Background & Aims: The impact of gender and donor/recipient gender mismatch on LT outcomes is controversial. The aim of this study was to compare outcomes of LT in Europe, using the ELTR database, between male and female recipients, including donor/recipient gender mismatch. Methods: Recipient, donor and transplant characteristics were compared between male and female patients. Patient survival was compared between groups, and the impact of donor/recipient gender matching as well as donor and recipient anthropometric characteristics were evaluated as potential risk factors for post-LT death/graft loss. Results: A total of 46,334 LT patients were evaluated (70.5% men and 29.5% women). Ten-year survival rate was significantly higher in female than in male recipients (66% vs 59%, P < .

Background and Aims: Acute kidney injury (AKI) commonly occurs in patients with decompensated cirrhosis. Urinary neutrophil gelatinaseassociated lipocalin (uNGAL) could help discriminate between different etiologies of AKI. The aim of this study was to investigate the use of uNGAL in (1) the differential diagnosis of AKI, (2) predicting the response to terlipressin and albumin in patients with hepatorenal syndrome-AKI (HRS-AKI), and (3) predicting in-hospital mortality in patients with AKI.Approach and Results: One hundred sixty-two consecutive patients with cirrhosis and AKI were included from 2015 to 2020 and followed until transplant, death, or 90 days. Standard urinary markers and uNGAL were measured. Data on treatment, type, and resolution of AKI were collected. Thirty-five patients (21.6%) had prerenal AKI, 64 (39.5%) HRS-AKI, 27 (16.7%) acute tubular necrosis-AKI (ATN-AKI), and 36 (22.2%) a mixed form of AKI. Mean values of uNGAL were significantly higher in ATN-AKI than in other types of AKI (1162 ng/ml [95% CI 423-2105 ng/ml] vs. 109 ng/ml [95% CI 52-192 ng/ ml]; p < 0.001). uNGAL showed a high discrimination ability in predicting ATN-AKI (area under the receiver operating characteristic curve, 0.854; 95% CI 0.767-0.941; p < 0.001). The best-performing threshold was found to be 220 ng/ml (sensitivity, 89%; specificity, 78%). The same threshold was independently associated with a higher risk of nonresponse (adjusted OR [aOR],
