Mapas de zonas de risco de epidemias e zoneamento agroclimático para o Cancro Cítrico no Estado de São Paulo

O cancro cítrico, causado pela bactéria Xanthomonas axonopodis pv. citri Valterin et alii 1995, é uma doença conhecida mundialmente e sempre constituiu séria ameaça para a citricultura brasileira. O objetivo do presente trabalho foi analisar as condições climáticas do Estado de São Paulo e desenvolver mapas de zonas de maior risco de epidemias de cancro cítrico. Foram utilizados dados meteorológicos referentes aos anos de 2002 a 2005, os quais foram baseados no modelo de previsão desenvolvido por Campbell & Madden (4) e Hau & Kranz (10). A freqüência dos dados foi horária e quando alguma estação apresentava falha, esses eram extrapolados da estação mais próxima. Foram contabilizados os índices de favorabilidade e posteriormente calculadas as porcentagens de dias favoráveis à ocorrência da doença no período de um ano. A partir destas informações, foram gerados os mapas temáticos do Estado de São Paulo, com a distribuição espacial da porcentagem de dias favoráveis à ocorrência de cancro cítrico. A região Noroeste do Estado foi a que apresentou a maior porcentagem de dias favoráveis à ocorrência de cancro cítrico.

A PERCEPÇÃO DO ESPAÇO PÚBLICO NA MODERNIDADE: UM OLHAR SOBRE A CIDADE DE NATAL

It investigates the perception of the public space in the city of Natal. It approaches, therefore apprehension forms, entails and experiences, in the formalization in the way of seeing, to live and to interact with that part of the urban territoriality. With that perspective, they were focalized, especially, three periods lived in Natal: the first two decades of the century XX, the beginning of the forties, also of the previous century, and the scenery with which that city comes at the present time. With that direction, it puts back in focus, and for reflection, not just an universe that makes possible the people to interact, independent of the individual will of each one, but also the importance of that interaction for the social and political life of the city and for the formation of a wider and interactive vision of the people with yours surroundings

Efeito do ácido alfa-lipóico sobre biomarcadores de estresse oxidativo, inflamação e fatores de risco cardiovascular em hipertensos

Alpha-lipoic acid (ALA) is a potent antioxidant with favourable anti-inflammatory, metabolic and endothelial effects, and has been widely investigated due to its potential against cardiovascular risk factors. This study aimed to evaluate the effect of oral ALA supplementation on oxidative stress biomarkers, inflammation and cardiovascular risk factors in patients with hypertension. This is a double-blind placebo-controlled randomized clinical trial, where the intervention was evaluated prospectively comparing results in both groups. The sample consisted of 64 hypertensive patients who were randomly distributed into ALA group (n = 32), receiving 600 mg / day ALA for twelve weeks and control group (n = 32), receiving placebo for the same period. The following parameters were evaluated before and after intervention: lipid peroxidation, content of reduced glutathione (GSH), enzymatic activities of glutathione peroxidase (GPx) and superoxide dismustase, ultrasensitive C-reactive protein (hs-CRP), triglycerides, total cholesterol and fractions, fasting glucose and anthropometric indicators. There was a statistically significant reduction (p <0.05) in serum concentrations of total cholesterol, very low density lipoprotein (VLDL), high density lipoprotein (HDL), triglycerides and blood glucose. There was a reduction in body weight and waist, abdominal and hip circumferences in the group that received ALA. In addition, there was a statistically significant increase (p <0.05) in the contents of reduced glutathione (GSH) and glutathione peroxidase (GPx) in the group receiving ALA. Oral administration of ALA appears to be a valuable adjuvant therapy, which may contribute to decrease the damage caused by oxidative stress and other risk factors associated with the atherosclerotic process

