Abstract
Small-cell lung cancer (SCLC) is an aggressive cancer for which immune checkpoint inhibitors (ICI) have had only limited success. Bispecific T-cell engagers are promising therapeutic alternatives for ICI-resistant tumors, but not all patients with SCLC are responsive. Herein, to integrate CD137 costimulatory function into a T-cell engager format and thereby augment therapeutic efficacy, we generated a CD3/CD137 dual-specific Fab and engineered a DLL3-targeted trispecific antibody (DLL3 trispecific). The CD3/CD137 dual-specific Fab was generated to competitively bind to CD3 and CD137 to prevent DLL3-independent cross-linking of CD3 and CD137, which could lead to systemic T-cell activation. We demonstrated that DLL3 trispecific induced better tumor growth control and a marked increase in the number of intratumoral T cells compared with a conventional DLL3-targeted bispecific T-cell engager. These findings suggest that DLL3 trispecific can exert potent efficacy by inducing concurrent CD137 costimulation and provide a promising therapeutic option for SCLC.

Abstract
AIM This study investigated work impairment and its associated factors among geriatricians during the coronavirus disease 2019 (COVID-19) pandemic. METHODS This cross-sectional study was carried out using an anonymous online survey questionnaire administered to members of the Japanese Geriatric Society between October and December 2022. The questionnaire included questions regarding psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale) and work impairment (Work Functioning Impairment Scale). Multivariate logistic regression analyses were carried out to determine the factors associated with work impairment. Causal mediation analyses were performed to delineate the relationship between work impairment, psychological distress and fear of COVID-19. RESULTS The analytic sample included 386 geriatricians, and work impairment was observed in 24.8% of them. Work impairment was associated with age, prefecture where the institution was located and fear of COVID-19. Mediation analysis showed that the effect of fear of COVID-19 on work impairment was almost completely mediated by psychological distress. CONCLUSION During the COVID-19 pandemic, work impairment was commonly observed among geriatricians. We found that fear of COVID-19 might cause work impairment; however, this effect was exerted entirely through psychological distress. This implies that interventions to prevent or reduce work impairment among doctors should mainly target psychological distress; however, the fear of COVID-19, if it causes psychological distress, should also be addressed. Managers of hospitals and long-term care facilities must take steps to protect healthcare workers' mental well-being and maintain work productivity. Therefore, understanding the factors related to work impairment might help them devise effective measures. Geriatr Gerontol Int 2024; 24: 215-220.

Abstract
Older people's health condition is not uniform, and the components of their health are interrelated. Concepts regarding the health of older people have emerged and changed over time. However, the transition of concepts and influencing factors are not well examined through research. We have conducted a scoping review of the changes over time in the concept of health for older people and the factors influencing these changes. The public websites of international organizations and academic societies related to older people's health and research paper database were searched, and the extracted data were summarized in a chronological table. Consequently, this study revealed changing trends in health orientation after health had been defined by WHO, namely, successful aging, productive aging, active aging, and healthy aging, and their components, not the concept of health. The emergence and changes of health orientation among older people may have accompanied proposals and measures of international organizations and academic societies developed in response to changes in the demographic structure, and changes in how society perceives and supports older people. With the changing eras that bring about advances in health technology, prolongation of life expectancy, and changes in lifestyles, the needs of older people, society's perceptions of aging and older people, and how to support them will also change. Our findings may provide a valuable basis for understanding aging and older people, reconsidering their health orientation based on the health issues of older people and their significance, and formulating policies for older people in the future.

Abstract
In human celiac disease (CeD) HLA-DQ2.5 presents gluten peptides to antigen-specific CD4+ T cells, thereby instigating immune activation and enteropathy. Targeting HLA-DQ2.5 with neutralizing antibody for treating CeD may be plausible, yet using pan-HLA-DQ antibody risks affecting systemic immunity, while targeting selected gluten peptide:HLA-DQ2.5 complex (pHLA-DQ2.5) may be insufficient. Here we generate a TCR-like, neutralizing antibody (DONQ52) that broadly recognizes more than twenty-five distinct gluten pHLA-DQ2.5 through rabbit immunization with multi-epitope gluten pHLA-DQ2.5 and multidimensional optimization. Structural analyses show that the proline-rich and glutamine-rich motif of gluten epitopes critical for pathogenesis is flexibly recognized by multiple tyrosine residues present in the antibody paratope, implicating the mechanisms for the broad reactivity. In HLA-DQ2.5 transgenic mice, DONQ52 demonstrates favorable pharmacokinetics with high subcutaneous bioavailability, and blocks immunity to gluten while not affecting systemic immunity. Our results thus provide a rationale for clinical testing of DONQ52 in CeD.

Abstract
Abstract
Background: Despite the approval of immune checkpoint inhibitors (ICIs), prognosis of small cell lung cancer (SCLC) remains poor. DLL3 is upregulated in SCLC whereas expression in normal tissues is minimal, representing the favorable profile as a therapeutic target. T cell engager (TCE) is a potent immunotherapy that redirects T cells to tumors expressing a specific antigen. Unlike ICIs, TCEs do not require the recognition of tumor antigens by T cells and thus could be an alternative approach to target tumors where the benefit of ICIs is limited such as SCLC. CD137 (4-1BB) is a costimulatory molecule that promotes T cell activation, proliferation, and survival. Since CD137 agonists synergize with CD3-mediated T cell activation, inducing concurrent CD137 costimulation is a promising strategy to unleash the potential of TCEs. We therefore developed a DLL3/CD3/CD137 trispecific T cell engager composed of two CD3/CD137 dual specific Fabs and one extra DLL3 Fab (DLL3 trispecific, RG6524).
Results: We initially investigated the CD3 and CD137 signal transduction in Jurkat cells harboring NFAT or NF-κB reporter cocultured with DLL3 positive cells. DLL3 trispecific showed dose-dependent increase in NFAT and NF-κB activity, indicating that target engagement successfully activated CD3 and CD137 signaling. In the in vitro assay using human PBMC, DLL3 trispecific induced cytotoxicity against SCLC cell lines with EC50s in the two-digit pM range.
In vivo efficacy was evaluated in SCLC xenograft models established by engrafting SCLC cell lines into immune humanized NOG mice. DLL3 trispecific showed greater tumor growth inhibition compared to a traditional bispecific T cell engager. Furthermore, flow cytometry-based immunophenotyping revealed that DLL3 trispecific increased T cell number in tumors and improved IFN-γ production from CD8 T cells. We also explored the combination with platinum-based drugs, which are widely used for SCLC, and showed that DLL3 trispecific enhanced the efficacy of platinum-based drugs. These data demonstrated that DLL3 trispecific has the potent in vivo efficacy and the potential for clinical use.
We next evaluated whether cytokine release syndrome (CRS) mitigating approaches affect antitumor efficacy. Although prophylactic use of a steroid significantly reduced cytokine production, tumor growth inhibition by DLL3 trispecific remained unchanged. Likewise, tocilizumab treatment did not reduce the efficacy, suggesting that CRS mitigation did not abrogate the therapeutic benefit.
We finally assessed the tolerability in non-human primates. DLL3 trispecific did not reach the maximum tolerated dose and was well tolerated up to 16 mg/kg Q2D, the highest dose tested.
Conclusion: Our data showed that DLL3 trispecific has potent activity and is well suited for clinical application in SCLC. These findings provide a rationale for the clinical testing of DLL3 trispecific.

