The Journal April 16 for the acceptance and publication of scientific articles related to the sciences of health is governed by the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, created by the Vancouver group, with some specifications due to the editorial interests of our publication. The journal is mainly aimed at the publication of research developed by undergraduate students and residents of any of the biomedical careers, although it has a section especially dedicated to the publication of scientific articles written by professors.

Submitted manuscripts may be unpublished, or in preprints version and may not have been sent to another journal simultaneously and once accepted by this publication, the Journal 16 de Abril assumes the editorial rights over them. The journal is fully open access so that all articles will be immediately and permanently accessible to facilitate reading and downloading.

The journal also has other types: Special articles and Opinion articles. In addition, summaries of student scientific events are published, as well as any contribution that the Editorial Committee considers of interest for publication.

The potential conflict of interest exists regardless of whether the interested parties consider that said relationships influence their scientific judgment or not. The authors will describe the existence or not of conflicts of interest after the conclusions of the manuscript.

Definition of Authorship

According to the International Committee of Medical Journal Editors, an author is considered to be one who meets the following conditions:

1. Substantial contribution in the conception and design of the work; or the acquisition, analysis and interpretation of the data.

2. Design or critical review of important parts of the intellectual content.

3. Approval of the final version of the manuscript.

4. Take responsibility for all aspects of the manuscript, to ensure that issues related to the accuracy or completeness of any part of it are properly investigated and resolved.

All those who do not meet the 4 previous criteria will be considered as contributors and will be mentioned in the acknowledgments section (eg tutors, institution authorities).

Added to this and in In correspondence with suggestions from the Editorial de Ciencias Médicas (ECIMED), the authors must declare in each article their contribution according to the CRediT taxonomy (Taxon of contributor roles). is a high-level taxonomy, including 14 roles, that can be used to represent the roles that contributors typically play in scientific academic output. The roles describe the specific contribution of each contributor to academic production. It must be consulted at https://casrai.org/credit/ < / a>. The declaration of authorship must appear after the conflict of interest section.

Funding Sources

The editorial committee demands for the publication of a scientific article regardless of its type, that its authors declare the sources of funding they received for its preparation.

SUBMISSION OF MANUSCRIPTS

Manuscripts must be submitted through the web page http://www.rev16deabril.sld.cu/index.php/16_04, where you will find the necessary information to make the submission. The use of this resource allows to follow the state of the manuscript through the web page.

Opening the data

for which they have a maximum of 15 days. The extension of the term may be cause for rejection mainly, due to the loss of validity of the selected topic, its relevance or the timeliness of its citations.

The accepted manuscripts do not necessarily have to be Unpublished, documents that have been previously deposited in recognized specialty preprint servers such as SciELO Preprints, PMC, Plos and MedRxiv are accepted. Accepted papers remain the property of the journal and, therefore, cannot be submitted to another journal for consideration for publication, except with the proper authorization of the journal's Editorial Committee. However, as Journal 16 de Abril adheres to the policy of open access to scientific publication, allows their copying and distribution as long as you maintain the recognition of their authors, do not make commercial use of the works and do not make any modifications to them. The Editorial Committee reserves the right to introduce style modifications and / or limit the texts that require it, committing to respect the original content.

The Journal 16 de Abril does not contain, nor accepts advertising materials, is not responsible for the opinions or criteria of the authors, nor does it accept works that have been previously published or are under the consideration of the Editorial Board of another national or foreign journal. The publication rules can be consulted before submitting an article on-line in section policy.

The articles will be reviewed according to priority in the editorial mattress. This review will be carried out by two professional reviewers external to the publishing institution and / or the country, using the double-blind method, to guarantee the correct review of the same. It includes the evaluation of legality and authenticity of scientific articles.

In the same way, the Journal 16 de Abril is aligned with the principles of open science and allows the convenient use of peer arbitration practices open as a mechanism to promote transparency in the editorial process and scientific communication.

At the end of each analysis, the result of the review of the articles is decided, which can be:

Publishable: the article meets the required criteria and characteristics, so it can be publishable as is.

Publishable with modifications: the article meets almost all the required criteria and characteristics, for which it needs minimal corrections to be published. In this case, the corrections are made, the publisher is notified and it is decided if the errors have been solved. If the errors are solved, the work is accepted (Publishable), otherwise it is forwarded again to the author, until the errors are corrected.

Reevaluable: the article has errors or does not comply criteria and characteristics required, but these do not affect the quality and veracity of the publication. Corrections are sent to the author, which forwards the article to the journal, starting a second round of evaluation.

Not publishable: the article does not comply with the methodological and content standards, which threatens quality or veracity of the article.

Finally, the manuscript goes to the proofreader who checks and corrects all the spelling and grammatical errors.

The writing of the journal will keep the authors informed of the works received and their subsequent acceptance or not to continue in the process, and they will be able to know when they are in it. The manuscripts will be reviewed anonymously by two experts in the object of study and / or methodology used. The editorial board of the journal reserves the right to reject articles that it does not consider appropriate for publication. Editorial decisions are final.

Then they are layout and sent to the authors so that they, within a period of no more than 72 hours, approve the final version of the article in PDF that is going to be published. In case of no response from the authors, the manuscript will be considered accepted.
