JUSTIFICATIVA E OBJETIVOS: Eventos considerados menores têm assumido papel fundamental na determinação da qualidade do serviço prestado na área da Anestesiologia. O objetivo do presente estudo foi avaliar as principais preocupações dos pacientes em relação ao período pós-anestésico e testar a hipótese de que os efeitos mais indesejados podem ser influenciados por características demográficas. MÉTODO: Um questionário foi respondido por 440 pacientes imediatamente antes da avaliação pré-anestésica. Foram listados os possíveis efeitos indesejáveis no período pós-operatório imediato, baseados em levantamento a partir de dados disponíveis na literatura e considerando o critério de frequência, mas não o de gravidade. Foram avaliados os dados demográficos e pesquisadas as nove preocupações mais frequentemente citadas. As informações coletadas a partir da análise dos questionários preenchidos pelos entrevistados foram relacionadas com seus dados antropométricos, socioeconômicos e educacionais, com o objetivo de avaliar a influência dessas variáveis no perfil das respostas. RESULTADOS: Entre os efeitos indesejados, o temor de acordar intubado foi o mais frequentemente citado como o mais importante, seguido de dor forte no local da cirurgia e acordar durante a cirurgia. A análise dos três efeitos mais indesejados em relação aos dados demográficos não evidenciou diferença estatística significativa, com exceção do item dor no local da cirurgia (menos citada entre pacientes do sexo masculino). CONCLUSÕES: As principais preocupações dos pacientes em relação ao período pós-anestésico são: acordar com um tubo na garganta, dor forte no local da cirurgia e a lembrança de estar acordado durante a cirurgia. A idade, o grau de escolaridade e a renda familiar não determinaram diferenças nas preocupações dos pacientes.

JUSTIFICATIVA E OBJETIVOS: A constante de equilíbrio entre o plasma e o sítio efetor (ke0) é utilizada pelos modelos farmacocinéticos para prever a concentração do fármaco em seu local de ação (Ce). Seria interessante que a Ce de propofol fosse semelhante na perda e na recuperação da consciência. O objetivo deste estudo foi avaliar o desempenho clínico de duas diferentes ke0 (rápida = 1,21 min-1 e lenta = 0,26 min-1) com relação à Ce durante a perda e a recuperação da consciência, usando o modelo farmacocinético de Marsh. MÉTODO: Participaram deste estudo 20 voluntários adultos sadios do sexo masculino. em todos os voluntários, administrou-se propofol em regime de infusão alvo-controlada, modelo farmacocinético de Marsh ke0 rápida e, em outra oportunidade, usou-se o mesmo modelo farmacocinético com a ke0 lenta. Inicialmente, o propofol foi infundido em concentração-alvo plasmática de 3,0µg.mL-1. A perda de consciência e a recuperação de consciência basearam-se na resposta ao estímulo verbal. A Ce foi anotada no momento da perda e da recuperação da consciência. RESULTADOS: Na perda e na recuperação da consciência a Ce pela ke0 rápida foi diferente (3,64 ± 0,78 e 1,47 ± 0,29µg.mL-1, respectivamente, p < 0,0001), enquanto com a ke0 lenta a Ce foi semelhante (2,20 ± 0,70 e 2,13 ± 0,43µg.mL-1, respectivamente, p = 0,5425). CONCLUSÕES: do ponto de vista clínico, a ke0 lenta (0,26 min-1) incorporada ao modelo farmacocinético de Marsh apresentou melhor desempenho que a ke0 rápida (1,21 min-1), uma vez que a concentração de propofol prevista em seu local de ação na perda e recuperação da consciência foi semelhante.

O estresse hídrico afeta profundamente o metabolismo celular vegetal. Neste trabalho, objetivou-se quantificar os efeitos da deficiência hídrica e sua recuperação sobre a atividade das enzimas do metabolismo do nitrogênio: redutase do nitrato (RN), glutamina sintetase (GS) e glutamato sintase (GOGAT) e sobre o acúmulo de prolina em plantas dos genótipos de milho BR 2121 e BR 205. O experimento foi conduzido em casa de vegetação, sob o delineamento inteiramente casualizado, com quatro repetições, utilizando-se vasos que continham 14,3kg de solo. Os tratamentos consistiram da combinação dos dois genótipos e quatro intervalos entre irrigações (1, 3, 5 e 7 dias). No dia da avaliação (49 dias após emergência), os tratamentos com intervalos entre 3 e 7 dias, haviam sido irrigados no dia anterior, caracterizando-se portanto como recuperação da deficiência hídrica leve e severa, respectivamente. As extrações e análises foram realizadas utilizando-se a terceira folha basípeta completamente expandida. As atividades das enzimas estudadas não diferiram entre os tratamentos de estresse hídrico, controle e recuperação do estresse moderado, entretanto as plantas sob recuperação do estresse severo apresentaram atividade enzimática superior à das plantas controle. O acúmulo de prolina livre nas folhas aumentou com o estresse hídrico e respondeu à recuperação do estresse apresentando redução. de modo geral, a atividade enzimática e o acúmulo de prolina apresentaram respostas inversas dentro dos tratamentos.

