STATEMENT OF ETHICS AND MALPRACTICE IN PUBLICATION

The Peruvian Journal of Gynecology and Obstetrics conforms to the standards of the Committee on Publication Ethics (COPE) statement on ethical behavior and malpractice in scientific publications: https://publicationethics.org/

Academic ethics is a fundamental principle in research and publication, as well as the basis for the reputation of scientists and physicians. To promote academic integrity and the publication of high-quality scientific work, the RPGO issues the following Statement on Ethics and Malpractice in Publication on the ethical behavior of all parties related to the publication of the journal of the Sociedad Peruana de Obstetricia y Ginecología, including the author, the reviewer, and the Editor of the RPGO. The RPGO will be attentive to ensure that commercial needs do not compromise intellectual and ethical standards, and will always be willing to publish corrections, clarifications, retractions, and apologies when necessary.

For Peruvian researchers, it is recommended to comply with the National Code of Scientific Integrity of the National Council of Science and Technology, which establishes the standards of conduct, infractions and sanctions of natural or legal persons who carry out research, in order to adopt good clinical practices and integrity in scientific research: https://tinyurl.com/ttrmokn

1. PUBLICATION AND AUTHORSHIP

Credit for authorship should be based only on: a) substantial contributions to the conception or design of the study; or the acquisition, analysis, or interpretation of data; b) drafting the article or revising it critically for intellectual content; c) approving the final version to be published; and, d) agreeing to be accountable for all aspects of the article, ensuring that all questions related to the accuracy or integrity of any part of the work have been adequately investigated and resolved:https://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html

An author should be able to identify co-authors who are responsible for other specific parts of the article and should be confident in each of their contributions. Contributors who meet fewer than 4 of the above authorship criteria should not be listed as authors but should be acknowledged in the acknowledgments. RPGO does not accept authorship of scientific articles for AI-related technology. AI tools may be useful in the research process or to assist in text generation, but they cannot be credited as authors of the study or the writing of the article.

The corresponding author is the person who assumes responsibility for communicating with RPGO, in a timely manner, during the manuscript submission, peer review, and publication process.

2. AUTHOR RESPONSIBILITIES

All authors contribute significantly to the research and must mark on the Affidavit of Authorship the specific parts of the article to which they have contributed and that all data in the article are true and authentic. Authors are obliged to participate in the peer review process, as well as to provide retractions and correct errors.

Before submitting articles to the journal, authors are recommended to consider what is established by COPE, whose suggestions can be found in the Code of Conduct and Guidelines on Good Practice for Journal Editors: https://publicationethics.org/guidance?f%5B0%5D=type%3A16 These recommendations are adopted by the Editorial Board of the RPGO, and according to its guidelines, the RPGO considers as ethical misconduct: plagiarism, fictitious authorship, changes of authorship, omission of authors, redundant publication, fragmented publication, manipulation of data, undisclosed conflict of interest, fabrication of data, falsification of data, incorrect bibliographic citations (not considering the important ones, self-citation), manipulation of images.

Authors are prohibited from publishing the same research in more than one journal or in any digital media.

A. CONFLICT OF INTEREST

Objectivity and transparency are essential in scientific research and the review process. Researchers and authors, as well as editors and reviewers, should always disclose conflicts of interest when publishing a paper.

The most obvious conflicts of interest are financial relationships such as:

  • Direct: employment, equity interests, grants, patents.
  • Indirect: remuneration, consultancies to sponsoring organizations, mutual funds, payments for expert testimony.

Readers should be informed about who has funded the research and the role of the funders of the research. Conflicts may also arise as a result of personal relationships, academic competition, and intellectual appetite. The best course of action is always full transparency and, when in doubt, disclosure of the problem. Announcing the sources of funding for the study does not imply a conflict of interest.

B. PROTECTION OF INDIVIDUAL INFORMATION

The RPGO protects the confidentiality of individual information (for example, that obtained through the patient-doctor relationship). Patient names, initials, medical record numbers, or general data that allow identifying the persons studied should not be mentioned. Images of patients in the publication of original articles or case reports must have written permission and informed consent. Recognizable features in photographs of identifiable persons will be masked. It is possible to publish without explicit consent if the report is important for public health.

Studies of patients, or of patient or volunteer registries, require approval from an institutional ethics committee, as well as informed consent. If the study deals with aspects of occupational or environmental health, apart from ethical considerations and protection of individual information, approval for dissemination must be obtained from the company where the research was conducted.

