Qualidade subjetiva do sono e queixa de insônia em pacientes com Acidente Vascular Cerebral

Brain injury can be associated with changes in the sleep-wake cycle. However, studies about sleep disturbances and their relationship with quality of sleep are scarce. Besides, it remains to be known how stroke affects the mechanisms of sleep. The aim of this study was to investigate quality of sleep, complaints of sleep disturbances and associated factors in stroke patients from the Physical Therapy services in Natal -RN. This was a cross-sectional descriptive study involving 70 individuals (aged 45-65 years), 40 patients (57 ± 7 years), 11 ± 9 months after injury, and 30 healthy individua ls (52 ± 6 years), evaluated with the Pittsburgh Sleep Quality Index (PSQI) and Sleep Habits Questionnaire. The data were analyzed by Chi-square test, t Student test and logistic regression. Poor quality sleep was found in 57,5% of the patients (6,3 ± 3,5) and was significantly higher than in the control population (3,9 ± 2,2) (t Student test, p=0,002). The patients showed significantly higher value of PSQI than controls: sleep latency (p=0,019), length of sleep (p=0,039) and dysfunction during the day (p=0,001). Regarding complaints of sleep disturbances (dyssomnias and parasomnias) analyzed by Chi-square test, the complaint of insomnia was the most prevalent (patients: 37,5%; healthy subjects: 6,7%; p=0,007). Regression analysis showed that sl eep latency (p=0,036) and complaint of insomnia (p=0,036) were associated with quality sleep. In addition, female gender (p=0,036) and complaint of broken sleep (p=0,003) were considered risk factors for the presence of insomnia. Our results show that stroke affects the homeostatic process of sleep. Shorter sleep latency and the absence of insomnia are considered protective factors for good sleep quality and this should be taken into consideration in the diagnostic and therapeutic strategies

Reconhecimento de seqüências de atividades funcionais em pacientes com acidente cascular encefálico

During the motor rehabilitation of patients with neurological pathologies, there are many factors that have an influence on the therapeutical process. It is possible that the demonstration using videotapes or photographs of movements that will be learned can assist the codification, classification and reorganization of the elements of the task in familiar diagrams and thus facilitate the process of motor rehabilitation. The aim of this study was to analyze the performance in the test of recognition of sequences of functional activities such as water drinking and hair combing presented partially (by photos) and completely (by video) to the patients with encephalic vascular accident . The sample was generated from 12 patients (62 ± 8 years) and 10 healthy subjects (53 ± 5 years), of both sex, divided in two groups for which 5 functional activities were presented partially and completely, in 4 sequences that varied between reached and not reached objectives and correct and incorrect movements, during 24 trials. The test t'Student was applied to verify differences in the recognition time between the groups, and to compare the performance between the tests carried through at 9:00 am and retests at 9:00 am and 4:00 pm. To compare the frequency between the types of reply, the test Qui-square was used. It was verified that the patients presented a greater recognition time and a lower number of correct answers than the healthy subjects, and had better performances in the recognition of the complete sequence than the partial one. Bigger frequency was observed in the reply that the objective and the movement were being presented correctly, however the healthy subjects had soon indicated the correct reply in the first trials. An improvement tendency was observed in the performance, when the stages of tests and retests had been carried through in the same schedule. According to the results, it is suggested that the patients with stroke can better recognize the correct movements of a functional activity when it is presented completely in video form, what can influence the choice of the therapeutical strategy during the process of motor rehabilitation

Efeito da oferta dietética de proteína sobre o ganho muscular, balanço nitrogenado e cinética da 15N-glicina de atletas em treinamento de musculação

