Análise quantitativa e qualitativa do nível de conhecimento dos alunos do curso de fisioterapia sobre a atuação do fisioterapeuta em saúde pública

Fisioterapia é a ciência da saúde que estuda, previne e trata os distúrbios cinéticos funcionais em órgãos e sistemas do corpo humano. O objetivo deste estudo é verificar a expectativa dos alunos do primeiro ao quinto semestre de fisioterapia sobre a atuação do fisioterapeuta em saúde pública e a expectativa desses alunos quanto à inserção do profissional de fisioterapia no Programa de Saúde da Família (PSF). Trata-se de estudo realizado na Faculdade Marechal Rondon, com 107 alunos, tendo como critério de exclusão os alunos do sétimo semestre. Foi usado um questionário, contendo onze questões, sendo oito de múltipla escolha e três dissertativas. Os dados passaram por tratamento estatístico, em que foram utilizadas a análise descritiva através do programa Microsoft Excel 2003 e análise do discurso do sujeito coletivo. A respeito da atuação do fisioterapeuta no Sistema Único de Saúde (SUS), 44% dos alunos consideram muito importante, 36% consideraram que o papel do fisioterapeuta no PSF é muito importante, enquanto 24% dos alunos consideram não saber informar quanto à eficácia de seu atendimento. Os alunos consideram importante a atuação do fisioterapeuta no SUS e PSF, mas pouco tem conhecimento sobre a atuação do fisioterapeuta em saúde pública.

Anatomia quantitativa e degradação in vitro de tecidos em cultivares de capim-elefante (Pennisetum purpureum Schumach.)

Neste trabalho quantificaram-se as principais alterações histológicas ocorridas em cultivares de capim-elefante (Pennisetumpurpureum Schumach.), em três estádios de desenvolvimento. A degradação dos tecidos foi avaliada após incubação em líquido ruminal de bovinos. As porcentagens de tecidos presentes em colmo, quilha, limbo e bainha foliares foram determinadas. A quilha e o colmo apresentaram maior proporção de tecido lignificado, enquanto o limbo foliar, maior quantidade de tecido epidérmico e tecido vascular não-lignificado. O tecido parenquimático foi encontrado em menor proporção na bainha foliar, principalmente pela presença do aerênquima, a partir da segunda coleta. A proporção de tecido lignificado aumentou com a maturidade do vegetal, sendo mais acentuado em colmos e limbos. Entre as principais alterações, destaca-se a grande área de degradação encontrada na bainha foliar, mesmo com o envelhecimento dos tecidos. Isto foi associado à presença do aerênquima encontrado nos estádios de desenvolvimento mais avançados. Os estômatos favoreceram a penetração dos microorganismos nos tecidos mais internos da folha (mesofilo). O espessamento e a lignificação da parede celular ocorreram com o envelhecimento das plantas, acompanhado de redução na área de degradação dos tecidos.

Anatomia quantitativa da folha e do colmo de Brachiaria brizantha (Hochst. ex A. Rich.) Stapf e B. humidicola (Rendle) Schweick

As características da digestão das forragens podem ser mais bem compreendidas quando complementadas com estudos de anatomia dos tecidos de plantas forrageiras. Com o objetivo de agregar novas informações ao tema, determinou-se a área dos diversos tecidos presentes na folha e no colmo de Brachiaria brizantha e B. humidicola, em três diferentes níveis de inserção no perfilho. O experimento foi conduzido em casa de vegetação, com plantas mantidas em vasos plásticos contendo areia esterilizada e recebendo solução nutritiva de macro e micronutrientes. Após 70 dias do corte de uniformização das parcelas (vasos), coletou-se o segmento do colmo e da folha (limbo e bainha) situado na porção mediana de cada um dos três diferentes níveis de inserção do perfilho estudado. As amostras foram emblocadas em GMA, seccionadas em micrótomo e o laminário fotomicrografado. As fotografias foram digitalizadas e as áreas de tecidos, mensuradas com software Image Tool. Observou-se que o limbo das folhas basilares apresentou menor área de tecido vascular lignificado. Maior área de tecido parenquimático foi observada na bainha e no colmo da B. brizantha. em relação à B. humidicola, a B. brizantha apresentou maior área de tecido vascular lignificado no limbo, bainha e colmo. Maior distância entre os feixes vasculares foi observada no limbo e na bainha, sendo o número de feixes maior no limbo e no colmo.