Abstract
OBJECTIVES As disasters become more frequent because of global warming, countries across the world are seeking ways to protect vulnerable older populations. Although these conditions may increase nursing home admission (NHA) rates for older persons, we know of no studies that have directly tested this hypothesis. DESIGN This was a retrospective cohort study. SETTING AND PARTICIPANTS We analyzed data from long-term care insurance (LTCI) users in 3 Japanese prefectures that incurred heavy damage from the 2018 Japan Floods, which is the largest recorded flooding disaster in national history. Specifically, we extracted NHA data from the LTCI comprehensive database, both for disaster-affected and unaffected individuals. METHODS We employed the Cox proportional hazards model to calculate multivariate-adjusted hazard ratios (HRs) for NHAs within a 6-month period following the 2018 Japan Floods, with adjustments for potential confounding factors. RESULTS Of the 187,861 individuals who used LTCI services during the investigated period, we identified 2156 (1.1%) as disaster affected. The HR for NHA was significantly higher for disaster-affected (vs unaffected) individuals (adjusted HR 3.23: 95% CI 2.88‒3.64), and also higher than the HRs for older age (90-94 years vs 65-69 years: 2.29, CI 1.93‒2.70), cognitive impairment (severe impairment vs normal: 1.40, CI 1.25‒1.57), and physical function (bedridden vs independent: 2.27, CI 1.83‒2.70). According to our subgroup analyses, the adjusted HR for disaster-affected individuals unable to feed themselves was 6.00 (CI 3.68‒9.79), with a significant interaction between the 2 variables (P = .01). CONCLUSIONS AND IMPLICATIONS Natural disasters increase the risk of NHA for older persons, especially those who are unable to feed themselves. Health care providers and policymakers should understand and prepare for this emerging risk factor.

Abstract
AIMS To investigate the influence of disability severity level on polypharmacy and the prescription of potentially inappropriate medication (PIM) using health insurance and long-term care (LTC) insurance claim data. METHODS Data were obtained from a health-care insurance and long-term care insurance claims database of citizens of Kure city, Japan, in April 2017. Data including age, sex, and drug profile were obtained, and the level of LTC needs was used to measure disability level. Factors associated with polypharmacy (≥5 prescribed drugs) and PIM prescription (≥1 PIM) defined by STOPP-J were analyzed statistically. RESULTS Among 67,169 people aged ≥65 (mean age 77.2 ± 7.9, male 40.7%), the frequency of polypharmacy increased with age until 85-89 (male 58.3%, female 57.6%) in both genders, and polypharmacy was most prevalent in those at the mildest LTC level (support level: male 68.9%, female 73.7%). PIM prescriptions was also frequent in those with LTC needs. On multiple logistic regression analysis, polypharmacy was significantly associated with older age and LTC needs, and PIM prescription was associated with older age and higher LTC level, suggesting that there is a large difference in prescription according to the person's age and disability level. CONCLUSION Polypharmacy was prevalent especially in older persons which peaked at the age of 85-89 or at mild disability level, and PIM prescription was prevalent in those with older age and higher care levels. When optimizing polypharmacy or PIM prescription in older patients, healthcare providers should focus on not only age but also disability level.

Abstract
BACKGROUND This study aimed to develop a self-assessment scale for care management of people with dementia and examine its reliability and validity. METHODS Based on Bloom's Taxonomy, previous research, and experts' opinions on dementia and care management, a scale consisting of 18 items was developed to assess care managers' attitudes, knowledge, and skills in their management of people with dementia. To examine the scale's reliability and validity, data were collected from 638 care managers. Construct validity using exploratory factor analysis, known-group validity, and internal consistency reliability of the scale were evaluated. RESULTS Exploratory factor analysis supported the construct validity with a four-factor model and explained 59.1% of the total variance. Following were the four factors: Factor I 'Person centred care'; Factor II 'Understanding of disease characteristics, treatment and care'; Factor III 'Understanding of people with dementia and care management according to their characteristics'; and Factor IV 'Utilization of local resources surrounding people with dementia'. Regarding the known-group validity, results showed that the group with a qualified chief care manager scored significantly higher than the group without one on Factors I (P = 0.013) and III (P = 0.026). Cronbach's alpha coefficient for the 18 items was 0.928. CONCLUSIONS The findings prove that the scale has acceptable reliability and validity, and can help care managers reflect on their practice. Future research is desirable to measure the validation of change in the scale.

Abstract
OBJECTIVES The COVID-19 outbreak severely affected long-term care (LTC) service provision. This study aimed to quantitatively evaluate its impact on the utilization of LTC services by older home-dwelling adults and identify its associated factors. DESIGN A retrospective repeated cross-sectional study. SETTING AND PARTICIPANTS Data from a nationwide LTC Insurance Comprehensive Database comprising monthly claims from January 2019 to September 2020. METHODS Interrupted time series analyses and segmented negative binomial regression were employed to examine changes in use for each of the 15 LTC services. Results of the analyses were synthesized using random effects meta-analysis in 3 service types (home visit, commuting, and short-stay services). RESULTS LTC service use declined in April 2020 when the state of emergency (SOE) was declared, followed by a gradual recovery in June after the SOE was lifted. There was a significant association between decline in LTC service use and SOE, whereas the association between LTC service use and the status of the infection spread was limited. Service type was associated with changes in service utilization, with a more precipitous decline in commuting and short-stay services than in home visiting services during the SOE. Service use by those with dementia was higher than that by those without dementia, particularly in commuting and short-stay services, partially canceling out the decline in service use that occurred during the SOE. CONCLUSIONS AND IMPLICATIONS There was a significant decline in LTC service utilization during the SOE. The decline varied depending on service types and the dementia severity of service users. These findings would help LTC professionals identify vulnerable groups and guide future plans geared toward effective infection prevention while alleviating unfavorable impacts by infection prevention measures. Future studies are required to examine the effects of the LTC service decline on older adults.

Abstract
BACKGROUND Level of care-need (LOC) is an indicator of elderly person's disability level and is officially used to determine the care services provided in Japan's long-term care insurance (LTCI) system. The 2018 Japan Floods, which struck western Japan in July 2018, were the country's second largest water disaster. This study determined the extent to which the disaster affected the LOC of victims and compared it with that of non-victims. METHODS This is a retrospective cohort study, based on the Japanese long-term care insurance claims from two months before (May 2018) to five months after the disaster (December 2018) in Hiroshima, Okayama, and Ehime prefectures, which were the most severely damaged areas in the country. A code indicating victim status, certified by a residential municipality, was used to distinguish between victims and non-victims. Those aged 64 years or younger, those who had the most severe LOC before the disaster, and those whose LOC increased even before the disaster were excluded. The primary endpoint was the augmentation of pre-disaster LOC after the disaster, which was evaluated using the survival time analysis. Age, gender, and type of care service were used as covariates. RESULTS Of the total 193,723 participants, 1,407 (0.7%) were certified disaster victims. Five months after the disaster, 135 (9.6%) of victims and 14,817 (7.7%) of non-victims experienced the rise of LOC. The victim group was significantly more likely to experience an augmentation of LOC than the non-victim group (adjusted hazard ratio 1.24; 95% confidence interval 1.06-1.45). CONCLUSIONS Older people who were affected by the disaster needed more care than before and the degree of care-need increase was substantially more than non-victims. The result suggests that natural disasters generate more demand for care services among the older people, and incur more resources and cost for society than before.

