Abstract
PURPOSE To investigate the association between comorbidities associated with diabetes and higher-level functional status as well as the relationship between comorbidities associated with diabetes and higher-level functional status in older patients with type 2 diabetes mellitus who have better social networks. METHODS Participants were outpatients with type 2 diabetes aged ≥ 65 years, excluding individuals with severe cardiovascular or respiratory illness, hyperglycaemic crisis, type 1 diabetes, or diabetic foot. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) was used to evaluate the higher-level functional status. A TMIG-IC score of ≤ 9, instrumental activities of daily living (IADL) ≤ 4, intellectual activity or social role ≤ 3 were defined as decline in higher-level functional status. The comorbidities investigated included peripheral neuropathy, retinopathy, nephropathy, cognitive impairment, depression, frailty, sarcopenia, low muscle strength, stroke, heart disease, and arthritis. RESULTS The analysis included 198 patients (mean age 75.9 ± 5.7 years, male 60.1%). After adjusting for potential confounders, depression was associated with TMIG-IC (Prevalence ratio (PR) 2.34, 95% confidence interval (CI) 1.44-3.82), low muscle strength was associated with IADL (PR 2.85, 95% CI 1.30-6.27), and frailty was associated with intellectual activity (PR 1.38, 95% CI 1.10-1.74). In the model with social networks added as a confounder, the relationship between depression or low muscle strength and higher-level functional status was not statistically significant. CONCLUSION Comorbidities of depression and low muscle strength for older patients with type 2 diabetes mellitus increase the risk of malfunctioning of higher-level functional status. Increased interactions with family, friends and neighbours may reduce this event.

Abstract
[Purpose] This study aimed to determine the relationship between acceleration parameters in the sit-to-stand (STS) movement and falls, and the strength of the association between acceleration in STS movements and falls in older adults. [Participants and Methods] In total, 330 older adults were included. Four acceleration parameters were measured in STS movement: maximum acceleration (MA), velocity (MV), power (MP), and stand-up time (ST). For the conventional STS tests, 5 times STS test (5xSTS) and ground reaction force (maximal rate of force development per body weight: RFD/w, peak reaction force per body weight: F/w, chair-rise time: T) were measured. Poisson regression analysis adjusted for confounding factors was used. [Results] In the model adjusted for confounders, significant associations were observed among MV (Prevalence ratio (PR): 0.75; 95% confidence interval (CI): 0.58-0.98), MP (PR: 0.67; 95% Cl: 0.68-0.93), RFD/w (PR: 0.70; 95% Cl: 0.56-0.87), and T (PR: 1.14; 95% Cl: 1.05-1.24). [Conclusion] Among the acceleration parameters, MP was most strongly associated with falls and was considered the most useful parameter for evaluation. In addition, comparisons with the conventional chair rise tests suggested that MP was stronger than the 5xSTS test and may be equally related to the RFD/w.

Abstract
Acceleration parameters in sit-to-stand (STS) movements are useful for measuring lower-limb function in older adults. The purpose of this study was to examine the relationship between acceleration in STS movements and physical function and the test-retest reliability of acceleration parameters in older adults. We performed cross-sectional analyses on 244 older adults including 107 men (mean age: 77.4 ± 4.7) and 137 women (mean age: 75.6 ± 5.3). Four acceleration parameters were measured in STS movements: maximum acceleration (MA), maximum velocity (MV), maximum power (MP), and stand-up time (ST). Good intraclass correlation coefficients (ICC > 0.70) were observed for all parameters. For the acceleration parameters, MA, MV, and MP were relatively strongly associated with the 5-time STS test (men: r = -0.36~-0.47; women: r = -0.37~-0.45) and the timed up and go test (men: r = -0.39~0.47, women: r = -0.43~-0.51): MP was also strongly associated with grip strength (men: r = 0.48, women: r = 0.43). All acceleration parameters were poorer in participants reporting mobility limitations than in those reporting no mobility limitations. These findings support the usefulness of sensor-based STS measurement. The system is expected to be useful in various settings where care prevention is addressed.

Abstract
BACKGROUND/AIM Diffuse-type gastric cancer (GC) frequently exhibits peritoneal metastasis, leading to poor prognosis. However, efforts to develop antitumor strategies for preventing the peritoneal metastasis of GC have been unsuccessful. As diffuse-type GC cells often carry a genetic alteration in the tumor suppressor p53 gene, p53 restoration may be a potent strategy for preventing peritoneal metastasis of GC. In this study, we investigated the therapeutic potential of p53-expressing adenoviral vectors against peritoneal metastasis of diffuse-type GC cells. MATERIALS AND METHODS Three diffuse-type human GC cell types with different p53 statuses (p53-wild type NUGC-4, p53-mutant type GCIY, and p53-null type KATOIII) were used to evaluate the therapeutic potential of p53 activation induced by the p53-expressing, replication-deficient adenovirus Ad-p53 and oncolytic adenovirus OBP-702. Viability, apoptosis, and autophagy of virus-treated GC cells were analyzed under normal and sphere-forming culture conditions using the XTT assay and western blot analysis. The in vivo antitumor effects of OBP-702 and Ad-p53 were assessed using xenograft tumor models involving peritoneal metastasis of NUGC-4 and GCIY cells. RESULTS Under normal and sphere-forming culture conditions, OBP-702 induced a significantly greater antitumor effect in GC cells compared with Ad-p53 by strongly inducing p53-mediated apoptosis and autophagy and receptor tyrosine kinase suppression. In vivo experiments demonstrated that intraperitoneal administration of OBP-702 significantly suppressed the peritoneal metastasis of NUGC-4 and GCIY cells compared with Ad-p53, leading to prolonged survival of mice. CONCLUSION Intraperitoneal administration of OBP-702 inhibits the peritoneal metastasis of GC cells by inducing p53-mediated cytopathic activity.

Abstract
OBJECTIVES This study aimed to investigate the association between whole-body (WB), arm, and leg extracellular-to-intracellular water resistance (Recw/Ricw) ratios and various physical functions of each segment and muscle mass using segmental multifrequency bioelectrical impedance analysis. METHODS In total, 988 community-dwelling older adults were included in the analysis. Physical function was assessed using hand grip, 5-repetition sit-to-stand, 5-m habitual walk, Timed Up and Go, and single-leg balance with eyes open tests. Each segmental Recw/Ricw ratio and muscle mass were assessed at 5 and 250 kHz resistances using a segmental multifrequency bioelectrical impedance analysis device. Pearson's correlation between the segmental Recw/Ricw ratio and muscle mass and physical function was calculated, and the difference in correlation coefficients was tested using Bonferroni correction. Multiple linear regression analysis was conducted using physical function as the dependent variable and the segmental Recw/Ricw ratio as the independent variable, adjusting for sex, age, body mass index, and segmental muscle mass. RESULTS WB and leg Recw/Ricw ratios were significantly positively correlated with good hand grip performance, gait speed, mobility, balance, and standing power (p < 0.05), after adjusting for sex, age, body mass index, and muscle mass. Furthermore, the leg Recw/Ricw ratio was positively associated with lower extremity physical function compared with WB and arm Recw/Ricw ratios and muscle mass (p < 0.01). Conversely, WB muscle mass was more strongly related to grip strength than WB, arm, and leg Recw/Ricw ratios (p < 0.01). CONCLUSIONS The Recw/Ricw ratio is useful for identifying older adults with worse physical function. The Recw/Ricw ratio allows for easy and timely screening of older adults with worse physical function in clinical settings.

