Burnout Among Physicians of Specialties Dedicated to Liver Transplantation.

Burnout is increasingly relevant among healthcare professionals. The aim of this study is to describe the prevalence of burnout and other parameters of professional satisfaction among different specialists dedicated to Liver Transplantation (LT) in transplant teams. A working group from the Spanish Society of LT designed a survey with 39 questions evaluating the prevalence of parameters related to professional satisfaction, including burnout.

Hepatocellular carcinoma risk-stratification based on ASGR1 in circulating epithelial cells for cancer interception.

Lack of diagnostic and prognostic biomarkers in hepatocellular carcinoma impedes stratifying patients based on their risk of developing cancer. The aim of this study was to evaluate phenotypic and genetic heterogeneity of circulating epithelial cells (CECs) based on asialoglycoprotein receptor 1 (ASGR1) and miR-122-5p expression as potential diagnostic and prognostic tools in patients with hepatocellular carcinoma (HCC) and liver cirrhosis (LC). Peripheral blood samples were extracted from LC and HCC patients at different disease stages.

Circulating Tumor Cells Enumeration from the Portal Vein for Risk Stratification in Early Pancreatic Cancer Patients.

Background: Effective biomarkers are needed to enable personalized medicine for pancreatic cancer patients. This study analyzes the prognostic value, in early pancreatic cancer, of single circulating tumor cell (CTC) and CTC clusters from the central venous catheter (CVC) and portal blood (PV).

Methods: In total, 7 mL of PV and CVC blood from 35 patients with early pancreatic cancer were analyzed.

Harmonized D-dimer levels upon admission for prognosis of COVID-19 severity: Results from a Spanish multicenter registry (BIOCOVID-Spain study).

Coagulopathy is a key feature of COVID-19 and D-dimer has been reported as a predictor of severity. However, because D-dimer test results vary considerably among assays, resolving harmonization issues is fundamental to translate findings into clinical practice. In this retrospective multicenter study (BIOCOVID study), we aimed to analyze the value of harmonized D-dimer levels upon admission for the prediction of in-hospital mortality in COVID-19 patients.

Characteristics and laboratory findings on admission to the emergency department among 2873 hospitalized patients with COVID-19: the impact of adjusted laboratory tests in multicenter studies. A multicenter study in Spain (BIOCOVID-Spain study).

Identification of predictors for severe disease progression is key for risk stratification in COVID-19 patients. We aimed to describe the main characteristics and identify the early predictors for severe outcomes among hospitalized patients with COVID-19 in Spain. This was an observational, retrospective cohort study (BIOCOVID-Spain study) including COVID-19 patients admitted to 32 Spanish hospitals.

Epidemiological pattern, incidence, and outcomes of COVID-19 in liver transplant patients.

Background & Aims: The incidence and outcomes of coronavirus disease 2019 (COVID-19) in immunocompromised patients are a matter of debate.

Methods: We performed a prospective nationwide study including a consecutive cohort of liver transplant patients with COVID-19 recruited during the Spanish outbreak from 28 February to 7 April, 2020. The primary outcome was severe COVID-19, defined as the need for mechanical ventilation, intensive care, and/or death.

Impact of Early Initiated Everolimus on the Recurrence of Hepatocellular Carcinoma After Liver Transplantation.

Background: Many centers implement everolimus-based immunosuppression in liver transplant patients with hepatocellular carcinoma. We aimed to explore the potential impact of early initiated everolimus on tumor recurrence after liver transplantation.

Methods: This study included 192 patients with hepatocellular carcinoma undergoing liver transplantation among who 64 individuals were prospectively enrolled (2012-2015) and received early initiated everolimus (ie, started between postoperative day 15 to 21), whereas the remaining 128 patients acted as historical controls without everolimus.

Influence of donor liver CYP3A4*20 loss-of-function genotype on tacrolimus pharmacokinetics in transplanted patients.

Objective: Cytochrome P450 3A4 (CYP3A4) metabolizes about half of all drugs on the market; however, the impact of CYP3A4 loss-of-function variants on drug exposures remains poorly characterized. Here, we report the effect of the CYP3A4*20 frameshift allele in two Spanish liver transplant patients treated with tacrolimus.

Patients And Methods: A series of 90 transplanted patients (with DNA available for 89 of the recipients and 76 of the liver donors) treated with tacrolimus were included in the study.

Minimally invasive distal pancreatectomy A retrospective review of 30 cases.

Objectives: Pancreatic surgery has been greatly influenced by the advent of laparoscopic surgery and increasing experience in its performance and by advances in techniques and surgical devices. This study aimed to represent two centers' initial experiences in laparoscopic distal pancreatic surgery.

Methods: This study was a bi-centric study including 30 patients undergoing distal pancreatectomy for pancreatic disorders.