Prevalência e fatores de risco de leptospirose bovina no Estado do Maranhão

Foram investigados a prevalência e os fatores de risco da leptospirose bovina no Estado do Maranhão. O Estado foi dividido em quatro circuitos amostrais com base em parâmetros de produção distintos que variam conforme os diferentes sistemas de produção, as práticas de manejo, a finalidade de exploração, o tamanho médio dos rebanhos e os sistemas de comercialização. Objetivou-se estudar as características epidemiológicas da leptospirose bovina no Estado do Maranhão, de modo a determinar a prevalência em bovinos e em rebanhos, detectar as sorovariedades de Leptospira spp. presentes, identificar os fatores de risco eventualmente associados à leptospirose em bovinos e diferenciar os circuitos pecuários entre si no que se refere à prevalência de leptospirose. A pesquisa foi realizada em 136 propriedades rurais pertencentes ao circuito I, no qual 841 fêmeas bovinas com idade igual ou superior a 24 meses foram analisadas; 238 do circuito II, com 2.582 fêmeas analisadas; 122 do circuito III, com 869 fêmeas analisadas; e 77 do circuito IV, com 540 fêmeas analisadas; no total, 573 propriedades e 4.832 fêmeas foram estudadas. A presença de anticorpos contra Leptospira spp. foi verificada pela técnica de soroaglutinação microscópica (SAM). Das 4.832 fêmeas bovinas analisadas, 1.904 (35,94%; IC 95% = 33,01% - 38,98%) foram reagentes. Das 573 propriedades analisadas, 380 (64,81%; IC 95% = 61,10% - 68,35%) foram consideradas positivas. As sorovariedades Hardjo e Wolffi foram as mais frequentes em todo o Estado. O circuito III foi o que apresentou menor prevalência de leptospirose em todas as comparações. As variáveis identificadas como fatores de risco de leptospirose foram: presença de equinos (p = 0,000), presença de capivaras (p = 0,034) e rebanhos bovinos com 32 ou mais fêmeas adultas (p = 0,002).

Modelo de avaliação de risco : São o crescimento e a estequiometria dos girinos afetados pelo efeito interativo entre a presença do predador e da densidade de coespecíficos?

Many prey organisms change their phenotype to reduce the predation risk. However, such changes are associated with trade-offs, and can have negative effects on prey growth or reproduction. Understand how preys assess the predation risk is essential to evaluate the adaptive value of predator-induced phenotypic and its ecological consequences. In this study, we performed a mesocosm experiment to test: i) if growth and stoichiometry of Lithobates catesbeianus tadpoles is altered in response to giant water bug presence (Belostoma spp.); ii) if these responses depend on tadpoles density in environment. Here, we show that tadpoles growth and stoichiometry are not changed by predator presence, neither in low nor in high densities. Our results suggest that tadpoles exposed to predation risk regulate their physiology to preserve the elemental stoichiometric homeostase of their body and excretion. Further, point out to need for future studies that elucidate under what conditions growth and stoichiometry are changed in response to predation risk

A Inclusão da pessoa com deficiência visual na UFRN: a percepção dos acadêmicos

A partir des deux dernières décénnies, des changements importants ont touché l éducation des personnes aux besoins éducatifs spéciaux. On est dans une quête permanente de leur inclusion dans les différents niveaux de l enseignement régulier. De ce fait, les institutions éducationnelles se confrontent avec le défi du changement, devant s adapter de plus en plus aux besoins de ces élèves et devenir plus récptives à l égard de tous. Malgré la lenteur de ce changement, cela favorise beaucoup l accès des élèves à des niveaux d enseignement que jamais on aurait supposés, tels que l enseignement supérieur. C est bien dans ce contexte qu au cours de l année 2002 des étudiants handicapés visuels ont accédé aux formations de Philosophie, Economie et Sciences Sociales de l Université Fédérale do Rio Grande do Norte. Cela nous a motivé à conduire une analyse, au cours de 2003, pour connaître de plus près ce processus d inclusion universitaires de trois étudiants handicapés visuels. Comme méthode nous avons utilisé l étude de cas, et l entretien comme instrument de collecte des données. Après l analyse, les résultats montrent bien que l inclusion a permis à ces étudiants de surmonter un tas de barrières, telles que l examen d accès à l Université (Vestibular), outre la chance de se socialiser et d être bénéficiaires d expériences qui, suscités dans un milieu universitaire, vont au-delà de l univers académique. Les collègues de ces étudiants, auprès desquels ils convivent, eux-aussi ont été les bénéficiaires, du fait qu ils ont eu l opportunité d apprendre ensemble les uns avec les autres, tout en respectant leur limitations et potentialités, mais en les appuyant et en les stimulant de mieux en mieux. Il faut reconnaître que plusieurs actions au sein de l Université envisageant l accès et la permanence de ces étudiants ont été couronnées de succès, mais force est de dire qu il y a aussi beaucoup de choses à faire en ce qui concerne : la préparation du corps enseignant et des fonctionnaires ; l orientation de la communauté plus élargie ; la chute des barrières pédagogiques et attitudinales, et surtout l appui humain et matériel indispensables au plein développement de ces étudiants

