Desempenho e efeitos agudos da espirometria de incentivo volume-orientada sobre os volumes pulmonares em pacientes após AVC e sujeitos saudáveis

O Acidente Vascular Cerebral (AVC) é uma síndrome clínica caracterizada por uma perturbação focal da função cerebral. Geralmente ocasiona quadro de disfunção motora acompanhada de prejuízo da função respiratória. Tendo em vista tal quadro e suas possíveis repercussões, a fisioterapia respiratória tem sido amplamente requisitada com o intuito reverter ou minimizar as complicações. Dentre os recursos utilizados para este fim, os espirômetros de incentivo são utilizados com o objetivo de restaurar os volumes pulmonares, modificando o padrão respiratório e de ventilação pulmonar, prevenindo a incidência das complicações pulmonares. O objetivo do presente estudo foi comparar o desempenho na realização da espirometria de incentivo volume-orientada (EI) e seus efeitos agudos sobre os volumes pulmonares em pacientes após AVC e sujeitos saudáveis. Foram selecionados 40 voluntários, de ambos os gêneros, divididos em grupo experimental (GE), composto por 20 pacientes após AVC e grupo controle (GC) composto por 20 sujeitos saudáveis, pareados quanto à idade, gênero e Índice de Massa Corpórea (IMC). A coleta dos dados foi realizada em duas etapas: (1) Avaliação cognitiva e neurofuncional (Mini Exame do Estado Mental, National Institute Stroke Scale, Medida de Independência Funcional, teste de desempenho da aprendizagem) (2) Avaliação Respiratória (espirometria, manovacuometria e cinemática tóraco-abdominal, através da Pletismografia Opto-eletrônica). A análise estatística foi realizada através do software Graphpad Prism 4.0, em que foram utilizados os testes t Student e ANOVA two-way para comparação intergrupos e adotado nível de significância de 5%. Os resultados mostraram que os pacientes apresentam desempenho inferior na aprendizagem da espirometria de incentivo, com uma média de erros maior 2,95 ± 1,39, quando comparados aos sujeitos saudáveis, 1,15 ± 0,98. Em relação à prática observacional utilizada não foi encontrada diferença entre a aprendizagem através do vídeo ou do terapeuta. Em relação aos efeitos agudos da espirometria de incentivo volume-orientada, os pacientes após AVC apresentaram valores de volume corrente 24,7%, 18% e 14,7% inferiores quando comparados aos sujeitos saudáveis nos momentos pré-EI, EI e pós-EI, porém a espirometria de incentivo induziu incrementos de volume similares em ambos os grupos estudados, com 75, 3% para os pacientes e 73,3% para os sujeitos saudáveis. A espirometria de incentivo promove ganhos significativos no volume corrente da parede torácica, tanto em pacientes acometidos por AVC como em sujeitos saudáveis, no entanto o desempenho da aprendizagem é inferior para os pacientes, para ambas as práticas com vídeo ou terapeuta

Parahyba ou João Pessoa? Um estudo sobre a função social da História

Este trabalho é uma discussão sobre as funções sociais da História e da Memória. Para tanto, foi pensado diante do 80º aniversário da Revolução de 1930, marco da (re)fundação da capital paraibana, pois esta memória e a produção historiográfica a respeito do tema nos é bastante instigante. Falar de João Pessoa, seja da cidade, seja do indivíduo; no que se refere aos episódios de 1930, é tocar em um assunto bastante passional, onde chegar a um consenso é algo extremamente improvável. O objetivo deste trabalho é problematizar as funções sociais da História e suas utilizações, notadamente por meio do nosso objeto de estudo, buscando contribuir para a compreensão de como a memória e a escrita da História são frutos do trabalho constante das sociedades que as engendram. Estudar sobre a produção da memória e da historiografia bem como a função da escrita da História sobre esses episódios, entendendo-os como espaços específicos de disputas, notadamente sobre os embates de memórias nos últimos dez anos, trazendo novas reflexões sobre as funções sociais destas memórias

