En nuestro medio, el linfedema más frecuente es el que aparece en el miembro superior tras los tratamientos del cáncer de mama. Existe un interés creciente acerca de su impacto sobre la Calidad de Vida, entendida ésta como el completo estado de bienestar físico, mental y social de la persona. Para poder medir la CV en esta población, se precisan herramientas específicas, dado que los cuestionarios genéricos no recogen las particularidades de esta enfermedad. El cuestionario ULL-27 (Upper limb lymphedema) fue la primera escala específica desarrollada para valorar la calidad de vida de mujeres con linfedema de miembro superior tras cáncer de mama1. Dada la necesidad de disponer de este tipo de instrumentos en nuestro país, y habiendo mostrado el cuestionario francés ULL-27 buenas propiedades psicométricas en su estudio de validación, se planteó como objetivo su traducción al español y adaptación transcultural a nuestro medio, procediendo a continuación a su validación en una muestra de mujeres con linfedema de miembro superior tras cáncer de mama...

The Upper Miocene stratigraphic succession of the Las Minas Basin, located at the external zone of the Betic Chain in SE Spain, preserves several examples of lake carbonate bench deposits. Excellent exposures of the carbonate benches allow detailed observation of the architecture of these sediments and provide new insights for the ‘‘steep-gradient bench margin–low energy’’ model proposed by Platt and Wright (1991). The lake carbonate benches developed in close association with fluvially dominated shallow deltas that exhibit typical Gilbert-type profiles. The delta sequences comprise bottomset prodelta marl facies, distal to proximal foreset facies, deposited mainly in a delta-front environment, and topset facies, the latter reflecting both subaqueous delta-front and subaerial delta-plain environments. The development of the carbonate benches was constrained by the convexupward morphology of the deltaic deposits, which led to the available accommodation space for the growth of the steep-gradient platforms. The benches display a progradational pattern characterized by sigmoid-oblique internal geometries and offlap upper boundary relationships, which suggests that the carbonate benches developed under slow though continuous lake-level rise. Both the dimensions of the benches and the dominant carbonate components (i.e., encrusted charophyte stems and calcified cyanobaterial remains), allow comparisons with the progradational marl benches recognized in modern temperate hardwater lakes. Accordingly, the case study presented here provides a good ancient sedimentary analog for low-energy lake carbonate benches. Moreover, the evolutionary trend inferred from the fossil example offers new insights into the depositional conditions of this type of sediment and allows recognition of the transitional pattern from bench to ramp carbonate lake margins.
