RESUMEN
Purpose@#Management options for extraperitoneal bladder injury (EBI) associated with pelvic fracture are variable. Predictive factors of operative management (OM) in patients with EBI associated pelvic fracture have not been previously addressed. This study assessed the current epidemiology of blunt traumatic urinary bladder injury and evaluated relevant clinical findings of patients with EBI associated with pelvic fracture who received OM. @*Methods@#Patients with urinary bladder injury with or without pelvic fracture from blunt trauma from January 1, 2014 to December 31, 2019 were identified from the institute trauma registry (n = 12,891). Demographics, mechanism of injury, type of urinary bladder injury, pelvic fracture configuration, and management options were analysed in the study population (n = 9,894). @*Results@#Of the 1,400 patients who had pelvic and/or acetabular fracture, 32 (2.3%) had urinary bladder injury. Of the 8,494 patients without pelvic and/or acetabular fracture, 12 (0.1%) had nonpelvic fracture urinary bladder injury. The total incidence of urinary bladder injuries in the study population was 0.4% (44/9,894). Patients with EBI associated with pelvic fracture who underwent OM, had a higher frequency of high-grade pelvic injury (100% vs 0%, p = 0.015), concomitant pelvic surgery (75.0% vs 0%, p = 0.001), and non-lateral compression type pelvic fracture (62.5% vs 10.0%, p = 0.043) compared with patients who underwent non-operative management of EBI. @*Conclusions@#These data suggest that OM may be considered especially in patients with EBI associated with pelvic fracture with high grade pelvic injury, concomitant pelvic surgery, and nonlateral compression type pelvic fracture.
RESUMEN
An African swine fever (ASF) outbreak in wild boars was first reported on October 2, 2019, in South Korea. Since then, additional cases were reported in South Korea's border areas. We here report the identification of ASF virus (ASFV) DNAs from two out of eight environmental abiotic matter samples collected from areas where ASF-positive wild boar carcasses were found. Comparative genomic investigations suggested that the contaminating ASFV DNAs originated from the wild boar whose carcass had been found near the positive sample sites.This is the first report on the identification of ASF viral material in wild boar habitats.
RESUMEN
Purpose@#We aimed to assess the clinical efficacy of transcatheter arterial embolization (TAE) for treating hemothorax caused by chest trauma. @*Materials and Methods@#Between 2015 and 2019, 68 patients (56 male; mean age, 58.2 years) were transferred to our interventional unit for selective TAE to treat thoracic bleeding. We retrospectively investigated their demographics, angiographic findings, embolization techniques, technical and clinical success rates, and complications. @*Results@#Bleeding occurred mostly from the intercostal arteries (50%) and the internal mammary arteries (29.5%). Except one patient, TAE achieved technical success, defined as the immediate cessation of bleeding, in all the other patients. Four patients successfully underwent repeated TAE for delayed bleeding or increasing hematoma after the initial TAE. The clinical success rate, defined as no need for thoracotomy for hemostasis after TAE, was 92.6%. Five patients underwent post-embolization thoracotomy for hemostasis. No patient developed major TAE-related complications, such as cerebral infarction or quadriplegia. @*Conclusion@#TAE is a safe, effective and minimally invasive method for controlling thoracic wall and intrathoracic systemic arterial hemorrhage after thoracic trauma. TAE may be considered for patients with hemothorax without other concomitant injuries which require emergency sur-gery, or those who undergoing emergency TAE for abdominal or pelvic hemostasis.
RESUMEN
Objective@#Blunt thoracic aortic injury (BTAI) is a rare but fatal injury. BTAI has been treated surgically, but thoracic endovascular aortic repair (TEVAR) is used as a treatment option and has shown good results. The purpose of this study was to analyze the outcomes of patients with BTAI treated using TEVAR. @*Methods@#BTAI patients who had received TEVAR for five years were analyzed. We investigated injury severity score, aortic injury site, computed tomography findings and mortality. @*Results@#We identified 17 patients, and all were diagnosed using computed tomography. Twelve patients received TEVAR as an emergency, and the remaining five patients received TEVAR delayed. The most common injury site was isthmus (82%), and the median injury severity score was 33. There were 15 cases with a BTAI grade of 3 and two cases with a BTAI grade of 4. The mortality rate was 11.8% (n=2). @*Conclusion@#TEVAR is more meaningful because it is easier and faster and has fewer complications than thoracotomy in patients with traumatic aortic injury.

