<p><strong>Introducción: </strong>Estimar la eficiencia de dos programas de actividad física sobre la NAFLD</p><p><strong>Métodos: </strong>Sujetos con NAFLD moderada o severa que habían participado a un estudio de pobación en el sur de Italia fueron invitados a participar. Fue completado un cuestionario, se tomaron medidas antropométricas y se realizó una ecografia hepática. Cada participante proveyó el consenso informato. Los participantes fueron aleatorizados a un programa aerobico (actividad aerobica moderada per 30 minutos, 5 veces a la semana) o un programa mixto (aerobico más entrenamiento de la fuerza de los grandes grupos musculares, 60 minutos, tres veces a la semana). Fue medida la adherencia a los programas y se aplicó un modelo linear mixto a los datos.</p><p><strong>Resultados: </strong>El programa aerobico tuvo muy buena adherencia y esta aumentó con el tiempo mientras el programa mixto tuvo 100% de adherencia. No hubo diferencias estadísticamente significativas en el score de NAFLD al enrolamiento, mientras hubo diferencias estadísticamente significativas en el score medio de NAFLD después de 6 meses pero el score en el grupo del programa aerobico tuvo una reducción del 22% más intensa que el programa mixto. Este último programa por lo tanto se ha mostrado menos efectivo que el programa aerobico.</p><p><strong>Conclusión: </strong>Un programa de actividad física aerobica es un tratamiento realístico que podría ser efectuado no solo para la NAFLD sino también como prevención primaria de otras enfermedades crónicas.</p>
The world faces an aging population that implies a large number of people affected with chronic diseases. Argentina has reached an advanced stage of demographic transition and presents a comparatively high rate of cancer mortality within Latin America. The objectives of this study were to examine cancer mortality trends in the province of Córdoba, Argentina, between 1986 and 2011, and to analyze the differences attributable to risk variations and demographic changes. Longitudinal series of age-standardized mortality rates for overall, breast and prostate cancers were modeled by Joinpoint regression to estimate the annual percent change. The Bashir & Estève method was used to split crude mortality rate variation into three components: mortality risk, population age structure and population size. A decreasing cancer age-standardized mortality rates trend was observed (1986-2011 annual percent change: -1.4, 95%CI: -1.6, -1.2 in men; -0.8, 95%CI: -1.0, -0.6 in women), with a significant shift in 1996. There were positive crude mortality rate net changes for overall female cancer, breast and prostate cancers, which were primarily attributable to demographic changes. Inversely, overall male cancer crude mortality rate showed a 9.15% decrease, mostly due to mortality risk. Despite favorable age-standardized mortality rates trends, the influence of population aging reinforces the challenge to control cancer in populations with an increasingly aged demographic structure.
A pro-inflammatory diet, reflected by higher DII scores, was positively associated with PrCA occurrence. Based on these results and those from other studies, steps should be taken to promote a diet rich in anti-inflammatory foods, in order to reduce risk of PrCA and other chronic diseases. Future studies should explore this association in a prospective setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
