We report a repositioning maneuver of a dislocated Avalon Elite dual lumen catheter during ongoing veno-venous ECMO support. The inferior tip of the catheter dislocated into a liver vein, which was accompanied by a dramatic decrease in pump flow. After standard repositioning maneuvers under transthoracic echocardiographic guidance had failed, a special guiding sheath was inserted into the main lumen through a Y-connector with a valve. Over this valve, a stiff wire could be placed into the inferior vena cava to help guiding the catheter back into the correct position...

Metabolic syndrome, an etiological factor in non-alcoholic fatty liver disease (NAFLD), is often present in hemodialysis patients. Little is known about the prevalence of, and factors associated with, liver fibrosis in hemodialysis populations. We used transient elastography (TE) to investigate these phenomena. 659 patients treated with chronic hemodialysis were enrolled. We excluded those with excess alcohol intake, liver stiffness measurement (LSM) failure, or unreliable LSM values. LSM ≥8.0 kPa was used as a cutoff suggesting clinically relevant fibrosis...

BACKGROUND: Controlled attenuation parameter (CAP) and liver stiffness (LS) measured by transient elastography (TE, Fibroscan®) have been used for steatosis and fibrosis assessment. We evaluated the effect of meal intake on CAP and LS values. METHODS: Forty patients who had had a liver biopsy within the previous month were recruited. The biopsy was graded for fibrosis (F) and steatosis (S) stagings. TE was performed after overnight fasting (baseline values) and 15, 30, 45, 60, 90, and 120 min following the intake of a standard commercial formula meal, and every 30 min until LS and CAP values returned to baseline...

Liver cirrhosis is one of the main causes of death and disability-adjusted life-years worldwide. Generally, cirrhosis develops after a long period of liver-cell injury that leads to the deposition of collagen, leading to progressive fibrosis and nodule formation in the liver tissue. Most patients are diagnosed in late stages when liver decompensation or liver cancer develops. The diagnosis is rarely made in early stages-when liver fibrosis is mild to moderate but cirrhosis is not yet established-because the disease is asymptomatic...

Salinomycin has recently been identified as an antitumour drug for several types of cancer stem cell (CSC) treatments. However, the effects of salinomycin on the migratory and invasive properties of liver cancer stem cells (LCSCs) are unclear. In present study, we investigated the effect of salinomycin on the migration and invasion of LCSCs, and examined the molecular mechanisms underlying the anticancer effects of salinomycin. Here we showed that the migration and invasion of LCSCs were significantly suppressed in a salinomycin dose-dependent manner...

OBJECTIVES: Although right ventricular failure (RVF) is a major concern after left ventricular assist device (LVAD) implantation, methodologies to evaluate RV function remain limited. Liver stiffness (LS), which is closely related to right-sided filling pressure and may indicate RVF severity, could be non-invasively and repeatedly assessed using transient elastography. Here we investigated the suitability of LS as a parameter of RV function in pre- and post-LVAD periods. METHODS: The study included 55 patients with LVAD implantation as a bridge to transplantation between 2011 and 2015 whose LS was assessed using transient elastography...
