abstract = {OBJECTIVES: To assess the role of brain networks in emotion regulation and post-traumatic complaints in the sub-acute phase after non-complicated mild traumatic brain injury (mTBI). EXPERIMENTAL DESIGN: Fifty-four patients with mTBI (34 with and 20 without complaints) and 20 healthy controls (group-matched for age, sex, education, and handedness) were included. Resting-state fMRI was performed at four weeks post-injury. Static and dynamic functional connectivity were studied within and between the default mode, executive (frontoparietal and bilateral frontal network), and salience network. The hospital anxiety and depression scale (HADS) was used to measure anxiety (HADS-A) and depression (HADS-D). PRINCIPAL OBSERVATIONS: Regarding within-network functional connectivity, none of the selected brain networks were different between groups. Regarding between-network interactions, patients with complaints exhibited lower functional connectivity between the bilateral frontal and salience network compared to patients without complaints. In the total patient group, higher HADS-D scores were related to lower functional connectivity between the bilateral frontal network and both the right frontoparietal and salience network, and to higher connectivity between the right frontoparietal and salience network. Furthermore, whereas higher HADS-D scores were associated with lower connectivity within the parietal midline areas of the bilateral frontal network, higher HADS-A scores were related to lower connectivity within medial prefrontal areas of the bilateral frontal network. CONCLUSIONS: Functional interactions of the executive and salience networks were related to emotion regulation and complaints after mTBI, with a key role for the bilateral frontal network. These findings may have implications for future studies on the effect of psychological interventions.Copyright © 2016 Wiley Periodicals, Inc.},

abstract = {CONTEXT: Younger age has been hypothesized to be a risk factor for prolonged recovery after sport-related concussion, yet few studies have directly evaluated age differences in acute recovery. OBJECTIVE: To compare clinical recovery patterns for high school and collegiate athletes. DESIGN: Prospective cohort study. SETTING: Large, multicenter prospective sample collected from 1999-2003 in a sports medicine setting. SUBJECTS: Concussed athletes (n = 621; 545 males and 76 females) and uninjured controls (n = 150) participating in high school and collegiate contact and collision sports (79% in football, 15.7% in soccer, and the remainder in lacrosse or ice hockey). MAIN OUTCOME MEASURE(S): Participants underwent evaluation of symptoms (Graded Symptom Checklist), cognition (Standardized Assessment of Concussion, paper-and-pencil neuropsychological tests), and postural stability (Balance Error Scoring System). Athletes were evaluated preinjury and followed serially at several time points after concussive injury: immediately, 3 hours postinjury, and at days 1, 2, 3, 5, 7, and 45 or 90 (with neuropsychological measures administered at baseline and 3 postinjury time points). RESULTS: Comparisons of concussed high school and collegiate athletes with uninjured controls suggested that high school athletes took 1 to 2 days longer to recover on a cognitive (Standardized Assessment of Concussion) measure. Comparisons with the control group on other measures (symptoms, balance) as well as direct comparisons between concussed high school and collegiate samples revealed no differences in the recovery courses between the high school and collegiate groups on any measure. Group-level recovery occurred at or before 7 days postinjury on all assessment metrics. CONCLUSIONS: The findings suggest no clinically significant age differences exist in recovery after sport-related concussion, and therefore, separate injury-management protocols are not needed for high school and collegiate athletes.},

abstract = {IMPORTANCE: Approximately one-third of children experiencing acute concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent postconcussion symptoms (PPCS). However, validated and pragmatic tools enabling clinicians to identify patients at risk for PPCS do not exist. OBJECTIVE: To derive and validate a clinical risk score for PPCS among children presenting to the emergency department. DESIGN, SETTING, AND PARTICIPANTS: Prospective, multicenter cohort study (Predicting and Preventing Postconcussive Problems in Pediatrics [5P]) enrolled young patients (aged 5-\<18 years) who presented within 48 hours of an acute head injury at 1 of 9 pediatric emergency departments within the Pediatric Emergency Research Canada (PERC) network from August 2013 through September 2014 (derivation cohort) and from October 2014 through June 2015 (validation cohort). Participants completed follow-up 28 days after the injury. EXPOSURES: All eligible patients had concussions consistent with the Zurich consensus diagnostic criteria. MAIN OUTCOMES AND MEASURES: The primary outcome was PPCS risk score at 28 days, which was defined as 3 or more new or worsening symptoms using the patient-reported Postconcussion Symptom Inventory compared with recalled state of being prior to the injury. RESULTS: In total, 3063 patients (median age, 12.0 years [interquartile range, 9.2-14.6 years]; 1205 [39.3%] girls) were enrolled (n=2006 in the derivation cohort; n=1057 in the validation cohort) and 2584 of whom (n=1701 [85%] in the derivation cohort; n=883 [84%] in the validation cohort) completed follow-up at 28 days after the injury. Persistent postconcussion symptoms were present in 801 patients (31.0%) (n=510 [30.0%] in the derivation cohort and n=291 [33.0%] in the validation cohort). The 12-point PPCS risk score model for the derivation cohort included the variables of female sex, age of 13 years or older, physician-diagnosed migraine history, prior concussion with symptoms lasting longer than 1 week, headache, sensitivity to noise, fatigue, answering questions slowly, and 4 or more errors on the Balance Error Scoring System tandem stance. The area under the curve was 0.71 (95% CI, 0.69-0.74) for the derivation cohort and 0.68 (95% CI, 0.65-0.72) for the validation cohort. CONCLUSIONS AND RELEVANCE: A clinical risk score developed among children presenting to the emergency department with concussion and head injury within the previous 48 hours had modest discrimination to stratify PPCS risk at 28 days. Before this score is adopted in clinical practice, further research is needed for external validation, assessment of accuracy in an office setting, and determination of clinical utility.},

