question:
Question: Does frailty predict major bleeding within 30days in elderly patients with Acute Coronary Syndrome?
Answer: Frailty phenotype, as a marker of biological vulnerability, is an independent predictor of major bleeding in elderly patients with ACS. Frailty can play an important role in bleeding risk stratification and objective indices should be integrated into routine initial evaluation of these patients.
answer:
yes


question:
Question: Does incorporating Serum Level of Hepatitis B Surface Antigen or Omitting Level of Hepatitis B Virus DNA Affect Calculation of Risk for Hepatocellular Carcinoma in Patients Without Cirrhosis?
Answer: Including data on serum level of HBsAg or removing data on level of HBV DNA do not alter the accuracy of the REACH-B scoring system in determining HCC risk in patients with chronic HBV infection without cirrhosis. It might be cost effective to replace the test for HBV DNA with assays to measure HBsAg in determining HCC risk. These modified scoring systems might replace the REACH-B system in specific situations.
answer:

no
