PURPOSE: The mortality rate for severely injured patients with the injury severity score (ISS) ≥16 has decreased in Germany. There is robust evidence that mortality is influenced not only by the acute trauma itself but also by physical health, age and sex. The aim of this study was to identify other possible influences on the mortality of severely injured patients. METHODS: In a matched-pair analysis of data from Trauma Register DGU®, non-surviving patients from Germany between 2009 and 2014 with an ISS≥16 were compared with surviving matching partners. Matching was performed on the basis of age, sex, physical health, injury pattern, trauma mechanism, conscious state at the scene of the accident based on the Glasgow coma scale, and the presence of shock on arrival at the emergency room. RESULTS: We matched two homogeneous groups, each of which consisted of 657 patients (535 male, average age 37 years). There was no significant difference in the vital parameters at the scene of the accident, the length of the pre-hospital phase, the type of transport (ground or air), pre-hospital fluid management and amounts, ISS, initial care level, the length of the emergency room stay, the care received at night or from on-call personnel during the weekend, the use of abdominal sonographic imaging, the type of X-ray imaging used, and the percentage of patients who developed sepsis. We found a significant difference in the new injury severity score, the frequency of multi-organ failure, hemoglobine at admission, base excess and international normalized ratio in the emergency room, the type of accident (fall or road traffic accident), the pre-hospital intubation rate, reanimation, in-hospital fluid management, the frequency of transfusion, tomography (whole-body computed tomography), and the necessity of emergency intervention. CONCLUSION Previously postulated factors such as the level of care and the length of the emergency room stay did not appear to have a significant influence in this study. Further studies should be conducted to analyse the identified factors with a view to optimising the treatment of severely injured patients. Our study shows that there are significant factors that can predict or influence the mortality of severely injured patients.

BACKGROUND AND OBJECTIVES: Although anticoagulation with warfarin is recommended as an international normalized ratio (INR) of prothrombin time between 2.0 and 3.0 and mean time in the therapeutic range (TTR) ≥70%, little has been proven that universal criteria might be suitable in Korean atrial fibrillation (AF) patients.METHODS: We analyzed 710 patients with non-valvular AF who took warfarin. INR value and clinical outcomes were assessed during 2-year follow-up. Intensity of anticoagulation was assessed as mean INR value and TTR according to target INR range. Primary net-clinical outcome was defined as the composite of new-onset stroke and major bleeding. Secondary net-clinical outcome was defined as the composite of new-onset stroke, major bleeding and death.RESULTS: Thromboembolism was significantly decreased when mean INR was over 1.6. Major bleeding was significantly decreased when TTR was over 70% and mean INR was less than 2.6. Mean INR 1.6–2.6 significantly reduced thromboembolism (adjusted hazard ratio [HR], 0.40; 95% confidence interval [CI], 0.19–0.85), major bleeding (HR, 0.43; 95% CI, 0.23–0.81), primary (HR, 0.50; 95% CI, 0.29–0.84) and secondary (HR, 0.45; 95% CI, 0.28–0.74) net-clinical outcomes, whereas mean INR 2.0–3.0 did not. Simultaneous satisfaction of mean INR 1.6–2.6 and TTR ≥70% was associated with significant risk reduction of major bleeding, primary and secondary net-clinical outcomes.CONCLUSIONS: Mean INR 1.6–2.6 was better than mean INR 2.0–3.0 for the prevention of thromboembolism and major bleeding. However, INR 1.6–2.6 and TTR ≥70% had similar clinical outcomes to INR 2.0–3.0 and TTR ≥70% in Korean patients with non-valvular AF.

OBJECTIVE: Unperforated and perforated acute appendicitis need to be differentiated because appendicitis with a free perforation requires an emergency operation to prevent contamination inside the bowel from spreading into the peritoneal cavity. The sensitivity of imaging tests is not reliable enough alone for determining the existence of a perforation. The aim of this study was to determine the differences in laboratory values between unperforated and perforated acute appendicitis to help distinguish perforated acute appendicitis. METHODS: The laboratory values and demographic data of a total of 175 patients who visited the emergency room and were diagnosed with acute appendicitis were collected. The time elapsed from symptom presentation to the ER visit, length of admission, patient demographics, and laboratory values, including sex, age, leukocyte count, neutrophil %, neutrophil count, C-reactive protein (CRP), platelet count, prothrombin time (PT), activated partial thromboplastin time, international normalized ratio (INR), serum glucose, blood urea nitrogen, creatinine, total and direct bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase were analyzed. RESULTS: The factors associated with appendix perforations were an elevated leukocyte count, neutrophil count, neutrophil %, CRP, serum glucose and total bilirubin; and delayed PT and INR. CONCLUSION: Acute appendicitis patients without definite imaging evidence of the perforation but with the laboratory values suggesting a perforation, such as elevated leukocyte count, neutrophil count, neutrophil %, CRP, serum glucose, and total bilirubin; and delayed PT, and INR should raise concern for a possible undiscovered perforation.

