Criteria. Research articles should report original primary research. Manuscripts should be 3000 to 5000 words in length and should have at least 15 references.

Essential title page information 

Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.

Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.

Corresponding author. The corresponding author should be indicated with an asterisk, who will handle correspondence at all stages of peer-review, publication, and post-publication.
Ensure that a telephone number (with country and area code) is provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding/contacting author.

Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

Abstract. The Abstract should not exceed 250 words. Please minimize the use of abbreviations and do not cite references in the abstract. The abstract shall appear in both English and Spanish.

Introduction. The introduction should supply sufficient background information to allow the reader to understand and evaluate the results of the present study without referring to previous publications on the topic. The introduction should also provide the hypothesis that was addressed or the rationale for the present study. Use only those references required to provide the most salient background rather than an exhaustive review of the topic.

Keywords. Authors must provide between three and six keywords, which should not be part of the title of the paper. Phrases and general or broad words, such as "pH" or "growth", are not allowed.

Abbreviations. Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Those abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.

Nomenclature and units. Follow internationally accepted rules and conventions: use the international system of units (SI) ( If other quantities are mentioned, give their equivalent in SI. Authors wishing to present a table of nomenclature should do so on the second page of their manuscript.

Math formulae. Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text) (for example: Equation 1).

Figures. The figures (photographs, drawings, and graphs) must be numbered with Arabic numerals. Footnotes can be included below the figure. Figures that include more than one image should be labelled as a, b, c, etc. (lower case, use black or white bold, according to the figure).

Tables. Tables must be numbered with Arabic numerals in the order in which they are cited in the text. They should have a brief descriptive title placed at the top. A short description is also accepted. Avoid vertical rules. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Tables must be sent in Microsoft Word and have no links to the main document or other archives. Provide files at approximately the correct size they are to be printed (letter size). When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns.

Materials and Methods. The Materials and Methods section should include sufficient technical information to allow the experiments to be repeated.

Results. This section should describe the findings of the study, including, if appropriate, results of statistical analyses, which must be included in either the text or tables and figures. All results obtained shall be accompanied by the minimum number of graphs, tables, figures, or monograms strictly necessary.  These shall be located in the corresponding place within the text and shall be of a size that is considered necessary for their understanding and analysis.

Discussion. For research articles, this section should discuss the implications of the findings in the context of existing research and highlight limitations of the study.  It shall be limited to original and other data related directly to the results that are considered new.

Conclusions. This section should state clearly the main conclusions and provide an explanation of the importance and relevance of the study to the field.

Funding. All sources of funding for the research reported should be declared. The role of the funding body in the design of the study and collection, analysis, and interpretation of data and in writing the manuscript should be declared.

Acknowledgements. Please acknowledge anyone who contributed towards the article who does not meet the criteria for authorship, including anyone who provided professional writing services or materials.

References. All references, including URLs, must be numbered in sequential order parenthetically by number, in the order in which they are cited in the article, followed by any in tables or legends. The reference numbers must be complete and coincide with those in the reference list, which must be fully formatted before submission. The DOI or ISBN numbers must be included also at the end of each reference. Please provide the article's Digital Object Identifier (DOI) at the end of each reference in the following format: e.g.

The names of all the authors and/or editors for each reference must be provided; long bylines should not be abbreviated with “et al.” All listed references must be cited in the text. Abbreviate journal names according to the PubMed Journals Database

Citation in text. Please ensure that every reference cited in the text is also present in the reference list (and vice versa).  Unpublished results, personal communications, and theses are allowed, but only when strictly necessary and should be cited in the narrative. Citation of a reference as "in press" implies that the paper has been accepted for publication.

Web references. As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Review articles are an attempt by one or more authors to sum up the current state of the research on a particular topic. Ideally, the author searches for everything relevant to the topic, and then sorts it all out into a coherent view of the "state of the art" as it now stands. Review articles should have at least 30 references and they should have between 3500 and 6000 words.

Review articles should inform about:

  • The main researchers working in a field
  • Recent major advances and discoveries
  • Significant gaps in the research
  • Current debates
  • Future directions

They include essential title page information, an abstract, keywords, abbreviations (if necessary), an introduction that outlines the main theme, brief subheadings, and an outline of important unresolved questions.

Only review articles from experts in the field will be considered for publication.

Subdivision - numbered sections. Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, 1.1.3, …), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to "the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line.

