Manuscripts are published online in PDF format as soon as they are accepted, approximately 9-10 weeks before they appear in an issue. At the same time abstracts are submitted to Medline and the paper is assigned a DOI. When citing an Immediate Publication both the journal title and the DOI must be given.

Immediate Publications have not yet been edited by our editorial staff. They are available to subscribers (and integrated into the online Journal to allow searching on authors, title, keywords and abstracts), ensuring global access to the latest research; however, they do not contain reference linking, multimedia adjuncts, online data or three-dimensional structures, and elements of the paper may differ from the final value-added article that appears in an issue of the Journal. We recommend that you refer to the final version.

Please note that in some cases authors may request that their paper is not made available through the Immediate Publications feature.
