Author Information

Manuscript Formatting
Manuscript formats must be in accordance with the ICMJE-Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (updated in December 2015). Manuscripts that do not follow the instructions of Worldwide Medicine will be returned to the authors for correction without further review. Therefore, the authors must carefully review the format of the journal to avoid loss of time and work.
The Editors of Worldwide Medicine hold the right to make all the necessary changes to the language and style of the original manuscript in order to adhere to the uniform standards of the journal.

General Format
The manuscript files should be written in English in understandable style and checked for correct spelling and grammar. Authors whose first language is not English are strongly advised to have their manuscript edited by a language professional or native English speaker before the submission.
The manuscript should be typed in a Microsoft Word file, single-column format, 1.5 spaced with 2 cm margins on each side, and 8-point type in Helvetica font.
All abbreviations in the text must be defined the first time they are used (both in the abstract and the main text), and the abbreviations should be displayed in parentheses after the definition. Abbreviations should be limited to those defined in the AMA Manual of Style, current edition. Authors should avoid abbreviations in the title and abstract.
The manuscript files should not contain any information about the authors and affiliation. This is important because all manuscripts are sent for blind peer review. Author contributions, conflict of interest and funding sources must be stated at the end of the manuscript before references.