abstract = {BACKGROUND: Better diagnostic and prognostic tools are needed to address issues related to early diagnosis and management of concussion across the continuum of aging but particularly in children and adolescents. The purpose of the current study was to evaluate the reliability of robotic technology (KINARM robot) assessments of reaching, position sense, bimanual motor function, visuospatial skills, attention and decision making in youth ice hockey players (ages 10-14). METHODS: Thirty-four male children attended two testing days, one week apart. On day one, each subject completed five tasks on the robot with two examiners (alternating examiner sequence); the 2(nd) examiner followed the same procedure as the 1(st) immediately afterwards. One consistent examiner tested subjects one week later. This is a test-retest reliability study. The robotic tasks characterize sensorimotor and/or cognitive performance; 63 parameters from 5 tasks are reported. Session 1 was the 1(st) time the subject performed the 5 tasks, session 2 the 2(nd) time on day 1, and session 3 one week following. RESULTS: Intra-class correlation coefficients ranged from 0.06 to 0.91 and 0.09 to 0.90 for session 1 to 2 and 2 to 3, respectively. Bland-Altman plots showed agreement in a majority of the parameters and a learning effect in 25 % and 24 % of parameters in session 1 vs 2 and 1 vs 3, respectively but none for session 2 vs 3. Of those that showed a learning effect, only 8 % of parameters in session 1 vs 2 and 10 % in session 1 vs 3 had a clinical relevance measure\>0.8. CONCLUSIONS: The relative homogeneity of the sample and the effect of learning seen in some of the task parameters appears to have negatively impacted the intra-class correlation coefficients from session 1 to 2, with less impact for 2 to 3. The Bland-Altman analysis supports good absolute reliability in healthy male children with no neurological impairment ranging in age from 10 to 14. The clinically relevant learning effect seen, in a small number of parameters could be addressed by creating a learning effect adjustment factor and/or implementing a practice session, which would eliminate the learning effect.},

abstract = {BACKGROUND: The benefit of preseason concussion education on athletes' knowledge, attitudes, and behaviors is unclear. The purpose of the study was to determine the influence of preseason concussion education on knowledge and self-reported attitudes and reporting behaviors. We hypothesized that preseason education would lead to better knowledge and self-reported attitudes and better reporting of concussion symptoms during the season. METHODS: This study involved a prospective cohort comparing the benefits of a preseason lectured-based concussion education session at one high school with a control school. Participants included males and females age 13 years to 18 years from two community high schools who were participating in higher concussion risk, fall or winter sports (football, soccer, wrestling, and basketball). The education school and control school included 234 and 262 participants, respectively. Outcomes were a preseason and postseason survey assessing knowledge and self-reported attitudes about concussions and an end-of-season questionnaire assessing concussion reporting behaviors during the season. RESULTS: Total scores on the combined (p \< 0.0001), knowledge-based (p = 0.016), and behavioral-based (p \< 0.0001) questions demonstrated statistically significant improvement in the education group. Scores peaked immediately after education but dissipated at the end of the season. There was a lower proportion in the education school (72%) compared with the control school (88%) that reported continued play despite having concussion symptoms during the season (p = 0.025). A similar proportion of athletes diagnosed with concussion during the season in the education (27%) and control schools (23%) reported returning to play before symptoms resolved (p = 0.81). CONCLUSION: These findings suggest that a didactic-based preseason concussion education likely has minimal benefits. Other factors besides knowledge are likely influencing student-athlete concussion reporting behavior. Future research focused on changing the culture of concussion reporting is needed. LEVEL OF EVIDENCE: Therapeutic study, level III.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

An observational prospective study was conducted. From 2007, the World Footballers' Union (FIFPro) and its related national footballers' unions (more than 70 countries distributed across all continents) collected descriptive data (football-related, cause, etc.) on mortality of active (during career) and recently retired (postcareer before reaching 45 years of age) professional footballers by means of several official sources. A total of 214 deaths were recorded among active and recently retired professional footballers, leading to an overall mortality rate of 0.47 per 1000 footballers per year. Of the 214 deaths, 183 were recorded among active players and 31 among recently retired players. Among the active players, 17% of the fatalities were related to football participation. Disease was the leading cause of death among professional footballers (55%), of which up to 33% accounted for suspected cardiac pathology. Accidents accounted for 25% of the overall deaths, and suicide for 11%. From 2007 to 2013, 214 deaths were recorded among active (during career) and recently retired (post career) professional footballers. Leading cause of death was disease (55%), one third of which were accounted for by suspected cardiac pathology, while accidents accounted for 25% of all deaths, and suicide for 11%. Attention to the predictive validity and application of heart-related precompetition medical assessment should be given, and mental health support should be developed and implemented both during and after a professional football career to prevent potential suicidal behaviors.},

