RESUMEN
Rationale: Pulmonary complications contribute significantly to nonrelapse mortality following hematopoietic stem cell transplantation (HCT). Identifying patients at high risk can help enroll such patients into clinical studies to better understand, prevent, and treat posttransplantation respiratory failure syndromes. Objectives: To develop and validate a prediction model to identify those at increased risk of acute respiratory failure after HCT. Methods: Patients underwent HCT between January 1, 2019, and December 31, 2021, at one of three institutions. Those treated in Rochester, MN, formed the derivation cohort, and those treated in Scottsdale, AZ, or Jacksonville, FL, formed the validation cohort. The primary outcome was the development of acute respiratory distress syndrome (ARDS), with secondary outcomes including the need for invasive mechanical ventilation (IMV) and/or noninvasive ventilation (NIV). Predictors were based on prior case-control studies. Measurements and Main Results: Of 2,450 patients undergoing stem cell transplantation, there were 1,718 hospitalizations (888 patients) in the training cohort and 1,005 hospitalizations (470 patients) in the test cohort. A 22-point model was developed, with 11 points from prehospital predictors and 11 points from posttransplantation or early (<24-h) in-hospital predictors. The model performed well in predicting ARDS (C-statistic, 0.905; 95% confidence interval [CI], 0.870-0.941) and the need for IMV and/or NIV (C-statistic, 0.863; 95% CI, 0.828-0.898). The test cohort differed markedly in demographic, medical, and hematologic characteristics. The model also performed well in this setting in predicting ARDS (C-statistic, 0.841; 95% CI, 0.782-0.900) and the need for IMV and/or NIV (C-statistic, 0.872; 95% CI, 0.831-0.914). Conclusions: A novel prediction model incorporating data elements from the pretransplantation, posttransplantation, and early in-hospital domains can reliably predict the development of post-HCT acute respiratory failure.

OBJECTIVE: To assess pre and postself-reported counseling outcomes for Safer: Storing Firearms Prevents Harm, an American Academy of Pediatrics universal firearm safe storage counseling training for pediatric clinicians providing health maintenance in outpatient settings. STUDY DESIGN: Safer was developed by a national multidisciplinary committee of firearm injury prevention experts with input from firearm-owning families and launched in June 2021. Pediatric clinicians completed baseline and 1-month posttraining surveys after signing up for the Pedialink course from February through June 2022. Primary outcomes included self-reported measures of counseling self-efficacy and frequency. Wilcoxon matched-pairs signed-rank tests compared outcome distributions at baseline and follow-up. Two adjusted, multilevel mixed-effects regression models were conducted. RESULTS: Of 230 clinicians who completed baseline surveys, 146 (64%) completed 1-month postsurveys. Regional representation included Southeast = 67 (46%), Northeast = 24 (16%), Midwest = 21 (14%), Pacific = 15 (10%), Southwest = 11 (8%), and Rocky Mountain = 8 (5%). At follow-up, there was significant improvement in both the distribution of self-efficacy (median [first Quartile-third Quartile = 50 [20-70] at baseline and 80 [60-85] at follow-up; P < .001) and self-reported counseling frequency (median [first Quartile-third Quartile] = 10 [0-50] at baseline and 50 [10-80] at follow-up; P < .001). Adjusted regression model results suggested that self-efficacy significantly improved from baseline to follow-up (time coefficient 25.3; 95% CI = [21.0, 29.5]; P < .001) as did counseling frequency (time coefficient 13.6; 95% CI = [9.2, 18.0]; P < .001). CONCLUSIONS: Significant improvement in self-reported counseling self-efficacy and frequency was demonstrated 1 month following Safer training.

