question:
Question: Does extended pattern prostate biopsy minimize the volume-grade bias in prostate cancer detection?
Answer: Although more high grade cancers are detected with extended pattern biopsy, there is no differential upgrading with respect to prostate volume. Based on these observations extended prostate sampling in trials of agents that decrease prostate volume would have minimal impact on volume-grade associations.
answer:
no


question:
Question: Do gNAS gene variants affect β-blocker-related survival after coronary artery bypass grafting?
Answer: GNAS haplotypes independently associate with an increased risk of death after primary coronary artery bypass graft surgery. These results are most pronounced in patients receiving βAR blockers, strengthening the rationale for personalized treatment, to decrease medication side effects and improve outcomes.
answer:
yes
