TASK DEFINITION: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
PROBLEM: Question: Does serum HCV RNA titer predict the severity of liver damage in HCV carriers with normal aminotransferase levels?
Answer: In HCV carriers with normal aminotransferase levels viraemia does not predict the grade of HCV-related chronic liver disease (CLD), although subjects with higher HCV RNA levels seem to have more severe fibrosis. Although these data suggest that patients with higher viraemia might have more intense architectural changes and more severe progression of liver disease than those with lower levels of HCV replication, the weak and imprecise correlation leads us to conclude that HCV RNA quantitation is not a useful indicator in clinical practice in the selection of patients for liver biopsy.

SOLUTION: no

PROBLEM: Question: Is laser in situ keratomileusis surgery safe for military personnel?
Answer: There is a high risk of potential traumatic flap problems after LASIK and it is not recommended in army service.

SOLUTION: no

PROBLEM: Question: Is surfactant maturation delayed in human fetuses with diaphragmatic hernia?
Answer: Our results indicate that CDH does not impair surfactant storage in human fetuses. CDH lungs exhibited no trend toward a decrease in contents, or a delay in developmental changes for any of the studied surfactant components and surfactant maturation factors. Surfactant amounts are likely to be appropriate to lung size. These findings therefore do not support the use of surfactant therapy for infants with CDH. Moreover, they raise the question of the relevance of CDH animal models to explore lung biochemical maturity.

SOLUTION:
no
