Randomized Controlled Trial Comparative Study
Noninvasive assisted pressure-controlled ventilation: as effective as pressure support ventilation in chronic obstructive pulmonary disease?
Noninvasive ventilation (NIV) is being increasingly used in hypercapnic chronic obstructive pulmonary disease (COPD) patients but the most appropriate ventilation mode is still not known. ⋯ From these data, we deduce that APCV can be a better alternative to PSV for NIV in COPD patients with AHRF owing to its more beneficial physiological effects.

Inhaled corticosteroids as additional treatment in alpha-1-antitrypsin-deficiency-related COPD.
No consistent data are available regarding the effect of inhaled corticosteroids (ICS) in alpha(1)-antitrypsin-deficiency (AATD)-related COPD. Recent data report inflammatory effects of the polymers of alpha(1)-antitrypsin on the peripheral lung. ⋯ In AATD-related COPD patients (ZZ genotype) the addition of extra-fine ICS to LABAs decreases airway narrowing, mostly in the small airways, further reducing dynamic hyperinflation with a marked improvement in exercise tolerance and dyspnea, suggesting that a peripheral inflammatory process contributes to airflow obstruction in these patients.

Automatic pressure titration with APAP is as effective as manual titration with CPAP in patients with obstructive sleep apnea.
The optimal approach to initiate positive-pressure therapy in patients with obstructive sleep apnea is still debated. Current options are autotitrating positive airway pressure (APAP) or manual titration with continuous positive airway pressure (CPAP). Procedures differ by parameters and by algorithms used for adapting pressure. ⋯ Taking the sequence of titration into account, we found equal effectiveness of CPAP and APAP. Sleep quality was better with initial application of APAP - which favors attended automatic titration if only 1 titration night is possible. Both modes are comparable after 6 weeks regarding therapeutic pressure, efficacy, compliance and quality of life.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of nebulized flunisolide combined with salbutamol and ipratropium bromide in stable patients with moderate-to-severe chronic obstructive pulmonary disease.
The efficacy of nebulized corticosteroids in the prevention of exacerbation of chronic obstructive pulmonary disease (COPD) has been poorly studied. ⋯ Nebulized flunisolide is a good alternative to other inhaled corticosteroids when added to nebulized salbutamol/ipratropium bromide in the long-term treatment of moderate-to-severe COPD patients.
