Abstract
PURPOSE To evaluate the effectiveness of track embolization using gelatin sponge slurry in percutaneous ultrasound (US)-guided liver biopsy. MATERIALS AND METHODS Among the 543 patients who underwent percutaneous US-guided liver biopsies between September 2018 and August 2021, 338 who did not undergo track embolization and 105 who underwent track embolization were included in the analysis. All procedures were performed with 18-gauge coaxial core biopsy needles. Patients' laboratory data were reviewed. Patients in both groups were subdivided into the following 2 groups: (a) those with targeted biopsy for a focal liver lesion and (b) those with nontargeted biopsy for a liver parenchyma. Moreover, postbiopsy events, such as transfusion and transarterial embolization, were assessed. To minimize selection bias, propensity score matching (PSM) was performed. RESULTS After PSM, all factors that could affect bleeding risk were well-matched and well-balanced between the 2 groups (P > .474). In the non-track embolization group, 17 (16.2%) patients experienced major or minor bleeding-related adverse events (AEs). In contrast, in the track embolization group, only 5 (4.8%) patients experienced major or minor bleeding-related AEs, which was significantly lower than that in the non-track embolization group (P = .007). All 5 (4.8%) cases of major bleeding-related AEs were observed in the non-track embolization group (P = .024). CONCLUSIONS In this study, a retrospective analysis was performed using PSM for percutaneous US-guided liver biopsy. Track embolization using gelatin sponge slurry is significantly superior in the prevention of bleeding-related AEs after US-guided liver biopsy.

Abstract
BACKGROUND Transcatheter arterial embolization (TAE) is an established approach for controlling hemorrhage in adults with acute abdominal and pelvic trauma. However, its application in pediatric trauma is not well established. This study aimed to evaluate the safety and effectiveness of TAE in a population of pediatric patients with blunt trauma. METHODS This retrospective study was conducted in pediatric patients (<18 years) who underwent TAE for blunt trauma between February 2014 and July 2022. The patients were categorized into subgroups based on age and body weight. Patient demographics, injury severity, transfusion requirements, and clinical outcomes were analyzed. RESULTS Exactly 73 patients underwent TAE. Technical success was achieved in all patients (100%), and clinical success was achieved in 83.6%. The mortality and complication rates were 4.1% and 1.4%, respectively. The mean duration of hospitalization was 19.3 days. Subgroup analysis showed that age, body weight, and sex did not significantly affect clinical success. The injury severity score and transfusion requirement were predictors of clinical success, with lower values associated with better outcomes. CONCLUSIONS TAE is effective and safe for managing blunt pediatric trauma in younger and lighter patients. Injury severity and transfusion requirement are predictors of clinical success.

Abstract
OBP-301 is an oncolytic adenovirus modified to replicate within cancer cells and lyse them. This open-label, non-comparative, phase I dose-escalation trial aimed to assess its safety and optimal dosage in 20 patients with advanced hepatocellular carcinoma. Good tolerance was shown with a maximum tolerated dose of 6 × 1012 viral particles. The most common treatment-emergent adverse events were influenza-like illness, pyrexia, fatigue, decreased platelet count, abdominal distension, and anemia. Cohorts 4 and 5 had approximately 50% higher levels of CD8+ T cells in the peripheral blood after injection. The best target response occurred in 14 patients, 4 of whom had progressive disease. Multiple intratumoral injections of OBP-301 were well tolerated in patients with advanced hepatocellular carcinoma. The stable disease rate for the injected tumors was greater than the overall response rate, even with no obvious tumor response. OBP-301 might have a greater impact on local response as histological examination revealed that the presence of OBP-301 was consistent with the necrotic area at the injection site. Increased infiltration of CD8+ T cells and <1% PD-L1 expression were observed in tumors after injection. Improved antitumor efficacy might be achieved in future studies via viral injection with volume adjustment and in combination with other immuno-therapeutics.

Abstract
Trauma is an injury to the body that involves multiple anatomical and pathophysiological changes caused by forces acting from outside the body. The number of patients with trauma is increasing as our society becomes more sophisticated. The importance and demand of traumatology are growing due to the development and spread of treatment and diagnostic technologies. In particular, damage to the large blood vessels of the chest can be life-threatening, and the sequelae are often severe; therefore, diagnostic and therapeutic methods are becoming increasingly important. Trauma to non-aortic vessels of the thorax and aorta results in varying degrees of physical damage depending on the mechanism of the accident and anatomical damage involved. The main damage is hemorrhage from non-aortic vessels of the thorax and aorta, accompanied by hemodynamic instability and coagulation disorders, which can be life-threatening. Immediate diagnosis and rapid therapeutic access can often improve the prognosis. The treatment of trauma can be surgical or interventional, depending on the patient's condition. Among them, interventional procedures are increasingly gaining popularity owing to their convenience, rapidity, and high therapeutic effectiveness, with increasing use in more trauma centers worldwide. Typical interventional procedures for patients with thoracic trauma include embolization for non-aortic injuries and thoracic endovascular aortic repair for aortic injuries. These procedures have many advantages over surgical treatments, such as fewer internal or surgical side effects, and can be performed more quickly than surgical procedures, contributing to improved outcomes for patients with trauma.

Abstract
BACKGROUND There have been few reports comparing image quality and radiation dose of aorta computed tomography angiography (CTA) between the high-pitch and the hybrid technique. PURPOSE To compare the image quality and radiation dose among non-electrocardiogram (ECG)-gated high-pitch CTA and hybrid ECG-gated CTA of the aorta using 512-slice CT. MATERIAL AND METHODS This retrospective study included 110 patients who underwent non-ECG-gated high-pitch CTA (group 1) or hybrid ECG-gated CTA (group 2) of the entire aorta. Interpretability, image noise, contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and the mean effective radiation dose were compared. RESULTS The mean image noise of the whole aorta was significantly lower (15.7 ± 1.8 HU vs. 16.5 ± 1.2 HU, P = 0.008) in group 1 than in group 2. The CNR (22.3 ± 4.7 vs. 20.0 ± 3.9, P < 0.001) and SNR (26.5 ± 4.9 vs. 23.2 ± 4.0, P < 0.001) were higher in group 2 compared with group 1. Neither group showed a significant difference in interpretability of the ascending aorta, cardiac chamber, aortic valve, right ostium, and left ostium (all P = 1). The mean effective radiation dose was significantly lower in group 1 than in group 2 (3.5 ± 0.9 mSv vs. 4.3 ± 0.8 mSv, P < 0.001). CONCLUSION The non-ECG-gated high-pitch technique shows significantly improved CNR and SNR due to reduced noise with lower radiation exposure. The interpretability of the cardiac structure, ascending aorta, aortic valve, and both ostia did not differ significantly between the two groups.