Água de consumo humano como fator de risco à saúde em propriedades rurais

OBJETIVO: Verificar a qualidade higiênico-sanitária da água de consumo humano em propriedades rurais por meio da contagem de indicadores microbiológicos de potabilidade. MÉTODOS: Foram colhidas 180 amostras de água utilizada para consumo humano das fontes, reservatórios e ponto de consumo em 30 propriedades rurais, situadas na região Nordeste do Estado de São Paulo. Determinou-se o número mais provável de coliformes totais, Escherichia coli e o número de microrganismos mesófilos. Foi verificada a presença de medidas de proteção das fontes de abastecimento. RESULTADOS: Os resultados evidenciaram que 90% das amostras de água das fontes, 90% dos reservatórios e 96,7% de água de consumo humano, colhidas no período de chuvas, e 83,3%, 96,7% e 90%, daquelas colhidas respectivamente nos mesmos locais, durante a estiagem, estavam fora dos padrões microbiológicos de potabilidade para água de consumo humano. CONCLUSÕES: A água utilizada nas propriedades rurais foi considerada um importante fator de risco à saúde dos seres humanos que a utilizam. A adoção de medidas preventivas, visando à preservação das fontes de água, e o tratamento das águas já comprometidas são as ferramentas necessárias para diminuir consideravelmente o risco de ocorrência de enfermidades de veiculação hídrica.

Rotavírus bovino: fatores de risco, prevalência e caracterização antigênica de amostras em rebanhos leiteiros no estado de São Paulo

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Risco à saúde representado pelo consumo de leite cru comercializado clandestinamente

Foram submetidas às contagens de microrganismos mesófilos, Staphylococccus coagulase positiva, e às determinações do número mais provável (NMP) de coliformes totais e de coliformes fecais, 60 amostras de leite cru comercializado clandestinamente nos Municípios de Botucatu e de São Manuel, Estado de São Paulo, Brasil. Os resultados obtidos evidenciaram a ocorrência de 41 (68,3%) e 50 (83,3%) amostras com contagens de microrganismos mesófilos e de coliformes totais, respectivamente, acima dos limites máximos estabelecidos pelo Ministério da Saúde para o leite pasteurizado tipo C. Evidenciaram, ainda, a presença de 30 (50,0%) e 11 (18,3%) amostras contaminadas por cepas de Staphylococcus coagulase positiva e por coliformes fecais, respectivamente. Apenas 5 (8,3%) amostras mostraram-se dentro dos referidos padrões legais.

Efeitos de um programa de intervenção precoce baseado no modelo mais que palavras - HANEN, para crianças menores de três anos com risco de autismo

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response

Body art, existência e conhecimento :a percepção do corpo na Educação Física

In the Renaissance, the anatomy project a map of the body. Since then, the human body has been investigated for innumerable techniques, configuring new landscapes on the condition human being and the proper knowledge. In accordance with Merleau-Ponty (1975), All technique is body technique. It configures and extends the Metaphysical structure of our meat. In this direction, any intervention in the human body, a tattooing, a surgery or a performance, extends the perception and the directions of the existence of the subject. Merleau-Ponty (1975) still affirms, that all technique presents objective interventions. However, the body, ahead of these interventions, doesn t have to be considered only object, but subject that, from the interventions, attributes sensible and meanings through the movements, also being this its way of being in the world. Searching to extend this reflection on the discontinuities between the object body and the subject body, as well as, with the objective to reflect on the relation between the corporal techniques and the production of the subjectivity and the knowledge of the physical education, we reflect on the body art, as one technique of body that marks the exterior of the body, exteriorizing the subjectivity, to search new means to the body and that ahead of this, we believe being able to project innumerable directions for the corporal transformations in the contemporarily. As a method for our reflection in we will support them in the phenomenology. IT presents as a new ontology, in which distinction does not occur enters the operating paper of the citizen that knows and the influence of the known object. The phenomenological understanding of body will be able to contribute with the knowledge of the Physical Education, a time that gives us important arguments on the experience of the body in relation with the nature, the culture, history. To be a body is to be tied to a world that we do not possess completive, but that we do not cease to search it

