Categories of Articles

Original Articles. Original articles are concise (1) reports of clinical data, (2) reports of basic science data, or (3) reviews, including meta-analyses, that represent advanced information and a new contribution to literature as determined by the IJMV editorial staff. Original Articles require structured abstracts as detailed under “Abstract.” Text should not exceed 12 double-spaced pages, 25 references, and a maximum of 6 to 8 figures/tables.

Clinical Notes/Case Reports. A case report1 should be concise and focused on one topic that results in final publication of not more than 2 journal pages, including references. As best as possible, the title should state the compelling point that draws the reader’s attention. In lieu of a structured abstract, the first 150 words will explicitly identify the compelling point of the report. Case reports may also be based on seminal. Text should not exceed 6 double-spaced pages, 15 references, and a maximum of 4 figures/tables.

Clinical Challenges. The Editors welcome suggestions of topics for the series. The author’s charge is to present a fair and balanced reflection of the good-quality information in the recent medical literature. The format is (1) Hypothesis: the controversial or puzzling statement; (2) Pro: a summary of current knowledge supporting this statement; (3) Con: a summary of current knowledge refuting this statement; (4) Bottom Line: your opinion of the truth or fallacy (or partial truth/fallacy) of the original hypothetical statement; and (5) References: the most relevant only, 10 or fewer. Also, list the key words used in your search so others can duplicate it if they wish. This review should be concise. Text should not exceed 8 to 10 double-spaced pages. The author should enclose a self-photograph to be published along with the article. When this review is published, it will appear along with a short clinical commentary generally regarded as experts in this area. While the review is intended as straightforward information, these commentaries will reflect the personal experience of the clinicians.

Reflections. This section features an essay of 1 journal page designed to relate those personal experiences that have no scientific or statistical basis. All submissions to Reflections must be previously unpublished. Any references to individuals mentioned by name must be accompanied by a signed release from the individual or from the individual’s family, if the person is deceased. Text should not exceed 3 double-spaced pages.

Letters to the Editor. Letters discussing a recent IJMV article should not exceed 400 words of text and 5 references. Research Letters reporting original research, including case series or case reports, also are welcome and should not exceed 600 words of text and 6 references.

Cover Photographs. Submissions must be formatted horizontally. They can be black and white or color and at least 3.5 × 5 inches but no larger than 8 × 10 inches. Due to legal concerns, no recognizable people should appear in the picture. Please include details about where the picture was taken, how you happened to be there, and anything else you think is interesting about the image. We need the photographer’s complete name, highest academic degree, city and state of residence, and a statement explaining how the photographer is affiliated with the journal. If you would like your photo returned, please enclose a self-addressed, stamped envelope. Cover photos will be chosen at the discretion of the IJMV editorial staff.

 

Editorial Policies for Authors

Authorship Criteria and Contributions. Designate a corresponding author and provide a complete address, telephone number, fax number, and e-mail address. Authors are required to identify their contributions to the work described in the manuscript. Please mail or fax the authorship form with statements on (1) authorship responsibility, criteria, and contributions, (2) data access and responsibility (if the manuscript contains original data, this statement must be signed by at least 1 author who is independent of any commercial funder, eg, the principal investigator; for industry-sponsored studies, the data analysis should be conducted by statisticians in an academic center, rather than only by statisticians employed by the company sponsoring the research), (3) financial disclosure, and either copyright transfer or federal employment. (4) The corresponding author must sign the acknowledgment statement.2

Acknowledgments. Authors are responsible for obtaining written permission from all persons named in an acknowledgment, if applicable.3 The corresponding author must sign the acknowledgment statement of the required form.

Group Authorship. If authorship is attributed to a group (either solely or in addition to 1 or more individual authors), all members of the group must meet the full criteria and requirements for authorship described in these Instructions. A group must designate at least 1 or more individuals as authors or members of a writing group who meet full authorship criteria and requirements and who will take responsibility for the group, in which case the other group members are not authors, but may be listed in an acknowledgment.4

Conflict of Interest. A conflict of interest may exist when an author (or the author’s institution or employer) has financial or personal relationships that could inappropriately influence (or bias) the author’s decisions, work, or manuscript. All authors are required to report potential conflicts of interest, including specific financial interests relevant to the subject of their manuscript, in their cover letter and on the financial disclosure form or in an attachment to the form. Authors without relevant financial interests in the manuscript should indicate no such interest.