Avaliação clínica e comparativa da oclusão balanceada bilateral e desoclusão com guia canino sobre a função mastigatória de usuários de prótese total removível

The maintenance of masticatory function is especially important for patients who wear complete dentures due to the limitations of this type of prosthesis. Thus, the bilateral balanced occlusion (BBO) is used to achieve, besides other advantages, greater masticatory efficiency. However, analyzing critically the literature, it is observed that there is not enough scientific evidence that support the BBO as the most appropriate occlusal concept in complete dentures. This way, the purpose of the present study was to verify if complete dentures wearers with BBO present better masticatory efficiency and capacity than those with canine guidance (CG). A double-blind controlled crossover clinical trial was conducted. The sample was made of 24 completely edentulous patients. The subjects wore sets of complete dentures with both occlusal concepts for equal periods of 3 months. Objective data were collected through the masticatory efficiency test, performed by the colorimetric method, in which capsules of a synthetic material enclosing fuchsine- containing granules were used. Subjective data were recorded by patient´s ratings of their chewing function, which is the masticatory ability. No significant statistical difference was found for masticatory efficiency (p=0,0952) and masticatory ability (x2=0,5711/ p=0,4498) between the two occlusal concepts studied, as well as there was no correlation between these two variables (p=0,2985). Based on these results, it seems reasonable to use CG for the setup of complete dentures, since it is an easier and quicker technical procedure, until that future researches can come to complement this question

Relação entre o ciclo sono e vigília e a função cardiorrespiratória em estudantes de medicina

Students, normally, present an irregular sleep pattern characterized by delays in sleep onset and offset from weekdays to weekends, short sleep duration on weekdays and long sleep duration on weekends. The reduction of the necessary sleep and the irregularity in the sleep patterns provoke relevant short- and long-term impairments on performances, for example, in cardiorespiratory function. The cardiorespiratory performance represents, in addition to fitness, traces associated to health conditions and in several studies to pattern and/or individual s sleep quality. The aim of this study was to evaluate the pattern of the sleep-wake cycle and the cardiorespiratory function of medical students under different class schedules. The study was accomplished with two classes of medical students of UFRN, one had classes at 7 am (n = 47) and the second had classes at 8 am (n = 41) during the week. On the first stage of the study all volunteers filled out an anamnesis, the International Physical Activity questionnaire, the Pittsburgh index of sleep quality, the Portuguese version of the Horne and Östberg cronotype questionnaire, the Health and Sleep questionnaire and the Epworth Scale of Somnolence (ESS). On the second stage, 24 students (12 of each class) had their activity rhythm monitored by actimeters set to record activity at a 2-min interval for 14 days concomitant to the completion of the sleep diary. In this same stage, each volunteer performed the effort test (treadmill) only once in the morning period (between 9:00 and 11:00). The students showed an irregular pattern of the sleep-wake cycle and this irregularity is strongly influenced by the class schedules, in addition to the contribution of the academic demand, social activities and endogenous factors. The students who woke up earlier showed greater irregularity in the sleep-wake pattern. The earlier was the class schedule the worse was the sleep quality and the greater was the frequency of students with excessive diurnal somnolence. The classes schedules and the irregular pattern of the sleep-wake cycle did not show effect on the cardiorespiratory performance of the medical students. The performance on the test seems to be affected by other factors, which can be related to the pattern of the sleep-wake cycle or not. Therefore, it is suggested that the late start of classes provokes less irregularity on the pattern of the sleep-wake cycle. However, it was observed that this irregularity and the class schedule seem not to affect the cardiorespiratory performance directly

Investigação da estabilidade térmica e das propriedades elétricas do TiO2 em função da dopagem com Ce(SO4)2

