Fatores de adesão e abandono da prática desportiva em adolescentes escolares

Introdução: Na prática desportiva, os aspectos motivacionais são estabelecidos como um dos principais subsídios que incentivam o sujeito à ação. Objetivo: O objetivo dessa pesquisa foi identificar os fatores que levam a adesão e ao abandono do desporto escolar por parte de adolescentes. Métodos: Esta pesquisa caracteriza-se como sendo um estudo de campo, descritivo, analítico de corte transversal, realizada com 367 adolescentes escolares de ambos os sexos da rede pública do município de Juazeiro do Norte. Foi utilizado uma adaptação do questionário de motivos de início, manutenção, mudança e abandono (MIMCA). As análises estatísticas foram conduzidas pelo software estatístico JASP através de análise descritiva. O Teste t foi utilizado para verificar a existência de diferentes fatores motivacionais entre os sexos dos adolescentes. Resultados: Os resultados apontam existir diferenças estatisticamente significativas entre os fatores motivacionais para adesão e abandono da prática desportiva quando comparado entre os sexos. Destacam-se os seguintes fatores: Para adesão à prática desportiva (Superar a mim mesmo; Amadurecer pessoalmente; Se pratica no bairro; Influência dos pais; Poder competir; Porque tenho condições físicas; Por ter amigos que praticam este esporte; Instalações perto de casa; Influência dos irmãos; Manter-me em forma; Divertir-me). Para abandono (Se meus pais não gostassem do meu esporte; Se meu (minha) namorado\a fosse um obstáculo para a prática do meu esporte; Se não me desse bem com o treinador). Conclusão: Conclui-se que adolescentes escolares têm motivações de adesão e de abandono diferentes no que se trata da prática desportiva. ABSTRACT. Factors of adhesion and abandonment of sports practice in school adolescents. Background: In sports, motivational aspects are established as one of the main incentives that encourage the subject to action. Objective: The objective of this research was to identify the factors that lead to the adherence and abandonment of school sport by adolescents. Methods: This research is characterized as a field study, descriptive, with quantitative approach and cross-section. This study was conducted with 367 schoolchildren of both sexes from the public network of the municipality of Juazeiro do Norte. An adaptation of the questionnaire of reasons for initiation, maintenance, change and abandonment (MIMCA) was used. Statistical analyzes were conducted by JASP statistical software through descriptive analysis. The test t was used to verify the existence of difference the motivational factors between the sex of the adolescents. Results: The results indicate that there are statistically significant differences between the motivational factors for adherence and abandonment of sports practice when compared between the sex of the individual. The following factors stand out: For adherence to sports (Overcoming myself, To mature in person, To practice in the neighborhood, Influence of parents, To compete, Because I have physical conditions, To have friends who practice this sport, Facilities close to home, Influence of siblings, Keep me in shape, Have fun). For abandonment (If my parents did not like my sport, if my boyfriend was an obstacle to the practice of my sport, if I did not get on well with the coach.) Conclusion: It is concluded that school adolescents have motivations for adherence and of different abandonment when it comes to sports

Use of big data in the surveillance of veterinary diseases: early detection of tick paralysis in companion animals

Background: Tick paralysis, resultant from envenomation by the scrub-tick Ixodes holocyclus, is a serious threat for small companion animals in the eastern coast of Australia. We hypothesise that surveillance systems that are built on Internet search queries may provide a more timely indication of high-risk periods more effectively than current approaches. Methods: Monthly tick paralysis notifications in dogs and cats across Australia and the states of Queensland (QLD) and New South Wales (NSW) were retrieved from Disease WatchDog surveillance system for the period 2011-2013. Internet search terms related to tick paralysis in small companion animals were identified using Google Correlate, and corresponding search frequency metrics were downloaded from Google Trends. Spearman's rank correlations and time series cross correlations were performed to assess which Google search terms lead or are synchronous with tick paralysis notifications. Results: Metrics data were available for 24 relevant search terms at national level, 16 for QLD and 18 for NSW, and they were all significantly correlated with tick paralysis notifications (P < 0.05). Among those terms, 70.8, 56.3 and 50 % showed strong Spearman's correlations, at national level, for QLD, and for NSW respectively, and cross correlation analyses identified searches which lead notifications at national or state levels. Conclusion: This study demonstrates that Internet search metrics can be used to monitor the occurrence of tick paralysis in companion animals, which would facilitate early detection of high-risk periods for tick paralysis cases. This study constitutes the first application of the rapidly emerging field of Internet-based surveillance to veterinary science

Detection of Spirocerca lupi and an unknown Trichinella-like nematode in raccoon (Procyon lotor).