Authors are required to report detailed information regarding all financial and material support for the research and work, including but not limited to grant support, funding sources, and provision of equipment and supplies. Each author is also required to sign and submit the following financial disclosure statement: “I certify that all my affiliations with or financial involvement, within the past 5 years and foreseeable future (eg, employment, consultancies, honoraria, speakers bureau, stock ownership or options, expert testimony, grants received or pending, patents filed, received, pending, or in preparation, royalties, donation of medical equipment) with any organization or entity with a financial interest in or financial conflict with the subject matter or materials discussed in the manuscript are completely disclosed.”

Authors are expected to provide detailed information about any relevant financial interests or financial conflicts within the past 5 years and for the foreseeable future, particularly those present at the time the research was conducted and up to the time of publication, as well as other financial interests, such as relevant patents filed, received, pending, or in preparation, that represent potential future financial gain. Although many universities and other institutions and organizations have established policies and thresholds for reporting financial interests and other conflicts of interest, IJMV requires complete disclosure of all relevant financial relationships and potential financial conflicts of interest, regardless of amount or value. If authors are uncertain about what might constitute a potential financial conflict of interest, they should err on the side of full disclosure and should contact the editorial office if they have questions or concerns. In addition, authors who have no relevant financial interests are now asked to provide a statement indicating that they have no financial interests related to the material in the manuscript.

This information is for the editorial office and is not shared with peer reviewers. However, for all accepted manuscripts, authors’ disclosure of relevant financial interests and declarations of no relevant financial interests will be published. Decisions about whether financial information provided by authors should be published, and thereby disclosed to readers, are usually straightforward. Although editors are willing to discuss disclosure of specific financial information with authors, the IJMV’s policy is one of complete disclosure of all relevant financial interests.

This policy applies to all manuscript submissions, including letters to the editor.

Funding/Support and Role of Sponsor. All financial and material support for the research and the work should be clearly and completely identified in an acknowledgment. The role of the funding organization or sponsor in each of the following should be specified: design and conduct of the study; collection, management, analysis, and interpretation of the data; and preparation, review, or approval of the manuscript.

Data Access and Responsibility. For reports containing original data, at least 1 author who is independent of any commercial funder (eg, the principal investigator) should indicate that he or she had full access to all the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis.5 For industry-sponsored studies, the data analysis should be conducted by statisticians in an academic center, rather than only by statisticians employed by the company sponsoring the research.

Prior Publication or Duplicate Submission. Manuscripts are considered with the understanding that they have not been published previously in print or electronic format and are not under consideration by another publication or electronic medium.

Reporting Race/Ethnicity. If race or ethnicity is reported, indicate who classified the individuals as to race/ethnicity and whether the options were defined by the investigator or by the participant. Explain why race or ethnicity was assessed in the study.6

Informed Consent. For experimental investigations of human subjects, state in the “Methods” section of the manuscript that the appropriate institutional review board approved the project. For those investigators who do not have formal ethics review committees (institutional or regional), the principles outlined in the Declaration of Helsinki should be followed.7 Specify in the “Methods” section the manner in which consent was obtained from all human subjects.

Case Descriptions and Photographs. Include a signed statement of consent to publish (in print and online) all case descriptions and photographs from all patients (parents or legal guardians for minors) who can be identified in such written descriptions, photographs, or pedigrees. Please do not send masked photographs of patients.

Animal Experimentation. For experimental investigations of animal subjects, specify in the “Methods” section of the manuscript what animal-handling protocols were followed, eg, “Institutional guidelines regarding animal experimentation were followed.” For those investigators who do not have formal ethics review committees (institutional or regional), the principles outlined in the Declaration of Helsinki should be followed.7

Unauthorized Use. Accepted manuscripts become the permanent property of the IJMV and may not be published elsewhere without written permission from the IJMV.

