INFORMATION FOR AUTHORS

Scope of the Journal the Middle East Journal of Digestive Diseases(MEJDD) aims to publish the highest quality material, both clinical and scientific, on aspects of gastrointestinal and liver diseases. It includes articles related to research findings, technical evaluations, and reviews. In addition, it provides a forum for the exchange of information on all aspects of gastrointestinal and liver, including educational issues. The Middle East Journal of Digestive Diseases is an international, English language, peer-reviewed journal concerned with adult and pediatric gastroenterology and hepatology and colorectal surgery and is published quarterly. Papers submitted to this journal which do not adhere to the instructions for authors will be returned for appropriate revision to be in line with the instructions for authors. They may then be re-submitted. Article categories the Middle East Journal of Digestive Diseases accept the following categories of articles:

Clinical papers:

Clinical studies based on either normal subjects or patients. It is the editorial policy to accept case studies/reports too.

Clinical Trial Registration:

MEJDD requires that randomized controlled trials be registered according to policies accepted by International Committee of Medical Journal Editors and World Association of Medical Editors (WAME). In order to be considered for publication, trials that begin enrolment of patients after January 2008 must register in a public trials registry at or before the onset of enrolment, and trials that began patient enrolment on or before this date must register any time before submission to the journal.

The registration number of the trial and the name of the trial registry must be mentioned at the end of the abstract. Acceptable trial registries include the following: http://www.clinicaltrials.gov ; http://www.anzctr.org.au; http://isrctn.org; http://www.irct.ir; http://www.umin.ac.jp/ctr

First-time users must click "Register" on the navigation menu at the top of the screen. The system will accept automatically your user name and password. Detailed guidelines for authors and reviewers are available at the submission site. Review of manuscripts all manuscripts correctly submitted to the Middle East Journal of Digestive Diseases will first be reviewed by the editors. Some manuscripts will be returned to authors at this stage if the paper is deemed inappropriate for publication in the Middle East Journal of Digestive Diseases, if the paper does not meet submission requirements, or if the paper is not deemed to have a sufficiently high priority. All papers considered suitable by the editors to progress further in the review process will undergo appropriate peer review and all papers provisionally accepted for publication will undergo a detailed statistical review.

Fast track publication authors must send their manuscript by e-mail to: mejdd@iagh.org ensuring that the manuscript adheres to the Middle East Journal of Digestive Diseases instructions for authors. The accompanying cover letter should detail why the authors think the manuscript would be suitable for fast track publication. The editorial office will communicate whether fast track assessment is appropriate within 48 hours. If the editors decide not to accept fast track assessment, the paper may be considered for the normal review process. Authors will also have the opportunity to withdraw their submission. Please note that fast track assessment does not in any way guarantee acceptance of the manuscript. For manuscripts entering fast-track assessment, the first Editorial decision will be made within 7 working days. If provisionally accepted, a revised manuscript must be returned to the editorial office as soon as possible. If the manuscript is accepted for publication, the editors will aim to publish it online 15 days after acceptance and in print within the following 8 weeks. Provided galley proofs are returned within 72 hours. Please note: all authors of accepted articles are required to sign an authorship statement. If your article is accepted for fast track publication, you will be required to submit this form immediately, a delay in submitting the form signed by all authors will result in a delay in publication.

Ethical consideration:

The implemented guidelines are in accord with the uniform requirements for manuscript submitted to biomedical journals (http://www.icmje.org/privacy). The editorial office reserves the right to edit the submitted manuscripts in order to comply with the journal's style. In any case, the authors are responsible for the published material. The research that involves human beings (or animals) must adhere to the principles of the declaration of Helsinki (http://www.wma.net/e/ethicsunit/helsinki.htm).

Ethics of Publication:

The MEJDD’s policy regarding suspected scientific misconduct including plagiarism, fabricated data, falsification, and redundancy is based on the guidelines on good publication practice of the “Committee on Publication Ethics (COPE)”. The complete guidelines appear on COPE website: http:/www.publicationethics.org.uk.

Authorship:

Due to uniform requirements for manuscript submitted to medical journals "an author" is generally considered to be someone who meets the conditions 1,2, and 3." 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data, 2) drafting the article or revising it critically for important intellectual content, and 3) final approval of the version to be published."

Plagiarism:

The authors are not allowed to utilize verbatim text of previously published papers or manuscripts submitted elsewhere. Preparation of manuscripts All submitted manuscripts must not exceed 5000 words (or for editorials 1500 words and correspondence 500 words), including references, figure Legends and Tables. The number of Tables, Figures and References should be appropriate to the manuscript content and should not be excessive. Style and spelling: Oxford english spelling should be used. Authors whose first language is not English are requested to have their manuscripts checked carefully before submission. This will help expedite the review process and avoid confusion.

