Evaluación de los docentes como medio para el aseguramiento de la calidad académica
La educación impartida en las Universidades es una respuesta a la demanda de conocimiento de las habitantes de una comunidad resultando en acciones de desarrollo sustentable y progreso de las mismas. Los docentes constituyen un factor preponderante en las instituciones de educación superior universitaria, impartiendo los conocimientos, como gestor de aprendizajes y como orientador de los estudiantes. En este contexto se observa un renovado interés por la evaluación del trabajo de los docentes en el aspecto académico. El objetivo del estudio fue evaluar el nivel del desempeño de los docentes del primer curso durante el primer semestre del año 2011 en la facultad de Odontología de la Universidad Nacional de Caaguazú (UNC@)
Suicide risk after bariatric surgery
Indexación: Web of Science; Scopus; Scielo.Bariatric surgery is considered the most effective treatment for severe obesity and its benefits include improvement in medical comorbidities. However, a higher rate of suicides after this type of surgery has been reported. We performed a literature review on the subject, and concluded that the mentioned increase in suicide rates, compared to the general population, is probably caused by conditions that the patient had before surgery, especially psychiatric disorders such as depression or eating disorders. These are risk factors for suicide, and are more common in the population with indication for bariatric surgery. Therefore, it is necessary to thoroughly evaluate these patients before surgery searching for suicide risk factors, deriving them to a mental health professional if necessary and follow their mental health after surgery. Considering that the literature on the topic is inconsistent, further research is needed.Bariatric surgery is considered the most effective treatment for severe obesity and its benefits include improvement in medical comorbidities.

Los sitios web académicos con información de postgrado: herramientas para su evaluación / Postgraduate studies websites: a framework for evaluating
This paper proposes two tools for evaluating the quality of information on postgraduate studies websites, while providing for both objective and subjective approaches to the evaluation process. On one hand, a checklist of accessibly levels, for use with Weblink Validator, W3C markup validation service and TAW, has been developed. This is complemented by questionnaire instrument, designed and field tested to assess qualitative aspects of the target websites. These tools have been field tested on postgraduate websites that enjoy Quality Mention (MC) from universities in Andalusia, Spain; and the data complied was analyzed using the Statistical Package for the Social Sciences (SPSS). The results of these analyses yield acceptable quality values for these websites, while revealing several common flaws. A university website ranking and a website domain ranking have also been developed. The distinct quality levels of these websites are reported in cluster and principle component analyses
Alimentación basada en plantas: sus mecanismos en la prevención y tratamiento de la obesidad: Whole food plant based diet: its mechanisms for the prevention and treatment of obesity
Obesity is a metabolic condition with a continuous increasing rate, being considered today a “pandemic”. Due to this and the vast number of diseases it is associated with, there is a need for a treatment of this condition that is both effective and healthy in a comprehensive way. In this context, the concepts of lifestyle medicine and plant-based diets have emerged in medicine and in scientific research, and the latter have demonstrated benefits in all these areas and are being part of several scientific association’s recommendations today. In this article, a plant-based diet is briefly defined, and the mechanisms by which this type of diet provides benefits for the control of body weight are explored, including the satiety it generates and its characteristic low caloric density, the higher thermic effect of foods, the positive modulation of the gut microbiota, its effects on the insulin sensitivity, the absence of animal protein and how this affects the body weight, and the effects it has on the leptin hormone. Plant-based diets has been studied both in observational and interventional studies and positioned as a great alternative for the prevention and treatment of obesity, in addition to being a safe and health dietary pattern. We hope that in the future, more health professionals consider this evidence and incorporate it as part of their therapeutic tools.La obesidad es una condición metabólica que se encuentra en constante crecimiento, siendo considerada incluso una “pandemia” en la actualidad. Debido a esto y al gran número de enfermedades a las que se asocia, surge la necesidad de un manejo de esta condición que sea efectivo y saludable a nivel integral. En este contexto, entran a la medicina e investigación científica los conceptos de medicina de estilos de vida y de alimentaciones basadas en plantas, habiendo estas últimas demostrado beneficios en todas estas áreas de la salud, y están siendo parte de varias de las recomendaciones de sociedades científicas actuales. En este artículo, se explicará brevemente qué es la alimentación basada en plantas, explorando los distintos estudios observacionales e intervenciones que fundamentan su uso, y se propondrán algunos mecanismos a través de los cuales provee beneficios en el control del peso corporal, entre los cuales destacan: la saciedad que genera y la baja densidad calórica que la caracteriza, el mayor efecto térmico de las comidas, la modulación favorable de la microbiota intestinal, sus efectos sobre la sensibilidad a la insulina, la ausencia de proteína animal y cómo esto afecta el control de peso corporal, y los efectos que produce sobre la hormona leptina. La alimentación basada en plantas se posiciona como una gran alternativa para la prevención y tratamiento de la obesidad, siendo además un patrón alimentario seguro y saludable. Se espera que en el futuro cada vez más profesionales de la salud consideren esta evidencias y lo incorporen como parte de sus herramientas terapéuticas
