Abstract
BACKGROUND AND AIM In most patients with perihilar cholangiocarcinoma (PHCC), major hepatectomy and extrahepatic bile duct resection are needed for surgical radicality, and a high risk of hepatic insufficiency exists. This study aims to develop a prediction model for post-hepatectomy liver failure (PHLF) in patients with PHCC. METHODS A total of 143 patients who underwent major liver resection and extrahepatic bile duct resection for PHCC between October 2001 and December 2013 were included. Clinically relevant PHLF was defined as liver failure corresponding to grade B or C of the International Study Group of Liver Surgery criteria. Multivariate logistic regression was used to develop the PHLF risk model. Model performance was evaluated internally using the area under the curve analysis (discrimination) after 1000 bootstrap resampling and the Hosmer-Lemeshow goodness-of-fit test (calibration). RESULTS Post-hepatectomy liver failure occurred in 43.4% of patients (n = 62). In multivariate analysis, PHLF was significantly associated with future liver remnant ratio (odds ratio [OR] per 10% = 0.68, 95% confidence interval [CI] 0.51-0.88), intraoperative blood loss (OR per 1 L = 1.82, 95% CI 1.11-3.17), and preoperative prothrombin time > 1.20 (OR = 3.22, 95% CI 1.15-9.97). The PHLF risk score model showed good discrimination (area under the curve = 0.708, 95% CI 0.623-0.793) and calibration (P = 0.227). CONCLUSIONS The risk model proposed in this study accurately predicted PHLF in patients with PHCC. This offers surgeons a practical guide to quantitative risk assessment of hepatic insufficiency and aids decision-making in surgical treatment and perioperative management.

Abstract
OBJECTIVE This study aimed to investigate whether clinical parameters and serum neuron-specific enolase (NSE) levels measured at emergency department (ED) presentation help stratify the risk of acute or delayed persistent severe neurological sequelae after acute carbon monoxide (CO) poisoning induced by charcoal burning. METHODS This retrospective study included 236 patients who suffered from CO poisoning. Demographic information, serum NSE levels measured in the ED, treatment, clinical course, and long-term neurological outcomes were recorded. RESULTS The median serum NSE level at presentation was 15.5 (10.9-22.7) ng/mL. No differences were observed in the duration of CO exposure; the initial Glasgow Coma Scale (GCS) score; the levels of arterial HCO3-, white blood cells (WBCs), C-reactive protein (CRP) or troponin I; or the frequency of abnormal diffusion-weighted imaging finding at presentation among the groups with different serum NSE levels at presentation. The incidences of acute and delayed persistent neurologic sequelae assessed at 22.3 months after acute charcoal CO poisoning were 5.1% and 8.5%, respectively. No difference in the NSE level was observed between patients stratified according to long-term neurological status. According to the multinomial logistic regression analysis, age, serum CRP levels and the initial GCS score were risk factors for the two types of persistent severe neurological sequelae, whereas troponin I levels were associated only with the acute persistent severe neurological sequelae. However, the adjusted NSE level was not a risk factor for any persistent neurological sequelae. CONCLUSIONS Serum NSE levels at presentation were not correlated with the risk of acute or delayed persistent neurological sequelae. Further studies with blood sampling at optimal time points and serial measurements should be conducted. Age, initial GCS score, and CRP levels may be risk factors for persistent severe neurological sequelae.

Abstract
We designed the study to clarify the prognostic significance of perioperative (preoperative, intraoperative, and postoperative) red blood cell (RBC) transfusion following pancreaticoduodenectomy (PD) for periampullary cancers.This study retrospectively analyzed 244 periampullary cancer patients (pancreatic cancer, 124 patients; bile duct cancer, 63 patients; and ampullary cancer, 57 patients) treated by PD from June 2001 to June 2010 at the National Cancer Center, Korea (NCC2017-0106).A total of 112 (46%) of 244 patients had received transfusion (preoperative, 5%; intraoperative, 17%; and postoperative, 37%). The 5-year survival rate of patients without perioperative transfusion was 36%, whereas that of patients with a transfusion was 25% (P = .04). Perioperative transfusion and intraoperative transfusion were found to be independent poor prognostic factors [relative risk (RR): 1.52 and 1.95, respectively]. The independent factors associated with perioperative transfusion were being female, operation time >420 minutes, portal vein (PV) resection, and preoperative serum hemoglobin (Hb) < 12 mg/dL. As the amount of perioperative transfusion increased, overall survival (OS) decreased.Perioperative transfusion, especially intraoperative transfusion was an independent prognostic factor for survival after PD. Therefore, for patients with periampullary cancer, intraoperative bleeding and operation time should be minimized and preoperative anemia corrected.

