Evaluación de la calidad de vida relacionada con la salud mediante las láminas Coop-Wonca en una población de hemodiálisis

Ante la necesidad de disponer de instrumentos que permitan medir calidad de vida relacionada con la salud (CVRS) de una manera ágil y rápida, nos planteamos estudiar, en un grupo de pacientes en hemodiálisis, las propiedades de medición de las láminas Coop-Wonca con el objetivo de establecer si reúnen las condiciones para su uso rutinario en este tipo de pacientes. Métodos: Estudio transversal en 163 pacientes de hemodiálisis (106 varones y 57 mujeres) procedentes de 3 centros. Para medir la CVRS de la población estudiada se ha utilizado la versión validada española de las láminas Coop-Wonca completa. Este cuestionario comprende nueve dimensiones de función y bienestar de un único ítem: 1.– Forma física; 2.–Sentimientos; 3.–Actividades cotidianas; 4.–Actividades sociales; 5.–Cambio en el estado de salud; 6.–Estado de salud; 7.–Dolor; 8.–Apoyo social; y 9.–Calidad de vida en general. Las posibles respuestas se puntúan de 1 a 5, siendo las puntuaciones mayores las que reflejan una peor salud percibida. El instrumento permite la obtención de un índice (Coop total) que es un sumatorio de las puntuaciones de todas las dimensiones salvo la 5 (Cambio en el estado de salud). Resultados: El tiempo medio de cumplimentación del cuestionario fue inferior a 5 minutos. Las láminas resultaron fácilmente comprensibles para los pacientes y la autoadministración de las mismas no planteó problemas. Las puntuaciones más altas (peor CVRS) se obtuvieron en las dimensiones «forma física» (3,66 ± 0,8) y «estado de salud» (3,43 ± 0,8), y la menor (mejor CVRS) en la dimensión «actividades sociales» (1,98 ± 1,3). Entre los principales factores asociados a un peor estado de salud percibida figuran el sexo (mujer), la comorbilidad (presencia de diabetes y/o hepatopatía), la situación laboral (pensionista) y el medio de transporte (taxi-ambulancia). Un mayor tiempo en hemodiálisis se asoció a peores puntuaciones en las dimensiones «calidad de vida en general» y «Dolor». Los pacientes que se trasladaban en taxi o ambulancia presentaban peores puntuaciones en las dimensiones «Forma física», «Actividades cotidianas» y «Estado de salud». Una mayor se asoció a peor puntuación en «Forma física». Un número elevado de fármacos prescritos (más de seis) se asoció a peor puntuación en las dimensiones «Forma física», «Actividades sociales» y «Apoyo social». Los varones, los viudos y los solteros puntuaron peor en «Apoyo social». Los pacientes con mayor nivel de estudios mostraron puntuaciones más altas (peor CVRS) en la dimensión «Forma física». Conclusiones: Las láminas Coop-Wonca podrían ser un buen instrumento de medida de CVRS en los pacientes de hemodiálisis, por la rapidez de su cumplimentación y por ser de fácil comprensión lo que favorece la autoadministración que evita el posible sesgo del entrevistador. Todo ello favorecería su uso rutinario como indicador par valorar la evolución en el tiempo de la CVRS de los pacientes en hemodiálisis. No obstante, se precisan estudios ulteriores que permitan evaluar en mayor profundidad las propiedades psicométricas del instrumento en este tipo de pacientes.

Tensiones y oportunidades en las multinacionales coopitalistas de Mondragón: el caso de Fagor Electrodomésticos, sdad. coop.

Las cooperativas de Mondragon, de acuerdo con su misión, reflejan el esfuerzo de combinar los objetivos de las organizaciones empresariales que compiten a nivel internacional con la creación de empleo, la utilización de métodos democráticos de gestión y el compromiso con el entorno. La multinacionalización de las cooperativas trae consigo nuevas contradicciones, paradojas y dilemas al mundo de la democracia económica. En este artículo se analiza el caso de la cooperativa-multinacional “Fagor Electrodomésticos S. Coop.” de la Corporación Mondragon. Tras años de expansión internacional mediante la inversión directa extranjera, debido a la crisis ha tenido que acometer procesos radicales de restructuración del empleo, tanto en las plantas de la matriz de Mondragón, como en sus empresas filiales extranjeras: la empresa francesa Fagor-Brandt y la antigua empresa comunista polaca Fagor Mastercook. El análisis de las medidas adoptadas para reducir el empleo en Fagor nos servirá de base para profundizar en el conocimiento de las características organizativas de las multinacionales de Mondragon y para reflexionar sobre las posibilidades de extender el modelo cooperativo a las filiales.

