En el campamento de los yanquis se ha producido un tiroteoA Dionisio Romero le han acribillado a balazos en este poblado de infraviviendas a las afueras de Madrid. Todos los vecinos saben que la cosa no va a acabar así, que en ese lugar la sangre se lava con más sangre. Y lo primero que se encuentra Javier Valenzuela al llegar al lugar de los hechos es a un chaval de 14 años que busca un cigarrillo para liarse un canuto y que palmea por bulerías. A partir de ese encuentro, el periodista reconstruye las formas de vida en el campamento de los yanquis, escenario de una de estas crónicas.Las cond

Se realizó el análisis de la investigación mexicana en salud indizada en MEDLINE en un periodo de 15 años (1987-2001) con el objetivo de obtener su panorama e impacto en el entorno internacional. Los resultados obtenidos mostraron que la ciencia mexicana en salud mantiene un ritmo de crecimiento constante en el periodo estudiado, y que la mayor generación de artículos científicos ha salido de las universidades, principalmente la UNAM, y de los Institutos de Salud gubernamentales. Al mismo tiempo, el mayor impacto internacional lo han conseguido los trabajos de investigación en salud elaborados por la UNAM, y se identificó la centralización de la investigación en pocas regiones del país, situación que ya ha sido reportada en otros estudios similares. Así mismo, la bioquímica, las neurociencias y la farmacología fueron las disciplinas que mayor número de citas obtuvieron ; We analyzed the Mexican research in Health Sciences included in MEDLINE, between the period of 1987-2001. The objective was to know its international impact. Results showed that there is a constant growth in the studied period, and that most of scientific articles has been written in universities institutions, mainly the UNAM, and in government Institutes of Health. The greater international impact was obtained by papers elaborated by UNAM researchers, and the centralization of the investigation in few regions of the country was identified. Also, the biochemistry, the neurociencias and the pharmacology were the disciplines with a greater number of received cites.

Most road accidents in Chile (causing about 1,600 deaths per year) are linked to speeding. A widely used control mechanism all over the world, the speed detectors, enabled in the middle of the 1990's was then suddenly prohibited in Chile through the enactment of a law justified on the idea that radars were only used to raise funds to local governments and in some way, a source of illegal profits. This paper studies the causes and consequences of this law. In particular, it attempts to verify whether the evidence is more consistent with the hypothesis that speed detectors radars were used as cazabobos or, on the contrary, they were effective reducing accidents and their consequences. We conclude that the evidence is consistent with the second hypothesis, so that such a law caused important social costs. Depending on the life valuation method considered, and projecting the evidence of some road areas to only two Santiago districts, we conclude that the cost of the law ranges between US$83 and US$ 600 millions in present value for those districts. The effect of a widely applied speed detector program is expected to be much more convenient. ; La mayoría de los 1.600 muertos anuales por accidentes de tránsito en Chile se relaciona con el exceso de velocidad. Una herramienta de control de velocidad, el fotorradar, puesta en uso a mediados de la década de 1990, fue abrupta y prácticamente prohibida por una ley que se promulgó sobre la base de que ellos "eran cazabobos", es decir, eran usados básicamente para incrementar los ingresos de privados y municipios y no para reducir los accidentes. El objetivo de este trabajo es analizar las causas y consecuencias de la eliminación del uso de fotorradares en Chile. En particular, se desea contrastar si la evidencia es más consistente con la hipótesis de que los fotorradares fueron usados como cazabobos, o por el contrario, constituían una herramienta de prevención y reducción de accidentes. Concluimos que la evidencia es más consistente con la segunda hipótesis, y que el ...

Non-communicable diseases, particularly cardiovascular diseases, are the leading cause of decreased life expectancy and death in Latin America and the Caribbean. Although a lifestyle, which includes no tobacco use, good nutrition, and regular physical activity is touted as key to health, the environmental, racial, social and economic conditions, which underpin lifestyle are often ignored or considered only secondarily. Placing the main responsibility on a patient to change their lifestyle or to simply comply with pharmacological treatment ignores the specific conditions in which the individual lives. Furthermore, there are major disparities in access to both healthy living conditions as well as access to medical care.There is sufficient evidence to support advocating for policies that support healthy living, particularly healthy food choices. Progress is being made to improve the food environment with enactment of front of package nutritional labels. However, policies were enacted only after intense regional research and advocacy supporting their implementation.Government officials must rise above the pressures of commercial interests and support health-promoting policies or be exposed as self-interest groups themselves. Strong advocacy is required to persuade officials that all policies should take health into consideration both to improve lives and economies.