The metalic oxides have been studies due to differents applications as materials semiconductor in solar cells, catalysts, full cells and, resistors. Titanium dioxide (TiO2) has a high electric conductivity due to oxygen vacancies. The Ce(SO4)2.2H2O doped samples TiO2 and TiO2 pure was obtained sol-gel process, and characterized by X-ray diffractometry,thermal analysis, and impedance spectroscopy. The X-ray diffraction patterns for TiO2 pure samples shows at 700°C anatase phase is absent, and only the diffraction peaks of rutile phase are observed. However, the cerium doped samples only at 900°C rutile in the phase present with peaks of cerium dioxide (CeO2). The thermal analysis of the TiO2 pure and small concentration cerium doped samples show two steps weight loss corresponding to water of hydration and chemisorbed. To larger concentration cerium doped samples were observed two steps weight loss in the transformation of the doped cerium possible intermediate species and SO3. Finally, two steps weight loss the end products CeO2 and SO3 are formed. Analyse electric properties at different temperatures and concentration cerium doped samples have been investigated by impedance spectroscopy. It was observed that titanium, can be substituted by cerium, changing its electric properties, and increased thermal stability of TiO2 anatase structure

Caracterização de látices acrílicos em função da neutralização de seus grupos carboxilas

Latexes based on acrylic acid, acrylamide, ethyl methacrylate, and ethyl acrylate were synthesized via emulsion polymerization with different monomer compositions. The resultant latices were thickened with different molar ratios of NaOH to acrylic acid and were analyzed in terms of acid‐basis titrimetry, turbidimetry, rheology, and tensiometry. Titrimetry, turbidimetry, and rheometry were used to analyze factors such as carboxyl group availability and particle solubilization, tensiometry monitoring the influence of carboxyl neutralization on polymer‐surfactant interactions. For the acrylic acid content used in this work (20 wt%), the results indicated that as carboxyl groups distribution became more homogeneous, the process of latex thickening became more effective

Função quadrática

In general, the study of quadratic functions is based on an excessive amount formulas, all content is approached without justification. Here is the quadratic function and its properties from problems involving quadratic equations and the technique of completing the square. Based on the definitions we will show that the graph of the quadratic function is the parabola and finished our studies finding that several properties of the function can be read from the simple observation of your chart. Thus, we built the whole matter justifying each step, abandoning the use of decorated formulas and valuing the reasoning

Estimativa de espessura crustal na Província Borborema (NE/Brasil) através de função do recpetor

Crustal thickness and VP/VS estimates are essential to the studies of subsurface geological structures and also to the understanding of the regional tectonic evolution of a given area. In this dissertation, we use the Langston´s (1979) Receiver Function Method using teleseismic events reaching the seismographic station with angles close to the vertical. In this method, the information of the geologic structures close to the station is isolated so that effects related to the instrument response and source mechanics are not present. The resulting time series obtained after the deconvolution between horizontal components contains the larger amplitude referring to the P arrival, followed by smaller arrival caused by the reverberation and conversion of the P-wave at the base of the crust. We also used the HK-Stacking after Zhu & Kanamori (2000) to obtain crustal thickness and Vp/VS estimates. This method works stacking receiver functions so that the best estimates of crustal thickness and Vp/VS are found when the direct P, the Ps wave and the first multiple are coherently stacked. We used five broadband seismographic stations distributed over the Borborema Province, NE Brazil. Crustal thickness and Vp/VS estimates are consistent with the crust-mantle interface obtained using gravity data. We also identified crutal thickening in the NW portion of the province, close to Sobral/CE. Towards the center-north portion of the province, there is an evident crustal thinning which coincides with a geological feature consisting of an alignment of sedimentary basins known as the Cariris-Potiguar trend. Towards the NE portion of the province, in Solânea/PB and Agrestina/PE regions, occurs a crustal thickening and a systematic increase in the VP/VS values which suggest the presence of mafic rocks in the lower crust also consistent with the hypothesis of underplating in the region