Abstract
The Japanese population has the world's longest life expectancy but faces the challenge of extending the healthy life expectancy without developing chronic diseases. Therefore, the effectiveness of products derived from olives used in the Mediterranean diet as a potential dietary solution has attracted attention. This study examined the effects of desert olive tree pearls (DOTPs), which contain 162 times more polyphenol hydroxytyrosol than olive oil, on the cognitive function of middle-aged and older adults using the Cognitrax test. Participants (aged 51-82 years) were assigned to the DOTP intake (n = 36) or placebo group (n = 36) in a randomized, double-blind, placebo-controlled, parallel-group study. The participants received 3 g of DOTPs or placebo in olive oil twice daily for 12 weeks. Among cognitive domains, complex attention had a significant time × group interaction effect (p = 0.049) between the DOTP and placebo groups. The simple main effect for this item was significantly different (p < 0.001 and p = 0.572, respectively). Time effects were significant (p < 0.05) for the psychomotor speed, reaction time, cognitive flexibility, processing speed, and executive function domains. Therefore, DOTPs have the potential to alleviate cognitive problems faced by middle-aged and older adults in Japan.

Abstract
Core body temperature (CBT) shows a diurnal rhythm, and the nocturnal decrease in CBT is blunted in older people. The physiological mechanisms responsible for the blunted nocturnal decrease in CBT in older people remain to be revealed. The aim of this study was to compare heat production and heat dissipation in young and old subjects during sleep, as assessed by indirect calorimetry and the distal-proximal temperature gradient (DPG) of skin temperature. A complete dataset of 9 young (23.3 ± 1.1 years) and 8 old (72.1 ± 2.5 years) females was analyzed. CBT and energy metabolism were monitored during sleep using an ingestible temperature sensor in a metabolic chamber maintained at 25 °C. Skin temperature was measured at proximal and distal parts of the body. CBT, distal skin temperature, and DPG in older subjects were higher than in young subjects. Protein oxidation was similar between the two groups, but fat oxidation was lower and carbohydrate oxidation was higher in old subjects compared to young subjects. On the other hand, energy expenditure was similar between the two age groups. Thus, the elevated CBT in older subjects was not attributed to deteriorated heat dissipation or enhanced heat production, suggesting an alternative explanation such as deteriorated evaporative heat loss in old subjects.

Abstract
BACKGROUND Phase angle (PhA) is an indicator of cellular conditions. Recent studies have suggested that PhA supports healthy aging. Identifying modifiable lifestyle factors for PhA is important. The associations of PhA in 24-h movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, have not been studied in older adults. OBJECTIVES We investigated the cross-sectional associations between 24-h movement behaviors and PhA in community-dwelling older adults while appropriately considering the co-dependent nature of daily time use using compositional data analysis. METHODS The participants were 113 healthy older adults. PhA was measured using a bioelectrical impedance device. Time spent in light-intensity PA (LPA), moderate- to vigorous-intensity PA (MVPA), and SB was measured using a tri-axial accelerometer. Sleep duration information was self-reported in a questionnaire. Compositional multiple linear regression and compositional isotemporal substitution were performed to examine the associations of 24-h movement behaviors with PhA and hypothetical time reallocation in movement behaviors with PhA, respectively. RESULTS Even after adjusting for potential confounders, relative to other behaviors more time spent in MVPA was significantly associated with higher PhA (p < 0.001). The 30 min/day of time reallocation from the other behaviors (SB, LPA, and sleep) to MVPA was predicted to be 0.12 higher PhA (corresponding to 2.3% increase; 95% CI 0.01, 0.24). CONCLUSIONS Our results suggest that increasing or maintaining the daily time spent in MVPA is important for managing PhA in older adults, regardless of the other behaviors time consumed instead.

Abstract
BACKGROUND The relationship between manual dexterity and cognitive function among older adults is well known; however, few studies have focused on manual dexterity training that confirms cognitive load of training in older adults through functional near-infrared spectroscopy (fNIRS) and verifies the effect of training. This study examined the effects of home-based manual dexterity training on cognitive function in older adults using a digital trail-making peg test device combining two conventional assessment tools namely, the peg and trail-making tests. METHODS For 12 weeks, 57 healthy older adults aged 65-88 years participated in a parallel-group, randomized controlled trial, wherein home-based manual dexterity training was performed for approximately 20 min daily. To quantify the cognitive load in different manual dexterity conditions, we assessed the cortical activation patterns of the prefrontal cortex via a wearable four-channel fNIRS device. Participants in the control group were asked to continue their usual daily routines during the intervention period. Cognitive function was assessed using the Stroop Color and Word and Cognitive Impairment Tests. Manual dexterity was assessed using the Purdue Pegboard Test. All outcomes were estimated before and after the intervention. RESULTS We observed significant differences in prefrontal cortical activation between the different manual dexterity conditions. Only the intervention group showed a significant improvement in Stroop interference (169.0-108.9 ms, p = 0.032) and an executive function and assembly task of the Purdue Pegboard Test (22.5-26.4 counts, p < 0.001). Additionally, except the clock drawing task, cognitive function had a larger effect size (Cohen's d) in the intervention group (d = 0.26-0.45) than in the control group (d = 0.11-0.28). CONCLUSIONS Home-based manual dexterity training can improve performance in a complex manual dexterity task and executive functioning in older adults.

Abstract
Because obesity is associated with impaired glucose tolerance and type 2 diabetes (T2D), it is important to manage the blood glucose level at an early stage. Nevertheless, people with obesity have significantly lower resistance to muscle fatigue after exercise and exercise adherence. Therefore, we developed a novel "Relaxing-Vibration Training (RVT)" consisting of 25 postures using vibration stimulation of skeletal muscle and determined the feasibility of RVT for glycemic management. Thirty-one participants with obesity were enrolled in a controlled trial (CT) and experimental trial (ET) based on a 75 g oral glucose tolerance test (OGTT). During the CT, participants were required to rest in a quiet room. During the ET, the RVT program (50 Hz, 4 mm), consisting of 25 postures of relaxation and stretching on the vibratory platform, was performed for 40 min. Subsequently, the participants rested as in the CT. Subjective fatigue and muscle stiffness measurements and blood collection were conducted before and after RVT. In both the CT and ET, interstitial fluid (ISF) glucose concentrations were measured every 15 min for 2 h. The incremental area under the curve value of real-time ISF glucose during an OGTT was significantly lower in the ET than in the CT (ET: 7476.5 ± 2974.9, CT: 8078.5 ± 3077.7, effect size r = 0.4). Additionally, the levels of metabolic glucose regulators associated with myokines, muscle stiffness, and subjective fatigue significantly improved after RVT. This novel RVT suggests that it is effective in glycemic management with great potential to improve impaired glucose tolerance and T2D with obesity in the future.

