RESUMO
Chronic myeloid leukemia (CML) is induced by the expression of the fused tyrosine kinase BCR-ABL, which is caused by a chromosomal translocation. BCR-ABL inhibitors have been used to treat CML; however, the acquisition of resistance by CML cells during treatment is a serious issue. We herein demonstrated that BCR-ABL induced the expression of the RNA helicase DDX5 in K562 cells derived from CML patients in a manner that was dependent on its kinase activity, which resulted in cell proliferation and survival. The knockout of DDX5 decreased the expression of BIRC5 (survivin) and activated caspase 3, leading to apoptosis in K562 cells. Similar results were obtained in cells treated with FL118, an inhibitor of DDX5 and a derivative compound of camptothecin (CPT). Furthermore, FL118 potently induced apoptosis not only in Ba/F3 cells expressing BCR-ABL, but also in those expressing the BCR-ABL T315I mutant, which is resistant to BCR-ABL inhibitors. Collectively, these results revealed that DDX5 is a critical therapeutic target in CML and that FL118 is an effective candidate compound for the treatment of BCR-ABL inhibitor-resistant CML.

ObjectiveãIn 2019, the Ministry of Health, Labour and Welfare emphasized the importance of promoting "Kayoi-no-ba" (or "places to go") initiatives according to the Plan-Do-Check-Action (PDCA) cycle. However, it proposed no specific promotion measures or standardized evaluation frameworks. This study is intended to propose a framework for local government officials to promote and evaluate "Kayoi-no-ba" initiatives according to the PDCA cycle.MethodsãThe working group (WG) conducted a narrative review of research and extracted evaluation models and indicators that could be used to create the framework. The co-researcher review committee discussed a draft framework prepared by the WG, and the WG revised it based on the discussion; this process was repeated four times. Using the completed framework, we calculated the score of the "Kayoi-no-ba" initiatives in 50 Tokyo municipalities and conducted regional correlation analyses on the relationship between the score of the "Kayoi-no-ba" initiatives in 50 Tokyo municipalities and the number of "Kayoi-no-ba" per 1,000 older persons.ResultsãThe completed framework (named "ACT-RECIPE" by rearranging the underlined characters below) comprised the following six evaluation phases: (1) Comprehension: understanding the key lessons around disability and frailty prevention, and the necessity for "Kayoi-no-ba"; (2) Research and Planning: clarifying the current status of "Kayoi-no-ba," the strengths of the community, and the issues to be addressed through a community assessment, and developing a plan to resolve the issues; (3) Team Building and Collaboration: building a team by collaborating with organizations to solve problems; (4) Implementation: implementing the initiatives necessary to solve problems; (5) Evaluation: verifying changes in output and outcome indicators from the initiatives; and (6) Adjustment and Improvement: re-examining plans, teams, content, and goals based on the evaluation results. In these six phases, we designated 10 core items and accompanying subitems. The median score rate of the ACT-RECIPE framework in 50 municipalities was 75% for "Comprehension," 61% for "Research and Planning," 69% for "Team Building and Collaboration," 64% for "Implementation," 31% for "Evaluation," and 56% for "Adjustment and Improvement," and the mean ACT-RECIPE score rate was 57%. A significant positive correlation (rs=0.43, P=0.002) was observed between the ACT-RECIPE mean score rate and the number of "Kayoi-no-ba" per 1,000 older persons.ConclusionãWe proposed the ACT-RECIPE as a framework for promoting and evaluating "Kayoi-no-ba" initiatives according to the PDCA cycle. We hope that this framework will lead to further progress in "Kayoi-no-ba" initiatives and facilitate evaluation of their effectiveness according to the PDCA cycle.

