RESUMO
OBJECTIVE: To determine the effect of an educational workshop on adherence to neuromuscular training (NMT) among high-school coaches. DESIGN: Cluster-randomized controlled trial. SETTING: High school. PARTICIPANTS: A total of 21 teams in 8 high schools (unit of randomization) were randomized to the intervention or control group. Twelve boys' and 9 girls' teams in a variety of sports were enrolled. INTERVENTION: Coaches in the intervention group participated in a 60-minute education workshop to teach effective implementation of a NMT program and also received print materials. Coaches in the control group received the same print materials. MAIN OUTCOME MEASURES: Eight data collectors were trained to observe each team's practice/game 2 to 3 times a week. They completed a study questionnaire to identify the NMT exercise and whether the coach (1) delivered exercise instructions and (2) provided alignment cues (both yes/no). RESULTS: A total of 399 practices/games were observed over 2 seasons. A greater proportion of coaches in the intervention group provided alignment cues to correct improper technique compared with the control group {difference = 0.04 [95% confidence interval (CI), 0.01-0.07], P = 0.006}. There was a similar proportion of coaches in the intervention and control groups who provided exercise instructions [difference = 0.01 (95% CI, -0.02 to 0.04), P = 0.44]. More coaches in the intervention group completed a full NMT program [OR = 4.62 (1.22, 17.50), P = 0.02]. CONCLUSIONS: Coach education can improve adherence to a NMT program and delivery of alignment cues. Coaches should receive in-person training on NMT and how to deliver alignment cues to their athletes while performing the exercises.

BACKGROUND: There has been an increase in the use of electronic systems to collect patient-reported outcome measures. There is limited data on the added value of electronic reporting on increasing patient response proportions and little knowledge of which patients are more likely to respond. QUESTIONS/PURPOSES: (1) What proportion of patients completed patient-reported outcome questionnaires at baseline and at 1 year and 2 years of follow-up after shoulder arthroplasty, and what methods did they use to complete these questionnaires (either automated or manual data collection)? (2) What factors were associated with questionnaire completion? METHODS: Our shoulder arthroplasty registry from a high-volume, tertiary care center implemented an electronic platform to collect patient-reported outcomes. A total of 2128 patients underwent shoulder arthroplasty between 2016 and 2019. Patients without an email address on file were excluded; 90% (1907 of 2128) of patients were included in the study. The population was 50% women (954 of 1907) with a mean age of 67 ± 9 years. A query was performed to determine whether patients completed questionnaires by either automated or manual data collection at baseline and 1 year and 2 years of follow-up after shoulder arthroplasty. In a logistic regression analysis, patient factors (such as demographics, education, and living arrangements) were evaluated for their association with whether patients completed these questionnaires. RESULTS: The proportion of questionnaire completion at baseline, 1 year, and 2 years were 72% (1369 of 1907), 47% (456 of 972), and 33% (128 of 393), respectively. Of the patients who completed their questionnaires, 63% (868 of 1369) did so through automated emails at baseline, 84% (381 of 456) did so at 1 year, and 81% (103 of 128) did so at 2 years. The remainder completed their questionnaires through manual data collection with a research assistant: 37% (501 of 1369) at baseline, 16% (75 of 456) at 1 year, and 19% (25 of 128) at 2 years. After controlling for potentially confounding variables like patient demographics, college education, and living arrangements, women were less likely to complete baseline questionnaires than men (odds ratio 0.78 [95% confidence interval 0.62 to 0.99]; p = 0.04), and white patients (OR 1.6 [95% CI 1.05 to 2.44]; p = 0.03) were more likely than nonwhite patients to have complete baseline questionnaires. At 2 years of follow-up, patients with a college education (OR 2.06 [95% CI 1.14 to 3.71]; p = 0.02), those who lived alone (OR 2.11 [95% CI 1.13 to 3.94]; p = 0.02), and those who had higher baseline Shoulder Activity Scale scores (OR 1.05 [95% CI 1.00 to 1.11]; p = 0.04) were more likely to have complete questionnaires than those without a college education, those who lived with other people, and those with lower SAS scores, respectively. CONCLUSION: The challenges of adopting an online platform include low follow-up proportions and the need for manual assistance by a research assistant to increase patient completion of questionnaires. CLINICAL RELEVANCE: The knowledge of which patient characteristics are associated with a higher likelihood of completing questionnaires has implications for targeted follow-up or representative sampling of the population in a registry. Populations that are less likely to respond may require more effort to reach to prevent exacerbating health outcome disparities. Random sampling with upweighting of hard-to-reach populations may also provide a solution to achieve a representative population of patients undergoing shoulder arthroplasty.

