Abstract
OBJECTIVE To investigate whether muscle quality is related to cognitive function in older adults living in the community. METHODS The participants were 40 community-dwelling older adults without a diagnosis of dementia (mean age, 78.85 ± 6.40 years; 31 women). The dependent variable was the score on the mild cognitive impairment (MCI) index of the Japanese version of the Neurobehavioral Cognitive Status Examination Five (range: 0-6; higher scores indicate MCI or possible dementia). RESULTS Multiple regression with Bayesian statistics was performed for analysis of muscle quality, as indicated by echo intensity (EI), with skeletal muscle mass index, gait speed, physical activity level, age, and sex as covariates. EI was significantly associated with the MCI index (expected a posterior = 0.04 [95% Bayesian confidence interval: 0.01, 0.07], t = 2.47, β = 0.41, p = 0.019). CONCLUSIONS The results suggest that EI may be related to the cognitive function of older adults living in the community. Future studies should examine whether focusing on EI can help prevent cognitive decline among older adults..

Abstract
This cross-sectional study aimed to determine the association between phase angle (PhA) and physical activity intensity in community-dwelling older Japanese adults. The intensity and time of physical activity for predicting high PhA were also examined. This study involved 67 community-dwelling older adults (mean age: 78.3 ± 5.5; female: 83.6%). We measured the physical activity and body composition of the participants. Physical activity was measured using a triaxial accelerometer, and light-intensity physical activity (LPA) and moderate-to-vigorous intensity physical activity (MVPA) hours per day were calculated from the results. Body composition was measured using Inbody S10, and the PhA was calculated from the measurements of the right side of the body. Bayesian statistical modeling revealed an association between PhA and MVPA (β = 0.256; p = 0.022; 95% Bayesian confidence interval [CI] = 0.001, 0.012), but not LPA (β = -0.113; p = 0.341; 95% Bayesian CI = -0.002, 0.001), even after adjustment for confounders. The cutoff value of MVPA predicting high PhA, calculated by the receiver operator characteristic curve, was 19.7 min/d (sensitivity = 0.906; specificity = 0.429). These results can be used to develop strategies to increase PhA in older adults and suggest that MVPA is important in this population.

Abstract
AIMS Regular self-weighing is effective in weight management and may help to mitigate the risk of underweight among older adults. We examined which factors of oral function are associated with a risk for underweight among community-dwelling older adults and whether regular self-weighing can mitigate that risk. METHODS This was a cohort study. Self-administered questionnaires were mailed to 7665 older adults in March 2019 (response rate 74.3%) and 7591 in March 2020 (response rate 74.7%). Among those who responded to both surveys, 3594 older adults who were not underweight in March 2019 were included (follow-up rate: 59.2%). We examined the association between dysphagia, poor masticatory function, and dry mouth and the development of underweight, and whether regular self-weighing reduced the risk for underweight. RESULTS The average age ± standard deviation of participants was 71.1 ± 3.4 years. There was a significant association between swallowing difficulty and the occurrence of underweight (odds ratio = 1.65, p = .012). However, this relationship did not differ significantly with regular self-weighing (p = .477). CONCLUSIONS These study findings suggest that to prevent underweight among community-dwelling older adults, it is important to focus on those with poor swallowing function.

Abstract
Objectives To evaluate whether tumor extracellular volume fraction (fECV) on contrast-enhanced computed tomography (CT) aids in the differentiation between intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC). Methods In this retrospective study, 113 patients with pathologically confirmed ICC (n = 39) or HCC (n = 74) who had undergone preoperative contrast-enhanced CT were enrolled. Enhancement values of the tumor (Etumor) and aorta (Eaorta) were obtained in the precontrast and equilibrium phase CT images. fECV was calculated using the following equation: fECV [%] = Etumor/Eaorta × (100 - hematocrit [%]). fECV values were compared between the ICC and HCC groups using Welch's t-test. The diagnostic performance of fECV for differentiating ICC and HCC was assessed using receiver-operating characteristic (ROC) analysis. fECV and the CT imaging features of tumors were evaluated by two radiologists. Multivariate logistic regression analysis was performed to identify factors predicting a diagnosis of ICC. Results Mean fECV was significantly higher in ICCs (43.8% ± 13.2%) than that in HCCs (31.6% ± 9.0%, p < 0.001). The area under the curve for differentiating ICC from HCC was 0.763 when the cutoff value of fECV was 41.5%. The multivariate analysis identified fECV (unit OR: 1.10; 95% CI: 1.01-1.21; p < 0.05), peripheral rim enhancement during the arterial phase (OR: 17.0; 95% CI: 1.29-225; p < 0.05), and absence of washout pattern (OR: 235; 95% CI: 14.03-3933; p < 0.001) as independent CT features for differentiating between the two tumor types. Conclusions A high value of fECV, peripheral rim enhancement during the arterial phase, and absence of washout pattern were independent factors in the differentiation of ICC from HCC.

