bacteremia in adult patients with hematological diseases: clinical characteristics and risk factors for 28-day mortality.

Patients with hematological diseases are at high risk for (SM) bacteremia. This study retrospectively analyzed the clinical characteristics and risk factors for 28-day mortality among 140 adult hematological patients diagnosed with SM bacteremia from January 2012 to July 2023. he overall 28-day mortality was 31.

Clinical data and MRI features-based nomogram for differentiation of central nervous system infection and central nervous system involvement in hematological malignancy.

Central nervous system leukemia (CNSL) and central nervous system infection (CNSI) are the most important complications in patients with acute leukemia (AL). However, the differential diagnosis could represent a major challenge since the two disorders are all heterogeneous entities with overlapping clinical characteristics and radiological appearances. In this paper, we conduct a retrospective study to develop a model based on clinical data and magnetic resonance imaging (MRI) to distinguish CNSL from CNSI.

Impact of platelet transfusion refractoriness in the first 30 days post-hematopoietic stem cell transplantation on outcomes of patients with myelodysplastic syndrome.

Introduction: Currently, no study has determined whether platelet transfusion refractoriness (PTR) post-hematopoietic stem cell transplantation (HSCT) before engraftment in patients with myelodysplastic syndrome (MDS) would impacts clinical outcomes.

Methods: We performed a MDS-specific retrospective analysis to determine whether PTR in one-month post-HSCT in patients with MDS could influence outcomes.

Results And Discussion: Among the 315 patients enrolled, 110 (34.

Impact of bone marrow fibrosis on outcomes of allogeneic hematopoietic stem cell transplantation in acute myeloid leukemia.

Bone marrow fibrosis (BMF) of unknown etiology was common in hematological malignancies, but its prognostic value for acute myeloid leukemia (AML) is unclear. We interrogated data from 532 newly diagnosed subjects with AML receiving allogeneic hematological stem cell transplantation to evaluate the prognostic impact of BMF on transplant outcomes. Using the European consensus on the grading of BMF at diagnosis, 255 (48%) subjects were BMF-0, 209 (39%), BMF-1 and 68 (13%), BMF-2-3.

Application patterns and outcomes of hematopoietic stem cell transplantation in peripheral T-cell lymphoma patients: a multicenter real-world study in China.

The optimal timing and type of hematopoietic stem cell transplantation (HSCT) for treating peripheral T-cell lymphoma (PTCL) remain controversial. This retrospective real-world study investigated the application pattern and outcomes of HSCT in China. The analysis encompassed 408 PTCL patients with a median age of 45.

Clinical Characteristics, Prognosis Factors and Metagenomic Next-Generation Sequencing Diagnosis of Mucormycosis in patients With Hematologic Diseases.

Introduction: New diagnostic methods and antifungal strategies may improve prognosis of mucormycosis. We describe the diagnostic value of metagenomic next⁃generation sequencing (mNGS) and identify the prognostic factors of mucormycosis.

Methods: We conducted a retrospective study of hematologic patients suffered from mucormycosis and treated with monotherapy [amphotericin B (AmB) or posaconazole] or combination therapy (AmB and posaconazole).

The impact of the donors' COVID-19 status on the outcomes of allogeneic hematopoietic stem cell transplantation: a multi-center retrospective study.

Introduction: To explore the impact of donors' COVID-19 status on allogeneic stem cell transplantation (allo-HSCT), we compared the transplant outcomes of 74 participants.

Methods: This multi-center retrospective study included nine participants receiving grafts from COVID-19 positive donors (CPD), 45 from COVID-19 experienced donors (CED), and 20 from COVID-19 naive donors (CND). We evaluated engraftment, complications, and survival rates among the three groups.

Posaconazole gastro-resistant tablets for preventing invasive fungal disease after haematopoietic stem cell transplantation: a propensity-matched cohort study.

Objectives: To evaluate posaconazole (POS) gastro-resistant tablets for preventing invasive fungal disease (IFD) in haematopoietic stem cell transplantation (HSCT) patients and analyse POS plasma concentrations.