A criação intensiva de frango gera uma grande quantidade de resíduos ricos em nutrientes cujo uso agrícola pode ser viabilizado pelos produtores, na adubação das culturas comerciais. Objetivou-se avaliar a influência da fertilização com cama de frango na recuperação física de um Latossolo. O experimento foi instalado em um Latossolo Vermelho Distrófico típico, textura média, sob pastagem degradada de Brachiaria decumbens Stapf. Os tratamentos estudados foram: 0, 1.200, 2.400, 4.800 kg ha-1 de cama-frango e 2.400 kg ha-1 de cama-frango + adubação mineral com 36 kg ha-1 N, 60 kg ha-1 K2O e 60 kg ha-1 de P2O5. As aplicações foram realizadas em janeiro de 2004 e o solo amostrado em duas épocas distintas (60 e 210 dias após aplicação), nas profundidades de 0-20 e 20-40 cm, para a caracterização dos atributos físicos: argila dispersa em água, grau de floculação, densidade do solo e porosidade total. O teor de argila dispersa em água decresceu com o aumento das doses de cama aplicadas e, conseqüentemente, houve um incremento no grau de floculação; houve uma pequena redução na densidade do solo e na porosidade total. Os atributos físicos do solo avaliados responderam com maior intensidade às aplicações de cama de frango nas doses variando de 2.666 a 3.750 kg ha-1.

The bulk density and resistance to penetration as indicators of recovery were studied with the objective to investigate the physical quality of a Red Latosol (Oxisol) under restoration for 17 years using green manures, soil correction, gypsum and pasture. The experimental design was a completely randomized with nine treatments and four replications. The treatments were: control (tilled soil without crop); Stizolobium aterrium; Cajanus cajan until 1994 and then substituted by Canavalia ensiformis; lime+S. aterrimum; lime+C. cajan until 1994 and then substituted by C. ensiformis; lime+gypsum+S. aterrimum; lime+ gypsum+C. cajan until 1994 and then substituted by C. ensiformis, the treatments were installed in 1992 and remained for seven years, in 1999 Brachiaria decumbens was planted; two other controls (native vegetation and exposed soil) were also used to compare. Bulk density, resistance to penetration and soil moisture were evaluated. The results were analyzed performing analysis of variance and Tukey test at probability of 5% to compare means. The treatments of reclamation are improving the physical qualities of soil and the results of treatment with C. cajan/C. ensiformis, lime and gypsum attained physical conditioning similar to soil under natural conditions.

The nutritional assessment by 24 hour-dietary recall, anthropometry and blood-components measurements was undertaken in 23 adult patients, 17 males and 6 females suffering of chronic diarrhea from pancreatitis (30%), inflammatory bowel disease (22%), short intestine syndrome (9%) and unknown diarrhea (35%). The nutritional assessment was done at the entry and repeated at the discharge of the hospitalization that averaged 35 days, during which the patients received specific medical treatment along with obstipating diets. The hospitalization resulted in overall improvement of the patients either clinically by reducing their defecation rate or nutritionally by increasing their protein-energy intake and the values of anthropometry and blood components (albumin, free-tryptophan and lymphocytes). When the patients where divided into two groups based on their fecal-fat output one could note the better nutritional response of the group showing steatorrhea than the non-steatorrhea group, with the serum albumin and the arm-muscle circumference being discriminatory between groups. However even in the better recovered patients the indicative values of a satisfactory nutritional status were not accomplished. Thus, these data suggest that besides the overall nutritional improvement seen in the studied chronic diarrhea patients the full-nutrition recovering would demand either or both a longer hospitalization and/or an early-aggressive nutritional support.

