Abstract: Background: The development of strategies to reduce the prevalence of high blood pressure is an important challenge for all countries, populations, and governments. For this reason, the search of method in the prediction of the high blood pressure is an appropriate way, and a very important objective to get. Objetive: This study expects to show that cardiovascular hyperreactivity determined by the sustained weight test is a predictor of the high blood pressure independently from other cardiovascular risk factors. Methods: A five year cohort study was carried out (from 1998 to 2003) in which two groups were created. The 1st one with CHR (n = 41) and the 2nd one with (n= 127) of cardiovascular normoreactivity (CNR). Variables such as cardiovascular hyperreactivity high blood pressure, obesity, family history of high blood pressure, body mass index rate, smoking habit, salt consumption and alcohol consumption. An evaluation of the HBP risk was performed in each group, and the values of incidence of high blood pressure in each of them were compared. The chi square test was used as a statistic method. The stratified analysis and the determination of relative risk with a confidence interval of the 95 percent. The statistical significance was 95%. Results: The incidence of hypertension in the cohort of HRC was of 34,15/100 people and in the CNR of 10,24/100 people chi square = 13,3 GL= 1 P= 0,007, on the other hand, when we made adjustments according to different cardiovascular risk markers to determine the relationship between hypertension and hyperreactivity, it was observed that the relationship exists in spite of the risk marks mentioned before. Conclusions: The individuals whit HRC determined by the SWT have a risk to develop higher significant sustained hypertension then the cardiovascular normorreactivos ones this is an evidence that this method is useful to predict HBP. Fundamento: El desarrollo de estrategias para reducir la prevalencia de hipertensión arterial, es un desafío importante para todos los países. De lo anterior se desprende que la búsqueda de métodos que permitan la predicción de esa entidad, es un camino correcto y un objetivo muy importante a conseguir. Objetivo: Este estudio pretende demostrar que la hiperreactividad cardiovascular, determinada mediante la Prueba del Peso Sostenido, es un predictor de la hipertensión arterial. Métodos: Se desarrolló un estudio de cohorte de 5 a os de evolución 1998-2003, en el cual se crearon dos grupos, el primero de hiperreactivos cardiovasculares (n= 41) y el segundo de normorreactivos cardiovascular

Abstract: Por experiencia se sabe que las revistas médicas cubanas presentan dificultades desde el punto de vista editorial y de contenido. Con este antecedente se evaluaron dichas publicaciones, y se tomaron como referencia sus homólogas del área hispanolatinoamericana incluidas en bases de datos internacionales. A tal efecto se consultaron la base de datos MEDLINE y el fichero hemerográfico de la Biblioteca Médica Nacional; se revisaron físicamente todos los títulos de revistas médicas cubanas y se entrevistaron a sus respectivos editores, así como a los médicos asesores del Centro Nacional de Información de Ciencias Médicas. Se comprobó que las revistas hispanolatinoamericanas cumplen requisitos de calidad, que les permiten mantenerse incluidas en bases de datos de carácter selectivo, mientras que las cubanas se encuentran en estado de crisis, dada la baja calidad de su contenido y las marcadas deficiencias en su procesamiento editorial. Se somete a la consideración de los directivos de la Editorial Ciencias Médicas un proyecto de metodología, que puede constituir una guía de análisis de todos los factores que limitan o impiden el reconocimiento por parte de la comunidad científica de las revistas objeto de estudio, a la vez que servir de pauta para establecer estrategias que ayuden a paliar esta situación. It is know from experience that the Cuban medical journals have publishing and content difficulties. Taking this antecedent into consideration, these publications were evaluated using as a reference similar publications fron Spain and Latin America that are included in international databases. To this end, the MEDLINE database and the periodicals file of the National Medical Library were consulted. All the titles of the Cuban medical journals were physically reviewed and the publishers as well as the medical advisors of the National Center of Information on Medical Sciences were interviewed. It was proved that the journals from Spain and Latin America meet the quality requirements that alow them to be included in selective databases, whereas the Cuban journals are in a state of crisis due to the poor quality of their content and to the marked deficiencies found in their publishing processing. A methodology project that may be used as a guide to analyze all those factors limiting or impeding the acknowledgment of these journals on the part of the scientific community is put into the consideration of the board of directors of the Medical Sciences Publishing House. This project may also act as a model for establishing strategies that help to alleviate this sit

Abstract: Oxidative stress, a state of imbalance in the production of reactive oxygen species and nitrogen, is induced by a wide variety of factors. This biochemical state is associated with systemic diseases, and diseases affecting the central nervous system. Epilepsy is a chronic neurological disorder with refractoriness to drug therapy at about 30%. Currently, experimental evidence supports the involvement of oxidative stress in seizures, in the process of their generation, and in the mechanisms associated with refractoriness to drug therapy. Hence, the aim of this review is to present information in order to facilitate the handling of this evidence and determine the therapeutic impact of the biochemical status for this pathology.
