Brain Tissue Oxygen Monitoring and the Intersection of Brain and Lung: A Comprehensive Review.
Traumatic brain injury is a problem that affects millions of Americans yearly and for which there is no definitive treatment that improves outcome. Continuous brain tissue oxygen (PbtO2 ) monitoring is a complement to traditional brain monitoring techniques, such as intracranial pressure and cerebral perfusion pressure. PbtO2 monitoring has not yet become a clinical standard of care, due to several unresolved questions. ⋯ Thus, continuous monitoring of PbtO2 yields important information about both the brain and the lung. The preclinical and clinical studies demonstrating these findings are discussed. In this review, we demonstrate that patient management in a PbtO2 -directed fashion is not the sole answer to the problem of treating traumatic brain injury but is an important adjunct to the armamentarium of multimodal neuromonitoring.

Soccer is the most popular sport in the world. Soccer players are at high risk for repetitive subconcussive head impact when heading the ball. Whether this leads to long-term alterations of the brain's structure associated with cognitive decline remains unknown. ⋯ Neurocognitive evaluation revealed decreased memory performance in the soccer players compared to controls. The association of cortical thinning and decreased cognitive performance, as well as exposure to repetitive subconcussive head impact, further supports the hypothesis that repetitive subconcussive head impact may play a role in early cognitive decline in soccer players. Future studies are needed to elucidate the time course of changes in cortical thickness as well as their association with impaired cognitive function and possible underlying neurodegenerative process.

Patients with traumatic brain injury (TBI) and their families rely on health care providers, particularly nurses, to provide accurate information, yet inaccurate beliefs about TBI have been found among nurses. Although prior studies have assessed nurses' beliefs about TBI recovery and rehabilitation, none have assessed specific beliefs about the nursing role to care for these patients. The purpose of this study was to investigate nurses' beliefs and learning preferences about caring for patients with moderate-to-severe TBI. ⋯ Latent class analysis was used. Findings showed that nurses had inaccurate beliefs about TBI relating to recovery and the nursing role, and had significant differences in learning preferences. These findings have implications for development of educational and training interventions specific to nurses to ensure that they have factual information about TBI and to clarify the nursing role.

Athletic neurosurgical emergencies are injuries that can lead to mortality or significant morbidity and require immediate recognition and treatment. This review article discusses the epidemiology of sports-related traumatic brain injury (TBI) with an attempt to quantify the incidence of neurosurgical emergencies in sports. Emergencies such as intracranial hemorrhage, second impact syndrome, vascular injuries, and seizures are discussed. ⋯ The incidence of sports-related TBI presenting to level I or II trauma centers in the USA is about 10 in 100,000 population per year. About 14 % of the adult sports-related TBIs and 13 % of the pediatric sports-related TBIs were moderate or severe in nature. Patients presenting with headache and neck pain should prompt further investigation for cervical spine and vascular injuries. CT angiography is becoming the modality of choice to screen for blunt cerebrovascular injuries. The treatment of these injuries remains controversial. High-quality evidence in sports-related TBI is lacking. Further research is required to help guide management of this increasingly prevalent condition. The role of prevention and education should also not be underestimated.

Predictors of Post-concussive Symptoms in Young Children: Injury versus Non-injury Related Factors.
A notable minority of children will experience persistent post-concussive symptoms (PCS) following mild traumatic brain injury (mTBI), likely maintained by a combination of injury and non-injury related factors. Adopting a prospective longitudinal design, this study aimed to investigate the relative influence of child, family, and injury factors on both acute and persistent PCS in young children. ⋯ Injury characteristics were significantly associated with PCS for 3 months following mTBI but the association weakened over time. On the other hand, pre-existing child and family factors displayed an increasingly strong association with PCS over time. Follow-up for these "at-risk" children which also addresses family stress may minimize longer-term complications. (JINS, 2016, 22, 793-803).
