Empatia y ecualización en estudiantes de odontología en una universidad chilena / Empathy and equalization in dentistry students at a chilean university

RESUMEN Objetivo: Verificar el cumplimiento del principio de ecualización de la empatía con el paciente en los estudiantes de la Facultad Odontología de dos sedes de la Universidad Andrés Bello: República (Región Metropolitana) y Viña del Mar (Quinta Región), Chile. Materiales y métodos: Se empleó la Escala de Empatía Médica de Jefferson (versión S) adaptada por criterio de jueces para estudiantes de odontología. Se estimaron las medias, error estándar de las medias y el intervalo de confianza de los datos en torno de la media dentro y entre de los tres factores estudiados: Sedes, Curso y Sexo y sus interacciones. Se compararon las medias de los niveles mediante un análisis de varianza trifactorial. Se estimó la prueba eta cuadrada y la potencia de la prueba para determinar la magnitud de las diferencias y la potencia del modelo estadístico empleado. El nivel de significación utilizado fue de α<0,05 y ß<0,20. Resultados: Se encontraron pocas diferencias significativas entre las medias. Las diferencias fundamentales afectaron principalmente a una de las dimensiones cognitivas de la empatía: "Habilidad para entender a otros". Aunque la simetría de los niveles de los factores y sus interacciones no afectan totalmente la similaridad del comportamiento empático entre las sedes de la universidad estudiada, la presencia de diferencias muestra la necesidad de prestar más atención a la formación empática en los estudiantes de odontología. Conclusiones: Es necesario considerar estas diferencias encontradas entre las sedes para analizar las causas que las producen y realizar las intervenciones pertinentes para disminuir estas diferencias.

SUMMARY Introduction: Verify compliance with the principle of equalization of empathy in two locations or campus of Universidad Andrés Bello, Chile. Material and methods: The Jefferson Medical Empathy Scale (version S) was used, adapted by the criteria of Judges for Dentistry students. The means, standard error of the means and the confidence interval of the data around the mean within and between the three factors studied were estimated: Campus, Course, and Sex and their interactions. The means of the levels were compared by means of a Three-factor Analysis of Variance. The eta squared test and the power of the test were estimated to determine the magnitude of the differences and the power of the statistical model used. The significance level used was α <0.05 and ß<0.20. Results. Few significant differences were found between the means. The fundamental differences mainly affected one of the cognitive dimensions of empathy: "Ability to understand others". Although the symmetry of the levels of the factors and their interactions do not totally affect the similarity of empathic behavior between the campus of the university studied, the presence of differences shows the need to pay more attention to empathic training in dental students. Conclusions. It is necessary to consider these differences found between the venues to analyze the causes that produce them and carry out the pertinent interventions to reduce these differences.

Do men and women have different musculoskeletal symptoms at the same musculoskeletal discomfort level?

Owing to biological and social factors, illness-related musculoskeletal symptoms tend to vary between men and women. However, in the past, conceptualised discomfort metrics were applied uniformly to both genders. This study aimed to develop a scale to measure musculoskeletal discomfort that compares the symptoms between men and women. The scale aimed to determine the gender-based response patterns related to symptoms. A total of 707 men and 1302 women reported their symptoms on a body map. Factor analysis and item response theory were used to differentiate the identified symptoms in the construction of a musculoskeletal discomfort scale. Differences in work exposure appeared to explain the symptom patterns between men and women. The scale had eight levels, and it was found that at the same level of discomfort, men and women reported symptoms in different body regions.Practitioner summary: On this discomfort scale, the response patterns of men and women were categorised into eight levels. Symptoms differed by gender at the same musculoskeletal discomfort level. This is in contrast to previous studies in which scales were devised without considering differences between the genders.Abbreviations: WMSDs: work-related musculoskeletal disorders; BMI: body mass index; FA: factor analysis; IRT: item response theory; KMO: Kaiser-Meyer-Olkin; BST: Bartlett's test of sphericity; F: factor loading; h2: communality; α: Cronbach's alpha; ωt: McDonald's omega; ai: parameters of discrimination of the items; bik: parameters of difficulty of response categories; θj: latent trait; RMSEA: root mean square error of approximation; CFI: comparative fit index; TLI: Tucker-Lewis index; odu: musculoskeletal discomfort units; RA: rarely; OF: often; AL: always.

