Single-use plastics are expected to disappear, mainly due to the rise of stricter regulations to combat their impact on the environment. As an example, the recent European Directive on Single-Use-Plastics (SUP) will be implemented between 2021 and 2024 and will directly prohibit the use of some SUP. Baby diapers are one of the most used single-used products in our daily lives, and it is estimated that most of the ~4000 diapers that each baby uses in their life go to landfill. Such diapers usually contain superabsorbent polymers (SAP) that are based on acrylic acid-acrylamide mixtures with high water retention capacity, but they are neither bio-based nor biodegradable. In this work, we have developed bio-based superabsorbent aerogels made of cellulose nanofibers (CNF) and propose their potential use in baby diapers. TEMPO-oxidized CNF at different oxidation degrees were prepared and tested. The obtained CNF exhibited higher free swelling capacity (FSC) than the commercial fluff pulp (ranging from 117.62% to 245.21% higher) and also than the diaper absorbent, except for CNF-5 (ranging from 31.56% to 54.55%), even under compression. Overall, the present work shows a case study where CNF could have a potential application with market opportunities.

Este artículo presenta el proyecto desarrollado durante el año 2011 por las unidades y centros de formación de las universidades públicas catalanas. El proyecto se orienta a la mejora de la calidad del sistema de educación superior y de la actividad del profesorado universitario mediante planes de formación específicamente diseñados con esta finalidad, centrándose primeramente en la identificación de competencias docentes definidas por la comunidad académica. Partiendo del contexto de implementación del Espacio Europeo de Educación Superior se identifican aquellas competencias propias de la función docente, para que posteriormente puedan ser adquiridas, desarrolladas y evaluadas mediante la formación, identificando modelos, estrategias, instrumentos y recursos que lo permitan. El proceso de identificación de las competencias docentes del profesorado universitario se ha desarrollado partiendo de una revisión bibliográfica del estado del arte, para posteriormente ser modificada y validada por grupos de discusión conformados por expertos en competencias y formación docente. Los resultados de identificación de dichas competencias han sido finalmente refrendados mediante una encuesta respondida por una muestra representativa de la comunidad académica de las ocho universidades públicas catalanas. El objetivo fundamental del proyecto que aquí presentamos no es otro que el de contribuir a una formación de calidad del profesorado universitario, que permita la adquisición, desarrollo y evaluación de las competencias que, como docente, gran parte de la comunidad académica considera que debe poseer para el ejercicio de su labor profesional, definidas como: interpersonal, metodológica, comunicativa, de planificación y gestión de la docencia, de trabajo en equipo y de innovación.

Purpose: Tobacco is the second most commonly used drug by Spanish high school students and e-cigarette use has increased over the last three years among this population. Students who reported smoking tobacco and/or e-cigarette use often have friends and family that also consume these substances. The aims of the present study were to: determine the prevalence of tobacco and electronic cigarette consumption among young adolescents, the age of initiation and the intention to consume both of these substances in the future; study the relationships between their current tobacco and e-cigarette consumption status, intentions to consume these substances in the future and the consumption of these substances by family members living in their home and friend’s consumption status; investigate the relationship between their current tobacco and e-cigarette consumption status, friends’ consumption status and their intention to consume each substance in the future; analyse the relationship between current consumption status, intentions to consume in the future and perceived risk; identify the main predictors of intentions to use these substances in the future. Methods: A cross-sectional survey was conducted in 2017. The sample consisted of 468 school students in the first cycle of secondary education in Catalonia, Spain. The participants who were aged between 11 and 15 years old, with 49.4% being female. Results: A stepwise binary logistic regression showed that the best predictors of the intention to smoke tobacco in the future were: having tried tobacco, being a current consumer, having a family member smoking at home and having a low perceived risk of smoking. The best predictors of the intention to use electronic cigarettes in the future were: having tried tobacco, being a current consumer and having friends who smoke or use electronic cigarettes. Conclusion: Smoking prevention programs must consider the social network surrounding teenagers, particularly close friends and family. Intervention strategies for delaying the onset of tobacco or e-cigarette consumption are greatly needed.

Background: The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living. Aim: To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex. Methods: A prospective, longitudinal and observational design was used. Results: A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = −0.304; p < 0.001), functional limitation (β = −0.466; p < 0.001) and mental health (β = −0.565; p < 0.001) and quality of life. Conclusions: The chronification of low back pain complicates people’s biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

El aula inversa (AI) es un enfoque metodológico que invierte el modo de enseñanza tradicional poniendo el foco activo en el estudiante. Es una metodología dinámica en la que el profesor facilita el aprendizaje de los estudiantes proporcionando material adecuado para la preparación previa de las clases y acompañando en la profundización de los contenidos y resolución de situaciones o problemas relacionados con el tema de estudio dentro del aula. Por eso, está considerada como una metodología de innovación docente. El objetivo general del presente trabajo es analizar la evidencia científica sobre la efectividad del AI en el ámbito universitario. Siguiendo las recomendaciones PRISMA se realizó una revisión sistemática de la literatura publicada en las bases de datos Web of Science, Scopus y ERIC entre los años 2016 y 2022, se han analizado un total de 27 estudios experimentales o cuasiexperimentales que cumplieron los criterios de selección definidos. Se analizaron variables descriptivas, de diseño y la valoración de la eficacia, la valoración de los estudiantes y los condicionantes que inciden en la eficacia del AI. Los resultados muestran un mayor número de publicaciones en los continentes asiático y americano y en los ámbitos de ciencias y educación. El 87% de los artículos estudian el nivel de grado universitario y más del 81% utilizan grupo control en su diseño de estudio. La evidencia muestra la efectividad de la aplicación del AI en relación con los resultados académicos de los estudiantes en los distintos grados, así como en la adquisición de habilidades consideradas transversales en el ámbito universitario. La satisfacción de los estudiantes respecto a la metodología es buena y las mejoras en su efectividad se relacionan con aspectos que dependen de los mismos estudiantes, los profesores y la universidad.

Healthcare professionals (HCPs) are among those most affected by the COVID-19 health emergency, with many presenting symptoms of anxiety and depression. Research shows that one of the factors involved in mitigating the impact of stressful situations is the use of cognitive emotional regulation mechanisms. The aims of this study were (a) to describe the functional and dysfunctional cognitive emotional regulation mechanisms (FRMs and DRMs) by gender, (b) to screen the main group of healthcare professionals who are candidates to receive psychological assistance based on FRMs and DRMs, and (c) to determine the HCP profile of candidates for psychological assistance. A cross-sectional descriptive study was conducted. Data were obtained from an adhoc questionnaire—the Cognitive Emotional Regulation Questionnaire (CERQ-18), the Generalized Anxiety Disorder scale (GAD-7), and the nine-item Patient Health Questionnaire (PHQ-9). The representative sample comprised 1452 HCPs. The results revealed significant differences between men and women in the use of DRMs. Women showed a higher use of catastrophizing (≤0.001) and rumination (0.008). The screening procedure detected that 7.5% (109 cases) of the HCPs were candidates to receive psychological support. According to the results of this study, age group (30–39 years old), professional activity (being a nurse or nursing assistant), and having psychological symptoms of anxiety and depression are variables that independently increase the probability of requiring psychological assistance. The gender variable was not found to be an independent factor when it comes to receiving psychological support. In conclusion, it is necessary to consider the influence of cognitive emotional regulation strategies employed by HCPs in the screening of candidates for psychological assistance and design effective interventions to reverse the emotional distress caused by COVID-19.