Abstract
Purpose Even though the therapeutic gold standard of hilar cholangiocarcinoma (HCCA) resection is cancer-free resection margin (RM), surgical treatment still remains challenging. This study evaluated the prognostic significance of RM status in resected HCCA patients and identified survival prognostic factors. Materials and Methods We reviewed records of 96 HCCA patients who underwent surgery from 2001 to 2012 and analyzed the RM status and prognostic factors that affecting survival. Results Negative RM (n=31, 33%) was significantly associated with better survival vs. positive RM (n=65, 67%) (mean survival time [MST], 33 months vs. 21 months; p=0.011). Margins with histological findings of non-dysplastic epithelium, low-grade dysplasia, and carcinoma in situ were not associated with survival differences (MST, 33 months vs. 33 months vs. 30 months; p=0.452), whereas positive margins were associated with poorer survival relative to carcinoma in situ (MST, 30 months vs. 21 months; p=0.050). Among patients with R0 resection, narrow (≤ 5 mm) and wide (> 5 mm) margins were not associated with survival differences (MST, 33 months vs. 30 months; p=0.234). Although positive proximal RM was associated with poorer survival compared to negative RM (MST, 19 vs. 33; p=0.002), no survival difference was observed between positive and negative distal RMs (MST, 30 vs. 33; p=0.628). Proximal RM positivity (hazard ratio [HR], 2.688; p=0.007) and nodal involvement (HR, 3.293; p < 0.001) were independent survival prognostic factors. Conclusion A clear RM, especially proximal RM status, was significant prognosticator, and proximal bile duct resection to the greatest technically feasible extent may be necessary, with careful consideration of the potential morbidity and oncologic outcomes after resection. However, an aggressive approach to obtain a negative distal RM might be controversial and should be considered carefully, depending on the patient's status.

Abstract
PURPOSE This study investigated the predictive factors for progression from seizure-related endosulfan poisoning to status epilepticus (SE) and refractory SE (RSE). This study also investigated delayed neurologic sequelae in seizure-related endosulfan poisoning. METHODS This retrospective, observational case series consisted of 73 patients who developed at least one seizure after endosulfan ingestion. RESULTS The progression rates from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE were 78.1% and 54.4%, respectively. The SE and RSE fatality rates were 19.2% and 41.9%, respectively. No patients reported the development of delayed neurological sequelae at least six months after discharge. Glasgow coma scale (GCS) score were identified as an independent factor for progression from seizure-related endosulfan poisoning to SE and from SE-related endosulfan poisoning to RSE. Lorazepam administration was independently associated with preventing progression from SE-related endosulfan poisoning to RSE. CONCLUSION Seizure-related endosulfan poisoning had higher progression rates to SE and RSE and higher fatality rates than other drug-induced seizures. However, delayed neurologic sequelae after discharge were not demonstrated. Due to the high progression rates from seizure-related endosulfan poisoning to SE and RSE and the absence of an established treatment for SE-related endosulfan poisoning, physicians should aggressively treat patients who experience a seizure after endosulfan poisoning and who present with decreased GCS score. Lorazepam should be considered a first-line anti-epileptic drug for controlling seizures in patients with endosulfan poisoning.