INTRODUCTION: Children spend most of their time at school and participate in many activities that have the potential for causing injury. This study aims to describe the nationwide epidemiology of pediatric trauma sustained in school settings in the United States. METHODS: In the 3-y analysis of 2017-2019 American College of Surgeons-Trauma Quality Program, all pediatric trauma patients (≤18 y) injured in a school setting were included and stratified based on place of injury, into elementary, middle, and high school (HS) groups. Descriptive statistics and multivariable logistic regression analysis were performed to identify the independent predictors of intentional injuries. RESULTS: 23,215 pediatric patients were identified, of which 15,264 patients were injured at elementary (57.6%), middle (17.5%), and high (25%) schools. The mean age was 9.5 y, 66.9% were male, 63.9% were white, the median injury severity score was 2 [1-4], and 95.6% had a blunt injury. Elementary school students were more likely to sustain falls (85%) and humerus fractures (43%) whereas HS students were more likely to be injured by assaults (17%). Overall, 7% of the students sustained intentional injuries. On multivariable logistic regression, male gender (odds ratio [OR] 1.54), Black race (OR 2.94), American Indian race (OR 1.88), Hispanic ethnicity (OR 1.77), positive drug screen (OR 4.9), middle (OR 5.2), and HSs (OR 10.6) were identified as independent predictors of intentional injury (all P < 0.01). CONCLUSIONS: Injury patterns vary across elementary, middle, and HSs. Racial factors appear to influence intentional injuries along with substance abuse. Further studies to understand these risk factors and efforts to reduce school injuries are warranted to provide a safe learning environment for children.

OBJECTIVE: To better understand processes of mental health crisis line utilization by examining associations between reasons for contacting a crisis line with the initiation of emergency dispatches (i.e., activation of 911 or local emergency services) in a national sample. METHODS: Contacts (i.e., calls, texts, email, and chats) to the Veterans Crisis Line (VCL) across 2017-2020 were used to examine associations among stated reasons for the contact and the use of an emergency dispatch. Hierarchical logistic regression models were used to determine the odds of an emergency dispatch by reason for the contact. RESULTS: Suicidal thoughts/crisis were present in 61.5% of contacts that ended in emergency dispatches and were associated with the largest adjusted odds of a dispatch, (Adjusted Odds Ratio [AOR] [95% CI] = 9.34 [9.21, 9.48]), followed by homicidal thoughts/crisis (AOR [95% CI] = 3.84 [3.73, 3.95]), and third-party concerns (AOR [95% CI] = 2.42 [2.37, 2.47]). Substance use/ addiction (AOR [95% CI] = 2.14 [2.10, 2.18]), abuse and violence (AOR [95% CI] = 1.89 [1.82, 1.96]), and physical health (AOR [95% CI] = 1.87 [1.84, 1.91]) were also associated with increased odds of a dispatch. CONCLUSIONS: Emergency dispatches are primarily used in response to imminent suicide risk but are also used in other potentially violent or lethal circumstances such as homicides, violence or abuse, and other crises. These findings highlight the role that crisis lines play in emergency service delivery, and the need to better understand how they are utilized under real world circumstances.

We aimed to explore perspectives of teenagers on their exposure to gun violence (GV), their knowledge and attitudes towards firearm injury prevention (FIP) efforts, and how to counsel them about FIP. Teens from two single-sex Bronx Catholic high schools participated in videoconferencing focus groups. Participants completed an online survey collecting demographic information and Likert-scale scoring of attitudes towards GV. Quantitative data was analyzed with descriptive statistics. Focus group discussions were recorded and transcribed. Using Dedoose, two investigators independently coded data and achieved consensus using content analysis. Six focus groups (3 from each school, n = 28 participants) were held from October-November 2020. A total of 27 participants completed the survey. Eighty-one percent of respondents agreed "Doctors should talk to teens about gun safety." During focus groups, participants reported personal, community, and entertainment media exposure to GV. GV elicited many emotions, including fear and frustration. Teens identified factors contributing to GV that should be addressed, including poverty, racism, and mental illness. Most had not received prior FIP education and desired more information from trusted adults. They preferred discussions over written materials and information given over time. Teens were open to doctors counseling on FIP during healthcare visits and suggested including screening questions on surveys, conversations during healthcare maintenance visits, and classroom talks by physicians. Bronx teens are exposed to and distressed by community GV. They desired more FIP education, including physician counseling during healthcare visits. Next steps are to create and test FIP guidance for adolescents.

