Abstract	An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near the atrioventricular node. Intraoperative pathological examination revealed that the tumor was a myxoma, and complete resection was successfully performed. However, she experienced persistent complete atrioventricular block postoperatively and required pacemaker implantation.

Abstract	Background: This study examined the association between dermatological, neurological, and bone manifestations of neurofibromatosis type 1 (NF1) and quality of life (QoL) in patients with NF1 using a nationwide database of all patients who newly claimed for medical expense subsidies in Japan from 2015 to 2019. Methods: The Japanese Ministry of Health, Labour and Welfare provided the "National Database of Designated Intractable Diseases of Japan" containing clinical and personal records ("Medical Certificates of Designated Intractable Diseases") of all patients with NF1 following approval of the study protocol. To examine the association between the severity of symptoms and QoL, multinominal logistic regression analyses were performed, adjusted for potential confounders. Results: The final study population consisted of 1,487 patients (775 females and 712 males; mean (standard deviation) age, 45.4 (17.9) years). More than 50% and nearly 45% of participants were recorded as having moderate or severe "pain/discomfort" and "anxiety/depression," respectively. The severity of neurological symptoms was significantly associated with all components of QoL, whereas the severity of dermatological symptoms was significantly associated with only moderate or severe subjective and mental health-related components of QoL, and the severity of bone lesions was associated with only moderate or severe physical health-related components of QoL. Subjective and mental health-related components of QoL tended to be deteriorated more than physical health-related components of QoL in younger and female patients. Conclusions: Severities of neurological and dermatological symptoms were significantly associated with subjective and mental health-related components of QoL, while the severity of bone symptoms was associated with only moderate and severe deterioration of physical health-related components of QoL.

Abstract	Involuntary non-regular employment is a severe inequity problem worldwide, and it may significantly affect the mental health of employees. The present study aimed to examine the relationship between employment type and mental health. Additionally, the characteristics of involuntary non-regularly employed workers were explored. An online-based cross-sectional study was conducted in Japan, and 1566 participants were included in the data analysis. The eligible participants were divided into four categories: regularly employed (n = 1092), voluntary (n = 134), average (n = 233) and involuntary (n = 107) non-regularly employed individuals, respectively. Involuntary non-regular employment was associated with greater lack of vigour, anger-irritability, fatigue, anxiety, and depression. It was higher among women, those who were single or had no childcare, and those who had lower personal income or shorter working hours, or who tended not to practice relaxation activities. Lower personal income was associated with a risk of anxiety and depressive symptoms. Those individuals experiencing involuntary non-regular employment had a higher risk of poor mental health; subgroup analysis showed that this was particularly true among men. Both encouragement of employment stability via policy reform and workplace mental health support for involuntary non-regularly employed individuals are urgent health concerns.

Abstract	Background: Students and workers have been subjected to increased levels of psychological distress due to the quarantine policy and containment measures during the COVID-19 pandemic. This scoping review aimed to present an overview of published evidence regarding formal and informal help-seeking intentions/behaviors for non-mental health-related issues as well as mental health-related issues among students and workers during the pandemic. Methods: In June 2022, we searched MEDLINE, APA PsycNet, and CINAHL for articles reporting the state of help-seeking intentions/behaviors among students and workers during the pandemic. Peer-reviewed original articles published in English were selected. Results: In total, 150 articles were identified, and 12 articles were selected for final analysis after removing articles that met the exclusion criteria. Three studies targeted university students, and nine targeted healthcare workers. Study settings were restricted to Western countries and China. Of the 12 studies, 11 were observational and predominantly cross-sectional studies. Two longitudinal studies using student samples suggested that university students became more reluctant to seek help from both formal and informal sources during the COVID-19 pandemic compared to before, despite the increased need for support during the pandemic. Among healthcare workers, the proportions of those who sought help from formal sources in person were low (7-26%), even among those with mental health issues, despite the increase in the need for mental health services. One randomized controlled study reported that a brief video-based intervention increased treatment-seeking intentions among healthcare workers in the intervention group compared with the non-intervention group. Conclusions: The present review revealed that, although most studies included in the final analysis were cross-sectional, intentions/behaviors to seek help from both formal and informal sources decreased among university students, even those with mental health issues. Among healthcare workers, while the frequency of help-seeking from formal sources in person was low, a brief online intervention was suggested to be useful for promoting help-seeking from formal sources. During public health crises such as the COVID-19 pandemic, system and infrastructure development of online help-seeking services could potentially promote formal and informal help-seeking intentions/behaviors for diverse issues, including non-mental health-related issues, among university students and healthcare workers/providers.

Abstract	This study aimed to examine how heating affects the physical properties of a newly developed premixed calcium silicate-containing sealer (AH Plus Bioceramic Sealer; AHB), in comparison with EndoSequence BC Sealer (ES), AH Plus Jet (AH), and Pulp Canal Sealer. The setting time, flow, and film thickness were tested with or without heating at 100 °C for 30 or 60 s, in accordance with ISO6876:2012 standards. Ultrastructural and elemental analyses were performed with scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Data were analyzed using one-way analysis of variance (ANOVA) with a Tukey post hoc test (α = 0.05). All sealers exhibited significantly shorter setting time and flow after heating at 100 °C for 30 and 60 s (

Abstract	Background: This study aimed to examine population-based characteristics of non-fatal self-harm in an urban area during pre- and peri-pandemic periods of COVID-19 by sex, age, and severity of self-harm, using pre-hospital medical emergency records. Methods: We used a registry of all pre-hospital medical records of self-harm cases that occurred in Kawasaki City, Japan, between January 2018 and December 2021. Adjusted incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were calculated using Poisson regression models with the log-transformed population by year, sex, age group, and ward as an offset term. Results: During the 4-year study period, 1,534 patients were transported by ambulance due to non-fatal self-harm and were alive on arrival at the hospital. Among women, the number of non-fatal self-harm cases increased by 1.2-fold in 2021 compared with that in 2018. The incidence rate of "severe" non-fatal self-harm among men aged 19 years or younger in 2021 (IRR 4.82, 95% CI 1.25-18.65) and that among women aged 50-59 years in 2020 (IRR 2.51, 95% CI 1.06-5.95) significantly increased compared with that 2018 and 2019. The incidence rate of "mild" self-harm among women aged 20-29 years tended to be higher in 2021 than in 2018 and 2019 (IRR 1.42, 95% CI 0.95-2.12, P = 0.085). Conclusions: During the peri-pandemic period of COVID-19, the incidence rate of "severe" non-fatal self-harm among men aged 19 years or younger and women aged 50-59 years, as well as that of "mild" self-harm among women aged 20-29 years, sharply increased compared with that during the pre-pandemic period. Our findings suggest that in urban areas during public health crises such as a pandemic, it is important to take measures to reduce the risk of non-fatal self-harm in young women, in addition to strengthening counseling and support for young women at risk for completed suicide.
