Sudden Cardiac Death in National Collegiate Athletic Association Athletes: A 20-Year Study.

BACKGROUND: Understanding the incidence, causes, and trends of sudden cardiac death (SCD) among young competitive athletes is critical to inform preventive policies. METHODS: This study included National Collegiate Athletic Association athlete deaths during a 20-year time frame (July 1, 2002, through June 30, 2022). Athlete deaths were identified through 4 separate independent databases and search strategies (National Collegiate Athletic Association resolutions list, Parent Heart Watch database and media reports, National Center for Catastrophic Sports Injury Research database, and insurance claims). Autopsy reports and medical history were reviewed by an expert panel to adjudicate causes of SCD. RESULTS: A total of 143 SCD cases in National Collegiate Athletic Association athletes were identified from 1102 total deaths. The National Collegiate Athletic Association resolutions list identified 117 of 143 (82%), the Parent Heart Watch database or media reports identified 89 of 143 (62%), the National Center for Catastrophic Sports Injury Research database identified 63 of 143 (44%), and insurance claims identified 27 of 143 (19%) SCD cases. The overall incidence of SCD was 1:63 682 athlete-years (95% CI, 1:54 065-1:75 010). Incidence was higher in male athletes than in female athletes (1:43 348 [95% CI, 1:36 228-1:51 867] versus 1:164 504 [95% CI, 1:110 552-1:244 787] athlete-years, respectively) and Black athletes compared with White athletes (1:26 704 [1:20 417-1:34 925] versus 1:74 581 [1:60 247-1:92 326] athlete-years, respectively). The highest incidence of SCD was among Division I male basketball players (1:8188 [White, 1:5848; Black, 1:7696 athlete-years]). The incidence rate for SCD decreased over the study period (5-year incidence rate ratio, 0.71 [95% CI, 0.61-0.82]), whereas the rate of noncardiovascular deaths remained stable (5-year incidence rate ratio, 0.98 [95% CI, 0.94-1.04]). Autopsy-negative sudden unexplained death (19.5%) was the most common postmortem examination finding, followed by idiopathic left ventricular hypertrophy or possible cardiomyopathy (16.9%) and hypertrophic cardiomyopathy (12.7%), in cases with enough information for adjudication (118 of 143). Eight cases of death were attributable to myocarditis over the study period (1 case from January 1, 2020, through June 30, 2022), with none attributed to COVID-19 infection. SCD events were exertional in 50% of cases. Exertional SCD was more common among those with coronary artery anomalies (100%) and arrhythmogenic cardiomyopathy (83%). CONCLUSIONS: The incidence of SCD in college athletes has decreased. Male sex, Black race, and basketball are associated with a higher incidence of SCD.

2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for the Management of Hypertrophic Cardiomyopathy: A Report of the American Heart Association/American College of Cardiology Joint Committee on Clinical Practice Guidelines.

AIM: The "2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for the Management of Hypertrophic Cardiomyopathy" provides recommendations to guide clinicians in the management of patients with hypertrophic cardiomyopathy. METHODS: A comprehensive literature search was conducted from September 14, 2022, to November 22, 2022, encompassing studies, reviews, and other evidence on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, the Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. Additional relevant studies, published through May 23, 2023, during the guideline writing process, were also considered by the writing committee and added to the evidence tables, where appropriate. STRUCTURE: Hypertrophic cardiomyopathy remains a common genetic heart disease reported in populations globally. Recommendations from the "2020 AHA/ACC Guideline for the Diagnosis and Treatment of Patients With Hypertrophic Cardiomyopathy" have been updated with new evidence to guide clinicians.

Focus areas and methodological characteristics of North American-based health disparity research in sports medicine: a scoping review.

