Background: The exact molecular mechanisms underlying sepsis remain unclear. Accumulating evidence has shown that noncoding RNAs (ncRNAs) are involved in sepsis and sepsis-associated organ dysfunction (SAOD). Methods: We performed this updated systematic review focusing mainly on research conducted in the last 5 years regarding ncRNAs associated with sepsis and SAOD. ⋯ At a molecular level, inflammation-related pathways, mitochondrial dysfunction, cell apoptosis, and/or oxidative stress were the most extensively studied. Conclusion: This review suggests that ncRNAs could be good biomarkers and therapeutic candidates for sepsis and SAOD. Prospective, large-scale, and multicenter cohort studies should be performed to evaluate specific ncRNAs as biomarkers and test the organ-specific delivery of these regulatory molecules when used as therapeutic targets.

IMPELLA VERSUS EXTRACORPOREAL MEMBRANE OXYGENATION IN CARDIOGENIC SHOCK: A SYSTEMATIC REVIEW AND META-ANALYSIS.
Background: Cardiogenic shock (CS) carries high mortality. The roles of specific mechanical circulatory support (MCS) systems are unclear. We compared the clinical outcomes of Impella versus extracorporal membrane oxygenation (ECMO) in patients with CS. ⋯ There was less risk of bleeding and stroke in the Impella group compared with the ECMO group. Conclusions: In patients with CS, the use of Impella is associated with lower rates of in-hospital mortality, bleeding, and stroke than ECMO. Future randomized studies with adequate sample sizes are needed to confirm these findings.
