Guidelines for Authors

Guidance for Authors on the Preparation and Submission of Manuscripts to the Journal of Gastrointestinal and Liver Diseases*

The Journal of Gastrointestinal and Liver Diseases is published quarterly. The manuscripts submitted for publication should report original clinical and scientific human research, which contributes to the advancement of knowledge in the field of gastroenterology and hepatology. The field comprises prevention, diagnosis and management of gastrointestinal and hepatobiliary disorders, as well as related molecular genetics, pathophysiology, and epidemiology. We do not publish animal experimental studies. Due to limited space, we do not accept papers related to pediatric pathology or to surgical techniques.
Submission and procession of manuscripts is free of charge for authors.
Only manuscripts in English language will be accepted.
Submitting a scientific paper for publication is subject to the fulfillment of the following statements:
– the paper is original and has not been published in other journals or books; please consult the recommendations of the International Committee of Medical Journal Editors (ICMJE) regarding overlapping publications;
– the paper does not infringe upon any copyright or other proprietary right;
– the manuscript has been reviewed and approved by all named authors.
All these statements should be included in a formal declaration signed by all the authors. If your paper contains studies on humans, you must insert in the ”Methods” section a statement mentioning the approval of the medical ethical commission of the organization in which the study was realized.

Informed consent
Please send copies of patients᾽ consent forms in which patients or relatives in case the patient cannot, or other subjects of your experiments clearly grant permission for inclusion in the study and/or the publication of photographs or other material that might identify them.
Please note that Journal of Gastrointestinal and Liver Diseases is a member of COPE (Committee on Publication Ethics) and failure to comply with their guidelines may lead to the rejection of the manuscript.

Preparing the manuscripts
The manuscript should be written in a concise style, and should contain the strictly necessary number of pages, figures and tables. For submitting a manuscript in electronic format the following conditions must be fulfilled: – the text should be sent as a Word document, in 12p Times New Roman fonts, 1.5 line spacing. Use only standard abbreviations; the full term for which an abbreviation stands should precede its first use in the text.
In the title and the abstract the abbreviations should be avoided;
– the tables should be numbered with Roman numerals according to the order in which they are mentioned in the text;
– the illustrations / figures should be submitted as separate files named with the corresponding number (e.g. „Figure 1”).
The following formats for figure files are accepted:
• EPS for diagrams / vector images
• JPEG or TIFF for photographs and screen dumps at a resolution of 300 dpi.
Figures that are submitted in colour will be published with reproduction costs (20€ or 24 USD per figure).
– the legend for figures, with Arabic numerals in order of appearance in the text, should be placed on a separate page at the end of the manuscript, after the References.
– the supplementary material should be provided in a single pdf file.
In case of the reproduction of previously published parts or figures, it is necessary to attach the written consent of the author as well as of the publishing house where it was originally published, including the source.
The names of the patients should be concealed on all illustrations; patients in all photos should have a black band over their eyes in order to prevent their identification.

Structure of the manuscript
Title page (on a distinct page) includes only the title of the paper. Any identifiable information should be removed, such as: authors᾽ names, department or institution, or e-mail addresses. This information is entered separately during the submission process on the website. The authors‘ information should be separated from the article to ensure a blind peer review process.
The author responsible for correspondence concerning the manuscript should give his address. Authors should state each contribution to the manuscript. The word count for the text only (excluding abstract, acknowledgement, figure legends, and references) should be noted.
Abstract (on a distinct page) precedes the text body. The abstract should be structured into the same sections as the paper.
Key words. Three to five key words will be written for every paper. Please use Medical Subject Headings (the National Library of Medicine‘s controlled vocabulary thesaurus used for indexing articles for PubMed).
Article content and structure – please see above by article type.
References. Please include the works cited in the paper, according to their occurrence in the text, inserted between square brackets [ ]. Titles of medical journals should be abbreviated according to the Index Medicus. List all authors up to six, using six and „et al.” when the number is greater than six.
Authors are responsible for the accuracy and completeness of their references and for correct text citation! Please add doi whenever possible.

Specific recommendations
If the paper presents the results of observational studies, read the STROBE statement, if the paper reports a clinical trial read the CONSORT statement (publication of clinical trials will be considered only for those registered in a public trials registry). If the paper is reporting the results of a diagnostic study, read the STARD statement, if the paper is reporting the results of a clinical case, read the CARE statement.

Online manuscript submission
Go to www.jgld.ro, click on Guidelines for authors and read the guidelines. Then, back on the home page of www.jgld.ro, go to Submit an article and click. You will register for an account. You will use your account log-in and password each time you return to the site. In case you forget the password, use the button Forgot your password. After you log on, click on Add new article and start to submit the manuscript in the required order for the chapters. You should propose three or more reviewers. Reviewers should be personalities with published papers in the field, from different cities and diverse countries, in order to avoid any possible conflict of interest. Please insert a Word copy of the full manuscript and also a PDF copy including tables and figures in the “Article tables and Full manuscript” section. You click on Send to Editor and your manuscript will be submitted.
Once in our system, the manuscript is assigned a tracking number and you will receive a confirmation letter. As soon as the reviewers’ comments are ready, you will receive a letter from the editor confirming acceptance, inviting you to revise your manuscript, or informing you that the manuscript cannot be accepted for publication.

Peer-review procedure
The Editor-in-chief or one of the editors first reads the manuscripts received and decides upon their priority level: some are immediately sent to the reviewers, some are rejected without being sent for review and some are returned to authors with suggestions for improvement before submitting them to reviewers. Manuscripts will be checked for plagiarism using the sistemantiplagiat.ro.
All original papers are anonymously reviewed by two or three independent reviewers. The reviewers send their comments to the Editor. The Editor will inform the authors about the suggestions made by the referee and ask them to answer the questions and make the required corrections.
The revised manuscript should be returned in no more than two months to the Editor. When the Editor receives the corrected version with all changes marked, accompanied by the reply letter to the reviewers, he sends those back to the same reviewers, who make the final recommendation for acceptance or rejection of the manuscript. The Editor’s decision is final and will not be subject of further correspondence for manuscripts considered unsuitable for publication.

Open access
All original articles, reviews, editorials and case reports published in the journal are available online for all to read and use free of charge.
