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.

A. Preparation of Manuscript

Preparation of a paper before submission depends on the type of the manuscript. Nonetheless, every manuscript must include a title page that encompasses 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 full address, email address, and ORCID ID. Here are details on specific topics that may be helpful when preparing a manuscript for submission.

1. Types of Manuscripts:

Original articles: Randomized controlled trials, intervention studies, studies of screening and diagnostic tests, outcome studies, cost-effectiveness analyses, case-control series, and survey-based studies can be sent under this heading. Reports of randomized clinical trials should present information on all major study elements, including the protocol, assignment of interventions, methods of randomization, and masking (blinding). The text should be divided into the following sections: Abstract (structured), keywords, Introduction, Material and Methods, Results, Discussion, Conclusion, References, Tables, and Figures with legends. The recommended word limit is up to 4000 words excluding abstracts, tables, figures, and about 70 references.

Review Articles: Review articles are the systemic critical evaluation of already published material. It is expected that these articles will be written by experts or individuals who have done substantial work on the subject. A review article should be written in the following steps - define the problem, summarize previous investigations to define the state of current research, identify relations, contradictions, gaps, and inconsistencies in the literature reviewed, suggest clinical practice based on the current evidence, and suggest further areas of research. The recommended word limit is up to 4000 words excluding abstracts, tables, figures, and up to 200 references.

Systematic Reviews & Meta-analysis: YJM also encourages the publication of systematic reviews and meta-analyses on various topics of clinical significance. These should provide information on search strategies to retrieve relevant studies, methods used to assess the scientific validity of retrieved studies, and the process of generating a bias-free list of citations to answer the topic under review. The recommended word limit is up to 4000 words excluding abstracts, tables, figures, and up to 150 references.

Short Communications:  A short communication typically follows one of the following formats: a: A concise summary of original research aimed at rapid dissemination. Such articles are particularly suitable for presenting unexpected discoveries or innovative applications that may stimulate further research without the need for extensive background information. b: An article that may not meet conventional research standards but is of general interest to YJM's diverse audience. The text should be divided into the following sections: Abstract (structured), Introduction, Materials and Methods, Results, Discussion, Conclusion, References, Tables and Figures with legends. The recommended word limit is up to 2000 words excluding the abstract, 4 tables and/or figures, and approximately 40 references.

Case reports/case series: New, interesting, or rare cases of clinical significance can be reported. However, mere reporting of a rare case may not be considered. The prescribed word limit is up to 1500 words excluding up to 15 references and abstract. Case reports should be written under the following headings: Abstract (unstructured), Keywords, Introduction, Case Report, Discussion, References, Tables, and Legends in that order. Case series includes cases ranging from 3 to 6 in number, representing the same disease process. It must include an Abstract (non-structured, up to a maximum of 500 words), Introduction, Case reports, Discussion, and Conclusion. (up to a maximum of 2000 words), references up to a maximum of 15, figures up to a maximum of 8, and a maximum of one table

Letter to Editor: Letters to the Editor may report original data or discuss published articles. Letters are not to exceed 1500 words, 2 figures or tables, and 15 references. Letters should not have an abstract. The Editor may solicit a response from the authors. Letters that report original data will be fully peer-reviewed. No abstract or subheadings.

Clinical image: Clinical images are nothing more than highly organized pictorial representations of certain chosen subjects. The primary scope of a Clinical Image article is to present data in a visually compelling manner. The objective is to elucidate a point of medical relevance that may or may not be easily articulated through text alone. The matter should not exceed five figures with its proper description and the description should not exceed 500 words and a maximum of 5 references. Authors submitting for this feature need to incorporate learning points as an isolated paragraph.

Editorials: This type of article is written by members of the editorial board, associate editors, or guest editors on a particular article or topic relevant to the interests of the journal. They contain no more than 2000 words and a maximum of 10 references. No abstract.

Perspectives: Perspectives are opinion pieces that discuss challenging and controversial questions in medicine and health, including issues in developing or rapidly changing areas of medicine. This should not exceed 1500 words, and a maximum of 15 references. No abstract.

Case-based review: These articles offer a more comprehensive synthesis of the literature compared to single case reports. They employ systematic search methodologies, reducing the risk of excluding relevant data, and providing robust evidence. It must include an Abstract (Unstructured), introduction, search strategies, case presentation, and review of the pertinent literature ( This literature review section should synthesize previously published studies and cases related to the subject matter, delineating similarities and distinctions among them to offer a comparative discussion for readers), discussion, conclusion, References, Tables, and Figure with legends. The recommended word limit is up to 3500 words excluding abstracts, tables, figures, and about 100 references.

Book review: A book review is a description and analysis of a book. The purpose of a book review is to heighten your understanding of a book and demonstrate an understanding of the deeper meaning within a book. Recommended word limit is up to 1000 words one figure (cover page), and about 5 references. No abstract.

Spot the diagnosis: It is an educational image of various medical fields. Priority is granted to images that either provide a classic educational message or have a truly unique appearance. Authors submitting for this feature need to incorporate a multiple-choice question with five possible answers in their text and explain what would be considered the right answer. The question should relate to the clinical image in its broadest sense. It could be a diagnostic dilemma, a choice between investigations, a therapeutic decision, or even a related epidemiology or pathophysiology question. The recommended word limit is up to 500 words and five references. No abstract or subheadings.

Commentary: This article reflects the views or insights of the authors. It does not adhere to the conventional structure of introduction, materials/methods, results, conclusion, and references.

B. Manuscript Submission:

All manuscripts must be submitted online through the journal’s online manuscript submission system. Postal submissions will not be entertained.

Steps for the submission of the article

If the corresponding author possesses an existing account with the Yemen Journal of Medicine, he may simply log in and submit their paper. However, if he has not previously published with us and does not have an account, it is necessary to register before submitting their paper. After submitting the manuscript, the corresponding author will be provided a manuscript number that will be used in further correspondence.

Authors are requested to provide the following documents during the submission

(a) Cover letter

(b) Manuscript including tables and figures

C. Manuscript processing

Plagiarism Check

All manuscripts submitted to YJM will be scanned for plagiarism. Plagiarism is checked by the Turnitin. If potential plagiarism is detected, authors will be contacted for clarification. 

Peer Review

All submitted manuscripts (except editorial, and commentary) in YJM undergo double-blind peer review by at least two reviewers. Manuscripts with plagiarized content will not be considered for the peer-review process. All manuscripts are sent to the reviewers anonymously. Comments from reviewers are forwarded anonymously to the corresponding author, who is expected to take appropriate actions and provide responses. All reviewers are required to submit their evaluations within a maximum of two weeks. If the review report presents conflicting decisions, such as one reviewer accepting or requesting revisions while another recommends rejection, a judgment call will be sought. The YJM staff guarantees the completeness of the referee reports. Occasionally, additional time may be necessary to identify suitable reviewers for the process.

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 Assistant 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 author through e-mail. They must carefully check and return the revised manuscript 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.

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.
