Community-dwelling elderly are likely to fall even after ophthalmological surgery. To identify the association between falls and ophthalmological surgery and screening experiences among the community-dwelling elderly in Japan, a cross-sectional descriptive study examined 159 community-dwelling people aged ≥ 65 years about an extensive physical assessment, health status, experience of falls, and ophthalmic situations. In this city, the study identified an association between falls and both ophthalmological surgery experience and voluntary attendance at ophthalmic screening among the community-dwelling elderly. Japanese public health nurses should be a bridge between community-dwelling elderly and ophthalmologists in the community to promote attendance at ophthalmic screening. © 2017 Taylor & Francis.

Chronic kidney disease (CKD) patients have an extremely increased risk of fragility fractures, but the underling pathophysiological mechanisms remain obscure. Recently, the progresses of analysis technology have revealed the changes of bone quality in CKD condition. In particular, we can observe the characteristic changes of bone microarchitecture and bone chemical compositions in both human bone biopsy samples and experimental animal bones. Here, I will provide a short review on these bone quality factors and discuss on the relationship between bone quality and fracture in CKD patients.

Bone fragility is a complication of chronic kidney disease (CKD). Patients on dialysis have higher risk of fracture than the general population, but the reason remains obscure. Bone strength is determined by bone mass and bone quality. Although factors affecting bone quality include microarchitecture, remodeling activity, mineral content, and collagen composition, it remains unclear which factor is critically important for bone strength in CKD. We conducted an in vivo study to elucidate the factors that reduce bone mechanical property in CKD. Rats underwent thyroparathyroidectomy and progressive partial nephrectomy (TPTx-Nx). Bone mechanical property, bone mineral density (BMD), and cortical bone chemical composition (all in femur) as well as histomorphometry (in tibia) were determined. The storage modulus, which is a mechanical factor, was reduced in CKD model rats compared with controls that underwent thyroparathyroidectomy alone (TPTx). There were no differences in BMD and histomorphometric parameters between groups. However, cortical bone chemical composition differed: mineral to matrix ratio and carbonate substitution increased whereas crystallinity decreased in TPTx-Nx. In addition, enzymatic crosslinks ratio and pentosidine to matrix ratio also increased. These changes were significant in TPTx-Nx rats with most impaired renal function. Stepwise multiple regression analysis identified mature to immature crosslink ratio and crystallinity as independent contributors to storage modulus. Deteriorated bone mechanical properties in CKD may be caused by changes in chemical composition of the cortical bone, and is independent of BMD or cancellous bone microarchitecture. © 2011 Elsevier Inc.

The accident at the Fukushima Dai-ichi nuclear power plant released a large quantity of radioactive iodine and caesium into the environment. In terms of radiological protection, the evacuation and food restrictions that were adopted in a timely manner by the authorities effectively reduced the dose received by people living in the affected area. Since late March, the transition from an emergency to an existing exposure situation has been in progress. In selecting the reference exposure levels in some areas under an existing exposure situation, the authorities tried to follow the situation-based approach recommended by the ICRP. However, a mixture of emergency and post-emergency approaches confused the people living in the contaminated areas because the reactor conditions continued to be not completely stable. In deriving the criteria in an existing exposure situation, the regulatory authority selected 20 mSvy -1. The mothers in the affected area believed that a dose of 20 mSvy -1 was unacceptably high for children since 1mSvy -1 is the dose limit for the public under normal conditions. Internet information accelerated concern about the internal exposure to children and the related health effects. From some experiences after the accident the following lessons could be learned. The selection of reference doses in existing exposure situations after an accident must be openly communicated with the public using a risk-informed approach. The detriment-adjusted nominal risk coefficient was misused for calculating the hypothetical number of cancer deaths by some non-radiation experts. It would not be possible to resolve this problem unless the ICRP addressed an alternative risk assessment to convey the meaning and associated uncertainty of the risk to an exposed population. A situation-based approach in addition to a risk-informed approach needs to be disseminated properly in order to select the level of protection that would be the best possible under the prevailing circumstances. A dialogue between radiation and other risk experts such as those dealing with chemical exposures is now needed. © 2012 IOP Publishing Ltd.

The Task Group (TG) of Committee 4 was created to update the International Commission on Radiological Protection (ICRP) Publications 109 and 111 in light of the lessons from Fukushima, recent international developments concerning the protection of people in emergency exposure situations, and people living in long-termcontaminated areas after a nuclear accident or a radiation emergency. An important aspect of the TG's approach focuses on clarifying the consequences of the introduction of the situation-based approach to implementation of radiological protection that was introduced in ICRP Publication 103 in place of the previous approach based on the distinction between practices and interventions. The TG focused its reflection on several issues revealed by the Fukushima accident in relation to the justification and optimization of emergency decisions, the characterization of the radiological situation, the protection of emergency and recovery responders, the decontamination and waste management strategies, the management of contaminated foodstuffs and commodities, the shift from the emergency to the existing exposure situation, and the co-expertise process to develop radiological protection culture among the affected population. © 2016 Health Physics Society.

Antiseptic agents can cause skin irritation and lead to severe problems, especially for individuals with atopic diatheses. We investigated the effect of 4 different antiseptic agents using an atopic dermatitis (AD) model mouse. NC/Nga mice were subcutaneously injected with mite allergen (Dp) to induce AD-like skin lesions (ADSLs), and an application of 0.2% (w/v) benzalkonium chloride (BZK), 10% (w/v) povidone-iodine (PVP-I), 80% (v/v) ethanol (Et-OH), or 0.5% (v/v) chlorhexidine gluconate (CHG) was applied to the ear envelope. BZK induced a significant increase in the severity of the clinical score, infiltration of inflammatory cells, local expression of inflammatory cytokines in subcutaneous tissue, and total serum immunoglobulin (Ig) E. PVP-I increased the clinical score, number of mast cells, and production of inflammatory cytokines, and total serum IgE. Et-OH increased the clinical score and number of inflammatory cells, but showed no effect on serum IgE levels. No differences in any parameters were observed between CHG and the vehicle. Collectively, the results suggest the severity of the ADSL was related in part to the strength of the immunoreaction. These findings suggest that CHG could offer the lowest risk of inducing ADSL in individuals with atopic dermatitis and that medical staff and food handlers with AD could benefit from its use. © Ivyspring International Publisher.