Convolutional Neural Networks Using Enhanced Radiographs for Real-Time Detection of Sitophilus zeamais in Maize Grain.

The application of artificial intelligence (AI) such as deep learning in the quality control of grains has the potential to assist analysts in decision making and improving procedures. Advanced technologies based on X-ray imaging provide markedly easier ways to control insect infestation of stored products, regardless of whether the quality features are visible on the surface of the grains. Here, we applied contrast enhancement algorithms based on peripheral equalization and calcification emphasis on X-ray images to improve the detection of Sitophilus zeamais in maize grains. In addition, we proposed an approach based on convolutional neural networks (CNNs) to identity non-infested and infested classes using three different architectures; (i) Inception-ResNet-v2, (ii) Xception and (iii) MobileNetV2. In general, the prediction models developed based on the MobileNetV2 and Xception architectures achieved higher accuracy (≥0.88) in identifying non-infested grains and grains infested by maize weevil, with a correct classification from 0.78 to 1.00 for validation and test sets. Hence, the proposed approach using enhanced radiographs has the potential to provide precise control of Sitophilus zeamais for safe human consumption of maize grains. The proposed method can automatically recognize food contaminated with hidden storage pests without manual features, which makes it more reliable for grain inspection.

Joint pre-processing framework for two-dimensional gel electrophoresis images based on nonlinear filtering, background correction and normalization techniques.

BACKGROUND: Two-dimensional gel electrophoresis (2-DGE) is a commonly used tool for proteomic analysis. This gel-based technique separates proteins in a sample according to their isoelectric point and molecular weight. 2-DGE images often present anomalies due to the acquisition process, such as: diffuse and overlapping spots, and background noise. This study proposes a joint pre-processing framework that combines the capabilities of nonlinear filtering, background correction and image normalization techniques for pre-processing 2-DGE images. Among the most important, joint nonlinear diffusion filtering, adaptive piecewise histogram equalization and multilevel thresholding were evaluated using both synthetic data and real 2-DGE images. RESULTS: An improvement of up to 46% in spot detection efficiency was achieved for synthetic data using the proposed framework compared to implementing a single technique of either normalization, background correction or filtering. Additionally, the proposed framework increased the detection of low abundance spots by 20% for synthetic data compared to a normalization technique, and increased the background estimation by 67% compared to a background correction technique. In terms of real data, the joint pre-processing framework reduced the false positives up to 93%. CONCLUSIONS: The proposed joint pre-processing framework outperforms results achieved with a single approach. The best structure was obtained with the ordered combination of adaptive piecewise histogram equalization for image normalization, geometric nonlinear diffusion (GNDF) for filtering, and multilevel thresholding for background correction.

Ecualización de la empatía en estudiantes de dos sedes diferentes en una facultad de odontología de una universidad chilena / Empathy equalization in students from two different campus in a chilean faculty of dentistry

Objetivo. Comprobar que el proceso de ecualización para el atributo empatía se cumple entre dos sedes universitarias en los estudiantes de odontología de la Universidad San Sebastián (Chile). Material y Métodos. Se aplicó la Escala de Empatía Médica de Jefferson para medir la empatía y sus componentes en estudiantes de odontología de la Universidad San Sebastián en dos sedes (Santiago y Concepción, Chile). Las comparaciones se realizaron mediante un ANOVA Bifactorial (Modelo III), estimación del potencial de crecimiento posible y ecuaciones de regresión. Resultados. Se encontró que existen diferencias para el componente TPP entre las sedes y diferencias entre todos los componentes de la empatía cuando fueron comparados un mismo género entre sedes. Conclusión. La evidencia empírica muestra que el proceso de ecualización no se encuentra completado. Este estudio tiene importancia nacional y a nivel de América Latina por tres razones: a) muchas universidades en Chile y América Latina tienen sedes universitarias donde se imparten la misma carrera de pregrados, b) no existen evaluaciones de ecualización de la empatía en América Latina y c) se plantea una posible metodología para evaluar el cumplimiento de la ecualización.

