Background: Sepsis-induced liver injury leads to extensive necroptosis in hepatocytes, which is the main factor of liver dysfunction. This study aims to investigate the protective effect of dexmedetomidine (DEX) on septic liver and to explore whether its molecular mechanism is related to the modulation of necroptosis. Methods: The model of septic liver injury was induced by cecal ligation and puncture (CLP) in rats. ⋯ However, these injuries can be ameliorated by pretreatment with DEX. Meanwhile, Nec-1 pretreatment also reduced the expression of RIP1, RIP3, MLKL, HMGB1, and ROS level. Conclusion: Our study suggests that DEX alleviates septic liver injury, and the mechanism is associated with the inhibition of necroptosis.

[Diagnostic stewardship in outpatient and hospital medicine with focus on microbiological urinary and bloodstream diagnostics].
Targeted infection diagnosis supports decision-making in the rational use of antibiotics usually encompassed as Antibiotic Stewardship (ABS). Similar to ABS, the term "Diagnostic Stewardship" (DGS) is suggested, whereas DGS includes, beneath general, predominantly microbiological infection diagnostics - with specific pathogen detection, conventional via culture or immunology, increasingly also using molecular biological methods. Especially in microbiology, pre-analytics, analytics and post-analytics play an essential role. Pathogen characterization is accompanied by an antimicrobial susceptibility test (with S-I-R classification), which deserves special attention, especially in the context of ABS. All of these aspects are dealt with in this work and represented using two practical examples of urinary and bloodstream diagnostics that are relevant for outpatients and inpatients.
