Author Guidelines


Health Sciences and Disease, the Journal of the Faculty of Medicine and Biomedical Sciences of the University of Yaounde 1, is a peer reviewed medical journal that covers all aspects of medicine, pharmacy, biomedical and health sciences, including public health and societal issues. It is an “online first” publication, which means that all the publications articles appear on the website before being included in the print journal. The papers are published in full on the website, with open access.

Our vision is to be the leader medical journal in our region.

Our mission is to inform and educate all the health professionals and to promote constructive debate on health issues that matter in the management not only of diseases but of health as a whole.

The HSD team is based in Yaounde (Cameroon). L

Acceptance of manuscripts is based on the originality, the quality of the work and validity of the evidence, the clarity of presentation, and the relevance to our readership. Publications are expected to be concise, well organized and clearly written. Authors submit a manuscript with the understanding that the manuscript (or its essential substance) has not been published other than as an abstract in any language or format and is not currently submitted elsewhere for print or electronic publication.


The preferred way for submission is the online submission. Please, refer to the Health Sciences and Disease home page:

Otherwise, manuscripts can be addressed  to Inquiries about manuscript status and preparation, as well as letters to the editor, should be directed to

HSD’s Publications Policy Committee follows the recommendations of the International Committee of Medical Journal Editors (ICMJE), the World Association of Medical Editors (WAME), and the Committee on Publication Ethics (COPE) for guidance on policies and procedures related to publication ethics. The policies for HSD  have been adapted from those three advisory bodies and, where necessary, modified and tailored to meet the specific content, audiences, and aims of HSD.

A.     Plagiarism, scientific Misconduct

Manuscripts proven of plagiarism will be returned to the authors without peer review. The editors reserve the right to request that the authors provide additional data collected during their investigations. The editors also reserve the right to send a copy of the manuscript and data in question to the author’s dean, university, or supervisor or, in the case of an investigation being funded by an agency, to that funding agency for appreciation.

B.     Conflict of Interest

At the time of submission, authors are asked to disclose whether they have any relationship(s) that may influence directly or indirectly the work submitted for consideration.


C.     Human and Animal Studies

Manuscripts reporting results of prospective or retrospective studies involving human subjects must document that appropriate institutional review board (IRB) approval and informed consent were obtained (or waived by the IRB) after the nature of the procedure(s) had been fully explained.


D.     Authorship

To be listed as an author, an individual must have made substantial contributions to all three categories established by the ICMJE ( (a) “conception and design, or acquisition of data, or analysis and interpretation of data,” (b) “drafting the article or revising it critically for important intellectual content,” and (c) “final approval of the version to be published.” Individuals who have not made substantial contributions in all three categories but who have made substantial contributions either to some of them or in other areas should be listed in acknowledgments.


E.     Language

HSD is bilingual and accepts publications in French and English. All the publications should have title and abstract in both languages. Whenever possible picture captions and table titles should be in both languages.


A.     Original articles

You may acknowledge those who have contributed substantially to the work reported in the manuscript but who have not fulfilled the ICMJE requirements for authorship. Those acknowledged must submit written permission to be cited.

Authorship Contributions and Disclosure of Conflicts of Interest

Any involvement of medical writers/researchers, particularly those employed or supported by the pharmaceutical industry, in the writing of an article must be clearly defined and disclosed in the Authorship and/or the Acknowledgements section(s) as appropriate. This type of involvement must also be disclosed to the Editor-in-Chief in the Cover Letter.


Number references consecutively in the order in which they are first mentioned in the manuscript. The abbreviations used for periodicals cited in the references should follow the style of the National Library of Medicine. Abstracts, editorials, and letters to the editor should be noted as such. Articles that appear in online journals should follow the same citation format as print articles, with the addition of the URL and the date the article was accessed. In the case of books, the authors of a chapter, title of the chapter, editor(s), title of the book, edition, city and state, publisher, year, and specific pages must be provided.

