Clinical TrialRobotic Assessment of Motor, Sensory, and Cognitive Function in Acute Sport-Related Concussion and Recovery.
There is a need for better tools to objectively, reliably, and precisely assess neurological function after sport-related concussion (SRC). The aim of this study was to use a robotic device (Kinesiological Instrument for Normal and Altered Reaching Movements; KINARM) to quantify neurological impairments in athletes acutely and when clinically asymptomatic post-SRC. Robotic assessments included five KINARM standard tasks that evaluate aspects of motor, sensory, and cognitive function. ⋯ We identified relationships between acute symptom severity and task performance for only two parameters, both of which evaluated attributes of motor function. Overall, the KINARM identified impairments in motor, sensory, and cognitive function in athletes with SRC; however, impairment rates were low and largely did not relate to symptom severity. More complex tasks may be necessary to identify potentially subtle neurological impairments post-SRC.

Adult Firearm-Related Traumatic Brain Injury in United States Trauma Centers.
Civilian firearm injury is an important public health concern in the United States. Gunshot wounds to the head (GSWH) remain in need of update and systematic characterization. We identify predictors of prolonged hospital length of stay (HLOS), intensive care unit length of stay (ICU LOS), medical complications, mortality, and discharge disposition from a population-based sample using the National Sample Program (NSP) of the National Trauma Data Bank (NTDB), years 2003-2012. ⋯ Our results support hypotension, injury severity, injury intent, firearm type, and U. S. geographical location as important prognostic variables in firearm-related TBI. Improved understanding of civilian GSWH is critical to promoting increased awareness of firearm injuries as a public health concern and reducing its debilitating injury burden to patients, families, and healthcare systems.

Severe Traumatic Brain Injury Induces Early Changes in the Physical Properties and Protein Composition of Intracranial Extracellular Vesicles.
Extracellular vesicles (EVs) are membranous nanostructures that can indicate undergoing processes in organs and thus help in diagnostics and prognostics. They are secreted by all cells, contained in body fluids, and able to transfer proteins, lipids and nucleic acids to distant cells. Intracranial EVs were shown to change their composition after severe traumatic brain injury (TBI) and therefore to have biomarker potential to evaluate brain events. ⋯ CSF concentrations of Arf6 and Rab7a were negatively correlated. Our data suggest that the brain response within several days after severe TBI includes shedding of EVs associated with neuroplasticity. Extended studies with a larger number of participants and CSF collected at shorter intervals are necessary to further evaluate neuroregeneration biomarker potential of Rab7a, Arf6, and Flotillin-1.

Risk of Depression after Traumatic Brain Injury in a Large National Sample.
Depression is associated with poorer recovery after traumatic brain injury (TBI), yet awareness of depression risk post-TBI among providers and patients is low. The aim of this study was to estimate risk of depression post-TBI among adults 18 years of age and older and to identify risk factors associated with developing depression post-TBI. We conducted a retrospective, matched cohort study using claims data for privately insured and Medicare Advantage enrollees in a large U. ⋯ Risk of depression increases substantially post-TBI. Groups at increased risk include those with a history of neuropsychiatric disturbances, older adults, and men. This study highlights the importance of long-term monitoring for depression post-TBI.

Longitudinal Developmental Outcomes after Traumatic Brain Injury in Young Children: Are Infants More Vulnerable Than Toddlers?
Children under 4 years of age have the highest incidence of traumatic brain injury (TBI) among the non-elderly and may be at high risk of poor developmental outcomes. We prospectively enrolled a cohort of children injured before 31 months old with TBI or orthopedic injury (OI), from 2013 to 2015 at two pediatric level 1 trauma centers to study very young children's developmental outcomes after injury. We used Ages & Stages-3 and Ages & Stages: Social-Emotional screening tools to measure children's development at pre-injury and 3 and 12 months post-injury. ⋯ Despite low developmental scores in 28% of the cohort, only 5% were receiving Early Childhood Intervention (ECI) services 12 months after injury. Early age at injury is a vulnerability factor after TBI. Young age and severe injury should prompt evaluation for ECI.
