Open Access
|
Brazilian Journal of Nephrology follows the Open Access model, allowing unrestricted virtual access (including the absence of financial barriers) to all scientific content published by the journal. Open access is the condition in which the copyright holder of an academic work grants usage rights to third parties by using an open license (Creative Commons Attribution, CC-BY 4.0), allowing immediate free access to the work and authorizing any user to read, download, copy, distribute, print, search, or link the full texts of articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose. |
Compliance with Open Science
|
BJN is an open-access journal that follows the Gold Open Access model. All submitted manuscripts must be accompanied by the Open Science Compliance Form (https://www.scielo.org/pt-br/sobre-o-scielo/metodologias-e-tecnologias/formulario-sobre-conformidade-com-a-ciencia-aberta/), allowing authors to indicate the alignment of their study with Open Science practices. BJN accepts articles previously deposited in public repositories, provided that full deposit information is included in the Cover Letter. In addition, the journal encourages authors to make research data available in external repositories, promoting greater transparency and enabling data reuse when it is not feasible to include them directly in the article. Since 2025, published articles include the names of the Editor-in-Chief and Associate Editor responsible for overseeing the peer review process, reinforcing editorial transparency and providing clarity regarding the coordination of each manuscript. |
Publication Ethics
|
BJN adheres to ethical and international standards of scientific publishing and aligns with the recommendations of the Committee on Publication Ethics (COPE) (https://publicationethics.org/), the EQUATOR Network (https://www.equator-network.org/), the International Committee of Medical Journal Editors (ICMJE) (https://www.icmje.org/), and the Guide to Good Practices for Ethics in Scientific Publishing (https://wp.scielo.org/wp-content/uploads/Guia-de-Boas-Praticas-para-o-Fortalecimento-da-Etica-na-Publicacao-Cientifica.pdf). In accordance with the Declaration of Helsinki (1975), revised in 2024 (https://www.wma.net/wp-content/uploads/2018/07/DoH-Oct2004.pdf), any study involving human subjects must receive prior approval from the institutions responsible for the research. For experiments involving animals, authors must indicate that applicable institutional and national guidelines for the care and use of laboratory animals were followed. All submissions must include a Cover Letter, which may be signed digitally or in handwritten form by the corresponding author and must obligatorily include the ethical approval protocol number of the study. A template of the letter is available in English for download: https://www.bjnephrology.org/wp-content/uploads/2026/01/BJN_Cover_Letter.docx. All submitted manuscripts must be original and may not be under simultaneous consideration by another journal. To ensure the originality and integrity of the research, BJN uses the iThenticate software (https://www.ithenticate.com/) for plagiarism screening. The concepts, statements, and results presented in the manuscripts are the sole responsibility of the authors. |

The Brazilian Journal of Nephrology (BJN) is the official journal of the Brazilian Society of Nephrology (SBN), dedicated to publishing relevant research in nephrology, covering basic, clinical, and applied research. As a scientific communication vehicle, BJN aims to promote the dissemination of scientific knowledge, contribute to the advancement of clinical practice, and serve as a bridge between the nephrology community in Latin America and other regions of the world. |
Preprints
|
The Brazilian Journal of Nephrology (BJN) accepts the submission of manuscripts previously deposited in preprint repositories, such as medRxiv (https://www.medrxiv.org/), Preprints.org (https://www.preprints.org/), SciELO Preprints (https://preprints.scielo.org/), and EmeRI (https://preprints.ibict.br/). In such cases, authors must report in the Cover Letter the full deposition details, including the direct link to the preprint, DOI number (if available), and date of deposition. After publication of the final version of the article, the corresponding author must update the record in the repository, including the complete reference of the publication, the link to the journal website, and the article DOI. Works previously published in full or in part in journals, books, or websites are not accepted for submission. Conversely, articles available in conference proceedings, dissertations, theses, monographs, or other academic works are not considered prior publications, but their origin must be declared in the Cover Letter. Manuscripts deposited in preprint repositories follow the same editorial workflow as those submitted directly to the journal and receive identical treatment. All articles undergo peer review, ensuring scientific rigor and quality. When a peer-reviewed version of the manuscript has been published in a journal, BJN recommends that this version be cited in the references in place of the preprint. The preprint should be cited only when a published, peer-reviewed version is not yet available. |
Peer Review Process
|
