Instructions for Authors

The Editorial Board accepts for publication only manuscripts written in US English. Authors not entirely familiar with English usage are advised to seek assistance of an English speaker; correct style is the responsibility of the authors. The journal does not offer translation services.

Please note that your paper – if accepted for publication – will initially be published online as an ahead of print article (with active DOI, registered in PubMed, but without page numbers) as soon as possible. Later the same paper will appear in an issue (DOI does not change) with numbered pages (the contents of our issues are planned in advance).

 

Types of manuscripts

Manuscripts may be considered for publication in the following sections:

  • Original papers – including experimental research;

  • Reviews;

  • Meta-Analyses.

The submitted manuscripts should meet the general standards and requirements agreed upon by the International Committee of Medical Journal Editors, known as “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals”. They should also conform to the high-quality editorial procedures and practice (formulated by the Index Copernicus International Scientific Committee as Consensus Statement on Good Editorial Practice 2004).

All research presented in papers accepted for publication in our journal should be conducted in strict adherence to rules, guidelines, international conventions/declarations and other regulations pertaining research on humans, animals and cell lines.

If your submission relates to a clinical trial, include the number and registration date.

 

Submission of manuscripts

All manuscripts should be submitted to Editorial Office via electronic Editorial SystemWe do not accept manuscripts sent by post or e-mail. We perform no pre-assessment of papers sent by e-mail regarding their scope or publication possibility.

The manuscript should be anonymized – please remove all names and affiliations of the authors from the main text. Please make sure that all names of the authors and their affiliations are registered in the Editorial System during the submission.

There should be no title page – either as the first page of the paper or as a separate file. All authors should be registered in the Editorial System during the submission of the paper and the Editorial System will generate a title page. An “Authors' contributions” section should not appear at the end of the paper.

The Author(s) should provide a short title that does not exceed 45 characters and spaces.

The Author(s) should disclose all financial and material support when registering the paper in the Editorial System. Should any conflict of interest arise, it should be reported while submitting the manuscript in a dedicated section of the submission procedure in our Editorial System. Information about funding sources should be reported while submitting the manuscript in a dedicated section of the submission procedure, not in the Acknowledgements section of this procedure. Both acknowledgements and the information on funding sources and conflict of interest should be registered in the Editorial System during the submission process and removed from the main body of the paper.

 

Preprints

If the article is already accessible online as registered preprint on any website or in any database, and has been already assigned with a DOI, such information, together with an URL of the registered preprint, has to be provided during submission of the paper as well as appear in the cover letter. We encourage posting of preprints of manuscripts on preprint servers such as BioRxiv, MedRxiv or ResearchSquare, as well as on authors’ or institutional websites. During submission of a manuscript to our journal, the authors must disclose that the paper has already been released as a preprint and provide a link to the preprint.

Preprints are defined as an author’s version of a research manuscript prior to formal peer review at a journal, which is deposited on a public server. Preprints may be posted at any time before or during the peer review process, but not after acceptance in the journal. Posting of preprints is not considered as a prior publication and the manuscript can enter peer review at Polimery w Medycynie – Polymers in Medicine following the regular procedure.

Once the preprint is published in our journal, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.

 

Financial disclosure

All affiliations or financial involvement (e.g., employment, consultancies, honoraria, stock ownership or options, expert testimony, grants, patents received or pending, royalties) with any organization or entity with a financial interest in, or in financial competition with, the subject matter or materials discussed in the manuscript must be completely disclosed in the submitted manuscript. All financial and material support for the research and work must be clearly identified, including listing of support that might constitute or give the appearance of influencing the findings. Report all support for the work reported in your manuscript without time limit.

Information about funding sources should be reported while submitting the manuscript in a dedicated section of the submission procedure, not in the Acknowledgements section or in the paper itself.



