We are going through a moment in which acts of disregard to the ethics in the public function are being disclosed at all levels. It is important to know the codes of ethics and good practices of each of the functions performed. In the field of scientific publications, it is highly recommended that all researchers who wish to publish their studies get to know the good scientific practices and the basic ethical principles of publications in science. The vast majority of medical journals are guided by the recommendations of the International Committee of Medical Journal Editors (ICMJE) and with respect to ethical shortcomings, by the guidelines of the COPE (Committee on Ethics in Publications). Frequent examples of scientific misconduct that can be found in local magazines are problems of authorship, redundant publication and plagiarism and lack of declaration of conflict of interest. In the present article we provide links to self-learning resources on these topics and we emphasize the importance of their wide dissemination.
