Objective: This study evaluated the accuracy of the pre-hospital shock index multiplied by the AVPU scale (PSIAVPU) as a predictor of massive transfusion (MT) and traumatic coagulopathy. Methods: This research was a retrospective single-center study that included patients consecutively presenting to a trauma center between 2017 and 2020. The predictive value of the PSIAVPU for MT, in-hospital mortality, and traumatic coagulopathy was measured using the area under the curve (AUC) of the receiver operating characteristic curve. The AUC of the PSIAVPU was compared with the Reverse Shock Index multiplied by the Glasgow Coma Scale (rSIG) measured at the trauma center presentation. Results: One thousand seven hundred and ninety-two patients were included, of which 163 patients (9.09%) received MT and 195 patients (10.88%) died during their hospital stay. Traumatic coagulopathy was observed in 245 patients. The AUC values for the PSIAVPU in terms of predicting MT, hospital mortality, and traumatic coagulopathy were 0.755, 0.752, and 0.736, respectively. Conclusion In patients with trauma, the predictive power of the PSIAVPU was higher than that of the prehospital shock index and was comparable to that of the rSIG. The PSIAVPU is a useful indicator that can be used easily and quickly for trauma patients at the prehospital stage.

The global burden of chronic liver disease (CLD) is substantial. Due to the limited indication of and accessibility to antiviral therapy in viral hepatitis and lack of effective pharmacological treatment in nonalcoholic fatty liver disease, the beneficial effects of antidiabetics and non–antidiabetics in clinical practice have been continuously investigated in patients with CLD. In this narrative review, we focused on non-antidiabetic drugs, including ursodeoxycholic acid, silymarin, dimethyl4,4’-dimethoxy-5,6,5’,6’-dimethylenedixoybiphenyl-2,2’-dicarboxylate, L-ornithine L-aspartate, branched chain amino acids, statin, probiotics, vitamin E, and aspirin, and summarized their beneficial effects in CLD. Based on the antioxidant, anti-inflammatory properties, and regulatory functions in glucose or lipid metabolism, several non–antidiabetic drugs have shown beneficial effects in improving liver histology, aminotransferase level, and metabolic parameters and reducing risks of hepatocellular carcinoma and mortality, without significant safety concerns, in patients with CLD. Although the effect as the centerpiece management in patients with CLD is not robust, the use of these non-antidiabetic drugs might be potentially beneficial as an adjuvant or combined treatment strategy.

Objective: The aim of this study was to compare the survival rates of Korean females aged 40 to 49 years with breast cancer detected by supplemental screening ultrasound (US) or screening mammography alone. Materials and Methods: This single-institution retrospective study included 240 patients with breast cancer (mean age, 45.1 ± 2.8 years) detected by US or mammography who had undergone breast surgery between 2003 and 2008. Medical records were reviewed for clinicopathologic characteristics and detection methods. Disease-free survival (DFS) and overall survival (OS) were compared between patients with breast cancer in the US and mammography groups using the log-rank test. Multivariable cox regression analysis was used to identify independent variables associated with DFS and OS. Results: Among the 240 cases of breast cancer, 43 were detected by supplemental screening US and 197 by screening mammography (mean follow-up: 7.4 years, 93.3% with dense breasts). There were 19 recurrences and 16 deaths, all occurring in the mammography group. While the US group did not differ from the mammography group in tumor stage, the patients in this group were more likely to undergo breast-conserving surgery and radiation therapy than the mammography group.The US group also showed better DFS (p = 0.016); however, OS did not differ between the two groups (p = 0.058). In the multivariable analysis, the US group showed a lower risk of recurrence (hazard ratio, 0.097; 95% confidence interval, 0.001–0.705) compared to the mammography group. Conclusion Our study found that Korean females aged 40–49 years with US-detected breast cancer showed better DFS than those with mammography-detected breast cancer. However, there were no statistically significant differences in OS.

Purpose: Alpha-fetoprotein (AFP) is a prognostic marker for hepatocellular carcinoma (HCC). We investigated the prognostic value of AFP levels in patients who achieved complete response (CR) to transarterial chemoembolization (TACE) for HCC. Materials and Methods: Between 2005 and 2018, 890 patients with HCC who achieved a CR to TACE were recruited. An AFP responder was defined as a patient who showed elevated levels of AFP (>10 ng/mL) during TACE, but showed normalization or a >50% reduction in AFP levels after achieving a CR. Results: Among the recruited patients, 569 (63.9%) with naïve HCC and 321 (36.1%) with recurrent HCC after complete resection were treated. Before TACE, 305 (34.3%) patients had multiple tumors, 219 (24.6%) had a maximal tumor size >3 cm, and 22 (2.5%) had portal vein tumor thrombosis. The median AFP level after achieving a CR was 6.36 ng/mL. After a CR, 473 (53.1%) patients experienced recurrence, and 417 (46.9%) died [median progression-free survival (PFS) and overall survival (OS) of 16.3 and 62.8 months, respectively]. High AFP levels at CR (>20 ng/mL) were independently associated with a shorter PFS [hazard ratio (HR)=1.403] and OS (HR=1.284), together with tumor multiplicity at TACE (HR=1.518 and 1.666, respectively). AFP non-responders at CR (76.2%, n=359 of 471) showed a shorter PFS (median 10.5 months vs. 15.5 months, HR=1.375) and OS (median 41.4 months vs. 61.8 months, HR=1.424) than AFP responders (all p=0.001). Conclusion High AFP levels and AFP non-responders were independently associated with poor outcomes after TACE. AFP holds clinical implications for detailed risk stratification upon achieving a CR after TACE.

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.

Background/Aims: Prognostic models are lacking for patients with recurrent hepatocellular carcinoma (HCC) following surgical resection. This study devised and validated a new hepatoma arterial-embolization prognostic (HAP) score optimized for use in patients undergoing treatment with transarterial chemoembolization (TACE) for recurrence subsequent to surgical resection of HCC. Methods: Training cohort (n=424) and validation cohort (n=350) patients with recurrent HCC after resection treated with TACE between 2003 and 2016 were enrolled. Cox regression and area under the receiver operating characteristic curve (AUC) analyses were used to identify risk factors for survival and to calculate the predictive performance of risk scores, respectively. Results: The median age of the study population was 59.2 years. α-Fetoprotein >400 ng/mL (hazard ratio [HR]=1.815), serum albumin ≤3.5 g/dL (HR=1.966), tumor number ≥2 (HR=1.425), tumor size >5 cm at resection or recurrence (HR=1.356), segmental portal vein invasion at resection or recurrence (HR=2.032), and time from resection to recurrence ≤1 years (HR=1.849) independently predicted survival (all p<0.05). The postoperative HAP (pHAP) model based on the rounded HRs of these variables showed an AUC of 0.723 for predicting survival at 3 years, which was significantly higher than AUCs of other HAP-based models, including HAP, modified HAP, and modified HAP-II scores (0.578-0.621) (all p<0.05). The accuracy of pHAP was maintained in the entire cohort (n=774; AUC=0.776 at 3 years). Conclusions A new pHAP score optimized for patients treated with TACE due to recurrent HCC after resection showed acceptable accuracy and was externally validated. Further studies of means by which to select treatment options other than TACE for high-risk patients according to pHAP scores are warranted.
