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

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity and quantum anomalous Hall effects. Recently, a charge density wave (CDW) has been observed in the kagome antiferromagnet FeGe, indicative of possible intertwining physics. An outstanding question is that whether magnetic correlation is fundamental for the spontaneous spatial symmetry breaking orders. Here, utilizing elastic and high-resolution inelastic x-ray scattering, we observe a c-axis superlattice vector that coexists with the 2[Formula: see text]2[Formula: see text]1 CDW vectors in the kagome plane. Most interestingly, between the magnetic and CDW transition temperatures, the phonon dynamical structure factor shows a giant phonon-energy hardening and a substantial phonon linewidth broadening near the c-axis wavevectors, both signaling the spin-phonon coupling. By first principles and model calculations, we show that both the static spin polarization and dynamic spin excitations intertwine with the phonon to drive the spatial symmetry breaking in FeGe.

Abstract
This study aims to estimate the potential economic benefits of healthy ageing by obtaining estimates of the economic losses generated by functional limitations among middle-aged and older people. Utilising two data sources retrieved from nationally representative samples of the Japanese people, we analysed the association between functional limitation and economic indicators, including labour market outcomes, savings, investment, consumption, and unpaid activities among individuals aged ≥ 60. Using the estimated parameters from our micro-econometric analyses and the official statistics by the Japanese government and a previous study, we calculated the financial costs that can be averted if healthy ageing is achieved as foregone wages and formal medical/long-term care costs incurred by functional limitations. Our micro-econometric analyses found that functional limitation was associated with a 3% point increase in retirement probability, with a stronger association among those aged 60-69. Moreover, functional limitation was linked with higher total health spending and less active involvement in domestic work. Foregone wages generated by functional limitation were estimated to be approximately USD 266.4 million, driven mainly by individuals in their 60s. Long-term care costs, rather than medical care costs, for older people aged ≥ 85 accounted for most of the additional costs, indicating that the estimated medical and long-term costs generated by functional limitations were approximately USD 72.7 billion. Health interventions can yield economic benefits by preventing exits from the labour market due to health issues and reducing medical and long-term care costs.

Abstract
As longevity occurs, people encounter various risks associated with ageing, including economic uncertainty and health issues. Therefore, in addition to extending healthy life expectancy, it is crucial to create an environment where older people can live better even when their intrinsic capacity declines. Additionally, integrated and comprehensive care for older adults is needed to maintain their functional ability and well-being at higher levels. This review provides an overview of the systems and initiatives in Japan, a forerunner of population ageing that supports the quality of life of older people and summarises their remaining challenges. In Japan, with support for access to necessary care available from social welfare councils and community comprehensive support centres, various health and welfare services are provided to respond to the needs of people with different levels of intrinsic capacity, including medical care, preventive care, long-term care, adult guardianship systems, pensions, and social assistance. Nevertheless, there are challenges for the systems, including the gap between life and healthy life expectancy, moderate accumulation and decumulation of retirement assets, lack of human and financial resources for care, and user-unfriendliness and non-covered needs of the current system. Therefore, integrated and comprehensive care beyond health and long-term care is needed to maintain the well-being of older adults, even with their intrinsic capacity declining.

Abstract
OBJECTIVES Previous research has suggested cross-national differences in the association between living alone and well-being among older adults. This study examined whether the association varied across social contexts within the country, Japan, in terms of varying degree of urbanization and differential time periods. METHODS Data were obtained from a nine-wave nationwide longitudinal survey with a probability sample of Japanese adults aged 60 years and over. Respondents belonged to one of the three periods (around 1990, 2000, and 2015) according to the year they commenced participation. As many as 4,655 individuals from 575 municipalities provided 9,016 observation sets of two consecutive waves (t - 1 and t). Within a framework of the Hierarchical Generalized Linear Model, depressive symptoms at t were predicted based on changes in living arrangements from t - 1 to t and their cross-level interactions with gender, level of urbanization, and time period, controlling for various covariates at t - 1. RESULTS In general, older adults living alone continuously as well as those who started living alone between the waves showed more depressive symptoms than those coresiding with someone continuously. However, this tendency was more prominent among rural residents than their urban counterparts, especially for men. Moreover, the effect of continuously living alone on depressive symptoms became smaller in Period 2015 than that in Period 1990, because of the increase in depressiveness in coresident older adults. DISCUSSION Our findings indicate that living alone has a differential effect on older adults' well-being depending on the social context where residents' preferences for living arrangements and availability of formal services could vary.

Abstract
OBJECTIVES While the health effects of retirement have been well studied, existing findings remain inconclusive, and the mechanisms underlying the linkage between retirement and health are unclear. Thus, this study aimed to evaluate the effects of retirement on health and its potential mediators. METHODS Using a national household survey conducted annually from 2004 to 2019 in Japan (the Japan Household Panel Survey), we evaluated the effects of retirement among Japanese men aged 50 or older on their health, in addition to other outcomes that could be attributed to health changes associated with retirement (i.e., health behaviors, psychological well-being, time use for unpaid activities, and leisure activities). As outcomes are not measured every year, we analyzed 5,794-10,682 person-year observations for 975-1,469 unique individuals. To address the potential endogeneity of retirement, we adopted an instrumental variable fixed-effects approach based on policy changes in eligibility ages for employee pensions. RESULTS We found that retirement improved psychological well-being, exercise habits, and time spent on unpaid work. The psychological benefits of retirement were no longer observed for longer durations after retirement, whereas healthy habits and unpaid activities continued. Moreover, health-related improvements after retirement occurred mostly in the higher-income group. DISCUSSION Enhancement in personal quality of life owing to increased leisure time and stress reduction from work in addition to lifestyle changes may be key to understanding the health benefits of retirement. Considering the mechanisms behind retirement-health relationships and potential heterogeneous effects is essential for healthy postretirement lives when increasing the retirement age.