Abstract
Perceived discrimination and work impairment are commonly observed in COVID-19 survivors, but their relationship has not been well understood. We aimed to evaluate the role of discrimination in the development of psychological distress and work impairment in COVID-19 survivors. From April 2020 to November 2021, 309 patients were recruited at two designated COVID-19 hospitals in Japan. Participants completed a standardized questionnaire including COVID-19 sequelae, psychological distress, impairments in work performance and perceived discrimination. The majority of participants (62.5%) experienced one or more COVID-19 sequelae. Psychological distress was observed in 36.9% and work impairment in 37.9%. In multivariate logistic regression analyses, COVID-19 sequelae and discrimination were associated with both psychological distress and work impairment. Mediation analysis demonstrated that the direct effect of sequelae on work impairment was non-significant after accounting for psychological distress, suggesting that the effect of sequelae on work impairment was mainly mediated through psychological distress. These findings were replicated in a subgroup analysis limited to patients with mild COVID-19. We conclude that discrimination plays an important role in the development of psychological distress and work impairment, and that both discrimination and psychological distress should be targets of intervention in COVID-19 survivors.

Abstract
AIMS TMS-007, an SMTP family member, modulates plasminogen conformation and enhances plasminogen-fibrin binding, leading to promotion of endogenous fibrinolysis. Its anti-inflammatory action, mediated by soluble epoxide hydrolase inhibition, may contribute to its efficacy. Evidence suggests that TMS-007 can effectively treat experimental thrombotic and embolic strokes with a wide time window, while reducing haemorrhagic transformation. We aim to evaluate the safety, pharmacokinetics and pharmacodynamics of TMS-007 in healthy volunteers. METHODS This was a randomized, placebo-controlled, double blind, dose-escalation study, administered as a single intravenous infusion of TMS-007 in cohorts of healthy male Japanese subjects. Six cohorts were planned, but only five were completed. In each cohort (n = 8), individuals were randomized to receive one of five doses of TMS-007 (3, 15, 60, 180 or 360 mg; n = 6) or placebo (n = 2). RESULTS TMS-007 was generally well tolerated, and no serious adverse events were attributed to the drug. A linear dose-dependency was observed for plasma TMS-007 levels. No symptoms of bleeding were observed on brain MRI analysis, and no bleeding-related responses were found on laboratory testing. The plasma levels of the coagulation factor fibrinogen and the anti-fibrinolysis factor α2 -antiplasmin levels were unchanged after TMS-007 dosing. A slight increase in the plasma level of plasmin-α2 -antiplasmin complex, an index of plasmin formation, was observed in the TMS-007 group in cohort 2. CONCLUSIONS TMS-007 is generally well tolerated and exhibits favourable pharmacokinetic profiles that warrant further clinical development.

Abstract
PURPOSE Natural disaster has an impact on mental health. The 2018 Japan Floods, which took place in July 2018 were one of the largest water disasters in Japan's recorded history. We aimed to evaluate the change in the number of benzodiazepine prescriptions by physicians before and after the disaster. METHODS A retrospective cohort study based on the National Database of Health Insurance Claims was conducted in the flood-stricken areas between July 2017 and June 2019. The subjects were divided between victims and non-victims according to certification by local governments. Members of both groups were then categorized into three groups based on their pre-flood use of benzodiazepines: non-user, occasional user, and continuous user. Difference-in-differences (DID) analysis with a logistic regression model was conducted to estimate the effect of the disaster among victims by comparing the occurrence of benzodiazepine prescriptions before and after the disaster. RESULTS Of 5,000,129 people enrolled, 31,235 were victims. Among all participants, the mean prescription rate for benzodiazepines in victims before the disaster (11.3%) increased to 11.8% after the disaster, while that in non-victims (8.3%) decreased to 7.9%. The DID analysis revealed that benzodiazepine prescription among victims significantly increased immediately after the disaster (adjusted ratio of odds ratios (ROR) 1.07: 95% confidence interval 1.05-1.11), and the effect of the disaster persisted even 1 year after the disaster (adjusted ROR 1.2: 95% confidence interval 1.16-1.24). CONCLUSION The flood increased the number of benzodiazepines prescriptions among victims, and the effect persisted for at least 1 year.

Abstract
Aim The present study aimed to investigate the impact of the coronavirus disease 2019 (COVID‐19) pandemic on facility‐ and home‐dwelling people with dementia (PWD). Methods This observational study included two anonymous online survey questionnaires to explore the impact of the first wave of the COVID‐19 pandemic in Japan and the long‐term impact during the 2 years from the onset of the pandemic. The participants were medical and long‐term care facilities representatives for older people (945 facilities in the first survey, 686 in the second), and care managers (751 in the first survey, 241 in the second). A χ2‐test was carried out between the two surveys. Results For facility‐dwelling PWD, activities that stimulate cognitive and physical functioning increased significantly compared with the first wave of the pandemic (P < 0.05). Also, a decline in cognitive and walking functions and falls increased in the second survey compared with the first (P < 0.01). For home‐dwelling PWD, the broader impact of the pandemic on support for activities of daily living, social interaction and provision of medical care did not mitigate. The high prevalence of cognitive and physical functional decline in the first survey was similar in the second. Conclusions The prolonged COVID‐19 pandemic produced changes in the lives of home‐ and facility‐dwelling PWD, with widespread negative consequences for them. Our findings are useful to consider preventive supports to mitigate or avoid functional decline and symptom exacerbation in PWD due to changes in their living environment and the care they receive in the COVID‐19 era.

Abstract
Aim This study developed a risk scoring tool and examined its applicability using data from the Kihon Checklist cohort dataset for 19 months to predict the transition from no certification for long‐term care to long‐term care level 3 or above. Methods Data were collected from 26 357 functionally independent, community‐dwelling older adults in a Japanese city who answered the Checklist in 2014 and were followed for 19 months. Individuals certified for long‐term care during the follow‐up period were classified into three levels depending on their certification status: low, moderate, and high long‐term care levels. Relationships between the Kihon Checklist domains and high long‐term care levels were examined using the logistic regression model. A score chart predicting incidents of high long‐term care levels was created to facilitate its applicability. Results As of 2016, 971 participants were certified for long‐term care (3.7%), of which 168 (0.6%), 357 (1.4%), and 446 (1.7%) were certified as high, moderate, and low long‐term care levels, respectively. Variables associated with the certification of high long‐term care level included difficulties in activities of daily living, a decline in locomotor and cognitive function in the Kihon Checklist domains, and age. The score chart was created based on these variables and demonstrated excellent discriminatory ability, with an area under curve of 0.817 (95% confidence interval: 0.785–0.849). Conclusions The Kihon Checklist can predict the future development of a high degree of dependency. The score chart we developed can be easily implemented to identify older adults at high risk with reasonable accuracy. Geriatr Gerontol Int 2022; 22: 797–802.