C. HUMAN AND ANIMAL EXPERIMENTATION

Articles describing experiments performed on human beings must indicate whether the procedures followed were in accordance with the ethical standards of the Institutional Ethics Committee and the Declaration of Helsinki: https://www.wma.net/es/que-hacemos/etica-medica/declaracion-de-helsinki/

In Peru, the standards to be followed for experimentation on human beings are established in the Regulation of Clinical Trials. The National Institute of Health of Peru is the authority responsible at the national level for ensuring compliance with said Regulation and the related standards that regulate the authorization, execution, and corresponding registration of the trial in the Peruvian Registry of Clinical Trials: https://ensayosclinicos-repec.ins.gob.pe/ Thus, in our country, the authors of clinical trials on human beings require the approval of the National Institute of Health before beginning the experiment. At the request of the RPGO, the author must provide copies of documentation that accredits the authorization.

For animal experimentation, the authors will take into consideration the international standards for the use of experimental animals, in particular those recommended by the Office of Animal Care and Use of the National Institutes of Health of the USA (https://oacu.oir.nih.gov/ ), as well as the guidelines of the institution or national law that governs the care and use of laboratory animals. The animals used must be named in the title, abstract, keywords, and materials and methods. Such experimentation should be thoroughly detailed in the methods section. Experimental research on animals carried out in Peru must be approved by an animal research ethics committee.

3. PEER REVIEW AND RESPONSIBILITY OF REVIEWERS

Peer review or arbitration is a method used to ensure the quality, originality, feasibility and scientific rigor of a research article. Peer review is a mandatory process for all types of articles submitted to the RPGO. Editorials, special articles, symposium articles, controversial articles, and letters to the editor, at the discretion of the Editorial Committee, may also be subject to peer review.

Articles submitted to the RPGO are refereed by evaluators with experience and knowledge of the subject to which the article to be evaluated refers, with the aim that their concepts achieve good judgment and high quality for publication. Preferably, the evaluators are external to the Peruvian Society of Obstetrics and Gynecology and the RPGO.

The requirements to be a reviewer at the RPGO are knowledge of the subject, impartiality, academicism, research, responsibility, and ethics. The reviewers' judgments will be objective, with no conflict of interest regarding the research, the authors or the sponsors of the research; If the opposite occurs, they will not accept the peer review process. The reviewers will treat the articles confidentially. They must highlight the relevant works published and that have not yet been cited.

The reviewers selected by the RPGO do not receive remuneration, but they are issued a certification and are mentioned at the end of the volume to which they contributed. When required by the article, expert reviewers in the field of biostatistics and epidemiology will be appointed. Likewise, for the evaluation of ethical and legal aspects related to Peruvian national legislation, specialists on the subject will be called. The authors of the articles must not suggest their reviewers, since this constitutes a conflict of interest.

Articles submitted to RPGO will be initially evaluated by the Editorial Committee to ensure that they comply with the requirements, including ethical aspects, and will then be subject to peer review. For this purpose, the Editorial Committee invites 2 or more reviewers per article who will anonymously and within 15 days, evaluate the article using an evaluation form provided by the journal. For the information of authors and readers, the content of the evaluation forms is available at: https://spog.org.pe/instrucciones-para-los-autores/  The type of review is double-blind peer review. The referees or reviewers issue suggestions and recommendations on how to improve the article. At the discretion of the Editorial Committee and the methodology reviewers, the authors will be asked for the database used in the methods and results described presented in the article.

4. EDITORIAL RESPONSIBILITY

In accordance with COPE recommendations (https://publicationethics.org/ ), RPGO is committed to meeting the needs of readers and authors, constantly improving the journal, ensuring the quality of published material, defending freedom of expression, maintaining the integrity of the academic record, excluding commercial needs from compromising intellectual standards and, as stated at the beginning, always being willing to publish corrections, clarifications, retractions and apologies when necessary.

5. PRONOUNCEMENT ON PUBLICATION ETHICS

The Editor's decision to accept or reject an article for publication will be based solely on the importance, originality, and clarity of the article, as well as the relevance of the study. The RPGO Editorial Committee is committed to acting without discrimination on the grounds of gender, sexual orientation, religious or political beliefs, ethnic or geographic origin of the authors.

Reasonable procedures are adopted and followed in case of complaints of an ethical nature or conflict, in accordance with the policies and procedures of both RPGO and the Sociedad Peruana de Obstetricia y Ginecología (SPOG), as the case may be, and will give a reasonable opportunity to the authors to respond to the complaint. SPOG guarantees that RPGO subscribes to the principles outlined.

The Editor will not reverse decisions to accept the submission of articles unless serious problems with the submission are identified. New Editors should not override decisions to publish submissions made by the previous Editor unless serious problems are identified.