Influence of aggregates grading and water/cement ratio in workability and hardened properties of mortars

Mortar is the material responsible for the distribution of stresses in masonry structures. The knowledge about the fresh and hardened properties of mortar is fundamental to ensure a good performance of masonry walls. Water/cement ratio and aggregates grading are among several variables that influence physical and mechanical behaviour of mortars. An experimental program is presented in order to evaluate the influence of aggregates grading and water/cement ratio in workability and hardened properties of mortars. Eighteen compositions of mortar are prepared using three relations cement:lime:sand, two types of sand and three water/cement ratios. Specimens are analyzed through flow table test, compressive and flexural strength tests. Results indicate that the increase of water/cement ratio reduces the values of hardened properties and increases the workability. Besides, sands grading has no influence in compressive strength. On the other hand, significant differences in deformation capacity of mortars were verified with the variation of the type of sand. Finally, some correlations are presented among hardened properties and the compressive strength. (C) 2010 Elsevier Ltd. All rights reserved.

Parametrical study of masonry walls subjected to in-plane loading through numerical modeling

This paper deals with the numerical assessment of the influence of parameters such as pre-compression level, aspect ratio, vertical and horizontal reinforcement ratios and boundary conditions on the lateral strength of masonry walls under in-plane loading. The numerical study is performed through the software DIANA (R) based on the Finite Element Method. The validation of the numerical model is carried out from a database of available experimental results on masonry walls tested under cyclic lateral loading. Numerical results revealed that boundary conditions play a central role on the lateral behavior of masonry walls under in-plane loading and determine the influence of level of pre-compression as well as the reinforcement ratio on the wall strength. The lateral capacity of walls decreases with the increase of aspect ratio and with the decrease of pre-compression. Vertical steel bars appear to have almost no influence in the shear strength of masonry walls and horizontal reinforcement only increases the lateral strength of masonry walls if the shear response of the walls is determinant for failure, which is directly related to the boundary conditions.

Spatial portability of numerical models of leaf wetness duration based on empirical approaches

Leaf wetness duration (LWD) models based on empirical approaches offer practical advantages over physically based models in agricultural applications, but their spatial portability is questionable because they may be biased to the climatic conditions under which they were developed. In our study, spatial portability of three LWD models with empirical characteristics - a RH threshold model, a decision tree model with wind speed correction, and a fuzzy logic model - was evaluated using weather data collected in Brazil, Canada, Costa Rica, Italy and the USA. The fuzzy logic model was more accurate than the other models in estimating LWD measured by painted leaf wetness sensors. The fraction of correct estimates for the fuzzy logic model was greater (0.87) than for the other models (0.85-0.86) across 28 sites where painted sensors were installed, and the degree of agreement k statistic between the model and painted sensors was greater for the fuzzy logic model (0.71) than that for the other models (0.64-0.66). Values of the k statistic for the fuzzy logic model were also less variable across sites than those of the other models. When model estimates were compared with measurements from unpainted leaf wetness sensors, the fuzzy logic model had less mean absolute error (2.5 h day(-1)) than other models (2.6-2.7 h day(-1)) after the model was calibrated for the unpainted sensors. The results suggest that the fuzzy logic model has greater spatial portability than the other models evaluated and merits further validation in comparison with physical models under a wider range of climate conditions.

