abstract = {Sports-related concussion or traumatic brain injury (TBI) is a frequent occurrence among high school athletes. Long-term and short-term effects of TBI on the athlete’s developing brain can be minimized if the athlete reports and is effectively treated for TBI symptoms. Knowledge of concussion symptoms and a school culture of support are critical in order to promote the student’s intention to report TBI symptoms. The purpose of this systematic review is to examine the relationship between the high school athlete’s concussion knowledge and an intention to report TBI symptoms. One hundred eleven articles were retrieved and four articles met established criteria and were included in this systematic review. A link appears to exist between high school athlete concussion knowledge and an intention to report TBI symptoms. School nurses can provide a supportive environment and concussion knowledge to the high school athlete in order to ultimately facilitate TBI symptom reporting.},

abstract = {Objective This study introduces a rapid picture naming test, the Mobile Universal Lexicon Evaluation System (MULES), as a novel, vision-based performance measure for concussion screening. The MULES is a visual-verbal task that includes 54 original photographs of fruits, objects and animals. We piloted MULES in a cohort of volunteers to determine feasibility, ranges of picture naming responses, and the relation of MULES time scores to those of King-Devick (K-D), a rapid number naming test. Methods A convenience sample (n = 20, age 34 ± 10) underwent MULES and K-D (spiral bound, iPad versions). Administration order was randomized; MULES tests were audio-recorded to provide objective data on temporal variability and ranges of picture naming responses. Results Scores for the best of two trials for all tests were 40\textendash50 s; average times required to name each MULES picture (0.72 ± 0.14 s) was greater than those needed for each K-D number ((spiral: 0.33 ± 0.05 s, iPad: 0.36 ± 0.06 s, 120 numbers), p \< 0.0001, paired t-test). MULES scores showed the greatest degree of improvement between trials (9.4 ± 4.8 s, p \< 0.0001 for trials 1 vs. 2), compared to K-D (spiral 1.5 ± 3.3 s, iPad 1.8 ± 3.4 s). Shorter MULES times demonstrated moderate and significant correlations with shorter iPad but not spiral K-D times (r = 0.49, p = 0.03). Conclusion The MULES test is a rapid picture naming task that may engage more extensive neural systems than more commonly used rapid number naming tasks. Rapid picture naming may require additional processing devoted to color perception, object identification, and categorization. Both tests rely on initiation and sequencing of saccadic eye movements. © 2016 Elsevier B.V.},

abstract = {Objective: Pediatric concussion is an extensive public health concern with a complex clinical presentation. Balance assessment has been well-studied in the adult population, but has been limited in children. We aimed to assess the reliability and minimum detectable change (MDC) of the Balance Error Scoring System (BESS) in healthy children. Design: This prospective observational study included 373 healthy children aged 5 to 14. Interrater reliability was assessed by having 4 assessors review videos of 50 random subjects distributed evenly by age and sex across the entire cohort. Intrarater reliability was performed by having assessors review videos of other assessors' live evaluations. Test-retest reliability was obtained by comparing BESS scores as recorded live at the 2 separate time points by the same rater. Setting: Local elementary and junior high schools. Participants: Three hundred and seventy three healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Main Outcome Measures: Intraclass Correlation Coefficients (ICCs) and MDC Scores. Results: The overall interrater ICC was determined to be 0.93 [95% confidence interval (CI), 0.79-0.97] and intrarater ICC was 0.96 (95% CI, 0.95-0.97) with individual intrarater ICCs ranging between 0.69 and 0.99. The test-retest reliability was 0.90 (95% CI, 0.88- 0.92). The MDCs were 9.6, 4.6, and 7.3 points at the 95% CIs for interrater, intrarater, and test-retest comparisons, respectively. No learning effect was seen. Conclusions: The BESS demonstrates excellent reliability in the pediatric population without evidence of a learning effect. © 2016 Wolters Kluwer Health, Inc.

abstract = {Objective: ImPACT® (Immediate Post-Concussion Assessment and Cognitive Testing) is a computerized neuropsychological screening battery, which is widely used to measure the acute effects of sport-related concussion and to monitor recovery from injury. This study examined the factor structure of ImPACT® in several samples of high school student athletes. We hypothesized that a 2-factor structure would be present in all samples. Method: A sample of 4,809 adolescent student athletes was included, and subgroups with a history of treatment for headaches or a self-reported history of learning problems or attention-deficit hyperactivity disorder were analyzed separately. Exploratory principal axis factor analyses with Promax rotations were used. Results: As hypothesized, both the combination of Verbal Memory and Visual Memory Composite scores loaded on one (Memory) factor, while Visual Motor Speed and Reaction Time loaded on a different (Speed) factor, in the total sample and in all subgroups. Conclusion: These results provide reasonably compelling evidence, across multiple samples, which ImPACT® measures 2 distinct factors: memory and speed. [ABSTRACT FROM AUTHOR]},

abstract = {Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12\textendash19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players. [ABSTRACT FROM AUTHOR]},

abstract = {The aim of this study was to evaluate longitudinal changes in the diffusion characteristics of brain white matter (WM) in collegiate athletes at three time points: prior to the start of the football season (T1), after one season of football (T2), followed by six months of no-contact rest (T3). Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints. Average diffusion values were obtained from statistically significant clusters for each individual. No athlete suffered a concussion during the study period. After one season of play (T1 to T2), we observed a significant increase in trace in a cluster located in the brainstem and left temporal lobe, and a significant increase in FA in the left parietal lobe. After six months of no-contact rest (T2 to T3), there was a significant decrease in trace and FA in clusters that were partially overlapping or in close proximity with the initial clusters (T1 to T2), with no significant changes from T1 to T3. Repetitive head impacts (RHI) sustained during a single football season may result in alterations of the brain’s WM in collegiate football players. These changes appear to return to baseline after 6 months of no-contact rest, suggesting remission of WM alterations. Our preliminary results suggest that collegiate football players might benefit from periods without exposure to RHI. (PsycINFO Database Record (c) 2017 APA, all rights reserved)},

abstract = {Background: Epidemiological studies suggest that the athletic population has a significant need for vision care. Recently, there has been an increased awareness and discussion of sports-related concussion, which can have a negative impact on athletic performance. The goal of this investigation is to characterize baseline performance of a cohort of elite athletes on a battery of sports vision tests. This information can: 1) serve as a baseline for comparison after an athlete is concussed, 2) help evaluate the effects of concussion on the visual system as it relates to athletic performance, and 3) help establish vision-related criteria for determining if and when an athlete is ready to return to play and perform at pre-concussive levels. Methods: Twenty-one male Major League Soccer athletes ages 18-35 were tested on 20 sports vision-related tests. Results: Eighteen of 21 subjects (86%) demonstrated one or more clinically significant problems with visual acuity, ocular health, binocular vision, and/or exhibited visual symptoms. The screening results indicate that 17% failed visual acuity, 26% displayed abnormal ocular health findings, 6% exhibited binocular vision problems, and 29% complained of at least one visual symptom related to a previous incident involving head trauma or concussion. Conclusion: This visual performance testing characterized baseline findings for this population and may help determine how deficits may interfere with optimum athletic performance at the elite level. The baseline testing could also serve as an indicator of recovery in acute vs. chronic stages and help determine if and when a concussed athlete is ready to return to play.

abstract = {Surrogate model-based multi-objective design optimization was performed to reduce concussion risk during frontal football helmet impacts. In particular, a topological decomposition of the football helmet facemask was performed to formulate the design problem, and brain injury metrics were exploited as objective functions. A validated finite element model of a helmeted human head was used to recreate facemask impacts. Due to the prohibitive computational expense of the full scale simulations, a surrogate modeling approach was employed. An optimal surrogate model selection framework, called Concurrent Surrogate Model Selection, or COSMOS, was utilized to identify the surrogate models best suited to approximate each objective function. The resulting surrogate models were implemented in the Non-dominated Sorting Genetic Algorithm II (NSGA-II) optimization algorithm. Constraints were implemented to control the solid material fraction in the facemask design space, and binary variables were used to control the placement of the facemask bars. The optimized facemask designs reduced the maximum tensile pressure in the brain by 7.5% and the maximum shear strain by a remarkable 39.5%. This research represents a first-of-its-kind approach to multi-objective design optimization on a football helmet, and demonstrates the possibilities that are achievable in improving human safety by using such a simulation-based design optimization. © 2016 Elsevier Ltd},

abstract = {Objective: The objective of this paper is to review existing literature surrounding the utility of the King-Devick test which is a commonly used sideline assessment tool for sport-related concussions. Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