Abstract
OBJECTIVE This study examined the association of living alone with changes in depressive symptom status and the moderating effect of non-face-to-face social interactions among older adults during the coronavirus disease (COVID-19) pandemic. DESIGN A longitudinal study. SETTING AND PARTICIPANTS This study recruited individuals aged ≥ 65 years without long-term care in one semi-urban city in Japan, who completed mailed questionnaires in March (baseline) and October 2020 (follow-up). METHODS Based on depressive symptoms assessed by the Two-Question Screening at baseline and follow-up, participants were classified as: "non-case," "onset," "remission," and "persistence." Non-face-to-face social interactions during the pandemic, including phone calls or emails with separated families or friends, were dichotomized as "less than weekly interactions" and "weekly interactions." A multinomial logistic regression analysis was conducted to examine the association of living arrangement (living alone or together) with changes in depressive symptoms status. RESULTS Data of 1001 participants were analyzed (mean age = 79.9 years). Of them, 13.8% lived alone. Overall, 40.6% participants were grouped as "non-case," 11.7% as "onset," 11.0% as "remission," and 27.1% as "persistence." Living alone was significantly associated with depressive symptom onset (odds ratio: 1.92; 95% CI: 1.03-3.56; P = .039), and a negative interaction (protective effect) was found between living alone and weekly non-face-to-face social interactions for depressive symptom onset. CONCLUSION AND IMPLICATIONS During the pandemic, older adults living alone had a higher depressive symptom risk, but non-face-to-face social interactions may have buffered this risk. Our findings suggest the importance of supporting older adults living alone in times of social restrictions such as the pandemic, and furthermore, maintaining social connections, including non-face-to-face relationships, is necessary to protect their mental health.

Abstract
Objectives It is likely that the number of older adults who eat alone has increased during the COVID-19 pandemic. Older adults who eat alone tend to experience weight fluctuations. Weight loss and underweight in older adults cause health problems. The study objective was to longitudinally investigate the association between changes in eating alone or with others and body weight status in older adults. Methods This longitudinal cohort study was conducted in March and October 2020 in Minokamo City, Gifu Prefecture, Japan. Questionnaire data for 1071 community-dwelling older adults were analyzed. Multinomial logistic regression analysis was performed using changes in eating alone or with others as the independent variable and body weight status as the dependent variable. The analysis was adjusted for age, sex, living arrangements, educational level, diseases receiving medical treatment, cognitive status, depression, and instrumental activities of daily living. Missing data were imputed using multiple imputation. Results The average age of participants was 81.1 y (SD, 4.9 y). Individuals who reported eating alone in both surveys were more likely to report weight loss than those who reported eating with others in both surveys (adjusted model: odds ratio, 2.25; 95% confidence interval, 1.06–4.78; P = 0.04). Conclusions These findings suggest that measures to prevent weight loss in older adults who eat alone are particularly important during the COVID-19 pandemic.

Abstract
BACKGROUND Social distancing measures to prevent the spread of coronavirus disease 2019 may cause changes in psychosocial factors. This study aimed to clarify changes in psychosocial factors among older adults before and after Japan's declaration of a state of emergency over coronavirus disease 2019. METHODS This was a longitudinal cohort questionnaire study. A baseline survey was conducted in March 2020, and a follow-up survey was conducted in August 2020. The subjects were 1103 community-dwelling older adults not certified as having long-term care needs who responded to both the baseline and follow-up surveys. Changes in psychosocial factors before and after the state of emergency declaration were analysed by gender using the McNemar-Bowker test. RESULTS Data for 397 men (mean age ± standard deviation: 80.6 ± 4.7 years) and 486 women (80.3 ± 4.3 years) were analysed in this study. The frequency of meeting friends increased over the study period for men (P = 0.04). An increasing number of women lived alone (P = 0.01). However, many people's financial status improved (P < 0.01), and the number of friends met in the previous month increased (P < 0.01). CONCLUSIONS None of the examined psychosocial factors worsened, except for the increase in the number of women living alone. However, many of the study subjects refrained from engaging in certain activities. If the coronavirus disease 2019 pandemic persists, changes in psychosocial factors may occur. Therefore, a long-term investigation of the secondary psychosocial effects of coronavirus disease 2019 is necessary.

Abstract
COVID-19 infections are particularly lethal in older adults; thus, social activities of older adults and their families in the community have been restricted. The threat of infection, restrictions on social activities, and limitations on the provision of care services for older adults could increase family caregivers’ burden and impact their mental health. This cross-sectional study examined the association between family caregiving and change in depression during the COVID-19 pandemic. In October 2020, we conducted a mailed questionnaire survey on a random sample of functionally independent community-dwelling older adults in a semi-urban area of Japan. Based on the depression status between March and October 2020, participants were classified into four groups: “consistently non-depressed,” “depression onset,” “recovering from depression,” and “remained depressed.” Participants were assessed for providing care for their family members or not. Caregiver participants were also assessed on their caregiving role (primary or secondary), the severity of their care-recipient’s needs, and an increased caregiver burden. Data from 957 older adults were analyzed. The participants’ mean age (SD) was 80.8 (4.8) years, and 53.5% were female. Multivariable multinomial logistic regression analysis revealed that family caregiving was associated with depression onset (OR=3.17 [95%CI=1.57-6.40], p=0.001) and remaining depressed (2.53 [1.36-4.71], p=0.004). Particularly, primary caregivers, those providing care for family members with severer care need-levels, and those with an increased caregiver burden had a higher risk of depression onset and remaining depressed. Family caregivers could have severe mental health conditions during the pandemic. Developing a support system is essential to protect their mental health.