Abstract
The new biomarkers are essential for improving the survival and prognosis of hepatocellular carcinoma(HCC) patients. Alpha-fetoprotein(AFP) is the most widely used biomarker. But the low sensitivity and specificity limits its clinical application. Recent study validated the diagnostic capability of osteopontin(OPN) and dickkopf-1(DKK1) and assessed the combination of AFP, DKK1, and OPN as a panel for the diagnosis of HCC. Based on these previous studies, we hypothesized that combination of OPN and DKK1 can be used to as a marker for prognosis to patient of HCC after hepatectomy. From January 2006 to December 2008, patients undergoing hepatectomy for hepatocellular carcinoma were screened serum that has been stored in the Bank of tumor. To target the selected patient, it was confirmed that the remaining tissue specimen is stored after diagnosis. Serum of the patients was used to investigate the OPN and DKK1 by ELISA. In the paraffin block were prepared unstained slide and OPN and DKK1 level checked by IHC. It examined the correlation between prognosis and biomarkers through statistical analysis. AFP, OPN(serum level) and DKK1(serum level) are an independent prognostic factor for overall survival(OS) in HCC after hepatectomy(n=60, P=0.0204, 0.0167 and 0.0455 respectively). New biomarkers combinations based on the AFP existing biomarker are showed a falling curve of the overall survival(OS) and disease-free survival(DFS) in Kaplan Meier curve. In conclusion, combination of OPN, DKK1 and AFP as a biomarker could support the correct diagnosis for HCC after hepatectomy.

Abstract
BACKGROUND AND AIM The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients. METHODS This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013. Prognostic factors were investigated by univariate and multivariate analysis, using the Cox's proportional hazards model. RESULTS The overall incidence of postoperative complications was 16.1% (n = 161), with an in-hospital mortality rate of 0.3% (n = 3). The rates of 1-, 3-, and 5-year overall survival were 91.9%, 78.9%, and 69.5%, while the rates of 1-, 3-, and 5-year recurrence-free survival were 71.7%, 51.7%, and 43.7%, respectively. Multivariate analysis showed that patient age, platelet count, intraoperative estimated blood loss (EBL), tumor number, Edmond-Steiner grade, microvascular invasion, major vessel invasion, and intrahepatic metastasis were independent significant prognostic factors affecting the overall survival. Platelet count, intraoperative EBL, maximal tumor size, major vessel invasion, capsule formation, intrahepatic metastasis, cirrhosis, and the pathological stage were independent prognostic factors for recurrence-free survival. CONCLUSIONS Survival of patients with HCC after resection should be stratified by various perioperative clinicopathological factors. Platelet count and intraoperative EBL could be considered as one of the powerful predictors of the prognosis and recurrence of HCC in such patients.

Abstract
The importance of bile duct division cannot be overemphasized in living donor surgery. Ligation and cut (LC) as a method for bile duct division in living donor right hepatectomy (LDRH) has never been reported. The purpose of this study was to introduce the LC method of bile duct division in LDRH. All LDRH donors were identified through a prospectively maintained database at the authors' institution between September 2009 and March 2013, and the 2 methods, LC and cut and oversewing (CO), were compared both in terms of donor and recipient outcomes of right lobe living donor liver transplantation. In the LC method, after complete parenchymal transection, the right hepatic duct was dissected in the Glisson's sheath and ligated just at the right side of the confluence, and then the right side of the ligature was cut. The LC and CO methods were performed in 109 and 134 donors, respectively. Bile duct division time (P < 0.001) and operative time (P < 0.001) were significantly shorter in the LC group than in the CO group. With a median follow-up of 60.2 months, biliary complication rate was lower in the LC group than in the CO group (0% versus 5.2%; P = 0.01), but with no significant difference between the recipient groups. All donors made a complete recovery. In conclusion, the bile ducts of living donors can be dissected safely from the Glisson's sheath, and the LC method facilitates bile duct division and has a lower incidence of biliary complication in LDRH without compromising the recipient outcomes.

