Via Medica strongly recommends journal editors to adhere to the principles of Committee on Publication Ethics (COPE), particularly to deal with acts of ethical misconduct. For more information Authors, Readers and Editors may visit the COPE website:


Endokrynologia Polska (EP) (hereinafter referred to as ‘the Journal’) is the official journal of the Polish Society of Endocrinology. The Journal publishes the following types of peer-reviewed articles:

— original research papers,

— rapid communication articles,

— review articles,

— case reports,

— meta-analyses,

— letters to the Editor.

The Journal also publishes editorials, clinical practice guidelines and expert recommendations/position statements, articles specifically focusing on postgraduate education areas, and conference mate­rials. The editors of the Journal endorse the principles laid down in the Declaration of Helsinki and expect all the research involving human subjects to have been conducted in accordance with these principles. In the case of research involving animal experimentation, the editors expect it to have been carried out in accordance with the Interdisciplinary Principles and Guidelines for the Use of Animals in Research, Testing and Education issued by the New York Academy of Sciences Ad Hoc Committee on Animal Research. A statement that the principles laid down in the aforementioned documents have been complied with should be included in the text of the article. It is also required that all the research involving human subjects or animal experimentation has been approved by the relevant local ethics committee, which should also be indicated in the text of the article. The text should also include a statement that all the subjects have given informed consent to participate in the research. Accepted articles are published in the print and online versions of the Journal. The print version is, however, the primary one.

Peer review process

Electronically submitted manuscripts are first checked by the Journal’s editors for completeness and compliance with the house style requirements outlined below. Manuscripts that are incomplete and/or do not comply with the Journal’s house style are rejected without further review. Manuscripts that are complete and comply with the Journal’s house style are reviewed by the Journal’s Edito­rial Board and, if found potentially acceptable, they are assigned a registration number and sent for evaluation by independent reviewers. While the authors are encouraged to suggest the revie­wers for the manuscript, the editors reserve the right to make the final decision. The manuscript is accepted for publication upon favourable opinions of the reviewers, the Editorial Board and the Editor-in-Chief.

Conflict of interest

At the time of manuscript submission, authors of research papers are obliged to disclose any financial arrangements they might have with the company whose product played an important role in the research or with the company manufacturing a competitor product. This information will not be shared with the reviewers and will not affect the decision to publish the paper. After the manuscript is accepted for publication the editors will discuss with the authors the manner in which the information on funding sources should be communicated to the reader. The Journal’s policy requires that the reviewers and editors should disclose, in a letter to the Editor­-in-Chief, any obligations and circumstances that might adversely affect the publishing process of the manuscript being reviewed. Such disclosure should include information on any financial as­sociations with the company manufacturing the drug being the subject of the publication.


Materials previously published should be accompanied by a written consent for reprinting both from the relevant publishers and from the authors of the original paper. If the case report, illustration or original research paper includes information that might identify patients, their written consent for publication must be provided.

Copyright transfer

By submitting the manuscript electronically, along with illustrations and tables, the authors declare that it has not been published before or submitted to the editorial board of any other journal (except for abstracts of up to 400 words). The authors also confirm that they automatically transfer to the Publisher, free of charge, any copyright allowing publication and dissemination of the submitted materials, in all available forms and fields of exploitation (in accordance with Article 50 of the Act on copyright and related rights, including multimedia technologies and dissemination through teleinformatic networks), if the materials are accepted for publication. The authors accepts that the manuscript will not be published elsewhere in any language without the written consent of the copyright holder, i.e. the Publisher.


All individuals who have significantly contributed to the manu­script are considered co-authors. All the co-authors are obliged to indicate their contribution to the publication (conception, design, methods, investigations, analysis of data, writing of the manu­script, etc.). One co-author may indicate more than one type of contribution and the same type of contribution may be indicated by more than one co-author. Other types of contribution, such as provision of reagents or analytical tools, should be disclosed in the “Acknowledgements” section. Ghostwriting and guest-authorship are forbidden as being evidence of lack of scientific diligence. All the detected instances of ghostwriting will be exposed and relevant institutions may be notified.


