Aim: The coronavirus disease (COVID-19) pandemic has caused significant disruptions in various aspects of daily life. The Japanese Government declared a state of emergency in April 2020, which resulted in reduced physical activity. This study investigated the impact of these lifestyle changes by generation among outpatients with cardiovascular disease (CVD).

Methods: In autumn 2020, we conducted a questionnaire survey of 1,156 CVD outpatients who visited the Department of Cardiology at our institution. The survey collected data on physical activities and changes in daily behaviors over the course of the COVID-19 pandemic. Participants were classified into 3 age groups: middle-aged (n=114, ≤64 years old), semi-old (n=330, aged 65-74 years old), and old (n=712, ≥75 years old). The number of steps per day and sedentary time per day were compared between autumn 2019 and 2020, over the course of the pandemic.

Results: In autumn 2020, the number of steps per day was significantly decreased and sedentary time significantly increased in all age groups compared to the pre-pandemic levels. However, there were no significant differences in the extent of changes in steps per day or sedentary time over the study period across all age groups. Regarding changes in daily behaviors, only the old-age group reported a decline in volunteering and reduced utilization of daycare services.

Conclusions: The COVID-19 pandemic has resulted in changes in daily activities and lifestyles across all age groups. Because lifestyle patterns differ across generations, it may be necessary to implement age-specific interventions and procedures.

Aim: This study aimed to investigate the relationship between depressive tendencies and oral diadochokinesis (ODK) in 24 older adults living in a private residential nursing home. ODK is an indicator of the oral function.

Methods: Depressive tendencies were assessed using the Geriatric Depression Scale 5, with scores of two or higher indicating probable depression. ODK was measured across four syllable tasks (/pa/, /ta/, /ka/, and /pataka/), which were evaluated using coefficient of variation (CV) values. Low CV values indicate superior performance. Potential confounders, including the cognitive function, sleep status, body mass index, instrumental activities of daily living, and physical function, were controlled.

Results: Five participants (20.8%) experienced depression. Individuals with depressive tendencies demonstrated significantly poor ODK performance (higher CV) in the /ta/ task and a marginally significant difference in the /ka/ task. No significant differences were observed between /pa/ and /pataka/.

Conclusions: These findings suggest a link between depressive tendencies and reduced proficiency in specific ODK tasks among older nursing home residents. This finding implies that a decline in the oral function in articulating /ta/ and /ka/ syllables may precede other common depressive symptoms. Furthermore, depression monitoring could be a valuable tool for early detection of the oral function in this population, enabling timely interventions.

Purpose: The present multicenter randomized controlled trial explored the effectiveness of a person-centered care program (intervention group) and a dementia-type-specific program (control group) for nurses in acute-care hospitals.

Methods: Seven hospitals in Prefecture A were randomly allocated to two groups (an intervention group and a control group), and a study of these groups was conducted from July 2021 to January 2022.

Results: A total of 158 participants were included in the study: 58 in the control group and 100 in the intervention group. In a comparison of assessment values immediately after the course, three months later, and six months later for both the intervention and control groups, "expertise in dementia nursing," "medical expertise in dementia, " and "confidence in nursing older people with dementia" were all significantly higher than before the course. Significant improvements in the intervention group's "knowledge of dementia" and "sense of dignity" on the ethical sensitivity scale were found immediately after the course compared to baseline, three months later, and six months later and were also significantly greater than the control group in terms of the amount of change. In the control group's "unique care tailored to cognitive function and the person," there were significant improvements in the ratings immediately after the course and three and six months after the course compared to baseline, with significantly greater amounts of change than in the intervention group.

Conclusion: The person-centered care program for nurses led to improvements in the knowledge about dementia and awareness of the dignity of ethical sensitivity. In addition, the type of dementia program had a significant influence on medical knowledge and unique care tailored to the cognitive function and the individual patient. Further outcome evaluations of physical restraint rates as a quality of care in nursing practice are needed.

The epigenome can adequately regulate the on/off states of genes in response to external environmental factors and stress. In recent years, it has been observed that the epigenome, which is modulated through DNA methylation, histone modifications, and chromatin remodeling, changes with age. Alterations in the epigenome lead to the loss of cell-specific epigenome/identity, which in turn triggers a decline in tissue function. In mammals, postnatal epigenomic variations are not only caused by metabolic diseases, such as diabetes or DNA damage, but also by social stress and infectious diseases. Unlike Genome-Wide Association Studies (GWAS), dynamically changing epigenomes, along with their cellular roles, need to be established as objective biomarkers in conjunction with various biological signals, such as walking speed, brain waves, and clinical data. The biological age/aging clock, determined by methylated DNA, has attracted attention, and calorie restriction not only slows the progression of aging, but also seems to suppress it. However, as indicated by gene expression analysis in aging mice, aging is not a linear model, but is represented by nonlinear dynamic changes. Consequently, the development of experimental models and analytical methods that enhance temporal resolution through time-series analysis, tailored to spatial resolution, such as cell distribution and organ specificity, is progressing. Moreover, in recent years, in addition to anti-aging efforts targeting epigenomic variations, global attention has increasingly focused on research and development aimed at rejuvenating treatments, thus leading to the birth of many biotech companies. Aging Hallmarks such as inflammation, stem cells, metabolism, genomic instability, and autophagy, interact closely with the epigenome. Various postnatal and reversible epigenomic controls of aging, including Yamanaka factors (OKSM and OSK), are now entering a new phase. In the future, the development of aging control using diverse modalities, such as mRNA, artificial peptides, and genome editing, is expected, along with an improved molecular understanding of aging and identification of useful biomarkers.