All manuscripts submitted to BJN undergo an initial assessment to verify their adherence to the journal’s scope, compliance with formal aspects, and adherence to editorial guidelines. Works that fail to meet these requirements or lack all documents required in the Instructions for Authors are returned to authors for correction before proceeding to subsequent evaluation stages. During this stage, similarity verification is performed using iThenticate software, ensuring the originality of the manuscript and preventing plagiarism. This analysis applies to submissions to the Original Article, Review Article, Brief Communication, and Guidelines/Consensus sections. If reports indicate similarity above 20% or passages requiring adjustments, authors will be notified and instructed to make the necessary corrections. Manuscripts with excessive redundancy will be rejected. Other sections (Editorials, Update Articles, Perspective/Opinion, Images in Nephrology, Clinicopathological Cases, and Letter to the Editor) do not undergo this verification. Manuscripts approved in the pre-evaluation proceed to the desk review stage, conducted by up to two members of the Scientific Editorial Team, who assess originality, topic relevance, and methodological quality according to minimum standards adopted by the journal. Approximately 40% of submitted manuscripts are rejected at this stage. Manuscripts meeting the desk review criteria are sent to an Associate Editor, who selects external reviewers, obtaining at least two expert evaluations. Based on reviewer comments and the Associate Editor’s recommendations, the Editor-in-Chief decides whether to:
The deadline for submitting the revised manuscript is 20 days for minor revisions and 30 days for major revisions. Revised versions are returned to external reviewers, who assess whether recommendations from the first review round were addressed. After analyzing the reviewers’ reports and final comments, the Editor-in-Chief may accept the manuscript, request additional revisions, or reject it. BJN adopts a single-blind peer review model in which reviewer identities are kept confidential, while author identities are disclosed to reviewers. On average, approximately 50% of manuscripts undergoing peer review are rejected. The average duration of the review process is three months but may extend depending on topic complexity and reviewer availability. To increase editorial transparency, as of May 2025, published manuscripts include the names of the Editor-in-Chief and Associate Editor responsible for overseeing the peer-review process. |
Open Data
|
BJN encourages authors to openly share data, code, methods, and other materials supporting their studies but not included in the articles. Sharing these resources contributes to greater transparency, reproducibility, and research reliability, as well as facilitating reuse and scientific collaboration. Depositing data in trusted repositories such as Zenodo (https://zenodo.org/), Figshare (https://figshare.com/), and OSF (https://osf.io/) is recommended to ensure accessibility and long-term preservation. To support the adoption of open science practices, we recommend consulting the following materials:
|
Article Processing Charges
|
Authors are exempt from article processing charges (APC – Article Processing Charge) and from any cost related to manuscript submission or publication. The journal’s expenses are primarily funded by the Brazilian Society of Nephrology (SBN). Additionally, SBN, in partnership with the Editorial Team, actively seeks complementary funding sources to ensure the journal's ongoing operation and sustainability. |
Ethics Policy and Misconduct, Errata, and Retraction
|
The Brazilian Journal of Nephrology (BJN) adopts editorial practices aligned with the guidelines of the International Committee of Medical Journal Editors – ICMJE (www.icmje.org), the Committee on Publication Ethics – COPE (www.publicationethics.org), the Equator Network (www.equator-network.org), and the Best Practice Guidelines for Strengthening Ethics in Scientific Publication (https://wp.scielo.org/wp-content/uploads/Guia-de-Boas-Praticas-para-o-Fortalecimento-da-Etica-na-Publicacao-Cientifica.pdf). Cases involving plagiarism, self-plagiarism, data falsification, misconduct in human subjects research, duplicate publication, or violation of authorship criteria are evaluated according to COPE protocols. When misconduct is confirmed, the journal may adopt measures such as article retraction, following COPE and Best Practice Guidelines, and formally notify the authors, their institutions, and relevant ethics committees. When justified, a temporary embargo on new submissions by the involved authors may be applied. Regarding corrections to already published articles, BJN adopts measures proportional to case severity: errata are used to correct material errors that do not affect scientific integrity (Errata Publication Guide – https://wp.scielo.org/wp-content/uploads/guia_errata.pdf); retractions are applied in cases of confirmed misconduct and are published clearly and formally (Retraction Publication Guide – https://wp.scielo.org/wp-content/uploads/guia_retratacao.pdf), with notification to all involved parties. |
Conflict of Interest
|