Abstract
AIM Although the validity of the assessment in older adults has been supported by several studies, cross-sectional and longitudinal relationships between phase angle (PhA) and physical function by sex have not been clarified. This study aimed to examine (i) cross-sectional relationships and (ii) longitudinal relationships between PhA and physical function in older adults. METHODS A total of 816 and 445 community-dwelling older adults were included in cross-sectional and longitudinal analyses, respectively. We evaluated their physical function using grip strength, 5-repetition sit-to-stand test (5-STS), 5-meter habitual walk, Timed Up and Go test (TUG), single-leg balance with eyes open, and sit-and-reach test. A multifrequency bioelectrical impedance analyzer was used to determine the PhA at 50 kHz as well as the participants' body composition. RESULTS In the cross-sectional analysis, a higher PhA was significantly associated with higher grip strength, sit-and-reach, single-leg balance with eyes open, 5-STS and lower TUG in women, as well as higher grip strength, single-leg balance with eyes open, lower 5-STS and TUG in men, adjusting for age, body mass index and muscle mass. In the longitudinal analysis, there was a significant interaction between PhA and year in the TUG test (B = -0.08; 95% CI, -0.136 to -0.025; P = 0.005) in men. There was no significant interaction between the PhA value and year for the other physical functions. CONCLUSIONS The PhA is a useful indicator for assessing physical function in both older men and women. Furthermore, the PhA may be able to predict mobility limitation in older men.

Abstract
BACKGROUND The amyloid-β1-42 (Aβ42) level is a biomarker that is widely used to evaluate individual cognitive dysfunction early in neurodegenerative diseases, as well as differentiate between normal cognitive function, mild cognitive impairment, Alzheimer's disease, and vascular cognitive impairment. OBJECTIVE Our cross-sectional study evaluated the association between daily exercise and physical and cognitive function and Aβ42 levels among a subsample of 325 older adults from the Kasama Study. METHODS Participants (age: 74.5 [range 65-90] years) were classified into three exercise groups: the dual-task (DEG, n = 128), single-task (SEG, n = 122), and non-exercise (NEG, n = 75) groups. The main outcomes were the plasma Aβ42 levels and the scores of the five cognitive (5-COG) tests and five cognition-related physical function (5-PHYS) tests. RESULTS The Aβ42 levels and 5-COG and 5-PHYS scores were higher in the SEG and DEG than in the NEG. The Aβ42 levels were higher in the DEG than in the NEG (p = 0.008). CONCLUSIONS Physical activities such as regular exercise may benefit older adults, improving their cognitive and physical function.

Abstract
We prospectively investigated the association between acceptable travel distances (i.e., walking and cycling) and the incidence of functional disability and mortality among older Japanese adults. A baseline survey was conducted in 2013 among 7618 individuals aged ≥65 years in Kasama City, Japan, and they were tracked through the city's database until 2021. Acceptable travel distances were assessed using a questionnaire. Outcomes (i.e., functional disability and mortality) were gathered as binary (incident or not) with survival time. A multivariable-adjusted Cox proportional-hazards model indicated that shorter acceptable walking and cycling distances were markedly linked with higher risks of functional disability and mortality. In conclusion, acceptable distances of ≤500 m for walking and ≤1 km for cycling were associated with higher risks of functional disability and mortality among older adults.

Abstract
Study objective Traditionally, age-related deterioration of sleep architecture in older individuals has been evaluated by visual scoring of polysomnographic (PSG) recordings with regard to total sleep time and latencies. In the present study, we additionally compared the non-REM sleep (NREM) stage and delta, theta, alpha, and sigma wave stability between young and older subjects to extract features that may explain age-related changes in sleep. Methods Polysomnographic recordings were performed in 11 healthy older (72.6 ± 2.4 years) and 9 healthy young (23.3 ± 1.1 years) females. In addition to total sleep time, the sleep stage, delta power amplitude, and delta, theta, alpha, and sigma wave stability were evaluated by sleep stage transition analysis and a novel computational method based on a coefficient of variation of the envelope (CVE) analysis, respectively. Results In older subjects, total sleep time and slow-wave sleep (SWS) time were shorter whereas wake after sleep onset was longer. The number of SWS episodes was similar between age groups, however, sleep stage transition analysis revealed that SWS was less stable in older individuals. NREM sleep stages in descending order of delta power were: SWS, N2, and N1, and delta power during NREM sleep in older subjects was lower than in young subjects. The CVE of the delta-band is an index of delta wave stability and showed significant differences between age groups. When separately analyzed for each NREM stage, different CVE clusters in NREM were clearly observed between young and older subjects. A lower delta CVE and amplitude were also observed in older subjects compared with young subjects in N2 and SWS. Additionally, lower CVE values in the theta, alpha and sigma bands were also characteristic of older participants. Conclusion The present study shows a decrease of SWS stability in older subjects together with a decrease in delta wave amplitude. Interestingly, the decrease in SWS stability coincided with an increase in short-term delta, theta, sigma, and alpha power stability revealed by lower CVE. Loss of electroencephalograms (EEG) variability might be a useful marker of brain age.

Abstract
Background Liposarcoma is one of the most common soft tissue sarcomas, but is extremely rarely found in the esophagus. There have been no reports of esophageal liposarcoma together with superficial carcinoma of the esophagus. Here, we report a patient who underwent complete resection of esophageal liposarcoma with carcinoma via a cervical approach. Case presentation A 66-year-old man was diagnosed with an esophageal tumor 11 years ago, but he left it untreated. He presented to our hospital with progressive dysphagia and appetite loss since the previous year. Esophagogastroduodenoscopy (EGD) showed a large pedunculated submucosal tumor (SMT) originating at the esophageal entrance, extending to the gastroesophageal junction. Additionally, there was a superficial carcinoma on the surface of the SMT, 30 cm from the incisor teeth. Three-dimensional computed tomography (3D-CT) showed a giant elongated intraluminal tumor extending downwards from the cervical esophagus. We diagnosed a giant esophageal polyp accompanied by a superficial carcinoma and performed tumor resection via a cervical approach. The excised specimen consisted of a 23.0 × 8.5 cm polypoid mass. The final diagnosis by histopathological and immunohistochemical examination was well-differentiated liposarcoma and esophageal squamous cell carcinoma. He was discharged on postoperative day 14 with drastic improvement in his swallowing ability. Conclusion We reported an extremely rare case of esophageal liposarcoma together with esophageal squamous cell carcinoma that was successfully resected through a small cervical incision.

