Summary: A new computational tool for flow cytometry diagnostics in suspected MDS patients was developed and prospectively validated in this study. The tool achieved high sensitivity and specificity in independent validation cohorts, outperforming conventional methods. The computational workflows show practical advantages and improved accuracy, objectivity, and time efficiency compared to expert-analyzed flow cytometry scores.

Summary: This study investigated the mechanism of decitabine resistance in the treatment of myelodysplastic syndrome (MDS). By establishing a drug-resistant cell line and conducting gene expression differential analysis, candidate genes associated with decitabine resistance were identified, with two genes being discovered to be related to poor prognosis. The study aims to develop a gene chip for diagnosing decitabine resistance in MDS patients.

Summary: The study validates the effectiveness of the Molecular International Prognostic Scoring System (IPSS-M) in predicting clinical outcomes of patients with myelodysplastic syndromes (MDS). IPSS-M improves the prognostic discrimination of the Revised International Prognostic Scoring System (IPSS-R) and enhances the accuracy of selecting candidates for hematopoietic stem cell transplantation (HSCT).

Summary: SF3B1 mutations define a distinct subgroup of MDS patients with favorable disease course and high response rates to luspatercept. This study identified immunophenotypic features associated with SF3B1 mutations and showed the impact of mutation type and co-occurrence with chromosome 5q deletion on bone marrow immunophenotype. These findings provide leads for refining prognostication and therapeutic strategies for this specific MDS subgroup.

Summary: WT1 expression levels in AML and MDS inversely correlated with normal hematopoiesis and were positively associated with blast counts. Flow cytometry was shown to be more sensitive and specific in distinguishing normal myeloid cells from neoplastic counterpart, even with just linear parameters and CD45 expression. A simple integrated approach combining blast counts by flow cytometry, FLT3 mutational status, and WT1 expression levels may provide a better prognostic definition for both AML and MDS patients.

Summary: The study revealed heterogeneous immune cell distribution in spatial proximity to CD34(+) blasts in MDS and sAML samples regardless of genetic alterations, but correlated to blast counts. CD8(+) and FOXP3(+) T cells were not found in the immediate vicinity of CD34(+) HPSC in control samples. The frequencies of immune cell subsets in MDS and sAML BMB differed from control BMB, providing new insights into immune deregulation.

Summary: The combination of metaphase cytogenetics analysis (MC) and single-nucleotide polymorphism arrays (SNP-A) karyotyping can improve the diagnostic yield and provide more precise prognostic stratification in patients with myelodysplastic syndromes (MDS). SNP-A can detect more chromosomal aberrations and copy number neutral loss of heterozygosity (CN-LOH). Factors such as age, bone marrow blasts, CN-LOH, new aberrations, TGA value, and IPSS-R risk score have prognostic significance in MDS.

Summary: Autologous stem cell transplantation (ASCT) is the standard treatment for younger patients with newly diagnosed multiple myeloma (MM). However, many eligible patients are excluded from transplant studies due to restrictive exclusion criteria. This retrospective analysis included 540 MM patients who received ASCT between 1996 and 2019.

Summary: The initial response criteria developed by the International Working Group (IWG) in 2000 have limitations in their application to higher-risk MDS and their ability to fully capture the clinical benefits of novel investigational drugs. Therefore, an international panel of MDS experts used a modified Delphi process to develop consensus recommendations for updated response criteria that would be more reflective of patient-centered and clinically relevant outcomes. The updated criteria should lead to a better correlation between patient-centered outcomes and clinical trial results.

Summary: This study aimed to describe sex diversity in myelodysplastic syndromes and incorporate sex information into clinical decision-making. The study found differences between men and women in terms of disease genotype, phenotype, and clinical outcomes. Moreover, new prognostic models that included sex information were developed and performed better than the revised International Prognostic Scoring System.

Summary: Type 1 diabetes mellitus (T1DM) is associated with increased bone fragility. Our study found accelerated osteocyte apoptosis and local mineralization in T1DM patients, suggesting that T1DM speeds up bone aging and impairs its biomechanical competence. Dysfunction of the osteocyte network hampers bone remodeling and repair, contributing to the increased fracture risk in T1DM individuals.

Summary: ASPIRE is a three-part international phase 2 trial that investigated the efficacy and safety of eltrombopag in patients with advanced myelodysplastic syndrome or acute myeloid leukemia and severe thrombocytopenia. The study found that approximately 30-65% of patients in the open-label extension phase experienced clinically relevant thrombocytopenic events. Long-term efficacy could not be determined due to the study design, and survival rates may be influenced by advanced disease. However, eltrombopag showed potential in treating thrombocytopenia in low-/intermediate-risk myelodysplastic syndrome patients, with consistent long-term safety results.

Summary: This study demonstrates that activation of the sympathetic nervous system through cold exposure or selective I33-adrenergic receptor agonist can alleviate the adverse metabolic effects caused by chronic glucocorticoid exposure. Cold exposure preserves the function of brown adipose tissue and reverses white adipose tissue lipid accumulation, correcting obesity, hyperinsulinemia, and hyperglycemia caused by glucocorticoids.

Summary: In low- and middle-income countries, including Ethiopia, access to standard diagnostic and prognostic tools for chronic myeloid leukemia (CML) is limited. This study found that multiplex PCR (mpx-PCR) can serve as a screening tool with high sensitivity and specificity, helping to rule out relapse and non-adherence to medications, thus reducing treatment risks.

Summary: Momelotinib is a first-in-class inhibitor of Janus kinases 1 and 2, as well as activin A receptor type 1, and has shown efficacy in addressing the symptoms of myelofibrosis, such as splenomegaly, constitutional symptoms, and anemia. This long-term analysis of pooled data from three phase 3 studies demonstrated the safety and tolerability of momelotinib, with no evidence of long-term or cumulative toxicity. The most common adverse events were diarrhea and hematologic abnormalities, but they were generally manageable. This analysis provides valuable evidence supporting the use of momelotinib in the treatment of myelofibrosis.

Summary: Osteocytes, senescent cells implicated in bone loss disorders, have been shown to be effectively cleared through systemic senolysis, preventing age-related bone loss and mitigating bone marrow adiposity. Cell-specific senolysis in osteocytes alone had only a partial effect. Surprisingly, transplantation of senescent fibroblasts into young mice led to osteocyte senescence and bone loss. These findings on osteocyte senescence and the effects of remote senolysis suggest potential strategies against multisystem aging.
