RESUMENCuando se busca una mayor precisión en el análisis de decisiones complejas, se hace necesario recurrir a diferentes técnicas de la Investigación de Operaciones, particularmente en la Teoría de decisiones. Sin embargo, la mayoría de estas pueden ser inadecuadas para manejar desempates de elecciones o disparidad en decisiones grupales por determinadas razones. En este artículo ampliamos los casos de aplicación del esquema metodológico del Proceso de jerarquía analítica (AHP) para abordar problemas en consensos de expertos. Primero, se verifica que esta sea una técnica que garantice el conjunto de preferencias necesarias en un juicio de expertos, luego, aplicamos un procedimiento de priorización usando la media geométrica, para verificar, alcanzar y mejorar el nivel de consenso de grupo por medio de esta técnica de decisión. Finalmente, se ilustra el esquema desarrollado mediante un caso de aplicación en el sector de la logística industrial, llegando a resultados positivos que señalan su efectividad y aplicabilidad dentro del campo de la Teoría de decisiones.Palabras clave: Proceso de jerarquía analítica, teoría de decisiones, investigación de operaciones. ABSTRACTWhen finely analyzing complex decisions, it is necessary to use several methods of operational research, decision theory in particular. However, these normally cannot handle election tie-breakers or disagreement in group decisions for certain reasons. In this article, we extend the range of the methodological scheme of the analytical hierarchy process (AHP) to address problems in reaching consensus among experts. First, we verify that it is a technique that guarantees the necessary set of preferences in an expert judgment; then we apply a prioritization procedure with the geometric mean to verify, reach and improve the level of consensus of the group via this technique. Finally, through a case of application in the industrial logistics sector, the scheme developed is illustrated, reaching positive results that indicate its effectiveness and applicability within the field of the Decision Theory.
Xp11.2 translocation renal cell carcinoma (TRCC) is a rare and aggressive variant of renal cell carcinoma (RCC) when presenting in adults. We report a case of a man in his early 40s who was diagnosed with stage III Xp11.2 TRCC and underwent radical nephrectomy. Seven months following the surgery, an adrenal nodule and bilateral pulmonary nodules were discovered. He underwent cryoablation of the adrenal nodule and systemic treatment with daily pazopanib. He displayed stable disease for approximately 6 years. Following this period, multiple hospitalisations interrupted daily pazopanib therapy resulting in progression of disease. His regimen was then changed to ipilimumab and nivolumab, followed by current daily therapy with axitinib. The patient now shows stable disease in his 10th year after diagnosis. This case study demonstrates the efficacy of pazopanib for metastatic Xp11.2 TRCC and warrants further investigation to supplement the guidelines regarding the use of targeted therapy for TRCC.
A library of natural products and their derivatives was screened for inhibition of protein tyrosine phosphatase (PTP) 1B, which is a validated drug target for the treatment of obesity and type II diabetes. Of those active in the preliminary assay, the most promising was compound 2 containing a novel pyrrolopyrazoloisoquinolone scaffold derived by treating radicicol (1) with hydrazine. This nitrogen-atom augmented radicicol derivative was found to be PTP1B selective relative to other highly homologous nonreceptor PTPs. Biochemical evaluation, molecular docking, and mutagenesis revealed 2 to be an allosteric inhibitor of PTP1B with a submicromolar K i. Cellular analyses using C2C12 myoblasts indicated that 2 restored insulin signaling and increased glucose uptake.
BY CrossMark click for updates RESUMENEl obje vo del presente estudio fue analizar la estructura interna del cues onario AWARE 3.0 en drogodependen entes. Fueron evaluados 240 sujetos en tratamiento residencial (hombres n=205 y mujeres n=35) entre 18 y 61 años con la escala de señales de alerta a recaída AWARE. Los análisis confirmaron la existencia de un solo factor, además se probaron cinco modelos confirmatorios incluyendo el factor de método que demostró influir en el modelo original. El análisis de confiabilidad obtuvo puntuaciones adecuadas tanto para variables observadas como variables latentes que representaron igualdad a nivel conceptual y de unidades (modelo congenérico y tau-equivalente). Los resultados indican un mejor ajuste solo con el modelo de ítems directos además de plantearse una versión breve. Estos hallazgos brindan una nueva perspec va sobre la estructura del instrumento y una nueva versión que ayude a complementar la evaluación en el proceso de evaluación y detección de señales de alerta a recaídas.
