Abstract Purpose To study distractive muscle injuries applying US and MRI specific classifications and to find if any correlation exists between the results and the return to sport (RTS) time. The second purpose is to evaluate which classification has the best prognostic value and if the lesions extension correlates with the RTS time. Methods A total of 26 male, professional soccer players (age 21.3 ± 5.6), diagnosed with traumatic muscle injury of the lower limbs, received ultrasound and MRI evaluation within 2 days from the trauma. Concordance between US and MRI findings was investigated. The relationships between MRI and US based injury grading scales and RTS time were evaluated. Correlation between injuries’ longitudinal extension and RTS time was also investigated. Results The correlation between US and MRI measurements returned a Spearman value of rs = 0.61 (p = .001). Peetrons and Mueller-Wohlfahrt grading scales correlations with RTS time were r = 0.43 (p = .02) and r = 0.83 (p =  < .001). The lesion’s extension correlation with RTS time was r = 0.63 (p < .001). The correlation between the site of the lesion and its location with the RTS time were rs = 0.2 and rs = 0.25. Conclusions Both US and MRI can be used as prognostic indicators along with the Peetrons (US) and the Mueller-Wohlfahrt (MRI) classifications. MRI is more precise and generates more reproducible results. The lesion craniocaudal extension must be considered as a prognostic indicator, while the injury location inside the muscle or along its major axis has doubtful significance.

Comprehensive Classification

Muscle injuries are recognized to be among the most frequent injuries occurring in the sporting and athletic population, and they account for more than 30% of all injuries in professional soccer players. Despite their considerable frequency and impact, there is still a lack of uniformity in the categorization, description and grading of muscle injuries.Dozens of systems based on clinical signs, ultrasound imaging (US) appearance or magnetic resonance imaging (MRI) findings have been proposed over the years. Most of them are three-grade systems that take into account pain, ROM limitation, swelling and hematoma, hypoechoic or hyperintense areas on US or MRI, and muscle gap or tendon involvement; however, they still lack evidence-based prognostic value. Recently, new comprehensive classification systems have been proposed, with the aim of developing uniform muscle injury terminology and giving each severity grade prognostic value.The systems that combine detailed MRI and US features with the clinical presentation, such as the Munich Muscle Injury Classification, the ISMuLT classification, and the British Athletic Classification, if used extensively, could improve the diagnosis, prognosis and management of muscle injuries.

The Impact

Abstract Muscle injuries of the lower limbs are currently the most common sport-related injuries, the impact of which is particularly significant in elite athletes. MRI is the imaging modality of choice in assessing acute muscle injuries and radiologists play a key role in the current scenario of multidisciplinary health care teams involved in the care of elite athletes with muscle injuries. Despite the frequency and clinical relevance of muscle injuries, there is still a lack of uniformity in the description, diagnosis, and classification of lesions. The characteristics of the connective tissues (distribution and thickness) differ among muscles, being of high variability in the lower limb. This variability is of great clinical importance in determining the prognosis of muscle injuries. Recently, three classification systems, the Munich consensus statement, the British Athletics Muscle Injury classification, and the FC Barcelona-Aspetar-Duke classification, have been proposed to assess the severity of muscle injuries. A protocolized approach to the evaluation of MRI findings is essential to accurately assess the severity of acute lesions and to evaluate the progression of reparative changes. Certain MRI findings which are seen during recovery may suggest muscle overload or adaptative changes and appear to be clinically useful for sport physicians and physiotherapists.

COVID-19 pandemic is a global health matter. The disease spread rapidly across the globe and brought the world of sports to an unprecedented stoppage. Usual symptoms of the disease are fever, cough, myalgia, fatigue, slight dyspnoea, sore throat and headache. In more severe cases, dyspnoea, hypoxaemia, respiratory failure, shock and multiorgan failure occur. This appears to be a self-limiting phenomenon related to individuals with coexisting medical conditions, such as hypertension, diabetes and cardiovascular disorders. Nevertheless, cases have been reported in professional soccer players in extremely good fitness condition, demonstrating that athletes are not spared by the disease. Despite COVID-19 clinical manifestations are mainly respiratory, major cardiac complications are being reported, leading to acute myocarditis. One difficulty is that symptoms of COVID-19 vary among individuals, with athletes being affected with no apparent sign of the disease. This could be a real danger for amateur or professional athletes when returning to their usual training and thus to play. Another threat is that the lock-down policies did not allow most athletes to follow their usual training routines. There is thus a need for a careful approach by the sports medicine community to ensure safety of all athletes before they return to sport. Here, we propose evaluation guidelines of fitness and health of athletes to (1) reduce any lethal risk of practice, especially myocarditis and sudden cardiac death; (2) evaluate the combined consequences of the disease and detraining on the physical abilities and biological profile of athletes; and (3) monitor postinfection fatigue symptoms.

