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. Primary outcomes were 6-h, 24-h, and in-hospital mortality. Secondary outcomes were major complications and hospital and intensive care unit length of stay. Results: A total of 830 trauma patients with a mean (SD) age of 38 (16) were identified. The median [IQR] 4-h WB and PRBC requirements were 2 [2-4] U and 10 [7-15] U, respectively, with a median WB:RBC ratio of 0.2 [0.1-0.3]. Every 0.1 increase in WB:RBC ratio was associated with decreased odds of 24-h mortality (aOR: 0.916, P = 0.035) and in-hospital mortality (aOR: 0.878, P < 0.001). Youden's index identified 0.25 (1 U of WB for every 4 U of PRBC) as the optimal WB:PRBC ratio to reduce 24-h mortality. 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.</p>","PeriodicalId":21667,"journal":{"name":"SHOCK","volume":" ","pages":"344-350"},"PeriodicalIF":2.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141420641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods : We performed a study between January and December 2023. Eligible patients with ROSC following cardiac arrest were enrolled. Their baseline characteristics were collected, and serum levels of TDP-43, tumor necrosis factor-α, interleukin-6 and 10, C-reactive protein, and neuron-specific enolase (NSE) at 24 h after ROSC were measured. The neurologic function was assessed by the cerebral performance category scores on day 28 after ROSC.

Univariate and multivariate logistic regression analyses showed that TDP-43, Witnessed CA, IL-6, and NSE were associated with poor 28-day neurologic outcome (all P < 0.05). Restricted cubic spline analysis revealed that TDP-43 at the serum level of 11.64 pg/mL might be an ideal cutoff value for distinguishing between good and poor neurologic outcomes.

Methods: A retrospective analysis was conducted on a cohort comprising 56 patients diagnosed with septic shock and receiving treatment at the department of critical care medicine of the hospital between January 2021 and March 2023. These patients were divided into two groups based on the prognostic outcome: a survival group consisting of 34 patients and a death group consisting of 22 patients. The determination of vasopressor inflection time and procalcitonin (PCT) inflection time of each patient was undertaken with the initiation of vasopressor therapy serving as the reference point. The vasopressor inflection point was defined as the time when the dosage of vasopressors commenced decreasing, while the PCT inflection point denoted the time when PCT levels began to decline. The incidence of patients reaching the vasopressor and PCT inflection points on the 2nd, 3rd, and 4th days following the initiation of vasopressor therapy was tabulated for both groups. The comparison of inflection points between the two groups at each time point was conducted using Fisher's exact test. Furthermore, logistic regression analysis was employed for univariate prognostic assessment. The diagnostic performance of vasopressor and PCT inflection point was assessed using the four-table method. The discrepancy and consistency between the two methods were evaluated through paired chi-squared test and Kappa consistency test. Results: The vasopressor inflection point demonstrates promising utility in the assessment of short-term prognosis among patients with septic shock, exhibiting sensitivities of 76.4%, 88.2%, and 100%, specificities of 90.9%, 90.9%, and 86.4%, positive predictive values of 92.9%, 93.8%, and 91.9%, and negative predictive values of 71.4% on the 2nd, 3rd, and 4th day, respectively. Correspondingly, the Youden indices were calculated as 0.673, 0.791, and 0.864 on these respective days. Notably, all metrics at comparable intervals surpassed those of the PCT inflection point.

This study aimed to investigate the effects of hydrogen-rich saline (HRS) on renal microcirculation in septic renal failure, and whether Sirt1 was involved in the renoprotective effects of HRS. Rats model of sepsis was established by cecal ligation and puncture, and septic rats were intraperitoneal injected with HRS (10 mL/kg). We found that in sepsis, the degree of glycocalyx shedding was directly proportional to the severity of sepsis. The seven-day survival rate of rats in the HRS+CLP group (70%) was higher than that of the CLP group (30%). HRS improved acidosis and renal function and reduced the release of inflammatory factors (TNF, IL-1β, and IL-6). The endothelial glycocalyx of capillaries in the HRS+CLP group (115 nm) was observed to be significantly thicker than that in the CLP group (44 nm) and EX527 (67.2 nm) groups by electron microscopy, and fewer glycocalyx metabolites (SDC-1, HS, HA, and MMP9) were found in the blood. Compared with the CLP group, HRS reduced renal apoptosis and upregulated Sirt1 expression, and inhibited the NF-κB/MMP9 signaling pathway. In addition, HRS did not damage immune function in septic rats as well.

Specifically, we measured the effects of LFP and rmWD on markers of cerebrovascular and tight junction disruption, neuroinflammation, mature neurons, and perineuronal nets in the cortical site of injury, cortex adjacent to injury, dentate gyrus, and the CA 2/3 area of the hippocampus.

The rmWD animals underwent either injury or isoflurane only (randomly assigned) on each of those 4 days. Seven days after injury, brains were harvested for analysis. Overall, our observations revealed that the most significant disruptions were evident in response to LFP, followed by craniotomy only, whereas rmWD animals showed the least residual changes compared with isoflurane-only controls, supporting consideration of rmWD as a mild injury. LFP led to longer-lasting disruptions, perhaps more representative of moderate TBI. We also report that craniotomy and LFP produced greater disruptions in females relative to males.
