abstract = {The National Rugby League (NRL) in Australia introduced a new 'concussion interchange rule' (CIR) in 2014, whereby a player suspected of having sustained a concussion can be removed from play, and assessed, without an interchange being tallied against the player's team. We conducted a video analysis, describing player and injury characteristics, situational factors, concussion signs, and return to play for each "CIR" event for the 2014 season. There were 167 reported uses of the CIR. Apparent loss of consciousness/unresponsiveness was observed in 32% of cases, loss of muscle tone in 54%, clutching the head in 70%, unsteadiness of gait in 66%, and a vacant stare in 66%. More than half of the players who were removed under the CIR returned to play later in the same match (57%). Most incidences occurred from a hit up (62%) and occurred during a tackle where the initial contact was with the upper body (80%). The new concussion interchange rule has been used frequently during the first season of its implementation. In many cases, there appeared to be video evidence of injury but the athlete was cleared to return to play. More research is needed on the usefulness of video review for identifying signs of concussive injury. Copyright © Georg Thieme Verlag KG Stuttgart . New York.},

abstract = {CONTEXT: Epidemiologic studies have identified differences in concussion incidence between the sexes. However, few authors to date have updated injury rates (IRs) and time loss between male and female concussed athletes. OBJECTIVE: To examine sex differences in IRs and time loss in concussed National Collegiate Athletic Association (NCAA) athletes. DESIGN: Descriptive epidemiologic study. SETTING: National Collegiate Athletic Association athletics. PATIENTS OR OTHER PARTICIPANTS: A total of 1702 concusssed NCAA athletes, consisting of 903 females and 779 males participating in soccer, basketball, ice hockey, lacrosse, softball, or baseball over a 5-year period from 2004-2005 through 2008-2009. MAIN OUTCOME MEASURE(S): Using the NCAA Injury Surveillance Program, athletic trainers reported concussions, athlete-exposures (AEs), and time loss across 10 NCAA sports. An IR is the number of injuries in a particular category divided by the number of AEs in that category. RESULTS: During the study period, 1702 concussions were reported during 4 170 427 AEs for an overall total of 5.47 per 10 000 AEs. In sex-comparable sports, females had a 1.4 times higher overall concussion IR than males (IRs = 4.84 and 3.46, respectively), with greater rates in women's baseball/softball, basketball, ice hockey, and soccer than men. Female soccer and basketball players also displayed more time loss after concussion compared with male basketball and soccer players. CONCLUSIONS: Female athletes sustained a higher rate of concussion and, in all sports except lacrosse, had greater time loss from concussion than male athletes. Additional research is needed on sex differences in time loss after concussions.},

abstract = {A systematic review of rugby union and league injuries among players under the age of 21 years was carried out to calculate probabilities of match injury for a player over a season and a pooled estimate of match injury incidence where studies were sufficiently similar. The probability of a player being injured over a season ranged from 6% to 90% for rugby union and 68% to 96% for rugby league. The pooled injury incidence estimate for rugby union was 26.7/1000 player-hours for injuries irrespective of need for medical attention or time-loss and 10.3/1000 player-hours for injuries requiring at least 7 days absence from games; equivalent to a 28.4% and 12.1% risk of being injured over a season. Study heterogeneity contributed to a wide variation in injury incidence. Public injury surveillance and prevention systems have been successful in reducing injury rates in other countries.

abstract = {Background: The apolipoprotein E gene (APOE) has emerged as a candidate for prognosticating traumatic brain injury (TBI) recovery, with APOE$epsilon$4 identified as a susceptibility marker for poor outcome, despite large discrepancy in its reported influence post-TBI.Methods: A systematic review was conducted, including all primary articles investigating the role of APOE$epsilon$4 on TBI outcome. A total of 65 studies were included, including 24 predominantly investigating mild (mTBI), seven moderate (modTBI) and 33 severe (sTBI); severity was not reported in one study.Results: In mTBI studies, the association between APOE$epsilon$4 and post-TBI outcome was concluded as non-contributory in 14 studies (58.3%), hazardous in nine (37.5%) and protective in one (4.2%). In sTBI studies, the role of APOE$epsilon$4 was hazardous in 21 (63.6%), non-contributory in nine (27.3%) and protective in three (9.1%). Of the seven studies investigating dementia outcomes, four observed a hazardous association with APOE$epsilon$4, while three reported no association. Six studies examined Alzheimers dementia pathology, of which three reported a hazardous influence of APOE$epsilon$4.Conclusions: The influence of APOE$epsilon$4 on neuropsychological testing, functional outcome and in paediatric populations was incongruous. This review supports the majority of research indicating APOE$epsilon$4 adversely influences recovery following TBI, particularly with respect to dementia-related outcomes and outcomes following sTBI. © 2015 Taylor \& Francis Group, LLC.},