BackgroundAcute muscle injuries in elite athletes are responsible for a large portion of time loss injuries.AimTo describe the frequency, the anatomic distribution, and severity of imaging-detected acute muscle injuries among athletes who competed in the Rio de Janeiro 2016 Summer Olympics.MethodsWe recorded all sports injuries reported by the National Olympic Committee medical teams and the Organising Committee medical staff during the 2016 Summer Olympics. Imaging of acute muscle injuries was performed at the IOC’s polyclinic within the Olympic Village using ultrasound and 3.0 T and 1.5 T MRI scanners. The assessment of images was performed centrally by three musculoskeletal radiologists. The distribution of injuries by anatomic location and sports discipline and the severity of injuries were recorded.ResultsIn total, 11 274 athletes from 207 teams were included. A total of 1101 injuries were reported. Central review of radiological images revealed 81 acute muscle injuries in 77 athletes (66% male, mean age: 25.4 years, range 18–38 years). Athletics (track and field) athletes were the most commonly affected (n=39, 48%), followed by football players (n=9, 11%). The majority of injuries affected muscles from lower limbs (n=68, 84%), with the hamstring being the most commonly involved. Most injuries were grade 2 injuries according to the Peetrons classification (n=44, 54%), and we found 18 injuries exhibiting intramuscular tendon involvement on MRI.ConclusionImaging-detected acute muscle injuries during the 2016 Summer Olympics affected mainly thigh muscles in athletics disciplines.

ABSTRACT Objective: To identify the incidence of injuries, their main characteristics, and the way they were managed throughout 2016 in two major series of a professional soccer championship in São Paulo, Brazil. Methods: This prospective study used an electronic questionnaire previously developed by the Medical Committee of the Paulista Soccer Federation which was sent to the team doctors after each match. Results: Two hundred and fifty-nine injuries occurred during 361 matches, and the incidence of injury per 1000 hours of game play was 21.32. Strikers were the most affected by injury; the most frequent diagnosis was muscle injury and the legs were predominantly affected. Most of the injuries occurred in the last 15 minutes of the first half and only 7.7% required surgical treatment. Conclusions: Muscle injuries were the most frequent, with most occurring in forwards and in the legs. Approximately half of the injuries occurred after contact and the vast majority was treated without surgery. MRI was the most requested exam and most injuries were classified as moderate (8 to 28 lost play days).

SummaryStudy aim: This study compared the effects of intermittent negative pressure therapy (INPT) vs. active recovery therapy (ART) on post-match physiological parameters such as serum CK level and skin temperature of the lower limbs in elite soccer players.Material and methods: Twenty healthy male professional soccer players from a Brazilian first division soccer club were enrolled in this randomized, parallel arm, open label, comparative study. After participating in 2 soccer matches, they were randomly assigned to two groups (n = 10) to receive a 30-min session of INPT (intermittent exchange of hypobaric pressure range 33 to 51 mmHg) or ART (self-myofascial release, mobility and stability exercises, and cycle ergometer exercise). The intervention was conducted after a match with assessments immediately before and after the intervention and again 24 h after the intervention.Results: A significant interaction effect (F2,36 = 4.503, p = 0.018, η2 = 0.130) was observed, indicating that the decrease of CK from pre-intervention to 24 h post-intervention was greater in the INPT than in the ART group. Lower limb skin temperature was significantly lower after INPT than after ART (p < 0.003).Conclusions: Serum CK level and skin temperature of lower limbs showed better recovery up to 24 h after the intervention with INPT in elite soccer players.

