Proposals for the prevention of lung cancer in the health system of Mexico / Propuestas para la prevención de cáncer de pulmón en el sistema de salud en México

Abstract The management of lung cancer is challenging. However, nowadays the main goal is to achieve a significant overall survival accompanied by a good quality of life. Because smoking is associated with up to 71% of cancer deaths, the first policy that should be established is one that promotes strategies for healthy lifestyles by providing information about lung cancer, risk factors, protection factors, and precautionary data. Furthermore, an effective screening method that would allow early diagnosis should be established. Following diagnosis, the patient should be genotyped to identify predisposing mutations to give personalized medicine to the patient. The health system policies should include information that affects the health of the population and simultaneously allows for early diagnoses, resulting in a higher survival rate.

Resumen El manejo del cáncer de pulmón es un reto que tiene como objetivo una supervivencia global significativa que se vea rodeada de una buena calidad de vida. Si se considera que el tabaquismo está asociado hasta con 71% de las muertes por cáncer, la primera política que debe establecerse es la de proporcionar información sobre el cáncer de pulmón, factores de riesgo, factores de protección y datos de alarma mediante una estrategia de salud de línea de vida, además del establecimiento de un método de tamizaje efectivo que permita un diagnóstico temprano. Después del diagnóstico, debe realizarse una genotipificación para identificar mutaciones sensibles y para proporcionar un tratamiento personalizado al paciente. Las políticas del sistema de salud deben incluir información para que la población incida en su salud y también se puedan realizar diagnósticos tempranos que permitan una mayor supervivencia.

Current concepts on magnetic resonance imaging (MRI) perfusion-diffusion assessment in acute ischaemic stroke: a review & an update for the clinicians.

Recently, several medical societies published joint statements about imaging recommendations for acute stroke and transient ischaemic attack patients. In following with these published guidelines, we considered it appropriate to present a brief, practical and updated review of the most relevant concepts on the MRI assessment of acute stroke. Basic principles of the clinical interpretation of diffusion, perfusion, and MRI angiography (as part of a global MRI protocol) are discussed with accompanying images for each sequence. Brief comments on incidence and differential diagnosis are also included, together with limitations of the techniques and levels of evidence. The purpose of this article is to present knowledge that can be applied in day-to-day clinical practice in specialized stroke units or emergency rooms to attend patients with acute ischaemic stroke or transient ischaemic attack according to international standards.