Objective. Check that the equalization process for the empathy attribute is fulfilled between two university venues in the dentistry students of the San Sebastián University (Chile). Material and methods. The Jefferson Medical Empathy Scale was applied to measure empathy and its components in dental students of the San Sebastián University in two sites (Santiago and Concepción, Chile). The comparisons were made using a Bifactorial ANOVA (Model III), estimation of the possible growth potential and regression equations. Results. It was found that there are differences for the Taking Patient's Perspective component between the venues and differences between all the components of the empathy when the same genre was compared between venues. Conclusion. Empirical evidence shows that the equalization process is not complete. This study is of national and Latin American importance for three reasons: a) many universities in Chile and Latin America have university campuses where the same undergraduate courses are taught, b) there are no equalization evaluations of empathy in Latin America, and c) a possible methodology is proposed to evaluate the compliance of the equalization.

Variation in Use of Tympanostomy Tubes: Impact of Privately Owned Ambulatory Surgery Centers.

OBJECTIVE: To determine whether privately owned ambulatory surgery centers (ASCs) increase pediatric tympanostomy tube use in their surrounding communities. STUDY DESIGN: We studied children <5 years of age who underwent outpatient tympanostomy tube placement in New York or Florida in 2010-2014. Data came from the Healthcare Cost and Utilization Project State Ambulatory Surgery Databases, which include all outpatient surgeries in these states. Population characteristics came from the US Census' American Community Survey. Weighted conditionally autoregressive models were used to assess the association between the zip code-level proportion of tympanostomy tube procedures performed in privately owned ASCs and the rate of tympanostomy tube use. RESULTS: In 2010-2014, 106 privately owned ASCs in Florida and 29 in New York performed tympanostomy tube placement in young children. After accounting for zip code-level urban/rural status, socioeconomic status (SES), and the proportion of residents of non-Hispanic white race, children residing in zip codes in the top tertile of privately owned ASC use in Florida had 52% greater tympanostomy tube use than children from zip codes in the bottom tertile (P < .001). In New York, high-SES zip codes with any use of privately owned ASCs had 2.6 times greater tympanostomy tube use than other high-SES zip codes (P < .001). This association was not present in low-SES areas. CONCLUSIONS: The presence of privately owned ASCs is associated with increased tympanostomy tube use in young children.

A deeper mining on the protein composition of VA-MENGOC-BC®: An OMV-based vaccine against N. meningitidis serogroup B and C.

The protein composition of an Outer Membrane Vesicle (OMV) preparation that constitutes the active pharmaceutical ingredient of VA-MENGOC-BC®, an effective vaccine against Neisseria meningitidis serogroups B, and C is presented. This preparation has a high lipid content and five abundant membrane proteins (FetA, PorA, PorB, RmpM, and Opc), constituting approximately 70% of the total protein mass. The protein composition was determined by combining the use of the Hexapeptide Ligand Library and an orthogonal tandem fractionation of tryptic peptides by reverse-phase chromatography at alkaline and acid pH. This approach equalizes the concentration of tryptic peptides derived from low- and high-abundance proteins as well as considerably simplifying the number of peptides analyzed by LC-MS/MS, enhancing the possibility of identifying low-abundance species. Fifty-one percent of the proteins originally annotated as membrane proteins in the genome of the MC58 strain were identified. One hundred and sixty-eight low-abundance cytosolic proteins presumably occluded within OMV were also identified. Four (NadA, NUbp, GNA2091, and fHbp), out of the five antigens constituting the Bexsero® vaccine, were detected in this OMV preparation. In particular, fHbp is also the active principle of the Trumenba® vaccine developed by Pfizer. The HpuA and HpuB gene products (not annotated in the MC58 genome) were identified in the CU385 strain, a clinical isolate that is used to produce this OMV. Considering the proteins identified here and previous work done by our group, the protein catalogue of this OMV preparation was extended to 266 different protein species.

Aplicación del mainstreaming de género en las organizaciones a través de las certificaciones / Implementation of gender mainstreaming in organizations through certifications

Las desigualdades entre mujeres y hombres se siguen manteniendo en las organizaciones a pesar de los esfuerzos políticos y sociales realizados para afrontar este fenómeno. Las certificaciones de igualdad son reconocidas en España como uno de los instrumentos políticos diseñados para combatir estos desequilibrios de género a partir de la promulgación de la Ley Orgánica nº 3/2007 para la igualdad efectiva de mujeres y hombres. Este artículo tiene como objetivo identificar el enfoque desde el que las organizaciones, públicas y privadas, responsables de la promoción de certificaciones de igualdad de género, están respondiendo a la aplicación del mainstreaming de género. Aplicamos un análisis de contenido a partir del estudio de publicaciones relativas a las certificaciones. Los resultados muestran que estas certificaciones se conceden, en muchos casos, ignorando indicadores esenciales para implementar el enfoque de género. Igualmente, se impulsa su uso lucrativo como marca de calidad organizativa.

