When formed in vivo, murine hemostatic thrombi exhibit a heterogeneous architecture comprised of distinct regions of densely and sparsely packed platelets. In this study, we utilize high-resolution electron microscopy alongside machine learning and physics-based simulations to investigate how such clot microstructure impacts molecular diffusivity. We used Serial Block Face - Scanning Electron Microscopy (SBF-SEM) to image select volumes of hemostatic masses formed in a mouse jugular vein, producing high-resolution 2D images. Images were segmented using machine learning software (Cellpose), whose training was augmented by manually segmented images. The segmented images were then utilized as 2D computational domains for Lattice Kinetic …

Internal Medicine, East Africa
Background: Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke that is more common in young, especially female, adults and can be challenging to diagnose due to its frequently non-specific presentation and diverse risk factors. Most cases are idiopathic, and international guidelines do not recommend routine investigations for underlying thrombophilia. Timely diagnosis, with prompt neuroimaging and guideline-based treatment, leads to good outcomes. However, in the literature on CVST from sub-Saharan Africa, the gap is substantial, with the few cases described as being related to systemic and/or brain infections. We describe here the largest cohort of CVST from the …

Comparison Between Acute Leukemia Screening Tube And Lineage-Specific Panels For The Diagnosis Of Acute Leukemia In Kenya, Nancy Okinda, Geoffrey Omuse, Elizabeth Kagotho, Douglas Munga
Pathology, East Africa
Purpose: Acute leukemia is a group of hematologic malignancies categorized according to the immature cells that proliferate and replace the normal bone marrow. Flow cytometry has emerged as a cornerstone in the diagnosis of hematologic malignancies. Staged analysis with a screening tube containing specific lineage markers determines the need for subsequent testing if there is an abnormal population (blasts). The specific lineage panels to be analyzed are determined depending on the positive markers in the screening tube. This study aimed to determine the agreement of diagnosis using the acute leukemia screening tube (ALST) and the lineage-specific panel.
Methods: This was …

Complications And Management Of Idiopathic Multicentric Castleman Disease, Kavanya Feustel, Jacob W. Keeling, Olivia Makos, Dmitriy Scherbak
HCA Healthcare Journal of Medicine
Background
The pathophysiology of idiopathic multicentric Castleman disease (iMCD) is poorly understood compared to the other subtypes of MCD, which has contributed to limited treatment options and poor prognosis for iMCD patients. The pathogenesis of iMCD is thought to be mediated in part by dysregulation of interleukin (IL)-6.
Case Presentation
We present a case report of a 39-year-old Caucasian man with siltuximab-refractory iMCD. He presented with severe lower extremity lymphedema and wounds. His disease progressed through standard-of-care siltuximab. Due to his severe disease-related morbidity, he contracted recurrent infections, often complicated by sepsis. Ultimately, he required a left lower extremity amputation. …

Immune Thrombocytopenic Purpura Association With Epstein-Barr Virus, Amer Aldamouk, Bachr Masri, Ali Khan, Pulkita Uppal
Graduate Medical Education Research Journal
Immune thrombocytopenia (ITP), also referred to as idiopathic thrombocytopenic purpura, is an acquired form of thrombocytopenia caused by antibodies directed against platelet glycoproteins, particularly anti-GpIIb/IIIa antibodies. Epstein-Barr virus (EBV), a herpes virus infecting a large majority of the population before adulthood, has been implicated in various immune-mediated disorders, including ITP. In this report, we present a case of a young adult female with a history of thrombocytopenia who was found to have severe thrombocytopenia attributed to chronic EBV infection. Despite initial treatment with corticosteroids and intravenous immunoglobulin (IVIG), the patient's condition necessitated second-line therapies, including rituximab and thrombopoietin receptor agonists. …

Cars And Trucks: Driving A Paradigm Shift In Hematologic Malignancies, Christine Charek, Tia Solh
Lynchburg Journal of Medical Science
Hematologic malignancies account for a significant number of annual cancer diagnoses and deaths across the globe. Historically, the prognosis for relapsed and/or refractory disease after standard therapies, such as chemotherapy and/or radiation, was poor. Chimeric antigen receptor (CAR) T-cell therapy offers an additional treatment option. While promising, this type of immunotherapy also comes with potentially severe side effects, toxicities, and limitations. A better understanding of the development, administration, and management of patients undergoing treatment can provide the general clinician with the knowledge to assist within a multidisciplinary team to ultimately improve patient outcomes.