Abstract
459 Background: Suratadenoturev (OBP-301) is an oncolytic adenovirus that harbors a promoter of human telomerase reverse transcriptase ( hTERT) and is genetically modified to selectively replicate within and then lyse cancer cells. The aim of this study was to assess the safety and optimal dosage for intratumoral (IT) injection of OBP-301 in patients with advanced hepatocellular carcinoma (HCC). Methods: An open-label, non-comparative, phase I dose-escalation trial was performed in 20 patients who had refractory advanced HCC. OBP-301 was administered to the primary tumor using ultrasound guidance. A single IT injection of 1010 virus particles (VP) was administered to patients in the initial cohort (Cohort-1), and the subsequent single-dose cohorts received 1011 VP (Cohort-2), 1012 VP (Cohort-3), and 3×1012 VP (Cohort-4). A multiple dose cohort (Cohort-5) received 2×1012 VP × 3 times every 2 weeks. Each of the single-dose cohorts had 3 patients and there was a single escalating dose of OBP-301 from 1010 to 3×1012 VP. The multiple-dose cohort had 8 patients, and 6 of them received multiple escalating doses of 2×1012 VP ×3 times every 2 weeks. Results: There were 18 males and 2 females, and the median age was 59.39 years (range: 48.4–65.9). Patients had good tolerance of the single dose and multiple-dose regimens, and the maximum tolerated dose (MTD) was more than 6×1012 VP/patient. There was no evidence of toxicity with increasing dose, but there was a greater frequency of treatment-emergent adverse events (TEAEs) in Cohorts 4–5 than in Cohorts 1–3. The most common TEAEs related to OBP-301 were influenza-like illness (30%), pyrexia (15%), and fatigue, decreased platelet count, abdominal distension, and anemia (10% each). The overall intrahepatic mRECIST response occurred in 7 patients (39%) with confirmed stable disease (SD) and 11 (61%) with progressive disease (PD). The best target response occurred in 14 patients (78%) and 4 (22%) of them had PD. There was evidence of OBP-301 replication-dependent dissemination in the blood. Cohorts 4–5 had about 50% greater levels of CD8+ T cells in peripheral blood after OBP-301 injection. Conclusions: Multiple IT injections of OBP-301 are well-tolerated in advanced HCC. Although antitumor activity of the study medication alone would not be demonstrated obviously, SD observed as best local response was higher than as overall response. Improved anti-tumor efficacy can be achieved with adjusting viral injection volume to the target sites as well as with adopting the combination therapy with another immunothrapeutics in further study (JRCT ID: jRCT2033200223). Clinical trial information: NCT02293850.

Abstract
PURPOSE To evaluate the embolic effect of fish-derived gelatin microparticles (GMPs) and compare the degradation periods and biocompatibilities of different molecular weight (MW) GMPs in a rabbit model. METHODS GMPs were designed to degrade within 21 days (high MW GMP, 15-30 kDa) and 2 days (low MW GMP, 5-15 kDa) in vivo. Renal arteries of 24 rabbits were embolized using both high and low MW GMPs (155-350 µm). Rabbits were sacrificed either immediately after embolization, or after follow-up (F/U) angiogram on days 2 and 21 of embolization, respectively (4 rabbits in each of the 6 subgroups). Pathological changes of recanalized vessels were evaluated using the Banff classification. For the in vitro study, each type of GMP was mixed with normal saline and morphological changes were compared for 14 days. RESULTS Fish-derived GMPs showed effective embolization. On 2-day F/U angiography, occluded vessels were more recanalized to the peripheral branches in low MW group. On day 21, a parenchymal perfusion defect recovered to a greater extent in low MW group than that in high MW group. Mean Banff scores for intimal arteritis on 2-day F/U and interstitial fibrosis on 21-day F/U were higher in high MW group (1.75 ± 0.58 vs. 0.19 ± 0.4 and 2.56 ± 0.63 vs. 0.88 ± 0.89; P < .001). On in vitro assessment, low MW GMP lost the spherical shape and degraded, and was invisible on microscopy on day 6, whereas high MW GMP was only partially degraded after 2 weeks. CONCLUSION Fish-derived GMPs showed effective embolization in a rabbit model. Low MW GMPs degraded within 2 days with a low inflammatory response.

Abstract
BACKGROUND Even though radiologic diagnosis of bone tumors and tumor-like lesions is usually based on radiographs, radiographically faint imaging features sometimes remain challenging due to overlapping anatomical structures. PURPOSE To compare tomosynthesis with radiography for the evaluation of bone tumors and tumor-like lesions. MATERIAL AND METHODS Forty-seven bone tumors and tumor-like lesions were assessed with radiographs and tomosynthesis images. Two radiologists independently analyzed imaging features of lesions, including margin, periosteal reaction, cortical thinning, matrix mineralization, cortical destruction (such as pathologic fracture), and extraosseous soft-tissue extension. Computed tomography (CT) imaging was used as a reference method. Diagnostic performances of radiography and tomosynthesis were analyzed and compared based on sensitivity, specificity, accuracy, positive predictive value, and negative predictive value. Effective radiation dose was compared among the three imaging modalities by phantom studies. RESULTS Inter-observer variability (kappa value) for imaging features was slight to moderate on radiography (0.167-0.588), whereas it was nearly perfect on tomosynthesis (0.898-1.000) except for extraosseous soft-tissue extension (0.647 vs. 0.647). Tomosynthesis showed significantly higher sensitivity than radiography in evaluating the margin for bone tumors or tumor-like lesions (1.00 vs. 0.85; P = 0.016), and significantly higher accuracy than radiography in evaluating the margin and matrix mineralization for those (1.00 vs. 0.85; P = 0.016 and 0.91 vs.0.77; P = 0.023, respectively). In phantom studies, mean effective radiation doses were highest in order of CT, tomography, and radiography. CONCLUSION Tomosynthesis increases sensitivity and accuracy of the margin as well as accuracy of the matrix mineralization of bone tumors and tumor-like lesions compared to radiography.

