Abstract
Depressive disorders are among the leading causes of disability globally. However, information on the burden of depressive disorders in Vietnam is limited. We aimed to analyse the burden of depressive disorders in Vietnam from 1990 to 2019. Using data from the Global Burden of Disease Study 2019, prevalence and disability-adjusted life-years (DALYs) were used as indicators to analyse the burden of depressive disorders by age and sex. In 2019 in Vietnam, depressive disorders comprised 2629.1 thousand (95% uncertainty interval (UI): 2233.3-3155.9) estimated cases and 380.6 thousand (95% UI: 258.9-533.8) estimated DALYs. The crude prevalence rate of depressive disorders was higher among females than among males. The DALYs of depressive disorder accounted for a higher percentage of the total all-cause DALYs in the 10-64-year age group than in other age groups. Major depressive disorder was the largest contributor to the burden of depressive disorders. From 1990 to 2019, the crude prevalence and DALY rates per 100 000 population due to depressive disorders increased significantly, whereas age-standardised rates of prevalence and DALYs decreased significantly; the respective average annual percent changes were 0.88% (95% confidence interval: 0.87 to 0.89), 0.68% (0.66 to 0.70), -0.20% (-0.21 to -0.19), and -0.27% (-0.28 to -0.25). Although the age-standardised prevalence rate was lower than that seen globally, depressive disorders were considerable mental health issues in Vietnam. This study will help governments and policymakers to establish appropriate strategies to reduce the burden of these disorders by identifying the priority areas and individuals.

Abstract
The persistent ascension of childhood obesity on a global scale constitutes a significant quandary. The prevalence of childhood obesity in Japan peaked in the early 2000s and has been reported to have declined since then, but recent data and its trend including the novel coronavirus disease 2019 (COVID-19) pandemic era are not available. Moreover, there is a dearth of studies examining the correlation between the trend in childhood obesity and exercise habits over the past decade. This study aims to examine the changes in the prevalence of obesity, physical fitness, and exercise habits over the past 10 years in Japanese children. We investigated the prevalence of childhood obesity in Japan, using the School Health Statistics Survey data from 2012 to 2021. The dataset has a sample size representative of children nationwide and includes variables for obesity, such as height, weight, and age. Data were classified into groups by sex and age (6-8, 9-11, and 12-14 years age). Children weighing 20% or more of the standard body weight are classified as obese. The annual percentage changes and average annual percentage changes were estimated using the joinpoint regression model. We also examined the trends in the physical fitness test score and exercise time. Average annual percentage changes of boys increased, especially in the 6- to 8-year age group (3.4%-4.6%). For girls, average annual percentage changes had increased in 6- to 8-year (2.5%-4.0%) and 9- to 11-year (0.9%-2.2%) age groups. Since the late 2010s, significantly increasing annual percentage changes were observed in 12- to 14-year age boys (6.7%-8.9%) and girls of many age groups (2.6%-8.6%). The physical fitness test score and exercise time showed decreasing trends since the late 2010s. Childhood obesity may have generally risen in Japan, in the last decade. Encouraging healthy eating and physical activity through school policies and curricula is necessary.

Abstract
BACKGROUND AND OBJECTIVE Adverse drug events (ADEs) are becoming a significant public health issue. However, reports on ADE-related mortality are limited to national-level evaluations. Therefore, we aimed to reveal overall trends in ADE-related mortality across the 21st century on an international level. METHODS This observational study analysed long-term trends in ADE-related mortality rates from 2001 to 2019 using the World Health Organization Mortality Database. The rates were analysed according to sex, age and region. North America, Latin America and the Caribbean, Western Europe, Eastern Europe and Western Pacific regions were assessed. Fifty-four countries were included with four-character International Statistical Classification of Disease and Related Health Problems, Tenth Revision codes in the database, population data in the World Population Prospects 2019 report, mortality data in more than half of the study period, and high-quality or medium-quality death registration data. A locally weighted regression curve was used to show international trends in age-standardised rates. RESULTS The global ADE-related mortality rate per 100,000 population increased from 2.05 (95% confidence interval 0.92-3.18) in 2001 to 6.86 (95% confidence interval 5.76-7.95) in 2019. Mortality rates were higher among men than among women, especially in those aged 20-50 years. The population aged ≥ 75 years had higher ADE-related mortality rates than the younger population. North America had the highest mortality rate among the five regions. The global ADE-related mortality rate increased by approximately 3.3-fold from 2001 to 2019. CONCLUSIONS The burden of ADEs has increased internationally with rising mortality rates. Establishing pharmacovigilance systems can facilitate efforts to reduce ADE-related mortality rates globally.

Abstract
Autoimmune tissues may contain ectopic germinal centers (EGCs). However, these structures have never been described in the liver of patients suffering from autoimmune hepatitis (AIH). We retrospectively reviewed histological features of 120 definite AIH cases, and found 10 cases harboring markers of EGCs. In these cases, CD21+ follicular dendritic cells were intermixed with CD3+ T and CD20+ B lymphocytes. The latter expressed the GC-specific marker bcl6, and some were proliferative as assessed by Ki67 expression. Antibody-secreting cells (ASCs) defined by expression of the mum-1 transcription factor and presence of cytoplasmic IgMs were usually present in the periphery of these structures, but some were also present within the EGCs. Notably, some ASCs were IgG-switched. Common treatment applied to AIH patients achieved biochemical normalization as efficiently as in patients without EGCs. In the present study, we provide the proof for the occurrence of functional EGCs enabling differentiation of B cells into ASCs and occurrence of immunoglobulin switch in AIH livers.

Abstract
A 58-year-old man with human immunodeficiency virus (HIV) infection presented with a week-long history of gross hematuria, nephrotic proteinuria, and acute kidney injury. The patient was non-adherent with combination antiretroviral therapy. A kidney biopsy showed cellular crescents with disruption of Bowman's capsule, C3-dominant immune complex deposition, consistent with HIV-associated immune complex kidney disease (HIVICK). During the course, his worsening kidney function warranted initiation of hemodialysis. This case highlights the fact that HIV patients are at an increased risk of developing HIVICK, especially in the setting of non-adherence. A greater understanding of HIVICK among HIV patients should promote additional investigation into its etiology and viable treatments.

