Abstract
OBJECTIVES To investigate the trajectories of social networks and interactions among older Japanese individuals during the COVID-19 pandemic. STUDY DESIGN We used data from a cohort of community-dwelling older individuals from the Otassha study's 2019-2022 survey. Participants comprised 606 older individuals who participated in the 2019 survey and were followed up at least once. MAIN OUTCOME MEASURES Social networks were assessed using the Lubben Social Network Scale-6 (LSNS-6), whereas social interactions were assessed by the frequency of face-to-face or non-face-to-face contact with non-resident family members and friends. Trajectories of the LSNS-6 and face-to-face and non-face-to-face interactions were identified using group-based semiparametric mixture modeling. The trajectories of change in the LSNS-6 from 2019 were also identified. The factors associated with the changes in trajectory patterns were examined using logistic regression analysis. RESULTS Three LSNS-6 trajectories were identified, with slightly decreasing patterns over time. Specifically, face-to-face interactions tended to decrease over time, whereas non-face-to-face interactions exhibited almost no change. The reduction in LSNS-6 in the decreased pattern failed to recover to its pre-pandemic level. The group of participants with the decreased pattern had a significantly higher proportion of people participating in group activities [odds ratio (95 % confidence interval): 2.27 (1.12-4.59)] and performing calisthenics twice a week than the group with the maintained pattern [2.08 (1.18-3.68)]. CONCLUSIONS During the three years of the pandemic, no changes were observed in the social networks of community-dwelling older Japanese individuals.

Abstract
Objective In 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.Methods The 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.Results The 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.Conclusion We 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.

Abstract
Objective In this study, we clarified the characteristics of tasks performed by older assistant care workers at geriatric health services facilities, by individual characteristics and work status. Additionally, we examined the relationship between the tasks and benefits of working for older assistant care workers.Methods A self-administered questionnaire survey was provided to 2,571 elderly care facilities employing assistant care workers aged ≥60. A total of 1,606 responses were obtained, and personal characteristics, working conditions, tasks, and benefits of working for older care assistants were surveyed. Thirteen work tasks were established and categorized into four broad categories; user transfer assistance, facility maintenance, meal-related assistance, and managing and talking to users. Seven benefits of working as care assistants were "contribution to society," "social connection," "purpose of life," "income," "learning from caregiving," "health maintenance and promotion," and "time utilization."Results Most of the respondents were women and relatively young workers. Among tasks, men, younger workers, and those working >5 days weekly represented a high proportion of those performing user transfer assistance tasks. Tasks on managing and talking to users were not correlated with sex, age, and number of days worked, but those with more flexible work patterns were more likely to be engaged in such tasks. Logistic regression analysis showed that user transfer assistance was correlated with benefits of working, such as "contribution to society," "social connection," and "learning from caregiving." Moreover, facility maintenance was associated with "income," "health maintenance and promotion," and "time utilization" and meal-related assistance was associated with "learning from caregiving." Managing and talking to users was associated with "contribution of society," "social connection," "purpose of life," and "learning from caregiving."Conclusion The tasks of the workers were associated with individual characteristics and work status. The perception of benefits between the working tasks that involved frequent contact with users and those that did not were considerably different.

Abstract
INTRODUCTION We examined the efficacy of a multidomain intervention in preventing cognitive decline among Japanese older adults with mild cognitive impairment (MCI). METHODS Participants aged 65-85 years with MCI were randomized into intervention (management of vascular risk factors, exercise, nutritional counseling, and cognitive training) and control groups. The primary outcome was changes in the cognitive composite score over a period of 18 months. RESULTS Of 531 participants, 406 completed the trial. The between-group difference in composite score changes was 0.047 (95% CI: -0.029 to 0.124). Secondary analyses indicated positive impacts of interventions on several secondary health outcomes. The interventions appeared to be particularly effective for individuals with high attendance during exercise sessions and those with the apolipoprotein E ε4 allele and elevated plasma glial fibrillary acidic protein levels. DISCUSSION The multidomain intervention showed no efficacy in preventing cognitive decline. Further research on more efficient strategies and suitable target populations is required. HIGHLIGHTS This trial evaluated the efficacy of multidomain intervention in individuals with MCI. The trial did not show a significant difference in preplanned cognitive outcomes. Interventions had positive effects on a wide range of secondary health outcomes. Those with adequate adherence or high risk of dementia benefited from interventions.

Abstract
Smartphone applications aimed at enhancing physical, cognitive, and social activities through mobile health (mHealth) technology are of increasing interest. Their feasibility and acceptability, alongside impacts on frailty phenotype scores and step counts among older adults with frailty, remain to be fully validated. This study presents a 13-week preliminary intervention trial assessing an mHealth app's feasibility in a cohort of 34 eligible older adults, including 5 frail and 29 pre-frail participants. The intervention entailed a 6-week course on app usage, followed by 7 weeks of observation, with four participants withdrawing early. Feasibility was determined by login and active use rates, with a target login rate of 60% or higher. Post-intervention, 100% session attendance and a median login rate of 88.4% were observed. Acceptability was high, with 73% affirming the app's health benefits. Notably, frailty scores and step counts improved post-intervention, underscoring the app's potential for supporting older adults with frailty.

Abstract
Objective Esophageal cancer is a gastrointestinal cancer with a poor prognosis. However, it is curable and can be treated endoscopically if it is detected at an early stage. The objective of this study was to identify the factors that contribute to early detection. Methods From April 2011 to December 2019, we retrospectively investigated consecutive patients diagnosed with esophageal squamous cell carcinoma (ESCC) through upper gastrointestinal endoscopy at two hospitals of Kawasaki Medical University based on medical records. The factors contributing to the early detection of ESCC were investigated by comparing patients with ESCC with those undergoing health checkups in whom no organic lesions were found in the upper gastrointestinal tract on endoscopy (controls). Patients Factors contributing to early detection were examined in 402 ESCC cases and 391 sex- and age-matched controls, and early and advanced cancers were compared along with the risk factors for ESCC. Results A multivariate analysis showed that alcohol consumption and smoking, concomitant cancer of other organs, and a low body mass index (BMI) were factors associated with ESCC (odds ratio [OR], 4.65; 95% confidence interval [CI], 2.880-7.520, OR,3.63; 95% CI, 2.380-5.540, OR, 2.09; 95% CI, 1.330-3.270, OR, 6.38; 95% CI, 3.780-10.800), whereas dyslipidemia was significantly less common in patients with ESCC (OR, 0.545; 95% CI, 0.348-0.853). Comparing early and advanced cancers, a history of endoscopic screening was the only factor involved in early detection (OR, 7.93; 95% CI, 4.480-14.00). Conclusion The factors associated with ESCC include alcohol consumption, smoking, concomitant cancer of other organs, and a low BMI. Endoscopy in subjects with these factors may therefore be recommended for the early detection of ESCC.

