This study examined whether participation in an art project was associated with higher social capital (SC). We conducted a questionnaire survey from November 2021 to March 2022 among residents aged 20 years or older of Naoshima, an island in Kagawa Prefecture, Japan. Before the survey, the Setouchi Triennale had been held on Naoshima four times, starting in 2010. We calculated propensity scores for Triennale participation and performed propensity score matching. We then compared cognitive and structural SC by Triennale participation and found significant differences, respectively. We adopted a conditional ordered logistic regression analysis with propensity score matching for cognitive or structural SC, and found adjusted odd ratios of 2.913 (95%CI, 1.846-4.596) for cognitive SC and 4.535 (95%CI, 2.839-7.244) for structural SC. Our findings suggest that Triennale participation enhanced the cognitive aspect of SC while also building structural SC.

EGFR Mutation is a Prognostic Factor in Lung Cancer Patients with Pleural Dissemination Detected During or After Surgery. International journal

Annals of surgical oncology 30 ( 11 ) 6697 - 6702 2023.10

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Primary lung tumors are sometimes resected when either pleural dissemination (PD) or malignant pleural effusion (MPE) exists. This study clarified the prognostic factors for non-small cell lung cancer (NSCLC) with either PD and MPE, or both, detected during or after surgery. PATIENTS AND METHODS: We examined patients with NSCLC from a multicenter database who had either PD, MPE, or both, detected during or after surgery between 2005 and 2015. Hazard ratios and 95% confidence intervals were estimated using the Cox proportional hazards model adjusted for potential confounding factors. RESULTS: Among 9463 registered patients, PD, MPE, or both, were found in 114 patients with NSCLC during or after surgery. Primary tumor resection and exploratory thoracotomy were performed in 65 and 49 patients, respectively. In univariate analysis, adenocarcinoma, clinically undetected lymph node metastasis (c-N0 or unknown), EGFR mutation, and combination of chemotherapy or tyrosine kinase inhibitors after surgery were better prognostic factors for overall survival (OS), whereas in the multivariate analysis, adenocarcinoma, clinically undetected lymph node metastasis, and EGFR mutation were favorable independent prognostic factors in OS. Additionally, limited to patients with EGFR mutation, patients with primary lung tumor resection showed a significantly better 5-year OS than those with exploratory thoracotomy (86.4 vs. 44.8%; p < 0.001). CONCLUSION: Our findings show that surgical resection of primary tumors could improve the prognosis of patients with PD, MPE, or both, detected during or after surgery when the tumors harbor an EGFR mutation.

Otology & neurotology : official publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology 44 ( 7 ) 737 - 741 2023.8

Language：English Publishing type：Research paper (scientific journal)

OBJECTIVE: To clarify whether age impacts the development of endolymphatic hydrops (ELH) in neurotologic patients. Documentation of ELH in living patients on magnetic resonance imaging (MRI) allows analysis of patient age and formation of ELH, which is impossible by means of postmortem temporal bone pathology. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Fifty patients (100 ears) with top 3 diagnoses of definite Menière's disease, delayed ELH, or probable Menière's disease. INTERVENTIONS: Endolymph MRI after intravenous gadolinium injection and pure-tone audiometry. MAIN OUTCOME MEASURES: Cochlear and vestibular ELH confirmed by MRI. RESULTS: The prevalences of ears showing both cochlear and vestibular ELH were similar among age groups <30 years (30%), 30-59 years (25.9%), and ≥60 years (34.4%; p > 0.05; χ2 test). Using logistic regression modeling, mean hearing level at the six frequencies was positively associated with a higher risk of cochlear ELH (odds ratio, 1.3; 95% confidence interval, 1.1-1.5 per 10-dB increment). In the same regression model, age did not impact the outcome of cochlear ELH (odds ratio, 1.0; 95%confidence interval, 0.7-1.4 per 10-year increment). Age did not differ among ears with no ELH (mean ± standard deviation age, 48.6 ± 14.4 yr), ears with only cochlear ELH (59.3 ± 10.7 yr), ears with only vestibular ELH (50.4 ± 16.9 yr), or ears with both cochlear and vestibular ELH (51.5 ± 18.4 yr; p > 0.05, analysis of variance). CONCLUSION: Chronological age was not associated with the formation of ELH. Aging per se may not be associated with the development of ELH in neurotologic patients.

