Influência do fotoperíodo e da temperatura na intensidade de doença causada por Fusarium graminearum em Egeria densa e E. najas

Um isolado de Fusarium graminearum vem sendo estudado na UNESP, Campus de Jaboticabal, como agente de controle biológico de Egeria densa e E. najas, macrófitas aquáticas submersas, muito problemáticas em reservatórios de hidrelétricas. O presente trabalho teve por objetivo estudar os efeitos do fotoperíodo (0; 4; 8 e 12 h diárias de luz) e da temperatura (15 ºC, 20 ºC, 25 ºC, 30 ºC e 35 ºC) no controle destas plantas em condições de laboratório. A cada dois dias foram avaliados os sintomas nas plantas inoculadas com F. graminearum, atribuindo-se notas de severidade de doença, por um período de oito dias após a inoculação. Também foi avaliado o crescimento das plantas por meio do ganho de massa fresca, expresso em porcentagem. A maior severidade de doença foi observada quando ambas as espécies foram mantidas no escuro e a menor em fotoperíodo de 12 h. A temperatura de 30 ºC proporcionou maior severidade de doença em ambas espécies. Egeria densa apresentou maior produção de massa fresca no regime de 12 h de luz e de temperaturas abaixo de 25 ºC e menor produção no regime de escuro total e nas temperaturas de 30 ºC e 35 ºC. Egeria najas apresentou menor produção de massa fresca no regime de escuro total e nas temperaturas de 25 ºC a 35 ºC.

Influência da concentração de inóculo e da idade da planta na intensidade de doença causada por Fusarium graminearum em Egeria densa e E. najas

Um isolado de Fusarium graminearum estudado na UNESP/Campus de Jaboticabal, onde foi comprovada sua eficácia no controle de Egeria densa e E. najas, macrófitas aquáticas submersas. Para estudar o efeito de diferentes concentrações do inóculo na severidade de doença, foram conduzidos experimentos em incubadoras para BOD, com concentrações variando em um décimo, de 0,1 até 1,4 g/l de arroz moído colonizado com F. graminearum. Para verificar os possíveis efeitos da idade da planta sobre a severidade de doença, plantas com, no mínimo 35 cm, de comprimento foram excisadas em segmentos correspondentes às idades de crescimento. Os tratamentos com concentrações de inóculo a partir de 0,5 g/l apresentaram sintomas. Todos os tratamentos inoculados com o fungo, nas concentrações a partir de 0,5 g/l, apresentaram drástica redução na produção de biomassa fresca. Todos os segmentos utilizados como plantas-teste (0 a 32 cm de comprimento) apresentaram suscetibilidade ao fungo. Os ponteiros de plantas de ambas as espécies apresentaram maior severidade de sintomas no sexto e oitavo dias após a inoculação, contudo, os segmentos correspondentes às idades 2 e 3 apresentaram maior redução de biomassa fresca quando inoculadas, apesar de não apresentarem sintomas tão severos quanto a idade 1. Com relação ao ganho de biomassa fresca, as testemunhas apresentaram sempre maior crescimento do que os respectivos tratamentos inoculados, contudo os segmentos correspondentes à idade 4 apresentaram menor ganho de biomassa fresca do que as demais idades.

Doença renal medular cística em uma cadela Yorkshire Terrier: relato de caso

Uma cadela da raça Yorkshire Terrier apresentou hematêmese, distensão abdominal, poliúria e polidipsia. Após o exame clínico do paciente, estabeleceu-se a suspeita clínica de nefropatia. Os resultados dos exames laboratoriais revelaram anemia normocítica normocrômica e concentrações séricas de uréia (306mg/dl) e de creatinina (3,6mg/dl) acima dos valores de referência. Ao ultra-som bidimensional observaram-se áreas císticas hipoecóicas e anecóicas, padrão renal hipercogênico e perda da relação corticomedular. À necropsia, a região medular apresentou grande quantidade de cistos pequenos em meio a tecido conjuntivo fibroso. A lesão tubulointersticial cortical foi a responsável pela insuficiência renal resultante. Firmou-se diagnóstico de nefrite tubulointersticial.

