Purpose: This developmental study explored the conceptual feasibility and applicability of a metaverse-based clinical assessment platform as a complementary tool to conventional objective structured clinical examinations in undergraduate medical education. Methods: A targeted literature review and expert consensus process were conducted to identify domains of clinical competence in which metaverse technologies could provide added value. Based on these findings, prototype virtual patient simulations were developed within a metaverse environment. Large language models (LLMs) were integrated to support dynamic, interactive history-taking simulations, and pilot modules for physical examination were also created. Results: Integration of LLMs into virtual patient scenarios enabled realistic, context-sensitive medical interviews, facilitating interactive dialogue between examinees and simulated patients. In contrast, physical examination modules faced technical limitations, particularly in replicating procedures requiring tactile or haptic feedback, such as palpation and percussion. Nevertheless, the metaverse environment enabled delivery of consistent and reproducible scenarios, supporting objective assessment of communication and diagnostic reasoning skills. Conclusion Metaverse-based simulations augmented by LLMs offer a promising approach to scalable and standardized clinical assessment, particularly within cognitive and interpersonal competency domains. Although current technological constraints limit the fidelity of physical examination simulations, rapid advancements in immersive and haptic technologies may help overcome these barriers in the near future. Further research is needed to evaluate the educational efficacy, validity, and feasibility of deploying such platforms in summative, high-stakes assessment contexts.

Electroconvulsive therapy (ECT) is performed under general anesthesia, and the choice of anesthetic induction agents critically influences multiple aspects of the treatment, including the seizure quality, cardiovascular stability, and post-procedural recovery. Developing anesthetic strategies that reliably achieve loss of consciousness while preserving adequate seizure expression has been a central challenge in ECT practice because most commonly used induction agents possess anticonvulsant properties. Dexmedetomidine (DEX), recently introduced primarily for sedation in intensive care and various procedural settings, is a selective α2-adrenergic receptor agonist that has minimal impacts on the seizure threshold and seizure duration while providing a complex profile of sedation, analgesia, anxiolysis, and sympatholysis. These properties help reduce the acute increases in blood pressure and heart rate induced by electrical stimulation, and DEX also offers advantages for airway management because it induces virtually no respiratory depression.Importantly, DEX has also been consistently reported to reduce pre-procedural anxiety and postictal agitation or aggression, suggesting that it may allow more stable management throughout the entire ECT course compared with conventional anesthetic agents. This review examines the pharmacological characteristics and clinical implications of DEX in anesthetic induction for ECT and discusses its potential roles in future clinical practice.

Objectives: Hospitalization is an important procedure for alleviating the symptoms of patients with mental illness. However, in many countries, the trend of deinstitutionalization began a long time ago, and under the influence of CRPD and WHO QualityRights, perceptions of hospitalization are changing. In this context, it is important to identify the psychosocial characteristics related to the recovery of patients in psychiatric hospitalization in Korea. Therefore, this study sought to identify factors that influence recovery attitudes among inpatient. Through this, we attempted to summarize what is needed for the successful application of QualityRights in the future. Methods: For 82 inpatients at A Mental Hospital in Korea, we analyzed demographic characteristics, number of hospitalizations, types of hospitalization, social support, stigma, and attitude toward recovery, human rights sensitivity by assessing self report questionnaires. We analyzed the data through regression and ANOVA. Results: As a result of regression analysis, social support and human rights sensitivity was found to have a significant impact on attitudes toward recovery. Additionally, as a result of ANOVA, there was a significant difference in stigma depending on the number of hospitalizations, and no significant differences were found in other psychosocial variables . And There were no significant differences in psychosocial variables according to hospitalization type. Conclusion Social support and human rights sensitivity were found to influence attitudes toward recovery. Additionally, individuals with longer hospitalizations were found to experience more internalized stigma compared to individuals with relatively shorter hospitalizations. Through this, implications for domestic application of WHO QualityRights were summarized and limitations were discussed.

Objectives: The social and economic costs of severe mental illness, including psychosis, are increasing, and methods to reduce costs such as a mobile app-based approach have been tried more than ever. This study aims to explore and analyze the methods that have been used in previous studies for mobile app-based psychosocial interventions for personal and clinical recovery of psychosis. Methods: To identify mobile apps associated with psychosis, psychotic disorder, and other related terms, we searched for literature published from 2017 to 2023 (n=21). After classifying them into personal and clinical recovery, we qualitatively analyzed each study’s topics, objectives, measurement tools, results, and other aspects. Results: For personal recovery, the focus was mainly on improving daily living, self-management, and cognitive and social function improvement, and for clinical recovery, the focus was mainly on preventing symptom recurrence and managing symptoms. Mobile apps for improving daily living functions, cognitive functions, and relapse prevention have significant effects. While mobile apps for improving social function and symptom management mainly reported smaller effects. Conclusion The results of this study suggest that mobile app-based psychosocial interventions for personal and clinical recovery of psychosis are likely to be utilized. Finally, the significance and limitations of the studies were discussed.

Scrub typhus, a mite-borne infectious disease, is caused by Orientia tsutsugamushi. Despite many attempts to develop a protective strategy, an effective preventive vaccine has not been developed. The identification of appropriate Ags that cover diverse antigenic strains and provide long-lasting immunity is a fundamental challenge in the development of a scrub typhus vaccine. We investigated whether this limitation could be overcome by harnessing the nanoparticle-forming polysorbitol transporter (PST) for an O. tsutsugamushi vaccine strategy.Two target proteins, 56-kDa type-specific Ag (TSA56) and surface cell Ag A (ScaA) were used as vaccine candidates. PST formed stable nano-size complexes with TSA56 (TSA56-PST) and ScaA (ScaA-PST); neither exhibited cytotoxicity. The formation of Ag-specific IgG2a, IgG2b, and IgA in mice was enhanced by intranasal vaccination with TSA56-PST or ScaA-PST. The vaccines containing PST induced Ag-specific proliferation of CD8 + and CD4 +T cells. Furthermore, the vaccines containing PST improved the mouse survival against O.tsutsugamushi infection. Collectively, the present study indicated that PST could enhance both Ag-specific humoral immunity and T cell response, which are essential to effectively confer protective immunity against O. tsutsugamushi infection. These findings suggest that PST has potential for use in an intranasal vaccination strategy.