Abstract
We evaluated the clinical outcome and assessed the safety of robot-assisted distal pancreatectomy(RADP)of early 5 cases in our institutional introduction. We followed the guidelines for introduction of robot-assisted pancreatectomy proposed by Japanese Society of Endoscopic Surgery. Patients' characteristics were 2 men and 3 women, 45-79(median 52) years old, and 3 patients with neuroendocrine neoplasm, 1 with intraductal papillary neoplasm and 1 with mucinous cystic neoplasm. Spleen-preserving RADP was performed in 2 cases. Clinical outcomes of 5 cases underwent RADP were, operation time was 308-437(median 330)minutes, blood loss was 5-270(median 100)mL and none received transfusion. Postoperative pancreatic fistula and postoperative complication more than Grade Ⅲa(Clavien-Dindo classification)were none. Postoperative hospital stay was 7-11(median 8)days. RADP in our institution was safely introduced by following the proposal of guidelines.

Abstract
OBJECTIVE This study aimed to ascertain the physical-fitness trends among community-dwelling older adults using performance testing. The results of the evaluation conducted during the COVID-19 pandemic were compared to data from the pre-pandemic period. METHODS A total of 240 community-dwelling older adults who participated in a health checkup program from 2016-2020 underwent the following tests: grip strength (upper limb muscle), single-leg balance with eyes open (static balance), sit-and-reach test (flexibility), timed up-and-go test (TUG, functional mobility), 5 meter habitual walk (walking ability), and hand working with pegboard (hand dexterity). Linear mixed effect models were applied to the hierarchical dataset: repeated data (Level 1), pre-pandemic (2016-2019), pandemic (2019-2020) (Level 2), and individuals (Level 3). Fixed effects and interactions were estimated for the survey year (Level 1), and between the survey year and pre- and post-pandemic (Level 2), with the range of decline set measured in terms of its standardized partial regression coefficient, "B," from 2019-2020. RESULTS The items for which significant cross-level interactions were identified. In males, the following items showed significant cross-level interactions: sit and reach test (B=-2.56, 95% CI: -4.45--0.66 cm), TUG (+0.39, 0.21-0.56 sec) and 5 meter habitual walk (+0.15, 0.04-0.27 sec). In females items except single-leg balance with eyes open showed significant cross-level interactions: grip strength (-0.58, -1.11--0.05 kg), sit-and-reach test (-3.53, -5.11--1.95 cm), TUG (+0.15, 0.03-0.27 sec), for 5 meter habitual walk (+0.14, 0.04-0.24 sec), and hand working with pegboard (+0.89, 0.28-1.51 sec). CONCLUSION In both males and females, a significant deterioration in flexibility and mobility movement ability was observed in 2019-2020. In addition, upper limb muscle strength and hand dexterity movement deteriorated in females.

Abstract
AbstractAlthough recent studies have examined the bidirectional associations between physical activity and sleep parameters, few have focused on older adults utilizing objective assessments, such as polysomnography. This micro-longitudinal observational study included 92 Japanese older adults (aged 65–86 years) who underwent objective evaluations of sleep quality using polysomnography and completed subjective sleep-related questionnaires. Activity levels were assessed using an accelerometer. Polysomnography, subjective sleep-related questionnaires, and accelerometer were administered for 7 consecutive days. Multilevel models (participant-, day-level) were used to examine the temporal associations of objective and subjective sleep parameters with sedentary behavior and physical activity. In the day-level analysis, higher levels of sedentary behavior during daytime were associated with longer rapid eye movement (REM) sleep, shorter REM latency, lower levels of non-REM sleep (stage N3), and reduced delta power during daytime. Higher levels of low-intensity physical activity during daytime were associated with lower levels of REM sleep, longer REM latency, and increased stage N3 sleep in the day-level analysis. Higher levels of moderate-to-vigorous physical activity were associated with increased REM latency. Longer subjective sleep time was associated with increased next-day moderate-to-vigorous physical activity. Thus, low-intensity physical activity may provide objective benefits related to deep sleep parameters in older adults.

Abstract
Background: Moderate- to vigorous-intensity physical activity (PA) may reduce the risk of dementia; however, few studies have examined the effects of PA intensity on dementia risk. Objective: To prospectively examine the dose-response relationship of PA intensity with the incidence of suspected dementia in community-dwelling older adults. Methods: We conducted a baseline mail survey with an 8-year follow-up of 3,722 older adults in Japan. We assessed PA levels using the International Physical Activity Questionnaire short form and calculated the amount of time per week spent performing moderate- and vigorous-intensity PA (VPA). Information regarding suspected dementia was obtained from the city database during the follow-up period. Cox proportional-hazard models with age as time scale, and delayed entry and restricted cubic spline regression as variables were used to estimate risk of developing suspected dementia, excluding cases occurring < 1 year after baseline evaluation. Results: The cumulative incidence of suspected dementia during the follow-up period was 12.7% . Compared with those who did not practice moderate-intensity PA (MPA), those who practiced≥300 min (hazard ratio, 0.73; 95% confidence interval 0.56–0.95) of MPA showed a lower risk of developing suspected dementia. Furthermore, when the dose-response relationship was examined, the hazard of developing suspected dementia decreased almost linearly with MPA. A significantly lower hazard was observed from 815 minutes/week. There was no significant association between VPA and suspected dementia. Conclusion: This study suggested that MPA is often practiced in older adults and this PA intensity has a sufficiently favorable effect on dementia prevention.

Abstract
Objectives: Frailty might be useful to identify older drivers who are at risk for traffic crashes. We aim to examine the association between pre-frailty/frailty defined by the Kihon Checklist (KCL) and the involvement of traffic crashes and clarify whether some domains of the KCL are associated with traffic crashes.Methods: This cross-sectional study analyzed data from 2,208 Japanese community-dwelling older drivers aged ≥ 65 years in Kasama City, who participated in our postal survey in November 2019. A self-reported history of traffic crashes was used to divide participants into non-crash-involved and crash-involved groups.Results: A total of 192 (8.7%) participants had been involved in traffic crashes in the past year. The crash-involved group was found to have gained more body mass index, driven more frequently, and scored higher on the total KCL score than the non-crash-involved group (all P < .05). Binary logistic regression analyses showed that after adjusting for age, sex, education, driving frequency, and driving distance, pre-frailty (OR = 1.52, 95% CI: 1.10-2.10) was more significantly associated with traffic crashes as compared to robustness. Those who had impairment in the oral domain (OR = 1.57, 95% CI: 1.09-2.27) and memory domain (OR = 1.38, 95% CI: 1.01-1.90) were also more likely to be involved in traffic crashes.Conclusion: The results suggest that identifying pre-frailty may play an important pole in crash prevention. Additionally, more attention should be given to older drivers with oral dysfunction and cognitive impairment.

