Background Annually there are an estimated 4.5 million sports- and recreation-related injuries among children and young adults in the United States. The most common sports-related injuries are to the lower extremities, with two-thirds occurring among children and young adults (age range 5-24 years). The objective is to describe the epidemiology of lower leg injuries across 27 high school (HS) sports over a 3-year period. Methods The Datalys Center for Sports Injury Research and Prevention provided lower leg injury data for 27 sports in 147 high schools for 2011-2012 through 2013-2014 academic years from National Athletic Treatment, Injury and Outcomes Network (NATION) HS Surveillance Program. Results The overall rate of lower leg injuries over this 3-year period was 1.70 per 10 000 acute events (AEs) (95% CI, 1.59-1.82). In men, the highest number of lower leg injuries was in football (n=181), but indoor track had the highest rate of injury at 2.80 per 10 000 AEs (95% CI, 2.14-3.58). In women, the highest number of lower leg injuries and the highest rate of injury were in cross-country (n=76) at 3.85 per 10 000 AEs (95% CI, 3.03-4.81). The practice injury rate was 0.91 times the competition injury rate (95% CI, 0.78-1.07). Conclusion An improved understanding of the most common sports in which lower leg injuries are seen may help direct appropriate resource utilization. Our data would suggest efforts toward prevention of these overuse injuries, especially in football, track, and cross-country may have the greatest impact on the health of student athletes. Level of Evidence: Level IV, case series.

Now culture of manage safety, health and wellbeing in the mining industry needs a scientifically sound new approach to the training process for professionals at all levels. Insufficient qualification of employees and managers in occupational safety, health and wellbeing has a negative impact on the occupational injury rate, and the current occupational safety, health and wellbeing management system does not allow to instill in employees compliance with the requirements for their own safety. To improve the quality of employees training in safe work practices and to ensure their health, safety and wellbeing in processes, a new training process has been developed and implemented based on a video-based continuous learning system. The innovation will make it possible to manage the human factor by improving employees competence, increasing the efficiency of the system OSH management, taking prompt corrective action, reducing injury rates and retaining human resources.

Parkour consists of overcoming obstacles mostly in an urban landscape. Little is known regarding usual training habits and injury risks of traceurs, i.e., parkour practitioners. In this study, a 20-min survey have been fulfilled by a population of traceurs regarding training load, habits (type of warm up, physical conditioning, stretching), type of footwear, and number and type of ankle- and knee-injuries during their career. A total of 180 responses were analyzed (24.4 ± 5.9 years old, 21.7% female, 6.0 ± 3.9 years of experience). Participants reported to train 1 to 7 times per week for a mean duration of 2.2 h. 76% practiced stretching exercises. 75.6% practiced physical conditioning in addition to their parkour training (weightlifting, functional exercises). Injury rate was 1.7 per 1000 h of training, mostly ankle sprains and knee contusions. Number of injury and training load were positively correlated. The lack of physical conditioning was also a factor of injury. Knee injuries have been more frequent on participants wearing minimalist shoes. Although training appears well auto-organized and the injury rate quite low some pitfalls require attention, notably in training planning, warm-up, stretching and conditioning. Building training and coaching methods specific to parkour appears essential.

ABSTRACT Context: With 8 million annual participants in the United States, the epidemiology of sports-related injuries in high school athletics has garnered significant interest. The most recent studies examining overuse injury rates in high school sports reported data from 2012–2013 and therefore may not reflect current overuse injury rates in high school sports. Objective: To 1) to determine overuse time-loss (TL) and non-time-loss (NTL) injury rates among high school student athletes using NATION-SP data collected from 2014–2015 to 2018–2019 and 2) compare overuse injury rates based on student-athlete gender defined by sport, sport, and injury location. Design: Descriptive epidemiology study. Setting: Online injury surveillance from 211 high schools (345 individual years of high school data). Patients or Other Participants: Athletes participating in secondary school-sponsored boys' and girls' sports. Main Outcome Measures: Boys' and girls' overuse injury data from the National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) from the 2014–2015 to 2018–2019 school years were analyzed. Overuse injuries were identified using a combination of reported injury mechanism and diagnosis. TL injuries resulted in restriction from participation beyond the day of injury; a NTL injury did not result in restriction from participation beyond the day of injury or lost no time due to the injury. Injury counts, rates, and rate ratios (IRRs) were reported with 95% confidence intervals (CIs). Results: The overall overuse injury rate was 5.3/10,000 AEs (95%CI=5.1, 5.7), the NTL overuse injury rate was 3.4/10,000 AEs (95%CI=3.1, 3.6), and the TL overuse injury rate was 2.0/10,000 AEs (95%CI=1.8, 2.2). The overuse injury rate was greater in girls' sports compared to boys' sports (IRR=1.9; 95%CI=1.7, 2.1). The highest rates of overuse injury were reported in girls' cross-country (19.2/10,000 AEs; 95%CI=15.0, 24.2), girls' track and field (16.0/10,000 AEs; 95%CI=13.5, 18.8), and girls' field hockey (15.1/10,000 AEs; 95%CI=10.2, 21.6). Overuse injury rates were highest for the lower extremity compared to the upper extremity (IRR=5.7; 95%CI=4.9, 6.7) and for the lower extremity compared to the trunk and spine (IRR=8.9; 95%CI=7.3, 10.8). Conclusions: Awareness of overuse injury risk as well as prevention and intervention recommendations are necessary and should be specifically targeted towards cross-country, field hockey, and track and field athletes.

