The nurse in the management of materials in teaching hospitals
OBJECTIVETo present the nurse's integration within materials management of six teaching hospitals of Paraná - Brazil, and to describe the activities performed by nurses within this process.METHODA study of a qualitative approach and descriptive nature, conducted in teaching hospitals in Paraná, between June and August of 2013. The data collection was conducted through semi-structured interviews with eight nurses who worked in materials management; data were analyzed using content analysis.RESULTSThese showed that nurses perform ten categories of activities, distributed into four of the five steps of the materials management process.CONCLUSIONThe nurse, in performing of these activities, in addition to favoring the development of participative management, contributes to the organization, planning, and the standardization of the hospital supply process, giving greater credibility to the work with professionals who use the materials, and to the suppliers
Impact of freshwater inputs on the spatial structure of benthic macroinvertebrate communities in two landlocked coastal lagoons
Landlocked lagoons are naturally stressed
environments. They are strongly influenced by freshwater
input which not only varies naturally, but which
is also impacted by anthropogenic activities. This
study investigated the direct influence of freshwater
discharges on the distribution patterns and abundance
of benthic communities in two neighbouring landlocked
coastal lagoons, assessing the whole system
and the confluence area of each tributary. Sampling
occurred in the wet and dry seasons of 2011 at two distances from freshwater discharge locations. Both
lagoons were colonized by species from tw
o different pools, freshwater and marine. Freshwater
flow rates had a direct influence on the spatial structure
of the benthic communities of brackish-water/freshwater
interface areas, where also specific taxa can act
as early indicators of freshwater input variations. The
intensity of this influence is highly dependent on
lagoon size, creating spatial heterogeneity or affecting
the entire system. The benthic fauna at the confluence
of the tributary that depends almost exclusively on
groundwater showed the lowest variability, suggesting that the biogeochemical nature of the groundwater
may be a central cause for setting specific ecotones.
The results suggest that benthic communities of
landlocked coastal lagoons can be highly impacted
by flow reduction from freshwater aquifers under
drought conditions or water abstraction activities
Análise das alterações radiográficas pulmonares durante a terapêutica da paracoccidioidomicose
OBJETIVO: Foram analisadas as alterações radiográficas pulmonares em pacientes com paracoccidioidomicose crônica de modo evolutivo, verificando-se as diferenças entre os tratados com um novo agente antifúngico triazólico, o voriconazol, em relação aos que utilizaram a atual droga de escolha para o tratamento, o itraconazol. MATERIAIS E MÉTODOS: Realizou-se estudo comparativo, randomizado, com avaliação das radiografias do tórax obtidas antes, durante e após o tratamento de 39 pacientes, divididos em dois grupos: um recebendo o voriconazol e o outro, itraconazol. A avaliação das radiografias teve como parâmetro uma adaptação do método já estabelecido para a análise de outra doença pulmonar difusa, o esquema ILO (International Labour Office) de classificação das pneumoconioses, classificando-se as lesões em pequenas ou grandes opacidades. RESULTADOS: Os resultados obtidos coincidiram com as descrições prévias existentes em relação à apresentação das alterações radiográficas pulmonares, e a evolução destas ao longo do tratamento foi semelhante nos dois grupos. As pequenas opacidades regrediram parcialmente, ao passo que as grandes opacidades mostraram tendência à regressão completa. CONCLUSÃO: O uso da adaptação do modelo ILO de classificação das pneumoconioses revelou-se útil para o acompanhamento dos pacientes com paracoccidioidomicose crônica ao longo do tratamento, do ponto de vista radiográfico
