Background: Contact investigation is cardinal in the control of tuberculosis (TB) since it helps to stop its transmission. In Chile, the National TB Program strategy does not include latent TB infection testing, regular chemoprophylaxis or follow-up in adults. Active TB was found in only 1.2% of contacts at country-level during 2018. Aim: To evaluate the performance of a systematic screening of adult household contacts with targeted chemoprophylaxis and prolonged active follow-up. Material and Methods: Prospective cohort of household contacts in Santiago. Two face-to-face visits (at 0 and 12 weeks) that included QuantiFERON TB-Gold plus tests (QFT), chest radiography (CXR) at 0 and 24 weeks and, periodic text messaging or phone call follow-up for up to 48 weeks were implemented. Contacts with positive QFT were referred for TB chemoprophylaxis. Results: A total of 200 contacts were enrolled, 69% were migrants. At baseline evaluation, 45% had a positive QFT result and 1.6% had co-prevalent active TB. At follow-up, 13% contacts further converted to QFT (+), and 5.1% more were diagnosed with active TB (mean follow-up time 32 weeks). Of these 10 further active TB cases, 6 (60%) had a negative QFT and all (100%) had normal CXR at baseline; while three cases occurred in QFT converters. Conclusions: In this cohort of household contacts, 6.7 % were diagnosed with active TB (more than 2/3 at follow-up) and 13% had a late QFT (+) conversion. Active and prolonged contacts' follow-up are essential to detect new infections and tackle the TB epidemic in Chile.

Em sentido oposto à crença segundo a qual Volpi seria um artista intuitivo, este artigo sustenta que o artista chegou às soluções de sua obra a partir de uma incorporação peculiar de toda a tradição moderna. O artigo mostra ainda como a experiência de Volpi com as discussões levantadas por concretos e neoconcretos contribuiu para suas novas articulações formais, ainda que com soluções bem distantes daquelas encontradas pelos artistas dos dois grupos.

In the opposite direction of the belief according to which Volpi would be an intuitive artist, this article states that the artist found the solutions of his work after a peculiar assimilation of the modern tradition. The article shows how Volpi's experience with discussions raised by concrete and neoconcrete artists helped shape his formal articulations, even though with solutions quite different from those of the artists of both groups.
