Objective The causes of fever of unknown origin (FUO) vary depending on the region and time period. We herein present a study of patients with classic FUO where we investigated differences based on patient background factors, such as age and causative diseases, and changes that have occurred over time. Methods We extracted and analyzed data from the medical records of 256 patients ≥18 years old who met the criteria for classic FUO and were hospitalized between August, 1994 and December, 2012. Results The median age of the patients was 55 years (range: 18-94 years). The cause of FUO was infection in 27.7% of the patients (n=71), non-infectious inflammatory disease (NIID) in 18.4% (47), malignancy in 10.2% (26), other in 14.8% (38), and unknown in 28.9% (74). The most common single cause was human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (n=17). NIID and malignancy were more common in patients ≥65 years old than in patients <65 years old. During 2004-2012, compared to 1994-2003, infections and "other" causes were decreased, whereas NIID, malignancy, and unknown causes were increased. Conclusion FUO associated with HIV/AIDS is increasing in Japan. In addition, as in previous studies in Japan and overseas, our study showed that the number of patients in whom the cause of FUO remains unknown is increasing and exceeds 20% of all cases. The present study identified diseases that should be considered in the differential diagnosis of FUO, providing useful information for the future diagnosis and treatment of FUO.

Objectives: To determine the prevalence of burnout according to job category after the first wave of COVID-19 in Japan and to explore its association with certain factors.Methods: An online cross-sectional survey of health care workers (HCWs) from June 15 to July 6, 2020, was conducted at a tertiary hospital in Tokyo, Japan. Demographic characteristics, results of the Japanese version of the Maslach Burnout Inventory-General Survey, types of anxiety and stress, changes in life and work after the peak of the pandemic, and types of support aimed at reducing the physical or mental burden, were determined.Results: Of 672 HCWs, 149 (22.6%) met the overall burnout criteria. Burnout was more prevalent in women (OR, 3.11; 95% CI, 1.45-6.67, P = .003), anxiety due to unfamiliarity with personal protective equipment (PPE) (OR, 1.98; 95% CI, 1.20-3.27, P = .007), and decreased sleep duration (OR, 1.96; 95% CI, 1.20-3.20, P = .008). Conversely, participants who felt that the delivery of COVID-19-related information (OR, .608; 95% CI, .371-.996, P = .048) and PPE education opportunities (OR, .484; 95% CI, .236-.993, P = .048) and messages of encouragement at the workplace (OR, .584; 95% CI, .352-.969; p = .037) was helpful experienced less burnout.Conclusions: There is a need to focus on the above factors to maintain the mental health of HCWs. The delivery of COVID-19-related information and educational interventions for PPE and messages of encouragement at the workplace may be needed to reduce the mental burden.
