Introducción: el Índice de Movilidad de De Morton® (en inglés De Morton Mobility Index: DEMMI®) es una escala, válida y fiable para evaluar la movilidad funcional del adulto mayor. Objetivo: validar una versión en español para pacientes hospitalizados en una sala general. Material y métodos: traducción y adaptación transcultural, evaluación de la fiabilidad interobservador y validación de criterio explorando la correlación entre los índices DEMMI y Barthel® al ingreso hospitalario y también entre la percepción subjetiva del cambio en la movilidad por parte del propio paciente y la del puntaje DEMMI, y además evaluando la asociación entre este y el grado de acompañamiento requerido en el egreso hospitalario (n = 87). Su consistencia interna fue evaluada mediante los coeficientes de Kuder y Richardson (KR) y de Cronbach (n = 104). Resultados: la correlación entre los puntajes DEMMI y Barthel fue buena (Spearman's Rho = 0,78: p ≤ 0,0001), mientras que la correlación entre la percepción del paciente respecto del cambio en su movilidad y la variación en el puntaje DEMMI fue moderada (Spearman's Rho = 0,50; p < 0,0001). Quienes fueron dados de alta con alto nivel de acompañamiento habían tenido al ingreso un puntaje DEMMI inferior (28,1; IC 95%, 24,9 a 31,3) al de quienes no lo requirieron (48; 44,4 a 53,0). La consistencia interna fue adecuada (KR = 0,827 y Cronbach = 0,745; Pearson's Rho = 0,7885; p < 0,00001). Conclusión: la consistencia interna y la fiabilidad interobservador de la versión en español del puntaje DEMMI son buenas, mientras que sus cambios tienen buena correlación con los percibidos por los propios pacientes. Consideramos que puede ser usado como un elemento más para estimar al momento del ingreso hospitalario, el grado de acompañamiento que requerirán al ser dados de alta. (AU)

Introduction: the De Morton Mobility Index (DEMMI) is a valid and reliable scale to evaluate the functional mobility of the elderly. Aim: validate a Spanish version for hospitalized patients in a general ward. Material and methods: translation and cross-cultural adaptation, evaluation of inter-observer reliability and criterion validation exploring the correlation between DEMMI and Barthel scores at hospital admission and also between the subjective perception of the change in mobility by the patient himself and that of DEMMI score, and also, evaluating the association between DEMMI and the degree of support required at hospital discharge (n = 87). Its internal consistency was evaluated using Kuder-Richardson (KR) and Cronbach (n = 104) coefficients. Results: correlation between DEMMI and Barthel scores was good (Spearman's Rho = 0.78: p < = 0.0001), while correlation between patient's perception of change in mobility and variation in DEMMI score was moderate (Spearman's Rho = 0.50; p < 0.0001). Those discharged with a high level of support had a lower DEMMI score upon admission (28.1; 95% CI 24.9 to 31.3) than those who didn´t require it (48; 44.4 to 53.0). Internal consistency was adequate (KR = 0.827 and Cronbach = 0.745; Pearson's Rho = 0.7885; p < 0.00001). Conclusion: internal consistency and interobserver reliability of the Spanish version of DEMMI score are good, while its changes correlate well with those perceived by the patients themselves. We consider that it can be used as another element to estimate at hospital admission, the degree of support they will require upon discharge. (AU)

BACKGROUND: During a cross-sectional study on allergic aspergillosis in Chronic Obstructive Pulmonary Disease patients in Bogotá, Colombia, we reported the case of a 65-year-female patient with GOLD 2011 D classification, presenting dyspnea at the time of visit and aspergillus in repeated sputum cultures. METHODS: The isolate was identified at the section level based on macroscopic and microscopic characteristics and gene sequencing was used for precise molecular identification. Antifungal sensibility was determined by Sensititre YeastOne™ while virulence was assessed using a Galleria mellonella larvae model. RESULTS: The clinical isolate was first identified as Aspergillus section Flavi and sequencing of ß-tubulin and calmodulin genes, in addition to the identification of alfR (aflatoxin regulator) gene, allowed the undoubted identification of the clinical isolate as Aspergillus caelatus. It exhibited virulence in G. mellonella similar to A. flavus and a high in vitro susceptibility against all antifungals except for amphotericin B. CONCLUSION: This is the first human case of airway colonization attributed to A. caelatus. Resistance pattern justified the interest to discriminate this cryptic species.

The physiological and metabolic mechanisms behind the humic acid-mediated plant growth enhancement are discussed in detail. Experiments using cucumber (Cucumis sativus) plants show that the shoot growth enhancement caused by a structurally well-characterized humic acid with sedimentary origin is functionally associated with significant increases in abscisic acid (ABA) root concentration and root hydraulic conductivity. Complementary experiments involving a blocking agent of cell wall pores and water root transport (polyethylenglycol) show that increases in root hydraulic conductivity are essential in the shoot growth-promoting action of the model humic acid. Further experiments involving an inhibitor of ABA biosynthesis in root and shoot (fluridone) show that the humic acid-mediated enhancement of both root hydraulic conductivity and shoot growth depended on ABA signaling pathways. These experiments also show that a significant increase in the gene expression of the main root plasma membrane aquaporins is associated with the increase of root hydraulic conductivity caused by the model humic acid. Finally, experimental data suggest that all of these actions of model humic acid on root functionality, which are linked to its beneficial action on plant shoot growth, are likely related to the conformational structure of humic acid in solution and its interaction with the cell wall at the root surface.

Agriculture is the sector with the greatest water consumption, since food production is frequently based on crop irrigation. Proper irrigation management requires reliable information on plant water status, but all the plant-based methods to determine it suffer from several inconveniences, mainly caused by the necessity of destructive sampling or of alteration of the plant organ due to contact installation. The aim of this work is to test if terahertz (THz) time domain reflectance measurements made on the grapevine trunk allows contactless monitoring of plant status. The experiments were performed on a potted 14-years-old plant, using a general purpose THz emitter receiver head. Trunk THz time-domain reflection signal proved to be very sensitive to changes in plant water availability, as its pattern follows the trend of soil water content and trunk growth variations. Therefore, it could be used to contactless monitor plant water status. Apart from that, THz reflection signal was observed to respond to light conditions which, according to a specifically designed girdling experiment, was caused by changes in the phloem. This latter results opens a promising field of research for contactless monitoring of phloem activity.