Inequalities between women and men persist in organizations in spite of political and social efforts to fight this phenomenon. Gender equality certifications have been recognized in Spain as one of the political measures aimed at combating gender imbalances since the promulgation of the organic Law nº 3/2007 on effective equality of women and men. This article aims to identify the approaches adopted by public and private organizations that are responsible to promote gender equality certifications in response to gender mainstreaming implementation. Content analysis of publications related to gender certifications was carried out. The results show that in many cases these certifications are granted disregarding essential indicators to implement the gender mainstreaming approach. Similarly, they have been used to boost profit since it indicates a distinguishing quality of these organizations.

Implementación de un sistema de imagenología infrarroja para la detección vascular del antebrazo y mano / Implementation of an infrared imaging system for vascular detection in the forearm and hand

RESUMEN: En el área clínica son procedimientos comunes la venopunción, la colocación de catéteres, inyecciones intravenosas, etc. La visualización de las venas en algunas personas es compleja. En este trabajo se presenta el desarrollo de un sistema capaz de realzar la distribución de las venas en el antebrazo de una persona para, en un trabajo futuro, ayudar de forma no invasiva a localizar las venas en los procedimientos de venopunción. Para llevar a cabo el desempeño de esta tarea se utilizó una cámara web, a la cual se le ha extraído el filtro que impide el paso de luz infrarroja y es sustituido por otro que lo permite. Para mejorar la detección de las venas se le agregó a la cámara un arreglo de LEDs emisores de luz infrarroja (830nm). Las imágenes obtenidas fueron procesadas mediante la ecualización del histograma adaptable y clasificadas por dos métodos, el primero basado en el algoritmo Fuzzy C-Means, el segundo basado en un modelo probabilístico de tipo Bayes, técnicas del área de inteligencia artificial, presentadas como alternativa en el procesamiento de imágenes. Para la obtención de las imágenes se consideraron las regiones anteriores y exteriores del antebrazo izquierdo y derecho de cada sujeto generando una base de datos. Este sistema también tiene aplicación en la detección de venas varicosas debido a que se puede dar un seguimiento a la dilatación de las venas.

ABSTRACT: The venipuncture, the catheterization and intravenous (IV) injections are some of the common procedures in the clinical practice. The location of the veins may be complex in some patients. In this paper a system able to enhance the vein distribution in a patient's forearm in order to help, in future works, to locate the veins in a non-invasive way and accomplish the IV procedures, is described. To carry out this work a web cam was used, the filter that blocks out the infrared light has been removed and replaced for one who does not. To increase the vein detection an array of infrared LEDs (830 nm) was attached. The resulting images were processed using the adaptive histogram equalization and then classified by two methods, the first one based on the Fuzzy C-Means Algorithm, and the second based in a Bayesian probabilistic model. For the image acquisition, the anterior-exterior regions of the left and right forearm of each subject were considered to generate a data base. This system also has relevance in the detection of varicose veins since is able to monitor the vein dilatation.

Valor de la Recompensa: ¿Cómo y Para Qué se Usa el Concepto? / Value of the Reward: How Is the Concept Used and for What? / Valor de Recompensa: como e para que se usa o Conceito?

El escrito ofrece un panorama general sobre el valor de la recompensa, respondiendo los interrogantes: ¿qué es?, ¿cómo se ha conceptualizado? y ¿qué investigaciones han utilizado el concepto? En sentido general, este se utiliza para calificar una recompensa como más o menos efectiva: mientras mayor sea el valor, mayor es su eficacia. Primero se describe la medición histórica del valor y cómo lo define la literatura sobre economía conductual. A continuación aparecen dos usos diferentes del concepto: (a) como constructo hipotético y (b) como variable interviniente. También se incluyen definiciones operacionales, en las que no se definen exhaustivamente las variables asociadas, entonces no se le considera variable interviniente, pero tampoco se agrega significado, más allá del nivel de observación, por lo que no son ejemplo de constructo hipotético. Posteriormente se explora la relación entre demora del reforzador y descuento temporal. Las consideraciones finales retoman la discusión sobre su valor heurístico en la investigación contemporánea.

