This study tested two different chemotherapy drugs (Treosulfan and Busulfan) given before a stem cell transplant in 106 children with serious non-cancer diseases like immune disorders, metabolic diseases, blood disorders, and bone marrow failure. The goal was to see which drug le…

This study looked at 50 patients who needed a stem cell transplant from a partially matched donor but had antibodies that could attack the donor cells. Before transplant, they received a blood purification treatment called protein A immunoadsorption to remove those antibodies, so…

This study tested a new method called global metabolomic profiling to diagnose inborn errors of metabolism, a group of rare genetic disorders. Researchers compared this approach to traditional testing in 240 participants. The goal was to see if the new method could more accuratel…
