Randomized Controlled Trial
Effectiveness of controlled breathing techniques on anxiety and depression in hospitalized COPD: a randomized clinical trial.
Anxiety and depression are prevalent comorbidities in patients with COPD. Breathing techniques can improve anxiety and depression in patients hospitalized for COPD exacerbation. ⋯ Controlled breathing exercises improve anxiety and depression in patients hospitalized for COPD exacerbation. (ClinicalTrials.gov NCT01826682).

Multicenter Study Observational Study
Importance of inhaler device use status in the control of asthma in adults: ASIT (Asthma Inhaler Treatment) Study.
Proper education and training in correct inhalation technique has been reported to have a substantial role in the achievement of optimal therapeutic benefit and asthma control. The present study was designed to evaluate inhaler technique and the role of education in relation to asthma control among patients with persistent asthma in Turkey. ⋯ Close follow-up with repeated checking of the patient's inhaler technique and correction of errors each time by a physician seem to be associated with a significant decrease in the percent of patients who make basic errors in inhalation maneuvers and device-independent errors, and with better control of persistent asthma.

Observational Study
Arterial stiffness measured by carotid femoral pulse wave velocity is associated with disease severity in chronic obstructive pulmonary disease.
Patients with COPD face an increased risk of cardiovascular disease and increased cardiac mortality. Carotid femoral pulse wave velocity (cf-PWV) is a validated measure of arterial stiffness, a well recognized predictor of adverse cardiovascular outcomes, and offers higher predictive value than classical cardiovascular risk factors. We investigated the association between COPD and arterial stiffness using cf-PWV as a noninvasive technique. ⋯ Our results suggest that arterial stiffness is increased in subjects with more severe and advanced COPD than in those with mild to moderate COPD. Air flow limitation and hypoxemia may induce increased arterial stiffness in COPD patients.

Randomized Controlled Trial
POLYSOMNOGRAPH CHART VIEW BY PATIENTS: A NEW EDUCATIONAL STRATEGY TO IMPROVE COMPLIANCE IN SLEEP APNEA THERAPY.
CPAP is currently the treatment of choice for obstructive sleep apnea syndrome, but therapy adherence is poor. Many educational trials have been proposed to increase CPAP adherence. We tested the hypothesis that polysomnograph chart viewing by patients would improve CPAP adherence. ⋯ Polysomnograph chart viewing by obstructive sleep apnea patients can increase CPAP adherence, as evaluated by rate of return for the follow-up visit and mean nightly CPAP use.

Comparative Study
A comparison of leak compensation during pediatric non-invasive positive pressure ventilation; a lung model study.
Ventilators used for noninvasive ventilation (NIV) must be able to synchronize in the presence of system leaks. We compared the ability of 7 ICU ventilators and 3 dedicated NIV ventilators to compensate for leaks during pediatric NIV. ⋯ Leak compensation in NIV for pediatric use can partially compensate for leaks, but varies widely among ventilators, patient weights, and lung mechanics.