OBJECTIVE: Unintentional injury is the leading cause of death to children worldwide, and playgrounds pose a significant risk of injury. Those aged 5 and 6 years are particularly vulnerable to playground injuries. Previous interventions have typically targeted environmental modifications or increased supervision to reduce playground injuries; however, minimal research has focused on implementing behavioral interventions that seek to change children's safety knowledge and risk-taking behaviors on the playground. The current randomized trial addressed these gaps in the literature and sought to increase preschool children's hazard awareness skills and knowledge of unsafe playground behaviors and decrease their intentions to engage in risk-taking behaviors on the playground. METHOD: A total of 77 children aged 5 and 6 years were tested at a laboratory on a university campus, using a parallel group design, with 38 randomized to the playground intervention group and 39 randomly assigned to a control group. The intervention was manualized and delivered to small groups of children (3-5) over several sessions. RESULTS: Statistical analyses revealed significant group differences. Intervention experience led to significant increases in hazard awareness skills and knowledge of unsafe playground behaviors, and significant decreases in children's risk-taking behavioral intentions, whereas those in the control group showed no significant changes in these scores. Attention scores for those in the intervention group highlighted that the program content was successful in maintaining children's attention and engagement, and memory scores indicated excellent retention of lesson content. CONCLUSION: The program shows promise in addressing the issue of unintentional playground injuries in young children.

BACKGROUND: Our goal was to summarize and contextualize the available literature on alpine ski racing injury epidemiology, injury etiology, injury prevention measures, injury prevention context, and implementation issues. MATERIALS AND METHODS: We searched four electronic databases using predetermined search terms. We included original studies that assessed injury, injury risk factors, and injury mechanisms, and assessed and reported the effect of an injury prevention measure in alpine ski racing. Two authors independently conducted title-abstract screening, and one performed the full-text review. For data synthesis and categorization, we used the Translating Research into the Injury Prevention Practice framework and a modified and adapted version of the Haddon matrix. RESULTS: Of the 157 included studies, most corresponded to injury epidemiology and etiology, whereas few studies encompassed injury prevention measure development, implementation and evaluation. Preventive interventions targeting equipment, rules and regulations, course design and snow preparation were the most prevalent in the literature. Furthermore, various contextual factors in the current literature have been found, including gender, competition level, countries and federations, and time periods within a season. CONCLUSIONS: We provided an in-depth and comprehensive overview of the current state-of-the-art in the alpine ski racing context. We know a lot about little and little about a lot across all the areas associated with injury prevention in such context. The limitations in the literature yield a road map for designing future injury prevention studies to address the key gaps identified. A more comprehensive context-driven approach throughout all stages of injury prevention would benefit the ultimate implementation of effective preventive strategies.

OBJECTIVE: This process evaluation aimed to gain insight into the implementation of the VolleyVeilig Youth program by Dutch volleyball clubs within the context of an effectiveness trial. METHODS: We applied the UK Medical Research Council framework for process evaluations and assessed the context, implementation and mechanisms of impact. Trainers participating in the effectiveness trial were asked to complete a questionnaire at the end of the study. A subsample of the trainers based on the self-reported adherence score was invited to participate in an interview accordingly. We used a thematic analysis to present the data. RESULTS: Thirty-one trainers (100%) completed the questionnaire, and seven agreed to participate in an interview. Although adherence gradually decreased over the volleyball season, most trainers reported partially adhere with the program until the end of the study. The main themes included factors associated with the (1) VolleyVeilig Youth program, (2) trainer, (3) players, and (4) volleyball club. CONCLUSION: Although (partial) adherence to the VolleyVeilig Youth program was high in this study, implementation strategies must be developed to target the barriers reported by the trainers before the program can be successfully implemented nationwide in the Netherlands.

Through a national cross-sectional survey, the present study investigated the use and content of injury prevention training (IPT), and associated attitudes and beliefs, involving stakeholders in Danish girls' and women's elite football (U14, U16, U18, and Danish Women's League teams). A total of 168 stakeholders (coaches, physical performance coaches, physiotherapists, medical doctors, and club management) from 18 Danish elite clubs were invited to participate. Of these, 158 were eligible to participate, and 110 participants (69.6% response rate) provided 191 valid survey responses, as some provided more than one response due to multiple affiliations within the same club. The use of IPT ranged from 91.1% to 100% across team levels, with approximately 50% reporting up to 1-2 h/week. Interestingly, only 52.9%-72.7% of the responses indicated use of an evidence-based IPT program, with lowest adoption at the U14 and Danish Women's League teams. The FIFA 11+ was the most used evidence-based IPT program. The majority of the participants (>72%) had positive perceptions regarding IPT impact on injury reduction. These findings indicate that, while IPT is broadly used across Danish girls' and women's elite football teams, the implementation of evidence-based IPT programs varies, with lower adoption of these programs among the youngest and senior elite teams. Hence, there is a need to enhance integration of IPT programs proven effective in girls' and women's elite football. Notably, stakeholders expressed positive perceptions regarding the impact of IPT on injury reduction, which provides valuable support for future efforts to strengthen IPT in football practice.

