Descripción de los niveles de Burnout en diferentes colectivos profesionales
2008
El interés en la investigación del Burnout proviene del hecho de tratarse de un problema social que afecta a muchas personas. Los datos epidemiológicos sobre el síndrome hablan de un pro- blema de tal magnitud, que conlleva consecuencias personales y laborales negativas. Este hecho justifica por sí mismo que el desarrollo investigador haya crecido de manera considerable en es- tos últimos años. Si bien es cierto que existen diversos colectivos profesionales de riesgo de pa- decimiento del síndrome de Burnout, también lo es, que los niveles del mismo en sus diferentes dimensiones, suelen cambiar, e incluso la secuenciación en las mismas en la aparición del pro- blema, se puede ver alterada. …
Phosphodiesterase inhibition induces retinal degeneration, oxidative stress and inflammation in cone-enriched cultures of porcine retina.
2013
nherited retinal degenerations affecting both rod and cone photoreceptors constitute one of the causes 74 of incurable blindness in the developed world. Cyclic guanosine monophosphate (cGMP) is crucial in the 75 phototransduction and, mutations in genes related to its metabolism are responsible for different retinal 76 dystrophies. cGMP-degrading phosphodiesterase 6 (PDE6) mutations cause around 4e5% of the retinitis 77 pigmentosa, a rare form of retinal degeneration. The aim of this study was to evaluate whether phar- 78 macological PDE6 inhibition induced retinal degeneration in cone-enriched cultures of porcine retina 79 similar to that found in murine models. PDE6 inhibition was induced…
Comparing Job Stress, Burnout, Health and Traffic Crashes of Urban Bus and BRT Drivers
2017
Professional driving is a very demanding task. According to the recent scientific evidence, Bus drivers tend to report high levels of occupational stress, burnout and occupational traffic accidents. With the implementation of new transportation modes, some substantial benefits and adverse circumstances for public transport operators have been documented. BRT (Bus Rapid Transit) systems have been implemented in different cities worldwide as an efficient alternative to fulfill difficulties and limitations related to traditional Urban Bus systems. However, in order to compare the efficiency of different public transport modes, it is important to assess, in addition to objective indicators, the…
Measuring job stress in transportation workers: psychometric properties, convergent validity and reliability of the ERI and JCQ among professional dr…
2021
Abstract Background The accumulated evidence has shown how professional drivers are, in psychosocial terms, among the most vulnerable workforces, and how their crashes (some of them preceded by stressful working conditions) constitute both an occupational and public health concern. However, there is a clear lack of validated tools for measuring stress and other key hazardous issues affecting transport workers, and most of the existing ones, frequently generic, do not fully consider the specific features that properly describe the work environment of professional driving. This study assessed the psychometric properties, convergent validity and consistency of two measures used for researching…

Estudi dels patrons oscil·latoris de l’escorça prefrontal medial en la gestió de l’estrès
2016
Aquesta memòria recull el treball realitzat per Na Aina Luque i Garcia al Departament d’Anatomia i Embriologia Humana de la Facultat de Medicina de la Universitat de València sota la direcció del Dr. Vicent Teruel i Martí i la Dra. Joana Martínez i Ricós, entre els anys 2011 i 2016. El primer objectiu d’aquest treball ha estat caracteritzar el patró d’activitat neuronal oscil·latòria de l’escorça prefrontal medial en una situació d’estrès. Per a la qual cosa s’ha estudiat l’activitat poblacional d’aquesta àrea cortical després de portar a terme l’activació del nucli central de l’amígdala. A més, donat que la serotonina està implicada tant en la generació de la resposta d’estrès com en el se…
Predicció d'estratègies d'afrontament a partir de dimensions emocionals, en infants i adolescents
2019
espanolEl objetivo de la presente investigacion consiste en analizar la prediccion de estrategias de afrontamiento a partir de las dimensiones de inteligencia emocional, y los trastornos de la emocion de ansiedad y depresion. Participaron 147 estudiantes de Primaria y ESO −49% de hombres y 49% mujeres− con edades comprendidas entre 12 y 14 anos. Los instrumentos utilizados fueron: una escala para evaluar las estrategias de afrontamiento, un inventario emocional, un cuestionario educativo-clinico para evaluar ansiedad/ depresion; y un cuestionario para la autoevaluacion ansiedad estado/rasgo. Para la valoracion de los datos se realizaron distintos analisis de regresion simple y multiple. Los…
Estudi de la plasticitat estructural en malalties psiquiàtriques amb models animals
2021
El concepte científic de l’estrès s’associa a una resposta adaptativa front a un estímul ambiental o una demanda. Tot i això, si les pertorbacions al medi ambient són constants, es produeix un desgast a l’organisme que té efectes perjudicials en aquest. El cervell es pot considerar l’òrgan central de l’estrès, ja que en ell comença la principal resposta biològica. És conegut que esdeveniments estressants de curta duració poden potenciar les funcions neuronals i millorar el rendiment cognitiu. D’altra banda, llargs períodes d’estrès poden alterar més profundament la fisiologia de diverses regions del sistema nerviós i afectar al seu funcionament, produint dèficits cognitius i d’aprenentatge.…

Antioxidant Therapies and Oxidative Stress in Friedreich´s Ataxia: The Right Path or Just a Diversion?
2020
Friedreich's ataxia is the commonest autosomal recessive ataxia among population of European descent. Despite the huge advances performed in the last decades, a cure still remains elusive. One of the most studied hallmarks of the disease is the increased production of oxidative stress markers in patients and models. This feature has been the motivation to develop treatments that aim to counteract such boost of free radicals and to enhance the production of antioxidant defenses. In this work, we present and critically review those 'antioxidant' drugs that went beyond the disease's models and were approved for its application in clinical trials. The evaluation of these trials highlights some …
