Response: Emergency department overcrowding is an urgent health priority and chest pain is a common reason for emergency department visits. We developed a new protocol that uses high sensitivity cardiac troponin testing with a risk assessment tool that guides decisions on discharge and stress testing for patients presenting with chest pain. The protocol allows us to rule out heart attacks more quickly than the protocols utilizing an older troponin assay.

MedicalResearch.com: What is the background for this study?
Response: Roughly 20% of men with prostate cancer have a family history of the disease, and 5% meet criteria for hereditary prostate cancer. Although prostate cancer has the greatest heritability of all common cancers (twice that of breast cancer), extensive heterogeneity of its inherited causes has presented a considerable obstacle for traditional pedigree-based genetic investigative approaches. Inherited causes across, as well as within families are diverse.
This study introduced a new familial case-control study design that uses extent of family history as a proxy for genetic burden. It compared a large number of men with prostate cancer, each from a separate family with a strong history of the disease, to screened men with no personal or family history. The study comprehensively deconstructs how the 8q24 chromosomal region impacts risk of hereditary prostate cancer, introducing several new analytical approaches. The locus had been known to alter risk of prostate, breast, colon, ovarian, and numerous additional cancers.