Nitric Oxide Synthase Type III Overexpression By Gene Therapy Exerts Antitumoral Activity In Mouse Hepatocellular Carcinoma.

Hepatocellular carcinoma develops in cirrhotic liver. The nitric oxide (NO) synthase type III (NOS-3) overexpression induces cell death in hepatoma cells. The study developed gene therapy designed to specifically overexpress NOS-3 in cultured hepatoma cells, and in tumors derived from orthotopically implanted tumor cells in fibrotic livers.

Implication of the presence of a variant hepatic artery during the Whipple procedure.

Introduction: The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD) in patients with or without a variant hepatic artery arising from superior mesenteric artery.

Material And Methods: We reviewed 151 patients with periampullary tumoral pathology.

Point-of-care haemostasis monitoring during liver transplantation reduces transfusion requirements and improves patient outcome.

Background: Optimal haemostasis management can improve patient outcomes and reduce blood loss and transfusion volume in orthotopic-liver-transplant (OLT).

Methods: We performed a prospective study including 200 consecutive OLTs. The first 100 patients were treated according to the clinic's standards and the next 100 patients were treated using the new point-of-care (POC)-based haemostasis management strategy.

Conversion from calcineurin inhibitors to mTOR inhibitors stabilizes diabetic and hypertensive nephropathy after liver transplant.

Aim: To investigate if conversion to the mammalian target of rapamycin inhibitors (mTORi) improves renal function in diabetic and/or hypertensive liver transplant patients immunosuppressed with tacrolimus or cyclosporine.

Methods: The study included 86 liver graft recipients immunosuppressed with mTORi treatment after orthotopic liver transplantation (OLT), including all liver recipients with worsening renal function before conversion to mTORi (n = 55 patients) and recipients with normal renal function who converted to mTORi for other reasons (n = 31 patients). We identified patients with diabetes mellitus (n = 28), arterial hypertension (n = 27), proteinuria (n = 27) and all three factors (n = 8) (some patients have hypertension and diabetes and no proteinuria).

Improving outcomes in pancreatic cancer: key points in perioperative management.

This review focused in the perioperative management of patients with pancreatic cancer in order to improve the outcome of the disease. We consider that the most controversial points in pancreatic cancer management are jaundice management, vascular resection and neo-adjuvant therapy. Preoperative biliary drainage is recommended only in patients with severe jaundice, as it can lead to infectious cholangitis, pancreatitis and delay in resection, which can lead to tumor progression.

Impact of donor and recipient CYP3A5 and ABCB1 genetic polymorphisms on tacrolimus dosage requirements and rejection in Caucasian Spanish liver transplant patients.

Studies of liver transplant (LT) patients, mainly in Asians, have evaluated the influence of the CYP3A5*1 allele and P-glycoprotein gene ABCB1 on tacrolimus pharmacokinetics or biopsy-proven acute rejection (BPAR) incidence, with no conclusive results. To investigate these issues, 98 Caucasian Spanish LT patients with tacrolimus, mycophenolate mofetil and steroids and 88 cadaveric donors were genotyped for the SNPs CYP3A5 6986G>A, ABCB1 1236C>T, ABCB1 2677G>A/T and ABCB1 3435C>T;. On day 7 post-LT, patients with a native CYP3A5*1 allele had significantly lower tacrolimus trough concentrations C0 (P = .

Targeting hepatoma using nitric oxide donor strategies.

Aims: The study evaluated the role of increased intracellular nitric oxide (NO) concentration using NO donors or stably NO synthase-3 (NOS-3) overexpression during CD95-dependent cell death in hepatoma cells. The expression of cell death receptors and caspase activation, RhoA kinase activity, NOS-3 expression/activity, oxidative/nitrosative stress, and p53 expression were analyzed. The antitumoral activity of NO was also evaluated in the subcutaneous implantation of NOS-3-overexpressing hepatoma cells, as well NO donor injection into wild-type hepatoma-derived tumors implanted in xenograft mouse models.

[Descriptive study of infectious complications in 109 consecutive liver transplant recipients].

Introduction: Infectious disease is a common, serious complication in liver transplant recipients. The etiology of these infections undergoes changes related with technical advances, prophylaxis, and local epidemiology.

Methods: Prospective study in patients who underwent liver transplantation from July 2003 to December 2005 at the Hospital Universitario Virgen del Rocío.

[Etiology and diagnosis of severe retroperitoneal hematoma: therapeutic options and surgical indication].

Retroperitoneal hematoma is a rare entity with clinical consequences that vary according to the speed and amount of bleeding. Thus, it may be asymptomatic, in which case it is usually diagnosed incidentally through imaging tests, or severe, in which case the most common symptoms are pain and hypovolemic shock. We report three cases of severe retroperitoneal hematoma.