Abstract
Objectives : We examined the association between social frailty and depressive symptoms among community-dwelling older adults during the coronavirus disease 2019 pandemic. Additionally, we investigated whether home exercise habits moderated the impact of social frailty on depressive symptoms. Methods : This cross-sectional study included 1,103 community-dwelling older adults (54.0% female, mean age [standard deviation] = 81.1 [5.0] years) from a semi-urban area of Japan who completed a mailed questionnaire survey in October 2020. Social frailty status was categorized as non-social frailty, pre-social frailty, and social frailty, which was assessed by financial difficulties, living alone, lack of social activity, and contact with neighbors. Depressive symptoms were defined as a Kessler 6 score ≥5. We performed a multivariable logistic regression analysis to examine the association between social frailty and depressive symptoms, and also conducted stratified analysis of home exercise habits during the pandemic. Results : A total of 309 (28.0%) participants had depressive symptoms. Compared with non-social frailty, social frailty was associated with depressive symptoms (odds ratio [OR] = 1.80, 95% confidence interval [95%CI] = 1.16–2.79, p = 0.009). A similar relationship was observed in those who did not exercise at home (OR = 2.10, 95%CI = 1.14–3.84, p =0.017). However, no such relationship was observed in those who did exercise at home (OR = 1.50, 95%CI = 0.79–2.85, p =0.213). Conclusions : Social frailty was associated with a risk of depressive symptoms during the pandemic. In addition, our findings suggested that home exercise may buffer the association between social frailty and depressive symptoms.

Abstract
Objectives Novel coronavirus disease (COVID-19) pandemic could increase the mental health burden of family caregivers of older adults, but related reports are limited. We examined the association between family caregiving and changes in the depressive symptom status during the pandemic. Methods This cross-sectional study included 957 (mean age [standard deviation] = 80.8 [4.8] years; 53.5% females) community-dwelling older adults aged ≥ 65 years from a semi-urban area of Japan, who completed a mailed questionnaire. Based on the depressive symptom status assessed with the Two-Question Screen between March and October 2020, participants were classified into four groups: “non-depressive symptoms,” “incidence of depressive symptoms,” “remission from depressive symptoms,” or “persistence of depressive symptoms.” Participants were assessed in October 2020 for the family caregiving status, caregiving role, the severity of care recipients’ needs, and increased caregiver burden during the pandemic, each with the simple question. Multinomial logistic regression analysis was applied to obtain the odds ratios (ORs) and 95% confidence intervals (CIs) for changes in depressive symptom status. Results Compared to non-caregivers, family caregivers were associated with the incidence (OR [95% CI] = 3.17 [1.55–6.51], p < 0.01) and persistence of depressive symptoms (OR [95% CI] = 2.39 [1.30–4.38], p < 0.01). Primary caregivers, caregivers for individuals with severe care needs, and caregivers with increased burden during the pandemic had a high risk of depressive symptoms. Conclusions Family caregivers had a high risk of depressive symptoms during the pandemic. Our findings highlight the need for a support system for family caregivers.

Abstract
OBJECTIVES We aimed to examine the association between the transition to social isolation and cognitive decline in older adults during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN Longitudinal study. SETTING AND PARTICIPANTS The study included participants from a community in a semiurban area of Japan. We conducted a mailed questionnaire survey of 2000 noninstitutionalized older adults who were randomly sampled. Of those who completed both the baseline and follow-up surveys in March and October 2020, respectively, participants aged ≥70 years without cognitive impairment at baseline were included in the analysis. METHODS Participants were classified into 4 groups based on their baseline and follow-up social isolation status, which were as follows: "remained nonisolated," "isolated from nonisolation," "nonisolated from isolation," and "consistent isolation." Self-reported cognitive function was assessed using the Cognitive Performance Scale, and level 2 (mild impairment) or higher (moderate to severe impairment) was defined as cognitive impairment. RESULTS Ultimately, 955 older adults were analyzed. The mean age of the participants was 79.6 years (standard deviation = 4.7) and 54.7% were women. During the follow-up period, 54 (5.7%) participants developed cognitive impairment. Multivariable logistic regression analysis revealed that compared with the group that remained nonisolated, the isolated from nonisolation and consistent isolation groups were significantly associated with the onset of cognitive impairment [isolated from nonisolation: odds ratio (OR) = 2.74, 95% confidence interval (CI) = 1.13-6.61, P = .026; consistent isolation: OR = 2.33, 95% CI = 1.07-5.05, P = .033]. CONCLUSIONS AND IMPLICATIONS Social isolation during the COVID-19 pandemic was associated with a decline in cognitive function among older adults. Attention to the social isolation process during the pandemic may be necessary to protect older adults' cognitive health.

Abstract
OBJECTIVES The coronavirus disease (COVID-19) pandemic has imposed restrictions on people's social behavior. However, there is limited evidence regarding the relationship between changes in social participation and depressive symptom onset among older adults during the pandemic. We examined the association between changes in social participation and the onset of depressive symptoms among community-dwelling older adults during the COVID-19 pandemic. DESIGN This was a longitudinal study. SETTING Communities in Minokamo City, a semi-urban area in Japan. PARTICIPANTS We recruited community-dwelling older adults aged ≥ 65 years using random sampling. Participants completed a questionnaire survey at baseline (March 2020) and follow-up (October 2020). MEASUREMENTS Depressive symptoms were assessed using the Two-Question Screen. Based on their social participation status in March and October 2020, participants were classified into four groups: "continued participation," "decreased participation," "increased participation," and "consistent non-participation." RESULTS A total of 597 older adults without depressive symptoms at baseline were analyzed (mean age = 79.8 years; 50.4% females). Depressive symptoms occurred in 20.1% of the participants during the observation period. Multivariable Poisson regression analysis showed that decreased social participation was significantly associated with the onset of the depressive symptoms, compared to continued participation, after adjusting for all covariates (incidence rate ratio = 1.59, 95% confidence interval = 1.01-2.50, p = 0.045). CONCLUSION Older adults with decreased social participation during the COVID-19 pandemic demonstrated a high risk of developing depressive symptoms. We recommend that resuming community activities and promoting the participation of older adults, with sufficient consideration for infection prevention, are needed to maintain mental health among older adults.

