Mutagênese induzida por flavonóides presentes do decocto das cascas da aroeira (Schinus terebinthifolius, Raddi)

The decoction of Brazilian pepper tree barks (Schinus terebinthifolius, Raddi), is used in medicine as wound healing and antiinflamatory. Once extracts from this plant are used for acceleration of scar s process, it is important to study their mutagenic and genotoxic potential. In previous works in our laboratory, it was observed mutagenicity caused by the decoction when in high concentrations. Among the chemical compounds of this plant that could be able to induce mutation, the flavonoids were the only group that was referred to have either an oxidant or antioxidant potential. The flavonoids were isolated, purified and quantified by adsorptive column chromatography under silica gel, bacterial and in vitro genotoxic tests were realized to determine if the flavonoids were the responsible agents for this mutagenicity found. The tests realized with plasmidial DNA were indicative that the flavonoids are probably genotoxic, due to the presence of correlation between increase of the flavonoid concentration and in plasmidial DNA double strand breakage visualized in agarose gel, as well as they were capable to generated abasic sites shown by the in vitro treatment with exonuclease III. The same tests with plasmidial DNA in the presence of copper [10 µM] and of a Tris-HCl pH 7.5 [10 µM] buffer were realized with the isolated flavonoids to determine if there would be or not participation of reactive oxygen species (ROS). The transformation of plasmidial DNA in different bacterial strains proficient and deficient in DNA repair enzymes in the presence or not of a Tris-HCl buffer, suggests that the enzymes that repair oxidative lesions are necessary to repair the lesions generated by the flavonoids and that ROS are generated and are necessary to promote the lesions. Bacterial tests with Escherichia coli strains of the CC collection (deficient or not for DNA repair enzymes), showed that the flavonoids are able to increase the frequency of mutations, mainly in strains mutated in repair enzymes (MutM, MutY-glicosylases and double mutant), suggesting that these agents are responsible for the enhancement in the mutation rate. In order to determine the mutation spectrum caused by the flavonoids of the Brazilian pepper tree stem bark, plasmidial DNA previously treated with the flavonoids were transformed in bacterial strains deficient and proficient in the DNA repair enzymes, followed by a blue-white selection with X-gal, DNA amplification by PCR and sequencing the positive mutant clones. Analysis of the mutants obtained from strains CC104, CC104mutM, CC104mutY, CC104mutMmutY, BW9101, BW9109 indicated a predominance of some mutations like G:C to C:G that can be correlated with the origin of 8-oxoG, due to oxidative lesions caused by the flavonoids. So it can concluded that the flavonoid isolated or in fractions enriched on them are genotoxic and mutagenic, and their mutations are predominantly oxidative, mediated by ROS, and the lesions are recognized by the BER system. In this way it is proposed that the flavonoids can act in two different ways to generate the DNA lesion: 1. in a Fenton-like reaction, when the flavonoid are in the presence of metal ions and that together with the water generate ROS that promotes the DNA lesions; 2. in another way the lesions can be generated by the formation of ROS due to the internal chemical structure of the flavonoid molecule due to the quantity and location of hydroxyl groups, and so producing the DNA lesions, those lesions can be directly (suggested by the in vitro experiments) or indirectly done (supported by the experiments using the CC bacterial strains)

Voleibol brasileiro : parâmetros fenotípicos e genotípicos na seleção de atletas

Objective: Identify phenotype and genotype parameters of female volleyball players at different performance levels to help in player selection. Methods: We identified characteristics of phenotype and genotype using the somatotype method (Heath Carter); anthropometry (weight, height and fat percentage); dermatoglyphics (Cummins and Midlo s method) as well as applying physical quality tests (Shuttle Run to assess agility and the Sargent Jump Test adapted for spike and block reach). The sample was composed of 179 players (54 from national teams and 125 from state teams). Results: Somatotype was similar among the performance levels in the mesomorphic component. The Height and ectomorphic component were greater in national team players as was spike and block reach. The vertical jump height for the spike was similar between the national under-17 team and the state teams observed, but in the block jump the lower level players were better. The dermatoglyphics characteristics identified were similar among the groups studied. Conclusions: The results of the variables studied show that somatotype, height, spike reach and block reach are fundamental parameters in player selection and in the specific characteristics of each game position of this sport. This paper proposes a multidisciplinary approach applicable in the fields of physical education, medicine and nutrition

