Actividad física durante una jornada escolar con y sin clase de educación física y salud en estudiantes chilenos. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-18. Los altos índices de obesidad y el aumento del tiempo sedentario en los escolares tienen consecuencias directas en la prevalencia de enfermedades no transmisibles en edad adulta. El entorno escolar es una oportunidad para combatir estos factores de riesgo y la importancia de la clase de educación física es relevante. El objetivo del estudio fue comparar el nivel de actividad física, gasto energético y tiempo sedentario entre una jornada con y sin clases de educación física en niños y niñas de primer ciclo básico. Es un estudio no experimental, analítico transversal con una muestra intencionada de 46 escolares de primer ciclo básico. Se midió índice de masa corporal (IMC), actividad física, gasto energético y tiempo sedentario con acelerometría en jornada escolar con y sin clase de educación física. Se utilizó la prueba no paramétrica de Wilcoxon para determinar diferencias entre las jornadas escolares (p < .05). Los resultados muestran que, durante la jornada con clases de educación física, los escolares presentaron un nivel de actividad física moderada (3.03 MET) y, en la jornada sin clases de educación física, un nivel ligero (2.32 MET). Los estudiantes en la jornada escolar con educación física tuvieron mayores niveles de actividad física moderada (Z = -4.430; p < .0001), vigorosa (Z = -5.403; p < .0001), muy vigorosa (Z = -3.940; p < .0001) y disminuyeron el tiempo sedentario (Z = -4.149; p < .0001) con respecto a la jornada sin clase de educación física. Se concluye que aun cuando durante la jornada con educación física, los escolares tienen mayor actividad física, mayor gasto energético y menor tiempo sedentario, este rendimiento resulta insuficiente de acuerdo con las recomendaciones internacionales para la salud.

Sepúlveda Martin, S., Martínez González, L., Cigarroa, I., & Zapata Lamana, R.E. (2022). Physical activity indicators during a school day with and without physical education class and health among chilean students. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-18. High obesity rates and the increase in sedentary time among schoolchildren have direct consequences on the prevalence of non-communicable diseases in adulthood. The school environment is an opportunity to deal with these risk factors, and the importance of physical education classes is critical. The object of this study was to compare the level of physical activity, energy expenditure and sedentary time between a day with physical education class and one without, among first- to third-grade children. This is a non-experimental, analytic, cross-cutting study with a deliberate sample of 46 schoolchildren. Body Mass Index (BMI), physical activity, energy expenditure and sedentary time were measured with accelerometry on school days with and without physical education class. Wilcoxon's non-parametric test was used to determine differences between school days (p < .05). The results show that schoolchildren had a moderate level of physical activity (3.03 MET) during a day with physical education class, and a light level (2.32 MET) during a school day without physical education class. Students in a school day with physical education class had higher levels of moderate ( Z = -4.430; p < .0001), energetic (Z = -5.403; p < .0001) and highly energetic (Z = -3.940; p < .0001) physical activity, and their sedentary time was lower ( Z = -4.149; p < .0001) as compared to a day without physical education time. The conclusion is that, even though schoolchildren have higher physical activity, higher energy expenditure and lower sedentary time during a day with physical education class, this performance proves insufficient as compared to international recommendations for health.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-18. As altas taxas de obesidade e o aumento do tempo sedentário em estudantes têm consequências diretas sobre a prevalência de doenças não transmissíveis na idade adulta. O ambiente escolar é uma oportunidade de combater esses fatores de risco e a importância da aula de educação física é relevante. O objetivo do estudo foi comparar o nível de atividade física, gasto energético e tempo sedentário entre um dia letivo com e sem aulas de educação física em crianças do primeiro ciclo da educação fundamental. Trata-se de um estudo não experimental, analítico transversal com amostra intencional de 46 estudantes do primeiro ciclo da educação fundamental. O índice de massa corporal (IMC), a atividade física, o gasto energético e o tempo sedentário foram medidos com a acelerometria no dia letivo com e sem aula de educação física. O teste não paramétrico de Wilcoxon foi utilizado para determinar diferenças entre os dias letivos (p < 0,05). Os resultados mostram que, durante o dia com aulas de educação física, os escolares apresentaram nível moderado de atividade física (3,03 MET) e, no dia sem aulas de educação física, nível leve (2,32 MET). Os alunos no dia letivo com educação física apresentaram níveis mais elevados de atividade física moderada (Z = -4,430; p < 0,0001), vigorosa (Z = -5,403; p < 0,0001), muito vigorosa (Z = -3,940; p < 0,0001) e diminuição do tempo sedentário (Z = -4,149; p < 0,0001) em relação ao dia letivo sem aula de educação física. Conclui-se que, embora durante o dia letivo com educação física os escolares tenham maior atividade física, maior gasto energético e menos tempo sedentário, esse desempenho é insuficiente de acordo com as recomendações internacionais para a saúde.

