 per group) received oral galantamine 8 mg daily for 4 weeks, followed by 16 mg daily for 8 weeks or placebo. The primary outcome was inflammation assessed through plasma levels of cytokines and adipokines associated with MetS. Secondary endpoints included body weight, fat tissue depots, plasma glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), cholesterol (total, HDL, LDL), triglycerides, BP, heart rate, and heart rate variability (HRV). RESULTS. Galantamine resulted in lower plasma levels of proinflammatory molecules TNF (–2.57 pg/ml [95% CI –4.96 to –0.19]; P = 0.035) and leptin (–12.02 ng/ml [95% CI –17.71 to –6.33]; P < 0.0001), and higher levels of the antiinflammatory molecules adiponectin (2.71 μg/ml [95% CI 1.93 to 3.49]; P < 0.0001) and IL-10 (1.32 pg/ml, [95% CI 0.29 to 2.38]; P = 0.002) as compared with placebo. Galantamine also significantly lowered plasma insulin and HOMA-IR values, and altered HRV. CONCLUSION. Low-dose galantamine alleviates inflammation and insulin resistance in MetS subjects. These findings support further study of galantamine in MetS therapy. TRIAL REGISTRATION. ClinicalTrials.gov, number NCT02283242. FUNDING.

A new compact and low cost Langmuir Probe and associated onboard data handling system are being developed at Instituto Nacional de Pesquisas Espaciais for launching on board one of the future 2U CubeSat missions. The system is a simplified and compacted version of the Langmuir Probe payloads launched on board several Brazilian SONDA III rockets and also developed for the Brazilian scientific satellites SACI-1 and SACI-2. The onboard data handling system will have the dual functions of preprocessing the data collected by the Langmuir Probe and acting as the interface between the experiment and the on board computer. The Langmuir Probe sensor in the form of two rectangular stainless steel strips of total surface area of approximately 80cm2 will be deployed soon after the injection of the CubeSat into orbit. A sweep voltage varying linearly from 0V to 3.0V in about 1.5 seconds and then remaining fixed at 3.0V for 1 second will be applied to the LP sensor to obtain both the electron density and electron temperature. A high sensitivity preamplifier will be used to convert the sensor current expected to be in the range of a few nano amperes to a few micro amperes into a varying potential. In order to cover the large dynamic range of the expected sensor current the preamplifier output will be further amplified by a logarithmic amplifier before being sampled and sent to the data handling system. The data handling system is projected to handle 8 analog channels and 4 digital words of 8 bits each. The incoming data will be stored in a RAM and later sent to the on board computer using a serial RS422 communication protocol. The interface unit will process the telecommands received from the on board computer. The interface is also projected to do FFT analysis of the LP sensor data and send the averaged FFT spectral amplitudes in place of the original unprocessed data. The system details are presented here.

ABSTRACT OBJECTIVE To discuss factors related to the financing of the Basic Component of Pharmaceutical Services within the municipal management of the Brazilian Unified Health System. METHODS The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil – Serviços (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services) is a cross-sectional, exploratory, and evaluative study that performed an information survey in a representative sample, stratified by Brazilian regions It considered different study populations in the sampling plan, which represent primary health care services in the cities. Data were collected in 2015 by two methods: in person, by applying direct observation scripts and interviews with users, physicians, and professionals responsible for the dispensing of medicines in primary care services; by telephone interviews with municipal health managers and municipal professionals responsible for Pharmaceutical Services. The results were extracted from the questionnaires applied by telephone. RESULTS Of the sample of 600 eligible cities, we collected 369 interviews (61.5%) with secretaries and 507 (84.5%) with pharmaceutical services managers. 70.8% of the cities have a computerized management system; and 11.9% have qualification/training of professionals. More than half (51.3%) of the cities received funds for the structuring of pharmaceutical services, and almost 60% of these cities performed this type of spending. In 35.4% of cases, municipal secretaries of health said that they use resources of medicines from the Componente Básico da Assistência Farmacêutica (CBAF – Basic Component of Pharmaceutical Services) to cover demands of other medicines, but only 9.7% believed that these funds were sufficient to cover the demands. The existence of a permanent bidding committee exclusively for acquiring medicines was reported in 40.0% of the cities. CONCLUSIONS We found serious deficiencies in the public financing of medicines, as well as little concern about the formality in the use of public resources, expenses that meet individual demands to the detriment of the community, insufficient resources allocated to the Basic Component of Pharmaceutical Services, and exhaustion of the financing model.