Conflict of interest

All authors are expected to provide disclosures before submission for inclusion in the “Conflict of Interest” statement. Items included in the disclosure statement should cover: consulting fees or paid advisory boards (for the past three years or the known future), equity ownership/stock options (publicly or privately traded firms, excluding mutual funds), lecture fees when speaking at the invitation of a commercial sponsor (for the past three years or the known future), employment by the commercial entity that sponsored the study, grant support from industry, patents and/or royalties, expert witness, and other activities performed for a commercial sponsor.

Should any conflict of interest arise, it should be reported while submitting the manuscript in a dedicated section of the submission procedure in our Editorial System, not in the Acknowledgements section or in the paper itself.

 

Declarations

All manuscripts must contain the following sections under the heading 'Declarations':

  • Data availability

The datasets generated and/or analyzed during the current study are available from the corresponding author on reasonable request.

  • Consent for publication

We often find that authors have confused consent for publication with consent for participation in their study. For the purpose of this document, "consent" refers to consent to publish personal information about an individual, and not informed consent for participation in a study.

If any of the sections are not relevant to your manuscript, please include the heading and write 'Not applicable' for that section.

 

Copyright declaration

The Author/Author(s) declare that:

a) they are copyright holders to the scientific work/publication;

b) they are entitled to dispose of copyright for the purposes of the concluded license/publishing agreement with the Wroclaw Medical University;

c) they created the work/publication on their own;

d) the work/publication does not violate the rights of third parties.

In the event that a third party files a claim against Wroclaw Medical University as a result of the inconsistency of the Author's statements or assurances, the Author is obliged to immediately cover the full amount of all damages, costs, and expenses incurred by Wroclaw Medical University in connection with such claims. This includes damages and costs awarded by a competent court or resulting from the content of the settlement concluded with the aggrieved party, as well as costs of legal services.

 

Authorship

The authorship should be based on the following criteria:

  • substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work;

  • drafting the work or revising it critically for important intellectual content;

  • final approval of the version to be published.

Authors should meet all 3 above criteria. If a large, multi-center group conducted the research, the group should identify the individuals who accept direct responsibility for the manuscript. The Author submitting a collectively authored manuscript should establish the order of authorship, provide all individual authors of the particular group, as well as provide the group's name. All those designated as authors should meet all criteria for authorship, and all who meet the criteria should be identified as Authors. The contribution of each Author must be documented to the extent to take the public responsibility for appropriate portions, the content and the conflict of interests. Authors who do not meet all 3 criteria of authorship should be acknowledged (prior to their written consent).

All Authors who have made significant contributions should be listed as co-authors and their authorship should be disclosed in accordance with the following list:

A – research concept and design; B – collection and/or assembly of data; C – data analysis and interpretation; D – writing the article; E – critical revision of the article; F – final approval of the article.

Ghostwriting and guest authorship are manifestations of scientific misconduct, and any detected cases will be investigated, including notification of the relevant entities (institutions employing the authors, scientific societies, associations, scientific editors, etc.). Editors require the identification of funding sources of publications, information about contribution to research from institutions, associations and other entities (the rule: financial disclosure). Editors continuously monitor and document any signs of scientific misconduct, especially violations and breaches of ethics applicable in the study.

The order of Authors in the Editorial System is also the order in which the Authors will appear on the title page of the published paper. Therefore, the first Author in the Editorial System will be also considered the first Author of the paper. Before submitting the paper, please check whether the order of the Authors in your manuscript as registered in the Editorial System reflects the order you intend. Changes of authorship following the acceptance of the manuscript for publication are not permitted.

Please note that there can be only 1 first Author and 1 corresponding Author for each manuscript (both functions can be also held by a single person). Polimery w Medycynie – Polymers in Medicine does not permit co-first authorship and co-corresponding Authors for any reasons. However, we offer to mark the names of 2 chosen authors on the first page of the paper with asterisks [*] and to place a disclaimer [X and Y contributed equally to this work] on the same page. 

No information allowing for authors' identification, in particular authors' names, should appear anywhere in the main body of the paper. 

