Psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) for caregivers of children with gastrostomy tu…
2013
BACKGROUND: To analyse the psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) in parents/caregivers of children with home enteral nutrition (HEN) by gastrostomy tube (GT). METHODS: Eighty-six caregivers (mothers) of paediatric patients with HEN by GT were recruited. Patients suffered from neurological disease (61.6%) and other chronic diseases. The SAGA-8 scale, a structured questionnaire to explore satisfaction with HEN by GT, and the Caregiver Burden Inventory (Zarit) were completed. The discriminating power of each of the SAGA-8 items, internal consistency and external validity were evaluated. An exploratory factor analysis and Kaiser-M…
Impact of lens material on objective refraction in eyes with trifocal diffractive intraocular lenses
2021
Purpose: Compare subjective (Rx) and objective (ObjRx) refractions outcomes with two autorefractors models and an aberrometer in eyes implanted with a hydrophobic trifocal IOL (FineVision POD F GF, Physiol, Liége, Belgium) and a hydrophilic one (FineVision POD F, Physiol, Liége, Belgium). Methods: Prospective comparative cohort study, with 100 subjects randomly assigned to either the POD F group (n = 50) or the POD F-GF group (n = 50). Postoperative eye examinations at 1-month visit included seven result sets, one for each assessment method: Rx, AR (automated refraction measured with the autorefractor KR8800), WF-P (Zernike-coefficients-based objective refraction, photopic pupil size), WF-M…
Differential prognostic impact of type 2 diabetes mellitus in women and men with heart failure with preserved ejection fraction
2020
Introduction and objectives Type 2 diabetes mellitus (DM2) is a common comorbidity in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Previous studies have shown that diabetic women are at higher risk of developing HF than men. However, the long-term prognosis of diabetic HFpEF patients by sex has not been extensively explored. In this study, we aimed to evaluate the differential impact of DM2 on all-cause mortality in men vs women with HFpEF after admission for acute HF. Methods We prospectively included 1019 consecutive HFpEF patients discharged after admission for acute HF in a single tertiary referral hospital. Multivariate Cox regression analysis was used to …
ANÁLISIS DEL COMPORTAMIENTO DE QUEJA DEL CONSUMIDOR: UNA INVESTIGACIÓN EXPLORATORIA EN EL CONTEXTO DE LOS RESTAURANTES /
2008
RESUMENEl objetivo de este trabajo es analizar la contribución que tiene una serie de determinantes en el comportamiento de queja con el fin de identificar la combinación que mejor explica las respuestas de queja, a terceras partes y privadas. Utilizando el contexto de los restaurantes y la metodología basada en modelos de regresión múltiple (método secuencial de estimación paso a paso), los resultados más relevantes indican que la probabilidad de éxito de la queja es la variable que mayor influencia tiene sobre las respuestas de queja, mientras que es el nivel de insatisfacción en el caso de las respuestas privadas.ABSTRACTThe aim of this paper is to analyze the contribution that a set of …
Predicting future intentions of basketball spectators using SEM and fsQCA
2016
This study analyzes relationships among service quality, perceived value, satisfaction, emotions, and future intentions of spectators of a professional basketball competition using a sample of 429 basketball spectators of a premier division in Spain. The results from structural equation modeling support the hypotheses, except for the effect of emotions and match result on future intentions. The results from fuzzy-set qualitative comparative analysis (fsQCA) with the same data set show that none of the variables are necessary conditions for positive future intentions of spectators. However, seven combinations of these variables are sufficient conditions for explaining positive future intenti…
Spectator emotions: Effects on quality, satisfaction, value, and future intentions
2015
There is a great interest from the academic and professional fields to know the performance of sports enterprises from the point of view of the user and the sport spectators. This study analyzes relationships between service quality, perceived value, satisfaction, future intentions, and emotions of spectators of a professional basketball competition. A self-report survey yields data for 493 spectators. After confirming reliability and validity of the data collection measures, an application of structural equation modeling to empirical data tests the model. Results show that (1) service quality predicts spectators' satisfaction and perceived value, and that perceived value and satisfaction a…
Internal employability as a strategy for key employee retention
2014
Las economías alrededor del mundo, en especial en países delsur de Europa, están sufriendo los paralizantes efectos de la extremadamentecompleja crisis económica y financiera. Este estudio examina el impactode ciertas políticas de recursos humanos enfocadas a incrementarla empleabilidad interna como un medio para retener a los empleados valiososy para promover la flexibilidad laboral dentro de la empresa, asícomo para incrementar las actitudes positivas hacia la ciudadanía organizacional.Se proponen la satisfacción y el compromiso como variables queintermedian la relación entre la empleabilidad interna percibida y la intenciónde abandonar la empresa y sobre el desarrollo de comportamientode…
Structural and Vibrational Properties of Corundum-type In2O3 Nanocrystals under Compression
2017
[EN] This work reports the structural and vibrational properties of nanocrystals of corundum-type In2O3 (rh-In2O3) at high pressures by using angle-dispersive x-ray diffraction and Raman scattering measurements up to 30 GPa. The equation of state and the pressure dependence of the Raman-active modes of the corundum phase in nanocrystals are in good agreement with previous studies on bulk material and theoretical simulations on bulk rh-In2O3. Nanocrystalline rh-In2O3 showed stability under compression at least up to 20 GPa, unlike bulk rh-In2O3 which gradually transforms to the orthorhombic Pbca (Rh2O3-III-type) structure above 12 14 GPa. The different stability range found in nanocrystallin…
Magnetic molecularly imprinted polymer for the simultaneous selective extraction of phenoxy acid herbicides from environmental water samples
2022
[EN] A selective magnetic molecularly imprinted polymer (MMIP) was synthetized with 4-chloro-2-methylphenoxyacetic acid as template and 4-vinylpiridine as monomer in presence of vinylized magnetite nanoparticles. Scanning electron microscopy, nitrogen adsorption-desorption isotherms, Fourier transform infrared spectrometry and vibrating sample magnetometry were applied to characterize the resulting material. The synthesized MMIP was applied as sorbent in magnetic molecularly imprinted solid-phase extraction (MMISPE) for selective extraction of a mixture of the five herbicides 4-chloro-2-methylphenoxyacetic acid (MCPA), 4-(4-chloro-2-methylphenoxy)butyric acid (MCPB), mecoprop (MCPP), fenoxa…
Evaluación de competencias en redacción científica tras dos modalidades diferentes de cursos de formación: protocolo del Estudio SCRIU-B
2021
La redacción de artículos científicos es una de las competencias necesarias y solicitadas por los profesionales de la salud. Existen distintos formatos de cursos para adquirirlas, pero no siempre se evalúa objetivamente su impacto. Con un diseño experimental abierto y no aleatorizado, el estudio SCRIU-B pretende evaluar la adquisición de competencias en redacción científica tras la realización de cursos de formación específicos (presenciales y en línea), así como la satisfacción de los participantes. Se incluye un grupo control con alumnado de otras actividades formativas no relacionadas con la escritura científica. Mediante distintos cuestionarios de evaluación de conocimientos, actitudes …
