Abordaje y presentación del quiste aracnoideo de la cisterna cuadrigeminal en pediatría: una serie de casos
Authors: Ramírez Espinoza Alberto 
Published: November 2024

Los quistes aracnoideos de la cisterna cuadrigeminal (QACC) representan un grupo poco frecuente de lesiones del sistema nervioso central. El cuadro clínico depende de la extensión del quiste y de la severidad de la compresión. Se realizó una revisión retrospectiva de los casos con diagnóstico de QACC intervenidos quirúrgicamente en el Instituto Nacional de Salud del Niño San Borja en el periodo 2017-2024. Se recopilaron datos sociodemográficos y clínicos de los pacientes a partir de las historias clínicas. Durante el periodo de estudio, 10 pacientes diagnosticados con QACC fueron intervenidos quirúrgicamente. Cinco pacientes presentaron QACC tipo I y cinco tipo III. El 80 % de los casos recibió una neuroendoscopia con fenestración del quiste. El 70 % de pacientes requirió solo una cirugía. El 50 % de los pacientes quedaron libres de cualquier forma de derivación del líquido cefalorraquídeo. En nueve pacientes, se observó disminución del tamaño del quiste; mientras que en el caso restante, la resolución completa de la lesión luego de dos cirugías. En esta serie de casos, la aplicación de la neuroendoscopia con fenestración del quiste demostró una mejoría en el cuadro clínico de los QACC, así como una disminución del tamaño o resolución del quiste.

Gender policies in sports aim to promote the presence of women in management positions in sports organizations. In this context, from the data of three wide surveys conducted in Chile during the last decade, this article had two objectives: to compare the presence of women and men in boards of directions in different types of sports organizations; and to analyze differences in profiles between women and men in high-responsibility positions in each organization. The results showed a significant under-representation of women in management and leadership positions. The study found that Chilean sports organizations are vertically segregated, with a few having a balance between women and men, so despite the incorporation of women on boards of directors, there is still male predominance. The research highlights the need for measures for an effective application of gender policies in sports.
Las políticas de género en el deporte pretenden impulsar la presencia de mujeres en cargos directivos de organizaciones deportivas. En este contexto, a partir de los datos de tres amplias encuestas realizadas en Chile durante la última década, este artículo tenía dos objetivos: comparar la presencia de mujeres y hombres en los cargos directivos de diferentes tipos de organizaciones deportivas; y analizar las diferencias en el perfil de mujeres y hombres en los puestos de máxima responsabilidad en cada organización. Los resultados mostraron una significativa infrarrepresentación femenina en los cargos directivos y de liderazgo. El estudio constató que las organizaciones deportivas chilenas poseen una segregación vertical, siendo pocas las que cuentan con un equilibrio entre mujeres y hombres, de modo que a pesar de que se hayan incorporado mujeres en las juntas directivas, existe una predominancia masculina. La investigación releva la necesidad de medidas para la aplicación efectiva de políticas de género en el deporte.

The aim of this study was to examine whether a relationship exists between the motivational climate and adolescents' interest, effort, and progression in learning in Physical Education classes, considering both gender and physical activity level. The following questionnaires were applied: PMCSQ-2, IEPA, AYES, and PAQ-C to a sample of n=3169 Chilean adolescents. The results were studied through descriptive and correlational analyses showing that there are statistically significant correlations when students perceive that the teacher acts intentionally in their classes towards the task climate, they show greater interest, effort and progression in their learning, highlighting greater motivation in the group that has mild PA in both males and females. But when these variables are related to ego climate, they only correlate positively in men, and negatively in women. When the dispositional and contextual variables are correlated, there is greater interest, effort and progress in learning in the PE class in men. It is necessary for PE teachers to focus their classes on the homework climate, because this will promote greater interest, effort and progression in learning, and will encourage possible adherence to the acquisition of healthier lifestyles.
El objetivo de este estudio fue examinar si existe una relación entre el clima motivacional y el interés, esfuerzo y progreso en el aprendizaje de los adolescentes en las clases de Educación Física, considerando tanto el género como el nivel de actividad física. Aplicándose los cuestionarios: PMCSQ-2, IEPA, AYES, y PAQ-C a una muestra de n=3169 adolescentes chilenos. Los resultados se estudiaron mediante análisis descriptivos y correlacionales mostrando que existen correlaciones estadísticamente significativas cuando los estudiantes perciben que el profesor actúa intencionadamente en sus clases hacia el clima tarea presentan mayor interés, esfuerzo y progresión en su aprendizaje, destacando mayor motivación en el grupo que tiene AF leve tanto en hombres y mujeres. Pero cuando estas variables se relacionan con el clima ego, solo correlacionan positivamente en los hombres, contrariamente a las mujeres estas son negativas. Cuando se correlacionan las variables disposicionales y las contextuales en los hombres existe un mayor interés, esfuerzo y progresión por aprender en la clase de EF. Es necesario que el profesorado de EF centre sus clases en el clima tarea, porque así potenciará un mayor interés, esfuerzo y progresión en el aprendizaje, y fomentará una posible adherencia a la adquisición de estilos de vida más saludables.

