ABSTRACT
Objetivo: Identificar a prevalência de queixas álgicas em praticantes de Brazilian Jiu-Jitsu (BJJ), as queixas que levaram ao afastamento dos treinamentos e as queixas de lesões prévias. Métodos: Trata-se de um estudo transversal, observacional e descritivo que incluiu praticantes regulares de BJJ do sexo masculino, com idades entre 18 e 40 anos. Foi elaborado um questionário para identificar o perfil dos praticantes: idade, graduação, tempo de prática da arte marcial, frequência de treinos, prática de outras atividades física e frequência. Para a investigação das queixas álgicas, foi aplicado o Questionário Nórdico de Sintomas Osteomusculares QNSO, versão em português adaptada. Os dados foram registrados no programa Microsoft Excel 365 e foi realizada estatística descritiva. Resultados: Os 52 participantes da pesquisa possuíam idade média de 32 anos e tempo médio de 9 anos de prática de Jiu-Jitsu, 50% deles possuía graduação de faixa azul. Os praticantes apresentaram 45 relatos de queixas na semana anterior a aplicação do QNSO, 76 relatos no ano anterior, 43 relatos que levaram os praticantes a se afastarem do treinamento e 20 relatos de lesões prévias no ano anterior. Conclusão: A maior prevalência de queixas nos 7 dias prévios a aplicação do QNSO, ocorreu em joelhos, coluna lombar e quadril-coxas, e nos 12 meses prévios ocorreu em joelhos, coluna lombar e ombros. A maior prevalência que levou os praticantes ao afastamento dos treinamentos nos 12 meses prévios ocorreu em joelhos, coluna lombar e tornozelo-pés, e as queixas de lesões prévias ocorreram em joelhos, punhos e ombros.
Objective: To identify the prevalence of pain complaints in Brazilian Jiu- Jitsu (BJJ) practitioners, the complaints that led to withdrawal from training and the complaints of previous injuries. Methods: This is a cross-sectional, observational and descriptive study that included regular male BJJ practitioners aged between 18 and 40 years. A basic questionnaire was created to collect variables: age, graduation, time practicing martial art, frequency of training, practice of other physical activities and frequency. For the investigation of pain complaints, the Nordic Questionnaire of Musculoskeletal Symptoms - NQSO, adapted Portuguese version, was applied. Data were recorded in the Microsoft Excel 365 program and descriptive statistics were performed. Results: The 52 research participants had average an age of 32 years old and average time of 9 years of BJJ practice, 50% of them were blue belt graduation. The practitioners presented 45 reports of complaints in the week before the application of NQSO, 76 reports in previous year, 43 reports that led to withdrawal training and 20 reports of previous injuries in the previous year. Conclusion: The highest prevalence of complaints in the previous 7 days of the application of NQSO occurred in the knees, lumbar spine and hip- thighs, and in the previous 12 months occurred in the knees, lumbar spine and shoulders. The major prevalence that led to withdrawal training in the previous 12 month occurred in the knees, lumbar spine and ankle-foots, and the complaints of previous injuries occurred in the knees, wrists and shoulders.
Objetivo: Identificar la prevalencia de quejas de dolor en practicantes de Brazilian Jiu-Jitsu (BJJ), las quejas que llevaron a la retirada del entrenamiento y las quejas de lesiones anteriores. Métodos: Se trata de un estudio transversal, observacional y descriptivo que incluyó practicantes regulares de BJJ del sexo masculino, con edades entre 18 y 40 años. Se elaboró un cuestionario para identificar el perfil de los practicantes: edad, grado, tiempo de práctica del arte marcial, frecuencia de entrenamiento, práctica de otras actividades físicas y frecuencia. Para la investigación de las quejas de dolor, se aplicó el Cuestionario Nórdico de Síntomas Musculoesqueléticos CNSO, versión portuguesa adaptada. Los datos se registraron en el programa Microsoft Excel 365 y se realizó estadística descriptiva. Resultados: Los 52 participantes de la investigación tenían una edad promedio de 32 años y un tiempo promedio de práctica de BJJ de 9 años, el 50% de ellos tenían graduación de cinturón azul. Los practicantes presentaron 45 reportes de denuncias en la semana anterior a la aplicación de la CNSO, 76 reportes en el año anterior, 43 reportes que llevaron a los practicantes a retirarse del entrenamiento y 20 reportes de lesiones anteriores en el año anterior. Conclusión: La mayor prevalencia de quejas en los 7 días previos a la aplicación de la CNSO se presentó en rodillas, columna lumbar y cadera-muslos, y en los 12 meses anteriores se presentó en rodillas, columna lumbar y hombros. La prevalencia más alta que llevó a los practicantes a retirarse del entrenamiento en los 12 meses anteriores ocurrió en rodillas, columna lumbar y tobillo-pie, y las quejas de lesiones previas ocurrieron en rodillas, muñecas y hombros.
