The study conducted by researchers in the Centre for Injury Research and Policy (CIRP) of The Research Institute at Nationwide Children's Hospital showed that these injuries accounted for 15 percent of all high school sport-related injuries.
“Twenty-nine percent of severe injuries occurred to the knee, making it the most commonly injured body site,” said the study’s co-author Christy Collins, CIRP research associate at Nationwide Children's Hospital.
“Severe injuries negatively affect athletes' health and often place an increased burden on the health care system,” said study co-author Dr Dawn Comstock, a faculty member of The Ohio State University College of Medicine.
Lung cancer and odds of survival
A lung cancer patient’s likelihood of survival can be predicted by looking at his/her quality of life before the treatment, according to a study.
Led by Dr Yingwei Qi, a team of researchers at the Mayo Clinic Rochester in Minnesota conducted research, representing 420 patients with advanced stage non-small cell lung cancer (NSCLC).
They  found that the patients’ self-assessment of their pre-treatment quality of life, could alone predict overall survival, and that for those with a low score, the risk of death was twice as high as for those with high scores.

Exposure to diesel causes cancer
American scientists have for the first time shown how exposure to diesel fumes causes cancer. Qinghua Sun, an assistant professor of Environmental Health Sciences at Ohio State University, says that diesel exhaust has the ability to induce the growth of new blood vessels that serve as a food supply for solid tumours. They found this in both healthy and diseased animals.
According to them, more new blood vessels sprouted in mice exposed to diesel exhaust than did in mice exposed to clean, filtered air.
They say this finding indicates that previous illness is not required to make humans susceptible to the damaging effects of the diesel exhaust.
