Any article submitted to this journal must follow the guidelines described in this author guide, so it is essential to consult it before submitting manuscripts.
FIRST PAGE
Regardless of the article type or journal section, authors must always include on the first page of the article, in addition to the title, authors, affiliations, and email addresses, statements regarding Ethical Considerations, Informed Consent, Funding, Conflict of Interest, the use of artificial intelligence, and Authorship.
Declarations are required even if the author considers that none exist or are not applicable.
Ethical Considerations. Any article involving experiments with human subjects requires the author to declare that all procedures were conducted in accordance with the Declaration of Helsinki, relevant laws, and institutional guidelines. The reference number of the study’s ethical committee approval must be included in Original Articles involving human experimentation. For Original Articles involving animal experimentation, compliance with the corresponding regulations must also be stated.
Declaration required in the Originals and Brief Originals sections.
Informed Consent. It must be declared that no patient data appear in the article, or if they do, that such data do not violate patient privacy or confidentiality nor allow identification, and that informed consent has been obtained in any case. The privacy rights of human subjects must always be respected.
Appropriate consents and permissions must be obtained when presenting one or more cases without experimentation, or when an author wishes to include personal details, other information, or images of patients or any other individuals in an Elsevier publication. The author must retain written consents and provide Elsevier with copies or proof of consent upon request. To avoid doubt, informed consent is always required in clinical cases, regardless of whether images are anonymized or not, including X-rays. Images accompanied by any patient data always require a declaration.
This declaration is mandatory in all sections except Editorials, Letters to the Editor, and Literature Reviews that do not include Clinical Cases.
Funding. The author must identify who provided financial support for the research and/or preparation of the article and briefly describe the role of the sponsor(s), if applicable, in the study design; data collection, analysis, and interpretation; report writing; and decision to submit the article for publication. If the funding source(s) had no such involvement, this should be declared. This declaration is mandatory in all sections. If none exist, the author must explicitly state so.
Conflict of Interest. Any financial or personal relationships with others that could have influenced the work must be disclosed, even if not directly related to the current manuscript. Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, other funding, travel grants, and participation in courses and conferences as a paid expert. If none of these conditions apply, the statement should read: “Declaration of interest: none.”
If a member of the Editorial Board contributes as an author to a manuscript submitted to the journal, the responsible editor must include the following statement in the conflict of interest section: “As ABC is a member of the Editorial Board of the Journal, they have not participated in nor had access to information regarding the review and acceptance process of this manuscript.”
This declaration is always mandatory. There must be one declaration for each participating author.
Use of Generative Artificial Intelligence in Scientific Writing. Any other use is not authorized. See the description later in these guidelines. This declaration is mandatory whenever such tools are used.
Authorship. Those listed as authors must have made substantial contributions. Changes to authorship or author order are not permitted after submission without prior justification and approval by the Editor-in-Chief. Please refer to the relevant sections described later in these guidelines.
BODY OF THE ARTICLE
Ethical Considerations and Informed Consent must also be declared beyond the first page in cases of experimentation involving animals or humans. If experiments involve animals or humans, certain declarations must be mentioned within the manuscript even though they are also required on the first page. These must always be declared in Originals or Brief Originals (if included), even if the author considers they do not exist or are not applicable.
Ethics and Informed Consent For experiments involving humans or animals, the author must declare in the Materials and Methods section of Originals, Brief Originals, or Case Series, if applicable, that the guidelines on Human and Animal Rights described in the “Ethics in Publication” section of this author guide have been followed. Specifically, if human subjects are involved, authors must confirm that the research was conducted in accordance with the World Medical Association’s Code of Ethics (Declaration of Helsinki). For animals, authors must declare compliance with ARRIVE guidelines or that they are acting in accordance with the Animal Welfare Act on the Care and Use of Laboratory Animals and, where applicable, the Animal Welfare Law. Authors must also declare in Materials and Methods (Original or Brief Original) that they have obtained informed consent and approval from the Clinical Research Ethics Committee (CREC) or corresponding committee without revealing information that could compromise blinded review. Please note that the Spanish Biomedical Research Law establishes that Ethics Committees corresponding to each center must evaluate all biomedical research involving interventions in humans or the use of their biological samples. Appropriate consents and permissions must be obtained when presenting one or more cases without experimentation or when an author wishes to include personal details, other information, or images of patients or any other individuals in an Elsevier publication. The author must retain written consent forms and provide Elsevier with copies or evidence of their acquisition upon request.
