Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
Jaundice01:25

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Area of Science:

  • Biomedical Engineering
  • Medical Diagnostics
  • Spectroscopy

Background:

  • Bilirubin monitoring is crucial for newborns due to jaundice risks.
  • Current methods (visual, transcutaneous bilirubinometry) have limitations in accuracy across skin tones and reliability.
  • A continuous monitoring device is under development to improve neonatal jaundice detection.

Purpose of the Study:

  • To develop a machine learning model for predicting the placement status of a continuous bilirubin monitoring device.
  • To establish a signal quality indication index for reliable bilirubin concentration estimates.
  • To validate the model's performance on adult skin spectra from different body areas.

Main Methods:

  • Utilized machine learning (ML), specifically Support Vector Machine (SVM) models.
  • Acquired skin spectra measurements from adult participants.
  • Trained and tested SVM models on spectral data from arm and forehead regions.

Main Results:

  • SVM models demonstrated high performance in predicting device placement status.
  • The developed method serves as an intermediate step for ensuring reliable bilirubin measurements.
  • Results indicate the potential for improving continuous monitoring device accuracy across diverse skin tones.

Conclusions:

  • Machine learning, particularly SVM, is effective for predicting optimal device placement for bilirubin monitoring.
  • This approach enhances signal quality assessment, crucial for accurate neonatal jaundice detection.
  • The findings support the development of more reliable, continuous, and non-invasive bilirubin monitoring systems.