[Increased screen hours are associated with low school performance]. / Aumento de horas de pantalla se asocia con un bajo rendimiento escolar.

OBJECTIVE: To analyze whether screen time is related to lower academic performance in second-cycle students and to determine differences by sex. SUBJECTS AND METHOD: Analytical, retrospective, and cross-sectional research. 733 students from the 5th to 8th year of public schools participating in the study "school health and performance survey in the Biobío province 2018" were recruited. The use of the screen was self-reported through daily hours in front of the TV, video games, and the internet. School performance was measured with the report card of reading, math, physical education, and the grade point average and through behaviors related to cognition in the school context. To determine the relationship between screen time and school performance, the Pearson's correlation coefficient was determined, and to measure the influence of sex and screen hours on the grades, a two-way ANOVA was performed. RESULTS: The students spend 6.1 ± 5.3 hours in front of a screen daily. Boys spend more time playing video games and girls surfing the internet. Both boys and girls who spend more hours in front of a screen, mainly playing video games and surfing the internet, presented lower grades in mathematics, reading, physical education, grade point average, and had less memory, were slower in solving mathematical problems and had more difficulties in maintaining attention in class or solving complex tasks. CONCLUSION: Screen use is negatively associated with academic performan ce, as well as behaviors related to cognition in students of both sexes.

Tratamiento endovascular de la estenosis de los senos venosos intracraneales en la hipertensión intracraneal: descripción de tres casos y discusión de la bibliografía / Endovascular treatment of intracranial venous sinus stenosis in intracranial hypertension: three case reports and a discussion of the literature

INTRODUCCIÓN: La hipertensión intracraneal idiopática es una entidad con una incidencia anual aproximada de 1,2 por cada 100.000 habitantes. Afecta en mayor proporción a mujeres obesas y en edad fértil. La cefalea es el síntoma más característico, seguido de las alteraciones visuales. En los últimos años, se ha incrementado el diagnóstico de la estenosis de los senos durales en los casos de hipertensión intracraneal resistentes al tratamiento convencional. Por ello, se encuentra en auge el desarrollo de la terapia endovascular como opción terapéutica en pacientes seleccionados. Casos clínicos. Se presentan tres casos de hipertensión intracraneal secundaria a estenosis de los senos durales, diagnosticados y tratados en nuestro hospital. A pesar de la instauración del adecuado tratamiento diurético y de la realización de procedimientos invasivos de derivación del líquido cefalorraquídeo, persistían la clínica neurológica y el déficit visual. Tras comprobar que cumplían los requisitos descritos en la bibliografía, se sometieron a la implantación de stent intracraneal (stenting), con resultado satisfactorio en todos ellos, logrando la desaparición de la cefalea y la recuperación de la agudeza visual. CONCLUSIÓN: El stenting de la estenosis de los senos durales como causa de hipertensión intracraneal es una técnica cada vez más utilizada que ha presentado resultados favorables. Es necesaria la realización de estudios para conocer su impacto a largo plazo

INTRODUCTION: Idiopathic intracranial hypertension is an entity with an incidence of approximately 1.2: 100,000 inhabitants/year. It affects in a greater proportion obese women and women of childbearing age. Headache is the most characteristic symptom, followed by visual disturbances. In recent years, the diagnosis of dural sinus stenosis has increased in cases of intracranial hypertension resistant to conventional treatment. For this reason, the development of endovascular therapy as a therapeutic option in selected patients is booming. Case reports. We present three cases of intracranial hypertension secondary to dural sinus stenosis, diagnosed and treated in our hospital. Despite the establishment of adequate diuretic treatment and the performance of invasive procedures to bypass the cerebrospinal fluid, they persisted with neurological symptoms and visual deficits. After verifying that they fulfilled the requirements described in the literature, they underwent intracranial stenting, with satisfactory results in all of them, achieving the disappearance of the headache and recovery of visual acuity. CONCLUSION: Stenting of dural sinus stenosis as a cause of intracranial hypertension is an increasingly used technique, which has presented favorable results. Studies are necessary to know its long-term impact