Cooper Rowan Medical Journal
Pyruvate kinase deficiency (PKD) is an autosomal recessive disorder and the most common cause of chronic hemolytic anemia secondary to red blood cell (RBC) enzyme defects. Treatment is mainly supportive including splenectomy and transfusions. Mitapivat, an oral allosteric activator of defective pyruvate kinase, was approved by the FDA in February 2022 for treatment of adults with PKD. However, because Mitapivat undergoes liver metabolism, patients must have stable liver profiles prior to initiation of therapy. We present a case of PKD complicated by hemophagocytic lymphohistiocytosis (HLH). We initiated steroid therapy for his HLH with the intent to subsequently start Mitapivat. We …

The heterogeneity of the hematopoietic system was largely veiled by traditional bulk sequencing methods, which measure the averaged signals from mixed cellular populations. In contrast, single-cell sequencing has enabled the direct measurement of individual signals from each cell, significantly enhancing our ability to unveil such heterogeneity. Building on these advances, numerous single-cell multi-omics techniques have been developed into high-throughput, routinely accessible platforms, delineating the precise relationships among different layers of the central dogma in molecular biology. These technologies have uncovered the intricate landscape of genetic clonality and transcriptional heterogeneity in both normal and malignant hematopoietic systems, highlighting their roles in …

In myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) with TP53 aberrations, dissecting the interaction amongst patient, disease and treatment factors are important for therapeutic decisions and prognostication. This retrospective analysis included patients with newly diagnosed MDS (>5% blasts) and AML with TP53 mutation(s) treated at MD Anderson Cancer Center. We factored patient age, TP53 aberration burden, therapy intensity and use of venetoclax in the AML subgroup, and allogeneic hematopoietic stem cell transplantation (HSCT) to interrogate outcomes. TP53 was annotated as high-risk (TP53HR) if >1 mutation, one mutation plus allelic deletion or a single mutation with variant allele frequency …

Acute myeloid leukemia (AML) resides in an immune-rich microenvironment, yet, immune-based therapies have faltered in eliciting durable responses. Bridging this paradox requires a comprehensive understanding of leukemic interactions within the bone marrow microenvironment. We optimized a high-throughput tissue-microarray-based pipeline for high-plex spatial immunofluorescence and mass cytometry imaging on a single slide, capturing immune, tumor, and structural components. Using unbiased clustering on the spatial K function, we unveiled the presence of tertiary lymphoid-like aggregates in bone marrow, which we validated using spatial transcriptomics and an independent proteomics approach. We then found validated TLS signatures predictive of outcomes in AML using an …

Research Days
Background: Diamond Blackfan anemia (DBA) is an inherited bone marrow failure syndrome caused by ribosomal protein gene mutations leading to apoptosis of erythroid progenitors. We identified a novel heterozygous variant (c.167+769C>T) in the noncoding region of RPL30 in a patient diagnosed with DBA.
Objectives/Goal: We hypothesized that this variant stunts erythroid differentiation at the proerythroblast stage and is pathogenic for DBA.
Methods/Design: We developed an induced pluripotent stem cell (iPSC) model with a wild type (WT) and three CRISPR-Cas9 edited RPL30 mutant clones. iPSCs were differentiated into hematopoietic stem cells, which were assessed by flow cytometry and single cell …

Inpatient Thrombophilia Workup After Acute Vte: The Tests That Don’T Pay It Forward, Eliakim Munda, Bs, Ruben Rhoades, Md, Ms
Health Equity and Quality Improvement (HEQI) Summit
Background
- Venous thromboembolism is a complex multifactorial disease that is influenced by genetic, environmental and behavioral risk factors.
- Testing for inherited thrombophilia is commonly performed after a VTE event to help identify underlying genetic risk factors and assess the risk of recurrence.
- Despite clinical guidelines advising against thrombophilia testing in patients with acute VTE, these tests continue to be ordered even though lab results are unlikely to alter treatment decisions
Problem Statement
- At TJUH, activity and genetic assays are frequently ordered for patients with acute VTE during admission, increasing the likelihood of false- positive results that may lead to unnecessary …

