In exceptional cases where this is permitted, it is mandatory to obtain the written consent of the authors whose names are to be removed from or added to the manuscript. In addition, a signed statement must be sent stating that all authors meet the authorship criteria and that there are no other authors who, meeting the criteria, have been omitted, and mention again in detail the contribution of each person to the research and to the manuscript.

Evaluations. All the articles received will be reviewed in the first instance by the editorial coordination, in order to verify the thematic relevance, their originality and compliance with the publication standards already established. In case of positive qualification, a bibliographic review will be carried out according to the Vancouver Standards and detection of text similarity through software before sending them to the reviewers. If a manuscript has more than 20% text similarity based on the verification result, it is returned to the author.Once the formal aspects have been verified, the article that get into the review process will be sent for evaluation by a Scientific Committee, made up of national and international academic peers, safeguarding the authors' data in order to guarantee blind review. The blind peers will issue a report based on the following possible opinions:• Accepted: Article suitable for publication, without requiring modifications, or with minimal modifications• Accepted based on the suggested modifications: The indicated corrections must be made and the work submitted for a new review.• Rejected: The article does not conform to the theme, policy and / or norms of the journal, or substantial adjustments must be made in the writing.
