“…The studies included groups of PN only [ 36 ], EN with PN [ 13 , 37 , 38 , 39 , 40 ], G-tube vs. NG-tube, or no feeding tube support [ 37 , 38 , 41 ], analyzing various nutritional and post-transplant parameters. Some patients received prophylactic G-tubes [ 37 , 38 , 41 ], others had NG-tubes placed by day + 1 [ 13 , 24 , 40 , 41 ], and others primarily relied on PN when the oral caloric intake was insufficient [ 36 , 39 , 42 ]. An alteration in nutritional support regimens was found to have an impact on the ability to meet energy requirements, as well as on various post-transplant outcomes, including length of stay (LOS), engraftment, overall survival (OS), and the incidence of acute GVHD (aGVHD), infection, and veno-occlusive disease (VOD).…”
