Instructions for Authors
General information
- Turkish Journal of Internal Medicine (TJIM) is an international, double-blind peer-reviewed scientific journal that publishes manuscripts describing clinical research in medicine.
- Manuscripts must describe original data that has not been published previously nor submitted for publication elsewhere.
- Manuscripts that adhere to the TJIM submission guidelines and are deemed appropriate for the scope of the journal are sent to two reviewers who are specialists in the field.
- The members of the Editorial Board who discuss the suitability then consider the reviewers’ comments on each submission.
- The final decision for all submitted manuscripts rests with the Editor-in-Chief.
Institutional review board/ethics committee approval (IRB)
If a study involves either human subjects, human-derived materials, and/or medical records, authors must include in the Methods section either a statement that an Institutional Review Board (IRB)/Ethics Committee approval has been obtained or a statement that the IRB/Ethics Committee had ruled that approval was not required for the study. When reporting experiments conducted with humans indicate that the procedures were in accordance with ethical standards set forth by the committee that oversees human experimentation. Approval of research protocols by the relevant ethics committee, in accordance with international agreements (Helsinki Declaration of 1975, revised 2002 available at http://www.wma.net/e/policy/b3.htm, “Guide for the Care and Use of Laboratory Animals” www.nap.edu/catalog/5140.html/), is required for all experimental, clinical, and drug studies. Patient names, initials, and hospital identification numbers should not be used. Manuscripts reporting the results of experimental investigations conducted with humans must state that the study protocol received institutional review board approval and that the participants provided informed consent.
Copyright transfer
The publisher retains the copyright to all material published in the TJIM. The publisher is not responsible for any legal claims arising from the publication of a manuscript. A Copyright Transfer Agreement form must be submitted together with the manuscript at the time of initial submission. All authors/corresponding authors must sign the form, indicating that all authors agree to the publication of their manuscript in the TJIM should their manuscript be accepted. A scanned file (PDF, TIFF, or JPEG) of the signed Copyright Transfer Agreement may be submitted at the time of online submission of the manuscript. The Editorial Office must receive the Copyright Transfer Agreement before any action can be taken regarding the manuscript.
Copyright of all publications is protected under a Creative Commons license (CC BY-NC-ND). This license allows reusers to copy and distribute the material in any medium or format in unadapted form only, for noncommercial purposes only, and only so long as attribution is given to the creator.
CC BY-NC-ND includes the following elements:
BY – Credit must be given to the creator
NC – Only noncommercial uses of the work are permitted
ND – No derivatives or adaptations of the work are permitted
Conflict of interest policy
Authors are required to disclose all conflicts of interest that may have influenced their research or the preparation and writing of their manuscript. Conflicts of interest may include both financial and non-financial relationships. Because it is often difficult to determine whether a conflict of interest exists, the Editorial Board requests that all potential conflicts be declared at the time of initial submission of the manuscript on the title page. Other pertinent relationships that may be relevant should be disclosed to the Editor-in-Chief in the cover letter at the time of submission.
Manuscript submission
All manuscripts must conform to the language and writing style of the TJIM. This includes submission of the manuscript with correct medical English as well as submission of any figures and tables in the formats specified. Authors should submit their manuscript and accompanying material to the TJIM via the online Editorial Manager system by logging on http://dergipark.org.tr/ and uploading all manuscript files following the instructions given.
Authorship
All authors should have been directly involved in the work described in the manuscript. Additional contributors to a manuscript, such as professors or others who gave helpful advice or companies that donated material, may be thanked in the Acknowledgments section following the main text. TJIM does not permit two or more authors to be “equal contributors” to a manuscript.
