Este estudo teve por objetivo avaliar os fatores associados à disfunção sexual em mulheres de meia idade. Realizou-se um estudo descritivo transversal, que compreendeu 370 mulheres, entre 40 a 65 anos, atendidas nas Unidades Básicas de Saúde de cada distrito sanitário (Norte, Sul, Leste e Oeste) da cidade de Natal, no estado do Rio Grande do Norte, Brasil. Para avaliar a função sexual utilizou-se o Female Sexual Function Index (FSFI). A sintomatologia climatérica foi avaliada por meio do Menopause Rating Scale (MRS). O Índice de Blatt-Kupperman (IMBK) foi utilizado para avaliação quantitativa global da ocorrência de sintomas/queixas. A atividade física foi avaliada pelo questionário International Physical Activity Questionnaire - IPAQ (versão curta). A avaliação da qualidade de vida geral se deu pelo WHOQOL-Bref. A análise estatística foi realizada utilizando o programa estatístico MINITAB version16. Além de análises descritivas das variáveis categorizadas, utilizou-se o teste qui-quadrado de Person com o intuito de verificar possíveis associações entre as variáveis sociodemográficas, comportamentais, clínicas, níveis de atividade física, sintomatologia climatérica, qualidade de vida e a função sexual das mulheres estudadas. Desenvolveu-se a regressão logística para verificar a influência dessas variáveis sobre a disfunção sexual. Considerou-se o nível de significância de 5% para todos os testes. Os resultados mostraram que a média de idade das mulheres estudadas foi de 49,8 (±8,1) anos. Do total dessas mulheres, 67% apresentaram disfunção sexual. Observou-se que 54,5% delas se encontravam na pré-menopausa. Avaliando a influência das variáveis sobre a função sexual; faixa etária (56-65) (p<0,001), estado civil (divorciada/separada) (p < 0,001), escolaridade (baixa) (p=0,017), menopausa (p < 0,001), histerectomia (p = 0,016), nível de atividade física (sedentária) (p=0,002), sintomas do climatério (forte) (p<0,001) e qualidade de vida (baixa) (p<0,001), estiveram associados à disfunção sexual em mulheres de meia idade. Concluiu-se neste estudo que fatores sociodemográficos, clínicos, comportamentais, níveis de atividade física, sintomatologia climatérica e qualidade de vida influenciam significativamente a função sexual na mulher de meia idade

O potencial alelopático de quatro diferentes extratos de plantas medicinais (Eclipta alba, Gomphrena globosa, Tabernaemontana catharinensis e Tithonia diversifolia) foi avaliado na germinação de Bidens pilosa e Lactuca sativa. Dentre os resultados obtidos no teste de germinação, notou-se um maior poder inibitório do extrato de G. globosa sobre sementes e plântulas de Bidens pilosa e Lactuca sativa independente da concentração utilizada e aumento da atividade inibitória de extratos T. catharinensis e de T. diversifolia com aumento da concentração destes. Quanto ao Índice de Velocidade de Germinação, os dados demonstraram redução do índice devido a elevada mortalidade das plântulas submetidas aos extratos de G. globosa e de T. catharinensis e a germinação tardia das sementes submetidas ao extrato de T. diversifolia. Quanto ao vigor das sementes, as menores porcentagens de sobrevivência ocorreram extratos à 2,5% para B. pilosa e 10% para L. sativa.

This work aimed to study the reproduction and description of technique for digital sampling images during rats gait and determination of the sciatic functional index (SFI), through a glass walkway to obtain shoots with a digital camera. After controlled injury by strangulation of sciatic nerve, with 3mm of length, during 30 seconds, using hemostatic forceps, a group of 32 rats was performed 24 hours before the lesion which served as control and 24 hours, 7, 14 and 21 days after injury. The tests consisted in the filming and shooting each animal in order to observe the view from below (by a mirror to 45 degrees) and subsequently analyzed using the IMAGE-J program. Measures were taken from the lengths of the legs (right and left), and the distance between the ankle. In the analysis of IFC, values close to zero (0) suggest that the function of the sciatic nerve is still preserved and values coming from "less one hundred" (-100) indicate total loss of function. It was verified in this study that 24 hours before surgery the average SFI was -7.07 +/- 7.88 and 24 hours after injury these values rose to an average of -77.95 +/- 13.81, being about 10 times larger, where 78% of the animals showed 60 to 100% of functional loss in motor activity, demonstrated by the gradual recovery over the days analyzed, confirming the accuracy and effectiveness of the proposed methodology. These results suggest that studies can be conducted to simplify and reduce costs using the technique for digital images of footprints during rats gait in the laboratory.

