Liver assistive devices in acute liver failure: Current use and future directions
Bibliographic record
Abstract
Acute liver failure (ALF) is a rare syndrome where rapid deterioration of liver function occurs after an acute insult in a patient without prior chronic liver disease and leads to jaundice, hepatic encephalopathy (HE), and oftentimes multiorgan failure (MOF). At this time, the only definitive treatment for ALF is LT but some patients, particularly APAP-induced ALF patients, may have ongoing regenerative capacity of the liver and may not require LT with ongoing supportive management. As a result, extracorporeal liver support (ECLS) has been a topic of interest both as a bridge to LT and as a bridge to spontaneous recovery and aims to remove damaging toxins that further aggravate liver failure, stimulate regeneration of the liver, and improve pathophysiologic consequences of liver failure. There are currently two categories of ECLS (artificial and bioartificial). Artificial ECLS does not incorporate active hepatocytes and are based on the principles of filtration and adsorption and includes renal replacement therapy (RRT), plasma adsorption including plasma exchange and Prometheus (Fractionated Plasma Separation and Adsorption), and albumin dialysis including MARS (Molecular Adsorbent Recirculating System) and SPAD (Single Pass Albumin Dialysis). Bioartificial ECLS incorporates active hepatocytes (human or porcine in origin) to improve liver detoxification capacity and to support hepatic synthetic function and includes ELAD (Extracorporeal Liver Assist Device) and HepatAssist.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
