Association between artificial nutrition in brain dead donors and early allograft function in liver transplant recipients: an observational study.

Background: The role of nutrition in donor after brain deaths (DBDs) has yet to be adequately discussed. The primary aim of this study was to investigate whether the nutritional intake in the 48 h before organ retrieval may play a role on the graft functional recovery assessed with Model for Early Allograft Function (MEAF) Score.

Methods: Single-center retrospective study evaluating all liver transplants performed at the University Hospital of Udine from January 2010 to August 2020.

Current practice with grafts with multiple renal arteries in kidney transplantation: role of the methylene blue in the lower pole.

Kidneys with multiple renal arteries (MRAs) from different patches, may provide to the surgeon additional technical difficulties that make kidney transplants very challenging. MRAs have been largely debated over the years whether to be anastomosed or not due to the disappointing outcomes when it comes to inappropriate ligation or anastomosis.  Some authors empirically reassure that smaller branches can be safely ligated and dissected without intraoperative and postoperative complications or compromising the functional recovery of the graft.

Incidence and Risk Factors for Venous Thromboembolism in Female Patients Undergoing Breast Surgery.

Albeit it does not have the highest venous thromboembolism (VTE) incidence compared to other neoplasms, breast cancer contributes to many VTE events because it is the most diagnosed tumor in women. We aim to analyze the occurrence and timing of VTE during the follow-up of patients who underwent breast surgery, the possible correlated factors, and the overall survival. This retrospective study included all female patients diagnosed with mammary pathology and surgically treated in our clinic between January 2002 and January 2012.

Assessment of hepatic steatosis based on needle biopsy images from deceased donor livers.

Background: Assessment of hepatic steatosis (HS) before transplantation requires the pathologist to read a graft biopsy. A simple method based on the evaluation of images from tissue samples with a smartphone could expedite and facilitate the liver selection. This study aims to assess the degree of HS by analysing photographic images from liver needle biopsy samples.

The Challenging Management of an Intracardiac Thrombus in a Liver Transplant Patient at the Reperfusion Phase: A Case Report and Brief Literature Review.

The exact origin of intracardiac thrombi formation during orthotopic liver transplant remains unknown. The altered balance between hypercoagulability, hypocoagulation, and endothelial dysfunction associated with end-stage liver disease is thought to play a pivotal role. Venous stasis, vascular clamping, and reperfusion could also contribute to clot formation.

Association between the donor to recipient ICG-PDR variation rate and the functional recovery of the graft after orthotopic liver transplantation: A case series.

Background: Despite current advances in liver transplant surgery, post-operative early allograft dysfunction still complicates the patient prognosis and graft survival. The transition from the donor has not been yet fully understood, and no study quantifies if and how the liver function changes through its transfer to the recipient. The indocyanine green dye plasma disappearance rate (ICG-PDR) is a simple validated tool of liver function assessment.

Association between indocyanine green clearance test and ischemic type biliary lesions within one year after orthotopic liver transplantation.

Background: Ischemic type biliary lesions (ITBLs), a particular subset of non-anastomotic biliary strictures (NAS), are characterized by intra and extrahepatic strictures that occur in the absence of either hepatic artery thrombosis or stenosis. When they occur within the first year after liver transplantation their development is mostly related to ischemia-reperfusion injury (IRI). The indocyanine green plasma disappearance rate (ICG-PDR) might be able to predict the probability of IRI-induced graft damage after liver transplantation.

Postoperative Trends and Prognostic Values of Inflammatory and Nutritional Biomarkers after Liver Transplantation for Hepatocellular Carcinoma.