Aims: The purpose of this study was to investigate the relationship between inappropriate views on suicide, such as it being a personal choice, inevitable, unpreventable, and permissible, with demographic variables and the feeling of shame in seeking help among the general population. Methods: A self-administered questionnaire on mental health and suicide was distributed to all residents aged 40-74 in four areas in Oita Prefecture, Japan, and 4487 responded. The association of seven inappropriate views on suicide with demographic variables was examined by multiple logistic analyses. The association between feeling shame in seeking help with demographic variables and the above views on suicide was similarly analyzed. Results: Inappropriate views on suicide were associated with gender (i.e. men). Some of these views also correlated with age, never having been married, and living in rural areas or areas with high suicide mortality rates. Multivariate analysis revealed that feeling shame in seeking help when distressed was associated with being aged 70-74, living in rural areas or areas with high suicide mortality rates, the view on suicide as a matter of self-choice, and a pessimistic view toward life. Conclusion: These findings suggest that inappropriate views on suicide adversely affect coping strategies and mental health. Suicide prevention programs aimed at improving mental health literacy in a community should take into consideration the characteristics of elderly male residents. © 2012 The Author.

Sleep and Biological Rhythms | Year: 2016

Too much noise disturbs sleep, as well known. The number of persons affected by community noise is estimated to be huge. This paper summarizes the recommendation by WHO (1999) and the following international documents, and introduce new data and debate. First, we should choose noise descriptors to study and to regulate noise-induced sleeplessness taking account of (1) whether we want to focus on continuous noise or intermittent noise, and (2) whether we want to focus on noise prediction or ecological measurement. LAeq (A-weighted sound equivalent level) at sleep period well predicts sleep disturbance in general. Since intermittent noise is more likely to disturb sleep than continuous noise, even if their LAeq is the same, LAmax and LAE are also used. Second, we should determine sleep descriptors such as EEG, actigraphy, and questionnaires. The descriptors should be chosen, in consideration of burdens to subjects and time-scale that should be matched with noise assessment. Based on the dose–response relationship between community noise and sleep disturbance, WHO (1999) recommended that indoor sound level should be LAeq of 35 dB or below for the general population from the aspect of health sciences. WHO Regional Office for Europe (2004), however, proposed much more strict guidelines, taking the recent studies on community noise and cardiovascular diseases in the general population. Most of the data were, however, cross-sectionally obtained, and causality cannot be determined. As a result, intensive debate emerged whether or not the reported effects are meaningful and all the effects are impermissible, reflecting the difference between European view of health and US pragmatic position. On the other hand, effects of ultra-low-frequency sound from wind turbine plants on sleep and health seem negligible, although audible noise from wind turbine can disturb sleep among residents. Individual difference in sensitivity to noise and effects of daytime noise on night/shift-workers should be further investigated. If they can be clarified, this should be systematically reflected to the exposure assessment. © 2016, Japanese Society of Sleep Research.

Abnormalities in bone turnover, mineralization, and volume represent one of the three components of chronic kidney disease-related mineral and bone disorder (CKD-MBD). The risk of hip fracture is considerably high, while the risk of spinal compression fracture may not be more elevated among CKD patients than in general population. The relationship between bone fracture and bone mineral density in CKD patients is more complex than in those without kidney disease. An increase in the rate of falls has been reported to be a major cause of high hip fracture risk among CKD patients; however, it certainly is not the only underlying mechanism. Abnormal parathyroid function is not likely to be a major cause of hip fracture among CKD patients. In experimental CKD animals, mechanical elasticity properties of long bones showed an inverse correlation with kidney function. The deterioration of bone elasticity showed a significant correlation with bone biochemical changes. Of note, administration of the oral absorbent AST-120 was capable of preventing both changes. These findings suggest that uremic toxins cause a deterioration of bone material properties, and changes in material properties disturb bone elasticity. This disease concept cannot be considered to be a direct consequence of CKD-MBD. We therefore would like to call it 'uremic osteoporosis'. This entity may be a major cause of increased hip fracture risk among CKD patients. © 2013 International Society of Nephrology.

This paper describes the experiences of, and issues with, recovery management following the accident at Fukushima Daiichi nuclear power plant. The Fukushima accident has brought about socio-economic consequences with inevitable changes to daily life, as well as psychological effects. There is heightened concern amongst the population about the risk and effects of radiation at low doses. Experience has shown that the direct involvement of the affected population and local professionals is a decisive factor for management of the recovery phase. The radiological protection system of the International Commission on Radiological Protection (ICRP) seems to be relevant to the recovery requirements of the Fukushima accident, although some problems remain in implementation. Reference levels could play a role in improving the situation by requiring an iterative optimisation process. The Fukushima experience indicated that a routine, top-down approach using radiological criteria alone was unable to deal with the complexity of the problems, and that stakeholder engagement should be explored. The technical knowledge gap between radiation experts and the public caused a lot of confusion. Experts should understand the ethical values attached to recovery, and ICRP should be more active in promoting trustworthy radiological protection advice. © The International Society for Prosthetics and Orthotics Reprints and permissions: sagepub.co.uk/journalsPermissions.nav
