Purpose: In 2024, the South Korean government proposed an essential medical care package, including the expansion of medical college admissions, which faced strong opposition from the medical community. Consequently, residents resigned, increasing the workload of the remaining staff and putting public health at risk. This study analyzed changes in the hospitalization patterns of trauma patients during this political conflict period using single-center data from the National Health Insurance Service Ilsan Hospital. Methods: Data from the entire year 2023 and from March to August 2024 were used for analysis, excluding January and February 2024 when the conflict escalated. The selection criteria included patients with trauma who visited the emergency room, and comparisons were made between the periods before and during the medical conflict. Results: In 2023, the total number of patients with trauma were 1,182 (an average of 98.5 per month). From March to August 2024, the number dropped to 204 (34.2 per month), reflecting a significant reduction in the monthly average number of patients with trauma. Despite the overall decline, the number of severe trauma cases remained relatively stable, indicating a shift toward more critical patient care. Emergency department length of stay decreased significantly from 295 min in 2023 to 187 min in 2024. Conclusion The ongoing strain on emergency and support department risks leads to an irreversible collapse if critical points are reached. To address this, localized trauma centers are needed to relieve the burden on larger medical institutions and improve the efficiency of trauma care systems during crises.

and Relevance: Severe necrosis and mild fibrosis were observed in the liver and forelimb skeletal muscles. Based on histological analysis, we diagnosed iron overload myopathy by secondary hemochromatosis. Secondary hemochromatosis with severe muscle atrophy and myositis is very rare, and this is the first report of iron-overload myopathy in a dog.

Background: Intravenous (IV) fluid therapy is essential and widely used; however, it is associated with high error rates, largely due to human factors, necessitating constant and careful monitoring by medical staff. Gravity-based systems are prone to errors, whereas electronic pumps, though more accurate, are limited by size, cost, and complexity. In this study, the impact of single-drop weight measurement and real-time light source monitoring on the accuracy of gravity-based infusion systems was evaluated. Methods: Gravity-based IV sets with IV infusion flow regulators (IIFRs) from three manufacturers were tested using 1,000 ml of 0.9% saline. The drops per min and the drop weight were recorded using a pulse oximeter, which served as a light source. The flow rates from the pulse oximeter group (PO) were compared with those from the manufacturer’s drop volume (C) and the IIFR groups. The mean absolute percentage error (MAPE) of predicted versus actual volumes was analyzed along with correlations between the residual volume and drop rate. Results: The PO group values were statistically closer to those of the actual measurements than the C and IIFR groups values (P < 0.05), demonstrating higher accuracy and lower MAPE, except at 300 ml/h when than those of the C group, independent of residual volume. The residual volume strongly correlated with the drop rate (r > 0.9). Conclusions Real-time drop measurements using light sources combined with single-drop weight assessment improve the accuracy of these systems. Integrating pulse oximeters into IV sets may enhance clinical precision and reduce provider workload.

This research group (forensic research via omics markers in environmental health vulnerable areas: FROM) aimed to develop biomarkers for exposure to environmental hazards and diseases, assess environmental diseases, and apply and verify these biomarkers in environmentally vulnerable areas. Environmentally vulnerable areas—including refineries, abandoned metal mines, coal-fired power plants, waste incinerators, cement factories, and areas with high exposure to particulate matter—along with control areas, were selected for epidemiological investigations. A total of 1,157 adults, who had resided in these areas for over 10 years, were recruited between June 2021 and September 2023. Personal characteristics of the study participants were gathered through a survey. Biological samples, specifically blood and urine, were collected during the field investigations, separated under refrigerated conditions, and then transported to the laboratory for biomarker analysis. Analyses of heavy metals, environmental hazards, and adducts were conducted on these blood and urine samples. Additionally, omics analyses of epigenomes, proteomes, and metabolomes were performed using the blood samples. The biomarkers identified in this study will be utilized to assess the risk of environmental disease occurrence and to evaluate the impact on the health of residents in environmentally vulnerable areas, following the validation of diagnostic accuracy for these diseases.

Fournier’s gangrene is infectious, necrotizing, life-threatening fasciitis of the perineal, genital, and perianal regions leading to soft-tissue necrosis and sepsis, and is treated with aggressive surgical debridement and antimicrobial agents. Negative-pressure wound therapy can be used if septic risk is controlled. An 82-year-old woman presented with Fournier’s gangrene and septic shock. After emergency debridement, perineal resection, a colostomy, and daily wound debridement was performed under general anesthesia (1 week). Multiple intubations and extubations under general anesthesia are a risk factor for poor patient outcomes. Therefore, negative-pressure wound therapy was performed under light sedation using noninvasive ventilation in the intensive care unit after extubation and for wound debridement. One month later, the perineum was reconstructed. Procedures performed under light sedation should be considered for patients requiring periodic invasive surgical procedures who are burdened by repeated general anesthesia. The number of general anesthesia sessions was significantly reduced by using noninvasive ventilation.
