Quantitative computed tomography measures of skeletal muscle mass in patients with idiopathic pulmonary fibrosis according to a multidisciplinary discussion diagnosis: A retrospective nationwide study in Japan.
Idiopathic pulmonary fibrosis (IPF) is a progressive disease often accompanied by skeletal muscle wasting. We investigated whether skeletal muscle mass and muscle attenuation on computed tomography (CT) are predictors of mortality in IPF patients, using a nationwide cloud-based database and web-based multidisciplinary discussion (MDD) system. ⋯ Low ESMCSA on CT images may be a strong risk factor for all-cause mortality in IPF patients based on MDD diagnosis.

Usefulness of new diagnostic criteria for chronic hypersensitivity pneumonitis established on the basis of a Delphi survey: A Japanese cohort study.
Chronic hypersensitivity pneumonitis (CHP) is a fibrotic interstitial lung disease (ILD) caused by repeated exposure to a variety of organic particles. In November 2017, new criteria for CHP diagnosis were proposed by Morisset et al. based on a modified Delphi survey of ILD experts. However, it remains unclear whether these criteria are useful to accurately diagnose CHP. We aimed to evaluate the newly proposed CHP diagnostic criteria. ⋯ Half of the MDD-CHP patients were diagnosed with CHP using Morisset's CHP diagnostic criteria. Further investigation will be important for developing improved diagnostic criteria for CHP.

ReviewSummary of the Japanese Respiratory Society statement for the treatment of lung cancer with comorbid interstitial pneumonia.
Dramatic progress in targeted therapy and immunotherapy has been changing clinical practices in lung cancer. With the accumulation of clinical practice, it has become clear that pre-existing interstitial pneumonia (IP) could be a risk factor for drug-induced lung injury, which has enhanced awareness regarding the difficulty in treating lung cancer with comorbid IP. Unfortunately, there is only low-grade evidence in the field of lung cancer with comorbid IP, because almost all clinical trials exclude such patients. ⋯ Therefore, it is necessary to treat such cases empirically or to give up on the treatment itself. Considering these circumstances, establishing how to treat lung cancer with comorbid IP is an urgent issue. This paper is a summary of the official statement reported by the Diffuse Lung Disease/Thoracic Oncology Assembly and the Japanese Respiratory Society (JRS) in 2017, which attempts to approach lung cancer with comorbid IP systematically.

Patients with unresectable stage III non-small cell lung cancer eligible to receive consolidation therapy with durvalumab in clinical practice based on PACIFIC study criteria.
Compared to a placebo, durvalumab has been reported to significantly prolong progression-free and overall survival in patients with stage III unresectable non-small cell lung cancer (NSCLC) after chemoradiotherapy. The aim of this retrospective study was to evaluate the eligibility of patients with unresectable stage III NSCLC able to receive consolidation therapy with durvalumab in clinical practice based on the PACIFIC study criteria. ⋯ In clinical practice, approximately 70% of patients with unresectable stage III NSCLC would be eligible to receive consolidation therapy with durvalumab.

Handgrip strength measurement in patients with chronic obstructive pulmonary disease: Possible predictor of exercise capacity.
Impaired exercise capacity is one of the most important prognostic factors for patients with chronic obstructive pulmonary disease (COPD). The 6-min walk test (6MWT) is a widely used method for assessing exercise capacity in patients with COPD. However, the 6MWT requires considerable effort from patients. Therefore, a less physically demanding, but also noninvasive, method is warranted. The objective of this study was to determine the predictors of the 6MWT distance (6MWD) in patients with COPD. ⋯ We found that HGS was significantly correlated with the 6MWD compared with spirometric measurements or respiratory muscle strength parameters in Japanese patients with COPD, suggesting that HGS could be a simple and noninvasive predictor of the 6MWD in patients with COPD.