 

Editorial Review and Publication

Editorial Peer Review. Reviews and decisions on manuscripts in which the editor or one of the associate editors is a coauthor are managed independently by an associate editor from another institution, in conjunction with a member of the editorial board.

Editing. Accepted manuscripts are copyedited according to AMA style and returned to the author for approval. Authors are responsible for all statements made in their work, including changes made by the manuscript editor and authorized by the corresponding author.

Manuscript Preparation

Manuscripts should be prepared in accordance with the AMA Manual of Style8 and/or the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals.”9

  • • Manuscripts submitted via the online system should not also be submitted by mail.
  • • If a submission is accepted for publication, we will require slides or high-quality glossies of all figures (computer-generated graphics produced by high-quality laser printers are acceptable for black-and-white line art only).
  • • Use only 10- or 12-point font size.
  • • Double-space throughout using 1-inch margins, including title page, abstract, text, acknowledgments, references, figure legends, and tables. Do not use line numbering.
  • • Titles should not exceed 75 characters, including punctuation and spacing. Avoid abbreviations in the title, abstract, and text.

Title Page (page 1 of manuscript). Give full names, highest academic degrees, and institutional affiliations of all authors. (If an author’s affiliation has changed since the work was done, list the new affiliation as well.) Designate a corresponding author and include a complete mailing address, telephone number, fax number, and e-mail address. Specify the address to which requests for reprints should be sent. If the manuscript was presented at a meeting, please specify the name of the meeting, the city where it was held, and the exact date on which the paper was read or the poster was presented. Also include on the title page a word count for the text only, exclusive of the title, abstract, references, tables, and figure legends.

Abstract (page 2 of manuscript). Include a structured abstract of no more than 250 words for reports of original data from clinical or basic science investigations and reviews (including meta-analyses).10

Units of Measure. Laboratory values are expressed using conventional units of measure, with relevant Système International (SI) conversion factors expressed secondarily (in parentheses) only at first mention. Articles that contain numerous conversion factors may list them together in a paragraph at the end of the “Methods” section. In tables and figures, a conversion factor to SI units should be provided in a footnote or legend. The metric system is preferred for the expression of length, area, mass, and volume. A Conversion Table is available on the Web site for the AMA Manual of Style.

Drug Names. Use generic names of drugs, unless the specific trade name of a drug used is directly relevant to the discussion.

Reproduced Materials. Reprinted tables and figures are discouraged. Original material should be provided, except under extraordinary circumstances. Acknowledge all illustrations and tables reprinted from other publications and submit written permission to reproduce (in print and online and in all licensed versions) from the original publishers.

References. Number references in the order they are mentioned in the text; do not alphabetize. In text, tables, and legends, identify references with superscript arabic numerals. In listing references, follow AMA style, abbreviating names of journals according to Index Medicus. List all authors and/or editors up to 6; if more than 6, list the first 3 and “et al.” The reference numbers in the reference list should be keystroked. Please do not use a word processing program to generate the reference numbers, using such features as automatic footnotes or endnotes.

Web References. Please keep a print copy of any reference to Web-only information. If the URL changes or disappears, interested readers may contact the corresponding author for a copy of the information.

Authors are responsible for the accuracy and completeness of their references and for correct text citation.

Tables. Title all tables and number them in order of their citation in text. If a table must be continued, repeat the title on a second sheet, followed by (“cont”). Make certain each item in the table is in its own table cell. Do not use paragraph returns (to start new rows) or tabs (to start new columns) to format the table.

Figures. Each figure must be submitted in a separate file. Figures should be submitted as high-resolution TIF or JPG files. Submit your photographic images at 5 inches (13 cm) wide at 300 pixels per inch (120 pixels per centimeter), minimum. This applies to each part for multipart figures. Save them as TIF (with LZW compression), JPG (with “maximum quality” setting), or PSD (native Adobe Photoshop format). Please do not add arrowheads, “a,” “b,” asterisks, etc directly to the file that contains the single figure. A separate composite figure in PowerPoint may be submitted to show the location of arrows, asterisks, etc.

Digitally enhanced images (eg, computed tomographic-magnetic resonance imaging scans, blots, photographs, photomicrographs, ultrasound images, x-ray films) must be clearly identified in the figure legends as electronically enhanced or manipulated. If your manuscript is accepted, you will be asked to provide 3 clearly labeled copies of the enhanced images and 3 copies of the original images.

