RESUMEN
BACKGROUND: With rapidly aging populations in most parts of the world, it is only natural that the need for caregivers for older adults is going to increase in the near future. Therefore, most technologically proficient countries are in the process of using artificial intelligence (AI) to build socially assistive robots (SAR) to play the role of caregivers in enhancing interaction and social participation among older adults. OBJECTIVE: This study aimed to examine the effect of intervention through AI SAR on the cognitive function of older adults through a systematic literature review. METHODS: We conducted a meta-analysis of the various existing studies on the effect of AI SAR on the cognitive function of older adults to standardize the results and clarify the effect of each method and indicator. Cochrane collaboration and the systematic literature review flow of PRISMA (Preferred Reporting Item Systematic Reviews and Meta-Analyses) were used on original, peer-reviewed studies published from January 2010 to March 2022. The search words were derived by combining keywords including Population, Intervention, and Outcome-according to the Population, Intervention, Comparison, Outcome, Time, Setting, and Study Design principle-for the question "What is the effect of AI SAR on the cognitive function of older adults in comparison with a control group?" (Population: adults aged ≥65 years; Intervention: AI SAR; Comparison: comparison group; Outcome: popular function; and Study Design: prospective study). For any study, if one condition among subjects, intervention, comparison, or study design was different from those indicated, the study was excluded from the literature review. RESULTS: In total, 9 studies were selected (6 randomized controlled trials and 3 quasi-experimental design studies) for the meta-analysis. Publication bias was examined using the contour-enhanced funnel plot method to confirm the reliability and validity of the 9 studies. The meta-analysis revealed that the average effect size of AI SAR was shown to be Hedges g=0.43 (95% CI -0.04 to 0.90), indicating that AI SAR are effective in reducing the Mini Mental State Examination scale, which reflects cognitive function. CONCLUSIONS: The 9 studies that were analyzed used SAR in the form of animals, robots, and humans. Among them, AI SAR in anthropomorphic form were able to improve cognitive function more effectively. The development and expansion of AI SAR programs to various functions including health notification, play therapy, counseling service, conversation, and dementia prevention programs are expected to improve the quality of care for older adults and prevent the overload of caregivers. AI SAR can be considered a representative, digital, and social prescription program and a nonpharmacological intervention program that communicates with older adults 24 hours a day. Despite its effectiveness, ethical issues, the digital literacy needs of older adults, social awareness and reliability, and technological advancement pose challenges in implementing AI SAR. Future research should include bigger sample sizes, pre-post studies, as well as studies using an older adult control group.

RESUMEN
BACKGROUND: Older adults-classified as a high-risk group-are highly likely to experience increased loneliness due to the implementation of various policies designed to prevent the spread of COVID-19. Accordingly, this study aims to examine the effects of a pilot social prescribing project for elderly people in rural area of South Korea during the COVID-19 pandemic. METHODS: Using the PRECEDE-PROCEED model, the effectiveness of the pilot project was verified through pre- and post-impact and outcome evaluation. RESULTS: According to the results of the impact evaluation, loneliness reduced significantly, while the social participation attitude score increased. Although the average score of self-efficacy increased, it was not statistically significant. Moreover, it was found that self-esteem increased significantly. In the outcome evaluation, depression reduced considerably. CONCLUSION: To conclude, the pilot social prescribing project was effective in reducing depression and loneliness for the elderly in rural areas of Korea. It was also confirmed that there is potential to develop a new health promotion project that can improve the self-esteem of the elderly, and expand their social activities. Second, the pilot project was carried out in an integrated manner by utilizing resources in communities with good accessibility. Therefore, it is expected to be used as a new "Integrated community care model" to improve the mental health of the elderly in rural areas. Third, during the COVID-19 pandemic, the elderly tend to experience increasing feelings of depression, isolation, and loneliness due to "social distancing." Therefore, it is expected that social prescribing programs for the elderly in rural areas would become a new alternative for relieve mental disorder of the seniors.
RESUMEN
Background: Trichloroacetic acid (TCA) is an agent widely applied in dermatology for skin regeneration. To test whether TCA can offer an advantage for the regeneration of oral soft tissue defects, the cellular events following TCA application were explored in vitro and its influence on the oral soft tissue wound healing was evaluated in a canine palate model. Methods: The cytotoxicity and growth factor gene expression in human gingival fibroblasts were tested in vitro following the application of TCA at four concentrations (0.005%, 0.05%, 0.5% and 1%) with different time intervals (0, 3, 9 and 21 h). One concentration of TCA was selected to screen the genes differentially expressed using DNA microarray and the associated pathways were explored. TCA was injected in open wound defects of the palatal mucosa from beagle dogs (n = 3) to monitor their healing and regeneration up to day 16-post-administration. Results: While the 0.5-1% concentration induced the cytoxicity, a significantly higher expression of growth factor genes was observed after 3 and 9 h following the 0.5% TCA application in comparison to other groups. DNA microarray analysis in 0.5% TCA group showed 417 genes with a significant 1.5-fold differential expression, involving pathways of cell cycle, FoxO signaling, p53 signaling, ubiquitin mediated proteolysis and cAMP signaling. In vivo results showed a faster reepithelialization of TCA-treated wounds as compared to spontaneous healing. Conclusion: TCA promoted the healing and regeneration of oral soft tissue wound defects by up-regulating the cell cycle progression, cell growth, and cell viability, particularly at a concentration of 0.5%.