Abstract
Background A prolonged COVID-19 pandemic could exacerbate the risk of infection and undesirable effects associated with infection control measures of older people with dementia (PWD), and the care burden of families. In this study, we examined the efficacy of care manager-led information provision and practical support for families of older PWD who need care, regarding appropriate infection prevention, prevention of deterioration of cognitive and physical functions, and preparedness in cases of infection spread or infection during the pandemic. Methods Fifty-three family members (aged ≥20 years) who were primary caregivers living with older PWD using public long-term care services were enrolled in an one-month randomized controlled trial. This duration was set based on behavior modification theory and with consideration of ethical issue that the most vulnerable people not benefiting from the intervention. The intervention group (IG) received care manager-led information provision and practical support, and the control group (CG) received usual care. Care burden (primary outcome) was measured using the Zarit Caregiver Burden Interview, and secondary outcomes were analyzed using Patient Health Questionnaire-9 (PHQ9), the Fear of COVID-19 Scale, and salivary α-amylase activity. Data were collected at baseline and after 1 month. Multiple regression analysis was conducted to examine the efficacy of the intervention. The participants evaluated the care managers’ support. Results The participants were randomly divided into IG (n = 27) and CG (n = 26) groups. After the intervention, compared with the CG, there was a decrease in PHQ-9 (β = −.202, p = 0.044) and α-amylase activity in saliva (β = −.265, p = 0.050) in IG. IG also showed an increased fear of COVID-19 after the intervention (β = .261, p = 0.003). With the care managers’ support, 57.2% of the participants felt secure in their daily lives and 53.1% agreed that they were able to practice infection prevention suitable for older PWD. Conclusions Our findings suggest that the care manager-led intervention may be useful for families of older PWD to enhance behavioral changes in preventing COVID-19 infection and improve their psychological outcomes in the COVID-19 era.

Abstract
Aim Social restrictions due to the coronavirus disease (COVID‐19) pandemic forced many long‐term care (LTC) service‐users to refrain from using services. We aimed to evaluate the degree of change in the use of LTC services. Methods We retrospectively analyzed data from the publicly distributed nationwide statistics summarizing the monthly number of public LTC insurance users in Japan between April 2018 and March 2021. The degree of decline was quantified as a ratio, where the ratio of a certain month to the reference month was divided by the ratio in the previous year. Results The use of LTC services started to decline in March 2020 and reached its largest decline in May 2020. Thereafter, it recovered but insufficiently, even as of late 2020. The degree of decline was particularly large for services provided in facilities for community‐dwelling elderly individuals [Ratio to the previous year = 0.717 (95% CI: 0.645–0.796) in short‐stay services, and Ratio = 0.876 (95% CI: 0.802–0.957) in outpatient services], but was non‐significant in other types of services, including those provided for elderly individuals living in nursing homes. Conclusions Community‐dwelling elderly individuals who had used outpatient or short‐stay services were especially affected by the COVID‐19 pandemic in 2020. This underlines the need for further investigation of the medium‐ or long‐term influence of the decline in service usage on the mental and physical health of the LTC service‐users and their caregivers.

Abstract
INTRODUCTION Among those caring for people with dementia (PwD) at home, more than 60% feel a caregiver burden (CB), and one in three are depressed. Reducing feelings of burden and depressive states in caregiving families will improve the living environment for PwD. However, very few studies have focused on effective methods and reducing feelings of burden and depressive states of caregivers. Thus, using data from a previous study, we aimed to determine the factors associated with perceived CB and depressive states experienced by caregivers for PwD with behavioral and psychological symptoms of dementia (BPSD) at home. METHODS We performed single regression analysis on 285 participants' data to determine the association between each item and the Zarit Caregiver Burden Interview and Center for Epidemiologic Studies-Depression Scale scores. We performed multiple regression analysis with variables considered in the single regression analysis as independent variables. RESULTS Severity of BPSD, caregivers' subjective health status (SHS), time of caregiving, and depressive states were related to CB, and caregivers' SHS and CB were related to depressive states. CONCLUSIONS Similar to previous studies, we identified an association between family caregivers' perceived CB and BPSD in PwD. Additionally, we found that caregivers' SHS is commonly associated with both perceived CB and depressive states. This is a new finding. Our results suggest that interventions focusing on family caregivers' health status can help not only to reduce family caregivers' CB and depressive states but also stabilize patients' symptoms and provide home-based care for a longer time.

Abstract
UNLABELLED Risk of fracture due to glucocorticoid-induced osteoporosis (GIO) can be reduced by anti-osteoporosis (OP) medications. The proportion of patients on long-term glucocorticoid therapy who received anti-OP medications according to the GIO management guidelines has increased in recent years, but is still suboptimal. INTRODUCTION Adherence of physicians to guidelines for glucocorticoid (GC)-induced osteoporosis (GIO) management is currently unclear. This study aimed to clarify the state of guideline adherence by physicians in Japan and identify factors associated with guideline adherence using a nationwide health insurance claims database (NDBJ). METHODS Patients aged ≥ 50 years who were prescribed GC for ≥ 90 days after 180 days without a GC prescription and who were followed up for osteoporosis (OP) management for the subsequent 360 days during the period spanning 2012-2018 were selected from the NDBJ. Guideline adherence was evaluated with the proportion of patients who received OP management as recommended by the Japanese guidelines. Information on previous vertebral and hip fractures, dementia, and polypharmacy was obtained. Factors associated with OP management were evaluated by logistic regression analysis. RESULTS A total of 512,296 patients were considered to be at high risk of fracture according to the guidelines. Proportions of patients receiving OP management (BMD testing or anti-OP medications) have increased in recent years. In 2017, 33.7% of men and 55.3% of women received OP management in the initial 90 days of GC therapy. Female sex, previous anti-OP medications, polypharmacy, and higher GC dose were significantly associated with receiving OP management, while dementia showed an inverse association. A prior history of hip fracture, a strong risk factor for future fracture, was not significantly associated with receiving OP management. CONCLUSIONS Although guideline adherence by physicians has increased in recent years, it remains suboptimal. Further efforts to improve guideline adherence are necessary. TRIAL REGISTRATION NUMBER The present study is not registered.

Abstract
BACKGROUND Most older people with disabilities or illnesses continue to use long-term care (LTC) services for the rest of their lives. However, disasters can cause a discontinuation of LTC services, which usually means tragic outcomes of affected persons. In view of the recent progression of population aging and the increase in natural disasters, this study focuses on the impact of disasters on older people's discontinuation of LTC services, and those more risk of such discontinuation than others. However, current evidence is scarce. METHODS We conducted a retrospective cohort study with 259,081 subjects, 2,762 of whom had been affected by disaster and 256,319 who had not been affected during the 2018 Japan Floods. The sample in the three most disaster-affected prefectures was drawn from the Long-term Care Insurance Comprehensive Database and included older people certified with care-need level. The observation period was two months before the disaster and five months after it. We calculated the hazard ratio (HR) of municipality-certified subjects affected by the disaster versus those who were not. Subgroup analyses were conducted for categories of individual-, facility- and region-associated factors. RESULTS Affected persons were twice as likely to discontinue LTC services than those who were not affected (adjusted HR, 2.06 95% CI, 1.91-2.23). 34% of affected persons whose facilities were closed discontinued their LTC services at five months after the disaster. A subgroup analysis showed that the risk of discontinuing LTC services for affected persons compared to those who were not affected in the relatively younger subgroup (age < 80: adjusted HR, 2.55; 95% CI, 2.20-2.96 vs. age ≥ 80 : 1.91; 1.75-2.10), and the subgroup requiring a lower level of care (low: 3.16; 2.74-3.66 vs. high: 1.71; 1.50-1.96) were more likely to discontinue than the older and higher care level subgroups. CONCLUSIONS A natural disaster has a significant effect on the older people's discontinuation of LTC services. The discontinuations are supposedly caused by affected persons' death, hospitalization, forced relocation of individuals, or the service provider's incapacity. Accordingly, it is important to recognize the risk of disasters and take measures to avoid discontinuation to protect older persons' quality of life.

