Abstract: Dado que lo que se entiende por tener compa eros de trabajo confiables puede tener diferentes respuestas, el objetivo de este estudio fue obtener un consenso en cuatro paneles de expertos sobre cuáles son las conductas y actitudes que favorecen la percepción de confiabilidad entre profesores y contrastarlo con un modelo de 5 dimensiones de la confiabilidad. Se realizaron 4 grupos Delphi, los expertos en total fueron 38 profesores universitarios pertenecientes a una Facultad de Ciencia Sociales. Los resultados muestran que el modelo propuesto es un marco parcialmente adecuado para comprender la confiabilidad. Se nombraron mas conductas y actitudes de benevolencia, sin embargo, lo que sería más importante para desarrollar la confiabilidad corresponde a la dimensión integridad. Se discute sobre cómo los profesores cultivan la confiabilidad en el trabajo Given it is understood what trustworthy co-workers can have different answers, the objective of this study was to obtain a concensus of four panels of experts of which are the behaviors and attitudes that favor the perception of trustworthiness among professors`, and to contrast it with a model of 5 dimensions of the trustworthiness.

Abstract: Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with high cardiovascular morbidity and mortality. Epicardial adipose tissue (EAT) thickness may act as a therapeutic target during treatments with drugs modulating the adipose tissue. We evaluate EAT thickness in RA patients treated with biological and nonbiological disease-modifying antirheumatic drugs (DMARDs). A cross-sectional study was conducted with a cohort of 34 female RA patients and 16 controls matched for age and body mass index (BMI). Plasma glucose, basal insulin, plasma lipids, and high-sensitivity C-reactive protein (hs-CRP) were assessed. EAT thickness and left ventricular mass (LVM) were measured by echocardiography. No significant differences in waist circumference (WC), blood pressure, fasting blood glucose, basal insulin, and lipid parameters were found between the groups. The control group showed lower concentrations () of hs-CRP and LVM () than those of the two RA groups. Patients treated with TNF-α inhibitors showed significantly lower EAT thickness than those treated with nonbiological DMARDs (8.56 ± 1.90?mm versus 9.71 ± 1.45?mm; ). Women with no RA revealed reduced EAT thickness (5.39 ± 1.52?mm) as compared to all RA patients (). Results suggest that RA patients have greater EAT thickness than controls regardless of BMI and WC. 1. Introduction Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with high cardiovascular morbidity and mortality [1]. Traditional risk factors along with inflammation and autoimmunity contribute to the development of coronary artery disease in RA patients [1]. Furthermore, a growing body of evidence has proved that these subjects present early alterations in some subclinical atherosclerosis markers [2, 3]. Tumor necrosis factor-alpha (TNF-α) is the key cytokine in RA inflammatory processes. Several clinical studies have proved that TNF-α inhibitors are effective in reducing the clinical signs of inflammation in RA patients whose treatment with nonbiological disease-modifying antirheumatic drugs (DMARDs) has been unsatisfactory [4, 5]. An additional benefit of the treatment with TNF-α inhibitors is the reduction in the risk of cardiovascular events [6]. Epicardial adipose tissue (EAT) thickness has recently emerged as new marker of cardiometabolic risk [7]. Clinically, the thickness of epicardial fat can be easily and accurately measured [8]. Epicardial fat thickness can serve as marker of visceral adiposity and visceral fat changes during treatments with drugs targeting the fat [9, 10]. A meta-analysis conducted

Abstract: in mexico, medicinal plants are widely used. the use of randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. interviews were carried out in jamapa, veracuz, mexico, with local residents to collect information about the traditional use of randia aculeata. in this locality, seven pieces of fruit from the plant are mixed in a liter of alcohol, and then administered orally against snakebites. by using histological techniques and a murine model, we explored its cytoprotective properties against the effects of crotalus simus and bothrops asper venoms. possible protections provided by the plant against tissue damage to skeletal and cardiac muscles and against the typical loss of red blood cells were analyzed. randia aculeata caused an increase in microhematocrit and total hemoglobin, parameters that are often decremented in association with the loss of red blood cells, which is a characteristic effect of animal venom. randia aculeata was also shown to protect against the lowering of platelet levels caused by bothrops asper venom. finally, randia aculeata produced a partial inhibition of necrosis following administration of snake venom in skeletal and myocardial muscles. the present results provide solid evidence for the traditional use of randia aculeata against snakebites, as demonstrated by protection against muscular tissue damage and the diminution of red blood cells.

Revista de la Asociación Espa?ola de Neuropsiquiatría , 1991,
Abstract: Derivada del cuestionario psicopatológico C.P.R.S., aparece en 1979 la "Montgomery Asberg Depression Rating Scale" concebida por sus autores como un instrumento altamente sensible para detectar los cambios en la sintomatología depresiva de los pacientes. Validada por sus autores originales en Inglaterra y Suecia, presentamos en este artículo un estudio de validación realizado sobre 147 pacientes franceses hospitalizados y diagnosticados de un trastorno afectivo según el DSM III. Obtuvimos resultados similares a los estudios precedentes que confirman una validez superior (sensibilidad = 94%, especificidad = 75% y mal clasificados = 6%), una más alta fiabilidad interexaminadores (K = 0,41 KW = 0,81) y sobre todo una mayor sensibilidad al cambio (S = 0,64 y 0,59) que las escalas de Hamilton y Beck consideradas hasta ahora como de referencia en su género

Agronomía Mesoamericana , 2003,
Abstract: El presente trabajo presenta resultados de la aplicación de metodologías participativas en el mejoramiento genético del frijol en dos regiones de Honduras. Se describen las metodologías y se presentan los resultados de las actividades de evaluación y selección, desde generaciones tempranas en poblaciones segregantes, hasta los ensayos de comparación del comportamiento de lí- neas avanzadas seleccionadas por métodos convencionales y participativos, y los ensayos de validación de líneas promisorias seleccionadas para estimar su potencial de adopción como variedad mejorada. Se mencionan los criterios de evaluaci ón y las decisiones para la selección optadas por los agricultores en la selección de líneas y variedades. Se discuten los resultados tratando de explicarlos según los principios y prácticas fundamentales en el mejoramiento de las plantas cultivadas. Finalmente, se identifican los beneficios del mejoramiento participativo con los agricultores, incluyendo aquellos relacionados con la adquisición de conocimientos y destrezas, y el incremento de la capacidad individual y colectiva en la toma de decisiones; así como las ventajas para los programas de mejoramiento bajo estos enfoques participativos.