Abstract
The two important elements of universal health coverage—(1) enabling everyone to access the necessary health services and (2) providing financial protection from catastrophic health spending—are vital for not only healthcare but also long-term care in the context of population ageing. In this review, we provide an overview of the public long-term care system in Japan to help other countries that are experiencing (or are expected to experience) problems associated with population ageing. Japan’s approach to long-term care may not be universally generalisable, given the differences in population/geographical sizes, socioeconomic development, population ageing, and cultures across countries. However, the challenges faced by older people may be common. Japan’s long-term care system has several challenges, including financing, labour force shortages, support for people with dementia, an integrated continuum of healthcare and long-term care, and utilising services outside the purview of insurance coverage. We have provided the government’s actions and potential directions to address these challenges.

Abstract
Introduction The Japanese government declared a state of emergency (SoE) to control the spread of the coronavirus disease (COVID-19). However, the requirements of these SoE were less stringent than those in other nations. It has not been assessed whether soft containment policies were sufficiently effective in the promotion of social distancing or the reduction of human contact. Methods Mobility changes across different travel destinations, such as, (a) retail and recreation spaces; (b) supermarkets and pharmacies; (c) parks; (d) public transportation; (e) workplaces; and (f) residential areas, were analysed using the Google mobility index to assess social distancing behaviour in all Japanese prefectures between 15 February 2020 and 21 September 2021. The changes were evaluated through the utilisation of an interrupted time-series analysis after adjustment for seasonality and various prefecture-specific fixed-effects, and distinguishment of potential heterogeneity across multiple SoEs and the time that had passed after the declaration. Results The mobility index for retail and recreation exhibited an immediate decline of 7.94 percent-points (95%CI: -8.77 to -7.12) after the declaration of the SoE, and a further decline after the initial period (beta: -1.27 95%CI: -1.43 to -1.11). However, it gradually increased by 0.03 percent-points (95%CI: 0.02-0.03). This trend was similar for mobility in other places. Among the four SoEs, the overall decline in human mobility outside the home was the least significant in the third and fourth SoE, which suggests that people were less compliant with social distancing measures during these periods. Conclusions Although government responses to the pandemic may aid the controlling of human mobility outside the home, their effectiveness may decrease if these interventions are repeated and enforced for extended periods. A combination of these with other measures (i.e. risk-communication strategies) would enable even mild containment and closure policies to effectively curb the spread of the virus.

Abstract
OBJECTIVES While the development of vaccines against the Novel Coronavirus (COVID-19) brought hope of establishing herd immunity and ending the global pandemic, vaccine hesitancy can hinder the progress towards herd immunity. In this study, by analysing the data collected when citizens undergo public health restrictions due to the pandemic, we assess the determinants of vaccine hesitancy, reasons for hesitation and potential effectiveness of vaccine passports used to relax public health restrictions on mitigating vaccine hesitancy. DESIGN Cross-sectional study, longitudinal study and conjoint experimental design. SETTING An online survey conducted in Japan in July 2021. PARTICIPANTS A demographically representative sample of 5000 Japanese adults aged 20-74. PRIMARY OUTCOME MEASURES COVID-19 vaccination intention RESULTS: We found that about 30% of respondents did not intend to get vaccinated or had not yet decided, with major reasons for vaccine hesitancy relating to concerns about the safety and side effects of the vaccine. In line with previous findings, younger age, lower socioeconomic status, and psychological and behavioural factors such as weaker COVID-19 fear were associated with vaccine hesitancy. Easing of public health restrictions such as travel, wearing face masks and dining out at night was associated with an increase in vaccine acceptance by 4%-10%. Moreover, we found that more than 90% of respondents who intended to get vaccinated actually received it while smaller proportions among those undecided and unwilling to get vaccinated did so. CONCLUSION With a major concern about vaccine safety and side effects, interventions to mitigate against these may help to reduce vaccine hesitancy. Moreover, when citizens are imposed with restrictions, vaccine passports that increase their freedom may be helpful to increase vaccination rates.

Abstract
Circulating microRNAs (miRNAs) have been used as biomarkers for various diseases and physiological conditions in humans and mice; studies in domestic animals, particularly cattle, are limited. The importance of early pregnancy diagnosis (especially within the 21-d cow estrous cycle) in the livestock industry is extremely high. This study compared the circulating miRNAs in bred non-pregnant and pregnant Japanese Black cows, explored miRNAs as biomarkers for early pregnancy diagnosis, and established a measurement system that included selecting an appropriate reference miRNA and determining the effect of hemolysis on miRNA quantification in plasma. miRNA was extracted from the plasma of Japanese Black cows on day 21 after artificial insemination and subjected to a customized bovine oligonucleotide microarray for expression analysis. Differentially expressed miRNAs and reference miRNA candidates were selected and validated using reverse transcription-quantitative PCR (RT-qPCR). An appropriate endogenous reference miRNA for normalization was selected using NormFinder software. To evaluate the effect of hemolysis on miRNA quantification, hemolyzed samples were prepared using plasma from four cows in the estrous cycle and subjected to RT-qPCR. A total of 124 miRNAs were detected in bovine plasma by microarray analysis in bred non-pregnant and pregnant cows. The levels of five circulating miRNAs were significantly higher in pregnant cows than in bred non-pregnant cows, and 24 miRNAs were detected only in the pregnant group. NormFinder analysis and RT-qPCR validation showed that miR-2455 was an appropriate reference miRNA in the plasma of bred non-pregnant and pregnant Japanese Black cows, and miR-19b, miR-25, miR-29a, and miR-148a were significantly higher in the pregnant group. These four circulating miRNAs did not change during the estrous cycle and were less affected by hemolysis. In the current study, we found four miRNAs, miR-19b, miR-25, miR-29a, and miR-148a, which were present at high levels in the plasma of pregnant Japanese Black cows. Since these miRNAs are less affected by hemolysis, they may potentially be used as biomarkers for early pregnancy diagnosis in cattle.