Long-track and short-track ice speed skating are integral to the Winter Olympics. The state of evidence-based injury prevention in these sports is unclear. Our goals were to summarize the current scientific knowledge, to determine the state of research, and to highlight future research areas for injury prevention in ice speed skating. We conducted a scoping review, searching all injury and injury prevention studies in competitive ice speed skaters. The six-stage Translating Research into Injury Prevention Practice (TRIPP) framework summarized the findings. The systematic search yielded 1109 citations. Nineteen studies were included, and additional searches yielded another 13 studies, but few had high-quality design. TRIPP stage 1 studies (n = 24) found competition injury rates from 2% to 18% of participants with various injury locations and types. Seasonal prevalence of physical complaints was up to 84% (for back pain) in long- and short-track. Ten studies covered information on TRIPP stage 2, with two small etiological studies linking injuries to functional strength deficits (short-track) and training load (long-track). Questionnaire studies identified various perceived risk factors for injuries but lacked further scientific evidence. Most TRIPP stage 3 studies (five out of eight) focused on developing protective measures, while two studies found short-track helmets performed poorly compared to helmets used in other sports. No study evaluated the efficacy, the intervention context, or the effectiveness (TRIPP stages 4-6) of the measures. Scientific knowledge on injury prevention in ice speed skating is limited. Future research should prioritize high-quality studies on injury epidemiology and etiology in the sports.

OBJECTIVES: Describe head acceleration events (HAEs) experienced by professional male rugby union players during tackle, ball-carry, and ruck events using instrumented mouthguards (iMGs). DESIGN: Prospective observational cohort. METHODS: Players competing in the 2023 Currie Cup (141 players) and Super Rugby (66 players) seasons wore iMGs. The iMG-recorded peak linear acceleration (PLA) and peak angular acceleration (PAA) were used as in vivo HAE approximations and linked to contact-event data captured using video analysis. Using the maximum PLA and PAA per contact event (HAEmax), ordinal mixed-effects regression models estimated the probabilities of HAEmax magnitude ranges occurring, while accounting for the multilevel data structure. RESULTS: As HAEmax magnitude increased the probability of occurrence decreased. The probability of a HAEmax ≥15g was 0.461 (0.435-0.488) (approximately 1 in every 2) and ≥45g was 0.031 (0.025-0.037) (1 in every 32) during ball carries. The probability of a HAEmax >15g was 0.381 (0.360-0.404) (1 in every 3) and >45g 0.019 (0.015-0.023) (1 in every 53) during tackles. The probability of higher magnitude HAEmax occurring was greatest during ball carries, followed by tackles, defensive rucks and attacking rucks, with some ruck types having similar profiles to tackles and ball carries. No clear differences between positions were observed. CONCLUSION: Higher magnitude HAEmax were relatively infrequent in professional men's rugby union players. Contact events appear different, but no differences were found between positions. The occurrence of HAEmax was associated with roles players performed within contact events, not their actual playing position. Defending rucks may warrant greater consideration in injury prevention research.

BACKGROUND: Although road traffic injuries and deaths have decreased globally, there is substantial national and sub-national heterogeneity, particularly in low- and middle-income countries (LMICs). Ghana is one of few countries in Africa collecting comprehensive, spatially detailed data on motor vehicle collisions (MVCs). This data is a critical step towards improving roadway safety, as accurate and reliable information is essential for devising targeted countermeasures. METHODS: Here, we analyze 16 years of police-report data using emerging hot spot analysis in ArcGIS to identify hot spots with trends of increasing injury severity (a weighted composite measure of MVCs, minor injuries, severe injuries, and deaths), and counts of injuries, severe injuries, and deaths along major roads in urban and rural areas of Ghana. RESULTS: We find injury severity index sums and minor injury counts are significantly decreasing over time in Ghana while severe injury and death counts are not, indicating the latter should be the focus for road safety efforts. We identify new, consecutive, intensifying, and persistent hot spots on 2.65% of urban roads and 4.37% of rural roads. Hot spots are intensifying in terms of severity and frequency on major roads in rural areas. CONCLUSIONS: A few key road sections, particularly in rural areas, show elevated levels of road traffic injury severity, warranting targeted interventions. Our method for evaluating spatiotemporal trends in MVC, road traffic injuries, and deaths in a LMIC includes sufficient detail for replication and adaptation in other countries, which is useful for targeting countermeasures and tracking progress.