Herdabilidade de preditores do risco cardiovascular

genetic and environmental factors contribute to the development of cardiovascular risk and that influence can be differentiated by factors characteristic of each population, age and sex. Aim: To investigate the heritability of anthropometric and biochemical markers as predictors of cardiovascular risk in men and women of different age groups, using the method of twins. Methods: A sample of 88 subjects and of these 52 children and adolescents (08-17 years old) 32 monozygotic (20 female and 12 male) and 20 dizygotic (12 female and 08 male) and 36 adults (18-28 years age) 24 monozygotic (08 female and 16 male) and 12 dizygotic (06 female and 06 male), living in the metropolitan region of Natal / RN, Brazil. Anthropometric measures were taken as the height, body mass, waist circumference (WC), sum of skinfolds (ΣDC), fat percentage CUN-BAE, BMI and conicity. Biochemical markers analyzed were: fasting glucose (GLU), total cholesterol (COL), HDL-C, LDL-C and triglycerides (TG). After processing the data the index of heritability (h2) = (S ² MZ) / S ² DZ (DZ S ²) X100 was applied disaggregated by sex and age. Results: The variables showed differential heritability of behavior for men and women, depending on age. The variables with the highest heritability values were ΣDC, GLU, HDL, TG, in men and BMI, WC, ΣDC, GLU, HDL-C and TG in women. And more influenced by the environment variables were: body mass, BMI, Chol, LDL-C in men; body mass and LDL-C in women. Conclusion: Differences index of heritability by gender for cardiovascular risk predictors may assist in planning specific intervention strategies according to gender and stage of life of that individual. It is from the level of environmental influence that can run interventions for changes of components related to cardiovascular risk

Interação entre a equipe de enfermagem e a gestante com diagnóstico de pré-eclâmpsia

The objective of this exploratory descriptive study with a qualitative approach was to analyze the perception of the nursing team and the pregnant women hospitalized with pre-eclampsia regarding the interactive process occurring in the care relationship. Data were collected by semi-structured interview with twenty nursing professionals that work in the high-risk ward and ten pregnant women with the diagnosis of pre-eclampsia. The discourses were analyzed using the content analysis method, in the modality of thematic identification. Three categories were identified that describe the perception of the interaction by the nursing professionals: recognizing the needs of the hospitalized pregnant woman, understanding the woman with pre-eclampsia, and presenting difficulties in the interactive process. With regards to the pregnant women, four categories emerged: recognizing the clinical care, feeling the lack of information, experiencing feelings during the hospitalization, and envisioning the interaction process. The meaning of the discourses was analyzed according to the principles of symbolic interactionism. The results indicate that both, the nursing professionals and the pregnant women, have a limited perception of their interaction, suggesting a need for further reflection about this reality in the health service units and in the nursing education environment

A formação acadêmica do enfermeiro para o SUS na percepção de docentes e discentes da faculdade de enfermagem/UERN

The model of attention to health in Single Health System (Sistema Único de Saúde SUS) presupposes a human-resources policy which prepares professionals of health to guide the services and sanitary practices. The nurse, a member of health staff, takes over an important role in implementation of principles and standards of SUS, being its professional formation necessary to labor organization in this purpose. In this way this study objectifies to analyse the process of formation of the male nurse in the Politic-Pedagogical Project (Projeto Político-Pedagógico PPP) in the perception of learning and teaching of the Faculty of nursing FAEN of the University of The Rio Grande do Norte State UERN. It treats about a descriptive-exploratory study with qualitative and quantitative approach carried out with learning and teaching of the graduation nursing course. In the field research carried out between the months of november, 2006 and february, 2007, were used like instruments the documental research below PPP´s, structured interview directed to the learning and the closed questionnaire applied to the students of eighth and ninth semesters of graduation course. The results of data about the questionnaires elaborated according to National Curricular Patters (Diretrizes Curriculares Nacionais DCN) and the Instrument of Evaluation Course of Graduation MEC were organized according to six lists about the profile of the learning and teaching that participate of the research; of the didactical-pedagogical organization and PPP´s objectives to the just-graduates person to the didactical-pedagogical curriculum organization. For considering the interviews it was adopted thematic analysis of content discribed in lexical analysis by informatical program ALCESTE which provided the organization of the material in five categories: daily problems of SUS consolidation versus nurse formation, dichotomies about FAEN´s nursing course of curriculum versus principles of integralization of graduating process, the just-graduated one from FAEN and its professional insertion united to SUS politic-pedagogical project and the concern about the overcoming of dichotomies of graduation process abilities and necessary competences to the SUS performing nurse. The analysis of informations deriving from documental performance and field research resulted on the verification that, in spite of good intentions, the implementation strategies showed themselves fragile to cope with the rendering of expressed ideal on PPP. There is still a great gap between what´s thought as innovating graduating process and what´s being really implemented

Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.