However, modified headgear studies have demonstrated that significant improvements in impact energy attenuation performance are possible with small design changes, such as increases in foam density and thickness. A literature review of the design, performance and use of headgear in Australian football, rugby league and rugby union was conducted. A total of 23 articles were identified using primary and secondary search strategies, which included epidemiological field studies, laboratory impact test studies and studies investigating the behaviours and attitudes of players. The results of the review were synthesised and used to identify injury reduction objectives and appropriate design criteria. The need for a headgear standard was identified and performance requirements were discussed, which drew upon human tolerance and sports-specific head impact exposure data. Usability and behavioural issues, which require consideration during the design process, were also assessed. © IMechE 2015.},

Despite this increased interest, there remains limited knowledge about the potential influence of significant others (e.g, parents, coaches, and teammates) on young athletes concerning the Return to Play (RTP) process following a concussion. The purpose of this exploratory study was to examine the perceived social influences on female youth ice hockey players’ RTP following a concussion. Using a phenomenological approach, five female competitive youth ice hockey players (Mage = 12.2) were interviewed to gain insight into their experiences during the RTP process. Coaches, teammates, parents, siblings, and teachers were found to play a significant role in RTP. With regards to influences from others, four common themes emerged: Compassion, Support, Protection and Pressure. Study findings support the importance of concussion management education systems for coaches, parents, and athletes. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: We review the general topic of traumatic brain injury (TBI) and our research utilizing transcranial photobiomodulation (tPBM) to improve cognition in chronic TBI using red/near-infrared (NIR) light-emitting diodes (LEDs) to deliver light to the head. tPBM improves mitochondrial function increasing oxygen consumption, production of adenosine triphosphate (ATP), and improving cellular energy stores. Nitric oxide is released from the cells increasing regional blood flow in the brain. Review of published studies: In our previously published study, 11 chronic TBI patients with closed-head TBI caused by different accidents (motor vehicle accident, sports-related, improvised explosive device blast injury) and exhibiting long-lasting cognitive dysfunction received 18 outpatient treatments (Monday, Wednesday, Friday for 6 weeks) starting at 10 months to 8 years post-TBI. LED therapy is nonthermal, painless, and noninvasive. An LED-based device classified as nonsignificant risk (FDA cleared) was used. Each LED cluster head (5.35 cm diameter, 500mW, 22.2 mW/cm2) was applied for 9 min 45 sec (13 J/cm2) using 11 locations on the scalp: midline from front-to-back hairline and bilaterally on frontal, parietal, and temporal areas. Testing was performed before and after transcranial LED (tLED; at 1 week, 1 month, and at 2 months after the 18th treatment) and showed significant improvements in executive function and verbal memory. There were also fewer post-traumatic stress disorder (PTSD) symptoms reported. Ongoing studies: Ongoing, current studies involve TBI patients who have been treated with tLED using either 26 J/cm2 per LED location on the head or treated with intranasal only (iLED) using red (633 nm) and NIR (810 nm) diodes placed into the nostrils. The NIR iLED is hypothesized to deliver photons to the hippocampus, and the red 633 nm iLED is believed to increase melatonin. Results have been similar to the previously published tLED study. Actigraphy sleep data showed increased time asleep (on average one additional hour per night) after the 18th tLED or iLED treatment. LED treatments may be performed in the home. Sham-controlled studies with veterans who have cognitive dysfunction from Gulf War Illness, blast TBI, and TBI/PTSD are currently ongoing. © Mary Ann Liebert, Inc.},

(The following abstract of the original article appeared in record [rid]2016-18089-008[/rid]). This exploratory study was designed to examine the neuropsychological effects of sports-related head trauma\textemdashspecifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n = 282), grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high-contact-sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low-contact sports (wrestling, soccer, baseball, judo, and basketball). This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high-contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: Pediatric head injuries occur commonly and are being reported in increasing numbers. Balance testing is a key component in the evaluation of suspected concussion, and the balance error scoring system (BESS) is likely the most well-known and widely used measure. To date, normative BESS scores for adults have been reported but not for children. Design: Normative data for BESS scores and modified BESS scores were created in a cohort of healthy children. Potential variables were analyzed as predictors of BESS performance. Setting: Local elementary and junior high schools. Participants: A total of 373 healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Assessment of Risk Factors: Gender, body mass index percentile, previous concussions, athletic participation, age, and the parental opinion of child's balance ability were examined as factors associated with the BESS score. Main Outcome Measures: BESS scores. Results: Normative data are reported, stratified by age groups of 5 to 7 years, 8 to 10 years, and 11 to 14 years of age, for both BESS and modified BESS. Median BESS scores are 23 for children aged 5 to 7, 18 for children aged 8 to 10, and 16 for children aged 11 to 14. Median modified BESS scores are 8 for children age 5 to 7, 5 for children age 8 to 10, and 4 for children age 11 to 14. Increasing age and positive parental opinion regarding their child's balance ability were independently correlated with decreasing BESS scores (P \< 0.01). Conclusions: The normative data on BESS scores for healthy children reported here provide age-stratified reference values for suspected balance alterations. © 2015 Wolters Kluwer Health, Inc.

abstract = {It is standard practice in high school athletic programs for certified athletic trainers to evaluate and treat injured student athletes. In some cases, a trainer refers an athlete to a physician for definitive medical management. This study was conducted to determine the rate of agreement between athletic trainers and physicians regarding assessment of injuries in student athletes. All high school athletes who were injured between 2010 and 2012 at 5 regional high schools were included in a research database. All patients who were referred for physician evaluation and treatment were identified and included in this analysis. A total of 286 incidents met the inclusion criteria. A total of 263 (92%) of the athletic trainer assessments and physician diagnoses were in agreement. In the 23 cases of disagreement, fractures and sprains were the most common injuries. Kappa analysis showed the highest interrater agreement in injuries classified as dislocations and concussions and the lowest interrater agreement in meniscal/labral injuries and fractures. In the absence of a confirmed diagnosis, agreement among health care providers can be used to infer accuracy. According to this principle, as agreement between athletic trainers and physicians improves, there is a greater likelihood of arriving at the correct assessment and treatment plan. Athletic trainers are highly skilled professionals who are well trained in the evaluation of athletic injuries. The current study showed that additional training in identifying fractures may be beneficial to athletic trainers and the athletes they treat. [Orthopedics. 2016; 39(5):e944-e949.].

abstract = {Sports-related brain concussion is not well known despite its frequency. Few cases are reported. Brain concussion leads to an immediate transient alteration of the neurological functions followed by a post-concussion syndrome of variable duration. Due to the risk of neurodegenerative disease related to repeated concussion, we created a specialized outpatient clinic devoted to sports-related brain concussions in order to better apprehend the phenomenon, to search for factors predictive of unfavorable outcome, and most importantly to elaborate a protocol and a set of criteria for determining the moment the incriminated activity can be resumed under good conditions. The cohort included 211 athletes who attended the specialized outpatient clinic, 168 men and 43 women. The largest number of patients were rugby players (n = 166, 78.7%). Among the 211 athletes, 126 (59.7%) had already had one concussion and 132 attended the clinic twice, at most four days after the concussion. The diagnosis was considered on the playing field, generally because of the presence of amnesia or loss of consciousness. Among the 211 athletes, 106 (50.2%) left the field immediately after the concussion. For the post-concussion syndrome, headache was the most common functional sign (170/211, 80.6%). Age (\< 20 years), female gender, and recent history of a brain concussion were factors predictive of poor outcome as measured by the duration of the post-concussion syndrome and delay before returning to the sports activity. Loss of consciousness, anterograde or retrograde amnesia, and the number of episodes of prior brain concussion did not have any impact on the duration of the post-concussion syndrome and delay before returning to the sports activity. In our opinion, a specialized outpatient clinic visit less than four days after the concussion can help reduce the length of the post-concussion syndrome, mainly resulting from good patient education and better therapeutic management. © 2016},