Abstract
Objectives: Increasing activity levels in older people is important for maintaining quality of life and ameliorating the risks of morbidity related to falls, depression, and dementia. This study aimed to clarify the seasonal variation effects on total energy expenditure, number of steps, time spent in low- and moderate- or high-intensity physical activities, and daily activities performed. Patients and Methods: This was a cross-sectional study of 22 community-dwelling older individuals (3 men, 19 women; mean age, 75.1 ± 7.3 years) living in three districts of Gero, Gifu, who participated in the Gero Salon Project hosted by the Social Welfare Councils. Evaluations were conducted in each season from September 2016 to August 2017. We used a uniaxial accelerometer, the Lifecorder device, which measures physical activity, and the Physical Activity Scale for the Elderly to evaluate activities of daily living. Data were analyzed using the multiple comparisons (Bonferroni correction) method. Results: Total energy expenditure and time spent in moderate- or high-intensity activities did not show seasonal variations. However, the lowest number of steps was taken during the winter, and the number of steps increased significantly from winter to spring. The time spent in low-intensity physical activities was significantly longer in the spring and summer than in the winter. There was no significant seasonal difference in total Physical Activity Scale for the Elderly score, leisure activities, domestic activities, or work-related activities. However, there was a significant difference between the summer and winter scores in "outdoor gardening," with the lowest score observed during the winter. Conclusions: With climate changes in the winter months, "outdoor gardening" becomes difficult, thus decreasing the number of steps taken. Therefore, it is necessary to identify other ways for older people to maintain physical activity during the winter season.

Abstract
PURPOSE To quantify dopaminergic neurodegeneration and iron overload in the substantia nigra pars compacta (SNpc) to evaluate Parkinson's disease (PD) using both quantitative susceptibility mapping (QSM) and neuromelanin imaging. MATERIALS AND METHODS We studied 39 PD patients (PD group) and 25 healthy controls (HC group) who underwent brain MRI with QSM and neuromelanin imaging. QSM and neuromelanin values of the SNpc were obtained using a voxel-based automated region segmentation system. The signal-to-noise ratio (SNR) of the SNpc in the neuromelanin images was calculated based on the mean value for the background region. The neuromelanin value was defined as the neuromelanin volume with an SNR higher than that of the background. The significance of the intergroup differences, and according to the severity stages in the PD group was tested for each QSM and neuromelanin value. Receiver-operating characteristic (ROC) analysis for diagnosing PD was performed for QSM and neuromelanin values. RESULTS The QSM value was significantly higher in the PD group than in the HC group (P < 0.05). The neuromelanin value was significantly smaller in the PD group than in the HC group (P < 0.05). The areas under the ROC curve were 0.68 and 0.86 for QSM and neuromelanin values, respectively. Using QSM and neuromelanin imaging to classify the PD stage was difficult. CONCLUSIONS Quantifying the SNpc alterations with our region-based approach is useful for the diagnosis of PD.

Abstract
BACKGROUND Upper-limb function is important in patients with hip fracture so they can perform activities of daily living and participate in leisure activities. Upper-limb function of these patients, however, has not been thoroughly investigated. OBJECTIVE The aim of this study was to evaluate the upper-limb motor and sensory functions in patients with hip fracture by comparing these functions with those of community-dwelling older adults (control group). METHODS We compared the results of motor and sensory function tests of upper-limb function - range of motion, strength, sensibility, finger dexterity, comprehensive hand function - between patients with hip fracture (n= 32) and the control group (n= 32). RESULTS Patients with hip fracture had significantly reduced grip strength, pinch strength, finger dexterity, and comprehensive hand function compared with the control group. CONCLUSIONS Most upper-limb functions are impaired in the patients with hip fracture. Thus, upper-limb function of patients with hip fracture should be considered during treatment.

Abstract
Exercise, such as cardiovascular fitness training, has been shown to have utility in improving executive function but is difficult for older adults with low mobility to perform. Accordingly, there is interest in the development of regimens other than high mobility exercises for older adults with low mobility. The aim of the present study was to evaluate the association between sensory motor function of the upper limb and executive function in community-dwelling older adults. A cross-sectional study was conducted in 57 right-handed, independent, community-dwelling older adults. Sensory motor function of upper limb, including range of motion, strength, sensation, finger dexterity, and comprehensive hand function was measured in both hands. Executive function was assessed using the Delta Trail Making Test. Multiple regression analysis indicated the finger dexterity of the non-dominant hand as independently associated with executive function (β = -0.414, P < 0.001). The findings of the present study may facilitate the development of exercise regimens for improving executive function that are more suitable for older adults with limited physical fitness levels. As this was a cross-sectional study, further studies are required to validate the efficacy of non-dominant finger dexterity training for improving executive function in older adults.

