Instructions for authors

EOM will accept the following article types:

Original investigation
This contribution should contain original controlled experimental data of basic and clinical research. The manuscript should be organized in the following sections: Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments, References, Figure Legends, Tables, Figures.

These papers represent scholarly literature review of a current topic. The authors are not obligate to contact editors prior to submission. The review process is the same as with original articles. This type of article does not have a strict limit in word and reference number although the editorial recommendation is that the article does not exceed 8000 words and 350 references.

Approach to the patient
These are review papers dealing with the clinical aspects of a disease. The authors should make a clinically oriented review of the field based on a single case presentation.

This contribution should be based on a rigorous methodological/statistical approach described in detail in the methods section applied to a relevant clinical or basic issue. This work could also be submitted to statistical revision.

Interesting and important theoretical papers dealing with cutting edge areas in clinical and basic medicine will be considered in this section. The main goal of this paper is to present a novel idea and to provide a short review of the literature supporting this idea.

Case Reports

Case reports will be considered for publication only if they present a case revealing novel and important insights into a condition’s pathogenesis, presentation, and/or management. The case report provides several important references but does not include a scholarly review of the literature. These manuscripts should be 1200 words or less, with no more than two figures and tables and 10 references.

Position and Consensus Statements related to the endocrine and metabolic health standards and healthcare practices may be submitted by professional societies, task forces, and other consortia. All such submissions will be subjected to peer review, must be modifiable in response to criticisms.

Changes to authorship

This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts.
Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.

Reporting clinical trials

Randomized controlled trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. The CONSORT checklist and template flow diagram can be found on

Registration of clinical trials

Registration in a public trials registry is a condition for publication of clinical trials in this journal in accordance with International Committee of Medical Journal Editors (ICMJE, recommendations. Trials must register at or before the onset of patient enrolment. The clinical trial registration number should be included at the end of the abstract of the article. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects of health outcomes. Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example drugs, surgical procedures, devices, behavioral treatments, dietary interventions, and process-of-care changes). Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

Informed consent and patient details

Studies on patients or volunteers require ethics committee approval and informed consent, which should be documented in the paper. Appropriate consents, permissions and releases must be obtained where an author wishes to include case details or other personal information or images of patients and any other individuals. Unless you have written permission from the patient (or, where applicable, the next of kin), the personal details of any patient included in any part of the article and in any supplementary materials (including all illustrations and videos) must be removed before submission.

Experimental Animals
A statement confirming that all animal experimentation described in the submitted manuscript was conducted in accord with accepted standards of humane animal care, should be included in the manuscript. Numbers of animals used in each group and in each experiment should be included. All research animals must be acquired and used in compliance with state and local laws and institutional regulations. Animals be maintained in accordance with the Guide for the Care and Use of Laboratory Animals [1996 (7th ed.) Washington, DC: National Research Council, National Academies Press]. The manuscript must indicate that the studies were approved by the authors’ institutional committee on animal care.