ABSTRACT OBJECTIVE To evaluate the access to medicines in primary health care of the Brazilian Unified Health System (SUS), from the patients’ perspective. METHODS This is a cross-sectional study that used data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Services, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), conducted by interviews with 8,591 patients in cities of the five regions of Brazil. Evaluation of access to medicines used concepts proposed by Penshansky and Thomas (1981), according to the dimensions: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators. RESULTS For the “availability” dimension, 59.8% of patients reported having full access to medicines, without significant difference between regions. For “accessibility,” 60% of patients declared that the basic health unit (UBS) was not far from their house, 83% said it was very easy/easy to get to the UBS, and most patients reported that they go walking (64.5%). For “accommodation,” UBS was evaluated as very good/good for the items “comfort” (74.2%) and “cleanliness” (90.9%), and 70.8% of patients reported that they do not wait to receive their medicines, although the average waiting time was 32.9 minutes. For “acceptability,” 93.1% of patients reported to be served with respect and courtesy by the staff of the dispensing units and 90.5% declared that the units’ service was very good/good. For “affordability,” 13% of patients reported not being able to buy something important to cover expenses with health problems, and 41.8% of participants pointed out the expense with medicines. CONCLUSIONS Results show 70%–90% compliance, which is compatible with developed countries. However, access to medicines remains a challenge, because it is still heavily compromised by the low availability of essential medicines in public health units, showing that it does not occur universally, equally, and decisively to the population.

ABSTRACT OBJECTIVE To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS). METHODS This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student’s t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System. RESULTS Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were “other analgesics and antipyretics” (3rd ATC level) and Losartan (5th ATC level). CONCLUSIONS Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics observed and the difficulties in the use of medicines, older adults are in a situation of greater vulnerability. PMID:29160464

This study describes two major adaptations for the preparation of resin casts in human cirrhotic liver, harvested at the time of transplantation. The first is the way of fixing the catheter in the ostia of the hepatic and portal veins through a cerclage, so as to prevent displacement of the catheter and / or leakage of the resin during its injection. The second is the extension of corrosion time in the NaOH solution, averaging 6.8 days, with daily replacement the solution until complete removal of parenchymal tissue. We applied the method in 14 cirrhotic livers, with good filling and coloring of the portal and hepatic vein territories, using different colors. This allows an anatomical study of these vessels, able to complement the knowledge of the histopathology in research work, and the planning of therapeutic procedures, such as the Trans-Jugular Intrahepatic Port-Systemic Shunt (TIPS). RESUMO Este estudo descreve duas importantes adaptações para o preparo de moldes de resina em fígado humano cirrótico, captado no momento do transplante: a primeira, é a maneira de fixação dos cateteres nos "óstios" das veias hepáticas e porta, através de uma "cerclagem" dos mesmos, de modo a evitar o deslocamento do cateter e/ou extravasamento da resina durante sua injeção, e a segunda, é o prolongamento do tempo de corrosão na solução de NaOH, atingindo a média de 6,8 dias, com a substituição diária da solução, até a remoção completa do tecido parenquimatoso. O método foi empregado em 14 fígados cirróticos com bom preenchimento e coloração dos territórios das veias porta e hepáticas, utilizando cores distintas. Isto permite um estudo anatômico desses vasos, capaz de complementar os conhecimentos da histopatologia em trabalhos de pesquisa, e planejar procedimentos terapêuticos como a derivação porto-sistêmica intra-hepática transjugular (TIPS - Transjugular Intrahepatic Postosystemic Shunt).