Abstract
Globally, the numbers of head and neck cancer (HNC) cases and related deaths have recently increased. In Japan, few studies have examined crude or age-adjusted HNC mortality rates. Therefore, this study aimed to determine the trends in crude and age-adjusted mortality rates for HNC per million individuals in Japan from 1999 to 2019. Data on HNC-associated deaths were extracted from the national death certificate database using the International Classification of Diseases, Tenth Revision (n = 156,742). HNC mortality trends were analysed using joinpoint regression models to estimate annual percentage change (APC) and average APC (AAPC). Among men, no significant change was observed in the age-adjusted death rate trend from 1999 to 2014; however, a marked decrease was observed from 2014 to 2019. No changing point was observed in women. Age-adjusted mortality rates continuously decreased over the 21-year period, with an AAPC of -0.7% in men and -0.6% in women. In conclusion, the overall trend in age-adjusted rates of HNC-associated deaths decreased, particularly among men, in the past 5 years. These results will contribute to the formulation of medical policies to develop targeted screening and prevention programmes for HNC in Japan and determine the direction of treatment strategies.

Abstract
INTRODUCTION We investigated the effect of social media-based interventions on COVID-19 vaccine intention (VI) and confidence in Japan. METHODS We conducted a three-arm randomised controlled trial between 5 November 2021 and 9 January 2022 during a low incidence (<1000/day) of COVID-19 in Japan in the midst of the second and the third waves. Japanese citizens aged ≥20 who had not received any COVID-19 vaccine and did not intend to be vaccinated were randomly assigned to one of the following three groups: (1) a control group, (2) a group using a mobile app chatbot providing information on COVID-19 vaccines and (3) a group using interactive webinars with health professionals. VI and predefined Vaccine Confidence Index (VCI) measuring confidence in the importance, safety and effectiveness were compared before and after the interventions under intention-to-treat principle. Logistic regression models were used to investigate the effect of each intervention on postintervention VI and changes of VCI compared with control. RESULTS Among 386 participants in each group, 359 (93.0%), 231 (59.8%) and 207 (53.6%) completed the postsurvey for the control, chatbot and webinar groups, respectively. The average duration between the intervention and the postsurvey was 32 days in chatbot group and 27 days in webinar group. VI increased from 0% to 18.5% (95% CI 14.5%, 22.5%) in control group, 15.4% (95% CI 10.8%, 20.1%) in chatbot group and 19.7% (95% CI 14.5%, 24.9%) in webinar group without significant difference (OR for improvement=0.8 (95% CI 0.5, 1.3), p=0.33 between chatbot and control, OR=1.1 (95% CI 0.7, 1.6), p=0.73 between webinar and control). VCI change tended to be larger in chatbot group compared with control group without significant difference (3.3% vs -2.5% in importance, OR for improvement=1.3 (95% CI 0.9, 2.0), p=0.18; 2.5% vs 1.9% in safety, OR=1.1 (95% CI 0.7, 1.9), p=0.62; -2.4% vs -7.6% in effectiveness, OR=1.4 (95% CI 0.9, 2.1), p=0.09). Improvement in VCI was larger in webinar group compared with control group for importance (7.8% vs -2.5%, OR=1.8 (95% CI 1.2, 2.8), p<0.01), effectiveness (6.4% vs -7.6%, OR=2.2 (95% CI 1.4, 3.4), p<0.01) and safety (6.0% vs 1.9%, OR=1.6 (95% CI 1.0, 2.6), p=0.08). CONCLUSION This study demonstrated that neither the chatbot nor the webinar changed VI importantly compared with control. Interactive webinars could be an effective tool to change vaccine confidence. Further study is needed to identify risk factors associated with decreased vaccine confidence and investigate what intervention can increase VI and vaccine confidence for COVID-19 vaccines.

Abstract
The worldwide spread of tick-borne diseases (TBDs) has become a public health concern. Therefore, this study aimed to clarify trends in the incidence of Japanese spotted fever (JSF), one of Japan's most prevalent TBDs. Weekly infectious disease reports were used to calculate the annual incidence rates (AIRs) of JSF. Data were stratified by age and sex, and joinpoint regression analysis was performed to estimate the annual percentage change (APC). AIR and APC were geographically compared among the 47 prefectures. A total of 3,453 JSF cases were observed from 2001 to 2020. The AIR per 100,000 population was 0.03 in 2001, which increased approximately 10-fold to 0.33 in 2020. The average APC (AAPC) during the study period was 12.3% (95% CI: 10.7-13.9). By age group, the incidence of JSF increased more rapidly among the older population: 11.5% (95% CI: 10.1-12.9) in those aged ≥ 65 years and 8.9% (95% CI: 6.4-11.5) in those aged < 50 years. Although the AIR over the past two decades was higher in climatically warm regions located in southwestern Japan and on the Pacific coast, increases in the AAPC were notable in colder regions located in eastern Japan. The incidence of JSF continues to increase in Japan, especially among older populations and in eastern prefectures, where the disease has not been previously diagnosed.

