Estratigrafia e interpretação paleogeogr��fica do Cenoz��ico continental do norte de Portugal

Palaeogeographic and tectono-sedimentary interpretation of northern Portugal, in which previous studies (geomorphology, lithostratigraphy, mineralogy, sedimentology, palaeontology, etc.) were considered, is here proposed. Cenozoic shows different features according to its morphotectonic setting in the eestern region (Tr��s-os-Montes) or near to the Atlantic coast (western region, Minho and Douro Litoral areas). Although in the eastern region the sedimentary record is considered late Neogene, in some places Paleogene (?) was identified. This oldest record, represented by alluvial deposits, was preserved from complete erosion because of its position inside Bragan��a-Vilari��a-Manteigas fault zone grabens. Later sedimentary episodes (upper Tortonian-Zanclean ?), represented by two allostratigraphical units, were interpreted as proximal fluvial braided systems of an endorheic hydrographic network, draining to the Spanish Duero Basin (eastwards); nowadays, they still remained in tectonic depressions and incised-valleys. Later on, eastern sedimentation becomes scarcer because Atlantic fluvial systems (e.g. the pre-Douro), successively, captured previous endorheic drainages. The proximal reaches of the allostratigraphic unit considered Placencian is recorded in Mirandela (western Tr��s-os-Montes) but the following fluvial episode (Gelasian-early Pleistocene ?) was already documented in east Tr��s-os-Montes, preserved in high platforms and in tectonic depressions. Placencian and Quaternary sedimentary records in the western coastal zone, mainly represented by terraces, are located in the Minho, Lima, Alver��es, C��vado and Ave large fluvial valleys and in the Oporto littoral platform. In conclusion, northern Portugal Tertiary sedimentary episodes were mainly controlled by tectonics, but later on (Placencian-Quaternary) also by eustasy.

Paleoaltera����es e cimenta����es nos dep��sitos continentais terci��rios de Portugal central: import��ncia na interpretação de processos antigos

This paper describes the palaeoweathering, cementation, clay minerals association and other closely related characteristics of central Portugal allostratigraphic Tertiary units (SLD's), that can be used for palaeoclimatic interpretation and palaeoenvironmental reconstruction. Lateral and vertical changes in palaeosols are of value for improving our understanding of the autocyclic and allocyclic controls on sediment acumulation in an alluvial basin, but they can also have stratigraphic importance. In some cases it is concluded that the geomorphological setting may have been more decisive than climatic conditions to the production of the palaeoweathering. During late Palaeogene (SLD7-8), surface and near-surface silicification were developed on tectonically stable land surfaces of minimal local relief under a semi-arid climate; groundwater flow was responsible for some eodiagenesis calcareous accumulations, with the neoformation of palygorskite. Conditions during the Miocene (SLD9-11) were favourable for the smectization of the metamorphic basement and arenization of granites. Intense rubefaction associated with basement conversion into clay (illite and kaolinite), is ascribed to internal drainage during late Messinian-Zanclean (SLD12). During Piacenzian (SLD13) intense kaolinization and hydromorphism are typical, reflecting a more humid and hot temperate climate and important Atlantic fluvial drainage. Later on (Gelasian-early Pleistocene ?; SLD14). more cold and dry conditicns are interpreted, at the beginning of the fluvial incision sage. Silica cementation is identified in the upper Eocence-Oligocene ? (SLD18; the major period of silicification), middle to upper Miocene (SLD10)and upper Tortonian-Messinian (SLD11); these occurrences are compatible with either arid or semi-arid conditions and the establishment of a flat landscape upon which a silcrete was developed.

Estratigrafia sismica do cenoz��ico na plataforma continental algarvia: interpretação do controle tect��nico da sedimenta����o

The interpretation of 64 seismic reflection profiles in the Algarve continental platform (36�� 20'-37�� 00' paralels and 7�� 20'-8�� 40' meridians) calibrated with five petroleum exploration wells, with the identification of the geometric relations between six Cenozoic seismic units (B to G) and tectonic structures, allowed the construction of sucessive time-isopach maps (twt/s) and detailed interpretation of the geologic evolution. Two major tectonic structures were identified: a) the Portim��o-Monchique fracture zone (striking N-S); b) an off-shore NW-SE fault zone, probably the S. Marcos-Quarteira fault. This accident separates two tectonic domains: the western domain (with N-S and E-W predominant structures and, secondarily, NW-SE and NE-SW) and the eastern domain (dominated by WSW-ENE, NW-SE, NE-SW, NNE-SSW and NNW-SSE structures). A persistent halokinetic activity had two major moments: a) sin-C unit; b) sin- and post-E unit. An increasing flexuration of the margin was identified, with spacial and temporal variation of the subsidence. The tectonic regime is considered as generally compressive, but the interpretation of the success��ve stress-fields is rendered dificult by the existence of tectonic sub-domains and evaporitic structures.

