Aims and Scope

The Portuguese Journal of Internal Medicine (PJIM) is the official body of the Portuguese Society of Internal Medicine (PSIM).

The journal is dedicated to promote science and the practice of Internal Medicine, covering all aspects of Internal Medicine. To this end, it publishes peer-reviewed works, according to the following categories: Originals, Reviews, Viewpoints, History of Medicine, Short Communications, Letters to the Editor, Medicine in Images and Case Reports. The journal also publishes news and articles on the activities and policies of the Portuguese Society of Internal Medicine.

The PJIM adopts the editorial freedom definition of the ICMJE described by the World Association of Medical Editors, which states that the editor-in-chief assumes full authority over the journal's editorial content. The PSIM, as the owner of PJIM, does not interfere in the process of evaluation, selection, planning or edition of any manuscript, having Editor-in-Chief total editorial independence.

The Journal is governed according to the biomedical edition standards of the International Committee of Medical Journal Editors (ICMJE), available at http://www.ICMJE.org and the Committee on Publication Ethics (COPE).

The editorial policy of the Journal follows the Editorial Policy Statements issued by the Council of Science Editors, available at http://www.councilscienceeditors.org/resource-library/editorial-policies/white-paper-on-publication-ethics/ which covers the responsibilities and rights of the editors of journals with scientific arbitration.

Editorial Policies for Authors

1. Authorship Criteria and Form

As stated in the ICMJE Requirements, authorship requires a substantial contribution to the manuscript and it is necessary to specify, in a cover letter, the contribution of each author to the work; author declaration signed by each author (Declaration of Consent).

All those designated as authors must meet the four criteria for authorship and all those who meet the four criteria must be identified as authors. Collaborators who do not meet the four criteria for authorship but have contributed to the study or manuscript must be recognized in the Acknowledgments section, specifying the contribution.

Each manuscript must have a "Corresponding Author". However, all authors must have significantly participated in the work to take public responsibility for the content and credit of authorship.

Authors must provide an ORCID iD at the time of submission by entering it in the user profile in the submission system.

Authorship is based on the following 4 criteria:
1)Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
2)Drafting the work or revising it critically for important intellectual content; AND
3)Final approval of the version to be published; AND
4)Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

In addition to being accountable for the parts of the work, an author should be able to identify which co-authors are responsible for other specific parts of the work.

The acquisition of funding, data collecting or general supervision of the working group alone does not qualify a contributor for authorship.

Any changes to authorship after submission must have written approval from all authors. Changes to authorship or authors' order are not received after the manuscript has been accepted.

If a medical writer has been involved in the conception of the manuscript, it is mandatory a signed declaration by the corresponding author declaring the funding. This information must be added to the Acknowledgments section.

We require the medical writer to provide a signed statement allowing to be named in the Acknowledgments section.


2. Role of the Corresponding Author

The corresponding author will act on behalf of all co-authors as the primary correspondent with the editorial team during the submission and review process.

The corresponding author is responsible for the communication with the journal during submission, peer-review and publication process. It is also responsible for ensuring all the journal's administrative requirements (providing authorship details, ethics committee approval, conflict of interest forms, informed consent).


3. Informed Consent

The authors are responsible for obtaining informed consent from each individual presented in photographs, videos, detailed descriptions or in radiographs or ultrasound, even after an attempt to conceal their identity. The names, initials or other forms of identification must be removed from photographs or other images. Personal data, such as profession or residence, must be omitted except when they are epidemiologically relevant to the work. The authors must ensure that they do not provide data that allow explicit identification or, if not possible, must obtain the informed consent of the stakeholders (provide a template).


4. Ethical Conduct and Human and Animal Rights

The authors must ensure that the study they are submitting follows the ethical and legal principles during research and publication, mainly the recommendations of the Helsinki Declaration revised in 2013 from the World Medical Association (http://www.wma.net/en/20activities/10ethics/10helsinki), the ICMJE (www.icmje.org) and the Committee on Publication Ethics (COPE) (http://publicationethics.org/resources/guidelines). In appropriate cases, the authors must demonstrate that the research was approved by the ethics committee of the involved institutions and that recommendations were followed. This information must be included in the text of the article. Any suspected misconduct will be investigated and reported.


5. Awards and Previous Presentations

The prizes and presentations of the study, before submission of the manuscript, must be mentioned.


6. Conflict of Interest and Funding Sources

All funding sources must be mentioned as well as their influence on the design of the manuscript or the submission decision for publication.

The accuracy and exactness of the contents, as well as the opinions expressed, are the sole responsibility of the authors.

The authors are responsible for disclosing all financial and personal relationships that might bias their work.

To prevent ambiguity, the authors must explicitly mention any conflicts of interest.

