Front Immunol 2021 5;12:653611. Epub 2021 Jul 5.

Post Graduation Program in Biosciences and Physiopathology, Department of Clinical Analysis and Biomedicine, State University of Maringá, Paraná, Brazil.

Ankylosing spondylitis (AS) is a chronic autoimmune inflammatory disease that mainly affects the axial and sacroiliac joints. Single-nucleotide polymorphisms (SNPs) in genes encoding cytokines have been associated with AS, which can interfere with the production of these cytokines and contribute to the development of AS. In order to contribute to a better understanding of the pathology of AS, our objective was to investigate a possible association of the -1082 A>G SNP (rs1800896) with AS and to evaluate the serum levels of TNF-α, IL-10, IL-17A, and IL-17F in AS patients and controls comparing them with their respective genotypes ( rs1800629, rs1800896, rs2275913, and rs763780).

Outlier-response pattern checks to improve measurement with the Positive and Negative Syndrome Scale (PANSS).

Psychiatry Res 2021 Jul 15;303:114114. Epub 2021 Jul 15.

Bar Ilan University, Ramat Gan, Israel.

We derived outlier-response pattern checks to flag possible careless PANSS (Positive and Negative Syndrome Scale) administrations based on analysis of 122,000 administrations from 29 registration trials of antipsychotics from NEWMEDS data repository. Flags identify outlier administrations based on frequency of endorsing a given response value, use of even or odd values, consecutive use of same value, variability of values, responses per specific item, and values on multiple items. Outlier flags were compared to published expert derived scoring inconsistency flags and tested in Monte Carlo simulated data, with known inconsistency, and appear to be useful at identifying administrations that require review.