Public trust in the peer review process and the credibility of published articles depend, in part, on how conflicts of interest are managed during manuscript preparation, peer review, and editorial decision-making. A conflict of interest exists when an author (or the author’s institution), reviewer, or editor has financial or personal relationships that inappropriately influence (bias) their actions (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships may range from those with negligible potential to those with significant potential to influence judgment, and not all relationships necessarily represent a true conflict of interest. A potential conflict of interest may exist regardless of whether the individual believes that the relationship affects their scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, and paid expert testimony) are the most easily identifiable conflicts of interest and are the most likely to undermine the credibility of the journal, the authors, and science itself. However, conflicts may also arise for other reasons, such as personal relationships, academic competition, and intellectual passion. BJN policy requires that all individuals involved in the editorial process — authors, reviewers, and editors — disclose any financial or non-financial interests that could be interpreted as real, potential, or perceived conflicts of interest. Authors must report, in the Cover Letter, any financial relationships or commitments undertaken within the past 36 months. Reviewers must indicate conflicts of interest in the manuscript evaluation form available in the ScholarOne system. Editors-in-Chief and Associate Editors must also declare potential conflicts before assuming responsibilities in the editorial process. Additional information on conflicts of interest is available in Disclosure of Financial and Non-Financial Relationships and Activities, and Conflicts of Interest (ICMJE): https://www.icmje.org/recommendations/browse/roles-and-responsibilities/author-responsibilities--conflicts-of-interest.html. |
Use of Similarity-Checking Software
|
Manuscripts submitted to the following sections — Original Article, Review Article, Brief Communication, Guidelines and Consensus — undergo similarity checking using the iThenticate software before peer review. The report allows identification of redundancy, plagiarism, or inappropriate use of excerpts from other works. Manuscripts with similarity above 20% or with passages requiring adjustments are returned to authors for revision, while cases of excessive redundancy or evidence of plagiarism result in immediate rejection. Manuscripts submitted to the Editorials, Update Article, Perspective/Opinion, Clinicopathological Cases, Images in Nephrology, and Letter to the Editor sections do not undergo similarity checking. |
Adoption of Software and Artificial Intelligence
|
Authors may use tools and resources, including artificial intelligence, to support the review and translation of their manuscripts, provided that such use is transparent. The use of these technologies must be declared at the end of the manuscript, in a specific section entitled “Use of Artificial Intelligence Tools.” Artificial intelligence models are not considered authors, and full responsibility for the accuracy, integrity, and originality of the generated or modified content lies entirely with the authors. For further information, please refer to the Guide on the Use of Artificial Intelligence Tools and Resources in Research Communication by the SciELO Network: https://wp.scielo.org/wp-content/uploads/Guia-de-uso-de-ferramentas-e-recursos-de-IA-20230914.pdf. |
Sex and Gender Considerations
| BJN adopts the SAGER guidelines, which provide direction on the appropriate inclusion and reporting of sex (biological) and gender (social and cultural) in the planning, analysis, and interpretation of studies. The complete document is available at: https://www.equator-network.org/reporting-guidelines/sager-guidelines/. |
Ethics Committee
|
At the time of submission, authors must indicate in the Cover Letter the protocol number of approval by the responsible Ethics Committee. When ethical approval is not required, the justification for the exemption must be presented in the same letter. For manuscripts involving experimental investigations with human participants or animals, ethical approval must be reported at the end of the text, in a specific section entitled “Ethical approval,” including the name of the responsible institutional committee and the corresponding approval number. In addition, a consent form must accompany all photographs and/or videos of patients in which identification may be possible. Information that allows patient identification—such as names, initials, or hospital record numbers—must not be published in descriptions, images, or pedigrees, unless essential for scientific purposes and only with the patient’s or legal guardian’s free and informed consent. It should be recognized that complete anonymity cannot be guaranteed; therefore, when there is any doubt regarding the possibility of identification, informed consent must be obtained. Masking the eye region in photographs is not considered an adequate method of anonymization. Any alterations made to preserve anonymity must not distort the scientific meaning of the data. The obtaining of informed consent must be declared at the end of the manuscript, in a specific section entitled “Informed consent.” |

| The Brazilian Journal of Nephrology (BJN), the official journal of the Brazilian Society of Nephrology (SBN), is dedicated to publishing relevant research in all areas of nephrology, including basic, clinical, and applied investigation. The journal accepts different types of manuscripts, such as editorials, original articles, review articles, update articles, perspective/opinion pieces, brief communications, guidelines and consensuses, clinicopathological cases, images, and letters to the editor. |
Accepted Document Types
|
EDITORIAL
A critical and in-depth commentary prepared in response to an invitation from the Editor and/or submitted by a person with notable expertise on the subject.
