ABSTRACT
Despite the improvements in medical treatment over recent decades, hemophilia patients experience deterioration in their quality of life. This study provides a demographic and clinical characterization of hemophilia patients and how this affects their quality of life. This is based on a descriptive cross-sectional study on quality of life of 20patients with hemophilia from the Province of Curicó, Maule Region. The following antecedents were obtained from each patient: age, weight, height, severity of hemophilia, presence of hepatitis B virus, hepatitis C virus, human immunodeficiency virus and Chagas disease. To measure the quality of life the Short Form-36 survey was applied to each one of the patients. The average age was 35+/-16 years old and body mass index was 25+/-4 kg/m2. Regarding the severity level of the disease, in 55 percent of the patient it was found mild. More over, 25 percent of patients had hepatitis C. The most co-morbidity was for articular lesions. Quality of life is affected mainly by lack of sport and also due to the severity level of disease. The current challenge is to provide comprehensive care, both for patients and their families, where the main goal aims at restoring the sense of wellbeing, their right to be perceived as a person with capacity to develop.

The endothelium helps to maintain the normal structure and homeostasis of the vasculature. However, chronic exposure to cardiovascular (CV) risk factors causes endothelial dysfunction, a phenomenon that is characterized by inflammation, reduced bioavailability of nitric oxide (NO) and a prothrombotic state. Epidemiological studies have shown that regular consumption of fruits and vegetables reduces CV risk, which has caused interest in knowing the bioactive compounds and the mechanisms involved. Among the components that protect the endothelium are antioxidants (vitamin C, vitamin E and poly phenols) and polyunsaturated fatty acids. Vitamin C and E promote vasodilatation protecting NO by blocking the reactive oxygen species (ROS). Poly phenols improve endothelial function primarily by increasing levels of NO, and inhibition of angiogenesis and platelet activation. Diets rich in poly-unsaturated fatty acids have shown beneficial effects by reducing the gene expression of cyclooxygenase-2 and the expression of cell adhesion molecules. This review mainly highlights the current understanding of endothelial dysfunction and the protective effect of endothelial cells by bioactive components of fruits and vegetables.
El endotelio normal ayuda a mantener la estructura y la hemostasia vascular. Sin embargo, la exposición crónica a factores de riesgo cardiovascular (CV) produce disfunción endotelial, fenómeno que se caracteriza por inflamación, disminución en la biodisponibilidad de óxido nítrico (NO) y un estado protrombótico. Estudios epidemiológicos han demostrado que el consumo regular de frutas y hortalizas disminuye el riesgo CV, lo que ha causado interés en conocer los compuestos bioactivos y los mecanismos involucrados. Entre los componentes que protegen el endotelio se encuentran las moléculas antioxidantes (vitamina C, vitamina E y polifenoles) y ácidos grasos poliinsaturados. Las vitaminas C y E favorecen la vasodilatación protegiendo el NO al bloquear las especies reactivas del oxigeno (ROS). Los polifenoles mejoran la función endotelial principalmente por el aumento de los niveles de NO, y la inhibición de la angiogénesis y de la activación plaquetaria. Dietas ricas en ácidos grasos poliinsaturados han mostrado efectos beneficiosos, mediante la reducción de la expresión géni-ca de la ciclooxigenasa-2 y de la expresión de moléculas de adhesión celular. Esta revisión principalmente señala los conocimientos actuales de la disfunción endotelial y el efecto protector de las células endoteliales por componentes bioactivos de frutas y hortalizas.

Cardiovascular diseases (CVD) are the main cause of mortality worldwide. To prevent CVD it is recommended to quit smoking, the practice of physical activity and the consumption of healthy food. In this context, numerous studies have shown the importance of frequent consumption of fruits and vegetables (at least5 a day). It has been described an inverse relationship between vegetables consumption and the risk of developing CVD, which is mainly explained by its antioxidant activity, and in some cases lipid-lowering and platelet effects. In this sense, the increase in regular consumption of tomato (Solanum lycopersicum L.) and related products, can improve the some cardiovascular parameters. The current lifestyle favors the consumption of processed foods, a situation that may affect the stability of tomato components and their physicochemical properties. This review addresses the antioxidant activities, lipid-lowering and antiaggregant properties of tomato, as well as the effect of processing and storage. Additionally, a summary of some patents associated with beneficial effects on health. As bibliographic source www.pubmed.org was mainly used, the terms used in the search were and platelet, tomato, and platelet, antioxidant, among others, then search the full texts of items of common interest.
Las enfermedades cardiovasculares (ECV) son la principal causa de muerte en el mundo. En su prevención tiene mucha importancia el no fumar, realizar actividad física y consumir alimentos saludables. En este contexto, numerosos estudios han demostrado la importancia del consumo frecuente de frutas y hortalizas (al menos 5 porciones al día). Se ha descrito una relación inversa entre su ingesta y el riesgo de desarrollar ECV, lo que se explica principalmente por su actividad antioxidante, hipolipemiante y en algunos casos antiplaquetaria. En ese sentido aumentar el consumo actual de tomate (Solanum lycopersicum L.) y productos del tomate, puede mejorar algunos parámetros cardiovasculares. El actual estilo de vida induce a las personas a consumir alimentos procesados, lo que podría afectar la estabilidad de sus componentes y sus propiedades fisicoquímicas. Esta revisión aborda la actividad antioxidante, hipolipemiante y antiagregante plaquetaria del tomate, como también el efecto que tiene el procesamiento y almacenaje sobre dichas actividades. Adicionalmente se resumen algunas patentes asociadas a efectos beneficiosos en la salud. Como fuentes bibliográficas se utilizó principalmente www.pubmed.org; los términos utilizados en la búsqueda fueron: antiplatelet, tomato, platelet, antioxidant, entre otros; luego se buscaron los textos completos de los artículos que interesaban.
