Traumatic brain injury (TBI) is a significant public health problem in the United States, with approximately 1.5-2 million TBIs occurring each year. However, it is believed that these figures underestimate the true toll of TBI. Soccer is the most popular sport in the world and has a following of millions in the United States. Soccer is a sport not traditionally identified as high-risk for concussions, yet several studies have shown that concussion rates in soccer are comparable to, and often exceed those of, other contact sports. As many as 22% of all soccer injuries are concussions. ⋯ In spite of such preventive measures, concussions in soccer will continue to occur. Considering the frequency of concussions in soccer, the serious sequelae of these concussions, and because almost half of concussed soccer players were noncompliant with recommended American Academy of Neurology return-to-play guidelines, further measures must be taken to protect players, in addition to understanding those criteria that result in removing an injured player from competition and the steps by which to safely return an athlete to competition after injury.

Cerebral arteriovenous malformations (AVMs) do not seem to be static congenital vascular malformations but rather are dynamically changing pathologies. In this work, we investigated the expression and possible activation of different signal transducers and activators of transcription (STAT) family members in AVM nidus. ⋯ We obtained evidence for significant overexpression and activation of both STATs 1 and 3 in cerebral AVM, thus suggesting an important role for these proteins in mediating the pathophysiology of cerebral AVM.