A plantation of Eucalyptus urophylla, established in 1984 on a Quartzpsamment Soil, at Altinopolis, São Paulo State, presented in 1989 an medium increment of the cylindrical volume of the trees of 13.97 m 3/ha/year and also showed deficiency symptoms of potassium, calcium and magnesium. At 4.33 years after planting were applied two doses of nitrogen (0 and 10 g/tree of N), potassium (0 and 20 g/tree of K 2O) and of dolomitic lime (0 and 500 g/tree), combined in a randomized block design arranged in a factorial way (2 × 2 × 2), with four replications, in order to study the recuperation of the tree growth rate. Evaluations of the trees growth were performed at 4.33, 5.67, 6.75 and at 7.58 years when cutting the plantation was done. The soil fertility and leaf concentrations of N, K, Ca and Mg were analyzed before and after the application of the treatments. The accumulation and distribution of biomass and of these nutrients in the tree components and in the litter, and the economic studies referring to the volumes of wood were also evaluated 7.58 years after planting. Potassium fertilization increased the mass of potassium in stemwood, stembark, foliage, fruits and litter, but the increase was greater in foliage and in the stembark. Liming increased the mass of magnesium in stemwood, stembark, foliage and litter, but the increase was greater in the litter. There was no isolated effect of nitrogen fertilization. The growth rate of trees was recovered with the potassium application, which increased the mean annual increment (MAI) of cylindrical volume from 13.85 m 3/ha/year without fertilizer to 16.82 m 3/ha/year. At 7.58 years after planting, there was observed an effect of the N x K x dolomitic lime interaction in the wood production. In the absence of nitrogen and dolomitic lime, the application of potassium increased the real volume of 43% and there was a gain of US$ 86.79/ha.

In the Research and Teaching Farm of the State University of São Paulo (UNESP) - Campus of Ilha Solteira, located in Selviria, in Mato Grosso do Sul State, a study was conducted with the objective of investigating the resistance to penetration of a highly degraded soil due to construction of a Hydroelectric Power Plant. The experimental design was a completely randomized, with five treatments and five replications. The treatments were constituted of the following uses and managements: area in advanced state of degradation; area under regeneration cultivated 13 years with Pinus; area under regeneration cultivated 11 years with green manure and pasture; degraded area with natural regeneration; and area with natural vegetation (savanna). The system where the area was under regeneration with Pinus cultivation and the niches with natural regeneration were the closest to natural condition (savanna). Except for the natural area (savanna), all others presented a higher resistance to penetration in the layer of 0.20-0.40 m, which represents serious limitations for growth of plant roots.

GPS active networks are more and more used in geodetic surveying and scientific experiments, as water vapor monitoring in the atmosphere and lithosphere plate movement. Among the methods of GPS positioning, Precise Point Positioning (PPP) has provided very good results. A characteristic of PPP is related to the modeling and / or estimation of the errors involved in this method. The accuracy obtained for the coordinates can reach few millimeters. Seasonal effects can affect such accuracy if they are not consistent treated during the data processing. Coordinates time series analyses have been realized using Fourier or Harmonics spectral analyses, wavelets, least squares estimation among others. An approach is presented in this paper aiming to investigate the seasonal effects included in the stations coordinates time series. Experiments were carried out using data from stations Manaus (NAUS) and Fortaleza (BRFT) which belong to the Brazilian Continuous GPS Network (RBMC). The coordinates of these stations were estimated daily using PPP and were analyzed through wavelets for identification of the periods of the seasonal effects (annual and semi-annual) in each time series. These effects were removed by means of a filtering process applied in the series via the least squares adjustment (LSQ) of a periodic function. The results showed that the combination of these two mathematical tools, wavelets and LSQ, is an interesting and efficient technique for removal of seasonal effects in time series.

A comparative evaluation was made of the use of natural language versus two specialized indexing languages, aiming to demonstrate the influence of the availability of indexing languages on the functioning of information retrieval systems. The study was conducted within the ambit of the construction of search strategies by subject in online university library catalogs. The precision ratio was calculated to determine the accuracy of each indexing language in subjectbased information retrieval. From the comparative evaluation of the use of indexing languages, it was concluded that the term specificity required by the user during retrieval was more satisfactory when the query was made through controlled languages, whose availability and simplicity is also an indispensable requisite.

It is well established in the literature that musculoskeletal injuries are important compromising agents in the performance of Thoroughbred horses. In Brazil, there are no studies on the interrelation between lay-up period post-injury and retirement of racehorses due to musculoskeletal injures. The aim of this study is to determine the relationship between rehabilitation times of track injures and variables of prior race performance and later return to competitions. The radiographic reports and athletic history of 416 thoroughbreds during the period between 2003 and 2006 were examined; they were selected based on continued presentations after injury diagnosis. The temporal variables (post-injury rehabilitation time) and performance variables (race score before and after injury) were evaluated by multivariate correspondence analysis of the data and represented in perceptual maps. Correspondence was observed between most of the animals that had a short lay-up post-injury and variables that denote decline in subsequent performance. Considering the integrity of the bone healing process as crucial for the horse to be able to handle later training routines and competitions, shortening this period could lead to an imbalance of the bone repair metabolism, thus resulting in performance decline and compromise of the horse athletic career.
