Background: Growing evidence has found the critical role of circular RNAs (circRNAs) in sepsis-induced acute kidney injury (S-AKI). CircTMCO3 has been found to be involved in tumor microenvironment changes of ovarian cancer. This study aimed to explore whether circTMCO3 functions in S-AKI, and if so, to elucidate the molecular mechanism. ⋯ ZEB2 was identified to be a target of miR-218-5p; its downregulation not only reversed the impacts of miR-218-5p inhibitor on S-AKI, but also mitigated the effects mediated by circTMCO3 upregulation in vitro. Conclusions: CircTMCO3 protects against S-AKI by regulating miR-218-5p/ZEB2 axis, thereby mediating antiapoptotic, antioxidant, and anti-inflammatory activities. This indicates that increasing circTMCO3 expression might be a future therapeutic method for S-AKI.

To determine the risk factors and outcomes of maternal sepsis. ⋯ Gestational age below 37 weeks, lack of antenatal booking, and anemia were found to be significant predictors of maternal sepsis. E. coli was the most common pathogen identified. High mortality rate in maternal sepsis highlights the need for early identification, effective management, and close monitoring to reduce maternal mortality from sepsis.

Background: Acute respiratory distress syndrome (ARDS) is a serious pathological process with high mortality. Ferroptosis is pivotal in sepsis, whose regulatory mechanisms in sepsis-induced ARDS remains unknown. We aimed to determine key ferroptosis-related genes in septic ARDS and investigate therapeutic traditional Chinese medicine. ⋯ Conclusions: Ferroptosis-related genes of IL1B , MAPK 3, and TXN serve as potential diagnostic genes for sepsis-induced ARDS. Sea buckthorn may be therapeutic medication for ARDS. This study provides a new direction for septic ARDS treatment.

Sepsis is a life-threatening organ dysfunction that occurs due to a dysregulated host response to infection. Septic-associated liver injury (SALI) has been closely linked to the prognosis and mortality of sepsis. Recent investigations have delved into the gut-liver axis and its association with SALI, identifying its pivotal role in the gut microbiota. ⋯ Moreover, their metabolites might exacerbate or initiate SALI by modulating immune responses. Nevertheless, interventions to restore the balance of the gut microbiota, such as the administration of probiotics, fecal microbiota transplantation, or dietary adjustments, may ameliorate SALI and enhance the prognosis and survival rates of septic patients. This review aimed to elucidate the function of the gut microbiota in the genesis and procession of SALI and its potential therapeutic value, offering a deeper understanding of the pathogenesis and therapeutic avenues for SALI.