Praxiologia, representação social de menopausa e práticas educativas de enfermeiras na estratégia saúde da família

This research, whose theme is related to climacteric, aims to know the social representation of menopause developed by the nurses working for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa PB, as well as identifying its structure and verifying the way it interferes with the assistance and educational practices to the climacterial user. In the theoretical level, it is based on a model that articulates the social representations theory, the central nucleus complementary theory and the central concepts of Pierre Bourdieu s praxiology: habitus, cultural capital, social field and symbolic power. A hundred and forty-seven female nurses who work for Estratégia Saúde da Família (Family Health Strategy) in João Pessoa (PB) took part in this research, and the data collection period was from February 2008 to March 2009. As to the methods and techniques, we used the method to determine the central nucleus based on the free association of words, a questionnaire to identify certain regularities that constitute the nurses habitus, and the semi-structured interview to explore opinions and attitudes when facing assistance situations and educational practices and to collect other relevant information. The data analysis was developed, when referring to the free associations, with the help of the EVOC software, which is a group of articulated programs which carry out the statistical analysis of the evocations and the identification of the possible elements of both the central nucleus and the peripheral system of the social representation. As to the questionnaire, we used the descriptive statistical analysis and the analysis of correlation between the variables. The interviews were submitted to a categorical analysis of the content. The EVOC result indicated that the cognition hormone was the only element of the central nucleus of the social representation of menopause. Due to its symbolic value and structuring power, this central nucleus ensures the strict and, at the same time, flexible character of the representational content. The analysis of the social advancement, of some fundamental features of the group habitus, as well as the analysis of its insertion in the health field and of the attitudinal opinions and dispositions concerning the assistance given to the climacterial user, and the analysis of the pedagogical dimension of this assistance, all these analyses lead to the conclusion that the nurses who took part in this research share a social representation of the menopause resulting from the association of different technical and scientific knowledge. These derive from the biomedical pattern as well as from hegemonic values which disqualify old age and overvalue youth, from pedagogical conceptions arising from patterns that are presently regarded as authoritative and old-fashioned and from cultural references (responsible for the semantic variations concerning the central nucleus) which are specific to the subgroups the nurses belong to. This research enables the creation of opportunities for discussion between active nurses working for Estratégia Saúde da Família, and the nurses who are teachers at institutions of higher education, aiming at linking theory to practice, so that they can find ways of thinking about the climacteric and working, in a more comprehensive way, with users who are experiencing this stage of life

Estratégia para erradicação de focos da Doença de Aujeszky em suínos no Estado de São Paulo

Este trabalho teve como objetivo a avaliação de duas estratégias para erradicação de focos da doença de Aujeszky (DA) em suínos criados comercialmente no estado de São Paulo. Foram identificados dois focos da enfermidade, no município de Cerqueira César, um apresentando somente animais sororreagentes (Foco 1) e outro, casos clínicos da doença (Foco 2). Foram avaliadas duas estratégias de erradicação, uma por eliminação dos sororreagentes e outra por despovoamento gradual, com acompanhamento durante 12 meses. A erradicação por eliminação dos sororreagentes foi aplicada no Foco 1 e compreendeu na identificação por exame sorológico, isolamento e abate dos positivos; vacinação dos negativos e reposição no plantel com animais provenientes de propriedade livre. No início dos trabalhos, 68% do plantel era positivo e ao final 51%. No Foco 2 utilizou-se o despovoamento gradual, onde todos os animais foram enviados ao abate sanitário, realizado vazio sanitário nas instalações, seguido pelo repovoamento com animais livres. Esta última estratégia, nas condições desse trabalho, mostrou-se a mais eficaz, pois erradicou a DA.