Objectives: To analyze different physical activities domains in healthy adults and correlate with cardiovascular risk factors. Methods: The sample was composed by 32 Physical Education undergraduate students, with mean age of 22.6 years old. Adiposity was assessed by waist circumference (WC), body mass index (BMI) and bioelectrical impedance. Additionally, fast glucose (10-12 hours), systolic (SBP) and diastolic (DBP) blood pressure were assessed. Physical activity level was assessed by questionnaire (Baecke et al., 1982). Results: sports activities and leisure time were not related with cardiovascular risk factors. However, job activities were negatively related with %BF, SBP and DBP. Conclusion: Different physical activity domains should be considered when analyzing its associations with health indicators.

It is known that sleep plays an important role in the process of motor learning. Recent studies have shown that the presence of sleep between training a motor task and retention test promotes a learning task so than the presence of only awake between training and testing. These findings also have been reported in stroke patients, however, there are few studies that investigate the results of this relationship on the functionality itself in this population. The objective of this study was to evaluate the relationship between functionality and sleep in patients in the chronic stage of stroke. A cross-sectional observational study was conducted. The sample was composed of 30 stroke individuals in chronic phase, between 6 and 60 months after injury and aged between 55 and 75 years. The volunteers were initially evaluated for clinical data of disease and personal history, severity of stroke, through the National Institute of Health Stroke Scale, and mental status, the Mini-Mental State Examination. Sleep assessment tools were Pittsburgh Sleep Quality Index, the Questionnaire of Horne and Ostberg, Epworth Sleepiness Scale, the Berlin questionnaire and actigraphy, which measures were: real time of sleep, waking after sleep onset, percentage of waking after sleep onset, sleep efficiency, sleep latency, sleep fragmentation index, mean activity score. Other actigraphy measures were intraday variability, stability interdiária, a 5-hour period with minimum level of activity (L5) and 10-hour period with maximum activity (M10), obtained to evaluate the activity-rest rhythm. The Functional Independence Measure (FIM) and the Berg Balance Scale (BBS) were the instruments used to evaluate the functional status of participants. The Spearman correlation coefficient and comparison tests (Student's t and Mann-Whitney) were used to analyze the relationship of sleep assessment tools and rest-activity rhythm to measures of functional assessment. The SPSS 16.0 was used for analysis, adopting a significance level of 5%. The main results observed were a negative correlation between sleepiness and balance and a negative correlation between the level of activity (M10) and sleep fragmentation. No measurement of sleep or rhythm was associated with functional independence measure. These findings suggest that there may be an association between sleepiness and xii balance in patients in the chronic stage of stroke, and that obtaining a higher level of activity may be associated with a better sleep pattern and rhythm more stable and less fragmented. Future studies should evaluate the cause-effect relationship between these parameters

To evaluate the effects of warm-up and stretching, singly or combined, on isokinetic performance and electromyographic activity of the biceps femoris. Materials and methods: Sixty-four volunteers of both sexes, with mean age of 23,1 ± 3,5 years and mean body mass index of 23,5 ± 2,5 Kg/m2 were randomly assigned into 4 groups: control, warm-up (stationary bicycle for 10 minutes), stretching (4 sets of 30 seconds of hamstring muscles static stretching) and warm-up + stretching. All the volunteers were submitted to evaluation pre and post-intervention of the muscle latency time and biceps femoris RMS and the passive torque, peak torque and power of the hamstring muscles. Results: The warm-up + stretching group had reduction of muscle latency time. There was a reduction of RMS during passive torque evaluation in stretching group. The RMS during isometric evaluation was reduced in all experimental groups. The RMS during eccentric evaluation showed reduction in control and warm-up + stretching groups. The passive torque and the eccentric peak torque had no significant differences pre to post-intervention in any group. There was reduction in isometric peak torque in all groups. Conclusion: The warm-up and stretching, when applied in combination can reduce the muscle latency time; stretching protocol promoted neural changes; the protocols used did not alter the muscle viscoelastic properties

