Author Guidelines
General : Manuscripts should not not more than 5000-6000 words (not including abstract), should be submitted in English, in Calibri font size 12
Title: It must briefly and concisely indicate the contents of the manu-script and it has to provide the maximum information with the minimum number of words (it recommended not to exceed 15). It must not include acronyms. A short title should be included with a maximum of 80 characters with spaces.
Abstract and Keywords: For Original and Short Original works, it has to be structured into the following sections: Objective, Method, Results (most important 3-4) and Conclusion (1-2, arising from the results). It should contain sufficient information for the reader to have a clear idea of the contents of the manuscript. It should not contain information that cannot be found later in the manuscript. On the same page it will give between 3 and 6 keywords, directly related to the topic presented in the manuscript. MeSH terms (Medical Subject Headings) should be used or the Health Sciences Descriptors (Decs) so that they can be classified in the international data bases. A Spanish and English version of the abstract and keywords must be submitted.
Text or body of the manuscript: It is advisable to divide the work clearly into sections, depending on the section to which it may be submitted: Originals and Short Originals: Introduction, Method, Results, and Discussion.
Introduction: The introduction should include the definition of the basic concepts, contextualize the topic of study, justify its relevance and expose the current state of the topic. In the last part the objectives of the study will be defined. It will be as brief as possible, and its basic rule is to provide the basic information necessary for the reader to be able to understand the text that follows later. All of this supported with the most current and important literature references.
Method: An exhaustive description must be provided on how the study has been performed, with sufficient information so that other researchers can replicate it; that is, that they can perform it without consulting the authors. Its content will be determined by the objectives of the study. It will contain several sub-sections that do not need to be specified in the text:
Design:The type of study performed must be mentioned, justifying, if necessary, the reasons for its choice.
Population and Study Setting:Indicate the place and the date of performing the study. Specify the characteristics of the studied population and the inclusion and exclusion criteria. If all the population has not been studied, it must indicate how the sample size was calculated and the value of the parameters used, as well as the sampling technique.
Variables: Define all the variables that have been collected, determined by the objectives established, particularly the variables of the most important results. If it is an experimental study, it must mention the intervention made (also of the control group, if relevant and the follow-up time.
Data collection: Explain how the data have been collected and who did it, as well as the tools used for this purpose, indicating if they are validated and the corresponding literature reference.
Data Analysis:Mention the statistics program used for the analysis and the analysis performed. Indicate the strategy used for the literature review, that is, data bases reviewed, the descriptors or keywords employed in the search and the years reviewed.
Results: It must only include the most important results, according to the objectives and the statistical analysis mentioned in the Method section. The results must respond exactly to the objectives that have been established and must make clear whether or not they certify the working hypothesis. There should not be any objective in the introduction that is not given a response in the results and any objective not mentioned in the introduction should not have a response in the results. Assessments or comments on the results obtained should also not be included in this section.
Discussion: In this section, the authors must express their opinions on study topic and the results obtained, avoiding repetition of the information that has been given in the Results or in the Introduction. Comparison should be made with the results obtained in other studies, with the corresponding literature references. Mention should be made of the possible limitations of the study that could determine the interpretation of the results. The conclusions and the appropriate recommendations will be reflected, as well as suggestions for future studies on the topic and the implications that it has for the practice. The Discussion, as in the Conclusions, must arise directly from the results, and comments or statements that are not associated with the results obtained in the study must be avoided. It should also take into account, that although statistically significant differences are found in the hypothesis contrasts, these differences may not be relevant in clinical practice and, therefore, there should be caution when interpreting them. In the discussion should include the limitations of the study and finalize the conclusions within this same section, without indicating a specific heading for it.
Bibliography: The adapting of the literature references to the Vancouver Style and their accuracy are the responsibility of the authors, therefore it is advised to make an exhaustive review of these and check them with the original documents, so that they do not contain errors that could hinder locating them by interested readers. The literature reference must be consecutively numbered using Arabic numbers in superscript according to their appearance in the text for the first time. When they coincide with a punctuation sign, the citation will always precede that sign. It is recommended that the bibliographic references included should not be more than 10 years old, and that at least half of them be less than 5 years old, including references from prestigious journals
Conflict of Interest, It explains a situation in which a person or organization is involved in multiple interests, financial or otherwise, and serving one interest could involve working against another. Typically, this relates to situations in which the personal interest of an individual or organization might adversely affect a duty owed to make decisions for the benefit of a third party.

List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Formatting of funding sources, List funding sources in this standard way to facilitate compliance to funder's requirements: Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].
Ethical Aspects: It must be specified, in the case of research studies, whether it has been approved by the corresponding Ethics Committee, and whether it complies with the requirement estab-lished in national and international guidelines for clinical trials and similar studies as applicable.