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

Emprego da microscopia eletrônica na avaliação pós-vacinal de epitélio traqueal de patos (Anas platyrhynchos) imunizados contra a doença de Newcastle

Avaliou-se o emprego da microscopia eletrônica de varredura no estudo da reação respiratória pós-vacinal em epitélio traqueal de patos (Anas platyrhynchos) imunizados contra a doença de Newcastle. Foram utilizadas 48 aves, distribuídas em quatro grupos: T1 - grupo de aves-controle (não vacinadas), T2 - grupo de aves vacinadas com a estirpe Ulster 2C, T3 - grupo de aves vacinadas com a estirpe B1 e T4 - grupo de aves vacinadas com a estirpe LaSota. Independente do grupo experimental, as aves não apresentaram sinais clínicos detectáveis de reação respiratória pós-vacinal. Ao microscópio eletrônico de varredura, observou-se que os animais vacinados com as estirpes B1 e LaSota desenvolveram descamação epitelial da traqueia, enquanto os vacinados com a estirpe Ulster 2C não, mostrando um epitélio traqueal íntegro, semelhante ao do grupo-controle. Os patos vacinados com a estirpe B1 mostraram evidências de regeneração epitelial da traqueia decorridos 21 dias pós-vacinação, o que não ocorreu com os vacinados com a amostra LaSota.

Envelhecer entre pássaros e anjos: um estudo etnográfico sobre o processo saúde doença do idoso no contexto familiar

Study, a descriptive-like one, is guided by ethnographic principles which have analyzed the elderly within the familiar context in his/her process of health and aging, in the neighborhood called Felipe Camarão, located in the western administrative region of Natal, RN, a Northeastern city of Brazil. The participants are elders aging 61 to 84 years old, living in this referring neighborhood, whose majority is constituted of migrants from the rural region of the state of the RN, retired, including widows, widowers and married couples, with low school-educational degree. For the information gathering it was utilized a semi-structured interview, the participant observation and the field diary, being put into effect, in majority, in the houses and in the Family Health Unit, in a period between March and October of 2006. For the results discussion it was utilized an analysis of thematic content and the program ALCESTE (In Portuguese, Análise Léxica por Contexto de um Conjunto de Segmentos de Texto or Lexical Analysis by Context of a Set of Text Segments), which through have emerged two corpus: the corpus I, Family and the elderly, and corpus II, The elderly and the aging within society. The analysis of the results has permitted to conclude that the family, also used by the public policies as a strategy of their practices in health, it is a necessary base support for the elderly citizen in his/her process of aging and of health. The elders familiar contexts have allowed this study to identify the existence of minimal social conditions of life, of new rearrangements of the current families by means of the plurigenerational acquaintanceship and the active presence of the elderly woman as a maintainer of this family; also by means of conflicted relationships among one another but in a bearable level of acquaintanceship. Different conceptions about the aging and the elderly generate disagreement and divergency however the family support and help for the solving of these problems and the attention to health are proceeding from the family components. However, it is noticed that loneliness is something present in these elder s everyday lives. About the attention to health, in a basic level of it, it was noticed that there are still a lot of gaps, mainly concerning promotional and preventing actions, deserving a higher sensitization and effort by the local health institutions

Vivendo e aprendendo no ambiente hospitalar: Percepções de crianças sobre a doença

This study focuses on the child within the hospital environment. Its purpose is to describe children s perceptions of their illness and time in hospital and to identify their main hardships during treatment. This study has a qualitative nature and is theoretically and methodologically supported by the creative and sensitive method developed by Cabral (1998), studies by Piaget, Vygotsky and Wallon on child development, and studies conducted by Pinto (2005), Collet (2004), Chiattone (2003), Silva (2002), Lima et.al (1999) on in-patient children. For this study, 13 children between the ages of 7 and 12 at a public hospital institution specialized in child care in the city of Natal, Rio Grande do Norte, were interviewed. As a criterion for taking part in this study the children would have to have been in hospital for over three days and be fully capable of physically and emotionally interacting with the researcher at the time the interview took place. Analysis drew on the study of the empirical material made up of interviews and a field diary where notes had been entered for the children s reactions, expressions and gestures. Results show that there is some understanding, on the part of these children, of their illness, with their parents as the main informants. They accept being in hospital because they need treatment, but they realize that life becomes different especially on account of the constraints resulting from the illness and the hospital itself. The main hardships during treatment are: lack of recreational activities in the evenings and on the weekends within the hospital environment; absence of family members, especially brothers and sisters; and lack of explanation on the part of health professionals regarding some procedures as these are being carried out. Our conclusion is that children perceive illness and the hospital environment as something that changes the rhythm of their lives bringing on them perturbations, fears and anxieties. Hence, we suggest that professionals working with in-patient children should be especially prepared to deal with these children and their parents, aiming at bringing down fears and anguishes, clear their doubts and, in addition, advise the parents in respect of their children s treatment while in hospital and after hospital discharge. The hospital environment should also be cheerful and colorful and have a toy room under the coordination of persons especially prepared for that purpose