ABSTRACT
Bacteria halo blight (BHB), a coffee plant disease caused by Pseudomonas syringae pv. garcae, has been gaining importance in producing mountain regions and mild temperatures areas as well as in coffee nurseries. Most Coffea arabica cultivars are susceptible to this disease. In contrast, a great source of genetic diversity and resistance to BHB are found in C. arabica Ethiopian accessions. Aiming to identify quantitative trait nucleotides (QTNs) associated with resistance to BHB and the influence of these genomic regions during the domestication of C. arabica, we conducted an analysis of population structure and a Genome-Wide Association Study (GWAS). For this, we used genotyping by sequencing (GBS) and phenotyping for resistance to BHB of a panel with 120 C. arabica Ethiopian accessions from a historical FAO collection, 11 C. arabica cultivars, and the BA-10 genotype. Population structure analysis based on single-nucleotide polymorphisms (SNPs) markers showed that the 132 accessions are divided into 3 clusters: most wild Ethiopian accessions, domesticated Ethiopian accessions, and cultivars. GWAS, using the single-locus model MLM and the multi-locus models mrMLM, FASTmrMLM, FASTmrEMMA, and ISIS EM-BLASSO, identified 11 QTNs associated with resistance to BHB. Among these QTNs, the four with the highest values of association for resistance to BHB are linked to g000 (Chr_0_434_435) and g010741 genes, which are predicted to encode a serine/threonine-kinase protein and a nucleotide binding site leucine-rich repeat (NBS-LRR), respectively. These genes displayed a similar transcriptional downregulation profile in a C. arabica susceptible cultivar and in a C. arabica cultivar with quantitative resistance, when infected with P. syringae pv. garcae. However, peaks of upregulation were observed in a C. arabica cultivar with qualitative resistance, for both genes. Our results provide SNPs that have potential for application in Marker Assisted Selection (MAS) and expand our understanding about the complex genetic control of the resistance to BHB in C. arabica. In addition, the findings contribute to increasing understanding of the C. arabica domestication history.
ABSTRACT
Aedes aegypti and Aedes albopictus are exotic species in the Americas with high epidemiological relevance as they are vectors of many pathogens. This study aimed at understanding the population dynamics of A. aegypti and A. albopictus and the influence of abiotic factors in an endemic area of dengue. The study was conducted in the urban area of Campo Grande, Mato Grosso do Sul, Brazil, over one year. In seven regions of the city, 50 ovitraps were installed in each neighborhood. The development of the larvae was monitored under controlled laboratory conditions until they reached the adult phase. A total of 50,900 eggs of Aedes sp. were collected, 26,073 of which reached adulthood: 25,496 (97.8 %) A. aegypti and 540 (2.1%) A. albopictus. A. aegypti was observed in all months during the study. The highest number of A. albopictus eggs were collected in June, while in August and September, an absence of this species was noted. Abiotic factors such as temperature, humidity and rainfall were responsible for the observed fluctuations in the mosquito population. The presence of A. albopictus in the urban area of the city is concerning because it could become a potential vector for other arboviruses that afflict human populations. The occurrence of these species in Campo Grande reinforces the need for constant entomological and epidemiological surveillance so that informed actions could be taken to decrease potential breeding sites.