Abstract
AIM To determine the relationship between performance on the Digital Trail Making Peg test (DTMP) and cognitive function in older adults. METHODS A total of 203 community-dwelling older adults (mean age: 76.4±5.1 years old) participated in this study. The five-cog test was used to assess the cognitive function. The DTMP measured completion time, number of errors and intra-individual variability for performance variability (coefficient of variation, CV; inter-elemental variability, IEV). Spearman's rank correlation coefficient (ρ) was calculated to examine the association between each variable. In addition, a multiple regression analysis was performed with the cognitive function score as the dependent variable and the DTMP completion time, number of errors, CV, and IEV as the independent variables, with adjusting for the sex, age, years of education, body mass index, medical history, depression, and physical function. RESULTS The rank correlation coefficients with cognitive function scores were as follows: completion time, ρ = -0.479 (P < 0.01), number of errors, ρ = -0.068 (P = 0.332), CV, ρ = 0.085 (P = 0.225), IEV, ρ = -0.316 (P < 0.01). The results of the multiple regression analysis showed that completion time (β = -0.566), CV (β = 0.164), IEV (β = 2.736) were significantly associated with cognitive function scores. CONCLUSIONS The shorter the DTMP completion time, the better the overall cognitive function. However, the intra-individual variability of CV and IEV did not show consistent results, with smaller values indicating less intra-individual variability.

Abstract
Introduction Dual‐task (DT) exercise can act as a substitute, which can help improve both physical and cognitive functions. Thus, this study investigated the effects of a game‐like cognitive DT exercise called “Synapsology” (SYNAP) among the oldest residents of a nursing home. Methods Participants (aged 85–97 years) were assigned to the intervention group (n = 12) and the control group (n = 12). The intervention group underwent 60‐minute sessions, twice a week for 24 weeks. Results A comparison of the Mini‐Mental State Examination scores and six physical function tests, before and after the intervention, shows that the SYNAP had a positive impact on the cognitive and physical functions among the intervention group. Discussion These findings suggest that SYNAP may help maintain or improve cognitive and physical functions among older adults compared to no interventions. Therefore, SYNAP would act as a beneficial tool amidst a “superaging” society like Japan.

Abstract
The combined intake of citrulline (CIT) and leucine (LEU) can stimulate protein synthesis. Therefore, this study aimed to investigate the effect of combined intake of CIT and LEU accompanied by exercise for 20 weeks on body composition, physical activity (PA), and amino acid concentrations in older Japanese women with low body mass index (BMI) (16 to 21 kg/m2) using a randomized, double-blind, placebo-controlled design. The supplement was administered twice a day for 20 weeks (Ex (exercise) + CIT·LEU group, n = 10: mainly 0.8 g CIT and 1.6 g LEU; Ex + Placebo group, n = 13: mainly 3.5 g carbohydrate). Additionally, both groups exercised (weight-bearing exercise, square stepping exercise) once a week for 75 min. Body composition, PA, and amino acid concentrations in the plasma were measured. Body weight, BMI, body mass, household PA, total PA, and phenylalanine significantly increased in the Ex + CIT·LEU group (p < 0.05) post intervention. This study suggests that the combined intake of CIT and LEU accompanied by exercise can improve body weight, BMI, body mass, and PA in older women with low BMI, which may prevent sarcopenia and frailty.

Abstract
Background This study investigated whether daily physical activity of older adults, combined with social relationships, is associated with the risk of sleep disorder. Further, it determined whether a high level of one variable with a low level of the other, leads to a significantly lower risk of sleep disorder than low levels of both. Methods The sample comprised 1339 community-dwelling older Japanese adults: 988 in Study 1 and 351 in Study 2. The level of daily physical activity and range of social relationships were assessed using the Physical Activity Scale for the Elderly and the Lubben Social Network Scale, respectively. The Pittsburgh Sleep Quality Index was used to assess sleep disorder. To test the combined relationships and effects in Studies 1 and 2, the medians for the respective scores of each of the following four groups that the participants were categorized into, were calculated: (1) low activity group with low social relationships, (2) low activity group with high social relationships, (3) high activity group with low social relationships, and (4) high activity group with high social relationships. After adjusting for potential confounders, a logistic regression analysis was conducted in Study 1. After adjusting for potential confounders, a Cox proportional hazards regression analysis was conducted in Study 2. Results Study 1 revealed that the high activity group with high social relationships showed a significantly lower risk of sleep disorder (ORs: 0.585, 95% CI: 0.404–0.847) than the low activity group with low social relationships. Study 2 also revealed that the high activity group with high social relationships showed a significantly lower prevalence of sleep disorder (HRs: 0.564, 95% CI: 0.327–0.974) than the low activity group with low social relationships. Conclusions Our findings suggest that for older adults with high social relationships, being physically active is favorably associated with sleep quality. However, a high level of one variable with a low level of the other has not been confirmed in improving sleep quality among older adults.

Abstract
Abstract
Background and purpose
Arrhythmias such as atrial fibrillation (AF) is often associated with depression, with vague anxiety about symptom and the risk of serious complication such as stroke or heart failure. In the geriatric population, geriatric depression often occurs with an increase of physical illness and has substantial costly and quality of life implications for functionality and life satisfaction. However, few studies have investigated relationship between geriatric depression and Quality of Life (QoL), and arrhythmia symptoms (palpitation, dyspnea and chest discomfort).
Method
Between November 2019 and October 2020, elderly people (≥65 years) who participated in the AF awareness symposium were enrolled in this study. They were divided into 4 groups according to the presence or absence of chest symptom and AF, and were examined geriatric depression by Geriatric depression scale (GDS)-15 and Quality of Life (QoL) by the 12-item Short- Form Health Survey (SF-12) including physical and mental health status.
Results
Of the 1511 subjects, 1364 were analyzed after excluding 147 with missing values. Among them, 911 were in the non-AF group without symptom (Group A), 43 in the AF group without symptom (group B), 323 in the non-AF group with symptom (group C), and 87 in the AF group with symptom (group D).
Geriatric depression rates (defined as GDS-15 ≥10) were 2.7% in non-symptomatic group (2.7% in A [n=25] and 2.3% in B [n=1]) and 7.8% in symptomatic group (7.4% in C [n=24] and 9.2% in D [n=8]). (P<0.05) In multivariate regression analysis, an increased risk of geriatric depression was observed in groups C and D (group C: odds ratio [OR]=2.54, CI: 1.40, 4.61, P<0.01 and group D: OR=3.13 CI: 1.16, 7.57, P=0.02).
The mean values of physical and mental health status in SF-12 were 48.5 (±7.9) and 56.7 (±6.8) in A, 44.6 (±10.7) and 57.3 (±7.3) in B, 45.0 (±9.9) and 53.8 (±7.7) in C, and 43.4 (±10.8) and 54.8 (±8.6) in D, respectively. Physical health status in SF-12 was associated with group C (C vs A: estimate −2.95 [CI: −4.03, −1.87], p<0.01) and D (D vs A: estimate −2.93 [CI: −4.88, −0.97], p<0.01), other than heart failure, older age and female. Mental health status in SF-12 was associated with group C (C vs A: estimated −2.34 [CI: −3.72, −1.42], p<0.01), heart failure, hypertension, older age, female and group D (D vs A: estimate −1.63 [CI: −3.31, 0.05], p=0.06), but not statistically significant. Individuals with arrhythmia symptom (group C and D) had lower physical and mental health status than those without (group A and B) (P<0.05).
Conclusion
Older adults with arrhythmia symptoms were more likely to have geriatric depression and low QoL, especially those with symptomatic AF, with a geriatric depressive complication rate of 9.2%. Further studies are needed to investigate whether improving physical health status can improve QoL and geriatric depression.