Abstract
Malignant mesothelioma (MM) is uncommon in cats and dogs and can be challenging to diagnose. Adequate tissue sampling is required for superior diagnostic accuracy. Protoporphyrin IX, a metabolite of 5-aminolaevulinic acid (5-ALA), is a photosensitiser for photodynamic diagnosis (PDD). To the best of our knowledge, no study has reported the use of 5-ALA-PDD to detect MM in veterinary medicine. The present study describes the use of 5-ALA-PDD for MM diagnosis in a cat and dog, as well as the effectiveness of intracavitary chemotherapy. We evaluated the use of PDD with 5-ALA hydrochloride (5-ALA-PDD) in two cases of MM. A 12-year-old cat presented with a 1-month history of respiratory distress, and a 9-year-old dog presented with a 3-month history of mild abdominal distention. We endoscopically biopsied lesions in both the cases using 5-ALA-PDD. Histopathological examination revealed mesothelioma, and immunohistochemical staining was positive for calretinin. Both patients were treated with carboplatin. The cat died of respiratory failure. Although, the dog's condition improved 21 days after the first chemotherapeutic drug administration, the dog died on day 684 owing to cardiac-related issues. 5-ALA-PDD is thus, safe and feasible for the diagnosis of MM in veterinary medicine.

Abstract
OBJECTIVES A comfortable walking speed is a suitable measurement of functional status in older adults. In addition to assessing their comfortable walking speed, two complex walking tests were administered to a cohort of older people, assuming that these tests would be a more sensitive predictor of the incident long-term care needs than comfortable walking speed. DESIGN A prospective observational study was conducted to collect data. SETTING AND PARTICIPANTS Among the initial 5,563 community-dwelling independent older adults (aged ≥ 65 years), 935 were excluded and the data of 4,628 (mean age, 73.9 ± 5.5 years, 65-94 years; 2,052 men, 2,576 women) older adults were finally analyzed. METHODS Three walking tasks were administered: comfortable, complicated balance, and Go-stop walking. Complicated balance walking was measured under comfortable walking conditions, with participants having to walk with their hands crossed at the shoulder joint at 90°. For the Go-stop walking test, the time taken to walk 2 meters was measured using a stopwatch. For two years following baseline assessments, participants received monthly follow-ups for incident certification of the need for care under the long-term care insurance (LTCI) system. RESULTS Low performance in comfortable, complicated balance, and Go-stop walking were 29.8%, 37.7%, and 35.1%, respectively. During the 24-month follow-up period, 246 participants (5.3%) required LTCI certification. The Youden Index was used to determine the cut-points of the incident long-term care needs in the comfortable, complicated balance, and Go-stop walking conditions, which were 1.055 m/s, 0.936 m/s, and 3.205 seconds, respectively. Participants classified as exhibiting low performance included 1,381 (29.8%) under comfortable walking, 1,746 (37.7%) under complicated balance walking, and 1,623 (35.1%) under the Go-stop walking tests. The C-indices of the comfortable, complicated balance, and Go-stop walking tests were 0.72 (95% confidence interval (CI) 0.69-0.76), 0.71 (95% CI 0.67-0.74), and 0.65 (95% CI 0.61-0.69), respectively. Cox proportional hazards regression model revealed significant relationships between the incident long-term care needs and the comfortable (hazard ratio (HR) 2.14, 95% CI 1.62-2.84), complicated balance (1.81, 1.36-2.41), and Go-stop (1.46, 1.12-1.91) walking conditions. CONCLUSIONS AND IMPLICATIONS The findings suggest that slow walking speed has a considerably greater impact on the incident long-term care needs in older adults. However, the complex walking task did not improve the predictive performance. Comfortable walking speed tests, which can easily be measured to predict the future incident long-term care needs, are effective tools in community health promotion and primary care.

Abstract
Abstract
Background
Little is known about how social media platforms can be used to increase COVID-19 vaccine intent. We aimed to investigate the effect of social media-based interventions on vaccine hesitancy in Japan.
Methods
We conducted a three-arm randomized controlled trial between 5 November 2021 and 9 January 2022. Japanese aged 20 or above who had not received any COVID-19 vaccine and did not intend to be vaccinated were randomly assigned to one of the following three groups: (i) a control group (with no intervention), (ii) a group with a free chatbot in a popular messenger app called ‘LINE,’ which provided general information on COVID-19 vaccines and (iii) a group with free webinars where healthcare professionals interactively provided participants with the information on COVID-19 vaccines. The vaccine intention (VI) and three pre-defined Vaccine Confidence Index (VCI), including the importance, safety, and effectiveness of COVID-19 vaccines, were compared.
Results
1,158 persons were included, and the baseline characteristics and demographics were balanced across three groups (Table 1). Among 386 persons assigned to the chatbot group, 231 (59.8%) accessed the chatbot and answered the post-survey. The post-survey revealed no significant difference in VI or VCI between the chatbot group and the control group (Table 2). Among 386 persons assigned to the webinar group, 207 (53.6%) attended webinars and answered the post-survey. The post-survey revealed no difference in VI between the webinar group and the control group. However, the VCI for the importance and the effectiveness significantly increased in the webinar group. There was no difference in VCI for the safety. VCI for the importance and the effectiveness in the control group decreased without any intervention during the study period.
Vaccine intention and confidence after interventions Table 1Table 2
Conclusion
While this study demonstrated that neither the chatbot nor the webinar changed VI, VCI for the importance and the effectiveness significantly increased with the webinar intervention. Interactive webinars with live Q and A provided by professionals may have a role in increasing COVID-19 vaccine confidence. Given the degree of vaccine hesitancy worsened over time in the control group, timely intervention is required.

Abstract
AIM Amid the global aging, an establishment of healthcare policies for the aged population is a common issue to be addressed. However, few studies on centenarians have reported place and cause of death (PoD and CoD, respectively) as indicators of end-of-life care quality. This study aimed to analyze trends in PoD and CoD among centenarians in Japan. METHODS Data from death certificates from Japanese vital statistics were analyzed; 205 513 deaths occurred among centenarians (aged ≥100 years) in Japan during the period from 2006 to 2016. PoD prevalence was calculated for each CoD. Trends in PoD prevalence were analyzed using the Joinpoint regression model. Changing points, annual percentage changes, and average annual percentage changes (AAPCs) were calculated to examine trends. RESULTS The number of deaths more than doubled from 10 340 in 2006 to 26 427 in 2016. PoDs were composed of hospitals (52.7%), nursing homes (31.4%), own homes (13.6%) and others (2.2%). Dementia and old age increased rapidly as CoD. Proportions of hospital and home deaths decreased, with AAPCs of -2.3% (95% confidence interval [CI], -2.6 to -1.9) and -2.3% (95% CI, -3.2 to -1.4), respectively. Conversely, the proportion of deaths in nursing homes rapidly increased, with an AAPC of 6.8% (95% CI, 6.0-7.7). CONCLUSIONS The results revealed changes in PoD among centenarians in Japan. Understanding these transitions is indispensable for health policy in aging societies. Geriatr Gerontol Int 2022; ••: ••-••.