BACKGROUND: This study tested a hypothesised model of the effects of adverse life events on the mental health of middle-aged and older adults living alone, as mediated by thought suppression and help-seeking behaviours, considering gender differences. METHODS: A questionnaire survey was conducted on a sample of 1202 (622 men; 580 women) individuals from 247445 residents aged 50-79 in District A of Tokyo. The questionnaire items covered parameters on adverse life events, help-seeking behaviour, thought suppression, and mental health status. RESULTS: Multiple group structural equation-modelling analysis revealed that the seriousness of adverse life events, help-seeking behaviours, and mental health scores were higher in women than in men. No significant gender differences were observed in thought suppression. The findings support all three proposed hypotheses: severe adverse life events will: (a) give rise to help-seeking behaviours, which will have a positive effect on mental health; (b) intensify thought suppression, which will harm mental health; and (c) inhibit help-seeking behaviour, especially in single middle-aged and older adult men. CONCLUSION: There is a need to develop interventional programs based on the theory of replacement thinking to encourage help-seeking behaviours in middle-aged and older adults.

BACKGROUND: Accumulating social capital in urban areas is essential to improve community health. Previous studies suggested that intergenerational contact may be effective for enhancing social capital. However, no study has examined the effect of intergenerational contact on social capital through a population-based evaluation. This study aimed to investigate the effects of a community-based intervention to increase the frequency of intergenerational contact on social capital among adults aged 25-84 years. METHODS: This study used a non-randomized controlled trial design to conduct a community-based intervention (from March 2016 to March 2019). The study area was Tama ward, Kawasaki city, Kanagawa, Japan. The area comprises five districts; one district was assigned as the intervention group and the other four districts as the control group. We provided the intervention to residents in the intervention group. The intervention comprised three phases: Phase 1 was the preparation term (organizing the project committee); Phase 2 was the implementation term (trained volunteer staff members, conducted the intergenerational greeting campaign, and held intergenerational contact events); and Phase 3 was the transition term (surrendering the lead role of the project to the city hall field workers). In the control group, field workers provided public health services as usual. We conducted mail surveys in September 2016 and November 2018 to assess the effects of the intervention on social capital during Phase 2. Eligible participants were randomly selected from community-dwelling adults aged 25-84 years according to age (10,620 control group individuals and 4479 intervention group individuals). We evaluated social trust, norm of reciprocity, and social support as outcome variables. RESULTS: In total, 2518 participants completed both surveys and were analyzed (control group: 1727; intervention group: 791). We found that social trust (coefficient = 0.065; 95% confidence interval [CI]: 0.006, 0.125) and norm of reciprocity (coefficient = 0.084; 95% CI: 0.020, 0.149) positively changed in the intervention group compared with the control group. CONCLUSIONS: This community-based intervention may contribute to sustaining and improving social capital among community-dwelling adults. TRIAL REGISTRATION: UMIN000046769 (UMIN-CTR); first registered on January 28, 2022 (retrospectively registered).

ObjectivesãA recent long-term care insurance policy encourages the promotion of various types of "Kayoi-no-ba," or places to go, not limited to those focusing on functional training, as resident activities are expected to keep older adults from needing care. In this study, Kayoi-no-ba were voluntary groups in which older adults participated, and their attributes were examined in terms of "diversity of participants" and "autonomy of community residents," based on the type of group.MethodsãThe staff from the preventing long-term care division in each of the 38 municipalities in Tokyo selected 175 voluntary groups that met three criteria: (1) more than three community residents participate in activities at least once a month, (2) participants are primarily older adults or multi-generational residents including older adults, and (3) community residents participate in group management. Representatives from 165 groups responded to the questionnaire. For the group categorization, a latent class analysis was performed using the goals and activities of the group. Participants' age, gender, and health status were used to assess diversity. The number of residents who managed and/or supported group activities and the precise role the residents played in the activities were used to assess autonomy.ResultsãThe groups were categorized into four types: "Physical Exercises," where the primary activity was physical exercise; "Multi-purpose," which included various purposes and activities; "Social Interaction Oriented," where interaction with others was the goal, but physical exercise was not; and "Non-Interaction," where social interaction was not the goal. Participants in the Multi-purpose group ranged in age and were more likely to have health problems, such as mobility limitations, dementia, and frailty, than those in the Physical Exercises and Social Interaction Oriented groups. Moreover, the Multi-purpose group had more resident managers and supporters involved in various roles.ConclusionãThe Multi-purpose group had the most diverse participants and autonomy of residents. However, the type of Kayoi-no-ba should not be considered fixed. The support system should encourage flexible changes such as adding a new activity depending on the situation and the varying needs of the residents.

