A comunicação da suspensão de cirurgias pediátricas: sentimentos dos familiares envolvidos no processo

A hospitalização é uma experiência complexa, sendo agravada no caso de necessidade de intervenção cirúrgica, principalmente quando o paciente é criança. Quando a cirurgia é suspensa, paciente e seus familiares podem apresentar sentimentos de insegurança, angústia e ansiedade. Este estudo teve como objetivo identificar e descrever a percepção de quinze mães e/ou responsáveis por crianças de 0 a 18 anos, internadas em um hospital, após receberem a notícia de que a cirurgia de seu filho foi suspensa. É um estudo descritivo, qualitativo, que utilizou o referencial teórico da Comunicação Interpessoal e o metodológico da Análise de Conteúdo. Os resultados evidenciaram que as suspensões de cirurgias pediátricas são fatos presentes na instituição, que trazem repercussões ao paciente e familiares, e à organização institucional; que a comunicação entre profissionais da saúde, pacientes e familiares é inadequada; que a atuação do enfermeiro na notícia da suspensão da cirurgia precisa ser efetiva.

Explicações de crianças internadas sobre a causa das doenças: implicações para a comunicação profissional de saúde-paciente

Esta pesquisa pretendeu estudar o desenvolvimento cognitivo e as explicações sobre a causalidade das doenças em crianças hospitalizadas, particularmente a influência nas explicações da experiência com doenças e da escolaridade. Participaram da pesquisa cinqûenta crianças brasileiras internadas em um hospital público, com diferentes diagnósticos e idade variando entre cinco e nove anos. O desenvolvimento cognitivo e as concepções sobre as causas das doenças foram avaliados dentro de um referencial piagetiano. Como em estudos anteriores, as crianças processaram as informações numa seqüência cognitiva previsível. Entretanto, as crianças internadas mostraram atraso na aquisição da conservação, e explicações com poucos elementos subjetivos, sem referências à própria doença. As causas atribuídas às doenças foram similares às apontadas por crianças de outros países. Foi estatisticamente significativa a relação entre a complexidade das explicações e o número de internações. A maioria da amostra, independente da idade e nível cognitivo, atribuiu o adoecimento à desobediência, possível mecanismo adaptativo ao desamparo, resultado que parece trazer implicações a serem consideradas quando se abordam pacientes infantis.

A equipe de saúde como mediadora no desenvolvimento psicossocial da criança hospitalizada

Num primeiro momento a criança se apropria do conhecimento por mediações externas, nas quais um objeto externo a ela, que pode ser um adulto, faz uma mediação entre ela e o conteúdo a ser adquirido. Assim, a hospitalização pode tornar-se um fator de risco no desenvolvimento psicológico da criança, tanto no âmbito cognitivo quanto no afetivo, caso suas potencialidades não sejam mediadas pela equipe de saúde, pois esta tem grande contato com a criança durante a internação. Foi investigado, como objetivo do estudo, o conhecimento do processo de desenvolvimento infantil por parte dos profissionais da saúde envolvidos no cuidado com crianças hospitalizadas, em um hospital-escola público do Estado de São Paulo. Participaram da pesquisa onze profissionais, entre técnicas e auxiliares de enfermagem, e os resultados indicam que estas consideram importantes alguns aspectos no cuidado com a criança, tais como estimulação da linguagem, atenção, brincadeira, vinculação, contato físico, porém não reconhecem estes aspectos como importantes para o desenvolvimento, e elegem profissionais específicos para tratarem de aspectos relacionados ao desenvolvimento infantil na internação, não se percebendo como mediadoras no processo de desenvolvimento psicossocial da criança hospitalizada.

Electrical properties of YSZ/NiO composites prepared by a liquid mixture technique

We report the preparation and characterization of yttria-stabilized zirconia/nickel oxide composites (YSZ/NiO). This composite is the precursor material of the cermet YSZ/Ni, which is used as solid oxide fuel cell anode material. The performance of the anode is strongly dependent on the microstructural properties of the cermet. Therefore, the control of the microstructure of the YSZ/NiO composite is a key step for the fabrication of high-performance anodes. In this study, the composites were prepared by a modified liquid mixture technique. Scanning electron microscopy analysis evidenced the good dispersion of the phases and that NiO nanoparticles are spread over the YSZ surface. Sintered pellets were studied by X-ray diffraction and impedance spectroscopy. The main results show that the composite is comprised of a well-dispersed mixture of the two phases. The electrical conductivity data show that there is a strong dependence of the transport mechanism on the relative composition of phases. (c) 2005 Elsevier Ltd. All rights reserved.

O limiar de esforço percebido (LEP) corresponde à potência crítica e a um indicador de máximo estado estável de consumo de oxigěnio

The perceived exertion has been a target of several investigations, many times with association with objective physiological indicators in exercise. Recently, the identification of the perceived exertion threshold (PET) was proposed in the water running, which presented no difference in relation to the critical velocity. Theoretically, both parameters would be indicators of the maximum steady state of variables such as V̇O2 and blood lactate. The objective of this work was to verify the coincidence between PET, critical power (PCrit) and an indicator of maximum V̇O2 steady state (PCrit') in cycle ergometer. Eight male participants were submitted to progressive effort test in order to determine V̇O2peak (46.7 ± 8.5 ml/kg/min) and to four rectangular tests until exhaustion for the estimation of the critical power model parameters, PET and PCrit'. The hyperbolic relation between mechanical power and time spent for the V̇O2peak to be reached in each test was used for the PCrit' estimation, considered as the asymptote in the power axis, and the portion of the anaerobic work capacity (CTAnaer) depleted up to the establishment of the V̇O2peak (CTAnaer'). In order to identify PET, the straight lines angular coefficients of the perceived exertion in time (ordinate) and the powers used (abscissa) were adjusted to a linear function that provided a point in the power axis in which the perceived exertion would be kept indefinitely stable. The parameters PCrit and CTAnaer were estimated by means of the power-time non-linear equation. In order to compare the estimations of PET, PCrit and PCrit', the analysis of variance ANOVA for repeated measurements was employed, and the associations were established through the Pearson correlation. CTAnaer and CTAnaer' were compared through the t test. PET (180 W ± 61 W), PCrit (174 W ± 43 W) and PCrit' (176 W ± 48 W) were not significantly different and the correlations were of 0.92-0.98. CTAnaer' (14,080 ± 5,219 J) was lower than CTAnaer (22,093 ± 9,042 J). One concludes that the PET predicts the intensity of PCrit and PCrit' with accuracy.

