abstract = {Importance: Glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) have been widely studied and show promise for clinical usefulness in suspected traumatic brain injury (TBI) and concussion. Understanding their diagnostic accuracy over time will help translate them into clinical practice. Objectives: To evaluate the temporal profiles of GFAP and UCH-L1 in a large cohort of trauma patients seen at the emergency department and to assess their diagnostic accuracy over time, both individually and in combination, for detecting mild to moderate TBI (MMTBI), traumatic intracranial lesions on head computed tomography (CT), and neurosurgical intervention. Design, Setting, and Participants: This prospective cohort study enrolled adult trauma patients seen at a level I trauma center from March 1, 2010, to March 5, 2014. All patients underwent rigorous screening to determine whether they had experienced an MMTBI (blunt head trauma with loss of consciousness, amnesia, or disorientation and a Glasgow Coma Scale score of 9-15). Of 3025 trauma patients assessed, 1030 met eligibility criteria for enrollment, and 446 declined participation. Initial blood samples were obtained in 584 patients enrolled within 4 hours of injury. Repeated blood sampling was conducted at 4, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, and 180 hours after injury. Main Outcomes and Measures: Diagnosis of MMTBI, presence of traumatic intracranial lesions on head CT scan, and neurosurgical intervention. Results: A total of 1831 blood samples were drawn from 584 patients (mean [SD] age, 40 [16] years; 62.0%[362 of 584] male) over 7 days. Both GFAP and UCH-L1 were detectible within 1 hour of injury. GFAP peaked at 20 hours after injury and slowly declined over 72 hours. UCH-L1 rose rapidly and peaked at 8 hours after injury and declined rapidly over 48 hours. Over the course of 1 week, GFAP demonstrated a diagnostic range of areas under the curve for detecting MMTBI of 0.73 (95%CI, 0.69-0.77) to 0.94 (95%CI, 0.78-1.00), and UCH-L1 demonstrated a diagnostic range of 0.30 (95%CI, 0.02-0.50) to 0.67 (95%CI, 0.53-0.81). For detecting intracranial lesions on CT, the diagnostic ranges of areas under the curve were 0.80 (95%CI, 0.67-0.92) to 0.97 (95%CI, 0.93-1.00)for GFAP and 0.31 (95%CI, 0-0.63) to 0.77 (95%CI, 0.68-0.85) for UCH-L1. For distinguishing patients with and without a neurosurgical intervention, the range for GFAP was 0.91 (95%CI, 0.79-1.00) to 1.00 (95% CI, 1.00-1.00), and the range for UCH-L1 was 0.50 (95%CI, 0-1.00) to 0.92 (95%CI, 0.83-1.00). Conclusions and Relevance: GFAP performed consistently in detecting MMTBI, CT lesions, and neurosurgical intervention across 7 days. UCH-L1 performed best in the early postinjury period. © Copyright 2016 American Medical Association. All rights reserved.},

abstract = {Purpose To investigate the epidemiology of zipline-related injuries in the United States. Basic Procedures The National Electronic Injury Surveillance System database was used to examine non-fatal zipline-related injuries treated in US emergency departments (EDs) from 1997 through 2012. Sample weights were applied to calculate national estimates. Main Findings From 1997 through 2012, an estimated 16 850 (95% CI, 13 188-20 512) zipline-related injuries were treated in US EDs. The annual injury rate per 1 million population increased by 52.3% from 7.64 (95% CI, 4.86-10.42) injuries in 2009 (the first year with a stable annual estimate) to 11.64 (95% CI, 7.83-15.45) injuries in 2012. Patients aged 0-9 years accounted for 45.0% of injuries, females made up 53.1% of injuries, and 11.7% of patients required hospitalization. Fractures accounted for the largest proportion of injuries (46.7%), and the upper extremities were the most commonly injured body region (44.1%). Falls were the most common mechanism of injury, accounting for 77.3% of injuries. Among cases where the location of the injury event was known, 30.8% of injuries occurred in a residential setting and 69.2% occurred in a public place. Principal Conclusions This study is the first to characterize the epidemiology of zipline-related injuries using a nationally representative database. The rapid increase in zipline-related injuries in recent years suggests the need for additional safety guidelines and regulations. Commercial ziplines and publicly accessible non-commercial ziplines should be subject to uniform safety standards in all states and jurisdictions across the US, and homemade ziplines should not be used. © 2015 Elsevier Inc.},