Abstract
BACKGROUND Comprehensive genome profiling (CGP) serves as a guide for suitable genomically matched therapies for patients with cancer. However, little is known about the impact of the timing and types of cancer on the therapeutic benefit of CGP. MATERIALS AND METHODS A single hospital-based pan-cancer prospective study (TOP-GEAR; UMIN000011141) was conducted to examine the benefit of CGP with respect to the timing and types of cancer. Patients with advanced solid tumors (>30 types) who either progressed with or without standard treatments were genotyped using a single CGP test. The subjects were followed up for a median duration of 590 days to examine therapeutic response, using progression-free survival (PFS), PFS ratio, and factors associated with therapeutic response. RESULTS Among the 507 patients, 62 (12.2%) received matched therapies with an overall response rate (ORR) of 32.3%. The PFS ratios (≥1.3) were observed in 46.3% (19/41) of the evaluated patients. The proportion of subjects receiving such therapies in the rare cancer cohort was lower than that in the non-rare cancer cohort (9.6% and 17.4%, respectively; P = 0.010). However, ORR of the rare cancer patients was higher than that in the non-rare cancer cohort (43.8% and 20.0%, respectively; P = 0.046). Moreover, ORR of matched therapies in the first or second line after receiving the CGP test was higher than that in the third or later lines (62.5% and 21.7%, respectively; P = 0.003). Rare cancer and early-line treatment were significantly and independently associated with ORR of matched therapies in multivariable analysis (P = 0.017 and 0.004, respectively). CONCLUSION Patients with rare cancer preferentially benefited from tumor mutation profiling by increasing the chances of therapeutic response to matched therapies. Early-line treatments after profiling increase the therapeutic benefit, irrespective of tumor types.

Abstract
AIM This study aimed to examine the relationships between levels of competence and impaired physical and cognitive functions in older adults. METHODS We used a data set of the Integrated Longitudinal Studies on Aging in Japan for 2017 including 5475 community-dwelling older adults. Levels of competence were assessed using the Japan Science and Technology Agency Index of Competence (JST-IC). Grip strength (low grip strength: <28 kg for men and <18 kg for women) and gait speed (slow gait speed: <1.0 m/s for both sexes) were evaluated as physical function measurements, and the Mini-Mental State Examination (cognitive decline: <24 on the Mini-Mental State Examination) was used to assess cognitive function. RESULTS The JST-IC had areas under the curve estimated from receiver operating characteristic analysis ranging from 0.65 to 0.73 for detecting low function as assessed by these tests. Restricted cubic spline curves showed that the shape of the association between the JST-IC and impaired function depended on sex and the test used. The comparison between perfect and imperfect JST-IC scores showed significant differences in the prevalence of low grip strength in both sexes, slow gait speed in women, and cognitive decline in men. CONCLUSIONS It may be insufficient to identify those with impaired physical or cognitive function using the JST-IC. The shape of the association with the JST-IC varies across their measurements. Our findings can help interpret JST-IC scores in the context of low physical and cognitive functions. Geriatr Gerontol Int 2024; 24: 352-358.

Abstract
Objectives To support care workers, some care facilities employ older individuals as care assistants for peripheral, non-professional tasks. However, the size of the facilities influences their employment needs and support systems for older care workers. Therefore, this study examined the rationale for employing older assistant care workers; the challenges they face; educational systems; and the efforts to facilitate continued employment based on facility size.Methods Initially, a fax survey was conducted with 3,591 facilities associated with the National Association of Geriatric Health Services Facilities to determine the proportion of older assistant care workers employed. Thereafter, a questionnaire survey was administered to gather more information. Out of 3,591 facilities, 2,170 responded to the survey, and 1,261 responded to the questionnaire. In this study, care assistants aged ≥60 years were classified as older care assistants. The facilities were categorized based on admission capacity into two groups: "small/medium facilities" (≤99 residents) and "large facilities" (≥100 residents). A chi-square test was conducted for data analysis.Results Of the all geriatric health services facilities, 31.7% employed older assistant care workers. Moreover, the questionnaire survey responses showed they are employed by 687 facilities. Further analysis revealed that larger facilities employed a higher number of older care assistants than small/medium facilities. Small/medium facilities tended to have fewer training systems for older care assistants than larger facilities (30.0% for small/medium facilities vs. 21.6% for large facilities; P=0.014). Furthermore, the work of older care assistants in small/medium facilities was more susceptible to family circumstances than those in larger facilities (15.7% for small/medium facilities vs. 10.2% for large facilities; P=0.033). Compared to small/medium facilities, larger facilities were more likely to state that their employment objective was to reduce the risk of care accidents (19.8% for small/medium facilities vs. 26.3% for large facilities; P=0.046) and provide psychological support, such as periodic interviews, to older care workers to ensure continued employment (24.1% for small/medium facilities vs. for large facilities 37.3%; P<0.001).Conclusion Larger facilities employeda higher number of older care assistants than small/medium facilities. Furthermore, small/medium facilities were less likely to provide psychological support and had a less structured training system, compared to larger facilities. Additionally, the work of older care assistants in small/medium facilities was more susceptible to family circumstances and other factors, which could affect their work performance. Thus, developing adequate support systems in small/medium facilities is crucial to promoting the employment of older care assistants.

Abstract
Introduction Social isolation has been recognized as a contributing factor to negative health outcomes. Although living alone is associated with health-related outcomes, existing findings are inconsistent. It is not the act of living alone that may predict poor health, but rather social isolation that can lead to increased mortality risk. This study investigated the combined associations of social isolation and living alone with mortality among community-dwelling older adults. Methods We included older adults from Itabashi ward, Tokyo, who participated in comprehensive health checkups. Participants were categorized into four groups based on their social isolation status and living alone. The primary outcome was all-cause mortality, analyzed using Cox proportional hazards models. Results Of the 1,106 participants (mean age 73, 42% male), 4.5% experienced both social isolation and living alone. This combination was associated with a worse prognosis regarding all-cause mortality (hazard ratio (HR): 2.08 [95% confidence interval (CI), 1.08-4. 00]). Those who were socially isolated but not living alone also showed a trend towards higher mortality risk (HR: 1.41 [95% CI, 0.90-2.20]). Contrastingly, those who were not socially isolated and lived alone did not show an increased mortality risk (HR: 0.81 [95% CI, 0.44-1.49]). Discussion and conclusion Living alone is not inherently associated with a poor prognosis in older adults; however, social isolation was associated with a higher mortality risk. Healthcare providers should focus on enhancing social interactions and support for older adults because of their effects on health rather than solely addressing living arrangements to prevent adverse health events.

Abstract
AIM This study examined the effects of fear of COVID-19 on older volunteers' willingness to continue activities that required face-to-face interactions. METHODS From September to November 2020, a self-administered questionnaire survey was conducted with 481 older adult volunteers. A total of 423 responses were collected; 343 had no missing items and were included in the analysis. Analysis items included willingness to continue volunteer activities, fear of COVID-19, mental and physical health, and a group of items related to factors influencing the continuation of volunteer activities. RESULTS The structural analysis of covariance indicated that volunteer orientation, which included items considered to be factors for continuing volunteer activities, had a significant positive influence on the willingness to continue activities. Fear of COVID-19 had a significant negative effect on the latent variable mental and physical health, which consisted of a subjective sense of health, but fear of COVID-19 and physical and mental health had no significant effect on the willingness to continue volunteering. CONCLUSIONS Our results suggest that the willingness of older adults to continue volunteer activities during the COVID-19 pandemic is influenced by their volunteer orientation and is not affected by their fear of COVID-19.