The urinary antigen test (UAT) is a rapid diagnostic method for pneumococcal pneumonia, but the high false-negative rate of 30% may affect its reliability. To maximize the utility of UAT, it is necessary to investigate the patient factors affecting UAT results. However, there is no report elucidating the association between its utility and pre-existing lung abnormalities. We retrospectively reviewed 388 patients with pneumococcal pneumonia confirmed by blood and/or sputum culture tests. Finally, 94 of 388 patients who had the results of UAT and computed tomography scans were enrolled to evaluate the association between the utility of UAT and patient factors including pulmonary emphysema and fibrosis. The overall positive rate of UAT was 69.1%. The positive rates of UAT in the patients with emphysema were significantly lower than those in individuals without emphysema (33.3% and 77.6%, p < 0.001). Univariate logistic regression analysis showed that the presence of emphysema was associated with a low positive rate (odds ratio 6.944, 95% confidence interval 2.268-21.231). Multivariate logistic analysis showed that the presence of emphysema and lower levels of serum blood urea nitrogen (BUN) were significantly and independently associated with a low positive rate. The combination of emphysema and BUN can potentially stratify the positive rate of UAT in patients with pneumococcal pneumonia. Patients with pneumococcal pneumonia and emphysema have a lower positive rate of UAT. Additionally, the combination of emphysema and serum BUN value may be useful to evaluate the reliability of the negative results of pneumococcal UAT.

BACKGROUND: It is well known that females generally live longer than males, but women tend to suffer from more illnesses and limitations than men do, also for dementia. However, limited empirical evidence is available why this 'male-female health-survival paradox' is observed. This study aimed to investigate factors which account for gender differences in health, particularly cognitive functioning and decline among older adults. METHODS: Data were retrieved from the National Survey of the Japanese Elderly, which is a longitudinal survey of a nationwide representative sample of Japanese adults aged 60 or over. Gender differences in cognitive functioning and decline in three-year follow-ups were decomposed using Blinder-Oaxaca decomposition analysis, regarding demographic, socioeconomic, and health-related factors into the 'explained' component, by differences in individual attributes listed above, and the 'unexplained' component. RESULTS: Empirical analyses showed that women's lower cognitive functioning was partly explained by the endowment effect. Moreover, a shorter duration of formal education and a larger proportion with their longest occupation being domestic worker accounted for steeper cognitive decline and more prevalent mild cognitive impairment in women than in men. CONCLUSION: This empirical study suggested that gender differences in cognitive functioning and decline account for different individual attributes of social determinants among men and women. Particularly, men seem to be more engaged in activities which accumulate intellectual experiences through education and occupation, as suggested by the cognitive reserve hypothesis.

