Aim and Scope

Siriraj Medical Journal (SMJ) aims to promote communication among researchers in health sciences. It is published bimonthly and accepts the manuscripts in the forms of the original article, case report, review article, and others in various aspects of biomedical sciences. It is academically double-blinded peer-reviewed and designed for all physicians, researchers, and health personnel, regardless of their specialties, or types of employment.

All manuscripts submitted to SMJ must be previously unpublished and may not be considered for publication elsewhere at any time during SMJ’s review period.

Instructions for Authors

Siriraj Medical Journal (SMJ) is a peer-reviewed biomedical journal. It is published bimonthly and accepts the manuscripts in the forms of original article, case report, review article, and others in various aspects of biomedical sciences. Starting from November 1, 2013 the editorial office will seek at least two experts who work in the institutions different from the author institution(s) to consider the manuscript content as reviewers for the peer review process. Peer review is intended to examine the quality of manuscripts in term of accuracy, clarity, research methodology, ethics, and usefulness to the readers and the general public. The peer reviewers should not have any conflicts of interest related to the manuscript assigned for the revision. The Editor-in-Chief will make the decision regarding acceptance of any manuscript for publication by taking the opinions of at least one member of the editorial board and from the peer reviewers for the consideration. More opinions from other experts may be sought for the decision to accept some particular manuscripts for publication.

General information for submission of manuscripts

Starting from March 1, 2009, all manuscripts submitted to SMJ should follow the details given below. Authors are encouraged to submit manuscripts via www.sirirajmedj.com. For the text and tables, the manuscripts should be saved in a Microsoft word file. Page setup should be made on the size of A4 paper (210 x 297 mm) and the type setting should be double-spaced. The font should be “Times New Roman” with the size of 12 pt. The top, bottom and side margins should be 25 mm. wide. All pages should be numbered consecutively together with the first author’s name at the top right-hand corner, beginning with the title page. For illustrations, the digital file should be in JPEG format, no larger than 800 kB per file. All digital files should be free of any virus or other malicious threats (e.g. spyware, adware, trojan, worm). No printout of the manuscripts is required for submission in order to conform to our “less-paper usage” policy to save the world and reduce the global warming crisis. Any manuscript submission that fails to follow this instruction will be returned to the authors without review.

SMJ accepts the World Medical Association Declaration of Helsinki Ethical Principles for Medical Research Involving Human Subjects (Seoul, 2008), which states:

“30. Authors, editors, and publishers all have ethical obligations with regard to the publication of the results of research. Authors have a duty to make publicly available the results of their research on human subjects and are accountable for the completeness and accuracy of their reports. They should adhere to accepted guidelines for ethical reporting. Negative and inconclusive as well as positive results should be published or otherwise made publicly available. Sources of funding, institutional affiliations and conflicts of interest should be declared in the publication. Reports of research not in accordance with the principles of this Declaration should not be accepted for publication.” [http://www.wma.net/e/policy/b3.htm].

Thus, for any new research project involving human research subjects, including the case report of more than 1 patient, starting from 1 March 2009, the authors need to submit a photocopy of a document of approval from Institutional Review Board (IRB) or Institutional Ethic Committee (IEC). For any research project involving human research subjects starting before 1 March 2009 that does not have a document of approval from IRB or IEC, the authors need to convince the editorial board that the research does not violate any ethical concern on human research subjects.

SMJ also accepts the World Medical Association Declaration of Helsinki Ethical Principles for Medical Research Involving Human Subjects (Seoul, 2008), which states:

“19. Every clinical trial must be registered in a publicly accessible database before recruitment of the first subject.” [http://www.wma.net/e/policy/b3.htm].

Thus, for any new clinical trial starting from 1 March 2009, the authors need to register at the public clinical trial registry prior to the research conduct. Registration number should be placed at the end of the abstract in parentheses. For any clinical trial starting before 1 March 2009 that does not have the registration number, the authors need to convince the editorial board that the clinical trial does not violate any good clinical practice guidelines or any ethical concern on human research subjects.

All manuscripts submitted to SMJ should follow the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication” that has been updated on December 2013 by the International Committee of Medical Journal Editors (ICMJE). Authors who want to submit the manuscript to Siriraj Medical Journal are encouraged to learn more about the latest version of the “Uniform Requirements” from the website of ICMJE at http://www. icmje.org/. The “Uniform Requirements” also provide criteria for authorship.

All authors should approve the submission of the manuscript and the cover letter should indicate that the manuscript is submitted to SMJ only and it has never been published elsewhere in English or other languages. Authors should be aware of copyright violation, conflicts of interest, plagiarism, and other misconducts in biomedical research and publication. Written permissions from persons who provide personal communication or from those to be acknowledgedin the manuscript are required in case the readers may infertheir endorsement of such activities as technical assistance,provision of illustration, etc.

Since 1949, SMJ has maintained the same policy as thatthe present “open-access” journals adopt that the authors arenot required to transfer their copyright to the editorial office.Thus, after publication in SMJ, the copyright of the printedmaterial in forms of both hard-copy and online versions stillbelongs to the author(s). The readers who are interested inreproduction or dissemination of a particular article publishedin SMJ should make a direct contact to the correspondingauthor of the paper.
