Author Guidelines

Nickan Research Institute (publisher) follows the guidelines of COPE (COPE Code of Conduct and Best Practice Guidelines;



and respects the ICMJE (the International Committee of Medical Journal Editors Recommendations; https://www.icmje.org/recommendations) for Editing, Reporting, Conduct and Publication of scientific papers in the health and therapeutic journals and the updated Good Publication Practice guideline regarding authorship;


Submission of a paper to these journals means that all authors have read and agreed to all materials and content. The papers must follow the Uniform Requirements for Manuscripts Submitted to Biomedical Journals from the International Committee of Medical Journal Editors (ICMJE).

Online submission
Authors should only submit their papers directly via the online system of each journal. The editorial office does not consider submissions by intermediate companies or mediators. Manuscripts should be submitted by the corresponding author or one of the authors, however, they should not be submitted by anyone outside of the manuscript. The corresponding author is responsible to submit the copyright alongside the paper submission. Only English-written papers are accepted. The articles also should be edited by a native speaker to guarantee that, the paper was compiled by standard English grammar. We strongly suggest the authors to conduct a professional English check before paper submission to prevent hindrances with the review process. The submission also should be provided by a cover letter, which should include a statement declaring that the study complies with current ethical considerations.

 Article Types

Research (Original) Article
Research (Original) papers are a central study, which should describe noteworthy and original findings (up to ~8000 words, including tables, figures, and references). The publication of these papers is according to the novelty, and scientific reliability with regard to the analysis methods.
To prepare the original papers, the authors are required to respect the
EQUATOR Network for original studies.
Research articles must have approval from their Institutional /Hospital/University Ethics Committee for all investigations involving human or animal subjects.

Data Availability Statement

The journal’s data-sharing policy brightly incites the authors to create all datasets, making the relied conclusion of the article to be available for the readers, editors, and reviewers without unnecessary limitation.
Authors are demanded to create a Data Availability Statement in their article addressing that data is available near the corresponding author for presentation and where they can be found. In conditions, in which the research data are not publicly available or there are legal or ethical issues, the condition should be clearly mentioned in the Data Availability Statement alongside any circumstances for accessing the data. However, the judgment to publish will not be affected by whether or not; the authors share their research data.

Review Articles
A Review study (up to ~8000 words, including tables, figures, and references) is considered a summary of several articles, to cover a recent topic by authorities in its field. Review papers should comprise a serious discussion of the current studies and present a reasonable conclusion concerning previous investigations and debates.

Systematic Reviews
Systematic Review papers are literature studies dedicated to a demand which verify all high-quality published studies related to that demand. Systematic Review papers must be prepared as the following format; Introduction and Methods, then Results and Discussion. The topic should be well described. The objective of a Systematic Review study must lead to an evidence-based conclusion. The Methods section should contain a clear method of the literature search strategy. Accordingly, the data extraction procedure and grading of evidence, and finally kind of performed analysis should be described well. Meanwhile, authors are requested to conform to the
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines(www.prisma-statement.org).[T1] 

MOOSE: Meta-analyses of observational studies in epidemiology must be reported according to MOOSE guidelines


EQUATOR: To find the reporting guidelines see (www.equator-network.org).
Authors are requested to register their Systematic Reviews in the Prospero (international prospective register of systematic reviews) by the following link; https://www.crd.york.ac.uk/prospero/

Case Report
Case presentation is a case study, referred to the explanation of a patient’s history, which addresses a considerable new perception of a patient with an unusual and distinguished history. Submissions could be a single case or a case series. The uniqueness of the case may show by the presentation, the investigation, the phenotype, and case management.
To follow with the CARE guidelines (http://www.care-statement.org/) is strongly recommended. The authors should follow the CARE checklist (http://www.care-statement.org/resources/checklist) which should be submitted as a distinct file.

Commentary papers, which are published along with the article, address the important points of the article, and many expand them. Additionally, the commentaries underline/discuss the positive points of the article with some comments. Commentaries are the author’s opinions, not original materials. Commentary papers are requested by the Editors as an invitation during peer review and are related to the field of expertise of the peer reviewers.

Photo clinic
In this section, an interesting photo in the field of nephrology or endocrinology is supported by a brief description and a few references (up to five).

Epidemiology and prevention
This part is devoted mostly to epidemiology and prevention of treatment in the area of nephrology or endocrinology.

News and views
News and views are devoted mostly to recent findings of treatment in nephrology or endocrinology and renal transplantation, accompanied by the views of the authors.


This type of paper is related to an opinion or a hypothesis on a subject in the area of treatment in nephrology or endocrinology, kidney transplantation, and hemodialysis. Hypothesis articles are short manuscripts that present an original hypothesis. The article should set out a clearly identified hypothesis and be supported by adequate references.

Editorial articles addressed a specific or a recent subject, relevant to the scope of the journal. Editorials are written by an editor or other members.

Letters are papers to expand the other published articles in the journal. These papers addressed the author’s opinion on an original/review or case report. Letters could debate a recently published paper and may explore the finding of the articles and discuss the controversies along with the author’s opinion of who wrote the letter.
The editor's office then will share such letters with the authors of the primary article prior to publication to receive the author’s reply to the letter, for the next issue of the journal.

Declaration of Conflicting Interests

The Declaration of Conflicting Interests strategy denotes our official policy, which refers to a conflict of interest (COI) statement by the author.

