U of A research leads to enhanced CFL concussion guidelines

University football players more apt to have concussion symptoms, university hockey players more likely to suffer amnesia

2013-06-06

(Press-News.org) Research from the University of Alberta shows CFL players are more likely to value medical tests after concussions compared to university-level players. But the professional athletes were more apt to incorrectly believe it's OK to return to the sport within 24 to 48 hours if they had no symptoms. The study looked at how CFL athletes fared against their university-level peers when it came to concussion knowledge, and whether a one-hour concussion education program improved the two groups' knowledge. All of the CFL players realized the importance of seeking medical tests after a concussion vs. 67 per cent of university-level football players. On a different issue, 44 per cent of pro football players incorrectly thought it was safe to return to the sport one to two days post-concussion if they had no symptoms, while 26 per cent of their university peers believed this practice was safe. "You can still be healing from a cognitive perspective even though you feel normal," says Dhiren Naidu, lead researcher from the Faculty of Medicine & Dentistry, who worked with colleagues from the Faculty of Education on the projects. "Research shows 85 to 90 per cent of adults recover from a concussion within 10 days. Athletes usually follow a paced 'return-to-play protocol' once they are no longer displaying any concussion symptoms. Just because athletes feel better one to two days after a concussion, that doesn't mean they're healthy enough to go back and start hitting or taking a hit again." A total of 68 university athletes and 72 CFL athletes took part in this study, which involved answering a questionnaire before and after a one-hour concussion education session. Results showed most players knew how to manage concussions and what the hallmark symptoms were. And after the session, players were more apt to understand two key pieces of information: concussions can stem from blows to any part of the body, and MRI or CT imaging doesn't always detect concussions. The results demonstrated the education session improved players' knowledge. Last season the CFL implemented annual concussion education sessions for their athletes. These results confirm the effectiveness of the education sessions and outline the importance of continuing to educate athletes on the topic of concussion. Naidu, who is a physician that specializes in concussions and works in the Division of Physical Medicine and Rehabilitation with the faculty, says he was surprised that more players weren't aware of those two key facts about concussion. "These two items have been the mainstays of concussion education for years, so I was surprised more athletes weren't aware of these facts. You can get a hit anywhere on the body and get a concussion because it's about the force being transmitted to the head. You don't need a hit to the head to have a concussion." A second study led by the same team looked at concussion history and symptoms in university-level athletes. The results showed football players fared the worst when it came to experiencing a plethora of symptoms and having more than one concussion. Football players had poorer results in visual memory tests, and were more apt to report symptoms such as headaches, fatigue, drowsiness, irritability and feeling more emotional. Sixty-five per cent of hockey players, 56 per cent of football players and 50 per cent of soccer players reported experiencing concussions in the past. Hockey players were also more apt to experience amnesia post-concussion. A total of 274 male athletes took part in this second research study, including 155 football players, 67 hockey players and 52 soccer players. ### The findings from these studies were presented at a Canadian Academy of Sport Medicine meeting in April, and published online in the Clinical Journal of Sport Medicine earlier this spring. Naidu is continuing his research in this area and would like to study how athletes who have had multiple concussions fare on neuro-psychological tests five years later. He wants to know if their baseline test results change as they have more concussions. Naidu is the author of the CFL's player education session and was part of the CFL medical advisory panel that wrote the concussion guidelines that will be implemented in the league this year. He is also the team physician with the Edmonton Eskimos, the head physician for the Edmonton Oilers, and a specialist in physical medicine and rehabilitation and sport medicine.

New study shows most youth football player concussions occur during games, not practice

2013-06-06

Cincinnati, OH, June 6, 2013 -- Sports-related concussion has been referred to as an "epidemic" by the Centers for Disease Control and Prevention. Emergency department visits for concussions have increased 62% between 2001 and 2009. Despite the lack of data regarding the rates of concussions in youth football (children aged 8-12 years), concerns have been raised about the sport being dangerous for this age group. In a new study scheduled for publication in The Journal of Pediatrics, researchers analyzed the incidence rates of concussion in youth football players in this ...

Reversal cells may tip the balance between bone formation and resorption in health and disease

2013-06-06

Philadelphia, PA, June 6, 2013 – By analyzing biopsy specimens from patients with postmenopausal osteoporosis and primary hyperparathyroidism, investigators have begun to pay increasing attention to "reversal cells," which prepare for bone formation during bone remodeling. The hope is that these reversal cells will become critical therapeutic targets that may someday prevent osteoporosis and other bone disorders. This study is published in the July 2013 issue of The American Journal of Pathology. In adults, bones are maintained healthy by a constant remodeling of the ...