OBJECTIVE: Health disparities are widely prevalent; however, little has been done to examine and address their causes and effects in sports and exercise medicine (SEM). We aimed to summarise the focus areas and methodology used for existing North American health disparity research in SEM and to identify gaps in the evidence base. DESIGN: Scoping review. DATA SOURCES: Systematic literature search of PubMed, Scopus, SPORTDiscus, CINAHL Plus with Full Text, Web of Science Core Collection and Cochrane Central Register of Controlled Trials. ELIGIBILITY CRITERIA: Full-text, peer-reviewed manuscripts of primary research, conducted in North America; published in the year 2000 or after, in English; and focusing on organised sports were included. RESULTS: 103 articles met inclusion criteria. Articles were classified into five focus areas: access to and participation in sports (n=45), access to SEM care (n=28), health-related outcomes in SEM (n=24), provider representation in SEM (n=5) and methodology (n=1). Race/ethnicity (n=39), socioeconomic status (n=28) and sex (n=27) were the most studied potential causes of health disparities, whereas sexual orientation (n=5), location (rural/urban/suburban, n=5), education level (n=5), body composition (n=5), gender identity (n=4) and language (n=2) were the least studied. Most articles (n=74) were cross-sectional, conducted on youth (n=55) and originated in the USA (n=90). CONCLUSION: Health disparity research relevant to SEM in North America is limited. The overall volume and breadth of research required to identify patterns in a heterogeneous sports landscape, which can then be used to inform positive change, need expansion. Intentional research focused on assessing the intersectionality, causes and consequences of health disparities in SEM is necessary.

Using artificial intelligence for exercise prescription in personalised health promotion: A critical evaluation of OpenAI's GPT-4 model.

The rise of artificial intelligence (AI) applications in healthcare provides new possibilities for personalized health management. AI-based fitness applications are becoming more common, facilitating the opportunity for individualised exercise prescription. However, the use of AI carries the risk of inadequate expert supervision, and the efficacy and validity of such applications have not been thoroughly investigated, particularly in the context of diverse health conditions. The aim of the study was to critically assess the efficacy of exercise prescriptions generated by OpenAI's Generative Pre-Trained Transformer 4 (GPT-4) model for five example patient profiles with diverse health conditions and fitness goals. Our focus was to assess the model's ability to generate exercise prescriptions based on a singular, initial interaction, akin to a typical user experience. The evaluation was conducted by leading experts in the field of exercise prescription. Five distinct scenarios were formulated, each representing a hypothetical individual with a specific health condition and fitness objective. Upon receiving details of each individual, the GPT-4 model was tasked with generating a 30-day exercise program. These AI-derived exercise programs were subsequently subjected to a thorough evaluation by experts in exercise prescription. The evaluation encompassed adherence to established principles of frequency, intensity, time, and exercise type; integration of perceived exertion levels; consideration for medication intake and the respective medical condition; and the extent of program individualization tailored to each hypothetical profile. The AI model could create general safety-conscious exercise programs for various scenarios. However, the AI-generated exercise prescriptions lacked precision in addressing individual health conditions and goals, often prioritizing excessive safety over the effectiveness of training. The AI-based approach aimed to ensure patient improvement through gradual increases in training load and intensity, but the model's potential to fine-tune its recommendations through ongoing interaction was not fully satisfying. AI technologies, in their current state, can serve as supplemental tools in exercise prescription, particularly in enhancing accessibility for individuals unable to access, often costly, professional advice. However, AI technologies are not yet recommended as a substitute for personalized, progressive, and health condition-specific prescriptions provided by healthcare and fitness professionals. Further research is needed to explore more interactive use of AI models and integration of real-time physiological feedback.

Gender bias in sports medicine: an international assessment of sports medicine physicians' perceptions of their interactions with athletes, coaches, athletic trainers and other physicians.

