At-home, daily application of light therapy via light-emitting diodes (LEDs) placed on the forehead and scalp led to improvements in cognitive function and post-traumatic stress disorder in patients with a traumatic brain injury (TBI), according to a groundbreaking study published in Photomedicine and Laser Surgery, a peer-reviewed journal published by Mary Ann Liebert, Inc.

In a study that included more than 120,000 adults who were treated for physical trauma, 16 percent of these patients died within 3 years of their injury, compared to an expected population mortality rate of about 6 percent, according to a study in the March 9 issue of JAMA. The researchers also found that trauma patients who were discharged to a skilled nursing facility had a significantly increased risk of death compared with patients discharged home without assistance.
The risk and nature of injury in the sport of boxing has generated a great deal of controversy in the medical community, especially in relation to youth boxing. A new study, conducted by researchers in the Center for Injury Research and Policy of The Research Institute at Nationwide Children’s Hospital, examined boxing injuries among participants 6 years of age and older from 1990 to 2008. Included in this report is a video summary of the study results with the lead researcher.
Using a sophisticated imaging test to probe for higher-level cognitive functioning in severely brain-injured patients provides a window into consciousness; but the view it presents is one that is blurred in fascinating ways, say researchers at Weill Cornell Medical College in the Feb. 25 online edition of the journal Brain.
High-quality hospitals deliver lower-cost care to trauma patients, according to a study published in the Annals of Surgery. The study found high-quality hospitals have death rates that are 34 percent lower, while spending nearly 22 percent less on trauma patient care than average-quality hospitals, suggesting high quality can coexist with lower cost. The reason is not clear, though.
After a spinal cord injury a number of factors impede the regeneration of nerve cells. Two of the most important of these factors are the destabilization of the cytoskeleton and the development of scar tissue. While the former prevents regrowth of cells, the latter creates a barrier for severed nerve cells. Scientists of the Max Planck Institute of Neurobiology in Martinsried and their colleagues from the Kennedy Krieger Institute and University of Miami in the United States, and the University of Utrecht in the Netherlands, have now shown that the cancer drug Taxol reduces both regeneration obstacles.
People diagnosed as psychopathic have difficulty showing empathy, just like patients who have suffered frontal head injury. This has been shown in a new study from the University of Haifa. “Our findings show that people who have psychopathic symptoms behave as though they are suffering frontal brain damage,” said Dr. Simone Shamay-Tsoory, who conducted the study.
Severely injured patients transported by helicopter from the scene of an accident are more likely to survive than patients brought to trauma centers by ground ambulance, according to a new study published in The Journal of Trauma: Injury, Infection, and Critical Care. The study is the first to examine the role of helicopter transport on a national level and includes the largest number of helicopter-transport patients in a single analysis.
