- Brief Report: A short and/or rapid announcement of research results. Brief Reports should contain 1000 - 2000 words with a structured/nonstructured abstract of 200 words maximum. Short reports should comprise sections of Background, Objectives (optional), Methods, Results, and Discussion with not more than two tables or figures and up to 20 references.

- Letter: Letter to a publication, typically commenting upon a published work. Letters should contain 500 - 700 words, the maximum number of references is 10, and the maximum number of illustrations/Tables is 1. There are two types of Letters:
- Letters to the Editor about a recent journal article. Letters referring to a recent article in this journal must be received within three months of its publication. For example, a letter referring to an article published in the January issue must be submitted online no later than March 31st. Letters submitted after the allowed time will not be considered.
- Letters to the Editor NOT referring to a recent journal article. Original research that is of interest but does not fulfill all the requirements for publication as a full-length manuscript can be submitted as a letter to the editor. The letter must have a title and a maximum of three authors.
- Rapid Communication: Fast-breaking research update or other news item. Rapid communication required a structured abstract and manuscript body that included Background, Objectives, Materials/Patients and Methods, Results, and Discussion. Rapid communications should contain 1000-1500 words, the maximum number of references is 30, and the maximum Number of Figures/Tables is 3.
- Original/Research Article Article reporting on primary research (The related value "review-article" describes a literature review, research summary, or state-of-the-art article.) The content of the paper must justify its length. For reports of original investigative work, traditional division into sections is required: Title, Keywords, Addresses and which author address for correspondence, Structured/nonstructured Abstract, Background, Objectives (optional), Methods, Results, Discussion, References and Acknowledgements, Legends for display items (Figures and Tables). Research articles should contain 2500 - 3500 words, the maximum number of references is 55, and the maximum number of illustrations/Tables is 5.
- Review Article: Review or state-of-the-art summary article (The related value "research-article" describes original research.) Review Articles should contain 3500 - 4000 words, the maximum number of references is 80, and the maximum number of illustrations/Tables is 5.
- Methods Article: Study protocol articles can be used for proposed or ongoing prospective clinical research and should provide a detailed account of the study's hypothesis, rationale, and methodology. Methods articles can be used for proposed or ongoing prospective clinical research and should provide a detailed account of the study's hypothesis, rationale, and methodology. Protocols of randomized controlled trials should follow the CONSORT guidelines and must have a trial registration number. A study protocol should contain 2000 - 3000 words with a structured abstract of 300 words maximum. Study protocols should comprise sections of Background, Methods/Design, and Discussion in the abstract and full-text with not more than three tables or figures and up to 25 references. Please do not use abbreviations or references in the abstract. Trial Registration: if your $singular is a protocol of a controlled health care intervention, please list the trial registry, along with the unique identifying number, e.g., Trial registration: Current Controlled Trials ISRCTN73824458. Please note that there should be no space between the letters and numbers of your trial registration number. We recommend manuscripts that report randomized controlled trials follow the CONSORT extension for abstracts.
- Corrections: A modification or correction of previously published material, sometimes called "errata".
