    Objetivo: Establecer la prevalencia de delirium en pacientes adultos mayores con fractura de cadera en el Servicio de Traumatología del Hospital Universitario Dr. José E. González de octubre del 2008 a mayo del 2009. Métodos: se realizó estudio descriptivo, transversal y prospectivo en la población de pacientes mayores de 60 años con diagnóstico de fractura de cadera en un periodo de ocho meses. Se evaluó delirium mediante el método del estado confusional agudo (CAM) y criterios DSM IV, durante el internamiento y al mes del egreso por vía telefónica. Resultados: Se analizó una población de 74 pacientes con una edad promedio de 79.47 años y primordialmente femenina (74.3%), el promedio de días de estancia fue de 14.68 días, observando prevalencia de delirium del 37.8% y una mortalidad final del 17.6%. No se encontraron diferencias entre ambos grupos, la edad es mayor en los pacientes con delirium y esta correlaciona con la patología (edad promedio: delirium= 84 años / sin delirium= 77 años / p = 0.0016; Rho= 0.347 / p = 0.002). Conclusiones: La prevalencia de delirium encontrada es similar a la reportada en otros estudios. Se observó menor tiempo de estancia hospitalaria, así como una mayor mortalidad en ambos grupos durante su hospitalización, de igual manera, un mes después del ingreso, en el grupo de pacientes que desarrollaron delirium

    Crustal-scale transcurrent fault development in a weak-layered crust from an integrated geophysical research: Carboneras Fault Zone, eastern Betic Cordillera, Spain

    International audienceNew magnetotelluric and receiver transfer function studies provide insights from the upper to the lower crust of the eastern Betic Cordillera, which is deformed by large folds, normal faults, and a major transcurrent left-lateral fault, the Carboneras Fault Zone (CFZ). Receiver function analysis determines a NNW dipping Moho reaching 20 degrees that increases in depth, from 20 km south of the CFZ up to 34 km in the Sierra de Los Filabres. In addition, seismic discontinuities determined in the upper crust are interpreted as major contacts between metamorphic complexes that are detached and folded. The MT inversion model reveals a conductive zone, also representing a crustal seismic discontinuity, associated with the Alpujarride/Nevado-Filabride contact and fitting the N vergent geometry of the Sierra Alhamilla antiform. A small flexure at Moho coincides with the CFZ, as revealed by the Bouguer anomaly trend, in agreement with the receiver function results. Moreover, the Bahr strike and tipper angle at the stations placed closest to the CFZ clearly reveal the continuity of the CFZ at least down to approximately 15 km in depth, crossing all the detected crustal discontinuities up to the Moho. The lack of a clear Moho offset associated with the Carboneras Fault supports the idea that some large strike-slip faults tend to accommodate the deformation by a broadening fault zone at lower crustal levels. Its nucleation could occur at the base of a thin crust, where melting processes critically reduced the lithospheric strength during the late Miocene, to then propagate upward, reaching the topographic surface. Northward, the lithosphere comprised moderately larger strength, and the crustal discontinuities favored the development of larger folds with kilometric amplitude instead of strike-slip faults since the late Miocene