Abstract
[Purpose] (1) The aim of this study was to examine relations between clinical and
functional assessment and discharge destination and (2) to identify the optimal cutoff
point for estimating discharge to home after inpatient rehabilitation. [Subjects] The
subjects were 54 hip fracture patients (15 males, 39 females; mean age 81.3 ± 7.4 years)
living alone. [Methods] The patients were classified into two groups: those discharged to
home and those admitted to an institution. Age, gender, side of fracture, fracture type,
number of comorbidities, Functional Independence Measure motor score, and Functional
Independence Measure cognitive score were compared between groups. Multiple logistic
regression analysis was conducted with discharge to home as the dependent variable and
age, gender, side of fracture, fracture type, number of comorbidities, Functional
Independence Measure motor score, and Functional Independence Measure cognitive score as
independent variables. A receiver operating characteristic curve analysis was used to
identify a cutoff point for classification of the patients into the two groups. [Results]
Multiple logistic regression analysis showed that the Functional Independence Measure
cognitive score was a significant variable affecting the discharge destination. The
receiver operating characteristic curve analysis revealed that discharge to home was
predicted accurately by a Functional Independence Measure cognitive score of 23.5.
[Conclusion] Information from this study is expected to be useful for determining
discharge plans and for the setting of treatment goals.

Abstract
BACKGROUND AND PURPOSE Electrocardiogram-gated 4D-CTA is a promising technique allowing new insight into aneurysm pathophysiology and possibly improving risk prediction of cerebral aneurysms. Due to the extremely small pulsational excursions (<0.1 mm in diameter), exact segmentation of the aneurysms is of critical importance. In vitro examinations have shown improvement of the accuracy of vessel delineation by iterative reconstruction methods. We hypothesized that this improvement shows a measurable effect on aneurysm pulsations in vivo. MATERIALS AND METHODS Ten patients with cerebral aneurysms underwent 4D-CTA. Images were reconstructed with filtered back-projection and iterative reconstruction. The following parameters were compared between both groups: image noise, absolute aneurysm volumes, pulsatility, and sharpness of aneurysm edges. RESULTS In iterative reconstruction images, noise was significantly reduced (mean, 9.8 ± 4.0 Hounsfield units versus 8.0 ± 2.5 Hounsfield units; P = .04), but the sharpness of aneurysm edges just missed statistical significance (mean, 3.50 ± 0.49 mm versus 3.42 ± 0.49 mm; P = .06). Absolute volumes (mean, 456.1 ± 775.2 mm(3) versus 461.7 ± 789.9 mm(3); P = .31) and pulsatility (mean, 1.099 ± 0.088 mm(3) versus 1.095 ± 0.082 mm(3); P = .62) did not show a significant difference between iterative reconstruction and filtered back-projection images. CONCLUSIONS CT images reconstructed with iterative reconstruction methods show a tendency toward shorter vessel edges but do not affect absolute aneurysm volumes or pulsatility measurements in vivo.

Abstract
This paper describes a method for automated optimization of total hip arthroplasty (THA) planning incorporating joint functionalities. The optimal planning is formulated as maximum a posterior (MAP) estimation, which ensures the best-balance of joint functionalities and bone-implant spatial relations based on their statistical models derived from the training datasets prepared by an experienced surgeon. According to the performance evaluation, four of the six functionalities of the automatically optimized plans were almost equivalent to those of surgeon's plans, and two of them were improved. We consider these results showed a potential usefulness of the proposed method.

Abstract
AIM Falling is the leading cause of injury-related deaths in older adults, and a loss of balance is often the precursor to a fall. However, little is known about the rate at which balance declines with age. The objective of the present study was to determine whether there is an age-associated decline in static (SB) and/or dynamic (DB) balance in community-dwelling older women. METHOD SB and DB were determined in 971 older women. Intraclass correlation coefficients (ICC) were used to determine test-retest reliability. Sway velocity was used to measure SB standing on a platform and foam with eyes open and closed. DB was characterized by limits of stability (LOS) that measured end-point excursion (EXE) and maximum excursion (MXE) of the body's center of pressure. RESULTS ICC for EXE and MXE for the LOS test were excellent (EPE = 0.96, MXE = 0.96). ICC for SB tests, except for the eyes open firm surface condition (ICC = 0.10), showed a high level of reproducibility (ICC = 0.88 and 0.90). Relationships existed between age and SB (r = 0.31, P < 0.001), and between age and DB (r = -0.46--0.48, P < 0.001). The rate of decline for both DB and SB was approximately 1% per year. Age was significantly associated with all balance measures. DB got significantly lower with advancing age until 80 years, and then plateaued. SB did not decline with age until 80 years, and then decreased significantly thereafter. CONCLUSION Although large individual variation was found with balance ability, an age-related decline was found with both dynamic and static balance for Japanese older women.

Abstract
Persistence of foetal anastomoses between carotid and vertebrobasilar arteries is well recognised, but their bilateral presence is rare. We report a case of bilateral persistent hypoglossal arteries. Absence of bilateral vertebral arteries was incidentally noted on neck ultrasound examination. Subsequent MRI confirmed this and revealed persistent hypoglossal arteries that arose bilaterally from the cervical internal carotid artery, entered the cranium through the hypoglossal canal and joined the lower portion of the basilar artery.