Interpretação tect��nica de um conjunto de lineamentos WNW-ESE observados em imagens landsat da margem oeste ib��rica

The existence of satellite images ofthe West Iberian Margin allowed comparative study of images as a tool applied to structural geology. Interpretation of LANDSAT images of the Lusitanian Basin domain showed the existence of a not previously described WNW-ESE trending set oflineaments. These lineaments are persistent and only observable on small scale images (e.g. approx. 11200000 and 11500 000) with various radiometric characteristics. They are approximately 20 km long, trend l200��15�� and cross cut any other families oflineaments. The fact that these lineaments are perpendicular to the Quaternary thrusts of the Lower Tagus Valley and also because they show no off-set across them, suggests that they resulted from intersection oflarge tensile fractures on the earth's surface. It is proposed in this work that these lineaments formed on a crustal flexure of tens ofkm long, associated with the Quaternary WNW-ESE oriented maximum compressive stress on the West Iberian Margin. The maximum compressive stress rotated anticlockwise from a NW -SE orientation to approximately WNW-ESE, from Late Miocene to Quaternary times (RIBEIRO et aI., 1996). Field inspection of the lineaments revealed zones of norm~1.J. faulting and cataclasis, which are coincident with the lineaments and affect sediments of upper Miocene up to Quaternary age. These deformation structures show localized extension perpendicular to the lineaments, i.e. perpendicular to the maximum compressive direction, after recent stress data along the West Portuguese Margin (CABRAL & RIBEIRO, 1989; RIBEIRO et at., 1996). Also, on a first approach, the geographical distribution of these lineaments correlates well with earthquake epicenters and areas of largest Quaternary Vertical Movements within the inverted Lusitanian Basin (CABRAL, 1995).

Fisioterapia : influ��ncia na qualidade de vida da mulher com cancro da mama : contributo para a qualidade do servi��o em oncologia