OBJECTIVES: To evaluate the difference between female and male sports medicine physicians regarding disrespectful attitudes and sexual harassment perceived from athletes, coaches, physicians, athletic trainers (ATs) and organisations/administrations. METHODS AND STUDY DESIGN: anonymous survey was distributed to sports medicine physicians practicing in 51 countries. χ2 analysis was used to detect differences between female and male sports medicine physicians and logistic regression analysis was used to determine the independent variables that affect disrespectful attitudes and sexual harassment from sports participants. RESULTS: 1193 sports medicine physicians (31.9% female) participated from 51 countries. The survey revealed that female physicians, compared with male physicians, perceive significantly more disrespect or have their judgement questioned more by the following categories: male and female athletes, male and female coaches, female physicians with more years of experience, male physicians (regardless of years of experience), male and female ATs and organisation/administrations (all p<0.05). The only category where the frequency of disrespect was perceived equally by male and female physicians was during their interactions with female physicians who have the same or lesser years of experience. Female sports medicine physicians noted more sexual harassment than male physicians during interactions with male athletes, coaches, ATs and physicians (all p<0.001). In the logistic regression, gender was a related factor for perceiving disrespect, especially from male coaches (OR=2.01) and physicians with more years of experience (OR=2.18). CONCLUSIONS: Female sports medicine physicians around the world experience disrespectful attitudes, questioning of their judgement and are sexually harassed significantly more often than male counterparts.

Return to play with hypertrophic cardiomyopathy: are we moving too fast? A critical review.

The diagnosis of a potentially lethal cardiovascular disease in a young athlete presents a complex dilemma regarding athlete safety, patient autonomy, team or institutional risk tolerance and medical decision-making. Consensus cardiology recommendations previously supported the 'blanket' disqualification of athletes with hypertrophic cardiomyopathy (HCM) from competitive sport. More recently, epidemiological studies examining the relative contribution of HCM as a cause of sudden cardiac death (SCD) in young athletes and reports from small cohorts of older athletes with HCM that continue to exercise have fueled debate whether it is safe to play with HCM. Shared decision-making is endorsed within the sports cardiology community in which athletes can make an informed decision about treatment options and potentially elect to continue competitive sports participation. This review critically examines the available evidence relevant to sports eligibility decisions in young athletes diagnosed with HCM. Histopathologically, HCM presents an unstable myocardial substrate that is vulnerable to ventricular tachyarrhythmias during exercise. Studies support that young age and intense competitive sports are risk factors for SCD in patients with HCM. We provide an estimate of annual mortality based on our understanding of disease prevalence and the incidence of HCM-related SCD in different athlete populations. Adolescent and young adult male athletes and athletes participating in a higher risk sport such as basketball, soccer and American football exhibit a greater risk. This review explores the potential harms and benefits of sports disqualification in athletes with HCM and details the challenges and limitations of shared decision-making when all parties may not agree.

Cardiovascular Screening of Elite Athletes by Sporting Organizations in Australia: A Survey of Chief Medical Officers.

OBJECTIVE: To compare cardiovascular screening policies of Australian elite sporting organizations. DESIGN: Online survey. SETTING: Elite/professional sports in Australia. PARTICIPANTS: Chief medical officers (CMOs) of elite/professional sports in Australia, including rugby union and league, cricket, tennis, Australian football, and cycling. ASSESSMENT OF VARIABLES: Survey questions about each sport's cardiac screening policy: which screening components were included [eg, history and physical (H&P), resting 12-lead electrocardiogram (ECG)], whether screening was mandatory, whether the policy applied to elite junior and/or adult players, and which criteria were used to interpret ECGs. MAIN OUTCOME MEASURES: Which sports had a formal cardiac screening policy, which athletes the policy applied to, components of screening, ECG interpretation criteria used. RESULTS: Chief medical officers for 22/31 (71%) sports responded, representing >5000 athletes. Of these, 19/22 (86%) perform regular screening (100% H&P; 89% included ECG) with international cyclists also having routine echocardiograms and stress testing. Thirty-three percent of CMOs used the 2017 International Criteria for athlete ECG interpretation. Screening was mandatory with enforcement (26%), mandatory without enforcement (48%), and opt-out (26%). All screened adult elite athletes, and 68% screened junior elite athletes. Forty-two percent indicated athletes were required to pay for screening tests, and 63% required athletes to pay for follow-up tests. Almost all (94%) sports with a sports physician as the CMO screened athletes. CONCLUSIONS: Most sports have a screening policy, with reasonable uniformity of components. All included H&P, and almost all included ECG. Only one sport included an echocardiogram and stress test as a standard (international players only). Promoting the latest ECG interpretation criteria may reduce false-positives and cost. Future work should explore cardiac emergency plans, screening infrastructure, cost, and long-term follow-up.

