Despite the steady increase in the number of stem cell transplants performed since 1980 and improvements in survival rates, disease relapse remains the major cause of death after HLA matched sibling and unrelated donor transplants for acute myeloid leukemia (AML). Given this situation, maintenance therapy after transplant may be an appropriate strategy to reduce the relapse rate and prolong survival. A number of agents are being investigated as maintenance therapy after stem cell transplant in AML patients, including azacitidine, decitabine, and other agents. This paper focuses on the role of maintenance treatment to reduce the risk of relapse after transplant.

Background: Anaplastic thyroid cancer (ATC) is a highly lethal disease, often diagnosed with advanced locoregional and distant metastases, resulting in a median survival of just 3-5 months. This study determines the stratified effectiveness of baseline treatments in all combinations, enabling precise prognoses prediction and establishing benchmarks for advanced therapeutic options.
Methods: The study extracted a cohort of pathologically confirmed ATC patients from the Surveillance, Epidemiology, and End Results program.

Chronic Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT), affecting the female genital tract in 25-66% of the patients. This condition, referred to as Genital GVHD is an underdiagnosed gynecologic comorbidity, that can significantly impair quality of life. We aimed to describe the prevalence and management of genital GVHD following HSCT.

Intra-patient variability in immunosuppressive blood drug concentrations is a potential biomarker in managing organ transplant patients. However, the association between the time in therapeutic range of tacrolimus blood concentrations and its efficacy in preventing graft-versus-host disease remains unknown. In this study, we analyzed the relationship between the time in therapeutic range of tacrolimus blood concentrations and its efficacy in acute graft-versus-host disease prophylaxis in patients undergoing allogeneic hematopoietic stem cell transplantation.

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.

RAF protein kinases are major RAS effectors that function by phosphorylating MEK. Although all three RAF isoforms share a conserved RAS binding domain and bind to GTP-loaded RAS, only ARAF uniquely enhances RAS activity. Here we uncovered the molecular basis of ARAF in regulating RAS activation.
