The primary emphasis of the journal will be clinical and to this end, a number of different types of articles will be published. Each
type will be aimed to provide clinically important information needed to keep up to date with the practice of sleep medicine, written
in a way to foster interdisciplinary understanding and make clinical information accessible to all practitioners.
Article Types Sleep Medicine publishes the following types of articles:
•Original articles dealing with diagnosis, clinical
features, pathophysiology, etiology, treatment (by all relevant modalities, including pharmacological, instrumental, surgical, behavioral,
nutritional), genetics, epidemiology, natural history and prognosis of human sleep disorders will be considered for publication, provided
these have not been previously published except in abstract form or have not been submitted simultaneously elsewhere. Reports may also
include technical aspects of sleep medicine, which are relevant for diagnosis, pathophysiology, etiology, treatment and natural history.
Basic research articles will also be published where they have a direct impact on or shed considerable light on clinical aspects of sleep.
Submission of original articles based on animal or human experimental studies are encouraged, and these articles should include a comment
in the abstract and discussion about the potential clinical relevance of the study. •Review articles on all aspects of
clinical sleep medicine and related basic science that contribute to understanding clinical sleep medicine will be published. Reviews
will be timely, emphasize areas undergoing new development, and include both state of the art reviews and multi-author discussion of
controversial areas. •Controversies in sleep medicine covering dissenting views (pros and cons) will be published periodically.
•Editorials on manuscripts published elsewhere in the journal or on a timely and controversial topic will be published occasionally.
Editorials may contain up to 1000 words and 20 references. •Preliminary or limited results of investigations will be published
as brief communications (up to 1500 words containing 20 or fewer references, one table and one figure). •Well studied
and well written case reports will be published (no structured abstract, up to 1000 words with 10 or fewer references,
one table or a figure). These cases should illuminate important clinical issues, etiology or pathogenesis of a disease or report a new
disease, and unusual but critical aspects of sleep medicine that should be known by all practitioners. •Letters to the Editor
addressing articles appearing in the journal or on other current topics will be published (up to 300 words and five references).
The journal will publish special issues or supplements dealing with proceedings of meetings, workshops or special topics.
•Medical Hypothesis providing an opportunity to address testable hypotheses in sleep medicine based on solid scientific foundation
will be considered for publication. •Historical Issues in Sleep Medicine submissions dealing with sleep-related historical
figures, whether leaders from the past or characters from literature or mythology, will be considered for publication. •Book
reviews are also published. Upon reception of a book from the publisher, it is sent to the book review editor. •Images
in Sleep Medicine submissions should derive from a specific sleep-related clinical situation. Each submission must consist
of high-resolution images (e.g. polysomnographic tracing, actigraphic recording, neuroimaging, etc.) and should be accompanied by a very
brief clinical impression, significance of the findings and figure legend. Readers will be encouraged to foster discussion of any controversial
images. Submissions may contain up to 500 words and five references, and content must be organized by the following headings: 1. Introduction
to the case, 2. Image analysis, 3. Discussion, and 4. References. Submissions not adhering to these guidelines may be rejected without
further consideration. •Clinical Corners will deal with complex and unusual cases of sleep disorders and seek comments
from readers about these cases. We invite potential authors to submit interesting clinical material to this section. •Special
Sections, which focus on such topics as education, guidelines, etc., are published intermittently. •Sleep medicine
also intermittently publishes articles in WebWatch, a section which highlights Internet sources containing information on sleep
medicine. •Also published in the journal are News and Announcements and an International Calendar pertaining to
events in sleep medicine.
Fast Track Publication
Articles for 'fast track publication' can be submitted provided they
fulfil the criteria of containing new and important scientific information. Articles for 'fast track publication' if accepted will be
published within 8 weeks from the received date at Elsevier. Such manuscripts should not exceed 2000 words, 20 references and 3 illustrations
or tables. The Editors reserve the right for final decision whether a manuscript submitted for fast track publication will be so processed
or be submitted through the routine review process.
The journal is published bi-monthly and all manuscripts are peer-reviewed except
proceedings of scientific meetings.
