Motivos de participação dos estudantes universitários em atividades físico-desportivas

El objetivo del presente artículo es contribuir al análisis de los motivos de participación de los estudiantes universitarios en la práctica físico-deportiva. También se pretende establecer diferencias por género y conocer dónde practican deporte los universitarios alicantinos. Para ello, se llevó a cabo una investigación no experimental descriptiva en la que participaron 400 alumnos seleccionados por muestreo no probabilístico por cuotas entre todas las facultades de la Universidad de Alicante, a los que se les aplicó el cuestionario MIAFD (Pavón, 2004). Los resultados indican que la mayoría de la población universitaria practicaba actividades físico-deportivas (58.7%). Los motivos más habituales fueron: para estar en forma (85.9%), para liberar energía (80.8%) y para mejorar la salud (78.3%). En cambio, el principal motivo para no practicar actividad física era la falta de tiempo debido a los estudios. Los hombres afirman en mayor medida que las mujeres practicar actividades físico-deportivas para competir y superarse.The purpose of this paper is to identify the university students’ motives to participate in physical and sports activities. It also aims to determine gender differences and to know where they practice these activities. A non-experimental descriptive study was conducted for this purpose. Four hundred students were selected using a non-probability sampling by quota procedure among all the colleges of the University of Alicante, to whom the MIAFD questionnaire (Pavón, 2004) was administered. Results indicate that most of the university population practiced physical and sport activities (58.7%). The most common reasons for participating in sports were: for fitness (85.9%), to release energy (80.8%) and to improve health (78.3%). On the other hand, the lack of time was the main reason for not practicing physical and sports activities. Competition and self-improvement are motives more frequently adduced by male students than female participants.O objetivo do presente artigo é detectar os motivos dos estudantes universitários em atividades físico-desportivas.

Influencia de la adición de escorias de aluminio en las propiedades de productos de arcilla cocida

El presente trabajo plantea la reutilización directa de escorias de aluminio procedentes de la metalurgia secundaria mediante. La escoria con un contenido variable del 10-20% de aluminio metálico y oxido de aluminio es triturada hasta obtener una fracción inferior a las 600micras. Las mezclas con arcilla en contenidos del 10 y 20% de escoria se realizaron en un molino de bolas (145rpm/30min). Mediante compactación en matriz a 100 MPa se alcanzaron densidades de 2.2-2.3 g/cm3. Los materiales de arcilla cocida a 980 presentaron densidades finales de 1.95-2.1 g/cm3. La distribución de la escoria es muy uniforme en el material cocido, mejorando su densidad y disminuyendo la absorción de agua. La resistencia a flexión se mejora con la adición de escorias, si bien no hay diferencias importantes entre las composiciones empleadas. Una mayor temperatura de cocción (1080?) mejora la densidad final y disminuye la absorción de agua. La realización de un tratamiento termoquímico previo a los polvos de escorias, permite mejorar su la resistencia a flexión de las mezclas con 10% y 20% de escoria y reducir la variación dimensional y la absorción de agua tras cocción a 950

Epidemiology of Chagas Disease in Non-Endemic European Countries

Chagas disease results from infection by the protozoan Trypanosoma cruzi and was presviously described as an endemic disease focused in populations living in poor rural areas of Latin American countries. Currently, migrant populations and some modes of transmission such as blood and organ donation or vertical transmission from infected mothers to their children have caused the spread of this disease beyond its natural geographical boundaries. In Europe, Spain, with over half of these migrants, is undoubtedly the most important recipient, followed by Italy, France and United Kingdom. However, in non-endemic countries there is no universal screening systems and also physicians are often poorly trained in recognizing this disease. So far, few countries are aware of the emergence of this disease and only few European countries have established changes in their health system to address this disease. The National European Health authorities should take part to this model-of-care, adapting in this new epidemiological scenario with screening this pathology in blood donors, organ donations or vertically from mother to child at birth. These mechanisms are the main forms of human infestation in nonendemic countries and are, therefore, the major targets for reduction of spread

Characteristics and Outcomes of Elderly Patients Refused to ICU

Background. There are few data regarding the process of deciding which elderly patients are refused to ICU admission, their characteristics, and outcome. Methods. Prospective longitudinal observational cohort study. We included all consecutive patients older than 75 years, who were evaluated for admission to but were refused to treatment in ICU, during 18 months, with 12-month followup. We collected demographic data, ICU admission/refusal reasons, previous functional and cognitive status, comorbidity, severity of illness, and hospital and 12-month mortality. Results. 338 elderly patients were evaluated for ICU admission and 88 were refused to ICU (26%). Patients refused because they were “too ill to benefit” had more comorbidity and worse functional and mental situation than those admitted to ICU; there were no differences in illness severity. Hospital mortality rate of the whole study cohort was 36.3%, higher in patients “too ill to benefit” (55.6% versus 35.8%, P<0.01), which also have higher 1-year mortality (73.7% versus 42.5%, P<0.01). High comorbidity, low functional status, unavailable ICU beds, and age were associated with refusal decision on multivariate analysis. Conclusions. Prior functional status and comorbidity, not only the age or severity of illness, can help us more to make the right decision of admitting or refusing to ICU patients older than 75 years