Desenvolvimento de Sistemas Microparticulados Superparamagnéticos Gastro-resistentes para Diagnóstico e Terapêutica

This work aimed to develop a suitable magnetic system for administration by the oral route. In addition to that, it was intended to review the current uses of magnetic systems and the safety related to magnetic field exposure. Methods: Coprecipitation and emulsification/crosslinking were carried out in order to synthesize magnetite particles and to coat them, respectively. Results: According to literature review, it was found that magnetic particles present several properties such as magnetophoresis in magnetic field gradient, production of a surrounding magnetic field, and heat generation in alternated magnetic field. When the human organism is exposed to magnetic fields, several interaction mechanisms come into play. However, biological tissues present low magnetic susceptibility. As a result, the effects are not so remarkable. Concerning the development of a magnetic system for oral route, uncoated magnetite particles did undergo significant dissolution at gastric pH. On the other hand, such process was inhibited in the xylan-coated particles. Conclusions: Due to their different properties, magnetic systems have been widely used in biosciences. However, the consequent increased human exposure to magnetic fields has been considered relatively safe. Concerning the experimental work, it was developed a polymer-coated magnetic system. It may be very promising for administration by the oral route for therapy and diagnostic applications as dissolution at gastric pH hardly took place

Prevalência de excesso de peso em pré-escolares na cidade do Natal

Obesity is currently considered a public health problem and there has been growing interest in the study of various aspects related to this infirmity such as: epidemiology, diagnosis, treatment, prevention and others. Thus, the purpose of this study was to determine the prevalence of weight excess and overweight in preschoolers in Natal, Brazil and relate them to variables such as gender, age, type of school (public or private) and zones of the city (east/south and north/west). This is a transversal study, carried out in Natal, Brazil between August and September 2004, in 20 public and 20 private schools/day care centers selected by the systematic sampling method. We measured the weight and height of 3721 students between the ages of 2 and 6 years. The children were stratified, according to age, into age group 1 (2 to 4 years) and age group 2 (5 and 6 years) and according to the region of the school, into north/west and east/south zones, the regions with the smallest and highest quality of life indices in the city, respectively. Children were considered to have weight excess when BMI ≥ 85th percentile, including those with BMI ≥ 95th percentile and overweight when BMI ≥ 95th percentile. The prevalence of weight excess was 26.5%, and of overweight 12.4%. There was greater prevalence of weight excess in the private schools and in the east/south zones. Overweight displayed the same epidemiologic profile, with a greater prevalence in private schools and in the east/south zones. The prevalence of weight excess in preschoolers in Natal, Brazil is high and is related, above all, to private schools and to those located in the highest quality of life areas. Therefore, prevention programs should be implanted in elementary schools in order to decrease weight excess and possible associated co-morbidities. This research project met the norms established by PPGCSa/UFRN and aimed at promoting the interrelation between different researchers and between different fields of knowledge, using multi and interdisciplinary concepts. This study was enriched by the interaction between the following professionals: pediatrician, pediatric gastroenterologist and physician nutrition specialist, pediatric endocrinologist, epidemiologist and biostatistician

Marcadores de risco cardiovasculares bioquímicos e antropométricos em idosos hipertensos e aparentemente saudaveis

