SUBMISSION FILES

       TEMPLATES: 

• 📝 DMJ-template-cover_letter.docx
• 📝 DMJ-template-title_page.docx
• 📝 DMJ-template-main_text.docx

Manuscripts must be uploaded to the system as separate files as described below.

Copyright Transfer Form: The 📄 DMJ-copyright_transfer_form.pdf  must be signed by all authors in accordance with the authorship order. Submissions without a Copyright Transfer Form signed by all authors are not included in the review process.

Similarity Report: Authors are required to upload the similarity report obtained from a plagiarism software, such as iThenticate, etc., to the system at submission. In cases where plagiarism is detected, depending on the similarity rate, the editors' right to reject the manuscript and/or request corrections from the authors is reserved.

Ethics Committee Approval Document: The Ethics Committee Approval Document should be uploaded as a separate file for all research articles. In case reports, Informed Consent should be uploaded to the area reserved for the ethics committee approval.

Cover Letter: Type of the article, the statement that has not been published previously anywhere before, and/or not in the evaluation process for publication, if any, the people and institutions supporting the study financially, and the relationship of these institutions with authors (if not, there is no relationship) must be stated. The names, academic titles, institutions, contact information, and e-mail addresses of at least two reviewers suggested in relation to the subject of the manuscript and not related to the authors and their institutions should be provided. Editors' right to choose the reviewers is reserved.

Title Page: It must include the title of the article, names, academic titles, ORCID® numbers, institutions, e-mail addresses of all authors, and also name, correspondence address, phone number, and e-mail address of the corresponding author. If the manuscript has been presented previously in a scientific meeting, the name, date, and place of the meeting (if not, "not presented") should be stated. All required declarations must be filled out in detail.

Main Text: The title of the article, Abstract, Keywords (at least three), Main Text (sectioned according to the type of article submitted), References, Tables, and Figures should be included. To assist the double-blind peer review principle, the main text should be uploaded in two identical copies, one blinded and one unblinded, with the only difference being the anonymization of institution, study center, researcher, etc., using XXXXX in the "Material and Methods" section, and in other sections if needed. It is preferred and recommended to first prepare the unblinded version of the main text file in accordance with the Author's Guidelines, and then make a blind copy from this file. The blinded version should be uploaded to the "Full Text" field, and the unblinded version as a separate "Supporting File". This is necessary because reviewers can only access specific parts of the system due to the double-blind peer review principle.

Note: The documents listed above are mandatory files required to complete the submission. If any additional documents, such as figures, photographs, certificates, or supplementary materials, should be uploaded as separate files to the appropriate section during the submission.

Required information and titles to be included in the cover letter, title page and main text can be viewed in the templates. The templates can be downloaded and used directly. Submission files prepared by authors who do not want to use templates must include this information and titles.

• References are numbered consecutively according to the order of their first appearance in the text.
• The same reference number is reused if the source is cited again.
• Multiple references cited at the same point:
  • Consecutive numbers are given as a range, e.g., (3-6).
  • Non-consecutive numbers are separated by commas, e.g., (2,5,8).
• Citation numbers are placed outside periods and commas, and inside colons and semicolons, unless journal-specific rules state otherwise.
• Page numbers are generally not required; however, for direct quotations they may be included, e.g., (5 p196).

Author Listing Rule (applies to all reference types)

• Up to six authors: list all authors.
• Seven or more authors: list the first six authors followed by et al.

Reference List: General Rules

• The reference list appears at the end of the manuscript and includes only sources cited in the text.

• If available, DOI must be provided and is preferred over URLs.
• Personal communications and unpublished data should not be included in the reference list.
• Reference management software (e.g., EndNote®) may be used, but references must be submitted as plain text.

Sample Text and Reference List

Given that approximately 20% of the population smokes in most developed countries according to recent estimates (1,2), significantly higher smoking rates have been reported among disadvantaged groups. For example, smoking rates are 26-30% among low-income individuals (2,3), 32-50% among indigenous groups (3,4), 69-70% among homeless individuals (5,6), 35-90% among individuals with mental illness (7-9), and 72-79% among prisoners (10-12).

SCIENTIFIC POLICY

In terms of scientific publishing standards, manuscripts to be submitted should be prepared in accordance with the criteria of the International Committee of Medical Journal Editors (ICMJE, icmje.org/recommendations/), the World Association of Medical Editors (WAME, wame.org/policies), and the Committee of Publication Ethics (COPE, publicationethics.org/guidance/Guidelines).

• The manuscripts must have complied with the research and publication ethics. The authors are responsible for their article.
• The manuscripts are required to be unpublished and are not under review for publication elsewhere.
• The manuscripts must be submitted with the Copyright Transfer Form signed by all authors to begin the evaluation process. For authors' order, the signature order in the Copyright Transfer Form is based on.
• The corresponding author is responsible for the final version of the article on behalf of all authors.