RESUMO - O cancro da mama �� uma preocupa����o da sa��de p��blica a n��vel mundial, pela sua incid��ncia, mortalidade e custos econ��micos associados. As terapias utilizadas no seu tratamento, embora eficazes, conduzem a altera����es de todas as dimens��es da Qualidade de Vida (QdV) da mulher com cancro da mama. A garantia de uma qualidade de servi��o prestado deve ser uma prioridade das organiza����es de sa��de, sendo a QdV uma medida de resultado. Partindo do pressuposto que em Portugal existe uma diferen��a potencial na forma como as mulheres com cancro da mama recebem o apoio por parte da fisioterapia, importa saber se a fisioterapia tem ou n��o influ��ncia na QdV da mulher com cancro da mama, o que, no caso de ser afirmativo, poder�� constituir uma mais-valia para a qualidade do servi��o prestado em oncologia. O Objectivo deste trabalho �� construir um modelo de an��lise no sentido de responder �� quest��o inicial de investiga����o: ���Ser�� que a fisioterapia contribui para a melhoria da Qualidade de Vida das mulheres com cancro da mama submetidas a cirurgia e outras terapias oncol��gicas?���. Neste sentido o trabalho de projecto dividiu-se por etapas. Inicialmente foi realizado um enquadramento te��rico, atrav��s de uma revis��o de literatura e da realiza����o de entrevistas explorat��rias, permitindo desta forma ter um conhecimento actual das tem��ticas que definem as vari��veis e o objecto de estudo. Na etapa seguinte, foi feita uma an��lise crítica sobre o conhecimento actual do tema em estudo, que permitiu definir as vari��veis a estudar, escolher o instrumento de medida a utilizar, ter conhecimento dos procedimentos a seguir. Ap��s a defini����o do objectivo geral (avaliar se a fisioterapia tem influ��ncia na QdV das mulheres submetidas a cirurgia e outras terapias oncol��gicas) e dos objectivos espec��ficos, iniciou-se o delineamento da metodologia tida como adequada para responder ��s quest��es de investiga����o levantadas (tipo de estudo, as vari��veis, a unidade de an��lise, os m��todos e t��cnicas de recolha de dados, os procedimentos e a metodologia de tratamento de dados). No ��mbito do trabalho de projecto est�� definida a coloca����o em campo de um caso de estudo efectivo que permita dar um contributo real no delineamento da metodologia. Neste trabalho optou-se pela realiza����o de um estudo piloto, que se enquadra nos procedimentos da metodologia e que teve por objectivo retirar algumas conclus��es sobre: a aplicabilidade do instrumento de medida; os tempos definidos para a recolha de dados; as caracter��sticas sociodemogr��ficas e cl��nicas da amostra; as quest��es de investiga����o levantadas. O estudo piloto consistiu num estudo pr��-experimental, com uma amostra de 35 indiv��duos, submetidos a cirurgia a cancro da mama e a outras terapias oncol��gicas. Foram avaliadas as dimens��es do bem-estar f��sico e actividades quotidianas, bem-estar psicol��gico, rela����es sociais, sintomas e caracter��sticas sociodemogr��ficas/cl��nicas, no in��cio do tratamento individual de fisioterapia e no momento de alta. Utilizou-se como instrumento de medida o question��rio EORTC QLQ���30 e o seu question��rio complementar EORTC QLQ���23. Tendo sido constru��da uma ficha para recolha de dados sociodemogr��ficos e cl��nicos. A signific��ncia estat��stica foi aceite para valores de p<0,05. Para compara����o entre grupos e evolu����o dentro de cada grupo aplicou-se o teste t-student e o teste de Mann-Whitney. A an��lise dos resultados do estudo piloto permitiu verificar que: - O instrumento de medida proposto (question��rio EORTC QLQ30 e BR23) mostrou ser de f��cil aplica����o, n��o tendo existido dificuldade por parte das doentes no seu preenchimento. N��o houve problemas no c��lculo dos scores e na sua interpretação; - Parte consider��vel das mulheres com cancro da mama ser�� submetida a protocolos que se poder��o prolongar por v��rios meses ap��s a cirurgia (ex: QT+RT+HT). Esta realidade leva-nos a propor que sejam realizados v��rios momentos de avalia����o, para que possam ser avaliadas as dimens��es da QdV ao longo dos diferentes protocolos de tratamentos. Pensamos que o ideal seria a realiza����o de 4 momentos de avalia����o (3 a 4 semanas ap��s a cirurgia, 3 meses, 6 meses e 9 meses ap��s cirurgia). Sugerimos tamb��m que o estudo proposto seja realizado com uma amostra de maior dimens��o; - O estudo piloto como recorreu a uma metodologia pr��-experimental (aus��ncia de grupo de controlo e apenas dois momentos de avalia����o), n��o permite a consist��ncia dos resultados; no entanto os resultados obtidos podem constituir um indicador de que a fisioterapia tem influ��ncia nas diferentes dimens��es da QdV da mulher com cancro da mama submetida a cirurgia e a outras terapias oncol��gicas, podendo constituir uma mais-valia para a qualidade do servi��o prestado em oncologia. Os resultados do estudo piloto permitiram redefinir a metodologia tida como adequada para responder �� quest��o de investiga����o inicial. Apresentamos de seguida a mesma: Estudo quase-experimental, sendo a amostra constitu��da por dois grupos de 60 mulheres cada, submetidas a cirurgia a cancro da mama e a outras terapias oncol��gicas. O grupo experimental ser�� submetido a tratamentos individuais de fisioterapia. Ser��o avaliadas as dimens��es do bem-estar f��sico e actividades quotidianas, bem-estar psicol��gico, rela����es sociais e sintomas. A recolha de dados ser�� realizada 3 semanas, 3 meses, 6 meses e 9 meses ap��s a cirurgia. Como instrumento de medida ser�� utilizado o question��rio EORTC QLQ���30 e o seu question��rio complementar EORTC QLQ���23, ser��o tamb��m recolhidos dados sociodemogr��ficos e cl��nicos. A signific��ncia estat��stica ser�� aceite para valores de p<0,05. Para compara����o entre grupos e evolu����o dentro de cada grupo ser��o utilizados testes param��tricos e n��o param��tricos. A realiza����o de um estudo que seguisse a metodologia acima referida permitiria uma maior consist��ncia dos resultados, podendo eventualmente existir a confirma����o de que a fisioterapia pode ter influ��ncia na QdV da mulher submetida a cirurgia a cancro da mama e a outras terapias oncol��gicas. A evid��ncia de que a fisioterapia tem influ��ncia na QdV da mulher com cancro da mama, e o facto de a QdV ser um indicador da qualidade do servi��o prestado em oncologia, poder��o