The global incidence of dementia has been rising for the past several years, posing significant health challenges regarding its management and prevention. Dementia is associated with a substantial burden on patients and their families. Therefore, effective, evidence-based preventive strategies are required for dementia. To achieve this, the predisposing factors for dementia and their relationship with other diseases need to be determined. Japan has a universal health insurance system and these data have been stored in their respective databases since 2008. Herein we explored the influence of clinical history on the occurrence of dementia based on data collected by the National Health Insurance in Japan and Municipal Care Certification Survey over the past 10 years. Multivariate logistic regression analysis was used to determine the factors from clinical history that affect the risk of dementia development. A significant odds ratio was observed for the development of dementia in 5-year data, involving the clinical history of osteoporosis, depression, internal carotid artery occlusion, schizophrenia, and Parkinson’s disease. In addition, a significant odds ratio was observed for the development of dementia in 10-year data, involving the clinical history of osteoporosis, cataracts, and schizophrenia. Full article

Prospective memory (PM) plays a crucial role in daily autonomy. Metamemory and emotional valence have both been shown to influence PM performance in younger and older adults. However, when considered together, the relationship between emotional valence, metamemory, and PM has not been examined yet, especially whether metamemory PM representations develop with task experience (i.e., before versus after performing a task). We collected data from 25 younger and 19 older adults using an event-based PM task with emotional cues (positive, negative, or neutral). Results revealed that younger adults’ predictions underestimated performance for neutral and negative cues. After performing the task, they showed more accurate representations for neutral cues, indicating that they monitored their representations. Older adults’ predictions overestimated performance for negative PM cues, and they did not modify representations after performing the task. Thus, we do not find evidence that older adults are able to coherently monitor their PM representations. These findings highlight the importance of understanding PM representations, especially in older adults, as they may lead to less strategy use and more impaired PM performance in negative everyday situations.

Aging is a complex process associated with tissue degeneration and an increased risk of age-related diseases. This study aimed to evaluate the impact of Terasen^®, a nutraceutical containing standardized extracts of Euterpe oleracea, Myrciaria dubia, and purified oil of Bixa orellana and Astrocaryum aculeatum on the lifespan of Caenorhabditis elegans. The findings demonstrated that Terasen^® exhibited significant radical scavenging in vitro, decreased the feeding behavior of C. elegans without affecting the animals’ final size, increased the eggs laid in a concentration-dependent fashion, although the total progeny was reduced compared to the control, and increased the median and maximum lifespan. These findings suggest that Terasen^® may improve the lifespan in C. elegans, warranting further investigation. Full article

The current study will explore the post-pandemic bereavement window of widowed caregivers who experienced higher degrees of social isolation and the ways in which leisure was used to cope. A phenomenological multi-case study technique was used to explore the “multiple realities” among female caregivers whose social convoys suffered pre-pandemic because of spousal caregiving and were further impacted by COVID-19 mitigation strategies during the pandemic. Initial analyses utilized the two-cycle approach, as defined by Saldana. In the initial cycle, the researchers independently immersed themselves in the raw data gathered during participant interviews and engaged in open coding to discern concepts, patterns, themes, and categories associated with the multiple realities among the widows whose leisure participation was affected due to the strain of spousal caregiving and exacerbated by COVID-19 mitigation strategies. After completing the first cycle, the researchers then moved to the second phase, thematic analysis, which sought to develop a more structured framework by which to understand the data by identifying, analyzing, and reporting patterns (e.g., themes) within it. A qualitative comparison technique was then employed to deepen our understanding of individuals’ lived experiences. Thematic findings revealed three areas of similarities: Social isolation from caregiving, using leisure to self-focus and explore future possibilities, and core groups. Full article

Background: Whilst qualitative research has previously been conducted on older people’s personal resilience and wellbeing during COVID-19, there are fewer empirical studies on the impact it had on social connectedness for this age group. In this paper we seek to examine older people’s social connectedness to others during the pandemic, their personal experiences of seeking out those connections, and whether there are any identifiable pre-existing factors that enabled them to minimise the impact of enforced isolation. Methods: Using a phenomenological methodology, we conducted in-depth interviews with 13 older people between March and May 2021. These interviews explored the participant’s lived experiences of staying socially connected to others during the enforced lockdowns and various restrictions. Results: Our findings reveal strong themes of personal resilience, sense of coherence and other protective factors, but also highlight the benefits of establishing connections to friends, family, organised groups and community prior to the pandemic. Conclusion: Older people’s ability to stay socially connected is influenced by personal resilience and a positive mindset; pre-existing social ties to others and maintaining a personal sense of coherence and a sense of belonging to people or places. Our findings shed light on the importance of informal social interactions, what it means to feel lonely in older age and indicate that for some the pandemic restrictions may even have offered a welcome space in which to process significant life events.

Although evidence-based programs have been effective for fall prevention in many communities, older adults living in underserved areas cannot access these services due to the shortage of providers and trainers. In this cross-sectional study, a multi-agency approach was adopted for integrating an evidence-based program, A Matter of Balance (AMOB), into the public health curriculum at a rurally placed university. We assessed student learning as well as the community benefits of fall prevention among those who participated in the AMOB program. Eighty-four percent of the students reported intentions of using AMOB training in their future careers. The average of the items for the effectiveness of “Classroom Training” and “Community Training” provided by the students (n = 25) ranged from 3.52 to 4.32 and 3.48 to 4.36, on a Likert scale (1 = Strongly Disagree to 5 = Strongly Agree), respectively. Older adults who participated in the fall prevention community workshops showed increased confidence in reducing falls, protecting themselves from falling, and becoming steadier on their feet after the training (p < 0.05). Our study demonstrates the value of integrating evidence-based programs such as AMOB in a university curriculum to address rural health disparities related to falls. Full article