ABSTRACTObjective: Increasing evidence suggests a reverse J-shaped association between body mass index (BMI) and all-cause mortality among the older population. However, findings from non-Western societies including Japan are still sparse. Furthermore, little evidence regarding variation by age and gender in the BMI-mortality relationship in old age exists. This study aimed to examine age and gender variations in the relationship between BMI and all-cause mortality among older Japanese. Design: Data came from a national representative sample of community-dwelling Japanese aged 60 years and older at baseline (n = 4,869). Participants were followed for up to 25 years. We categorized BMI into seven categories: < 18.5, 18.5-19.9, 20.0-21.4, 21.5-22.9, 23.0-24.9, 25.0-26.9, and ≥ 27.0. Cox proportional hazards models were used to assess the relative mortality risk associated with BMI categories. Results: Lower BMI (< 18.5 and 18.5-19.9) was associated with higher mortality, compared to the mid-normal weight category (BMI: 21.5-22.9), after adjusting for covariates. In contrast, high-normal weight (BMI: 23.0-24.9) and overweight (BMI: 25.0-26.9 and ≥ 27.0) were not associated with mortality. Relative to old-old (aged ≥ 75 years), the higher mortality risk associated with lower BMI (< 20) appeared to be more prominent among young-old (aged 60-74 years). A moderately increased mortality risk associated with low BMI (18.5-19.9) was identified among men but not among women. Conclusion: Among older Japanese, low BMI (< 20.0) was associated with higher mortality, while high BMI (≥ 27.0) was not. The increased mortality risk associated with low BMI is more apparent among young-old and men. These age and gender differences need to be considered in assessing healthy body weight in old age.

ObjectivesãMany local governments and elementary and junior high schools in Japan have conducted a "greeting campaign". This has been done in order to activate communication among local residents, and to instill public spirit and sociability in students' minds. However, few studies have explored the significance of greeting campaigns. The present study investigates greeting in neighborhoods and its relationship with students' spontaneous greeting behavior. The study also seeks to understand the quantity of greeting in daily life and its association with a student's community attachment and helping behavior.MethodsãA self-completion questionnaire survey was conducted with 1,346 students studying in the fourth and higher grades at elementary schools, and 1,357 students in the first and second grade at junior high schools. There were 2,692 valid respondents. We performed the following analyses using the data of elementary school students and junior high school students separately. A partial correlation analysis was conducted wherein gender and grade were introduced as control variables. This analysis tested the correlation between the frequency of being greeted by surrounding people and the frequency of greeting by students, of their own accord. A path analysis that tested the relationship between students' greeting behavior, their attachment to residential areas, and helping behavior was also conducted.ResultsãThe results of the partial correlation analysis revealed that there was a positive correlation between the frequency of being greeted by surrounding people and the frequency of greeting by students, of their own accord, regardless of gender and grade. Moreover, the results of the path analysis revealed that the frequency of being greeted was positively associated with community attachment and that the frequency of students' spontaneous greeting behavior was positively associated not only with community attachment but also with helping behavior. The goodness of model fit was high for both the data of elementary school students as well as the data of junior high school students.ConclusionãWe found that exchanging greetings with surrounding people in daily life enhanced students' attachment to the community. In particular, we showed that students' spontaneous greeting behavior led to their helping behavior, which supports the significance of recommending greeting at home, school, or in the local community. Since there was a correlation between the frequency of being greeted and the frequency of greeting willingly, we consider that actions of surrounding adults become important to help students acquire spontaneous greeting behavior.

ABSTRACTBackground:Social isolation and homebound statuses are possible risk factors for increased mortality among older adults. However, no study has addressed the impact of accumulation of these two factors on mortality. The aim of this study was to examine whether such accumulation increased the risk of all-cause mortality. METHODS: The analyzed sample was drawn from a mail survey of 1,023 older adults without instrumental activities of daily living disability. Participants were classified into four groups according to the frequency of both face-to-face and non-face-to-face interactions with others (social isolation and non-social isolation) and the frequency of going outdoors (homebound and non-homebound). Social isolation and homebound statuses were defined as having a social interaction less than once a week and going outdoors either every few days or less, respectively. All-cause mortality information during a six-year follow-up was obtained. RESULTS: In total, 78 (7.6%) participants were both socially isolated and homebound. During the follow-up period, 65 participants died, with an overall mortality rate of 10.6 per 1000 person-years. Cox proportional hazards regression analyses demonstrated that older adults who were socially isolated and homebound showed a significantly higher risk of subsequent all-cause mortality compared with healthy adults who were neither socially isolated nor homebound, independent of potential covariates (aHR, 2.19; 95% CI: 1.04-4.63). CONCLUSION: Our results suggest that the co-existence of social isolation and homebound statuses may synergistically increase risk of mortality. Both active and socially integrated lifestyle in later life might play a major role in maintaining a healthy status.

