Efeitos da Reeducação Postural Global na Hipercifose e nas Variáveis Respiratórias de Idosos Relato de Dois Casos

Examine the effects Global Postural Reeducation, (GPR) in hyperkyphosis and respiratory variables in the elderly was the objective in the research. For this, two elderly participated, one is 62 years old (voluntary 1) and another is 66 years old (voluntary 2), without lung, heart, kidney and/or skeletal-muscle diseases diagnosed. The volunteer have been assessed for Quality of Life (QOL) through the questionnaire SF-36, the degree of toracic kyphosis, the muscular respiratory strength and the thoracic-abdominal mobility. The GRP treatment consisted in eight sessions applied, once one hour each session. After the eight sessions the volunteer were reevaluated. The data concerning assessments before and after treatment were analysed describly. According to the results there was an improvement in the degree of kyphosis in both volunteers, highlighting voluntary 2. Respiratory variables also improvements after treatment. In relation to the Quality of life in most areas there has been an increase in scores indicating improved QOL. These data showed that the GPR has been effective to decrease the level of kyphosis, improves respiratory variables and the quality of life in the elderly treated. However, further work with a greater number of subjects must be carried out to analyze the effectiveness of therapy in the elderly.

Cardiovascular responses induced by acute video game boxing performance in healthy women

BACKGROUND: Previous studies suggested that some interactive video games induce cardiovascular responses. However, some different styles of video games have not been investigated. OBJECTIVE: We aimed to evaluate cardiovascular responses induced by video game boxing performance in healthy women. METHOD: We evaluated ten female sedentary volunteers, aged 20.9 ± 1.4 years, weight 58.7 ± 8.0 kg, height 163.2 ± 5.4cm. All subjects were weighed and measured. Their heart rate, blood pressure and lactate levels were recorded before and after video game performance. The volunteers played a Sony video game (Nintendo® Wii) by using the boxing method, in which all volunteers played for 10 minutes without interruption. At the end of the game the volunteers were reassessed using the same parameters mentioned above. RESULTS: At the end of the video game boxing performance we observed highly significant increases of lactate production (p < 0.0035) and the double product (heart rate vs. systolic blood pressure) was also higher (p < 0.0001). Both parameters indicate that the performance increased demands of the cardiovascular system. CONCLUSION: We conclude that a ten-minute video game boxing performance induces cardiovascular responses similar to aerobic exercise. This may be a practical form of exercise, but care should be exercised concerning subjects with cardiovascular disorders.

Cardiac autonomic responses induced by auditory stimulation with music is influenced by affinity

INTRODUCTION: We aimed to evaluate the effects of musical auditory stimulation on cardiac autonomic regulation in subjects who enjoy and who do not enjoy the music. METHOD: The study was performed in young women (18-27 years old) divided in two groups (1) volunteers who enjoyed the music and (2) volunteers who did not enjoy the music. Linear indices of heart rate variability were analyzed in the time domain. The subjects were exposed to a musical piece (Pachelbel: Canon in D Major) during 10 minutes. Heart rate variability was analyzed at rest with no music and during musical auditory stimulation. RESULTS: In the group that enjoyed the music the standard deviation of normal-to-normal R-R intervals (SDNN) was significantly reduced during exposure to musical auditory stimulation. We found no significant changes for the other linear indices. The group composed of women who did not enjoy the music did not present significant cardiac autonomic responses during exposure to musical auditory stimulation. CONCLUSION: Women who enjoyed the music presented a significant cardiac autonomic response consisting of a reduction in heart rate variability induced by the musical auditory stimulation. Those who did not enjoy the musical piece presented no such response.

Atualidades sobre a doença de Chagas, com ênfase nas possíveis causas da cardiomiopatia crônica

A Organização Mundial de Saúde estima que existem cerca de 10 milhões de infectados pelo Trypanosoma cruzi, 30% dos infectados cronicamente desenvolvem alterações cardíacas, e 10% digestivas e neurológicas. O T. cruzi é um protozoário cinetoplástida flagelado agente etiológico da tripanossomíase americana, popularmente conhecida como a Doença de Chagas, uma antropozoonose conhecida na América Latina. Pelo menos 40 espécies de triatomíneos – conhecido por barbeiros – carregam o protozoário. O gênero Triatoma representa o principal vetor da Doença de Chagas e são adaptados a climas secos de ambientes rurais da América do Sul e Central. Outras formas de infecção podem ocorrer por transfusão de sangue, transplantes, via oral, e transmissão vertical. Há duas fases que caracterizam a infecção pelo T. cruzi: a fase aguda, apresentando um período de incubação de uma semana a um mês, que geralmente é assintomática. Já a fase crônica é mais polêmica e divide a opinião dos pesquisadores, mas basicamente mostra-se como uma cardiomiopatia chagásica, ou uma dilatação no trato digestivo e ainda pode causar lesões no sistema nervoso parassimpático e simpático. Entre essas duas fases ocorre um período indeterminado em que não há nenhuma manifestação clínica da doença. Existem teorias que explicam a patogenicidade das lesões da doença: uma postula que as lesões características da Chagas são referentes à ruptura das células parasitadas e subsequente inflamação. Outra é a teoria da autoimunidade, em que o próprio sistema imune do indivíduo rejeita as células livres de parasitas causando as lesões características da doença. Há evidências substanciais que comprovem a participação das respostas imunes nas lesões miocárdicas, mas como o parasito consegue desencadear estas respostas imunes, ainda não está esclarecido...

Antidepressivo em ratos com insuficiência aórtica pode modificar a expressão gênica de ocitocina e vasopressina centrais?

Aortic regurgitation (AR) leads to a left ventricle dilation and hypertrophy in response to a chronic volume overload. It is still very frequent in developing countries, for instance Brazil, and often as secondary to rheumatic fever. Usually, chronic AR is generally well tolerated for many years, when with the heart dilated the patient searches for treatment. Bidirectional association with depression and cardiovascular disease has been described. Selective serotonin reuptake inhibitors (SSRI) are widely prescribed to treat several affective disorders, especially for cardiovascular patients since they decrease arrhythmia probability. These SSRI improves cardiac function in rats submitted to stress protocols. Preliminary study from our laboratory showed that following 4 weeks of treatment with one SSRI (paroxetine) in subchronic AR rats there was a decreased in daily sodium intake and an improvement in systolic function. An increase in the central oxytocinergic transmission may be involved in this peripheral improvement to the heart. The investigations about the mechanisms underlying this improvement are necessary. Therefore the aims of this project is investigate the effects of 4 weeks of treatment of paroxetine, a SSRI, in rats with a subchronic AR over the central central gene expression of oxytocin and vasopressin using a reverse transcription polymerase chain reaction (RT-PCR)