Preparticipation Cardiovascular Screening: An Infrastructure Assessment in Collegiate Athletics.

OBJECTIVE: To assess the available infrastructure for secondary testing after preparticipation cardiovascular screening of collegiate athletes. DESIGN: Cross-sectional study. SETTING: National Collegiate Athletic Association (NCAA) athletic programs PARTICIPANTS:: Team physicians. INTERVENTIONS: Online survey distributed by the NCAA and American Medical Society for Sports Medicine. MAIN OUTCOME MEASURES: Availability of secondary cardiovascular diagnostic testing and services. RESULTS: Team physicians from 235 schools completed the assessment, representing 21% of all NCAA schools. Ninety (38.3%) NCAA team physicians reported screening athletes using electrocardiogram (ECG). Division I schools were more likely than Division II and III schools to perform both screening ECG (RR, 2.38, P < 0.0001) and echocardiogram (RR, 2.83, P = 0.01). More than 97% of schools had access to resting echocardiogram, stress ECG/echocardiogram, and Holter monitoring within 25 miles with no significant variability between divisions, regions, or size of undergraduate student body. Cardiac magnetic resonance imaging and electrophysiology studies were available within 25 miles of more than 80% of schools, and genetics testing was available within 25 miles for 64.8%. CONCLUSIONS: Secondary testing for cardiovascular abnormalities seems to be readily available for NCAA athletes, regardless of division, region, or school size.

Association Between a Physical Activity Vital Sign and Cardiometabolic Disease in High-Risk Patients.

OBJECTIVE: To determine the association between the physical activity vital sign (PAVS) and markers of cardiometabolic disease. DESIGN: Patients were assessed through the PAVS, a validated tool self-reporting the frequency and duration of physical activity. Patients were categorized into 3 groups: inactive (0 minutes per week), underactive (1-149 minutes per week), and active (>150 minutes per week). Associations were tested between the PAVS and the cardiometabolic disease biomarkers of body mass index, hemoglobin A1c (A1c), blood pressure, and low-density lipoprotein (LDL) using one-way analyses of variance. SETTING: High-risk family medicine residency clinic. PARTICIPANTS: Two thousand three hundred twenty-one adult patients (age ≥ 18 years). RESULTS: Participants reported a mean of 97.87 (SD = 149.35) minutes per week of exercise. Overall, 50.1% reported physical inactivity, 25.7% were underactive, and 24.3% were active. Younger individuals (P < 0.001) and men (P < 0.05) reported more physical activity than older individuals and women. Patients who reported being active were significantly less likely to be overweight (P < 0.05), obese (P < 0.05), or hypertensive (P < 0.05), but there was no association with A1c or LDL levels. CONCLUSIONS: This is the first investigation to examine the PAVS in a high-risk population. In these patients, reported levels of physical inactivity are 150% higher than other clinical settings, and the PAVS is only associated with improvements in 2 of 4 major cardiometabolic risk factors. For this group, self-reported levels of physical activity may need to be higher for cardiovascular benefits to be realized in all 4 cardiometabolic domains. The PAVS offers health professionals an opportunity to encourage lifestyle-based interventions to reduce cardiovascular risk, but refinements may be necessary to address this population.

Identifiable Factors Associated With Acceptance Into Sports Medicine Fellowship Programs: A Brief Report.

