This is the essential time for maternal psychosocial adaptation, in which there is the intense transformation of a life without offspring into a life with one or more children. The Pregnancy Self-Evaluation Questionnaire (PSEQ) has 79 items, subdivided into seven subcategories: acceptance of pregnancy, identification with the maternal role, well-being of mother and baby, preparing for labor, control in labor, relationship with the mother and the relationship with the partner. Objective: To translate and cross-culturally adapt the instrument PSEQ to be used with Brazilian women. Methods: It is a cross-sectional observational study. We followed some methodological steps to achieve the cross-cultural adaptation of this measuring instrument. They are: translation, synthesis, back translation, analysis of the committee of specialists and pre-test. Another questionnaire was applied to characterize the socio-demographic and clinical status of the pregnant women (n = 36). The descriptive statistics was gotten through the average, standard deviation (SD), absolute and relative frequency. The statistical test used for the analysis of the internal consistency was Cronbach's alpha coefficient, using SPSS version 17.0. Results: The volunteers had low socioeconomic status, average age of 25.1 years (? 5.52), and average gestational age of 25.9 weeks (? 8.11). 58.3% of these volunteers had not planned their current pregnancy. The pretest showed that 75% of pregnant women found the questionnaire easy to understand. There was an average of 76.9 (? 3.23) answered items among the participants. Regarding the instrument PSEQ, the identification with the maternal role was the subcategory which showed the highest average 24.8 (? 5.6), while the relationship with the mother had the lowest average 15.4 (? 7.7). The internal consistency ranged from 0.52-0.89. Conclusion: The translation and cross-cultural adaptation of the PSEQ to Portuguese language were carried out with methodological rigor and can be considered an instrument with good internal consistency / Introdu??o: O per?odo gestacional humano normal tem dura??o de 40 semanas, tempo essencial para a adapta??o psicossocial materna, no qual acontece a intensa transforma??o de uma vida sem filho para uma vida com filho ou com mais um filho. O Pregnancy Self-Evaluation Questionnaire (PSEQ) possui 79 itens, sendo subdividido em sete sub-escalas: aceita??o da gravidez, identifica??o com o papel materno, bemestar da m?e e do beb?, prepara??o para o trabalho de parto, controle no trabalho de parto, relacionamento com a m?e e relacionamento com o companheiro. Objetivo: Traduzir e adaptar transculturalmente o instrumento PSEQ para ser usado em gestantes brasileiras. M?todos: Estudo observacional de corte transversal. Para a adapta??o transcultural desse instrumento de medida foram seguidas as seguintes etapas metodol?gicas: tradu??o, s?ntese, back translation, an?lise do comit? de especialistas e pr?-teste. Para caracteriza??o s?cio-demogr?fica e cl?nica das gestantes (n=36), outro question?rio foi aplicado. A estat?stica descritiva foi feita atrav?s da m?dia, desvio padr?o (Dp), freq??ncia absoluta e relativa. O teste estat?stico usado para an?lise da consist?ncia interna foi o coeficiente alfa de Cronbach, por meio do SPSS vers?o 17.0. Resultados: As volunt?rias apresentaram baixo n?vel s?cio-econ?mico, m?dia de idade de 25,1 anos (? 5,52), idade gestacional m?dia de 25,9 semanas (? 8,11). Destas, 58,3% n?o haviam planejado a atual gravidez. O pr?-teste mostrou que 75% das gestantes consideraram o question?rio de f?cil entendimento. Houve uma m?dia de 76,9 (?3,23) itens respondidos entre as participantes. Quanto ao instrumento PSEQ, a identifica??o com o papel materno foi a sub-escala que apresentou maior m?dia 24,8 (?5.6), enquanto o relacionamento com a m?e apresentou a menor m?dia 15,4 (?7.7). A consist?ncia interna variou entre 0.52-0.89. Conclus?o: A tradu??o e adapta??o transcultural do PSEQ para o portugu?s foram realizadas com rigor metodol?gico, mostrando ser um instrumento com boa consist?ncia interna