Abstract
AIM Muscle mass and strength correlate with cognitive function; however, it remains unclear whether dynapenia (i.e., muscle weakness with preserved muscle mass) is relevant. This study aimed to explore whether dynapenia is associated with global cognitive function in community-dwelling older Japanese adults. METHODS This cross-sectional study used data from the Integrated Research Initiative for Living Well with Dementia Cohort Study, which pooled data from five community-based geriatric cohorts. Dynapenia was defined as muscle weakness without muscle mass loss according to the Asian Working Group for Sarcopenia criteria. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). An ordered logistic regression analysis was conducted with dynapenia as the exposure and with cognitive decline stages, defined as an MMSE score of 27-30 for normal cognition, 24-26 for possible cognitive decline, and <24 for cognitive decline, as the outcome, stratified by sex and adjusted for age, muscle mass, education, alcohol consumption, smoking habits, living alone, and non-communicable diseases. RESULTS We analyzed data for 3338 participants (2162 female) with preserved muscle mass. Of these, 449 (13.5%) had dynapenia, and 79 (2.4%) exhibited cognitive decline. Multivariate odds ratios (95% confidence interval) for cognitive decline among those with dynapenia, compared with those without dynapenia, were 1.51 (1.02-2.24) for males and 2.08 (1.51-2.86) for females. CONCLUSIONS Muscle weakness is associated with cognitive decline, even in individuals with preserved muscle mass. Further studies are needed to better understand the association between muscle weakness and cognitive decline over time in order to develop dementia prevention strategies for those with dynapenia.

Abstract
Objectives The mental health condition of care staff in Japan is becoming problematic. Older assistant workers are currently being employed to assist care staff with their jobs and alleviate their job burden. This employment of older assistant workers is drawing attention; however, their influence on the job facilitating and inhibiting factors of care staff and the association with the care staff's emotional exhaustion remains unclear. In this study, we aim to examine how the employment of older care assistant workers relates to the job-facilitating and job-inhibiting factors of care staff and explore that association with the care staff's emotional exhaustion.Methods Data from a mail survey of geriatric health services facilities with older assistant workers were analyzed. Among the answers obtained from the care staff, answers from 5,185 who reported working in facilities that employ older assistant workers (over the age of 60) were analyzed. The Emotional Exhaustion subscale of the Japanese Version of the Burnout Questionnaire was used as the dependent variable. The change in job-facilitating and job-inhibiting factors of care staff due to the employment of older assistant workers (improve, maintain/exacerbate) was explored for nine contents.Results Care staff reported a decrease in the total volume of the task (63.6%), less stress during daily tasks (39.8%), and more concentration on the tasks that require expert care knowledge (38.0%). The results of multiple regression analysis showed that the emotional exhaustion score of care staff was low when the total volume of tasks decreased (β=-0.383, 95%CI=-0.719, -0.047), when less stress was perceived during daily tasks (β=-0.432, 95%CI=-0.796, -0.068), when concentration on tasks that required expert care knowledge increased (β=-0.574, 95%CI=-0.937, -0.210), and when human relationships among staff improved (β=-0.871, 95%CI=-1.263, -0.480). Conversely, an increase in tasks requiring work with regional personnel and organizations (β=0.800, 95%CI=0.162, 1.437) was associated with a high emotional exhaustion score.Conclusion The employment of older care workers was related to the job-facilitating or job-inhibiting factors of care staff, and the change in these factors was associated with lower emotional exhaustion. The employment of older personnel may lower the risk of burnout among care staff.

Abstract
BACKGROUND Whether age-related decline in the musculoskeletal system may contribute to a decline in cognitive performance or vice versa is unclear. Understanding the direction of their associations and the extent to which upper and lower extremities similarly predict subtle changes in high-level cognitive performance will help elucidate their mechanisms, especially that of the hand dexterity. METHODS We evaluated the bidirectional associations of motor performance and high-level cognitive domains in 165 highly cognitively and physically healthy older adults. Motor performance tests consisted of handgrip strength, hand dexterity, assessed with the Purdue Pegboard Test (PPT), and usual and maximum gait speeds. High-level cognitive measures included executive function and information processing speed. The Trail Making Test (TMT)B and the letter and category fluency tests (LFT and CFT) evaluated executive function, while the TMTA and Digit Symbol assessed processing speed. Measurements were taken at baseline and at 2-, 5- and 7-year follow-up. RESULTS Generalized linear mixed-effect models showed that baseline hand dexterity and its trajectory predicted changes in TMTB, CFT, TMTA, and Digit Symbol over time, and vice versa. Baseline maximum gait speed was associated with LFT over time and vice versa. No associations were found for handgrip and usual gait speed. CONCLUSION The positive bidirectional association observed both in hand dexterity and maximum gait speed with executive function performance and that of hand dexterity with processing speed over time highlights a reciprocal relationship where each factor affects the other and both factors are dependent on each other, suggesting commonality in their neural basis.

Abstract
INTRODUCTION Frailty is a crucial health issue among older adults. Growth differentiation factor 15 (GDF15) is associated with inflammation, oxidative stress, insulin resistance, and mitochondrial dysfunction, which are possible pathogeneses of frailty. However, few longitudinal studies have investigated the association between GDF15 and the incidence of frailty. Therefore, we investigated whether high serum GDF15 levels are associated with the incidence of frailty. METHODS A total of 175 older adults (mean age : 77 ± 6 years; 63% women) with cardiometabolic diseases and no frailty out of the two criteria at baseline participated. Individuals with severe renal impairment or severe cognitive impairment were excluded. Serum GDF15 levels were measured at baseline. Patients were asked to assess frailty status at baseline and annually during follow-up using the modified version of the Cardiovascular Health Study (mCHS) and the Kihon Checklist (KCL). We examined the association between GDF15 tertiles and each frailty measure during follow-up (median 38-39 months). In the multivariate Cox regression analysis, with the GDF15 tertile groups as the explanatory variables, hazard ratios (HRs) and 95% confidence intervals (CIs) for incident frailty were calculated after adjusting for covariates and using the lowest tertile group as the reference. RESULTS During the follow-up period, 25.6% and 34.0% of patients developed frailty, as defined by the mCHS and KCL, respectively. The highest GDF15 tertile group had a significantly higher incidence of mCHS- or KCL-defined frailty than the lowest GDF15 tertile group. Multivariate Cox regression analysis revealed that the adjusted HRs for incident mCHS- and KCL-defined frailty in the highest GDF15 tertile group were 3.9 (95% CI: 1.3-12.0) and 2.7 (95% CI: 1.1-6.9), respectively. CONCLUSION High serum GDF15 levels predicted the incidence of frailty among older adults with cardiometabolic diseases and could be an effective marker of the risk for frailty in interventions aimed at preventing frailty, such as exercise and nutrition.

Abstract
This study examined the ability of a computer-based cognitive assessment tool (CompBased-CAT) to predict mild cognitive impairment (MCI) in community-dwelling older adults. A two-year longitudinal study was conducted using data from 2016 to 2018 from the Otassha study cohort of community-dwelling older adults. MCI was defined as a Mini-Mental Status Examination (MMSE) score of <27. The CompBased-CAT was used at baseline, with each subtest score converted into a Z-score. Subsequently, the total Z-scores were calculated. Participants were divided into robust and MCI groups, and all variables were compared using the t-test or χ2 test. Receiver operating characteristic (ROC) curves and logistic regression analyses were conducted, with MCI and total Z-scores as dependent and independent variables, respectively. Among the 455 participants (median age, 72 years; range, 65-89 years; 282 women and 173 men), 32 developed MCI after two years. The participants in the MCI group were significantly older. They had lower maximal gait speed, baseline MMSE scores, subtest Z-scores, and total Z-scores than those in the robust group. The area under the ROC curve was 0.79 (95% confidence interval: 0.70-0.87; P <0.01). The sensitivity was 0.76, and the specificity was 0.75. The logistic regression analysis showed an odds ratio of 1.34 (95% confidence interval: 1.18-1.52; P <0.01). This study showed that CompBased-CAT can detect MCI, which is an early stage of dementia. Thus, CompBased-CAT can be used in future community health checkups and events for older adults.

