There are a plethora of medical journals, also for the diabetes indication. Only a limited number of these journals are listed in databases like PubMed. A number of other diabetes journals approach potential authors and ask for submission of manuscripts. They promise rapid publication; however, one wonders what kind of impact these journals have and how serious they are at handling the review process and so on. One wonders what the economical basis (= business model) for these journals is, the publication fee might be considerable. Apparently, some journals pretend to publish manuscripts; however, this does not happen in reality, despite the fact that the authors have paid the publication fee. In the same line of thinking, the quality of the publications in these journals is at least questionable.