Idosos apresentam prevalência aumentada de Hipertensão Arterial Sistêmica - HAS além de multiplicidade de fatores de risco cardiovasculares adicionais relacionados a maus hábitos de vida. Este é um estudo transversal que teve como objetivos comparar e correlacionar marcadores bioquímicos e antropométricos e hábitos de vida indicadores de risco cardiovascular em idosos hipertensos e predominantemente saudáveis, sedentários e praticantes de atividade física. A amostra foi composta por 322 idosos, e distribuída em 2 grupos: G1: hipertensos e G2: predominatemente saudáveis. A coleta de dados constou de anamnese e avaliações bioquímica (perfil lipídico e Proteína C-Reativa - PCR) e antropométrica (Índice de Massa Corpórea - IMC, Circunferência da Cintura - CC, Circunferência abdominal - CA e Relação Cintura- Quadril - RCQ). Na análise dos dados utilizou-se estatística descritiva, Teste t de Student, análise de variância (ANOVA One-Way) e correlação de Pearson. Os resultados mostram que no G1: 100% eram hipertensos, sendo que 31,55% eram diabéticos e hipertensos e 0% era exclusivamente diabético, no G2: 28,86% eram hipertensos, sendo que 13,40% eram diabéticos e hipertensos, 5,15% eram exclusivamente diabéticos e 65,99% não apresentam qualquer processo patológico ativo. Com relação aos hábitos e estilo de vida, no G1: 58,22% eram sedentários; 2,6% fumantes e 1,7% etilistas. No G2: 5,15% eram sedentários; 7,21% fumantes e 8,24% etilistas. Com relação ao estado nutricional, verificou-se que no G1: 10,52% dos homens apresentaram Sobrepeso - SP e 14,03% Obesidade - OB, já entre as mulheres, 25,59% apresentaram SP e 20,23% OB. No G2: 6,06% dos homens apresentaram SP e 9,09% OB, e entre as mulheres, 15,87% apresentaram SP e 22,22% OB. Na análise da RCQ, apresentaram valores acima dos recomendados: 24,56% dos homens e 82,14% das mulheres do G1 e 12,12% dos homens e 74,60% das mulheres do G2. Com relação a CC e CA, apresentaram valores indicativos de risco, respectivamente: no G1 (52,63% e 29,82% dos homens e 91,66% e 87,5% das mulheres) e no G2 (9,09% e 9,09% dos homens, e 80,95% e 55,55% das mulheres). Com relação à idade, as freqüências de SP e OB no G1(n=225) foram: SP (A1=11,11%, A2=8%, A3=1,77%), OB (A1=8,44%, A2=8,88%, A3=1,33%), e no G2(n=97) foram: SP (A1= 5,15%, A2= 5,15%, A3= 2,06%) e OB (A1=9,27%, A2=7,21%, A3=0%). Na comparação entre G1 e G2 observou-se diferença estatísticamente significativa entre as seguintes médias: IMC: [G1=27,23 e G2=23,26 x (p=0,0344)]; CA: [G1=99,09 e G2=89,51 (p<0,0001)]; CC: [G1=93,64 e G2=86,37 (p<0,0001)] e RCQ: [G1=93,64 e G2=86,37 (p<0,0001)]. Na correlação, verificou-se associação considerada como fraca positiva (p<0,05) entre PCR e as variáveis antropométricas e o perfil lipídico. Os resultados apontam para maior freqüência e intensidade de fatores de risco cardiovasculares adicionais a hipertensão em mulheres em relação aos homens, nas faixas etárias relativamente mais jovens, A1 e A2, em relação a mais velha, A3, e no grupo de idosos hipertensos, G1, em relação ao de idosos predominantemente saudáveis, G2. Observou-se correlação, considerada fraca positiva (r>0,30), entre PCR, perfíl lipídico e variáveis antropométrica (p<0,05). Esta tese apresenta uma relação de interface multidisciplinar, tendo o seu conteúdo uma aplicação nos campos da Fisioterapia, Educação Física, Medicina, Nutrição e da Bioquímica

