.transplantation

.supplementation .with .omega .3 .fatty .acids .are .sometimes .used .in .the .management .of .CF,
.results .from .clinical .trials .have .shown .mixed .results .and .further .trials .are .needed .to
.determine .the .efficacy .of .routine .EFA .supplementation .in .the .management .of .CF.
Which .of .the .following .is .the .best .choice .for .feeding .a .pancreatic .insufficient .infant .with
