Systemic inflammation and lymphocyte activation precede rheumatoid arthritis.

Some autoimmune diseases, including rheumatoid arthritis (RA), are preceded by a critical subclinical phase of disease activity. Proactive clinical management is hampered by a lack of biological understanding of this subclinical 'at-risk' state and the changes underlying disease development. In a cross-sectional and longitudinal multi-omics study of peripheral immunity in the autoantibody-positive at-risk for RA period, we identified systemic inflammation, proinflammatory-skewed B cells, expanded Tfh17-like cells, epigenetic bias in naive T cells, TNF+IL1B+ monocytes resembling a synovial macrophage population, and CD4 T cell transcriptional features resembling those suppressed by abatacept (CTLA4-Ig) in RA patients.

Estimating the Prevalence of Using Suspected Counterfeit Medications in the General Population.

Introduction: Counterfeit medications, sometimes referred to as "fake" or falsified drugs or pills, are drugs that are illicitly manufactured but designed to look like legitimate pharmaceuticals. Counterfeit medications are a growing public health concern. This study estimated the prevalence of self-reported use of suspected counterfeit medications by adults in the US and to assess what ingredients these individuals suspected were in the counterfeit medications.

Expanding the Interpretive Potential of Eye Tracking for the Rorschach: Replication and Extension of the Findings of Ales et al. (2020).

The present study was undertaken to determine if the findings of Ales et al. (2020) could be replicated and extended, especially in light of the replication crisis in psychology and the social sciences. Ales et al.

Clonal IgA and IgG autoantibodies from individuals at risk for rheumatoid arthritis identify an arthritogenic strain of .

The mucosal origins hypothesis of rheumatoid arthritis (RA) proposes a central role for mucosal immune responses in the initiation or perpetuation of the systemic autoimmunity that occurs with disease. However, the connection between the mucosa and systemic autoimmunity in RA remains unclear. Using dual immunoglobulin A (IgA) and IgG family plasmablast-derived monoclonal autoantibodies obtained from peripheral blood of individuals at risk for RA, we identified cross-reactivity between RA-relevant autoantigens and bacterial taxa in the closely related families and .
