Double‐ring sign in granulocyte colony‐stimulating factor‐induced vasculitis Open
Key message If a double‐ring sign is found in contrast‐enhanced computed tomography, this should raise concern not only for Takayasu arteritis, but also for granulocyte colony‐stimulating factor‐induced vasculitis.

Surfactant protein D: A useful biomarker for distinguishing COVID‐19 pneumonia from COVID‐19 pneumonia‐like diseases Open
Introduction Computed tomography is useful for the diagnosis of coronavirus disease (COVID‐19) pneumonia. However, many types of interstitial lung diseases and even bacterial pneumonia can show abnormal chest shadows that are indistinguish…

Prognostic significance of antifibrotic agents in idiopathic pulmonary fibrosis after initiation of long-term oxygen therapy Open
Background: Idiopathic pulmonary fibrosis (IPF) is a fatal and progressive interstitial lung disease with varying degrees of hypoxemia. Long-term oxygen therapy (LTOT) is frequently used to treat hypoxemia, however the prognostic factors f…

Relative bradycardia is a useful clinical feature for distinguishing COVID-19 from influenza Open
We retrospectively examined febrile (>38.3°C) adult patients with microbiologically confirmed coronavirus disease (COVID-19) (n=48) or influenza (n=63). The median pulse rate (/min)/body temperature (°C) ratio was significantly lower for C…

Orbital apex syndrome associated with intraorbital metastasis of lung cancer Open
Key message In lung cancer patients, brain metastasis is often suspected when neurological symptoms appear; however, if ptosis, ocular motility disorder or optic nerve disorder is observed, it is important to identify and treat the orbital…

Impact of sarcopenia on chemotherapy‐triggered exacerbation of interstitial lung disease in patients with non‐small cell lung cancer Open
Background While recent evidence has suggested that sarcopenia could predict chemotoxicity, its association with chemotherapy‐triggered interstitial lung disease (ILD) exacerbations has yet to be investigated. Thus, the present study sough…

Glasgow prognostic score for prediction of chemotherapy‐triggered acute exacerbation interstitial lung disease in patients with small cell lung cancer Open
Background Predicting the incidence of chemotherapy‐triggered acute exacerbation of interstitial lung disease (AE‐ILD) in patients with lung cancer is important because AE‐ILD confers a poor prognosis. The Glasgow prognostic score (GPS), w…

Glasgow Prognostic Score predicts chemotherapy‐triggered acute exacerbation‐interstitial lung disease in patients with non‐small cell lung cancer Open
Background Interstitial lung disease (ILD) in patients with non‐small cell lung cancer (NSCLC) worsens the prognosis for overall survival (OS) due to chemotherapy‐triggered acute exacerbation (AE)‐ILD. The Glasgow Prognostic Score (GPS), w…

Corticosteroids for hospitalized patients with mild to critically-ill COVID-19: A multicenter, retrospective, propensity score–matched study Open
Background: Corticosteroids use in coronavirus disease 2019 (COVID-19) is controversial, especially in mild to severe patients who do not require invasive/noninvasive ventilation. Moreover, many factors remain unclear regarding the appropr…
