Incidencias de la conducta táctil como elemento no verbal de la comunicación en el aula : estudio de casos en la formación inicial del maestro especialista en educación física

Physical contact is a form of nonverbal communication also called tactile communication. It is an outstanding way to transmit messages of emotional or affective character in the first stages of life, but tends to disappear later due to the employment of other forms of communication and to the sexual connotations that it possesses. In this article we present a study of cases centered on the tactile communication of teachers in training in Physical Education during their practical classes. This behavior has been studied and analyzed through quantitative and qualitative techniques.
Work, narrative identity and social affiliation

Sociologists of work have been drawn into a conversation over work’s significance as a source of identity and social affiliation – ‘needs’ which, according to late modern theorists, are increasingly fulfilled in multiple other realms. This article enters this exchange by foregrounding the epistemological puzzle of how we can ‘know’ identity and social affiliation in narratives. As a provisional solution, Jenkins’s concepts of identification and categorization are brought into contact with Marks and Thompson’s emphasis on interests and identities and operationalized through Somers’s concepts of narrative identity, emplotment and categorization in an analysis of qualitative interviews with 52 working people and former workers in Canada.
Normal Postoperative Computed Tomography Findings after a Variety of Pancreatic Surgeries

Pancreatic surgery remains the only curative treatment for pancreatic neoplasms, and plays an important role in the management of medically intractable diseases. Since the original Whipple operation in the 20th century, surgical techniques have advanced, resulting in decreased postoperative complications and better clinical outcomes. Normal postoperative imaging findings vary greatly depending on the surgical technique used. Radiologists are required to be familiar with the normal postoperative imaging findings, in order to distinguish from postoperative complications or tumor recurrence. In this study, we briefly review a variety of surgical techniques for the pancreas, and present the normal postoperative computed tomography findings.
Development of circumference oscillation mechanism with adjustable amplitude

According to the situation of the currently developed circumference oscillation mechanism without adjustable amplitude generally. The circular oscillation mechanism with adjustable amplitude is designed. It mainly comprises an eccentric motion mechanism and adaptive dynamic balance mechanism. The dynamic simulation and analysis is carried out on eccentric motion mechanism. The experimental results show it can achieve 0-Φ50mm adjustable amplitude and 20-350RPM adjustable oscillation frequency in the meantime, and the latter can be realized by changing eccentricity adjusting pin manually. The unbalance quality of the table can be compensated by adaptive dynamic balance mechanism in order to increase the die life. Its amplitude can be changed simply, conveniently and fast, and has the characteristics of simple and compact mechanism, rigid connection, strong bearing capacity and maintenance easily. It will be widely used in the field of biological engineering.
Guidelines for handling parenteral antineoplastics.

To the Editor. — The article from the Council on Scientific Affairs 1 on handling parenteral antineoplastic agents was timely and well written. However, in discussing the risk of leukemia developing in patients with Hodgkin's disease who have been exposed to alkylating agents and procarbazine, a serious error was made in stating unequivocally that "these patients also received lymphoid irradiation. " In numerous studies, the incidence of acute nonlymphocytic leukemia after combined radiotherapy and chemotherapy for Hodgkin's disease has been no greater than that after chemotherapy alone. 2-5 Furthermore, reports of leukemia following radiotherapy alone are very rare. Clearly, the studies quoted above do not rule out a possible contribution to leukemogenesis by radiotherapy. However, such unqualified and erroneous statements as appeared in this article serve only to oversimplify a complex issue and, to some extent, misinform the many nononcologists who read your publication.
Finite Element Approach to Electric Field Distribution Resulting from Phase-sequence Orientation of a Double-Circuit High Voltage Transmission Line

This paper proposes a mathematical model of electric fields caused by high voltage conductors of electric power transmission systems by using a set of second-order partial differential equations. This study has considered the effect of conductor phase-sequence orientation on electric fields emitted around a doublecircuit, extra high-voltage, power transmission line. Six typical-used phase-sequence orientations in Thailand for 500-kV double-circuit transmission lines are investigated. Computer-based simulation utilizing the two dimensional finite element method in the time harmonic mode, instructed in MATLAB programming environment with graphical representation for electric field strength has been evaluated. The simulation results show that the phase-sequence orientation is one among key factors to influence the electric field distribution around the transmission line.

