Their level of sensitivity and environmental knowledge will play an important role in adequately facing future challenges. This article aims to measure the sustainability awareness of a sample of future graduates in Physical Activity and Sport Sciences in Spain. The literature supports that the sensitivity of these students can be estimated by using the Spanish adaptation of the SCQ-S. This allows for establishing the level of knowledge, attitudes and behaviour pertaining to sustainability in three dimensions: environmental, social and economic. The sample consisted of 170 students (58.8% males; 41.2% females) with a mean age of 20.5 years (±4.039). The overall Cronbach’s alpha showed a fairly good value (α = 0.836). The same was true for the Kaiser–Meyer–Olkin test values (KMO = 0.816) and Bartlett’s sphericity test (p < 0.001). The knowledge construct (4.56 ± 0.53) was the highest descriptive, followed by attitude (4.12 ± 0.59). The lowest value was behaviour (3.79 ± 0.66). By gender, girls obtained the highest sensitivity indexes. In addition, the place of habitual residence and physical activity in the natural environment were related to the overall behaviour of the university students. It is concluded that being in active contact with the natural environment allows us to have a higher level of awareness

Entre ellas, la literatura establece la importancia de la psicología y las técnicas indicadoras de la experiencia adquirida en la disciplina. Este estudio pretende establecer la relación entre determinados constructos que definen el perfil psicológico del deportista con indicadores de habilidad en paracaidismo militar. Para ello, se encuestó a 42 saltadores de 40,86 años (±7,35) pertenecientes al ejército español y a la guardia civil durante la celebración del Campeonato Nacional Militar de paracaidismo que se celebra anualmente, para conocer su nivel de optimismo, resiliencia, bienestar psicológico y burnout. Se concluye que los años de experiencia en paracaidismo y el número de saltos, como indicadores de habilidad, deben ser tomados en cuenta con un mayor nivel de concreción y especificidad, ya que ciertas variables psicológicas pueden aumentar o disminuir dependiendo de ellas. Conviene estudiar cada caso en particular para comprender qué puede ocurrir en el estado del paracaidista y desarrollar estrategias para optimizar el rendimiento deportivo.Multiple variables must be considered when talking about sports performance. Among them, the literature estblishes the importance of psychology and indicator techniques of experience acquired in the discipline. This study aims to establish the relationship between certain constructs that define the psychological profile of the athlete with skill indicators in military parachuting. For this, 42 jumpers aged 40.86 years old (±7.35) belonging to the Spanish army and the civil guard during the celebration of the National Military Championship of Skydiving which is held annually surveyed to know their level of optimism, resilience, psychological well-being, and burnout. It is concluded that the years of skydiving experience and the number of jumps, as indicators of skill, must be taken into account with a higher level of concreteness and specificity since certain psychological variables can increase or decrease depending on them. It is convenient to study each case, in particular, to understand what can happen in the state of the parachutist and develop strategies for optimizing sports performance.Múltiplas variáveis devem ser consideradas quando se fala em desempenho desportivo.

Para tal, foram inquiridos 42 saltadores com 40,86 anos (±7,35) pertencentes ao exército espanhol e à guarda civil durante a celebração do Campeonato Nacional Militar de paraquedismo que se realiza anualmente para conhecer o seu nível de optimismo, resiliência, bem-estar psicológico e esgotamento. Conclui-se que os anos de experiência em paraquedismo e o número de saltos, como indicadores de habilidade, devem ser levados em consideração com maior grau de especificidade, pois certas variáveis psicológicas podem aumentar ou diminuir. É conveniente estudar cada caso em articular para entender o que pode acontecer no estado do paraquedista e desenvolver estratégias para otimizar o desempenho esportivo

Estrogen-related genes and postmenopausal osteoporosis risk

Background To date, more than 150 candidate genes related to osteoporosis have been described, but osteoporosis has increasingly been considered a polygenic disease modulated by environmental factors. It is thought that osteoporosis predisposition, pathology, and treatment response depend on the interaction between different genes or between genes and environmental factors. Objective The aim of this study was to evaluate the relationship between the presence of single nucleotide polymorphisms (SNPs) in the estrogen metabolic pathway and the development of osteoporosis and to determine whether this relationship is monogenic or whether interactions between genes exist. Materials and methods A multicentric study with 1980 postmenopausal Spanish women in fi ve Spanish communities was conducted. The women completed a specifi c questionnaire that inquired about risk factors for osteoporosis. Data on participants ’ bone mineral density were obtained with dual-energy X-ray densitometers, and genetic data were obtained from frozen peripheral blood. Results The digenic protection combinations indicated involvement of the wild-type genotype (WT) of the 3 UTR marker for the CYP19A1 gene, the IVS4 marker of the same gene, and the BMP15 and FSHR genes. Among patients who carried two or more of the genotypes considered ‘ risky ’ , the triple combination among markers of the ESR2 and NRIP1 genes with any of the two mutations of the analyzed markers of the BMP15 gene gave a mean T -score value of 2.32 0.91 ( p 0.02). Conclusion Variants of the new candidate genes ( NRIP and BMP15 ) can predispose patients to osteoporosis

Usefulness of Perfusion CT to Assess Response to Neoadjuvant Combined Chemoradiotherapy in Patients with Locally Advanced Rectal Cancer

RATIONALE AND OBJECTIVES: To prospectively evaluate perfusion computed tomography (CT) for assessment of changes in tumor vascularity after chemoradiation therapy (CRT) in locally advanced rectal cancer and to analyze the correlation between baseline perfusion parameters and tumor response. MATERIALS AND METHODS: Twenty patients with rectal cancer underwent baseline perfusion CT before CRT, and in 11 an examination after CRT was also performed. For each tumor, blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability-surface area product (PS) were quantified. The Mann-Whitney U test compared baseline perfusion parameters of responders and nonresponders and pre- and post-CRT measurements were compared by the Wilcoxon signed-rank test (P < .05 statistically significant for both tests). RESULTS: Baseline BF was significantly lower (P = .013) and MTT was significantly higher (P = .006) in responders. Both were able to discriminate responders from nonresponders with a sensitivity of 80% and 100% and a specificity of 73.3% and 86.7%, respectively, for BF and MTT. Baseline BV and PS were not significantly different in responders and nonresponders. Perfusion parameters changed significantly in post-CRT scans compared to baseline: BF (P = .003), BV (P = .003), and PS (P = .008) decreased, whereas MTT increased (P = .006). CONCLUSION: Baseline BF and MTT can discriminate patients with a favorable response from those that fail to respond to CRT, potentially selecting high-risk patients with resistant tumors that may benefit from an aggressive preoperative treatment approach

Fatigue analysis of thin AlMgSi welded joints under constant and variable amplitude block loadings

This paper reports the fatigue behaviour of thin AlMgSi1 aluminium alloy weldments and the improvement in fatigue strength due to post-weld treatments. Several fatigue tests were performed using two distinct types of thin welded joints, T and single lap, manufactured using a 6xxx series aluminium alloy, and the efficiency of fatigue life improvement techniques, such as post-weld heat treatment and weld toe's burr dressing, was studied. Both the post-weld heat treatment and the burr dressing produced a fatigue strength improvement. This fact is discussed, for both geometries, in the context of the initiation and propagation phases contribution to total fatigue life. Finally, several fatigue tests were performed under variable amplitude block loading using T6 post-weld heat-treated single lap joints, and the correspondent fatigue lives were compared with the predictions of Miner's rule.http://www.sciencedirect.com/science/article/B6V59-480CN2C-2/1/ef6815883b0431d9a8aa0d0d77743ff
