Abstract
Objective Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect the central nervous system in multiple ways, including causing cognitive dysfunction. Cognitive dysfunction is a common complaint of SLE patients yet diagnosis is challenging, time consuming, and costly. This study evaluated the Self-Administered Gerocognitive Exam (SAGE) as a screening test for cognitive impairment in a cohort of SLE patients. Methods A total of 118 SLE patients completed the SAGE. Providers completed the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the Systemic Lupus International Collaborative Clinics Damage Index (SLICC-DI). SAGE scores were grouped into normal (>16) and abnormal (≤16) categories. Univariate and multivariate analyses were performed. Results Of the 118 participants, 21(18%) scored ≤16 on the SAGE instrument. In univariate analysis, race, ethnicity, household income, and SLICC-DI scores were associated with the SAGE ( p < 0.05). In multivariable analysis, abnormal SAGE score was independently associated with higher SLICC-DI score (odds ratio (OR) = 1.44, 95% confidence intervals 1.04-1.99, p = 0.03)), Hispanic ethnicity (OR = 43.4, 95% CI 3.1-601, p = 0.005), and lower household income (OR = 11.9 for ≤$15,000 vs >$50,000, 95% CI 2.45-57, p = 0.002). Conclusions In SLE patients, this study demonstrates an independent relationship between neurocognitive impairment (as measured by the SAGE) and higher lupus-related damage, as measured by the SLICC-DI, and lower household income. Abnormal SAGE scores were also associated with Hispanic ethnicity. A language barrier could explain this because the SAGE instrument was conducted in English only. The SAGE was feasible to measure in the clinic setting.

Abstract
Muskrat (Ondatra zibethicus) immunoglobulin fraction was separated from whole serum by Protein A Sepharose chromatography. In serum electrophoresis, this fraction had a gamma motility; when electrophoresed on a polyacrylamide gel with sodium dodecyl sulfate it resolved into two protein bands of approximately 52 and 25 kilodaltons, respectively. These bands were consistent with molecular weights of known heavy and light chains of immunoglobulin G (IgG) in other closely related species. Furthermore, the putative muskrat immunoglobulins had a strong cross-reactivity with mouse IgG1, IgG3, and kappa chain in an enzyme-linked immunosorbent assay. We propose, that the proteins bound to the Protein A Sepharose represent muskrat immunoglobulins of the IgG class.
