Benefits of Online Sources of Information in the Tourism Sector: The Key Role of Motivation to Co-Create
(MDPI, 2021-08) García Haro, María Ángeles; Martínez Ruiz, María Pilar; Martínez Cañas, Ricardo; Ruiz Palomino, Pablo
Online sources of information are a matter of special interest in tourism research. In particular, they are key elements in the formation of destination image. The purpose of this paper is to examine the relationship between online sources of information and destination image and to analyze the mediating role of motivation to co-create in that relationship. A research model was developed, and hypotheses were tested on data collected from 394 usable responses about the World Heritage city of Cuenca (Spain). The results show that online commercial sources have a direct positive impact on the conative, affective and cognitive dimensions of the tourist image, in this order. Additionally, this study supports the view that motivation to co-create mediates the relationship between online information sources and destination image. Finally, motivation to co-create was also found to have a positive and direct impact, in this order, on conative, cognitive and affective image. The main value of our research is that it underlines the essential influence of motivation to co-create in the relationship between online information sources and destination image. This study also provides a critical review of the existing literature by positing a conceptual theoretical framework that links three types of online sources of information (social media sources, online commercial sources and online non-commercial sources) and destination image.

Comparative effect of physical exercise versus statins on improving arterial stiffness in patients with high cardiometabolic risk: a network meta-analysis
(Public Library Science, 2021) Cavero Redondo, Iván; Deeks, Jonathan J.; Álvarez Bueno, Celia; Jolly, Kate; Saz Lara, Alicia del; Price, Malcolm; Pascual Morena, Carlos; Martínez Vizcaíno, Vicente José Anastasio
Background
The comparative analysis of the effect of several doses of statins against different intensities of physical exercise on arterial stiffness (a measure of cardiovascular risk) could shed light for clinicians on which method is most effective in preventing cardiovascular disease (CVD) and be used to inform shared decision-making between doctors and patients. This study was aimed at analyzing the effect, in high cardiometabolic risk patients, of different statins doses and exercise intensities on arterial stiffness (a measure of cardiovascular risk) by integrating all available direct and indirect evidence in network meta-analyses.
Methods and findings
We systematically searched MEDLINE, Embase, SPORTDiscus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science databases from their inception to February 28, 2020; for unpublished trials, we also searched ClinicalTrials.gov. We searched for studies concerning the effect of statins or physical exercise on arterial stiffness, measured by pulse wave velocity (PWV). For methodological quality assessment, Cochrane Collaboration’s tool for assessing risk of bias (RoB2) was used. A network geometry graph was used to assess the strength of the evidence. Comparative evaluation of the interventions effect was performed by conducting a standard pairwise meta-analysis and a network meta-analysis (NMA) for direct and indirect comparisons between interventions and control/nonintervention. A total of 22 studies were included in the analyses (18 randomized controlled trials (RCTs) and 4 nonrandomized experimental studies), including 1,307 patients with high cardiometabolic risk from Asia (3 studies), Oceania (2 studies), Europe (10 studies), North America (5 studies), and South America (2 studies). The overall risk of bias assessed with RoB2 was high in all included studies. For standard pairwise meta-analysis and NMA, high-intensity exercise versus control (mean difference (MD) -0.56; 95% CI: -1.01, -0.11; p = 0.015 and -0.62; 95% CI: -1.20, -0.04; p = 0.038, respectively) and moderate statin dose versus control (MD -0.80, 95% CI: -1.59, -0.01; p = 0.048 and -0.73, 95% CI: -1.30, -0.15; p = 0.014, respectively) showed significant MDs. When nonrandomized experimental studies were excluded, the effect on high-intensity exercise versus control and moderate statin dose versus was slightly modified. The main limitation of this study was that the magnitude of the effect of the exercise interventions could be underestimated due to regression toward the mean bias because the baseline cardiometabolic risk profile of patients in the physical exercise intervention trials was healthier than those in the statins ones; consequently, more modest improvements in physical exercise interventions compared to statins interventions can be expected. Additionally, we might consider as limitations the small study sizes, the heterogeneous patient groups, the focus on a proxy endpoint (PWV), and the high risk of bias.
Conclusions
In this NMA, we found that although many patients could benefit from statins for reducing CVD risk, our results support that, considering the beneficial effects of high-intensity exercise on arterial stiffness, it would be worthwhile to refocus our attention on this type of exercise as an effective tool for the prevention of CVD.

