RESUMO
Objective:To analyze the characteristics of athletes' sports injuries during the Winter Olympic and Winter Youth Olympic Games. Methods:The information of registered athletes during the 2010, 2014 Winter Olympics and 2012 Winter Youth Olympic Games, including the injury numbers of each sport, damage sites, types and severity of injuries were collected, and the epidemiological characteristics were analyzed. Results:A total of 6370 person-time registered athletes were collected and 789 sports injuries were recorded. The injury rate per 1000 registered athletes was 123.9. An average of 11% of athletes was injured at least once. There was a significant difference in the injury rate among these events (χ2 = 12.301, P = 0.002). Women were more likely to be injured than men (χ2 = 5.220, P = 0.022). The top three sports with the highest injury rate were snowboarding (23.9%), freestyle skiing (23.2%) and Bobsleigh (18.0%); the top three sports with the largest number of injuries were ice hockey (160 person-time, 20.3%), alpine skiing (128 person-time, 16.2%) and snowboarding (113 person-time, 14.3%). The top three most injured sites were knee (54 person-time, 13.6%), head (41 person-time, 10.3%) and lumbar spine/lower back (27 person-time, 6.8%); the top three types of injury were contusion/haematoma/bruise (123 person-time, 30.9%), sprain (dislocation/subluxation or ligamentous rupture) (71 person-time, 17.8%) and strain (muscle rupture/tear or tendon rupture) (47 person-time,11.8%). A total of 251 injuries (31.8%) were expected to result in time loss for the athlete, 81 out of whom were severe injuries (32.3%). Conclusion:There is a mass of sport injuries in winter sports events with different types and severities. The incidence of injury varies with sports, and it is focused on snowboarding, freestyle skiing and Bobsleigh, ice hockey and alpine skiing. It is needed to research the technical characteristics of specific sports, damage risk factors and mechanism to reduce the sports injuries, and to construct green channels for sports injuries, to promote the recovery of function.
RESUMO
Spinal injuries caused by competitive sports are common. Spinal diseases are important issues that needs to be solved urgently in the fields of sports injury. Return to play recommendations are complicated due to a mix of medical factors, social pressures, and limited outcome data. This article reviewed the current situation of athletes return to play after spine and spinal cord injury based on disease classification, including cervical spine (cervical soft tissue injuries, cervical fracture and dislocation, cervical stenosis, cervical disk herniation, stingers and burners), thoracic spine (thoracic fracture), lumbar spine (lumbar strain, lumbar stenosis spondylolysis and spondylolisthesis, lumbar disk herniation), and spinal cord concussion and spinal cord injury. This article also analyzed the criteria for athletes to return to play after spine and spinal cord injuries. It may provide references for future clinical management and consensus/guidelines.
RESUMO
Objective:To Compare and analyze the gut microbiota and biochemical indexes between patients with acute traumatic complete spinal cord injury and healthy subjects. Methods:From May, 2017 to May, 2018, a total of 44 patients with acute traumatic complete spinal cord injury (patient group) and 33 healthy controls (control group) were included. The clinical data and fresh blood, urine and fecal samples of the two groups were collected. The V3-V4 region of 16S rRNA gene was sequenced and analyzed. Results:The abundance of gut microbiota was higher in the patient group than in the control group, and the structural composition was different. Compared with the control group, the expression of Bacteroidetes decreased (P < 0.05), and the expression of Actinobacteria, Proteobacteria, Synergistetes, Saccharibacteria and Cyanobacteria increased in the patient group (P < 0.05). The serum glucose, low density lipoprotein, triglyceride and total cholesterol were significantly higher in the patient group than in the control group (P < 0 05). There was a significant correlation between these elevated markers and intestinal microbial community structure (P < 0.05). Conclusion:There is gut microbiota dysbiosis in patients with acute traumatic complete spinal cord injury, and the changes of the microbiota are related to the elevation of some serum biomarkers.