abstract = {BACKGROUND: While there is concern regarding head, face, and eye injuries in field hockey, prompting some to recommend the use of protective equipment such as goggles and helmets, little has been written about their incidence and mechanism of injury in the modern game of field hockey. The elucidation of this information will better inform the development of maximally effective injury prevention schemes to protect the athlete while maintaining the integrity of the game. PURPOSE: To determine the incidence and epidemiology of head, face, and eye injuries in United States collegiate women's field hockey players from 2004-2005 to 2008-2009. STUDY DESIGN: Descriptive epidemiological study. METHODS: All head, face, and eye injuries reported to the National Collegiate Athletic Association Injury Surveillance System for collegiate women's field hockey athletes from the 2004-2005 through 2008-2009 seasons were analyzed. Data regarding the event type, injury mechanism, body part injured, type of injury, outcome, and time lost were reviewed. The weighted injury incidence per 1000 athlete-exposures (AEs) was calculated using the exposure data set for the same years; 95% CIs were calculated based on a normal approximation to the Poisson distribution. RESULTS: There were 150 reported traumatic injuries during this time period, with a weighted occurrence of 1587.3 injuries. The overall incidence of head, face, and eye injuries in collegiate women's field hockey was 0.94 per 1000 AEs (95% CI, 0.86-1.19). Injuries to the head or face, other than the mouth, nose, and eye, accounted for 75.3% of these injuries. The incidence of eye injuries was 0.07 per 1000 AEs (95% CI, 0.03-0.12); nose injuries occurred at a rate of 0.10 per 1000 AEs (95% CI, 0.05-0.15). The rate of traumatic dental injuries was 0.06 per 1000 AEs (95% CI, 0.04-0.14). Contact with an apparatus caused 72.9% of all injuries; specifically, contact with an elevated ball accounted for 47.9% of all injuries, and contact with an elevated stick caused 21.7% of all injuries. While the majority of players suffering a head, face, or eye injury were able to return to sport that season (90.0%), the remaining athletes suffered season-ending injuries (10%). Concussions accounted for 42.8% of all head, face, and eye injuries reported (0.40 per 1000 AEs; 95% CI, 0.32-0.53). CONCLUSION: Head, face, and eye injuries occur regularly in women's field hockey. This description of the injury profile and mechanisms of injury may be used to design appropriate injury prevention schemes for the sport.Copyright © 2015 The Author(s).},

abstract = {BACKGROUND: The National Collegiate Athletic Association (NCAA) has recently highlighted mental health concerns in student athletes, though the incidence of suicide among NCAA athletes is unclear. The purpose of this study was to determine the rate of suicide among NCAA athletes. HYPOTHESIS: The incidence of suicide in NCAA athletes differs by sex, race, sport, and division. STUDY DESIGN: Retrospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: NCAA Memorial Resolutions list and published NCAA demographic data were used to identify student-athlete deaths and total participant seasons from 2003-2004 through 2011-2012. Deaths were analyzed by age, sex, race, division, and sport. RESULTS: Over the 9-year study period, 35 cases of suicide were identified from a review of 477 student-athlete deaths during 3,773,309 individual participant seasons. The overall suicide rate was 0.93/100,000 per year. Suicide represented 7.3% (35/477) of all-cause mortality among NCAA student athletes. The annual incidence of suicide in male athletes was 1.35/100,000 and in female athletes was 0.37/100,000 (relative risk [RR], 3.7; P \< 0.01). The incidence in African American athletes was 1.22/100,000 and in white athletes was 0.87/100,000 (RR, 1.4; P = 0.45). The highest rate of suicide occurred in men's football (2.25/100,000), and football athletes had a relative risk of 2.2 (P = 0.03) of committing suicide compared with other male, nonfootball athletes. CONCLUSION: The suicide rate in NCAA athletes appears to be lower than that of the general and collegiate population of similar age. NCAA male athletes have a significantly higher rate of suicide compared with female athletes, and football athletes appear to be at greatest risk. CLINICAL RELEVANCE: Suicide represents a preventable cause of death, and development of effective prevention programs is recommended. Copyright © 2015 The Author(s).},

abstract = {Objectives To identify the circumstances in which international rugby players exit the playing area during match activities and to define a safe run-off distance around the playing area. Method An observational study using video recordings of 102 matches associated with the Rugby World Cup (2011), Rugby Championship (2013, 2014) and Six Nations Championship (2013, 2014) were used to analyse every event in which one or more players exited the playing area during normal match activities. The circumstances in which a player exited the playing area were categorised using a range of parameters: playing position, location, out-of-play region, match activity, distance travelled over the touchline, contacts made with pitchside fixtures and fittings. Results Ninety-five per cent of player-excursions took place within 5.2 m of the touchline. Players exiting the playing area were nearly three times more likely to be a back than a forward (p\<0.001) and the event was more likely to take place when a team was defending than attacking (p\<0.001). Being forced out of play during a contact event (70%) was the major reason for players exiting the playing area. Most players (88%) exiting the playing area only made contact with the perimeter area surface; a small proportion of players contacted touchline flags (6.1%), advertising boards (2.3%) and TV cameras/equipment (1.0%). Conclusions A minimum hazard-free distance of 5 m around a Rugby pitch is proposed based on the 95% percentile frequency distribution of player-excursion events into the areas contiguous with the playing area. © 2015 BMJ Publishing Group.

Loss of consciousness was observed in 30% of cases. Common observable signs of injury included clutching of the head, balance problems or wobbly legs and a blank or vacant state. There were no post-concussive seizures. All players with loss of consciousness were removed from play. However, only half of the total sample was removed from play and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned the following week. Illegal play accounted for 25% of all concussions.Conclusions: Video analysis may be a useful method to study the incidence, mechanism and management of concussion in sports such as Rugby League. Future studies may include larger numbers to validate this preliminary data and may also investigate other levels of play and age ranges. © 2015 Taylor and Francis Group, LLC.},