ObjectivesãThe aim of this research is to classify elderly adults who live alone by their marital status type and to clarify how those types affect their higher-level functional capacity and mental health with a 2-year follow-up survey.MethodsãThis research is based on the results from a survey in 2013. The base-line scores were from 757 participants who completed a survey by mail, carried out in B area of A ward, Tokyo, within the jurisdiction of community general support centers, with people who were not at nursing care levels 4 or 5 and who were not residents of welfare facilities. This study analyzed data for 517 of 527 participants, who answered all questions in the 2015 survey and indicated their marital status. This research categorized the respondents into 4 types of marital status: separation, divorce, bereavement, and unmarried groups. This study adopted the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) as the index of higher-level functional capacity, and the WHO-Five Well-Being Index (WHO-5-J) as the mental health index. In the analysis of the causes of 2-year variations in TMIG-IC total scores and WHO-5-J scores, the dependent variable was each variation. This study used an analysis of covariance in which the fixed factors were types of living alone, sex, annual income, and having children who lived separately in the 2013 survey, and the covariance comprised the base-line scores for the dependent variables, age, and chronic diseases in the 2013 survey.ResultsãWith regards to the variation in TMIG-IC total scores, main effects of the types of living alone were observed. The adjusted variation of covariance decreased most in the separation group (-0.95). For the variation in WHO-5-J scores, main effects of the types of living alone were indicated. In the divorce group, the adjusted variation of covariance was significantly higher than for the unmarried group (2.33 vs. -0.55).ConclusionãThe results revealed that the types of marital status: separated, divorced, bereaved, and unmarried, affect changes in the higher-level functional capacity and mental health status of elderly adults living alone, 2 years later. Thus, although previously regarded as a single category, types of marital status should be considered in the analysis of elderly adults who live alone.

ObjectivesãUsing the Community Child-Rearing Support Scale (CCRSS), which was developed for older adults, we examined 1) the reliability and validity of the scale for multiple generations, as well as the generational differences in the 2) degree and content of supportive behaviors for child rearing and 3) correlates of the behavior, in conjunction with gender differences.MethodsãA mail survey was conducted with residents aged 25-84 years who were randomly selected from two cities in Tokyo and the surrounding areas, and responses were obtained from 8918 residents (response rate: 33%). The respondents were grouped as follows: old-aged (65-84 years), middle-aged (50-64 years), and young-aged (25-49 years). We performed the following analyses by age group and gender: 1) Cronbach's reliability coefficient and a confirmatory factor analysis of the CCRSS, 2) analysis of variance of the total CCRSS scores and scores of the three subscales ("children's security and sound growth," "instrumental support to parents," and "emotional support to parents"), and 3) a multiple regression analysis of the total scores in which various individual characteristics were introduced as explanatory variables.ResultsãThe reliability coefficient was over 0.85 for each age group, and the factor analysis showed good model fitness. Compared to the middle- and young-aged groups, the old-aged group was more likely to provide support for "children's security and sound growth," and equally (for women) or more likely (for men) to provide "emotional support to parents," thereby resulting in the highest total score among the three generations. The mean score of "instrumental support to parents," such as taking care of a child, was the highest for young women, although the score was low overall. Having a child or grandchild under 13 years old and stronger generativity were positively associated with child-rearing support for all age groups; however, the degree of associations varied across the groups. While having a child was strongly associated with support among the young-aged group, the association between support and generativity was stronger for older groups. Moreover, participation in neighborhood associations or volunteer groups and high school or lower education were associated with more support among all age groups, whereas living in rental apartments was associated with less support among the young-aged group.ConclusionãOur findings suggest that the CCRSS can be used for multiple generations and that old people play an important role in child rearing in the community. We found both differences and similarities between generations with respect to the correlates of child-rearing support.