Needling therapies in the management of myofascial trigger point pain: a systematic review.

OBJECTIVE To establish whether there is evidence for or against the efficacy of needling as a treatment approach for myofascial trigger point pain. DATA SOURCES PubMed, Ovid MEDLINE, Ovid EMBASE, the Cochrane Library, AMED, and CISCOM databases, searched from inception to July 999. STUDY SELECTION Randomized, controlled trials in which some form of needling therapy was used to treat myofascial pain. DATA EXTRACTION Two reviewers independently extracted data concerning trial methods, quality, and outcomes. DATA SYNTHESIS Twenty-three papers were included. No trials were of sufficient quality or design to test the efficacy of any needling technique beyond placebo in the treatment of myofascial pain. Eight of the 10 trials comparing injection of different substances and all 7 higher quality trials found that the effect was independent of the injected substance. All 3 trials that compared dry needling with injection found no difference in effect. CONCLUSIONS Direct needling of myofascial trigger points appears to be an effective treatment, but the hypothesis that needling therapies have efficacy beyond placebo is neither supported nor refuted by the evidence from clinical trials. Any effect of these therapies is likely because of the needle or placebo rather than the injection of either saline or active drug. Controlled trials are needed to investigate whether needling has an effect beyond placebo on myofascial trigger point pain.
Alemtuzumab preconditioning allows steroid-calcineurin inhibitor-free regimen in live-donor kidney transplant.

OBJECTIVES This prospective study was designed to develop a steroid and calcineurin inhibitor-free regimen for kidney transplants using alemtuzumab. MATERIALS AND METHODS A single dose of alemtuzumab (30 mg) was given preoperatively. Phase 1: Twenty-one patients were randomized into 2 groups; the tacrolimus (n=11) and the sirolimus groups (n=10). Steroids were given for 5 days. Azathioprine (1 mg/kg) was added when white blood cells ≥ 4000 cells/cm(3). Mean follow-up was 48 ± 2.8 and 48.2 ± 1.6 months for the tacrolimus and sirolimus groups. Phase 2: Twenty patients were included and the study design was modified. Tacrolimus was given for 2 months, and was replaced by sirolimus thereafter. The mean follow-up was 28.3 ± 2.1 months. RESULTS Phase 1: Acute rejection episodes were encountered in 5 patients of the tacrolimus versus 2 cases in the sirolimus group (P = .44). Antibody-mediated rejection was diagnosed in 2 recipients in each group. Four patients were switched from sirolimus to tacrolimus owing to resistant rejection, significant proteinuria, persistent thrombocytopenia, lymphocele, and urinary leakage. One patient was shifted from tacrolimus to sirolimus owing to Kaposi sarcoma. Glomerular filtration rate was significantly higher in the sirolimus group. Currently, 14 patients (8 tacrolimus, and 6 sirolimus) are steroid-free. One patient died from the tacrolimus group owing to fulminant hepatitis. Two grafts were lost in the sirolimus group versus 1 graft in the tacrolimus group. Phase 2: Five patients developed successfully treated borderline changes with no antibody-mediated rejection. Mean serum creatinine was 114.9 ± 17.7 µmol/L. Currently, 17 patients are steroid free and 15 of them are calcineurin inhibitor-free as well. In this phase, only 1 patient died with a functioning graft. CONCLUSIONS This clinical trial provides a good insight into a potentially effective steroid and calcineurin inhibitor-free protocol with the use of alemtuzumab induction in combination with sirolimus.
Accelerating time‐resolved MRA with multiecho acquisition