abstract = {Background: Since their conception during the mid-1970s, international participation in extreme sports has grown rapidly. The recent death of extreme snowmobiler Caleb Moore at the 2013 Winter X Games has demonstrated the serious risks associated with these sports. Purpose: To examine the incidence and prevalence of head and neck injuries (HNIs) in extreme sports. Study Design: Descriptive epidemiological study. Methods: The National Electronic Injury Surveillance System (NEISS) was used to acquire data from 7 sports (2000-2011) that were included in the Winter and Summer X Games. Data from the NEISS database were collected for each individual sport per year and type of HNI. Cumulative data for overall incidence and injuries over the entire 11-year period were calculated. National estimates were determined using NEISS-weighted calculations. Incidence rates were calculated for extreme sports using data from Outdoor Foundation Participation Reports. Results: Over 4 million injuries were reported between 2000 and 2011, of which 11.3% were HNIs. Of all HNIs, 83% were head injuries and 17% neck injuries. The 4 sports with the highest total incidence of HNI were skateboarding (129,600), snowboarding (97,527), skiing (83,313), and motocross (78,236). Severe HNI (cervical or skull fracture) accounted for 2.5% of extreme sports HNIs. Of these, skateboarding had the highest percentage of severe HNIs. Conclusion: The number of serious injuries suffered in extreme sports has increased as participation in the sports continues to grow. A greater awareness of the dangers associated with these sports offers an opportunity for sports medicine and orthopaedic physicians to advocate for safer equipment, improved on-site medical care, and further research regarding extreme sports injuries. © 2015 The Author(s).},

abstract = {Purpose of Review: Growing public health concern exists over the incidence of chronic traumatic brain injury (TBI) in athletes participating in contact sports. Chronic TBI represents a spectrum of disorders associated with long-term consequences of single or repetitive TBI and includes chronic traumatic encephalopathy (CTE), chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologists should be familiar with the different types of chronic TBI and their diagnostic criteria. Recent Findings: CTE is the most severe chronic TBI and represents the neurologic consequences of repetitive mild TBI. It is particularly noted among boxers and football players. CTE presents with behavioral, cognitive, and motor symptoms, and can only be definitively diagnosed postmortem. Chronic postconcussion syndrome is defined as postconcussion symptoms that last longer than 1 year and do not appear to resolve; it may develop after a single concussive event. Chronic neurocognitive impairment is an all-encompassing clinical term denoting long-term neurologic sequelae secondary to sports-related trauma and can present either within the postconcussion syndrome or years after a symptom-free interval. Summary: This article discusses the diagnostic evaluation of chronic TBI, including clinical history, neurologic examination, neuropsychological testing, neuroimaging, and laboratory testing, as well as the distinctions between CTE, chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologic impairment among athletes exposed to repetitive brain injury appears to be a real phenomenon. Because CTE has no established treatment, prevention is of paramount importance for athletes participating in contact sports. © 2014, American Academy of Neurology.},

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

abstract = {OBJECTIVE: Childhood bicycle-related head injuries can be prevented through the use of helmets. Although helmet legislation has proved to be a successful strategy for the adoption of helmets, its effect on the rates of head injury is uncertain. In Canada, 4 provinces have such legislation. The objective of this study was to measure the impact of helmet legislation on bicycle-related head injuries in Canadian children. METHODS: Routinely collected data from the Canadian Institute for Health Information identified all Canadian children (5-19 years) who were hospitalized for bicycling-related injuries from 1994-1998. Children were categorized as head or other injury on the basis of International Classification of Diseases, Ninth Revision, codes. Rates of head injuries and other injuries were compared over time in provinces that adopted legislation and those that did not. RESULTS: Of the 9650 children who were hospitalized because of a bicycle-related injury, 3426 sustained injuries to the head and face and the remaining 6224 had other injuries. The bicycle-related head injury rate declined significantly (45% reduction) in provinces where legislation had been adopted compared with provinces and territories that did not adopt legislation (27% reduction). CONCLUSION: This country-wide study compared rates of head injury in regions with and without mandatory helmet legislation. Comparing head injuries with other non-head-injured children controlled for potential differences in children's cycling habits. The strong protective association between helmet legislation and head injuries supports the adoption of helmet legislation as an effective tool in the prevention of childhood bicycle-related head injuries.},

abstract = {The National Rugby League (NRL) in Australia introduced a new 'concussion interchange rule' (CIR) in 2014, whereby a player suspected of having sustained a concussion can be removed from play, and assessed, without an interchange being tallied against the player's team. We conducted a video analysis, describing player and injury characteristics, situational factors, concussion signs, and return to play for each "CIR" event for the 2014 season. There were 167 reported uses of the CIR. Apparent loss of consciousness/unresponsiveness was observed in 32% of cases, loss of muscle tone in 54%, clutching the head in 70%, unsteadiness of gait in 66%, and a vacant stare in 66%. More than half of the players who were removed under the CIR returned to play later in the same match (57%). Most incidences occurred from a hit up (62%) and occurred during a tackle where the initial contact was with the upper body (80%). The new concussion interchange rule has been used frequently during the first season of its implementation. In many cases, there appeared to be video evidence of injury but the athlete was cleared to return to play. More research is needed on the usefulness of video review for identifying signs of concussive injury. Copyright © Georg Thieme Verlag KG Stuttgart . New York.},

