General instructions for submission online


OBJECTIVES

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 (Jornal Brasileiro de Nefrologia). 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.

Language

The Brazilian Journal of Nephrology (Jornal Brasileiro de Nefrologia) accepts papers written in Portuguese and English, preferably in English. The submission of manuscripts in both languages ??is stimulated. Papers submitted in Portuguese also requires the author to provide title, description and abstract in English, in addition to Portuguese. While papers in English do not require the author to send metadata in Portuguese.

The manuscript should contain:

  • there is no need for an abstract;
  • text with up to 900 words;
  • no more than 7 references.

Original Articles

These should present unpublished results from research, constituting complete studies that contain all relevant information so that the reader may reproduce the study or evaluate its results and conclusions. They are presented in one of two sections: basic science and clinical research. The manuscripts are classified in six disciplines of Nephrology: a) Acute Renal Injury; b) Chronic Kidney Disease; c) Dialysis and Extracorporeal therapies; d) Epidemiology and Clinical Nephrology; e) Pediatric Nephrology; f) Renal Transplantation.

The manuscript should contain:

  • no more than 40 references.

Review Articles

Reviews are preferably requested to specialists in a particular area (by the Editor). The objective of these articles is to express and critically evaluate the knowledge available on a specific topic, commenting on studies from other authors and using a broad reference base, or on occasion, responding to a spontaneous demand concerning a specific topic.

The manuscript should contain:

  • abstract, not necessarily structured, of no more than 250 words;