Gritos de silêncio: na voz dos familiares cuidadores de portadores da doença de Alzheimer

This work is an investigation related to issues of those who take home care of people who suffer from Alzheimer disease (AD). Thus, it is justified by the need to acknowledge how these relatives perform this task and in which ways they do this. The study has is analytical and qualitative methodology with the use of a thematic oral history approach. The subjects of the research were nine relatives of those who suffer from AD that participate in the home care group in the Candelária neighborhood in the city of Natal in Rio Grande do Norte-Brazil. The data was collected using a semi-structured questionnaire and interview that was booked in advance and had full support from the care takers. After information collection, three thematic axles were defined. After this procedure, three analisys subcategories were also defined. The first thematic axle emphasizes the so called movement of rite of passage, when the relative becomes a care taker of a person with AD. The second category deals with the care takers strategies, either related to their own behalf or on their relative. It is possible to infer that amongst other forms of help, the care taker needs to rely on a support network, such as health services, groups composed by multiprofessionals that enable better articulation between family and collaborators. The dimension related to faith and spirituality was also observed and pointed out as an important aspect in the emotional support process for these relatives. In the third axle the perspectives of struggle, conquests of the right to health and life quality of those who suffer from AD as well as their relatives was observed. These also deal with dreams and hope

Avaliação do impacto do treinamento de clínica em hanseníase e sua contribuição para o aumento da detecção da doença no Estado do Rio Grande do Norte

Hansen´s disease is considered a serious public health problem. In 2006, the Ministry of Health reported that worldwide, Brazil ranked 2nd in the number of cases of the disease, surpassed only by India. The North region is the geographical area in Brazil that presents the most cases. In the state of Rio Grande do Norte, the disease is considered to be eliminated because its prevalence has been identified as 1 per 10.000 inhabitants, criteria established by the State Elimination Letter of 2005. Training programs have been offered by the Coordination for the Control of Hansen´s Disease Program of Rio Grande do Norte, PCH-RN since 1997, with the support of the English governmental agency Leprosy Relief Association, LRA, with no evaluation having been conducted. The objective of this study was to evaluate the training programs in clinical diagnosis of Hansen´s disease and their contribution to the detection of the disease in the state of Rio Grande do Norte. The study was conducted in seven municipalities that are known as Regional Public Health Units (URSAPs): São José de Mipibu URSAP I, Mossoró URSAP II, João Câmara URSAP III, Caicó URSAP IV, Santa Cruz URSAP V, Pau dos Ferros URSAP VI and Natal, capital city of the State, in the Metropolitan Region. Physicians and nurses of the Family Health Program PSF were interviewed as to their perceptions of the implementation of the training program in clinica diagnosis of Hansen´s Disease conducted by the PCH-RN. They evaluated their own practice and the training program. These professionals presented a positive evaluation of the program and gave suggestions for future courses. The results of this study suggest the need for permanent education. Data of the disease obtained from the official records of the Secretariat of Health and from the interviews indicate that health education is the means to control Hansen´s disease effectively

Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope

Trajetória de vida de ex-portadores de hanseníase com histórico asilar

Hansen's disease, despite significant advances regarding the diagnosis, treatment and control still carries an immense burden of stigma as a result, mainly of its socio-historical marked by prejudice and isolation of patients, translated by suffering, abandonment and psychosocial problems. Thus, the study set out to rescue the life stories of former leprosy patients with a leprosarium history; recovering the life trajectory stories of these former patients and to identify common factors to these life stories. Exploratory-descriptive study with a qualitative approach, using the Life History Research Methodology. The sample was composed by twelve former leprosy patients who lived while undergone treatment in the Colony Hospital St. Francisco de Assis, located in Natal, Rio Grande do Norte. The network was composed without considering sex and age limit, patients that lived in the Colony Hospital for at least six months and who agree to participate freely in the study. The subjects with special physical needs (hearing) or mental disabilities and those who do not agree to participate were excluded. A semi-structured interview was used to data collection, the interviews were recorded in the household context of individual, residents in neighborhoods Felipe Camarão, Km 6 and Jardim America, more precisely at Nova Vida village, all located in that district. The data collected were subjected to the technique of thematic content analysis. This study had obtained an appropriate consent of the UFRN Research Ethics Committee under the protocol No. 016/2010. After extensive and careful readings of life stories we identified three themes that guided the data analysis: behavioral stages, social exclusion and, stigma and prejudice. Thus, it is clear that the practice of compulsory confinement of patients in nursing homes and the mythical image of Hansen's disease as being ugly and deformed, contributed to solidifying the historical stigma surrounding the disease and its patients, raising in society and family attitudes and feelings of exclusion, prejudice and fear. Moreover, there are remarkable stories in the lives of these interviewed reporting suffering, denials, anger that reverberate to this day, affecting negatively the social and family reintegration of these individuals. As a result, we see the need for managers and local health professionals, especially nurses, rethink existing strategies for social rehabilitation of the patient and ex-leprosy patient aiming to suppression unjust and harmful stigma rooted in image and stories of these individuals

Identificação de crianças e adolescentes com suspeita de câncer: uma proposta de intervenção

Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte

Comunicação dos enfermeiros com usuários do gênero masculino: um estudo representacional

Communication is seen as vital function. Through it, individuals and organizations relate to each other, the environment and the shares of their own group, influencing each other to turn facts into information. The user of the male part of a group of patients whose health policy is still in development. This fact can create insecurity in the nurse to establish a process that promotes disease prevention, promotion and / or recovery of health for that user. Aiming to elucidate this, the present study aimed to: apprehend the social representations of nurses communication with the users were male, looking for disease prevention, promotion and recovery of his health; identify the factors that influenced, positively or negatively on the effectiveness of nurses communication with the users were male and investigate the strategies used by nurses to clarify communication with the users were male. In order to achieve the goal raised, this study was a descriptive, exploratory and qualitative approach. Was based on theoretical and methodological framework social representations of Denise Jodelet and Serge Moscovici. The project has, through no Parecer nº 649/10, approval of the Ethics and Research HULW. During data collection, we used a semi-structured script and a diary interviews with 24 nurses in basic health units of district-Mangabeira Health District III, the city of João Pessoa (PB). The results were analyzed using the technique of content analysis according to Bardin (2007). Classifying the research subjects and identified three categories and five nuclei of the central ideas. The categories identified: the grasp of the RS communication of nurses with male users, identifying factors that influence the effectiveness of nurses' communication with users and male research on the strategies used by nurses to the elucidation of the communication with male users. The nuclei of the central ideas found: social representations of nurses' communication with the users of the male is externalized as difficult, different, difficult, not technical (knowledge) specific, with a dubious sense in relation to its therapeutic action, the factors examined as positive in this communication were based on the connection between professional and user look in detail and not mechanistic, in preventive actions, the dynamics of care, accessibility, participatory care, humanization, and qualification service. Whereas served as negative factors for the communication, signed on the behavioral differences of men, the feminization of nurses, lack of training for professionals in relation to the subject, prescriptive conduct and prejudice (concerns) sociocultural. Another related consolidated core strategies employed for the occurrence of such communication. Given these results, it was realized the importance of social representations for the consecration of a single language, the common understanding of reality on the nurse's communication with the user in male and determination of changes in the behavior of nurses and the user to the establishment of more effective strategies for obtaining a therapeutic communication between them
