Free time and its adequate use through recreation constitute a problem that has been given great attention in recent years by some institutions and authors from different parts of the world, which acquires greater significance when it is approached in the context of educational centers, due to its evident relation with the integral formation and quality of life of these schoolchildren. Within the educational centers, the schools of the sports education and training system deserve special attention, where the demands become more complex when academic education is harmoniously combined with sports practice and training. That is why the objective of this article focuses on assessing the importance of the use of Recreation in an educational and creative free time, from the context of the Basic Sports Formation, in terms of the integral formation of student-athletes. Starting from the analysis of published works related to the subject, the article makes an assessment in the context of the reality of student-athletes in these educational-sports centers. The need to deepen in the study of this population, their particularities and needs to provide them with an adequate use of their free time through varied recreational activities that contribute to their recreational satisfaction, integral formation and improvement of their quality of life is glimpsed.

Impact of an E-Learning Histology Course on the Satisfaction and Performance of Medical, Nursing and Midwifery Students / Impacto de un Curso E-Learning de Histología en la Satisfacción y Desempeño de Estudiantes de Medicina, Enfermería y Obstetricia

SUMMARY: The importance and relevance of e-learning courses in medicine and health sciences has increased significantly in the last decade. Despite this, there are few published teaching experiences of e-learning histology courses in the literature worldwide. The histology course we designed was structured on the Moodle platform as a learning management system, and the content was proposed in a synchronous (zoom) and asynchronous (recordings) format. We also included the use of free virtual microscopy tools. This study aimed to investigate the impact of an e-learning histology course on the satisfaction and performance of medical, nursing and midwifery students. The sample included 424 Chilean medical, nursing, and midwifery students from two cohorts. A Likert-type survey was administered at the end of the course. We performed exploratory analysis and ordinary least squares regression. In this study, we present a positive experience of an e-learning histology course. Exploratory factor analysis revealed three main factors related to "e- learning satisfaction", "in-person class activities", and "course design and teaching quality". We also found that there was a positive and significant relationship between students' perceptions of the adaptation of the traditional (face-to-face) histology course into an e-learning format and their academic performance. Our study shows that e-learning histology courses that integrate lectures and practical sessions can be a valuable teaching method for learning histology. Curriculum developers and teachers need to consider the limitations and advantages of this type of teaching and incorporate these three factors into the design and assessment of e-learning histology courses.

La importancia y relevancia de los cursos e-learning en medicina y ciencias de la salud ha aumentado significativamente en la última década. A pesar de ello, existen pocas experiencias docentes publicadas de cursos de histología e-learning en la literatura a nivel mundial. El curso de histología que diseñamos se estructuró en la plataforma Moodle, y los contenidos se propusieron en formato síncrono (zoom) y asíncrono (grabaciones). También incluimos el uso de herramientas gratuitas de microscopía virtual. Este estudio tuvo como objetivo investigar el impacto de un curso de histología e-learning en la satisfacción y el rendimiento de los estudiantes de medicina, enfermería y obstetricia. La muestra incluyó 424 estudiantes chilenos de medicina, enfermería y obstetricia de dos cohortes. Se aplicó una encuesta tipo Likert al final del curso. Se realizó un análisis exploratorio y una regresión por mínimos cuadrados ordinarios. En este estudio, presentamos una experiencia positiva de un curso de e-learning de histología. El análisis factorial exploratorio reveló tres factores principales relacionados con la "satisfacción sobre el aprendizaje e-learning", "clases presenciales versus clases virtuales" y el "diseño del curso y la calidad de la enseñanza". También encontramos que existía una relación positiva y significativa entre las percepciones de los estudiantes sobre la adaptación del curso de histología tradicional (presencial) a un formato e-learning y su rendimiento académico. Nuestro estudio muestra que los cursos de histología e-learning que integran clases teóricas y sesiones prácticas pueden ser una valiosa herramienta de enseñanza. Los responsables de la elaboración de planes de estudios y los profesores de histología deben tener en cuenta las limitaciones y ventajas de este tipo de enseñanza y sugerimos incorporar estos tres factores al diseño y la evaluación de los cursos de histología en línea.

