INTRODUCTION: This study used the novel C-reactive protein-albumin-lymphocyte (CALLY) index to explore its relationship with the risk of developing gallstones. METHODS: This study conducted a cross-sectional analysis of the National Health and Nutrition Examination Survey data from 2017 to 2020; multivariable logistic regression examined the CALLY-gallstone association. Restricted cubic splines tested nonlinearity. Subgroup and mediation analyses explored population variations and mediating effects (Conicity, lipid accumulation product, and a body shape index). Receiver operating characteristic curves compared CALLY, systemic immune inflammation index, systemic inflammatory response index, and aggregate index of systemic inflammation predictive performance. RESULTS: After comprehensive adjustments, the highest CALLY quartile had significantly lower gallstone risk vs the lowest (odds ratio 0.56, 95% confidence interval 0.34–0.94). Restricted cubic splines revealed a linear inverse correlation. Subgroup analyses generally supported this inverse relationship. Mediation analysis identified the Conicity index as the strongest mediator (21.47%, P < 0.001), followed by lipid accumulation product and a body shape index (10.72% each, P < 0.001). Receiver operating characteristic analysis showed CALLY (area under the curve = 0.604) outperformed systemic immune inflammation index (0.540), systemic inflammatory response index (0.550), and aggregate index of systemic inflammation (0.546). DISCUSSION: A significant inverse association exists between the CALLY index and gallstone prevalence. The CALLY index demonstrates superior predictive ability compared with other indices, suggesting its potential utility as an objective biomarker for early gallstone risk identification.

Abstract Chronic widespread pain (CWP) remains challenging due to its heterogeneous causes and complex mechanisms. A total of 2920 plasma proteins are analyzed from 29,254 UK Biobank participants. A total of 256 proteins are identified as cross‐sectionally correlated with CWP. A simple (top 10 proteins) and comprehensive (all significant proteins) proteomic‐based score (ProtS) is created for CWP diagnosis, both outperforming and improving the existing clinical score (area under the curve, AUC: 0.801, 0.723, and 0.791 alone, and 0.856 and 0.880 in combination). In addition, the protein score predicted 13‐years risk of pain‐related traits over the body, including pain onset, progression, and intensity; Moreover, it has stronger associations with nociplastic pain and fibromyalgia compared to nociceptive and neuropathic pain, implying a unique protein signature of different pain mechanisms. Finally, among 434 candidate proteins prioritized in the observational analysis, 18 are corroborated with causal relevance by Mendelian randomization, and importantly, four (CA14, DPEP1, LGALS3, and TNF) showed potential as novel drug targets repurposed for treating CWP.