abstract = {Context: Analysis of health care service models requires the collection and evaluation of basic practice characterization data. Practice-based research networks (PBRNs) provide a framework for gathering data useful in characterizing clinical practice. Objective: To describe preliminary secondary school setting practice data from the Athletic Training Practice-Based Research Network (AT-PBRN). Design: Descriptive study. Setting: Secondary school athletic training facilities within the AT-PBRN. Patients or Other Participants: Clinicians (n = 22) and their patients (n = 2523) from the AT-PBRN. Main Outcome Measure(s): A Web-based survey was used to obtain data on clinical practice site and clinician characteristics. Patient and practice characteristics were obtained via deidentified electronic medical record data collected between September 1, 2009, and April 1, 2011. Descriptive data regarding the clinician and CPS practice characteristics are reported as percentages and frequencies. Descriptive analysis of patient encounters and practice characteristic data was performed, with the percentages and frequencies of the type of injuries recorded at initial evaluation, type of treatment received at initial evaluation, daily treatment, and daily sign-in procedures. Results: The AT-PBRN had secondary school sites in 7 states, and most athletic trainers at those sites (78.2%) had less than 5 years of experience. The secondary school sites within the AT-PBRN documented 2523 patients treated across 3140 encounters. Patients most frequently sought care for a current injury (61.3%), followed by preventive services (24.0%), and new injuries (14.7%). The most common diagnoses were ankle sprain/strain (17.9%), hip sprain/strain (12.5%), concussion (12.0%), and knee pain (2.5%). The most frequent procedures were athletic trainer evaluation (53.9%), hot- or cold-pack application (26.0%), strapping (10.3%), and therapeutic exercise (5.7%). The median number of treatments per injury was 3 (interquartile range = 2, 4; range = 2-19). Conclusions: These preliminary data describe services provided by clinicians within the AT-PBRN and demonstrate the usefulness of the PBRN model for obtaining such data.},

DESIGN: Prospective evaluation of leisure participation at 1 year after TBI. SETTING: Level I trauma center. PARTICIPANTS: Rehabilitation inpatients (mean age, 35.3 years; 77% male; 77% white) with moderate to severe TBI (N=160). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Functional Status Examination. RESULTS: At 1 year after injury, 81% had not returned to preinjury levels of leisure participation. Activities most frequently discontinued included partying, drug and alcohol use, and various sports. The activity most often reported as new after injury was watching television. Of the small fraction who returned to preinjury levels, 70% did so within 4 months of injury. Sixty percent of those who did not return to preinjury levels were moderately to severely bothered by the changes. CONCLUSIONS: At 1 year after injury, many TBI survivors engage in a reduced number of leisure activities, which are more sedentary and less social, with a substantial fraction dissatisfied with these changes. While discontinuing some activities may be viewed as a positive change, there are few new ones to replace them.},

abstract = {In 1991, a population-based epidemiologic traumatic brain injury (TBI) study was done in urban and rural areas of Taiwan; this was 5 years before the helmet use law was passed and 8 years before the drink driving law was passed. In order to evaluate the impact of three major determinants (time, geography, and legislation) on the epidemiology of TBI, we conducted a prospective study in 2001 and used the 1991 data to examine the differences in TBI distribution in urban and rural Taiwan a decade after these laws were passed. In 2001, 5754 TBI cases were collected from the urban area of Taipei City, and 1474 TBI cases were collected from the rural area of Hualien County. The TBI incidence rate in Taipei City in 2001 was estimated to be 218/100,000 population (285/100,000 for males and 152/100,000 for females). When compared to the 1991 data, the incidence rate in 2001 had increased by 20%. The TBI incidence rate in Hualien County in 2001 was estimated to be 417/100,000 population (516/100,000 for males and 306/100,000 for females); this was a 37% increase over the 1991 data. Our study found that the distribution of causes and age distribution had shifted significantly over the 10-year period. In 2001, the age group with the highest incidence was 20-29 years, while in 1991 it had been the over 70 years age group. While traffic-related TBI had decreased, falls and assaults had increased in 2001. We also found that legislation, such as the helmet law, affects TBI distribution by decreasing the traffic-related TBI rate, decreasing the admission severity of TBI, and reducing TBI-related mortality. Finally, geography plays a crucial role in the outcome of TBI; over the 10 year period, Taipei had an increase in moderately severe outcomes, while Hualien had an increase in more severe outcomes. Comparative studies of TBI in urban and rural areas have shown that time, legislation, and geography are crucial determinants of TBI epidemiology. Although time and legal interventions seem to have more of an impact, geography does affect TBI outcomes.},

abstract = {OBJECTIVES: To assess the role of brain networks in emotion regulation and post-traumatic complaints in the sub-acute phase after non-complicated mild traumatic brain injury (mTBI). EXPERIMENTAL DESIGN: Fifty-four patients with mTBI (34 with and 20 without complaints) and 20 healthy controls (group-matched for age, sex, education, and handedness) were included. Resting-state fMRI was performed at four weeks post-injury. Static and dynamic functional connectivity were studied within and between the default mode, executive (frontoparietal and bilateral frontal network), and salience network. The hospital anxiety and depression scale (HADS) was used to measure anxiety (HADS-A) and depression (HADS-D). PRINCIPAL OBSERVATIONS: Regarding within-network functional connectivity, none of the selected brain networks were different between groups. Regarding between-network interactions, patients with complaints exhibited lower functional connectivity between the bilateral frontal and salience network compared to patients without complaints. In the total patient group, higher HADS-D scores were related to lower functional connectivity between the bilateral frontal network and both the right frontoparietal and salience network, and to higher connectivity between the right frontoparietal and salience network. Furthermore, whereas higher HADS-D scores were associated with lower connectivity within the parietal midline areas of the bilateral frontal network, higher HADS-A scores were related to lower connectivity within medial prefrontal areas of the bilateral frontal network. CONCLUSIONS: Functional interactions of the executive and salience networks were related to emotion regulation and complaints after mTBI, with a key role for the bilateral frontal network. These findings may have implications for future studies on the effect of psychological interventions.Copyright © 2016 Wiley Periodicals, Inc.},

