Ten years of hospital admissions for liver cirrhosis in Portugal

Background and aims More data on epidemiology of liver diseases in Europe are needed. We aimed to characterize hospital admissions for liver cirrhosis in Portugal during the past decade. Patients and methods We analyzed all hospital admissions for cirrhosis in Portugal Mainland between 2003 and 2012 registered in the national Diagnosis-Related Group database. Cirrhosis was classified according to etiology considering alcohol, hepatitis B, and hepatitis C. Results Between 2003 and 2012, there were 63 910 admissions for cirrhosis in Portugal Mainland; 74.4% involved male patients. Etiologies of admitted cirrhosis were as follows: 76.0% alcoholic, 1.1% hepatitis B, 1.4% hepatitis B plus alcohol, 3.6% hepatitis C, and 4.0% hepatitis C plus alcohol. There was a significant decline (P <0.001) in admissions for alcoholic cirrhosis, whereas hospitalizations for cirrhosis caused by hepatitis C or hepatitis C plus alcohol increased by almost 50% (P <0.001). Patients admitted with alcoholic plus hepatitis B or C cirrhosis were significantly younger than those with either alcoholic or viral cirrhosis (53.1 vs. 59.4 years, respectively, P <0.001). Hospitalization rates for cirrhosis were 124.4/100 000 in men and 32.6/100 000 in women. Hepatocellular carcinoma and fluid retention were more common in viral cirrhosis, whereas encephalopathy and variceal bleeding were more frequent in alcoholic cirrhosis. Hepatorenal syndrome was the strongest predictor of mortality among cirrhosis complications (odds ratio 12.97; 95% confidence interval 11.95–14.09). In-hospital mortality was 15.2%. Conclusion Despite the decline in admissions for alcoholic cirrhosis and the increase in those related to hepatitis C, the observed burden of hospitalized liver cirrhosis in Portugal was essentially attributable to alcoholic liver disease.

A informação estatística na tomada de decisão das Bibliotecas do Ensino Superior em Portugal

Este estudo procurou, por um lado, caracterizar as bibliotecas das Universidades públicas portuguesas em termos de recolha de dados estatísticos, seu tratamento e posterior utilização na gestão e tomada de decisão nessas bibliotecas. Por outro lado, procurou auscultar a satisfação do staff e a satisfação dos utilizadores dessas mesmas bibliotecas. Além desta competente mais descritiva, este estudo incluiu também uma componente explicativa baseada num modelo teórico que sugere, primeiramente, a existência de uma relação entre a utilização de informação estatística (IE) na gestão e tomada de decisão e a satisfação do staff e a satisfação dos utilizadores. E, seguidamente, a presença de uma relação de interdependência entre o grau de satisfação do staff e o grau de satisfação dos utilizadores, tal como é sugerido pela teoria da cadeia de lucro na prestação de serviços (Heskett et al., 1994). Foi possível apurar a existência de uma cultura de recolha de dados estatísticos, tratamento e utilização dessa informação para a gestão e tomada de decisão entre as bibliotecas participantes. O estudo também revela que a recolha e utilização de IE tem um impacto positivo na satisfação dos utilizadores, mas afecta negativamente a satisfação do staff com o ambiente de trabalho. / ABSTRACT; This study characterizes the Portuguesa Higher Education Libraries with respect to the collection of data, its statistical analysis and subsequent use in the management and decision making of these Libraries. ln addition, the study also tried to obtain information on the level of satisfaction of staff and users in the same Libraries. Besides this descriptive component, this study includes an explicative component based on a theoretical model. This model first suggests the existence of a positive relationship between the use of statistical information in management and decision making in a Library and the level of satisfaction of users and staff. A second prediction of the model is the existence of an interdependence relationship between the level of satisfaction of the staff and the level of satisfaction of the users, as it is suggesting by the service-profit-chain theory (Heskett et al., 1994). The results reveal the existence of a culture of data collection, statistical analysis of the data and subsequent use in management and decision making among the participant libraries. The study also shows that the collection and use of statistical information has a positive impact on the level of satisfaction of the users but a negative impact on the level of satisfaction of staff regarding the job environment.

Cerâmicas da necrópole da idade do bronze de Alfarrobeira (Silves) : análises macro e microscópicas

Neste trabalho estudam-se três fragmentos de recipientes cerâmicos, recolhidos no interior de duas cistas da necrópole, do Bronze do Sudoeste, de Alfarrobeira (Silves). Os trabalhos efectuados sobre tais fragmentos constaram: da observação macroscópica, na superfície de fractura; da observação em lâmina delgada, ao microscópio petrográfico. São, até ao presente, escassos os trabalhos realizados, no nosso país, sobre análises de pastas cerâmicas recorrendo ao microscópio petrográfico. Parece-nos, no entanto, que se trata de método particularmente aplicável ao estudo das cerâmicas pré-históricas. Estas, com efeito, ao contrário das cerâmicas mais recentes, em geral de pastas mais finas e depuradas, encerram grande quantidade de elementos não plásticos, frequentemente de mineralogia variada. Estão, pois, reunidas as condições para que, através do estudo petrográfico, se possam constituir agrupamentos de pastas, de acordo com a respectiva mineralogia para, numa fase ulterior, tendo presente as características petrográficas dos afloramentos geológicos da região mais ou menos adjacente, se possam definir prováveis zonas de abastecimento da respectiva matéria-prima ou outras informações a que o estudo comparado dos diferentes tipos de pastas devam conduzir. Foi tendo em consideração tais preocupações que se decidiu pela realização do presente trabalho.