OBJECTIVE: To identify factors associated with entry into primary care sports medicine (PCSM) fellowship programs. DESIGN: Primary care sports medicine fellowship directors (FDs) and fellowship faculty were surveyed regarding preferences for accepting applicants into their programs. SETTING: Survey study. PARTICIPANTS: Primary care sports medicine FDs and fellowship faculty. ASSESSMENT OF RISK FACTORS: Questions were designed to delineate factors [clinical experience, letters of recommendation (LOR), scholarship, service commitment, interview performance, etc] perceived to be associated with entry into PCSM fellowship (1-10 scale; 10 = highest value). Weighted mean ± SD were calculated for each question. MAIN OUTCOME MEASURES: Determination of most valued factors for entry into PCSM fellowship. RESULTS: Responses were provided by 242/2332 (10.4%) of the American Medical Society for Sports Medicine members, including 77 of 175 (44%) FDs. The top 3 factors for entry into PCSM fellowships for all respondents were as follows: interview performance (9.17 ± 1.13), LOR from SM fellowship faculty (8.20 ± 1.67), and high school game/event coverage (7.83 ± 1.70). Musculoskeletal ultrasound experience (4.50 ± 2.23) and residency training in pediatrics (4.58 ± 2.54), internal medicine (4.48 ± 2.44), emergency medicine (4.44 ± 2.59), and physical medicine and rehabilitation (4.40 ± 2.83) received the lowest scores. CONCLUSIONS: Applicants seeking entry into SM fellowships should prioritize performance during interviews, LOR from SM fellowship faculty, and team game/event coverage experiences.

Ion-acoustic dipolar vortex in degenerate magnetoplasma with ions/electrons thermal corrections.

Nonlinear evolution and propagation characteristics of an ion-acoustic (IA) dipolar vortex are examined in a magnetoplasma that comprises partially degenerate electrons and dynamic ions. The adiabatic ions reduce the quantum magnetohydrodynamic equations to a modified momentum equation. The latter admits a new solution and leads to an evolution equation for the description of a coherent IA dipolar vortex. Numerical analysis reveals that variations in the relevant plasma parameters alter the evolution condition for a stable vortex. The electron exchange-correlation enhances excitation of the vortex as it extends the parametric regime associated with the stable vortex solution. On the contrary, the ion temperature lessens the nonlinear evolution of the vortex. Importantly, a degree of enhancement in the exchange-correlation potential leads to the wave dispersion and-in return-widens the vortex potential spatially. The novel nature of the derived results stresses upon the comprehension of the ordered structures in the compact stars, the magnetic mirrors, the ionosphere, the pinch devices, etc., where thermal corrections significantly impact the waves dynamics.

Clinician Well-being during a Pandemic: Practices to Boost Resilience and Life Satisfaction.

The role of the sports medicine physician has been challenged in several ways during the COVID-19 pandemic, potentially eroding a sense of well-being. Four universal human needs related to flourishing and a sense of life satisfaction are the framework we use to examine the effects of a pandemic on sports medicine clinicians. We offer two evidence-based practices to promote well-being and resilience within each of the four universal needs.

Three dimensional ion-acoustic rogons in quantized anisotropic magnetoplasmas with trapped/untrapped electrons.

Three-dimensional (3D) modulational instability (MI) and ion-acoustic (IA) envelopes are studied in a quantized degenerate magnetoplasma, whose constituents are the trapped/untrapped electrons and anisotropic positive ions. By using quantum hydrodynamic equations and the multiscale reductive perturbation technique, a 3D nonlinear Schrödinger equation is derived to account for electron quantization and ion pressure anisotrophy effects. The potential excitations are shown stable (unstable) against the perturbations for Kc<0(Kc>0), where Kc is a critical parameter that accounts for the longitudinal (transverse) dispersion(s) and nonlinearity effects. Numerically, the nonlinear evolution of IA wavepackets into a 3D MI may be revealed in the ranges of low and high frequencies 0<ω≤0.05 and 0.75≤ω≤1.1. The quantizing magnetic field reduces (enhances) the group speed (wave frequency) of IA excitations, concentrating the wave energy to favor the modulational instability. Finite electronic temperature (viz.,Te≤10keV) enhances the untrapped electrons and significantly widens the instability domain Kc>0. The ionic pressure anisotropy increases the wave frequency (ω), piles up the harmonics under Kc>0, and give rise to modulational instability. The quantized magnetic field and anisotropic pressure reduce the amplitude and spatial extension of the IA rogons. This study is important for understanding the 3D MI and unstable excitations in degenerate plasmas, relevant to white dwarfs, neutron stars, and high-energy density experiments, where strong magnetic field quantizes the dynamics of trapped/untrapped electrons.

International recommendations for electrocardiographic interpretation in athletes.