Atrial fibrillation (AF) is associated with increased risks of stroke and heart failure. AF risk prediction can facilitate the efficient deployment of diagnosis or interventions to prevent AF.
Purpose
We sought to assess the combination prediction value of Holter electrocardiogram (Holter ECG) and the CHARGE-AF score (Cohorts for Aging and Research in Genomic Epidemiology-AF) for the new-onset of AF in a single center study. We also investigated the association between clinical findings and the new-onset of cerebral cardiovascular events.
Methods
From January 2008 and May 2014, 1246 patients with aged≥20 undergoing Holter ECG for palpitations, dizziness, or syncope were recruited. Among them, 350 patients were enrolled in this study after exclusion of 1) AF history at the time of inspection or before, 2) post cardiac device implantation, 3) follow-up duration <1 year, and 4) no 12-lead ECG records within 6 months around Holter ECG.
Results
During the 5.9-year follow-up, 40 patients (11.4%) developed AF incidence. Multivariate cox regression analysis revealed that CHARGE-AF score (hazard ratio [HR]: 1.59, 95% confidence interval (95% CI): 1.13–2.26, P<0.01), BMI (HR: 0.91, 95% CI: 0.83–0.99, P=0.03), frequent supraventricular extrasystoles (SVEs) ≥1000 beats/day (HR: 4.87, 95% CI: 2.59–9.13, P<0.001) and first-degree AV block (HR: 3.52, 95% CI: 1.63–7.61, P<0.01) were significant independent predictors for newly AF. The area under the ROC curve (AUC) of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was greater than the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.82 vs 0.66, 95% CI: 0.56–0.75, respectively). On the ROC curve, the CHARGE-AF score of 12.9 was optimum cut-off value for newly AF. Patients with both the CHARGE-AF score≥12.9 and SVEs≥1000 developed AF at 129.0/1000 person-years, compared with those with the CHARGE-AF score<12.9 and SVEs≥1000 (48.9), the CHARGE-AF score≥12.9 and SVEs<1000 (40.0) and the CHARGE-AF score<12.9 and SVEs<1000 (7.4), respectively. In multivariate cox regression analysis, age, past history of congestive heart failure and myocardial infarction, and antihypertensive medication were significant predictors of cerebral cardiovascular events (n=43), all of which signifying the components of the CHARGE-AF score. The AUC of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was not different from the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.81 vs 0.73, 95% CI: 0.64–0.82, respectively).
Conclusion
CHARGE-AF score has higher predictive power of both the new incident AF and cerebral cardiovascular events. The combination of CHARGE-AF score and SVEs≥1000 beats/day in Holter ECG can demonstrate the additional effect of prediction ability for the new incident AF, but not for cerebral cardiovascular events.

Abstract
The aim of this study was to clarify the effect of living alone on the cognitive function of older people and the mediating effect of instrumental activities of daily living (IADL) ability.The data for a final sample of 3276 participants aged 65 years and above who did not require long-term care at the baseline were used from a 4-year prospective cohort study conducted in Kasama City, Japan. Demographic data including age, sex, and depression at baseline were used as covariates. The Kihon checklist evaluated the IADL ability at baseline and cognitive function at follow-up. The characteristics of those living alone and with others were compared using the student t test and χ2 test. The effect of living alone on cognitive function was analyzed using logistic regression analysis. Mediation analyses determined the mediating effects of IADL.A total of 325 participants were living alone; they were significantly older than those living with others, more likely to be female, not provide emotional support, and have low physical function, more severe depression, and lower IADL disability. Living alone had a significantly lower risk of cognitive decline at follow-up than living with others. The mediation analysis revealed that IADL disability at follow-up was significantly associated with cognitive decline. Thus, greater IADL ability decreased cognitive decline risk.Older people living alone had a significantly lower risk of cognitive decline, and cognitive function significantly mediated IADL ability. Health support for enhancing IADL abilities may help older people living alone maintain good cognitive function.

Abstract
Background The Square Stepping Exercise (SSE) is an exercise training program incorporating cognitive and physical exercise components, which was originally developed for older adults to reduce falling risks. SSE’s potential in delaying cognitive decline in older adults seems to be promising. However, there is scarce research on the SSE program with young adults. Furthermore, the outbreak of coronavirus disease has imposed people to change their lifestyle and behaviors, including exercise behaviors. Hence, the purpose of this study was to examine the acute effects of a home-based online SSE trial on cognitive and social functions in sedentary young adults. Methods A total of 18 young adults (6 males, 12 females) participated in the present study. They completed two exercise conditions (SSE and active control exercise), consisting of 3 sessions per week, over 2 weeks. A 2 times (pre vs. post) × 2 conditions (SSE vs. active control) repeated-measures ANCOVA was conducted on the score of the Modified Card Sorting Task with age and education year as covariates. A one-way repeated-measures MANOVA was performed on the subscale scores of the Physical Activity Group Environment Questionnaire to examine the effects of the exercise conditions (SSE vs. active control) on group cohesion. Results SSE was found effective to improve executive function such as abstract reasoning, mental flexibility, and problem-solving skills. Furthermore, participants’ perceptions of social interaction with their group, and closeness and bonding existing in their group were significantly higher in the SSE condition than the active control condition. Conclusions In the present study, SSE was conducted online and found to be effective to enhance executive function and group cohesion in sedentary young adults. These novel approach and findings are the strengths of the present study. People aged 60 years and over are more vulnerable to the coronavirus and at higher risk of developing serious illness. Given the coronavirus pandemic circumstances, it is worthwhile to explore the possibility of the online SSE approach to older adults in future research.

Abstract
We clarified the relationship between occupational dysfunction and social isolation among community-dwelling adults. We used a self-administered questionnaire with a cross-sectional study for 2879 independently living older adults in Kasama City, Japan. Participants responded to a self-reported questionnaire in November 2019. Occupational dysfunction and social isolation were assessed. The participants were classified into two groups: healthy occupational function group, and occupational dysfunction group. To examine the relationship between occupational dysfunction and social isolation, we performed a logistic regression analysis with social isolation as a dependent variable and occupational dysfunction as an independent variable. In the crude model, the occupational dysfunction group had a higher risk of social isolation than the healthy occupational function group (odds ratio (OR) = 2.04; 95% confidence interval (CI), 1.63–2.55; p < 0.001). In the adjusted model, the occupational dysfunction group had a higher risk of social isolation than the healthy occupational function group (OR = 1.51; 95% CI, 1.17–1.94; p = 0.001). The results showed that occupational dysfunction was significantly associated with social isolation. These results can be used in constructing a support method for social isolation from a new perspective.