Rites of passage: Understanding participation of children with developmental coordination disorder

Children with developmental coordination disorder (DCD) experience difficulty participating in the typical activities of childhood and are known to have a more sedentary pattern of activities than their peers. Little research has been done to investigate the impact of these deficits on the lives of children with DCD and the importance of their participation in the typical activities of childhood. This qualitative study explored the impact of the disorder and the importance of participation for children with DCD from the perspective of the parent. Twelve in-depth interviews were conducted with parents of children with DCD who attended a university clinic specializing in using the Cognitive Orientation to daily Occupational Performance (COOP) approach, a cognitive-based intervention. Findings revealed that incompetence in everyday activities had serious negative effects for the children. Conversely, intervention that was focused on enablement at the activity and participation level had a significant positive impact on the children's quality of life. Emerging themes highlighted the notion that performance competency played an important role in being accepted by peers and being able to be part of the group. As well, parents reported that successful participation built confidence in their children and allowed them to try other new activities. The World Health Organization's International Classification of Functioning, Disability, and Health provides a unique framework for analyzing and understanding the impact of the physical disability on the lives of families with children with DCD. Results illustrate how intervention that focuses on enabling children to choose their own functional goals in the area of physical activity has important implications for enabling participation and building the social networks of children with DCD.

Melhortarifa.pt – simulador de tarifários

Assistimos à queda de um serviço, que em muitos países, figurava como um serviço de um modelo social europeu, passando de um monopólio para um sistema de mercado liberalizado e concorrencial: o mercado energético. (EURO COOP, 2014) Em maio de 2014, o mercado livre chegou a ultrapassar os 2,8 milhões de consumidores, tendo um crescimento face a maio de 2013 de 64%, com uma taxa média mensal de 4,2%. (Entidade Reguladora dos Energéticos - ERSE, 2009). Perante a crescente adesão de consumidores para o mercado liberalizado, e suas possíveis futuras mudanças, e tendo em conta com os potenciais clientes a aderirem, foi proposto então construir a plataforma MelhorTarifa.pt . Apesar da já existência de simuladores, estes demonstram-se a ser pouco intuitivos e a não demonstrar toda a informação que o utilizador pretende bem como não existir uma imagem de marca associada a um apoio à mudança de tarifário, tendo sido estas umas das razões que levaram ao desenvolvimento do MelhorTarifa.pt. O âmbito principal deste trabalho, é fornecer uma plataforma informática grátis, imparcial, com o acréscimo até à data, em relação a outros simuladores, da disponibilização de faturas detalhadas sobre o produto que o cliente pretende adquirir, serviços de consultoria, tudo isto de forma rápida e de simples acesso. Com este trabalho pretende-se também definir o atual estado de arte de simuladores idênticos em Portugal e no estrangeiro, pretendendo-se também dar conhecimento do trabalho desenvolvido para esta dissertação, denominado como MelhorTarifa.pt.

CHICKEN COOPS, Triatoma dimidiata INFESTATION AND ITS INFECTION WITH Trypanosoma cruzi IN A RURAL VILLAGE OF YUCATAN, MEXICO

This study longitudinally investigated the association between Triatoma dimidiata infestation, triatomine infection with Trypanosoma cruzi and household/backyard environmental characteristics in 101 homesteads in Molas and Yucatan, Mexico, between November 2009 (rainy season) and May 2010 (dry season). Logistic regression models tested the associations between insect infestation/infection and potential household-level risk factors. A total of 200 T. dimidiata were collected from 35.6% of the homesteads, mostly (73%) from the peridomicile. Of all the insects collected, 48% were infected with T. cruzi. Infected insects were collected in 31.6% of the homesteads (54.1% and 45.9% intra- and peridomiciliary, respectively). Approximately 30% of all triatomines collected were found in chicken coops. The presence of a chicken coop in the backyard of a homestead was significantly associated with both the odds of finding T. dimidiata (OR = 4.10, CI 95% = 1.61-10.43, p = 0.003) and the presence of triatomines infected with T. cruzi (OR = 3.37, CI 95% = 1.36-8.33, p = 0.006). The results of this study emphasize the relevance of chicken coops as a putative source of T. dimidiata populations and a potential risk for T. cruzi transmission.

Evidence of colonization of man-made ecotopes by Triatoma dimidiata (Latreille, 1811) in Costa Rica

Triatoma dimidiata adults have been frequently found, during the last five years, in a dog kennel and a chicken coop, in the back yard of a well-built house, 15 km from San José, the capital of Costa Rica. In the chicken coop nymphs were also found. Two of the 11 dogs from the kennel were serologically positive for Trypanosoma cruzi infection. The inhabitants of the house, three adults and two children, were negative. This type of colonization by the insect, which is attracted to lights, is becoming common in old and new settlements, with different degrees of success, a fact with epidemiological implications and great relevance in the control strategies that can be applied.
