    Drawing on writings by recent post-modernist thinkers and semioticians, this paper focuses on a combination of hermeneutic and semiotic viewpoints and applies them to defining the nature of interpretation in an educational setting (e.g., text interpretation), the interpreter, and the essence of the act of comprehension and interpretation. The main…

  3. Sobre el estado evolutivo de β Pictoris

    NASA Astrophysics Data System (ADS)

    Brunini, A.; Benvenuto, O. G.

    Desde el descubrimiento de fuertes excesos infrarrojos en β Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. β Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a βPic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en β Pic indica edades avanzadas para β Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para β Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

    2014-01-01

    We investigated the effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) concentrations. Eighteen male participants completed two different exercise sessions with intensities of 25% and 65% maximal aerobic capacity (VO2max). In addition to the energy expenditure during exercise sessions being measured, blood samples were collected before exercise, and immediately, at 24 h, and at 48 h post-exercise to analyse sOB-R, leptin and insulin levels. At 24 h post-exercise, sOB-R and leptin concentrations at the 65% VO2max were significantly different from those at the 25% VO2max. Leptin levels at 48 h post-exercise were also significantly lower for the 65% VO2max than for the 25% VO2max (P < 0.01). In the 65% VO2max session, the energy expenditure during exercise was significantly associated with leptin concentrations at 24 h and 48 h and sOB-R concentrations at 24 h post-exercise. However, no correlations were found between sOB-R and leptin at the three post-exercise time points. In conclusion, an acute bout of exercise with 920 kcal of output resulted in an increase in sOB-R levels at 24 h post-exercise. However, the changes in sOB-R levels due to an acute bout of exercise might not contribute to the delayed decrease observed for leptin.

    There are an increasing number of researches in science education that affirm the importance of discussions on the "nature of science" in basic education level as well as in teacher training. The history of science applied to education is a way to contextualize epistemological discussions, allowing both the understanding of scientific content and learning about science concepts. We present some reasonably consensual definitions on the nature of science that have been widely discussed by the academic community. We show also some episodes in the history of astronomy which can lead to discussions involving some aspects of the nature of science, and how they can do it. Hay un número creciente de investigaciones en la enseñanza de las ciencias que afirman la importancia de debates sobre la "naturaleza de la ciencia" en la educación básica y formación del profesorado.

    The present article is the analysis of a conversation between the author and Lara, a four-yearold- girl, enrolled in nursery school, while she makes a drawing of the Earth. It took place outside school environment and without any other person around to avoid interference during the interview. According to Ferreira & Silva (2004), a researcher can only comprehend a child's drawing, or form, by listening to him/her while he/she is creating it. Lara presented the traditional flat drawing, picturing the sky parallel to the ground, as reported by Nardi & Carvalho (1996). However, when asked to draw the World - term used by Butterworth et al. (2002), in order to avoid unnecessary confusion - she represented it by a circle, with herself on the surface. Her drawings led to the conclusion that such girl does not know yet the World in which she lives is the Earth, and probably because of that, within her age and consequent maturity, she accurately differentiates the concepts of land and Earth. El presente artículo analiza una entrevista libre, mientras una niña de 4 años y 4 meses, matriculada en el pregrado, dibuja la Tierra. Esta entrevista se realizó fuera del ambiente escolar y sin otra persona alrededor que pudiera interferir. De acuerdo con Ferreira Silva (2004), para quien investiga es posible conocer realmente lo que un niño o una niña pone en el papel a través de grafismos y/o dibujos si se lo escucha durante el proceso de creación de la escritura con imágenes. La niña, en este caso, representa la Tierra con el tradicional dibujo plano y el "cielo" paralelo al suelo, conforme analizaron Nardi & Carvalho (1996). Pero, cuando se Le solicita dibujar el "Mundo" - palabra empleada en un trabajo de Butterworth et al. (2002), con intención de no provocar "confusiones" innecesarias a sus sujetos de investigación- lo representa de forma circular, poniéndose sobre su superficie. Sus dibujos llevan a concluir que esta niña aún no tiene conocimiento que el mundo

    In this article we describe the development of a multiple choice test about lunar phases and analyze the results of its application to ten groups of Physics students at the UFRGS. During the improvement of the test, we noticed that the percentage of right answers about some concepts increased significantly when associated with the reformulation of the question, emphasizing the importance of being careful to avoid incorrect answers generated by unclear questions, and not by ignorance on the matter. We confirm the results of other studies that show that students have great difficulty to relate the Moon's phase with its position in the sky at given time. On the other hand, our results suggest that, in general, students of Physics understand the phenomenon of lunar phases better than the average of university students. En estese artículo se describe la elaboración de una prueba de opción múltiple sobre las fases de la Luna y se analizan los resultados de su aplicación en diez grupos de estudiantes de Física de UFRGS. Durante el mejoramiento de la prueba observamos que el porcentaje de aciertos creció considerablemente cuando considerada una nueva redacción de la pregunta, destacando el cuidado que se debe tomar a fin de evitar respuestas incorrectas generadas por preguntas poco claras y no a causa de la ignorancia de los estudiantes sobre el tema. Confirmamos los resultados de otros estudios que las mayores dificultades de los alumnos sobre el tema fases de la Luna están en relacionar la fase de la Luna con su posición en el cielo en determinado momento. Por otra parte, nuestros resultados sugieren que, en general, los estudiantes de la Física comprenden mejor el fenómeno de las fases lunares que el promedio de los estudiantes universitarios.

  20. Sobre a largura da última superfície de espalhamento

    2003-08-01

    De acordo com o modelo do "Big-Bang", no universo primordial a matéria estava em equilíbrio térmico com a radiação. Com a expansão a temperatura da radiação cai. Quando a temperatura chega em torno dos 4.000K, os espalhamentos diminuem, começando a recombinação dos prótons e elétrons em Hidrogênio neutro (era conhecida como da recombinação). Ao final da recombinação, os fótons se propagam livremente sofrendo, em princípio, somente os efeitos do "redshift" cosmológico. Esses fótons nos alcançam hoje como a radiação cósmica de fundo (RCF), e parecem vir de uma superfície esférica ao nosso redor, tal que o raio dela é a distância que ele viajou desde seu último espalhamento na época da recombinação. Naturalmente, esse processo não ocorreu abruptamente, implicando na existência de uma largura no espaço dos "redshifts" que deve depender do modelo cosmológico específico e dos processos físicos considerados. Neste trabalho analisamos os efeitos de diferentes modelos - a saber, aqueles com decaimento do vácuo L(t), criação de matéria, quintessência e gás de Chaplygin - sobre a última superfície de espalhamento da RCF, em particular sua largura e a função visibilidade, que determina a probabilidade de um fóton ter tido seu último espalhamento num "redshift" z. No caso particular dos modelos com decaimento do vácuo, existe uma forte dependência da função visibilidade com L(t). Tais efeitos poderão ser testados através da análise dos resultados de experimentos mais precisos que estão atualmente em andamento, como por exemplo, o WMAP.

    Resumen El objetivo de este estudio fue desarrollar fotonovelas, un tipo de novela gráfica popular en la población latina, para crear conciencia y educar sobre los trastornos de la conducta alimentaria (TCA). Cuatro caricaturas ilustradas y guiones adaptados para adultos y adolescentes de ambos sexos fueron presentados en discusiones focales y en una entrevista de profundidad. Diecisiete latinos adultos (14 mujeres; 3 hombres) y 10 adolescentes (9 féminas; 1 varón) participaron en el estudio. Los participantes encontraron las fotonovelas interesantes y que captaban más la atención que los folletos tradicionales. El uso del espanglish y la clarificación de las diferencias entre los TCA fueron sugeridos por las adolescentes femeninas. Los adultos varones sugirieron cambiar el título, que se enfocara en las consecuencias en la salud de los TCA para que llame la atención en los hombres a leer la historia. Basado en la aceptación encontrada en este estudio, la fotonovela pudiera ser una avenida prometedora para crear conciencia y educar a la comunidad latina sobre los TCA en los Estados Unidos.

  4. Human breast milk and adipokines--A potential role for the soluble leptin receptor (sOb-R) in the regulation of infant energy intake and development.

    Concentrations of different adipokines in human breast milk are thought to be able to affect energy intake of the infant. Leptin is a hormone synthesized by adipose tissue and the human placenta and favors satiety. The availability of leptin in breast milk is influenced by epithelial cells of the mammary gland that are known to be able to produce leptin, as well as leptin from maternal circulation that is transported to the breast milk, and which can thus in turn reach neonatal blood after absorption. Research so far as mainly focused on leptin concentrations in breast milk. However, evidence suggests that in addition to leptin concentrations levels of the so-called soluble leptin receptor (sOb-R), the main high-affinity binding protein for leptin in humans, are necessary in order to calculate the free leptin index (FLI) and to assess function of the leptin axis. FLI is calculated from the ratio of leptin to the sOb-R, and serves as the main parameter for assessing function of the leptin axis throughout maturation and development. Here we propose that assessing sOb-R levels in addition to leptin concentrations in breast milk could serve as a valuable tool to investigate effects of the leptin axis in breast milk because sOb-R concentrations can impact available leptin levels, and which in turn can have significant implications for infant energy intake and related development.

    RESUMEN Objetivo Mostrar, a través de un diagnóstico en América Latina y el Caribe, el panorama legislativo y curricular sobre sexualidad y prevención contra el virus de inmunodeficiencia humana (VIH) en el ámbito escolar, contrastándolo con los comportamientos sexuales reportados en encuestas demográficas y de salud. Métodos En mayo de 2008 se realizó, con el apoyo del Fondo de Población de las Naciones Unidas (UNFPA), una encuesta a informantes clave en 34 países de la Región. El cuestionario autoaplicado solicitó información sustantiva de agentes de las diferentes partes interesadas, como ministerios de educación y de salud, sobre los programas de prevención contra el VIH/Sida que se están aplicando en las escuelas. Resultados Respondieron a la encuesta 27 países que representan 95,5% de la población objetivo (6 a 18 años de edad). La mayoría de los países informó tener al menos un libro de texto o un capítulo específico para enseñar los temas de educación sobre sexualidad y prevención del VIH. En la escuela secundaria se cubren la mayor parte de los temas pertinentes relevantes para la educación sobre sexualidad, pero no todos. Por ejemplo, el problema de la discriminación por orientación o preferencia sexual no se incluye en los programas escolares. Conclusiones El material educativo sobre sexualidad debe ser revisado y actualizado periódicamente de modo que refleje los avances en los temas y en la forma de tratar los contenidos. En cada país el currículo debe abordar el tema del respeto a la diversidad sobre orientación, preferencia e identidad sexuales, y en particular el manejo apropiado de la educación para prevenir infecciones de transmisión sexual (ITS) en hombres que tienen sexo con hombres. Los esfuerzos de evaluación de la efectividad de los programas deben contemplar desenlaces tales como marcadores biológicos (incidencia y prevalencia de ITS y embarazo) y no únicamente indicadores de conocimiento y

    Averiguar la actitud y el conocimiento que tienen los estudiantes de medicina de una universidad pública del noreste de México sobre la donación de órganos y tejidos. Estudio prolectivo, descriptivo, observacional y transversal. Se incluyeron 3056 encuestas de 34 reactivos realizadas a estudiantes de medicina durante el periodo 2013-2015 y se eliminaron aquellas con menos del 80% de los reactivos contestados. Análisis estadístico: frecuencias absolutas, porcentajes, medias, desviación estándar y prueba de ji al cuadrado. Se consideró significativo un valor de p < 0.05. El 74% de los estudiantes donaría sus órganos y el 41% lo haría por reciprocidad; del 26% que no donaría sus órganos, el 48% no lo haría por temor a que tomen sus órganos antes de estar muerto. Un 86% estaría dispuesto a donar los órganos de algún familiar. El 64% ha comentado el tema de la donación con su familia y el 67% con amigos. El 50% no ha recibido información alguna sobre el tema. El 68% entiende el concepto de muerte encefálica. Pocos estudiantes reciben información sobre donación de órganos al llegar a la universidad; pese a ello, la mayoría tiene una actitud positiva y estarían -dispuestos a -donar. The issue of organ donation is scarcely addressed during undergraduate medical studies.

A 34 items cross-sectional survey evaluating knowledge and attitude towards organ donation in 3056 medicine students during 2013-2015. Descriptive statistics were used as absolute frequencies, percentages, mean and standard deviation, as well as the Chi-square test. A p < 0.05 was considered significant. 74% of students would donate their own organs, mainly due to reciprocity (41%). 26% of students would not donate, 48% of them because of fear that their organs could be taken before death

  10. Concepciones y concepciones alternativas de estudiantes universitarios/as de biologia y futuros maestros/as de Ciencia de escuela secundaria sobre la teoria de evolucion biologica por seleccion natural

    Morales Ramos, Egda M.

    La teoria de evolucion biologica (TEB) por seleccion natural es uno de los conceptos unificadores mas importantes del curriculo de Biologia. En Puerto Rico se han hecho pocas investigaciones que abunden sobre las concepciones y concepciones alternativas (CA) que tienen los estudiantes universitarios/as de Biologia y los maestros/as de Ciencia del nivel secundario sobre esta teoria. La politica publica educativa actual establece mediante documentos normativos como los Estandares de contenido y Expectativas de grado del Programa de Ciencias [Puerto Rico Core Standards] la ensenanza de esta teoria. Sin embargo, no se encontraron preguntas sobre la seleccion natural en los ejercicios de practica provistos por el Departamento de Educacion para las pruebas estandarizadas lo cual puede influir para que no se ensene adecuadamente. Las preguntas de investigacion fueron 1. ¿Cuales son las concepciones y concepciones alternativas de estudiantes universitarios/as y de los futuros maestros y maestras de Ciencia sobre la TEB? 2. ¿Cuales conceptos que seleccionan los estudiantes universitarios/as y los futuros maestros y maestras de Ciencia sobre la TEB coinciden con lo aceptado como valido por la comunidad cientifica? y 3. ¿Como comparan las respuestas de la prueba original. v. Entendiendo el cambio biologico que mide concepciones y CA sobre la TEB por seleccion natural, con las de la traducida al idioma espanol? Se utilizo el metodo cuantitativo con un diseno de investigacion transversal por encuesta. La tecnica principal para recopilar los datos fue una prueba con doce items, que formo parte de un instrumento para el cual se recopilaron diversas fuentes de evidencia acerca de su validez. Las muestras estuvieron formadas por 69 estudiantes de Ciencias Naturales y por 16 estudiantes futuros maestros y maestras del nivel secundario de la UPR-RP. Se utilizaron estadisticas descriptivas, analisis de Ji cuadrado y se calcularon los coeficientes alfa de Cronbach y de Spearman

    Estimation of abundance of mammal populations is essential for monitoring programs and for many ecological investigations. The first step for any study of variation in mammal abundance over space or time is to define the objectives of the study and how and why abundance data are to be used. The data used to estimate abundance are count statistics in the form of counts of animals or their signs. There are two major sources of uncertainty that must be considered in the design of the study: spatial variation and the relationship between abundance and the count statistic. Spatial variation in the distribution of animals or signs may be taken into account with appropriate spatial sampling. Count statistics may be viewed as random variables, with the expected value of the count statistic equal to the true abundance of the population multiplied by a coefficient p. With direct counts, p represents the probability of detection or capture of individuals, and with indirect counts it represents the rate of production of the signs as well as their probability of detection. Comparisons of abundance using count statistics from different times or places assume that the p are the same for all times or places being compared (p= pi). In spite of considerable evidence that this assumption rarely holds true, it is commonly made in studies of mammal abundance, as when the minimum number alive or indices based on sign counts are used to compare abundance in different habitats or times. Alternatives to relying on this assumption are to calibrate the index used by testing the assumption of p= pi, or to incorporate the estimation of p into the study design.

    El estigma relacionado con el VIH/SIDA continúa siendo un obstáculo para la prevención primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continúan siendo una gran preocupación para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstáculos para la investigación del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicométricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueñas y desarrollar una versión corta de la escala que pudiera usarse en escenarios clínicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueños/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contenía 12 dimensiones del estigma relacionado con el VIH/SIDA. El análisis cuantitativo corroboró 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

    El propano provee energia a mas de 143.000 vehiculos en los Estados Unidos y 23 millones en todo el mundo. Flotas de todos los Estados Unidos han implementado con exito el uso de vehiculos que funcionan con gas propano, y en la actualidad varios funcionan gracias a este gas, incluyendo autobuses escolares, lanzaderas y autobuses publicos, asi como tambien furgonetas, taxis, vehiculos utilizados por las fuerzas del orden, barredoras de calles y camiones para uso profesional. El propano tambien se utiliza con frecuencia en aplicaciones fuera de la carretera, tales como montacargas, podadoras y equipos de uso profesional y otros equipos agricolas. Las ventajas del propano incluyen la disponibilidad interna, su rendimiento y el hecho de que genera menos emisiones de gases contaminantes que otras alternativas energeticas.

  15. La utilizacion de los mapas conceptuales en la ensenanza de biologia y su efecto sobre el dominio del proceso de fotosintesis en los estudiantes universitarios

    Gonzalez Rivera, Maria M.

