JPEN Author Guidelines
The Journal of Parenteral and Enteral Nutrition (JPEN) is the premier scientific journal of clinical nutrition and metabolic support. It publishes original peer-reviewed studies that define the cutting edge of basic and clinical research in the field. It explores the science of optimizing the care of patients receiving enteral or IV therapies. JPEN is an official journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.).
JPEN accepts contributions on a wide range of issues within the field of clinical nutrition covering topics such as:
- High quality evidence supporting best clinical practices in human populations
- Translational research investigating novel strategies that optimize nutrition support therapy
- Basic research enhancing understanding of cellular and molecular nutrient utilization, metabolism, and pathophysiology
- Critical reviews of current knowledge in nutrition and metabolism
- Educational and training strategies establishing best learning outcomes and fostering a robust community of nutrition support practitioners
- Innovative techniques, materials, and devices demonstrating improved outcomes
- Case reports/series informing novel hypothesis generation and clinical insight
Manuscripts may be submitted in any of the following categories: Original Communication, Brief Communication, Case Report/Series, Letter to the Editor, Tutorial, Review, Clinical Guidelines*, and Book Review.
*Please note: Submission of Clinical Guidelines is restricted to A.S.P.E.N.’s Clinical Guidelines Editorial Board. To submit suggestions for future topics, please email the Clinical Guidelines Editor in Chief Dr Charlene Compher at email@example.com.
Original Communications are comprehensive, fully documented reports of original research. They should present complete results with a detailed Materials and Methods section. They should also include a structured abstract (200–250 words) and a Clinical Relevancy Statement, which is a brief statement allowing the reader to quickly identify the clinical applicability of the research presented in the article. Please see an example here. Original Communications usually contain between 6,500 and 8,000 words of text. They may also include tables, figures, and other supplemental information.
Brief Communications are preliminary reports of original, significant research results. Communications are typically no longer than 4,500 words, including all literature citations. Formulas, figures, and tables may also be added. Brief communications should include a structured abstract and a Clinical Relevancy Statement, which is a brief statement allowing the reader to quickly identify the clinical applicability of the research presented in the article. Please see an example here.
Reviews are complete, critical evaluations of the current state of knowledge in a particular subject area. In addition to presenting and discussing research accomplishments, reviews also highlight remaining challenges and possible future research developments in a particular field. Although reviews are generally commissioned by the Journal, unsolicited submissions are also welcome. Reviews should consist of a maximum of 20,000 words, including text, footnotes, literature citations, tables, figures, and legends. An unstructured abstract of 200–250 words is required.
Letter to the Editor
Letters to the Editor provide substantive comments on papers published in the Journal or on topics of broad interest to the clinical nutrition and metabolic support community. Letters should be submitted no later than six weeks after publication of the paper discussed in the Letter. Letters to the Editor are generally no more than 500 words. All letters accepted for publication are edited, and the edited versions are reviewed by authors for approval prior to publication.
Tutorials are aimed at providing background knowledge to an audience unfamiliar with the topic covered in the article. Tutorials foster the cross-fertilization of knowledge among interdisciplinary teams of professionals involved in nutrition support; they may be used as educational tools for dietitians and clinical nutritionists working in collaboration with physicians and other medical practitioners.
Tutorials usually contain between 6,500 and 8,500 words; they may contain historical or biographical information and supplementary data, including videos. Tutorials should have an unstructured abstract.
Authors of tutorial articles are required to provide:
- a glossary of technical words or concepts specific to the subject matter covered in the tutorial
- a Further Reading list (e.g., books, online courses)
- a short bio of the author (about 200 words) that includes research interests (for single-author tutorials only)
- a minimum of 2 color images to be used for the online version of the article (black and white versions will appear in the print version unless authors choose to pay color printing fee).
Commentaries are short, narrowly focused articles usually commissioned by the Journal. They provide critical or alternative viewpoints on key issues and generally consist of a discussion of an article recently published in the Journal. Although commentaries are generally commissioned by the Journal, unsolicited submissions are also welcome.
Case Report/Case Series
Case Reports (either a single case or a case series) focus on nutrition management with a detailed description of diagnosis, nutrition intervention, findings, and outcome. They should offer new insight into the diagnosis or treatment of a disease. All case reports will be evaluated based on clinical interest and educational value.
