Abstract: objective: to explore students' assessments of the clinical seminar as a complementary teaching method to the clinical practicum experience. methods: this was a qualitative study based on the hermeneutic phenomenology of gadamer. twenty-three open-ended interviews were conducted from among the 132 first-year students who attended an initial clinical practicum. we performed a qualitative analysis of the data using atlas.ti software. results: the students agreed that the clinical seminar gave them the opportunity to learn about procedures, nursing care and interpersonal relationships. they also found it very helpful when they encountered challenging stressful situations as they performed their practice, and believed it allowed them to make a connection between the theory in the classroom and the clinical practice. conclusions: these seminars can contribute to reducing levels of stress during clinical practice. they can also help students obtain significant learning from their fellows and reduce the theory-practice gap.
Risk of African swine fever introduction into the European Union through transport-associated routes: returning trucks and waste from international ships and planes
Lina Mur, Beatriz Martínez-López, José Sánchez-Vizcaíno
BMC Veterinary Research , 2012, DOI: 10.1186/1746-6148-8-149
Abstract: Model results indicate that the relative risk for ASFV introduction through TAR in most of the EU countries (16) is low, although some countries, specifically Poland and Lithuania, concentrate high levels of risk, the returning trucks route being the analyzed TAR that currently poses the highest risk for ASFV introduction into the EU. The spatial distribution of the risk of ASFV introduction varies importantly between the analyzed introduction routes. Results also highlight the need to increase the awareness and precautions for ASF prevention, particularly ensuring truck disinfection, to minimize the potential risk of entrance into the EU.This study presents the first assessment of ASF introduction into the EU through TAR. The innovative model developed here could be used in data scarce situations for estimating the relative risk associated to each EU country. This simple methodology provides a rapid and easy to interpret results on risk that may be used for a target and cost-effective allocation of resources to prevent disease introduction.African swine fever (ASF) is one of the most devastating diseases of swine due to the high mortality caused (mainly in the hyper-acute and acute forms of the disease), the absence of effective vaccine, and the severe trade restrictions associated with its presence in the affected areas. ASF is caused by the infection of ASF virus (ASFV) which is transmitted by direct contact with fluids and excretions from infected animals. Blood, widely present in hyper-acute and acute forms of the disease, is considered the major route of direct transmission, containing high titers of virus for long lasting periods [1]. Other common ways of ASFV infection are the bites of infected ticks, and the indirect contact with various contaminated fomites and pig products, where ASFV remains infectious for long periods. As an example, ASFV infectivity persists more than 1000?days in frozen meat [2], 15?weeks in putrefied blood stored at room temperature

BMC Plant Biology , 2008, DOI: 10.1186/1471-2229-8-10
Abstract: RNA from pollen individually collected from 10 olive cultivars was used to amplify Ole e 1 sequences by RT-PCR, and the sequences were analyzed by using different bioinformatics tools. Numerous nucleotide substitutions were detected throughout the sequences, many of which resulted in amino acid substitutions in the deduced protein sequences. In most cases variability within a single variety was much lower than among varieties. Key amino acid changes in comparison with "canonical" sequences previously described in the literature included: a) the substitution of C19-relevant to the disulphide bond structure of the protein-, b) the presence of an additional N-glycosylation motif, and c) point substitutions affecting regions of Ole e 1 already described like relevant for the immunogenicity/allergenicity of the protein.Varietal origin of olive pollen is a major factor determining the diversity of Ole e 1 variants. We consider this information of capital importance for the optimal design of efficient and safe allergen formulations, and useful for the genetic engineering of modified forms of the allergen among other applications.Olive (Olea europaea L.) pollen produces respiratory allergy in the populations of geographical areas where this plant is widely cultivated, mainly the countries surrounding the Mediterranean Sea and several regions of North, South America and Australia [1,2]. Up to date, 10 allergens, i.e. Ole e 1 to Ole e 10, have been purified and characterized in Olea europaea L. pollen [3,4]. The major allergen Ole e 1 is a protein of 18–22 kDa, displaying acidic pI and different forms of N-glycosylation [5,6]. Besides its high homology to its counterparts in other members of the Oleaceae family, such as lilac and privet [7,8], Ole e 1 exhibits relevant similarity with the products of genes Lat52 from tomato, Zm13 from maize and several extensins from Arabidopsis thaliana and Nicotiana tabacum among other proteins. These proteins have been indexed like members