Abstract
OBJECTIVE The aim of this study was to correlate the MRI appearance and pathological findings in each grade of the mucoepidermoid carcinoma (MEC) of the parotid gland. METHODS We reviewed surgically proven MECs of parotid glands in 20 patients. Pathologically, 5 tumours were high-grade, 3 were intermediate and 12 were low-grade. MR images were evaluated with emphasis on signal intensities on T(2) weighted images, margin characteristics and lymph node metastasis, correlating these with pathological features. RESULTS Among the high-grade MECs, four out of five tumours showed inhomogeneous low to intermediate signal intensity on T(2) weighted images, reflecting high cellularity. All tumours had an ill-defined margin, reflecting invasive tumour growth. Among the intermediate-grade MECs, all three tumours showed intermediate signal intensity on T(2) weighted images and two tumours had an ill-defined margin. Among the low-grade MECs, 11 of the 12 tumours had a hyperintense area on T(2) weighted images because of the existence of abundant mucin secreting cells. Seven tumours had an ill-defined margin, reflecting peritumoural inflammatory changes rather than invasive tumour growth. Lymph node metastasis was seen in three high-grade MECs. CONCLUSION MECs of the parotid gland show variable MRI findings reflecting their histological nature, which seems to have certain tendencies depending on the tumour grade.

Abstract
OBJECTIVE We investigated the image quality of multiplanar reconstruction (MPR) using adaptive statistical iterative reconstruction (ASIR). METHODS Inflated and fixed lungs were scanned with a garnet detector CT in high-resolution mode (HR mode) or non-high-resolution (HR) mode, and MPR images were then reconstructed. Observers compared 15 MPR images of ASIR (40%) and ASIR (80%) with those of ASIR (0%), and assessed image quality using a visual five-point scale (1, definitely inferior; 5, definitely superior), with particular emphasis on normal pulmonary structures, artefacts, noise and overall image quality. RESULTS The mean overall image quality scores in HR mode were 3.67 with ASIR (40%) and 4.97 with ASIR (80%). Those in non-HR mode were 3.27 with ASIR (40%) and 3.90 with ASIR (80%). The mean artefact scores in HR mode were 3.13 with ASIR (40%) and 3.63 with ASIR (80%), but those in non-HR mode were 2.87 with ASIR (40%) and 2.53 with ASIR (80%). The mean scores of the other parameters were greater than 3, whereas those in HR mode were higher than those in non-HR mode. There were significant differences between ASIR (40%) and ASIR (80%) in overall image quality (p<0.01). Contrast medium in the injection syringe was scanned to analyse image quality; ASIR did not suppress the severe artefacts of contrast medium. CONCLUSION In general, MPR image quality with ASIR (80%) was superior to that with ASIR (40%). However, there was an increased incidence of artefacts by ASIR when CT images were obtained in non-HR mode.

Abstract
Recently popularised, the combined angiography and CT (angio-CT) system is useful for correctly identifying the feeding arteries and their perfusion in various organs. We applied this system for advanced maxillary cancer to expose its feeding arteries and their supplying territories. In addition to the maxillary artery, extramaxillary feeding arteries were usually observed, including the ophthalmic, accessory meningeal, facial, transverse facial and ascending palatine arteries. These extramaxillary feeding arteries exhibited uniform tendencies, depending on the site of extramaxillary tumour extension.

Abstract
OBJECTIVES/HYPOTHESIS Lidocaine is a local anesthetic that is known to suppress tinnitus via systemic or local application; however, this effect has only limited duration. The current study aimed to establish a method for the sustained delivery of lidocaine into the cochlea using poly lactic/glycolic acid (PLGA) microparticles. STUDY DESIGN Experimental study. METHODS Lidocaine-loaded PLGA microparticles were produced and their in vitro-release profiles were examined. The lidocaine concentrations in the perilymph were measured at different time points following the application of the lidocaine-loaded PLGA microparticles to the round-window membranes of guinea pigs. The possible adverse effects of the local application of lidocaine-loaded PLGA microparticles were also examined. RESULTS The in vitro analyses revealed that the microparticles were capable of the sustained delivery of lidocaine. The in vivo experiments demonstrated the sustained delivery of lidocaine into the cochlear fluid, and the maintenance of high lidocaine concentrations in the perilymph for up to 3 days after application. Nystagmus and inflammation in the middle ear mucosa were not detected after the local application of lidocaine-loaded PLGA microparticles, although temporary hearing loss was observed. CONCLUSIONS Lidocaine-loaded PLGA microparticles were shown to be capable of the sustained delivery of lidocaine into the cochlea, suggesting that they could be used for the attenuation of peripheral tinnitus.

Abstract
Amrubicin is a new anticancer drug that has been shown to exert efficacy against small cell lung cancer. The pharmacokinetic parameters of amrubicin have not yet been investigated in hemodialysis patients, although it had been expected that amrubicin might not be cleared by hemodialysis because of its high lipid solubility, high protein binding rate and low urinary excretion rate. We encountered a case of small cell lung cancer on hemodialysis who was treated with amrubicin. We assayed the plasma concentrations of amrubicin and amrubicinol (its active metabolite) and analyzed the pharmacokinetic parameters of the drug in this hemodialysis patient. The results revealed that the pharmacokinetic parameters of the drug in this patient undergoing hemodialysis were similar to those in patients not on hemodialysis. Our results suggest that amrubicin and amrubicinol are cleared by hemodialysis, and that dose adjustment of amrubicin might not be required in hemodialysis patients.

