Guidelines for Authors 

The McMaster University Medical Journal (MUMJ) is an annual academic journal created to share advances in medicine and to augment our understanding of social issues which impact individual and population health. MUMJ welcomes original articles written by students and faculty of all disciplines and medical residents. The scope of the Journal is wide, encompassing both clinical medicine and non-clinical aspects of health and medicine, such as ethical and legal issues, health policy and history of medicine.

Submissions and inquiries should be emailed to:

Publication Frequency

MUMJ publishes one issue annually in May.

The deadline for submissions is:

​December 31, 2018

Manuscripts are critically reviewed by two members of the MUMJ Editorial Board, as well as by a faculty member with expertise in the topic of the article. The results of this review process are then compiled and assessed by the MUMJ Executive Editors and Editor-in-Chief, who, on the basis of the reviewers’ comments and their own, will determine whether the article will be accepted for publication.

Authors will be informed of the disposition of their manuscripts by email. Articles may be accepted without revisions, conditionally accepted pending specified revisions, or rejected. Authors of articles rejected for publication will receive an email outlining reasons for rejection and suggestions for improvement. Rejected articles may be resubmitted after appropriate changes have been made according to the recommendations of the MUMJ editorial staff. Revised resubmitted articles will be considered new submissions and will be subjected to the standard MUMJ review process. Accepted manuscripts will be edited to conform with MUMJ style and for correctness of grammar, syntax and punctuation.

Manuscripts should conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication (

Articles are to be written in clear and concise English. The manuscript should be typed in 11-point font, double-spaced in an 8.5”x11” format, with 1” margins throughout. Consecutive numbering of all pages is required, with the title page as page 1.

II. Abstract

For Clinical Reviews and Original Research, an abstract capturing the purpose, main findings and principal conclusions of the manuscript must be included. Abbreviations and reference citations should be avoided. Abstracts should not exceed 250 words.

III. References

Authors will be held responsible for the accuracy of the references.

References should be cited in the text by an Arabic numerical superscript. The list of references should appear at the end of the manuscript, according to the order in which they appear in the text.

References with three or fewer authors should list all authors. References with four or more authors should include only the first three authors followed by “et al.” The titles of journals must be abbreviated according to the style used in the list of Journals Indexed for MEDLINE (

Informed Consent

From "Ethical Considerations in the Conduct and Reporting of Research: Privacy and Confidentiality" by the International Committee of Medical Journal Editors.

Patients have a right to privacy that should not be violated without informed consent. Identifying information, including names, initials, or hospital numbers, should not be published in written descriptions, photographs, or pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that an identifiable patient be shown the manuscript to be published. Authors should disclose to these patients whether any potential identifiable material might be available via the Internet as well as in print after publication.

Nonessential identifying details should be omitted. Informed consent should be obtained if there is any doubt that anonymity can be maintained. For example, masking the eye region in photographs of patients is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance, and editors should so note, that such alterations do not distort scientific meaning.

When informed consent has been obtained, it should be indicated in the published article.

Conflict of Interest

From "Ethical Considerations in the Conduct and Reporting of Research: Conflicts of Interest" by the International Committee of Medical Journal Editors:

When authors submit a manuscript, whether an article or a letter, they are responsible for disclosing all financial and personal relationships that might bias their work. To prevent ambiguity, authors must state explicitly whether potential conflicts do or do not exist. Authors should do so in the manuscript on a conflict-of-interest notification page that follows the title page, providing additional detail, if necessary, in a cover letter that accompanies the manuscript.

Authors should identify Individuals who provide writing or other assistance and disclose the funding source for this assistance.

Investigators must disclose potential conflicts to study participants and should state in the manuscript whether they have done so.

Human and Animal Testing

From "Ethical Considerations in the Conduct and Reporting of Research: Protection of Human Subjects and Animals in Research" by the International Committee of Medical Journal Editors:

When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study. When reporting experiments on animals, authors should indicate whether the institutional and national guide for the care and use of laboratory animals was followed.