BACKGROUND: There is a high incidence of performance-related musculoskeletal disorders in musicians that may be reduced via education programs. However, the efficacy of formalized injury prevention programs has not been rigorously studied. PURPOSE: To assess the feasibility and effect of a formalized injury prevention education workshop on incidence and severity of musculoskeletal pain in a cohort of musician-students attending an intensive summer music festival compared to controls. STUDY DESIGN: Randomized-controlled-pilot trial. METHODS: Musicians at an 8-week long intensive summer festival were randomized to an intervention (workshop) or control group. Workshop attendees participated in a 90-minute session of injury prevention strategies. Musculoskeletal outcome data were collected at the start and end of the festival. Outcomes included presence of musculoskeletal pain, adherence level, and sub-scales of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians. RESULTS: A total of 57 musician-students (ages 17-30, 23 females) participated in the study, and 48(84%) completed the study. Seventy-five percent of workshop participants reported adherence over 8 weeks. At baseline, 84% of participants reported a history of playing-related pain, and 47% recent or current pain. Participants played a range of instruments (50% string, 34% piano, 16% woodwind/brass). At baseline, average weekly reported playing time was 39 hours (±11). At follow-up, reported pain decreased by 32% in the intervention group and increased by 8% in controls (P < .01). Pain interference scores were lower (Post - Pre = -4.58, 95% CI -9.26 to 0.11, P = .055). There was no statistically significant difference between groups for pain intensity. CONCLUSIONS: The high compliance and willingness to participate suggests that injury prevention education implementation is feasible. Our preliminary findings suggest a positive effect on pain incidence and pain interference in the intervention group. Future studies will examine the relationship between adherence levels and injury rates in a larger cohort and identify obstacles to implementation.

BACKGROUND: There is ample evidence to suggest sex- and gender-based differences in the incidence of sports-related concussions. The mechanisms of concussion may vary between male and female athletes and contribute to this observed difference. Understanding the underlying etiology by pooling data from primary studies across different settings and sport types will inform interventions that can reduce concussion rates. QUESTIONS/PURPOSES: Specifically, we asked: (1) In which sports are female athletes less likely to experience concussions from player contact? (2) In which sports are female athletes more likely to experience concussions because of ball or equipment contact? METHODS: PubMed, EMBASE, and Cochrane Library databases were searched to identify articles published from January 2000 to December 2018. Ten studies met the inclusion criteria, which were studies that reported concussion incidence by mechanism for both male and female athletes. Exclusion criteria included non-English studies, conference abstracts, and studies on non-sports related concussions. The sports represented by the 10 studies included ice hockey (n = 4), soccer (n = 5), basketball (n = 4), baseball/softball (n = 4), and lacrosse (n = 5). The rate ratio was calculated as the incidence rate in female athletes/male athletes for each concussion mechanism or activity. Data were pooled using the DerSimonian-Laird random-effects model. Study quality was assessed with the Newcastle-Ottawa Scale. RESULTS: Female athletes were at lower risk of player-contact-induced concussions in lacrosse (pooled rate ratio 0.33 [95% CI 0.25 to 0.43]; p < 0.001), basketball (pooled rate ratio 0.86 [95% CI 0.76 to 0.97]; p = 0.01), ice hockey (pooled rate ratio 0.64 [95% CI 0.56 to 0.73]; p < 0.001), soccer (pooled rate ratio 0.70 [95% CI 0.66 to 0.75]; p < 0.001), and soccer heading (pooled rate ratio 0.80 [95% CI 0.72 to 0.90]; p < 0.001); in these sports, men were at higher risk of concussions from player contact. Female athletes were more likely to experience concussions because of ball or equipment contact in lacrosse (pooled rate ratio 3.24 [95% CI 2.10 to 4.99]; p < 0.001), soccer (pooled rate ratio 2.04 [95% CI 1.67 to 2.49]; p < 0.001), and soccer heading (pooled rate ratio 2.63 [95% CI 1.84 to 3.77]; p < 0.001). CONCLUSIONS: The mechanism or activity underlying concussions differs between male and female athletes across different sports. This finding remains the same regardless of whether there are rule differences between the men's and women's games. The implementation of other interventions are required to further ensure player safety, including protective head equipment, concussion prevention training, or rules limiting player contact in the men's game. LEVEL OF EVIDENCE: Level III, retrospective study.

