INSTRUCTIONS TO AUTHORS

 

Scope and editorial policy

CLINICS publishes peer-reviewed articles of interest to clinicians and researchers in the medical sciences. CLINICS is registered with PubMed Central and SciELO and complies with the policies of funding agencies, such as the Wellcome Trust, the Research Councils UK (RCUK), the National Institutes of Health (NIH), and the German Research Foundation (DFG), which request or require deposition of the published articles that they fund into publicly available databases. CLINICS supports the position of the International Committee of Medical Journal Editors (http://www.icmje.org/) on trial registration. All trials initiated after January 1, 2012 must be prospectively registered (before patient recruitment begins) in a publicly accessible registry. Trials initiated before January 1, 2012 must be registered before submission to our journals. See the ICMJE FAQ regarding trial registration for further details. Visit http://www.who.int/ictrp/network/list_registers/en/index.html for the WHO's list of approved registries. CLINICS suggests: http://www.clinicaltrials.gov/ a user friendly site.

Publication Fees

CLINICS uses a business model in which expenses are recovered in part by charging a publication fee to the authors or research sponsors for each published article. Our 2013 prices are as follows: fast track: US$ 2,000.00; original articles, review articles and rapid communications: US$ 1,200.00. Invited reviews, editorials and letters to the editor: no charge.

* The exchange rate for payments in Brazil-Real is the commercial exchange rate of the day the article is accepted. Clinics uses the Banco do Brasil currency conversion tool.

Manuscripts involving human subjects or the use of laboratory animals must clearly state adherence to appropriate guidelines and approval of protocols by their institutional review boards. Photographs that may identify patients or other human participants of studies shall be acceptable only when a legally valid consent form is signed by the participating patient, other human participant, or his/her legally constituted representative.

 

Manuscript preparation

Manuscripts should be digitalized using a Word *.doc-compatible software program and submitted online in English.
Authors are strongly advised to submit the manuscript in its final form to a spell check for English (US). Submissions with excessive spelling or syntax mistakes as well as articles in which the meaning is not sufficiently clear shall be returned to authors for correction.

Authors are also strongly advised to use abbreviations sparingly whenever possible to avoid jargon and improve the readability of the manuscript. All abbreviations must be defined the first time that they are used. Only terms or expressions that are used at least 5 times throughout the text should be abbreviated. Never use abbreviations that spell common English words, such as FUN, PIN, SCORE, and SUN.

Please make sure to submit your manuscript in the exact format that is described below. Failure to do so will cause the submission to be returned to you during the preliminary examination by the Editorial Office.

Manuscripts are invited in the following categories:

ORIGINAL STUDY: Complete original studies should be submitted in this category. Three sections are offered: basic, clinical, and surgical research. Original studies must conform to the following format:

Title page:

  • Title (up to 250 characters);
  • Running title (up to 40 characters, letters and spaces);
  • Full address of corresponding author only;
  • Authors' names (without titles or degrees). Authors should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Such participation must be declared in this section of the manuscript.

Manuscript:

  • Abstract: Abstracts are limited to 250 words and structured into objectives, method, results, and conclusions. Citations or abbreviations (except internationally recognized abbreviations, such as weights, measures, and physical or chemical abbreviations) are not permitted. Authors are strongly encouraged not to display numerical statistical information but to merely state what is significantly different (or not) between the described parameters.
  • Keywords: For keywords, 3-6 items from the Medical Subject Headings (MeSH) should be used.
  • Introduction: The introduction should set the purpose of the study, provide a brief summary (not a review) of previous relevant studies, and state the new advances in the current investigation. The introduction should not include data or conclusions from the work being reported. A final sentence summarizing the novel finding to be presented is permissible.
  • Materials and Methods: This section should briefly give clear and sufficient information to permit the study to be repeated by others. Standard techniques only need to be referenced.
  • Ethics: When reporting experiments on human subjects, indicate whether the procedures were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975, which was revised in 1983. When reporting experiments on animals, indicate whether the institution's guide, a national research council's guide, or any national law on the care and use of laboratory animals was followed.
  • Results: The results section should be a concise account of the new information that was discovered, with the least personal judgment. Do not repeat in text all the data in the tables and illustrations but briefly describe what these data comprise.
  • Discussion: The discussion should include the significance of the new information and relevance of the new findings in light of existing knowledge. Only unavoidable citations should be included. Citation to review articles are not encouraged in this section.
  • Acknowledgements: This section should be short, concise, and restricted to acknowledgements that are necessary.
  • References in text: CLINICS adopts the Vancouver format. Cite references in the text using Arabic numerals in the order of appearance, within parentheses, (1) after the previous word, with spacing as in this example: "Diabetes (2), hypertension (3,4) and alcoholism (5-9) are complex medical problems (10)."Under exceptional circumstances, authors' names may appear in text: Single author: "Einstein (11) proposed a new theory …", Two authors: "Watson and Crick (12) reported on the structure of …", or Three or more authors: "Smith et al (13) described …""
  • Reference List: Only citations that appear in the text should be referenced. References must be restricted to directly relevant published works, papers, or abstracts. Unpublished papers, unless accepted for publication, should not be cited. Work that is accepted for publication should be referred to as "in press", and a letter of acceptance of the journal must be provided. Authors are responsible for the accuracy and completeness of their references and for correct text citation. Usually the total number of references should not exceed 35. CLINICS adopts the Vancouver format. For up to 6 authors, list all authors. For more than 6 authors, list first 6 authors followed by “et al”.
  • Tables and Figures: The maximum number of tables and/or figures is 6 tables and/or figures.Tables: Should be constructed using the table feature in your word processor or using a spreadsheet program such as Excel. Tables should be constructed using the table feature in your word processor or using a spreadsheet program such as Excel. The tables should be numbered in order of appearance in the text, using Arabic numerals. Each table should have a title and an explanatory legend, if necessary. All tables must be referenced and succinctly described in the text. Under no circumstances should a table repeat data that are presented in an illustration. Statistical measures of variation (i.e., standard deviation or standard error) should be identified, and decimal places in tabular data should be restricted to those with mathematical and statistical significance. Figures: Photographs, illustrations, charts, drawings, line graphs, etc. are all defined as figures. Number figures consecutively using Arabic numerals in order of appearance. Figure legend(s) should be descriptive and should allow examination of the figure without reference to text. Images must be of professional quality and uploaded as *.tiff files. Generally, figures will be reduced to fit one column of text. The actual magnification of all photomicrographs should be provided, preferably by placing a scale bar on the print. Line graphs and charts should never be sent as *.jpeg illustrations. We recommend preparing line graphs and charts as Excel® files and copying these files into a Word *.doc sheet.
  • Comments: Authors should use this space to describe the novelty of their original study. Only the editor of CLINICS has access to this section of the submission.

FAST TRACK ARTICLES: Fast-track articles should follow the same format described above for original studies. The Editorial Office will produce a first-action response in the shortest possible time and will publish accepted fast track articles in the next available issue.

REVIEW ARTICLES: Review articles should cover themes that are relevant to medical practice. Spontaneously submitted reviews are welcome; however, potential authors should bear in mind that they are expected to have expertise in the reviewed field. The sections should be arranged as follows:

  • Title page: As described in the Original Study section.
  • Manuscript: Abstract, keywords and text should be arranged to cover the subject that is being reviewed. If appropriate, the method of reference collection should be described. The use of headings, subheadings, and paragraph titles is encouraged to improve clarity.