Abstract
Cross-national studies of the linkage of health-care spending with population health have found surprisingly limited evidence of benefits. In this study, we investigated associations between national health spending and key health resources (numbers of hospital beds, physicians, and nurses) and utilization of cost-effective health services (antenatal care, attendance of trained staff at childbirth, and measles vaccination), sometimes in ways that curtail the benefits of that expenditure. Using annual panel data from 1990-2014 covering 140 countries, we show that variation in health spending as a share of gross domestic product is not associated with decreased mortality rates. It is also very weakly associated with increased health-care resources and health service utilization (elasticity smaller than 0.08), with the association being close to 0 in low-income countries. In addition, countries with a higher share of out-of-pocket spending have a significantly lower level of health resources and service utilization. These findings, rather than the ineffectiveness of health care, could explain the lack of impact of health spending. In contrast, gross domestic product per capita is significantly associated with increased health resources, a higher rate of service utilization, and lower mortality rates, suggesting that income is an important determinant of public health.

Abstract
While health effects of retirement have been well studied so far, previous findings remain inconclusive, and mechanisms underlying the linkage between retirement and health are unclear. This can be driven by regional or cohort heterogeneity as well as methodological differences, such as outcome measures and identification strategies; thus, much evidence needs to be accumulated. Utilising a national household survey conducted every year in 2004-2019 in Japan (the Japan Household Panel Survey), we evaluate the effects of retirement among Japanese adults aged 50-75 on their happiness and health in addition to other outcomes that could attribute to happiness or health changes (e.g. health behaviours, time use for some activities, and the expenses by item). As outcomes are not measured every year, we analyse 4,340-7,902 person-year observations by 756-1,389 individuals with the necessary information from 2009. To deal with the potential endogeneity of retirement, we adopt an instrumental variable approach utilising changes in retirement policy and public pension eligible age. Consequently, instruments seem valid only for men, and we find that retirement increases male retirees’ happiness and decreases psychological stress while effects on other health measures are not observed. Although their satisfaction with their income decline, perhaps because of the loss of their wage income, they tend to increase the proportion of expenses for cultural and recreational activities. Enhancement in personal life quality by more leisure activities and stress reduction from work, rather than improvements in health behaviours and physical health, may be key to understanding health benefits in retirement.

Abstract
Spousal loss is one of the most consequential negative life events for the surviving partners. While there is abundant research on mental health and well-being of widows, most of these studies rely on the post-bereavement data. In this study, we use the data from the National Survey of Japanese Elderly (NSJE), which is a publicly available longitudinal data set collected from Japanese adults aged 60 years and older. The current study uses the first seven waves of data from 1987 to 2006, where participants were followed every three to four years. Using the NSJE advances our understanding of the bereavement process as it allows us to observe the levels and trajectories of depressive symptom before, during, and after the loss of their spouses. In our analyses, we selected 522 participants (average age at bereavement: 75.0 years; 27% male) who experienced spousal loss at some point during the seven waves. We examined the trajectories of depressive symptoms assessed using CES-D as these participants transition to widowhood. The results showed a small significant increase in depressive symptoms leading up to the time of the loss. There was also a significant increase in symptoms at the time of the loss, but we did not observe any decline in symptoms after the loss. In addition, we found that their age at bereavement significantly moderated the pattern, such that the increase in depressive symptoms at the time of the loss was attenuated for older participants. The implications of these findings will be discussed.

Abstract
OBJECTIVE The aim of this study is to investigate the association between financial literacy and age as well as gender differences in financial literacy. METHODS We analyse a sample of 25,000 individuals from 'The Financial Literacy Survey 2016' conducted by the Central Council for Financial Services Information (Bank of Japan). The analysis focuses on the relationship of age and financial literacy as well as that of age and self-rated financial knowledge. To consider factors accounting for gender differences in financial literacy, we use the Blinder-Oaxaca decomposition method. To further our understanding of financial literacy, we conduct additional analyses on financial behaviour and attitude. RESULTS Although age is associated with increased financial literacy (Men, β: 0.249, standard error [SE]: 0.030; Women, 0.354, SE: 0.026), the growth rate decreases among the older respondents (Men, β: -0.002, SE: 0.000; Women, -0.003, SE: 0.000). However, the association between age and self-rated financial knowledge among men moves in the opposite direction (Age, β: -0.021, SE: 0.009, Age2, β: 0.000, SE: 0.000). Furthermore, female respondents are likely to be less financially literate than their male counterparts (β: -0.586, SE: 0.095) due to gender differences in the distribution of the factors that affect financial literacy (specifically education), their responses to financial literacy, and the interactions of these effects. In contrast to knowledge-based financial literacy, financial behaviour and attitudes among women are more preferable to those among men, namely, more premeditated. CONCLUSION Financial literacy increases until about one's early 60s, after which it declines, while confidence in financial literacy reflects the inverse trend, especially among men. Additionally, men are more financially literate than women; however, these differences could be mitigated through education. Meanwhile, financial behaviour and attitudes among men are less premeditated. Thus, policies are needed that can help older adults with their financial decision-making, enhance women's financial literacy, and improve men's financial behaviours and attitudes.

Abstract
Abstract
Background
Achieving universal health coverage (UHC) is a target of the Sustainable Development Goals, and the monitoring of its progress is of use to clarify what to be enhanced for better health. While the WHO and the World Bank Group jointly developed a scale with the above purpose (WHO/WB index: Hogan et al., 2018), it fails to reflect the fact that different needs to health coverages may exist depending on a stage of epidemiological transition.
Methods
To consider potential differences in health coverage needs depending on the stage of the epidemiological transition, we reformulated the index by incorporating weight as the proportion of age-adjusted mortality rate among monitored domains (i.e. reproductive, maternal, new-born and child health, infectious disease, non-communicable diseases [NCD]), of which data collected from the WHO Global Health Observatory. Additionally, we utilised indicators of policy achievements on NCD by the WHO’s Noncommunicable Diseases Progress Monitor 2015.
Results
The UHC progress monitored by the WHO/WB index had a mean of 61.83 (%) while it declined by about 4% point on average when NCD indicators were replaced. Furthermore, the UHC progresses evaluated with weights calculated from disease burden decreased by about 10% point for both measures, suggesting that some countries may not provide demanded health coverages.
Conclusion
The UHC progress decreased when disease burden for each country was taken into consideration. This indicates the necessity to assess the UHC progressby reflecting disease structure of each country, not by an identical scale for all nations.
Key messages
The monitoring of universal health coverage is required to reflect disease structure of each country.