The objectives of this study were (a) to contrast the injuries in Canadian and American football players aged 6 to 17 years and (b) compare the injuries sustained during organized football with those in nonorganized football. Methods. Using a retrospective cohort design based on data from the Canadian Hospitals Injury Reporting and Prevention Program and the National Electronic Injury Surveillance System a comparison of injuries was made. Results. Trends in injuries were comparable. Proportions and odds of injuries were similar, except for a few exceptions. In Canada, more girls were injured and fractures were more prevalent. Compared with nonorganized football, organized football players were older, involved more males, and suffered more traumatic brain injuries and injuries to their lower extremities. Conclusion. Canadian and American youth football injuries were similar. The type of football, be it organized or nonorganized, has an impact on injuries. © 2016 The Author(s).},

abstract = {The collision accident in collegiate football game was simulated based on the game video and the concussive impact on the head was analyzed. First, the collision motion of players was reproduced based on the video by using motion analysis, and the translational and rotational velocities, relative position and contact location of the struck and the striking players' heads just before the collision were calculated. Then the data obtained were input to two helmeted finite element (FE) human head models as the initial condition, and the brain injury risk was evaluated by using the impact analysis. The FE helmet model was validated by a drop test of the helmet in which the head impactor was embedded. In the present study, two concussion suspected accident cases were analyzed; then the concussion was evaluated by ten mechanical parameters generated inside the skull caused by the collision. The injury risk evaluated by multi parameters belonged to the dangerous range that may cause concussion and was consistent with the diagnosis of the medical team doctor. The brain injury risk can be successfully estimated by the reconstructed simulation of the game video and FE analysis. To our knowledge, this study is the first attempt in Japan to estimate the brain injury risk systematically by a combination of game video analysis which is originally introduced for the players' health care and FE analysis by helmeted human head model. In the future, brain injury risk caused by an accident can be evaluated with higher accuracy by analyzing more accident cases. © 2016 The Japan Society of Mechanical Engineers.},

Methods: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Results: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p \< 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores.

abstract = {Purpose: Approximately 90% of concussions are transient, with symptoms resolving within 10\textendash14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. Methods: We conducted a retrospective study of 52 pediatric patients with persistent post-concussion symptoms after 3 months. We collected demographics and neuroimaging results obtained greater than 2 weeks post-concussion. Neuroimaging ordered in the first 2 weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. Results: Of 52 patients with PCS, 23/52 (44 %) had neuroimaging at least 2 weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3 %), 1/8 CTs (13 %), and 0/5 x-rays (0 %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric patients totaled $129,025. We estimate the cost to identify a single positive finding was $21,000 for head CT and $104,500 for brain MRI. Conclusions: In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase. © 2015, Springer-Verlag Berlin Heidelberg.},

abstract = {Emerging research on the long-term impact of concussions on athletes has allowed public recognition of the potentially devastating effects of these and other mild head injuries. Mild traumatic brain injury (mTBI) is a multifaceted disease for which management remains a clinical challenge. Recent pre-clinical and clinical data strongly suggest a destructive synergism between brain temperature elevation and mTBI; conversely, brain hypothermia, with its broader, pleiotropic effects, represents the most potent neuro-protectant in laboratory studies to date. Although well-established in selected clinical conditions, a systemic approach to accomplish regional hypothermia has failed to yield an effective treatment strategy in traumatic brain injury (TBI). Furthermore, although systemic hypothermia remains a potentially valid treatment strategy for moderate to severe TBIs, it is neither practical nor safe for mTBIs. Therefore, selective head-neck cooling may represent an ideal strategy to provide therapeutic benefits to the brain. Optimizing brain temperature management using a National Aeronautics and Space Administration (NASA) spacesuit spinoff head-neck cooling technology before and/or after mTBI in contact sports may represent a sensible, practical, and effective method to potentially enhance recover and minimize post-injury deficits. In this paper, we discuss and summarize the anatomical, physiological, preclinical, and clinical data concerning NASA spinoff head-neck cooling technology as a potential treatment for mTBIs, particularly in the context of contact sports. © 2015 Huan Wang et al., licensee De Gruyter Open.},

abstract = {OBJECT: The objectives of this study were twofold: (1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and (2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population. METHODS: The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized. RESULTS: One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1-8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes. Interventions for patients with postinjury psychiatric outcomes included pharmacological therapy alone in 2 patients (10%), cognitive behavioral therapy alone in 4 (20%), multimodal therapy in 9 (45%), and no treatment in 5 (25%). Overall, 5 (25%) of the patients with postinjury psychiatric disorders were medically cleared to return to full sports participation, whereas 5 (25%) were lost to follow-up and 9 (45%) remained in treatment by the multidisciplinary concussion program at the end of the study period. One patient who was asymptomatic at the time of initial consultation committed suicide. CONCLUSIONS: Emotional symptoms were commonly reported among pediatric patients with SRC referred to a multidisciplinary pediatric concussion program. In some cases, these symptoms contributed to the development of an NPD, isolated suicidal ideation, and worsening symptoms of a preexisting psychiatric disorder. Future research is needed to clarify the prevalence, pathophysiology, risk factors, and evidence-based management of postinjury psychiatric outcomes after pediatric SRC. Successful management of these patients requires prompt recognition and multidisciplinary care by experts with clinical training and experience in concussion and psychiatry.},

abstract = {Biomechanical studies of concussions have progressed from qualitative observations of head impacts to physical and numerical reconstructions, direct impact measurements, and finite element analyses. Supplementary to a previous study, which investigated maximum principal strain, the current study used a detailed finite element head model to simulate unhelmeted concussion and no-injury head impacts and evaluate the effectiveness of various tissue-level brain injury predictors: strain rate, product of strain and strain rate, cumulative strain damage measure, von Mises stress, and intracranial pressure. Von Mises stress was found to be the most effective predictor of concussion. It was also found that the thalamus and corpus callosum were brain regions with strong associations with concussion. Tentative tolerance limits for tissue-level predictors were proposed in an attempt to broaden the understanding of unhelmeted concussions. For the thalamus, tolerance limits were proposed for a 50% likelihood of concussion: 2.24 kPa, 24.0 s-1, and 2.49 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. For the corpus callosum, tolerance limits were proposed for a 50% likelihood of concussion: 3.51 kPa, 25.1 s-1, and 2.76 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. © 2015 Human Kinetics, Inc.},

Risk factors associated with chronic traumatic encephalopathy include playing contact sports, presence of the apolipoprotein E4, and old age. Although it shares certain histopathological findings with Alzheimer disease, chronic traumatic encephalopathy has a more specific presentation (hyperphosphorylated tau protein deposited as neurofibrillary tangles, associated with neuropil threads and sometimes with beta-amyloid plaques). Its clinical presentation is insidious; patients show mild cognitive and emotional symptoms before progressing to parkinsonian motor signs and finally dementia. Results from new experimental diagnostic tools are promising, but these tools are not yet available. The mainstay of managing this disease is prevention and early detection of its first symptoms. © 2014 Sociedad Espa\~{n}ola de Neurologi´a.},

A person with a mild TBI may remain conscious or may experience a loss of consciousness for a few seconds or minutes. Other symptoms of mild TBI include headache, confusion, lightheadedness, dizziness, blurred vision or tired eyes, ringing in the ears, bad taste in the mouth, fatigue or lethargy, a change in sleep patterns, behavioral or mood changes, and trouble with memory, concentration, attention, or thinking. A person with a moderate or severe TBI may show these same symptoms, but may also have a headache that gets worse or does not go away, repeated vomiting or nausea, convulsions or seizures, an inability to awaken from sleep, dilation of one or both pupils of the eyes, slurred speech, weakness or numbness in the extremities, loss of coordination, and increased confusion, restlessness, or agitation.

