The effects of aging on adaptive force control of precision grip while manipulating a small object were compared between older (84.2±8.9 yrs, n=33) and young adults (19.1±0.24 yrs, n=18) from the following perspectives: (1) adaptation to an unfamiliar object with uncertain physical properties during 16 consecutive lifts ; (2) adaptation to an object with a non-slippery (sandpaper) surface during 12 consecutive lifts, followed by 12 consecutive lifts with a slippery (silk) surface ; and (3) adaptation to objects with different weights (0.49, 0.98, 1.96 and 2.94 N) during 24 lifts (6 consecutive lifts for each weight) .During each trial, grip and load forces were monitored. Safety margin force and slip force were evaluated from the data obtained.
The majority of older adults employed a considerably greater safety margin for an unfamiliar object in the initial trials than did young adults, while the minority of the older adults were able to adapt their safety margin force with a few trials, like the young adults. The older adults who overestimated the safety margin force, however, successfully adjusted their grip force to more optimal levels with repeated lifts, suggesting that the adaptive capability of grip force remained even at 90 years of age. The adaptation of older adults, however, was found to be slower (i. e., required more trials) than that of young adults. Upon encountering surface friction change, the safety margin forces in older adults were more strongly affected by the previous surface condition than those in the young adults. In addition, adaptation to a non-slippery surface seemed more difficult than that to a slippery surface with aging. Upon encountering weight change, older adults showed more difficulties in scaling their safety margin forces according to object weights.
Slower adaptation and difficulty in adaptation to the friction or weight change in older adults may reflect the agerelated decline of tactile sensitivity which impaired the signaling of frictional conditions and various discrete events in the hand. In addition, the lift repetition for force adaptation may possibly reflect the age-related deficit or slowing of central processing capacities related to grip force production.

Objective: The objective of this study was to validate the Japanese version of the STOP-Bang test for risk assessment of obstructive sleep apnea syndrome (OSAS).Methods: We retrospectively evaluated inpatients who underwent nocturnal pulse oximetry for OSAS screening at the internal medical wards.Results: One hundred and forty-four subjects were included the study, and 57 subjects who had a 3% oxygen desaturation index ≥10/hr underwent polysomnography. Seventeen and 29 subjects were diagnosed with moderate and severe OSAS, respectively. According to the receiver operating characteristic (ROC) curve analysis, the STOP-Bang test had a higher diagnostic value using a cutoff of 30 kg/m2 for BMI than using a cutoff of 35 kg/m2. A STOP-Bang score of 3 or greater had a sensitivity of 95.7% and specificity of 42.9% for detecting moderate-to-severe OSAS.Conclusion: The STOP-Bang test is a simple and useful tool for the risk assessment of OSAS.

An 81-year-old man was referred to our hospital with bilateral multiple patchy opacities on chest radiography. His chief complaints were a few months’ history of intermittent mild cough and slightly yellow sputum. Chest computed tomography (CT) showed non-segmental air-space consolidations with ground-glass opacities. Amyloid deposition with organizing pneumonia (OP) was seen in transbronchial lung biopsy (TBLB) specimens from the left S8. Three months later, the infiltration originally seen in the left lower lobe was remarkably diminished, and new infiltrations in the lingual and right lower lobes were detected on chest CT. Amyloid deposition with OP was seen in TBLB specimens from the left S4. Transthyretin was detected following immunohistochemical examination. The presence of wild-type transthyretin (ATTRwt) was proven using genetic analysis. The present report describes a rare case of ATTRwt amyloidosis associated with OP.

The aim of this study was to examine topophilia in the elderly living in mountainous areas. Topophilia, which is the geographical concept invented by Yi-Fu Tuan in 1999, is defined as the affective bond between people and place or environmental setting. A total of 120 elderly subjects living in a mountainous area responded to a standardized, validated 9-item Life Satisfaction Index K (subjective well-being) developed by Wataru Koyano and a new structured 6-item questionnaire on topophilia. Factor analyses revealed two domains of topophilia (public emotion and private emotion toward the living place). Public emotion was the emotion of being hard to leave the living place. Private emotion was the emotion of not loving the living place. There were areas where the elderly had a lesser degree of attachment toward the present state of the elderly could hardly have a sense of well-being and attachments to the current domicile. It is considered that not only physical but also mental approach is necessary to support the daily life of the elderly living in the mountainous area. Also, we examined the influences of aging and the living place on a subjective well-being and topophilia. There was no significant correlation between age and subjective well-being, but there was significant positive correlation between age and the degree of topophilia (r=0.234, p‹0.01). On the other hand, the degree of subjective well-being by the place of residence was significantly different (p‹0.001; ANOVA), and the degree of topophilia by the place of residence was not significantly different. These findings suggest that subjective well-being is not influenced by age but influenced by the place of residence, and topophillia is not influenced by the place of residence but influenced by age.

