Injuries prevalence in elite male artistic gymnasts

A proposta deste estudo foi investigar a prevalência de lesões na ginástica artística masculina de alto rendimento. Vinte ginastas brasileiros da categoria adulta, com 23,1 ± 6,5 anos, 13,9 ± 5,0 anos de prá- tica no esporte e 36,5 ± 4,7 horas de treino semanais, participaram do estudo. Os atletas responderam o questionário de lesões referidas, formulado a partir de estudos da literatura, para obter informações sobre as características e circunstâncias das lesões. Foram considerados dados sobre o aparelho ou evento do treinamento em que ocorreu a lesão, o local anatômico lesionado, o tecido biológico afetado e o retorno às atividades após a lesão. Os dados foram avaliados por meio de estatística descritiva, a partir das frequências absolutas e relativas. A sobrecarga de treinamento e os aparelhos solo, cavalo com alças e salto sobre a mesa foram os eventos com maior frequência de lesões. Em relação ao local anatômico, tornozelo, mãos/dedos e ombro foram as regiões mais citadas. Os tecidos ligamentares e ósseo, bem como a cápsula articular foram os tecidos biológicos mais afetados. Em relação ao retorno às atividades, 56% relataram melhora, 33% reportaram retorno ao mesmo nível prévio à lesão e 10% relataram piora do desempenho após retorno às atividades. As lesões na ginástica artística masculina estão associadas às demandas mecânicas do esporte. A análise dos fatores de risco contribui no entendimento dos mecanismos das lesões na ginástica, bem como pode auxiliar em estratégias efetivas de prevenção.The purpose of this study was to investigate the injuries prevalence in men elite artistic gymnasts. Twenty Brazilian senior gymnasts, aged 23.1 ± 6.5 years, 13.9 ± 5.0 years of practice and 36.5 ± 4.7 hours per week training, participated in this study. The athletes answered a morbidity questionnaire, formulated according to studies from the literature, for information on the injuries’ characteristics and circumstances. Information about the injury circumstances (gymnastic apparatus, overload training and physical exercises), the anatomic site injured, the affect biological tissue and the return to training after injury treatment were evaluated. Data were analyzed by descriptive statistics, absolute and relative frequencies. The training overload, and floor, pommel horse and vault were the events that presented higher injuries frequency. In relation to anatomic site, ankle, hands/fingers and shoulder were the most cited regions. The ligament, bone and articular capsule were the most affected biological tissues. In relation to gymnasts’ return to their sports activities, 56% of them reported a better condition at return, 33% reported to have returned at the same fitness level and 10% indicated that they were in a worse condition when they returned to the sports activities. The men’s artistic gymnastics injuries are related to the mechanical demands of this sport. The analysis of risk factors helps in understanding the injuries mechanisms in gymnastics, and provides relevant information that can assist in effective prevention strategies

Timpanismo e empiema de bolsa gutural conseqüente a garrotilho

Strangles is a contagious disease that affect the equine upper respiratory tract, frequent and important, that causes pyrexia, nasal discharge and secretion of pus from lymph nodes. Often occur in young equines and is caused by Streptococcus equi â-hemolytic. Some times the strangles can promote results how sinusitis, guttural pouch empyema and distant abscess formation, main in the mesentery. The objective of this paper is study of timpany and empyema of guttural pouch associated with strangles, clinic and cirurgic, happened in a young horse.Garrotilho é uma doença infecto-contagiosa do trato respiratório superior dos eqüídeos, freqüente e importante, que causa pirexia, descarga nasal e abscedação dos linfonodos adjacentes. Acomete basicamente equídeos jovens, e é causada pelo Streptococcus equi â-hemolítico. Ocasionalmente, o garrotilho pode deixar seqüelas como sinusites, empiema das bolsas guturais e formação de abcessos à distância, principalmente no mesentério. O objetivo deste estudo é avaliar o timpanismo e empiema de bolsa gutural, clínico e cirúrgico, conseqüente a garrrotilho, ocorrido num eqüino jovem

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

First Record of the Alien and Invasive Polychaete <i>Laonome triangularis</i> Hutchings & Murray, 1984 (Annelida, Sabellidae) in Italian Waters

In recent years, the introduction of alien and invasive marine species in the Mediterranean Sea has rapidly increased. Laonome triangularis is a sabellid worm, native to the Australian coasts. Its first record in the Mediterranean Sea dates back to 2009 and, in this area, it is currently labeled as an allochthonous species. In the present work, we report the fìrst record of this polycheate in Italian waters and we provide some diagnostic features that are useful to identify the species

Identificação de potenciais plantas hospedeiras alternativas de Xanthomonas campestris pv. viticola

Este estudo teve como objetivo identificar possíveis hospedeiras alternativas de Xanthomonas campestris pv. viticola (Xcv), visando a fornecer subsídios para o manejo do cancro bacteriano da videira. Vinte e seis espécies vegetais foram inoculadas artificialmente com o isolado Xcv3 e mantidas em condições de casa de vegetação, sendo avaliada a evolução sintomatológica da doença, como manchas necróticas angulares e lesões nas nervuras. O Xcv3 foi reisolado a partir de cada hospedeiro alternativo com sintomas, sendo identificado por PCR (Polymerase Chain Reaction), com iniciadores específicos. As espécies inoculadas que apresentaram os sintomas típicos da doença foram Glycine sp., Senna obtusifolia, Desmodium discolor, Amaranthus deflexus, Azadirachta indica, Solanum lycopersicum e Vigna unguiculata. As espécies da família Poaceae, Bidens pilosa, Emilia fosbergii, Praxelis pauciflora, Macroptilium lathyroides e Portulaca oleracea não apresentaram sintomas durante o período da avaliação
