EDGE EFFECT AND DYNAMICS OF WOODY PLANTS IN AREA OF CAATINGA VEGETATION IN CANAUBAIS, RN

Considering the importance of studies in communities dynamics, especially in vegetation sites with anthropogenic disturbs as Caatinga of Northeastern Brazil, was evaluate the edge effect caused by the opening of a oil duct on the dynamics of plants in three physiognomies of Caatinga (open shrub, riparian shrub dense and shrub dense) over 15 months (May/2007, January/2008 and August/2008), taking into account the hypothesis that there are differences in the dynamics in areas near edge and more distant. In each situations were evaluated edge and interior, so much in terms of trees in five plots of 10 x 10 m contiguous as of regeneration of the plants in plots of 2 x 2 m. Were calculate mortality, recruitment and growth rates in the edge and interior. Most important differences in terms of edge and interior occurred in open shrub Caatinga. The largest fluctuations in the values of density and diameter occurred at the edge, which indicates that the opening of the duct caused greater interference in this situation.232415

Atraso na busca por serviço de saúde para o diagnóstico da tuberculose em Ribeirão Preto (SP) Delay in the search for health services for the diagnosis of tuberculosis in Ribeirao Preto, Sao Paulo

Foi analisado o atraso na busca por serviço de saúde para o diagnóstico da Tuberculose (TB) em Ribeirão Preto, 2009, em um estudo epidemiológico, transversal, realizado com 94 doentes. Utilizou-se questionário baseado no Primary Care Assessment Tool, adaptado para avaliar a atenção à TB. Estabeleceu-se a mediana (15 dias ou mais) para caracterizar atraso na busca pelo primeiro atendimento. Através da Razão de Prevalência, identificaram-se as variáveis relacionadas ao maior atraso. O primeiro serviço de saúde procurado foi o de pronto atendimento (57,4%). Verificou-se um maior tempo na procura pelos serviços de saúde entre os doentes: do sexo masculino; com idade entre 50 a 59 anos; com renda familiar inferior a cinco salários mínimos; forma pulmonar; casos novos; não coinfecção TB/HIV; não consumiam bebida alcoólica, conhecimento satisfatório sobre TB (apresentou significância estatística na associação com o atraso) e que não procuravam o serviço de saúde próximo do domicílio antes de ter TB. Verificou-se a necessidade de capacitação para os profissionais de saúde quanto aos sinais e sintomas da doença, reduzindo as barreiras de acesso ao diagnóstico oportuno da TB e divulgação ampla para a comunidade em geral.<br>The scope of this paper is to analyze delays in locating health services for the diagnosis of tuberculosis in Ribeirao Preto in 2009. An epidemiological and cross-sectional study was conducted with 94 TB patients undergoing treatment. A structured questionnaire, based on the Primary Care Assessment Tool adapted for TB care was used. A median (15 days or more) was established to characterize delay in health attendance. Using the Prevalence Ratio, the variables associated with longer delay were identified. The first healthcare services sought were the Emergency Services (ES) (57.5%). The longest period between seeking assistance occurred among males, aged between 50 and 59, who earned less than five minimum wages, had pulmonary TB, were new cases, were not co-infected with TB/HIV, did not consume alcohol, had satisfactory knowledge about TB before diagnosis (with a statistically significant association with delay) and who did not seek healthcare close to home before developing TB. There is a perceived need for training healthcare professionals about the signs and symptoms of the disease, reducing barriers of access to timely diagnosis of TB and widely disseminating it to the community in general