A new four‐dimensional magnetic resonance angiograpy (MRA) technique called contrast‐enhanced angiography with multiecho and radial k‐space is introduced, which accelerates the acquisition using multiecho while maintaining a high spatial resolution and increasing the signal‐to‐noise ratio (SNR). An acceleration factor of approximately 2 is achieved without parallel imaging or undersampling by multiecho (i.e., echo‐planar imaging) acquisition. SNR is gained from (1) longer pulse repetition times, which allow more time for T1 regrowth; (2) decreased specific absorption rate, which allows use of flip angles that maximize contrast at high field; and (3) minimized effects of a transient contrast bolus signal with a shorter temporal footprint. Simulations, phantom studies, and in vivo scans were performed. Contrast‐enhanced angiography with multiecho and radial k‐space can be combined with parallel imaging techniques such as Generalized Autocalibrating Partially Parallel Acquisitions (GRAPPA) to provide additional 2‐fold acceleration in addition to higher SNR to trade off for parallel imaging. This technique can be useful in diagnosing vascular lesions where accurate dynamic information is necessary. Magn Reson Med 63:1520–1528, 2010. © 2010 Wiley‐Liss, Inc.
Neural-PSO second order sliding mode controller for unknown discrete-time nonlinear systems

This paper deals with adaptive tracking for unknown discrete-time MIMO nonlinear systems in presence of disturbances. A Particle Swarm Optimization (PSO) is used to improve a discrete-time neural second order sliding mode controller for unknown discrete-time nonlinear systems. In order to show the applicability of the proposed scheme, simulation results are included for a Van der Pol oscillator.
Designing Efficient Algorithms for the Eventually Perfect Failure Detector Class

This paper focuses on the design of unreliable failure detectors of the Eventually Perfect class (◊P) in crash-prone partially synchronous systems. We adopt a monitoring mechanism based on heartbeats over a logical ring arrangement of processes as the common design feature. This provides good communication efficiency, a performance parameter which refers to the number of links that carry messages forever. We follow two different approaches that result in two families of failure detectors: a nearly communication-efficient family, which uses n + C links forever, being C the number of correct processes out of the n processes in the system, and a communication efficient family, which uses only n links forever. Besides communication efficiency, we evaluate the algorithms in terms of QoS parameters, which include the capability of the failure detector to provide right answers as well as its reaction time.
Prior anti-thrombotic drugs and stroke mortality

The very interesting and provocative paper by Kwok et al 1 raises some important questions that have significant implications in terms of the clinical management of patients with haemorrhagic strokes. The Kwok study examined more than 3300 patients in the UK who were hospitalised with either an ischaemic stroke or a haemorrhagic stroke (intracerebral haemorrhage (ICH) only; patients with a subarachnoid haemorrhage were excluded). Almost half of the patients (47%) were taking either an antiplatelet agent or an anticoagulant. A key finding of this study was that for patients with an ischaemic stroke, the use of either antiplatelet agents or anticoagulants did not impact mortality subsequent to the stroke, looking at intervals ranging from 7 days to 365 days post-ischaemic stroke. The results for patients admitted with a haemorrhagic stroke were quite different, with higher mortality rates for patients taking an antiplatelet agent or anticoagulant among this group. A closer examination of the results shows that much of the difference in outcomes was driven by the higher mortality associated with prior anticoagulant use, with ORs of 2.0 to 2.8 for most models related to anticoagulant use, compared to ORs of 1.5 to 1.8 for antiplatelet use. Another curious finding is that most of the excess mortality occurred in a bi-modal pattern, with higher morality being seen early (0–30 days) and late (90–365 days) post-stroke. In a related manner, and a significant limitation of this study, is that the actual cause of death was not recorded, due largely to the administrative …
Phylogenetic Incongruence among Oncogenic Genital Alpha Human Papillomaviruses

