Tranexamic acid (TXA) administration is recommended in severely injured trauma patients. We examined TXA administration, admission fibrinolysis phenotypes, and clinical outcomes following traumatic injury and hypothesized that TXA was associated with increased multiple organ failure (MOF). ⋯ Administration of TXA following traumatic injury was associated with MOF in the fibrinolysis shutdown and hyperfibrinolysis phenotypes and warrants continued evaluation.

Macrophage, as an integral component of the immune system and the first responder to local damage, is on the front line of defense against infection. Over the past century, the prevailing view of macrophage origin states that all macrophage populations resided in tissues are terminally differentiated and replenished by monocytes from bone-marrow progenitors. Nonetheless, this theory has been reformed by ground-breaking discoveries from the past decades. ⋯ Moreover, multiple lines of evidence have indicated that tissue-resident macrophages play critical roles in maintaining tissue homeostasis and facilitating tissue repair through controlling infection and resolving inflammation. In this review, we summarize the properties of resident macrophages in the lung, spleen, and heart, and further highlight the impact of TRM populations on inflammation control and tissue repair. We also discuss the potential role of local proliferation in maintaining a physiologically stable TRM pool in response to acute inflammation.

Review Meta Analysis
Short-Term Efficacy and Safety of Different Mechanical Hemodynamic Support Devices for Cardiogenic Shock or High-Risk Pci: a Network Meta-Analysis of Thirty-Seven Trials.
With more advanced mechanical hemodynamic support for patients with cardiogenic shock (CS) or high-risk percutaneous coronary intervention (HS-PCI), the morality rate is now significantly lower than before. While previous studies showed that intra-aortic balloon pumping (IABP) did not reduce the risk of mortality in patients with CS compared to conservative treatment, the efficacy in other mechanical circulatory support (MCS) trials was inconsistent. ⋯ Following this analysis, ECMO+IABP might be a more suitable intervention measure in improving short-term mortality for patients with CS and who underwent HS-PCI. However, the result was limited by the lack of sufficient direct comparisons and evidence from randomized controlled trials. Moreover, bleeding and other device-related complications should be considered in clinical applications.