Abstract
Background There is a long history in Japan of public concerns about vaccine adverse events. Few studies have assessed how mobile messenger apps affect COVID-19 vaccine hesitancy. Methods Corowa-kun, a free chatbot, was created on February 6, 2021 in LINE, the most popular messenger app in Japan. Corowa-kun provides instant, automated answers to 70 frequently asked COVID-19 vaccine questions. A cross-sectional survey with 21 questions was performed within Corowa-kun during April 5–12, 2021. Results A total of 59,676 persons used Corowa-kun during February–April 2021. Of them, 10,192 users (17%) participated in the survey. Median age was 55 years (range 16–97), and most were female (74%). COVID-19 vaccine hesitancy reported by survey respondents decreased from 41% to 20% after using Corowa-kun. Of the 20% who remained hesitant, 16% (1,675) were unsure, and 4% (3 6 4) did not intend to be vaccinated. Factors associated with vaccine hesitancy were: age 16–34 (odds ratio [OR] = 3.7; 95% confidential interval [CI]: 3.0–4.6, compared to age ≥ 65), female sex (OR = 2.4; Cl: 2.1–2.8), and history of a previous vaccine side-effect (OR = 2.5; Cl: 2.2–2.9). Being a physician (OR = 0.2; Cl: 0.1–0.4) and having received a flu vaccine the prior season (OR = 0.4; Cl: 0.3–0.4) were protective. Conclusions A substantial number of people used the chabot in a short period. Mobile messenger apps could be leveraged to provide accurate vaccine information and to investigate vaccine intention and risk factors for vaccine hesitancy.

Abstract
After the acute phase of COVID-19, some patients have been reported to have persistent symptoms including general fatigue. We have established a COVID-19 aftercare clinic (CAC) to provide care for an increasing number of these patients. Here, we report the case of a 36-year-old man who developed post-COVID fatigue after acute infection with SARS-CoV-2. In the acute phase of COVID-19, the patient’s fever resolved within four days; however, general fatigue persisted for three months, and he visited our CAC 99 days after the initial infection. Examination revealed a high Aging Male’s Symptoms (AMS) score of 44 and low free testosterone (FT) level of 5.5 pg/mL, which meet the Japanese criteria of late-onset hypogonadism (LOH) syndrome. Imaging studies revealed an atrophic pituitary in addition to fatty liver and low bone mineral density. Anterior pituitary function tests showed a low follicle-stimulating hormonelevel and delayed reaction of luteinizing hormone (LH) after gonadotropin-releasing hormone (GnRH) stimulation, indicating the possibility of hypothalamic hypogonadism in addition to primary hypogonadism seen in patients with post-COVID-19 conditions. After the initiation of Japanese traditional medicine (Kampo medicine: hochuekkito followed by juzentaihoto), the patient’s symptoms as well as his AMS score and serum FT level were noticeably improved. Furthermore, follow-up tests of GnRH stimulation revealed improvements in LH responsiveness. Although many patients have been reported to meet the criteria of ME/CFS such as our case, we emphasize the possibility of other underlying pathologies including LOH syndrome. In conclusion, LOH syndrome should be considered a cause of general fatigue in patients with post-COVID-19 conditions and herbal treatment might be effective for long COVID symptoms due to LOH (264 words).

Abstract
BACKGROUND The sarcoidosis mortality rate has increased over the years, which contributes to the health care burden. Although epidemiological studies of sarcoidosis mortality in aging societies are essential, none have been published since 1989 in Japan. METHODS We aimed to investigate the trends in crude and age-adjusted sarcoidosis-associated mortality rates per 1,000,000 population in Japan from 2001 to 2020 using national death certificate data among older adults aged over 50 years. The data were analysed using the joinpoint regression models to estimate long-term trends and average annual percentage changes (AAPCs). RESULTS A total of 3094 sarcoidosis-associated deaths were recorded from 2001 to 2020 in Japan; women constituted 65.3% of these, with a female:male ratio of 1.89. Nearly 80% of deaths were over the age of 65 years, of which 32% were over the age of 80 years. The trend in crude mortality of those aged ≥80 years markedly increased from 0.81 to 9.68 per 1,000,000 population in men and from 2.38 to 12.87 in women, respectively. The overall age-adjusted sarcoidosis mortality rate increased 2.46-fold during the study period, with an AAPC of 5.1%. CONCLUSIONS This study revealed that sarcoidosis-associated deaths in Japan have significantly increased over the past two decades, especially among the older population with a female predominance. Given the rising mortality rate and susceptibility of the older population, sarcoidosis will require more attention from health care providers in terms of a multidisciplinary approach to address the specific needs of the older population.

