Original Article

Abstract: The abstract is written after the title in the manuscript file. The abstract should be concise and not exceed 250 words. Authors should mention the techniques used without going into methodological details and should summarize the results. The abstract should be structured into five mandatory sections and one optional section: Introduction, Objective, Methods, Results (most relevant), and Conclusions. Avoid specialized abbreviations.

Introduction: When writing the Introduction, do so with non-expert readers in mind. Include a brief review of key literature and epidemiology. If there are relevant controversies or disagreements in the field, they should be mentioned in a way that a non-expert reader can understand. The Introduction should conclude with a brief statement of the general objective of the research (this should match the objective stated in the abstract).

Methods: This section should provide details on how the research was conducted with sufficient detail for reproducibility, including all appendices, protocols, instruments, and algorithms. Describe the validity and reliability of each instrument according to the type of research. Ethical considerations of the research should also be included.

Results: The Results section should provide details of all experiments required to support the paper's conclusions. There is no specific word limit for this section, but details of experiments peripheral to the central idea of the article should not be included. The section can be divided into subsections, each with a concise subheading. The section should be written with the latest available data sets. Data files, including raw data, should be presented as supplementary material or in a repository.

Discussion: The Discussion should detail the main conclusions of the work, along with an explanation or speculation about their significance, in the theoretical and background context on which the study was based. How do they affect the conclusions of existing assumptions and models in the field? How can future research build on these observations? What are the key experiments that need to be done? The discussion should be concise and well-argued.

References: Should be limited to those necessary. Enfermería Investiga does not restrict the number of references; however, a minimum of 30 per manuscript is suggested. All available works can be cited in the reference list. Acceptable sources include:

• Published or accepted manuscripts
• Manuscripts on preprint servers, if the manuscript is submitted to a journal and also available to the public as a preprint

Do not cite the following sources in the reference list:

• Unpublished work, including manuscripts that have been submitted but not yet accepted (e.g., "unpublished," "data not shown"). Instead, include these data as supplementary material or deposit them in a publicly accessible database.
• Personal communications (these should be supported by a letter from the relevant authors but not included in the reference list)

Review Article

Review articles are received by the journal and are generally solicited by the Editor-in-Chief; authors wishing to submit a review article are invited to contact the Editor-in-Chief before submission to assess the relevance and priority of the proposed topic. Review articles should focus on recent scientific or clinical advances in a broad area of interest in the health field. This type of article should be concise and include appropriate references to the literature. All review articles solicited by the editors are rigorously reviewed before a final publication decision. Authors should be experienced researchers in the discussed topic and are encouraged to review “The Ten Simple Rules for Writing a Literature Review” when writing the literature review manuscript.

Abstract: Should be succinct and not exceed 200 words. Authors should express the main idea and a concise argument position in one or two paragraphs. Avoid specialist abbreviations.

Introduction: The context of the article is set in the Introduction, logically presenting the viewpoint. Historical background should be thoroughly reviewed to explain key terms and concepts.

Development (may be structured into subsections): Should be succinct, well-focused, and engaging to interest a broad audience. Should not exceed 4000 words and should include a summary of the existing literature that places the topic in a broader context while focusing on the future: Where is the field heading? What developments are expected? It is particularly important to highlight new advances, open questions, and ongoing controversies or paradoxes, explaining how these are especially valued by a general audience. Use of color tables and figures to summarize critical points is recommended.

References: Should be limited to those necessary with a minimum of 30 references. Enfermería Investiga does not restrict the number of references; however, it is suggested not to exceed 100 for manuscripts.

Case Reports

Enfermería Investiga publishes original and interesting case reports that significantly contribute to medical knowledge. Manuscripts must meet one of the following criteria:

• Unusual or unreported side effect or adverse drug interaction.
• Unexpected or unusual presentation of a disease.
• New association or variation in disease processes.
• Presentation, diagnosis, or treatment of an emerging disease.
• Unexpected association between symptoms and disease.
• Unexpected event in the course of observing or treating a patient.

Case reports should include an up-to-date review of all previous cases in the field. Authors must obtain written and signed consent to publish patient information or from their guardians before submission. Authors will be asked to confirm informed consent as part of the submission process, and the manuscript must include a statement to this effect in a 'Consent' section, as follows: "Written informed consent was obtained from the patient for the publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal."

See “CARE guidelines” for writing the case report manuscript.

Abstract: In a case report, the structured abstract should include the following sections: Case Description; Clinical Outcomes; Treatment and Results; and Clinical Relevance.

Introduction: Should place the manuscript in a broader context. When writing the Introduction, consider non-expert readers. Include a brief review of relevant literature and epidemiology. The introduction should conclude with a brief statement of the general purpose of the case presentation and a comment on whether this objective was achieved.

Case Description: Begins with the patient's details (e.g., age, sex), followed by a chronological description of relevant aspects of the examination, diagnosis, treatment, and outcomes, ending with a brief discussion. When more than one patient is involved, describe a representative case in detail; significant differences between patients can be addressed separately. For reports involving three or fewer patients, summarize relevant abnormal findings in the text. For four or more patients, provide a table summarizing relevant abnormal findings without repeating these in the text.

Discussion: Should be concise and well-argued. Discuss the main findings, differential diagnosis, and therapeutic alternatives as appropriate. Do not include extensive literature reviews. Conclude with the value of the case presentation in its contribution to clinical practice or knowledge.

References: Should be limited to those necessary. Enfermería Investiga does not restrict the number of references; however, 30 references are suggested.

Letters to the Editor

Proposals for Letters to the Editor should not exceed 150 words, a minimum of 10 references, and no more than a total of 2 figures and/or tables (combined).