abstract = {CONTEXT: Epidemiologic studies have identified differences in concussion incidence between the sexes. However, few authors to date have updated injury rates (IRs) and time loss between male and female concussed athletes. OBJECTIVE: To examine sex differences in IRs and time loss in concussed National Collegiate Athletic Association (NCAA) athletes. DESIGN: Descriptive epidemiologic study. SETTING: National Collegiate Athletic Association athletics. PATIENTS OR OTHER PARTICIPANTS: A total of 1702 concusssed NCAA athletes, consisting of 903 females and 779 males participating in soccer, basketball, ice hockey, lacrosse, softball, or baseball over a 5-year period from 2004-2005 through 2008-2009. MAIN OUTCOME MEASURE(S): Using the NCAA Injury Surveillance Program, athletic trainers reported concussions, athlete-exposures (AEs), and time loss across 10 NCAA sports. An IR is the number of injuries in a particular category divided by the number of AEs in that category. RESULTS: During the study period, 1702 concussions were reported during 4 170 427 AEs for an overall total of 5.47 per 10 000 AEs. In sex-comparable sports, females had a 1.4 times higher overall concussion IR than males (IRs = 4.84 and 3.46, respectively), with greater rates in women's baseball/softball, basketball, ice hockey, and soccer than men. Female soccer and basketball players also displayed more time loss after concussion compared with male basketball and soccer players. CONCLUSIONS: Female athletes sustained a higher rate of concussion and, in all sports except lacrosse, had greater time loss from concussion than male athletes. Additional research is needed on sex differences in time loss after concussions.},

abstract = {A systematic review of rugby union and league injuries among players under the age of 21 years was carried out to calculate probabilities of match injury for a player over a season and a pooled estimate of match injury incidence where studies were sufficiently similar. The probability of a player being injured over a season ranged from 6% to 90% for rugby union and 68% to 96% for rugby league. The pooled injury incidence estimate for rugby union was 26.7/1000 player-hours for injuries irrespective of need for medical attention or time-loss and 10.3/1000 player-hours for injuries requiring at least 7 days absence from games; equivalent to a 28.4% and 12.1% risk of being injured over a season. Study heterogeneity contributed to a wide variation in injury incidence. Public injury surveillance and prevention systems have been successful in reducing injury rates in other countries.

A total of 65 studies were included, including 24 predominantly investigating mild (mTBI), seven moderate (modTBI) and 33 severe (sTBI); severity was not reported in one study.Results: In mTBI studies, the association between APOE$epsilon$4 and post-TBI outcome was concluded as non-contributory in 14 studies (58.3%), hazardous in nine (37.5%) and protective in one (4.2%). In sTBI studies, the role of APOE$epsilon$4 was hazardous in 21 (63.6%), non-contributory in nine (27.3%) and protective in three (9.1%). Of the seven studies investigating dementia outcomes, four observed a hazardous association with APOE$epsilon$4, while three reported no association. Six studies examined Alzheimers dementia pathology, of which three reported a hazardous influence of APOE$epsilon$4.Conclusions: The influence of APOE$epsilon$4 on neuropsychological testing, functional outcome and in paediatric populations was incongruous.

abstract = {BACKGROUND: While there is concern regarding head, face, and eye injuries in field hockey, prompting some to recommend the use of protective equipment such as goggles and helmets, little has been written about their incidence and mechanism of injury in the modern game of field hockey. The elucidation of this information will better inform the development of maximally effective injury prevention schemes to protect the athlete while maintaining the integrity of the game. PURPOSE: To determine the incidence and epidemiology of head, face, and eye injuries in United States collegiate women's field hockey players from 2004-2005 to 2008-2009. STUDY DESIGN: Descriptive epidemiological study. METHODS: All head, face, and eye injuries reported to the National Collegiate Athletic Association Injury Surveillance System for collegiate women's field hockey athletes from the 2004-2005 through 2008-2009 seasons were analyzed. Data regarding the event type, injury mechanism, body part injured, type of injury, outcome, and time lost were reviewed. The weighted injury incidence per 1000 athlete-exposures (AEs) was calculated using the exposure data set for the same years; 95% CIs were calculated based on a normal approximation to the Poisson distribution. RESULTS: There were 150 reported traumatic injuries during this time period, with a weighted occurrence of 1587.3 injuries. The overall incidence of head, face, and eye injuries in collegiate women's field hockey was 0.94 per 1000 AEs (95% CI, 0.86-1.19). Injuries to the head or face, other than the mouth, nose, and eye, accounted for 75.3% of these injuries. The incidence of eye injuries was 0.07 per 1000 AEs (95% CI, 0.03-0.12); nose injuries occurred at a rate of 0.10 per 1000 AEs (95% CI, 0.05-0.15). The rate of traumatic dental injuries was 0.06 per 1000 AEs (95% CI, 0.04-0.14). Contact with an apparatus caused 72.9% of all injuries; specifically, contact with an elevated ball accounted for 47.9% of all injuries, and contact with an elevated stick caused 21.7% of all injuries. While the majority of players suffering a head, face, or eye injury were able to return to sport that season (90.0%), the remaining athletes suffered season-ending injuries (10%). Concussions accounted for 42.8% of all head, face, and eye injuries reported (0.40 per 1000 AEs; 95% CI, 0.32-0.53). CONCLUSION: Head, face, and eye injuries occur regularly in women's field hockey. This description of the injury profile and mechanisms of injury may be used to design appropriate injury prevention schemes for the sport.Copyright © 2015 The Author(s).},