Traumatic Hemothorax Caused by Thoracic Wall and Intrathoracic Injuries: Clinical Outcomes of Transcatheter Systemic Artery Embolization. Taehan Yongsang Uihakhoe Chi 2021; 82:923-935. [PMID: 36238056 PMCID: PMC9514418 DOI: 10.3348/jksr.2020.0116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
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 surgery, or those who undergoing emergency TAE for abdominal or pelvic hemostasis.

Abstract
Introduction: Micro-computed tomography with nanoparticle contrast agents may be a suitable tool for monitoring the time course of the development and progression of tumors. Here, we suggest a practical and convenient experimental method for generating and longitudinally imaging murine liver cancer models. Methods: Liver cancer was induced in 6 experimental mice by injecting clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeats-associated protein 9 plasmids causing mutations in genes expressed by hepatocytes. Nanoparticle agents are captured by Kupffer cells and detected by micro-computed tomography, thereby enabling longitudinal imaging. A total of 9 mice were used for the experiment. Six mice were injected with both plasmids and contrast, 2 injected with contrast alone, and one not injected with either agent. Micro-computed tomography images were acquired every 2- up to 14-weeks after cancer induction. Results: Liver cancer was first detected by micro-computed tomography at 8 weeks. The mean value of hepatic parenchymal attenuation remained almost unchanged over time, although the standard deviation of attenuation, reflecting heterogeneous contrast enhancement of the hepatic parenchyma, increased slowly over time in all mice. Histopathologically, heterogeneous distribution and aggregation of Kupffer cells was more prominent in the experimental group than in the control group. Heterogeneous enhancement of hepatic parenchyma, which could cause image quality deterioration and image misinterpretation, was observed and could be due to variation in Kupffer cells distribution. Conclusion: Micro-computed tomography with nanoparticle contrast is useful in evaluating the induction and characteristics of liver cancer, determining appropriate size of liver cancer for testing, and confirming therapeutic response.

Abstract
Purpose To evaluate the long-term radiologic and clinical outcomes of stent-graft placement for the treatment of post-pancreaticoduodenectomy arterial hemorrhage (PPAH) based on the imaging findings of stent-graft patency and results of liver function tests. Materials and Methods We retrospectively reviewed the medical records of nine consecutive patients who underwent stent-graft placement for PPAH between June 2012 and May 2017. We analyzed the immediate technical and clinical outcomes and liver function test results. Stent-graft patency was evaluated using serial CT angiography images. Results All stent-grafts were deployed in the intended position for the immediate cessation of arterial hemorrhage and preservation of hepatic arterial blood flow. Technical success was achieved in all nine patients. Eight patients survived after discharge, and one patient died on postoperative day 28. The median follow-up duration was 781 days (range: 28-1766 days). Follow-up CT angiography revealed stent-graft occlusion in all patients. However, serum aspartate aminotransferase or alanine aminotransferase levels in all patients were well below those observed in hepatic infarction cases. Conclusion Stent-graft placement is a safe and effective treatment method for acute life-threatening PPAH. Liver function and distal hepatic arterial blood flow were maintained postoperatively despite the high incidence of stent-graft occlusion observed on follow-up CT.

Abstract
The quark structure of the f_{2}(1270) meson has, for many years, been assumed to be a pure quark-antiquark (qq[over ¯]) resonance with quantum numbers J^{PC}=2^{++}. Recently, it was proposed that the f_{2}(1270) is a molecular state made from the attractive interaction of two ρ mesons. Such a state would be expected to decay strongly to final states with charged pions due to the dominant decay ρ→π^{+}π^{-}, whereas decay to two neutral pions would likely be suppressed. Here, we measure for the first time the reaction γp→π^{0}π^{0}p, using the CEBAF Large Acceptance Spectrometer detector at Jefferson Lab for incident beam energies between 3.6 and 5.4 GeV. Differential cross sections, dσ/dt, for f_{2}(1270) photoproduction are extracted with good precision due to low backgrounds and are compared to theoretical calculations.

Abstract
A first measurement of the longitudinal beam spin asymmetry A_{LU} in the semi-inclusive electroproduction of pairs of charged pions is reported. A_{LU} is a higher-twist observable and offers the cleanest access to the nucleon twist-3 parton distribution function e(x). Data have been collected in the Hall-B at Jefferson Lab by impinging a 5.498-GeV electron beam on a liquid-hydrogen target, and reconstructing the scattered electron and the pion pair with the CLAS detector. One-dimensional projections of the A_{LU}^{sinϕ_{R}} moments are extracted for the kinematic variables of interest in the valence quark region. The understanding of dihadron production is essential for the interpretation of observables in single-hadron production in semi-inclusive DIS, and pioneering measurements of single-spin asymmetries in dihadron production open a new avenue in studies of QCD dynamics.

Abstract
We have measured beam-spin asymmetries to extract the sinϕ moment A_{LU}^{sinϕ} from the hard exclusive e[over →]p→e^{'}nπ^{+} reaction above the resonance region, for the first time with nearly full coverage from forward to backward angles in the center of mass. The A_{LU}^{sinϕ} moment has been measured up to 6.6 GeV^{2} in -t, covering the kinematic regimes of generalized parton distributions (GPD) and baryon-to-meson transition distribution amplitudes (TDA) at the same time. The experimental results in very forward kinematics demonstrate the sensitivity to chiral-odd and chiral-even GPDs. In very backward kinematics where the TDA framework is applicable, we found A_{LU}^{sinϕ} to be negative, while a sign change was observed near 90° in the center of mass. The unique results presented in this Letter will provide critical constraints to establish reaction mechanisms that can help to further develop the GPD and TDA frameworks.

