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.

Space-time description of dengue epidemic in Cruzeiro, SP, in 2006 and 2011

Objective: to identify patterns in the spatial and temporal distribution of cases of dengue fever occurring in the city of Cruzeiro, state of Sao Paulo (SP).Methods: an ecological and exploratory study was undertaken using spatial analysis tools and data from dengue cases obtained on the SinanNet. The analysis was carried out by area, using the IBGE census sector as a unit. The months of March to June 2006 and 2011 were assessed, revealing progress of the disease. TerraView 3.3.1 was used to calculate the Global Moran's I, month to month, and the Kernel estimator.Results: in the year 2006, 691 cases of dengue fever (rate of 864.2 cases/100,000 inhabitants) were georeferenced; and the Moran's I and p-values were significant in the months of April and May (TM = 0.28; p = 0.01; I-M = 0.20; p = 0.01) with higher densities in the central, north, northeast and south regions. In the year 2011, 654 cases of dengue fever (rate of 886.8 cases/100,000 inhabitants) were georeferenced; and the Moran's I and p-values were significant in the months of April and May (I, = 0.28; p = 0.01; I-M = 0.16; p = 0.05) with densities in the same regions as 2006. The Global Moran's I is a global measure of spatial autocorrelation, which indicates the degree of spatial association in the set of information from the product in relation to the average. The I varies between -1 and +1 and can be attributed to a level of significance (p-value). The positive value points to a positive or direct spatial autocorrelation.Conclusion: we were able to identify patterns in the spatial and temporal distribution of dengue cases occurring in the city of Cruzeiro, SP, and locate the census sectors where the outbreak began and how it evolved.

Gestational protein malnutrition impairs c-myc and p63 protein expression, increases prostatic intraepithelial neoplasia incidence and prostatitis aggressiveness in adult male offspring subjected to hormonal handling

Background: Prostate cancer is the second most common cancer diagnosed in men; however its etiology remains unknown. Previous studies have shown that environmental adverse factors, such as maternal nutritional status during pregnancy, can influence fetal development and predispose people to diseases in adult life. The feeding of low-protein diets to pregnant rats result in fetal growth disturbance, androgen/estrogen unbalance and changes in the expression and sensibility of hormone receptors in male offspring. These alterations can promote permanent changes in androgen dependent organs, such as in the prostate. In this sense, we hypothesized that the hormonal unbalance that occurs during aging can lead to an increase in the susceptibility to prostatic disorders. Aim: To evaluate our hypothesis, malnourished male rat offspring were submitted to simultaneous estrogen and testosterone exposure in adulthood, to drive lesions in the rat ventral prostate gland (VP). Methods: 17 week-old Wistar rats (n=48) that received in utero normal protein diet (NP group, AIN93G=17% protein) or low protein diet (RP group, AIN93G modified=6% protein) were given implants with 17β-estradiol plus testosterone administration (NPH and RPH groups) for 17 weeks. The animals were killed at the age of 34 weeks and the VP were excised, weighted and processed for histopathological, immunohistochemical (Ki67, AR, p63, e-caderin, laminin, c-myc and GSTP), biochemical and ultrastructural analysis. Results: Both absolute and relative VP weight from NPH animals were about 30% higher than RPH. Serological data showed that estradiol levels were similar in both groups, but testosterone levels were lower in the RPH male offspring. The steroid hormone exposure in adult life promoted prostate lesions in both RPH and NPH offspring associated with reactive stroma. VP from RPH group exhibited heightened susceptibility to prostatic intraepithelial neoplasia (mainly cribriform and signet ring-cell patterns) and increased the incidence and aggressiveness of prostatitis. In this group, a higher proportion of basal cells, increased proliferation index, lower expression ofthe androgen receptor and increased focus of collagenous micronodules closely associated to epithelial neoplasias were also observed. Conclusion:These observations suggest that maternal protein restriction alters adult prostate response to androgen/estrogen handling and increases susceptibility to prostate diseases.