Repetibilidade da mensuração de imagens das características de carcaça obtidas por ultrassonografia em fêmeas Nelore

Avaliou-se a repetibilidade da mensuração de imagens de ultrassom da área do músculo longissimus dorsi (AOL) e das espessuras de gordura subcutânea do lombo (EGL) e da garupa (EGG). Imagens de ultrassom tomadas no lombo (entre a 12ª e a 13ª costela) e na garupa (entre os músculos gluteus medium e biceps femoris) de novilhas Nelore de 14 a 22 meses de idade foram classificadas em aceitáveis, marginais e rejeitáveis. As imagens aceitáveis e marginais foram mensuradas duas vezes por três técnicos em diferentes níveis de treinamento. Foram estimadas as repetibilidades entre e dentro de técnicos por classe de qualidade da imagem, para determinação do efeito da qualidade da imagem e do técnico no valor absoluto da diferença entre a primeira e a segunda mensuração dessas características. A repetibilidade para as imagens aceitáveis foi maior que para imagens marginais, tanto entre como dentro de técnicos. Na análise da diferença absoluta entre a primeira e a segunda interpretação, foram significativos os efeitos de técnico para AOL e EGL e de classe de qualidade da imagem para AOL. em geral, o técnico com maior experiência apresentou maiores valores de repetibilidade. É recomendável que a mensuração de imagens de animais de mesmo grupo contemporâneo seja feita por um único técnico.

Abordagem quantitativa na avaliacao do deposito de carvao de cerquilho - SP

This paper deals with an integrated study concerning the evaluation of the coal deposit at Cerquilho (Sao Paulo State) in the upper part of the Tubarao Group. Palaeogeographical studies from other authors describe the genesis of these deposits as a deltaic system overlapped by a marine transgressive sequence. The study applied four methods for ore reserve estimation (isolines, blocks, polygones and triangles), besides statistical and geostatistical methodology. The technological characterization assays suggest the application for the coal in cement and ceramics industries. The applied methodology showed reserves estimated around 1 400 000 ton. The isolines method tend to underestimate the amount of coal, on the other hand, the kriging method shows a tendency to overestimate the results. The data from the polygonal method are closest to mean values. For the thickness estimation the results close to the mean values are those from the isolines. -after English summary

Uso da restrição alimentar quantitativa para diminuir a mortalidade de frangos de corte machos

The effect of feed restriction (0, 10, 20, 30, 40 and 50%) from 8 until 14 days post-hatching on performance, total mortality incidence and sudden death syndrome (SDS) rate was studied in male broilers during winter and summer.Ad libitum fed broilers had a better performance, but a higher total mortality rate (13.00% in winter, 3.67% in summer) and SDS (3.67% in winter, 0.67% in summer). All restricted groups had a lower mortality level in winter than the control group with a non linear response influenced by feed restriction. Birds submitted to 40% feed restriction showed the lowest mortality incidence (2.67%) followed by groups submitted to 30% (4.67%), 50% (5.33%) and 10% and 20% (7.67%) feed restriction. Birds fed ad libitum had the highest SDS incidence (3.67%, against .33, 1.00, .67, 1.33 and 1.33% at 10, 20, 30, 40, 50% feed restriction, respectively), but differences were not significant. In summer, incidences of total mortality and due to SDS were low and not influenced by feed restriction, either during the restrictive period itself (8 to 14 days) or during the total period of raising (1 to 49 days). In both seasons, the feed restricted birds showed compensatory gain only until three weeks post-restriction period. At 49 days, body weight and weight-gain were lower in feed restricted birds, but feed :gain ratio rate was improved. This resulted in better productivity index in winter, but not in summer. The feed restriction at 30 to 40% for seven days during the second week may decrease mortality in male broilers raised in winter without lowering productivity if the restriction is followed by at least three weeks of full feeding.