The Editorial Board and the Publisher make every effort to see that all the information published in the Journal is reliable and accurate. The opinions expressed in the articles and advertisements are, ho­wever, published at the sole responsibility of the authors, sponsors and advertisers. Therefore, neither the Editorial Board nor the Publisher can be held accountable for any consequences resulting from using any inaccurate information. While the doses of drugs and other numeric quantities are carefully checked for accuracy, any treatment regimens described in the Journal should be used in accordance with the relevant product information published by the manufacturers.


Electronic text format

The authors are requested to prepare the manuscripts in a format utilised by the commonly used word processors (e.g. DOC, DOCX, ODT, RTF). The use of standard 10- to 12-point fonts is advised. Tables, figures and photographs should be saved in the following file jpg, or tif. Please do not submit the manuscript as a PDF file. The PDF format is, however, suggested for submitting a cover letter — the authors’ declaration. Abbreviations derived from English terms along with their expansions should be provided in the parentheses after the abbreviated term on its first occurrence in the text. Abbreviations that are not accepted by international groups of experts should be avoided.

The Editorial Board offers fast-track publication of original research papers that due to their breakthrough nature are qualified as rapid communication articles.

Case reports

Main file and supplementary files: as for original research papers. The text should include the following: a concise case presentation; the results of laboratory and other investigations presented, if possible, in the tabular format; the working diagnosis and the differential diagnosis; the definite diagnosis documented by hi­stopathology; and the references.

Review articles

The Journal offers the possibility of publishing review articles upon the submission of the abstract of the proposed article and acceptance by the Editorial Council.

Main file and supplementary files: as for original research papers. The Editorial Board gives preference to manuscripts based on a systematic and qualitative review of the available literature. The proposed review article should include the following sections: Introduction and Conclusions (Summary). The other subheadings should follow logically from the overall outline of the article.

The volume of work

The following recommended word counts should not be exceeded: 3000 words for original research papers, 6000 words for review ar­ticles, 1500 words for case reports, 1000 words for letters (including the references). Abstracts, tables and figures are not to be included in the word count. Supplementary information and acknowledge­ments may be included after the main text and before the references.

Tables, figures and photographs should be black and white and of sufficiently high quality to remain legible after reduction in size by half. They should be numbered consecutively according to the order in which they are mentioned in the text. The descriptions (in English and in Polish) of the tables, figures and photographs should be provided separately. The Editorial Board offers the possibility of printing colour materials on individually agreed terms (including the cost). For any previously published artwork the Publisher’s written permission to reprint must be provided.


The references must be consecutively numbered according to the order in which they are cited in the main text (i.e. they should not be listed alphabetically). Authors must ensure that all references are cited accurately and those in the main text body are also included in the list of references and vice versa. Standard abbreviations should be used for journal names. References older than ten years should only be cited if absolutely necessary. The style of references is that of Index Medicus.

Journals. A citation to a journal should include the following elements: the consecutive number of the reference; a list of the first three authors followed by ‘et al.’ (each author should be listed by his/her surname followed by the initial of his/her first name or by the initials of his/her first and middle names); the article title; the journal title (the abbreviations of the journal titles should be in accordance with the Index Medicus); the year of publication; the volume number (use arabic numbers); the initial and final pages. Do not use such terms as ‘in preparation’ or ‘oral communication’. In justified cases these may be included in the main text. Please note: references you should include DOI numbers of the cited papers (if applicable) — it will enable the references to be linked out directly to proper websites.

Example: 1. Redon J, Cifkova R, Laurent S et al. Mechanisms of hypertension in the cardiometabolic syndrome. J Hypertens 2009; 27: 441–451. doi: 10.1097/HJH.0b013e32831e13e5.