The article offers a general panorama on the value of the reward, answering the questions: What is it? How has it been conceptualized? What investigations have used the concept? In general, a reward is rated as more or less effective: the greater the value, the greater its efficiency. First, the article discusses the historical measurement of value and how the literature on behavioral economics defines it. Next, two different uses of the concept are presented: (a) as a hypothetical construct and (b) as intervening variable. The text includes operational definitions where the associated variables are not defined exhaustively and therefore not considered as intervening variable, but which also add no meaning beyond the level of observation and therefore are not an example of a hypothetical construct. The article then explores the relationship between delay of the reinforcing agent and temporal discount. Finally, the article considers the discussion about the concept's heuristic value in contemporary research.

Este texto oferece um panorama geral sobre o valor da recompensa ao responder aos questionamentos: o que é, como vem sendo conceituado e quais pesquisas têm utilizado o conceito? Em sentido geral, este se utiliza para qualificar uma recompensa como mais ou menos efetiva: quanto maior for o valor, maior será sua eficácia. Primeiramente, descreve-se a medição histórica do valor e como a literatura sobre economia comportamental o define. A seguir, aparecem dois usos diferentes do conceito: (a) como construto hipotético e (b) como variável interventora. Também são incluídas definições operacionais, nas quais não se definem exaustivamente as variáveis associadas, portanto não é considerada variável interventora nem se agrega significado mais além do nível de observação, razão pela qual não são exemplos de construto hipotético. Posteriormente, explora-se a relação entre demora do reforçador e desconto temporal. As considerações finais retomam a discussão sobre seu valor heurístico na pesquisa contemporânea.

Elaborando uma cartilha sobre as ambiguidades da violência conjugal / The formulation of a brochure about the ambiguities of marital violence / Desarollando un folleto sobre las ambigüedades de la violencia conyugal

O texto é um relato de experiência em um projeto de extensão universitária que elaborou e testou junto a grupos comunitários uma cartilha sobre violência conjugal direcionada tanto a mulheres quanto a homens, tendo como proposta construir uma comunicação que explicitasse e avaliasse os diferentes sentimentos e crenças relacionados ao tema, e ainda que respeitasse as possibilidades e os desejos de cada leitor. A abordagem de intervenção comunitária foi ancorada no construcionismo social. O tema da violência conjugal foi apresentado na cartilha tendo por base um esforço para articular as contribuições advindas tanto dos movimentos feministas como de outros estudiosos, mantendo a politização do tema. O processo de produção da cartilha é relatado buscando refletir sobre as dificuldades e as mudanças vivenciadas diante dos textos sobre o tema, dos testes do primeiro esboço junto a grupos comunitários, dos consultores e de feministas, de forma a apontar o fato de nossa atenção ter se concentrado em quatro categorias de análise do problema: dominação masculina, diversidade, amor romântico e ambigüidades, sendo a última a que nos pareceu ser mais amplamente debatida e apreendida por qualquer vertente de discussão diante do tema, embora todas sejam imprescindíveis. Por fim, apontamos nossa avaliação sobre os limites e os potenciais da última versão da cartilha.(AU)

This paper is the experience account of a college extension project that elaborated and tested a brochure about marital violence with community groups directed to both women and men. Its purpose is to build a means of communication that explains and evaluates the different feelings and beliefs related to the issue, respecting the possibilities and wishes of each reader. The community intervention’s approach was anchored on social construccionism. The issue of domestic violence was presented in the brochure, based on an effort to link both the contributions from feminist movements as from other researchers, maintaining the politicization of the issue. The brochure’s production process is reported in an attempt to reflect about the difficulties and changes experienced in face of the texts about the subject, the first tests of the brochure with community groups, consultants and feminists. This work focused four categories of the problem analysis: male domination, diversity, romantic love and ambiguity. The last category seemed to have been widely discussed and understood by any aspect of the discussions on this subject, however all these themes are essential. Finally, we conclude our evaluation about the limits and the potential aspects of the last brochure’s version.(AU)