Permission
All figures, tables, and text passages that have been previously published require permission from the copyright owner(s) for the TJIM. All expenses related to obtaining such permission must be borne by the authors. By signing the copyright form, you state that TJIM owns the copyright to the material in your article. Permission must be obtained for any material to which the authors do not own the full copyright. No material such as clinical images or charts, photos, and graphs as well as images of devices that may have been obtained from their producers, can be published without such permission. To secure the right to publish material that you do not own, contact the holder of the copyright (journal in which it was published, book publishers, or company that developed the instrument) by e-mail describing in detail the material you wish to use and stating that you wish to include that material in your manuscript (including the title The copyright owner will usually reply stating that permission has been granted. A copy of the reply must be forwarded to the TJIM offices with the number of your manuscript and a description of the materials in question. Most copyright permissions will specify conditions relating to the way in which reference to the permission should be stated. These conditions must be adhered to in full, otherwise, the permission may be invalid. Note that in some instances copyright owners may require payment. In these cases, the authors must bear all such costs. As papers cannot be changed once accepted, authors are advised to apply for copyright permission early to prevent the possibility of the paper having to be withdrawn from publication. Note that receiving permission may take up to eight weeks and that the paper cannot be processed for publication before such permission has been granted.
Title page
The title page should present a title (and running title) that includes, if appropriate, the study design, and should list the full names and institutional addresses for all authors.
Types of Papers
All papers published by the Turkish Journal of Internal Medicine are peer-reviewed.
Original Article
An article is a full-length report on original primary research that will interest the journal's readers. They must describe significant and original observations.
Review Article
The review article is a comprehensive analysis of specific topics and recent developments in a particular area. A review should focus on recent research and issues. It should also include the authors' opinion on how to approach the topic/situation under discussion and what is needed to advance the field in the future.
Communications
Short (brief) communications are short papers that focus on a particular aspect of a problem or a new finding that is expected to have a significant impact and present original and important material. Short communication is not intended to publish preliminary results. They may be given rapid publication. Short communication should not be subdivided. The paper should include an abstract, main body of text (combined methods, results, and discussion in a single section), and references.
Rapid communications are similar to short communications. These are usually articles used to disseminate preliminary results that are original, of high interest, and likely to have a significant impact on the relevant scientific community. In the healthcare field, this can include information that is urgent from a public health perspective or findings in a rapidly changing specialty. Their format is similar to short communications.
Case Report
Case reports and case studies should present significant new insights or cases with an unusual and noteworthy course. It is recommended that case reports include an up-to-date review of all previous cases in the field. The novelty of the case(s) may lie in the phenotype, the presentation, the investigation, and/or the management.
Letter
Letters are encouraged if they directly concern articles recently published in the journal. If accepted, the editors reserve the right to submit such letters to the authors of the articles concerned prior to publication, in order to permit them to respond in the same issue of the journal.
Manuscript preparation
Manuscripts should be created using Microsoft Word and be double-spaced with 2.5-cm margins on all sides. Pages should be numbered consecutively, with consecutive line numbering from the first through the last page, using the automatic numbering function of the software. The recommended font is Times New Roman and the recommended font size is 11 points. The entire manuscript for a full-length article, excluding references and tables, should be no more than 6000 words. Do not use field functions. For indenting, use tab stops, not the space bar. For tables, use the table function, not spreadsheets. For equations, use either the equation editor or MathType.
Abstracts
A structured abstract of no more than 350 words is required. The Abstract for all manuscripts except case reports and review articles should be divided into Introduction, Methods, Results, and Conclusions.
Keywords
Keywords are required for indexing and abstracting services. Up to ten words should be listed.
Main text
The main text of an original article should be divided into INTRODUCTION, METHODS, RESULTS, DISCUSSION, and CONCLUSION sections. The case report should include an abstract, introduction, case report, discussion, and references. Abbreviations must be defined following their first use in the Abstract as well as in the main text and in the figures and tables. Only commonly accepted abbreviations should be used. Drug and chemical names should be stated using generic or standard chemical nomenclature. Units of measurement should conform to the International System (SI); however, clinical data may be presented in conventional units where deemed more appropriate.
Headings and subheadings
Main headings (INTRODUCTION, METHODS, RESULTS, DISCUSSION, etc.) and the word REFERENCES should be written in capital letters. In subheadings, only the first letter of each word should be capitalized.
