The Impact

Objectives: Concussion injuries are common in professional football players, however the impact on player careers remains unclear. The purpose of this study was to quantify the effect of concussions on professional football player performance. Methods: Concussion data from the National Football League was collected for a period of four seasons (2012-2015) for running backs and wide receivers. Demographic variables (age, experience, position, time to return, yearly total yards and touchdowns) were recorded. Power ratings (total yards divided by 10 plus touchdowns multiplied by 6) were calculated for the injury season as well as for the 3 seasons before and after the injury. A control group consisted of running backs and wide receivers without an identified concussion injury who competed in the 2014 season. Results: One hundred and eighteen running backs and wide receivers sustained a concussion over a 4-season period, 25 players (21%) never returned to a National Football League game. Players were able to return in an average of 18.5 ± 8.2 days, missing 1.6 ± 1.0 games. For 18 players with a minimum total power rating of (sum of 4 seasons) of 200 points, power rating per game decreased 43.4 ± 0.4 points from three seasons prior to the concussion to three years postinjury. This change in performance was not statistically significant (P=0.422) when compared with the change for the 343 control players. Conclusion: Over one fifth of National Football League running backs and wide receivers who sustain a concussion never return to play in a game. On return to competition, player performance of injured players reduced from before injury, however there was no difference compared to controls.

Player Performance

Background: Concussion injuries are common in professional football players; however, their effect on player performance remains unclear. Purpose: To quantify the effect of concussions on the performance of running backs and wide receivers in professional football players. Study Design: Cohort study; Level of evidence, 3. Methods: Concussion data from the National Football League were collected for a period of 4 seasons (2012-2015) for running backs and wide receivers. Age, experience, position, time to return to play, yearly total yards, and touchdowns were recorded. A power rating (total yards divided by 10 plus touchdowns multiplied by 6) was calculated for each player’s injury season as well as for the 3 seasons before and after their respective injury. A control group of running backs and wide receivers without an identified concussion injury who competed in the 2012 season was assembled for comparison. Player performance up to 3 seasons before and after the injury season was examined to assess acute and longitudinal changes in player performance. Results: A total of 38 eligible running backs and wide receivers sustained a concussion during the study period. Thirty-four (89%) players were able to return to competition in the same season, missing an average of 1.5 ± 0.9 games; the remaining 4 players returned in the subsequent season. Power ratings for concussed players were similar to those of controls throughout the study period. Concussed players did not suffer an individual performance decline upon returning within the same season. Furthermore, no significant difference in change of power rating was observed in concussed players in the acute (±1 year from injury; −1.2 ± 4.8 vs –1.1 ± 3.9, P = .199) or chronic (±3 years from injury; –3.6 ± 8.0 vs –3.0 ± 4.5, P = .219) setting compared with controls. All concussed players successfully returned to competition in either the index or next season. Conclusion: A high rate of National Football League running backs and wide receivers are able to return to play after a concussion injury. These players were found to perform at a similar level in both the acute and long-term period after concussion.

Player Performance

Background: Sports-related concussion (SRC) rates are higher in American football than any other sport; therefore, the effects of SRCs on professional football players is a prevalent topic. Previous research has shown that sustaining an SRC has negative financial and overall career outcomes for athletes and may cause performance decrements after an athlete returns to play, however, the results of previous research regarding athlete performance after returning from an SRC are mixed. While some studies found that player performance in the National Football League (NFL) was unaffected upon returning from an SRC, evidence also suggests significant scoring reductions in offensive players. Although previous research has found that NFL running backs and wide receivers perform at levels similar to their performance before sustaining an SRC, little is known about quarterback performance after an SRC. There is also evidence that SRCs decrease neurocognitive performance, a quality that is crucial, especially for quarterbacks. Objective: The purpose of this study is to examine changes in NFL quarterback performances upon return to play from an SRC. Method: Quarterback ratings (QBRs) and concussion data from 2012-2015 were used to determine if changes occurred in NFL quarterback performance following an SRC. Results: QBRs decreased by 13.3 points (p = 0.014) after quarterbacks return from an SRC. Conclusions: Changes in on-field performance for NFL quarterbacks after sustaining an SRC could be the result of neurocognitive decrements that impact quick reaction and decision-making skills, which may have greater impacts on quarterbacks than other positions.

