High incidence of preventable deaths during childhood in Porto Velho, Rondonia - Brazil

Background: We aimed to estimate and analyze epidemiological profile of deaths during childhood. Method: We used the databases of deaths provided by Information System of mortality between 2006 and 2010. We selected only those records where the occurrence of deaths corresponded to Porto Velho city and those who were aged between 12 and 48 months old at the moment of death. We examined only deaths from preventable causes and poorly defined. Results: The total number of deaths was estimated to be 103, 48.6% male. High frequencies of deaths occurred (39.8%) in children before reaching two years old. Vast majority of deaths (66.9%) was due to preventable causes, 18.4% by poorly defined causes and nearly one in three by external causes. Approximately one in four were due to traffic accidents, 41.9% by drowning and submersion. Also, there were significant frequencies of deaths associated with respiratory diseases (17.5%) and infectious and parasitic diseases (16.6%). Conclusion: These findings reinforce the importance of studies of infant mortality, drawing attention to the debate on policy design to reduce childhood deaths, especially in acting on preventable causes.

Incidence of subclinical endometritis and its effects on reproductive performance of crossbred dairy cows

In dairy cattle, uterine infections are not life threatening and often unavoidable; however, they reduce fertility and increase the production costs of properties. The aim of this study was to evaluate the incidence of subclinical endometritis from 32 to 70 days in milk (DIM) and its effects on the reproductive performance of crossbred dairy cows. Lactating cows (Holstein/Gir; n = 172), with no history of retained placenta, without clinical signs of uterine infection were used. The body condition score (BCS) was evaluated on a scale from 1 to 5. Ultrasound examination was performed to evaluate uterine lining and ovarian activity, while vaginal mucus was analyzed by gloved hand. The diagnosis of subclinical endometritis was performed by endometrial cytobrush technique. The samples were collected, stained, and examined microscopically; positive cases for subclinical endometritis were considered with the presence of a parts per thousand yen5 % of neutrophils. Later, the cows were submitted to conventional artificial insemination or timed artificial insemination. The incidence of subclinical endometritis in the herd was 26 %, and this was not affected by the season of calving, presence of corpus luteum, DIM, and parity. Cows with a BCS a parts per thousand currency sign2.50 had a higher incidence of subclinical endometritis. The conception rate to first insemination and pregnancy rate at 150 days postpartum were not influenced by the presence of subclinical endometritis in crossbred dairy cows.

A distribuição do dengue no estado de São Paulo e suas relações com o clima

This study linked the outbreak of dengue fever occurred in the state of São Paulo in 2007 and the sharp decline in cases reported in the year following the change of El Niño to La Niña. Therefore, raised temperature data for the months of January, February and March 2007 and 2008, recorded in 99 countie, which have allowed maps mean isotherms, maximum and minimum for each of the summers...

Promoção da saúde nas séries iniciais do ensino fundamental: atividades educativas lúdicas e práticas no combate a dengue

A promoção da saúde através da educação pode ser um valioso meio para se informar e atingir mudança de comportamentos nos indivíduos, principalmente em casos de doenças como a dengue, onde é necessária a participação da população para seu controle. O presente trabalho teve por objetivo formular elaborar, desenvolver e avaliar atividades para alunos do ensino fundamental, com caráter mobilizador e abordagem diferenciada do tema dengue, proporcionando ferramentas intelectuais e conhecimento necessários para a aquisição de hábitos saudáveis. Antes da realização destas proposições foram apurados os conhecimentos prévios dos alunos e suas dificuldades, através de um questionário. As atividades sugeridas eram do tipo lúdico e práticas, onde há um maior contato do aluno com o tema, o que proporciona o desenvolvimento de capacidades cognitivas e intuitivas, assim como de socialização, criatividade e questionamento. Estas atividades eram compostas por um experimento de acompanhamento das fases do vetor, jogo, jornal e filmes, onde se procurou sempre atentar as dúvidas e dificuldades dos alunos. Com esse projeto as crianças adquiriram novos conhecimentos e habilidades que podem contribuir para uma conduta que promova a saúde não apenas deles, mas das pessoas que estão a sua volta

Modelos matemáticos e computacionais em dengue

This work was developed starting the study of traditionals mathematical models that describe the epidemiology of infectious díseases by direct or indirect transmission. We did the classical approach of equilibrium solutions search, its analysis of stability analytically and by numerical solutions. After, we applied these techniques in a compartimental model of Dengue transmission that consider the mosquito population (susceptible vector Vs and 'infected vector VI), human population (suseeptíble humans S, infected humans I and recovered humans R) and just one sorotype floating in this population. We found the equilibrium solutions and from their analises, it was possible find the reprodution rate of dísease and which define if the disease will be endemic or not in the population.- ext, we used the method described a..~, [1] to study the infíuence of seasonalíty at vírus transmission, when it just acts on one of rates related with the vector. Lastly, we made de modeling considering the periodicity of alI rates, thereby building, a modeI with temporal dependence that permits to study periodicity of transmission through of the approach of parametrical ressonance and genetic algorithm

A dengue como ferramenta de interdisciplinaridade e popularização científica entre estudantes de ensino fundamental

The majority of the population knows their role in dengue control, preventing the accumulation of water in containers as potential breeding sites of Aedes aegypti, the main vector of dengue. Also known chemical control, widely used by the institutions responsible for the control of endemic diseases. On the other hand, unaware that an alternative measure such biological control through a microbial biopesticide, safe, harmless to health and the environment, can be adopted. Thus, this work reported for elementary school students, simply and clearly, the biological control of mosquitoes through bacterial biopesticide produced locally. Moreover, promoted the interdisciplinary teaching of science and mathematics through the data tabulation and charting on interviews conducted by students, about the level of knowledge of the population about dengue and other related variables.

A gestão de doenças infecto-contagiosas: o impacto do dengue na saúde pública

Os vírus do dengue possuem quatro sorotipos distintos (DENV 1-4) e a infecção por um sorotipo confere imunidade específica em longo prazo apenas para aquele sorotipo. O declínio e a reemergência de epidemias de dengue estão intimamente relacionadas com a migração populacional, o intercâmbio e a introdução de sorotipos, o aumento da população, a urbanização descontrolada, o aumento da infestação por mosquitos do gênero Aedes, que são vetores dos vírus e por mudanças na conjuntura política dos municípios. A doença configura-se como um grande problema de saúde pública e cerca de três bilhões de pessoas encontram-se em risco de contrair o vírus e, anualmente, milhões de casos de dengue são notificados, com aproximadamente 500 mil internações. O impacto econômico da doença não está direcionado apenas aos gastos diretamente relacionados ao tratamento, mas também, ao controle e à prevenção. Além disto, outros desdobramentos podem ocorrer, como gastos gerados por afastamento do trabalho no período de convalescença e por morte devido à infecção pelo vírus. As constantes trocas de equipes de prevenção e controle podem impactar negativamente a doença, favorecendo a dispersão do vetor e a manutenção do dengue no ambiente. Desta forma, o objetivo do trabalho é sistematizar as informações sobre o impacto do dengue na gestão dos recursos destinados a doenças infecto-contagiosas.
