Holistic Patient Care in Primary Biliary Cholangitis: Managing Both the Disease and the Symptoms
Bibliographic record
Abstract
In the progressive, immune-mediated liver disease primary biliary cholangitis (PBC), the intrahepatic bile ducts are gradually destroyed over several years. The primary biochemical means to diagnose PBC, and assess progression and treatment response, is serum alkaline phosphatase (ALP). Further diagnostic criteria depend on antimitochondrial antibody (AMA) and specific antinuclear antibody status, and histological confirmation in some patients. First-line therapy for PBC is ursodeoxycholic acid (UDCA), which has been shown to improve biochemical indices of PBC and slow disease progression. However, major quality of life (QoL)-impacting symptoms of PBC, including pruritus and fatigue, are demonstrated to be independent of disease severity. There is evidence confirming that these symptoms negatively impact a number of aspects, including emotional status, ability to work, and social life, for some patients. In a symposium as part of the European Association for the Study of the Liver (EASL) International Liver Congress™ (ILC) 2022, Gideon Hirschfield, Toronto Centre for Liver Disease, University of Toronto, Ontario, Canada; Ana Lleo, Humanitas University and Humanitas Clinical and Research Centre, Milan, Italy; and David Jones, Newcastle University and Newcastle-upon-Tyne Hospitals NHS Foundation Trust, UK, discussed the holistic treatment of patients with PBC and whether goals of such should be more or equally dependent on biochemical status or impact on QoL. This discussion was expanded on in a session moderated by Jessica K. Dyson, Newcastle University and Newcastle-upon-Tyne Hospitals NHS Foundation Trust, UK.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