RESUMEN
Non-alcoholic fatty liver disease (NAFLD) has the potential to develop into hepatic steatosis and progress to terminal liver diseases such as cirrhosis and hepatocellular carcinoma. This human clinical study was aimed to demonstrate that SPB-201 (powdered-water extract of Artemisia annua) can improve liver function in subjects with non-alcoholic liver dysfunction at mild to moderate levels. A decrease of 271% in aspartate aminotransferase (AST) level and a significant decrease of 334% in alanine aminotransferase (ALT) level was observed in the test group as compared to the control group at the 4 weeks follow-up. In addition, after 8 weeks, decreases of 199% in AST level and 216% in ALT level were reported in the test group as compared to the control group. These results confirmed that SPB-201 intake significantly enhanced liver function and health. Moreover, the Multidimensional Fatigue Scale score of the test group decreased but that of the control group increased, implicating that SPB-201 also eliminated overall fatigue. No significant adverse events were observed among all subjects during the study. Taken together, our clinical study confirmed the excellent efficacy and safety of SPB-201 in liver function improvement, showing the possibility of SPB-201 as a functional food to restore liver dysfunction and treat liver diseases.
RESUMEN
Background@#We report our 10-year experience with traumatic peripheral arterial injury repair at an urban level I trauma center. @*Methods@#Between January 2007 and December 2016, 28 adult trauma patients presented with traumatic peripheral arterial injuries. Data were retrospectively collected on demographic characteristics, the mechanism of injury, the type of vascular injury, and physiological status on initial assessment. The analysis also included the Mangled Extremity Severity Score (MESS), Injury Severity Score, surgical procedures, and outcome variables including limb salvage, hospital stay, intensive care unit stay, and postoperative vascular complications. @*Results@#Four (14.3%) patients required amputation due to failed revascularization. MESS significantly differed between patients with blunt and penetrating trauma (8.2±2.2 vs.5.8±1.3, respectively; p=0.005). The amputation rate was not significantly different between patients with blunt and penetrating trauma (20% vs. 0%, respectively; p=0.295). The overall mortality rate was 3.6% (1 patient). @*Conclusion@#Blunt trauma was associated with higher MESS than penetrating trauma, and amputation was more frequent. In particular, patients with blunt trauma had significantly higher MESS than patients with penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005), and amputation was performed when revascularization failed in cases of blunt trauma of the lower extremity. Therefore, particular care is needed in making treatment decisions for patients with peripheral arterial injuries caused by blunt trauma.
RESUMEN
Background@#Korea set up a new diagnosis-related group as a demonstration project in 2009. The new diagnosis-related group was reformed in 2016. The main purpose of the study is to identify the effect of reform on coverage of national health insurance. @*Methods@#This study collected inpatient data from a hospital that contains medical information and cost from 2015 July to 2016 June. The dependent variable was the coverage of national health insurance. The dependent variable was divided by total, internal medicine partition, surgical partition, and psychiatric partition. To analyze the effect of the reform, this study conducted an interrupted time series analysis. The final sample included 23,695. @*Results@#The health insurance coverage of internal medicine has the highest, followed by surgery and psychiatry. The health insurance coverage of bundle payment is higher than that of unbundled payment. The proportion of bundled payment and non-benefit decreased and the proportion of unbundled payment increased. The coverage of national health insurance significantly increased after policy reform in internal medicine partition (p-value=0.0356). @*Conclusion@#The results of the study imply that policy reform enhanced the coverage of national health insurance in internal medicine. The government needs to monitor side effects such as an increase of unbundled payment.

RESUMEN
Acquired hemophilia A (AHA) is a rare disease where typically coagulation factor VIII is inhibited by autoantibodies. It occurs in patients with no personal or familial history of bleeding. In this case study a 61-year-old male presented with a huge psoas hematoma. He had no history of bleeding disorders. He was initially diagnosed with delayed traumatic hematoma. Despite conservative and surgical treatments, coagulopathy was not resolved and postoperative bleeding continued. Consequently, coagulation factor tests were performed and showed reduced activity of factor VIII (2.7%). In addition, factor VIII inhibitor was detected. The patient was diagnosed with AHA and administered recombinant factor VIII for 3 days which resulted in the cessation of bleeding. AHA can lead to a life-threatening hemorrhage, and needs to be considered in differential diagnoses in any patients presenting with unexplained and repeated bleeding, where there is no personal or familial history of bleeding disorders.