abstract = {CONTEXT: Younger age has been hypothesized to be a risk factor for prolonged recovery after sport-related concussion, yet few studies have directly evaluated age differences in acute recovery. OBJECTIVE: To compare clinical recovery patterns for high school and collegiate athletes. DESIGN: Prospective cohort study. SETTING: Large, multicenter prospective sample collected from 1999-2003 in a sports medicine setting. SUBJECTS: Concussed athletes (n = 621; 545 males and 76 females) and uninjured controls (n = 150) participating in high school and collegiate contact and collision sports (79% in football, 15.7% in soccer, and the remainder in lacrosse or ice hockey). MAIN OUTCOME MEASURE(S): Participants underwent evaluation of symptoms (Graded Symptom Checklist), cognition (Standardized Assessment of Concussion, paper-and-pencil neuropsychological tests), and postural stability (Balance Error Scoring System). Athletes were evaluated preinjury and followed serially at several time points after concussive injury: immediately, 3 hours postinjury, and at days 1, 2, 3, 5, 7, and 45 or 90 (with neuropsychological measures administered at baseline and 3 postinjury time points). RESULTS: Comparisons of concussed high school and collegiate athletes with uninjured controls suggested that high school athletes took 1 to 2 days longer to recover on a cognitive (Standardized Assessment of Concussion) measure. Comparisons with the control group on other measures (symptoms, balance) as well as direct comparisons between concussed high school and collegiate samples revealed no differences in the recovery courses between the high school and collegiate groups on any measure. Group-level recovery occurred at or before 7 days postinjury on all assessment metrics. CONCLUSIONS: The findings suggest no clinically significant age differences exist in recovery after sport-related concussion, and therefore, separate injury-management protocols are not needed for high school and collegiate athletes.},

abstract = {IMPORTANCE: Approximately one-third of children experiencing acute concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent postconcussion symptoms (PPCS). However, validated and pragmatic tools enabling clinicians to identify patients at risk for PPCS do not exist. OBJECTIVE: To derive and validate a clinical risk score for PPCS among children presenting to the emergency department. DESIGN, SETTING, AND PARTICIPANTS: Prospective, multicenter cohort study (Predicting and Preventing Postconcussive Problems in Pediatrics [5P]) enrolled young patients (aged 5-\<18 years) who presented within 48 hours of an acute head injury at 1 of 9 pediatric emergency departments within the Pediatric Emergency Research Canada (PERC) network from August 2013 through September 2014 (derivation cohort) and from October 2014 through June 2015 (validation cohort). Participants completed follow-up 28 days after the injury. EXPOSURES: All eligible patients had concussions consistent with the Zurich consensus diagnostic criteria. MAIN OUTCOMES AND MEASURES: The primary outcome was PPCS risk score at 28 days, which was defined as 3 or more new or worsening symptoms using the patient-reported Postconcussion Symptom Inventory compared with recalled state of being prior to the injury. RESULTS: In total, 3063 patients (median age, 12.0 years [interquartile range, 9.2-14.6 years]; 1205 [39.3%] girls) were enrolled (n=2006 in the derivation cohort; n=1057 in the validation cohort) and 2584 of whom (n=1701 [85%] in the derivation cohort; n=883 [84%] in the validation cohort) completed follow-up at 28 days after the injury. Persistent postconcussion symptoms were present in 801 patients (31.0%) (n=510 [30.0%] in the derivation cohort and n=291 [33.0%] in the validation cohort). The 12-point PPCS risk score model for the derivation cohort included the variables of female sex, age of 13 years or older, physician-diagnosed migraine history, prior concussion with symptoms lasting longer than 1 week, headache, sensitivity to noise, fatigue, answering questions slowly, and 4 or more errors on the Balance Error Scoring System tandem stance. The area under the curve was 0.71 (95% CI, 0.69-0.74) for the derivation cohort and 0.68 (95% CI, 0.65-0.72) for the validation cohort. CONCLUSIONS AND RELEVANCE: A clinical risk score developed among children presenting to the emergency department with concussion and head injury within the previous 48 hours had modest discrimination to stratify PPCS risk at 28 days. Before this score is adopted in clinical practice, further research is needed for external validation, assessment of accuracy in an office setting, and determination of clinical utility.},

abstract = {BACKGROUND: Better diagnostic and prognostic tools are needed to address issues related to early diagnosis and management of concussion across the continuum of aging but particularly in children and adolescents. The purpose of the current study was to evaluate the reliability of robotic technology (KINARM robot) assessments of reaching, position sense, bimanual motor function, visuospatial skills, attention and decision making in youth ice hockey players (ages 10-14). METHODS: Thirty-four male children attended two testing days, one week apart. On day one, each subject completed five tasks on the robot with two examiners (alternating examiner sequence); the 2(nd) examiner followed the same procedure as the 1(st) immediately afterwards. One consistent examiner tested subjects one week later. This is a test-retest reliability study. The robotic tasks characterize sensorimotor and/or cognitive performance; 63 parameters from 5 tasks are reported. Session 1 was the 1(st) time the subject performed the 5 tasks, session 2 the 2(nd) time on day 1, and session 3 one week following. RESULTS: Intra-class correlation coefficients ranged from 0.06 to 0.91 and 0.09 to 0.90 for session 1 to 2 and 2 to 3, respectively. Bland-Altman plots showed agreement in a majority of the parameters and a learning effect in 25 % and 24 % of parameters in session 1 vs 2 and 1 vs 3, respectively but none for session 2 vs 3. Of those that showed a learning effect, only 8 % of parameters in session 1 vs 2 and 10 % in session 1 vs 3 had a clinical relevance measure\>0.8. CONCLUSIONS: The relative homogeneity of the sample and the effect of learning seen in some of the task parameters appears to have negatively impacted the intra-class correlation coefficients from session 1 to 2, with less impact for 2 to 3. The Bland-Altman analysis supports good absolute reliability in healthy male children with no neurological impairment ranging in age from 10 to 14. The clinically relevant learning effect seen, in a small number of parameters could be addressed by creating a learning effect adjustment factor and/or implementing a practice session, which would eliminate the learning effect.},

