Multicenter Study Comparative StudyRestrictive spirometry pattern is associated with low physical activity levels. A population based international study.
Restrictive spirometry pattern is an under-recognised disorder with a poor morbidity and mortality prognosis. We compared physical activity levels between adults with a restrictive spirometry pattern and with normal spirometry. ⋯ Adults with a restrictive spirometry pattern were more likely to report low levels of physical activity than those with normal spirometry. These results highlight the need to identify and act on this understudied but prevalent condition.

Possible role of airway microvascular permeability on airway obstruction in patients with chronic obstructive pulmonary disease.
Airway microvascular system participates in the airway inflammation that is central to the pathophysiology of inflammatory lung disorders. ⋯ Airway microvascular permeability in the peripheral airways is increased in patients with COPD, and is associated with the severity of airway obstruction. We may need to consider this characteristic feature as a target in any therapeutic strategy for the treatment of the disease. (237 words).

ReviewPleural manometry in patients with pleural diseases - the usefulness in clinical practice.
Although pleural manometry is a relatively simple medical procedure it is only occasionally used to follow pleural pressure (Ppl) changes during a therapeutic thoracentesis and pneumothorax drainage. As some studies showed that pleural pressure monitoring might be associated with significant advantages, pleural manometry has been increasingly evaluated in the last decade. The major clinical applications of pleural pressure measurements include: the prevention of complications associated with large volume thoracentesis, diagnosis and differentiation between various types of an unexpandable lung and a possible prediction of the efficacy of chest tube drainage in patients with spontaneous pneumothorax. ⋯ Pleural manometry is critical for measurement of pleural elastance, diagnosis of an unexpandable lung and differentiation between trapped lung and lung entrapment. This usually has significant clinical implications in terms of further management of patients with pleural effusion. The paper is a comprehensive review presenting different aspects of pleural pressure measurement in clinical practice.

Observational StudyThe multidimensional nature of dyspnoea in amyotrophic lateral sclerosis patients with chronic respiratory failure: Air hunger, anxiety and fear.
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder leading to chronic respiratory failure. Few studies have investigated ALS-related dyspnoea, and none have characterised the emotional distress it inflicts. We hypothesised that ALS-related dyspnoea has a strong affective component that relates to quality of life. ⋯ ALS-related dyspnoea is intense and fear-provoking, persists during unassisted breathing between NIV sessions, and significantly impacts health-related quality of life. This study highlights the need for increased awareness of and research into ALS-related dyspnoea.

Observational StudyQuantitative assessment of erector spinae muscles in patients with Mycobacterium avium complex lung disease.
No reports exist regarding skeletal muscle involvement in patients with Mycobacterium avium complex lung disease (MAC-LD). The cross-sectional area of the erector spinae muscles (ESMCSA) reflects physical activity and can be assessed by computed tomography (CT). We investigated the relationship between ESMCSA and physiological parameters and prognosis in MAC-LD patients. ⋯ Although the prognostic impact was limited, ESMCSA was significantly associated with HRQL and prognostic physiological parameters, such as BMI and pulmonary function.
