Author Guidelines

ARTICLE SUBMISSIONS

 The submission of articles must be done through the webpage: https://revistanutricionclinicametabolismo.org/index.php/nutricionclinicametabolismo.

When submitting the manuscript, the corresponding author must upload the following files to the OJS platform:

1. Presentation letter
2. Title page
3. Manuscript
4. Resume format (1 format per author)
5. Statement of Author's Commitment format signed by all authors
6. Checklist signed by all authors.

Likewise, the corresponding author must include the complete details of all authors (names, email address, institution, ORCID numbers) on the platform. The author will receive a confirmation email, initiating the peer-review process of the manuscript.

Not submitting one of these files may cause the rejection of your manuscript.

CRITERIA FOR INITIAL ACCEPTANCE OF ARTICLES

Without exception, manuscripts will be submitted to a complete evaluation by the Editor for its initial validation. Criteria for this first step include originality, data validation, clarity of writing, authorization by the ethics and research committee of where the research was conducted, strength of conclusions and relevance of the work in the field of clinical nutrition and metabolism.

The Journal Clinical Nutrition and Metabolism adheres to the International Committee of Medical Journal Editors (ICMJE) guidelines. Manuscripts should be prepared following the recommendations, which can be find in http://www.icmje.org/recommendations/browse/manuscript-preparation/preparing-for-submission.html

The Journal only accepts original articles, so the submission of any manuscript for consideration by the Editorial Committee indicates it is original and has not been previously published or is being evaluated for publication in other journal. Previously published works in indexed journals are not allowed. National or international clinical guidelines or recommendations published by other journals may be published after validation by the Editor and once the required permissions to published have been granted. Authors are responsible for obtaining the appropriate permissions to partially reproduce the material, wither text, tables or figures, which should be attached to the article submitted to the journal.

The Editor is responsible for the decision of accepting or rejecting manuscripts sent to the Journal for their publication.

PEER-REVIEW PROCESS

Editorial acceptance. The approval of articles is done in two steps: the first being the editorial approval of the topic and content. In a period of 30 days maximum, from the reception of the article, the corresponding author will be notified via e-mail if the submitted manuscript meets the standards and requirements detailed in the Checklist format.

Peer-review. The second step is the external and anonymous double-blind review of the manuscript. Every manuscript will be reviewed by two external peer experts to evaluate the scientific quality of the manuscript. A third opinion may be requested to review a manuscript, which will be sent to specialists in the field. With two or three opinions, the Editor will define its publication. The corresponding author will receive the final decision in a period of maximum 60 days, which could be: accepted / not accepted / resend for review / accepted with modifications.

JOURNAL SECTIONS

The journal has the following six sections: Editorials, Original Article, Case Report, Reviews (includding controversies), Protocols and Others (includes letters to the editor, news about activities of the Colombian Association of Clinical Nutrition [ACNC], interviews, etc.).

• Editorials. Both, the editorial and the guest editorials are the Editor’s responsibility and will assign any member of the Editorial Committee or guest researcher to review it. Editorials are about orientation in the domain or thematic field of the journal.
• Original Article. This section presents results of basic and clinical research. They can be clinical trials, observational studies, studies with animals, etc. in order to encourage research in basic sciences, in the field of clinical nutrition and metabolism. The Journal publishes the articles that present the results of these research in the subsection “Experimental”.
• Case Report. Description of one to four case reports of exceptional observation that represent an important contribution to the field of clinical nutrition and metabolism; each case should be accompanied by a critical review of the literature. Description of new clinical or surgical procedure related to nutrition or diet.
• Review. A review article is a selective and critical study that integrates essential information on a topic in the field of clinical nutrition and metabolism. Reviews can be narrative (literature review) or systematic (umbrella or scope). Meta-analysis will be published in this section.

1. Narrative review. These types of articles are publications that describe and discuss the state of science on a specific topic from a contextual and theoretical point of view. The goal is to publish a state of the art through updated scientific evidence about the topic.
2. Systematic reviews seek to gather all the evidence that adjusts to the pre-specified selection criteria to address a specific research question. Their goal is to minimize bias using explicit and systematic methods.
3. Scoping reviews are a type of literature review whose aim is to provide a general description of the type, scope and amount of research available about a specific topic. By “mapping” existing research, a scoping review may identify possible research gaps and future research needs and do so by using systematic and transparent methods.

Controversies. They are published in the Review section. It includes opinion, educational and review articles about basic or clinical topics relevant to clinical nutrition and that are subject of controversy in the international literature. The goal is to publish state-of-the-art articles, to clarify the different positions on the subject and give some recommendations.

• Protocols and Clinical Guidelines. Research protocols will be published with the goal to promote clinical research that has an impact and improve reproducibility, methodology, transparency, competitiveness and network collaboration.
• Others. In this section interviews, clinical practice guidelines and results of consensus or work groups of the ACNC are published. In this section it will also be published abstracts of research works of congresses.

Letters to the editor. These are objections or comments regarding articles published in the journal.
