[Q]: Question: Does exacerbation of headache during dihydroergotamine for chronic migraine alter outcome?
Answer: After controlling for nausea and other factors, headache exacerbation with DHE infusions is not an independent predictor of poor headache outcome and clinicians should not interpret its presence as a reason to stop treatment. The focus of management should be on controlling nausea as it is the most important modifiable factor in achieving a good headache outcome with an inpatient course of IV DHE for chronic migraine.
[A]: no


[Q]: Question: Does co-Transplantation of Skin-Derived Precursors and Collagen Sponge facilitate Diabetic Wound Healing by Promoting Local Vascular Regeneration?
Answer: Accelerated wound healing and enhanced local capillary regeneration could be observed 14 days after skin ablation from both SKPs and collagen sponge co-transplanted and collagen sponge only groups. Subsequent analyses further revealed superior pro-angiogenic effects from the SKP and collagen sponge co-delivered group, which are mainly attributable to in vivo transdifferentation and paracrine signalling of the SKPs.
[A]: yes