Abstract
PURPOSE Although examining the dose-response curves of physical activity (PA) and sitting time with health-related outcomes is an important research agenda, the results for older Japanese adults are extremely limited. We examined the dose-response associations of PA and sitting time with all-cause mortality among older Japanese. METHODS Initially, 8,069 non-disabled residents (4,073 men; 3,996 women) aged 65-84 years of Ota City, Japan, were analyzed. Moderate-to-vigorous PA (MVPA) and sitting time were evaluated using the International Physical Activity Questionnaire-Short Form. Multivariate-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of MVPA and sitting time for all-cause mortality were calculated, and the dose-response curves were examined using restricted cubic splines (RCS). RESULTS During 4.1 years of follow-up, 458 participants (5.7%; 331 men and 127 women) died. Compared with the low MVPA (<600 metabolic equivalents [METs]·minutes/week) group, HR for mortality gradually reduced in moderate (600-3,000 METs·minutes/week) and high (>3,000 METs·minutes/week) MVPA groups (moderate: HR 0.66; 95% CI, 0.54-0.82; high: HR 0.58; 95% CI, 0.45-0.75; P < 0.001 for trend). RCS showed that the HR for mortality reduced linearly up to approximately 2,000 METs·minutes/week of MVPA, and maximal risk reduction was seen at approximately 3,000-4,500 METs·minutes/week of MVPA. No significant dose-response association of sitting time with mortality was observed. CONCLUSION Higher MVPA levels reduced all-cause mortality risk, in a significant inverse non-linear dose-response manner. Sitting time was not significantly associated with all-cause mortality. It is important to disseminate the significance of even a slight increase in the MVPA for reducing mortality risk.

Abstract
Social isolation among older adults affects their physical and mental health. Ego-resilience is associated with flexible adaptation to various environments and acceptable behaviors. However, its association with social isolation among older people is unclear. Therefore, a health survey was conducted with 510 adults aged 65 years or older to assess social isolation, its associated factors, and ego resilience. The results showed that the social isolation group had a lower median ego-resiliency scale score (42.0) compared to the non-social isolation group (38.0). The social isolation group were mostly males without spouses, took time to move, had more depressive moods, and poorer subjective health status. The non-social isolated group had faster maximum walking speed. Low ego-resilience was newly identified as a factor associated with social isolation among older people, as were being male, having no spouse, and depressive symptoms. Mediation analysis revealed that ego-resilience affected social isolation and was partially mediated by depressive symptoms.

Abstract
An 82-year-old, male. He visited his local doctor with a chief complaint of dyspnea on exertion. Anemia was noted, and upper gastrointestinal endoscopy was performed, which revealed an ulcerative lesion in the gastric antrum. A biopsy revealed Group 5, tub2, and HER2 negative, with PD-L1≥5%. cT3N1H1(M1 HEP), cStage ⅣB was diagnosed based on CT scan showing enlarged #8 lymph node and a single liver metastasis in the 2 cm range in S6 of the liver. The patient was deemed unresectable and was started on SOX plus nivolumab therapy. On day 11 after initiation, the patient had Grade 3 diarrhea by CTCAE v5.0, and S-1 was withdrawn for 3 days, but was administered for 2 courses. CT and MRI after chemotherapy showed shrinkage of both the primary tumor and liver metastases; R0 resection was deemed possible, and pyloric gastrectomy, D2 lymph node dissection, and partial hepatic S6 resection were performed. The histological evaluation of response to treatment was Grade 1b, and the patient was in ypStage ⅠA. The patient has been alive without recurrence for 6 months postoperatively while receiving S-1 monotherapy on an outpatient basis.

Abstract
This prospective study examined the associations of dog/cat ownership with incident disabling dementia using propensity score matching based on the physical, social, and psychological characteristics of dog and cat owners. We also examined associations of the interaction between dog/cat ownership and exercise habit and social isolation with dementia. Overall, 11,194 older adults selected using stratified and random sampling strategies in 2016 were analyzed. Dog/cat ownership was defined as "current" or "past and never". Disabling dementia was defined according to physicians' rating in the long-term care insurance system in Japan during the approximately 4-year follow-up period. Statistical analysis was weighted by the inverse of the propensity score in the generalized estimating equation after adjusting for follow-up period. Current dog owners (8.6 %) had an odds ratio (OR) of 0.60 (95 %CI: 0.37-0.977) of having disabling dementia compared to past and never owners. For cat ownership, the corresponding OR was 0.98 (95 %CI: 0.62-1.55). Current dog owners with a regular exercise habit had an OR of 0.37 (0.20-0.68) compared to past and never dog owners with no exercise habit. Further, current dog owners with no social isolation had an OR of 0.41 (0.23-0.73) compared to past and never dog owners with social isolation. Dog ownership had a suppressive effect on incident disabling dementia after adjusting for background factors over a 4-year follow-up period. Specifically, dog owners with an exercise habit and no social isolation had a significantly lower risk of disabling dementia.

Abstract
AIM To develop a rapid and easy screening tool to detect sarcopenia. METHODS In total, 683 community-dwelling older adults who participated in our cohort study, the "Otassha Study," in 2019, completely responded to a questionnaire, and were diagnosed with sarcopenia were included. Participants responded to a nine-item questionnaire, including candidate items for a new sarcopenia screening tool named rapid sarcopenia screening, based on items of the Strength, Assistance with walking, Rising from a chair, Climbing stairs, and Falls (SARC-F) questionnaire. To select appropriate items for the new screeening tool, multiple logistic regression analyses were performed, with sarcopenia as the dependent variable and questionnaire responses as independent variables. The area under the curve using 10 000 bootstraps was used to assess the rapid sarcopenia screening diagnostic ability for detecting sarcopenia. RESULTS Responses to question nos 2 (how much can you squeeze a wet towel?), 5 (how much muscle strength do you think you have compared with that of people of your age and sex?), 7 (how fast do you usually walk?), and 9 (age-related item) were related to sarcopenia in multiple logistic regression analysis. The area under the curve of the total score of rapid sarcopenia screening was 0.82, 0.80, and 0.81 for men, women, and overall, respectively. At a cut-off value of 14/15, the sensitivity and specificity for sarcopenia detection were 0.73 and 0.73, respectively. CONCLUSIONS The newly developed sarcopenia screening tool has a better diagnostic ability for sarcopenia than the SARC-F. Rapid sarcopenia screening does not require physical function measurements, making it a useful and accessible tool among older adults to detect sarcopenia. Geriatr Gerontol Int 2023; 23: 945-950.