Abstract
Lymphoma is a common cause of nontraumatic chylothorax. Clinical success rates of thoracic duct embolization are lower in patients with nontraumatic chylothorax compared to patients with traumatic chylothorax. Herein, we report a case of nontraumatic chylothorax and lymphoma in a 77-year-old man managed with thoracic duct embolization. The chest tube drainage decreased but not was sufficient to enable removal of the chest tube. Therefore, a second embolization was performed through a direct puncture of the lymphatic mass in the lung, following which the chyle leakage ceased, and the chest tube was removed. The treatment strategy discussed in this report may be an effective therapeutic option for select patients with nontraumatic chylothorax.

Abstract
UNLABELLED Thyroid dysfunction is associated with the loss of bone density (osteoporosis). However, the connection between subclinical thyroid dysfunction and osteoporosis remains controversial. This study found no apparent association between subclinical hypothyroidism or subclinical hyperthyroidism and bone mineral density (BMD) in the lumbar spine and femur. INTRODUCTION The present study examined the relationship between subclinical thyroid dysfunction and BMD in healthy middle-aged adults. METHODS A total of 25,510 healthy Koreans with normal free thyroxine levels were enrolled from January 2011 to December 2016, and 91% of subjects visited only once. The average age of the 15,761 women was 45, and the average age of the 9749 men was 48. Levels of thyroid-stimulating hormone (TSH) and BMD were recorded in all subjects. BMD was measured using dual-energy X-ray absorptiometry. RESULTS No apparent association was found between subclinical thyroid dysfunction and BMD in the lumbar spine, femur-neck, and proximal femur sites compared with a euthyroid group. Age, body mass index (BMI), and postmenopausal status affected BMD in women, and only BMI affected BMD in men. Subclinical hypothyroidism was independently associated with a lower risk of osteoporosis (odds ratio 0.657, 95% confidence interval 0.464-0.930) in 4710 postmenopausal women. CONCLUSIONS No apparent association was found between subclinical hypothyroidism or subclinical hyperthyroidism defined on single TSH measurement and BMD at the lumbar spine and femur in a large cohort of middle-aged men and women. Subclinical hypothyroidism was independently associated with a lower risk of osteoporosis in postmenopausal women.

Abstract
CONTEXT Lespedeza cuneata G. Don (Fabaceae), has been used as a traditional treatment of various diseases. There is a report L. cuneata effects on hormone replacement therapy for endocrine-related disease. However, studies related to benign prostatic hyperplasia (BPH) have not been investigated. OBJECTIVE The effects of L. cuneata aqueous extract (LCW) on testosterone-induced prostatic hyperplasia (TPH) were examined. MATERIALS AND METHODS Male Wistar rats (10 weeks, 330-350 g) were randomly divided to 6 groups (n = 6): Control group; TPH group (3 mg/kg, s.c, daily); TPH + LCW (25, 50, 100 mg/kg); TPH + Finasteride 10 mg/kg for 6 weeks. At the end of treatment, histological change of prostate, serum dihydrotestosterone (DHT) level, mRNA expression of 5α-reductase, inflammatory factors, proliferating cell nuclear antigen (PCNA) and fibroblast growth factor-2 (FGF-2) in prostate were examined. Then, LCW was treated with BPH-1, a human BPH cell line, at 25, 50, 100 μg/mL for 24 h and examine mRNA level of androgen receptor (AR) and prostate-specific antigen (PSA). In addition, the content of vicenin-2 was analyzed. RESULTS LCW treatment of TPH inhibited serum DHT levels by 54.5, 51.2 and 54.1% and mRNA expression of 5α-reductase were inhibited 54.3, 61.3 and 73.6%, respectively. In addition, mRNA expression of inflammatory factors, PCNA and FGF-2 were decreased in the prostate of rats. Also, LCW attenuated mRNA level of AR and PSA in BPH-1 cell. The content of vicenin-2 in the LCW was analyzed to 0.89 mg/g. DISCUSSION AND CONCLUSIONS Based on the results, LCW is a potential pharmacological candidate for the treatment of prostatic hyperplasia.

Abstract
Although the dried root of Saposhnikovia divaricata (Turcz.) Schischk. (Umbelliferae) is a popular medicinal plant in East Asia, there has been no systemic toxicological evaluation of a water extract of Saposhnikoviae Radix (SRE). In this experiment, an oral acute and 13-week subchronic toxicological evaluations of SRE (500–5,000 mg/ kg body weight) were performed in both sexes of Crl:CD(SD) rats. Based on the results from mortality, clinical signs, effects on body weight and organ weight, clinical biochemistry, hematology, urinalysis, and histopathology, significant acute, 4-week repeated dose range finding (DRF) and 13-week subchronic toxicity of SRE was not observed in either sex of rats; thus, the no observed adverse effect level (NOAEL) was 5,000 mg (kg/day). To identify anti-hyperuricemia potential of SRE, the suppressive effect of SRE was determined in mice challenged with potassium oxonate (PO; 250 mg/kg) via intraperitoneal injection for 8 days (each group; n = 7). SRE supplementation suppressed the uric acid level in urine through significant xanthine oxidase (XO) inhibitory activity. Kidney dysfunctions were observed in PO-challenged mice as evidenced by an increase in serum creatinine level. Whereas, SRE supplementation suppressed it in a dose-dependent manner. Collectively, SRE was safe up to 5,000 mg (kg/day) based on NOAEL found from acute and 13-week subchronic toxicological evaluations. SRE had anti-hyperuricemia effect and lowered the excessive level of uric acid, a potential factor for gout and kidney failure.

