Abstract
The effectiveness of liver transplantation to cure numerous diseases, alleviate suffering, and improve patient survival has led to an ever increasing demand. Improvements in preoperative management, surgical technique, and postoperative care have allowed increasingly complicated and high-risk patients to be safely transplanted. As a result, many patients are safely transplanted in the modern era that would have been considered untransplantable in times gone by. Despite this, more gains are possible as the science behind transplantation is increasingly understood. Normothermic machine perfusion of liver grafts builds on these gains further by increasing the safe use of grafts with suboptimal features, through objective assessment of both hepatocyte and cholangiocyte function. This technology can minimize cold ischemia, but prolong total preservation time, with particular benefits for suboptimal grafts and surgically challenging recipients. In addition to more physiological and favorable preservation conditions for grafts with risk factors for poor outcome, the extended preservation time benefits operative logistics by allowing a careful explant and complicated vascular reconstruction when presented with challenging surgical scenarios. This technology represents a significant advancement in graft preservation techniques and the transplant community must continue to incorporate this technology to ensure the benefits of liver transplant are maximized.

Abstract
The impact of aspartate transaminases (AST) and gamma-glutamyl transferase (GGT) in serum of deceased donors on outcomes after liver transplantation (LT) is unclear. This study aimed to explore the relationship between donor highest AST value or first donor GGT value and graft survival. All consecutive patients who underwent a primary LT in a single center with available donor AST (N=1253) and GGT value (N=1152) were included. There was no significant association between donor AST and 90-day graft survival. We found a moderate association between GGT and 90-day graft survival. We found a significant interaction with a donor history of alcohol abuse (HAA). The risk of graft loss was associated with AST and GGT in donors with an HAA but remains unchanged in donors without HAA. There was no difference in graft survival according to donor AST or GGT with a cutoff ≥ 95th percentile (475 UI/L for AST and 170 UI/L for GGT). However, graft survival was significantly decreased when donors combined GGT ≥ 170 UI/L and HAA (61% at one year). Hepatic grafts from donors with high AST or high GGT but without alcohol history and no additional risk factors can be transplanted in low-risk recipient.

Abstract
PURPOSE MRI proton density fat fraction (PDFF) can be calculated using magnitude (MRI-M) or complex (MRI-C) MRI data. The purpose of this study was to identify, assess, and compare the accuracy of common PDFF thresholds for MRI-M and MRI-C for assessing hepatic steatosis in patients with obesity, using histology as reference. METHODS This two-center prospective study included patients undergoing MRI-C- and MRI-M-PDFF estimations within 3 days before weight loss surgery. Liver biopsy was performed, and histology-determined steatosis grades were used as reference standard. Using receiver operating characteristics (ROC) analysis on data pooled from both methods, single common thresholds for diagnosing and differentiating none or mild (0-1) from moderate to severe steatosis (2-3) were selected as the ones achieving the highest sensitivity while providing at least 90% specificity. Selection methods were cross-validated. Performances were compared using McNemar's tests. RESULTS Of 81 included patients, 54 (67%) had steatosis. The common PDFF threshold for diagnosing steatosis was 5.4%, which provided a cross-validated 0.88 (95% CI 0.77-0.95) sensitivity and 0.92 (0.75-0.99) specificity for MRI-M and 0.87 sensitivity (0.75-0.94) with 0.81 (0.61-0.93) specificity for MRI-C. The common PDFF threshold to differentiate steatosis grades 0-1 from 2 to 3 was 14.7%, which provided cross-validated 0.86 (95% CI 0.59-0.98) sensitivity and 0.95 (0.87-0.99) specificity for MRI-M and 0.93 sensitivity (0.68-0.99) with 0.97(0.89-0.99) specificity for MRI-C. CONCLUSION If independently validated, diagnostic thresholds of 5.4% and 14.7% could be adopted for both techniques for detecting and differentiating none to mild from moderate to severe steatosis, respectively, with high diagnostic accuracy.