BACKGROUND: An ankle sprain is a common joint sprain in sports injury, which is closely related to its physiological position and anatomical characteristics, and may progress into chronic ankle instability after improper early treatment or premature exercise. OBJECTIVE: To analyze the tertiary rehabilitation effect of acute lateral ankle sprain caused by sports training. METHOD: Ninety-six athletes with acute lateral ankle sprain diagnosed from January 2019 to June 2020 were included and divided into the control group and the rehabilitation group using the random number table grouping method, with 48 cases in each group. The two groups received standardized treatment, and the rehabilitation group additionally received tertiary rehabilitation. The American Orthopedic Foot and Ankle Society (AOFAS ) scores, degree of ankle swelling, pain, and re-injury rate were compared between the two groups. RESULTS: The AOFAS scores of the two groups increased after treatment (P< 0.05). The degree of swelling in both groups after treatment was improved (P< 0.05). The Visual Analogue Scale (VAS) scores in both groups declined two weeks after treatment, with lower results observed in the rehabilitation group The two groups showed similar results of the follow-up visit (P< 0.05). CONCLUSION: Rehabilitation exercise on acute lateral ankle sprain effectively relieves ankle swelling and pain.

Background: Updated epidemiology studies examining sports-related concussions (SRCs) are critical in evaluating recent efforts aimed at reducing the incidence of SRCs in National Collegiate Athletic Association (NCAA) sports. Purpose: To describe the epidemiology of SRCs in 23 NCAA sports during the 2014/15-2018/19 academic years. Study Design: Descriptive epidemiology study. Methods: SRC and exposure data collected in the NCAA Injury Surveillance Program were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics by sport, event type (practices, competitions), injury mechanism (player contact, surface contact, equipment/apparatus contact), and injury history (new, recurrent). Injury rate ratios (IRRs) were used to examine differential injury rates, and injury proportion ratios (IPRs) were used to examine differential distributions. Results: A total of 3497 SRCs from 8,474,400 athlete-exposures (AEs) were reported during the study period (4.13 per 10,000 AEs); the competition-related SRC rate was higher than was the practice-related SRC rate (IRR, 4.12; 95% CI, 3.86-4.41). The highest SRC rates were observed in men’s ice hockey (7.35 per 10,000 AEs) and women’s soccer (7.15 per 10,000 AEs); rates in women’s soccer and volleyball increased during 2015/16-2018/19. Player contact was the most prevalently reported mechanism in men’s sports (77.0%), whereas equipment/apparatus contact was the most prevalently reported mechanism in women’s sports (39.2%). Sex-related differences were observed in soccer, basketball, softball/baseball, and swimming and diving. Most SRCs reported in men’s sports (84.3%) and women’s sports (81.1%) were reported as new injuries. Conclusion: Given the increasing SRC rates observed in women’s soccer and volleyball during the latter years of the study, these results indicate the need to direct further attention toward trajectories of SRC incidence in these sports. The prevalence of equipment/apparatus contact SRCs in women’s sports also suggests that SRC mechanisms in women’s sports warrant further investigation. As most SRCs during the study period were reported as new injuries, the prevalence of recurrent SRCs in men’s and women’s ice hockey is also noteworthy.

