Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease that is characterized by chronic airflow limitation. Unraveling of this heterogeneity is challenging but important, because it might enable more accurate diagnosis and treatment. ⋯ Quantitative computed tomography (CT) is a promising technique, because current CT technology is able to quantify emphysema, air trapping, and large airway wall dimensions. This review focuses on CT quantification techniques of COPD disease components and their current status and role in phenotyping COPD.

Sleep apnea is a common health concern that is characterized by repetitive episodes of asphyxia. This condition has been linked to serious long-term adverse effects such as hypertension, metabolic dysregulation, and cardiovascular disease. ⋯ Animal models, which have the advantage of being free of comorbidities and/or behavioral variables (that commonly occur in humans), allow invasive measurements under well-controlled experimental conditions, and as such are useful tools in the study of the pathophysiological mechanisms of sleep apnea. This review summarizes currently available information on the cardiovascular consequences of sleep apnea and briefly describes common experimental approaches useful to sleep apnea in different animal models.

Comparative Study
Specialist palliative care is more than drugs: a retrospective study of ILD patients.
This study aimed to assess the palliative care needs of progressive idiopathic fibrotic interstitial lung disease (PIF-ILD) populations in two London ILD centres. ⋯ Despite demographic variation, the patient populations at the two hospitals experienced similar symptoms. There was use of standard pharmacological treatments with symptom benefit. Nonpharmacological interventions were seldom used and documentation of preferred place of care and preferred place of death was poor.

Pulmonary endarterectomy is the treatment of choice in chronic thromboembolic pulmonary hypertension (CTEPH). Modern pulmonary vasoactive medication (like endothelin receptor antagonists, phosphodiesterase type 5 inhibitors, and prostacyclins) is used in patients with an inoperable disease and improved prognosis. We evaluate mortality and time to clinical worsening (TtCW) in inoperable CTEPH patients during long-term follow-up. ⋯ Despite the improvement in medical treatment of inoperable CTEPH, the mortality rate is still high, and clinical worsening occurred in a substantial number of patients during a follow-up of more than 3 years.

Comparative Study
Endobronchial ultrasound plus fluoroscopy versus fluoroscopy-guided bronchoscopy: a comparison of diagnostic yields in peripheral pulmonary lesions.
Even though fluoroscopy-guided bronchoscopy has been well developed, the diagnostic yield of peripheral pulmonary lesions (PPLs) remains unsatisfying. Therefore, endobronchial ultrasound (EBUS) has been implemented recently to enhance the possibility of attaining true diagnosis. However, there are few studies that directly compare the success rate of fiber-optic bronchoscopy with fluoroscopic guidance to that of EBUS guidance in the diagnosis of PPLs in the same institute and in the same study period. The aim of this study was to compare the performance of EBUS plus fluoroscopy guidance with that of fluoroscopy-guided bronchoscopy in the diagnosis of PPLs. ⋯ Bronchoscopy under EBUS and fluoroscopy guidance improved the diagnostic yield of PPLs, especially of those smaller than 20 mm in diameter.
