Summary: In this study, a dual-functional Ce-based metal-organic framework@polydopamine (Ce-MOF@PDA) composite was designed and evaluated for treating iron overload (IO) and oxidative stress injury caused by β-thalassemia. Ce-MOF@PDA showed the ability to scavenge reactive oxygen species (ROS) and eliminate iron overload, reducing tissue damage caused by oxidative stress. The results suggest that Ce-MOF@PDA nanozyme is a promising therapeutic nanomedicine for treating thalassemia IO.

Summary: The aim of this study was to develop new strategies to prevent or reduce organ damage caused by iron-mediated oxidation in thalassemia major patients. Blood samples were taken from 70 patients before and after transfusion and various biomarkers related to oxidation and antioxidant defense were measured. The results showed that transfusion therapy increased both oxidation and antioxidant levels. Additionally, a new parameter called undepleted thiol level was introduced to assess the potential organ damage caused by oxidation in transfusion-dependent thalassemia patients.

Summary: The study identifies an association between three iron-related miRNAs and tissue iron overload in transfusion-dependent beta-thalassemia major patients. Results suggest that circulating miR-let-7d and miR-200b are downregulated, while miR-122 is upregulated in TDT patients. Aberrant expression of miRNAs is significantly associated with increased iron accumulation in hepatic and cardiac tissues, making them potential predictive biomarkers for tissue iron excess.

Summary: Assessing minimal residual disease (MRD) is crucial for risk classification and personalized therapy in childhood acute lymphoblastic leukemia (ALL). A study in Turkey retrospectively collected data of pediatric ALL patients treated with Berlin-Frankfurt-Munster (BFM) protocols. MRD assessment was done using real-time quantitative polymerase chain reaction (qPCR) and multiparametric flow cytometry (MFC). MRD monitoring led to upgrading 2% of patients from intermediate risk group to high-risk group. Factors such as age ≥10 years, poor response to prednisone, PCR-MRD ≥10(-3) on day 33 and day 78 were identified as poor prognostic factors affecting event-free survival (EFS). Establishing infrastructure and ensuring standardization for MRD methods are crucial for optimal management of children with ALL.

Summary: This study is the first to investigate the prognostic role of cytokines and sHLA-G levels in pediatric leukemia patients who have undergone allo-SCT. The study found that the levels of all cytokines tested and sHLA-G were significantly higher at diagnosis and at the post-transplant time points compared to the pre-transplantation period. Elevated IL-4, IL-10, and/or sHLA-G at diagnosis and post-transplantation (specifically at day 14) were associated with higher relapse rates, while elevated IL-2 and TNF-alpha at the time of transplantation were associated with lower survival rates. Serum cytokines and sHLA-G levels may serve as useful predictors of survival and relapse in these patients.

Summary: Relapse after allo-HSCT remains a common cause of post-transplantation mortality. Isolated extramedullary relapse (iEMR) is relatively rare, with CR2+/active disease at transplantation and prior EM disease as independent risk factors for iEMR. The prognosis of iEMR is poor, especially after a second relapse, highlighting the need for improved strategies to enhance outcomes.
