Ferroptosis has been found to play an important role in myocardial ischemia reperfusion (MIR) injury (MIRI). This study aimed to explore whether the improvement effect of Etomidate (Eto) on MIRI was related to ferroptosis. ⋯ Eto attenuated the myocardial injury by inhibiting IR-induced ferroptosis via Nrf2 pathway, which may provide a new idea for clinical reperfusion therapy.

Burn injuries are a common form of traumatic injury that leads to significant morbidity and mortality worldwide. Burn injuries are characterized by inflammatory processes and alterations in numerous organ systems and functions. ⋯ Microbial dysbiosis has been linked to multiple disease states; however, its role in exacerbating acute traumatic injuries, such as burn, is poorly understood. In this article, we review studies that document changes in the intestinal microbiome after burn injury, assess the implications in post-burn pathogenesis, and the potential for further discovery and research.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been spread around the world and is currently affecting global public health. Clinical evidence indicates that the elevated number of peripheral neutrophils and higher ratio of neutrophils-to-lymphocytes are correlated with severe outcomes in COVID-19 patients, suggesting the possible immunopathological role of neutrophils during SARS-CoV-2 infection. As an abundant innate immune cell type, neutrophils are well known for their contributions to antimicrobial defense. ⋯ Herein, in this mini-review, we summarize the recent progress on the potential role of neutrophils during COVID-19-associated inflammatory responses. In particular, we highlight the interactions between neutrophils and viruses as well as the relationship of neutrophils with cytokine storm and thrombosis in COVID-19 patients. Lastly, we discuss the importance of neutrophils as potential therapeutic targets for COVID-19.

Does Chloride Intake at The Early Phase of Septic Shock Resuscitation Impact on Renal Outcome?
Fluid administration is one of the first lines of treatment for hemodynamic management of sepsis and septic shock. Studies investigating the effects of chloride-rich fluids including normal saline on renal function report controversial findings. ⋯ At the early stage of resuscitation of critically ill patients with septic shock, administration of "high-dose" of chloride (> 18 g/48 h) was not associated with renal prognosis.