However, there are still no studies that provide predictive equations and reference values for maximal respiratory pressures for children in our population. Aim: The purpose of this study was to propose predictive equations for maximal respiratory pressures in healthy school children. Method: This is an observational cross-sectional study. 144 healthy children were assessed. They were students from public and private schools in the city of Natal /RN (63 boys and 81 girls), subdivided in age groups of 7-8 and 9-11 years. The students presented the BMI, for age and sex, between 5 and 85 percentile. Maximal respiratory pressures were measured with the digital manometer MVD300 (Globalmed ?). The maximal inspiratory pressure (MIP) and maximal expiratory pressures (MEP) were measured from residual volume and total lung capacity, respectively. The data were analyzed using the SPSS Statistics 15.0 software (Statistical Package for Social Science) by assigning the significance level of 5%. Descriptive analysis was expressed as mean and standard deviation. T'Student test was used for unpaired comparison of averages of the variables. The comparison of measurements obtained with the predicted values in previous studies was performed using the paired t'Student test. The Pearson correlation test was used to verify the correlation of MRP's with the independent variables (age, sex, weight and height). For the equations analysis the stepwise linear regression was used. Results: By analyzing the data, we observed that in the age range studied MIP was significantly higher in boys. The MEP did not differ between boys and girls aged 7 to 8 years, the reverse occurred in the age between 9 and 11 years. The boys had a significant increase in respiratory muscle strength with advancing age. Regardless sex and age, MEP was always higher than the MIP. The reference values found in this study are similar to a sample of Spanish and Canadian children. The two models proposed in previous studies with children from other countries were not able to consistently predict the values observed in this studied population. The variables sex, age and weight correlated with MIP, whereas the MEP was also correlated with height. However, in the regression models proposed in this study, only gender and age were kept exerting influence on the variability of maximal inspiratory and expiratory pressures. Conclusion: This study provides reference values, lower limits of normality and proposes two models that allow predicting, through the independent variables, sex and age, the value of maximal static respiratory pressures in healthy children aged between 7 and 11 years old / I ntrodu??o: A avalia??o da for?a muscular respirat?ria ? importante no diagn?stico e acompanhamento de fraqueza muscular em doen?as respirat?rias e neuromusculares. No entanto, ainda inexistem estudos que disponibilizem equa??es preditivas e valores de refer?ncia para as press?es respirat?rias m?ximas para crian?as na popula??o brasileira. Objetivo: O prop?sito desse estudo foi propor equa??es preditivas para as press?es respirat?rias m?ximas de crian?as brasileiras. M?todo: Trata-se de um estudo observacional do tipo transversal. Foram avaliadas 144 crian?as saud?veis, estudantes da rede p?blica e privada do munic?pio do Natal/RN (63 meninos e 81 meninas), subdividas nas faixas et?rias de 7 a 8 e 9 a 11 anos. Os escolares apresentavam o IMC, para a idade e o sexo, entre o percentil 5 e 85. As press?es respirat?rias m?ximas foram mensuradas com o manovacu?metro digital MVD300 (Globalmed?). As press?es inspirat?rias m?ximas (PIm?x) e as press?es expirat?rias m?ximas (PEm?x) foram medidas a partir do volume residual e da capacidade pulmonar total, respectivamente. Os dados foram analisados atrav?s do software Statistics SPSS 15.0 (Statistical Package for the Social Science) atribuindo-se o n?vel de signific?ncia de 5%. A an?lise descritiva foi expressa atrav?s de m?dia e desvio padr?o. Foi utilizado o teste t Student n?o pareado para a compara??o de m?dias das vari?veis. A compara??o das m?dias obtidas com os valores preditos em estudos pr?vios foi feita atrav?s do teste t Student pareado. O teste de correla??o de Pearson foi utilizado para verificar a exist?ncia de correla??o das PRM com as vari?veis independentes (idade, sexo, peso e altura). Para obter as equa??es preditivas foi utilizada a an?lise de regress?o linear m?ltipla stepwise. Resultados: Ao analisar os dados, observou-se