    Se investigo el efecto de los mapas conceptuales sobre el dominio del proceso de fotosintesis en estudiantes universitarios. La investigacion utilizo dos estrategias: mapas conceptuales individuales y mapas conceptuales colaborativos, con el fin de investigar si existen diferencias significativas en el dominio del proceso de fotosintesis. El analisis de los datos incluyo aspectos cualitativos y cuantitativos. Se desprende del estudio que el 80% de los estudiantes describen la utilizacion de los mapas conceptuales como una experiencia beneficiosa. El 70% de los estudiantes expreso que los mapas conceptuales son utiles en el aprendizaje del proceso de fotosintesis y el 61% indico que facilitan la comprension de los conceptos. Los hallazgos mas importantes del analisis cuantitativo indican que los estudiantes que utilizaron los mapas conceptuales mejoraron significativamente su desempeno en la posprueba global. Se utilizo la prueba Mann-Whitney para investigar si existian diferencias significativas en la posprueba y preprueba global, el valor de W = 1945.0, para un valor p de 0.00, lo cual establece diferencias significativas. Para determinar si existian diferencias significativas entre la posprueba y preprueba del grupo individual, se realizo la prueba nuevamente. El valor de W correspondio a 490.5, que es significativo, con un valor p de 0.00. Se concluye que existen diferencias significativas entre la ejecucion de la posprueba y preprueba del grupo individual. Los datos proveen suficiente evidencia para sostener que los estudiantes que utilizaron la estrategia de mapas conceptuales individuales mejoraron el dominio del proceso de fotosintesis significativamente. Se realizo nuevamente la prueba para los resultados de posprueba y preprueba del grupo colaborativo. El valor de W correspondio a 446 con un valor p de 0.00. Se concluyo que existen diferencias significativas entre la ejecucion de la posprueba y preprueba del grupo colaborativo. Finalmente, se efectuo una

    Cordova-Santiago, Lizzette Astrid

    La investigacion---accion que se llevo a cabo en la sala de clases tenia como punto de partida las creencias de la cultura de la ciencia de un grupo de estudiantes universitarios para luego examinar sus implicaciones en el proceso de aprendizaje de las Ciencias Biologicas. ¿Que se supone que hagan las creencias en relacion con el aprendizaje? ¿En que consiste incorporar este aspecto a la practica educativa universitaria? Utilizando el modelo de Kemmis y McTaggart (1987) la investigacion-accion se planteo como un proceso dinamico en cuatro momentos en espiral constituidos por la planificacion, la accion, la observacion y la reflexion. Cada una de las fases tuvo una intencion retrospectiva y prospectiva formando una espiral de autorreflexion del conocimiento y la accion. Se llevaron a cabo audio grabaciones en clases y analisis de documentos. Ademas, la profesora-investigadora hizo un portafolio para reflexionar sobre las creencias de la cultura de la ciencia que tienen los estudiantes y las creencias del aprendizaje que tiene la profesora y sobre como la comprension de estos elementos ayudo a mejorar su practica educativa a traves del tiempo. Los resultados obtenidos apuntan a que las creencias de la cultura de la ciencia que tiene el grupo de estudiantes son diversas. Ellos si creen que la ciencia tiene una cultura la cual describieron como: complicada y desconocida que evoluciona constantemente, que es un conjunto de metodos, que es altamente tecnologica, que resuelve problemas de salud, ayuda a interpretar la realidad del mundo que los rodea y su origen y que existen unas intersecciones entre la ciencia y el poder. Sobre las creencias del proceso de aprendizaje de la profesora-investigadora, estas senalan que el modelaje de actores, la vision de la academia que tiene ella asi como la participacion y negociacion entre todos los involucrados en el proceso educativo, son factores que inciden en el proceso de aprendizaje.

    Objetivo El objetivo de este estudio es demostrar la distinción entre engagement y trabajolismo, estudiando su relación con la calidad del sueño y el desempeño laboral. Método Un total de 447 enfermeras de 3 hospitales de Japón fueron entrevistadas mediante un cuestionario autoadministrado que incluía la escala Utrecht (UWES, Utrecht Work Engagement Scale), la Escala de Adicción al Trabajo Holandesa (DUWAS, Dutch Workaholism Scale), preguntas sobre la calidad del sueño (7 ítems) con respecto a (1) dificultad para conciliar el sueño, (2) dificultad para mantener el sueño, (3) despertar temprano por la mañana, (4) dormirse o tomar siestas durante el día, (5) somnolencia diurna excesiva en el trabajo, (6) dificultad para despertarse por la mañana, y (7) despertar cansado en la mañana, y el Cuestionario sobre Salud y Desempeño (CSD) de la Organización Mundial de la Salud. Resultados Los modelos de ecuaciones estructurales demostraron que el engagement se relaciona positivamente con la calidad del sueño y el rendimiento laboral, mientras que el trabajolismo tiene una relación negativa con la calidad del sueño y el desempeño laboral. Conclusión Los resultados indican que el engagement y el trabajolismo son conceptualmente diferentes. El primero tiene una connotación positiva, mientras que el segundo se asocia de manera negativa al bienestar (buena calidad del sueño y buen rendimiento en el trabajo). PMID:26752805

    El estudio que se presenta es de caracter cualitativo, un estudio multicasos donde se estudia la estructura logica utilizada por cuatro (4) profesores universitarios que ensenan el curso introductorio de quimica, en la planificacion, presentacion y evaluacion del tema sobre el comportamiento de los gases. Se utilizaron varias fuentes de informacion como: cuestionarios de profesores y estudiantes, entrevistas, grabaciones videomagnetofonicas, materiales didacticos y una prueba conceptual, entre otros. La informacion recopilada fue analizada de acuerdo al orden logico del contenido presentado, el estilo de ensenanza del profesor, las tecnicas y estrategias utilizadas para el desarrollo de destrezas de pensamiento, el ambiente fisico en el salon de clase y los instrumentos de evaluacion y avaluo. El estudio demuestra que lo que los profesores piensan y planifican para hacer sus presentaciones no necesariamente es lo que ocurre en el salon de clases. El desarrollo de destrezas de pensamiento, que constituye una prioridad de los profesores, no se elaboran efectivamente. El uso de las estrategias de resolucion de problemas numericos predomino. La participacion del estudiante en el salon de clases fue limitada y no se logro demostrar el desarrollo de las destrezas de pensamiento deseadas. Aunque los profesores tienen su propio estilo de ensenanza, el orden logico del contenido presentado en clase fue el mismo o siguio muy de cerca el orden establecido por el libro de texto. Los profesores utilizaron preferentemente la tiza y la pizarra para sus presentaciones y la dinamica en el salon de clases fue esencialmente tradicional. Los profesores hicieron su presentacion y los estudiantes copiaron pasivamente la informacion. Las evaluaciones de los estudiantes fueron esencialmente, pruebas escritas de seleccion multiple de acuerdo con el estilo en que se les enseno. El avaluo fue casi inexistente. La prueba conceptual administrada revela un aprendizaje pobre en los conceptos mas

    This consensus document was prepared by an expert panel of the Grupo de Estudio de Sida (GESIDA [Spanish AIDS Study Group]) and the Plan Nacional sobre el Sida (PNS [Spanish National AIDS Plan]). The document updates current guidelines on the treatment of tuberculosis (TB) in HIV-infected individuals contained in the guidelines on the treatment of opportunistic infections published by GESIDA and PNS in 2008. The document aims to facilitate the management and treatment of HIV-infected patients with TB in Spain, and includes specific sections and recommendations on the treatment of drug-sensitive TB, multidrug-resistant TB, and extensively drug-resistant TB, in this population. The consensus guidelines also make recommendations on the treatment of HIV-infected patients with TB in special situations, such as chronic liver disease, pregnancy, kidney failure, and transplantation. Recommendations are made on the timing and initial regimens of antiretroviral therapy in patients with TB, and on immune reconstitution syndrome in HIV-infected patients with TB who are receiving antiretroviral therapy. The document does not cover the diagnosis of TB, diagnosis/treatment of latent TB, or treatment of TB in children. The quality of the evidence was evaluated and the recommendations graded using the approach of the Grading of Recommendations Assessment, Development and Evaluation Working Group.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

    Based on the readings of articles related to Astronomy Education published in Brazil, it was noticed a lack of research on previous knowledge of students about the physical characteristics of stars, a fact that motivated us to develop this study. Previous knowledge of 125 students (approximated 15 years old) constituted the study sample; data was collected through written questionnaires (Appendix A) for analysis. From the content analysis of these responses it was possible to achieve some inferences as, for example, many students have some difficult to develop an explanatory model on the functioning of a star; there are few who say that the stars have a certain length of existence; some students have said that stars have tips; few recognize that a star is formed by a mass of gas; some previous knowledge come from purely visual aspects; furthermore, some students do not have the habit of observing nature in detail. We see this research as a reference in which science teachers can recognize the importance of previous knowledge for practice teaching and acquire resources for planning their lessons.

    Results from the latest generations of telescopes have revealed a rich sky at high and very high energies with more than a thousand sources at GeV energies and more than a hundred sources at TeV energies. The sources are galactic and extra-galactic natural particle accelerators where emission processes operate efficiently at the gamma-ray domain. The development of pair-photon cascades within the source or along the line of sight may modify the originally emitted spectrum. This effect should be included in our interpretation of the observations in order to progress in the understanding of the physical origin of the emission. Through numerical simulations; we follow the three-dimensional trajectories of such cascades. I here report on the status of our investigations; with focus on the propagation through the background photon fields. FULL TEXT IN SPANISH

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students.

    This paper presents one of the concepts of Astronomy and its consequent failure in teaching this topic in high school, even when the official documents point out the necessity of Astronomy teaching at this school level. Among the spontaneous conceptions in Astronomy that high school students carry with them, even after the end of the school, we emphasized in this research the Moon phases. The development of different strategies in relation to traditional methods, aimed to teaching-learning process on this topic was considered in this study. These strategies were devised based on the reference frame of the Meaningful Learning, as elaborated by Ausubel. The proposals presented here include the active participation of students in experimental activities and other didactic activities, for their continuous evaluation during the process. These activities finished with a Comics elaboration about the Moon phases. Therefore, the objective of this paper is to present a proposal for differentiated teaching activity about Moon phases supported by the theoretical principles of Meaningful Learning at Physics classes. Este texto foca um dos conteúdos de Astronomia e a consequente falha no ensino deste tema no ensino médio, apesar de os documentos oficiais apresentarem a necessidade de se trabalhar a Astronomia neste nível de ensino. Dentre as concepções alternativas em Astronomia que os alunos do ensino médio carregam consigo, mesmo após o término dos estudos, destacamos, nesta pesquisa, o fenômeno das fases da Lua. O desenvolvimento de estratégias diferenciadas em relação ao ensino tradicional, visando o processo de ensino-aprendizagem sobre este tema, foi contemplado neste trabalho como um dos resultados obtidos sob a luz dos referenciais da aprendizagem significativa, fundamentados em Ausubel. Segundo a proposta aqui apresentada, a participação ativa dos alunos na execução de uma atividade experimental e outras atividades didáticas, que visam sua cont

    El propósito de este trabajo es presentar el impacto y la integración que los conocimientos adquiridos en el Programa Internacional de Formación en Ética de la Investigación Biomédica y Psicosocial de la Universidad de Chile han tenido en mi experiencia profesional, en el ámbito de la investigación psicosocial en un Instituto de Salud de México. Para este objetivo, expondré tres áreas en las cuales se ha podido evidenciar tal impacto: trabajo en los comités de ética, desarrollo de programas de académicos en bioética e investigación y publicación sobre ética y bioética. El motivo que me llevó a incursionar en el Programa fue que su enseñanza vincula la investigación psicosocial con la ética y la bioética, lo cual me permitió dirigir este tipo de reflexión hacia problemas como violencia, suicidio, adicciones, depresión y salud mental, y a nuevos campos como los estudios comunitarios, con poblaciones en riesgo o vulnerables, en los cuales las diversas implicaciones son difíciles de indagar.

    PubMed

    Artigas-Pallares, J; Paula-Perez, I

    2016-01-01

    Introduccion. La investigacion sobre el autismo, basada principalmente en el modelo categorico del Manual diagnostico y estadistico de los trastornos mentales, se ha centrado de forma preferente en la epidemiologia, las manifestaciones clinicas, los mecanismos cognitivos y los determinantes biologicos y ambientales; sin embargo, se ha prestado escaso interes a las trayectorias evolutivas, las cuales son decisivas de cara al pronostico a medio y largo plazo. Objetivo. Revisar el curso evolutivo de niños diagnosticados de autismo que, aun conservando a medio o largo plazo rasgos conductuales acordes con el perfil inicial, alcanzan una adaptacion social y laboral satisfactorias, y ademas dejan de cumplir los criterios que dieron lugar al diagnostico inicial. Desarrollo. Se ha revisado la bibliografia sobre el autismo centrada en el analisis de la evolucion de las manifestaciones clinicas y de su repercusion desde las primeras edades hasta la edad adulta. Asimismo, se han tomado en consideracion aspectos conceptuales sobre el autismo que facilitan la comprension y el significado de los patrones evolutivos. Conclusiones. Alrededor del 20% de los niños diagnosticados dejan de cumplir los criterios en los que se baso el diagnostico y, ademas, alcanzan un ajuste social y laboral satisfactorio. Como factores favorecedores se identifica: inteligencia normal, buen nivel de lenguaje y baja incidencia de 'comorbilidades'; por el contrario, en las series notificadas no se señalan como factores determinantes las intervenciones terapeuticas precoces e intensivas. Por ultimo, se menciona el concepto de neurodiversidad, donde la recuperacion se centra en el desarrollo optimo de las capacidades de cada individuo en un entorno facilitador.

    This article presents results of a research which aimed to understand the meanings that people construct for astronomical observation. The subjects, students and school teachers, initially received some instruction on how to view astronomical objects through the telescope. After the observation was realized, they were interviewed. The data analysis allowed the creation of 12 categories, later interpreted on the basis of relationship with knowledge (relation to the world, with himself and with others), as presented by Bernard Charlot.

    Although previous studies show that robotic telescopes have the potential to enhance student learning, there is comparatively little research that focuses on teacher perceptions of this technology. This study investigates: "what is the academic merit of using SLOOH robotic telescopes to teach astronomy as perceived by science teachers?" Our sample consists of nine science teachers of students aged 13-18 years. Pre- and post-tests, interviews, and surveys were collected during two weeks of a summer online course about robotic telescopes. While pre and post-tests do not reveal a statistically significant gain in astronomy content knowledge, analysis of qualitative data reveals five themes which describe the most important aspects of using SLOOH according to participants: "Images," "Interface," "Classroom Application," "Instructor Impact," and "Logistical Issues." Analysis of these themes suggests that SLOOH can provide an interactive and social learning environment with capabilities to incorporate crossdisciplinary themes. Embora estudos anteriores mostram que os telescópios robóticos têm o potencial de melhorar a aprendizagem dos alunos, há relativamente pouca investigação focada nas percepções de professores a respeito desta tecnologia. Este estudo investiga: "qual é o mérito acadêmico da utilização de telescópios robóticos Slooh para ensinar astronomia, tal como percebido pelos professores de ciências?" Nossa amostra é composta por nove professores de ciências de estudantes com idades entre 13-18 anos pré e pós-testes, entrevistas, e levantamentos foram coletados durante duas semanas de um curso on-line de verão sobre telescópios robóticos. Enquanto os testes pré e pós não revelaram um ganho estatisticamente significativo no conhecimento do conteúdo astronomia, a análise de dados qualitativos revela cinco temas que descrevem os aspectos mais importantes da utilização Slooh de acordo aos participantes: "Imagens", "Interface", "Aplica

    Our main aim of this work is to analyze 2 phenomena possibly related and at the same time very discussed in the literature. On the one hand, the difference in the activity levels shown by stars with and without planets. On the other hand, the excess of Lithium (Li) depletion presented by stars with planets when they are compared to stars with similar characteristics that do not host planets. To reach our main aim, the work has been divided into 3 stages. Thus, in this second contribution we present an analysis of the activity indexes calculated for the whole sample. To do so, we used high resolution spectra () of 1004 FGK stars taken with the HARPS (High Accuracy Radial Velocity Planet Searcher) spectrograph, installed in the 3.6 m ESO telescope. We do not find a significant difference in the activity indexes of stars with and without planets. Furthermore, the chromosphere activity is not correlated with the mass of the planet.

    The aim of this work is to analize the possible difference in the levels of activity showed by stars with and without planets. Several authors have suggested that stars with planets, in particular those with hot-Jupiter-like planets, have activity levels greater than those showed for stars of the same spectral class, but without planets. In this contribution we present the analysis of chromospheric activity indexes for 353 objects. To do so, we used high-resolution spectra () of F-, G-, and K-type stars taken with the High Accuracy Radial velocity Planet Searcher spectrograph, installed at the 3.6 m ESO telescope. We do no find a significant difference in the activity indexes of stars with and without planets.

    Introduccion. Los niños con trastorno por deficit de atencion/hiperactividad (TDAH) presentan alteraciones en los mecanismos atencionales y en los procesos de control inhibitorio (impulsividad e hiperactividad), que afectan de distinta manera a su rendimiento academico, socioemocional y conductual, por lo que es fundamental la consideracion de estrategias de intervencion en el ambito psicopedagogico que puedan incidir de forma favorable en el curso evolutivo de los afectados. Objetivo. Revisar las bases psicopedagogicas en la intervencion sobre el TDAH, considerando la relacion de la anatomia funcional con la sintomatologia clinica y los correspondientes programas de intervencion. Desarrollo. Se destacan los tres sindromes preferentes: orbitofrontal, dorsolateral y en el cingulo a nivel medial. Las fases de la intervencion psicopedagogica deben abarcar tanto al niño como a la familia y el colegio. El entrenamiento neurocognitivo se centra en el niño, basado en programas de entrenamiento de las funciones ejecutivas y en las actuaciones sobre el ambito academico, conductual y socioafectivo. Los programas de modificacion de conducta son complementarios y en muchas ocasiones mejoran el comportamiento comprometido en los niños con TDAH. Las orientaciones psicopedagogicas en la escuela deben considerarse necesarias para una intervencion eficaz en el entorno academico. Conclusiones. La intervencion psicopedagogica de los niños con TDAH debe contemplar la individualizacion del tratamiento dentro de una metodologia multidisciplinar, teniendo en cuenta todos los contextos en los que se desarrolla el niño, su rendimiento cognitivo y las intervenciones farmacologicas apropiadas en cada caso.

    Some studies suggest that, upon admission, medicine programs students display eagerness for community service, aspirations to be useful, and to contribute to society's well-being. Those same studies reflect that qualities of idealism, moral nature, and internal motivation, suffer a subsequent diminishing. The researchers inferred that the main reason for this process of change in the mood and disposition of these future physicians lies in the modeling they receive from medical professionals throughout clinical learning activities, by way of behavior and relationships exhibited during daily interaction with peers, patients and the students themselves. This phenomenological study used a cross-sectional sample to explore the experiences of future health workers as they went through didactic and clinical phases of their training curriculum. The study employed semi-structured interviews and reflective journals to explore those experiences and to discover the meanings ascribed by the participants. The analysis revealed that the students defined "professionalism" in terms of scientific knowledge, commitment, respect for human dignity, comradeship, courtesy, empathy, integrity, altruism, motivation. They also described their feelings as they went through the didactic and clinical experiences, and recognized as very important the extracurricular activities of community service, describing them as useful opportunities which contributed to understand their work in terms of a mission dedicated to the achievement of the social benefit. From their individual perspectives, the clinical environment could, in general, be described as congruent with those characteristics of professionalism. During the study we had the opportunity to share, in a little deeper way, the environment... the world... of this small group of young students as we went on trying to decipher their feelings and thoughts. At the end, we realized the richness of their sensibilities, we perceived the intensity of their moral and ethical convictions, we were able to understand their concerns, worries, struggles and efforts. This life event had profound and significant repercussions in our personal and professional life. As a result, and from now on, we will no longer look at our young scholars and apprentices without imagining a noble spirit, with goals which at times could seem unattainable... without completely visualizing or conceiving real hope for a better country.

