question:
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.
answer:
no


question:
Question: Is sleep disturbance after fracture related to emotional well-being rather than functional result?
Answer: At 12-month follow-up, poor sleep was independently associated with poor emotional status but not associated with poor functional status. The mental health status of patients with sleep difficulty in the latter stages of fracture healing should be carefully assessed to provide the highest level of care. The results of this study should allow orthopaedic trauma surgeons to counsel patients regarding expectations of difficulty sleeping after acute fractures.
answer:
yes


question:
Question: Does altered endosome biogenesis in prostate cancer have biomarker potential?
Answer: This discovery of altered endosome biogenesis in prostate cancer may lead to novel biomarkers for more precise cancer detection and patient prognosis.
answer:

yes