OBJECTIVE The consumption of various foods is internationally recommended in healthy diet although the association between dietary variety and incident dementia is unknown. We aimed to examine the association between dietary variety and the incidence of disabling dementia in older Japanese adults. DESIGN We conducted a prospective cohort study. Dietary variety was assessed based on the Dietary Variety Score (DVS). DVS was assessed by counting the number of ten food components (meat, fish/shellfish, eggs, milk, soyabean products, green/yellow vegetables, potatoes, fruit, seaweed and fats/oils) that were consumed almost daily using a FFQ. Participants were categorised into low (0-2 points), middle (3-4 points) and high (5-10 points) groups based on the DVS. Data on newly diagnosed disabling dementia were retrieved from the public long-term care insurance database. Cox proportional hazards regression was used to estimate hazard ratios (HR) with 95 % CI. SETTING Yabu cohort study, Japan. PARTICIPANTS A total of 4972 community-dwelling adults aged 65 years or older. RESULTS During the median follow-up of 6·8 years, 884 participants were newly diagnosed with disabling dementia. After adjusting for confounders, the multivariable-adjusted HR for incident disabling dementia was 0·82 (95 % CI, 0·69, 0·97) for participants in the highest DVS category compared with those in the lowest DVS category (Pfor trend = 0·019). CONCLUSIONS A higher dietary variety is associated with a reduced risk of disabling dementia in older Japanese adults. These results have potential implications for the development of effective public nutritional approaches to prevent dementia in older adults.

Abstract
AIM To examine the effects of employment engagement, classified by frailty and working status, on the incidence of disability in urban community-dwelling older adults. METHODS We used data from 6386 initially nondisabled residents aged 65-84 years from Ota City, Tokyo, Japan, in 2016. The observation duration was 3.6 years. Self-administered questionnaires applied the Cox proportional hazard model by assessing the existence of frailty through Check-List 15 (with a score ≥4 indicating the state of frailty), controlling for age, sex, living situation, education level, equivalent income, chronic conditions, body mass index, instrumental activities of daily living, self-rated health, drinking and smoking status, and social activities. We evaluated the predictive value of working status (full-time, part-time, temporary, or nonworker) at baseline for cause-specific disability (dementia-type vs. non-dementia-type) incidence, identified using the long-term care insurance system's nationally unified database. RESULTS Of the 6386 participants, 806 (63/1134 full-time workers; 58/1001 part-time workers; 61/547 temporary workers; 624/3704 nonworkers) presented with disabilities during the 3.6-year-long duration. Adjustments for conventional covariates showed that nonfrail full-time and part-time workers, as well as frail full-time workers, had significantly lower risks of all-cause disability incidence. Furthermore, nonfrail and frail full-time workers had significantly lower risks of dementia-type and nondementia-type disabilities, respectively. CONCLUSIONS The incidence of disability in older adults was influenced by working and frailty status. Engaging in full-time work thus prevents disabilities in older adults, regardless of their frailty status. Meanwhile, nonfrail older adults are able to avoid disabilities even when engaging in part-time work. Geriatr Gerontol Int 2023; 23: 855-863.

Abstract
OBJECTIVE The masticatory function is intricately linked to several factors like natural teeth count, occlusion, masticatory muscles, and tongue coordination. This study's goal was to formulate a comprehensive masticatory function model, considering sarcopenia's conceptual structure, and subsequently validate its measurement efficacy. DESIGN The study encompassed 753 participants (59.1 % women; mean age: 73.0 ± 5.1 years) from an urban community. The model amalgamated masseter muscle mass, occlusal force, and mixing ability. Based on the Asian Working Group for Sarcopenia 2019 classification, participants were categorized into a multiple masticatory dysfunction (MMD) or severe MMD (S-MMD) group. Logistic regression analysis gauged the model's validity, using serum albumin levels and self-reported chewing difficulties as dependent variables. RESULTS Of the total, 61 (8.1 %) participants exhibited MMD, while 24 (3.2 %) had S-MMD. S-MMD was correlated with low serum albumin levels (odds ratio: 3.62; 95 % confidence interval: 1.07-12.29) and heightened self-reported chewing difficulties (odds ratio: 2.82; 95 % confidence interval: 1.09-7.28). CONCLUSIONS Our multiple masticatory function model offers a straightforward approach for assessing MMD. Furthermore, the study establishes a link between S-MMD, nutritional vulnerability, and self-reported chewing challenges, thus affirming the model's credibility.

Abstract
BACKGROUND The frequency of combined declines in domains of multi-faceted frailty and their impact on adverse health outcomes have not been adequately investigated. We aimed to examine the association between combined subscale declines in higher-level functional capacity and 8-year all-cause mortality among community-dwelling older Japanese individuals and the impact of multi-faceted frailty on mortality. MATERIALS AND METHODS We administered a questionnaire to 7015 community-dwelling older adults aged 65-85 years. The higher-level functional capacity of the 3381 respondents was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Subscale decline was defined as (1) none, (2) only social role (SR), (3) only intellectual activity (IA), (4) SR and IA, (5) only instrumental activities of daily living (IADL), (6) IADL and SR, (7) IADL and IA, and (8) all. Associations between combined subscale declines and mortality were examined using adjusted Cox proportional hazards models. Follow-up was conducted from October 1, 2012, to death or November 1, 2020. RESULTS The mortality rate was 16.7/1000 person-years. Moreover, 44% of respondents had declined SR, and half of them had multiple declines. Compared with no decline, SR (adjusted hazard ratio [HR]: 1.49, 95% confidence interval [CI]: 1.14-1.93), SR and IA (HR: 1.59, 95% CI: 1.16-2.17), IADL and SR (HR: 1.97, 95% CI: 1.31-2.99), and all-domain (HR: 2.72, 95% CI: 1.98-3.74) declines were significantly associated with higher mortality risks. CONCLUSIONS Overlapping SR and IADL declines increased mortality risk, suggesting the importance of measuring social frailty and overlapping physical and social frailty.

Abstract
The patient is a 72-year-old man. He was diagnosed as a duplication of left upper lobe lung adenocarcinoma cStage ⅣB and transverse colon cancer cStage Ⅳc. Because he had symptoms of atelectasis and esophageal stricture due to the progression of lung cancer, we decided to precede immunochemotherapy(CBDCA plus PEM plus pembrolizumab)for lung cancer. After the start of treatment, both lung and colorectal cancer were shrinking, but after the 3 courses of treatment, he developed intestinal obstruction due to transverse colon cancer. Because generalized peritonitis due to perforation of the colon by endoscopic stenting for the obstruction and then emergency surgery was performed. The resected transverse colon lesion was diagnosed as pathologically complete response. Lung cancer was also diagnosed as clinically complete response. Since his ADL decreased postoperatively, he is under observation without reintroduction of immunochemotherapy. Fourteen months have passed since the last administration, and no progression has been observed in either lung nor colon cancers. Pembrolizumab is considered to be successful in the patient with dMMR colorectal cancer lacking MLH1 and PMS2.