Abstract
Physical inactivity is a pandemic that requires intensive, usually costly efforts for risk reduction of related chronic diseases. Nevertheless, it is challenging to determine the effectiveness of physical activity in healthcare cost reduction based on existing literature. Therefore, this study aimed to investigate the impact of physical activity (daily steps) on healthcare costs utilising the data retrieved from a health promotion project (the e-wellness Project, held in three municipalities in Japan). Evaluating the effects of daily steps, measured by pedometers, on healthcare costs by a quasi-experimental approach among participants aged 40–75 years (about 4000 person-years of observation, between 2009 and 2013), we found that a one-step-increase in the annual average daily step reduced outpatient healthcare costs by 16.26 JPY (≒ 0.11 GBD) in the short run. Based on the assumption of a dynamic relationship between the health statuses in multiple years, the long-run effects of daily steps on healthcare costs were estimated at 28.24 JPY (≒ 0.20 GBD). We determined the health benefits of walking in a sample of middle-aged and older Japanese adults by our findings that an increase in step counts reduced healthcare costs.

Abstract
The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermion and the Z2 gauge flux. It was proposed recently that fingerprints of fractional excitations are encoded in the phonon spectra of Kitaev quantum spin liquids through a novel fractional-excitation-phonon coupling. Here, we detect anomalous phonon effects in α-RuCl3 using inelastic X-ray scattering with meV resolution. At high temperature, we discover interlaced optical phonons intercepting a transverse acoustic phonon between 3 and 7 meV. Upon decreasing temperature, the optical phonons display a large intensity enhancement near the Kitaev energy, JK~8 meV, that coincides with a giant acoustic phonon softening near the Z2 gauge flux energy scale. These phonon anomalies signify the coupling of phonon and Kitaev magnetic excitations in α-RuCl3 and demonstrates a proof-of-principle method to detect anomalous excitations in topological quantum materials.

Abstract
There is no consensus on which parental socioeconomic indicators should be used to define adolescents’ socioeconomic status (SES). Utilising the data for 3154 parent-adolescent pairs obtained from the sample of the Survey of Lifestyle Value of Parents and Children 2011 conducted by the Cabinet Office in Japan, the associations between adolescent’s subjective economic status, parental SES (i.e. education, occupation, and household income), and child health-related outcomes (i.e. self-rated health, dietary and oral health behaviours) were analysed using multilevel mixed-effects ordered logistic regression to investigate heterogeneity in these relationships across SES indicators and health outcome measures. Results demonstrated that income was the strongest predictor of adolescent health outcomes, suggesting that adolescents in the middle- or high-income groups tended to report better health status compared to the low-income group, have a higher frequency of having breakfast, and more likely to regularly brush their teeth by 24% (OR 1.24, 95% CI [1.06–1.46]) to 66% (OR 1.66, 95% CI [1.30–2.12]). Parental education was also related to child health-related behaviours, with higher levels of habitual healthy behaviours being observed in the middle- and high-education groups than in the low-education group by 15% (OR 1.15, 95% CI [1.01–1.32]) to 63% (OR 1.63, 95% CI [1.31–2.03]). Future studies regarding health disparities among children/adolescents should carefully choose an SES indicator, taking multiple pathways between each SES indicator and health/health behaviours into consideration.

Abstract
The anomalous Hall effect (AHE) is an intriguing transport phenomenon occurring typically in ferromagnets as a consequence of broken time reversal symmetry and spin-orbit interaction. It can be caused by two microscopically distinct mechanisms, namely, by skew or side-jump scattering due to chiral features of the disorder scattering, or by an intrinsic contribution directly linked to the topological properties of the Bloch states. Here we show that the AHE can be artificially engineered in materials in which it is originally absent by combining the effects of symmetry breaking, spin orbit interaction and proximity-induced magnetism. In particular, we find a strikingly large AHE that emerges at the interface between a ferromagnetic manganite (La0.7Sr0.3MnO3) and a semimetallic iridate (SrIrO3). It is intrinsic and originates in the proximity-induced magnetism present in the narrow bands of strong spin-orbit coupling material SrIrO3, which yields values of anomalous Hall conductivity and Hall angle as high as those observed in bulk transition-metal ferromagnets. These results demonstrate the interplay between correlated electron physics and topological phenomena at interfaces between 3d ferromagnets and strong spin-orbit coupling 5d oxides and trace an exciting path towards future topological spintronics at oxide interfaces.

Abstract
INTRODUCTION Disability development using age as the axis was void in the literature. Identification of the age trajectory of disability development across populations enables preparation for aging-related policies when conducting cross-national comparisons. This study compared three indicators of the development of physical disability in populations of Taiwan and Japan. METHODS Data comprised two nationally representative panel surveys (1) the Taiwan Longitudinal Study on Aging (N = 3,037) in 1996-2011 and (2) the National Survey of the Japanese Elderly in 1996-2012 (N = 1,974). Older adults (65+) were examined longitudinally. Activities of daily living (ADL), instrumental activities of daily living (IADL), and mobility disability development during aging were analyzed using multilevel models. RESULTS After age standardization, Japan reported higher prevalence rate of ADL disability (14.95% vs. 9.65%) but lower IADL (19.30% vs. 30.36%) and mobility disability (36.07% vs. 49.82%) as compared with Taiwan. ADL limitation occur (ADL limitation>=1) at the age of 77.9 and 77.2 for populations in Japan and Taiwan, respectively. Populations reached three ADL limitations at the age of 86.7 and 85.0 in Japan and in Taiwan, respectively. IADL limitation occur (IADL limitation>=1) at the age of 79.1 and 74.5 for populations in Japan and Taiwan, respectively. Mobility limitation occur (Mobility limitation>=1) at the age of 70.7 and 65.3 for populations in Japan and Taiwan, respectively. CONCLUSIONS Older adults generally do not report ADL limitation until 77 and do not face serious disability until 85 or 86 in Taiwan or Japan, respectively. Mobility limitation occurs at a various age in different countries.

