Importancia de la hospitalización a domicilio en el paciente respiratorio crónico

Estamos asistiendo a un gran desarrollo de los programas de Hospitalización a Domicilio en nuestro país, ya que son numerosos los pacientes que se benefician de estos programas en la actualidad, ampliándose cada vez más los procesos subsidiarios de recibir atención domiciliaria. Entre estos pacientes debemos destacar los pacientes con patologías respiratorias crónicas.Dos datos para empezar que no dejan lugar a dudas en cuanto a la enorme cantidad de pacientes respiratorios crónicos que las unidades de Hospitalización a Domicilio (HAD) manejan a diario. Según el proyecto HAD 2020: una propuesta para consolidar la hospitalización a domicilio en España, en nuestro país existen 110 unidades de hospitalización domiciliaria que atienden entre 90.000-120.000 pacientes al año y se estima que entre 15-20% de estos pacientes sufren enfermedades respiratorias crónicas que generan 45.000 episodios de hospitalización domiciliaria anuales (1). Y por otra parte según la Asociación Internacional de Servicios de Información y Tecnología de Ciencias Sociales (IASIST) consultoría sanitaria que realiza revisión de estudios clínicos, en su publicación de Abril de 2016, la categoría diagnóstica mayor mas frecuente en HAD son las patologías respiratorias con un 30.5 % de los casos (2)

Micropropagation of Glandularia, native genus with ornamental potencial

En este trabajo se estableció un protocolo de propagación in vitro de tres especies nativas del género Glandularia: G. peruviana, G. sp. y G. laciniata. Para el establecimiento in vitro se evaluó el medio de Murashige Skoog (MS) con macro y micronutrientes diluidos a la mitad adicionado con 0,05 μM de bencilaminopurina (BAP) sola o en combinación con 0,1 μM thiadiazuron (TDZ) y un testigo sin reguladores del crecimiento. En la etapa de multiplicación se evaluó el medio de cultivo MS diluido a la ½ ó ¼ y adicionado de 20 ó 40 gr.L-1 de sacarosa. Es posible establecer y micropropagar estas especies en medios de cultivo sencillos. El medio más eficiente para el establecimiento fue aquel sin reguladores, mientras que el más adecuado para la multiplicación fue MS ½ adicionado de 20 gr.L-1 de sacarosa, en el cual la tasa de multiplicación cada 30 días fue de 6 en G. sp. y G. peruviana y 4 para G. laciniata.In this work there was established a protocol of microspropagation of three native species of the genus Glandularia, G. peruviana, G. sp. and G. laciniata. Macro and micronutrients half strength Murashige Skoog (MS) media added with BAP 0.05 μM alone or in combination with TDZ 0.1 μM were tested in the establishment stage. Half and quarter strength MS media with 20 or 40 g.L-1 of sucrose were assayed at multiplication stage. It is possible to establish and to micropropagate these species in simple culturing media. The most efficient media for establishment stage was that one without growth regulators, whereas the most suitable for the multiplication it was MS ½ with 20 g.L-1 of sucrose, where the multiplication rate every 30 days were 6 for G. sp and G. peruviana and 4 for G. laciniata.Fil: Ponce, María T..

The hinge morphology of SnO2 as multifunctional semiconductor: What we can learn from simulations, theory, and experiments

Our interaction with materials occurs through their surfaces whose properties are strongly dependent on morphology, structure, and atomic arrangement. Unfortunately, obtaining a detailed correlation between the surface morphology with its properties is not straightforward. SnO2 is a multifunctional semiconductor ceramic that is exploited in several technological devices from sensor to energy storage, water splitting, and solar to fuel photocatalysis. This work focused on the structural, energetic, and electronic properties of low and high index surfaces of SnO2 semiconductor and assessed the morphology-dependent process via first-principles calculations, at the density functional theory level. Importantly, our explicitly dynamic approach elucidates the atomic arrangements and stability of the exposed surfaces to provide a close match between experimental field emission scanning electron microscopy images and computational simulation. These findings can potentially set a foundation for establishing synthesis techniques for drive the morphology evolution through the control of temperature/pressure, and/or based on surface interactions of the selective adsorption of solvents/surfactants.This work was supported by Generalitat Valenciana, Universitat Jaume I, and São Paulo Research Foundation (FAPESP, grant number 2013/07296-2 and 2022/08048-1).

Vanadium Doping Effect on Multifunctionality of SnO2 Nanoparticles

 In the present study, tin oxide (SnO2) nanoparticles were synthesized by a precursor polymeric method. The obtained nanoparticles were doped with vanadium. The samples were characterized by powder XRD, TEM, optical UV and EPR studies. XRD and TEM showed the rutile crystal structure and its revealed that the lattice cell parameters and particles size were decreased with dopant level. Optical and EPR data confirmed that the doped V enters into SnO2 and distorted the host material symmetry. The films sensing characteristics have been studied from the aspect of doping level of sensing material and microstructure. It is found that V doping on SnO2 enhance sensor sensitivity towards CO gas. The results demonstrated that V doping can improving numerous applications which the SnO2 response is maximized

Novel approaches of nanoceria with magnetic, photoluminescent, and gas-sensing properties

The modification of CeO2 with rare-earth elements opens up a wide range of applications as biomedical devices using infrared emission as well as magnetic and gas-sensing devices, once the structural, morphological, photoluminescent, magnetic, electric, and gas-sensing properties of these systems are strongly correlated to quantum electronic transitions between rare-earth f-states among defective species. Quantitative phase analysis revealed that the nanopowders are free from secondary phases and crystallize in the fluorite-type cubic structure. Magnetic coercive field measurements on the powders indicate that the substitution of cerium with lanthanum (8 wt %), in a fluorite-type cubic structure, created oxygen vacancies and led to a decrease in the fraction of Ce species in the 3+ state, resulting in a stronger room-temperature ferromagnetic response along with high coercivity (160 Oe). In addition to the magnetic and photoluminescent behavior, a fast response time (5.5 s) was observed after CO exposure, indicating that the defective structure of ceria-based materials corresponds to the key of success in terms of applications using photoluminescent, magnetic, or electrical behaviors.Fil: Rocha, Leandro S.R..

DIGITAL DIVIDE IN PERUVIAN HIGHER EDUCATION: A POST-PANDEMIC REVIEW

By early 2020, the COVID-19 pandemic paralyzed the world, with the origin being the Chinese city of Wuhan. By March 11, 2020, the World Health Organization (WHO) declared COVID-19 a pandemic.  The dire consequences of this disease were reflected in a historic global recession, and in the health field, SARS-CoV-2 had wreaked havoc, especially in the elderly, due to worse manifestations and higher mortality rates. As a result, most countries were able to curb the spread of the virus by imposing mandatory measures such as not leaving their homes and very strict timetables. Among the measures considered was the closure of educational institutions, including universities. At that time, there was a paradigm shift in the way educators had to change the way they taught classes by making use of various online platforms. Online, distance and continuing education learning became a panacea for this unprecedented global pandemic for both educators and students. In this review, a passage is made through the different scenarios experienced by the COVID-19 pandemic, taking into account several objectives such as: the COVID-19, and the case of universities, the educational transition: from face-to-face to virtuality, challenges and opportunities after the pandemic, and last but not least, how the Peruvian State, was able to cope with the pandemic of Covid-19, and the challenges that should continue to be considered after the pandemic

Synthesis and defect characterization of hybrid ceria nanostructures as a possible novel therapeutic material towards COVID-19 mitigation

This study reports the synthesis of hybrid nanostructures composed of cerium dioxide and microcrystalline cellulose prepared by the microwave-assisted hydrothermal route under distinct temperature and pH values. Their structural, morphological and spectroscopic behaviors were investigated by X-Rays Diffraction, Field Emission Gun Scanning Electron Microscopy, High-Resolution Transmission Electron Microscopy, and Fourier-Transform Infrared, Ultraviolet–Visible, Raman and Positron Annihilation Lifetime spectroscopies to evaluate the presence of structural defects and their correlation with the underlying mechanism regarding the biocide activity of the studied material. The samples showed mean crystallite sizes around 10 nm, characterizing the formation of quantum dots unevenly distributed along the cellulose surface with a certain agglomeration degree. The samples presented the characteristic Ce–O vibration close to 450 cm−1 and a second-order mode around 1050 cm−1, which is indicative of distribution of localized energetic levels originated from defective species, essential in the scavenging of reactive oxygen species. Positron spectroscopic studies showed first and second lifetime components ranging between 202–223 ps and 360–373 ps, respectively, revealing the presence of two distinct defective oxygen species, in addition to an increment in the concentration of Ce3+-oxygen vacancy associates as a function of temperature. Therefore, we have successfully synthesized hybrid nanoceria structures with potential multifunctional therapeutic properties to be further evaluated against the COVID-19.Fil: Silva Rosa Rocha, Leandro.