INTRODUCTION: Drowning is a public health problem in Türkiye, as in the rest of the world. This study aims to systematically review the literature on drowning in Türkiye with a focus on data sources, epidemiology, risk factors and prevention strategies. METHODS: Literature searches were conducted using PubMed, SPORTSDiscus, Scopus, Web of Science, Turk MEDLINE, Google Scholar and Google Akademik (Turkish language). Studies (limited to original research written in English and Turkish) reporting drowning (unintentional and intentional; fatal and non-fatal) of residents and tourists in Türkiye were independently dual screened at the title and abstract and full text stages. Study quality was assessed using JBI checklists and evidence level assessed based on study design. RESULTS: From a total of 917 studies, 49 met the inclusion criteria. Most (51%) focused on unintentional fatal drowning. Included studies were most commonly analytical cross-sectional studies (n = 23) and case series (n = 20) meaning the evidence level was low or very low for 48 (98%) studies. Fifteen studies examined drowning at the national level, while sub-national studies (n = 30) focused on urban areas across three provinces: Antalya (n = 6), Istanbul (n = 6), Izmir (n = 4). There was little consensus on risk factors beyond male drowning risk, and no data reported on implemented or evaluated drowning prevention interventions. DISCUSSION: There is a need for more national-level studies to identify the causes of drowning and to guide intervention implementation and evaluation to inform policy makers and donors. Currently official data is limited in its detail, providing age and gender data only, hampering efforts to identify, and thus address, causal factors for drowning. PRACTICAL APPLICATIONS: There is currently very little evidence to inform investment in effective drowning prevention interventions in Türkiye. To improve this, data collection systems on drowning in Türkiye need to be strengthened via the development a national drowning registry. TRIAL REGISTRATION: #CRD42022382615.

PURPOSE: This study utilized demographic and intrapersonal variables to identify individuals who may have falsely denied firearm ownership and determined if individuals can be divided into meaningful subgroups. METHODS: Participants were United States residents (N = 3500) recruited from January to June 2020. matched to the 2010 census data for age, race, sex, income, and education level. A Zero-Inflated Negative Binomial (ZINB) regression was utilized to determine potential underreporting of firearm ownership, and a latent class analysis was utilized to determine unique subgroups of those who were identified as underreporting firearm ownership in the ZINB. RESULTS: Participants (N = 1306) were identified as underreporting firearm ownership (excess zeros) based on a model that included demographic and intrapersonal variables. A latent class analysis indicated that among excess zeros, three unique subgroups exist. CONCLUSIONS: Determining who may be underreporting firearm ownership will allow for a more comprehensive understanding of firearm ownership in the US and more targeted safe storage messages that may reach those who own firearms and are at risk for firearm-related injury and death.

BACKGROUND: Coronavirus disease 2019 disrupted the delivery of public maternal and child health services to caregivers of preschool children, leading to decreased opportunities for injury prevention education. We aim to 1) explore the timing, content, and methods of providing injury prevention information desired by pregnant women and mothers and 2) identify mothers who experienced difficulty in obtaining injury prevention information owing to reduced maternal and child health services. METHODS: From March 24 to 29, 2022, we conducted a population-based cross-sectional study and web-based survey. Of the registered monitors of the internet research company Rakuten Insight, 675 mothers raising their first child aged 0-2 during the COVID-19 period (February 2020 to March 2022) were included in the analysis. RESULTS: Over half of the mothers wanted injury prevention information throughout their pregnancy. They preferred receiving information through traditional face-to-face services provided by local governments, such as antenatal classes or checkups. However, 34.1% of mothers said they did not obtain the information they needed; this was particularly true of unemployed mothers, had children aged 0-1, and had children with illnesses requiring hospital visits. CONCLUSIONS: Mothers who could not obtain injury prevention information were originally disadvantaged mothers concerning access to information. The decrease in maternal and child health services may have widened this information gap. These findings can inform recommendations for caregivers, particularly those susceptible to information gaps during emergencies, and offer insights into future injury prevention education strategies.