Abstract
Although retirement age is increasing in aging societies, its impact on individuals and communities is unclear. This study examined how age moderates the linkage between transition into retirement and participation in productive and non-productive social activities after retirement, using a nationwide longitudinal survey with a probability sample of Japanese aged 60 and over (n = 3,493). Multinomial logistic regression analyses were performed to predict changes in volunteering and hobbies/learning during 3-5 years of follow-up and their participation level at the follow-up. The significant interactions between change in work status (remained working as reference, full/partial retirement, remained not-working) and age at baseline showed that fully retired persons were more likely to increase these activities than remained workers only when they retired by their early seventies. Thus it is important to encourage engagement in social activities before retirement and remove psychological and environmental barriers that hinder starting new activities at old age.

Abstract
OBJECTIVES This study aimed to assess the relationship between social isolation and cognitive functioning. METHODS Data were retrieved from the National Survey of the Japanese Elderly, a nationally representative sample of Japanese adults, aged 60 years or older. We estimated a social isolation index to incorporate variables, such as social interactions, social engagement, and social support, with perceived social isolation, for a comprehensive measurement. The association of social isolation with cognitive functioning was assessed using a panel data fixed-effects model, controlling for age, socioeconomic status, health-related variables, and time-invariant heterogeneity. Moreover, we conducted analyses using the System Generalised Method of Moments (GMM) to address the dynamic relationship of cognitive functioning and potential endogeneity. RESULTS For both men and women, the association between social isolation and cognitive functioning was significant, particularly among those aged 75 or older, as a 1% increase in social isolation was associated with decreased cognitive functioning (24% decrease for men, and 20% decrease for women). However, this association was not confirmed by the System GMM, after addressing endogeneity. DISCUSSION Our findings potentially suggest that the association between social relationship and cognitive functioning reported in previous studies was biased, due to endogeneity. Although we did not observe causal impacts, this does not necessarily mean that social isolation does not have a negative impact on health, as both positive and negative consequences of social relationships may exist. Further research is needed to reveal the causal relationship, as well as the detailed mechanisms of health effects of social relationships.

Abstract
BACKGROUND Japan has the largest aging population in the world, thus, a focus on frailty is important in clinical geriatric practice. Using a nationally representative sample, this study provided national estimates of the prevalence of frailty among community-dwelling older Japanese people. We also examined variations in the prevalence by sociodemographic characteristics, health conditions, and geographical regions. METHODS Data came from the National Survey of the Japanese Elderly in 2012. The data were collected using a home visit and face-to-face interviews with trained interviewers. The sample consisted of 2206 adults aged ≥65 years. We used the widely accepted definition of physical frailty phenotype and calculated weighted estimates of the prevalence of frailty. RESULTS Overall estimated prevalence was 8.7 % (7.5 %-9.9 %) for frail, 40.8 % (38.7 %-42.9 %) for prefrail, and 50.5 % (48.4 %-52.6 %) for robust. Frailty was more prevalent in older groups, women, and those with lower socioeconomic status, which was measured by education and household income. Frail people tended to have worse health. We also observed a regional variation: frailty prevalence tended to be higher in eastern than western Japan. CONCLUSIONS This study provides important evidence on the prevalence of frailty in older Japanese people and found substantial disparities by sociodemographic characteristics, health conditions, and geographical regions.

Abstract
This research aimed to assess the relationship between social isolation and cognitive functioning among older Japanese adults, thereby expanding the relevant literature in two main ways. First, we estimated a social isolation score to incorporate objective measurements of social isolation into a subjective measurement. Second, a panel data analysis was utilised to consider the change in the social isolation score and time-invariant unobserved heterogeneity. Data were derived from the National Survey of the Japanese Elderly, a survey of a sample of older Japanese adults aged 60 to 99 in waves 3 through 7, which contain unified information of social isolation. The sample included 4,889 observations (1,836 individuals) for men and 6,621 observations (2,433 individuals) for women. The predicted isolation score was obtained by a random-effects ordered logistic regression (i.e., regressing a subjective feeling of isolation on variables regarding social interaction, social support, and social engagement). The association of cognitive functioning with the isolation score was estimated by a fixed-effects ordinary least squares regression, controlling for age, socioeconomic variables, health conditions, and time fixed-effects. We found that increased isolation was associated with a deterioration in cognitive functioning, both for men (coefficient: 0.66, robust standard error [SE]: 0.30) and women (coefficient: 0.90, SE: 0.26). Findings of this research highlight the importance of actions aimed at inhibiting social isolation for the prevention of cognitive decline. This approach is potentially beneficial for developing measurements of both subjective and objective social isolation and estimating the longitudinal relationship between social isolation and cognitive functioning.