OBJECTIVESThe aim of this study was to survey the prevalence of fascioliasis in slaughtered cattle in order to provide breeders with feedback which may prevent cattle fascioliasis, as well as human fascioliasis.
METHODSThe results of meat inspection and the information extracted from the Discriminative Data Base on Individual Livestock in Japan were analyzed statistically in 6,224 cattle slaughtered at the Tsuyama Abattoir during the fiscal year 2002.
RESULTSThe age-adjusted fascioliasis and cholangitis rates of all cattle were 2.0% and 7.2%, respectively. When analyzed by cattle breed, both rates were significantly higher in Japanese native cattle than in Holstein or Jersey (Chi-square test, p<0.01). The cattle raised in Okayama Prefecture, Tochigi Prefecture and Shimane Prefecture were significantly different from cattle raised in other prefectures in the age-adjusted fascioliasis and cholangitis rates.
CONCLUSIONThe age-adjusted fascioliasis and cholangitis rates of all cattle can be considered as nationwide rates for slaughtered cattle. The results of the comparisons suggest that cattle fascioliasis is related to feeding with rice straw and that the measures to prevent cattle fascioliasis might differ a mong prefectural governments.

Objective: Health information, including the labelling, must be presented in a manner that is easily understandable to consumers. In recent years, the European Union and the United States have introduced standards for providing health information in a way that is easy for consumers to understand. The Clear Communication Index (CCI) published by the Centers for Disease Control and Prevention (CDC) is a useful tool for this purpose. Unfortunately, there is no such tool in Japan. Therefore, focusing on the package labelling of foods with functional claims (FFCs) sold in Japan, we constructed a Functional Clear Communication Index (F-CCI) and evaluated the FFCs.Methods: The F-CCI was developed by six people, including university staff with pharmacist qualifications and public health experts, by referring to the CDC CCI. The evaluation of FFCs using the F-CCI was performed using the Delphi method, which is one of the formal consensus-building methods in the field of health and medical information. The evaluation was conducted by three qualified pharmacists on five FFC products, and the degree of internal agreement among the evaluators was calculated using Fleiss’ κ.Results: The F-CCI consisted of 18 items that assessed the FFC characteristics. After assessing the labelling of FFCs using the F-CCI, the scores of all the materials ranged between 70 and 80% on the F-CCI, and none achieved 90%, which was considered the acceptable standard (overall κ value_ 0.865). Moreover, it was clear that the ‘readability’ and ‘understandability’ of the labelling were inadequate.Conclusion: The F-CCI developed in this study for the objective evaluation of the labelling of FFC products will act as a tool that will subsequently lead to the proper understanding and use of FFCs by consumers. Further efforts are needed to build and disseminate such tools and user-friendly ways of providing relevant information.

Objective:It is necessary to obtain appropriate drug information (DI)so that appropriate medical care is provided for the consumers,patients. Thorough studies have not been done on institutions that offer DI for patients in Japan and the state of its dissemination. The purpose of this study is to find levels of recognition of the institutions providing medical information and the actual state of its usage.Method:In order to find the levels of recognition of the institutions that provide DI to general consumers and the state of usage of the information provided by them,we conducted questionnaire surveys using online panels. We also conducted a study to find subjective comprehension on DI by the panels. The surveys were conducted twice using the same questionnaire in order to robust the outcomes of the study.Results:We received 1,095 valid responses from the first survey and 1,086 from the second survey respectively. No significant differences were found between the two surveys. Although the levels of recognition vary for the four representative public institutions providing DI,DI provided by these institutions has been barely utilized by the respondents. As the sources of DI that have been used most,almost the same numbers of respondents replied that they used Internet search engines to access them in addition to medical doctors and pharmacists. Regarding the levels of comprehension for the provided DI,the respondents tended to have shown high levels of understanding on maintaining medication compliance,but low on safety information. There was a positive correlation between age and the understanding of the DI.Conclusion: The study implies that the environment to provide DI for patients still needs to be improved, and the respondents didnʼt understand DI enoughly. Therefore,it is necessary to study further for the creation and communication of truly user-friendly DI.

Objectives: It is important for patients to make correct use of drug information (DI) to promote the proper use of medicines. Many patients use the Internet to find DI, but awareness about the websites of public institutions that provide DI is low. This study aimed to identify the actual use of the Internet for DI and associated problems to inform development of a comprehensive DI website for patients.Method: Patients with diabetes were set as a model case for patients who take medicines and need DI. A questionnaire survey was conducted among patients with diabetes who visited community pharmacies in Kagoshima City from March 2019 to October 2019. The survey covered Internet use, DI needs, methods of sourcing DI, and problems obtaining DI via the Internet.Results: There were 349 valid respondents (median age 64 years), of which 52.1% used the Internet at least once a week. Around half of the Internet users searched for DI on the Internet. More than half of these respondents chose a DI acquisition site because it “appeared at the top of search results” and was “easy to understand.” However, around half of these respondents felt that “there is too much information on the internet and I don’t know what is correct.”Conclusion: This study suggests that older patients with a long history of diabetes use the Internet to obtain DI. However, patients face various problems accessing DI via the Internet. It may be necessary to construct a comprehensive website that is easy to use and enhance public health literacy to support the proper use of medicines by patients.
