Patent foramen ovale screening by ear oximetry in divers

The aim of this study was to test the hypothesis that ear oximetry immediately after the release of a sustained Valsalva maneuver accurately detects patent foramen ovale (PFO). One hundred sixty-five scuba divers underwent transesophageal echocardiography (TEE; reference method) for PFO assessment. Ear oximetry of the right earlobe was performed in a different room within a time frame of 2 hours before or after TEE. The subject and the oximetry operator were unaware of the results of TEE. Oxygen saturation (SO(2)) measurements were obtained at baseline and during the release phase of 4 Valsalva maneuvers within 10 minutes, and the average SO(2) change (SO(2) at baseline minus SO(2) at Valsalva release) was determined as the primary study end point. One hundred seventeen divers had no PFO, and 48 (29%) had PFO by TEE (mean age 39 ± 8 years). The average SO(2) change was 0.79 ± 1.13% (i.e., a slight absolute SO(2) decrease in response to the Valsalva maneuver) in the group without PFO and 1.67 ± 1.19% in the PFO group (p <0.0001). Using receiver-operating characteristic curve analysis, a PFO as defined by TEE could be detected at a threshold of a Valsalva-induced decrease in SO(2) of ≥0.825 percentage points in comparison to baseline (sensitivity 0.756, specificity 0.706, area under the receiver-operating characteristic curve 0.763, p <0.0001, negative predictive value 0.882). In conclusion, the entirely noninvasive method of ear oximetry in response to repetitive Valsalva maneuvers is accurate and useful as a screening method for the detection of a PFO, as shown in this study of divers.

Manifesta och latenta ideologier om lärande inom svensk spelmansrörelse under 1920-talet

The purpose of this article was to illuminate existing educational ideologies in the Swedish fiddler movement (Spelmansrörelsen) 1923-1927. This period was characterized by the organization and to some extent institutionalization of Swedish folk music. Furthermore, the purpose was to discuss the results in relation to the folk music education of today. The empirical data was taken from the journal Hembygden, which was a magazine for scholars, enthusiasts and practitioners of folk music. Theoretically, the study was based on a concept of ideology developed by Sven-Eric Liedman: in every time there are two basic forms of identifiable ideology, manifest and latent. From the empirical material as a whole (around 900 articles), a selection was made to find articles dealing with aspects of learning among the fiddlers (33 articles). After content analysis the following themes were generated: Fiddlers’ repertoire, Fiddlers’ masters, Rooms for learning, Learning formation. The writers in Hembygden often emphasized the autodidactic aspects of learning and especially the importance of learning by ear. This manifest ideology of authenticity presumed that learning directly from another fiddler by playing together was to prefer to formal schooling. In spite of a tendency towards more ensemble playing, the folk music education of today in Sweden is characterized by a similar retrospective ideology as in the 1920s.

From the beginning, the world of game-playing by machine has been fortunate in attracting contributions from the leading names of computer science. Charles Babbage, Konrad Zuse, Claude Shannon, Alan Turing, John von Neumann, John McCarthy, Alan Newell, Herb Simon and Ken Thompson all come to mind, and each reader will wish to add to this list. Recently, the Journal has saluted both Claude Shannon and Herb Simon. Ken’s retirement from Lucent Technologies’ Bell Labs to the start-up Entrisphere is also a good moment for reflection.

Análise das manifestações auditivas em individuos com hipertensão arterial sistêmica

Objective: To determine the prevalence of auditory manifestations in individuals with hypertension and analyze the association between hearing loss, systemic hypertension and quality of life in hypertensive patients. Method: This was a prospective, observational, case-control study, carried out from June 2010 to December 2013 at the University Hospital Onofre Lopes, in Natal, Brazil, which involved 120 patients of both sexes were analyzed with a diagnosis of hypertension and 120 patients without a diagnosis of hypertension. The audiological function was assessed by tonal and vocal audiometry. The quality of life was defines by the MINICHAL BRASIL questionnaire. Results: The prevalence of hearing loss was high in both groups (82.5 % and 75.8 %, in hypertension group and control, respectively, p=0.003). The sensorineural was the most common type of hearing loss (48.5 %) in hypertension group while conductive hearing loss was predominant (61.5 %) in the control group. There were no difference in the intensity of hearing loss between the groups (p=0,21). The main hearing complaint was hearing loss (51 %), followed by ear pain (14 %). There was worse quality of life in hypertensive individuals with hearing loss (p= 0.0001). Conclusion: Hypertensive individuals showed higher prevalence of auditory events, including hearing loss, sensorineural hearing loss is predominant . Hearing loss is associated with worse quality of life of hypertensive individuals even when these pressure values are within normal limits

Desempenho agronômico de híbridos de milho, em função da aplicação foliar de fungicidas

