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: Are mutational status of KIT and PDGFRA and expression of PDGFRA associated with prognosis after curative resection of primary gastrointestinal stromal tumors ( GISTs )?
Answer: Our data do not support the notion that expression of PDGFRA or mutations in KIT or PDGFRA are independent prognostic factors after curative resection of primary GIST.
answer:
no


question:
Question: Do referral letters for 2-week wait suspected colorectal cancer allow a 'straight-to-test ' pathway?
Answer: A significant number of patients would have had tests changed after a clinical consultation. However, only a small number required further investigations having had a consultation prior to their initial investigations. We conclude that 2-week wait suspected colorectal cancer patients should be seen in the clinic first and should not proceed 'straight-to-test'.
answer:

no
