Sepsis is characterized by an inappropriate systemic inflammatory response and bacteremia that promote multiorgan failure and mortality. Sphingosine 1-phosphate receptor 2 (S1PR2) modulates endotoxin-induced inflammation in endothelium. However, as a highly expressed S1P receptor in macrophages, its role in regulating macrophage response to bacterial infection remains unclear. ⋯ This study implies that S1PR2, as a critical receptor in macrophage, impairs phagocytosis and antimicrobial defense in the pathogenesis of sepsis. Interventions targeting S1PR2 signaling may serve as promising therapeutic approaches for sepsis.

Review Meta Analysis
N-terminal pro-B-type Natriuretic Peptides' Prognostic Utility Is Overestimated in Meta-analyses Using Study-specific Optimal Diagnostic Thresholds.
N-terminal fragment B-type natriuretic peptide (NT-proBNP) prognostic utility is commonly determined post hoc by identifying a single optimal discrimination threshold tailored to the individual study population. The authors aimed to determine how using these study-specific post hoc thresholds impacts meta-analysis results. ⋯ Post hoc identification of study-specific prognostic biomarker thresholds artificially maximizes biomarker predictive power, resulting in an amplification or overestimation during meta-analysis of these results. This effect is accentuated in small studies.
