Background: Serum calcium and magnesium levels are a key factor of the coagulation cascade and may potentially contribute to the pathophysiology of intracerebral hemorrhage (ICH) expansion. The aim of this study was to attain and sustain target levels of serum calcium and magnesium for three days following admission. Methods: A single-blind, prospective, multicenter randomized study was conducted from 2019 to 2022 years, enrolling acute ICH patients aged 18–80 years, with radiological diagnosis and without surgical intervention. Participants were randomly assigned in a 1:1 ratio to either the study group or the control group. In the study group, the target serum levels of calcium (9–10.2 mg/dL) and magnesium (2–3 mg/dL) were actively achieved and maintained for a duration of 3 days following admission. The primary outcome was the expansion of ICH volume within the first 3 days between the study group and the control groups. Results: After implementing inclusion/exclusion criteria, 105 of 354 patients remained in the study. There were no significant differences in ICH volume on hospital days 2 and 3 between the groups. Admission factors including Glasgow coma scale score, hemoglobin level, ICH volume, and spot sign showed significant correlations in multivariate analysis. On the third day of hospitalization, admission serum magnesium levels showed a significant correlation with ICH expansion, whereas calcium levels did not. Conclusion Admission serum magnesium levels were found to correlate with hematoma expansion in patients with acute ICH. While magnesium itself may not be a direct therapeutic target, it could serve as a valuable indicator for identifying potential therapeutic strategies aimed at preventing ICH volume increase.

Background: Though accumulating evidence suggests an association between childhood trauma and anhedonia, further analysis is needed to consider specific traumatic dimensions, both traits and state anhedonia, and the role of circulating proteins. Therefore, this study investigated the association between different types of childhood traumas and their influence on anhedonia-related symptoms, and to evaluate the influence of anhedonia traits and plasma proteins as mediators. Methods: This study included 170 patients with schizophrenia, bipolar disorder, major depressive disorder, and healthy controls aged 19–65 years. Multiple reaction monitoring was performed to quantify plasma proteins, and 464 proteins were analyzed. The association between childhood trauma dimensions, anhedonic traits, and related symptoms was analyzed with linear regression. A series of mediation analyses was performed to determine whether anhedonic traits and plasma proteins mediated the association between childhood trauma and anhedonia-related symptoms. Results: Childhood emotional neglect was significantly associated with anhedonic traits and anhedonia-related symptoms. Mediation analysis revealed that the indirect effect of anhedonic traits for childhood emotional neglect on anhedonia-related symptoms (effect = 0.037; bias-corrected CI, 0.009 to 0.070) was statistically significant. The indirect effect of plasma TNR5 for anhedonic traits on anhedonia-related symptoms was statistically significant (effect = −0.011; bias-corrected CI, −0.026 to −0.002). Serial mediation analysis revealed that the indirect effect of childhood emotional neglect on anhedonia-related symptoms via anhedonic traits and TNR5 was statistically significant (effect = 0.007; biascorrected CI, 0.001 to 0.017). Conclusion Anhedonic traits and plasma TNR5 protein levels serially mediated the association between childhood emotional neglect and anhedonia-related symptoms.The study highlights the importance of considering both psychopathological traits and biological correlates when investigating the association between childhood trauma and psychopathological symptoms.

Purpose: Persimmon (Diospyros kaki Thunb.) is rich in phytochemicals (e.g., tannin and beta-carotene.), vitamins (e.g., vitamins A and C), minerals (e.g., calcium and potassium), and dietary fiber. Persimmon exhibits efficacy against diseases such as cancer, hypertension, and heart disease. This study examined the antioxidant and immune-enhancing activities of Fuyu (a sweet persimmon) and Hachiya (an astringent persimmon) and evaluated their potential as functional food ingredients. Methods: The antioxidant and immune-enhancing activities of Fuyu and Hachiya persimmons were evaluated by extracting them with hot water and ethanol (100%). The antioxidant activity was assessed by measuring the total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), and oxygen radical absorbance capacity (ORAC). Six-year domestic red ginseng was used as a reference for assessing the immune-enhancing activity. Nitric oxide (NO) production, phagocytosis, cytokine levels interleukin [IL]-2, IL-4, IL-10, and interferon-γ), and inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expression were analyzed. Results: The hot water extracts of Fuyu and Hachiya persimmon exhibited significantly higher TPC, TFC, DPPH RSA, and ORAC levels than the ethanol extract. The Hachiya persimmon extract generally showed comparable or higher immune-enhancing activity than the Fuyu persimmon extract in NO production, cytokine activity, phagocytosis, and expression of iNOS and COX-2 genes. Conclusion Hachiya persimmon possesses superior antioxidant properties to Fuyu persimmon while exhibiting comparable immune-enhancing activity. These characteristics highlight its potential for beneficial applications. Nevertheless, further research is required to elucidate these effects and optimize their use in health-promoting interventions.

