File structure. The Journal's Editorial Office prefers to receive the manuscript as a single complete file with all figures, tables, and any supplementary materials.

Manuscript templates:

• Original research article template,
• Case report template,
• Review article template,
• Reference formatting template.

MANUSCRIPT STRUCTURE

Article title. The title should be short and unambiguous; yet it should reflect research findings and contain keywords. No more than 12 words. Avoid vague titles, be more specific. The title should not contain the commercial names of medicines and equipment. The study type should be included directly in the title, or placed at the end of the title following a colon. Examples include: a single‑center case‑control study; a randomized pilot study; a single‑center retrospective observational study, etc. See information on research types

Authors and their affiliations, indicated by superscript numbers, should be listed under the title on the first page of the manuscript. No more than 10 authors! The order of the authors is decided by the authors themselves. The corresponding author is marked with an envelope symbol in a superscript to the right of their surname.

The abstract must be structured and fully reflect the content of the paper. It should be between 200 and 400 words in length. The abstract should not include newly introduced terms, abbreviations (except for well-known ones), or literature citations.

Keywords. 5–10 words or word combinations which are specific to the study topic, supplementing the terms provided in the title and the abstract. Please use only conventional terms and be very specific. Correct choice of keywords impacts citation of the article. Keywords should be separated by semicolons with no full stop at the end.

Funding. A brief list of funding sources for the results presented in the article, as well as for the publication process itself (e.g., a commercial organization, foundation, or government grant, etc.).

Compliance with ethical principles: indicate the date of the ethics committee meeting and the protocol number; indicate that all participants signed a voluntary consent before participate in the study. If the patient is a child under 14 years of age or an incapacitated patient, the form is signed by a parent or guardian; if the patient is 14–18 years of age, the consent must be signed by both the patient and their legal representative (parent or guardian). Publication of patient photographs is only possible with the consent of the patient (or their legal representative). The only exception is anonymized images that do not contain descriptions revealing the patient's identity. If legal representatives cannot be identified, or in cases of exceptional value to medical practice, publication may proceed. In such cases, it is necessary to explicitly state the absence of consent and confirm that every effort has been made to obtain it.

If research involves working with animals, indicate that the conditions of their keeping and working with them comply with the standards for working with animals. If the study did not require ethics approval, please write about it.

Acknowledgements. An optional note describing the roles and responsibilities of the authors. You may also place acknowledgements here to any individuals or organizations that assisted you in your work. However, the authors should obtain the permission from the people or institutions they would like to address in Acknowledgments.

Potential conflict of interest. An explanation regarding any potential or actual conflicts of interest of the authors. Any affiliations, financial relationships, financial or political interests concerning the manuscript in whole or in part, including employment and other obligations, that could lead to concealment or deliberate distortion of data or adverse interpretation are considered conflicts of interest and must be explicitly stated as such. Please note that conflicts of interest do not preclude publication, whereas failure to disclose them does.

Use of AI tools. In this section, authors must disclose the use of AI tools in preparing the manuscript. Authors must confirm the use of AI, including the name of the AI tool used, the purpose of its use, and the extent of oversight. A statement regarding the use of AI tools promotes transparency and trust among authors, readers, reviewers, editors, and contributors, and facilitates compliance with the terms of use of the relevant AI tool. Basic grammar, spelling, and punctuation checking does not require a statement. In cases where authors use generative AI and AI-assisted technologies during the writing process, these technologies should be used only to improve the readability and language of the work. The application of the technology must be carried out under human control and supervision, and authors must carefully review and edit the output, as AI may generate authoritative-sounding outputs that may actually be incorrect, incomplete, or biased. Authors are ultimately responsible for the content of the work. If AI tools were not used in the preparation of the manuscript, authors must also state this.

Corresponding author. The full name and email address must be provided. This author is responsible for correspondence with the Journal's editorial board on behalf of the co-authors and, subsequently, with the readers.

Text should begin with a brief introduction describing the significance of the article. The full-text manuscript structure should conform to the template.

References. The Journal uses the Vancouver citation style, which requires in-text citations in square brackets, with sources listed in the References section in the order of their appearance. Each source in the Reference list must be placed on a new line and numbered sequentially.

