NCP Author Guidelines

General Information

Nutrition in Clinical Practice (NCP) is a peer-reviewed, interdisciplinary journal that is dedicated to publishing articles about the scientific basis and clinical application of nutrition and nutrition support. NCP is published bi-monthly and is an official journal of the American Society for Parenteral and Enteral Nutrition (ASPEN).

The aims of NCP are to disseminate current research on clinical nutrition and nutrition support from a interdisciplinary viewpoint and bridge the gap between research and practice. NCP contains comprehensive reviews, clinical research, case observations, and other types of papers written by experts in the field of nutrition and health care practitioners involved in the delivery of specialized nutrition support.

NCP Editors determine specific nutrition themes for each issue and solicit articles for those themes. Unsolicited articles based on the identified themes or any other topic related to clinical nutrition and nutrition support are also welcome. In addition, NCP publishes ASPEN Standards of Practice and Position Papers.

The editorial board for NCP is led by Dr. Jeanette Hasse. She is supported by esteemed Associate Editors and Editorial Board Members recognized for their research and experience in specialized nutrition support.

Manuscript Categories


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, table, and legends. An unstructured abstract of ≤ 250 words is required, which should address the relevance of the subject matter, methods of the review, major findings, and conclusions.

Clinical Research

Clinical Research papers are well-designed prospective or retrospective studies describing practical results that are immediately applicable to patient care. They should include a structured abstract (≤ 250 words) consisting of the following sections: (1) Background, state the problem or purpose of the study; (2) Methods, briefly describe the study design and variables; (3) Results, describe the main findings; and (4) Conclusion, emphasize new or important aspects of the study or observations. Studies involving human subjects require approval by an Institutional Review Board or Human Subjects Review Board.

Clinical Observations

Clinical Observations are reports of clinical experience. These articles will range from clinical reports of one or several patients to reviews encompassing particular areas of clinical practice. An unstructured abstract of ≤ 250 words is required.

Techniques and Procedures

Techniques and Procedures manuscripts are “how-to-do-it” contributions by practitioners. This section should include descriptions of certain procedures, treatments, or other aspects of managing patients receiving nutrition support. An unstructured abstract of ≤ 250 words is required.

Pivotal Paper

A Pivotal Paper is a review of a previously published pivotal article. The front page of the original article will be reprinted as the second page of this article. The rest of the article should be comprised of 4 sections: Prevailing Belief System—What were the prevailing common beliefs and practices of the nutrition community at the time the original paper was published; Unique Scientific Contribution—What scientific information was imparted by this paper that changed thinking and practices; Validation—What studies have subsequently supported or contradicted the findings of this paper and how has the information held up over time; Future Considerations—Are the concepts established by this paper likely to be challenged in the future by new issues, developments, modifications, or change in thinking? An unstructured abstract of ≤ 250 words is required.

Clinical Controversy

A Clinical Controversy manuscript is a review of management in an area that is in dispute. There should be at least 2 opposing views on management of a particular clinical problem, and each view should be defensible from the literature. An unstructured abstract of ≤ 250 words is required.

Clinical Dilemma

A Clinical Dilemma paper is a discussion of a clinical problem for which there appears to be no entirely satisfactory method of management. The discussion should emphasize the nature of the dilemma, and should discuss the strengths and weaknesses of the various alternatives available for management of the clinical problem. An unstructured abstract of ≤ 250 words is required.


Editorials 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. Editorials should not contain an abstract.

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 6 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. Letters should not contain an abstract.

Manuscript Submission

New submissions should be made via the Research Exchange submission portal. You may check the status of your submission at any time by logging on to and clicking the “My Submissions” button. For technical help with the submission system, please review our FAQs or contact [email protected].

Please note that your author account will be the same for NCP as for the Journal of Parenteral and Enteral Nutrition (JPEN), since authors submitting manuscripts for publication in NCP are submitting their manuscript to the ASPEN journals’ office database, accessible to the Editors of both ASPEN 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.

When reporting studies on human subjects (whether prospective or retrospective), indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation. All authors should report any real or potential conflict of interest that may influence the readers’ perception of the work. Articles will be subject to peer review and revision and to the rules governing the Copyright Act of 1978.

Author Responsibilities

Corresponding Author

One corresponding author should be designated for each manuscript. Please provide complete contact information for the corresponding author on the title page. 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 protected].

Cover Letter

Authors must include a cover letter with their submission that includes complete contact information for one corresponding author.

Conflict of Interest

When a paper is submitted to NCP, 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 [email protected].

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.

