Guidelines for authors
Common requirements for all types of articles
Articles will be submitted exclusively through the journal's online management system (https://www.revmediciego.sld.cu)
Originality: the works must be up-to-date and innovative. If they have been previously made public, the author has the duty to communicate this.
Writing: the document submitted must be written correctly, clearly, coherently, with adequate syntax and good spelling. The meaning of the abbreviations, acronyms and symbols used must be described. The use of these must not be excessive.
Manuscript submission forms: all articles must be written in Spanish using Times New Roman font, 12 points, two-centimeter margins, and 1.5 line spacing. Compressed files of any format are not accepted.
Title: no more than 15 words. In Spanish and English. Must not include acronyms or abbreviations.
Authors: full names, two surnames, and each author's email address must appear. Avoid initials. The main author must provide his or her telephone number.
Each author must be included on a separate line with his/her professional title, scientific degrees, academic degrees, teaching and research categories, and institutional affiliation (university and faculty to which he/she is linked as a part-time or full-time professor, then the institution in which he/she works, the vice-director and the department to which he/she belongs). The names of the institutions must be official and up-to-date.
The ORCID digital identifier (https://orcid.org/ ) of each of the authors must be included, and its authenticity and updating will be verified.
At the end of the text of the article, before the bibliographical references, the contributions of the authors must be declared. To do so, the taxonomy of the contributor's roles included in the declaration of authorship and originality that accompanies the submission will be used (https://credit-niso-org.translate.goog/?_x_tr_sl=en&_x_tr_tl=es&_x_tr_hl=es&_x_tr_pto=tc/).
Unwarranted authorship is called into question when people without a significant contribution to the work are included. When authors need to acknowledge other people who contributed to the work but whose contribution does not justify their authorship, they are encouraged to include an acknowledgements section at the end of the work, where they are mentioned. A statement that each person mentioned authorizes being mentioned should be sent.
Authors are encouraged to provide primary records of the data used for publication with the article.
In the manuscript, authors must explicitly declare whether or not their work involves a conflict of interest and express the approval of the Scientific Council and the Research Ethics Committee of their institution.
Bibliographic references: This journal complies with the requirements established by the International Committee of Biomedical Journal Editors (Vancouver style): https://www.ncbi.nlm.nih.gov/books/NBK7256/pdf/Bookshelf_NBK7256.pdf
Citations from relevant sources published in the last five years will be included (75% for original articles, 70% for review articles, and 50% for case reports); national and international literature will be represented. Mention of personal communications and unpublished documents should be avoided, unless they provide essential information not available in public sources, in which case the name of the person providing the information and the date of the communication should be cited in parentheses in the text.
All authors of the cited text must be listed (if there are seven or more authors, the first six must be listed, followed by et al.). Journal titles must be abbreviated using the Index Medicus. For titles not listed in the Index Medicus, the NLM Catalogue (journals referenced in the NCBI databases), the journal abbreviation entries in PubMed and MEDLINE, and the ISI Journal Abbreviation Index (exclusive list of abbreviations for periodical publications) may be consulted.
Attention must be paid to the order of bibliographic elements and the use of punctuation marks prescribed by the style. The electronic addresses (URL) of references to documents on the Internet must always correspond to the full text and not just to the abstract.
Figures and tables: tables, graphs and diagrams in JPG format are not accepted; they must be submitted in an editable format. All figures must be of adequate quality and must not exceed 800 pixels in width. Photographs must be submitted in JPG format (300 dpi).
Each table must be included in the text of the article, exactly where it is cited; they must be numbered consecutively according to the order in which they are presented and identified with a brief title. Authors must ensure that each table is appropriately referenced in the text. If data from other sources, published or not, are presented in the tables, the sources in question must be publicly acknowledged.
Tables should be laid out in a simple (standard) grid, and each column should contain an abbreviated header and a legend. Explanations should be included in table footnotes, not in titles or headings. All unusual abbreviations should be explained in table footnotes. The following symbols should be used, in the same order as presented: *, †, ‡, §, ||, ¶, **, ††, ‡‡
Statistical measures of dispersion, such as the standard deviation or standard error of the mean, must be properly identified. Decimal numbers should be separated by commas, not periods.
Figures should be of professional quality and should be submitted in a format that allows high-quality image reproduction (e.g. JPG, PNG or GIF). Authors should check these images on their computer and verify that they meet the necessary quality requirements before submission.
In the case of X-rays, ultrasounds and other diagnostic imaging techniques, as well as photographs of pathological specimens or micrographs, photographic reproductions with a size of 127 × 173 mm will be used. Letters, numbers and symbols included in the figures must be clear and uniform, as well as of sufficient size so that they remain legible in the reduced version of the article once published. Figures should be self-explanatory as much as possible, since many will be reproduced directly as slides for scientific presentations, however, titles and detailed explanations should be included in legends, not in the body of the figures.
Photomicrographs must contain scale markers. Symbols, arrows or letters included in the photomicrographs must stand out clearly against the background; the meanings of all of them must be clearly explained in the legend. If photographs of people are used, they should not be identifiable or they should be accompanied by appropriate written permission to use them. Where possible, specific permission should be obtained for publication of these materials. The internal scale of the image should also be explained and the staining method used described.
The graphs must be drawn in color (on a white background) and with their corresponding legend. The data reflected in the body of the graph must be duly highlighted against its colors, so that they can be correctly viewed.
Each figure will be included in the text of the article, exactly where it is cited, and will be numbered consecutively according to the order of presentation. If a previously published figure is used, the original source must be identified. The legends of the illustrations will be placed at the bottom of them.
Units of measurement: Metric units (meters, kilograms, or liters) or their decimal multiples should be used for measurements of length, height, weight, and volume. Temperature should be expressed in degrees Celsius. Blood pressure should be measured in millimeters of mercury (mm Hg), unless the journal specifically requests the use of other units.
The results of clinical laboratory tests shall be reported according to the International System of Units. If it is necessary to use traditional units, they shall be written in parentheses. Example: blood glucose: 5.55 mmol/L (100 mg/%/100 ml).
Clinical trials: must bear the registration number obtained in a National Registry of Clinical Trials (https://rpcec.sld.cu/). This number must be verifiable, so the source will appear. In addition, the manuscript must conform to the evaluation parameters established in the international CONSORT guide: https://www.equator-network.org/reporting-guidelines/consort/
Ethical considerations: the research presented must comply with all ethical declarations for the types of studies, whether in humans or animals (Declaration of Helsinki) duly referenced. https://cnrha.sanidad.gob.es/documentacion/bioetica/pdf/Helsinki.pdf
