Objective The incidence and clinical importance of delirium in COVID-19 have not yet been fully investigated. The present study reported the prevalence of delirium in patients with COVID-19 and identified the factors associated with delirium and mortality. Methods We performed an observational, retrospective study of patients diagnosed with COVID-19 at the Kinki-Chuo Chest Medical Center. Univariate and multivariate logistic regression analyses were used to explore delirium risk factors. Patients or Materials All consecutive patients diagnosed with COVID-19 at the Kinki-Chuo Chest Medical Center. Results We identified 600 patients [median age: 61.0 (interquartile range: 49.0-77.0) years old], of whom 61 (10.2%) developed delirium during their stay. Compared with patients without delirium, these patients were older (median age 84.0 vs. 56.0 years old, p <0.01) and had more comorbidities. Based on a multivariate analysis, age, dementia, severe disease, and lactate dehydrogenase (LDH) levels were independent risk factors for developing delirium. For every 1-year increase in age and 10-IU/L increase in LDH, the delirium risk increased by 10.8%-12.0% and 4.6%-5.7%, respectively. There were 15 (24.6%) in-hospital deaths in the group with delirium and 8 (1.6%) in the group without delirium (p <0.01). Delirium was associated with an increased mortality. Conclusion Delirium in patients with COVID-19 is prevalent and associated with poor clinical outcomes in Japan. Despite difficulties with COVID-19 patient care during the pandemic, physicians should be aware of the risk of delirium and be trained in its optimal management.

Summer-type hypersensitivity pneumonitis includes a spectrum of granulomatous lung diseases that result from the inhalation of Trichosporon species in the summer. Hot tub lung is a granulomatous lung disease caused by the inhalation of water aerosols containing non-tuberculous mycobacteria. We herein describe a case of hot tub lung that deteriorated during the winter season. Every winter, the patient's symptoms, laboratory findings and chest images worsened. Genetically identical Mycobacterium avium strains were detected in his sputum and bathtub. The circulation of bathtub water during the winter months only exacerbated his symptoms in the winter.
