RESUMEN

Resumen Introducción : Las segundas víctimas son aquellos profesionales que, ante un error, quedan traumatizados, cuestionándose sus habilidades profesionales y perso nales. El conocimiento de su experiencia permite a las instituciones entender las consecuencias del error en los profesionales para realizar acciones de atención a los profesionales involucrados mejorando la seguridad de atención. El objetivo de este estudio es caracterizar el fenómeno de segundas víctimas y conocer las medidas de apoyo percibidas. Métodos : Estudio cuantitativo observacional descrip tivo transversal. Participaron profesionales de la salud de cinco instituciones de alta complejidad a través de un muestreo por conveniencia. El instrumento de recogida de datos fue el Second Victim Experience and Support Tool (SVEST) validado en Argentina, compuesta por dimen siones de impacto (psicológico, físico y de habilidades profesionales) de apoyo recibido (colegas, supervisores, institucional y medidas no relacionadas al ámbito la boral) y dos dimensiones de resultado (abandono pro fesional y ausentismo). Resultados : Participaron 1134 profesionales. El 56% manifestó haber cometido un error y completó el SVEST. La media del SVEST fue de 2.5 predominando la dimen sión de impacto psicológico (x = 3.4). Como parte de las medidas de apoyo los profesionales percibieron mayor apoyo en familiares y amigos (x = 3.1). A mayor impacto menor percepción de las medidas de apoyo (Rho: -0.8, p = 0.047). Discusión : Más de la mitad de los profesionales re fieren ser segundas víctimas con un impacto psicológico importante, los cuales, a pesar de trabajar en institu ciones que cuentan con protocolos de seguridad del paciente, reciben el apoyo principalmente de entornos no relacionados al trabajo.

Abstract Introduction : The second victims are those profes sionals who, when faced with a mistake, are traumati zed, questioning their professional and personal skills. Knowledge of their experience allows institutions to understand the consequences of error in professionals to carry out care actions for the professionals involved, improving care security. The objective of this study is to characterize the phenomenon of second victims and to know the perceived support measures. Method : Cross-sectional descriptive observational quantitative study. Health professionals from five highly complex institutions participated through convenience sampling. The data collection instrument was the Second Victim Experience and Support Tool (SVEST) validated in Argentina, composed of impact dimensions (psychologi cal, physical and professional skills) of support received (colleagues, supervisors, institutional and measures not related to the workplace) and two outcome dimensions (professional abandonment and absenteeism). Results : 1134 professionals participated and 56% said they had made a mistake. The mean STEVS was 2.5, with the psychological impact dimension predominating (x = 3.4). As part of the support measures, professionals perceived greater support from family and friends (not re lated to work) (x = 3.1). The greater the impact, the lower the perception of support measures (Rho: -0.8, p = 0.047). Discussion : More than half of the professionals refer to being second victim with a significant psychological impact, who, despite working in institutions that have patient safety protocols, received support from non-work-related environments.

INTRODUCTION: The second victims are those professionals who, when faced with a mistake, are traumatized, questioning their professional and personal skills. Knowledge of their experience allows institutions to understand the consequences of error in professionals to carry out care actions for the professionals involved, improving care security. The objective of this study is to characterize the phenomenon of second victims and to know the perceived support measures. METHOD: Cross-sectional descriptive observational quantitative study.

RESUMEN

Epigenetic regulation is achieved at many levels by different factors such as tissue-specific transcription factors, members of the basal transcriptional apparatus, chromatin-binding proteins, and noncoding RNAs. Importantly, chromatin structure dictates the availability of a specific genomic locus for transcriptional activation as well as the efficiency with which transcription can occur. Chromatin immunoprecipitation (ChIP) is a method that allows elucidating gene regulation at the molecular level by assessing if chromatin modifications or proteins are present at a specific locus. Initially, the majority of ChIP experiments were performed on cultured cell lines and more recently this technique has been adapted to a variety of tissues in different model organisms. Using ChIP on mouse embryos, it is possible to document the presence or absence of specific proteins and chromatin modifications at genomic loci in vivo during mammalian development and to get biological meaning from observations made on tissue culture analyses. We describe here a ChIP protocol on freshly isolated mouse embryonic somites for in vivo analysis of muscle specific transcription factor binding on chromatin. This protocol has been easily adapted to other mouse embryonic tissues and has also been successfully scaled up to perform ChIP-Seq.

RESUMEN

The Myogenic Regulatory Factors (MRFs) Myf5, MyoD, myogenin and MRF4 are members of the basic helix-loop-helix family of transcription factors that control the determination and differentiation of skeletal muscle cells during embryogenesis and postnatal myogenesis. The dynamics of their temporal and spatial expression as well as their biochemical properties have allowed the identification of a precise and hierarchical relationship between the four MRFs. This relationship establishes the myogenic lineage as well as the maintenance of the terminal myogenic phenotype. The application of genome-wide technologies has provided important new information as to how the MRFs function to activate muscle gene expression. Application of combined functional genomics technologies along with single cell lineage tracing strategies will allow a deeper understanding of the mechanisms mediating myogenic determination, cell differentiation and muscle regeneration.
