ABSTRACT Introduction: Taekwondo is one of the main events of the Olympic Games. It mainly uses hands and feet for fighting or confrontation and the competition is extremely fierce. Therefore, Taekwondo is more prone to muscle, bone, and joint sports injuries. Objective: To understand the characteristics of taekwondo sports injuries. Methods: Using the literature and questionnaire survey methods, mathematical statistics is used to investigate the sports injuries of young Taekwondo athletes. Results: Among 100 young Taekwondo athletes, 93individuals had different degrees of sports injuries, accounting for 93%, and 7had no sports injuries, accounting for only 7%. The total number of injuries was 160 or 1.6injuries per capita. Conclusions: Athletes should improve their ideological understanding and training level and pay attention to the timely treatment of acute injuries, which can effectively reduce sports injuries. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT Introduction: With the extensive and in-depth development of Taekwondo in China, more and more people participate in Taekwondo training. Due to the lack of experience of some coaches and the misunderstanding of scientific sports training by young athletes, injuries occur from time to time. This has a bad effect on Taekwond itself, and it can also damage the health of athletes. Objective: This article discusses joint injuries in Taekwondo and analyzes the characteristics of Taekwondo sports injuries and preventive methods. Methods: This article uses a questionnaire applied to young athletes to gain an understanding of the sports injuries situation. Results: The most common injury sites were feet and joints. The nature of the injuries is mostly soft tissue injury, ligament laceration, and muscle strain. The most serious injuries are kidney and perineal damage. Conclusion: Improving the level of training, strengthening medical supervision, and paying attention to the timely treatment of acute injuries are important ways to reduce the occurrence of trauma. Level of evidence II; Therapeutic studies - investigation of treatment results.

ObjectivesThis study will contribute to the systematic epidemiological description of morbidities among migrants, refugees and asylum seekers when crossing the Mediterranean Sea.SettingSince 2015, Médecins sans Frontières (MSF) has conducted search and rescue activities on the Mediterranean Sea to save lives, provide medical services, to witness and to speak out.ParticipantsBetween November 2016 and December 2019, MSF rescued 22 966 migrants, refugees and asylum seekers.Primary and secondary outcome measuresWe conducted retrospective data analysis of data collected between January 2016 and December 2019 as part of routine monitoring of the MSF’s healthcare services for migrants, refugees and asylum seekers on two search and rescue vessels.ResultsMSF conducted 12 438 outpatient consultations and 853 sexual and reproductive health consultations (24.9% of female population, 853/3420) and documented 287 consultations for sexual and gender-based violence (SGBV). The most frequently diagnosed health conditions among children aged 5 years or older and adults were skin conditions (30.6%, 5475/17 869), motion sickness (28.6%, 5116/17 869), headache (15.4%, 2 748/17 869) and acute injuries (5.7%, 1013/17 869). Of acute injuries, 44.7% were non-violence-related injuries (453/1013), 30.1% were fuel burns (297/1013) and 25.4% were violence-related injuries (257/1013).ConclusionThe limited testing and diagnostics capacity of the outpatient department, space limitations, stigma and the generally short length of stay of migrants, refugees and asylum seekers on the ships have likely led to an underestimation of morbidities, including mental health conditions and SGBV. The main diagnoses on board were directly related to journey on land and sea and stay in Libya. We conclude that this population may be relatively young and healthy but displays significant journey-related illnesses and includes migrants, refugees and asylum seekers who have suffered significant violence during their transit and need urgent access to essential services and protection in a place of safety on land.

