We cannot deny the popularity of films of explicit sex in our society nowadays. They are seen in a negative and degrading way by some, whilst others see them with some ease and without many restrictions. The fact is that issues involving human sexuality are taboo, and became taboo because of subjects and discourses that circulate in our society and history. Because they generate controversy, these issues are often approached by many forms of media. Among them, we mention Superinteressante Magazine, which in January 2011 published an article called Porn is good for society, written by Milton Diamond. We propose, with this work, to analyze the text using Pcheuxs Discourse Analyzes, aiming to show how the ideologies cross the discourse of the subject in spite of his/her identification with a particular discursive formation. For this, we use assumptions of Michel Pcheux (1995), Eni Orlandi (2003, 2007) and Denise Maldidier (2003), using concepts such as production conditions, subject, discourse, discursive formation, among others, in order to make evident the different effects of meaning and the representations of the collective imagination, which can be understood through the discursive materiality.

It is well documented that Chagas disease (CD) can pose a public health problem to countries. As one of the World Health Organization Neglected Tropical Diseases undoubtedly calls for comprehensive healthcare, transcending a restricted biomedical approach. After more than a century since their discovery, in 1909, people affected by CD are still frequently marginalised and/or neglected. The aim of this article is to tell the story of their activism, highlighting key historical experiences and successful initiatives, from 1909 to 2019. The first association was created in 1987, in the city of Recife, Brazil. So far, thirty associations have been reported on five continents. They were created as independent non-profit civil society organisations and run democratically by affected people. Among the common associations' objectives, we notably find: increase the visibility of the affected; make their voice heard; build bridges between patients, health system professionals, public health officials, policy makers and the academic and scientific communities. The International Federation of Associations of People Affected by CD - FINDECHAGAS, created in 2010 with the input of the Americas, Europe and the Western Pacific, counts as one of the main responses to the globalisation of CD. Despite all the obstacles and difficulties encountered, the Federation has thrived, grown, and matured. As a result of this mobilisation along with the support of many national and international partners, in May 2019 the 72nd World Health Assembly decided to establish World Chagas Disease Day, on 14 April. The associative movement has increased the understanding of the challenges related to the disease and breaks the silence around Chagas disease, improving surveillance, and sustaining engagement towards the United Nations 2030 agenda.
