Randomized Controlled Trial
Examining the impact of permissibility hypercapnia on postoperative delirium among elderly patients undergoing thoracoscopic-laparoscopic esophagectomy: A single-center investigative study.
Objective: This study explores how permissive hypercapnia, a key aspect of lung-protective ventilation, impacts postoperative delirium in elderly patients following thoracic surgery. Methods: A single-center trial at The Second Hospital of Anhui Medical University involved 136 elderly patients undergoing thoracoscopic esophageal cancer resection. Randomly assigned to maintain PaCO 2 35-45 mm Hg (group N) or 46-55 mm Hg (group H). ⋯ Group H had lower pH and higher OI at T2-4 ( P < 0.05). CRP and CAR levels rose less in group H on the first day and 1 week later ( P < 0.05). Conclusions: Maintaining PaCO 2 at 46-55 mm Hg reduces POD incidence, possibly by enhancing rSO 2 levels and stabilizing intraoperative respiration/circulation.

Introduction: A 2003 landmark study identified the prevalence of early trauma-induced coagulopathy (eTIC) at 28% with a strong association with mortality of 8.9%. Over the last 20 years, there have been significant advances in both the fundamental understanding of eTIC and therapeutic interventions. Methods: A retrospective cohort study was performed from 2018 to 2022 on patients ≥18 using prospectively collected data from two level 1 trauma centers and compared to data from 2003. ⋯ In a hybrid logistic regression/Classification and Regression Trees analysis, coagulopathy was independently associated with a 2.1-fold increased risk of mortality (95% confidence interval 1.5-2.9); the predictive quality of the model was excellent [area under the receiver operating characteristic curve (AUROC) 0.932]. Conclusion: The presence of eTIC conferred a higher risk of death across all disease severities and was independently associated with a greater risk of death. Biomarkers of coagulopathy associated with eTIC remain strongly predictive of poor outcome despite advances in trauma care.

Purpose: To evaluate the dose-dependent effect of whole blood (WB) on the outcomes of civilian trauma patients with hemorrhagic shock. Methods: We performed a 2-year (2020-2021) retrospective analysis of the ACS-TQIP dataset. Adult (≥18) trauma patients with a shock index (SI) >1 who received at least 5 units of PRBC and one unit of WB within the first 4 h of admission were included. ⋯ High ratio (≥0.25) group had lower adjusted odds of 24-h mortality (aOR: 0.678, P = 0.021) and in-hospital mortality (aOR: 0.618, P < 0.001) compared to the low ratio group. Conclusions: A higher WB:PRBC ratio was associated with improved early and late mortality in trauma patients with hemorrhagic shock. Given the availability of WB in trauma centers across the United States, at least one unit of WB for every 4 units of packed red blood cells may be administered to improve the survival of hemorrhaging civilian trauma patients.

Background: Histidine-rich glycoprotein (HRG), a potential prognostic factor in sepsis, lacks clarity regarding its relevance in septic-induced shock, disseminated intravascular coagulation (DIC), and acute respiratory distress syndrome (ARDS) pathogenesis. This study investigated the association between HRG concentrations and these critical conditions. Methods: Blood samples were collected from 53 critically ill patients on days 1, 3, 5, and 7 after ICU admission at the Kyushu University Hospital. ⋯ On day 5, an HRG level with a cutoff of 25.5 μg/mL showed a sensitivity of 0.77 and a specificity of 0.75, indicating significantly lower survival rates (log-rank test, P < 0.05). Conclusion: HRG presents a potential intervention for critically ill sepsis patients, providing a novel strategy to enhance outcomes. Further research is needed to explore the therapeutic potential of HRG in sepsis management.

Objective : To explore the association of serum transactive response DNA binding protein 43 (TDP-43) with 28-day poor neurologic outcome in patients with return of spontaneous circulation (ROSC) after cardiac arrest. Methods : We performed a study between January and December 2023. Eligible patients with ROSC following cardiac arrest were enrolled. ⋯ Area under curve of serum TDP-43 (AUC = 0.78) was close to that of serum NSE (AUC = 0.82). A dynamic nomogram prediction model that combined TDP-43, Witnessed CA, IL-6, and NSE was constructed and validated. Conclusion : Elevated serum TDP-43 level was associated with and could be used together with Witnessed CA, IL-6, and NSE to predict poor 28-day neurologic outcome in patients after ROSC following cardiac arrest.
