Question: What kind of shoe sponsored the practice session where Brett Banasiewicz crashed and suffered a head injury? 
Context: Traumatic brain injury (TBI), also known as intracranial injury, occurs when an external force injures the brain.  TBI can be classified based on severity, mechanism (closed or penetrating head injury), or other features (e.g., occurring in a specific location or over a widespread area).  Head injury is a broader category that may involve damage to other structures such as the scalp and skull.  TBI can result in physical, cognitive, social, emotional, and behavioral symptoms, and outcome can range from complete recovery to permanent disability or death. The Head Injury Criterion (HIC) is a measure of the likelihood of head injury arising from an impact.  The HIC can be used to assess safety related to vehicles, personal protective gear, and sport equipment. The Twyman–Stokes Teammate of the Year Award is an annual National Basketball Association (NBA) award that recognizes the league's "ideal teammate" who exemplifies "selfless play and commitment and dedication to his team."  The award is named after Jack Twyman and Maurice Stokes.  The two played together on the Rochester/Cincinnati Royals from 1955 to 1958 until Stokes' career was cut short after he suffered a head injury from a fall during a game against the Minneapolis Lakers.  Stokes would later become paralyzed due to post-traumatic encephalopathy; a brain injury that damages the motor-control center.  Twyman then became Stokes' legal guardian and advocate until Stokes died in 1970. Vans is an American manufacturer of skateboarding shoes, based in Costa Mesa, California, owned by VF Corporation.

Brett Banasiewicz (born September 26, 1994), nicknamed "Mad Dog", is an American professional BMX rider living in South Bend, Indiana.  He became a professional BMX rider at the age of 13.  In the 2010, 2011, and 2012 Brett competed in the BMX park discipline at the X Games finishing 4th, 7th and 4th respectively.  On August 23, 2012 he crashed in a practice session at the Vans LXVI BMX Invitational at Virginia Beach, Virginia suffering a head injury.  He spent 15 days in a medically induced coma whilst being treated at Sentara Princess Anne Hospital (Virginia Beach, VA). A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached.  Penetrating injury can be caused by high-velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.  Head injuries caused by penetrating trauma are serious medical emergencies and may cause permanent disability or death. Head injuries in sports of any level (junior, amateur, professional) are the most dangerous and sickening kind of injuries that can occur in sport, and are becoming more common in Australian sport.  Concussions are the most common side effect of a head injury and are defined as "temporary unconsciousness or confusion and other symptoms caused by a blow to the head."  A concussion also falls under the category of Traumatic Brain Injury (TBI).  Especially in contact sports like Australian rules football and Rugby issues with concussions are prevalent, and methods to deal with, prevent and treat concussions are continuously being updated and researched to deal with the issue.  Concussions pose a serious threat to the patients’ mental and physical health, as well as their playing career, and can result in lasting brain damage especially if left untreated.  The signs that a player may have a concussion are: loss of consciousness or non-responsiveness, balance problems (unsteadiness on feet, poor co-ordination), a dazed, blank or vacant look and/or confusion and unawareness of their surroundings.  Of course the signs are relevant only after the player experiences a blow to the head. The Center for Head Injury Services is a nonprofit organization in St. Louis, Missouri which serves people who are living with a brain injury or disability.  Among all clients placed in jobs, 89% are still in that job after 3 months.  The organization provides community-based programs including therapies, counseling, vocational and employment services, adult day services and social enterprises.  One of the organization's social enterprises, Destination Desserts, has received notoriety for its approach to employment solutions for disabled people.  The Center for Head Injury Services is a 501(c)(3) organization governed by a board of directors and led by an executive director. A head injury is any injury that results in trauma to the skull or brain.  The terms "traumatic brain injury" and "head injury" are often used interchangeably in the medical literature.  This broad classification includes neuronal injuries, hemorrhages, vascular injuries, cranial nerve injuries, and subdural hygromas, among many others.  These classifications can be further categorized as open (penetrating) or closed head injuries.  This depends on if the skull was broken or not.  Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can cause head injuries.  Many of these are minor, but some can be severe enough to require hospitalization. Patients who sustained head injury of different degree may have leukocytosis which is predictive of the severity of injury.  SeveralDFD researchers demonstrated that degree of leukocytosis correlates with severity of head trauma, and WBC of 22 correlates with severe head injury, 17- moderate and 12- mild.  Glasgow Outcome Scale also correlates with leukocytosis on admission.