Anterior Cruciate

Background: Anterior cruciate ligament (ACL) ruptures are potentially career-threatening injuries to National Football League (NFL) skill position players. A 2006 study showed a return-to-play (RTP) rate of 79% for NFL running backs (RBs) and wide receivers (WRs). Since then, a number of factors affecting RTP, including style of play as well as rules regarding hits to the head, have changed how defensive players tackle offensive ball carriers. Purpose/Hypothesis: To determine whether the RTP rate for RBs and WRs in the NFL has changed since data were collected in the 2000s. Additionally, we evaluated player performance before and after ACL reconstruction (ACLR). We hypothesized that there will be a lower RTP rate than previously reported as well as a decrease in performance statistics after ACLR. Study Design: Descriptive epidemiology study. Methods: Publicly available NFL injury reports between the 2009-2010 and 2015-2016 seasons were utilized for RBs and WRs who underwent ACLR. Successful RTP was indicated by playing in at least 1 NFL game after reconstruction. Position-specific performance statistics from before and after reconstruction were gathered for these players, and the RTP players were compared against the players who did not RTP (dnRTP group). Pre- and postinjury performance measures were also compared against a matched control group of NFL RBs and WRs who had not sustained an ACL injury. Results: Overall, 61.8% of players (64.5% of RBs, 60% of WRs) returned to play at a mean of 13.6 months. Prior to injury, the RTP group had played in significantly more career games and had significantly more rushes and receptions per game than the dnRTP group; however, there was no significant difference in performance after ACLR. The WR RTP group had significantly decreased performance in all measured categories when compared with the control group. Conclusion: Our study found a lower RTP rate in RBs and WRs than previous studies conducted in the early 2000s. WRs who achieved RTP had decreased performance when compared with noninjured controls.

Background: The effect of concussions on professional athletes has been investigated in many sports. However, few studies have evaluated concussions in National Basketball Association (NBA) players. Hypothesis: We hypothesized that concussion incidence has increased, yet the return-to-play (RTP) rate will remain high following the institution of the NBA concussion policy (NBACP). We also hypothesized that the incidence of repeat concussions will be similar to first occurrences and that player performance and game availability will not be significantly affected by sustaining a concussion. Study Design: Descriptive epidemiology study. Methods: Publicly available records were searched to identify all concussions from NBA seasons 1999-2000 to 2017-2018. Player demographics and information regarding career history were tabulated. Incidence of concussion and RTP timing were evaluated before and after institution of the NBACP (2011). Minutes per game and game score per minute were evaluated pre- versus postconcussion. Player availability and performance were also compared with an age-, body mass index–, position-, and experience-matched control group of players who did not sustain a concussion. Results: A total of 189 concussions were reported in the NBA from 1999 to 2018, with a mean ± SD incidence of 9.7 ± 7.3 concussions per season. Following implementation of the NBACP, incidence significantly increased from 5.7 ± 2.8 to 16.7 ± 7.5 concussions per season ( P = .007). All players returned to play following first-time concussion after missing 7.7 ± 8.6 days and 3.5 ± 4.1 games. RTP time was not significantly different after implementation of the NBACP (games missed, P = .24; days missed, P = .27), and there was no difference in concussion-free time interval ( P = .29). Game score per minute and minutes per game were not significantly affected by sustaining a concussion (both P > .05). Conclusion: Concussion incidence in NBA players is approximately 17 instances per season since the 2011 institution of a league-wide concussion policy. The number of reported concussions significantly increased following the policy, in line with trends seen in other professional sports leagues. Players have retained a high rate of RTP after 3 to 4 missed games. Player performance and availability are not affected by sustaining a concussion following successful RTP.