Electronic submission via the Web using EES
The preferred medium of submission to
the accepting Editor is online with the accompanying manuscript, illustrations, tables and annexes. Submission of a paper to Sleep
Medicine is understood to imply that it has not previously been published (except in abstract form) and that it is not being published
elsewhere. Submitted manuscripts should be accompanied by a statement undersigned by all listed authors that they concur with the submission
and that the manuscript has been approved by the responsible authorities where the work was carried out. If accepted, the manuscript
shall not be published elsewhere in the same form in either the same or any other language, without the consent of the Editor and Publisher.
The decision of the Editor is final. The Editor cannot enter into correspondence about a paper considered unsuitable for publication.
Sleep Medicine uses an online, electronic submission system called EES (Elsevier Editorial System). By accessing the following
website http://ees.elsevier.com/sleep
You will be guided stepwise through the creation and uploading of the various
files. When submitting a manuscript to EES, authors need to provide an electronic version of their manuscript. The author should select
a set of classifications from a list, a category designation for their manuscript (original article, review, controversies, letter to
the editor, brief communication, etc.) and may provide keywords and comments to the Editor separately. Details of two reviewers may be
suggested with a submission and can be provided in the comments box or at a later stage when uploading the files for submission.
Authors may send queries concerning the submission process, manuscript status, or journal procedures to the Editorial Office (sleep@elsevier.com).
Once the uploading is done, the system automatically generates an electronic (PDF) proof, which is then used for reviewing. All correspondence,
including the Editor's decision and request for revisions, will be by e-mail.
Manuscript Preparation
Use double spacing
throughout, including the reference section. Manuscripts should be organized as follows: Title page, Abstract, Introduction, Methods,
Results, Discussion, References, Legends, and Tables and Figures. Title Page
Authors' full names, academic or professional
affiliations, and complete addresses must be included on the title page. The corresponding author must be indicated by an asterisk, and
his/her full contact details must be included (telephone and fax numbers and e-mail address).
Abstract
A structured abstract
of approximately 200 words is mandatory at the beginning of each article. The abstract should be organized by: Objective or Background,
Methods, Results, and Conclusions. Review articles and case reports do not need a structured abstract. Keywords
6-8
items must be included on the title page. Authors are encouraged to choose their own key words, but Medical Subject Headings (issued
with the January Index Medicus, latest edition) may be used as a guideline. References
References to literature must be
indicated by Arabic numerals which run consecutively through the paper. Where a reference is cited more than once in the text the same
number should be used each time. Reference style should follow the "Vancouver" style described in the "Uniform Requirements for Manuscripts
Submitted to Biomedical Journals" (published in N Engl J Med 1997;336:309-315). The titles of journals should be abbreviated in conformity
with Index Medicus. The following are sample styles:
[1] Bondi M, Kaszniak A. Implicit and explicit memory in Alzheimer's disease
and Parkinson's disease. J Clin Exp Neuropsychol 1991;13:339-358.
[2] Wechsler D. Wechsler Adult Intelligence Scale. New York: Grune & Stratton, 1976.
[3] Hirst W, Volpe B. Automatic and effortful encoding in amnesia. In: Gazzaniga M, editor.
Handbook of
cognitive neuroscience. New York: Plenum Press, 1984; p. 369-386.
Please ensure that references are complete, i.e. that they include,
where relevant, the author's name, article or book title, volume and issue number, publisher and publisher's location, and page reference.
This journal should be abbreviated as Sleep Med. Figure and Table Legends
Legends should be typed double spaced on a separate
page and numbered with Arabic numerals corresponding to the illustrations. When symbols, arrows, numbers or letters are used to identify
parts of the illustrations, each should be explained clearly in the legend. The legends should permit the figures to be understood with
reference to the text. If the figure has been published previously a credit line should be included. Figures
Figures of
good quality should be submitted online as a separate file. Letters, numbers and symbols should be clear throughout and should be large
to permit photographic reduction.
Be sure that all spelling is correct, that there are no broken letters or uneven type, and that
abbreviations used are consistent with those in the text. Use a label on the back of each figure to indicate the article's running title
and the top of the figure. Do not write directly on the back of photographs. Do not trim, mount, clip or staple the illustrations. Submit
photomicrographs in the final desired size. The colour transparency or negative should be supplied, in addition to colour prints.
Photographs of recognizable persons should be accompanied by a signed release from the patient or legal guardian authorizing publication.
