    Introducción: La enfermedad renal crónica constituye un gran problema de salud pública. Se define como la pérdida progresiva e irreversible de la tasa de filtrado glomerular. La gran mayoría de los pacientes que la sufren requieren un tratamiento renal sustitutivo como puede ser la hemodiálisis. Al tratarse de una terapia muy invasiva conlleva una peor calidad de vida relacionada con la salud, una reducción diaria de actividad física, una menor tolerancia al ejercicio y un deterioro funcional en comparación con el resto de la población. Objetivo: Evaluar los beneficios de un programa de ejercicio físico combinado, aeróbico y de fuerza-resistencia, en pacientes con insuficiencia renal crónica en hemodiálisis propuesto por el Hospital San Juan de Dios de Zaragoza. Metodología: Inicialmente, conformaron la muestra 77 pacientes, todos ellos con participación voluntaria. Aquellos que cumplieron con los criterios de inclusión fueron seleccionados y asignados de manera no aleatoria en dos grupos: 15 pacientes al grupo de ejercicio y 62 pacientes al grupo control. El grupo de ejercicio se incluyó en un programa de ejercicios aeróbicos y de fuerza-resistencia propuesto por el Hospital San Juan de Dios de Zaragoza, mientras que el grupo control recibió el cuidado habitual de hemodiálisis. Se evaluó la calidad de vida de ambos grupos sirviéndonos del cuestionario Kidney Disease Quality of Life – Short Form. Los datos fueron analizados mediante el programa informático IBM SPSS Statistics 25.0. Resultados: Setenta y siete pacientes cumplían con los criterios de inclusión. Hubo diferencias significativas en algunos dominios del cuestionario utilizado en el grupo de ejercicio en comparación con el grupo control. Según el cuestionario, los pacientes del grupo de ejercicio mostraron mejoría en el rol físico (p=0,023) e indicios de mejora en 4 dimensiones: rol emocional, bienestar emocional, salud general y dolor. Por otra parte, se han encontrado diferencias significativas en el dominio función sexual entre ambos grupos. Conclusión: Estos resultados sugieren que la introducción de un programa de ejercicio físico durante la hemodiálisis mejora el rol físico de nuestros pacientes renales.Grado en Enfermerí

    Analytical strategies based on quantum dots for heavy metal ions detection

    Heavy metal contamination is one of the major concerns to human health because these substances are toxic and retained by the ecological system. Therefore, in recent years, there has been a pressing need for fast and reliable methods for the analysis of heavy metal ions in environmental and biological samples. Quantum dots (QDs) have facilitated the development of sensitive sensors over the past decade, due to their unique photophysical properties, versatile surface chemistry and ligand binding ability, and the possibility of the encapsulation in different materials or attachment to different functional materials, while retaining their native luminescence property. This paper comments on different sensing strategies with QD for the most toxic heavy metal ions (i.e., cadmium, Cd2+; mercury, Hg2+; and lead, Pb2+). Finally, the challenges and outlook for the QD-based sensors for heavy metals ions are discussedM.V.G. thanks the MICINN for the PhD grant (FPI, BES-2010-032652).

    Safety of permanent pacemaker implantation: a prospective study

    Get PDF
    Although pacemaker implantation is considered to be low risk, it is not exempt from complications and technical failures during the procedure, both in the short and long term, and the complications that such patients may present remain unknown. The aim has been to analyze the complication rates associated with permanent pacing and to identify if these differ between patients with or without previous antithrombotic therapy. We used a prospective, single center, observational study of 310 adult patients with indications of permanent pacing. They were hospitalized from 1 January to 31 December 2014 and followed up for 6 months after the pacemaker implant. The participants were distributed into two groups according to the antithrombotic therapy prior to the implant. The most frequent major complications were pneumothorax (3.87%) and lead dislodgement (8.39%), while superficial phlebitis (12.90%) and uncomplicated hematomas (22.58%) were presented as the most recurrent minor complications. Hematomas were the most frequent minor complication in the antithrombotic therapy cohort, and shoulder pain was reported as the most recurrent minor complication in the non-exposed group. Finding out about complications in pacemaker implants enables a complete view of the process, and hence the prioritization of actions aimed at improving safety and reducing associated risks