Abstract
AIM To assess the validity of self-reported articulatory oral motor skill against objectively measured repetitive articulatory rate (oral diadochokinesis [oral-DDK]) as a gold standard index for articulatory oral motor skill in community-dwelling older Japanese adults. METHODS This cross-sectional study included 607 Japanese adults (mean age = 73.9 years). A single-item self-report questionnaire for articulatory oral motor skill was developed. Study participants completed a 1-month-interval test-retest protocol to assess reliability of the questionnaire, and the protocol was tested by the kappa statistic. Oral-DDK with /ta/ (i.e., the number of repetitions of the monosyllable /ta/ per second) was measured during the on-site examination. Low oral-DDK performance was defined as <5.2 times/s in men and <5.4 times/s in women. Oral-DDK performance, oral functions other than articulatory oral motor skill, and physical frailty were compared in the groups with and without self-reported low articulatory oral motor skill as determined by the response to the questionnaire. RESULTS Self-reported low articulatory oral motor skill was identified in 18.5% of the study population. The self-report questionnaire had good test-retest reliability, with a kappa statistic of 0.71. Self-reported low articulatory oral motor skill was significantly associated with a lower value of oral-DDK with /ta/ and a higher proportion of low oral-DDK performance, difficulties in chewing and swallowing, dry mouth, and physical frailty. Self-report had high specificity (83.1%) but low sensitivity (42.1%) for detecting low oral-DDK performance. CONCLUSIONS A single-item self-report questionnaire for articulatory oral motor skill had acceptable test-retest reliability and was associated with objectively measured articulatory oral motor skill.

Abstract
AIM This study aimed to develop a patient-centred handbook that integrates information on lifestyle modifications and psychological support strategies for individuals with mild cognitive impairment (MCI). This article provides a comprehensive record of the development process. METHODS We adopted a participatory research model for the methodology, which comprised five phases and involved an interdisciplinary team specializing in dementia and health literacy. Data were initially collected via interviews conducted among patients with MCI (n = 5) and their families (n = 5). Given the study's preliminary nature, depth and richness of the qualitative data were the key concerns for determining the sample size, rather than broad generalizability. We ensured the inclusion of diverse experiences and perspectives by facilitating the creation of patient questions (PQs) that merged scientific evidence with patient perspectives. To enhance the handbook's accessibility and utility, we continuously evaluated the same using patient interviews, health literacy tool assessments and team discussions. This comprehensive approach harmonized scientific knowledge and patient experience, leading to the development of a personalized MCI management guide. RESULTS The handbook comprises nine domains, encompassing 38 selected PQs: MCI, lifestyle, lifestyle-related diseases, exercise, nutrition, social participation, cognitive training, psychological care and family support. The health literacy handbook was evaluated based on Clear Communication Index scores. The results revealed that 73.7% of the PQs were deemed difficult prerevision, whereas only 5.3% remained challenging postrevision. The formative evaluation underscored the need for more detailed explanations prerevision, whereas postrevision comments focused primarily on editorial suggestions. CONCLUSION The inclusion of patients' perspectives right from the outset ensured that the handbook met their specific needs. The final version, which reflects all stakeholders' inputs, is now slated for imminent publication. PATIENT OR PUBLIC CONTRIBUTION Patients and the public participated extensively throughout the project, from initial interviews to material evaluation and refinement.

Abstract
For the practical implementation of microdisk resonators as active nanophotonic devices, it is essential that they can be electrically driven. However, it is difficult to inject current in such small-scale devices without severely degrading their optical properties. We demonstrate the successful fabrication of an electrically injected microdisk based on Eu-doped GaN, in which an SiO2 spacer is used to prevent the interaction of the metal contact with the optical resonances. The microdisk shows Eu-related emission upon electrical injection and from the observed resonance peak, a cavity quality (Q)-factor of 3400 is concluded.

Abstract
AIM To evaluate the association between vitamin D status and periodontal inflammation as determined by the periodontal inflamed surface area (PISA) in community-dwelling older adults. MATERIALS AND METHODS This cross-sectional study included 467 Japanese adults (mean age = 73.1 years) who underwent full-mouth periodontal examinations and measurements of serum levels of 25-hydroxyvitamin D (25(OH)D). We used linear regression and restricted cubic spline models to analyse the association between exposure (serum 25(OH)D) and outcome (PISA). RESULTS The linear regression model showed that, after adjusting for potential confounders, participants in the lowest quartile of serum 25(OH)D had 41.0 mm2 more PISA (95% confidence interval [CI]: 4.6-77.5) than the reference group (the highest quartile of serum 25(OH)D). The spline model showed that the association between serum 25(OH)D and PISA was non-linear and restricted to the low 25(OH)D range. PISA initially sharply decreased as serum 25(OH)D increased, and then the decreasing trend slowed and plateaued. The inflection point with the minimum PISA value was a serum 25(OH)D level of 27.1 ng/mL, above which there was no decreasing trend in PISA with increasing serum 25(OH)D levels. CONCLUSIONS Low vitamin D status had an L-shaped association with periodontal inflammation in this cohort of Japanese adults.

Abstract
Introduction This longitudinal study aimed to identify aging trajectory patterns of social interaction by sex and determine the association between these patterns and all-cause mortality. Methods Participants were 4,065 community-dwelling older adults (1849 men) in Japan, aged 65-89 years, who responded twice or more to a mail survey conducted between 2012 and 2020. Social interaction was examined through the frequency of face-to-face and non-face-to-face contact with non-resident family and friends. The aging trajectories of the social interaction scores were identified using group-based trajectory modeling. Results Two groups were identified among both men and women. Among men with high-frequency interaction, a rapid decrease in the frequency of social interaction was observed after 80 years of age. Conversely, among women, the frequency tended to remain the same, even after 80 years of age. The social interaction score among those aged 65 years in the low-frequency group was approximately 4 points for men and 6 points for women. Among men, no decrease was observed; however, it tended to decline after 85 years of age among women. Among men, the factors associated with the low-frequency group were instrumental activities of daily living score, perceived financial status, and social participation, while among women, they were self-rated health and social participation. The adjusted hazard ratio in the low-frequency group for all-cause mortality was 1.72 (95% confidence interval, 1.27-1.72) for men and 1.45 (95% confidence interval, 0.98-2.14) for women. Discussion In the low-frequency group, men had a higher risk of all-cause mortality than women. Daily social interaction from mid-age is important to reduce the risk of social isolation and all-cause mortality in later life.

Abstract
INTRODUCTION We examined the relationship between previous fluctuations in Mini-Mental State Examination (MMSE) scores, future changes in MMSE scores, and attrition from follow-up surveys, which helps in a more comprehensive interpretation of repeatedly collected MMSE scores. METHODS This 4-year longitudinal study included 2,073 community-dwelling older adults aged ≥65 years in Japan. The MMSE was administered at baseline (T0), 2 years (T1), and 4 years (T2) follow-up. We performed multinomial logistic regression analysis with the dependent variable, indicating the change in MMSE score from T1 to T2 (categorized as increase, no change [reference category], and decrease) and attrition at T2. The independent variables included the change in MMSE scores from T0 to T1 and MMSE scores at T0 and T1. RESULTS The mean MMSE score was 29 across the three time points. A one-point decrease in MMSE score from T0 to T1 was associated with 79% (95% confidence interval: 1.62, 1.97) higher odds of an increase in MMSE score from T1 to T2 and 28% (1.17, 1.40) higher odds of attrition at T2. A one-point decrement in the MMSE score at T0 and T1 was also associated with an increase in the MMSE score from T1 to T2 and attrition at T2. CONCLUSION Focusing on cognitive fluctuation for 2 years, rather than cognitive function at a point in time, would have no remarkable advantage when focusing on future cognitive function and attrition. Our results emphasize the need for further studies to identify factors that distinguish between those who continue to attend follow-up surveys and show improvements in cognitive test scores and those who drop out.