Biodistribuição de samário -153- EDTMP em ratos TRATADOS com docetaxel

A dor óssea decorrente das metástases é um sintoma comum nos tumores avançados de mama e próstata. Nenhuma opção terapêutica isolada é completamente eficaz, e uma série de modalidades costuma ser empregada, entre eles a terapia com radiofármacos, como o samário153-etilenodiaminatetrametileno fosfonato (EDTMP-153Sm). O docetaxel, um taxano com ação sobre tumores avançados de mama e próstata, tem-se apresentado como uma nova opção de tratamento quimioterápico. Muitos pacientes fazem uso simultâneo de EDTMP-153Sm e docetaxel. Este estudo procurou avaliar a influência do docetaxel na biodisponibilidade de EDTMP-153Sm em ratos Wistar, aleatoriamente alocados em 2 grupos de 6 animais cada. O grupo DS (docetaxel/samário) recebeu docetaxel (15 mg/kg) intraperitoneal em dois ciclos com 11 dias de intervalo. Os ratos do grupo S (samário/controle) não foram tratados com docetaxel. Nove dias após a quimioterapia, todos os animais receberam 0.1ml de EDTMP-153Sm via plexo orbital (25μCi). Após 2 horas, os animais foram mortos, e realizaram-se análises de amostras de cérebro, tireóide, pulmão, coração, estômago, cólon, fígado, rim e fêmures. O percentual de radioatividade por grama (%ATI/g) de tecido de cada biópsia foi determinado em contador gama automático (Wizard-1470, Perkin-Elmer, Finland). No 9º dia após 2º ciclo de docetaxel, os ratos tiveram perda de peso significante, passando de 353.66± 22.8g (controle/pré-tratamento) para 314,50±22,09g (p<0.5). Os %ATI/g nos órgãos dos ratos tratados com EDTMP- 153Sm e docetaxel tiveram redução significante nos fêmures direito e esquerdo, rim, fígado e pulmão, quando comparados aos animais não tratados com docetaxel. Em conclusão, a combinação de docetaxel com EDTMP-153Sm foi associada à menor concentração do radiofármaco em órgãos alvo. Futuras investigações sobre o impacto do docetaxel na biodisponibilidade do EDTMP- 153Sm poderão complementar estes achados. Deve-se ressaltar o caráter multidisciplinar deste estudo, que contou com a participação ativa e com a troca constante de conhecimentos entre profissionais das áreas de Medicina Nuclear, Cirurgia, Oncologia, Biologia e Estatística

Voleibol infanto-juvenil brasileiro: Somatotipia, qualidades físicas e marcadores genéticos dos atletas em diferentes níveis de qualificação esportiva

The elaboration of profiles with characteristics that can be parameters in the different categories of sports modalities and the investment in scientific studies have revealed a significant importance in the development of new generations of athletes. Based in the exposed, the purpose of this study was to identify and compare the somatotype characteristics, physical qualities and genetic markers of Brazilian male volleyball players in the 14-17 category playing at different levels (international, national and regional). We used a scale, stadiometer, pachymeter, and adipometer to evaluate somatotype, attack and block reach test, medicine ball toss, 30-meter agility test , the AAHPER -30 test to evaluate basic physical qualities and the dermatoglyphic method to identify genetic markers. The results show the superiority of the national team over the other squads in the somatotype component (ectomorphy), and in the level of basic physical qualities. We found no significant difference in genetic markers among the teams studied. We conclude that Brazilian volleyball players at different performance levels have characteristics peculiar to the sport, with height and physical qualities being significantly different among these teams. The results confirm de necessity of knowing the athletes specific characteristics when dealing with high performance teams using nutrition, medicine, physiology and genetics specific knowledges to achieve a better sportive development

Biodistribuição do pertecnetato de sódio após desvio gástrico em Y de Roux (técnica de capella)