Abstract
Abstract
Background
Recently, some studies have highlighted proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors produce incremental low-density lipoprotein cholesterol (LDL-C) lowering effect. However, it is unknown whether the lipid composition of plaque changes is associated with serum LDL-C reduction due to PCSK9 inhibitors administration.
Purpose
The purpose of this study was to determine the effects of PCSK9 inhibitor (PCSK9i) on coronary plaque component in patients with a history of coronary artery disease (CAD) assessed by near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS).
Methods
A total of 67 non-culprit coronary segments were identified in 34 patients. These lesions were analyzed utilizing NIRS-IVUS at baseline and follow-up coronary angiography (CAG). The subjects were divided into two groups according to lipid-lowering treatment; administration of PCSK9i group (PCSK9i: 19 segments, 9 patients) and traditional statin treatment group (Control: 48 segments, 25 patients). The change of lipid-rich plaque distribution between baseline and follow-up NIRS-IVUS was defined as the change of maximal lipid core burden index (LCBI) score for each of the 4-mm longitudinal segments (maxLCBI4mm).
Results
Mean duration from baseline to follow-up CAG was 239.4±52.4 days in the PCSK9i group and 341.0±84.1 days in the Control group (p<0.001). Despite the higher total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the PCSK9i group at baseline (206.6±40.9 mg/dl vs. 168.5±37.1 mg/dl, 131.5±35.4 mg/dl vs. 100.0±29.5 mg/dl; respectively, p<0.001 for both), the PCSK9i group was significantly lower TC and LDL-C at the follow-up (111.5±23.5 mg/dl vs. 157.4±27.8 mg/dl, 40.8±15.7 mg/dl vs. 86.2±19.6 mg/dl; respectively, p<0.001 for both). Furthermore, the PCSK9i group induced greater regression of maxLCBI4mm than that of Control group (99.6±156.6 vs. 27.9±118.0, p=0.046) (Figure).
Figure 1
Conclusion
Compared with traditional statin therapy, PCSK9i treatment resulted in a greater decrease in lipid component in non-culprit coronary plaques. Therefore, PCSK9i may be useful option in preventing from adverse coronary events for the patients with CAD.

Abstract
Abstract
Background
Critical limb ischemia (CLI) is the most progressed manifestation of peripheral artery disease. Although patients with CLI commonly complicate with severely calcified lesions in infrapopliteal lesions, the prognostic impact of infrapopliteal arterial calcification on wound healing in patients with CLI has not been systematically studied.
Purpose
The aim of current study was to elucidate the prognostic impact of infrapopliteal arterial calcification on wound healing in CLI undergoing endovascular therapy (EVT).
Methods
This study enrolled 639 CLI patients with tissue loss (age 74±10 years, male 62%, diabetes 69%, hemodialysis 57%, Rutherford class 5 77%, class 6 23%) primarily treated with EVT for the infrapopliteal lesions between April 2010 and December 2015. Arterial calcification was assessed by high intensity fluoroscopy and classified into 3 groups as follows; 1) none, 2) unilateral and 3) bilateral calcification. The primary outcome measure was complete wound healing. The predictors of the outcome were evaluated by Cox proportional hazards regression analysis.
Results
During a mean follow-up period of 22±19 months, 1-year wound healing rate were 59.0%. In Kaplan-Meier analysis, 1-year wound healing rate was worse in patients with bilateral calcification than in those with unilateral or none calcification (Figure, 46.2% versus 55.1% versus 67.8%, P<0.001). After multivariate analysis, the predictors of wound healing were non-ambulatory status (hazard ratio (HR) 0.67 [95% confidential interval (CI) 0.53–0.85], P=0.001) and bilateral calcification (HR 0.75 [95% CI 0.47–0.98], versus none or unilateral calcification, P=0.036).

Conclusion
Infrapopliteal Arterial calcification as well as non-ambulatory status was associated with wound healing in patients with CLI.

Abstract
Abstract
Background
Polymer-free biolimus A9-coated stent (DCS) has currently emerged as expected better arterial healing compared to durable polymer drug-eluting stent (DP-DES). However, superiority of DCS on arterial healing over DP-DES has not been well elucidated using intracoronary images.
Methods
This study examined 288 stents in 224 patients with de novo coronary artery lesions. We angioscopically compared 55 DCS from 35 patients with 233 DP-DES from 189 patients 10±2 months after the implantation. We assessed thrombus adhesion, which is a marker of incomplete re-endothelialization. Dominant neointimal coverage (NIC) grade, heterogeneity of NIC and maximum yellow color of plaque underneath the stent were also evaluated. Neointimal coverage was graded as follows: grade 0, stent struts exposed; grade 1, struts bulged into the lumen, although covered; grade 2, struts embedded by the neointima, but translucent; grade 3, struts fully embedded and invisible. NIC was judged as heterogeneous when differences in the NIC grade became apparent. Yellow plaque was graded as follows: grade 0, white; grade 1, light yellow; grade 2, yellow; grade 3, intensive yellow.
Results
Thrombus adhesion was similar between DCS and DP-DES (29% versus 23%, P=0.32). Dominant NIC was greater in DCS than in BP-DES (P<0.001), while NIC was more heterogeneous in DCS than in BP-DES (P=0.001, Figure). Maximum yellow color of stented segment was similar between DCS and DP-DES (P=0.09).
Conclusion
DCS provided similar thrombus adhesion to DP-DES, which suggested similar re-endothelialization 10 months after implantation. However, DCS showed thick and heterogeneous NIC compared to DP-DES. The specific feature of polymer-free and Biolimus A9 would cause the difference, and further investigation is necessary to evaluate the longer-term safety and efficacy.