 

Changes to authorship

Before manuscript submission, provide the final and definite list of all authors. If you want to add, remove or change the order of the authors, you can do it only before the manuscript acceptance. Changes of authorship following the acceptance of the manuscript for publication are not permitted. Each change, however, should be always approved by the journal Editor.

To make authorship changes, send to the Editorial Office a document containing the following information:

1) list of original authors;
2) list of current authors;
3) the reason for the change in the author list; and
4) identification of current corresponding author (if the modification includes changing the person fulfilling this role).

The document must also include signed consent from all authors stating that they agree with the addition, removal or rearrangement in the list. In other words, all the original and the current authors must sign it. We require such signatures from all authors, even those who have been added or removed. The document should be sent to the Managing Editor: marek.misiak@umw.edu.pl.

 

Acknowledgements

Include individuals or companies which have assisted with your study, including advisors, administrative support and suppliers who may have donated or given materials used in the study. Funding of the research should be disclosed in Funding sources section, not in Acknowledgements. Conflict of interest should be disclosed in the Conflict of interest section, not in Acknowledgements.

 

Names of countries, cities and institutions

We use the following names of countries:

  • China [not: People’s Republic of China]

  • Turkey [not: Türkiye]

  • Czech Republic [not: Czechia]

  • Turkish Republic of Northern Cyprus (TRNC) [not: Cyprus, if the institution in question is in TRNC and not the Republic of Cyprus]

We use English names of cities, not their original versions [e.g., Mexico City (not: Ciudad de México), Naples (not: Napoli)]. 

We use English names of universities, hospitals, clinics, scientific institutes, and other entities, not their original versions [e.g., National Autonomous University of Mexico (not: Universidad Nacional Autónoma de México)].

Graphical abstract

The journal Polimery w Medycynie – Polymers in Medicine requires graphical abstracts (GAs) for papers accepted for publication. The editorial office does not offer graphic designing or DTP services – the authors have to provide graphical abstracts in a finished form. The GAs should be submitted as a separate file in the submission system.

Requirements regarding graphical abstracts

An extensive paper on GAs was published in Adv Clin Exp Med:

In a blink of an eye: Graphical abstracts in Advances in Clinical and Experimental Medicine

 

Key words

Abstract should be followed by 3–5 key words written in the language of the manuscript and recommended by the Index Medicus Subject Headings (MeSH).

The manuscripts – main text and reference list – should be formatted as follows: Times New Roman 12, spacing 1.5. The main body of the text should not contain names and affiliations of the authors or the abstract. Tables, figures and reference list should be submitted only as separate files and are not to be pasted into the main text. All numbers of the references in the text should be in superscript and without parentheses. Do not number headings or subheadings.

The total number of words in REVIEWS and META-ANALYSES should not exceed 7000 words (including main text, tables and figure legends, and excluding reference list), and 3000 words in ORIGINAL PAPERS (including main text and figure legends, but excluding title page, abstract and references).

We accept up to 10 tables and 10 figures.

The main body of the text (regardless of its type) should consist of the following sections introduced by separate subheadings in the following order:

  • Background/Introduction (at least 1 page long);

  • Objectives;

  • Limitations of the study;

References to literature, figures and tables should be placed in the order of their citation in the text. The Author(s) should not use italics (apart from names of the genes and taxonomy), bold or underlined words in the texts. Please use only generic names of drugs. Laboratory values should be expressed using the International System of Units (SI).

When the study involves humans or animals, please include the disclaimer about the approval of the bioethical committee or about the reason why such consent was waived. When the study involves humans, please include a disclaimer about compliance with the Declaration of Helsinki or about the reason why the Declaration is not applicable, as well as information of informed consent provided by the subjects or lack thereof.

 

Statistical analysis

Please read thoroughly and familiarize yourself with our new statistical guidelines. These requirements are to be followed closely. Each paper which includes statistical analysis results in any form undergoes statistical review by a statistical editor, separately from the peer review. Papers which do not pass this review are not accepted for publication.

 

Units of measure

Laboratory values should be expressed using the International System of Units (Le Système International d’Unités, SI). Temperatures are to be given in degrees Celsius. If conventional units are used, their SI equivalents should be provided in parentheses only at first mention in the text.

