The practice of medicine has been notably slow to adopt and integrate these new technologies, and is still largely a 'pen and paper' process.

This lack of compatibility between systems and centralized control means that the surgeon is frequently required to interact with multiple computer interfaces in order to obtain updates and exert control over the various devices at his disposal. To reduce this complexity and provide the surgeon with more complete and precise control of the operating room systems, a unified interface and communication network has been developed. In addition to improving efficiency, this network also allows the surgeon to grant remote access to consultants and observers at other institutions, enabling experts to participate in the procedure without having to travel to the site.

Research Design: Between-Groups design with two TBI groups and controls. Method and Procedures: Forty-four participants with TBI and 27 matched controls completed diffusion tensor imaging and neuropsychological measures of processing speed, attention, memory, and executive function. Multivariate analyses were conducted to examine group differences in white matter integrity (fractional anisotropy) for 11 regions of interest and cognitive performance among adult males with chronic phase, mild, moderate, or severe TBI. Correlational analyses investigated associations between white matter integrity, brain injury severity, and cognitive status. Main Outcomes and Results: Participants with moderate or severe TBI exhibited reduced white matter integrity in 8 of 11 ROIs and worse performance on most cognitive measures, relative to control participants. Persons with mild TBI did not differ from controls on white matter integrity values and differed on one measure of processing speed. Significant correlations were found between injury severity ratings and 10 ROIs, most notably between ROIs and measures of processing speed or memory. Conclusions: These findings provide nuanced information regarding white matter connectivity as it relates to neurocognitive abilities across the TBI severity spectrum.

The system also enables the surgeon to grant access and control to remote observers and participants. A test configuration has been evaluated.

Neuropsychological assessment data of 53 Operation Enduring Freedom/Operation Iraqi Freedom veterans and 48 civilians with positive history of traumatic brain injury were analyzed to assess differences with respect to cognitive performance. Retrospective analysis of data including neurocognitive test performance and self-reported symptoms of post-traumatic stress disorder and depression. Results showed worse neurocognitive performance (i.e. RBANS Total Index score) in the veteran sample relative to the civilian sample [F(1,99) = 3.92, p = .05, ƞ2 = .04], particularly on tasks measuring attentional capabilities [F(1,99) = 9.18, p = .003, ƞ2 = .09]. Additional analyses found that after controlling for post-traumatic stress disorder ...

Methods The National Acute Brain Injury Study: Hypothermia I (NABIS:H I) was a randomized multicenter clinical trial of 392 patients with severe brain injury treated using normothermia or hypothermia for 48 hours with patients reaching 33°C at 8.4 ± 3 hours after injury. The National Acute Brain Injury Study: Hypothermia II (NABIS:H II) was a randomized, multicenter clinical trial of 97 patients with severe brain injury treated with normothermia or hypothermia for 48 hours with patients reaching 35°C within 2.6 ± 1.2 hours and 33°C within 4.4 ± 1.5 hours of injury. Entry and exclusion criteria, management, and outcome measures in the 2 trials were similar. Results In NABIS:H II among the patients with evacuat...