The effect of increased protein intake on the muscle mass gain, nitrogen balance and N-15-glycine kinetics was studied in six young, healthy subjects practitioners of strength training (> 2 years), without use of anabolic steroids and in agreement with the ethical principles of the research. All athletes received adequate diet (0.88g protein/kg/day) during 2 weeks prior the study (D1), and thereafter with diet providing 1.5g of protein/kg/day and 30kcal/g of protein (D2 diet) for the subsequent 2 weeks. Later on, they all received diet with 2.5g of protein/kg/day (D3 diet) and 30 kcal/g protein for the last two weeks. Body composition, food intake, blood biochemistry, nitrogen balance (NB) and 15N-glycine kinetics were determined at the beginning, after D1 (M0) and in the last days of the D2 (M1) and D3 (M2). The results showed at the end of the study (4 weeks) significant increase in muscle mass (1.63 +/- 0.9kg), without difference between D2 and D3. The NB followed the protein/energy consumption (M0 = -7.8g/day; M1 = 5.6g/day and D3 = 16.6g/day), the protein synthesis followed the NB, with M0 < (M1= M2) (M1 = 49.8 +/- 12.2g N/day and M2 = 52.5 +/- 14.0g N/day). Protein catabolism rate was similarly kept among diets. Thus, the results of the NB and N-15-glycine kinetics indicate that the recommended protein intake for these athletes is higher than the one for sedentary adults (0.88g/kg) and lower than 2.5g/kg, around 1.5g of protein/kg/day, with adjustment of the energy consumption to 30 kcal/g of protein.

O tabagismo como fator de risco para as doenças periodontais: aspectos microbiológicos

O fumo é considerado importante fator predisponente para muitas doenças, incluindo-se as periodontopatias. Desde que as doenças periodontais representam a inter-relação entre os fatores de virulência da microbiota subgengival sobre um hospedeiro susceptível, foi objetivo avaliar a freqüência de isolamento de três periodontopatógenos em indivíduos sadios e pacientes com doença periodontal, fumantes ou não, com níveis variados de higiene bucal; verificar a relação entre o número de microrganismos produtores de sulfeto de hidrogênio na placa subgengival de fumantes e não fumantes e sua condição clínica. Foram examinados 189 pacientes e indivíduos sadios, dos quais 60 foram selecionados para análise microbiológica. O índice de placa foi registrado de acordo com o índice de O'Leary e os espécimes de placa subgengival coletados e processados de acordo com SLOTS35 (1982). A identificação dos isolados foi obtida pelas suas características morfocelulares, morfocoloniais e bioquímico-fisiológicas. Verificou-se que a freqüência de isolamento dos bastonetes anaeróbios produtores de pigmento negro, Fusobacterium nucleatum e bactérias produtoras de sulfeto de hidrogênio foi similar entre fumantes e não fumantes, sendo mais elevada nos pacientes com doença periodontal. Já Actinobacillus actinomycetemcomitans foi isolado mais freqüentemente em sadios fumantes do que sadios não fumantes.

Efeito da espasticidade sobre os padrões lineares de marcha em hemiparéticos

INTRODUÇÃO: A hemiparesia após o acidente vascular encefálico (AVE) é a sequela mais frequente, prejudicando a velocidade de execução dos movimentos automáticos, diminuindo a autonomia do indivíduo e gerando incapacidade. OBJETIVOS: Analisar o efeito da espasticidade nos padrões lineares de marcha (PLM) em indivíduos hemiparéticos. MÉTODOS: Foram estudados dois grupos: 20 indivíduos com AVE (G1) e 20 indivíduos sadios, destros, sem sequela neurológica (G2), com média de idade de 54,2 e 52,6 anos respectivamente. Foram avaliados os PLM pelo protocolo de Nagazaki, o tônus muscular pela escala de Ashworth modificada e o arco de movimento por goniometria. Foi feita comparação dos parâmetros nos dois grupos pelo teste t de Student e correlação de Spearman com nível de significância de 5%. RESULTADOS: A média da distância foi de 14,52 m e 32,16 m, e o tempo foi de 23,75 s e 19,02 s no G1 e G2 respectivamente (p < 0,0001). Na comparação entre os grupos, a amplitude média de passo e a velocidade média foram estatisticamente significantes (p < 0,05) e a cadência não mostrou significância (p = 0,1936). Quando os PLM foram comparados com o grau de espasticidade dos músculos gastrocnêmio e sóleo, mostraram associação negativa com distância, amplitude de passo e velocidade e associação positiva com o tempo (p < 0,05). CONCLUSÃO: Quanto maior o grau de espasticidade dos músculos gastrocnêmio e sóleo, menores serão os parâmetros lineares de marcha do indivíduo com sequela de hemiparesia pós-AVE.