Category: Ankle, Sports Introduction/Purpose: While much less common than ankle sprains and other sports injuries, Achilles tendon ruptures have represented unexpected and potentially career-altering injuries for professional football athletes in the National Football League (NFL). Over the past decade, the technique for surgical repair of the ruptured Achilles tendon has evolved. Mini-open and percutaneous techniques have become more common, allowing for the minimization of wound complications and expediting the rehabilitation of athletes. Therefore, the objectives of this study were to update the epidemiology of Achilles tendon ruptures in the NFL, and to analyze how recovery and post-injury performance of professional football players with this injury have progressed in the last two decades. Methods: Several online sources including NFL news and injury reports, player registries, and player statistic databases were cross-referenced to conduct a retrospective identification of all NFL players sustaining complete Achilles tendon ruptures during the 2010-2015 NFL seasons. Yearly player performance statistics were also obtained and recorded for both offensive and defensive players. A power rating formula and “approximate value” algorithm, commonly used to evaluate player production, were borrowed to calculate yearly Offensive and Defensive performance metrics for each injured player. These calculated measurements were used to quantify both offensive and defensive player performance up to 3 seasons before and after their respective Achilles tendon rupture injuries, allowing for each player to serve as his own control. Results: 78 Achilles tendon ruptures were identified in professional football players during the 2010-2015 NFL seasons. 58% of these injuries occurred during the preseason. Of those that suffered an Achilles tendon rupture, 26% did not ever return to play in the NFL. Players who did return to play in the NFL took an average of 9 months to recover after the date of injury. Across all positions, there was a net decrease in power ratings by 22% and a net decrease in approximate value by 23% over 3 years following player return after Achilles tendon rupture. Across all positions, running backs saw the biggest decrease in production with a 78% decrease over 3 years post-injury in both power ratings and approximate value. Conclusion: While the incidence of Achilles tendon ruptures in NFL players, especially in the preseason, has increased substantially, more players are returning to play after injury and with better post-injury performance as compared to the previous two decades. These injuries should still be considered potentially career-altering as 26% of players never return to play after Achilles tendon ruptures and there is still a net decrease in power-ratings by 22% for those who do return. However, these numbers optimistically suggest that advancements in treatment protocol and rehabilitation are resulting in faster recovery and improved performance after Achilles tendon ruptures in NFL players.

The Impact

Background: While pectoralis major (PM) tears are rare injuries in National Football League (NFL) athletes (previous study reported only 10 PM ruptures between 2000 and 2010), the incidence of these injuries has increased over the past decade. The impact these injuries have on a player’s performance after return has not been measured. Purpose/Hypothesis: To identify player characteristics that may predispose to PM tears and to determine the impact of this injury on return to play and performance. We hypothesized that there would be no difference in performance between the year before and after their injury. Study Design: Descriptive epidemiology study. Methods: NFL players who experienced PM tears between the years 2010 and 2018 were identified using publicly available reports. Several individual player characteristics were identified and recorded, and the return-to-play rates after injury were determined for each position. The pre- and postinjury Pro Football Focus grades of players who met inclusion criteria were compared. A paired t test analysis of the change in player performance was used for analysis. Results: In this study, 63 ruptures were identified between 2010 and 2018. Linebackers had the highest incidence of PM tear compared with any other position. Of all injuries, 79.3% were sustained by defensive players. The majority of PM tears occurred during games. Only 6.9% of players who sustained the injury were suspended for performance-enhancing drug use during their professional career. A total of 85.7% of players returned to play in the NFL after injury. Among those who returned to play there were no significant changes in player performance from pre- to post-injury. Conclusion: NFL players demonstrated 85.7% return-to-play rates and no significant drop-off in performance after PM ruptures. During the time period studied, there was an increase in incidence of PM ruptures compared with the previous decade. Further investigation is needed to determine potential causes for the increased incidence of PM ruptures in NFL players.

The Impact

A number of studies suggest a link between musical training and both specific and general cognitive abilities, but despite some positive results, there is disagreement about which abilities are improved. This study aims to investigate the effects of a music education program both on a domain-specific competence (meta-musical awareness), and on general domain competences, that is, cognitive abilities (logical-mathematical) and symbolic-linguistic abilities (notational). Twenty 4- to 6-year-old children participated in the research, divided into two groups (experimental and control) and the measures were administered at two different times, before and after a 6-month music program (for the experimental group) and after a sports training program (for the control group). Children performed meta-musical awareness tasks, logical-mathematical tasks, and emergent-alphabetization tasks. Non-parametric statistics show that a music program significantly improves the development of notational skills and meta-musical awareness while not the development of logical-mathematical skills. These results show that a musical program increases children’s meta-musical awareness, and their ability to acquire the notational ability involved in the invented writing of words and numbers. On the contrary, it does not affect the development of logical skills. The results are discussed in terms of transfer of knowledge processes and of specific versus general domain effects of a musical program.

