BACKGROUND Most guidelines recommend either a long-acting beta-agonist (LABA) plus an inhaled glucocorticoid or a long-acting muscarinic antagonist (LAMA) as the first-choice treatment for patients with chronic obstructive pulmonary disease (COPD) who have a high risk of exacerbations. The role of treatment with a LABA-LAMA regimen in these patients is(More)
Classification of chronic obstructive pulmonary disease (COPD) is usually based on the severity of airflow limitation, which may not reflect phenotypic heterogeneity. Here, we sought to identify COPD phenotypes using multiple clinical variables. COPD subjects recruited in a French multicentre cohort were characterised using a standardised process. Principal(More)
The aims of this survey were to determine the prevalence of symptoms indicative of chronic bronchitis (CB) in the French adult population, to identify the role of risk factors for CB, and to assess rates of CB diagnosis and pulmonary function testing (PFT) in the presence of CB. A representative sample of 14,076 individuals aged > or = 25 yrs completed a(More)
Motor skill acquisition in the lower limb may induce modifications of spinal network excitability. We hypothesized that short-term motor adaptation in precision grip tasks would also induce modifications of cervical spinal network excitability. In a first series of experiments, we studied the impact of two different precision grip force control tasks (a(More)
This retrospective study assessed the prognostic factors associated with early and long-term outcome in consecutive patients with acute myeloid leukaemia (AML) admitted to the intensive care unit (ICU) over a 9-year period. A total of 83 patients were studied (age 48 +/- 16 years), among whom 60% were neutropenic on admission. For 68%, admission occurred(More)
Because forced expiratory volume in 1 s is a poor descriptor of chronic obstructive pulmonary disease (COPD) heterogeneity [1], interest has emerged regarding the identification of clinically relevant COPD phenotypes [2, 3]. We recently reported the usefulness of applying mathematical models (i.e. principal component and cluster analyses) to multiple(More)
BACKGROUND Protease-activated receptors (PARs), which are G protein-coupled receptors that are activated after proteolytic cleavage of the amino terminus of the receptor, are likely to play a major role in airway inflammation. PARs are activated by endogenous proteases, including thrombin (PAR-1, -3, and -4) and tryptase (PAR-2 and -4), both of which are(More)
BACKGROUND Epidemiologic studies indicate that chronic cough and sputum production are associated with increased mortality and disease progression in COPD subjects. Our objective was to identify features associated with chronic cough and sputum production in COPD subjects. METHODS Cross-sectional analysis of data were obtained in a multicenter (17(More)
The main goal of clinical practice guidelines is to help clinical decision by practitioners, who can not integrate in their daily practice all the published data concerning new technologies and knowledge. Guidelines also have growing applications in the ethical, legal, socio-economic, public policy and health care funding fields. This article describes the(More)