Abstract Studies show that 80-90% of losses are caused by human failure, both as individuals and organizations. Yet, only 3.4% of organizations have mature processes in place to actively identify, evaluate, and manage their risks. Safety culture, which has been introduced for more than two decades, has been considered as an effective approach to improve safety performance. Having a positive safety culture is now seen as a prerequisite for, and the basis for, good safety performance. Thus, good safety culture is considered a predictor of good safety performance. However, there are only a limited number of studies that examine the relationship between safety culture and safety performance. This study used a safety culture maturity framework and the level of injury as the variables measured at five sites of PT. X. Data for both variables were secondary data obtained directly from PT.X. The five sites were found to have a statistically significant difference between their injury rates but no statistically significant difference was observed between their safety culture maturity scores. The figure for the safety culture maturity in each site can be considered similar, considering that they have implemented a safety management system for more than two decades. At PT. X, the safety culture maturity alone cannot be considered to have a direct correlation with safety performance. There may be several other factors that contribute to safety performance. However, in sites with a high injury rate, a lower SCM score was identified in twelve elements of safety culture maturity when compared to the sites with low injury rates.

Abstract Background: More researches should be needed on injuries at ski resorts in Chongli, one of the sites of the 2022 Winter Olympics.Hypothesis: In Chinese ski resorts, injury accidents should be more frequent, and the injured body parts may be related to the protective clothingMethods: In this retrospective study, injuries at ski resorts in Chongli, China and Japan were analyzed to provide a reference for the ongoing injury prevention work at ski resorts. We collected data [see Additional file 1] on injuries at Wanlong and Fulong Ski Resort in Chongli during the 2017–2018 and 2018–2019 ski seasons. We referred to the ski injury report issued in February 2020 by the Japan Ski Safety Association [see Additional file 2]. The causes of and specific body parts involved in the injuries at both the Chinese and Japanese ski resorts were analyzed.Results: During the 2019–2020 ski season at the Japanese ski resorts, 0.93 injuries occurred per 10,000 skiers, and older skiers constituted a larger proportion of those injured, with 227 (8.6%) aged over 60 years. The knee joint was the most commonly injured body part among both Chinese and Japanese skiers, whereas shoulder joint injury was the most prevalent among snowboarders. Conclusion: The two Chongli ski resorts had a higher injury rate than the Japanese ski resorts. Medical treatment should focus more on older skiers, and helmet use requires urgent promotion

In Malaysia's manufacturing industry, workplace accidents and injuries are a big problem. This industry has made only minor progress in terms of reducing fatalities and significant injuries. The fatal injury rate decreased marginally; however, the previous year's severe injury rate stayed unchanged. (Department of Occupational Safety and Health (DOSH), 2021). As a result, manufacturing safety continues to be a severe issue in Malaysia. The organisational nature of industrial accidents has been highlighted in safety literature, and empirical study has focused on determining the organisational, managerial, and environmental elements that influence accident causation. The majority of prior works have emphasised the concept of safety culture (or safety climate). Scholars have recently begun to look into additional organisational elements, such as the impact of organisational environment, leadership style, and occupational stressors on industrial accidents. This study presents a conceptual framework to investigate the interaction between safety climate and safety behaviour in Malaysia's manufacturing sector, with the goal of developing more effective safety interventions to reduce accidents.

Abstract Long-term care is a challenging environment for quality improvement due to the high resident acuity, wide variation in resident needs, and wide variation in types and backgrounds of the large staff across three daily shifts. We report results from a learning collaborative undertaken to improve care quality and staff quality improvement skills in the VA CLCs through development of high functioning relationally coordinated teams operating in accord with person-centered care principles. The collaborative included 27 CLCs. Over 9 months leadership teams completed action assignments supported by 5 workshops and regular group coaching calls. Evaluation included fidelity monitoring (attendance, mid- and final progress reports), satisfaction questionnaires, and review of the VA quality measures (CLC Compare). Pre-post participant evaluations revealed a significant increase in positive responses to the question “to what extent do you think applying these new skills/knowledge will improve quality in your CLC?” and positive responses trending toward significance in ratings of abilities to apply new skills. Open-ended survey comments were positive and indicated change in understanding and practice: “utilizing the daily huddle to facilitate real time communication afforded the team a proactive approach to providing care and reducing acute exacerbations. We are able to avert, evaluate as a real time team and make it happen in the now not as a look back.”; “definitely unified front-line staff and CLC leadership.” Some changes were achieved in CLC Compare quality scores (e.g., falls with major injury rate had a 9.6 reduction (average rate = 3.39 pre, 3.07 post)).
