In Tunisia, blood donation is voluntary, anonymous and non-remunerated. The aim of the study is to analyze donor motivation and sociology in the regional center of transfusion of Sfax. Between 14 May 2007 and 23 June 2007, a total of 903 Tunisian blood donors filled a questionnaire. Among the donors, 81.8% were men and have a mean age of 34.2 years and the majority of them have an age between 18 and 29 years. The middle social class was majority (77.8%) as well as the liberal profession (65.1%). Primary and secondary education were dominant (79.3%). Among the blood donors, 41.6% were new donors and 28.6% had a history of a single donation, 50.3% were voluntary and 49.7% replacement donors. The reasons motivating the voluntary donation were solidarity (69.9%), religion (21.2%), health benefit (3.6%) and insurance for the family (5.2%). The replacement donors refuse the voluntary donation for not obvious reasons (51%), lack of availability (13.3%), difficulties of accessibility of the sites of collection (7.6%), phobia of the blood and the stings (4.02%) or by refusal of blood donation (1.79%). The information and the raising awareness of the replacement donors could change in a near future their attitudes to become voluntary and regular donors. The implication of donor associations in the organization of the collections and the promotion of the blood donation would be of considerable contribution.

Dysregulated Clot Mechanics and Kinetics Impacted by Injury Severity, Predict Mortality After Trauma.

Introduction: Coagulopathy following traumatic injury impairs stable blood clot formation and exacerbates mortality from hemorrhage. Understanding how these alterations impact blood clot stability is critical to improving resuscitation. Furthermore, the incorporation of machine learning algorithms to assess clinical markers, coagulation assays and biochemical assays allows us to define the contributions of these factors to mortality.

Background Aims: Bulevirtide (BLV) is a novel and the only approved treatment option for patients with chronic hepatitis D (CHD). BLV alleviates liver inflammation already early during treatment when only minor HDV RNA changes are observed. We hypothesized that BLV-treatment may influence immune cells in CHD patients and performed a high-resolution analysis of natural killer (NK) cells before and during BLV-therapy.

Purpose: This study compared the outcomes of haploidentical-related donor (HRD) and umbilical cord blood (UCB) hematopoietic stem cell transplantation (HSCT) in pediatric patients with hematologic malignancies.
Methods: Data on patients who underwent HRD HSCT with post-transplant cyclophosphamide (n = 41) and UCB HSCT (n = 24) after targeted busulfan-based myeloablative conditioning with intensive pharmacokinetic monitoring between 2009 and 2018 were retrospectively analyzed.
Results: The median follow-up durations in the HRD and UCB groups were 7.

Introduction: Hematopoietic stem cell transplantation (HSCT) and chemotherapy are considered potentially curative options for post-remission therapy in acute myeloid leukemia (AML). However, the comparative effectiveness of these approaches in favorable- and intermediate-risk AML remains unclear and requires further investigation.
Methods: In this retrospective study, 111 patients diagnosed with de novo favorable- and intermediate-risk AML, categorized according to the ELN 2022 guidelines, were investigated to compare outcomes following autologous HSCT (auto-HSCT), matched sibling donor HSCT (MSD-HSCT), and chemotherapy.

Objective: To explore the differential gene expression in peripheral blood immune cells of individuals with type 2 diabetes mellitus (DM), comparing those with and without non-proliferative diabetic retinopathy (NPDR).
Methods: From a pool of 126 potential participants, 60 were selected for detailed analysis. This group included 12 healthy donors (HDs), 22 individuals with DM, and 26 with NPDR.