Detailed guidelines for reference formatting are provided in the Template.

The main points to consider when preparing the manuscript for submission are as follows:

• In the Reference list, all works must be listed in the order of citation, NOT in alphabetical order.
• Number of references is limited to 90 for literature reviews; the number of references in the original article should be between 15 and 40. Case reports must include a minimum of 10 references.
• The reference list should include only indexed national and international sources – articles from scientific journals and collections, monographs, patents – preferably, published over the last 5–7 years. However, we assume that older references indicate the absence of interest to the subject matter or the lack of expert knowledge demonstrated by the authors. Self-citing can account for no more than 15% of your work.
• Within the body of the text references should be provided in Arabic numerals enclosed in square brackets.
• It is undesirable to include in the list of references abstracts, dissertations, textbooks, manuals, GOST standards, information from websites, statistical reports, articles in socio-political newspapers, on websites and blogs. If it is necessary to refer to such information, you should include information about the source in a footnote (see the Footnotes section).
• References to articles that have been accepted for publication but have not been published yet should state “in print” in square brackets. The authors should obtain written confirmation that such articles have been indeed accepted for publication. Information from unpublished sources should be marked with the words "unpublished data/documents", and the authors should also receive written confirmation of the use of such materials. References to preprints should state “preprint” in square brackets. Please see examples below.
• International citation systems require that the References section should be included in the English-language part of the article. Accordingly, references to sources should be made not only in the original language but also in the Latin (Roman) alphabet, according to official translations (not by free transliteration). If a source does not provide a ready-made citation for reference lists, it is acceptable to transliterate the title of this source and its authors' names. In this case, the BSI format should be used.
• The use of hyphenation for word breaks (especially DOIs) is prohibited, as this may impede correct indexing in databases.
• Important! Generating reference lists using AI tools is not permitted. If a fake (non-existent) literature source is detected in the reference list at any stage of preparing the article for publication, the editorial board reserves the right to reject the article without consideration. All literature sources used by the authors in the text must be carefully verified: the citation data must correspond to the bibliographic details of the cited article (in the reference list); in-text citations must correspond to the provided references to the literature source.
• It is not recommended to cite articles published in predatory journals (those not indexed and/or excluded from RSCI, SCOPUS), as well as retracted articles.
• Authors are responsible for the accuracy and completeness of their references and for correct text citation.
• If there are fewer than 6 authors, all of them should be mentioned in the bibliographic description. If there are more than 6 authors, only the first 6 should be mentioned, and the rest should be indicated as et al.
• If only editors of a book are mentioned, the editors’ names should be followed by “eds.” or “ed.” in English.
• There should be no commas between authors’ last names and their initials and no full stops after the initials. Do not shorten titles of your citations. Shortened journal titles should correspond to the MedLine catalogue. If the journal is not indexed by MedLine, please provide its full title.
• Bibliographic descriptions of journal articles should state the date of publication, volume and issue of the journal, and page numbers. The last page number should specify only the range that changes, e.g. 433–9 (instead of 433–439) or 189–95 (instead of 189–195).
• References should include DOIs or EDNs. DOIs should be formatted as full https:// links.

Footnotes

• Footnotes are numbered in Arabic numerals and placed page by page. Footnotes may contain: references to anonymous sources on the Internet, references to educational and instructional materials, state standards (GOSTs), reports, abstracts, dissertations (if it is not possible to cite articles published based on the results of dissertation research), laws and regulations, guidelines and recommendations8, articles in socio-political newspapers and magazines, author's comments.
• Such references should be made using the MS Word tool “References” → “Insert Footnote”.
• For laws and regulations, as well as for guidelines and recommendations, the footnote should include the name of the document and its bibliographic description. References to regulatory documents should include up-to-date information.
• Footnotes are numbered sequentially; each footnote has its own unique number. When a source is mentioned again in the text, it is assigned a new sequential number. In other words, one and the same source may appear in footnotes as many times as needed, and be assigned different numbers.
• If the information in a footnote repeats the information in the previous footnote, the authors may replace the full name of the source with «Ibid». In other cases, the authors should give the full name of the source again.
• One footnote may include references to several sources.
• Other requirements and examples of footnotes see the Template.

