Mujer y urología: ¿cuál es la situación en España? / Women in urology: What is their current situation in Spain?

Objetivo Analizar la situación actual de las mujeres en la especialidad de Urología en España. Material y métodos Estudio descriptivo a partir de los resultados de una encuesta electrónica remitida entre febrero y abril de 2020 a través de la base de datos del grupo de Residentes y Jóvenes Urólogos (RAEU) de la Asociación Española de Urología (AEU). Se analizaron las características demográficas de la encuesta y los resultados de la misma. Resultados Se obtuvieron 257 respuestas, correspondientes a 210 mujeres (81,71%) y 47 hombres (18,29%) procedentes de 111 hospitales en total. Se obtuvieron diferencias estadísticamente significativas (p<0,001), con una mayor proporción de hombres en todas las categorías, excepto en el grupo de adjuntas y adjuntos jóvenes (29-39años; p=0,789) y en el de residentes mujeres frente a residentes hombres (p=0,814). En los hospitales con unidades subespecializadas se encontró un mayor número de hombres en todas, excepto en la unidad de suelo pélvico, en la que no se observó una diferencia estadísticamente significativa (p=0,06). Respecto a cargos de responsabilidad, en solo 7 de 111 hospitales había jefas de servicio. Conclusiones La presencia de las mujeres en la especialidad de Urología es cada vez mayor, debido mayoritariamente a las generaciones más jóvenes. Sin embargo, el acceso de estas mujeres a puestos de relevancia es anecdótica (AU)

The number of men was higher in hospitals with subspecialty units except for the Pelvic Floor Unit, where no statistically significant difference was observed (P=.06).

Five-fold symmetry in crystalline quasicrystal lattices.

To demonstrate that crystallographic methods can be applied to index and interpret diffraction patterns from well-ordered quasicrystals that display non-crystallographic 5-fold symmetry, we have characterized the properties of a series of periodic two-dimensional lattices built from pentagons, called Fibonacci pentilings, which resemble aperiodic Penrose tilings. The computed diffraction patterns from periodic pentilings with moderate size unit cells show decagonal symmetry and are virtually indistinguishable from that of the infinite aperiodic pentiling. We identify the vertices and centers of the pentagons forming the pentiling with the positions of transition metal atoms projected on the plane perpendicular to the decagonal axis of quasicrystals whose structure is related to crystalline eta phase alloys. The characteristic length scale of the pentiling lattices, evident from the Patterson (autocorrelation) function, is approximately tau 2 times the pentagon edge length, where tau is the golden ratio. Within this distance there are a finite number of local atomic motifs whose structure can be crystallographically refined against the experimentally measured diffraction data.

Stereospecific dihaloalkane binding in a pH-sensitive cavity in cubic insulin crystals.

Crystallographic analysis at 2-A resolution of the selective binding of dihalogenated methane, ethane, and ethylene compounds in the cavity on the cubic insulin dimer axis provides a model for anesthetic-protein interactions. At pH 6-11, 1,2-dichloroethane binds isomorphically in the right-handed cis-conformation, displacing four water molecules from the invariant cavity. Lowering the pH to 5.7 in 1 M Na2SO4 without dihaloalkanes induces a cooperative structural transition in which the dyad cavities between B13 glutamate pairs are constricted, and SO4(2-) ions are bound by rearranged triads of B1 NH+3 groups. In the presence of dichloroethane at pH 5-5.5, the equilibrium is shifted to a mixture of the ligand-bound and ligand-excluding cavity structures, with half-occupancy of the sulfate sites, exemplifying how a volatile anesthetic can act as an allosteric effector. Measurements at pH 9 of the occupancies of structurally similar dihaloalkanes demonstrate a high degree of binding selectivity. Induced polarization of the ligand and bound water by the charge distribution in the binding cavity apparently provides the selective electrostatic interactions that discriminate between dihaloalkanes of comparable size and polarity.
