Observational Study
Comprehensive Therapeutic Efficacy Analysis of Intravenous Immunoglobulin in Treating Sepsis-induced Coagulopathy: A Single-Center, Retrospective Observational Study.
Objective : The aim of the study is to investigate the efficacy of intravenous immunoglobulin (IVIg) in treating sepsis-induced coagulopathy ( SIC ). Methods : A retrospective controlled analysis was conducted on 230 patients with SIC at Ganzhou People's Hospital from January 2016 to December 2022. All patients were screened using propensity score matching and treated according to the SSC2016 guidelines. ⋯ No significant differences were observed in the duration of fever or vasoactive drug use between the groups. However, the log-rank method indicated a higher 28-day survival rate in the test group ( P < 0.05). Conclusion : IVIg can successfully increase platelet count and coagulation factors, correct coagulation disorders, enhance organ function, and reduce 28-day mortality in patients with SIC .

Background : It is reported that circVMA21 has an inhibition effect on sepsis-induced acute kidney injury (AKI). Therefore, the underlying molecular mechanisms of circVMA21 in AKI are worthy of further investigation. Material and Methods : Lipopolysaccharide (LPS) was used to induce HK2 cell injury. ⋯ Moreover, circVMA21 sponged miR-337-3p, and miR-337-3p targeted ZEB2. The inhibitory effect of circVMA21 on LPS-induced HK2 cell injury was reversed by miR-337-3p overexpression, and ZEB2 overexpression abolished the promotion effect of miR-337-3p on LPS-induced HK2 cell injury. Conclusions : CircVMA21 could inhibit LPS-induced HK2 cell injury via miR-337-3p/ZEB2 axis.

New-onset atrial fibrillation (AF) during sepsis is common, but models designed to stratify stroke risk excluded patients with secondary AF. We assessed the predictive validity of CHA2DS2VASc scores among patients with new-onset AF during sepsis and developed a novel stroke prediction model incorporating presepsis and intrasepsis characteristics. ⋯ Current models do not accurately stratify risk of stroke following new-onset AF secondary to sepsis. New tools are required to guide anticoagulation decisions following new-onset AF in sepsis.

Introduction: Intestinal flora and the translocation of its products, such as muramyl dipeptide (MDP), are common causes of sepsis. MDP is a common activator of the intracellular pattern recognition receptor NOD2, and MDP translocation can cause inflammatory damage to the small intestine and systemic inflammatory responses in rats. Therefore, this study investigated the effects of MDP on the intestinal mucosa and distant organs during sepsis and the role of the NOD2/AMPK/LC3 pathway in MDP-induced mitochondrial dysfunction in the intestinal epithelium. ⋯ Compared to the MDP+LPS groups, the MDP+SPEN+LPS groups had decreased IL-6 and MDP production, increased AMPK and LC3 protein expression, and protected mitochondrial and organ functions. Conclusions: MDP translocation reduced mitochondrial autophagy by regulating the NOD2/AMPK/LC3 pathway, causing mitochondrial dysfunction. SPEN protected against MDP-induced impairment of intestinal epithelial mitochondrial function during sepsis.
