Resumen El objetivo del presente trabajo fue diseñar y validar un instrumento computarizado de Stroop modificado con reactivos de contenido emocional, siguiendo el modelo bioinformacional. El estudio fue cuantitativo empírico analítico con diseño no experimental instrumental transversal. La muestra fue de 343 participantes (58.6% mujeres, 41.1% hombres), con edades entre 18 y 49 años (M=24.36, DE=6.49), a quienes se les registró el tiempo de respuesta ante los estímulos. Los resultados indicaron una consistencia interna favorable (α=.89), con una solución unidimensional (Interferencia) que explicaba el 63.75% de la varianza. Se concluyó que el instrumento es válido y confiable para evaluar interferencia emocional a nivel preatencional, así como facilitar las investigaciones sobre procesos atencionales y vulnerabilidad cognitiva.

Abstract The purpose of this study was to design and validate a computerized Stroop test modified with emotional content and based on the bioinformational model, to facilitate pre-attentional and cognitive vulnerability researches. A quantitative empirical study with a non-experimental instrumental cross-sectional design was conducted. The sample consisted of 343 participants (58.6% females, 41.1% males), aged between 18 and 49 years old (M=24.36, SD=6.49), who were recorded on the response time to the stimuli. Results indicated a favorable internal consistency (α=.89), with a one-dimensional solution (Interference), that explained 63.75% of total variance. It was concluded the instrument is valid and reliable to assess emotional interference at pre-attentional level and it makes possible research on attentional processes and cognitive vulnerability.

Abstract: Clear cell acanthoma is a rare, epidermal tumor not common in the area of the nipples; indeed, the literature describes only 8 cases, all showing unilateral presentation. We here report the first case of bilateral clear cell acanthoma with good response to topical corticosteroids. Case report: A sixteen-year old girl presented with 2 excrescent, fleshy, and exudative tumor masses in both nipples and areola mammae. A biopsy was conducted and confirmed clear cell acanthoma histopathologically. Treatment with strong corticosteroids resulted in rapid improvement and resolution. After one year of follow-up, the patient developed atopic dermatitis. Discussion: We describe the first case of bilateral clear cell acanthoma localized in the nipple/areola that resolved with powerful corticosteroids, suggesting a reactive etiology of the lesion.

Background: Quality of care and respect for the rights of users are critical to achieve positive health outcomes and respond appropriately to the expectations of people, particularly if they have mental illnesses. Aim: To carry out a baseline diagnosis of quality of care and respect for rights in public outpatient psychiatric services. Material and Methods: Quality of care and respect for patients’ rights was assessed by a mental health professional and a trained psychiatric service user in 15 ambulatory psychiatric services. The WHO QualityRights instrument was used, reviewing documentation and making observations in each facility, as well as interviewing 146 patients, 148 health care workers and 64 relatives of patients. Results: A high level of achievement was accomplished in terms of discrimination-free health care, availability of psychotropic medications, lack of abuse or neglect and use of informed consents. A low level of achievement was found in terms of user support to cope with community living, access to education or work and participation in community activities, respect for user treatment preferences and preventive measures to avoid maltreatment and cruelty. Conclusions: Chile could improve the performance of psychiatry services having laws based on the “Convention of Rights of Persons with Disabilities” and standards of the World Health Organization, having national policies about quality of care and rights of users, reinforcing the community work of mental health care teams, reinforcing and informing users about their rights and promoting research on interventions to improve the respect of their rights.