Intramuscular hematomas on the psoas muscle are rare and usually occur as a result of trauma, iatrogenic etiology during lumbar surgery, rupture of the aortic aneurysm, and hematologic diseases. The incidence of spontaneous psoas muscle hematomas has slowly increased as a result of using anticoagulation and antiplatelet agents. Magnetic resonance (MR) imaging is a more sensitive option compared to computed tomography (CT) when diagnosing a hematoma. Coronal T2-weighted images are more useful. CT imaging is also useful to establish the rapid diagnosis of hematoma. When a prolonged prothrombin time and international normalized ratio and decrease platelet count are noted, psoas muscle hematomas should be considered, if there was no lesion in the spinal canal. Most hematomas resolve spontaneously without clinical complications if the hematoma is not large or it is not compressing the surrounding important structures, irrespective of cause.

BACKGROUND: Liver fibrosis evaluation is an important issue in chronic liver disease patients. We aimed to develop noninvasive liver fibrosis biomarkers based on transient elastography (TE, FibroScan®) through retrospective review of clinicopathological data. METHODS: We recruited 278 chronic hepatitis B patients who underwent Fibroscan and HBV DNA testing. A total of 115 HBeAg-positive and 159 HBeAg-negative chronic hepatitis B patients were analyzed. A total of 100 hepatitis C patients were analyzed. Successful fibroscan data, gamma-glutamyl transferase (GGT) to platelet ratio (GPR), platelet count, AST, ALT, international normalized ratio of prothrombin time, total cholesterol, triglycerides, bilirubin, mean platelet volume, AST to platelet ratio index, fibrosis index based on four factors (FIB-4), neutrophil to lymphocyte ratio (NLR), and NLR to platelet ratio were analyzed to determine the new noninvasive markers for assessing liver fibrosis. RESULTS: Elevated GPR (OR=9.1, P=0.011) and FIB-4 (OR=2.3, P=0.01) were associated with greater risk of liver fibrosis in chronic hepatitis B patients. FIB-4 (OR=6.04, P=0.005) was a risk factor for liver fibrosis in HBeAg-positive patients. FIB-4 (OR=2.371, P=0.015) and GPR (OR=33.78, P=0.003) were liver fibrosis risk factor in HBeAg-negative patients. In chronic hepatitis C patients, GGT (OR=1.033, P=0.002), triglyceride (OR=−0.990, P=0.038) and FIB-4 (OR=3.499, P=0.006) showed statistical significances. The AUCs were 0.816 in FIB-4 (P<0.001) and 0.849 in GPR (P<0.001). CONCLUSIONS: FIB-4 and GPR may be useful blood markers for assessing liver fibrosis in chronic hepatitis B and hepatitis C patients. Further well-designed prospective study is required to validate these noninvasive blood markers in clinical practice.