Health Equity and Quality Improvement (HEQI) Summit
Background
- Intravenous (IV) formulations of iron are safe, quick, easy to administer, and are indicated in patients with Iron Deficiency.
- Prior formulations of IV iron were associated with anaphylaxis and have since been removed from the market -- healthcare workers remain anxious about their potential for reactions
- Rate of anaphylactic reactions are about 1 in 200,000 infusions
- Current IV formulations available can be associated with a complement mediated, pseudo-allergy, that presents with flushing, myalgia/arthralgia, and chest pressure. Reactions are dependent on infusion rate and improve after stopping the infusion.
- Premedication with acetaminophen and diphenhydramine are often ordered for IV iron …

Health Equity and Quality Improvement (HEQI) Summit
Background
- Thomas Jefferson University Hospital Center City (TJUH CC) campus is the predominant referral center for patients with hematologic malignancy in parts of PA, DE, and NJ
- Patients accepted for transfer to TJUH under Medical Oncology, often have longer than anticipated time to transfer (time from transfer acceptance to patient physical arrival)
- Long transfer times delay potentially lifesaving diagnostics and treatment; this can be most concerning for patients with aggressive hematologic malignancies given need for subspecialist management
- Data review from 2023-2024 showed patients with aggressive hematologic malignancy (defined as acute leukemia, chronic myeloid leukemia in blast crisis, diffuse large B …

Altered protein homeostasis through proteasomal degradation of ubiquitinated proteins is a hallmark of many cancers. Ubiquitination, coordinated by E1, E2, and E3 enzymes, involves up to 40 E2-conjugating enzymes in humans to specify substrates and ubiquitin linkages. In a screen for E2 dependencies in acute myeloid leukemia (AML), ubiquitin conjugating enzyme E2 N (UBE2N) emerged as the top candidate. To investigate UBE2N's role in AML, we characterized an enzymatically defective mouse model of UBE2N, revealing UBE2N's requirement in AML without an impact on normal hematopoiesis. Unlike other E2s, which mediate lysine-48 (K48) polyubiquitination and degradation of proteins, UBE2N primarily synthesizes …

INTRODUCTION: Acute myeloid leukemia (AML) is a disease of the elderly with a median age at diagnosis of 68 and with a very poor prognosis outside of those patients who have cytogenetic and/or molecular findings which confer a better prognosis. Most fit patients are treated with chemotherapy and then allogeneic hematopoietic stem cell transplant if they are intermediate or poor risk by ELN 2022 criteria (aSCT). aSCT is the mainstay of curative treatment although many patients are not candidates due to age, performance status, and comorbidities. In patients who are not candidates for curative treatment, low-intensity chemotherapy regimens, including monotherapy …

Sickle cell disease (SCD) affects millions of individuals worldwide, and is characterized by both acute, episodic pain and chronic, persistent pain. Despite the significant burden of the disease, clinicians continue to face significant challenges in treating SCD pain due to variability in pain experiences. The objectives of this study were (1) to identify distinct pain subgroups based on demographic and biopsychosocial characteristics and (2) to evaluate the relationship between the subgroups and pain impact - a SCD-disease specific measure of pain interference. To achieve these objectives, we performed a hierarchical cluster analysis on a cross-sectional sample of adults with SCD …

Background
Social determinants of health (SDOH) create barriers to seeking care regularly, especially for patients with chronic disease. Patients with moderate-severe hemophilia A and B (factor 8 and 9 deficiencies respectively) have a life-long higher risk of bleeding and require chronic therapies. Specialized care is offered through hemophilia treatment centers (HTCs); however, these can be difficult to access for some individuals. Previous SDOH research in this patient population has been limited; therefore, it can be difficult to identify the barriers to care that exist. There is a need to examine SDOH more thoroughly to create patient-directed interventions to improve access …

SY-2101 is a novel oral formulation of arsenic trioxide (ATO). Although IV ATO in combination with all trans retinoic acid is highly efficacious in treating acute promyelocytic leukemia (APL), there remains a significant unmet need due to the treatment burden associated with receiving daily ATO infusions for nearly a year and the risk of complications associated with indwelling central catheters. The pharmacokinetics (PK), safety, and tolerability of SY-2101 and ATO IV after single- and multiple-dose administration and the impact of food on PK for SY-2101 were evaluated in this phase 1 study in 15 participants with APL. SY-2101 in the …
