Evaluating a Pragmatic Strength Alternative for Frailty Measurement and Assessing Its Predictive Capacity Against Established Frailty Instruments in Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Objective Frailty occurs prematurely in rheumatoid arthritis (RA) and is associated with poor health outcomes. We compared the performance of four frailty instruments, including a pragmatic alternative measure using chair sit‐to‐stand (STS), and evaluated their abilities to predict poor health outcomes.

Multidimensional worldline instantons [PDF]

Physical Review D, 2006
We extend the worldline instanton technique to compute the vacuum pair production rate for spatially inhomogeneous electric background fields, with the spatial inhomogeneity being genuinely two or three dimensional, both for the magnitude and direction of the electric field.

Associations of Rheumatoid Arthritis Disease Activity with Frailty Over Five Years of Follow‐up

Arthritis Care &Research, Accepted Article.
Objective To evaluate whether rheumatoid arthritis (RA) disease activity is associated with frailty both in cross‐section and longitudinally. Methods Participants within the Veterans Affairs Rheumatoid Arthritis registry enrolled from 2003 to 2022 were included. The exposure was RA disease activity measured by Disease Activity Score in 28‐joints (DAS28)