que nas faixas et?rias avaliadas a PIm?x foi significativamente superior nos meninos. A PEm?x n?o diferiu entre meninos e meninas de 7 a 8 anos, o inverso ocorreu na faixa compreendida entre 9 e 11 anos. Os meninos apresentaram incremento significativo da for?a muscular respirat?ria com o avan?ar da idade. Independentemente do sexo e da faixa et?ria a PEm?x foi sempre superior ? PIm?x. Os valores de refer?ncia encontrados neste estudo s?o similares aos de uma amostra de crian?as espanholas e canadenses, no entanto subestimaram os valores das medidas encontradas em outra amostra de crian?as canadenses. As equa??es propostas em dois estudos realizados anteriormente, com crian?as de outros pa?ses, n?o foram capazes de predizer consistentemente os valores observados neste estudo. As vari?veis sexo, idade e peso apresentaram correla??o com a PIm?x, enquanto que a PEm?x tamb?m apresentou correla??o com a altura. No entanto, nos modelos de regress?o propostos neste estudo, apenas o sexo e a idade permaneceram exercendo influ?ncia sobre a variabilidade das press?es inspirat?ria e expirat?ria m?ximas. Conclus?o: O presente estudo disponibiliza valores de refer?ncia, limites inferiores de normalidade e prop?e dois modelos de equa??o que permitem predizer, atrav?s das vari?veis independentes sexo e idade, o valor das press?es respirat?rias est?ticas m?ximas de crian?as brasileiras com idade entre 7 e 11 anos

Such changes affects more than half of the adults above 65 years old, that live in the community and 70% of the institutionalized, a great negative impact in their quality of life. One of the pathological displays of aging, that share some characteristics with sleeping disorders and predict similar results, is the Frailty Syndrome, that characterize the most weakened and vulnerable elderly. The way sleeping disorders play a role in the frailty pathogeneses remains uncertain. Objective: Evaluate the relation between the sleeping and the frailty syndrome on institutionalized elderly. Methodology: A transversal study was performed with 69 elderly in institutions in the city of Jo?o Pessoa PB. Were used the Pittsburgh Sleeping Quality Index and actigraphy to subjective and objective variables, respectively, and questionnaires and specific tests to frailty phenotype variant (Fried Frailty Criteria). In the statistic analysis were used the Pearson correlation test, Chi Square and One-way ANOVA test, with Tukey-Krammer posttest. Subsequently, a Simple Linear Regression model was built. On every statistical analysis were considered a confidence interval of 95% and a p < 0,05. Results: The sample was characterized by the prevalence of the frail (49,3%), women (62,3%), single (50,7%) and 77,52 (?7,82).The frail elderly obtained the worst sleeping quality 10,37 (?4,31) (f = 4,15, p = 0,02), when compared with the non-frail. The sleep latency influenced more the frailty (R2 = 0,13, &#946; standard = 1,76, &#946; = 0,41, p = 0,001). Weren t found differences between the standard resting-activity variable and the frailty phenotype categories. Conclusion: Sleeping alterations, including bad sleeping quality, prolonged sleep latency, low sleep efficiency and day drowsiness, influenced the frailty in institutionalized elderly / Introdu??o: O processo de envelhecimento ocasiona modifica??es na quantidade e qualidade do sono. Tais modifica??es afetam mais da metade dos adultos acima de 65 anos de idade, que vivem na comunidade e 70% dos institucionalizados, gerando impacto negativo na sua qualidade de vida. Uma das manifesta??es patol?gicas do envelhecimento que compartilha algumas caracter?sticas com as desordens do sono e prediz resultados similares ? a S?ndrome da Fragilidade, que caracteriza os idosos mais debilitados e vulner?veis. A maneira como os transtornos do sono desempenham um papel na patog?nese da fragilidade permanece incerta. Objetivo: Avaliar a rela??o entre sono e s?ndrome da fragilidade em idosos institucionalizados. Metodologia: Foi realizado um estudo transversal, com 69 idosos residentes em institui??es no munic?pio de Jo?o Pessoa - PB. Foram utilizados ?ndice de Qualidade de Sono de Pittsburgh e actigrafia para as vari?veis subjetivas e objetivas do sono, respectivamente, e question?rios e testes espec?ficos para