MICROBIOLOGICAL CONTAMINATION of A HEMODIALYSIS CENTER WATER DISTRIBUTION SYSTEM

The microbiological monitoring of the water used for hemodialysis is extremely important, especially because of the debilitated immune system of patients suffering from chronic renal insufficiency. To investigate the occurrence and species diversity of bacteria in waters, water samples were collected monthly from a hemodialysis center in upstate São Paulo and tap water samples at the terminal sites of the distribution system was sampled repeatedly (22 times) at each of five points in the distribution system; a further 36 samples were taken from cannulae in 19 hemodialysis machines that were ready for the next patient, four samples from the reuse system and 13 from the water storage system. To identify bacteria, samples were filtered through 0.22 mu m-pore membranes; for mycobacteria, 0.45 mu m pores were used. Conventional microbiological and molecular methods were used in the analysis. Bacteria were isolated from the distribution system (128 isolates), kidney machine water (43) and reuse system (3). Among these isolates, 32 were Gram-positive rods, 120 Gram-negative rods, 20 Gram-positive cocci and 11 mycobacteria. We propose the continual monitoring of the water supplies in hemodialysis centers and the adoption of effective prophylactic measures that minimize the exposure of these immunodeficient patients to contaminated sources of water.

Influence of thermal annealing treatment in oxygen atmosphere on grain boundary chemistry and non-ohmic properties of SnO2 center dot MnO polycrystalline semiconductors

The present work studied the influence of thermal treatment in oxygen rich atmosphere on heterogenous junctions in Mn-doped SnO2 polycrystalline system presenting varistor behavior. The samples were prepared by conventional oxide mixture methodology, and were submitted to heat treatment in oxygen rich atmosphere at 900 degrees C for 2h. The samples were characterized by X-ray diffraction, scanning electron microscopy, dc and ac electrical measurements. The results showed that there is an evident relationship between the microstructure heterogeneity and non-ohmic electrical properties. It was found that for this SnO2 center dot MnO-based varistor system the heat treatment in oxygen rich atmosphere does not necessarily increase the varistors properties, which was related to the decrease in the grain boundary resistance. The results are compared with Co-doped SnO2 varistors and ZnO based varistors. (C) 2008 WILEY-VCH Verlay GmbH & Co. KGaA, Weinheim.

Clinical Profile, Predictors of Mortality, and Treatment of Patients after Myocardial Infarction, in an Academic Medical Center Hospital

OBJECTIVE: To evaluate clinical profiles, predictors of 30-day mortality, and the adherence to international recommendations for the treatment of myocardial infarction in an academic medical center hospital. METHODS: We retrospectively studied 172 patients with acute myocardial infarction, admitted in the intensive care unit from January 1992 to December 1997. RESULTS: Most patients were male (68%), white (97%), and over 60 years old (59%). The main risk factor for coronary atherosclerotic disease was systemic blood hypertension (63%). Among all the variables studied, reperfusion therapy, smoking, hypertension, cardiogenic shock, and age were the predictors of 30-day mortality. Most commonly used medications were: acetylsalicylic acid (71%), nitrates (61%), diuretics (51%), angiotensin-converting enzyme inhibitors (46%), thrombolytic therapy (39%), and beta-blockers (35%). CONCLUSION: The absence of reperfusion therapy, smoking status, hypertension, cardiogenic shock, and advanced age are predictors of 30-day mortality in patients with acute myocardial infarction. In addition, some medications that are undoubtedly beneficial have been under-used after acute myocardial infarction.

Medidas contraceptivas e de proteção da transmissão do HIV por mulheres com HIV/Aids

OBJETIVO: Atualmente, entre as mulheres, a relação sexual é a forma de transmissão que mais tem contribuído para a feminização da epidemia de HIV/Aids. Na busca constante de se estabelecer padrões mais adequados de orientação para saúde, investigou-se o uso de medidas contraceptivas, que também sirvam de proteção da transmissão do HIV, entre mulheres portadoras de HIV/Aids. MÉTODOS: Estudo exploratório desenvolvido em um serviço público ambulatorial de um hospital universitário, referência aos portadores de HIV/Aids da região centro-sul do Estado de São Paulo, no período de cinco meses (2000 a 2001). Foram estudadas 73 mulheres portadoras da infecção pelo HIV, ou com Aids. Os dados foram obtidos por meio de um formulário que investigava a caracterização sociodemográfica, as formas de anticoncepção utilizada e a situação sorológica do parceiro sexual. Os dados foram analisados descritivamente e os conteúdos das respostas abertas, agrupados em temas. Foi aplicado o teste exato de Fisher para análise de algumas variáveis, em nível de 5%. Para a análise de conteúdo utilizou-se a proposta de Bardin. RESULTADOS: A maioria das mulheres estava em fase de vida reprodutiva, eram casadas e foram contaminadas quase exclusivamente por meio da relação heterossexual. Entre elas, 35,4% referiam parceiro sexual discordante quanto à sorologia anti-HIV, e 13,7% utilizavam formas inadequadas de anticoncepção que também não protegiam da transmissão do HIV. CONCLUSÕES: Os resultados alertam para a necessidade de ações educativas continuadas quanto a experiências sexuais mais seguras entre portadoras de HIV/Aids, para que elas possam discutir com seus parceiros outras formas de exercerem sua sexualidade, sendo capazes de estabelecer opção contraceptiva mais consciente, de maneira a zelar pela sua saúde, do parceiro e até do concepto.