ABSTRACT The human papillomaviruses (HPVs) have long been thought to follow a monophyletic pattern of evolution with little if any evidence for recombination between genomes. On the basis of this model, both oncogenicity and tissue tropism appear to have evolved once. Still, no systematic statistical analyses have shown whether monophyly is the rule across all HPV open reading frames (ORFs). We conducted a taxonomic analysis of 59 mucosal/genital HPVs using whole-genome and sliding-window similarity measures; maximum-parsimony, neighbor-joining, and Bayesian phylogenetic analyses; and localized incongruence length difference (LILD) analyses. The algorithm for the LILD analyses localized incongruence by calculating the tree length differences between constrained and unconstrained nodes in a total-evidence tree across all HPV ORFs. The process allows statistical evaluation of every ORF/node pair in the total-evidence tree. The most significant incongruence was observed at the putative high-risk (i.e., cancer-associated) node, the common oncogenic ancestor for alpha HPV species 9 (e.g., HPV type 16 [HPV16]), 11, 7 (e.g., HPV18), 5, and 6. Although these groups share early-gene homology, including high degrees of similarity among E6 and E7, groups 9 and 11 diverge from groups 7, 5, and 6 with respect to L2 and L1. The HPV species groups primarily associated with cervical and anogenital cancers appear to follow two distinct evolutionary paths, one conferred by the early genes and another by the late genes. The incongruence in the genital HPV phylogeny could have occurred from an early recombination event, an ecological niche change, and/or asymmetric genome convergence driven by intense selection. These data indicate that the phylogeny of the oncogenic HPVs is complex and that their evolution may not be monophyletic across all genes.
Statins and Intracerebral Hemorrhage: Collaborative Systematic Review and Meta-Analysis

Background— A recent large, randomized trial suggested that statins may increase the risk of intracerebral hemorrhage. Accordingly, we systematically reviewed the association of statins with intracerebral hemorrhage in randomized and observational data. Methods and Results— We screened 17 electronic bibliographic databases to identify eligible studies and consulted with experts in the field. We used DerSimonian-Laird random-effects models to compute summary risk ratios with 95% confidence intervals. Randomized trials, cohort studies, and case-control studies were analyzed separately. Only adjusted risk estimates were used for pooling observational data. We included published and unpublished data from 23 randomized trials and 19 observational studies. The complete data set comprised 248 391 patients and 14 784 intracerebral hemorrhages. Statins were not associated with an increased risk of intracerebral hemorrhage in randomized trials (risk ratio, 1.10; 95% confidence interval, 0.86–1.41), cohort studies (risk ratio, 0.94; 95% confidence interval, 0.81–1.10), or case-control studies (risk ratio, 0.60; 95% confidence interval, 0.41–0.88). Substantial statistical heterogeneity was evident for the case-control studies (I2=66%, P=0.01), but not for the cohort studies (I2=0%, P=0.48) or randomized trials (I2=30%, P=0.09). Sensitivity analyses by study design features, patient characteristics, or magnitude of cholesterol lowering did not materially alter the results. Conclusions— We found no evidence that statins were associated with intracerebral hemorrhage; if such a risk is present, its absolute magnitude is likely to be small and outweighed by the other cardiovascular benefits of these drugs.
Consideración del factor Percepción Visual en material bibliográfico sobre "Movilidad Urbana para una Planificación Sostenible"

Pesquisa, analisis y reflexion sobre los topicos manejados en la postulacion y discusion acerca de la movilidad urbana sostenible, que aluden o consideran explicita o implicitamente en algun grado la incidencia del factor Percepcion Visual. El estudio se circunscribe a los postulados, estrategias, instrumentos, normativas, ejemplos y sugerencias proporcionados como bibliografia basica y complementaria al curso "Movilidad y Planeamiento Sostenible". Para su revision se elige el enfoque de la Percepcion Visual (PV), dada la necesidad que tiene la filosofia de la sostenibilidad de concluir en 'artes' concretas, dispositivos, senaleticas y demas artilugios que deben ser captados a distancia, para finalmente inducir conductas y comportamientos. De no ser asi, no se alcanzarian resultados esperados. Este enfoque se aplica, primero, bajo la hipotesis de que la PV , no obstante ser un filtro que se apropia personalizadamente de la realidad, se apoya en mecanismos comunes a la especie pero tambien culturales que responden y son centralmente activados y condicionados por atributos especificos de los estimulos o por condiciones de su contexto, lo que hace que el fenomeno de la PV en sus rasgos y efectos globales estructurales , pueda ser anticipado o vaticinado. En segundo lugar, suponiendo que la PV, por ser un fenomeno activo - que 'construye la realidad' en el circuito de las significaciones e 'ideas significativas'- es una experiencia que tanto promueve como inhibe conductas y comportamientos determinados. Para el efecto, luego de una puesta en comun de los aspectos de la PV que se estiman a priori como incidentes a la escala urbana y a objeto de explicitar el alcance y profundidad que nos ocupa, nos abocamos a constatar la existencia de rasgos inductores, reforzadores o facilitadores de la percepcion visual o bien que son disuasivos, distractores, ambiguadores o entorpecedores, perceptuales , deduciendo sus efectos y posibles factores que los explican.
Epidemiology of association between maternal periodontal disease and adverse pregnancy outcomes--systematic review.

