The stroke, cause of morbidity and mortality, has been associated with imbalance in the neural control of the heart, which contributes to the decrease in heart rate variability (HRV) and a prognostic factor for cardiacevents and arrhythmias. The aim of this study was to in investigate the autonomic modulation of heart rate of men suffering from lesions stroke in chronicphase. Eight menaged 58.62 ± 2.88 years, 27.41 ± 5.33 kg/m2of bodymass índex, with paresis for at least six months were studied. Heart rate (HR) and RR intervals (iR-R) were recorded at rest in supine position for 10 minutes. Geometric índices of the Poincaré plot were calculated: SD1, associatedwith vagal activity; SD2, associated with global activity but sympathetic predominance, and the relationship of both (SD1/SD2). Geometric index values in the sample: SD1 = 20,54 ± 9,90ms; SD2 = 36,80 ± 30,61ms; SD1/SD2 = 0,49 ± 0,04. The reference values from literature for healthy subjects are: SD1 = 19.6 ± 9.4ms e 22.8 ± 16.1 ms; SD2 = 43.2 ± 17.7 ms e 56.3 ± 12.3 ms; SD1/SD2 = 0.49 ± 0.21ms. Men in chronic phase of stroke haven't autonomic dysfunction analyzed by nonlinear method – Poincaré geometricíndices.

Patients with Chronic Obstructive Pulmonary Disease may have muscle dysfunction, which ultimately reduce the functional capacity. Neuromuscular electrical stimulation (NMES) is a technique that can be effective in these patients, and implies low overload to the cardiorespiratory system. The aim of this study was to investigate the effects of NMES on muscle strength and cardiorespiratory fitness in COPD patients. Five patients (2 men, 3 women) were evaluated, with a mean age of 70.40 ± 6.61 years, and underwent anamnesis, anthropometric measurements, spirometry, pulmonary function, cardiopulmonary functional capacity and muscle strength in the lower limbs. After the evaluations, the patients were enrolled in a program of electrical stimulation of the quadriceps muscles, performed 3 times per week for 5 weeks. Each session lasted for 30 minutes, being reassessed at the end of the 15 sessions. Statistically significant response is observed to gain strength in lower limb (p = 0.005), but no significant responses were observed for the distance in six minute walking test before and after the test protocol for electrical stimulation. Showing that with NMES was located just gain muscle strength without effects on functional capacity, and there are few studies that investigate these effects, so further studies are needed to investigate this relationship.

Introduction: The pulmonary rehabilitation (PR) is composed of aerobic and resisted exercises that improve the functional capacity to the exercise, life quality and decrease respiratory symptoms in subjects with chronic pulmonary disease. Objective: Assess the effects of a combined PR program in the cardiorespiratory function and peripheral muscle strength in subjects with chronic pulmonary disease. Method: Patients with chronic pulmonary disease were submitted to the PR program, which was developed on 24 sessions of 60 minutes (three times per week). The program was composed of aerobic exercises (two times per week) and resisted exercises (once a week). Before and after the PR the patients were submitted to manovacuometry in order to measure the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP), ventilometry, peek expiratory flow (PEF), six minute walking test (6MWT) and one maximum repetition (1RM). The data are presented in absolute frequency, percentage and mean±standard deviation. The t Student test was used to compare data before and after the PR and the ANOVA test to compare before, after and predicted distances in the 6MWT (p<0.05). Results: Seven patients were part of this study, 85.70% of women, 71.40% with pulmonary emphysema diagnosis. The mean age was 69.43±5.59 years old, the height was 1.61±0.07 m, the mean weight was 66.20±8.40 kg and the body mass index mean was 25.50±2.48 kg/m². From the variables assessed, the MEP increased from 79.71±13.69 to 84.42±12.83 cmH2O (p=0,03), the PEF increase from 255.71±66.3 to 320.00±93.63 l/min (p=0,03) and the distance in the 6MWT from 415.28±47.90 to 483,79±79,77 m (p=0,02). The load in the 1RM test in the reverse peck deck exercise (before - - 17.10±8.10kg; after – 210.40±9.00kg), knee in leg extension machine (before – 17.10±9.50kg; after – 26.40±13.10kg) and hip extensors (right before – 48.60±22.10kg; after – 62.90±19.30kg; and left before – 46.40±20.10kg; after – 62.10±18.20kg) increased significantly (p<0,05). Conclusion: After the PR program there was improvement in the expiratory muscular strength, in the lower limbs strength and in the functional capacity. Besides that, there was a reduction in the airflow obstruction of the subjects with chronic pulmonary disease.

