Dr. Joshua Baker, first author of a paper recently published in "Arthritis & Rheumatology", "Associations Between Low Serum Urate, Body Composition, and Mortality", is our guest today. Dr. Baker, recognizing the controversy in whether low serum urate or uric acid (UA) level contribute to adverse outcomes, set out to evaluate the relation between low serum UA levels and sarcopenia, to assess whether sarcopenia confounds associations between these low levels and mortality.