BACKGROUND AND OBJECTIVES There is still debate regarding potential relationships between maternal periodontitis during pregnancy and adverse pregnancy outcomes. The aim of this systematic review was to synthesize the available epidemiological evidence on this association. DATA SOURCES Combined electronic and hand search of MEDLINE, EMBASE, WEB OF SCIENCE and Cochrane Central Register databases. STUDY ELIGIBILITY CRITERIA Original publications reporting data from cross-sectional, case-control or prospective cohort epidemiological studies on the association between periodontal status and preterm birth, low birthweight (LBW) or pre-eclampsia. The search was not limited to publications in English. All selected studies provided data based on professional assessments of periodontal status, and outcome variables, including preterm birth (<37 weeks gestation), LBW (<2500 g), gestational age, small for gestational age, birthweight, pregnancy loss or miscarriage, or pre-eclampsia. PARTICIPANTS Pregnant women with or without periodontal disease, and with or without adverse pregnancy outcomes, assessed either during pregnancy or postpartum. No intervention studies were included. Study appraisal and synthesis methods - Publications were assessed based on predefined screening criteria including type of periodontal assessment, consistency in the timing of the periodontal assessment with respect to gestational age, examiner masking and consideration of additional exposures and confounders. RESULTS Maternal periodontitis is modestly but significantly associated with LBW and preterm birth, but the use of a categorical or a continuous exposure definition of periodontitis appears to impact the findings: Although significant associations emerge from case-control and cross-sectional studies using periodontitis "case definitions," these were substantially attenuated in studies assessing periodontitis as a continuous variable. Data from prospective studies followed a similar pattern, but associations were generally weaker. Maternal periodontitis was significantly associated with pre-eclampsia. LIMITATIONS There is a high degree of variability in study populations, recruitment and assessment, as well as differences in how data are recorded and handled. As a result, studies included in meta-analyses show a high degree of heterogeneity. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS Maternal periodontitis is modestly but independently associated with adverse pregnancy outcomes, but the findings are impacted by periodontitis case definitions. It is suggested that future studies employ both continuous and categorical assessments of periodontal status. Further use of the composite outcome preterm LBW is not encouraged.
Estudio Psicométrico y Predicción de la Importancia de la Educación Física a Partir de las Orientaciones de Meta (“ Perception of Success Questionnaire - POSQ”)

The present research has two main goals: (a) to analyze psychometric properties of the Perception of Success Questionnaire (POSQ) adapted to Physical Education (PE), and (b) to analyze the prediction of importance and usefulness granted to PE from goal orientations, perceived competence and student satisfaction. The questionnaire consisted of the following instruments: POSQ, Basic Psychological Needs in Exercise Scale, Satisfaction with PE and the Importance of PE. They were administered to 846 Spanish high school students aged 12 to 19 years. POSQ structure was analyzed by confirmatory procedures and it showed reliable internal consistency and a stable factor structure which supports the hypothesized theoretical model: ego and task orientation. Thus, it is considered a valid instrument to measure dispositional goal orientation in PE. For predicting the importance of PE from goal orientations, competence and satisfaction, it was used a structural equation model which confirmed that task orientation is the most influential on perceived competence, and the latter in satisfaction/fun. Fact that predicts the students consider the subject more important and useful.