The objective of the study was to evaluate the agronomic performance of corn hybrids (AG 8088, BG 7049, CD 327, CD 384, CD 351 and CD 321) at function of the foliar application of two fungicides (piraclostrobina + epoxiconazol and azoxistrobina + ciproconazol) at pre-tasseling of the culture. The experiment was conducted In Selviria - MS, in the experimental Farm of the Faculty of Engineering of Ilha Solteira - SP (UNESP), Brazil, during the harvest of 2008/09. The treatments were disposed in randomized complete block design in a factorial scheme 6 x 3 (corn hybrids x fungicides), with four replications. There was valued plant height and of insertion of the ear, number of rows of grains by ear and of grains by row, incidence of foliar diseases, weight of hundred grains and productivity. The results were submitted to the analysis of variance, and the hybrids and fungicides compared by Tukey test (P<0.05). For data analysis were used the software SISVAR. The foliar application of the fungicides piraclostrobina + epoxiconazol and azoxistrobina + ciproconazol in pre-tasseling of the culture the corn reduced the incidence of foliar diseases, nevertheless, was not sufficient to provoke growth of productivity. The hybrids CD 321, AG 8088 and CD 351 were highlighted by the higher yield obtained.

Sinais e sintomas na Síndrome de Costen associada a desordens temporomandibulares: relato de caso clínico

Costen’s syndrome is defined as a set of auditory signs and symptoms in patients with TMD. It is characterized by ear fullness, hearing loss, tinnitus, ear pain and vertigo with nystagmus.It has predilection for females and fourth decade of life. The multidisciplinary monitoring of these patients is imperative in its recognition and the establishment of effective therapy. In this paper we report a case of Costen’s Syndrome patient whose treatment consisted of advice on the etiology of the disorder and weekly sessions of acupuncture. The clinical features that led to the diagnosis and treatment plan, and the effectiveness of acupuncture as supportive therapy were also discussed.

Fronteras sociales de la Odisea

La relación entre pretendientes, nobles y servidores resulta muy compleja en Odisea. Dentro del expandido mundo doméstico que el poema presenta no se halla una respuesta clara para la presencia de los pretendientes, como tampoco para el rol social desempeñado por algunos servidores cuya característica definitoria es haber sido nobles y expresar en la actualidad una prueba fehaciente de las variaciones de la fortuna. Tal es el caso de Euriclea y Eumeo. El trabajo propone la discusión de la elaboración de los límites entre una clase social y otra, así como la constitución de las fronteras entre ellas, para interpretar la forma en que se articulan en el poema la situación social de personajes menores con la adhesión al héroe protagonista.

European regions in Brussels: towards functional interest representation? Bruges Political Research Papers 53/2016

Opportunities structures for participation in EU policy-making are characterised by the inefficiency of institutional channels of territorial representation and the progressive inclusion of broad civil society in new systems of consultation and cooperation with EU institutions. Recent Multilevel Governance literature has recognised an increasing convergence in strategies of territorial and functional actors to respond to these challenges. Nevertheless, it has neglected the partial shift of European regions from territorial institutional representation to lobbying strategies based on acting as intermediaries for functional interests. Through strong cooperation with the private sector, regions go beyond their purely institutional roles, partly presenting themselves as actors of functional representation and thus playing by the same rules of most lobbying actors in Brussels: providing specialised and genuine information to EU institutions in exchange for inclusion in the policy-making process.

A INSTITUIÇÃO ESCOLAR ESPECIAL E SEUS CONFLITOS ESTUDO DE CASO

O presente estudo realiza uma análise dos conflitos entre profissionais especialistas na organização escolar especial privada, segundo a percepção e análise dos registros da pesquisadora como docente e coordenadora na área de Educação Especial. Há algum tempo, a organização escolar especial é composta de diversos especialistas para atender às necessidades dos seus alunos. Tais profissionais possuem formações e desempenho de papéis distintos que são combustíveis para conflitos. A pesquisa trata do assunto por meio das teorias: clássica, das relações humanas e teoria estruturalista, da sociologia e psicologia das organizações. Por meio da união dos registros da experiência vivida pela pesquisadora com os estudos bibliográficos confirmou as hipóteses de que os conflitos na organização escolar especial ocorrem por disputa, por legitimidade, por desempenho de papéis, pelas especialidades e por mudanças.

Causes of tension in post-observation feedback in pre-service teacher training: an alternative view

A central component in pre-service teacher training is teaching practice and feedback. In some cases, feedback results in disquiet and tension (Brandt, 2008). Many researchers attribute this tension to the incompatibility of the assessment and development roles that the trainer must perform. The research reported on here, however, suggests that tension may also be rooted in a difference in expectation amongst trainers and trainees about the purpose and performance of feedback. This can result in trainees not playing by the rules of the game (Roberts & Sarangi, 2001) either because they do not understand them or because they wish to challenge them.