  14. Modelo analítico del efecto de PRS sobre satélites GPS

    NASA Astrophysics Data System (ADS)

    Meza, A.; Brunini, C.; Usandivaras, J. C.

    El sistema GPS (Global Position System) es, hoy en día, la herramienta de navegación y posicionamiento más potente y lo será sin duda en la próxima década. Gran parte de su valiosa utilidad se debe a la alta precisión que permite lograr y ésta, a su vez, depende, entre otras causas, de la precisión con que se conocen las órbitas de los satélites. La presión de radiación solar (PRS) fija el límite de la precisión con que pueden calcularse en la actualidad las efemérides satelitarias. El objetivo de este trabajo es proponer una mejor resolución de este fenómeno. El modelo analítico aquí presentado, se basa en el análisis del comportamiento de los residuos de un ajuste por mínimos cuadrados en el que se utiliza el modelo de PRS propuesto por Beutler. El mismo consiste en un modelo determinista del fenómeno con dos parámetros libres. Los resultados obtenidos ponen de manifiesto que, aún después de aplicar dichos parámetros, prevalecen en los residuos efectos semidiurnos en las componentes radial,tangencial y normal. Estos resultados obtenidos se comparan con los de un trabajo desarrollado por el Instituto de Berne (Beutler et al., 1994), en el que se utilizaron como pseudo-observaciones las órbitas precisas del IGS (CODE). El intervalo de integración escogido por este centro fueron las semanas 680 y 681. En resumen se tienen arcos de 14 días para todos los satélites, donde las efemérides precisas de los mismos para los 14 días fueron utilizados como pseudo-observaciones. El modelo de fuerza que empleó dicho centro fue básicamente el tradicional en lo que respecta al modelo de las fuerzas gravitacionales, y para la PRS utilizo el modelo standard de Beutler. Los parámetros de este modelo junto con las 6 condiciones iniciales (posición y velocidad) fueron ajustados por el método general de mínimos cuadrados. Los residuos en la componente radial, tangencial y normal, para los satélites con un buen comportamiento, presentan una componente semidiurna. El modelo analítico planteado en este trabajo, predice el comportamiento de los residuos que se observan en las publicaciones más recientes. Esto abre el camino para plantear una estimación distinta de las incógnitas del problema, basado en el método de colocación por mínimos cuadrados. Ello requiere modelar estadísticamente la señal debida a las componentes de la PRS que no son tomadas en cuenta en el modelo determinista.

    2003-08-01

    Neste trabalho é apresentada uma demonstração do uso dos diferentes desenvolvimentos em séries para as equações de perturbação em Mecânica Celeste no marco Hamiltoniano. Em trabalhos clássicos como os de Poincaré (Poincaré, 1893) por exemplo, já esta planteado o uso de potências não inteiras no pequeno parâmetro, o que evidencia a não analiticidade das funções quando uma ressonância ocorre. Nestes trabalhos os desenvolvimentos são na raíz quadrada da massa de Júpiter (o pequeno parâmetro). Mais recentemente (Ferraz-Mello, 1985) outros tipos de desenvolvimentos foram aplicados modificando substancialmente as ordens de grandeza e a velocidade de convergência das séries. Com esta abordagem, os desenvolvimentos foram expressados em termos da raíz cúbica do pequeno parâmetro. Neste trabalho apresentamos um enfoque geral, onde os diferentes tipos de desenvolvimentos em séries de Puiseux (Valiron, 1950) são obtidos a partir da aplicação de Teorema de Preparação de Weierstrass (Goursat, 1916) considerando a equação de Hamilton-Jacobi como uma equação algébrica. Os resultados são aplicados ao problema restrito dos três corpos em ressonância de primeira ordem e, dependendo da grandeza da excentricidade do asteróide em relação à de Júpiter, obtemos os diferentes desenvolvimentos, em raíz quadrada ou raíz cúbica da massa de Júpiter.

    Ballesteros Benavides, Maria Elvira

    Para este trabajo utilizamos el estudio de casos cualitativo que se llevo a cabo en una universidad privada de Puerto Rico. Empleamos como unidad de analisis el concepto de enlace quimico, ionico y covalente. Los participantes fueron los estudiantes de la seccion nocturna del curso de Quimica General I. La investigacion se desarrollo por medio de dos entrevistas de persona a persona, observaciones de las expresiones no verbales y la hoja de identificacion de conceptos. Para la triangulacion tomamos en consideracion las preconcepciones erroneas, las concepciones alternativas y el mapa de conceptos de cada participante. Preparamos un mapa de conceptos para el enlace quimico validado por un comite de expertos. Tambien, elaboramos los mapas de conceptos de los participantes que sirvieron para varios propositos: conocer la estructura conceptual, expresar los logros, hacer comparaciones e identificar la presencia de concepciones alternativas. Entre los hallazgos encontramos que todos los participantes poseen conocimiento previo de los enlaces quimicos ionico y covalente y dentro de ese conocimiento existen preconcepciones erroneas mas numerosas para el enlace ionico. Al principio del semestre el 50% de los participantes demostraron tener "carencia fuerte de conceptos" tanto para el enlace ionico como para el covalente. Al finalizar el semestre encontramos en el 40% de los participantes concepciones alternativas tanto para el enlace ionico como para el covalente y el 90% no lograron distinguir un enlace del otro. Nuestras conclusiones fueron que los participantes sin distincion del aprovechamiento academico demostraron tener la tendencia de "carencia fuerte de conceptos" tanto para el enlace ionico como para el covalente, presentaron dificultad al integrar los conceptos de los enlaces quimicos ionico y covalente que se pusieron de manifiesto al dar los ejemplos. Las preconcepciones erroneas contribuyen en el desarrollo de las concepciones alternativas. Ademas, los

    Servicios Ambientales Culturales Resumen Los deseos, necesidades y valores no materiales de los accionistas influyen frecuentemente sobre el éxito de los proyectos de conservación. Estas consideraciones son difíciles de articular y caracterizar, lo que resulta en entendimiento limitado en el manejo y la política. Concebimos un protocolo de entrevista diseñado para mejorar el entendimiento de los servicios ambientales culturales (SAC). El protocolo inicia con la discusión de actividades relacionadas con ecosistemas (p. ej.: recreación, cacería) y manejo; después señala a los SAC, dando pie a los valores que encierran conceptos identificados en la Evaluación Ambiental del Milenio (2005) y explorado en otras investigaciones sobre SAC. Hicimos pruebas piloto del protocolo en Hawái y Columbia Británica. En cada localidad entrevistamos a 30 individuos de diversos entornos. Analizamos los resultados de las dos localidades para determinar la efectividad del protocolo de entrevista en la obtención de valores no materiales. Los componentes cualitativos y espaciales del protocolo nos ayudaron a caracterizar los valores culturales, sociales y éticos asociados con el ecosistema de múltiples maneras. Los mapas y las preguntas de situación, o de tipo viñeta, ayudaron a los encuestados a articular valores difíciles de discutir. Las preguntas abiertas permitieron a los encuestados expresar una diversidad de valores ambientales y demostraron ser suficientemente flexibles para que los encuestados comunicaran valores que el protocolo no buscaba explícitamente. Finalmente, los resultados sugieren que ciertos valores, aquellos mencionados frecuentemente en la entrevista, son particularmente prominentes para poblaciones particulares. El protocolo puede proporcionar datos eficientes, contextuales y basados en lugar sobre la importancia de atributos ambientales particulares para el bienestar humano. Los datos cualitativos son complementarios para las evaluaciones cuantitativas y

Our hope is that a study along these lines can help to illuminate current understandings of questions related to sexuality both within and outside of the religious contexts found in contemporary Brazil. Such questions are of special interest for those who are concerned with both old and new problems found in the field that has come to be known as sexual and reproductive rights, with implications for the field of Public Health.

    Embora os Parâmetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as orientações complementares a esses Parâmetros (PCN+) apontem a importância de uma abordagem significativa de conceitos relacionados à astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano. Este trabalho tem por objetivo analisar os conhecimentos básicos em astronomia dos alunos de EM da escola estadual Batista Renzi, bem como investigar os meios através dos quais estes conhecimentos foram adquiridos. Para tanto foi elaborado um questionário de múltipla escolha aplicado a 310 alunos distribuídos entre as três séries do EM dos períodos matutino e noturno. Dessa forma, observou-se que apenas 34,5% relacionaram as estações do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influência gravitacional da Lua e do Sol como responsáveis pelo fenômeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distância e 34,2% reconheceram uma estrela cadente como meteoro. Em contrapartida, 67,1% compreendiam a sucessão entre dia e noite, 73,9% identificaram o Sol como estrela e 52,3% relacionaram o Big Bang à origem do Universo. Além disso, foram comparadas as respostas de alunos de diferentes séries e períodos, observando-se, dentre outras coisas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tópicos relacionados à astronomia no EM não tem contribuído para uma maior compreensão dos fenômenos e conceitos.

    Recent developments in three-dimensional echocardiography have made it possible to obtain images in real time, without the need for off-line reconstruction. These developments have enabled the technique to become an important tool for both research and daily clinical practice. A substantial proportion of the studies carried out using three-dimensional echocardiography have focused on the mitral valve, the pathophysiology of mitral valve disease and, in particular, functional mitral regurgitation. The aims of this article were to review the contribution of three-dimensional echocardiography to understanding of the functional anatomy of the mitral valve and to summarize the resulting clinical applications and therapeutic implications.

    The aims of this multicenter study was to establish the level of primary and acquired drug resistance of M. Tuberculosis strains isolated in Barcelona and to identify possible risk groups using clinical data. All tuberculosis patients with isolation and identification of M. tuberculosis strains from October 1995 to September 1997 were included. Susceptibility tests isoniazid, rifampin, ethambutol, streptomycin and pyrazinamide were performed using the Bactec 460 system and the proportions method on solid medium. Logistic progression was used for statistical analysis. The total number of patients included was 1,749 (1,535 non-treated and 214 previously treated). Primary drug resistance was 5.7% (isoniazid 3.8%; rifampin 1.0%, streptomycin 2.1%, ethambutol 0.3% and pyrazinamide 1.0%). Acquired drug resistance was 20.5% (isoniazid 17.3%, rifampin 9.8%, ethambutol 1.9%, streptomycin 4.7% and pyrazinamide 6.5%). Primary drug resistance was associated with people over 60 years old and women. The low level of drug resistance enables antituberculosis treatment of non-treated patients to start with the standardised three-drug regimes except in the case of foreign people from countries with a high level of drug resistance. Susceptibility tests are recommended on all M. tuberculosis strains isolated, together with controlled studies of drug resistance surveillance.

  3. Estudio numerico y experimental del proceso de soldeo MIG sobre la aleacion 6063--T5 utilizando el metodo de Taguchi

    NASA Astrophysics Data System (ADS)

    Meseguer Valdenebro, Jose Luis

    Electric arc welding processes represent one of the most used techniques on manufacturing processes of mechanical components in modern industry. The electric arc welding processes have been adapted to current needs, becoming a flexible and versatile way to manufacture. Numerical results in the welding process are validated experimentally. The main numerical methods most commonly used today are three: finite difference method, finite element method and finite volume method. The most widely used numerical method for the modeling of welded joints is the finite element method because it is well adapted to the geometric and boundary conditions in addition to the fact that there is a variety of commercial programs which use the finite element method as a calculation basis. The content of this thesis shows an experimental study of a welded joint conducted by means of the MIG welding process of aluminum alloy 6063-T5. The numerical process is validated experimentally by applying the method of finite element through the calculation program ANSYS. The experimental results in this paper are the cooling curves, the critical cooling time t4/3, the weld bead geometry, the microhardness obtained in the welded joint, and the metal heat affected zone base, process dilution, critical areas intersected between the cooling curves and the curve TTP. The numerical results obtained in this thesis are: the thermal cycle curves, which represent both the heating to maximum temperature and subsequent cooling. The critical cooling time t4/3 and thermal efficiency of the process are calculated and the bead geometry obtained experimentally is represented. The heat affected zone is obtained by differentiating the zones that are found at different temperatures, the critical areas intersected between the cooling curves and the TTP curve. In order to conclude this doctoral thesis, an optimization has been conducted by means of the Taguchi method for welding parameters in order to obtain an improvement on mechanical properties in aluminum metal joint. Los procesos de soldadura por arco electrico representan unas de las tecnicas mas utilizadas en los procesos de fabricacion de componentes mecanicos en la industria moderna. Los procesos de soldeo por arco se han adaptado a las necesidades actuales, haciendose un modo de fabricacion flexible y versatil. Los resultados obtenidos numericamente en el proceso de soldadura son validados experimentalmente. Los principales metodos numericos mas empleados en la actualidad son tres, metodo por diferencias finitas, metodos por elementos finitos y metodo por volumenes finitos. El metodo numerico mas empleado para el modelado de uniones soldadas, es el metodo por elementos finitos, debido a que presenta una buena adaptacion a las condiciones geometricas y de contorno ademas de que existe una diversidad de programas comerciales que utilizan el metodo por elementos finitos como base de calculo. Este trabajo de investigacion presenta un estudio experimental de una union soldada mediante el proceso MIG de la aleacion de aluminio 6063-T5. El metodo numerico se valida experimentalmente aplicando el metodo de los elementos finitos con el programa de calculo ANSYS. Los resultados experimentales obtenidos son: las curvas de enfriamiento, el tiempo critico de enfriamiento t4/3, geometria del cordon, microdurezas obtenidas en la union soldada, zona afectada termicamente y metal base, dilucion del proceso, areas criticas intersecadas entre las curvas de enfriamiento y la curva TTP. Los resultados numericos son: las curvas del ciclo termico, que representan tanto el calentamiento hasta alcanzar la temperatura maxima y un posterior enfriamiento. Se calculan el tiempo critico de enfriamiento t4/3, el rendimiento termico y se representa la geometria del cordon obtenida experimentalmente. La zona afectada termicamente se obtiene diferenciando las zonas que se encuentran a diferentes temperaturas, las areas criticas intersecadas entre las curvas de enfriamiento y la curva TTP. Para finalizar el trabajo de investigacion se ha realizado una optimizacion, con la aplicacion del metodo de Taguchi, de los parametros de soldeo con el objetivo de obtener una mejora sustancial en las propiedades mecanicas de las uniones metalicas de aluminio.

    In this paper I propose to reflect upon modern configuration of technique, i.e., technoscience, and our responsibility towards environmental management. I show that the technological products of our world imply a certain attitude of aggression towards nature, contrasting with the attitude of protection from her, which was peculiar of the pre-technological world. Finally I suggest recovering the classical notion of politics as a possible alternative for controlling techno-scientific imperatives.

    Los arrecifes de coral son estructuras sólidas, biomineralizadas que protegen comunidades costeras actuando como barreras protectoras de peligros tales como los huracanes y los tsunamis. Estos proveen arena a las playas a través de procesos naturales de erosión, fomentan la industria del turismo, las actividades recreacionales y proveen hábitats pesqueros esenciales. La conti-nua degradación mundial de ecosistemas de arrecifes de coral está bien documentada. Existe la necesidad de enfoque y organización de la ciencia para entender los procesos complejos físicos y biológicos e interacciones que están afectando el estado de los arrecifes coralinos y su capacidad para responder a un entorno cambiante.

    2016-08-01

    White dwarfs are found to be good laboratories for studying the properties of fundamental particles such as the hypothetical axions. If these particles exist and interact with electrons, they would be emitted from the dense interior of white dwarfs, abandoning these stars without interact again, becoming an important energy sink. This would have a detectable effect on the evolutionary and pulsational properties of white dwarfs. This effect was already studied for DA white dwarfs (white dwarfs with a surface rich in hydrogen), but not for DB white dwarfs (hydrogen-deficient white dwarfs). We studied the general effect of axion emission on the evolution of DB white dwarfs and on the pulsational properties of DBV white dwarfs (pulsating DBs) with the aim of determining the potential of these stars to study the physics of axions. Moreover, we use an estimation of the rate of change of period of the DBV white dwarf PG 1351489 corresponding to the dominant period to derive a new limit on axion mass.

  1. Sobre la naturaleza de cinco candidatos a cúmulos abiertos ubicados próximos a la dirección del centro galáctico

    NASA Astrophysics Data System (ADS)

    Piatti, A. E.; Clariá, J. J.

    CCD BVI Johnson-Cousins observations obtained for 1759 stars in 4'×4' regions around the unstudied southern stellar aggregates Ruprecht 103, 124, 129, 146 and 166 are presented. The objects are described as open clusters in the catalogues of star clusters and associations of Alter et al. (1970) and LyngÅ (1987), as well as, in the ESO/Uppsala Survey of the ESO (B) Atlas (Lauberts 1982). Our analysis shows that none of these objects are genuine open clusters, except perhaps Ruprecht 166, since no clear main sequences (MSs) or other meaningful features can be seen in the extracted (V,B-V) and (V,V-I) colour-magnitude diagrams (CMDs). The star sequences seen in the distinct CMDs, specially for Ruprecht 124 and 129, are apparently formed by the superimposition of MS field stars affected by varying amounts of interstellar absorption and/or placed at different distances from the Sun. The CMDs of Ruprecht 166 present a pronounced variation in the luminosity function along the apparent MS, a fact from which we can infer the notion of these stars had a different origin. Star counts carried out within and outside the cluster candidate fields not only support the results that the objects do not present a significant number density contrast with respect to the Galactic disk, but also show that they do not appear to be candidate late stages of star cluster dynamical evolution. Several other stellar aggregates included in open cluster catalogues have previously been disproved as genuine physical systems (see, e.g., Carraro & Patat 1995, MNRAS, 276, 563; Carraro 2000, A&A, 357, 145; Piatti & Clariá 2001, A&A, 370, 931). Thus, the present work implies the potential likelihood of other wrongly classified open clusters.

    NASA Astrophysics Data System (ADS)

    Clariá, J. J.; Dutra, D. M.; Bica, E.; Piatti, A. E.