The raccoon Procyon lotor (Carnivora: Procyonidae) is an invasive species of growing importance for the introduction of alien pathogens or as additional hosts for autochthonous pathogens in Europe, including zoonotic parasites. As the population is steadily increasing and outcompeting the red fox (Vulpes vulpes) in Germany, the consumption of raccoon meat raises concerns about pathogens they may transmit. Therefore the presence of Trichinella larvae was here investigated in muscle samples (n = 904) of raccoons from northern Germany. No Trichinella larvae were found, thus confirming the general low occurrence of this parasite in Germany. However, Spirocerca lupi (n = 12) and an unidentified Trichinella-like nematode (n = 1) were accidently detected in the examined samples. The first is not a zoonotic parasite but has a high veterinary relevance as it can cause severe diseases in dogs. It is the first documented autochthonous infection of this nematode in Germany. The larvae of an unidentified Trichinella-like nematode were found in high abundance in all examined muscles of one raccoon, though they could not be identified to species level. Histological investigation revealed intramuscular cystic structures. This is the largest study investigating muscular parasites of raccoons in Europe so far, which suggests that this invasive animal species is infected by S. lupi and by a yet unknown Trichinella -like parasite

Índice de vegetação como subsídio na identificação de áreas com potenciais a desertificação

A desertificação é um problema ambiental que afeta centenas de hectares de terras localizadas nas regiões secas de várias partes do planeta. Para identificação das áreas em processo de desertificação vários mecanismos vêm sendo empregados, entre eles o sensoriamento remoto. Neste contexto, o objetivo deste trabalho é identificar as áreas com potenciais à desertificação nos municípios de Santa Maria da Boa Vista e Lagoa Grande, Pernambuco, através do SAVI (Soil Ajusted Vegetation Index). Para isto, foram empregadas duas imagens obtidas pelos satélites Landsat 5 e Landsat 8 referente aos anos de 2005 e 2015, respectivamente. Os resultados indicam que os dois municípios apresentam áreas com diferentes potenciais à desertificação, principalmente, as correlacionadas à caatinga esparsa e as regiões com solo exposto. Áreas que oscilaram entre queda e aumento de espaços ocupados entre os dois anos devido à sensibilidade do índice aos eventos pluviométricos que modificaram a estrutura da cobertura vegetal. Neste contexto, o SAVI mostrou-se eficiente na identificação das áreas com diferentes potencias a desertificação na área de estudo, porém, deve ser empregado com auxílio de outro método de mapeamento, visto que, os reflexos das chuvas na vegetação podem comprometer o processo de identificação das áreas de risco

Spermatic and seminal evaluation in Young Boer goats born in the rainy and dry season