Preoperative inflammatory biomarkers such as the Platelet-to-Lymphocyte Ratio (PLR) and the Neutrophil-to-Lymphocyte Ratio (NLR) strongly predict the outcome in surgically treated patients with hepatocellular carcinoma (HCC), while nutritional biomarkers such as the Controlling Nutritional Status (CONUT) and the Prognostic Nutritional Index (PNI) show an analogue prognostic value in hepatic resection (HR) but not in liver transplant (LT) cases. Data on the impact of LT on the inflammatory and nutritional/metabolic function are heterogeneous. Therefore, we investigated the post-LT trend of these biomarkers up to postoperative month (POM) 12 in 324 HCC patients treated with LT.

Hepatocellular carcinoma and the risk of de novo malignancies after liver transplantation - a multicenter cohort study.

Patients with hepatocellular carcinoma (HCC) are at high risk of second primary malignancies. As HCC has become the leading indication of liver transplant (LT), the aim of this study was to investigate whether the presence of HCC before LT could influence the onset of de novo malignancies (DNM). A cohort study was conducted on 2653 LT recipients.

Can Preoperative Multidetector Computed Tomography Identify Predictive Features of Difficult Native Hepatectomy at Liver Transplantation?

Background: Native hepatectomy represents the most demanding surgical step during orthotopic whole liver transplantation (LT). The surgical risk assessment of LT candidates is currently mainly based on clinical and laboratory data, but even preoperative imaging data may be predictive of a complex native hepatectomy.

Methods: A retrospective study on a cohort of 110 LT recipients was conducted.

Is there any correlation between liver graft regeneration and recipient's pretransplant skeletal muscle mass?-a study in extended left lobe graft living-donor liver transplantation.

Background: The end-stage liver disease causes a metabolic dysfunction whose most prominent clinical feature is the loss of skeletal muscle mass (SMM). In living-donor liver transplantation (LDLT), liver graft regeneration (GR) represents a crucial process to normalize the portal hypertension and to meet the metabolic demand of the recipient. Limited data are available on the correlation between pre-LDLT low SMM and GR.

Impact of kidney transplant morbidity on elderly recipients' outcomes.

Background And Aims: Nowadays, advanced age does not represent an absolute contraindication to kidney transplantation (KT). However, aging is frequently associated with multiple comorbidities and lower performance status, making KT candidates less surgically fit. Limited data are available on the impact of KT morbidity on elderly recipients' outcomes.

Indocyanine green dye clearance test: early graft (dys)-function and long-term mortality after liver transplant. Should we continue to use it? An observational study.

Early allograft dysfunction (EAD) can be a serious complication in the immediate postoperative period following liver transplantation. Our aim was to study the prognostic role of the indocyanine green plasma disappearance rate (ICG-PDR) in predicting early and late EAD and mortality at 3 and 12 months and 5 years after liver transplantation. ICG-PDR values were also assessed for association with the Donor Risk Index (DRI).

Effects of Delayed Hypothermic Machine Perfusion on Kidney Grafts with a Preliminary Period of Static Cold Storage and a Total Cold Ischemia Time of Over 24 Hours.

BACKGROUND Hypothermic machine perfusion (HMP) appears to exert a reconditioning effect on the ischemic damage of kidney grafts. However, some concerns still remain about its real effectiveness when it is delayed after a preliminary period of static cold storage (SCS) or with prolonged overall cold ischemia time (CIT). MATERIAL AND METHODS The effect of HMP on hemodynamic, metabolic, histological and ultrastructural features of grafts was investigated in 21 single-kidney grafts treated with a delayed HMP after SCS and with a total CIT of over 24 h.

Controlling Nutritional Status score does not predict patients' overall survival or hepatocellular carcinoma recurrence after deceased donor liver transplantation.

Background: The Controlling Nutritional Status (CONUT) score is a newly developed laboratory-derived immunonutritional score which has been validated as prognostic marker for survival and tumor recurrence in surgically treated patients with various tumor types, including hepatocellular carcinoma (HCC). The aim of the present study was to test the CONUT score performance in HCC patients treated with liver transplantation (LT).

Methods: A retrospective study on a bi-centers cohort of 280 HCC patients submitted to LT between 2006 and 2017 was performed.

