    Abstract Objective: To compare physical activity levels and sedentary behavior between individuals working in the office and those working from home, with the aim of elucidating the potential implications on employees' health.
    Methods: We used triaxial accelerometers to assess the physical activity levels of 94 white-collar employees from a large-scale manufacturing company in Japan. They were instructed to wear the accelerometers during their working hours, which included the commuting time on work-in-office days.
    Results: The mean energy expenditure on work in office was 426 kcal for individuals, while it was 228 kcal on work from home (P < 0.01). In addition, not including commuting, the time spent sedentary on work-from-home days was higher than that on work-in-office days by 20 minutes.
    Conclusions: Work from home decreases physical activity and increases sedentary time compared with work in office.

    Abstract Perineurioma is a relatively rare tumor with an occasionally difficult differential diagnosis. A 63-year-old woman underwent esophagogastroduodenoscopy, which revealed a 15 mm, slightly faded, flat, and elevated lesion in the gastric body. Biopsy revealed a bundle-like proliferation of spindle-shaped cells; however, the diagnosis was unconfirmed. Endoscopic submucosal dissection was performed for diagnosis and treatment. Histopathological examination of the lesion revealed cell proliferation with short spindle-shaped and oval nuclei and little atypia in the lamina propria. Immunohistochemical examination indicated a perineurioma. Thus, when spindle-shaped cells are found on biopsy, it is necessary to consider the possibility of perineurioma.

    Abstract Although Japan has been a signatory to the Framework Convention on Tobacco Control (FCTC) since 2004, progress in translating the recommendations into national policy has been limited, especially regarding the protection of non-smokers from secondhand smoke (SHS).So far, it has been recommended to install designated smoking rooms in workplaces to prevent exposure to SHS in Japan. We examined the typical designated smoking room that was installed according to "The guidelines for smoking control in workplaces" introduced by the Ministry of Health, Labour and Welfare in 2003. It is revealed that such recommended smoking rooms are not functioning. It is necessary to implement smoke-free policy in order to prevent SHS in workplaces.

    Abstract Secondhand smoke is the major health risk among non-smokers. It is estimated that more than 6,800 non-smokers who are exposed to secondhand smoke die every year in Japan. WHO Framework Convention on Tobacco Control requires all the governments to implement comprehensive smoking ban in order to protect non-smokers' health. Many countries and municipal offices implemented comprehensive smoking ban in workplaces and public spaces including restaurants and bars. The number of patients of acute coronary syndrome and respiratory disease rapidly decreased in those countries. These facts should be announced to the people and policy makers where comprehensive smoking ban has not implemented yet in order to protect non-smokers' health.

    Abstract Objective: We evaluated work intensity, exercise tolerance, and mental health among workers with heart disease and assessed the relationship between return to work (RTW) status and changes in mental health 3 months post-discharge.
    Methods: Patients were enrolled from 2014 to 2019. Data were collected on admission and 3 months post-discharge. Mental health was assessed using the Hospital Anxiety and Depression Scale. Jobs were defined as "reasonable workload (RW)" or "over workload (OW)" based on metabolic equivalents.
    Results: Twenty-six patients responded (81.3%). RTW after 3 months was higher in the RW group (100%) than in the OW group (63.6%). Mental health in the OW group significantly deteriorated compared with baseline and was higher than that in the RW group.
    Conclusions: Patients whose work intensity was higher than their exercise tolerance had worsened mental health 3 months post-discharge.

    Abstract Objective: The Health Promotion Act was revised in 2018 and prohibits smoking inside taxis and buses. However, there is no regulation for smoking in the business vehicles of companies or private cars. This paper examined exposure to secondhand smoke in vehicles with digital dust monitors.
    Material and methods: A cigarette was smoked inside of a five-seat car, and particulate matter 2.5 (PM
    Results: The concentration of PM
    Discussion and conclusion: To prevent exposure to secondhand smoke, smoking should not be allowed inside any vehicle when non-smokers are present.

    Abstract Little is known about the factors related to return to work (RTW) in patients with peri-operative lung cancer (LC). This study aimed to investigate whether pre-operative physical performance is associated with early RTW in patients with peri-operative LC. A total of 59 patients who wished to resume work after lung resection surgery were included and were divided into three groups: early RTW (within 14 days after discharge), delayed RTW (within 15-90 days), and non-RTW (failure of RTW within 90 days). The early RTW group had significantly lower scores on the modified Medical Research Council dyspnea scale (mMRC) and significantly higher scores on the Euro Quality of Life 5-Dimension 3-Level (EQ-5D-3L) than the non-RTW group. Multivariate logistic regression analysis showed that EQ-5D-3L scores were significantly associated with early RTW, and mMRC scores and knee extensor strength tended to be associated with early RTW. Better pre-operative quality of life, mild dyspnea, and greater lower limb muscle strength tended to be associated with early RTW in patients with peri-operative LC.

    Abstract Purpose: Surgical smoke is generated during the cauterization, coagulation, and incision of biological tissues by electrocautery, ultrasonic coagulation, incising devices, and lasers. Surgical smoke comprises water, water vapor, steam, and some particulate matter, including bacteria, viruses, cell fragments, and volatile organic compounds, which can pose health risks to the operating room personnel. In this study, we measured the concentration of particulate matter 2.5 (particles with a diameter of ≤ 2.5 μm) in surgical smoke.
    Methods: We used digital dust counters for real-time monitoring of particulate matter 2.5 generated intraoperatively in breast and gastrointestinal surgeries performed at our hospitals between 2019 and 2020.
    Results: Concentrations of particulate matter 2.5 were measured in surgical smoke generated when performing 14 different surgeries. Immediately after electrocautery, the concentration of particulate matter 2.5 increased to 2258 μg/m
    Conclusion: Surgical smoke poses potential health risks to operating room personnel by contaminating their breathing zone with high concentrations of particulate matter 2.5. A local exhaust ventilation system is needed to reduce exposure.
