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.

Objectives: This study aimed to determine the relationship between the number of board-certified physiatrists and the amount of inpatient rehabilitation delivered.Materials and Methods: We analyzed open data from 2017 in the National Database of Health Insurance Claims and Specific Health Checkups of Japan and compared the volume of inpatient rehabilitation services between prefectures to examine regional disparities. We also examined the relationship between the volume of rehabilitation services provided and the number of board-certified physiatrists.Results: The population-adjusted number of inpatient rehabilitation units per prefecture ranged from a maximum of 659,951 to a minimum of 172,097, a disparity of 3.8-fold. The population-adjusted number of board-certified physiatrists was 4.8 in the highest region and 0.8 in the lowest region, a disparity of 5.8-fold. The population-adjusted number of board-certified physiatrists was significantly correlated with the population-adjusted total number of inpatient rehabilitation units (r=0.600, P<0.001). Correlations were between the number of board-certified physiatrists and the number of rehabilitation units in cerebrovascular and orthopedic services, but not in cardiovascular, respiratory, or oncology services.Conclusion: Large regional disparities manifested in the amount of inpatient rehabilitation provided in Japan. An association was found between the number of board-certified physiatrists and rehabilitation units delivered. It may be necessary to train more BCPs in regions with fewer units to eliminate these disparities.

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.

BACKGROUND: Preventing the need for long-term care (LTC) by identifying physical function risk factors are important to decrease the LTC burden. The objective of this study was to investigate whether grip strength and/or walking speed, which are components of the frailty definition, are associated with LTC in community-dwelling older and oldest people. METHODS: The participants were 1098 community-dwelling older and oldest people who had not received LTC at the baseline. The endpoint was receiving LTC after the baseline survey. The independent variables were grip strength and walking speed, and participants were divided into two groups based on these variables. The confounding factors were age, sex, the Japanese version of the Montreal Cognitive Assessment (MoCA-J), hypertension, diabetes mellitus, stroke, joint diseases, living alone, body mass index, and serum albumin. We calculated the hazard ratio of receiving LTC using the Cox proportional hazard model. RESULTS: Among the 1098 participants, 107 (9.7%) newly received LTC during the follow-up. Regarding the physical function, only slow walking speed was significantly correlated with LTC after adjusting for all confounding factors except the MoCA-J score (HR = 1.74, 95% CI = 1.10-2.75, P = .018). However, slow walking speed was still a risk factor for LTC after adjusting for the MoCA-J score and other confounding factors (HR = 1.64, 95% CI = 1.03-2.60, P = .037). CONCLUSIONS The findings from this study may contribute to a better understanding of slow walking speed as a factor related to LTC, which might be a criterion for disability prevention and could serve as an outcome measure for physical function in older people.

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.

To screen for additional treatment targets against tongue cancer, we evaluated the contributions of extracellular signal-related kinase (ERK), AKT and ezrin in cancer development. Immunohistochemical staining showed that ERK and ezrin expressions were significantly higher in invasive squamous cell carcinoma than in carcinoma in situ. To investigate the roles of ERK and ezrin in cancer development, we used the non-woven silica fibre sheet Cellbed with a structure resembling the loose connective tissue morphology in a novel 3D culture system. We confirmed that the 3D system using Cellbed accurately mimicked cancer cell morphology in vivo. Furthermore, cell projections were much more apparent in 3D-cultured tongue cancer cell lines than in 2D cultures. Typically, under conventional 2D culture conditions, F-actin and cortactin are colocalized in the form of puncta within cells. However, in the 3D-cultured cells, colocalization was mainly observed at the cell margins, including the projections. Projections containing F-actin and cortactin colocalization were predicted to be invadopodia. Although suppressing ezrin expression with small interfering RNA transfection caused no marked changes in morphology, cell projection formation was decreased, and the tumour thickness in vertical sections after 3D culture was markedly decreased after suppressing ERK activity because both the invasion ability and proliferation were inhibited. An association between cortactin activation as well as ERK activity and invadopodia formation was detected. Our novel 3D culture systems using Cellbed™ are simple and useful for in vitro studies before conducting animal experiments. ERK contributes to tongue cancer development by increasing both cancer cell proliferation and migration via cortactin activation.

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.

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.

BACKGROUND/AIMS: Postoperative endoscopic recurrence (PER) occurs in nearly 80% of patients 1 year after ileocecal resection in patients with Crohn's disease (CD). Biological agents were more effective in reducing the rates of PER in comparison with conventional therapy, in prospective trials. The aim of this study was to compare the PER rates of biological versus conventional therapy after ileocecal resections in patients with CD in real-world practice. METHODS: The MULTIPER (Multicenter International Postoperative Endoscopic Recurrence) database is a retrospective analysis of PER rates in CD patients after ileocecal resection, from 7 referral centers in 3 different countries. All consecutive patients who underwent ileocecal resections between 2008 and 2012 and in whom colonoscopies had been performed up to 12 months after surgery, were included. Recurrence was defined as Rutgeerts' score > or =i2. The patients were allocated to either biological or conventional therapy after surgery, and PER rates were compared between the groups. RESULTS: Initially, 231 patients were evaluated, and 63 were excluded. Of the 168 patients in the database, 96 received anti-tumor necrosis factor agents and 72 were treated with conventional therapy after resection. The groups were comparable regarding age, gender, and perianal disease. There was longer disease duration, more previous resections, and more open surgical procedures in patients on biologicals postoperatively. PER was identified in 25/96 (26%) patients on biological therapy and in 24/72 (33.3%) patients on conventional therapy (P=0.310). CONCLUSIONS: In this retrospective observational analysis from an international database, no difference was observed between biological and conventional therapy in preventing PER after ileocecal resections in CD patients.

　　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.