The literature presents a variety of methods to improve acceleration speed, such as resisted sled sprint training. The aim of this study was to describe the behavior of time, speed, and speed loss when executing accelerations in 20 meters without load and with a resistance sled with loads equivalent to 8%, 12%, and 15% of body weight. It corresponded to a descriptive cross-sectional study. A repeated measures ANOVA analysis was performed for the four conditions: acceleration race without resistance; with 8% of body weight; 12% of body weight; and 15% of body weight in time in seconds to travel the first 10 meters; the 10 to 20 meter section; and the entire distance from 0 to 20 meters; speed in km/h to travel from 0 to 10 meters; from 10 to 20 meters; and from 0 to 20 meters; speed loss with different loads, contrasted with running without resistance; from 0 to 10 meters; from 10 to 20 meters; and from 0 to 20 meters. The sled training showed limited speed losses with very light resistances of 8%, while light resistances of 12% and 15% produced significant losses over the average speed, exceeding the threshold that affected the kinetics and kinematics of the acceleration race.

Maximum oxygen consumption VO2max has represented a fundamental reference when measuring cardiorespiratory fitness in different sports. The aim of this study was to present the results of ergometry tests with gas analysis in athletes who exceeded 70 ml/kg/min in VO2max, analyzing the correlations between VO2max and metabolic, cardiovascular, and respiratory parameters. The study was of a descriptive correlational type, and 27 male athletes participated. The r Pearson test was applied to determine the correlation between the variables. In the result analysis, correlations were determined: small between Age and VO2max (r = -0.238; p = 0.24); large between VO2max vs VO2VT1 (r = 0.741; p<0.001); VO2max vs VO2VT2 (r = 0.808; p<0.001); and VO2VT1 vs VO2VT2 (r = 0.783; p<0.001). Mean between VO2max and HR (r = 0.340; p = 0.09); large between absolute VO2max and VO2/HRmax (r = 0.840; p<0.001); small between VO2max and VE (r = 0.214; p = 0.30); small between VO2max and BR (-0.184; p = 0.37); small between VE and RR% (r = -0.281; p = 0.164). There were large correlations between VO2max and ventilatory thresholds, and there was also a large correlation between absolute VO2max and oxygen pulse, with small and non-existent correlations between VO2max and ventilatory parameters.

This study aimed to determine the influence of the outdoor education learning models and mental toughness on cardiorespiratory fitness (CRF) levels. A quasi-experimental method was used, employing a 2x2 factorial design. The 2x2 factorial design in this study involved two learning models: the TGT (Team Games Tournament) and STAD (Student Teams Achievement Division), along with two levels of mental toughness: high and low. The sample consisted of 80 students from Jakarta State University, enrolled in recreational sports courses. The subjects in this study were given the TGT and STAD learning models over a period of 9 weeks. The tests administered during the pretest measured cardiorespiratory fitness using the Bleep Test and mental toughness using a questionnaire. The results showed that both the TGT and STAD outdoor education models have a statistically significant impact on students' CRF levels (p<0.05). Additionally, an interaction effect was observed between the learning model and the level of mental toughness (p<0.05). Specifically, the TGT model showed a greater influence on CRF in students with high mental toughness (p<0.05), while the STAD model was more effective in students with low mental toughness (p<0.05). Both the outdoor education learning model and mental toughness influence the level of CRF, suggesting that outdoor education can enhance CRF, which may positively affect academic performance and mental health of students.

Melanin governs the complex interplay of genetics, environment, and evolution, manifesting in the diverse array of human skin tones. Produced by melanocytes in the basal layer of the epidermis, melanin exists in two forms: pheomelanin, yielding yellow and red hues, and eumelanin, yielding brown and black hues. This dynamic interaction of melanin subtypes gives rise to the rich tapestry of human skin colors. While melanin's primary function is to protect the skin from UV-induced molecular damage, dysregulation can lead to hyperpigmentation, which can have profound emotional and cosmetic implications. To address hyperpigmentation, various skin-lightening treatments have been developed. For melasma, treatments include hydroquinone, corticosteroids, and tretinoin, while novel approaches such as the tetrapeptide Pro-Lys-Glu-Lys (PKEK) are used for post-inflammatory hyperpigmentation. However, the desire for lighter skin is often driven by societal and cultural influences rather than medical necessity. Throughout history, many cultures have associated fair skin with beauty, femininity, and social status, perpetuating a preference for lighter skin tones. Safer alternatives to traditional skin-lightening treatments, such as sunscreen, offer a more sustainable approach. Sunscreen not only protects against UV-induced aging and cancer but also helps manage pigmentary disorders like melasma and post-inflammatory hyperpigmentation. While advancements in skin-lightening therapies provide hope for those dealing with hyperpigmentation, addressing the underlying cultural and societal pressures is crucial for promoting healthier and more inclusive beauty standards.

This research aims to increase interest in learning and critical thinking of class The background to this research is because students' low interest in learning, especially in learning mathematics. In the learning process, a student's interest in learning plays an important role in the teaching and learning process, because if students have low interest in learning, it will be difficult for them to receive knowledge from the teacher, so that learning outcomes will be less effective. This research uses the Classroom Action research method (PTK) which consists of two cycles. The techniques used for data collection are: planning, implementing actions, observing and evaluating and reflecting. Before that, initial observations were carried out in order to find out information or characteristics of students. The results of the research show that the PBL type cooperative learning model was applied to matrix material for class XI students at SMA Negeri 21 Surabaya. This can be seen from the increase in implementation results, observation and reflection. Students' learning activities experienced a significant increase in cycle two compared to cycle one. By learning using the PBL method, it is possible for students to more easily understand the material because it relates to problems around them and with discussions students can work together and help each other if they experience problems. Apart from that, this method can also help develop their critical thinking and communication skills.
