SIGNA VITAE publishes papers covering adult, pediatric and neonatal intensive care, as well as emergency medicine. SIGNA VITAE will consider for publication:

  • Review articles
  • Original articles
  • Short reports
  • Letters to the editor

Case reports will be considered only in exceptional circumstances and if they cover an outstanding medical condition or achievement in treating such a condition.

Editorial commentaries, book reviews, and notices of meetings are also published occasionally.

Short reports and Case reports should contain up to 1000 words, 10 references and 1 to 2 tables or figures. Letters to the editor that discuss a recent SIGNA VITAE article should contain up to 500 words and 5 references.

Manuscripts submitted for publication should be accompanied by a letter to the Editor-in-Chief, signed by all authors. The letter should contain the statement that the manuscript has not been submitted elsewhere for publication, and that the authors have contributed significantly in executing the study and/or preparing the manuscript. If the article is accepted for publication, a Conflict-of-Interest Statement will be requested.

Manuscripts should be written in English. American or British English can be used but should be applied consistently throughout the article. Prior to submission, manuscripts should preferably be edited by native English speakers.

Statement of Human Rights

Manuscripts describing human research must contain the statement that the study was approved by the relevant Institutional Review Board (IRB). The IRB approval of the study protocol, as well as consent procedures required by the IRB, should appear at the beginning of the Methods’ section. The research should be in accordance with the Helsinki Declaration of 1975, as revised in 2010.

Conflict-of-Interest Statement

At the time of submitting a manuscript each author is required to write a statement of potential financial disclosure related to him or herself. The disclosure pertains to financial relationships with manufacturers that have an interest in the subject matter of their manuscript. Conflict of interest refers to both personal fees received from manufacturers and funds donated to the authors’ departments.

Statement of Informed Consent

Patients’ names, initials, hospital numbers or photographs should be omitted, unless they are considered essential. The patient (or parent or guardian) should give written informed consent for publishing any personal material.

Peer Review Policy

All articles submitted to SIGNA VITAE are reviewed immediately by the Editorial Board. Articles that do not meet the standards of the journal will be declined without further review, while the remaining articles will usually be sent to two external experts in the field. The decision of the external reviewers can be expected within 5 weeks of submission. Authors are not given the names of the reviewers of their article. Editorial Board members and reviewers need to declare any conflict of interest they may have in reviewing a manuscript. The Editors make the final decision on the manuscript. Authors who have any objection to the decision of the Editors are welcome to approach the Editorial Board with their appeal.

Specialist statistical reviewers are involved whenever the content of the manuscript requires their collaboration.

Statistical Methods

List the test used and relate them to specific data analysis. For parametric methods, normality, shape of distribution and appropriate sample or number of cases in each group must be tested, for example in t-test or ANOVA analysis. Nonparametric methods should be used to compare groups with small number of cases and when the distribution of the dependent variable is not normal. Exact methods should be used as extensively as possible in the analysis of categorical data.

Results should be presented with only as much precision as is of scientific value. Descriptive statistics such as measures of central tendency could be presented with only one decimal place but standard deviations with two decimal places. Measures of association, such as odds ratios and other statistical values such as t-value or F-value should ordinarily be reported to two decimal places whereas P value must be presented with three decimal places. P values smaller than 0.001 should be reported as P<0.001.Each table and figure should be put on a separate sheet of paper. Each table in the paper should be self-explanatory, with an adequate title, legend, and logical presentation of data. Please, do not present the same data in more than one way: present them in a table OR a figure.