Resumen Objetivo: Determinar las características clínicas, daño y calidad de vida de una cohorte de pacientes colombianos con lupus eritematoso sistémico. Métodos: En un periodo de seis meses se recolectaron datos clínicos, sociodemográficos, se realizó SELENA-SLEDAI, BILAG, SLICC y SF-36, de pacientes con lupus, asistentes a dos centros de referencia de Bogotá D.C. Resultados: Se estudiaron 109 pacientes de los 440 registrados. El 91,7% de los pacientes fueron mujeres, el tiempo de evolución fue de 10.5 ± 8,86 años; 76,1% de los pacientes procedía del área urbana; 60,6% de los pacientes pertenecía a estrato socioeconómico bajo, 45% tenía menos de 5 años de enfermedad. En BILAG A el componente renal fue el más comprometido (11,9%). Por SELENA-SLEDAI, 45,9% de los pacientes se encontraba en remisión de la enfermedad. Por SLICC/ACR 45,9% presentó algún grado de daño orgánico. Para el SF-36, 83,5% de pacientes presentó puntaje menor o igual a 50 para el componente resumido de salud física y 74,3% para el componente resumido de salud mental. La correlación entre el puntaje del SF-36 componente físico (-0,21) y daño orgánico fue débil. Conclusiones: Las características clínicas y de actividad de la enfermedad, reportadas en el presente estudio se correlacionan con los datos publicados por series mundiales y latinoamericanas. Además, se observó importante compromiso en la calidad de vida.

Abstract Objective: To determine the clinical characteristics, activity, damage, and quality of life in Systemic lupus erythematosus in Colombian patients. Methods: Clinical and demographic data was collected over a six-month period, and the SELENA-SLEDAI, BILAG 2004, SLICC/ACR and SF-36 was used on patients with Systemic Lupus Erythematosus attending two referral Clinics in Bogota D.C. Results: A total of 109 patients from the 440 registered, of whom 91.7% were women. The time to progression was 10.5 ± 8.86 years, and 76.1% of the patients came from urban areas, 60.6% patients belonged to low socioeconomic status, and 45% had the disease for less than 5 years. In BILAG A, the renal component was the most affected (11.9%). According to SELENA-SLEDAI, 45.9% of patients were in remission. Using SLICC/ACR, 45.9% had some degree of organ damage. With the SF-36, 83.5% of patients had scoresof <+ 50 for the physical health components, and 74.3% had scores of <50 for the mental health component summary. There was a weak correlation between the SF-36 physical component score (-0.21) and organ damage. Conclusions: The clinical characteristics and disease activity reported in this study are similar to the data published by global and Latin American series. Additionally, we observed significant compromise in the quality of life.

Provincia de Misiones posee actualmente una actividad forestal en pujante crecimiento ubicándose entre las primeras del país. Este marco de desarrollo productivo permite predecir un ámbito de crecimiento favorecido por las nuevas condiciones del mercado internacional. Por otro lado a pesar del avance de la tecnología industrial, no se ha alcanzado el nivel de desarrollo biotecnológico óptimo que conjugue la calidad genética con características fenotípicas de excelencia en las especies maderables de mayor demanda en la Provincia basándose la selección en criterios netamente fenotípicos y en la experiencia del productor, sin contarse con métodos moleculares desarrollados en la región. Este trabajo presenta los resultados del Proyecto Federal de Innovación Productiva (PFIP Mi09) cuyo objetivo principal fue estandarizar y transferir al sector productivo un conjunto de marcadores moleculares microsatélites para ser aplicado al análisis de poblaciones y forestaciones de Araucaria angustifolia y Pinus taeda provenientes de la Provincia de Misiones (Argentina). Esto permitirá conocer el perfil genético de plantaciones y poblaciones de estas especies forestales, pudiendo aplicarse a la certificación de calidad en la producción forestal o a la selección de ejemplares de especies nativas.

Misiones Province currently has the first intensive forestry activity of Argentine. This framework of productive development allows predict an area of growth favored by the new conditions of the international market. On the other side despite the progress of industrial technology, has not been reached the optimal level of biotechnological development that combining quality with genomic and phenotypic characteristics of forest species. This work presents the results of Federal Project of Productive Innovation (PFIP Mi09) whose main objective was standardize and transfer to the productive sector a set of microsatellites molecular markers to be applied to the populations analysis of Araucaria angustifolia and Pinus taeda forestation from the Misiones (Argentine). This will reveal the plantations and forest genetic profile and may be applied to genetic certification of forest production quality.