Abstract
In the past two decades, deeply virtual Compton scattering of electrons has been successfully used to advance our knowledge of the partonic structure of the free proton and investigate correlations between the transverse position and the longitudinal momentum of quarks inside the nucleon. Meanwhile, the structure of bound nucleons in nuclei has been studied in inclusive deep-inelastic lepton scattering experiments off nuclear targets, showing a significant difference in longitudinal momentum distribution of quarks inside the bound nucleon, known as the EMC effect. In this Letter, we report the first beam spin asymmetry (BSA) measurement of exclusive deeply virtual Compton scattering off a proton bound in ^{4}He. The data used here were accumulated using a 6 GeV longitudinally polarized electron beam incident on a pressurized ^{4}He gaseous target placed within the CLAS spectrometer in Hall-B at the Thomas Jefferson National Accelerator Facility. The azimuthal angle (ϕ) dependence of the BSA was studied in a wide range of virtual photon and scattered proton kinematics. The Q^{2}, x_{B}, and t dependencies of the BSA on the bound proton are compared with those on the free proton. In the whole kinematical region of our measurements, the BSA on the bound proton is smaller by 20% to 40%, indicating possible medium modification of its partonic structure.

Abstract
Sorghum bicolor L. Moench is widely grown all over the world for food and feed. The effects of sorghum extracts on general inflammation have been previously studied, but its anti-vascular inflammatory effects are unknown. Therefore, this study investigated the anti-vascular inflammation effects of sorghum extract (SBE) and fermented extract of sorghum (fSBE) on human aortic smooth muscle cells (HASMCs). After the cytotoxicity test of the sorghum extract, a series of experiments were conducted. The inhibition effects of SBE and fSBE on the inflammatory response and adhesion molecule expression were measured using treatment with tumor necrosis factor-α (TNF-α), a crucial promoter for the development of atherosclerotic lesions, on HASMCs. After TNF-α (10 ng/mL) treatment for 2 h, then SBE and fSBE (100 and 200 μg/mL) were applied for 12h. Western blotting analysis showed that the expression of vascular cell adhesion molecule-1 (VCAM-1) (2.4-fold) and cyclooxygenase-2 (COX-2) (6.7-fold) decreased, and heme oxygenase-1 (HO-1) (3.5-fold) increased compared to the TNF-α control when treated with 200 μg/mL fSBE (P<0.05). In addition, the fSBE significantly increased the expression of HO-1 and significantly decreased the expression of VCAM-1 and COX-2 compared to the TNF-α control in mRNA level (P<0.05). These reasons of results might be due to the increased concentrations of procyanidin B1 (about 6-fold) and C1 (about 30-fold) produced through fermentation with Aspergillus oryzae NK for 48 h, at 37 °C. Overall, the results demonstrated that fSBE enhanced the inhibition of the inflammatory response and adherent molecule expression in HASMCs.

Abstract
Entecavir 0.5 mg (ETV) is widely used among treatment-naïve chronic hepatitis B (CHB) patients. However, 10%-30% of patients show partial virologic response (PVR) to the drug. If the hepatitis B virus (HBV) continues to replicate, the underlying liver disease may progress. Herein, we compared the efficacy of switching to tenofovir disoproxil fumarate (TDF) with that of continuing ETV in CHB patients with PVR to ETV. This was an open-label randomized controlled trial including CHB patients who had been receiving 0.5 mg of ETV for >12 months, but who still had detectable HBV DNA levels of >60 IU/mL without known resistance to ETV. Sixty patients were enrolled and 45 qualified for the study: Twenty-two patients were randomly assigned into the TDF group and 23 into the ETV group. After 12 months of treatment, the virologic response rate (HBV DNA <20 IU/mL) was significantly higher in the TDF group than in the ETV group, as measured using per-protocol analysis (55% vs 20%; P = .022) and intention-to-treat analysis (50% vs 17.4%; P = .020). The reduction in HBV DNA was greater (-1.13 vs -0.67 log10 IU/mL; P = .024), and the mean HBV DNA level was lower (1.54 vs 2.01 log10 IU/mL; P = .011) in the TDF group than in the ETV group. In conclusion, to achieve optimal response in CHB patients with PVR to ETV, switching to TDF would be a better strategy than continuing ETV. Appropriate modification of therapy would further improve the outcome of chronic HBV infection.

Abstract
Patients with chronic hepatitis C who achieve a sustained viral response after pegylated interferon therapy have a reduced risk of hepatocellular carcinoma, but the risk after treatment with direct-acting antivirals is unclear. We compared the rates of early development of hepatocellular carcinoma after direct-acting antivirals and after pegylated interferon therapy. We retrospectively analysed 785 patients with chronic hepatitis C who had no history of hepatocellular carcinoma (211 treated with pegylated interferon, 574 with direct-acting antivirals) and were followed up for at least 24 weeks after antiviral treatment. De novo hepatocellular carcinoma developed in 6 of 574 patients receiving direct-acting antivirals and in 1 of 211 patients receiving pegylated interferon. The cumulative incidence of early hepatocellular carcinoma development did not differ between the treatment groups either for the whole cohort (1.05% vs 0.47%, P = .298) or for those patients with Child-Pugh Class A cirrhosis (3.73% vs 2.94%, P = .827). Multivariate analysis indicated that alpha-fetoprotein level >9.5 ng/mL at the time of end-of-treatment response was the only independent risk factor for early development of hepatocellular carcinoma in all patients (P < .0001, hazard ratio 176.174, 95% confidence interval 10.768-2882.473) and in patients treated with direct-acting agents (P < .0001, hazard ratio 128.402, 95% confidence interval 8.417-1958.680). In conclusion, the rate of early development of hepatocellular carcinoma did not differ between patients treated with pegylated interferon and those treated with direct-acting antivirals and was associated with the serum alpha-fetoprotein level at the time of end-of-treatment response.

