The Sudan Journal of Medical Sciences (SJMS) is a project of the Continuous Medical Education program and an official scientific journal of the Faculty of Medicine and Health Sciences – Omdurman Islamic University. The SJMS is a regional, English-language journal with only the abstract translated and published in Arabic. The SJMS is a peer-reviewed, open-access journal publishing four issues per year since 2006. High-quality papers dealing with all aspects of medical sciences are welcomed. The main interest of the journal lies in articles that can improve clinical care or guide further research in Sudan and help in fighting and solving the health challenges that face Sudan and the regional area. A manuscript will be considered only with the understanding that it is an original contribution. The scientific and ethical liability of the manuscripts belongs to the authors, and the copyright of the manuscripts belongs to the SJMS.
The SJMS endorses the World Association of Medical Editors (WAME) Policy Statement on Geopolitical Intrusion on Editorial Decisions and the International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals. It adheres to the principles of the Committee on Publication Ethics (COPE). The SJMS also endorses the Editorial Policy Statements approved by the Council of Science Editors Board of Directors at www.councilscienceeditors.org.

Editorial policy: All manuscripts submitted for publication must be accompanied by the Copyright Transfer Form. Once this form, signed by all the authors, has been submitted, it is understood that neither the manuscript nor the data it contains have been submitted elsewhere or previously published and authors declare the statement of scientific contributions and responsibilities of all authors. The secondary publication can be done if the article meets the criteria of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals at www.icmje.org/.
Information regarding reviewers will not be revealed. SJMS follows a double-blind peer-review system. Changing the authors' names, adding or deleting them is the responsibility of the corresponding author in agreement with the editorial office.
The journal does not charge for the submission or processing of articles, however, for hard copies, a fee shall be payable by the author.All published manuscripts belong to the Sudan Journal of Medical Sciences (SJMS) and are prohibited from being published elsewhere without written permission.
General information: The journal focuses on clinical research, case reports, reviews, letter to the editor, short communications, and editorials. All accepted manuscripts are requested to be proofread by the corresponding author. Researchers from Sudan and throughout the Middle East and Africa region can submit a manuscript if it falls within the scope of the journal.Submissions can be made through the online manuscript submission system, Authors, reviewers, and editors can correspond directly with each other through this system.
Peer-review process: The manuscript is assigned to the Editor-in-Chief, who reviews the manuscript and makes an initial decision based on the manuscript quality and editorial priorities. Manuscripts that pass initial evaluation are sent for peer-review process, and the Editor-in-Chief assigns an Associate Editor. The Associate Editor sends the manuscript to two reviewers (internal and/or external reviewers). Manuscripts will be reviewed by experts in the corresponding field of the manuscript. The reviewers must review the manuscript within 30 days. The Associate Editor recommends a decision based on the reviewers’ recommendations and returns the manuscript to the Editor-in-Chief. The Editor-in-Chief makes a final decision based on editorial priorities, manuscript quality, and reviewer recommendations. If there are any conflicting recommendations from reviewers, the Editor-in-Chief can assign a new reviewer. Information reading reviewer will not be revealed, it is a double-blind process. According to the reviewer's opinion, the accepted manuscript may be sent back to the author to adjust some details. The author should upload the revised files with a reply to each query of the reviewer. The author's revisions should be completed within 10 days after the request. If it is not received by the due date, there may be delays or rejection. The revision period can be extended after the submission of a request. The author may request another reviewer's opinion, and the editorial board has the right to approve or reject it. The Editorial Board has the full final decision on approval and rejection and might request further corrections if required. Statistical editing is also performed if needed by a biostatistician. The Editor-in-Chief, Associate Editors, biostatistics expert, and English language consultant may make minor corrections to accepted manuscripts that do not change the main text of the paper.

