In this edition of the International Journal of Stroke, we continue to support original research with six articles in this category. This is mainly in response to the overwhelming number of increasing submissions. This means that we are only able to accept a very low proportion of manuscripts submitted. As the journal expands in size and number of editions in future years, we will make every effort to publish as many research articles as possible as this is clearly your wish as readers.
However, as the flagship publication of the World Stroke Organization, we take seriously the responsibility to promote a global view of stroke and we continue to encourage submissions from developing countries. Panorama articles and novel original research are always of great importance in understanding the issues facing those in these regions.
Likewise, we continue to highlight protocols and high-quality reviews from cutting-edge areas of research. And of course, leading opinions are always popular with commentaries on issues of the day.
While impact factor is important, and we are extremely pleased with our steadily rising citation rate, this must always be put in the perspective of our brief as the peak global stroke journal.
Collaterals circulation is becoming an increasing focus of researchers in acute ischemic stroke, because it is emerging that they are so important in response to therapy and prognosis generally. We have two articles highlighting this theme in the current edition, the first from Chan et al. (Comprehensive stroke units: a review of comparative evidence and experience demonstrating how anterior cerebral artery co lateral circulation is associated with minimizing infarct growth) and the second leading opinion, Trials of endovascular therapies or collaterals?, is from David S. Liebeskind. He proposes that collaterals may be critical in the response to endovascular therapy, particularly at later time points. Of course, modern imaging techniques have enabled us to assess collaterals more readily and this is likely to improve further as time goes on.
We round off this edition nicely with an excellent review on comprehensive stroke units and haemorrhagic strokes in pregnancy and puerperium. We also have a fascinating panorama article about Laos. The review of the progress made by the IberoAmerican Stroke Society brings into focus the importance of international cooperation.
I hope all this keeps you well informed about what is happening around the globe in stroke!
