Objective: Despite the suspected link between carpal tunnel syndrome (CTS)—a common neuropathy—and psychiatric issues, long-term evidence, especially in Asia, remains scarce. This study investigated the long-term incidence of depression, anxiety, somatoform, and sleep disorders after CTS diagnosis in a South Korean nationwide cohort. Methods: Using the Korean National Health Insurance Service cohort (2002–2013), newly diagnosed CTS patients (2004–2013) were identified following a 2-year washout period. Each CTS patient was propensity score-matched 1:10 with non-CTS controls based on demographics and health status. Cox proportional hazards regression yielded adjusted hazard ratios (aHRs) for incident depressive, anxiety, somatoform, and sleep disorders over up to 10 years of follow-up. Results: Compared to controls, CTS patients had significantly elevated risks for all outcomes: depressive disorders (aHR, 1.59; 95% confidence interval [CI], 1.45–1.74), anxiety disorders (aHR, 1.41; 95% CI, 1.31–1.52), somatoform disorders (aHR, 1.38; 95% CI, 1.23–1.55), and sleep disorders (aHR, 1.36; 95% CI, 1.25–1.49). Risk was notably higher in individuals aged <60 years for all disorders. Males showed higher risks for depression, anxiety, and sleep disorders, while females had a slightly higher risk for somatoform disorders. Conclusion This comprehensive, longitudinal study indicated that CTS is associated with an increased long-term risk of psychiatric disorders. The findings emphasize comprehensive management strategies that integrate mental health screening and interventions tailored to age and sex among patients with CTS.

Objective: AT-rich interactive domain 1A (ARID1A) plays an important role as a tumor suppressor gene in ovarian clear cell carcinoma (OCCC), but the clinical application of ARID1A remains unclear. The aim of this study was to analyze clinicopathological parameters, molecular interactions and immune-infiltration in patients with low ARID1A expression and to provide candidate target drugs. Methods: We investigated the clinicopathologic parameters, specific gene sets/genes, and immunological relevance according to ARID1A expression in 998 OCCC patients from 12 eligible studies (using meta-analyses); 30 OCCC patients from the Hanyang University Guri Hospital (HYGH) cohort; and 52 OCCC patients from gene set enrichment (GSE) 65986 (25 patients), 63885 (9 patients), and 54809 (6 patients and 12 healthy people) of the Gene Expression Omnibus (GEO). We analyzed network-based pathways based on gene set enrichment analysis (GSEA) and performed in vitro drug screening. Results: Low ARID1A expression was associated with poor survival in OCCC from the metaanalysis, HYGH cohort and GEO data. In GSEA, low ARID1A expression was related to the tumor invasion process as well as a low immune-infiltration. In silico cytometry showed that CD8 T cells were decreased with low ARID1A expression. In pathway analysis, ARID1A was associated with angiogenic endothelial cell signaling. In vitro drug screening revealed that cabozantinib and bicalutamide effectively inhibited specific hub genes, such as vascular endothelial growth factor-A and androgen receptor, in OCCC cells with low ARID1A expression. Conclusions Therapeutic strategies making use of low ARID1A could contribute to better clinical management/research for patients with OCCC.

PURPOSE: We aimed to investigate the appropriateness of transport of children via emergency medical service providers (EMSP) according to the decision-maker on referred hospitals (EMSP [EMSP group] vs. guardians [user group]). METHODS: We analyzed first aid records by EMSP for children aged 15 years or younger in Gyeonggi province, Korea, from January 2012 through December 2013. We obtained the following data: scene, symptom, type (high-level [regional/local emergency medical centers] or not) and location (out-of-province or not) of referred hospitals, injury, level of consciousness (alert or not), and prehospital triage results by EMSP (emergent/less emergent or not). RESULTS: A total of 50,407 children were included, of whom 37,626 (74.6%) belonged to the user group. Overall, the most common scene, symptom, and type and location of referred hospitals were home (57.0%), pain (33.3%), and inside-theprovince and local emergency medical centers (44.2%), respectively. The user group showed less frequent injury (P < 0.001), decreased level of consciousness (P < 0.001), and no significant difference in the triage results (P = 0.074). This group showed more frequent transport to high-level and out-of-province emergency medical centers (P < 0.001), and longer transport (P < 0.001). CONCLUSION: The user group showed more frequent transport to high-level or remote referred hospitals without more critical prehospital triage results. Guardian-directed transport of children might be associated with the inappropriate transport of children via EMSP.

PURPOSE: This study aimed to evaluate the clinical significance of Ki-67 and p53 expressions in patients with pancreatic head cancer. METHODS: Between May 2008 and April 2013, immunohistochemical staining for Ki-67 and p53 was performed in 34 patients with pancreatic head cancer (ductal adenocarcinoma). All 34 patients underwent pancreaticoduodenectomy at Chonnam National University Hwasun Hospital, Hwasun, Korea. Clinical and histopathological characteristics were analyzed, relative to p53 expression. RESULTS: Thirty (88.2%) and twenty-one (61.7%) of the 34 pancreatic head cancers exhibited positive expression of Ki-67 and p53, respectively. Patients expressing Ki-67 and p53 experienced more frequent tumor recurrences within 1 year after surgical resection (P = 0.003 and P = 0.030, respectively). However, no correlation was detected between Ki-67 and p53 expression. Ki-67 expression was correlated with pathological grade, lymph node metasatsis, and clinical stage (P < 0.05). Importantly, Ki-67 was the independent predictive factor for postoperative recurrence within 1 year in both univariable and multivariable analyses (odds ratio, 27.219; 95% confidence interval, 1.403-528.135; P = 0.029). CONCLUSION: The expression of Ki-67 and p53 are significantly related to early postoperative recurrence within 1 year after surgical resection in pancreatic head cancer. Especially, Ki-67 was the independent predictive factor for postoperative recurrence within 1 year. Therefore, immunohistochemical staining for Ki-67 and p53 may be applied as a predictive marker for early postoperative recurrence in pancreatic head cancer.

PURPOSE: This study was done to identify whether pre-conditioning exercise has neuroprotective effects against cerebral ischemia, through enhance brain microvascular integrity. METHODS: Adult male Sprague-Dawley rats were randomly divided into four groups: 1) Normal (n=10); 2) Exercise (n=10); 3) Middle cerebral artery occlusion (MCAo), n=10); 4) Exercise+MCAo (n=10). Both exercise groups ran on a treadmill at a speed of 15 m/min, 30 min/day for 4 weeks, then, MCAo was performed for 90 min. Brain infarction was measured by Nissl staining. Examination of the remaining neuronal cell after MCAo, and microvascular protein expression on the motor cortex, showed the expression of Neuronal Nuclei (NeuN), Vascular endothelial growth factor (VEGF) & laminin. RESULTS: After 48 hr of MCAo, the infarct volume was significantly reduced in the Ex+MCAo group (15.6+/-2.7%) compared to the MCAo group (44.9+/-3.8%) (p<.05), and many neuronal cells were detected in the Ex+MCAo group (70.8+/-3.9%) compared to the MCAo group (43.4+/-5.1%) (p<.05). The immunoreactivity of laminin, as a marker of microvessels and Vascular endothelial growth factor (VEGF) were intensively increased in the Ex+MCAo group compared to the MCAo group. CONCLUSION: These findings suggest that the neuroprotective effects of exercise pre-conditioning reduce ischemic brain injury through strengthening the microvascular integrity after cerebral ischemia.