Background:Women’s National Basketball Association (WNBA) players have a greater incidence of lower extremity injury compared with male players, yet no data exist on functional outcomes after Achilles tendon rupture (ATR).Purpose:To evaluate the effect of Achilles tendon repair on game utilization, player performance, and career longevity in WNBA athletes.Study Design:Cohort study; Level of evidence, 3.Methods:WNBA players from 1997 to 2019 with a history of ATR (n = 12) were matched 1:2 to a healthy control group. Player characteristics, game utilization, and in-game performance data were collected for each athlete, from which the player efficiency rating (PER) was calculated. Statistical analysis was performed comparing postinjury data to preinjury baseline as well as cumulative career data. Changes at each time point relative to the preinjury baseline were also compared between groups.Results:Of the 12 players with ATR, 10 (83.3%) returned to play at the WNBA level at a mean (±SD) of 12.5 ± 3.3 months. Four players participated in only 1 WNBA season after injury. There were no differences in characteristics between the 10 players who returned to play after injury and the control group. After return to play, the WNBA players demonstrated a significant decrease in game utilization compared with preinjury, playing in 6.0 ± 6.9 fewer games, starting in 12.7 ± 15.4 fewer games, and playing 10.2 ± 9.1 fewer minutes per game ( P < .05 for all). After the index date of injury, the players with Achilles repair played 2.1 ± 1.2 more years in the WNBA, while control players played 5.35 ± 3.2 years ( P < .01) Additionally, the players with Achilles repair had a significant decrease in PER in the year after injury compared with preinjury (7.1 ± 5.3 vs 11.0 ± 4.4; P = .02). The reduction in game utilization and decrease in PER in these players was maintained when compared with the matched controls ( P < .05 for both).Conclusion:The majority of WNBA players who sustained ATR were able to return to sport after their injury; however, their career longevity was shorter than that of healthy controls. There was a significant decrease in game utilization and performance in the year after return to play compared with healthy controls.

Abstract Background Procalcitonin (PCT) is a biomarker that shows good sensitivity and specificity in identifying septic patients. Methods This study investigated the diagnostic accuracy of PCT in a community hospital setting and how it compared to that of lactic acid. It explored the impact on patient care before and after PCT implementation regarding costs and length of stay. Two comparative groups were analyzed using an exploratory descriptive case–control study with data from a 19-month period after PCT implementation and a retrospective quasi-experimental study using a control group of emergency department patients diagnosed with sepsis using data before PCT implementation. Results Post-procalcitonin implementation samples included 165 cases and pre-procalcitonin implementation sample included 69 cases. From the 165 sepsis cases who had positive blood cultures, PCT had a sensitivity of 89.7%. In comparison, lactic acid's sensitivity at the current cutoff of 18.02 mg/dL (2.0 mmol/L) was 64.9%. There was a 32% decrease in median cost before and after PCT implementation, even with the length of stay remaining at 5 days in both time periods. Conclusions There was a significant decrease after the implementation of PCT in cost of hospitalization compared to costs before implementation. This cost is highly correlated with length of stay; neither the hospital nor the intensive care unit length of stay showed a difference with before and after implementation. There was a positive correlation between lactic acid and PCT values. PCT values had a higher predictive usefulness than the lactic acid values.

The Impact

Stigma toward mental disorders is one of today's most pressing global issues. The Covid-19 pandemic has exacerbated the barriers to social inclusion faced by individuals with mental disorders. Concurrently, stigma reduction interventions, especially those aimed at university students, have been more difficult to implement given social distancing and campus closures. As a result, alternative delivery for programs contributing to stigma reduction is required, such as online implementation. This paper reports the results of a controlled study focused on an online multi-component program on reducing stigma toward mental illness that included project-based learning, clinical simulations with standardized patients and E-Contact with real patients. A total of 40 undergraduate students from the Universidad del Desarrollo in Santiago, Chile, participated in the study. They were randomly divided between an intervention and control group. The intervention group participated in the online multi-component program, while the control group participated in an online educational program on cardiovascular health. We assessed the impact of the program by using the validated Spanish-language versions of the Attribution Questionnaire AQ-27 and the Questionnaire on Student Attitudes toward Schizophrenia with both groups, before and after the intervention. In addition, an ad hoc Likert scale ranging from 0 to 5 was used with the intervention group in order to assess the learning strategies implemented. Following the intervention, the participants belonging to the intervention group displayed significantly lower levels of stereotypes, perception of dangerousness, and global score toward people with schizophrenia (p &lt; 0.001). In addition, participants presented lower levels of dangerousness-fear, avoidance, coercion, lack of solidarity, and global score (p &lt; 0.001). The control group displayed no statistically significant differences in the level of stigma before and after the evaluation, for all of the items assessed. Finally, the overall assessment of each of the components of the program was highly positive. In conclusion, the study shows that online programs can contribute to reducing stigma toward mental disorders. The program assessed in this study had a positive impact on all the dimensions of stigma and all of the components of the program itself were positively evaluated by the participants.