Abstract: Physical Education teachers have been using some very classic team sports, like football, basketball, handball, volleyball, etc. for many years in order to develop their education work at school. As a consequence of this, the benefits of this kind of activities on Physical Education lessons have not been as notable as we mighthave expected, since, even if they are increasing, their development and application are still low. There are many and very varied new non-traditional sports that have emerged and extended across Spain in recent years. To mention an example, we could refer to a newly created non-traditional sport such as kin-ball. This sport wascreated for the purpose of achieving a way to combine several factors such as health, team-work and competitiveness. Three teams of four players each participate. This way, every player can participate to a great extent in all the moves of the match, for each of them must defend one area of their half in order to achieve a common objective. Besides, kin-ball helps to develop motor skills at school in an easy way; that is, coordination, balance and perception. There is a large variety of non-traditional games and sports that are similar to kin-ball, such as floorball, intercrosse, mazaball, tchoukball, ultimate, indiaca, shuttleball... All of them show many physical, psychic and social advantages, and can help us to make the Physical Education teaching-learning process more motivating, acquiring the recreational component that it showed some years ago and which hasnow disappeared

Abstract: Static methods are a useful tool to analize the footprint, more simple and less expensive tran the dynamic methos to study the structure of the foot. Dynamic methods are often used to stydy foot′s funcionality. Through static methods we can provide a solution, among other problems like foot injuries, which could impact on future lower limb problems, or even to prescribe orthotics, etc. The aim of this study is to perform an analysis criteria for these methos of static analysis of the footprint. To conclude, static methos give more advanteges over the dynamics, however they could provide specific information
Effects of combined electrostimulation and plyometric training on vertical jump and speed tests
Journal of Human Sport and Exercise , 2011,
Abstract: The aim of this study was to determine the performance evolution of a group of athletes after 8 weeks of training that combined electrostimulation (NM ES) and plyometrics (PT). 78 medium level sprinter athletes participated, 40 women and 38 men (age, 15.9±1.4 years old, body mass index, 20.5±1.68 kg/m2; weight 58.53±8.05 kg; height, 1.68±0.07 m). The sample was randomized into four groups [Control (PT only), NM ES + PT, PT + NM ES, and Simultaneous (plyometric jumps were performed through the passage of current). Improvements were obtained in the Abalakov jump of 3.57% (p<0.01), 13.51% (p<0.001), 1.23% (p<0.01), and 0.77%, and in the sprint of 0.45%, 3.87% (p<0.05), 4.56% (p<0.01) and 7.26% p<0.001 for the control group, NM ES + PT group, PT + NM ES group, and Simultaneous group, respectively. It was concluded that a) improvement in vertical jump requires the application of the NM ES prior to PT; b) the sprinter athlete must combine the workout simultaneously or apply the ES after the PT training; and c) in sportspeople that require improvement in both the vertical jump and speed tests (e.g. basketball) the simultaneous method is not recommended, the order of application of NM ES and PT being non-determinant. Finally, the time needed to obtain significant improvement in strength training through a combination of NM ES and PT is substantially lower (15 days) than the time needed to improve speed (30 days).

Abstract: The purpose of this study was to examine the effects of eight- week (2 days/week) training periods of plyometric exercises (PT) and neuromuscular electrostimulation (EMS) on jump height in young athletes. Squat jump (SJ), counter movement jump (CMJ) and drop jump (DJ) were performed to assess the effects of the training protocols 98 athletes (100 & 200m and 100m & 110m hurdles) voluntarily took part in this study, 51 males (52%) and 47 females (48%), 17.91 ± 1.42 years old, and 5.16 ± 2.56 years of training experience. The participants were randomly assigned to four different groups according to the frequency and the timing of the stimulation. Analysis of covariance was used to analyze the effects of every training program on jump height. Our findings suggest that compared to control (Plyometrics (PT) only), the combination of 150Hz EMS + PT simultaneously combined in an 8 week (2days/week) training program, we could observe significant jump height improvements in the different types of strength: explosive, explosive-elastic, and explosive-elastic-reactive. The combination of PT after < 85 Hz EMS did not show any jump height significant increase in sprinters. In conclusion, an eight week training program (with just two days per week) of EMS combined with plyometric exercises has proven useful for the improvement of every kind of vertical jump ability required for sprint and hurdles disciplines in teenage athletes

