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.
• TJIM adopts a continuous publication model. Once an article is accepted, it is laid out and published after print approval.
• The articles are in English.
• Manuscripts to be published must be sent via the “Submit Article” page.

Article Submission Phase

Required files to be uploaded when submitting an article:

1. A Word file of the article prepared in accordance with the editorial guidelines (No information about the authors should be included. This file will be sent to the reviewers in accordance with the double-blind review policy.)
2. The "Title Page" must be fully completed and uploaded to the system.
3. Copyright Agreement and Author Acceptance Form 
4. A similarity report must be uploaded to the system.
5. The approved version of the Ethics Committee Permit must be uploaded to the system. If the study does not require ethics committee approval, upload a file indicating this. In addition, this approval (name, date, and number of the committee) must be stated in the "Article Information Form" at the end of the study.

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.

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.

Types of Papers

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 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

• Articles should be written in a single line using Microsoft Word, leaving 2.5 cm margins on all sides.
• Paragraphs should not be indented.
• A full-length article should be no more than 6,000 words, excluding references and tables.
• For equations, use either the equation editor or MathType.
• For tables, use the table function, not spreadsheets.

Download the WORD file for the sample file.

Title page 

Please complete this mandatory file when uploading your article, according to the instructions, see  Title Page.

Title

A title that describes the article and is not too long is preferred. Only the first letter of each word in the title should be capitalized.

Authors

Author names must be clearly written. Abbreviations must not be used. Each author's ORCID ID number must be written. Each author's institution must be listed in the order Department, Faculty, University, City, and Country. If the institution is present, its ROR ID must be written after the address. (Because the journal uses a double-blind peer-review policy, it is recommended that you enter author information in the "Title Page.docx " field during the initial submission.)

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 Objective, Methods, Results, and Conclusion.

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.
