Comparison of Direct Oral Anticoagulants for Treatment of Cerebral Venous Thrombosis - A Retrospective Cohort Study.

Limited available evidence comparing DOACs with warfarin suggests efficacy and safety of DOACs for CVT. We aimed to evaluate whether a specific DOAC is preferred for the treatment of CVT. This retrospective cohort study included adult patients with CVTs between September 2018 and September 2022 treated with a DOAC.

Impact of Hospital Volume on Survival for Pediatric Wilms Tumor.

Background: Treatment for children with Wilms tumor (WT) is multidisciplinary, often including surgery, chemotherapy, and sometimes radiation therapy. High-volume hospitals (HVH) have been associated with improved outcomes in cancer care. Our study evaluates the association of hospital volume and survival outcomes in pediatric WT management.

Access to Laparoscopic Pediatric Surgery: Do Ethnic and Racial Disparities Exist?

Introduction: Disparate access to laparoscopic surgery may contribute to poorer health outcomes among racial and ethnic minorities, especially among children. We investigated whether racial and ethnic disparities in laparoscopic procedures existed among four common surgical operations in the pediatric population in the United States.

Methods: Using the American College of Surgeons National Surgical Quality Improvement Program-Pediatrics, we conducted a retrospective review of pediatric patients, aged less than 18 y old, undergoing appendectomy, fundoplication, cholecystectomy, and colectomy from 2012 to 2021.

Human ASXL1-Mutant Hematopoiesis Is Driven by a Truncated Protein Associated with Aberrant Deubiquitination of H2AK119.

Unlabelled: Mutations in additional sex combs like 1 (ASXL1) confer poor prognosis both in myeloid malignancies and in premalignant clonal hematopoiesis (CH). However, the mechanisms by which these mutations contribute to disease initiation remain unresolved, and mutation-specific targeting has remained elusive. To address this, we developed a human disease model that recapitulates the disease trajectory from ASXL1-mutant CH to lethal myeloid malignancy.

Reprogramming Cancer into Antigen-Presenting Cells as a Novel Immunotherapy.

Unlabelled: Therapeutic cancer vaccination seeks to elicit activation of tumor-reactive T cells capable of recognizing tumor-associated antigens (TAA) and eradicating malignant cells. Here, we present a cancer vaccination approach utilizing myeloid-lineage reprogramming to directly convert cancer cells into tumor-reprogrammed antigen-presenting cells (TR-APC). Using syngeneic murine leukemia models, we demonstrate that TR-APCs acquire both myeloid phenotype and function, process and present endogenous TAAs, and potently stimulate TAA-specific CD4+ and CD8+ T cells.

The Cell Type-Specific 5hmC Landscape and Dynamics of Healthy Human Hematopoiesis and TET2-Mutant Preleukemia.

Unlabelled: The conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) is a key step in DNA demethylation that is mediated by ten-eleven translocation (TET) enzymes, which require ascorbate/vitamin C. Here, we report the 5hmC landscape of normal hematopoiesis and identify cell type-specific 5hmC profiles associated with active transcription and chromatin accessibility of key hematopoietic regulators. We utilized CRISPR/Cas9 to model TET2 loss-of-function mutations in primary human hematopoietic stem and progenitor cells (HSPC).

Antiplatelet Therapy in Older Patients Post-Myocardial Infarction.

This case study reviews appropriate antiplatelet treatment options for an older patient post-myocardial infarction and stent placement. This case investigates the benefits and risks associated with antiplatelet agents in older people and what patient- and drug-specific factors, such as adverse effects and drug interactions, to consider when choosing treatment.

Epstein-Barr virus-positive lymphoproliferative disorder manifesting as pulmonary disease in a patient with acute myeloid leukemia: a case report.

Background:  Patients with lymphoproliferative disorders following hematopoietic stem cell transplant (HSCT) most commonly present with fever and lymphadenopathy within the first 5 months of transplant. Pulmonary post-transplant lymphoproliferative disorder (PTLD) is a particularly aggressive and rapidly progressive disease, with high morbidity and mortality. There are a very limited number of reported pulmonary PTLD cases following HSCT in patients with acute myeloid leukemia (AML).
