1.Expanding the health belief model on dementia knowledge, fear, and preventive behaviors among older adults in Korea: a cross-sectional descriptive study
Journal of Korean Biological Nursing Science 2025;27(1):60-71
This study aimed to expand the health belief model by incorporating dementia knowledge and fear and to assess the effects of these variables on dementia prevention behaviors among older adults. Methods: In total, 199 elderly individuals from 10 senior centers in Korea completed a structured questionnaire assessing characteristics, dementia knowledge, fear, health beliefs, and prevention behaviors. Measures included the Alzheimer’s Disease Knowledge Scale, the Korean version of the Fear of Alzheimer’s Disease Scale, and the Korean version of the Motivation to Change Lifestyle and Health Behavior for Dementia. Hierarchical polynomial regression was conducted to examine the impact of integrating dementia knowledge and fear into the health belief model. Results: Hierarchical polynomial regression across four models revealed significant effects of various factors on dementia prevention behaviors, explaining 12%–36% of the variance. Perceived barriers significantly decreased dementia prevention behaviors, while higher levels of self-efficacy and cues to action had a positive influence. Additionally, a nonlinear relationship was identified between dementia knowledge and prevention behaviors, with the positive impacts of increased knowledge potentially diminishing beyond a certain point. Conclusion: Our findings underscore the necessity of modifying the health belief model to integrate dementia knowledge and fear, which play critical roles in shaping preventive behaviors among older adults. Future investigations should examine the optimal level of dementia knowledge to promote these behaviors and elucidate the intricate relationship between knowledge and actions.

Purpose:
This study investigated hand-washing practice among community-dwelling older adults during the coronavirus disease 2019 (COVID-19) pandemic and aimed to identify the impact of COVID-19-related concerns and depression on hand-washing practice.
Methods:
This was a secondary analysis of data extracted from the 2020 Community Health Survey. The primary data were collected through self-reporting from August 10 to September 8, 2020 in a cross-sectional study. The subjects consisted of 1,350 adults aged 65 or older living in J Province who participated in the 2020 Community Health Survey. Results: The factors affecting hand-washing practice among older adults were male gender (β = –.18, p < .001), age (β = –.07, p = .001), no education (β = –.20, p < .001) and elementary, middle, and high school graduation (β = –.15, p < .001) compared to a college or higher education, poor health perception (β = –.13, p < .001), COVID-19-related concerns (β = .08, p = .005), and depression (β = –.07, p = .001). To summarize, the factors negatively affecting hand-washing practice included male gender, lower education level, poor health perception, and depression, while the factors positively associated with hand-washing practice included COVID-19-related concerns.
Conclusion
These findings show the importance of considering these multifaceted determinants when designing targeted interventions and educational programs aimed at promoting hand-washing among older adults. Additionally, based on the relationship between hand-washing practice and COVID-19-related concerns and depression, interventions that can alleviate mental problems along with providing proper education are required.

Objective:
This study aimed to assess the outcomes of outpatient day-care management of unruptured intracranial aneurysm (UIA), and to present the risks associated with different management strategies by comparing the outcomes and adverse events between outpatient day-care management and management with longer admission periods.
Materials and Methods:
This retrospective cohort study used prospectively registered data and was approved by a local institutional review board. We enrolled 956 UIAs from 811 consecutive patients (mean age ± standard deviation, 57 ± 10.7 years; male:female = 247:564) from 2017 to 2020. We compared the outcomes after embolization among the different admission-length groups (1, 2, and ≥ 3 days). The outcomes included pre- and post-modified Rankin Scale (mRS) scores and rates of adverse events, cure, recurrence, and reprocedure. Events were defined as any cerebrovascular problems, including minor and major stroke, death, or hemorrhage.
Results:
The mean admission period was 2 days, and 175 patients (191 aneurysms), 551 patients (664 aneurysms), and 85 patients (101 aneurysms) were discharged on the day of the procedure, day 2, and day 3 or later, respectively. During the mean 17-month follow-up period (range 6–53 months; 2757 patient years), no change in post-mRS was observed compared to pre-mRS in 99.6% of patients. Cure was achieved in 95.6% patients; minimal recurrence that did not require re-procedure occurred in 3.5% patients, and re-procedure was required in 2.3% (22 of 956) patients due to progressive enlargement of the recurrent sac during follow up (mean 17 months, range, 6–53 months). There were eight adverse events (0.8%), including five cerebrovascular (two major stroke, two minor strokes and one transient ischemic stroke), and three non-cerebrovascular events. Statistical comparison between groups with different admission lengths (1, 2, and ≥ 3 days) revealed no difference in the outcomes.
Conclusion
This study revealed no difference in outcomes and adverse events according to the admission period, and suggested that UIA could be managed by outpatient day-care embolization.

Background:
Post-transplantation cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG) are common pro‑ phylactic strategies for graft-versus-host disease (GVHD) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Interleukin (IL)-6 is a surrogate marker for cytokine release syndrome (CRS) and acute GVHD.Method The clinical outcomes and complications of haplo-HSCT with PTCy plus ATG versus PTCy monotherapy were compared according to serum IL-6 levels at Chungnam National University Hospital (Daejeon, South Korea) from Jan‑ uary 2019 to February 2023.
Results:
Forty patients who underwent haplo-HSCT were analyzed. A significant difference in IL-6 levels was observed between the PTCy plus ATG and PTCy alone groups (7.47 ± 10.55 vs. 117.65 ± 127.67; p = 0.003). More patients in the PTCy plus ATG group had a CRS grade of 0 than in the PTCy alone group (p < 0.001). Serum IL-6 levels were associated with grades II–IV acute GVHD (r = 0.547, p < 0.001). The cumulative incidence (CI) of grades II–IV acute GVHD was significantly higher in the PTCy alone group (67.9% vs. 4.8%; p < 0.001). No significant difference in the CI for chronic GVHD was detected between the PTCy plus ATG and PTCy alone groups (72.1% vs. 82.0%; p = 0.730). The CI of 1-year non-relapse mortality was significantly higher in the PTCy alone group than in the PTCy plus ATG group (42.2% vs. 15.9%; p = 0.022). The 1-year overall survival (OS) was significantly better in the PTCy plus ATG group (75.9% vs. 35.3%; p = 0.011). The 1-year GVHD-free, relapse-free survival rate was 29.4% in the PTCy alone group and 54.0% in the PTCy plus ATG group (p = 0.038).
Conclusion
Serum IL-6 levels were higher in the PTCy alone group than in the PTCy plus ATG group. The addition of ATG before stem cell infusion affected IL-6 levels and reduced the incidences of CRS and grade II–IV acute GVHD in haplo-HSCT patients. This study suggests that PTCy plus ATG as GVHD prophylaxis in haplo-HSCT is beneficial in terms of clinical outcomes and complications of HSCT.
