The Portuguese Journal of Pediatrics (PJP), founded in 1938, is the official journal of the Portuguese Society of Pediatrics (SPP).
The PJP is a scientific double-blind peer reviewed quarterly journal published online in English. The journal aims to publish high quality articles on clinical and experimental pediatrics and maternal fetal conditions.
This journal publishes a variety of articles including original articles, review articles, case series, case reports, images in Pediatrics, editorials, letters to the editor, guidelines, perspectives, and other content to improve clinical practice.
The PJP provides an online platform at http://publisher. portuguesejournalofpediatrics.permanyer.com, where authors can submit their manuscripts and follow the editorial process. 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.
To avoid duplications in the system, please refrain from creating a new request when resubmitting your modified files. You should continue using the same reference until your manuscript completes the editorial process.
Questions should be directed to the support team at: permanyer@permanyer.com.
Ahead of print
The ahead of print service allows final articles to be published before being included in a PJP Issue.
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:
a) Informed consent of each participant;
b) Informed consent of each person appearing in photographs, even after taking appropriate measures to preserve anonymity;
c) Authorization to reproduce/use previously published material (for example, illustrations);
d) Declaration of approval by the ethics committees of the institutions involved.
All documents must be provided during the submission process, through the online platform.
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.
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).

Numeric ranges must be separated by "–" (for example, 25-30). In addition, a space between a value and the respective unit of measurement should be used (for example, 25-30 mg), except for percentages (for example, 3%) and temperature values (for example, 5ºC) which must be presented without a space.
Units of Measure
Units of measurement in the International System of Units should be used.
Species names
The author should write the names of species in italics (e.g. Homo sapiens). The name of the genus and species must be written in full, both in the title of the manuscript and the first mention in the manuscript.
Genes, mutations, genotypes, and alleles
These must be written in italics. The recommended names should be used by consulting a genetic nomenclature database (e.g. HUGO for human genes). Sometimes, it is advisable to indicate the gene synonyms the first time it appears in the text. Gene prefixes, such as those used for oncogenes or cellular localization, should be written in italics (e.g. v-fes, c- MYC).
Multimedia Files
The multimedia files must be sent in a separate file with the manuscript. The multimedia material must respect the production quality standards for publication without needing modification or editing. Acceptable file formats include MPEG, AVI, or QuickTime.

Referencing style
The PJP follows the AMA Manual of Style (11th Edition).
The editorial process consists of 6 stages:
1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.
2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.
3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.
4. Editorial review (maximum 7 business days): its objective is to make a decision based on the opinion of peer reviewers. The opinion can be rejected, major changes, minor changes or accepted. In the case of major or minor changes, it will be submitted again for evaluation by the initial peer reviewers.
5. Final edition (6 weeks): its objective is the technical and linguistic edition (and translation), layout of galleys, DOI assignment, and correction by the author.
6. Advanced publication: All manuscripts will be published ahead of print on the journal's website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.
The corresponding author will receive proofs of the article for revision and correction of terminology errors, or any other updates related to facts/figures. As the article will already have been edited according to the journal’s internal editorial guidelines, style corrections will not be accepted. The corresponding author will receive an email with the article in PDF format, on which they can leave their comments. Authors will need to have Adobe Reader (version 9, or a later version), downloadable for free). For other system requirements, please visit the Adobe website.
Alternatively, authors may list their corrections and submit them via email. Any major changes at this stage will be subject to the approval of the Editor. Authors should make sure to include all changes in a single email, as we cannot guarantee the inclusion of subsequent corrections.
The proof review is the responsibility of the author.
