The Brazilian Journal of Nephrology (Jornal Brasileiro de Nefrologia) - ISSN 0101-2800 (online) and 2175-8239 (printed version) - is a quarterly publication (March, June, September and December) of the Brazilian Society of Nephrology (SBN) designed for publication of original works from all relevant areas in the field of nephrology. The online journal has open and free access. In addition to the regular numbers, BJN also publishes annual supplements, primarily addressing clinical practice. The authors are free of submission charge. For selection of articles, originality, topic relevance, and quality of scientific methodology are evaluated, as well as adherence to the adopted editorial regulations. All articles are anonymously peer reviewed, and acceptance notification is normally sent within three months of receipt by the journal. Copyright for articles will be automatically transferred to the Brazilian Journal of Nephrology. The content of the material sent for publication may not be previously published or submitted to other journals. To publish, even in part, in another journal, written approval from the editors is necessary. The concepts and declarations contained in the referred manuscripts are the complete responsibility of the authors.
The Brazilian Journal of Nephrology accepts papers written in Portuguese and English, preferably in English. Papers submitted in Portuguese also requires the author to provide title, description and summary in English, in addition to Portuguese. While papers in English do not require the author to send metadata in Portuguese.

LEGAL AND ETHICAL CONSIDERATIONS
According to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (International Committee of Medical Journal Editors - February 2006).
CONFLICT OF INTEREST
Public trust in the peer review process and the credibility of published articles depend in part on how well conflict of interest is handled during writing, peer review, and editorial decision making. Conflict of interest exists when an author (or the author's institution), reviewer, or editor has financial or personal relationships that inappropriately influence (bias) his or her actions (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships vary from those with negligible potential to those with great potential to influence judgment, and not all relationships represent true conflict of interest. The potential for conflict of interest can exist whether or not an individual believes that the relationship affects his or her scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, and of science itself. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion.
Patients have a right to privacy that should not be infringed without informed consent. Identifying information, including patients' names, initials, or hospital numbers, should not be published in written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that a patient who is identifiable be shown the manuscript to be published. Authors should identify Individuals who provide writing assistance and disclose the funding source for this assistance.
Identifying details should be omitted if they are not essential. Complete anonymity is difficult to achieve, however, and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of patients is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific meaning and editors should so note.
The requirement for informed consent should be included in the journal's instructions for authors. When informed consent has been obtained it should be indicated in the published article.
When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach, and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study. When reporting experiments on animals, authors should be asked to indicate whether the institutional and national guide for the care and use of laboratory animals was followed.
