Our latest issue (Jul/Set 2019) is fully available in Scielo with several articles on a range of different topics. It features 18 articles and many of them are also available in English and Spanish. In the Editor’s Note, André Felipe Cândido da Silva analyses the changes in scientific publishing, such as preprinting and open science. These changes were among the main topics discussed in the workshop held in June at Fiocruz to celebrate 25 years of our journal.
