Distance to Treatment With Radical Cystectomy in a Rural State: Long Car Rides, Equivalent Outcomes.

Introduction: Radical cystectomy is a complex surgery with better outcomes reported when performed at high-volume centers. This may lead to patients traveling farther for care. We examined the impact of travel distance on clinical outcomes.

PRState: Incorporating genetic ancestry in prostate cancer risk scores for men of African ancestry.

Background: Prostate cancer (PrCa) is one of the most genetically driven solid cancers with heritability estimates as high as 57%. Men of African ancestry are at an increased risk of PrCa; however, current polygenic risk score (PRS) models are based on European ancestry groups and may not be broadly applicable. The objective of this study was to construct an African ancestry-specific PrCa PRS (PRState) and evaluate its performance.

Prostate Specific Antigen Testing Behaviors for Prostate Cancer Screening Among U.S. Immigrants: A Cross-sectional Analysis Using the National Health Interview Survey.

Purpose: Immigrants constitute 14% of the U.S. population, and this group is especially vulnerable to poor health care access.

Endogenous Peptide Inhibitors of HIV Entry.

The discovery of the G-protein coupled-receptor (GPCR) CXCR4 as a major coreceptor of HIV-1 entry about three decades ago explained why the chemokine SDF-1/CXCL12 inhibits specific viral strains. The knowledge that RANTES, MlP-1α, and MlP-1β specifically inhibit other primary HIV-1 strains allowed the rapid discovery of CCR5 as second major viral coreceptor and explained why individuals with deletions in CCR5 are protected against sexual HIV-1 transmission. Here, we provide an update on endogenous ligands of GPCRs that act as endogenous inhibitors of HIV-1, HIV-2, and simian immunodeficiency virus (SIV) entry.

Luciferase reporter assays to monitor interferon signaling modulation by SARS-CoV-2 proteins.

We present a protocol for analyzing the impact of SARS-CoV-2 proteins in interferon signaling using luciferase reporter assays. Here, the induction of defined promoters can be quantitatively assessed with high sensitivity and broad linear range. The results are similar to those obtained using qPCR to measure endogenous mRNA induction.
