Diabetologia publishes reports of clinical and experimental work on all aspects of diabetes research and related subjects provided they have scientific merit and present important facts or new data. Invited Reviews are also published. Rapid communications of results with immediate interest may also be considered for expedited publication. Mere confirmation of known facts will be accepted only in exceptional cases; the same applies to reports of experiments and observations having no positive outcome. The Editor in Chief will be pleased to consider for publication papers read at meetings of the European Association for the Study of Diabetes provided that they meet the above requirements. Letters to the Editor and Workshop reports are also welcome. It should be noted that there are no page charges with the exception of Workshop reports.