Análise quantitativa de fluoretos nos alginatos para uso odontológico

In this study, the aim was to measure the concentration of fluoride ions in dental alginates and the quantity released from alginate molds immersed in milliQ water, 0.1N hydrochloric acid and artificial saliva. Two separate lots of each of seven brands of alginate commercially available in Brazil were analyzed: Avagel, Deguprint, Hydrogum, Orthoprint, Jeltrate, Jeltrate Plus and Jeltrate Chromatic. Fluoride was measured in each sample by direct potentiometry, using the combined fluoride-ion selective electrode. The brands with the highest fluoride concentrations were Hydrogum (7052.87 μg/g), Jeltrate Plus (6519.68 μg/g) and Orthoprint (6218.18 μg/g). Only in Hydrogum and Jeltrate were different fluoride concentrations found in lots one and two. The various materials showed differences in the amount of fluoride released from the molds into the immersion medium, the mean concentration being highest in Hydrogum and Orthoprint, in all three media. The immersion medium also influenced the release of fluoride, which was lower in saliva than in water and highest in acid. Considering that the concentrations of fluoride found in the alginates tested were high and that various sources of exposure to fluoride exist, there is a need for constant monitoring of alginates intended for dental use.

Validação de método de análise quantitativa para a triancinolona a partir de complexo ternário por espectrofotometria de UV-Vis

Triamcinolone (TRI), a drug widely used in the treatment of ocular inflammatory diseases, is practically insoluble in water, which limits its use in eye drops. Cyclodextrins (CDs) have been used to increase the solubility or dissolution rate of drugs. The purpose of the present study was to validate a UV-Vis spectrophotometric method for quantitative analysis of TRI in inclusion complexes with beta-cyclodextrin (B-CD) associated with triethanolamine (TEA) (ternary complex). The proposed analytical method was validated with respect to the parameters established by the Brazilian regulatory National Agency of Sanitary Monitoring (ANVISA). The analytical measurements of absorbance were made at 242nm, at room temperature, in a 1-cm path-length cuvette. The precision and accuracy studies were performed at five concentration levels (4, 8, 12, 18 and 20μg.mL -1). The B-CD associated with TEA did not provoke any alteration in the photochemical behavior of TRI. The results for the measured analytical parameters showed the success of the method. The standard curve was linear (r2 > 0.999) in the concentration range from 2 to 24 μg.mL -1. The method achieved good precision levels in the inter-day (relative standard deviation-RSD <3.4%) and reproducibility (RSD <3.8%) tests. The accuracy was about 80% and the pH changes introduced in the robustness study did not reveal any relevant interference at any of the studied concentrations. The experimental results demonstrate a simple, rapid and affordable UV-Vis spectrophotometric method that could be applied to the quantitation of TRI in this ternary complex.

Ultrassonografia torácica extracardíaca em pequenos animais

Until recently, ultrasonography was not considered one of the prevailing imaging methods for thoracic evaluation due to its limitations in evaluating lesions located below thoracic gas collections in individuals with normal lung tissue as well as in those with pneumothorax. Nevertheless, ultrasound has an advantage over other imaging techniques. It allows not only differentiating pleural from pulmonary lesions, but also identifying and assessing peripheral pulmonary lesions. Thus, thoracic ultrasound has become more popular in Veterinary Medicine as an ancillary method in the diagnosis and treatment of several diseases of the thoracic cavity, especially in emergency settings. This review aims at providing information on the main alterations found in the chest wall, mediastinum, pleura, lung and diaphragm by means of ultrasonography.