abstract = {BACKGROUND: The benefit of preseason concussion education on athletes' knowledge, attitudes, and behaviors is unclear. The purpose of the study was to determine the influence of preseason concussion education on knowledge and self-reported attitudes and reporting behaviors. We hypothesized that preseason education would lead to better knowledge and self-reported attitudes and better reporting of concussion symptoms during the season. METHODS: This study involved a prospective cohort comparing the benefits of a preseason lectured-based concussion education session at one high school with a control school. Participants included males and females age 13 years to 18 years from two community high schools who were participating in higher concussion risk, fall or winter sports (football, soccer, wrestling, and basketball). The education school and control school included 234 and 262 participants, respectively. Outcomes were a preseason and postseason survey assessing knowledge and self-reported attitudes about concussions and an end-of-season questionnaire assessing concussion reporting behaviors during the season. RESULTS: Total scores on the combined (p \< 0.0001), knowledge-based (p = 0.016), and behavioral-based (p \< 0.0001) questions demonstrated statistically significant improvement in the education group. Scores peaked immediately after education but dissipated at the end of the season. There was a lower proportion in the education school (72%) compared with the control school (88%) that reported continued play despite having concussion symptoms during the season (p = 0.025). A similar proportion of athletes diagnosed with concussion during the season in the education (27%) and control schools (23%) reported returning to play before symptoms resolved (p = 0.81). CONCLUSION: These findings suggest that a didactic-based preseason concussion education likely has minimal benefits. Other factors besides knowledge are likely influencing student-athlete concussion reporting behavior. Future research focused on changing the culture of concussion reporting is needed. LEVEL OF EVIDENCE: Therapeutic study, level III.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

An observational prospective study was conducted. From 2007, the World Footballers' Union (FIFPro) and its related national footballers' unions (more than 70 countries distributed across all continents) collected descriptive data (football-related, cause, etc.) on mortality of active (during career) and recently retired (postcareer before reaching 45 years of age) professional footballers by means of several official sources. A total of 214 deaths were recorded among active and recently retired professional footballers, leading to an overall mortality rate of 0.47 per 1000 footballers per year. Of the 214 deaths, 183 were recorded among active players and 31 among recently retired players. Among the active players, 17% of the fatalities were related to football participation. Disease was the leading cause of death among professional footballers (55%), of which up to 33% accounted for suspected cardiac pathology. Accidents accounted for 25% of the overall deaths, and suicide for 11%. From 2007 to 2013, 214 deaths were recorded among active (during career) and recently retired (post career) professional footballers. Leading cause of death was disease (55%), one third of which were accounted for by suspected cardiac pathology, while accidents accounted for 25% of all deaths, and suicide for 11%. Attention to the predictive validity and application of heart-related precompetition medical assessment should be given, and mental health support should be developed and implemented both during and after a professional football career to prevent potential suicidal behaviors.},

abstract = {Context: Analysis of health care service models requires the collection and evaluation of basic practice characterization data. Practice-based research networks (PBRNs) provide a framework for gathering data useful in characterizing clinical practice. Objective: To describe preliminary secondary school setting practice data from the Athletic Training Practice-Based Research Network (AT-PBRN). Design: Descriptive study. Setting: Secondary school athletic training facilities within the AT-PBRN. Patients or Other Participants: Clinicians (n = 22) and their patients (n = 2523) from the AT-PBRN. Main Outcome Measure(s): A Web-based survey was used to obtain data on clinical practice site and clinician characteristics. Patient and practice characteristics were obtained via deidentified electronic medical record data collected between September 1, 2009, and April 1, 2011. Descriptive data regarding the clinician and CPS practice characteristics are reported as percentages and frequencies. Descriptive analysis of patient encounters and practice characteristic data was performed, with the percentages and frequencies of the type of injuries recorded at initial evaluation, type of treatment received at initial evaluation, daily treatment, and daily sign-in procedures. Results: The AT-PBRN had secondary school sites in 7 states, and most athletic trainers at those sites (78.2%) had less than 5 years of experience. The secondary school sites within the AT-PBRN documented 2523 patients treated across 3140 encounters. Patients most frequently sought care for a current injury (61.3%), followed by preventive services (24.0%), and new injuries (14.7%). The most common diagnoses were ankle sprain/strain (17.9%), hip sprain/strain (12.5%), concussion (12.0%), and knee pain (2.5%). The most frequent procedures were athletic trainer evaluation (53.9%), hot- or cold-pack application (26.0%), strapping (10.3%), and therapeutic exercise (5.7%). The median number of treatments per injury was 3 (interquartile range = 2, 4; range = 2-19). Conclusions: These preliminary data describe services provided by clinicians within the AT-PBRN and demonstrate the usefulness of the PBRN model for obtaining such data.},

DESIGN: Prospective evaluation of leisure participation at 1 year after TBI. SETTING: Level I trauma center. PARTICIPANTS: Rehabilitation inpatients (mean age, 35.3 years; 77% male; 77% white) with moderate to severe TBI (N=160). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Functional Status Examination. RESULTS: At 1 year after injury, 81% had not returned to preinjury levels of leisure participation. Activities most frequently discontinued included partying, drug and alcohol use, and various sports. The activity most often reported as new after injury was watching television. Of the small fraction who returned to preinjury levels, 70% did so within 4 months of injury. Sixty percent of those who did not return to preinjury levels were moderately to severely bothered by the changes. CONCLUSIONS: At 1 year after injury, many TBI survivors engage in a reduced number of leisure activities, which are more sedentary and less social, with a substantial fraction dissatisfied with these changes. While discontinuing some activities may be viewed as a positive change, there are few new ones to replace them.},