All authors must complete and submit the Declaration of Conflicts of Interest, in Minutes of Consent (according to ICMJE Form for Disclosure of Potential Conflicts of Interest) available at: http://revista.spmi.pt/backoffice/files/minuta_de_consentimento.pdf.

This information will be kept confidential during the review by the reviewers and will not influence the editorial decision but will be published if the article is accepted.


Submission

The electronic submission substantially reduces both editorial and review time and total publication time. The authors need to submit the manuscripts online at http://revista.spmi.pt/site/index.php

All contacts between the authors and the journal will be held by e-mail.

Before submitting the manuscript, the authors must ensure all necessary authorizations for the publication of the submitted material.


Cover letter for submission

Before submitting an article, the authors must prepare a cover letter, drafted and signed by the corresponding author, where he/she must explain why the manuscript is of interest to the journal and why it should be published. It also must include that the article it is an original, that it was only submitted to the journal, that has not previously been published and that complies with the instructions to the authors still, must declare that the work is in accordance with the ethical and legal principles (complied with the recommendations of the Helsinki Declaration of the World Medical Association/was evaluated and approved by the ethics committee, if original study); and the funding sources. A declaration of responsibility (Consent Form) written and signed individually by each of the authors of the work, and in which each one must declare that it fulfills the authorship criteria and specifies its contribution to the work, as well as the Declaration of Conflict of Interest, are required.

Peer-review process

The PJIM follows a strict single-blind peer-review process.

All manuscripts are initially evaluated by the members of the Editorial Team and if they donít comply with the instructions they can be immediately rejected.

All manuscripts are evaluated by the editor-in-chief. They can be rejected at this stage, without being sent to the reviewers.

The editor-in-chief is responsible for the final acceptance.

In the evaluation, articles can be:
a) Accepted without changes;
b) Accepted after proposed modifications by the reviewers;
c) Refused

Only the manuscripts containing original material that was not yet published, in whole or in part, and that was not submitted for publication elsewhere will be accepted.

After submitting the article on the platform of the PJIM website, the status of the article is changed to "Submitted by the Author".
This information can be found in the list of articles under review.
After validation of the Cover letter submission and the Consent Form along with the Statement on authorship signed by the authors and the Conflict of Interest Form, all articles will be analyzed by the Editorial Board and sent to two reviewers, if they are in accordance with the instructions and follow the editorial policy.

Reviewers must keep confidentiality and will appreciate the content of the article and as well as the importance of its publication.
Within a maximum period of four weeks, the reviewer shall respond to the editor-in-chief indicating his/her comments regarding the manuscript and his/her suggestion as to accept, review or reject the manuscript. Within ten days the editorial board will make a decision that may be: acceptance without modifications; sending to the author the reviewers' comments to proceed as indicated; rejection.

When changes are proposed, the authors have fifteen days (a term that can be extended by authorsí request) to submit the new revised version of the manuscript, including comments from the reviewers and editorial board. The changes should be highlighted with a different color.

The editor-in-chief has 10 days to make the decision on the new version: to reject or accept the new version, or to send it to one or more reviewers.

In case of acceptance, in any of the previous phases, the decision will be communicated to the corresponding author.

In the review phase of typographical proofs, substantial changes to the articles will not be accepted and it may imply subsequent rejection by decision of the editor-in-chief. In all cases the reviewers' opinion will be fully communicated to the authors within six to eight weeks from the date of reception of the manuscript.

In the fourth edition of each year, the names of the reviewers who have collaborated with PJIM will be published, being awarded one star for every 3 years of consecutive activity in the journal.
Although the editors and reviewers are making efforts to ensure the technical and scientific quality of the manuscripts, the sole responsibility for the content lies within the authors (including accuracy and precision of the comments, as well as the opinions expressed).


How to respond to peer-review?

  1. All reviewers' comments should be answered point by point;
  2. Copy the reviewers' comments to a Word document and respond to each comment;
  3. List each comment entirely, followed by the answers;
  4. We suggest the format:
    Reviewer 1 comment 1:
    Answer:
  5. Also submit 2 copies of the manuscript:
  1. With flagged changes (track changes/record changes)
  2. Clean, with all included revisions


Typographical proofs

The typographical proofs will be sent to the authors, indicating the period of revision according to PJIM's publication needs. The review must be approved by the corresponding author. The authors have five days to review the text and report any typos. At this stage, authors cannot make any substantial changes to the article, in addition to corrections of typographical errors and/or minor spelling errors.

Failure to respect the proposed deadline releases PJIM from accepting the authorsí review and may be carried out exclusively by the PJIM services.


Errata and Retractions

The PJIM publishes changes, amendments or retractions to a previously published article if, after publication, errors or omissions that may influence the interpretation of data or information are identified. Amendments after publication shall take the form of errata.