as vari?veis do fen?tipo de fragilidade (crit?rios de fragilidade de Fried). Na an?lise estat?stica utilizou-se o teste de correla??o de Pearson, teste Qui Quadrado e ANOVA One-way, com p?steste de Tukey-Kramer. Posteriormente, foi constru?do um modelo de Regress?o Linear Simples. Em toda an?lise estat?stica foi considerado um intervalo de confian?a de 95% e um p < 0,05. Resultados: A amostra foi caracterizada pelo predom?nio de fr?geis (49,3%), mulheres (62,3%), de solteiros (50,7%) e m?dia de idade de 77,52 (?7,82). Os idosos fr?geis obtiveram pior qualidade de sono, 10,37 (?4,31) (f = 4,15, p = 0,02), quando comparados aos n?o fr?geis. A lat?ncia do sono foi a que mais influenciou a fragilidade (R2 = 0,13, &#946; padr?o = 1,76, &#946; = 0,41, p = 0,001). N?o foram encontradas diferen?as entre as vari?veis do padr?o repouso-atividade e as categorias do fen?tipo de fragilidade. Conclus?o: As altera??es do sono, incluindo m? qualidade de sono, lat?ncia de sono prolongada, baixa efici?ncia de sono e sonol?ncia diurna, influenciam a fragilidade em idosos institucionalizados

Studies indicate that the neuroendocrine markers can be related to the appearance of this syndrome. The main endocrine answer to stress is the increase of cortisol levels. Objective: To analyze the correlation between the frailty syndrome the salivary cortisol in elderly residing in nursing homes. Method: A traversal study was accomplished, in Jo?o Pessoa city, PB, with a sample composed by 69 institutionalized elderly. The collected data refer to the frailty phenotype (weight loss, exhaustion, slowness, weakness, and lower level of physical activity) and to salivary cortisol parameters (first measure - 6-7h; second measure - 11-12h; third measure - 16-17h). In the statistical analysis the Pearson s correlation test was used, Chi square Test and Anova and Simple Linear Regression analyses. Results: The sample was composed by 37.7% of men and 62.3% of women, with age average of 77.52 (?7.82). There was a percentile of 45.8% frail elderly. The frail elderly obtained higher cortisol values in the third measure (p=0.04) and the frailty load was significantly associated to the first measure (r=0.25, p=0.04). The simple linear regression analysis presented a determination rate (R2=0.05) between frailty load and first cortisol measure. Conclusion: The largest cortisol values in the morning and before sleeping among the frail elderly supply indications that can have a relationship of cortisol increase levels and the frailty presence in elderly from nursing homes. / Introdu??o: A S?ndrome da fragilidade ? caracterizada pela diminui??o da reserva de energia e pela resist?ncia reduzida aos estressores. Estudos indicam que os marcadores neuroend?crinos podem estar relacionados ao surgimento desta s?ndrome. A principal resposta end?crina ao estresse ? o aumento dos n?veis de cortisol. Objetivo: Analisar a correla??o entre a s?ndrome da fragilidade e o cortisol salivar em idosos residentes em institui??es de longa perman?ncia. M?todo: Foi realizado um estudo transversal, na cidade de Jo?o Pessoa-PB, com uma amostra composta de 69 idosos institucionalizados. Os dados coletados referem-se ao fen?tipo de fragilidade (perda de peso, fadiga, lentid?o fraqueza, e baixo n?vel de atividade f?sica) e aos par?metros do cortisol salivar (primeira medida 6-7h; segunda medida 11-12h; terceira medida- 16-17h). Na an?lise estat?stica utilizou-se o teste de correla??o de Pearson, Teste Qui quadrado e Anova. Posteriormente a an?lise de Regress?o Linear simples. Resultados: A amostra foi composta de 37,7% de homens e 62,3% de mulheres, com m?dia de idade de 77,52 (?7,82). Houve um percentual de 45,8% de idosos fr?geis. Os idosos fr?geis obtiveram maiores valores de cortisol na terceira medida (p=0,04) e a carga de fragilidade esteve associada significativamente ? primeira medida (r=0,25, p=0,04). A an?lise de regress?o linear simples apresentou uma taxa de determina??o (R2=0,05), entre carga de fragilidade e primeira medida de cortisol. Conclus?o: Os maiores valores de cortisol pela manh? e antes de dormir entre os idosos fr?geis fornecem ind?cios de que possa haver uma correla??o positiva entre os n?veis de cortisol e a fragilidade em idosos de institui??es de longa perman?ncia.