Faunas plistocénicas do Concelho de Cascais

Boa parte do Concelho de Cascais é ocupada por afloramentos calcários, do Jurássico e do Cretácico (ZBYSZEWSKI, 1964). Explicam-se, deste modo, as numerosas cavidades cársicas, embora de diferente tamanho e características, até ao presente reconhecidas (CARDOSO, 1982). Entre elas, avultam, pelos restos faunísticos recolhidos, o algar de Cascais e a gruta de Porto Covo, esta de interesse acrescido por ter, também, fornecido importantes artefactos neolíticos e calcolíticos (PAÇO & V AULTIER, 1942). Este trabalho versará o estudo paleontológico dos materiais recuperados em ambas as jazidas, a partir do qual procuraremos esboçar as características paleoecológicas vigentes na região, no final do Plistocénico.

Between the Atlantic and the Mediterranean : the late bronze age around the Tagus estuary (Portugal) : economic, social and cultural aspects

This paper deals with the importance, quantity and diversity of Late Bronze Age sites known around the Tagus estuary. The material culture points out to the existence of cultural stimuli from very different origins: from the Iberian Peninsula inner, the North Atlantic and the Mediterranean basin, related to the social organization and the economy of the populations that inhabited this region between the XIII century BC and the IX century BC, according to the available radiocarbon data. These populations interacted with the first Phoenicians that arrived to the region at the end of this period, after episodic relations of trading with their antecedents, from Central Mediterranean region.

Faunal remains from an Almohad (Ad XII/XIII) silo at the Castle of Aljezur (Portugal)

The analysis of a faunal collection from a storage silo found in the castle of Aljezur, dating from the Almohad period (XII/XIIIth centuries AD), is presented. It appears that the community occupying the castle concentrated on hunting species such as the rabbit, wild boar, red deer and Iberian lynx, while evidences of stockbreeding were scarce and centered upon caprines with horses and chicken playing minor role. The presence of a large dog has been assumed to be an aid for hunting but possibly also in herd keeping. With the exception of the lynx, all large mammals evidenced traces of consumption. The domestic cat is taken to represent a pet whereas the lynx had probably a role as a fur provider. It should be noted that equids and the pond turtle were probably food items. Rodents are taken to represent commensals whereas the toad of the Genus Bufo probably represented an intrusive element.

The transition to agriculture in south-wertern Europe : new isotopic insights from Portugal's Atlantic coast

For the past 15 years, a succession of stable isotope studies have documented the abrupt dietary transition from the Mesolithic to the Neolithic in Western and Northern Europe. Portugal, with its Late Mesolithic shell middens and burials apparently coexisting with the earliest Neolithic, further illustrates the nature of that transition. Individuals from Neolithic contexts there had significantly different diets to their Mesolithic counterparts. No evidence was found for a transitional phase between the marine oriented Mesolithic subsistence regimes and the domesticated, terrestrial Neolithic diet. Two later Neolithic individuals, however, showed evidence for partial reliance on marine or aquatic foods. This raises questions about the possible persistence of marine dietary regimes beyond the Mesolithic period. This article is followed by a brief note by Mary Jackes and David Lubell.

Longitudinal distribution and lateral pattern of megalopal settlement and juvenile recruitment of Carcinus maenas (L.) (Brachyura, Portunidae) in the Mira River Estuary, Portugal

Settlement is a critical process in the life history of crabs, and thus affecting the abundance, distribution and structure of estuarine communities. The spatial pattern of settlement of megalopae of the shore crab Carcinus maenas along a longitudinal estuarine gradient (Mira River Estuary, Portugal) was examined, as well as its effects on the juvenile population. To measure megalopal settlement, four replicate collectors were deployed in six equally spaced stations along the estuarine axis. Juveniles were collected on the same locations with a quadrat randomly deployed on the substrate. To assess fine-scale megalopal settlement within a curved region of the estuary, replicate collectors were deployed on both margins along Moinho da Asneira curve. Megalopae settled differently along the six longitudinal points, with a tendency to attenuate their settlement upstream. Within the curved region, megalopae preferentially settled on the left margin collectors, probably due to the weaker velocity speeds felt on this margin. Concerning the overall juvenile density, there were significant differences among the stations distributed along the estuary, but they did no reflect a longitudinal dispersion attenuation pattern. Size-frequency distribution of the juvenile population showed that the average size is higher on the left margin. Recruits (carapace length between 1.0 mm and 3.4 mm) were more abundant on the upstream stations. Density of early juveniles (3.4 mm-6.5 mm) and juveniles (6.5 mm-10 mm) was more stable throughout the estuary axis than that of recruits. This distribution pattern may result from tidal excursion processes or mechanisms to avoid biotic interactions, such as predation and competition. (c) 2006 Elsevier Ltd. All rights reserved.

Aplicação do princípio da igualdade na legislação experimental em Portugal

The experimental legislation follows the development of legislative evaluation practices. Being a legislative technique used not only with the aim of gathering political and social consensus, but also, especially in controversial matters, to provide data and information that will serve as basis for a clarified and justified legislative decision. The characteristic features of the experimental laws are its limited application in time and/or in territory and the prediction, in the law itself, of an evaluation after the experimental period. The application of an experimental law just in a specific geographic area raises constitutional issues because of the implications of the principle of equality. Indeed, the principle of equality, despite admitting some treatment differences between people, commands that these differences have to be legitimate, reasonable and proportional, namely, not arbitrary. Besides the constitutionality problem for the violation of the principle of equality, the experimental laws may also consist of laws restricting fundamental rights and be the cause of the liability of the State, within its legislative function.
