Reviews may be divided into several sections with headings, according to their content.

Ethical concerns
The journal’s policy follows the principles of the International Committee of Medical Journal Editors (ICNJE), which are available as a pdf file on the website of the journal.

Criteria for authorship: Greek Perinatal Medicine and Neonatology scientific societies insist that all authors are qualified to be listed as such according to the following criteria established by the ICMJE: (1) Conception and design of project or analysis of the manuscript data, (2) Drafting or critically revising the content of the manuscript submitted for publication, (3) Giving final approval of the version to be published. Others who have contributed to the work but are not qualified to be authors should be “acknowledged” at the end of the article.

Informed consent: For experimental articles of human subjects, state in the “Methods” section of the manuscript that the appropriate review board has approved the project. For those investigators who do not have formal Ethics Committee, the principles outlined in the declaration of Helsinki should be followed. Specify in the “Methods” section of the manuscript the way in which consent was obtained from all human subjects. Patient’s anonymity should be respected and not violated. Information, such as the name or photographs of the patients, should not be submitted until written informed consent has been provided. For this case, a Patient Consent Form is available on the journal’s website, which can be submitted with the manuscript.

Final disclosure information and potential conflicts of interest: In the end of the manuscript, all authors must disclose all financial relationships for their research. Any financial interests the authors may have with companies or other entities must be cited such as grants, advisory boards, employment, consultancies, contracts etc. If the authors disclose no conflicts of interest, they should write down “none”. Additionally, the form of disclosure of conflict of interest according to ICMJE available on the website of the journal, should be completed and sent, signed by all authors.
