Is There a Futility Discriminant Function Score for Alcoholic Hepatitis?

Hepatic artery duplex Doppler ultrasound in severe alcoholic hepatitis and correlation with Maddrey’s discriminant function

BACKGROUND Alcoholic hepatitis is associated with altered hepatic artery hemodynamics. Maddrey's discriminant function (MDF) can identify patients with poor prognosis (DF >32). We studied hepatic artery hemodynamic parameters of hepatic artery diameter (HAD), resistive index (RI) and pulsatility index (PI) in severe acute alcoholic hepatitis (SAAH) and for the presence of correlation of paramet...

Why Believe That There Is a God?

This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...

Vitamin D: Is There a New Era?

  Background: In recent decades, much interest has been focused on investigating new roles of vitamin D in human body beyond the mineral-ion homeostasis. Methods: By searching medical databases such as PubMed, over 16000 articles were found which have been published since 2000 on novel aspects of vitamin D in health and diseases. Results: Of great interest was the effects of vitamin D on ...

Is there a 'plenhaptic' function?

One approach to gauge the complexity of the computational problem underlying haptic perception is to determine the number of dimensions needed to describe it. In vision, the number of dimensions can be estimated to be seven. This observation raises the question of what is the number of dimensions needed to describe touch. Only with certain simplified representations of mechanical interactions c...
