Objective: Although the health benefits of playing sports are well-known, the association between watching sports and health is not well understood. We examined the longitudinal association of watching sports with 20 different health and well-being outcomes.

Methods: Three-wave cohort data from 6327 adults (4851 workers) in the Meiji Yasuda LifeStyle study were used to draw causal inferences.

Background: The association of working from home (WFH) with physical activity (PA) and sedentary behavior (SB) has been explored; however, this association during periods without stringent measures to combat coronavirus disease 2019 is undercharacterized. Particularly, few studies have evaluated the potential effect modification on its associations. Therefore, this study aimed to investigate the associations of WFH frequency with accelerometer-measured PA and SB, along with its effect modifiers, among Japanese white-collar workers during the later pandemic period.

Article Synopsis
  • Small companies often lag behind larger corporations in health promotion initiatives, creating a need for effective strategies to improve their health and productivity management.
  • The study focuses on a public-private partnership in Yokohama City, Japan, where life insurance representatives, acting as "Linkworkers," assisted small enterprises in obtaining health-related certifications and implementing health programs.
  • The initiative saw 71 Linkworkers visit 500 companies, with 224 firms receiving certification, indicating a positive impact on promoting health management in smaller enterprises.

Background: The novel coronavirus disease 2019 (COVID-19) pandemic may have reduced opportunities for engaging in physical activity (PA) and increased sedentary behavior (SB) among workers. However, most previous studies used self-reported assessments. This study aimed to examine the changes in accelerometer-measured PA and SB from before to after COVID-19 outbreak among Japanese workers.

We aimed to verify whether the intravitreal injection of small molecule compounds alone can create photoreceptor cells in mouse models of retinal degeneration. Primary cultured mouse Müller cells were stimulated in vitro with combinations of candidate compounds and the rhodopsin expression was measured on day 7 using polymerase chain reaction and immunostaining. We used 6-week-old N-methyl-N-nitrosourea-treated and 4-week-old rd10 mice as representative in vivo models of retinal degeneration.

Thymic carcinoma (TC) presenting with cardiac tamponade has a poor prognosis because of the difficulty in controlling malignant pericardial effusion using conventional chemotherapy. Lenvatinib, a multitargeted kinase inhibitor of vascular endothelial growth factor receptor and other kinases, has recently been proven effective against TC. As the inhibition of vascular endothelial growth factor signaling is effective in malignant pericardial effusion, lenvatinib may also be effective in TC presenting with cardiac tamponade.

Background: Moderate- to vigorous-intensity physical activity (PA) may reduce the risk of dementia; however, few studies have examined the effects of PA intensity on dementia risk.

Objective: To prospectively examine the dose-response relationship of PA intensity with the incidence of suspected dementia in community-dwelling older adults.

Methods: We conducted a baseline mail survey with an 8-year follow-up of 3,722 older adults in Japan.

Objective: Previous studies have reported opposite effects of occupational or non-occupational physical activity (PA) and sedentary behavior (SB) on health outcomes. However, no study has investigated the relationship between domain-specific movement behaviors and cardiometabolic health (CMH) among office workers, considering the compositional nature of time-use data. We investigated the associations of accelerometer-measured PA and SB for each domain (working time, non-working time on workday, and non-workday) with CMH indicators among office workers, using compositional data analysis.

A 2-biphenylacetylene was fixed into a specific conformation within the confined cavity of a hollow cage, where it underwent a regioselective spirocyclization in the presence of an electrophile. A 5-endo-dig cyclization proceeded selectively in the cage, which stands in sharp contrast to the 6-endo-dig cyclization that normally occurs in common organic media. The folded conformation adopted by the substrate within the cage was examined by H NMR spectroscopy and X-ray crystallographic analysis.

Frailty might be useful to identify older drivers who are at risk for traffic crashes. We aim to examine the association between pre-frailty/frailty defined by the Kihon Checklist (KCL) and the involvement of traffic crashes and clarify whether some domains of the KCL are associated with traffic crashes. This cross-sectional study analyzed data from 2,208 Japanese community-dwelling older drivers aged ≥ 65 years in Kasama City, who participated in our postal survey in November 2019.

Background: This study investigated whether daily physical activity of older adults, combined with social relationships, is associated with the risk of sleep disorder. Further, it determined whether a high level of one variable with a low level of the other, leads to a significantly lower risk of sleep disorder than low levels of both.

Methods: The sample comprised 1339 community-dwelling older Japanese adults: 988 in Study 1 and 351 in Study 2.

Paraneoplastic neurological syndrome (PNS) is associated with malignancies, such as small-cell lung cancer. However, patients with non-small cell lung cancer (NSCLC) rarely develop PNS. We herein report a 72-year-old man with NSCLC who developed disturbance of consciousness on the day of initiation of treatment with an immune checkpoint inhibitor.

A 63-year-old female was admitted to our hospital with history of persistent dyspnea. Right pleural effusion and ovarian tumor were discovered, but here were no significant findings on thoracoscopy under local anesthesia. The pleural effusion was suspected to be secondary to Meigs' syndrome, and a diagnosis of endometriotic ovarian cyst was made.

Pseudo-progression is a phenomenon induced by treatment with immune checkpoint inhibitors and is characterized by an increase in tumor size or the appearance of new lesions, followed by tumor regression. However, life-threatening conditions, such as cardiac tamponade, can develop in such patients. We herein report on a 69-year-old man with lung adenocarcinoma who developed cardiac tamponade as a manifestation of pseudo-progression induced by treatment with atezolizumab combined with cytotoxic chemotherapy.

Retinopathy of prematurity (ROP), a vascular proliferative disease affecting preterm infants, is a leading cause of childhood blindness. Various studies have investigated the pathogenesis of ROP. Clinical experience indicates that oxygen levels are strongly correlated with ROP development, which led to the development of oxygen-induced retinopathy (OIR) as an animal model of ROP.