O desvio gástrico em Y de Roux é a técnica cirúrgica mais utilizada no tratamento da obesidade mórbida. Esta operação reduz o volume do estômago e o comprimento do intestino delgado, gerando alterações estruturais e metabólicas que podem influenciar no resultado de exames cintilográficos de pacientes operados. Com o objetivo de avaliar a biodistribuição pós-operatória do pertecnetato de sódio (Na99mTc) em órgãos de ratos Wistar submetidos à técnica do bypass (desvio) gástrico em Y de Roux (BGYR), foram utilizados 12 ratos distribuídos aleatoriamente em grupo tratado (n=6), submetido à cirurgia do BGYR e o grupo controle (C; n=6). No 15º dia de pós-operatório foi administrado 0,1 mL via plexo orbital de Na99mTc aos animais dos dois grupos, com atividade radioativa média de 0,66MBq. Após 30 minutos, os ratos foram mortos e retirados fragmentos de tireóide, coração, pulmão, fígado, estômago, rim e fêmur. As amostras foram lavadas com solução salina 0,9%, pesadas e submetidas ao Contador Gama 1470, WizardTM Perkin-Elmer-Finlândia para determinação do percentual de atividade radioativa total por grama (%ATI/g) de cada órgão. Empregou-se o teste t de Student para análise estatística, considerando-se significantes as diferenças das médias quando p<0,05. Redução significante na média de %ATI/g foi observada no fígado, estômago e fêmur dos animais submetidos à cirurgia de BGYR comparada ao grupo controle (p<0,05). Nos demais órgãos não houve diferença estatisticamente significativa entre os grupos. Em conclusão, a cirurgia BGYR em ratos modificou a biodistribuição do Na99mTc em alguns órgãos, podendo ter implicações clínicas na interpretação de exames cintilográficos. Este estudo xi teve um caráter multidisciplinar com a participação de pesquisadores das áreas de Cirurgia Experimental, Farmácia, Radiobiologia, Medicina Nuclear e Estatística

Imagem corporal e fatores de risco em praticantes de caminhada da cidade do Natal-RN

Body image is the figure of our bodies built in our minds and the degree of dissatisfaction is often associated with risk factors identified by anthropometric measures. The purpose of this descriptive study was to evaluate the risk factors associated to morphological and functional variables associate to the perception of auto-image in middle-aged walkers of the south zone of the city of Natal. A hundred and thirty volunteers had been evaluated in four groups in function of the gender and age group. As measurement evaluations were used an auto-image perception questionnaire proposed by Stunkart of nine silhouettes numbered for both gender was applied; a weighing machine equipped with stadiometer for the body mass (kg) and stature (m) and the body mass index (kg/m2) that was calculated with base in measures of the body weight and stature and classified according to norms of the National Institute of Health (2000) as well as the systolic and diastolic blood pressure by a electronic digital device (DIGITRONIC). A metal anthropometric tape was used for the waist to hip ratio (WHR). It was used Analyses of variance (ANOVA) one-way, post hoc of Tukey and correlation of Spearman for the nonparametric data adopting the level of ρ≤ 0,05 for rejection of the null hypothesis. The body mass index indicated high factors of risk in the consisting groups. In all the groups were registered the desire to reduce their silhouettes. The body weight shows reduced when compared with the younger group in the male group of superior age group, while in the female group the inverse one occurs. The autoimage perception is associated with the classification of the waist to hip ratio in the female gender in the age group of the 50 to the 59 years and in the classification of the body mass index of all constituted groups. Significant associations had not been found for classification of the systolic and diastolic blood pressure in relation to the auto-image 41 perception. This thesis presents relation of interdisciplinarity and its contents have application in the fields of Physical Education, Medicine, Physiotherapy and Nursing

Excesso de peso em região do nordeste brasileiro: contraste entre escolares de rede pública e privada de ensino

The prevalence of obesity has been increased in the last three decades. It is already considered as epidemic by the World Health Organization and reaches around 300 million people worldwide. The weight gain in all ages is related to a sedentary way of life and hyper caloric food ingestion at the modern society. Obesity is a chronic disease and leads to high blood pressure, diabetes, cardiovascular diseases and cancer. The aim of this study was to evaluate the prevalence of weight excess among student in Natal schools and to analyze its association with age, gender, school category and geographic localization in city zones. This was a transversal study which enrolled 1927 children. 1084 of these were between 6 and 8 years-old (group 1) and 843 were 9 to 10 years-old (group 2). 895 of the total children studied in private schools and 1032 studied in public schools. 33,6% of the students had body mass index equal or above the 85th percentile and were considered as having weight excess. There was no statistical difference in this prevalence considering neither gender nor age. The weight excess prevalence in private schools was 54,5% and in public ones was 15,6% (p<0,01; OR=6,49). Weight excess was also more prevalent in the south and east city zones (41,3%) which have better quality of life index than in the north and west zones (28,4%) (p<0,01). In conclusion, the weight excess prevalence among students is found to be high in Natal and programs of intervention and prevention of obesity are necessary. The higher prevalence in private schools as in the wealthier city zones reflects the link between obesity and high socioeconomic level found in countries in developing. This was an interdisciplinary work with participation of epidemiology, child nutrition and pediatric endocrinology following the recommendations and principles of the Post graduation Program in Health Sciences of the Federal University of Rio Grande do Norte