Abstract
OBJECTIVES Recently, the standard of care for advanced urothelial cancer (UC) has been changed by developing immune-checkpoint inhibitors (ICIs). However, its response rate is limited to 20-30%. The identification of biomarkers to predict the therapeutic effects of ICIs is urgently needed. The present study explored the association between immunohistochemical biomarkers and clinical outcomes in UC patients treated with pembrolizumab. PATIENTS AND METHODS A total of 85 patients with UC who received pembrolizumab after chemotherapy from January 2018 to May 2020 were retrospectively reviewed. Tumor tissues were obtained for immunohistochemical study from 47 out of 85 patients. The protein expressions of PD-L1, WT1, Nectin-4, CD4, CD8, Foxp3, and CD68 in tumor cells and/or tumor infiltrating lymphocytes were immunohistochemically examined. The associations between protein expressions and overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) were statistically analyzed. RESULTS Patients with positive PD-L1 in tumor cells showed significantly worse OS (Log-rank test: HR 5.146, p = 0.001, Cox regression analysis: HR 4.331, p = 0.014) and PFS (Log-rank test: HR 3.31. p = 0.022), along with significantly lower DCR (14.3%) compared to the PD-L1 negative patients (67.5%). In addition, patients with strong expression of Nectin-4 in tumor cells showed significantly higher DCR (100%) than the other patients (50%). CONCLUSION PD-L1 expression in tumor cells was associated with poor prognosis (OS and PFS) and low DCR. Interestingly, the strong expression of Nectin-4 was correlated with high DCR. PD-L1 and Nectin-4 expression in tumor cells could be prognostic biomarkers useful for pembrolizumab in patients with advanced UC.

Abstract
AIM Despite the increasing attention that has been paid to amyloidosis in recent years, there have been few reports on amyloidosis mortality and its trends worldwide. This study aimed to evaluate the trends in crude and age-adjusted amyloidosis-associated mortality rates in Japan from 1998 to 2019. METHODS We used national Vital Statistics data among older adults aged over 50 years. The data were analyzed using the joinpoint regression program to estimate the long-term trends and average annual percentage changes (AAPCs). RESULTS A total of 9158 amyloidosis-associated deaths were recorded from 1998 to 2019, of which 56.1% were in men. The crude mortality rate per 1 000 000 older adults aged over 80 years increased from 9.65 to 54.3 among men and from 7.02 to 22.1 among women during the study period. Overall, the AAPCs of age-adjusted amyloidosis-associated mortality rates increased significantly over the study period (1.8%, 95% confidence interval [CI], 1.0-2.7%). While the annual percentage change (APC) of age-adjusted mortality rates in women showed no significant change over the study period, the APC in men markedly increased in the 2013-2019 period (8.2%, 95% CI: 6.0-10.4%). CONCLUSIONS This study revealed an increasing trend in mortality associated with amyloidosis, and in particular a marked increase in mortality among men over the past 6 years. Considering its high mortality rate and susceptibility to the effects of an increasing population of older adults, amyloidosis deserves more attention from healthcare providers to improve the understanding of diagnosis, clinical treatment, and healthcare planning.

Abstract
BACKGROUND Several technical devices are available to monitor and promote changes in behavior toward higher activity. In particular, smartphones are becoming the primary platform for recognizing human activity. However, the effects of behavior change techniques that promote physical, cognitive, and social activities on incident dementia in older adults remain unknown. OBJECTIVES This randomized controlled trial aims to examine the effects of behavior change techniques on the prevention of dementia among community-dwelling older adults using a smartphone as a behavior change tool. DESIGN A randomized controlled trial. SETTING Community in Japan. PARTICIPANTS The study cohort comprises 3,498 individuals, aged ≥60 years, randomized into two groups: the smartphone group (n = 1,749) and the control group (n = 1,749). INTERVENTION The smartphone group will be asked to use smartphone applications for at least 30 minutes daily to self-manage and improve their physical, cognitive, and social activities. The smartphone group will perform 60-minute group walking sessions using application-linked Nordic walking poles with cognitive stimulation twice a week during the intervention period. The walking poles are a dual-task exercise tool that works with a smartphone to perform cognitive tasks while walking, and the poles are equipped with switches to answer questions for simple calculation and memory tasks. The smartphone and control groups will receive lectures about general health that will be provided during the baseline and follow-up assessments. MEASUREMENTS Incident dementia will be detected using cognitive tests (at baseline, after 15 months, and after 30 months) and by preparing diagnostic monthly reports based on data from the Japanese Health Insurance System. Participants without dementia at baseline who will be diagnosed with dementia over the 30-month follow-up period will be considered to have incident dementia. CONCLUSIONS This study has the potential to provide the first evidence of the effectiveness of information communication technology and Internet of Things in incident dementia. If our trial results show a delayed dementia onset for self-determination interventions, the study protocol will provide a cost-effective and safe method for maintaining healthy cognitive aging.

Abstract
OBJECTIVES Physical activity is recommended for disability prevention in the older adult population; however, the level of physical activity required for older adults with chronic kidney disease (CKD) remains unknown. This study aimed to examine the associations between daily physical activity and disability incidence in older adults with and without CKD to determine relevant daily physical activity levels. DESIGN Prospective observational study. SETTING AND PARTICIPANTS 3,786 community-dwelling older adults aged ≥65 years. MEASUREMENTS Mean daily times spent in light- (LPA) and moderate-to-vigorous physical activity (MVPA) were measured using triaxial accelerometers. CKD was defined by a creatinine estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Disability incidence was identified as long-term care insurance certification during a 60-month follow-up period. Associations between physical activity and disability incidence were examined using Cox proportional hazard models stratified by the CKD status. Non-linear and linear associations were tested using the restricted cubic spline. RESULTS A total of 1,054 individuals were identified to have CKD. Disability incidence was higher in the CKD group than in the non-CKD group. The adjusted cox proportional hazard models indicated that a 10-minute increase in MVPA time was associated with lower disability incidence in the non-CKD group (hazard ratio [HR], 0.838; 95% confidence interval [CI]: 0.764-0.918) and the CKD group (HR, 0.859; 95% CI: 0.766-0.960). Linear associations were observed in MVPA for the non-CKD and CKD groups. CONCLUSION Increasing MVPA was associated with lower disability incidence in older adults with and without CKD. These findings can help devise disability prevention strategies for older CKD patients.

