RESUMO

BACKGROUND AND OBJECTIVE: Physical activity is an important parameter in patients with chronic obstructive pulmonary disease, but has not been studied in detail in patients with interstitial lung disease. This study aimed to evaluate physical activity in patients with idiopathic pulmonary fibrosis (IPF). METHODS: Physical activity was monitored in 31 stable IPF patients using an accelerometer for 1 month. The following factors reflecting physical activity were measured: the number of steps, walking distance, the time spent at magnitude of movement (MM) 1-6, physical activity-related energy expenditure (PAEE) and total energy expenditure. We also measured the following clinical parameters: the modified Medical Research Council (MRC) scale, Krebs von den Lungen-6 (KL-6), pulmonary function parameters, 6-min walk test (6MWT) results and high-resolution computed tomography (HRCT) findings of the chest. We determined the relationship between these parameters and physical activity. RESULTS: We recorded 24 days of physical activity data. The time spent at MM < 1 was more than 10 h per day, whereas that at MM > 1 was approximately 1 h per day. The modified MRC scale, serum KL-6 levels, 6MWT distance, and the extent of honeycomb and reticular abnormality on HRCT were associated with several facets of physical activity. In particular, lower KL-6 levels were correlated with higher physical activity based on the number of steps, walking distance, the time spent at MM 1-4 and PAEE. CONCLUSIONS: The modified MRC scale, 6MWT distance, extent of fibrosis on HRCT and serum KL-6 levels are strongly associated with physical activity.

RESUMO

Objectives: This retrospective observational study investigated whether the degree of muscular echogenicity in patients admitted to the intensive care unit (ICU) could help with the early detection of ICU-acquired weakness (ICU-AW) and predict physical function at hospital discharge. Methods: Twenty-five patients who were mechanically ventilated for more than 48 h in the ICU were enrolled. We also enrolled 23 outpatients with nonmuscular diseases as the control group. The target sites for measuring muscular echogenicity were the upper arm and lower leg. First, the muscular echogenicity was compared between surviving nonsurgical patients admitted to the ICU and stable outpatients with nonmuscular diseases. Second, we investigated the relationship between muscular echogenicity and clinical features, e.g., the manual muscle test (MMT), Medical Research Council (MRC) sum score, and Functional Independence Measure (FIM). Results: Muscular echogenicity in the upper arm in the ICU group was significantly higher than that in the control group. In the ICU group, the degree of muscular echogenicity of the upper arm was inversely correlated with the MMT of elbow flexion (P=0.006; r=-0.532) and the MRC sum score (P=0.002; r=-0.591). However, muscular echogenicity of the upper arm did not correlate with functional FIM (P=0.100; r=-0.344) at hospital discharge. Conclusions: Critically ill patients can experience pathological muscle weakness associated with increased muscular echogenicity in the upper arm. Additionally, the degree of muscular echogenicity in the upper arm correlated with the MRC sum score and can facilitate early detection of ICU-AW. The relationship between echogenicity and functional outcome at discharge requires elucidation.