ETHICAL POLICY

• Compliance with The Principles of Helsinki Declaration (wma.net/what-we-do/medical-ethics/declaration-of-helsinki/) is required in all studies including the “human” factor. In this kind of studies, authors must state that they perform the study in compliance with these principles, they have taken approval from the ethics committee of their institution, and the “informed consent” from people participating in the study, in the MATERIAL AND METHODS section.
• If the “animal” factor was used in the study, authors must state that they have protected the animal rights in line with the principles of Guide for the Care and Use of Laboratory Animals (grants.nih.gov/grants/olaw/guide-for-the-care-and-use-of-laboratory-animals.pdf) and they have taken approval from the ethics committee of their institution, in the MATERIAL AND METHODS section.
• In case reports, informed consent must be taken from patients.
• The information on the ethics committee approval should be indicated together with the name of the committee, approval date, and number, in the MATERIAL AND METHODS section.
• For all research involving human subjects, it must be stated that informed consent was obtained from all participants in compliance with The Principles of Helsinki Declaration (wma.net/policies-post/wma-declaration-of-helsinki-ethical-principles-for-medical-research-involving-human-subjects/), for participation in the study or use of their tissue (or a parent/legal guardian in the case of children under 18 and patients otherwise considered minors under local legislation). Consent is also required for the procurement of biomaterials for stem cell research and translation, including gamete donors in IVF studies. Studies involving vulnerable groups (i.e. individuals who are at higher risk of mistreatment or harm), with potential for coercion or exploitation (for example, prisoners or unconscious patients) or where consent may not have been fully informed (for example, due to a language barrier), will be considered at the Editor’s discretion under exceptional circumstances. Scientific research involving vulnerable groups can only be carried out if its aims and scope benefit those groups and meet their specific needs, and authors must be able to demonstrate this for their manuscript to be considered for publication.
  
• If there is a direct-indirect commercial relation or an institution giving financial support in the study, authors must state that they have no commercial relationship with the commercial product, medicine, company, etc. used, or if any, what kind of a relationship they have (consultant, other agreements), in the cover letter to the editor.
• The authors are responsible for reporting all personal and financial relationships that may be related to the study. It is necessary to state clearly whether there is any conflict of interest related to the submission and/or evaluation of the manuscript.
• Compliance of the manuscripts with the scientific and ethical rules is the responsibility of the authors.

CLINICAL TRIALS

Duzce Medical Journal requires the prospective registration of clinical trials to a publicly accessible registry. The name of the registry, date, and registration number should be provided at the end of the abstract. Appropriate public registries are listed on the International Committee of Medical Journal Editors (ICMJE) website (icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html) and the WHO International Clinical Trials Registry Platform (ICTRP, who.int/clinical-trials-registry-platform).

DATA SHARING POLICY

Authors are required to provide a data sharing statement for manuscripts that report the results of a clinical trial. The data sharing statement should indicate the items according to the International Committee of Medical Journal Editors (ICMJE) data sharing policy: "data sharing statements must indicate the following: whether individual deidentified participant data (including data dictionaries) will be shared (“undecided” is not an acceptable answer); what data in particular will be shared; whether additional, related documents will be available (e.g., study protocol, statistical analysis plan, etc.); when the data will become available and for how long; by what access criteria data will be shared (including with whom, for what types of analyses, and by what mechanism)". Authors are recommended to check the illustrative examples of data sharing at icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html.

REPORTING GUIDELINES

Incomplete reporting of experimental details, study rationale, methodological design, and research outcomes can greatly compromise the validity, accuracy, and reproducibility of scientific results. Thus, authors need to ensure that their manuscript adheres to certain standards of reporting. Duzce Medical Journal encourages authors to refer to the guidelines when preparing their manuscripts. For further information on the reporting guidelines, and reporting guidelines for main study types, authors are suggested to refer to the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) Network website (equator-network.org/). Where the authors use a checklist, this should be duly acknowledged in the Material and Methods section of the manuscript.

Authors whose first language is not English are encouraged to have their manuscript checked by getting help from a native English speaker, and/or using professional language editing (proofreading) services. There are some specialist language editing and proofreading companies that offer language editing services. Duzce Medical Journal neither endorses nor takes responsibility for these services. This is not mandatory but may help to ensure that the content of your manuscript is fully understood by editors and reviewers. Please note that the use of a language editing service is not a requirement for submission and does not imply or guarantee that the manuscript will be selected for peer review or accepted for publication. The editors reserve the right to reject without review those that cannot adequately be assessed because of a poor standard of English.

