加速度と接触力センサーを用いた手指運動の可視化と評価 : POC試験
The 10-s grip and release is a method to evaluate hand dexterity. Current evaluations only visually determine the presence or absence of a disability, but experienced physicians may also make other diagnoses. In this study, we investigated a method for evaluating hand movement function by acquiring and analyzing fingertip data during a 10-s grip and release using a wearable sensor that can measure triaxial acceleration and strain. The subjects were two healthy females. The analysis was performed on the x-, y-, and z-axis data, and absolute acceleration and contact force of all fingertips. We calculated the variability of the data, the number of grip and release, the frequency response, and each finger's correlation. Experiments with some grip-and-release patterns have resulted in different characteristics for each. It was suggested that this could be expressed in radar charts to intuitively know the state of grip and release. Contact-force data of each finger were found to be useful for understanding the characteristics of grip and release and improving the accuracy of calculating the number of times to grip and release. Frequency analysis suggests that knowing the periodicity of grip and release can detect unnatural grip and release and tremor states. The correlations between the fingers allow us to consider the finger's grip-and-release characteristics, considering the hand's anatomy. By taking these factors into account, it is thought that the 10-s grip-and-release test could give us a new value by objectively assessing the motor functions of the hands other than the number of times of grip and release.博士(医学)・甲第795号・令和3年6月25日© 2021 by the authors.

Comparison of quality of life between elderly and non-elderly adult residents in Okuma town, Japan, in a post-disaster setting
With the growing elderly population who are susceptible to poor health, improvement of their quality of life is essential. In the post-disaster setting of the 2011 Fukushima Dai-ichi nuclear power plant (FDNPP) accident, affected municipalities such as Okuma town commenced their recovery processes and lifted evacuation orders in 2019. This study examines the differences in self-reported mental and physical health status, social functioning, risk perception, and intention to return between elderly (age ≥65 years) and non-elderly (age 20–64 years) residents. Questionnaires were distributed to current residents and evacuees of Okuma. Results revealed that the elderly had a 1.4 times higher odds ratio (95%CI 1.0–1.8, p = 0.034) for having anxiety regarding radiation-related health effects on future generations and a 1.3 times higher odds ratio (95%CI 1.1–1.5, p = 0.001) for wanting to know about the release of FDNPP-treated water into the environment than the younger group. Elderly residents also demonstrated a 2.2 times higher odds ratio for reporting poor physical health than younger residents. Clearing misconceptions and disseminating coherent information will reduce risk perception among this group. Further in-depth research regarding the disposal of FDNPP-treated water and its perceived risks is required. Health promotion through the encouragement of social participation, improvement of surroundings to facilitate healthy behaviors, and enhanced access to health services will improve the quality of life of elderly Okuma residents
Occupational Difficulties of Disaster-Affected Local Government Employees in the Long-Term Recovery Phase after the Fukushima Nuclear Accident: A Cross-Sectional Study Using Modeling Analysis
Local government officials play a central role in post-disaster community reconstruction. However, few studies have eported on the actual difficulties during a complex disaster involving a nuclear accident. A self-rated questionnaire survey was administered to a total of 583 public employees in four municipalities around the Fukushima Daiichi Nuclear Power Station. The relationship between universal occupational factors and radiation disaster-specific factors on job satisfaction and intention to leave the job due to radiation anxiety was evaluated using structural equation modeling. The results showed that interpersonal problems (β = -0.246) and service years (β = ‐0.127) were related to job satisfaction, whereas radiation-specific factors were not related to job satisfaction, and only to the intention to leave work due to radiation anxiety. A sense of coherence was associated with job satisfaction (β = 0.373) and intention to leave work due to radiation anxiety (β= -0.182), and it served as a moderator of the universal occupational factors and the radiation disaster-specific factors. Therefore, it is suggested that outcomes could be improved through increased stress coping capacity by providing support for relationships and radiation risk communication to public employees during the disaster recovery period
Risk Perception of Health Risks Associated with Radiation Exposure among Residents of Okuma, Fukushima Prefecture
Ten years have passed since the Great East Japan Earthquake and the subsequent Fukushima Daiichi nuclear power plant accident on 11 March 2011. Okuma is a town hosting the Fukushima Daiichi nuclear power plant. The evacuation order for Okuma was partially lifted in April 2019. To clarify factors associated with risk perceptions of radiation among the residents of Okuma, we conducted a questionnaire survey in January 2021. Our results revealed that resident anxieties regarding the health effects of radiation exposure from living in Okuma were independently associated with positive PCL-Specific score, recognition of the consultation services with radiation experts in the municipal government of Okuma, and planned request for consultation service regarding radiation exposure by radiation experts, along with being female and living with a child. It is important for radiation experts to promote periodic communication of risks with individuals on a small scale to provide accurate information about the health effects of radiation and to provide maternal and child healthcare services and support regarding child-rearing and radiation exposure, to reduce concerns about radiation exposure and facilitate healthy living and wellbeing in Okuma
Evaluation of Residents’ Timing of Return to or New Settlement in Kawauchi Village, at 10 Years after the Fukushima Daiichi Nuclear Power Plant Accident
