Serial Plasma DNA Levels as Predictors of Outcome in Acute Traumatic Brain Injury.
Increased plasma deoxyribonucleic acid (DNA) levels may be associated with disease severity after acute traumatic brain injury (TBI). This study posits that increased plasma DNA levels in acute TBI are predictive of outcome. Both serial plasma nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) levels were examined in 88 consecutive patients with acute TBI and 66 control subjects. ⋯ Its levels on presentation were independently associated with outcome and higher levels (cutoff value >72.95 ng/mL) were associated with poorer outcomes. These findings suggest plasma nDNA levels reflect the severity of cerebral damage and can be considered a neuropathologic marker of patients with acute TBI. Further studies with bigger patient populations are warranted for better unbiased comparison.

Long term trends and patterns of fatal traumatic brain injuries in the pediatric and adolescent population of Austria in 1980-2012: analysis of 33 years.
Traumatic brain injuries (TBIs) are of special concern in the pediatric and adolescent population because of high incidence, mortality, and potential years of life lost (PYLL). Knowledge on causes and mortality trends is essential for effective prevention. The aim of this study was to analyze the long-term trends and causes of TBI-related mortality between 1980 and 2012 in the pediatric and adolescent populations of Austria. ⋯ In the studied period, 295,793 PYLL could be attributed to TBIs. Measures to prevent traffic accidents contributed significantly to the decrease of mortality and PYLL, especially in 15- to 19-year-old men. Causes and trends of TBI-related mortality exhibit age-group-specific patterns, and this knowledge could contribute to planning further preventive action to reduce TBI fatalities in the studied population.

Traumatic brain injury (TBI) is a significant public health concern. On average, 1.7 million persons sustain a TBI annually, and about 5.3 million Americans are living with a TBI-related disability. As the leading cause of death and disability in persons under 45 years old, there is a need for developing evidence-based interventions to reduce morbidity from this injury. ⋯ The cascade of molecular and cellular changes after TBI involves plasticity in many different neurochemical systems, which represent putative targets for neurotherapeutic interventions. Accordingly, a successful TBI treatment may have to simultaneously attenuate many injury factors. The purpose of this review is to highlight four promising nutritional intervention options that have been identified-omega-3, zinc, vitamin D, and glutamine-and to provide an up-to-date summary regarding their apparent efficacy for affecting TBI.

Significant improvements on cognitive performance post- transcranial, red/near-infrared LED treatments in chronic, mild TBI: Open-protocol study.
This pilot, open-protocol study examined whether scalp application of red and near-infrared (NIR) light-emitting diodes (LED) could improve cognition in patients with chronic, mild traumatic brain injury (mTBI). Application of red/NIR light improves mitochondrial function (especially in hypoxic/compromised cells) promoting increased adenosine triphosphate (ATP) important for cellular metabolism. Nitric oxide is released locally, increasing regional cerebral blood flow. ⋯ Participants reported improved sleep, and fewer post-traumatic stress disorder (PTSD) symptoms, if present. Participants and family reported better ability to perform social, interpersonal, and occupational functions. These open-protocol data suggest that placebo-controlled studies are warranted.

Serum Biomarkers Predict Acute Symptom Burden in Children after Concussion: A Preliminary Study.
Pediatric emergency department (ED) visits for concussion have nearly tripled in the past decade. Despite this, there are limited bedside tools available to objectively diagnose injury and prognosticate recovery. ⋯ Initial GFAP levels were associated with initial and follow-up symptom burden up to 1 month after injury, whereas follow-up GFAP levels did not correlate with symptom burden. These preliminary data suggest that GFAP may offer an objective measure of injury and recovery after pediatric concussion, potentially offering clinicians a new tool in the management of this common injury.