Digital Art Submissions. RGB color submissions are preferred. Calibrated color proofs should be submitted with color digital files, if possible. The canvas size of continuous tone images should be at least 5 inches wide (depth not important) with an image resolution of at least 350 ppi. Line art images should have a minimum resolution of at least 1270 ppi. Formats acceptable are EPS, TIF, and JPG.

Image Integrity. Preparation of scientific images (clinical images, radiographic images, micrographs, gels, etc) for publication must preserve the integrity of the image data. Digital adjustments of brightness, contrast, or color applied uniformly to an entire image are permissible as long as these adjustments do not selectively highlight, misrepresent, obscure, or eliminate specific elements in the original figure, including the background. Selective adjustments applied to individual elements in an image are not permissible. Individual elements may not be moved within an image field, deleted, or inserted from another image. Cropping may be used for efficient image display but must not misrepresent or alter interpretation of the image by selectively eliminating relevant visual information. Juxtaposition of elements from different parts of a single image or from different images, as in a composite, must be clearly indicated by the addition of dividing lines, borders, and/or panel labels.

When inappropriate image adjustments are detected by the IJMV staff, authors will be asked for an explanation and will be requested to submit the image as originally captured prior to any adjustment, cropping, or labeling. Authors may be asked to resubmit the image prepared in accordance with the above standards. Deliberate alteration of images that results in misrepresentation of data may be reported to the author’s institution or funding agency.

Legends. Legends (maximum 40 words) should be typed double-spaced, on a separate page from the text. Indicate magnification and stains used for photomicrographs. Include specific postoperative intervals where applicable.

Videos. For editorial and peer review of an initial submission, submit videos in .mov, .wmv, .mpg, .mpeg, .mp4, or .avi file format. To facilitate uploading and reviewing, the initial video submitted should not exceed 10 MB. Verify that all videos are viewable in QuickTime or Windows Media Player before submission. Once the video has been approved for submission, you will be asked to upload an uncompressed version of the file in .dv or similar format (no size limit), with minimum physical dimensions of 480 pixels wide by 360 pixels high, to a secure FTP server. Please be prepared to provide this larger version promptly on request.

If the author does not hold copyright to the video, the author must obtain permission for the video to be published in IJMV. This permission must be for unrestricted use in all print, online, and licensed versions of the journal. Submit the completed form to the editorial office.

General guidelines for videography:

  • • White-balance the camera.
  • • Use plenty of diffuse light; avoid shadows.
  • • Avoid incandescent (yellow) light. Use fluorescent lighting if possible. Use the appropriate setting/filter on the camera and always white-balance.
  • • Do not overexpose the image; a bit underexposed is preferable.
  • • Use a tripod. This is especially important in close-ups.
  • • Avoid excessive zooming. Use the optical zoom only; do not use a digital zoom.
  • • Turn all camera special effects off.
  • • Avoid using auto-focus. Manual focus is more accurate. Keep the camera at a fixed distance from the subject.
  • • Do not include an introduction by the physician as a “talking head” explaining a procedure. All footage should be of the procedure or relevant subject matter only.
  • • Provide a pause after changing the camera’s position. This allows for easier editing.
  • • When filming procedures, keep the physician’s head, hands, and any instruments away from the sightline of the camera. Instruct all involved surgical staff what is going to happen. Instruct assistants to minimize reaching across the field and suction tip entry in and out of the field, and to avoid having soiled surgical sponges obscure the view of the field. You may wish to practice access into and out of the surgical field without intruding on the sightline of the camera prior to actually performing the procedure or doing the filming.
  • • For surgical procedures, white gloves reflect the light. If possible, use brown or tan gloves. Please do not use vividly colored surgical gloves as they distract the viewer from the teaching point of the video.
  • • Be slow and deliberate in your movements. If you need to demonstrate a special instrument, hold it steady in one place to allow the camera to focus on it prior to your use of the instrument.

