This study analyzed recent changes in the utilization of allogeneic hematopoietic cell transplantation (HCT) for treatment of acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and myeloproliferative diseases (MPDs) and the survival of HCT recipients ≥60 years of age in Brazil. This retrospective registry study included patients who received a first allogeneic HCT from any donor between 2012 and 2023. Of the 6657 patients, 444 (7%) were 60 years of age or older who received grafts from human leukocyte antigen (HLA)-matched related (42%) or unrelated (20%) donors or HLA-haploidentical donors (32%).

Article Synopsis
  • Exposure to organophosphorus compounds, like chlorpyrifos (CPF), can lead to various health issues affecting the brain and heart, primarily due to the inhibition of the enzyme acetylcholinesterase (AChE).
  • In a study on rats, intermittent CPF treatment was found to increase anxiety and impair motor functions, but it did not significantly affect depression symptoms or fear responses after a washout period.
  • Measurement of AChE activity showed significant reductions in key brain areas, indicating a link between CPF exposure and neurotoxicity, particularly at higher doses.

Changes in temperature and the deposition of potential pollutants in the soil, such as heavy metals, may damage plant communities, altering their physiological processes. High temperature may also cause a series of morpho-anatomical, physiological and biochemical changes in plants. However, tolerant plant species tend to restrict these harmful effects.

Autologous hematopoietic stem cell transplantation (Auto-HSCT) is widely used in the treatment of patients with hematological neoplasms. Since these cells circulate in small quantities in the periphery, the use of regimens that promote their mobilization is essential. In this study, we retrospectively evaluated the efficacy and safety of using intermediate doses of cytarabine (1.

The secretome present in the conditioned medium (CM) of mesenchymal stem cells (MSCs) is a promising tool to be used in therapies to promote bone regeneration. Considering the high osteogenic potential of the bone morphogenetic protein 9 (BMP-9), we hypothesized that the secretome of MSCs overexpressing BMP-9 (MSCs ) enhances the osteoblast differentiation of MSCs and the bone formation in calvarial defects. CM of either MSCs (CM-MSCs ) or MSCs without BMP-9 overexpression (CM-MSCs ) were obtained at different periods.
