The Publisher is responsible for advancing its editors credentials by arranging regular online and face-to-face editorial meetings and regularly monitoring and improving the quality of manuscript processing and publishing. Preventing any unethical publishing practice is a top priority for the publisher. If any violations of publication ethics norms are revealed, the publisher and handling editors should take appropriate actions (publishing corrections, initiating retractions, interaction with indexing databases, etc.).

Plagiarism, redundancy and retractions

Discussing others' ideas require proper citation(s). Referring to scientific facts published elsewhere require skilful writing free of verbatim copying and relevant reference(s). The Editors regularly consult with Research Integrity Editor to avoid textual similarity and plagiarism by anti-plagiarism software checks. The authors may be asked to add Disclaimer to their submitted manuscripts to ensure that all parts of their manuscripts, particularly reviews, are original and not posted or published elsewhere.

Duplicate, secondary and redundant submissions

If authors post their article on any preprint server (e.g., medRxiv, bioRxiv) and then submit it to the Journal, they should add related Disclaimer to avoid any confusion post-publication. Ethical duplicate submission of certain materials, such as society recommendations, is acceptable in line with the ICMJE related recommendations (

To avoid redundant publications, the authors of systematic reviews synthesizing evidence based on database searches are requested to register their protocol with PROSPERO registry ( and submit their review with related note.

Conflict of interest disclosures and funding

All authors are requested to fill in and submit the ICMJE conflict of interest form ( at the manuscript submission and disclose any financial and non-financial conflicts of interest in the manuscript notes.

The role of pharmaceutical agencies at all stages of research and writing should be also explicitly disclosed and reported in the manuscript notes.

All reviewers and handling editors will be also requested to disclose their potential conflicts of interest during the peer review.