Tables must be of good quality and suitable for printing. Editable tables are preferred rather than scanned ones or images. All tables must have titles. All abbreviations in should be explained in the notes, even if they have already been introduced in the main text of the manuscript. The data in tables and figures should not duplicate each other. Tables should not contain empty cells. Do not put a period at the end of titles. Tables are numbered with Arabic numerals in the order they appear in the text. If there is only one table in the text, it is not numbered. References to tables are formatted as follows: “Table 3 shows that…” or “It is shown that… (Table 3)”. The table caption includes the sequence number of the table and its title."

The author is responsible for the validity of using tables and figures borrowed from other sources. If using tables and figures borrowed from other sources, it is necessary to accurately indicate the source and type of license of the original publication. If the license is not CC BY, you should obtain and provide the permission from the copyright holder to the editor to publish the borrowed material.

Figures (graphs, diagrams, charts, drawings, and other illustrations created using MS Office) must be high-contrast, clear, and suitable for printing. The amount of graphic material should be kept to a minimum (except in works where this is justified by the nature of the research).

Figure titles should not contain abbreviations. All abbreviations in figures should be explained, even if they have already been introduced in the main text of the manuscript. The data in tables and figures should not duplicate each other. Do not put a period at the end of titles.

Figures, and graphs should be placed after the text in which they are mentioned for the first time, or on the next page.

Figures are numbered sequentially with Arabic numerals in the text. A single figure is not numbered. References to figures are formatted as follows: “Figure 3 shows that …” or “It is shown that … (see Fig. 3)”. The figure caption includes the figure number and its title.

It is centred: Fig. 2. Description of vital processes. There is no full stop at the end of the caption.

Graphs must have their ordinate and abscissa axes labelled, specifying the parameter or variable being measured, the units of measurement, and the scale. Units of measurement must be metric and conform to the International System of Units (SI).

Vector image format is preferable. When preparing graphs, diagrams and other illustrations, it is recommended to use Create.microsoft, Powerpointbase, Slidesdocs templates, and software Microsoft PowerPoint, MagicPlot, bioRender, Piktochart, Venngage, or others.

When creating illustrations, it is important to consider the visual perception of people with color blindness. Instead of using only color to distinguish elements (for example, curves or columns), additional methods should be used, such as shading, numbering, letter designations or symbols.

Raster images (photographs, screen shots and other non-drawn illustrations) must be uploaded in a special section of the article submission form as files in the following formats: *.jpeg, *.bmp, *.gif (*.doc and *.docx – if additional notes are applied to the image). The image must have a resolution of >300 dpi without compression. Image files must be named according to the figure number in the text.

Publication of patient photographs is permitted solely with the written consent of the patient or their legal representative. The exception is cases where the photographs are completely anonymized and do not contain any information that could identify the patient. In the absence of signed consent, the authors are required to state in the manuscript text the fact that all exhaustive measures have been taken to obtain it.

Additional information. The authors may provide a link to supplementary materials (figures, tables, and other files), which are placed in a repository (with their DOIs).

Authors’ contributions. In this section provide an indication of what each contributor to a project did.

At Extreme Medicine, we adhere to the following authorship criteria (developed and described in the ICMJE guidelines):

• 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 reviewing it critically for important intellectual content,
• Final approval of the version to be published,
• Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Apart from being accountable for the parts of the study performed on their own, an author should be able to identify which co-authors are responsible for specific other parts of the work.

In addition, the authors should have confidence in the integrity of the contributions made by their co-authors. All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors.

Persons who do not meet all four criteria should be mentioned in the “Acknoledgements" section.

To indicate the contribution of each author, the editorial board recommends using the Contributor Roles Taxonomy CRediT system, a high–level taxonomy that includes 14 roles of participants, which acts as a tool for recognizing and documenting various contributions of authors to the creation of a manuscript in a transparent, standardized and comprehensive way.

Author information. Information about the authors should be provided in a separate file or after a page break. Details for each author of the article: Full name (initials must be spelled out in full); academic degree, academic title; full name of place of work; full name of position held; email address; ORCID (all authors must be registered in Open Researcher and Contributor ID). Indicate this information for all authors. Be careful when writing surnames in Latin-script letters (if you don’t use the Latin script in your country): this affects the identification of authors in reference databases.