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.

INTRODUCTION: We described trends for sexually transmitted infections (STI) among gay/bisexual men in British Columbia, Canada, using a sentinel site surveillance approach. METHODS: Using data from an electronic charting system, we included gay/bisexual men who visited high-volume STI clinics from 2000 to 2013. Diagnosis rates and incidence density were calculated for chlamydia, gonorrhea, syphilis, HIV, hepatitis C, genital herpes, and genital warts. Incidence density was estimated among repeat testers who converted from a negative to positive test result. We also conducted Poisson regression analysis to determine factors that were associated with increased incidence rates. RESULTS: A total of 47,170 visits were identified for gay/bisexual men during our time frame. The median age was 34 years (interquartile range, 27-43 years), and most clients were seen in Vancouver. Although trends for most STI were stable, diagnoses of gonorrhea and syphilis have risen steadily in recent years. Coinfection with HIV was associated with higher gonorrhea and syphilis rates in the Poisson regression model. In addition, visiting a Vancouver clinic and younger age were associated with increased incidence. CONCLUSIONS: Our clinic-based sentinel surveillance system found increasing trends for gonorrhea and syphilis among gay/bisexual men but not for other STI in British Columbia. Further investigation is required to explore the syndemic effects of syphilis, gonorrhea, and HIV. This new platform will be a valuable tool for ongoing monitoring of STI and targeting prevention efforts.

BACKGROUND: The absence of a gold standard, i.e., a diagnostic reference standard having perfect sensitivity and specificity, is a common problem in clinical practice and in diagnostic research studies. There is a need for methods to estimate the incremental value of a new, imperfect test in this context. METHODS: We use a Bayesian approach to estimate the probability of the unknown disease status via a latent class model and extend two commonly-used measures of incremental value based on predictive values [difference in the area under the ROC curve (AUC) and integrated discrimination improvement (IDI)] to the context where no gold standard exists. The methods are illustrated using simulated data and applied to the problem of estimating the incremental value of a novel interferon-gamma release assay (IGRA) over the tuberculin skin test (TST) for latent tuberculosis (TB) screening. We also show how to estimate the incremental value of IGRAs when decisions are based on observed test results rather than predictive values. RESULTS: We showed that the incremental value is greatest when both sensitivity and specificity of the new test are better and that conditional dependence between the tests reduces the incremental value. The incremental value of the IGRA depends on the sensitivity and specificity of the TST, as well as the prevalence of latent TB, and may thus vary in different populations. CONCLUSIONS: Even in the absence of a gold standard, incremental value statistics may be estimated and can aid decisions about the practical value of a new diagnostic test.