Abbreviations of standard SI units of measurement only should be used. Sections of the manuscript: Clinical and pre-clinical papers should be divided into the following sections: (1) Title page, (2) Abstract and Keywords, (3) Introduction, (4) Methods and Materials, (5) Results, (6) Discussion, (7) Acknowledgments, (8) References, (9) Figure legends, (10) Appendices, (11) Text tables, (12) Figures. General format: Prepare your manuscript text using a Word processing package (save in. doc or .rtf format). Submissions of text in the form of PDF files are not permitted. Manuscripts should be double-spaced, including text, tables, legends and references. Number each page. Please avoid footnotes; use instead, and as sparingly as possible, parenthesis within brackets. Enter text in the style and order of the journal. Type references in the correct order and style of the journal. Type unjustified, without hyphenation, except for compound words. Type headings in the style of the journal. Use the TAB key once for paragraph indents. Where possible use Times New Roman for the text font and Symbol for the Greek and special characters. Use the word processing formatting features to indicate Bold, Italic, Greek, Maths, Superscript and Subscript characters. Clearly identify unusual symbols and Greek letters. Differentiate between the letter O and zero, and the letters I and the number1. Mark the approximate position of each figure and table. Check the final copy of your paper carefully, as any spelling mistakes and errors may be translated into the typeset version. Title page: The title page should include the following: (1) the title, (2) the name(s) of authors (no more than 12 authors are acceptable), (3) the institution(s) where work was performed, (4) the position, institution, and location of all authors, (5) the telephone number, fax number and e-mail address of the corresponding author (6) the institutional affiliations of the authors (including corporate appointments) should be acknowledged in a footnote.

Abstract:

All abstracts may not contain more the 200 words. The abstract should be formatted with the following heading: (1) BACKGROUND, (2) METHODS (3) RESULTS (4) CONCLUSION, and KEYWORDS. A maximum of six keywords may be submitted.

Figures:

The review process will not begin until all figures are received. Figures should be limited to the number necessary for clarity and must not duplicate data given in tables or in the text. They must be suitable for high quality reproduction and should be submitted in the desired final printed size so that reduction can be avoided. Figures should be no larger than 125 (height) x 180 (width) mm (5 - 7 inches) and should be submitted in a separate file from that of the manuscript. Electronic submission of figures: Figures should be saved in TIFF or jpg format at a resolution of at least 300 pixels per inch at the final printed size for colour figures and photographs, and 1200 pixels per inch for black and white line drawings. Although some other formats can be translated into TIFF format by the publisher, the conversion may alter the tones, resolution and contrast of the image. Digital colour art should be submitted in CMYK rather than RGB format, as the printing process requires colours to be separated into CMYK and this conversion can alter the intensity and brightness of colours. Therefore authors should be satisfied with the colours in CMYK (both on screen and when printed) before submission. Please also keep in mind that colours can appear differently on different screens and printers. Failure to follow these guides could result in complications and delays where there is difficulty submitting the figures electronically, they may be sent, separately from the manuscript, by post to: Middle East Journal of Digestive Diseases, Unit 1, No. 37, 7th St., Kargar-e-Shomali Ave., Tehran, Iran.

Photographs:

Photographs should be of sufficiently high quality with respect to detail, contrast and finesses of grain to withstand the inevitable loss of contrast and detail inherent in the printing process. Please indicate the magnification by a rule on the photograph. Colour figures: There is no charge for the inclusion of colour figures. Colour figures can be uploaded as online Supplementary data at no charge. Line drawings: Please provide these as clear, sharp illustrations, suitable for reproduction as submitted. All labeling should be on the original. Faint and grey shading or stippling will be lost upon reproduction and should be avoided. Where various shadings are used within one figure please ensure that it is easy to differentiate between them, using standard shading (see the hard copy of the journal for examples). There should be sufficient white space between lines and dots to ensure the areas will not fill in and look grey. If stippling is used, this should be made up of clear lack dots with visible white space between them. Ensure that the size of the lettering is in proportion with the overall dimensions of the drawing. Ideally, the drawings should be submitted in the desired final printed size to avoid reduction. If submitting line drawings which require reduction, please check that the lettering will be clearly legible after the drawing has been reduced to the size at which it will be printed. After reduction, letters should not be smaller than 2 mm in height. Figure legends. These should be on a separate, numbered manuscript sheet grouped under the heading "Legends" on a separate sheet of the manuscript after the References. Define all symbols and abbreviations used in the figure. Common abbreviations and others in the preceding text should not be redefined in the legend. Tables: Tables should be typed with double spacing, but minimizing redundant space, and each should be placed on a separate sheet. Tables should be submitted, wherever possible, in a portrait, as opposed to landscape, layout. Each Table should be numbered in sequence using Arabic numerals. Tables should also have a title above and an explanatory footnote below.

Conflict of interest:

All authors must make a formal statement indicating any potential conflict of interest that might constitute an embarrassment to any of the authors if it were not to be declared and were to emerge after publication. Such conflicts might include, but are not limited to, shareholding in or receipt of a grant or consultancy fee from a company whose product features in the submitted manuscript or which manufactures a competing product. The statement should be positioned before the list of references. If there are no conflicts of interest, please insert the wording 'Conflict of Interest: The authors declare no conflict of interest related to this work.

Acknowledgments:

All sources of funding and support, and substantive contributions of individuals, should be noted in the acknowledgments, positioned before the conflict of interest statement.

Format References should be identified in the text by Arabic numerals and numbered in the order cited. All references should be compiled at the end of the article in the Vancouver style: Complete information should be given for each reference including the title of the article, abbreviated journal title and page numbers. Maximum of 6 authors should be listed. Personal communications, manuscripts in preparation and other unpublished data should not be cited in the reference list but may be mentioned in parentheses in the text.
