Contributos para a redução de erros de medicação em pediatria: prescrição electrónica e participação da farmácia

Erros de medicação são um qualquer acontecimento prevenível que pode causar dano no doente quando os medicamentos se encontram sob a responsabilidade dos profissionais de saúde e podem ocorrer em todo o circuito do medicamento. Afectando todos os doentes, apresentam uma maior incidência e gravidade nos doentes pediátricos pelas suas características fisiológicas e comportamentais próprias desta fase do desenvolvimento. Grande parte destes erros podem ser evitados. Um dos elementos que mais tem contribuído para a redução dos erros de medicação em pediatria tem sido a introdução nos hospitais de sistemas de prescrição electrónica (Computerized Prescription Order Entry - CPOE) que, em associação com um maior envolvimento da farmácia no circuito do medicamento, permite uma redução da ocorrência de erros até 81,3%. Objectivo do estudo: verificar, através de uma revisão da literatura, o contributo da utilização da prescrição electrónica em complemento com outras acções desenvolvidas pela farmácia hospitalar na redução de erros de medicação em unidades pediátricas de cuidados intensivos e de emergência

A Bacia do Algarve: estratigrafia, paleogeografia e tectónica

A “Bacia do Algarve” corresponde, segundo a literatura científica tradicional, aos terrenos mesocenozóicos que orlam o Sul de Portugal, desde o Cabo de São Vicente ao rio Guadiana (~140km), penetrando irregularmente para o interior entre 3 km a 25 km, sobre terrenos de idade carbónica da Zona Sul Portuguesa. O hiato, de aproximadamente 70 milhões de anos, materializado pela discordância angular entre as rochas sedimentares de tipo flysch do Carbónico, metamorfizadas e deformadas durante a orogenia varisca, e as rochas sedimentares continentais do Triásico inferior provável, separa dois ciclos de Wilson. Os sedimentos carbónicos metamorfizados resultam do empilhamento orogénico de um possível prisma de acrecção associado à orogenia varisca e ao fecho de um oceano paleozóico e formação da Pangeia, enquanto que os sedimentos continentais triásicos resultam do fim do colapso e do arrasamento do orógeno varisco e início do estiramento continental que viriam a culminar com a separação das placas litosféricas África, Eurásia e América.Os sedimentos mais recentes do Mesozóico e os mais antigos bem datados do Cenozóico encontram-se separados por um outro hiato que ultrapassa ligeiramente os 70 milhões de anos na área emersa. Este hiato resulta duma alteração tectónica radical no contexto onde nessa época geológica se inseria a Bacia do Algarve. Esta mudança, que ocorreu no fim do Cenomaniano, resultou da rotação do vector de deslocamento da trajectória de África em relação à Eurásia, de aproximadamente NW-SE para SW-NE (segundo as coordenadas actuais, e.g. Dewey et al, 1989), poria termo ao regime distensivo e de bacia de tipo rifte na Bacia do Algarve, com o fim do regime transtensivo entre a região noroeste da placa África e sudoeste da placa Eurásia e início da colisão

The role of climate, marine influence and sedimentation rates in late-Holocene estuarine evolution (SW Portugal)

Estuaries are sensitive to changes in global to regional sea level, to climate-driven variation in rainfall and to fluvial discharge. In this study, we use source and environmentally sensitive proxies together with radiocarbon dating to examine a 7-m-thick sedimentary record from the Sado estuary accumulated throughout the last 3.6 kyr. The lithofacies, geochemistry and diatom assemblages in the sediments accumulated between 3570 and 3240 cal. BP indicate a mixture between terrestrial and marine sources. The relative contribution of each source varied through time as sedimentation progressed in a low intertidal to high subtidal and low-energy accreting tidal flat. The sedimentation proceeded under a general pattern of drier and higher aridity conditions, punctuated by century-long changes of the rainfall regime that mirror an increase in storminess that affected SW Portugal and Europe. The sediment sequence contains evidence of two periods characterized by downstream displacement of the estuarine/freshwater transitional boundary, dated to 3570-3400 cal. BP and 3300-3240 cal. BP. These are intercalated by one episode where marine influence shifted upstream. All sedimentation episodes developed under high terrestrial sediment delivery to this transitional region, leading to exceptionally high sedimentation rates, independently of the relative expression of terrestrial/marine influences in sediment facies. Our data show that these disturbances are mainly climate-driven and related to variations in rainfall and only secondarily with regional sea-level oscillations. From 3240 cal. BP onwards, an abrupt change in sediment facies is noted, in which the silting estuarine bottom reaches mean sea level and continued accreting until present under prevailing freshwater conditions, the tidal flat changing to an alluvial plain. The environmental modification is accompanied by a pronounced change in sedimentation rate that decreased by two orders of magnitude, reflecting the loss of accommodation space rather than the influence of climate or regional sea-level drivers.FCT by Spanish Ministry of Science and Innovation [SFRH/BD/110270/2015, HAR2014-51830-P, HAR2011-29907-C03-00]FCTPortuguese Foundation for Science and Technology [PTDC/HISARQ/121592/2010]Instituto Dom Luiz-IDL [UID/GEO/50019/2013]info:eu-repo/semantics/publishedVersio