Abstract Introduction: Upper-body muscular endurance (UBME) and aerobic capacity (AC) are essential components of physical fitness. Low levels of these components are related to cardiovascular disease. Purpose: To assess the association between UBME and AC levels in college students of physical culture. Methodology: Analytical cross-sectional study carried out in 192 students (169 men, 23 women; median age 20 years). Every participant of the study signed written consent. UMBE was the dependent variable assessed by the push-up test, and AC was the main independent variable assessed using the 20 m shuttle run test. To analyze differences by sex, and academic semester, Fischer exact, Student's T, and U Mann-Whitney tests were applied. Descriptive, as well as bivariate and multivariate analysis, were realized using logistic regression models. Results: 82.29 % of participants had healthy levels of UBME. Respecting the academic semester, students had a higher probability of having healthy levels of UBME as semesters increased (OR: 1.23, 95 % CI: 1.06 to 1.44, p = 0.007). Concerning AC, 58.33 % of participants registered healthy levels. After adjusting by sex, age, socioeconomic level, and academic semester, maximum oxygen consumption (VO2max), was associated with healthy levels of UBME (OR: 1.157, CI 95 %: 1.O71 - 1.249, p=<0.001). Conclusions: Students had a higher probability of presenting healthy levels of UBME as semesters of study increased, and those with a higheVO2max were more likely to have healthy levels of UBME.

The Impact of Various Factors on the Difficulties in Learning and Teaching Strategies for Histology / El Impacto de Diversos Factores en las Dificultades en el Aprendizaje y las Estrategias de Enseñanza de Histología

SUMMARY: Histology is considered one of the most important but challenging topics in health sciences. Deficiencies in teaching and general histology directly affect the student's understanding, performance and promote dynamism and integration while covering the primary curriculum. The goal of the current study was to assess and provide a better experience of difficulties in learning histology, examine some standard teaching strategies, and determine how to implement suitable changes to improve the curriculum from students' perspectives. The study comprised of a self-administered questionnaire that included descriptive questions. Data was collected based on the survey conducted via 100 students studying histology. Data was analyzed further qualitatively and quantitatively to elaborate on the difficulties in this area. Many of them strongly agreed that the lack of essential comprehension regarding using light and electron microscopes resulted in challenges with comprehending and identifying tissue samples for image identification due to inadequate anatomical knowledge. Moreover, according to students, some difficulties understood the topic, perception of new terminologies, and insufficient teaching strategies to grasp students' interests. They also agreed that improvement was needed in terms of the modes of teaching employed by histology teachers; they felt that modern education techniques based on practical tasks should be incorporated to stimulate student interest and make understanding histological concepts easier. The Institution should modify the teaching system to allocate more time to relevant subjects to make this subject matter more interesting. This survey-based study evaluated that students faced some challenges while studying the current curriculum of histology. From the student's perspective, it is identified that some changes are needed to improve the course curriculum and way of teaching to make it more understandable.

La histología se considera uno de los temas más importantes pero desafiantes de las ciencias de la salud. Las deficiencias en la enseñanza y en la histología general afectan directamente la comprensión, el desempeño del estudiante y promueven el dinamismo y la integración al abarcar el currículo primario. El objetivo del estudio actual fue evaluar y proporcionar una mejor experiencia de las dificultades en el aprendizaje de histología, examinar algunas estrategias de enseñanza estándar y determinar cómo implementar cambios adecuados para mejorar el plan de estudios desde la perspectiva de los estudiantes. El estudio constaba de un cuestionario auto administrado que incluía preguntas descriptivas. Los datos se recopilaron a partir de una encuesta realizada a 100 estudiantes de histología. Los datos se analizaron más a fondo de forma cualitativa y cuantitativa para profundizar en las dificultades en esta área. Muchos de ellos estuvieron totalmente de acuerdo en que la falta de comprensión esencial sobre el uso de microscopios ópticos y electrónicos resultó en desafíos para comprender e identificar muestras de tejido para la identificación de imágenes debido a un conocimiento anatómico inadecuado. Además, según los estudiantes, algunas dificultades en la comprensión del tema, percepción de nuevas terminologías y estrategias de enseñanza insuficientes para captar los intereses de los estudiantes. También coincidieron en que era necesario mejorar los métodos de enseñanza empleados por los profesores de histología; sintieron que deberían incorporarse técnicas educativas modernas basadas en tareas prácticas para estimular el interés de los estudiantes y facilitar la comprensión de los conceptos histológicos. La Institución debería modificar el sistema de enseñanza para asignar más tiempo a materias relevantes para hacer esta materia más interesante. Este estudio basado en encuestas evaluó que los estudiantes enfrentaron algunos desafíos mientras estudiaban el plan de estudios actual de histología. Desde la perspectiva del estudiante, se identifica que se necesitan algunos cambios para mejorar el plan de estudios del curso y la forma de enseñar para hacerlo más comprensible.

