ABSTRACT
Resumen: En la actualidad, el contar con una base de datos que represente fisiológicamente a una región o estado de la república conlleva un esfuerzo en conjunto entre diversas instituciones. Debido a su inexistencia, los investigadores recurren a bases de datos extranjeras organizadas para el desarrollo de estudios. Un ejemplo es el desarrollo de algoritmos matemáticos de detección de patologías en relación a individuos con una población y una forma de vida diferente a la nuestra. PhysioBC®, tiene como objetivo difundir libremente datos fisiológicos adquiridos en la población de Baja California, a fin de que se desarrollen modelos precisos de detección de patologías acorde a la genética y forma de vida de nuestra comunidad. En este trabajo presentamos los pasos de creación de su primera sección de datos electrocardiográficos, debido a que los datos reportados por el INEGI en 2012, de las 14,756 muertes, el 19% tenían origen cardiovascular. Actualmente se cuenta con 50 registros tomados en la industria maquiladora de Mexicali y 64 tomados en voluntarios. Estos se dividen en estándar de 12 derivaciones y de alta resolución de 3 derivaciones. Todos ellos se encuentran libres para su descarga en diversos formatos en la misma plataforma PhysioBC®.
Abstract: Currently, having a database that represents physiologically a region or state of the republic involves a joint effort among research and clinical institutions. Due to their non-existence, researchers normally use foreign international databases organized for research purposes. One example is the development of mathematical algorithms for detecting pathologies in individuals with a population who have a different way of living than ours. PhysioBC®, aims to freely disseminate physiological data acquired in the population of Baja California, in order to develop precise models of pathology detection according to the genetics and way of living of our community. Because the data reported by INEGI in 2012, out of the 14,756 deaths, 19% had cardiovascular origin problems, in this paper, we present the steps of creating PhysioBC® first section, called electrocardiographic data. Currently we have 50 records taken in the manufacturing industry of Mexicali and 64 taken in volunteers. The records are divided into standard 12-lead and high-resolution 3-lead. All of them are free for download in different formats at PhysioBC® website.
ABSTRACT
Se propuso identificar los estilos de vida en adolescentes de una comunidad semiurbana, buscando respuesta a la pregunta: ¿Cuáles son los factores que se identifican en el instrumento Fantastic, en los estudiantes de la comunidad de Ixtlahuaca? Se trabajó con la variable de estilos de vida, ocupando el instrumento FANTASTIC. La muestra la conforman 1088 estudiantes, 603 hombres y 485 mujeres. La religión de mayor prevalencia es la católica con 844. Del instrumento se obtuvo una fiabilidad de .79, con 6 factores identificados: sentimientos negativos y estrés, satisfacción y pensamiento positivo, alimentación dañina, relajación y sueño, alcohol y tabaco, cafeína. Se concluye que se requiere manejo de hábitos saludables, prevención de adicciones y alimentación.
The proposal was to identify lifestyles among adolescents in a semi-urban community, seeking answers to the question: What are the factors that are identified in the Fantastic instrument in students Ixtlahuaca community? We worked with the lifestyle variable, holding the instrument FANTASTIC. The sample is formed by 1088 students, 603 men and 485 women. The most prevalent religion is Catholic with 844. The instrument yielded a reliability of .79, with 6 factors identified: negative feelings and stress, satisfaction and positive thinking, harmful food, relaxation and sleep, alcohol and snuff, caffeine. It is concluded that it is required management of healthy habits, addictions and alimentation prevention.
ABSTRACT
The serious neuropsychological repercussions of hepatic encephalopathy have led to the creation of several experimental models in order to better understand the pathogenesis of the disease. In the present investigation, two possible causes of hepatic encephalopathy, cholestasis and portal hypertension, were chosen to study the behavioral impairments caused by the disease using an object recognition task. This working memory test is based on a paradigm of spontaneous delayed non-matching to sample and was performed 60 days after surgery. Male Wistar rats (225-250 g) were divided into three groups: two experimental groups, microsurgical cholestasis (N = 20) and extrahepatic portal hypertension (N = 20), and a control group (N = 20). A mild alteration of the recognition memory occurred in rats with cholestasis compared to control rats and portal hypertensive rats. The latter group showed the poorest performance on the basis of the behavioral indexes tested. In particular, only the control group spent significantly more time exploring novel objects compared to familiar ones (P < 0.001). In addition, the portal hypertension group spent the shortest time exploring both the novel and familiar objects (P < 0.001). These results suggest that the existence of portosystemic collateral circulation per se may be responsible for subclinical encephalopathy.