BACKGROUND: Suicide is a serious public health problem in the United States, but limited evidence is available investigating fatal suicides at work. There is a substantial need to characterize workplace suicides to inform suicide prevention interventions and target high-risk settings. This study aims to examine workplace suicide rates in North Carolina (NC) by worker characteristics, means of suicide used, and industry between 1992 and 2017. METHODS: Fatal workplace suicides were identified from records of the NC Office of the Chief Medical Examiner system and the NC death certificate. Sex, age, race, ethnicity, class of worker, manner of death, and industry were abstracted. Crude and age-standardized homicide rates were calculated as the number of suicides that occurred at work divided by an estimate of worker-years (w-y). Rate ratios and 95% confidence intervals (CIs) were calculated, and trends over calendar time for fatal workplace suicides were examined overall and by industry. RESULTS: 81 suicides over 109,464,430 w-y were observed. Increased rates were observed in workers who were male, self-employed, and 65+ years old. Firearms were the most common means of death (63%) followed by hanging (16%). Gas service station workers experienced the highest fatal occupational suicide rate, 11.5 times (95% CI: 3.62-36.33) the overall fatal workplace suicide rate, followed by Justice, Public Order, and Safety workers at 3.23 times the overall rate (95% CI: 1.31-7.97). CONCLUSION: Our findings identify industries and worker demographics that were vulnerable to workplace suicides. Targeted and tailored mitigation strategies for vulnerable industries and workers are recommended.

BACKGROUND: Construction workers have the second highest suicide death rate; despite this, there is limited literature examining suicides in the industry, which is necessary to identify those at higher risk of death by suicide. The objective of this study was to examine the characteristics of those who died by suicide in construction to address this knowledge gap. METHODS: Data from the National Center for Health Statistics National Vital Statistics System 2021 public use Mortality Multiple Cause-of-Death file were used to identify deaths by suicide, while denominator data for rates come from the 2021 Current Population Survey. RESULTS: In 2021, construction workers were disproportionately affected by suicide deaths. Almost a fifth (17.9%) of deaths by suicide with a reported industry code were in construction, despite construction workers accounting for only 7.4% of the workforce. Male construction workers accounted for a majority (97.8%) of suicide deaths. The highest percent of deaths by suicide were among individuals who were white, non-Hispanic, completed high school or equivalent, and single, across construction and all industries for males and females. DISCUSSION AND CONCLUSIONS: Male and female construction workers had the highest rates of suicide across all characteristics when compared to all industries. Our findings support the need for ongoing prevention efforts within the industry. Future research is needed to understand suicide risk among certain characteristics and occupations. In addition, the work environment or other work-related factors should be studied to understand how the unique nature of the construction industry may be associated with higher suicide rates.
RESUMEN
BACKGROUND: Despite the importance of enhancing exercise, exercising can cause injuries that lead to disability and increase the load on the medical sector. This study aimed to estimate the prevalence of exercise-related injuries among gym members in the Kingdom of Saudi Arabia (KSA) and evaluate the more common types of such injuries. It also investigated the association between injury prevalence and the factors selected. METHODS: A cross-sectional study with a self-reported survey was conducted targeting members of Fitness Time gyms across the KSA. The survey consisted of three parts: part one concerns participant demographic data and part two contains four questions regarding the participants' training experience. Part three contains ten questions targeting those with a history of injury. Descriptive statistical analysis was performed using frequencies and percentages for categorical variables. Crosstabs and chi-squared tests were used to assess the prevalence of exercise-related injuries when appropriate. Binary logistic regression was employed to investigate the association between injury prevalence and the potential associated factors. Odds ratios and their 95% confidence intervals were calculated and the threshold for statistical significance was set at p ≤ 0.05. RESULTS: A total of 713 subjects participated in the study. The mean age was 36.5 ± 11.2 years and (n = 422, 59.2%) of the participants were female. The study found a prevalence of injury among gym members of about (n = 404, ~57%). The most commonly reported types of injuries were muscle strain (n = 126, 37%) and bruising (n = 45, 13%). The most prevalent anatomical location of injury was the knee (n = 287, 84.3%), followed by the shoulder (n = 283, 83.3%), and the least common was the head/neck (n = 7, 2.1%). The present study suggests some factors associated with exercise-related injury. A significant statistical association (p < 0.5) was found between injury prevalence and age, gender, educational level, period of training, and presence of a trainer. However, no association was detected between injury prevalence and Body Mass Index (BMI), place of residence, or source of advice. CONCLUSION: Over half of the participants of this study reported at least one exercise-related injury. This study identifies factors associated with injury prevalence related to exercise among gym participants. Promoting safety and minimizing the incidence of injuries are crucial.