ObjectiveãThe purpose of this study was to examine the relationship between intra- and inter-generational exchange and mental health among young adults aged 25-49 years and older adults aged 65-84 years.MethodsãIn 2016, a community-based, cross-sectional survey was conducted. A total of 3,334 young adults (valid response rate: 24.6%), and 3,116 older adults (valid response rate: 46.0%) completed the survey and were included in the analysis. Their mental health was evaluated using the World Health Organization-Five Well-Being Index (WHO-5), and those who scored under 13 or scored less than one on any item were considered to have poor mental health. To evaluate the intra- or inter-generational exchange, participants were asked about their frequency of interaction with people aged 20-49 years or aged ≥70, excluding family and co-workers. Young adults who interacted with people aged 20-49 years or older adults who interacted with people ≥70 were classified as "having intra-generational exchange," while young adults who interacted with people ≥70 years or older adults who interacted with people aged 20-49 years were classified as "having intergenerational exchange." Therefore, individuals who interacted with both generations were classified as "having multi-generational exchange," and those who did not interact with any generation were categorized as "no exchange." We conducted a logistic regression analysis that included mental health as a dependent variable, intra- and inter-generational exchange as independent variables, and gender, age, educational attainment, marital status, living situation, subjective economic status, social participation, employment, self-rated health, and Instrumental Activity of Daily Living as covariates.ResultsãOf the 3,334 young adults, 61.5% were mentally healthy, 51.3% had intra-generational exchange, 21.9% had inter-generational exchange, 16.5% had multi-generational exchange, and 42.7% did not have any exchange. Of the 3,116 older adults, 65.8% were mentally healthy, 67.9% had intra-generational exchange, 34.3% had inter-generational exchange, 29.9% had multi-generational exchange, and 21.1% did not have any exchange. A logistic regression analysis revealed that "having intra-generational exchange" and "having intergenerational exchange" were significantly related to better mental health in both young adults (intra-generational; Odds ratios (OR) 1.19, 95% confidence intervals (CI) 1.10-1.30: inter-generational; OR 1.13, 95% CI 1.03-1.25) and older adults (intra-generational; OR 1.15, 95% CI 1.02-1.29: inter-generational; OR 1.46, 95% CI 1.30-1.65). Therefore, "having multi-generational exchange" was more strongly related to better mental health compared with "only having intra-generational exchange."ConclusionãAmong young and older adults, intra- and inter-generational exchange were related to better mental health, and multi-generational exchange showed the strongest relationship with better mental health.

OBJECTIVES: Isolation and anxiety among child-rearing mothers in Japan are a current social problem. Involving diverse people in the community is recognized as an important factor in successful child rearing. This study aimed to develop a scale to measure supportive behavior for child rearing among older adults in the community and examine its reliability and validity. METHODS: Items were selected to measure supportive behaviors for child rearing in the community in accordance with constructs introduced via literature reviews and a preliminary investigation. Participants were asked to evaluate the frequency of each behavior on a four-point scale in a mail-based survey. Of a random sample of 1,500 individuals aged 60-69, living in the Tokyo metropolitan area, 813 (54%) responded. Construct validity and reliability of the scale were examined by a confirmatory factor analysis and Cronbach's reliability coefficient. The validity was also examined by clarifying whether the assumed positive associations between the scale and the following variables were observed: frequency of contact with community residents; the generativity scale, which measured concern for the next generation; and experience of child rearing measured by number of own children and level of support for grandchildren. Pearson's correlation and multiple regression analyses were performed for the analysis of the results. RESULTS: The literature review and preliminary investigation revealed three constructs of supportive behaviors: "children's security and sound growth," "instrumental support to parents," and "emotional support to parents." A second-order factor analysis that modeled "child-rearing support in the community" as a higher-order factor above these three factors showed a good model fit when one item was deleted. The reliability coefficient was high enough (alpha=0.87) with the remaining seven items. As expected, the total score positively and significantly correlated with the frequency of contact with residents, especially with the younger generation, including children and their parents; generativity score; number of children; and care for grandchildren. Multiple regression analyses revealed that the measured child-rearing support in the community was largely explained by the frequency of contact with the younger generation. However, being female, taking care of grandchildren, and a higher generativity correlated with a higher child-rearing support score even after controlling for the frequency of contact. CONCLUSION: Reliability and validity of the community child-rearing support scale, consisting of seven items, were confirmed. Further studies are required to show applicability of the scale to diverse communities and age groups, and investigate the effects of the measured supportive behaviors on the child-rearing generation.