Abstract
BACKGROUND A widespread scabies infestation, associated with long-term residence in nursing homes, is becoming an issue in high-income countries. Mineral oil examination is regarded as the gold standard in diagnosing scabies, but the sensitivity of this method is generally low - approximately 50%. Molecular techniques may contribute to enhancing the sensitivity of current tests for laboratory diagnosis of human scabies. OBJECTIVES To develop new primers for a nested polymerase chain reaction (PCR) for the cytochrome c oxidase subunit 1 (cox1) gene of Sarcoptes scabiei var. hominis to increase the sensitivity of a previously developed conventional PCR. METHODS Patients with clinically suspected scabies underwent dermoscopy-guided skin scraping with microscopic examination. The diagnosis was positive for scabies when mites or eggs were found under the microscope, and patients were then designated as 'microscopy positive'. Patients who presented with negative microscopic results were placed in the 'microscopy-negative' group. Skin scrapings were collected from both groups for PCR. RESULTS Of the total 63 samples, 28 were microscopy positive and 35 were negative with no differences in sex and age between the two groups. All microscopically proven cases of scabies were positive using the cox1 nested PCR. Among microscopy-negative samples, S. scabieiDNA was detected in nine. If sensitivity of the cox1 nested PCR is considered 100% [95% confidence interval (CI) 90·5-100], then sensitivity of microscopy is 75·7% (95% CI 58·8-88·2; P = 0·004). CONCLUSIONS Nested PCR can be successfully used as an alternative method for diagnosing suspected scabies. Therefore, infection control measures and treatments can be initiated before significant transmission occurs, minimizing the risk of outbreaks.

Abstract
PURPOSE Bisphenol A (BPA) has been regarded as a possible risk factor for reproductive health. We examined potential reproductive health benefits of Lespedeza cuneata ethanol extract (LCE). Previously, Lespedeza cuneata showed many therapeutic effects. However, the protective effect of LCE on BPA-induced testicular dysfunction and its mechanisms have not been precisely studied. METHODS Mice were randomly divided into six groups (n = 7). Sperm counts and motility were measured by light microscope. Testosterone, total cholesterol, triglycerides, HDL, LDL-cholesterol, glucose, free fatty acids, hs-CRP, Angiotensinogen, Angiotensin II, GOT, GPT, TBARS, GSH, CAT, and SOD1 were measured in mouse serum. The potential protective effects of the LCE on mouse sertoli cells were evaluated. RESULTS Oral administration of LCE in BPA-exposed male mice restored testis weight, sperm count, motility, and testosterone levels by inhibiting markers in serum. In addition, treatment with LCE in BPA-treated TM4 sertoli cells recovered cell viability by attenuating Bax expression and activating caspase 3 and PARP. CONCLUSIONS These results indicate that LCE prevented BPA-induced testicular dysfunction and cell viability in BPA-treated TM4 sertoli cells. Our study also suggests that LCE has the potential to protect male reproductive health.

Abstract
Objective Postpancreatectomy hemorrhage (PPH) is an uncommon but serious complication of Whipple surgery. To evaluate the radiologic features associated with late PPH at the first postoperative follow up CT, before bleeding. Materials and Methods To evaluate the radiological features associated with late PPH at the first follow-up CT, two radiologists retrospectively reviewed the initial postoperative follow-up CT images of 151 patients, who had undergone Whipple surgery. Twenty patients showed PPH due to vascular problem or anastomotic ulcer. The research compared CT and clinical findings of 20 patients with late PPH and 131 patients without late PPH, including presence of suggestive feature of pancreatic fistula (presence of air at fluid along pancreaticojejunostomy [PJ]), abscess (fluid collection with an enhancing rim or gas), fluid along hepaticojejunostomy or PJ, the density of ascites, and the size of visible gastroduodenal artery (GDA) stump. Results CT findings including pancreatic fistula, abscess, and large GDA stump were associated with PPH on univariate analysis (p ≤ 0.009). On multivariate analysis, radiological features suggestive of a pancreatic fistula, abscess, and a GDA stump > 4.45 mm were associated with PPH (p ≤ 0.031). Conclusion Early postoperative CT findings including GDA stump size larger than 4.45 mm, fluid collection with an enhancing rim or gas, and air at fluid along PJ, could predict late PPH.

Abstract
Background Using the hybrid electrocardiogram (ECG)-gated computed tomography (CT) technique, assessment of entire aorta, coronary arteries, and aortic valve can be possible using single-bolus contrast administration within a single acquisition. Purpose To compare the image quality of hybrid ECG-gated and non-gated CT angiography of the aorta and evaluate the effect of a motion correction algorithm (MCA) on coronary artery image quality in a hybrid ECG-gated aorta CT group. Material and Methods In total, 104 patients (76 men; mean age = 65.8 years) prospectively randomized into two groups (Group 1 = hybrid ECG-gated CT; Group 2 = non-gated CT) underwent wide-detector array aorta CT. Image quality, assessed using a four-point scale, was compared between the groups. Coronary artery image quality was compared between the conventional reconstruction and motion correction reconstruction subgroups in Group 1. Results Group 1 showed significant advantages over Group 2 in aortic wall, cardiac chamber, aortic valve, coronary ostia, and main coronary arteries image quality (all P < 0.001). All Group 1 patients had diagnostic image quality of the aortic wall and left ostium. The MCA significantly improved the image quality of the three main coronary arteries ( P < 0.05). Moreover, per-vessel interpretability improved from 92.3% to 97.1% with the MCA ( P = 0.013). Conclusion Hybrid ECG-gated CT significantly improved the heart and aortic wall image quality and the MCA can further improve the image quality and interpretability of coronary arteries.

Abstract
Introduction Informed consent is essential patient's right even in overcrowded emergency department (ED). We compared the effect of animation-assisted informed consent using tablet PC with the standard informed consent for contrast-enhanced computed-tomography (CT) in ED. Methods We included 150 patients scheduled to undergo contrast-enhanced CT in ED from November 2010 through January 2011. Participants were randomised to either animation-assisted information (AAI) (n=75) or standard verbal information (SVI) group (n=75). AAI was provided by tablet personal computer (PC); and SVI by clinicians. All participants completed 10-point scale questionnaires after the CT scan. The questionnaires included two main categories – understanding and satisfaction of informed consent. Results Participants in the AAI group had a better understanding of purpose (8.95±1.48 vs. 8.32±1.88, p=0.026) and methods (8.93±1.43 vs. 8.37±1.83, p=0.048) of CT scans compared to participants in the SVI group. Every score in satisfaction categories was significantly higher in the AAI group. In the SVI group, relatively low-educated participants had a lower score in understanding when compared with university-educated participants (7.53±2.28 vs. 8.52±1.40, p=0.029). Regardless of education level, understanding score was high in the AAI group (8.73±1.27 vs. 8.57±1.50, p=0.71). Conclusions Participants receiving animation assisted informed consent with tablet PC shows a higher degree of understanding and satisfaction compared with patients receiving standard verbal informed consent. Particularly in patients with lower education, animation-assisted informed consent may be better for understanding of contrast-enhanced CT.