Knowledge of concussion symptoms and a school culture of support are critical in order to promote the student’s intention to report TBI symptoms. The purpose of this systematic review is to examine the relationship between the high school athlete’s concussion knowledge and an intention to report TBI symptoms. One hundred eleven articles were retrieved and four articles met established criteria and were included in this systematic review. A link appears to exist between high school athlete concussion knowledge and an intention to report TBI symptoms. School nurses can provide a supportive environment and concussion knowledge to the high school athlete in order to ultimately facilitate TBI symptom reporting.},

abstract = {Objective This study introduces a rapid picture naming test, the Mobile Universal Lexicon Evaluation System (MULES), as a novel, vision-based performance measure for concussion screening. The MULES is a visual-verbal task that includes 54 original photographs of fruits, objects and animals. We piloted MULES in a cohort of volunteers to determine feasibility, ranges of picture naming responses, and the relation of MULES time scores to those of King-Devick (K-D), a rapid number naming test. Methods A convenience sample (n = 20, age 34 ± 10) underwent MULES and K-D (spiral bound, iPad versions). Administration order was randomized; MULES tests were audio-recorded to provide objective data on temporal variability and ranges of picture naming responses. Results Scores for the best of two trials for all tests were 40\textendash50 s; average times required to name each MULES picture (0.72 ± 0.14 s) was greater than those needed for each K-D number ((spiral: 0.33 ± 0.05 s, iPad: 0.36 ± 0.06 s, 120 numbers), p \< 0.0001, paired t-test). MULES scores showed the greatest degree of improvement between trials (9.4 ± 4.8 s, p \< 0.0001 for trials 1 vs. 2), compared to K-D (spiral 1.5 ± 3.3 s, iPad 1.8 ± 3.4 s). Shorter MULES times demonstrated moderate and significant correlations with shorter iPad but not spiral K-D times (r = 0.49, p = 0.03). Conclusion The MULES test is a rapid picture naming task that may engage more extensive neural systems than more commonly used rapid number naming tasks. Rapid picture naming may require additional processing devoted to color perception, object identification, and categorization. Both tests rely on initiation and sequencing of saccadic eye movements. © 2016 Elsevier B.V.},

abstract = {Objective: Pediatric concussion is an extensive public health concern with a complex clinical presentation. Balance assessment has been well-studied in the adult population, but has been limited in children. We aimed to assess the reliability and minimum detectable change (MDC) of the Balance Error Scoring System (BESS) in healthy children. Design: This prospective observational study included 373 healthy children aged 5 to 14. Interrater reliability was assessed by having 4 assessors review videos of 50 random subjects distributed evenly by age and sex across the entire cohort. Intrarater reliability was performed by having assessors review videos of other assessors' live evaluations. Test-retest reliability was obtained by comparing BESS scores as recorded live at the 2 separate time points by the same rater. Setting: Local elementary and junior high schools. Participants: Three hundred and seventy three healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Main Outcome Measures: Intraclass Correlation Coefficients (ICCs) and MDC Scores. Results: The overall interrater ICC was determined to be 0.93 [95% confidence interval (CI), 0.79-0.97] and intrarater ICC was 0.96 (95% CI, 0.95-0.97) with individual intrarater ICCs ranging between 0.69 and 0.99. The test-retest reliability was 0.90 (95% CI, 0.88- 0.92). The MDCs were 9.6, 4.6, and 7.3 points at the 95% CIs for interrater, intrarater, and test-retest comparisons, respectively. No learning effect was seen. Conclusions: The BESS demonstrates excellent reliability in the pediatric population without evidence of a learning effect. © 2016 Wolters Kluwer Health, Inc.

This study examined the factor structure of ImPACT® in several samples of high school student athletes. We hypothesized that a 2-factor structure would be present in all samples. Method: A sample of 4,809 adolescent student athletes was included, and subgroups with a history of treatment for headaches or a self-reported history of learning problems or attention-deficit hyperactivity disorder were analyzed separately. Exploratory principal axis factor analyses with Promax rotations were used. Results: As hypothesized, both the combination of Verbal Memory and Visual Memory Composite scores loaded on one (Memory) factor, while Visual Motor Speed and Reaction Time loaded on a different (Speed) factor, in the total sample and in all subgroups. Conclusion: These results provide reasonably compelling evidence, across multiple samples, which ImPACT® measures 2 distinct factors: memory and speed. [ABSTRACT FROM AUTHOR]},

abstract = {Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12\textendash19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players. [ABSTRACT FROM AUTHOR]},

Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints. Average diffusion values were obtained from statistically significant clusters for each individual. No athlete suffered a concussion during the study period. After one season of play (T1 to T2), we observed a significant increase in trace in a cluster located in the brainstem and left temporal lobe, and a significant increase in FA in the left parietal lobe. After six months of no-contact rest (T2 to T3), there was a significant decrease in trace and FA in clusters that were partially overlapping or in close proximity with the initial clusters (T1 to T2), with no significant changes from T1 to T3. Repetitive head impacts (RHI) sustained during a single football season may result in alterations of the brain’s WM in collegiate football players. These changes appear to return to baseline after 6 months of no-contact rest, suggesting remission of WM alterations. Our preliminary results suggest that collegiate football players might benefit from periods without exposure to RHI. (PsycINFO Database Record (c) 2017 APA, all rights reserved)},

abstract = {Background: Epidemiological studies suggest that the athletic population has a significant need for vision care. Recently, there has been an increased awareness and discussion of sports-related concussion, which can have a negative impact on athletic performance. The goal of this investigation is to characterize baseline performance of a cohort of elite athletes on a battery of sports vision tests. This information can: 1) serve as a baseline for comparison after an athlete is concussed, 2) help evaluate the effects of concussion on the visual system as it relates to athletic performance, and 3) help establish vision-related criteria for determining if and when an athlete is ready to return to play and perform at pre-concussive levels. Methods: Twenty-one male Major League Soccer athletes ages 18-35 were tested on 20 sports vision-related tests. Results: Eighteen of 21 subjects (86%) demonstrated one or more clinically significant problems with visual acuity, ocular health, binocular vision, and/or exhibited visual symptoms. The screening results indicate that 17% failed visual acuity, 26% displayed abnormal ocular health findings, 6% exhibited binocular vision problems, and 29% complained of at least one visual symptom related to a previous incident involving head trauma or concussion. Conclusion: This visual performance testing characterized baseline findings for this population and may help determine how deficits may interfere with optimum athletic performance at the elite level. The baseline testing could also serve as an indicator of recovery in acute vs. chronic stages and help determine if and when a concussed athlete is ready to return to play.

abstract = {Surrogate model-based multi-objective design optimization was performed to reduce concussion risk during frontal football helmet impacts. In particular, a topological decomposition of the football helmet facemask was performed to formulate the design problem, and brain injury metrics were exploited as objective functions. A validated finite element model of a helmeted human head was used to recreate facemask impacts. Due to the prohibitive computational expense of the full scale simulations, a surrogate modeling approach was employed. An optimal surrogate model selection framework, called Concurrent Surrogate Model Selection, or COSMOS, was utilized to identify the surrogate models best suited to approximate each objective function. The resulting surrogate models were implemented in the Non-dominated Sorting Genetic Algorithm II (NSGA-II) optimization algorithm. Constraints were implemented to control the solid material fraction in the facemask design space, and binary variables were used to control the placement of the facemask bars. The optimized facemask designs reduced the maximum tensile pressure in the brain by 7.5% and the maximum shear strain by a remarkable 39.5%. This research represents a first-of-its-kind approach to multi-objective design optimization on a football helmet, and demonstrates the possibilities that are achievable in improving human safety by using such a simulation-based design optimization. © 2016 Elsevier Ltd},

Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

However, modified headgear studies have demonstrated that significant improvements in impact energy attenuation performance are possible with small design changes, such as increases in foam density and thickness. A literature review of the design, performance and use of headgear in Australian football, rugby league and rugby union was conducted. A total of 23 articles were identified using primary and secondary search strategies, which included epidemiological field studies, laboratory impact test studies and studies investigating the behaviours and attitudes of players. The results of the review were synthesised and used to identify injury reduction objectives and appropriate design criteria. The need for a headgear standard was identified and performance requirements were discussed, which drew upon human tolerance and sports-specific head impact exposure data. Usability and behavioural issues, which require consideration during the design process, were also assessed. © IMechE 2015.},

abstract = {Increasing rates of concussion within youth sport has sparked interest in several related areas, such as, the psychological and physiological effects of concussion (Stein \& Meehan, 2014). Despite this increased interest, there remains limited knowledge about the potential influence of significant others (e.g, parents, coaches, and teammates) on young athletes concerning the Return to Play (RTP) process following a concussion. The purpose of this exploratory study was to examine the perceived social influences on female youth ice hockey players’ RTP following a concussion. Using a phenomenological approach, five female competitive youth ice hockey players (Mage = 12.2) were interviewed to gain insight into their experiences during the RTP process. Coaches, teammates, parents, siblings, and teachers were found to play a significant role in RTP. With regards to influences from others, four common themes emerged: Compassion, Support, Protection and Pressure. Study findings support the importance of concussion management education systems for coaches, parents, and athletes. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: We review the general topic of traumatic brain injury (TBI) and our research utilizing transcranial photobiomodulation (tPBM) to improve cognition in chronic TBI using red/near-infrared (NIR) light-emitting diodes (LEDs) to deliver light to the head. tPBM improves mitochondrial function increasing oxygen consumption, production of adenosine triphosphate (ATP), and improving cellular energy stores. Nitric oxide is released from the cells increasing regional blood flow in the brain. Review of published studies: In our previously published study, 11 chronic TBI patients with closed-head TBI caused by different accidents (motor vehicle accident, sports-related, improvised explosive device blast injury) and exhibiting long-lasting cognitive dysfunction received 18 outpatient treatments (Monday, Wednesday, Friday for 6 weeks) starting at 10 months to 8 years post-TBI. LED therapy is nonthermal, painless, and noninvasive. An LED-based device classified as nonsignificant risk (FDA cleared) was used. Each LED cluster head (5.35 cm diameter, 500mW, 22.2 mW/cm2) was applied for 9 min 45 sec (13 J/cm2) using 11 locations on the scalp: midline from front-to-back hairline and bilaterally on frontal, parietal, and temporal areas. Testing was performed before and after transcranial LED (tLED; at 1 week, 1 month, and at 2 months after the 18th treatment) and showed significant improvements in executive function and verbal memory. There were also fewer post-traumatic stress disorder (PTSD) symptoms reported. Ongoing studies: Ongoing, current studies involve TBI patients who have been treated with tLED using either 26 J/cm2 per LED location on the head or treated with intranasal only (iLED) using red (633 nm) and NIR (810 nm) diodes placed into the nostrils. The NIR iLED is hypothesized to deliver photons to the hippocampus, and the red 633 nm iLED is believed to increase melatonin. Results have been similar to the previously published tLED study. Actigraphy sleep data showed increased time asleep (on average one additional hour per night) after the 18th tLED or iLED treatment. LED treatments may be performed in the home. Sham-controlled studies with veterans who have cognitive dysfunction from Gulf War Illness, blast TBI, and TBI/PTSD are currently ongoing. © Mary Ann Liebert, Inc.},

(The following abstract of the original article appeared in record [rid]2016-18089-008[/rid]). This exploratory study was designed to examine the neuropsychological effects of sports-related head trauma\textemdashspecifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n = 282), grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high-contact-sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low-contact sports (wrestling, soccer, baseball, judo, and basketball). This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high-contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: Pediatric head injuries occur commonly and are being reported in increasing numbers. Balance testing is a key component in the evaluation of suspected concussion, and the balance error scoring system (BESS) is likely the most well-known and widely used measure. To date, normative BESS scores for adults have been reported but not for children. Design: Normative data for BESS scores and modified BESS scores were created in a cohort of healthy children. Potential variables were analyzed as predictors of BESS performance. Setting: Local elementary and junior high schools. Participants: A total of 373 healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Assessment of Risk Factors: Gender, body mass index percentile, previous concussions, athletic participation, age, and the parental opinion of child's balance ability were examined as factors associated with the BESS score. Main Outcome Measures: BESS scores. Results: Normative data are reported, stratified by age groups of 5 to 7 years, 8 to 10 years, and 11 to 14 years of age, for both BESS and modified BESS. Median BESS scores are 23 for children aged 5 to 7, 18 for children aged 8 to 10, and 16 for children aged 11 to 14. Median modified BESS scores are 8 for children age 5 to 7, 5 for children age 8 to 10, and 4 for children age 11 to 14. Increasing age and positive parental opinion regarding their child's balance ability were independently correlated with decreasing BESS scores (P \< 0.01). Conclusions: The normative data on BESS scores for healthy children reported here provide age-stratified reference values for suspected balance alterations. © 2015 Wolters Kluwer Health, Inc.

In some cases, a trainer refers an athlete to a physician for definitive medical management. This study was conducted to determine the rate of agreement between athletic trainers and physicians regarding assessment of injuries in student athletes. All high school athletes who were injured between 2010 and 2012 at 5 regional high schools were included in a research database. All patients who were referred for physician evaluation and treatment were identified and included in this analysis. A total of 286 incidents met the inclusion criteria. A total of 263 (92%) of the athletic trainer assessments and physician diagnoses were in agreement. In the 23 cases of disagreement, fractures and sprains were the most common injuries. Kappa analysis showed the highest interrater agreement in injuries classified as dislocations and concussions and the lowest interrater agreement in meniscal/labral injuries and fractures. In the absence of a confirmed diagnosis, agreement among health care providers can be used to infer accuracy. According to this principle, as agreement between athletic trainers and physicians improves, there is a greater likelihood of arriving at the correct assessment and treatment plan. Athletic trainers are highly skilled professionals who are well trained in the evaluation of athletic injuries. The current study showed that additional training in identifying fractures may be beneficial to athletic trainers and the athletes they treat. [Orthopedics. 2016; 39(5):e944-e949.].

abstract = {Sports-related brain concussion is not well known despite its frequency. Few cases are reported. Brain concussion leads to an immediate transient alteration of the neurological functions followed by a post-concussion syndrome of variable duration. Due to the risk of neurodegenerative disease related to repeated concussion, we created a specialized outpatient clinic devoted to sports-related brain concussions in order to better apprehend the phenomenon, to search for factors predictive of unfavorable outcome, and most importantly to elaborate a protocol and a set of criteria for determining the moment the incriminated activity can be resumed under good conditions. The cohort included 211 athletes who attended the specialized outpatient clinic, 168 men and 43 women. The largest number of patients were rugby players (n = 166, 78.7%). Among the 211 athletes, 126 (59.7%) had already had one concussion and 132 attended the clinic twice, at most four days after the concussion. The diagnosis was considered on the playing field, generally because of the presence of amnesia or loss of consciousness. Among the 211 athletes, 106 (50.2%) left the field immediately after the concussion. For the post-concussion syndrome, headache was the most common functional sign (170/211, 80.6%). Age (\< 20 years), female gender, and recent history of a brain concussion were factors predictive of poor outcome as measured by the duration of the post-concussion syndrome and delay before returning to the sports activity. Loss of consciousness, anterograde or retrograde amnesia, and the number of episodes of prior brain concussion did not have any impact on the duration of the post-concussion syndrome and delay before returning to the sports activity. In our opinion, a specialized outpatient clinic visit less than four days after the concussion can help reduce the length of the post-concussion syndrome, mainly resulting from good patient education and better therapeutic management. © 2016},