Abstract
OBJECTIVES This observational prospective cohort study, conducted between September 2015 and February 2019, aimed to investigate the association between the incidence of disability and non-face-to-face interactions among community-dwelling older adults in Japan. DESIGN Participants reported their interaction status using a self-report questionnaire. Face-to-face interactions comprised in-person meetings, while virtual interactions (e.g., via phone calls or emails) were defined as non-face-to-face interactions. We examined the relationship between their interaction status at baseline and the risk of disability incidence at follow-up. We also considered several potential confounding variables, such as demographic characteristics. SETTING The National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes. PARTICIPANTS We included 1159 adults from Takahama City aged ≥75 years (mean age ± standard deviation = 79.5 ± 3.6 years). MEASUREMENTS Interaction status was assessed using a self-reported questionnaire consisting of two sections (face-to-face and non-face-to-face interactions), and four questionnaire items. Based on the responses we categorized study participants into four groups: "both interactions," "face-to-face only," "non-face-to-face only," and "no interactions." RESULTS Individuals with both kinds of interactions (49.3/1000 person-years) or only one kind of interaction (face-to-face = 57.7/1000 person-years; non-face-to-face = 41.2 person-years) had lower incidence of disability than those with no interactions (88.9/1000 person-years). Moreover, the hazard ratios adjusted for potential confounding factors for the incidence of disability in the both interaction, face-to-face-only, and non-face-to-face only groups were 0.57 (confidence interval = 0.39-0.82; p = 0.003), 0.66 (confidence interval = 0.44-0.98; p = 0.038), and 0.47 (confidence interval = 0.22-0.99; p = 0.048), respectively. CONCLUSION Considering the interaction status of older adults in their day-to-day practice, clinicians may be able to achieve better outcomes in the primary prevention of disease by encouraging older adults to engage in any form of interaction, including non-face-to-face interactions.

Abstract
Background Japan has one of the highest vaccine hesitancy rates in the world. According to a previous study, less than 30% of people strongly agreed that vaccines were safe, important, or effective. We created a COVID-19 vaccine information chatbot in a popular messenger app in Japan to answer COVID-19 vaccine frequently asked questions (FAQs) via text messages. We assessed the impact of chatbot text messages on COVID-19 vaccine hesitancy by conducting a cross-sectional survey among chatbot users. Methods LINE is the most popular messenger app in Japan; about 86 million people in Japan (roughly two-thirds of the population) use this messenger app. Corowa-kun, a free chatbot, was created in LINE on February 6, 2021. Corowa-kun provides instant, automated answers to frequently asked COVID-19 vaccine questions. A cross-sectional survey assessing COVID-19 vaccine hesitancy was conducted via Corowa-kun during April 5 to 12, 2021. We included persons ages 16 years old and older who had not received a COVID-19 vaccine. The survey was written in Japanese and consisted of 21 questions. Corowa-kun’s Consultation Room ![]()
Corowa-kun is the mascot of an online chatbot. This chatbot in LINE is used to answer COVID-19 vaccine frequently asked questions (FAQs) via text messages. As of May 10th, 70 FAQs are available. Results A total of 59,676 persons used Corowa-kun during February to April 2021. The most commonly accessed message categories were: “I have (select comorbidity), can I get a COVID-19 vaccine?” (23%); followed by questions on adverse reactions (22%) and how the vaccine works (20%). 10,192 users (17%) participated in the survey. Median age was 55 years (range 16 to 97), and most were female (74%). Intention to receive a COVID-19 vaccine increased from 59% to 80% after using Corowa-kun (p < 0.01). Overall, 20% remained hesitant: 16% (1,675) were unsure, and 4% (364) did not intend to be vaccinated. Factors associated with vaccine hesitancy were: age 16 to 34 (odds ratio [OR] = 3.7, 95% confidential interval [CI]: 3.0–4.6, compared to age ≥65), female sex (OR = 2.4, Cl: 2.1–2.8), and history of another vaccine side-effect (OR = 2.5, Cl: 2.2–2.9). Being a physician (OR = 0.2, Cl: 0.1-0.4) and having received a flu vaccine the prior season (OR = 0.4, Cl: 0.3-0.4) were protective. COVID-19 vaccine acceptance increased and hesitancy decreased after using Corowa-kun, Japan, 2021 (n=10,192) ![]()
*There was a statistically significant difference in responses between before and after using Corowa-kun (p < 0.01, Chi-square test). Univariable logistic regression models of factors associated with COVID-19 vaccine hesitancy, Japan, 2021 (n=10,192) ![]()
Ref: reference NA: Logistic regression was not performed due to too small number (n≤3) Conclusion Corowa-kun reduced vaccine hesitancy by providing COVID-19 vaccine information in a messenger app. Mobile messenger apps could be leveraged to increase COVID-19 vaccine acceptance.

Abstract
In two-dimensional (2D) NbSe2 crystal, which lacks inversion symmetry, strong spin-orbit coupling aligns the spins of Cooper pairs to the orbital valleys, forming Ising Cooper pairs (ICPs). The unusual spin texture of ICPs can be further modulated by introducing magnetic exchange. Here, we report unconventional supercurrent phase in van der Waals heterostructure Josephson junctions (JJs) that couples NbSe2 ICPs across an atomically thin magnetic insulator (MI) Cr2Ge2Te6. By constructing a superconducting quantum interference device (SQUID), we measure the phase of the transferred Cooper pairs in the MI JJ. We demonstrate a doubly degenerate nontrivial JJ phase (ϕ), formed by momentum-conserving tunneling of ICPs across magnetic domains in the barrier. The doubly degenerate ground states in MI JJs provide a two-level quantum system that can be utilized as a new dissipationless component for superconducting quantum devices. Our work boosts the study of various superconducting states with spin-orbit coupling, opening up an avenue to designing new superconducting phase-controlled quantum electronic devices. Van der Waals structures provide a new platform to explore novel physics of superconductor/ferromagnet interfaces. Here, NbSe2 Josephson junction with Cr2Ge2Te6 enables non-trivial Josephson phase by spin-dependent interaction, boosting the study of superconducting states with spin-orbit coupling and phase-controlled quantum electronic device.

