Manuscript submissions
Authors are requested to send their original manuscript and figures via e-mail to mgassull.germanstrias@gencat.net,
or ecabre.germanstrias@gencat.net together with a covering letter which should be signed by the corresponding author on
behalf of all authors, and should include:
- A statement that all authors have made substantial contributions to all of the following:
(1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article
or revising it critically for important intellectual content, (3) final approval of the version to be submitted. The specific contribution of each author to the work should also be listed in the Acknowledgement section. All contributors who do not meet the criteria for authorship
as defined above should also be listed in the Acknowledgements section. Examples of those who might be acknowledged include a person
who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose
whether they had any writing assistance and identify the entity that paid for this assistance.
- A statement that the manuscript,
including related data, figures and tables has not been previously published and that the manuscript is not under consideration elsewhere.
- A statement of disclosure of financial conflict of interest for all authors. Examples of potential conflicts of interest include
employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other
funding. These statements will be treated confidentially, although a general statement regarding any conflicts will be published.
- The names and contact addresses (including e-mail) of 3 potential reviewers that have not been involved in the design, performance
and discussion of the data and are not a co-worker. You may also mention persons who you would prefer not to review your paper.
Role of the funding source
All sources of funding should be declared as an acknowledgement at the end of the text. Authors
should declare the role of study sponsors, if any, in the study design, in the collection, analysis and interpretation of data; in the
writing of the manuscript; and in the decision to submit the manuscript for publication. If the study sponsors had no such involvement,
the authors should so state.
Randomised controlled trials
All randomised controlled trials submitted for publication in
JCC should include a completed
Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement
website at  http://www.consort-statement.org and for more information. JCC has adopted the proposal from the International
Committee of Medical Journal Editors (ICMJE) which require, as a condition of consideration for publication of clinical trials, registration
in a public trials registry. Trials must register at or before the onset of patient enrolment. The clinical trial registration number
should be included at the end of the abstract of the article. For this purpose, a clinical trial is defined as any research project that
prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical
intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g. phase
I trials) would be exempt. Further information can be found at http://www.icmje.org .
Ethics
Work on human
beings that is submitted to JCC should comply with the principles laid down in the Declaration of Helsinki; Recommendations guiding physicians
in biomedical research involving human subjects. Adopted by the 18th World Medical Assembly, Helsinki, Finland, June 1964, amended by
the 29th World Medical Assembly, Tokyo, Japan, October 1975, the 35th World Medical Assembly, Venice, Italy, October 1983, and the 41st
World Medical Assembly, Hong Kong, September 1989. The manuscript should contain a statement that the work has been approved by the appropriate
ethical committees related to the institution(s) in which it was performed and that subjects gave informed consent to the work. Studies
involving experiments with animals must state that their care was in accordance with institution guidelines. Patients' and volunteers'
names, initials, and hospital numbers should not be used.
Conflict of interest
All authors are requested to disclose any
actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations
within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. See

Figure legends should
be typed double-spaced in consecutive order on a separate sheet, using Arabic numbers (for example, Figure 1). Provide a short title
(in the legends, not on the figure itself) and brief but sufficient information to permit interpretation of figures without reference
to text. Do not exceed 250 words for each legend and provide a key for each symbol used.
Tables should be typed double-spaced,
each on a separate sheet, and contain only horizontal rules. The tables should be numbered in Arabic numerals and contain a brief specific
title. Data presented in tables must be logically and clearly organized; they should be self-explanatory and should supplement, not duplicate
the text. Use superscript capitals starting from "a" and in alphabetical order for footnotes and provide a key for each symbol used.
Figures and photographs should be submitted as separate files. Photographs, photomicrographs, electron micrographs, roentgenograms,
and (professionally drawn) drawings are not required to accompany online submission, but should be submitted as black-and-white high-quality
glossy prints once the manuscript is accepted for publication. A detailed guide on electronic artwork is available on our website: http://www.elsevier.com/wps/find/authors.authors/authorartworkinstructions/ .
- Make sure you use uniform lettering and
sizing of your original artwork.
- Only use the following fonts in your illustrations: Arial, Courier, Helvetica, Times, Symbol.
- Number the illustrations according to their sequence in the text.
- Use a logical naming convention for your artwork files.
- Provide all illustrations as separate files.
Formats
Regardless of the application used, when your electronic
artwork is finalised, please "save as" or convert the images to one of the following formats (Note the resolution requirements for line
drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save the text
as "graphics".
TIFF: Colour or greyscale photographs (halftones): always use a minimum of 300 dpi.
TIFF:
Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (colour or greyscale):
a minimum of 500 dpi is required.
DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office
applications please supply "as is".
Captions: Ensure that each illustration has a caption. Supply captions separately (in
figure legends), not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of
the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Line
drawings: The lettering and symbols, as well as other details, should have proportionate dimensions, so as not to become illegible
or unclear after possible reduction; in general, the figures should be designed for a reduction factor of two to three. The degree of
reduction will be determined by the Publisher. Illustrations will not be enlarged. Consider the page format of the journal when designing
the illustrations. Do not use any type of shading on computer-generated illustrations.
Colour illustrations: Please make sure
that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your
accepted article, you submit usable colour figures then Elsevier will ensure, at no additional charge, that these figures will appear
in colour on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in colour
in the printed version. For colour reproduction in print, you will receive information regarding the costs from Elsevier after receipt
of your accepted article. Please indicate your preference for colour in print or on the Web only. For further information on the preparation
of electronic artwork, please see
http://www.elsevier.com/wps/find/authors.authors/authorartworkinstructions/ .
Please
note: Because of technical complications which can arise by converting colour figures to "grey scale" (for the printed version should
you not opt for colour in print) please submit in addition usable black and white versions of all the colour illustrations.
Units
and Abbreviations
Headings in the body of the paper should be appropriate to the nature of the paper and enhance readability.
Usually, only two categories of heading should be used, but not be numbered. Abbreviations may be used when the term is used at least
three times in the text, but the full term for which an abbreviation stands should precede its first use unless it is a standard unit
of measurement. Abbreviations used only in a table or figure may be defined in the legend. Identify drugs and chemicals used by generic
name (if trademarks are mentioned, manufacturer name and city should be given). The metric system should be used for all measurements
(weight, length, etc.). Temperatures should be expressed as Celsius (centigrade). Metric abbreviations should be expressed in lower case
without periods and with no distinction between singular and plural. Both SI and traditional units may be used. |
