Maddrey's discriminant function (DF) is the traditional model for evaluating the severity and prognosis in alcoholic hepatitis and evaluates the efficacy of using alcoholic hepatitis steroid treatment. The Maddrey DF score is a predictive statistical model compares the subject's DF score with mortality prognosis within 30-day or 90-day scores.
These scores are used to evaluate the severity of the liver disease based on several lab values. The greater the score, the more severe the disease. Abstinence: Stopping further alcohol consumption is the number one factor for recovery in patients with alcoholic hepatitis. [16]
Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
Any value less than one is given a value of 1 (i.e. if bilirubin is 0.8 a value of 1.0 is used) to prevent subtraction from any of the three factors, since the natural logarithm of a positive number below 1 (greater than 0 and less than 1) yields a negative value. The etiology of liver disease was subsequently removed from the model because it ...
Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
They are most useful for cirrhosis and less useful for other stages of liver disease. [4] By 2008 it had been used in over 350,000 patients. [5] In 2006, the French National Authority for Health recommended the use of FibroTest as one of a number of first-line assessment tool for fibrosis with untreated chronic hepatitis C. [6]
A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, [1] arranged in a clockwise manner starting from the caudate lobe.
The extension to cases where there are more than two classes is relatively straightforward. [2] [6] [7] Let be the number of classes.Then multi-class KFD involves projecting the data into a ()-dimensional space using () discriminant functions