Abstract
The purpose of this study was to investigate the reproducibility of volumetric software evaluation and manual evaluation of tumour growth. Three observers manually evaluated whether tumour volume was increasing, if it was unchanged, or if it had decreased in size in 2 serial CT examinations of 45 solid lung cancers. The tumour volumes were calculated 3 times using volumetric software and were evaluated using the same classifications as for manual evaluation. Both data sets were divided into three groups: growth or reduction with consistency among all three evaluations (group A), growth or reduction with consistency between only two evaluations (group B), and others (group C). The volume variation and relative volume variation were calculated from the median volumes measured by volumetric software. Although all 45 tumours were categorised in group A by volumetric software, only 21 tumours were categorised in group A by manual assessment. The relative volume variation of the manual assessment was 88.5 +/- 76.5%, 20.8 +/- 28.3% and 12.9 +/- 12.8% in group A, B and C, respectively. Significant differences were found between groups A and B (p<0.01) and between groups A and C (p<0.001). Inconsistency is often seen in manual assessment; in contrast, evaluation using volumetric software has good reproducibility, even when the relative change in tumour volume is small.

Abstract
BACKGROUND Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent attacks of fever with serosal inflammation. FMF gene (MEFV) mutations have been identified primarily in patients from Mediterranean populations. Although several clinical cases have been reported in Japan, there have been few reports to date on mutation analysis. We studied FMF patients and their relatives to examine the clinical and genetic features of this disease in the Japanese population. METHODS Twelve Japanese FMF patients who met the Tel Hashomer criteria and a total of 17 relatives from 5 of 10 families underwent molecular genetic studies to detect MEFV mutations. The characteristics of these Japanese FMF patients and geno-phenotypical correlations were examined. RESULTS Almost all of our patients had been suffering for a long time from fever of unknown origin and one patient also had systemic amyloidosis. In our 12 FMF patients, we detected the substitutions E84K, L110P, E148Q, R761H and M694I. We also newly diagnosed 2 relatives as having FMF based on clinical symptoms and the existence of FMF mutations. One patient was homozygous for E148Q, the patient with systemic amyloidosis was a homozygote for M694I and 4 patients from 3 families were compound heterozygotes for E148Q and M694I. Three patients in one family were compound heterozygotes for E148Q, L110P and M694I. There were 3 patients who were heterozygous for E84K, L110P-E148Q or M694I and had no other nucleotide changes in the exons of MEFV. On the other hand, 2 relatives who had never experienced symptoms of FMF were homozygous for L110P-E148Q as well as compound heterozygous for E148Q/E148Q-R761H. E148Q and M694I were the most frequently detected substitutions in our study. CONCLUSIONS MEFV mutations occur in Japanese FMF patients though FMF is rare in Japan. The identification of MEFV mutations could be a reliable diagnostic test for FMF. The results of genetic analyses on 14 Japanese FMF patients in this study revealed that E148Q and M694I are frequent alleles.

Abstract
1. In the present study, we evaluated fibrate-mediated potentiation of statin-induced apoptosis in IM-9 human lymphoblasts. 2. The pro-apoptotic effects of statin and fibrate were measured by flow cytometry with biotin-annexin V, followed by addition of avidin-fluorescein isothiocyanate and propidium iodide. Apoptosis was confirmed using karyopyknotic staining, as well as detection of DNA fragmentation and caspase 3 activation. 3. Incubation of IM-9 cells with both 0.1 micromol/L cerivastatin and 200 micromol/L clofibrate had a synergistic effect compared with 0.1 micromol/L cerivastatin alone or 200 micromol/L clofibrate alone. The magnitude of apoptosis induced by various combinations of statins and clofibrate were as follows: cerivastatin (0.1 micromol/L) + clofibrate (200 micromol/L) > atorvastatin (0.1 micromol/L) + clofibrate (200 micromol/L) > pravastatin (100 micromol/L) + clofibrate (200 micromol/L). Other fibrates (bezafibrate and clinofibrate) did not show any synergistic effect. Furthermore, karyopyknotic staining, caspase 3 activation and DNA fragmentation demonstrated synergistic pro-apoptotic effects of statin and fibrate. 4. The results of the present study suggest that simultaneous treatment with statins and clofibrate could provide improved therapeutic efficacy in leukaemia patients.

Abstract
Vascular calcification is common among hemodialysis (HD) patients and contributes to the development of peripheral arterial disease. A 57-year-old Japanese man who had been on HD for 30 years was referred to us for severe pain with multiple ulcers on his toes and fingers. He was an ex-smoker and had no diabetes mellitus. On admission, he had ulcers on his big toes bilaterally and right 2nd - 4th fingers. Peripheral pulses were strong and his ankle-brachial pressure index was above 1.3. Laboratory data were as follows: calcium 9.9 mg/dl, albumin 3.3 g/dl, phosphate 3.0 mg/dl, Ca x P product 30, and parathyroid hormone 98 pg/ml. He had a parathyroidectomy in 1998 and 1999. X-rays of his hands and legs showed diffuse subcutaneous arteriolar calcification. Angiography revealed no local stenotic lesions. Despite intensive therapies including hyperbaric oxygen therapy, painful gangrene developed on his right big toe and the pain was so intense that he could not go to sleep in a supine position. We infused intravenous sodium thiosulfate (20 g) 3 times weekly, based on previous reports. Within 4 - 5 days, he experienced rapid and dramatic symptom relief. The score of the visual analogue pain scale improved from 10/10 - 2/10. The signs of ischemia, measured by transcutaneous partial oxygen pressure and thermography, improved significantly. During the infusion of sodium thiosulfate, the patient complained of nausea, vomiting and hyperosmia. These adverse symptoms were resolved after discontinuation of the infusion. Pain relief was sustained and he could walk after 2 weeks of infusion. Our case supports the use of sodium thiosulfate as a novel therapeutic choice for critical limb ischemia with severe vascular calcification in chronic HD patients.