Misconduct and ethical misbehavior may be identified and brought to the attention of the Editor and the Sociedad Peruana de Obstetricia y Ginecología at any time, by anyone, provided that sufficient information and evidence are provided so that an investigation can be initiated, by email or a letter to the editor. RPGO uses computer software for the purposes of detecting plagiarism and ethical misconduct in scientific publications; it also uses tools such as the one proposed by Nature to evaluate the integrity of publications: https://tinyurl.com/ttrmokn

Retraction policy

RPGO, in accordance with COPE recommendations, will retract articles published in the journal when ethical publication violations are detected, such as: redundant publication, plagiarism, manipulation in the peer review process, reuse of material or data without authorization, violation of copyright, unethical research, undeclared conflicts of interest, among others. The purpose of retraction is to guarantee the integrity of what is published.

Retraction is a mechanism to alert readers about articles that manipulate data, have faulty methodology, or violated ethical aspects, whose findings and conclusions are not reliable, which may occur due to honest error or misconduct in research.

For the retraction procedure, the Editor will immediately inform readers, in the next issue, regarding the identification of the violations and the handling of the case by the Editorial Committee, with the consequent information on the reasons for retraction of the article. Likewise, the PDF file published in both languages will be replaced with the label “retracted” both in the journal’s OJS and in the multiple databases where the RPGO is indexed. The handling of the case towards the authors will correspond to what was previously indicated regarding the measures recommended by COPE and the RPGO when ethical violations are detected.

STATEMENT ON THE USE OF ARTIFICIAL INTELLIGENCE (AI)

AI algorithms can analyze various aspects of a research article, such as its language, structure, originality, and even the quality of its data and methodology. They can help identify potential biases, plagiarism, grammatical errors, and inconsistencies in terminology that human reviewers might miss. But it is not without limitations and the RPGO Editorial Board considers that AI cannot completely replace the human element of peer review, which involves critical thinking, judgment, and expertise in the subject matter.

With specific and detailed instructions, AI has the potential to generate content of a scientific article in its various sections: title, abstract, introduction, methods, data analysis, tables, graphs, discussion, bibliographical references, in a coherent manner, showing the benefits of this technological development. Likewise, AI has potential in the peer review process by complementing human peer review, improving efficiency in the evaluation and compliance of article writing according to international guidelines, with polite language. As a tool for editors, AI shows benefits in the initial review of articles submitted to the journal, allowing for the optimization of editorial processes. The use of AI is not exempt from risks such as: lack of originality, bias, generation of incorrect content, erroneous conclusions, which requires adequate supervision; for reviewers, it has limitations in evaluating and recognizing new, relevant scientific findings, and drawing the correct conclusions from them.

RPGO promotes the use of AI and recognizes the usefulness of its use, provided that it is part of an ethical and transparent process by authors, reviewers, and editors, in accordance with the consensus and recommendations on this topic that have been determined by ICMJE, COPE, and the World Association of Medical Editors (WAME), bodies to which RPGO adheres: https://www.icmje.org/news-and-editorials/icmje-recommendations_annotated_jan25.pdf https://publicationethics.org/guidance/cope-position/authorship-and-ai-tools https://www.wame.org/page2.php?id=106

Likewise, human authors must accept responsibility for the accuracy and integrity of the text submitted to the journal, including the parts produced by AI. Regarding the use of AI in scientific publications, the following considerations show the position of the RPGO Editorial Committee in the editorial process:

  • AI will not be accepted as an author, since it cannot be responsible for the accuracy, integrity, and originality of research, which are essential requirements for authorship.
  • The use of AI is proposed, provided that the circumstances and parts of the article generated are declared, with the warning that what is generated by AI may be irrelevant for the presentation of a manuscript.
  • The use of AI must be written in the Methods section, specifying the use of the tool for content generation, for which the sequences and messages used for the information produced with a chatbot must be submitted, in relation to generated text, as well as generated tables and graphs.
  • If the authors used AI, its use must be stated in the Acknowledgements section.
  • The Editorial Committee will evaluate the relevance of the content generated by AI, establishing a minimum percentage of contribution according to the topic and type of article.
  • RPGO peer reviewers who use AI as part of the evaluation of a manuscript must declare the use of this tool and the manner in which they used it. The use of AI by reviewers will be communicated to the editors and the authors.
  • RPGO Editors will declare the use of AI, if applicable, and the manner in which it was carried out. Likewise, the RPGO Editorial Committee guarantees the confidentiality of the authors' data, refraining from publicly exposing the content of manuscripts in AI where due reliability is not guaranteed.
  • The RPGO Editorial Committee will use AI detection software, in order to guarantee the integrity of the content of the manuscripts.