Units should be placed after numerical values with a space between – e.g. 20 mL, not 20mL. All numbers (including those lower than 10) should be written using figures, not spelled out (e.g., 4, not four). 

 

Laboratory equipment, reagents and software

If any equipment, software, reagents, antibodies or anything else obtained from external entities was used, the following information should be provided:

  • exact model of equipment, full name of assay or reagent, catalog number of antibody, etc.;

  • name of the manufacturer;

  • location of the manufacturer (country and city (not state/province - e.g., Los Angeles, not California);

  • in case of software – exact version of the software (e.g., IBM SPSS v. 24.0);

  • in case of freeware software or databases (like KEGG or Gene Ontology) a direct URL from which the used version of the software can be downloaded is sufficient.

 

Abbreviations

Abbreviations should not be used unless they appear at least 3 times in the text. Nonstandard abbreviations should be avoided. Do not use abbreviations in manuscript titles (except when space considerations require otherwise) or figure legends and table titles. In rare cases, when the abbreviation is more familiar than the expansion, the abbreviation alone can be used (e.g. DNA). All abbreviations used in the text should be explained in the article, not on a separate list.

 

Tables

Tables should be placed in separate files, not pasted into the main body of the text. They should be in an editable format (not inserted as pictures). References to Tables should be placed according to the sequence of citing them in the manuscript. The text should include references to all tables. Allowed formats: doc, docx [not xls or xlsx]. The same data should not be provided twice – both in the text and in the table, but only in the table, while the text should contain only a reference to a given table. Include a brief and self-explanatory title with any explanations essential to the understanding of the table given in footnotes at the bottom of the table. Citations in the tables should be numbered and included in the Reference list. There cannot be empty cells in the table – if no data/information is given, fill in a cell with a hyphen (–).

All abbreviations used in a given table/figure should be explained below it or in the caption, even if a given abbreviation has already been explained in the text.

When you cite references in the tables, you have to provide the numbers of the references also in the table. The references in the tables should be in the order they appear on the reference list. If there are 2 authors, both surnames should be provided. If there are more than 2 authors, surname of the 1st author and et al. should be provided. References in tables should fit into the consecutive numeration of the references in place where a given table is first mentioned.

We accept up to 10 tables (2 tables in Research letters).

 

Figures

We accept up to 10 figures. Overtly complex figures will be divided into smaller ones and the number of figures will be counted again. A single figure can have no more than 6 panels (A–F). One panel means one chart – multiple small charts cannot form one panel.

All elements of each figure must be legible when viewed on an A4 page in a PDF file in full-screen mode, without zooming. Overtly complex figures with multiple charts/graphs combined into one panel cannot fulfill this requirement. Figures of low quality cannot be published, and consequently, papers with low-quality figures will not be published, even if accepted by peer reviewers.

Figures should be placed in separate files, not pasted into the main body of the text. Name your figure files with "Fig" and the figure number, e.g., Fig.1.tiff.

References to Figures should be placed according to the sequence of citing them in the manuscript. The text should include references to all figures.

Each figure should have a concise, self-explanatory caption describing accurately what the figure depicts. Captions for the figures should be placed at the end of the main body of the text. Do not embed the legend in the figure file. When applicable, be sure that both the figure captions and the figures themselves contain corresponding labels for multiple parts. Identify all elements found in the figure in the figure caption; and use boxes, circles, etc., as coordinate points in graphs. If any magnification is used in the photographs, indicate this by using scale bars within the figures themselves. All abbreviations used in a given table/figure should be explained below it or in the caption, even if a given abbreviation has already been explained in the text.

If Authors used in the work any figures, photographs, charts, tables, etc. which are not their work, and are protected by the copyright law, they shall be obliged to provide the Publisher with a written authorization to use such materials issued by the author’s economic rights holders. Identify previously published material by giving the original source in the form of a reference citation at the end of the figure caption.