A Doença Inflamatória Intestinal (DII) engloba, fundamentalmente, duas doenças distintas: a Doença de Crohn (DC) e a Colite Ulcerativa (CU), ambas caracterizadas por uma inflamação crônica do intestino, com períodos de exacerbação seguidos de intervalos prolongados de remissão dos sintomas. Apesar da DII ser objeto de pesquisa há várias décadas, a sua etiologia ainda é desconhecida e seu tratamento envolve uma série de fármacos com sérios efeitos colaterais, especialmente quando usado cronicamente. As cumarinas representam uma importante classe de compostos fenólicos naturais que apresentam inúmeras propriedades farmacológicas importantes para que um produto seja potencialmente ativo no tratamento da DII. Dentre as inúmeras cumarinas conhecidas e estudadas, dados obtidos em nosso laboratório demonstram que algumas cumarinas apresentam efeitos protetores na fase aguda e preventiva do processo inflamatório intestinal induzido por TNBS (ácido trinitrobenzenosulfônico) em ratos, reduzindo a incidência de diarréia, aderência e obstrução intestinal, além de manterem os níveis de glutationa e reduzirem a atividade da fosfatase alcalina e da mieloperoxidase colônica. Os objetivos do presente projeto são determinar a atividade antiinflamatória intestinal da escopoletina e fraxetina na fase aguda e crônica com recidiva de colite ulcerativa induzida por TNBS tendo-se em vista a determinação de sua atividade curativa. Para tanto, serão avaliados os parâmetros clínicos gerais (consumo de alimento e peso corporal), parâmetros macroscópicos da lesão (determinação de índice de lesão, relação peso-comprimento colônico) e bioquímicos (avaliação das atividades da mieloperoxidase, fosfatase alcalina, níveis de proteínas e glutationa total)

It is understood by Chronic Renal Failure (CRF) or Stage IV Chronic Kidney Disease (CKD) the morbid state in which there is a substantial and irreversible loss of functional capacity, metabolic and endocrine function in both kidneys, leading to a framework of dehydration, azotemia, electrolyte imbalance, anemia, uremic syndrome, secondary hyperparathyroidism, among other conditions that make the patient's life without treatment unfeasible. An adequate nutritional support to patients with CKD at any stage aims to maintain a good clinical condition and an attempt to delay the progression of the disease. The basis of a diet for patients with CKD is the restriction in this protein being of high biological value, low-phosphorus, high energy density, fiber and antioxidants combined with a good dietary practices that allow the patient a good quality of life

Uremic syndrome, arising from kidney malfunction, consists of a set of systemic changes caused by the accumulation of toxic substances to the body. Since, with the advance of medicine, the animals lived more reaching advanced age and entering thus on track of senility, chronic renal disease, became a common complaint in the routine of the ambulatory. This high rate of morbidity generates an increased need for clarification of pathophysiology involved in this disease. The components of the uremic syndrome include water and sodium imbalance, anemia, intolerance to carbohydrate, neurological disorders, disorders of the gastrointestinal tract, osteoarthritis, immunological incompetence and metabolic acidosis. The clinical manifestations occur in isolation or in combination. In most cases canines patients are subject to an assessment when the kidney disease has evolved to the final stage with uremic syndrome and installed already, under these conditions, the prognosis is reserved

A Doença Renal Crônica (DRC) é considerada um problema mundial de saúde pública. O paciente com DRC apresenta baixa tolerância ao exercício físico e como conseqüência apresenta limitações na capacidade funcional e força muscular respiratória. O paciente com DRC em programa de hemodiálise pode sofrer impactos negativos na sua capacidade funcional. Objetivo: Avaliar a capacidade funcional e a força muscular respiratória associada ao exercício físico em pacientes com doença renal crônica que realizam hemodiálise. Metodologia: 28 pacientes de ambos os sexos com idade entre 40 e 60 anos participaram do estudo, em programa de hemodiálise no Instituto do Rim da Santa Casa de Misericórdia de Presidente Prudente-SP. Os pacientes foram avaliados pela força muscular inspiratória (PImax) e força muscular expiratória (PEmax) pela manovacuometria e Teste de Caminhada de Seis Minutos (TC6’) para avaliar a capacidade funcional. Após as avaliações, os pacientes iniciaram o programa de atividade física, com duração de oito semanas, realizado 3 vezes por semana durante 40 minutos na hemodiálise. Ao final do programa de exercícios físicos, os pacientes foram reavaliados. Resultados: Na avaliação da força muscular respiratória o valor da PImax pós foi significativamente maior que o valor obtido na avaliação pré programa (p<0,05), para a variável PEmax não foi encontrada diferença significativa entre os momentos pré e pós intervenção (p<0,05). As avaliações da capacidade funcional ou Teste de Caminhada de Seis Minutos (TC6’) inicial e após o programa de exercícios, não apresentaram diferenças significativas (p<0,05). Dados da Escala de Borg indicaram redução significativa do cansaço e dispnéia (p<0,05), após o programa de exercícios. Os indicadores relativos à dor foram reduzidos, após o programa, em relação ao pré (p<0,05). Conclusão:... (Resumo completo, clicar acesso eletrônico abaixo)
