A Prospective Analysis of Opioid Prescription, Consumption, and Psychometric Correlations in Outpatient Plastic Surgery Procedures.

Understanding opioid prescription, consumption, and the factors related to these is important to prescribe opioids responsibly. Our primary purpose is to determine the factors predicting opioid prescription, and the secondary purpose is to examine the factors predicting opioid tablet consumption. A prospective cohort was evaluated using 2 surveys.

Time dependency for human papillomavirus circulating tumor DNA detection after chemoradiation as a prognostic biomarker for localized anal cancer.

Background: While detection of circulating tumor DNA (ctDNA) weeks after surgery is linked to recurrence for other solid tumors, the optimal time point for ctDNA assessment as a prognostic biomarker following chemoradiation for anal cancer is undefined.

Methods: Patients with stages I-III anal cancer treated with chemoradiation between 12/2020-5/2024 were evaluated for HPV ctDNA status at baseline, at the end of chemoradiation, and during surveillance using a droplet digital HPV ctDNA PCR assay targeting HPV E6 and E7 oncogenes for 13 oncogenic HPV types. Median recurrence-free survival (RFS) according to HPV ctDNA status was estimated via Kaplan-Meier and compared using a log-rank test.

The BLM-TOP3A-RMI1-RMI2 proximity map reveals that RAD54L2 suppresses sister chromatid exchanges.

Homologous recombination is a largely error-free DNA repair mechanism conserved across all domains of life and is essential for the maintenance of genome integrity. Not only are the mutations in homologous recombination repair genes probable cancer drivers, some also cause genetic disorders. In particular, mutations in the Bloom (BLM) helicase cause Bloom Syndrome, a rare autosomal recessive disorder characterized by increased sister chromatid exchanges and predisposition to a variety of cancers.

Combined PARP14 inhibition and PD-1 blockade promotes cytotoxic T cell quiescence and modulates macrophage polarization in relapsed melanoma.

Background: Programmed cell death 1 (PD-1) signaling blockade by immune checkpoint inhibitors (ICI) effectively restores immune surveillance to treat melanoma. However, chronic interferon-gamma (IFNγ)-induced immune homeostatic responses in melanoma cells contribute to immune evasion and acquired resistance to ICI. Poly ADP ribosyl polymerase 14 (PARP14), an IFNγ-responsive gene product, partially mediates IFNγ-driven resistance.