Abstract
Background Nivolumab (NIVO) and irinotecan (IRI) are standard treatments for refractory advanced gastric cancer (AGC); however, it is unclear which drug should be administered first or in which cases. The tumor growth rate (TGR) during preceding treatment is reported to be associated with tumor response in metastatic colorectal cancer patients treated with regorafenib or trifluridine/tipiracil, suggesting that TGR may be useful for drug selection. Therefore, we evaluated the association between TGR during preceding treatment and the tumor response to NIVO or IRI. Patients and methods We retrospectively evaluated consecutive AGC patients treated with NIVO or IRI and divided them into slow-growing (Slow) and rapid-growing (Rapid) groups according to TGR and the presence or absence of new lesions (NL+/NL−, respectively) during preceding treatment (Slow group: NL− with low TGR <0.30%/day; Rapid group: NL+ or high TGR ≥0.30%/day). Results A total of 117 patients (Rapid/Slow groups, 72/45; NIVO/IRI groups, 32/85) were eligible. All baseline characteristics except peritoneal metastases were similar between patients treated with NIVO and IRI in the Rapid and Slow groups. The response rate was significantly higher in patients treated with NIVO compared with IRI [31%/3%; odds ratio (OR), 13.8; P = 0.01; adjusted OR, 52; P = 0.002] in the Slow group, but there was no difference between patients treated with NIVO and IRI (5%/8%; OR, 0.68; P = 0.73; adjusted OR, 0.94; P = 0.96) in the Rapid group. Disease control rate, progression-free survival, and overall survival were consistent with these results. Conclusions Our findings suggest that NIVO treatment is a more favorable option for patients with slow-growing tumors, and NIVO and IRI are similarly recommended for patients with rapid-growing tumors in refractory AGC. TGR and NL emergence during preceding treatment may be helpful for drug selection and warrant further investigation. NIVO and IRI are standard treatments for refractory AGC, although it is unclear which should be administered first. TGR may be useful for drug selection, therefore we evaluated the association between TGR and the tumor response to NIVO or IRI. In the Slow group, the response rate (RR) was significantly higher in patients treated with NIVO compared with IRI. In the Rapid group, there was no significant difference in RR between the NIVO and IRI groups. TGR and NL emergence during preceding treatment may be useful for drug selection.

Abstract
Migration Stimulating Factor (MSF) is a 70 kDa truncated isoform of fibronectin (FN); its mRNA is generated from the FN gene by an unusual two-stage processing. Unlike full-length FN, MSF is not a matrix molecule but a soluble protein which displays cytokine-like activities not displayed by any other FN isoform due to steric hindrance. There are two isoforms of MSF; these are referred to as MSF+aa and MSF-aa, while the term MSF is used to include both.MSF was first identified as a motogen secreted by foetal and cancer-associated fibroblasts in tissue culture. It is also produced by sprouting (angiogenic) endothelial cells, tumour cells and activated macrophages. Keratinocytes and resting endothelial cells secrete inhibitors of MSF that have been identified as NGAL and IGFBP-7, respectively. MSF+aa and MSF-aa show distinct functionality in that only MSF+aa is inhibited by NGAL.MSF is present in 70-80% of all tumours examined, expressed by the tumour cells as well as by fibroblasts, endothelial cells and macrophages in the tumour microenvironment (TME). High MSF expression is associated with tumour progression and poor prognosis in all tumours examined, including breast carcinomas, non-small cell lung cancer (NSCLC), salivary gland tumours (SGT) and oral squamous cell carcinomas (OSCC). Epithelial and stromal MSF carry independent prognostic value. MSF is also expressed systemically in cancer patients, being detected in serum and produced by fibroblast from distal uninvolved skin. MSF-aa is the main isoform associated with cancer, whereas MSF+aa may be expressed by both normal and malignant tissues.The expression of MSF is not invariant; it may be switched on and off in a reversible manner, which requires precise interactions between soluble factors present in the TME and the extracellular matrix in contact with the cells. MSF expression in fibroblasts may be switched on by a transient exposure to several molecules, including TGFβ1 and MSF itself, indicating an auto-inductive capacity.Acting by both paracrine and autocrine mechanisms, MSF stimulates cell migration/invasion, induces angiogenesis and cell differentiation and alters the matrix and cellular composition of the TME. MSF is also a survival factor for sprouting endothelial cells. IGD tri- and tetra-peptides mimic the motogenic and angiogenic activities of MSF, with both molecules inhibiting AKT activity and requiring αvβ3 functionality. MSF is active at unprecedently low concentrations in a manner which is target cell specific. Thus, different bioactive motifs and extracellular matrix requirements apply to fibroblasts, endothelial cells and tumour cells. Unlike other motogenic and angiogenic factors, MSF does not affect cell proliferation but it stimulates tumour growth through its angiogenic effect and downstream mechanisms.The epithelial-stromal pattern of expression and range of bioactivities displayed puts MSF in the unique position of potentially promoting tumour progression from both the "seed" and the "soil" perspectives.

Abstract
OBJECTIVE Insulin-like growth factor-1 (IGF-1) is an anabolic hormone, the levels of which decline with age. The present study aimed to determine the impact of age-related declines in serum IGF-1 levels on various physiological processes. DESIGN We retrospectively reviewed the medical records of patients whose serum IGF-1 levels were estimated in our department, and assessed the relationships between serum IGF-1 levels and various physiological parameters. RESULTS A total of 427 patients with a mean (± standard deviation) age of 52.8 (± 17.1) years were included in the analysis. The levels of serum IGF-1 showed significant positive correlation with those of hemoglobin and hematocrit, and negative correlation with the presence of inflammatory and fibrin-related markers including C-reactive protein (CRP) and procalcitonin (PCT), and D-dimer and fibrin degradation products (FDP). These tendencies persisted after exclusion of patients with pituitary disease. CONCLUSIONS In this study population of diverse diseases and backgrounds, a decline in serum IGF-1 levels with age was associated with an increase in inflammatory and fibrin-related markers. This may explain the correlation between low serum IGF-1 levels and an increased risk of cardiovascular events. Our findings suggest that serum IGF-1 is a clinically relevant marker of cardiovascular risk, particularly in males.