Abstract
BACKGROUND/AIM Laparoscopic distal gastrectomy for gastric cancer has become a common procedure in many institutions. As manual palpation is impossible, various methods have been developed to identify the location of the tumor and determine the proximal resection line. Intraoperative endoscopy requires manpower and is time-consuming. The authors take an intraoperative X-ray. Here, we demonstrate our methods and outcomes. PATIENTS AND METHODS We preoperatively applied metal clips just proximal to the tumor through esophagogastroduodenoscopy. During surgery, we applied metal vessel clips to the greater and lesser curvatures of the planned resection line of the stomach and took an intraoperative X-ray to examine the distance between the planned resection line and the tumor. If the distance was appropriate, the stomach was resected on the planned line, and if the distance was judged to be insufficient, the stomach was resected on the more proximal line, as appropriate. An intraoperative frozen section of the proximal resection margin was examined, as appropriate. RESULTS We performed this method for 71 patients. Tumors were successfully resected together with preoperative endoscopic clips in all patients. In five patients, intraoperative frozen section of the proximal resection margins was positive; however, additional resection confirmed negative margins. One patient underwent total gastrectomy, and the remaining 70 patients underwent distal gastrectomy. CONCLUSION An intraoperative X-ray seems to be a simple and useful method for identifying the location of the tumor and determining the proximal resection line.

Abstract
We previously experienced two cases of end sigmoid colostomy reconstruction via the extraperitoneal route at the same site as the transperitoneal loop stoma. For an anterior rectus fascia, the transperitoneal route used closed intraperitoneal interrupted sutures and continuous sutures with barbed sutures. A new extraperitoneal route was established through the sutured anterior rectus sheath. Before reconstructing the end stoma, a subcutaneous purse-string with monofilament absorbable sutures tied to create an approximately 2.5 cm diameter was used. There were no early complications associated with the stoma. One year after surgery, a parastomal hernia was not defined. Using the presented technique, two cases were successfully recreated extraperitoneally at the same site's end stoma.

Abstract
BACKGROUND As the older population increases, the need for early detection of cognitive decline is also increasing. In this study, we examined whether our paper-pencil type group examination for cognitive assessment (PAPLICA) could detect the effects of years of education and aging. METHODS PAPLICA was conducted on 829 older people. The inclusion criteria were age 60 years or older and the ability to come to the event site alone. The exclusion criteria were participants with a medical or psychiatric disorder or dementia.One examiner conducted the test on a group of approximately 10-20 people in approximately 25 min. Participants were instructed on tackling the issues projected on the projector, and their answers were recorded in a response booklet. RESULTS An independent sample t-test was performed for years of education, and ANCOVA was performed for aging. Among the test items included in PAPLICA, the Speed I and Letter fluency tests were unable to detect the effects of aging. Furthermore, the age at which the effect of aging manifests varies depending on the test item. For instance, a decline in scores in the Speed I and Picture ECR Free recall tests was observed in the 70-74 age group; for that of Word DRT, Picture ECR cued recall, and Similarity, in the 75-79 age group; for CFT, in the 80-84 age group, and for CLOX, the decline was observed in the 85 ≤ age group. CONCLUSIONS PAPLICA, similar to other neuropsychological tests, was able to detect the effects of years of education and aging. Future testing should be conducted on different demographics to identify the differences in patterns of cognitive decline.

Abstract
BACKGROUND Research has suggested an association between lower socioeconomic status (SES) and unhealthy dietary habits. However, differences in the effects of different SES indicators and age remain unclear. The current study addressed this research gap by investigating the relationship between SES and unhealthy dietary habits, specifically focusing on educational attainment and subjective financial status (SFS) among varied age groups. METHODS Data were derived from a mail survey of 8,464 people living in a suburb of Tokyo, Japan. Participants were classified into three age groups (20-39 years: young adults; 40-64 years: middle-aged adults; and 65-97 years: older adults). SES was assessed based on individual educational attainment and SFS. Unhealthy dietary habits were defined as skipping breakfast and a low frequency of balanced meal consumption. Participants were asked how often they ate breakfast, and those who did not respond "every day" were categorized as "breakfast skippers." Low frequency of balanced meal consumption was defined as eating a meal that included a staple meal, main dish, and side dishes at least twice a day for less than five days per week. Poisson regression analyses with robust variance adjusted for potential covariates were used to determine the interactive effects of educational attainment and SFS on unhealthy dietary habits. RESULTS Individuals with lower educational attainment across all age groups skipped breakfast more frequently compared to those with higher educational attainment. For older adults, poor SFS was associated with skipping breakfast. Young adults with poor SFS and middle-aged adults with lower educational attainment tended to eat less balanced meals. In addition, an interaction effect was found in older adults, where those with lower education despite good SFS and those with poor SFS despite higher education were at a greater risk of falling into unhealthy diet. CONCLUSIONS The findings suggested that different SES indicators affect healthy dietary habits in different generations, and therefore, health policies should consider the potential influence of different SES on promoting healthier dietary habits.

Abstract
Generativity is defined as an individual's concern for and actions dedicated toward the well-being of others, especially youth and subsequent generations. It is a key stage of psychological development from midlife to older age and can be a guiding concept for promoting engagement of older adults in productive and contributive activities, which benefit their well-being. This study examined the longitudinal association between generativity and higher-level functional capacity (HLFC) decline in older Japanese adults. The two-year longitudinal data of 879 older adults aged 65-84 years were analyzed. Participants' HLFC and generativity were assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence and the Revised Japanese version of the Generativity Scale, respectively. The binary logistic regression analysis results showed that a higher generativity score was negatively associated with HLFC decline, indicating that generativity effectively prevents HLFC decline over 2 years. On adding the interaction term between generativity and sex to examine whether the protective effect of generativity differed by sex, we found that generativity was especially effective in protecting the HLFC decline in men with higher generativity. The study results highlight the importance of promoting engagement of older adults in generative activities to maintain their HLFC.

Abstract
Objectives This study is intended to clarify the perceived benefits of working among older assistant care workers employed in geriatric health service facilities and examine the relationship between perceived benefits and emotional exhaustion.Methods We analyzed data from a mail survey of older assistant care workers employed in geriatric health service facilities that the Japan Association of Geriatric Health Services Facilities conducted in 2020. In this survey, those aged ≥60 were defined as older assistant care workers. Responses were obtained from 1,606 older assistant care workers at 599 facilities. The dependent variable was the emotional exhaustion subscale of the Japanese version of the Burnout Questionnaire. The independent variables were the seven benefits of working as an assistant care worker: 1) I can contribute to society; 2) I am connected to society; 3) I have a sense of purpose in life; 4) I am earning the income I expected since I started working as an assistant care worker; 5) I am learning about care; 6) It has maintained and improved my health; and 7) I can use my time effectively. Latent class analysis (LCA) was performed using these seven benefits as independent variables. Multiple regression analysis was performed using emotional exhaustion and the perceived benefits as dependent and independent variables, respectively. The missing values were supplemented by the multiple imputation method.Results Overall, 1,601 responses were analyzed after excluding 5 respondents who did not answer all the questions. Four patterns were identified from the LCA results: the "benefit-full type," who perceived all benefits; the "benefit-less type," who perceived few benefits; the "benefit-extroverted type," who perceived social contribution and connection as benefits; and the "benefit-introverted type," who perceived health maintenance and improvement and time utilization as benefits. The multiple regression analysis showed that emotional exhaustion scores were higher for the "benefit-extroverted" and "benefit-less" types than for the "benefit-full" type (b=2.465, P<.001 and b=1.931, P<.001, respectively). No difference was found in the case of the "benefit-introverted" type (b=0.050, P=.851).Conclusion The perceptions of diverse and introverted benefits were associated with lower emotional exhaustion scores among older assistant care workers. Future intervention studies are needed to examine whether obtaining diverse or introverted benefits can decrease the emotional exhaustion score.