Criteria. The Short communication format is intended for the presentation of brief observations that do not warrant full-length papers. However, Short communication papers should contain firm data. Submit Short communication papers in the same way as full-length papers. They receive the same review, they are not published more rapidly than full-length papers, and they are not considered preliminary communications. Short communications are also suitable for the presentation of research that extends previously published research, including the reporting of additional controls and confirmatory results in other settings, as well as negative results. Authors must clearly acknowledge any work upon which they are building, both published and unpublished.

Do not use section headings in the body of the Short communication; combine methods, results, and discussion in a single section. Paragraph lead-ins are permissible. The text should be kept to a minimum and if possible should not exceed 2500 words; the number of figures and tables should also be kept to a minimum. Materials and methods should be described in the text, not in figure legends or table footnotes.

They include essential title page information, an abstract (each Short communication paper must have an abstract of no more than 150 words), keywords, abbreviations (if necessary), a main text, this should contain the body of the article, brief subheadings.

These are reviews that systematically find, select, criticize, and synthesize evidence relevant to well-defined questions about a specific topic.

These manuscripts are systematic, critical assessments of literature and data sources pertaining to a topic and emphasizing on factors. All articles or data sources should be searched for and selected systematically for inclusion and critically evaluated, and the search and selection process should be described in the manuscript. The specific type of study or analysis, population, intervention, exposure, and tests or outcomes should be described for each article or data source. The data sources should be as current as possible, ideally with the search having been conducted within several months of manuscript submission. Authors of reports of meta-analyses of clinical trials should submit the PRISMA flow diagram and checklist. Authors of meta-analyses of observational studies should submit the MOOSE checklist.

They include:

Title. The title should include the phrase “A meta-analysis.”

Text. No more than 4000 words of text (excludes abstract and references).

Introduction, Methods, Results, Conclusions.

References. It is preferable no more than 50-80 references; although, when strictly necessary, more than 100 references can be included, these references may need to be in an electronic only appendix.

Case studies are an invaluable record of the clinical practices of a profession. While case studies cannot provide specific guidance for the management of successive patients, they are a record of clinical interactions that help us to frame questions for more rigorously designed clinical studies. Case studies also provide valuable teaching material, demonstrating both classical and unusual presentations that may confront the practitioner. Quite obviously, since the overwhelming majority of clinical interactions occur in the field, not in teaching or research facilities, field practitioners are the ones to record and pass on their experiences.

The case study should be only 500 to 1500 words in length. Therefore, it will need to be written efficiently and concisely.

They include:

Title. Title should contain the phrase “case study”.

Authors. In a case study, we would not expect to have more than one or two authors. In order to be listed as an author, a person must have an intellectual stake in the writing – at the very least they must be able to explain and even defend the article. Someone who has only provided technical assistance, as valuable as that may be, may be acknowledged at the end of the article, but would not be listed as an author. Contact information – either home or institutional – should be provided for each author along with the authors’ academic qualifications. If there is more than one author, one author must be identified as the corresponding author – the person to be contacted if there are questions or comments about the study.

Introduction. It is useful to begin by placing the study in a historical or social context. If similar cases have been reported previously, describe them briefly.

Case presentation: This is the part of the paper in which the raw data is introduced. First, describe the complaint that brought the patient to seek care. Try to present patient information in a narrative form. In each practice, the history usually leads to a differential diagnosis – a short list of the most likely diseases or disorders underlying the patient’s symptoms. The next step is to describe the results of the clinical examination.

Management and Outcome: In this section, we should clearly describe the plan for care, as well as the care that was actually provided, and the outcome. It is useful for the reader to know how long the patient was under care and how many times he/she was treated. Additionally, be as specific as possible in describing the treatment used.

Discussion: In this section, identify any questions that the case raises and summarize the lessons learned from this case.

References: References should be listed as described elsewhere in the instructions to authors. Only use references that you have read and understood, and actually used to support the case study. Do not use more than approximately 15 references without some clear justification.

Proceedings are devoted to the publication of the presentations at lectures, symposia, meetings. The abstracts and full papers accepted by the International Congress Scientific Committee for publication in the journal will make the required article template available; as well as provide instructions for submission. Please note that your article will be published exactly as received, and no corrections are possible in a later stage. Files should be in MS Word format only and should be formatted for direct printing, using the MS Word template provided. Figures and tables should be embedded and not supplied separately. Do not make any changes to the structure of the template as this can lead to production errors.

Formatting your document. Please do not alter the formatting and style layouts that have been set up in the template document provided by JBBR.
