Using media to improve the informed consent process for youth undergoing pediatric endoscopy and their parents.

Background and study aims Youth undergoing pediatric endoscopic procedures and their parents demonstrate suboptimal comprehension of the informed consent (IC) process. We developed informational videos discussing key IC elements for pediatric endoscopy and evaluated their effects on youth and parental comprehension of the IC process. Patients and methods A randomized controlled trial of the video intervention was performed among youth undergoing endoscopy and their parents at an academic children's hospital. Randomization occurred at the time of enrollment using permutated blocks. Following the IC process with the proceduralist, subjects underwent structured interviews to assess IC comprehension. An Informed Consent Overall Score (ICOS: range 0 - 4) for comprehension was calculated. Results Seventy-seven pairs of children and their parents participated. Intervention recipients (N = 37 pairs) demonstrated higher ICOS scores as compared to control counterparts (mean (standard deviation): 3.6 (0.7) v. 2.9 (0.9), intervention v. control parents, P < 0.0001 and 2.7 (1.1) v. 1.7 (1.1), intervention v. control youth, P < 0.0001). Conclusions A media intervention addressing key elements of the IC process for pediatric endoscopy was effective in improving comprehension of IC for youth undergoing endoscopic procedures and their parents

Oxfendazole flukicidal activity in pigs

Although oxfendazole (OFZ) is a well know broad-spectrum benzimidazole anthelmintic, the assessment of its potential trematodicidal activity remains unexplored. OFZ administration at single high doses has been recommended to control Taenia solium cysticercus in pigs. The current study investigated the flukicidal activity obtained after a single high (30 mg/kg) oral dose of OFZ in pigs harbouring a natural Fasciola hepatica infection. Sixteen (16) local ecotype pigs were randomly allocated into two (2) experimental groups of 8 animals each named as follow: Untreated control and OFZ treated, in which animals received OFZ (Synanthic®, Merial Ltd., 9.06% suspension) orally at 30 mg/kg. At seven (7) days post-treatment, all the animals were sacrificed and direct adult liver fluke counts were performed following the WAAVP guidelines. None of the animals involved in this experiment showed any adverse event during the study. OFZ treatment as a single 30 mg/kg oral dose showed a 100% efficacy against F. hepatica. In conclusion, the trial described here demonstrated an excellent OFZ activity against F. hepatica in naturally infected pigs, after its administration at a single oral dose of 30 mg/kg.Fil: Ortiz, Pedro.

Climate change effects on groundwater recharge in Yucatan Peninsula. Application of water balance models to GCMs

The effects of climate change are significant on groundwater recharge. In regions with 15 socioeconomic structures highly dependent on this kind of water source, expected positive 16 and negative variations in temperature and precipitation respectively, will have a negative 17 effect on the recharge of groundwater and, consequently, on the future well-being of their 18 inhabitants. In this paper we aim at estimating the effect that changes in climatic 19 parameters will have on groundwater recharge in one of these areas: the Yucatan Peninsula 20 (Mexico). We apply a monthly water balance model to five distinct Global Circulation 21 Models in the near horizon (2015-2039), with RCP 4.5 and 8.5. In average terms, our 22 results estimate a current recharge between 118 ± 33 mm per year, which represents around 23 10 % of the total annual precipitation, and a reduction of 23% of groundwater recharge, a 24 result which clearly threatens the future socioecological equilibrium of the region.Preprin

Water societal metabolism in the Yucatan Peninsula. The impact of climate change on the recharge of groundwater by 2030

The demographic and economic growth in Yucatan peninsula (YP) in recent years has caused changes in the hydrological response and flow of the water cycle. The growth effects and its impact on society are poorly understood. Here we present an estimation of water consumption and its evolution based on the analysis of Yucatan Peninsula's societal metabolism, using the interdisciplinary tool MuSIASEM. Societal metabolism together with metabolic patterns generate a new narrative on how the YP development is linked to the uses of water, considering social functions, as well as the biophysical limits established by the annual recharge of groundwater, being it the main source of water supply. Given the current trends in YP socio-economic growth and climate change scenarios, our results show superlinear scaling relations between water metabolic rate and water consumption which leads increase in water consumption and 23% decrease in groundwater recharge by the year 2030. The consequences of this scenario are particularly worrying for the near future, given the current socio-economic structure in YP, highly dependent both on the services (i.e., tourism) and agriculture sectors.Peer ReviewedPostprint (author's final draft

Identification of individual and few layers of WS2 using Raman Spectroscopy

"The Raman scattering of single-and few-layered WS2 is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavelengths used in this study, the frequency of the A(1g)(C) phonon mode monotonically decreases with the number of layers. For single-layer WS2, the 514.5 nm laser excitation generates a second-order Raman resonance involving the longitudinal acoustic mode (LA(M)). This resonance results from a coupling between the electronic band structure and lattice vibrations. First-principles calculations were used to determine the electronic and phonon band structures of single-layer and bulk WS2. The reduced intensity of the 2LA mode was then computed, as a function of the laser wavelength, from the fourth-order Fermi golden rule. Our observations establish an unambiguous and nondestructive Raman fingerprint for identifying single-and few-layered WS2 films.

Mercado Mundial de Competencias Laborales

Las competencias laborales han tomado mayor relevancia en las últimas décadas donde las organizaciones modernas bajo el paradigma de la economía del conocimiento han incrementado la demanda de personal con habilidades que les garanticen niveles significativos de diferenciación y competitividad. Este trabajo tuvo como objetivo analizar las competencias laborales más solicitadas a nivel mundial mediante el Análisis de Redes Sociales (ARS), con la finalidad de identificar tanto a las regiones con mayor grado de co-ocurrencias como a los países con mayor concentración de competencias para determinar si se encuentran dentro del grupo de ingresos altos. También se presenta una red de co-ocurrencias entre países que permite valorar las sinergias regionales y las posibilidades de diversificación de las competencias laborales para el caso de México. Los hallazgos indican que Europa es la región de ingresos altos con mayor grado de co-ocurrencias regionales con Norteamérica y Asia Pacífico, mientras que la región de Latinoamérica y el Caribe se encuentra desvinculada de la red. Se detectan países del grupo de ingresos altos y de Europa dentro del top diez con una mayor concentración de competencias laborales, a excepción de Singapur, perteneciente a la región Asia Pacífico, con quien México presenta una sinergia regional

Ultra-light carbon nanotube sponge as an efficient electromagnetic shielding material in the GHz range

CVD synthesised CNT flexible sponge with density lower than 0.02 g cm⁻³ has been found to serve as high performance EMI shielding material without the aid of any polymer infiltration or impregnation. Due to its extreme lightweight, the specific SE of the CNT-sponge was found to be as high as 1100 dB cm³ g⁻¹, having a total SE above 20 dB in the whole 1-18 GHz range, and being able to shield by absorption. The material is the best of our knowledge this specific SE value appears to be the highest reported hitherto. Improved EM absorbers should fulfil the synergic requirements of being low reflective and highly absorptive. In our CNT-sponges this condition is not satisfied because, although their net absorption ability is strongly remarkable, their high electrical conductivity favours the wave to be reflected at the input interface. Therefore, this sponge material would have a great potential for microwave-frequency applications that need negligible reflection and great absorption when combined in a multilayered structure that could prevent the wave to be reflected at the input interface.This work was supported by Nanomod (MAT2010-17091) from the Spanish Ministerio de Ciencia e Innovación.
