Caregivers for people with end-stage lung disease: characteristics and unmet needs in the whole population.
End-stage lung disease (ESLD) (predominantly caused by chronic obstructive pulmonary disease and restrictive lung disease) is a significant cause of death. Little is known about community care for people with ESLD especially in the period leading to death. This paper describes demographic characteristics of caregivers, and key characteristics of the deceased irrespective of specialist service utilization. ⋯ Given the health consequences of caregiving, caregivers of people with ESLD would benefit from prospectively defining their needs given the time for which intense caregiving is provided.

Randomized Controlled Trial Multicenter StudyTiotropium and exercise training in COPD patients: effects on dyspnea and exercise tolerance.
Exercise training improves exercise tolerance in chronic obstructive pulmonary disease (COPD). Tiotropium 18 microg once daily induces sustained bronchodilation throughout the day and reduces hyperinflation, one of the pathophysiological factors contributing to exertional dyspnea in COPD patients. ⋯ Although significant improvements were observed with perceived dyspnea, compared to placebo, the addition of tiotropium to pulmonary rehabilitation did not improve the 6MWT.

ReviewImaging of pulmonary emphysema: a pictorial review.
The term 'emphysema' is generally used in a morphological sense, and therefore imaging modalities have an important role in diagnosing this disease. In particular, high resolution computed tomography (HRCT) is a reliable tool for demonstrating the pathology of emphysema, even in subtle changes within secondary pulmonary lobules. Generally, pulmonary emphysema is classified into three types related to the lobular anatomy: centrilobular emphysema, panlobular emphysema, and paraseptal emphysema. ⋯ In panlobular emphysema, HRCT shows either panlobular low attenuation or ill-defined diffuse low attenuation of the lung. Paraseptal emphysema is characterized by subpleural well-defined cystic spaces. Recent topics related to imaging of pulmonary emphysema will also be discussed, including morphometry of the airway in cases of chronic obstructive pulmonary disease, combined pulmonary fibrosis and pulmonary emphysema, and bronchogenic carcinoma associated with bullous lung disease.

Randomized Controlled TrialEffect of add-on therapy of tiotropium in COPD treated with theophylline.
Although combination therapy with bronchodilators is recommended for chronic obstructive pulmonary disease (COPD), there is insufficient evidence for the efficacy of some combinations of long-acting bronchodilators. ⋯ Addition of tiotropium therapy to theophylline treatment can improve dyspnea and pulmonary function in COPD. Although this study did not assess whether there was any benefit of adding theophylline to patients treated with tiotropium, tiotropium can be a useful addition in COPD already treated with theophylline.

ReviewMedication adherence issues in patients treated for COPD.
Although medical treatment of COPD has advanced, nonadherence to medication regimens poses a significant barrier to optimal management. Underuse, overuse, and improper use continue to be the most common causes of poor adherence to therapy. An average of 40%-60% of patients with COPD adheres to the prescribed regimen and only 1 out of 10 patients with a metered dose inhaler performs all essential steps correctly. ⋯ While use of a combined inhaler may facilitate adherence to medications and improve efficacy, pharmacoeconomic factors may influence patient's selection of both the device and the regimen. Patient's health beliefs, experiences, and behaviors play a significant role in adherence to pharmacological therapy. This manuscript reviews important aspects associated with medication adherence in patients with COPD and identifies some predictors of poor adherence.