abstract = {Objective: The current study examines the demographics, injury characteristics, and outcomes associated with the presence of postconcussion amnesia in young concussion clinic patients. Design: Cross-sectional, retrospective clinical cohort. Setting: Concussion services clinic. Patients: Pediatric and adolescent concussion services program patients, presenting within 10 days postinjury, aged 10-18 years, with the goal of returning to sport (n = 245). Assessment of Risk Factors: Age, gender, race, head trauma history, injury mechanism, loss of consciousness (LOC), injuryrelated visit to an emergency department, cognitive and balance scores, symptoms, and management recommendations. Main Outcome Measures: Univariate and multivariate analyses determined adjusted odds ratios for reported presence of any postconcussion amnesia (anterograde or retrograde). Results: Factors associated with amnesia (univariate, P \< 0.10) and included in the multivariate model were race, head trauma history, mechanism of injury, LOC, injury-related visit to an emergency department, management recommendations and time of injury and initial visit symptom severity. Age and gender were also included in the model due to biological significance. Of the 245 patients, 181 had data for all model variables. Of the 181 patients, 58 reported amnesia. History of head trauma [odds ratio (OR), 2.7; 95% confidence interval (CI), 1.3-5.7]; time of injury (TOI) symptom severity \>75th percentile (OR, 2.6; 95% CI, 1.2-5.3) and LOC (OR, 2.2; 95% CI, 1.1-4.6) were found to have significant and independent relationships with amnesia in the multivariate model. Conclusions: This study illustrates that patients presenting with postconcussion amnesia are more likely to have a history of head trauma, LOC, and greater symptom severity. Future research is needed to better understand amnesia following concussion. Clinical Relevance: Amnesia presence, previous head trauma, LOC, and increased symptom severity may aid in identifying patients with a greater initial injury burden who warrant closer observation and more conservative management.

abstract = {Importance: Glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) have been widely studied and show promise for clinical usefulness in suspected traumatic brain injury (TBI) and concussion. Understanding their diagnostic accuracy over time will help translate them into clinical practice. Objectives: To evaluate the temporal profiles of GFAP and UCH-L1 in a large cohort of trauma patients seen at the emergency department and to assess their diagnostic accuracy over time, both individually and in combination, for detecting mild to moderate TBI (MMTBI), traumatic intracranial lesions on head computed tomography (CT), and neurosurgical intervention. Design, Setting, and Participants: This prospective cohort study enrolled adult trauma patients seen at a level I trauma center from March 1, 2010, to March 5, 2014. All patients underwent rigorous screening to determine whether they had experienced an MMTBI (blunt head trauma with loss of consciousness, amnesia, or disorientation and a Glasgow Coma Scale score of 9-15). Of 3025 trauma patients assessed, 1030 met eligibility criteria for enrollment, and 446 declined participation. Initial blood samples were obtained in 584 patients enrolled within 4 hours of injury. Repeated blood sampling was conducted at 4, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, and 180 hours after injury. Main Outcomes and Measures: Diagnosis of MMTBI, presence of traumatic intracranial lesions on head CT scan, and neurosurgical intervention. Results: A total of 1831 blood samples were drawn from 584 patients (mean [SD] age, 40 [16] years; 62.0%[362 of 584] male) over 7 days. Both GFAP and UCH-L1 were detectible within 1 hour of injury. GFAP peaked at 20 hours after injury and slowly declined over 72 hours. UCH-L1 rose rapidly and peaked at 8 hours after injury and declined rapidly over 48 hours. Over the course of 1 week, GFAP demonstrated a diagnostic range of areas under the curve for detecting MMTBI of 0.73 (95%CI, 0.69-0.77) to 0.94 (95%CI, 0.78-1.00), and UCH-L1 demonstrated a diagnostic range of 0.30 (95%CI, 0.02-0.50) to 0.67 (95%CI, 0.53-0.81). For detecting intracranial lesions on CT, the diagnostic ranges of areas under the curve were 0.80 (95%CI, 0.67-0.92) to 0.97 (95%CI, 0.93-1.00)for GFAP and 0.31 (95%CI, 0-0.63) to 0.77 (95%CI, 0.68-0.85) for UCH-L1. For distinguishing patients with and without a neurosurgical intervention, the range for GFAP was 0.91 (95%CI, 0.79-1.00) to 1.00 (95% CI, 1.00-1.00), and the range for UCH-L1 was 0.50 (95%CI, 0-1.00) to 0.92 (95%CI, 0.83-1.00). Conclusions and Relevance: GFAP performed consistently in detecting MMTBI, CT lesions, and neurosurgical intervention across 7 days. UCH-L1 performed best in the early postinjury period. © Copyright 2016 American Medical Association. All rights reserved.},