Masking eyes to hide identity is not sufficient.
Colour Reproduction
For colour reproduction in print, a limited number
of colour figures may be printed in the Journal without cost, at the discretion of the Editor, who will make the judgement based on the
academic necessity of the colour illustrations. Otherwise you will receive information regarding the costs from Elsevier after receipt
of your accepted article. For further information on the preparation of the electronic artwork, please see http://www.elsevier.com/artworkinstructions
Tables
Tables should be submitted online as a separate file and should bear a short descriptive title. If a table must
exceed one typewritten page, duplicate all headings on the second sheet. Number tables in the order in which they are cited in the text.
Every column in the table should have an abbreviated heading. Define all abbreviations and indicate the units of measurements for all
values. Explain all empty spaces or dashes. Indicate footnotes to the table with the superscript symbols cited in order as you read the
table horizontally.
Preparation of Supplementary Material (MultiMedia Components)
Elsevier now accepts electronic supplementary
material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting
applications, movies, animation sequences, background datasets, sound clips and more. Supplementary files supplied will be published
online alongside the electronic version of your article in Elsevier web products, including ScienceDirect (http://www.sciencedirect.com).
In order to ensure that your submitted material is directly usable, please ensure that data is provided in one of our recommended file
formats. Files can be stored on diskette, ZIP or Jaz-disk, or CD or DVD (either MS-Windows or Macintosh). Authors should submit the material
in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions
please visit http://elsevier.com/authors.

Conflict
of Interest
Authors must disclose any conflicts of interest when submitting their manuscript. This disclosure requirement includes:
1) research grant of contract support administered through an academic or research institute; 2) personal compensation (as opposed to
institutional salary support) through contract, grants, honoraria, fees, or salary, and whether this is less than or in excess of USD10,000
per year; and 3) personal financial investment, including ownership and equity or other financial holdings, and whether this is less
than or in excess of USD10,000 per year. Failure to reveal this information may cause a published paper to be retracted from publication
in Sleep Medicine.
Phase III Trials
Manuscripts reporting the results of Phase III trials must follow the Consolidated
Standards of Reporting Trials (CONSORT) guidelines. For more information on these guidelines, please refer to:
Begg, C, Cho, M. Eastwood,
S, et al. Improving the quality of randomized controlled trials: the CONSORT statement. JAMA 1996; 276:637-639.
Schulz, KF. The quest
for unbiased research: Randomized clinical trials and the CONSORT reporting guidelines. Ann Neurol 1997; 41:569-573.
Informed Consent/Ethics
of Experimentation
Authors reporting experimental studies on humans must specify that the research received prior approval by
the appropriate institutional review body and that informed consent was obtained from each subject or patient. Manuscripts describing
investigations in animals must clearly indicate the steps taken to eliminate pain and suffering. Authors have a duty to protect their
subjects, animal or human, and to show clearly in their writing a recognition of the moral issues involved.
Purpose and Procedure
Articles submitted for review should meet the following criteria: •Studies of prevention or treatment must meet these criteria:
random allocation of participants to comparison groups; follow-up of at least 80% of those entering the investigation; outcome measure
of known or probably clinical importance. •Studies of prognosis must meet these additional criteria: inception cohort of individuals,
all initially free of the outcome of interest; follow-up of at least 80% of participants until the occurrence of a major study end point
or to the end of the study. •Studies of causation must meet these additional criteria: clearly identified comparison group for
those at risk for, or having, the outcome of interest (e.g. randomized controlled trial, quasi-randomized controlled trial, nonrandomized
controlled trial, cohort analytic study with case-by-case matching or statistical adjustment to create comparable groups, case-control
study); blinding of observers of outcome to exposure (criterion assumed to be met if outcome is objective, e.g. all-cause mortality,
objective test); blinding of observers of exposure to outcomes for case-control studies OR blinding of subjects to exposure for all to
be compared on the basis of both the outcomes produced (effectiveness) and resources consumed (costs); evidence of effectiveness must
be from a study (or studies) that meets the above-noted criteria for diagnosis, treatment, quality assurance, or a review article; results
should be presented in terms of the incremental or additional costs and outcomes of one intervention over another; where there is uncertainty
in the estimates or imprecision in the measurement, a sensitivity analysis should be done.