Methods. Using a retrospective cohort design based on data from the Canadian Hospitals Injury Reporting and Prevention Program and the National Electronic Injury Surveillance System a comparison of injuries was made. Results. Trends in injuries were comparable. Proportions and odds of injuries were similar, except for a few exceptions. In Canada, more girls were injured and fractures were more prevalent. Compared with nonorganized football, organized football players were older, involved more males, and suffered more traumatic brain injuries and injuries to their lower extremities. Conclusion. Canadian and American youth football injuries were similar. The type of football, be it organized or nonorganized, has an impact on injuries. © 2016 The Author(s).},

abstract = {The collision accident in collegiate football game was simulated based on the game video and the concussive impact on the head was analyzed. First, the collision motion of players was reproduced based on the video by using motion analysis, and the translational and rotational velocities, relative position and contact location of the struck and the striking players' heads just before the collision were calculated. Then the data obtained were input to two helmeted finite element (FE) human head models as the initial condition, and the brain injury risk was evaluated by using the impact analysis. The FE helmet model was validated by a drop test of the helmet in which the head impactor was embedded. In the present study, two concussion suspected accident cases were analyzed; then the concussion was evaluated by ten mechanical parameters generated inside the skull caused by the collision. The injury risk evaluated by multi parameters belonged to the dangerous range that may cause concussion and was consistent with the diagnosis of the medical team doctor. The brain injury risk can be successfully estimated by the reconstructed simulation of the game video and FE analysis. To our knowledge, this study is the first attempt in Japan to estimate the brain injury risk systematically by a combination of game video analysis which is originally introduced for the players' health care and FE analysis by helmeted human head model. In the future, brain injury risk caused by an accident can be evaluated with higher accuracy by analyzing more accident cases. © 2016 The Japan Society of Mechanical Engineers.},

abstract = {Objective This study introduces a rapid picture naming test, the Mobile Universal Lexicon Evaluation System (MULES), as a novel, vision-based performance measure for concussion screening. The MULES is a visual-verbal task that includes 54 original photographs of fruits, objects and animals. We piloted MULES in a cohort of volunteers to determine feasibility, ranges of picture naming responses, and the relation of MULES time scores to those of King-Devick (K-D), a rapid number naming test. Methods A convenience sample (n = 20, age 34 ± 10) underwent MULES and K-D (spiral bound, iPad versions). Administration order was randomized; MULES tests were audio-recorded to provide objective data on temporal variability and ranges of picture naming responses. Results Scores for the best of two trials for all tests were 40\textendash50 s; average times required to name each MULES picture (0.72 ± 0.14 s) was greater than those needed for each K-D number ((spiral: 0.33 ± 0.05 s, iPad: 0.36 ± 0.06 s, 120 numbers), p \< 0.0001, paired t-test). MULES scores showed the greatest degree of improvement between trials (9.4 ± 4.8 s, p \< 0.0001 for trials 1 vs. 2), compared to K-D (spiral 1.5 ± 3.3 s, iPad 1.8 ± 3.4 s). Shorter MULES times demonstrated moderate and significant correlations with shorter iPad but not spiral K-D times (r = 0.49, p = 0.03). Conclusion The MULES test is a rapid picture naming task that may engage more extensive neural systems than more commonly used rapid number naming tasks. Rapid picture naming may require additional processing devoted to color perception, object identification, and categorization. Both tests rely on initiation and sequencing of saccadic eye movements. © 2016 Elsevier B.V.},

abstract = {Objective: Pediatric concussion is an extensive public health concern with a complex clinical presentation. Balance assessment has been well-studied in the adult population, but has been limited in children. We aimed to assess the reliability and minimum detectable change (MDC) of the Balance Error Scoring System (BESS) in healthy children. Design: This prospective observational study included 373 healthy children aged 5 to 14. Interrater reliability was assessed by having 4 assessors review videos of 50 random subjects distributed evenly by age and sex across the entire cohort. Intrarater reliability was performed by having assessors review videos of other assessors' live evaluations. Test-retest reliability was obtained by comparing BESS scores as recorded live at the 2 separate time points by the same rater. Setting: Local elementary and junior high schools. Participants: Three hundred and seventy three healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Main Outcome Measures: Intraclass Correlation Coefficients (ICCs) and MDC Scores. Results: The overall interrater ICC was determined to be 0.93 [95% confidence interval (CI), 0.79-0.97] and intrarater ICC was 0.96 (95% CI, 0.95-0.97) with individual intrarater ICCs ranging between 0.69 and 0.99. The test-retest reliability was 0.90 (95% CI, 0.88- 0.92). The MDCs were 9.6, 4.6, and 7.3 points at the 95% CIs for interrater, intrarater, and test-retest comparisons, respectively. No learning effect was seen. Conclusions: The BESS demonstrates excellent reliability in the pediatric population without evidence of a learning effect. © 2016 Wolters Kluwer Health, Inc.

Method: A sample of 4,809 adolescent student athletes was included, and subgroups with a history of treatment for headaches or a self-reported history of learning problems or attention-deficit hyperactivity disorder were analyzed separately. Exploratory principal axis factor analyses with Promax rotations were used. Results: As hypothesized, both the combination of Verbal Memory and Visual Memory Composite scores loaded on one (Memory) factor, while Visual Motor Speed and Reaction Time loaded on a different (Speed) factor, in the total sample and in all subgroups. Conclusion: These results provide reasonably compelling evidence, across multiple samples, which ImPACT® measures 2 distinct factors: memory and speed. [ABSTRACT FROM AUTHOR]},

abstract = {Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12\textendash19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players. [ABSTRACT FROM AUTHOR]},

abstract = {The aim of this study was to evaluate longitudinal changes in the diffusion characteristics of brain white matter (WM) in collegiate athletes at three time points: prior to the start of the football season (T1), after one season of football (T2), followed by six months of no-contact rest (T3). Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints. Average diffusion values were obtained from statistically significant clusters for each individual. No athlete suffered a concussion during the study period. After one season of play (T1 to T2), we observed a significant increase in trace in a cluster located in the brainstem and left temporal lobe, and a significant increase in FA in the left parietal lobe. After six months of no-contact rest (T2 to T3), there was a significant decrease in trace and FA in clusters that were partially overlapping or in close proximity with the initial clusters (T1 to T2), with no significant changes from T1 to T3. Repetitive head impacts (RHI) sustained during a single football season may result in alterations of the brain’s WM in collegiate football players. These changes appear to return to baseline after 6 months of no-contact rest, suggesting remission of WM alterations. Our preliminary results suggest that collegiate football players might benefit from periods without exposure to RHI. (PsycINFO Database Record (c) 2017 APA, all rights reserved)},

abstract = {Background: Epidemiological studies suggest that the athletic population has a significant need for vision care. Recently, there has been an increased awareness and discussion of sports-related concussion, which can have a negative impact on athletic performance. The goal of this investigation is to characterize baseline performance of a cohort of elite athletes on a battery of sports vision tests. This information can: 1) serve as a baseline for comparison after an athlete is concussed, 2) help evaluate the effects of concussion on the visual system as it relates to athletic performance, and 3) help establish vision-related criteria for determining if and when an athlete is ready to return to play and perform at pre-concussive levels. Methods: Twenty-one male Major League Soccer athletes ages 18-35 were tested on 20 sports vision-related tests. Results: Eighteen of 21 subjects (86%) demonstrated one or more clinically significant problems with visual acuity, ocular health, binocular vision, and/or exhibited visual symptoms. The screening results indicate that 17% failed visual acuity, 26% displayed abnormal ocular health findings, 6% exhibited binocular vision problems, and 29% complained of at least one visual symptom related to a previous incident involving head trauma or concussion. Conclusion: This visual performance testing characterized baseline findings for this population and may help determine how deficits may interfere with optimum athletic performance at the elite level. The baseline testing could also serve as an indicator of recovery in acute vs. chronic stages and help determine if and when a concussed athlete is ready to return to play.