For Web content, the following items should be listed: author(s) (if any); title of the page or content; name or owner of the Web site; URL; and publication, update, and access dates. It is the responsibility of the author(s) to verify the accuracy of all references to ensure linking of referenced articles in the online journal.

The authors are strongly encouraged to use zotero free software as their references manager.


Tables should be and should have a title. All abbreviations used in the table should be explained in a footnote. Tables should be presented in the style used in recent issues of the journal. Tables should be prepared in Word or Excel and embedded in the text document, each on a separate page. The number of tables should not exceed four.

Figure legends

Figures should appear sequentially in the text. A caption must be supplied for each illustration, including drawings and graphs, and should not duplicate text material. It is essential that the caption describe all labels placed on an illustration. The caption should include the type of image and the features to be observed by the reader. For photomicrographs, include the stain and original magnification.

Images and illustrations

Digital images must be 300 dpi (dots per inch; 1200 dpi for line art) and no larger than 15 × 15 cm or smaller than 5 × 5 cm.


When essential for the understanding of the study, detailed background information, mathematical derivations, statistical analyses, and the like should be presented in one or more appendices. Include in the appropriate section of the text (e.g., Materials and Methods, Results) a brief summary of the information contained in the Appendix, and make reference to the Appendix.

Supplemental Material

Online-only publication of supplemental material is designed to take full advantage of the Internet medium and allows publication of material that cannot be accommodated in print. This material can include (a) multimedia (e.g., animation, dynamic image sets [movies], audio), (b) large numbers of relevant images whose number would exceed the limits of print publication, (c) relevant data in the form of tables or text that could not be accommodated in the print version, and (d) interactive materials such as Java applets and other programs for expanding browser capabilities and interactivity in areas such as image display and computer-assisted instruction.

Check lists

  1. For studies dealing with diagnostic accuracy, use the Standards for Reporting of Diagnostic Accuracy (STARD)
  2. For randomized controlled trials, use the CONSORT (Consolidated Standards of Reporting Trials) statement (BMJ 2010; 340).
  3. For systemic reviews and meta-analyses of diagnostic test accuracy studies, follow the PRISMA-DTA (Preferred Reporting Items for Systematic Reviews-Diagnostic Test Accuracy) guidelines)
  4. For observational studies, such as cohort, case-control, or cross-sectional studies, use the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Use of checklists allows authors to describe their work more effectively, aiding the detailed scientific review of their work and its implications for patient care or future biomedical research. This critical evaluation also aids authors in the discussion of the limitations and biases inherent in their study.




B.     Clinical Cases

This section presents clinical cases with practical lessons for the developing countries. Preference is given to common presentations of important rare conditions, and important unusual presentations of common problems. Clinical cases should be formatted in the following manner:

  • The word limit for the main text is 2,000 words. (The total word count excludes the title page, abstract, acknowledgments, references, tables and figures, and table/figure legends.)
  • The report should contain no more than 25 references and the reference section should be single spaced with justified margins.
  • The article should contain no more than a combination of four tables and/or figures.
  • Supporting documents/data can be uploaded for review purposes and will not be published. (When uploading, be sure each file is clearly labeled "supporting document/data.")

When patients are potentially identifiable, written consent for publication of the report and for the use of patient photographs, radiographs, etc., must be obtained from patients or their surrogates.


C.     Brief reports

This section can be used for any original paper pertinent to the journal. The aim is to publish important data or opinions that can be concisely presented. The section can take any of the following:

  • Articles written by experts and providing up to date information or personal point of view regarding diagnosis and treatment of important clinical situations. Here, clear distinctions should be made between evidence-based versus experience-based recommendations.
  • Articles that present key statements on topics of interest to caregivers. The article should address important, missed, controversial or new information and can take the form of a sentence supported by a few sentences with references. Tables and images are permitted.
  • Clinical images that are original, relevant to the African context and particularly informative. The high resolution images should be labeled and accompanied with a caption, and when necessary the patient's written consent for publication. The author should also provide a short commentary emphasizing the lessons to be learned and some references.