abstract = {BACKGROUND: The National Collegiate Athletic Association (NCAA) has recently highlighted mental health concerns in student athletes, though the incidence of suicide among NCAA athletes is unclear. The purpose of this study was to determine the rate of suicide among NCAA athletes. HYPOTHESIS: The incidence of suicide in NCAA athletes differs by sex, race, sport, and division. STUDY DESIGN: Retrospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: NCAA Memorial Resolutions list and published NCAA demographic data were used to identify student-athlete deaths and total participant seasons from 2003-2004 through 2011-2012. Deaths were analyzed by age, sex, race, division, and sport. RESULTS: Over the 9-year study period, 35 cases of suicide were identified from a review of 477 student-athlete deaths during 3,773,309 individual participant seasons. The overall suicide rate was 0.93/100,000 per year. Suicide represented 7.3% (35/477) of all-cause mortality among NCAA student athletes. The annual incidence of suicide in male athletes was 1.35/100,000 and in female athletes was 0.37/100,000 (relative risk [RR], 3.7; P \< 0.01). The incidence in African American athletes was 1.22/100,000 and in white athletes was 0.87/100,000 (RR, 1.4; P = 0.45). The highest rate of suicide occurred in men's football (2.25/100,000), and football athletes had a relative risk of 2.2 (P = 0.03) of committing suicide compared with other male, nonfootball athletes. CONCLUSION: The suicide rate in NCAA athletes appears to be lower than that of the general and collegiate population of similar age. NCAA male athletes have a significantly higher rate of suicide compared with female athletes, and football athletes appear to be at greatest risk. CLINICAL RELEVANCE: Suicide represents a preventable cause of death, and development of effective prevention programs is recommended. Copyright © 2015 The Author(s).},

abstract = {Objectives To identify the circumstances in which international rugby players exit the playing area during match activities and to define a safe run-off distance around the playing area. Method An observational study using video recordings of 102 matches associated with the Rugby World Cup (2011), Rugby Championship (2013, 2014) and Six Nations Championship (2013, 2014) were used to analyse every event in which one or more players exited the playing area during normal match activities. The circumstances in which a player exited the playing area were categorised using a range of parameters: playing position, location, out-of-play region, match activity, distance travelled over the touchline, contacts made with pitchside fixtures and fittings. Results Ninety-five per cent of player-excursions took place within 5.2 m of the touchline. Players exiting the playing area were nearly three times more likely to be a back than a forward (p\<0.001) and the event was more likely to take place when a team was defending than attacking (p\<0.001). Being forced out of play during a contact event (70%) was the major reason for players exiting the playing area. Most players (88%) exiting the playing area only made contact with the perimeter area surface; a small proportion of players contacted touchline flags (6.1%), advertising boards (2.3%) and TV cameras/equipment (1.0%). Conclusions A minimum hazard-free distance of 5 m around a Rugby pitch is proposed based on the 95% percentile frequency distribution of player-excursion events into the areas contiguous with the playing area. © 2015 BMJ Publishing Group.

Loss of consciousness was observed in 30% of cases. Common observable signs of injury included clutching of the head, balance problems or wobbly legs and a blank or vacant state. There were no post-concussive seizures. All players with loss of consciousness were removed from play. However, only half of the total sample was removed from play and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned the following week. Illegal play accounted for 25% of all concussions.Conclusions: Video analysis may be a useful method to study the incidence, mechanism and management of concussion in sports such as Rugby League. Future studies may include larger numbers to validate this preliminary data and may also investigate other levels of play and age ranges. © 2015 Taylor and Francis Group, LLC.},

abstract = {Background: Since their conception during the mid-1970s, international participation in extreme sports has grown rapidly. The recent death of extreme snowmobiler Caleb Moore at the 2013 Winter X Games has demonstrated the serious risks associated with these sports. Purpose: To examine the incidence and prevalence of head and neck injuries (HNIs) in extreme sports. Study Design: Descriptive epidemiological study. Methods: The National Electronic Injury Surveillance System (NEISS) was used to acquire data from 7 sports (2000-2011) that were included in the Winter and Summer X Games. Data from the NEISS database were collected for each individual sport per year and type of HNI. Cumulative data for overall incidence and injuries over the entire 11-year period were calculated. National estimates were determined using NEISS-weighted calculations. Incidence rates were calculated for extreme sports using data from Outdoor Foundation Participation Reports. Results: Over 4 million injuries were reported between 2000 and 2011, of which 11.3% were HNIs. Of all HNIs, 83% were head injuries and 17% neck injuries. The 4 sports with the highest total incidence of HNI were skateboarding (129,600), snowboarding (97,527), skiing (83,313), and motocross (78,236). Severe HNI (cervical or skull fracture) accounted for 2.5% of extreme sports HNIs. Of these, skateboarding had the highest percentage of severe HNIs. Conclusion: The number of serious injuries suffered in extreme sports has increased as participation in the sports continues to grow. A greater awareness of the dangers associated with these sports offers an opportunity for sports medicine and orthopaedic physicians to advocate for safer equipment, improved on-site medical care, and further research regarding extreme sports injuries. © 2015 The Author(s).},

abstract = {Purpose of Review: Growing public health concern exists over the incidence of chronic traumatic brain injury (TBI) in athletes participating in contact sports. Chronic TBI represents a spectrum of disorders associated with long-term consequences of single or repetitive TBI and includes chronic traumatic encephalopathy (CTE), chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologists should be familiar with the different types of chronic TBI and their diagnostic criteria. Recent Findings: CTE is the most severe chronic TBI and represents the neurologic consequences of repetitive mild TBI. It is particularly noted among boxers and football players. CTE presents with behavioral, cognitive, and motor symptoms, and can only be definitively diagnosed postmortem. Chronic postconcussion syndrome is defined as postconcussion symptoms that last longer than 1 year and do not appear to resolve; it may develop after a single concussive event. Chronic neurocognitive impairment is an all-encompassing clinical term denoting long-term neurologic sequelae secondary to sports-related trauma and can present either within the postconcussion syndrome or years after a symptom-free interval. Summary: This article discusses the diagnostic evaluation of chronic TBI, including clinical history, neurologic examination, neuropsychological testing, neuroimaging, and laboratory testing, as well as the distinctions between CTE, chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologic impairment among athletes exposed to repetitive brain injury appears to be a real phenomenon. Because CTE has no established treatment, prevention is of paramount importance for athletes participating in contact sports. © 2014, American Academy of Neurology.},