Author Name Changes After Publication
In cases where authors wish to change their name following publication, Wiley will update and republish the paper and redeliver the updated metadata to indexing services. Our editorial and production teams will use discretion in recognizing that name changes may be of a sensitive and private nature for various reasons including (but not limited to) alignment with gender identity, or as a result of marriage, divorce, or religious conversion. Accordingly, to protect the author’s privacy, we will not publish a correction notice to the paper, and we will not notify co-authors of the change. Authors should contact the Editorial Office with their name change request.

Academic Conduct

ASPEN Policy on Academic Misconduct.

The society takes seriously its role in safeguarding the research record and ensuring the reliability of our publications. ASPEN'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 double-blind peer review processes. For more information, read the ASPEN Policy on Publishing Ethics, May 2018.

Statement of Authorship.

You must conduct a brief statement for inclusion in your manuscript that lists the role(s) of each author using criteria defined by the International Committee for Medical Journal Editors (ICMJE). Please DO NOT add this statement directly to your manuscript; upload it into the appropriate text box in Manuscript Central. The submitting author affirms that all individuals listed as authors have met the criteria of authorship. In order to meet the requirements of authorship, each author must have contributed to at least one aspect of each of the four criteria here. Please note that for Criteria 1 and 2, authors need only to meet one of the two items listed. Any individuals not meeting the criteria should be mentioned in the Acknowledgements section of the manuscript. 


Authors of Manuscript: Jane M. Doe, John Smith, and Richard E. Roe

Statement of Authorship: J. M. Doe and R. E. Roe equally contributed to the conception and design of the research; J. Smith contributed to the design of the research; J. M. Doe contributed to the acquisition and analysis of the data; J. Smith and R. E. Roe contributed to the interpretation of the data; and J. M. Doe and R. E. Roe drafted the manuscript. All authors critically revised the manuscript, agree to be fully accountable for ensuring the integrity and accuracy of the work, and read and approved the final manuscript.

Ethical Board Approval.

All studies that involve human subjects must be approved or deemed exempt by an official institutional review board (IRB), 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. If the IRB waived the requirement for ethical approval/informed consent, please provide this documentation.

Animal experiments require full compliance with local, national, ethical, and regulatory principles, and local licensing arrangements.


NCP 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 ASPEN Policy on Academic Misconduct.

How to Prepare Your Manuscript


Manuscripts should be submitted in Microsoft Word (.doc/.docx) format. Please use double spacing throughout and do not add line numbering. Standard 10- or 12-point type and spacing are preferred to proportional spacing. Use generic names of drugs, unless the specific trade name of a drug is directly relevant to the discussion; when using the trade name, please provide the manufacturer and location. Limit the use of abbreviations in the title or abstract, and in the text, citing the term in full at its first use. When reporting experiments on human subjects, indicate that the procedures followed were in accordance with the ethical standards of the responsible institutional committee on human experimentation (see below). Protect the identities of all patients. When reporting experiments on animals, indicate approval by the institution’s animal care and use committee.

Title Page

NCP uses a double-blind peer review process to reduce the likelihood of bias. Please remove your title page from the main document and upload it as a separate item at the manuscript submission page. Please also ensure that any acknowledgments or institutional affiliations mentioned in the main document do not hint at the authors’ identities.

On the title page, list each author’s full name, licensures, highest academic degrees, and affiliation. If an author’s affiliation has changed since the work was done, list the new affiliation as well. Also state the name and affiliation of any statistical reviewer consulted.

Only 1 corresponding author should be identified; complete contact information for this person should be listed on title page.


Include an abstract of no more than 250 words. Abstracts for Clinical Research submissions should be structured, consisting of the following sections: (1) Background, state the problem or purpose of the study; (2) Methods, briefly describe the study design and variables; (3) Results, describe the main findings; and (4) Conclusion, emphasize new or important aspects of the study or observations. Abstracts for review articles do not need to be explicitly structured, but should address the relevance of the subject matter, methods of the review, major findings, and conclusions.


Please number references in the order they are mentioned in the text; do not alphabetize. In text, tables, and legends, identify references with superscript Arabic numerals. In listing references, follow AMA style, abbreviating names of journals according to Index Medicus. Please list all authors up to 6 names; if there are more than 6 authors, use “et al.” following the third author.