Diabetes Mellitus (DM) affected approximately 171 million people in the world in the year 2000 as described by the World Health Organization (WHO). Because DM is a multisystem disease it can cause several complications especially those related to the cardiovascular system. The Peripheral Arterial Disease (PAD) of the lower limbs and the Diabetic Distal Symmetric Polyneuropathy (DDSP) can affect the DM patient causing consequences as the diabetic foot and eventually amputations. The main objective of this study was to determine the prevalence of PAD and sensorial impairment in 73 type 2 DM (DM2) patients and also assess the impact of PAD on quality of life, level of physical activity and body composition. For clinical assessment it was used: the ankle-brachial index (ABI); quantitative sensorial test for tactile sensibility (ST), pain (SD), vibration (SV); Achilles tendon reflex (RA); quality of life questionnaire (SF-36); modified Baecke physical activity questionnaire and bioelectric impedance. Prevalence of PAD in the studied population was 13.7%. ABI was inversely correlated to age (p=0,03; rhô= -0,26), diabetes duration (p=0,02; rhô= -0,28) and blood pressure (p= 0,0007; rhô= -0,33). There were lower scores for physical health summary on the SF-36 in DM2 patients; however, the presence of PAD predominantly mild did not significantly impact quality of life, body composition or physical activity level assessed by questionnaire. Fourteen patients (19.2%) present bilateral and symmetrical alterations in two or more sensorial tests compatible to DPN diagnosis. Abnormalities in ST, SD and SV were present in 27.3%, 24.6% and 8.2%; respectively. There was association of results from ST abnormalities with RA and mainly with SD, suggesting the importance of 10g monofilament use in DM2 routine assessment. In conclusion, the prevalence of PAD in subclinical DM2 was slightly higher compared to the general population and in agreement to previously published data in DM patients. The PAD severity was predominantly mild and still without repercussion on quality of life and body composition. Our study demonstrated a significant prevalence of both PAD and DPN in DM2 without previous diagnosis of these complications and indicates the necessity of early preventive and therapeutic interventions for this population

In most cultures, dreams are believed to predict the future on occasion. Several neurophysiological studies indicate that the function of sleep and dreams is to consolidate and transform memories, in a cyclical process of creation, selection and generalization of conjectures about the reality. The aim of the research presented here was to investigate the possible adaptative role of anticipatory dreams. We sought to determine the relationship between dream and waking in a context in which the adaptive success of the individual was really at risk, in order to mobilize more strongly the oneiric activity. We used the entrance examination of the Federal University of Rio Grande do Norte (UFRN) as a significant waking event in which performance could be independently quantified. Through a partnership with UFRN, we contacted by e-mail 3000 candidates to the 2009 examination. In addition, 150 candidates were approached personally. Candidates who agreed to participate in the study (n = 94) completed questionnaires specific to the examination and were asked to describe their dreams during the examinaton period. The examination performance of each candidate in the entrance examination was provided by the UFRN to the researcher. A total of 45 participants reported dreams related to the examination. Our results show a positive correlation between performance on the examination and anticipatory dreams with the event, both in the comparison of performance on objective and discursive, and in final approval (in the group that not dreamed with the exam the rate of general approval, 22,45%, was similar to that found in the selection process as a whole, 22.19%, while for the group that dreamed with the examination that rate was 35.56%). The occurrence of anticipatory dreams reflectes increased concern during waking (psychobiological mobilization) related to the future event, as indicated by higher scores of fear and apprehension, and major changes in daily life, in patterns of mood and sleep, in the group that reported testrelated dreams. Furthermore, the data suggest a role of dreams in the determination of environmentally relevant behavior of the vigil, simulating possible scenarios of success (dream with approval) and failure (nightmares) to maximize the adaptive success of the individual

O estudo teve o propósito de verificar a influência da textura do recurso pedagógico no tempo despendido e no índice de retidão para execução de uma atividade de encaixe realizada por indivíduos com paralisia cerebral. Participaram do estudo 6 alunos com sequelas de paralisia cerebral do tipo espástica, com idade entre 7 anos e 8 meses e 28 anos e 1 mês. O participante deveria segurar o objeto e levá-lo a um ponto demarcado previamente para o encaixe e, após, retorná-lo à posição inicial. O objeto foi apresentado nas texturas lisa, intermediária e áspera, de forma aleatória. Para a coleta de dados, foi utilizada filmagem para posterior leitura pelo programa Kavideo, que possibilitou cálculos para observar o tempo despendido na tarefa e o índice de retidão. Foi realizado o estudo da normalidade das distribuições, verificada por meio do teste de normalidade de Kolmogorov-Smirnov (Teste KS) e a comparação entre as texturas lisa, intermediária e áspera, no movimento de encaixe, por meio da análise de variância de medidas repetidas. Adotou-se para todos os testes nível de significância de 5% de probabilidade para a rejeição da hipótese de normalidade. O resultado do teste de análise de variância de medidas repetidas mostrou que não houve significância para as variáveis estudadas com o recurso apresentado nas três texturas. Porém, os dados da estatística descritiva mostraram que o encaixe do recurso com a textura lisa despendeu um menor tempo para execução da tarefa e, também, determinou um melhor desempenho com relação à trajetória do movimento.