CONTEXT: Mental health is a growing area of concern for elite athletes. OBJECTIVE: To determine the sex differences in mental health symptoms in elite athletes. DATA SOURCES: PubMed, EMBASE, and Cochrane Library databases were used. STUDY SELECTION: Included studies included comparisons of mental health symptoms of athletes by sex. STUDY DESIGN: Systematic review and meta-analysis were conducted following the PRISMA guidelines. LEVEL OF EVIDENCE: Level 2a. DATA EXTRACTION: The rate ratio (RR) was calculated as the rates in female and male athletes. Data were pooled using a random-effects model. RESULTS: Of 1945 articles identified, 60 articles were included. Male athletes reported higher alcohol misuse (RR, 0.74; CI, 0.68-0.80), illicit drug abuse (RR, 0.82; CI, 0.75-0.89), and gambling problems (RR, 0.14; CI, 0.08-0.25). Female athletes reported higher overall anxiety (RR, 1.17; CI, 1.08-1.27), depression (RR, 1.42; CI, 1.31-1.54), distress (RR, 1.98; CI, 1.40-2.81), and disordered eating (RR, 2.19; CI, 1.58-3.02). Sleep disturbances were reported at similar rates in male and female athletes (RR, 1.13; CI, 0.98-1.30). CONCLUSION: Female and male athletes have significant differences in reported mental health symptoms. Female athletes are more likely to report anxiety, depression, distress, and disordered eating, while male athletes report more alcohol misuse, illicit drug abuse, and gambling. Monitoring and evaluation of mental health is a necessary part of any sport, including access to resources. Longitudinal studies following athletes over time to determine the development and causation for mental health symptoms should be included in future research directions.
RESUMO
OBJECTIVES: Studies on adherence to neuromuscular training (NMT) for anterior cruciate ligament (ACL) injury prevention are frequently biased due to the use of self-reporting by coaches or the athletes themselves. Few NMT studies use data collectors (aside from the athletes or the individuals administering the NMT program) to decrease bias when assessing the adherence of coaches and sports teams. We hypothesized that the use of a data collector who is independent of the team to evaluate adherence to NMT programs would be reliable. METHODS: In a prior a cluster-randomized controlled trial evaluating adherence to NMT training trial, twelve boys' and nine girls' high school athletic teams in a variety of sports were enrolled. Eight data collectors (unaffiliated with the NMT program) were hired specifically to record adherence of the athletes to the NMT exercises at each team's warm-ups 2-3 times a week, prior to practices and games. In addition to the data collectors, a control group of independent observers made visits throughout the season to also record adherence (solely for the purpose of this study, alongside the data collectors and in the same fashion) in order to evaluate the data collectors' performance and determine inter-observer reliability. The inter-observer reliability between data collectors and independent observers was measured using the Kappa statistic. RESULTS: A total of 399 warm-ups for practices or games were observed by data collectors to obtain adherence data. Independent observers also measured adherence at 58 practices or games for inter-observer reliability. Exercise instruction and alignment cues for 29 different exercises were analysed. The Kappa values ranged from 0.63 to 1.0, indicating substantial to perfect agreement. The overall Kappa values of 0.89 and 0.90 for exercise instruction and alignment cues, respectively, indicated almost perfect agreement. CONCLUSION: The use of a data collector who is independent of the team to evaluate adherence to NMT programs (rather than athlete or coach self-reporting), was shown to be a reliable method for measurement of adherence in studies of NMT for injury prevention. Avoiding self-reporting in adherence research to NMT training may decrease bias. LEVEL OF EVIDENCE: I.

INTRODUCTION: Interferon γ release assays (IGRAs) are increasingly used for tuberculosis (TB) infection, but their incremental value beyond patient demographics, clinical signs and conventional tests for active disease has not been evaluated in children. METHODS: The incremental value of T-SPOT.TB was assessed in 491 smear-negative children from two hospitals in Cape Town, South Africa. Bayesian model averaging was used to select the optimal set of patient demographics and clinical signs for predicting culture-confirmed TB. The added value of T-SPOT.TB over and above patient characteristics and conventional tests was measured using statistics such as the difference in the area under the receiver operating characteristic curve (AUC), the net reclassification improvement (NRI) and the integrated discrimination improvement (IDI). RESULTS: Cough longer than 2 weeks, fever longer than 2 weeks, night sweats, malaise, history of household contact and HIV status were the most important predictors of culture-confirmed TB. Binary T-SPOT.TB results did not have incremental value when added to the baseline model with clinical predictors, chest radiography and the tuberculin skin test. The AUC difference was 3% (95% CI 0% to 7%). Using risk cut-offs of <10%, 10-30% and >30%, the NRI was 7% (95% CI -8% to 31%) but the CI included the null value. The IDI was 3% (95% CI 0% to 11%), meaning that the average predicted probability across all possible cut-offs improved marginally by 3%. CONCLUSIONS: In a high-burden setting, the T-SPOT.TB did not have added value beyond clinical data and conventional tests for diagnosis of TB disease in smear-negative children.

