Efectividad de la Escala de WOMAC para evaluar los resultados funcionales de los pacientes sometidos a Artroplastía total de Rodilla por diagnostico de Gonartrosis primaria grado III y IV de la Clasificación de Kallgren y Lawrence en el Centro Médico Lic. Adolfo López Mateos

El tratamiento para los grados III y IV de gonartrosis primaria de la clasificación de Kellgren y Lawrence es mediante la artroplastia total de rodilla. Actualmente los avances en el campo de la ingeniería y la mejora de los materiales han permitido desarrollar nuevos implantes de rodilla, que pretenden reproducir con mayor exactitud la cinemática de la rodilla sana y de esta forma alcanzar una máxima función por lo que es fundamental una evaluación postquirúrgica mediante un método práctico y eficaz como lo es, la escala de WOMAC. Objetivo: Presentar una forma sencilla práctica y económica para la valoración de la función de la rodilla, posterior a una artroplastia total. Material y métodos: Se realizó un estudio Transversal, observacional, descriptivo y retrospectivo, que incluyó a 39 pacientes que fueron sometidos a reemplazo articular total de rodilla primaria de más de 3 meses a 3 años de post operados de marzo 2012 a febrero 2013, se valoró la funcionalidad de acuerdo a la escala de WOMAC (Puntuación del Índice de Osteoartritis Western Ontario y Macmaster). Resultados: Se observó de acuerdo a la escala, 22 pacientes (56.4%) obtuvieron buenos resultados, con una media de 19 puntos, mediana de 20.3, moda de 15 - 24 puntos. Excelentes resultados en 14 pacientes (35.8%) con una media de 10.4 puntos, mediana de 11, moda de 3, los resultados aceptables 2 pacientes (5.1%) y un mal resultado que es un 2.5%. Conclusiones: La escala de WOMAC es un instrumento útil para evaluar los resultados funcionales de los pacientes post operados de artroplastia total de rodilla primaria, al ser una herramienta práctica reproducible, económica, sin requerir de estudios especiales, la cual se puede aplicar a distintos niveles de atención, identificar las complicaciones e incidir en ellas oportunamente y mejorar los resultados

Docencia de arquitectura orientada a servicios

Este trabajo presenta los contenidos del curso “Web 2.0: Arquitectura Orientada a Servicios en Java” de la Escuela de Posgrado de la Universidad de Granada. El objetivo del curso es familiarizar al alumno con la programación de ServiciosWeb. Dada la gran variedad de técnicas disponibles para utilizar Arquitectura Orientada a Servicios, se presentan los siguientes temas: utilización de protocolos bien definidos para comunicación y contrato (SOAP y WSDL), creación de Web Services con JAX-WS y orquestación de ServiciosWeb con BPEL. Al final del curso, el alumno será capaz de crear, utilizar y mantener Servicios Web para el desarrollo de aplicaciones interempresariales, utilizando servicios creados o ya disponibles en la web, así como la orquestación lógica de los mismos.SUMMARY: This work presents the contents of the course “Web 2.0: Service Oriented Architecture on Java” from the Graduate School of the University of Granada. The course objective is to familarize students with Web Services programming. Due to the wide variety of available technologies, several subjects are presented: the usage of well-defined protocols to contract and communication (SOAP and WSDL), web services creation using JAX-WS, and service orchestration with BPEL. At the end of the course, students will be capable to create, use and manage Web Services for business applications, using new or available services in the web, and also their logical orchestration.Peer Reviewe

Robust Tracking of Bio-Inspired References for a Biped Robot Using Geometric Algebra and Sliding Mode Control

Controlling walking biped robots is a challenging problem due to its complex and uncertain dynamics. In order to tackle this, we propose a sliding mode controller based on a dynamic model which was obtained using the conformal geometric algebra approach (CGA). The CGA framework permits us to use lines, points, and other geometric entities, to obtain the Lagrange equations of the system. The references for the joints of the robot were bio-inspired in the kinematics of a walking human body. The first and second derivatives of the reference signal were obtained through an exact robust differentiator based on high order sliding mode. The performance of the proposed control schemes are illustrated through simulation.ITESO, A.C

Experimental energy performance assessment of a solar desiccant cooling system in Southern Europe climates

Solar desiccant cooling systems, SDEC, could be an effective alternative to conventional cooling systems, which mainly depend on electrical energy. The main objective of this work was to determine experimentally the seasonal coefficient of performance, SCOP, of a SDEC system composed of a desiccant wheel, an indirect evaporative cooler and a thermal solar system, to control indoor conditions in a research lab room. The dependence of coefficient of performance on outdoor air conditions and percentage of renewable energy used by the SDEC system were also analysed. Experimental tests were carried out for six weeks during spring and summer seasons in Martos, Spain. The experimental results showed that the SDEC system independently adjusted the temperature and humidity of the supply air. 75% of the energy consumed by this air handling system comes from renewable sources. A seasonal coefficient of performance of the SDEC system of 2 was obtained for the period analysed. It is shown that the higher the outdoor temperature, the higher instantaneous COPs is. These results suggest that the use of SDEC systems in hot climates, such as southern European climates, could contribute to achieve the EU's energy goals within the frame of Nearly Zero Energy Buildings

Distribución de metales pesados en sedimentos de las marismas del Odiel (Huelva, España)

Se ha analizado la distribución y contenido total de metales pesados (Co, Cu, Fe, Mn, Ni y Pb) en sedimentos de las Marismas del Odiel (SO España). Las concentraciones de estos elementos, obtenidas por espectrofotometría de absorción atómica, fueron muy elevadas para la mayoría de los elementos analizados. Su distribución no es homogénea, ni presenta un patrón geográfico marcadamente definido, pudiéndose encontrar altos niveles repartidos por toda la marisma. Existe cierto gradiente topográfico, con mayores concentraciones en puntos de menor cota. Los puntos de muestreo más aislados de la incidencia mareal y los más expuestos a mar abierto registraron los niveles más bajos.Atomic absorption spectroscopy has permitted the determination of the content of heavy metals and their distribution in sediments of the Odiel Saltmarhes (SWSpain). Avery high metal concentration has been found in most of the samples investigated but their distribution is non-homogeneous and this prevents establishing a geographical pattern. Nevertheless, a certain topographic gradient can be observed: lower levels present the highest concentrations whereas areas unaccessible by tide fluctuations or those exposed to the sea present the lowest index of contamination

The Minor Allele of rs7574865 in the STAT4 Gene Is Associated with Increased mRNA and Protein Expression

We studied 201 patients (80% female; median age, 54 years; median disease duration, 5.4 months) from PEARL study. Demographic, clinical, laboratory and therapeutic data were collected at each visit. IL-6 serum levels were measured by enzyme immune assay. The rs7574865 was genotyped using TaqMan probes. The expression levels of STAT4 mRNA were determined at 182 visits from 69 patients using quantitative real-time polymerase chain reaction. STAT4 protein was assessed by western blot in 62 samples from 34 patients. To determine the effect of different variables on the expression of STAT4 mRNA and protein, we performed multivariate longitudinal analyses using generalized linear models.This work was supported by grants awarded to IGA from the RETICS Program (RD08/0075/0004 and RD12/0009/0017 [RIER]) and FIS Program (PI11/0551) and to JM from RETICS Program (RD08/0075/0011 and RD12/0009/0004 [RIER]) from the Instituto de Salud Carlos III (www.isciii.es).