ABSTRACT OBJECTIVE To analyze the existence of differences in the use of generic medicines in Brazil according to demographic and socioeconomic variables and acquisition sources of the medicines. METHODS Population-based cross-sectional study, conducted with data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines). Data collection took place between September, 2013 and February, 2014 in homes of Brazilian cities (urban area). The use of medicines has been investigated in relation to the treatment of chronic diseases and, in the case of acute events, regarding use over the previous 15 days. Generics were identified by visualization of packaging presented by the users of the medicines. The independent variables used were sex, age, education level, economic class, and region of the Country. The statistical significance of differences between the groups was evaluated by Pearson’s Chi-squared test, considering a 5% significance level. RESULTS The prevalence of generic medicines use was 45.5% (95%CI 43.7–47.3). There was no difference considering education level. The prevalence was higher in females (47.0%; 95%CI 44.9–49.0) than in males (43.1%; 95%CI 40.5–45.8), and were higher with increasing age. Generic medicines were more used in the economic class C (47.0%; 95%CI 44.9–49.1) and in the South (50.6%; 95%CI 46.6–54.6) and Southeast (49.9%; 95%CI 46.8–53.0) regions. Generics accounted for 37.3% of the medicines provided by the Brazilian Unified Health System. CONCLUSIONS Currently, there is a choice of purchase or free provision by the Brazilian Unified Health System, characterized by quality assurance and reduced price regarding branded medicines considered as reference. In the private market, a considerable part of the population is choosing generic medicines thanks to the availability of this option for virtually all medicines most used by the population.

To characterize the availability of tracer medicines in pharmaceutical services in primary health care of the Brazilian Unified Health System (SUS). This is a cross-sectional and evaluative study, part of the Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). To analyze the availability of medicines, we verified 50 items selected from the Relação Nacional de Medicamentos Essenciais (Rename - National List of Essential Medicines) of 2012. Observation scripts were applied to medicine dispensing services in the primary health care. Interviews were carried out with patients, health care professionals, and public managers, using semi-structured questionnaires. The availability index was presented as the percentage of health units where the medicines were available. For statistical analysis, absolute, relative, and mean frequencies were presented (with 95% confidence intervals). The comparison of groups was carried out by Pearson Chi-square tests or variance analysis, when needed. One thousand, one hundred, and seventy-five observation scripts were filled in a national representative sample composed by 273 cities. Statistically significant differences were observed regarding the type of unit, infrastructure, and presence of a pharmacist between regions of Brazil. The average availability of tracer medicines in primary health care was 52.9%, with differences between regions and sampling strata. This index increased to 62.5% when phytotherapic medicines were excluded. We found limited availability of medicines for treatment of chronic and epidemiological diseases, such as tuberculosis and congenital syphilis. The low availability of essential medicines purchased centrally by the Brazilian Ministry of Health indicates deficiencies in supply chain management. The different views on the availability of tracer medicines in SUS confirm the general availability verified in this study. Among patients, about 60% said they obtain medicines in SUS units, data consistent with the lack of medicines reported by medicine dispensers and in line with physicians' evaluations.

A software to digital image processing to be used in the voxel phantom development.

Anthropomorphic models used in computational dosimetry, also denominated phantoms, are based on digital images recorded from scanning of real people by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI). The voxel phantom construction requests computational processing for transformations of image formats, to compact two-dimensional (2-D) images forming of three-dimensional (3-D) matrices, image sampling and quantization, image enhancement, restoration and segmentation, among others. Hardly the researcher of computational dosimetry will find all these available abilities in single software, and almost always this difficulty presents as a result the decrease of the rhythm of his researches or the use, sometimes inadequate, of alternative tools. The need to integrate the several tasks mentioned above to obtain an image that can be used in an exposure computational model motivated the development of the Digital Image Processing (DIP) software, mainly to solve particular problems in Dissertations and Thesis developed by members of the Grupo de Pesquisa em Dosimetria Numérica (GDN/CNPq). Because of this particular objective, the software uses the Portuguese idiom in their implementations and interfaces. This paper presents the second version of the DIP, whose main changes are the more formal organization on menus and menu items, and menu for digital image segmentation. Currently, the DIP contains the menus Fundamentos, Visualizações, Domínio Espacial, Domínio de Frequências, Segmentações and Estudos. Each menu contains items and sub-items with functionalities that, usually, request an image as input and produce an image or an attribute in the output. The DIP reads edits and writes binary files containing the 3-D matrix corresponding to a stack of axial images from a given geometry that can be a human body or other volume of interest. It also can read any type of computational image and to make conversions. When the task involves only an output image, this is saved as a JPEG file in the Windows default; when it involves an image stack, the output binary file is denominated SGI (Simulações Gráficas Interativas (Interactive Graphic Simulations), an acronym already used in other publications of the GDN/CNPq.