Abstract
Abstract
Background
Pulmonary vein isolation (PVI) using cryoballoon requires contrast medium injection for the confirmation of appropriate venous occlusion. However, some patients have contra-indications against contrast use such as allergy for contrast medium, bronchial asthma or renal dysfunction. We hypothesized that intra-cardiac echocardiographic observation of microbubble leakage after saline injection from the cryoballoon lumen can be used as a maker of incomplete venous occlusion.
Purpose
The aim of this study was to assess the effect of echo-guided approach using saline injection on the acute clinical outcomes as well as the amount of contrast medium.
Methods
Twenty consecutive patients with paroxysmal atrial fibrillation (AF) were studied. They had any reason to avoid using contrast medium. Plain CT scan was performed in all cases to understand the anatomical features. Intra-cardiac echocardiography was used in all cases to guide transseptal puncture and to confirm pulmonary-vein occlusion. Procedural results and clinical outcomes were compared with patients who were performed by the conventional method (n=279).
Results
In all study patients, we could perform PVI without using contrast medium. A total of 2 patients required touch-up ablation using radiofrequency ablation catheter. The procedure time (85±23 vs 86±27 min, P=0.84), the dose of radiation exposure (108±78 vs. 140±133 mmGy/m2, P=0.29), and ratio of requiring touch-up ablation (5% vs 4%, P=0.81) were similar between the study group and the reference group. There was no significant difference in the AF-free survival rate (73% vs. 76%, P=0.79) during a follow-up period of 14±6 months.

Conclusion
Echo-guided approach using saline infusion was effective and less invasive in terms of reduction of contrast use.

Abstract
Abstract
Background
Biodegradable polymer drug-eluting stent (BP-DES) has been developed to improve clinical outcomes after percutaneous coronary intervention (PCI) for patients presenting coronary artery disease (CAD). Although BP-DES showed non-inferior safety and efficacy to durable polymer DES (DP-DES) in several randomized clinical trials, hemodialysis (HD) patients, who have been well known as high risk population for adverse events, were excluded in the most of trials. Therefore, there are limited data comparing the clinical outcomes between BP-DES and DP-DES in HD patients with CAD after PCI.
Purpose
The purpose of this study was to investigate clinical outcomes in HD patients after BP-DES implantation compared with those after DP-DES implantation.
Methods
We retrospectively analyzed 234 HD patients (male 74%, mean age 71±10 years) undergoing PCI for 404 lesions with 472 DESs (71 patients for 138 lesions with 170 BP-DESs [91 Ultimaster and 79 Synergy] and 163 HD patients for 266 lesions with 302 DP-DESs [219 Xience, 53 Promus and 30 Resolute]) from 2011 to 2017. Two-year clinical outcomes were compared between BP-DES group and DP-DES group. The primary outcome measure was the incidence of target lesion revascularization (TLR), while the secondary outcome measures were the occurrence of cardiac death (CD), stent thrombosis (ST), myocardial infraction (MI), target vessel revascularization (TVR), non-TVR and major adverse cardiac event (MACE) defined as a composite of CD, MI, and TVR. Outcome measures were estimated by the Kaplan-Meier method and the differences between BP-DES group and DP-DES group were assessed by the log-rank test. We also conducted Cox's proportional hazard model to identify predictors for TLR occurrence.
Results
Baseline patient and lesion characteristics were similar between the two groups. The two-year incidence of TLR was not significantly different between BP-DES group and DP-DES group (14.1% vs. 22.2%, p=0.391). The two-year incidences of CD (17.3% vs. 17.5%, p=0.381), ST (0% vs. 3.9%, p=0.133), MI (4.2% vs. 5.8%, p=0.965), TVR (21.3% vs. 27.5%, p=0.586), non-TVR (26.1% vs. 31.3%, p=0.439) and MACE (41.1% vs. 42.6%, p=0.526) were also not different between the two groups. After multivariate analysis, diabetes mellitus (hazard ratio 1.97; 95% confidence interval 1.03–3.78, p=0.004) was independently associated with TLR occurrence in HD patients.
Two-year clinical outcomes of HD patient
Conclusions
At two-year follow-up after PCI, BP-DES had comparable safety and efficacy profiles to DP-DES in HD patients presenting CAD.

Abstract
Studies across Europe and the US report that childhood socioeconomic disadvantage is associated with poorer health in adulthood. By contrast, a study in Japan suggests that childhood socioeconomic disadvantage may be positive for adult health. In this paper, we assess the association between intergenerational income mobility and self-rated health in Japan, using detailed childhood income data for 1610 men and 1885 women aged 30-49 years. We use an instrumental variable approach to identify the causal effect of upward income mobility on adult health. We find that low father's income during childhood is associated with smoking and alcohol consumption in adult life for both men and women. For men, upward income mobility was associated with worse health. Certain behavioural choices related to income mobility, such as long working hours, may have detrimental health effects.

Abstract
PURPOSE This article aimed to examine the causal relationships of hours of work with health behaviors and health outcomes. METHOD The data were derived from Japan Household Panel Survey/Keio Household Panel Survey. In total, data from 2677 men and 2170 women were analyzed to show the effects of hours of work on body mass index, smoking, and sleeping hours. To deal with the potential endogeneity of decisions about hours of work, the instrumental variable approach was used. RESULTS Hours of work had a negative impact on hours of sleep among men (coefficient [coef.], -0.371; 95% confidence interval [CI], -0.519 to -0.223). Longer hours of work also increased the probability of men being obese (coef., 1.108; 95% CI, 0.234-1.981) and the number of cigarettes they smoked each day (coef., 1.007; 95% CI, 0.037-1.978). For women, longer hours of work increased the probability of being obese (coef., 0.029; 95% CI, 0.009-0.050) and decreased the hours of sleep (coef., -0.416; 95% CI, -0.618 to -0.214). CONCLUSIONS This article suggests that the health consequences of long hours of work include health behaviors and health outcomes that can lead to higher risks of morbidity and mortality.

Abstract
Balloon occlusion is a potential method for inducing hyperemia to measure post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR). The objective of this study was to determine the clinical usefulness of post-occlusional hyperemia. FFRs measured using post-occlusional hyperemia caused by 30 (FFRoccl30) and 60 s (FFRoccl60) of balloon occlusion after PCI were compared in 60 lesions from 60 patients. The duration of hyperemia was also measured. There was a strong correlation between FFRoccl30 and FFRoccl60 (r = 0.969, p < 0.01). The duration of hyperemia was significantly longer with FFRoccl60 than with FFRoccl30 (68 ± 23 vs. 37 ± 15 s, p < 0.01). The time required for pullback curve analysis was around 45 s. However, in 7 (12%) cases, the duration of hyperemia with FFRoccl60 was < 45 s, which was not enough for pull-back curve analysis. To predict the duration of hyperemia with FFRoccl60 ≥ 45 s, the receiver operating characteristic curve analysis revealed a cut-off value of 25 s of hyperemia with FFRoccl30. FFRoccl30 is sufficient for diagnostic purposes. FFRoccl60 is suitable for pull-back curve analysis in select cases based on predictions made using the duration of hyperemia with FFRoccl30.

