It should state the primary objective of the review, the principal reasoning for the procedures adopted, the main results of the referred studies, and the conclusions that can be drawn from the data available. Numerical data may be included, but should be kept to a minimum.



The abstract should be followed by a list of 3-5 keywords, which will assist in the crossindexing of the article. The terms used should be from the Medical Subject Headings list of the Index Medicus.



Full papers should be divided into sections at the convenience of the author, but should include an Introduction and a Conclusion.

References to figures and tables should be made in order of appearance in the text and should be in Arabic numerals in parentheses, e.g. (Fig. 2). Figures should be professionally drawn and photographed; freehand or typewritten lettering is unacceptable. Photomicrographs must have internal scale markers. If photographs of people are used, their identities must be obscured or the picture must be accompanied by written permission of the subject to use the photograph.

If a previously published figure is used, the original source must be acknowledged and written permission for print and electronic (internet and CD-ROM) formats from the copyright holder must be submitted with the material.

The editorial process consists of 6 stages:

1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.

2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.

3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.

4. Editorial review (maximum 7 business days): its objective is to make a decision based on the opinion of peer reviewers. The opinion can be rejected, major changes, minor changes or accepted. In the case of major or minor changes, it will be submitted again for evaluation by the initial peer reviewers.

5. Final edition (6 weeks): its objective is the technical and linguistic edition (and translation), layout of galleys, DOI assignment, and correction by the author.

6. Advanced publication: All manuscripts will be published ahead of print on the journal's website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.



The corresponding author will receive proofs of the article for revision and correction of terminology errors, or any other updates related to facts/figures. As the article will already have been edited according to the journal’s internal editorial guidelines, style corrections will not be accepted. The corresponding author will receive an email with the article in PDF format, on which they can leave their comments. Authors will need to have Adobe Reader (version 9, or a later version), downloadable for free). For other system requirements, please visit the Adobe website.

Alternatively, authors may list their corrections and submit them via email. Any major changes at this stage will be subject to the approval of the Editor. Authors should make sure to include all changes in a single email, as we cannot guarantee the inclusion of subsequent corrections.

The proof review is the responsibility of the author.
