Abstract: Introducción: El polimorfismo de inserción/deleción del gen de la enzima convertidora de angiotensina es uno de los marcadores de predisposición a enfermedades más estudiados del eje renina-angiotensina. Los hallazgos contradictorios de estudios de su asociación con diversas afecciones hacen necesario tipificar previamente las poblaciones de interés. Objetivos: Caracterizar el comportamiento de este polimorfismo en los principales grupos raciales cubanos: caucasoide y negroide. Métodos: Mediante un método basado en la reacción en cadena de la polimerasa se genotipificaron 93 muestras de sangre periférica obtenidas de adultos aparentemente sanos (49 caucasoides y 44 negroides). Se calcularon las frecuencias alélicas y genotípicas grupales. Resultados: Los genotipos ID y DD predominaron en los grupos caucasoide y negroide, respectivamente. La comparación de las frecuencias genotípicas entre ambos grupos evidenció diferencias significativas para el genotipo ID. El alelo D resultó el más frecuente en las 2 subpoblaciones estudiadas. Ambas se encuentran en equilibrio de Hardy-Weinberg para este polimorfismo. Las comparaciones de las distribuciones alélicas y genotípicas entre los grupos y poblaciones foráneas similares, no arrojaron diferencias significativas. Conclusiones: Los resultados permiten considerar los valores de frecuencias genotípicas y alélicas obtenidos como referencia para posteriores estudios de asociación con enfermedades en la población cubana e indican la necesidad de tener en cuenta las características particulares de este polimorfismo en cada grupo racial.

Abstract: This paper reflects the current situation surrounding indigenous teacher education by means of the construction of a dialogue among three educators, two of them nonindigenous educators involved with indigenous school education and one indigenous educator committed to the education of his people. Teacher education, situated in a socio-cultural way, is the center of attention in this paper. “Listening” as a way of talking with the “other” is one of the theoretical focuses of this exercise between teacher educators and teachers, which uses dialogue as a means to increase awareness. In the dialogic process mentione, it was possible to realize how rich a dynamic between educators from different cultural contexts can be. The desire of the indigenous educator and his/her people to contribute their ideas to the construction of the indigenous school became evident. This shows the great challenge for non-indigenous educators seeking to contribute to the organization of the school education of distinct indigenous nations. Keywords: Intercultural Dialogue. Teacher Education. Indigenous School Education. Este trabalho reflete a situa o atual em torno da forma o de professores indígenas por meio da constru o de um diálogo entre três educadores, dois deles educadores n oindígenas envolvidos com a educa o escolar indígena e um educador indígena comprometido com a educa o do seu povo. A forma o de professores, de modo sócioculturalmente situado, está no centro das aten es do trabalho. A “escuta” como um meio de falar com o “outro” é um dos focos teóricos desse exercício entre formadores e professores, o qual tem o diálogo como um meio para tomada de consciência. No referido processo dialógico foi possível perceber qu o rica pode ser uma dinamica entre educadores de contextos culturais diferentes. Ficou evidente a vontade do educador/povo indígena colocar suas idéias na constru o da escola indígena. Isso mostra o grande desafio colocado ao educador n o-indígena quando visa contribuir para a organiza o da educa o escolar de distintas na es indígenas. Palavras-chave: Diálogo Intercultural. Forma o de Professores. Educa o Escolar Indígena.

Jornal Português de Gastrenterologia , 2011,
Abstract: introduction: cirrhotic patients admitted in intensive care units (icu) have a poor prognosis. the prognosis of these patients can be evaluated with general scores (sofa, apache, saps) or with specific scoring systems for liver disease (meld, child-pugh). aims: to evaluate the prognostic value of general scores (sofa, apache and saps) and of liver-specific scores (meld and child-pugh) in patients with liver cirrhosis admitted to general icus or to gastroenterology intensive care units (gicu). material and methods: the authors present a literature review on the assessment of the prognosis of cirrhotic patients admitted to icus and also report your experience on this issue in the context of a specialized gicu including the analysis of 124 admissions. results: in several studies on patients with liver cirrhosis admitted to general icus, both general and liver-specific scores showed good discrimination, with an area under receiver operating characteristic curve (>auc) > 0.7. considering the six most representative studies, the mean value of auc on sofa, apache ii, apache iii, meld and child-pugh scores was 0.86, 0.74, 0.81, 0.79 and 0.77, respectively. the study of 124 consecutive cirrhotic admissions to a gicu showed that patients who died belonged exclusively to the class c of child-pugh and had average values of sofa, apache ii, saps ii and meld scores significantly higher than those of the patients who survived (10.1, 22.0, 47.5 and 30.7 in those who died and 3.5, 13.6, 25.3 and 18.0 in those who survived, respectively; p < 0.05). conclusions: both general scores and liver-specific scores have prognostic value in the risk assessment of patients with liver cirrhosis admitted to general icus or to gicus. in the icus the general scores, and particularly the sofa score, have better prognostic ability than the liver-specific scores.
