Síndrome de quemarse por el trabajo (burnout) en los médicos de España.
El Síndrome de Quemarse por el Trabajo (SQT) o "Burnout" es un problema de salud que puede afectar a profesionales de todo tipo, pero muy especialmente a aquellos cuya actividad guarda relación con el cuidado de seres humanos. Los profesionales de la salud están particularmente expuestos a este cuadro y los médicos son el prototipo de trabajador expuesto al mismo. Se trata de un problema de salud tremendamente destructivo que afecta a la vida laboral y personal, que lesiona la calidad del trabajo prestado y que deteriora los planos cognitivo y emocional del individuo, su vida familiar y hasta su salud física.
Whole genome sequencing-based analysis of tuberculosis (TB) in migrants: rapid tools for cross-border surveillance and to distinguish between recent transmission in the host country and new importations

Subtle genotypic changes can be observed soon after diagnosis in Mycobacterium tuberculosis infection.
Clonal variants of Mycobacterium tuberculosis (MTB) coexist in specific patients, although the dynamics of their emergence is unknown. We used MIRU-VNTR to detect microevolution leading to variants of MTB in 3 out of 19 patients (15%) soon after diagnosis (61-85 days). Most harbored SNPs and for some of them a potential functional role was suggested. Microevolution in tuberculosis seems to occur sooner and more often than expected and could affect tracking of transmission.
Whole genome sequencing analysis of intrapatient microevolution in Mycobacterium tuberculosis: potential impact on the inference of tuberculosis transmission.
Background. It has been accepted that the infection by Mycobacterium tuberculosis (M. tuberculosis) can be more heterogeneous than considered. The emergence of clonal variants caused by microevolution events leading to population heterogeneity is a phenomenon largely unexplored. Until now, we could only superficially analyze this phenomenon by standard fingerprinting (RFLP and VNTR).Methods. In this study we applied whole genome sequencing for a more in-depth analysis of the scale of microevolution both at the intrapatient and interpatient scenarios.Results. We found that the amount of variation accumulated within a patient can be as high as that observed between patients along a chain of t…
Genotyping of a nosocomial outbreak of pandemic influenza A/H1N1 2009
Background: Epidemiological surveys have revealed outbreaks of pandemic influenza A (H1N1) 2009 in several different contexts. Molecular characterization of the influenza virus could help to provide a more accurate description of these outbreaks. Objective: To genotype pandemic influenza A (H1N1) 2009 isolates from an epidemiologically defined nosocomial outbreak. Study design: We sequenced the neuraminidase (NA) and hemagglutinin (HA) influenza A (H1N1) 2009 genes from ten HIV-positive patients involved in an epidemiologically defined outbreak in the Clinical Microbiology and Infectious Diseases (CMID) Department. Sequences were aligned to search for specific genetic features of the involv…
In-Depth Characterization and Functional Analysis of Clonal Variants in a Mycobacterium tuberculosis Strain Prone to Microevolution
The role of clonal complexity has gradually been accepted in infection by Mycobacterium tuberculosis (MTB), although analyses of this issue are limited. We performed an in-depth study of a case of recurrent MTB infection by integrating genotyping, whole genome sequencing, analysis of gene expression and infectivity in in vitro and in vivo models. Four different clonal variants were identified from independent intrapatient evolutionary branches. One of the single-nucleotide polymorphisms in the variants mapped in mce3R, which encodes a repressor of an operon involved in virulence, and affected expression of the operon. Competitive in vivo and in vitro co-infection assays revealed higher infe…
Fast and low-cost decentralized surveillance of transmission of tuberculosis based on strain-specific PCRs tailored from whole genome sequencing data: a pilot study
Molecular epidemiology has transformed our knowledge of how tuberculosis (TB) is transmitted. Whole genome sequencing (WGS) has reached unprecedented levels of accuracy. However, it has increased technical requirements and costs, and analysis of data delays results. Our objective was to find a way to reconcile speed and ease of implementation with the high resolution of WGS. The targeted regional allele-specific oligonucleotide PCR (TRAP) assay presented here is based on allele-specific PCR targeting strain-specific single nucleotide polymorphisms, identified from WGS, and makes it possible to track actively transmitted Mycobacterium tuberculosis strains. A TRAP assay was optimized to track…
