TL;DR: The National Lung Screening Trial (NLST) is a randomized multicenter study comparing low-dose helical computed tomography with chest radiography in the screening of older current and former heavy smokers for early detection of lung cancer.

TL;DR: Results show that narrowing and disappearance of small conducting airways before the onset of emphysematous destruction can explain the increased peripheral airway resistance reported in COPD.

TL;DR: The major findings of this investigation in the 68 subjects were that minimum airway area was significantly smaller in apneic compared with normal subjects and occurred in the retropalatal region, and thickness of the lateral pharyngeal muscular walls rather than enlargement of the parapharyngeAL fat pads was the predominant anatomic factor causing airway narrowing in Apneic subjects.

TL;DR: A consensus update on the role of CT angiography in the diagnostic approach to PE is proposed, with the aim of reducing the number of unnecessary CT pulmonary angiograms being obtained in patients who are unlikely to have PE.

TL;DR: The upper airway was significantly smaller in apneic than normal subjects, especially at the retropalatal low and retroglossal anatomic levels, and the action of theupper airway dilator muscles balanced the effects of negative intraluminal pressure.