BACKGROUND: Neuromuscular training (NMT) has demonstrated efficacy as an intervention to decrease the risk of anterior cruciate ligament injuries and improve sports performance. The effect of this training on the mechanisms that contribute to improved physical performance has not been well defined. HYPOTHESIS: Athletes in the NMT group will have better mechanisms of fundamental movements and agility tests that may contribute to improved sports performance. STUDY DESIGN: Prospective cohort study. LEVEL OF EVIDENCE: Level 2. METHODS: Eight high school teams (111 athletes, 53% male, mean age 16 years) participated, with half performing NMT. Physical performance was measured using the dorsaVi ViPerform system, a US Food and Drug Administration-cleared wireless sensor system. Agility was assessed using a timed 3-cone test. Independent sample t tests were used to compare differences between the intervention and control groups. RESULTS: Matched pre- and postseason data were collected from 74 athletes after excluding athletes with injury and those lost to follow-up. Significant improvements were observed in the NMT group for loading/landing speed ratios during a single-leg hop test (right lower extremity = -0.19 [-0.37, 0.03], P = 0.03 and left lower extremity = -0.27 [-0.50, -0.03], P = 0.03). The control group had lower ground reaction forces compared with the NMT group (P < 0.02), while significant improvements were found in the NMT group for initial peak acceleration (P < 0.02) and cadence (P = 0.01) during a straight-line acceleration/deceleration test. For the 3-cone agility test, the postseason time decreased compared with preseason in the NMT group, whereas the time for the control group increased (-0.37 s vs 0.14 s, P < 0.00). CONCLUSION: The results demonstrate that NMT administered by sports medicine clinicians can significantly improve some physical performance of fundamental movements in high school athletes. CLINICAL RELEVANCE: Coaches should be trained to effectively deliver NMT in order to improve sports performance.

Background: Athletes who participate in sports that involve cutting and pivoting movements are particularly susceptible to anterior cruciate ligament (ACL) injury. Preventing this injury is the best way to combat its health consequences and costs. There may be a dose-response relationship between adherence and injury reduction. Purpose: We sought to examine whether athletes' adherence to injury prevention programs (IPPs) is associated with reductions in ACL and lower extremity (LE) injuries. Methods: We conducted a systematic review of the PubMed, EMBASE, and Cochrane Library databases, searching for studies published between 2011 and 2021. Studies were included if they reported on the use of an ACL IPP compared with a control group and recorded the rate of injuries to calculate a rate ratio, as well as adherence to the program as a percentage of sessions performed. For the meta-analysis, the rate ratios were pooled using the DerSimonian-Laird random-effects model. Results: For the 15 studies included (11 randomized controlled trials and 4 cohort studies), the random-effects model grouped athletes' adherence to an IPP as high (76% or more of the sessions), moderate (51%-75% of the sessions), and low (50% or fewer of the sessions). We found that athletes with the highest level of IPP adherence had a significantly lower incidence of ACL injury. The rate ratios for moderate and low adherence did not demonstrate a reduced incidence of ACL injury. Injury prevention program participation was also associated with a decrease in LE injury rates. Conclusion: This systematic review and meta-analysis found that athletes with high adherence to IPPs had reduced rates of ACL and LE injuries. Our findings suggest that educating coaches and athletes on the dose-dependent benefits of IPPs may promote the routine incorporation of these programs into warm-up sessions to decrease the risk of ACL and LE injuries.
RESUMO
OBJECTIVES: Women are under-represented in the sports literature despite increasing rates of sports participation. Our objective was to investigate the risks and benefits of an elite women's soccer career in five health domains: general, musculoskeletal, reproductive endocrinology, post-concussion, and mental. METHODS: An online survey was distributed to retired US college, semi-professional, professional, and national team soccer players using personal networks, email, and social media. Short validated questionnaires were used to evaluate the health domains, including the Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numerical Evaluation (SANE), Post-Concussion Symptom Scale (PCSS), and Patient Health Questionnaire (PHQ). RESULTS: A total of 560 eligible players responded to the survey over a 1-year period. The highest competitive levels were 73% college, 16% semi-professional, 8% professional, and 4% national team. The mean number of years since retirement was 12 (SD = 9), and 17.0% retired for involuntary reasons. The mean SANE scores (0-100 scale as percentage of normal) were knee = 75% (SD = 23), hip = 83% (SD = 23), and shoulder = 87% (SD = 21). The majority (63%) reported that their current activity level included participation in impact sports. A substantial proportion of players reported menstrual irregularities during their careers: 40% had fewer periods with increasing exercise and 22% had no periods for ≥ 3 months. The players (n = 44) who felt that post-concussion symptoms were due to soccer reported more time-loss concussions (F[2] = 6.80, p = 0.002) and symptom severity (F[2] = 30.26, p < 0.0001). Players who recently retired (0-5 years) reported the highest anxiety/depression scores and lowest satisfaction rates compared with those who retired 19+ years ago. CONCLUSION: Health concerns include musculoskeletal injuries, post-concussion symptoms, and lower mental health in the early years following retirement. This comprehensive survey provides initial results that will lay the foundation for further analyses and prioritize research studies that can help all female athletes.