    Based on recent results obtained with the Hubble Space Telescope, we present a census of genuine globular clusters in the Large Magellanic Cloud (LMC) and we examine their spatial distribution. Spectroscopic observations carried out at Complejo Astronómico El Leoncito (CASLEO, Argentina) allow us to add two new clusters (NGC 1928 and NGC 1939) to the list of genuine LMC globular clusters. We present evidence that old clusters projected on the LMC bar region may constitute a population II core, probably reminiscent of an ancient bulge, which together with a central disc could have evolved into the observed LMC bar by SMC and/or Galaxy interactions. A detailed discussion was given in MNRAS 305, 373 (1999).

  18. Conservación de material histórico sobre papel en el Observatorio Astronómico de la Universidad Nacional de Córdoba

    NASA Astrophysics Data System (ADS)

    Laguzzi, N.; Tonini, A.; Andreoli, G.; Goldes, G.; Paolantonio, S.; Cequeira, F.; Landi, L.; Alba, J.

    At the recently created Astronomical Museum ``Pte. Sarmiento - Dr. Benjamin Gould", the task of preventive conservation of historic documents has been faced. These materials include: 1) letters exchanged between national authorities and the directors of the Observatory, during the first decades (1870-1880-1890); b) original observation logs from these very first times, containing astrometrical and photometrical data; c) a variety of ancient books and papers; d) administrative documents. The state of conservation of this patrimony was varied: since well-conserved books and letters, to highly degraded logs. The observation logs written by B. Gould and the astronomers who followed him had been stocked in a safe with a permanent humidity of about 70 %, without any ventilation and exposed to the attack of insects of the family ``dermestidae." These conditions could not be worse for the conservation of paper. In order to stop the proccess of degradation and create a healthy environment for written-paper conservation, a team was formed with personnel belonging to the Cultural Area of the Municipality. The tasks being performed on the observation logs are: 1) an initial, mechanical cleaning, performed once the material is extracted from the contaminated safe: by these means, adult insects and pupas are removed 2) a stage of about two weeks of duration, in which the logs are mantained in a vacuum chamber, in orden to completely eliminate the adult, pupa and egg stage insects by anoxia 3) the final mechanical cleaning 4) storage in a clean location. In order to perform these tasks, we work in collaboration with the Environmental Observatory of the City, and the group of Material-Science Research of Fa.M.A.F. Regarding the letters, a mechanical cleaning was performed. After that, the letters were digitized by means of a scanner, inventoried, put inside acid-free polipropylene envelops and filed for conservation, protected from intense light and external sources of contamination. Copies of these letters will be included as exhibits.

    G53.6-2.2 is a supernova remnant with an unusual morphology: in the radio band the overall shape can be described as two shells that overlap on the NW side of the remnant. The X-ray emission fills the source and peaks in the region where the radio rings overlap; while in the optical range the emission consists of filaments that correlate with portions of radio rings that overlap in the NW. The aim of the present project is to investigate the neutral hydrogen distribution around the remnant in search for signatures that allow to disclose the role of the surrounding gas in conditioning the observed morphology.

    NASA Astrophysics Data System (ADS)

    Escudero, C. G.; Faifer, F. R.; Bassino, L. P.; Calderón, J. P.; Caso, J. P.

    We present a preliminar photometric study of the globular cluster system (GCS), associated to the lenticular galaxy (S0) NGC 6861, which is located in a low density environment (d˜31.8 Mpc). It is based on GEMINI/GMOS images (GS-2010B-Q-2: PI Lilia P. Bassino) in the filters g', r', i' of three fields, one of them centered in the galaxy. We find a large number of GCs candidates and detect the presence of at least two sub-populations of GCs (``blue''/metal-poor and ``red''/metal-rich). The spatial distribution of ``red'' candidates presents a higher concentration toward the galaxy (associated to the bulge?), while the distribution of ``blue'' candidates is more homogeneus over the three fields (associated to the halo?). In the color-magnitud diagram, the ``blue'' GC candidates show a possible mass-luminosity relation, known as ``blue-tilt'', probably detected for the first time in a lenticular galaxy.

    2008-03-11

    This study sought to assess the incidence, predictors, and outcome of drug-eluting stent(DES) thrombosis in real-world clinical practice. The DES thromboses in randomized trials could not be comparable to those observed in clinical practice, frequently including off-label indications. We designed a large-scale, nonindustry-linked multicentered registry, with 20 centers in Spain. The participant centers provided follow-up data for their patients treated with DES, reporting a detailed standardized form in the event of any angiography-documented DES-associated thrombosis occurring. Of 23,500 patients treated with DES, definite stent thrombosis(ST) developed in 301: 24 acute, 125 subacute, and 152 late. Of the late, 62 occurred >1 year(very late ST). The cumulative incidence was 2% at 3 years. Antiplatelet treatment had been discontinued in 95 cases(31.6%). No differences in incidences were found among stent types. Independent predictors for subacute ST analyzed in a subgroup of 14,120 cases were diabetes, renal failure, acute coronary syndrome, ST-segment elevation myocardial infarction, stent length, and left anterior descending artery stenting, and for late ST were ST-segment elevation myocardial infarction, stenting in left anterior descending artery, and stent length. Mortality at 1-year follow-up was 16% and ST recurrence 4.6%. Older age, left ventricular ejection fraction <45%, nonrestoration of Thrombolysis In Myocardial Infarction flow grade 3, and additional stenting were independent predictors for mortality. The cumulative incidence of ST after DES implantation was 2% at 3 years. No differences were found among stent types. Patient profiles differed between early and late ST. Short-term prognosis is poor, especially when restoration of normal flow fails.

    Resumen La construcción de roles de género dominantes contribuyen al riesgo de contraer VIH, y por tal razón se ha urgido a que se integren las normas sociales relativas al género en las intervenciones preventivas del VIH. Este estudio pretende adaptar y desarrollar una intervención que facilite la transformación de normas sociales del género y de prácticas sexuales en hombres puertorriqueños. La intervención propone transformar normas sociales relacionadas al género y sexualidad en barras comunitarias utilizando el modelo de líderes de opinión. Luego de ser elegidos/as, los/as líderes de opinión diseminan mensajes integrando la importancia de relaciones equitativas entre parejas para la prevención del VIH. La primera fase de esta intervención es discutida en este artículo, la cual incluye un proceso de etnografía acelerada para identificar los escenarios comunitarios en los que podemos desarrollar esta intervención y permitirnos entender la cultura de las barras comunitarias. A partir de las observaciones etnográficas, pudimos: desarrollar un protocolo de seguridad para realizar las observaciones, desarrollar un perfil de la cultura de las barras, elegir las barras a participar en las dos condiciones del estudio y adaptar los instrumentos de la intervención para que respondieran a la particularidad de los/as participantes.

  17. Desarrollo de un instrumento para medir percepciones sobre el contexto de construccion del conocimiento cientifico de estudiantes universitarios de nuevo ingreso

    NASA Astrophysics Data System (ADS)

    Garcia-Ramirez, Jaime Antonio

    En esta investigacion, se desarrollo un instrumento que permite medir percepciones relacionadas al contexto de constriccion del conocimiento cientifico. Se examinaron instrumentos existentes y se encontro que el VOSTS (Views on science, technology, and society), instrumento desarrollado empiricamente en Canada por Aikenhead, Ryan y Fleming, podia traducirse y validarse en el contexto cultural puertorriqueno. El instrumento es extenso, consta de 113 reactivos, cada uno con una premisa basica relacionada a la tematica ciencia, tecnologia y sociedad y un numero de alternativas relacionadas a la premisa que oscila entre siete y trece. Se delimito su utilizacion a los quince reactivos identificados por los autores como relacionados a la construccion social del conocimiento cientifico. Metodologicamente, se procedio a utilizar el modelo de adaptacion intercultural, que permite que el instrumento desarrollado satisfaga las dimensiones de equivalencia semantica, de contenido, tecnica, de criterio y conceptual, atemperado asi al instrumento original. Se cumplio con este proposito mediante la traduccion de la version original en ingles al espanol y viceversa. Se utilizaron comites para examinar la traduccion y la retro-traduccion del instrumento. Se realizo una prueba piloto con estudiantes universitarios de nuevo ingreso, utilizando el instrumento traducido para asegurar su intelegibilidad. La confiabilidad del instrumento se determino mediante la intervencion de un panel de expertos quienes clasificaron las distintas posiciones dentro de cada reactivo en: realista, con merito e ingenua; se transformaron estas opciones en valores numericos lo que permitio establecer una escala Likert para cada una. Se suministro el instrumento a una muestra de estudiantes universitarios de nuevo ingreso con caracteristicas similares a las de la poblacion puertorriquena en cuanto a ejecucion en las pruebas de aptitud verbal y matematica del College Board. Los resultados de sus contestaciones fueron transformados numericamente para poder obtener el coeficiente de correlacion de Spearman-Brown para el instrumento (0.661, p < 0.01). El analisis de las contestaciones de los estudiantes refleja percepciones diversas y, en algunos casos, contradictorias con respecto al contexto de construccion del conocimiento cientifico.

  19. Teorí­as de primer y segundo orden sobre el potencial de ciertas figuras de equilibrio de cuerpos celestes

    NASA Astrophysics Data System (ADS)

    Gumbau, Manuel Forner

    2010-11-01

    Uno de los problemas que aborda la Mecánica Celeste es la determinación de las figuras de equilibrio de los cuerpos celestes. Para investigar su solución mediante métodos directos, se precisa evaluar el potencial generado por su autogravitación, el generado por su fuerza centrí­fuga y el generado por la fuerza de atracción entre los cuerpos. Los métodos clásicos de Finlay y Kopal que afrontan estos problemas, para determinar el potencial autogravitatorio en las configuraciones de equilibrio, emplean desarrollos en serie de los potenciales interior y exterior del potencial autogravitatorio. Estos métodos incurren en el error de suponer la convergencia en capas donde resulta cuestionable dicha convergencia para estos desarrollos en serie. En este trabajo se han elaborado unos algoritmos que contemplan toda la casuí&stica y que permiten una manipulación efic iente del producto de polinomios de Legendre, del producto de funciones asociada s de Legendre y del producto de armónicos esféricos como combinacióon lineal de ellos mismos, respectivamente. Se han obtenido, para primer y segundo orden en las amplitudes, los desarrollos correctos para los potencial es interior y exterior del potencial autogravitatorio para configuraciones de equilibrio aisladas, y , en primer orden de amplitudes, los mismos potenciales para los sistemas binarios próximos. Se ha elaborado un método analítico, en primer orden respecto de las amplitudes, para la determinación del potencial de marea en sistemas binarios próximos en el cual se manifiesta la forma de la componente secundaria del sistema

    Introduccion. Los trastornos del espectro autista (TEA) son trastornos del neurodesarrollo que afectan la comunicacion social y presentan conductas estereotipadas. Muestran una gran variabilidad fenotipica relacionada con la capacidad expresiva del lenguaje, habilidades cognitivas y comorbilidades psiquiatricas, entre otras. La comorbilidad psiquiatrica resulta muy frecuente en TEA y en muchos casos es multiple. La desregulacion emocional se relaciona con TEA y con otros trastornos psiquiatricos y del neurodesarrollo. La comorbilidad multiple asociada a TEA es el grupo que presenta gran incapacidad funcional, multiple farmacologia e ingresos hospitalarios. La desregulacion emocional podria ser la base de la comorbilidad multiple existente en TEA y requerira consideraciones propias en la valoracion diagnostica y tratamiento. Objetivo. Revisar la desregulacion emocional, el concepto actual y su relacion con TEA. Desarrollo. Se exponen las diferentes definiciones de desregulacion emocional, los mecanismos cognitivos y neurobiologicos asociados, la presentacion clinica cuando se asocia a TEA, su papel en la comorbilidad psiquiatrica y consideraciones en las intervenciones psicologicas y farmacologicas. Conclusiones. La desregulacion emocional podria asociarse a la comorbilidad multiple presente en personas con TEA, relacionandose con alta morbilidad, ingresos hospitalarios y uso de psicofarmacos. La falta de identificacion y diagnostico de la desregulacion emocional podria relacionarse con poca efectividad y un elevado numero de efectos secundarios cuando se trata la comorbilidad asociada a TEA.

  13. Regulando la Enfermedad a través de la Definición y la Restricción: Profesionales de la Salud Hablan sobre el VIH/SIDA1

    PubMed Central

    Rivera, Souhail Malavé; Díaz, Nelson Varas

    2009-01-01

    Resumen Las profesiones de la salud tienen un papel social dual. Por un lado, velan por el mantenimiento de la salud de la población protegiendo el bien común. Por el otro, dictaminan las formas saludables, y por lo tanto socialmente apropiadas, de ser, actuar y pensar. Este último papel, está más ligado al control social de la población que a una preocupación altruista hacia la misma. A través de esta supervisión y control, se construyen los sujetos a los cuales todos/as debemos aspirar a ser para gozar de aceptación social. Los/as profesionales de la salud han jugado un rol protagónico en dicho proceso, siendo los agentes que delimitan y definen lo que es enfermo vs. saludable, útil vs. inútil, apropiado vs. inapropiado. En el caso de la epidemia del VIH, este esfuerzo se ha hecho cada vez más vigente ya que estos/as profesionales juegan un papel importante en el tratamiento de las personas que viven con VIH/SIDA (PVVS). Sin embargo, su función está plasmada de definiciones que sirven para criminalizar a las PVVS. El objetivo de este estudio fue explorar la manera en que una muestra de profesionales de la salud en Puerto Rico construyen a las PVVS. Con este propósito, entrevistamos 80 profesionales de la salud y estudiantes de estas profesiones. Estas entrevistas fueron grabadas, transcritas y sometidas a un análisis de discurso. Los resultados reflejaron que según las personas participantes: 1) la PVVS no es una persona “normal” o funcional bajo los estándares sociales debido a que su salud no se los permite, 2) representa una carga para la sociedad incluyendo familiares, amigos/as, el mundo del trabajo, e incluso para el gobierno, 3) debe ser vigilada porque representa un riesgo para la persona seronegativa que es descrita como saludable y productiva, y 4) necesita que su salud y conducta sexual sean controladas por vía legal y/o por las personas que representan las instituciones sociales, como lo son los/as profesionales de la salud. En este artículo abordamos el potencial rol de la psicología para servir como vehículo de reconstrucción de dichas nociones, tomando en consideración su propio rol en la formación y mantenimiento de dicho sujeto socialmente deseable.

    1999-01-01

    This article draws a comparison and provides a discussion of the findings resulting from the local analyses of the 14 cities participating in the EMECAM Project. An analysis is made of the time series related to mortality, pollutants (particles in suspension, SO2, NO2, O3 and CO), temperature and other factors taken from records of public institutions. By using Poisson autoregressive regression, an estimate has been made of the short-term relationship between the number of deaths and the air pollution indicators in each one of the following cities: Barcelona, metropolitan area of Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Seville, Oviedo, Valencia, Vigo, Vitoria and Saragossa. The findings reveal the air pollution figures in our country to be similar to those of other European cities. The levels of the different pollutants point toward road traffic as being the main source of most of this pollution. A relationship has been found between the mortality and different pollutants in most cities, although the results are not homogeneous among the cities and show variability in the different causes under study. In some cities, especially in those having smaller populations, there have been no findings providing any evidence of a relationship, or the findings themselves are not highly consistent. The meta-analysis will provide estimates for all of the cities as a whole and will allow the possibility of making a more clear-cut assessment of the time lag impact of air pollution on the mortality. Worthy of special mention is the participation in this project of public health officers as actively involved researchers.

    Piatti, A. E.; Santos, J. F. C.; Clariá, J. J.; Bica, E.; Sarajedini, A.; Geisler, D.

    Washington photometry of the 5 star clusters Lindsay 32, Lindsay 38, Kron 28, Kron 44 and Lindsay 116 and their surrounding fields located towards the Small Magellanic Cloud (SMC) is presented for the first time. From the color-magnitude diagrams, cleaned from field stars contamination, the cluster and SMC field reddenings, ages and metallicities are determined. The ages - derived from the difference in the T1 magnitude betweem the giant clump and the Main Sequence turnoff point - vary between 2 and 6 Gyr, and the metallicities ([Fe/H]) between -1.65 and -1.10. Lindsay 116 is located closer to the Large Magellanic Cloud (LMC) than to the SMC and its fundamental parameters suggests a higher probability of belonging to the LMC. The results obtained in this work, combined with previous estimates of age and metallicity for other seven clusters, allow us to draw the following conclusions: (1) There does not exist an age-position relation in the SMC, but a age-metallicity one. (2) The chemical enrichment in the SMC has been very efficient during the last 5 Gyr. (3) The SMC clusters formation and evolution can be better represented by a bursting star formation process than by a continuum star formation mechanism.

    2010-09-01

    This study sought to evaluate second-generation drug-eluting stent (DES) thrombosis in clinical practice. First-generation DES are associated with a significant incidence of late thrombosis. There is paucity of data regarding real practice late thrombosis incidence and predictors with second-generation DES, zotarolimus-eluting stent (ZES), and everolimus-eluting stents (EES). A prospective, large-scale, non-industry-linked multicenter registry was designed. Complete clinical-procedural data and systematic follow-up of all patients treated with these stents was reported in a dedicated registry supported by the Spanish Working Group on Interventional Cardiology. From 2005 to 2008, 4,768 patients were included in 34 centers: 2,549 treated with ZES, and 2,219 with EES. The cumulative incidence of definite/probable thrombosis for ZES was 1.3% at 1 year and 1.7% at 2 years and for EES 1.4% at 1 year and 1.7% at 2 years (p = 0.8). The increment of definite thrombosis between the first and second year was 0.2% and 0.25%, respectively. In a propensity score analysis, the incidence remained very similar. Ejection fraction (adjusted hazard ratio [HR]: 0.97; 95% confidence interval [CI]: 0.95 to -0.99; p = 0.008), stent diameter (adjusted HR: 0.37; 95% CI: 0.17to 0.81; p = 0.01) and bifurcations (adjusted HR: 2.1; 95% CI: 1.14 to 3.7; p = 0.02) emerged as independent predictors of thrombosis. In the subgroup of patients with bifurcations, the use of ZES was independently associated with a higher thrombosis rate (adjusted HR: 4; 95% CI: 1.1 to 13; p = 0.03). In a real practice setting, the incidence of thrombosis at 2 years with ZES and EES was low and quite similar. The incidence of very late thrombosis resulted lower than was reported in registries of first-generation DES. In the subset of bifurcations, the use of ZES significantly increased the risk of thrombosis. Copyright © 2010 American College of Cardiology Foundation. Published by Elsevier Inc.

    Chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) are highly prevalent chronic diseases, which represent an important public health problem and require a multidisciplinary management. T2DM is the main cause of CKD and it also causes a significant comorbidity with regard to non-diabetic nephropathy. Patients with diabetes and kidney disease represent a special risk group as they have higher morbi-mortality as well as higher risk of hypoglycemia than diabetic individuals with a normal kidney function. Treatment of T2DM in patients with CKD is controversial because of the scarcity of available evidence. The current consensus report aims to ease the appropriate selection and dosage of antidiabetic treatments as well as the establishment of safety objectives of glycemic control in patients with CKD.

    We relate in this article a didactic experience studying the moon phases with a group of middle school students of a private school of the municipality of Passo Fundo, RS. Based on David Ausubel's Meaningful Learning Theory, we have sought to develop a proposal following a didactic model which simulates the phases of the Moon, as based on the previous conceptions of the students. The signs of learning were evidenced by means of memory registries of the activity. From the obtained results we believe that the proposal achieved its goals, since the students were able to identify, differentiate and transfer the phenomenon of the moon phases to new contexts. Thus, it is concluded that a methodology focused on a meaningful content for the students is fundamental to the construction and genuine grasping of what is being learned. Neste artigo, relata-se uma experiência didática de estudo das fases da Lua com uma turma do 6° ano do Ensino Fundamental, de uma escola privada do município de Passo Fundo, RS. Tendo como fundamentação teórica a Teoria da Aprendizagem Significativa de David Ausubel, buscou-se desenvolver a proposta a partir de um modelo didático que simula as fases da Lua e com base nas concepções prévias dos estudantes. Os indícios da aprendizagem foram constatados através de registros de memórias da atividade. Pelos resultados apresentados, acredita-se que a proposta alcançou seus objetivos, uma vez que os estudantes conseguiram identificar, diferenciar e transferir o fenômeno das fases da Lua para novos contextos. Assim, conclui-se que uma metodologia com enfoque em um conteúdo significativo ao estudante é fundamental para a construção e compreensão genuína do que está sendo aprendido.

    We occasionally include projects in our learner-centered introductory astronomy college course to enable non-science major students explore some astronomical concepts in more detail than otherwise. Such projects also highlight ongoing or upcoming astronomical events. We hope that students will feel more interested in astronomy through projects tied to astronomical events. In Spring 2012, we offered short essays focused on eclipses, transits and occultations to promote the rare transit of Venus that occurred on June 5th, 2012. We asked students to write two short essays from three that were offered. The essays contained descriptive and conceptual parts. They were meant to serve as teaching tools. 62% of 106 essays from 55 students earned A, B or C grades. 21% of 47 feedback survey respondents felt the essays increased their interest in astronomy. 49% of respondents felt that the essays were not educationally beneficial and should not be offered again. The most common written response to our survey indicated that students need more guidance and better preparation in writing successful essays. Since students found the conceptual parts of the essays difficult, in the future we will provide relevant activities prior to essay deadlines to help students create successful essays. Ocasionalmente, incluimos proyectos en nuestro curso de introducción a la astronomía universitario centrado en el alumno para permitir que los estudiantes de carreras no científicas exploren algunos conceptos astronómicos en más detalle que lo habitual. Estos proyectos también ponen en relevancia eventos astronómicos en curso o futuros. Esperamos que los estudiantes se sientan más interesados en la astronomía a través de proyectos vinculados a eventos astronómicos. En el período de primavera de 2012 (EUA), propusimos breves ensayos centrados en los eclipses, tránsitos y ocultaciones para promover el raro tránsito de Venus que se produjo el 5 de junio de 2012. Le pedimos a los estudiantes que escribieran dos ensayos cortos de tres que se proponían. Los ensayos contenían partes descriptivas y conceptuales. Los mismos estaban destinados a servir como herramientas de enseñanza. 62% de los 106 ensayos de 55 estudiantes obtuvo grados A, B o C. 21% de los 47 encuestados que respondieron al cuestionario posterior consideró que los ensayos aumentaron su interés por la astronomía. 49% de los encuestados consideró que los ensayos no eran educacionalmente útiles y que no deben ser propuestos de nuevo. Las respuestas escritas más comunes a nuestra encuesta indicaran que los estudiantes necesitan más orientación y una mejor preparación en la redacción de ensayos exitosos. Dado que los estudiantes encontraron las piezas conceptuales de los ensayos difíciles, en el futuro vamos a ofrecer actividades pertinentes antes de los plazos de redacción para ayudar a los estudiantes a crear ensayos de mayor calidad. Nós ocasionalmente incluímos projetos em nosso curso universitário introdutório centrado no aluno para permitir aos estudantes que pertencem às carreiras não científicas explorar alguns conceitos astronômicos em mais detalhes do que o normal. Tais projetos também enfatizam eventos astronômicos em curso ou futuros. Esperamos que os alunos se sintam mais interessados na astronomia através de projetos ligados a eventos astronômicos. No termo de Primavera de 2012 (EUA), propomos ensaios curtos focados em eclipses, trânsitos e ocultações para promover o raro trânsito de Vênus que ocorreu no dia 5 de junho de 2012. Pedimos aos alunos que escrevessem dois ensaios curtos dentre três que foram propostos. Os ensaios continham partes descritivas e conceituais. Eles foram feitos para servir como ferramentas de ensino. 62% de 106 ensaios de 55 alunos ganhou graus A, B ou C. 21% dos 47 entrevistados que responderam ao levantamento posterior sentiu que os ensaios aumentaram seu interesse na astronomia. 49% dos inquiridos consideraram que os ensaios não eram benéficos para a educação e que não devem ser propostos novamente. As respostas escritas mais comuns da nossa pesquisa indicaram que os alunos precisam de mais orientação e melhor preparação para escrever ensaios bem sucedidos. Como os alunos consideraram difíceis os aspectos conceituais dos ensaios, no futuro iremos fornecer atividades relevantes antes dos ensaios para ajudar os alunos a escrevê-los com sucesso.

Los análisis de los modelos de ecuaciones estructurales confirmaron las hipótesis. Sin embargo, los tres efectos directos de los conflictos en la internalización de los problemas, agresión y comportamiento anormal seguían siendo significativos. Además, se identificó un efecto mayor del rol paternal en comparación con el rol maternal en la relación entre conflicto y la creencia filial reciproca atenuada y entre la amenaza percibida y la internalización de los problemas. Se discuten las implicaciones para la comprensión del proceso mediador responsable de todos los efectos indirectos, incluso los subsidiarios, y el mayor impacto del conflicto con los padres que con las madres. Igualmente, se discuten las limitaciones del estudio y las consideraciones para la investigación futura.

    The aim of this study is to Mortality show the protocol of analysis which was set out as part of the EMECAM Project, illustrating the application thereof to the effect of pollution has on the mortality in the city of Valencia. The response variables considered will be the daily deaths rate resulting from all causes, except external ones. The explicative variables are the daily series of different pollutants (black smoke, SO2, NO2, CO, O3). As possible confusion variables, weather factors, structural factors and weekly cases of flu are taken into account. A Poisson regression model is built up for each one of the four deaths series in two stages. In the first stage, a baseline model is fitted using the possible confusion variables. In the second stage, the pollution variables or the time legs thereof are included, controlling the residual autocorrelation by including mortality time lags. The process of fitting the baseline model is as follows: 1) Include the significant sinusoidal terms up to the sixth order. 2) Include the significant temperature or temperature squared terms with the time lags thereof up to the 7th order. 3) Repeat this process with the relative humidity. 4) Add in the significant terms of calendar years, daily tendency and tendency squared. 5) The days of the week as dummy variables are always included in the model. 6) Include the holidays and the significant time lags of up to two weeks of flu. Following the reassessment of the model, each one of the pollutants and the time lags thereof up to the fifth order are proven out. The impact is analyzed by six-month periods, including interaction terms.

    As part of the EMECAM Project, the objective of this study is that of assessing the impact of air pollution on the daily mortality in Seville throughout the 1992-1996 period. During the 1992-1996 period, readings were taken daily of the amounts of SO2, particles in suspension (PM10) and NO2 present in the air in the city of Seville, in addition to the number of deaths daily due to different causes. For analyzing this data, a multivariable Poisson regression model was used for modeling each one of the causes of death in terms of the air immission readings, controlling other confusion-causing variables. A relationship was found to exist between the rises in the NO2 levels and the daily death rate throughout the months of May to October. For each 10 micrograms/m3 rise, the risk of death or all causes showed a 2% rise, the same rise in the NO2 levels leading to a 3% rise in the risk of death resulting from cardiovascular diseases. A relationship exists between the levels of NO2 air pollution and the daily death rate in Seville. The findings provide scientific knowledge and information which can be of use for preventing the impact of air pollution on human health.

    The objective of this article is that of assessing the short-term relationship between the black smoke (SM) and SO2 levels and the mortality in Vitoria-Gasteiz over a five-year period by means of employing the procedure for analysis standardized in the EMECAM Project. Ecological time series study aimed at estimating the relationship between the daily fluctuations in the mortality (total mortality of all ages and total death rate for those over age 70) and air pollution (sulfur dioxide-SO2 and black smoke), employing the Poisson regression models. The EMECAM methodology was followed. The median of daily deaths was three for the entire population and two for the elderly. The mean black smoke level was 51.15 micrograms/m3 and that of SO2 18.04 micrograms/m3. A statistically significant relationship was found to exist between black smoke and the mortality for the elderly through the cold half of the year, with an RR of 1.014 (CI95%: 1.002-1.026), pertinent to a 10 micrograms/m3 rise in the pollutant. A threshold at 80-90 micrograms/m3 seemed to be detected for black smoke. The relationship with SO2 was not significant. The black smoke levels for the period studied are related to a rise in the mortality among the elderly, tallying with the results of other studies.

    To assess the short-term impact of pollution on the respiratory death rate in the city of Saragossa throughout the 1991-1995 period and to pinpoint whether any differences exists in terms of age and time of the year. The relationship of daily concentrations of smog and SO2 to the daily deaths due to respiratory diseases (CIE-9 460-486) and chronic lung blockage disease and similar EPOC-EA (490-496) was analyzed using Poisson models in keeping with the EMECAM procedure. Possible differences in the impact on those below and over age 70 and according to the six-month period in question were researched. Relative risks (RR) and 95% confidence, intervals (CI95%) WERE CALCULATED FOR 10 micrograms/m3 rises in pollutant. A relationship was found to exist between the respiratory and smog death rate (RR 1.028 CI95% 1.006-1051), the highest risk being during the six-months period of warm weather. For those individuals over age 70, the relationship remained the same throughout this six-month period and was negative for those individuals under age 70. The RR's for the death rate based on EPOC-EA were, overall, 1.038 (CI95% 1.002-1075) and of 1.068 (CI95%: 1.004-1.137) for the six-month period of warm weather. The SO2 pollution showed a positive relationship to the respiratory death rate for the warm period for all ages, RR 1.093 (CI95%: 1.006-1.187) and for those under age 70 (RR 1.240 CI95%: 1.028-1.496). The impact was not conclusive for the cases of pneumonia. Low levels of air pollution can have a significant impact on the respiratory death rate, especially among the elderly and during the six-month period of warm weather.

    To assess the short-term impact of air pollution on the daily death rate in the city of Pamplona. Ecological study with a population of 212,000 inhabitants. A time series data analysis is conducted by means of multiple linear regression and Poisson regression, with the daily death rate data, air pollution levels for Particles and SO2, weather parameters of average relative humidity and temperature daily and number of cases weekly of flu for the 1991-1995 period. The average number of deaths daily for non-external causes is that of 4.15 deaths, with a range from zero to 13 deaths. The city of Pamplona has a mean annual temperature of 12.7 degrees C (-2.3 degrees C to 31.6 degrees C) and a relative humidity of 68.5%. In the model, the temperature (with a one-day time lag and a six-day time lag temperature squared) and the humidity (with a one-day time lag) is related to the death rate for all causes. But the death rate for non-external causes is only related in the model with the temperature (one-day time lag, P: 0.035) and five-day time lag with temperature squared (p: 0.028). The timely estimates of the relative particle-related risk show that the highest risk of dying stems from respiratory causes with a relative risk of 1.13. However, none of these relationships is statistically significant. In the case of Sulfur Dioxide, the estimates closely near the zero figure, and none of them is significant. The Temperature has an impact of the death rate for all causes, both external and non-external, and the relative humidity solely has an impact on the death rate for non-external causes. It has not been possible to prove any influence of the daily environmental pollution levels on the daily death rate.

    The studies conducted to date regarding the possibility that air pollutants, at levels considered safe to date, are capable of having impact are capable of having impact on human health have not led to homogeneous findings. This study is aimed at estimating the degrees of relationship between the daily levels of the pollutants and the death rate on a short-terms basis in the two most populated cities in Austria (Gijón and Oviedo), as well as contributing to increasing the statistical importance and the representative nature of the EMECAM Project, within which this study is comprised. Ecological time series study, Estimate of degrees of group exposure based on the readings taken at the pollution control stations. Modeling of the death rate series, including control variables, by means of Poisson regression. Estimating risks related to each pollutant for the death rate, controlling the series-based autocorrelation. Throughout the 1993-1996 period, the pollution by means of particles in suspension and CO was greater in Gijón, that involving SO2 and NO2 having been greater in Oviedo. In these two cities, the levels can be considered to be low and to fall within what is considered admissible under the laws currently in impact. Most of the relative risk forecasts neared the zero impact point, although significant positive (especially for NO2) as well as negative relationships have been found to exist. The significant relationships found were not proven to be consistent in these two cities for the periods studied. Based on the findings of this study, the conclusion cannot be drawn that a clear-cut relationship exists between the pollutants studied (particles, SO2, NO2, CO) and the death rate on a short-term basis, at least at the levels detected in Gijón and Oviedo.

    The objective of this study was to assess the short-term impact of air pollution with sulfur dioxide (SO2), total suspended particles (TSP), nitrogen dioxide (NO2) and black smoke (BS) on the daily number of deaths in the metropolitan area of Bilbao. The EMECAM project protocol was followed. Increases in TSP, in both maximum hourly figures and daily averages, are significantly associated with increases in the daily number of deaths from all causes, from circulatory causes and from all causes among those older than 70. No differences between six-month periods were found. NO2 average levels were associated with daily mortality from respiratory causes in the entire period and during the warm season, and from all causes among those older than 70 in the cool months. TSP levels are associated with daily mortality in the metropolitan area of Bilbao. The relationship between NO2 and the number of deaths from respiratory causes, very high in the warm season, needs further research to assess its independence.

    Most of the studies which demonstrate the existence of a short-term relationship between air pollution and morbidity and the Mortality analyze the impact of "classic" pollutants which are by-products of combustion. However, the changes in the sources of these emissions, shifting basically toward road traffic, has made a change in air pollution, heightening the importance of the photochemical components, such as ozone (O3) and nitrogen dioxide (NO2). Barcelona is a city located in a mild climate zone, and its air pollution comes mainly from vehicle emissions. The main objective of this article is that of analyzing the relationship between the photochemical pollutants, NO2 and O3 and the death rate for different causes in the city of Barcelona throughout the 1991-1995 period, using the procedure for analysis set out as part of the EMECAM Project. Daily changes in the number of deaths resulting from all causes, of the number of deaths for all causes of those over age 70, of the number of deaths resulting from cardiovascular diseases, and of the number of deaths resulting from respiratory-related causes are related to the daily changes in the photochemical pollutants using autoregressive Poisson models, controlling confusion-causing variables such as the temperature, the relative humidity, the systematic time structure and the autoregressive structure. Except for the relationship between O3 and the mortality for causes involving respiratory diseases, the relationships between photochemical pollutants and the mortality for all the causes considered were statistically significant. The risks related to dying as a result of rises in O3 were greater than as a result of rises in NO2, almost triple among cardiovascular diseases. The risks related to dying for all the causes are lower than for specific causes and than for those individuals over age 70. The results of the analysis by six-month periods are quite similar to the overall results, revealing, in any event, relative risks somewhat greater during the warm months (May to October). Photochemical pollution, especially that which is caused by O3, comprises a health risk. In the case of NO2, this might not be more than an indicators of the suspended particles or of other pollutants stemming from city traffic. There may be a certain adjustment between six-month periods of the impact of O3 on the mortality for causes of the circulatory system.

    The objective of this study was to estimate the relationship between the levels of air pollution and the daily mortality in the city of Huelva for the 1993-1996 period using the EMECAM methodology. The number of daily deaths for all causes except external ones, the death rate of those over age 69, due to diseases of the circulatory system and for respiratory diseases were used as rate indicators. Four pollutants--SO2, PM10, NO2 and CO--were analyzed, the daily levels of which were furnished by the air pollution monitoring network in Huelva. Autoregressive Poisson regression models were constructed controlling by tendency, seasonality, temperature, humidity, flue and events out of the ordinary. For the mortality rate for all causes, a significant association impact was found to exist for the NO2 for the entire period (RR10 microgram/m3: 1.0414; CI95%: 1.0047-1.0794) and for the particles (PM10) for the cold half of the year (RR10 microgram/m3: 1.0358; CI95%: 1.007-1.0722). For the mortality in people over age 69, a significant relationship was found to exist for SO2 throughout the entire period (RR10 microgram/m3: 1.0606; CI95%: 1.0020-1.1227). A significant relationship to the mortality from respiratory disease particles (PM10) was found to exist for the cold half of the year (RR10 microgram/m3: 1.1412; IC95%: 1.0300-1.2644). There was no association of contaminants with cardiovascular mortality; also there was no association between levels of CO and mortality indicators. In Huelva, significant relationships have been found to exist between the current levels of air pollution resulting from particles, SO2 and NO2 and the daily mortality. The impact of these pollutants on the mortality is coherent with scientific literature, although in the case of Huelva, the extremely small number of daily deaths due to its small population and other factors limit the consistency thereof.