No epidemiological studies have examined the health effects of daily bathing in radon hot springs. In this cross-sectional study, we investigated the associations between radon hot spring bathing and health conditions. The target population was 5,250 adults ≥ 20 years old in the town of Misasa, Japan. We collected information about the participants' bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Surgical resection of esophageal cancer is frequently performed to achieve a complete cure. However, the postoperative recurrence rate is 36.8-42.5%, leading to poor prognosis. Radiation therapy has been used to treat recurrences; solitary recurrence has been proposed as a prognostic factor for radiation therapy, though its significance is unclear. 18F-fluorodeoxyglucose positron emission tomography is a highly accurate diagnostic modality for esophageal cancer. This retrospective study aimed to analyze the outcomes of solitary postoperative recurrences of esophageal squamous cell carcinoma diagnosed with 18F-fluorodeoxyglucose positron emission tomography and treated with definitive radiation therapy. METHODS: We examined 27 patients who underwent definitive radiation therapy for single or multiple postoperative recurrences of esophageal squamous cell carcinoma between May 2015 and April 2021. 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed within 3 months before the commencement of radiation therapy. Kaplan-Meier, univariate, and multivariate analyses were performed to examine the overall survival and identify potential prognostic factors. RESULTS: The 1-, 2-, and 3-year overall survival rates were 85.2%, 62.6%, and 47.3%, respectively, and solitary recurrence was the only significant factor associated with overall survival (P = 0.003). The 1-, 2-, and 3-year overall survival rates in patients with solitary recurrence were 91.7%, 80.2%, and 80.2%, respectively, and in patients with multiple recurrences they were 80.0%, 50.3%, and 25.1%, respectively. Multivariate analysis also showed solitary recurrence as a significant factor for overall survival. CONCLUSIONS: When diagnosed with 18F-fluorodeoxyglucose positron emission tomography/computed tomography, solitary recurrence appears to have a more favorable prognosis than multiple recurrences.

Nobuyoshi Matsuki, Etsuji Suzuki, Toshiharu Mitsuhashi, S V Subramanian, Soshi Takao, Takashi Yorifuji

Journal of integrative and complementary medicine 2023.6

Language：English Publishing type：Research paper (scientific journal)

Introduction: The association between complementary and alternative medicine (CAM) use and other health-related behaviors is an important issue. A previous study reported that complementary medicine use is related to greater use of cancer screening, whereas alternative medicine use is related to lower use of cancer screening. Given the sparse evidence from Japan, we aimed to examine the association of CAM use with cancer screening and medical checkups. We used a repeated cross-sectional survey of a nationally representative sample of Japanese people and conducted age-period-cohort analysis. Methods: The study population was 68,217 of 83,827 individuals observed from 2001 to 2013 who received cancer screening. CAM users were defined as individuals who received acupuncture, moxibustion, anma/massage/shiatsu, or judo therapy for their most worrisome symptom. The outcomes of interest were receiving stomach, lung, colorectal, uterine, and breast cancer screenings and medical checkups. Using crossclassified multilevel logistic regression models, we estimated odds ratios (ORs) and 95% credible intervals (CIs) for cancer screening and medical checkups. Results: For CAM users of complementary medicine, the adjusted ORs for stomach, lung, and colorectal cancer screening were 1.40 (95% CI: 1.35-1.44), 1.37 (95% CI: 1.34-1.40), and 1.52 (95% CI: 1.49-1.54), respectively. We found similar results for uterine and breast cancer screening, and medical checkups. Conclusions: Irrespective of whether they use CAM, CAM users in Japan tend to receive a variety of cancer screenings and medical checkups.

Tomoka Kadowaki, Naomi Matsumoto, Etsuji Suzuki, Toshiharu Mitsuhashi, Soshi Takao, Takashi Yorifuji

Acta Paediatrica 112 ( 1 ) 106 - 114 2023.1

Language：English Publishing type：Research paper (scientific journal) Publisher：Wiley

AIM: A number of studies have indicated the potential benefits that breastfeeding has on reducing childhood obesity, but few studies have evaluated the effect on adolescent obesity. We examined the association between breastfeeding and overweight or obesity at 15 years of age using data from a large nationwide longitudinal study launched by the Japanese Government in 2001. METHODS: We analysed data for 26 164 participants with known infant feeding practices at 6 months of age, namely the duration of breastfeeding or formula feeding. Overweight or obesity at 15 years of age were calculated based on the subject's self-reported height and weight. Multinomial logistic regression analysis adjusted the data for child factors, namely sex, siblings, birth weight and physical activity clubs and the maternal factors of age, educational attainment and smoking status. RESULTS: Formula feeding was associated with an increased risk of overweight or obesity at 15 years of age. The adjusted odds ratios (95% confidence intervals) were 0.99 (0.89-1.09) for partial breastfeeding and 1.23 (1.02-1.48) for formula feeding, when exclusive breastfeeding was the reference category. CONCLUSION: Breastfeeding during infancy had potential benefits for overweight or obesity among 15-year-old adolescents. Our results provide further evidence of the importance of breastfeeding.