Acurácia da histerossonografia versus ultrassonografia transvaginal em mulheres inférteis candidatas às técnicas de reprodução assistida

PURPOSE: To compare the diagnostic accuracy of sonohysterography (HSN) and conventional transvaginal ultrasound (USG) in assessing the uterine cavity of infertile women candidate to assisted reproduction techniques (ART). METHODS: Comparative cross-sectional study with 120 infertile women candidate to ART, assisted at Centro de Reprodução Assistida (CRA) of Hospital Regional da Asa Sul (HRAS), Brasília-DF, from August 2009 to November 2010. Sonohysterography was performed with saline solution infusion in a close system. The sonohysterography finding was compared to previous USG results. The uterine cavity was considered abnormal whenthe endometrium was found to be thicker than expectedduring the menstrual cycle and whenan endometrial polyp, a submucous myoma and an abnormal shape of the uterine cavity were observed. The statistical analysis was doneusing absolute frequencies, percentage values and the χ 2, with the level of significance set at5%. RESULTS:HSN revealed that 92 (76.7%) infertile women candidate to ARThad anormal uterine cavity, while 28 (23.3%) had the following abnormalities: 15 polyps (12.5%).

Ultrassonografia Doppler na avaliação renal de cadelas diagnosticadas com piometra antes e após tratamento com ovariosalpingohisterectomia

The aim of this study was evaluate the renal hemodynamics of bitches with pyometra by means of laboratory tests, ultrasound B mode and Doppler, before and after treatment with ovariohysterectomy (OSH). This study evaluated 30 bitches with pyometra, all were subjected to OSH (moment 1) and 20 were evaluated after 7 days (moment 2). The renal perfusion, the resistivity index (RI) of the main renal artery and the interlobar arteries (cranial, middle and caudal) were statistically different between times 1 and 2 (p<0,05). There was no statistical difference for renal perfusion between the left and the right kidney at the time 1 and 2. The correlations between the IR of the main artery and the variables used to determine renal function were stablished at the time 1. For the correlated variables: urea, creatinine, proteinuria, ratio GGT/creatinine and protein/creatinine were curvilinear and positive associations with the resistivity index of the main renal artery (p<0,05), however these correlations were considered medium and weak. Comparing the RI of the main renal artery with different scores of dehydration and renal perfusion, there was statistical difference, and show increased of resistance renal in bitches with moderate reduction in renal perfusion as well as in dehydrated bitches. Were evaluated several features of renal morphology in ultrasound B mode, however, only the presence of pelvic dilatation, medullary signal and other changes as infarcts areas and diffuse hyperechoic spots in the renal cortical and medullary were statistically different from one moment to the other, most frequently at the time 2. The results of this study show that the Doppler ultrasound can identify changes of reduction in renal perfusion by color Doppler and the increasing of the resistivity index of the renal arteries in some bitches with pyometra. As well as, the ultrasound B mode, although has non-specific changes, can detect progressive renal disorders in bitches with pyometra.

Ultrassonografia oftálmica em cães com diferentes conformações cranianas

The aim of this study was to establish mean values for intraocular structures and analyse if the differences are present for different skull conformations in dogs. In this study, 30 dogs were selected and distributed into three groups according to skull conformation; thus, group 1 (G1) was composed of brachycephalic dogs, group 2 (G2) was composed of mesocephalic dogs and group 3 (G3) was composed of dolichocephalic dogs. A and B-mode ultrasound was performed simultaneously for obtainment of measurements relating to anterior chamber depth (D1); lens thickness (D2); vitreous chamber depth (D3); and the axial length of the eye (D4). No differences were observed when comparing left and right eyes of dogs within the same skull conformation group (p>0.05). Differences were observed when comparing D3 and D4 between groups G2 and G3 (p<0.05). Skull conformation of brachycephalic dogs did not influence intraocular measurement values when compared to dolicephalic and mesocephalic dogs. Skull conformation of dolichocephalic dogs had an influence in values of vitreous chamber and the complete length of the eye when compared to mesocephalic dogs.
