Guidance for Authors on the Preparation and Submission of Manuscripts to Blood Coagulation and Fibrinolysis

Note: These instructions comply with those formulated by the International Committee of Medical Journal Editors. For further details, authors should consult the following article: International Committee of Medical Journal Editors. ‘‘Uniform Requirements for Manuscripts Submitted to Biomedical Journals’’ N Engl J Med 1997;336:309–315. The complete document appears at www.icmje.org.

Full details concerning many of the points below, including standard forms, are provided in the guidelines on the journal’s web site (www.bloodcoagulation.com).

Scope

Blood Coagulation and Fibrinolysis is an international fully refereed journal that features review and original research articles on all clinical, laboratory and experimental aspects of haemostasis and thrombosis. The journal is devoted to publishing significant developments worldwide in the field of blood coagulation, fibrinolysis, thrombosis, platelets and the kininogen-kinin system, as well as dealing with those aspects of blood rheology relevant to haemostasis and the effects of drugs on haemostatic components. The journal publishes mutation reports detailing the mutated gene and giving a brief clinical history of the propositus. The journal also publishes correspondence, technical reports, mutation reports and reviews of books, software and new products. The emphasis is on speed of publication. The journal will normally publish within ten weeks of acceptance of manuscripts.

Points to consider before submission

We have prepared a standard covering letter (available from the journal website) to accompany your submission. Whether you use this letter or your own wording, please think carefully about the following points and make the appropriate declarations.

Redundant or duplicate publication
We ask you to confirm that your paper has not been published in its current form or a substantially similar form (in print or electronically, including on a web site), that it has not been accepted for publication elsewhere, and that it is not under consideration by another publication. The International Committee of Medical Journal Editors has provided details of what is and what is not duplicate or redundant publication (http://www.icmje.org). If you are in doubt (particularly in the case of material that you have posted on a web site), we ask you to proceed with your submission but to include a copy of the relevant previously published work or work under consideration by other journals. In your covering letter to the editors, draw attention to any published work that concerns the same patients or subjects as the present paper.

Conflicts of interest
We ask authors to state all possible conflicts of interest, including financial and other relationships. If you are sure that there is no conflict of interest, please state this. You might like to look at an editorial in the British Medical Journal on Beyond conflict of interest (http://bmj.com/cgi/content/short/317/7154/291). Remember that sources of funding should be acknowledged in your paper.

Permissions to reproduce previously published material
Authors should include with their submission copies of written permission to reproduce material published elsewhere (such as illustrations) from the copyright holder. Authors are responsible for paying any fees to reproduce material.

Patient consent forms
Patients have a right to privacy that should not be infringed without informed consent. Identifying details (written or photographic) should be omitted if they are not essential, but patient data should never be altered or falsified in an attempt to attain anonymity. Complete anonymity is difficult to achieve, and a consent form should be obtained if there is any doubt. For example, masking the eye region in photographs of patients is inadequate protection of anonymity. When informed consent has been obtained it should be indicated in the published article.

Ethics committee approval
All authors must sign a declaration that the research was conducted within the guidelines below and under the terms of all relevant local legislation. (Such a statement is included in the model submission letter on the journal’s web site.) The Editors reserve the right to judge the appropriateness of the use and treatment of humans or animals in experiments for publication in the journal.

Human experiments: All work must be conducted in accordance with the Declaration of Helsinki (http://www.wma.net/e/policy/b3.htm). Papers describing experimental work on human participants which carries a risk of harm must include (1) a statement that the experiments were conducted with the understanding and the consent of each participant, and (2) a statement that the responsible ethical committee has approved the experiments.

Animal experiments: In papers describing experiments on living animals, include (1) a full description of any anaesthetic and surgical procedure used, and (2) evidence that all possible steps were taken to avoid animals’ suffering at each stage of the experiment. In experiments involving the use of muscle relaxants, describe the precautions taken to ensure adequate anaesthesia (J Physiol 1990; 420:xii–xiii).

Experiments on isolated tissues: Indicate precisely how you obtained the donor tissue. The NIH guide for the care and use of laboratory animals (National Institutes of Health Publications No. 80-23, revised 1978) gives guidelines for the acquisition and care of animals.

Authorship
All authors must sign the letter accompanying their submission to confirm that they have read and approved the paper, that they have met the criteria for authorship as established by the International Committee of Medical Journal Editors, that they believe that the paper represents honest work, and that they are able to verify the validity of the results reported. You might also be interested to read the debate on authorship in general in the British Medical Journal’s Authorship collection (http://bmj.com/cgi/collection/authorship). Many of the points covered above are discussed in the New England Journal of Medicine’s collection of papers entitled ’Editorials on Journal Policy’ (http://authors.nejm.org/Misc/Policies.asp).

Compliance with NIH and Other Research Funding Agency Accessibility Requirements
A number of research funding agencies now require or request authors to submit the post-print (the article after peer review and acceptance but not the final published article) to a repository that is accessible online by all without charge. As a service to our authors, LWW will identify to the National Library of Medicine (NLM) articles that require deposit and will transmit the post-print of an article based on research funded in whole or in part by the National Institutes of Health, Wellcome Trust, Howard Hughes Medical Institute, or other funding agencies to PubMed Central. The revised Copyright Transfer Agreement provides the mechanism.

Copyright assignment
Papers are accepted for publication on the understanding that exclusive copyright in the paper is assigned to the Publisher. Authors are asked to sign a copyright assignment form after acceptance of their papers. They may use material from their paper in other works published by them.