Abstract
BACKGROUND AND AIM Liver grafts from donors with chronic and active history of alcohol abuse are usually immediately ruled out for use in liver transplantation (LT). The aim of our study is to evaluate the use of those grafts. METHODS From 2011 to 2016, a study group (Group 1) composed of 5 adult LT patients transplanted with livers from donors with alcohol abuse, was compared with a control group (Group 2) of 10 randomly matched patients who received liver transplants. Preoperative, intraoperative, and postoperative data were compared. RESULTS Among donors, serum gamma-glutamyl transferase values were significantly higher in Group 1. In recipients, post-LT laboratory exams showed significantly higher peak values of aspartate transaminase and alanine transaminase in Group 1; higher values of aspartate aminotransferase, alanine aminotransferase, and total bilirubin in Group 1 were also recorded on day 0. Early allograft dysfunction occurred at higher rates in Group 1 (80% vs 20%, P = .025), with no differences in early rejection episodes or early surgical repeat interventions. All patients from both groups were alive after 20 ± 10 (range 6-35) months from LT. CONCLUSION Despite higher rates of early allograft dysfunction, selected liver grafts from donors with alcohol abuse can be accepted for LT with good clinical results.

Heavy Alcohol Use Among Deceased Donors Does Not Impact Recipient Outcomes After Liver Transplantation. Transplantation 2018; 102:1864-1869.

Abstract
BACKGROUND Data on liver transplant (LT) outcomes using deceased donors with heavy drinking (HD) (>2 drinks per day) are scanty. METHODS Using the United Network for Organ Sharing database (2002-2014), we examined outcomes after LT in adults comparing deceased HD donors with non-HD (ND) donors. RESULTS Of 56 182 first LTs performed in the United States for 10 common indications using deceased donors, 47 882 with available information on alcohol use were analyzed. Of these 47 882 LT recipients, 7298 (15%) were from HD donors, with similar proportion over time (2002-2014, Armitage trend test P = 0.75) and for recipient liver disease etiology (χ P = 0.42). Proportion of liver organ used for LT was lower for HD donors compared with ND donors (63% vs 78%; P < 0.001). Five-year outcomes on first LT comparing 7166 HD donors and 21 498 ND donors matched based on propensity score were similar for liver graft (73.7% vs 73.7%, log rank P = 0.98) and patient survival (77.6% vs 77.0%, P = 0.36). On Cox regression analysis, history of HD in deceased donors did not affect liver graft 1.02 (0.97-1.08) or patient survival 1.03 (0.97-1.09). CONCLUSIONS Among LT recipients using select liver grafts, history of HD in deceased donors does not impact outcomes after LT.

Abstract
The definition and factors of extended criteria donors have already been set; however, details of the various opinions still differ in many respects. In this review, we summarize the impact of these factors and their clinical relevance. Elderly livers must not be allocated for hepatitis C virus (HCV) positives, or patients with acute liver failure. In cases of markedly increased serum transaminases, donor hemodynamics is an essential consideration. A prolonged hypotension of the donor does not always lead to an increase in post-transplantation graft loss if post-OLT care is proper. Hypernatremia of less than 160 mEq/L is not an absolute contraindication to accept a liver graft per se. The presence of steatosis is an independent and determinant risk factor for the outcome. The gold standard of the diagnosis is the biopsy. This is recommended in all doubtful cases. The use of HCV+ grafts for HCV+ recipients is comparable in outcome. The leading risk factor for HCV recurrence is the actual RNA positivity of the donor. The presence of a proper anti-HBs level seems to protect from de novo HBV infection. A favourable outcome can be expected if a donation after cardiac death liver is transplanted in a favourable condition, meaning, a warm ischemia time < 30 minutes, cold ischemia time < 8-10 hours, and donor age 50-60 years. The pathway of organ quality assessment is to obtain the most relevant information (e.g. biopsy), consider the co-existing donor risk factors and the reserve capacity of the recipient, and avoid further technical issues.
