    .Objective Asthma is a chronic disease that may affect physical fitness, although its primary effects on exercise capacity, muscle strength, functionality and lifestyle, in children and adolescents, are still poorly understood. This study aimed to evaluate the differences in cardiorespiratory fitness, muscle strength, lifestyle, lung function, and functionality between asthmatics with exercise symptoms and healthy children. In addition, we have analyzed the association between clinical history and the presence of asthma. Study Design Cross-sectional study including 71 patients with a diagnosis of asthma and 71 healthy children and adolescents (7–17 years of age). Anthropometric data, clinical history, disease control, lifestyle (KIDMED and physical activity questionnaires), lung function (spirometry), exercise-induced bronchoconstriction test, aerobic fitness (cardiopulmonary exercise test), muscle strength and functionality (timed up and go; timed up and down stairs) were evaluated. Results Seventy-one patients with asthma (mean age 11.5 ± 2.7) and 71 healthy subjects (mean age 10.7 ± 2.5) were included. All asthmatic children had mild to moderate and stable asthma. EIB occurred in 56.3% of asthmatic children. Lung function was significantly (p < .05) lower in the asthmatic group when compared to healthy peers, as well as the cardiorespiratory fitness, muscle strength, lifestyle and functionality. Moreover, asthmatic children were more likely to have atopic dermatitis, allergic reactions, food allergies, and a family history of asthma when compared to healthy children. Conclusions Children with mild-to-moderate asthma presenting exercise symptoms show a reduction in cardiorespiratory fitness, muscle strength, lung function, functionality, and lifestyle when compared to healthy peers. The study provides data for pediatricians to support exercise practice aiming to improve prognosis and quality of life in asthmatic children.S

    La transmisión del SARS-CoV-2 generalmente ocurre por gotitas respiratorias de diferente tamaño. Los síntomas de presentación suelen incluir fiebre, tos, astenia, mialgia o disnea. La mayoría de las personas infectadas son asintomáticas o tienen una enfermedad leve, pero una minoría desarrolla insuficiencia respiratoria progresiva que requiere hospitalización y soporte respiratorio. El tratamiento es fundamentalmente de soporte, sin embargo, en pacientes hospitalizados, algunos agentes antivirales directos (administrados durante los primeros días de la infección) y el tratamiento inmunomodulador con esteroides y bloqueadores de citocinas (en el periodo de hiperinflamación), pueden mejorar el pronóstico. No obstante, se necesitan nuevas moléculas antivirales frente a SARS-CoV-2, con buena tolerancia y que se puedan administrar por vía oral, para evitar la progresión de la enfermedad, prevenir el contagio en pacientes de riesgo y cortar la cadena de transmisión. La duración exacta de la inmunidad después de la infección natural o la vacunación aún espera un estudio de seguimiento a largo plazo. Después de una COVID aguda, un número significativo de pacientes desarrollan diversos síntomas persistentes que, en la mayoría de personas, mejoran espontáneamente a lo largo de las semanas o meses siguientes. La pandemia de COVID-19 ha provocado millones de infecciones en todo el mundo, con morbi-mortalidad significativa, y generado una tensión extrema en los sistemas sanitarios y económicos. La buena noticia es la aparición de vacunas muy eficaces que están ayudando a controlar la enfermedad en países desarrollados; de su implementación masiva durante los próximos meses, incluyendo a los países con menos recursos, va a depender el control adecuado de esta pandemia

Sample Challenges at Moodle (126), Appendix H. Participants’ questionnaire results (128).La gamificación es un término que suele denotar el uso de componentes del juego en situaciones no relacionadas con el juego en sí para crear experiencias de aprendizaje agradables, divertidas y motivadoras para los estudiantes (Werbach y Hunter, 2012). Por lo tanto, el análisis de los factores básicos de los juegos se convierte en algo esencial a la hora de definir y utilizar la gamificación como estrategia de mediación del inglés como lengua extranjera para fortalecer rasgos específicos de pronunciación en los estudiantes de pregrado de la UPTC Sogamoso. El procedimiento de estudio se basa en la investigación acción mediante la implementación de la estrategia de gamificación para la mediación en la pronunciación del inglés, orientada a treinta estudiantes de diferentes programas de ingeniería, administración y tecnología con niveles heterogéneos de dominio del inglés. Las actividades se centran principalmente en la producción de sonidos, el ritmo, el acento y la entonación, los rasgos de pronunciación segmental y suprasegmental. Los resultados arrojaron una evidente mejora en las características segméntales y suprasegmentales de la percepción en la pronunciación de los participantes así como la contribución del objetivo de los juegos a la instrucción fonética y fonológica, la sensación en el juego a la motivación para mejorar la pronunciación, el reto establecido en los juegos a la actitud positiva de los participantes, y la sociabilidad a la exposición practica de la pronunciación inglesa.Gamification is a relatively new term that often denotes the use of game components in situations unrelated to the game itself to create enjoyable, fun, and motivating learning experiences for students (Werbach and Hunter, 2012). Therefore, analyzing the games' basic factors becomes essential when defining and using gamification as a strategy for English as Foreign Language mediation to strengthen specific pronunciation features in UPTC Sogamoso undergraduate students. The study procedure is based on action research by implementing the gamification strategy for mediation in English pronunciation, oriented to thirty students from different engineering, management, and technology programs at heterogeneous levels of English proficiency. The activities mainly focus on sound production, rhythm, stress, and intonation, segmental and suprasegmental pronunciation features. The results showed an evident improvement in the segmental and suprasegmental features of the participants' pronunciation perception as well as the contribution of game goals to phonetics and phonological instruction, the game sensation to the motivation for pronunciation improvement, the game challenge to the participants' positive attitude, and the sociality to the English pronunciation exposure practice