Abstract
BACKGROUND Video-assisted thoracoscopic (VATS) thymectomy has been applied as a surgical option for autoimmune myasthenia gravis. Prior identification and fine division of the thymic veins are critical to the prevention of unexpected severe bleeding that may require conversion to open surgery. Until recently, such bleeding could be avoided only by meticulous dissection of thymic fat tissue away from the left brachiocephalic vein (LBV). With recent advances in computed tomography (CT), multidetector-row computed tomography (MDCT) can readily be obtained and provides three-dimensional (3D) images. This study explored its value for preoperative identification of the thymic veins draining into the LBV, and thus for prevention of injury to these veins during endoscopic thymectomy. METHODS Five patients with myasthenia gravis, thymoma, or both underwent enhanced MDCT preoperatively. The thymic veins draining into the LBV were visualized using both horizontal and sagittal/coronal CT images. Then 3D images were reconstructed to enable operators to simulate endoscopic views. During each VATS extended thymectomy, the numbers and branching patterns of the thymic veins were compared with the preoperative MDCT images. RESULTS The thymic veins draining into the LBV were clearly identified with MDCT in all five patients examined. Reconstructed 3D images clearly located their courses in the thymic/fat tissue and their entry routes into the LBV, thus simulating the actual intraoperative endoscopic views. All tributaries divided during surgery were identified preoperatively with MDCT. CONCLUSIONS Location of thymic veins with MDCT can provide precise preoperative information about thymic venous anatomy. This easy and less invasive examination has the potential to make VATS thymectomy easier and safer.

Abstract
BACKGROUND AND AIM To evaluate CT findings of pulmonary alveolar microlithiasis and correlate the CT with the pathologic findings. METHODS The study included 10 patients with pathologically proven microlithiasis. Two independent observers evaluated the presence, extent and distribution of the CT findings. CT findings were compared with those at autopsy in two patients and with transbronchial biopsy in eight patients. RESULTS All patients had a myriad of calcified nodules measuring approximately 1 mm in diameter. Close apposition of the nodules resulted in areas of ground-glass attenuation and consolidation, which were the predominant abnormality on CT in all 10 patients, involving 41% +/- 16.3 (mean +/- SD) and 30% +/- 4.8 of the lung parenchyma, respectively. Calcifications were also seen along interlobular septa, bronchovascular bundles and pleura. Other findings included interlobular septal thickening, thickening of bronchovascular bundles, nodules, and subpleural cysts. There was a solid agreement between the observers for the presence (kappa value; 0.77) and extent (Spearman rank correlation; r = 0.81 to 1.0 p < 0.01) of abnormalities. Autopsy specimens demonstrated microliths in alveolar airspaces and along interlobular septa, bronchovascular bundles and pleura. Subpleural small cysts were shown to represent dilated alveolar ducts. CONCLUSION Pulmonary microlithiasis is characterised by the presence of numerous small, calcified nodules, calcifications along interlobular septa, bronchovascular bundles and pleura, ground-glass opacities, consolidation, and subpleural cysts. The cysts represent dilated alveolar ducts.

Abstract
The aim of the present study is to clarify the absorption mechanism of a drug from the kidney surface membrane in rats. We studied the absorption characteristics of phenolsulfonphthalein (PSP) and other compounds with different molecular weights after their application to the rat kidney surface in vivo, employing a cylindrical diffusion cell (i.d. 6 mm, area 0.28 cm(2)). The time course of free PSP amounts remaining in the diffusion cell obeyed first-order kinetics at a dose of 1 mg, and its rate constant k(a) was calculated to be 0.0137 min(-1). Absorption ratios of PSP in 4 h were calculated (from the amount recovered from the diffusion cell) to be 91.4, 96.4 and 97.7% at doses of 0.5, 1 and 1.5 mg, respectively. The area under the curve for the plasma concentration profile of free PSP was proportional to the application dose. It is thus suggested that the absorption process of PSP from the rat kidney surface does not approach saturation at a dose of 1.5 mg. Also, no significant difference was seen in the k(a) values within the dose range of 0.5-1.5 mg, which were estimated by curve-fitting the plasma concentration profiles of free PSP in a two-compartment model with first-order absorption. Furthermore, we examined the importance of molecular weight on the absorption from the kidney surface using fluorescein isothiocyanate-dextrans (FDs) with molecular weights of 4400 (FD-4), 11,000 (FD-10), 40,500 (FD-40) or 69,000 (FD-70), including the organic anions bromphenol blue and bromosulfonphthalein. The absorption ratios of FDs from the rat kidney surface in 6 h decreased with an increase in the molecular weight (76.1% for FD-4, 54.4% for FD-10, 11.5% for FD-40 and 3.9% for FD-70). A linear relationship was observed between k(a) and the reciprocal value of z the square root of the molecular weight of these compounds. The limit of absorption from the rat kidney surface was extrapolated to be at a molecular weight of approximately 130,000.