abstract = {In 1991, a population-based epidemiologic traumatic brain injury (TBI) study was done in urban and rural areas of Taiwan; this was 5 years before the helmet use law was passed and 8 years before the drink driving law was passed. In order to evaluate the impact of three major determinants (time, geography, and legislation) on the epidemiology of TBI, we conducted a prospective study in 2001 and used the 1991 data to examine the differences in TBI distribution in urban and rural Taiwan a decade after these laws were passed. In 2001, 5754 TBI cases were collected from the urban area of Taipei City, and 1474 TBI cases were collected from the rural area of Hualien County. The TBI incidence rate in Taipei City in 2001 was estimated to be 218/100,000 population (285/100,000 for males and 152/100,000 for females). When compared to the 1991 data, the incidence rate in 2001 had increased by 20%. The TBI incidence rate in Hualien County in 2001 was estimated to be 417/100,000 population (516/100,000 for males and 306/100,000 for females); this was a 37% increase over the 1991 data. Our study found that the distribution of causes and age distribution had shifted significantly over the 10-year period. In 2001, the age group with the highest incidence was 20-29 years, while in 1991 it had been the over 70 years age group. While traffic-related TBI had decreased, falls and assaults had increased in 2001. We also found that legislation, such as the helmet law, affects TBI distribution by decreasing the traffic-related TBI rate, decreasing the admission severity of TBI, and reducing TBI-related mortality. Finally, geography plays a crucial role in the outcome of TBI; over the 10 year period, Taipei had an increase in moderately severe outcomes, while Hualien had an increase in more severe outcomes. Comparative studies of TBI in urban and rural areas have shown that time, legislation, and geography are crucial determinants of TBI epidemiology. Although time and legal interventions seem to have more of an impact, geography does affect TBI outcomes.},

abstract = {OBJECTIVES: To assess the role of brain networks in emotion regulation and post-traumatic complaints in the sub-acute phase after non-complicated mild traumatic brain injury (mTBI). EXPERIMENTAL DESIGN: Fifty-four patients with mTBI (34 with and 20 without complaints) and 20 healthy controls (group-matched for age, sex, education, and handedness) were included. Resting-state fMRI was performed at four weeks post-injury. Static and dynamic functional connectivity were studied within and between the default mode, executive (frontoparietal and bilateral frontal network), and salience network. The hospital anxiety and depression scale (HADS) was used to measure anxiety (HADS-A) and depression (HADS-D). PRINCIPAL OBSERVATIONS: Regarding within-network functional connectivity, none of the selected brain networks were different between groups. Regarding between-network interactions, patients with complaints exhibited lower functional connectivity between the bilateral frontal and salience network compared to patients without complaints. In the total patient group, higher HADS-D scores were related to lower functional connectivity between the bilateral frontal network and both the right frontoparietal and salience network, and to higher connectivity between the right frontoparietal and salience network. Furthermore, whereas higher HADS-D scores were associated with lower connectivity within the parietal midline areas of the bilateral frontal network, higher HADS-A scores were related to lower connectivity within medial prefrontal areas of the bilateral frontal network. CONCLUSIONS: Functional interactions of the executive and salience networks were related to emotion regulation and complaints after mTBI, with a key role for the bilateral frontal network. These findings may have implications for future studies on the effect of psychological interventions.Copyright © 2016 Wiley Periodicals, Inc.},

abstract = {CONTEXT: Younger age has been hypothesized to be a risk factor for prolonged recovery after sport-related concussion, yet few studies have directly evaluated age differences in acute recovery. OBJECTIVE: To compare clinical recovery patterns for high school and collegiate athletes. DESIGN: Prospective cohort study. SETTING: Large, multicenter prospective sample collected from 1999-2003 in a sports medicine setting. SUBJECTS: Concussed athletes (n = 621; 545 males and 76 females) and uninjured controls (n = 150) participating in high school and collegiate contact and collision sports (79% in football, 15.7% in soccer, and the remainder in lacrosse or ice hockey). MAIN OUTCOME MEASURE(S): Participants underwent evaluation of symptoms (Graded Symptom Checklist), cognition (Standardized Assessment of Concussion, paper-and-pencil neuropsychological tests), and postural stability (Balance Error Scoring System). Athletes were evaluated preinjury and followed serially at several time points after concussive injury: immediately, 3 hours postinjury, and at days 1, 2, 3, 5, 7, and 45 or 90 (with neuropsychological measures administered at baseline and 3 postinjury time points). RESULTS: Comparisons of concussed high school and collegiate athletes with uninjured controls suggested that high school athletes took 1 to 2 days longer to recover on a cognitive (Standardized Assessment of Concussion) measure. Comparisons with the control group on other measures (symptoms, balance) as well as direct comparisons between concussed high school and collegiate samples revealed no differences in the recovery courses between the high school and collegiate groups on any measure. Group-level recovery occurred at or before 7 days postinjury on all assessment metrics. CONCLUSIONS: The findings suggest no clinically significant age differences exist in recovery after sport-related concussion, and therefore, separate injury-management protocols are not needed for high school and collegiate athletes.},