BACKGROUND: This study investigated the effects of changes in motor skills from an educational video program on the kinematic and kinetic variables of the lower extremity joints and knee ligament load. METHODS: Twenty male participants (age: 22.2 ± 2.60 y; height: 1.70 ± 6.2 m; weight: 65.4 ± 7.01 kg; BMI: 23.32 ± 2.49 [Formula: see text]) were instructed to run at 4.5 ± 0.2 m/s from a 5 m distance posterior to the force plate, land their foot on the force plate, and perform the cutting maneuver on the left. The educational video program for cutting maneuvers consisted of preparatory posture, foot landing orientation, gaze and trunk directions, soft landing, and eversion angle. The measured variables were the angle, angular velocity of lower extremity joints, ground reaction force (GRF), moment, and anterior cruciate ligament (ACL) and medial collateral ligament (MCL) forces through musculoskeletal modeling. RESULTS: After the video feedback, the hip joint angles increased in flexion, abduction, and external rotation (p < 0.05), and the angular velocity increased in extension (p < 0.05). The ankle joint angles increased in dorsiflexion (p < 0.05), and the angular velocity decreased in dorsiflexion (p < 0.05) but increased in abduction (p < 0.05). The GRF increased in the anterior-posterior and medial-lateral directions and decreased vertically (p < 0.05). The hip joint moments decreased in extension and external rotation (p < 0.05) but increased in adduction (p < 0.05). The knee joint moments were decreased in extension, adduction, and external rotation (p < 0.05). The abduction moment of the ankle joint decreased (p < 0.001). There were differences in the support zone corresponding to 64â87% of the hip frontal moment (p < 0.001) and 32â100% of the hip horizontal moment (p < 0.001) and differences corresponding to 32â100% of the knee frontal moment and 21â100% of the knee horizontal moment (p < 0.001). The GRF varied in the support zone at 44â95% in the medial-lateral direction and at 17â43% and 73â100% in the vertical direction (p < 0.001). CONCLUSIONS: Injury prevention feedback reduced the load on the lower extremity joints during cutting maneuvers, which reduced the knee ligament load, mainly on the MCL.

BACKGROUND: To identify mechanisms and patterns of anterior cruciate ligament (ACL) injury in adult women's professional football by means of video match analysis. METHODS: ACL match injuries sustained in Germany's first women's league during the 2016-2017 to 2022-2023 seasons were prospectively analysed by three expert raters using a standardised observation form. Epidemiological and injury data, as well as the medical history of ACL tears, were obtained from media reports and the statutory accident insurance for professional athletes. RESULTS: Thirty-seven ACL injuries sustained in official football matches were included in the video analysis, of which 24 (65%) had associated knee injuries, mainly meniscus and collateral ligament injuries. According to the categorised contact mechanisms, 17 (46%) were non-contact injuries, 14 indirect contact injuries (38%) and six direct contact injuries (16%). Of the 17 non-contact injuries, seven (41%) occurred during the first 15 min of the match. Contact mechanisms did not differ between primary and secondary ACL injuries to the same or the contralateral side. Most injuries (80%) of field players occurred during horizontal movements such as sprinting (n=9, 26%), change-of-direction manoeuvres (n=7, 19%), stopping (n=5, 14%) and lunging (n=5, 14%). Four distinct repetitive patterns of ACL match injuries were identified: (1) non-contact 'pressing ACL injury' (n=9), (2) indirect contact 'parallel sprinting and tackling ACL injury' (n=7), (3) direct contact 'knee-to-knee ACL injury' (n=6) and (4) non-contact 'landing ACL injury' (n=4). CONCLUSION: Most of the identified patterns of ACL injuries in women's professional football have great potential for prevention.