Abstract: Resumen El propósito de este estudio fue diferenciar los niveles de grasa corporal de estudiantes de entre 13 y 15 a os, para a partir de ahí conocer las opiniones y actitudes que pueden asociarse con variables como la autoestima, hábitos sedentarios, la frecuencia de actividad física y salud, así como su relación respecto a variables independientes como la edad, sexo y composición corporal. El estudio fue realizado sobre 145 estudiantes de educación secundaria, divididos en dos grupos diferentes según el peso: el normal y sobrepeso. Se obtuvieron medidas de índice de masa corporal y bioimpedancia eléctrica, así como información adicional mediante un doble cuestionario. La validez y fiabilidad se calculó realizando análisis de datos exploratorio con factorización realizada sobre la matriz de correlaciones policórica, y el coeficiente alfa de Cronbach respectivamente. Se hallaron 3 factores que explican el 44% de la varianza. El análisis de resultados mediante ANOVA, expresó diferencias significativas de opinión (p < 0.05) entre sujetos sobrepeso y normopeso. Los primeros expresaron puntuaciones más bajas respecto a las recomendaciones recibidas del profesorado para realizar actividad física extraescolar, y consideraron que el ejercicio físico propuesto desde el Centro Educativo no es el más adecuado para combatir su exceso de peso corporal. Se evidenció una elevada indiferencia de los padres a la hora de recomendar la práctica deportiva a sus hijos con problemas de sobrepeso. Abstract This paper is intended to ascertain the body fat percentage of students between 13 and 15 years of age. Based on the former, the study researches opinions and attitudes which may be associated with variables like self-esteem, sedentary habits, frequency of physical activity and health, as well as the correlation between their answers and factors like age, sex and body composition. The study is based on evidence of 145 high school students divided into two groups: normal and overweight. Measurements of body mass index and electrical bioimpedance as well as additional information from a double questionnaire were obtained. Test validity and reliability was achieved using exploratory analysis and applying factorization on the polychoric correlation matrix and Cronbach's alpha. Three factors were found to explain 44% of the variance. Analysis of variance revealed significant differences between the opinion of normal and of overweight students (p < 0.05). The former scored lower than the latter as regards their teachers' recommendations about extra-curricular physical activity,

Abstract: We present the case of a male patient with post traumatic retroperitoneal fibrosis whose main clinical expression was low-back pain. Diagnosis was established using CAT-scan and MRI, which revealed a large mass of soft tissue that almost entirely enveloped the abdominal aorta. Treatment with 40 mg of prednisone every 24 hours was established. This dose was reduced gradually, and progressive remission of clinical signs and symptoms was achieved, with a significant improvement of subsequent imaging-test results. Treatment was continued for one year. Two and a half years later the patient remains symptom-free, with no recurrence of his condition. Se presenta el caso de un paciente varón afecto de una fibrosis retroperitoneal postraumática, a cuyo diagnóstico se llegó a partir de dolor lumbar como síntoma principal. El diagnóstico se efectuó en base a los estudios mediante CT y RM, los cuales demostraron una gran masa de tejido de partes blandas que rodeaban la aorta. El tratamiento consistió en dosis de prednisona que inicialmente se instauró a 40 mg cada 24 horas, y posteriormente se fue reduciendo de forma gradual hasta la remisión de los signos y síntomas, y consecuentemente de los estudios de imagen. El tratamiento con corticoides se mantuvo durante un a o. Dos a os y medio el paciente está libre de síntomas sin recidiva de su proceso.
