Objective: This study investigated how educational levels modify the relationship between the standard deviation of NN intervals (SDNN) of heart rate variability and the development of post-traumatic stress disorder (PTSD). Methods: Participants with physical injuries were enrolled from a trauma center and monitored over two years. Initial assessments included SDNN and educational attainment, along with socio-demographic and clinical variables. PTSD diagnoses were made at 3, 6, 12, and 24 months post-injury using the Clinician-Administered PTSD Scale for DSM-5.Logistic regression analyses were conducted. Results: Of the 538 participants, 58 (10.8%) developed PTSD during the follow-up period. A significant interaction effect was observed: lower SDNN was significantly linked to PTSD in individuals with higher education, but not in those with lower education. Conclusion The study identified education-dependent associations between SDNN and PTSD development, emphasizing the importance of tailored PTSD prevention strategies that consider both SDNN and educational levels.

Purpose: To investigate the epidemiological trends and socioeconomic disparities associated with ankylosing spondylitis (AS) in South Korea over a decade (2010–2021) using National Health Insurance Service (NHIS) claims data. Materials and Methods: Employing data from the NHIS database, this study identified 31753 incident AS patients in 2010–2021.We calculated the annual age-standardized prevalence and incidence rates and analyzed crude incidence rates and diagnostic patterns across age groups. Additionally, we compared the mean annual proportions of medical aid recipients between AS patients and the general population, utilizing p for trend analysis to assess the differences between the two groups across increasing age groups. Results: The study period saw a steady increase in age-standardized prevalence (from 34.6 to 91.0 per 100000) and incidence rates (from 4.41 to 8.33 per 100000 person-years), with the most substantial rise of incidence found in younger demographics. Diagnostic trends revealed a shift from internal medicine (IM) to other specialties including orthopedics with increasing patient age groups (p for trend=0.008), indicating old-age diagnosis in non-IM departments. A 1.4-fold higher proportion of medical aid recipients in AS patients (p<0.001) and the widening gap of dependency on medical aid in older age groups (p for trend=0.012) compared to the general population highlight socioeconomic disparities. Conclusion This comprehensive analysis reveals the growing epidemiological burden of AS, especially in younger populations, and the socioeconomic disparities regarding the disease in South Korea. It underscores the need for early diagnosis and effective treatment strategies, paving the way for health interventions and policies aimed at improving patient outcomes and addressing socioeconomic disparities.

Background: In patients with metastatic renal cell carcinoma (mRCC), sites of metastatic involvement have been reported to be associated with a difference in survival. However, the frequency and survival according to different sites of metastases in Korean patients with mRCC remain unclear. Therefore, this study aimed to assess the frequency of metastatic site involvement and the association between sites of metastatic involvement and survival in Korean patients with mRCC. Methods: This retrospective study used the multicenter cohort of the Korean Renal Cancer Study Group mRCC database to identify patients who started targeted therapy between December 2005 and March 2018. Data on the frequency of metastatic organ involvement at the time of mRCC diagnosis and oncologic outcomes according to different sites of metastasis were analyzed. Results: A total of 1,761 patients were eligible for analysis. Of the 1,761 patients, 1,564 (88.8%) had clear cell RCC, and 1,040 (59.1%) had synchronous metastasis. The median number of metastasis sites was 2 (interquartile range [IQR], 1–6). The median age at the initiation of systemic therapy was 60 years (IQR, 29–88), 1,380 (78.4%) were men, and 1,341 (76.1%) underwent nephrectomy. Based on the International Metastatic Renal Cell Carcinoma Database Consortium model, patients were stratified into favorable-, intermediate-, and poor-risk groups with 359 (20.4%), 1,092 (62.0%), and 310 (17.6%) patients, respectively. The lung (70.9%), lymph nodes (37.9%), bone (30.7%), liver (12.7%), adrenal gland (9.8%), and brain (8.2%) were the most common sites of metastasis, followed by the pancreas, pleura, peritoneum, spleen, thyroid, and bowel. Among the most common sites of metastasis (> 5%), the median cancer-specific survival (CSS) ranged from 13.9 (liver) to 29.1 months (lung). An association was observed between liver, bone, and pleural metastases and the shortest median CSS (< 19 months). Conclusion In Korean patients with mRCC, metastases to the lung, lymph nodes, bone, liver, adrenal gland, and brain were more frequent than those to other organs. Metastases to the liver, bone, and pleura were associated with poor CSS. The findings of this study may be valuable for patient counseling and guiding future study designs.
