It is a written report that communicates for the first time the results of a scientific investigation with a quantitative, qualitative, or mixed approach; It must contain sufficient and available information so that the results can be assessed and reproduced.

• Authors: up to six.
• Maximum length: 5,000 words, not including bibliographical references.
• Bibliographic references: up to 30.
• Tables, figures or graphs: up to six.

These works will have the following structure: structured abstract, keywords, introduction, methods, results, discussion, conclusions and bibliographical references. Between figures and tables, a maximum of six will be accepted.

Title: brief, understandable, informative and in correspondence with the objective of the article. It should not include acronyms, abbreviations, chemical formulas or proprietary names. Avoid interrogative titles, matches with punctuation marks and serial titles.

Abstract: it must be written in Spanish and English, in impersonal style and past tense, with an extension of no more than 250 words and three to 10 keywords. It must be structured in: introduction, objective, methods, results and conclusions. It should not contain abbreviations or acronyms. The keywords will be obtained from the Descriptors in Health Sciences (DeCS). In addition, the MeSH (Medical Subject Headings) can be consulted for the English language. http://www.ncbi.nlm.nih.gov/mesh

Introduction: it will be written in the present tense. It must show the published background that briefly substantiates the work done. It will describe how the subject is situated in previous science and in the international, national, municipal and local contexts. In addition, it must explain its relevance (reference is made to the general scientific and research problem) and justification for carrying out the study, and it will include a last paragraph where its main objective is clearly stated. It should not contain tables or figures.

Methods: they must be written in the past tense; The type of investigation or study, period of duration and place where it was carried out will be expressed. The criteria that characterize the subjects under investigation, the selection of the population, the inclusion, exclusion and exit criteria will be described, as well as the justification for the selection of the sample if necessary and the type of sampling used.

The variables analyzed must be clearly described. It must contain the way and sources of data collection and the procedure followed with the main techniques, including statistics. The classifications, algorithms, flowcharts or other types of scientific contributions from other authors that are used in the research must be duly referenced following the Vancouver style.

Statistical methods should be described in sufficient detail to allow verification of results from the data, report indicators of measurement error or uncertainty (such as confidence intervals), and avoid relying only on statistical hypothesis testing, such as the use of p values, which do not give information about the magnitude of the effect. The computer programs used and their version must be specified.

For more information on the selection and correct reporting of statistical methods, see the Statistical Analyzes and Methods in the Published Literature (SAMPL) Guidelines.

At the end, it must be declared, in detail, how the particular ethical aspects for the study were fulfilled.

This section must provide sufficient information so that the research can be reproduced by another author if necessary.

Results: they will be written in past tense, with the complement of tables and figures. The results must be in correspondence with the objective of the work and the research methods applied. They will be described with a logical sequence of text, tables and figures. The same information from tables and graphs must not be duplicated in the text.

Discussion: it constitutes a separate section of the results. It must contain a critical review of the study results in light of the works published in the literature on the subject and highlight the novel aspects. Explain in the paragraph prior to the conclusions the scope and limitations of the study, taking into account possible sources of bias or imprecision and their influence on the results, as well as the possible applicability and generalizability of the results.

Conclusions: they are written in past tense. They must originate in the work itself, as statements derived from the study carried out and coincide with the objectives of the research. They should not be a simple repetition of the results, but legitimate elaborations of the authors, built from the most important implications, of the findings identified in the study and where the contribution made to science is declared.
