Abstract
BACKGROUND Liver transplant (LT) is the standard therapy for end-stage liver disease. Advances in surgical techniques and immunosuppression protocols improved the results of LT by increasing long-term survival. Nevertheless, an adequate match between the donor and recipient is paramount for avoiding futile liver transplants. We aimed to identify the prognostic factors in donor-recipient LT matching. METHODS Retrospective analysis of adult LT was conducted from January 2006 to December 2018, which included the following transplant modalities: deceased donor LT (DDLT), living donor LT (LDLT), combined liver-kidney transplant (CLKT), and domino LT (DLT). RESULTS Among 1101 patients who underwent LT, 958 patients underwent DDLT, 92 patients underwent LDLT, 45 patients underwent CLKT, and 6 patients underwent DLT. The overall survival (OS) in 1, 5, and 10 years were 89%, 83%, and 82%, respectively. For DDLT, OS in 1, 5, and 10 years were 91%, 84%, and 82%, respectively. For LDLT, OS in 1, 5, and 10 years were 89%, 72%, and 69%, respectively. For CKLT, OS in 1, 5, and 10 years were 90%, 71%, and 71%, respectively. None of the DLT patients died. For DDLT, the factors that affected OS were the presence of fulminant liver failure (odds ratio [OR], 2.23; 95% CI, 1.18-4.18; P = .001), hemodialysis before LT (OR, 2.12; 95% CI, 1.27-3.5; P = .004), retransplant (OR, 4.74; 95% CI, 2.75-8.17; P = .000), and recipient age >60 years (OR, 1.86; 95% CI, 1.27-2.73; P = .001). For hospitalization before LT (due to an acute-on-chronic liver failure), the OR was 2.10 (95% CI, 1.29-3.42; P = .003). Donor intensive care unit time >7 days (OR, 1.46; 95% CI, 1.04-2.06; P = .02) was also associated with overall mortality. CONCLUSIONS We identified prognostic factors in donor-recipient LT matching. Furthermore, we demonstrated that an adequate organ allocation with donor-recipient selection might increase graft survival and reduce waiting list mortality.

Abstract
Background
Setting up new liver transplant (LT) centers is essential for countries with organ shortages. However, good outcomes require experience, because LT learning depends on a high number of surgeries. This study aims to describe how a new center was set up from a partnership between the new center and an experienced one. The step-by-step preparation process, the time needed and the results of the new center are depicted.
Material and methods
The mentoring process lasted 40 months, in which half of the 52 patients included on the transplant list received LT. After the mentorship, a 22-month period was also analyzed, in which 46 new patients were added to the waiting list and nine were operated on.
Results
The 30-day survival rates during (92.3%) and after (66.7%) the partnership were similar to the other LT centers in the same region, as well as the rates of longer periods. The waiting time on the LT list, the characteristics of the donors and the ischemia times did not differ during or after the mentorship.
Conclusion
The partnership between universities is a suitable way to set up LT centers, achieving good results for the institutions and the patients involved.

Abstract
BACKGROUND Alcohol-associated liver disease is the leading cause of liver transplantation in the western world. For these patients we calculated life expectancies both at time of transplant and several years later, stratified by key risk factors, and determined if survival has improved in recent years. METHODS Data on 14 962 patients with alcohol-associated liver disease who underwent liver transplantation in the MELD era (2002-2018) from the United States Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods. RESULTS Demographic and past medical history factors related to survival were patient age, presence of diabetes or severe hepatic encephalopathy, and length of hospital stay. Survival improved over the study period, at roughly 3% per calendar year during the first 5 years posttransplant and 1% per year thereafter. CONCLUSIONS Life expectancy in transplanted patients with alcohol-associated liver disease was much reduced from normal, and varied according to age, medical risk factors, and functional status. Survival improved modestly over the study period. Information on patient longevity can be helpful in making treatment decisions.