Surgical Complications Requiring an Early Relaparotomy in HIV-Infected Liver Transplant Recipients: Risk Factors and Impact on Survival.

Aim: We aimed to analyze the risk factors for early surgical complications requiring relaparotomy and the related impact on overall survival (OS) in HIV-infected patients submitted to liver transplantation.

Methods: We performed a retrospective study on a nationwide multicenter cohort of 157 HIV-infected patients submitted to liver transplantation in 6 Italian transplant units between 2004 to 2014.

Results: The median preoperative model for end-stage liver disease score was 18 (interquartile range 12-26.

Risk Factors for Graft Loss Due to Acute Vascular Complications in Adult Renal Transplantation Using Grafts Without Vascular Anomalies.

Background: Vascular complications are the main cause of early graft loss in renal transplant (RT). A graft with multiple vessels represents the most validated risk factor. The aim of the present study was to identify potential predictive factors for acute vascular complications causing graft loss when graft vascular anomalies are excluded.

Gastrointestinal Perforations in Adult Whole-Liver Transplant Patients: Clinical, Radiologic, and Histopathologic Analysis.

Background: Gastrointestinal perforation (GIP) is a rare complication after adult liver transplant (LT) associated with high morbidity and mortality. Limited data are available about clinical risk factors and underlying pathogenic mechanisms.

Methods: The retrospective study included all GIP cases from a consecutive cohort of 361 LT recipients during the period 2005-2017.

MeltDose Technology vs Once-Daily Prolonged Release Tacrolimus in De Novo Liver Transplant Recipients.

Background: An extended-release formulation of tacrolimus designed for once-daily administration (LCP-TAC) is a new prolonged-release tacrolimus (TAC-PR) formulation using a drug delivery technology designed to enhance the bioavailability of drugs compared with TAC-PR. The aim of this study was to retrospectively compare de novo administration of LCP-TAC and TAC-PR for therapeutic trough levels and daily dosage during the first 30 days after first liver transplant (LT).

Methods: A total of 35 patients submitted to first LT between 2016 and 2018 were retrospectively enrolled: 16 received LCP-TAC, while 19 received TAC-PR as de novo immunosuppression.

Improved Survival in Liver Transplant Patients Receiving Prolonged-release Tacrolimus-based Immunosuppression in the European Liver Transplant Registry (ELTR): An Extension Study.

Background: We compared, through the European Liver Transplant Registry, long-term liver transplantation outcomes with prolonged-release tacrolimus (PR-T) versus immediate-release tacrolimus (IR-T)-based immunosuppression. This retrospective analysis comprises up to 8-year data collected between 2008 and 2016, in an extension of our previously published study.

Methods: Patients with <1 month follow-up were excluded; patients were propensity score matched for baseline characteristics.

Early post-liver transplant surgical morbidity in HIV-infected recipients: risk factor for overall survival? A nationwide retrospective study.

The aim of the study was to analyse the risk factors for early surgical complications requiring relaparotomy and the related impact on overall survival (OS) in HIV-infected patients submitted to liver transplantation. Thus a retrospective investigation was conducted on a nationwide multicentre cohort of 157 HIV patients submitted to liver transplantation in six Italian Transplant Units between 2004 and 2014. An early relaparotomy was performed in 24.

Chronological changes in skeletal muscle mass following living-donor liver transplantation: An analysis of the predictive factors for long-term post-transplant low muscularity.

Aim: Sarcopenia is associated with high morbidity and mortality before and after liver transplantation (LT). The aim of the study was to evaluate the chronological changes in skeletal muscle mass (SMM) at different time points post-LT and to identify the risk factors for long-term low SMM.

Methods: The skeletal muscle index at L3 level (L3-SMI) was used for muscle mass measurement, and the recommended cutoff values of the Japanese Society of Hepatology guidelines were used as criteria for defining low muscularity.
