Jumping translocation of 3q21 in a patient with acute myeloid leukemia and poor clinical outcome.

Jumping translocation (JT) is a cytogenetic event in which a donor chromosomal segment is translocated to two or more recipient chromosomes. We describe a case of a 75-year-old female patient diagnosed with acute myeloid leukemia (AML) with monocytic differentiation having acquired JT involving 3q21→3qter as a donor chromosomal segment with 12 different recipient chromosomes. Each abnormal clone had monosomy 7 and trisomy 8.

Dissimilar ferric derisomaltose formulations - In vitro comparisons between an originator and its intended similars.

Background: The complex nature of intravenous (IV) iron formulations makes manufacturing and characterising similars challenging. This study examined whether simple in vitro tests can distinguish the high-dose IV iron formulation, Monofer® (ferric derisomaltose [FDI]), from the first intended copies of FDI, Rapifer® (FDI intended similar A [FDIIS-A]) and Tosiron® (FDI intended similar B [FDIIS-B]), approved in India and Pakistan, respectively. Neither intended similar is available in Europe or the United States.

Immune reconstitution following umbilical cord blood transplantation: IRES, a study of UK paediatric patients.

To obtain a qualitative as well as quantitative view immune reconstitution following umbilical cord blood (UCB) transplantation of paediatric patients, we utilised a broad panel of flow cytometry markers to monitor the phenotypes of lymphoid and myeloid cells at 1-12 months post-transplant. Samples were received from 46 patients with a median age of 3.3 years and survival was 76% at 1 year.

Subsequent donation requests among 2472 unrelated hematopoietic progenitor cell donors are associated with bone marrow harvest.

Approximately 1 in 20 unrelated donors are asked to make a second donation of hematopoietic progenitor cells, the majority for the same patient. Anthony Nolan undertook a study of subsequent hematopoietic progenitor cell donations made by its donors from 2005 to 2011, with the aims of predicting those donors more likely to be called for a second donation, assessing rates of serious adverse reactions and examining harvest yields. This was not a study of factors predictive of second allografts.