Escape Room como Herramienta Didáctica en la Enseñanza de la Histología / Escape Room as a Didactic Tool in Histology Teaching

En el marco de un proceso de aprendizaje activo, se investigó el rendimiento académico a corto y a largo plazo de los estudiantes en dos sesiones prácticas de la asignatura de Histología a las que se incorporó un escape room. También se evaluó su impacto en la motivación y la retención del conocimiento. Los estudiantes fueron clasificados en un grupo control, que siguió una metodología de enseñanza tradicional, y un grupo experimental, que participó en la actividad del escape room. Los resultados revelaron mejoras significativas en las calificaciones posteriores a la intervención en el grupo experimental. El estudio también evaluó la percepción estudiantil de la experiencia del escape room que demostró valoraciones muy satisfactorias.

SUMMARY: In the context of an active learning process, this study investigated the short-term and long-term academic performance of students in two practical sessions of the Histology course, which included an escape room activity. The impact of this approach on motivation and knowledge retention was also assessed. Students were divided into a control group, which followed a traditional teaching methodology, and an experimental group, which participated in the escape room activity. The results revealed significant improvements in post-intervention grades in the experimental group. Additionally, the study assessed students' perceptions of the escape room experience, which showed highly satisfactory evaluations.

Acute effects of air pollution on pulmonary function and exhaled nitric oxide in children in Shanghai / 上海预防医学

ObjectiveTo investigate the acute effects of compound air pollution on children’s respiratory function. MethodsUsing panel group study design， 223 students in five classes of grade 4 from two primary schools （a， b） in Xuhui and Hongkou districts of Shanghai were randomly selected to measure pulmonary function and exhaled nitric oxide （FeNO）. The first three tests were carried out from May to June in 2020， and the fourth test was carried out from September to December in 2021. At the same time， the daily and hourly mean values of PM2.5， PM10， SO2， NO2， O3 and CO was collected from the nearby air quality monitoring points of the two schools during the same period ， as well as meteorological monitoring data （temperature， humidity， wind speed and atmospheric pressure）. The linear mixed effect model was used to analyze the effects of air pollution on pulmonary function and respiratory inflammation in the summer. ResultsThe results of single pollutant model showed that PM2.5， PM10， SO2 and NO2 were positively correlated with FeNO， and the effect was reflected in lag0， lag1 and lag3 （P<0.05）. PM2.5， PM10 and NO2 were negatively correlated with the changes of lung function FEF25%， FEF50%， FEF75%， FeF25%-75%， PEF， FVC， FEV1 and FEV1/FVC， and the effect was reflected in lag0 to lag3 days （P<0.05）. The results of the dual pollutant model showed that the concentration changes of SO2 and NO2 were significantly correlated with the decrease of FEV1 when combined with O3 or PM2.5 （P<0.01）， and the concentration changes of PM2.5 was significantly correlated with the increase of FeNO when O3， SO2 and NO2 were combined respectively （P<0.01）. The effects of the dual pollutant model were greater than the effect of PM2.5 single pollutant model. ConclusionThe health effects of different air pollutants on children’s respiratory tract function indexes in summer are different. The combined effects of two pollutants on the lung function of children increased to different degrees. Although air pollution is light in summer， it still has an impact on children’s respiratory tract function index and inflammation index， and the combined effect of dual pollutants is more significant than that of single pollutant.
