Article Synopsis
  • The study analyzed trends in uterine cancer diagnoses before and during the COVID-19 pandemic using data from 2001 to 2020.
  • In 2020, there were 4,232 fewer cases diagnosed than expected, resulting in a 9.3% decrease compared to projections based on previous trends.
  • The largest decreases in diagnoses were seen in Hispanic (14.6%) and Asian and Pacific Islander (12.0%) populations, emphasizing the need to focus health resources on these vulnerable groups post-pandemic.

Article Synopsis
  • In February 2024, the Society of Gynecologic Oncology held a journal club discussing new treatment options for advanced and metastatic endometrial cancer, highlighting recent advancements in the field.
  • Key topics included the importance of molecular characterization from The Cancer Genome Atlas (TCGA) and an overview of the updated 2023 FIGO staging for endometrial cancer.
  • The discussion also covered the promising results of four recent clinical trials on immunotherapy for advanced cases, particularly noting outcomes for mismatch repair deficient (dMMR) endometrial cancer, aiming for improved personalized treatment methods.

Introduction: Centering affected individuals and forming equitable institutional-community partnerships are necessary to meaningfully transform care delivery systems. We describe our use of the PRECEDE-PROCEED framework to design, plan, and implement a novel care delivery system to address perinatal inequities in San Francisco.

Methods: Community engagement (PRECEDE phases 1-2) informed the "Pregnancy Village" prototype, which would unite key organizations to deliver valuable services alongside one another, as a recurring "one-stop-shop" community-based event, delivered in an uplifting, celebratory, and healing environment.

There have been many recent changes in the treatment of endometrial cancer, most recently with the US Food and Drug Administration's (FDA) approval of dostarlimab in conjunction with standard-of-care chemotherapy in the frontline setting for mismatch repair-deficient (dMMR) populations. This review sought to summarize the publications and studies that have led to this practice-changing approval. Dostarlimab is an immune checkpoint inhibitor with a favourable safety profile and proven efficacy in the treatment of endometrial cancer, particularly dMMR endometrial cancer.

Purpose Of Review: To summarize the most recent publications explaining disparities among patients diagnosed with endometrial cancer and identify areas of improvement.

Recent Findings: Racial disparities in endometrial cancer care have been identified along the cancer continuum including risk, diagnosis, access to treatment, and overall survival. The mortality gap in endometrial cancer is one of the top five widest Black-White mortality gaps among all cancer diagnoses in the United States.

Introduction: Health inequities begin before birth with Black women being more likely to have low birth weight babies than White and Latina women. Although both Latina and Black women experience discrimination, only Black women appear to be affected.

Methods: In this study using medical records and face-to-face interviews, we systematically examined the role of discrimination (daily, environmental, vicarious) on continuous birth weight (controlling for gestational age and baby's gender) in a sample of 329 Black, Latina, and White pregnant women, as well as whether familism, prayer, and/or discrimination attribution buffered this association.

Purpose: Chimeric antibody Miltuximab®, a human IgG1 engineered from the parent antibody MIL-38, is in clinical development for solid tumour therapy. Miltuximab® targets glypican-1 (GPC-1), a cell surface protein involved in tumour growth, which is overexpressed in solid tumours, including prostate cancer (PCa). This study investigated the potential of Zr-labelled Miltuximab® as an imaging agent, and Lu-labelled Miltuximab® as a targeted beta therapy, in a mouse xenograft model of human prostate cancer.

Metagenomic sequencing of pooled nasal swabs from pigs with unexplained respiratory disease identified a large number of reads mapping to a previously uncharacterized porcine polyomavirus. polyomavirus 2 was most closely related to betapolyomaviruses frequently detected in mammalian respiratory samples.

Histones are essential elements of chromatin structure and gene regulation in eukaryotes. An unexpected attribute of these nuclear proteins is their antimicrobial activity. A framework for histone release and function in host defense in vivo was revealed with the discovery of neutrophil extracellular traps, a specialized cell death process in which DNA-based structures containing histones are extruded to ensnare and kill bacteria.

The sequences of M proteins, the major surface-associated virulence factors of the widespread bacterial pathogen group A Streptococcus, are antigenically variable but have in common a strong propensity to form coiled coils. Paradoxically, these sequences are also replete with coiled-coil destabilizing residues. These features are evident in the irregular coiled-coil structure and thermal instability of M proteins.