La microestructura, estructura anatómica, la resistencia a la flexión y la energía requerida durante el corte de los tallos de tres variedades de caña de azúcar cultivadas en el Valle del Cauca (Colombia), fueron estudiados con el propósito de adquirir información útil para el desarrollo de cuchillas para corte de esta especie. Las labores de caracterización microestructural y anatómica se apoyaron en las técnicas de microscopía óptica y electrónica de barrido. Las propiedades mecánicas se determinaron adaptando algunas normas ASTM para maderas, mientras que la energía al corte se evaluó usando un péndulo de impacto tipo Charpy modificado. En los tallos de las tres variedades estudiadas se observaron diferentes distribuciones y dimensiones geométricas de las fibras y se verificó la presencia de partículas de sílice. Se presentó en general mayor requerimiento de energía específica al corte en los entrenudos que en los nudos y un menor consumo específico de energía al corte con las cuchillas con ángulo de afilado de 20°. Se establecieron relaciones entre la microestructura de los tallos, comportamiento a la flexión y al corte, destacándose la relación proporcional entre el área transversal efectiva de fibra (ATEF) y la energía específica al corte, así como entre el coeficiente de flexibilidad y el módulo de elasticidad en flexión.

The microstructure, anatomical structure, bending resistance and the energy required to cut stems of three varieties of sugar cane cultivated in the Valle del Cauca (Colombia ), were studied in order to have useful data for the development of cutting blades. Microestructural and anatomical characterization tasks were performed by optical microscopy (OM), and scanning electron microscopy (SEM). The physical and mechanical properties were determined after adaptation of ASTM standards (which were developed for wood), while the consumption of energy during cutting was evaluated by using a modified Charpy type impact pendulum. The fibers and silica particles showed different geometry and distribution in the stems of the three studied varieties, and a relation was established between the microstructure of the stems and the energy required to cut them in the modified Charpy pendulum. Generally speaking, cutting the internodes required higher specific energy than cutting the nodes, and the use of blades with cutting angle of 20° led to lower levels of energy consumption. Also, a relation of proportionality between the effective cross-sectional area of fibers (ATEF) and the specific energy consumed in cutting, as well as between the flexibility coefficient and the modulus of elasticity in bending were found.

SE LLEVÓ A CABO UN ESTUDIO OBSERVACIONAL retrospectivo en el Hospital Universitario San Vicente de Paúl, de Medellín, basado en la revisión de las historias de pacientes con tuberculosis osteoarticular, entre enero de 1994 diciembre de 2004; con base en los hallazgos se describen las características demográficas, clínicas, de laboratorio y de tratamiento de 47 pacientes que correspondían al 3.2% del total de casos de tuberculosis hallados en la década estudiada; 35 tuvieron tuberculosis de la columna vertebral y en 12 la enfermedad fue extraespinal; solo en 7 pacientes se halló el antecedente de tuberculosis pulmonar; 23 eran mujeres y 24, hombres, con edades entre 1 y 71 años; 18 eran menores de 12 años; los cultivos para Mycobacterium tuberculosis fueron positivos en 14 pacientes (29.8%) y las biopsias fueron compatibles con tuberculosis en 26 pacientes (55.3%); 11 de los 12 pacientes con tuberculosis extraespinal presentaban la tríada radiológica de Phemisther, constituida por osteopenia, osteolisis y disminución del espacio articular. Los síntomas predominantes en los pacientes con tuberculosis espinal fueron: dolor, síntomas neurológicos y deformidad, principalmente cifosis; radiológicamente estos pacientes tenían destrucción de cuerpos vertebrales y disminución del espacio articular, además de osteopenia. La tomografía se hizo en 19 pacientes y mostró compresión medular en 5; la resonancia magnética practicada a 17 pacientes reveló absceso paravertebral en todos ellos y compresión medular en 8. Se discuten los hallazgos a la luz de la información hallada en la literatura médica mundial y en el contexto de la situación de salud de la población colombiana.

