Could the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) be a valid measure of disease activity in patients with psoriatic arthritis?
BASDAI performs similarly for axial and peripheral PsA but does not correlate well with external indicators of disease activity, such as treatment decisions.
Blood sampling from umbilical artery catheters induces a significant decrease in cerebral blood volume and cerebral oxygenation.