Abstract
Portal vein embolization (PVE) is increasingly performed worldwide to reduce the possibility of liver failure after extended hepatectomy, by inducing future liver remnant (FLR) hypertrophy and atrophy of the liver planned for resection. The procedure is known to be very safe and to have few procedure-related complications.In this study, we described 2 elderly patients with Bismuth-Corlette type IV Klatskin tumor who underwent right trisectional PVE involving the embolization of the right portal vein, the left medial sectional portal branch, and caudate portal vein. Within 1 week after PVE, patients went into sepsis combined with bile leak and died within 1 month.Sepsis can cause acute liver failure in patients with chronic liver disease. In this study, the common patient characteristics other than sepsis, that is, trisectional PVE; chronic alcoholism; aged >65 years; heart-related comorbidity; and elevated serum total bilirubin (TB) level (7.0 mg/dL) at the time of the PVE procedure in 1 patient, and concurrent biliary procedure, that is, percutaneous transhepatic biliary drainage in the other patient might have affected the outcomes of PVE.These cases highlight that PVE is not a safe procedure. Care should be taken to minimize the occurrence of infectious events because sepsis following PVE can cause acute liver failure. Additionally, prior to performing PVE, the extent of PVE, chronic alcohol consumption, age, comorbidity, long-lasting jaundice, concurrent biliary procedure, etc. should be considered for patient safety.

Abstract
BACKGROUND Few studies have evaluated the impact of previous abdominal surgery (PAS) on living donor right hepatectomy (LDRH). The aim of this study was to investigate the outcomes of liver transplantation using right lobe grafts of living donors with PAS. METHODS Data were reviewed from LDRH patients at the authors' institution between March 2008 and November 2014. LDRH patients with PAS were divided into two groups according to upper PAS (group 1) or lower PAS (group 2), and they were compared to those without PAS (group 3) who were matched 1:1 based on age, gender, and body mass index. Perioperative data, complications by the Clavien classification, and the outcomes with more than 14 months follow-up were compared. RESULTS Twenty-three (4.9%) of a total of 471 LDRH donors had PAS. Eleven donors were assigned to group 1, 12 to group 2, and 23 to group 3. Intraperitoneal adhesions were found in 20 (87.0%) of 23 donors with PAS, of whom 5 (21.7%) had adhesiolysis-related injuries that happened more commonly in group 1 than in group 2 (P=0.025). LDRH was successfully completed under upper midline laparotomy in all donors. No donors received perioperative blood transfusion. The peak postoperative AST, ALT, INR, and total bilirubin levels made no difference between the three groups. Compared with group 3, groups 1 and 2 had a longer operative time (P=0.012) and a higher grade I complication rate (P=0.047). All donors recovered fully to their routine activities. The 23 recipients of grafts from donors with PAS showed good liver function with 1-year graft and patient survivals of 100%. CONCLUSION A history of PAS is not a contraindication to LDRH in the current era of advanced surgical techniques.

Abstract
Abstract
Background
Skin antiseptic agents are used to prevent surgical-site infection (SSI); few trials have reported the superiority of any specific agent in clean-contaminated abdominal surgery. This RCT was designed to compare the effectiveness of chlorhexidine gluconate and povidone–iodine.
Methods
Consecutive patients who underwent clean-contaminated upper gastrointestinal or hepatobiliary–pancreatic open surgery between 2011 and 2014 were assigned randomly to either chlorhexidine gluconate or povidone–iodine. The primary endpoint was the occurrence of SSI within 30 days of surgery. Secondary endpoints included causative organisms and risk factors for SSI.
Results
A total of 534 patients were randomized; 31 (5·8 per cent) developed an SSI. There was no difference in the overall SSI rate in the chlorhexidine gluconate and povidone–iodine groups: 15 of 267 (5·6 per cent) and 16 of 267 (6·0 per cent) respectively (P = 0·853). The most common causative organism was Enterococcus faecalis. In subgroup analysis, biliary–pancreatic surgery had a higher SSI rate (26 of 127, 20·5 per cent) than upper gastrointestinal (2 of 204, 1·0 per cent) and hepatic (3 of 203, 1·5 per cent) resection. Both age (60 years and over) and type of incision were associated with the risk of SSI.
Conclusion
No difference was detected between chlorhexidine gluconate and povidone–iodine antiseptics for prevention of SSI. Registration number: NCT01495117 (http://www.clinicaltrials.gov).