INTRODUÇÃO: Pacientes com doença renal crônica (DRC) apresentam menor tolerância ao exercício e baixa capacidade funcional, o que os torna, via de regra, sedentários. Outra alteração importante encontrada na DRC é a disfunção cognitiva. O sedentarismo tem sido associado à disfunção cognitiva na população geral, porém, poucos estudos avaliaram essa associação na DRC. OBJETIVOS: Verificar associação entre o nível de atividade física e a função cognitiva de pacientes com DRC que realizam hemodiálise (HD). MÉTODOS: Foram avaliados 102 pacientes que realizam HD. Os participantes responderam o Questionário Internacional de Atividade Física, que avalia o nível de atividade física e o Mini Exame do Estado Mental, utilizado para o rastreamento cognitivo. Os pacientes foram divididos em três grupos conforme a classificação do nível de atividade física (GI: ativos/GII: irregularmente ativos/GIII: sedentários). Foi aplicada análise de regressão logística adotando-se como variável desfecho a presença de disfunção cognitiva e preservando como variáveis independentes aquelas com probabilidade estatística de diferença entre os grupos inferior a 0,1. Foi considerado estatisticamente significante o valor de p inferior a 0,05. RESULTADOS: Os grupos foram semelhantes quanto à idade, tempo de HD, escolaridade e tabagismo. Apresentaram diferença estatisticamente significante quanto à raça, índice de massa corporal, presença de diabetes mellitus, doença de base e grau de déficit cognitivo. Quanto aos dados laboratoriais, os grupos diferiram quanto à creatinina, glicemia, hemoglobina e hematócrito. Houve associação entre o nível de atividade física e função cognitiva, mesmo ajustando-se para as variáveis de confusão. CONCLUSÃO: O maior nível de atividade física associou-se a melhor função cognitiva em renais crônicos em HD, independentemente das variáveis de confusão avaliadas.

The aim of this study was to verify the adherence of participants in a program of physical activity; and to verify if there is any association between the age, Body Mass Index and General Functional Fitness Index with this adherence. It was used the control of frequency for 62 months and data of the anthropometric and functional evaluations of 122 participants (58 + 9 years). 49.2% of the participants gave the program up and 50.8% remained to it. The average of permanence time was 24 + 17 months. The percentage of the adherence of people with satisfactory fitness is greater than with not satisfactory fitness. The percentage of adherence of older people is larger than younger age. The percentage of adherence of not-obese is greater than of obese. However, none of these variables presented statistical difference. It can be concluded that even though there was adherence with similar results even to permanence as to desistance, the time of permanence in the program was very high when compared to other studies.

A monitoração dos níveis de prática de atividade física em segmentos da população jovem tem se tornado importante tema de interesse entre especialistas da área. O Objetivo do estudo foi verificar o nível de atividade física de escolares, baseando-se em duas recomendações vigentes, e analisar a existência de associações entre a quantidade de passos/dia e diferentes indicadores de adiposidade corporal. A casuística foi composta por 162 indivíduos de dez a 18 anos (65 do sexo masculino e 97 do sexo feminino). Foram calculados o Índice de Massa Corporal e o percentual de gordura por impedância bioelétrica. O nível de atividade física habitual foi mensurado por meio de pedômetro (New Lifestyles modelo NL-2000) e analisado de acordo com duas recomendações internacionais: Duncan et al. (masculino: 16.000 passos/dia e feminino: 13.000 passos/dia) e Tudor-Locke et al. (masculino: 15.000 passos/dia e feminino: 12.000 passos/dia). O teste t de Student e a ANOVA One-Away (Post Hoc - LSD) compararam os grupos formados. O nível de significância adotado foi de 5% (p£0,05). Dos resultados, apenas 18,5% da amostra cumpriu as recomendações propostas por Duncan e 25,9% cumpriram os pontos de corte propostos por Tudor-Locke et al.. Os adolescentes que não cumpriram as recomendações propostas por Duncan et al., apresentaram valores percentuais de gordura corporal maiores quando comparados aos jovens que cumpriram (p<0,05). Pode-se concluir que uma elevada taxa de jovens não cumpriu as duas recomendações analisadas, bem como, apenas um indicador de adiposidade associou-se com o cumprimento de umas das recomendações.