Abstract
Introduction The events of 11th September 2001, and the subsequent anthrax attacks in the United States brought the threat of bioterrorism to the forefront of concern for public health departments. Moreover, the rising confrontation between North and South Korea emphasizes the possibility of aggression with biological weapons and our vulnerability to bioterrorism. While the importance of physicians' interests and management ability is becoming more critical, no studies have yet been undertaken in Korea to assess whether primary care physicians are well informed and capable of managing bioterrorism. This study evaluates the awareness and response of young male physicians to potential bioterrorism in South Korea. Method A total of 692 young male physicians completed the knowledge and awareness survey during the education period of military service on 9th April 2005. Results Forty-five percent of the participants responded that the possibility of biological warfare in Korea was high. The level of bioterrorism knowledge, however, was low. Eighty-seven percent acknowledged the necessity of education and training for bioterrorism, and 69.9% were willing to accept education and training in bioterrorism preparedness. Conclusion These findings suggest that young physicians should receive continuous education and training to improve preparedness for biological terrorism and warfare in South Korea.

Abstract
Background Escalator-related injuries have been considered uncommon and most likely to occur in children. In this study, we described the epidemiology of these injuries with focus on the aged population in order to determine whether escalators are safe for the aged, and to obtain information to help in preventing escalator-related injuries. Methods A prospective survey was taken to identify the number and nature of these injuries from May 2004 to December 2008. We enrolled patients who had sustained escalator-related injuries. A standard list of questions and answers were recorded by the emergency physician. A total of 104 questionnaires were completed during the study period. Results The average patient age was 59.2±24.0 years (range 1-94). There were 64 (61.5%) females. Only 11 (10.6%) were younger than 15 years old, and 59 (56.7%) were aged 65 or above; 35 (59.3%) of the aged people were injured while standing on the escalator. However, out of the 45 patients younger than age 65, 22 (48.9%) were injured from walking on a moving escalator. Head injury was the commonest site of injury overall and all were due to fall or slipping down. Conclusions Escalator-related injuries are not as rare as previously believed and the aged population 65 years old or above is the highest risk group. In particular, walking on a moving escalator was the main cause of injury in people under age 65. Therefore, primary prevention strategies are needed to prevent users from walking on escalators, especially young people, and educate aged people the safe utilization of escalators to prevent slip and fall injuries.

Abstract
Airbags and seat belts are safety devices in automobiles. First invented in the 1950s, they are now commonplace in most automobiles. However, a seat occupant may sustain unexpected injuries even if the airbag deploys in a car collision. We describe a patient who was suspected of simultaneously sustaining haemopericardium and liver laceration during the “punch out” and “membrane force” phases of airbag deployment. The patient's vital signs stabilised after an emergency pericardiocentesis was performed. In a car accident when high-energy injury is suspected despite airbag deployment, computed tomography of the chest and abdomen or echocardiography should be considered because of the possibility of abdominal solid organ and chest injury.

Abstract
Cases of deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE) related to the isolated risk factor of uterine myoma are very rare. In a setting of emergency department (ED), it is unlikely that uterine myoma would be suspected as the primary cause of symptoms in a patient with thromboembolism. We presented a 44-year-old woman who visited the ED for DVT presenting with right lower leg swelling with an underlying cause of a huge uterine myoma. Various aetiologies, including obstetric and gynaecological causes (especially uterine myoma), should be considered in female patients visiting the ED with suspected DVT or PTE.

Abstract
Objectives When we perform chest compression on a patient on a bed, the mattress and bed frame can be depressed together with the patient's chest. This study was conducted to assess whether bed frame deflection occurred during chest compressions. Methods We designed a firm bed (“bed like the ground,” BLG) to assess the bed frame deflection in the Stryker Trauma Stretcher (STS) and the ER stretcher cart (ER-SC). The STS included a soft mattress and the ER-SC a hard mattress. We performed 50 continuous chest compressions on the Resusci Anne Skill Reporter with CPRmeter in each experiment. The experiments were done in four settings. Test 1 included the BLG; test 2 included a mattress and backboard on each bed; test 3 included the mattress of each bed and a backboard on the BLG; and test 4 included the mattress of each bed on the BLG. We calculated the mattress and bed frame deflections using the gaps of compression depths between the values measured by Resusci Anne and CPRmeter. Results The mattress deflections of the STS and ER-SC mattress were determined to be 11.2 and 0.67 mm, respectively. The bed frame deflection for the STS and ER-SC were 0.95 and 5.17 mm, respectively. Conclusion The study confirms that bed frame deflection will occur when we perform chest compressions on the manikin lying on a bed. Additionally, the bed frame deflections differ depending on the type of bed. (Hong Kong j.emerg.med. 2016;23:35-41)

Abstract
Objective This study aims to determine whether or not cardiopulmonary resuscitation (CPR) skills differ according to different instructional models for CPR education and training for junior and senior high school students. Methods This was a prospective and randomised study including 519 junior and senior high school students. After the lecture on CPR, students practiced the skill on the manikin. Group 1 used model 1 and Group 2 used model 2 for practical training and practical skills and CPR performance quality were evaluated. Results Data from skill tests were analysed in 229 students in group 1 and 210 students in group 2. The total score of sequence skill tests was 17.8±2.0 points. During 2 cycles, no chest elevation was observed in 33.3% and was significantly lower in group 1. There were no significant differences in the frequency of proper ventilation and in ventilation volume between the 2 groups. Excessive ventilation was more frequently observed in group 1 and insufficient ventilation was observed more frequently in group 2. The percentage of the frequency of a proper chest compression rate was 80.5±31.2% and there were no significant differences in proper and insufficient depths, mean rate and recoil of the chest in chest compression between the 2 groups. Conclusions There were differences in CPR skills according to different CPR training manikins. Therefore, certain conditions seem to be considered in selection of instructional models for CPR psychomotor skills. (Hong Kong j.emerg.med. 2011;18:375-382)

