2. Editorial Review And Acceptance

Acceptance: The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. All manuscripts are peer reviewed. The Editor reserves the right to refuse any material for publication. Final acceptance or rejection rests with the Editorial Board.
Review process: A submitted paper is assigned to one of the associate editors according to the topics of paper. The responsible associate editor appoints more than two reviewers for evaluating the paper and decides whether the paper should be accepted for publication, revised or rejected, according to the reviewers’ comments within four to six weeks.
Before publication: All manuscripts should be written in a clear, concise, direct style so that they are intelligible to the professional reader who is not a specialist in the particular field. Where contributions are judged as acceptable for publication on the basis of content, the Editor reserves the right to modify manuscripts to eliminate ambiguity and repetition and improve communication between author and reader. If extensive alterations are required, the manuscript will be returned to the author for revision.

The Editorial Policies and General Guidelines for manuscript preparation specified below are based on “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations)” by the International Committee of Medical Journal Editors (ICMJE) (

Preparation of original articles, systematic reviews, meta-analyses, and case reports must comply with study design guidelines:

The purpose of the PDF proof is a final check of the layout, and of tables and figures. Alterations other than essential corrections of errors are unacceptable at PDF proof stage.

8. Ethical Considerations

Authors must state that the research project has been approved by an ethics committee of the institution where the work was undertaken. Written consent is not a requirement, but the Editor retains the right to request such documentation. Any experiments involving animals must be approved by an institutional ethical committee which must be declared in the text.

9. Clinical Trials Registry

All clinical trials must be registered. Authors must include registration details in the manuscript. We define a clinical trial as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome.

10. Copyright

All authors must agree to the conditions outlined in the Exclusive License Form, and must sign the form or agree that the corresponding author may sign on their behalf. In signing the form it is assumed that authors have obtained permission to use any copyrighted or previously published material. Authors can download the form here.

11. Offprints

PDF offprint of the online published article will be provided free of charge to the corresponding author, and may be distributed in accordance with the Publisher’s terms and conditions. Paper offprints may be purchased if ordered at the author proof stage.

12. Tracking Manuscript

(1) Before acceptance authors can track a manuscript’s progress through the review process at:
(2) After acceptance authors can get information about the production process of their paper by registering at Galenos Yayinevi. This enables authors to track their article, once it has been accepted, through the production process to publication online and in print. Authors can receive automated emails at key stages of production so they do not need to contact the Production Editor to check on progress. For more details on online production tracking and for a wealth of resources, including FAQs and tips on article preparation, submission and more, visit:

13. Early View

An Early View article is a complete full-text article published on line in advance of publication in a printed issue. The article is therefore available as soon as it is ready. The Early View article is given a Digital Object Identifier (DOI), which allows the article to be cited and tracked before it is allocated to an issue. After print publication, the DOI remains valid and can continue to be used to cite and access the article. More information about DOIs can be found at:
