SATISFACCIÓN DEL USUARIO DEL ÁREA DE HOSPITALIZACIÓN DE UN HOSPITAL DEL TERCER NIVEL. MÉRIDA. VENEZUELA.

En esta investigación se valoró la satisfacción del usuario adulto de los servicios de hospitalización de un hospital de tercer nivel. Se consideró que la opinión de los usuarios es esencial para evaluar la calidad del cuidado de salud. La muestra fue de 210 personas, hospitalizadas en esta área, realizándose un estudio descriptivo, de campo y prospectivo. Los datos fueron obtenidos a través de un cuestionario diseñado por García (1993) el cual fue adaptado para esta población. Los resultados evidencian que el 82 % considera que el trato del personal de Enfermería es bueno y un 78 % opina que cuando requirieron la atención fueron atendidos satisfactoriamente. El 54 % respondió que fue atendido oportunamente, no así el 46 % por la alta demanda de usuarios. El 85 % de los usuarios expresan que el cuidado de Enfermería es bueno y que se les informaba sobre los medicamentos administrados. Se sugiere incentivar al personal de salud a continuar gestionando la calidad del servicio

Confinement Effects in Antiferromagnets

Phase equilibrium in confined Ising antiferromagnets was studied as a function of the coupling (v) and a magnetic field (h) at the surfaces, in the presence of an external field H. The ground state properties were calculated exactly for symmetric boundary conditions and nearest-neighbor interactions, and a full zero-temperature phase diagram in the plane v-h was obtained for films with symmetry-preserving surface orientations. The ground-state analysis was extended to the H-T plane using a cluster-variation free energy. The study of the finite-T properties (as a function of v and h) reveals the close interdependence between the surface and finite-size effects and, together with the ground-state phase diagram, provides an integral picture of the confinement in anisotropic antiferromagnets with surfaces that preserve the symmetry of the order parameter.Comment: 10 pages, 8 figures, Accepted in Phys.

Effects of the Addition of Ortho

The synthetic tetrapyrrole macrocycles, such as porphyrins (H2P) and phthalocyanines (H2Pc), exhibit interesting physicochemical properties suitable to be used in modern technology. For many applications, those species should be trapped or fixed inside graphite, hydrotalcites, silica, TiO2, or polymers. Methodologies for the optimization of the properties of porphyrins, trapped or fixed inside polymers, have been barely developed. Our research works in the development of methodologies for the optimization of incorporation and display of properties of tetrapyrrole macrocycles inside inorganic, polymeric, or hybrid networks. This paper shows some results about the effect of the spatial disposition of the amine (–NH2) groups attached on the periphery of substituted tetraphenylporphyrins, on the Nylon 66 structure and on the display of the physicochemical properties of the trapped macrocycles. Nylon 66 was synthesized from adipoyl chloride and hexamethylenediamine in presence of tetraphenylporphyrins substituted with –NH2 groups localized at the ortho- or para-positions of the phenyls. Cobalt complexes formation was used to quantify the amount of porphyrins in the polymer fibers. Characterization results show that the spatial position of amine groups of the porphyrins has important structural and textural effect on the Nylon 66 fibers and on the fluorescence of the porphyrins integrated into the fibers

Abnormal Distribution and Function of Circulating Monocytes and Enhanced Bacterial Translocation in Major Depressive Disorder

Introduction: Major depressive disorder (MDD) patients experience a systemic inflammatory stage. Monocytes play an important role in innate inflammatory responses and may be modulated by bacterial translocation. Our aim was to investigate the subset distribution and function of circulating monocytes, levels of proinflammatory cytokines, gut barrier damage, and bacterial translocation in MDD patients. Methods: Twenty-two MDD patients without concomitant diseases and 14 sex- and age-matched healthy controls were studied. The levels of circulating CD14++CD16- (classical), CD14++CD16++ (intermediate) and CD14- CD16++ (nonclassical) monocytes and the intracytoplasmic tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-10 expression in the presence or absence of lipopolysaccharide (LPS) stimulation were analyzed by polychromatic flow cytometry. The serum TNF-α, IL-1β, IL-6, and IL-10 levels were measured by Luminex. LPS-binding protein (LBP), intestinal fatty acidbinding protein (I-FABP), and zonulin were measured by enzyme-linked immunosorbent assay (ELISA). Results: MDD patients had a significant increase in the frequency of intermediate monocytes and a significant decrease in the frequency of classical monocytes compared to those in the healthy controls. MDD patients had a significantly increased percentage of classical monocytes that expressed IL-1β, intermediate monocytes that expressed IL-1β and IL6 and nonclassical monocytes that expressed IL-1β, and decreased levels of nonclassical monocytes that expressed IL6 compared to those in the healthy controls. MDD patients had significantly increased levels of circulating TNF-α, IL-1β, LBP, and I-FABP compared to those in the healthy controls. MDD patients with high LBP levels had a significant reduction in the number of circulating monocytes compared to that in the normal-LBP MDD patients, which can be mainly ascribed to a decrease in the number of intermediate and nonclassical monocytes. Conclusions: We have demonstrated that compared to the healthy controls, MDD patients show a marked alteration in circulating monocytes, with an expansion of the intermediate subset with increased frequency of IL-1β and IL-6 producing cells. These patients also exhibited a systemic proinflammatory state, which was characterized by the enhanced serum TNF-α and IL-1β levels compared to those in the healthy controls. Furthermore, MDD patients showed increased LBP and I-FABP levels compared to those in healthy controls, indicating increased bacterial translocation and gut barrier damage

