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 tolerance to isoflurane occur in developing Xenopus laevis tadpoles?
Answer: We provide the first description of week-long exposures of vertebrates to surgical anesthetic concentrations of isoflurane, and the first report of such exposures in developing vertebrates. Tolerance to isoflurane does not occur in developing Xenopus laevis tadpoles. Taken together with studies in other organisms, the development of tolerance to ethanol but not isoflurane suggests that mechanisms shared by these drugs probably do not account for the development of tolerance.
answer:

no