The national inventory of geological heritage: methodological approach and results

A existência de um inventário nacional de património geológico é fundamental para se poderem implementar estratégias de geoconservação. Este trabalho apresenta a metodologia usada no desenvolvimento do mais completo inventário de geossítios, realizado até ao momento em Portugal, assim como os principais resultados obtidos. O inventário vai integrar o Sistema de Informação do Património Natural e o Cadastro Nacional dos Valores Naturais Classificados, ambos geridos pelo Instituto de Conservação da Natureza e da Biodiversidade.The existence of a national inventory of the geological heritage is of paramount importance for the implementation of a geoconservation strategy. This paper presents the methodological approach used to produce the most complete geosites inventory in Portugal, so far, and the obtained results. This inventory will be uploaded into the National Database of Natural Heritage managed by the Portuguese authority for nature conservation.Este trabalho é apoiado pela Fundação para a Ciência e a Tecnologia, através do financiamento plurianual do CGUP e do projecto de investigação “Identificação, caracterização e conservação do património geológico: uma estratégia de geoconservação para Portugal” (PTDC/CTE-GEX/64966/2006).info:eu-repo/semantics/publishedVersio

Experimental evidence for the species character of Calcidiscus leptoporus

ABSTRACT—Culturing experiments of the intermediate morphotype of the cosmopolitan coccolithophore Calcidiscus leptoporus, indicate that the size of its coccosphere and of its coccoliths are affected only in a minor way by temperature. The changes observed in clones growing under different temperature and light conditions are within the range defined for this morphotype in the plankton and Holocene sediments. This outcome suggests that the three morphotypes of living C. leptoporus may be reproductively isolated species rather than stages in a life cycle of a single species or ecophenotypic adaptations of a single species with considerable morphological plasticity. Numerous extinct morphotypes of C. leptoporus have been recorded from marine sediments deposited during the last approximately 25 Ma. In the light of our experiments, these may in fact represent genetically distinct species, which experienced rapid evolution

The Palaeontological Heritage of Santa Maria Island (Azores: NE Atlantic): a Re-evaluation of Geosites in GeoPark Azores and Their Use in Geotourism

The application of geoconservation concepts and methodologies to the Azores archipelago led to the implementation of the Geopark Azores, recognized as such by the European and Global Geoparks Network. The current work re-evaluates and stresses the scientific and touristic value of the palaeontological sites of Santa Maria Island. Two new geosites (the Ponta do Castelo tempestite deposit and the Pedra-que-pica coquina) are proposed for classification as ‘Regional Natural Monuments’ by the Regional Government of the Azores, due to their international relevance. The tempestite deposit of Ponta do Castelo was overlain by a contemporary coastal lava delta, which enables the inference of the precise water depth of the geosite at the time of deposition, a very rare condition worldwide; and Pedra-que-pica is the most extensive multispecific fossiliferous coquina ever reported in the literature from the shelf of any of the ∼20,000 known volcanic oceanic islands in the world. Relevant geosites reported for this island are increased from 15 to 26. Additional palaeontological heritage contributions to the sustainable tourism of Santa Maria are suggested, with a focus on two recent projects: the ‘Fossil Trail’ and the future ‘PalaeoPark Santa Maria’

Role of environmental change in rock-boring echinoid trace fossils

Well preserved groove-borings related to the boring activity of regular sea urchins are preserved on Neogene rocks associated with rocky palaeoshores in a volcanic oceanic island (Santa Maria, Azores archipelago) and a continental margin (Foz da Fonte, Central West Portugal). The new trace fossil consists of a series of relatively deep grooves, with sinuous pathway and with a fairly uniform width along its trajectory. A series of forward oriented concave markings occur frequently inside the grooves, reflecting the movement direction of the producer. The trace fossil is designated as Ericichnus igen. n. with two new ichnospecies, Ericichnus bromleyi isp. n. and Ericichnus asgaardi isp. n. Ericichnus igen. n. could have been produced by regular echinoids, similar to the extant echinometrid echinoid Echinometra lucunter (Linnaeus, 1758) for E. bromleyi isp. n. and similar to the echinid Paracentrotus lividus Lamarck, 1816 for E. asgaardi isp. n. Ethologically, the compound trace fossil Ericichnus igen. n-Circolites may correspond to an agrichnion–pascichnion and/or domichnion. Our study suggests that the new ichnospecies E. bromleyi may be used as a palaeoenvironmental tool, indicating the boring activity of termophile rock-boring echinoids in the fossil record