Case Reports generally are a maximum of 2,000 words. They include a concise review of literature, with a number of references generally ranging from 6 to 10. An unstructured abstract is welcome but not required.
Book Reviews are generally commissioned. Nevertheless, suggestions for books to review are welcome. Additionally, if you wish to review a book, please contact the editorial office at firstname.lastname@example.org.
Manuscripts must be submitted online at http://mc.manuscriptcentral.com/jpen. There is no submission fee. Author instructions and forms are available at this site. Please note that your author account will be the same for JPEN as well as Nutrition in Clinical Practice (NCP), because authors submitting manuscripts for publication in JPEN are submitting their manuscript to the A.S.P.E.N. journals’ office database, accessible to the Editors of both A.S.P.E.N. journals.
Manuscripts are considered with the understanding that they have not been published previously except in abstract form or as preliminary observations and are not under consideration by another publication. Each submission is given unbiased consideration and evaluated without regard to the race, gender, ethnic origin, or citizenship of the author(s). We treat all articles as confidential until they are published in the Journal.
One corresponding author should be designated for each manuscript. This person will be responsible for submitting the Transfer of Copyright form on behalf of all other authors (in cases where no authors are employees of the federal government). This person will also be responsible for all correspondence with the editorial office and will also be responsible for responding to inquiries from readers after the publication of the manuscript. Please be mindful that contact information should include a permanent address so that readers can easily be in touch with the corresponding author after publication as needed.
To select a different corresponding author after the acceptance of the manuscript, a written request from both the new and previous corresponding author must be submitted to the editorial office at email@example.com.
Conflict of Interest
When a paper is submitted to JPEN, all authors must disclose any personal or financial conflicts of interest within the online submission system. A conflict of interest may exist when an author (or his or her institution or employer) has financial or personal relationships or affiliations that could influence (or bias) the decisions, work, or manuscript of the author(s). All authors are required to disclose all potential conflicts of interest, including specific financial interests and relationships and affiliations (other than those affiliations listed in the author page of the manuscript) relevant to the subject of their manuscript. Authors should make full disclosures as appropriate.
Authors are expected to provide detailed information about all relevant financial interests and relationships or financial conflicts within the past 5 years and for the foreseeable future. Examples include employment/affiliation, grants or funding source, consultancies, honoraria, speakers' bureaus, stock ownership or options, expert testimony, and royalties. Also included are patents filed, received, pending, or in preparation, particularly those present at the time the research was conducted and through publication, as well as other financial interests that represent potential future financial gain. Authors with questions should contact the editorial office at firstname.lastname@example.org.
For published manuscripts, each author's disclosure of conflicts of interest and relevant financial interests and affiliations and declarations of no such interests will be published.
A.S.P.E.N. Policy on Academic Misconduct. The Society takes seriously its role in safeguarding the research record and ensuring the reliability of our publications. A.S.P.E.N.’s approach to academic misconduct is primarily preventive, asking authors to provide information about prior submission of their work and to use citations to traceable sources as well as conducting our internal refereeing and single-blind peer review processes. For more information, read the A.S.P.E.N. Policy on Academic Misconduct.
Authorship. Authorship should be provided to all individuals, and only those individuals, who meet the following published criteria from the International Committee of Medical Journal Editors:
- substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data;
- drafting the article or revising it critically for important intellectual content, and;
- final approval of the version to be published.
Ethical Board Approval
All studies that involve human subjects must be approved or deemed exempt by an official institutional review board, ethical board, or equivalent in accordance with local regulations; this should be noted in the Methods section of the manuscript. Also see the Informed Consent section below.
Animal experiments require full compliance with local, national, ethical, and regulatory principles, and local licensing arrangements.
JPEN takes a firm stance against plagiarism and other forms of academic misconduct. Submitted manuscripts will be subject to plagiarism screening through the use of a plagiarism detection software. Any manuscripts that are found to be plagiarized, in whole or in part (including self plagiarism), will be subject to immediate rejection, and the author’s institution may be contacted for further action. For more information about what constitutes plagiarism, please see the A.S.P.E.N. Policy on Academic Misconduct.