    The problems of air pollution became noticeable in Cartagena in the seventies, high SO2 and particle levels having been reached from time to time. Our aim is to assess, using the EMECAM methodology, the acute impact of SO2 and particle air pollution on the daily death rate of the city of Cartagena in the 1992-1996 period. A daily listing is provided of the total number of non-accidental deaths within the population as a whole and for those over age 70, the cardiovascular and the respiratory deaths due to dioxide and particle air pollution for the 1992-1996 period using autoregressive Poisson models which control seasonality, weather, time of year, flu, special events, and time lags. In the period under study, there has been a drop in the SO2 air pollution as compared to previous years, which was not as marked for the particles. The analyses reveal significant relationships in the total non-accidental deaths in those over age 69, with the average particle count and those particles with cardiovascular deaths for the months of May to October. In the six-month period of the year, when the weather is cold, we found a positive statistically significant relationship to exist in the maximum daily hourly value of the particles and the deaths due to cardiocirculatory and respiratory diseases. However, there is no consistency in the between on assessing the reliability of the models.

    In the last decade several studies have found out an association between air pollution and mortality in levels below the standards allowed by regulations. Castellón is a small city (134,000 inhabitants) with low air pollution levels. This work aims to identify if there is a short term relation between these both variables in this city. We used mortality data and air pollution data (black smoke and sulphur dioxide), from 1.991 to 1.995, doing an ecological study using a time series analysis with the day as unit of the analysis. Poisson regression allow us to get the relative risk adjusted by others variables (meteorological, trend, influenza, day of the week, season) in autoregresive models. Black smoke and SO2 daily means were respectively 34.6 and 15.7 micrograms/m3. Results showed a 3.6% (IC95 0.3-7.0) of SO2 and 3.5% (IC95% 0.5-6.5) increment of cardiovascular mortality for an increment of 10 micrograms/m3 of SO2 and black smoke respectively. Sulphur dioxide was positively associated with all four groups of mortality causes but only in cold season. Even in a small city with low air pollution levels, we found an association between air pollution and immediate mortality. In some cases, the analysis by periods (warm and cold) show an strong effect modification.

    In the Autonomous Region of Galicia, no study has been made of the impacts of air pollution on human health, despite the fact that several of its major cities have moderate levels of pollution. Therefore, we have considered the need of making this study in the city of Vigo. The main objective of this analysis is that of analyzing the short-term impact of air pollution on the daily death rate for all reasons in the city of Vigo throughout the 1991-1994 period, by using the procedure for analysis set out as part of the EMECAM Project. The daily fluctuations in the number of deaths for all causes with the exception of the external ones are listed with the daily fluctuations of sulfur dioxide and particles using Poisson regression models. A non-parametric model is also used in order to better control the confusion variables. Using the Poisson regression model, no significant relationships have been found to exist between the pollutants and the death rate. In the non-parametric model, a relationship was found between the concentration of particles on the day immediately prior to the date of death and the death rate, an effect which remains unchanged on including the autoregressive terms. Particle-based air pollution is a health risk despite the average levels of this pollutant falling within the air quality guideline levels in the city of Vigo.

    To determine the short-term impact of air pollution on mortality in the city of Valencia throughout the 1994-1996 period by employing the analysis method of the Spanish multicenter study with regard to the relationship between air pollution and the mortality (EMECAM Project). The daily levels of black smoke, sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3) were obtained from the Valencia air pollution monitoring network. The death rate indicators analyzed were the daily number of death due to all causes, except the external ones, the deaths of those over age 70, and the deaths resulting from respiratory and cardiovascular diseases. Following the methods of the EMECAM Project, autoregressive Poison regression models were built up, controlling the different confounding factors (seasonality, trend, calendar, weather variables and flu impact). For total mortality except the external ones, a significant impact of black smoke (RR 10 micrograms/m3: 1.013; CI95% 1.003 to 1.023) and for CO 24 la (RR 1 mg/m3: 1.024; CI95% 1.003 to 1.046) was found. For the mortality of those individuals over 70, the estimated impact was somewhat greater than for black smoke (RR 10 micrograms/m3: 1.017; CI95% 1.005-1.029), as well as for CO2 1 h (RR 10 micrograms/m3: 1.007; CI95% 1.001-1.013). No significant relationship was found with the mortality due to respiratory or cardiovascular diseases for the entire period. The current levels of pollution in the city of Valencia show a significant impact on daily mortality. These findings are consistent with the previous research and are coherent with those obtained on analyzing the relationship between air pollution and morbidity indicators.

    Despite the changes which have taken place in the sources of emissions, the levels of particles, SO2 and CO continue to be high in the municipality of Madrid. Apart from this, photochemical pollutants, such as NO2 and O3 are taking on growing importance due to the increased number of cars and trucks on the road and the major degrees of sunlight in this city. The objective of this article is to set out the short-term relationship between the major pollutants and the daily death rate in the city of Madrid for the 1992-1995 period, using the standardized procedure of the EMECAM Projects (Spanish Multicenter Study of Air Pollution and Death Rate). The daily fluctuations in the death rate for all causes except external ones for all ages and for those individuals over age 69, in addition to those of the circulatory system and respiratory apparatus are related to the daily fluctuations in particles (PM10), SO2, NO2, CO and O3, by means of autoregressive Poisson regression models. The seasonality, tendency, temperature, relative humidity, flu, day of the week, holidays and events out of the ordinary are controlled. Statistically significant positive relationships were found to exist between SO2 and all of the death rate series analyzed, between CO and the death rate of individuals over age 69, as well as with cardiovascular and respiratory deaths and of the particles to the death rate as the result of cardiovascular disease. A statistically significant relationship was also found to exist between NO2 and the cardiovascular death rate. These impact are immediate, that is to say, they occur with the pollutants of the same day. No significant positive relationships were found to exist for O3. These findings suggest that, for a broad spectrum of major pollutants, the current levels of air pollution in Madrid are related to a rise in the death rate.

    Observações de Supernovas do tipo Ia mostram que a expansão do Universo está acelerando. Segundo as equações de Einstein uma componente com pressão negativa (energia escura) é necessária para explicar a aceleração cósmica. Além da energia escura é usualmente admitido que no Universo há também uma matéria exótica com pressão zero, que é chamada de matéria escura. Essa componente possui um papel fundamental na formação de estruturas no Universo. Recentemente tem se explorado a possibilidade de que matéria e energia escura poderiam ser unificadas através de uma única componente, que tem sido denominada de quartessência. Um exemplo de fluido com essas características é o Gás de Chaplygin Generalizado, que possui uma equação de estado da forma p = -A/ra. Inicialmente consideramos o caso especial a = 1 (gás de Chaplygin) e vinculamos parâmetros do modelo utilizando observações em raios-X do satélite Chandra da fração de massa de gás em aglomerados de galáxias. Uma comparação dos vínculos obtidos com esse teste com outros testes, tais como supernovas e idade do Universo, mostra que esse teste é bastante restritivo. Exibiremos ainda resultados para o caso em que a curvatura é nula e o parâmetro a está compreendido no intervalo -1 < a 1.

    Resumen Introducción La encefalitis por anticuerpos contra el receptor de NMDA (NMDAR) suele desarrollarse como un síndrome característico de evolución multifásica y diagnóstico diferencial amplio. Pacientes Presentamos a 2 pacientes diagnosticadas de encefalitis por anticuerpos NMDAR con un cuadro clínico típico, pero que inicialmente señaló otras etiologías. Discusión La afectación frecuente de pacientes jóvenes con manifestaciones psiquiátricas prominentes indica frecuentemente otras consideraciones diagnósticas; las más frecuentes son las encefalitis virales, los procesos psiquiátricos y el síndrome neuroléptico maligno. Varios síndromes previamente definidos de manera parcial o descriptiva en adultos y pacientes pediátricos probablemente eran casos de encefalitis anti-NMDAR. Conclusiones La encefalitis anti-NMDAR debe considerarse en pacientes jóvenes con manifestaciones psiquiátricas subagudas, movimientos anormales y alteraciones autonómicas. La caracterización clínica e inmunológica de esta enfermedad ha llevado a la identificación de nuevos anticuerpos que afectan a procesos de memoria, aprendizaje, conducta y psicosis. PMID:20964986

    Background The adipokine leptin realizes signal transduction via four different membrane-anchored leptin receptor (Ob-R) isoforms in humans. However, the amount of functionally active Ob-R is affected by constitutive shedding of the extracellular domain via a so far unknown mechanism. The product of the cleavage process the so-called soluble leptin receptor (sOb-R) is the main binding protein for leptin in human blood and modulates its bioavailability. sOb-R levels are differentially regulated in metabolic disorders like type 1 diabetes mellitus or obesity and can, therefore, enhance or reduce leptin sensitivity. Methodology/Principal Findings To describe mechanisms of Ob-R cleavage and to investigate the functional significance of differential sOb-R levels we established a model of HEK293 cells transiently transfected with different human Ob-R isoforms. Using siRNA knockdown experiments we identified ADAM10 (A Disintegrin And Metalloproteinase 10) as a major protease for constitutive and activated Ob-R cleavage. Additionally, the induction of lipotoxicity and apoptosis led to enhanced shedding shown by increased levels of the soluble leptin receptor (sOb-R) in cell supernatants. Conversely, high leptin concentrations and ER stress reduced sOb-R levels. Decreased amounts of sOb-R due to ER stress were accompanied by impaired leptin signaling and reduced leptin binding. Conclusions Lipotoxicity and apoptosis increased Ob-R cleavage via ADAM10-dependent mechanisms. In contrast high leptin levels and ER stress led to reduced sOb-R levels. While increased sOb-R concentrations seem to directly block leptin action, reduced amounts of sOb-R may reflect decreased membrane expression of Ob-R. These findings could explain changes of leptin sensitivity which are associated with variations of serum sOb-R levels in metabolic diseases. PMID:22545089

    RESUMEN La comunicación sobre sexualidad entre padres/madres y adolescentes enfrenta dificultades particulares producto de factores socioculturales. Este estudio tuvo como objetivo documentar las actitudes de padres/madres y adolescentes hacia la comunicación sobre temas de sexualidad. Los resultados emanan de la medición inicial del Proyecto Cuídalos. Los datos de este estudio forman parte de un estudio amplio que evaluó un módulo interactivo basado en la web para mejorar comunicación sobre temas de salud entre padres/madres y adolescentes entre 13–17 años. En este artículo, reportamos datos basales que contestaron los/as participantes sobre comodidad al hablar sobre temas de salud sexual. La muestra, de los datos aquí expuestos, estuvo compuesta por 458 diadas de madres/padres y sus hijos/as adolescentes (n=916). Se realizó análisis de frecuencias y medidas de tendencia central con los datos obtenidos inicialmente. La edad promedio de los adolescentes fue de 15 años, de los que un 15% se encontraban activos sexualmente. Los/as adolescentes tienen mejor disposición que los/as padres/madres para hablar sobre sexualidad. Sin embargo, los/as padres/madres entienden que comparten suficiente información sobre temas relacionados a la sexualidad. Los/as padres/madres y adolescentes reportaron algún grado de dificultad e incomodidad al hablar sobre métodos específicos de prevención. Los resultados destacan la necesidad de incorporar a los/as padres/madres en intervenciones con adolescentes sobre temas de salud sexual. En Puerto Rico es necesario desarrollar programas dirigidos a minimizar las conductas sexuales de alto riesgo en jóvenes. PMID:28736599

    Objetivos: Identificar oportunidades de mejora, sobre el conocimiento disponible del personal sanitario (en concreto a personal médico, farmacéutico y de enfermería), sobre reacciones alérgicas cruzadas (RAC) de penicilinas y AINEs. Método: Estudio prospectivo cuasiexperimental pre-exposición en un hospital de 412 camas. Se realizó una valoración del conocimiento sobre RAC de penicilinas y AINEs, a través de encuestas anónimas, antes (1a encuesta) y después (2a encuesta) de la implantación de una serie de medidas de mejora: protocolo “paciente alérgico a medicamentos”, tarjeta de bolsillo, póster resumen de información y charlas divulgativas. Las propias encuestas sirvieron de hoja de recogida de datos y el análisis estadístico se llevó a cabo con el programa SPSS v18.0. Resultados: La media de errores en las 1as encuestas sobre “RAC en paciente alérgico a penicilinas” y sobre “RAC en paciente alérgico a AINEs”, fue de 20,53 y 27,62, respectivamente. La media de errores en las 2as encuestas sobre “RAC en paciente alérgico a penicilinas” y sobre “RAC en paciente alérgico a AINEs”, fue de 2,27 y 7,26, respectivamente. Todos los resultados se consideraron significativos para un nivel 945;< 0,05. Conclusiones: - No se dispone de un nivel adecuado de conocimiento sobre RAC de penicilinas y AINEs, lo que justifica la realización de un ciclo de mejora. - Tras la implantación de las medidas de mejora se aprecia un aumento en el nivel de conocimiento sobre RAC en penicilinas y AINEs, en los grupos de estudio.

    Antecedentes: El nacimiento pretérmino es una emergencia nutricional y requiere consideraciones especiales. Objetivos: Se propuso evaluar el aporte de leche humana (LH) en el recién nacido prematuro hospitalizado de bajo peso (RNP-BP) y muy bajo peso (RNP-MBP), factores maternos y su relación con parámetros nutricionales. Materiales y métodos: Participaron 87 RNP-BP y 82 RNP-MBP admitidos en un hospital público en Córdoba, Argentina. Se registró la antropometría evolutiva, alimentación, parámetros bioquímicos, antecedentes del niño y maternos. Se calculó el aporte de LH. Se analizaron los valores antropométricos y bioquímicos, días de internación y factores maternos según aporte de LH. Resultados: El 36,36% de los RNP-MBP y el 31,02% de los RNP-BP cubrió más del 20% de su alimentación con LH. La hemoglobina sérica fue superior en RNP-MBP que recibieron más LH (p=0,01). Los RNP con menos del 20% de su alimentación con LH presentaron una asociación estadísticamente significativa entre la cantidad de LH y la talla al alta hospitalaria. Se observó una elevada prevalencia de cesáreas, asociada a un menor aporte de LH. Conclusiones: El aporte de LH contribuiría a estabilizar la hemoglobina en RNP. La presencia de cesárea podría asociarse a un menor aporte de LH a los RNP.

  18. Leptin as well as Free Leptin Receptor Is Associated with Polycystic Ovary Syndrome in Young Women

    PubMed Central

    Rizk, Nasser M.; Sharif, Elham

    2015-01-01

    Background and Aim. Leptin has two forms in the circulation: free and bound forms. The soluble leptin receptor (sOB-R) circulates in the blood and can bind to leptin. The aim of this study is to assess the concentrations of the leptin and the sOB-R in PCOS and its relation to adiposity, insulin resistance, and androgens. Methods. A cross-sectional study included 78 female students aged 17–25 years. Fasting serum leptin and sOB-R concentrations were measured. The anthropometric variables and the hormonal profile such as insulin, female and male sex hormones, and prolactin were assessed. Results. In PCOS, leptin level (ng/ml) and free leptin index (FLI) increased significantly while sOB-R (ng/ml) significantly decreased compared to control subjects. In age-matched subjects, obese PCOS had increased leptin level in ng/ml (median level with interquartile levels) of 45.67 (41.98–48.04) and decreased sOB-R in ng/ml 11.47 (7.59–16.44) compared to lean PCOS 16.97 (10.60–45.55) for leptin and 16.62 (11.61–17.96) for sOB-R with p values 0.013 and 0.042, respectively. However, body mass index (BMI) is significantly correlated with leptin and s-OBR, while no significant correlations with parameters of insulin resistance were detected. Conclusion. PCOS is associated with hyperleptinemia and increased free leptin index. Decreased sOB-R could be a compensatory mechanism for the defective action of leptin. PMID:26180527

    There are limited data on fetuin-A, soluble leptin receptor (sOB-R) and free leptin index (FLI) in patients with chronic lymphocytic leukemia (CLL). The aim of this study was to compare circulating fetuin-A, sOB-R levels and FLI between 95 patients with CLL and 95 matched controls, as well as among different stages of CLL. Circulating fetuin-A was significantly lower in cases than controls (241.9 ± 99.2 vs. 288.8 ± 127.7 μg/mL; p = 0.005). Although circulating sOB-R levels were similar between groups, FLI was lower in cases than controls (0.45 ± 0.42 vs. 0.67 ± 0.57; p = 0.003). Furthermore, lower fetuin-A or FLI, but not sOB-R, were independently associated with CLL (p < 0.05), particularly among overweight/obese individuals. Fetuin-A, s-OB-R and FLI were similar between different stages of CLL severity, or between symptomatic and asymptomatic disease. In conclusion, circulating fetuin-A and FLI, but not sOB-R, were lower in patients with CLL than controls, a finding warranting further investigation.

    Little is known regarding the associations between high-molecular-weight (HMW-) adiponectin, leptin and soluble leptin receptor (sOB-R) and metabolic syndrome (MetS) in Chinese. Also few studies elucidate the effects of inflammation and body fat mass on the relations. Plasma HMW-adiponectin, leptin and sOB-R were measured among 1055 Chinese men and women (35∼54 yrs). Whole body and trunk fat mass were determined by Dual-energy X-ray absorptiometry. MetS was defined by the updated NCEP/ATPIII criterion for Asian-Americans. HMW-adiponectin was inversely associated with MetS in multivariate model including fat mass index (FMI), inflammatory markers, leptin and sOB-R (OR in the highest quartile= 0.30, 95%CI 0.18∼0.50, P<.0001). Plasma sOB-R was also inversely associated with MetS independent of body fatness and inflammatory markers, whereas the association was somewhat attenuated after adjusting HMW-adiponectin (OR for the highest quartile = 0.78, 95%CI 0.47∼1.32, P = 0.15). In contrast, leptin was associated with increased odds of MetS independent of inflammatory markers, HMW-adiponectin, and sOB-R (OR for the highest quartile= 2.64, 95%CI 1.35∼5.18, P = 0.006), although further adjustment for FMI abolished this association. HMW-adiponectin exhibited strong inverse associations with MetS independent of body composition, inflammation, leptin and sOB-R; while the associations of leptin and sOB-R were largely explained by fat mass or HMW-adiponectin, respectively.