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

abstract = {OBJECTIVE: Childhood bicycle-related head injuries can be prevented through the use of helmets. Although helmet legislation has proved to be a successful strategy for the adoption of helmets, its effect on the rates of head injury is uncertain. In Canada, 4 provinces have such legislation. The objective of this study was to measure the impact of helmet legislation on bicycle-related head injuries in Canadian children. METHODS: Routinely collected data from the Canadian Institute for Health Information identified all Canadian children (5-19 years) who were hospitalized for bicycling-related injuries from 1994-1998. Children were categorized as head or other injury on the basis of International Classification of Diseases, Ninth Revision, codes. Rates of head injuries and other injuries were compared over time in provinces that adopted legislation and those that did not. RESULTS: Of the 9650 children who were hospitalized because of a bicycle-related injury, 3426 sustained injuries to the head and face and the remaining 6224 had other injuries. The bicycle-related head injury rate declined significantly (45% reduction) in provinces where legislation had been adopted compared with provinces and territories that did not adopt legislation (27% reduction). CONCLUSION: This country-wide study compared rates of head injury in regions with and without mandatory helmet legislation. Comparing head injuries with other non-head-injured children controlled for potential differences in children's cycling habits. The strong protective association between helmet legislation and head injuries supports the adoption of helmet legislation as an effective tool in the prevention of childhood bicycle-related head injuries.},

abstract = {The National Rugby League (NRL) in Australia introduced a new 'concussion interchange rule' (CIR) in 2014, whereby a player suspected of having sustained a concussion can be removed from play, and assessed, without an interchange being tallied against the player's team. We conducted a video analysis, describing player and injury characteristics, situational factors, concussion signs, and return to play for each "CIR" event for the 2014 season. There were 167 reported uses of the CIR. Apparent loss of consciousness/unresponsiveness was observed in 32% of cases, loss of muscle tone in 54%, clutching the head in 70%, unsteadiness of gait in 66%, and a vacant stare in 66%. More than half of the players who were removed under the CIR returned to play later in the same match (57%). Most incidences occurred from a hit up (62%) and occurred during a tackle where the initial contact was with the upper body (80%). The new concussion interchange rule has been used frequently during the first season of its implementation. In many cases, there appeared to be video evidence of injury but the athlete was cleared to return to play. More research is needed on the usefulness of video review for identifying signs of concussive injury. Copyright © Georg Thieme Verlag KG Stuttgart . New York.},

However, few authors to date have updated injury rates (IRs) and time loss between male and female concussed athletes. OBJECTIVE: To examine sex differences in IRs and time loss in concussed National Collegiate Athletic Association (NCAA) athletes. DESIGN: Descriptive epidemiologic study. SETTING: National Collegiate Athletic Association athletics. PATIENTS OR OTHER PARTICIPANTS: A total of 1702 concusssed NCAA athletes, consisting of 903 females and 779 males participating in soccer, basketball, ice hockey, lacrosse, softball, or baseball over a 5-year period from 2004-2005 through 2008-2009. MAIN OUTCOME MEASURE(S): Using the NCAA Injury Surveillance Program, athletic trainers reported concussions, athlete-exposures (AEs), and time loss across 10 NCAA sports. An IR is the number of injuries in a particular category divided by the number of AEs in that category. RESULTS: During the study period, 1702 concussions were reported during 4 170 427 AEs for an overall total of 5.47 per 10 000 AEs. In sex-comparable sports, females had a 1.4 times higher overall concussion IR than males (IRs = 4.84 and 3.46, respectively), with greater rates in women's baseball/softball, basketball, ice hockey, and soccer than men. Female soccer and basketball players also displayed more time loss after concussion compared with male basketball and soccer players. CONCLUSIONS: Female athletes sustained a higher rate of concussion and, in all sports except lacrosse, had greater time loss from concussion than male athletes. Additional research is needed on sex differences in time loss after concussions.},

abstract = {A systematic review of rugby union and league injuries among players under the age of 21 years was carried out to calculate probabilities of match injury for a player over a season and a pooled estimate of match injury incidence where studies were sufficiently similar. The probability of a player being injured over a season ranged from 6% to 90% for rugby union and 68% to 96% for rugby league. The pooled injury incidence estimate for rugby union was 26.7/1000 player-hours for injuries irrespective of need for medical attention or time-loss and 10.3/1000 player-hours for injuries requiring at least 7 days absence from games; equivalent to a 28.4% and 12.1% risk of being injured over a season. Study heterogeneity contributed to a wide variation in injury incidence. Public injury surveillance and prevention systems have been successful in reducing injury rates in other countries.

