Background: Clinical data suggest that autologous blood donation may prevent postsurgical venous thrombosis. If confirmed, this is probably due to beneficial effects in rheologic and hematologic variables which may be changed in patients as a result of repeated bleeding.
Study Design And Methods: To ascertain this point, we studied variations in hematological, hemorheological, coagulative and fibrinolytic parameters in 30 patients undergoing autologous blood donation.
Results: Whole blood viscosity (WBV), plasma viscosity and blood viscosity adjusted to 40% hematocrit, progressively and substantially decreased throughout the successive bleeding at all the shear rates considered. WBV was further reduced by presurgical hemodilution with autologous plasma which decreased the platelet and leukocyte count. The hemostasis and fibrinolysis variables, however, underwent no clinically significative changes.
Conclusion: Repeated bleedings change most hemorheological variables. By decreasing cytocrit and viscosity, reducing aggregability and increasing blood cell deformability an optimal milieu to help prevent thrombosis is artificially created.

The multicenter, phase III GMMG ReLApsE trial (EudraCT-No:2009-013856-61) randomized relapsed and/or refractory multiple myeloma (RRMM) patients equally to lenalidomide/dexamethasone (LEN/DEX, 25mg days 1-21/40mg weekly, 4-week cycles) re-induction, salvage high dose chemotherapy (sHDCT, melphalan 200mg/m2), autologous stem cell transplantation (ASCT) and LEN maintenance (10mg/day; transplant arm, n=139) versus continuous LEN/DEX (control arm, n=138). Ninety-four percent of patients had received frontline HDCT/ASCT. We report an updated analysis of survival endpoints with a median follow-up of 99 months.

Although recent evidence suggests that myeloid clonal hematopoiesis (M-CH) may influence lymphoma clinical outcome, its impact in mantle cell lymphoma (MCL) remains unclear. Here, we report a comprehensive NGS-based analysis of the M-CH mutational landscape at baseline and follow-up in patients enrolled in the Fondazione Italiana Linfomi (FIL) MCL0208 phase 3 trial (NCT02354313), evaluating lenalidomide maintenance versus observation after chemoimmunotherapy and autologous stem cell transplantation (ASCT) in untreated young MCL patients. Overall, 254/300 (85%) enrolled patients (median age 57 years [32-66]) had a baseline sample available for CH analysis.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Background: Chronic graft-vs-host disease (cGvHD) is a severe immune-mediated complication that affects patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Oral manifestations of cGvHD, such as ulcers and mucosal inflammation, significantly impair quality of life and often require long-term treatment. Existing therapies provide limited relief, prompting the exploration of new approaches, including the use of autologous platelet lysate (PL) gel for its regenerative properties.

Introduction Multiple myeloma (MM) is a complex plasma cell malignancy characterized by clonal proliferation and monoclonal immunoglobulin production. Despite the availability of several prognostic markers for MM, many are challenging to implement routine clinical practice due to cost, complexity, or lack of standardization. Red cell distribution width (RDW), a cost-effective and routinely measured parameter in complete blood counts, has gained increasing attention as a prognostic marker due to its association with disease severity and outcomes in MM.