Abstract
OBJECTIVE This study aimed to determine whether the timing of exercise influenced the effects of home-based low-intensity stepping exercises on the sleep parameters of older adults. METHOD For 8 weeks, 60 healthy older adults participated in a randomized controlled trial, performing low-intensity aerobic exercise (70-80 bpm) for about 30 minutes every day at home, either in the morning (from waking until 12:00) or evening (18:00 to bedtime). RESULTS In the evening exercise group, both subjectively and objectively measured sleep latency significantly improved throughout the intervention. Further, postintervention subjective sleep satisfaction was significantly higher in the evening group (6.2 ± 1.3 points) than in the morning group (5.2 ± 1.4 points; P = .006). Additionally, sleep variables related to evening exercise had larger effect sizes (Cohen d) than those performed in the morning. CONCLUSION Engaging in low-intensity stepping exercises during the evening is potentially a useful nonpharmacological approach to improving sleep quality among older adults.

Abstract
[Purpose] To examine the associations of exercise habits, particularly exercising in a group, with physical and cognitive functions in community-dwelling older adults. [Participants and Methods] A total of 615 older adults participated in this cross-sectional study. We conducted three physical performance tests (grip strength, five times sit-to-stand, and 5-meter walk tests) and the Five-Cog test (attention, memory, visuospatial, language, and reasoning). We investigated exercise habits using questionnaires and classified the participants into three groups as follows: those who did not exercise (n=86), those who exercised alone (n=168), and those who exercised in a group (n=362). To clarify the associations of exercise habits with physical and cognitive functions, we used the analysis of covariance with adjustment for potential confounders. [Results] The participants who exercised in a group had better lower limb strength than those who exercised alone and better scores for all the variables than the non-exercisers. Furthermore, those who exercised in a group scored significantly higher on the attention, memory, visuospatial, and overall cognitive function tests than those who exercised alone. [Conclusion] Our results highlight the importance of the social aspects associated with exercising, such as the presence of exercise peers, to improve the physical and cognitive health of older adults.

Abstract
BACKGROUND The effects of intensity, type, and time of day of physical activity on sleep are not well understood. An appropriate increase in core body temperature, due to physical activity during daytime, aids sleep in older adults. Our previous study showed that evening exercise has more positive effects on sleep quality in older adults when compared with morning exercise. However, older adults who do not exercise form a large part of the population. This study aimed to examine the distinct effects of low-intensity exercise and housework during the evening on sleep quality in older women. METHODS This randomized crossover study included 10 healthy older women aged 65-79 years. The participants engaged in low-intensity physical activity for 30 min, either aerobic exercise (70 steps per minute), housework (at the same intensity), or remained sedentary (control) 3 h before bedtime. Sleep was recorded polysomnographically, and self-reported sleep quality was assessed the next morning using the Oguri-Shirakawa-Azumi sleep inventory, Middle-Aged and Aged version (OSA-MA) questionnaire. RESULTS Compared with the control trial, core body temperature was significantly elevated in participants after each activity trial (0.5 ± 0.4 and 0.4 ± 0.4 °C for housework and aerobic exercise, respectively). There was a significant difference in sleep latency (14.2 ± 19.1, 9.9 ± 15.6, and 4.2 ± 3.5 min for control, housework, and aerobic exercise, respectively; ANOVA P = 0.011) among the trials. The delta power density after aerobic exercise was significantly higher than that after the control trial. We observed an increase of 53% and 15% in delta power during the 1st hour of sleep as a result of aerobic exercise and housework, respectively. The total score on OSA-MA was significantly higher after aerobic exercise (91.0 ± 5.4, 88.1 ± 6.9, and 108.6 ± 5.9 points for control, housework, and exercise, respectively). CONCLUSIONS Engaging in low-intensity aerobic exercise in the evening improved polysomnographic and self-reported sleep quality. Although housework increased core body temperature to the same level as that observed after aerobic exercise, self-reported sleep quality after housework was lower than that after aerobic exercise.

Abstract
Abstract
Background
Transcatheter aortic valve replacement (TAVR) has emerged as an important therapeutic option among intermediate- and high-risk patients with symptomatic severe aortic stenosis. Heart rhythm disorders frequently complicate TAVR, particularly atrial fibrillation (AF), which can affect >40% patients undergoing the procedure. There is wide variation in rates of new-onset AF (NOAF) following TAVR across the initial pivotal randomized trials and observational studies, but burden of AF in each patient is not well known. The aim of this study is to evaluate AF burden detected by continuous patch ECG monitor (WR-100; Fukuda-Denshi, Tokyo,Japan) in patients after TAVR.
Method
Among KPUM-TAVR cohort, 58 consecutive patients (mean age:85.5±5.5, 44 females) kept recording continuous patch ECG monitor for 14 days after the procedure of TAVR. We excluded 11 patients with ECG indicating AF before procedure (paroxysmal AF 5, persistent AF 6). Finally, 47 eligible patients were selected according to the study criteria. AF was defined as a presence of AF more than 30sec on ECG monitor. The incidence and burden of NOAF was assessed.
Results
We identified 9 of 47 patients (19.1%) who developed NOAF (94% of transfemoral access patients, 6% of non- transfemoral access patients). Patients developing NOAF and had higher Society of Thoracic Surgeons risk scores (5.9±3.8 vs 9.9±6.3 p=0.0187). AF was first observed from day1 to day13. Despite having a median CHA2DS2-VASc score of 5 (25th and 75th percentile: 5 to 6), only 33% of patients with NOAF were given oral anticoagulation during the follow-up.
Conclusion
By using continuous patch ECG monitor, NOAF can be identified in 19.1% of patients after TAVR, with wide variety of first onset of AF. Given the clinical significance of post-TAVR AF, additional studies are necessary to describe the optimal management strategy in this high-risk population.

Abstract
A 75-year-old woman had the habit of drinking vinegar. She had emergent transport to our hospital because of vomiting and unconsciousness. The patient underwent emergency surgery for esophageal rupture and septic shock. Intraoperatively, a 25 mm perforated area was found, and the visible esophageal mucosa was black. Because the suture closure or anastomosis was difficult and the shock was prolonged, she was placed in the intensive care unit after undergoing resection of the thoracic esophagus and thoracic drainage. Fifteen hours after the first surgery, we performed external esophagostomy and enterostomy. The third surgery was a retrothoracic cervical esophagogastric anastomosis, and reconstructive surgery was performed 60 days after the first surgery. Prolonged exposure to vinegar may have resulted in esophageal mucosal necrosis. This is a valuable case in which the esophageal mucosa was necrotic, and we performed esophagectomy and reconstruction as a damage control strategy to save her life.

Abstract
Not only does Japan has the world's longest healthy life expectancy, but also the world's longest average life span. This study investigated the effect of a novel dual-task (DT) exercise called "Synapsology" (SYNAP), developed as a game-like activity to improve older adults' physical and cognitive functions. Participants (n=24) with a mean age of 70.6 years (65-77 years) were randomly assigned to the SYNAP exercise group (SG, n=15) and the control group (CG, n=9). The SG participated in the DT intervention consisting of 60-minute sessions, twice a week, for 8 weeks. Physical function in timed-up-and-go had significant pre- and post- trial differences (P=0.017) in SG. In addition, cognitive function results in the a 25-hole trail-making peg test (P=0.004) and an oxidative stress marker (P=0.039) had a statistically significant difference within the SG. However, there were no significant differences in the physical and cognitive functions between SG and CG. In the study, older adults who participated in cognitive-motor DT intervention improved significantly with regard to motor ability and cognitive function results. Thus, a game-like DT exercise may help maintain the healthy life of older adults compared to no intervention.

