These short, narrowly focused articles of contemporary interest are usually commissioned by the journal. They are not minireviews. A Comment covers an aspect of an issue that is relevant to the journal's scope. Examples of this could be a discussion of the impact of new technology on research and treatment, or a discussion of changes in peer review or grant application procedures and their effect on research.
Announcement: COVID-19 and impact on peer review
As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.