Few studies have focused on the relationship between the trajectories of long-term changes in body mass index (BMI; weight (kg)/height (m)(2)) and all-cause mortality in old age, particularly in non-Western populations. We evaluated this association by applying group-based mixture models to data derived from the National Survey of the Japanese Elderly, which included 4,869 adults aged 60 or more years, with up to 7 repeated observations between 1987 and 2006. Four distinct BMI trajectories were identified: "low-normal weight, decreasing" (baseline BMI = 18.7; 23.8% of sample); "mid-normal weight, decreasing" (baseline BMI = 21.9; 44.6% of sample); "high-normal weight, decreasing" (baseline BMI = 24.8; 26.5% of sample); and "overweight, stable" (baseline BMI = 28.7; 5.2% of sample). Survival analysis with an average follow-up of 13.8 years showed that trajectories of higher BMI were associated with lower mortality. In particular, relative to those with a mid-normal weight, decreasing BMI trajectory, those with an overweight, stable BMI trajectory had the lowest mortality, and those with a low-normal, decreasing BMI trajectory had the highest mortality. In sharp contrast with prior observations from Western populations, BMI changes lie primarily within the normal-weight range, and virtually no older Japanese are obese. The association between BMI trajectories and mortality varies according to the distribution of BMI within the population.

OBJECTIVES: This study examined the possibility and necessity for expansion and diffusion of a new employment support facility for older job seekers in metropolitan areas based on health and welfare measures. This longitudinal study assessed questionnaire responses from older job seekers at a new facility established in Ota ward in the Tokyo metropolitan area as a compliment to the conventional system comprised of Hello Work and the Silver Human Resources Center. METHODS: We offered questionnaires to job seekers at their first facility visit and asked them to return them by mail (baseline survey). Follow-up surveys of the same respondents were conducted after 2, 4, 8, and 12 weeks, with questions about demographics, personal status, social activities, mental health, and job search status. The surveys were administered from January 2013 to March 2014. RESULTS: We obtained 128 responses (average respondent age: 63.8 years) from 180 baseline survey questionnaires. The respondents included 82 males and 46 females. The response rates were over 90% for all follow-up surveys. Among respondents, 71.4% had less than a senior high school level of education. The average annual household income was less than 3 million yen and less than 1 million yen for 68.0% and 16.0% of the participants, respectively. The life circumstances were "hard" or "very hard" for 56.3% of respondents. Among respondents, 78.9% indicated that they were seeking employment for economic reasons. Women and those over 65 years of age were more likely to search for jobs for their well-being than men and respondents less than 65 years of age. The majority of respondents indicated that they wanted to make use of their abilities or experience and many hoped to work as garbage collectors, cooks, or apartment caretakers. CONCLUSION: We found that the main objective of older job seekers living at this facility was economic acquisition. Men and those less than 65 years of age were at particular risk for economic distress, poor mental health, and were more likely to be searching for regular employment. A relatively higher proportion of women and respondents over 65 years of age were seeking jobs for their well-being; a need for social relationships that may be more pronounced among women in this study population.