Abstract
AIM In Japan, with the largest percentage of population aged 65 years or over, a dementia strategy is needed not only from a medical perspective, but also from a social policy viewpoint. This study aimed to verify the association between socioeconomic factors and cognitive decline among Japanese elderly people. METHODS Cognitive decline was assessed over a 15-year follow-up period using memory tests or through identifying missing/proxy responses to survey questions due to cognitive dysfunction. I analysed 1886 men and 2102 women in Japan, using competing risk models for cognitive decline, to consider survival effects. Survival effects have not been considered so far although those who live longer may be more likely to experience cognitive decline. RESULTS Men with higher income had a lower risk of cognitive decline (sub-hazard ratio [SHR]: 0.997, 95% confidence interval (CI): 0.995-0.999). Women with higher education had a lower risk of cognitive decline: 8 to 9 years (SHR: 0.646, 95% CI: 0.457-0.914) and ≥12 years (SHR: 0.360, 95% CI: 0.164-0.794) than women with 0 to 7 years of education. CONCLUSION This study suggests that cognitive decline among the elderly Japanese population is associated with socioeconomic factors, such as income and education, even after taking survival effects into account.

Abstract
OBJECTIVE To assess the performance of angiography derived Fractional Flow Reserve (FFRangio) in multivessel disease (MVD) patients undergoing angiography. BACKGROUND FFR is the reference standard for physiologic assessment of coronary stenosis and guidance of revascularization, especially in patients with MVD, yet it remains grossly underutilized. The non-wire based FFRangio performs well in non-MVD patients, but its accuracy in MVD is unknown. METHODS A prospective clinical study was conducted at Gifu Heart Centre, Japan. Patients underwent physiologic assessment of all relevant coronary lesions using wire-based FFR (wbFFR) and FFRangio. Primary outcome was diagnostic performance (sensitivity, specificity, accuracy) for FFRangio with wbFFR as reference. Other outcomes were the correlation between wbFFR/FFRangio, time required for wbFFR/FFRangio measurements, and the effect of wbFFR/FFRangio on the reclassification of coronary disease severity. RESULTS Fifty patients (118 lesions in total) were included. Mean age was 72 ± 9 years, 72% were male, 36% had triple vessel disease and the average SYNTAX score was 13. The mean measurement of wbFFR and FFRangio were 0.83 ± 0.12 and 0.81 ± 0.11, respectively. Accuracy, sensitivity and specificity for FFRangio were 92.3% (95% CI 79.1-98.4%), 92.4% (95% CI 84.3-97.2%) and 92.4% (95% CI 87.4-97.3%), respectively. Pearson's r between wbFFR and FFRangio was 0.83. FFRangio measurement was faster than wbFFR (9.6 ± 3.4 vs. 15.0 ± 8.9 min, p < 0.001). CONCLUSIONS In patients with MVD, FFRangio shows good correlation and excellent diagnostic performance compared to wbFFR, and measuring FFRangio is faster than wbFFR. These results highlight the potential clinical benefits of utilizing FFRangio among patients with MVD.

Abstract
Objective To estimate the average treatment effect of working past the current retirement age on the health of Japanese men. Methods We used publicly available data from the National Survey of Japanese Elderly, extracting a sample of 1288 men who were 60 years or older. Survey respondents were followed-up for at most 15 years for the onset of four health outcomes: death, cognitive decline, stroke and diabetes. By using the propensity score method, we adjusted for the healthy worker effect by incorporating economic, sociodemographic and health data in the form of independent variables. By calculating the differences in times to a health outcome between those in employment and those not employed, we estimated the average treatment effects on health of being in paid work past retirement age. Findings Compared with those not employed, those in employment lived 1.91 years longer (95% confidence interval, CI: 0.70 to 3.11), had an additional 2.22 years (95% CI: 0.27 to 4.17) before experiencing cognitive decline, and had a longer period before the onset of diabetes and stroke of 6.05 years (95% CI: 4.44 to 7.65) and 3.35 years (95% CI: 1.42 to 5.28), respectively. We also observed differences between employees and the self-employed: the self-employed had longer life expectancies than employees. In terms of years to onset of diabetes or stroke, however, we only observed significant benefits to health of being an employee but not self-employed. Conclusion Our study found that being in employment past the current age of retirement had a positive impact on health.

Abstract
SummaryThe synthetic thrombin-inhibitor termed No. 205 (N-α-dansyl-L-arginine-4-ethyl-piperidine amide) found in our laboratories was studied kinetically using synthetic peptide substrates. The following results were obtained. 1. No. 205 inhibited thrombin competitively with bz-Phe-Val-Arg-pNA and the Ki value obtained was extremely small, 3.7 × 10-8 M. 2. No. 205 also inhibited trypsin competitively with bz-Phe-Val-Arg-pNA but the Ki value obtained was far larger than that for thrombin, 1.0 × 10-5 M. 3. No. 205 inhibited F. Xa, plasmin and urokinase only to a small extent when estimated using 2 × 10-4 M D-Val-Leu- Lys-pNA, bz-Ile-Glu-Gly-Arg-pNA and Glu-Gly-Arg-pNA, respectively. 4. No. 205 differed from APPA in its specific inhibitory spectrum for thrombin as compared to trypsin, plasmin and F. Xa. The above results indicate that No. 205 is an extremely potent and highly selective reversible thrombin-inhibitor.