Purpose: We report the diagnosis and conservative treatment of a patient with dacryocystitis accompanied by a congenital lacrimal sac diverticulum.Case summary: An 11-year-old boy presented with itching and redness in his right eye. His best-corrected visual acuity was 0.8 in the right eye and 1.2 in the left. Physical examination revealed redness, swelling, and tenderness around the right lacrimal sac area. Probing of the nasolacrimal duct showed no obstruction. Additional tests were performed under the diagnosis of acute dacryocystitis. Computed tomography and magnetic resonance imaging suggested inflammation of the soft tissue with abscess formation around the right orbit, with inflammation extending to the lower eyelid. After 7 days of inpatient treatment, the symptoms improved. Dacryocystography performed after the symptoms improved showed a small amount of residual contrast in a space near the lacrimal sac, leading to the diagnosis of a right lacrimal sac diverticulum. Conclusions In patients with dacryocystitis without nasolacrimal duct obstruction, congenital lacrimal diverticulum should be suspected.

Objective: The Daegu region experienced the first wave of the pandemic at the beginning of the coronavirus disease 2019 (COVID-19) outbreak in Korea. Other non-COVID-19-related treatments during a community outbreak, such as cardiovascular diseases, were expected to impact emergency departments. In acute myocardial infarctions, time is an important factor affecting the patient outcome. This study examined how community COVID-19 outbreak affected STsegment elevated myocardial infarction (STEMI) care in emergency departments. Methods: A retrospective analysis was performed on patients visiting five emergency departments in the Daegu area who were diagnosed with STEMI from February 18 to April 17 each year from 2018 to 2020. The demographic characteristics, prehospital variables, in-hospital time variables, and treatment results were collected. The cases were divided into the pre-COVID period and the COVID period for comparison. Results: The study included 254 patients (194 pre-COVID, 60 during COVID). The symptom-to-door time did not differ. Although the door-to-first doctor time was shortened (4 min vs. 2 min, P=0.01), the rate of coronary angiogram along with the door-to-angiogram time and the door-to-balloon time did not change. The length of stay in the emergency department was delayed during COVID-19 (median, 136 min vs. 404 min; P<0.01). The in-hospital length of stay and mortality were similar in both groups. Conclusion The time to treat STEMI was not delayed significantly during the first wave of the COVID-19 outbreak in the Daegu area compared with the pre-pandemic period. Mortality did not change. The length of stay was elongated significantly in the emergency department but not in the hospital.

Background: Decreased acetabular version and posterior acetabular coverage of the femoral head have been regarded as the leading causes of sport-related posterior hip dislocation or subluxation. This study aimed to examine the posterior acetabular coverage of the femoral head in 21 patients who sustained posterior hip dislocation or subluxation during sport activities. Methods: The anterior and posterior acetabular rims on 3-dimensional computed tomography (3D-CT) images were delineated on the normal side in these patients. Radiologic signs, including crossover and posterior wall signs, were examined. The fracture center level (FCL) of the posterior acetabular wall was identified on axial CT images of the injured hip and the level was marked on the normal side. The difference in the femoral head coverage by posterior and anterior acetabular rims was measured by measuring the horizontal distance between anterior and posterior acetabular rims at the FCL (posterior-anterior [P-A] index). The acetabular version was measured at the femoral head and FCL using axial CT images of the normal side. Femoral head coverage by the posterior acetabular wall on the normal side was measured using 3D-CT (areal coverage). Results: The crossover and posterior wall signs were positive in 14 and 10 patients, respectively, in 3D-CT images. The FCL was evenly distributed in the proximal half of the posterior acetabular wall. Seven patients had a P-A index of ≤ 0, and all were positive for the crossover sign. The anterior acetabular rim was relatively prominent in these patients. The acetabular version was lower at the FCL than at the femoral head center (p < 0.001). The proximal half areal coverage of the posterior acetabular wall was significantly smaller than the whole areal coverage (p = 0.003). Conclusions Superior–posterior coverage of the femoral head by the posterior acetabular wall was insufficient in patients who sustained hip posterior dislocation or subluxation during sports activities.

Background: Sclerostin, initially recognized for its pivotal role in bone metabolism, has gained attention for its multifaceted impact on overall human health. However, its influence on frailty—a condition that best reflects biological age—has not been thoroughly investigated. Methods: We collected blood samples from 244 older adults who underwent comprehensive geriatric assessments. Sclerostin levels were quantified using an enzyme-linked immunosorbent assay. Frailty was assessed using two validated approaches: the phenotypic model by Fried and the deficit accumulation frailty index (FI) by Rockwood. Results: After controlling for sex, age, and body mass index, we found that serum sclerostin levels were significantly elevated in frail individuals compared to their robust counterparts (P<0.001). There was a positive correlation between serum sclerostin concentrations and the FI (P<0.001). Each standard deviation increase in serum sclerostin was associated with an odds ratio of 1.87 for frailty (P=0.003). Moreover, participants in the highest quartile of sclerostin levels had a significantly higher FI and a 9.91-fold increased odds of frailty compared to those in the lowest quartile (P=0.003 and P=0.039, respectively). Conclusion These findings, which for the first time explore the association between circulating sclerostin levels and frailty, have significant clinical implications, positioning sclerostin as one of potential blood-based biomarkers for frailty that captures the comprehensive physical, mental, and social aspects of the elderly, extending beyond its traditional role in bone metabolism.
