NUP98 Rearrangement Dynamics Predict Outcomes in Adult Patients With Acute Myeloid Leukemia Undergoing Allogeneic Hematopoietic Stem Cell Transplantation: A Multicenter Real-World Study.

Background: Acute myeloid leukemia with NUP98 rearrangements (NUP98r) is associated with poor prognosis, and while allo-HSCT remains the primary curative approach, its efficacy in NUP98r patients is still uncertain. The prognostic impact of NUP98 fusion partners, accompanying genetic alterations, and NUP98r dynamics is unclear.

Methods: We retrospectively analyzed 56 adult patients with NUP98r AML undergoing allo-HSCT across multiple centers.

Changing donors improves outcomes of second transplantation in patients who experienced graft failure after first allogeneic stem cell transplantation.

A second transplantation is almost the only salvage for patients encountering graft failure (GF) following the first allogeneic stem cell transplantation. However, there were no standard protocols for second transplantations, and the role of changing donors remained controversial. We retrospectively studied 272 consecutive patients from 18 Chinese centers undergoing second transplantations due to GF, aiming to assess the impact of changing donors and factors affecting second transplantation outcomes.

Decoding the immune microenvironment of secondary chronic myelomonocytic leukemia due to diffuse large B-cell lymphoma with CD19 CAR-T failure by single-cell RNA-sequencing.

Background: Several studies have demonstrated the occurrence of secondary tumors as a rare but significant complication of chimeric antigen receptor T (CAR-T) cell therapy, underscoring the need for a detailed investigation. Given the limited variety of secondary tumor types reported to date, a comprehensive characterization of the various secondary tumors arising after CAR-T therapy is essential to understand the associated risks and to define the role of the immune microenvironment in malignant transformation. This study aims to characterize the immune microenvironment of a newly identified secondary tumor post-CAR-T therapy, to clarify its pathogenesis and potential therapeutic targets.

IgG N-glycosylation contributes to different severities of insulin resistance: implications for 3P medical approaches.

Background: Reliable biomarkers capturing immunometabolic processes in insulin resistance (IR) remain limited. IgG N-glycosylation modulates immune responses and reflects metabolic disorders, yet its role in IR remains unclear. This study investigated its potential for early detection, risk stratification, and targeted prevention within the framework of predictive, preventive, and personalised medicine (PPPM/3PM).

Structure-Activity Relationship in PtCo L10 Ordered Phase ORR Catalysts: Pt-Rich Shell Having Anisotropic Lattice Distortion Revealed by PDF and XAS Analysis.

Ordered intermetallic PtCo alloys are promising candidates for next-generation low-Pt catalysts in proton exchange membrane fuel cells (PEMFCs) due to their high activity and stability originating from ligand and strain effects. However, the influence of the ordered phase on the surface structure, especially after Pt-rich shell formation, remains poorly understood. In this study, we systematically investigated the structural and electrochemical properties of PtCo catalysts with varying degrees of ordering, prepared by controlling the annealing temperature and time.

A Population Pharmacokinetics Study of Venetoclax Concomitant with Voriconazole in Patients with Hematologic Malignancies.

Background: Venetoclax is a selective small-molecule BCL-2 inhibitor that has been approved for treating hematologic malignancies. Co-administration with CYP3A inhibitors, such as voriconazole, poses a high risk of drug-drug interactions (DDIs) that can increase venetoclax exposure. This study aimed to develop a population pharmacokinetics (PopPK) model to characterize the PK properties of venetoclax when co-administered with voriconazole.

Bispecific antibodies in immunotherapy for acute leukemia: latest updates from the 66th annual meeting of the American society of hematology, 2024.

Bispecific antibodies (BsAbs) are cutting-edge immunotherapy agents that can bind two distinct antigens or epitopes simultaneously. They hold significant potential in targeting leukemic cell markers and activating immune cells like T cells or NK cells to eliminate malignant cells. BsAb treatments showed encouraging outcomes for both acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL).

Summarizing attributable factors and evaluating risk of bias of Mendelian randomization studies for Alzheimer's dementia and cognitive status: a systematic review and meta-analysis.

Background: No effective treatment is available to delay or reverse the onset and progression of Alzheimer's dementia (AD). Mild cognitive impairment, a clinical state between normal aging and AD, may offer the proper window for AD intervention and treatment. This systematic review aimed to summarize evidence from Mendelian randomization (MR) studies exploring factors attributable to AD and related cognitive status and to assess its credibility.