An observational, retrospective study was performed at Hospital Universitario San Vicente de Paúl, in Medellín, Colombia, based on the clinical records of patients with bone and joint tuberculosis between January 1994 and December 2004; based on the findings, epidemiological, clinical, laboratory and therapeutic characteristics of 47 patients are described. These patients represented 3.4% of the total of tuberculosis cases found in this hospital during the studied period; 35 had spinal tuberculosis and in 12 the disease affected other bones; a history of pulmonary tuberculosis was found in only 7 patients; 23 were males and 24, females; their ages were between 1 and 71 years; 18 were younger than 12 years; cultures for Mycobacterium tuberculosis were positive in 14 patients (29.8%) and biopsies were consistent with tuberculosis in 26 (55.3%). Eleven of the 12 patients with extraspinal disease had the radiological findings of Phemisther. Predominant symptoms of spinal tuberculosis were: pain, neurological manifestations and deformity, mostly kyphosis. From the radiological point of view, these patients had destruction of vertebral bodies and decrease of articular space in addition to osteopenia. Tomography was performed in 19 patients and revealed medullary compression in 5 of them; magnetic resonance carried out in 17 patients showed medullary compression in 8 and paravertebral abscesses in the 17. Results are discussed on the basis of reports from the world medical literature and in the context of the health situation of the Colombian population.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A principal fonte de proteínas vegetais para alimentação humana e animal é fornecida pelos grãos de cereais e leguminosas. O conteúdo de aminoácidos solúveis totais foi determinado por HPLC em endospermas de milho (Zea mays L.) normal e mutantes opaco e floury. A concentração de aminoácidos solúveis totais variou entre os mutantes. Os mutantes o11 e o13 se destacaram com médias superiores, enquanto que mutantes o10, fl3 e fl1 apresentaram as menores médias. De maneira geral, para a concentração total de aminoácidos solúveis, os grãos dos mutantes foram similares aos seus tipos selvagens com exceção dos mutantes o11 e fl1 sendo que o primeiro apresentou valor maior que seu tipo selvagem W22, enquanto que o fl1 teve valor menor que o Oh43. Para metionina, os mutantes o2 e o11 e o tipo selvagem Oh43 apresentaram as mais altas concentrações deste aminoácido. Valores similares foram observados entre os mutantes e os tipos selvagens para concentração de outros aminoácidos analisados, tais como lisina e treonina. As altas concentrações sugeridas originalmente para estes mutantes devem ser devidas aos níveis destes aminoácidos incorporados nas proteínas de reserva, mas não na forma solúvel.

For human nutrition the main source of vegetable proteins are cereal and legume seeds. The content of total soluble amino acids in mature endosperm of wild-type, opaque and floury maize (Zea mays L.) mutants were determined by HPLC. The total absolute concentration of soluble amino acids among the mutants varied depending on the mutant. The o11 and o13 mutants exhibited the highest average content, whereas o10, fl3 and fl1 exhibited the lowest average content. In general, the mutants exhibited similar concentrations of total soluble amino acids when compared to the wild-type lines, with the clear exception of mutants o11 and fl1, with the o11 mutant exhibiting a higher concentration of total soluble amino acids when compared to its wild-type counterpart W22 and the fl1 mutant a lower concentration when compared to its wild-type counterpart Oh43. For methionine, the mutants o2 and o11 and wild-type Oh43 exhibited the highest concentrations of this amino acid. Significant differences were not observed between mutants for other amino acids such as lysine and threonine. The high lysine concentrations obtained originally for these mutants may be due to the amino acids incorporated into storage proteins, but not those present in the soluble form.