Please read our technical requirements for figures.

 

References

The references should be consecutively numbered, not prepared in Harvard style. The reference list should be in the order of works being cited in the text, not in alphabetical order.

Do not include references in the abstract or in headings/subheadings.

It is the responsibility of the authors to ensure the accuracy of all references according to AMA citation style. References should be limited only to the most recent positions and directly connected to the presented topic. References should be identified by Arabic numerals (without parentheses) in superscript and numbered consecutively in the order in which they are first mentioned in the manuscript. This also includes references in tables – they should fit into the consecutive numeration of the references in place where a given table is first mentioned. All references from the reference list should be mentioned in the text, consecutively and with no gaps (e.g., Reference 16 cannot appear until reference 15 is mentioned at least once). If references are mentioned in a table, they should also appear in ascending order.

When you cite references in the tables, you have to provide the numbers of the references also in the table. The references in the tables should be in the order they appear on the reference list. If there are 2 authors, both surnames should be provided. If there are more than 2 authors, surname of the 1st author and et al. should be provided. References in tables should fit into the consecutive numeration of the references in place where a given table is first mentioned.

Abbreviations for journal names should be cited according to Index Medicus. If a journal is not listed in Index Medicus, its full name should be given. Reference to articles that are accepted for publication may be cited as "in press", whereas manuscripts that are still in preparation or submitted for publication should be referred to as  “unpublished data”. The abbreviation et al. should be applied when there are more than 6 authors, but only the first 3 authors should be listed in such situations (e.g., Hu X, Chang J, Mao M, et al.).

Please provide DOIs to all positions on the Reference list. If a cited position lacks DOI, please provide PMID. If there is also no PMID, please provide direct URL to the published paper (not to a database), if possible.

Please do not paste the reference list into the main text – it should be submitted only as a separate file.

This journal should be cited in lists as Polim Med.

 

Supplementary material

Supplementary material is peer-reviewed material directly relevant to the conclusion of a paper that cannot be included in the printed version for reasons of space or medium (for example, movie clips or sound files). Supplementary tables and figures must have a separate numbering system from that used for tables and figures that appear in the paper (the first figure displayed should be labeled “Supplementary Figure 1”, the first table  “Supplementary Table 1”, and so on).

The Statistical Editors of our journal require that the supplementary files are always available to the readers. Please deposit them in this free of charge repository:

https://zenodo.org/

and obtain a single DOI number for the whole package. Then, provide us this DOI together with a short description of the contents of the package. Each file should be numbered (Supplementary Table 1, Supplementary Figure 1, etc.) and a one-sentence description of its contents should be provided. We will publish both the description and DOI at the end of the manuscript, as a “Data availability statement” subsection:

Supplementary Table 1. CAPTION.

Supplementary Table 2. CAPTION.

Supplementary Figure 1. CAPTION.

Supplementary Figure 2. CAPTION.

Neither Polim Med nor the publisher of this journal (Wroclaw Medical University) are in any way associated with the Zenodo repository – neither financially nor organizationally. We are simply recommending this entity as a reliable and cost-free third-party data storage opportunity.

 

Originality check

As a part of the initial verification of the manuscript, each text is checked using anti-plagiarism software (iThenticate). Only manuscript with a Similarity Index (SI) lower than 30% will be accepted for further verification – those with SI od 30% or higher will be sent back to authors for rewrite. This applies also to papers being continuations or expansions of previous publications – re-using previously published text, e.g. in the Materials and methods section, is not an accepted solution.

 

Usage of artificial intelligence (AI) tools

These guidelines only refer to the writing process (i.e., generating text using an AI tool), and not to the use of AI tools to analyze and draw insights from data as part of the research process. They do not apply to the use of basic tools for checking grammar, spelling, references etc.

Authors are allowed to use generative AI and AI-assisted technologies in the writing process before submission, but only to improve the language and readability of their paper and with the appropriate disclosure. Applying the technology should be done with human oversight and control, and authors should carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete or biased. AI and AI-assisted technologies should not be listed as an author or co-author, or be cited as an author. Authorship implies responsibilities and tasks that can only be attributed to and performed by humans. Please note that authors are ultimately responsible and accountable for the contents of the work.