Abstract
BACKGROUND Climate change has increased the frequency and severity of torrential rains and floods around the world. Estimating the costs of these disasters is one of the five global research priorities identified by WHO. The 2018 Japan Floods hit western Japan causing extensive destruction and many deaths, especially among vulnerable elderly. Such affected elderly would need long-term care due to the various health problems caused by the disaster. A Long-Term Care Insurance (LTCI) system provides care services in Japan. The aim of this study was to evaluate the effect of the 2018 Japan Floods on LTCI costs and service utilization. METHODS The participants of this retrospective cohort study were all verified persons utilizing LTCI services in Hiroshima, Okayama and Ehime prefectures. The observation period was from 2 months before to 6 months after the disaster. We used Generalized Estimating Equations (GEEs) to examine the association between disaster status (victims or non-victims) and the monthly total costs of LTCI service (with gamma-distribution/log-link) by residential environment (home or facility). Among home residents, we also examined each service utilization (home-based service, short-stay service and facility service), using the GEEs. After the GEEs, we estimated Average Marginal Effects (AME) over all observation periods by months as the attributable disaster effect. RESULTS The total number of participants was 279,578. There were 3024 flood victims. The disaster was associated with significantly higher total costs. The AME for home residents at 2 months after was $214 (Standard Error (SE): 12, p < 0.001), which was the highest through the observation period. Among facility residents, the AME immediately after the disaster increased by up to $850 (SE: 29, p < 0.001). The service utilization among home residents showed a different trend for each service. The AME of home-based services decreased by up to - 15.2% (SE:1.3, p < 0.001). The AME for short-stay service increased by up to 8.2% (SE: 0.9, p < 0.001) and the AME for facility service increased by up to 7.4% (SE: 0.7, p < 0.001), respectively. CONCLUSIONS The 2018 Japan Floods caused an increase in LTCI costs and the utilization of short-stay and facility services, and a decrease in utilization of home-based services.

Abstract
Background Little is known about the actual impact of COVID-19 on caregivers of older people with dementia and resultant collaborations among them to provide continued person-centered care while undertaking infection control measures. In this study, we explored the impact of providing dementia care during COVID-19 on caregivers involved in dementia care. Methods This is an exploratory qualitative case study. The participants were family members living with older people with dementia, care managers, and the medical and long-term care facility staff. Data were collected from 46 caregivers via face-to-face and semi-structured interviews and analyzed using thematic analysis. Results The interviews identified 22 themes related to the impact of COVID-19 on different positions of the caregivers involved in dementia care and their collaboration, and we categorized them into six categories. The core themes were “re-acknowledgement of care priorities” and “rebuilding of relationships.” When caregivers’ perceptions were aligned in the decision-making processes regarding care priorities, “reaffirmation of trust” and “strengthening of intimate relationships” emerged as positive changes in their relationships. Furthermore, the differences in the ability of each caregiver to access and select correct and appropriate information about COVID-19, and the extent of infection spread in the region were related to “anxiety during COVID-19 pandemic” and caused a “gap in perception” regarding infection control. Conclusions The present study clarified that the process of aligning the perceptions of caregivers to the objectives and priorities of care for older people with dementia during COVID-19 pandemic strengthened the relationships among caregivers. The findings of this study are useful for caregivers involved in person-centered dementia care.

Abstract
Only one case of melanoma arising from melanin-producing medullary thyroid carcinoma (MTC) has been reported previously. In the present study, a second such case was reported and compared with the previous one. The patient was an 86-year-old male who presented with a right anterior neck mass. Ultrasound revealed a nodule measuring 49x48x40 mm in the right lobe of the thyroid. The levels of serum calcitonin (2,298 pg/ml) and carcinoembryonic antigen (CEA; 27.0 ng/ml) were markedly elevated. Aspiration cytology revealed suspected malignant anaplastic thyroid carcinoma and total thyroidectomy without neck nodal dissection was performed. On gross observation, the nodule was well encapsulated, soft, solid and black. Light microscopy indicated that the nodule was composed mainly of large, occasionally huge, pleomorphic cells with a solid or alveolar growth pattern. On immunohistochemistry, these cells were positive for melan-A and S-100 protein, and negative for thyroid transcription factor 1, calcitonin, chromogranin A and CEA. In the subcapsular area, melanin-producing MTC was intimately intermingled with the pleomorphic cells. No primary site of the melanoma was detectable in other organs. At three years after surgery, the patient died due to metastasis of the melanoma to the brain. The previously reported case had no detectable recurrence or distant metastasis up to 11 years after surgery. In comparison with that case, the present case had a similar morphology but the outcome was poorer. Thus, the prognosis of melanoma that transforms from MTC appears to remain uncertain.

Abstract
Aim This study aimed to explore the perceptions of dementia experts on support for people with dementia (PWD) and their families, considering PWD's vulnerability regarding COVID‐19 prevention. Methods A collaborative qualitative study was conducted, involving Hiroshima University, the Japan Geriatrics Society, the Japan Society for Dementia Research, and the Japanese Psychogeriatric Society. An anonymous, self‐reported questionnaire survey was sent to dementia experts from 456 medical centers for dementia in Japan. The responses were categorized in a qualitative inductive manner. Results A total of 214 experts from 119 centers responded (facility recovery rate: 26.1%). Four core themes emerged from the data analysis. Of these themes, three were related to support for infection prevention and related issues and response to infection: (i) support for continuation of daily life while preventing infection; (ii) support to mitigate the unfavorable effects of infection prevention measures; and (iii) decision‐making support and treatment for infected PWD. The remaining theme, (iv) community building for PWD living together, was extracted as a basis for facilitating themes (i) to (iii). Furthermore, in each theme, the roles of medical and long‐term care facilities, administration, and the need for community collaboration were identified. Conclusions Dementia experts strongly felt the need not only for short‐term support to prevent the spread of infection to PWD and their families during the pandemic, but also for long‐term support to enable them to maintain their daily lives and mitigate the impact of infection prevention measures.