A 55-year-old man was admitted to the trauma center after a car accident. Cardiac tamponade, traumatic aortic injury, and hemoperitoneum were diagnosed by ultrasonography. The trauma surgeon, cardiac surgeon, and interventional radiologist discussed the prioritization of interventions. Multi-detector computed tomography was carried out first to determine the severity and extent of the injuries, followed by exploratory sternotomy to repair a left auricle rupture. A damage control laparotomy was then performed to control mesenteric bleeding. Lastly, a descending thoracic aorta injury was treated by endovascular stenting. These procedures were performed in the hybrid-angio room. The patient was discharged on postoperative day 135, without complications.

RESUMEN
Betula platyphylla var. japonica (Betulaceae), also known as Asian white birch, is an endemic medicinal tree, the bark of which has been used in Chinese traditional medicine for the treatment of various inflammatory diseases. In our continuing search for bioactive compounds from Korean natural resources, a phytochemical investigation of the bark of B. platyphylla var. japonica led to the isolation of 7-oxo-β-sitosterol (1) and soyacerebroside I (2) from its ethanol extract as main components by liquid chromatography (LC)/mass spectrometry (MS)-based analysis. The structures of isolates were identified by comparison of ¹H and ¹³C nuclear magnetic resonance spectroscopic data and physical data with the previously reported values and LC/MS analyses. To the best of our knowledge, this is the first study to demonstrate that the isolated compounds, 7-oxo-β-sitosterol and soyacerebroside I, were isolated in B. platyphylla var. japonica. We examined the effects of the isolates on the regulation of adipocytes and osteoblast differentiation. These isolates (1 and 2) produced fewer lipid droplets compared to the untreated negative control in Oil Red O staining of the mouse mesenchymal stem cell line without altering the amount of alkaline phosphatase staining. The results demonstrated that both compounds showed marginal inhibitory effects on adipocyte differentiation but did not affect osteoblast differentiation.

The concept of acute care surgery (ACS) incorporates trauma, surgical critical care, and emergency general surgery. It was designed in the early 2000s by the United States as a solution to the looming crisis of trauma care and non-trauma emergency surgery. Reduced surgical opportunities for trauma surgeons resulted in a decreased interest in trauma surgery. Surgical sub-specialization further accelerated an indifference towards trauma and emergency general surgery. Started in 2008, the trauma center project in Korea is still in its infancy. Although the need for ACS was presented since the inception of the trauma center project, there was a lack of implementation at trauma centers due to government regulations. However, ACS has been initiated at several non-trauma center hospitals and is mainly operated by surgical intensivists. Studies demonstrate that adding emergency surgery to a trauma service does not compromise the care of the injured patients, despite an increase in trauma volume. Positive impacts of ACS are reported by numerous researches. We believe that the development and advancement of trauma centers will necessitate a discussion for the implementation of the ACS model at trauma centers in Korea.

Most of aortic injuries after blunt chest trauma usually occur at the aortic isthmus and are identified in the emergency department soon after arrival. Delayed aortic injures by fractured posterior ribs, however, are relatively rare and have been reported only a few times. We recently experienced an iatrogenic descending aortic injury sustained as a result of a direct puncture by a sharp rib end after surgical stabilization of rib fractures.
RESUMEN
An ischemia-reperfusion injury of the intestine due to blunt trauma is very rare. Low blood flow can result in an incarceration and an ischemia-reperfusion injury of the small intestine. A 63-year-old woman fell, producing a splenic rupture. Despite the successful angio-embolization of the splenic rupture, the patient continued to suffer from hypotension. During laparotomy to identify the bowel injury, no intestinal perforation was found. However, we found a hemorrhagic infarction of the small intestine with congestion of the submucosal blood vessels. The part of bowel with the hemorrhagic infarction was resected and reconstructed with a jejuno-colic anastomosis. After surgery, she recovered from the trauma and was discharged without complications. We present this ischemia-reperfusion injury of the intestine due to blunt trauma. Meticulous examination and computed tomography scan is mandatory for diagnosis and assessment of treatment outcome.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.