    Modelling Complex Dynamics and Distributed Generation of Knowledge with Bacterial-Based Algorithms

    Get PDF
    This study aimed to test that connected and heterogeneous societies with peer-to-peer (P2P) exchanges are more resilient than centralized and homogeneous ones. In agent-based modeling, agents with bounded rationality interact in a common environment guided by local rules, leading to Complex Adaptive Systems that are named 'artificial societies'. These simplified models of human societies grow from the bottom up in computational environments and can be used as a laboratory to test some hypotheses. We have demonstrated that in a model based on free interactions among autonomous agents, optimal results emerge by incrementing diversity and decentralization of communication structures, as much as in real societies Internet is leading to the emergence of improvements in collective intelligence. In order to achieve a real “Knowledge Society”, what we have named a “P2P Society”, it is necessary to increase decentralization and heterogeneity through information policies, distributed communication networks, open e-learning approaches and initiatives like public domain licenses, free software and open data

    Decentralization and heterogeneity in complex adaptative systems

    Following a bacterial-based modeling approach, the authors want to model and analyze the impact of both decentralization and heterogeneity on group behavior and collective learning. The paper aims to discuss these issues. Inspired by bacterial conjugation, the authors have defined an artificial society in which agents’ strategies adapt to changes in resources location, allowing migration, and survival in a dynamic sugarscape-like scenario. To study the impact of these variables the authors have simulated a scenario in which resources are limited and localized. The authors also have defined three constraints in genetic information processing (inhibition of plasmid conjugation, inhibition of plasmid reproduction and inhibition of plasmid mutation). The results affirmed the hypothesis that efficiency of group adaptation to dynamic environments is better when societies are varied and distributed than when they are homogeneous and centralized.The authors have demonstrated that in a model based on free interactions among autonomous agents, optimal results emerge by incrementing heterogeneity levels and decentralization of communication structures, leading to a global adaptation of the system. This organic approach to model peer-to-peer dynamics in complex adaptive systems (CAS) is what the authors have named “bacterial-based algorithms” because agents exchange strategic information in the same way that bacteria use conjugation and share genome

    Alternative Under Frecuency Load Disconection Methodology Based on Semi-Adaptative Model

    Get PDF
    Stability analysis in electrical power systems is based on the study in dynamic state of the voltage and frequency, since at the moment that there is some contingency it fluctuates drastically due to the primary and secondary controls of the voltage and frequency to the power systems that act on the generators. In order to solve the possible stability problems that may arise in power systems, various techniques have been developed that act on the generating machines for their protection as well as on the loads for the power cut. The present investigation proposes an alternative methodology for load disconnection by low frequency as an option to save the power system from a possible blackout due to instability due to a fall in the frequency, managing to improve the results affected by other improved techniques, the frequency change range, frequency deviation and the effects of demand disconnection. The proposed methodology was tested in the IEEE 14 bus system

    Este breve trabajo pretende analizar en contexto docente universitario la importancia del elemento cultural durante el proceso traductológico, poniendo como ejemplo la traducción del humor en una tipología literaria única: el cómic. A través de la traducción FR-ES de la obra Ab Absurdo, del autor belga Marc Dubuisson, se observarán las peculiaridades presentadas por este formato literario, así como las necesidades adaptativas de los elementos lingüístico-culturales enmarcadas en un contexto de traducción subordinada. La clasificación de tales dificultades, así como la frecuencia de uso de las técnicas empleadas para solventarlas, arrojarán luz sobre la pertinencia de procedimientos más cercanos al método interpretativo-comunicativo, en detrimento de una literalidad que se aleja de la función principal del texto: el humor.This short paper aims to analyse the importance of the cultural element during the translation process in a university teaching context, using as an example the translation of humour in a unique literary typology: the comic. Translating Ab Absurdo from French to Spanish, by the Belgian author Marc Dubuisson, will reveal the special features of this literary format, as well as the adaptive needs of the linguistic-cultural elements framed in a context of subordinate translation. In this case, classify these difficulties and parse the frequency of use in terms of translation techniques employed to solve them will shed light on the relevance of procedures closer to the interpretative-communicative method, to the detriment of a literality that moves away from the main objective of this text: the humour
