Contralateral bullae/blebs are frequently found in patients who are scheduled to undergo ipsilateral video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax (PSP). ⋯ Although contralateral bullae/blebs were common in patients who underwent ipsilateral VATS for PSP and were statistically significantly associated with future pneumothorax, the annual rate of pneumothorax was 4.0% in such patients, and it decreased over time. Therefore, a conservative approach on unruptured contralateral bullae/blebs is recommended.

Prolonging life in the ICU increasingly is possible, so decisions to limit life-sustaining therapies frequently are made and communicated to patients and families or surrogates. Little is known about worldwide communication practices and influencing factors. ⋯ End-of-life communication with patients and families or surrogates varies markedly in different global regions. GEE analysis supports the hypothesis that communication may increase with ethical practice and an advance directive. Greater effort is needed to align treatment with patients' wishes.

A 52-year-old man came to the cardiac surgery clinic for pulmonary thromboendarterectomy (PTE) evaluation. He had initially appeared at an outside hospital 1 year earlier, with chest pain and shortness of breath. He had no known chronic conditions. ⋯ His anticoagulation was transitioned to enoxaparin for presumed apixaban treatment failure, and an investigation for hypercoagulable conditions was initiated. His lupus anticoagulant test result was positive, but he did not meet the criteria for antiphospholipid syndrome because he was negative for anticardiolipin and β2-glycoprotein antibodies. Assays for antithrombin III, protein C, prothrombin gene, and factor V Leiden mutations produced normal results.

Observational Study
Pick your threshold: a comparison among different methods of anaerobic threshold evaluation in heart failure prognostic assessment.
In clinical practice, anaerobic threshold (AT) is used to guide training and rehabilitation programs, to define risk of major thoracic or abdominal surgery, and to assess prognosis in heart failure (HF). AT of oxygen uptake (V.O2; V.O2AT) has been reported as an absolute value (V.O2ATabs), as a percentage of predicted peak V.O2 (V.O2AT%peak_pred), or as a percentage of observed peak V.O2 (V.O2AT%peak_obs). A direct comparison of the prognostic power among these different ways to report AT is missing. ⋯ In HF, V.O2AT%peak_pred is the best way to report V.O2 at AT in relationship to prognosis, with a prognostic power comparable to that of peak V.O2 and, remarkably, in patients with severe HF.

Prognostic prediction of nontuberculous mycobacteria pulmonary disease using a deep learning technique has not been attempted. ⋯ The DL model we developed could predict the mid-term to-long-term mortality of patients with nontuberculous mycobacteria pulmonary disease using a baseline radiograph at diagnosis, and the predictability increased with clinical information.