Abstract
Living donor liver transplantation (LDLT) becomes an important option for treatment for patients with hepatocellular carcinoma (HCC). With the advance of imaging modalities such as computed tomography (CT) and magnetic resonance image (MRI), preoperative staging and diagnosis for HCC was improved in LDLT. However, morphological characteristics based on the tumor number and size do not represent the tumor pathology and prognosis clearly. Therefore, many criteria using various markers have been reported, but still have limitation to predict the pathology and prognosis. Recently, 18F-fluorodeoxyglucose-positron emission tomography/CT (18F-FDG PET/CT) was introduced to have the usefulness for detection of extrahepatic metastases and prediction of post-transplant prognosis in liver transplantation (LT). Furthermore, the hybrid concept with both biologic activity using PET/CT and morphologic tumor characteristics using CT and MRI was reported to be selection criteria for the patient with HCC waiting LDLT. We will discuss the role of 18F-FDG PET/CT in LDLT as various aspects including tumor detection, pathology prediction, prognosis prediction, and possibility of selecting criteria.

We describe 2 cases of patients with loss of hepatic arterial flow during surgery for pancreatic head cancer due to celiac stenosis caused by median arcuate ligament compression. The first case underwent pylorus-resecting pancreatoduodenectomy for pancreatic head cancer. After resection of the gastroduodenal artery, flow in the common hepatic artery disappeared, and celiac axis stenosis was identified. Interventional stent insertion was attempted, however, it failed due to the acute angle of the celiac orifice (os). This problem was resolved by arterial reconstruction. The second case underwent pylorus-preserving pancreatoduodenectomy for pancreatic head cancer and the same phenomenon occurred during the procedure. Interventional stent insertion was also tried; in this patient, however, it failed due to the acute angle of the celiac os. The problem was resolved by changing a femoral approach to a brachial approach, and the stent was inserted into the celiac os successfully.

Abstract
Chronic obstructive lung disease (COPD) primarily affects men; however, its epidemiology has been changing because more women have become smokers. Recently, investigators found that although women and men were exposed to the same amount of smoke fume, women tended to have more severe disease and higher mortality rate. They also complain of more dyspnoea and may experience more severe exacerbations than men. This led to the question of whether sex has an impact on COPD course and whether women have a higher susceptibility to smoke fumes than men. That may be explained by multiple complex factors highlighting the relationship between sex, epidemiology, method of diagnostics and the clinical course of the disease. In this review, sex differences in epidemiology, clinical presentation, exacerbation, co-morbidities and treatment are covered.

Proposal of new expanded selection criteria using total tumor size and 18F-fluorodeoxyglucose - positron emission tomography/computed tomography for living donor liver transplantation in patients with hepatocellular carcinoma: The National Cancer Center Korea criteria. World J Transplant 2016; 6:411-422.

Abstract
AIM: To expand the living donor liver transplantation (LT) pool of eligible patients with hepatocellular carcinoma (HCC) using new morphological and biological criteria.
METHODS: Patients with HCC who underwent living donor LT (LDLT) from March 2005 to May 2013 at the National Cancer Center Korea (NCCK) were enrolled. We performed the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) before LDLT. Overall and disease-free survival analysis was done in patients to evaluate the usefulness of new NCCK criteria using PET/CT and total tumor size (10 cm).
RESULTS: We enrolled a total of 280 patients who pathologically confirmed to have HCC and performed the PET/CT before transplantation. Among them, 164 (58.6%) patients fulfilled the NCCK criteria and 132 patients (47.1%) met the Milan criteria. Five-year overall and disease-free survival rates for patients who fulfilled the NCCK criteria showed 85.2% and 84.0%, respectively, and were significantly higher than those beyond the NCCK criteria (60.2% and 44.4%, respectively; P < 0.001). The correlation analysis between preoperative imaging tests and pathologic reports using Cohen’s Kappa demonstrated the better results in the NCCK criteria than those in the Milan criteria (0.850 vs 0.583). The comparison of disease-free analysis among the NCCK, Milan, and University of California, San Francisco (UCSF) criteria using the receiver operating characteristics curves revealed the similar area under the curve value criteria (NCCK vs Milan, P = 0.484; NCCK vs UCSF, P = 0.189 at 5-years).
CONCLUSION: The NCCK criteria using hybrid concept of both morphological and biological parameters showed an excellent agreement between preoperative imaging and pathological results, and favorable survival outcomes. These new criteria might select the optimal patients with HCC waiting LDLT and expand the selection pool.

