COPD is a leading cause of mortality. ⋯ An MLMP-COPD model outperformed four existing models for predicting all-cause mortality across two COPD cohorts. Performance of machine learning was similar to that of traditional statistical methods. The model is available online at: https://cdnm.shinyapps.io/cgmortalityapp/.

Silicosis is rapidly emerging in high-income countries in relation to the replacement of natural stone with artificial stone, especially in the manufacturing and installation of kitchen and bathroom countertops. Progression of this form of silicosis following the cessation of exposure is unknown. ⋯ Artificial stone silicosis rapidly progresses to PMF even following exposure cessation, and a significant percentage of patients experience a very rapid decrease in lung function.

Fatigue is commonly reported by ARDS survivors, but empirical data are scarce. ⋯ During the first year following ARDS, more than two-thirds of survivors reported clinically significant fatigue symptoms. Due to frequent co-occurrence, clinicians should evaluate and manage survivors' physical, cognitive, and mental health status when fatigue is endorsed.

A physiological approach to the analysis of hemodynamic data in pulmonary hypertension (PH) has the advantage of reducing the large number (well over 100) of potential causal illnesses into four simple mechanisms. A fifth condition is composed of mixtures of the four basic mechanisms. This approach was beautifully described by Paul Wood, the great cardiologist whose name is given to the units of pulmonary vascular resistance (PVR), Wood units. ⋯ Some cases also need left ventricular end diastolic pressure (LVEDP). Other data contributing to analysis will be discussed in each condition. A key to avoiding mistakes is to always remember that PH is simply an elevation in pressure and is not inherently diagnostic of cause.

Multicenter Study
Patient versus Clinician Perspectives on Communication about Results of Lung Cancer Screening: A Qualitative Study.
In the incidental pulmonary nodule and breast cancer screening settings, high-quality patient-centered communication can improve adherence to evaluation and mitigate patient distress. Although guidelines emphasize shared decision-making before lung cancer screening, little is known about patient-clinician communication after lung cancer screening. ⋯ Tension exists between clinicians' interest in efficiency of results notification by letter in low-risk cases and patients' need to understand and be reassured about screening results, their implications, and the plan for subsequent screening or nodule evaluation-even when clinicians did not perceive results as concerning. Brief conversations to discuss lung cancer screening results may improve patient understanding and satisfaction while reducing distress.