Submissions

Authors are strongly encouraged to submit their manuscripts through the web-based tracking system at http://www.editorialmanager.com/bcf/. Signed author forms may be included in the submission as a 'supporting document' or mailed to the journal office. The site contains instructions and advice on how to use the system. Authors should NOT in addition then post a hard copy submission to the editorial office, unless you are supplying artwork, letters or files that cannot be submitted electronically, or have been instructed to do so by the editorial office. Include the following where appropriate: subject consent forms; transfer of copyright form; permission to reproduce previously published material; checklist. For those authors who have no option but to submit by mail please send one copy of the article, plus an electronic version on disk or CD-ROM, to either editor dependent on your geographical location. Authors from Europe, Asia (apart from Japan), Africa and Australia should submit to: Evgueni Saenko, Ph.D.,University of Maryland, School of Medicine Center for Vascular and Inflammatory Diseases Department of Biochemistry and Molecular Biology 800 W.

Presentation of papers

Title Page
The Title Page should carry the full title of the paper and a short title, of no more than 45 characters and spaces, to be used as a ‘running head’ (and which should be so identified). The first name, middle initial and last name of each author should appear. If the work is to be attributed to a department or institution, its full name should be included. Any disclaimers should appear on the Title Page, as should the name and address of the author responsible for correspondence concerning the manuscript and the name and address of the author to whom requests for reprints should be made. Finally, the Title Page should include the sources of any support for the work in the form of grants, equipment, drugs, or any combination of these. Disclose funding received for this work from any of the following organizations: National Institutes of Health (NIH); Wellcome Trust; Howard Hughes Medical Institute (HHMI); and other(s).

Abstracts
The second page should carry a structured abstract of no more than 250 words. The abstract should state the Objective(s) of the study or investigation, basic Methods (selection of study subjects or laboratory animals; observational and analytical methods), main Results (giving specific data and their statistical significance, if possible), and the principal Conclusions. It should emphasise new and important aspects of the study or observations.

Key Words
The abstract should be followed by a list of 3 - 10 keywords or short phrases which will assist the cross-indexing of the article and which may be published. When possible, the terms used should be from the Medical Subject Headings list of the Index Medicus (http://www.nlm.nih.gov/mesh/meshhome.html).

Text
Full papers of an experimental or observational nature may be divided into sections headed Introduction, Methods (including ethical and statistical information), Results and Discussion (including a conclusion), although reviews may require a different format.

Acknowledgements

Acknowledgements should be made only to those who have made a substantial contribution to the study. Authors are responsible for obtaining written permission from people acknowledged by name in case readers infer their endorsement of data and conclusions.

References
References should be numbered consecutively in the order in which they first appear in the text. They should be assigned Arabic numerals, which should be given in brackets, e.g. [17]. References should include the names of all authors when six or fewer; when seven or more, list only the first six names and add et al. References should also include full title and source information. Journal names should be abbreviated as in the Index Medicus (http://www.nlm.nih.gov/tsd/serials/terms_cond.html).

Unpublished work accepted for publication but not yet released should be included in the reference list with the words ‘in press’ in parentheses beside the name of the journal concerned. References must be verified by the author(s) against the original documents.

Tables
Each table should be typed on a separate sheet in double spacing. Tables should not be submitted as photographs. Each table should be assigned an Arabic numeral, e.g. (Table 3) and a brief title. Vertical rules should not be used. Place explanatory matter in footnotes, not in the heading. Explain in footnotes all non-standard abbreviations that are used in each table. Identify statistical measures of variations, such as standard deviation and standard error of the mean.

Be sure that each table is cited in the text. If you use data from another published or unpublished source, obtain permission and acknowledge the source fully.

Illustrations
References to figures and tables should be made in order of appearance in the text and should be in Arabic numerals in parentheses, e.g. (Fig. 2). Most file formats are accepted, but TIFF and EPS files, with fonts embedded, are preferred. If scanned, line art should be at a resolution of 800 dpi, and halftones and colour at 300 dpi. All colour values should be CMYK. If hard copies are submitted they should have a label pasted to the back bearing the figure number, the title of the paper, the author’s name and a mark indicating the top of the figure. Illustrations should be presented to a width of 82 mm or, when the illustration demands it, to a width of 166 mm. Photomicrographs must have internal scale markers. If photographs of people are used, their identities must be obscured or the picture must be accompanied by written consent to use the photograph. If a figure has been published before, the original source must be acknowledged and written permission from the copyright holder for both print and electronic formats should be submitted with the material. Permission is required regardless of authorship or publisher, except for documents in the public domain. Figures may be reduced, cropped or deleted at the discretion of the editor. Colour illustrations are acceptable but authors will be expected to cover the extra reproduction costs (for current charges, contact the publisher).

Legends for illustrations
Captions should be typed in double spacing, beginning on a separate sheet of paper. Each one should have an Arabic numeral corresponding to the illustration to which it refers. Internal scales should be explained and staining methods for photomicrographs should be identified.

Units of measurement
Measurements of length, height, weight, and volume should be reported in metric units (metre, kilogram, or litre) or their decimal multiples. Temperatures should be given in degrees Celsius. Blood pressures should be given in millimetres of mercury.

All haematologic and clinical chemistry measurements should be reported in the metric system in terms of the International System of Units (SI). Editors may request that alternative or non-SI units be added by the authors before publication.

Abbreviations and symbols
Use only standard abbreviations. Avoid abbreviations in the title and abstract. The full term for which an abbreviation stands should precede its first use in the text unless it is a standard unit of measurement.

Offprints

Offprints may be purchased using the appropriate form that will be made available with proofs. Orders should be sent when the proofs are returned; orders received after this time cannot be fulfilled.
