Author Instruction

All submitted manuscripts should contain original work neither published previously nor under consideration for publication elsewhere. Articles from any part of the world are accepted provided submitted in English language only. It is recommended that an English check of the manuscript by a competent and knowledgeable native speaker be completed before submission. Moreover, authors should check for Plagiarism in their Article title and work prior to proceeding with submission. Failure to follow these two steps may result in papers being delayed or rejected. All parts of the manuscript should be typewritten in “Times New Roman font” using a font size of 12, double-spaced, with margins of at least one inch on all sides. Pages should be consecutively numbered at the bottom, beginning with the title page.

For detailed instructions on how to submit your article, please visit our submission page: https://yemenjmed.com/submit_manuscript

If the corresponding author already has an account with the Yemen Journal of Medicine, they can log in directly and proceed with the submission. Authors who have not yet published with us and do not have an account will need to register first before submitting their manuscript. Kindly visit our registration page: https://yemenjmed.com/register

Once the submission is complete, the corresponding author will receive a manuscript number for use in all future communication regarding the paper.

Authors are requested to submit the following documents:

(a) A cover letter stating explicitly that the submitted work has not been published previously and is not currently under consideration by any other journal.

(b) A title page file including the following elements: the type of manuscript (such as an original article, review article, short communication, case report, or letter to the editor), the title of the manuscript, a short running title (limited to 50 characters), the names of all authors/contributors (along with their highest academic degrees, designations, and affiliations), the name(s) of the department(s) and/or institution(s) to which the work is attributed, and the details of the corresponding author, which should include their email address, and ORCID ID.

(c) The main Document (Manuscript) file, which must be anonymized—free of author names—and should include the complete text, references, tables, and figures.

C. Manuscript processing (Review cycle)

Steps	Action
Plagiarism Check	All manuscripts submitted to YJM will be scanned for plagiarism. Plagiarism is checked by the Plagiarism Checker X. Any submission identified with over 20% plagiarized content will be returned to the authors for revision to lower the plagiarism percentage or may be outright rejected.
Editorial review	The manuscript first undergoes an initial assessment by the editor to determine whether it aligns with the journal’s scope and meets basic quality standards. If it does, it will be sent out for peer review. Manuscripts deemed unsuitable are rejected at this stage.
Peer review	Following editorial review, all manuscripts submitted to YJM—with the exception of editorials, letters to the editor, perspectives, and commentaries—undergo a double-blind peer-review process by at least two reviewers. Manuscripts are provided to reviewers anonymously, and feedback is sent anonymously to the corresponding author. Reviewers are expected to complete their assessments within four weeks, although delays may occur if appropriate reviewers are not immediately available. Authors are expected to respond appropriately to the comments received. In cases of conflicting recommendations from reviewers—for example, if one reviewer recommends acceptance or revision while another recommends rejection— a third reviewer will be invited to help making a decision.
Revision and Resubmission	If revisions are requested, authors are given a reasonable timeframe to address the reviewers' comments and revise the manuscript accordingly. Upon resubmission, the revised manuscript undergoes further evaluation by the Editor-in-Chief or Associate Editor to ensure that the revisions adequately address the reviewers' concerns.
Final Decision	The Editor-in-Chief or Associte Editor makes the final decision based on the revised manuscript and the authors' response to the reviewers' comments. Once accepted, manuscripts are prepared for publication, and authors are notified of the publication process.
Article Proofs	Manuscripts accepted for publication are copy-edited for grammar, punctuation, print style, and format. Page proofs are sent to the corresponding authors through e-mail. They must carefully check and return the revised manuscripts within 72 hours. It is the responsibility of the corresponding author to ensure that the galley proof is to be returned without delay with correction. In case of any delay, authors are responsible for the contents that appear in their published manuscripts.
Online first publication	Online First articles are made available on the website prior to their inclusion in a journal issue and can be referenced and cited using their DOI. The YJM maintains a policy stating that no alterations will be permitted following the publication of an article, except in cases where an error has been attributed to the journal.

Editors and editorial members as Authors

The editor of the journal is a distinguished researcher within his or her area of expertise. Consequently, there exists a significant conflict of interest regarding the decision to submit an original research report as an author to his or her own journal. The editor seeks to implement a strategy for managing this conflict of interest and would appreciate the insights and guidance of COPE.

The central question pertains to the acceptability of editors publishing their own research in their journals; if deemed acceptable, it is imperative that the review process is both transparent and rigorous. Final decisions regarding the publication of such articles will be made by other members of the editorial board who do not have any conflicts of interest with the authors.

Artificial Intelligence as Author

Artificial Intelligence (AI) is not eligible to be recognized as an author and should not be attributed as one. If AI contributed to the research or development of the paper, this involvement must be disclosed and clarified in the section detailing the tools or methodologies employed. All regulations regarding copyright and plagiarism remain in effect.