abstract = {Surrogate model-based multi-objective design optimization was performed to reduce concussion risk during frontal football helmet impacts. In particular, a topological decomposition of the football helmet facemask was performed to formulate the design problem, and brain injury metrics were exploited as objective functions. A validated finite element model of a helmeted human head was used to recreate facemask impacts. Due to the prohibitive computational expense of the full scale simulations, a surrogate modeling approach was employed. An optimal surrogate model selection framework, called Concurrent Surrogate Model Selection, or COSMOS, was utilized to identify the surrogate models best suited to approximate each objective function. The resulting surrogate models were implemented in the Non-dominated Sorting Genetic Algorithm II (NSGA-II) optimization algorithm. Constraints were implemented to control the solid material fraction in the facemask design space, and binary variables were used to control the placement of the facemask bars. The optimized facemask designs reduced the maximum tensile pressure in the brain by 7.5% and the maximum shear strain by a remarkable 39.5%. This research represents a first-of-its-kind approach to multi-objective design optimization on a football helmet, and demonstrates the possibilities that are achievable in improving human safety by using such a simulation-based design optimization. © 2016 Elsevier Ltd},

abstract = {Objective: The objective of this paper is to review existing literature surrounding the utility of the King-Devick test which is a commonly used sideline assessment tool for sport-related concussions. Methods: A review of the literature was performed using MEDLINE, CINHAL, and SportDiscus databases. The search was performed from the beginning of the record through November 16th, 2015. Results: This search strategy yielded 27 articles from aforementioned databases. Further searching in The Cochrane Library with King-Devick AND Concuss* search terms yielded one additional article, summing a total of 28 articles. After removal of duplicates and implementation of the inclusion/exclusion criteria, 8 articles for extensively reviewed. Conclusion: This narrative review suggests that the King-Devick test is an efficient sideline assessment tool for sport-related concussions. However, we recommend that the King-Devick should be used as a sideline screening tool, not a concussion diagnosis tool at this time. A proper baseline time including multiple tests may be recommended to negate the learning affect and to have a reliable baseline in which to measure from for future reference. A three second difference appears appropriate to identify the possibility of concussion and to remove an athlete from play. At this time, the athlete should be monitored and further evaluated as symptoms are sometimes delayed. We suggest that further research may be useful to better determine the efficacy of the K-D test in detecting concussions across a broader range of athletes and sports. We also suggest further research may investigate the K-D test a potential return-to-play tool for clinicians and medical personnel.},

However, modified headgear studies have demonstrated that significant improvements in impact energy attenuation performance are possible with small design changes, such as increases in foam density and thickness. A literature review of the design, performance and use of headgear in Australian football, rugby league and rugby union was conducted. A total of 23 articles were identified using primary and secondary search strategies, which included epidemiological field studies, laboratory impact test studies and studies investigating the behaviours and attitudes of players. The results of the review were synthesised and used to identify injury reduction objectives and appropriate design criteria. The need for a headgear standard was identified and performance requirements were discussed, which drew upon human tolerance and sports-specific head impact exposure data. Usability and behavioural issues, which require consideration during the design process, were also assessed. © IMechE 2015.},

Despite this increased interest, there remains limited knowledge about the potential influence of significant others (e.g, parents, coaches, and teammates) on young athletes concerning the Return to Play (RTP) process following a concussion. The purpose of this exploratory study was to examine the perceived social influences on female youth ice hockey players’ RTP following a concussion. Using a phenomenological approach, five female competitive youth ice hockey players (Mage = 12.2) were interviewed to gain insight into their experiences during the RTP process. Coaches, teammates, parents, siblings, and teachers were found to play a significant role in RTP. With regards to influences from others, four common themes emerged: Compassion, Support, Protection and Pressure. Study findings support the importance of concussion management education systems for coaches, parents, and athletes. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: We review the general topic of traumatic brain injury (TBI) and our research utilizing transcranial photobiomodulation (tPBM) to improve cognition in chronic TBI using red/near-infrared (NIR) light-emitting diodes (LEDs) to deliver light to the head. tPBM improves mitochondrial function increasing oxygen consumption, production of adenosine triphosphate (ATP), and improving cellular energy stores. Nitric oxide is released from the cells increasing regional blood flow in the brain. Review of published studies: In our previously published study, 11 chronic TBI patients with closed-head TBI caused by different accidents (motor vehicle accident, sports-related, improvised explosive device blast injury) and exhibiting long-lasting cognitive dysfunction received 18 outpatient treatments (Monday, Wednesday, Friday for 6 weeks) starting at 10 months to 8 years post-TBI. LED therapy is nonthermal, painless, and noninvasive. An LED-based device classified as nonsignificant risk (FDA cleared) was used. Each LED cluster head (5.35 cm diameter, 500mW, 22.2 mW/cm2) was applied for 9 min 45 sec (13 J/cm2) using 11 locations on the scalp: midline from front-to-back hairline and bilaterally on frontal, parietal, and temporal areas. Testing was performed before and after transcranial LED (tLED; at 1 week, 1 month, and at 2 months after the 18th treatment) and showed significant improvements in executive function and verbal memory. There were also fewer post-traumatic stress disorder (PTSD) symptoms reported. Ongoing studies: Ongoing, current studies involve TBI patients who have been treated with tLED using either 26 J/cm2 per LED location on the head or treated with intranasal only (iLED) using red (633 nm) and NIR (810 nm) diodes placed into the nostrils. The NIR iLED is hypothesized to deliver photons to the hippocampus, and the red 633 nm iLED is believed to increase melatonin. Results have been similar to the previously published tLED study. Actigraphy sleep data showed increased time asleep (on average one additional hour per night) after the 18th tLED or iLED treatment. LED treatments may be performed in the home. Sham-controlled studies with veterans who have cognitive dysfunction from Gulf War Illness, blast TBI, and TBI/PTSD are currently ongoing. © Mary Ann Liebert, Inc.},

This exploratory study was designed to examine the neuropsychological effects of sports-related head trauma\textemdashspecifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n = 282), grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high-contact-sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low-contact sports (wrestling, soccer, baseball, judo, and basketball). This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high-contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Objective: Pediatric head injuries occur commonly and are being reported in increasing numbers. Balance testing is a key component in the evaluation of suspected concussion, and the balance error scoring system (BESS) is likely the most well-known and widely used measure. To date, normative BESS scores for adults have been reported but not for children. Design: Normative data for BESS scores and modified BESS scores were created in a cohort of healthy children. Potential variables were analyzed as predictors of BESS performance. Setting: Local elementary and junior high schools. Participants: A total of 373 healthy children between the ages of 5 and 14. Interventions: The BESS was performed on all children. Assessment of Risk Factors: Gender, body mass index percentile, previous concussions, athletic participation, age, and the parental opinion of child's balance ability were examined as factors associated with the BESS score. Main Outcome Measures: BESS scores. Results: Normative data are reported, stratified by age groups of 5 to 7 years, 8 to 10 years, and 11 to 14 years of age, for both BESS and modified BESS. Median BESS scores are 23 for children aged 5 to 7, 18 for children aged 8 to 10, and 16 for children aged 11 to 14. Median modified BESS scores are 8 for children age 5 to 7, 5 for children age 8 to 10, and 4 for children age 11 to 14. Increasing age and positive parental opinion regarding their child's balance ability were independently correlated with decreasing BESS scores (P \< 0.01). Conclusions: The normative data on BESS scores for healthy children reported here provide age-stratified reference values for suspected balance alterations. © 2015 Wolters Kluwer Health, Inc.

abstract = {It is standard practice in high school athletic programs for certified athletic trainers to evaluate and treat injured student athletes. In some cases, a trainer refers an athlete to a physician for definitive medical management. This study was conducted to determine the rate of agreement between athletic trainers and physicians regarding assessment of injuries in student athletes. All high school athletes who were injured between 2010 and 2012 at 5 regional high schools were included in a research database. All patients who were referred for physician evaluation and treatment were identified and included in this analysis. A total of 286 incidents met the inclusion criteria. A total of 263 (92%) of the athletic trainer assessments and physician diagnoses were in agreement. In the 23 cases of disagreement, fractures and sprains were the most common injuries. Kappa analysis showed the highest interrater agreement in injuries classified as dislocations and concussions and the lowest interrater agreement in meniscal/labral injuries and fractures. In the absence of a confirmed diagnosis, agreement among health care providers can be used to infer accuracy. According to this principle, as agreement between athletic trainers and physicians improves, there is a greater likelihood of arriving at the correct assessment and treatment plan. Athletic trainers are highly skilled professionals who are well trained in the evaluation of athletic injuries. The current study showed that additional training in identifying fractures may be beneficial to athletic trainers and the athletes they treat. [Orthopedics. 2016; 39(5):e944-e949.].