    Introducción: actualmente, el uso de Internet como fuente de información sobre temas de salud, y más concretamente sobre trastornos alimentarios, está aumentando enormemente. Sin embargo, al no existir una regulación precisa, la información disponible puede variar en calidad y fiabilidad. Objectivo: el objetivo del presente trabajo fue determinar tanto la calidad general como la información contenida en las páginas web sobre obesidad y trastornos de la alimentación más visitadas en España. Métodos: se introdujeron consecutivamente los términos ‘obesidad’, ‘anorexia’ y ‘bulimia’ en el buscador Google®. La calidad general de las páginas web se analizó mediante dos test, la certificación internacional HonCode ® y el test de Bermúdez-Tamayo et al.; la calidad de la información se analizó específicamente con el test DISCERN. Resultados: no observamos diferencias significativas en la calidad general entre las diferentes patologías estudiadas (p = 0,197), aunque las páginas web sobre anorexia obtuvieron las menores puntuaciones. Además, todas las páginas web mostraron deficiencias significativas respecto a la calidad de la información (p = 0,032). No obstante, las páginas sobre obesidad mostraron mayor calidad que las de anorexia. Discusión: la calidad general de las páginas sobre trastornos nutricionales es moderada, pero la calidad de la información que contienen es bastante deficiente. Hay que destacar que las páginas web sobre anorexia mostraron tanto la peor calidad como la peor información.

    There are few Spanish language interactive, technology-driven health education programs. Objectives of this feasibility study were to: 1) learn more about computer and technology usage among Hispanic women living in a rural community; and 2) evaluate acceptability of the concept of using an embodied conversational agent (ECA) computer application among this population. A survey about computer usage history and interest in computers was administered to a convenience sample of 26 women. A sample video prototype of a hospital discharge ECA was administered followed by questions to gauge opinion about the ECA. Data indicate women exhibited both a high level of computer experience and enthusiasm for the ECA. Feedback from community is essential to ensure equity in state of the art dissemination of health information. Hay algunos programas interactivos en español que usan la tecnología para educar sobre la salud. Los objetivos de este estudio fueron: 1) aprender más sobre el uso de computadoras y tecnología entre mujeres Hispanas que viven en comunidades rurales y 2) evaluar la aceptabilidad del concepto de usar un programa de computadora utilizando un agente de conversación encarnado (ECA) en esta población. Se administro una encuesta sobre el historial de uso y del interés de aprender sobre computadoras fue a 26 mujeres por muestreo de conveniencia. Un ejemplo del prototipo ECA en forma de video de un alta hospitalaria fue administrado y fue seguido por preguntas sobre la opinión que tenían del ECA. Los datos indican que las mujeres mostraron un alto nivel de experiencia con las computadoras y un alto nivel de entusiasmo sobre el ECA. La retroalimentación de la comunidad es esencial para asegurar equidad en la diseminación de información sobre la salud con tecnología de punta. PMID:26671558

    Plasma soluble leptin receptor (sOB-R) levels were inversely associated with diabetes risk factors, including adiposity and insulin resistance, and highly correlated with the expression levels of leptin receptor, which is ubiquitously expressed in most tissues. We conducted a genome-wide association study of sOB-R in 1504 women of European ancestry from the Nurses' Health Study. The initial scan yielded 26 single nucleotide polymorphisms (SNPs) significantly associated with sOB-R levels (P < 5 × 10−8); all mapping to the leptin receptor gene (LEPR). Analysis of imputed genotypes on autosomal chromosomes revealed an additional 106 SNPs in and adjacent to this gene that reached genome-wide significance level. Of these 132 SNPs (including two non-synonymous SNPs, rs1137100 and rs1137101), rs2767485, rs1751492 and rs4655555 remained associated with sOB-R levels at the 0.05 level (P = 9.1 × 10−9, 0.0105 and 0.0267, respectively) after adjustment for other univariately associated SNPs in a forward selection procedure. Significant associations with these SNPs were replicated in an independent sample of young males (n = 875) residing in Cyprus (P < 1 × 10−4). These data provide novel evidence revealing the role of polymorphisms in LEPR in modulating plasma levels of sOB-R and may further our understanding of the complex relationships among leptin, leptin receptor and diabetes-related traits.

    Objetivo: Comparar la eficacia relativa de infliximab, adalimumab y golimumab mediante comparaciones indirectas (CI) ajustadas. Métodos: Se realizó una búsqueda bibliográfica que abarcó hasta Octubre 2013. Las bases de datos consultadas fueron: MEDLINE, EMBASE, the Cochrane Library, the Centre for Reviews and Dissemination y the Web of Science. Se incluyeron ensayos clínicos aleatorizados (ECA) que compararan la eficacia de infliximab, adalimumab o golimumab frente a placebo en términos de remisión clínica, respuesta clínica y curación de la mucosa. En el caso de que se incluyera más de un ECA para un mismo fármaco se llevó a cabo un metanálisis utilizado el modelo de efectos fijos. Las CI se realizaron utilizando el método de Butcher et al. Resultados: Se incluyeron 6 ECA publicados en 5 artículos: 2 para infliximab (ACT 1 y ACT 2), 2 para adalimumab (ULTRA 1 y ULTRA 2) y 2 para golimumab (PURSUIT-SC y PURSUIT-M). Los tres agentes biológicos presentaron mayor eficacia que placebo. Los resultados de las CI fueron los siguientes: en relación a la remisión clínica, en el período de inducción y en el período de mantenimiento, no hubo diferencias estadísticamente significativas entre los tres fármacos anti-TNF. En relación a la respuesta clínica y a la curación de la mucosa, en el período de inducción hay diferencias estadísticamente significativas entre infliximab y adalimumab. Conclusiones: En base a los resultados obtenidos (eficacia similar), infliximab, adalimumab y golimumab parecen ser alternativas terapéuticas. Así, otras consideraciones como la seguridad, la tolerancia y el coste-efectividad deben considerarse a la hora de seleccionar el tratamiento más adecuado.

    Serotonin (5-HT) and the hormone leptin have been linked to the underlying neurobiology of appetite regulation with evidence coming from animal and cellular research, but direct evidence linking these two pathways in humans is lacking. We examined the effects of reduced brain 5-HT synthesis due to acute tryptophan depletion (ATD) on levels of soluble leptin receptor (sOb-R), the main high-affinity leptin binding protein, in healthy adults using an exploratory approach. Women, but not men, showed reduced sOb-R concentrations after ATD administration. With females showing reduced baseline levels of central 5-HT synthesis compared to males diminished brain 5-HT synthesis affected the leptin axis through the sOb-R in females, thereby potentially influencing their vulnerability to dysfunctional appetite regulation and co-morbid mood symptoms.

    The presence of leptin (OB) and soluble OB receptor (s-OB-R) in gingival tissue extract and gingival crevicular fluid has led the studies investigating the relationship between OB and periodontal diseases. This study aims to investigate the levels of OB and s-OB-R in serum and their presence in gingiva of healthy controls (HC), gingivitis (G), aggressive periodontitis (AP), and chronic periodontitis (CP) patients; and whether correlations exist between clinical and serum parameters, OB and s-OB-R. Seventy-seven subjects [HC (n = 20), G (n = 20), CP (n = 21), and AP (n = 16)] were included in this study. After the clinical periodontal parameter recordings and venous blood sampling, gingival tissues obtained. Serum parameters' levels determined with enzyme linked immune sorbent assay; and OB and OB-R in gingiva immunohistochemically. No significant differences were observed regarding the serum parameters [high sensitivity C-reactive protein (hs-CRP), lipids, OB, and s-OB-R] when the groups were compared (P > 0.0125). The serum OB has positive correlations with hs-CRP in the G group (P < 0.05), and s-OB-R has presented significant negative correlations with BOP in HC group (P < 0.05), with hs-CRP in G (P < 0.05) and AP groups (P < 0.05). The positive correlations were observed between the serum OB and HDL and body mass index in the CP group (P < 0.05). In all of the tissue samples of all groups, there was positive OB and OB-R immunoreactivity in the gingival epithelium. The gingival tissues contain both OB and OB-R. The serum levels of OB and s-OB-R do not vary between patients and with different periodontal conditions.

    Leptin (LEP) is associated with appetite regulation and metabolism. Concentration is linear with adiposity, suggesting LEP resistance. LEP circulates freely and bound with its soluble receptor (sOB-r); the ratio is the free leptin index (FLI), an index of leptin resistance; lower FLI suggests reduced biological action. Purpose. The aim was to determine the effect of changes in adipose tissue distribution on LEP, sOB-r, and FLI following 6 months (6 M) of a diet/exercise weight loss program (WLP). In addition, we aim to identify predictors of the FLI. Methods. 6 M WLP consisted of diet/lifestyle interventions following ADA guidelines. Body composition was assessed by DXA. LEP and sOB-r analysis were done via ELISA. Results. 10 adults completed the WLP. Significant reductions were seen in total fat percentage (% fat), nontrunk fat, (NTF), and trunk fat (TF) from base to 3 m and 6 M (p ≤ 0.05). The FLI were reduced at 3 M and 6 M for males and 6 M for females. Total body fat and body weight predicted the FLI in both sexes. Conclusions. LEP and FLI reductions following 6 M of WLP were achieved independent of sOB-r changes. We also demonstrate that the FLI can be predicted noninvasively through total fat mass and body weight in kilograms. PMID:28050279

    2016-01-01

    Objective The aim was to study the role of leptin in the development of dementia. Methods Follow-up of the ALEXANDROS cohorts, with baseline measurements in 2000. From 1,136 available subjects free of dementia at baseline, 667 subjects had frozen baseline blood samples for measuring leptin and soluble leptin receptor (sOB-R). The free leptin index (FLI) was calculated as the ratio of leptin to sOB-R. Dementia was defined as an MMSE score <22 and a score >5 in the Pfeffer Activities Questionnaire. Results After 15 years of follow-up, 42 incident cases of dementia were identified. No difference in serum leptin was observed between people with and without dementia, but sOB-R was higher in demented than in nondemented subjects (sOB-R: 44.94 ± 23.97 vs. 33.73 ± 21.13 ng/ml). The adjusted risk for dementia increased, the higher the log sOB (hazard ratio = 3.58; 95% CI 1.72-7.45, p = 0.001). Conclusion Lower availability of free leptin was found in demented than in nondemented people, suggesting a role of leptin in cognition. PMID:27504118

    2013-01-01

    Objetivo: Comprobar si un programa de entrenamiento vibratorio de corta duración tiene algún efecto sobre la masa magra (MM) en personas mayores. Método: 49 personas mayores no institucionalizadas (20 hombres) participaron en el estudio. Los participantes que reunieron los criterios de inclusión fueron distribuidos al azar en el grupo de entrenamiento o el grupo control. Un total de 24 personas entrenaron sobre una plataforma vibratoria 3 veces por semana durante 11 semanas. Mediante absorciometría fotónica dual de rayos X se evaluó la MM del cuerpo completo, brazos y piernas. Se utilizó ANOVA de medidas repetidas para determinar los efectos de la intervención sobre las variables estudiadas y también para determinar los cambios intra-grupo a lo largo del periodo de intervención, incluyendo la edad y altura como variables de confusión. Resultados: 11 semanas de entrenamiento vibratorio no produjeron ningún cambio sobre la MM en ninguna de las regiones. Conclusión: Un programa de entrenamiento vibratorio de corta duración no es suficiente para producir cambios significativos en la masa magra en personas mayores no institucionalizadas.

    2015-04-01

    Introduccion. La expresion facial de las emociones tiene una funcion social importante que facilita la interaccion entre las personas. Este proceso tiene una base neurologica, que no se aisla del contexto ni de la experiencia acumulada por la interaccion entre las personas en dicho contexto. Sin embargo, hasta la fecha, no se conocen con claridad los efectos de la experiencia sobre la percepcion de las emociones. Objetivos. Discutir que funcion desempeña la experiencia en el reconocimiento de la expresion facial de las emociones y analizar los sesgos que las experiencias negativas y positivas podrian tener sobre la percepcion emocional. Desarrollo. La maduracion de las estructuras que soportan la capacidad para reconocer la emocion pasa por un periodo sensible durante la adolescencia, donde la experiencia adquirida puede tener mayor impacto sobre el reconocimiento emocional. Experiencias de abuso, maltrato, abandono, guerras o estres generan un sesgo hacia las expresiones de ira y tristeza. De igual manera, las experiencias positivas dan lugar a un sesgo hacia la expresion de alegria. Conclusiones. Solo cuando las personas son capaces de utilizar la expresion facial de las emociones como un canal de comprension y expresion interaccionaran de manera adecuada con su entorno. Este entorno, a su vez, dara lugar a experiencias que modulan dicha capacidad. Por lo tanto, es un proceso autorregulatorio que puede ser dirigido a traves de la implementacion de programas de intervencion sobre los aspectos emocionales.

    Introducción: El objetivo fue evaluar los efectos de la administración de glutamina sobre la regresión tumoral y sobre el tejido sano en pacientes con cáncer rectal que recibieron quimiorradioterapia. Material y métodos: Se incluyó 10 pacientes con cáncer rectal operado después de quimiorradioterapia, un subgrupo de un ensayo clínico que comparó glutamina con placebo en la prevención de enteritis aguda. Un patólogo experto analizó las muestras de tumor y tejido sano, buscando datos de regresión tumoral, mucífagos y daño por radiación. Resultados: No hubo diferencias entre placebo y glutamina en el grado de regresión tumoral. Todos los pacientes con glutamina presentaron mucífagos, frente al 28,6% con placebo (p = 0,038). El daño sobre tejido sano fue similar en los pacientes con glutamina y placebo, y entre aquellos con y sin enteritis. Conclusión: La glutamina no ejerce un efecto protector frente a la quimiorradioterapia sobre el tumor o el tejido rectal sano.

    Se han detectado en el espacio distintos compuestos binarios policarbonados (que se pueden formular como CnX), algunos de ellos con elementos de la primera fila del sistema periódico, pero también existen otros que contienen elementos de la segunda fila, como azufre o silicio. La información experimental sobre estos últimos compuestos es escasa, por lo que los estudios teóricos son especialmente valiosos en este campo. En esta comunicación presentaremos los avances mas recientes que sobre el tema ha realizado nuestro grupo. Incidiremos particularmente en dos aspectos. En primer lugar resumiremos los estudios en los que hemos intentado proporcionar información estructural sobre carburos metálicos formados por sodio, magnesio, aluminio o calcio, que pueda ser de ayuda a la hora de caracterizar estas moléculas en laboratorio como paso previo a su eventual detección en el espacio. Un aspecto importante dentro de este primer apartado es el análisis de las propiedades moleculares en función del tamaño del sistema (cuantificado en el numero de átomos de carbono) con el objeto de intentar sistematizar su estudio. En segundo lugar comentaremos brevemente algunos de los estudios realizados sobre posibles reacciones que pueden ser vías de síntesis de este tipo de compuestos en el medio interestelar.

    Introduccion. Los trastornos del espectro autista (TEA) son condiciones neuropsiquiatricas comunes y complejas en las que estan involucrados diversos factores. Objetivo. Revisar el conocimiento actual sobre los posibles factores de riesgo para los TEA. Desarrollo. Se investigo sobre factores potenciales de riesgo para los TEA, y se recabo informacion sobre trastornos y genes en las bases de datos de Medline, OMIM y Ensembl. Conclusiones. En los TEA se presenta una notoria heterogeneidad genetica y probablemente distintos modos de transmision. Ademas, muchos casos se asocian con mutaciones de novo o con alelos raros con un efecto probablemente importante. La heredabilidad en estos trastornos puede ser menor a la estimada anteriormente. Una fraccion de esta puede ser explicada por alelos relativamente comunes con un efecto debil. El ambiente perinatal y posnatal, la epigenetica, la edad del padre y, posiblemente, la de los abuelos varones cuando nacieron sus respectivos hijos son relevantes en los TEA. Estos ultimos podrian relacionarse con el desarrollo y la conectividad de las sinapsis, la neurotransmision, la señalizacion, la neuroplasticidad y la expresion genetica. Diversos tipos de estudios han contribuido a entender la etiologia de los TEA. Los estudios de enlace genetico y asociacion no son apropiados cuando hay mutaciones nuevas con efecto importante. Finalmente, el incremento en la prevalencia de los TEA podria deberse a una mayor conciencia sobre los trastornos, a cambios en los criterios diagnosticos y exposiciones ambientales, a modificaciones epigeneticas y a un numero creciente de mutaciones de novo que incrementan el riesgo a los trastornos.

    Introduccion. En el tratamiento logopedico de las dificultades de habla se practican dos enfoques metodologicos antagonicos: los no verbales, basados en ejercicios de motricidad oral (EMO), y los verbales, que se basan en tareas de procesamiento de habla con silabas, fonemas y palabras. En España, los programas de EMO se llaman 'programas de praxias', estan muy difundidos y son apreciados por los logopedas. Objetivo. Revisar los estudios sobre la eficacia de los tratamientos basados en EMO aplicados a niños con trastornos de habla y los argumentos teoricos que podrian justificar o no su utilidad. Desarrollo. Durante las ultimas decadas se han acumulado pruebas sobre la falta de eficacia de este enfoque en el tratamiento de los trastornos evolutivos del habla y en las dificultades de pronunciacion de poblaciones sin alteracion neurologica de la funcion motriz. La American Speech-Language-Hearing Association ha desaconsejado su uso atendiendo a los principios de practica basada en la evidencia. Los conocimientos acumulados sobre el control motor demuestran que el patron de movilidad y su correspondiente organizacion cerebral son diferentes en el habla y en otras funciones no verbales ligadas a la alimentacion y la respiracion. Conclusiones. Ni los estudios sobre su eficacia ni los argumentos a partir de estudios del control motor aconsejan el uso de los programas basados en EMO para el tratamiento de las dificultades de pronunciacion en niños con trastornos evolutivos del lenguaje.

    Adipokines are biologically active, low-molecular weight peptides, which play a major role in metabolic homeostasis in humans. Leptin has gained increasing attention in pediatrics as a biomarker for various metabolic pathologies. Yet, its usefulness is hampered by the relative lack of reference values from pediatric settings. Accordingly, this study aims to evaluate serum concentrations of leptin, soluble leptin receptor (sOB-R), and free leptin index (FLI) in healthy Danish schoolchildren aged 6-18 years and subsequently to establish reference intervals across sex and age groups. A total of 1193 healthy, non-obese Danish schoolchildren (730 girls, 463 boys) aged 6-18 years (median 11.9) were examined by trained medical staff. Serum leptin and sOB-R concentrations in venous fasting blood samples were quantitated by immunoassay. Percentile curves of leptin, sOB-R, and free leptin index were calculated using the General Additive Model for Location Scale and Shape (GAMLSS). Significant age and sex-dependent differences in circulating leptin levels were found. In boys, the median leptin concentration for all ages combined was 3.35 μg/L (95%-interval: 0.71-22.47) and in girls, it was 9.89 ng/L (95%-interval: 2.06-41.49). For SOB-R, no sex-specific difference was found, and the median sOB-R concentration was 8.24 μg/L (IQR: 3.58-23.74; range: < 1.56-744.15). We demonstrated an age-dependent correlation with both serum leptin concentration and free leptin index with a gradual and significant increase in girls throughout childhood and adolescence and a significantly higher leptin concentration and free leptin index bell-shaped peak in early adolescence in boys.

