Background: As the roles of chemotherapy (Chemo) and radiation therapy (Radio) in the definitive treatment of breast cancer have expanded, a broader understanding of the factors associated with breast cancer-related lymphedema (BCRL) has become increasingly essential. Therefore, we investigated the association between multimodality treatment and the risk of BCRL. Methods: In this retrospective study conducted using National Health Insurance data and the Korea National Cancer Incidence Database (2006–2017), 114,638 participants who underwent Surgery (Surg) or Chemo within 6 months after breast cancer diagnosis were enrolled, and the effect of multimodality treatment on the risk of BCRL was analyzed using the Cox proportional-hazards model. Multimodality treatment administered through six months of treatment was grouped as only Surg; Surg/Chemo; Surg/ Chemo/Radio; Surg/Radio; only Chemo; and Chemo/Radio. Results: The risk of BCRL was higher in the Surg/Chemo group (hazard ratio [HR]: 1.54, 95% confidence interval [CI]: 1.43–1.65), Surg/Chemo/Radio group (HR: 1.51, 95% CI: 1.43–1.65), only Chemo group (HR: 1.58, 95% CI: 1.45–1.71), and Chemo/Radio group (HR: 1.13, 95% CI: 1.00–1.29) in comparison with the only Surg group. Conclusion: BCRL occurrence is an after-effect of complex breast cancer treatments, and the risk may vary depending on the treatment method, including Surg, chemo, and radio. Our findings suggest that multidisciplinary strategies are required to minimize the risk of BCRL development in patients with breast cancer. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to evaluate the clinical applicability of a customised power wheelchair joystick using rapid prototyping with 3D modeling and printing technology within a rehabilitation centre for patients with cervical spinal cord injury. Materials and Methods: Two male participants with tetraplegia following cervical-level spinal cord injury who had difficulty operating a powered wheelchair were recruited. The procedure of the joystick-making and training service consists of four steps: (1) driving evaluation; (2) digital fabrication; (3) functional test; and (4) driving training. K-QUEST 2.0 (Korean-Quebec User Evaluation of Satisfaction version 2.0) was used to measure the usability of the off-the-shelf and customised joystick. Results: During the application process, several redesign stages were required to obtain the final customised joystick. After participants attended a 30-min driving training five times per week for 8 weeks, the usability of the customised joystick was higher than that of the off-the-shelf one. Conclusion: Providing the customised joystick-making and training service can be used in hospitalised rehabilitation centre before the hospital discharge of patients and returns to their everyday lives. IMPLICATIONS FOR REHABILITATION: 3D printing technology in rehabilitation clinics can provide new benefits, including cost-effectiveness, customisation of assistive devices, higher productivity, and enhanced collaboration with clients. More specifically, the entire intervention process, from medical evaluation, designing and manufacturing the devices, and training the client, can be performed efficiently and quickly by rehabilitation practitioners who best understand the client's characteristics. This study aimed to confirm the clinical applicability of a quick and efficient service for a customised power wheelchair joystick using 3D modelling and printing technology in rehabilitation centres for patients with cervical spinal cord injury. This study is expected to provide clinical support for connecting potential users and practitioners with technological advancements. [ABSTRACT FROM AUTHOR]

Background Global population aging, and the accelerated increase in the number of oldest-old adults, over 80 years, has implied a heightened need for long-term care (LTC). We aimed to provide a theoretical care cascade of LTC services to assess publicly funded LTC (Analysis 1) and to investigate the association between the use of LTC insurance (LTCI) and unmet care needs among older people (Analysis 2) in South Korea. Methods Analysis 1 used data from the eighth wave (2020) of the Korean Longitudinal Study of Aging (KLoSA), the 2020 National Health Insurance Service LTCI Statistical YearBook and the 2020 National Awareness Survey of LTCI. The care cascade consisted of the target population, service contacts, coverage and outcomes. Analysis 2 used the fifth to eighth waves of KLoSA, and LTCI analysis was based on three groups: not aware, aware but do not use and aware and use. Unmet care needs were defined as the absence of help among older people with care needs. Results Among 8,489,208 people aged 65 or older in 2020, 1,368,148 (16.1%) were estimated to want care. Of these, 62.7% (N  = 857,984) had LTCI service contact and 807,067 (94.1%) of those had used LTCI services in the past year (Analysis 1). Older people who were aware and used LTCI were less likely to report unmet activities of daily living (ADL) (prevalence ratio (PR): 0.34, 95% confidence interval (CI): 0.18–0.66) or unmet instrumental ADL (IADL) needs (PR: 0.27, 95% CI: 0.17–0.43) than those who were not aware (Analysis 2). Conclusions This article provides a theoretical cascade to assess LTC provision in South Korea and a preliminary model for other countries. Korea's LTCI is associated with reduced unmet ADL and IADL needs. [ABSTRACT FROM AUTHOR]