Microstructural and electrical properties of the sofc anode precursor YSZ/NiO composite prepared by A liquid mixture technique

A detailed study of the microstructural and electrical properties of the yttria-stabilized zirconia/nickel oxide (YSZ/NiO) composite was performed. This material is the precursor to the solid oxide fuel cell anode cermet YSZ/Ni. A liquid mixture technique was developed to produce the YSZ/NiO composite to fabricate high-performance SOFC anodes. This technique resulted in fine and homogeneous powders and specimens with high electrical conductivity. The combined results showed that this technique is suitable for the production of the anode cermet.

Deposition and photo-induced electrical resistivity of dip-coated NiO thin films from a precipitation process

Thin films of the semiconductor NiO are deposited using a straightforward combination of simple and versatile techniques: the co-precipitation in aqueous media along with the dip- coating process. The obtained material is characterized by gravimetric/differential thermal analysis (TG-DTA) and X-ray diffraction technique. TG curve shows 30 % of total mass loss, whereas DTA indicates the formation of the NiO phase about 578 K (305 C). X-ray diffraction (XRD) data confirms the FCC crystalline phase of NiO, whose crystallinity increases with thermal annealing temperature. UV-Vis optical absorption measurements are carried out for films deposited on quartz substrate in order to avoid the masking of bandgap evaluation by substrate spectra overlapping. The evaluated bandgap is about 3.0 eV. Current-voltage (I-V) curves measured for different temperatures as well as the temperature-dependent resistivity data show typical semiconductor behavior with the resistivity increasing with the decreasing of temperature. The Arrhenius plot reveals a level 233 meV above the conduction band top, which was attributed to Ni2+ vacancy level, responsible for the p-type electrical nature of NiO, even in undoped samples. Light irradiation on the films leads to a remarkable behavior, because above bandgap light induced a resistivity increase, despite the electron-hole generation. This performance was associated with excitation of the Ni 2+ vacancy level, due to the proximity between energy levels. © 2012 Springer Science+Business Media New York.

Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xIn xY0.1O3-δ cermet anodes for IT-SOFC application

Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and chemical stability, is yet to be achieved. In this study we investigated the influence of indium on the chemical stability, microstructural and electrical characteristics of proton conducting NiO-BaCe0.9-xInxY0.1O 3-δ (NiO-BCIYx) anodes. Four compositions of cermet anode substrates NiO-BCIYx were prepared using the method of evaporation and decomposition of solutions and suspensions (EDSS). Sintered anode substrates were reduced and their microstructural and electrical properties were examined before and after reduction as a function of the amount of indium. Anode substrates tested on chemical stability in the CO2 atmosphere showed high stability compared to anode substrates based on commonly used doped barium cerates. Microstructural properties of the anode pellets before and after testing in CO2 were investigated using X-ray diffraction analysis. Impedance spectroscopy measurements were used for evaluation of electrical properties of the anode pellets and the conductivity values of reduced anodes of more than 14 S cm-1 at 600 °C confirmed percolations through Ni particles. Under fuel cell operating conditions, the cell with a Ni-BCIY20 anode achieved the highest performance, demonstrating a peak power density 223 mW/cm2 at 700 °C confirming the functionality of Ni-BCIY anodes.© 2013 Elsevier B.V.

Cuidado ao paciente idoso hospitalizado: implicações para a equipe de enfermagem

The Brazilian population is ageing rapidly, and chronic diseases have increased. Due to deficient health care services, the diagnosis and treatment of such diseases occur in the tertiary level, which increases costs and reduces the possibilities of early diagnoses. In view of the elderly population‟s increase and of the great demand at hospitalization units, it is important to learn about the difficulties and facilities faced by nursing teams when giving care to hospitalized individuals. In order to reach the objectives, a cross-sectional, prospective, descriptive, analytical and qualitative study was performed with basis on Bardin‟s Content Analysis. Among the difficulties were patients‟ limitations, dependence level, behaviors and habits, interference from companions, feeling of abandonment, perception of needs, dealing with suffering and lack of time for adequate care. As to facilities, acceptance of the disease, adherence to treatment, collaboration, trust in the team, and older patients‟ politeness were reported, which shows that passiveness is an important indicator in caring for the elderly. Older individuals suffer the outcomes of certain physical, psychological and mental deficits. When facing disease conditions, they require special care, including hospitalization and greater attention. The nursing team provides daily care and follows patients‟ development; however, its members are still not knowledgeable enough about the ageing process. This contributes to increase prejudice and erroneous stereotypes about older persons. Therefore, not understanding such process compromises the full care to be provided to older patients. This leads team members to accelerate the care provision process in order to meet the daily work demand, thus compromising older patients‟ autonomy and making them more dependent on the team, whereas the process should follow the opposite path
