Análisis y modificación de conducta

Resumen tomado de la publicaciónSe examina la eficacia del programa para la reducción del estrés denominado Mindfulness-Based Stress Reduction (MBSR) con un grupo de 28 voluntarios, en su mayoría profesionales de la salud. El 75 por ciento de los participantes completó el programa y el malestar psicológico de estos se redujo en un 49 por ciento según el SCL-90R. El malestar físico también mejoró, con una reducción del 44 por ciento de los síntomas médicos, medidos según el MSCL. Estos resultados son satisfactorios y similares a los citados en otros estudios comparables. Por ello, se piensa que la técnica MBSR puede ser aplicable en España para la reducción del estrés en el ámbito sanitario, con igual efectividad que en Estados Unidos. Esta técnica que se imparte en grupo, con carácter formativo y con un coste reducido, puede ser útil para prevenir riesgos psico-sociales, como el estrés, en los Planes de Prevención de Riesgos Laborales.ValenciaES

The genomic history of the Iberian Peninsula over the past 8000 years

We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia’s ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European–speaking regions but also into non-Indo-European–speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia. Additionally, we document how, beginning at least in the Roman period, the ancestry of the peninsula was transformed by gene flow from North Africa and the eastern Mediterranean.J.M.F., F.J.L.-C., J.I.M., F.X.O., J.D., and M.S.B. were supported by HAR2017-86509-P, HAR2017-87695-P, and SGR2017-11 from the Generalitat de Catalunya, AGAUR agency.
