A propósito del aborto

Tratar adecuadamente en el actual contexto plural la cuestión del aborto, no es oportuno centrarla en torno a los términos matar y no matar, o justo e injusto, sino más bien en un conflicto de valores y de su jerarquización. En ninguna concepción el aborto es un bien, y el reconocimiento del derecho al aborto no implica nunca la obligación de abortar.

Yield of intermittent versus continuous EEG in comatose survivors of cardiac arrest treated with hypothermia.

INTRODUCTION: Electroencephalography (EEG) has a central role in the outcome prognostication in subjects with anoxic/hypoxic encephalopathy following a cardiac arrest (CA). Continuous EEG monitoring (cEEG) has been consistently developed and studied; however, its yield as compared to repeated standard EEG (sEEG) is unknown. METHODS: We studied a prospective cohort of comatose adults treated with therapeutic hypothermia (TH) after a CA. cEEG data regarding background activity and epileptiform components were compared to two 20 minute sEEG extracted from the cEEG recording (one during TH, and one in early normothermia). RESULTS: In this cohort, 34 recordings were studied. During TH, the agreement between cEEG and sEEG was 97.1% (95% CI: 84.6 - 99.9%) for background discontinuity and reactivity evaluation, while it was 94.1% (95% CI 80.3 - 99.2%) regarding epileptiform activity. In early normothermia, we did not find any discrepancies. Thus, concordance was very good during TH (kappa 0.83), and optimal during normothermia (kappa=1). The median delay between CA and the first EEG reactivity testing was 18 hours (range: 4.75 - 25) for patients with perfect agreement and 10 hours (range: 5.75 - 10.5) for the three patients in whom there were discordant findings (P=0.02, Wilcoxon). CONCLUSION: Standard intermittent EEG has comparable performance than continuous EEG both for variables important for outcome prognostication (EEG reactivity) and identification of epileptiform transients in this relatively small sample of comatose survivors of CA. This finding has an important practical implication, especially for centers where EEG resources are limited.

Seizure detection with automated EEG analysis: a validation study focusing on periodic patterns.

OBJECTIVE: To evaluate an automated seizure detection (ASD) algorithm in EEGs with periodic and other challenging patterns. METHODS: Selected EEGs recorded in patients over 1year old were classified into four groups: A. Periodic lateralized epileptiform discharges (PLEDs) with intermixed electrical seizures. B. PLEDs without seizures. C. Electrical seizures and no PLEDs. D. No PLEDs or seizures. Recordings were analyzed by the Persyst P12 software, and compared to the raw EEG, interpreted by two experienced neurophysiologists; Positive percent agreement (PPA) and false-positive rates/hour (FPR) were calculated. RESULTS: We assessed 98 recordings (Group A=21 patients; B=29, C=17, D=31). Total duration was 82.7h (median: 1h); containing 268 seizures. The software detected 204 (=76.1%) seizures; all ictal events were captured in 29/38 (76.3%) patients; in only in 3 (7.7%) no seizures were detected. Median PPA was 100% (range 0-100; interquartile range 50-100), and the median FPR 0/h (range 0-75.8; interquartile range 0-4.5); however, lower performances were seen in the groups containing periodic discharges. CONCLUSION: This analysis provides data regarding the yield of the ASD in a particularly difficult subset of EEG recordings, showing that periodic discharges may bias the results. SIGNIFICANCE: Ongoing refinements in this technique might enhance its utility and lead to a more extensive application.

La enseñanza de la Toxicología en Farmacia: los seminarios como herramienta para la evaluación continuada

Con la finalidad de adaptarnos al EEES, desarrollamos una herramienta que nos permitiera realizar un proceso de evaluación continua de la asignatura troncal de Toxicología. En el presente trabajo presentamos los resultados de este modelo en el que utilizamos los seminarios como elementos básicos de este proceso. Describimos cómo se estructuran y desarrollan estos seminarios, así como el modelo de evaluación de los mismos. Los seminarios fueron evaluados con una puntuación máxima del 30 % sobre la nota final de la signatura, y la participación en los mismos con un máximo del 10 %. Algunos de estos seminarios incorporaban evaluaciones realizadas antes del desarrollo de los mismos, que denominábamos «pre», y otras justo al final del desarrollo de los mismos, que denominábamos «post». Esta herramienta de evaluación continua se ha mostrado muy eficaz en lo que respecta al grado de participación y preparación de los alumnos. Además, ha supuesto un cambio significativo en el grado de implicación de los profesores, y una mejora de la comunicación alumno-profesor.

What makes for peaceful post-conflict elections?

Elections play a crucial role in post-conflict peace and democratization processes as, among other factors, they provide an answer to the question of who is to legitimately rule the country. However, because of the competitiveness arising from their central role in allocating power they can also represent windows of vulnerability where deeply rooted societal conflicts can come to the surface. This working paper focuses on two post-conflict elections (Sierra Leone 2007; Nepal 2008) which, despite perceived high risks, did not result in widespread violence or a return to armed conflict. The aim of these case studies is to identify the factors and measures that may have played an important role in contributing to this outcome. Each of the two case studies first outlines the risks associated with the elections and then analyzes the violence and conflict preventing factors. The paper shows that that the context greatly influences the type of measures that can be taken in such situations, but that there are also some similarities in the two cases studied. In particular, it appears that that the credibility of the elections, largely attributable to a good electoral administration, was an important factor in both Nepal and Sierra Leone. Furthermore, the inclusion of all key stakeholders in decisions regarding key electoral institutions helped to diffuse potential conflict. The study also shows that in both cases the international community played an important role by providing financial, logistical and technical support and by pressuring certain important actors to comply with the rules.