Sudden cardiac death (SCD) is the leading cause of mortality in athletes during sport. A variety of mostly hereditary, structural, or electrical cardiac disorders are associated with SCD in young athletes, the majority of which can be identified or suggested by abnormalities on a resting 12-lead electrocardiogram (ECG). Whether used for diagnostic or screening purposes, physicians responsible for the cardiovascular care of athletes should be knowledgeable and competent in ECG interpretation in athletes. However, in most countries a shortage of physician expertise limits wider application of the ECG in the care of the athlete. A critical need exists for physician education in modern ECG interpretation that distinguishes normal physiological adaptations in athletes from distinctly abnormal findings suggestive of underlying pathology. Since the original 2010 European Society of Cardiology recommendations for ECG interpretation in athletes, ECG standards have evolved quickly over the last decade; pushed by a growing body of scientific data that both tests proposed criteria sets and establishes new evidence to guide refinements. On 26-27 February 2015, an international group of experts in sports cardiology, inherited cardiac disease, and sports medicine convened in Seattle, Washington, to update contemporary standards for ECG interpretation in athletes. The objective of the meeting was to define and revise ECG interpretation standards based on new and emerging research and to develop a clear guide to the proper evaluation of ECG abnormalities in athletes. This statement represents an international consensus for ECG interpretation in athletes and provides expert opinion-based recommendations linking specific ECG abnormalities and the secondary evaluation for conditions associated with SCD.

Experimental investigation and micromagnetic simulations of hybrid CoCr2O4/Ni coaxial nanostructures.

Multiphase CoCr2O4/Ni core-shell nanowires (NWs) have been synthesized within anodic aluminum oxide membranes by the combination of the sol-gel method with electrodeposition techniques. X-ray diffraction and x-ray photoemission spectroscopy results confirmed the formation of a cubic spinel structure of CoCr2O4 shell with space group Fd-3m (227). The morphology and composition of the as-grown NWs were studied by field emission scanning electron microscopy, as well as transmission electron microscopy. The magnetic properties of the CoCr2O4 NT shell and hybrid CoCr2O4/Ni NWs were measured at low temperature using a physical property measurement system. The temperature dependence of the magnetization curves showed that CoCr2O4 NTs undergo a transition from a paramagnetic state to a ferrimagnetic state at about 90 K and a spiral ordering transition temperature near 22 K. An enhanced coercivity and saturation field were observed for the CoCr2O4/Ni core-shell NWs compared to the single-phase Ni NWs. Micromagnetic simulation results indicated that there is a strong coupling between the shell and core layers during the magnetization reversal process. The combination of hard CoCr2O4 and soft Ni in a single NW structure may have potential applications in future multifunctional devices.

Cardiovascular screening of Olympic athletes reported by chief medical officers of the Rio 2016 Olympic Games.

OBJECTIVE: The IOC recommends periodic cardiovascular screening of athletes, but the adoption of these recommendations is unknown. The purpose of this investigation was to evaluate and compare cardiovascular screening practices of countries participating in the Rio 2016 Olympic Games. METHODS: A list of chief medical officers (CMOs) was compiled by the IOC during the 2016 Olympic Games. CMOs were requested to complete an online survey about cardiovascular screening of their countries' Olympic athletes. Comparisons of screening practices were made by categorising countries by continent, gross domestic product (GDP) per capita and size of athlete delegation. RESULTS: CMOs for 117/207 (56.5%) countries participating in the 2016 Olympic Games were identified. 94/117 countries (80.3%) completed the survey, representing 45.4% of all countries and 8805/11 358 (77.5%) of all 2016 Olympic athletes. Most of the countries surveyed (70.2%) perform annual cardiovascular screening. Among the survey respondents, all or most athletes from each country were screened at least once with the following components: personal history (86.2% of countries), family history (85.1%), physical examination (87.2%), resting ECG (74.5%), echocardiogram (31.9%) and stress test (30.8%). Athletes were more likely to be screened with ECG in countries with relatively larger athlete delegation (OR 2.05, 95% CI 1.10 to 3.80, p=0.023) and with higher GDP per capita (OR 1.69, 95% CI 1.11 to 2.57, p=0.014). CONCLUSION: Most of the responding countries perform annual cardiovascular screening of Olympic athletes, but there are differences in the components used. Athletes from countries with larger athlete delegations and higher GDP per capita were more likely to be screened with ECG.

