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.

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.

Article Synopsis
  • The study focused on improving chronic hepatitis B (CHB) testing in primary and community care settings to aid in elimination efforts, aiming to assess various implementation strategies from existing literature.
  • A systematic review and meta-analysis were conducted, analyzing 25 studies with over 130,000 participants, but found that no studies were conducted in low-and-middle-income countries.
  • Key findings showed that community strategies, like education from lay health workers, and primary care strategies, such as electronic alerts and healthcare provider education, were effective, with a significant relationship observed between the number of strategy components and effectiveness.

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.

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.

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.

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).

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.

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).