Avaliação de efeitos de um extrato aquoso de cinnamomum zeylanicum L. na marcação de constituintes sanguíneos com tecnécio-99m e na morfologia das hemácias de ratos wistar

Radiobiocomplexes are used to obtain images in nuclear medicine and employed in basic research. Blood constituents labeled with technetium-99m (99mTc) have also been employed as radiobiocomplexes and used also experimental model for evaluation of the biological effects of natural or synthetic drugs. The analysis of the morphology and the morphometrics parameters (perimeter/área ratio) can be used to evaluate the effects of drugs upon the structure of the membrane of red blood cells. Cinnamomum zeylanicum (cinnamon) is a spice used as herbal medicine to treat diseases. The aim of this study was to evaluate the effect of in vitro and in vivo treatment with an aqueous cinnamon extract on the labeling of blood constituents with 99mTc and on the morphology of red blood cells from Wistar rats. In the in vitro treatment, isolated blood sample from animals were incubated with cinnamon extract. In the in vivo treatment, blood samples were also withdrawn from animals treated with cinnamon extract. In both cases, the radiolabeling of blood constituents was done. The morphological analysis of red blood cells was also done. As control, blood or animals treated with NaCl 0.9%. The data obtained on the labeling of blood constituents with 99mTc experiments indicated that the in vitro treatment with cinnamon extract was capable to decrease signiicantly (p<0.05) the percentage of radioactivity in cellular compartments and on the fixation of cellular and plasma proteins. These effects were not observed on the in vivo treatment. The results obtained for the morphology of red blood cells suggest that the in vitro and in vivo treatments did not alter the morphology and the perimeter/area ratio. The in vitro treatment with aqueous cinnamon extract could affect the membrane structures related with the oxidation status of the stannous ion pertechnetate ion, altering the labeling of blood constituentes with 99mTc. This study was a multidisciplinary experimental research. It was developed with the contribution of the different Departments and Services of the Hospital Universitário Pedro Ernesto of the Universidade do Estado do Rio de Janeiro

Efeitos de um extrato aquoso de lantana camara (Cambará de espinho) na marcação de constituintes sanguíneos com técnecio-99m e na morfologia de hemácias de ratos-wistar

Medicinal plants have been studied and used in the world. Lantana camara has medicinal properties and it has been used in folk medicine. The aim was to verify the effect of a lantana extract on the labeling of blood constituents with 99mTc, and to evaluate the effect of an aqueous extract of Lantana camara on the morphology of RBC withdrawn from Wistar rats. The results showed that lantana extract has decreased the fixation of radioactivity on the IF-P. This effect was not observed in the BC compartment and in IF-BC. The BC-%ATI was decreased in all concentrations tested when the BC was washed. The osmotic fragility assay and morphological analysis were carried out. In presence of the extract, the data obtained indicated that (i) an increase of the hemolysis and (ii) modifications on the morphology of RBC. These effects of the Lantana camara could be associated with some pharmacological properties of the chemical compounds of this studied extract