  Se ha comprobado y establecido que alrededor del 66% de los componentes del rendimiento y estado del atleta se explican por los factores hereditarios. Dos de los polimorfismos genéticos mas estudiados con relación al rendimiento deportivo en la ultima década, son el ACTN3 R577X y el ACE I/D. El objetivo de este estudio fue resumir las posibles asociaciones de ambos polimorfismos y el rendimiento en jugadores de fútbol, determinando la combinación alélica y genotípica que más destaca en esta población y, además, observar las relaciones de estos a nivel físico y fisiológico. Para la realización de este estudio se llevaron a cabo dos fases, una primera de revisión bibliográfica y una segunda fase de clasificación y análisis de la información. Los estudios evidencian una mayor influencia de los alelos ACE-D y ACTN-R, y de los genotipos ACE-ID y ACTN-RR. Se observó que los sujetos con estas combinaciones tenían mejores rendimientos es pruebas de velocidad y fuerza. Por otro lado, el polimorfismo ACTN3 está directamente relacionado con las lesiones musculares. En conclusión, se pudo observar una relación entre los polimorfismos genéticos y el rendimiento en jugadores de fútbol. Los componentes genéticos se pueden integrar como un nuevo componente dentro de la caracterización del deporte y como una herramienta dentro de un modelo de identificacción y detección de talentos en el fútbol juvenil. Además, los biomarcadores genéticos podrían ser responsables en un futuro, del estudio del riesgo de lesiones para que se optimice mucho más el rendimiento en el fútbol profesional. Abstract. It has been verified and established that around 66% of the components of the athlete's performance and state are explained by hereditary factors. Two of the most studied genetic polymorphisms in relation to sports performance in the last decade are ACTN3 R577X and ACE I/D. The aim of this study was to summarize the possible associations of both polymorphisms and the performance in soccer players, determining the allelic and genotypic combination that stands out the most in this population and, also, to observe their relationships at the physical and physiological level. In order to complete this study, two phases were carried out, the first one of literature review and, the second one which covered the information classification and analysis. The studies show a greater influence of the ACE-D and ACTN-R alleles, and higher presence of the ACE-ID and ACTN-RR genotypes. Subjects with these combinations were found to perform better on speed and strength tests. On the other hand, the ACTN3 polymorphism is directly related to muscle injuries. In conclusion, a relationship between genetic polymorphisms and performance in soccer players could be observed. Genetic components can be integrated as a new component within the characterization of sport and as a tool within a model of identification and detection of talents in youth soccer. In addition, genetic biomarkers could be responsible, in the future, for the study of the risk of injury so that performance in professional soccer is much more optimized.

Background/Aims: CD24 is a highly glycosylated mucin-like antigen on the cell surface, which has recently emerged as a novel oncogene and metastasis promoter. We performed bioinformatics analysis to investigate whether CD24 can serve as a prognostic indicator in breast cancer. Methods: CD24 expression was assessed using SAGE Genie tools and Oncomine analysis. The PrognoScan database, Kaplan-Meier Plotter, and bc-GenExMiner were used to identify the prognostic roles of CD24 in breast cancer. Results: We found that CD24 was more frequently overexpressed in breast cancer than in normal breast tissue and correlated with worse prognosis. Meanwhile, high CD24 expression was associated with increased risk of HER2, basal-like, triple-negative breast cancer, and higher Scarff-Bloom-Richardson grade. Data mining in multiple big databases confirmed a positive correlation between CD24 mRNA expression and SDC1 mRNA expression in breast cancer tissue. Conclusions: Our findings suggest that CD24 overexpression is more common in breast cancer than in corresponding normal tissue. In addition, CD24 and SDC1 can serve as prognostic indicators for breast cancer. However, large-scale and comprehensive research is needed to further confirm these results.

Introduction According to the World Health Organization, in 2017, musculoskeletal diseases were the major contributors to global disability. Considering the exercise of functions in a professional context as an essential component in the daily life of human beings, it is in this environment that many of these injuries arise. The serious economic, labour and social repercussions that this type of injuries can cause brings us to the importance of analysing the current prevalence of these events in several industries, as well as the most affected body areas. Methods A literature search was carried out in the Pubmed and Web of Science databases, of articles published after 2015. The keywords used were “employee”, “skeletal muscle”, “injuries” and “industry/ sector”. This research resulted in 132 articles, of which 37 were revised to the full text and assessed their quality, which allowed the selection of 15 articles for a consequent analysis. Results Among the various industries, the tanning industry was the one with the highest global prevalence of musculoskeletal injuries (89.1%), 94.5% in females and 85% in males. In general, the prevalence of this type of injury in workers from different industries was around 70%. In most of the industries analysed (such as food, construction and textiles), the back/ lumbar area was the area most described as the origin of these injuries, with the exception of the printing industry, which reported a higher prevalence at the shoulder level. However, the back was the least identified region in the printing industry, being replaced, in this case, by the shoulder region. Discussion / Conclusion In general, and according to the data obtained, industrial workers are affected by a prevalence of musculoskeletal injuries that can vary between about 55% and 90%. The most affected regions of the body include the back, followed by shoulders, lower limbs and neck. The female sex was shown to be the most susceptible gender to contract musculoskeletal injuries, with respect to industrial workers.
