Viabilidad y fiabilidad de las pruebas de aptitud física en niños preescolares colombianos

El objetivo del estudio fue evaluar la viabilidad y confiabilidad de las pruebas de campo de aptitud física utilizadas en el estudio 'Fuprecol kids' en niños preescolares colombianos de 3 a 5 años. Un total de 90 niños en edad preescolar de 3 a 5 años participaron en el estudio. Los componentes de peso, altura, circunferencia de la cintura, aptitud cardiorrespiratoria (CRF), aptitud musculoesquelética (fuerza de la empuñadura y salto amplio de pie), velocidad-agilidad (carrera de 4 × 10 m) y flexibilidad (prueba de sentarse y alcanzar) se probaron dos veces (dos semanas de diferencia). La viabilidad de las pruebas (preescolares capaces de completar la prueba) varió de 96% en la prueba de CRF a 100% en las pruebas de aptitud musculoesquelética, velocidad-agilidad y flexibilidad. En general, los% TEM fueron 0.625% para el peso, 0.378% para la altura, 1.035% para el índice de masa corporal y 0.547% para la circunferencia de la cintura. Adicionalmente, todas las pruebas fueron sustancialmente confiables, para CRF (en etapas y vueltas, coeficiente de correlación de concordancia = 0.944 y 0.941, respectivamente) en ambos sexos y flexibilidad (coeficiente de correlación de concordancia = 0.949) en niñas. No hubo diferencias significativas en las pruebas de aptitud y las diferencias de medias de prueba en los niños (p > 0.05), excepto en CRF (vueltas p = 0.017). En las niñas, hubo diferencias en las variables CRF (etapas ( p = 0.017) y vueltas ( p = 0.013), y flexibilidad ( p = 0.002). Los resultados de este estudio indican que la batería de pruebas de 'niños Fuprecol', administrada por maestros de educación física, fue confiable y factible para medir los componentes de la aptitud física en preescolares en un entorno escolar en ColombiaThe aim of the study was to assess the feasibility and reliability of physical fitness field tests used in the “Fuprecol kids” study among Colombian preschool children aged 3–5 years. A total of 90 preschoolers aged 3–5 years participated in the study. Weight, height, waist circumference, cardiorespiratory fitness (CRF), musculoskeletal fitness (handgrip strength and standing broad jump), speed–agility (4 × 10 m shuttle run), and flexibility (sit and reach test) components were tested twice (two weeks apart). The feasibility of the tests (preschoolers able to complete the test) ranged from 96% in the CRF test to 100% in the musculoskeletal fitness, speed–agility, and flexibility tests. Overall, the %TEMs were 0.625% for the weight, 0.378% for the height, 1.035% for the body mass index, and 0.547% for the waist circumference. In addition, all tests were substantial reliable, for CRF (in stages and laps, concordance correlation coefficient = 0.944 and 0.941, respectively) in both sexes and flexibility (concordance correlation coefficient = 0.949) in girls. There were no significant differences in fitness test–retest mean differences in the boys (p > 0.05), except in CRF (laps p = 0.017). In girls, there were differences in CRF (stages (p = 0.017) and laps (p = 0.013)), and flexibility (p = 0.002) variables. The results from this study indicate that the “Fuprecol kids” battery of tests, administered by physical education teachers, was reliable and feasible for measuring components of physical fitness in preschoolers in a school setting in Colombi

An Approach to Measuring Colistin Plasma Levels Regarding the Treatment of Multidrug-Resistant Bacterial Infection

19 páginasAntimicrobial resistance to antibiotic treatment has significantly increased during recent years, causing this to become a worldwide public health problem. More than 70% of pathogenic bacteria are resistant to at least one of the currently used antibiotics. Polymyxin E (colistin) has recently been used as a “last line” therapy when treating Gram-negative multi-resistant bacteria. However, little is known about these molecules’ pharmacological use as they have been discontinued because of their high toxicity. Recent research has been focused on determining colistimethate sodium’s pharmacokinetic parameters to find the optimal dose for maintaining a suitable benefit–risk balance. This review has thus been aimed at describing the use of colistin on patients infected by multi-drug resistant bacteria and the importance of measuring this drug’s plasma levels in such patients

UNA REVISIÓN SOBRE LOS SISTEMAS DE LOCALIZACIÓN DE ROBOTS EN ENTORNOS INTERIORES: TÉCNICAS, TECNOLOGÍAS Y ALGORITMOS (A REVIEW ON ROBOT LOCATION SYSTEMS IN INDOOR ENVIRONMENTS: TECHNIQUES, TECHNOLOGIES AND ALGORITHMS)

Resumen El tema de posicionamiento en interiores es un desafío muy importante en la robótica. Dado que el Sistema de Posicionamiento Global (Global Positioning System - GPS) no está disponible en interiores, se deben considerar otros enfoques para localizar objetos en estos entornos. El objetivo de este trabajo es presentar una revisión de las principales técnicas, tecnologías y algoritmos utilizados en los Sistemas de Localización en Interiores (Indoor Positioning Systems - ISP). Actualmente existe con un amplio abanico de técnicas, tecnologías y algoritmos para estimar la posición de un objeto en entornos interiores. Después de revisar la literatura se propone una Red de Sensores Inalámbricos (Wireless Sensor Network - WSN) basada en la tecnología Bluetooth de bajo consumo de energía (Bluetooth Low Energy – BLE) y algoritmos de Multilateración (Multilateration - MLAT) para la localización en tiempo real de robots en movimiento. Las principales ventajas de los sensores BLE son el bajo costo implementación y consumo de energía; además, los algoritmos MLAT se distinguen por la eficiente implementación bajo diferentes tecnologías. Palabras clave: Sistemas de Localización en Interiores, Sistema de Posicionamiento Global, Bluetooth de Bajo Consumo de Energía, Indicador de Fuerza de la Señal Recibida, Multilateración. Abstract The indoor positioning issue is a very important challenge in robotics. Since the Global Positioning System (GPS) is not available indoors, other approaches for object location should be considered in these environments. The aim of this paper is to present a review of the main techniques, technologies, and algorithms used in the Indoor Positioning Systems (IPS). Currently, there is a wide range of techniques, technologies, and algorithms to estimate the position of an object in indoor environments. After reviewing the literature, a Wireless Sensor Network (WSN) based on Bluetooth Low Energy (BLE) technology and Multilateration algorithms (MLAT) are proposed for the real-time location of robots in motion. The main advantages of BLE sensors are the low implementation cost and energy consumption; besides, MLAT algorithms are distinguished by the efficient implementation under different technologies. Keywords: Indoor Positioning System, Global Positioning System, Bluetooth Low Energy, Received Signal Strength Indicator, Multilateration
