      Personal communications or manuscripts either “in preparation” or “submitted for publication” are unacceptable as reference.

    If you provide any photographs of patients, either they should not be identifiable or the photographs should be accompanied by written
    permission to use them.

    • Number all figures in the order of their citation in the text.
    • Include a title for each figure (no longer than 15 words).
    • Figures should be embedded in the main manuscript file immediately following the references.
    • Multi-panel figures (for example Fig. 1a, 1b, 1c, 1d) should be submitted as a single composite file that contains all parts of the figure.
    • Letters, numbers and symbols should be clear and the same throughout, and should contrast with the background.
    • Figure titles and legends should be provided in the main manuscript, not in the graphic file.
    • NAJMS encourages authors to publish color figures.

    Figure Legends
    The legends should be included in the main manuscript text file immediately following the figures. For each figure, the following information should be provided:

    • All figures must have Arabic numbers corresponding to the illustrations (i.e., Fig. 1, 2, 3 etc.).
    • Short title of figure (maximum 15 words).
    • Supply a detailed explanation of each figure (maximum length, 40 words).
    • Define all symbols and arrows that are used to identify parts of the figures.
    • Explain internal scale and identify the method of staining in photomicrographs.

    Please note: it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures that have previously been published elsewhere.


    • Include a title for each table (no longer than 15 words) in a single file.
    • Table should be numbered consecutively with Arabic numerals in order of appearance in the text.
    • Submit tables in a word processing—not an imaging—format.
    • Explain all nonstandard abbreviations in footnotes.
    • Identify statistical measures of variations, such as SD or SE. Do not merely repeat information in the text.
    • Supply written permissions to use data from another published or unpublished source.

    Please note: it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce tables that have previously been published elsewhere.

    Creating a Table
    Use the table editor of the word processing software to build a table. Each piece of data needs to be contained in its own cell in the table. Tables should be single-spaced. Avoid creating tables using spaces or tabs. Do not try to align cells with hard returns or extra spaces. Similarly, no cell should contain a hard return or tab. Although individual empty cells are acceptable in a table, be sure there are no empty columns. All P values should be reported as exact numbers to 2 digits past the decimal point, regardless of significance, unless they are lower than 0.01, in which case they should be presented to 3 digits. Express any P values lower than 0.001 as P<.001. P values can never equal 0 or 1.

    Units of Measurement
    Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples. Temperatures should be given in degrees Celsius. Blood pressures should be given in millimeters of mercury. All hematologic 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.

    Patient Anonymity and Informed Consent
    It is the author's responsibility to ensure that a patient’s anonymity be 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. Authors should mask patients' eyes and remove patients' names from figures unless they obtain written consent from the patients and submit written consent with the manuscript.

    Authors must submit written permission from the
    copyright owner (usually the publisher) to use direct quotations, tables, or illustrations that have appeared in copyrighted form elsewhere, along with complete details about the source. Any permission fees that might be required by the copyright owner are the responsibility of the authors requesting use of the borrowed material. For permission links, please visit the Links for Permissions.

    Accepted Manuscripts
    The designated corresponding author will receive notification of availability of page proofs by e-mail. It is the author's responsibility to ensure that there are no errors in the proofs. Proofs must be checked carefully and corrections sent back within 48 hours of receipt, as requested in the electronic cover letter accompanying the page proofs.

    Page Charges
    The journal does not currently require any page charges, color charges or article processing charges.

    Open Access
    All articles published in the journal are "open access". This indicate that articles published online can be freely accessed at the journal's website by all users. The journal automatically provides open access to the published articles, therefore, does not provide an offprint, while publications are online.

    Authorship Criteria and Authorship
    Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. One or more authors should take responsibility for the integrity of the work as a whole, from inception to published article. Authorship credit should be based on a) substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data; b) drafting the article or revising it critically for important intellectual content; and c) final approval of the version to be published.

    For reports of original data and systematic reviews, authors’ specific contributions will be published in the Acknowledgment section. All other persons who have made substantial contributions to the work reported in this manuscript but who do not fulfill the authorship criteria should be named with their specific contributions in the Acknowledgment section in the manuscript.

    The authors must also certify that the manuscript represents valid work and that neither this manuscript nor one with substantially similar content under their authorship has been published or is being considered for publication elsewhere.

    Role of the Corresponding Author
    The corresponding author will act on behalf of all coauthors as the primary correspondent with the editorial office during the submission and review process. If the manuscript is accepted, the corresponding author will review an edited typescript and proof, make decisions regarding release of information in the manuscript to the news media, federal agencies, or both, and will be identified as the corresponding author in the published article. The corresponding author is responsible for ensuring that the Acknowledgment section of the manuscript is complete.

    Peer Review and Processing
    The peer review is to ensure that good science is published. All submitted manuscripts are reviewed initially by a NAJMS editor. Manuscripts with insufficient priority for publication are rejected promptly, without detailed review. Manuscripts with sufficient priority for publication will be reviewed by at least two experts. Peer reviewer identities are kept confidential, but author identities are made known to reviewers. The existence of a manuscript under review is not revealed to anyone other than peer reviewers and editorial staff.

    The peer review process of NAJMS not only judges the importance of the work, but also focuses on whether the work is done to high scientific and ethical standards, is appropriately described, and that the data supports the conclusions. The final decision is made on the basis that the peer reviewers are in accordance with one another, or that at least there is no strong dissenting view. In cases where there is strong disagreement, either among peer reviewers or between the authors and peer reviewers, advice is sought from a member of the journal's
    Editorial Board. Our Editorial Board, therefore, plays a vital role in maintaining the high standards of NAJMS while ensuring that it retains the speed of publication necessary for a rapid communication journal. The ultimate responsibility for editorial decisions lies with the Editor-in-Chief.

    Once an article is accepted, it is assigned with
    Digital Object Identifier (DOI) names, and is published in NAJMS immediately as a provisional PDF file. The article will subsequently be published both in fully browseable web form and as a formatted PDF. Information about a digital object may change over time, including where to find it, but its DOI name will not change.