Differential association of frailty with the incidence of mild and severe disability in older people: A 3-year cohort study. International journal

Akikazu Hagiyama, Soshi Takao, Rumi Matsuo, Takashi Yorifuji

Annals of geriatric medicine and research 2022.12

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Frailty is associated with the incidence of disability in older people, but few studies investigated differences in the association of frailty with mild and severe disability by Japanese long-term care insurance certification. This study investigated the association of frailty with the incidence of mild and severe disability separately. METHODS: This was a retrospective cohort study for 3 years. The participants were community-dwelling people aged ≥ 65 in Okayama City. We assessed frailty status using the Kihon Checklist and defined outcomes as mild and severe disability in long-term care insurance certifications. Multinomial logistic regression analysis was used to investigate the association of frailty with the incidence of mild and severe disability. RESULTS: A total of 36043 participants were analyzed. For mild disability, the odds ratios (ORs) comparing frail to robust and prefrail to robust were 3.85 (95% confidence interval [CI] 3.36-4.42) and 1.82 (95% CI 1.58-2.10). Similarly, the corresponding ORs for severe disability were 4.35 (95% CI 3.55-5.34) and 1.78 (95% CI 1.43-2.21). In the age-stratified analysis, in mild disability, the pre-old group (aged 65-74) with frail showed a higher association than the old group (aged ≥ 75) with frail. In severe disability, the old group with frail showed a higher association than the pre-old group with frail. CONCLUSION: The results showed that both prefrail and frail were associated with the incidence of mild and severe disability, and there were different patterns of association between the pre-old/old age groups.

Frailty and all-cause and cause-specific mortality in Japan. International journal

Rumi Matsuo, Naomi Matsumoto, Toshiharu Mitsuhashi, Soshi Takao, Takashi Yorifuji

Archives of gerontology and geriatrics 107 104906 - 104906 2022.12

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: In aging societies, there is an increasing focus on the concept of frailty. However, there is no consistent means to assess this concept. We assessed frailty using the Kihon Checklist (KCL), which is widely used in Japan, and examined the association between frailty and all-cause and cause-specific mortality in Japan, the most aged society in the world. METHODS: This was a retrospective cohort study, and we analyzed 43,312 participants aged ≥ 65 years who were enrolled in basic health checkups in Okayama City, Japan. We defined the frailty status of the participants using the KCL. To assess the association of frailty status with all-cause and cause-specific mortality, we used cause-specific Cox proportional hazard models to estimate hazard ratios (HRs), adjusting for individual potential confounders. Mean follow-up time was 9.3 years. RESULTS: The fully adjusted HR for all-cause mortality was 1.34 (95% confidence interval [CI]: 1.27-1.41) for the prefrail group and 2.22 (95% CI: 2.11-2.33) for the frail group. A similar pattern was observed for cardiovascular disease, respiratory disease, and cancer mortality. Younger people (65-74 years) and women tended to have higher effect estimates than older people (≥ 75 years) and men. CONCLUSION: Prefrailty and frailty can increase the risk of both all-cause and cause-specific mortality. Our study suggests that to support frail patients, it could be effective to focus on the prevention and management of cardiovascular and respiratory disease, and that the KCL may be useful as a method of screening for frailty.

Introduction: It is recommended that users of complementary and alternative medicine (CAM) also seek conventional medical care to prevent the loss of access to appropriate medical care. However, the status of such use is unknown. The aim of this study was to examine the time trends in the proportion of CAM users who also receive conventional medical care for the same symptoms. Methods: This is a repeated cross-sectional study. Of data for 753,978 respondents to the Comprehensive Survey of Living Conditions, which was conducted seven times between 1995 and 2013, data from 17,707 individuals who used acupuncture, moxibustion, anma-massage-shiatsu, or judo therapy were analyzed. Cross-classified multilevel logistic regression models with individuals as level 1 and survey year and cohort as level 2 were used to calculate odds ratios (ORs) and 95% credible intervals (CIs) for combined use of CAM and conventional medical care. Age was entered as an individual-level variable. The period effect after 2003 was entered as a survey year-level variable because the number of eligible persons providing CAM treatments has increased since 2003. Results: Among the 17,707 CAM users, 11,567 (65.3%) were women. When age was entered as an explanatory variable, the results showed that both older men and women tended to receive conventional medical care (women, OR: 1.04, 95% CI: 1.03-1.04; men, OR: 1.03, 95% CI: 1.02-1.04). Additional examination of the possible period effect after 2003 showed a positive (although nonsignificant) association (women, OR: 1.36, 95% CI: 0.89-1.99; men, OR: 1.37, 95% CI: 0.94-1.91). Conclusions: As patient age increased, patients combined CAM use with conventional medicine. The findings also suggested that the combined use of CAM and conventional medicine has increased since 2003.