XI CIDU. La transformación digital de la universidad Congreso Iberoamericano de Docencia Universitaria

Nesta comunicação apresenta-se uma experiência de gamificação realizada numa turma online, numa Universidade Virtual. Foram utilizados como elementos de jogo pontos, badges, leadboard, avatares e desafios. Do ponto de vista do desenho da unidade curricular, foi proposto um desafio global, sob a forma de roleplaying, que percorreu todo o semestre. Para este desafio global contribuíram três outros desafios, nos quais os estudantes deveriam dinamizar discussões, sendo atribuídos pontos e badges em função da sua prestação. No que se refere à metodologia, tratou-se de uma investigação exploratória, com carácter qualitativo. Como técnicas de recolha de dados, privilegiou-se a observação, realizada durante toda a unidade curricular, complementada por um questionário aos estudantes no final do semestre. Constatou-se que a estratégia adotada incentivou a participação ativa dos estudantes, tendo estes gostado da experiência. Verificaram-se, contudo, algumas limitações, pelo facto de os estudantes desta amostra serem adultos trabalhadores a frequentar uma licenciatura online, com outros compromissos profissionais e familiares. Com efeito, verificou-se que vários deles mencionaram ter dificuldade na gestão do tempo, limitando a possibilidade de adesão a um percurso exigente em termos de participação ativa.In this paper, we present a gamification experiment that took place in an online class at a virtual university. The game elements were points, badges, leaderboard, avatars and challenges. Taking into account the curricular unit design, a global challenge was proposed, in the form of roleplaying, and took place along the whole semester. Three other challenges contributed to this global challenge: the students had to dynamize debates, and received points and badges, according to their performance. In terms of methodology, it consisted in an exploratory research of a qualitative character. Observation, complemented by a questionnaire made available to the students at the end of the semester, were the chosen techniques for data collection. It was observed that the adopted strategy motivated the students’ active participation, who really enjoyed the experience. However, some limitations were also observed, once these students, attending an online First Cycle Degree, are adults who have professional and family responsibilities and commitments. Actually, several of them mentioned that the difficulty in organizing their time did limit the possibility of participating in the challenge, which was indeed demanding in terms of active participation.info:eu-repo/semantics/publishedVersio

The European Solar Telescope

The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design combines the knowledge and expertise gathered by the European solar physics community during the construction and operation of state-of-the-art solar telescopes operating in visible and near-infrared wavelengths: the Swedish 1m Solar Telescope, the German Vacuum Tower Telescope and GREGOR, the French Télescope Héliographique pour l'Étude du Magnétisme et des Instabilités Solaires, and the Dutch Open Telescope. With its 4.2 m primary mirror and an open configuration, EST will become the most powerful European ground-based facility to study the Sun in the coming decades in the visible and near-infrared bands. EST uses the most innovative technological advances: the first adaptive secondary mirror ever used in a solar telescope, a complex multi-conjugate adaptive optics with deformable mirrors that form part of the optical design in a natural way, a polarimetrically compensated telescope design that eliminates the complex temporal variation and wavelength dependence of the telescope Mueller matrix, and an instrument suite containing several (etalon-based) tunable imaging spectropolarimeters and several integral field unit spectropolarimeters. This publication summarises some fundamental science questions that can be addressed with the telescope, together with a complete description of its major subsystems

Country-level gender inequality is associated with structural differences in the brains of women and men

Gender inequality across the world has been associated with a higher risk to mental health problems and lower academic achievement in women compared to men. We also know that the brain is shaped by nurturing and adverse socio-environmental experiences. Therefore, unequal exposure to harsher conditions for women compared to men in gender-unequal countries might be reflected in differences in their brain structure, and this could be the neural mechanism partly explaining women's worse outcomes in gender-unequal countries. We examined this through a random-effects meta-analysis on cortical thickness and surface area differences between adult healthy men and women, including a meta-regression in which country-level gender inequality acted as an explanatory variable for the observed differences. A total of 139 samples from 29 different countries, totaling 7,876 MRI scans, were included. Thickness of the right hemisphere, and particularly the right caudal anterior cingulate, right medial orbitofrontal, and left lateral occipital cortex, presented no differences or even thicker regional cortices in women compared to men in gender-equal countries, reversing to thinner cortices in countries with greater gender inequality. These results point to the potentially hazardous effect of gender inequality on women's brains and provide initial evidence for neuroscience-informed policies for gender equality
