rognostic model derived using machine learning methodology performed better than the NSQIP EP in predicting 30-day UD among low risk patients undergoing HP surgery. Early allograft dysfunction (EAD) is associated with decreased graft and patient survival rates. This study aimed to identify the severity of EAD and develop a predictive model for EAD after donation after circulatory death (DCD) liver transplantation (LT). Furthermore, the influence of operative time on EAD incidence was also evaluated. In this retrospective, multicentre cohort study, nomograms were established based on a single-centre training cohort (n=321) and validated in a 3-center validation cohort (n=501). The incidence rate of EAD was 46.4% (149/321) in the training cohort and 40.5% (203/501) in the validation cohort. Of the 149 EAD patients in the training cohort, 77 patients with either elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) were classified as having EAD type A, and the rest of the EAD patients were classified as having EAD type B. Recipients with EAD type B had lower graft and patient survival rates than recipients with EAD type A (P=0.043 and 0.044, respectively). We further developed a nomogram to predict EAD (graft weight, cold ischemia time, donor age, model for end-stage liver disease (MELD) score) and another nomogram to predict EAD type B (graft weight, cold ischemia time, MELD score). The nomograms for the prediction of EAD and EAD type B had good discrimination [concordance index (C-index) =0.712 (0.666-0.758), 0.707 (0.641-0.773)] and calibration [Hosmer-Lemeshow (HL) P=0.384, P=0.425] in the validation cohort. An increased operative time (>6 h) was associated with increased EAD and EAD type B incidence in the high-risk group (P=0.005, P=0.020, respectively). EAD type B was associated with decreased graft and patient survival rates. The novel nomograms effectively predicted the incidence of EAD and EAD type B in DCD LT patients. EAD type B was associated with decreased graft and patient survival rates. The novel nomograms effectively predicted the incidence of EAD and EAD type B in DCD LT patients. The role of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in comparison to portal vein embolization (PVE) is debated. The aim of this study was to compare successful resection rates (RR) with upfront ALPPS PVE with rescue ALPPS on demand and to compare the hypertrophy of the liver between ALPPS and PVE plus subsequent rescue ALPPS. A retrospective analysis of all patients treated with PVE for colorectal liver metastasis (CRLM) or ALPPS (any diagnosis, rescue ALPPS included) at five Scandinavian university hospitals during the years 2013-2016 was conducted. A Chi-square test and a Mann-Whitney U test were used to assess the difference between the groups. A successful RR was defined as liver resection without a 90-day mortality. A total of 189 patients were included. Successful RR was in 84.5% of the patients with ALPPS upfront and in 73.3% of the patients with PVE and rescue ALPPS on demand (P=0.080). The hypertrophy of the future liver remnants (FLRs) with ALPPS upfront was 71% (48-97%) compared to 96% (82-113%) after PVE and rescue ALPPS (P=0.010). Upfront ALPPS offers a somewhat higher successful RR than PVE with rescue ALPPS on demand. The sequential combination of PVE and ALPPS leads to a higher overall degree of hypertrophy than upfront ALPPS. Upfront ALPPS offers a somewhat higher successful RR than PVE with rescue ALPPS on demand. The sequential combination of PVE and ALPPS leads to a higher overall degree of hypertrophy than upfront ALPPS.Dogs provide a physiological paradox In domestic dogs, small breeds live longer lives than large breed dogs. Comparatively, a wild canid can be a similar size than many large breed dogs and outlive their domestic cousin. We have