constituir um agente facilitador para a mudan��a na gest��o de recursos humanos em organiza����es de sa��de com a val��ncia de oncologia, levando a uma altera����o dos padr��es de pr��tica na ��rea da fisioterapia em oncologia em Portugal, que poder�� conduzir a uma melhor qualidade de servi��o prestado ao doente oncol��gico. ----- ABSTRACT - Breast Cancer is a worldwide public health concern due to the incidence, mortality and economic costs associated. Although effective, therapies used in its treatment lead to changes in all Quality of Life (QoL) dimensions of a woman suffering from Breast Cancer. QoL is an outcome measure, and the insurance of quality of care provided should be a priority to health organizations. Taking into consideration that in Portugal there is a potential difference in the way women with Breast Cancer are provided with physical therapy, it is important to know whether physical therapy does or does not influence the QoL of women with breast cancer. If it does, it will lead to a health care quality improvement to cancer patients. The goal of the following study is to build an analysis model in order to answer the initial investigation question: ���Does Physical Therapy contribute to enhance the Quality of Life of women with breast cancer who underwent surgery and other oncology treatments?��� The project was divided in different stages. Initially, a literature revision was elaborated and exploratory interviews were held, which allowed an actual knowledge of the themes that define the variables and the object of study. The next stage included a critical analysis of the theme, which allowed the definition of variables of study, the choice of instrument of measure and the acquisition of some knowledge on how to proceed. After the definition of the general goal (to evaluate the influence of physical therapy on the QoL of women with breast cancer who underwent surgery and other oncology treatments) and specific goals, the choice of a right methodology took place, in order to answer the investigation questions (type of study, variables, unit analysis, methods and techniques on data collection, procedures and data treatment). In the scope of the project, it is decided to put out on the field an effective case-study which assures a real contribution on the choice of te methodology. In this particular work, there was a pilot study, included in the methodology procedures, with the goal of obtaining conclusions on the applicability of the instrument of measure; the length of time to collect data, the socio-demographic and clinical characteristics of the sample; the investigation questions. The pilot study consisted on a one group pretest-postest design, with a sample of 35 individuals who underwent surgery and other oncology treatments. Dimensions such as physical well-being and everyday life activities, psychological well-being, social relationships, symptoms and socio-demographical/clinical characteristics were assessed at the beginning of physical therapy individual treatment and at the moment of release. The instrument of measure used was the EORTC QLQ���30 questionnaire and its complementary questionnaire EORTC QLQ���23. A chart was made in order to collect socio-demographic and clinical data. Statistic significance was accepted for values of p<0,05. To compare between groups and to detect the evolution within each group, the t-student test and the Mann-Whitney test were applied. The outcome analysis of the pilot study allowed to verify that: - The instrument of measure proposed (EORTC QLQ30 and BR23) was easy to apply, and the subjects did not show any difficulty in filling it up. There was also no problem on calculating the scores or interpreting them; - A considerable part of the women with breast cancer will be submitted to protocols that may occur throughout several months after surgery (e.g., QT+RT+HT). This reality leads us to suggest several moments of assessment of the QoL dimensions in various moments of the different protocol treatments. We consider that the ideal number of evaluations would be 4 (3/4 weeks, 3 months, 6 months and 9 months after surgery). We also suggest the use of a larger sample; - Since the pilot study resorted to a one group pretest-postest design (there is an absence of control group and only two moments of assessment), there is no consistency of outcome. However, the results obtained indicate that physical therapy influences the dimensions of QoL on women with breast cancer who underwent surgery and other oncology treatments, which may be an asset to the quality of care provided to cancer patients. The outcome of the pilot study allowed to redefine the methodology given as adequate to answer the initial investigation question. Our suggestion is as follows: quasi-experimental design, with a sample of 120 subjects (2 groups of 60 women) with breast cancer who underwent surgery and other oncology treatments. The experimental group will be submitted to individual treatments of physical therapy. Dimensions such as physical well-being and everyday life activities, psychological well-being, social relationships and symptoms will be assessed. The collection of data will occur at 3 weeks, 3 months, 6 months and 9 months after surgery. The instrument of measure is the EORTC QLQ���30 questionnaire and its complementary questionnaire EORTC QLQ���23, and social-demographic and clinical information will also be collected. The statistic significance will be accepted for values of p<0,05. Parametric and non-parametric tests will be used to compare between groups and to detect the evolution within each group. Carrying out a study that followed the methodology discussed above would allow a better consistency of results, possibly enabling the confirmation that physical therapy influences the QoL of women with breast cancer who underwent surgery and other oncology treatments. The evidence that physical therapy influences the QoL of women with breast cancer, and the fact that QoL is an indicator of quality of care provided to cancer patients, may work as a facilitating agent in the change of human resources management in health organizations associated to oncology, which will lead to a change in oncology physical therapy practice patterns in Portugal, guiding to a health care quality improvement to cancer patients.