CONFLICT OF INTEREST

The Duzce Medical Journal requires that each author, reviewer, and editor in any of the processes (submission, peer review, editorial decision, and communication between authors, reviewers, and editors) must disclose to the editor-in-chief any conflict of interest related to family, personal, financial, political or religious issues as well as any competing interest that could unduly influence his or her responsibilities (academic honesty, unbiased conduct and reporting of research, and integrity of decisions or judgments) in the publication process. Whether or not a conflict of interest and financial support exist, they must be declared on the cover letter and title page as well as at the end of the manuscripts. If a reviewer or a section editor has a conflict of interest and/or believes that it is not appropriate to be a reviewer or an editor for a given manuscript, the reviewer or the editor should resign from the assignment. The Editorial Board members of the Duzce Medical Journal, who handle submissions and recommend decisions to the Editor-in-Chief (EIC, Deputy Editor, and Section Editors) may also submit their own manuscripts to the journal as all of them are active researchers and scientists. However, they cannot take place at any stage in the editorial decision of their manuscripts in order to minimize any possible bias. They will be treated like any other author, and if any, final acceptance of such manuscripts can only be made by the positive recommendation of at least two external reviewers, who are not members of the decision-making Editorial Board. Authors should not contact any of the section editors during the review process. All necessary information regarding the process of a manuscript can be obtained from the editorial office. However, the names of the section editor and the reviewers are not given to the author(s). Due to the double-blinded review principles of the Duzce Medical Journal, the names of authors and reviewers are not known to each other.

PLAGIARISM

Plagiarism is a serious problem and the most common ethical issue afflicting medical writing. The Duzce Medical Journal does not allow any form of plagiarism. Authors are required to upload the similarity report obtained from plagiarism software such as iThenticate etc. to the system at the submission stage. Depending on the similarity rate, editors' right to reject the manuscript and/or request a correction from authors is reserved. In accordance with journal policy, submitted manuscripts are also screened with plagiarism software (iThenticate, etc.) by the editorial office to detect instances of overlapping and similar text. High similarity scores may lead to the rejection of a manuscript before and even after acceptance. Depending on the type of manuscript and the percentage of similarity score taken from each article, the overall similarity score is generally expected to be less than 20-25%.

PREPRINT

The studies presented in a non-commercial preprint server are allowed to submit. In such a case, authors must provide the preprint server deposition of their manuscript with its DOI during the submission. If the manuscript is accepted and published in the Duzce Medical Journal, it is the responsibility of the authors to update the archived preprint and link it to the published version of the article. The preprint must be removed in the case of acceptance to leave only the final version online.

CHANGE OF AUTHORSHIP

Any request to change the author list after submission, such as a change in the order of the authors or the deletion or addition of authors, is subject to the Editorial Board’s approval. To obtain this approval, the detailed reason for the change of authorship with a new copyright transfer form signed by all authors (including the new and/or removed author) should be presented to the Editorial Board. Please note that this does not guarantee that the change will be approved. The Editorial Board's right to approve or decline the request is reserved.

CORRECTIONS

All the correction requests made to a published article will be with the authorization of the Editorial Board of the Duzce Medical Journal. Editorial Board will decide the magnitude of the corrections. Depending on the magnitude and the content of the correction, the following cases are applicable.
Erratum: An error that affects the integrity of the version of the record, the reputation of the authors, or the reputation of the journal, is termed Erratum. An Erratum is a statement by the authors of the original article that briefly describes any correction(s) resulting from errors or omissions. Any effects on the conclusions of the manuscript should be noted. The corrected article is not removed from the journal, but notice of erratum is given. The Erratum is made available to all readers and is linked to the corrected article.
Addendum: An addendum is a notification of an addition of information to an article. An addendum is published only rarely and when the editorial board decides that the addendum is crucial to the reader’s understanding of a significant part of the published article. The addendum does not contradict the original article, but if the author inadvertently omitted significant information available at the time, this material can be published as an addendum. An addendum may be peer-reviewed, according to journal policy, and are normally subject to oversight by the Editorial Board of the Duzce Medical Journal. The addendum is made available to all readers and is linked to the original article to which they relate.

RETRACTIONS

Retraction of a manuscript will be permitted only for the most compelling and unavoidable reasons. For retraction of a manuscript, authors need to submit a detailed explanation, signed by all authors mentioning the reason for retraction to the Editorial Office. After receiving the retraction request, the Editorial Board of the Duzce Medical Journal will investigate the reason for the retraction. The Editorial Board's right to approve or decline the request is reserved. Authors must not assume that their manuscript has been retracted until they have received appropriate notification to this effect from the editorial office. If the reason finds to be acceptable, the author is allowed to retract the manuscript without paying any retraction penalty. To protect the integrity of the record, the retracted article is not removed from the journal, but notice of retraction is given, also it is made available to all readers, and is linked to the retracted article. In rare and extreme cases involving legal infringement, the Editorial Board of the Duzce Medical Journal may redact or remove an article. Bibliographic information about the article will be retained to ensure the integrity of the scientific record.

APPEALS and COMPLAINTS

Appeal and complaint cases are handled by the Editorial Board of the journal. Appeals should be based on the scientific content of the manuscript. The final decision on the appeal and complaint is made by Editor-in-Chief. An Ombudsperson or the Ethical Editor may be assigned to resolve cases that cannot be resolved internally. Authors should get in contact with the Editor-in-Chief regarding their appeals and complaints via e-mail at duzcetipdergisi@duzce.edu.tr.
