Q: Question: Is the serum level of NX-DCP-R , but not DCP , increased in alcoholic liver disease without hepatocellular carcinoma?
Answer: NX-DCP-R, but not DCP, was not increased in alcoholics without HCC. As for negative screening for HCC, the specificity of the NX-DCP-R in alcoholics without HCC was better than that of DCP in alcoholics without HCC, and so could be a useful negative screening tool for HCC in millions of alcoholics worldwide.

Q: Question: Is central venous saturation an alternative to mixed venous saturation during cardiopulmonary bypass in coronary artery surgery patients?
Answer: Although mean biases between the measurements were low, limits of agreement were too large to provide a clinically acceptable estimation of SvO(2) by ScvO(2) in these conditions. Variations in regional oxygen consumption seem to be the main factor worsening the relationship.

A: no

Q: Question: Does the benefit of geriatric intervention in surgery-increased throughput necessarily need more beds?
Answer: There was an important benefit to the availability of coloproctology and general surgical beds in this acute Trust. More efficient rehabilitation of elderly patients reduces 'bed blockage' post-operatively, and allows more effective use of available resources. Co-ordination of the geriatric service with the specialized stoma support service allows earlier discharge of the elderly, and their relocation to appropriate premises where long-term changes in bowel habit and problems with stoma care can be managed away from the acute surgical unit.

A:
no