PURPOSE: Hepatocellular carcinoma (HCC) is an aggressive disease with high recurrence rate. However, current staging systems were lack of predictive capacity for HCC recurrence. We aimed to develop prognostic nomograms based on inflammation-related markers for HCC patients underwent hepatectomy. MATERIALS AND METHODS: We recruited 889 surgically treated patients from two medical centers. Independent prognostic factors were identified by cox regression analyses. Nomograms for recurrence-free survival (RFS) and overall survival (OS) were established, and validated internally and externally. The performance, discrimination, and calibration of nomograms were assessed, and compared with existed staging systems. RESULTS: Neutrophil to lymphocyte ratio (NLR) and gamma-glutamyl transpeptidase to platelet ratio (GPR) were the two inflammation-related factor that independently correlated with survival. NLR, GPR, international normalized ratio (INR), microvascular invasion, satellite lesions, tumour number, tumour diameter, and macrovascular invasion were used to construct nomogram for RFS while GPR, total bilirubin, INR, α-fetoprotein, microvascular invasion, satellite lesions, tumour diameter, and macrovascular invasion were for OS. In the training cohort, the C-index of nomogram was 0.701 (95% confidence interval [CI], 0.669 to 0.732) for RFS and 0.761 (95% CI, 0.728 to 0.795) for OS. These results received both internal and external validation with C-index of 0.701 (95% CI, 0.647 to 0.755) and 0.707 (95% CI, 0.657 to 0.756) for RFS, and 0.706 (95% CI, 0.640 to 0.772) and 0.708 (95% CI, 0.646 to 0.771) for OS, respectively. The nomograms showed superior accuracy to conventional staging systems (p<0.001). CONCLUSION: The nomograms based on inflammation-related markers are of high efficacy in predicting survival of HCC patients after hepatectomy, which will be valuable in guiding postoperative interventions and follow-ups.

We present a case of spontaneous rupture of hepatocellular carcinoma with poor liver function managed by transcatheter arterial embolization (TAE). The patient's bilirubin level was 2.1 mg/dL, albumin level was 2.4 g/dL, and prothrombin time international normalized ratio was 2.1. In addition, the patient had also developed a large number of ascites. The tumor was supplied by the right renal capsular artery, as observed on angiography. With successful TAE, no hepatic failure occurred. We believe TAE can be a safe and effective treatment option, even in patients with poor liver function, if tumors are supplied only by extrahepatic collateral vessels.

BACKGROUND AND OBJECTIVES: There are limited data on the use of non-vitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) patients with cancer. We aimed to assess the efficacy and safety of NOACs in AF patients with cancer in this study. METHODS: In 2,568 consecutive non-valvular AF patients with newly diagnosed cancer, we analyzed ischemic stroke/systemic embolism (SE), major bleeding, and all-cause death. Based on propensity score matching, 388 matched pairs were included in the NOAC and warfarin groups. RESULTS: Patient baseline characteristics were comparable between the matched groups. During median follow-up of 1.8 years, the NOAC group had significantly lower incidences of ischemic stroke/SE (p < 0.001), major bleeding (p < 0.001), and all-cause death (p < 0.001) than the warfarin group. Moreover, the incidence of major bleeding was significantly lower in the NOAC group than in the warfarin group with optimal international normalized ratio control (p=0.03). Especially, within 1 year after cancer diagnosis, the incidences of all clinical events were significantly lower in the NOAC group than in the warfarin group. CONCLUSIONS: In AF patients with newly diagnosed cancer, NOACs showed lower incidences of ischemic stroke/SE, major bleeding, and all-cause death than warfarin, especially within 1 year after cancer diagnosis.

BACKGROUND: The Coapresta 2000 (CP2000; Seikisui, Japan) system is a fully-automated random-access multiparameter coagulation analyzer equipped with a photo-optical clot detection unit. It can perform clotting time assays as well as colorimetric assays. METHODS: We evaluated the analytical performance of CP2000 for several coagulation test parameters and compared its performance with that of the CA-7000 (Sysmex, Japan) system. Fresh and frozen plasma samples were used to evaluate the performance of CP2000 with respect to four routine coagulation test parameters: prothrombin time (PT), activated partial thromboplastin time, fibrinogen, and D-dimer. On-board stability of the liquid reagents was confirmed. Additionally, local international sensitivity index (ISI) verification was performed with four levels of calibrants and direct PT/international normalized ratio (INR) line. RESULTS: The intra- and inter-assay coefficients of variation were below 5% for every parameter in both normal and pathological ranges. Carryover was not detected. The results obtained using CP2000 showed good correlation (r 2 over 0.95) with those obtained by the CA-7000 analyzer. On-board stability in open-vial state, which was expected to be much longer than that of other reagents, was confirmed. Local verification of ISI showed an acceptable bias range of INR, compared with the values using calibrants. CONCLUSIONS: The high-throughput, CP2000 analyzer is a fast, user-friendly system with long on-board reagent stability. Its results were concordant with the CA-7000 analyzer, for analysis of the routine coagulation test parameters. Furthermore, this system would add greater confidence to the reporting of INR data.