abstract = {Purpose To investigate the epidemiology of zipline-related injuries in the United States. Basic Procedures The National Electronic Injury Surveillance System database was used to examine non-fatal zipline-related injuries treated in US emergency departments (EDs) from 1997 through 2012. Sample weights were applied to calculate national estimates. Main Findings From 1997 through 2012, an estimated 16 850 (95% CI, 13 188-20 512) zipline-related injuries were treated in US EDs. The annual injury rate per 1 million population increased by 52.3% from 7.64 (95% CI, 4.86-10.42) injuries in 2009 (the first year with a stable annual estimate) to 11.64 (95% CI, 7.83-15.45) injuries in 2012. Patients aged 0-9 years accounted for 45.0% of injuries, females made up 53.1% of injuries, and 11.7% of patients required hospitalization. Fractures accounted for the largest proportion of injuries (46.7%), and the upper extremities were the most commonly injured body region (44.1%). Falls were the most common mechanism of injury, accounting for 77.3% of injuries. Among cases where the location of the injury event was known, 30.8% of injuries occurred in a residential setting and 69.2% occurred in a public place. Principal Conclusions This study is the first to characterize the epidemiology of zipline-related injuries using a nationally representative database. The rapid increase in zipline-related injuries in recent years suggests the need for additional safety guidelines and regulations. Commercial ziplines and publicly accessible non-commercial ziplines should be subject to uniform safety standards in all states and jurisdictions across the US, and homemade ziplines should not be used. © 2015 Elsevier Inc.},

abstract = {Objective: The current study examines the demographics, injury characteristics, and outcomes associated with the presence of postconcussion amnesia in young concussion clinic patients. Design: Cross-sectional, retrospective clinical cohort. Setting: Concussion services clinic. Patients: Pediatric and adolescent concussion services program patients, presenting within 10 days postinjury, aged 10-18 years, with the goal of returning to sport (n = 245). Assessment of Risk Factors: Age, gender, race, head trauma history, injury mechanism, loss of consciousness (LOC), injuryrelated visit to an emergency department, cognitive and balance scores, symptoms, and management recommendations. Main Outcome Measures: Univariate and multivariate analyses determined adjusted odds ratios for reported presence of any postconcussion amnesia (anterograde or retrograde). Results: Factors associated with amnesia (univariate, P \< 0.10) and included in the multivariate model were race, head trauma history, mechanism of injury, LOC, injury-related visit to an emergency department, management recommendations and time of injury and initial visit symptom severity. Age and gender were also included in the model due to biological significance. Of the 245 patients, 181 had data for all model variables. Of the 181 patients, 58 reported amnesia. History of head trauma [odds ratio (OR), 2.7; 95% confidence interval (CI), 1.3-5.7]; time of injury (TOI) symptom severity \>75th percentile (OR, 2.6; 95% CI, 1.2-5.3) and LOC (OR, 2.2; 95% CI, 1.1-4.6) were found to have significant and independent relationships with amnesia in the multivariate model. Conclusions: This study illustrates that patients presenting with postconcussion amnesia are more likely to have a history of head trauma, LOC, and greater symptom severity. Future research is needed to better understand amnesia following concussion. Clinical Relevance: Amnesia presence, previous head trauma, LOC, and increased symptom severity may aid in identifying patients with a greater initial injury burden who warrant closer observation and more conservative management.
