Ghinolfi, Dondossola, and colleagues from Italy in this issue describe a significant step in utilization of organs that are currently not transplanted. The particular constraints that apply to DCD organ donation in Italy (the requirement for 20 minutes of asystole on ECG) provide the incentive to innovate: this length of warm ischemia effectively precludes conventional organ retrieval. However, the approach described is not only important in Italy but also relevant anywhere DCD liver transplantation (LT) is undertaken ...

Interleukin-33 (IL-33), an alarmin released during tissue injury, facilitates the development of cholangiocarcinoma (CCA) in a murine model. However, it is unclear whether IL-33 is associated with human CCA. The aim of this study was to support the following hypothesis: IL-33 is released during hepatectomy for CCA, subsequently facilitating the development of subclinical CCA and eventually leading to recurrent disease. IL-33 expression was assessed in various samples from both humans and mice including resected liver and paired plasma samples collected at hepatectomy and after surgery, and its influences on recurrent disease and patient prognosis were determined...

BACKGROUND AND AIMS: Liver X receptors (LXRs) exert anti-inflammatory effects even though their hepatic activation is associated with hypertriglyceridemia and hepatic steatosis. Selective induction of LXRs in the gut might provide protective signal(s) in the aberrant wound healing response that induces fibrosis during chronic liver injury, without hypertriglyceridemic and steatogenic effects. METHODS: Mice with intestinal constitutive LXRα activation (iVP16-LXRα) were exposed to intraperitoneal injection of carbon tetrachloride (CCl4 ) for 8 weeks, and in vitro cell models were used to evaluate the beneficial effect of high-density lipoproteins (HDL)...

Liver transplantation (LT) for alcohol-associated liver disease (ALD) has now become the most common indication for LT.(1). Patients with alcohol use disorder (AUD) have excellent outcomes after LT with most recipients remaining abstinent or drinking in a moderate fashion(2). The "6-month" rule, which imposed a fixed interval of sobriety prior to LT consideration, has increasingly been abandoned as scientific evidence demonstrates such intervals to be, at best, a weak predictor of future harmful alcohol relapse and arbitrarily excluding many patients who would do well with LT and who will almost certainly die otherwise(3)...

Liver transplantation (LT) using allografts from hepatitis C virus (HCV)-viremic/nucleic acid testing-positive donors' (DNAT+) organs into HCV-aviremic recipients (rHCV-) has been limited due to nearly universal HCV transmission and concerns regarding availability, safety, and efficacy post-LT with direct-acting antiviral (DAAs) therapy. We report our experience of LT using DNAT+ organs into rHCV- as a routine standard of care. Following verification of DAAs access, absence of critical drug-drug interactions (DDIs) with DAAs, and informed consent, allocated DNAT+ organs were offered to patients on the waiting list for LT irrespective of recipient HCV status...

BACKGROUND: Assessment of bone density is an important part of liver transplant (LT) evaluation for early identification and treatment of osteoporosis (OP). Dual-energy X-ray absorptiometry (DXA) is currently the standard clinical test for osteoporosis; however, it may contribute to the appointment burden on LT candidates during the cumbersome evaluation process and there are limitations affecting its accuracy. In this study, we evaluate the utility of biomechanical analysis of vertebral images obtained during triple phase dual-energy abdominal CT (TPCT) in diagnosing osteoporosis among LT candidates...

Besides insulin-mediated transport of glucose into the cells, an important role is also played by the non-insulin-mediated transport. This latter process is called glucose effectiveness (acronym SG ), which is estimated by modeling of glucose and insulin data after an intravenous glucose administration and accounts for ≈70% of glucose disposal. This review summarizes studies on SG , mainly in humans and rodents with focus on results achieved in model experiments in mice. In humans, SG is reduced in type 2 diabetes, in obesity, in liver cirrhosis and in some elderly populations...

Growth differentiation factor 15 (GDF15), a member of the TGF-β superfamily, is a prognostic biomarker of cervical cancer. In addition, GDF15 has been reported to enhance the migration of colorectal cancer cells and liver cancer stem-like cells. However, the mechanism by which GDF15 promotes cervical cancer cell migration is not completely understood. Here, we report that GDF15 expression is enhanced in cervical cancer tissues as well as in cultured cervical cancer cells. ShGDF15 transfection markedly inhibited expression of Vimentin, N-cadherin, and Snail1, and resulted in upregulation of E-cadherin expression in HT-3 and HeLa cells...

Oral Direct-acting antivirals (DAAs) are safe, highly effective altering disease burden and prognosis in hepatitis C patients. Sustained virologic response (SVR) is achieved nowadays in more than 90 percent of the treated patients and related to the improvements in functions of the liver, fibrosis plus survival. Furthermore, portal hypertension is thought to be improved with achievement of virological response, parallel to the improvements in hepatic inflammation and fibrosis.We aimed assess the recurrence rate of esophageal varices by long term follow up in patients treated with different DAAs regimens who had achieved SVR...

Modern medical care produces large volumes of multi-modal patient data, which many clinicians struggle to process and synthesize into actionable knowledge. In recent years, artificial intelligence (AI) has emerged as an effective tool in this regard. The field of hepatology is no exception, with a growing number of studies published that apply artificial intelligence techniques to the diagnosis and treatment of liver diseases. These have included Machine Learning algorithms (such as regression models, Bayesian networks, and support vector machines) to predict disease progression, the presence of complications, and mortality; Deep Learning algorithms to enable rapid, automated interpretation of radiologic and pathologic images; and Natural Language Processing to extract clinically meaningful concepts from vast quantities of unstructured data in Electronic Health Records...
