Chronic cough (CC) of 8 weeks or more affects about 10% of adults and may lead to expensive treatments and reduced quality of life. Incomplete diagnostic coding complicates identifying CC in electronic health records (EHRs). Natural language processing (NLP) of EHR text could improve detection. ⋯ NLP successfully identified a large cohort with CC. Most patients were identified through NLP alone, rather than diagnoses or medications. NLP improved detection of patients nearly sevenfold, addressing the gap in ability to identify and characterize CC disease burden. Nearly all cases appeared to be managed in primary care. Identifying these patients is important for characterizing treatment and unmet needs.

The eighth edition of nodal classification for non-small cell lung cancer (NSCLC) is defined only by the anatomical location of metastatic lymph nodes. ⋯ The nS classification could be used to provide a more accurate prognosis for patients with resected NSCLC. The nS is worth taking into consideration when defining nodal category in the forthcoming ninth edition of the staging system.

Right ventricular (RV) dysfunction is associated with poorer outcomes in heart failure with preserved ejection fraction (HFpEF). Although female subjects are more likely to have HFpEF, male subjects have worse prognosis and resting RV function. The contribution of dynamic RV-pulmonary arterial (RV-PA) coupling between sex and its impact on peak exercise capacity (VO2) in HFpEF is not known. ⋯ Male patients with HFpEF were more compromised regarding dynamic RV-PA uncoupling and reduced peak VO2 compared with female patients. This finding was driven by both RV contractile impairment and afterload mismatch. In contrast, female patients with HFpEF had preserved RV-PA coupling during exercise and better peak exercise VO2 compared with male patients with HFpEF.

Few data are available on the long-term course and predictors of quality of life (QoL) following acute pulmonary embolism (PE). ⋯ German Clinical Trials Registry (Deutsches Register Klinischer Studien: www.drks.de); No.: DRKS00005939.

A 63-year-old, non-smoking Asian woman presented to our hospital due to abnormal findings on chest radiography. She had no history of dust exposure. Chest radiography and CT imaging showed patchy ground-glass attenuation (GGA) in the bilateral lower lung lobes, a ground-glass nodule in the right lower lung lobe (diameter, 9.8 mm), and some thin-walled cysts in both lungs (Fig 1). ⋯ Simultaneously, the lung background showed diffuse lymphocytic infiltration in the alveolar septum and peribronchovascular interstitium (Fig 2). There were no symptoms suggestive of autoimmune diseases such as dryness, arthralgia, skin rash, or fever. The patient was followed up without treatment for the interstitial lung disease.
