Adaptación al castellano y validación del cuestionario sobre práctica basada en la evidencia en fisioterapeutas / Spanish adaptation and validation of evidence-based practice questionnaire in physiotherapists

Introducción Una práctica basada en la evidencia científica (PBE) se define como un proceso cuyo objetivo es la selección de los mejores argumentos científicos para la resolución de los problemas que se plantean en la práctica clínica. Sin embargo, la falta de instrumentos válidos en castellano y de estudios representa una dificultad para establecer la situación actual de esta corriente científica dentro de la Fisioterapia en España. El objetivo de este estudio ha sido la adaptación a la lengua castellana y el análisis de la fiabilidad del cuestionario sobre PBE en Fisioterapia. Material y métodos Se llevó a cabo la traducción inversa del cuestionario sobre PBE para, posteriormente, realizar un estudio prospectivo de test-retest para el análisis de las propiedades psicométricas de la versión castellana de cuestionario. Se utilizó una muestra de 41 fisioterapeutas clínicos titulados sin formación previa en PBE ni en metodología avanzada de la investigación. Resultados Los valores para el ICC se sitúan en el rango 0,333-0,885, obteniéndose una reproducibilidad de moderada-buena en todos los ítems (ICC >0,400). El análisis de alfa de Cronbach se sitúa en valores alfa>0,700, logrando una buena consistencia interna global. El análisis de la fiabilidad intraobservador mediante el índice de kappa se sitúa entre 0,396-0,688 para ítems dicotómicos. Conclusiones Se ha obtenido la suficiente validez para hacer uso como instrumento de recogida de datos para la investigación, a través del análisis de las propiedades psicométricas, de la versión adaptada y traducida al castellano del cuestionario sobre PBE diseñado por Jette et al (AU)

Introduction Evidence-based practice (EBP) is defined as a process aimed at selecting the best scientific arguments for solving problems within the clinical practice. However, the lack of validated instruments and scientific publications in Spanish is a challenge when it comes to establishing what is the current status of this scientific approach within Physiotherapy in Spain. The aim of this study was to analyze and assess the reliability of EBP in physiotherapy using a questionnaire adapted to Spanish. Material and methods A back-translation of the questionnaire on EBP was performed in order to conduct a prospective test-retest study for the analysis of the psychometric properties of the Spanish version of the questionnaire. A sample of 41 licensed clinical physiotherapists participated in the study. None of them had prior training in EBP or advanced research methodology. Results Values for the ICC were in the range of 0.333-0.885, resulting in a moderate to good reproducibility in all items (ICC> 0.400). The Cronbach's alpha analysis was set at alpha> 0.700, obtaining a good overall internal consistency. The analysis of intra-observer reliability using kappa index was 0.396-0.688 for dichotomous items. Conclusions Through the analysis of the psychometric properties of the adapted and translated Spanish version of the questionnaire on EBP designed by Jette et al., this study has obtained sufficient validity for its use as a tool for collecting data for research (AU)

Cauterization of meso-ovarian vessels, a new model of intrauterine growth restriction in rats.

Intrauterine growth restriction (IUGR) remains an important cause of perinatal morbidity and mortality. Both IUGR and low birth weight have been identified as risk factors for increased incidence of cardiovascular disease, dyslipemia, and other diseases in the adulthood. Several animal models have been developed to study the underlying mechanisms of IUGR and its later consequences, with utero-placental ischemia by uterine artery ligation (UAL) being the most frequently used in rats. The relevance of this model lies in the fact that it induces altered placental perfusion, the main cause of IUGR in humans in Western countries. However, there is also controversy over the grade and homogeneity of IUGR obtained. In this study, we propose a new animal model of IUGR related to placental ischemia through the cauterization of meso-ovarian vessels. We aimed to test the feasibility of meso-ovarian vessel cauterization (CMO), and to compare it with uterine artery ligation (UAL). The CMO group had similar incidence of perinatal mortality, percentage of IUGR, and evolution of body weight during early extrauterine life to the UAL group, indicating that both methods are similarly efficient for inducing IUGR. Moreover, both of them affect the ratio of fetal to placental weight, and the weight of vital organs, supporting the hypothesis of a fetal compensatory response or "brain- and heart-sparing effect". Both operative models suffer approximately 50% perinatal mortality, implying that they are both more efficient in the production of IUGR when C-section is performed. On the other hand, CMO was significantly faster to perform than UAL and seemed to produce a more uniform ischemia throughout the uterus than the UAL method, resulting in a more homogeneous group of IUGR pups.