Methods: A single-arm trial was designed with a historical cohort as a control. Patients aged 13 years and older undergoing HSCT at the HSCT Center of Blood Diseases Hospital, Chinese Academy of Medical Sciences between December 2020 and May 2022 were enrolled, prospectively taking POS gastro-resistant tablets orally from day 1 to day 90 post-transplant and monitoring plasma concentrations.

C-JUN overexpressing CAR-T cells in acute myeloid leukemia: preclinical characterization and phase I trial.

Chimeric antigen receptor (CAR) T cells show suboptimal efficacy in acute myeloid leukemia (AML). We find that CAR T cells exposed to myeloid leukemia show impaired activation and cytolytic function, accompanied by impaired antigen receptor downstream calcium, ZAP70, ERK, and C-JUN signaling, compared to those exposed to B-cell leukemia. These defects are caused in part by the high expression of CD155 by AML.

WT1 gene mutations impact post-transplant relapse in myelodysplastic syndrome with excess blasts 2 patients.

Wilms tumor 1 (WT1) gene mutations are infrequent in myelodysplastic syndrome (MDS), but MDS with WT1 mutations (WT1) is considered high risk for acute myeloid leukemia (AML) transformation. The influence of WT1 mutations in patients with MDS after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is unclear. We performed a retrospective analysis of 136 MDS with excess blasts 2 (MDS-EB2) patients with available WT1 status who underwent their first allo-HSCT between 2017 and 2022 in our center.

Prophylactic therapy using epigenetic agents for RUNX1::RUNXT1-positive high-risk AML after Allo-HSCT.

Disease recurrence is the leading cause of treatment failure in patients with RUNX1::RUNXT1-positive acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Post-transplant maintenance therapy, guided by monitoring minimal residual disease (MRD), is commonly administered; however, relapse rates remain high. This prospective study aimed to assess the effectiveness and safety of epigenetic agents as prophylactic therapy in patients with RUNX1::RUNXT1-positive AML.

Strong Homology Between Colonizing and Bloodstream Carbapenem-Resistant Spp.: Implications for Empiric Antibiotic Therapy in Hematological Patients.

Objective: This study aimed to assess the impact of colonization status on the outcomes of spp. bloodstream infection (BSI) and investigate the homology and within-host evolution between colonizing and bloodstream carbapenem-resistant spp. (CRA) to inform antibiotic therapeutic decisions.

Combining serum microRNAs and machine learning algorithms for diagnosing infectious fever after HSCT.

Infection post-hematopoietic stem cell transplantation (HSCT) is one of the main causes of patient mortality. Fever is the most crucial clinical symptom indicating infection. However, current microbial detection methods are limited.

An investigation of the immune epitopes of adeno-associated virus capsid-derived peptides among hemophilia patients.

Adeno-associated virus (AAV) is an optimal gene vector for monogenic disorders. However, neutralizing antibodies (Nabs) against AAV hinder its widespread application in gene therapy. In this study, we biosynthesized peptides recognized by the binding antibodies (Babs) from the sera containing high Nab titers against AAV2.

Ursodeoxycholic acid does not reduce SARS-CoV-2 infection in newly allogeneic hematopoietic stem cell transplantation recipients: a prospective NICHE cohort.

Introduction: Retrospective studies have suggested that Ursodeoxycholic Acid (UDCA) provide a protective effect against SARS-CoV-2 infection, particularly in patients with liver disease. However, it is uncertain whether this finding can be extended to the allogeneic hematopoietic stem cell transplantation (allo-HSCT) cohort. Therefore, we aim to examine the protective potential of UDCA against SARS-CoV-2 infection in recently received allo-HSCT patients.

Exploring strategies to optimise outcomes in hepatitis-associated aplastic anaemia patients following haematopoietic stem cell transplantation.

This study aimed to assess haematopoietic stem cell transplantation (HSCT) safety and efficacy while exploring strategies for optimising outcomes in patients with hepatitis-associated aplastic anaemia (HAAA). We retrospectively reviewed 35 HAAA patients who underwent HSCT at a large Chinese blood disease hospital between 2008 and 2022. HAAA patients receiving HSCT typically presented with severe (28.