OBJECTIVES: Here we investigated the characteristics of users of an emergency system that tracks elderly people, known as the "elderly monitoring key ring." The relevance of a spreading policy or strategy and the user characteristics were investigated to develop programs conducted by local governments to manage unidentified elderly people with dementia. METHODS: A questionnaire was conducted in July 2013 in a district of the Ota Ward in Tokyo. The questionnaire was administered to residents >65 years of age (N=7,608), of which 5,166 (67.9%) responded. Fully completed responses (N=4,475) were analyzed with binomial logistic regression analysis using "monitoring key rings" as the dependent variable and simultaneously inputted sex, age, living arrangement, social isolation, Instrumental Activities of Daily Living (IADL), and complaints of memory loss as independent variables. Interviews were also conducted in August 2014 of the staff members (N=12) of six community comprehensive support centers in the Ota Ward. RESULTS: The logistic regression analysis results indicated that women used the monitoring key rings 1.64 times more often than men, late elderly used it 4.39 times more often than early elderly, elderly living alone used it 2.14 times more often than elderly not living alone, non-isolated people used it 1.36 times more often than isolated people, IADL non-independent people used it 1.50 times more often than independent people, and people with complaints of memory loss used it 1.37 times more often than those without such complaints. On the other hand, the results of interviews indicated that elderly people living alone, those with worries, and relatively young and healthy elderly people were targets. The main targets of community comprehensive support centers were elderly individuals living alone and early elderly individuals. The utilization rate of elderly people living alone was high; however, that of early elderly people was low. They recognized that people registered with the system tended to have high anxiety, be relatively young and highly independent, and register after learning about the system from their peers or through neighborhood associations. CONCLUSION: Individuals who were female, late elderly, elderly living alone, non-isolated, IADL non-independent, or had complaints of memory loss were most likely to be registered with the key ring. The circumstance of registration which community comprehensive support centers recognize related to the low utilization rate of elderly people who are isolated. In the future, the system should be introduced to socially isolated as well as relatively young elderly people.

Generational labels (e.g., Millennials and Baby Boomers) are widely used in daily life to represent the unique characteristics of groups of people. However, the existence of generational differences remains contentious. In their focal paper, Costanza et al. (2023) critically reviewed the literature on generational differences and proposed two future research directions: the social constructionist and lifespan development perspectives. In this commentary, we aimed to extend the proposed directions for future research on generational differences by integrating the two perspectives into one theoretical framework. Future research should investigate how proximal social relationships (e.g., intergenerational relations) and distal social norms (e.g., age norms) change over historical time and whether these historical changes shape individuals' development and aging. The theoretical framework that integrates the two proposed research directions may stimulate research on generational differences to progress beyond the concept of generations.

BACKGROUND: Universal health coverage means that all people can access essential health services without incurring financial hardship. Even in countries with good service coverage and financial protection, the progress towards universal health coverage may decelerate or be limited with respect to the growing older population. This study investigates the incidence/prevalence, determinants, and consequences of catastrophic health expenditure (CHE) and unmet need for healthcare and assesses the potential heterogeneity between younger (≤ 64 years) and older people (65 years≤). METHODS: Utilising an annual nationally representative survey of Japanese aged 20 years and over, we estimated the incidence of CHE and unmet need for healthcare using disaggregated estimates by household members' age (i.e. ≤64 years vs. 65 years≤) between 2004 and 2020. Using a fixed-effects model, we assessed the determinants of CHE and unmet need along with the consequences of CHE. We also assessed the heterogeneity by age. RESULTS: Households with older members were more likely to have their healthcare needs met but experienced CHE more so than households without older members. The financial consequences of CHE were heterogeneous by age, suggesting that households with older members responded to CHE by reducing food and social expenditures more so than households without older members reducing expenditure on education. Households without older members experienced an income decline in the year following the occurrence of CHE, while this was not found among households with older members. A U-shaped relationship was observed between age and the probability of experiencing unmet healthcare need. CONCLUSIONS: Households with older members are more likely to experience CHE with different financial consequences compared to those with younger members. Unmet need for healthcare is more common among younger and older members than among their middle-aged counterparts. Different types and levels of health and financial support need to be incorporated into national health systems and social protection policies to meet the unique needs of individuals and households.