Background. Acromioclavicular dislocation is a fairly common traumatic injury of the musculoskeletal system, and according to different authors varies from 2 to 26.1 % dislocations of other localizations, and is about 10 % of all acute injuries of the shoulder girdle, taking 3rd place after dislocations of shoulder and forearm. The social significance of this damage is determined by the occurrence mainly among young working-age men. The work was aimed to identify factors that cause unsatisfactory anatomical and functional results after surgical treatment of acromioclavicular dislocations. Materials and methods. This retrospective study (2015–2020) included 93 patients who had surgical intervention for acromioclavicular dislocation. Surgical stabilization of the acromial end of the clavicle was done by Hook Plate and by Weber technic. Results. The outcome of research shows that 49.5 % of cases had good results, 31.2 % — satisfactory, and 19.3 % — poor. There is a direct correlation between unsatisfying outcome and increased severity of the injury. The study found that 9.7 % of unsatisfying results were associated while using Weber’s technic in the Tossy II, while in Tossy III, it was 27.0 %. A similar correlation was found while using Hook Platе, in the case of Tossy II, unsatisfying results were in 15.8 % of cases and Tossy III — 29.4 %. Conclusions. The reason for the unsatisfying results of the surgical acromioclavicular dislocations treatment is the severity of damage and the absence of an algorithm for diagnosis and management of this injury. In Tossy III dislocations, the use of stabilization methods as Weber’s technic, Hook Plate, or suturing damaged acromioclavicular ligaments did not demonstrate satisfying effectiveness.

IL-22 plays a crucial role in promoting inflammation, antimicrobial immunity and tissue repair at barrier surfaces. The role of IL-22 in colitis is still controversial: while IL-22 has a protective effect on gut epithelium in acute injuries, it also enhances colitis in a context-dependent manner. Here, we summarize the Yin and Yang of IL-22 in colitis. Particularly, we emphasize the role of innate lymphoid cells (ILCs) in IL-22 production and regulation. A previously underappreciated transcription factor, Musculin (MSC), has been recently identified to be expressed in not only Th17 cells, but also RORγt+/Id2+ IL-22-producing group 3 ILCs in the gut of naïve mice. We hypothesize that the co-expression and interaction of MSC with the key transcription repressor Id2 in developing lymphoid cells (e.g., in LTi cells) and ILC precursors might fine tune the developmental programs or regulate the plasticity of adaptive Th subset and innate ILCs. The much-elevated expression of IL-22 in MSC-/- ILC3s suggests that MSC may function as: 1) a transcription suppressor for cytokines, particularly for IL-22, and/or 2) a gatekeeper for specific lineages of Th cells and innate ILCs as well. Amelioration of colitis symptoms in MSC-/- mice by IL-22-blocking agent IL-22BP-Fc suggests a counterintuitive pathogenic role of IL-22 in the absence of MSC as a checkpoint. The theory that exuberant production of IL-22 under pathological conditions (e.g., in human inflammatory bowel disease, IBD) may cause epithelial inflammation due to endoplasmic reticulum (ER) stress response is worth further investigation. Rheostatic regulation of IL-22 may be of therapeutic value to restore homeostatic balance and promote intestinal health in human colitis.

This study examined the impact of high adherence to a neuromuscular training (NMT) warm-up on the risk of lower extremity (LE) injuries in children’s soccer. Twenty U11–U14 youth clubs (n = 92 teams, 1409 players) were randomized into intervention (n = 44 teams) and control (n = 48 teams) groups. The intervention group was advised to perform an NMT warm-up 2 to 3 times a week for 20 weeks. Team adherence, injuries, and exposure were registered throughout the follow-up. Primary outcomes were the incidence of soccer-related acute LE injuries and the prevalence of overuse LE injuries. Intervention teams conducted mean 1.7 (SD 1.0) NMT warm-ups weekly through follow-up. The seasonal trend for adherence declined significantly by −1.9% (95% CI −0.8% to −3.1%) a week. There was no difference in the incidence of acute injuries nor the prevalence of overuse LE injuries in high team adherence group (n = 17 teams) compared to controls. However, the risk for acute noncontact LE injuries was 31% lower in the high team adherence group compared to controls (IRR 0.69, 95% CI 0.49 to 0.97). In an efficacy analysis (n = 7 teams), there was a significant reduction of 47% in the rate of noncontact LE injuries (IRR 0.53, 95% CI 0.29 to 0.97). In conclusion, teams conducted NMT warm-up sessions regularly, but with a declining trend. A greater protective effect was seen in teams with the highest adherence to the NMT warm-up.