abstract = {Background: The apolipoprotein E gene (APOE) has emerged as a candidate for prognosticating traumatic brain injury (TBI) recovery, with APOE$epsilon$4 identified as a susceptibility marker for poor outcome, despite large discrepancy in its reported influence post-TBI.Methods: A systematic review was conducted, including all primary articles investigating the role of APOE$epsilon$4 on TBI outcome. A total of 65 studies were included, including 24 predominantly investigating mild (mTBI), seven moderate (modTBI) and 33 severe (sTBI); severity was not reported in one study.Results: In mTBI studies, the association between APOE$epsilon$4 and post-TBI outcome was concluded as non-contributory in 14 studies (58.3%), hazardous in nine (37.5%) and protective in one (4.2%). In sTBI studies, the role of APOE$epsilon$4 was hazardous in 21 (63.6%), non-contributory in nine (27.3%) and protective in three (9.1%). Of the seven studies investigating dementia outcomes, four observed a hazardous association with APOE$epsilon$4, while three reported no association. Six studies examined Alzheimers dementia pathology, of which three reported a hazardous influence of APOE$epsilon$4.Conclusions: The influence of APOE$epsilon$4 on neuropsychological testing, functional outcome and in paediatric populations was incongruous. This review supports the majority of research indicating APOE$epsilon$4 adversely influences recovery following TBI, particularly with respect to dementia-related outcomes and outcomes following sTBI. © 2015 Taylor \& Francis Group, LLC.},

abstract = {BACKGROUND: While there is concern regarding head, face, and eye injuries in field hockey, prompting some to recommend the use of protective equipment such as goggles and helmets, little has been written about their incidence and mechanism of injury in the modern game of field hockey. The elucidation of this information will better inform the development of maximally effective injury prevention schemes to protect the athlete while maintaining the integrity of the game. PURPOSE: To determine the incidence and epidemiology of head, face, and eye injuries in United States collegiate women's field hockey players from 2004-2005 to 2008-2009. STUDY DESIGN: Descriptive epidemiological study. METHODS: All head, face, and eye injuries reported to the National Collegiate Athletic Association Injury Surveillance System for collegiate women's field hockey athletes from the 2004-2005 through 2008-2009 seasons were analyzed. Data regarding the event type, injury mechanism, body part injured, type of injury, outcome, and time lost were reviewed. The weighted injury incidence per 1000 athlete-exposures (AEs) was calculated using the exposure data set for the same years; 95% CIs were calculated based on a normal approximation to the Poisson distribution. RESULTS: There were 150 reported traumatic injuries during this time period, with a weighted occurrence of 1587.3 injuries. The overall incidence of head, face, and eye injuries in collegiate women's field hockey was 0.94 per 1000 AEs (95% CI, 0.86-1.19). Injuries to the head or face, other than the mouth, nose, and eye, accounted for 75.3% of these injuries. The incidence of eye injuries was 0.07 per 1000 AEs (95% CI, 0.03-0.12); nose injuries occurred at a rate of 0.10 per 1000 AEs (95% CI, 0.05-0.15). The rate of traumatic dental injuries was 0.06 per 1000 AEs (95% CI, 0.04-0.14). Contact with an apparatus caused 72.9% of all injuries; specifically, contact with an elevated ball accounted for 47.9% of all injuries, and contact with an elevated stick caused 21.7% of all injuries. While the majority of players suffering a head, face, or eye injury were able to return to sport that season (90.0%), the remaining athletes suffered season-ending injuries (10%). Concussions accounted for 42.8% of all head, face, and eye injuries reported (0.40 per 1000 AEs; 95% CI, 0.32-0.53). CONCLUSION: Head, face, and eye injuries occur regularly in women's field hockey. This description of the injury profile and mechanisms of injury may be used to design appropriate injury prevention schemes for the sport.Copyright © 2015 The Author(s).},

abstract = {BACKGROUND: The National Collegiate Athletic Association (NCAA) has recently highlighted mental health concerns in student athletes, though the incidence of suicide among NCAA athletes is unclear. The purpose of this study was to determine the rate of suicide among NCAA athletes. HYPOTHESIS: The incidence of suicide in NCAA athletes differs by sex, race, sport, and division. STUDY DESIGN: Retrospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: NCAA Memorial Resolutions list and published NCAA demographic data were used to identify student-athlete deaths and total participant seasons from 2003-2004 through 2011-2012. Deaths were analyzed by age, sex, race, division, and sport. RESULTS: Over the 9-year study period, 35 cases of suicide were identified from a review of 477 student-athlete deaths during 3,773,309 individual participant seasons. The overall suicide rate was 0.93/100,000 per year. Suicide represented 7.3% (35/477) of all-cause mortality among NCAA student athletes. The annual incidence of suicide in male athletes was 1.35/100,000 and in female athletes was 0.37/100,000 (relative risk [RR], 3.7; P \< 0.01). The incidence in African American athletes was 1.22/100,000 and in white athletes was 0.87/100,000 (RR, 1.4; P = 0.45). The highest rate of suicide occurred in men's football (2.25/100,000), and football athletes had a relative risk of 2.2 (P = 0.03) of committing suicide compared with other male, nonfootball athletes. CONCLUSION: The suicide rate in NCAA athletes appears to be lower than that of the general and collegiate population of similar age. NCAA male athletes have a significantly higher rate of suicide compared with female athletes, and football athletes appear to be at greatest risk. CLINICAL RELEVANCE: Suicide represents a preventable cause of death, and development of effective prevention programs is recommended. Copyright © 2015 The Author(s).},

abstract = {Objectives To identify the circumstances in which international rugby players exit the playing area during match activities and to define a safe run-off distance around the playing area. Method An observational study using video recordings of 102 matches associated with the Rugby World Cup (2011), Rugby Championship (2013, 2014) and Six Nations Championship (2013, 2014) were used to analyse every event in which one or more players exited the playing area during normal match activities. The circumstances in which a player exited the playing area were categorised using a range of parameters: playing position, location, out-of-play region, match activity, distance travelled over the touchline, contacts made with pitchside fixtures and fittings. Results Ninety-five per cent of player-excursions took place within 5.2 m of the touchline. Players exiting the playing area were nearly three times more likely to be a back than a forward (p\<0.001) and the event was more likely to take place when a team was defending than attacking (p\<0.001). Being forced out of play during a contact event (70%) was the major reason for players exiting the playing area. Most players (88%) exiting the playing area only made contact with the perimeter area surface; a small proportion of players contacted touchline flags (6.1%), advertising boards (2.3%) and TV cameras/equipment (1.0%). Conclusions A minimum hazard-free distance of 5 m around a Rugby pitch is proposed based on the 95% percentile frequency distribution of player-excursion events into the areas contiguous with the playing area. © 2015 BMJ Publishing Group.