Abstract
The aim of this cross-sectional study was to investigate the influence of replacing sedentary time with time engaged in one of two levels of physical activity on sleep quality using an isotemporal substitution model. The participants were 70 community-dwelling older Japanese adults (approximately 70% female). Physical activity types were measured using a triaxial accelerometer and categorized based on intensity as sedentary, light-intensity, and vigorous-intensity. The Pittsburgh Sleep Quality Index assessed subjective sleep quality. Objective sleep parameters were assessed using an actigraph. A series of multi-linear regression models analyzed the statistical relationships. Our findings showed that replacing 30 min of sedentary activity per day with an equal period of light-intensity physical activity significantly influenced sleep quality parameters. However, there was no significant difference in sleep quality when light-intensity activity was replaced with vigorous-intensity activity. Engaging in one activity type means less available time for other types of activity; habitual replacement of sedentary activity with light-intensity physical activity might have long-term benefits on the sleep quality of older people.

Abstract
The impact of body mass index (BMI) on postoperative survival in Japanese patients with pancreatic cancer is unclear. We examined the relationship between preoperative BMI and the prognosis of Japanese patients who underwent surgery for pancreatic cancer to determine whether BMI affects these patients' prognosis. Of the patients who underwent pancreatectomy between January 2004 and August 2015 at our institution, 246 were pathologically diagnosed with pancreatic tubular adenocarcinoma; the cancer was located in the pancreatic head (n=161) and in the body and tail (n=85). We classified the patients by BMI: underweight (n=22), normal weight (n=190), and overweight/obese (n=34) groups. We retrospectively analyzed medical records for patient characteristics, lesion location, disease stage, postoperative complications, chemotherapy, and prognosis. Lesion location, disease stage, postoperative complications, and chemotherapy were not significantly different among the BMI groups. The median survival times were as follows (days): all patients, 686; underweight, 485; normal weight, 694; and overweight/obese, 839. In a multivariate analysis, after adjusting for competing risk factors, low BMI was associated with an increased risk of death (normal weight: HR 0.58, p=0.038; overweight/obese: HR 0.54, p=0.059). High BMI was not found to be a postoperative factor for poor prognosis in Japanese pancreatic cancer patients.

Abstract
OBJECTIVE This study aimed to assess the relationship between weight gain from early adulthood and visceral fat accumulation. METHODS The participants were 549 men aged 42 to 64 years who were randomly selected from the local resident registry for the National Institute for Longevity Sciences' neighbourhood. They were asked to recall their weight at 18 years of age, and then, post-18 weight-change values were calculated for each participant (their current weight minus their weight at 18). The participants were divided according to their median body mass index (BMI) at 18 years of age (initial BMI) (<20.14 and ≥20.14 kg m-2). Visceral fat area (VFA) and subcutaneous fat area (SFA) were measured on computed tomography scans. RESULTS The participants with initial BMI of <20.14 kg m-2 exhibited greater post-18 weight changes than those with initial BMI of ≥20.14 kg m-2. The participants' post-18 weight-change values were negatively correlated with their initial BMI and positively correlated with both VFA and SFA. The slope of the regression line for the relationship between post-18 weight change and VFA was steeper in the participants with initial BMI of <20.14 kg m-2 (β = 4.36) than in those with initial BMI of ≥20.14 kg m-2 (β = 3.23). CONCLUSIONS Visceral fat accumulation is affected not only by an individual's post-18 weight gain but also by their initial BMI. Men who were thin in early adulthood experienced greater weight gain-associated VFA increases, but the same was not true for SFA.

Abstract
[Purpose] Exercise effects on executive functioning depend on exercise mode. We tested
the effects of three acute exercises in the sitting position—stepping, stretching, and
finger movement—on older adults’ executive functioning in comparison to a resting state
(i.e., control condition). [Subjects and Methods] Participants were 26 healthy older
adults (mean age, 71.8 ± 4.7 years). All participants performed the three sitting
exercises for 10 minutes; resting for an equal amount of time was used as a control
condition. These four conditions were presented in random order. The color-word matching
Stroop task was used to evaluate executive function before and after the sitting exercises
and control condition. [Results] All three sitting exercises significantly reduced Stroop
interference scores, while the control condition did not. There was a significant
difference between the finger movement exercise and the control condition in
pre-to-post-intervention changes in Stroop interference scores. [Conclusion] The acute
finger movement exercise was especially beneficial for executive function as evaluated by
the color-word matching Stroop task.

Abstract
[Purpose] There is a relationship between physical and cognitive functions; therefore,
impairment of physical function would mean cognitive decline. This study aimed to
investigate the association between change in physical and cognitive functions. [Subjects
and Methods] Participants were 169 healthy community-dwelling older adults who attend the
survey after three years from baseline (mean age, 72.4 ± 4.8 years). Grip strength,
one-leg standing balance, five-times-sit-to-stand test, timed up and go, 5-m habitual
walk, and a peg-moving task were used to evaluate physical performance. Five cognitive
function tests were used to assess attention, memory, visuospatial function, verbal
fluency, and reasoning. Cognitive function was defined as the cumulative score of these
tests. [Results] At baseline, five-times-sit-to-stand test, timed up and go, and hand
dexterity were independently associated with cognitive function. In longitudinal analyses,
changes in habitual walking speed and hand dexterity were significantly associated with
change in cognitive function. [Conclusion] Deterioration of specific physical function,
such as hand dexterity and walking ability, may be associated with progression of
cognitive decline. Decreasing extent of daily functions, such as hand dexterity and
walking ability, can be useful indices to grasp changes in cognitive function.

Abstract
[Purpose] The purpose of this study was to investigate which of the four chair-rising
methods has low-load and the highest success rate, and whether the GRF
parameters in that method are useful for measuring lower extremity function among
physically frail Japanese older adults. [Subjects and Methods] Fifty-two individuals
participated in this study. The participants voluntarily attempted four types of
Sit-to-stand test (one variation without and three variations with the use of their arms).
The following parameters were measured: peak reaction force (F/w), two force development
rate parameters (RFD1.25/w, RFD8.75/w) and two time-related parameters (T1, T2). Three
additional commonly employed clinical tests (One-leg balance with eyes open, Timed up and
go and 5-meter walk test) were also conducted. [Results] “Hands on a chair” chair-rising
method produced the highest success rate among the four methods. All parameters were
highly reliable between testing occasions. T2 showed strongly significant associations
with Timed up and go and 5-meter walk test in males. RFD8.75/w showed significant
associations with Timed up and go and 5-meter walk test in females. [Conclusion] Ground
reaction force parameters in the Sit-to-stand test are a reliable and useful method for
assessment of lower extremity function in physically frail Japanese older adults.
