What is the probability of being too old for salvage transplantation after hepatocellular carcinoma resection?

BackgroundThe strategy of salvage transplantation for patients with hepatocellular carcinoma is based on the premise that tumour recurrence will be still transplantable at the time of recurrence. However, patients can not only present non-transplantable recurrence but can also be over the age limit accepted for transplantation.AimsTo measure the risk of being too old for salvage transplantation of patients resected for hepatocellular carcinoma within Milan criteria.MethodsA Markov simulation model was developed on the basis of published literature.ResultsThe risk of being too old for salvage transplantation depends on the time-span between age at hepatic resection and age limit, and the expected median waiting-time. Patients resected at an age 2 or 3 years below the age limit carry a risk of being too old that overcomes the probability of receiving transplantation. Salvage strategy can cause harm that depends on the tumour characteristics and degree of portal hypertension, becoming maximal for patients with multiple tumours, clinical signs of portal hypertension and increased bilirubin levels.ConclusionsThe best strategy to adopt should be balanced between the risk of being too old and the expected transplant benefit, but salvage strategy could be pursued if it did not turn into significant harm in comparison to primary transplantation.

Management of fluid balance in continuous renal replacement therapy: technical evaluation in the pediatric setting

Fluid overload control and fluid balance management represent very important factors in critically ill children requiring renal replacement therapy. A relatively high fluid volume administration in children and neonates is often necessary to deliver adequate amounts of blood derivatives, vasopressors, antibiotics, and parenteral nutrition. Fluid balance errors during pediatric continuous renal replacement therapy (CRRT) might significantly impact therapy delivery and have been described as potentially lethal. The aim of this study was to evaluate the accuracy of delivered vs. prescribed net ultrafiltration (UF) during CRRT applied to 2 neonates and 2 small children, either as dialytic treatment alone or during extracorporeal membrane oxygenation (ECMO). In accordance with an Acute Dialysis Quality Initiative workgroup statement, net UF was defined as the "overall amount of fluid extracted from the patient in a given time". Mean prescribed net UF was 18.5 ml/h (SD=6.7) during neonatal treatments and 70.3 ml/h (SD=22.5) during CRRT in small children. Daily net UF ranged from 200 mL to about 600 mL in the 2 neonates and from 1,200 to 1800 mL in the 2 children. The percentage error of delivered net UF ranged from -1.6% to 5.8% of the prescribed level. The mean error of the ECMO/CRRT patients was 3.024 ml/h vs. 0.45 m/h for the CRRT patients (p<0.001). The same difference was not evident when the 2 neonates were compared with the 2 small children (without considering the presence of ECMO). CRRT and net UF delivery appeared to be accurate, safe, and effective in this small cohort of high-risk pediatric patients.
