Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by chronic airflow limitation that leads beyond the pulmonary changes to important systemic effects. COPD is characterized by pulmonary and systemic inflammation. However, increases in the levels of inflammatory cytokines in plasma are found even when the disease is stable.(More)
OBJECTIVE The purpose was to assess functional (balance L-L and A-P displacement, sit-to-stand test (SST) and Tinetti scale - balance and gait) and neurophysiological aspects (patellar and Achilles reflex and strength) relating these responses to the BODE Index. INTRODUCTION The neurophysiological alterations found in patients with chronic obstructive(More)
OBJECTIVES The Sit-to-Stand test (SST) is accepted and utilized during functional assessments of COPD patients, along with the 6-Minute Walk test (6MWT). Since there is a lack of evidence in literature regarding the neurophysiological effectiveness of SST compared to 6MWT, the present study is justified with the purpose of assessing the neurophysiological(More)
INTRODUCTION Pulmonary rehabilitation (PR) is a multidisciplinary program of care for patients with chronic obstructive pulmonary disease (COPD) with the goal of improving the functional capacity and quality of life, as well as maintaining the clinical stability of COPD sufferers. However, not all patients are available for such a program despite discomfort(More)
OBJECTIVE To analyze serum C3 and C4 complement system components with a view to their possible utility as biomarkers of intermittent atopic asthma. METHODS Serum levels of the C3 and C4 complement components were assayed in 70 children aged from 3 to 14 years and with a history of "wheezy chest." After 2 years' outpatients follow-up and after application(More)
[Purpose] This study evaluated the effect of Bilevel Positive Airway (BiPAP) on the autonomic control of heart rate, assessed by heart rate variability (HRV), in patients hospitalized with decompensated heart failure. [Subjects and Methods] This prospective cross-sectional study included 20 subjects (age: 69±8 years, 12 male, left ventricular ejection(More)
UNLABELLED This 12-week study compared the efficacy and safety of a fixed combination of fluticasone propionate plus formoterol (FL/F) 250/12 μg b.i.d. administered via a dry powder inhaler (DPI) (Libbs Farmacêutica, Brazil) to a combination of budesonide plus formoterol (BD/F) 400/12 μg b.i.d. After a 2-week run-in period (in which all patients were(More)
The purpose of this study was to investigate the physiological variables of lung function, respiratory muscle strength, and sleep in clinically stable patients with myasthenia gravis. This was a prospective cross-sectional study conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Patients(More)
BACKGROUND The adequate control of asthma includes the absence of nocturnal symptoms, minimal use of medication, normal or nearly normal lung function and no limitations to physical activity. The choice of a more sedentary lifestyle can lead to physical de-conditioning, thereby aggravating asthma symptoms and increasing the risk of obesity. METHODS This(More)
