The clinical features, risk factors and outcomes of polyomavirus encephalitis after allogeneic haematological stem cell transplantation.

Polyomavirus (PyV) encephalitis is a rare but life-threatening opportunistic infection linked to progressive multifocal leucoencephalopathy (PML). We analysed 54 patients diagnosed with PyV encephalitis after allogeneic haematopoietic stem cell transplantation (allo-HSCT) in a 1:4 case-control retrospective cohort study. Median time to diagnosis was 77 days post-HSCT, with seizures, headache and motor dysfunction as the most common presenting symptoms.

Visual analysis of research trends in diabetes-associated dry eye bibliometrics.

Aim: To provide a comprehensive review of the advances in research on diabetes-associated dry eye (DADE), highlighting its pathophysiological mechanisms, risk factors, and demographic characteristics, laying the foundation for further investigation into its pathogenesis and treatment strategies.

Methods: A systemic review of the documents related to DADE had been performed based on the Web of Science database prior to achieving the plain text files of authors, titles, journals, and abstracts which afterwards had been imported into Citespace and VOSviewer software for data cleansing. The visual analysis was implemented from the following aspects: journals' publications, author and national cooperation, keyword co-occurrence, timeline analysis, and burst detection.

Behavioural response and physiological adaptation of captive sub-adult giant pandas in response to a short-term social environment.

During ex-situ conservation, giant pandas inevitably transition from their natural wild habitats to captive environments. The living conditions of captive giant pandas differ significantly from those in the wild. For instance, during the sub-adult stage, solitary giant pandas are human-reared in groups.

Long-term efficacy of EBV-specific T cells for EBV-PTLD after allogeneic stem cell transplantation: a real word study.

Background: Epstein-Barr virus-associated post-transplant lymphoproliferative disorder (EBV-PTLD) remains a life-threatening complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), especially in rituximab-refractory cases. Adoptive transfer of EBV-specific cytotoxic T lymphocytes (EBV-CTLs) offers a promising strategy to restore antiviral immunity, but long-term efficacy data, particularly in haploidentical transplant recipients, remain limited.

Methods: We conducted a retrospective study of 41 haploidentical HSCT recipients diagnosed with EBV-PTLD and received donor-derived EBV-CTLs.

Viral enteritis after allogeneic hematopoietic stem cell transplantation: pathogens, clinical characteristics, and outcomes.

Viral enteritis is a common complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, data regarding the most frequent enteric pathogens, clinical characteristics, and patient outcomes remains limited. To better characterize post-HSCT viral enteritis, we retrospectively analyzed 59 patients who underwent allo-HSCT and were diagnosised with viral enteritis based on intestinal biopsy specimens.

Leukemia stem cells for relapse prediction in AML patients receiving allografts: long-term follow-up of a prospective study.

In this study, we explored the ability of leukemia stem cell (LSC)-based method and traditional multiparameter flow cytometry (MFC) assay to predict leukemia relapse after long-term follow-up. 360 AML patients who received allografts between July 2018 and November 2019 were prospectively enrolled. Patients with positive measurable residual disease (MRD) based on CD34CD38cocktail LSCs (≥0.

Peritransplant lysine methyltransferase 2a-rearranged measurable residual disease dynamics as a prognostic marker in adult acute myeloid leukemia.

Background: This study examined the impact of measurable residual disease (MRD) dynamics in adults with lysine methyltransferase 2a rearrangement (KMT2Ar) in acute myeloid leukemia (AML) during the peritransplant period (before and early after allogeneic hematopoietic stem cell transplantation [HSCT]).

Methods: This study involved 144 adult patients with AML with KMT2Ar who underwent HSCT between 2015 and 2024. Patients were enrolled if they survived without relapse for at least 3 months post-HSCT.

The Impact of Blast Percentage on Posttransplant Outcomes of Patients With Myelodysplastic Syndromes: A Retrospective Analysis Within the IPSS-M Framework.

Background: Blast percentage is crucial for myelodysplastic syndrome (MDS) diagnosis and risk stratification, but its role is now less prominent due to comprehensive genetic-based scoring systems like the Molecular International Prognostic Scoring System (IPSS-M). Originally, blast percentage was an independent categorical variable for prognosis, but in the IPSS-M, it is treated as a continuous variable. We hypothesize that blast percentage should still hold categorical value within genetic-based systems like the IPSS-M, especially for predicting transplant outcomes.

Incidence, Risk Factors, and Impact on Transplant Outcomes of Cytokine Release Syndrome After Infusion of Haploidentical Stem Cells With Anti-Thymocyte Globulin.

Background: Cytokine release syndrome (CRS) after graft infusion under anti-thymocyte globulin (ATG)-based haploidentical (haplo)-hematopoietic stem cell transplantation is unclear.

Objective: The purpose of this study was to explore the clinical implications of CRS after graft infusion under ATG-based haplo-SCT.

Study Design: We retrospectively analyzed the data of 259 patients who underwent haplo-SCT, graded CRS, and evaluated transplant outcomes.

Characteristics and prognosis of central nervous system relapse after allogeneic hematopoietic stem cell transplantation in adult patients with leukemia.

Central nervous system(CNS) is a common site of extramedullary involvement after allogeneic hematopoietic stem cell transplantation(allo-HSCT). It may confer inferior survival when combined with bone marrow(BM) relapse in leukemia patients. We performed a retrospective study to investigate the associated risk factors and prognosis in adult patients with post-transplant CNS relapse.

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.

Clinical Effects of RUNX1 Mutations on the Outcomes of Patients with Acute Myeloid Leukemia Treated with Allogeneic Hematopoietic Stem-Cell Transplantation.