Ethical considerations

General cautions

Every experimental or clinical study may raise controversial ethical issues (e.g., Institutional Ethical Approval for working with animal or human subjects). Thus, the Journal of Renal Endocrinology expects all authors, reviewers, and editors to consider COPE, ICMJE, and Equator Network’s reporting guidelines in medical ethics plus scientific writing.
Ethical issues (including plagiarism, misconduct, data fabrication, falsification, double publication, or redundancy) must be completely considered by the authors.
Authors reporting experimental studies on human subjects must include a statement of assurance at the end of the manuscript which addresses; (1) informed consent was obtained from each patient enrolled in the study and (2) the study protocol conforms to the ethical guidelines of the 1975 Declaration of Helsinki as reflected in a priori approval by the institution's human research committee. In studies involving animal experimentation, provide assurance that all animals received humane care according to the criteria outlined in the "
Guide for the Care and Use of Laboratory Animals" prepared by the National Academy of Sciences and published by the National Institutes of Health (NIH publication 86-23 revised 1985) and the general care of the experimental animals used for this study was conducted in compliance with the Animal Welfare Act (http://www.nap.edu/openbook.php?record_id=5140&page=114).

Statement of Ethics in original articles
The original articles published must follow the internationally accepted institutes/universities for original works and their reporting. Papers will be rejected if the journal’s office found that the study has not been provided by a proper ethical review board, and when troubles developed after publication can result to the retraction, correction, or explanation of the mooted concern conforming to COPE guidelines.

Therefore, human subject studies must be conducted upon the approval of the ethics committee along with appropriate participants’ informed consent according to the tenets of the Helsinki Declaration.

In the manuscript, the authors must address the name of the ethics committee who approved the research protocol along with the reference number.

For all investigations communicating the human body, written informed consent to participate in the research should be received from participants or their parents/legal guardians. Besides, a statement detailing this statement should be addressed in the paper.

According to the ICMJE recommendations regarding the protection of research participants, authors should avoid the spread of identifying information about participants unless strictly necessary for the submission. In this condition, the authors should certify that the study patients have offered written consent for the presentation of that information in a publication.

Likewise, the research concerning embryonic germ cells, human embryonic stem cells, cell lines, or induced pluripotent stem cells must conform with the ' Guidelines for the Conduct of Human Embryonic Stem Cell Research ' (ISSCR).

In line with the ICMJE recommendations for Clinical Trials, they should be recorded in a country that has an accessible registry recognized by the ICMJE or WHO, thereby a clinical trial number must be definitively mentioned in the paper.
Registration in the following trial registers is acceptable. Additionally, any registry that is a fundamental register of the WHO International Clinical Trials Registry Platform (ICTRP; www.who.int/ictrp/network/primary/en/index.html).


Articles reporting clinical trials should follow the guidelines of their research protocol, like the CONSORT flow chart for randomized controlled trials( https://www.equator-network.org/reporting-guidelines/consort/). Moreover, authors must use TREND for the non-randomized trial research, or other clear guidelines as mentioned on the Equator network website.

Nickan Research Institute (the publisher of this journal), adheres to the WHO definition of clinical trials.

Please also visit guidelines at http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html
STARD and TRIPOD: Investigations of diagnostic accuracy should be reported according to STARD guidelines; ( www.stard-statement.org ) and TRIPOD guidelines; (www.tripod-statement.org).

STROBE: Observational studies (cohort, case-control, or cross-sectional designs) should be reported consistent with the STROBE statement, and must be submitted with their protocols; (www.strobe-statement.org).

The clinical trials must contain the registration number mentioned in the manuscripts following the end of the abstract part and the end of the manuscripts both.

Experimental investigations on animals must follow the authors' Institutional Animal Care and Use Committee (IACUC) or an equal ethical committee (local) and should respect internationally documented rules like the ARRIVE recommendations. Hence, in the paper, the authors must address the name of the local/university ethical committee along with the reference approved number of the study protocol.

see;   https://arriveguidelines.org/about

COREQ: Qualitative research should be described according to the COREQ recommendations; (see; https://academic.oup.com/intqhc/article/19/6/349/1791966).

CHEERS: Economic evaluations must be reported according to CHEERS guidelines; (www.bmj.com/content/346/bmj.f1049).

STREGA: Genetic association studies must be reported according to STREGA recommendations; (https://pubmed.ncbi.nlm.nih.gov/19278015/).

The authors are encouraged to submit the ethical committee reference letter alongside the paper submission.

Statement of Ethics in Systematic Review Papers
The registered systematic reviews must contain a number mentioned in the manuscripts at the end of abstracts and at the end of the manuscripts both.
In systematic Review papers, authors are also encouraged to obtain institutional ethical approval from their university/hospital.

Statement of Ethics in Case Reports
The manuscript should contain a sentence delegating that, written informed consent for publication was taken and from whom
Accordingly, case reports/ case series should have approval from their Institutional /Hospital/University Ethics Committee for all investigations involving human or animal subjects.

Consent for publication for babies/children should be taken from the parents or legal guardians.
The consent statement must be available to the journal if demanded.
The authors are encouraged to submit the ethical committee reference letter alongside the paper submission.

Informed Consent
In the case of research on human subjects, informed consent and other ethical considerations should be mentioned in the "methods" section of the manuscript. The author should include a statement that informed consent was obtained for any experimentation with human subjects. As we follow the
ICMJE, please consider their guideline for more information. In cases where a study involves the use of live animals or human subjects, the author should also include a statement that all experiments were performed in compliance with the relevant laws and institutional guidelines and also state the institutional committee(s) that has approved the experiments. Moreover, the templates can be seen from WHO.
