Patient Anonymity and lnformed Consent
It is the Author's responsibility to ensure that a patient's anonymity is carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and following all the guidelines for experimental investigation with human subjects required by the institution(s) with which all the Authors are affiliated.
Submitted manuscript must be an original contribution not previously published (except as an abstract or a preliminary report), must not be under consideration for publication elsewhere, and, if accepted, must not be published elsewhere in similar form, in any language, without the consent of the editor. Each person listed as an Author is expected to have participated in the study to a significant extent. Although the editors and referees make every effort to ensure the validity of published manuscripts, the final responsibility is of the Authors, not of the Journal, its editors, or the publisher.
The editors and the publisher support the principles of the Declaration of Helsinki, and expect the authors of papers submitted to the journal to have obtained ethical consent and followed all legal and regulatory requirements for human experimentation with drugs, including informed consent, applicable in their institution and country.
Type of Manuscript
Succinct and carefully prepared papers are favored in terms of impact as well as readability. Different categories of papers are published. Although Authors are invited to submit manuscripts in particular categories, the editors reserve the right to determine in which category a paper is ultimately published, according to the following criteria.
Original articles: a full-length report of original basic or clinical investigation. An abstract of 200 words maximum is required. This should be comprehensible to readers before they read the article. Avoid abbreviations and reference citations. The rest of the paper should be structured as follows: Introduction, Materials and methods, Results, Discussion, Acknowledgements, References.
Short communications: these must not exceed 1,000 words with no more than one table or illustration and five references. An abstract of 200 words maximum is required. The text should be structured in four parts: Introduction, Methods, Results and Discussion.
Videos: original video articles are accepted after peer-revision. Authors should submit a cover letter, title page, an abstract of 200 words maximum with a clear explanation of the video content, and reference list. Video should be comprehensible to readers and should thus be titled and subtitled with a clear explanation of the procedure reported in the images.
Case reports: reports of novel and interesting clinical or investigational cases. An abstract of 200 words maximum is required. The paper should be structured as follows: Introduction, Materials and Methods, Results, Discussion, Acknowledgements, References.
Editorials: commentaries of articles published in CCE. Editorials are by invitation only.
Letter to the editor: a question or challenge to an article published recently in CCE. Letters should be no longer than 250 words.
Reviews: a comprehensive review of prior publications relating to an important clinical subject. An abstract of no more than 200 words is required. The Introduction should indicate why the topic is important and should state the specific objective(s) of the review. The Conclusion should include the clinical implications and observations regarding the need for additional research. Reviews are generally by invitation only, but also unsolicited systematic reviews and meta-analysis will be considered.
Mini-reviews: these must not exceed 4,000 words with no more than 3 tables or illustrations. An abstract of no more than 200 words is required. Mini-reviews are generally by invitation only, but also unsolicited systematic reviews will be considered.
Commentaries: for topics about technology and ethical aspects. Must not exceed 2,000 words with no more than one table or illustration and 10 references. An abstract no more than 200 words is required. The text can be unstructured or structured under headings of author's choice.
Figures and tables: Authors are required to provide the Publisher with high resolution files of figures and tables (at print size) included in their articles: JPG or EPS or TIFF files, although in some cases other formats can be used. References in the articles to figures and tables will have to be put in round brackets and numbered in a progressive growing order, i.e. (Figure 1) or (Table 1). Figures and tables will have to be completed with titles/captions and eventual legends.
Units/Abbreviations. All measurements should be in SI units with the exception of haemoglobin (g/dL) and blood pressure (mmHg). Original observations recorded in other units should be stated, together with the appropriate conversion factors. Standard abbreviations, without punctuation, are used. Units, Symbols and Abbreviations (1977) published by the Royal Society of Medicine, and SI: The International System of Units (1982) from HMSO provide useful guides. Words must be spelt out on first appearance in both summary and text. Abbreviations, used sparingly, should follow the first full spelling, in parentheses.
References (Vancouver style): References in the articles should be numbered in a progressive growing order and indicated by Arabic numbers put in round brackets. At the end of an article all of the references have to be listed in the same order they appear in the text. Examples are given below:
