Comparação entre os resultados do índice de normalização internacional medidos em dispositivo portátil (Hemochron Jr.) e por metodologia convencional

OBJETIVO: Comparar os resultados do Índice de Normalização Internacional (INR) obtidos pelo teste rápido com os do método convencional nos pacientes em terapia de anticoagulação oral com varfarina sódica. MÉTODOS: Para 383 pacientes tratados com varfarina (idade média: 56,5 anos; 207 mulheres), o INR foi determinado em sangue capilar pelo equipamento Hemochron Jr. e comparado com os resultados de amostras de plasma venoso analisadas pelo teste convencional realizado em equipamento Coag-A-Mate. Foram avaliados os resultados do desempenho global das amostras e dos seguintes subgrupos: INR < 2,0, entre 2,0 a 3,5 e > 3,5. RESULTADOS: A comparação entre os valores de INR dos dois métodos resultou em um coeficiente de correlação (r) de 0,86. Entretanto, a análise das diferenças médias entre os resultados dos dois testes, considerando os três subgrupos, apresentou diferenças estatisticamente significativas (p < 0,001): 0,14 ± 0,21 (INR < 2,0); 0,54 ± 0,31 (2,0 < INR < 3,5) e 1,64 ± 1,10 (INR> 3,5). O cálculo do teste t-pareado de Student resultou em um p < 0,001 para os três subgrupos analisados. CONCLUSÃO: A adoção do teste rápido para monitoramento da anticoagulação oral apresenta restrições. Esse método subestimou a intensidade da anticoagulação nos três subgrupos estudados.

The associated microflora to the larvae of human bot fly Dermatobia hominis L. Jr. (Diptera: Cuterebridae) and its furuncular lesions in cattle

The microflora associated to furuncular lesions, larvae and pupae of Dermatobia hominis, as well as the relationships between parasite, host and microflora associated, as a comprehensive microsystem, has been studied. One hundred and two furuncular myiasis due to D. hominis larvae in several breeds of cattle were studied and the following bacterial species were significant: Staphylococcus aureus, S. epidermidis, S. warneri, Bacillus subtilis and Escherichia coli. Closely related, the microflora associated to 141 samples from first, second, third instar larva and both external surface and larval cavities has been studied. The representative associated microflora to the larvae were: S. aureus, B. subtilis, S. hycus and Moraxella phenylpiruvica, Moerella wisconsiensis, Proteus mirabilis and P. vulgaris, M. phenylpiruvica, M. wisconsiensis, P. mirabilis and P. rettgeri were the representative microflora associated to 64 pupae of D. hominis.

Hemilucilia segmentaria (Fabricius, 1805) (Diptera: Calliphoridae) as new biological vector of eggs of Dermatobia hominis (Linnaeus Jr., 1781) (Diptera: Oestridae) in Reserva Biológica do Tinguá, Rio de Janeiro, Brazil

The aim of this note was to record for the first time the finding of Hemilucilia segmentaria acting as biological vector of Dermatobia hominis, during a study of the diversity of Calliphoridae at Reserva Biológica do Tinguá, Rio de Janeiro, Brazil. The insects were captured using traps baited with chicken vicera, for a period of 28-30 h twice per month. In the period of one year, 1987 insects were collected, 7.5% of which belonged to the H. segmentaria; of these a female was captured in May 2001, carrying a mass of 20 eggs on the left side of its abdomen.

BUDDHISM AND MODERNITY: IN THE MARGIN OF DONALD S. LOPEZ JR.'S "BUDDHISM AND SCIENCE

ABSTRACT The present article aims at setting the issue of the relationship between Buddhism and science in a historical and philosophical frame wider than that one taken into account by the international scholarship so far. The historical point of view allows us to conclude that the narrative that connects Buddhism with science is not based on features intrinsic to Buddhist thought. In fact, such narrative prospered thanks to the development of a dialectic, typical of the 18th and 19th centuries, between science and religion. The philosophical point of view allows us to conclude that such narrative is backed by a metaphysical-like thought that denies the specificity of both science and Buddhism.