Methods: Sixty-four volunteers, of both genders, with an average of 21,8 ? 1,7 years and mean body mass index of 24,2 ? 3,7 Kg/m2 were randomly assigned into 4 groups: control group (was not induced fatigue); Experimental Group 1 (Exp. 1 1 minute of rest after fatigue); Experimental Group 3 (Exp. 3 3 minutes of rest after fatigue) and Experimental Group 5 (Exp. 5 5 minutes of rest after fatigue). The subjects were evaluated to the knee?s joint position sense (JPS), followed by 5 flexion-extension knee concentric isokinetic contractions at 60?/s, with concomitant recording of median frequency (Fmed) of rectus femoris (RF), vastus lateralis (VL) and vastus medialis (VM). Then they underwent a muscle fatigue protocol (30 flexion-extension knee concentric contractions at 60?/s) and were reevaluated on the isokinetic performance, Fmed and JPS. Blood lactate levels were measured before initial assessment, immediately after the fatigue protocol and 5 minutes after the end of the rest period. Results: The adoption of 3 minutes of rest was sufficient to restore the initial conditions for the peak torque normalized by body weight and the VL and VM Fmed. The joint position sense returned to its initial values with 1 minute rest. The lactate concentration remained high regardless of the adopted rest period. Conclusion: The use of 3-minute rest period is sufficient for the reestablishment of the neuromuscular parameters to the pre fatigue values. / Objetivo: Avaliar o efeito de diferentes tempos de repouso, ap?s fadiga muscular induzida, no desempenho neuromuscular do quadr?ceps femoral, em indiv?duos saud?veis. M?todos: Sessenta e quatro volunt?rios, de ambos os g?neros, com m?dia de 21,8 ? 1,7 anos e ?ndice de massa corp?rea m?dio de 24,2 ? 3,7 Kg/m2 foram distribu?dos aleatoriamente em 4 grupos: Grupo Controle (n?o foi induzida fadiga); Grupo Experimental 1 (Exp. 1 1 minuto de repouso ap?s fadiga); Grupo Experimental 3 (Exp. 3 3 minutos de repouso ap?s fadiga); e Grupo Experimental 5 (Exp. 5 5 minutos de repouso ap?s fadiga). Os sujeitos realizaram uma avalia??o que consistiu na determina??o do senso de posi??o articular (SPA) do joelho, seguida de 5 contra??es isocin?ticas conc?ntricas de flexo-extens?o do joelho a 60?/s, com concomitante registro da frequ?ncia mediana (Fmed) dos m?sculos reto femoral (RF), vasto lateral (VL) e vasto medial (VM). Em seguida, foram submetidos a um protocolo de fadiga muscular (30 contra??es conc?ntricas de flexo-extens?o do joelho a 60?/s) e reavaliados quanto ao desempenho isocin?tico, Fmed e SPA. Os n?veis de lactato sangu?neo foram mensurados antes da avalia??o inicial, imediatamente ap?s o protocolo de fadiga e 5 minutos ap?s o t?rmino do tempo de repouso. Resultados: A ado??o de 3 minutos de repouso foi suficiente para restabelecimento das condi??es iniciais para o pico de torque normalizado pelo peso corporal e para a Fmed do VL e VM. O senso de posi??o articular atingiu seus valores iniciais com 1 minuto de repouso. A concentra??o de lactato permaneceu alta independente do repouso adotado. Conclus?o: A ado??o de 3 minutos de repouso ? suficiente para o restabelecimento dos par?metros neuromusculares para os valores pr? fadiga.