BACKGROUND: Health disparities related to concussions have been reported in the literature for certain minority populations. Given the significant impact of concussions on long- and short-term function, the mitigation of barriers to accessing care is an important public health objective. OBJECTIVE: To determine if racial and ethnic disparities exist in patients who seek care for concussions compared to a control group with orthopedic ankle injuries (sprains and fractures) to minimize confounding factors that predispose to injury. DESIGN: Cohort study. SETTING: Single institution between February 2016 and December 2020. PATIENTS: A retrospective review of electronic medical records was completed for patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for concussion, ankle sprain, and ankle fracture. A total of 10,312 patients were identified: 1568 (15.2%) with concussion, 4871 (47.3%) with ankle sprain, and 3863 (37.5%) with ankle fracture. INTERVENTIONS: Patients were stratified by demographic factors, including sex, ethnicity, race, and insurance type. MAIN OUTCOME MEASURES: Diagnosis of concussion. RESULTS: The concussion group was the youngest (28.3 years ± 18.0) and had the fewest females (53.1%) compared to the ankle sprain (35.1 years ± 19.7; 58.7%) and fracture groups (44.1 years ± 21.3; 57.3%). The concussion group had a smaller proportion of Hispanic patients than the ankle sprain group (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.55-0.92, p = .010) and fracture group (OR 0.58, 95% CI 0.44-0.75, p = <.001). In addition, the concussion group was less likely to be Asian (OR 0.70, CI 0.52-0.95, p = .023) than the sprain group and less likely to be Black/African American than both sprain (OR 0.65, 95% CI 0.46-0.93, p = .017) and fracture groups (OR 0.62, 95% CI 0.43-0.89, p = .010). There were no differences across racial groups between ankle sprains and fractures. Patients with Medicaid/Medicare and self-pay had a higher likelihood of being in the concussion group than those with private insurance. CONCLUSION: Differences in concussion diagnosis may exist between certain demographic groups compared to those with ankle injuries.

OBJECTIVE: To compare concussion incidence in male and female soccer players due to the specific concussion-causing activity. METHODS/DATA SOURCES: PubMed, EMBASE, and Cochrane Library were searched for studies published between January 2000 and February 2020. Search terms included 'sex,' 'gender,' 'sex differences,' 'brain injury,' 'sports,' 'athletes,' 'incidence,' 'epidemiology,' 'symptoms,' and 'injury rate.' Studies that contained data on concussion incidence in soccer and featured comparisons by sex and soccer activity were included. Studies that were not written in English, contained data on non-sports-related concussions, or were conference abstracts were excluded. RESULTS: Six studies were included in this meta-analysis, each of which contributed the number of concussions in males and females for a specific soccer activity. Concussion incidence rates were calculated using athlete-exposures as the denominator and a rate ratio was measured by dividing the concussion rate among female soccer players by the rate among male soccer players. Female soccer players were shown to have a greater rate of concussions from heading [1.65 (95% CI: 1.35, 2.03, p < 0.001)] and goalkeeping [1.63 (95% CI: 1.22, 2.17, p = 0.001)]. There were 3 studies comparing sex differences for general play. While the pooled rate ratio was statistically significant [1.51 (95% CI: 1.12, 2.04), p = 0.007], this result was largely driven by 1 study. CONCLUSION: Concussion incidence rates were significantly higher in female soccer players compared to male players while heading. There is also some evidence to suggest that the incidence is higher for female goalkeepers. Soccer coaches and health care providers need to recognize this sex difference when coaching or treating players.

Childhood TB is difficult to diagnose, since disease tends to be paucibacillary and sputum specimens are not easy to obtain in children. Thus, blood-based immune assays are an attractive option. Systematic reviews of serological assays suggest that these tests produce highly inconsistent estimates of sensitivity and specificity, but much of the serology literature is based on adults. In children, there is insufficient evidence to recommend the use of serological tests for active TB diagnosis. Interferon-gamma release assays (IGRA) do not offer substantial improvements in sensitivity over the TST for the diagnosis of active disease. For latent TB infection, the IGRA correlates well with the exposure gradient and seems to have utility in reducing the number of children who undergo preventive therapy due to false-positive TST. Although IGRAs can be used as evidence of TB infection in children, appropriate specimen collection and microbiological confirmation of TB disease should remain a priority.

