IJEHS is aimed to promote scientific communication among all investigators working on epidemiologic research worldwide. IJEHS, which benefits from an international editorial board, is published continuously. Contents include free-of-charge peer-reviewed research papers covering different aspects of epidemiology and health sciences research.
IJEHS publishes original clinical research articles, brief communications, review articles, case reports, editorials, and letters to the editor. Contributions in any of these formats are invited for editorial consideration following free-of-charge peer review by at least three experts in the field. Submissions should conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.
Informed Consent: In the case of clinical trials informed consent should be obtained from the participants, or in the case of minors from the parents. This should be explicitly indicated in the published article at the very beginning of the method section. A sample of informed consent form should be sent to the IJEHS after acceptance.
Human and Animal Rights: 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 or national) and with the last update of Helsinki Declaration (Uniform Requirements for Manuscripts Submitted to Biomedical Journals). 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.
Authors are responsible for disclosing all financial and personal relationships that might bias their work. It is recommended that the authors state explicitly whether potential conflicts do or do not exist, preferably in the manuscript on a conflict of interest notification page that follows the title page and if necessary, in a cover letter that accompanies the manuscript.
Unsolicited manuscripts will be reviewed for publication with the following understanding that:
- They represent original work
- The paper neither was published already nor is being under review elsewhere
- Submitted papers may be examined for the evidence of plagiarism using some automated plagiarism detection services
- In cases of suspected plagiarism, necessary actions as recommended by the COPE Guidelines will be followed
Abstract or press reports of presentations at scientific meetings will not be considered prior publication. The editorial will not enter an argument with authors about papers considered unsuitable for publication and their decision is final.

The type and extent of contribution of each author should be explicitly stated in the Authors' Contribution section of the manuscript. The form of "Authorship Contribution Form" must be filled and send to the journal after acceptance.
Conflict of interest
The authors must identify any potential financial conflicts of interest before the review process begins. Declared conflict of interest will not automatically result in rejection of paper but the editors reserve the right to publish any declared conflict of interest alongside accepted articles. The following would generally be regarded as potential conflicts of interest:
- Direct financial payment to an author for the research or manuscript production by the sponsor of a product or service evaluated in an article.
- Ownership of shares by an author in the company sponsoring a product service evaluated in an article (or in a company sponsoring a competing product).
- Personal consultant with companies or other organizations with a financial interest in the promotion of particular health care products and services.
General original works are in priority, but content from different medical disciplines may be considered for publication, provided that the topic is not limited to a certain sub-specialty. Such papers may be better to be submitted to specialty or sub-specialty journals. Certain sub-specialty articles discussing inter-disciplinary topics may be considered for publication.
Original articles should clearly describe the reason for undertaking the work, and present methods used and the results found in separate sections. Scientific interpretations based on the findings should be presented in a discussion section; a self-critical / examination of the findings is encouraged.
Brief Communications are treated like original articles, except that they should be limited to 1400 words, with an abstract of 150 words or fewer.
A review article is an analysis and collection of the current state of the research on a topic. It is not an original article with new data but represents:
- the main people working in a field
- recent major advances and discoveries
- significant gaps in the research
- current debates
- ideas of where research might go next
Review articles are usually invited by the Editor, although we will consider unsolicited material. All review articles, even if invited, undergo the same peer-review and editorial process as original research reports. These articles need an abstract. The text is limited to 4000 words, with a maximum of 6 tables and figures (total) and up to 150 references.
A case-report can present the signs, symptoms, diagnosis, treatment, and follow-up of an individual patient. It usually describes an unusual or novel occurrence and provides new ideas in medicine. Case-report may contain an extensive review of the relevant literature on the defined topic. In fact, a case-report is a rapid brief communication for the clinicians without enough time.
A case-report may deal with one or more of these issues: Unusual observations, Adverse response to therapies, Unusual combination of conditions leading to confusion, Illustration of a new theory, Question regarding a current theory, Personal impact.
A case-report must include the following parts: an abstract, an introduction, a case, and a discussion.
The abstract must summarize the case, the addressed problem, and the message.
The introduction may give an overall overview of the problem that the case may address, citing relevant literature if it is necessary. The introduction generally ends with a single sentence describing the patient and the basic condition that he or she is suffering from.
Case section provides the details of the case in the following order: Patient description, Case history, Physical examination results, Results of pathological tests and other investigations, Treatment plan, Expected outcome of the treatment plan, and Actual outcome.
All the relevant details should be included, and unnecessary ones excluded.
Discussion section is the most important part of a case-report. This part will convince the journal that the case is suitable for publication. It must start by expanding on what has been said in the introduction, focusing on why the case is important and the addressed problem.
This is followed by a summary of the existing literature on the topic by describing the current theories and research findings on the key issue in the patient's condition.
Finally, the case-report should be connected to the current literature, by mentioning the message of the case-report, current beliefs about the problem, and how this reported evidence can add value to future clinical practice.
Conclusion section could end the case-report by a conclusion or with summary points. The conclusion should briefly give readers the key points covered in the case-report by giving suggestions and recommendations to clinicians, teachers, or researchers.
Informed consent is an ethical requirement for studies on humans; thus, before starting to write the case-report, take a written consent from the patient that will provide after acceptance. In case the patient is a minor, parental consent is required. For adults who are unable to consent to investigation or treatment, the consent of closest family members is required.
Remember not to mention any information that might reveal the identity of the patient. It is necessary to be careful with pictures and ensure that pictures of the affected area do not reveal the identity of the case.
Unsolicited editorials will be reviewed for publication as short commentaries on topics of current interest to medical public health practitioners. Editorials should be 1,200 words or fewer.
Letters to Editor
Letters to the editor on any topic of interest to the medical and public health community will be considered for publication. Letters should be double spaced and limited to 500 words.
The type and extent of contribution of each author should be explicitly stated in the Authors' Contribution section of the manuscript. "Authorship Contribution Form" should also be filled in.