Methds: the 12 items MAT-sf went through the process of translation and back translation into Portuguese of the Brazil, considering the semantic and cultural adaptation. In a sample of 150 aged 65-74 years living in the community, the instrument's psychometric properties were evaluated by analysis of convergent and construct validity and test-retest reliability. The main outcomes measures used for validation included in the battery of tests of physical ability, self-repor measures of functional limitations, health, depression, cognitive and sex. The test-retest reliability of the instrument was assessed using the intra-class correlation coefficient (ICC), 40 subjects were reassessed after an interval of 14 days of assessment. Results: the concurrent validity for the MAT-sf was evidenced by significant correlations with SPPB (r = 0,53), number of functional limitations (r = -0,62) and depressive symptoms (r = -0,45). The construct validity of the instrument was measured by gradual and significant increase of the MAT-sf scores with high levels of physical performance and with positive self-reported health, also found that MAT-sf scores were statistically differents according to sex. The variation in MAT-sf scores (R2 = 0,41) was explained by SPPB, number of limitations for activities of daily life and depressive symptoms. High values for test-retest reliability was evidencend by ICC = 0,94, 95% CI = 0,90 0,97. Conclusions: the Brazilian version of the short-form of the Mobility Assessment Tool has values of validity and reliability to ensure its use in elderly populations living in communities / Objetivos: traduzir e avaliar as propriedades psicom?tricas da vers?o brasileira do short-form of the Mobility Assessment Tool (MAT-sf) em idosos comunit?rios brasileiros. M?todos: os 12 itens do MAT-sf passaram pelo processo de tradu??o e retrotradu??o para a l?ngua portuguesa do Brasil, considerando a equival?ncia sem?ntica e adapta??o cultural. Em uma amostra de 150 idosos de 65 a 74 anos residentes em comunidade, as propriedades psicom?tricas do instrumento foram avaliadas atrav?s da an?lise das validades concorrente e de constructo e da confiabilidade teste-reteste. Os principais desfechos utilizados para a valida??o inclu?ram o desempenho na bateria de testes de avalia??o da capacidade f?sica, medidas de auto-relato de limita??es funcionais, de sa?de auto-percebida, sintomatologia depressiva, fun??o cognitiva e sexo. A confiabilidade teste-reteste do instrumento foi avaliada por meio do coeficiente de correla??o intra classe (CIC), para isso, 40 idosos foram reavaliados ap?s um intervalo de 14 dias da avalia??o. Resultados: a validade concorrente para o MAT-sf foi evidenciada por significativas correla??es com o SPPB (r = 0,53), n?mero de limita??es funcionais (r = -0,62) e sintomatologia depressiva (r = -0,45). A validade de constructo do instrumento foi verificada pelo aumento significativo e gradual dos escores do MAT-sf com altos n?veis de desempenho f?sico e relato de boa sa?de auto percebida, al?m disso, observou-se que os escores do MAT-sf foram estatisticamente diferentes de acordo com o sexo. A varia??o dos escores do MAT-sf (R2= 0,41) foi explicada pelos escores do SPPB, n?mero de limita??es para atividades da vida di?ria e sintomatologia depressiva.