Kawauchi village in Fukushima prefecture was affected by the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, and residents had to evacuate from their hometown in 2011. This study clarified the timing and related factors with regard to residents returning to or newly settling in Kawauchi. A survey was conducted using a questionnaire, from February to March 2021, with assistance from the Kawauchi village office and post office. Of the 374 residents, 170 (45.5%) had returned to or newly settled in Kawauchi within the past 2 years (group 1), 84 (22.5%) in the past 2–5 years (group 2), and 99 (26.5%) after more than 5 years (group 3) following the evacuation order. An additional 21 residents (5.5%) who had lived in Kawauchi at the time of the FDNPP had not yet returned (group 4). Compared with the other groups, residents in group 1 were more satisfied with their current lives and were coping better with stress. Even though they had experienced a serious nuclear disaster, residents of Kawauchi village who returned to their hometown in the early phase had a high sense of satisfaction with their current life one decade after the FDNPP accident

Effect of Hydrogen Peroxide and High Glucose on the Glucose Metabolism of Lymphoma-derived U937 Cells
Our study aimed to clarify specific oxidative stress and glucose metabolic disorders in hemodialysis patients, by examining hydrogen peroxide (H2O2) - and high glucose-induced oxidative stress, glucose transport and the failure of glycolysis. As an in vitro blood cell model of end-stage renal disease (ESRD) in patients with diabetes, human monocytic U937 cells of malignant lymphoma origin were exposed to high glucose (28.9mM) for 6 days, with 5mM H2O2 added on the last day. The generation of intracellular reactive oxygen species (ROS), glucose levels, lactate levels, AMP-activated protein kinase (AMPK) activity and Glut4 levels were examined. Exposure of U937 cells to H2O2 resulted in a significant increase in intracellular ROS generation and glucose levels. Under high glucose conditions, treatment with H2O2 significantly promoted these actions. In H2O2-induced U937 cells, AMPK activity and Glut4 levels were significantly increased, but lactate and pyruvate levels were significantly decreased. Thus, exposure of U937 cells to H2O2 and a high glucose load promoted an increase in intracellular ROS, and exposure to H2O2 induced increased glucose transport and high intracellular glucose due to reduced glycolytic metabolism. This suggests that reduced glycolytic metabolism might be induced in states of high oxidative stress in hemodialysis patients with diabetes
Assessment of Radiation Risk Perception and Interest in Tritiated Water among Returnees to and Evacuees from Tomioka Town within 20 km of the Fukushima Daiichi Nuclear Power Plant
In this study, we aimed to investigate radiation risk perception, mental health, and interest in tritiated water among evacuees from and returnees to Tomioka town, Japan, as well as to evaluate the intention to return (ITR) among evacuees living inside and outside Fukushima Prefecture. Of the 1728 respondents, 318 (18.4%) and 1203 (69.6%) participants reported living outside and inside Fukushima Prefecture, and 207 (12.0%) reported living in Tomioka. The ITR was not significantly different between those who lived inside and outside the prefecture among the evacuees. Similarly, there were no significant differences in radiation risk perception, mental health, and interest in tritiated water. However, the evacuees were independently associated with a motivation to learn about tritiated water (OR = 1.242, 95%Cl: 1.041–1.438, p = 0.016), reluctance to consume food from Tomioka (OR = 1.635, 95%Cl: 1.372–1.948, p < 0.001), and concern that adverse health effects would occur because of the Fukushima Daiichi Nuclear Power Plant accident (OR = 1.279, 95%Cl: 1.055–1.550, p = 0.012) compared to returnees, according to logistic regression analysis. Interestingly, the returnees were found to have better mental health but lower life satisfaction than the evacuees. These findings suggest the importance of ongoing risk communication about radiation exposure and tritiated water among residents regardless of their place of residency
Pleiotropic Effects of Linagliptin Monotherapy on Levels of Nitric Oxide, Nitric Oxide Synthase, and Superoxide Dismutase in Hemodialysis Patients with Diabetes
Linagliptin is an anti-diabetic drug and the only bile-excreted dipeptidyl peptidase-4 inhibitor. Malnutrition-inflammation-atherosclerosis syndrome is an important prognostic factor for hemodialysis patients, and we previously reported anti-inflammatory effects of linagliptin in hemodialysis patients with diabetes. Inflammation can accelerate oxidative stress, vasoconstriction, and platelet aggregation. However, few studies have investigated the pleiotropic effects of linagliptin treatment on inflammation in hemodialysis patients. In this study, we have extended our previous investigations of these effects in a longer and more thorough follow-up of hemodialysis patients with diabetes. We examined 20 hemodialysis patients with diabetes who were not receiving oral diabetes drugs or insulin therapy and who exhibited inadequate glycemic control (glycated albumin levels>20%). Linagliptin (5mg) was administered daily, and we evaluated the patients’ superoxide dismutase, 8-hydroxydeoxyguanosine, nitric oxide, nitric oxide synthase, and asymmetric dimethylarginine levels in serum at baseline and after 1, 3, and 6 months of treatment. After 6 months of treatment, superoxide dismutase levels had significantly decreased from 8.8±0.5U/ml to 7.0±0.5U/ml. Nitric oxide synthase levels were significantly increased at 3 and 6 months (maximum, 94.2±13.2µg/ml; baseline, 31.6±5.5µg/ml). After 3 months of treatment, nitric oxide levels had significantly increased from 64.5±6.6µmol/l to 104±15.4µmol/l, and remained significantly elevated at 6 months. Asymmetric dimethylarginine and 8-hydroxydeoxyguanosine levels did not change during the 6-month treatment course, and no patients exhibited hypoglycemia or other significant adverse effects. Linagliptin treatment significantly changed various markers of inflammation relevant to the atherosclerosis in malnutrition-inflammation-atherosclerosis syndrome. Therefore, linagliptin monotherapy has pleiotropic effects on inflammation in hemodialysis patients with diabetes, and may improve their prognosis
