Abstract: background: the impact of each episode of peritonitis on long-term survival of peritoneal dialysis (pd) patients has yet to be defined. objectives: to determine the risk that each episode of peritonitis poses for patient survival and for the pd technique. patients: 1515 patients included in the levante registry from 1 january 1993 to 31 december 2005. methods: retrospective analysis of a multicentre registry using cox regression for time-dependent variables. results: we analysed 1609 episodes of peritonitis in 716 patients (47.2%). in the univariate analysis, each case of peritonitis treated in the outpatient unit was associated with an increase in mortality (hazard ratio [hr] 1.99, p<.001), which was greater for episodes that required hospitalisation (hr 3.62, p<.001). mortality increased with each successive episode in the same patient. multivariate analysis confirmed the association of each case of peritonitis with lower long-term survival (hr 2.01, p<.001), with a different risk for episodes due to gram-positive and gram-negative bacteria and fungi (hr 1.73, 2.43 and 5.71, respectively; p<.001). other variables associated with mortality were age, low residual renal function, absence of vascular access and comorbidity. peritonitis was the only independent variable associated with technique failure (hr 1.29, p<.001), with a different risk for episodes due to gram-positive and gram-negative bacteria and fungi (hr 1.73, 2.43 and 5.71, respectively; p<.001). conclusions: episodes of peritonitis negatively influence long-term survival of patients on pd.

Gómez-Roldán,Andrés;
Vniversitas , 2011,
Abstract: the company acquires a great relevance in its social role towards the society. its responsibility makes it have a special role to public burdens. regulation, the power of inspection, monitoring and control, the state, have caused that the company has a special place in the constitution and the law. the interference of the companies with unsatisfied basic needs, the provision of services, and the impact to consumers and users, demonstrate the need to exert social control over the companies. this paper is a reflection on the role of the company from the delegation viewpoint.
DIMENSIóN DE LA EMPRESA. UNA PROSPECTIVA DE LA EMPRESA EN LA CONSTITUCIóN Y SU IMPACTO SOCIAL DESDE LA DELEGACIóN DIMENSION Of THE COMPANY. A FORESIGHT OF THE ENTERPRISE IN THE CONSTITUTION AND ITS SOCIAL IMPACT, FROM THE DELEGATION VIEWPOINT

Vniversitas , 2011,
Abstract: La responsabilidad de la empresa frente a la sociedad adquiere una gran relevancia, dado que la hace tener un rol especial frente a las cargas públicas que asume día a día frente a los fines del Estado; la regulación, la facultad de inspección, vigilancia y control, que debe tener el Estado, hacen que la empresa tenga un lugar especial en la Constitución y en la ley. La empresa tiene su forma de articularse a la luz de la delegación a nivel interno; la forma en que actúa, su dinámica gerencial, observa la manera en que se delega desde lo público y cómo se creó una tipología de empresas desde la misma Constitución Política; la injerencia de las empresas frente a las necesidades básicas insatisfechas, la prestación de servicios, el impacto en lo ambiental, y su relación con los consumidores y usuarios, ameritan la necesidad de ejercer un control social. Este ejercicio es una reflexión en relación con el papel de la empresa en el marco de la institución de la delegación. The company acquires a great relevance in its social role towards the society.

Portable High Voltage Impulse Generator Generador Portátil de Impulsos de Tensión

Ingeniería e Investigación , 2011,
Abstract: This paper presents a portable high voltage impulse generator which was designed and built with insulation up to 20 kV. This design was based on previous work in which simulation software for standard waves was developed. Commercial components and low-cost components were used in this work; however, these particular elements are not generally used for high voltage applications. The impulse generators used in industry and laboratories are usually expensive; they are built to withstand extra high voltage and they are big, making them impossible to transport. The proposed generator is portable, thereby allowing tests to be made on devices that cannot be moved from their location. The results obtained with the proposed impulse generator were satisfactory in terms of time and waveforms compared to other commercial impulse generators and the standard impulse wave simulator. En este trabajo se presenta un generador portátil de impulsos de tensión, dise ado y construido con un aislamiento hasta para 20 kV. El dise o fue basado en un trabajo previo en el cual se desarrolla un software de simulación implementado exclusivamente para ondas de impulso normalizadas. Los componentes empleados fueron en su totalidad de bajo presupuesto, comerciales y algunos generalmente no son usados en alta tensión. Con el generador de impulsos se obtuvieron resultados satisfactorios en cuanto a tiempos y formas de onda, comparados con otros generadores de impulsos comerciales y el simulador de ondas de impulso normalizadas. Los generadores de impulso utilizados en la industria y laboratorios eléctricos son normalmente de gran tama o, costosos y fabricados para soportar trabajos en extra alta tensión, ocupando demasiado espacio e imposibilitando su transporte. De ahí la importancia de este proyecto, pues siendo portátil facilita realizar pruebas en elementos que no se puedan desplazar de su ubicación.

Abstract: A forest plantation, product of the reforestation of pine trees, represented a pool of biological resources for the implementation of a solid state fermentation process. The trees were identified as Pinus pseudostrobus Lindl from which lignocellulosic material in the form of pine needles was collected. Soil fungi, responsible for plant litter decomposition, were cultured at laboratory conditions and tested for their ability to grow on cellulose and hemicellulose as the sole carbon sources. A fungal strain, belonging to the genus Penicillium, was selected for growing it on pine needles as the substrate in a solid state culture. After following the culture for six days, the newly isolated strain exhibited a much higher capacity for spore production and holocellulose degradation, compared to a purchased strain of Penicillium chrysogenum and two control conditions. This work marks the beginning of future studies focused on commercial applications and represents the first report of a biotechnological process based on pine needles and their degradation by an ascomycetes species belonging to the genus Penicillium.
La lúdica en los procesos democráticos, participativos y pluralistas

Prolegómenos. Derechos y Valores , 2005,
Abstract: La democracia, los principios y valores constitucionales están incluidos en cualquier proceso normativo. Estos mínimos se encuentran también en la lúdica, la cual oxigena el alma de los pueblos, de las personas, de sus comunidades. Una forma diferente de explicar estos contextos es a través de la lúdica, para indicar que en las cosas más simples de nuestra convivencia, estamos siempre jugando, en medio de las reglas de juego que hacen las veces de normas (Constitución), del comportamiento (valores) en el escenario deportivo del juego, como una forma de construir los valores democráticos y llegar con instrumentos novedosos como el juego a impartir la ense anza de la Constitución, de los valores y principios, democráticos, participativos y pluralistas en una nación como la nuestra, que necesita cosas diferentes para explicar cómo funciona lo público estatal y demostrar que el gobierno somos todos

Abstract: 40-80% of cancer patients suffer from diverse degrees of malnutrition, depending on tumor subtype, location and staging and treatment strategy. malnutrition is associated with increased morbidity and mortality in cancer patients. both the high prevalence and prognostic significance of malnutrition imply the need for accurate malnutrition screening in cancer patients, which could select those patients at risk of nutritional derangements who would benefit from nutritional therapy. patient-generated subjective global screening (vsg-gp) remains the reference malnutrition screening method, but its complexity and training requirements prevent wider applicability by oncologists. thus, easier, more clinic-based malnutrition screening tools are required for cancer patients. in this article we propose a basic screening tool based on three items: weight loss, changes in physical activity and decrease in food intake. two affirmative responses out of the three questions is considered as a positive response, and would prompt expert nutritional assessment. results: our screening interview showed positive correlation with vsg-gp (roc 0.85, p<0.001) and allowed for a rapid and accurate identification of patients with cancer-related malnutrition.