Loss of consciousness was observed in 30% of cases. Common observable signs of injury included clutching of the head, balance problems or wobbly legs and a blank or vacant state. There were no post-concussive seizures. All players with loss of consciousness were removed from play. However, only half of the total sample was removed from play and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned the following week. Illegal play accounted for 25% of all concussions.Conclusions: Video analysis may be a useful method to study the incidence, mechanism and management of concussion in sports such as Rugby League. Future studies may include larger numbers to validate this preliminary data and may also investigate other levels of play and age ranges. © 2015 Taylor and Francis Group, LLC.},

abstract = {Background: Since their conception during the mid-1970s, international participation in extreme sports has grown rapidly. The recent death of extreme snowmobiler Caleb Moore at the 2013 Winter X Games has demonstrated the serious risks associated with these sports. Purpose: To examine the incidence and prevalence of head and neck injuries (HNIs) in extreme sports. Study Design: Descriptive epidemiological study. Methods: The National Electronic Injury Surveillance System (NEISS) was used to acquire data from 7 sports (2000-2011) that were included in the Winter and Summer X Games. Data from the NEISS database were collected for each individual sport per year and type of HNI. Cumulative data for overall incidence and injuries over the entire 11-year period were calculated. National estimates were determined using NEISS-weighted calculations. Incidence rates were calculated for extreme sports using data from Outdoor Foundation Participation Reports. Results: Over 4 million injuries were reported between 2000 and 2011, of which 11.3% were HNIs. Of all HNIs, 83% were head injuries and 17% neck injuries. The 4 sports with the highest total incidence of HNI were skateboarding (129,600), snowboarding (97,527), skiing (83,313), and motocross (78,236). Severe HNI (cervical or skull fracture) accounted for 2.5% of extreme sports HNIs. Of these, skateboarding had the highest percentage of severe HNIs. Conclusion: The number of serious injuries suffered in extreme sports has increased as participation in the sports continues to grow. A greater awareness of the dangers associated with these sports offers an opportunity for sports medicine and orthopaedic physicians to advocate for safer equipment, improved on-site medical care, and further research regarding extreme sports injuries. © 2015 The Author(s).},

abstract = {Purpose of Review: Growing public health concern exists over the incidence of chronic traumatic brain injury (TBI) in athletes participating in contact sports. Chronic TBI represents a spectrum of disorders associated with long-term consequences of single or repetitive TBI and includes chronic traumatic encephalopathy (CTE), chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologists should be familiar with the different types of chronic TBI and their diagnostic criteria. Recent Findings: CTE is the most severe chronic TBI and represents the neurologic consequences of repetitive mild TBI. It is particularly noted among boxers and football players. CTE presents with behavioral, cognitive, and motor symptoms, and can only be definitively diagnosed postmortem. Chronic postconcussion syndrome is defined as postconcussion symptoms that last longer than 1 year and do not appear to resolve; it may develop after a single concussive event. Chronic neurocognitive impairment is an all-encompassing clinical term denoting long-term neurologic sequelae secondary to sports-related trauma and can present either within the postconcussion syndrome or years after a symptom-free interval. Summary: This article discusses the diagnostic evaluation of chronic TBI, including clinical history, neurologic examination, neuropsychological testing, neuroimaging, and laboratory testing, as well as the distinctions between CTE, chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologic impairment among athletes exposed to repetitive brain injury appears to be a real phenomenon. Because CTE has no established treatment, prevention is of paramount importance for athletes participating in contact sports. © 2014, American Academy of Neurology.},

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

abstract = {OBJECTIVE: Childhood bicycle-related head injuries can be prevented through the use of helmets. Although helmet legislation has proved to be a successful strategy for the adoption of helmets, its effect on the rates of head injury is uncertain. In Canada, 4 provinces have such legislation. The objective of this study was to measure the impact of helmet legislation on bicycle-related head injuries in Canadian children. METHODS: Routinely collected data from the Canadian Institute for Health Information identified all Canadian children (5-19 years) who were hospitalized for bicycling-related injuries from 1994-1998. Children were categorized as head or other injury on the basis of International Classification of Diseases, Ninth Revision, codes. Rates of head injuries and other injuries were compared over time in provinces that adopted legislation and those that did not. RESULTS: Of the 9650 children who were hospitalized because of a bicycle-related injury, 3426 sustained injuries to the head and face and the remaining 6224 had other injuries. The bicycle-related head injury rate declined significantly (45% reduction) in provinces where legislation had been adopted compared with provinces and territories that did not adopt legislation (27% reduction). CONCLUSION: This country-wide study compared rates of head injury in regions with and without mandatory helmet legislation. Comparing head injuries with other non-head-injured children controlled for potential differences in children's cycling habits. The strong protective association between helmet legislation and head injuries supports the adoption of helmet legislation as an effective tool in the prevention of childhood bicycle-related head injuries.},
