The amount of oxidative stress in patients with an isolated traumatic brain injury (ITBI) can be estimated by measuring several biochemical parameters, such as total antioxidants, lipid peroxidation, protein oxidation, and others. Unfortunately, measuring these parameters is time-consuming, impractical in a clinical setting, and may miss important factors(More)
The authors' Level I trauma center has advocated the use of ski helmets for several years and in 1998, undertook a social-marketing campaign and a helmet loaner program to increase helmet use among skiers and snowboarders. The loaner program's effect on helmet acceptance was measured by comparing helmet acceptance in participating rental stores with(More)
There are few reliable markers for assessing traumatic brain injury (TBI). Elevated levels of oxidative stress have been observed in TBI patients. We hypothesized that oxidation-reduction potential (ORP) could be a potent biomarker in TBI. Two types of ORP were measured in patient plasma samples: the static state of oxidative stress (sORP) and capacity for(More)