Abstract
PURPOSE The aim of the present study was to determine how age-related decreases in serum dehydroepiandrosterone sulfate (DHEAS) levels affect various physiological processes. METHODS We retrospectively reviewed the medical records of patients in whom serum DHEAS levels were measured in our department and assessed the relationships between serum DHEAS levels and various patient characteristics. RESULTS Among the 149 patients included in our analysis (mean age: 52.7 ± 17.6 years, range: 15-84 years), 54 (36.2%) were men. Serum DHEAS levels inversely correlated with age in men (R = -0.810, p < .01) and to a lesser extent in women (R = -0.391, p < .01). Of note, there were significant positive associations between DHEAS levels and hemoglobin (R = 0.317, p ≤ .01) and hematocrit (R = 0.324, p ≤ .01) levels, which were observed in men, but not in women. CONCLUSIONS Our study suggests that reduced DHEAS secretion inhibits erythropoietic activity in aging men, perhaps owing to the erythropoietic androgenic actions of DHEAS. Importantly, it suggests that the age-associated decline in DHEAS secretion might decrease erythropoietic activity in aging men. It is also possible that the adrenal cortex, the source of DHEAS, is dysfunctional in anemic men.

Abstract
Introduction
Several report showed the association between ambient air pollution including particular matter under 2.5um (PM2.5) and increasing rate of hospitalization for heart failure. However, these report analyzed mainly cross-sectional, epidemiological data, thus the reports regarding association between vulnerability to PM2.5 and specific populations in acute heart failure (AHF) were scarce.
Purpose
1. To analyze the association between air pollution and rate of hospitalization for AHF
2. To analyze whether the vulnerability to air pollution differ between specific populations in AHF. Methods
A case-cross over analysis was conducted to 4980 consecutive patients registered for multicenter acute heart failure registry in 2017 in our city Japan. This registry enrolled patients transferred to cardiovascular care unit (80 institutions) via emergency medical services across our city area. Logistic regression analysis were conducted to estimate percentage changes in the rate of acute heart failure hospitalization associated with per 1μg/m3 PM2.5 concentration increase. We also conducted subgroup analysis for patients stratified by age, gender, comorbidities, left ventricular ejection fraction, and clinical scenario.
Results
An increase in 1 μg/m3 PM2.5 concentration corresponded to 2.9% (95% CI 1.2–4.6%) increase in AHF hospitalization. Patients with age younger than 75, without prior heart failure hospitalization, without history of hypertension, without anemia, and with reduced ejection fraction were more susceptible to increase in PM2.5 concentration (Figure).
Conclusions
Increase in PM2.5 concentration was associated with increased rate of AHF hospitalization. Effect of PM2.5 may differ across specific AHF subpopulations.

Abstract
In the era of hyper-ageing, Creutzfeldt-Jakob disease (CJD) can become more prevalent as an important cause of dementia. This study aimed to evaluate the trends in crude and age-adjusted CJD-associated mortality and incidence rates in Japan using national vital statistics data on CJD-associated deaths among individuals aged over 50 years, as well as the government-funded nationwide CJD surveillance data (pertaining to the years 2005-2014) in Japan. The data were analysed using the Joinpoint Regression Program to estimate the long-term trends and average annual percentage changes (AAPCs). Overall, the AAPCs of age-adjusted CJD-associated mortality rates rose significantly over the study period (3.2%; 95% confidence interval [CI] 1.4-5.1%). The AAPC of the age-adjusted incidence rates also increased (overall 6.4%; 95% CI 4.7-8.1%). The CJD-associated increases in the mortality and incidence rates were especially prominent among adults over the age of 70 years. Given this trend in aging of population, the disease burden of CJD will continue to increase in severity. Our findings thus recommend that policymakers be aware of the importance of CJD and focus on preparing to address the increasing prevalence of dementia.

Abstract
Adrenocortical carcinoma (ACC) is a rare aggressive tumor originating from adrenocortical parenchymal cells and its incidence is approximately 1 per million population per year. An oncocytic ACC is a recently identified entity among the several known histopathological variants of ACC, which is characterized by oncocytic cells, and only a few cases in the available literature have reported this tumor. In contrast to conventional ACCs, oncocytic ACCs usually manifest as solitary lesions presenting in adults without any sex predilection. We report a case of a 70-year-old Japanese man who presented with an incidentally discovered retroperitoneal mass without any evidence of excessive corticosteroid secretion. Laboratory and imaging studies, as well as transgastric endoscopic ultrasound-guided fine needle aspiration failed to establish a definitive diagnosis. Thus, the patient underwent surgical resection of the left-sided peritoneal tumor. Weiss score was positive in 6/9 points and the tumor met two major criteria of the Lin-Weiss-Bisceglia (LWB) system leading to a diagnosis of an oncocytic variant of ACC. Based on our findings in this patient, we conclude that a combination of the Weiss and LWB criteria is required to determine the malignant potential of oncocytic adrenal tumors because ACCs and oncocytomas could be frequently indistinguishable. Careful histopathological examination is pivotal in confirming the oncocytic component in the lesion and hence definitive diagnosis of ACCs.

Abstract
Adrenal insufficiency patients are treated with glucocorticoid replacement therapy. However, mimicking the in vivo circadian rhythm of cortisol levels is challenging, and suboptimal replacement increases the risk of mortality from cardiovascular disease. We herein report a case of coronary spastic angina (CSA) with simultaneous low early-morning serum cortisol levels in a patient undergoing corticosteroid replacement therapy for primary adrenal insufficiency. Steroid therapy is reportedly effective for refractory angina, but underlying adrenal deficiency has never been revealed. Our case intimates the probable risk of CSA as a complication of relative adrenal insufficiency and highlights the effectiveness of dexamethasone in these patients.
