Diffuse midline glioma (DMG) H3K27-altered is one of the most malignant childhood cancers. Radiation therapy remains the only effective treatment yet provides a 5-year survival rate of only 1%. Several clinical trials have attempted to enhance radiation antitumor activity using radiosensitizing agents, although none have been successful.

Article Synopsis
  • - The study of Wilms tumour, which began with Alfred Knudson's 'two-hit' model, has advanced significantly over the last 50 years, leading to important discoveries in its genetics and biology.
  • - Research has focused on identifying prognostic biomarkers to improve treatment outcomes, although variability in these biomarkers within tumors creates challenges for individual patient care.
  • - Despite progress, ongoing investigations aim to deepen molecular understanding of Wilms tumour, including causes of relapse and bilateral cases, with international collaboration being key to addressing these complex issues.

Unlabelled: Long noncoding RNAs (lncRNA) play an important role in gene regulation and contribute to tumorigenesis. While pan-cancer studies of lncRNA expression have been performed for adult malignancies, the lncRNA landscape across pediatric cancers remains largely uncharted. Here, we curated RNA sequencing data for 1,044 pediatric leukemia and extracranial solid tumors and integrated paired tumor whole genome sequencing and epigenetic data in relevant cell line models to explore lncRNA expression, regulation, and association with cancer.

Introduction And Leadership Framework: While the scope of a pharmacist's work has grown, continued advocacy is needed to ensure that their skillset is used to the best advantage of the patient. To accomplish this aim, the University of Utah College of Pharmacy created an elective advocacy and leadership class to train students in leadership and advocacy methods, with a focus on enabling students to practice advocacy within the state of Utah throughout the class.

Educational Context And Methods: In addition to traditional lectures, this class asked students to apply the knowledge learned in class to projects within their sphere of influence.

Purpose: With expanding roles of clinic-embedded pharmacists comes the need to identify routes for optimization, soliciting and addressing feedback, and justifying the position(s) to the employing institution. Studies have demonstrated the benefit of integrating pharmacists into healthcare teams, but these opportunities remain largely limited to major health systems due to a lack of billing avenues for and familiarity with the services pharmacists can provide.

Methods: With funding from and partnership with a third-party payor, a pharmacist was incorporated into a private physician-owned clinic to be a resource to the providers and provide comprehensive medication management to patients.

Ripple Effects Mapping (REM) is a qualitative data analysis approach that combines mind mapping with inductive analysis to condense data obtained from group interviews. One benefit of REM is the ability to identify unintended outcomes, or "ripples," of the intervention of interest. Ripples are visually represented by a mind map created during the REM session.

Over the last decade, sequencing of primary tumors has clarified the genetic underpinnings of Wilms tumor but has not affected therapy, outcome, or toxicity. We now sharpen our focus on relapse samples from the umbrella AREN03B2 study. We show that over 40% of relapse samples contain mutations in SIX1 or genes of the MYCN network, drivers of progenitor proliferation.

Diffuse midline glioma (DMG) is a type of lethal brain tumor that develops mainly in children. The majority of DMG harbor the K27M mutation in histone H3. Oligodendrocyte progenitor cells (OPCs) in the brainstem are candidate cells-of-origin for DMG, yet there is no genetically engineered mouse model of DMG initiated in OPCs.

Background: Cancer survivors have a higher risk for developing cardiovascular diseases than the general population.

Objectives: The aim of this study was to investigate whether cardiovascular mortality overtakes cancer-specific mortality during cancer survivorship and, if so, at what point cardiovascular disease becomes the dominant cause of death.

Methods: This cohort study used linked English electronic health records, including death registration data.

Pediatric high-grade gliomas, specifically diffuse midline gliomas, account for only 20% of clinical cases but are 100% fatal. A majority of the DMG cases are characterized by the signature K27M mutation in histone H3. The H3K27M mutation opposes the function of enhancer of zeste homolog 2 (EZH2), the methyltransferase enzyme of the polycomb repressor complex 2.

Background: For five decades, blood pressure lowering treatment has been recommended for patients with hypertension (currently defined as blood pressure of ≥140/90 mm Hg). In the past 20 years, guidelines for treatment began incorporating predicted absolute cardiovascular disease risk (predicted risk) and reducing blood pressure thresholds. The blood pressure threshold at which to start treatment has become a secondary consideration in some countries.

Purpose: As the pharmacist's role expands, particularly in primary care practice settings, there is an opportunity for expansion of pharmacy technician duties to aid in administrative and clinical tasks that do not require the pharmacist's professional judgment. Identifying, defining, and expanding the roles of pharmacy technicians has been deemed a key part of the pharmacy practice model. These roles have been shown to enhance pharmacist efficiency and patient outreach; however, examples of the various innovative activities performed by technicians in the primary care setting are lacking in the literature.

Background: Platelet-derived growth factor (PDGF) signaling, through the ligand PDGF-A and its receptor PDGFRA, is important for the growth and maintenance of oligodendrocyte progenitor cells (OPCs) in the central nervous system (CNS). PDGFRA signaling is downregulated prior to OPC differentiation into mature myelinating oligodendrocytes. By contrast, PDGFRA is often genetically amplified or mutated in many types of gliomas, including diffuse midline glioma (DMG) where OPCs are considered the most likely cell-of-origin.

Longitudinal data is commonly analysed to inform prevention policies for diseases that may develop throughout life. Commonly methods interpret the longitudinal data as a series of discrete measurements or as continuous patterns. Some of the latter methods condition on the outcome, aiming to capture 'average' patterns within outcome groups, while others capture individual-level pattern features before relating these to the outcome.

Background: The past few decades have seen substantial improvements in cancer survival, but concerns exist about long-term cardiovascular disease risk in survivors. Evidence is scarce on the risks of specific cardiovascular diseases in survivors of a wide range of cancers to inform prevention and management. In this study, we used large-scale electronic health records data from multiple linked UK databases to address these evidence gaps.
