Instructions for authors (PDF)

 

MANUSCRIPT SUBMISSION

The PJP provides an online platform at https://pjp.spp.pt, where authors can submit their manuscripts and follow the editorial process.

To submit a manuscript, the authors must follow the following steps:

  • Create a user account by registering at the website of the PJP (https://pjp.spp.pt)
  • Manuscript submission: after the registration is complete, authors can log in, submit, and track the progress of their manuscripts. Each submission is identified by a unique identification number.

Questions should be directed to the support team at pjp@spp.pt.

Fast-track publication

A fast-track system is available for urgent manuscripts. After submitting their manuscript on the online submission platform, authors should send an e-mail to the Editor-in-Chief (editorinchief.pjp@spp.pt) indicating why they consider the manuscript suitable for rapid publication. The Editor-in-Chief informs the author about his decision within 48 hours. If deemed inappropriate for the fast-track publication, the manuscript can be considered for the standard revision process. In this case, the authors will have the opportunity to withdraw their submission.

Online First

Online First service allows final articles to be published before being included in a PJP Issue.

Press proof

After acceptance, the manuscripts will be sent to the authors in the proof stage. The corresponding author must correct typographical errors and/or approve the document within 72 hours. Substantive changes are not accepted.

 

REQUIRED DOCUMENTS

Before submitting a manuscript, authors must prepare the following documents:

  • The Cover letter (template available here) should be written and signed by the corresponding author and include the relevant data to justify the article’s publication and its originality. Moreover, the cover letter must state that the manuscript has not been submitted to any other journal than the PJP, has not been previously published, adheres to the structure and style of the PJP, complies with ethical and legal guidelines, and indicates sources of funding (if applicable).
  • The Authorship responsibility statement (template available here) should be filled out by the corresponding author and signed by all authors, specifying the contribution of each author and his/her responsibility for the data validity of the article’s content. Finally, each author should confirm the copyright transfer to the PJP. Although editors and proofreaders make all efforts to ensure the scientific and technical quality of the manuscripts, the ultimate responsibility of the content (including accuracy and precision of the observations and opinions/ideas expressed) is the sole responsibility of the authors to whom the article’s intellectual property belongs.
  • Declaration of Conflicts of Interest (ICMJE template, available at http://www.icmje.org/disclosure-of-interest/). Authors must declare any potential conflicts of interest that could cause a bias (or be seen as a bias) in the conduct of their work in the individual ICMJE template declaration. Consequently, authors must disclose all financial and personal relationships related to the submitted work. They should also identify any benefits associated with the article’s publication, including stock or economic interests in companies or other institutions, wages or awards, grants or other forms of funding, consulting, patent rights, or other financial relations. The existence of conflicts of interest in publishing an article does not constitute a reason for rejection, as long as the said conflicts are appropriately declared. For any queries on what constitutes a relevant financial or personal interest, the authors should contact the Editor-in-Chief.

When applicable, authors should also submit:

  1. Informed consent of each participant;
  2. Informed consent of each person appearing in photographs, even after taking appropriate measures to preserve anonymity;
  3. Authorization to reproduce/use previously published material (for example, illustrations);
  4. Declaration of approval by the ethics committees of the institutions involved.

All documents must be provided during the submission process, preferably through the online platform or by e-mail (pjp@spp.pt).

Any personal, professional, political, religious, or other relationship that is likely to influence the article should be reported as well. This information will not affect the editorial decision. They will be kept confidential during the manuscript review and will be published if the paper is accepted.

 

GENERAL REQUIREMENTS

All articles submitted to the journal must comply with the PJP instructions, otherwise, correction requirements will result in publication delay.

  • Manuscripts must be provided as a standard document format (e.g., .doc, .docx).
  • Figures must be provided in a standard image format (e.g., JPEG, TIFF, PNG) (with high resolution, 800 dpi for graphics and 300 dpi for photographs).
  • Tables must be provided as an editable Microsoft Word document (i.e., .doc, .docx) or an editable Microsoft Excel spreadsheet (i.e., .xls, .xlsx) containing only text and no formulas.
  • Manuscripts should be double spaced.
  • Continuous line numbers must be included.
  • Single spaces are needed after periods.

Following pages

The article’s main text should include the following sections, according to each article type.

The Introduction should contain the scientific arguments that contextualize the subject matter, substantiate the realization of the study, and identify its objectives. Therefore, this section should only have the necessary references for these purposes.

In the Methods, the author should describe:

  1. Study sample or population (specifying definition and means of identification, recruiting, and selection);
  2. Study location (both time and space) without disclosing the author’s identification or the institution where the study took place;
  3. Study design;
  4. Data collection methods;
  5. Data analysis methods. Statistical methods adopted should be described in sufficient detail. The computer program (including its version and the manufacturer) used for data analysis should be mentioned.

Ethical considerations should follow this section and include such information as the approval of ethics committees (and ethics code, if available) and informed consent, if applicable.

The Results should be presented in the text and complemented by illustrations (tables, figures), and redundant information should be avoided.

The Discussion should not include repeated information presented in the other article sections. Instead, it should focus on the comparison of data from the literature, innovative aspects, and the conclusions that result from them. Only the indispensable references to discuss the study results should be included in the discussion section of the study. At the end of the discussion, strengths and limitations should be pointed out. The conclusions should be coherent with the objectives. Authors should avoid statements and conclusions that are not fully supported by the results.

Acknowledgments, financing sources, awards, and previous presentations should be stated at the end of the text and precede the references.

References should be indicated in the text in order of entry, as superscript Arabic numerals. Authors may be identified, but the reference number must always be given. Unpublished data and personal communications should be referenced directly in the text. The citation of a reference as "in press" implies that it has been accepted for publication. References should comply with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" (http://www.nlm.nih.gov/bsd/uniform_requirements.html). Unless not available, DOI (Digital Object Identifier) is mandatory at the end of the reference.

After the references, the illustrations should be presented individually on a new page, in the following order: tables and figures numbered as referenced in the text. A self-explanatory succinct and clear caption should accompany each table and figure. Table footnotes should contain information relevant to specific cells of the table. If needed, these symbols can be used in order: *, †, ‡, §, ||, ¶, **, ††, ‡‡

The inclusion of previously published figures or tables requires authorization by the copyright holder (author or editor).

Footnotes should be avoided. When necessary, they must be numbered consecutively and appear at the bottom of the appropriate page.