This large discrepancy can be attributed to the different methodologies proposed. Although the importance of MRP is widely recognized, there are no Brazilian studies that provide predictive equations and reference values for PRM adolescents. Objectives: The purpose of this study was to provide normal values and propose predictive equations for maximal static respiratory pressures of Brazilian adolescents. Methods: An observational cross-sectional study, which evaluated 182 adolescents of both sexes aged between 12 and 18 years, enrolled in schools of the state and private in the city of Natal / RN. The selection of schools and participants of the study was randomly through a lottery system. The spirometric evaluation was performed through the digital spirometer One Flow FVC prior to the assessment of respiratory muscle strength. The MICs were measured with MVD digital manometer 300. Statistical analysis was performed using the SPSS 17.0 software STATISTICS, assigning the significance level of 5%. The normality of data distribution was verified using the Kolmogorov-Smirnov (KS). The descriptive analysis was expressed as mean and standard deviation. We used one-way ANOVA test to verify the difference of the averages of MRPs between age and gender and comparing the averages of MRPs between levels of physical activity. The test t'Student unpaired compared the averages of MRPs being ages and sexes. The comparison of mean values obtained in this study PRM with the values predicted using the equations mentioned above was relizada by testing paired t'Student. To verify the correlation between the PRM and the independent variables (age, weight, height) was used Pearson correlation test. Levene's test evaluated the homogeneity of variance. To obtain predictive equations analysis was used stepwise multiple linear regression. Results: There was no significant difference in mean age between the PRM. The male adolescents, regardless of age, showed superiority in MRP values when compared to the opposite sex. Weight, height and sex correlated with the PRM. Regression analysis suggested in this study, pointed out that the weight and sex had an influence in MIP and MEP only in relation to sex influenced. The mean for each PRM adolescents classified as very active were superior to those observed in adolescents classified as irregularly active. Conclusion: This study provides reference values and two models of predictive equations for maximal inspiratory and expiratory pressures, and to establish the lower limits of normality that will serve as an indispensable condition for careful evaluation of respiratory muscle strength in Brazilian adolescents / Introdu??o: Os valores de refer?ncia e as equa??es preditivas para as press?es respirat?rias m?ximas (PRM) diferem significativamente entre os estudos dispon?veis. Esta grande discrep?ncia pode ser atribu?da ?s distintas metodologias propostas. Embora a import?ncia das PRM seja amplamente reconhecida, inexistem estudos brasileiros que disponibilizem equa??es preditivas e valores de refer?ncia para as PRM de adolescentes. Objetivos: O prop?sito deste estudo foi disponibilizar valores de normalidade e propor equa??es preditivas para as press?es respirat?rias est?ticas m?ximas de adolescentes brasileiros. M?todos: Estudo observacional do tipo transversal, que avaliou 182 adolescentes, de ambos os sexos com faixa et?ria entre 12 e 18 anos, matriculados em escolas da rede estadual e privada do munic?pio do Natal/RN. A sele??o das escolas e dos participantes do estudo foi realizada de maneira aleat?ria atrav?s de sorteios. A avalia??o espirom?trica foi realizada, atrav?s do espir?metro digital One Flow FVC, previamente ? avalia??o da for?a dos m?sculos respirat?rios. As PRM foram medidas com o manovacu?metro digital MVD300 da Globalmed ?. A an?lise estat?stica foi feita atrav?s do software estat?stic SPSS 17.0, atribuindo-se o n?vel de signific?ncia de 5%. A normalidade de distribui??o dos dados foi verificada por meio do teste de Kolmogorov-Smirnov (KS). A an?lise descritiva foi expressa em m?dias e desvio padr?o. Foi utilizado o teste ANOVA one way para verificar a diferen?a das m?dias das PRM entre a idade e o sexo e comparar as m?dias das PRM entre os n?veis de atividade f?sica. O teste t Student n?o pareado comparou as m?dias das PRM ente as idades e os sexos. A compara??o das m?dias dos valores de PRM obtidas no atual estudo com os valores preditos por meio das equa??es propostas anteriormente foi relizada atrav?s do teste t Student pareado. Para verificar a correla??o entre as PRM e as vari?veis independentes (idade, peso, altura), foi utilizado o teste de correla??o de Pearson. O teste de Levene avaliou a homogeneidade de vari?ncia. Para a obten??o das