Outcomes of allogeneic stem cell transplant in adult Philadelphia negative acute lymphoblastic leukemia patients treated with the pediatric-inspired GIMEMA 1913 protocol. A Campus ALL study.

Allogeneic hematopoietic stem cell transplantation (alloHSCT) is the best consolidative treatment for high-risk acute lymphoblastic leukemia (ALL). The Campus ALL study group analyzed the clinical outcomes of patients treated in the real-life with the pediatric-inspired and minimal/measurable residual disease (MRD)-oriented GIMEMA LAL1913 protocol who underwent alloHSCT. Key factors impacting on outcomes were MRD and remission status (1 complete remission vs 2 complete remission) at transplant.

Formation of the black-hole binary M33 X-7 through mass exchange in a tight massive system.

The X-ray source M33 X-7 in the nearby galaxy Messier 33 is among the most massive X-ray binary stellar systems known, hosting a rapidly spinning, 15.65M(⊙) black hole orbiting an underluminous, 70M(⊙) main-sequence companion in a slightly eccentric 3.45-day orbit (M(⊙), solar mass).