Recall bias is a systematic error caused by inaccuracy in reporting past health status and can be a substantial methodological flaw in the retrospective collection of data. Little is known about recall bias following anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to evaluate patients' recall bias regarding preinjury knee function at 2 years after ACLR. METHODS: Patients undergoing ACLR were enrolled in an institutional ACL registry. Preoperatively and at 2 years postoperatively, patients quantified their preinjury knee function on a scale of 0 to 10 (10 = best). Recall bias was quantified as the difference in the reported preinjury function between the 2 time points. The clinical result of ACLR was evaluated according to the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation score. Patients meeting the minimal clinically important difference (MCID) in the IKDC score were considered to have had a good outcome, while patients who did not reach the MCID were considered to have had failure of treatment. Recall bias was compared between the 2 groups. RESULTS: Of 2,109 patients enrolled in the registry, 1,219 were included in the study. Patients with a good outcome remembered their preinjury knee function on a 0-to-10 scale to be better than what they reported at baseline, by a mean difference of 0.40 points (95% confidence interval [CI], 0.22 to 0.58 points). The recall bias was stronger for patients with a poor outcome, who remembered their knee function to be worse than reported at baseline, by a mean difference of -0.81 (95% CI, -1.4 to -0.26). The mean difference in recall between the 2 groups was -1.21 (95% CI, -1.74 to -0.67) (p < 0.0001). CONCLUSIONS: The recall bias of preinjury knee function following ACLR was small and not clinically meaningful for the majority of patients. However, patients with a poor outcome had a clinically relevant and significant recall bias. CLINICAL RELEVANCE: Our findings suggest that patients with a poor outcome have a substantial recall bias. This has clinical relevance when considering treatment effects of revision surgery, whereby the clinical benefit of the treatment might be affected by recall bias.
RESUMO
AIMS: To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty. METHODS: Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution's registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female. RESULTS: The most common comorbidities were obesity (1,256, 69%) and hypertension (990, 55%). Patients with more comorbidities had lower ASES and SAS scores at baseline (p < 0.001). Elixhauser comorbidities continued to negatively impact ASES and SAS scores at one year (p = 0.002) and two-year follow-up (p = 0.002). Patients with more comorbidities reported greater pain interference on PROMIS at baseline (p = 0.007), but not at two years. Higher number of Charlson comorbidities were associated with lower scores on the SF-12 mental component at baseline (p < 0.001) and two years (p = 0.020). Higher number of Elixhauser comorbidities were associated with lower SF-12 physical component scores at baseline (p < 0.001) and two years (p = 0.004). CONCLUSION: Higher number of comorbidities was associated with lower baseline scores and worse outcomes on both shoulder-specific and general health PROMs. The presence of specific comorbidities may be used during shared decision-making to manage expectations for patients undergoing shoulder arthroplasty.

BACKGROUND: Nonoperative treatment after first-time patellar dislocation is the standard of care. There is evidence that certain patients may be at high risk for recurrent instability. The aim of this study was to develop a multivariable model to guide management of patients based on their individual risk of recurrent dislocation. METHODS: A multivariable model was developed using 291 patients from 4 institutions to identify which patients were at higher risk for recurrent patellar dislocation within 2 years. This model was informed by a univariable logistic regression model developed to test factors based on the patient's history, physical examination, and imaging. The discriminatory ability of the model to classify who will or will not have a recurrent dislocation was measured using the area under the receiver operating characteristic curve (AUC). RESULTS: Age, a history of a contralateral patellar dislocation, skeletal immaturity, lateral patellar tilt, tibial tubercle-trochlear groove (TT-TG) distance, Insall-Salvati ratio, and trochlear dysplasia were the most important factors for recurrent patellar dislocation. Sex, mechanism of injury, Caton-Deschamps ratio, sulcus angle, inclination angle, and facet ratio were not factors for recurrent dislocation. The overall AUC for the multivariable model was 71% (95% confidence interval [CI]: 64.7% to 76.6%). CONCLUSIONS: Optimizing the management of lateral patellar dislocation will improve short-term disability from the dislocation and reduce the long-term risk of patellofemoral arthritis from repeated chondral injury. This multivariable model can identify patients who are at high risk for recurrent dislocation and would be good candidates for early operative treatment. Further validation of this model in a prospective cohort of patients will inform whether it can be used to determine the optimal treatment plan for patients presenting with an initial patellar dislocation. Until validation of the model is done with new patients, it should not be used in clinical practice. LEVEL OF EVIDENCE: Prognostic Level III.