abstract = {IMPORTANCE: Approximately one-third of children experiencing acute concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent postconcussion symptoms (PPCS). However, validated and pragmatic tools enabling clinicians to identify patients at risk for PPCS do not exist. OBJECTIVE: To derive and validate a clinical risk score for PPCS among children presenting to the emergency department. DESIGN, SETTING, AND PARTICIPANTS: Prospective, multicenter cohort study (Predicting and Preventing Postconcussive Problems in Pediatrics [5P]) enrolled young patients (aged 5-\<18 years) who presented within 48 hours of an acute head injury at 1 of 9 pediatric emergency departments within the Pediatric Emergency Research Canada (PERC) network from August 2013 through September 2014 (derivation cohort) and from October 2014 through June 2015 (validation cohort). Participants completed follow-up 28 days after the injury. EXPOSURES: All eligible patients had concussions consistent with the Zurich consensus diagnostic criteria. MAIN OUTCOMES AND MEASURES: The primary outcome was PPCS risk score at 28 days, which was defined as 3 or more new or worsening symptoms using the patient-reported Postconcussion Symptom Inventory compared with recalled state of being prior to the injury. RESULTS: In total, 3063 patients (median age, 12.0 years [interquartile range, 9.2-14.6 years]; 1205 [39.3%] girls) were enrolled (n=2006 in the derivation cohort; n=1057 in the validation cohort) and 2584 of whom (n=1701 [85%] in the derivation cohort; n=883 [84%] in the validation cohort) completed follow-up at 28 days after the injury. Persistent postconcussion symptoms were present in 801 patients (31.0%) (n=510 [30.0%] in the derivation cohort and n=291 [33.0%] in the validation cohort). The 12-point PPCS risk score model for the derivation cohort included the variables of female sex, age of 13 years or older, physician-diagnosed migraine history, prior concussion with symptoms lasting longer than 1 week, headache, sensitivity to noise, fatigue, answering questions slowly, and 4 or more errors on the Balance Error Scoring System tandem stance. The area under the curve was 0.71 (95% CI, 0.69-0.74) for the derivation cohort and 0.68 (95% CI, 0.65-0.72) for the validation cohort. CONCLUSIONS AND RELEVANCE: A clinical risk score developed among children presenting to the emergency department with concussion and head injury within the previous 48 hours had modest discrimination to stratify PPCS risk at 28 days. Before this score is adopted in clinical practice, further research is needed for external validation, assessment of accuracy in an office setting, and determination of clinical utility.},

abstract = {BACKGROUND: Better diagnostic and prognostic tools are needed to address issues related to early diagnosis and management of concussion across the continuum of aging but particularly in children and adolescents. The purpose of the current study was to evaluate the reliability of robotic technology (KINARM robot) assessments of reaching, position sense, bimanual motor function, visuospatial skills, attention and decision making in youth ice hockey players (ages 10-14). METHODS: Thirty-four male children attended two testing days, one week apart. On day one, each subject completed five tasks on the robot with two examiners (alternating examiner sequence); the 2(nd) examiner followed the same procedure as the 1(st) immediately afterwards. One consistent examiner tested subjects one week later. This is a test-retest reliability study. The robotic tasks characterize sensorimotor and/or cognitive performance; 63 parameters from 5 tasks are reported. Session 1 was the 1(st) time the subject performed the 5 tasks, session 2 the 2(nd) time on day 1, and session 3 one week following. RESULTS: Intra-class correlation coefficients ranged from 0.06 to 0.91 and 0.09 to 0.90 for session 1 to 2 and 2 to 3, respectively. Bland-Altman plots showed agreement in a majority of the parameters and a learning effect in 25 % and 24 % of parameters in session 1 vs 2 and 1 vs 3, respectively but none for session 2 vs 3. Of those that showed a learning effect, only 8 % of parameters in session 1 vs 2 and 10 % in session 1 vs 3 had a clinical relevance measure\>0.8. CONCLUSIONS: The relative homogeneity of the sample and the effect of learning seen in some of the task parameters appears to have negatively impacted the intra-class correlation coefficients from session 1 to 2, with less impact for 2 to 3. The Bland-Altman analysis supports good absolute reliability in healthy male children with no neurological impairment ranging in age from 10 to 14. The clinically relevant learning effect seen, in a small number of parameters could be addressed by creating a learning effect adjustment factor and/or implementing a practice session, which would eliminate the learning effect.},

abstract = {BACKGROUND: The benefit of preseason concussion education on athletes' knowledge, attitudes, and behaviors is unclear. The purpose of the study was to determine the influence of preseason concussion education on knowledge and self-reported attitudes and reporting behaviors. We hypothesized that preseason education would lead to better knowledge and self-reported attitudes and better reporting of concussion symptoms during the season. METHODS: This study involved a prospective cohort comparing the benefits of a preseason lectured-based concussion education session at one high school with a control school. Participants included males and females age 13 years to 18 years from two community high schools who were participating in higher concussion risk, fall or winter sports (football, soccer, wrestling, and basketball). The education school and control school included 234 and 262 participants, respectively. Outcomes were a preseason and postseason survey assessing knowledge and self-reported attitudes about concussions and an end-of-season questionnaire assessing concussion reporting behaviors during the season. RESULTS: Total scores on the combined (p \< 0.0001), knowledge-based (p = 0.016), and behavioral-based (p \< 0.0001) questions demonstrated statistically significant improvement in the education group. Scores peaked immediately after education but dissipated at the end of the season. There was a lower proportion in the education school (72%) compared with the control school (88%) that reported continued play despite having concussion symptoms during the season (p = 0.025). A similar proportion of athletes diagnosed with concussion during the season in the education (27%) and control schools (23%) reported returning to play before symptoms resolved (p = 0.81). CONCLUSION: These findings suggest that a didactic-based preseason concussion education likely has minimal benefits. Other factors besides knowledge are likely influencing student-athlete concussion reporting behavior. Future research focused on changing the culture of concussion reporting is needed. LEVEL OF EVIDENCE: Therapeutic study, level III.},

Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},

An observational prospective study was conducted. From 2007, the World Footballers' Union (FIFPro) and its related national footballers' unions (more than 70 countries distributed across all continents) collected descriptive data (football-related, cause, etc.) on mortality of active (during career) and recently retired (postcareer before reaching 45 years of age) professional footballers by means of several official sources. A total of 214 deaths were recorded among active and recently retired professional footballers, leading to an overall mortality rate of 0.47 per 1000 footballers per year. Of the 214 deaths, 183 were recorded among active players and 31 among recently retired players. Among the active players, 17% of the fatalities were related to football participation. Disease was the leading cause of death among professional footballers (55%), of which up to 33% accounted for suspected cardiac pathology. Accidents accounted for 25% of the overall deaths, and suicide for 11%. From 2007 to 2013, 214 deaths were recorded among active (during career) and recently retired (post career) professional footballers. Leading cause of death was disease (55%), one third of which were accounted for by suspected cardiac pathology, while accidents accounted for 25% of all deaths, and suicide for 11%. Attention to the predictive validity and application of heart-related precompetition medical assessment should be given, and mental health support should be developed and implemented both during and after a professional football career to prevent potential suicidal behaviors.},

abstract = {Context: Analysis of health care service models requires the collection and evaluation of basic practice characterization data. Practice-based research networks (PBRNs) provide a framework for gathering data useful in characterizing clinical practice. Objective: To describe preliminary secondary school setting practice data from the Athletic Training Practice-Based Research Network (AT-PBRN). Design: Descriptive study. Setting: Secondary school athletic training facilities within the AT-PBRN. Patients or Other Participants: Clinicians (n = 22) and their patients (n = 2523) from the AT-PBRN. Main Outcome Measure(s): A Web-based survey was used to obtain data on clinical practice site and clinician characteristics. Patient and practice characteristics were obtained via deidentified electronic medical record data collected between September 1, 2009, and April 1, 2011. Descriptive data regarding the clinician and CPS practice characteristics are reported as percentages and frequencies. Descriptive analysis of patient encounters and practice characteristic data was performed, with the percentages and frequencies of the type of injuries recorded at initial evaluation, type of treatment received at initial evaluation, daily treatment, and daily sign-in procedures. Results: The AT-PBRN had secondary school sites in 7 states, and most athletic trainers at those sites (78.2%) had less than 5 years of experience. The secondary school sites within the AT-PBRN documented 2523 patients treated across 3140 encounters. Patients most frequently sought care for a current injury (61.3%), followed by preventive services (24.0%), and new injuries (14.7%). The most common diagnoses were ankle sprain/strain (17.9%), hip sprain/strain (12.5%), concussion (12.0%), and knee pain (2.5%). The most frequent procedures were athletic trainer evaluation (53.9%), hot- or cold-pack application (26.0%), strapping (10.3%), and therapeutic exercise (5.7%). The median number of treatments per injury was 3 (interquartile range = 2, 4; range = 2-19). Conclusions: These preliminary data describe services provided by clinicians within the AT-PBRN and demonstrate the usefulness of the PBRN model for obtaining such data.},

abstract = {OBJECTIVE: To determine how participation in leisure activities for people with traumatic brain injury (TBI) changes from before injury to 1 year after injury. DESIGN: Prospective evaluation of leisure participation at 1 year after TBI. SETTING: Level I trauma center. PARTICIPANTS: Rehabilitation inpatients (mean age, 35.3 years; 77% male; 77% white) with moderate to severe TBI (N=160). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Functional Status Examination. RESULTS: At 1 year after injury, 81% had not returned to preinjury levels of leisure participation. Activities most frequently discontinued included partying, drug and alcohol use, and various sports. The activity most often reported as new after injury was watching television. Of the small fraction who returned to preinjury levels, 70% did so within 4 months of injury. Sixty percent of those who did not return to preinjury levels were moderately to severely bothered by the changes. CONCLUSIONS: At 1 year after injury, many TBI survivors engage in a reduced number of leisure activities, which are more sedentary and less social, with a substantial fraction dissatisfied with these changes. While discontinuing some activities may be viewed as a positive change, there are few new ones to replace them.},

abstract = {In 1991, a population-based epidemiologic traumatic brain injury (TBI) study was done in urban and rural areas of Taiwan; this was 5 years before the helmet use law was passed and 8 years before the drink driving law was passed. In order to evaluate the impact of three major determinants (time, geography, and legislation) on the epidemiology of TBI, we conducted a prospective study in 2001 and used the 1991 data to examine the differences in TBI distribution in urban and rural Taiwan a decade after these laws were passed. In 2001, 5754 TBI cases were collected from the urban area of Taipei City, and 1474 TBI cases were collected from the rural area of Hualien County. The TBI incidence rate in Taipei City in 2001 was estimated to be 218/100,000 population (285/100,000 for males and 152/100,000 for females). When compared to the 1991 data, the incidence rate in 2001 had increased by 20%. The TBI incidence rate in Hualien County in 2001 was estimated to be 417/100,000 population (516/100,000 for males and 306/100,000 for females); this was a 37% increase over the 1991 data. Our study found that the distribution of causes and age distribution had shifted significantly over the 10-year period. In 2001, the age group with the highest incidence was 20-29 years, while in 1991 it had been the over 70 years age group. While traffic-related TBI had decreased, falls and assaults had increased in 2001. We also found that legislation, such as the helmet law, affects TBI distribution by decreasing the traffic-related TBI rate, decreasing the admission severity of TBI, and reducing TBI-related mortality. Finally, geography plays a crucial role in the outcome of TBI; over the 10 year period, Taipei had an increase in moderately severe outcomes, while Hualien had an increase in more severe outcomes. Comparative studies of TBI in urban and rural areas have shown that time, legislation, and geography are crucial determinants of TBI epidemiology. Although time and legal interventions seem to have more of an impact, geography does affect TBI outcomes.},