Abstract
Abstract
Background
Impella has been increasingly used in patients with cardiogenic shock (CGS). Target values for clinical indices for appropriate management of Impella have not yet been established.
Purpose
We aimed to elucidate the association between heat rate (HR) during Impella treatment in patients with CGS and clinical outcomes.
Methods and results
We retrospectively evaluated 62 patients (68±14 years; male 77%) with CGS receiving temporary circulatory support with the Impella between February 1, 2019, and February 31, 2021. The primary end point was 30-day mortality. Clinical characteristics, laboratory and hemodynamic markers at implantation of Impella (baseline), 12, 24 hr after implantation, and removal of Impella were assessed. There were 28 patients with concomitant use of extracorporeal membrane oxygenation (ECMO). Treatment periods using Impella were 8±6 days. After excluding 11 patients who died during Impella support, the relationship between clinical indicators at each time points and 30-day mortality was evaluated. There were 22 patients (43%) with 30-day mortality. Factors associated with 30-day mortality were: female, ECMO, higher 24-hr lactate level, lower 24-hr cardiac power output, and higher HR at removal. Lower HR of ≤81 bpm at removal was found to most accurately predict lower 30-day mortality (Figure 1). Higher increases in dose of beta-blockers during Impella support and lower absolute doses of norepinephrine at removal were correlated with decreases in HR during Impella support.
Conclusions
In patients with CGS treated with Impella, lower HR at removal was associated with lower incidence of 30-day mortality. Lowering HR during Impella treatment was recognized as a simple indicator for favorable clinical outcomes in patients with CGS. It was suggested that chronotropic interventions during Impella treatment may be novel therapeutic options in patients with CGS.

Abstract
Background:Connective tissue disease (CTD) associated pulmonary arterial hypertension (PAH) is considered to be an indication for immunosuppressive therapy (IT) except scleroderma associated PAH. However, the response rate defined by improvement of WHO functional class and hemodynamic parameters is reported to be around 50% [1]. Since CTDs are systemic diseases, it may be difficult to evaluate the efficacy of IT by subjective symptoms. Although there are previous studies reporting that the combined use of IT and pulmonary vasodilators significantly improved hemodynamics [2], response to IT without titration of pulmonary vasodilators remains to be elucidated.Objectives:To examine whether IT is effective for CTD-PAH.Methods:We retrospectively examined the medical records of consecutive 13 patients with CTD-PAH (female 13, mean age 47 ± 15 years) treated with methylprednisolone (1 mg/kg/day, oral) and intravenous bolus cyclophosphamide (IVCY) (500 mg/m2) every four weeks for six times. Patient characteristics are described in Table 1. Right heart catheterization (RHC) was done at prior to IT, before adding PAH specific agents, and at the fifth or sixth course of IVCY. In treated cases, the previous vasodilators remained unchanged during the first term of IT.Results:At the first follow up RHC, decrease of mean pulmonary arterial pressure over 5 mmHg was observed in all patients, and decrease of pulmonary vascular resistance (PVR) was observed in twelve out of 13 patients (Figure 1). Over 20% of PVR reduction was observed more in the patients of pulmonary vasodilator naïve and started IT within one year from symptoms than others (6/7 vs 1/6, p=0.03). Although six-minutes walk distance (6MWD) tended to be prolonged between first and second RHC (298 ± 70 m vs 382 ± 81 m; p=0.054; n = 9), 6MWD was shortened in some cases with good hemodynamic improvement (2/5). All patients were prescribed oral PAH specific agents finally, but no one needed parenteral prostanoids. Two patients (15%) died during maintenance therapy for causes other than PAH. Three-year and five-year survival rates were 91.7% and 81.5%, respectively.Conclusion:IT without titration of pulmonary vasodilators significantly improved hemodynamic parameters despite of less improvement in 6MWD in CTD-PAH patients. Considering that CTDs itself might affect the exercise tolerance regardless of PAH, these hemodynamic changes may contribute to better prognosis and IT might be considered especially for patients early in clinical courses and treatment naïve.References:[1]Jais X, Launay D, Yaici A, et al.

Abstract
Background:Hepatocyte growth factor (HGF) binds to the receptor tyrosine kinase c-Met and is a multifunctional cytokine that promotes processes such as cell proliferation, survival, differentiation, migration and angiogenesis [1]. We previously reported that HGF is produced by inflammation in the RA synovium, and activates monocyte migration to the synovium and promotes bone destruction through its own chemotactic effect and enhanced chemokine production in the synovium [2].Objectives:Therefore, we next aimed to determine the role of HGF in RA angiogenesis.Methods:The expression of HGF / c-Met in the serum and synovial tissues (STs) of RA patients and controls and human umbilical vein endothelial cells (HUVECs) was evaluated by ELISA and immunostaining. The effect of HGF/c-Met signaling on the promotion of CXCL16 production from HUVECs and RA fibroblast-like synoviocytes (FLSs) was determined by ELISA. To examine the role of HGF in angiogenesis, we performed in vitro Matrigel assays using HUVECs treated with HGF.Results:HGF in serum in treatment-naive RA patients was significantly higher than that in controls and HGF in serum in treatment-resistant RA showed a significant positive correlation with CXCL16. c-Met were expressed on vascular endothelial cells of RA STs and HUVECs. Stimulation of HUVECs with HGF dose-dependently increased CXCL16 production. c-Met signal inhibition by SU11274 suppressed TNF-α stimulation-enhanced CXCL16 production by RA FLSs in a dose-dependent manner. Furthermore, HGF induced HUVEC tube formation by 1.8-fold.Conclusion:HGF is produced by inflammation in the RA synovium, and activates angiogenesis through its own potent angiogenic effect and enhanced production of CXCL16 in the synovium. These results indicate that a strategy targeting c-Met signalling may be important for resolving treatment-resistant RA.References:[1]Nakamura T, Nishizawa T, Hagiya M, et al.

Abstract
Background:Eosinophilic fasciitis (EF) is a rare disease that causes inflammation and fibrosis mainly in the fascia of the extremities with eosinophilia. It has been reported that the hypertrophied fascia in EF shows inflammatory cell infiltration by the lymphocytes and eosinophils and increased expression of fibrosis-related cytokines genes in fibroblast [1]. However, its pathophysiology in the fascia remains unresolved.Objectives:Therefore, we focused on fascial fibroblasts and aimed to determine the role of interleukin-4 (IL-4) in eosinophil and helper T cell infiltration and fibrosis in fascial fibroblast in EF.Methods:Fascial fibroblasts were obtained from fascia biopsy of a patient with EF, and were stimulated with pre- and post-treatment serum of a patient with EF and healthy control, followed by microarray to analyze gene expression. Fascial fibroblasts were stimulated with IL-4 10 ng/mL, and gene expression of IL-4 receptor and CCR3 ligands, CCL7 and CCL11 were measured by qPCR. Transforming growth factor (TGF) -β and periostin in the pre- and post-treatment serum of a patient with EF and conditioned medium of fascial fibroblasts stimulated with IL-4 were measured by ELISA. To examine the role of IL-4 in proliferation, we performed in proliferation assays using fascial fibroblasts treated with IL-4. CCR3-positive T cells in the fascial tissue of EF, dermatomyositis, and polymyositis patients were evaluated by immunostaining.Results:By microarray analysis, CCL7 and CCL11 expression of fascial fibroblasts stimulated with pre-treatment EF serum was higher than that in post-treatment EF serum and control serum. CCL7 and CCL11 mRNA in IL-4 stimulated facial fibroblasts were increased by 5.1-fold and 7.3-fold, respectively. TGF-β and periostin in IL-4 stimulated facial fibroblast conditioned medium were also increased. In addition, TGF-β and periostin in EF serum were gradually decreased by treatment for 4 and 10 weeks, compared to before treatment. Finally, fascial fibroblast proliferation was significantly increased by stimulation with IL-4. Furthermore, infiltration of CCR3-positive T cells was specific to the fascial tissue of EF.Conclusion:In EF, IL-4 enhances the production of CCR3 ligands, TGF-β, and periostin from fascial fibroblasts. As a result, it promotes the migration of eosinophils and CCR3-positive T helper cells to the fascia and fibrosis. These results suggest that inhibition of IL-4 pathway could be a novel strategy for eosinophilic fasciitis.References:[1]Igarashi A, Nashiro K, Kikuchi K, et al.

