Objective: Multiple cohort studies have investigated the potential link between anesthesia and dementia. However, mixed findings necessitate closer examination. This study aimed to investigate the association between anesthesia exposure and the incidence of dementia, considering different anesthesia types and anesthetic agents. Methods: This nationwide cohort study utilized data from the South Korean Health Insurance Review and Assessment Service database, covering 62,541 participants, to investigate the correlation between anesthesia exposure and dementia incidence. Results: Results revealed an increased risk of dementia in individuals who underwent general (hazard ratio [HR], 1.318;95% confidence interval [CI], 1.061−1.637) or regional/local anesthesia (HR, 2.097; 95% CI, 1.887−2.329) compared to those who did not. However, combined general and regional/local anesthesia did not significantly increase dementia risk (HR, 1.097; 95% CI, 0.937−1.284). Notably, individual anesthetic agents exhibited varying risks; desflurane and midazolam showed increased risks, whereas propofol showed no significant difference. Conclusion This study provides unique insights into the nuanced relationship between anesthesia, individual anesthetic agents, and the incidence of dementia. While confirming a general association between anesthesia exposure and dementia risk, this study also emphasizes the importance of considering specific agents. These findings under-score the need for careful evaluation and long-term cognitive monitoring after anesthesia.

Objective: Prior research has emphasized psychological resilience as a potential protective factor against alcohol use disorder in diverse populations, with limited exploration of its relationship in the general population. This study investigated the association between the lifetime and one-year prevalence of alcohol use disorder and resilience. Methods: Data obtained from the National Mental Health Survey of Korea 2021 (5,511 participants; 40.7% response rate) encompassed information on alcohol use disorders, resilience, experiences of psychological trauma, and major mental disorders. The analyses compared demographics, psychological trauma, resilience, and the prevalence of major mental disorders based on alcoholism. The contribution of resilience to alcoholism was assessed utilizing Rao-Scott logistic regression, with adjustments made for confounding variables. Results: Individuals with both lifetime and 1-year alcohol use disorder and dependence exhibited significantly lower levels of resilience on the Connor-Davidson Resilience Scale. Diminished resilience predicted morbidity and persisted even after adjusting for depressive and anxiety disorders, psychological trauma, nicotine use disorders, age, gender, education, income, marital status, and occupation. Conclusion Diminished resilience is a prognostic indicator of increased likelihood of both lifetime and current alcoholism in the general population.

Streptococcus pneumoniae is a common cause of bacterial respiratory infections, and invasive pneumococcal disease (IPD) is associated with high morbidity and mortality rates. Pneumococcal vaccines are effective to prevent pneumococcal infections, and new vaccines have recently been developed to enhance their preventive potency. New vaccines have been designed to protect against a broad range of pneumococcal serotypes and to elevate their efficacy against traditionally targeted serotypes. In 2021, the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention updated its recommendations for pneumococcal vaccination, advising the use of new vaccines, 20-valent pneumococcal conjugate vaccine (PCV20) or PCV15, instead of PCV13. In Korea, PCV15 was introduced in 2024, along with guidelines recommending the administration of both PCV15 and 23-valent pneumococcal polysaccharide vaccine at least one year apart. However, as PCV20 is expected to be introduced soon in Korea, a pneumococcal vaccination strategy must be established with guidance for overseas cases.Pneumococcal vaccination strategies for adults should be individualized based on age and underlying diseases. In addition, the impact of newly introduced vaccines should be considered. Furthermore, adaptive changes in IPD because of increased vaccination rates and antibiotic resistance should be carefully observed, and efforts should be made to develop vaccines that can effectively protect against dangerous serotypes.

Objective: This study aimed to examine the psychiatric impact of the Seoul Halloween crowd crush on individuals related to the victims compared to the general population. It also explores the moderating effect of resilience on the relationship between trauma exposure and psychiatric symptoms. Methods: In total, 2,220 participants completed various post-incident questionnaires (Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Hwa-byung symptom scale, post-traumatic stress disorder checklist for DSM-5, and Brief Resilience Scale) 30 days after the incident. Moderation analyses were conducted using the PROCESS macro in the statistical package for the social sciences. Results: Individuals related to the victims exhibited higher symptom severity and a greater risk for clinically significant levels of depression, anxiety, anger, and post-traumatic stress disorder (PTSD) (odds ratio=3.28, 3.33, 1.51, and 4.39 respectively). The impact of relevance to victims on anxiety and PTSD symptoms was moderated by resilience, with a stronger effect observed for individuals with low resilience (β=3.51, 95% confidence interval [CI] 2.78–4.24 for anxiety and β=14.53, 95% CI 12.43–16.63 for PTSD) than for those with high resilience (β=1.69, 95% CI 0.72–2.65 for anxiety and β=8.33, 95% CI 5.56–11.09 for PTSD). Conclusion When related to the victims, it was found that not only PTSD, but also depression, anxiety, and anger could intensify. Resilience emerged as a potential buffer against these adverse effects, emphasizing its significance in mitigating the psychiatric impact of community trauma.