EDITORIAL COMMUNICATION WITH AUTHORS

The journal's editorial office communicates directly with the corresponding author. However, if requested by the authorial team, correspondence can be copied to all co-authors who have provided their email addresses.

The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer-review, and publication process.

The corresponding author typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and disclosures of relationships and activities are properly completed and reported, although these duties may be delegated to one or more co-authors.

The corresponding author should be available throughout the submission and peer-review process to respond to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication.

Although the corresponding author has primary responsibility for correspondence with the journal, the editors may send copies of all correspondence to all listed authors.

All manuscripts submitted to the Extreme Medicine journal undergo an initial screening by the Executive Editor to ensure compliance with formal requirements. At this stage, the manuscript may be returned to the author(s) for revision, with a request to correct errors or supply missing data. The manuscript may also be rejected at this point due to a lack of alignment with the journal’s scope, non-compliance with word count limits, violations of publication ethics, insufficient scientific value, or the inclusion of fabricated references.

Following the initial screening, the editors or Executive Editor assigns the manuscript to a reviewer and specifies the review deadline. The author is notified accordingly. In ambiguous or controversial cases, the Editor may involve additional experts or the Editor-in-Chief in the peer review process.

If the reviewer provides a positive evaluation, the manuscript is passed to the editor to be prepared for publication.

If the reviewers and/or the editors raise queries or request amendments, the author is given up to 7 working days to revise the manuscript. If the revised version is not received within 1 month, the editorial office reserves the right to withdraw the manuscript from consideration, and a notification will be sent to the corresponding author. In such cases, the manuscript may be resubmitted as a new submission, restarting the full editorial and review cycle. The final decision regarding publication is made by the Editor-in-Chief.

The corresponding author of an accepted article will receive the final layout version followed by the page proofs, which they must check and approve in consultation with all co-authors. If no response is received from the corresponding author within 2 working days, the version of the article will be deemed approved.

APPEALS PROCEDURE FOR EDITORIAL AND REVIEW DECISIONS

In the event of disagreement with a reviewer's and/or editor's decision, or with specific comments, authors have the right to appeal the decision. To do so, the author must:

• Revise the manuscript, taking into account the constructive recommendations of the reviewers and editors.
• Provide a reasoned argument clearly outlining their position on the points of contention.

The editors welcome the resubmission of revised materials if the initial rejection was due to the need for substantial additions to the manuscript or the collection of new data. In such cases, the editorial office is prepared to provide detailed clarification on the modifications required for the manuscript to successfully clear the peer review process.

EDITORIAL ACTIONS IN CASES OF PLAGIARISM, DATA FABRICATION, OR FALSIFICATION

In the event that author misconduct, plagiarism, data fabrication, or data falsification is detected, the editorial office is guided by COPE principles.

The Extreme Medicine defines misconduct as any action by a researcher involving the improper treatment of research subjects or the deliberate manipulation of scientific information such that it ceases to reflect the observed research, as well as any behaviour that fails to comply with accepted ethical and scientific standards.

The Extreme Medicine does not classify honest errors or genuine differences in the planning, execution, interpretation, or evaluation of research methods or results as misconduct, nor does it include misconduct that is unrelated to the scientific process.

POLICY ON CORRECTIONS AND RETRACTIONS

Minor Errors. If textual errors and misprints are discovered in an article that do not distort the presented research findings, the editorial office will correct and replace the PDF file of the article. Information regarding the amendments will be published on the article’s webpage and within the file itself.

Article Retraction. A publication will be retracted in the following cases:

• Errors are identified in the text that distort the research findings.
• Plagiarism is detected.
• Author misconduct is discovered involving data falsification and/or fabrication.

Retraction Procedure:

• Initiators: The editorial office, the authors, third-party organisations, or individuals.
• Labelling: The article will be marked with a 'Retracted' watermark or notice.
• Transparency: Information specifying the reason for the retraction will be posted on the website.
• Notification: Details of the retraction will be forwarded to all databases where the journal is indexed.