Abstract
Pneumomediastinum is an uncommon radiographic finding resulting from various causes, such as trauma, infection and unknown causes. The pneumomediastinum due to minor trauma is rarely reported and treatment and diagnostic process is not established. We report on a 20-year-old female patient who initially presented with neck pain and dyspnoea following manual strangulation. Her chest X-ray and computed tomography (CT) of neck imaging showed subcutaneous emphysema and extensive pneumomediastinum, but pneumothorax was not shown. She was transferred to the thoracic surgery and admitted to the general ward. The patient's condition improved and she was discharged on the sixth hospital day. In conclusion, patients with pneumomediastinum following a minor strangulation injury can be observed alone without invasive testing or repeated imaging. CT scans are of great value for safe observation in determined patients and for the further evaluation of pneumomediastinum.

Abstract
Segmental arterial mediolysis is a rare vascular disease that leads to spontaneous intra-abdominal haemorrhage, which causes shock and bowel ischaemia, and is associated with a high mortality rate. Here, we present a case of spontaneous intra-abdominal haemorrhage due to segmental arterial mediolysis in a patient who underwent oesophagocolojejunostomy for synchronous triple primary cancer, which was treated successfully by coil embolization. We conclude that a preoperative angiogram is necessary to detect vascular abnormalities, and in cases with severe haemorrhage, an urgent endovascular procedure is the treatment of choice.

Abstract
BACKGROUND Endovascular aneurysm repair (EVAR) has dramatically changed the management of abdominal aortic aneurysms (AAAs) as the number of open aneurysm repairs have declined over time. This report compares AAA-related demographics, operative data, complications, and mortality after treatment by open aneurysm repair or EVAR. METHODS We retrospectively reviewed 136 patients with AAAs who were treated over an 8-year time period with open aneurysm repair or EVAR. RESULTS The mean age of the EVAR group was higher than that of the open repair group (p=0.001), and hospital mortality did not differ significantly between groups (p=0.360). However, overall survival was significantly lower in the EVAR group (p=0.033). CONCLUSION Although EVAR is the primary treatment modality for elderly patients, it would be ideal to set slightly more stringent criteria within the anatomical guidelines contained in the instructions for use of the EVAR device when treating younger patients.

Abstract
BACKGROUND No clear association between hepatitis B virus (HBV) infection and atopic dermatitis (AD) has been established. Some studies have reported that subjects with HBV had an increased risk of atopy; other studies reported an inverse association between HBV seropositivity and allergic diseases. OBJECTIVE We evaluated the association between AD and hepatitis B antigen (HBsAg) positivity using Korean National Health and Nutrition Examination Survey data. METHODS In total, 14 776 participants aged >19 years were included in the analysis. Multiple logistic regression analyses were used to evaluate the odds ratio of HBsAg positivity in association with AD and asthma. RESULTS The prevalence of HBsAg positivity was lower in individuals with AD than in those without AD (mean [SE], 0.7% [0.4] vs. 3.7% [0.2]; P < 0.001). However, HBsAg positivity was not significantly associated with asthma (3.7% [0.2] vs. 2.8% [0.8]; P < 0.001). HBsAg positivity decreased the risk of AD significantly (OR = 0.223; 95% CI = 0.069-0.72). CONCLUSIONS This study demonstrates an inverse association between AD and HBsAg positivity using a nationwide, population-based, cross-sectional health examination and survey.

Abstract
Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2 blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

Abstract
Cell death-inducing DFF45-like effector (CIDE) B is a member of the CIDE family of apoptosis-inducing factors. In the present study, we detected a single nucleotide polymorphism (SNP), c.414G>A, which corresponds to the synonymous SNP 414Arg, in CIDE-B in the Berkshire pigs. We also analyzed the relationships between the CIDE-B SNP and various meat quality traits. The SNP was significantly associated with post-mortem pH24h, water-holding capacity (WHC), fat content, protein content, drip loss, post-mortem temperature at 12 h (T12) and 24 h (T24) in a co-dominant model (P < 0.05). A significant association was detected between the SNP and post-mortem pH24h, fat content, protein content, drip loss, shear force, and T24 in gilts; and color parameter b*, WHC, and T24 in barrows (P < 0.05). The SNP was significantly correlated with the fat content, and CIDE-B mRNA expression was significantly upregulated during the early stage of adipogenesis, suggesting that CIDE-B may contribute towards initiation of adipogenesis (P < 0.05). Furthermore, CIDE-B mRNA was strongly expressed in the liver, kidney, large intestine, and small intestine, and weakly expressed in the stomach, lung, spleen, and white adipose tissue. These results indicate that the CIDE-B SNP is closely associated with meat quality traits and may be a useful DNA marker for improving pork quality.

Abstract
AIM The aim of this study was to investigate the effect of yttrium-90 radioembolization on the outcome of Asian patients with early to advanced stage hepatocellular carcinoma (HCC). METHODS Sixty-two patients were screened and 50 patients (80.6%) were eligible. Response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST), and overall survival was estimated using the Kaplan-Meier method. RESULTS The Barcelona Clinic Liver Cancer (BCLC) stage was A in 40% of patients, B in 24%, and C in 36%; 66% of patients had hepatitis B virus infections. According to RECIST criteria, partial responses occurred in 40% of patients, and stable disease was achieved in 46%. Tumor response was significantly associated with BCLC stage (P = 0.003). The median overall time to progression was 5.8 months (range, 0.9-46.1 months). Follow-up treatments after radioembolization were carried out in 31 patients due to remnant HCC (n = 18) or HCC progression (n = 13). The median overall survival was 40.9 months (95% confidence interval, 10.2-71.6 months). Treatment was tolerable except for one lung toxicity and two hepatic toxicities. CONCLUSION Yttrium-90 radioembolization appears to be well tolerated and effective in Asian patients with BCLC stage A-C HCC. Follow-up treatments after radioembolization can be safely provided.