For each video, provide a citation in the appropriate place in the manuscript text and include a title (a brief phrase, preferably no longer than 10-15 words) and a caption/legend (a brief description or summary of the content) at the end of the manuscript. In the video caption/legend, specify the video file format and briefly describe the content of the video. Also, enter the same title and caption/legend in the designated fields on the Web-based manuscript submission system when uploading each video. If multiple video files are submitted, number them in the order in which they should be viewed.

Note: If the manuscript and accompanying video(s) are accepted for publication, all video files will be placed into a journal video frame and may be edited by the journal staff according to journal style.

 

Instructions for Preparing Structured Abstracts*

All manuscripts that are (1) reports of clinical data, (2) reports of basic science data, or (3) reviews, including meta-analyses, should be submitted with structured abstracts as described below.

To permit quick and selective scanning and allow more information to be conveyed per unit of space, the headings outlined below should be included in the abstract. For brevity, parts of the abstract can be written in phrases rather than complete sentences. (For example: “2. Design. Double-blind randomized trial,” rather than “2. Design. The study was conducted as a double-blind, randomized trial.”)

*Adapted from Haynes RB, Mulrow CD, Huth EJ, Altman DG, Gardner MJ. More informative abstracts revisited. Ann Intern Med. 1990;113(1):69-76.

 

Reports of Clinical Data

Authors submitting manuscripts reporting clinical data should prepare an abstract of no more than 250 words under the following headings: Objective, Design, Setting, Patients (or Other Participants), Interventions (if any), Main Outcome Measures, Results, and Conclusions. The content following each heading should be as follows:

  • 1. Objective. The abstract should begin with a clear statement of the precise objective or question addressed in the report. If more than 1 objective is addressed, the main objective should be indicated and only key secondary objectives stated. If an a priori hypothesis was tested, it should be stated.
  • 2. Design. The basic design of the study should be described. The duration of follow-up, if any, should be stated. As many of the following terms as apply should be used.
    • A. Intervention studies: randomized controlled trial; nonrandomized controlled trial; double-blind; placebo-controlled; crossover trial; before-after trial.
    • B. For studies of screening and diagnostic tests: criterion standard (that is, a widely accepted standard with which a new or alternative test is being compared; this term is preferred to “gold standard”); blinded or masked comparison.
    • C. For studies of prognosis: inception cohort (subjects assembled at a similar and early time in the course of the disorder and followed thereafter); cohort (subjects followed forward in time, but not necessarily from a common starting point); validation cohort or validation sample if the study involves the modeling of clinical predictions.
    • D. For studies of causation: randomized controlled trial; cohort; case-control; survey (preferred to “cross-sectional study”).
    • E. For descriptions of the clinical features of medical disorders: survey; case series.
    • F. For studies that include a formal economic evaluation: cost-effectiveness analysis; cost-utility analysis; cost-benefit analysis. For new analyses of existing data sets, the data set should be named and the basic study design disclosed.
  • 3. Setting. To assist readers to determine the applicability of the report to their own clinical circumstances, the study setting(s) should be described. Of particular importance is whether the setting is the general community, a primary care or referral center, private or institutional practice, ambulatory or hospitalized care.
  • 4. Patients or Other Participants. The clinical disorders, important eligibility criteria, and key sociodemographic features of patients should be stated. The numbers of participants and how they were selected should be provided (see below), including the number of otherwise eligible subjects who were approached but refused. If matching is used for comparison groups, characteristics that are matched should be specified. In follow-up studies, the proportion of participants who completed the study must be indicated. In intervention studies, the number of patients withdrawn for adverse effects should be given. For selection procedures, these terms should be used, if appropriate: random sample (where “random” refers to a formal, randomized selection in which all eligible subjects have a fixed and usually equal chance of selection); population-based sample; referred sample; consecutive sample; volunteer sample; convenience sample. These terms assist the reader to determine an important element of the generalizability of the study. They also supplement (rather than duplicate) the terms used by professional indexers when articles are entered into computerized databases.
  • 5. Intervention(s). The essential features of any interventions should be described, including their method and duration of administration. Common synonyms should be given as well to facilitate electronic text word searching. This would include the brand name of a drug if a specific product was studied.
  • 6. Main Outcome Measure(s). The primary study outcome measurement(s) should be indicated as planned before data collection began. If the paper does not emphasize the main planned outcomes of a study, this fact should be stated and the reason indicated. If the hypothesis being reported was formulated during or after data collection, this information should be clearly stated.
  • 7. Results. The main results of the study should be given. Measurements that require explanation for the expected audience of the manuscript should be defined. Important measurements not included in the presentation of results should be declared. As relevant, it should be indicated whether observers were blinded to patient groupings, particularly for subjective measurements. Due to the current limitations of retrieval from electronic databases, results must be given in narrative or point form rather than tabular form if the abstract is to appear in computerized literature services such as MEDLINE. If possible, the results should be accompanied by confidence intervals (for example, 95%) and the exact level of statistical significance. For comparative studies, confidence intervals should relate to the differences between groups. For nonsignificant differences for the major study outcome measure(s), the clinically important difference sought should be stated and the confidence interval for the difference between the groups should be given. When risk changes or effect sizes are given, absolute values should be indicated so that the reader can determine the absolute as well as relative impact of the finding. Approaches such as “number needed to treat” to achieve a unit of benefit are encouraged when appropriate; reporting of relative differences alone is usually inappropriate. If appropriate, studies of screening and diagnostic tests should use the terms “sensitivity,” “specificity,” and “likelihood ratio.” If predictive values or accuracy is given, prevalence or pretest likelihood should be given as well. No data should be reported in the abstract that do not appear in the rest of the manuscript.
  • 8. Conclusions. Only those conclusions of the study that are directly supported by the evidence reported should be given, along with their clinical application (avoiding speculation and overgeneralization), and indicating whether additional study is required before the information should be used in usual clinical settings. Equal emphasis must be given to positive and negative findings of equal scientific merit.