Conocer cuales son las fuentes de informacion, los temas sobre salud mas consultados y la confianza en el material obtenido de la red por un grupo de lesionados medulares espanoles usuarios de Internet. Pacientes y metodos. Realizamos una encuesta a lesionados medulares espanoles mediante un cuestionario en Google Drive. Se accedia a el mediante un enlace en la pagina de ASPAYM-Asturias. El cuestionario incluia datos epidemiologicos y cuestiones sobre Internet, fuentes de informacion y confianza en ellas. Resultados. Contestaron 121 lesionados medulares (el 64%, hombres), con una edad media de 45 anos. La etiologia predominante era la traumatica (70%), y en el 72%, las lesiones eran paraplejias. El 83% prefiere consultar al personal sanitario. Busca en Internet mas del 70% de la muestra, y lo hace en paginas web en espanol. El tema de mayor interes es el material ortopedico. El 27% confia mucho o bastante en la informacion de la red, mientras que el 32% lo hace poco o nada. Conclusiones. Los resultados nos aproximan al uso de Internet que hacen los lesionados medulares espanoles. Asumiendo el sesgo inherente en un estudio de este tipo, mas del 70% de la muestra consulta sobre su salud en la red, sobre todo en paginas web espanolas. El tema mas buscado es 'material ortopedico y sillas de ruedas'. Solo uno de cada cuatro confia en los contenidos de la red, y la mayoria prefiere consultar sus problemas de salud directamente con los profesionales sanitarios.

    Introducción: Es importante evaluar el papel de los alimentos tipo «snacks» sobre el apetito. El objetivo de este trabajo fue evaluar la respuesta en términos de saciedad y el efecto sobre factores de riesgo cardiovascular de dos galletas diferentes. Material y Métodos: Se randomizaron 38 pacientes: grupo I (galleta enriquecida en FOS, n=19) y grupo II (galleta control, n=19). Antes de la intervención nutricional y tras un mes, a los pacientes se les valoró la saciedad con un test de prueba con 5 galletas. Resultados: Tras el test de prueba, el area bajo la curva del test de saciedad fue mayor con la galleta saciante que con la galleta control, detectándose el mismo resultado con el test trás 1 mes de ingerir las galletas. Analizando los diferentes tiempos, el score de saciedad mostró una puntuación superior en los tiempos 20 y 40 minutos frente al valor basal (tiempo 0) tras la ingesta de la galleta saciante, comparado con la galleta control. Los valores de saciedad en los tiempos (20 minutos y 40 minutos) fueron superiores que los que presentó la galleta control. Este resultado fue similar, al realizar el test tras 1 mes tomando la galleta saciante. Los resultados fueron similares al utilizar una escala visual de saciedad de 100 mm con 5 cuestiones. No se detectaron efectos sobre los factores de riesgo cardiovascular tras la intervención nutricional, ni sobre la ingesta dietética global. Conclusion: La galleta enriquecida en FOS produce mayores niveles de saciedad que la galleta control. Sin embargo no existieron efectos sobre los factores de riesgo cardiovascular ni la ingesta dietética global.

    Introduccion. La adhesion al tratamiento es un factor que esta repercutiendo en la eficacia de los farmacos antiepilepticos. El levetiracetam es un principio activo cuya eficacia y seguridad estan ampliamente demostradas y que esta disponible en diferentes formulaciones orales (sobres, comprimidos y solucion oral), pero la informacion sobre la adhesion/cumplimiento del tratamiento con estas formulaciones orales es escasa. Objetivo. Conocer la adhesion al tratamiento con formulaciones de levetiracetam (granulado en sobre y comprimidos) en adultos y ancianos. Pacientes y metodos. Estudio observacional retrospectivo no intervencionista. Durante los tres meses previos al estudio debia estar en tratamiento con levetiracetam (granulado en sobre o comprimidos), bien en monoterapia o en combinacion. Se valoraron los tests de cumplimiento (cuestionario de Morisky-Green modificado), asi como un cuestionario de satisfaccion del investigador y del paciente/cuidador. Los datos se analizaron con el programa SPSS v. 21.0. Resultados. Un total de 466 pacientes completaron el estudio. La edad media fue de 52,75 ± 19,17 años, y la media en los mayores de 65 años fue de 72,79 ± 6,15 años. Un 55,4% eran hombres. El cumplimiento se relaciona con la variable 'formulacion galenica' y con la edad (p = 0,031). El riesgo de incumplimiento es un 86,4% mayor entre los que toman comprimidos frente a granulado de levetiracetam (odds ratio: 1,864). Asimismo, el incumplimiento es mayor entre los pacientes mayores de 65 años. El incumplimiento se relaciona con la atribucion de fallos de memoria. Conclusiones. Los pacientes mas mayores presentan mas dificultades en el cumplimiento. El granulado de levetiracetam en sobres favorece el cumplimiento.

    Regulators of adipose tissue hormones remain incompletely understood, but may include sex hormones. As adipose tissue hormones have been shown to contribute to numerous metabolic and cardiovascular disorders, understanding their regulation in midlife women is of clinical importance. Therefore, we assessed the associations between testosterone (T) and sex hormone binding globulin (SHBG) with leptin, high molecular weight (HMW) adiponectin, and the soluble form of the leptin receptor (sOB-R) in healthy midlife women. Cross-sectional analyses were performed using data from 1,881 midlife women (average age 52.6 (±2.7) years) attending the sixth Annual follow-up visit of the multiethnic Study of Women's Health Across the Nation. T was weakly negatively associated with both HMW adiponectin and sOB-R (r = -0.12 and r = -0.10, respectively; P < 0.001 for both), and positively associated with leptin (r = 0.17; P < 0.001). SHBG was more strongly and positively associated with both HMW adiponectin and sOB-R (r = 0.29 and r = 0.24, respectively; P < 0.001 for both), and more strongly and negatively associated with leptin (r = -0.27; P < 0.001). Adjustment for fat mass, insulin resistance, or waist circumference only partially diminished associations with HMW adiponectin and sOB-R, but attenuated associations with leptin. In conclusion, in these midlife women, lower SHBG values, and to a lesser extent, higher T levels, were associated with lower, or less favorable, levels of adiponectin and sOB-R, independent of fat mass. These data suggest that variation in these adipose hormones resulting from lower SHBG levels, and possibly, though less likely, greater androgenicity, may contribute to susceptibility for metabolic and cardiovascular outcomes during midlife in women.

    Introducción: el estado nutricional previo de la embarazada, la adecuada ganancia de peso y la ingesta de ciertos nutrientes pueden tener una influencia importante tanto para la madre como para el recién nacido, a corto y largo plazo. Las recomendaciones de la Organización Mundial de la Salud son transmitidas durante el control del embarazo por la matrona.Objetivos: analizar los principales estudios sobre la percepción de las embarazadas acerca de los consejos nutricionales recibidos e identificar las estrategias utilizadas por las matronas para su implementación.Metodología: búsqueda bibliográfica sobre embarazadas de bajo riesgo controladas por matronas y que reciben consejos nutricionales realizada en WOS, CINHAL y PubMed. Se utilizaron los descriptores: pregnancy, pregnant, midwife, counselling, nutritiony sus diferentes combinaciones. Los criterios de inclusión fueron artículos originales y revisiones en inglés, español o portugués de los últimos diez años y disponibles en texto completo.Resultados: se encontraron 184 referencias. Solo 11 tratan el tema abordado. Existen múltiples artículos con consejos nutricionales en el embarazo, pero muy pocos que incluyan estrategias educativas implementadas por las matronas que aborden recomendaciones dietético-nutricionales y su utilidad.Conclusión: existen escasos estudios que investiguen los conocimientos que las matronas tienen sobre nutrición en el embarazo y los consejos que aportan sobre el tema. Igualmente sucede con los trabajos que estudian la percepción que tienen las gestantes sobre los consejos nutricionales recibidos.

  18. Tools for evaluating Lipolexis oregmae (Hymenoptera: Aphidiidae) in the field: Effects of host aphid and host plant on mummy location and color plus improved methods for obtaining adults

    Lipolexis oregmae Gahan was introduced into Florida in a classical biological control program directed against the brown citrus aphid, Toxoptera citricida (Kirkaldy), on citrus. Prior to evaluating distribution, host range, and potential nontarget effects of L. oregmae in Florida, we evaluated the role of other potential host aphids and host plants on mummy production and location. Under laboratory conditions, this parasitoid produced the most progeny on the target pest, the brown citrus aphid on citrus. This parasitoid, unlike the majority of aphidiids, did not produce mummies on any of the host plants tested when reared in black citrus aphid T. aurantii (Boyer de Fonscolombe) on grapefruit, spirea aphid Aphis spiraecola Patch on grapefruit and pittosporum, cowpea aphid A. craccivora Koch on grapefruit and cowpeas, or melon aphid A. gossypii Glover on grapefruit and cucumber. Thus, sampling for L. oregmae mummies of these host aphids and host plants must involve holding foliage in the laboratory until mummies are produced. This parasitoid requires high relative humidity to produce adults because no adults emerged when mummies were held in gelatin capsules, but high rates of emergence were observed when mummies were held on 1.5% agar plates. In addition, we compared the color of 6 aphid hosts and the color of mummies produced by L. oregmae when reared in them to determine if color of mummies could be used to identify L. oregmae . Mummy color varied between aphid hosts and tested host plants, and is not a useful tool for identifying L. oregmae for nontarget effects.

    Fundamento. Existen pocos estudios sobre las actitudes de los médicos de los servicios de urgencias respecto a sus organizaciones. La actitud de los trabajadores "compromiso con la organización" ha mostrado ser relevante para el rendimiento en el puesto de trabajo y el global de las organizaciones. El objetivo de este trabajo es analizar el grado de compromiso de los médicos de urgencias de los servicios públicos españoles y los posibles determinantes del mismo.Método. Encuesta en línea a médicos de servicios de urgencias de hospitales públicos españoles mediante la aplicación informática SurveyMonkey.Resultados. Se obtuvieron 205 respuestas, de las que 162 correspondían a médicos de urgencias y 43 a jefes de servicio. Los resultados reflejan un nivel medio de compromiso, siendo la modalidad de compromiso afectivo la que presenta un nivel más bajo y la de compromiso de continuidad el nivel más alto. Las capacidades del médico y la opinión que los mismos tienen sobre lo bien que está organizado su servicio influyen sobre el grado de compromiso afectivo, mientras que la formación específica en urgencias y la antigüedad lo hacen sobre el compromiso de continuidad.Conclusiones. Los médicos de urgencias manifiestan un sentido de obligación con el servicio del hospital en el que trabajan de nivel medio (3,8 en una escala de 1 a 5), sienten un afecto medio por el mismo (3,4), y tienen una elevada intención de continuar en su hospital (4,0). Los medios de los que dispone el hospital en función de su nivel no influyen sobre este nivel de compromiso, mientras que la formación y percepción del médico sobre su servicio sí que la tienen.

    Kim, Youn Jong; Hamm, Se-Yeong

    /EGIS peut servir d'outil d'évaluation du potentiel de pollution et ainsi faciliter des plans de protection des ressources en eau souterraines. Resumen La contaminación de aguas subterráneas, debida a la expansión industrial y al fuerte crecimiento demográfico, supone un gran problema medioambiental en Corea del Sur. También en áreas rurales, el incremento en el uso de fertilizantes y pesticidas, el drenaje de minas y el aumento de los caudales de aguas residuales provocan un aumento de la contaminación. Para evaluar el riesgo de contaminación de las aguas subterráneas en el área de la ciudad de Cheongju, el primero de una serie de estudios piloto, se utilizó el modelo DRASTIC/EGIS. Este modelo permite la zonificación del área de estudio, basada en consideraciones geológicas e hidrogeológicas. En cada una de las zonas se aplica un esquema de clasificación que evalúa su vulnerabilidad relativa. El modelo DRASTIC/EGIS puede servir como una herramienta para evaluar el riesgo potencial de contaminación que facilite la creación de programas de protección de los recursos subterráneos.

    Bersten, M.; Landau, S.; Vucetich, H.

    Las diferentes teorías que unifican las cuatro interacciones fundamentales coinciden en predecir variaciones temporales y espaciales de las constantes fundamentales pero difieren en la forma de esta variación. Las observaciones astronómicas y geofísicas permiten establecer cotas sobre la variación de dichas constantes. ésto nos proporciona una herramienta importante para testear las diferentes teorías. En particular, se utilizó el modelo de supercuerdas propuesto por Damour y Polyakov. Se obtuvieron límites sobre los parámetros libres de dicho modelo consistentes con un conjunto de datos astronómicos y geofísicos.

    The introduction of inhaled anesthetics to Spain in 1847 brought appearances by enthusiastic promotors, prudent and reserved admirers and stubborn adversaries - sparking controversy over the use of the new gases. In some cases debate involved the discussion of various concepts of pain, as is shown by heated exchanges among Eusebio Castelo Serra, Manuel Santos Guerra and Zacarías Benito González in the pages of the journal Boletín de Medicina, Cirugía y Farmacia, in three articles appearing between 1850 and 1851 on the concept of pain: Sobre el dolor de las enfermedades y principalmente en las operaciones quirúrgicas, Modificación de dos instrumentos and Estudios sobre el dolor. Investigation into the authors' biographies and an analysis of the content of the articles has permitted us to reconstruct some aspects of the concept of pain in Spain in the middle of the nineteenth century.

  9. Estabilidad de los modelos de Heggie y Ramamani

    Los modelos de Heggie y Ramamani de satélites galácticos en órbitas circulares se basan en una teoría aproximada, por lo que es importante verificar su estabilidad mediante simulaciones numéricas. En esta forma, hemos logrado mostrar que son estables sobre intervalos de tiempo mucho mayores que los que lograron los propios autores de los modelos. Por otra parte, dado que hemos mostrado que el caos es significativo en estos modelos, son un sistema ideal para investigar si, pese a ello, se mantienen estacionarios. Nuestras simulaciones numéricas muestran que, pese al caos, la estacionariedad se mantiene sobre intervalos de centenares de tiempos de cruce del sistema, mucho mayores que los tiempos de Liapunov característicos de sus movimientos caóticos.

    In obese individuals, weight loss might be affected by variants of the adipokine-encoding genes. We verified whether selected functional single nucleotide polymorphisms in LEP, LEPR and ADIPOQ are associated with changes in serum levels of the respective adipokines and weight loss in 100 prepubertal obese (SDS-BMI > 2) Caucasian children undergoing lifestyle intervention. Frequencies of the -2548G > A LEP, Q223R LEPR, K656N LEPR, -11377C > G and -11426A > G ADIPOQ polymorphisms were analyzed by restriction fragment length polymorphism. Serum adipokine and soluble leptin receptor (sOB-R) concentrations were measured using the ELISA method. Among the analyzed polymorphisms, only LEPR polymorphisms were associated with changes of SDS-BMI or sOB-R concentrations in children after therapy. Carriers of the wild-type K665N and at least one minor Q223R allele had the greatest likelihood of losing weight (OR = 5.09, p = 0.006), an increase in sOB-R (ptrend = 0.022) and decrease in SDS-BMI correlated with the decrease of fat mass (p < 0.001). In contrast, carrying of the wild-type Q223R and at least one minor K665N allele were associated with a decrease in sOB-R concentrations and a decrease in SDS-BMI correlated with a decrease in fat-free mass (p = 0.002). We suggest that the combination of different LEPR variants, not a single variant, might determine predisposition to weight loss in the prepubertal period. PMID:27240401

    Introducción: Las múltiples ventajas que aporta a la salud la práctica de una actividad física de forma continuada son conocidas. Aunque es importante en todas las etapas de la vida, cuando llega la gestación aparecen algunas dudas sobre la conveniencia de realizar ejercicio físico, así como del tipo de actividad, de su frecuencia, intensidad y duración. Objetivo: Analizar los principales estudios sobre la influencia de la actividad física sobre los parámetros materno- fetales. Método: Revisión sistemática de programas de actividad física destinados a las mujeres embarazadas y sus resultados durante el embarazo, el parto y el postparto. Se identificaron 45 artículos a través de la búsqueda automatizada en las bases de datos PUBMED, Scopus y Google Scholar; se llevó a cabo entre los meses de octubre de 2013 y marzo de 2014. Para seleccionar los artículos fue preciso considerar la utilidad y la relevancia del tema estudiado y la credibilidad o experiencia de los autores en la temática. Se tuvo en cuenta la validez interna y externa de cada uno de los artículos revisados. Conclusiones: Los resultados de la revisión ponen de manifiesto la importancia de la actividad física durante el periodo gestacional y se constata que la información disponible en la actualidad puede servir de referente inicial para continuar profundizando en los resultados que sobre la salud materno fetal tiene la práctica de actividad física en el medio acuático.

    Antecedentes: En la mayoría de los países latinoamericanos existe una deficiencia de micronutrientes, retraso en el crecimiento, y altas tasas de morbilidad y mortalidad infantil. En la actualidad se ha asociado la deficiencia de zinc con el retraso del crecimiento infantil. El propósito de esta revisión, fue analizar artículos sobre estudios aleatorizados que evaluaron el efecto de la suplementación con zinc y el crecimiento infantil. Metodología: Se realizó una búsqueda electrónica de la literatura en la base de datos de PubMed con las palabras claves “Micronutrient supplementation and growth”, publicados de enero de 2005 a abril de 2013. Se identificaron 34 estudios aleatorizados controlados (EAC) realizados en Latinoamérica, de los cuales cinco reunieron los criterios de inclusión. Se añadió un estudio referido por otros autores. Resultados: Los estudios se realizaron en Brasil, Cuba, Perú, Ecuador, y Guatemala. En ningún estudio se observó el efecto positivo del zinc sobre el crecimiento lineal. Conclusión: La revisión realizada sugiere que la suplementación con zinc no tiene un efecto significativo sobre el crecimiento lineal; sin embargo, podría tener beneficios sobre el crecimiento en niños con deficiencia de zinc si se añaden otros nutrientes en deficiencia.