UI researcher and colleagues discover new species of ancient Asian lizard

2013-06-05

A new species of lizard doesn't come along every day. Even less common is a new lizard species named for a 1960s rock star. But that's exactly what University of Iowa paleoanthropologist Russell Ciochon and his co-authors reveal in an article published in the June 5 issue of the journal Proceedings of the Royal Society B. The lizard was a plant-eater, like present-day iguanas, that lived in the jungles Southeast Asia about 40 million years ago. At some 60 pounds and six feet in length, the lizard was one of the largest of its kind –- making it a veritable "king" of ...

Quality improvement educational initiative proves to be a model program for surgical residents

2013-06-05

Chicago (June 4, 2013): Researchers at Northwestern University Feinberg School of Medicine, Chicago, have developed a novel graduate medical education initiative that enables surgical residents to hone their skills in quality improvement (QI). Surgical trainees who completed the year-long educational program found the QI training to be beneficial, and more importantly, believe it put them in a position to lead QI initiatives in the future. The report appears in the June issue of the Journal of the American College of Surgeons. Today, there is little question that quality ...

Bladder cancer recurrence and mortality could decline with better treatment compliance

2013-06-05

Researchers at UCLA's Jonsson Comprehensive Cancer Center led by Dr. Karim Chamie have found that more intense surveillance and treatment of bladder cancer in the first two years after diagnosis could reduce the number of patients whose cancer returns after treatment and lower the disease's death rate. The study was published online ahead of press today in the journal Cancer. Based on the team's previous research showing underutilization of care for patients with bladder cancer, this study is the first to examine the burden of the disease on the population. To date ...

Social networks could help prevent disease outbreaks in endangered chimpanzees

2013-06-05

Athens, Ga. – Many think of social networks in terms of Facebook friends and Twitter followers, but for recent University of Georgia doctoral graduate Julie Rushmore, social networks are tools in the fight against infectious diseases. Rushmore, who completed her doctorate in the Odum School of Ecology in May, analyzed the social networks of wild chimpanzees to determine which individuals were most likely to contract and spread pathogens. Her findings, published in the Journal of Animal Ecology on June 5, could help wildlife managers target their efforts to prevent outbreaks ...

Scientists map the wiring of the biological clock

2013-06-05

The World Health Organization lists shift work as a potential carcinogen, says Erik Herzog, PhD, Professor of Biology in Arts & Sciences at Washington University in St. Louis. And that's just one example among many of the troubles we cause ourselves when we override the biological clocks in our brains and pay attention instead to the mechanical clocks on our wrists. In the June 5 issue of Neuron, Herzog and his colleagues report the discovery of a crucial part of the biological clock: the wiring that sets its accuracy to within a few minutes out of the 1440 minutes per ...

Study expands concerns about anesthesia's impact on the brain

2013-06-05

CINCINNATI – As pediatric specialists become increasingly aware that surgical anesthesia may have lasting effects on the developing brains of young children, new research suggests the threat may also apply to adult brains. Researchers from Cincinnati Children's Hospital Medical Center report June 5 the Annals of Neurology that testing in laboratory mice shows anesthesia's neurotoxic effects depend on the age of brain neurons – not the age of the animal undergoing anesthesia, as once thought. Although more research is needed to confirm the study's relevance to humans, ...

Targeting an aspect of Down syndrome

2013-06-05

ANN ARBOR—University of Michigan researchers have determined how a gene that is known to be defective in Down syndrome is regulated and how its dysregulation may lead to neurological defects, providing insights into potential therapeutic approaches to an aspect of the syndrome. Normally, nerve cells called neurons undergo an intense period of extending and branching of neuronal protrusions around the time of birth. During this period, the neurons produce the proteins of the gene called Down syndrome cell-adhesion molecule, or Dscam, at high levels. After this phase, ...

Young star suggests our sun was a feisty toddler

2013-06-05

If you had a time machine that could take you anywhere in the past, what time would you choose? Most people would probably pick the era of the dinosaurs in hopes of spotting a T. rex. But many astronomers would choose the period, four and a half billion years ago, that our solar system formed. In lieu of a working time machine, we learn about the birth of our Sun and its planets by studying young stars in our galaxy. New work suggests that our Sun was both active and "feisty" in its infancy, growing in fits and starts while burping out bursts of X-rays. "By studying ...