Pensamiento computacional para todos. Adaptación de instrumentos de evaluación de percepciones y actitudes para la etapa de Educación Primaria
(Dykinson, 2024) Jiménez Toledo, Alicia; Olmo Muñoz, Javier del; Tirado Olivares, Sergio; González-Calero Somoza, José Antonio; Cózar Gutiérrez, Ramón
El pensamiento computacional (PC) se ha consolidado como una habilidad esencial en la era digital actual, no sólo para aquellos que se dedican a disciplinas tecnológicas, sino también como una competencia transversal crucial en una amplia gama de campos. La integración del PC en la educación desde una edad temprana es fundamental para fomentar en los alumnos habilidades esenciales de resolución de problemas, capacidad analítica, pensamiento lógico y creatividad (Bers et al., 2022). Esta exposición temprana prepara a los alumnos para desenvolverse y contribuir eficazmente en un mundo cada vez más dominado por la tecnología y la informática.

Exercise versus fixed-dose combination therapy for cardiovascular risk factors control and atherosclerotic disease prevention: a network meta-analysis protocol
(BMJ Publishing Group, 2020) Pozuelo Carrascosa, Diana Patricia; Cavero Redondo, Iván; Fernández Rodríguez, Rubén; Pascual Morena, Carlos; Sequí Domínguez, Irene; Martínez Vizcaíno, Vicente José Anastasio
INTRODUCTION: Despite the consistent evidence of the benefits of physical activity on preventing atherosclerotic cardiovascular diseases (ASCVD) and some cardiovascular risk factors, such as hypertension and dyslipidaemia, the prescription of drugs remains the most widely used approach to prevent ASCVD in clinical settings. The purpose of this study protocol is to provide a meta-synthesis methodology for comparing the effect of fixed-dose combination therapy and physical exercise on controlling cardiovascular risk factors and preventing ASCVD. METHODS AND ANALYSIS: This protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols and the recommendations of the Cochrane Collaboration Handbook. We plan to conduct a computerised search in Medline, Web of Science, Embase, Cochrane Database of Systematic Reviews and SPORTDiscus from inception to May 2020 for studies testing the effectiveness of physical exercise or fixed-dose combination drug therapy in preventing ASCVD, all-cause and cardiovascular mortality and controlling some cardiovascular risk factors (hypertension and dyslipidaemia). Since performing network meta-analyses (NMA) is a statistical approach that allows direct and indirect comparisons of interventions, where sufficient studies are included, we plan to perform the following NMA comparing the effect of fixed-dose combination therapy and physical exercise interventions on (1) improving lipid profile, (2) reducing blood pressure, (3) preventing cardiovascular events and all-cause and cardiovascular mortality and (4) improving compliance with the therapeutic strategy and reducing adverse events. ETHICS AND DISSEMINATION: Ethical approval will not be needed because data included in the NMA will be extracted from published trials that meet accepted ethical standards. The results will be published in academic peer-reviewed journals, and the evidence gathered by this project could be included in the preventive cardiovascular disease guidelines. PROSPERO REGISTRATION NUMBER: CRD42019122794.

Association Between Eating Habits and Perceived School Performance: A Cross-Sectional Study Among 46,455 Adolescents From 42 Countries
(Frontiers, 2022) López Gil, José Francisco; Eumann Mesas, Arthur; Álvarez Bueno, Celia; Pascual Morena, Carlos; Saz Lara, Alicia del; Cavero Redondo, Iván
PURPOSE: This study analyzed the association between selected self-reported eating habits and perceived school performance in adolescents by gender. METHODS: A cross-sectional analysis was conducted with data from a large representative sample of adolescents from 42 different countries. Participants answered questions about their weekly frequency of fruit, vegetable, sweets, and soft drink consumption, as well as the frequency of breakfast consumption and family meals. The adolescents subjectively rated their school performance compared to that of their classmates. Logistic regression models were adjusted for region, age, body mass index (z-score), socioeconomic status, physical activity, recreational screen time, and sleep difficulties. RESULTS: Among the 46,455 (53.5% female, mean age of 13.7 ± 1.6 years) adolescents studied, 20.6% of males and 25.5% of females reported high perceived school performance. In the results of the fully adjusted analyses, the higher the frequency of all healthy eating habits studied, the higher the perceived school performance in both males and females. Specifically, both males and females reporting a higher frequency of fruit and vegetable consumption, a lower frequency of sweets and soft drink consumption, more frequent breakfast consumption, and more frequent family meals (breakfast and dinner) were more likely to perceive their school performance as higher compared to their classmates. In addition, having breakfast regularly on weekends and the frequency of family dinner were associated with better school performance in both males and females. CONCLUSIONS: In summary, this study provide cross-sectional evidence on the association between healthy eating habits and perceived school performance. Considering that school performance is an indicator of healthy development in adolescence, our findings reinforce and extend the evidence on the importance of healthy eating at this stage of life.