Detailed information should be provided in the Materials and methods section. The full prompt used in the production of the work, as well as the AI tool and its version, should be disclosed. Authors are accountable for the accuracy of the work and for ensuring that there is no plagiarism. They must also ensure that all sources are appropriately cited and should carefully review the work to guard against bias that may be introduced by AI. Editors may decline to move forward with manuscripts if AI is used inappropriately.

Authors who use AI-assisted technologies as aids in the writing of the manuscript should note this in the cover letter and in the Acknowledgments section of the manuscript. Moreover, they must disclose the use of generative AI and AI-assisted technologies by adding a statement at the end of their manuscript in the manuscript body (main text) file, at the end of the paper. Such statement will appear in the published work. The statement should be placed in a new section entitled “AI usage in the writing process” and follow this pattern:

During the preparation of this work the author(s) used [NAME TOOL / SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the publication.

If there is nothing to disclose, there is no need to add a statement.

Our journal does not permit the use of generative AI or AI-assisted tools to create or alter images in submitted manuscripts. This may include enhancing, obscuring, moving, removing, or introducing a specific feature within an image or figure. Adjustments of brightness, contrast, or color balance are acceptable if they do not obscure or eliminate any information present in the original. Image forensics tools or specialized software might be applied to submitted manuscripts to identify suspected image irregularities.

The only exception is if the use of AI or AI-assisted tools is part of the research design or research methods (such as in AI-assisted imaging approaches to generate or interpret the underlying research data, for example in the field of biomedical imaging). If this is done, such use must be described in a reproducible manner in the methods section. This should include an explanation of how the AI or AI-assisted tools were used in the image creation or alteration process, and the name of the model or tool, version and extension numbers, and manufacturer. Authors should adhere to the AI software’s specific usage policies and ensure correct content attribution. Where applicable, authors could be asked to provide pre-AI-adjusted versions of images and/or the composite raw images used to create the final submitted versions, for editorial assessment.

 

Anonymous review

All manuscripts will be subject to a process of anonymous editorial review (the name of authors and their affiliations will be disclosed to the reviewers only when the review process is complete). In order to achieve this, the first page and the acknowledgements page will be removed from the manuscripts sent to reviewers. Manuscripts will be sent to at least 2 independent reviewers. The final decision on accepting the manuscript is made by the Editorial Board; reviews are only supporting this decision. The Editorial Board’s final evaluation of each article is based on criteria developed by the Committee on Publication Ethics (COPE).

In their response to peer reviewers and statistical reviewers, the authors should provide a point-by-point response to reviewers' comments and a version of your paper with all changes marked with red color of the modified text or red highlighting of such passages. Moreover, the  “track changes” function in the Word software should be used.

 

Proofs

Authors should keep a copy of their article, as proofs will be sent to them without the manuscript. Corrections to the proofs should be restricted to printer’s errors only. Please read, correct and return the proof to the Editorial Office within 3 working days. Delay in the return of proof may result in publication of the paper without your corrections or may postpone the publication. It is the authors' responsibility to ensure that there are no errors in the proof.

Please mark the corrections in the pdf file using the “comment” option. Please mark the passages that need to be modified. Either changing the contents of the PDF file itself or providing the corrections as a separate list is not considered appropriate. All corrections have to be made using ONLY the “comment” function. Changing anything in the PDF itself renders it unusable for us [this includes both changes to the text and tables/figures, as well as adding watermarks]. It is also unethical because the editors need to be able to track each correction you make.  Do not lock the comments on the proof – we need to be able to remove them.

Please note that since October 1, 2021 after the article is published as ahead of print, it cannot be changed (which encompasses also affiliations and authors’ order). Such stipulation stems from requirements set by scientific databases in which the papers published Polimery w Medycynie – Polymers in Medicine are stored.
