Pesquisa Agropecuária Brasileira , 2001,
Abstract: Procurou-se avaliar os efeitos do plantio direto e da consorcia o soja (Glycine max (L.) Merrill) e milho (Zea mays L.) sobre pragas e inimigos naturais. Os tratamentos constituíram um fatorial 3 x 2 (monocultura de soja, monocultura de milho, consorcia o soja-milho x plantio direto, plantio convencional), em blocos casualizados. Os insetos foram amostrados pelo método do pano, rede entomológica, procura visual e armadilha de suc o. Entre os insetos-pragas do milho, Maecolaspis assimilis ocorreu em maior número no sistema de plantio convencional; o mesmo ocorreu com os predadores Cycloneda sanguinea e Doru sp. Por outro lado, M. assimilis e o predador Toxomerus sp. foram mais numerosos na monocultura de milho em rela o à cultura do milho consorciado com soja. Dos insetos-pragas da soja, destacaram-se pelo maior número Anticarsia gemmatalis e Diabrotica gracilenta, no sistema de plantio convencional, e o mesmo aconteceu com a espécie da família Trichogrammatidae, enquanto as espécies da família Eulophidae foram mais numerosas na soja sob sistema de plantio direto. Na soja consorciada com milho foi maior o número de insetos-pragas Megalotomus sp. e Maecolaspis sp. e dos inimigos naturais Geocoris sp., Lebia concina, Orius sp., Braconidae e Scelionidae.

Abstract: the knowledge of the diversity and distribution of ground arthropods contributes for the development of sustainable agricultural systems. this work was carried out at the paulista state university, jaboticabal campus, state of s?o paulo, brazil, during the period from february to april 2004. the objective was to analyse the community of carabidae, staphylinidae, formicidae e araneae through faunistic indexes, to determine the spatial distribution and interespecific interactions of predominant species in soybean (glycine max (l.) merr.), corn (zea mays l.) and rubber tree (hevea brasiliensis muell. arg.). the arthropods were sampled by pitfall traps distributed each 10 m in two transects of 210 m which crossed the rubber trees and advancing 60 m in the crop lines. the fauna was characterized by shannon-wiener diversity index, evenness and morisita similarity index. the differences among the occurrence of predominant species in the habitats were determined by variance analysis, and the interespecific interaction by pearson correlation. the soybean and corn under no-tillage system provided better structured carabids, ants and spiders communities than the rubber trees. among 88 captured species, 20 species were predominant and the spatial distribution of them showed that odontocheila nodicornis (dejean), glenus chrysis gravenhorst, castianeira sp. and eight ant species were more abundant in the rubber tree compared to soybean and corn. the abundance of the carabids calosoma granulatum perty and o. nodicornis decreased with increased density of the formicids pheidole sp.1 and odontomachus chelifer latreille, respectively.

Abstract: introduction: this work proposes to improve the transmission of information between requiring physicians and radiologists. objectives: evaluate the implementation of a structured report (sr) in a university hospital. methods: a model of a structured report for thyroid sonography was developed according to information gathered from radiologists and endocrinologists working in this field. the report was based on a web platform and installed as a part of a radiological information system (ris) and a hospital information system (his). the time for the report generation under the two forms was evaluated over a four-month period, two months for each method. after this period, radiologists and requiring physicians were questioned about the two methods of reporting. results: for free text, 98 sonograms were reported to have thyroids with nodules in an average time of 8.71 (+/-4.11) minutes, and 59 sonograms of thyroids without nodules were reported in an average time of 4.54 (+/- 3.97) minutes. for sr, 73 sonograms in an average time of 6.08 (+/-3.8) minutes for thyroids with nodules and 3.67 (+/-2.51) minutes for thyroids without nodules. most of the radiologists (76.2%) preferred the sr, as originally created or with suggested changes. among endocrinologists, 80% preferred the sr. discussion: from the requiring physicians' perspective, the sr enabled standardization and improved information transmission. this information is valuable because physicians need reports prepared by radiologists. conclusions: the implementation of a sr in a university hospital, under an ris/his system, was viable. radiologists and endocrinologists preferred the sr when compared to free text, and both agreed that the former improved the transmission of information.

Abstract: snapping syndromes occur during certain movements in several joints and may be accompanied by local pain and crepitation or audible snapping sensation. snapping joints may eventually have no pathologic significance and in this case no treatment is required. there is an array of intra- and extra-articular causes of snapping syndrome and the lack of precise clinical findings impairs the definition of the most appropriate imaging method to confirm the diagnosis. the present study is aimed at discussing the most frequent causes of snapping syndrome in different joints, emphasizing the indications and limitations of each of the different diagnostic methods in specific situations of the clinical practice.

Abstract: gadolinium-based contrast agents are much safer than the iodinated ones; however complications may occur and should be recognized for appropriate orientation and management. the total incidence of adverse reactions to contrast agents in magnetic resonance imaging ranges between 2% and 4%. cases of severe acute reactions to gadolinium, such as laryngospasm and anaphylactic shock, are rare. chronic complications secondary to the use of gadolinium also can occur and, recently an association between its use and a rare dermatologic disease occurring in patients with renal failure has been reported. nephrogenic systemic fibrosis was the subject of an official health notification issued by the american food and drug administration. this progressive disease is characterized by hardened skin with fibrotic nodules and plaques which may involve other parts of the body. patients who have been affected by this disorder presented chronic renal failure, with metabolic acidosis and had been submitted to magnetic resonance angiography, probably involving exposure to large amounts of intravenous paramagnetic contrast. this review is aimed at presenting a succinct description of the gadolinium-based contrast agent types, possible secondary complications, their preventive measures and management.

Abstract: the objective of this study was to analyze carabid and staphylinid fauna through several faunistic indexes and to obtain the population fluctuation of the dominant species in forest fragment and soybean-corn crop in no-tillage and conventional cropping system. the samplings of the coleopteran were carried out from november/2004 to april/2007, in guaíra, s?o paulo, being biweekly during the crop period and monthly in the off-season crop. for obtaining the samples it was used pitfall traps, distributed in two transects of 200 m long being 100 m in the culture and 100 m in the fragment. the fauna was characterized by indexes of diversity, equitability, and abundance. in no-tillage system the larger number of carabid and staphylinid species and the equitability and diversity indexes indicated that the community of those beetles shows a better structure when compared with the conventional cropping system. among the carabid species abaris basistriatus stood out for having been characterized as dominant in crop and forest fragment of the two experimental areas. the species scarites sp. 4 and a. basistriatus generally presented population peaks when the crop soybean counted less than 30 days of the implantation, the other species presented population peaks that were observed in varied times of the crops. pluvial precipitation was the meteorological variable that obtained the largest number of positive correlations followed by minimum temperature.
Enfrentar ?novos riscos? e resgatar a cidadania perdida: práticas de Servi?o Social no seio das políticas de redu??o de danos

Abstract: in this article, we analyse social work practices in the domain of harm reduction policies, taking as empirical subject the practice of social workers inserted in harm reduction programs among illicit drug users in the oporto metropolitan area. the results suggest a professional practice guided for a conception of harm reduction as public health measure supported by the principles of tolerance and citizenship, aiming the reduction of individual harm in order to prevent collective risks. we concluded that the social work practices oscillate between the regulation of ?psychoactive risks? and the obligation with the efectivation of the citizenship rights, through a relation with the users of illicit drugs ruled by the defense of the human dignity and protection of the right to have health.
