ANION GAP ACIDOSIS: GOLD-MARK makes a MARK:

GOLDMARK  is the new MUD PILES
A new mnemonic has been created in the last few years for anion gap acidosis. 


Glycols( ethylene glycol, propylene glycol)
Oxoproline
L- lactate
D-lactate
Methanol
Aspirin
Renal failure
Ketoacidosis

Two popular mnemonics were often used to remember the major causes of the high-gap metabolic acidoses. The first is KUSMALE which represents Ketoacidosis, Uremia, Salicylate poisoning, Methanol, Aldehyde (paraldehyde), Lactate, and Ethylene glycol. 
The second is MUD PILES( most popular), spells out Methanol, Uremia, Diabetic ketoacidosis, Paraldehyde, Iron (and Isoniazid), Lactate, Ethylene glycol, and Salicylate.

Why GOLDMARK then? The causes have changed in the 21st century. We barely see any more paraldehyde any more, neither we see that much Iron and INH related causes.
Newer causes: D-lactate: seen with short gut syndrome( especially after sugary drinks), diabetes can lead to d-lactate as well. Other new causes is pyroglutamic acid ( oxoproline) seen with chronic Tylenol use. Finally, propylene glycol infusion that is usually found in lorazepam, phenobarb and banana bags.
