Relationships between emphysema and airways metrics at high-resolution computed tomography (HRCT) and ventilatory response to exercise in mild to moderate COPD patients
In Chronic Obstructive Pulmonary Disease (COPD) patients, the opportunity to carry out a thoracic high-resolution CT (HRCT) scan and to perform an incremental cardiopulmonary exercise test (CPET) increases the possibility to identify the different clinical features of disease. The aim of our study was to evaluate the relationships between HRCT metrics (on emphysema by low attenuation areas-LAA% and airways by wall area-WA%) and CPET variables related to the dynamic response to exercise in terms of elastic balance (Δ rest-to-peak IC/TLC) and ventilation capacity for carbon dioxide output (VE/VCO2 slope and VE/VCO2 intercep...

The effect of N-acetylcysteine on biofilms: Implications for the treatment of respiratory tract infections
In airway infections, biofilm formation has been demonstrated to be responsible for both acute and chronic events, and constitutes a genuine challenge in clinical practice. Difficulty in eradicating biofilms with systemic antibiotics has led clinicians to consider the possible role of non-antibiotic therapy. The aim of this review is to examine current evidence for the use of N-acetylcysteine (NAC) in the treatment of biofilm-related respiratory infections. (Source: Respiratory Medicine CME)

Profile of difficult to treat asthma patients referred for systematic assessment
We determined the proportion of asthma patients under specialist care who remain difficult-to-treat and might benefit from systematic assessment. We additionally report the characteristics and indications for referral in 90 patients who received systematic assessment for difficult asthma. (Source: Respiratory Medicine CME)

Tiotropium improves lung function, exacerbation rate, and asthma control, independent of baseline characteristics including age, degree of airway obstruction, and allergic status
Many patients with asthma remain symptomatic despite treatment with inhaled corticosteroids (ICS) with or without long-acting β2-agonists (LABAs). Tiotropium add-on to ICS plus a LABA has been shown to improve lung function and reduce exacerbation risk in patients with symptomatic asthma. (Source: Respiratory Medicine CME)

Activity limitation and exertional dyspnea in adult asthmatic patients: What do we know?
Limitation of activity is the most cited symptom described by uncontrolled asthma patients. Assessment of activity limitation can be undertaken through several ways, more or less complex, subjective or objective. Yet little is known about the link between patients sensations and objective measurements.The present review reports the current knowledge regarding activity limitation and symptom perception (i.e., exertional dyspnea) in adult patients with asthma. This work is based on references indexed by PubMed, irrespective of the year of publication. (Source: Respiratory Medicine CME)

Novel variants of SERPIN1A gene: Interplay between alpha1-antitrypsin deficiency and chronic obstructive pulmonary disease
Alpha1-antitrypsin (AAT) is one of the major circulating anti-protease whose levels in circulation are raised during excessive amount of proteases, especially neutrophil elastase (NE) released during the course of inflammation. Proteolytic attack of NE on peripheral organs, more exclusively on lung parenchyma has severe consequence that may precipitate pulmonary emphysema. Normally, human body has its own molecular and physiological mechanisms to synthesize and regulate the production of anti-protease like AAT to mitigate the extent of inflammatory damage.

Improvement of physical activity after endobronchial valve treatment in emphysema patients
Bronchoscopic lung volume reduction using endobronchial valves is a promising treatment for severe emphysema patients without collateral ventilation. Physical activity is an important contributing factor for the autonomy, morbidity and mortality of these patients. (Source: Respiratory Medicine CME)

Stepping down from combination asthma therapy: The predictors of outcome
Stepping down from combination asthma therapy (inhaled corticosteroids (ICS) + long-acting β2 agonists (LABA)) is often avoided due to fear of exacerbations, which may lead to overmedication in well-controlled asthma. A better knowledge about the predictors of outcome might encourage clinicians to start stepping down more often than previously. (Source: Respiratory Medicine CME)

Comparison of endobronchial ultrasound and high resolution computed tomography as tools for airway wall imaging in asthma and chronic obstructive pulmonary disease
Airway remodeling in asthma and chronic obstructive pulmonary disease (COPD) results in bronchial wall thickening. Bronchial wall thickness (BWT) can be assessed in high-resolution computed tomography (HRCT) and endobronchial ultrasound (EBUS). (Source: Respiratory Medicine CME)

Perioperative respiratory care in obese patients undergoing bariatric surgery: Implications for clinical practice
Obesity is an increasing problem worldwide. The number of people with obesity doubled since the 1980's to affect an estimated 671 million people worldwide. Obese patients in general have an altered respiratory physiology and can have an impaired lung function, which leads to an increased risk of developing pulmonary complications during anaesthesia and after bariatric surgery (approximately 8%). Therefore the respiratory management of the bariatric surgical patient provides a number of challenges. (Source: Respiratory Medicine CME)

Management of obese patients with respiratory failure – A practical approach to a health care issue of increasing significance
In the general population, prevalence of obesity is increasing continuously. Concomitantly, a growing number of obese patients with severe illnesses presents at intensive care units (ICU). Particularly respiratory management of this patient group poses a challenge to intensive care physicians because of differences in respiratory anatomy and physiology in obese compared to non-obese individuals.Aim of this review is to present treatment options for critically ill obese patients requiring mechanical ventilation based on current studies concerning patient positioning, ventilatory regimen as well as extended therapy with veno...
