Estudio de la incidencia de ampollas en el "trekking" y sus factores asociados

Objetivo: Determinar los factores asociados con la presencia de ampollas durante el senderismo. Método: La población de estudio fueron 1155 peregrinos que recibieron asistencia podológica. La información fue obtenida mediante una anamnesis y una exploración podológica. Los factores analizados fueron: edad, sexo, entrenamiento previo, nacionalidad, tipo de calzado, antigüedad del mismo y kilómetros realizados. Resultados: Las ampollas se encontraron en el 71,9 % de los peregrinos y se distribuyeron de manera similar en ambos pies, afectando principalmente el talón (20%) y el quinto dedo (14,6 %). Se encontró asociación con el sexo (p < 0,05). Las deportivas fueron las menos asociadas con ampollas (p = 0,03). No hubo relación significativa con el entrenamiento previo y el uso de calzado nuevo. Conclusiones: La incidencia de ampollas entre los senderistas fue del 80 %, y se asoció con el sexo (mayor en la mujer) y el tipo de calzado.

La Inteligencia Competitiva en los procesos de internacionalización empresarial: Una guía de recursos de información para la empresa española y el periodismo económico

La información se ha convertido en un recurso imprescindible para el proceso de toma de decisiones en las empresas, y elemento fundamental en el proceso de Inteligencia Competitiva. La globalización económica y la libre circulación de mercancías, bien sea dentro de estructuras supranacionales o derivados de la firma de Tratados internacionales, han aumentado el número de competidores presentes en los mercados, pero también las oportunidades para acceder a otros mercados internacionales. Este trabajo describe los recursos de información más importantes que puede necesitar una empresa en su acceso a los mercados internacionales, y que proceden tanto de organismos públicos como privados.

Evaluation of a Water-soluble Bioadhesive Patch for Photodynamic Therapy of Vulval Lesions

An innovative bioadhesive patch intended primarily as a vulval drug delivery system and, specifically, as a means to deliver photosensitisers, or their prodrugs, for photodynamic purposes is described. The patch was formulated with a copolymer of methyl vinyl ether and maleic anhydride (PMVE/MA) as a bioadhesive matrix and poly(vinyl chloride) as a drug-impervious backing layer. Adhesive strength to neonate porcine skin, as a model substrate, was evaluated using peel and tensile testing measurements. Acceptabilities of non-drug loaded patches were appraised using human volunteers and visual-analogue scoring devices. An optimal formulation, with water uptake and peel strengths appropriate for vulval drug delivery, was cast from a 20% (w/w) PMVE/MA solution and adhered with a strength of approximately 1.7 N cm-2. Patient evaluation demonstrated comfort and firm attachment for up to 4 h in mobile patients. Aminolevulinic acid, a commonly used photosensitiser, was formulated into the candidate formulation and applied to vulval intraepithelial neoplastic lesions. Fluorescence under ultraviolet illumination revealed protoporphyrin synthesis. The patch achieves the extended application times obligatory in topical photodynamic therapy of vulval lesions, thereby contributing to potential methods for the eradication of neoplastic lesions in the lower female reproductive tract.

Fast and frugal models of clinical judgement in novice and expert physicians

Our objective was to study whether “compensatory” models provide better descriptions of clinical judgment than fast and frugal models, according to expertise and experience. Fifty practitioners appraised 60 vignettes describing a child with an exacerbation of asthma and rated their propensities to admit the child. Linear logistic (LL) models of their judgments were compared with a matching heuristic (MH) model that searched available cues in order of importance for a critical value indicating an admission decision. There was a small difference between the 2 models in the proportion of patients allocated correctly (admit or not-admit decisions), 91.2% and 87.8%, respectively. The proportion allocated correctly by the LL model was lower for consultants than juniors, whereas the MH model performed equally well for both. In this vignette study, neither model provided any better description of judgments made by consultants or by pediatricians compared to other grades and specialties.

Discourses of equality in post-Agreement Northern Ireland

This article analyses the use of equality as a concept central to the implementation of the 1998 Good Friday Agreement in Northern Ireland. The authors argue that, although equality legislation is succeeding in redressing previous discrimination in society, the discourses that have emerged around it have exacerbated competition and polarization between communities for two main reasons. Firstly, in " selling' the Agreement to their supporters, political elites have appropriated community-specific definitions of the concept, thus reinforcing rather than weakening group differences. Secondly, the practice of equality legislation involves the definitive categorization of individuals as members of particular groups. This article examines these processes and their effects through the analysis of the discourse of nationalist and Unionist Party elites and of individual Catholics and Protestants. This is done in order to capture the dynamics of change in political communication and identification rather than simply describing institutional alterations.

Family-based investigation of the C677T polymorphism of the methylenetetrahydrofolate reductase gene in ischaemic heart disease

Background: Elevated homocysteine is associated with ischaemic heart disease (IHD). The C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene results in reduced MTHFR enzyme activity and reduced methylation of homocysteine to methionine resulting in mild hyperhomocysteinaemia. Case-control association studies of the role of the C677T MTHFR polymorphism in IHD have produced conflicting results. We therefore used newly described family-based association tests to investigate the role of this polymorphism in IHD, in a well-defined population. Methods: A total of 352 individuals from 129 families (discordant sibships and parent-child trios) were recruited. Linkage disequilibrium between the polymorphism and IHD was tested for using the combined transmission disequilibrium test (TDT)/sib-TDT and pedigree disequilibrium test (PDT). Homocysteine levels were measured. Results: Both the TDT/sib-TDT and PDT analyses found a significantly reduced transmission of the T allele to affected individuals (P=0.016 and P=0.021). There was no significant difference in homocysteine levels between affected and unaffected siblings. TT homozygotes had mean homocysteine levels significantly higher than those of TC heterozygotes (P

Towards a Stronger Conception of Democracy in the Strasbourg Convention

The purpose of this article is to examine the promotion of democracy through human rights law. The focus will be on the possibilities for using the European Convention on Human Rights to promote participatory democracy. The author argues that the jurisprudence of the Strasbourg Court is beginning to recognise some participatory measures such as the requirement of consultation, notably under Article 8 of the Convention.

Cybr, a cytokine-inducible protein that binds cytohesin-1 and regulates its activity

Cytokines regulate lymphocyte development and differentiation, but precisely how they control these processes is still poorly understood. By using microarray technology to detect cytokine-induced genes, we identified a cDNA encoding Cybr, which was increased markedly in cells incubated with IL-2 and IL-12. The mRNA was most abundant in hematopoietic cells and tissues. The predicted amino acid sequence is similar to that of GRP-1-associated protein (GRASP), a recently identified retinoic acid-induced cytohesin-binding protein. Physical interaction, dependent on the coiled-coil domains of Cybr and cytohesin-1, was demonstrated by coimmunoprecipitation of the overexpressed proteins from 293T cells. Cytohesin-1, in addition to its role in cell adhesion, is a guanine nucleotide-exchange protein activator of ARF GTPases. Acceleration of guanosine 5'-O-(thiotriphosphate) binding to ARF by cytohesin-1 in vitro was enhanced by Cybr. Because the binding protein modified activation of ADP ribosylation factor by cytohesin-1, we designate this cytokine-inducible protein Cybr (cytohesin binder and regulator).