  • Tables can be added to the end of the manuscript or submitted as a separate file(s).
  • If tables are submitted as separate files, they should be submitted as Microsoft Word (.doc/.docx) or Microsoft Excel (.xls or .xlsx) files.
  • Check that all tables are presented as true tables (i.e., can be read both across and down and are not simply lists).
  • Tables should not contain parts. For example, Table 1a, 1b should be renumbered as Table 1 and Table 2.
  • Each table column should have its own unique header.
  • Every table number must be mentioned in the text, eg, “as shown in Table 1” or, after referring to content in the table, you could add “(Table 2)”.
  • Abbreviations used in tables should be defined in a list after the table and formatted as follows (in alphabetical order): BMI, body mass index; ICU, intensive care unit…

Figures and Illustrations

  • Figures should be submitted as separate files and should not be embedded in the main document.
  • Figure captions should be listed in order at the end of the main document; figure numbers/captions should not be included on the actual figure files. Legends for Illustrations: Double-space captions and be brief (maximum 40 words). Indicate magnification and stain used for photomicrographs.
  • Please submit figures in the accepted file formats: .eps, .jpg, .tiff, .pdf, .ppt, or .xls. Note that .doc files can be submitted only if the figure was actually created in Microsoft Word. Pictures (containing no text or graphs) typically look best in .tiff, .jpg, and .pdf formats, and graphs/line art with text typically look best in .eps, .pdf, .ppt, or .xls formats.
  • Images should be submitted in high resolution. All figures need to be at least 300 dpi to ensure quality on printing. Tip: If you have a two-button mouse, simply right-click on the closed file—a drop-down list should appear. Choose the Properties option in the context menu, and then go to the Details tab to view the resolution.
  • The size of the text must be large enough to be clearly visible when the figures are resized to fit the column width (~3.5 in. wide) or page width (~7 in. wide) of the journal page.
  • Every figure number must be mentioned in the text, eg, “…as depicted in Figure 1” or, after referring to content in the figure, you could add “… for the first 7 days (Figure 2)”. Please number illustrations in order of their citation in text.
  • Abbreviations used in figures should be defined in a list after the table and formatted as follows (in alphabetical order): BMI, body mass index; ICU, intensive care unit.
  • For identifiable photographs, see instructions in Informed Consent.

Acknowledgements and Permissions

Acknowledge all material, including figures, tables, and large blocks of text that are reproduced or adapted from other sources, whether published or unpublished, and submit the original copyright owner’s written permission to reproduce or adapt the material in NCP.

Guidelines for Supplementary Material

Authors are permitted to submit supplementary tables, figures, data sets, audio files, or video files along with their manuscript into Manuscript Central. When possible, please submit as 1 combined PDF file and choose the file designation, "Supplementary File for review." These materials are intended for online-only publication and will appear in the Supporting Information section at the end of the article. They will not be published in print. Supporting information will be subject to the same standards of peer review as all material submitted for print consideration. When considering whether or not to upload supplementary material, first determine how crucial the content is to the submission or to reader comprehension and value of the material. If the material is important in the comprehension of the main text, do not upload it as supplementary content, but rather incorporate it into the main manuscript. Supplementary materials will not be copy edited or composited. It is the responsibility of the author(s) to ensure that supplementary materials are complete and free of errors. All supplementary materials must be referred to in the text where appropriate. 

All supplementary materials should be labeled using Arabic numerals as below.

Table S1, Table S2, etc.
Figure S1, Figure S2, etc.
Video S1, Video S2, etc.

English Language

Appropriate use of the English language is a requirement for publication in the Journal. Authors who have difficulty writing in English may seek assistance with grammar and style to improve the clarity of their manuscript. Many companies provide substantive editing via the Web, including American Journal ExpertsBioscience Editing SolutionsBioScience WritersBoston BioEditEditageInternational Science EditingScienceDocsSPi Professional Editing, Wiley Editing Services and Write Science Right. Please note that neither ASPEN nor NCP takes responsibility for, or endorses, these services. Their use does not guarantee acceptance of a manuscript for publication.

Informed Consent

If the manuscript reports the results of an experimental investigation of human subjects, state formally that an appropriate IRB approved the project and/or that informed consent was obtained from subjects after the nature of the procedure(s) had been explained. Protect the identities of all patients.

For all identifiable photographs, include a signed statement of consent from the patient (or, if the patient is a minor, from one or both parents or the legal guardian). Consent forms must have been approved by the IRB/ethical board and contain a statement that photographs and information about a case may be published separately or together and that the patient’s name will not be disclosed. If the IRB waived the requirement for informed consent, please provide this documentation.


Accepted manuscripts will be copyedited according to NCP style; authors may consult the 10th edition American Medical Association Manual of Style (2007) for general style guidelines.

Guidance for Journal Style and Author Resources