Abstract
OBJECTIVES To evaluate the prescription and discontinuation of psychotropic drugs (PD) and drugs with anticholinergic properties (DAP) in residents with dementia admitted to Roken, a major type of long-term care facility in Japan. DESIGN Cohort study. SETTING A nationwide questionnaire survey across 3598 Roken in Japan in 2015 (up to five randomly selected residents per facility). PARTICIPANTS This study included 1201 residents from 343 Roken (response rate: 10%). We determined the presence and severity of dementia using a nationally standardised measure. PRIMARY AND SECONDARY OUTCOME MEASURES Prescriptions of PD and DAP at admission and 2 months after admission were evaluated. Multivariable logistic regression was used to evaluate the associations of residents' baseline characteristics with prescriptions or discontinuation. RESULTS Prescription rates decreased for antidementia drugs (19.4% to 13.0%), hypnotics (25.1% to 22.6%) and anxiolytics (12.3% to 10.7%), whereas those for other PD, such as antipsychotics (13.2% to 13.6%), antidepressants (7.4% to 6.7%), antiepileptic drugs (7.1% to 7.8%) and DAP (35.2% to 36.6%) did not statistically significantly decrease. Some factors were associated with the prescriptions, for example, for antipsychotics, older age (≥85 years) (adjusted OR (aOR), 0.60; 95% CI 0.43 to 0.85) and being bedridden (aOR 0.67; 95% CI 0.47 to 0.97) were associated with a lower use of antipsychotics, whereas severe dementia was associated with a higher use of antipsychotics (aOR 3.26; 95% CI 2.26 to 4.70). At an individual level, a quarter of residents prescribed PD or DAP at admission had discontinued at least one PD or DAP, respectively, 2 months after admission. Antidementia drug use in severe dementia (aOR 1.86; 95% CI 1.04 to 3.31) and PD use in older age (aOR 1.61; 95% CI 1.00 to 2.60; in residents with disabling dementia) were associated with discontinuation. CONCLUSIONS There is possible scope for deprescribing PD and DAP in Roken residents with dementia to mitigate the risks of adverse events.

Abstract
AIMS The aim of this study was to obtain cold-adapted denitrifying fungi that could be used for bioaugmentation in woodchip bioreactors to remove nitrate from agricultural subsurface drainage water. METHODS AND RESULTS We isolated a total of 91 nitrate-reducing fungal strains belonging to Ascomycota and Mucoromycota from agricultural soil and a woodchip bioreactor under relatively cold conditions (5 and 15°C). When these strains were incubated with 15 N-labelled nitrate, 29 N2 was frequently produced, suggesting the occurrence of co-denitrification (microbially mediated nitrosation). Two strains also produced 30 N2 , indicating their ability to reduce N2 O. Of the 91 nitrate-reducing fungal strains, fungal nitrite reductase gene (nirK) and cytochrome P450 nitric oxide reductase gene (p450nor) were detected by PCR in 34 (37%) and 11 (12%) strains, respectively. Eight strains possessed both nirK and p450nor, further verifying their denitrification capability. In addition, most strains degraded cellulose under denitrification condition. CONCLUSIONS Diverse nitrate-reducing fungi were isolated from soil and a woodchip bioreactor. These fungi reduced nitrate to gaseous N forms at relatively low temperatures. These cold-adapted, cellulose-degrading and nitrate-reducing fungi could support themselves and other denitrifiers in woodchip bioreactors. SIGNIFICANCE AND IMPACT OF THE STUDY The cold-adapted, cellulose-degrading and nitrate-reducing fungi isolated in this study could be useful to enhance nitrate removal in woodchip bioreactors under low-temperature conditions.

Abstract
Abstract
Background
Re-worsening left ventricular ejection fraction (LVEF) after initial recovery occurs in some patients with dilated cardiomyopathy (DCM). However, prevalence and predictors of re-worsening LVEF in longitudinal follow-up are unclear. Late gadolinium enhancement of cardiovascular magnetic resonance (LGE-CMR) can evaluate the damage of myocardial tissue.
Purpose
This study sought to evaluate the clinical parameters including LGE-CMR to predict re-worsening LVEF in patients with recent-onset DCM.
Methods
We included patients with recent-onset DCM who had an LVEF <45% and underwent LGE-CMR at diagnosis. We performed yearly echocardiographc follow-up [median 6 [4–8.3] years]. Initial LVEF recovery defined as patients increased in >5% LVEF from baseline and had an LVEF≥45% after medical therapy. Patients were divided into three groups: (1) Improved: defined as those with sustained LVEF ≥45% after initial LVEF recovery; (2) Re-worse: those with decreased >5% and had an LVEF <45% after initial LVEF recovery. and (3) Not-improved: those with no initial LVEF recovery during follow-up. To evaluate the prognostic factors for Re-worsening LVEF after initial LVEF recovery, multivariate logistic regression analysis performed between the Improved group and the Re-worse group. Cardiac events defined as hospitalization due to heart failure and sudden death.
Results
Of 138 patents, 82 patients (59%) were the Improved group, 42 patients (30%) were the Re-worse group, and 14 (10%) were the Not-improved group. Loess curves of long-term LVEF trajectories showed that LVEF in the Re-worse group increased first 2 years and declined slowly thereafter (Fig. 1A). Re-worsening LVEF occurred 4.5±2.2 years after initial LVEF recovery. Multivariate logistic regression analysis demonstrated that LGE area at baseline (Odds ratio: 1.09, 95% confidence interval (CI) 1.02–1.18, p=0.014) and Log brain natriuretic peptide (BNP) at initial LVEF recovery (Odds ratio: 1.53, 95% confidence interval (CI) 1.01–2.31, p=0.042) were independent predictors for Re-worsening LVEF. Kaplan Meier analysis demonstrated that the risk of cardiac events in the Re-worse group was significantly higher (hazard ratio: 3.93, 95% CI 1.49–10.36, p=0.006) than in the Improved group and lower risk than in the Not-improved group (hazard ratio: 0.28, 95% CI 0.12–0.62, p=0.002) (Fig. 1B).
Conclusion
Re-worsening LVEF occurred in 30% of patients in patients with recent-onset DCM. LGE area and BNP at initial LVEF recovery were independently associated with re-worsening LVEF after initial LVEF recovery.