abstract = {Sports-related brain concussion is not well known despite its frequency. Few cases are reported. Brain concussion leads to an immediate transient alteration of the neurological functions followed by a post-concussion syndrome of variable duration. Due to the risk of neurodegenerative disease related to repeated concussion, we created a specialized outpatient clinic devoted to sports-related brain concussions in order to better apprehend the phenomenon, to search for factors predictive of unfavorable outcome, and most importantly to elaborate a protocol and a set of criteria for determining the moment the incriminated activity can be resumed under good conditions. The cohort included 211 athletes who attended the specialized outpatient clinic, 168 men and 43 women. The largest number of patients were rugby players (n = 166, 78.7%). Among the 211 athletes, 126 (59.7%) had already had one concussion and 132 attended the clinic twice, at most four days after the concussion. The diagnosis was considered on the playing field, generally because of the presence of amnesia or loss of consciousness. Among the 211 athletes, 106 (50.2%) left the field immediately after the concussion. For the post-concussion syndrome, headache was the most common functional sign (170/211, 80.6%). Age (\< 20 years), female gender, and recent history of a brain concussion were factors predictive of poor outcome as measured by the duration of the post-concussion syndrome and delay before returning to the sports activity. Loss of consciousness, anterograde or retrograde amnesia, and the number of episodes of prior brain concussion did not have any impact on the duration of the post-concussion syndrome and delay before returning to the sports activity. In our opinion, a specialized outpatient clinic visit less than four days after the concussion can help reduce the length of the post-concussion syndrome, mainly resulting from good patient education and better therapeutic management. © 2016},

The objectives of this study were (a) to contrast the injuries in Canadian and American football players aged 6 to 17 years and (b) compare the injuries sustained during organized football with those in nonorganized football. Methods. Using a retrospective cohort design based on data from the Canadian Hospitals Injury Reporting and Prevention Program and the National Electronic Injury Surveillance System a comparison of injuries was made. Results. Trends in injuries were comparable. Proportions and odds of injuries were similar, except for a few exceptions. In Canada, more girls were injured and fractures were more prevalent. Compared with nonorganized football, organized football players were older, involved more males, and suffered more traumatic brain injuries and injuries to their lower extremities. Conclusion. Canadian and American youth football injuries were similar. The type of football, be it organized or nonorganized, has an impact on injuries. © 2016 The Author(s).},

abstract = {The collision accident in collegiate football game was simulated based on the game video and the concussive impact on the head was analyzed. First, the collision motion of players was reproduced based on the video by using motion analysis, and the translational and rotational velocities, relative position and contact location of the struck and the striking players' heads just before the collision were calculated. Then the data obtained were input to two helmeted finite element (FE) human head models as the initial condition, and the brain injury risk was evaluated by using the impact analysis. The FE helmet model was validated by a drop test of the helmet in which the head impactor was embedded. In the present study, two concussion suspected accident cases were analyzed; then the concussion was evaluated by ten mechanical parameters generated inside the skull caused by the collision. The injury risk evaluated by multi parameters belonged to the dangerous range that may cause concussion and was consistent with the diagnosis of the medical team doctor. The brain injury risk can be successfully estimated by the reconstructed simulation of the game video and FE analysis. To our knowledge, this study is the first attempt in Japan to estimate the brain injury risk systematically by a combination of game video analysis which is originally introduced for the players' health care and FE analysis by helmeted human head model. In the future, brain injury risk caused by an accident can be evaluated with higher accuracy by analyzing more accident cases. © 2016 The Japan Society of Mechanical Engineers.},

Methods: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Results: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p \< 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores. Conclusions: Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities. © 2015 S.

abstract = {Purpose: Approximately 90% of concussions are transient, with symptoms resolving within 10\textendash14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. Methods: We conducted a retrospective study of 52 pediatric patients with persistent post-concussion symptoms after 3 months. We collected demographics and neuroimaging results obtained greater than 2 weeks post-concussion. Neuroimaging ordered in the first 2 weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. Results: Of 52 patients with PCS, 23/52 (44 %) had neuroimaging at least 2 weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3 %), 1/8 CTs (13 %), and 0/5 x-rays (0 %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric patients totaled $129,025. We estimate the cost to identify a single positive finding was $21,000 for head CT and $104,500 for brain MRI. Conclusions: In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase. © 2015, Springer-Verlag Berlin Heidelberg.},

abstract = {Emerging research on the long-term impact of concussions on athletes has allowed public recognition of the potentially devastating effects of these and other mild head injuries. Mild traumatic brain injury (mTBI) is a multifaceted disease for which management remains a clinical challenge. Recent pre-clinical and clinical data strongly suggest a destructive synergism between brain temperature elevation and mTBI; conversely, brain hypothermia, with its broader, pleiotropic effects, represents the most potent neuro-protectant in laboratory studies to date. Although well-established in selected clinical conditions, a systemic approach to accomplish regional hypothermia has failed to yield an effective treatment strategy in traumatic brain injury (TBI). Furthermore, although systemic hypothermia remains a potentially valid treatment strategy for moderate to severe TBIs, it is neither practical nor safe for mTBIs. Therefore, selective head-neck cooling may represent an ideal strategy to provide therapeutic benefits to the brain. Optimizing brain temperature management using a National Aeronautics and Space Administration (NASA) spacesuit spinoff head-neck cooling technology before and/or after mTBI in contact sports may represent a sensible, practical, and effective method to potentially enhance recover and minimize post-injury deficits. In this paper, we discuss and summarize the anatomical, physiological, preclinical, and clinical data concerning NASA spinoff head-neck cooling technology as a potential treatment for mTBIs, particularly in the context of contact sports. © 2015 Huan Wang et al., licensee De Gruyter Open.},

abstract = {OBJECT: The objectives of this study were twofold: (1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and (2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population. METHODS: The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized. RESULTS: One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1-8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes. Interventions for patients with postinjury psychiatric outcomes included pharmacological therapy alone in 2 patients (10%), cognitive behavioral therapy alone in 4 (20%), multimodal therapy in 9 (45%), and no treatment in 5 (25%). Overall, 5 (25%) of the patients with postinjury psychiatric disorders were medically cleared to return to full sports participation, whereas 5 (25%) were lost to follow-up and 9 (45%) remained in treatment by the multidisciplinary concussion program at the end of the study period. One patient who was asymptomatic at the time of initial consultation committed suicide. CONCLUSIONS: Emotional symptoms were commonly reported among pediatric patients with SRC referred to a multidisciplinary pediatric concussion program. In some cases, these symptoms contributed to the development of an NPD, isolated suicidal ideation, and worsening symptoms of a preexisting psychiatric disorder. Future research is needed to clarify the prevalence, pathophysiology, risk factors, and evidence-based management of postinjury psychiatric outcomes after pediatric SRC. Successful management of these patients requires prompt recognition and multidisciplinary care by experts with clinical training and experience in concussion and psychiatry.},

abstract = {Biomechanical studies of concussions have progressed from qualitative observations of head impacts to physical and numerical reconstructions, direct impact measurements, and finite element analyses. Supplementary to a previous study, which investigated maximum principal strain, the current study used a detailed finite element head model to simulate unhelmeted concussion and no-injury head impacts and evaluate the effectiveness of various tissue-level brain injury predictors: strain rate, product of strain and strain rate, cumulative strain damage measure, von Mises stress, and intracranial pressure. Von Mises stress was found to be the most effective predictor of concussion. It was also found that the thalamus and corpus callosum were brain regions with strong associations with concussion. Tentative tolerance limits for tissue-level predictors were proposed in an attempt to broaden the understanding of unhelmeted concussions. For the thalamus, tolerance limits were proposed for a 50% likelihood of concussion: 2.24 kPa, 24.0 s-1, and 2.49 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. For the corpus callosum, tolerance limits were proposed for a 50% likelihood of concussion: 3.51 kPa, 25.1 s-1, and 2.76 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. © 2015 Human Kinetics, Inc.},

Risk factors associated with chronic traumatic encephalopathy include playing contact sports, presence of the apolipoprotein E4, and old age. Although it shares certain histopathological findings with Alzheimer disease, chronic traumatic encephalopathy has a more specific presentation (hyperphosphorylated tau protein deposited as neurofibrillary tangles, associated with neuropil threads and sometimes with beta-amyloid plaques). Its clinical presentation is insidious; patients show mild cognitive and emotional symptoms before progressing to parkinsonian motor signs and finally dementia. Results from new experimental diagnostic tools are promising, but these tools are not yet available. The mainstay of managing this disease is prevention and early detection of its first symptoms. © 2014 Sociedad Espa\~{n}ola de Neurologi´a.},