It is reported that AML with RUNX1 mutations is associated with poorer response to conventional chemotherapy, lower rates of complete remission (CR), leukemia-free survival (LFS), and overall survival (OS). We aimed to evaluate the prognostic impact of RUNX1 mutations following allogeneic hematopoietic stem cell transplantation (allo-HSCT) by comparing clinical outcomes in AML patients with and without RUNX1 mutations. We retrospectively analyzed 91 AML patients (33 RUNX1+ and 58 RUNX1-) who received their first HSCT at Peking University People's Hospital.

Randomized trial of anti-thymocyte globulin plus low-dose post-transplant cyclophosphamide to prevent graft-versus-host disease in haploidentical transplantation.

The combination of anti-thymocyte globulin (ATG) and posttransplant cyclophosphamide (PTCy) appears to be a potentially effective graft-versus-host disease (GVHD) prevention strategy for haploidentical transplantation. However, the majority of the evidence originated from retrospective studies without uniform protocols. Our previous findings indicated that 10 mg/kg ATG plus low-dose PTCy could decrease GVHD among high-risk populations transplanted from maternal or collateral relatives.

Comparative chloroplast genome analyses of potentilleae: insights into genome characteristics, mutational hotspots, and adaptive evolution.

PD-1 inhibitor in patients with minimal residual disease who failed donor lymphocyte infusion or interferon after allogeneic haematopoietic stem cell transplantation.

This study aimed to evaluate the efficacy and safety of programmed death receptor 1 (PD-1) antibody in patients with acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) with minimal residual disease (MRD) after allogeneic haematopoietic stem cell transplantation (allo-HSCT). Six patients were retrospectively reviewed in this study, and all had failed prior treatment (donor lymphocyte infusion or interferon) before PD-1 antibody administration. Among these 6 patients, two received PD-1 alone while four received PD-1 plus azacitidine.

The outcomes of second haploidentical donor transplantation for graft failure in patients with severe aplastic anaemia.

This study aimed to evaluate the outcomes of second haploidentical hematopoietic stem cell transplantation (HID-HSCT) for patients with severe aplastic anaemia (SAA) who experienced graft failure. Twenty-one SAA patients with graft failure after first allogeneic (allo-) HSCT were enrolled, including 6 (28.6%) with poor graft function and 15 (71.

Metagenomic Next-generation Sequencing Compared With Blood Culture as First-line Diagnostic Method for Bloodstream Infection in Hematologic Patients With Febrile Neutropenia: A Multicenter, Prospective Study.

Bloodstream infection (BSI) is a frequent but lethal complication in hematologic patients with febrile neutropenia (FN). However, blood culture (BC) only detects an organism in 20%-30% of patients with FN. We aimed to evaluate the diagnostic performance of metagenomic next-generation sequencing (mNGS) as a first-line diagnostic method in BSI.

Assessment of the respiratory chain enzyme activity in peripheral blood monocytes for the noninvasive diagnostics of mitochondrial disease.

Background: Mitochondrial diseases are among the most common metabolic disorders caused by mitochondrial dysfunction. Analyzing mitochondrial respiratory chain enzyme activity is essential for diagnosis. However, clinical laboratories often rely on mitochondria isolated from muscle biopsies or cultured skin fibroblasts, which may be unacceptable for some pediatric patients.

Prognostic value of CEBPA bZIP signatures in cytogenetically normal acute myeloid leukaemia.

Recent studies revealed that CEBPA with basic leucine zipper (bZIP) in-frame mutation (CEBPA) is the bona fide entity with a favourable prognosis in acute myeloid leukaemia. However, the mechanism by which the bZIP signatures influence risk stratification remains unclear. We identified 141 patients with CEBPA.

Comparison of outcomes between haploidentical and matched related donors for chronic myelomonocytic leukemia: A multicenter real-world study.

Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative strategy for patients with chronic myelomonocytic leukemia (CMML). However, few reports have investigated the outcomes of patients receiving haploidentical HSCT. To this end, we included 117 patients with haploidentical donors (HID) and 75 patients with matched related donors (MRD) from 28 centers across China to explore the prognostic impact of different transplantation modalities.

N-acetyl-L-cysteine promoted hematopoietic recovery in patients with acute myeloid leukemia after complete remission--A pilot study.

Chemotherapy is a cornerstone treatment for acute leukemia (AL), but it often results in bone marrow (BM) failure, leading to infections, anemia, and bleeding, which significantly impact patient survival. Endothelial progenitor cells (EPCs) are critical elements of the BM microenvironment and are essential for hematopoiesis. Our previous research using in vitro and AML mouse models indicated that BM EPC dysfunction, characterized by impaired angiogenesis and elevated reactive oxygen species (ROS) levels in AML patients, could be partially reversed after complete remission (CR) and further improved with N-acetyl-L-cysteine (NAC) treatment.

Generation of an induced pluripotent stem cell line BIOi004-A from a patient with autosomal dominant retinitis pigmentosa.

RP33 is a form of autosomal dominant retinitis pigmentosa (adRP), which is caused by heterozygous variants in the SNRNP200 gene. Peripheral blood mononuclear cells (PBMCs) were isolated from a 31-year-old Chinese patient with a heterozygous c.2359G > A variant in the SNRNP200 gene.

Age-stratified associations between radiotherapy and SPMs for FPHNC: a population-based cohort study.

Background: Second primary malignancies (SPMs) account for over 30% of total deaths in head and neck cancer (HNC) patients. The increasing use of radiotherapy raises concerns about the elevated risk of radiation-associated SPMs. This study aimed to investigate the age-stratified association between radiotherapy and SPM risk in survivors of non-metastatic primary HNC.