Abstract
INTRODUCTION AND AIM The Balance of Risk (BAR) Score, a simple scoring system that combines six independent donor and recipient variables to predict outcome after liver transplantation (LT), was validated in a large U.S./European cohort of patients. This study aims to assess the performance of the BAR score to predict survival after liver transplantation and determine the factors associated with short and long-term survival in Latin-American patients. MATERIAL AND METHODS A retrospective cohort study was performed in 194 patients [112 (55.4%) males; mean age 52±14 years] who underwent 202 LT during the period 2003-2015. Demographic, clinical, pathological and surgical variables, as well as mortality and survival rates, were analyzed. The BAR score was investigated through a receiver operating characteristics (ROC) curve with the calculation of the area under the curve (AUC) to evaluate the predictive score power for 3-month, 1 and 5-year mortality in a matched donor-recipient cohort. Youden index was calculated to identify optimal cutoff points. RESULTS The AUC of BAR score in predicting 3-month, 1-year and 5-year mortality were 0.755 (CI95% 0.689-0.812), 0.702 (CI95% 0.634-0.764) and 0.610 (CI95% 0.539-0.678) respectively. The best cut-off point was a BAR score ≥15 points. In the multivariate analysis BAR score <15 was associated with higher survival rates at 3 months and 1 and 5-years. CONCLUSIONS BAR score <15 points is an independent predictor of better short and long-term survival in Latin-American patients undergoing LT. The BAR scoring system has an adequate diagnostic capacity allowing to predict 3 and 12-month mortality.

Abstract
BACKGROUND Intraoperative temporary portocaval shunt (TPCS) has been performed during liver transplant to improve hemodynamics and renal function as well as to decrease bleeding during hepatectomy. The aim of this study was to evaluate the impact of TPCS on liver transplant in a long-term single-center study. METHODS From January 2006 to December 2018, all deceased donor transplants were retrospectively evaluated. Patients were divided in 2 groups: group 1, including those in whom intraoperative TPCS was performed and group 2, including those without TPCS. We analyzed recipient characteristics, survival, mortality, and complication rates in the intraoperative and postoperative periods. RESULTS A total of 999 deceased donor liver transplants were studied, with 509 patients in group 1 and 490 in group 2. There were 156 cases (15.61%) of preoperative portal vein thrombosis in the whole series. Postoperative renal function (P = .029) as well as length of hospital and intensive care unit stay (P = .0001) were better in group 1. Surgery time and warm ischemia time was also shorter in group 1 (P = .0001). Complications with Clavien-Dindo score ≥ 3 were higher in group 2 (P = .006). Multivariate analysis showed important risk with fulminant hepatitis (odds ratio, 2.127; 95% CI, 1.408-3.213; P < .0001) and Model for End-Stage Liver Disease > 29 (odds ratio, 2.492; 95% CI, 1.862-3.336; P < .0001). Overall survival in group 1 at 1, 5, and 10 years were 78%, 70%, and 68%, respectively. In group 2, they were 70%, 60%, and 58%, respectively (P = .027). CONCLUSIONS Patients who underwent intraoperative TPCS presented better postoperative renal function, less intraoperative blending, shorter surgical and warm ischemia time, shorter length of hospital and intensive care unit stay, and better overall survival after transplant. Moreover, TPCS should be used patients with severe conditions, such as fulminant hepatitis and Model for End-Stage Liver Disease score > 29.

Abstract
BACKGROUND Living donor liver transplant (LDLT) is a well-established treatment for end-stage liver disease. A better recipient selection and hemodynamic evaluation may improve transplant outcomes. The aim of this study was to establish recipient parameters that could enhance the results of adult-to-adult LDLT. METHODS We performed a retrospective study of all adult-to-adult LDLTs from a single center between January 2006 and December 2018. Variables analyzed included demographic and clinical parameters, laboratory tests, performance of intraoperative temporary portocaval shunt (TPCS), graft weight/recipient weight ratio (GW/RW), preoperative portal vein thrombosis (PVT), previous major abdominal surgery, and patient survival. Patients were divided in 2 groups according to GW/RW (0.8% cutoff point). RESULTS A total of 92 adult-to-adult LDLTs were analyzed, encompassing 53 male patients (57.6%). Mean Model for End-Stage Liver Disease score was 13.97 (SD, 4.74), and 57 patients (61.95%) had Child-Pugh-Turcotte score B. Mean GW/RW was 1.1% (SD, 0.37%). Group 1 with GW/RW > 0.8% (n = 74) and group 2 with it ≤ 0.8% (n = 13) presented mean GW/RW of 1.14% (SD, 0.24%) and 0.69% (SD, 0.09%) and P < .01, respectively. Eighteen patients (19.56%) presented PVT, with a worse survival than those without PVT (P = .006). Sixteen patients (17.39%) with previous major abdominal or biliary operations also presented higher mortality (P = .341). Forty-six (50%) intraoperative TPCSs were performed with a better 1- and 3-year patient survival. Receiver operating characteristic curve analysis showed PVT area under the curve of 0.701 (95% CI, 0.526-0.876; P = .018), positive predictive value of 0.69, and negative predictive value of 0.62. Multivariate analysis showed important risk regarding PVT (odds ratio, 6.160; 95% CI, 1.566-24.223; P = .004) and retransplant (odds ratio, 4.452; 95% CI, 0.843-23.503; P = .06). CONCLUSIONS Better recipient selection without PVT or previous major abdominal surgery, an adequate GW/RW, and intraoperative TPCS with hemodynamic modulation significantly improve outcomes of adult-to-adult LDLT.