Este trabalho objetivou determinar motilidade, turbilhonamento, vigor, defeitos maiores e menores dos espermatozoides de caprinos da raça Boer durante a estação chuvosa (n = 11) e seca (n = 11). Na estação chuvosa, a concentração espermática variou de 0,90 ± 1,46 x 109/mL a 2,7 x 109/mL, a motilidade progressiva de 16,0% a 62,0%, o turbilhonamento de 0,3 a 2,6 , vigor de 1,1 a 2,8 , defeitos maiores de 18,3% a 3% e menores de 16,1% a 3,4%. Na estação seca, a concentração espermática variou de 0,96 x 109/mL a 2,15 x 109/mL, a motilidade progressiva de 35,4% a 64,1%, o turbilhonamento de 1,7 a 3,1, vigor de 2,0 a 3,0, defeitos maiores de 16,9% a 4,2% e menores de 17,5% a 3,2%. Foi registrada correlação positiva (P < 0,05) entre motilidade espermática vs turbilhonamento espermático, respectivamente, para a estação chuvosa e seca, motilidade espermática vs vigor espermático bem como negativa entre motilidade progressiva vs defeitos maiores dos espermatozoides e entre motilidade progressiva e defeitos menores dos espermatozoides. Dessa forma, pode-se concluir que machos caprinos da raça Boer nascidos na estação seca têm atraso de três meses do início da maturidade sexual em comparação àqueles nascidos na estação chuvosa. __________________________________________________________________________________________ ABSTRACTThis study had the objective to distinguish spermatic and seminal parameters in animals born during the dry (n=11) and rainy (n=11) seasons. In the rainy season, the spermatic concentration ranging from 0.90 to 2.7 x 109/mL, the progressive motility from 16.0% to 62.0%, the mass movement from 0.3 to 2.6, vigor from 1.1 to 2.8, major sperm defects of 18.3% to 3 % and minor sperm defects from 16.1% to 3.4% . In the dry season, the spermatic concentration varied from 0.96 to 2.15 x 109/mL, the progressive motility from 35.4% to 64.1%, the mass movement form 1.7 to 3.1, vigor from 2.0 to 3.0, major sperm defects from 16.9% to 4.2% and minor sperm defects from 17.5% to 3.2%. It was observed positive correlation between spermatic motility versus spermatic mass movement, spermatic motility versus spermatic vigor as well as a negative correlation between motility versus major sperm defects of the spermatozoa and between motility and spermatozoa smaller defects respectively, in the rainy and dry seasons. Based on these results we conclude that Boer male goats born in dry season have sexual retardation of three months in comparison to those born in the rainy station

Parasites with zoonotic potential in canine fecal samples from Garanhuns, Pernambuco, Brazil

Among the gastrointestinal parasites of dogs that present public health importance, the species of the genus Ancylostoma and Toxocara are the most frequently detected, and have been important cause of soil contamination. The aim of this study was to detect gastrointestinal parasites in dog’s feces collected in households, streets and public squares of the city of Garanhuns, Pernambuco, Brazil. Fecal samples (n = 640) were collected in the environment and evaluated by parasitological methods of Willis-Mollay and Hoffman, Pons and Janer. Out of all samples, 51.09% (327/640) were positive for gastrointestinal parasites. In particular, in 70.94% (232/327) of the samples were detected eggs of Ancylostoma spp., and in 11.01% (36/327) coinfection by Ancylostoma spp. and Toxocara canis. In conclusion, the presence of eggs of zoonotic parasites in feces collected from the environment in the city of Garanhuns represent a risk for the transmission of Cutaneous Larva Migrans and Visceral Larva Migrans for the human population

Prognostic implications of the ID1 expression in acute myeloid leukemia patients treated in a resource-constrained setting

Introduction: The aberrant expression of the inhibitor of DNA binding (ID1) gene has been frequently associated with the leukemogenesis and prognostication acute myeloid leukemia (AML), although its clinical importance has never been investigated in patients treated outside well-controlled clinical trials. Methods: Using quantitative real-time polymerase chain reaction, we investigated the role of the ID1 expression in the clinical outcomes of non-selected patients with acute myeloid leukemia treated in a real-life setting. Results: Overall, 128 patients were enrolled. Patients with high ID1 expression had a lower 3-year overall survival (OS) rate of 9%, with the 95% confidence interval (95%CI) at 3 to 20%, compared to patients with a low ID1 expression (22%, 95%CI: 11 - 34%) (p = 0.037), although these findings did not retain significance after adjustment (hazard ratio (HR): 1.5, 95%CI: 0.98 - 2.28; p = 0.057). The ID1 expression had no impact on post-induction outcomes (disease-free survival, p = 0.648; cumulative incidence of relapse, p = 0.584). Conclusions: Although we are aware thar our data are confronted with many variables that cannot be fully controlled, including drug unavailability, risk-adapted treatment, comorbidities and the time from diagnosis to treatment initiation, we are firm believers that such an initiative can provide more realistic data on understudied populations, in particular those from low- and middle-income countries.</p
