Cross-sectional. General community. Adults (N = 193) aged ≥ 50 years with chronic knee pain. Physical performance measures included Six-Minute Walk test, Timed Up and Go test, and 20-feet timed walk test. Quality of life (QOL) was measured by the Medical Outcomes Study Short Form-12 Health Survey. Brief Pain Inventory (BPI) and Brief Fatigue Inventory (BFI) were used to evaluate pain and fatigue. Multiple linear regression analyses were conducted to examine associations of coexisting pain and fatigue severity with physical performance and quality of life. Based on BPI and BFI scores, participants were categorized into four severity groups mild pain/fatigue; moderate pain/mild fatigue; mild pain/moderate fatigue; and moderate pain/fatigue (which included severe pain/fatigue). The moderate pain/fatigue group had significantly worse physical performance on Six o pain should be included as a standard examination for chronic knee pain.Per- and poly-fluoroalkyl substances (PFAS) are widely found in the environment because of their extensive use and persistence. Although several PFAS are well studied, most lack toxicity data to inform human health hazard and risk assessment. This study focused on 4 model PFAS perfluorooctanoic acid (PFOA; 8 carbon), perfluorobutane sulfonate (PFBS; 4 carbon), perfluorooctane sulfonate (PFOS; 8 carbon), and perfluorodecane sulfonate (PFDS; 10 carbon). Human primary liver cell spheroids (pooled from 10 donors) were exposed to 10 concentrations of each PFAS and analyzed at 4 time points. The approach aimed to (1) identify gene expression changes mediated by the PFAS, (2) identify similarities in biological responses, (3) compare PFAS potency through benchmark concentration analysis, and (4) derive bioactivity exposure ratios (ratio of the