The Editorial Policies and General Guidelines for manuscript preparation specified below are based on the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations)” by the International Committee of Medical Journal Editors (2013, archived at http://www.icmje.org/). The format of SJMS complies with the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals,” as published by the International Committee of Medical Journal Editors in Vancouver, British Columbia in 1979 (the widely accepted “Vancouver style“), as described in the Annals of Internal Medicine (1982,96 [pt 1] 114–29) for guidance. Manuscripts, including tables, references, and figure legends, must be typewritten, double spaced, on 8 ½ x 11 inch (21.5 x 28 cm) on A4-size paper, with margins of at least one inch (2.5 cm). Times New Roman is the preferred font type with font size 12. Pages should be numbered consecutively, beginning with the title page, and continuing through the last page of typewritten material. All numbers should be written in Arabic numerals throughout the manuscripts and must be written in good English.
Our preferred file format is DOCX or DOC. A single PDF file containing all materials in the manuscript including figures and figure legends should also be provided. Abbreviations should be avoided as much as possible. When used, the full expression of the abbreviations following the abbreviated word in parentheses should be given at the first use. Common abbreviations, however, may be used, such as DNA. Abbreviation can be used if it is listed as a MeSH subject heading. Authors should conform to the most recent edition of the American Medical Association Manual of Style.
The sequence of the files should be as follows: cover letter (a must), title page file, manuscript (abstract and keywords, introduction, materials and methods, results, discussion, references, tables, and figures, other submission elements). Each section title should begin on a new page.
Cover letter: The covering letter must be addressed to the Sudan Journal of Medical Sciences (SJMS) demonstrating that the submitted work is original, important, not under consideration for publication elsewhere, transfer of copyrights to the journal signed by all the authors. The cover letter should include (1) statements about manuscript type, (2) single-journal submission affirmation, (3) conflict of interest statement, (4) sources of outside funding, (5) equipment (if applicable), and (6) approval of language for articles in English and approval of statistical analysis for original research articles.
Title page: The title page must contain: (1) the title of the article, (2) the correct names, official academic and/or clinical title, and email address of each author and the name and address of the institution(s), (3) the name and address of author to whom correspondence should be sent and his phone number, (4) any disclaimers (an example of a disclaimer is an author's statement that the views expressed in the submitted article are their own and not an official position of the institution or funder), (5) the clinical trial registration number, if applicable, and finally, (6) Each author's contributions should be stated as follows: (a) study concept and design or acquisition, analysis, or interpretation of data, (b) drafting the article or revising it critically for important intellectual content, (c) final approval of the version to be published, and (d) agreement to be Accountable for the Accuracy and Integrity of all aspects of the work.
Abstract: An abstract of no more than 250 words should be submitted. It should be structured into the following four subsections: Background, Methods, Results, and Conclusions.
Keywords: 5–10 keywords may be provided.
Materials and Methods: Authors should describe the objective of the study and hypothesis appropriately in the methodology section. The primary/secondary endpoints are predetermined sensibly according to the objective of the study.
Results: In the results sections, describe the statistical tests used in the study in detail so that the readers can get the same results if the original data are available. The name and version of the statistical package should be provided. The characteristics of measured variables should determine the use of a parametric or nonparametric statistical method. For an analysis of a continuous variable, the normality of data should be examined. The “P” value defined as the limit of significance along with appropriate indicators of measurement error and uncertainty (confidence interval, etc.) should be specified. Statistical terminology (random, significant, correlation, etc.) should not be used in non-statistical contexts. Designate the name and result of the method to test normality. When analyzing a categorical variable, if the number of events and samples is small, the exact test or asymptotic method with appropriate adjustments should be used. The standard chi-squared test or difference-in-proportions test may be performed only when the sample size and number of events are sufficiently large. A prior sample size calculation should be described in detail. The sample size calculation must aim at preventing false-negative results pertaining to the primary, instead of secondary, endpoint. Usually, the mean difference and standard deviation (SD) are typical parameters in estimating the effect size. The power must be equal to or greater than 80 percent. In the case of multiple comparisons, an adjusted level of significance is acceptable.
Discussion: The conclusion should be included in the discussion section.
References: References are to be listed, double-spaced, in consecutive numerical order according to the order of citation in the manuscript. Once a reference is cited, all subsequent citations should be to the original number. All references must be cited in the text or tables and appear as superscript numbers between two square brackets. Unpublished data and personal communications will not be accepted as references. References (Vancouver style) to journal articles should follow this order: (1) authors, (2) title, (3) journal name (as abbreviated in Index Medicus), (4) year of publication, (5) volume and issue number, and (6) inclusive page numbers. References to books should include (1) authors, (2) chapter title (if any), (3) editor's names (if any), (4) title of the book, (5) city of publication, (6) publisher name, and (7) year of publication. Volume and edition numbers and specific page numbers should be included when appropriate. The authors are responsible for the correct textual citation. The use of citation managers is encouraged.
Tables: Each table should be typed double-spaced, including all headings. Verify tabular statistics to make sure they match the data cited in the text. Tables should be placed after the Results section. Tables capture information concisely and display it efficiently; they also provide information at any desired level of detail and precision. Including data in tables rather than text frequently makes it possible to reduce the length of the text. Number tables consecutively in the order of their first citation in the text and supply a title for each. Titles in tables should be short but self-explanatory, containing information that allows readers to understand the table's content without having to go back to the text. Be sure that each table is cited in the text. Give each column a short or an abbreviated heading. Authors should place explanatory matter in footnotes, not in the heading. Explain all nonstandard abbreviations in footnotes and use symbols to explain information if needed. If you use data from another published or unpublished source, obtain permission and acknowledge that source fully. Additional tables containing backup data too extensive to publish in print may be appropriate for publication in the electronic version of the journal, deposited with an archival service, or made available to readers directly by the authors. An appropriate statement should be added to the text to inform readers that this additional information is available and where it is located.
Figures: The captions for the figures must be typed, double-spaced, and must not appear on the figures. For X-ray films, scans, and other diagnostic images, as well as pictures of pathology specimens or photomicrographs, high-resolution photographic image files should be provided. Photomicrographs should have internal scale markers. Symbols, arrows, or letters used in photomicrographs should contrast with the background. Explain the internal scale and identify the method of staining in photomicrographs. Figures should be numbered consecutively according to the order in which they have been cited in the text. If a figure has been published previously, acknowledge the original source and submit written permission from the copyright holder to reproduce it. Permission is required irrespective of authorship or publisher except for documents in the public domain. In the manuscript, the legends for illustrations should be on a separate page, with Arabic numerals corresponding to the illustrations. When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one clearly in the legend and send it in separate files.
Systemic review: Systematic reviews, as the name implies, typically involve a detailed and comprehensive plan and search strategy derived a priori, with the goal of reducing bias by identifying, appraising, and synthesizing all relevant studies on a particular topic. Systematic Reviews should address a specific question or issue that is relevant for clinical practice and provide an evidence-based, balanced, patient-oriented review on a focused topic.

Case report: Please ensure that all patient data have been de-identified and that necessary approval has been obtained, if necessary, from an ethics commission or an institutional review board. These guidelines are based on the CARE guidance.
Letter to the Editor: The Letters to the Editor should be short commentaries related to current developments in the medical field and their scientific and social aspects, they may be submitted to ask questions or offer further contributions in response to work that has been published in the Journal. Letters do not include a title or an abstract; they should not exceed 1,000 words and can have up to 5 references. The references in the letters should not exceed 15 words, figures, not more than two, and tables should not exceed two. The subdivisions of sections are encouraged to help orient the reader but should be general, such as “The Study” and “Conclusions.” Letters to the editor are generally updates on recent infectious disease trends and research but may also respond to recent articles published in SJMS.
