Abstract

Background/Objectives: Internet use positively impacts mental health in older adults, with health literacy (HL) playing a key role. While social networks may complement individual HL, the role of neighborhood relationships in this association, particularly by gender, remains unclear. This study examined how the association between HL and Internet use among older adults was modified by neighborhood relationships. Methods: Using baseline data from the Chofu–Digital–Choju project, a cross-sectional analysis was conducted on 1955 community-dwelling adults aged 65–84 (889 men and 1066 women). HL was assessed using the Communicative and Critical Health Literacy scale and dichotomized at four points. Neighborhood relationships were categorized as high (visiting/chatting with neighbors) or low (exchanging greetings/no relationship). Gender-stratified logistic regression analyses were performed with Internet use as the dependent variable, with HL, neighborhood relationships, and their interaction as independent variables. Results: Internet user proportion was 55.6% for men and 41.8% for women. HL was positively associated with Internet use in both genders, though patterns differed. Among men, the HL–Internet use association was consistent (OR = 3.09; 95% CI: 2.25–4.24) regardless of neighborhood relationship levels. For women, this association was significantly modified (interaction OR = 0.46, 95% CI: 0.24–0.87). Women with low HL but strong neighborhood relationships showed increased odds of Internet use (OR = 2.08, 95% CI: 1.32–3.26). Conclusions: Gender-specific patterns in HL and neighborhood relationships influence Internet use among older adults. Neighborhood relationships may compensate for low HL in women, underscoring the need for gender-sensitive strategies to promote digital HL. [ABSTRACT FROM AUTHOR]

Abstract

Background/Objective: Frailty is a growing public health challenge in Japan's rapidly aging population, where 28.8% are aged ≥ 65. While multicomponent interventions have shown potential in preventing frailty, traditional face-to-face programs face accessibility challenges. This study evaluated the feasibility and short-term changes of an online multicomponent intervention on frailty-related factors among community-dwelling older adults. Methods: In this single-arm feasibility study, 132 participants (mean age 75.7; standard deviation 4.8 years, 65.2% women) completed a six-week online intervention combining exercise, nutrition education, cognitive activities, and the Coimagination Method to foster social connections, meeting weekly for 75 min sessions in groups of up to 10 participants. Results: The intervention demonstrated feasibility with a 96.4% retention rate and a 94.0% average participation rate. While no significant changes were observed in physical activity levels, autonomic nervous system indicators, or cognitive function, carotenoid scores and hemoglobin concentration improved significantly, with more pronounced improvements among women than men. Conclusions: This study demonstrates the high feasibility of online multicomponent interventions for older adults and suggests potential benefits for nutritional status markers, particularly among women. These findings indicate a promising and accessible approach to frailty prevention, though randomized controlled trials with longer intervention periods and direct frailty assessments are required to establish effectiveness conclusively.

Abstract

Introduction: This study explored employment trends among working‐age patients undergoing hemodialysis using 5‐year surveys from 1996 to 2021. Policy changes affecting individuals with disabilities, the economic environment, and employment status among the general population in Japan were considered. Differences in trends by gender and health status were examined. Methods: Employment status was categorized into employment and nonemployment; and regular, nonregular, and self. Analytical data with similar characteristics were generated over the six surveys using the propensity score method. Results: The employment rate, especially among women, increased from 1996 to 2021. However, the employment rate ratio to the general population was approximately 80% for men and 50% for women, even in 2021. The employment rate increased with an expansion in nonregular employment. Women's employment trends could be explained by changes in real gross domestic product and employment quotas for individuals with disabilities. Conclusion: Employment trends differ by gender and by regular versus nonregular employment. [ABSTRACT FROM AUTHOR]

42. Effectiveness of real-time PCR for diagnosis and prognosis of varicella-zoster virus keratitis

Abstract

Pupose: To determine the efficacy of real-time PCR for the diagnosis and prognosis of varicella-zoster virus (VZV) keratitis. Study design: Retrospective case series. Methods: Patients: 545 consecutive patients with keratitis were examined to quantify copy numbers of VZV DNA by real-time PCR. Association of copy numbers of DNA of VZV to clinical signs and disease course was assessed using logistic regression analysis and Cox proportional hazard model. Results: Of the 545 eyes, 38 eyes (6.9%) were diagnosed as VZV keratitis. The copy numbers of the DNA of VZV (median: 104.19 copy) was significantly associated with diagnosis of VZV keratitis with the highest odds ratio (OR) of 3390 (for median copy) compared to clinical signs. Diagnostic accuracy of the VZV DNA copy indicated good diagnostic value of area under the curve (0.92) by receiver operating characteristic analysis, and detection of unrelated VZV DNA from the cornea was very rare (0.2%). When the VZV DNA copy and clinical signs were assessed for association with the disease course after herpes zoster ophthalmicus, the disease duration was significantly prolonged in VZV keratitis cases with higher numbers of VZV DNA copies, iritis, and history of recurrences. The amount of VZV DNA led to a continuous risk to prolong disease duration until the ocular inflammation subsides (hazard ratio (HR) 0.17, 95%CI: 0.07 - 0.42, for median copies). Conclusions: Higher VZV DNA copy numbers are associated with the refractoriness of VZV keratitis, and its evaluation may be a clinically useful way to diagnose and manage VZV keratitis., source:Japanese Journal of Ophthalmology. 2018, 62(4), 425-431 This is a post-peer-review, pre-copyedit version of an article published in Japanese Journal of Ophthalmology.

This study was limited to financial strains over the life course before initiating hemodialysis to eliminate the influence of financial strains resulting from resignation from paid jobs. We examined which of the four life course models—pathway, latent, social mobility, and accumulation—were appropriate to describe the influences of financial strains over the life course on older patients’ health.Patients and Methods: Data were obtained from a cross-sectional survey of 6,644 outpatients in dialysis facilities across Japan. We selected participants aged 60 years and older at the time of the survey. Numbers of dialysis complications, activities of daily living (ADL) disability, and depressive symptoms were selected as health outcomes. Benchmark periods over the life course were constructed in three parts: less than 18 years (childhood), 18– 35 years (young adults), and 35– 50 years (middle-aged). We retrospectively measured financial strains over the life course.Results: Pathway models best described the influence of financial strains over the life course
