RESUMO
We analyze 6 months of Twitter conversations related to the Chilean Covid-19 vaccination process, in order to understand the online forces that argue for or against it and suggest effective digital communication strategies. Using AI, we classify accounts into four categories that emerge from the data as a result of the type of language used. This classification naturally distinguishes pro- and anti-vaccine activists from moderates that promote or inhibit vaccination in discussions, which also play a key role that should be addressed by public policies. We find that all categories display relatively constant opinions, but that the number of tweeting accounts grows in each category during controversial periods. We also find that accounts disfavoring vaccination tend to appear in the periphery of the interaction network, which is consistent with Chile's high immunization levels. However, these are more active in addressing those favoring vaccination than vice-versa, revealing a potential communication problem even in a society where the antivaccine movement has no central role. Our results highlight the importance of social network analysis to understand public discussions and suggest online interventions that can help achieve successful immunization campaigns.

Se evaluó retrospectivamente la eficacia de la embolización arterial bronquial en el tratamiento de la hemoptisis masiva. El procedimiento se efectuo en 16 pacientes (12 hombres y 4 mujeres de 16 a 66 años de edad) que ingresaron al INERyCT con el diagnóstico de hemoptisis masiva entre 1982 y 1986. La embolización arterial bronquial se practicó en 11 enfermos con hemorragia activa. En 9 de ellos el procedimiento controló la hemorragia en le curso de una semana. Los dos pacientes restantes murieron por recurrencia de la hemorragia. En otra serie cinco pacientes fueron embolizados sin hemorragia activa. Un período de 13 meses de seguimiento en los 14 pacientes en que se realizó embolización arterial bronquial demostró éxito del tratamiento en 11 enfermos y fracaso (recurrencia de la hemorragia) en tres de ellos. Estos resultados coinciden con estudios realizados con mayor número de enfermos en otros países y permiten señalar que la embolización arterial bronquial es una alternativa eficaz de tratamiento en pacientes con hemoptsis masiva y la única alternativa en enfermos con contraindicaciones quirúrgica
