Purpose: : Health literacy, or the ability to find, understand, and use health information, is a key focus in South Korea’s ‘5th National Health Promotion Comprehensive Plan.’ However, despite South Korea’s high internet penetration, research on digital health information use among people with developmental disabilities is limited. This study assesses the current state of digital health literacy in this population. Methods: : A survey was conducted on the people with disabilities and people without disabilities. General digital health information was measured using an 8-item scale by Skinner (2006), and COVID-19-related health information was assessed with a 10-item tool developed by the research team. A total of 365 responses were analyzed, comprising people with physical disabilities (189), developmental disabilities (82), and those without disabilities (94). Data analysis was performed using SPSS version 28, including MANOVA and descriptive statistics. Results: : eHealth scores for individuals with developmental disabilities (24.6 ± 9.8) were significantly lower than those with physical disabilities (32.6 ± 7.9) and those without disabilities (33.9 ± 9.1). Similarly, Covid-eHealth scores were lower for individuals with developmental disabilities (24.6 ± 8.4) compared to those with physical disabilities (29.5 ± 6.8) and those without disabilities (31.3 ± 7.7). The differences in both cases were statistically significant (p < 0.001). Conclusion : This study represents the first comprehensive examination of digital health literacy among people with developmental disabilities in South Korea. The findings indicate that while this group has lower digital health literacy, appropriate education and support can improve their skills. This underscores the need for policies and support systems to ensure they can access and effectively use digital health information, especially as healthcare becomes more digital.

Background and Objectives: Metformin, a commonly used antidiabetic drug, has been reported to exhibit promising anticancer effects across various tumor types. This study investigated the effectiveness of combining metformin with radiotherapy (RT) to treat head and neck squamous cell carcinoma (HNSCC).Materials and Method In vitro experiments were conducted in which FaDu and SCC-25 cells were treated with metformin, followed by irradiation. Cell proliferation was evaluated by MTT assay, and apoptosis was assessed by staining with annexin V-fluorescein isothiocyanate/ propidium iodide, followed by flow cytometry. Western blotting was performed to evaluate changes in apoptotic markers. In vivo experiments were performed using a murine AT-84 allograft model, where tumor volume was measured and serum samples were collected to assess the level of vascular endothelial growth factor (VEGF). Results: The combination of metformin and RT significantly reduced cell proliferation in a dose- and time-dependent manner, and led to a significant increase in the apoptotic rate, accompanied by the upregulation of cleaved caspase-8 and FoxO3, and the downregulation of Bcl-2. The combination treatment also exhibited antiangiogenic effects, as shown by the reduced hypoxia-inducible factor-1 alpha level and inhibited tube formation in the endothelial cells. The combined therapy in the mouse model led to marked decrease in tumor volume and the serum VEGF level in comparison to both the control group and the RT alone. Conclusion The concurrent use of metformin and RT successfully suppressed cell proliferation, triggered apoptosis, and increased the antiangiogenic effects in HNSCC. These results support the use of metformin as an adjunct to RT for the treatment of HNSCC.

Background: Atopic dermatitis (AD) patients usually wonder if their condition will worsen after vaccination or if they should continue with the treatment they are receiving. Considering that many patients treated with dupilumab had previously experienced severe AD symptoms and flares, the concerns are more understandable. Objective: This study aimed to investigate the safety of the coronavirus disease 2019 (COVID-19) vaccination in patients with AD treated with dupilumab. Methods: We enrolled 133 patients (101 dupilumab-treated and 32 systemic oral agentstreated as control group) with AD from six hospitals. Patients were asked about worsening pruritus and AD (5-point Likert scale) after vaccination. AD variables (eczema area and severity index [EASI], investigator’s global assessment [IGA], itch numerical rating scale [NRS], sleep NRS, and patient-oriented eczema measure [POEM]) were compared pre- and postvaccination. Adverse reactions to the COVID-19 vaccination were observed. Results: The incidence of adverse reactions to COVID-19 vaccines and worsening AD symptoms in dupilumab-treated patients were not significantly different compared with that in the control group. The itch NRS score increased significantly after vaccination (p<0.001).However, there were no statistically significant differences between the pre-and post-EASI, IGA, and POEM scores. Eight patients (7.9%) had worse EASI scores and required rescue therapy; however, most were easily managed with low-dose steroids or topical agents. None of the patients discontinued dupilumab treatment. Conclusion No serious adverse reactions were observed in patients with AD after COVID-19 vaccination. Exacerbation of pruritus and AD symptoms was observed but was mostly mild and transient.

Background: Dermatophyte infection is one of the most common skin diseases affecting the skin, hair, and nails. Despite widespread recognition of the disease, missing details and misperceptions are commonplace in the general population. Objective: This study aimed to investigate the public perception and behavior regarding dermatophytosis of the hands and feet. Methods: This results from an online survey conducted between July 2022 and August 2022. The survey included 1,000 Korean participants aged 20 to 69 years, of whom 60% experienced symptoms of tinea pedis or onychomycosis. The questionnaire focused on the awareness and personal experience of tinea pedis and perception of the treatment of dermatophytosis. Results: Of the 1,000 participants, nearly 80% regarded tinea pedis as a common skin condition by which anyone can be affected. Furthermore, 88.4% had heard that the treatment of tinea pedis could be harmful, causing skin rash (60.4%) and worsening liver function (48.5%). Among 896 participants who noticed suspicious symptoms, 81.2% did not visit the clinic because it was not severe (50.1%) and seemed easily manageable (25.7%). Of the respondents, 84.4% preferred to meet dermatologists rather than non-dermatologist doctors regarding skin diseases, mainly because of trust in experts and belief in a faster cure. Conclusion Providing accurate and detailed information via online media, educational campaigns, and medical papers can rectify misconceptions and improve patient appliance, contributing to public skin health.