Review Manuscripts (Including Meta-analyses)

Authors submitting review manuscripts and reports of the results of meta-analyses should prepare an abstract of no more than 250 words under the following headings: Objective, Data Sources, Study Selection, Data Extraction, Data Synthesis, and Conclusions. The content following each heading should be as follows:

  • 1. Objective. The abstract should begin with a precise statement of the primary objective of the review. The focus of this statement should be guided by whether the review emphasizes factors such as cause, diagnosis, prognosis, therapy, or prevention. It should include information about the specific population, intervention, exposure, and test or outcome that is being reviewed.
  • 2. Data Sources. A succinct summary of data sources should be given, including any time restrictions. Potential sources include experts or research institutions active in the field, computerized databases and published indexes, registries, abstract booklets, conference proceedings, references identified from bibliographies of pertinent articles and books, and companies or manufacturers of tests or agents being reviewed. If a bibliographic database is used, the exact indexing terms used for article retrieval should be stated, including any constraints (for example, English language or human subjects).
  • 3. Study Selection. The abstract should describe the criteria used to select studies for detailed review from among studies identified as relevant to the topic. Details of selection should include particular populations, interventions, outcomes, or methodologic designs. The method used to apply these criteria should be specified (for example, blind review, consensus, multiple reviewers). The proportion of initially identified studies that met selection criteria should be stated.
  • 4. Data Extraction. Guidelines used for abstracting data and assessing data quality and validity (such as criteria for causal inference) should be described. The method by which the guidelines were applied should be stated (for example, independent extraction by multiple observers).
  • 5. Data Synthesis. The main results of the review, whether qualitative or quantitative, should be stated. Methods used to obtain these results should be outlined. Meta-analyses should state the major outcomes that were pooled and include odds ratios or effect sizes and, if possible, sensitivity analyses. Numerical results should be accompanied by confidence intervals, if applicable, and exact levels of statistical significance. Evaluations of screening and diagnostic tests should address issues of sensitivity, specificity, likelihood ratios, receiver operating characteristic curves, and predictive values. Assessments of prognosis could include summarizations of survival characteristics and related variables. Major identified sources of variation between studies should be stated, including differences in treatment protocols, co-interventions, confounders, outcome measures, length of follow-up, and dropout rates.
  • 6. Conclusions. The conclusions and their applications should be clearly stated, limiting generalization to the domain of the review. The need for new studies may be suggested.