The primary care sports medicine fellowship: American Medical Society for Sports Medicine proposed standards of excellence.

The American Medical Society for Sports Medicine recognises a need to provide direction and continually enhance the quality of sports medicine fellowship training programmes. This document was developed to be an educational resource for sports medicine physicians who teach in a 1-year primary care sports medicine fellowship training programme. It is meant to provide high standards and targets for fellowship training programmes that choose to re-assess their curriculum and seek to make improvements.

Nine-year study of US high school soccer injuries: data from a national sports injury surveillance programme.

BACKGROUND: Research on high school soccer injury epidemiology is sparse. AIM: To describe high school soccer injury rates, trends and patterns by type of athlete exposure (AE), position and sex. METHODS: This descriptive epidemiological study used data from a large national high school sports injury surveillance programme to describe rates and patterns of soccer-related injuries including concussion sustained from 2005/2006 to 2013/2014. Injury rates are calculated per 1000 AEs. RESULTS: Overall, 6154 soccer injuries occurred during 2 985 991 AEs; injury rate=2.06 per 1000 AEs. Injury rates were higher during competition (4.42) than practice (1.05; rate ratio (RR)=4.19; 95% CI 3.98 to 4.41), and in girls (2.33) than boys (1.83; RR=1.27, 95% CI 1.21 to 1.34). Boys' non-concussion injury rates decreased significantly (p=0.001) during the study period while reported concussion rates increased significantly (p=0.002). Girls' non-concussion rates were relatively stable and reported concussion rates increased significantly (p=0.004). Player-player contact was the injury mechanism that led to the most competition injuries (injury proportion ratio (IPR)=2.87; 95% CI 2.57 to 3.21), while non-contact injuries were the most common mechanisms among practice injuries (IPR=2.10; 95% CI 1.86 to 2.38). Recovery from concussion was >7 days in a third of the cases. Injury patterns were similar between sexes with respect to position played and location on the field at the time of injury. CONCLUSIONS: High school soccer injury rates vary by sex and type of exposure, while injury patterns are more similar across sexes. Reported concussion rates increased significantly over the study period in male and female athletes.

Psychological impact of electrocardiogram screening in National Collegiate Athletic Association athletes.

PURPOSE: Determine the psychological impact of false-positive ECG screening in National Collegiate Athletic Association (NCAA) athletes. METHODS: Athletes representing seven NCAA institutions received a standardised history, physical examination and ECG interpreted using the 2013 Seattle Criteria. Assessments of health attitudes, anxiety and impact of screening on sport were conducted using validated prescreen and postscreen measurements. RESULTS: 1192 student-athletes participated (55.4% male, median age 19 years, 80.4% Caucasian). 96.8% of athletes had a normal cardiovascular screen, 2.9% had a false-positive ECG and 0.3% were diagnosed with a serious cardiac condition. Prior to screening, 4.5% worried about potentially harbouring cardiac disease and 70.1% preferred knowing about an underlying condition, rather than play sports without this knowledge. There was no difference in anxiety described by athletes with a normal versus false-positive screen (p=0.369). Reported anxiety levels during screening also did not differ when analysed by different gender, race, division of play or sport. Athletes with normal and false-positive screens had similar levels of satisfaction (p=0.714) and would recommend ECG screening to other athletes at similar rates (p=0.322). Compared with athletes with a normal screen, athletes with false-positive results also reported feeling safer during competition (p>0.01). In contrast, athletes with false-positive screens were more concerned about the possibility of sports disqualification (p<0.001) and the potential for developing a future cardiac condition (p<0.001). CONCLUSIONS: Athletes with a false-positive ECG do not experience more anxiety than athletes with a normal screen but do express increased concern regarding sports disqualification and the development of a cardiac disorder. These findings do not justify avoiding advanced cardiovascular screening protocols. Further understanding of athlete experiences could better prepare the practising physician to counsel athletes with an abnormal ECG.