Footnotes
Footnotes may be used to give additional information, but should not consist of a reference citation, which is not included in the reference list at the end of the manuscript, and must not contain figures or tables. Footnotes should be numbered consecutively and separately for the title page, the main text, and each table. Footnotes should be indicated by superscript lowercase letters or numbers, or by asterisks for significance values and other statistical data. Footnotes should be positioned at the bottom of the page or table in which they appear.
Tables, Graphics, and Illustrations
Tables, graphics, and illustrations should be numbered in Arabic numerals in the text. The places of the illustrations should be signed in the text.
Tables
- Tables capture information concisely and display it efficiently; they also provide information at any desired level of detail and precision. Including data in tables rather than text frequently makes it possible to reduce the length of the text.
- Tables must be numbered consecutively in the order in which they appear in the text (e.g., Table 1, Table 2, …). Table titles should be placed above the table in Times New Roman, 10-point font size. Table content should be written in Times New Roman, 10-point font size. If the table does not fit within the page, the font size may be reduced accordingly. Statistically significant values should be presented in bold. If the table has a source, it must be indicated below the table in Times New Roman, 9–10-point font size. Only the first letter of the first word in the table title should be capitalized. All other words should be lowercase (except for proper nouns).
- Authors should include explanatory information as notes below the table, not in the title.
- Be sure that each table is cited in the text. If you use data from another published or unpublished source, obtain permission and acknowledge that source fully.
- Additional tables containing backup data too extensive to publish in print may be appropriate for publication in the electronic version of the journal, deposited with an archival service, or made available to readers directly by the authors. An appropriate statement should be added to the text. Such tables should be submitted for consideration with the paper so that they will be available to the peer reviewers.
Illustrations (Figures)
- Figures should be either professionally drawn and photographed or submitted as digital prints in photographic quality. In addition to requiring a version of the figures suitable for printing, authors are asked for electronic files of figures in a format (for example, JPEG or GIF) that will produce high-quality images in the Web version of the journal; authors should review the images of such files on a computer screen before submitting them to be sure they meet their own quality standards.
- For X-ray films, scans, and other diagnostic images, as well as pictures of pathology specimens or photomicrographs, sharp, glossy, black-and-white or color photographic prints should be sent, usually 127 x 173 mm. Letters, numbers, and symbols on figures should therefore be clear and consistent throughout, and large enough to remain legible when the figure is reduced for publication.
- Figures should be made as self-explanatory as possible, since many will be used directly in slide presentations.
- Titles and detailed explanations belong in the legends--not on the illustrations themselves.
- Photomicrographs should have internal scale markers. Symbols, arrows, or letters used in photomicrographs should contrast with the background.
- Photographs of potentially identifiable people must be accompanied by written permission to use the photograph.
- Figures should be numbered consecutively according to the order in which they have been cited in the text.
- If a figure has been published previously, the original source should be acknowledged, and written permission from the copyright holder should be submitted to reproduce the figure. Permission is required irrespective of authorship or publisher, except for documents in the public domain. Accompanying drawings marked to indicate the region to be reproduced might be useful to the editor.
Legends for Illustrations (Figures)
- For image captions, Arabic numerals corresponding to the images should be used.
- When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, each one should be clearly identified and explained in the legend. The internal scale should be explained, and the method of staining in photomicrographs should be identified. Only the first letter of the first word in the figure title should be capitalized. All other words should be lowercase (except for proper nouns).
- Figure titles should be placed below the figure in Times New Roman, 10-point font size. If the figure does not fit within the page, the font size may be reduced accordingly.
- If the figure has a source, it must be indicated below the title in Times New Roman, 10-point font size. Only the first letter of the first word in the figure title should be capitalized. All other words should be lowercase (except for proper nouns).
Article Information Form
The article information form should be written after the text, before the references. Explain the following headings in detail.
Acknowledgments: The Acknowledgments section should follow the main text. If data from other published sources are used, the authors must obtain permission as explained above and state full acknowledgment as indicated by the copyright owners. Acknowledgments should also be made to research grants, technicians, and colleagues who assisted in the study; to individuals or companies who provided materials; and to mentors who provided advice and encouragement.