Abstract
Aim The perceived age of older adults, as measured by their facial appearance, has been shown to be a robust biomarker of aging predictive of survival, telomere length and DNA methylation, and reportedly correlates with carotid atherosclerosis and bone status. This study aimed to determine whether metrics of dementia, including general cognition, vitality, depressive state and self‐supportability, have stronger correlations with perceived age than with chronological age. Methods This study included 124 patients who were admitted to the Department of Geriatric Medicine, The University of Tokyo Hospital, on account of being suspected of cognitive decline. The Mini‐Mental State Examination, Vitality Index, Geriatric Depression Scale‐15, instrumental activities of daily living and Barthel Index were carried out. Five experienced geriatricians and five experienced clinical psychologists determined the perceived age of participants based on photographs. Results The average values of the 10 raters showed excellent reliability (intraclass correlation coefficient (3, 10) = 0.941). Steiger's test revealed that perceived age showed a significantly better correlation with the Mini‐Mental State Examination (female) and Vitality Index (total, female) than did chronological age, but not with Geriatric Depression Scale‐15, instrumental activities of daily living or the Barthel Index. Conclusions Perceived age was shown to be a reliable biomarker for cognitive assessment. Geriatr Gerontol Int 2020; 20: 779–784.

Abstract
Background:Hepatocyte growth factor (HGF), originally discovered as a mitogen of hepatocytes, binds to receptor-tyrosine kinase c-Met and has been shown to be a multi-functional cytokine that promotes processes such as cell proliferation, survival, differentiation, migration, and angiogenesis1. Since HGF/c-Met signaling also leads to tumorigenesis and cancer invasion, that has recently attracted attention as a target for anticancer agents2. However, in reports of rheumatoid arthritis (RA), though anti-inflammatory and antiangiogenic mechanisms related to HGF/c-Met signal inhibition have been reported, the role of HGF in RA bone destruction through monocyte migration remains unclear3.Objectives:To determine the expression of HGF in RA biological fluids, the role it plays in monocyte migration and the therapeutic effect of a savolitinib, a specific c-Met inhibitor, in arthritis model mice.Methods:HGF/c-Met expression in serum, synovial fluid (SF), and synovial tissues (STs) obtained from RA patients and control subjects, as well as RA fibroblast-like synoviocytes (FLSs) was evaluated by ELISA and immunostaining. To determine the function of HGF in RA SFs, we preincubated RA SFs with a neutralizing anti-HGF antibody and measured the ability of these SFs to induce the human acute monocytic leukemia cell line (THP-1) chemotaxis. Additionally, examinations of SKG mice treated with savolitinib (2.5 mg/kg/day) for 4 weeks were conducted.Results:HGF level in serum from RA patients was significantly higher as compared to the controls (930 ± 97 vs. 476 ± 97 pg/mL, p <0.01) and decreased by drug treatment for 24 weeks (1147 ± 284 vs. 539 ± 160 pg/mL, p <0.05). Additionally, HGF level in SF from RA patients was higher as compared to SF from osteoarthritis patients (1632 ± 366 vs. 566 ± 140 pg/mL, p <0.05). HGF and c-Met expressions were also noted in RA STs. Stimulation of RA-FLS with TNF-α increased HGF/c-Met expression in a concentration-dependent manner, and c-Met signal inhibition by SU11274 suppressed production of fractalkine/CX3CL1, CXCL16, and MIP-1α/CCL3 (mean 50%, 56%, 90%, respectively). When HGF was removed by immunoprecipitation, migration of THP-1 in RA-SF was suppressed (mean 23%). In SKG mice, savolitinib significantly suppressed ankle bone damage on µCT, with an associated reduction in number of tartrate-resistant acid phosphatase-positive osteoclasts.Conclusion:HGF is produced by inflammation in synovium associated with RA, and then activates monocyte migration to synovium tissue and promotes bone destruction through its own chemotactic effect as well as enhanced chemokine production. These results indicate that a strategy that targets c-Met signaling may be important for resolving bone destruction in RA.References:[1] Nakamura T, Nishizawa T, Hagiya M, Seki T, Shimonishi M, Sugimura A, Tashiro K, Shimizu S.

Abstract
OBJECTIVES No established approaches exist for the pharmacological management of cardiovascular diseases (CVDs) in residents of long-term care facilities (LTCFs). This study aimed to evaluate the use of drugs for CVD prevention and treatment (CVD-related drugs) in a major type of LTCF in Japan. METHODS This study included 1318 randomly selected residents at 349 intermediate care facilities for older adults (called Roken). Prescriptions were investigated at admission and two months after admission according to therapeutic categories. Logistic regression was used to identify residents' characteristics that were associated with prescriptions of CVD-related drugs. RESULTS Prescriptions of all types of drugs and CVD-related drugs decreased in 36 % and 16 % of residents, respectively. Half of the residents received antihypertensives, a quarter received antiplatelets and diuretics, whereas one-tenth received antidiabetics, oral anticoagulants, and lipid-modifying drugs. The prevalence of most of individual drug categories were similar among residents with different physical or cognitive function, except for fewer antihypertensive and lipid-modifying drugs in those with severe cognitive disability. Adjusted analyses for prescriptions at two months after admission revealed that bedridden residents were more likely to be prescribed diuretics but less likely to be prescribed antihypertensives, antiplatelets, or lipid-modifying drugs. Residents with severe cognitive disability were less likely to be prescribed antihypertensives or lipid-modifying drugs. A known history of cardiovascular events was associated with greater use of CVD-related drugs. CONCLUSION CVD-related drugs were commonly prescribed for Roken residents, including those with low physical and cognitive functions. Deprescribing may contribute to the optimization of pharmacotherapy in LTCF residents.

Abstract
UNLABELLED We assessed whether a bone resorption marker, measured early in the menopause transition (MT), is associated with change in femoral neck size and strength during the MT. Higher levels of bone resorption were associated with slower increases in femoral neck size and faster decreases in femoral neck strength. PURPOSE Composite indices of the femoral neck's ability to withstand compressive (compression strength index, CSI) and impact (impact strength index, ISI) forces integrate DXA-derived femoral neck width (FNW), bone mineral density (BMD), and body size. During the menopause transition (MT), FNW increases, and CSI and ISI decrease. This proof-of-concept study assessed whether a bone resorption marker, measured early in the MT, is associated with rates of change in FNW, CSI and ISI during the MT. METHODS We used previously collected bone resorption marker (urine collagen type I N-telopeptide [U-NTX]) and femoral neck strength data from 696 participants from the Study of Women's Health Across the Nation (SWAN), a longitudinal study of the MT in a multi-ethnic cohort of community-dwelling women. RESULTS Adjusted for MT stage (pre- vs. early perimenopause), age, body mass index (BMI), bone resorption marker collection time, and study site in multivariable linear regression, bone resorption in pre- and early perimenopause was not associated with transmenopausal decline rate in femoral neck BMD. However, each standard deviation (SD) increase in bone resorption level was associated with 0.2% per year slower increase in FNW (p = 0.03), and 0.3% per year faster declines in CSI (p = 0.02) and ISI (p = 0.01). When restricted to women in early perimenopause, the associations of bone resorption with change in FNW, CSI, and ISI were similar to those in the full sample. CONCLUSIONS Measuring a bone resorption marker in pre- and early perimenopause may identify women who will experience the greatest loss in bone strength during the MT.
