Seven patients with recurrent brain gliomas were treated by a single dose of CCNU 390 mg per m2. In five cases, chemotherapy was followed by autologous bone marrow transfusion containing 1.5 to 3 X 10(8) nucleated cells, 2.8 to 18 X 10(4) clusters plus colonies and 0.4 to 5 X 10(4) colonies forming cells per kg of body weight. Two patients were not grafted. None of these patients showed a clear cut response to the treatment as judged by clinical improvement and changes of the brain CT-scan. In 3 patients blood toxicity occurred early and was severe. In 4 others, it was milder and delayed. The duration and the severity of blood toxicity were modified by bone marrow transfusion but only slightly.

A wealth of research focused on African American populations has connected rs2814778-CC ("Duffy-null") to decreased neutrophil (neutropenia) and leukocyte counts (leukopenia). While it has been proposed that this variant is benign, prior studies have shown that the misinterpretation of Duffy-null associated neutropenia and leukopenia can lead to unnecessary bone marrow biopsies, inequities in cytotoxic and chemotherapeutic treatment courses, under-enrollment in clinical trials, and other disparities. To investigate the phenotypic correlates of Duffy-null status, we conducted a phenome-wide association study (PheWAS) across more than 1,400 clinical conditions in All of Us, the Vanderbilt University Medical Center's Biobank, and the Million Veteran Program.

Background: Autologous osteochondral transplantation (AOT) is an option to treat large osteochondral lesions of the talus (OLTs), accompanying subchondral cyst, and previous unsuccessful bone marrow stimulation (BMS) procedures. Although there is extensive literature on the outcomes of surgical interventions for medial osteochondral lesions, research focusing on lateral lesions remains limited. This article presents the intermediate-term clinical and radiologic outcomes following AOT for lateral OLTs.

Objectives: To investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL) in children.
Methods: A retrospective analysis was conducted on the clinical data, treatment, and prognosis of 8 children with AEL treated at the First Affiliated Hospital of Zhengzhou University from January 2013 to December 2023.
Results: Among the 7 patients with complete bone marrow morphological analysis, 4 exhibited trilineage dysplasia, with a 100% incidence of erythroid dysplasia (7/7), a 71% incidence of myeloid dysplasia (5/7), and a 57% incidence of megakaryocytic dysplasia (4/7).

Background: The prognosis of a plasma cell neoplasm (PCN) varies depending on the presence of genetic abnormalities. However, detecting sensitive genetic mutations poses challenges due to the heterogeneous nature of the cell population in bone marrow aspiration. The established gold standard for cell sorting is fluorescence-activated cell sorting (FACS), which is associated with lengthy processing times, substantial cell quantities, and expensive equipment.