Abstract
BACKGROUND/AIM To ascertain whether preoperative neo-adjuvant nutritional therapy (NANT) using eicosapentaenoic acid (EPA) supplementation can provoke a rise in blood levels of EPA capable of restricting NF-B nuclear translocation in resected specimens. PATIENTS AND METHODS Patients were allocated to two groups depending on individual preference: Patients in the treatment group received 2 g of EPA daily for two weeks prior to surgery (NANT group, n=18). Patients in the control group had a normal diet (CONT group, n=26). NF-B translocation rate, in specimens collected, was investigated by histopathology. Five hundred malignant cells were counted, and tissues with 10% or higher NF-B nuclear translocation were determined to be positive. RESULTS The EPA blood concentration rose significantly in the NANT group (p<0.01). The positive rate of NF-B nuclear translocation in cancer cells was 11.1% in the NANT group compared with 50% in the CONT group. This difference was statistically significant (p<0.01). CONCLUSION Increased blood concentrations of EPA after preoperative supplementation was associated with suppression of NF-B nuclear translocation in malignant cells. These results suggest that intake of EPA-containing supplements before surgery can control NF-B activation and by extension, cancer aggressiveness.

Abstract
BACKGROUND No easy-to-use fall risk assessment tools have been devised to assess occupational fall risk in older workers. AIMS To develop an Occupational Fall Risk Assessment Tool (OFRAT) and report its predictive validity and reliability in older workers. METHODS The baseline fall risk assessment was completed by 1113 participants aged ≥60 years who worked ≥4 days/month in Saitama, Japan. Participants were followed up for falls during occupational activities for 1 year, and 30 participants were assessed twice for test-retest reliability. The following assessment measures were summed to form the OFRAT risk score: older age, male sex, history of falls, physical work participation, diabetes, use of medications increasing fall risk, reduced vision, poor hearing, executive dysfunction and slow stepping. The scores were then classified into four grades (0-2 points: very low, 3 points: low, 4 points: moderate and ≥5 points: high). RESULTS During follow-up, 112 participants fell 214 times during work. The negative binomial regression model showed that participants with higher grades had a higher incidence rate ratio [95% confidence interval] for falls than those with very low grades (low: 1.64 [1.08-2.47], moderate: 4.23 [2.82-6.34] and high: 6.12 [3.83-9.76]). The intraclass correlation coefficient for risk score was 0.86 [0.72-0.93], and the weighted kappa coefficient for grade assessment was 0.74 [0.52-0.95]. CONCLUSIONS The OFRAT is a valid and reliable tool for estimating the occupational fall risk in older workers. It may assist occupational physicians implement strategies to prevent falls in this group.

Abstract
IntroductionThis study examined whether the association between sarcopenia severity and cognitive function differed according to sex and age in community-dwelling older adults in Japan.MethodsThis is a cross-sectional study of older adults (age ≥ 65 years) consisting of five regional cohorts integrated as the Integrated Research Initiative for Living Well with Dementia (IRIDE) Cohort Study. Sarcopenia severity was determined based on the Asian Working Group for Sarcopenia 2019, which assessed grip strength, walking speed, and skeletal muscle mass index. Poor cognitive function was defined as a Mini-Mental State Examination score of ≤ 23. Odds ratios (ORs) and 95% confidence intervals (CIs) for poor cognitive function were calculated by sex and age group (65–74 and ≥75 years) using binomial logistic regression models, which were adjusted for age, educational attainment, history of non-communicable diseases, smoking and drinking habits, living alone, frequency of going outdoors, exercise habits, and depressive symptom.ResultsOf the 8,180 participants, 6,426 (1,157 men aged 65–74 and 1,063 men aged 75 or older; 2,281 women aged 65–74 and 1,925 women aged 75 or older) were analyzed. The prevalence ratio of sarcopenia and severe sarcopenia were 309 (13.9%) and 92 (4.1%) among men and 559 (13.3%) and 166 (3.7%) among women, respectively. A total of 127 (5.8%) men and 161 (3.9%) women had a poor cognitive function. Setting non-sarcopenia as a reference, the adjusted ORs (95% CI) of poor cognitive function were 2.20 (1.54, 3.15) for sarcopenia and 3.56 (2.20, 5.71) for severe sarcopenia. A similar trend was observed in analyses stratified by sex and age, with linear associations (P for trend <0.05) in both categories. Furthermore, there was a significant interaction (P < 0.05) between sex and sarcopenia severity, indicating a stronger linear association of sarcopenia severity with poor cognitive function in women compared with men.Discussion and conclusionSarcopenia severity was linearly associated with poor cognitive function in adults aged ≥ 65 years, with a stronger association in women compared with men.

Abstract
A 68-year-old male patient was referred to our hospital because of unfit to treat his recto-sigmoidal cancer massively invaded to bladder at the former hospital. During drug administration to treat heart failure, we could perform a transverse colostomy and initiated mFOLFOX plus Pmab. During chemotherapy, he improved malnutrition. After 7 courses, CT scan showed a marked reduction in tumor diameter, which was PR. Since his nutritional and heart status were improved, he underwent a high anterior resection with partial bladder resection. Pathological findings showed that a few cancer cells were remained at bladder and bowel wall. He was diagnosed as Stage Ⅱc. His postoperative course was almost uneventful. No symptom of recurrence has been observed at 9 months after surgery without adjuvant chemotherapy.

Abstract
BACKGROUND Preoperative inflammatory or nutritional biomarkers and clinicopathological features may be survival predictors in resectable esophageal squamous cell carcinoma. METHODS We included 118 patients with resectable squamous esophageal carcinoma (stages I-IV), assessing preoperative CRP- and albumin-based modified Glasgow prognostic score, the modified controlling nutritional status score, C-reactive protein, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, pathologic stage, and tumor location(s), looking for correlation with overall survival and relapse-free survival. Using univariate and Cox analysis, we selected the most reliable prognostic factors. RESULTS Five-year overall survival and recurrence-free survival were 54.9% and 48.5%, respectively. C-reactive protein values correlated negatively with hypoalbuminemia (P = 0.0036). On univariate analysis, tumor stage, invasion depth, location, nodal involvement, albumin, and modified Glasgow prognostic score were significant prognostic factors for overall and recurrence-free survival. Preoperative C-reactive protein was prognostic factor for overall survival, but not for relapse-free survival (P = 0.017, 0.063, respectively). The Cox proportional hazards model showed the modified Glasgow prognostic score to be an independent prognostic factor for relapse-free survival and overall survival after using the stepwise variable selection procedure. Cox analysis including clinicopathological factors and modified Glasgow prognostic scores showed that only tumor location(s) and pathologic stage were independent prognostic factors for overall survival and recurrence-free survival. CONCLUSION Although the modified Glasgow prognostic score is not superior to pathologic stage and tumor location as a biomarker of preoperative nutrition/inflammation and clinicopathological factors, it remains an important prognostic marker in resectable esophageal cancers. Preoperative decreased inflammatory response and improved nutritional status may contribute to prognosis in patients with esophageal cancer.