Predictors of atrial tachyarrhythmias in adults with congenital heart disease

Background: Atrial tachyarrhythmias (ATs) represent the major late complications of congenital heart diseases (CHDs) following surgery. Little is known about the association between echocardiographic parameters and AT. Aims: This study aimed to investigate a potential correlation among clinical, echocardiographic, and electrocardiographic parameters and AT as well as to analyze outcomes in adults with CHD and AT. Methods: A retrospective case‑control study was performed in adults with CHD. We included 71 patients with AT and 71 control individuals matched by sex, age, and the type of CHD without AT, all from the same institute. Medical records, electrocardiograms, and echocardiograms were reviewed. Adverse cardiovascular events were recorded and defined as cardiovascular mortality, admission for heart failure, or stroke. The univariate and multivariate logistic regression analysis of possible risk factors and the Kaplan–Meier analysis of adverse cardiovascular events were performed. Results: Subpulmonary ventricular systolic pressure≥40 mm Hg (hazard ratio [HR], 6.8; 95% CI, 2.4–18; P &lt; 0.001), right atrial dilatation≥21 cm2 (HR, 3.1; 95% CI, 1.2–7.6; P = 0.01), and significant tricuspid regurgitation (HR, 4; 95% CI, 1.3–10; P = 0.02) were identified as the main risk factors for AT. Patients with AT had worse outcomes, more frequently developed adverse cardiovascular events (86% vs 14%; P &lt; 0.01), and exhibited a 58% event‑free survival rate compared with 98% of the patients without AT after 8 years of follow‑up (log rank, 6.6; P = 0.01). Conclusions: Among patients with CHD, the main risk factors for AT include right atrial dilatation, high subpulmonary ventricular systolic pressure, and significant tricuspid regurgitation. The presence of AT may increase the risk of adverse cardiac events

Natural History and Clinical Predictors of Atrial Tachycardia in Adults With Congenital Heart Disease

BACKGROUND: Atrial tachycardias (ATs) are a significant source of morbidity in adults with congenital heart disease (CHD). This study evaluates the incidence and clinical predictors of AT in a cohort of patients with CHD.METHODS AND RESULTS: We included 3311 adults (median age at entry 22.6 years, 50.6% males) with CHD (49% simple, 39% moderate, and 12% complex) prospectively followed up in a tertiary center for 37 607 person-years. Predictors of AT were identified by multivariable Cox regression analysis accounting for left truncation. An external validation was performed in a contemporary cohort of 1432 patients. Overall, 153 (4.6%) patients presented AT. AT burden was highest in complex CHD, such as single ventricle (22.8%) and D-transposition of the great arteries (22.1%). Hazard rates of AT across lifetime, age at presentation, and the time lapse between surgery and the first AT episode varied among the most common CHD. Independent risk factors for developing AT were univentricular physiology, previous intracardiac repair, systemic right ventricle, pulmonary hypertension, pulmonary regurgitation, pulmonary atrioventricular valve regurgitation, pulmonary and systemic ventricular dysfunction. At the age of 40 years, AT-free survival in patients with 0, 1, 2, and >= 3 risk factors was 100%, 94%, 76%, and 50%, respectively. These findings were confirmed in the validation cohort.CONCLUSIONS: Natural history of AT differed among the most common forms of CHD. Simple clinical parameters, easily obtained by noninvasive means, were independent predictors of AT in adults with CHD. Although risk was negligible in patients without any of these factors, their addition progressively increased AT burden

El arte infantil sin fronteras

El proyecto pretende enfocar de forma diferente las formas de expresión artística infantil, sin fronteras temporales, espaciales ni metodológicas. El proyecto forma parte de la experiencia del grupo Enterarte Reencuentros, ciclos vitales aquí y allí; la vida y sus momentos aquí y allá; instantes distantes; hitos; mitos y ritos para la vida. El proyecto se centra en el acercamiento a otras culturas, dentro del tema hitos, mitos y ritos para la vida, y trata sobre los mitos que explican el origen de la vida a través de la expresión artística, usando como eje los cuatro elementos. Los objetivos son utilizar el museo como recurso cultural; intercambiar experiencias y formación con otros centros con un objetivo común; conocer la cultura americana, apreciando y aceptando las diferencias con la propia; contribuir a una manifestación cultural colectiva en un medio abierto; experimentar con recursos plásticos de las distintas culturas; y crear obras con algunos de los lenguajes artísticos. La metodología sigue los principios de significación, globalización, acción-experimentación, interacción niño-niño y niño-adulto, organización espacio-temporal, adecuación y diversidad de materiales, respeto a los diferentes ritmos personales, y coordinación docente y con el resto de la comunidad educativa. Se utiliza el personaje de Titi-caca como elemento motivador. Las actividades son las visitas de Titi-caca, con su presentación, y la presentación del viento, de la Navidad, y del elemento Tierra; guiñol; la representación de los cuatro elementos, la Semana del Cuento; la creación de un cuento viajero por los padres; salidas al Retiro y al Museo de América; Fiesta de Carnaval; y actividades relacionadas con el viento, tierra, fuego, y agua. La evaluación se realiza a través de registros de observación, diarios, anecdotarios, diálogo con las familias, grabación de vídeos, fotografías, y registros de actividades. Se elaboran materiales, algunos incluidos como anexos, como la historia de Titi-caca, poesías de la representación de los cuatro elementos, la canción de Titi-caca, y fotografías de las actividades..Madrid (Comunidad Autónoma).
