Does 1-minute walk test predict results of 6-minute walk test in patients with idiopathic pulmonary fibrosis?

Background: The six-minute walk test (6MWT) is a readily available tool used to evaluate functional capacity in patients with idiopathic pulmonary fibrosis (IPF). However, it is often logistically challenging to perform in the context of a busy clinical practice. We sought to investigate if the 1MWT distance (1MWD) predicts the 6MWT distance (6MWD), and if an abbreviated walk could accurately predict outcomes in IPF patients.

Impact of OSA on cardiovascular events after coronary artery bypass surgery.

Background: The impact of OSA on new cardiovascular events in patients undergoing coronary artery bypass graft (CABG) surgery is poorly explored.

Methods: Consecutive patients referred for CABG underwent clinical evaluation and standard polysomnography in the preoperative period. CABG surgery data, including percentage of off-pump and on-pump CABG, number of grafts, and intraoperative complications, were collected.

A rare cause of hemoptysis: benign sugar (clear) cell tumor of the lung.

A case of benign sugar (clear) cell tumor of the lung with an unusual clinical presentation and its evaluation with computed tomography are reported. A 48-year-old man presented with one episode of hemoptysis. Chest radiographs revealed a round nodule in the lower left lung lobe, and fiberoptic bronchoscopy was normal.
