question:
Question: Are standard Radiographs Sufficient for Assessing Knee Mechanical Axis in Patients With Advanced Osteoarthritis?
Answer: Standard radiographs are not sufficient for determining MA, and HTA radiographs should be used while making surgical decisions aimed at correcting alignment to within ±3° or for assessing alignment post-total knee arthroplasty. In addition, surgical alignment outcomes reported in previous research using standard radiographs should be viewed with caution.
answer:
no


question:
Question: Does multidisciplinary care improve amputation-free survival in patients with chronic critical limb ischemia?
Answer: MDC pathways for the management of a population of CLI patients improved AFS by greater than twofold and should be the standard of care for the CLI population. Baseline nonambulatory status and unrevascularized patients also predict worse AFS. Wound healing remains prolonged regardless of preoperative or postoperative wound care. Future study is required to evaluate the costs and functional outcomes for MDC in the management of CLI.
answer:
yes


question:
Question: Is carcinoembryonic antigen mRNA in the mesenteric vein a predictor of hepatic metastasis in patients with resectable colorectal cancer : a long-term study?
Answer: This study failed to demonstrate the high predictive value of carcinoembryonic antigen messenger ribonucleic acid detection in the draining venous blood for the development of hepatic metastases. However, the authors demonstrated that the presence of cancer cells in the draining venous blood was the essential and initial step to the development of hepatic metastasis.
answer:

no