Error de mesura i límits d'acord de les puntuacions calculats a partir de la desviació típica de la diferència de les mitjanes van indicar una probabilitat molt baixa de ser diferents entre ells. L'efecte sòl/sostre va indicar que aquest efecte no es va produir L'anàlisi de regressió de les mitjanes i diferències de les puntuacions totals de tots els models va indicar un augment significatiu de les diferències en les puntuacions a mesura que el valor mitjà d'aquestes va augmentar. Les diferències entre tots els models van ser significatives. Conclusions: Es presenta un qüestionari per a mesurar els coneixements sobre la postura corporal i la cura de l'esquena en activitats de la vida diària en adolescents validat. Es determina que les mateixes dades, es poden analitzar utilitzant diferents models, proporcionant cadascun d#aquests informació diferent

    Building body identities - exploring the world of female bodybuilders

    This thesis explores how female bodybuilders seek to develop and maintain a viable sense of self despite being stigmatized by the gendered foundations of what Erving Goffman (1983) refers to as the 'interaction order'; the unavoidable presentational context in which identities are forged during the course of social life. Placed in the context of an overview of the historical treatment of women's bodies, and a concern with the development of bodybuilding as a specific form of body modification, the research draws upon a unique two year ethnographic study based in the South of England, complemented by interviews with twenty-six female bodybuilders, all of whom live in the U.K. By mapping these extraordinary women's lives, the research illuminates the pivotal spaces and essential lived experiences that make up the female bodybuilder. Whilst the women appear to be embarking on an 'empowering' radical body project for themselves, the consequences of their activity remains culturally ambivalent. This research exposes the 'Janus-faced' nature of female bodybuilding, exploring the ways in which the women negotiate, accommodate and resist pressures to engage in more orthodox and feminine activities and appearances

    The Professional Identity of Doctors who Provide Abortions: A Sociological Investigation

    Get PDF
    Abortion is a medicalised problem in England and Wales, where the law places doctors at the centre of legal provision and puts doctors in control of who has an abortion. However, the sex-selection abortion scandal of 2012 presented a very real threat to 'abortion doctors', when the medical profession's values and practices were questioned in the media, society and by Members of Parliament. Doctors found themselves at the centre of a series of claims that stated doctors were acting both illegally and unethically, driven by profit rather than patient needs. Yet, the perspectives of those doctors who provide abortions has been under-researched; this thesis aims to fill that gap by examining the beliefs and values of this group of doctors. Early chapters highlight the ambiguous position of the abortion provider in Britain, where doctors are seen as a collective group of professionals motivated by medical dominance and medical autonomy. They outline how this position is then questioned and contested, with doctors being presented as unethical. By studying abortion at the macro-, meso- and micro-levels, this thesis seeks to better understand the values of the 'abortion doctor', and how these levels shape the work and experiences of abortion providers in England and Wales. This thesis thus addresses the question: 'What do abortion doctors' accounts of their professional work suggest about the contemporary dynamics of the medicalisation of abortion in Britain?'. It investigates the research question using a qualitative methodological approach: face-to-face and telephone interviews were conducted with 47 doctors who provide abortions in England and Wales. The findings from this empirical study show how doctors' values are linked to how they view the 'normalisation of abortion'. At the macro-level doctors, openly resisted the medicalisation of abortion through the position ascribed to them by the legal framework, yet at the meso-level doctors construct an identity where normalising abortion is based on further medicalising services. Finally, at the micro-level, the ambiguous position of the abortion provider is further identified in terms of being both a proud provider and a stigmatised individual. This thesis shows that while the existing medicalisation literature has some utility, it has limited explanatory power when investigating the problem of abortion. The thesis thus provides some innovative insights into the relevance and value of medicalisation through a comprehensive study on doctors' values, beliefs and practices

    The need for robust critique of arts and health research: young people, art therapy and mental health

    Get PDF
    We describe work in progress to conduct a systematic review of research on effects of arts-based programs for mental health in young people. We are at the stage of searching for relevant studies through major databases and screening extant systematic reviews for additional research which meet our inclusion criteria. At this stage, however, concerns have arisen regarding both the quality of existing primary studies and of recently published systematic reviews in this area of arts and health. As a case in point, in this paper we focus on one research report on art therapy with adolescent girls and its inclusion in three systematic reviews. We demonstrate that the reviews fail to undertake a robust critique of the Bazargan and Pakdaman paper and that the paper and reviews are flawed. Drawing on recent criticisms of systematic reviewing, we consider the value of proceeding with our systematic review as initially planned.
