Objective: To investigate the effect of CD8 CD28 T cells on acute graft-versus-host disease(aGVHD) after haploidentical hematopoietic stem cell transplantation(haplo-HSCT).

Methods: The relationship between absolute count of CD8 CD28 T cells and aGVHD in 60 patients with malignant hematological diseases was retrospectively analyzed after haplo-HSCT, and the differences in the incidence rate of chronic graft-versus host disease(cGVHD), infection and prognosis between different CD8 CD28 T absolute cells count groups were compared.

Results: aGVHD occurred in 40 of 60 patients after haplo-HSCT, with an incidence rate of 66.

Article Synopsis
  • The study investigates the use of F-FDG PET/CT imaging to diagnose bone marrow infiltration in patients with diffuse large B-cell lymphoma (DLBCL).
  • A total of 102 DLBCL patients were assessed with both PET/CT scans and bone marrow biopsies to determine the accuracy of PET/CT in detecting infiltration.
  • Results showed that PET/CT has high sensitivity and specificity for diagnosing bone marrow involvement in DLBCL, suggesting it can effectively guide biopsies and reduce misdiagnosis rates.

Background: There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China.

Methods: From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n  = 72) or allo-HSCT (n  = 56) at eight medical centers across China were included in this study.

Article Synopsis
  • The study investigates bloodstream infections in patients with hematological malignancies in the tropics, focusing on characteristics, prognosis, and risk factors to enhance prevention and treatment strategies.
  • The most common infection site is the lungs, with Gram-positive bacteria (primarily coagulase-negative staphylococci) being the most frequently detected pathogens, while Gram-negative bacteria (especially Klebsiella pneumoniae) show high resistance to certain antibiotics.
  • Septic shock is identified as a significant risk factor for 30-day mortality, while remission status is associated with better survival outcomes among these patients.

Article Synopsis
  • Long noncoding RNAs (lncRNAs) are increasingly recognized as crucial elements in molecular biology, influencing various biological processes like cell differentiation and tumor formation.
  • This review highlights the recent research on lncRNAs, focusing on their mechanisms and characteristics, especially concerning normal and malignant blood cell development (hematopoiesis).
  • The findings suggest that lncRNAs could be key players in gene regulation and may offer new opportunities for diagnosing and treating blood-related diseases in the future.

Article Synopsis
  • A systematic review analyzed the clinical benefits of single vs. double-unit umbilical cord blood transplantation (UCBT) in patients with blood diseases, revealing mixed results.
  • Although double-unit UCBT provided higher doses of certain cells, it did not improve hematologic recovery compared to single-unit UCBT.
  • Double-unit UCBT had higher rates of graft-vs-host disease but similar transplant-related mortality and survival rates, suggesting it may be beneficial for specific high-risk patients, warranting further study.

A meta-analysis of randomized controlled trials (RCTs) was conducted to evaluate the efficacy and safety of mesenchymal stromal cells (MSCs) for the prophylaxis of chronic graft-versus-host disease (cGVHD) in patients with hematological malignancies undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Six studies involving 365 patients were included. The pooled results showed that MSCs significantly reduced the incidence of cGVHD (risk ratio [RR] 0.

The abnormal activation of Notch signaling is closely related to the development of acute leukemia (AL). The core elements of the Notch signaling system include Notch receptors, Notch ligands, CSL DNA-binding proteins, and effectors like target genes. Any factors, which affect ligands, receptors, signal transducers and effectors, can influence the signal transduction of Notch signaling greatly.

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by increased platelet destruction and impaired platelet production. In this study, we conducted a systematic review and meta-analysis to determine the efficacy and safety of thrombopoietin receptor agonists (TPO-RAs) in primary ITP patients. Thirteen randomized controlled trials were included in this study, the pooled results of which demonstrated that TPO-RAs significantly increased platelet response (R) and durable response (DR) rates [risk ratio (RR): 2.