equa??es preditivas foi utilizada a an?lise de regress?o linear m?ltipla stepwise. Resultados: Foi observada inexist?ncia de diferen?a significativa nas m?dias das PRM entre as idades. Os adolescentes do g?nero masculino, independentemente da idade, apresentaram superioridade nos valores das PRM quando comparados ao sexo oposto. As vari?veis peso, altura e sexo apresentaram correla??o com as PRM. A an?lise de regress?o proposta neste estudo, apontou que o peso e o sexo exerceram influ?ncia na PIm?x e em rela??o a PEm?x apenas o sexo a influenciou. As m?dias obtidas para as PRM dos adolescentes classificados como Muito Ativo apresentaram superioridade ?s observadas nos adolescentes classificados como Irregularmente Ativo. Conclus?o: O presente estudo disponibiliza valores de refer?ncia e dois modelos de equa??es preditivas para as press?es inspirat?ria e expirat?ria m?ximas, al?m de estabelecer os limites inferiores de normalidade que servir?o como par?metros indispens?veis ? avalia??o criteriosa da for?a muscular respirat?ria de adolescentes brasileiros

Despite the fact that the main sleep disorders in stroke patients are well known, it is still necessary to analyze which mechanisms of regulation of sleep and wakefulness are affected. The objective of this study was to evaluate the changes in the circadian and homeostatic control of sleep-wakefulness in stroke patients and the correlations with quality of life and level of physical activity. The study analyzed 22 stroke patients (55? 12 years old) and 24 healthy subjects (57 ?11 years old). The instruments used in this study were questionnaires on sleep quality, daytime sleepiness, quality of life, physical activity level and the actigraphy. The data were analyzed using the Student `t test, Mann-Whitney test, ANOVA and Spearman's correlation tests. The results showed stability in the sleep-wake circadian expression with changes in the amplitude of the rhythm. However, significant changes were found related to the homeostatic component characterized by increased sleep duration, increased latency, fragmented sleep and lower sleep efficiency. Additional data showed decreased quality of sleep and increased daytime sleepiness, as well as decreased quality of life and level of physical activity. The results indicate that the interaction of circadian and homeostatic control of sleep-wake is compromised and the main reason might be because of the homeostatic component and the lower activity level resulting from the brain damage. Thus, further studies may be developed to evaluate whether behavioral interventions such as increased daytime activity and restriction of sleep during the day can influence the homeostatic process and its relation to circadian component, resulting in improved quality of nocturnal sleep in stroke patients / O Acidente Vascular Encef?lico (AVE) ? uma disfun??o neurol?gica de origem vascular com desenvolvimento de d?ficits sens?riomotores, cognitivo, perceptivo e da linguagem. Apesar de serem conhecidas as principais altera??es do sono nos pacientes com AVE, ainda ? necess?rio analisar quais mecanismos da regula??o do sono e vig?lia est?o afetados. O objetivo deste estudo foi avaliar as altera??es do controle circadiano e homeost?tico do sono-vig?lia em pacientes com AVE e as correla??es com a qualidade de vida e o n?vel de atividade f?sica. Participaram do estudo 22 pacientes (55?12 anos) e 24 sujeitos saud?veis (57?11 anos). Os instrumentos utilizados neste estudo foram os question?rios sobre a qualidade do sono, sonol?ncia diurna, qualidade de vida, n?vel de atividade f?sica e a actimetria. Os dados foram analisados atrav?s do teste t`Student, teste de Mann-Whitney, ANOVA e teste de correla??o de Spearman. Os resultados encontrados no estudo apontaram estabilidade da express?o circadiana do sono-vil?gia com altera??o na amplitude do ritmo. Entretanto, foram encontradas altera??es homeost?ticas significativas relacionadas com maior dura??o do sono, lat?ncia e fragmenta??o do sono, assim como menor efic?ncia. Dados adicionais mostraram comprometimento da qualidade do sono e aumento da sonol?ncia diurna, assim como diminui??o da qualidade de vida e do n?vel de atividade f?sica. Os resultados observados indicam comprometimento da intera??o do controle circadiano e homeost?tico do sono-vig?lia desencadeado principalmente pelo homeost?tico e diminui??o do n?vel de atividade consequentes da les?o cerebral ocorrida. Dessa forma, estudos posteriores podem ser desenvolvidos a fim avaliar se interven??es comportamentais, como aumento da atividade diurna e restri??o do sono durante o dia, podem influenciar o processo homeost?tico e sua rela??o com o circadiano resultando em melhoria da qualidade do sono noturno em pacientes com AVE