Modifiable factors for irritable bowel syndrome: evidence from Mendelian randomisation approach.

Background: The potential modifiable factors influencing irritable bowel syndrome (IBS) have not been thoroughly documented. We aimed to systematically investigate the modifiable factors associated with IBS, while accounting for the impact of unobserved confounders and coexisting disorders.

Methods: Genetic correlation and Mendelian randomisation (MR) analyses were integrated to identify potential modifiable factors and coexisting disorders linked to IBS.

The role of lncRNA NEAT1 in acute graft-versus-host disease: Regulation of macrophage polarization and inflammatory cytokine secretion via JNK/NLRP3 pathway.

Background: Acute graft-versus-host disease (aGVHD) is a complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). The role of macrophages as proficient antigen-presenting cells in aGVHD is a prominent area of investigation in contemporary research. The association between long noncoding RNA nuclear enriched abundant transcript 1 (lncRNA NEAT1) and the macrophage function is of significant interest.

Systems biology and multiomics research expand the prospects of planetary health innovations. In this context, this mini-review unpacks the twin scholarships of glycomedicine and precision medicine in the current era of single-cell multiomics. A significant growth in glycan research has been observed over the past decade, unveiling and establishing co- and post-translational modifications as dynamic indicators of both pathological and physiological conditions.

CD7-positive leukemic blasts with mutations predict poor prognosis in patients with acute myeloid leukemia.

Background: mutations can be detected in premalignant hematopoietic stem cells and are primarily associated with clonal hematopoiesis of indeterminate potential; however, current evidence does not support assigning them to a distinct European Leukemia Net (ELN) prognostic risk stratification. CD7 is a lymphoid antigen expressed on blasts in approximately 30% of acute myeloid leukemia (AML), and its role in AML remains unclear and depends on subgroup evaluation. This study investigated the prognostic value of mutation combined with CD7 expression in AML.

Association between inflammatory bowel disease and cancer risk: evidence triangulation from genetic correlation, Mendelian randomization, and colocalization analyses across East Asian and European populations.

Background: Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), has been associated with several cancer risks in observational studies, but the observed associations have been inconsistent and may face the bias of confounding and reverse causality. The potential causal relationships between IBD and the risk of cancers remain largely unclear.

Methods: We performed genome-wide linkage disequilibrium score regression (LDSC), standard two-sample Mendelian randomization (MR), and colocalization analyses using summary genome-wide association study (GWAS) data across East Asian and European populations to evaluate the causal relationships between IBD and cancers.

Bispecific antibodies in immunotherapy for adult acute leukemia: latest updates from the 65th American Society of Hematology 2023 Annual Meeting.

Introduction Bispecific antibodies (BsAbs) represent a novel and potentially effective approach in cancer immunotherapy. These antibodies feature two unique binding domains, enabling them to simultaneously attach to two antigens or two epitopes of a single antigen. Recently, a variety of BsAbs targeting distinct B-cell antigens and myeloid lineage-specific surface markers-such as CD19xCD3, CD38xCD3, and CD123xCD3-have demonstrated promising results in heavily pretreated relapsed/refractory acute lymphoblastic leukemia (R/R ALL) and relapsed/refractory acute myeloid leukemia (R/R AML) patients.

Investigating Degradation Mechanisms in PtCo Alloy Catalysts: The Role of Co Content and a Pt-Rich Shell Using High-Energy Resolution Fluorescence Detection X-ray Absorption Spectroscopy.

Low Pt-based alloy catalysts are regarded as an efficient strategy in achieving high activity for the oxygen reduction reaction (ORR) in proton-exchange membrane fuel cells (PEMFCs). However, the desired durability for the low Pt-based catalysts, such as the PtCo catalyst, has still been considered a great challenge for PEMFCs. In this study, we investigate sub-2.

Comparative analysis of hypomethylating agents as maintenance therapy after allogeneic hematopoietic stem cell transplantation for high-risk acute leukemia.

We retrospectively analyzed the outcomes of 136 consecutive patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) at our center. Among them, 76 cases used hypomethylating agents (decitabine,  = 40; azacitidine,  = 36) as post-transplant maintenance therapy, whereas 60 contemporaneous patients did not adopt maintenance therapy. The 3-year incidences of relapse in two groups were 16.