ORIGINAL ARTICLE Original articles must present unpublished research results and constitute complete studies containing all relevant information so that readers may reproduce the study or evaluate its results and conclusions. They are presented in one of two sections: basic research and clinical research. For clinical research, manuscripts are classified into six nephrology disciplines:
a) Acute Kidney Injury; Authors must follow the SAGER guidelines for the proper reporting of sex (biological) and gender (social and cultural) in study planning, analysis, and interpretation (https://www.equator-network.org/reporting-guidelines/sager-guidelines/). The manuscript must include:
REVIEW ARTICLE Reviews are preferably invited by the Editor, addressed to specialists in a specific area. Their purpose is to summarize and critically evaluate the existing knowledge on a specific topic, commenting on studies by other authors and using an extensive reference base or, occasionally, responding to spontaneous demand on a specific subject. The manuscript must include:
UPDATE ARTICLE Covers current topics relevant to clinical practice and are less comprehensive than review articles. These papers should preferably be prepared in response to an invitation from the Editor and, occasionally, through spontaneous submission. The manuscript must include:
PERSPECTIVE/OPINION Preferably invited by the Editor for a specialist in the field, aiming to broadly present and discuss scientific issues in nephrology. This type of article must be written by experienced researchers in the field or by specialists of recognized competence. The manuscript must include:
BRIEF COMMUNICATION A brief communication is a report on a single topic, concise but definitive. As with original articles, these manuscripts must present unpublished material, though less substantial and of particular interest in nephrology, presenting preliminary results or findings of immediate relevance. The manuscript must include:
CLINICOPATHOLOGICAL CASES These simulate the gradual emergence of information or developments in clinical practice and describe how clinicians or clinical teams reason and respond at each interaction, with discussion of the history, physical examination, laboratory findings, imaging studies, pathological findings, and/or management strategies. The manuscript must include:
IMAGES IN NEPHROLOGY
Present content of educational value. Images or videos must be accompanied by a brief case description, as well as the clinical interpretation and differential diagnosis for the reader. Format 1
Format 2
LETTER TO THE EDITOR The manuscript may be a comment on published material or may present new data or clinical observations. All authors (maximum of three) must sign the letter. The manuscript must include:
BRAZILIAN SOCIETY OF NEPHROLOGY The Brazilian Journal of Nephrology (BJN) accepts the submission of documents from the Brazilian Society of Nephrology, including clinical guidelines, consensus statements, recommendations, and other official documents, with the aim of supporting clinical practice and healthcare professionals’ decision-making. Clinical Guidelines These compile relevant evidence on a specific topic, providing support for healthcare professionals in assessing the risks and benefits of diagnostic, therapeutic, or laboratory procedures.

GENERAL OVERVIEW
|
The table below presents a summary of the requirements defined for each type of contribution. Failure to meet the requirements indicated in this table may result in the manuscript being returned for modification and may delay the review process.
|
Submission and Publication Language
|
The Brazilian Journal of Nephrology (BJN) will accept manuscripts exclusively in English starting in March 2025, and the entire peer review process will be conducted in this language. With this change:
This policy aims to increase the journal’s international visibility, strengthen its global positioning, and maximize the reach of published articles within the international scientific community. To support authors in this process, translation and English writing support tools — including artificial intelligence–based applications — may be used, provided that such use is properly declared in the manuscript. After final acceptance, the journal will carry out language editing in English and Portuguese, ensuring clarity, linguistic accuracy, and editorial consistency. DOI Number All articles published in the Brazilian Journal of Nephrology (BJN) will receive a DOI (Digital Object Identifier), ensuring unique identification, traceability, and persistent access to published content. Clinical Research Reporting The Brazilian Journal of Nephrology (BJN) adopts the guidelines of the Equator Network (https://www.equator-network.org/reporting-guidelines/) to ensure methodological rigor and transparency.
Systematic reviews and meta-analyses must follow PRISMA 2020 (https://www.equator-network.org/reporting-guidelines/prisma/), observational studies must follow STROBE (https://www.equator-network.org/reporting-guidelines/strobe/), and clinical trials must follow CONSORT (https://www.equator-network.org/reporting-guidelines/consort/). Industry-funded trials must state in the Cover Letter that investigators had full access to the data, the right to publish, and the possibility of conducting independent analyses. Author Contributions
BJN adopts the CRediT Taxonomy to ensure transparency in authors’ contributions. The CRediT Taxonomy details the different roles that may be assigned to each author (https://credit.niso.org/). Sex and Gender Issues BJN adopts the SAGER guidelines, which provide recommendations for the appropriate inclusion and reporting of sex (biological) and gender (social and cultural) in study design, analysis, and interpretation. The full document is available at: https://www.equator-network.org/reporting-guidelines/sager-guidelines/. |
Manuscript Preparation
|
Manuscript submission to the Brazilian Journal of Nephrology (BJN) is carried out exclusively online through the following link: https://mc04.manuscriptcentral.com/jbn-scielo. Manuscripts must be submitted in English, and simultaneous submission to another journal, in whole or in part, is prohibited. BJN considers duplicate or fragmented publication of the same study a serious ethical violation. To ensure academic integrity, the journal uses the iThenticate tool for plagiarism detection. If plagiarism is identified, BJN follows the guidelines of the Code of Conduct and Best Practice Guidelines for Journal Editors of the Committee on Publication Ethics (COPE) (http://publicationethics.org/). All authors must link their ORCID registration number (https://orcid.org/) to the profile created in the BJN submission system. Manuscript submission must be accompanied by the following documents (via the system – Step 2: File Upload):