Surfing has rapidly grown in popularity as the sport made its debut at the Tokyo 2020 Olympic Games. Surfing injuries are becoming more relevant with the globalisation and increasing risks of the sport, but despite this, little is known about surfing injuries or prevention strategies in either the competitive or recreational surfer. Prior research demonstrates that surfers are injured at a frequency of 0.74–1.79 injuries per 1000 hours of surfing. We reviewed the literature for the incidence, anatomical distribution, type and underlying mechanism of acute and overuse injuries, and discuss current preventative measures. This review finds that skin injuries represent the highest proportion of total injuries. Acute injuries most frequently affect the head, neck and face, followed by the lower limbs. Being struck by one’s own board is the most common mechanism of injury. Non-contact acute ligament injuries have increased as surfing manoeuvres have become more acrobatic and overuse musculoskeletal injuries are highly correlated with paddling. However, there is a paucity of research for surfing injuries, and studies on overuse musculoskeletal injuries and prevention are disproportionally under-represented. Most of the prior studies are limited by small sample sizes, poor data collection methodology and geographical constraints. Further research is needed to establish preventative measures for both acute and overuse surfing injuries and to ensure the increasing popularity of surfing is met with an improved understanding of sport risks and safety. Specifically, we recommend research be prioritised regarding the efficacy of training programmes to prevent surfing-related overuse musculoskeletal injuries.

The circadian gene expression rhythmicity drives diurnal oscillations of physiological processes that may determine the injury response. While outcomes of various acute injuries are affected by the time of day at which the original insult occurred, such influences on recovery after spinal cord injury (SCI) are unknown. We report that mice receiving moderate, T9 contusive SCI at ZT0 (zeitgeber time 0, time of lights on) and ZT12 (time of lights off) showed similar hindlimb function recovery in the Basso mouse scale (BMS) over a 6 week post-injury period. In an independent study, no significant differences in BMS were observed after SCI at ZT18 vs. ZT6. However, the ladder walking test revealed modestly improved performance for ZT18 vs. ZT6 mice at week 6 after injury. Consistent with those minor effects on functional recovery, terminal histological analysis revealed no significant differences in white matter sparing at the injury epicenter. Likewise, blood-spinal cord barrier disruption and neuroinflammation appeared similar when analyzed at 1 week post injury at ZT6 or ZT18. Therefore, locomotor recovery after thoracic contusive SCI is not substantively modulated by the time of day at which the neurotrauma occurred.

Abstract Background Gymnastics requires a high level of physical ability and technical skill which utilises short sets of athleticism and artistry to perform complex and intense movements which can overload musculoskeletal tissues and result in acute injuries which can develop into chronic injuries. The aim of this systematic literature review was to investigate which screening tools predict injury in gymnasts and encompasses all genres, levels and ages. Methods An electronic search of seven databases from their inception until March 2021 was conducted. The databases were the Allied and Complementary Medicine Database, CINAHL, eBook Collection (EBSCOhost), MEDLINE, Cochrane Database of Systematic Reviews, SPORTDiscus and PEDro (the Physiotherapy Evidence Base). A combination of the following search terms was used: (1) Gymnastics AND injury AND Screening, (2) Screening AND Gymnastics and (3) Musculoskeletal AND Screening AND Gymnastics. These terms were searched in all text, abstract, title and subject terms. Studies were assessed using a 20-point scoring tool. Results The mean methodological quality score was 13.1 points (range 10–17 points). Range of motion, anthropometric and postural measurements, hypermobility, clinical diagnostic tests, movement screening tools, muscle strength, power and endurance were reported in the included studies. Some evidence existed for screening measurement of height and mass as taller and heavier gymnasts might be more susceptible to injury; however, the different methodologies utilised and lack of acknowledgment of confounding variables limit the clinical relevance of these findings. Conclusions Height and mass should be recorded during the screening process. A lack of heterogeneity in study methodology prevented a meta-analysis. Studies were limited by a lack of prospective injury design, poor injury definition, self-reporting of injury and only 2 studies reported reliability of screening tools. Further research is required to determine the role of injury screening in gymnastics. Registration: The review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) with the registration number CRD42020218339.