Efeito do sildenafil na lesão renal por isquemia-reperfusão em ratos

A lesão renal causada pelo processo isquemia-reperfusão ocorre em várias intervenções cirúrgicas, como transplantes de rins, cirurgias vasculares renais e na nefrectomia parcial. Devido ao processo isquêmico, ocorre disfunção do órgão e morte celular. Com o objetivo de avaliar o efeito do sildenafil, em ratos, administrado previamente à isquemia renal e reperfusão, em avaliações cintilográficas e histopatológicas, foram utilizados vinte e quatro ratos Wistar, aleatoriamente distribuídos em dois grupos. Os animais receberam 0,1 ml IV 99mTecnécio-Etilenodicisteína, realizando-se a cintilografia renal inicial e, em seguida, foram submetidos à laparotomia, provocando-se isquemia no rim esquerdo, com oclusão da artéria renal, durante 1 hora, com posterior reperfusão. Os animais do grupo sildenafil receberam previamente 1mg/kg de sildenafil via oral, 60 minutos antes da isquemia. O grupo controle recebeu somente solução salina. Após a isquemia e reperfusão, metade dos animais de cada grupo foi avaliada com 24 horas e a outra metade, com sete dias, com nova cintilografia renal. Após eutanásia, com superdose de anestésico, os rins foram retirados e submetidos a exame histopatológico. Empregou-se avaliação estatística com o teste t de Student e com teste não-paramétrico de Mann-Whitney. Foi observado no rim esquerdo do grupo controle um déficit funcional nas imagens cintilográficas, após sete dias, comparativamente ao respectivo estudo cintilográfico inicial (p<0,05). Nos rins esquerdos dos animais do grupo controle (24 horas pós-isquemia), ocorreu um maior grau de necrose celular quando comparados ao grupo tratado com o sildenafil (p<0,05). A cintilografia e a histopatologia demonstraram que o sildenafil exerceu ação protetora dos rins, após episódio de isquemia-reperfusão renal normotérmica. Deve ressaltar-se o x caráter interdisciplinar desta tese, que contou com a participação ativa de profissionais das áreas de cirurgia, medicina nuclear, urologia, patologia e estatística

Seleção de categorias da Classificação Internacional de Funcionalidade, Incapacidade e Saúde para avaliação do paciente com acidente vascular cerebral em reabilitação

Stroke represents the first cause of disabilities among adults. Although different professions work together in treatment of stroke patients, all they use different terminologies for the description of the patients problems and it can constitute an impediment in the communication between the staff members. Thus, the multidisciplinary and interdisciplinary work would be facilitated if using a reference common tool, as the new International Classification of Functioning, Disability and Health (ICF). However, the ICF is very extensive and complex and due to its complexity, it has been evidenced the necessity to select its categories to become it more practical. The aim of the study was to investigate which categories of the ICF are more suitable to evaluate and to describe the stroke patient in the view of teachers and municipal public health professionals. It was a descriptive research, which involved 5 professors and 11 professionals of Physiotherapy that have worked at the health public area in Natal / RN. It was used the Delphi Technique in 3 rounds and the Likert Scale to select the categories among the ICF components. As result, from the 362 IFC categories, 94 were selected. The selected categories correspond to rehabilitative characteristics of Stroke patients in the universe of the Physiotherapy performance. The methodology applied was suitable to the studied object emphasizing the necessity of future studies for validation of the chosen categories

Tradução, adaptação e validação da versão brasileira do questionário utian quality of life (uqol) para avaliação da qualidade de vida no climatério

The present study had as objective translates, to do equivalence and validation of the Utian Quality of Life (UQOL) for the Brazilian population through methods internationally accepted, in which the original questionnaire was translated for the Portuguese by three teachers and the consensual version was translated back for English by two American teachers (back translation). A multidisciplinary committee evaluated all versions and the final version in Portuguese was applied to climacteric women for the process of adaptation. Validation of the instrument was performed by measuring the reliability and validity properties. Construct validity was examined through the comparison between UQOL and the general measuring scale of quality of life Short Form-36 (SF-36). The final version of translation process was easily recognized by the target population, that didn't tell understanding problems. The results obtained for the reliability intra and interobserver showed significant agreement in all of the subjects. The construct validity was obtained through correlations statistically significant among the domains occupational, health and emotional of UQOL with the SF-36 domains. For the exploratory factorial analysis, it was verified that three factors explain 60% of the total variance of the data, the present study allowed concluding that UQOL was appropriately translated and adapted for applicability in Brazil, presenting high reliability and validity. In that way, the executed project provided the involvement of different areas as gynecology, psychology and physiotherapy (interdisciplinary). Thus, this instrument can be included and used in Brazilian studies to assessment the quality of life during the climacteric years
