Purpose: We estimated the static and dynamic effects of promotion to managerial positions on mental health and satisfaction using the recent estimation method; we addressed the gap in extant research by considering the heterogeneity in treatment timing to reconfirm evidence regarding the causal effects of promotion.
Methods: We used a modified estimation method of two-way fixed effects recommended by (Callaway and Sant'Anna, J Econom 225:200-230, 2021). To check for robustness, we compared the analyses using propensity sample matching, an alternative treatment timing heterogeneity-robust analysis, and a normal two-way fixed effects event study.

The purpose of the present study is to contribute to the establishment of a standard method for evaluating the adverse effects of nanomaterials by intratracheal administration. Low and high doses of multi-walled carbon nanotubes (MWCNTs) were administered to rats in a single administration or the same final dose as the single administration but divided over four administrations. Bronchoalveolar lavage examination on day 14 showed an inflammatory reaction and cytotoxicity in the lung, generally greater at the higher dose, and tending to be greater in the rats with four administrations at both the low and high doses.

Purpose: Prolonged sitting time (ST) has been suggested as a risk factor for CVD. Particularly, occupational ST (OST) is determined by occupation-specific activities and can impact the health status of workers. However, there is limited information on the impact of OST across different occupations among Japanese workers.

Background: Contextual memory loss of emotional events plays a critical role in depression psychopathology. Individuals with depression, clinical or subclinical, exhibit enhanced and impaired memory for emotionally negative stimuli and context in an event, respectively. This suggests that contextual encoding may fail because of attentional interference caused by concurrent negative stimuli, possibly leading to contextual memory loss as a depression risk.

Isocyanates are used as raw materials for polyurethane foams, paints, and building materials. The isocyanates can cause acute adverse health effects such as irritation of the respiratory tract, skin, and eyes, and induce asthma and sick house syndrome. However, investigations into the potential sources and risk assessments of indoor isocyanates are limited.

Background: The COVID-19 pandemic and associated restrictions on human activities have greatly changed lifestyles, which might have deteriorated the cardiometabolic profile.
Objective: This study aimed to examine the effect of the COVID-19 pandemic on the incidence of cardiometabolic risk factors among Japanese workers in fiscal years (FY) 2020 and 2021 compared with the prepandemic period.
Method: This study comprised an average of 71 025 employees in Japan who underwent annual health check-ups for at least two successive years from 2015 to 2021.

Background: Antibiotics are often overprescribed in children in general practice. We investigated whether the availability of C-reactive protein point-of-care testing (CRP POCT) in daily practice and general practitioner (GP) education reduces antibiotic prescribing for children with acute infections and whether GP education has a long-term effect on antibiotic prescribing.
Methods: This was a randomized controlled intervention study with randomization at the GP practice level.

Background: Worsening loneliness and social isolation during the COVID-19 pandemic have become serious public health concerns worldwide. Despite previous research reporting persistent loneliness and social isolation under repeated emergency declarations and prolonged pandemics, long-term studies are needed to identify the actual conditions of loneliness and social isolation, and the factors that explain them.
Objective: In this study, 3 web-based surveys were conducted at 1-year intervals during the 2 years after the first state of emergency to examine changes in loneliness and social isolation and the psychosocial factors associated with them in the Japanese population.

Cortisol levels in fingernail samples are known to represent cumulative hormone levels. However, findings on the association between fingernail cortisol and perceived stress have been inconsistent. Since the effect of confounding factors cannot be excluded in cross-sectional studies, this study longitudinally examined the effects of perceived stress and negative life events on changes in fingernail cortisol levels over a period of six months.