Abstract
The impact of intra-abdominal adhesion (IAA) on living donor right hepatectomy (LDRH) remains to be clarified. The purpose of this study was to compare both the donor and recipient outcomes of right lobe living donor liver transplantation according to IAA detected intraoperatively. LDRH donors were identified through a prospectively maintained database at the authors' institution between March 2008 and February 2014. IAA was graded according to Beck et al (Dis Colon Rectum 2000; 43: 1749-1753). LDRH donors with IAA (group A) were matched 1:3 to those without IAA (group B) based on age, gender, and BMI. Perioperative data, complications by the Clavien classification, and the outcomes with at least 12 months follow-up were compared. Thirty-two (7.6%) of a total of 420 LDRH donors had IAA around the liver. Nineteen donors had previous abdominal surgery. LDRH was successfully completed under upper midline laparotomy in all donors. Compared with group B, group A had a longer operative time (270 vs. 172 min; p < 0.001), a higher wound complication rate (28.1% vs. 4.2%; p = 0.009), and a longer postoperative stay (10 vs. 7 days; p = 0.009). All donors recovered completely to their previous activities. The 1-year graft and recipient survivals of recipients were comparable between two groups. These findings support the feasibility and safety of LDRH in patients with IAA.

Abstract
AIM: To investigate the impact of high-dose hepatitis B immunoglobulin (HBIG) on hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) recurrence and overall survival after living donor liver transplantation (LDLT).
METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen (HBeAg) -positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose.
RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively (P = 0.042). In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose (P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met (P = 0.317 and 0.190, respectively) and did not meet (P = 0.350 and 0.987, respectively) the Milan criteria.
CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBeAg-positive patients after LDLT.

Abstract
The concept of surgery for enhanced recovery (SFER) program has never been an issue in the context of living donor right hepatectomy (LDRH), much less its effects. The purpose of this study was to evaluate outcomes after the establishment of an SFER protocol for LDRH in a single center.A single-center cohort study was performed in 500 consecutive living donors who underwent right hepatectomy from January 2005 to June 2014 by analyzing the outcomes before and after an established SFER protocol that evolved with continuous refinements in surgical technique and management over 300 LDRHs, being in place on September 2011. Donor characteristics, operative outcomes, and postoperative complications divided into 2 groups (group 1, stepwise adjustment; group 2, complete adherence to the protocol) were compared.Donor characteristics were comparable in the 2 groups. Overall complication rate was 10.0% with no mortality. In group 2, operative time, hospital stay, and overall complication rate decreased significantly, and the morbidity was 1% and confined in grade I complication without reoperation, perioperative blood transfusion, or readmission. All donors in this series recovered fully and returned to the previous functional lifestyle.An SFER protocol on LDRH can be established by the gradual implementation of various refinements of surgical technique, and the recent outcomes achieved after the establishment of an SFER protocol could provide a current guidance on LDRH toward the ultimate goal of zero morbidity.

Abstract
BACKGROUND Many patients with active Crohn's disease do not adequately respond to therapies, highlighting the need for new treatments. AIMS To conduct a randomised, double-blind, placebo-controlled phase 3 study to assess the efficacy and safety of vercirnon, an oral inhibitor of CC chemokine receptor-9, for the treatment of patients with moderately-to-severely active Crohn's disease. METHODS Patients with a Crohn's Disease Activity Index (CDAI) of 220-450, plus evidence of active disease (endoscopically confirmed or elevation of both C-reactive protein and faecal calprotectin), who had failed corticosteroid or immunosuppressant therapy were enrolled. Patients were equally randomised to receive placebo, vercirnon 500 mg once daily or vercirnon 500 mg twice daily. The primary endpoint was clinical response, defined as a 100-point decrease in CDAI from baseline to week 12. RESULTS Six hundred and eight patients were randomised. Patient characteristics and baseline demographics were similar among the groups. The proportions of patients achieving a clinical response were 25.1%, 27.6% and 27.2% for placebo, once daily and twice daily respectively; treatment differences were not significant (2.5%; 95% confidence interval, CI -6.1% to 11.0%, P = 0.546 for once daily vs. placebo, and 2.1%; 95% CI -6.5% to 10.7%, P = 0.648 for twice daily vs. placebo). Adverse events were reported in 69.8%, 73.3% and 78.1% with serious adverse events in 8.9%, 5.9%, and 6.0% of patients in the placebo, once-daily and twice-daily groups, respectively. CONCLUSIONS We did not demonstrate efficacy of vercirnon as an induction therapy in patients with moderately-to-severely active Crohn's disease; its effect in maintenance therapy was not addressed.

