De la guerra de l'Empordà (1128) a la mortaldat de 1131: gènesi, extensió i extinció d'una fam. Per a una història de les crisis alimentàries a la Catalunya medieval

In the history of food shortages and subsistence crises which affected the Catalan counties during the eleventh and twelfth centuries, the famine of 1129-1131 deserves special mention. Originating in the war of 1128 involving the Empordà and neighboring counties, this famine affected the city of Barcelona and other points of Catalonia (Winter, 1131) and created conditions for the spread of a deadly epidemic (July 1130 -January 1132).

Eventos Adversos Producidos Durante la Asistencia Sanitaria.

El impacto de los Eventos Adversos (EA) durante la asistencia sanitaria es un problema de salud pública de gran actualidad y muy presente a nivel mundial, provocando tres veces más muertes que los accidentes de tráfico. Afecta a todos los niveles sanitarios y perturba de forma relevante la seguridad del paciente. Los objetivos de este trabajo son: conocer la prevalencia de los EA en las unidades asistenciales españolas, comparar el impacto de estos a nivel nacional e internacional, y conocer la forma de notificación así como las estrategias de mejora de los mismos. Para ello, se llevará a cabo una revisión de la literatura bibliográfica en la que se recogerán y se analizaran artículos de carácter científico publicados en revistas indexadas en las bases de datos más consultadas. Se utilizaran artículos escritos tanto en castellano como en inglés, vinculados al área de conocimiento y de interés para esta revisión. Finalmente se han incluido 50 referencias bibliográficas. Así encontramos que los EA en los servicios de hospitalización del ámbito internacional tienen una incidencia máxima de 16.6%, y un 10.11% en España, que aumenta hasta el 25% cuando se trata de unidades especiales. El 4% producen la muerte del paciente. Más del 80% son evitables y el 95% no se notifican. Enfermería es responsable del 33% de EA producidos. Como conclusiones destaca la inexistencia de un mecanismo de prevención eficaz para menguar el impacto de los EA, pese a su gran incidencia. El miedo a represalia y la falta de consciencia de producción del EA por parte de los profesionales de la salud, hacen que se produzca una gran infra-notificación de estos, lo cual dificulta el cumplimiento de las medidas de prevención. Se debe extender la preocupación por el impacto de los EA al ámbito social, sin limitarse solamente al sanitario. Para ello, es necesario concienciar a los profesionales de la salud en primer lugar, trasladándose así a la sociedad en general, con el objetivo de disminuir el impacto en la salud pública de la llamada “Epidemia Oculta de los Errores Sanitarios”.

Sistema de prevenció d'epidèmies en comportaments de risc mitjançant smartphones

L'objectiu d'aquest projecte és desenvolupar una App per Android OS capaç de prevenir a l'usuari de conductes de risc, tenint en compte els senyals WI-FI captats pels diversos smartphones, així com les hipotètiques relacions d'amistat existents entre els contactes de l'agenda.

Allelic diversity and population structure in Vibrio cholerae O139 Bengal based on nucleotide sequence analysis

Comparative analysis of gene fragments of six housekeeping loci, distributed around the two chromosomes of Vibrio cholerae, has been carried out for a collection of 29 V. cholerae O139 Bengal strains isolated from India during the first epidemic period (1992 to 1993). A toxigenic O1 ElTor strain from the seventh pandemic and an environmental non-O1/non-O139 strain were also included in this study. All loci studied were polymorphic, with a small number of polymorphic sites in the sequenced fragments. The genetic diversity determined for our O139 population is concordant with a previous multilocus enzyme electrophoresis study in which we analyzed the same V. cholerae O139 strains. In both studies we have found a higher genetic diversity than reported previously in other molecular studies. The results of the present work showed that O139 strains clustered in several lineages of the dendrogram generated from the matrix of allelic mismatches between the different genotypes, a finding which does not support the hypothesis previously reported that the O139 serogroup is a unique clone. The statistical analysis performed in the V. cholerae O139 isolates suggested a clonal population structure. Moreover, the application of the Sawyer's test and split decomposition to detect intragenic recombination in the sequenced gene fragments did not indicate the existence of recombination in our O139 population.

Taxation of unhealthy consumption of food and drinks: An updated literature review

By means of a literature review this paper aims at shedding more light on the potentialities of unhealthy food/drink taxation in changing eating patterns and life styles and hence combating the obesity epidemic. One remarkable point that emerges when assessing the set of selected papers is the existence of a wide diversity of objectives, methodologies, settings and datasets, policies implemented and results achieved by all these studies, which undoubtedly adds complexity to any attempt to draw a general conclusion on fast food taxation. Most of the examined studies predict a rather modest fiscal impact on unhealthy food and drinks consumption and/or nutrition intake and consequently a poor result on weight loss and obesity, by the interplay of several factors among them the effects of cross-price elasticities.

La desigualdad en el consumo familiar. Diferencias de género en la España contemporánea (1850-1930)

In the last few years, Economic Theory has revised two basic ideas around the economics of the household: that family income is the result of the individual income of each of its members (income pooling), and that all family members living in the household have equal access to its resources. Unequal access to family resources (among women and men, on the one hand, and among the elderly, adults and children, on the other), is now understood as an input (for instance, that women eat less food and of worst quality than men), and as an output (for instance that women have poorer health, higher epidemic mortality, or are less tall than men as a result, among other things, of having received less food and poorer medical care, and/or of a heavier workload). Despite the fact that inequality in intra‐family consumption has become the center of attention in academic and international agencies, it can still not be found in the agenda of Economic History. In this paper we look at some of the resources consumed by Spanish families in the 19th century: food, alcoholic beverages, clothes and shoes. Medical topographies, our main source, suggest that unequal access to family resources among household members had a strong impact on their health and wellbeing.
