FUNCTIONAL ASSESSMENT OF THE SHOULDER IN JIU-JITSU BLACK BELT ATHLETES.

OBJECTIVE: To assess the epidemiological profile of Jiu-Jitsu black belt athletes, including the prevalence of pain and shoulder function. METHODS: Cross-sectional study carried out with Jiu-Jitsu athletes from 2014 to 2016. The studied variables were: sex, age, dominant limb, weight, height, profession, time of Jiu-Jitsu practice, weekly training hours, other practiced sports, comorbidities, injuries and previous surgeries, medications and habits. For the functional assessment of the shoulder, the ASES Score was used. RESULTS: 53 male athletes were evaluated. There was a prevalence of alcohol consumption (60.4%) and supplement use (32.1%). The practice of other sports included weight training (49.1%) and other martial arts (17%). There was a prevalence of knee (66.0%) and shoulder (52.8%) injuries and, in some cases, the need for surgical procedures. There was a prevalence of shoulder pain (73.6%) and more than half of the athletes (52.9%) had minimal or moderate limitation of shoulder function. CONCLUSION: Jiu-jitsu black belt athletes often have a history of injuries, with the shoulder being the second most affected body part. In more than half of the athletes, there was a prevalence of shoulder pain and functional limitation, according to the ASES Score. Level of evidence III, Retrospective comparative study.

OBJETIVO: Avaliar o perfil epidemiológico de atletas faixas-pretas de jiu-jitsu, incluindo a prevalência de dor e a função do ombro. Métodos: Estudo transversal realizado com atletas de jiu-jitsu entre 2014 e 2016. As variáveis estudadas foram: sexo, idade, membro dominante, peso, altura, profissão, tempo de prática do esporte, horas semanais de treino, outros esportes praticados, comorbidades, lesões e cirurgias prévias, medicamentos e hábitos. Para a avaliação funcional do ombro, foi utilizado o escore American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES). RESULTADOS: Foram avaliados 53 atletas, todos do sexo masculino. Houve alta prevalência de consumo de bebida alcoólica (60,4%) e uso de suplementos (32,1%). A prática de outros esportes incluiu musculação (49,1%) e outras artes marciais (17%). Houve alta prevalência de lesões no joelho (66,0%) e no ombro (52,8%), e em alguns casos houve a necessidade de procedimentos cirúrgicos. Verificou-se alta prevalência de dor no ombro (73,6%), sendo que mais da metade dos atletas (52,9%) apresentaram limitação mínima ou moderada da função do ombro. Conclusão: Atletas faixas-pretas de jiu-jitsu frequentemente apresentam histórico de lesões, sendo o ombro o segundo local mais acometido. Houve alta prevalência de dor nos ombros e limitação funcional conforme o escore ASES em mais da metade dos atletas. Nível de evidência III, Estudo comparativo retrospectivo.

Cell-derived microvesicles in infective endocarditis: Role in diagnosis and potential for risk stratification at hospital admission.

OBJECTIVES: To characterize the plasmatic profile of cell-derived microvesicles (MVs) at diagnosis and during the treatment of patients with infective endocarditis (IE). METHODS: Blood samples from 57 patients with IE were obtained on 3 consecutive moments: upon admission (T0), at 2 weeks (T1), and at the end of treatment (T2), and were compared with 22 patients with other bacterial infections. MPs were measured by flow cytometry and labeled for specific cell markers of CD45 (leukocytes), CD66b (neutrophils), CD14 (monocytes), CD41a (platelets), CD51 (endothelial cells), CD3 (T lymphocyte) and CD235a (erythrocytes). RESULTS: MVs from platelets (pltMVs), leukocytes (leukMVs), neutrophils (neutMVs), monocytes (monoMVs) and lymphocytes (lymphMVs) were significantly more elevated in the patients with IE, compared to the patients with other bacterial infections, despite comparable age, sex, blood counts and C-reactive protein levels. MVs values revealed a relatively stable pattern over time in IE, except for a significant increase in leukMVs and neutMVs in T1. LeukMVs (p = 0.011), neutMVs (p = 0.010), monoMVs (p = 0.016) and lymphMVs (p = 0.020), measured at admission, were significantly higher in IE patients that died during hospitalization in comparison with those that survived. In a multivariable analyses, the levels of neutMVs remained as an independent factor associated with mortality (odds ratio 2.203; 95% confidence interval 1.217 - 3.988; p = 0.009), adjustment for heart failure during the treatment. CONCLUSIONS: Plasma levels of pltMVs, leukMVs, neutMVs, monoMVs and lymphMVs were significantly more elevated in patients with IE than in patients with other bacterial infections at hospital admission. Furthermore, neutMVs at admission have been identified as an independent predictor of mortality in patients with IE. Thus, cell derived MPs may become an important tool in the differential diagnosis and mortality risk assessment early in the course of IE suspected cases.