Abstract
BACKGROUND Clinical factors were previously identified as predictors of short-term treatment efficacy in Crohn's disease (CD). The PRECiSE 3 (P3) 7-year trial provides an opportunity to study predictors of short- and long-term clinical remission among CD patients treated with certolizumab pegol (CZP). AIM To identify factors that influence long-term remission of CD with CZP treatment. METHODS Patients who had completed placebo-controlled studies (PRECiSE 1/PRECiSE 2, P1/P2) enrolled in P3 and received open-label CZP 400 mg every 4 weeks up to 7 years. Baseline predictors included, but were not limited to, smoking status, disease duration, prior inflammatory bowel disease (IBD) surgery, Harvey-Bradshaw Index (HBI), albumin, haematocrit and CZP exposure; association with time to initial remission (HBI ≤4) was tested for patients who received CZP in P1/P2; time to loss of remission/frequency of maintenance of remission was also tested. Univariate analyses and multivariate Cox or logistic regression models were used. RESULTS Predictors for initial remission (N = 377) included age, haematocrit, prior IBD surgery and entry HBI (P < 0.05 for all). Predictors for loss of remission (N = 437) included HBI, serum albumin concentration, haematocrit, smoking status and exposure. Predictors of maintenance of remission (N = 437) included haematocrit, IBD surgery, HBI, disease duration, serum albumin concentration and exposure. Significant predictors were confirmed with stepwise multivariate regression models. CONCLUSIONS These analyses identified several influential parameters for short-and long-term remission of Crohn's disease with certolizumab pegol treatment. The data yield valuable hypotheses regarding factors that influence certolizumab pegol treatment. More investigation is needed. (ClinicalTrials.gov identifier NCT00552058).

Abstract
BACKGROUND Leukocyte subsets in peripheral blood, which include neutrophils, lymphocytes, and monocytes, have not been well established as prognostic factors in patients with hepatocellular carcinoma (HCC). METHODS Consecutive patients who underwent curative hepatic resection for HCC at the National Cancer Center, Republic of Korea, from 2001 to 2008 were enrolled in this retrospective study. Clinicopathologic factors, cancer-specific survival (CSS), and disease-free survival (DFS) were analyzed with respect to preoperative lymphocyte subsets, especially monocyte ratio. RESULTS The 603 patients had a median follow-up of 40.0 months and a 5-year overall survival rate of 67.7 %. In univariate analysis of survivals, preoperative lymphocyte ratio ≤35 % and monocyte ratio >7 % were significantly poor prognostic factors. In multivariate analysis, preoperative monocyte ratio >7 %, satellite nodule, and microvascular invasion were independent risk factors for CSS and DFS (hazard ratio of monocyte ratio >7 % = 1.77, p = 0.02 and 1.57, p = 0.006, respectively). Considering monocyte ratio with preoperative α-fetoprotein level, patients with both abnormal α-fetoprotein levels (>12 ng/mL) and monocyte ratio >7 % showed significantly worse CSS and DFS than other groups (p < 0.001). Cirrhotic patients with monocyte ratio >7 % showed significantly poor CSS and DFS compared with non-cirrhotic patients (p = 0.033 and <0.001, respectively). CONCLUSIONS A preoperative monocyte ratio >7 % of peripheral blood is an independent risk factor for CSS and DFS after hepatic resection for HCC. Preoperative monocyte ratio might be considered as a novel biomarker for HCC.
