    The purpose of this research was to examine the psychometric properties of a Spanish translation of the Flow State Scale (FSS; Jackson & Marsh, 1996). This instrument is used to assess the Flow State in participants of physical activity, although it can be adapted to other contexts (such as work, educational contexts, etc.). This construct can be considered the optimal psychological state to carry out an activity, being closely related to motivation and personal enjoyment (Csikszentmihalyi, 1997). A sample of 2036 athletes was recruited from diverse sports activities. The results revealed satisfactory validity and internal consistency of the instrument, obtaining a factor model made up of a main factor and nine subscales. The correlations between motivational orientations and the flow state are highlighted. The Spanish translation of this instrument is found to be acceptable, with similar psychometric properties as the original scale, although future research in other contexts is needed to support these outcomes.El objetivo de esta investigación fue analizar las propiedades psicométricas de una versión adaptada al castellano de la Flow State Scale (FSS; Jackson y Marsh, 1996), instrumento utilizado para valorar el estado de fluidez en practicantes de actividad física, aunque adaptable a otros contextos (trabajo, educación…). Dicho constructo puede ser considerado como el estado psicológico óptimo para realizar una actividad, estando muy relacionado con la motivación y el disfrute personal (Csikszentmihalyi, 1997). Se desarrolló un estudio con 2036 participantes en diferentes actividades deportivas. Los resultados han demostrado que el instrumento posee una validez y consistencia interna aceptables, hallándose un modelo factorial compuesto por un factor principal y nueve factores secundarios. Asimismo, destacan las correlaciones entre las dos orientaciones motivacionales y el estado de fluidez. Se concluye que la adaptación al castellano del instrumento para valorar el estado de fluidez es aceptable, encontrándose propiedades psicométricas similares a las obtenidas en la escala original, aunque se necesitan nuevos trabajos en otros contextos que apoyen estos resultados

    Mixed Valvular Disease Following Transcatheter Aortic Valve Replacement: Quantification and Systematic Differentiation Using Clinical Measurements and Image-Based Patient‐Specific In Silico Modeling

    Background: Mixed valvular disease (MVD), mitral regurgitation (MR) from pre‐existing disease in conjunction with paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR), is one of the most important stimuli for left ventricle (LV) dysfunction, associated with cardiac mortality. Despite the prevalence of MVD, the quantitative understanding of the interplay between pre‐existing MVD, PVL, LV, and post‐TAVR recovery is meager. Methods and Results: We quantified the effects of MVD on valvular‐ventricular hemodynamics using an image‐based patient‐specific computational framework in 72 MVD patients. Doppler pressure was reduced by TAVR (mean, 77%; N=72; P<0.05), but it was not always accompanied by improvements in LV workload. TAVR had no effect on LV workload in 22 patients, and LV workload post‐TAVR significantly rose in 32 other patients. TAVR reduced LV workload in only 18 patients (25%). PVL significantly alters LV flow and increases shear stress on transcatheter aortic valve leaflets. It interacts with mitral inflow and elevates shear stresses on mitral valve and is one of the main contributors in worsening of MR post‐TAVR. MR worsened in 32 patients post‐TAVR and did not improve in 18 other patients. Conclusions: PVL limits the benefit of TAVR by increasing LV load and worsening of MR and heart failure. Post‐TAVR, most MVD patients (75% of N=72; P<0.05) showed no improvements or even worsening of LV workload, whereas the majority of patients with PVL, but without that pre‐existing MR condition (60% of N=48; P<0.05), showed improvements in LV workload. MR and its exacerbation by PVL may hinder the success of TAVR

    Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

    This study analyzes, from the social-cognitive point of view of the achievement goals perspective, the relationship between the motivational climate, goals orientations, and the behavioral patters of healthy lifestyles (i.e., practicing sports as extra-curricular activity, as well as the consumption of alcohol, tobacco and other drugs) of 500 physical education students between the age of 14 and 18 from Cáceres. For this purpose, The Health Behaviour School Children (HBSC), Perception of Success Questionnaire (POSQ) and Learning and Performance Orientations in Physical Education Classes Questionnaire (LAPOPEQ) was applied. Results show internal consistency and descriptive statistics. To analyze the relationship among the variables the Structural Equation Modeling (SEM) was employed too.Este estudo analisa, desde a perspectiva sócio-cognitiva das metas de sucesso, as relações entre os climas motivacionais, as orientações de meta e variáveis pertencentes aos estilos de vida saudáveis (como a realização da prática extra-escolar, o consumo de álcool, tabaco e outras drogas) de 500 estudantes de Educação Física de 14 a 18 anos da província de Cáceres. Para isto, foram aplicados os questionários de Estilos de Vida Saudáveis, Questionário de Percepção de Êxito e Questionário de Orientação à Aprendizagem e ao Rendimento nass aulas de E.F.