Mudanças e inovações: novo modelo de organização e gestão de biblioteca acadêmica

Descreve-se a reorganização e restruturação da Biblioteca da Faculdade de Saúde Pública da USP, cujo objetivo era alcançar prestação de serviços de qualidade ao usuário do meio acadêmico e profissional em face das novas tecnologias de informática e comunicação e dos novos métodos e processos de trabalho. A implantação do novo modelo iniciou-se em fevereiro de 1997 e se encontra em fase de desenvolvimento, tendo já sido feita a primeira avaliação. Os resultados mostraram que o processo de mudanças é lento, pois as barreiras a serem vencidas não são poucas. Mas a direção que tais mudanças vêm tomando mostram que o modelo de gestão escolhido foi acertado. Resta continuar a desenvolver o modelo, fazendo as correções e melhorando a qualidade dos serviços prestados, que é o objetivo pretendido.

El presente estudio monográfico forma parte de los resultados obtenidos dentro del proyecto de Investigación DGICYT PB 90-0506 "Prospección y análisis de las fases de transición de la Edad del Hierro al mundo romano en el norte de Mallorca, entre la Sierra de Tramuntana y la Sierra de Arta", desarrollado entre los años 1991 y 1994 por el Departamento de Prehistoria, Historia Antigua y Arqueología de la Universidad de Barcelona. El conjunto de materiales analizado incluye los ítems documentados en el yacimiento de Pollentia entre los años 1949 y 1992, procedentes básicamente de las secuencias estratigráficas de las trincheras del área de la muralla occidental, el sector de Sa Portella y la finca de Can Reinés, tratados parcialmente con anterioridad pero carentes hasta la fecha de una análisis global.

High altitude Chironomidae (Diptera) of Serra da Estrela (Portugal): Additions to the Portuguese and Iberian Peninsula fauna

A Chironomidae (Diptera) fauna list for headwater streams of high altitude areas in Serra da Estrela (Portugal) is presented, doubling the previously established species richness for the region. The findings include 17 new records for Portugal, which represent an increase to 219 species for the Continental Portugal Chironomidae fauna. Two new records were detected for the Iberian Peninsula: one species (Tvetenia duodenaria), and one subgenusPsectrocladius (Mesopsectrocladius); and the presence of the genus Natarsia is confirmed. The last two occurrences correspond to monoespecific taxa of the Palearctic region. However, as taxonomic identification has been based on larval material, instead of pupae, pupal exuviae or imagoes, species level assignment is still uncertain. Key words: Diptera, Chironomidae, high mountain streams, Serra da Estrela, Portugal, Iberian Peninsula. RESUMEN Quironómidos (Diptera, Chironomidae) de alta montaña de la Sierra de Estrela (Portugal) y adiciones a la fauna de Portugal y la Península Ibérica Se presenta una lista de especies de Chironomidae (Diptera) recolectados en los ríos de cabecera de zonas de alta montaña en la Serra da Estrela (Portugal). Con esta aportación se duplica la riqueza de especies regional conocida hasta el momento y se eleva la fauna de quironómidos del Portugal continental a 219 especies. Se incluyen dos nuevas citas para la Península Ibérica, una especie (Tvetenia duodenaria) y un subgéneroPsectrocladius (Mesopsectrocladius), y se confirma la presencia del género Natarsia. En los dos últimos casos se trata de larvas de taxones hasta el momento monoespecíficos en la región paleárctica, pero al no haberse recolectado pupas o adultos no se puede asegurar la identificación específica. Palabras clave: Diptera, Chironomidae, ríos de alta montaña, Serra da Estrela, Portugal,

Els fongs de Catalunya occidental segons les prospeccions recents. II

This paper contains the conclusion of a mycological survey of western Catalonia. The first part of the results was published in Acta Bot. Barc. 45 (Homenatge a Oriol de Bolòs): 57-89. The present part covers the last two groups of Basidiomycota: the agarics (326 species) and the gasteromycetes (44 species). The data regarding the surveyed area, collection localities, abbreviations used in the information on ecology, collectors and identifiers are found in the mentioned first part, which contains records of 37 species of Myxomycota, 5 of Zygomycota, 101 of mitosporic fungi, 8 of Teliomycetes, 1 of Ustomycetes, 16 of Phragmobasidiomycetes and 92 of Aphyllophorales. Together with the first part, the results of our survey are a useful contribution to an improved understanding of the fungal component of plant communities of the dry, warm lowlands of the western Mediterranean region, and highlight the remarkable reproductive activity of the fungi observed during late Autumn and Winter, in the studied area.

Els fongs de Catalunya occidental segons les prospeccions recents. I.

The fungi of occidental Catalonia after recent prospections I. This work intends to collect the mycological data gathered during the last four years as a result of the project "Fungal biodiversity of Catalonia", in the western and southern, mainly lowland areas of this country. The climate is mainly dry (400-600 mm/year) and warm. The survey, that covers 160 localities, has enabled the identification of 37 species of Myxomycota, 5 of Zygomycora, 159 of Ascomyctra, 101 mitosporic fungi, 8 Teliomycetes, 1 Ustomycetes, 16 Phragmobasidiomycetes and 92 Apliyllopllorates, that are included in this paper. Because of space limitations, the remaining 326 agarics and 44 Gasteromycetes will be published in the next number of this journal. This work is a contribution to a best understanding of the fungal flora, chorology, ecology and phenology of the West-Mediterranean dry lowlands.