Abstract
BACKGROUND Currently, the diagnosis of acute on chronic liver failure (ACLF) is clinical, and its early identification and proper management are essential for a better prognosis. The aim of this study was to identify histopathologic parameters by analyzing cirrhotic liver explants that could aid in the early recognition of this entity and to determine prognostic factors that would influence ACLF management. METHOD We performed a retrospective analysis of histopathologic material from liver explants from patients transplanted because of chronic hepatitis C virus infection from January 2007 to July 2017. Twenty-nine (n = 29) cases without hepatocellular carcinoma were selected. Histopathologic analysis included the Laennec classification, vascularization, and portal vein thrombosis. RESULTS According to the diagnosis of ACLF, patients were divided in 2 groups: group ACLF (n = 10) and group no acute on chronic liver failure (NO-ACLF) (n = 19). Considering the whole series, mean age was 51 ± 11.48 years and prevalence of men was 58.62%. The mean Model of End-Stage Liver Disease (MELD) score at time of transplantation was significantly higher in the ACLF group than in the NO-ACLF group (35 ± 7 vs 22 ± 6, respectively, P < .05) as was the mean total bilirubin (14.38 ± 13.31 vs 8.84 ± 10.46 mg/dl, respectively, P < .05). Histopathologic analysis of explanted livers according to Laennec staging system of cirrhosis was as follows: 1. Group NO-ACLF: 1 case (5.25%) grade 3, 6 cases (31.58%) grade 4B, and 12 cases (63.16%) grade 4C; and 2. Group ACLF: 4 cases (40%) grade 4B and 6 cases (60%) grade 4C. Cholestasis was found in 1 patient in the NO-ACLF group (5%) and in 4 patients in the ACLF group (40%) (P = .03). We studied 30-day and 10-year survival respectively, which were 80% and 60% in the ACLF group and 83% and 70% in the NO-ACLF group (P = .794 and P = .657). CONCLUSION In this preliminary approach, clinical and histologic findings contributed to the differential diagnosis of ACLF. The mean MELD score at time of liver transplantations, total bilirubin levels, and histologically evident cholestasis were significantly higher in patients with ACLF than in those without ACLF.

Abstract
BACKGROUND Liver transplantation (LT) has evolved to improve graft and patient survival. Early graft dysfunction (EGD) and primary nonfunction are an important cause of morbi-mortality. We had formulated the scientific hypothesis that the liver function can be evaluated by the indocyanine green (IG) after LT. The aim was to evaluate the EGD by plasma disappearance rate (PDR) of IG after LT. METHOD Prospective and observational clinical study, from July 2014 to June 2015. IG evaluation by pulse densitometry, Limon system. Degree analysis of ischemia and reperfusion injury in groups as follows: 1 (G0/G1/G2) and 2 (G3/G4). Donor risk index (DRI), Wagener and Olthoff criteria, and prognostic predictors were evaluated. All tests were performed with bidirectional α of 0.05 and a confidence interval of 95% and support by IBM SPSS 25. RESULTS A total of 40 patients, mean age 53.3 ± 14.0 years and a majority of men and hepatitis C virus. PDR were more relevant with high degrees of ischemia and reperfusion injury grades G3/G4 (P = .030). The PDR related to the donor risk index showed positive significance at DRI >1.5 (P = .066). The retention rate of IG at 15 minutes demonstrated potential in assessing graft loss or death (P = .063). CONCLUSION EGD can be assessed by PDR with high degrees of ischemia and reperfusion injury (G3/G4) and with marginal donors (DRI >1.5). The retention rate of IG at 15 minutes demonstrated potential in assessing graft loss or death of the patient.
