Background And Objectives: Chronic Obstructive Pulmonary Disease as defined by the Global initiative for chronic obstructive lung disease is a common preventable and treatable disease, is characterized by persistant airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lungs to noxious particles or gases. Exacerbation...

BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that reduces functional capacity, deteriorating the ability to perform activities of daily living (ADL). A close relationship between morbidity and mortality with functional limitation is observed in patients with COPD. OBJECTIVES To determine if there is a relationship between ADL limitation and the BODE index, ...

STUDY OBJECTIVES To verify whether and to what extent the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index correlates with a disease-specific index of health status in patients with COPD. DESIGN Cross-sectional study. SETTING University-affiliated hospital. PATIENTS One hundred patients with stable COPD recruited from the outpatient clinic of a single inst...

Bode plots, corrected for Ohmic resistance, logarithmic plots of the imaginary component of the impedance, and effective capacitance plots are shown to be useful complements to the more traditionally used complex-plane and Bode representations for electrochemical impedance data. The graphical methods are illustrated by synthetic data and by experimental data associated with corrosion in saline ...

Descriptions of time use patterns in people with chronic obstructive pulmonary disease (COPD) are scarce and the relationship between use-of-time and COPD severity remains unclear. This study aimed to describe a typical day for people with COPD and to explore the differences in time-use patterns across the Body Mass-Index, Airflow Obstruction, Dyspnoea and Exercise Capacity (BODE) index using c...

We aimed to measure physical activity in patients with COPD, to identify the disease stage at which physical activity becomes limited, to investigate the relationship of clinical characteristics with physical activity, to evaluate the predictive power of clinical characteristics identifying very inactive patients, and to analyze the reliability of physical activity measurements. 163 patients wi...

The Global initiative for Chronic Obstructive Lung Disease (GOLD) staging has widely used in the stratification of the severity of COPD, while BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index was proven superior to FEV1 in predicting mortality, exacerbation and disease severity in patients with COPD. Clinical COPD Questionnaire (CCQ), a questionnaire with ten it...

BACKGROUND Recently, it has been shown that emphysematous destruction of the lung is associated with a decrease in the total number of terminal bronchioles. It is unknown whether a similar decrease is visible in the more proximal airways. We aimed to assess the relationships between proximal airway count, CT imaging measures of emphysema, and clinical prognostic factors in smokers, and to deter...

BACKGROUND The value of quantitative CT (QCT) to identify chronic obstructive pulmonary disease (COPD) phenotypes is increasingly appreciated. The authors hypothesised that QCT-defined emphysema and airway abnormalities relate to St George's Respiratory Questionnaire (SGRQ) and Body-Mass Index, Airflow Obstruction, Dyspnea and Exercise Capacity Index (BODE). METHODS 1200 COPDGene subjects mee...
